Detailed Questionnaire Research Articles

The national ambulatory medical care survey (NAMCS) at fifty: Past and future

IntroductionNAMCS, sponsored by the Centers for Disease Control and Prevention, is an annual nationally representative sample survey of visits to non-federal office-based physicians, excluding anesthesiologists, radiologists, and pathologists. NAMCS has collected physician-reported ambulatory care encounter-specific content over five decades. We assessed trends in the use of the data by the health services research community, response rates, and questionnaire changes. MethodsWe extracted all peer-reviewed journal articles using NAMCS data published between 1973 and 2020 and categorized publications into high- and low-impact groups, with high impact considered as the top 25 % of journals. We then examined the annual number of journal publications using NAMCS, data according to the year collected, by impact score groups for 50 years. We compared response rates and the information requested by NAMCS questionnaires from 1973 to the present. ResultsThere has been a significant decline in the overall use of NAMCS data by the non-federal health services research community for publication in both high and lower-impact journals. Data used for high impact publications peaked in 1998, at 87, remained high at 58 in 2008 but then sharply declined. Concurrently, there was a substantial decline in NAMCS survey response rates (highest: 80.5 % in 1975 vs. lowest: 28.8 % in 2015). These changes came in the context of increasing questionnaire complexity. ConclusionOver the last two decades, annual publication rates citing NAMCS data have declined, coincident with lower response rates and more detailed questionnaires. Nationally representative encounter-specific data verified by the clinician of record will likely have renewed value for those who develop, implement, and assess healthcare policy if response rates improve, and questionnaire review and finalization are streamlined. Though multispecialty data offer unique opportunities for comparisons, sampling a subset of clinicians, such as those providing primary care, would complement national efforts to improve access to continuous comprehensive care.

Common Genetic Factors May Play a Role in the Relationships Between Body Composition, Adipokines, and Low-Back-Pain-Related Disability

In this study, we evaluated the contribution of the putative genetic factors into the established associations between selected circulating adipokine levels, body composition measurements, and low-back-pain-related disability scores (LBP_DS). A total of 1078 individuals from 98 nuclear families (with 1 to 11 siblings per family) were examined. A detailed self-report questionnaire was used to collect LBP disability data; body composition (fat, skeletal muscle mass, and extracellular water (ECW)) was assessed using the bioimpedance method; plasma levels of adipokines were measured by ELISA. Pedigree-based statistical analysis methods were used, including family-based variance component analysis (VCA) and principal phenotype analysis (PPA), to estimate the contribution of potential genetic and environmental factors. The VCA revealed a significant additive genetic component in LBP_DS and for the selected body composition phenotypes and adipokines. The study also revealed that both adipokines (GDF-15, chemerin, and follistatin) and body composition variables (BMI, fat mass/weight, waist circumference, and ECW) were genetically correlated with LBP_DS. Next, PPA generated two synthetic phenotypes: PPCT (combining cytokines) and PPBC (combining body composition variables). There was no significant correlation between the putative genetic factors underlying the created PPs. However, each of them displayed a significant genetic correlation with LBP_DS. These findings indicate that genetic factors that are assumingly common for several adipokine variations and several body composition measurements, respectively, presumably have a pleotropic genetic influence on the LBP_DS variation, independently from one another. This, in turn, suggests that the alleged genetic factors employing pleiotropic effects on LBP_DS have a complex and probably non-overlapping composition.

Analysing the Impact of Natural Disasters, Pandemics and Other Crisis on Employment and Workforce Dynamics

This study investigates the impact of recent crises such as natural disasters and pandemics on employment and workforce dynamics using a Random Forest machine learning model. The data was collected through a detailed questionnaire analyzing various factors, including demographic information, employment status, the impact of crises, job security, coping mechanisms, and future outlook. The findings reveal that most respondents are young adults, with a higher percentage engaged in full-time or self-employment roles. Crises, notably COVID-19, led to significant financial impacts such as reduced salaries and layoffs, with many experiencing jobs in security and moderate to high stress levels. A substantial portion of the workforce transitioned to remote work, though many reported inadequate employer support. The analysis of the Random Forest model indicates a moderate performance in predicting workforce dynamics, with accuracy, precision, recall, and F1 scores highlighting the complexity of this issue. The study provides practical recommendations such as enhancing remote work infrastructure, improving financial and mental health support, and promoting workforce adaptability to mitigate the adverse effects of future crises and ensure a resilient workforce.

