The leading role of expert safety knowledge in supporting the mission of caring for patients during man-made and natural disasters: state of emergency medicine in Ethiopia, Myanmar, and Ukraine.

Preparedness to endure extreme situations such as natural disasters or military conflicts is not commonplace in healthcare training programs. Moreover, multidisciplinary teams in health services rarely (if ever) include experts in security. However, when emergency situations occur, prevailing healthcare demands do not cease to exist, and unexpected demands often surge due to the shortage of other services and supplies or as a consequence of the emergency condition itself.With services in 45 countries, AIDS Healthcare Foundation (AHF) has operated in several conflict zones, facing broad and challenging security demands. Since 2017 AHF has implemented the Global Department of Safety and Security (GDSS), a dedicated intelligence and safety program that had a key role in the security monitoring, preparedness, and defense responses, assisting staff members and clients during recent conflicts.In this manuscript, we describe the experience of AHF's GDSS in three recent military conflicts in Ethiopia, Myanmar, and Ukraine, and provide insights into steps that can be taken to assure staff safety and support the mission of caring for patients throughout catastrophic events.

Safeguarding HIV prevention and care services amidst military conflict: experiences from Ukraine.

Ukraine stands out among European countries concerning HIV epidemiological data. Since February 2022, the military conflict with Russian forces has posed unprecedented challenges to HIV prevention and care. AIDS Healthcare Foundation (AHF), a global non-profit organisation with operations in Ukraine since 2009, implemented a preparedness plan to protect staff members and support local facilities in the continuity of care throughout the war. In this manuscript, we describe the strategies adopted by AHF to anticipate the risk of military conflict, steps to implement a preparedness plan, main challenges faced by local staff members and managers, adaptations needed as the conflict evolved, and indicators of HIV care 1 year before and 1 year after the onset of the conflict. Our experience shows that safeguarding the organisation's human resources has been a prerequisite to sustain services throughout the war.

Brazilian Clinical Practice Guidelines for Sexually Transmitted Infections That Cause Urethral Discharge: Assessment According to the AGREE II and Critical Analysis Based on the WHO Recommendations.

BACKGROUND: Sexually transmitted infections (STI) can have severe consequences. In Brazil, case management is recommended by the Clinical Protocol and Therapeutical Guidelines for Comprehensive Care for People with STIs (PCDT-IST). This study assessed the quality of PCDT-IST (2021) and reviewed the main recommendations for the management of STI that cause urethral discharge compared with the World Health Organization (WHO) STI Guidelines. METHODS: The PCDT-IST (2021) quality was independently assessed by 4 appraisers using the Appraisal of Guidelines Research and Evaluation instrument, version II (AGREE II). The PCDT-IST (2021) and the WHO Guidelines for the Management of Symptomatic STI (2021) were compared considering 14 different assessment domains. RESULTS: The PCDT-IST (2021) scores in the AGREE II domains were: Rigor of Development (58%), Applicability (35%), Editorial Independence (38%), Scope and Purpose (78%), Stakeholder Involvement (74%), and Clarity and Presentation (82%). The overall score was 67%, and all appraisers recommended the Brazilian guideline. Regarding the PCDT-IST (2021) and the WHO STI Guidelines (2021) comparation, 10 domains would be relevant for further reviewing the Brazilian recommendations: Diagnostic tests; Etiological approach; Treatment for recurrent urethral discharge; Treatment for urethritis without etiological agent identification; Treatment for gonococcal urethritis; Treatment for chlamydial urethritis; Retreatment for gonococcal infections; Treatment for Mycoplasma genitalium urethritis; Treatment for Trichomonas vaginalis urethritis; 10. Flowcharts. CONCLUSIONS: The PCDT-IST (2021) has a reasonable degree of quality. However, the domains of Applicability, Rigor of Development, and Editorial Independence must be better ensured. The guidelines comparison will help to select key topics that should be addressed with priority in the following national STI guidelines updates.

