Long-term surveillance of SARS-CoV-2 in the school community from Campo Grande, Brazil.

Background: The COVID-19 pandemic has significantly impacted education systems worldwide, with Brazil being one of the countries with the longest school closures. Over a million children and teenagers have been affected, leading to increased hunger and nutritional deficiencies. This study aimed to implement long-term surveillance of SARS-CoV-2 infections in public and private schools in Campo Grande, Brazil, after returning to in-person classes.

Seroprevalence of antibodies against SARS-CoV-2 in the school community in Campo Grande, state of Mato Grosso do Sul, Brazil, October 2021-November 2022.

Introduction: With the reopening of schools during the coronavirus disease 2019 (COVID-19) pandemic, it was imperative to understand the role of students and education professionals in the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In this paper, we determined the seroprevalence of the SARS-CoV-2 anti-nucleocapsid antibodies in the school community in Campo Grande, the capital and most populous city of the state of Mato Grosso do Sul (Brazil) and evaluated its association with sex, school level, and school type.

Materials And Methods: The survey was carried out in 20 public and private schools in the urban region of Campo Grande using the TR DPP COVID-19 immunoglobulin M/immunoglobulin G (IgM/IgG) kit from the Immunobiological Technology Institute (Bio-Manguinhos, Rio de Janeiro, Brazil).

Incidence and risk factors for medical adhesive-related skin injury in catheters of critically ill patients: A prospective cohort study.

Background: The skin in contact with the adhesives used to secure catheters is vulnerable to medical adhesive-related skin injury (MARSI). The incidence of these injuries and the risks associated with their development have not been accurately estimated previously in critically ill patients.

Aim: The aim of this study was to investigate the incidence and risk factors for MARSI in catheters of critically ill patients.

Paracoccidioidal infection in HIV patients at an endemic area of paracoccidioidomycosis in Brazil.

The association between paracoccidioidomycosis (PCM) and AIDS is relatively rare in contrast to the higher incidence of other systemic mycosis. The explanation may be that AIDS is still predominantly an urban disease, and the PCM is endemic in Latin American rural areas. The aim of this study was to detect the prevalence of Paracoccidioides brasiliensis infection in HIV-positive patients at an endemic area of paracoccidioidomycosis in Brazil.
