Analysis of international public-sector contributions to Food and Drug Administration (FDA)-approved drugs and vaccines allows for a more thorough examination of the global biomedical innovation ecosystem by institution of origin. Using new and existing methods, we have identified 364 FDA-approved drugs and vaccines approved from 1973 to 2016 discovered in whole or in part by Public Sector Research Institutions (PSRIs) worldwide. We identified product-specific intellectual property contributions to FDA-approved small molecule and biologic drugs and vaccines from the FDA Orange Book, our peer network, published studies, and three new sources: reports of medical product manufacturers' payments to physicians and teaching hospitals under The Sunshine Act of 2010, a paper by Kneller and 64 royalty monetization transactions by academic institutions and/or their faculty that one of us (AS) maintains. We include a total of 293 drugs discovered either wholly by a US PSRI or jointly by a U.S. and a non-U.S. PSRI. 119 FDA-approved drugs and vaccines were discovered by PSRIs outside the U.S. Of these, 71 were solely discovered outside the US, while 48 also involved intellectual property contributions by US PSRIs. In the context of the global public sector landscape, the US dominates drug discovery, accounting for two-thirds of these drugs and many of the important, innovative vaccines introduced over the past 30 years. Contributions by Canada, UK, Germany, Belgium, Japan, and others each amount to 5.4% or less of the total. [ABSTRACT FROM AUTHOR]

Introduction: This retrospective cohort study recognizes a profound need to address rising rates of maternal morbidity and mortality, especially its disproportionate impact on ethnic and racial minorities. Timely access to high-quality prenatal care is essential, the absence of which is associated with increased risk of adverse maternal and fetal outcomes. The persistence of racial and ethnic disparities in pregnancy outcomes, despite accounting for income and education level, suggests that barriers to care are also significantly limited by psychosocial and health system barriers. Methods: This retrospective cohort study analyzed several potential barriers to prenatal care among postpartum patients who delivered at Loyola University Medical Center in Maywood, Illinois, such as transportation, parking, childcare, clinic wait times, scheduling difficulties, and knowledge about the impact of COVID-19 on pregnancy. Participants were screened daily for eligibility and consented to participate from February to May 2022, a total of three months. Eligible patients were given a 10-question paper survey that also assessed out-of-pocket costs and suggestions to improve prenatal care attendance and satisfaction. During the study period, there were 251 eligible deliveries. 197 patients (77.3%) were consented and participated in the survey. 194 (98.4%) were eligible for post-chart review; 21 patients (10.6%) declined to participate, 33 patients (16.8%) did not complete the survey, and 3 surveys (1.5%) were lost. Retrospective chart reviews were conducted for PNC utilization, pregnancy comorbidities and outcomes, and demographic information. Data underwent Fischer analyses, chi-squared analyses, and ANOVAs. Institutional Review Board-approved, participants consented for research and quality improvement, including medical record data use. Results: Among 194 patients, average reported barriers to PNC were 2.14, with "difficulty scheduling appointments" (39.6%) and "couldn't leave work or school" (30.2%) most common. Despite most patients reporting a similar number of barriers, timing disparities based race and ethnicity, education, and income were observed. Hispanic patients initiated PNC later than non-Hispanic White patients (13w6d vs. 10w5d; p = 0.009). Twelfth-grade education or less initiated PNC bachelor's degree holders (16w vs. 11w; p < 0.001). Patients who made < 45 k annually initiated later than > 140 k (13w3d vs. 9w1d; p = 0.02). Patients who reported "long wait times" initiated prenatal care an average of 2w2d later than patients not facing this barrier, at 14w1d vs. 12w0d, respectively (p = 0.01). Conclusions: Lower socioeconomic status and ethnic minority patients exhibit delayed PNC start that are linked to adverse outcomes. Noteworthy discrepancies within the surveyed cohorts, despite comparable reported barriers, hint at the existence of supplementary, interconnected obstacles specific to these patients. Future efforts should tackle common issues specific to various sociodemographic groups to address disparities in pregnancy outcomes. [ABSTRACT FROM AUTHOR]

The article reports on the investigation whether electrical pulses from deep-brain electrical stimulation electrodes implanted in the central thalamus could recruit and activate unused but functional cerebral networks in patients in the minimally conscious state (MCS). This work, which was conducted by Nicholas Schiff, a neurologist at the Weill Cornell Medical College in New York, together with Weill medical ethicist Joseph Fins, neurologist Joseph Giacino, and neurosurgeon Ali Rezai, focused on a single patient who was unable to follow commands consistently, communicate, or vocalize after severe traumatic brain injury. Schiff considers the team's effort not just an innovation in neurosurgery, but also in how MCS patient behavior is assessed and how doctors think on finding ethical ways.

Background: To assess quality of life and unmet needs after stroke, patient-reported outcome measures (PROMs) have gained increasing attention. However, patients' perspectives on assessing PROMs remain unclear, potentially hindering implementation into clinical practice. Therefore, this study explored patients' preferences on assessing PROMs after ischemic stroke. Methods: A paper-based questionnaire was sent to stroke survivors treated at the Department of Neurology, University of Leipzig, Germany. Health-related quality of life (HRQoL, EQ-5D-5L) and preferences regarding different aspects of data collection to assess PROMs were investigated and linked to socio-demographic and medical characteristics. Results: 158 persons were contacted and 80 replies were subsequently analyzed. Mean age was 70.16 years and mean HRQoL was 68.79 (visual analogue scale with a theoretical maximum of 100). Participants showed positive attitudes towards PROMs as they saw potential to improve care of other patients (n = 66/79; 83.54%) or to improve their own situation (n = 53/74; 71.62%). Participants preferred an annual interview after stroke (n = 39/80; 48.75%) and would preferably spend 15–30 min (n = 41/79; 51.90%) to answer a written survey (n = 69/80; 86.25%). The initially treating clinic was preferred as initiator of such surveys (n = 43/79; 54.43%). Stratification revealed that participants with more than 1 h of daily digital media usage preferred email as way of communication. Conclusions: For the first time, this study showed individual preferences on assessing PROMs after ischemic stroke, focusing on the way, time interval, duration, and initiation site of surveys. These insights might help to successfully implement PROMs after stroke and subsequently detect unmet needs and deficits in stroke care. [ABSTRACT FROM AUTHOR]

In the transition from paper to electronic workflow, the University of Colorado Health System's implementation of a new electronic health record system (EHR) forced all clinical groups to reevaluate their practices including the infrastructure surrounding clinical trials. Radiological imaging is an important piece of many clinical trials and requires a high level of consistency and standardization. With EHR implementation, paper orders were manually transcribed into the EHR, digitizing an inefficient work flow. A team of schedulers, radiologists, technologists, research personnel, and EHR analysts worked together to optimize the EHR to accommodate the needs of research imaging protocols. The transition to electronic workflow posed several problems: (1) there needed to be effective communication throughout the imaging process from scheduling to radiologist interpretation. (2) The exam ordering process needed to be automated to allow scheduling of specific research studies on specific equipment. (3) The billing process needed to be controlled to accommodate radiologists already supported by grants. (4) There needed to be functionality allowing exams to finalize automatically skipping the PACS and interpretation process. (5) There needed to be a way to alert radiologists that a specialized research interpretation was needed on a given exam. These issues were resolved through the optimization of the 'visit type,' allowing a high-level control of an exam at the time of scheduling. Additionally, we added columns and fields to work queues displaying grant identification numbers. The build solutions we implemented reduced the mistakes made and increased imaging quality and compliance. [ABSTRACT FROM AUTHOR]

Diabetic retinopathy(DR) is a health condition that affects the retinal blood vessels(BV) and arises in over half of people living with diabetes. Exudates(EX) are significant indications of DR. Early detection and treatment can prevent vision loss in many cases. EX detection is a challenging problem for ophthalmologists due to its different sizes and elevations as retinal fundus images frequently have irregular illumination and are poorly contrasting. Manual detection of EX is a time-consuming process to diagnose a mass number of diabetic patients. In the domain of signal processing, both SIFT (scale-invariant feature transform) and SURF (speed-up robust feature) methods are predominant in scale-invariant location retrieval and have shown a range of advantages. But, when extended to medical images with corresponding weak contrast between reference features and neighboring areas, these methods cannot differentiate significant features. Considering these, in this paper, a novel method is proposed based on modified KAZE features, which is an emerging technique to extract feature points and extreme learning machine autoencoders(ELMAE) for robust and fast localization of the EX in fundus images. The main stages of the proposed method are pre-processing, OD localization, dimensionality reduction using ELMAE, and EX localization. The proposed method is evaluated based on the freely accessible retinal database DIARETDB0, DIARETDB1, e-Ophtha, MESSIDOR, and local retinal database collected from Silchar Medical College and Hospital(SMCH). The sensitivity, specificity, and accuracy obtained by the proposed method are 96.5%, 96.4%, and 97%, respectively, with the processing time of 3.19 seconds per image. The results of this study are satisfactory with state-of-the-art methods. The results indicate that the approach taken can detect EX with less processing time and accurately from the fundus images.

