Multicenter comparative analysis of local and aggregated data training strategies in COVID-19 outcome prediction with Machine learning.

Machine learning (ML) is a promising tool in assisting clinical decision-making for improving diagnosis and prognosis, especially in developing regions. It is often used with large samples, aggregating data from different regions and hospitals. However, it is unclear how this affects predictions in local centers.

Cognitive Performance in Asymptomatic Elderly People with Hepatitis C: The Role of Education.

Background: Neurotropism of the hepatitis C virus (HCV) can be the source of subtle neuropsychological symptoms in non-cirrhotic patients. Age is a risk factor for cognitive impairment (CI). Thus, asymptomatic elderly people who carry HCV might be at a greater risk of CI.

Prediction models for carbapenem-resistant Enterobacterales carriage at liver transplantation: A multicenter retrospective study.

Background: Carbapenem-resistant Enterobacterales (CRE) colonisation at liver transplantation (LT) increases the risk of CRE infection after LT, which impacts on recipients' survival. Colonization status usually becomes evident only near LT. Thus, predictive models can be useful to guide antibiotic prophylaxis in endemic centres.

Spirituality as a protective factor for chronic and acute anxiety in Brazilian healthcare workers during the COVID-19 outbreak.

Background: Anxiety symptoms (AS) are exacerbated in healthcare workers (HCWs) during the COVID-19 pandemic. Spirituality is known to protect against AS in the general population and it is a construct that differs from religion. It can be assessed using structured questionnaires.

Consuming a low-calorie amount of routine food and drink does not affect bioimpedance body fat percentage in healthy individuals.

Objectives: Bioimpedance analysis is a simple, safe, and relatively inexpensive method to assess body composition. The bioimpedance guidelines recommend that the test be performed after fasting and avoiding the consumption of liquids. Studies have verified the effects of consuming liquids and food on bioimpedance; however, these studies used preestablished meals and hydration.

Assessing the impact of a doctor in remote areas of Brazil.

Objectives: The More Doctors Program (MDP) is an ongoing Brazilian policy that aims to improve healthcare by providing physicians to the most vulnerable municipalities. We aimed to measure the impact of MDP in mortality and infant mortality rate, the proportion of live births with low weight, prenatal appointments, childbirths at first and fifth min Apgar, public health investment and immunization in Brazil.

Methods: Municipal health indicators were collected before and after the intervention (2012 and 2015).

Isolation of Extracellular Vesicles from Leishmania spp.

Exosomes, a class of extracellular vesicles, are released by eukaryotes, bacteria, and archaea, as evident from both in vitro and in vivo studies. These nano-sized double-membraned vesicles play an important role in cell-to-cell communication, dysregulation of the immune system, and pathogenesis in a number of diseases, including leishmaniasis. Leishmania is a genus of obligate intracellular parasites, which infect host macrophages, are transmitted through the bite of a sandfly, and are shown to secrete exosomes with immunomodulatory activities.

Can skinfold thickness equations be substituted for bioimpedance analysis in children?

Objective: The aim of the present study was to evaluate the agreement between the most used skinfold thickness equations with multi-frequency bioimpedance analysis in the prediction of body fat levels in children.

Method: A cross-sectional study of healthy Brazilian community-dwelling individuals. The anthropometric assessment included height, body mass, arm circumference, and waist circumference.

Association between phase angle from bioelectrical impedance analysis and level of physical activity: Systematic review and meta-analysis.

Objective: To evaluate the relationship between physical activity and phase angle.

Design: Systematic Review and Meta-analysis.

Data Sources: Electronic searches of MEDLINE (via PUBMED), EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), SciELO, LILACS, SPORTDiscus, Scopus, and Web of Science from inception to December 10th, 2017.

Factors associated with age at natural menopause among elderly women in São Paulo, Brazil.

Objectives: To analyze factors associated with age at natural menopause in elderly women who are part of the Health, Well-Being and Aging Study- which is a representative sample of elderly residents of the municipality of São Paulo, Brazil.

Methods: Multivariate Cox proportional-hazards analysis using data from a total of 1,415 women with natural menopause. We included 163 women with hysterectomy, oophorectomy, and estrogen therapy as censored data.

Pressure ulcer as a reservoir of multiresistant Gram-negative bacilli: risk factors for colonization and development of bacteremia.

The purpose of this study was to identify the risk factors that predispose patients who are hospitalized with pressure ulcers (PUs) colonized by Gram-negative bacilli (GNB) to develop bacteremia. In addition, we also detected main phenotypes of resistance in infected and uninfected PUs. A prospective cohort study was conducted at the Clinical Hospital of the Federal University of Uberlândia including patients with Stage II or greater PUs, colonized or not with GNB, from August 2009 to July 2010.

Correlation of accessory pathway location with gender and their manifest or concealed presentation.

Background: Atrioventricular reentrant tachycardias account for approximately one third of cases referred for electrophysiological study (EPS). The anatomical substrate responsible for the reentry is an accessory pathway (AP) able to conduct the electrical stimulus in an anterograde, retrograde or bidirectional manner.

Objective: To evaluate the correlation of AP location with the male and female genders and AP clinical presentation, whether manifest or concealed.

[Frequency of colonization and isolated bacteria from the tip of the epidural catheter implanted for postoperative analgesia].

Background And Objective: The increased use of epidural analgesia with catheter leads to the need to demonstrate the safety of this method and know the incidence of catheter colonization, inserted postoperatively for epidural analgesia, and the bacteria responsible for this colonization.

Methods: From November 2011 to April 2012, patients electively operated and maintained under epidural catheter for postoperative analgesia were evaluated. The catheter tip was collected for semiquantitative and qualitative microbiological analysis.

Pressure ulcers colonized by MRSA as a reservoir and risk for MRSA bacteremia in patients at a brazilian university hospital.

Unlabelled: Pressure ulcers (PU) are a major reservoir of methicillin-resistant Staphylococcus aureus (MRSA) in hospitals. The objectives of this study were to estimate the prevalence of MRSA colonization in PU of hospitalized patients with Stage II or higher PU, to identify risk factors for colonization of these wounds, and to ascertain whether MRSA colonization of PU increases the risk of MRSA bacteremia.

Methods: This study was conducted at the Clinical Hospital of Federal University of Uberlandia, MG, Brazil.

Molecular identification of Coccidioides spp. in soil samples from Brazil.

Background: Since 1991 several outbreaks of acute coccidioidomycosis (CM) were diagnosed in the semi-arid Northeast of Brazil, mainly related to disturbance of armadillo burrows caused by hunters while digging them for the capture of these animals. This activity causes dust contaminated with arthroconidia of Coccidioides posadasii, which, once inhaled, cause the mycosis. We report on the identification of C.
