Published: December 2023

Objective To compare the performance of the diagnostic model for fall risk based on the short physical performance battery (SPPB) developed using commercial machine learning software (MLS) and binomial logistic regression analysis (BLRA). Methods We enrolled 797 out of 850 outpatients who visited the clinic between March 2016 and November 2021. Patients were categorized into the development ( n = 642) and validation ( n = 155) datasets. Age, sex, number of comorbidities, number of medications, body mass index (BMI), calf circumference (left–right average), handgrip strength (left–right average), total SPPB score, and history of falls were determined. We defined fall risk by an SPPB score of ≤6 in men and ≤9 in women. The main metrics used for evaluating the machine learning model and BLRA were the area under the curve (AUC), accuracy, precision, recall (sensitivity), specificity, and F-measure. The commercial MLS automatically calculates the parameter range of the highest contribution. Results The participants included 797 outpatients (mean age, 76.3 years; interquartile range, 73.0–81.0; 288 men). The metrics of the current diagnostic model in the commercial MLS were as follows: AUC = 0.78, accuracy = 0.74, precision = 0.46, recall (sensitivity) = 0.81, specificity = 0.71, F-measure = 0.59. The metrics of the current diagnostic model in the BLRA were as follows: AUC = 0.77, accuracy = 0.75, precision = 0.47, recall (sensitivity) = 0.67, specificity = 0.77, F-measure = 0.55. The risk factors for falls in older adult outpatients were handgrip strength, female sex, experience of falls, BMI, and calf circumference in the commercial MLS. Conclusions The diagnostic model for fall risk based on SPPB scores constructed using commercial MLS is noninferior to BLRA.

Published: December 2023

Introduction Dysphagia can affect more than 50% of stroke patients in the acute phase. Aspiration pneumonia is a serious complication that can be prevented with dysphagia screening and assessment. Measurement of tongue elevation pressure is suggested to be a useful tool in aspiration risk screening. Objective This study aimed to assess the diagnostic accuracy of maximum anterior tongue elevation strength (Pmax) in acute stroke care. Method In this prospective study, data were collected in a neurology department (stroke center) where patients formed a consecutive case series. The sample consisted of thirty stroke patients who failed an initial dysphagia screening. Patients underwent anterior tongue elevation strength measurement (index test) during bedside dysphagia assessment by a speech-language pathologist and flexible endoscopic evaluation of swallowing (reference test) by an otorhinolaryngologist on the same day. Outcome variables (index values in kPa, reference values interpreted on the penetration-aspiration scale) were used for estimating measures of diagnostic accuracy in aspiration risk screening. Results Ten patients aspirated on instrumental evaluation. At the cut-off point of ≤ 34 kPa the analysis showed 90% sensitivity, 35% specificity, 41% positive predictive value, and 88% negative predictive value. The area under the curve (AUC) for Pmax was AUC = 0.700 (95% CI [0.500–0.900]). Conclusion Although individuals with low anterior tongue elevation strength tend to have a higher risk of aspiration, this variable alone is not capable of screening aspiration in acute stroke. In combination with a thorough noninstrumental bedside examination, it might have the potential to reduce the number of false positive cases. Further studies in this area would be worthwhile.

Published: December 2023

Background: The method of epidermal closure during cleft lip repair is important to consider, as it may affect complication rates, cosmetic outcomes, and patient comfort levels. Historically, this has most commonly been performed with permanent suture that requires subsequent removal, which is not well tolerated in infants. The purpose of this study is to compare the outcomes between 2-octyl cyanoacrylate liquid with a self-adhesive polyester mesh tape (2-OPMT) and typical suture closure techniques, which to our knowledge has never previously been investigated. Methods: In nine consecutive cleft lip repairs, the epidermal closure was performed with permanent suture, and in the subsequent nine consecutive cleft lip repairs, the epidermal closure was performed with 2-OPMT. Complication rates were compared between the groups. Esthetic scar outcomes were investigated via post-operative photograph analysis utilizing the Manchester Scar Scale. Statistical significance was determined with Fischer Exact Tests and Wilcoxon Rank-Sum tests. Subsequently, scar scores for 30 cleft lip repairs performed with 2-OPMT in our practice were compared to previously reported scores in the literature for 30 cleft lip repairs performed with typical suture technique. Results: Three patients in the permanent suture group had documented scar-related complications and one patient in the 2-OPMT group had documented scar-related complications. No statistically significant difference was found in complication rates between the two groups. No statistically significant difference was found in esthetic scar scores between the two different closure techniques either within our practice or in comparison to reports in the literature. Conclusions: Overall, the use of 2-OPMT offers comparable esthetic outcomes and complication rates to the use of permanent suture in epidermal closure of cleft lip repairs.

