2022 Canadian Cardiovascular Society Guideline for Use of GLP-1 Receptor Agonists and SGLT2 Inhibitors for Cardiorenal Risk Reduction in Adults.

Can J Cardiol 2022 Aug;38(8):1153-1167

Division of Nephrology, Department of Medicine, Ottawa Hospital, University of Ottawa, Ottawa, Ontario, Canada.

This guideline synthesizes clinical trial data supporting the role of glucagon-like peptide-1 receptor agonists and sodium-glucose co-transporter 2 inhibitors (SGLT2i) for treatment of heart failure (HF), chronic kidney disease, and for optimizing prevention of cardiorenal morbidity and mortality in patients with type 2 diabetes. It is on the basis of a companion systematic review and meta-analysis guided by a focused set of population, intervention, control, and outcomes (PICO) questions that address priority cardiorenal end points. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system and a modified Delphi process were used. Read More

Bioinspired large Stokes shift small molecular dyes for biomedical fluorescence imaging.

Sci Adv 2022 Aug 12;8(32):eabo3289. Epub 2022 Aug 12.

State Key Laboratory of Drug Research, Molecular Imaging Center, Shanghai Institute of Materia Medica, Chinese Academy of Sciences, Shanghai 201203, China.

Long Stokes shift dyes that minimize cross-talk between the excitation source and fluorescent emission to improve the signal-to-background ratio are highly desired for fluorescence imaging. However, simple small molecular dyes with large Stokes shift (more than 120 nanometers) and near-infrared (NIR) emissions have been rarely reported so far. Here, inspired by the chromophore chemical structure of fluorescent proteins, we designed and synthesized a series of styrene oxazolone dyes (SODs) with simple synthetic methods, which show NIR emissions (>650 nanometers) with long Stokes shift (ranged from 136 to 198 nanometers) and small molecular weight (<450 daltons).

The importance of biological sex in cardiac cachexia.

Am J Physiol Heart Circ Physiol 2022 Aug 12. Epub 2022 Aug 12.

Trent University, Peterborough, Ontario, Canada.

Cardiac cachexia is a catabolic muscle wasting syndrome observed in approximately 1 in 10 heart failure patients. Increased skeletal muscle atrophy leads to frailty and limits mobility which impacts quality of life, exacerbates clinical care, and is associated with higher rates of mortality. Heart failure is known to exhibit a wide range of prevalence and severity when examined across individuals of different ages and with co-morbidities related to diabetes, renal failure and pulmonary dysfunction.

Identification of two novel variants of BCS1L gene in a patient with classical GRACILE syndrome.

Nephrology (Carlton) 2022 Aug 12. Epub 2022 Aug 12.

Laboratory of Nephrology & department of Nephrology, The Affiliated Qingdao Municipal Hospital of Qingdao University, Qingdao, China.

BCS1L pathogenic variants cause widely different clinical phenotypes.

VNN1 contributes to the acute kidney injury-chronic kidney disease transition by promoting cellular senescence via affecting RB1 expression.

FASEB J 2022 Sep;36(9):e22472

Department of Nephrology, Daping Hospital, Army Medical University, Chongqing, China.

The mechanisms underlying acute kidney injury (AKI) and chronic kidney disease (CKD) progression include interstitial inflammation, cellular senescence, and oxidative stress (OS). Although vanin-1 (VNN1) plays an important role in OS, its contribution to the AKI-CKD transition remains unknown. Here, we explored the roles and mechanisms of VNN1 in the progression of the AKI-CKD transition. Read More

Food for healthier aging: power on your plate.

Crit Rev Food Sci Nutr 2022 Aug 12:1-14. Epub 2022 Aug 12.

Wolfson Wohl Translational Research Centre, University of Glasgow, Glasgow, UK.

Inflammageing is a persistent low-level inflammatory burden that accompanies age-related dysregulation of the immune system during normative aging and within the diseasome of aging. A healthy diet containing a balanced amount of macronutrients, vitamins and minerals, adequate in calories and rich in poly(phenols), has an essential role in mitigating the effects of inflammageing and extending healthspan through modulation of the activity of a range of factors. These include transcription factors, such as nuclear factor erythroid-derived 2 related factor 2 (Nrf2) and nuclear factor-κB (NF-kB), the inflammasome and the activities of the gut microbiota.

Department of Medicine, Division of Nephrology, Indiana University School of Medicine, Indianapolis, VA, Medical Center.

Uromodulin (or Tamm-Horsfall protein) is a glycoprotein uniquely produced in the kidney by tubular cells of the thick ascending limb of the loop of Henle and early distal tubules. This protein exhibits bidirectional secretion in the urine and in the renal interstitium and circulation. The role of this protein in maintaining renal and systemic homeostasis is becoming increasingly appreciated. Read More
