Tobacco Use and Second-Hand Smoke Exposure Among Athletes; Assessment by Urine Cotinine Level and Exhaled Carbon Monoxide: A Cross-Sectional Study.

Tobacco use and exposure to tobacco products remain a major public health challenge, even among athletes. This study aimed to evaluate tobacco use and second-hand smoke exposure in athletes through urinary cotinine levels and exhaled air carbon monoxide (CO) measurements. This cross-sectional study included licensed athletes who visited the sports medicine outpatient clinic of a tertiary hospital.

Iron Deficiency Anemia in Children During and After PICU Stay: Single-Center Retrospective Cohort, 2021-2022.

Objectives: The primary objective was to determine iron deficiency (ID) anemia (IDA) monitoring practices in children during PICU stay. A secondary objective was to determine the current follow-up practices for IDA after PICU discharge.

Design: Retrospective observational study of 2 years (2021-2022).

Use of CRP/lymphocyte ratio as a predictor of treatment selection and mortality in COVID-19 patients in the intensive care unit.

This study primarily aimed to examine the significance of the C-reactive protein to lymphocyte ratio (CLR), a key marker of inflammation, in relation to the disease progression and management of COVID-19 patients admitted to the intensive care unit (ICU). A total of 464 patients aged 18 years or older, diagnosed with COVID-19 and admitted to the ICU between April 1, 2021, and February 1, 2022, were included in the study. Sociodemographic, laboratory, radiological, and clinical data were collected for each patient.

Coronary Microvascular Dysfunction Years After Cessation of Anabolic Androgenic Steroid Use.

Importance: Long-term use of anabolic androgenic steroids (AASs) is associated with a high risk of left ventricular hypertrophy, heart failure with reduced systolic function, and early sudden death, with the mechanism of progression being understudied. Early and persistent impaired myocardial microcirculation could be of clinical importance and a potential underlying mechanism of frequent and early cardiac disease among individuals with AAS use and a future potential target for intervention.

Objective: To investigate coronary microcirculation by measuring myocardial flow reserve (MFR) in men with current and former AAS use compared with controls with no prior AAS use, using cardiac rubidium 82 (82Rb) positron emission tomography/computed tomography (PET/CT).