Cross-sectional study on urinary metal concentrations in young adult residents of Emirate of Sharjah, United Arab Emirates.

Human biomonitoring is crucial for regulatory toxicology, yet data on biomarker concentrations in the UAE are lacking. This study addresses this gap by analyzing urinary concentrations of 16 metals in UAE young adults, assessing correlations with personal characteristics, dietary patterns, and lifestyle habits. A cross-sectional pilot study was conducted among 144 randomly selected young adults (71 males and 73 females) from Sharjah, UAE, between January and March 2023. Participants provided urine samples, which were analyzed for 16 heavy metals using ICP-OES, and completed detailed questionnaires covering sociodemographic factors, lifestyle, and dietary habits. Descriptive statistics were used to summarize participant characteristics, and linear regression analysis was applied to explore associations between metal concentrations and factors such as gender, dietary habits, and exposure to environmental risks. Non-parametric tests, including the Mann-Whitney test, were used to assess differences by gender. Statistical significance was set at p < 0.05. Ethical approval was obtained, and informed consent was secured before participation. Significant findings include dietary influences on metal exposure, with rice consumption linked to higher metal concentrations. Sex differences were significant, with females showing elevated levels of arsenic, lead, and cadmium. Lifestyle factors, such as smoking and incense use, were correlated with increased barium and boron levels. This study highlights the significant role of dietary habits, especially the consumption of rice, in metal exposure among young adults in Sharjah. The findings highlight the urgent need for comprehensive human biomonitoring to understand environmental exposures and reform public health policies. The gender-specific differences in metal distribution suggest the necessity for targeted public health strategies. The study, however, is limited by its cross-sectional nature and the focus on a specific geographic area, warranting further research for broader generalizability. Future investigations, particularly on the impact of incense exposure on metal levels, are essential for developing comprehensive health interventions and preventive strategies in the UAE.

The Impact of Alpha-s1 Casein Hydrolysate On Chronic Insomnia: A Randomized, Double-Blind Controlled Trial

BackgroundAlpha-s1 casein hydrolysate (ACH; Lactium®) is recognized as a supplementary treatment to enhance sleep quality. However, limited studies utilizing objective sleep assessment tools have resulted in a lack of substantial validation. This study aimed to assess the effects of ACH on both subjective sleep assessments and objective polysomnography (PSG) recordings in a hospital-based cohort of Taiwanese individuals with chronic insomnia. MethodsIn this 4-week randomized, double-blind, placebo-controlled trial, 36 participants diagnosed with chronic insomnia were enrolled and randomly assigned to either the ACH or placebo groups. Initially, participants in the ACH group received 600 mg of ACH daily, which was reduced to 300 mg for the latter two weeks; the placebo group received maltodextrin capsules throughout the study. The study utilized polysomnography (PSG), along with detailed sleep questionnaires including the Insomnia Severity Index (ISI), Global Sleep Disorders Score (GSDS), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Hospital Anxiety and Depression Scale (HADS), to assess improvements in sleep quality and related health markers. The efficacy of the intervention was assessed through measures of sleep efficiency, stage distribution, and psychological well-being, comparing results from before to after the treatment phase. ResultsThe study demonstrated that ACH treatment notably enhanced sleep quality, evidenced by significant improvements in ISI, GSDS, PSQI, ESS, and HADS scores at both week 2 and 4 (all p-values < 0.05) compared with baseline scores. When compared to the placebo group, the ACH group experienced a marked reduction in GSDS scores over time (p = 0.045). Furthermore, PSG data revealed a significant decrease in sleep onset latency from baseline in the ACH group compared to the placebo group (p = 0.012; -7.7 ± 16.0 minutes vs. 6.1 ± 17.7 minutes for ACH and placebo groups, respectively). These results indicate that ACH treatment effectively improved sleep initiation and overall sleep quality. ConclusionACH Supplementation significantly improved sleep quality, particularly by reducing GSDS scores and sleep onset latency, demonstrating its potential as an effective intervention for chronic insomnia. Future studies with larger samples and exploration of long-term effects are needed to confirm these results.

