When Ethics and the Law Collide: A Multicenter Demonstration Cohort Study of Pre-Exposure Prophylaxis Provision to Adolescent Men Who Have Sex With Men and Transgender Women in Brazil.

PURPOSE: To explore legal and ethical challenges related to adolescents' participation in human immunodeficiency virus (HIV) research that may affect their best interests. METHODS: We analyzed the ethical principles and legal aspects of the participation of 15-17-year-old men who have sex with men and transgender women in the pre-exposure prophylaxis (PrEP) 1519 study, a PrEP demonstration cohort study in three Brazilian cities. The analyses of ethics review committees' (ERCs) evaluations and court decisions followed ethical and human rights principles. An HIV vulnerability score was created, and descriptive statistics and multivariate logistic regression were performed using data from 347 participants. RESULTS: The ERCs evaluated the benefits and risks of research participation, all finding that the benefits outweighed the risks. ERCs deferred responsibility for decisions about waiving parental consent to the judiciary. State courts reached different decisions about waiving parental consent, reflecting variation in recognition of adolescents' evolving capacities and the adolescent as a subject of sexual rights and the primary agent capable of deciding on their health and best interests. The most vulnerable adolescent participants were found in sites where the blanket waiver was in place. DISCUSSION: Judicializing the ethical review process is detrimental to fulfilling the ethical principle of justice and vulnerable adolescents' access to health research. ERCs must be sufficiently independent and autonomous and have the capacity to respect, protect, and help fulfill the rights of participants while ensuring the generation of adequate evidence to inform public health practice.

Adherence, Safety, and Feasibility of HIV Pre-Exposure Prophylaxis Among Adolescent Men Who Have Sex With Men and Transgender Women in Brazil (PrEP1519 Study).

PURPOSE: To evaluate the adherence, safety, and feasibility of pre-exposure prophylaxis (PrEP) in real-world settings among adolescent men who have sex with men (AMSM) and transgender women (ATGW). METHODS: PrEP1519 is a single-arm, multicentric demonstration cohort study of daily oral PrEP among AMSM and ATGW aged 15 to 19 years in Brazil. Study visits occurred at baseline, weeks 4, 12, and then quarterly until 96 weeks. Descriptive statistics and a mixed logistic model for longitudinal data evaluated the factors associated with high adherence. RESULTS: One thousand sixteen AMSM and ATGW accessed the PrEP1519 clinics. Of those, 998 (98.2%) underwent clinical triage. Forty one were diagnosed with human immunodeficiency viruses (HIV) at baseline (4.0%) and 79 (7.9%) were not eligible for PrEP. Of the 878, 795 (90.5%) enrolled in PrEP, 82 (10.3%) were lost to follow-up, and 713 were included. There was no significant decrease in creatinine clearance; only two participants had grade-III aspartate aminotransferase elevation. Incident HIV infection occurred in eight participants (incidence rate [IR] = 1.64 per 100 person-years [PY]): two in 15-17 years (IR = 2.24 per 100 PY) and six in 18-20 years (IR = 1.51 per 100 PY). PrEP adherence was higher among those with more years of schooling, those reporting no difficulties in PrEP use due to side effects, and who had low HIV risk perception in the past three months. DISCUSSION: PrEP for AMSM and ATGW was safe and feasible in real-world settings. However, a higher IR among young adolescents and a higher adherence among less vulnerable people indicate the need for greater care, considering the specificities of this age group.

Suppression of HIV in the first 12 months of antiretroviral therapy: a comparative analysis of dolutegravir- and efavirenz-based regimens.

