Physician Leadership and Its Effect on Physician Burnout and Satisfaction During the COVID-19 Pandemic.

Purpose: Physician burnout is a global issue associated with low job satisfaction, decreased quality of patient care, reduced productivity, and early retirement from clinical practice. We sought to evaluate the impact of the leadership qualities of direct physician supervisors on the burnout and professional satisfaction of the physicians they supervise.

Methods: An online survey was distributed by Email to all staff physicians practicing at a large Canadian academic tertiary care hospital.

Recent Developments on the Three-Dimensional Structure of Dissolved Organic Matter: Toward a Unified Description.

Advancing a common understanding about the chemical composition, size, and three-dimensional (3D) structure of dissolved organic matter (DOM) is paramount to deciphering its impact on and involvement in environmental processes, such as the fate and transport of contaminants and carbon cycling. Traditionally, DOM has been described as a collection of solvent-separated molecules or macromolecules. More recently, DOM has been depicted as a "supramolecular assembly", a collection of individual molecules and associations of molecules held together by non-covalent interactions.

Potential Role of Photochemistry in Environmental DNA Degradation.

Given the severe loss of species richness across diverse ecosystems, there is an urgent need to assess and monitor biodiversity on a global scale. The analysis of environmental DNA (eDNA), referring to any DNA extracted from environmental samples and subsequently sequenced, is a promising method for performing such biodiversity related studies. However, a comprehensive understanding of the factors that drive distinct eDNA degradation rates under different environmental conditions is currently missing, which limits the spatiotemporal interpretations that are possible from the eDNA-based detection of species.

Aortic stiffness after living kidney donation: a systematic review and meta-analysis.

Objectives: Increased aortic stiffness measured with carotid-femoral pulse wave velocity (cf-PWV) has been associated with adverse cardiovascular outcomes. Some studies have reported increased cf-PWV in living kidney donors after nephrectomy. This review aimed to determine the effects of living kidney donation on cf-PWV, glomerular filtration rate (GFR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and their differences versus non-nephrectomised healthy individuals.

Chloronitramide anion is a decomposition product of inorganic chloramines.

Inorganic chloramines are commonly used drinking water disinfectants intended to safeguard public health and curb regulated disinfection by-product formation. However, inorganic chloramines themselves produce by-products that are poorly characterized. We report chloronitramide anion (Cl-N-NO) as a previously unidentified end product of inorganic chloramine decomposition.
