The role of the adrenalectomy in the management of pheochromocytoma: the experience of a Portuguese referral center.

PURPOSE: Pheochromocytoma is a rare neuroendocrine tumor. Despite the low incidence, these tumors are of indisputable importance. This study aimed to analyze the management of pheochromocytoma in a referral center, with an emphasis on the minimally invasive adrenalectomy, which is the preferred therapeutic approach. METHODS: A retrospective analysis was performed on a cohort of patients diagnosed with pheochromocytoma who underwent adrenalectomy between January 2013 and December 2022. Clinical data including demographics, timelines, symptomatology, comorbidities, biochemical markers, genetic testing, surgical details, and follow-up outcomes, were collected and analyzed. RESULTS: The cohort included 44 patients, predominantly women (52.27%), with a median age of 53.39 years (range 13-83). Most of patients exhibited paroxysmal symptoms suggesting catecholamine excess. Documented hypertension was the most frequent (86.36%), along with glucose anomalies (40.01%) and anxiety disorder (31.82%). Genetic testing was performed in 36 (81.81%) patients and 14 (38.88%) revealed a positive result, predominantly RET pathogenic variant. Laparoscopic surgery was performed in 34 (79.07%) patients, showing significantly shorter operative time (2.5 h vs. 4.25 h, t-test p < 0,001) and fewer complications (23.53% vs 77.78%, p = 0.008). Postoperative complications occurred in 36.36% of the patients, mostly mild (grade I, 56.25%), with no mortality. SDHB pathogenic variant correlated with both recurrent and metastatic disease (p = 0.006). One-year follow-up reported 9.09% recurrence and 6.82% metastasis. CONCLUSIONS: Adrenalectomy demonstrated a high safety and effectiveness. This study exhibited a higher rate of genetic testing referral than other studies. Despite past advances, there is still a need for further studies to establish protocols and evaluate new techniques.

Colorectal cancer screening: A review of current knowledge and progress in research.

Colorectal cancer (CRC) is one of the most prevalent malignancies worldwide, being the third most commonly diagnosed malignancy and the second leading cause of cancer-related deaths globally. Despite the progress in screening, early diagnosis, and treatment, approximately 20%-25% of CRC patients still present with metastatic disease at the time of their initial diagnosis. Furthermore, the burden of disease is still expected to increase, especially in individuals younger than 50 years old, among whom early-onset CRC incidence has been increasing. Screening and early detection are pivotal to improve CRC-related outcomes. It is well established that CRC screening not only reduces incidence, but also decreases deaths from CRC. Diverse screening strategies have proven effective in decreasing both CRC incidence and mortality, though variations in efficacy have been reported across the literature. However, uncertainties persist regarding the optimal screening method, age intervals and periodicity. Moreover, adherence to CRC screening remains globally low. In recent years, emerging technologies, notably artificial intelligence, and non-invasive biomarkers, have been developed to overcome these barriers. However, controversy exists over the actual impact of some of the new discoveries on CRC-related outcomes and how to effectively integrate them into daily practice. In this review, we aim to cover the current evidence surrounding CRC screening. We will further critically assess novel approaches under investigation, in an effort to differentiate promising innovations from mere novelties.

The lucky polyp: an unusual manifestation of chronic schistosomiasis.

A 23-year-old male from Brazil presented with bright red hematochezia. Proctological examination revealed grade II internal hemorrhoids, but flexible sigmoidoscopy uncovered a 6 mm-pedunculated polyp in the sigmoid colon, which was found to result from inflammatory reaction to Schistosoma mansoni egg deposition. The patient had no signs of portal hypertension and was successfully treated with praziquantel. This case underscores a rare presentation of chronic intestinal schistosomiasis and emphasizes the role of early diagnosis in preventing severe hepatic sequelae of chronic Schistosoma infection.

Severe Acute Liver Injury due to Secondary Hemophagocytic Lymphohistiocytosis: A Case Report.