OBJECTIVE: To compare viral suppression in treatment-naïve adults starting antiretroviral therapy with dolutegravir (50mg)- and efavirenz (600mg)-based regimens. METHODS: We analyzed secondary data from Brazilian health information systems of people living with human immunodeficiency virus who started antiretroviral therapy between 2015 and 2017 in Minas Gerais, Brazil. The outcome was viral suppression, defined as the achievement of the first viral load <50 copies/mL within 12 months after initiating antiretroviral therapy. This outcome was also compared with viral load <1,000 copies/mL and analyzed in two scenarios: intention-to-treat versus per-protocol. Time to viral suppression and adjusted odds ratio accompanied by 95% confidence intervals were estimated. RESULTS: Of the 2,599 participants enrolled, 77.5% were men, and the median age was 34 years. In the intention-to-treat analysis, viral suppression was 58.1% for efavirenz and 76.7% for dolutegravir. People living with HIV on dolutegravir-based regimen were more likely to achieve viral suppression (aOR: 2.44; 95%CI: 2.01-2.95) and had a shorter median time to viral suppression (p<0.0001). Antiretroviral therapy initiation within <120 days, baseline CD4⁺T-cells ≥200 cells/mm3, and viral load <100,000 copies/mL had higher odds of viral suppression. According to the per-protocol analysis, viral suppression ≥90% was observed by considering viral load <1,000 copies/mL. CONCLUSION: Our study demonstrated that viral suppression improved after introducing dolutegravir, although the proportion of patients with viral load <50 copies/mL was lower than expected. Improved access to routine viral load examinations and continuous surveillance of the effectiveness of antiretroviral therapy should be considered.

Violence, discrimination, and sexual health practices among adolescent men who have sex with men, transgender women and travestis in three cities in Brazil / Violência, discriminação e práticas de saúde sexual entre homens adolescentes que fazem sexo com homens, mulheres transgêneros e travestis em três cidades do Brasil / Violencia, discriminación y prácticas de salud sexual entre hombres adolescentes que tienen sexo con hombres, mujeres transgénero y travestis en tres ciudades de Brasil

The HIV epidemic has a disproportionate impact on adolescent and young men who have sex with men (AMSM) and transgender women and travestis (ATGW), with an increased HIV prevalence over the last 10 years. Violence affects the lives of these populations, undermining their ability to self-care and making them more vulnerable to HIV infection. In this study, we aimed to examine the association between different types of victimization by violence and discrimination and sexual health practices of these adolescent populations in steady and casual relationships. We conducted a cross-sectional study using baseline data from the cohort of PrEP1519 project. We used the mean score of sexual health practices as our outcome and the cumulative score of discrimination (within family, community, education, religious, online and public spaces) and violence (physical, sexual and intimate partner) as our exposure variable. We performed linear regression analyses to estimate the association between exposure and outcome. We found that 90% of AMSM and 95% of ATGW experienced at least one form of violence in the three months prior to this study and about 45% of ATGW suffered sexual violence during the same period. Experiencing discrimination within healthcare settings (from facilities or providers) was negatively associated with sexual health practices. Discrimination and violence negatively affect sexual health practices. HIV prevention and care of AMSM and ATGW people should involve listening to their experiences and addressing discrimination and violence in this population.

A epidemia de HIV afeta desproporcionalmente homens adolescentes que fazem sexo com homens (AHSH) e mulheres transgênero e travestis. Nos últimos 10 anos, a prevalência do HIV aumento. A violência afeta a vida dessas populações adolescentes, comprometendo sua capacidade de autocuidado e tornando-as mais vulneráveis à infecção pelo HIV. Este estudo buscou examinar a associação entre diferentes tipos de vitimização por violência e discriminação e práticas de saúde sexual entre essas populações adolescentes em relacionamentos estáveis e casuais. Realizamos um estudo transversal usando dados basais do estudo de coorte PrEP1519. Usamos o escore médio de práticas de saúde sexual como desfecho e o escore cumulativo de discriminação (familiar, comunitária, educacional, religiosa, online e em espaços públicos) e violência (parceiro físico, sexual e íntimo) como variável de exposição. Realizamos análises de regressão linear para estimar a associação entre exposição e desfecho. No todo, 90% dos AHSH e 95% dos mulheres transgênero e travestis sofreram pelo menos uma forma de violência nos três meses anterior à pesquisa e cerca de 45% dos mulheres transgênero e travestis sofreram violência sexual no mesmo período. Vivenciar discriminação dentro de ambientes de cuidados de saúde (instituições ou provedores) foi negativamente associado às práticas de saúde sexual. A discriminação e a violência afetam negativamente práticas de saúde sexual. A prevenção contra o HIV e o cuidado a AHSH e mulheres transgênero e travestis devem escutar suas experiências e enfrentar a discriminação e da violência nessa população.

