Abstract Quality improvement of care for patients with head and neck cancer remains a constant objective for the multidisciplinary team of physicians managing these patients. The purpose of quality assurance (QA) for head and neck surgical oncology and surgical trials however differs. While QA for the general head and neck patient aims to improve global outcome through structural changes of health-care systems, QA for surgical trials pursues the goal to help providing meaningful results from a clinical trial through the definition of structure, process and outcome measures within the trial. Establishing a QA program for surgical trials is challenging largely due to the variation in the execution of surgical techniques. Within this article, we describe the surgical QA program, which was developed for the phase III European Organisation for Research and Treatment of Cancer (EORTC) 1420 study, a trial assessing swallowing function after transoral surgery compared with radiation therapy. We propose based on our experience to further develop surgical QA for surgical clinical trials by introducing two separate components, one adaptable and one non-adaptable. The adaptable is tailored to the scientific question and specific procedure; the non-adaptable consists of minimal structural requirements of the clinical unit to participate in surgical trials at EORTC as well as guidelines and incentives for protocol adherence based on our experience in EORTC 24954. Finally, we strongly believe that surgical QA designed for clinical trials may serve as a basis for the development of QA surgical guidelines in clinical practice. Highlights • Quality assurance (QA) programs for surgical trials are challenging. • We propose a QA framework consisting of an adaptable and a non-adaptable component. • The adaptable is tailored to the scientific question and specific procedure. • The non-adaptable consists of minimal structural requirements of the clinical unit. • Surgical QA within clinical trials may serve as the basis for guidelines in clinical practice.

Objective: Methylene blue (MB) is frequently administered during fiberoptic endoscopic evaluation of swallowing (FEES) to enhance visualization of pharyngeal bolus transit. However, the safety of MB is being questioned since serious adverse events (AEs) such as hemodynamic instability, hemolysis, and serotonin syndrome were reported. The aim of this study is a systematic analysis of the literature to obtain an evidence-based overview of AEs due to oral administration of MB and to determine its safety as a food dye during swallowing assessment. Methods: A systematic literature search was carried out in PubMed, Embase, and Cochrane Library. Two reviewers independently selected articles describing oral administration of MB as a main diagnostic/therapeutic intervention, dosage, and AEs. Expert opinions, conference papers, sample size < 10, and animal studies were excluded. Level of evidence of the included studies was determined. Results: A total of 2264 unduplicated articles were obtained. Seventeen studies met the inclusion criteria with 100% agreement between the two reviewers. Among these, twelve studies were randomized controlled trials. In a pooled population of 1902 patients receiving oral MB, three serious AEs were reported related to MB. Non-serious AEs showed a dose-related trend and were usually mild and self-limiting. A meta-analysis could not be performed as studies were methodologically too heterogeneous. Conclusion: Serious AEs due to oral administration of MB are rare (n = 3, 0.16%). MB-related non-serious AEs are mild, self-limiting, and show a dose-related trend. These findings indicate that it is safe to use small amounts of MB as a food dye during swallowing examinations. [ABSTRACT FROM AUTHOR]

Background: Use of electronic methods to support informed consent ('eConsent') is increasingly popular in clinical research. This commentary reports the approach taken to implement electronic consent methods and subsequent experiences from a range of studies at the Leeds Clinical Trials Research Unit (CTRU), a large clinical trials unit in the UK. Main text: We implemented a remote eConsent process using the REDCap platform. The process can be used in trials of investigational medicinal products and other intervention types or research designs. Our standard eConsent system focuses on documenting informed consent, with other aspects of consent (e.g. providing information to potential participants and a recruiter discussing the study with each potential participant) occurring outside the system, though trial teams can use electronic methods for these activities where they have ethical approval. Our overall process includes a verbal consent step prior to confidential information being entered onto REDCap and an identity verification step in line with regulator guidance. We considered the regulatory requirements around the system's generation of source documents, how to ensure data protection standards were upheld and how to monitor informed consent within the system. We present four eConsent case studies from the CTRU: two randomised clinical trials and two other health research studies. These illustrate the ways eConsent can be implemented, and lessons learned, including about differences in uptake. Conclusions: We successfully implemented a remote eConsent process at the CTRU across multiple studies. Our case studies highlight benefits of study participants being able to give consent without having to be present at the study site. This may better align with patient preferences and trial site needs and therefore improve recruitment and resilience against external shocks (such as pandemics). Variation in uptake of eConsent may be influenced more by site-level factors than patient preferences, which may not align well with the aspiration towards patient-centred research. Our current process has some limitations, including the provision of all consent-related text in more than one language, and scalability of implementing more than one consent form version at a time. We consider how enhancements in CTRU processes, or external developments, might affect our approach. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this paper is to expand upon some of the issues raised in "An evaluation of a speech and language therapy eating, drinking and swallowing service for adults with intellectual disability" (Crocker et al., 2024). Design/methodology/approach: This commentary outlines considerations for multidisciplinary team working and professional roles both within and beyond the community learning disability team. It discusses models of service delivery and competency frameworks relating to eating, drinking and swallowing services. Findings: Services should be integrated, include a broad multidisciplinary team and aim to increase competency in all contexts supporting people with eating, drinking and swallowing needs. Outcomes of service provision need to be measured outside of individualised care. Originality/value: This paper broadens the discussion of quality of eating, drinking and swallowing services beyond speech and language therapy and considers a whole systems approach.

Background: Swallowing function can become impaired due to primary medical conditions or age‐related presbyphagia, resulting in swallowing disorders, known as dysphagia. Specific manoeuvres that target different musculature have been innovated and researched, but whole‐body exercises (WBE) that target multiple large groups of body systems and muscles have been rarely considered in dysphagia management, despite the causes of dysphagia being often systemic. Aims: To identify intervention studies that have used or incorporated WBE to target swallowing function in humans, and report on their findings. Methods & Procedures: A scoping review was conducted given the paucity and novelty of this topic in research and practice. Key search terms were used to search five major databases on for all human studies published before 28 November 2022. Studies that were not interventional or used animal models were excluded. All swallowing and oromotor‐related outcomes were extracted from the studies. Two researchers independently reviewed all search results following the PRISMA‐ScR guideline before meeting to resolve any disagreements. Main Contribution: Final analysis was conducted on 11 papers that described 10 studies, with 10 papers (9 studies) reporting positive findings for swallowing or oromotor function‐related outcomes. Studies ranged from randomised controlled trials to case studies in design. The study design and populations were heterogeneous, with outcome measures for swallowing and oromotor function ranging from subjective questionnaires to instrumental assessments. Conclusions & Implications: Dysphagia rehabilitation that incorporates WBE as part of a comprehensive programme appears to be more beneficial than either WBE or swallowing‐related interventions alone. This review is an initial attempt to systematically examine the evidence on this topic. There is a need for future research to study how WBE can be used, either alone or combined with traditional swallowing exercises, to influence swallowing function in different healthy and clinical populations. WHAT THIS PAPER ADDS: What is already known on this subject: Dysphagia rehabilitation usually focuses only on the swallowing muscles and structures of the head, neck, and respiratory system. Whole‐body exercise (WBE) and fitness are associated with stronger performance of the tongue muscles, there may be transference potential of WBE to swallowing function. What this paper adds to existing knowledge: This review found 10 studies conducted in the last decade that investigated the inclusion of WBE in programmes intended to improve swallowing and/or oromotor‐related outcomes. The studies varied widely in design and methodology, but most reported evidence in support of the inclusion of WBE to improve or maintain swallowing and/or oromotor‐related functions. What are the potential or actual clinical implications of this work?: There is potential for WBE to have a synergistic effect on swallowing function when combined with traditional swallowing exercises. Future clinical research should compare different rehabilitation approaches with controls. Clinicians should enlist allied health professionals who can provide whole‐body rehabilitation when managing dysphagia. [ABSTRACT FROM AUTHOR]

Most patients diagnosed with tongue carcinoma undergo surgical resection and reconstructive surgery to preserve tongue mobility and swallowing functions. Twenty-four patients who underwent a total or subtotal glossectomy and surgical reconstruction were evaluated for residual taste sensation. The graded filter paper test for all four tastes (sweet, salt, sour, and bitter) was performed on the posterior wall of the oropharynx and on tongue remnants if they were visible from the mouth. Eleven of the 24 patients were aware of their taste disorder after surgery. Four patients with more than 1/2 residual tongue base had no taste complaints, whereas seven of 14 patients with less than 1/3 residual tongue base reported taste abnormalities. Patients who could only tolerate a poor diet or tube feeding tended to have taste complaints (P=0.017). The taste test showed that the taste threshold of the residual tongue was significantly lower compared to controls. The taste threshold was significantly correlated with the remaining volume of tongue base. Patients with >1/2 the tongue base remaining had good taste sensation, whereas those with <1/3 residual tissue had impaired taste. This study suggests that glossectomy strategies aimed at preserving at least half the tongue base may substantially reduce dysgeusia in the patients. [ABSTRACT FROM AUTHOR]

Background: The last three decades have seen a growth in the number of children requiring long-term ventilation. Children with long-term ventilation present with underlying respiratory and neurological conditions that place them at risk of feeding and swallowing difficulties. To date, a scoping review or systematic review investigating the feeding and swallowing outcomes of children with long-term ventilation needs has not been conducted. Aims: This paper describes a protocol for a scoping review of the feeding and swallowing outcomes of children receiving long-term ventilation. Methods: This scoping review protocol will utilize the Joanna Briggs Institute scoping review methodology guideline. Our review will focus on the feeding and swallowing outcomes of children aged 0 to 18 years with long-term ventilation needs. A full search strategy initially created by the authors and a research librarian was conducted on the PubMed database. Following this, pilot testing took place to determine discrepancies in eligibility criteria. A full search strategy will be conducted across several databases. A data extraction form has been developed by the authors and will be used during the scoping review process. Discussion: This protocol has been created to provide a rigorous and comprehensive basis for undertaking a scoping review. All necessary steps have been completed in order to commence the scoping review. Registration: This scoping review protocol was registered on Open Science Framework on the 26
th November 2021 (Registration DOI 10.17605/OSF.IO/NQBPD). [ABSTRACT FROM AUTHOR]- Published