Severe acute liver injury (ALI) is mostly triggered by viral infections and hepatotoxic drugs; however, it can also be seen in systemic diseases. Hemophagocytic lymphohistiocytosis (HLH) is a rare, immune-mediated syndrome that presents as a life-threatening inflammatory disorder affecting multiple organs. Secondary causes occur mainly in the set of malignancy, infection, and autoimmune disease, and are seldom triggered by vaccination. Although liver involvement is common, presentation as severe ALI is rare. We describe a case of a 65-year-old male with history of low-risk chronic lymphocytic leukemia and rheumatoid arthritis treated with prednisolone who presented with persistent fever and jaundice 1 week after COVID-19 vaccination. The diagnosis was challenging given the predominant liver impairment, characterized by hyperbilirubinemia, transaminases over 1,000 U/L, and prolonged INR, which prompted an extensive investigation and exclusion of autoimmune, toxic, and viral causes of hepatitis. Laboratory workup revealed bicytopenia, hyperferritinemia, which together with organ failure and evidence of hemophagocytosis in bone marrow suggested the diagnosis of HLH. After excluding infectious etiologies, flare of rheumatological disease, and the progression of hematological disease, HLH was diagnosed. He was successfully treated with etoposide and corticosteroids, with dramatic improvement of liver tests. After exclusion of other causes of secondary HLH, the recent vaccination for COVID-19 was the likely trigger. We report a case of double rarity of HLH, as it presented with severe liver dysfunction which was probably triggered by vaccination. In this case, the predominant liver involvement urged extensive investigation of liver disease, so a high index of suspicion was required to make an early diagnosis. Clinicians should consider HLH in patients with unexplained signs and symptoms of systemic inflammatory response and multiorgan involvement, including severe liver involvement as the first presentation.

A lesão hepática aguda (LHA) grave é desencadeada principalmente por infeções virais e hepatotóxicos; contudo, pode ocorrer em condições com envolvimento sistémico. A linfohistiocitose hemofagocítica (LHH) é uma síndrome inflamatória, rara, imunomediada, potencialmente fatal, que pode afetar múltiplos órgãos. A LHH secundária ocorre em contexto de neoplasias, infeções e doenças autoimunes, podendo raramente ser precipitada pela vacinação. Embora seja frequente o envolvimento hepático na LHH, a apresentação como LHA grave é rara. Os autores descrevem o caso de um homem de 65 anos com história de leucemia linfocítica crónica de baixo risco e artrite reumatóide sob prednisolona de 65 anos, que se apresentou com febre persistente e icterícia uma semana após a primeira dose da vacina COVID-19. O diagnóstico constituiu um desafio dado o envolvimento hepático predominante, caracterizado por hiperbilirrubinemia, transaminases acima de 1000 U/L e INR prolongado, o que condicionou uma extensa investigação e exclusão das causas autoimunes, tóxicas, e virais de doença hepática. A presença de bicitopenia e hiperferritinemia, conjuntamente com o desenvolvimento de falências de órgão e evidência de hemofagocitose na medula óssea sugeriram o diagnóstico de LHH. Após exclusão infeções, agudização da doença reumatológica e progressão da doença hematológica, foi feito o diagnóstico de LHH.O doente foi tratado com etoposido e corticosteróides com sucesso, verificando-se uma melhoria dramática das provas hepáticas. Após a exclusão de outras causas de LHH secundária, a recente vacinação foi assumida como provável fator desencadeante. Relatamos um caso raro de LHH, quer pela apresentação com lesão hepática grave, quer pela vacinação como presumível desencadeante. Neste caso, o envolvimento hepático predominante promoveu a uma investigação extensa da doença hepática, tendo sido necessário um elevado índice de suspeição para um diagnóstico atempado. Os médicos devem considerar o diagnóstico de LHH em doentes com sinais e sintomas de resposta inflamatória sistémica, inexplicados que se acompanham por disfunção multiorgânica, nomeadamente disfunção hepática grave como apresentação clínica.