Assessment of the Accuracy, Usability and Acceptability of a Rapid Test for the Simultaneous Diagnosis of Syphilis and HIV Infection in a Real-Life Scenario in the Amazon Region, Brazil.

We field-assessed the accuracy, acceptability, and feasibility of the SD BIOLINE HIV/Syphilis Duo rapid diagnostic test in three groups: pregnant women, female sex workers (FSW), and men who have sex with men (MSM). Venous blood samples collected in the field were compared with the respective gold standard methods: SD BIOLINE HIV/Syphilis Duo Treponemal Test versus FTA-abs (Wama brand) treponemal laboratory test for syphilis, and SD BIOLINE HIV/Syphilis Duo Test versus the fourth generation Genscreen Ultra HIV Ag-Ag (Bio-Rad brand) laboratory test for HIV. From a total of 529 participants, 397 (75.1%) were pregnant women, 76 (14.3%) FSW and 56 (10.6%) MSM. Sensitivity and specificity parameters of HIV were 100.0% (95% CI: 82.35-100.0%) and 100.0% (95% CI: 99.28-100.0%), respectively. Sensitivity and specificity parameters found for TP antibody detection were 95.00% (95% CI: 87.69-98.62%) and 100.0% (95% CI: 98.18-100.0%), respectively. The SD BIOLINE HIV/Syphilis Duo Test showed high acceptability among participants (85.87%) and health professionals (85.51%), as well as easy usability by professionals (91.06%). The usability of the SD BIOLINE HIV/Syphilis Duo Test kit would not be a barrier to accessing rapid testing, if the product were incorporated into the list of health service supplies.

Implementing a provisional overarching intervention for COVID-19 monitoring and control in the Brazil-Colombia-Peru frontier.

Introduction: he challenge was to provide comprehensive health resources to a remote and underserved population living in the Brazil-Colombia-Peru border, amid the most disruptive global crisis of the century. Methods: In August 2021, Fundação Oswaldo Cruz Amazonia (FIOCRUZ Amazônia) and partner collaborators implemented an overarching provisional program for SARS-CoV-2 detection and lineages characterization, training of laboratory personnel and healthcare providers, donation of diagnostic supplies and personal protective equipment, and COVID-19 vaccination. The expedition was conducted at the Port of Tabatinga, a busy terminal with an intense flux of people arriving and departing in boats of all sizes, located in the Amazon River basin. Local government, non-profit organizations, private companies, and other stakeholders supported the intervention. Results: The expedition was accomplished in a convergence point, where migrant workers, traders, army personnel, people living in urban areas, and people from small villages living in riversides and indigenous territories are in close and frequent contact, with widespread cross-border movement. Using a boat as a provisional lab and storage facility, the intervention provided clinical and laboratory monitoring for 891 participants; vaccination for 536 individuals; personal protective equipment for 200 healthcare providers; diagnostic supplies for 1,000 COVID-19 rapid tests; training for 42 community health agents on personal protection, rapid test execution, and pulse oximeter management; and hands-on training for four lab technicians on molecular diagnosis. Discussion: Our experience demonstrates that multilateral initiatives can counterweigh the scarcity of health resources in underserved regions. Moreover, provisional programs can have a long-lasting effect if investments are also provided for local capacity building.

Behavioral factors associated with multiple-type HPV genital infections: data from a cross-sectional study in young women in Brazil.

OBJECTIVES: To investigate the pattern of multiple human papillomavirus (HPV) infections and associated factors in young women who access the Brazilian public health care system to better understand the characteristics of multiple HPV infections, a critical issue in this era of multivalent vaccines. METHODS: This was a cross-sectional, multicenter study with sexually active unvaccinated women (16-25 years old) from 119 primary Brazilian healthcare centers between September 2016 and November 2017. Cervical samples were collected by trained health professionals, and HPV detection was performed in a central laboratory by Linear Array. RESULTS: Of the 5268 women, 33.00% (95% CI 31.07-34.92) had multiple infections. At least one type of high-risk HPV was present in 85.50% of all multiple infections. All HPV types were detected more frequently in association with other types than alone. Young individuals who were single or in a casual relationship and those who had more than one sexual partner in the past year were more likely to have multiple infections. CONCLUSIONS: In this work, a high rate of multiple HPV infections among unvaccinated young adults tended to increase due to certain risk factors. Such data can provide insight for decision makers in the development of public policies regarding HPV prevention.

