Purpose: To translate, adapt, and assess the psychometric properties of the Sex After MI Knowledge Test in Iranian context (where MI is myocardial infarction).

Design And Methods: A cross-sectional descriptive survey was performed. The sample comprised 250 patients with MI. Confirmatory factor analysis was applied to extract three indicators.

Findings: The Sex After MI Knowledge Test indicated good reproducibility (Cronbach's α = .76, Intraclass correlation (ICC) = 0.729, CI = 0.7280-0.781, p < .001 ICC: Intraclass correlation). Nonnormed and normed fit indices (FI) were 0.89, and incremental and comparative FIs were 0.90. Goodness-of-fit index (GFI) and adjusted GFI were below the criteria. After a varimax rotation, the first six items of the instrument explained 58.71% of total variance.

Practice Implications: The instrument showed acceptable psychometric properties in terms of construct validity and internal consistency. The instrument might be used to stimulate conversations patients with MI regarding sexual knowledge and concerns.

There is a critical need for community engagement in the process of adopting artificial intelligence (AI) technologies in public health. Public health practitioners and researchers have historically innovated in areas like vaccination and sanitation but have been slower in adopting emerging technologies such as generative AI. However, with increasingly complex funding, programming, and research requirements, the field now faces a pivotal moment to enhance its agility and responsiveness to evolving health challenges.

Rapid accumulation of knowledge and skills by trainees in the intensive care unit assumes prior mastery of clinically relevant core physiology concepts. However, for many fellows, their foundational physiology knowledge was acquired years earlier during their preclinical medical curricula and variably reinforced during the remainder of their undergraduate and graduate medical training. We sought to assess the retention of clinically relevant pulmonary physiology knowledge among pulmonary and critical care medicine (PCCM) and critical care medicine (CCM) fellows.

Factors Relating to Sprint Swimming Performance: A Systematic Review.

Sports Med

January 2025

Aquatics Lab, Department of Physical Education and Sports, Faculty of Sport Sciences, University of Granada, Granada, Spain.

Background: Swimming performance depends on a wide variety of factors; however, the interaction between these factors and their importance varies between events. In sprint events, the characterized pacing underlines its specific development, as swimmers must achieve the highest possible speed while sustaining it to the greatest extent possible.

Objectives: The aim of this review was to identify the key factors underlying sprint swimming performance and to provide in-depth and practical evidence-based information to optimize performance.

As the Army continues to adapt to evolving mission demands and global threats, those who execute the mission - both soldiers and Department of the Army (DA) civilians - must also adapt to changing occupational demands and requirements. Occupational stress within the military community is a threat to health and wellbeing that impacts not only individual soldiers and civilian personnel, but also units, families, and the broader military community. Hardiness is an operational requirement for military success, spirituality might be a means to positively impact soldier and DA Civilian hardiness.
