[Association between schooling and mortality rate from dengue in Brazil]. / Associação entre escolaridade e taxa de mortalidade por dengue no Brasil.

Dengue may be associated with individual level variables, such as schooling, increasing the risk of illness. The objective of this study is to analyze the disparities in dengue mortality among the least and the most educated in Brazil, from 2010 to 2018. This is a retrospective ecological study of the differences in the mortality rate due to dengue between the less and the more educated people in Brazil, according to the mortality rates due to general dengue, by age, sex, and Federative Unit (UF). A bootstrap and multiple imputation procedure for the variable schooling was implemented to consider the multilevel structure of the data from each UF over the years. For each aggregate bank generated, a multilevel Poisson model was adjusted. The improvement in the education level of the Brazilian population did not reflect on the decrease in mortality from dengue. There was an increase in the mortality rate from dengue in Brazil and an increase in the difference in mortality rates between less and more educated. Regardless of the imputation process, the results showed higher mortality rates from dengue among the less educated. Low schooling affected younger people more pronouncedly.

Same-day initiation of oral pre-exposure prophylaxis among gay, bisexual, and other cisgender men who have sex with men and transgender women in Brazil, Mexico, and Peru (ImPrEP): a prospective, single-arm, open-label, multicentre implementation study.

BACKGROUND: Although gay, bisexual, and other cisgender men who have sex with men (MSM) and transgender women have the highest HIV burden in Latin America, pre-exposure prophylaxis (PrEP) implementation is poor. We aimed to assess the feasibility of same-day oral PrEP delivery in Brazil, Mexico, and Peru. METHODS: Implementation PrEP (ImPrEP) was a prospective, single-arm, open-label, multicentre PrEP implementation study conducted in Brazil (14 sites), Mexico (four sites), and Peru (ten sites). MSM and transgender women were eligible to participate if they were aged 18 years or older, HIV-negative, and reported one or more prespecified criteria. Enrolled participants received same-day initiation of daily oral PrEP (tenofovir disoproxil fumarate [300 mg] coformulated with emtricitabine [200 mg]). Follow-up visits were scheduled at week 4 and quarterly thereafter. We used logistic regression models to identify factors associated with early loss to follow-up (not returning after enrolment), PrEP adherence (medication possession ratio ≥0·6), and long-term PrEP engagement (attending three or more visits within 52 weeks). This study is registered at the Brazilian Registry of Clinical Trials, U1111-1217-6021. FINDINGS: From Feb 6, 2018, to June 30, 2021, 9979 participants were screened and 9509 were enrolled (Brazil n=3928, Mexico n=3288, and Peru n=2293). 543 (5·7%) participants were transgender women, 8966 (94·3%) were cisgender men, and 2481 (26·1%) were aged 18-24 years. There were 12 185·25 person-years of follow-up. 795 (8·4%) of 9509 participants had early loss to follow-up, 6477 (68·1%) of 9509 were adherent to PrEP, and 5783 (70·3%) of 8225 had long-term PrEP engagement. Transgender women (adjusted odds ratio 1·60, 95% CI 1·20-2·14), participants aged 18-24 years (1·80, 1·49-2·18), and participants with primary education (2·18, 1·29-3·68) had increased odds of early loss to follow-up. Transgender women (0·56, 0·46-0·70), participants aged 18-24 years (0·52, 0·46-0·58), and those with primary education (0·60, 0·40-0·91) had lower odds of PrEP adherence. Transgender women (0·56, 0·45-0·71), participants aged 18-24 years (0·56, 0·49-0·64), and those with secondary education (0·74, 0·68-0·86) had lower odds of long-term PrEP engagement. HIV incidence was 0·85 per 100 person-years (95% CI 0·70-1·03) and was higher for transgender women, participants from Peru, those aged 18-24 years, Black and mixed-race participants, and participants who were non-adherent to PrEP. INTERPRETATION: Same-day oral PrEP is feasible for MSM and transgender women in Latin America. Social and structural determinants of HIV vulnerability need to be addressed to fully achieve the benefits of PrEP. FUNDING: Unitaid, WHO, and Ministries of Health in Brazil, Mexico, and Peru.

Travestis, transgender women and young MSM are at high risk for PrEP early loss to follow-up in Rio de Janeiro, Brazil.

INTRODUCTION: Oral pre-exposure prophylaxis (PrEP) with emtricitabine/tenofovir (FTC/TDF) is highly effective in preventing HIV infection. This study aimed to identify factors associated with PrEP early loss to follow-up (ELFU) among gay, bisexual and other men who have sex with men (MSM), travestis and transgender women (TGW). METHODOLOGY: This was a prospective cohort study evaluating TGW and MSM who initiated PrEP at the Evandro Chagas National Institute of Infectious Diseases (INI-Fiocruz) from 2014 to 2020. ELFU was defined as not returning for a PrEP visit within 180 days after first dispensation. Exposure variables included age, gender, race, education, transactional sex, condomless anal intercourse [CAI] (both in the past six months), binge drinking and substance use (both in past three months) and syphilis diagnosis at baseline. Multilevel logistic regression models with random intercepts and fixed slopes were used to identify factors associated with ELFU accounting for clustering of participants according to their PrEP initiation study/context (PrEP Brasil, PrEParadas, ImPrEP and PrEP SUS). RESULTS: Among 1,463 participants, the median age was 29 years (interquartile range 24-36), 83% self-identified as MSM, 17% as TGW, 24% were black, 37% mixed-black/pardo and 30% had < 12 years of education. Fifteen percent reported transactional sex, 59% reported CAI, 67% binge drinking, 33% substance use, and 15% had a syphilis diagnosis. Overall, 137 participants (9.7%) had ELFU. Younger age (18-24 years) (adjusted odds ratio [aOR] 1.9, 95%CI:1.2-3.2), TGW (aOR 2.8, 95%CI:1.6-4.8) and education < 12 years (aOR 1.9, 95%CI:1.2-2.9) were associated with greater odds of ELFU. CONCLUSION: TGW, young individuals and those with lower education were at higher risk of PrEP ELFU. Our results suggest that the development of specific strategies targeting these populations should be a priority, through policies that aim to reduce the incidence of HIV infection.