Curae de mim ­ A Prática Especializada de Enfermagem de Saúde Mental e Psiquiátrica na Intervenção com Cuidadores Familiares / Curae from me - The Specialised Practice of Mental Health and Psychiatric Nursing in Intervention with Family Caregivers

Cuidar é viver em função de quem é cuidado, é dirigir toda a atenção, entrega e dedicação a outro que depende de si. A vida do cuidador familiar passa a organizar-se em função do cuidado ao outro, em função do bem-estar do outro. Ser cuidador familiar de uma pessoa com doença de Alzheimer está associado a sobrecarga na prestação de cuidados, bem como ao risco de doença mental. As pessoas com doença de Alzheimer necessitam de cuidados a longo prazo, requerendo dos seus cuidadores familiares uma dedicação e cuidado também a longo prazo. O Enfermeiro Especialista em Enfermagem de Saúde Mental e Psiquiátrica pode ter um papel determinante no acompanhamento dos cuidadores familiares, nomeadamente na capacitação para o desenvolvimento de estratégias de gestão da sobrecarga e de promoção de saúde mental. O presente relatório inclui o exercício de análise reflexiva do processo de aquisição de competências de Enfermeira Especialista em Enfermagem de Saúde Mental e Psiquiátrica, mas também o processo de confirmação das competências comuns de Enfermeiro Especialista. O relatório reflete um percurso pautado por uma prática baseada na evidência, alicerçada em modelos de enfermagem, que se traduziu no desenvolvimento de intervenções especializadas em contexto de um Serviço de Internamento de Psiquiatria, de uma Unidade de Cuidados na Comunidade e de uma Equipa Comunitária. A prática especializada, nos diferentes contextos, decorreu da identificação das necessidades encontradas, do planeamento e da implementação, com base nos Padrões de Qualidade dos Cuidados de Enfermagem de Saúde Mental, e com o propósito de ganhos em saúde mental na pessoa/grupos/comunidade.

High correlation between binding IgG (anti-RBD/S) and neutralizing antibodies against SARS-CoV-2 six months after vaccination

Vaccination is considered the most important measure to control the COVID-19 pandemic. Extensive follow-up studies with distinct vaccines and populations are able to promote robust and reliable data to better understand the effectiveness of this pharmacologic strategy. In this sense, we present data regarding binding and neutralizing antibodies throughout time, from vaccinated and previously infected (PI) health care workers (HCW) in Portugal. We analyzed serum samples of 132 HCW, vaccinated and with previous SARS-CoV-2 infection. Samples were collected before vaccination (baseline, M1), at second dose vaccine uptake (M2), and 25-70 days (M3) and 150-210 days (M4) after the second dose for vaccinated individuals. The IgG (anti-RBD/S) antibody geometric mean titer found on vaccinated HCW at M2 (814.7 AU/ml; 95% CI 649.8-1021.5) were significantly higher than those found on PI HCW at recruitment (M1) (252.6 AU/ml; 95% CI 108.7 - 587.1), and the neutralizing antibodies (nAb) were similar between these groups, 93.2 UI/ml (95% CI 73.2-118.5) vs. 84.1 UI/ml (95% CI 40.4-155.9), respectively. We detected about 10-fold higher IgG (anti-RBD/S) antibodies titers in M3 when compared with M2, with a slightly but significant decrease in titers from 36 days after the second dose vaccine uptake. The increase of nAb titers were correlated with IgG (anti-RBD/S) antibodies titers, however, contrasting to IgG (anti-RBD/S) antibodies titers, we did not detect a decrease in nAb titer from 36 days after a second vaccine dose uptake. At M4, was observed a decrease of 8-fold in binding IgG (anti-RBD/S) and nAb. No significant differences in antibody titers were observed by sex, age or chronic diseases. Our results suggest that IgG (anti-RBD/S) antibodies titers and nAb titers could be correlated, but ongoing follow up of the cohort, is required to better understand this correlation, and the duration of the immune response.

IL-2 and IFN- are biomarkers of SARS-CoV-2 specific cellular response in whole blood stimulation assays

