The BioCaPPE (Biomarkers of Prostate Cancer/Prevention and Environment) study is a multicentre prospective observational cohort designed to identify biomarkers associated with prostate cancer (PCa) risk that may be modifiable through lifestyle factors. This paper describes the cohort, along with the data and bio-samples available for future studies in PCa risk assessment.
Canadian men at risk of PCa were enrolled based on one of two criteria (1) negative first prostate biopsy within 6 months from enrolment (Group 1); or (2) a prostate-specific antigen (PSA) blood level between 2.5 and 10 ng/mL without prior prostate biopsy (Group 2). At baseline, blood samples and comprehensive data were collected. PCa incidence and lifestyle factors were updated for all participants over 2 years, with extended follow-up for those who provided additional consent.
Recruitment was conducted across four health centres in Quebec, Canada. A total of 2053 men were enrolled—1499 in Group 1 and 554 in Group 2. All participants completed the initial visit, which included collection of medical and family history, anthropometric measurements, demographic information, dietary and alcohol intake, physical activity, tobacco use, medication use, and quality of life assessments, and candidate biomarker measurements. At the 2-year mark, 7.2% of participants had developed PCa; this figure has since increased to 15.3% (median follow-up: 6.1 years). Additionally, 84% (n=1718) consented to ongoing annual follow-up.
This large, prospective cohort of men at risk of PCa offers valuable resources for risk stratification and primary prevention. The BioCaPPE biosamples and data are available to support the identification of lifestyle-related biomarkers associated with PCa risk in this population.

Obsessive-compulsive disorder (OCD) is characterised by obsessive thoughts and compulsive actions. These obsessive-compulsive symptoms (OCS) are subclinical manifestations that do not meet the full diagnostic criteria for OCD and are associated with anxiety, depression and lower quality of life (QoL). Medical students are vulnerable to developing OCS due to stress in medical school. This study assessed OCS prevalence and its association with the mental well-being and QoL of medical students in Egypt.
A nationwide cross-sectional study was conducted across 15 Egyptian medical schools. Using convenience sampling, 1850 students participated by completing a self-administered questionnaire that used validated scales. We assessed OCS with the Obsessive-Compulsive Inventory-Revised (OCI-R) using a screening cut-off of ≥21, QoL with the Quality-of-Life Enjoyment and Satisfaction Questionnaire (Q-LES-QSF), and anxiety and depression with the 4-item Patient Health Questionnaire (PHQ-4). Descriptive statistics and logistic regression were employed.
Clinically significant OCS prevalence among medical students was 51.1%. Significant predictors for OCS included being female (adjusted OR (AOR)=1.25), attending a private university (AOR=1.64), and having personal (AOR=2.05) or combined personal and family history of mental illness (AOR=2.69). OCS presence was associated with a lower QoL score (Q-LES-QSF: 41.00 vs 43.97) and higher psychological distress score (PHQ-4: 5.93 vs 3.57) compared with students without OCS (p
OCS are prevalent among Egyptian medical students, especially females, private university attendees and those with a personal or family history of mental illness. These symptoms are associated with higher psychological distress and a lower QoL. As OCS were identified using a screening cut-off, and given the cross-sectional design, findings should be interpreted cautiously, warranting further longitudinal investigation. Universities should consider implementing mental health support, screening and awareness programmes to address these issues.
Surgical site infection (SSI) following transmetatarsal amputation (TMA) is common and associated with significant morbidity. However, there is limited evidence to guide perioperative strategies for SSI prevention in this population. A prospective, cross-sectional survey was conducted among vascular specialists. The questionnaire assessed current practice in SSI prevention for TMA, perceptions of evidence gaps, and willingness to participate in future research. Responses were analysed descriptively. Eighty-four valid responses were analysed, with 64.3% from consultant vascular surgeons and 84.5% from UK centres. Most respondents (84.5%) considered SSI after TMA to be a significant issue. The majority preferred primary closure in clean wounds (78.6%) and commonly used short-course antibiotics and interrupted sutures. Over 70% agreed no clear best practice exists, and 65.5% felt high-quality randomised trials are needed. Ninety-three percent expressed willingness to engage in future studies. Equipoise existed regarding interventions including antibiotic duration, wound adjuncts, and closure techniques. Opinion varied regarding whether TMA and major lower limb amputation should be pooled when undertaking research into SSI prevention. Current practice in SSI prevention for TMA is highly variable. This survey demonstrates broad support for rigorous trials to establish effective strategies and highlights the feasibility of future research in this area.