Understanding the characteristics of multiple infections is critical in the era of HPV multivalent vaccines for the prevention of cervical carcinomas. Therefore, in this cross-sectional study, we aimed to investigate the pattern of multiple HPV infections and associated factors in 5,268 sexually active unvaccinated women (16­25 years old) who access the Brazilian public health care system. Cervical samples were collected by trained health professionals, and HPV detection was performed in a central laboratory by Linear Array. A total of 33.00% (95% CI 31.07­34.92) had multiple infections (60.43% of the HPV-positive sample). The number of HPV types in a multiple infection ranged from 2 to 14 different types. The viral types more frequently identified were HPV 16 and 52. All HPV types were detected more frequently in association with other types than alone. The incidence of multiple infections was 1.29 times higher in single than in married or cohabitating participants. Women who had two or more partners in the last year also had higher rates of multiple infections than those who had fewer than two sexual partners. In conclusion, a high prevalence of multiple infections prior to the national HPV immunization program was observed, especially with the increase in less safe behavior factors.

Modeling the epidemiological impact of the UNAIDS 2025 targets to end AIDS as a public health threat by 2030.

BACKGROUND: UNAIDS has established new program targets for 2025 to achieve the goal of eliminating AIDS as a public health threat by 2030. This study reports on efforts to use mathematical models to estimate the impact of achieving those targets. METHODS AND FINDINGS: We simulated the impact of achieving the targets at country level using the Goals model, a mathematical simulation model of HIV epidemic dynamics that includes the impact of prevention and treatment interventions. For 77 high-burden countries, we fit the model to surveillance and survey data for 1970 to 2020 and then projected the impact of achieving the targets for the period 2019 to 2030. Results from these 77 countries were extrapolated to produce estimates for 96 others. Goals model results were checked by comparing against projections done with the Optima HIV model and the AIDS Epidemic Model (AEM) for selected countries. We included estimates of the impact of societal enablers (access to justice and law reform, stigma and discrimination elimination, and gender equality) and the impact of Coronavirus Disease 2019 (COVID-19). Results show that achieving the 2025 targets would reduce new annual infections by 83% (71% to 86% across regions) and AIDS-related deaths by 78% (67% to 81% across regions) by 2025 compared to 2010. Lack of progress on societal enablers could endanger these achievements and result in as many as 2.6 million (44%) cumulative additional new HIV infections and 440,000 (54%) more AIDS-related deaths between 2020 and 2030 compared to full achievement of all targets. COVID-19-related disruptions could increase new HIV infections and AIDS-related deaths by 10% in the next 2 years, but targets could still be achieved by 2025. Study limitations include the reliance on self-reports for most data on behaviors, the use of intervention effect sizes from published studies that may overstate intervention impacts outside of controlled study settings, and the use of proxy countries to estimate the impact in countries with fewer than 4,000 annual HIV infections. CONCLUSIONS: The new targets for 2025 build on the progress made since 2010 and represent ambitious short-term goals. Achieving these targets would bring us close to the goals of reducing new HIV infections and AIDS-related deaths by 90% between 2010 and 2030. By 2025, global new infections and AIDS deaths would drop to 4.4 and 3.9 per 100,000 population, and the number of people living with HIV (PLHIV) would be declining. There would be 32 million people on treatment, and they would need continuing support for their lifetime. Incidence for the total global population would be below 0.15% everywhere. The number of PLHIV would start declining by 2023.

Brazilian Protocol for Sexually Transmitted Infections 2020: acquired syphilis.