Rasch model of teacher readiness instrument for implementing science learning based on Balinese local wisdom

Local culture has undergone significant shifts and alienations, leading to the neglect of societal values. This situation underscores the need for teachers to be well-prepared to incorporate local wisdom into science education, supporting Cultured-Based Learning. This study, conducted from January to June 2022, aimed to assess the relevance of items in a teacher readiness instrument for implementing local wisdom-based science learning in Bali. An ex post facto research design was employed to analyze the preparedness of 72 science teachers in Bali through a detailed questionnaire. The collected ordinal data were converted into an interval scale using the Method of Successive Interval (MSI) and analyzed using the Rasch Model with the Jamovi application to assess item relevance. The study's findings highlight the cognitive and emotional readiness of science teachers as being in the high category, while collegial support and instructional tools are in the low category. These results suggest that improving collegial features and instructional tools through lesson studies and workshops could enhance the integration of local wisdom into science education in Bali.

The economic and social burden of congenital thrombotic thrombocytopenic purpura (cTTP) in Italy

Background: Congenital thrombotic thrombocytopenic purpura (cTTP) is a rare genetic disorder characterized by an abnormal clotting process leading to serious health complications such as thrombocytopenia and hemolytic anemia. Despite its clinical significance, the estimated broader economic and social impacts in Italy on patients and society remain underexplored. Methods: A detailed questionnaire, developed and validated by a panel of cTTP experts, was distributed to healthcare professionals and patient associations to gather comprehensive data on the economic and social burden of cTTP in Italy. The study was focused on direct and indirect costs associated with the disease management of 15 patients with cTTP, as well as out-of-pocket expenses incurred by patients. Results: The analysis revealed that of the 15 patients diagnosed with cTTP in Italy, 60% were adults aged 40-55 years. Productivity loss and diminished quality of life dominated the economic burden of cTTP, accounting for 81.05% of total costs. Direct medical costs, while substantial, represented a smaller portion of the overall financial impact. Additionally, out-of-pocket expenses, though constituting the smallest fraction, underscored the financial contributions made by patients towards their own care management. Conclusion: The findings underscore the need for a multidisciplinary and holistic approach to cTTP management that extends beyond the clinical treatment. Addressing the economic and social implications of the disease is crucial for improving patient well-being and ensuring the sustainability of healthcare systems. The study advocates for increased awareness, research, and access to care for cTTP patients, highlighting the importance of comprehensive support networks to mitigate the disease’s broader societal impacts, estimated to be around 2 million euro for 15 patients in 10 years.

