MPOX, o que sabemos sobre propagação e controle: uma revisão integrativa / MPOX, what we know about propagation and control: an integrative review / Viruela del mono, qué sabemos sobre la propagación y el control: una revisión integradora

Esta é uma revisão integrativa que busca compreender os fatores associados à propagação e controle de mpox, seguindo as recomendações estabelecidas pela declaração Preferred Reporting Items for Systematic Reviews and Meta-Analyses. A consulta foi feita nas bases de dados PubMed, Lilacs e Cochrane Library. Foram selecionados quinze artigos, com amostra majoritária de homens que fazem sexo sem proteção com homens e homens que viajaram para locais com surto da doença ou tiveram contato com pessoas infectadas. Os principais fatores associados à infecção e à propagação da doença foram históricos de viagem, sexo desprotegido, ingestão de carne possivelmente contaminada, aglomerados e contato próximo com pessoa sintomática. Quanto aos fatores relacionados à prevenção, estão principalmente associados à triagem de casos suspeitos, hábitos de higiene pessoal, uso de equipamentos de proteção individual e isolamento do doente.

This integrative review examines the factors associated with mpox spread and control, following the recommendations established by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Bibliographic search was conducted on the PubMed, Lilacs and Cochrane Library databases. The final sample included 15 articles, mostly composed of men who have unprotected sex with men and men who traveled to places with a mpox outbreak or had contact with infected people. Travel history, unprotected sex, eating potentially contaminated meat, crowding and close contact with a symptomatic person were the main factors associated with mpox infection and spread. Prevention is mainly associated with the screening of suspected cases, personal hygiene habits, use of personal protective equipment and patient isolation.

Los principales factores asociados con la infección y la propagación de la enfermedad fueron el historial de viajes, las relaciones sexuales sin protección, el consumo de carne potencialmente contaminada, el hacinamiento y el contacto cercano con una persona sintomática. Los factores relacionados con la prevención están asociados principalmente con el tamizaje de casos sospechosos, los hábitos de higiene personal, el uso de equipos de protección personal y el aislamiento del paciente.

Ocular manifestation of vertical transmission of dengue: case report / Manifestação ocular de transmissão vertical de dengue: relato de caso

ABSTRACT A 7-week-old male delivered by cesarean section presented with a positive serology for dengue along with preretinal and retinal hemorrhages, vitreous opacities and cotton wool spots. The patient and his mother had positive serologies for Non Structural Protein 1 (NS1) by ELISA. Retinal and vitreous findings improved over a sixteen-week period. Spectral domain optical coherence tomography (OCT) showed preserved macular architecture. In this case report, we suggest that retinal and vitreous changes may be the ocular presenting features of vertically transmitted dengue in newborns, and that those findings may resolve with no major structural sequelae.

RESUMO Neonato de 7 semanas, do sexo masculino, nascido de parto cesárea, apresentou sorologia positiva para dengue com hemorragias retinianas e pré-retinianas, opacidades vítreas e manchas algodonosas. O paciente e sua mãe haviam apresentado sorologias positivas para Non Structural Protein 1 através de ELISA. Achados na retina e no vítreo melhoraram em um período de dezesseis semanas. O exame de tomografia de coerência óptica de domínio espectral demonstrou arquitetura macular preservada. Neste relato de caso, sugerimos que alterações na retina e no vítreo podem ser os achados oculares aparentes em neonatos com infecção vertical por dengue, e que estes podem se resolver sem maiores sequelas estruturais.

Mpox: Aspectos epidemiológicos, imunopatogênicos e manejo pré e pós-infecção / Mpox: Epidemiological, immunopathogenic aspects and pre- and post-infection management

Mpoxou Varíola M é uma zoonose causada por vírus do gênero Orthopoxvirus, causadores também da varíola comum. É uma doença considerada rara e autolimitada, sendo endêmica em países africanos. Entretanto, no ano de 2022 ganhou destaque devido ao surto global que se iniciou, quando o mundo ainda se recuperava da pandemia da COVID-19. Dessa forma, por se tratar de uma doença emergente, a presente revisão visa pontuar aspectos gerais do que se sabe até o momento sobre a Mpox, desde sua imunopatogenia até as formas atuais de prevenção e cuidados pós-infecção