The Clinical Protocol and Therapeutic Guidelines for Comprehensive Care of People with Sexually Transmitted Infections, published by the Brazilian Ministry of Health in 2020, includes updates concerning acquired syphilis. The document comprises rapid test use, safety and efficacy of benzathine benzylpenicillin, case follow-up, neurosyphilis clinical and laboratory management, approaching sex partners, assistance and monitoring of diagnosed pregnant women, and syphilis and HIV co-infection specificities, as well as a case notification summary. Health managers and professionals must be continuously trained so as to integrate care and surveillance, to strengthen actions for efficient control of syphilis, to broaden the search for sex partners, and to expand access of most vulnerable populations to health services. Most people with syphilis are asymptomatic; this contributes to the maintenance of the transmission chain. Without adequate treatment of pregnant women with syphilis, severe consequences can occur, such as miscarriage, prematurity, low birth weight, natimortality, and congenital syphilis.

Prevalence of HPV infection among sexually active adolescents and young adults in Brazil: The POP-Brazil Study.

For Brazil, there are no nationwide data on HPV prevalence against which the impact of the HPV immunization program can be measured in the future. Therefore, we aim to evaluate the prevalence of genital HPV infection among adolescents and young adults in Brazil. A cross-sectional, multicentric, nationwide survey was conducted between September 2016 and November 2017. Sexually active unvaccinated women and men aged 16 to 25 years old were recruited from 119 public primary care units, including all 26 state capitals and the Federal District. All participants answered a face-to-face interview and provided biological samples for genital HPV analysis. We used an automated DNA extraction method and HPV genotyping was performed using the Linear Array genotyping test (Roche). Of 7,694 participants, 53.6% (95% CI 51.4-55.8) were positive for any HPV type. The prevalence of high-risk HPV types was significantly higher in women (38.6% vs. 29.2%, P < 0·001). The HPV types included in the quadrivalent vaccine were detected in 1002 (14.8%) specimens, with a different pattern of HPV infection between sexes. Characteristics associated with overall HPV detection included female gender, self-declaration of race as brown/pardo, lower socioeconomic class, single or dating, current smoking and having 2 or more sex partners in the past year. We found a high prevalence of HPV, with significant differences between regions. Our data provide information that may be considered when developing HPV prevention policies and constitute a baseline against which the impact of the HPV immunization program in Brazil can be measured in future years.

HCV genotype profile in Brazil of mono-infected and HIV co-infected individuals: A survey representative of an entire country.

INTRODUCTION: To be eligible for government-provided treatment in Brazil, all HCV-infected individuals are required to be genotyped shortly after diagnosis. We describe the HCV genotype (G) profiles by geographic region, gender, age and HIV co-infection. METHODS: We assessed 29,071 genotypes collected from HCV-infected individuals from March 2016 to March 2018 (Abbott Real-Time HCV Genotype). We randomly selected 12,336 samples for HIV co-infection testing using an EIA rapid test kit (TR DPP HIV 1/2 Bio-Manguinhos). Descriptive statistical analyses were performed using R. RESULTS: Overall, HCV genotype distribution was 40.9% G1A, 30.2% G1B, 23.8% G3, 3.8% G2, 0.7% G4, 0.1% G5 and 0.6% with multiples genotypes. G1A prevalence was 44.4% among males and 35.8% among females. G1B and G2 were more prevalent in older individuals than G1A and G3. G3 was more prevalent in the South region. Of samples tested for HIV co-infection, 15% were HIV+. Median age among HCV/HIV co-infected individuals was 50 years old compared to 57 years old among mono-infected individuals. Distinct HCV genotype prevalence between HCV/HIV co-infected and HCV mono-infected individuals were respectively: G1A 60.6% versus 37.8%, G1B 15.2% versus 32.9%, and G3 18.9% versus 24.7%. G4 was detected among co-infected young men (3.5% versus 0.2% among mono-infected). CONCLUSION: The increasing prevalence of G3, as inferred by the younger ages of the HCV-infected individuals, poses an extra challenge with regards to disease progression. Distinct genotypical profiles between HCV mono-infection and HCV/HIV co-infection warrant future research in order to better understand and help mitigate HCV chains of transmission.