The electronic medical record (EMR) has significantly improved efficiency in many areas of radiology workflow. Following implementation of an electronic protocol selection process for cross-sectional imaging at the University of Colorado Hospital, the interventional radiology (IR) division desired to have a similar tool. Evaluation of the IR workflow demonstrated the need for a multilayered solution, which accounted for consultation, physician review, authorization and scheduling, pre-procedural nursing evaluation, physician rounding, and resource allocation and prioritization. This paper outlines the rationale for and components of this process. [ABSTRACT FROM AUTHOR]

Physiological studies have found that the autonomic nervous system plays an important role in controlling blood pressure values. This paper, based on machine learning approaches, analysed short-term heart rate variability to determine differences in autonomic nervous function between hypertensive patients and normal population. The electrocardiogram (ECG) of hypertensive patients are 137 ECG recordings provided by Smart Health for Assessing the Risk of Events via ECG (SHAREE database). The RR intervals of healthy subjects include the data of 18 subjects from the MIT-BIH Normal Sinus Rhythm Database (nsrdb) and 54 subjects from the Normal Sinus Rhythm RR Interval Database (nsr2db). In this paper, each RR segment includes continuous 500 beats. Seventeen features were extracted to distinguish the hypertensive heart beat rhythms from the normal ones, and Kolmogorov-Smirnov test and sequential backward selection (SBS) were applied to get the best feature combinations. In addition, support vector machine (SVM), k-nearest neighbor (KNN) and random forest (RF) were applied as classifiers in the study. The performance of each classifier was evaluated independently using the leave-one-subject-out validation method. The best predictive model was based on RF and enabled to identify hypertensive patients by five features with an accuracy of 86.44%. The best five HRV features are sample entropy (SampEn), very low frequency spectral powers (VLF), root mean square of successful differences (RMSSD), ratio of low frequency spectral powers and high frequency spectral powers (LF/HF) and vector angle index (VAI). The results of the study show sympathetic overactivity and decreased parasympathetic tone in hypertensive patients. [ABSTRACT FROM AUTHOR]

Turning university research output into useful products such as drugs, devices and diagnostics requires skills, knowledge, and resources traditionally attributed to private industry. When it comes to intangibles such as care delivery models, informatics and algorithms, and the software behind smart wearables, the commercialization challenges are even greater. With notable exceptions, Academic Medical Centers have typically not excelled in advancing commercialization of such non-patent intellectual property (IP). We believe that this is in part because the traditional closed form university IP policy, formulated since Bayh–Dole (1980), is ill-suited to non-patent IP. In this paper, we reflect on the evolving challenges that new forms of healthcare-related discoveries, specifically non-patent IP, are placing on the traditional university intellectual property and technology transfer regime, and to offer suggestions on how universities can begin to modernize their IP policies to support the valorization of non-patent IP.

In this paper, we walk you through our challenges, successes, and experience while participating in a Global Health Outreach Project at the University College Hospital (UCH) Ibadan, Nigeria. The scope of the project was to install a Picture Archive and Communication System (PACS) to establish a centralized viewing network at UCH's Radiology Department, for each of their digital modalities. Installing a PACS requires robust servers, the ability to retrieve and archive studies, ensuring workstations can view studies, and the configuration of imaging modalities to send studies. We anticipated that we might experience hurdles for each of these requirements, due to limited resources and without the availability to make a site visit prior to the start of the project. While we ultimately experienced delays and troubleshooting was required at each turn of the install, with the help of dedicated volunteers both on and off-site and the UCH staff, our shared goal was accomplished.

Intratumoral heterogeneity poses a significant challenge to the diagnosis and treatment of recurrent glioblastoma. This study addresses the need for non-invasive approaches to map heterogeneous landscape of histopathological alterations throughout the entire lesion for each patient. We developed BioNet, a biologically-informed neural network, to predict regional distributions of two primary tissue-specific gene modules: proliferating tumor (Pro) and reactive/inflammatory cells (Inf). BioNet significantly outperforms existing methods (p < 2e-26). In cross-validation, BioNet achieved AUCs of 0.80 (Pro) and 0.81 (Inf), with accuracies of 80% and 75%, respectively. In blind tests, BioNet achieved AUCs of 0.80 (Pro) and 0.76 (Inf), with accuracies of 81% and 74%. Competing methods had AUCs lower or around 0.6 and accuracies lower or around 70%. BioNet's voxel-level prediction maps reveal intratumoral heterogeneity, potentially improving biopsy targeting and treatment evaluation. This non-invasive approach facilitates regular monitoring and timely therapeutic adjustments, highlighting the role of ML in precision medicine. [ABSTRACT FROM AUTHOR]

Introduction: The Utrecht Symptom Diary (USD) is a validated Dutch patient-reported outcome measurement (PROM) tool - based on the Edmonton Symptom Assessment System - to assess and monitor symptoms in cancer patients. The USD contains 11 items concerning frequently occurring symptoms in cancer patients (pain, sleeping problems, dry mouth, dysphagia, lack of appetite, abnormal stool, nausea, shortness of breath, fatigue, anxiety and depressed mood) and an item on overall well-being. For the outpatient USD 11 items concerning frequently occurring signs and symptoms in patients receiving chemotherapy and/or targeted therapy were added to the USD: taste alteration, oral pain, weight loss, diarrhoea, hair changes, skin problems, nail problems, eye problems, tingling, concentration problems and problems with sexuality. This current study aimed to evaluate the 11 added items on this treatment specific outpatient USD in cancer patients receiving intravenous chemotherapy and/or targeted therapy. Methods: Observational longitudinal retrospective cohort study including all adult outpatients with cancer receiving intravenous chemotherapy and/or targeted therapy in an academic hospital in the Netherlands who completed at least one outpatient USD as part of routine care (2012–2021). Relevance, comprehensiveness as well as criterion and construct validity were assessed. Results: 1733 patients who completed ≥ 1 outpatient USD during intravenous chemotherapy and/or targeted therapy were included for analysis. Relevance as well as comprehensiveness of the items on the outpatient USD in this patient population was shown. Criterion validation was demonstrated for all added items of the outpatient USD – except for the item on oral pain. An additional analysis showed that mouth problems were detected with both outpatient USD items oral pain and dry mouth. Construct validity was demonstrated for the items hair changes and skin and nail problems. Construct validity on eye problems was not tested due to the low number of paired outpatient USDs. Conclusions: The treatment specific outpatient USD is a validated PROM in outpatients with cancer receiving intravenous chemotherapy and/or targeted therapy. Considering its validity in this broad group of patients, we think the treatment-specific outpatient USD is widely applicable. In addition to providing tailored supportive symptom care, the USD-data can be used to increase knowledge about symptom burden in daily practice in this population. [ABSTRACT FROM AUTHOR]

In multicentric studies, data sharing between institutions might negatively impact patient privacy or data security. An alternative is federated analysis by secure multiparty computation. This pilot study demonstrates an architecture and implementation addressing both technical challenges and legal difficulties in the particularly demanding setting of clinical research on cancer patients within the strict European regulation on patient privacy and data protection: 24 patients from LMU University Hospital in Munich, Germany, and 24 patients from Policlinico Universitario Fondazione Agostino Gemelli, Rome, Italy, were treated for adrenal gland metastasis with typically 40 Gy in 3 or 5 fractions of online-adaptive radiotherapy guided by real-time MR. High local control (21% complete remission, 27% partial remission, 40% stable disease) and low toxicity (73% reporting no toxicity) were observed. Median overall survival was 19 months. Federated analysis was found to improve clinical science through privacy-friendly evaluation of patient data in the European health data space. [ABSTRACT FROM AUTHOR]

With the continuous advancement of medical research, the number of multi-center clinical studies has been steadily increasing, bringing about significant challenges to ethical review. Improving the efficiency and quality of ethical review has become a necessity driven by national policies and the development of the industry. Mutual recognition of ethical reviews is one of the most effective ways to enhance the efficiency of ethical review in multi-center clinical trials. The promotion of mutual recognition of ethical reviews is both feasible and practically significant; however, progress has been less than ideal. Through conducting surveys, this study attempts to understand the status of mutual recognition of ethical reviews in Jiangsu Province, identify the reasons hindering the implementation of mutual recognition, and propose possible solutions. The results indicate that while most medical and health institutions are aware of the policies related to mutual recognition of ethical reviews, the majority remain in a wait-and-see attitude. Ensuring policy guarantees and the high quality and homogeneity of ethical review across institutions are considered necessary conditions for achieving mutual recognition of ethical reviews.

