Agreement between software programmes of body composition analyses on abdominal computed tomography scans of obese adults

ABSTRACT Objective A large number of studies have used abdominal computed tomography (CT) to quantify body composition, and different software programmes have been used to perform these analyses. Thus, this comparison is important to enable researchers to know the performance of more accessible softwar...

Development and validation of a simple and rapid way to generate low volume of plasma to be used in point-of-care HIV virus load technologies

Braz. j. infect. dis; 24 (1), 2020
ABSTRACT A new point-of-care HIV viral load, mPIMA HIV-1/2 VL, Abbott, USA, has been recently developed. This point-of-care viral load requires no skilled person to run and uses a small plasma volume (50 µL). However, obtaining 50 µL of plasma can be a challenge in limited resource settings. We validat...

Diagnostic parameters and reliability of four rapid immunochromatographic tests for dengue 4

Braz. j. infect. dis; 24 (1), 2020
ABSTRACT Background: Although performance of rapid immunochromatographic tests (RITs) for dengue virus (DENV) serotypes 1, 2 and 3 is relatively settled, evidence on accuracy of RITs for DENV-4 are based on studies with small sample sizes and with discrepant results. Objectives: To assess accuracy and ...

The influence of phytoestrogens or estrogens on the proliferation of the rat endocervical mucosa

SUMMARY INTRODUCTION Although estrogen therapy is widely used against post-menopausal symptoms, it can present adverse effects, including endometrial cancer. Soy isoflavones are considered a possible alternative to estrogen therapy. However, there are still concerns whether isoflavones exert trophic ef...

Mechanical thrombectomy for reperfusion of acute ischemic stroke in a Stroke Unit in Argentina

Arq. neuropsiquiatr; 78 (1), 2020
Abstract Stroke is an important cause of morbidity and mortality worldwide. Reperfusion therapy with intravenous tissue plasminogen activator (IV-tPA) was first implemented in 1996. More recently, endovascular reperfusion with mechanical thrombectomy (MT) demonstrated a robust beneficial effect, extendin...