While adverse childhood experiences (ACEs) have been consistently linked to poorer cognitive outcomes in later life, far less is known about ACEs’ contribution to dementia and cognitive ageing risk in low-income and middle-income countries (LMICs), despite their growing and disproportionate share of global Alzheimer’s disease and related dementias (ADRD) burden. This study aimed to systematically review existing evidence on the association between individual ACEs and cognitive outcomes among adults aged 40 years and older in LMIC settings.
Systematic review and narrative synthesis.
We searched Medline, Embase, PsycINFO and CINAHL from the inception of each database to January 2026.
Observational studies examining the association between individual ACEs and cognitive outcomes among adults aged 40 and older in LMICs.
Two reviewers independently screened each record, assessed risk of bias using the Joanna Briggs Institute critical appraisal tool and extracted data. Results were illustrated using descriptive forest plots and a narrative synthesis.
Our systematic review included 14 studies, primarily from upper-middle-income countries, that assessed the relationship between individual ACEs and cognitive impairment (n=4) and function (n=10). 10 studies reported significant associations between ACEs and poorer cognitive function and increased risk of cognitive impairment. No study assessed the association between ACEs and ADRD. Parental death, neglect and mental health issues in the family showed consistent associations with cognitive outcomes, whereas experiencing hunger and poor health in childhood showed inconsistent associations.
Our review corroborated evidence from high-income countries that exposure to ACEs is associated with a long-term risk of poorer cognitive outcomes among older populations in LMICs. However, the available literature remains limited, with most studies originating from upper-middle-income countries, few examining cognitive impairment and none assessing ADRD. These findings underscore substantial gaps in knowledge and highlight the need for research across diverse LMIC settings to clarify the role of broader psychosocial and contextual childhood experiences in shaping cognitive ageing and dementia risk.

To assess the level of alarm fatigue among intensive care unit (ICU), cardiac care unit (CCU) and emergency room (ER) nurses, identify associated demographic and occupational factors, determine the most frequent sources of alarms and evaluate nurses’ psychological reactions to alarms.
A cross-sectional, descriptive–analytical study.
ICUs, CCUs and ERs of six public teaching hospitals affiliated with Tehran and Kashan Universities of Medical Sciences in Iran.
Using a multistage stratified random sampling method, 285 nurses were approached, of whom 260 completed and returned the questionnaires (response rate: 91%). Participants were registered nurses with at least a bachelor’s degree or higher and 3 months of experience in ICUs, CCUs or ERs.
The primary outcome was the level of alarm fatigue measured using the validated Nurses’ Alarm Fatigue Questionnaire. Secondary outcomes included factors associated with alarm fatigue and nurses’ reported psychological responses to frequent alarms.
The mean score of alarm fatigue was 26.4±7.9, indicating a moderate level. After adjusting for confounders and hospital-level clustering using multivariable mixed-effects regression, higher monthly income was significantly associated with lower alarm fatigue (β=–0.15, p=0.03), and nurses working rotational shifts reported significantly higher fatigue compared with those with fixed shifts (β=0.18, p=0.02). Other demographic and occupational factors were not significant. Reported psychological reactions to alarms included indifference (14%), irritability (18%) and anxiety/stress (15%).
ICU, CCU and ER nurses experience a moderate level of alarm fatigue, with income and shift type as independent associated factors. The association between income and alarm fatigue may reflect the role of financial stress as an additional job demand that compounds the burden of frequent alarms, particularly in contexts where low base salaries lead nurses to rely on overtime and multiple shifts. These findings underscore the need for targeted managerial and educational interventions, including shift schedule optimisation and attention to workload-related stressors, alongside alarm prioritisation strategies. Due to the cross-sectional design, causal inferences cannot be drawn.

BackgroundTinnitus is a prevalent condition worldwide, particularly among adolescents, that has a substantial impact on quality of life, yet it remains an understudied issue.
ObjectivesThis study aims to determine the prevalence of tinnitus and its associated risk factors among Palestinian adolescents aged 15–18.
MethodsA cross-sectional study was conducted from January to March 2025. A convenience sample of participants was recruited. The study utilized the European School for the Interdisciplinary Tinnitus Research Screening Questionnaire.
ResultsA total of 1,131 participants were enrolled in the study, with 64.5% being females. The prevalence of tinnitus among the study sample was 532, representing 47% of the population. Females had a higher prevalence of tinnitus, with 370 affected (50.7%) compared to males (40.4%). Significant associations were found between tinnitus and several factors: age, positive family history of tinnitus (threefold increased risk), sensitivity to external sounds (2.7 times higher likelihood), slight hearing difficulty in noisy environments (1.7 times higher risk), pain symptoms (double the risk), and difficulty falling asleep (1.8 times higher risk). Notably, the majority of affected participants (71.5%) had never sought professional care for their tinnitus.