Overcrowding is a worldwide problem, and long waiting times are associated with increased morbidity and even mortality of patients regardless of triage classification. Although there are many tools published in the literature that contribute to the reduction of overcrowding, for the Colombian population there are not many tools evaluated to reduce the length of stay of patients in the emergency department. This is a retrospective analytical study that compared whether there was a difference in patient definition time and ED length of stay between a group attended under an early care protocol (PAT) versus the usual protocol. Of the total of 969 patients included it was found that the group attended under the PAT protocol had a shorter definition time than the usual protocol, also the Emergency department length of stay (EDLOS) was significantly lower in the PAT group compared to the usual protocol. The implementation of the PAT protocol performed by emergency physicians allows a faster contact with the patient by the physician, and leads to a significant reduction of EDLOS, contributing to the reduction of overcrowding in the emergency department.

Background: Electrodiagnosis is a localizing, diagnostic, and prognostic tool for individuals with suspected neuromuscular diseases. In addition to detailed history taking and thorough clinical examination, correct execution and interpretation of these tests can provide vital insights into the underlying neuromuscular disorders and frequently guide the need for proper management decision. The request for an electrodiagnosis examination should include brief clinical information and a provisional clinical diagnosis; this enhances the efficient easy performance of the test. The current study aims to detect the pattern of neuromuscular diseases in the Alexandria Main University Hospital, Egypt, and to evaluate the quality of the referral system to the electrodiagnosis unit. Results: The study included 371 patients, out of which, 65% were referred from the Governmental Specialized Medical Councils and the Neurosurgery department. Although sensory complaints were the main reason for referral, yet 28.8% of patients did not show any electrodiagnosis abnormality. A compatible referral note led to shorter test times and fewer electromyography needle insertions. Conclusion: Disorders of the peripheral nerves are the most frequent neuromuscular diseases referred to the electrodiagnosis unit with carpal tunnel syndrome being the most common disorder. A compatible referral letter is necessary when requesting an electrodiagnosis test, to save the physician time and focus on targeted procedures. [ABSTRACT FROM AUTHOR]

Background and aim: The increasing frequency of heat waves worldwide is a major challenge for emergency care providers worldwide. The aim of this study was to analyze the clinical features, treatment options, and early outcomes of heat stroke patients presenting to a large academic emergency department (ED) in Hungary and to provide guidance in management for other emergency professionals. Methods: Patients presenting to the ED between June 1, 2024, and July 31, 2024, with a body temperature above 40 °C were analyzed in a retrospective cohort study. Data collection included demographic, clinical and laboratory parameters. Predictors of mortality were analyzed with Mann-Whitney U test. Results: Eight patients were included in our analysis. Three patients died in the ED (37.5%). Patients who died had significantly lower pH (7.07 vs. 7.4, p = 0.036), higher potassium (7.3 vs. 3.2 mmol/L, p = 0.036), higher calcium (1.19 vs. 0.97 mmol/L, p = 0.036), higher lactate (10.9 vs. 3.5 mmol/L, p = 0.036) and higher PaCO2 (57.2 vs. 28 mmHg, p = 0.036) at admission compared to those who did not die. Conclusions: The risk of heat stroke due to climate change-induced heat stress and the consequent thermoregulatory disruption may now be significant in temperate climate zones where it was not previously present. Standardization of differential diagnostic and therapeutic procedures could reduce mortality. pH, potassium, lactate and calcium levels may play an important role in predicting the outcome of heat stroke.

Background: Red blood cell (RBC) transfusions are essential for many patients admitted to emergency departments (ED). However, accessibility to red cell transfusions is often limited, especially in low-income countries such as Haiti. This article aims to determine the proportion of patients requiring emergency transfusion, transfused patients' characteristics, as well as the response rate and timeliness of blood product delivery for requests made. Methods: A retrospective study was conducted among all patients with RBC transfusion indications from January to June 2022 at the ED of Mirebalais Teaching Hospital. The parameters studied included transfusion indications, pre-transfusion hemoglobin levels, and delay from prescription to transfusion. Results: During the study period, 3993 patients received treatment in the ED. The proportion of patients requiring RBCs was 7.69%, including 145 males and 117 females, with a median age of 43 [30–56] years. Only 21.7% of these patients received a transfusion. The average pre-transfusion hemoglobin level was 4.75 ± 1.68 g/dL. The most common transfusion's indications were infection/sepsis (36.74%), trauma (23.48%), and cancer (21.57%). The median time delay from prescription to transfusion was 2.37 [0.97–4.93] days. The study identified significant associations between RBC transfusion probability and patient factors like hemoglobin levels, patient disposition, urgency of RBC request, and length of stay. Conclusion: RBC transfusion requests are frequent in the ED of Mirebalais Teaching Hospital, with a relatively high transfusion delay. Further studies on the relevance of RBC requests and ways to reduce delay from prescription to transfusion would be beneficial to improve this situation. [ABSTRACT FROM AUTHOR]

Personal and family history of suicidal thoughts and behaviors (PSH and FSH, respectively) are significant risk factors associated with suicides. Research is limited in automatic identification of such data from clinical notes in Electronic Health Records. This study developed deep learning (DL) tools utilizing transformer models (Bio_ClinicalBERT and GatorTron) to detect PSH and FSH in clinical notes derived from three academic medical centers, and compared their performance with a rule-based natural language processing tool. For detecting PSH, the rule-based approach obtained an F1-score of 0.75 ± 0.07, while the Bio_ClinicalBERT and GatorTron DL tools scored 0.83 ± 0.09 and 0.84 ± 0.07, respectively. For detecting FSH, the rule-based approach achieved an F1-score of 0.69 ± 0.11, compared to 0.89 ± 0.10 for Bio_ClinicalBERT and 0.92 ± 0.07 for GatorTron. Across sites, the DL tools identified more than 80% of patients at elevated risk for suicide who remain undiagnosed and untreated. [ABSTRACT FROM AUTHOR]

The American Society of Anesthesiologist's Physical Status (ASA-PS) classification system assesses comorbidities before sedation and analgesia, but inconsistencies among raters have hindered its objective use. This study aimed to develop natural language processing (NLP) models to classify ASA-PS using pre-anesthesia evaluation summaries, comparing their performance to human physicians. Data from 717,389 surgical cases in a tertiary hospital (October 2004–May 2023) was split into training, tuning, and test datasets. Board-certified anesthesiologists created reference labels for tuning and test datasets. The NLP models, including ClinicalBigBird, BioClinicalBERT, and Generative Pretrained Transformer 4, were validated against anesthesiologists. The ClinicalBigBird model achieved an area under the receiver operating characteristic curve of 0.915. It outperformed board-certified anesthesiologists with a specificity of 0.901 vs. 0.897, precision of 0.732 vs. 0.715, and F1-score of 0.716 vs. 0.713 (all p <0.01). This approach will facilitate automatic and objective ASA-PS classification, thereby streamlining the clinical workflow. [ABSTRACT FROM AUTHOR]

Background: Plantar fasciitis (PF) is the most common cause of heel pain affecting both young active patients and older sedentary individuals. It most often arises as a result of degenerative changes in the proximal plantar fascia. Aim: The purpose of this study was to investigate the effect of extracorporeal shockwave on gait parameters in patients with plantar fasciitis. Design: A randomized controlled clinical trial. Setting: The outpatient physiotherapy clinic of the teaching hospital Shibin El Kom. Methods: Participants were randomly divided into two equal groups. Group (A) (study group): received extracorporeal shockwave therapy one session per week and traditional treatment (ultrasound, stretching exercises, and strengthening exercises) three sessions per week for 4 weeks. Group (B)(the control group): received traditional treatment (ultrasound, stretching exercises, and strengthening exercises) 3 sessions per week for 4 weeks. The pre- and post-treatment development of the patients was evaluated by visual analog scale (VAS) to measure pain, foot function index (FFI) to measure foot function, and Kinovea software to analyze gait parameters (stride length, stride time, walking speed, and cadence). Results: Both groups showed improvement in all study variables, but the study group showed more improvement. There was a statistically significant decrease in VAS (p = 0.001), a significant decrease in FFI (p = 0.001), a significant increase in stride length (p = 0.001), a significant decrease in stride time (p = 0.001), a significant increase in walking speed (p = 0.001), and a significant increase in cadence (p = 0.01) post-treatment compared to group (B). Conclusion: Extracorporeal shockwave treatment is regarded as a useful treatment for improving gait parameters in patients with plantar fasciitis. Clinical rehabilitation impact: Extracorporeal shockwave therapy improved gait parameters in patients with plantar fasciitis as it increases stride length, walking speed, cadence, and decreases stride time. So, it is recommended to be included in the rehabilitation program for patients with plantar fasciitis and gait disabilities. [ABSTRACT FROM AUTHOR]