La violencia afecta la vida de estas poblaciones adolescentes, comprometiendo su capacidad de autocuidado y haciéndolas más vulnerables a la infección por VIH. Este estudio buscó examinar la asociación entre los diferentes tipos de victimización por violencia y discriminación y las prácticas de salud sexual entre estas poblaciones adolescentes en relaciones estables y casuales. Realizamos un estudio transversal utilizando datos basales del estudio de cohorte PrEP1519. Utilizamos el puntaje promedio de las prácticas de salud sexual como resultado y el puntaje acumulativo de discriminación (familiar, comunitario, educativo, religioso, en línea y en espacios públicos) y la violencia (pareja física, sexual e íntima) como variable de exposición. Realizamos análisis de regresión lineal para estimar la asociación entre la exposición y el resultado. En total, el 90 % de los AHSH y el 95 % de los mujeres transgénero y travestis experimentaron al menos una forma de violencia en los tres meses anteriores a la encuesta, y alrededor del 45 % de los mujeres transgénero y travestis experimentaron violencia sexual en el mismo período. Experimentar discriminación dentro de los ambientes de atención médica (instituciones o proveedores) se asoció negativamente con las prácticas de salud sexual. La discriminación y la violencia afectan negativamente las prácticas de salud sexual. La prevención contra el VIH y el cuidado a AHSH y mujeres transgénero y travestis deben escuchar sus experiencias y hacer frente a la discriminación y la violencia en esa población.

Prevalence of syphilis and sexual behavior and practices among adolescents MSM and TrTGW in a Brazilian multi-center cohort for daily use of PrEP / Prevalência de sífilis e comportamento e práticas sexuais entre adolescentes HSH e travestis e mulheres transgênero em um estudo de coorte multicêntrico brasileiro sobre uso diário de PrEP / Prevalencia de sífilis, comportamiento sexual y prácticas entre adolescentes HSH y TrTGW en una cohorte multicéntrica brasileña para el uso diario de PrEP

Syphilis has reemerged as a serious public health problem in Brazil and worldwide, disproportionately affecting men who have sex with men (MSM) and travestis and transgender women (TrTGW). Studies on sexually transmitted infections (STI) in adolescents from these key populations are relatively scarce. This is a Brazilian multi-center, cross study with prevalence analysis, using as baseline the PrEP1519 cohort of sexually active MSM and TrTGW adolescents, recruited from April 2019 to December 2020. Analyses were made using the dimensions of vulnerability to STI/HIV and logistic regression models were conducted to estimate the odds ratios of the association between the predictor variables and positive treponemal test for syphilis at the moment of entry in the study. In total, 677 participants were analyzed; participants' median age was 18.9 years (IQR: 18.1-19.5); 70.5% (477) self-declared as black; 70.5% (474), as homosexuals/gays; and 48 (7.1%), as trans women or travestis. The baseline prevalence of syphilis was 21.3%. In the final logistic regression model, higher chance of syphilis was associated with: self-reported episode of STI in the last 12 months (OR = 5.92; 95%CI: 3.74-9.37), sex worker (OR = 3.39; 95%CI: 1.32-8.78), and < 11 years of schooling (OR = 1.76; 95%CI: 1.13-2.74). The prevalence of syphilis among MSM/TrTGW adolescents aged from 15 to 19 years was alarming, much higher than the described for the general population within this age range and associated with vulnerability factors. This reinforces the urgent need to strengthen public health programs to debate about race, gender, sexuality, and prevention.

