Objective: To assess the prevalence of coronary risk factors in 2,463 health-care workers at the General Hospital of Mexico.
Methods: The study participants--1,620 women (65.8%) and 843 men (34.2%)--ranged in age from 16 to 65 years old. Study subjects were classified into five occupational subgroups: maintenance workers, 477 (19.4%); administrators, 697 (28.3%); physicians, 495 (20.1%); nursing staff, 559 (22.7%); and students, 235 (9.5%). For each participant, a clinical history was elicited, anthropometric determinations were done, and samples were obtained for determining blood glucose, total cholesterol, low-density lipoprotein, high-density lipoprotein, and triglyceride levels.
Results: Cholesterol levels above 6.2 mmol/L (>240 mg/dL) were found in 14.9% of the women and 14.8% of the men in the overall study group. Triglyceride levels of more than 2.25 mmol/L (>200 mg/dL) were found in 471 participants (19.1%). The prevalence of obesity was 13.5%, and high blood pressure was detected in 22.2% of study participants. Only 32.2% of subjects engaged in physical exercise one or more times per week; moreover, 32% of those surveyed smoked. The prevalence for diabetes mellitus was 6.25%. The multifactorial coronary risk index was high in 13.2% of men and 43.2% of women older than 30 years of age.
Conclusion: This study confirmed the high prevalence of risk factors for cardiovascular diseases in personnel of the General Hospital of Mexico. Because many of these risk factors are modifiable, educational efforts and preventive measures should be implemented.

Diagnostic Decision-Making Variability Between Novice and Expert Optometrists for Glaucoma: Comparative Analysis to Inform AI System Design.
JMIR Med Inform

Department of Systems Design Engineering, Faculty of Engineering, University of Waterloo, Waterloo, ON, Canada.
Background: While expert optometrists tend to rely on a deep understanding of the disease and intuitive pattern recognition, those with less experience may depend more on extensive data, comparisons, and external guidance. Understanding these variations is important for developing artificial intelligence (AI) systems that can effectively support optometrists with varying degrees of experience and minimize decision inconsistencies.
Objective: The main objective of this study is to identify and analyze the variations in diagnostic decision-making approaches between novice and expert optometrists.

The most significant progress in addressing the HIV/AIDS epidemic has been the development of antiretroviral therapy (ART). However, ensuring a high degree of treatment adherence is necessary to prevent resistance and disease progression. We conducted a cross-sectional study to evaluate adherence to ART through the calculation of the medication possession ratio (MPR) and to identify risk factors for suboptimal adherence in a cohort of HIV-positive patients receiving care at a Colombian healthcare institution across 16 cities.

Importance: Sensitivity to environmental stress and adversity may influence lung cancer risk, highlighting a critical link between psychosocial factors and cancer etiology.
Objective: To evaluate whether genetically estimated sensitivity to environmental stress and adversity is associated with lung cancer risk.
Design, Setting, And Participants: Data were obtained from a genome-wide association study identifying 37 independent genetic variants strongly associated with sensitivity to environmental stress and adversity and a cross-ancestry genome-wide meta-analysis from the International Lung Cancer Consortium.

Both DNA replication and RNA transcription utilize genomic DNA as their template, necessitating spatial and temporal separation of these processes. Conflicts between the replication and transcription machinery, termed transcription-replication conflicts (TRCs), pose a considerable risk to genome stability, a critical factor in cancer development. While several factors regulating these collisions have been identified, pinpointing primary causes remains difficult due to limited tools for direct visualization and clear interpretation.

Background: Falls on stairs are a major cause of severe injuries among older adults, with stair descent posing significantly greater risks than ascent. Variations in stair descent phenotypes may reflect differences in physical function and biomechanical stability, and their identification may prevent falls.
Aims: This study aims to classify stair descent phenotypes in older adults and investigate the biomechanical and physical functional differences between these phenotypes using hierarchical cluster analysis.