Factors associated with long-term HIV pre-exposure prophylaxis engagement and adherence among transgender women in Brazil, Mexico and Peru: results from the ImPrEP study.

INTRODUCTION: The HIV epidemic continues to disproportionately impact Latin-American transgender women (TGW). We assessed factors associated with long-term pre-exposure prophylaxis (PrEP) engagement and adherence among TGW enrolled in the Implementation of PrEP (ImPrEP) study, the largest PrEP demonstration study in Latin America. METHODS: HIV-negative TGW aged ≥18 years reporting 1+eligibility criteria in the 6 months prior to enrolment (e.g. sex partner known to be living with HIV, condomless anal sex [CAS], transactional sex or having a sexually transmitted infection [STI]) who could safely take PrEP were enrolled. Follow-up visits were conducted at 4 weeks and then quarterly. We conducted logistic regression to identify factors associated with long-term PrEP engagement (3+ follow-up visits in 52 weeks) and complete self-reported adherence (no missed pills in the past 30 days) during follow-up. For both outcomes, we constructed multivariable models controlling for country, socio-demographics, sexual behaviour, substance use, STIs and self-reported adherence at 4 weeks (long-term engagement outcome only). RESULTS: From March 2018 to June 2021, ImPrEP screened 519 TGW, enrolled 494 (Brazil: 190, Mexico: 66 and Peru: 238) and followed them for 52 weeks. At baseline, 27.5% of TGW were aged 18-24 years, 67.8% were mixed-race and 31.6% had >secondary education. Most, 89.9% reported CAS, 61.9% had >10 sex partners and 71.9% reported transactional sex. HIV incidence was 1.82 cases per 100 person-years (95% confidence interval [CI]: 0.76-4.38). Almost half of TGW (48.6%) had long-term PrEP engagement, which was positively associated with reporting complete adherence at week 4 (aOR:2.94 [95%CI:1.88-4.63]) and was inversely associated with reporting CAS with unknown-HIV partner (aOR:0.52 [95%CI:0.34-0.81]), migration (aOR:0.54 [95%CI:0.34-0.84]), and being from Mexico (aOR:0.28 [95%CI:0.14-0.53]). Self-reported adherence was associated with TGW aged >34 (aOR:1.61 [95%CI:1.10-2.34]) compared to those aged 25-34 and those with >secondary education (aOR:1.55 [95%CI:1.10-2.19]) and was lower among TGW from Peru (aOR:0.29 [95%CI:0.21-0.41]) or reporting PrEP-related adverse effects (aOR:0.63 [95%CI:0.42-0.92]). CONCLUSIONS: Although TGW were willing to enrol in ImPrEP, long-term PrEP engagement and complete self-reported adherence were limited, and HIV incidence remained relatively high. A successful HIV prevention agenda should include trans-specific interventions supporting oral PrEP and exploring long-acting PrEP strategies for TGW.

[Changes in the pattern of COVID-19 hospitalizations and deaths after substantial vaccination of the elderly in Manaus, Amazonas State, Brazil]. / Mudanças no padrão de internações e óbitos por COVID-19 após substancial vacinação de idosos em Manaus, Amazonas, Brasil.

The impact of COVID-19 vaccination in the elderly has received relatively little attention, particularly in a scenario predominated by the gamma variant. The aim of this study was to assess vaccination coverage and its relationship to changes in the pattern of COVID-19 hospitalizations and deaths in the elderly in Manaus, Amazonas State, Brazil. This was an ecological study with Brazilian Ministry of Health data on hospitalizations and deaths, assessing vaccination coverage based on a two-dose regimen, in addition to two vaccination regimens associated with a significant protective effect, one partial (35 days or more after the first dose of the Oxford/AstraZeneca vaccine) and the other complete (14 days or more after the second dose of the Sinovac-CoronaVac vaccine). Based on the date of initial symptoms, patterns of COVID-19 hospitalizations and deaths were assessed comparatively in elderly 60-69 years and 70 years or more in two groups of Epidemiological Weeks (EW) in 2020 (unvaccinated) and 2021 (vaccinated). Hospitalization and death rates were estimated with Poisson regression. In the groups 60-69 and 70 years or more, vaccination coverage rates were 41.8% and 54.8%, as well as 53.5% and 90.1%, in the EW groups 18-20/2021 and 21-23/2021, respectively. Both EW groups in 2021 showed a substantial change in the patterns of COVID-19 hospitalizations and deaths, with an increase in the risk of hospitalization and death in unvaccinated younger individuals and an important reduction in vaccinated elderly, especially those 60-69 years of age, besides overall reductions of 62% (95%CI: 52-69) and 63% (95%CI: 43-75) in hospitalization and death rates, respectively. Our results emphasize the importance of mass vaccination, especially during an epidemic such as in Manaus, marked by high circulation of the gamma variant.

A avaliação do impacto da vacinação contra a COVID-19 em idosos é escassa, sobretudo em um cenário com predomínio da variante Gama. O objetivo deste estudo foi avaliar a cobertura vacinal e sua relação com mudanças no padrão de internações e óbitos por COVID-19 em idosos de Manaus, Amazonas, Brasil. Este é um estudo ecológico com dados de internações e óbitos do Ministério da Saúde que avaliou a cobertura vacinal, mediante esquema com duas doses, além de dois regimes de vacinação associados a significativo efeito protetor, um parcial (35 ou mais dias após a primeira dose da vacina Oxford/AstraZeneca) e outro completo (14 dias ou mais após a segunda dose da vacina Sinovac-CoronaVac). A partir da data dos primeiros sintomas, padrões de internação e óbito por COVID-19 foram avaliados, comparativamente, em idosos de 60-69 e de 70 anos ou mais, em dois grupos de Semanas Epidemiológicas (SE) de 2020 (não vacinados) e 2021 (vacinados). Taxas de internação e óbito foram estimadas pelo modelo Poisson. Entre 60-69 anos e naqueles com 70 anos ou mais, a cobertura por vacina foi 41,8% e 54,8%, bem como 53,5% e 90,1% nos grupos de SE 18-20/2021 e 21-23/2021, respectivamente. Em ambos os grupos de SE de 2021, observou-se substancial mudança nos padrões de internações e óbitos por COVID-19, com aumento no risco de internação e óbito nos mais jovens não vacinados, e importante redução no número de idosos vacinados, sobretudo naqueles com 60-69 anos, além de redução global de 62% (IC95%: 52-69) e 63% (IC95%: 43-75) nas taxas de internação e óbitos, respectivamente. Nossos resultados reforçam a importância da vacinação em massa, especialmente em contexto epidêmico como o de Manaus, marcado por elevada circulação da variante Gama.