44 Spotting the clotting: a 3-year national surveillance study of paediatric pulmonary thromboembolism

Abstract Background Pulmonary thromboembolism (PE) is a rare event in the paediatric population but can be acutely life-threatening and result in chronic complications. Awareness of contemporary patterns of clinical presentation, diagnostic modalities, and management may aid clinicians in ensuring that patients are promptly identified and treated. Objectives To describe the risk factors, symptoms, diagnostic modalities, therapeutic interventions, and short-term outcomes in paediatric patients (neonate up to 18 years) with PE through national surveillance. Design/Methods Between January 2020 and December 2022, monthly surveillance was conducted with over 2,800 paediatricians and sub-specialists through the Canadian Paediatric Surveillance Program. Voluntary reporting of cases meeting a standardized definition of PE was followed up with a detailed questionnaire. Results 58 confirmed cases were reported; 33 (57%) were females age 15 to 18 years. Detailed information was available for 31 (53%) of 58 cases. At least 1 risk factor was identified in 28 (90%) cases and 12 (39%) patients had 2 or more risk factors. The most common risk factors were oral contraceptive use (n=10 of 31; 32%) and obesity (n=9 of 31; 29%). Presentation was symptomatic in 28 (90%) cases; 24 (77%) patients presented with 2 or more symptoms. The most common symptoms were chest pain (n=18; 58%), dyspnea (n=13; 42%) and tachycardia (n=13; 42%). The most common diagnostic modality utilized was computed tomography pulmonary angiography (n=25; 81%). Initiation of systemic anticoagulation was reported for 24 (77%) of 31 cases; thrombolysis and surgical interventions were uncommon (&amp;lt; 5 cases). Treatment complications were common (n=8; 29%). Mortality was reported, but in fewer than 5 cases. Conclusion PE in children often presents with non-specific symptoms, but usually occurs in patients with known risk factors. Clinicians should maintain a high index of suspicion in symptomatic patients, particularly those with risk factors and in cases when other diagnoses that may explain symptoms have been excluded. Anticoagulation is the mainstay of treatment; complications can occur. Prompt recognition and management presumably reduce morbidity and mortality, but this cannot be inferred from our data.

46 Micronutrient deficiencies in children and youth with autism spectrum disorder: Findings from a national surveillance study

Abstract Background Children and youth with autism spectrum disorder (ASD) may be at risk of micronutrient deficiencies secondary to feeding problems such as limited dietary repertoire and high-frequency single food intake. The epidemiology of micronutrient deficiencies in the paediatric ASD population has not been studied. Objectives To determine minimum incidence, clinical characteristics, and health care utilization for four micronutrient deficiencies in children and youth with ASD in Canada: (1) vitamin A deficiency/xerophthalmia, (2) scurvy, (3) severe, symptomatic vitamin D deficiency, and (4) severe iron-deficiency anemia. Design/Methods We conducted a study via the Canadian Paediatric Surveillance Program, an active, population-based surveillance platform, between January 2020 and December 2022. More than 2,500 paediatricians and paediatric subspecialists were asked, monthly, to report cases of children and youth &amp;lt;18 years of age with ASD and one or more of the micronutrient deficiencies under surveillance. Case information was obtained via a detailed clinical questionnaire. Descriptive statistics were used to summarize the data. For average yearly minimum incidence estimates, we used case counts over the 3 year surveillance period, 2021 census data and recent ASD prevalence estimates (2% of children/youth aged 1 to 17 years living in private dwellings in Canada). Results Twenty-seven children and youth met the case definition (most male; median age 7.7 years, range 1.8–14.9 years). Multiple deficiencies were diagnosed concurrently in 9/27 (33%). Minimum incidence, per 100,000 children and youth with ASD per year, was 5.1 for scurvy (17 diagnoses); 3.0 for severe iron deficiency anemia (10 diagnoses); 2.1 for severe, symptomatic vitamin D deficiency (7 diagnoses); and &amp;lt;1 for vitamin A deficiency/xerophthalmia (&amp;lt;5 diagnoses). Restricted diet/limited food repertoire, attributed to the patient, was universal (27/27). Number of different foods in the patient’s diet was &amp;lt;10 in nearly all (20/23, 87%). Most patients were non-verbal (19/27, 70%) and of normal weight (18/26, 69%). Two-thirds (18/27, 67%) were admitted to hospital (median duration 8 days, range 3–32 days). One-third (9/27, 33%) underwent an invasive procedure as part of their diagnostic workup. Conclusion This surveillance study represents the first population-level examination of the epidemiology of micronutrient deficiencies in children and youth with ASD. Results suggest that micronutrient deficiencies in ASD are rare but clinically important, leading not infrequently to hospital admission and invasive investigations. Clinical characteristics of cases should inform anticipatory guidance and prevention efforts tailored to the paediatric ASD population.