Background: Endovascular clot retrieval (ECR) is known to reduce global disability at 3 months post stroke however limited research exists regarding the trajectory of specific clinical impairments including language, swallowing and cognitive deficits between onset and 3 months. Aims: To assess language, swallowing, and cognitive performance following ECR and explore whether impairment severity is correlated with modified Thrombolysis in Cerebral Infarction score (mTICI), stroke severity or quality of life (QoL). Methods: Assessment was completed within 7 days (T1), 1 month (T2) and 3 months (T3) post‐stroke. Performance was measured with the Functional Oral Intake Scale (FOIS), Repeatable Battery for Assessment of Neuropsychological Status (RBANS), Trail Making Test (TMT A and B) and Brixton Spatial Awareness Test. The Western Aphasia Battery (WAB) was used for left hemisphere stroke. QoL was measured with the Stroke and Aphasia Quality of Life Scale. Results: Twenty‐five participants (median 72 years; 64% male) were prospectively recruited following ECR. High reperfusion success (68% mTICI 3) and low stroke severity post ECR (median 24 h NIHSS = 3, IQR 7–18) were noted. At T1, 10 participants presented with aphasia, eight required a modified diet and 20 had impaired cognition. At T3 all had recovered to a normal oral diet, 39% had persistent cognitive impairment and 45% of patients with left hemisphere stroke remained aphasic. Performance on the WAB, FOIS, RBANS and TMT changed significantly over time (all p < 0.05). The severity score at T1 for all measures, excluding TMT B and Brixton, was significantly correlated with 24 h NIHSS. WAB scores at T3 were correlated with QoL (r = 0.618; p = 0.043). Conclusion: This exploratory study found the longitudinal performance of language, swallowing and cognition significantly improved over time and severity in the first‐week post‐ECR was correlated with 24 h NIHSS rather than the degree of reperfusion. WHAT THIS PAPER ADDS: What is already known on the subject: Randomised control trials have demonstrated the benefit of ECR in patients with ischemic stroke using global measures of disability and function. Limited research exists regarding the trajectory of specific clinical impairments including language, swallowing and cognitive deficits. There is also a reliance on screening assessments and a lack of consideration of the influence of co‐occurring impairments. What this paper adds to existing knowledge: This prospective study is amongst the first to explore the longitudinal trajectory of language, swallowing and cognitive impairment using a standardised assessment battery. Twenty‐four‐hour NIHSS was significantly correlated with language, swallowing, global cognition and some measures of executive function. Language performance post ECR was correlated with domain‐specific cognitive assessment of attention, immediate memory and delayed memory, which differed from swallowing performance post ECR that correlated with measures of executive function. What are the potential or actual clinical implications of this work?: It is important for speech‐language pathologists and the wider medical team to monitor language, swallowing and cognitive performance post ECR regardless of treatment success. Stroke severity at 24 h post‐ECR influences the severity of language, swallowing and cognitive impairments. [ABSTRACT FROM AUTHOR]

Background: Competent clinical reasoning forms the foundation for effective and efficient clinical swallowing examination (CSE) and consequent dysphagia management decisions. While the nature of initial CSEs has been evaluated, it remains unclear how new information gathered by speech–language therapists (SLTs) throughout a patient's acute‐care journey is integrated into their initial clinical reasoning and management processes and used to review and revise initial management recommendations. Aims: To understand how SLTs' clinical reasoning and decision‐making regarding dysphagia assessment and management evolve as patients transition through acute hospital care from referral to discharge. Methods & Procedures: A longitudinal, qualitative approach was employed to gather information from two SLTs who managed six patients at a metropolitan acute‐care hospital. A retrospective 'think‐aloud' protocol was utilized to prompt SLTs regarding their clinical reasoning and decision‐making processes during initial and subsequent CSEs and patient interactions. Three types of concept maps were created based on these interviews: a descriptive concept map, a reasoning map and a hypothesis map. All concept maps were evaluated regarding their overall structure, facts gathered, types of reasoning engaged in (inductive versus deductive), types of hypotheses generated, and the diagnosis and management recommendations made following initial CSE and during subsequent dysphagia management. Outcomes & Results: Initial CSEs involved a rich process of fact‐gathering, that was predominantly led by inductive reasoning (hypothesis generation) and some application of deductive reasoning (hypothesis testing), with the primary aims of determining the presence of dysphagia and identifying the safest diet and fluid recommendations. During follow‐up assessments, SLTs engaged in increasingly more deductive testing of initial hypotheses, including fact‐gathering aimed at determining the tolerance of current diet and fluid recommendations or the suitability for diet and/or fluid upgrade and less inductive reasoning. Consistent with this aim, SLTs' hypotheses were focused primarily on airway protection and medical status during the follow‐up phase. Overall, both initial and follow‐up swallowing assessments were targeted primarily at identifying suitable management recommendations, and less so on identifying and formulating diagnoses. None of the patients presented with adverse respiratory and/or swallowing outcomes during admission and following discharge from speech pathology. Conclusions & Implications: Swallowing assessment and management across the acute‐care journey was observed as a high‐quality, patient‐centred process characterized by iterative cycles of inductive and deductive reasoning. This approach appears to maximize efficiency without compromising the quality of care. The outcomes of this research encourage further investigation and translation to tertiary and post‐professional education contexts as a clear understanding of the processes involved in reaching diagnoses and management recommendations can inform career‐long refinement of clinical skills. WHAT THIS PAPER ADDS: What is already known on the subject: SLTs' clinical reasoning processes during initial CSE employ iterative cycles of inductive and deductive reasoning, reflecting a patient‐centred assessment process. To date it is unknown how SLTs engage in clinical reasoning during follow‐up assessments of swallowing function, how they assess the appropriateness of initial management recommendations and how this relates to patient outcomes. What this paper adds to the existing knowledge: Our longitudinal evaluation of clinical reasoning and decision‐making patterns related to swallowing management in acute care demonstrated that SLTs tailored their processes to each patient's presentation. There was an emphasis on monitoring the suitability of the initial management recommendations and the potential for upgrade of diet or compensatory swallowing strategies. The iterative cycles of inductive and deductive reasoning reflect efficient decision‐making processes that maintain high‐quality clinical care within the acute environment. What are the potential or actual clinical implications of this work?: Employing efficient and high‐quality clinical reasoning is a hallmark of good dysphagia practice in maximizing positive patient outcomes. Developing approaches to understanding and making explicit clinical reasoning processes of experienced clinicians may assist SLTs of all developmental stages to provide high standards of care.

- Abstract
Background: Prophylactic swallowing exercises (PSE) during radiotherapy can significantly reduce dysphagia after radiotherapy in head and neck cancer (HNC). However, its positive effects are hampered by low adherence rates during the burdensome therapy period. Hence, the main goal of this multicenter randomized controlled trial (RCT) was to investigate the effect of 3 different service-delivery modes on actual patients' adherence. Methods: A total of 148 oropharyngeal cancer patients treated with primary (chemo)radiotherapy were randomly assigned to a 4 weeks PSE program, either diary-supported (paper group; n = 49), app-supported (app group; n = 49) or therapist-supported (therapist group; n = 50). Participants practiced 5 days/week, daily alternating tongue strengthening exercises with chin tuck against resistance exercises. Adherence was measured as the percentage of completed exercise repetitions per week (%reps). Statistical analysis was performed by means of SPSSv27, using Linear Mixed-effects Models with post hoc pairwise testing and Bonferroni-Holm correction. Results: Adherence and evolution of adherence over time was significantly different between the three groups (p <.001). Adherence rates decreased in all three groups during the 4 training weeks (p <.001). During all 4 weeks, the therapist group achieved the highest adherence rates, whilst the app group showed the lowest adherence rates. Conclusions: PSE adherence decreased during the first 4 radiotherapy weeks regardless of group, but with a significant difference between groups. The therapist group achieved the highest adherence rates with a rather limited decline, therefore, increasing the face-to-face contact with a speech-language therapist can overcome the well-known problem of low adherence to PSE in this population.

Current speech-language pathology (SLP) services in Cambodia are limited in scope, service accessibility and integration into government systems. However, momentum is growing to develop an internationally recognised profession. This paper examines the depth and breadth of SLP support available to people with communication and/or swallowing difficulties in relation the Sustainable Development Goals (SDGs). Qualitative interview data collected from service facilities (n = 13) and speech therapy practitioners (n = 27) were mapped and analysed for accessibility and scope of SLP services. Data revealed a workforce density of 0.16:100 000. Disparity in service accessibility was identified between provincial and urban locations, adult and paediatric populations and range of practice areas. The findings demonstrate the importance of partnerships (SDG 17) among government departments, non-government organisations and private sector entities to establish a sustainable and culturally responsive SLP profession in Cambodia. Although there is no Cambodian university training program, there is a growing momentum and local commitment to establishing a workforce to support Cambodians with communication and/or swallowing difficulties. This commentary paper focuses on good health and well-being (SDG 3), decent work and economic growth (SDG 8), reduced inequalities (SDG 10), and also addresses no poverty (SDG 1), quality education (SDG 4) and partnerships for the goals (SDG 17).

Speech and swallowing are complex sensorimotor behaviors accomplished using shared vocal tract anatomy. Efficient swallowing and accurate speech require a coordinated interplay between multiple streams of sensory feedback and skilled motor behaviors. Due to the shared anatomy, speech and swallowing are often both impacted in individuals with various neurogenic and developmental diseases, disorders, or injuries. In this review paper, we present an integrated biophysiological framework for modeling how sensory and motor changes alter functional oropharyngeal behaviors of speech and swallowing, as well as the potential downstream effects to the related areas of language and literacy. We discuss this framework with specific reference to individuals with Down syndrome (DS). Individuals with DS experience known craniofacial anomalies that impact their oropharyngeal somatosensation and skilled motor output for functional oral-pharyngeal activities such as speech and swallowing. Given the increased risk of dysphagia and "silent" aspiration in individuals with DS, it is likely somatosensory deficits are present as well. The purpose of this paper is to review the functional impact of structural and sensory alterations on skilled orofacial behaviors in DS as well as related skills in language and literacy development. We briefly discuss how the basis of this framework can be used to direct future research studies in swallowing, speech, and language and be applied to other clinical populations.