El objetivo de este estudio fue evaluar la cobertura de vacunación y su relación con cambios en el patrón de internamientos y óbitos por COVID-19 en ancianos de Manaos, Amazonas, Brasil. Este es un estudio ecológico con datos de internamientos y óbitos del Ministerio de Salud, que evaluó la cobertura de vacunación, mediante un esquema con dos dosis, además de dos regímenes de vacunación, asociados a un significativo efecto protector, uno parcial (35 o más días tras la primera dosis de la vacuna Oxford/AstraZeneca) y otro completo (14 días o más tras la segunda dosis de la vacuna Sinovac-CoronaVac). A partir de los datos de los primeros síntomas, se evaluaron patrones de internamiento y óbito por COVID-19, comparativamente, en ancianos de 60-69 y de 70 años o más, en dos grupos de Semanas Epidemiológicas (SE) de 2020 (no vacunados) y 2021 (vacunados). Se estimaron tasas de internamiento y óbito mediante el modelo Poisson. Entre 60-69 años y en aquellos con 70 años o más, la cobertura por vacuna fue 41,8% y 54,8%, así como 53,5% y 90,1% en los grupos de SE 18-20/2021 y 21-23/2021, respectivamente. En ambos grupos de SE de 2021, se observó un cambio sustancial en los patrones de internamiento y óbitos por COVID-19, con un aumento en el riesgo de internamiento y óbito en los más jóvenes no vacunados e importante reducción en los ancianos vacunados, sobre todo en aquellos con 60-69 años, además de una reducción global de 62% (IC95%: 52-69) y 63% (IC95%: 43-75) en las tasas de internamiento y óbitos, respectivamente. Nuestros resultados refuerzan la importancia de la vacunación en masa, especialmente en un contexto epidémico como el de Manaos, marcado por una elevada circulación de la variante Gamma.

Low PrEP adherence despite high retention among transgender women in Brazil: the PrEParadas study.

INTRODUCTION: We aimed to evaluate daily oral pre-exposure prophylaxis (PrEP) uptake, retention, and adherence and predictors of study non-attendance and low PrEP adherence in a Brazilian trans-specific 48-week study (PrEParadas). METHODS: We enrolled transgender women (TGW) engaging in high-risk sexual behaviours between August 2017 and December 2018. PrEP adherence was based on tenofovir diphosphate concentrations in dried blood spots (DBS). We used random effects logistic regression models and ordinal models to estimate the odds of having a missed visit and of low PrEP adherence, respectively. Multivariable models were adjusted for variables with p-value<0.10 in the univariate analysis. RESULTS: From the 271 eligible, 130 participants were enrolled in the study (PrEP uptake: 48%), out of which 111 (85.4%) were retained at 48 weeks. Multivariable model for study non-attendance included study visit, age, main sexual partner and stimulant use. The odds of missing a visit increased after the week 24. Participants aged 18-24 (adjusted odds ratio [aOR] = 8.76, 95% CI: 2.09-36.7) and 25-34 years (aOR = 6.79, 95% CI: 1.72-26.8) compared to TGW aged 35+ years had significantly higher odds of having a missed visit. The odds of a missed visit were higher among participants reporting stimulant use (aOR = 4.99, 95% CI: 1.37-18.1) compared to no stimulant use. DBS levels at week 48 showed that 42 (38.5%), 14 (12.8%) and 53 (48.6%) of 109 participants had low, moderate and high PrEP adherence. Multivariable model for low PrEP adherence included study visit, age, schooling, race/colour, housing, binge drinking, stimulant use, feminizing hormone therapy (FHT) use and received text message. Low PrEP adherence was significantly higher among participants with less years of schooling (aOR = 6.71, 95% CI: 1.30-34.5) and had a borderline association with Black colour/race (aOR = 6.72, 95% CI: 0.94-47.8). Participants using the FHT available at the site had decreased odds of low PrEP adherence (aOR = 0.38, 95% CI: 0.16-0.88). No participant seroconverted over the course of the study. CONCLUSIONS: Although high PrEP retention can be achieved in a gender-affirming setting, PrEP adherence may be an important challenge faced among TGW due to social disparities. The scale-up of prevention tools like PrEP will have to address systemic social determinants as these stand as important barriers for TGW's access to health services.

Kidney function and daily emtricitabine/tenofovir disoproxil fumarate pre-exposure prophylaxis against HIV: results from the real-life multicentric demonstrative project PrEP Brazil.