Mpox or Variola M is a zoonosis caused by viruses of the genus Orthopoxvirus, which also cause smallpox. It is a disease considered rare and self-limiting, being endemic in African countries. However, in 2022, it gained prominence due to the global outbreak that began when the world was still recovering from the COVID-19 pandemic. Thus, as it is an emerging disease, this review aims to point out general aspects of what is known so far about Mpox, from its immunopathogenesis to current forms of prevention and post-infection care

Caracterização e geoespacialização da sífilis gestacional e congênita no Paraná, Brasil, 2012-2020 / Characterization and geospacialization of gestational and congenital syphilis in Paraná, Brazil, 2012-2020 / Caracterización y geoespacialización de sífilis gestacional y congénita en Paraná, Brasil, 2012-2020

A sífilis persiste como um problema de saúde pública, sobretudo pelos entraves existentes no enfrentamento da sífilis gestacional e congênita. Considerando que a ocorrência dessas infecções se relaciona a fatores maternos e programáticos, este estudo buscou analisar as características epidemiológicas do binômio mãe-filho exposto à sífilis e sua distribuição espacial no Paraná entre 2012 e 2020. Trata-se de estudo descritivo e ecológico, com dados dos sistemas nacionais de informação do Brasil. Foram considerados os casos de gestantes e de crianças registrados entre 2012 e 2020 no estado do Paraná. Foram apresentadas as frequências absolutas e relativas para a caracterização, calculando-se a variação percentual entre o primeiro e o último triênio. Ainda, foi empregado o índice de Moran para a geoespacialização segundo regiões de saúde. Houve predomínio em mulheres de 20 a 39 anos (71,24%), brancas (67,22%) e com até oito anos de estudo (80,76%), com diagnóstico nas fases primária e latente (76,42%). Os casos concentraram-se em crianças do sexo masculino (48,72%), diagnosticadas na fase recente (96,42%), e naquelas cujas mães aderiram ao pré-natal (88,88%), mas os parceiros, por sua vez, não foram tratados (69,46%). Houve aumento do diagnóstico materno durante o pré-natal (16,61%) e redução dos óbitos infantis por sífilis (31,25%). Observou-se concentração das notificações nas regiões Metropolitana e de Pato Branco. Em suma, as gestantes apresentaram idade reprodutiva e baixa escolaridade e foram tratadas durante o pré-natal, contudo, sem a inclusão dos parceiros. Ademais, evidenciou-se comportamento espacial aleatório nas regiões de saúde, com disparidade entre a sífilis gestacional e a congênita.

Syphilis remains as serious public health issue due to existing obstacles in combating gestational and congenital syphilis. Since the onset of these infections is related to maternal and programmatic factors, this study analyzed the epidemiological profile of the mother-child binomial exposed to syphilis and its spatial distribution in Paraná from 2012 to 2020. This is a descriptive, ecological study with data from Brazilian national information systems. Cases of pregnant women and children recorded between 2012 and 2020 in the state of Paraná were considered. Absolute and relative frequencies were estimated for characterization, calculating the percentage variation between the first and last three years. The Moran index was also used for geospacialization according to health regions. Most women were aged 20 to 39 years (71.24%), white (67.22%), and had up to 8 years of schooling (80.76%), with diagnosis in the primary and latent stages (76.42%). Most cases concerned male children (48.72%), diagnosed in the recent phase (96.42%), and from mothers who adhered to prenatal care (88.88%), but the partners were untreated (69.46%). Maternal diagnosis increased during prenatal care (16.61%) and infant deaths by syphilis decreased (31.25%). Most cases were notified in the Metropolitan and Pato Branco regions. In short, the pregnant women were of reproductive age, had low education, and were treated during prenatal care, but their partners were not included. The health regions showed random spatial behavior, with disparity between gestational and congenital syphilis.