Impact of proprioceptive cervical dizziness in chronic neck pain syndromes on gait and stance during active head-turn challenges.

An earlier observational study described selected patients with acute neck pain syndrome, who experienced short bursts of cervical vertigo elicited by rapid head movements. The current study on a larger cohort of 20 patients with chronic or frequently recurring neck pain syndrome and age-matched controls focused on two major questions: (1) Can head movements in subjects with exacerbations of neck pain and restrictions of neck mobility also elicit bursts of vertigo? (2) What is the impact on postural balance measured by analysis of body sway and locomotion? A detailed questionnaire was applied, posture and gait were evaluated by use of instrumented posturography-and gait analysis with and without slow or rapid horizontal head rotations in the yaw plane with and without sight/visual input. All patients reported some or frequent episodes of dizziness in the range of seconds only elicited by rapid, not by slow head movements. Postural sway in patients was unremarkable in undisturbed conditions without head movements, but specifically increased by rapid but not slow head turns. The latter is best explained by the lack of continuous control of velocity and amplitude of saccadic head movements. Gait analysis revealed a slowed and cautious gait pattern already at undisturbed condition that was even exaggerated during rapid head turns. These observations demonstrate that chronic or recurrent neck pain is associated with episodic experiences of dizziness and above results in both chronic and episodic alterations of stance and gait that resemble those described for patients with phobic postural vertigo/persistent postural perceptual dizziness, a functional gait disorder.

The impact of war situation on endometriosis patients: Evaluating physical and mental health outcomes.

To investigate the impact of war situation on physical functioning, mental health status, and disease manifestations among endometriosis patients. Questionnaire-based study analyzing physical and psychosocial well-being. The study includes 50 endometriosis patients at Sheba Medical Center who completed a detailed questionnaire before and after the onset of the October 7, 2023, War in Israel. Significant deterioration in physical and mental health after the onset of war (pain score 6 vs 7; p < 0.001). Although having a first-degree relative affected by the war was associated with health deterioration (OR, 5.44; p = 0.02), similar pattern of health status aggregation was observed also in a subgroup of 19 women without family involvement, suggesting the general war situation as a likely cause. Starting new anti-anxiety or antidepressant medications and psychological therapy had a protective effect (OR, 0.21; p = 0.05). War situation exacerbates endometriosis symptoms, highlighting the importance of early psychological interventions to mitigate negative impacts.

From Consoles to Classrooms: Preliminary Insights About Pre-Service Teachers and Video Games

Integrating video games into the classroom is a promising way to enhance learning experiences, as the market of serious games is expanding. European schools are investing in digital equipment, and the use of educational video games is technologically viable. Nonetheless, actual experiences of video games in class are still rare. A key gap to be explored is understanding how pre-service secondary teachers perceive and are prepared to use digital games in their future classrooms. Do they think it would enhance their teaching and their students’ learning? Do they feel prepared for it? To answer these questions, and possibly address future challenges, we conducted a comprehensive study with students at Zurich University of Teacher Education (PHZH). The research process began with the development and testing of a detailed questionnaire that focused on participants' personal gaming behaviour, preferences, and perceptions of the educational potential of video games. Key areas such as serious games, game design, gamification, game-based learning, and game culture were explored to assess the relevance and understanding of these concepts in an educational context. This paper explains the development and structure of the questionnaire as a measurement instrument as well as the underlying literature and methodological considerations. The first implementation and the preliminary survey with 48 PHZH students are presented, and the practicability and reliability of the questionnaire are evaluated. The result of the survey suggests pre-service teachers are generally positive about integrating video games and game design into the classroom, yet enthusiasm is not enough without additional support.

Pelvic myofascial pain is associated with restriction of sexual activity in women with pelvic pain: a cross-sectional study.