Background: : Dysphagia is prevalent in subjects with Parkinson's disease (PD). Swallowing intervention to improve or maintain swallowing function is of major importance as dysphagia may considerably impact physical and psycho‐social health. Aims: : A mixed methods systematic review was conducted to summarize and appraise literature reporting (1) effects of behavioural interventions for swallowing in individuals with PD; and (2) participants' perspectives of swallowing interventions. Methods & Procedures: : Electronic databases were searched systematically in July 2020 for articles published between 2014 and 2020. In addition, studies published between 2000 and 2014 were identified non‐systematically through previous reviews. Peer‐reviewed quantitative and qualitative research in English or German documenting behavioural interventions for swallowing in individuals with a diagnosis of PD was eligible for inclusion. Participants at all disease stages were included. Behavioural interventions included rehabilitative and compensatory strategies. Studies reporting swallowing outcomes with and without a comparative group were included. For each study, the National Health and Medical Research Council level of evidence was defined. Included studies were critically appraised using the Standard Quality Assessment Criteria for Evaluating Primary Research Papers from a Variety of Fields. An integrated synthesis was performed after separate analysis of effect data and data reflecting participants' experiences. This review was conducted based on published JBI methodology and the guideline from the Preferred Reporting Items for Systematic Reviews and Meta‐Analysis system was followed. Main Contribution: : A total of 33 studies published in English met the inclusion criteria. Thirty‐one studies reported quantitative data, one was qualitative and one was mixed methods. Intervention effects on swallowing function, swallowing safety and swallowing‐related quality of life were reported for various treatment approaches. Three studies explored how participants perceived the intervention. Overriding themes including subjects' views regarding treatment schedules and levels of effort or comfort associated with the intervention were identified across these studies. Combining evidence of intervention effects and subjects' experiences was possible for one rehabilitative and one compensatory intervention. Conclusions & Implications: : Beneficial effects of swallowing interventions have been reported; however, most experiments were case studies of variable methodological quality. Randomized‐controlled trials with robust methodology to explore treatment effects in larger samples is needed to guide clinical practice. Research reporting subjects' views is scarce. More studies exploring how individuals perceive behavioural interventions for swallowing are necessary to inform clinical decision‐making. WHAT THIS PAPER ADDS: What is already known on the subject: Dysphagia is common in individuals with PD. Swallowing intervention is of major importance as dysphagia may negatively affect physical and psycho‐social health of subjects with PD. What this study adds: Beneficial effects of behavioural interventions for swallowing, including rehabilitative and compensatory strategies, have been reported; however, available data are mostly based on case studies of variable quality. Data on how participants perceive specific behavioural interventions are lacking. Based on the available data, integration of efficacy data and individuals' experiences is limited. What are the clinical implications of this work?: Given the current evidence of intervention effects and individuals' views on behavioural treatment strategies, interventions implemented into clinical practice require careful evaluation on a case‐by‐case basis. More high‐quality research is needed to examine interventions' short‐ and long‐term effects in larger samples to guide clinical practice. In addition to studies evaluating intervention effects, research exploring participants' experiences with interventions is required as a foundation for clinical decision‐making.

Between September 2019 and December 2023, a total of 612 wild birds representing 16 orders, 33 families, 60 genera, and 78 species from nine provinces of Iran with different climates namely Hamedan (n = 54), Sistan-va-Baluchestan (n = 372), Kerman (n = 73), South Khorasan (n = 52), Mazandaran (n = 7), Chaharmahal-va-Bakhtiari (n = 2), Gilan (n = 2), Golestan (n = 18), North Khorasan (n = 9), and Razavi Khorasan (n = 23) were examined for chewing lice infestation. Naked eye examination revealed that 58 birds (9.5%) were infested with at least one chewing louse species. Collected lice specimens belonged to 28 species from the families Philopteridae, Menoponidae and Laemobothriidae including Strigiphilus strigis (n = 55, 15.6%), Falcolipeurus quadripustulatus (n = 41, 11.6%), Craspedorrhynchus platystomus (n = 40, 11.3%), Colpocephalum turbinatum (n = 36, 10.2%), Laemobothrion maximum (n = 25, 7.1%), Nosopon lucidum (n = 20, 5.6%), Degeeriella fulva (n = 18, 5.1%), Colpocephalum eucarenum (n = 16, 4.5%), Laemobothrion vulturis (n = 15, 4.2%), Anaticola crassicornis (n = 13, 3.7%), Craspedorrhynchus aquilinus (n = 9, 2.5%), Degeeriella fusca (n = 7, 2.0%), Aegypoecus trigonoceps (n = 7, 2.0%), Quadraceps obscurus (n = 6, 1.7%), Colpocephalum impressum (n = 6, 1.7%), Trinoton querquedulae (n = 6, 1.7%), Colpocephalum heterosoma (n = 5, 1.4%), Colpocephalum nanum (n = 5, 1.4%), Lunaceps holophaeus (n = 4, 1.1%), Quadraceps spp. (n = 4, 1.1%), Actornithophilus uniseriatus (n = 2, 0.6%), Nosopon chanabense (n = 2, 0.6%), Actornithophilus cornutus (n = 1, 0.3%), Cuclotogaster heterographus (n = 1, 0.3%), Falcolipeurus suturalis (n = 1, 0.3%), Laemobothrion atrum (n = 1, 0.3%), Colpocephalum gypsi (n = 1, 0.3%), and Rallicola cuspidatus (n = 1, 0.3%). All of these species except six, i.e., Trinoton spp., C. aquilinus, L. vulturis, L. maximum, C. impressum, C. turbinatum, and C. heterographus are recorded for the first time from Iran. This study is the largest epidemiological study to date performed in the country. Data reported herein contribute to our knowledge about diversity of avian chewing lice from wild birds in Iran. In this paper, an updated checklist of louse species reported from Iran according to their avian hosts is presented. [ABSTRACT FROM AUTHOR]

Background: We previously developed grading metrics for quantitative performance measurement for simulated endoscopic sleeve gastroplasty (ESG) to create a scalar reference to classify subjects into experts and novices. In this work, we used synthetic data generation and expanded our skill level analysis using machine learning techniques. Methods: We used the synthetic data generation algorithm SMOTE to expand and balance our dataset of seven actual simulated ESG procedures using synthetic data. We performed optimization to seek optimum metrics to classify experts and novices by identifying the most critical and distinctive sub-tasks. We used support vector machine (SVM), AdaBoost, K-nearest neighbors (KNN) Kernel Fisher discriminant analysis (KFDA), random forest, and decision tree classifiers to classify surgeons as experts or novices after grading. Furthermore, we used an optimization model to create weights for each task and separate the clusters by maximizing the distance between the expert and novice scores. Results: We split our dataset into a training set of 15 samples and a testing dataset of five samples. We put this dataset through six classifiers, SVM, KFDA, AdaBoost, KNN, random forest, and decision tree, resulting in 0.94, 0.94, 1.00, 1.00, 1.00, and 1.00 accuracy, respectively, for training and 1.00 accuracy for the testing results for SVM and AdaBoost. Our optimization model maximized the distance between the expert and novice groups from 2 to 53.72. Conclusion: This paper shows that feature reduction, in combination with classification algorithms such as SVM and KNN, can be used in tandem to classify endoscopists as experts or novices based on their results recorded using our grading metrics. Furthermore, this work introduces a non-linear constraint optimization to separate the two clusters and find the most important tasks using weights. [ABSTRACT FROM AUTHOR]

Background: Ultrasound (US) is not widely used as part of the speech and language therapy (SLT) clinical toolkit. The COVID‐19 pandemic has intensified interest in US as an alternative to SLT instrumental tools such as the videofluoroscopic swallowing study (VFSS), fibreoptic endoscopic evaluation of swallowing (FEES) and endoscopic evaluation of the larynx (EEL) as a non‐invasive, non‐aerosol‐generating procedure that can be delivered at the bedside to assess swallowing and/or laryngeal function. To establish the appropriacy of routine US use, and in response to a national professional body request for a position statement, a group of expert SLTs conducted a rapid review of the literature. Aim: To explore critically the clinical utility of US as an assessment tool for swallowing and laryngeal function in adults. Methods & Procedures: A rapid review of four databases was completed to identify articles using US to assess swallowing and/or laryngeal function in adults compared with reference tests (VFSS/FEES/EEL/validated outcome measure). Screening was completed according to predefined inclusion/exclusion criteria and 10% of abstracts were rescreened to assess reliability. Data were extracted from full texts using a predeveloped form. The QUADAS‐2 tool was used for quality ratings. Information from included studies was summarized using narrative synthesis and visual illustration. Outcomes & Results: Ten papers used US to assess swallowing, and 13 to assess laryngeal function. All were peer‐reviewed primary studies across a range of clinical populations and with a wide geographical spread. Four papers had an overall low risk of bias, but the remaining 19 had at least one domain where risk of bias was judged as high or unclear. Applicability concerns were identified in all papers. The papers that used US to assess swallowing varied widely in terms of the anatomical structures assessed and methodology employed. The papers assessing laryngeal function were more homogenous in their methodology. Sensitivity and specificity data were provided for 12 of the laryngeal function papers with ranges of 64.3–100% and 48.5–100%, respectively. Conclusions & Implications: There is burgeoning evidence to support the use of US as an adjunct to SLT clinical assessment of swallowing and laryngeal function. However, the current literature does not support its use as a tool in isolation. Further research is required to establish reliability in US assessment as well as clear SLT‐driven protocols and training. What this paper addsWhat is already known on the subjectUS has demonstrated potential as an assessment tool for objective parameters of swallowing. Its use for laryngeal assessment (gross vocal fold movement) is also widely recognized within the literature. This review appraised the literature related to US as an alternative or adjunctive tool for the assessment of swallowing and laryngeal function.What this paper adds to existing knowledgeThis paper identifies that the current evidence base for US as a swallowing or laryngeal assessment tool is heterogenous and of variable quality. No study combined the assessment of swallowing and laryngeal function, and only two studies assessed more than one parameter of swallowing, limiting the clinical application of the results.What are the potential or actual clinical implications of this work?This review shows that US is a non‐invasive accessible tool that can offer a detailed focal assessment of swallowing and laryngeal function, such as hyoid displacement and vocal fold mobility. With the development of protocols, training packages and competency standards, US has the potential to be used as an adjunct to SLT assessment of swallowing and laryngeal function. There is not currently enough evidence to support the use of US as a stand‐alone tool for SLT assessment of swallowing or laryngeal function. [ABSTRACT FROM AUTHOR]

Communication is central to the accomplishment of each of the United Nations' 17 Sustainable Development Goals (SDGs) and is a fundamental human right. This special issue of the International Journal of Speech-Language Pathology (IJSLP, vol. 25, no. 1) is dedicated to communication, swallowing and the SDGs; particularly focussing on people with communication and/or swallowing disability and those who support them. The papers in the special issue of IJSLP demonstrate that successful communication is necessary for realisation of all 17 SDGs at both a global and an individual level and advance the international call for SDG 18: Communication for All. The 36 papers address all 17 goals, focussing on poverty, hunger, health, education, work, innovation, climate, cities, land, oceans, justice, and partnerships. Authors worked and undertook their research in Australia, Austria, Benin, Cambodia, Cameroon, Canada, China, Columbia, Denmark, Egypt, Ethiopia, Ghana, Greece, Iceland, India, Iraq, Ireland, Italy, Jordan, Kenya, Lebanon, Maldives, Mozambique, Nepal, New Zealand, Nigeria, State of Palestine, Peru, Philippines, Rwanda, Serbia, South Africa, Uganda, UK, USA, Vietnam. Communication for all is essential for the achievement of the SDGs, "peace and prosperity for people and the planet" (United Nations, 2015a). Achievement of the SDGs is the role of all; including communication specialists, people with communication/swallowing disability, their families and communities. [ABSTRACT FROM AUTHOR]

