ABSTRACT Conditions related to the acquired immune deficiency syndrome (AIDS) are still a significant cause of morbidity and mortality among people living with HIV (PLHIV). Longer survival in this population were reported to increase the risk of developing noncommunicable chronic diseases (NCDs). This study aimed to estimate the survival and causes of death according to age group and sex among PLHIV monitored at two referral centers in the Northeastern Brazil. This is a prospective, retrospective cohort with death records from 2007 to 2018, based on a database that registers causes of death using the International Classification of Disease (ICD-10), which were subsequently coded following the Coding Causes of Death in HIV (CoDe). A total of 2,359 PLHIV participated in the study, with 63.2% being men, with a follow-up period of 13.9 years. Annual mortality rate was 1.46 deaths per 100 PLHIV (95% CI: 1.33 – 1.60) with a frequency of 20.9%. Risk of death for men increased by 49% when compared to women, and the risk of death in PLHIV increased by 51% among those aged 50 years and over at the time of diagnosis. It was observed that 73.5% accounted for AIDS-related deaths, 6.9% for non-AIDS defining cancer, 6.3% for external causes, and 3.2% for cardiovascular diseases. Among the youngest, 97.2% presented an AIDS-related cause of death. Highest frequency of deaths from neoplasms was among women and from external causes among men. There is a need for health services to implement strategies ensuring greater adherence to treatment, especially among men and young people. Moreover, screening for chronic diseases and cancer is essential, including the establishment of easily accessible multidisciplinary care centers that can identify and address habits such as illicit drug use and alcoholism, which are associated with violent deaths.

ABSTRACT This review aimed to provide an update on the morphological and/or functional abnormalities related to congenital Zika virus (ZIKV) infection, based on primary data from studies conducted in Brazil since 2015. During the epidemic years (2015-2016), case series and pediatric cohort studies described several birth defects, including severe and/or disproportionate microcephaly, cranial bone overlap, skull collapse, congenital contractures (arthrogryposis and/or clubfoot), and visual and hearing abnormalities, as part of the spectrum of Congenital Zika Syndrome (CZS). Brain imaging abnormalities, mainly cortical atrophy, ventriculomegaly, and calcifications, serve as structural markers of CZS severity. Most case series and cohorts of microcephaly have reported the co-occurrence of epilepsy, dysphagia, orthopedic deformities, motor function impairment, cerebral palsy, and urological impairment. A previous large meta-analysis conducted in Brazil revealed that a confirmed ZIKV infection during pregnancy was associated with a 4% risk of microcephaly. Additionally, one-third of children showed at least one abnormality, predominantly identified in isolation. Studies examining antenatally ZIKV-exposed children without detectable abnormalities at birth reported conflicting neurodevelopmental results. Therefore, long-term follow-up studies involving pediatric cohorts with appropriate control groups are needed to address this knowledge gap. We recognize the crucial role of a national network of scientists collaborating with international research institutions in understanding the lifelong consequences of congenital ZIKV infection. Additionally, we highlight the need to provide sustainable resources for research and development to reduce the risk of future Zika outbreaks. andor or (ZIKV 2015 20152016, 20152016 2016 , (2015-2016) defects overlap collapse arthrogryposis clubfoot, clubfoot clubfoot) CZS. .

Abstract Objective: To assess the protective effect of exclusive breastfeeding and the effectiveness of maternal vaccination in reducing pertussis-like illness. Method: This was a case-control study conducted in sentinel hospitals for pertussis in Recife between July 2016 and July 2018. Cases included children aged under six months with symptoms compatible with pertussis (pertussis-like illness). Controls included children aged under six months, living in the metropolitan region of Recife with no diagnosis of pertussis-like illness and matched by the same hospital and birth date. Results: Seventy-three cases and 194 controls were included. The diagnosis of pertussis-like illness was predominantly clinical (97,2%). Amongst the main symptoms, paroxysmal cough was observed in 95.89% of cases and vomiting in 53.4%. There were 29 hospitalized cases and no deaths. Out of the 73 cases, 47 were born to mothers vaccinated against pertussis during pregnancy, and the mothers of 144 of the 194 controls had been vaccinated. The protective effect of breastfeeding was of 74% (95% CI;38%, 89%). Children younger than six months, who were exclusively breastfed and with mothers vaccinated against pertussis during pregnancy were 5 times less likely to develop pertussis-like illness, corresponding to a protection of 79% (95% CI;31%, 94%). The effectiveness of maternal vaccination against pertussis-like illness in children under six months was low (27%) and not statistically significant (CI 95%; −34% a 60%). Conclusions: Exclusive breastfeeding protects children under six months from pertussis-like illness and may be enhanced when associated with maternal vaccination. These strategies should be encouraged because they also protect against pertussis-like illnesses.