ConclusionAlthough Tinnitus is common among Palestinian adolescents aged 15–18 years, the majority of affected participants did not seek professional care for tinnitus. These findings highlight the importance of conducting further research to shed insight into this prevalent and neglected health priority.
To examine the association between spinal mobility, disease activity, frailty and cardiorespiratory fitness (maximal oxygen uptake (VO2max)) in patients with ankylosing spondylitis (AS).
A cross-sectional comparative study was conducted at the University of Lahore and seven government hospitals (March–August 2025) including 74 patients with AS (40–55 years, modified New York criteria) and 77 age-matched and sex-matched healthy controls. Assessments included disease activity (Bath Ankylosing Spondylitis Disease Activity Index), functional limitation (Bath Ankylosing Spondylitis Functional Index), spinal mobility (Bath Ankylosing Spondylitis Metrology Index (BASMI)), chest expansion, frailty (Fatigue, Resistance, Ambulation, Illnesses, Loss of weight scale), pulmonary function and cardiorespiratory fitness (VO2max) via symptom-limited cardiopulmonary exercise testing. Functional performance was measured with the 6 min walk test (6MWT), and physical activity with the International Physical Activity Questionnaire (IPAQ). Data were analysed using t-tests, 2 tests, correlations and regression models to examine associations between clinical measures and cardiorespiratory fitness.
Among 151 participants (74 AS, 77 controls), AS patients showed significantly reduced pulmonary function (forced expiratory volume in one second 83.5% vs 91.2%, forced vital capacity 85.1% vs 93.0%), lower VO2max (27.8 vs 33.4 mL/kg/min), impaired spinal mobility (BASMI 5.1 vs 1.2) and decreased chest expansion (2.8 vs 5.6 cm; all p2max was inversely correlated with disease activity, spinal stiffness, frailty and structural damage and positively correlated with chest expansion, 6MWT and activity levels. AS status, higher disease activity, greater spinal stiffness and reduced chest expansion independently predicted low physical activity.
AS is associated with impaired pulmonary function, reduced spinal mobility and lower cardiorespiratory fitness, with disease activity, stiffness and restricted chest expansion potentially influencing physical activity and overall functional capacity.

BackgroundSystemic lupus erythematosus (SLE) is a heterogeneous autoimmune rheumatic disease whose epidemiology and clinical prognosis vary by race and sex. Observed disparities in SLE may be partly attributable to cognitive processes in clinical decision-making, which can influence diagnostic accuracy and clinical management. We aimed to examine variation in primary care physicians’ (PCP) diagnosis and management of SLE when all content of a clinical case is identical, apart from race and sex.
MethodsWe distributed an online randomized factorial survey from 04/11/2024–06/10/2024 to PCPs across the US. Participants were presented with one of four possible SLE vignettes – Black female, White female, Black male, White male – for which all other clinical content was identical. Block randomization was used to randomly modify the race (Black/White) and sex (female/male) of the SLE “case”. Primary outcomes were correct text-based responses for SLE diagnosis at initial case presentation and after reviewing additional lab results. Secondary outcomes were participants’ review time and planned next steps (treatment, referral, tests) as a proxy for cognitive bias and certainty, respectively. We calculated descriptive statistics for all outcomes stratified by assigned randomized factor and used chi-square tests to evaluate between-group differences.
Results1031 PCPs (42.7% women, mean age 52.1 ± 12.1 years) completed the case. At initial presentation, 63.9% of participants correctly identified SLE as a differential diagnosis. An initial diagnosis of SLE significantly differed by the race and sex of the case (p Conclusion
A patient’s race and sex may influence diagnostic accuracy and clinical decision-making for SLE in primary care. The observed variation in diagnostic accuracy, which aligns with the descriptive epidemiology of SLE, highlights the need for targeted interventions to ensure equitable diagnostic processes.
This study aims to investigate the association between physical fitness and markers of cognitive function in adults aged 40 and above in Qatar.
A cross-sectional study.
The Qatar Biobank, data of 1000 adults aged 40 and above.
A population of 1000 adults aged 40 years and older was included. Available data comprised measures of physical fitness including cardiorespiratory fitness, muscular strength, body composition and physical fitness capacity, as well as cognitive function assessed through tests of short-term visual memory and psychomotor coordination.
This paper investigated the physical fitness effect on cognitive functioning through short-term visual memory and psychomotor coordination testing. Logistic regression was used to measure the association between physical fitness and cognitive functioning tests.