Background: While the relationship between speech, language and communication needs (SLCN) and mental health difficulties has been recognized, speech and language therapists (SLTs), and mental health professionals face challenges in assessing and treating children with these co‐occurring needs. There exists a gap in the evidence base for best practice for professionals working with children and young people (CYP) who experience difficulties in both areas. Aims: To explore the views of SLTs and mental health clinicians about their experiences of working with CYP exhibiting co‐occurring SLCN and mental health difficulties. Methods & Procedures: Semi‐structured interviews were conducted with eight SLTs and six mental health professionals, including psychotherapists, clinical psychologists, play therapists and counsellors, with experience working with CYP with SLCN. Interviews were analysed using reflexive thematic analysis and themes were identified from the data. Outcomes & Results: Participants felt that SLCN and mental health difficulties frequently co‐occur. Participants described how CYP with SLCN and mental health issues commonly experience difficulties across and between the domains of language and cognition, emotional well‐being and challenging behaviour. Findings suggest that there are organizational limitations in the fields of SLT and mental health that have implications for the efficacy of assessment and treatment of CYP with SLCN and mental health difficulties. Traditional talking therapies were perceived to be inaccessible and ineffective for CYP with SLCN and mental health difficulties. Interventions blending behaviour and emotion programmes with language and communication interventions were considered potentially beneficial. Conclusions & Implications: Future research should explore and evaluate current services and service set‐up in SLT and mental health. The findings from this study have important implications for the efficacy of treatments provided to this population suggesting that more research needs to be done into effective diagnosis and interventions for this population. WHAT THIS PAPER ADDS: What is already known on the subject: Research suggests that CYP with SLCN, such as developmental language disorder (DLD), are likely to experience mental health difficulties including depression, anxiety and poor emotional well‐being. CYP who experience difficulties with SLCN and poor mental health are not well understood and this area remains under‐researched. This has implications for clinician knowledge and therefore the effective diagnosis and treatment of children and adolescents experiencing SLCN and mental health difficulties. In addition, little is known about the accessibility of talking therapies to CYP presenting with SLCN and mental health difficulties. What this paper adds to existing knowledge: SLCN issues are understood by SLTs and mental health issues are understood by mental health professionals, but where these co‐occur difficulties exist for the diagnostic process, with professionals perceiving that CYP in this category are often undiagnosed or misdiagnosed. Organizational boundaries between SLT and mental health were perceived to contribute to a lack of understanding of SLCN and mental health needs, which has implications for effective diagnosis and treatment. Traditional talking therapies were thought to be inaccessible for CYP with SLCN and mental health difficulties. Interventions used in both SLT and psychotherapy were perceived as clinically useful if combined. What are the potential or actual clinical implications of this work?: This paper highlights implications for the accessibility and efficacy of the assessment and treatment provided to this population and to the organization of services currently treating this group of CYP. A direction for future research would be to undertake service evaluations and intervention‐based studies. [ABSTRACT FROM AUTHOR]

Dehydration is a common problem among older adults. It can seriously affect their health and wellbeing and sometimes leads to death, given the diminution of thirst sensation as we age. It is, therefore, essential to keep older adults properly hydrated by monitoring their fluid intake and estimating how much they drink. This paper aims to investigate the effect of surface electromyography (sEMG) features on the detection of drinking events and estimation of the amount of water swallowed per sip. Eleven individuals took part in the study, with data collected over two days. We investigated the best combination of a pool of twenty-six time and frequency domain sEMG features using five classifiers and seven regressors. Results revealed an average F-score over two days of 77.5 ± 1.35 % in distinguishing the drinking events from non-drinking events using three global features and 85.5 ± 1.00 % using three subject-specific features. The average volume estimation RMSE was 6.83 ± 0.14 mL using one single global feature and 6.34 ± 0.12 mL using a single subject-specific feature. These promising results validate and encourage the potential use of sEMG as an essential factor for monitoring and estimating the amount of fluid intake. [ABSTRACT FROM AUTHOR]

Despite swallowing being a frequently performed daily function, it is highly complex. For a safe swallow to occur, muscles within the head, neck, and thorax need to contract in a concerted pattern, controlled by several swallowing centers at multiple levels of the central nervous system, including the midbrain, cerebral cortex, and cerebellum in addition to five cranial nerves. Dysphagia, or difficulty swallowing, is caused by a long list of pathologic processes and diseases, which can interfere with various stages along the swallowing sensorimotor pathway. When present, dysphagia leads to increased mortality, morbidity, hospital length of stay, and reduced quality of life. Current dysphagia management approaches, such as altering the texture and consistency of foods and fluids and teaching patients rehabilitative exercises, have been broadly unchanged for many years and, in the case of texture modification, are of uncertain effectiveness. However, evidence is emerging in support of new medication-based and neuromodulatory treatment approaches. Regarding medication-based therapies, most research has focused on capsaicinoids, which studies have shown are able to improve swallowing in patients with post-stroke dysphagia. Separately, albeit convergently, in the field of neuromodulation, there is a growing and positive evidential base behind three non-invasive brain stimulation techniques: repetitive transcranial magnetic stimulation (rTMS), transcranial direct current stimulation (TDCS), and pharyngeal electrical stimulation (PES). Should some or all of these emerging therapies fulfill their promise, dysphagia-related patient outcomes may be improved. This paper describes the current state of our understanding regarding new medication and neuromodulation-based neurogenic oropharyngeal dysphagia treatments. [ABSTRACT FROM AUTHOR]

Introduction: Dysphagia affects up to 70% of care home residents, increasing morbidity and hospital admissions. Speech and language therapists make recommendations to support safe nutrition but have limited capacity to offer ongoing guidance. This study aimed to understand if recommendations made to support safe and effective care are implemented and how these relate to the actual care delivered. Methods: Eleven mealtimes with residents with dysphagia were observed during 2020 using a tool capturing 12 elements of expected practice. Staff actions during mealtimes were compared with adherence to residents' care plans and speech and language therapist recommendations. Results: Written recommendations predominantly focused on food and fluid modification. Observations (n = 66) revealed food texture, posture, and alertness were adhered to on 90% of occasions, but alternating food and drink, prompting and ensuring swallow completed adherence was less than 60%. Thickened fluids frequently did not align with required International Dysphagia Diet Standardisation Initiative levels. Nutrition care provided in the dining room was less safe due to a lack of designated supervision. Conclusion: Care homes need to be supported to establish a safe swallowing culture to improve residents' safety and care experience. WHAT THIS PAPER ADDS: What is already known on this subject?: Dysphagia is associated with considerable morbidity and mortality and has been identified as an independent risk factor for mortality in nursing home residents.There is evidence that compensatory swallowing strategies, safe feeding advice and dietary modifications can reduce the risk of aspiration pneumonia.Care for nursing home residents at mealtimes is often task‐centred and delegated to those with limited training and who lack knowledge of useful strategies to support the nutrition and hydration needs of residents with dysphagia. What this study adds?: Written advice from speech and language therapists on safe nutrition and hydration for residents with dysphagia is focused mainly on food and fluid modification.Nurses and healthcare assistants have limited understanding of International Dysphagia Diet Standardisation Initiative levels or safe swallowing strategies and recommended practices to support safe nutrition care for residents with dysphagia are inconsistently applied especially when residents are eating in dining areas.Care homes are not aware of Royal College of Speech and Language Therapists guidance on how safe nutrition care of residents with dysphagia should be supported. What are the clinical implications of this work?: Care homes need to prioritise a safe swallowing culture that ensures that residents with swallowing difficulties are assisted to eat and drink in a way that enhances their mealtime experience and minimises adverse events that may result in hospital admission.Speech and language therapists could play an important role in training and supporting care home staff to understand and use safe swallowing strategies with residents with dysphagia.The Royal College of Speech and Language Therapists could provide more assistance to care homes to support and guide them in how to implement safe feeding routines.Care home staff have limited knowledge about how to implement safe feeding routines and need more guidance from speech and language specialists on how they can support residents with dysphagia to eat safely.Creating a safe swallowing culture within care homes could help to improve nutrition care and enhance patient safety.

Background: Speech and language therapists and nurses need to work together to keep patients with swallowing difficulties safe throughout their acute stroke admission. Speech and language therapists make recommendations for safe swallowing following assessment and nurses put recommendations into practice and monitor how patients cope. There has been little research into the everyday realities of ongoing swallow safety management by these two disciplines. Patient safety research in other fields of healthcare indicates that safety can be enhanced through understanding the cultural context in which risk decisions are made. Aims: To generate new understanding for how speech and language therapists (SLTs) and nurses share information for ongoing management of swallows safety on stroke units. Methods & Procedures: An ethnographic methodology involving 40 weeks of fieldwork on three stroke wards in England between 2015 and 2017. Fieldwork observation (357 h) and interviews with 43 members of SLT and nursing staff. Observational and interview data were analysed iteratively using techniques from the constant comparative method to create a thematically organized explanation. Outcomes & Results: An explanation for how disciplinary differences in time and space influenced how SLT and nursing staff shared information for ongoing management of swallow safety, based around three themes: (1) SLTs and nurses were aligned in concern for swallow safety across all information‐sharing routes; however, (2) ambiguity was introduced by the need for the information contained in swallowing recommendations to travel across time, creating dilemmas for nurses. Patients could improve or deteriorate after recommendations were made and nurses had competing demands on their time. Ambiguity had consequences for (3) critical incident reporting and relationships. SLTs experienced dilemmas over how to act when recommendations were not followed. Conclusions & Implications: This study provides new understanding for patient safety dilemmas associated with the enactment and oversight of swallowing recommendations in context, on stroke wards. Findings can support SLTs and nurses to explore together how information for ongoing dysphagia management can be safely implemented within ward realities and kept up to date. This could include considering nursing capacity to act when SLTs are not there, mealtime staffing and SLT 7‐day working. Together they can review their understanding of risk and preferred local and formal routes for learning from it. What this paper adds: What is already known on the subject: It is known that information to keep swallowing safe is shared through swallowing recommendations, which are understood to involve a balance of risks between optimizing the safety of the swallow mechanism and maintaining physiological and emotional health. There is increasing appreciation from patient safety research, of the importance of understanding the context in which hospital staff make decisions about risk and patient safety. What this paper adds to existing knowledge: The paper provides new empirical understanding for the complexities of risk management associated with SLT and nursing interactions and roles with respect to ongoing swallow safety. What are the potential or actual clinical implications of this work?: Findings can underpin SLT and nurse discussion about how swallow safety could be improved in their own settings.