Adequacy of prenatal care, diagnosis and treatment of syphilis in pregnancy: a study with open data from Brazilian state capitals / Adequação de atendimento pré-natal, diagnóstico e tratamento da sífilis gestacional: um estudo com dados abertos de capitais brasileiras / Adecuación de la atención prenatal, diagnóstico y tratamiento de la sífilis en el embarazo: un estudio con datos abiertos en siete capitales brasileñas

Abstract: To assess the adequacy of prenatal care offered in the Brazilian capital cities and the diagnosis of gestational syphilis through public data from health information systems. The modified Kotelchuck index for adequacy of prenatal care was built using Brazilian Information System on Live Births (SINASC) data. Data on gestational syphilis, congenital syphilis, estimated population coverage by the Family Health Strategy (FHS), the Municipal Human Development Index (MHDI) and data from National Program for Access and Quality Improvement in Primary Care (PMAQ-AB) were accessed in public sites. The profile of pregnant women associated with inadequate care was assessed by logistic regression. In total, 685,286 births were analyzed. Only 2.3% of women did not attend prenatal appointments. The mean adequacy was 79.7%. No correlation was found between adequacy of prenatal care and FHS coverage (p = 0.172), but a positive correlation was found with the MHDI (p < 0.001). Inadequacy of prenatal care was associated with age below 20 years old, schooling less than 4 years, non-white skin color and not having a partner. Among the congenital syphilis cases, 17.2% of mothers did not attend prenatal care. Gestational syphilis more often affected vulnerable women, including a higher proportion of adolescents, women with low schooling, and women of non-white color. The PMAQ-AB showed a median availability of 27.3% for syphilis rapid tests, 67.7% for benzathine penicillin, and 86.7% for benzathine penicillin administration by health teams. The use of public data showed a low adequacy of prenatal care in Brazilian capitals, denoting insufficient quality for the diagnosis and treatment of gestational syphilis, despite the availability of supplies. Continuous monitoring can be carried out using public data, indicating to local strategies to eliminate congenital syphilis.

Resumo: O estudo buscou avaliar a adequação do atendimento pré-natal oferecido nas capitais brasileiras e o diagnóstico da sífilis gestacional através de dados públicos dos sistemas de informação de saúde. Foi construído o indicador de Kotelchuck modificado para adequação do atendimento pré-natal, usando dados do Sistema de Informações sobre Nascidos Vivos (SINASC). Foram acessados em sites públicos os dados sobre sífilis gestacional, sífilis congênita, estimativa da cobertura populacional pela Estratégia Saúde da Família (ESF), Índice de Desenvolvimento Humano (IDH) municipal e dados do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica (PMAQ-AB). O perfil das gestantes associado ao atendimento inadequado foi avaliado com base na regressão logística. Foram analisados um total de 685.286 nascimentos. Apenas 2,3% das mulheres não receberam atendimento pré-natal. A taxa média de adequação foi de 79,7%. Não foi encontrada correlação entre a adequação do pré-natal e a cobertura pela ESF (p = 0,172), mas houve correlação com o IDH municipal (p < 0,001). A inadequação da assistência pré-natal mostrou associação com a idade < 20 anos, escolaridade < 4 anos, raça/cor não-branca e situação conjugal sem companheiro. Entre os casos de sífilis congênita, 17,2% das mães não haviam recebido atendimento pré-natal, e a sífilis gestacional afetava mais as gestantes vulneráveis, incluindo uma proporção maior de adolescentes, mulheres com baixa escolaridade e mulheres não brancas. O PMAQ-AB mostrou uma disponibilidade mediana de 27,3% de testes rápidos para sífilis, 67,7% para penicilina benzatina e 86,7% para administração de penicilina benzatina pela equipe de saúde. O uso de dados públicos revelou baixa adequação do atendimento pré-natal nas capitais brasileiras, denotando qualidade insuficiente para o diagnóstico e tratamento da sífilis gestacional, apesar da disponibilidade de insumos. O monitoramento contínuo pode ser realizado com o uso de dados públicos, indicando estratégias locais para eliminar a sífilis congênita.

