Background: Telehealth for paediatric speech and language therapy became one of the most salient modes of service delivery during the COVID-19 pandemic. Evidence for speech and language therapy services via telehealth in comparison to face-to-face delivery demonstrates promising outcomes, and studies have begun to explore practitioner and client experiences. However, across the literature, many critical elements of services are overlooked, and there is a need to frame the evidence base within a theoretical model that can draw out practical implications that consider the range of factors having an impact on clinical implementation in real-world contexts. The APEASE (Acceptability, Practicability, Effectiveness, Affordability, Side-effects, and Equity) criteria offer such a model. The current study explored practising UK speech and language therapists' (SLTs) clinical experience of telehealth through the lens of the APEASE criteria and aimed to identify recommendations for future service provision from the practitioner perspective., Methods: An online survey structured using the APEASE criteria was developed in collaboration with the UK Royal College of Speech and Language Therapists. Quantitative data were analysed using descriptive statistics and qualitative data were analysed using reflexive thematic analysis., Results: Four hundred and thirty-eight qualified and practicing UK paediatric SLTs completed the survey. Telehealth was broadly acceptable and practicable to SLTs yet there remains some uncertainty about its efficacy and cost-effectiveness compared to face-to-face interventions and how equitable it is for different population groups. SLTs reported that effective implementation of telehealth services was dependent upon several contextual factors; affordability was a perceived barrier to clients having access to telehealth resources, intervention via telehealth was perceived as more acceptable than assessment, and whilst many SLTs welcomed aspects of telehealth, there were concerns about the physical and mental health consequences for practitioners. Six themes for the future development of telehealth in paediatric speech and language therapy were identified: (1) balanced and tailored services; (2) technology and equipment; (3) information and communication; (4) capacity building; (5) monitoring and evaluation; and (6) leadership and governance., Conclusions: Outcomes highlight promising, concerning and uncertain aspects of telehealth in paediatric speech and language therapy. SLTs value a flexible and tailored approach to service delivery and recommend that effective leadership, clear communication, ongoing policy and guidance development, upskilling of users and careful evaluation of impact are required to ensure optimal implementation. The APEASE criteria offer a valuable opportunity to enhance and streamline practice and research to ensure sustainable implementation of telehealth in the paediatric speech and language therapy services of tomorrow., What This Paper Adds: What is already known on this subject The COVID-19 pandemic led to the increased use of telehealth as a main mode of service delivery in paediatric speech and language therapy. Pre-COVID-19, evidence for the use of telehealth in this field included small-scale experimental studies that reported on children with particular disorders and explored telehealth outcomes in comparison to face-to-face delivery. The realities of at-scale clinical practice were not well-represented, and critical elements of service such as cost-effectiveness were often overlooked in the paediatric literature. Furthermore, despite emerging global evidence for temporary telehealth responses to the crisis in speech and language therapy, the long-term and future use of telehealth remains unclear. What this paper adds to existing knowledge The current study applied the lens of the APEASE (Acceptability, Practicability, Effectiveness, Affordability, Side-effects, and Equity) criteria, which were used in this case to consider socioeconomic, ecological and cultural factors to capture an overarching understanding of the use of telehealth in paediatric speech and language therapy, and to inform the role of telehealth in future, longer-term and at-scale service development. Results indicated emerging trends in UK paediatric speech and language therapists' (SLTs') perceptions of telehealth and SLTs perceived a hybrid approach to service delivery, combining mostly face-to-face services with some telehealth, was likely to continue in the future. We identified six themes to guide the future development of telehealth in paediatric speech and language therapy services: (1) balanced and tailored services; (2) technology and equipment; (3) information and communication; (4) capacity building; (5) monitoring and evaluation; and (6) leadership and governance. What are the potential or actual clinical implications of this work? UK SLTs believe that speech and language therapy services using telehealth should be reflective, tailored and flexible to meet the requirements and circumstances of the children, young people and families served, as well as the physical and emotional needs of practitioners. SLTs recommend that this service development is clearly communicated to all stakeholders and suggested that those using telehealth should be supported through appropriate training, and ongoing effectiveness should be monitored. Telehealth is here to stay and the APEASE criteria offer a unique opportunity to ensure sustainable models of service delivery; to support co-ordinated leadership at the local, national and international levels and the development of policy and clinical guidance., (© 2023 The Authors.

Purpose: The neutrophil-to-lymphocyte ratio (NLR) is a relatively novel biomarker to distinguish between acute stresses. This study was performed to determine whether the NLR may discern infectious orbital maladies from idiopathic orbital inflammation (IOI)., Methods: The NLR was calculated by a review of the initial blood draws of adult patients who presented to the emergency department at a single academic medical center. Statistical comparisons were performed to identify the significance of these results., Results: Ten patients with IOI, 12 patients with necrotizing fasciitis (NF), and 12 patients with orbital cellulitis (OC) presented to the emergency department. The groups were not statistically significantly different in terms of age or gender. The mean NLRs were 3.48 (standard deviation = 1.80), 13.5 (standard deviation = 14.5), and 8.15 (standard deviation = 6.56) for IOI, NF, and OC, respectively. Patients with IOI had statistically significantly lower NLRs than patients with NF ( p = 0.037) and OC ( p = 0.034). However, the NLRs of patients with OC were not statistically significantly different from those of patients with NF ( p = 0.27)., Conclusions: The NLR appears to distinguish IOI from infectious etiologies, but does not discern between variants of infection. These results should be juxtaposed against appropriate imaging and clinical evaluations, but elevated NLR values may heighten clinicians' concerns for an infectious process and encourage them to initiate appropriate management steps., Competing Interests: The authors have no financial or conflicts of interest to disclose., (Copyright © 2023 The American Society of Ophthalmic Plastic and Reconstructive Surgery, Inc.)

Purpose: The authors report a technique of local application of anti-metabolite and corticosteroid mixture in the orbit for treatment of thyroid orbitopathy with moderate-severe inflammation and muscle involvement., Methods: Patients of one orbital surgeon seen between March 2019 and May 2020 with active thyroid eye disease and restrictive strabismus were considered for local treatment of the myopathic component of the disease. A mixture of 1 ml 5-FU 50 mg/ml, 0.25 ml triamcinolone 40 mg/ml, and 1 ml lidocaine 2% is injected through the skin using a 25-gauge, 1.5-inch needle into the orbit adjacent to the affected extraocular muscle. Six patients were treated in the outpatient setting and 3 patients have been treated with this intervention intraoperatively at the time of orbital decompression. One was treated with the mixture reconstituted with hyaluronic acid (Healon GV) to address postoperative medial rectus fibrosis to the medial wall, this mixture was applied topically in the operative field and not injected., Results: All patients had subjective improvement in the eye movement limitation and 2 patients had a change in motility on exam that was temporally correlated to injections. One patient did not disclose high-dose aspirin intake before injection and experienced a retrobulbar hemorrhage immediately following injection which was successfully treated. No complications were noted as a result of the medication itself., Discussion: The combination of 5-fluorouracil and triamcinolone acetonide for orbital treatment may be a useful adjunct in treating patients with ongoing inflammatory activity, both in the office and in the operating room. The novel combination may optimize ophthalmic outcomes, modifying disease course in some patients., Competing Interests: The authors have no financial or conflicts of interest to disclose., (Copyright © 2023 The American Society of Ophthalmic Plastic and Reconstructive Surgery, Inc.)