Background Dyspareunia and restriction of sexual activity are often reported by patients with chronic pelvic pain, but less is known about which conditions or factors contribute most to these symptoms. Methods This is a cross-sectional study of consecutive new patients who presented to a chronic pelvic pain and endometriosis referral clinic between January 2013 and December 2015. Patients completed a detailed questionnaire prior to their first visit and underwent a comprehensive standardised pelvic examination at their first visit. Patients were grouped according to description of sexual activity as 'normal activity without pain', 'normal activity but painful', 'severely restricted by pain', or 'absent due to pain.' Primary outcome was restriction of sexual activity due to pain. Multinomial logistic regression was performed with 'normal activity without pain' group as reference category and adjusted for age, depression, history of endometriosis, and pelvic myofascial pain. Results Over half of the 187 patients with chronic pelvic pain described severely restricted (n =75, 40.1%) or absent (n =21, 11.2%) sexual activity due to pain. Pelvic myofascial pain was highly prevalent in this population and pelvic myofascial tenderness score was associated with higher odds of sexual activity that was severely restricted by pain (OR 1.05, 95% CI 1.01-1.09, P =0.006) or absent due to pain (OR 1.09, 95% CI 1.04-1.13, P Conclusion Dyspareunia and sexual dysfunction are highly prevalent among patients with chronic pelvic pain, and pelvic myofascial pain is strongly associated with restriction of sexual activity due to pain.

Balancing your mind and gut: Exploring the influence of sleep and gut health on emotional well-being

BACKGROUND: The relationship between the mind, gut, and sleep is not static and requires proper harmony for optimal emotional health. Recent evidence suggests that gut health is a key player in regulating mental and physical health via bidirectional communication between the brain and gut. MATERIALS AND METHODS: A cross-sectional comparative study was undertaken on 200 participants aged 25-40 years old for two months at a tertiary care hospital. A community-based method was used to select the participants from in and around Pune. The survey was conducted online with the help of a self-designed well-structured detailed questionnaire that included a demographic profile, medical history, history of sleep pattern, gut health status, emotional well-being status about gut and sleep physiology, and lifestyle-related issues and problems was administered to all the study participants. RESULTS: A statistically significant correlation was observed between the duration of sleep; and gastrointestinal (GI) symptoms including heartburn (P=0.03) constipation (P=0.03), bloating (P=0.04), and indigestion (P=0.051). Specific GI symptoms as mentioned above were found to affect the study participants' emotional well-being significantly. Regular physical exercise demonstrated a significant correlation with an increased duration of sleep (P=0.003). Consumption of tobacco, alcohol; smoking, and consumption of stimulants like tea, coffee, and coke showed a significant effect on both the duration and quality of sleep (P=0.004). Gut and sleep disturbances were more common in north Indian subjects as compared to south Indian subjects (P=0.003). The upper socioeconomic population had more GI; sleep and emotional disturbances as compared to the lower socioeconomic study subjects (P=0.002). CONCLUSION: The relationship between sleep patterns, emotional well-being gut health is bidirectional. Prioritizing good sleep hygiene, managing stress through mindfulness or relaxation techniques, and maintaining a balanced diet that supports gut health are crucial steps in promoting overall well-being.

The Challenge of IBD-Related Arthritis Screening Questionnaires in Early and Predominantly Entheseal Phenotypes.

