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. Analyzing 4000 photographs from the Brazilian Federal Police database, representing four age groups (6, 10, 14, and 18 years), the study employed automated analysis by marking 28 photogrammetric points. Data were used to establish facial patterns by age and sex using the facial geometric morphometrics method. Performance was assessed through a Multinomial Logistic Regression model, evaluating accuracy, sensitivity, and specificity across the categorical age groups. Analyses were conducted using R software, with a 5 % significance level. The study found that facial geometric morphometrics achieved an overall accuracy of 69.3 % in age discrimination, with higher accuracy in males (74.7 %) compared to females (65.8 %) (p < 0.001). The method excelled at predicting the age of 6-year-olds with 87.3 % sensitivity and 95.6 % specificity but had lower performance at 14 years. It showed greater accuracy in distinguishing age groups with larger age gaps, achieving up to 99.5 % accuracy between certain groups, and was particularly effective in differentiating ages of 6 and 10 years in females and 10, 14, and 18 years in males. The facial geometric morphometrics emerges as a promising approach for age estimation among children and adolescents in forensic settings.

Surveillance of TB-HIV coinfection in Brazil: a space-time approach.

OBJECTIVE: To identify the epidemiological, spatial, and temporal pattern of TB-HIV coinfection in Brazil during the period from 2001 to 2020. METHODS: Ecological study using space-time analysis techniques. It included cases of TB-HIV coinfection registered in Brazil from 2001 to 2020. The temporal trend analysis was performed using segmented regression by Joinpoint regression. For spatial analysis, Moran indices were calculated and choropleth maps were produced using TerraView and QGIS software. RESULTS: A stable temporal trend was observed in the incidence rates of TB-HIV coinfection in Brazil during the analyzed period. In addition, high-risk areas for coinfection located in states in the North, Southeast, South, and Midwest regions were identified. CONCLUSION: There was stability in the incidence of TB-HIV coinfection in Brazil over the last 20 years and heterogeneous geographic distribution of risk areas for the condition.

Space-time analysis of work-related musculoskeletal disorders in Brazil: an ecological study.

This study aimed to analyze the incidence of work-related musculoskeletal disorders (WMSD) in Brazil from 2007 to 2019, examining the spatial, temporal, and spatiotemporal patterns of their occurrence. An ecological time series study was conducted using spatial analysis techniques. WMSD morbidity data from 2007 to 2019 were collected from the Brazilian Information System for Notificable Diseases of the Brazilian Health Informatics Department. Incidence rates were standardized and smoothed using the local empirical Bayes' theorem. Time trends were analyzed by segmented linear regression. Spatial analysis was performed using Moran's univariate global (I) and local (LISA) indexes. The spatiotemporal scan statistic was used to identify high-risk spatiotemporal clusters for WMSD. A total of 93,387 cases of WMSD were recorded in Brazil. Temporal trends showed an increase in all regions except the Northeast, which remained stable. The incidence of WMSD showed a spatial dependence, with spatial and space-time clusters identified, especially in the Southeast region, overlapping the largest economic-industrial center of the country. The spatiotemporal clustering observed in one region suggests the highest level of industrial and economic development. Our findings highlight the need to implement intersectoral surveillance policies, inspect working conditions, and invest in the prevention and promotion of workers' health.

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. Employing population pyramids, crude rates of natural increase, the Mann-Kendall test for trend analysis, and linear regression modeling, the study analyzed vital statistics to forecast demographic trends, with analysis conducted using the R statistical software. Our findings showed a substantial growth of the Yanomami population, yet with a decreasing natural increase rate (τ = -0.33; p = 0.047), suggesting a shift toward population stagnation or decline within the next century. These results call for urgent, coordinated actions to address the complex demographic trends and health challenges faced by Yanomami Indigenous people, ensuring their demographic sustainability and the preservation of their traditional ways of life amidst ongoing environmental and health crises.

Chemsex among men who have sex with men during the Mpox health crisis in Brazil: A nationwide web survey.

OBJECTIVE: To understand the factors associated with the practice of chemsex among MSM in Brazil, especially during the Mpox health crisis, and to design effective prevention and intervention strategies specifically for this population. DESIGN: A cross-sectional and analytical study using an electronic survey, conducted from September to December 2022, during the peak of the Mpox outbreak in Brazil. SAMPLE: A total of 1452 MSM aged 18 and older. MEASUREMENTS: Data were collected via the REDCap platform through a survey with 46 questions. These addressed demographic data, sexual affiliations, practices, experiences with Mpox, healthcare service usage, and stigma or fear related to Mpox. RESULTS: The prevalence of chemsex was 19.42% (n = 282). Multivariate Poisson modeling indicated a high incidence of chemsex among those diagnosed with Mpox and those involved in high-risk behaviors. The practice of chemsex was six times higher among those diagnosed with Mpox (95% CI: 4.73-9.10). MSM who engage in bugchasing had a prevalence twice that of the main outcome (95% CI: 1.31-3.16). CONCLUSION: There is a significant need for targeted interventions for MSM in Brazil, especially given the Mpox outbreak. This study highlights the strong relationships between chemsex, experiences with Mpox, and various sexual behaviors, underscoring the importance of effective public health initiatives.

