Balancing Human Mobility and Health Care Coverage in Sentinel Surveillance of Brazilian Indigenous Areas: Mathematical Optimization Approach

Balancing Human Mobility and Health Care Coverage in Sentinel Surveillance of Brazilian Indigenous Areas: Mathematical Optimization Approach

Motivated by this, we integrated human mobility data with Indigenous population coverage to refine sentinel site selection in Brazil. The boundaries between wild landscapes and human settlements have been increasingly blurred by climate change, agricultural and urban expansion, deforestation, and landscape fragmentation. These compounding factors heighten Indigenous communities’ vulnerability to infectious disease spillover, which can rapidly spread to urban areas [17].

Impact of Primary Health Care Data Quality on Infectious Disease Surveillance in Brazil: Case Study

Brazil is an upper middle-income country with approximately 212.6 million people living in 5570 municipalities [13], and we included all ILI-related PHC encounters occurring during the study period in our analysis. We analyzed data from the Brazilian Unified Health System (SUS), which stands as one of the largest public health systems globally, providing comprehensive and universal health care to the entire population.

Screening for Depression and Anxiety Using a Nonverbal Working Memory Task in a Sample of Older Brazilians: Observational Study of Preliminary Artificial Intelligence Model Transferability

Screening for Depression and Anxiety Using a Nonverbal Working Memory Task in a Sample of Older Brazilians: Observational Study of Preliminary Artificial Intelligence Model Transferability

A recent analysis in Brazil uncovered a depression underdiagnosis prevalence of 63.6% [35]. One of the groups in which they found a high discrepancy is among older participants: people older than 59 years are less likely to receive a depression diagnosis in comparison with all other age categories even after controlling for confounders. They also report higher prevalence for underdiagnoses in participants reporting only 1 medical appointment in the last 12 months.

Analysis of Self-Care Activities in Type 2 Diabetes in Brazil: Protocol for a Scoping Review

Analysis of Self-Care Activities in Type 2 Diabetes in Brazil: Protocol for a Scoping Review

Brazil ranks sixth in the number of cases, with 15.7 million people diagnosed in the 20-79 years age group, which is projected to increase to 23.2 million cases in 2045 [1]. DM can be classified into 4 main types, based on its etiology: type 1 diabetes (T1 D), type 2 diabetes (T2 D), gestational DM, and other types of diabetes. T2 D is the most prevalent form, accounting for approximately 90% to 95% of diabetes cases worldwide [2].

Animated Videos Based on Food Processing for Guidance of Brazilian Adults: Validation Study

In Brazil, according to data from the Surveillance of Risk and Protective Factors for Chronic Diseases by Telephone Inquiry in 2019 [2], UPF already contributed almost one-fifth of the calories consumed, especially from salty cookies and packaged snacks, industrialized bread, sweet cookies, and cold cuts and sausages. A survey carried out by Monteiro and collaborators [3] pointed out that, in middle-income countries, the average growth in sales of these products reached approximately 10%.