Molluscum contagiosum (MC) is a common skin infection affecting children globally, including in Israel, which has a diverse population comprising mainly Jews (73.2%) and Arabs (21.1%). Despite documented disparities in various diseases between these groups, research on differences in dermatological care is scarce. This study aimed to investigate MC as a potential differentiator between Arab and Jewish children. A retrospective analysis of MC cases among children (0–18 years) from 2013 to 2022 was performed at Soroka University Medical Center, a tertiary hospital serving over a million patients. 615 patients participated in our study, with 95.2% Jewish and 4.8% Arab. Both groups showed similar characteristics in lesion quantity (P = 0.535), diameter (P = 0.341), inflammation markers, and lesion location. Additionally, management, treatment response, and outcomes were found to be similar between the two groups. In conclusion, the Arab representation in the study was disproportionately low compared to their population in the area. While Jewish patients may rely more on medical specialists, we believe Arabs may prefer self-management practices, such as the use of traditional medicine, possibly hindering effective physician-led care. Understanding such disparities could improve dermatological care by tailoring approaches to diverse populations. [ABSTRACT FROM AUTHOR]

Background: Cardiac arrest remains a global health issue with limited data on long-term outcomes, particularly regarding recurrent cardiovascular events in patients surviving out-of-hospital cardiac arrest. (OHCA). We aimed to describe the long-term occurrence of major cardiac event defined by hospital admission for cardiovascular events or death in OHCA hospital survivors, whichever came first. Our secondary objective were to assess separately occurrence of hospital admission and death, and to identify the factors associated with major event occurrence. We hypothesized that patients surviving an OHCA has a protracted increased risk of cardiovascular events, due to both presence of the baseline conditions that lead to OHCA, and to the cardiovascular consequences of OHCA induced acute ischemia-reperfusion. Methods: Consecutive OHCA patients from three hospitals of Sudden Death Expertise Center (SDEC) Registry, discharged alive from 2011 to 2015 were included. Long-term follow-up data were obtained using national inter-regime health insurance information system (SNIIRAM) database and the national French death registry. The primary endpoint was occurrence of a major event defined by hospital admission for cardiovascular events and death, whichever came first during the follow-up. The starting point of the time-to-event analysis was the date of hospital discharge. The follow-up was censored on the date of the first event. For patients without event, follow-up was censored on the date of December, 29th, 2016. Results: A total of 306 patients (mean age 57; 77% male) were analyzed and followed over a median follow-up of 3 years for hospital admission for cardiovascular event and 6 years for survival. During this period, 38% patients presented a major event. Hospital admission for cardiovascular events mostly occurred during the first year after the OHCA whereas death occurred more linearly during the all period. A previous history of chronic heart failure and coronary artery disease were independently associated with the occurrence of major event (HR 1.75, 95%CI[1.06-2.88] and HR 1.70, 95%CI[1.11-2.61], respectively), whereas post-resuscitation myocardial dysfunction, cardiogenic shock and cardiologic cause of cardiac arrest did not. Conclusion: Survivors from OHCA must to be considered at high risk of cardiovascular event occurrence whatever the etiology, mainly during the first year following the cardiac arrest and should require closed monitoring.

In this paper, we model the statistical properties of imaging exam durations using parametric probability distributions such as the Gaussian, Gamma, Weibull, lognormal, and log-logistic. We establish that in a majority of radiology procedures, the underlying distribution of exam durations is best modeled by a log-logistic distribution, while the Gaussian has the poorest fit among the candidates. Further, through illustrative examples, we show how business insights and workflow analytics can be significantly impacted by making the correct (log-logistic) versus incorrect (Gaussian) model choices.

Cerebrospinal fluid (CSF) leakages of the temporal bone may arise during mastoid surgery. The leakages can have multiple potential etiologies, for instance, using a cutting burr near the bony tegmen or monopolar electrocautery on the surface of the dura mater. In this paper, we introduced an effective and simple technique for the management of CSF leakages of the temporal bone. In a prospective case series, 36 patients (16 males and 20 females) who have had an experience of incidental or inevitable CSF otorrhea or otorhinorrhea during temporal bone surgery were selected. All patients were treated using a muscle graft in a dumbbell-shaped design through the dura defect at the Amir-Alam University Hospital between April 2005 and November 2008. The mean size of the defects was 5 mm (a range of 2–10 mm). A dumbbell-shaped autologous muscle graft was immediately successful in sealing the leakage in all patients. Only five patients (13.8%) had some evidence of leakage remaining on the day after the operation, which was subsequently resolved by conservative management in four of them (11.1%). Only one patient (2.7%) was subjected to a second operation for a new defect. Recurrence of CSF leakage or other related complications were not observed during about 7 years of follow up. A free autologous muscle graft, using the dumbbell technique through a small to moderate dura defect is an effective, easily performed, and safe method to seal iatrogenic leakages of the temporal bone.

Background: Optimal balance between macro- and microcirculation in critically ill patients is crucial for ensuring optimal organ perfusion. Nitric oxide (NO) is a regulator of vascular hemostasis and tone. The availability of NO is controlled by asymmetric dimethylarginine (ADMA), symmetric dimethylarginine (SDMA), and the availability of the NO substrates arginine and homoarginine. We investigated the changes in plasma concentrations of ADMA, SDMA, arginine, and homoarginine days 1–5 of intensive care unit (ICU) admission and the association between the change in concentration days 1–3 and 30-day all-cause mortality. Methods: Single-center cohort study of adult critically ill patients from the ICU at Copenhagen University Hospital – North Zealand. ADMA, SDMA, arginine, and homoarginine (NO-biomarkers) were measured on days 1–5. Initially, we determined the changes in NO-biomarkers days 1–5 with linear mixed models, and subsequently how the changes in NO-biomarkers days 1–3 were associated with 30-day all-cause mortality. Post-hoc we analyzed the association between plasma concentration at admission and 30-day all-cause mortality. Results: In total 567 out of 577 patients had plasma samples from days 1–5. Plasma concentrations of ADMA and arginine increased from days 1–5. SDMA concentrations increased from days 1–2, followed by a decrease from days 2–5. Concentrations of homoarginine did not change from days 1–3 but slightly increased from days 3–5. In total 512 patients were alive 3 days after ICU admission. Among these patients, a daily twofold increase in ADMA concentration from days 1–3 was associated with decreased mortality in multivariate analysis (HR 0.45; 95% CI 0.21–0.98; p = 0.046). An increase in SDMA, arginine, or homoarginine was not associated with mortality. Post-hoc we found that a twofold increase in ADMA or SDMA concentrations at admission was associated with mortality (HR 1.78; 95% CI 1.24–2.57; p = 0.0025, and HR 1.41; 95% CI 1.05–1.90; p = 0.024, respectively). Conclusions: Increasing ADMA concentrations on days 1–3 are inversely associated with mortality, however not with the same strength as high ADMA or SDMA concentrations at admission. We suggest that admission concentrations are the focus of future research on ADMA and SDMA as predictors of mortality or potential therapeutical targets in ICU patients. [ABSTRACT FROM AUTHOR]

Background: Cluster headache (CH) is a significant health concern due to its major socioeconomic consequences and most patients being refractory to conventional strategies. For treatment resistant CH, occipital nerve stimulation (ONS) is considered an effective treatment option. Whereas most patients do not adjust the amplitude of the ONS system, a subset changes the amplitude on a regular basis using their remote control, and are therefore referred to as 'voltage tuners'. Anxiety and self-control are thought to be central themes to this behavior. Research on this voltage tuning behavior could provide new insights in the use of ONS as acute attack treatment. To date, voltage tuning has not been assessed for CH. Hence this is a unique study aiming to investigate the occurrence and efficacy of voltage tuning in patients with CH and ONS. Methods: For this analysis, patients with CH who received ONS from 2020–2024, at our university medical center, were included. All patients underwent bilateral ONS implantation. Data on attack frequency, intensity and duration were collected retrospectively. Outcomes on the response, frequency, moment during the day, duration, rationale, sensation, average increase in amplitude, and efficacy of voltage tuning were collected with prospective interviews. Results: Thirty-three patients (M = 20) (42 ± 12.7 years) were included in the current analysis. At 1y follow-up, an overall response rate of 70% (23/33) was found for ONS. In total, 48% (18/33) of patients were defined as voltage tuners. Voltage tuning was performed with an average increase in amplitude of 92 (20–360)%, a frequency of 1–20 times/month and duration of 20 minutes-48 hours. Sensations of voltage tuning were described as "tingling" and/or "pinching". The rationale for voltage tuning in patients varied from prevention and ceasing to lowering the intensity and enhance control of CH attack. Conclusions: Outcomes show that voltage tuning may cease and/or terminate CH attacks and therefore raise interests in the use of ONS as acute attack treatment for patients with resistant CH treated with ONS. Future research on the occurrence and potential of voltage tuning will provide valuable insights for achieving optimal efficacy of ONS and quality of life in patients with CH. [ABSTRACT FROM AUTHOR]