Impact of the COVID-19 Pandemic Surveillance of Visceral Leishmaniasis in Brazil: An Ecological Study.

The aim of the study was to assess the impact of the COVID-19 pandemic on the notification of new VL cases in Brazil in 2020. It is an ecological and time-series study (2015-2020) with spatial analysis techniques, whose units of analysis were the 5570 Brazilian municipalities. The study population consisted of all new cases of VL recorded between 2015 and 2020. The P-score was calculated to estimate the percentage variation in new VL cases. Global and local univariate Moran's Indices and retrospective space-time scan statistics were used in spatial and space-time analyses, respectively. It was expected that there would be 3627 new cases of VL in Brazil in 2020, but 1932 cases were reported (-46.73%). All Brazilian regions presented a negative percentage variation in the registration of new VL cases, with the Southeast (-54.70%), North (-49.97%), and Northeast (-44.22%) standing out. There was spatial dependence of the disease nationwide in both periods, before and during the first year of the COVID-19 pandemic. There was a significant reduction in the incidence of new VL cases in Brazil during the first year of the COVID-19 pandemic. These findings reinforce the need for better preparedness of the health system, especially in situations of new epidemics.

Intention to use PrEP among men who have sex with men and engage in chemsex: an international descriptive study.

Background: Pre-exposure prophylaxis (PrEP) is a valuable tool in the response to the HIV epidemic, recommended for groups with a higher risk of HIV infection, such as men who have sex with men (MSM), particularly in the context of high-risk sexual behavior such as chemsex. Purpose: This study aimed to analyze the prevalence and factors associated with the intention to use PrEP among MSM who engage in chemsex in Brazil and Portugal. Methods: This was a cross-sectional study of a secondary dataset from a larger study conducted between January 2020 and May 2021 throughout Brazil and Portugal involving 1852 MSM who engage in chemsex. An initial descriptive analysis was performed to calculate the absolute and relative frequencies of independent variables related to the intention to use PrEP among MSM. A multivariate regression model was developed to identify factors independently associated with the intention to use PrEP. Results: Although a high level of PrEP knowledge (85.75%) was observed among MSM who engage in chemsex, the prevalence of intention to use PrEP was only 59.07%. Five variables were associated with a higher prevalence of intention to use PrEP [engaging in double penetration - adjusted prevalence ratio (aPR): 1.56, 95% CI: 1.44-1.69; being assigned female sex at birth - aPR: 1.34, 95% CI: 1.12-1.61; cruising - aPR: 1.21, 95% CI: 1.06-1.38; not using condoms - aPR: 1.20, 95% CI: 1.05-1.36; and being an immigrant - aPR: 1.16; 95% CI: 1.07-1.25], while having knowledge of postexposure prophylaxis (aPR: 0.91; 95% CI: 0.84-0.98), having a casual sexual partner (aPR: 0.86 and 0.85; 95% CI: 0.74-0.99 and 0.74-0.98), and engaging in group sex (aPR: 0.81; 95% CI: 0.73-0.90) were associated with a lower intention to use PrEP. Conclusion: The intention to use PrEP among MSM who engage in chemsex was high, and several factors were associated with this intention. Understanding the factors associated with the intention to use PrEP among MSM practicing chemsex is crucial for developing targeted interventions to increase PrEP uptake in this population. The results of this study suggest that tailored approaches are necessary to promote PrEP use in this population.

Sexual Practices and Predisposition to PrEP Use Among Men Ages 50 Years and Older Who Have Sex With Men: A Cross-Sectional Study.

ABSTRACT: This study aimed to evaluate the sexual practices of men ages 50 years or older who have sex with men (MSM) and factors influencing their predisposition to use preexposure prophylaxis (PrEP). An analytical cross-sectional study was conducted in Brazil and Portugal with 718 MSM. Of these, 278 (38.7%) were categorized as being at high risk for HIV based on the HIV Incidence Risk Index (HIRI), and 418 (58.2%) expressed a predisposition to use PrEP. Overall, sociodemographic factors and specific sexual practices increased the likelihood of being classified as high risk for HIV, particularly sexual position and sexual activity. However, factors that influenced the predisposition to use PrEP included age group, receptive anal sex, knowledge of postexposure prophylaxis, high HIRI score, and a history of syphilis. These findings underscore the urgent need for health services to provide comprehensive and adequate attention to the realities of this population, considering its complexities and specificities.