Our study showed that lower physical fitness capacity was significantly associated with lower psychomotor coordination in females (OR=1.57, p=0.040) and showed no significant association in males (OR=1.65, p=0.062). For short-term visual memory, the association was significant in females (OR=1.68, p=0.042) unlike in males (OR=1.58, p=0.062). Males with greater muscle strength were about half as likely to have lower psychomotor coordination (OR=0.48, p=0.04). In females, a higher body fat percentage was associated with poorer cognitive function, with each 1% increase in body fat being linked to 6% higher odds of low short-term visual memory (p=0.02) and low psychomotor coordination (p=0.006). Cardiorespiratory fitness showed no statistically significant association with short-term visual memory and psychomotor coordination level in either sex.
Our findings suggest that overall physical fitness capacity is associated with better cognitive function in Qatari adults. The relationship between specific fitness measures and cognitive function varied by sex, with muscle strength having a stronger effect for males and body composition for females. These results highlight the potential importance of maintaining physical fitness for cognitive health in adulthood.
Current research lacks a comprehensive understanding of evidence-based practice (EBP) adoption and its predictors across diverse healthcare professionals (HCPs) in the Eastern Mediterranean Region (EMR), particularly with a direct comparison between nurses and other professional groups.
This study aims to evaluate the EBP competencies, adoption levels, identified barriers, and associated predictors among nurses and other healthcare professionals (HCPs) within the EMR.
A cross-sectional, correlational, and comparative design was used. An electronic survey was distributed (April 27th–August 17th, 2023) via convenience/snowball sampling, inviting nurses, physicians, physiotherapists, dentists, and pharmacists across the EMR to complete the survey. Multivariate regression analysis and structural equation modeling (SEM) were used to identify predictors of EBP adoption.
A total of 4673 HCPs participated and reported several barriers to EBP adoption, including time constraints, difficulties in interpreting statistics, lack of authority to change practices, and insufficient equipment. Nurses had fewer postgraduate degrees but more work experience and full-time employment than other HCPs. Despite reporting more workplace EBP support, nurses read less research, had lower EBP scores and adoption propensity, and perceived greater barriers than other HCPs (p < 0.002). Multivariate regression showed the highest barrier scores in Syria/Tunisia and the lowest in the United Arab Emirates. Nurses reported significantly higher barriers compared to other HCPs (p < 0.001). Fear of Change was not a primary barrier overall, but was elevated in specific subgroups of nurses. SEM showed good fit: RMSEA = 0.077, SRMR = 0.053, CFI = 0.80, χ 2(df) = 917, p < 0.001. SEM showed that EBP adoption propensity and fear of change significantly mediate the relationship between HCPs' characteristics and EBP scores.
Despite having a positive attitude and propensity towards EBP, nurses lack the necessary knowledge and support to adopt it, and they face more barriers than other healthcare professionals. Nurses require greater support from healthcare leaders to enhance their EBP competencies and address the reported barriers. Policymakers and organizations should prioritize tailored, role-specific training and supportive structures and environments to ensure equitable and effective EBP implementation for improving patient outcomes across the EMR.

BackgroundLiver transplantation (LT) represents the life-saving treatment for advanced liver disease. We aim to investigate LT indication trends and outcomes in Saudi Arabia, following the evolution of effective therapies for hepatitis C virus (HCV) and the rising fatty liver disease prevalence.
MethodsWe retrospectively analyzed data from adult patients who underwent LT from 2011 to 2023 at a tertiary referral center in Saudi Arabia. We assessed demographics, LT indication trends, Model for End-stage Liver Disease (MELD) scores, donor type, and survival outcomes.
ResultsA total of 1,419 patients were included. The median age was 56.9 years, with 37.4% female. Living donor LT (LDLT) represented 79.8% of all transplants, and 22.0% of recipients had hepatocellular carcinoma (HCC). Metabolic dysfunction-associated steatohepatitis (MASH) was the predominant indication for LT (33.2%), followed by HCV (18.0%) and hepatitis B virus (HBV) (17.1%). Overall survival rates at 1-, 2-, 3-, 5-, and 10-years post-transplantation were 87.9%, 85.0%, 82.4%, 77.7%, and 71.3%, respectively. Hazard ratios (HR) for mortality were lower in patients with HBV compared to MASH (HR: 0.44, 95% CI: 0.28–0.69, p Conclusions
MASH represents the leading indication for LT in this large cohort, necessitating preventive strategies and early detection efforts.