Background: Myringoplasty is one of the most common surgeries performed in otology centers, with many factors influencing the success rate, including the size and site of perforation, function of the Eustachian tube, revision surgery, and expertise of the surgeons. It is well established that the perforation closure rate is lower when performed by trainee surgeons than by senior otologists. Myringoplasty performed by trainees tends to pose more iatrogenic trauma to middle ear mucosa, less gentle manipulation of ossicles, and prolonged operation time compared with operations performed by experienced surgeons, all of which might produce more damage to middle ear structures and consequently negatively affect the closure rate of TM and audiological outcome. This study aimed to assess the audiological outcomes of successfully closed perforation myringoplasty performed by a trainee under supervision. Methods: The study design was an analytic cross-sectional study of 35 patients aged between 6 and 62 years diagnosed with safe TM perforation. All patients had two audiograms, one before surgery and the other 3 months after surgery. The exclusion criteria included any case with cholesteatoma, tumor, tympanosclerosis, or ossicular erosion/fixation because this study aimed to study the sole effect of closing TM perforation without any other confounding factor. Results: The results indicate a mean hearing improvement of 12.25 dB of ABG and 10.6 dB of AC thresholds at the four frequencies of 500, 1000, 2000, and 4000 Hz. The mean of the residual ABGs at the four frequencies is 14.2 dB. There were no correlations between the amount of air conduction threshold improvement and age, gender, side of the affected ear, area of perforation, or duration of disease (p > 0.05 for all tests). Conclusion: Although the rate of perforation closure in myringoplasties performed by trainees is lower than that of experienced surgeons, the audiological outcomes of myringoplasties performed by trainees under supervision were acceptable; however, further research is recommended.

Background: Since the declaration of COVID-19 as a pandemic in 2020, its main symptoms have primarily affected the respiratory system. However, it also presents other systemic manifestations, including symptoms related to the larynx and pharynx. COVID-19 has evolved into subsequent variants, starting from the alpha variant and currently dominated by the Omicron variant, with the Delta variant being the most severe. The study aimed to elucidate the laryngo pharyngeal manifestations related to Delta and Omicron variants of COVID-19 as well as the associated risk factors. Results: This study adopted a case–control design. The data were collected from patients who attended the phoniatric outpatient clinic at Menoufia University Hospital from January to December 2022. Patients were categorized into three groups (50 patients each). Group I consisted of patients who exhibited COVID-19 Laryngo pharyngeal symptoms during the Delta wave (Group 1) and the Omicron wave (Group 2). The control group included non-COVID-19 participants. The symptoms related to the larynx and pharynx were documented. In addition, laryngoscopic and stroboscopic examinations were done. The age of individuals affected by the Delta variant was higher. Delta cases exhibited a higher rate of smoking, diabetes, hypertension, and COPD compared to Omicron cases. Additionally, Delta cases displayed greater severity. Dysphagia, dysphonia, choking attacks related to swallowing, and stridor had significant higher rate in the Delta variant compared to the Omicron variant. The Delta variant primarily exhibited unilateral vocal fold paralysis in 38% of cases, as well as bilateral vocal fold paresis and paralysis in 20% and 22% of cases, respectively. In contrast, Omicron cases predominantly showed vocal fold congestion (80% of cases). Delta cases were more prone to experiencing abnormalities in amplitude, symmetry, and periodicity. Conclusions: The Delta variant is more prone to neurologic affection of the vocal folds manifesting as paresis and paralysis, whereas the Omicron variant, which has maintained its dominance thus far, experiences milder affection, primarily manifesting as congestion. Consequently, laryngeal affection with various degrees of severity is still suspected. [ABSTRACT FROM AUTHOR]

Background: Functional endoscopic sinus surgery (FESS) is a crucial additional procedure employed in the management of chronic rhinosinusitis (CRS). It has mostly overtaken the external methods for managing CRS that do not respond to medicinal treatment. Over the years, several instruments have been created to eliminate anatomical obstructions and restore proper function in the sinus drainage pathways. The purpose of this work was to reflect on various anatomical findings after primary functional endoscopic sinus surgery and their relationship with sinus surgery revision. Methods: This is a prospective cohort study conducted on 40 participants with CRS. The Sino-Nasal Outcome Test version 22 (SNOT-22) was utilized as a measure of results and was filled out by participants both prior to and following their operation (at the 6-month and 12-month intervals). Results: There were multiple anatomical findings encountered in CRS persistence and subsequent need for revision FESS; the most common was incomplete ethmoidectomy (both anterior and posterior) 62.5% (N = 25), and the least common was misplaced antrostomy and partial or full resection of the middle turbinate 7.5% (N = 3). Preoperative total SNOT-22 scoring ranged from 42 to 86 with mean 58.83 ± 12.08, while 6-month postoperative scoring ranged from 10 to 32 with mean 21.48 ± 5.12, and 12-month postoperative scoring ranged from 15 to 37 with mean 28.83 ± 5.52. There was significant improvement (P = 0.001). The ages of patients range between 18 and 62 years. Conclusions: Several common anatomical findings are often found during revision surgeries by analysis of CT scans and endoscopic examination of participants who underwent revision FESS for recurrent or persistent CRS, and this often shows persisting anatomical features or incompletely excised cells that correspond to persistent symptoms and signs of CRS, and the most common was incomplete ethmoidectomy. Also, there was significant improvement regarding outcome measure SNOT-22, 6-month and 12-month period postoperative as contrasted with preoperative scoring. [ABSTRACT FROM AUTHOR]

Objective: During the COVID-19 pandemic, the screening approach to the diagnosis of gestational diabetes mellitus (GDM) was subject to emergency simplifications. We aimed at assessing the effectiveness of two of these temporary pandemic protocols—namely the Australian and UK, and to examine the insights they gave into the effectiveness of the more standard WHO-outlined GDM diagnosis protocol. Methods: We performed a retrospective analysis of 432 GDM patients attending the outpatient clinic at the University Hospital of Cracow, Poland throughout 2020. Results: When applying the UK criteria, 272 (63.0%) of 432 GDM cases would be missed. Women with missed-GDM by UK criteria were slightly older, had lower BMI, and had lower use of insulin. The frequency of child perinatal complications was lower in the missed GDM group (7.6% vs. 18.9%, p = 0.042) when compared to the non-missed cases group. When applying the Australian criteria, 86 of 432 (19.9%) GDM cases would be missed. Women with missed-GDM by the Australian criteria had lower BMI and less commonly used insulin than the women not missed. There were no differences in the frequency of child and maternal complications. Conclusions: Modifications proposed from the UK and Australia resulted in varying decreases and delays in GDM diagnoses, but with no apparent harm to mothers and offspring. More studies are required to investigate the impact of the simplification of GDM diagnosis on pregnancy outcomes. [ABSTRACT FROM AUTHOR]

Wastewater based epidemiology has become a widely used tool for monitoring trends of concentrations of different pathogens, most notably and widespread of SARS-CoV-2. Therefore, in 2022, also in Rhineland–Palatinate, the Ministry of Science and Health has included 16 wastewater treatment sites in a surveillance program providing biweekly samples. However, the mere viral load data is subject to strong fluctuations and has limited value for political deciders on its own. Therefore, the state of Rhineland–Palatinate has commissioned the University Medical Center at Johannes Gutenberg University Mainz to conduct a representative cohort study called SentiSurv, in which an increasing number of up to 12,000 participants have been using sensitive antigen self-tests once or twice a week to test themselves for SARS-CoV-2 and report their status. This puts the state of Rhineland–Palatinate in the fortunate position of having time series of both, the viral load in wastewater and the prevalence of SARS-CoV-2 in the population. Our main contribution is a calibration study based on the data from 2023-01-08 until 2023-10-01 where we identified a scaling factor ( 0.208 ± 0.031 ) and a delay ( 5.07 ± 2.30 days) between the virus load in wastewater, normalized by the pepper mild mottle virus (PMMoV), and the prevalence recorded in the SentiSurv study. The relation is established by fitting an epidemiological model to both time series. We show how that can be used to estimate the prevalence when the cohort data is no longer available and how to use it as a forecasting instrument several weeks ahead of time. We show that the calibration and forecasting quality and the resulting factors depend strongly on how wastewater samples are normalized. [ABSTRACT FROM AUTHOR]

Background: The objective was to compare sevoflurane, a volatile sedation agent with potential bronchodilatory properties, with propofol on respiratory mechanics in critically ill patients with COPD exacerbation. Methods: Prospective study in an ICU enrolling critically ill intubated patients with severe COPD exacerbation and comparing propofol and sevoflurane after 1:1 randomisation. Respiratory system mechanics (airway resistance, PEEPi, trapped volume, ventilatory ratio and respiratory system compliance), gas exchange, vitals, safety and outcome were measured at inclusion and then until H48. Total airway resistance change from baseline to H48 in both sevoflurane and propofol groups was the main endpoint. Results: Sixteen patients were enrolled and were sedated for 126 h(61–228) in the propofol group and 207 h(171–216) in the sevoflurane group. At baseline, airway resistance was 21.6cmH2O/l/s(19.8–21.6) in the propofol group and 20.4cmH2O/l/s(18.6–26.4) in the sevoflurane group, (p = 0.73); trapped volume was 260 ml(176–290) in the propofol group and 73 ml(35–126) in the sevoflurane group, p = 0.02. Intrinsic PEEP was 1.5cmH2O(1–3) in both groups after external PEEP optimization. There was neither early (H4) or late (H48) significant difference in airway resistance and respiratory mechanics parameters between the two groups. Conclusions: In critically ill patients intubated with COPD exacerbation, there was no significant difference in respiratory mechanics between sevoflurane and propofol from inclusion to H4 and H48.