Background: The supraclavicular fossa is the dominant location for human brown adipose tissue (BAT). Activation of BAT promotes non-shivering thermogenesis by utilization of glucose and free fatty acids and has been the focus of pharmacological and non-pharmacological approaches for modulation in order to improve body weight and glucose homeostasis. Sympathetic neural control of supraclavicular BAT has received much attention, but its innervation has not been extensively investigated in humans., Methods: Dissection of the cervical region in human cadavers was performed to find the distribution of sympathetic nerve branches to supraclavicular fat pad. Furthermore, proximal segments of the 4th cervical nerve were evaluated histologically to assess its sympathetic components., Results: Nerve branches terminating in supraclavicular fat pad were identified in all dissections, including those from the 3rd and 4th cervical nerves and from the cervical sympathetic plexus. Histology of the proximal segments of the 4th cervical nerves confirmed tyrosine hydroxylase positive thin nerve fibers in all fascicles with either a scattered or clustered distribution pattern. The scattered pattern was more predominant than the clustered pattern (80% vs. 20%) across cadavers. These sympathetic nerve fibers occupied only 2.48% of the nerve cross sectional area on average., Conclusions: Human sympathetic nerves use multiple pathways to innervate the supraclavicular fat pad. The present finding serves as a framework for future clinical approaches to activate human BAT in the supraclavicular region., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Mori et al.

Purpose: The aim of this study was to map the use of implementation science frameworks, models, and theories in intervention research targeting learning needs in the classroom., Method: A scoping review was conducted. Electronic database and manual searches were conducted. Two reviewers independently completed screening, data extraction, and quality appraisal. Qualitative content analysis was undertaken using Nilsen's taxonomy and the domains of the Consolidated Framework for Implementation Research (CFIR). The data were further analyzed using the CFIR valence and strength rating scales., Results: Included papers ( n = 22) used a diverse sample of implementation science frameworks and models. Most studies used determinant frameworks to guide data collection and analysis. Few studies used implementation science theory. Most studies were mixed methods ( n = 11), published since 2019 ( n = 20), and conducted in North America ( n = 15). Over half of the interventions targeted social, emotional, and mental health ( n = 13). A complex interplay of inner setting factors was identified as having a strong influence on implementation. Teachers' knowledge and beliefs, adaptability, and complexity of interventions were also identified as important considerations when conducting research in this context., Conclusions: Early engagement with stakeholders in education is recommended when designing universal level speech, language, and communication interventions for use in the ordinary classroom. Adaptive, hybrid designs that test both implementation strategies and effectiveness of interventions may be warranted given the influence of inner setting factors on implementation outcomes.

Objective: To evaluate the accuracy of the initial diagnosis in the case of fungal infections of the orbit and identify factors that may influence patient outcomes., Methods: An institutional review board-approved retrospective chart review was conducted across 2 large academic centres to identify cases of fungal infections involving the orbit from January 1, 1998, to November 15, 2019. Data collected included patient demographics, past medical history, examination findings, diagnosis, treatment, imaging, and outcomes., Results: Fifty cases of fungal infection involving the orbit were identified. Of these, 33 (66.0%) were initially misdiagnosed as nonfungal diagnoses. Sixteen patients (32.0%) received multiple initial diagnoses. The most common diagnoses on presentation were bacterial cellulitis (n = 12 of 50; 24.0%) and bacterial sinusitis (n = 12 of 50; 24.0%). These were followed by vascular and orbital inflammatory conditions (n = 9 of 50; 18.0%): 5 patients (10.0%) were clinically diagnosed with giant cell arteritis, 3 (6.0%) with nonspecific orbital inflammation, and 1 (2.0%) with optic neuritis. In this subset of patients, 77.8% (n = 7 of 9) were treated initially with systemic steroids. Additional initial diagnoses included neoplastic mass lesions, mucocele, dacryocystitis, cavernous sinus thrombosis, hemorrhage, tick-borne illness, allergic rhinitis, and allergic conjunctivitis. Misdiagnosis was significantly correlated with involvement of the masticator space on imaging (p = 0.04)., Conclusion: Fungal infections of the orbit are misdiagnosed in 2 of 3 cases. Nearly 15% of patients who are later diagnosed with fungal disease of the orbit were initially treated with systemic steroids. Misdiagnosis is more frequent when the masticator space is involved., (Copyright © 2022 Canadian Ophthalmological Society. Published by Elsevier Inc. All rights reserved.)

Background: Accurate early identification of children with low language ability is important but existing measures generally have low sensitivity. This remains an area of concern for preventive and public health services. This study aimed to create and evaluate a measure of child language, communication and related risks which can be used by community health nurses to accurately identify children with low language aged 24-30 months., Methods: The Early Language Identification Measure (ELIM) was developed and comprised five measurement sections, each measuring different aspects of development combined into a single measure. This was tested blind against a reference standard language measure, the Preschool Language Scale-5 (PLS-5), at the universal 24-30-month health visitor review in England. The threshold for likely low language was the tenth centile or below on the PLS-5. The aim was to ascertain the performance of the five individual sections in the scale, and consider the optimum combination of sections, for predicting low language ability. Specificity, sensitivity, and positive and negative predictive values were reported for each of the five sections of the ELIM alone and in conjunction with each other. The performance for children from monolingual English-speaking families and those who spoke languages other than English were also considered separately., Results: Three hundred and seventy-six children were assessed on both the ELIM identification measure and the PLS-5 with 362 providing complete data. While each section of the ELIM predicted low language ability, the optimal combination for predicting language outcome was the parent reported vocabulary checklist coupled with the practitioner observation of the child's communication and related behaviours. This gave a sensitivity of 0·98 with a specificity of 0·63., Conclusions: A novel measure has been developed which accurately identifies children at risk of low language, allowing clinicians to target resources efficiently and intervene early., (© 2023.

Background: Ten percent of the school-aged population have speech, language, and communication needs (SLCN) that impact access to the curriculum. Successful implementation of classroom-based SLCN interventions can reduce barriers to learning, thereby improving educational outcomes for this vulnerable population. The challenges of implementing innovations in educational settings are well-documented, yet limited studies have addressed such considerations when developing, and piloting universal level SLCN interventions for use in Irish schools., Methods: A qualitative exploratory study was undertaken to establish the acceptability, feasibility, and appropriateness of a universal level SLCN intervention. An advisory panel of teachers (n = 8) and children with SLCN (n = 2) were engaged as co-researchers in the study. The Communication Supporting Classrooms Observation Tool, developed as part of the Better Communication Project in the UK, was trialled across a diverse sample of school settings (n = 5). Semi-structured interviews were conducted with school practitioners and school leaders, and a deductive content analysis was undertaken using the domains of the Consolidation Framework for Implementation Research., Discussion: The observation tool was viewed as acceptable with suggested additions. Integrating use of the tool within existing data-informed, school self-evaluation processes aimed at supporting school improvement was noted as a potential means of supporting implementation. A knowledge gap in relation to school-based models of support for SLCN was identified which may negatively impact implementation. An implementation strategy targeting coherence, cognitive engagement and contextual integration is indicated if the tool is to be normalised into routine practice in Irish classrooms. Implementation needs appeared to vary at the school level., Conclusions: The importance of early-stage exploration to guide implementation planning with regards to developing and testing universal level interventions for SLCN in schools is highlighted. Engaging an advisory panel provides important insights to guide implementation decisions. Findings suggest an adaptive design is required when planning implementation studies targeting classroom setting., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Gallagher et al.

The possible magnetophoretic migration of iron oxide nanoparticles through the cellulosic matrix within a single layer of paper is challenging with its underlying mechanism remained unclear. Even with the recent advancements of theoretical understanding on magnetophoresis, mainly driven by cooperative and hydrodynamics phenomena, the contributions of these two mechanisms on possible penetration of magnetic nanoparticles through cellulosic matrix of paper have yet been proven. Here, by using iron oxide nanoparticles (IONPs), both nanospheres and nanorods, we have investigated the migration kinetics of these nanoparticles through grade 4 Whatman filter paper with a particle retention of 20-25 μm. By performing droplet tracking experiments, the real-time stained area growth of the particle droplet on the filter paper, under the influences of a grade N40 NdFeB magnet, were recorded. Our results show that the spatial and temporal expansion of the IONP stain is biased toward the magnet and such an effect is dependent on (i) particle concentration and (ii) particle shape. The kinetics data were first analyzed by treating it as a radial wicking fluid, and later the IONP distribution within the cellulosic matrix was investigated by optical microscopy. The macroscopic flow front velocities of the stained area ranged from 259 μm/s to 16 040 μm/s. Moreover, the microscopic magnetophoretic velocity of nanorod cluster was also successfully measured as ∼214 μm/s. Findings in this work have indirectly revealed the strong influence of cooperative magnetophoresis and the engineering feasibility of paper-based magnetophoretic technology by taking advantage of magnetoshape anisotropy effect of the particles.

