Aquatic and palustrine plants are a group of plants that have morphological and anatomical adaptations to occupy permanent or temporary aquatic environments. In this study, we carried out the first floristic survey of aquatic and palustrine plants in restingas (restinga swamps and swamp forests) of a Ramsar site in the municipality of Guimarães, western coast of Maranhão State and easternmost Amazon, Brazil. In total, 52 species of 43 genera and 28 families were collected between July 2022 and October 2023, during the dry and rainy seasons.

Methods: Patients were included consecutively between March 2013 and April 2016.
Heart failure associated with chronic Chagas cardiomyopathy increases the risk of impaired lung function and reduced submaximal functional capacity.

Article Synopsis
- - The study investigates the differences in respiratory function and physical capacity between patients with chronic Chagas cardiomyopathy (CC) who have heart failure (HF) and those who do not.
- - Using spirometry and a six-minute step test, the results showed that patients with HF had significantly lower lung function and functional capacity compared to those without HF.
- - Conclusively, the research indicates that adults with CC and HF exhibit reduced lung function, suggesting a restrictive pulmonary pattern impacting their overall health.
Article Synopsis
- A study was conducted to assess the safety and efficacy of COVID-19 vaccinations in liver cirrhosis patients, three years into the pandemic, due to ongoing uncertainties in this demographic.
- The research included 124 liver cirrhosis patients, focusing on their antibody responses post-vaccination over different time intervals, as well as any adverse effects experienced.
- Results indicated that while 18% experienced mild adverse events, a significant portion had inadequate antibody responses over time, with factors like older age and type of vaccine linked to poorer outcomes.
Background: A better understanding of the consequences of the Coronavirus Disease 2019 (COVID-19) pandemic on lifestyle of patients with Chagas disease (ChD) is of paramount importance to facilitate the implementation of intervention strategies tailored to this specific population.
Objective: The present study aimed to evaluate the level of physical activity (PA) in Chagas disease (ChD) patients during the Coronavirus Disease 2019 (COVID-19) pandemic and its main associated factors.
Methods: This is a cross-sectional study with 187 patients of both sexes, aged ≥18 years, followed in a national infectious disease center (Rio de Janeiro, Brazil).
