Different Renal Function Patterns in Patients With Acute Heart Failure: Relationship With Outcome and Congestion.

Background: The role of worsening renal function during acute heart failure (AHF) hospitalization is still debated. Very few studies have extensively evaluated the renal function (RF) trend during hospitalization by repetitive measurements.

Objectives: To investigate the prognostic relevance of different RF trajectories together with the congestion status in hospitalized patients.

Spontaneous abdominal bleeding associated with SARS-CoV-2 infection: causality or coincidence?

Authors present 6 cases of abdominal bleeding associated with COVID-19, representing 1.35% of all hospitalized COVID-19 patients and hypothesize that there could be, although not very frequently, a relationship between SARS-CoV2 and bleeding. They excluded a side effect of the low molecular weight heparin therapy that all patients underwent during the course of the disease or other possible causes.

Pulmonary arterial hypertension in systemic sclerosis: Diagnosis and treatment according to the European Society of Cardiology and European Respiratory Society 2015 guidelines.

Scleroderma (systemic sclerosis) is an autoimmune connective tissue disease which presents endothelial dysfunction and fibroblast dysregulation, resulting in vascular and fibrotic disorders. Pulmonary hypertension is frequent in patients with systemic sclerosis: the natural evolution of the disease can induce the development of different forms of pulmonary hypertension, representing one of the main causes of death. Among the different forms of pulmonary hypertension in systemic sclerosis, pulmonary arterial hypertension is the most frequent one (rate of occurrence is estimated between 7% and 12%).

Hyperglycemia and Diabetes Induced by Glucocorticoids in Nondiabetic and Diabetic Patients: Revision of Literature and Personal Considerations.

Background: Glucocorticoids are powerful and effective anti-inflammatory and immunosuppressive drugs. They have extensive use in the treatment of different diseases, even though their side effects, such as hypertension, osteoporosis and, in particular, diabetes, are well known. They can exacerbate hyperglycemia in patients with diabetes mellitus or facilitate the development of metabolic disease in apparently healthy subjects, the so-called steroid-induced diabetes mellitus.