São relativamente escassos os estudos sobre infecções sexualmente transmissíveis (IST) entre adolescentes pertencentes a essas populações-chave. O estudo transversal multicêntrico brasileiro analisou a prevalência de sífilis na linha de base da coorte PrEP15-19 de HSH, travestis e mulheres transgênero adolescentes, sexualmente ativos, recrutados entre abril de 2019 e dezembro de 2020. As análises foram realizadas com as dimensões de vulnerabilidade a ISTs/HIV, e modelos de regressão logística foram construídos para estimar as razões de chances da associação entre as variáveis preditoras e um teste treponêmico positivo para sífilis na entrada do estudo. Foram analisados 677 participantes. A idade mediana era 18,9 anos (IIQ: 18,1-19,5), 70,5% (477) se autoidentificaram como pretos, 70,5% (474) como homossexuais/gays e 48 (7,1%) como mulheres trans ou travestis. A prevalência de sífilis na linha de base era 21,3%. No modelo final de regressão logística, as seguintes variáveis estiveram associadas com chances maiores de sífilis: autorrelato de episódio de IST nos últimos 12 meses (OR = 5,92; IC95%: 3,74-9,37), profissional do sexo (OR = 3,39; IC95%: 1,32-8,78) e menos de 11 anos de escolaridade (OR = 1,76; IC95%: 1,13-2,74). A prevalência de sífilis entre HSH, travestis e mulheres transgênero adolescentes entre 15 e 19 anos de idade foi alarmante, muito acima da taxa relatada na população geral nesta faixa etária, e esteve associada a fatores de vulnerabilidade. Os achados reforçam a necessidade urgente de fortalecer os programas de saúde pública com a discussão sobre raça, gênero, sexualidade e prevenção.

When prevention is the best remedy: HIV pre-exposure prophylaxis (PrEP) among adolescents gays and transgender women in Belo Horizonte, Minas Gerais State, Brazil / Quando a prevenção é o melhor remédio: profilaxia pré-exposição do HIV (PrEP) entre adolescentes gays e mulheres transgênero em Belo Horizonte, Minas Gerais, Brasil / Cuando la prevención es el mejor remedio: profilaxis previa a la exposición al VIH (PrEP) entre adolescentes gays y mujeres transgénero en Belo Horizonte, Minas Gerais, Brasil

Based on the incorporation of pre-exposure prophylaxis (PrEP) as an HIV prevention strategy and considering the need to comprehend the use of medication among young people, this article analyzes narratives of gay men and transgender women from Belo Horizonte, Minas Gerais State, Brazil, participating in the PrEP1519 study. This is a qualitative research, based on the interpretative anthropology, developed by 10 in-depth interviews with PrEP users followed-up for at least three months between October and November 2019. The results showed that the drug was seen as the main motivation for participating in the study and as a strategy combined with the use of condoms, whether as additional prevention, or assuming the leading role. The medication revealed signs built by the gender performances and their relation to other medications, especially the experience of trans girls in hormonal therapy. Regarding the socialization of the use of PrEP, the narratives showed that there was no secret between the couples, which did not meant that stigmas on the association with HIV did not exist, mainly in the virtual context. In the family environment, they reported questions about the preventive function of the medication and the voluntary nature of the participation in the study. The youth's narratives revealed plural meanings of the medication and its social use, composing both the boys' and girls' performances. The signs attributed to the medication indicated that in addition to maintenance of health, the medication improves life and sexual freedom.

A pesquisa qualitativa, baseada na antropologia interpretativa, foi desenvolvida através de 10 entrevistas em profundidade com usuários de PrEP acompanhados durante pelo menos três meses entre outubro e novembro de 2019. Os resultados mostraram que o medicamento era visto como a principal motivação para participar no estudo e como estratégia combinada com o uso de preservativos, seja como prevenção adicional ou assumindo o papel principal. A medicação revelou sinais elaborados pelas performances de gênero e sua relação com outros medicamentos, principalmente a experiência de meninas trans em uso de hormonioterapia. Quanto à socialização do uso da PrEP, as narrativas mostraram que não havia segredo entre os casais, o que não significava a inexistência de estigma em relação à associação com HIV, principalmente no contexto virtual. No ambiente familiar, os participantes relatavam questões sobre a função preventiva da medicação e a natureza voluntária da participação no estudo. As narrativas dos jovens revelaram sentidos plurais atribuídos à medicação e ao seu uso social, compondo as performances tanto dos meninos quanto das meninas. Os sinais atribuídos à medicação indicaram que além da manutenção da saúde, a medicação melhora a vida e a liberdade sexual dos usuários.