Ablepharon-macrostomia syndrome (AMS) and Barber-Say syndrome (BSS) are congenital ectodermal dysplasias associated with mutations in the TWIST2 gene. Among the ophthalmic anomalies that occur in these syndromes, underdevelopment of the anterior lamella of the eyelid is a defining feature. Reports of mosaic expression of TWIST2 mutations are extremely rare, with only five confirmed or suspected cases described to date. Mosaic expression of TWIST2 variants is correlated with a less severe phenotype than that reported for the typical expression of TWIST2 variants associated with BSS or AMS. Abnormal development of the anterior lamella appears to be a common feature in all cases of AMS with mosaic expression. Here, we describe the phenotype of a patient with mosaic expression of a TWIST2 mutation that is typically associated with AMS. We additionally describe the surgical approach employed in the treatment of this patient.

Purpose: To review the correction of chin-up abnormal head position (AHP) due to infantile nystagmus syndrome via surgery on the vertical rectus muscles, typically a combined recession-resection of these muscles., Methods: This was a review of 6 patients who underwent surgical correction of chin-up vertical AHP in the context of infantile nystagmus syndrome at an academic institution. The correction of AHP, visual acuity, ductions, and ocular alignment were noted both preoperatively and postoperatively. The need for repeat surgery, induced strabismus, or correction of AHP were also noted., Results: Six patients underwent surgery for chin-up AHP. A combined recession-resection of the vertical rectus muscles (bilateral inferior rectus muscle recession of 5 to 8 mm; bilateral superior rectus muscle resection of 7 to 8 mm) was performed in 4 of 6 patients, and isolated bilateral recession of the inferior rectus muscles was performed in the remaining 2 patients. Four of 6 patients (67%) achieved complete correction of their AHP at the last follow-up visit, with a mild residual chin-up AHP persisting in the other 2 patients. One patient developed large angle exotropia, one had restrictive hypertropia and horizontal plane null position, and another developed an incomitant horizontal strabismus with exotropia in right gaze. Reoperation was performed in the former 2 patients, with successful correction of the strabismus in each., Conclusions: Surgery on the vertical rectus muscles can reduce or eliminate a chin-up head position in patients with infantile nystagmus syndrome. Care should be taken to avoid producing a restriction of depression in abduction if the amount of resection is too large. [ J Pediatr Ophthalmol Strabismus . 2022;59(6):410-415.] .

Background: Parental education is one of the best predictors of child school achievement. Higher parental education is not only associated with higher child intelligence, but children from highly educated parents also perform better in school due to other family related factors. This study evaluates the relation between parental education, child non-verbal intelligence and parenting practices with child school achievement., Methods: Longitudinal data from a large population-based, multi-ethnic cohort of children in the Netherlands (63% Dutch origin) followed from birth to age 13 years (3547 children; 52.3% girls) were analyzed. School achievement was measured at the end of primary school (12 years of age) with a national Dutch academic test score. Parental education was assessed at age 3 years. The non-verbal intelligence of the child was measured at age 6 years and a full intelligence was measured at age 13 years. Maternal and paternal family routines, harsh parenting and corporal punishment were assessed in early and mid-childhood. Mediation analysis was performed with the G-formula and Structural Equation Models., Results: Child intelligence partially mediated [B indirect effect =0.54 95% CI (0.46, 0.62) P < 0.001] the association between parental education and child school achievement. Independent of intelligence, family routines [B indirect effect =0.04 95% CI (0.01, 0.07) P < 0.01], but not harsh parenting mediated this association., Conclusions: Higher parental education was associated with better school achievement through two independent mechanisms, through higher intelligence of the child and parenting practices., (© The Author(s) 2022.

A stereoselective synthetic entry point to the 5-8-5 carbocyclic core of the ophiobolins was developed. This strategy exploits the chiral tertiary alcohol of ophiobolin A to guide assmebly of the 5-8-5 scaffold in a single step via a photoinitiated cycloisomerization. Mechanistic insights into the origin of stereocontrol in this reaction are described, as are efforts to elaborate the resultant fused 5-8-5 ring system to the pharmacophore of ophiobolin A.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) decolonization is widely utilized in many medical subspecialities to reduce surgical site infections, but routine ophthalmic implementation has been limited. The aim of this study was to investigate the attitudes and actual practice of corneal specialists and oculoplastic surgeons toward MRSA decolonization as a preventive measure in ophthalmic surgery. Materials and Methods: A web-based survey was sent to cornea specialists and oculoplastic surgeons to assess their knowledge, beliefs, and practices regarding MRSA prophylaxis and the use of MRSA decolonization to prevent post-operative infections. Results: A total of 180 surgeons participated in this study: 71% of respondents agreed that MRSA colonization plays a role in post-operative infection of the eye and adnexal structures; 65% stated that MRSA decolonization could help prevent MRSA infection. Although 41% of respondents would change their management in response to a positive pre-operative MRSA screening result, only 18% performed pre-operative screening. Seventeen percent of respondents indicated that they offer pre-operative decolonization for MRSA-positive patients; the most frequently applied technique was the use of nasal antibiotic agents such as mupirocin, followed by antiseptic baths. Peri-operative MRSA prophylaxis was used by 18% of respondents; pre-operative MRSA decolonization was used in conjunction by 8.5 % of respondents. Conclusions: Although MRSA decolonization has been validated in fields outside of ophthalmology, there has not been widespread adoption of this practice among oculoplastic surgeons and cornea specialists. Prospective MRSA decolonization ophthalmic studies are necessary if evidence-based management guidelines are to be developed.

Children aged 3-4 years ( n = 876) were recruited from deprived areas in England, and a significant minority of the sample were second language learners. Oral language ability was assessed using child administered standardized measures, and parents reported on children's language. We adapted the Language Use Inventory [LUI; (1)] to capture carer's reports of the children's structural language in the language of instruction and their home language (where appropriate). The final measure included six subscales from the original: use of simple words, requests for help, gaining attention, talking about activities/actions, interactions with others, and building sentences. Children's language abilities and non-verbal abilities were below norms on all standardized tests administered except non-word repetition. Factor analysis indicated that all the six scales of the adapted parent completed measure loaded on one language factor. The revised total scale score correlated significantly ( p < 0.0005) with child assessed language measures, specifically expressive vocabulary and grammar. Different patterns across gender, language status and parental education were examined. Sensitivity and specificity of the scale to identify children with the greatest delays were evaluated. These preliminary data indicated that parent-reported information on children's language skills at 3 years of age has the potential to provide a reliable indicator to inform pedagogy and practice at the start of nursery school. Study limitations are examined and avenues for future development explored., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Dockrell, Forrest, Law, Mathers and Charlton.)

A new polyene cyclization strategy exploiting β-ionyl derivatives was developed. Photoinduced deconjugation of the extended π-system within these chromophores unveils a contrathermodynamic polyene that engages in a Heck bicyclization to afford [4.4.1]-propellanes. This cascade improves upon the limited regioselectivity achieved using existing biomimetic tactics and tolerates both electron-rich and electron-deficient (hetero)aryl groups. The utility of this approach was demonstrated with the diverted total synthesis of taxodione and salviasperanol, two isomeric abietane diterpenes that were previously inaccessible along the same synthetic pathway.