BACKGROUND: Pre-Exposure Prophylaxis (PrEP) has demonstrated efficacy in the reduction of sexually transmitted HIV infections. The prolonged use of tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC) co-formulation (TDF/FTC), however, may result in augmented risk of renal toxicity. We aimed to evaluate changes in the estimated Glomerular Filtration Rate (eGFR) in a real-world population setting of participants enrolled in PrEP Brazil, a 48-week prospective, open-label, demonstration study to assess the feasibility of daily oral TDF/FTC used by men who have sex with men and transgender women at high-risk of HIV infection, all over 18 years old. METHODS: Kidney function was assessed by serial measurement of serum creatinine and eGFR with the Modification of Diet in Renal Disease Study (MDRD) formula on weeks 4, 12, 24, 36 and 48. Adherence to PrEP was assessed by dosing TDF concentration in dried blood spots at weeks 4 and 48, measured by liquid chromatography-mass spectrometry or mass spectrometry. RESULTS: Of 392 participants completing the 48-week follow-up protocol with TDF blood detectable levels and eGFR measures, 43.1% were young adults, of Caucasian ethnic background (57.9%), with BMI below 30 kg/m2, without arterial hypertension. At screening, median eGFR was 93.0 mL/min/1.73 m2. At week 4 follow-up, 90 (23% of the study population) participants presented reductions in eGFR greater than 10 mL/min/1.73 m2 as compared to baseline eGFR, some as large as 59 mL/min/1.73 m2, but with no clinical outcomes (adverse events and renal adverse events) severe enough to demand TDF/FTC discontinuation. A negative relationship was observed between TDF blood levels and eGFR at weeks 4 (r = - 0.005; p < 0.01) and 48 (r = - 0.006; p < 0.01). CONCLUSIONS: These results suggest that the renal function profile in individuals on TDF/FTC may be assessed on week 4 and then only annually, allowing a more flexible medical follow-up in primary care centers.

This was an ecological study with Brazilian Ministry of Health data on hospitalizations and deaths, assessing vaccination coverage based on a two-dose regimen, in addition to two vaccination regimens associated with a significant protective effect, one partial (35 days or more after the first dose of the Oxford/AstraZeneca vaccine) and the other complete (14 days or more after the second dose of the Sinovac-CoronaVac vaccine). Based on the date of initial symptoms, patterns of COVID-19 hospitalizations and deaths were assessed comparatively in elderly 60-69 years and 70 years or more in two groups of Epidemiological Weeks (EW) in 2020 (unvaccinated) and 2021 (vaccinated). Hospitalization and death rates were estimated with Poisson regression. In the groups 60-69 and 70 years or more, vaccination coverage rates were 41.8% and 54.8%, as well as 53.5% and 90.1%, in the EW groups 18-20/2021 and 21-23/2021, respectively. Both EW groups in 2021 showed a substantial change in the patterns of COVID-19 hospitalizations and deaths, with an increase in the risk of hospitalization and death in unvaccinated younger individuals and an important reduction in vaccinated elderly, especially those 60-69 years of age, besides overall reductions of 62% (95%CI: 52-69) and 63% (95%CI: 43-75) in hospitalization and death rates, respectively. Our results emphasize the importance of mass vaccination, especially during an epidemic such as in Manaus, marked by high circulation of the gamma variant.

La evaluación del impacto de la vacunación contra la COVID-19 en ancianos es escasa, sobre todo en un escenario con predominio de la variante Gamma. El objetivo de este estudio fue evaluar la cobertura de vacunación y su relación con cambios en el patrón de internamientos y óbitos por COVID-19 en ancianos de Manaos, Amazonas, Brasil. Este es un estudio ecológico con datos de internamientos y óbitos del Ministerio de Salud, que evaluó la cobertura de vacunación, mediante un esquema con dos dosis, además de dos regímenes de vacunación, asociados a un significativo efecto protector, uno parcial (35 o más días tras la primera dosis de la vacuna Oxford/AstraZeneca) y otro completo (14 días o más tras la segunda dosis de la vacuna Sinovac-CoronaVac). A partir de los datos de los primeros síntomas, se evaluaron patrones de internamiento y óbito por COVID-19, comparativamente, en ancianos de 60-69 y de 70 años o más, en dos grupos de Semanas Epidemiológicas (SE) de 2020 (no vacunados) y 2021 (vacunados). Se estimaron tasas de internamiento y óbito mediante el modelo Poisson. Entre 60-69 años y en aquellos con 70 años o más, la cobertura por vacuna fue 41,8% y 54,8%, así como 53,5% y 90,1% en los grupos de SE 18-20/2021 y 21-23/2021, respectivamente. En ambos grupos de SE de 2021, se observó un cambio sustancial en los patrones de internamiento y óbitos por COVID-19, con un aumento en el riesgo de internamiento y óbito en los más jóvenes no vacunados e importante reducción en los ancianos vacunados, sobre todo en aquellos con 60-69 años, además de una reducción global de 62% (IC95%: 52-69) y 63% (IC95%: 43-75) en las tasas de internamiento y óbitos, respectivamente. Nuestros resultados refuerzan la importancia de la vacunación en masa, especialmente en un contexto epidémico como el de Manaos, marcado por una elevada circulación de la variante Gamma.

Factors associated with self-reported adherence to daily oral pre-exposure prophylaxis among men who have sex with man and transgender women: PrEP Brasil study.

Understanding the factors associated with pre-exposure prophylaxis (PrEP) adherence may help in the development of strategies to support, motivate and sustain PrEP use. This study estimated self-reported adherence, described perceived barriers and facilitators and investigated factors associated with adherence to daily oral PrEP among men who have sex with man (MSM) and transgender women after 1 year of PrEP use in Brazil. PrEP Brasil was a prospective, multicentre, open-label demonstration study with MSM and transgender women at high risk for HIV infection. We used logistic regression to evaluate factors associated with complete adherence (not forgetting to take any pills in the past 30 days) at week 48. Of 338 participants included in this analysis, 60% reported complete adherence to daily oral PrEP at week 48. Perceived barriers and facilitators to daily oral PrEP were reported by 38.2% and 98.5%, respectively. The most reported barrier and facilitator were 'I forgot to take my pills' (19.2%) and 'Associate PrEP with a daily activity/task' (58.6%), respectively. In final multivariable analysis, living in Rio de Janeiro (aOR: 0.38; 95% CI: 0.20-0.73), being transgender women (aOR: 0.22; 95% CI: 0.07-0.73), reporting stimulant use (a OR: 0.40; 95% CI: 0.20-0.80) and having any perceived barriers to daily oral PrEP (aOR: 0.12; 95% CI: 0.07-0.23) were associated with decreased odds of complete adherence. Our findings provide information for developing the best practices to promote PrEP adherence in the Brazilian context.

