Objectives: The measurement of serum cardiac troponin I concentrations in dogs with a range of non-primary cardiac illnesses suggests that cardiac myocyte damage is commonplace. Dogs with primary immune-mediated haemolytic anaemia have increased serum cardiac troponin I concentrations at the time of diagnosis. However, it is unclear whether biochemical evidence of cardiac myocyte damage improves following successful treatment of anaemia.

Methods: A haematology profile was performed and serum cardiac troponin I concentrations were measured in 19 dogs with primary immune-mediated haemolytic anaemia before and after treatment.

Results: The haematocrit increased significantly (P = 0 · 0001) following treatment of primary IMHA (median pre: 0 · 13 L/L, median post: 0 · 33 L/L). The serum cardiac troponin I concentrations decreased significantly (P < 0 · 05) after treatment (median pre: 0 · 26 ng/mL, median post: 0 · 16 ng/mL).

Clinical Significance: Serum cardiac troponin I concentration decreases following successful treatment of primary immune-mediated haemolytic anaemia. The clinical and prognostic significance of serum cardiac troponin I concentrations before and after treatment in dogs with primary immune-mediated haemolytic anaemia merits further investigation.

Interleukin-34 (IL-34) was recently reported to be a new biomarker for atherosclerosis diseases, such as coronary artery disease and vascular dementia. IL-34 regulates the expression of proinflammatory cytokines (IL-17A, IL-1 and IL-6), which are classical cytokines involved in myocardial ischemia‒reperfusion (MI/R) injury. However, the exact role of IL-34 in MI/R remains unknown.

Purpose: Photobiomodulation (PBM) is a non-invasive therapeutic procedure that consists of irradiating a local area of the skin with red and near-infrared lasers or light emitting diodes (LEDs). Local PBM has been studied as a method to improve exercise performance and recovery. This review aims to evaluate the efficacy of whole-body PBM for exercise performance and recovery, comparing its findings to the established effects of localized PBM.

Circulating ANGPTL3/8 Concentrations Are Associated With an Atherogenic Lipoprotein Profile and Increased CHD Risk in Swedish Population-Based Studies.

Background: Binding of ANGPTL (angiopoietin-like protein)-3 to ANGPTL8 generates a protein complex (ANGPTL3/8) that strongly inhibits LPL (lipoprotein lipase) activity, as compared with ANGPTL3 alone, suggesting that ANGPTL3/8 concentrations are critical for the regulation of circulation lipoprotein concentrations and subsequent increased coronary heart disease (CHD) risk. To test this hypothesis in humans, we evaluated the associations of circulating free ANGPTL3 and ANGPTL3/8 complex concentrations with lipoprotein concentrations and CHD risk in 2 prospective cohort studies.

Methods: Fasting blood samples were obtained in conjunction with the baseline evaluation of 9479 subjects from 2 population-based Swedish cohorts of middle-aged men and women.

Background: To date, comprehensive data on the distribution of chronic kidney disease (CKD), the most prevalent comorbidity in diabetes, among Chinese adults with diabetes is lacking. Additionally, research gaps exist in understanding the association between CKD and cardiovascular health (CVH), an integrated indicator of lifestyle and metabolic control, within a nationwide sample of Chinese adults with diabetes.

Methods: A nationally community-based cross-sectional survey was conducted in 2018-2020.
