Objective: To determine measles and rubella IgG seropositivity in the post-elimination era, based on data generated by the Costa Rican National Reference Center for Virology laboratory at Inciensa from 2012 to 2023.
Methods: Cross-sectional, descriptive, observational study analyzing the frequency of measles IgG and rubella IgG reactivity by enzyme-linked immunofluorescence (ELISA) in 877 subjects.
Results: The average age of the studied individuals was 36 years; 51.
Background: The pandemic caused by SARS-CoV-2 has not only affected humans but also raised concerns about its transmission to wild animals, potentially creating natural reservoirs. Understanding these dynamics is critical for preventing future pandemics and developing control strategies. This study aims to investigate the presence of SARS-CoV-2 in wild mammals at the Belo Horizonte Zoo in Brazil, analyzing the virus's evolution and zoonotic potential.

This study aimed to assess the effect of different carbohydrates on S. mutans viability and bacterial proteome at 2 time points, early attachment (8 h) and biofilm maturation (24 h).

- Lymphangioleiomyomatosis (LAM) is a rare lung disease affecting women, leading to decreased health-related quality of life (HRQoL), with limited understanding of the factors influencing this impairment.
- A study assessed 45 women with LAM, finding the lowest HRQoL scores in general health and vitality, while anxiety (35%) and depression (17%) were prevalent among the participants.
- Results indicated that depression symptoms and exercise capacity significantly impacted HRQoL, while lung function showed weak or no correlation with quality of life.
Article Synopsis
- - Brazil experienced significant COVID-19 impact, highlighted by high death tolls and four main peaks of cases, with the last two waves driven by the emergence of the Omicron variant and its sublineages BA.1, BA.2, BA.4, and BA.5.
- - A study analyzed virus samples from 15 health units in Minas Gerais, revealing that BA.1 and BA.2 were most common in the third wave, while BA.4 and BA.5 dominated the fourth.
- - Findings indicate that vaccination, especially booster doses, played a crucial role in reducing deaths, and the study confirmed the introduction of Omicron subvariants through multiple international cases with continued local transmission.