Few published data science tools are ever translated from academia to real-world clinical settings for which they were intended. One dimension of this problem is the software engineering task of turning published academic projects into tools that are usable at the bedside. Given the complexity of the data ecosystem in large health systems, this task often represents a significant barrier to the real-world deployment of data science tools for prospective piloting and evaluation. Many information technology companies have created Machine Learning Operations (MLOps) teams to help with such tasks at scale, but the low penetration of home-grown data science tools in regular clinical practice precludes the formation of such teams in healthcare organizations. Based on experiences deploying data science tools at two large academic medical centers (Beth Israel Deaconess Medical Center, Boston, MA; Mayo Clinic, Rochester, MN), we propose a strategy to facilitate this transition from academic product to operational tool, defining the responsibilities of the principal investigator, data scientist, machine learning engineer, health system IT administrator, and clinician end-user throughout the process. We first enumerate the technical resources and stakeholders needed to prepare for model deployment. We then propose an approach to planning how the final product will work from data extraction and analysis to visualization of model outputs. Finally, we describe how the team should execute on this plan. We hope to guide health systems aiming to deploy minimum viable data science tools and realize their value in clinical practice.

Background: COVID-19-associated pulmonary fibrosis remains frequent. This study aimed to investigate pulmonary redox balance in COVID-19 ARDS patients and possible relationship with pulmonary fibrosis and long-term lung abnormalities. Methods: Baseline data, chest CT fibrosis scores, N-terminal peptide of alveolar collagen III (NT-PCP-III), transforming growth factor (TGF)-β1, superoxide dismutase (SOD), reduced glutathione (GSH), oxidized glutathione (GSSG) and malondialdehyde (MDA) in bronchoalveolar lavage fluid (BALF) were first collected and compared between SARS-CoV-2 RNA positive patients with moderate to severe ARDS (n = 65, COVID-19 ARDS) and SARS-CoV-2 RNA negative non-ARDS patients requiring mechanical ventilation (n = 63, non-ARDS). Then, correlations between fibroproliferative (NT-PCP-III and TGF-β1) and redox markers were analyzed within COVID-19 ARDS group, and comparisons between survivor and non-survivor subgroups were performed. Finally, follow-up of COVID-19 ARDS survivors was performed to analyze the relationship between pulmonary abnormalities, fibroproliferative and redox markers 3 months after discharge. Results: Compared with non-ARDS group, COVID-19 ARDS group had significantly elevated chest CT fibrosis scores (p < 0.001) and NT-PCP-III (p < 0.001), TGF-β1 (p < 0.001), GSSG (p < 0.001), and MDA (p < 0.001) concentrations on admission, while decreased SOD (p < 0.001) and GSH (p < 0.001) levels were observed in BALF. Both NT-PCP-III and TGF-β1 in BALF from COVID-19 ARDS group were directly correlated with GSSG (p < 0.001) and MDA (p < 0.001) and were inversely correlated with SOD (p < 0.001) and GSH (p < 0.001). Within COVID-19 ARDS group, non-survivors (n = 28) showed significant pulmonary fibroproliferation (p < 0.001) with more severe redox imbalance (p < 0.001) than survivors (n = 37). Furthermore, according to data from COVID-19 ARDS survivor follow-up (n = 37), radiographic residual pulmonary fibrosis and lung function impairment improved 3 months after discharge compared with discharge (p < 0.001) and were associated with early pulmonary fibroproliferation and redox imbalance (p < 0.01). Conclusions: Pulmonary redox imbalance occurring early in COVID-19 ARDS patients drives fibroproliferative response and increases the risk of death. Long-term lung abnormalities post-COVID-19 are associated with early pulmonary fibroproliferation and redox imbalance. Highlights: Altering pulmonary redox balance drives an early pulmonary fibroproliferative response in COVID-19 ARDS. Pulmonary redox imbalance and fibroproliferation increase the risk of death in COVID-19 ARDS. Approximately 60% of moderate to severe COVID-19 ARDS survivors suffer residual pulmonary fibrosis and lung function impairment 3 months after hospital discharge. Pulmonary redox imbalance and fibroproliferation affect the resolution of residual pulmonary fibrosis and recovery from lung function impairment post-COVID-19. [ABSTRACT FROM AUTHOR]

Background: Olfactory and gustatory disorders are common problems encountered during the COVID-19 pandemic with a significant impact on the patient's quality of life: The aim of this study was to assess the olfactory and gustatory functions in COVID-19 patients with correlation between them and clinical and laboratory markers. This was a cross-sectional study conducted on 63 subjects recruited from the COVID-19 clinics at Police Authority and Menoufia University hospitals. The patients were assessed using history taking, anterior rhinoscopy, endoscopic examination, computed tomography, and polymerase chain reaction (PCR) test. Olfactory functions were assessed using the alcohol threshold test. Gustatory functions were assessed using the three-drop method. The olfactory and gustatory functions were correlated with age, gender, and laboratory parameters. Also, the recovery of smell and taste disorders was correlated with our assessed laboratory markers. Results: The prevalence of olfactory dysfunction among study participants was 41 patients (65%) of the participants including 12 patients (19.1%) having mild hyposmia, 10 patients (15.8%) having moderate hyposmia, 9 patients (14.3%) having severe hyposmia, and 10 patients (15.8%) having complete anosmia. The prevalence of gustatory dysfunction among study participants was 24 patients (38.1%). Age, gender, and laboratory parameters did not show any statistically significant difference between those who experienced olfactory dysfunction or gustatory dysfunction and those who did not. However, there was a significant positive correlation between the total leucocytic count, serum level of CRP, and serum level of D-dimer and the degree of olfactory dysfunction (0.049, 0.03, and 0.02, respectively). There was a nonsignificant correlation between recovery of olfactory and gustatory dysfunction and laboratory markers. Conclusion: Olfactory and gustatory dysfunction are established clinical presentations among COVID-19-positive patients. The laboratory markers had no correlation with the incidence of these dysfunctions or their recovery. However, TLC, serum CRP, and serum D-dimer had a significant positive correlation with the severity of olfactory dysfunction. [ABSTRACT FROM AUTHOR]

Background: Patient Reported Outcomes Measures (PROMs) are being used increasingly to measure health problems in stroke clinical practice. However, the implementation of these PROMs in routine stroke care is still in its infancy. To understand the value of PROMs used in ischemic stroke care, we explored the patients' experience with PROMs and with the consultation at routine post-discharge follow-up after stroke. Methods: In this prospective mixed methods study, patients with ischemic stroke completed an evaluation questionnaire about the use of PROMs and about their consultation in two Dutch hospitals. Additionally, telephone interviews were held to gain in-depth information about their experience with PROMs. Results: In total, 63 patients completed the evaluation questionnaire of which 10 patients were also interviewed. Most patients (82.2–96.6%) found completing the PROMs to be feasible and relevant. Half the patients (49.2–51.6%) considered the PROMs useful for the consultation and most patients (87.3–96.8%) reported the consultation as a positive experience. Completing the PROMs provided 51.6% of the patients with insight into their stroke-related problems. Almost 75% of the patients found the PROMs useful in giving the healthcare provider greater insight, and 60% reported discussing the PROM results during the consultation. Interviewed patients reported the added value of PROMs, particularly when arranging further care, in gaining a broader insight into the problems, and in ensuring all important topics were discussed during the consultation. Conclusions: Completing PROMs appears to be feasible for patients with stroke attending post-discharge consultation; the vast majority of patients experienced added value for themselves or the healthcare provider. We recommend that healthcare providers discuss the PROM results with their patients to improve the value of PROMs for the patient. This could also improve the willingness to complete PROMs in the future. [ABSTRACT FROM AUTHOR]