Background: Early interventions to support young children's language development through responsive parent-child interaction have proven efficacy but are not currently delivered universally. A potential universal delivery platform is the Health Visitor (HV)-led 2-2½-year-old review in England's Healthy Child Programme. It is unclear if it is feasible to offer such interventions through this platform. We report an intervention development process, including extensive stakeholder consultation and co-design which aimed to develop an acceptable, feasible and equitable early language intervention for delivery in this context., Methods: The study involved five phases including 13 stakeholder co-design workshops with 7 parents and 39 practitioners (HVs, early years practitioners and speech and language therapists): (1) Identification of existing intervention evidence, (2) qualitative review of intervention studies extracting candidate target behaviours for intervention and intervention techniques, (3) co-design workshops with parents and practitioners examining acceptability, barriers and enablers to those behaviours and techniques (particular attention was paid to diverse family circumstances and the range of barriers which might exist), (4) findings were analysed using COM-B and theoretical domains frameworks and a prototype intervention model designed, and (5) co-design workshops iteratively refined the proposed model., Results: Practitioners were committed to offering language intervention at the 2-2½-year-old review but were not sure precisely how to do so. Parents/caregivers wanted to be proactive and to have agency in supporting their own children and to do this as soon as possible. For equitable intervention, it must be proportionate, with higher 'intensity' for higher levels of disadvantage, and tailored, offering differing approaches considering the specific barriers and enablers, assets and challenges in each family. The importance and potential fragility of alliances between parent/caregiver and practitioner were identified as key, and so, strategies to engender successful collaborative partnership are also embedded in intervention design., Conclusion: It is possible to develop a universal intervention which parents and practitioners judge would be acceptable, feasible and equitable for use at the 2-2½-year review to promote children's language development. The result is one of the most explicitly developed universal interventions to promote children's language development. Further development and piloting is required to develop materials to support successful widespread implementation., (© 2022. The Author(s).)

The US Food and Drug Administration (FDA) approval of the biologics license application for the Pfizer-BioNTech coronavirus disease 2019 vaccine (Comirnaty) on August 23, 2021, opened the door to the off-label vaccination of children younger than the age range currently covered by either the biologics license application (16 years old and older) or the emergency use authorization (12 to 15 years old). Although prescribing medications at doses, for conditions, or in populations other than those approved by the FDA is generally legal and is common in pediatrics, the FDA, the Centers for Disease Control and Prevention, and the American Academy of Pediatrics have recommended against off-label prescription of the coronavirus disease 2019 vaccine. Several commentaries consider a case in which parents ask their child's pediatrician to prescribe the vaccine for their 11-year-old with special health care needs before approval or authorization in her age group. The first commentary considers the potential benefits and risks to the patient, as well as to the family, the provider, and society, emphasizing the unknown risks in younger patients and the need for adequate informed consent. The second commentary describes an algorithm and principles for evaluating off-label prescribing and argues that the current benefits of prescribing Comirnaty off label to children <12 do not outweigh the risks. The third commentary addresses ethical and legal issues, ultimately calling on federal agencies to remove legal barriers to making the vaccine available to children in age groups that currently lack authorization., Competing Interests: FINANCIAL DISCLOSURES: The authors have indicated they have no financial disclosures relevant to this article to disclose., (Copyright © 2022 by the American Academy of Pediatrics.)

Background: Children with Developmental Language Disorder (DLD) have a significant deficit in spoken language ability which affects their communication skills, education, mental health, employment and social inclusion., Aim: The present study reports findings from a survey by EU network COST ACTION 1406 and aims to explore differences in service delivery and funding of SLT services for children with DLD across Europe and beyond., Methods and Procedures: The survey was completed by 5024 European professionals. COST countries were grouped into Nordic, Anglo-Saxon, Continental, Mediterranean, Central/Eastern and Non-European categories. The use of direct, indirect and mixed interventions, and their relationship to funding available (public, private or mixed) were considered for further analysis., Outcomes and Results: The results revealed that for direct therapy, there were more cases than expected receiving private funding. For indirect therapy, fewer than expected received private and more than expected public funding. For mixed therapy, fewer cases than expected received private funding., Conclusions and Implications: The results implies that other factors than evidence-based practices, practitioners experience, and patient preferences, drive choices in therapy. More research is needed to gain a better understanding of factors affecting the choice of therapy., (Copyright © 2021 The Authors. Published by Elsevier Ltd.. All rights reserved.)

While previous research has suggested that lowering athletes' heart rates can enhance sports performance, it is unknown whether slow-paced music might induce a lower heart rate and thereby improve some types of motor performance. In this study, we investigated the effects of different types of music during dart-throw training on both heart rate and dart-throwing performance in 45 ( M age = 19.7, SD  = 0.31 years) novice dart throwers who were randomly assigned to either a Slow Music Group (SMG), a Fast Music Group (FMG), or a Control Group (CG). All participants completed three dart-throwing blocks - Pre-Test, Practice, and Post-Test. During the Practice block, participants practiced dart-throwing with either slow-paced, fast-paced or no music according to their assigned group. We recorded the participants' heart rates and total dart-throwing accuracy scores during Pre-Test and Post-Test. Music-assisted dart-throw training with slow-paced music was effective in significantly inhibiting a performance-related increase in heart rate and was associated with the greatest dart throwing improvement after training.

Background: Understanding the factors that influence the implementation of health interventions in the context of education is essential to improving outcomes for children and young people with speech, language and communication needs (SLCN). Yet implementation considerations have not been adequately addressed when developing interventions for this context. The aim of this paper is to present a protocol for a scoping review of existing implementation frameworks that might guide SLCN intervention research in schools.  Methods: In accordance with scoping review guidelines, the proposed study will be conducted in  phases: (1) identifying potentially relevant studies, (2)  screening and selection of studies, (3) charting and extracting data from identified frameworks, (4) collating, summarising and reporting the results and (5) consulting with stakeholders. Two reviewers will conduct the screening and the data extraction phases independently. Identified frameworks will be collated, and described, and constructs from the frameworks will be categorised using domains from the Consolidated Framework for Implementation Research. A draft implementation science model will be proposed based on the findings of the scoping review. Conclusions: The findings of this review will provide guidance for researchers to begin to address implementation considerations when developing and facilitating the uptake of universal interventions for SLCN in the ordinary classroom, and ultimately can contribute towards improving outcomes for this vulnerable childhood population., Competing Interests: No competing interests were disclosed., (Copyright: © 2022 Gallagher A et al.)

This study aimed to advance our understanding of 5-year-olds' behavioral difficulties by modeling and testing both mediational protective and risk pathways simultaneously. Drawing on two national samples from different Western European countries-the United Kingdom (13,053) and Germany (2,022), the proposed model considered observed sensitive parental interactive behaviors and tested child vocabulary as protective pathways connecting parental education with children's behavioral outcomes; the risk pathways focused on negative parental disciplinary practices linking (low) parental education, parental distress, and children's difficult temperament to children's behavioral difficulties. Further, the tested model controlled for families' income as well as children's sex and formal child care attendance. Children with comparatively higher educated parents experienced more sensitive interactive behavior, had more advanced vocabulary, and exhibited fewer behavioral difficulties. Children with a comparatively higher level of difficult temperament or with parents who suffered from distress tended to experience more negative disciplinary behavior and exhibited more behavioral difficulties. Additionally, children's vocabulary skills served as a mechanism mediating the association between parental education and children's behavioral difficulties. Overall, we found similar patterns of results across the United Kingdom and Germany with both protective and risk pathways contributing simultaneously to children's behavioral development. The findings suggest that promoting parents' sensitive interactive behaviors, favorable disciplinary practices, and child's vocabulary skills have potential for preventing early behavioral difficulties., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Huang, Weinert, Wareham, Law, Attig, von Maurice and Roßbach.)

The belief that investors shift to gold during times of economic stress, resulting in a negative correlation between gold returns and stock returns, is not supported in both the 2007-09 financial crisis and during COVID-19. However, the gold-stock market relationship is positive in periods of negative real rates of return. The evidence points to gold as a safe haven in times of stock market volatility and negative interest rates., (© 2021 Elsevier Inc. All rights reserved.)

