Massive Education in Prison Health in Brazil: A Look Beyond the Walls

Equal access to health initiatives and services under the principles of universal and comprehensive care remains a challenge in Brazil. The realization of public health policies is further intricate when one examines the health situation of people deprived of liberty. This study showcases the "Prison System: Beyond the Walls" educational pathway, available on the Virtual Learning Environment of the Brazilian National Health System (AVASUS). The action research methodological strategy guided the pathway development, emphasizing dialogic learning. The goal was to address the need for massive training on the topic of prison health, with the model focusing on engagement through spontaneous, non-mandatory participation in the pathway courses. The pathway comprised four modules, whose educational offerings were based on the self-learning model. Students were free to choose which courses to take and in what order, as there was no prerequisite for participating in modules. Hence, students could either take all the courses or only those with which they identify their learning needs, regardless of work demands or personal interests. Structuring the pathway through action research facilitated a massive, cohesive, and continuous training process. This approach expanded knowledge and established meaningful relationships among the related topics and the key players involved: health professionals, prison officers, and people deprived of liberty. Notably, the pathway courses have surpassed the 50,000-enrollment mark, spanning all five regions of Brazil. In this context, this article presents and discusses the development of the "Prison System: Beyond the Walls" pathway, emphasizing the massive improvement of health within Brazil's prison system and highlighting the results achieved.

Disparities in Syphilis Trends and the Impact of the COVID-19 Pandemic: A Joinpoint Analysis of Florida Surveillance Data (2013-2022)

INTRODUCTION

Syphilis, a sexually transmitted infection caused by the bacterium ​​​​​​Treponema pallidum, has reemerged at an increasing rate globally in recent years, posing a significant public health concern. Visualizing and analyzing time series trends of syphilis across various demographics and geographic regions, and how syphilis trends varied during the pandemic coronavirus disease 2019 (COVID-19), would help public health policymakers develop targeted strategies and interventions to effectively address the rising rates of syphilis, ultimately improving overall public health outcomes.

METHODS

 A retrospective study was conducted using surveillance data on infectious syphilis cases reported to the Florida Department of Health, between 2013 and 2022. Age-standardized syphilis rates (ASSRs) per 100,000 persons were calculated using the 2000 U.S. standard population data. The average annual percentage change (AAPC) in the ASSRs was analyzed according to age, gender, race, geographic locations, and the COVID-19 pandemic period to quantify the epidemiological syphilis trends using joinpoint regression models.

RESULTS

 In Florida, the ASSR significantly increased from 8.65/100,000 in 2013 to 23.08/100,000 in 2022 across different demographic groups, with an overall AAPC of 11.47 (95% confidence interval (CI): 9.85-13.43). This increase in the AAPC was more pronounced in females (AAPC = 20.97; 95% CI, 18.61-24.49) than in males (AAPC = 10.34; 95% CI, 8.19-12.98). The increasing trends of infectious syphilis were observed across all age groups, with greater increases among those aged 25-49 years (AAPC = 12.32; 95% CI, 10.09-15.18), aged 50-69 years (AAPC = 13.42; 95% CI, 9.41-18.89), and aged over 70 years (AAPC = 13.63; 95% CI, 9.23-21.95), compared to those aged less than 24 years (AAPC = 7.86; 95% CI, 7.06-8.81). The increasing trends were comparable across racial groups, with an AAPC of 8.08 (95% CI, 5.47-11.15) for Hispanics, 11.84 (95% CI, 10.02-14.09) for non-Hispanic Whites, 10.49 (95% CI, 8.75-12.66) for non-Hispanic Blacks, and 11.29 (95% CI, 5.28-19.57) for non-Hispanic individuals of other races, respectively. The AAPC for the COVID-19 pandemic period was 12.99 (95% CI, 8.48-16.21), which was comparable to the pre-pandemic period (AAPC = 11.58; 95% CI, 10.17-12.76), indicating that this upward trend in infectious syphilis persisted throughout the COVID-19 pandemic. At the county level, over the 10-year period, the average ASSRs ranged from 0.89/100,000 in 2013 to 25.41/100,000 in 2022, with the estimated AAPCs varied from 2.47 (95% CI, -1.89 to 6.92) in Monroe County to 50.01 (95% CI, 37.71-62.27) in Okaloosa County.

CONCLUSIONS

 The trend of infectious syphilis increases substantially from 2013 to 2022, with notable differences observed among age, gender, and geographic regions in Florida. Females experienced a greater rise in infectious syphilis cases compared to males. This upward trend in infectious syphilis persisted throughout the COVID-19 pandemic. Efforts are needed to implement strategies to address the rising syphilis rates within high-incidence groups and communities across the state.