La sífilis persiste como un problema de salud pública, principalmente por los obstáculos en hacer frente la sífilis gestacional y congénita. Teniendo en cuenta que la ocurrencia de estas infecciones está relacionada con los factores maternos y programáticos, este estudio tuvo como objetivo analizar las características epidemiológicas del binomio madre-hijo expuestos a la sífilis y la distribución espacial en Paraná (Brasil) entre 2012 y 2020. Se trata de un estudio descriptivo y ecológico, con datos de los sistemas de información nacionales de Brasil. Se consideraron los casos de mujeres embarazadas y niños registrados entre 2012 y 2020 en Paraná. Se presentaron las frecuencias absolutas y relativas, calculando la variación porcentual entre el primer y el último trienio. Asimismo, se utilizó el índice de Moran, según regiones de salud. Predominaron las mujeres de entre 20 y 39 años de edad (71,24%), blancas (67,22%), con hasta ocho años de estudio (80,76%), con diagnóstico en estadio primario y latente (76,42%). Los casos se concentraron en hijos varones (48,72%), diagnosticados en fase reciente (96,42%), y en aquellos cuyas madres tuvieron acceso a los cuidados prenatales (88,88%), pero su pareja no recibió el tratamiento (69,46%). Hubo un aumento en el diagnóstico materno durante la atención prenatal (16,61%) y una reducción en las muertes de niños por sífilis (31,25%). Se observó una concentración de casos en las regiones Metropolitana y de Pato Branco. En resumen, las mujeres embarazadas se encontraban en edad reproductiva, tenían bajo nivel de estudios y eran atendidas durante el prenatal, sin incluir su pareja. Además, se evidenció un comportamiento espacial aleatorio en las regiones de salud, con disparidad entre sífilis gestacional y congénita.

Enfermedad de Hansen / Hansen's Disease

La lepra o enfermedad de Hansen es una infección crónica causada por Mycobacterium leprae (M. leprae) o Mycobacterium lepromatosis (M. lepromatosis), es una enfermedad infecciosa curable que es endémica en más de 140 países de todo el mundo. La Organización Mundial de la Salud lo declaró eliminado como un problema mundial de salud pública en el año 2000, sin embargo, en 2017 se informaron aproximadamente 200 000 casos nuevos en todo el mundo. A pesar de la terapia farmacológica combinada disponible, continúa como un importante problema de salud pública, que conlleva un fuerte estigma. En Cuba, según el Anuario Estadístico de Salud de 2020, se reportaron durante ese año 116 casos, las provincias más afectadas fueron Santiago de Cuba con 25 nuevos casos y Guantánamo con 17 nuevos casos. La presentación de caso se trata de una joven de 20 años, en edad reproductiva, con manifestaciones generales de astenia, pérdida del cabello, adenopatías, poliartritis, lesiones cutáneas y fiebre, que hizo sospechar en una enfermedad del colágeno. En estos momentos con buena evolución y en seguimiento por atención primaria de salud de su provincia(AU)

Leprosy or Hansen's disease is a chronic infection caused by mycobacterium leprae (M. leprae) or mycobacterium lepromatosis (M. lepromatosis). It is a curable infectious disease, endemic in more than 140 countries around the world. Despite being declared eradicated as a global public health problem by the World Health Organization in 2000, approximately 200,000 new cases were reported worldwide in 2017. Despite available combination drug therapy, it remains a major public health problem, carrying strong stigma. In Cuba, according to 2020 health statistical yearbook, 116 cases were reported during that year. The most affected provinces were Santiago de Cuba (25 new cases) and Guantánamo (17 new cases). The case to be reported concerns a 20-year-old young woman of reproductive age, with general manifestations of asthenia, hair loss, adenopathies, polyarthritis, skin lesions, and fever; she suspected was a collagen disease.

Lumbar puncture for neurosyphilis investigation in asymptomatic patients with HIV-syphilis coinfection: a cross-sectional study among infectious disease specialists

