Prevalence and Associations of Xerostomia in Older Adults in Southern Brazil.

Objectives: This study investigated the prevalence and associations of xerostomia in older adults in southern Brazil.

Methods: A cross-sectional study was carried out in Pelotas, Brazil, during 2014. A representative sample of the city's older adult population (60+) was selected.

Resilience Informatics in Public Health: Qualitative Analysis of Conference Proceedings.

Background: In recent years, public health has confronted 2 formidable challenges: the devastating COVID-19 pandemic and the enduring threat of climate change. The convergence of these crises underscores the urgent need for resilient solutions. Resilience informatics (RI), an emerging discipline at the intersection of informatics and public health, leverages real-time data integration from health systems, environmental monitoring, and technological tools to develop adaptive responses to multifaceted crises.

Factors associated with menstrual-related disturbances following SARS-CoV-2 vaccination: a Spanish retrospective observational study in formerly menstruating women.

Background: A growing body of evidence suggests a potential link between the SARS-CoV-2 vaccine and menstrual changes in women who were menstruating at the time of vaccination. Nevertheless, the prevalence of this event in those with secondary amenorrhea for different causes, i.e.

Safety Assessment of Graphene-Based Materials.

Graphene is the first 2D atomic crystal, and its isolation heralded a new era in materials science with the emergence of several other atomically thin materials displaying multifunctional properties. The safety assessment of new materials is often something of an afterthought, but in the case of graphene, the initial isolation and characterization of the material was soon followed by the assessment of its potential impact on living systems. The Graphene Flagship project addressed the health and environmental aspects of graphene and other 2D materials, providing an instructive lesson in interdisciplinarity - from materials science to biology.

Dredging and sediment discharge in a river with floodplain. Physicochemical and microbiological effects in Paraná river.

Alterations caused by human activities in the environment, such as dredging, modify the physicochemical conditions and affect the habitat. Maintenance dredging that allows large vessels access to inland ports is a recurring disruptive action. The study aimed to evaluate, during a maintenance dredging operation in a port area of the Paraná River, the modifications in the structure of the river, the presence of contaminants and bacterial organisms.