Seroprevalence of Treponema pallidum infection among high-risk populations from Brazil

Syphilis is a significant public health concern worldwide. According to the 2020 estimates, nearly 7.1 million new cases of syphilis have been reported globally, with over 30 % of these cases reported from American nations, particularly Brazil. Concerns have been raised regarding the susceptibility of specific groups to syphilis due to challenges and vulnerabilities that place these groups at a higher risk of infections or complications in the treatment outcomes. The present study aimed to compare the seroprevalence and the factors associated with syphilis among such high-risk groups. The study was designed as a cross-sectional one and was conducted with pregnant women, people living with HIV (PLHIV), people living with tuberculosis (PLTB), indigenous and healthy populations in Mato Grosso do Sul, Brazil. The study was conducted between June 2019 and August 2022, during which the included patients were subjected to treponemal and non-treponemal serological assays. The study also included a survey conducted through a self-reported questionnaire to collect information regarding the participants' demographics and sexual behaviors. A total of 550 samples were collected, with 110 participants in each of the five groups. The results of the study revealed that the seroprevalence of Treponema pallidum infection in pregnant women, PLHIV, PLTB, indigenous and healthy populations of the study region was 10 % (n = 11/110), 41.81 % (n = 46/110), 17.27 % (n = 19/110), 5.45 % (n = 6/110), and 8.18 % (n = 9/110), respectively. Homosexual orientation (p = 0.04) and a history of sexually transmitted infection (STI) (p = 0.01) were associated with the seroprevalence of T. pallidum infection in PLHIV. However, no such associations were noted in the remaining four groups. The seroprevalence of T. pallidum infection was observed to vary significantly among the different high-risk groups, which highlighted the persistent concern of syphilis, particularly among vulnerable populations. These findings underscore the significance of focused interventions and public health strategies customized to the specific requirements of each of the groups evaluated in the present study to decrease the number of cases of syphilis and thereby prevent future complications in patients with other serious infections.

The rules of mature sex: Sexual scripts and the global challenge of rising STIs

Sexual health continues to be a socially complex problem globally with rising rates of sexually transmitted infections (STIs) despite extensive government and health marketing initiatives. In particular, STIs are rising at a greater rate in mature consumers than any other age group with the main reason cited as lack of condom use. The rules around condom use are based on sexual scripts or internalised guidelines and thus a key step in developing social marketing initiatives to increase condom use and address this global challenge is identifying the sexual scripts that motivate and inhibit condom use by mature consumers. Using sexual script theory, this research involves interviews with 24 mature single heterosexual Australian consumers to identify the sexual scripts that can be leveraged in health marketing to address the grand challenge of increasing mature consumer participation in protective sexual health behaviours.

Temporal Trends in Syphilis Incidence among Men with HIV in Busan, Korea, 2005-2022: A Retrospective Cohort Study

We aimed to assess the temporal trends of incident syphilis and its associated risk factors among men with HIV (Human Immunodeficiency Virus) in Korea during the COVID-19 pandemic. We conducted a retrospective cohort study of men with HIV attending an HIV clinic in Korea between 2005 and 2022. Of 767 men with HIV, 499 were included and contributed 3220 person-years (PY) of the observation period. Eighty-two patients were diagnosed with incident syphilis, with an overall incidence of 2.55/100 PY (95% confidence interval [CI] 20.56-31.53). The incidence of syphilis per 100 PY gradually decreased from 2.43 (0.79-7.42) in 2005-2007 to 1.85 (1.08-3.17) in 2014-2016; however, it increased to 3.0 (1.99-4.53) in 2017-2019, and further to 3.33 (2.26-4.89) in 2020-2022. A multivariate analysis identified young age (≤30 years versus >50, adjusted HR 6.27, 95% CI 2.38-16.56, p < 0.001), treponemal test positive at baseline (2.33, 1.48-3.67, p < 0.001), men who have sex with men (2.36, 1.34-4.16, p = 0.003), and history of incarceration (2.62, 1.21-5.67, p = 0.015) as risk factors for incident syphilis. Recently, syphilis incidence in men with HIV has increased in Korea, especially in young patients and at-risk groups, highlighting the need for enhanced regular screening and targeted behavioral interventions among these populations.

Evaluating the global, regional, and national impact of syphilis: results from the global burden of disease study 2019

Syphilis is a global public health concern. This study aimed to assess the global and regional burden of syphilis from 1990 to 2019. Disease burden was evaluated using disability-adjusted life-years (DALYs) and prevalence. Data were extracted from the 2019 global burden of disease Study, an open database available for download. Age-standardized rates (ASR) and estimated annual percentage changes (EAPC) were calculated to evaluate the syphilis burden over time. In 2019, the total number of prevalent cases of syphilis was 49.71 million worldwide. The ASR of prevalence was stable from 1990 to 2019 with an EAPC of 0.00 (95% CI - 0.10-0.11). The number of DALYs caused by syphilis was 7.36 million in 2019, reflecting a reduction of 16.38% compared with that in 1990 (8.80 million). The ASR of DALYs exhibited a decreasing trend from 1990 to 2019 (EAPC =  - 1.01; 95% CI - 1.19 to - 0.84), with the highest rates observed in the younger age group (< 14 years old). In 2019, the highest ASR of DALYs was found in low sociodemographic index (SDI) regions (239.21/100,000), and the lowest in high SDI regions (3.14/100,000). Generally, the ASR of DALYs decreased as the SDI increased. The top three countries with the highest ASR of DALYs for syphilis were the Solomon Islands, Equatorial Guinea, and Liberia. While the global prevalence of syphilis remained persistently high from 1990 to 2019, there has been a recent decrease in the ASR of DALYs. Increased attention should be dedicated to younger populations and regions characterized by low SDIs.
