Infectious SARS-CoV-2 Particles from Rectal Swab Samples from COVID-19 Patients in Brazil.

The main objective of this study was to investigate the dynamic of SARS-CoV-2 viral excretion in rectal swab (RS), saliva, and nasopharyngeal swab (NS) samples from symptomatic patients and asymptomatic contacts. In addition, in order to evaluate the replication potential of SARS-CoV-2 in the gastrointestinal (GI) tract and the excretion of infectious SARS-CoV-2 from feces, we investigated the presence of subgenomic nucleoprotein gene (N) mRNA (sgN) in RS samples and cytopathic effects in Vero cell culture. A prospective cohort study was performed to collect samples from symptomatic patients and contacts in Rio de Janeiro, Brazil, from May to October 2020.

SARS-CoV-2 variant N.9 identified in Rio de Janeiro, Brazil.

Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) B.1.1.

Isolation of Infective Zika Virus from Urine and Saliva of Patients in Brazil.

Background: Zika virus (ZIKV) is an emergent threat provoking a worldwide explosive outbreak. Since January 2015, 41 countries reported autochthonous cases. In Brazil, an increase in Guillain-Barré syndrome and microcephaly cases was linked to ZIKV infections.

Reliability of the measures of weight-bearing distribution obtained during quiet stance by digital scales in subjects with and without hemiparesis.

Described as an alternative way of assessing weight-bearing asymmetries, the measures obtained from digital scales have been used as an index to classify weight-bearing distribution. This study aimed to describe the intra-test and the test/retest reliability of measures in subjects with and without hemiparesis during quiet stance. The percentage of body weight borne by one limb was calculated for a sample of subjects with hemiparesis and for a control group that was matched by gender and age.

Reliability of the Functional Reach Test and the influence of anthropometric characteristics on test results in subjects with hemiparesis.

First designed as an alternative method of assessing balance and susceptibility to falls among elderly, the Functional Reach Test (FR) has also been used among patients with hemiparesis. Then this study aimed to describe the intra- and inter-rater and the test/re-test reliability of the FR measure in subjects with and without hemiparesis while verifying anthropometric influences on the measurements. The FR was administered to a sample of subjects with hemiparesis and to a control group that was matched by gender and age.

A transient increase in total head phosphotyrosine levels is observed upon the emergence of Aedes aegypti from the pupal stage.

Phosphorylation and dephosphorylation of protein tyrosine residues constitutes a major biochemical regulatory mechanism for the cell. We report a transient increase in the total tyrosine phosphorylation of the Aedes aegypti head during the first days after emergence from the pupal stage. This correlates with an initial reduction in total head protein tyrosine phosphatase (PTP) activity.

Is it correct to always consider weight-bearing asymmetrically distributed in individuals with hemiparesis?

Injuries may cause unilateral deterioration of brain areas related to postural control resulting in lateralized motor disability with abnormal asymmetry in weight-bearing distribution. Although overloading toward the nonaffected limb has been described as the preferred posture among individuals with hemiparesis, characterization of the weight-bearing asymmetry is poorly and indirectly described. Therefore, this study aimed to describe weight-bearing distribution during upright stance, establishing criteria to consider asymmetry in hemiparesis when analyzed within the limits defined by controls matched by age and gender.

A Brazilian experience to describe functioning and disability profiles provided by combined use of ICD and ICF in chronic stroke patients at home-care.

Purpose: To present experience of combined use of the International Classifications to determine functioning and disability profiles of chronic stroke patients at home-care.

Methods: It was a design observational study with 13 subjects sampled from 39 patients with stroke pre-selected from 115 patients attended by a public home-care service. Their socio-demographic and others independent variables were assessed and frequencies of codified events from International Classification of Diseases (ICD) and International Classification of Functioning, Disability and Health (ICF) were recorded.