Pre-exposure prophylaxis among Brazilian men who have sex with men: a comparative study between migrants and non-migrants.

Introduction: Investigating the use and adherence to pre-exposure prophylaxis (PrEP) in MSM is a global health priority in the fight against HIV. Strategies must be capable of increasing usage and reaching not only the population living in the country but also those who immigrate, who face additional vulnerabilities. Based on this, in this observational, cross-sectional, and analytical study, our aim is to analyze the use of PrEP among Brazilian men who have sex with men, whether they are migrants or not. We aim to highlight preventive opportunities and strategies for the global health scenario. Methods: We utilized a sample of Brazilians living in the country and Brazilian immigrants residing in Portugal, one of the main destinations for Brazilians in recent years. To estimate the prevalence ratio (PR) of PrEP use, we employed the Poisson regression model with robust variance estimation using a covariance matrix. Results: A total of 1,117 Brazilian MSM PrEP users participated in this study, with 788 residing in Brazil and 328 in Portugal. Multivariate analysis was conducted in three stages: overall, and for subgroups of residents in Brazil and immigrants in Portugal. We identified four convergent factors that increased the prevalence of PrEP use in Brazilians regardless of migration status: having two or more casual sexual partners per month, engaging in challenging sexual practices as the receptive partner, disclosing serological status on apps, and being single. Among native Brazilians, four unique factors stood out: being in a polyamorous relationship, having sexual relations with unknown casual partners, and having higher levels of education. Discussion: This study highlights the need to implement strategies to strengthen PrEP adherence in Brazil and create international programs that facilitate its usage among populations migrating between these two countries.

Temporal Analysis of Malaria Cases in the Brazilian Yanomami Pediatric Population: A Retrospective Ecologic Study From 2003 to 2022.

This retrospective ecological study investigated malaria incidence among Brazilian Yanomami children and adolescents from 2003 to 2022. Of the 145,573 recorded cases, 75.9% occurred in the Yanomami pediatric population. Moreover, an increase in the proportion of cases among the 10-19 age group has been observed, potentially associated with the recruitment of Indigenous adolescents to mining areas in recent years.

Temporal trend, spatial analysis and spatiotemporal clusters of infant mortality associated with congenital toxoplasmosis in Brazil: Time series from 2000 to 2020.

OBJECTIVE: To analyse the spatial, temporal and spatial-temporal patterns of infant mortality associated with congenital toxoplasmosis in Brazil between the years 2000 and 2020. METHODS: Ecological study of time series, with spatial analysis and spatiotemporal scan of infant mortality associated with congenital toxoplasmosis from the records of deaths of the Mortality Information System of the Brazilian Ministry of Health. The rates were smoothed by the Local Empirical Bayesian model. The Global Moran Index, Global Geary's Contiguity and Getis-Ord General statistics were calculated for spatial autocorrelation assessment. The trends were evaluated by the Joinpoint method. RESULTS: We identified 1183 infant deaths associated with congenital toxoplasmosis in Brazil between 2000 and 2020. The predominant characteristics were male sex (52.1%), post-neonatal age group (51.9%), white race/colour (45.7%), and Southeast region of residence (40.0%). The infant mortality rate associated with congenital toxoplasmosis showed an increasing trend in the country in the years analysed. The spatial analysis showed heterogeneous distribution of mortality in the Brazilian territory and found no evidence of spatial autocorrelation; but spatial-temporal analysis identified three risk clusters involving 703 municipalities. CONCLUSION: Infant mortality associated with congenital toxoplasmosis is a persistent public health problem in Brazil. The risk factors male sex, indigenous race/colour, early neonatal age, North and Northeast regions and risk clusters mapped in this study should be observed for future analysis and planning of health care policies in the control of infant deaths associated with congenital toxoplasmosis. Health surveillance strategies and public health policies need to be strengthened.

Adherence to Pre-Exposure Prophylaxis (PrEP) among Men Who Have Sex with Men (MSM) in Portuguese-Speaking Countries.

Strengthening strategies to improve adherence to the use of pre-exposure prophylaxis (PrEP) in key populations constitutes a global health priority to be achieved across countries, especially in countries that share a high flow of people such as Brazil and Portugal. This study aimed to analyze the factors associated with adherence to PrEP among MSM from two Portuguese-speaking countries, highlighting the opportunities and preventive strategies for the global health scenario. This was a cross-sectional analytical online survey conducted from January 2020 to May 2021 with MSM in Brazil and Portugal. For analysis of the data, the Poisson regression model was used to estimate the prevalence ratio (PR) for developing a model to evaluate the associated factors in both countries in a comparative and isolated way. Adherence to PrEP use corresponded to 19.5% (n = 1682) of the overall sample: 18.3% (n = 970) for Brazil and 21.5% (n = 712) for Portugal. Having more than two sex partners in the last 30 days (aPR: 30.87) and routinely undergoing HIV tests (aPR: 26.21) increased the use of this medication. Being an immigrant (PR: 1.36) and knowing the partner's serological status (PR: 1.28) increased adherence to PrEP in Portugal, whereas, in Brazil, it was being an immigrant (PR: 0.83) and not knowing the serological status (PR: 2.24) that promoted the use of this medication. Our findings reinforce the need to invest in programs and strategies to improve access and adherence to PrEP, especially in key populations.