A proper description of the immune response to SARS-CoV-2 will be critical for the assessment of protection elicited after both infection and vaccination. Uncoupled T and B cell responses have been described in acute and convalescent patients and exposed individuals. We assessed the potential usefulness of whole blood stimulation assays to identify functional cellular immune responses to SARS-CoV-2. Blood from COVID-19 recovered individuals (5 months after infection) and negative subjects was stimulated for 24 hours with HLA predicted peptide "megapools" of the Spike and Nucleoprotein, or the mixture of them. After stimulation, cytokines were quantified using a beads-based multiplex assay. Interleukin-2 and IFN-{gamma} were found to be specific biomarkers of SARS-CoV-2 cellular response. Using the Spike and Nucleoprotein mixture, 91.3% of COVID-19 recovered individuals presented an IL-2 stimulation index over the cut-off, while 82.6% showed IFN-{gamma}. All the negative individuals presented an IL-2 response under the cut-off, while 5.3% of these subjects presented positive IFN-{gamma} stimulation indexes. Moreover, IL-2 production correlated with IgG levels for Spike 1, RBD, and Nucleocapsid. In conclusion, we demonstrate the potential of whole blood stimulation assays and the quantification of IL-2 and IFN-{gamma} for the analysis of SARS-CoV-2 functional cellular responses.

Discrimination based on sexual orientation against MSM in Brazil: a latent class analysis.

INTRODUCTION: Discrimination based on sexual orientation can influence vulnerability to HIV, increasing exposure to risky sexual behavior among men who have sex with men (MSM). OBJECTIVES: To analyze data using latent class analysis (LCA) to identify groups of individuals with specific patterns of discrimination based on sexual orientation (DSO). METHODS: Cross-sectional study using respondent-driven sampling in 12 Brazilian cities in 2016. LCA was used to characterize discrimination among MSM based on 13 variables in the survey questionnaire. The proportions of men reporting DSO and other variables of interest were estimated using Gile's Successive Sampling estimator. RESULTS: Most MSM were young, single, had a religion, had a high school or college degree, black or brown skin color, and socioeconomic status classified as average. More than half of the participants reported that they had been discriminated against during the last 12 months due to their sexual orientation (65%), more than a third said they had felt afraid of walking in public places during the past 12 months, and about one-fifth of participants reported having been victims of physical or sexual assault due to DSO. DSO was classified into four latent classes: "very high", "high", "moderate" and "low", with estimates of 2.2%, 16.4%, 35.1%, and 46.19%, respectively. CONCLUSION: We observed a high proportion of discrimination against MSM in this study. The use of LCA differentiated parsimoniously classes of discrimination.

HIV testing coverage among female sex workers, Brazil, 2016.

INTRODUCTION: Knowing the factors associated with periodic HIV testing among female sex workers (FSW) is essential to expand testing coverage and to broaden programs of treatment as prevention. METHODS: We used data from 4,328 FSWs recruited by the respondent-driven sampling (RDS) method in 12 Brazilian cities in 2016. Data analysis considered the complex sampling design. The prevalence of HIV testing in the last year and periodic HIV test were estimated. Factors associated with regular HIV testing were identified through logistic regression models. RESULTS: The testing coverage in the last year was 39.3%. Only 13.5% of FSW reported having performed a periodic HIV test in the last year. Among the factors associated with the higher probability of HIV testing in the last year were a better level of education, living with a partner, working indoors, consistent use of condoms, and regular use of public and private health services stood out. DISCUSSION: Periodic HIV testing allows early diagnosis and immediate treatment of cases, reducing the chances of spreading the infection to the population. However, factors such as stigma and discrimination hinder the use of regular health services. CONCLUSION: It is necessary to expand awareness campaigns, especially among FSWs with low educational level and greater vulnerability, in order to broaden the perception of risk and the importance of periodic testing, in addition to encouraging regular health care.

The 12 city HIV Surveillance Survey among MSM in Brazil 2016 using respondent-driven sampling: a description of methods and RDS diagnostics.

INTRODUCTION: This paper details the methods used in the second national Biological and Behavioral Surveillance Survey (BBSS) of HIV, syphilis, and hepatitis B and C among men who have sex with men in Brazil. METHODS: Respondent-driven sampling (RDS) was used in 12 cities in 2016. The targeted sample size was initiated with five to six seeds in each city. HIV, syphilis, and Hepatitis B and C rapid tests were offered to participants. RDS Analyst with Gile's successive sampling (SS) estimator was used to adjust results as recommended and a weight for each individual was generated for further analysis. Data for the 12 cities were merged and analyzed using Stata 14.0 complex survey data tools with each city treated as its own stratum. RESULTS: Duration of data collection varied from 5.9 to 17.6 weeks. 4,176 men were recruited in the 12 cities. Two sites failed to achieve targeted sample size due to a six-month delay in local IRB approval. No city failed to reach convergence in our major outcome variable (HIV). CONCLUSION: The comprehensive BBSS was completed as planned and on budget. The description of methods here is more detailed than usual, due to new diagnostic tools and requirements of the new STROBE-RDS guidelines.

