Impact of COVID-19 on Sleep, Anxiety, and Depression Among Medical Call Center Staff: Insights from a January 2021 Study.

BACKGROUND The COVID-19 outbreak emerged as a dual threat, effecting both the physical and mental well-being of healthcare staff. This study aimed to evaluate sleep quality using the Pittsburgh Sleep Quality Index (PSQI), levels of anxiety and depression using the Hospital Anxiety Depression Scale (HADS), and the significant influencing factors during COVID-19 pandemic in 284 workers in a medical call center in January 2021. MATERIAL AND METHODS Out of 443 pre-hospital care providers, 284 consented to participate.

Emergency ultrasound of respiratory muscles: a promising tool for determining the outcomes of COPD exacerbations.

Background: The respiratory muscles of patients with chronic obstructive pulmonary disease (COPD) exhibit structural and functional changes that can be evaluated and monitored by ultrasonography.

Methods: This single-center, prospective study was conducted in the emergency department (ED) of a tertiary care hospital over an eight-month period (September 2020-May 2021). Diaphragmatic excursions, end-expiratory thickness, and thickening fractions, as well as right and left intercostal muscle thicknesses, of all adult subjects manifesting COPD exacerbation, were assessed.

The methylome of buccal epithelial cells is influenced by age, sex, and physiological properties.

Epigenetic modifications, particularly DNA methylation, have emerged as regulators of gene expression and are implicated in various biological processes and disease states. Understanding the factors influencing the epigenome is essential for unraveling its complexity. In this study, we aimed to identify how the methylome of buccal epithelial cells, a noninvasive and easily accessible tissue, is associated with demographic and health-related variables commonly used in clinical settings, such as age, sex, blood immune composition, hemoglobin levels, and others.

Diltiazem efficacy and CYP2D6 gene polymorphism in patients with atrial fibrillation with rapid ventricular response.

Background: Diltiazem stands out as one of the front-line drugs administered in the emergency department to achieve acute rate control in patients suffering from atrial fibrillation with rapid Ventricular Response. One of the cytochrome enzymes involved in the metabolism of diltiazem is cytochrome P450 2D6 (CYP2D6). Interindividual differences can act on drug metabolism and thus drug efficacy due to the genetic polymorphism induced by the CYP2D6 enzyme.