Resumen: El objetivo de este trabajo ha sido evaluar la adecuación de la atención prenatal que se ofreció en capitales brasileñas, y el diagnóstico de sífilis gestacional, mediante datos públicos de los sistemas de información de salud. El indicador modificado de Kotelchuck para la adecuación de la atención prenatal se construyó usando datos del Sistema de Información sobre Nacidos Vivos (SINASC). La información sobre sífilis gestacional, sífilis congénita, así como la cobertura de población estimada por la Estrategia Salud de Familia (ESF), Índice de Desarrollo Humano (IDH) municipal y datos del Programa Nacional para el Acceso Mejorado y Calidad de la Atención Básica (PMAQ-AB) se recabaron de sitios web públicos. El perfil de las mujeres embarazadas asociado con el cuidado inadecuado fue evaluado mediante regresión logística. En total, se analizaron 685.286 nacimientos. Solamente un 2,3% de las mujeres no atendieron a citas prenatales. La adecuación media fue de un 79,7%. No se encontró correlación entre la adecuación del cuidado prenatal y la cobertura de la ESF (p = 0,172), pero se encontró una correlación positiva con el MHDI (p < 0,001). La inadecuación del cuidado prenatal estuvo asociada con una edad < 20 años, escolaridad < 4 años, raza no blanca y no tener pareja. Entre los casos de sífilis congénita, un 17,2% de las madres no asistieron a la atención prenatal. La sífilis gestacional afectó más a menudo a las mujeres vulnerables, incluyendo una más alta proporción de adolescentes, mujeres con baja escolaridad, y mujeres de color no blanco. La PMAQ-AB mostró un promedio de disponibilidad de un 27,3%, en el caso de test rápidos de sífilis, un 67,7% para la penicilina benzatínica, y un 86,7% para la administración penicilina benzatínica por equipos de salud. El uso de los datos públicos mostró una baja adecuación del cuidado prenatal en capitales brasileñas, denotando una insuficiente calidad para el diagnóstico y tratamiento de la sífilis gestacional, a pesar de la disponibilidad de suministros. La supervisión continua se puede llevar a cabo usando datos públicos, apuntando a estrategias locales para eliminar la sífilis congénita.

Impact on mortality of being seropositive for hepatitis C virus antibodies among blood donors in Brazil: A twenty-year study.

INTRODUCTION: Hepatitis C virus (HCV) infection is a major health problem associated with considerable risk of mortality in different regions of the world. The purpose of this study was to investigate the contribution of HCV infection on all-cause and liver-related mortality, in a large cohort of blood donors in Brazil. METHODS: This is a retrospective cohort study of blood donors from 1994 to 2013, at Fundação Pró-Sangue-Hemocentro de São Paulo (FPS). This cohort included 2,892 and 5,784 HCV antibody seropositive and seronegative donors, respectively. Records from the FPS database and the Mortality Information System (SIM: a national database in Brazil) were linked through a probabilistic record linkage (RL). Mortality outcomes were defined based on ICD-10 (10th International Statistical Classification of Diseases and Related Health Problems) codes listed as the cause of death on the death certificate. Hazard ratios (HRs) were estimated for outcomes using Cox multiple regression models. RESULTS: When all causes of death were considered, RL identified 209 deaths (7.2%) among seropositive blood donors and 190 (3.3%) among seronegative blood donors. Donors seropositive for HCV infection had a 2.5 times higher risk of death due to all causes (95% CI: 1.76-2.62; p<0.001). When only liver-related causes of death were considered, RL identified 73 deaths among seropositive blood donors and only 6 among seronegative blood donors. Donors seropositive for HCV infection had a 23.4 times higher risk of death due to liver related causes (95% CI: 10.2-53.9; p<0.001). Donors seropositive for HCV had a 29.5 (95%CI: 3.9-221.7), 2.8 (95% CI: 1.4-5.5) and a 1.9 (95% CI: 1.2-3.0) times higher risk of death due to hepatocellular carcinoma, infection or trauma, respectively, compared to seronegative donors. CONCLUSIONS: All-cause and liver-related mortality rate was increased among blood donors seropositive for HCV compared with the mortality rate among seronegative blood donors. Our data confirms HCV as a relevant cause of death in Brazil and also suggest that interventions directed at following patients even after access to specific drug treatment are urgent and necessary.

