Repeated adolescent pregnancy in Brazil from 2015 to 2019.

Objective: The aim of this study was to assess the rate of repeated pregnancy in adolescence and its association with early marriage and education level.

Methods: This is a cross-sectional study conducted by searching the Live Births Data System. The study included all adolescents in the age group 10-19 years with live births from 2015 to 2019 (n=2,405,248), divided into three groups: G1: primiparas; G2: with 1 previous pregnancy; and G3: with two or more previous pregnancies.

Suboptimal control of cardiovascular risk factors in myocardial infarction survivors in a cardiac rehabilitation program.

Introduction And Objectives: As short-term mortality continues to decrease after myocardial infarction (MI), secondary prevention strategies attain increasing relevance. This study aimed at assessing the control of cardiovascular (CV) risk factors, including dyslipidemia, hypertension and diabetes, in a contemporary cohort of MI survivors who completed an exercise-based cardiac rehabilitation (EBCR) program.

Methods: Observational, retrospective cohort study including patients admitted to a tertiary center with acute MI between November 2012 and April 2017, who completed a phase II EBCR program after discharge.

Increase in fertility rate before the age of 14 in Brazil from 1996 to 2018.

Objective: This study aimed to assess live birth frequency and age-specific fertility rates (ASFR) in the period 1996-2018 and the number of pregnancies at <14 years old in the period 2012-2018.

Methods: This was a cross-sectional study conducted by search on Live Births Data System (SINASC/DATASUS) database.

Results: There was a variation in ASFR in Brazil of 0.

Cardiac rehabilitation in elderly myocardial infarction survivors: focus on circulatory power.

Exercise-based cardiac rehabilitation (EBCR) is paramount after an acute myocardial infarction (AMI). Older individuals have been reported as having a worse prognosis after an AMI, and some series have reported differences in the functional response to EBCR. The peak circulatory power (CP), a non-invasive parameter, has been described as a surrogate for the cardiac power, showing promising results as a comprehensive measure of the cardiovascular response.

Differential impact of a cardiac rehabilitation program in functional parameters according to patient gender.

Introduction: Exercise-based cardiac rehabilitation (EBCR) programs are of paramount importance in the management of acute myocardial infarction (AMI) survivors. Albeit this, female patients tend to be less referred for these programs, while also having a poorer prognosis. We aimed at assessing the impact of a contemporary EBCR program on functional parameters after an AMI, and specifically the impact of gender on its potential benefits.

Differential Impact of a Cardiac Rehabilitation Program on Functional Parameters in Elderly versus Non-Elderly Myocardial Infarction Survivors.

Background: Exercise-based cardiac rehabilitation (EBCR) plays a pivotal role in the management of acute myocardial infarction (AMI). Studies have shown that older individuals have a worse prognosis after an AMI, attesting to the importance of risk reduction strategies. We aimed at assessing the impact of age (patients dichotomized as ≥65 years old or <65 years old) on the functional benefits of an EBCR program among AMI survivors.

Adolescent pregnancy trends in the last decade.

Introduction: Teenage pregnancy is a universal phenomenon, with higher prevalence in developing countries. Although there has been a reduction in Brasil since the year 2000, the age-specific fertility rate for this age group remains high.

Objective: To evaluate the frequency of adolescence pregnancy in in Brasil from 2006 to 2015 and its association with the Human Development Index (HDI).

Postnatal and postabortion care during adolescence in the National Health System in Rio de Janeiro, Brazil.

Objective: To study postnatal and postabortion outpatient care for adolescents in relation to the guidelines of the Brazilian Ministry of Health.

Methods: The present cross-sectional study was conducted between 2011 and 2012 via interviews with coordinators from 147 of 148 (99.3%) National Health System facilities providing sexual and reproductive healthcare for adolescents in the city of Rio de Janeiro, Brazil.

Heart rate variability in myocardial infarction patients: effects of exercise training.

Heart rate variability (HRV) is a simple and noninvasive measure that estimates cardiac autonomic modulation, mainly the parasympathetic contribution. Increased sympathetic and/or decreased parasympathetic nervous activity is seen in post-myocardial infarction (MI) patients. Consequently, these patients present reduced HRV, which has been associated with increased risk of adverse events and mortality.

[Breast cancer during pregnancy and chemotherapy: a systematic review].

This study aimed to establish the safety of chemotherapy use in pregnant women with breast cancer, and to find possible effects in the fetus. A search of MEDLINE/PubMed, LILACS, SciELO, Cochrane, UpToDate, and Google Scholar databases was performed to identify publications, 86 articles published from 2001 to 2012 were retrieved and evaluated by two readers in accordance predetermined exclusion and inclusion criteria; 39 articles were selected. All the chemotherapy drugs used to treat breast cancer during pregnancy belonged to class D, and consisted of 5-fluorouracil (F), doxorubicin (A) or epirubicin (E) and cyclophosphamide (C), or the combination doxorubicin and cyclophosphamide (AC), a safe regimen when used after the first trimester of pregnancy.

Exercise training enhances autonomic function after acute myocardial infarction: a randomized controlled study.

Introduction: Heart rate recovery, defined as the fall in heart rate during the first minute after exercise, is an indicator of autonomic function, and has been found to be an independent predictor of mortality after acute myocardial infarction. Exercise training has several well-known benefits in terms of cardiorespiratory fitness, modifiable cardiovascular risk factors and prognosis after acute coronary events. However, there are no randomized controlled studies in the literature evaluating the effects of exercise training per se, controlling for changes in medication and diet, on heart rate recovery.

Ototoxicity study in workers exposed to organophosphate.

Unlabelled: Occupational and environmental exposure to agricultural pesticides represent an important health care problem in our country. Among the symptoms presented, dizziness stands out, because of a probable toxic action.

Aim: The goal of our study was to characterize vestibular test results from rural workers occupationally and environmentally exposed to organophosphates used in agricultural pesticides.

Impact of cardiac rehabilitation on quality of life and depression after acute coronary syndrome.

Objective: To evaluate the impact of cardiac rehabilitation programs (CRP) on quality of life (QL) and depression at one-year follow-up after acute coronary syndrome (ACS).

Methods: Two hundred and three patients, without previous cardiological follow-up and referred to the outpatient clinic after hospitalization for ACS between 9/1/2001 and 12/31/2002, were randomly allocated to a 12-week, 3-times-a-week CRP or standard cardiology follow-up only, after giving their informed consent. Baseline population characteristics were recorded and, in patients with more than 4 years' education, QL and depression were evaluated during hospitalization and at one-year follow-up by self-reported responses to the SF-36 QL survey and the Beck Depression Inventory (BDI) respectively.
