Escalating Health Crisis: Dissecting Mortality Causes and Trends Among Indigenous Populations in Northeast Brazil.

Objectives: In Northeast Brazil, the poorest region of the country, indigenous communities face critical health care challenges. Despite legal entitlements to the Unified Health System (SUS), systemic barriers persist, exacerbating health disparities and mortality. This ecological study analyzed mortality trends and causes of death within the Special Indigenous Sanitary District (DSEI) Alagoas-Sergipe over a decade.

Biochemical analysis of vitreous humor and synovial fluid in the estimation of early postmortem interval: A meta-analytical approach.

The estimation of the postmortem interval (PMI) is a significant challenge in legal medicine and forensic sciences due to the dynamic and continuous decomposition of organisms after death. Thanatochemistry has emerged as a promising area to estimate PMI by measuring the concentrations of postmortem biochemical markers. This systematic review and meta-analysis aimed to summarize evidence on postmortem biochemical alterations in vitreous humor (VH) and synovial fluid (SF) to estimate early PMI.

Accuracy of geometric morphometrics for age estimation using frontal face photographs of children and adolescents: A promising method for forensic practice.

Age estimation is crucial in legal and humanitarian contexts. Forensic professionals may use various procedures to estimate age, including dental analysis, bone density tests, evaluation of physical characteristics including facial bone structure and development, and image-based methods. Although images are often the only material available, visual observation of photographic material is an imprecise method in age estimation, which can compromise judicial decision-making.

Demographic evolution and natural increase projection of the Yanomami indigenous population in Brazil.

The Yanomami population, residing in Brazil's largest indigenous reserve in the Amazon Rainforest, face significant health challenges exacerbated by external threats such as infectious diseases, malnutrition, and mercury contamination from illegal mining. These issues, coupled with inadequate healthcare provision, have led to an alarming increase in mortality rates and potentially threaten the long-term survival of the Yanomami community. This ecological study utilized demographic data from the Special Secretariat of Indigenous Health to explore the demographic evolution and natural increase of the Yanomami Indigenous population in Brazil from 2003 to 2022.