Background and Objective: Low language ability in early childhood is a strong predictor of later psychopathology as well as reduced school readiness, lower educational attainment, employment problems and involvement with the criminal justice system. Assessment of early language development is universally offered in many countries, but there has been little evaluation of assessment tools. We planned to compare the screening performance of two commonly used language assessment instruments., Methods: A pragmatic diagnostic accuracy study was carried out in five areas of England comparing the performance of two screening tools (Ages and Stages Questionnaire (ASQ) and Sure Start Language Measure (SSLM)) against a reference test (Preschool Language Scale, 5th edition)., Results: Results were available for 357 children aged 23-30 months. The ASQ Communication Scale using optimal cut-off values had a sensitivity of 0.55, a specificity of 0.95 and positive and negative predictive values of 0.53 and 0.95, respectively. The SSLM had corresponding values of 0.83, 0.81, 0.33 and 0.98, respectively. Both screening tools performed relatively poorly in families not using English exclusively in the home., Conclusion: The very widely used ASQ Communication Scale performs poorly as a language screening tool, missing over one-third of cases of low language ability. The SSLM performed better as a screening tool., Competing Interests: Competing interests: The Sure Start Language Measure was originally developed for the Sure Start Programme in England by the late project chief investigator Professor James Law., (© Author(s) (or their employer(s)) 2022.

Purpose: To determine whether the age-adjusted Charlson comorbidity index (age-CCI) in sino-orbital fungal disease patients correlates with disease-specific mortality., Methods: Hospital billing systems at 2 academic institutions were queried for patients with ICD-9, ICD-10, and CPT codes used in fungal disease who also had orbital disease and significant visual loss. Thirty-two patients at Institution A and 18 patients at Institution B met the inclusion criteria of microbiologic or pathologic confirmation of fungal infection and completion of inpatient ophthalmology evaluation. Patients without radiographic abnormality in the sinus or orbit were excluded. Demographic, diagnostic, treatment, and outcome variables were recorded. Our primary outcome was death due to fungal disease., Results: Of the 50 medical records examined, 44 patients met the criteria for fungal-related death outcome on multivariate analysis. The regression coefficient for age-CCI and fungal-related mortality was 0.242 (95% CI, 0.012-0.779) with a p value of 0.038., Conclusions: Age-CCI is significantly associated with fungal-related mortality. This relationship remains significant when controlling for 5 covariates of fungal organism phylum, presence or absence of CNS disease, exenteration, local treatment use, and presence or absence of an immunosuppressive diagnosis. Age-CCI shows promise as a clinical and research tool in the evaluation of invasive fungal disease involving the orbit., (Copyright © 2021 The American Society of Ophthalmic Plastic and Reconstructive Surgery, Inc.)

Background: Studies have highlighted the relationship between early childhood experiences and later language and communication skills on the one hand and social and emotional adjustment on the other. Less is known about this relationship between different types of early experiences and their relationship to different communication skills over time. Equally important is the extent to which the child's behaviour is related to later outcomes affecting the relationship between the child's environment and aspects of their communication development. Method: Drawing on data from 5,000 children in Growing Up in Scotland, a representative sample of children born in 2003. This paper looks are the differential relationships between home learning environment (HLE) (reads books/storeys, engages in painting or drawing, reads nursery rhymes and teaches letter/shapes and parental mental health (PMH) (Depression, Anxiety and Stress Scale (DASS) in the first year of life and both structural language skills ("Listening Comprehension" and "Expressive Vocabulary" subtests of The Wechsler Individual Achievement Tests) and pragmatic competence (The Children's Communication Checklist) at 11 years and explores the extent to which they are mediated by social and emotional adjustment at school entry. Results: PMH was associated with pragmatics but not listening comprehension or vocabulary. By contrast HLE was associated with all three measures of communication. In the final mediated model social and emotional adjustment mediated the relationship between PMH and all three measures of communication. The mediation was statistically significant for the relationship between HLE and both pragmatics and listening comprehension but not for expressive vocabulary. The results are discussed in terms of the relationships concerned and what they tell us about the potential for targeted early interventions. Conclusions: The mediating role of socio-emotional adjustment at school entry points to the need for careful monitoring of children's social and emotional development in primary and middle childhood. Services and policy aimed at improving child outcomes through improving home learning environments must work hand in hand with those responsible for offering support for the mental health, social-emotional adjustment and wellbeing of parents and children from birth and into the school years., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Law, Tamayo, Mckean and Rush.)

Background: Thyroid hormones are essential for the full thermogenic response of brown adipose tissue (BAT) and have been implicated in dermal temperature regulation. Nevertheless, persistent cold-intolerance exists among a substantial proportion of hypothyroid patients on adequate levothyroxine (LT4) substitution., Materials and Methods: To assess if skin temperature and activation of BAT during treatment with liothyronine (LT3) differs from that of LT4 treatment, fifty-nine female hypothyroid patients with residual symptoms on LT4 or LT4/LT3 combination therapy were randomly assigned in a non-blinded crossover study to receive monotherapy with LT4 or LT3 for 12 weeks each. Change in supraclavicular (SCV) skin temperature overlying BAT, and sternal skin temperature not overlying BAT, during rest and cold stimulation were assessed by infrared thermography (IRT). In addition, abundance of exosomal miR-92a, a biomarker of BAT activation, was estimated as a secondary outcome., Results: Cold stimulated skin temperatures decreased less with LT3 vs . LT4 in both SCV (mean 0.009°C/min [95% CI: 0.004, 0.014]; P <0.001) and sternal areas (mean 0.014°C/min [95% CI: 0.008, 0.020]; P <0.001). No difference in serum exosomal miR-92a abundance was observed between the two treatment groups., Conclusion: LT3 may reduce dermal heat loss. Thermography data suggested increased BAT activation in hypothyroid patients with cold-intolerance. However, this finding was not corroborated by assessment of the microRNA biomarker of BAT activation., Clinical Trial Registration: ClinicalTrials.gov, identifier NCT03627611., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Bjerkreim, Hammerstad, Gulseth, Berg, Lee-Ødegård, Rangberg, Jonassen, Budge, Morris, Law, Symonds and Eriksen.)

Background: Understanding the factors that influence the implementation of health interventions in the context of education is essential to improving outcomes for children and young people with speech and language needs (SLCN). Yet implementation considerations have not been adequately addressed when developing interventions for this context. The aim of this paper is to present a protocol for a scoping review of existing implementation frameworks that might guide SLCN intervention research in schools.  Methods: In accordance with scoping review guidelines, the study will be conducted in six phases: (1) identification of the research question, (2) identification of potentially relevant studies of Implementation Science frameworks, (3) study screening and selection, (4) charting and extracting data from identified frameworks, (5) collating, summarising and reporting the results and (6) consultation with stakeholders. Two reviewers will conduct the screening and extraction stages independently. Identified frameworks will be collated, and described, and constructs from the IS frameworks will be categorised using domains from the Consolidated Framework for Implementation Research. A draft implementation science model will be proposed based on the findings of the scoping review. Conclusions: The findings of this review will provide guidance for researchers to begin to address implementation considerations when developing and facilitating the uptake of universal interventions for SLCN in the ordinary classroom, and ultimately can contribute towards improving outcomes for this vulnerable childhood population., Competing Interests: No competing interests were disclosed., (Copyright: © 2021 Gallagher A et al.)

