Collaborative registry of pulmonary hypertension in Argentina (RECOPILAR). Final analysis.

The epidemiology of pulmonary hypertension (PH), especially pulmonary arterial hypertension (PAH), has not been evaluated in our country, therefore there is no reference parameter to establishing the representativeness of this information in the national order. This registry represents the first collaborative effort to provide a knowledge base of this disease, including 5 scientific societies that represent different specialties (pediatrics, rheumatology, pulmonology and cardiology) with data from 23 Argentine provinces. These efforts involved five societies of various adult (cardiology, rheumatology, and pulmonology) and pediatric (cardiology) specialties.

Vitamin D deficiency among patients with pulmonary hypertension.

Background: There is little information about vitamin D (Vit D) deficiency in patients with pulmonary hypertension (PH). The objective of this study was: 1) compare Vit D levels between patients with PH, left ventricular failure (LVF) and healthy subjects (HS); 2) correlate, in patients with PH, Vit D levels with prognosis-related variables, such as the 6-min walk test (6MWT).

Methods: Vitamin D levels were measured in a cross-sectional study in 126 patients from one of three groups: patients with PH (n = 53), patients with LVF (n = 42) and healthy subjects (n = 31).

Medical Students' Attitude Toward Organ Donation: Understanding Reasons for Refusal in Order to Increase Transplantation Rates.

Objectives: To assess, among medical students, the willingness to donate their own organs or those of a family member, and to establish reasons for refusal.

Materials And Methods: During the 2016 academic year, an anonymous survey was conducted among University of Buenos Aires School of Medicine second-year students.

Results: Of the total 1012 respondents, 81.

Physical Activity Among Organ Recipients: Data Collected From the Latin American Transplant Games.

Background: Cardiovascular complications after transplantation are an important cause of non-transplant-related deaths. Depression and anxiety are not unusual among organ recipients. Physical activity reduces cardiovascular risk and promotes a sensation of well-being.

Symptomatic, Inspiration-Induced Atrioventricular Block: Treated with Pacemaker Implant.

Background: The respiratory sinus arrhythmia is the most common cardiac arrhythmia. It consists of phasic variations of sinus cycle length produced by an autonomic reflex, and is characterized by increased heart rate during inspiration and decline in expiration. This phenomenon is due to a reduction of the parasympathetic tone during inspiration, causing a rise in the heart rate, while during expiration the opposite phenomenon occurs.