Suppression of HIV in the first 12 months of antiretroviral therapy: a comparative analysis of dolutegravir- and efavirenz-based regimens

ABSTRACT Objective To compare viral suppression in treatment-naïve adults starting antiretroviral therapy with dolutegravir (50mg)- and efavirenz (600mg)-based regimens. Methods We analyzed secondary data from Brazilian health information systems of people living with human immunodeficiency virus who started antiretroviral therapy between 2015 and 2017 in Minas Gerais, Brazil. The outcome was viral suppression, defined as the achievement of the first viral load <50 copies/mL within 12 months after initiating antiretroviral therapy. This outcome was also compared with viral load <1,000 copies/mL and analyzed in two scenarios: intention-to-treat versus per-protocol. Time to viral suppression and adjusted odds ratio accompanied by 95% confidence intervals were estimated. Results Of the 2,599 participants enrolled, 77.5% were men, and the median age was 34 years. In the intention-to-treat analysis, viral suppression was 58.1% for efavirenz and 76.7% for dolutegravir. People living with HIV on dolutegravir-based regimen were more likely to achieve viral suppression (aOR: 2.44; 95%CI: 2.01-2.95) and had a shorter median time to viral suppression (p<0.0001). Antiretroviral therapy initiation within <120 days, baseline CD4⁺T-cells ≥200 cells/mm3, and viral load <100,000 copies/mL had higher odds of viral suppression. According to the per-protocol analysis, viral suppression ≥90% was observed by considering viral load <1,000 copies/mL. Conclusion Our study demonstrated that viral suppression improved after introducing dolutegravir, although the proportion of patients with viral load <50 copies/mL was lower than expected. Improved access to routine viral load examinations and continuous surveillance of the effectiveness of antiretroviral therapy should be considered.

RT-qPCR-based pool testing for the diagnosis of COVID-19

ABSTRACT This study proposes a strategy for large-scale testing among a large number of people for the early diagnosis of COVID-19 to elucidate the epidemiological situation. Pool testing involves the analysis of pooled samples. This study aimed to discuss a reverse transcription technique followed by quantitative real-time polymerase chain reaction using pool testing to detect SARS-CoV-2 in nasopharyngeal swab samples. The study proposes an innovative diagnostic strategy that contributes to resource optimization, cost reduction, and improved agility of feedback from results.

Evaluation from a B-cell epitope-based chimeric protein for the serodiagnosis of tegumentary and visceral leishmaniasis.

The diagnosis of leishmaniasis presents problems due to the variable sensitivity and/or specificity of tests. In addition, high levels of anti-parasite antibodies can remain after treatment, making it difficult to conduct a prognostic follow-up of patients. In this context, it is necessary to identify new candidates to be examined for the sensitive and specific diagnosis of the disease. In the present study, four Leishmania proteins, previously shown as antigenic for tegumentary leishmaniasis (TL), were evaluated, and their linear specific B-cell epitopes were predicted and used to generate a new gene codifying chimeric protein called ChimB, which was cloned, and the recombinant version was expressed, purified, and evaluated in ELISA (Enzyme-Linked Immunosorbent Assay) to diagnose TL and visceral leishmaniasis (VL). A total of 220 human serum samples were used, and, when ChimB was used, results showed sensitivity, specificity, and positive and negative predictive values of 100% for the diagnosis of both diseases; however, when using peptides, the sensitivity values reached from 28.0% to 57.3% and specificity varied from 16.3% to 83.7%. A soluble Leishmania extract (SLA) showed sensitivity and specificity values of 30.7% and 45.9%, respectively. The area under the curve (AUC) value for ChimB was 1.0, while for synthetic peptides, this value reached between 0.502 and 0.635, whereas for SLA, the value was of 0.589. Serological assays using sera samples collected before and after treatment showed significant reductions in the anti-ChimB antibody levels after therapy, suggesting a prognostic role of this recombinant antigen. In conclusion, preliminary data suggest the use from ChimB as a potential candidate for the diagnosis and prognosis of leishmaniasis.