Knowledge, Attitude and Practices towards the Prevention of Schistosomiasis Mansoni in an Endemic Area of Alagoas, Northeast Brazil.

We analyzed the knowledge, attitudes and practices (KAP) of schistosomiasis mansoni prevention in an endemic area of Brazil. This cross-sectional study was conducted between March and May 2021, with 412 participants living in the municipality of Feira Grande, Alagoas, Brazil. Data collection occurred through visits to the Health Center Urbano II and Massapê, through an interview with a structured questionnaire to identify the levels of KAP regarding schistosomiasis prevention. Of all respondents, 70.87% lived in rural areas, 22.66% reported a history of past schistosomiasis and 52.71% never participated in schistosomiasis control program actions. Factors associated with better KAP scores were being part of an older age group, not using rainwater and having no history of past schistosomiasis. Specifically, among the domains, attitude was the highest score and knowledge was the lowest. Participation in a health intervention program, knowing someone who had schistosomiasis and having been informed through a public health program seemed to have an important impact on the population's KAP. Our results contributed to broadening perceptions about schistosomiasis prevention, highlighting the positive impacts that health programs and interventions have on disease control.

Determinants of sexual exposure to HIV in Portuguese and Brazilian adolescents: a path analysis. / Fatores determinantes da exposição sexual ao HIV em adolescentes luso-brasileiros: uma análise de caminhos.

OBJECTIVE: to analyze the direct and indirect effects of determinants of sexual exposure to the human immunodeficiency virus among male adolescents who have sex with men and the implications for nursing care. METHOD: cross-sectional study carried out with 578 Portuguese and Brazilian adolescents aged 18 and 19. Interrelationships of conjugal status, use of dating apps, practice of chemsex, unawareness, partner credibility, challenging sexual practices and ineffective forms of protection against sexual exposure to the human immunodeficiency virus were evaluated using the Path Analysis technique. RESULTS: significant direct effect on sexual exposure to the human immunodeficiency virus: conjugal status (ß=-0.16), use of apps (ß=-0.30), challenging sexual practices (ß=0.48) and ineffective forms of protection (ß=0.35). Indirect paths: partner credibility influenced ineffective forms of protection (ß=0.77); having a steady/polyamorous relationship influenced the use of dating apps (ß=-0.46); chemsex, mediated by challenging sexual practices (ß=0.67), determined greater sexual exposure. CONCLUSION: adolescent sexual behaviors and forms of amorous/sexual relationship must be considered in nursing care planning to reduce sexual exposure to the human immunodeficiency virus.(1) Adolescents present high prevalence (81.0%) of sexual exposure to HIV. (2) Specificities of sexual practices are determinant factors of sexual exposure. (3) The higher the credibility given to a partner, the higher the sexual exposure to HIV. (4) Challenging sexual practices (such as fisting) determine sexual exposure. (5) Nursing care must focus on lowering exposure to HIV.

Influence of Sociodemographic and Emotional Factors on the Relationship between Self-Compassion and Perceived Stress among Men Residing in Brazil during the COVID-19 Pandemic.

The analysis of sociodemographic and emotional factors is essential to understanding how men perceive stress and practice self-compassion. In health crises, this problem becomes an emergency for public health. This study aimed to analyze the influence of sociodemographic and emotional factors on the relationship between self-compassion and the perceived stress of men residing in Brazil during the COVID-19 pandemic. This is a nationwide cross-sectional study carried out between June and December 2020 with 1006 men who completed a semi-structured electronic questionnaire. Data were collected using the snowball technique. Perceived stress was measured by the Perceived Stress Scale (PSS-14), and self-compassion was assessed using the Self-Compassion Scale. Most men had low self-compassion (51.5%; n = 516) and a moderate level of perceived stress (60.9%; n = 613), while 15.9% (n = 170) had a high level of stress. The prevalence of men in the combined situation of low self-compassion and high perceived stress was 39.4% (n = 334). Living with friends had a higher prevalence of low self-compassion and high perceived stress. The prevalence of common mental disorders was high (54.3%). Men with low levels of self-compassion reported higher levels of perceived stress; however, this association was moderated by emotional and sociodemographic variables. These findings highlight the importance of considering individual and contextual factors in public policies promoting men's mental health.