Background: The FROM-16 is a generic family quality of life (QoL) instrument that measures the QoL impact of patients' disease on their family members/partners. The study aimed to assess the responsiveness of FROM-16 to change and determine Minimal Important Change (MIC). Methods: Responsiveness and MIC for FROM-16 were assessed prospectively with patients and their family members recruited from outpatient departments of the University Hospital Wales and University Hospital Llandough, Cardiff, United Kingdom. Patients completed the EQ-5D-3L and a global severity question (GSQ) online at baseline and at 3-month follow-up. Family members completed FROM-16 at baseline and a Global Rating of Change (GRC) in addition to FROM-16 at follow-up. Responsiveness was assessed using the distribution-based (effect size-ES, standardized response mean -SRM) and anchor-based (area under the receiver operating characteristics curve ROC-AUC) approaches and by testing hypotheses on expected correlation strength between FROM-16 change score and patient assessment tools (GSQ and EQ-5D). Cohen's criteria were used for assessing ES. The AUC ≥ 0.7 was considered a good measure of responsiveness. MIC was calculated using anchor-based (ROC analysis and adjusted predictive modelling) and distribution methods based on standard deviation (SD) and standard error of the measurement (SEM). Results: Eighty-three patients with 15 different health conditions and their relatives completed baseline and follow-up questionnaires and were included in the responsiveness analysis. The mean FROM-16 change over 3 months = 1.43 (SD = 4.98). The mean patient EQ-5D change over 3 months = −0.059 (SD = 0.14). The responsiveness analysis showed that the FROM-16 was responsive to change (ES = 0.2, SRM = 0.3; p < 0.01). The ES and SRM of FROM-16 change score ranged from small (ES = 0.2; SRM = 0.3) for the distribution-based method to large (ES = 0.8, SRM = 0.85) for anchor-based methods. The AUC value was above 0.7, indicating good responsiveness. There was a significant positive correlation between the FROM-16 change scores and the patient's disease severity change scores (p < 0.001). The MIC analysis was based on data from 100 family members of 100 patients. The MIC value of 4 was suggested for FROM-16. Conclusions: The results of this study confirm the longitudinal validity of FROM-16 which refers to the degree to which an instrument is able to measure change in the construct to be measured. The results yield a MIC value of 4 for FROM-16. These psychometric attributes of the FROM-16 instrument are useful in both clinical research as well as clinical practice. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this study was to explore the relationships between single-nucleotide polymorphisms (SNPs) of crucial molecules in the cGAS-STING signalling pathway and the susceptibility to, induction chemotherapy response of, and prognosis of acute myeloid leukaemia (AML) in Chinese patients. Methods: Thirteen SNPs of crucial molecules in the cGAS-STING signalling pathway were genotyped in 262 AML patients using the Sequenom MassARRAY system. The associations of SNPs with susceptibility, and induction chemotherapy response were analysed using the chi-square test or Fisher's exact test and univariate binary logistic regression, the connection of SNPs with prognosis of AML was analysed using the log-rank test, and Kaplan–Meier curves were applied for survival estimation. Results: In our study, gene polymorphisms of cGAS-STING signalling pathway molecules could be vitally associated with AML. In the recessive model, the cGAS rs311678 gene polymorphism could be closely related to AML susceptibility (CC vs. TT + TC, odds ratio (OR) = 0.480, 95% confidence interval (CI) = 0.260–0.889, p = 0.020). Moreover, IKKA rs3808917 might be associated with the WBC count, cGAS rs311678 could be associated with the bone marrow (BM) blast percentage, and NF-κB rs1056890 under codominant and recessive models could be connected with the HGB level. Patients who were STING rs7380272 TT/CT carriers was likely to have higher insensitivity to induction chemotherapy than CC carriers (TT + CT vs. CC, OR = 2.917, 95% CI = 1.073–7.929, p = 0.036). Survival analysis indicated that the IKKB rs3747811 TT genotype might be associated with decreased overall survival (OS) (p < 0.05). Conclusions: SNPs of molecules in the cGAS-STING signalling pathway could be significantly associated with AML. The cGAS rs311678 gene polymorphism could be associated with AML susceptibility, the STING rs7380272 variant might be related to induction chemotherapy response, and IKKB rs3747811 tended to be associated with AML overall survival. Moreover, IKKA rs3808917 could be associated with the WBC count, cGAS rs311678 could be associated with the BM blast percentage, and NF-κB rs1056890 might be related to the HGB level.

It is well known that health disparities exist and that a significant majority of patients who suffer disproportionately from them are lower income, non-white residents of dense, and diverse urban neighborhoods. It is our belief that factors hindering the reduction of health disparities in these neighborhoods are a lack of a framework and preparation needed to engage these communities in identifying specific health care needs. This paper describes one curricular intervention, a graduate level community engagement course, developed within an academic medical center located in an urban setting, that demonstrates promise in effecting change in the extent to which clinicians are able to engage communities and practice "neighborhood-engaged care" with the central goal of mitigating disparities.

Electronic health record (EHR) implementation has dramatically impacted all facets of radiology workflow. Many departments find themselves unprepared for the multiple issues that surface following EHR deployment and the ongoing need for workflow optimization. This paper reviews the structure and processes utilized by the team, developed at the University of Colorado Hospital to evaluate, prioritize, and implement requests for workflow repairs and improvements within the EHR. The evolution of this team as the academic hospital formed a health system with two community hospital sites is also described. This structure may serve as a useful template for others considering EHR deployment or struggling to manage radiology workflow within an existing EHR environment. [ABSTRACT FROM AUTHOR]

In medicine, the challenges faced by female faculty members who are attempting to achieve academic advancement have been well described. Various strategies have been proposed to increase academic productivity to aid the promotion of women in medicine. We propose an innovative collaboration strategy that encourages completion of an academic writing project. This strategy acknowledges the challenges inherent in achieving work-life balance and utilizes a collaborative work style with a group of peer physicians. The model is designed to encourage the completion and collation of independently prepared sections of an academic paper within a setting that emphasizes social networking and collaboration. This approach has many similarities to the construction of a quilt during a "quilting bee." [ABSTRACT FROM AUTHOR]

Cardiac magnetic resonance imaging provides high spatial resolution, enabling improved extraction of important functional and morphological features for cardiovascular disease staging. Segmentation of ventricular cavities and myocardium in cardiac cine sequencing provides a basis to quantify cardiac measures such as ejection fraction. A method is presented that curtails the expense and observer bias of manual cardiac evaluation by combining semantic segmentation and disease classification into a fully automatic processing pipeline. The initial processing element consists of a robust dilated convolutional neural network architecture for voxel-wise segmentation of the myocardium and ventricular cavities. The resulting comprehensive volumetric feature matrix captures diagnostic clinical procedure data and is utilized by the final processing element to model a cardiac pathology classifier. Our approach evaluated anonymized cardiac images from a training data set of 100 patients (4 pathology groups, 1 healthy group, 20 patients per group) examined at the University Hospital of Dijon. The top average Dice index scores achieved were 0.940, 0.886, and 0.849 for structure segmentation of the left ventricle (LV), myocardium, and right ventricle (RV), respectively. A 5-ary pathology classification accuracy of 90% was recorded on an independent test set using the trained model. Performance results demonstrate the potential for advanced machine learning methods to deliver accurate, efficient, and reproducible cardiac pathological assessment. [ABSTRACT FROM AUTHOR]

Introduction: Intracranial hematoma is the collection of blood in various intracranial spaces. Knowledge of patterns, origins, causes and outcomes of ICH conditions is important for decision-making for urgent surgical interventions such as craniotomy and hematoma evacuations. No prior study was conducted in our setup. Hence, this study aimed to assess the patterns and management outcomes of intracranial hematomas in low-resource setting and tailored our management approach at Jimma University Medical center. Methods: An institution-based prospective observational study was conducted at Jimma University Medical Center, Ethiopia, for six consecutive months from June to December 2020. Different data sources and interview methods were used and analyzed using SPSS version 24. A bivariate and multivariate logistic regression was conducted to determine the association between the variables. Results: A total of 91 eligible patients were recruited during the study period, with a mean age of 34 years. The majority of patients were males [73 (80.2%)] and more common in reproductive age groups (62.6%), from rural areas (50.5%). About 93.4% of patients reported a history of trauma, and road traffic accidents & fighting account for 63.8% of the trauma cases. Sixty-five percent of patients arrive in the hospital within 24 h. Upon presentation, there were loss of consciousness (48.4%), convulsion (11%), aspiration (9.9%) and increased ICP (12%). The majority (49.5%) of the patients had a mild head injury. The focal neurologic deficits were hemiparesis (29.7%) and hemiplegia (5.5%). Acute epidural hematoma (68.1%) was a common finding, followed by sub-acute subdural hematoma. Of the total study participants, 11% had died. All the surviving patients were accessed at 30 days after discharge and re-assessed, 66 patients had good neurologic recovery (62 upper and 4 lower good recovery), 11 patients had moderate disability (7 lower and 4 upper-moderate disabilities), two patients had a severe disability, and two patients (among those with severe disability) had died. Conclusion: Trauma was invariably the cause of intracranial hematoma, and patients with low GCS, papillary abnormalities, aspiration and increased ICP had an increased risk of dying from their illness. It is good to formulate policies to enhance injury prevention and bring about health-oriented behavioral change. [ABSTRACT FROM AUTHOR]

Background: The benefit–risk balance and optimal timing of surgery for severe infective endocarditis (IE) with ischemic or hemorrhagic strokes is unknown. The study aim was to compare the neurological outcome between patients receiving surgery or not. Methods: In a prospective register-based multicenter ICU study, patients were included if they met the following criteria: (i) left-sided IE with an indication for heart surgery; (ii) with cerebral complications documented by cerebral imaging before cardiac surgery; (iii) with Sequential Organ Failure Assessment score ≥ 3. Exclusion criteria were isolated right-sided IE, in-hospital acquired IE and patients with cerebral complications only after cardiac surgery. In the primary analysis, the prognostic value of surgery in term of disability at 6 month was assessed by using a propensity score-adjusted logistic regression. Results: 192 patients were included including ischemic stroke (74.5%) and hemorrhagic lesion (15.6%): 67 (35%) had medical treatment and 125 (65%) cardiac surgery. In the propensity score-adjusted logistic regression, a favorable 6-month neurological outcome was associated with surgery (odds ratio 13.8 (95% CI 6.2–33.7). The 1-year mortality was strongly reduced with surgery in the fixed-effect propensity-adjusted Cox model (hazard ratio 0.18; 95% CI 0.11–0.27; p < 0.001). These effects remained whether the patients received delayed surgery (n = 62/125) or not and whether they were deeply comatose (Glasgow Coma Scale ≤ 10) or not. Conclusions: In critically ill IE patients with an indication for surgery and previous cerebral events, a better propensity-adjusted neurological outcome was associated with surgery compared with medical treatment.