Abstract
Background
To analyze the global burden of headache disorders in adolescents and young adults (AYAs).

Methods
Data of headache disorders in the 15–39 age groups were extracted from GBD 2019. The age-standardized rates (ASRs) of incidence, prevalence, and years lived with disability (YLDs) rate were used to describe the burden. Estimated Annual Percentage Changes (EAPCs) were used to describe the trend from 1990 to 2019.

Results
In 2019, the age-standardized incidence rate (ASIR), age-standardized prevalence rate (ASPR), and age-standardized YLDs rate (ASYR) in AYAs were 42,473.18 (95% CI: 34,836.35, 50,858.30) per 100,000, 12,566.18 (95% CI: 8542.10, 16,915.68) per 100,000 and 790.32 (95% CI: 129.56, 1786.52) per 100,000, respectively. From 1990 to 2019, the ASRs showed increasing trends, with EAPCs of 0.04 (95% CI: 0.03, 0.06), 0.05 (95% CI: 0.03, 0.07), and 0.08 (95% CI: 0.07, 0.10). Migraine accounted for 91.54% of headache-related YLDs. The burdens in females were higher than those in males, especially for ASYR. This burden was greatest in the high sociodemographic index (SDI) super region. In the temporal trend of ASIR, 127 (62.25%) countries showed upward trends, mainly distributed in East Asia, Central Asia, West Africa, and Western Latin America.

Conclusions
The burden of headache disorders in the global population aged 15–39 is severe, especially among females and in countries with high SDI. Furthermore, this burden has been steadily increasing over the past three decades. Those findings assist in implementing targeted intervention measures.
Assessing receptive verb knowledge in late talkers and autistic children: advances and cautionary tales
Authors: Horvath Sabrina , Arunachalam Sudha 
Published: December 2023

Abstract
Purpose
Using eye-tracking, we assessed the receptive verb vocabularies of age-matched late talkers and typically developing children (experiment 1) and autistic preschoolers (experiment 2). We evaluated how many verbs participants knew and how quickly they processed the linguistic prompt. Our goal is to explore how these eye-gaze measures can be operationalized to capture verb knowledge in late talkers and autistic children.

Method
Participants previewed two dynamic scenes side-by-side (e.g., “stretching” and “clapping”) and were then prompted to find the target verb's referent. Children’s eye-gaze behaviors were operationalized using established approaches in the field with modifications in consideration for the type of stimuli (dynamic scenes versus static images) and the populations included. Accuracy was calculated as a proportion of time spent looking to the target, and linguistic processing was operationalized as latency of children’s first look to the target.

Results
In experiment 1, there were no group differences in the proportion of verbs known, but late talkers required longer to demonstrate their knowledge than typically developing children. Latency was predicted by age but not language abilities. In experiment 2, autistic children’s accuracy and latency were both predicted by receptive language abilities.

Conclusion
Eye gaze can be used to assess receptive verb vocabulary in a variety of populations, but in operationalizing gaze behavior, we must account for between- and within-group differences. Bootstrapped cluster-permutation analysis is one way to create individualized measures of children’s gaze behavior, but more research is warranted using an individual differences approach with this type of analysis.

AbstractThe supernumerary kidney is the rarest of all renal anomalies, and few cases have been diagnosed and reported over the years. Supernumerary kidneys are most commonly located on the left side of the abdomen with associated pathologic conditions which include malformations of the upper urinary tract and genital tract. More importantly, it usually presents with either unusual abdominal mass or features of urinary tract infections which might pose diagnostic challenges due to infrequent occurrence. In this case report, we present a 35-year-old man with a right-sided unilateral supernumerary kidney complicated by pyelonephritis. He was treated with antibiotics, and the treatment outcome was satisfactory.

Published: December 2023

Abstract
Background
Vesicoureteral reflux (VUR) is a common condition associated with childhood urinary tract infection (UTI) that can lead to chronic renal failure and hypertension. Various anti-reflux treatments were advocated, with various degrees of morbidity and success. The purpose of this study is to analyze and compare the results of modified Gil-Vernet anti-reflux surgery and bulking agent injection in children with unilateral high-grade reflux.