[Excess deaths during the COVID-19 pandemic: underreporting and regional inequalities in Brazil]. / Excesso de mortes durante a pandemia de COVID-19: subnotificação e desigualdades regionais no Brasil.

Brazil is one of the most heavily impacted countries by the COVID-19 pandemic, and the real number of deaths from the disease makes the scenario even more challenging. This study aimed to estimate the excess deaths and their differences in adults 20 years and older in Manaus (Amazonas State), Fortaleza (Ceará State), Rio de Janeiro, and São Paulo, according to place of death, demographic characteristics, and trajectory over time. The data were obtained from the Mortality Information System and the Central Information Office of the National Civil Registry. The estimates of expected deaths were obtained from quasi-Poisson generalized additive models, adjusting for overdispersion. From February 23 to June 13, 2020, 74,410 natural deaths were recorded in the four cities, with 46% excess deaths (95%CI: 44-47). The largest amount of excess deaths was in Manaus, with 112% (95%CI: 103-121), followed by Fortaleza with 72% (95%CI: 67-78), Rio de Janeiro with 42% (95%CI: 40-45), and São Paulo with 34% (95%CI: 32-36). Excess deaths were greater in males and non-significant in Epidemiologic Weeks (EW) 9-12, except in São Paulo, 10% (95%CI: 6-14). The peak in excess deaths generally occurred in EW 17-20. The number of excess deaths not explained directly by COVID-19 and deaths at home or on public byways is high, especially in Manaus. The high percentages of excess deaths, deaths not explained directly by COVID-19, and deaths outside the hospital suggest high underreporting of deaths from COVID-19 and reinforce the extensive spread of SARS-CoV-2, as well as the need for epidemiological surveillance services to review all causes of deaths associated with respiratory symptoms.

O objetivo deste estudo foi estimar o excesso de mortes e suas diferenças em adultos com 20 anos e mais em Manaus (Amazonas), Fortaleza (Ceará), Rio de Janeiro e São Paulo, de acordo com o local de ocorrência do óbito, características demográficas e trajetória ao longo do tempo. Os dados foram obtidos no Sistema de Informações sobre Mortalidade e na Central de Informações do Registro Civil Nacional. As estimativas de óbitos esperados foram obtidas por meio de modelos aditivos generalizados quasi-Poisson com ajuste de sobredispersão. Entre 23 de fevereiro e 13 de junho de 2020, foram registradas 74.410 mortes naturais nas quatro cidades, com excesso de mortes de 46% (IC95%: 44-47). O maior excesso de mortes ocorreu em Manaus, 112% (IC95%: 103-121), seguido por Fortaleza, 72% (IC95%: 67-78), Rio de Janeiro, 42% (IC95%: 40-45) e São Paulo, 34% (IC95%: 32-36). O excesso de mortes foi maior nos homens e não significativo nas Semanas Epidemiológicas (SE) 9-12, exceto em São Paulo, 10% (IC95%: 6-14). Em geral, o pico de mortes excedentes ocorreu nas SE 17-20. O excesso de mortes não explicado diretamente pela COVID-19 e de mortes em domicílios/via pública foi alto, especialmente em Manaus. A elevada porcentagem de mortes excedentes, de mortes não explicadas diretamente pela COVID-19 e de mortes fora do hospital sugerem alta subnotificação de mortes por COVID-19 e reforça a extensa dispersão do SARS-CoV-2, como também a necessidade da revisão de todas as causas de mortes associadas a sintomas respiratórios pelos serviços de vigilância epidemiológica.

El exceso de muertes no explicado directamente por la COVID-19 y de las muertes en domicilios/vía pública fue alto, especialmente en Manaus. El elevado porcentaje de muertes excedentarias, de muertes no explicadas directamente por la COVID-19, y de muertes fuera del hospital, sugieren una alta subnotificación de muertes por COVID-19 y refuerza la extensa dispersión del SARS-CoV-2, así como también la necesidad de una revisión de todas las causas de muertes asociadas a síntomas respiratorios, por parte de los servicios de vigilancia epidemiológica.

Explosion in mortality in the Amazonian epicenter of the COVID-19 epidemic 19. / Explosão da mortalidade no epicentro amazônico da epidemia de COVID-19.

Manaus, the capital of the Brazilian State of Amazonas, is the current epicenter of the COVID-19 epidemic in Amazonia. The sharp increase in deaths is a huge concern for health system administrators and society. The study aimed to analyze excess overall mortality according to Epidemiological Week (EW) in order to identify changes potentially associated with the epidemic in Manaus. Overall and cause-specific mortality data were obtained from the Central Database of the National Civil Registry and the Mortality Information System for 2018, 2019, and 2020. The study analyzed age bracket, sex, place of death, EW, calendar year, and causes of death. Ratios were calculated between deaths in 2019/2018 and 2020/2019 to estimate excess deaths, with 5% confidence intervals. No significant excess overall mortality was seen in the ratios for 2019/2018, independently of EW. Meanwhile, the ratios for 2020/2019 increased from 1.0 (95%CI: 0.9-1.3) in EW 11 to 4.6 (95%CI: 3.9-5.3) in EW 17. Excess overall mortality was observed with increasing age, especially in individuals 60 years or older, who accounted for 69.1% (95%CI: 66.8-71.4) of the deaths. The ratios for 2020/2019 for deaths at home or on public byways were 1.1 (95%CI: 0.7-1.8) in EW 12 and 7.8 (95%CI: 5.4-11.2) in EW 17. The explosion in overall mortality in Manaus and the high proportion of deaths at home or on public byways reveals the epidemic's severity in contexts of heavy social inequality and weak effectiveness of government policies, especially policies meant to deal with social inequalities and strengthen the Unified Health System.