Soar, Naomi, Birns, Jonathan, Sommerville, Peter, Lang, Alex, and Archer, Sally
- Abstract
Background: Patients with dysphagia may consider eating and drinking with acknowledged risk (EDAR) instead of artificial hydration/nutrition. Timely consideration of complex issues is required including dysphagia reversibility, risk/benefit discussions, patient wishes, their capacity and best interests. Objective: This study aimed to establish if EDAR protocols improve care through a systematic literature review with a secondary aim to explore important factors for the development and success of a protocol. Methods: PUBMED, MEDLINE, CINAHL and EMBASE were searched for English language articles to May 2019 with terms related to EDAR, dysphagia and end of life. Articles were agreed for inclusion by three independent reviewers. Levels of evidence were assessed using the modified Sackett scale. Study themes were identified and discussed. Results: 8 articles met the inclusion criteria with varied methodology. The highest level of evidence was III (cohort study). Most were limited to patients with dementia, stroke, in older person's wards or residential homes. Three articles described a systematic approach to EDAR for in-patients, reporting reductions in days nil-by-mouth until feeding plans are made and improvements in documentation of decision making, nutrition plans and capacity assessment. Five papers explored the views and knowledge of staff, patients and families/carers relating to EDAR and complex feeding decisions. Formal meta-analysis was not possible due to the level and mix of methodology. Conclusion: There is a paucity of evidence to determine if EDAR protocols improve care. However, support is emerging for a coordinated approach to managing EDAR. Findings suggest having a protocol is not enough; training and communication within teams is essential, together with incorporating feedback from patients and carers, and this justifies further work.

Background: Silent aspiration (SA) is common post‐stroke and associated with increased risk of pneumonia, length of stay and healthcare costs. Clinical swallow examinations (CSEs) are unreliable measures of SA. There is no consensus on the clinical components that best detect SA. Cough reflex testing (CRT) is an alternative/adjunct whose SA detection accuracy also lacks consensus. Aims: To investigate the feasibility of CSE versus CRT against gold standard flexible endoscopic evaluation of swallowing (FEES) for SA identification and to estimate its prevalence in a hyperacute stroke setting. Methods & Procedures: A single‐arm preliminary, prospective, feasibility study of patients less than 72 h post‐stroke, over a 31‐day period on a hyperacute stroke unit: the Royal Victoria Infirmary, Newcastle‐upon‐Tyne, UK. Ethical approval for the study was obtained. The study tested the feasibility and acceptability of introducing CRT and developing a standardized CSE. Consent/assent was obtained for all participants. Patients unfit for study were excluded. Outcomes & Results: A total of 62% of patients less than 72 h post‐stroke (n = 61) were eligible. A total of 75% of those approached (n = 30) consented. A total of 23 patients completed all tests. The principal barrier was anxiety regarding FEES. Mean test time for CRT = 6 min; CSE = 8 min; FEES = 17 min. Patients rated CRT and FEES on average as moderately uncomfortable. A total of 30% (n = 7) of participants who received FEES presented with SA. Conclusions & Implications: CRT, CSE and FEES are feasible in 58% of hyperacute stroke patients in this setting. FEES anxiety is the main recruitment barrier and is not always well tolerated. Results support further work to establish optimum methods and differential sensitivity/specificity of CRT and CSE in hyperacute stroke for SA identification. WHAT THIS PAPER ADDS: What is already known on this subject: SA significantly increases the risk of pneumonia in the early days post‐stroke. CSEs are unreliable for identification of SA risk in this population. CRT is gaining popularity as a potential tool to identify stroke patients at risk of SA, though there are questions regarding the efficacy of the clinical protocol currently being used in the UK. What this study adds to existing knowledge: This study demonstrates that it is practical and feasible to carry out a larger scale study in this setting to compare CSE and CRT including a consideration of an approach combining both methods for clinical identification of SA versus FEES. Preliminary findings suggest that CSE may have higher levels of sensitivity than CRT for SA identification. What are the potential or actual clinical implications of this work?: The results of this study suggest that further work is needed to establish the optimum methods and differential sensitivity/specificity of clinical tools for SA detection in hyperacute stroke.

Background: Perceptual, cognitive and previous clinical experience may influence a novice Videofluoroscopic Swallowing Study (VFSS) analyst's trajectory towards competency. Understanding these factors may allow trainees to be better prepared for VFSS training and may allow training to be developed to accommodate differences between trainees. Aims: This study explored a range of factors previously suggested in the literature as influencing the development of novice analysts' VFSS skills. We hypothesised that knowledge of swallow anatomy and physiology, visual perceptual skills, self‐efficacy and interest, and prior clinical exposure would all influence VFSS novice analysts' skill development. Methods & Procedures: Participants were undergraduate speech pathology students recruited from an Australian university, who had completed the required theoretical units in dysphagia. Data assessing the factors of interest were collected—the participants identified anatomical structures on a still radiographic image, completed a physiology questionnaire, completed subsections of the Developmental Test of Visual Processing—Adults, self‐reported the number of dysphagia cases they managed on placement, and self‐rated their confidence and interest. Data for 64 participants relating to the factors of interest were compared with their ability to accurately identify swallowing impairments following 15 h of VFSS analytical training, using correlation and regression analysis. Outcomes & Results: Success in VFSS analytical training was best predicted by clinical exposure to dysphagia cases and the ability to identify anatomical landmarks on still radiographic images. Conclusions & Implications: Novice analysts vary in the acquisition of beginner‐level VFSS analytical skill. Our findings suggest that speech pathologists who are new to VFSS may benefit from clinical exposure to dysphagia cases, sound foundational knowledge of anatomy relevant to swallowing and the ability to see the anatomical landmarks on still radiographic images. Further research is required to equip VFSS trainers and trainees for training, to understand differences between learners during skill development. WHAT THIS PAPER ADDS: What is already known on the subject: The existing literature suggests that no vice Video fluoroscopic Swallowing Study (VFSS) analysts training may be influenced by their personal characteristics and experience. What this study adds: This study found that student clinicians, clinical exposure to dysphagia cases and their ability to identify anatomical landmarks relevant to swallowing on still radiographic images prior to training best predicted their ability to identify swallowing impairments after training. What are the clinical implications of this work?: Given the expense of training health professionals, further research is required into the factors that successfully prepare clinicians for VFSS training, including clinical exposure, foundational knowledge of anatomy relevant to swallowing and the ability to identify the anatomical landmarks on still radiographic images.

Background: Post‐COVID Syndrome (also known as Long COVID) refers to the multi‐system condition affecting individuals following COVID‐19 infection. This can include speech and language therapy (SLT) needs, including voice, swallowing, communication and upper airway difficulties. There is limited published literature in this clinical area of practice, particularly for those receiving input from community SLT services. Aims: To describe and compare demand, typical SLT presentation and service delivery across two National Health Service (NHS) Long COVID multidisciplinary services. Independent retrospective service evaluation was completed for each service. Descriptive statistics were produced and compared across services. This service evaluation followed The Strengthening the Reporting of Observation Studies in Epidemiology guidelines for cohort studies. Outcomes & Results: The findings indicated similarities across the two services in SLT service need and demand, clinical presentations and intervention approaches provided within Long COVID services. There were specific differences in the service provision and delivery of intervention in cognitive communication and upper airways subspecialities. Conclusions & Implications: This study highlights the clinical complexities of SLT needs in individuals with Long COVID and the importance for an appropriately skilled and supported workforce within effective multidisciplinary teams. We call for consensus on SLT practices and a consistent and standardized approach to evaluation for SLT needs in Long COVID. WHAT THIS PAPER ADDS: What is already known on this subject: SLT needs, including voice, swallowing, communication and upper airway difficulties, are present in individuals presenting with Long COVID, both in those who were or were not hospitalized. SLTs are seeing such individuals in a variety of settings, including community services and Long COVID multidisciplinary teams. There is minimal evidence of the clinical presentations and interventions provided to individuals with SLT needs compared across Long COVID services. What this study adds to existing knowledge: This study compares two NHS Long COVID services providing a SLT service pathway. It highlights the similarities and differences in service demand and capacity, patient presentation, and SLT intervention to make suggestions for future practice consideration and priority evaluation. Expert consensus among SLT clinicians is a priority to ensure clinicians are delivering consistent and equitable care for patients, while new evidence and data emerge. A consistent and standardized approach to data collection and outcome measures is essential to ensure future research captures the impact and value of SLT input with individuals with Long COVID. What are the clinical implications of this work?: The complexities and multifactorial SLT needs of individual with Long COVID call for appropriate SLT staffing provision, skill and training to fulfil the needs of this population. Speech and language therapists should be integrated with multidisciplinary Long COVID services to provide holistic care for patients and to support the professionals working with individuals with post‐COVID voice, swallowing, communication and upper airway symptoms.

Background: Dysphagia is a common complication in patients with stroke. Although the research on acupuncture treatment of dysphagia has stepped up, the results are still inconsistent. In this review, we intend to answer the potential of acupuncture in treating dysphagia in stroke patients and which acupuncture points are the most promising for treating dysphagia. Methods: We used PRISMA (the preferred reporting items for systematic reviews and meta-analysis) 2020 guidelines in conducting this review. A literature search was performed in four databases (PubMed, ScienceDirect, Cochrane, and Willey online library) to find eligible randomized controlled studies that assessed the effect of acupuncture in post-stroke dysphagia. The search time is from 2010 to 2022. Study quality was assessed using the critical appraisal skills program (CASP), and the risk of bias was evaluated by the RoB software, version 2 (risk-of-bias tool). The data were analyzed thematically. Results: A systematic electronic search identified 1409 publications through forward and backward searching of relevant papers. The full-text screening was conducted on 777 articles. A total of 681 articles failed to meet eligibility criteria at this stage, and only 6 articles were finally eligible for further analysis. The results showed that compared with rehabilitation, acupuncture significantly improved dysphagia in post-stroke patients. Gallbladder (GB) 20 is often used as an acupoint. In addition, the frequency and duration of treatment also contributed to a more significant increase in dysphagia improvement. Conclusion: Acupuncture could effectively improve dysphagia in post-stroke patients, and acupuncture combined with rehabilitation has a better effect. [ABSTRACT FROM AUTHOR]