Methods
The study involved 179 patients who underwent surgical interventions for primary VUR from February 2013 to September 2019. Data on baseline demographics, preoperative symptoms, radiological imaging studies, and postoperative outcomes were analyzed. Treatment goal was defined as when no VUR or downgrading was detected 6 months or later after the intervention.

Results
A total of 128 patients underwent modified Gil-Vernet anti-reflux surgery and 51 patients underwent dextranomer/hyaluronic acid (Dx/HA) injection with mean VUR grading of 4.3 in both groups (P = 0.687). The overall VUR resolution rates were significantly higher in modified anti-reflux surgery rather than Dx/HA injection (86% vs. 68%, P = 0.021). Dx/HA injection was associated with shorter operation time (21 ± 8 min vs. 57 ± 11 min, P = 0.01), and shorter hospital stay (0.34 ± 0.22 days vs. 3.50 ± 0.50 days, P < 0.001). No major complications were identified in both groups.

Conclusions
Dx/HA injection has a significantly shorter operation time, lower postoperative analgesic usage, and shorter hospital stay, modified Gil-Vernet anti-reflux surgery is associated with significantly higher VUR downgrading and resolution rates than Dx/HA injection, particularly in the higher grade VUR.
Alterations of conjunctival microbiota associated with orthokeratology lens wearing in myopic children
Authors: Zhang Ju , Lu Xiuhai , Cheng Zhiwei , Zou Dulei , Shi Weiyun , Wang Ting 
Published: December 2023

Abstract
Background
Orthokeratology (OK) lens wear increases the risk of bacterial infection, but little is known about the microbiota of the conjunctival sac in myopic children wearing OK lenses. This study aimed to investigate the changes of conjunctival microbiota in children after treatment with OK lenses using 16 S rDNA sequencing.

Methods
Twenty-eight myopic children who had been continuously wearing OK lenses for 12 to 13 months were enrolled in this prospective study. Twenty-two gender- and age-matched myopic children who had not worn OK lenses or discontinued OK lens wear at least 1 year ago were recruited as controls. Conjunctival swabs from each participant were collected for exploration of the microbiota profiles, targeting the V3–V4 regions of the 16 S rRNA gene by MiSeq sequencing. The differences in the microbial community structure and diversity were also compared between groups.

Results
The bacterial alpha diversity indices in the OK lens group were not different from those in the non-wearer group (P > 0.05, Wilcoxon test), while beta diversity examined using principle coordinate analysis of unweighted UniFrac divided the two groups into different clusters. Proteobacteria, Bacteroidetes, and Firmicutes were the abundant phyla in the conjunctival sac microbiota in both groups (P < 0.05, Mann–Whitney U test). Among children in the OK lens group, the Linear discriminant analysis Effect Size identified the compositional changes in OK lens-associated bacteria. Key functional genera such as Blautia, Parasutterella, and Muribaculum were enriched, whereas Brevundimonas, Acinetobacter, Proteus, and Agathobacter decreased significantly (P < 0.05, Mann–Whitney U test). Phylogenetic investigation of communities by reconstruction of unobserved states also showed altered bacterial metabolic pathways in OK lens-associated microbiota. Moreover, using receiver operating characteristic curves, Brevundimonas, Acinetobacter, Proteus, and Agathobacter alone (the area under the curve was all > 0.7500) or in combination (the area under the curve was 0.9058) were revealed to discriminate OK lens wearers from controls.

Conclusions
The relative abundance of the microbial community in the conjunctival sac of myopic children can alter after OK lens wear. Brevundimonas, Acinetobacter, Proteus, and Agathobacter may be candidate biomarkers to distinguish between OK lens wearers and non-wearers.

Abstract
Introduction
High quality and effective primary healthcare is a national priority in Qatar. Continuing professional development (CPD) for physicians is a cornerstone of this objective, yet little is known about physicians’ preferences or barriers to CPD participation.

Method
A needs assessment was conducted using a cross-sectional web-based survey of primary care physicians registered with the Department of Healthcare Practitioners (DHP) between March and June 2017.