The case for a universal hepatitis C vaccine to achieve hepatitis C elimination.

BACKGROUND: The introduction of highly effective direct-acting antiviral (DAA) therapy for hepatitis C has led to calls to eliminate it as a public health threat through treatment-as-prevention. Recent studies suggest it is possible to develop a vaccine to prevent hepatitis C. Using a mathematical model, we examined the potential impact of a hepatitis C vaccine on the feasibility and cost of achieving the global WHO elimination target of an 80% reduction in incidence by 2030 in the era of DAA treatment. METHODS: The model was calibrated to 167 countries and included two population groups (people who inject drugs (PWID) and the general community), features of the care cascade, and the coverage of health systems to deliver services. Projections were made for 2018-2030. RESULTS: The optimal incidence reduction strategy was to implement test and treat programmes among PWID, and in settings with high levels of community transmission undertake screening and treatment of the general population. With a vaccine available, the optimal strategy was to include vaccination within test and treat programmes, in addition to vaccinating adolescents in settings with high levels of community transmission. Of the 167 countries modelled, between 0 and 48 could achieve an 80% reduction in incidence without a vaccine. This increased to 15-113 countries if a 75% efficacious vaccine with a 10-year duration of protection were available. If a vaccination course cost US$200, vaccine use reduced the cost of elimination for 66 countries (40%) by an aggregate of US$7.4 (US$6.6-8.2) billion. For a US$50 per course vaccine, this increased to a US$9.8 (US$8.7-10.8) billion cost reduction across 78 countries (47%). CONCLUSIONS: These findings strongly support the case for hepatitis C vaccine development as an urgent public health need, to ensure hepatitis C elimination is achievable and at substantially reduced costs for a majority of countries.

Hepatitis B and C prevalence and risk factors among young men presenting to the Brazilian Army: A STROBE-compliant national survey-based cross-sectional observational study.

Viral hepatitis is caused by different etiological agents with distinct epidemiological, clinical, and laboratory characteristics accounting for significant worldwide morbidity and mortality. Since 1996, the Brazilian Department of Sexually Transmitted Infections (STIs), Acquired Immune Deficiency Syndrome (AIDS) and Viral Hepatitis (DIAHV) in collaboration with the Ministry of Defense has been conducting periodic serosurveys of conscripts enlisted for the Brazilian army to assess STI prevalence and obtain data on knowledge and risk factors pertaining to STIs. This article aims to present the hepatitis B (hepatitis B surface antigen - HBsAg) and C (anti-HCV) seroprevalence estimates and risk factors as per the 8th edition of the Conscript Survey performed in 2016.This cross-sectional study was conducted among conscripts across Brazil aged 17 to 22 years from August to December 2016. It included a self-reported questionnaire and blood testing for syphilis, human immunodeficiency virus (HIV), and hepatitis B and C.In total 38,247 conscripts were enrolled; after applying exclusion criteria, 37,282 conscripts were included. The estimated HBsAg and anti-HCV prevalence rates were 0.22% and 0.28%, respectively. Higher HBsAg and anti-HCV prevalence rates were observed in the North Region (0.49%) and in the Central-west Region (0.65%), respectively. Regarding hepatitis B vaccination, 23.5% (n = 8412) of the individuals reported being unvaccinated and 47.4% (n = 16,970) did not know if they had been vaccinated. Among the anti-HCV positive conscripts, 53% (n = 51, 0.56%, P = .049) reported that they had never had sexual intercourse. Regarding self-reported STI status, most of the positive anti-HCV (n = 100, 0.29%, P < .01) and positive HBsAg (n = 76, 0.22%, P = .205) conscripts reported not having a STI. From those who tested positive for HBsAg, 89% (n = 42, 0.28%, P = .005) reported not making consistent use of condoms with steady partners.Our data suggest a low prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among Brazilian young men, and relatively low rates of self-reported HBV immunization. History of STIs, higher number of partners, inconsistent use of condoms, and lack of awareness of routes of transmission were significantly associated with HBV and HCV infections. To achieve the World Health Organization's goal of viral hepatitis elimination, access to hepatitis information, testing, and surveillance need to be improved.