Resumo Mesmo no período em que a pandemia de Covid-19 encontrava-se em crescimento no Nordeste do Brasil, iniciou-se a adoção de medidas de flexibilização do distanciamento social. O objetivo do estudo é o de avaliar a pertinência das propostas de flexibilização, tomando-se em conta a situação da pandemia em cada local e o momento em que foram adotadas. Tendo como referência as diretrizes da OMS, foram construídos e analisados indicadores operacionais para cada diretriz, no contexto da região Nordeste. Para análise do comportamento da epidemia, conforme indicadores selecionados, foram usadas técnicas de Joinpoint Trend Analysis, mapas de calor, razão de taxas e comparação da tendência temporal entre capitais e interior dos estados. O pico do crescimento semanal ocorreu em maio-julho/2020 (semanas epidemiológicas 19 a 31). Na maioria das capitais não se observou tendência decrescente simultânea do número de casos e óbitos nos 14 dias prévios à flexibilização. Em todos os estados o quantitativo de testes realizados foi insuficiente. Na semana epidemiológica 24 os percentuais estaduais de ocupação de leitos de UTI/Covid-19 foram próximos ou superiores 70%. A situação epidemiológica das nove capitais dos estados do Nordeste, no momento em que a decisão de flexibilização foi tomada, mostra que nenhuma delas atendia aos critérios e parâmetros recomendados pela OMS.

Abstract Even in the period when the Covid-19 pandemic was on the rise in the Northeast of Brazil, the relaxation of social distancing measures was introduced. The scope of the study is to assess, in the light of the epidemiological-sanitary situation in the region, the suitability of relaxation of social distancing measures. Based on the WHO guidelines for relaxation of social distancing, operational indicators were created and analyzed for each guideline in the context of the Northeast. To analyze the behavior of the epidemic, according to selected indicators, Joinpoint trend analysis techniques, heat maps, rate ratios and time trends between capitals and the state interior were compared. The weekly growth peak of the epidemic occurred in May-July 2020 (epidemiological weeks 19 to 31). In most capitals, there was no simultaneous downward trend in the number of cases and deaths in the 14 days prior to flexibilization. In all states the number of tests performed was insufficient. In epidemiological week 24, the state percentages of ICU/Covid-19 bed occupancy were close to or above 70%. The epidemiological situation of the nine Northeastern state capitals analyzed here did not meet criteria and parameters recommended by the World Health Organization for the relaxation of social distancing measures.

RESUMO OBJETIVO Analisar a epidemia da covid-19 na região Nordeste do Brasil, uma das mais atingidas por essa virose. MÉTODOS Os dados oficiais para covid-19 dos estados do Nordeste são referentes ao período de março de 2020 a março de 2021. A análise para capitais e estados da série do acumulado semanal de casos e de óbitos confirmados foi feita com emprego do aplicativo JoinPoint Trend Analysis. RESULTADOS Em um ano, o Nordeste acumulou 22,9% dos casos e 21,5% dos óbitos do país pela covid-19. No início da pandemia, todos os estados apresentaram um crescimento sustentável de casos, primeiro nas capitais e depois interior. Em seguida, observam-se decréscimos em todos os estados e suas capitais, porém muitos permanecem com números elevados. Em meados do segundo semestre de 2020, o número de casos começa a crescer nos estados e suas capitais, alguns em velocidade explosiva, em especial no final de 2020 e início de 2021. Padrão similar é observado para os óbitos, os quais ultrapassaram ou aproximam-se do teto observado na primeira onda, na qual todas as capitais e estados do Nordeste adotaram intensas medidas de isolamento. Fortaleza, Recife e Teresina atingiram os maiores índices de isolamento de todas as capitais, perto de 0,60. Esse índice decresce, com tendência leve de crescimento até final de dezembro, voltando a decrescer. Com exceção de Fortaleza e Salvador, as demais capitais caíram para menos de 0,40. CONCLUSÃO O Nordeste brasileiro e o país estão em uma situação sanitária, social e econômica cada vez mais complexa. É necessário acelerar o processo de vacinação e manter as medidas não farmacológicas – constante uso de máscaras faciais, medidas de distanciamento e cuidados de higiene –, além de políticas de proteção aos trabalhadores que perderam as suas rendas e subsídios aos pequenos empresários.

