Promotora intervention for metabolic and mental health to reduce type 2 diabetes risk: a pilot randomized controlled trial.

The objective of this study was to develop and evaluate a novel behavioral intervention (PRIME2) that integrates evidence-based approaches for reducing diabetes risk and perceived stress. We conducted a pilot randomized controlled trial of the 16-session PRIME2 intervention vs. usual care among 40 Spanish-speaking Latinx adults with prediabetes and body mass index (BMI) ≥ 25 kg/m.

Left and right ventricular power: outputs are the strongest hemodynamic correlates to allow identification of acute responders to vasodilator treatment in idiopathic pulmonary arterial hypertension.

Introduction: Despite the prognostic importance of traditionally derived measurements, the significance of right heart catheterization (RHC) remains controversial. Thus, a continued search for hemodynamic markers that define better responsive patients is required. Since, right ventricular failure is the most fatal pathway, right (RVPO) and left (LVPO) ventricular power output are parameters that could provide input for a better understanding of the hemodynamics involved in idiopathic pulmonary artery hypertension (IPAH).

[The possible clinical role of the cardiac pulmonary power in patients with primary pulmonary hypertension. Initial observations].

The heart is a muscular mechanical pump with an ability to generate both flow [cardiac output] and pressure in the systemic circulation as well in the pulmonary vascular bed. The product of flow output and systemic arterial pressure is the rate of useful work done, or cardiac power output [CP], therefore for the right ventricle and the pulmonary arterial vascular bed it will be: the product of flow output and mean pulmonary arterial pressure will be the rate of useful work done, or cardiac pulmonary power output [CPP]. Cardiac pulmonary pumping reserve capability can be defined as the maximal cardiac pulmonary power output [CPP] achieved by the right heart during maximal stimulation.

[Severe right ventricular hypertension secondary to metastatic obstruction due to hepatocarcinoma].

Right ventricular hypertension (RVH) is an entity that could be expected in various cardiopulmonary diseases. Mechanical obstruction to the right ventricle outflow tract is a cause of RVH. We present the case of a 69 year-old male with a history of hepatocarcinoma previously treated.