Detection of SARS-CoV-2 through pool testing for COVID-19: an integrative review.

INTRODUCTION: The pool testing technique optimizes the number of tests performed and reduces the delivery time of results, which is an interesting strategy for the health crisis caused by the COVID-19 pandemic. This integrative review investigated studies in which pool testing was carried out for epidemiological or screening purposes to analyze its clinical or cost effectiveness and assessed the applicability of this method in high-, middle-, and low-income countries. METHODS: This integrative review used primary studies published in the MEDLINE, EMBASE, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), and Cochrane Library databases. RESULTS: A total of 435 studies were identified: 35.3% were carried out in Asia, 29.4% in Europe, 29.4% in North America, and 5.9% in Oceania. CONCLUSIONS: This review suggests that pool testing in the general population may be a useful surveillance strategy to detect new variants of SARS-CoV-2 and to evaluate the period of immunogenicity and global immunity from vaccines.

ChimLeish, a new recombinant chimeric protein evaluated as a diagnostic and prognostic marker for visceral leishmaniasis and human immunodeficiency virus coinfection.

Visceral leishmaniasis (VL) is a neglected tropical disease of global importance caused by parasites of the genus Leishmania, and coinfection with human immunodeficiency virus (HIV) is common in countries where both diseases are endemic. In particular, widely used immunological tests for VL diagnosis have impaired sensitivity (Se) and specificity (Sp) in VL/HIV coinfected patients and there is also cross-reactivity with other endemic diseases, e.g., Chagas disease, malaria, and tuberculosis. To develop new antigens to improve the diagnosis of VL and VL/HIV coinfection, we predicted eight specific B-cell epitopes of four Leishmania infantum antigens and constructed a recombinant polypeptide chimera antigen called ChimLeish. A serological panel of 195 serum samples was used to compare the diagnostic capabilities of ChimLeish alongside the individual synthetic peptides. ChimLeish reacted with sera from all VL and VL/HIV coinfected patients [Se = 100%; Sp = 100%; area under the curve (AUC) = 1.0]. Peptides showed lower reactivities (Se = 76.8 to 99.2%; Sp = 67.1 to 95.7%; AUC between 0.87 and 0.98) as did a L. infantum antigenic preparation used as an antigen control (Se = 56.8%; Sp = 69.5%: AUC = 0.45). Notably, ChimLeish demonstrated a significant reduction (p < 0.05) of anti-ChimLeish antibodies after treatment and cure of a small number of patients. Although only a limited serological panel was tested, preliminary data suggest that ChimLeish should be evaluated in larger sample studies for the diagnosis of VL and VL/HIV coinfection.

Potential of recombinant LiHyQ, a novel Leishmania infantum protein, for the diagnosis of canine visceral leishmaniasis and as a diagnostic and prognostic marker for human leishmaniasis and human immunodeficiency virus co-infection: A preliminary study.