Background: Cervical auscultation has been used clinically as an augmentative procedure for swallow examination. Despite its frequent use for screening and preliminary assessment of swallowing, the usefulness of cervical auscultation is controversial due to a lack of sufficient research, particularly in quantifying swallowing sounds. Aims: To document the acoustic characteristics of normal swallowing sound associated with swallowing bolus of different consistencies among younger healthy adults. Methods & Procedures: A total of 30 healthy young adult participants swallowed 5 ml thickened liquids of four different consistencies (slightly thick, mildly thick, moderately thick and extremely thick) prepared using a starch‐based commercial thickener, and the corresponding swallowing sounds were recorded using a wireless accelerometric stethoscope. An array of acoustic measures including duration of swallowing sound (DSS), duration to peak intensity (DPI), frequency at peak intensity (FPI), peak intensity (PI), average intensity (AI), and difference between peak and average intensity (DPAI) values associated with the swallowing signals were obtained. Outcomes & Results: In general, increased durational measures of the swallowing sounds were associated with an increase in bolus consistency. Intensity measures including PI, AI and DPAI were found to be stable across different consistencies. The change in FPI did not appear to be particularly meaningful due to its high variability. In addition, no significant differences were observed between men and women. Conclusions & Implications: Swallow sounds associated with different bolus consistencies could be quantified and used to differentiate consistencies. The present findings could serve as a reference for future swallowing research of normal and dysphagic population. WHAT THIS PAPER ADDS: What is already known on the subject: Cervical auscultation using traditional stethoscope has been used as part of an informal clinical swallow examination by practitioners. Validity of cervical auscultation is controversial, possibly due to the lack of normative data on swallow sounds. What this paper adds to existing knowledge: The present study explored the possibility of using wireless accelerometric stethoscopy for cervical auscultation for dysphagia screening. Acoustic profiles of swallow sounds associated with boluses of different consistencies in healthy individuals were examined. What are the potential or actual clinical implications of this work?: Findings contribute to our knowledge about the acoustic characteristics of swallow sounds of boluses of different consistencies in healthy young individuals. The study provides normative clinical data on cervical auscultation using wireless accelerometric stethoscope for normal swallow. [ABSTRACT FROM AUTHOR]

Background: The use of ultrasound as an adjunct to clinical swallowing evaluation provides quantitative physiological and morphological data. As a low‐risk procedure, ultrasound imaging can be performed outside of a medical setting. This is particularly important for patients living in rural areas with restricted access to a hospital. Technical advances have produced pocket‐sized ultrasound technology that is more affordable, and therefore within the fiscal reach of most allied health services. Aims: To explore the validity and reliability of pocket‐sized ultrasound technology in dysphagia assessment. Methods & Procedures: Data were acquired from 43 patients with dysphagia using the Clarius ultrasound device. Ultrasound and videofluoroscopic measures of hyoid and laryngeal displacement during liquid and puree swallowing were collected concurrently to quantify correlation and agreement between identical measures derived from the two instruments. Reliability of ultrasound was assessed for measures of hyoid and laryngeal displacement, tongue thickness, and size of the submental muscles in eight patients. Reliability was evaluated for the entire process of data acquisition including scanning and online measurement using an iPad in a clinical setting and for offline measurement on a computer screen to explore environmental influences on reliability. Outcomes & Results: Results revealed poor correlation between the measures of interest across instruments. Reliability of the entire process of data acquisition in a clinical setting was insufficient while reliability was more promising for offline measurements. Conclusions & Implications: The clinical use of pocket‐sized ultrasound devices, such as the Clarius system, for swallowing evaluation is not indicated at this time. Enhanced validity and reliability of the entire process of data acquisition are needed prior to clinical translation of such technology. WHAT THIS PAPER ADDS: What is already known on the subject: The use of ultrasound allows for radiation‐free, non‐invasive swallowing assessment. Some data suggest that ultrasound is valid and reliable in the evaluation of swallowing using standard‐sized equipment. Insufficient validity and reliability have been reported for pocket‐sized ultrasound technology in the assessment of healthy swallowing. What this paper adds to existing knowledge: This research is the first to provide validity and reliability data of the pocket‐sized Clarius technology in the evaluation of swallowing in patients with dysphagia. Insufficient validity and reliability of online data acquisition in a clinical environment were found. Reliability for offline measurement was more promising. What are the potential or actual clinical implications of this work?: The clinical use of pocket‐sized ultrasound devices, such as the Clarius system, for swallowing assessment is not indicated at this time.

Background: Digital cervical auscultation (CA) has been proposed since the 1950s for screening aspiration among patients with dysphagia. Researchers have investigated the 'external' effects such as bolus viscosity, volume, and head and neck positions. However, the influences of standardized liquid viscosity and food texture on swallowing sounds have not been fully understood due to lacking uniform standardization of bolus preparation. Furthermore, a paucity of the literature recommends proper viscous liquids and foods to start swallowing training or monitor the swallowing progress during the continuum of disease based on acoustic signals. Aims: To investigate the effects of eight‐level liquids and foods on swallowing sound features based on the International Dysphagia Diet Standardisation Initiative (IDDSI). Methods & Procedures: We collected swallowing sounds from 30 healthy participants ranging in age from 19 to 60 years and who were self‐reporting no history of swallowing disorders. Each participant swallowed liquids and foods regarding different consistency or texture with their head–trunk in a neutral position. Outcomes & Results: Features of swallowing acoustic signals and the IDDSI flow test as well as food test confirmed the level 3 moderately thick (MO3) was more suitable to categorize into liquids and the level 4 extremely thick (EX4) was more corresponded to the properties of food bolus. We found significant differences in duration of acoustic signals across different liquids and foods except between swallowing level 0 thin liquid and level 1 slightly thick liquid, as well as EX4 and level 5 minced and moist. Our results also demonstrated liquid viscosity significantly impacted the peak intensity of swallowing sounds. Conclusions & Implications: As an initial exploration of digital CA across eight levels of different liquids and foods according to the IDDSI, we established the baseline findings for future comparisons with other study populations or other various consistent liquids/foods. Although both MO3 and EX4 can be considered as liquid or food boluses with high thickness, MO3 might be suitable as the 'start liquid' for patients with dysphagia; however, the decision still needs to be confirmed by the healthcare provider based on patients' safety and the area of deficit. We also concluded there are influences of varied fluid consistency and food texture on swallowing sounds. Furthermore, future investigations should explore whether changing viscosity levels could either continuously or discretely disturb the swallowing acoustic signals. What this paper adds: What is already known on the subject: Previous studies have found that the 'external' effects such as bolus viscosity, volume, and head and neck positions. Due to lacking uniform standardization of bolus preparation, there is limited information about the influences of standardized liquid viscosity and food texture on swallowing sounds. What this paper adds to the existing knowledge: As an initial exploration, we utilized digital CA with a large sample of viscous liquids and different textures of foods based on the IDDSI to investigate the swallowing sounds. What are the potential or actual clinical implications of this work?: This study confirms that the effects of various fluid consistency and food texture on swallowing acoustic signals. However, the findings of this study support the need for further research relating to changing viscosity could either continuously or discretely disturb the swallowing acoustic signals.

Tracheostomy and dysphagia are independently associated with increased complications and poorer functional outcome after acquired brain injury (ABI). The aim of this study was to identify and evaluate rehabilitation to restore functional swallowing ability and respiratory capacity during tracheal tube weaning. The review was conducted according to PRISMA guidelines. Any study design with adult patients with ABI and tracheostomy was eligible. The primary outcome was decannulation. A total of 2647 records were identified and eight papers included. Four studies investigated pharyngeal electrical stimulation (PES), two explored Facial Oral Tract Therapy (F.O.T.T.), one respiratory physiotherapy (RPT), and one study investigated external subglottic air flow (ESAF). Two RCTs found a significant difference between intervention and control on successful decannulation and readiness for decannulation in favour of PES. Time from rehabilitation admission and tracheostomy to decannulation was significantly reduced after implementing an F.O.T.T.-based protocol. Four interventions were identified, PES, F.O.T.T., RPT, and ESAF, all aimed at increasing oropharyngeal sensory input through stimulation. Due to heterogeneity of interventions, designs and outcome measures, effect could not be estimated. This review highlights the limited research on rehabilitative interventions and thus the limited evidence to guide clinical rehabilitation. Rehabilitation for early decannulation after brain injury Dysphagia and tracheostomy often coexist in neurocritical care and early rehabilitation. Four rehabilitative interventions were identified—pharyngeal electrical stimulation, external subglottic airflow, respiratory physiotherapy and facial-oral tract therapy. Interventions points to a consensus that sensory stimulation of the oropharynx can increase excitability of the swallowing network and support pharyngeal sensorimotor cortex reorganisation. This review highlights the limited research on therapeutic rehabilitative interventions and thus the limited evidence to guide clinical rehabilitation. [ABSTRACT FROM AUTHOR]

- Abstract
Timely and complete laryngeal closure is critical for a successful swallow. Researchers have studied laryngeal closure, including true vocal cords (TVC) closure, closure of the arytenoids to the epiglottis base (laryngeal vestibule closure), and epiglottic inversion, but the most commonly available imaging tools have limitations that do not allow the study of these components individually. Swallowing computerized tomography (CT) has enabled three-dimensional dynamic visualization and quantitative evaluation of swallowing events providing a unique view of swallowing-related structures and their motion. Using CT, TVC closure can be visualized and evaluated on any plane or cross-section without being obscured by of laryngeal vestibule closure or epiglottis inversion. The current review summarizes the results of five papers evaluating the effects of bolus consistency and volume, posture, and age on TVC closure. The combined results of these studies suggest that TVC closure is responsive to oral sensory input based on bolus consistency and size and can be modulated in response to conditions perceived to increase the risk of airway invasion. These results are meaningful for dysphagia rehabilitation as it suggests that interventions to improve TVC closure are likely to enhance airway protection. [ABSTRACT FROM AUTHOR]