Results
Two-hundred-and-eighty-one complete surveys were submitted representing physicians in both public (N = 129) and private sectors (N = 152). Physicians completed medical degrees and postgraduate training across multiple countries, and most had been practicing in Qatar for 5 years or less. ‘Activities during working hours’, ‘cost’ and ‘work commitments’ were the most common barriers. There was little consensus regarding the optimal timing of CPD activities, although public sector physicians were more likely to indicate weekend activities as a barrier to participation (30% vs. 9%). Over 90% of participants preferred traditional lectures, workshops, case-based sessions, small group and online self-paced learning as formats for CPD delivery, however alternative modes of delivery were also deemed acceptable (> 80% agreement).

Conclusion
Understanding primary care physicians’ barriers and preferences is an essential component of a larger necessitated needs assessment of CPD in primary care practitioners in Qatar. Further research is warranted to understand the underlying beliefs driving physicians’ choices and the apparent variation between those working in the public and private sectors. CPD developers should consider approaches to mitigate perceived barriers and understand preferences to maximize the quality of participation.

Published: December 2023

Abstract
Background
Symptomatic COVID-19 and Long COVID, also referred to as post-acute sequelae of SARS-CoV-2 (PASC) or post-COVID conditions, have been widely reported in young, healthy people, but their prevalence has not yet been determined in student athletes. We sought to estimate the prevalence of reported COVID-19, symptomatic COVID-19, and Long COVID in college athletes in the United States attending 18 schools from spring 2020 to fall 2021.

Methods
We developed an online survey to measure the prevalence of student athletes who tested positive for COVID-19, developed Long COVID, and did not return to their sport during the relevant time period. We surveyed a convenience sample of 18 collegiate school administrators, representing about 7,000 student athletes. Of those schools surveyed, 16 responded regarding the spring 2020 semester, and 18 responded regarding the full academic year of fall 2020 to spring 2021 (both semesters).

Results
According to the survey responses, there were 9.8% of student athletes who tested positive for COVID-19 in spring 2020 and 25.4% who tested positive in the academic year of fall 2020 to spring 2021. About 4% of student athletes who tested positive from spring 2020 to spring 2021 developed Long COVID, defined as new, recurring, or ongoing physical or mental health consequences occurring 4 or more weeks after SARS-CoV-2 infection.

Conclusions
This study highlights that Long COVID occurs among young, healthy athletes and is a real consequence of COVID-19. Understanding the prevalence of Long COVID in this population requires longer follow-up and further study.
Prenatal arsenic and mercury levels among women practicing geophagy in areas with artisanal and small-scale gold mining activities, Northwestern Tanzania
Authors: Jovine Jovina , Nyanza Elias C. , Asori Moses , Thomas Deborah SK. 
Published: December 2023

Abstract
Background
Artisanal and small-scale gold mining (ASGM) areas potentially pose increased exposure to arsenic and mercury through community contamination, occupations at gold mines, and/or geophagy when soil is locally sourced. This study examined the effects of geophagy, a deliberate soil eating practice, along with community and occupational exposures in ASGM areas on urinary arsenic and blood mercury levels among pregnant women in the Mining and Health Longitudinal Cohort in northwestern Tanzania.

Methods
Data on maternal arsenic and mercury levels were captured for 1056 pregnant women using an unprovoked morning urine samples and dried blood spots respectively. We used a step-wise generalized linear regression model to retain the most relevant covariates for the model. A generalized linear regression model with identity link function was used to predict the effect of geophagy practices on arsenic and mercury levels separately. The model was adjusted using sociodemographic correlates, including maternal age, education level, whether respondents lived in mining or non-mining area, years of residence, marital status, maternal occupation, individual partner’s education, and occupational, and socioeconomic status.

Results
In the adjusted regression model, eating soil during pregnancy increased arsenic concentration by almost 23% (β = 1.229, 95% CI: 1.094, 1.38, p < 0.001) and living in mining areas had a 21.2% (β = 1.212; 95% CI: 1.039,1.414, p = 0.014) increased risk. Geophagy significantly increased mercury levels by 13.3% (β = 1.133, 95% CI: 1.022, 1.257, p = 0.018). Living in areas with ASGM activities was associated with a 142% (β = 2.422, 95% CI: 2.111, 2.776, p < 0.0001) increase in blood mercury.

Conclusion
Geophagy practices increased urinary arsenic and blood mercury levels in pregnant women, which was especially true for arsenic when living in areas with ASGM activities. Working in mining = increased risk for blood mercury levels. Community-based environmental health policies should address reductions in occupational and community exposures, along with strategic geophagy reduction interventions.