Explosão da mortalidade no epicentro amazônico da epidemia de COVID-19 / Explosión de la mortalidad en el epicentro amazónico de la epidemia de COVID-19 / Explosion in mortality in the Amazonian epicenter of the COVID-19 epidemic 19

Manaus, capital do estado brasileiro do Amazonas, é o atual epicentro da epidemia na Amazônia com um aumento repentino de mortes que preocupa gestores e sociedade. O objetivo do estudo foi analisar o excesso na mortalidade geral, segundo Semanas Epidemiológicas (SE), visando a identificar mudanças potencialmente associadas à epidemia em Manaus. Dados de mortalidade geral e grupos de causas foram obtidos na Central de Informações do Registro Civil Nacional e no Sistema de Informações sobre Mortalidade, para 2018, 2019 e 2020. Analisou-se faixa etária, sexo, local de ocorrência do óbito, SE, ano-calendário e causas de morte. Calcularam-se razões entre as mortes ocorridas em 2019/2018 e 2020/2019 para avaliar o excesso de mortes, com intervalos de confiança no nível de 5%. Não observou-se excesso de mortalidade geral significativo nas razões 2019/2018, independentemente da SE. Já as razões de 2020/2019 passaram de 1,0 (IC95%: 0,9-1,3) na SE 12 para 4,6 (IC95%: 3,9-5,3) na SE 17. Observou-se excesso de mortalidade geral com a progressão da idade, especialmente em indivíduos com 60 anos e mais, os quais concentraram 69,1% (IC95%: 66,8-71,4) das mortes. A razão 2020/2019 para óbitos em domicílio/via pública foi de 1,1 (IC95%: 0,7-1,8) na SE 12 e de 7,8 (IC95%: 5,4-11,2) na SE 17. A explosão da mortalidade geral em Manaus e a elevada proporção de óbitos em domicílio/via pública expõe a gravidade da epidemia em contextos de grande desigualdade social e fraca efetividade de ações governamentais, em especial aquelas voltadas ao enfrentamento das desigualdades sociais e para a garantia e fortalecimento do Sistema Único de Saúde.

Manaus, capital del estado brasileño del Amazonas, es el actual epicentro de la epidemia en Amazonia y el aumento repentino de muertes preocupa a gestores y a la sociedad. El objetivo del estudio fue analizar el exceso en la mortalidad general, según Semanas Epidemiológicas (SE), con el objetivo de identificar cambios potencialmente asociados a la epidemia en Manaus. Los datos de mortalidad general y grupos de causas se obtuvieron en la Central de Información del Registro Civil Nacional y en el Sistema de Información sobre Mortalidad, referentes a 2018, 2019 y 2020. Se analizó franja de edad, sexo, lugar donde se produjo el fallecimiento, SE, año-calendario y causas de muerte. Se calcularon las causas entre las muertes acaecidas en 2019/2018 y 2020/2019 para evaluar el exceso de muertes, con intervalos de confianza en el nivel de 5%. No se observó un exceso de mortalidad general significativo en las causas 2019/2018, independientemente de la SE. Ya las causas de 2020/2019 pasaron de 1,0 (IC95%: 0,9-1,3) en la SE 12 a 4,6 (IC95%: 3,9-5,3) en la SE 17. Se observó un exceso de mortalidad general con la progresión de la edad, especialmente en individuos con 60 años y más, quienes concentraron un 69,1% (IC95%: 66,8-71,4) de las muertes. La razón 2020/2019 para óbitos en domicilio/vía pública fue de 1,1 (IC95%: 0,7-1,8) en la SE 12 y de 7,8 (IC95%: 5,4-11,2) en la SE 17. La explosión de la mortalidad general en Manaus y la elevada proporción de óbitos en domicilio/vía pública expone la gravedad de la epidemia en contextos de gran desigualdad social y débil efectividad de las acciones gubernamentales, en especial aquellas dirigidas al combate de las desigualdades sociales y para la garantía y fortalecimiento del Sistema Único de Salud.

Urban violence and risk factors for femicide in the Brazilian Amazon. / Violência urbana e fatores de risco relacionados ao feminicídio em contexto amazônico brasileiro.

Femicide has received relatively little research attention, despite its severity. Estimates of femicide depend on the strategies used to define it within the sociocultural and political context. This study aimed to assess intentional homicides of women, focusing on femicides, highlighting the characteristics and risk factors. This was a cross-sectional study based on daily surveillance of homicides in the press and mortality records. The study considered fatal victims of assault in women over 11 years of age in Manaus, Amazonas State, Brazil, in 2016-2017. Classification of femicide was based on Brazil's Law n. 13,104/2015. Relative risk was estimated by Poisson regression, and a hierarchical model was used to include variables in the models. Analyses were performed in the R statistical package. Of 138 fatal victims of assault, 52 were cases of femicide, or 37.7% (CI: 29.4-45.5). Each unit addition of age reduced the risk of femicide by 3% (CI: 0.95-0.99). Risk of femicide was 40% lower (CI: 0.40-0.90) in women with up to seven years of schooling, when compared to those with eight years or more. Women killed by bodily force showed 5.5 times higher risk (CI: 2.6-11.3) of femicide, compared to those killed with firearms. Relative risk of femicide was 1.4 (CI: 1.1-2.7) in women killed in daytime, compared to those killed at night. The proportion of femicide in this study was lower than in previous estimates in Brazil, and the local burden of urban crime appears to explain part of this discrepancy. This study showed that age, schooling, use of bodily force, and time of day when the assault occurred are associated with femicide.

Apesar de sua gravidade, o feminicídio é pouco investigado e suas estimativas dependem das estratégias usadas à sua caracterização, do contexto sociocultural e político. Este estudo teve como objetivo avaliar os homicídios intencionais de mulheres, com enfoque nos feminicídios, destacando suas características e fatores de risco. Estudo transversal, baseado em vigilância diária de homicídios na imprensa e em registros de mortalidade. Foram consideradas vítimas fatais por agressões, mortes de mulheres maiores de 11 anos, residentes em Manaus, Amazonas, Brasil, em 2016-2017. A classificação de feminicídios baseou-se na Lei nº 13.104/2015. O risco relativo foi estimado mediante regressão de Poisson e um modelo hierárquico foi empregado para a introdução das variáveis nos modelos. As análises foram efetuadas no software R. De 138 vítimas fatais por agressões, 52 foram feminicídios, 37,7% (IC: 29,4-45,5). A cada acréscimo unitário de idade o risco de feminicídio reduzia em 3% (IC: 0,95-0,99). O risco de feminicídio foi 40% menor (IC: 0,40-0,90) nas mulheres com até sete anos de escolaridade, em comparação às que tinham oito anos ou mais; as mulheres agredidas mediante força corporal tiveram risco 5,5 (IC: 2,6-11,3) vezes maior de feminicídio, em comparação às que foram agredidas com arma de fogo; e risco de feminicídio de 1,4 (IC: 1,1-2,7) nas que foram mortas durante o dia, em relação às que morreram de noite. A proporção de feminicídio deste estudo foi inferior a estimativas prévias no Brasil e a carga local da criminalidade urbana parece explicar parte desta divergência. Este trabalho demonstrou que idade, escolaridade, uso da força corporal e turno da agressão estão associados ao feminicídio.

