Predicting COVID-19 cases in Belo Horizonte-Brazil taking into account mobility and vaccination issues.

The pandemic caused millions of deaths around the world and forced governments to take drastic measures to reduce the spread of Coronavirus. Understanding the impact of social distancing measures on urban mobility and the number of COVID-19 cases allows governments to change public policies according to the evolution of the pandemic and plan ahead. Given the increasing rates of vaccination worldwide, immunization data may also represent an important predictor of COVID-19 cases.

Background: Determinants of oral language comprehension, a complex skill, are not clearly established, but may include age, schooling, health condition, depression and quality of life.

Objective: To assess oral comprehension skill among Brazilian elderly and identify factors explaining elderly variability in the Token test performance.

Methods: A population-based random sample of 373 elderly (> or = 60 years) in Belo Horizonte, 2007, answered standardized questionnaire including socio-demographic and health-related questions and performed the Token Test short version (SVTT), Snellen Test, Mini Mental State Examination, General Health Questionnaire, and Health Survey Short Form (SF12).

Mortality and hospital stay after bariatric surgery in 2,167 patients: influence of the surgeon expertise.

Background: Postoperative mortality is a rare event after bariatric surgery. The main goal of this study was to calculate the 30-day mortality rate postbariatric "open" surgery and the length of hospital stay of patients assisted by a health maintenance organization in Brazil. We also investigate their association with sex, age, BMI, preexisting comorbidities, and volume of procedures performed by surgeons.

Hospital admission and hospital death associated to ischemic heart diseases at the National Health System (SUS).

Background: Analyses on mortality rate due to diseases when outcome depends on proper, timely medical intervention may point out the vulnerabilities and inequity associated to health care access. Ischemic heart diseases will act as models for such assessment.

Objective: The present study investigates factors associated to the hospital death rate of patients admitted to hospital due to acute myocardial infarction (AMI) and heart failure (HF), and whether admittance through Belo Horizonte Municipal Health Office (SMSA-BH) Admission Center (AC) was in any way associated to hospital death after adjustment of relevant factors.

[The hospital bed referral center under the Unified National Health System in Belo Horizonte, Minas Gerais State, Brazil: the case of hospitalization for ischemic heart disease].

The hospital admissions center in Belo Horizonte, Minas Gerais State, Brazil, aims to assure fast, timely, and equitable access to hospitalization services through the Unified National Health System. However, many patients are admitted directly to the hospitals, without going through the admissions center. This study compared the characteristics of hospitalizations in Belo Horizonte in 2002 according to type of access.

Parkinsonism and Parkinson's disease in the elderly: a community-based survey in Brazil (the Bambuí study).

Prevalence of insomnia and associated socio-demographic factors in a Brazilian community: the Bambuí study.

Background: Population-based studies of insomnia among adults residing in communities in developing countries are rare. The objectives of this population-based study were to determine the prevalence and factors associated with insomnia among adults (18 years and over) living in a Brazilian town with 15,000 inhabitants (Bambuí MG) and to determine how the use of different definitions of insomnia affect its prevalence.

Methods: A total of 87.

Prevalence of sleep complaints and associated factors in community-dwelling older people in Brazil: the Bambuí Health and Ageing Study (BHAS).

Background: Population-based studies of insomnia among older people residing in communities in developing countries are rare. The objectives of this population-based study were to determine the prevalence and factors associated with insomnia among older adults (60 years and over) living in a Brazilian town with 15,000 inhabitants (Bambuí MG).

Methods: All 1742 residents in this age group were selected for a structured interview and blood tests.

Biomedical factors associated with hospitalization of older adults: The Bambuí Health and Aging Study (BHAS).

The objective of this study was to identify biomedical factors (body mass index, blood pressure, blood glucose, total cholesterol and fractions, triglycerides, and albumin) associated with hospitalization of older adults. All residents of the town of Bambuí, Minas Gerais State, ages > or = 60 years (n = 1,742) were selected for the study, of whom 1,494 (85.2%) participated.

[Effects of detergents and disinfectants on the development of Ascaris lumbricoides eggs].

Ascaris lumbricoides infection is acquired via ingestion of embryonated eggs of the parasite, thus justifying the search for ovicidal compounds. We studied the effect of 16 household and laboratory detergents and disinfectants on the embryogenesis of this helminth. Children carrying this infection were treated with levamisole.

[Prevalence of intestinal helminths in three regions of Minas Gerais State].

A parasitological assay of feces, through the Kato-Katz method, was undertaken in 18,973 schoolchildren (7 to 14 years old), at primary school level, from a public school of the State of Minas Gerais. Three mesoregions were studied: Tri ngulo Mineiro/ Alto Para ba ( 60 municipalities); northwest Minas Gerais (13) and south/south-west regions of Minas Gerais (144). Among the examined children, 15,545 (82%) were negative; 2,863 (15%) were infected with a single species of helminthes and 565 (3%) were infected by more than one species.

High levels of IgG4 to Schistosoma mansoni egg antigens in individuals with periportal fibrosis.

Specific IgG4 and IgE responses to adult worm antigen and soluble egg antigen (SEA) were examined in 267 individuals from an area in which schistosomiasis mansoni is endemic. Based on information obtained from clinical and sonographic examinations of this sample, the individuals were divided in three groups: 1) 204 individuals without periportal fibrosis, and liver and spleen enlargements; 2) 41 individuals without periportal fibrosis, but presenting with organopathy, with or without organomegaly; and 3) 22 individuals with periportal fibrosis, regardless of their status as having hepatomegaly and/or splenomegaly. Levels of IgG4 to SEA were significantly higher in sera from patients with fibrosis compared with the patients from the other two groups.