ABSTRACT OBJECTIVE To analyze the epidemic of COVID-19 in northeastern Brazil, one of the regions most affected by the virus. METHODS The official data for COVID-19, from March 2020 to March 2021 in the states of the Northeast Region (NE), were used. The analysis of capital cities and states for accumulated weekly cases and confirmed deaths was made using the JoinPoint Trend Analysis application. RESULTS In one year, the Northeast region reported 22.9% of the cases and 21.5% of the deaths in the country due to COVID-19. At the beginning of the pandemic, all states showed a growing number of cases, first in the capitals and then in the interior. Following this wave, decreases are observed in all states and their capitals, but with many still reporting a large number of cases. In the middle of the 2nd semester of 2020 the number of cases begins to increase again simultaneously in states and their capitals—some at explosive speed—especially in late 2020 and early 2021. A similar pattern is observed in deaths, which exceed or approach the peak seen in the first wave. In the first wave, all capitals and northeastern states adopted intense isolation measures. Fortaleza, Recife and Teresina reached the highest isolation index of all capitals, close to 0.60. This index decreases, with a slight growth trend until the end of December. With the exception of Fortaleza and Salvador, the other capitals fell to less than 0.40. CONCLUSION The Brazilian NE and the country are in increasingly complicated health, social and economic situations. It is necessary to speed up vaccinations and maintain non-pharmacological measures: face masks, social distancing measures and hygiene care, in addition to policies to protect workers who have lost their incomes and to subsidize small business owners.

Resumo: O estudo buscou comparar as medidas antropométricas e proporções corporais de recém-nascidos do período pré-Zika com os nascidos durante a epidemia de microcefalia congênita pelo vírus Zika. Comparamos 958 recém-nascidos do período pré-Zika com 264 nascidos durante o período epidêmico. Foram classificados o perímetro cefálico, peso e comprimento dos neonatos de acordo com a escala de crescimento de Fenton & Kim. Consideramos desproporcionais aqueles neonatos que apresentaram microcefalia e peso ou comprimento adequado para sexo e idade gestacional, além daqueles cujo perímetros cefálicos eram menores que a razão ((comprimento / 2) + 9,5) -2,5cm. Estimamos as frequências de positividade para Zika e resultados de imagens de cerebrais entre bebês com microcefalia nascidos no período epidêmico, em relação aos parâmetros antropométricos e de proporcionalidade corporal. Baixo peso e microcefalia proporcional foram semelhantes entre recém-nascidos de ambos os períodos. Entretanto, as frequências de neonatos com microcefalia e com comprimento muito curto e microcefalia desproporcional foram muito maiores entre os nascidos no período epidêmico com anomalias cerebrais e positivos para Zika. Concluímos que a desproporção entre perímetro cefálico e comprimento ao nascer pode ser um indicador da gravidade da microcefalia causada pela síndrome congênita do Zika vírus.

Abstract: This study aimed to compare the anthropometric measurements and body proportionalities of neonates born before the Zika virus epidemic with those born during this period. We compared 958 neonates born during the pre-Zika epidemic with 264 neonates born during the epidemic period. The newborns had their head circumference, weight, and length classified according to the Fenton & Kim growth chart. We considered disproportionate those individuals that presented microcephaly and adequate weight or length for sex and gestational age, and those whose head circumferences were lower than the ratio ((length / 2) + 9.5) - 2.5cm. We estimated the frequencies of Zika positivity and brain imaging findings among neonates with microcephaly born during the epidemic period, concerning the anthropometric and body proportionality parameters. Low weight and proportionate microcephaly were similar among newborns from both periods. However, the frequencies of newborns with microcephaly with a very low length and disproportionate microcephaly were higher among the neonates of the epidemic period with brain abnormalities and positive for Zika virus. We conclude that, at birth, the disproportion between head circumference and length can be an indicator of the severity of microcephaly caused by congenital Zika.

