The COVID-19 epidemic in Brazil: how statistics education may contribute to unravel the reality behind the charts.

The world is now facing the most severe health, social, and economic event of the last hundred years, which has made the need to acquire statistical thinking to interpret the information disseminated on a daily basis by the media clear to society. This article proposes a discussion on the role that statistics education might play in supporting the acquisition of such knowledge, contributing to the development of critical citizens, aware of their social responsibility. In this context, we present examples of curves and other charts to demonstrate how to use the several levels defined by experts in reading and interpreting the charts.

The influence of nursing activities score on clinical alarms service.

Objectives: to estimate the magnitude of the Nursing Activities Score effect on multiparametric monitor alarm response and staff response time.

Methods: an observational, cross-sectional study outlined as an open cohort, performed in an Adult General Intensive Care Unit. The time taken for alarms triggered by the multi-parameter monitors was timed and characterized as attended or not.

Handling errors in conventional and smart pump infusions: A systematic review with meta-analysis.

Objective: To identify the scientific evidence on the frequency of handling errors of conventional and smart pump infusions in intravenous insulin therapy in intensive care units.

Method: A systematic review with meta-analysis conducted in the Virtual Health Library, MEDLINE via PubMed, Scopus and Web of Science databases. Articles were assessed regarding the level of evidence by applying the Oxford Center for Evidence-Based Medicine Evidence Scale.

The representation of getting ill in adolescents with systemic lupus erythematosus.

Introduction: This study, developed in a federal hospital in the city of Rio de Janeiro, has aimed to analyze the social representation of chronic disease and its treatment, in the perspective of adolescents and their caregivers.

Methods: The sample consisted of 31 adolescents (11-21 years) with systemic lupus erythematosus and 19 caregivers (32-66 years), followed in the pediatrics and in the internal medicine outpatient clinics for a period of six months. Data was collected from the free association of words test, using chronic disease and treatment of chronic disease impulses, and later submitted to the Multiple Correspondence Analysis using the R software.

Design: Prospective cohort study with an 18-month follow-up.

Setting: A 16-bed medical and/or surgical pediatric intensive care unit that cares for patients of the Brazilian Public Health System exclusively.

Risk factors for healthcare-associated infection in a pediatric intensive care unit.

Design: Prospective cohort study.

Setting: Medical-surgical PICU in a hospital for patients in the public healthcare system.

[Stroke prevalence among the elderly in Vassouras, Rio de Janeiro State, Brazil, according to data from the Family Health Program].

This study estimated the prevalence of stroke among the elderly in Vassouras, Rio de Janeiro State, Brazil, based on data from the Family Health Program (FHP). The elderly population was chosen since it is growing as a proportion of the general population, and since stroke risk increases with age. Data were screened for all the elderly registered in the FHP in Vassouras, identifying those with a history of stroke and analyzing their socio-demographic profile.

[A methodology to estimate incidence from prevalence rates in household surveys: the example of literacy].

Age and time-specific incidence rates are highly relevant to epidemiologists. Due to the mathematical relationship between incidence and prevalence, several methods have been developed to obtain incidence based on prevalence. The present study didactically describes a method to estimate age and time incidence, based on: repeated measurements of prevalence for an event; events related to the individual's age; and events with the characteristics of a chronic disease.

Effect of predominant breastfeeding duration on infant growth: a prospective study using nonlinear mixed effect models.

Objective: The aim of this study is to assess the effect of predominant breastfeeding duration on infant growth by means of repeated measurements model.

Methods: This prospective study is comprised of four follow-up evaluations at approximately 0.5, 2, 6 and 9 months after birth, including structured interviews that simultaneously gathered information regarding infant growth and breastfeeding practices.

[Breastfeeding practices and infant growth: a longitudinal study in Rio de Janeiro, Brazil, 1999/2001].

Various studies have shown significant differences in growth patterns between breastfed and formula-fed infants. This paper aims to evaluate the effect of predominant breastfeeding duration on anthropometric profile and to detect determinants associated with growth in Brazilian infants. Four hundred and seventy nine infants were studied in a health center in Rio de Janeiro through a longitudinal study with four follow-up waves at 0.