Background: Above cuff vocalisation (ACV) involves the application of an external flow of air via the subglottic port of a tracheostomy. ACV can facilitate vocalisation and may improve swallowing and quality of life for patients with a tracheostomy. A recent systematic review highlighted the limited evidence available for the acceptability, effectiveness, safety or optimal implementation of ACV. Aims: To explore the experience of healthcare professionals (HCPs) using ACV and their perceptions of best practice. Methods and Procedures: Semi‐structured interviews were conducted with a range of HCPs with experience using ACV. Topics included: experiences with ACV, management of ACV, opinions about ACV, impact of COVID‐19, future directions for ACV and impact on length of stay. Interviews were conducted online from December 2020 to March 2022. Data were analysed using reflexive thematic analysis. Outcomes and Results: Twenty‐four HCPs were interviewed from seven countries and five professional groups. Four interconnected themes were developed: (1) moral distress amplifying the need to fix patients; (2) subjectivity and uncertainty leading to variations in practice and purpose; (3) knowledge and experience leading to control and caution; and (4) worth a try or a last resort. Theme four contained three sub‐themes: (a) part of the toolbox; (b) useful but limited tool; and (c) following the patient's lead. The moral distress experienced by HCPs and their essential 'need to fix' patients seems to underpin the varied opinions of ACV. These opinions appear to be formed primarily on the basis of experience, because of the underlying subjectivities and uncertainties. As knowledge and experience with ACV increased, and adverse events were experienced, most HCPs became more cautious in their approach to ACV. Conclusions and Implications: More research is needed to reduce the subjectivities and uncertainties surrounding ACV. The implementation of standardised procedures, processes, and competencies may help to reduce the frequency of adverse events and support a more controlled approach. Widening the focus of the purpose of ACV to include swallowing may help to maximise the potential benefits. WHAT THIS PAPER ADDS: What is already known on the subject: There is limited and low‐quality evidence for above cuff vocalisation (ACV) and clinical application and practice varies substantially. However, the reasons for this variation in practice and healthcare professionals' (HCPs') opinions of ACV were unclear. What this study adds: HCPs' experiences and opinions of ACV vary as a result of the uncertainty and subjectivity surrounding ACV compounded by their personal experiences with it. A need for caution also appears to emerge as HCPs become more familiar and experienced with using ACV. What are the clinical implications of this work?: Implementing standardised procedures, safety processes and competencies may help to compensate for the uncertainty and subjectivity surrounding ACV and may reduce the frequency of adverse events. Widening the focus of purpose of ACV, including swallowing in addition to communication, may increase the number of potential candidates and increase the potential benefits of ACV. Using multidisciplinary team (MDT) simulation training for ACV competency development might help to improve MDT working and ACV implementation. [ABSTRACT FROM AUTHOR]

Background: Person‐centred services are inherently related to patients/caregivers' needs. However, the extent to which dysphagia services within Singapore meet consumer needs is largely unknown. Involving patients/caregivers in service evaluation/redesign deepens the understanding of consumer needs. This process also increases the success of implementing service enhancements through relevant and meaningful change. Aim: This study aimed to identify aspects of dysphagia services, within acute and subacute settings in Singapore, perceived as highly important and easy to change by patients/caregivers. Methods & Procedures: Using concept mapping methodology, 5 patients and 11 caregivers reflected on their experiences of receiving dysphagia care and proposed 59 unique suggestions to improve dysphagia services within Singapore. Then, each individual sorted the suggestions into groups based on similarity and rated each statement for its perceived importance and changeability for service enhancement. Data were analysed using multidimensional scaling, hierarchical cluster analysis, and bivariate analysis to generate clusters of conceptually similar suggestions and a prioritised list of suggestions for service enhancement. Results: Twelve clusters were identified, with most rated as more important than changeable for service improvement. Participants prioritised 23 (39%) of the suggestions as highly important and easy to change, and these focused on ensuring effective communication among consumers and healthcare team, enhancing patients and carers' access to support at home, increasing patients and carers' access to educational resources, and improving service quality and access through technology. Conclusion: These findings provide future directions on how to develop and implement dysphagia services in Singapore to better meet the needs of patients/caregivers. WHAT THIS PAPER ADDS: What is already known on this subject: Little is known about patients and caregivers' experiences and expectations of receiving dysphagia services in Singapore. Consulting them in service review and improvement deepens understanding of their needs and increases the success of implementing meaningful service enhancements. What this study adds to existing knowledge: This study shows that patients and caregivers in Singapore identified a wide range of dysphagia service issues and prioritised a list of suggestions for service improvement. They prioritised four key areas for service optimisation: ensuring effective communication among consumers and healthcare team, enhancing patients and carers' access to support at home, increasing patients and carers' access to educational resources, and improving service quality and access through technology. What are the clinical implications of this work?: This research highlights the importance of considering the consumers' perspectives in service review and redesign. Patients and caregivers in Singapore identified four prioritised areas for service enhancements. These findings provide future directions on how to develop and implement dysphagia services in Singapore to better meet the needs of patients and caregivers. [ABSTRACT FROM AUTHOR]

Introduction: Three adult case reports (79 and 60 years old females and a 60 year old male) were selected to demonstrate maxillary morphogenesis. These patients were treated for maxillary underdevelopment which can affect occlusion and airway space due to the relationship between the tongue and the hard palate. Intervention: Each patient wore the Homeoblock™ appliance for a minimum of twelve months. The Homeoblock™ consists of 'Adams clasps' on the bicuspids with a baseplate that incorporates a palatal expansion jack screw. The appliance is relieved from the palatal tissues. Flap springs rest on the anterior teeth and a Hawley arch wire extends from left to right canine. A bite block is placed on the second bicuspid and first molar on the less developed side. Results: Improved tongue position, tone, and the resulting increased pharyngeal airway size were found with each patient. Discussion: Once nurture seemed clearly distinct from nature. External influences seem to be able to influence a network of chemical switches within our cells collectively known as the epigenome. Conclusion: These three cases demonstrated how modifications of tissues in the craniofacial region can occur with adult patients in their 6th and 7th decade of life. [ABSTRACT FROM AUTHOR]

- Abstract
To determine the global prevalence of oropharyngeal dysphagia (OD) in adults. Six electronic databases (Embase, LILACS, LIVIVO, PubMed/Medline, Scopus, and Web of Science) were searched, in addition to gray literature (ASHA, Google Scholar, ProQuest Dissertation, and Theses). A random-effects model for meta-analysis of proportions was conducted, and heterogeneity was evaluated according to the moderator variable through subgroup analysis and meta-regression. The risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist and the certainty of the evidence was assessed using the GRADE tool. Thirty papers were included for qualitative and quantitative synthesis. The combined prevalence estimate was 60% [CI 95% = 50%–70%; I
2 = 95%], accounting for different baseline conditions. However, the wide variation that exists between the different baseline conditions (underlying disease or risk factor) tended to overestimate this prevalence when considering the general population. Only one study evaluated healthy individuals, which showed a prevalence of 31% [CI95% = 27%–36%]. The risk of bias was considered low for all studies. None of the variables were considered predictors for the observed variance between the effect sizes of the included studies. For the prevalence of OD, the GRADE rating was considered very low. Despite the high prevalence observed, with over half of the individuals affected, the evidence regarding this outcome remains uncertain due to an overestimation of the generated estimates caused by the baseline condition of the sample.

Background: Studies suggest swallow intervention programmes that incorporate visual biofeedback and motor programming principles can improve swallowing and quality of life for people with idiopathic Parkinson's disease (IPD) and dysphagia. Few studies have examined outcomes using instrumentation. Aims: Using fibreoptic endoscopic examination of swallowing (FEES), this study examines the effectiveness of a neurorehabilitation intervention involving biofeedback via surface electromyography (sEMG) to improve swallowing in people with IPD, and to explore the feasibility of the intervention approach. Methods & Procedures: We recruited 12 participants with IPD and dysphagia. A total of 10 completed the study. Intervention was delivered for 1 h per day, 5 days per week, for 4 weeks (20 h). Swallowing tasks using sEMG biofeedback incorporated principles of motor learning and neuroplasticity. Instrumental and non‐instrumental assessment, including quality‐of‐life measures carried out at four different time points (two pre‐treatment and two post‐treatment). The final assessment was at 3 months post‐intervention. Outcome & Results: Statistically significant improvement (p < 0.05) in oral intake methods (95% confidence interval (CI) = 4.70–5.50) and in pharyngeal residue from saliva (95% CI = 2.14–3.15) and solids (95% CI = 2.4–3.5) post‐intervention were confirmed using FEES with improvements at 3 months. The intervention protocol was well tolerated. Participants reported positive change in saliva control and duration of mealtimes as well as unanticipated improvements in voice and cognitive attention. Conclusions & Implications: An intensive neurorehabilitation with biofeedback shows positive effects in improving swallow function in IPD. This protocol is feasible with amendments to inform a larger clinical trial. What this paper adds: What is already known on the subject: Biofeedback has positive effects on increasing swallowing function and quality of life in people with IPD and dysphagia. sEMG is the most common method used to deliver swallowing biofeedback in this population. The quality of the evidence on the intervention, based on findings from a recent systematic review, is low. Included studies in this review were heterogeneous in terms of type and frequency of biofeedback, study design and outcome measures. The majority of outcome measures were subjective and higher quality studies to examine the efficacy of biofeedback using sEMG are needed. What this study adds: Recognizing the limitations of earlier studies, this within‐subject feasibility study examined the efficacy and effectiveness of an intensive biofeedback intervention using sEMG in a sample of people with dysphagia and IPD. Valid and reliable outcome measures were used and repeated after a 3‐month period. The feasibility of the methodological approach was also tested and a qualitative component was included in the study. Positive findings were evident. Qualitative information added new perspectives and provided direction for new outcomes to be included in future studies. This study helps to inform further research trials as well as clinical practice. Clinical implications of this study: This intensive intervention using principles of neuroplasticity and motor programming with sEMG biofeedback led not only to positive swallowing outcomes but also to unexpected benefits such as improved voice production and general attention skills. No adverse events were reported. Improvement in function was retained at 3 months post‐intervention. Despite the small sample size, participants described the benefits of the treatment, and enjoyed sEMG biofeedback tasks, especially using an sEMG game mode. This suggests that intensive biofeedback not only improved swallowing but also was acceptable to these participants. This intensive protocol has merit and is worth considering further in clinical practice. [ABSTRACT FROM AUTHOR]

Summary: The brain tumor classification is implemented through biopsy, which is not normally executed before classic mind surgery. Machine learning (ML) algorithms assist radiologists in tumor analysis, not including obtrusive evaluations. The conventional ML strategies need separate feature extraction to tumor detect thus it needs more computation time to perform classification. Deep learning (DL) based convolution neural networks (CNNs) have been focused on brain tumor detection. In this paper, the CNN algorithm is improved based on meta‐heuristics, which are used for pre‐trained systems for databases to categorize MRI brain tumor images. Pre‐trained DL, binary swallow swarm optimization (BSSO) is used for improving the weight and predispositions of the CNN algorithm. It is a block‐wise calibrating system which is dependent on transfer learning. The current technique is assessed over a publically accessible magnetic resonance imaging (MRI) brain tumor database containing three categories as glioma, meningioma, and pituitary by the most noteworthy rate among everyone brain tumor in medical training. The proposed strategy is assessed over T1‐weighted contrast‐enhanced MRI (CE‐MRI) benchmark data. To assess the execution, utilize the proposed strategies to the CE‐MRI dataset for tumor detection and in the general execution of the BSSO‐CNN model is estimated using the execution assessment measurements such as precision, sensitivity (recall), specificity, F1‐score, and accuracy. Exploratory outcomes demonstrated with the purpose of the proposed strategy higher when compared to other methods to all metrics. [ABSTRACT FROM AUTHOR]