Background: The COVID-19 pandemic led to changes in patterns of presentation to emergency departments. Child health professionals were concerned that this could contribute to the delayed diagnosis of life-threatening conditions, including childhood cancer (CC) and type 1 diabetes (T1DM). Our multicentre, UK-based service evaluation assessed diagnostic intervals and disease severity for these conditions., Methods: We collected presentation route, timing and disease severity for children with newly diagnosed CC in three principal treatment centres and T1DM in four centres between 1 January and 31 July 2020 and the corresponding period in 2019. Total diagnostic interval (TDI), patient interval (PI), system interval (SI) and disease severity across different time periods were compared., Results: For CCs and T1DM, the route to diagnosis and severity of illness at presentation were unchanged across all time periods. Diagnostic intervals for CCs during lockdown were comparable to that in 2019 (TDI 4.6, PI 1.1 and SI 2.1 weeks), except for an increased PI in January-March 2020 (median 2.7 weeks). Diagnostic intervals for T1DM during lockdown were similar to that in 2019 (TDI 16 vs 15 and PI 14 vs 14 days), except for an increased PI in January-March 2020 (median 21 days)., Conclusions: There is no evidence of diagnostic delay or increased illness severity for CC or T1DM, during the first phase of the pandemic across the participating centres. This provides reassuring data for children and families with these life-changing conditions., Competing Interests: Competing interests: None., (© Author(s) (or their employer(s)) 2021.

Interest in brown adipose tissue remains high a decade after it was determined to be present outside of the neonatal period. In vivo imaging, however, has remained a challenge due to the lack of a imaging modality suitable for large healthy-volunteer studies, post-prandial investigations and vulnerable groups, such as children. Infrared thermography is increasingly accepted as a valid, non-invasive and flexible alternative but there is a wide approach to analysis between different groups. Defining the region of interest with anatomical borders rather than using a simple polygon may have advantages in terms of consistency but makes image analysis slower, limiting some applications. Our novel semi-automated method, using a custom-built graphical user interface, allows an 86% improvement in speed of image analysis (54.9 (38.3-71.4) seconds/image) without increases in variation between analysers or with repeated analysis. The improved efficiency demonstrated makes feasible larger studies, longer imaging periods or increased image acquisition frequency, providing an opportunity to study novel features of brown adipose tissue function., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2021 Published by Elsevier B.V.)

Purpose: The authors sought to examine relationships between CT metrics derived via an automated method and clinical parameters of extraocular muscle changes in thyroid eye disease (TED)., Methods: CT images of 204 orbits in the setting of TED were analyzed with an automated segmentation tool developed at the institution. Labels were applied to orbital structures of interest on the study images, which were then registered against a previously established atlas of manually indexed orbits derived from 35 healthy individuals. Point-wise correspondences between study and atlas images were then compared via a fusion algorithm to highlight metrics of interest where TED orbits differed from healthy orbits., Results: Univariate analysis demonstrated several correlations between CT metrics and clinical data. Metrics pertaining to the extraocular muscles-including average diameter, maximum diameter, and muscle volume-were strongly correlated (p < 0.05) with the presence of ocular motility deficits with regards to the superior, inferior, and lateral recti (with exception of superior rectus motility deficits being mildly correlated with muscle volume [p = 0.09]). Motility defects of the medial rectus were strongly correlated with muscle volume, and only weakly correlated with average and maximum muscle diameter., Conclusions: The novel method of automated imaging metrics may provide objective, rapid clinical information which may have utility in prevention and recognition of visual impairments in TED before they reach an advanced or irreversible stage and while they are able to be improved with immunomodulatory treatments., Competing Interests: L.A.M. is a consultant to Horizon Therapeutics.

Methyl groups are ubiquitous in biologically active molecules. Thus, new tactics to introduce this alkyl fragment into polyfunctional structures are of significant interest. With this goal in mind, a direct method for the Markovnikov hydromethylation of alkenes is reported. This method exploits the degenerate metathesis reaction between the titanium methylidene unveiled from Cp 2 Ti(μ-Cl)(μ-CH 2 )AlMe 2 (Tebbe's reagent) and unactivated alkenes. Protonolysis of the resulting titanacyclobutanes in situ effects hydromethylation in a chemo-, regio-, and site-selective manner. The broad utility of this method is demonstrated across a series of mono- and di-substituted alkenes containing pendant alcohols, ethers, amides, carbamates, and basic amines., (© 2021 Wiley-VCH GmbH.)

Intraosseous hemangiomas are rare bony neoplasms that infrequently develop in the calvarium or facial bones. Due to their highly vascular nature, biopsy or resection of these tumors can present a surgical challenge, with reports of significant blood loss during tumor resection. Traditional surgical resection of intraosseous hemangiomas often includes the use of high speed oscillating or sagittal saws. Ultrasonic aspirators, which spare adjacent soft-tissue structures and minimize blood loss, have been successfully used in resection of firm soft tissue masses of the orbit; however, this technology has not been demonstrated in the treatment of a vascular tumor in the orbit. The authors present the case of a 37-year-old woman who presented with an intraosseous hemangioma at the left inferior orbital rim and maxilla; the mass was successfully resected with the aid of a Sonopet Ultrasonic Aspirator bone knife. The knife allowed for simultaneous emulsification and cautery of the bone encasing the mass with low risk to sensitive surrounding tissue., Competing Interests: L.M. is a consultant for Horizon Therapeutics.

Background: Brown adipose tissue (BAT) is essential to maintain body temperature. Its ability to convert chemical energy in glucose and free fatty acids to heat is conferred by a unique protein, UCP-1. BAT activity is greatest in children and adolescents, declining through adulthood. Blood glucose concentrations outside the normal nondiabetic range are common in type 1 diabetes and hyperglycaemia leads to insulin resistance in muscle and white adipose tissue, but whether this applies to BAT, is not known., Method: To investigate the effect of type 1 diabetes on BAT activity, we measured the supraclavicular temperature of 20 children with type 1 diabetes and compared them to 20 age-matched controls, using infrared thermography., Results: The diabetes group had lower stimulated supraclavicular temperatures (diabetes group: 35.03 (34.76-35.30)°C; control group: 35.42 (35.16-35.69)°C; p = 0.037) and a reduced response in relative temperature following cold stimulation, after adjusting for BMI (diabetes group: 0.11 (0.03-0.18)°C; control group: 0.22 (0.15-0.29)°C; p = 0.034). In the diabetes group, there was no association between glycaemic measures and supraclavicular temperatures, but the method of insulin delivery may significantly affect the change in supraclavicular temperature with stimulation (injections: 0.01 (-0.07-0.09)°C; pump: 0.15 (0.04-0.26)°C; p = 0.028)., Conclusions: While further work is needed to better understand the glucose-insulin-BAT relationship, one possible explanation for the reduced supraclavicular temperature is that exogenous, unlike endogenous, insulin, is not suppressed by the activity of the sympathetic nervous system, preventing lipolysis-driven activation of BAT., (© 2020 John Wiley & Sons A/S.

Purpose: To assess whether aggressive behavior and emotional problems from early childhood onwards are related to academic attainment at the end of primary education, and whether these associations are independent of attention problems., Methods: Data on 2546 children participating in a longitudinal birth cohort in Rotterdam were analyzed. Aggressive behavior, attention and emotional problems at ages 1½, 3, 5 and 10 years were assessed with the Child Behavior Checklist. Academic attainment at the end of primary school (12 years of age) was measured with the CITO test, a national Dutch academic test score., Results: Aggressive behavior from age 1½ to 10 years was negatively associated with academic attainment, but these associations attenuated to non-significance when accounting for comorbid attention problems. For emotional problems, first, only problems at 10 years were associated with poorer academic attainment. Yet, when accounting for attention problems, the association reversed: more emotional problems from 1½ to 10 years were associated with a better academic attainment. Attention problems at ages 1½ to 10 years were negatively associated with academic attainment, independent of comorbid emotional problems or aggressive behavior., Conclusions: Attention problems across childhood are related to a poorer academic attainment, while emotional problems predicted better academic attainment. Moreover, the relationship between aggressive behavior and academic attainment was explained by comorbid attention problems. Future research should determine the mechanisms through which attention problems and emotional problems affect academic attainment, to inform strategies for the promotion of better educational attainment.

