Antimicrobial susceptibility of gram-negative bacteria: analysis from patients in a laboratory network in Brazil.

Objectives: This study aimed to describe the epidemiology and antimicrobial susceptibility patterns of gram-negative pathogens in Brazil from 2018 to 2020, addressing the gap in national data on healthcare-associated infections, using information from a private laboratory network.

Methods: A cross-sectional study was conducted using a database from Fleury hospital network, a private laboratory in Brazil. The analysis included blood, urine, and lower respiratory tract samples collected from January 2018 to June 2020.

Radiographic findings in dogs from an endemic area for heartworm disease in the state of Rio de Janeiro.

Canine heartworm disease causes significant pulmonary abnormalities, even in asymptomatic cases. This study aimed to compare the chest radiographs of cases infected with with those of heartworm-negative dogs. Fifteen animals treated at a private veterinary clinic in the municipality of Maricá, Rio de Janeiro, underwent chest radiography, regardless of their serological status, for the presence of antigen, and none of them used preventive measures.

Can microplastic pollution be affected by beach nourishment? Assessment in intertidal sediment and bivalves.

Several methods can be used to mitigate coastal erosion, and one of the leading solutions is known as beach nourishment (BN), which involves using dredged material for nourishment, adding sand to extend an eroding beach. Although it has many advantages, the environmental impacts of BN remain poorly understood, especially on plastic pollution, which had not been investigated until this study. We aimed to compare the abundance and distribution of microplastics (MPs) found in intertidal sediments and specimens of the bivalve mollusks Crassostrea brasiliana, Mytella strigata, Perna perna, and Tivela mactroides, collected in two beaches of Vitoria, Southeast of Brazil (da Costa et al.

Activity of ceftolozane/tazobactam and comparators against gram-negative bacilli: Results from the Study for Monitoring Antimicrobial Resistance Trends (SMART - Brazil), 2018‒2021.

Increased spread of antimicrobial resistance by Gram-Negative Bacilli (GNB) poses a global challenge, with exacerbated burden post-pandemic. The aim of this study was to investigate the in vitro activity of ceftolozane/tazobactam and its comparators against the frequently identified GNB isolated from patients admitted to Brazilian medical sites between the year 2018‒2019 and 2020‒2021. The impact of pandemic on antimicrobial resistance and presence of β-lactamase genes were also evaluated.

Plants with Hair Growth Activity for Alopecia: A Scoping Review on Methodological Aspects.

Alopecia is a common dermatological disorder of patchy hair loss with substantial patient burden. Phytotherapeutic compounds are increasingly used as a source of new therapeutic options. This review aimed to synthesize the evidence on plant species in hair growth and the methodological aspects of experimental models.