The number of patients requiring wound care is increasing, placing a burden on healthcare institutions and clinicians. While negative pressure wound therapy (NPWT) use has become increasingly common, Middle East-specific wound care guidelines are limited. An in-person meeting was held in Dubai with 15 wound care experts to develop guidelines for NPWT and NPWT with instillation and dwell (NPWTi-d) use for the Middle East. A literature search was performed using PubMed, Science Direct and Cochrane Reviews. Prior to the meeting, panel members reviewed literature and existing guidelines on NPWT and/or NPWTi-d use. A wound management treatment algorithm was created. Patient and wound assessment at presentation and throughout the treatment plan was recommended. Primary closure was recommended for simple wounds, and NPWT use was suggested for complex wounds requiring wound bed preparation. NPWTi-d use was advised when wound cleansing is required, if the patient is unsuitable for surgical debridement, or if surgical debridement is delayed. When NPWTi-d is unavailable, panel members recommended NPWT. Panel members recommended NPWT for wound bed preparation and NPWTi-d when wound cleansing is needed. These recommendations provide general guidance for NPWT and NPWTi-d use and should be updated as more clinical evidence becomes available.
To estimate the prevalence of established atherosclerotic cardiovascular disease (eASCVD) and the prevalence of ASCVD high-risk patients as defined by the European Society of Cardiology (ESC) among the Egyptian population of the Prevalence and Clinical Management of Atherosclerotic Cardiovascular Diseases in Patients With Type 2 Diabetes (PACT)-Middle East and Africa study.
An observational, multicentre, cross-sectional study.
Eight secondary care centres in Egypt.
550 adult males and females who provided informed consent and had been diagnosed with type 2 diabetes mellitus (T2DM) for at least 180 days. Participants were excluded if they had participated previously in the study, had been diagnosed with T1DM, experienced mental incapacity, were unwilling to participate, had a known language barrier precluding adequate understanding or cooperation or had a known congenital heart disease or malformation.
The primary outcome was the proportion of patients with eASCVD, while the secondary outcome was the proportion of patients with T2D with high risk of ASCVD and without eASCVD.
Prevalence of eASCVD was 108/550 (19.6%, 95% CI 16.5% to 23.2%), and the prevalence of high risk for ASCVD in the population without eASCVD was 378/442 (85.5%, 95% CI 81.9% to 88.5%). Approximately 99% of the study population was categorised as ESC very high risk or high risk for CVD. On assessing utilisation of antidiabetic medications with cardiovascular benefit, only 20% were receiving sodium-glucose cotransporter-2 inhibitors, and 3% were receiving glucagon-like peptide-1 analogues.
The prevalence of eASCVD and high risk for ASCVD in Egypt is alarming, and the inadequate pharmacological control increases the ASCVD burden in the T2DM population. This calls for immediate, comprehensive action to reassess T2DM care.
Smoking is a major global health problem. It kills more than half of the users. At least 1.18 billion people smoked cigarettes every day as of 2020. Although many interventions for tobacco smoking cessation have been implemented, their effectiveness remains unclear. This study aimed to assess the long-term effectiveness of various smoking cessation interventions in adults.
We conducted a systematic review and meta-analysis of randomized controlled trials reporting long-term outcomes.
Evidence searches were conducted in the Cochrane Library, Embase, Medline-OVID, PubMed, Web of Science, and Clinicaltrials.gov. Two researchers searched until August 2023 without restrictions on country, language, or year of publication. The risk ratio (RR) for continuous abstinence was obtained through biochemical verification at measurements ≥ 6 months post-intervention. Data were extracted and assessed for quality using Risk of Bias 2. Meta-analysis was carried out using a random effects model. Subgroup analyses and meta-regression were performed to explore moderator variables. Sensitivity and publication bias analyses were also performed.
Twenty-two effect sizes from 13 studies showed that tobacco smoking cessation interventions increased continuous abstinence by 2.5 times (RR 3.52; 95% CI; 2.19–5.65). The highest ratio was in the behavioral intervention (RR 7.83) with more than 6 months of therapy (RR 10.57). The tobacco smoking cessation intervention worked better in 55–64 years (RR 7.29), especially in Asia (RR 10.08). The intervention was more effective for female respondents (RR 4.21) and combination therapy format (RR 3.82). However, meta-regression showed that differences in gender and therapy format did not significantly influence the effectiveness of tobacco smoking cessation interventions in adults (p values 0.2748 and 0.8769). Sensitivity analysis (p-value 0.0025) further strengthens the evidence of the conclusions and credibility of the findings.
Behavioral therapy lasting more than 6 months was the most successful tobacco smoking cessation intervention in respondents aged 55–64 years, especially when implemented in Asia. Although not significant, therapies delivered in combination formats, especially in women, have the potential to increase continuous abstinence for adults. These findings provide important evidence for developing effective prevention and treatment strategies for long-term smoking cessation concerning the type, format, and total of therapy.
