Balance between Protective vs. Exacerbating Effects of ACEIs and ARBs in Omicron Variant Infections. The spike protein on the surface of the Omicron variant has a high affinity for ACE2, making it more prone to enter cells and induce ACE2 downregulation.

Ischemia-reperfusion injury (IRI) is a common pathogenic situation that arises throughout all liver surgeries, including liver transplants. We aimed to compare the preventive effects of valsartan (VST) against valsartan + sacubitril (LCZ696) on hepatic injury caused by IRI. A total of thirty-six male Westar albino rats were split into six groups randomly: sham, IRI, VST + IRI, LCZ696 + IRI, VST, and LCZ696.

Background And Aims: Endocan has been scarcely explored in COVID-19, especially regarding its modulation by veno-venous extracorporeal membrane oxygenation (VV-ECMO), hypertension or previous renin-angiotensin-aldosterone system (RAAS) inhibitors treatment. We compared endocan and other endotheliitis markers in hospitalized COVID-19 patients and assessed their modulation by VV-ECMO, hypertension and previous RAAS inhibitors treatment.
Material And Methods: Serum endocan, intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) and E-selectin were measured in "severe" (n = 27), "critically ill" (n = 17) and "critically ill on VV-ECMO" (n = 17) COVID-19 patients at admission, days 3-4, 5-8 and weekly thereafter, and in controls (n = 23) at a single time point.

The acute response to therapeutic afterload reduction differs between heart failure with preserved (HFpEF) versus reduced ejection fraction (HFrEF), with larger left ventricular (LV) stroke work augmentation in HFrEF compared to HFpEF. This may (partially) explain the neutral effect of HFrEF-medication in HFpEF. It is unclear whether such differences in hemodynamic response persist and/or differentially trigger reverse remodeling in case of long-term afterload reduction.

Background Heart failure (HF) is commonly managed by addressing water and sodium (Na) balance, with arterial circulation playing a major role in influencing renal Na and water excretion. Recently, chloride (Cl) has been recognized as an important factor in HF, associated with volume regulation and its modulation of renin-angiotensin-aldosterone system (RAAS) activity through macula densa signaling, which impacts Na retention and neurohormonal activation. Acetazolamide, a carbonic anhydrase inhibitor, can enhance decongestion in HF by increasing urinary Na and Cl excretion when added to loop diuretics, a mechanism supported by prior studies demonstrating improved urine output and decongestion.