Purpose: To describe the experience of 4 oculoplastic surgeons with porcine bladder matrix for periocular anterior lamella and donor site skin defects either as stand-alone treatment or in conjunction with other reconstructive procedures. The authors hypothesized that defect size and location influence the requirement for additional matrix treatments or ancillary procedures., Methods: Following the Institutional Review Board approval, the authors conducted a retrospective review of 17 patients treated with porcine bladder matrix at 2 oculoplastic practices between 2016 and 2018. Powdered matrix was applied to the skin defect and overlaid with a matrix sheet. Subsequent rounds of matrix treatment or other reconstructive procedures were performed as necessary. Defect size and location were correlated to the number of ancillary matrix treatments or surgical procedures via univariate analysis., Results: Twenty-five sites (21 primary and 4 donor) in 17 individuals (8-95 years, M = 58.8 years, 10 males) were treated with porcine bladder matrix. All wounds healed successfully. Additional matrix treatments were administered at 5 sites. Ancillary procedures were performed for 7 sites. Upper lid involvement and larger defect size tended to require additional ancillary procedures (p = 0.006), while lower eyelid and other periocular defects required fewer procedures (p < 0.001)., Conclusion: Porcine bladder matrices are useful adjuncts to healing periocular anterior lamella defects in various settings. Such repairs are useful in nonsurgical candidates, but must take into account varying levels of complexity based on lesion location. Smaller defects are more conducive to application of matrices as stand-alone treatment, while larger or upper eyelid defects often require additional procedures., Competing Interests: The authors have no financial or conflicts of interest to disclose., (Copyright © 2021 The American Society of Ophthalmic Plastic and Reconstructive Surgery, Inc.)

Background: Many healthcare and educational services providers have undergone a rapid transition from a face-to-face to a tele-practice mode of service delivery in the context of the COVID-19 outbreak. This, in turn, has led to a need to understand better the evidence underpinning such moves. Based on a review of existing reviews, this paper critically analyses the relevant literature related to intervention with children with communication disabilities drawing on the COM-B model., Methods & Procedures: Ten reviews were identified following a systematic searching of electronic databases. These were then coded according to both PRISMA criteria and the components of the COM-B model. Based on these findings, a critical analysis of the state of the tele-practice intervention literature is discussed and fed into evidence-based advice for practitioners transitioning to this mode of service delivery., Outcomes & Results: The COM-B mapping suggests that the existing literature has provided primary evidence for physical opportunity and reflective motivation (e.g., participants have the time to take part and the necessary materials, as well as a desire to do it). It has also focused on elements of social opportunity (e.g., having support and prompts from others to take part). However, there are significant gaps in the description and analysis of both physical and psychological capability components., Conclusions & Implications: Whilst the evidence for tele-practice interventions for children and young people with communication disabilities is growing, it is also lacking a comprehensive framework to support its implementation. In times of rapid transitions, researchers and practitioners alike need to understand how to evaluate comprehensively the impact of changing the mode of intervention delivery. The COM-B model provides a powerful tool to reflect on the key elements for the successful design and implementation of tele-practice interventions. What this paper adds What is already known on this subject Tele-practice has been a feature of service delivery for speech and language therapists working with children and young people with speech and language disorders for many years, as it has in other areas of practice. This came into sharp focus during 2020 during the 'lock-down' following the start of the COVID-19 pandemic when most practice went online. What this paper adds to existing knowledge This study set out to provide a framework for understanding service delivery, drawing on the COM-B behaviour change model. This is applied using a rapid review methodology to 10 systematic and narrative reviews of the existing literature published since 2005. The findings suggest that while most studies demonstrated efficacy, there was a lack of information regarding specific aspects of the model which would affect their implementation. What are the potential or actual clinical implications of this work? It is anticipated that the paper has the potential to have a direct bearing on how tele-practice services for children and young people with speech and language disorders will be delivered in the future. The paper concludes with a series of recommendations for practice and research in terms of the application of the COM-B model to tele-practice in speech and language therapy., (© 2021 The Authors.

Internal focus attention strategies have been found to diminish motor performance. This study attempted to elucidate this finding using the constrained action hypothesis and the theory of reinvestment through exploring their underlying mechanisms. Sixty-one young participants completed a self-paced "dart throwing" motor task to examine the effects of internal focus instruction, compared with no focus instruction, on conscious motor processing (reinvestment), psychological stress, and motor performance. Participants threw darts with standardized internal focus and no focus instructions given before each trial block of dart throwing. Motor performance was indicated by the throw accuracy and throw time. Stress was measured using a galvanic skin response probe. An insight into real-time conscious motor processing (reinvestment) was provided by the electroencephalography coherence between T3 and Fz locations on the scalp. Results indicated that internal focus instruction could cause participants to have lower throw accuracy (p = 0.008), longer throw time (p = 0.001), higher stress (p = 0.001) and higher real-time conscious motor processing (reinvestment) (p = 0.001) than no focus instruction. The significant results imply that internal focus instruction should be avoided in the self-paced motor task learning due to its detrimental effects.

Background: The cultural and language diversity across many European countries presents a range of challenges and opportunities for speech and language therapists and other practitioners working with children with developmental language disorders (DLD) and their families., Objective: The aim of this study was to explore practitioners' perceptions of cultural and linguistic differences in response to children with DLD across different countries., Methods: A survey was developed by practitioners and researchers working with children with DLD across Europe and beyond as part of the work of Cost Action IS1406. Data from 1,358 practitioners from 8 European countries - Ireland, UK, Bulgaria, Poland, Croatia, Spain, Norway and Sweden - and 2 neighbour countries - Turkey and Lebanon - were included in the present analyses, which address two groups of questions. The first focuses on practitioners' perceptions of the way that parents think about cultural differences and their relationship to language development in their children. The second concerns the extent to which practitioners consider themselves to have the skills to work with children from other cultures and using different languages., Results/conclusions: Most countries present a similar profile with intermediate results about their perception of cultural issues, but Lebanon and Turkey are the group with the most positive responses. In terms of bilingual issues most practitioners indicated that they only worked in their country's primary language. The only country where this was not the case was Lebanon. Professionals from Spain and Lebanon form a subgroup in terms of their confidence to work with different cultural/language groups. The paper highlights both the universal importance of cultural and linguistic competence in managing young children's needs and indicates that in most cases professionals do not think they have the necessary expertise to work with cultural and linguistic diversity., (© 2020 S.

Adipose tissue is usually laid down in small amounts in the foetus and is characterised as possessing small amounts of the brown adipose tissue-specific mitochondrial uncoupling protein (UCP)1. In adults, a primary factor determining the abundance and function of UCP1 is ambient temperature. Cold exposure causes activation and the rapid generation of heat through the free flow of protons across the mitochondria with no requirement to convert ADP to ATP. In rodents, housing at an ambient temperature below thermoneutrality promotes the appearance of beige like adipocytes. These arise as discrete regions of UCP1 containing cells in white fat depots. There is increasing evidence to show that to gain credible translational results on brown and beige fat function in rodent models that they should be housed at thermoneutrality. This not only reflects the type of environment in which humans spend a majority of their time, but is in accord with the rise of global temperature caused by industrialisation and the uncontrolled burning of fossil fuels. There is now good evidence in adult humans, that stimulating brown fat can improve glucose homeostasis which can be achieved either by nutritional or pharmacological interventions. The challenge, therefore, is to establish credible developmental models in animals maintained at thermoneutrality which will elucidate the true impact of nutrition. The primary focus should fall specifically on the components of breast milk and how these modulate long term effects on brown or beige fat development and function.

Purpose: Considerable progress has been made in recent years in generating external evidence underpinning interventions for children with developmental language disorder (DLD), but less is known about the practitioner decision-making process underpinning such interventions and whether such decisions are context specific or are internationally generalizable., Methods: An online survey about clinical practice was developed by members of COST Action IS1406, an EU-funded research network, which included representation from 39 countries. The participants were 2,408 practitioners who answered questions in relation to their decision making for a specific child of their choosing with DLD. Analysis of open-ended questions was undertaken, and data were converted into codes for the purpose of quantitative analysis., Results: Although a wide range of intervention approaches and rationales were reported, the majority of responses referenced a client-centred approach. Level of functioning was used as a rationale only if a child had severe DLD. Practitioners with university level education or above were less likely to report basing intervention on client-centred factors. A number of differently named interventions with variable theoretical and empirical underpinnings were used in different countries., Conclusions: Specific client and practitioner characteristics have an impact on the intervention approaches and rationales adopted across countries. A limited number of practitioners reported use of external scientific evidence, which suggests that there should be more initiatives in basic training of practitioners and continuing professional development to encourage the uptake of scientific evidence-based practice., (© 2021 S.

