Screening for coronavirus disease 2019 in pregnant women admitted for delivery: an observational study.

Objective: The aim of this study was to examine the impact of symptom-based screening on the prevalence and outcomes of neonatal coronavirus disease 2019 in pregnant women admitted for delivery.

Methods: A retrospective observational study was conducted from June to August 2020 at Gonzaga Mota of Messejana Hospital, Fortaleza, CE, Brazil. All pregnant women were screened for coronavirus disease 2019 based on symptoms.

Latex proteins downregulate inflammation and restores blood-coagulation homeostasis in acute Salmonella infection.

Background: Calotropis procera latex protein fraction (LP) was previously shown to protect animals from septic shock. Further investigations showed that LP modulate nitric oxide and cytokines levels.

Objectives: To evaluate whether the protective effects of LP, against lethal bacterial infection, is observed in its subfractions (LPPII and LPPIII).

Poorly differentiated vaginal adenocarcinoma with aggressive behavior-Pap smear findings.

Vaginal carcinoma is a rare condition. In this report, we describe a case of a poorly differentiated aggressive adenocarcinoma in a woman with a three month history of vaginal bleeding and a negative Pap smear done six months prior to her consultation. Specular examination showed a normal cervix, but there was a bleeding ulcer (2 cm in diameter) in the upper third of the vagina.

Liquid-based cytology and HPV DNA testing using intra-anal specimens from HIV-negative women with and without genital HPV-induced lesions.

Background: Screening for anal cancer using cytology has not been considered in immunocompetent women. The aim of this study was to identify cytological atypia and human papillomavirus (HPV) DNA in intra-anal specimens from human immunodeficiency virus (HIV)-negative women with and without genital HPV lesions.

Methods: This study was a cross-sectional analysis of 142 women who were negative for the HIV: 80 with genital lesions that were associated with HPV and 62 without HPV-induced lesions.

Isoniazid-resistant Mycobacterium tuberculosis strains arising from mutations in two different regions of the katG gene.

Objective: To analyze and compare the mutations in two different regions of the katG gene, which is responsible for isoniazid (INH) resistance.

Methods: We analyzed 97 multidrug-resistant Mycobacterium tuberculosis strains isolated in cultures of sputum samples obtained from the Professor Hélio Fraga Referral Center, in Brasília, Brazil. Another 6 INH-sensitive strains did not present mutations and were included as controls.

Clinical evolution of a group of patients with multidrug-resistant TB treated at a referral center in the city of Rio de Janeiro, Brazil.

Objective: To analyze the clinical characteristics and evolution of a group of patients with positive sputum cultures for multidrug-resistant (MDR) Mycobacterium tuberculosis and treated at a referral center in the city of Rio de Janeiro, Brazil.

Methods: Based on the positive results in sputum cultures for MDR M. tuberculosis, 50 patients were selected, and their clinical data were obtained from the Brazilian Ministry of Health MDR-TB Database.

Relationships between bacterial diversity and environmental variables in a tropical marine environment, Rio de Janeiro.

This study is the first to apply a comparative analysis of environmental chemistry, microbiological parameters and bacterioplankton 16S rRNA clone libraries from different areas of a 50 km transect along a trophic gradient in the tropical Guanabara Bay ecosystem. Higher bacterial diversity was found in the coastal area, whereas lower richness was observed in the more polluted inner bay water. The significance of differences between clone libraries was examined with LIBSHUFF statistics.

Archaeal communities in a tropical estuarine ecosystem: Guanabara Bay, Brazil.

Guanabara Bay is an eutrophic estuarine system located in a humid tropical region surrounded by the second largest metropolitan area of Brazil. This study explores the contrasting environmental chemistry and microbiological parameters that influence the archaeaplankton diversity in a pollution gradient in Guanabara Bay ecosystem. The environments sampled ranged from completely anoxic waters in a polluted inner channel to the adjacent, relatively pristine, coastal Atlantic Ocean.

Characterization of an epidemic carbapenem-resistant Pseudomonas aeruginosa producing SPM-1 metallo-beta-lactamase in a hospital located in Rio de Janeiro, Brazil.

Metallo-beta-lactamase production is emerging worldwide as an important mechanism of carbapenem resistance among nonfermentative Gram-negative isolates, and this mechanism is becoming frequently observed in Brazil. This study documents the occurrence and characteristics of an epidemic SPM-1-producing Pseudomonas aeruginosa strain in a teaching hospital located in Rio de Janeiro City, Brazil. The bla (SPM-1) gene and a class 1 integron were detected in 13 isolates, representing 20% of the 65 imipenem-resistant P.