Laboratory diagnosis of leishmaniasis shows variable efficacy in detecting infected mammalian hosts and there is a need to identify suitable antigens to improve the accuracy of diagnostic tests. In the present study, a L. infantum hypothetical protein called LiHyQ was evaluated for the diagnosis of tegumentary (TL) and visceral (VL) leishmaniasis using canine and human samples. A collection of dog sera (n=155) were tested and contained samples from asymptomatic (n=20) and symptomatic (n=25) VL animals, from healthy dogs living in endemic (n=25) or non-endemic (n=25) areas of disease, from Leish-Tec® vaccinated dogs (n=20) or from dogs infected with Ehrlichia canis (n=15), Babesia canis (n=10) and Trypanosoma cruzi (n=15). Sensitivity (Se), Specificity (Sp), Positive Predictive Value (PPV) and Negative Predictive Value (NPV) of 100% were observed for rLiHyQ with these samples, whereas the Se, Sp, PPV and NPV values with L. infantum Soluble Leishmania Antigen (SLA) preparation were 60.0%, 99.0%, 96.0% and 86.0%, respectively. A collection of human sera (n=305) were tested and contained samples from TL (n=50) and VL (n=40) patients, from VL/HIV co-infected patients (n=35), from patients infected with HIV alone (n=30), Chagas Disease (n=30), malaria (n=10), tuberculosis (n=10), paracoccidioidomycosis (n=15), leprosy (n=30) or aspergillosis (n=15); and from healthy subjects (n=40). Se, Sp, PPV and NPV values of 100% were observed for rLiHyQ with these samples, whereas the Se, Sp, PPV and NPV values with SLA were 58.0%, 76.0%, 50.0% and 82.0%, respectively. The antibody reactivity against the protein was compared with commercial kits, and the kappa index varied from 0.95 to 1.00 for rLiHyQ, and of 0.55 to 0.82 for the kits. In addition, the serological follow-up of treated patients showed a significant reduction in rLiHyQ-specific IgG antibody levels. All canine and human samples were tested at the same time using the same reagents, in order to reduce experimental variation and interference in data interpretation. In conclusion, our preliminary data suggest a diagnostic and prognostic role for rLiHyQ against leishmaniasis.

Aumento de Óbitos Domiciliares devido a Parada Cardiorrespiratória em Tempos de Pandemia de COVID-19 / Increased Home Death Due to Cardiopulmonary Arrest in Times of COVID-19 Pandemic

Resumo Fundamento As doenças cardiovasculares constituem um grupo importante de causas de morte no Brasil. As doenças isquêmicas do coração são as principais causas de parada cardiorrespiratória, levando a um impacto na mortalidade devido às doenças cardiovasculares no sistema de saúde. Objetivo Avaliar o número de óbitos domiciliares por parada cardiorrespiratória notificados pelo Serviço de Atendimento Móvel de Urgência (SAMU) em março de 2018, 2019 e 2020. Métodos Trata-se de um estudo observacional realizado a partir da análise de dados de mortalidade por parada cardiorrespiratória de cidadãos atendidos pelo SAMU em Belo Horizonte, Minas Gerais, Brasil. Foram analisadas as características sociais e clínicas e as informações de ocorrência. Foi avaliada a taxa de mortalidade por parada cardiorrespiratória em relação ao número total de atendimentos. Foi considerado um nível de significância de 95%. Resultados Houve um aumento nos óbitos domiciliares por parada cardiorrespiratória em março de 2020, em comparação com março de 2018 (p < 0,001) e março de 2019 (p = 0,050). Dos óbitos relatados em 2020, 63,8% dos pacientes tinham 60 anos ou mais; 63,7% das ocorrências foram à tarde e aproximadamente 87% dos casos de parada cardiorrespiratória notificados apresentavam comorbidades clínicas, com hipertensão arterial sistêmicas e parada cardíaca correspondendo a 22,87% e 13,03% dos casos relatados, respectivamente. A maioria da amostra avaliada deste estudo não teve acompanhamento médico (88,7%).

Abstract Background Cardiovascular diseases constitute an important group of causes of death in the country. Ischemic heart diseases that are the main causes of cardiopulmonary arrest, leading to an impact on the mortality of the cardiovascular diseases in the health system. Objective Assess the number of home deaths by cardiopulmonary arrest notified by the Mobile Emergency Medical Service (SAMU) in March 2018, 2019 and 2020. Methods Observational study carried out from the analysis of cardiopulmonary arrest mortality data of citizens assisted by SAMU in Belo Horizonte, Minas Gerais, Brazil. Social and clinical characteristics and occurrence information of the patients were analyzed. The mortality rate due to cardiopulmonary arrest in relation to the total number of attendances was assessed. A significance level of 95% was considered. Results There was increase of home deaths due to cardiopulmonary arrest in March 2020 compared to March 2018 (p<0.001) and March 2019 (p=0.050). Of the deaths reported in 2020, 63.8% of the patients were aged 60 years or older, 63.7% of the occurrences were performed in the afternoon and approximately 87% of the cardiopulmonary arrest notified had associated clinical comorbidities, with systemic arterial hypertension and heart failure represented by 22.87% and 13.03% of the reported cases, respectively. The majority of the evaluated sample of this study did not have any medical care follow-up (88.7%). Conclusion Considering the increase in the number of the deaths, we suggest reflections and readjustments regarding the monitoring of chronic non-transmissible diseases during a pandemic, as well as improvements in death surveillance.