Resumen: El objetivo del estudio fue comparar las medidas antropométricas y de proporcionalidad corporal en neonatos nacidos durante un período pre-Zika, con quienes nacieron durante la epidemia de microcefalia por el síndrome congénito Zika. Comparamos a 958 neonatos nacidos durante la epidemia pre-Zika, con 264 neonatos nacidos durante el período epidémico. A los recién nacidos se les clasificó su circunferencia de la cabeza, peso y longitud según la tabla de crecimiento Fenton & Kim. Consideramos desproporcionados a quienes presentaron microcefalia y peso o longitud adecuada para sexo y edad gestacional, y quienes tenían unas circunferencias de cabeza cuyo ratio era menor que ((longitud / 2) + 9.5) - 2.5cm. Estimamos las frecuencias de positividad para Zika, así como los resultados de imágenes cerebrales entre neonatos nacidos con microcefalia durante el período epidémico, en relación con parámetros antropométricos y de proporcionalidad corporal. Bajo peso y microcefalia proporcional fueron similares entre los recién nacidos de ambos períodos. No obstante, las frecuencias de recién nacidos con microcefalia con una longitud muy baja y microcefalia desproporcionada fueron mayores entre los neonatos del período epidémico, con anormalidades cerebrales y positivos para Zika. Concluimos que la desproporción entre la circunferencia de cabeza y longitud al nacer puede ser un indicador de la gravedad de la microcefalia, causada por el Zika congénito.

Resumo No Brasil, a pandemia da COVID-19 tem sido severa nos estados das regiões mais pobres, como o Nordeste. A falta de políticas nacionais para controle da pandemia levou as autoridades estaduais e municipais a implementarem medidas de saúde pública. O objetivo deste estudo é mostrar o efeito dessas medidas na epidemia. A maior incidência da COVID-19 entre os nove estados do Nordeste foi registrada em Sergipe, Paraíba e Ceará. O Piauí, a Paraíba e Ceará foram os que mais testaram. Muitos estados apresentavam alta proporção de pessoas em trabalho informal. Estados com aeroportos internacionais tiveram importante papel na entrada e disseminação inicial do vírus, em especial o Ceará. Todos os estados aplicaram medidas de distanciamento social, proibição de eventos públicos e fechamento de unidades de ensino. As respostas foram o aumento significativo de distanciamento social, em especial Ceará e Pernambuco, a queda do número de reprodução (Rt) e a separação da curva dos casos observados da curva dos casos esperados sem as intervenções não medicamentosas em todos os estados. A pobreza, a desigualdade e as altas taxas de trabalho informal fornecem pistas do porquê da intensidade da COVID-19 na região. Por outro lado, as medidas de mitigação tomadas precocemente pelos governantes amenizaram os efeitos da pandemia.

Abstract The COVID-19 pandemic has been most severe in the poorest regions of Brazil, such as the states of the Northeast Region. The lack of national policies for pandemic control forced state and municipal authorities to implement public health measures. The aim of this study is to show the effect of these measures on the epidemic. The highest incidence of COVID-19 among the nine states in the Northeast was recorded in Sergipe, Paraíba and Ceará. Piauí, Paraíba and Ceará were the states that most tested. Factors associated with transmission included the high proportion of people in informal work. States with international airports played an important role in the entry of the virus and the initial spread, especially Ceará. All states applied social distancing measures, banned public events and closed schools. The response was a significant increase in social distancing, especially in Ceará and Pernambuco, a decline in the reproduction rate (Rt), and a separation of the curve of observed cases versus expected cases if the non-pharmacological interventions had not been implemented in all states. Poverty, inequality, and the high rates of informal work provide clues to the intensity of COVID-19 in the region. On the other hand, the measures taken early by the governments mitigated the effects of the pandemic.

ABSTRACT Antiretroviral therapy (ART) has modified the outcome of patients with HIV infection, providing virological control and reducing mortality. However, there are several reasons as to why patients may discontinue their antiretroviral therapy, with adverse events being one of the main reasons reported in the literature. This is a case-control nested in a cohort of people living with HIV/AIDS, conducted to identify the incidence of ART modification due to adverse events and the associated factors, in two referral services in Recife, Brazil, between 2011 and 2014. Of the modifications occurred in the first year of ART, 25.7% were driven by adverse events. The median time elapsed between initiating ART and the first modification due to adverse events was 70.5 days (95% CI: 26-161 days). The main adverse events were dermatological, neuropsychiatric and gastrointestinal. Dermatological events were the earliest to appear after initiating ART. Efavirenz was the most prescribed and most modified drug during the study period. The group of participants who used zidovudine, lamivudine, and efavirenz had a 2-fold greater chance (adjusted OR: 2.16 95% CI: 1.28-3.65) of switching ART due to adverse events when compared to the group that used tenofovir with lamivudine and efavirenz.