Decline in reported AIDS cases in Brazil after implementation of the test and treat initiative.

BACKGROUND: To evaluate the trends in AIDS detection and the AIDS-attributed death rate in Brazil between 2007 and 2015 and to determine the population characteristics associated with AIDS detection. METHODS: Surveillance data including demographics, mode of HIV transmission, AIDS cases, and AIDS-attributed deaths were analysed. A logistic regression model was fitted to assess the trends in AIDS cases by mode of HIV transmission throughout the study period. A segmented Poisson regression model was used to assess changes in the trends of AIDS detection and mortality rates before (2007-2014) and after (2015) the introduction of the Test and Treat Initiative. RESULTS: In the segmented Poisson regression, the decline in the AIDS detection rate from 2007 to 2014 was 2.0% annually (i.e., the odds ratio (OR) for annual decline was 0.98 (95% [CI: 0.98-1.00, p-value < 0.001). The observed AIDS detection rate in 2015 was 7.7 cases per 100,000, which was 60% lower than the regression estimate of 19.8 for the hypothetical absence of the Test and Treat Initiative. The reduction in AIDS-attributed deaths from 2007 to 2014 was 8.0% annually (i.e., the OR for annual decline was 0.92 (95% [CI: 0.91-0.95, p-value < 0.001). The observed AIDS mortality rate in 2015 was 0.49 cases per 100,000, which was 73% lower than the regression estimate of 2.1 for the hypothetical absence of the Test and Treat Initiative in 2015. CONCLUSIONS: Our results reveal a fairly stable AIDS detection rate from 2007 to 2014, with a sudden significant drop in 2015. This drop may be related to the increasing trends in rapid testing, the number of new HIV diagnoses, the number of patients on antiretroviral therapy (ART), and a median CD4 count at ART enrolment. Further evaluation of the effects of the Test and Treat Initiative on AIDS diagnosis and mortality is needed and must be strengthened with additional data from subsequent years.

Factors associated with HPV and other self-reported STI coinfections among sexually active Brazilian young adults: cross-sectional nationwide study.

OBJECTIVES: To analyse factors associated with genital human papillomavirus (HPV) and other self-reported sexually transmitted infection (STI) coinfections among women and men aged 16-25 years from Brazil. DESIGN: A cross-sectional, nationwide, multicentre study. SETTING: 119 primary healthcare centres between September 2016 and November 2017. PARTICIPANTS: 6388 sexually active young adults were enrolled by trained health professionals. PRIMARY OUTCOME MEASURE: Genital HPV and other self-reported STI coinfections. RESULTS: Of 3512 participants with valid data for genital HPV and (STI)-positive status, 276 (9.60%, 95% CI 7.82% to 11.36%) had HPV/STI coinfection. Among men, HPV/STI coinfection was more prevalent than HPV infection alone. Among HPV-positive participants, the percentage of subjects who reported having another STI was highest for gonorrhoea at 4.24% (95% CI 2.67% to 5.81%), followed by syphilis, herpes and HIV. Smoking, drug use and ever having a same-sex sexual experience were risk factors that were uniquely associated with HPV/STI coinfection compared with HPV infection alone. CONCLUSIONS: The results identified a low prevalence of self-reported STIs, but in participants with at least one STI, the prevalence of HPV was high. These results reinforce the importance of implementing strategies to prevent risky behaviours among Brazilian young adults.