Diagnostic application of sensitive and specific phage-exposed epitopes for visceral leishmaniasis and human immunodeficiency virus coinfection.

The diagnosis of visceral leishmaniasis (VL) has improved with the search of novel antigens; however, their performance is limited when samples from VL/human immunodeficiency virus (HIV)-coinfected patients are tested. In this context, studies conducted to identify more suitable antigens to detect both VL and VL/HIC coinfection cases should be performed. In the current study, phage display was performed using serum samples from healthy subjects and VL, HIV-infected and VL/HIV-coinfected patients; aiming to identify novel phage-exposed epitopes to be evaluated with this diagnostic purpose. Nine non-repetitive and valid sequences were identified, synthetized and tested as peptides in enzyme-linked immunosorbent assay experiments. Results showed that three (Pep2, Pep3 and Pep4) peptides showed excellent performance to diagnose VL and VL/HIV coinfection, with 100% sensitivity and specificity values. The other peptides showed sensitivity varying from 50.9 to 80.0%, as well as specificity ranging from 60.0 to 95.6%. Pep2, Pep3 and Pep4 also showed a potential prognostic effect, since specific serological reactivity was significantly decreased after patient treatment. Bioinformatics assays indicated that Leishmania trypanothione reductase protein was predicted to contain these three conformational epitopes. In conclusion, data suggest that Pep2, Pep3 and Pep4 could be tested for the diagnosis of VL and VL/HIV coinfection.

The impact of COVID-19 pandemic course in the number and severity of hospitalizations for other natural causes in a large urban center in Brazil.

The COVID-19 pandemic may indirectly impact hospitalizations for other natural causes. Belo Horizonte is a city with 2.5 million inhabitants in Brazil, one of the most hardly-hit countries by the pandemic, where local authorities monitored hospitalizations daily to guide regulatory measures. In an ecological, time-series study, we investigated how the pandemic impacted the number and severity of public hospitalizations by other natural causes in the city, during 2020. We assessed the number and proportion of intensive care unit (ICU) admissions and in-hospital deaths for all-natural causes, COVID-19, non-COVID-19 natural causes, and four disease groups: infectious, respiratory, cardiovascular, and neoplasms. Observed data from epidemiological week (EW) 9 (first diagnosis of COVID-19) to EW 48, 2020, was compared to the mean for the same EW of 2015-2019 and differences were tested by Wilcoxon rank-sum test. The five-week moving averages of the studied variables in 2020 were compared to that of 2015-2019 to describe the influence of regulatory measures on the indicators. During the studied period, there was 54,722 hospitalizations by non-COVID-19 natural causes, representing a 28% decline compared to the previous five years (p<0.001). There was a concurrent significant increase in the proportion of ICU admissions and deaths. The greater reductions were simultaneous to the first social distancing decree or occurred in the peak of COVID-19 hospitalizations, suggesting different drivers. Hospitalizations by specific causes decreased significantly, with greater increase in ICU admissions and deaths for infectious, cardiovascular, and respiratory diseases than for neoplasms. While the first reduction may have resulted from avoidance of contact with healthcare facilities, the second reduction may represent competing causes for hospital beds with COVID-19 after reopening of activities. Health policies must include protocols to address hospitalizations by other causes during this or future pandemics, and a plan to face the rebound effect for elective deferred procedures.