Purpose: Injury to the eye and/or orbital and adnexal structures associated with antiquated muzzle-loading firearms has not, to our knowledge, been characterized with the exception of a single case report., Methods: A retrospective chart review of 7 patients treated at Vanderbilt University Medical Center from 2003 to 2017 who sustained traumatic injuries to the ocular and/or orbital structures secondary to the discharge of muzzle-loading firearms. The study was approved by the Vanderbilt Institutional Review Board., Results: In 6/7 cases, injuries occurred secondary to the muzzle-loading firearm exploding due to dysfunction or misuse. Foreign material deriving from the firearm was retained in 3/7 patients. Initial examination of the orbit and adnexa revealed 5/7 individuals sustaining orbital fractures and 6/7 with facial lacerations (including 2 with eyelid lacerations); none had evidence of a lacrimal duct injury. Three patients suffered globe injuries (1 closed-globe and 2 open-globe). Visual acuity at last follow-up was ≥20/20 in 12/14 eyes examined. Surgical intervention was required in the treatment of 4/7 individuals (including 3/7 requiring intervention for sustained orbital fractures). No individuals were wearing eye protection at the time of injury. All individuals survived their injuries., Conclusions: The operation of muzzle-loading firearms poses a unique risk of injury to the operator. The resultant injuries in this case series were primarily due to the explosion of the firearm, which subsequently appear similar to orbital and ocular blast injuries caused by explosive weapons. Orbital injuries and more potentially more devastating ocular injuries may have been prevented by protective eyewear., Competing Interests: Louise A. Mawn is a Horizon Therapeutics Speaker.

Background: Parent-child interaction therapies are commonly used by speech and language therapists (SLTs) when providing services to young children with language learning difficulties. However, the way parents react to the demands of such interventions is clearly important, especially for those from socially disadvantaged backgrounds. Parents play a central role in the therapy process so to ensure parent engagement, and to maximize intervention effectiveness, parents' views must be considered., Aims: To explore the expectations and experiences of parents from socially disadvantaged backgrounds who had taken part in a parent-child interaction programme aimed at promoting language development in 2-3 year olds with language difficulties., Methods & Procedures: The sample included parents who had a child aged 2-3 years and had attended a parent-child interaction programme to promote their child's language development. Parents were eligible to take part if they were living in the 30% most deprived areas in a city in the North of England that constituted the study site. Ten parents participated in a qualitative semi-structured face-to-face interview in the home. Framework analysis was used to analyse the interview transcripts., Outcomes & Results: Parents' expectations before taking part in parent-child interaction interventions contribute to how they may engage throughout the intervention process. Barriers include parents' uncertainty about the nature of the intervention and differing attitudes regarding intervention approaches and strategies. Facilitators during the intervention process include gaining support from other parents, reassurance from the SLT regarding their child's language development, and their own ability to support their child's language learning, as well as increased confidence in how they support their child's development., Conclusions & Implications: Parents respond very differently to parent-child interaction intervention for children with language difficulties, depending on their expectations and attitudes towards intervention. Thus, it is critical that these different perspectives are understood by practitioners before intervention commences to ensure successful engagement. What this paper adds What is already known on this subject Parent-child interaction interventions are widely used to promote child language development. Parents play a central role in the therapy process of such interventions, so to maximize effectiveness, parents must be appropriately 'engaged' in that intervention. This involves attending, fully participating and having appropriate attitudinal and/or emotional involvement. The reciprocal nature of engagement means that parents are more likely to become engaged in intervention over time when they are supported by their SLT. What this paper adds to existing knowledge Parental expectations about the intervention process vary considerably and often need to be negotiated before the start of intervention. Reassurance and supporting positive attitudes to co-working with their SLT may be particularly important for families living with social disadvantage. Supporting parent engagement in parent-child interaction programmes can contribute to the parents' capability to continue implementing language-promoting strategies outside the intervention context and beyond the end of therapy. What are the potential or actual clinical implications of this work? Parents have different expectations regarding programme involvement. Therefore, having a two-way, open dialogue between parents and SLTs from the beginning is clearly important, not only as a way of sharing information but also to build on parents' understanding of what the intervention will involve and trust that the SLT will be able to deliver the intervention in collaboration with the parent. SLTs can enhance parent engagement by supporting parents to feel confident and providing reassurance in terms of their child's development and how they can support their child's language learning., (© 2020 Royal College of Speech and Language Therapists.)

Background: This study aims to determine whether the Parental Responsiveness Rating Scale (PaRRiS) completed at child age 24-30 months can be used by community child health nurses (CCHNs) to reliably measure the quality of parent-child interactions in practice., Methods: A mixed-methods design was used involving CCHNs working in public health settings. Five CCHNs recruited from the North-East of England were trained to use PaRRiS. Thirty parent-child dyads attending their routine 24-30-month check were observed. Nurses rated parent-child dyads during 5 min of free-play using PaRRiS. The free-play sessions were video recorded and rated blind by the first author to the nurse observation. Semi-structured phone interviews were conducted with the five CCHNs once observations of parent-child interactions were complete. Interviews were audio-recorded, transcribed, anonymized and thematically analyzed., Results: Two-thirds of participating parents were mothers. Half the families (15/30) were from the 10% most deprived areas based on the English Index of Multiple Deprivation. The average PaRRiS score was 3.03 [standard deviation (SD) = 0.8; all ratings were <5.0]. Reliability between the first author ('gold standard') and CCHNs was excellent [Intra-class correlation coefficient (ICC): 0.85; 95% confidence interval (CI): 0.67-0.93]. CCHNs found PaRRiS aligned well with current practice and was acceptable to parents. There was no evidence of a relationship between social disadvantage and PaRRiS scores., Conclusions: With further development and evaluation work, PaRRiS could potentially be incorporated into existing universal health services to provide child health nurses with an additional tool for identifying families most likely to be in need of parent-child interaction interventions., (© The Author(s) 2019.

Purpose: We evaluated the relative effectiveness of combined recession-resection of vertical rectus muscles versus superior rectus recession with inferior oblique weakening for patients who underwent surgical correction of chin-down abnormal head position (AHP) associated with infantile nystagmus syndrome (INS)., Design: Retrospective interventional case series., Methods: This is a review of 22 patients who underwent surgical correction of chin-down vertical AHP associated with INS at an academic institution. The primary outcome was collapse of AHP. Unfavorable outcomes included repeat surgery and induced strabismus, in addition to failure of collapse of AHP., Results: Twenty-two patients had chin-down AHP. Recession-resection (bilateral superior rectus recession 6-9 mm; bilateral inferior rectus resection 5-9 mm) was performed in 11 cases; weakening of both elevators (bilateral superior rectus recession 5-8 mm, bilateral inferior oblique recession or myectomy) occurred in 11 cases. Unfavorable outcome rates were 64% (7/11) compared with 18% (2/11), respectively (P = .03). Reoperation was performed for 6 of 22 patients. Five patients were from the recession-resection group, namely 3 for induced V-pattern esotropia, 1 for alternating esotropia, and 1 to correct recurrent AHP. The last of the 6 who required reoperation was in the elevator weakening group, and required correction of a recurrent AHP (P = .06)., Conclusions: While recession-resection of the vertical recti and weakening of both elevators each produce acceptable collapse of chin-down AHP, the former frequently induces a V-pattern esotropia requiring reoperation., (Copyright © 2020 Elsevier Inc.