ABSTRACT BACKGROUND: Syphilis is a major public health issue worldwide. In people living with human immunodeficiency virus (PLHIV), there are higher incidences of both syphilis and neurosyphilis. The criteria for referring PLHIV with syphilis for lumbar puncture is controversial, and the diagnosis of neurosyphilis is challenging. OBJECTIVE: To describe the knowledge, attitudes, and practices of infectious disease specialists and residents in the context of care for asymptomatic HIV-syphilis coinfection using close-ended questions and case vignettes. DESIGN AND SETTING: Cross-sectional study conducted in three public health institutions in São Paulo (SP), Brazil. METHODS: In this cross-sectional study, we invited infectious disease specialists and residents at three academic healthcare institutions to answer a self-completion questionnaire available online or in paper form. RESULTS: Of 98 participants, only 23.5% provided answers that were in line with the current Brazilian recommendation. Most participants believed that the criteria for lumbar puncture should be extended for people living with HIV with low CD4+ cell counts (52.0%); in addition, participants also believed that late latent syphilis (29.6%) and Venereal Disease Research Laboratory (VDRL) titers ≥ 1:32 (22.4%) should be conditions for lumbar puncture in PLHIV with no neurologic symptoms. CONCLUSION: This study highlights heterogeneities in the clinical management of HIV-syphilis coinfection. Most infectious disease specialists still consider syphilis stage, VDRL titers and CD4+ cell counts as important parameters when deciding which patients need lumbar puncture for investigating neurosyphilis.

The crucial role of the partner in the incidence of cases of congenital syphilis in the state of Sergipe: an analysis in 17 years / O papel crucial do parceiro na incidência dos casos de sífilis congênita no estado de Sergipe: uma análise em 17 anos

Introduction: Congenital syphilis is a highly preventable infectious disease. The relevance of the partner in the transmission of the disease is undeniable, and the underestimation of its treatment is a great risk with serious fetal consequences. Objective: The aim of this study was to analyze the partner's contribution to the inadequate treatment of pregnant women and the incidence of cases of congenital syphilis in Sergipe between 2005 and 2022. Methods: A cross-sectional, retrospective, and descriptive study was carried out through the collection of reported cases of congenital syphilis from the Notifiable Diseases Information System (SINAN). Results: There was a considerable increase in the number of reported cases of congenital syphilis in Sergipe in the past 17 years, with a predominance of untreated partners (61.5%) over treated ones (14.9%), excluding the 23.6% who had this information ignored. The variations presented from 2018 onwards stand out, resulting from the softening implemented in the notification of partner data, with an average of 23.7% of ignored information. Consequently, the diagnosis of recent congenital syphilis was found in 83.7% of newborns whose parents were not treated, in addition to 50% of cases of late infection and the vast majority of cases of stillbirths/abortion (92.6%) and deaths from the disease (78.8%). Furthermore, the non-inclusion of the partner in prenatal care (83%) contributed mainly to delays in the diagnosis of maternal syphilis, with 90.1% during delivery/curettage, 76.7% after delivery, and 77.2% of them not even identified with the disease. Conclusion: In addition to the increase in cases of congenital syphilis, there was a predominance of untreated partners, coinciding with changes in the notification criteria in 2018, which contributed to most cases of delay in maternal diagnosis, reinfection, and vertical transmission. Thus, the partner's approach is essential to guarantee the treatment and interruption of the transmission of the disease

Introdução: A sífilis congênita é uma doença infectocontagiosa altamente prevenível. A relevância do parceiro na transmissão da doença é inegável, sendo a subestimação do seu tratamento um grande risco, com graves consequências fetais. Objetivo: Analisar a contribuição do parceiro na inadequação do tratamento da gestante e na incidência dos casos de sífilis congênita em Sergipe entre 2005 e 2022. Métodos: Realizou-se um estudo transversal, retrospectivo e descritivo, através da coleta de casos notificados de sífilis congênita do Sistema de Informação de Agravos de Notificação (SINAN). Resultados: Observou-se um aumento considerável do número de casos notificados de sífilis congênita em Sergipe nos últimos 17 anos, com o predomínio de parceiros não tratados (61,5%) em relação aos tratados (14,9%), descontando-se os 23,6% que tiveram essa informação ignorada. Destacam-se as variações apresentadas a partir de 2018, decorrentes da amenização implementada na notificação dos dados do parceiro, com uma média de 23,7% de informações ignoradas. Consequentemente, o diagnóstico de sífilis congênita recente foi encontrado em 83,7% dos recém-nascidos cujos pais não foram tratados, além de 50% dos casos de infecção tardia e a maioria dos casos de natimortos/aborto (92,6%) e óbitos pelo agravo (78,8%). Outrossim, a não inclusão do parceiro na assistência pré-natal (83%) contribuiu majoritariamente nos atrasos no diagnóstico da sífilis materna, sendo 90,1% no parto/curetagem, 76,7% após o parto, além de 77,2% delas que nem mesmo foram identificadas com a doença. Conclusão: Além do aumento de casos de sífilis congênita, houve predomínio de parceiros não tratados, coincidindo com as mudanças nos critérios de notificação em 2018, o que contribuiu para a maioria dos casos de atraso no diagnóstico materno, reinfecção e transmissão vertical. Assim, a abordagem do parceiro é imprescindível para garantia do tratamento e da interrupção da transmissão da doença

