The mediating role of residents' wellbeing between program leadership and quality of care: A cross-sectional study.

Background: Research has shown that organizational leadership and support affect organizational outcomes in several sectors, including healthcare. However, less is known about how organizational leadership might influence the wellbeing of clinical trainees as well as the quality of their patient care practices.

Objectives: This study examined the mediating effects of burnout and engagement between program director-resident relationship quality and residents' reported quality of care, and the moderating effect of perceived departmental support.

Carrier Solvents of Electronic Nicotine Delivery Systems Alter Pulmonary Surfactant.

In late 2019, hundreds of users of electronic products that aerosolize a liquid for inhalation were hospitalized with a variety of respiratory and gastrointestinal symptoms. While some investigations have attributed the disease to the presence of vitamin E acetate in liquids that also contained tetrahydrocannabinol, some evidence suggests that chronic inhalation of two common solvents used in electronic nicotine delivery systems (ENDS), propylene glycol (PG) and vegetable glycerin (VG), can interfere with the lipid components of pulmonary surfactant and cause or exacerbate pulmonary injury. The interaction between PG, VG, and lung surfactant is not yet understood.

The largest viable aortic aneurysm.

Time has allowed us to attain new therapeutic advances in both surgical and medical fields. Nevertheless, prolonging patients' life expectancies by using these new techniques exposes physicians to challenging and exceptional medical presentations that, in the near past, were not possibly attainable and would not have naturally occurred.

Transdisciplinary interventions for environmental sustainability.

This paper presents a case study of a transdisciplinary research based on an ex-post assessment of the environmental and socio-behavioral contexts of solid waste management in Lebanese peri-urban communities. Lessons learned are compiled into the Transdisciplinary Interventions for Environmental Sustainability conceptual framework. The approach starts with building a team of researchers and non-academic partners, continues with co-creating solution-oriented knowledge, and ends by integrating and applying the produced knowledge.

Split-bolus contrast injection protocol enhances the visualization of the thoracic vasculature and reduced radiation dose during chest CT.

Objective: To investigate the visualization of mediastinal lymph nodes during thoracic CT employing a multiphasic contrast media (CM) protocol.

Methods: Institutional review board approved retrospective study consisting of 300 patients with known chest malignancy. Patients were allocated to one of two CM protocols: Protocol A, consisted of dual bolus (Phase 1:100 ml CM followed by 100 ml saline chaser) i.
