Anemia occurs frequently in chronic heart failure (CHF) patients and is associated with increased morbidity and mortality risk. Clinical trials with recombinant human erythropoietin in patients with chronic kidney disease and concomitant structural heart disease have demonstrated beneficial effects on ventricular remodeling but variable effects on clinical outcome. Preliminary clinical trials in patients with CHF demonstrate that erythropoietin therapy is well-tolerated and associated with short-term clinical benefits. The optimum target hemoglobin, erythropoietin dosing regimen, and role of iron supplementation in patients with CHF are not known. Darbepoetin alfa is a glycosylated derivative of erythropoietin with a prolonged half-life that may allow less frequent dosing in CHF populations. Additional studies are needed to determine the safety and efficacy of long-term erythropoietic therapy in CHF patients.

Aerobic exercise prevents renal osteodystrophy via irisin-activated osteoblasts.

Renal osteodystrophy is commonly seen in patients with chronic kidney disease (CKD) due to disrupted mineral homeostasis. Given the impaired renal function in these patients, common anti-resorptive agents, including bisphosphonates, must be used with caution or even contraindicated. Therefore, an alternative therapy without renal burden to combat renal osteodystrophy is urgently needed.

Background: Nasal high flow (NHF) has been proposed to sustain high intensity exercise in people with COPD, but we have a poor understanding of its physiological effects in this clinical setting.
Research Question: What is the effect of NHF during exercise on dynamic respiratory muscle function and activation, cardiorespiratory parameters, endurance capacity, dyspnoea and leg fatigue as compared to control intervention.
Study Design And Methods: Randomized single-blind crossover trial including COPD patients.

Nasal high flow (NHF) therapy is an established form of non invasive respiratory support used in acute and chronic care. Recently, a new high flow nasal cannula with asymmetric prongs was approved for clinical use. The clinical benefits of the new cannula have not yet been defined and no evidence are available on the use of asymmetric NHF support in patient with Chronic Obstructive Pulmonary Disease (COPD).

Introduction: Home care workers (HCWs) are paid caregivers who provide support to patients with chronic conditions and functional limitations. Additionally, they provide emotional support to patients and familial support. Although several qualitative studies have been conducted on HCWs, they focused more on studying prevalently the lived experiences about the workplace violence, the end of life, stressor and resilience, during the COVID-19 pandemic or focused more in dementia and heart failure, but not on feelings and working conditions.