Advances in mosquito repellents / 药学实践杂志

Mosquitoes are the biological vectors of many diseases. Mosquito-borne infectious diseases are serious public health problems in tropical areas. With the increasing resistance of mosquitoes to insecticides, it becomes difficult to control mosquito-borne infectious diseases. The application of mosquito repellents can not only control the spread of mosquito-borne infectious diseases to a certain extent, but also reduce the use of insecticides and relieve the environmental pressure. This paper introduces and summarizes the research progresses of new mosquito repellents in recent years to provide reference resource for the further development of mosquito repellents.

Cellular nanovesicles for therapeutic immunomodulation: A perspective on engineering strategies and new advances

Cellular nanovesicles which are referred to as cell-derived, nanosized lipid bilayer structures, have emerged as a promising platform for regulating immune responses. Owing to their outstanding advantages such as high biocompatibility, prominent structural stability, and high loading capacity, cellular nanovesicles are suitable for delivering various immunomodulatory molecules, such as small molecules, nucleic acids, peptides, and proteins. Immunomodulation induced by cellular nanovesicles has been exploited to modulate immune cell behaviors, which is considered as a novel cell-free immunotherapeutic strategy for the prevention and treatment of diverse diseases. Here we review emerging concepts and new advances in leveraging cellular nanovesicles to activate or suppress immune responses, with the aim to explicate their applications for immunomodulation. We overview the general considerations and principles for the design of engineered cellular nanovesicles with tailored immunomodulatory activities. We also discuss new advances in engineering cellular nanovesicles as immunotherapies for treating major diseases.

OBJECTIVE@#To analyze the global epidemic status of the Ebola virus disease (EVD) and assess the importation risk into China.@*METHODS@#Data from World Health Organization reports were used. We described the global epidemic status of EVD from 1976-2021, and assessed and ranked the importation risk of EVD from the disease-outbreaking countries into China using the risk matrix and Borda count methods, respectively.@*RESULTS@#From 1976-2021, EVD mainly occurred in western and central Africa, with the highest cumulative number of cases (14,124 cases) in Sierra Leone, and the highest cumulative fatality rate (85%) in the Congo. Outbreaks of EVD have occurred in the Democratic Republic of the Congo and Guinea since 2018. The importation risk into China varies across countries with outbreaks of disease. The Democratic Republic of the Congo had an extremely high risk (23 Borda points), followed by Guinea and Liberia. Countries with a moderate importation risk were Nigeria, Uganda, Congo, Sierra Leone, Mali, and Gabon, while countries with a low importation risk included Sudan, Senegal, and Co

Evaluating elimination of mother-to-child transmission of HIV in Suriname: a mixed method study / Estudio con métodos mixtos para evaluar la eliminación de la transmisión maternoinfantil del VIH en Suriname / Avaliação da eliminação da transmissão materno-infantil do HIV no Suriname: estudo de métodos mistos

