Cardiopulmonary exercise testing as a prognosis-assessing tool in heart failure with preserved ejection fraction.

Aims: Patients with heart failure with preserved ejection fraction represent half of the heart failure patients nowadays, an at least steady trend due to the aging of the population. We investigated whether the parameters obtained from cardiopulmonary exercise testing (CPET) correlated with the prognosis of these patients. This prospective observational cohort study assesses the relationship between the CPET parameters peakVO and VE/VCO slope and the number of heart failure hospitalizations or cardiovascular death of these patients.

Melatonin Low-Dose for Prevention of Delirium in Critically Ill Patients: A Multi-centre, Randomized, Placebo-controlled Feasibility Trial (MELLOW).

Background: Delirium is a common and serious syndrome of acute brain dysfunction associated with negative outcomes. Melatonin may have a role in delirium prevention for critically ill adults based on data from non-critically ill patient populations. Our objective was to assess the feasibility of a multi-centre, randomized, placebo-controlled trial testing the hypothesis that low-dose melatonin prevents delirium in critically ill adults.

Vaccination After Haematopoietic Stem Cell Transplant: A Review of the Literature and Proposed Vaccination Protocol.

Haematopoietic stem cell transplantation (HCT) induces profound immunosuppression, significantly increasing susceptibility to severe infections. This review examines vaccinations' necessity, timing, and efficacy post-HCT to reduce infection-related morbidity and mortality. It aims to provide a structured protocol aligned with international and national recommendations.

The Evolving Role of Neutrophils and Neutrophil Extracellular Traps (NETs) in Obesity and Related Diseases: Recent Insights and Advances.

Obesity is a chronic, multifactorial disease characterized by persistent low-grade tissue and systemic inflammation. Fat accumulation in adipose tissue (AT) leads to stress and dysfunctional adipocytes, along with the infiltration of immune cells, which initiates and sustains inflammation. Neutrophils are the first immune cells to infiltrate AT during high-fat diet (HFD)-induced obesity.
