Neighborhoods or residential environments have physical and social attributes which may contribute to inequalities in the overweight and obesity pandemic. We examined the longitudinal associations of baseline neighborhood-level income and racial residential segregation (using the Gi* statistic: low, medium, high) with changes in body mass index (BMI in kg/m), using geocoded data from 1821 civil servants in the municipality of Rio de Janeiro, Brazil, followed-up for approximately 13 years (baseline wave 1: 1999, wave 2: 2001-2002, wave 3: 2006-2007, wave 4: 2012-2013). Linear mixed effects models using BMI measured in all four study waves were performed, accounting for gender, race, length of residence, education and time-dependent age, and per capita family income.

Insufficient quality of the underlying cause of death in the Brazilian Mortality Information System (SIM), acronym in Portuguese underlists violence and it is necessary to redistribute garbage causes (GC) into valid causes in public health prevention. This study estimated mortality from external causes using the GC redistribution method (GBD-Brazil) and compared it with SIM and estimated data from the GBD-IHME study from 2010 to 2019 in Brazil and its states. The GBD-Brazil GC redistribution algorithm applies previous steps of the GBD-IHME with modifications, using two criteria: proportion of target causes (valid) or reclassification of investigated causes.

Background: The High-Dose Erythropoietin for Asphyxia and Encephalopathy (HEAL) trial for neonates with hypoxic-ischemic encephalopathy (HIE) treated with therapeutic hypothermia demonstrated no neurodevelopmental benefit but was associated with a higher rate of serious adverse events (SAEs). Understanding if targeted Epo plasma exposures were achieved in the HEAL trial and if SAEs were associated with higher exposures would help future therapeutic programs of Epo as a candidate neuroprotective treatment.

Methods: Ancillary study of a subset of HEAL neonates who received Epo (1000 U/kg IV on days 1, 2, 3, 4, and 7) and had plasma drug concentrations measured.

Metagenome-assembled genomes (MAGs) have contributed to identifying non-culturable microorganisms and understanding their ecological functions. MAGs offer an advantage in investigating sporulation-associated genes, especially given the difficulty of isolating many species residing in the gut microbiota of multiple hosts. Bacterial sporulation is a key survival mechanism with implications for pathogenicity and biotechnology.

Article Synopsis
  • Stress management is crucial for pathogens to survive and establish infections in harsh environments, specifically addressing thermal, oxidative, and osmotic stresses.
  • The study identifies the roles of key signaling proteins (Ras1, Hog1, calcineurin) in regulating glycerol synthesis, which helps fungi cope with cationic stress; deletion of certain genes disrupts this process and reduces virulence.
  • A novel transcriptional profile in glycerol-deficient mutants was established that highlights the biological processes affected by calcineurin-mediated stress response, offering insights into pathogen adaptability mechanisms.

The exponential growth of metatranscriptomic studies dedicated to arboviral surveillance in mosquitoes has yielded an unprecedented volume of unclassified sequences referred to as the virome dark matter. Mosquito-associated viruses are classified based on their host range into Mosquito-specific viruses (MSV) or Arboviruses. While MSV replication is restricted to mosquito cells, Arboviruses infect both mosquito vectors and vertebrate hosts.

Background: Mangroves are complex and dynamic coastal ecosystems under frequent fluctuations in physicochemical conditions related to the tidal regime. The frequent variation in organic matter concentration, nutrients, and oxygen availability, among other factors, drives the microbial community composition, favoring syntrophic populations harboring a rich and diverse, stress-driven metabolism. Mangroves are known for their carbon sequestration capability, and their complex and integrated metabolic activity is essential to global biogeochemical cycling.

The "Amazon tipping point" is a global change scenario resulting in replacement of upland forests by large-scale "savannization" of mostly southern and eastern Amazon. Reduced rainfall accompanying the Last Glacial Maximum (LGM) has been proposed to have acted as such a tipping point in the past, with the prediction that inhabiting species should have experienced reductions in population size as drier habitats expanded. Here, we use whole-genomes of an Amazonian endemic organism (Scale-backed antbirds - spp.