ABSTRACT Objectives. To evaluate the cascade of care for the elimination of mother-to-child-transmission of human immunodeficiency virus (HIV) in Suriname and identify sociodemographic and clinical factors preventing transmission to exposed infants. Methods. A mixed-methods study design was used. Antenatal care data from the 2018 cross-sectional multi-indicator cluster survey on 1 026 women aged 15-49 years who had had a live birth in the previous 2 years were used. Furthermore, national data on a cohort of 279 mothers with HIV and their 317 infants born from 2016 to 2018 were evaluated. Additionally, 13 cases of mother-to-child-transmission of HIV were reviewed. Results. In 89.3% of cases, no mother-to-child HIV transmission occurred. Early cascade steps show that 28.4% of women had unmet family planning needs, 15% had no antenatal visits, 8% delivered outside a health facility, and 71.5% received an HIV test during antenatal care. Of the pregnant women with HIV, 84.2% received antiretroviral therapy, while 95.5% of their infants received HIV prophylactic treatment. Receiving antiretroviral therapy for the mother (odds ratio (OR) 45.4, 95% confidence interval (CI) 9.6-215.3) and the child (OR 145.7, 95% CI 14.4-1477.4) significantly increased the odds of a negative HIV test result in infants. Conversely, living in the interior decreased the odds (OR 0.2, 95% CI 0.4-0.7) compared with urban living. Conclusions. HIV medication for mothers with HIV and their infants remains key in the prevention of mother-to-child-transmission of HIV. Early prenatal care with follow-up should be strengthened in Suriname.

RESUMEN Objetivos. Evaluar la secuencia de la atención para la eliminación de la transmisión maternoinfantil del virus de la inmunodeficiencia humana (VIH) en Suriname y determinar los factores sociodemográficos y clínicos que previenen la transmisión a lactantes expuestos al virus. Métodos. En este estudio se empleó un diseño de métodos mixtos. Se utilizaron los datos de atención prenatal procedentes de la encuesta transversal de indicadores múltiples por conglomerados del 2018, realizada en 1 026 mujeres de entre 15 y 49 años que habían dado a luz a un nacido vivo en los dos años anteriores. También se evaluaron los datos nacionales correspondientes a una cohorte de 279 madres con infección por el VIH y sus 317 bebés nacidos entre el 2016 y el 2018. Además, se analizaron en detalle 13 casos de transmisión maternoinfantil del VIH. Resultados. En el 89,3% de los casos no hubo transmisión maternoinfantil del VIH. En las etapas iniciales de la secuencia de la atención se observó que el 28,4% de las mujeres no tenían cubiertas sus necesidades de planificación familiar; además, el 15% no dispusieron de consultas de atención prenatal, el 8% dieron a luz fuera de un centro de salud y en el 71,5% se llevó a cabo una prueba de detección del VIH en el marco de la atención prenatal. De las mujeres embarazadas con infección por el VIH, el 84,2% recibió un tratamiento antirretroviral, mientras que el 95,5% de los bebés recibieron un tratamiento profiláctico contra el VIH. La administración de tratamiento antirretroviral a la madre (cociente de posibilidades [OR] = 45,4; intervalo de confianza [IC] del 95%: 9,6-215,3) y al bebé (OR = 145,7; IC del 95%: 14,4-1477,4) hizo que aumentaran significativamente las posibilidades de obtener un resultado negativo en la prueba de detección del VIH en los lactantes. Por el contrario, residir en el interior del país hizo que disminuyeran dichas posibilidades (OR = 0,2; IC del 95%: 0,4-0,7), en comparación con residir en un entorno urbano. Conclusiones. Para las madres con infección por el VIH y para sus bebés, los medicamentos contra el VIH siguen siendo esenciales para prevenir la transmisión maternoinfantil del VIH. En Suriname debe reforzarse la atención prenatal temprana, incluido el seguimiento.

RESUMO Objetivos. Avaliar a cascata de atendimento para a eliminação da transmissão materno-infantil do vírus da imunodeficiência humana (HIV) no Suriname e identificar fatores sociodemográficos e clínicos que impedem a transmissão a bebês expostos. Métodos. Foi utilizado um delineamento de estudo com métodos mistos. Foram usados dados de atendimento pré-natal de uma pesquisa de indicadores múltiplos por conglomerados de corte transversal realizada em 2018, que incluiu 1 026 mulheres com idades entre 15 e 49 anos que haviam tido um nascido vivo nos dois anos anteriores. Além disso, foram avaliados os dados nacionais de uma coorte de 279 mães com HIV e seus 317 bebês nascidos vivos de 2016 a 2018, além de 13 casos de transmissão materno-infantil de HIV. Resultados. Em 89,3% dos casos, não houve transmissão materno-infantil do HIV. As etapas iniciais da cascata demonstram que 28,4% das mulheres tiveram necessidades não atendidas de planejamento familiar, 15% não fizeram consultas pré-natais, 8% tiveram o parto fora de uma unidade de saúde e 71,5% receberam um teste de HIV durante o atendimento pré-natal. Das gestantes com HIV, 84,2% receberam terapia antirretroviral, e 95,5% de seus bebês receberam tratamento profilático para o HIV. O tratamento antirretroviral da mãe (razão de chances [RC]: 45,4; intervalo de confiança [IC] de 95%: 9,6-215,3) e da criança (RC: 145,7; IC 95%: 14,4-1477,4) aumentou significativamente a probabilidade de um resultado negativo no teste de HIV dos bebês. Por outro lado, morar no interior diminuiu a probabilidade (RC: 0,2; IC 95%: 0,4-0,7) em comparação com o ambiente urbano. Conclusões. A medicação de mães e bebês contra o HIV continua sendo fundamental para a prevenção da transmissão materno-infantil do HIV. Deve-se reforçar o atendimento pré-natal precoce com acompanhamento no Suriname.