Inflammatory bowel disease (IBD)-related arthritis is recognized as the most prevalent extraintestinal manifestation (EIM) of IBD. The objective of this study was to determine the prevalence and characteristics of undiagnosed IBD-related arthritis and to compare two screening questionnaires, DETection of Arthritis in Inflammatory boweL diseases (DETAIL) and IBd Identification of Spondyloarthritis Questionnaire (IBIS-q), for early disease detection. Between April and October 2023, both the DETAIL and IBIS-q questionnaires were administered to consecutive IBD outpatients visiting the University Hospital of Udine, Italy. During routine gastroenterology evaluations, patients aged > 18years with Crohn's disease (CD) or ulcerative colitis (UC) were requested to complete both questionnaires. Subsequently, all patients who completed the questionnaires underwent a blinded rheumatological evaluation within 2weeks. Patients with a previous diagnosis of IBD-related SpA were then excluded. Overall, 203 patients were enrolled, of whom 26 were excluded because of a prior diagnosis of inflammatory arthritis. Among the remaining 177 patients, 10/177 (5.6%) received a new diagnosis of IBD-related arthritis. The median duration of symptoms before diagnosis was 4 (IQR 1.8-10.5) months. Imaging-confirmed enthesitis was the predominant pattern in 8 out 10 cases (80%, with 8 out 8 lacking concomitant peripheral arthritis), axial involvement in 1 out 10 cases (10%), and peripheral arthritis in 1 out 10 cases (10%). The DETAIL questionnaire exhibited higher specificity, but lower sensitivity compared to the IBIS-q, with a sensitivity of 40.0% (12.2-73.8) and specificity of 84.4% (78.0-89.6) versus a sensitivity of 70.0% (34.8-93.3) and specificity of 74.3% (66.9-80.7). Both questionnaires performed less effectively than in other studies. This study highlights a significant proportion of undiagnosed IBD-related arthritis (5.6%). Enthesitis emerged as the predominant pattern of newly diagnosed arthritis in our cohort, likely due to the recent onset of symptoms. Our study underscores the importance of entheseal involvement in early IBD-related arthritis and the importance of incorporating entheseal involvement into screening questionnaires.

Cross-sectional study on the prevalence of post-traumatic osteoarthritis in young athletes

Background. Joint traumas often cause post-traumatic osteoarthritis (PTOA), especially in young high-impact athletes. PTOA is a primary cause of early-onset osteoarthritis, yet this group has a low diagnostic rate. The goal of this cross-sectional study is to investigate how common PTOA is in youth athletes and what risk factors they face. Methods. At Dehradun’s Shri Guru Ram Rai Institute of Medical and Health Sciences, 100 athletes aged 18-35-yearold participated in the study. Sports like athletics, cricket, football, rugby, and basketball added to the participant pool. Included criteria were joint trauma; excluded were congenital joint conditions or no traumatic osteoarthritis. Data collection included clinical exams, imaging (X-rays and MRI), and a detailed questionnaire about the athlete’s past, injuries, and rehabilitation. The main objective was PTOA incidence, while secondary outcomes assessed risk factors such sport, injury severity, and trauma duration. All statistical studies utilize logistic regression and Chi-square testing, with a significance level of p &lt; 0.05. Results. PTOA affected the knee (25%), ankle (18%), and hip (8%), with a total prevalence of 35%. The majority of PTOA patients had ligament tears, mostly ACLs. Football and rugby players had a 2.5-fold increased risk of PTOA. The risk was 3.1% higher for athletes with major injuries including fractures or dislocations. The time after the event also affected PTOA; damage older than five years was more likely. Conclusion. Results demonstrate that youth athletes often have ankle and knee PTOA. Early detection, prevention, and monitoring can reduce PTOA in this group. Identifying specific therapy to reduce joint injuries’ long-term effects requires more research.

The Five Times Sit to Stand Test as a Tool to Assess Disability and Physical Capacity after Hospitalization for COVID-19

Background: Assessment of exercise tolerance should be an integral part of the follow- up of COVID-19 survivors. Objective: We aimed in this study to investigate the correlation between the 5 Times Sit to Stand Test (5STST) and the 6-Minute Walk Test (6MWT) and to determine their place in assessing exercise tolerance and disability in COVID-19 survivors. Methods: This was a cross-sectional study that included 201 survivors of COVID-19. All patients underwent a detailed medical questionnaire, assessment of disability by the Lawton scale, and sub- -maximal exercise tolerance by 6MWT and 5STST. Our study population was divided into two groups based on the Length of Hospital Stay (LHS) (&lt;10 or ≥10 days). Results: Compared with the group with a LHS &lt; 10 days, the group with prolonged LHS (≥10 days) had a significantly greater mean value of 5STST. In contrast, the mean values of 6-minute Walk Distance (6MWD) and Minimal Oxygen Saturation (MOS) were significantly lower. A significant correlation of 5STST with Lawton score (r = -0.373; p &lt; 0.0001) and 6MWD (r = -0.563; p &lt; 0.0001) was also found. Conclusion: Our results showed that the 5STST was correlated with the 6MWD and Lawton score. Hence, it could be proposed to assess physical capacity and disability, especially in patients who had a prolonged LHS for COVID-19.

