    Tetanus is an acute infectious disease, which in Brazil has a similar incidence between the sexes, although it is more frequently associated with males, due to greater exposure to trauma. This disease occurs due to the action of neurotoxins produced by Clostridium tetani, which have tropism for the cells of the Central Nervous System and act by blocking the neurotransmission and excitability of this system. This study aims to report a case from the Emergency Department of a hospital in Recife/PE. This is a 66-year-old patient, black, married, resident of a rural area, farmer, who comes to the service complaining of low back pain for 1 day, refractory to simple analgesics, anti-inflammatories and opioids. During medical evaluation, sialorrhea, intense sweating and generalized spastic movements begin. It then progresses to respiratory failure and cardiorespiratory arrest. Return to spontaneous circulation after 2 cycles and is medicated with IV Diazepam, due to the persistence of spastic movements and standard infections in wheezing. This is followed by orotracheal intubation and connection to a mechanical ventilator. After leaving the acute condition, family members told a story of perforating lesions on the knee 10 days before the symptoms appeared. The diagnosis of severe accidental tetanus is confirmed and anti-tetanus serum (SAT) or gamma globulin (IGAT) and dT vaccine are administered. Metronidazole, IV diazepam, continuous neuromuscular blockade and pump fentanyl are administered. Continue mechanical ventilation with a PEEP of 10 and transfer to the ICU. As this is a disease with a clinical diagnosis, but which has several differential diagnoses, early identification in the emergency room is a fundamental measure for this disease, as well as an appropriate treatment institution as soon as possible.O tétano é uma doença infecciosa aguda, que no Brasil possui uma incidência similar entre os sexos, embora seja mais frequentemente associada ao sexo masculino, devido a maior exposição a traumatismos. Essa doença ocorre pela ação de neurotoxinas produzidas pelo Clostridium tetani, que possuem tropismo pelas células do Sistema Nervoso Central e atuam bloqueando a neurotransmissão e a excitabilidade deste sistema. Este estudo visa relatar um caso do Departamento de Emergência de um hospital de Recife/PE. Trata-se de um  paciente de 66 anos, negro, casado, morador da zona rural, agricultor, que dá entrada no serviço com queixa de dor lombar há 1 dia, refratária a analgésicos simples, anti-inflamatórios e opioides. Durante a avaliação médica, inicia quadro de sialorreia, sudorese intensa e movimentos espásticos generalizados. Em seguida, evolui com insuficiência respiratória e parada cardiorrespiratória. Retorna à circulação espontânea após 2 ciclos e é medicado com Diazepam IV, devido à persistência dos movimentos espásticos e padrão respiratório em gasping. Segue-se com intubação orotraqueal e conexão ao ventilador mecânico. Após saída do quadro agudo, familiares relataram história de lesão perfurante em joelho há 10 dias do aparecimento dos sintomas. É fechado o diagnóstico de tétano acidental grave e como conduta, faz-se administração de soro antitetânico (SAT) ou gamaglobulina (IGAT) e vacina dT. Faz-se metronidazol, diazepam IV, bloqueador neuromuscular contínuo e fentanil em bomba. Mantém-se  a ventilação mecânica com uma PEEP de 10 e procede-se com transferência para UTI. Por se tratar de uma doença com diagnóstico clínico, mas que possui diversos diagnósticos diferenciais, a identificação precoce na emergência é uma medida fundamental para esta doença, assim como a instituição do tratamento adequado o mais breve possível

    Arboviruses are endemic diseases and pose a significant challenge to public health. Among these arboviruses is the Zika virus, which can be transmitted by the bite of the Aedes aegypti mosquito and also via the placental route. This study aimed to evaluate Zika virus cases in the state of Maranhão between 2018 and 2023. This retrospective, descriptive, and quantitative study is based on secondary data provided by the System of Notifiable Diseases (SINAN) from the Department of Informatics of the Unified Health System (DATASUS). The study assessed reported cases of Zika virus in the Maranhão population from 2018 to 2023. The total number of confirmed Zika virus cases in Maranhão during this period was 5,831. The municipality of São Luís had the highest number of cases (n=2,573). The age group with the highest frequency of ZIKV cases was 20 to 39 years, accounting for 28.62% (n=1,668) of the cases. Most individuals had completed high school, representing 29.70% of the cases. The most frequent ethnicity in the sample was mixed race (parda), corresponding to 77.06% (n=4,462) of the cases. The sample was predominantly composed of female individuals (57.16%). The majority of cases received laboratory confirmation (75.66%), with an outcome of recovery (80.64%) (n=4,702), and without the presence of pregnancy (93.16%). In light of these findings, it can be inferred that further studies on the prevalence of ZIKV in the Maranhão population are extremely relevant for the development of public policies for vector control.  As arboviroses são doenças endêmicas e constituem um grande desafio para saúde pública. Dentre as arboviroses, tem-se o zika vírus, que pode ser transmitido pela picada do mosquito Aedes Aegypti e também por via placentária.O presente estudo teve como objetivo avaliar os casos de zika vírus, no estado do Maranhão, entre os anos de 2018 e 2023. A amostra avaliada trata-se de um estudo retrospectivo, descritivo e quantitativo, com base em dados secundários disponibilizados através do Sistema de Notificação de Agravos (SINAN), no Departamento de Informática do Sistema Único de Saúde (DATASUS). O estudo avaliou os casos notificados de Zika vírus na população maranhense, entre 2018 e 2023. O total de casos confirmados de zika vírus, no Maranhão, entre 2018 e 2023, foi de 5831.O município de São Luís foi aquele que apresentou maiores números de casos (n=2573). A faixa etária com maior frequência de casos de ZIKV foi a de 20 a 39 anos, correspondendo a um percentual de 28,62% (n=1668) dos casos. Os indivíduos, em sua maioria, apresentavam ensino médio completo, correspondendo a 29,70%. A cor/ raça mais frequente, na amostra analisada, foi a parda correspondendo a 77,06% (n=4462) dos casos. A amostra foi composta majoritariamente por indivíduos do sexo feminino (57,16% ). A maioria dos casos recebeu confirmação laboratorial (75,66%), com evolução para cura (80,64%) (n=4702)  e sem a presença de gravidez, (93,16%). Diante do exposto pode-se inferir que o desenvolvimento de mais estudos acerca da prevalência do ZIKV na população maranhense é extremamente relevante para o desenvolvimento de políticas públicas de controle de vetores.&nbsp

    Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

    A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