Clinical and serological findings in pregnant women and newborns: patterns of coronavirus disease 2019 placental histopathology

SUMMARY OBJECTIVE: The objective of this study was to evaluate the correlation between clinical and serological findings of pregnant women and newborns with patterns of histopathologic changes of the placenta diagnosed with coronavirus disease 2019. METHODS: A prospective descriptive study was conducted with pregnant women who were positive for SARS-CoV-2 by reverse transcription polymerase chain reaction or serology (IgG and IgM). Clinical analyses were performed using ELISA to detect anti-SARS-CoV-2 IgG and IgA antibodies using the S1 spike protein domain with the Euroimmun kit. Histopathologic analyses of placentas were performed by two expert pathologists. RESULTS: Maternal SARS-CoV-2 infection was associated with increased neonatal hospital length of stay (p=0.03), increased preterm birth (p=0.04), and Apgar score<7 at 1st min (p=0.00) and 5th min (p=0.02). Pregnant women with positive IgG and/or IgA at delivery had a higher incidence of placental histopathologic changes in addition to a greater likelihood of having an IgG-positive fetus (p<0.0001). Placentas with positive reverse transcription polymerase chain reaction for SARS-CoV-2 had a higher incidence of histopathologic changes such as maternal vascular hypoperfusion changes (p=0.00). CONCLUSION: Maternal SARS-CoV-2 infection was associated with adverse perinatal outcomes. Pregnant women with positive IgG at delivery had a higher incidence of placental histopathologic changes. Placentas with positive reverse transcription polymerase chain reaction for SARS-CoV-2 had a higher incidence of histopathologic changes such as maternal vascular hypoperfusion.

Current morbimortality and one-year survival after pneumonectomy for infectious diseases

Abstract Objective: Identify the one-year survival rate and major complications in patients submitted to pneumonectomy for infectious disease. Methods: Retrospective data from all cases of infectious disease pneumonectomy over the past 10 years were collected from two reference centers. The authors analyzed: patient demographics, etiology, laterality, bronchial stump treatment, presence of previous pulmonary resection, postoperative complications in the first 30 days, the treatment used in pleural complications, and one-year survival rate. Results: 56 procedures were performed. The average age was 44 years, with female predominance (55%). 29 cases were operated on the left side (51%) and the most frequent etiology was post-tuberculosis (51.8%). The overall incidence of complications was 28.6% and the most common was empyema (19.2%). Among empyema cases, 36.3% required pleurostomy, 27.3% required pleuroscopy and 36.3% underwent thoracoplasty for treatment. Bronchial stump fistula was observed in 10.7% of cases. From all cases, 16.1% were completion pneumonectomies and 62.5% of these had some complication, a significantly higher incidence than patients without previous surgery (p = 0.0187). 30-day in-hospital mortality was (7.1%) with 52 cases (92.9%) and 1-year survival. The causes of death were massive postoperative bleeding (1 case) and sepsis (3 cases). Conclusions: Pneumonectomy for benign disease is a high-risk procedure performed for a variety of indications. While morbidity is often significant, once the perioperative risk has passed, the one-year survival rate can be very satisfying in selected patients with benign disease.