El objetivo de este estudio fue evaluar los homicidios intencionales de mujeres, centrándose en los feminicidios, destacando sus características y factores de riesgo. Se trata de un estudio transversal, basado en la vigilancia diaria de homicidios en prensa y en registros de mortalidad. Se consideraron víctimas fatales por agresiones, muertes de mujeres mayores de 11 años, residentes en Manaus, Amazonas, Brasil, entre 2016-2017. La clasificación de feminicidios se basó en la Ley nº 13.104/2015. El riesgo relativo se estimó mediante regresión de Poisson y se empleó un modelo jerárquico para la introducción de las variables en los modelos. Los análisis se efectuaron en el software R. De 138 víctimas fatales por agresiones, 52 fueron feminicidios, un 37,7% (IC: 29,4-45,5). Con cada aumento unitario de edad, el riesgo de feminicidio se reducía en un 3% (IC: 0,95-0,99); el riesgo de feminicidio fue un 40% menor (IC: 0,40-0,90) en las mujeres con hasta siete años de escolaridad, en comparación con las que tenían ocho años o más; las mujeres agredidas mediante fuerza corporal tuvieron un riesgo 5,5 (IC: 2,6-11,3) veces mayor de feminicidio, en comparación con las que fueron agredidas con arma de fuego; y un riesgo de feminicidio de 1,4 (IC: 1,1-2,7) quienes fueron asesinadas durante el día, en relación con quienes murieron de noche. La proporción de feminicidio de este estudio fue inferior a las estimaciones previas en Brasil y la carga local de la criminalidad urbana parece explicar parte de esta divergencia. Este estudio demostró que la edad, escolaridad, uso de la fuerza corporal y período del día de la agresión están asociados al feminicidio.

Performance of HIV pre-exposure prophylaxis indirect adherence measures among men who have sex with men and transgender women: Results from the PrEP Brasil Study.

INTRODUCTION: Efficacy of daily emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) for PrEP is strongly dependent on the adherence. We examined the concordance between indirect adherence measures and protective drug levels among participants retained through 48 weeks in the PrEP Brasil Study. METHODS: PrEP Brasil was a prospective, multicenter, open-label demonstration project evaluating PrEP provision for men who have sex with men (MSM) and transgender women (TGW) at higher risk for HIV infection within the setting of Brazilian Public Health System. Three indirect adherence measures were obtained at week 48: medication possession ratio (MPR), pill count and self-report (30-days recall). Tenofovir diphosphate (TFV-DP) concentration in Dried Blood Spot (DBS) was measured at week 48. Areas under (AUC) the receiver operating characteristics (ROC) curve were used to evaluate the concordance between achieving protective drug levels (TFV-DP≥700fmol/punch) and the indirect adherence measures. Youden's index and distance to corner were used to determine the optimal cutoff points for each indirect adherence measure. We calculated sensitivity, specificity, negative (NPV) and positive (PPV) predictive values for the found cutoff points. Finally, Delong test was used to compare AUCs. RESULTS AND DISCUSSION: From April, 2014 to July, 2016, 450 participants initiated PrEP, 375(83.3%) were retained through 48 weeks. Of these, 74% (277/375) had TFV-DP ≥700fmol/punch. All adherence measures discriminated between participants with and without protective drug levels (AUC>0.5). High indirect adherence measure was predictive of protective drug levels (PPV>0.8) while low indirect adherence measure was not predictive of lack of protective drug levels (NPV<0.5). No significant differences were found between the adherence methods (p = 0.44). CONCLUSIONS: Low-burden measurements such as MPR and self-report can be used to predict PrEP adherence in a public health context in Brazil for MSM and TGW retained through 48 weeks.

[Ethnic and racial inequalities in hospital admissions due to avoidable causes in under-five Brazilian children, 2009-2014]. / Iniquidades étnico-raciais nas hospitalizações por causas evitáveis em menores de cinco anos no Brasil, 2009-2014.

There has been a global increase in hospital admissions for primary care-sensitive conditions (PCSCs) as an indicator of effectiveness in primary health care. This article analyzes ethnic and racial inequalities in cause-related hospitalizations in under-five children in Brazil as a whole and the country's five major geographic regions, with an emphasis on PCSCs and acute respiratory infections (ARIs). Using data from the Hospital Information Systems of the Brazilian Unified National Health System (SIH/SUS), 2009-2014, the authors calculated proportions, rates, and rate ratios for PCSCs, adjusted by sex and age after multiple imputation of missing data on color/race. The principal causes of hospitalization were respiratory tract infections (37.4%) and infectious and parasitic diseases (19.3%), and indigenous children were proportionally the most affected. Crude PCSC rates (per 1,000) were highest in indigenous children (97.3; 95%CI: 95.3-99.2), followed by brown or mixed-raced children (40.0; 95%CI: 39.8-40.1), while the lowest rates were in Asiandescendant children (14.8; 95%CI: 14.1-15.5). The highest adjusted rate ratios for PCSCs were seen among indigenous children compared to white children - 5.7 (95%CI: 3.9-8.4) for Brazil as a whole, reaching 5.9 (95%CI: 5.0-7.1) and 18.5 (95%CI: 16.5-20.7) in the North and Central, respectively, compared to white children. ARIs remained as important causes of pediatric hospitalizations in Brazil. Alarming ethnic and racial inequalities were observed in PCSCs, with indigenous children at a disadvantage. Improvements are needed in living conditions, sanitation, and subsistence, as well as guaranteed timely access to high-quality primary health care in the more vulnerable population groups, especially the indigenous peoples of the North and Central, in order to mitigate the health inequalities and meet the guidelines of the SUS and the Brazilian Constitution.

