Fasting triglyceride concentrations are associated with markers of lipid metabolism and glucose homeostasis in healthy, non-obese dogs in lean and overweight condition.

Serum triglyceride concentrations increase in dogs with obesity, which is typically assessed by body condition score (BCS), however little is known about changes that take place in non-obese dogs in overweight condition. Further, the associations of triglyceride levels with other markers of energy homeostasis are poorly characterised in healthy animals. The present study aimed to evaluate associations between both BCS and triglyceride concentrations with other markers of lipid and glucose metabolism in healthy, non-obese dogs, as well as to assess whether these markers change significantly in non-obese dogs with overweight as compared to their lean counterparts.

Early Alteration of Right Ventricle-Pulmonary Artery Coupling in Experimental Heart Failure With Preserved Ejection Fraction.

Background: Pulmonary hypertension and right ventricular (RV) dysfunction are major prognostic determinants in patients with heart failure with preserved ejection fraction (HFpEF). The underlying pathomechanisms remain unknown. In this context, we sought to study the pathogenesis of pulmonary hypertension and RV dysfunction in a rat model of obesity-associated HFpEF.

Factors associated with burnout among minimally invasive gynecologic surgery fellows.

Background: While burnout has been identified in half of practicing physicians, no validated questionnaires have assessed burnout among minimally invasive gynecologic surgery fellows.

Objective: This study aimed to assess factors associated with burnout among minimally invasive gynecologic surgery fellows.

Study Design: Cross-sectional online survey including the validated Copenhagen Burnout Inventory: 100 minimally invasive gynecologic surgery fellows in the United States were invited, including the classes of 2021 and 2022.

Agriculture and downstream ecosystems in Florida: an analysis of media discourse.

Environmental media discourse analysis allows researchers to explore thematic patterns in media coverage of environmental issues through qualitative observations and quantitative coding. In this paper, we review newspaper media coverage in Florida pertaining to the connections between agriculture, other non-point pollution sources, and downstream ecosystem health. We analyzed 930 articles from 2007 through 2019 to determine common patterns in how these issues are covered by Florida media, including patterns in the causes of environmental problems, potential solutions, and stakeholders mentioned.

Activation of Smad2/3 signaling by low fluid shear stress mediates artery inward remodeling.

Endothelial cell (EC) sensing of wall fluid shear stress (FSS) from blood flow governs vessel remodeling to maintain FSS at a specific magnitude or set point in healthy vessels. Low FSS triggers inward remodeling to restore normal FSS but the regulatory mechanisms are unknown. In this paper, we describe the signaling network that governs inward artery remodeling.