Perception of normal and treatment level ejaculatory latency times in men with premature ejaculation

Abstract Background Although the normal intravaginal ejaculation latency time (NIELT) as subjectively perceived by patients with premature ejaculation (PE) and expected IELT (EIELT), which represents the individual’s expectations of what treatment for PE would achieve, are critically influential in the treatment of patients with PE, there is a significant dearth of exploratory research on NIELT and EIELT among patients with PE. Aim To explore the NIELT and EIELT of patients with PE, understand why patients with PE perceive such a long IELT as normal, and identify factors associated with EIELT. Methods We recruited both patients with PE and control subjects, and analyzed the parameters related to IELT using detailed interviews and questionnaires. Outcomes Parameters related to IELT. Results A total of 592 individuals (mean age 29.6 ± 6.2) were included in the study, comprising 466 patients with PE (mean age 28.3 ± 5.4) and 126 non-PE individuals (mean age 34.6 ± 6.5). The actual perceived intravaginal ejaculation latency time (PIELT), referring to the patient’s self-assessed IELT at baseline, as well as NIELT, and EIELT of patients with PE, were 1.0 (1.0 − 2.0), 14.0 (10.0 − 15.0), and 15.0 (10.0 − 20.0), respectively. The control group’s PIELT and EIELT were 15.0 (10.0 − 20.0) and 20.0 (15.0 − 24.3), respectively, showing statistical differences compared with the PIELT and EIELT in the PE group. In the PE group and the control group, 31.5% and 57.9% of individuals, respectively, have an EIELT greater than the average actual normal ejaculatory latency time of 15.0 minutes. Among patients with PE, 51.3% expressed a NIELT &amp;gt;10 minutes, identical to the EIELT in a higher percentage (59.4%). The control group’s EIELT is 5 minutes longer than the PE group’s EIELT. Multivariable linear regression analysis showed that age, marital status, education level, BMI, satisfaction evaluation of PIELT, PEDT score, and IIEF-6 score were not associated with EIELT; only NIELT (beta = 0.817, P &amp;lt; 0.001) and PIELT (beta = 0.056, P = 0.044) were related to EIELT. Clinical implications Sexual health care providers should be aware that patients with PE have excessively high expectations for IELT. Strengths and limitation The first study explores why patients with clinically diagnosed PE perceive long IELT as normal and examines factors associated with EIELT. Further validation is needed in different cultural contexts. Conclusion Patients with PE often have excessively high expectations regarding IELT, primarily due to their insufficient understanding of IELT.

A New Method Proposed for the Estimation of Exposure to Atmospheric Pollution through the Analysis of Black Pigments on the Lung Surface

Megacities can be considered excellent laboratories for studying the effects of the urban environment on human health. Typically, exposure to pollution is estimated according to daily or annual averages of pollutant concentrations, collected at monitoring stations, using satellite data for remote sensing of pollutant levels, considering proximity to major roads, or through personal exposure monitoring with portable sensors. However, these approaches fall short in identifying individual exposure values over a lifetime. It is well established that individuals living in large urban areas inhale atmospheric particles containing carbonaceous components, resulting in the deposition of black pigments in lung tissue, known as black carbon or anthracosis. This study aims to detail the procedures for assessing the deposition of such pigments, which serve as an estimate of an individual’s exposure to atmospheric pollution particles. Data collection involves administering detailed questionnaires and capturing lung images in the autopsy room. The analysis is based on macroscopic quantification of black pigments, supplemented by an evaluation of personal habits and the clinical histories of the individuals. This method of estimating lifetime exposure to inhaled particles provides a valuable tool for understanding the correlation between urban living and its potential health effects.