Background: Endotracheal intubation is an essential resuscitative procedure in the emergency setting. Airway assessment parameters such as the Mallampati classification are difficult to perform in an emergency setting. As point-of-care ultrasound (POCUS) assessment of airway parameters does not require patients to perform any mandatory action, ultrasound may become the potential first-line noninvasive airway assessment tool in the emergency department (ED). The use of POCUS in the ED has not been sufficiently studied. Using POCUS in airway assessment for predicting difficult intubation may be the next step in successful airway management. Methodology: The study was an observational study conducted at the ED of the All India Institute of Medical Sciences (Rishikesh). The treating emergency physician recorded the patient history and systemic examination along with an indication for intubation. The POCUS assessment of airway parameters pre-epiglottis to epiglottic vocal cord ratio (Pre-E/E-VC), tongue thickness, hyomental distance, and distance from skin to the hyoid bone was performed by the study investigator. During laryngoscopy, Cormack-Lehane (CL) grading was assessed. The data was entered and analyzed. Results: Seventy patients who required intubation in the ED were enrolled in the study. Among the study population, 48.6%, 28.6%, 14.3%, 1.4%, and 7.1% were classified with the following CL grading: 1, 2a, 2b, 3a, and 3b, respectively. At a cutoff of ≥ 1.86, Pre-E/E-VC predicts difficult laryngoscopy (AUC 0.835) with a sensitivity of 83% and a specificity of 94%. At a cutoff of ≥ 5.98 cm, tongue thickness predicts difficult laryngoscopy (AUC 0.78) with a sensitivity of 83% and a specificity of 88%. At a cutoff of hyomental distance ≤ 6 cm, it predicts difficult laryngoscopy with a sensitivity of 83% and a specificity of 88%. All parameters can act as a promising tool for predicting difficult laryngoscopy, with the single best parameter being Pre-E/E-VC. Conclusion: Assessment of the airway with POCUS may be helpful to the emergency physician when the clinical airway assessment parameters fail to predict difficult laryngoscopy as most patients requiring intubation are uncooperative. Assessment of the parameters in our study Pre-E/E-VC, tongue thickness, and hyomental distance can act as a promising tool for predicting difficult laryngoscopy in the emergency scenario.

Transesophageal echocardiography (TEE) imaging is a vital tool used in the evaluation of complex cardiac pathology and the management of cardiac surgery patients. A key limitation to the application of deep learning strategies to intraoperative and intraprocedural TEE data is the complexity and unstructured nature of these images. In the present study, we developed a deep learning-based, multi-category TEE view classification model that can be used to add structure to intraoperative and intraprocedural TEE imaging data. More specifically, we trained a convolutional neural network (CNN) to predict standardized TEE views using labeled intraoperative and intraprocedural TEE videos from Cedars-Sinai Medical Center (CSMC). We externally validated our model on intraoperative TEE videos from Stanford University Medical Center (SUMC). Accuracy of our model was high across all labeled views. The highest performance was achieved for the Trans-Gastric Left Ventricular Short Axis View (area under the receiver operating curve [AUC] = 0.971 at CSMC, 0.957 at SUMC), the Mid-Esophageal Long Axis View (AUC = 0.954 at CSMC, 0.905 at SUMC), the Mid-Esophageal Aortic Valve Short Axis View (AUC = 0.946 at CSMC, 0.898 at SUMC), and the Mid-Esophageal 4-Chamber View (AUC = 0.939 at CSMC, 0.902 at SUMC). Ultimately, we demonstrate that our deep learning model can accurately classify standardized TEE views, which will facilitate further downstream deep learning analyses for intraoperative and intraprocedural TEE imaging.

Background: Pulmonary involvement is still regarded as a common cause of morbidity in Polymyositis/Dermatomyositis. Interstitial lung disease can result in potentially fatal consequences such as ventilatory failure, secondary pulmonary arterial hypertension, or cor pulmonale. Early diagnosis of interstitial lung disease is hence a top priority in Polymyositis/Dermatomyositis patients. Krebs von den Lungen-6 is a transmembrane mucoprotein that has recently been identified as a promising marker for interstitial lung disease diagnosis and progression. As a result, it is regarded as a powerful predictor of interstitial lung disease severity. Thirty polymyositis/dermatomyocitis patients were enrolled in this study. Thirty age and sex matched healthy individuals were selected as control group. Cutaneous Dermatomyositis Disease Area Severity index(CDASI) was used for evaluation of skin severity, KL6 was measured using Elisa kit, High-resolution computed tomography, pulmonary function tests were made. Results: Sixteen female and 14 male patients had a mean age of 41.64–8.02 and amedian of the disease duration of 4 years. Fifteen patients (50%) had normal readings on High-resolution computed tomography of the chest HRCT chest, while the other half had significant HRCT chest findings. KL-6 concentrations were seen to be higher in Polymyositis/Dermatomyositis patients mainly those with ILD (mean ± SD 38.66 ± 22.98), compared to the control group (Mean ± S 589.04 ± 409) and in patients without ILD (Mean ± SD 86.70 ± 8.99), (p < 0.001). KL-6 serum concentrations were shown to have a significant connection with the HRCT score (r = 0.803, P < 0.001). Forced vital capacity (FVC%) (r = − 0.910, P < 0.001), forced expiratory volume in 1 s (FEV1%) (r = − 0.767, P < 0.001), and FEV1/FVC% (r = − 0.228, P = 0.112) were all inversely related to KL-6 concentrations. Conclusion: Individuals with PM and DM with concomitant ILD have increased KL-6 serum concentrations in comparison to myositis individuals without ILD, denoting its potential role in diagnosis and follow up of PM/DM with ILD. Further studies are needed to discuss the role of KL6 in large sample of the patient's population, and its correlation with other organ affection rather than ILD. Also to clarify the potentiality of adding the KL6 biomarker to the guidelines of treat to target for Rheumatic diseases with lung affection and to see the effect of treatment on KL6 serum level.

Dentistry involves the use of many instruments that are sharp and deal with blood and saliva that may be contaminated with either HBV, HCV, or HIV. Professional exposure of healthcare workers (as dentists and dental students) to blood or other potentially infected biological material may cause transmission of infection to them. Transmission of infection can occur through several routes; mucosal, cutaneous, or percutaneous. Transmission of pathogens may result in an asymptomatic infection. This situation may last for weeks or months until symptoms appear. Some patients are, thus, not aware of their infectious status and may carry an asymptomatic infection when visiting a dental practice. Aim of study The objective of the current study was to detect the level of knowledge among dental students regarding the human immunodeficiency virus, hepatitis B virus, and hepatitis C virus. The attitude and risk perception of the students about the treatment of patients with these viruses were also assessed. In our study, we determined also the relationship between knowledge, attitude, and risk perception. Methodology Six hundred eighty responded students were included in this study. They were selected from all 5 years of study to form 2 equal groups (340 students in each group), group I (junior students): 1st, 2nd, and 3rd years and group II (senior students): 4th and 5th years. The questionnaires (distributed to the students) included five main parts: the sociodemographic part, the knowledge part, the attitude part, the risk perception part, and the self-evaluation part. Results (1) The correct answer score was higher in group II than in group I (58.54% and 41.46% respectively). (2) The professional attitude score was higher in group II than in group I (60.81% and 39.19% respectively). (3) The positive risk perception was higher in group II than in group I (56.20% and 43.80% respectively). Conclusion The level of knowledge plays an important role in forming attitudes and risk perceptions toward patients with HBV, HCV, and HIV. This is of concern in dentistry and other similar fields like otolaryngology. [ABSTRACT FROM AUTHOR]