In this paper, we propose six methods for binarization of the swallow swarm optimization (SSO) algorithm to solve the feature selection problem. The relevance of the selected feature subsets is estimated by two classifiers: a fuzzy rule-based classifier and a classifier based on k-nearest neighbors. To find an optimal subset of features, we take into account the number of features and classification accuracy. The developed algorithms are tested on datasets from the KEEL repository. For the statistical evaluation of the binarization methods, we use Friedman's two-way analysis of variance by ranks for related samples. The best feature selection result is shown by a hybrid method based on modified algebraic operations and MERGE operation introduced by the authors of this paper. The best classification accuracy is achieved with a V-shaped transfer function. [ABSTRACT FROM AUTHOR]

Background: Dysphagia is a highly prevalent condition and affects a wide range of cohorts. A common compensatory strategy to manage dysphagia is diet modification. However, this technique is often associated with poor patient quality of life and adverse long‐term effects. Carbonated liquids have shown promise as an alternative compensatory strategy for the management of dysphagia. Aims: To examine the effect of genetic taste status and intensity of carbonation on swallowing and palatability in a healthy young adult population. To examine the palatability of carbonated liquids over time. Methods & Procedures: A total of 35 healthy young adults were recruited for this prospective, quantitative cohort study. They each drank 150 ml of still water (SW), lightly carbonated water (LCW) and highly carbonated water (HCW). Swallow function, palatability and genetic taste status were assessed using the timed water swallow test, the hedonic general labelled magnitude scale and participant ratings of the bitterness of propylthiouracil strips, respectively. Participants were divided into groups of supertasters, moderate tasters and non‐tasters. Outcomes & Results: A significant difference was found between SW and HCW on three tests of swallow function. Average time per swallow increased (p = 0.03), average swallow velocity decreased (p = 0.001) and average volume per swallow decreased (p = 0.017) on HCW compared with SW. HCW had a greater impact on swallow function than LCW. A significant mean difference in palatability ratings was found across intensity levels of carbonated fluids (p = 0.002), specifically between SW and HCW (p = 0.001). HCW was less palatable than SW. The palatability of carbonated liquids, investigated within a subgroup of five participants, did not decrease after a 24‐h period during which participants only drank carbonated liquids (p = 0.102). A significant difference was found between supertasters' (n = 9) (mean = 13.33) and non‐tasters' (n = 20) (mean = –24.5) palatability ratings of HCW (p = 0.03). Despite differences in swallow function between SW and HCW, no differences were detected between supertasters' and non‐tasters' swallow function on SW, LCW or HCW. Conclusions & Implications: Carbonated liquids have the ability to alter swallow function in a healthy young adult population; however, liquids must be highly carbonated in order to have an effect. Additionally, highly carbonated liquids are less palatable than SW, but the palatability of carbonated liquids does not decrease over time. Furthermore, supertasters find HCW more palatable than non‐tasters. These findings suggest that carbonated liquids alter swallowing in a healthy population. Further research in a clinical population is needed to better understand the potential role of sensory stimulation as a dysphagia intervention. What this paper adds: What is already known on the subject: Several studies have found that carbonated liquids have the ability to alter swallow function in both healthy and clinical populations. However, there is a lack of evidence around the optimum intensity of CO2 in carbonated liquids and the palatability of carbonated liquids as well as the palatability of carbonated fluids over time. What this paper adds to existing knowledge: The findings from this study suggest that carbonated liquids can alter swallow function in a healthy young adult population, but liquids must be highly carbonated in order to have an effect. HCW is less palatable than SW, but the palatability of carbonated liquids does not decrease over time. Additionally, supertasters find HCW more palatable than non‐supertasters (non‐tasters). What are the potential or actual clinical implications of this work?: The findings from this study suggest that carbonated liquids may be suitable for use as a sensory stimulation technique for people with dysphagia, as their palatability does not decrease over time; however, further research in a clinical population is needed in order to determine this. Additionally, intensity of stimulus is an important factor to consider during dysphagia evaluation to identify what intensity is required to optimize swallowing. [ABSTRACT FROM AUTHOR]

- Abstract
Dysphagia results from diverse and distinct etiologies. The pathway from anatomy and physiology to clinical diagnosis is complex and hierarchical. Our approach in this paper is to show the linkages from the underlying anatomy and physiology to the clinical presentation. In particular, the terms performance, function, behavior, and physiology are often used interchangeably, which we argue is an obstacle to clear discussion of mechanism of pathophysiology. We use examples from pediatric populations to highlight the importance of understanding anatomy and physiology to inform clinical practice. We first discuss the importance of understanding anatomy in the context of physiology and performance. We then use preterm infants and swallow-breathe coordination as examples to explicate the hierarchical nature of physiology and its impact on performance. We also highlight where the holes in our knowledge lie, with the ultimate endpoint of providing a framework that could enhance our ability to design interventions to help patients. Clarifying these terms, and the roles they play in the biology of dysphagia will help both the researchers studying the problems as well as the clinicians applying the results of those studies.

Sepsis is a major global health problem with an estimated 49 million cases globally each year causing as many as 11 million deaths. The primary objective of this commentary is to describe the impacts of sepsis and critical illness on communication and swallowing function, and to discuss management strategies considering the Sustainable Development Goals (SDGs). Communication and swallowing disabilities can occur with sepsis and critical illness. A holistic framework to optimise function, recovery, and future research priorities across the lifespan can be developed through the SDGs. Communication and swallowing disabilities following critical illness associated with sepsis have global impacts. Early multidisciplinary engagement is key to optimising individuals' function. Collaborative research, education, and public awareness is urgently needed to increase equity in health outcomes across populations. This commentary paper supports progress towards good health and well-being (SDG 3), quality education (SDG 4) and reduced inequalities (SDG 10). [ABSTRACT FROM AUTHOR]

Background: Quantitative measures can increase precision in describing swallowing function, improve interrater and test–retest reliability, and advance clinical decision‐making. The Test of Mastication and Swallowing Solids (TOMASS) and the Timed Water Swallow Test (TWST) are functional tests for swallowing that provide quantitative results. Aims: To explore the relationship between TOMASS and TWST; evaluate test–retest and interrater reliability; explore age and gender effects; and gather normative data. Methods & Procedures: Healthy community dwelling participants (n = 298, ≥ 20 years old) were recruited. Of those, 126 were included in the reliability study. Participants completed the TWST and TOMASS. Outcomes & Results: Associations between TWST and TOMASS measures were found using Pearson's correlation coefficient. Age was positively associated with an increase in the number of bites (n = 292, r = 0.15, p = 0.009), masticatory cycles (n = 291, r = 0.33, p < 0.0001) and duration (n = 292, r = 0.32, p < 0.0001) for the TOMASS. For the TWST, age was positively associated with an increase in duration (n = 296, r = 0.23, p < 0.0001), and negatively associated with volume (n = 296, r = −0.205, p < 0.0001), and swallowing capacity (n = 296, r = −0.24, p < 0.0001). Females required more bites, masticatory cycles, swallows and longer time than males in TOMASS. In TWST, females required more swallows, longer time, and had lower volume per swallow and reduced swallowing capacity than males. Intraclass correlation coefficient (ICC) revealed good test–retest reliability and moderate to excellent interrater reliability. Conclusions & Implications: This study provides support for the validity of the TOMASS and TWST. Reduced efficiency in one of the tests might indicate a need to evaluate performance in the other. Extended chewing time and increased number of masticatory cycles might be compensatory behaviours for reduced oral processing abilities that are motor, sensory and/or mechanical. WHAT THIS PAPER ADDS: The TOMASS and TWST are functional tests of swallowing that provide quantitative results. They are easy to incorporate as part of the clinical evaluation of swallowing due to low cost and quick administration. Age and gender effects were found for the TWST and TOMASS, but they were only tested on relative measures rather than absolute measures. Different types of crackers used for TOMASS led to differences in performance and in normative values. What is already known on the subject: Associations between performance during TWST and TOMASS were found: time, number of swallows and time per swallow were correlated, meaning that need for more time and more swallows is reflected in both drinking and chewing. The study provides further support for age and gender effects in TWST and TOMASS, on both relative and also on absolute measures, which were not investigated previously. Longer durations in TOMASS and TWST with an increase in age, are likely to be the result of compensatory behaviours to allow safe swallowing. Normative data for a country‐specific cracker are presented (Israel). What are the potential or actual clinical implications of this work?: Reduced efficiency in one of the tests might indicate a need to evaluate performance in the other. Establishing country specific norms for commonly available crackers is necessary, since crackers size and ingredients, such as fat content and moisture, influence chewing and swallowing. There is a balancing act between safety and efficiency in older adults' swallowing behaviour. Reducing pace in eating and drinking probably supports safer swallowing. [ABSTRACT FROM AUTHOR]

Purpose: The objectives of this scoping review were to summarize, understand, and disseminate findings from a broad body of literature on rehabilitation interventions used with survivors of head and neck cancer. Method: Searches were conducted in six databases. Inclusion criteria were studies of adult head and neck cancer survivors with a predefined primary rehabilitation outcome as a result of an intervention. Excluded were studies not written in English, opinion papers, or studies where the intervention was not carried out by a rehabilitation healthcare service. A second level, full-text review of the studies was conducted. A thematic analysis was used to examine and combine study findings. Results: A total of 3804 results were retrieved from all sources resulting in 39 papers that were analyzed. The thematic analysis of the included papers represented interventions focusing on swallowing and nutrition, speech, physical therapy, assistive devices, complementary and alternative modalities, comprehensive interdisciplinary programs, and preventive rehabilitation programs. Conclusion: This review has provided an overview of the scope of rehabilitation interventions available for survivors of head and neck cancer and preliminary information about their efficacy. This is foundational information for the development and refinement of rehabilitation interventions and programs for head and neck cancer survivors. The existing evidence suggests that survivors of head and neck cancer can benefit from early screening of potential rehabilitation needs and being involved in preventive rehabilitation programs pre-surgery when possible. Rehabilitation programs should consider swallowing interventions for patients as evidence reports improved swallowing function, decreased pain and discomfort, and reduced duration of feeding tube use. Rehabilitation programs should consider nutritional interventions after radiotherapy: Patients benefited from stabilized weights, improved nutritional status, and an improved quality of life. Physical exercise interventions demonstrated improvements in physical function, muscular endurance, range of motion, overall quality of life, and showed reductions in pain, and fatigue.
