Impact of a radiological protection campaign in emergency paediatric radiology: a multicentric observational study in Brazil.

Purpose: To evaluate the impact of a paediatric radiological protection campaign, implemented in the emergency units of a healthcare provider network in Brazil. This campaign aimed to promote awareness among emergency department physicians, regarding justification of paediatric X-ray referrals for paranasal sinus, chest and CT exams, as a strategy to reduce exposure to ionising radiation.

Method: Frequency analysis of common paediatric imaging referrals from 19 emergency departments was performed for a 3-year period (2015-2018) to coincide with before, during and after the implementation of the radiation protection campaign.

Maternal and fetal outcome in women with hypertensive disorders of pregnancy: the impact of prenatal care.

Background: Hypertensive disorders of pregnancy (HDP) are the most important cause of maternal and fetal death and pregnancy complications in Latin America and the Caribbean.

Objectives: The objective of this study was to characterize the epidemiological profile of women with HDP admitted to a Brazilian tertiary reference hospital, and to evaluate maternal and fetal outcome in each HDP and the impact of prenatal care on the maternal and fetal outcome.

Methods: HDP in 1501 women were classified according to usual definitions as chronic hypertension (n = 564), pre-eclampsia (n = 579), eclampsia (n = 74) and pre-eclampsia/eclampsia superimposed on chronic hypertension (n = 284).

Family clustering of secondary chronic kidney disease with hypertension or diabetes mellitus. A case-control study.

In Brazil hypertension and type 2 diabetes mellitus are responsible for 60% of cases of end-stage renal disease in renal replacement therapy. In the United States studies have identified family clustering of chronic kidney disease, predominantly in African-Americans. A single Brazilian study observed family clustering among patients with chronic kidney disease when compared with hospitalized patients with normal renal function.

Frequency and clinical predictors of coronary artery disease in chronic renal failure renal transplant candidates.

Background/aims: Cardiovascular diseases are major causes of mortality in chronic renal failure patients before and after renal transplantation. Among them, coronary disease presents a particular risk; however, risk predictors have been used to diagnose coronary heart disease. This study evaluated the frequency and importance of clinical predictors of coronary artery disease in chronic renal failure patients undergoing dialysis who were renal transplant candidates, and assessed a previously developed scoring system.

Parameters of glycemic control in type 2 diabetic patients on hemodialysis or peritoneal dialysis: implications for clinical practice.

Objective: To better explore the relationship between parameters of glycemic control of T2DM in RRT, we studied 23 patients on hemodialysis (HD), 22 on peritoneal dialysis (PD), and compared them with 24 T2DM patients with normal renal function (NRF).

Materials And Methods: We performed, on four consecutive days, 10 assessments of capillary blood glucose [4 fasting, 2 pre- and 4 postprandial (post-G) and average (AG)], random glycemia, and HbA1c in all patients.

Results: Preprandial blood glucose was greater in patients on RRT compared with NRF.

Similarity between blood pressure values assessed by auscultatory method with mercury sphygmomanometer and automated oscillometric digital device.

Introduction: One of the biggest challenges in the management of hypertension is adequate blood pressure (BP) control. To achieve this goal, home blood pressure measurement (HBPM) with automated devices has been encouraged. However, part of the medical community still disputes its validity, believing that HBPM may lead to incorrect readings.

Assessment of social and economic influences on blood pressure of adolescents in public and private schools: an epidemiological study.

Introduction: The high prevalence of hypertension in high school students in Sorocaba, São Paulo, Brazil, has already been described. In this study, within a new sample of high school students from public and private schools, we evaluated if socioeconomic and lifestyle influence on blood pressure values.

Methods: This is an epidemiological study, which is part of the activities of a community-based work conducted by medical students.