Internacionalmente, observa-se um incremento no uso das internações por condições sensíveis à atenção primária (ICSAP) como indicador de efetividade da atenção primária à saúde. Este artigo analisa as iniquidades étnico-raciais nas internações por causas em menores de cinco anos no Brasil e regiões, com ênfase nas ICSAP e nas infecções respiratórias agudas (IRA). Com dados do Sistema de Informações Hospitalares do Sistema Único de Saúde (SIH/SUS), 2009-2014, calcularam-se proporções por causas, taxas e razões de taxas de ICSAP ajustadas por sexo e idade após a imputação múltipla de dados faltantes de cor/raça. As principais causas de internação foram doenças do aparelho respiratório (37,4%) e infecciosas e parasitárias (19,3%), sendo as crianças indígenas as mais acometidas. As taxas brutas de ICSAP (por 1.000) foram mais elevadas em indígenas (97,3; IC95%: 95,3-99,2), seguidas das pardas (40,0; IC95%: 39,8-40,1), e as menores foram nas amarelas (14,8; IC95%: 14,1-15,5). As maiores razões de taxas ajustadas de ICSAP foram registradas entre crianças de cor/raça indígena e branca - 5,7 (IC95%: 3,9-8,4) no país, atingindo 5,9 (IC95%: 5,0-7,1) e 18,5 (IC95%: 16,5-20,7) no Norte e Centro-oeste, respectivamente. As IRA permanecem como importantes causas de hospitalização em crianças no Brasil. Foram observadas alarmantes iniquidades étnico-raciais nas taxas de ICSAP, com situação de desvantagem para indígenas. São necessárias melhorias nas condições de vida, saneamento e subsistência, bem como garantia de acesso oportuno e qualificado à atenção primária à saúde das populações mais vulneráveis, com destaque para os indígenas no Norte e no Centro-oeste, a fim de minimizar iniquidades em saúde e fazer cumprir as diretrizes do SUS e da Constituição do Brasil.

Internacionalmente, se observa un incremento en las hospitalizaciones por condiciones sensibles a la atención primaria (ICSAP), como un indicador de efectividad de la atención primaria a la salud. Este artículo analiza las inequidades étnico-raciales en las hospitalizaciones por causas evitables em menores de cinco años en Brasil y sus regiones, con énfasis en las ICSAP y en las infecciones respiratorias agudas (IRA). Con datos del Sistema de Informaciones Hospitalarias del Sistema Único de Salud (SIH/SUS), 2009-2014, se calcularon porcentajes por causas, tasas y razones de tasas de ICSAP ajustadas por sexo y edad, tras la imputación múltiple de datos faltantes de color/raza. Las principales causas de hospitalización fueron enfermedades del aparato respiratório (37,4%) e infecciosas y parasitarias (19,3%), siendo los niños indígenas los más afectados. Las tasas brutas de ICSAP (por 1.000) fueron más elevadas en indígenas (97,3; IC95%: 95,3-99,2), seguidas de las mulatos/mestizos (40,0; IC95%: 39,8-40,1), mientras que las menores fueron en las de origen asiática (14,8; IC95%: 14,1-15,5). Las mayores razones de tasas ajustadas de ICSAP fueron en los niños indígenas comparados a los niños de color/raza blanca - 5,7 (IC95%: 3,9-8,4) en el país, alcanzando 5,9 (IC95%: 5,0-7,1) y 18,5 (IC95%: 16,5-20,7) en el Norte y Centro-oeste, respectivamente, en comparación con El color/raza blanca. Las IRA permanecen como importantes causas de hospitalización en niños em Brasil. Se observaron alarmantes inequidades étnico-raciales en las tasas de ICSAP, con situación de desventaja para los indígenas. Se necesitan mejoras en las condiciones de vida, saneamiento y subsistencia, así como la garantía de un acceso oportuno y cualificado a la atención primaria a La salud de las poblaciones más vulnerables, destacando los indígenas en el Norte y Centro-oeste, a fin de minimizar inequidades en salud y hacer cumplir las directrices del SUS y de la Constitución de Brasil.

Sociodemographic and clinical profile of patients with occupational contact dermatitis seen at a work-related dermatology service, 2000 - 2014.

BACKGROUND: Occupational dermatoses are common, especially contact dermatitis. Epidemiological studies on these dermatoses are scarce in Brazil and they are necessary as part of the public policy to protect workers' health. OBJECTIVES: To identify sociodemographic and clinical profile of patients with occupational contact dermatitis seen between 2000 and 2014 at an occupational dermatology service. METHODS: It is a cross-sectional and retrospective study, based on information obtained from the service's database. RESULTS: Of 560 patients with conclusive patch test, 289 (46.9%) presented occupational dermatoses and 213 occupational contact dermatitis with predominance of the allergic type in relation to the irritative type (149:64 respectively). The odds of occupational dermatoses were higher among men and lower among patients aged 50 years or older and with higher level of education. Regarding the possibility of presenting occupational allergic contact dermatitis, only the gender variable was statistically significant. The professions most seen were cleaners, construction workers, painters, mechanics/metallurgists and cooks. The commonest allergens were nickel sulfate, potassium dichromate, cobalt chloride, carba-mix and formaldehyde. STUDY LIMITATIONS: The main limitations of this study are the fact that it was carried out in a tertiary service of occupational dermatoses and the lack of access to some allergens outside the patch test baseline series. CONCLUSIONS: It was possible to identify the sociodemographic and clinical profile of patients with suspected occupational contact dermatitis seen at the Service, beyond the professional groups and allergens related to a high risk of occupational contact dermatitis in this population.
