To evaluate whether the addition of hydrochlorothiazide (HCTZ) to intravenous furosemide is a safe and effective strategy for improving diuretic response in acute heart failure (AHF).A prospective, double-blind, placebo-controlled trial, including patients with AHF randomized receive HCTZ or placebo an regimen. The coprimary endpoints were changes body weight patient-reported dyspnoea 72 h after randomization. Secondary outcomes included metrics mortality/rehospitalizations at 30 90 days....

Obesity poses a global health challenge, demanding deeper understanding of adipose tissue (AT) and its mitochondria. This study describes the role mitochondrial protein Methylation-controlled J (MCJ/DnaJC15) in orchestrating brown (BAT) thermogenesis. Here we show how MCJ expression decreases during obesity, as evident human mouse samples. MCJKO mice, even without UCP1, fundamental thermogenic protein, exhibit elevated BAT Electron microscopy unveils changes morphology resembling activation....

Pulmonary hypertension (PH) can affect both pulmonary arterial tree and cardiac function, often leading to right heart failure death. Despite the urgency, lack of understanding has limited development effective therapeutic strategies. Our research reveals that MCJ modulates mitochondrial response chronic hypoxia. levels elevate under hypoxic conditions, as in lungs patients affected by COPD, mice exposed hypoxia, myocardium from pigs subjected ventricular (RV) overload. The absence preserves...

Stress-activated p38 kinases control a plethora of functions, and their dysregulation has been linked to the development steatosis, obesity, immune disorders, cancer. Therefore, they have identified as potential targets for novel therapeutic strategies. There are four family members (p38α, p38β, p38γ, p38δ) that activated by MKK3 MKK6. Here, we demonstrate lack MKK6 reduces lifespan in mice. Longitudinal study cardiac function KO mice showed young develop hypertrophy which progresses...

Background: Patients requiring home-based palliative care have advanced complex illnesses with functional limitations and decline. This retrospective study reviewed caregiver administration of subcutaneous (SQ) medications fluids when symptom control could not be achieved using the oral route. Methods: Medical records from September 1, 2017 to February 28, 2018 were for 272 consecutive patients who received SQ or at a program. We analyzed clinical characteristics caregivers, administered,...

Skeletal muscle has gained recognition as an endocrine organ releasing myokines upon contraction during physical exercise. These exert both local and pleiotropic health benefits, underscoring the crucial role of function in countering obesity contributing to overall positive effects exercise on health. Here, we found that activates p38γ, increasing locomotor activity through secretion interleukin-15 (IL-15). IL-15 signals motor cortex, stimulating activity. This activation leading increase...