Screening for coronavirus disease 2019 in pregnant women admitted for delivery: an observational study

SUMMARY OBJECTIVE: The aim of this study was to examine the impact of symptom-based screening on the prevalence and outcomes of neonatal coronavirus disease 2019 in pregnant women admitted for delivery. METHODS: A retrospective observational study was conducted from June to August 2020 at Gonzaga Mota of Messejana Hospital, Fortaleza, CE, Brazil. All pregnant women were screened for coronavirus disease 2019 based on symptoms. Reverse transcription-polymerase chain reaction or immunology assays for severe acute respiratory syndrome coronavirus 2 were performed when a patient reported a symptom. All newborns of symptomatic patients were submitted for Reverse transcription-polymerase chain reaction. Newborns were divided into groups according to the Reverse transcription-polymerase chain reaction results to identify the relationship between maternal symptoms and neonatal coronavirus disease 2019. RESULTS: A total of 55 (55/1,026, 5.4%) and 50 (50/1,026, 4.8%) pregnant women reported symptoms and had a positive confirmatory test, respectively. The most common symptom of coronavirus disease 2019 among the pregnant women with positive confirmatory test was cough (n=23, 46%). Seven newborns (7/50, 14%) of symptomatic mothers had positive Reverse transcription-polymerase chain reaction. Upon birth, no newborn had serious complications. CONCLUSION: Universal screening of pregnant women admitted for delivery can reduce the perinatal transmission of coronavirus disease 2019. Symptom-based screening can be an alternative for regions with a low prevalence of the disease where a better allocation of financial resources is necessary.

Factors associated with COVID-19 fatality among patients admitted in Mashonaland West Province, Zimbabwe 2020-2022: a secondary data analysis

Introduction: approximately 15% of COVID-19 patients develop symptoms necessitating admission. From 2020 to 2022, Mashonaland West Province had an institutional case fatality rate of 23% against a national rate of 7%. Therefore, we evaluated the COVID-19 admissions in the province to determine the factors associated with COVID-19 mortality. Methods: we conducted an analytical cross-sectional study based on secondary data from isolation centers across the province using all 672 death audit forms and patient records. We obtained data on patient demographics, signs and symptoms, clinical management and oxygen therapy administered, among other things. Data were entered into an electronic form and imported into Epi-info 7 for analysis bivariate and multivariate was conducted. Results: we found that being an older man, aOR 1.04 (1.03-1.05), who had diabetes aOR 6.0 (95% CI: 3.8-9.2) and hypertension aOR 4.5 (95% CI: 2.8-6.5) were independent risk factors. Patients put on dexamethasone aOR 2.4 (95% CI: 1.6-3.4) and heparin/clexane aOR 1.6 (95% CI: 1.1-2.2) had a higher mortality risk. However, vitamin C aOR 0.48 (95% CI: 0.31-0.71) and oxygen therapy aOR 0.14 (95% CI: 0.10-0.19) and being pregnant aOR 0.06 (95% CI: 0.02-0.14) were protective. Conclusion: mortality risk increased in older male patients with comorbidities and with those on dexamethasone and heparin therapy. Oxygen therapy and vitamin C were protective. There is a need to conduct further study of the source of these variations in risk across patients to establish the true impact of differences in individuals' mortality.

The study was undertaken from September 2018 to April 2019 to determine the prevalence of cutaneous leishmaniasis in human beings living in six districts of Karachi. Suspected persons were screened for the disease and positive cases were identified on the basis of skin lesions and blood samples. Samples were observed by mounting their smear. A total of 207 subjects of different ages and sex groups were investigated, however, only 192 (92%) of the suspected cases were found to have the disease 64% of cases were male which were significantly high (p<0.05), than female 36%. The lesion was more frequently detected among the youth ages of 21-30 years (31%) as compared to other groups. In both sexes, legs were found to be more infected (25% male + 20% female) followed by arms (20% male + 0% female) and face (15% male +11% female). The mixed body parts had shown the lowest infections such as (4% in males + 5%) in females. In conclusion, the highest and lowest leishmaniasis infections were observed in District West (23% male + 9% female) followed by District East (15% male + 7% female), District Malir (11% male+ 4% female), District Central (7% male + 5% female), District Korangi (4% male + 7% female) and District South (4% male + 4% female) respectively.