Combined spinal-epidural block for labor analgesia. Comparative study with continuous epidural block / Bloqueio combinado raquiperidural para analgesia de parto. Estudo comparativo com bloqueio peridural contínuo

Abstract Introduction: Lumbar epidural block is an effective and routinely used technique for labor pain relief, and the combined spinal-epidural block has the benefit of using lower doses of local anesthetics and rapid onset of analgesia. The objective of this study was to evaluate the effectiveness and safety of two anesthetic techniques: combined spinal-epidural block and continuous epidural block in pregnant women for labor analgesia. Methods: Eighty patients, ASA II and III, with cephalic presentation and cervical dilation between 5 and 6 cm, undergoing labor analgesia, allocated in two groups according to the anesthetic technique: combined spinal-epidural (GI) and continuous epidural (GII). Pain severity before the blockade, time to complete analgesia, degree of motor blockade, time to full cervical dilation, duration of the second stage of labor, pain severity during the 1st and 2nd stage of labor, type of delivery, use of oxytocin during labor, maternal cardiocirculatory and respiratory parameters and adverse events, and neonatal repercussions were recorded. Results: At the time of anesthesia, pain severity was similar in both groups. Pain relief was faster in GI (4.5 ± 1.5 min) when compared to GII (11.6 ± 4.6 min) p = 0.01; pain scores in the first and second stages of delivery were lower in GI (0.9 ± 0.3 and 1.8 ± 0.7, respectively) when compared to GII (1.9 ± 0.6 and 2.2 ± 0.5, respectively), with p = 0.01 only in the first stage of labor; there was need for local anesthetics supplementation in GII; there were more frequent spontaneous deliveries in GI (80% of patients) than in GII (50%) (p = 0.045) and more frequent use of instrumental (p = 0.03) in GII (12 patients) compared to GI (4 patients); the frequency of cesarean deliveries was significantly higher (p = 0.02) in Group II than in Group I, with 4 cases in GI and 8 cases in GII; absence of maternal cardiocirculatory and respiratory changes and neonatal repercussions; more frequent pruritus in GI (10 patients) and (0 patients in GII) (p = 0.02). Conclusion: The combined blockade proved to be effective with better quality of analgesia and greater comfort for pregnant women, constituting a good option for the practice of obstetric analgesia.

Resumo Introdução: O bloqueio peridural lombar constitui técnica eficaz e rotineiramente empregada para alívio da dor do parto e o bloqueio combinado raquiperidural tem como benefícios o emprego de doses menores de anestésicos locais e rápido início de analgesia. O objetivo do estudo foi avaliar comparativamente a eficácia e a segurança de duas técnicas anestésicas: bloqueio combinado raquiperidural e peridural contínua em grávidas submetidas à analgesia de parto. Método: Oitenta gestantes, ASA 2 e 3, apresentação cefálica e dilatação cervical entre cinco e seis centímetros, submetidas à analgesia de parto, distribuídas em dois grupos de acordo com a técnica anestésica: técnica combinada raquiperidural (GI) e peridural contínua (GII). Avaliaram-se: intensidade de dor antes do bloqueio; tempo para completa analgesia; grau do bloqueio motor; tempo para dilatação cervical total; duração do 2° estágio do trabalho de parto; intensidade de dor durante o 1° e o 2° estágio do trabalho de parto; tipo de parto; uso de ocitocina durante trabalho de parto; parâmetros cardiocirculatórios, respiratórios e eventos adversos maternos; repercussões neonatais. Resultados: No momento da anestesia a intensidade de dor era semelhante em ambos os grupos. O alívio da dor foi mais rápido no GI (4,5 ± 1,5 min) quando comparado com o GII (11,6 ± 4,6 min) p = 0,01; os escores de dor no primeiro e segundo estágios de parto foram menores no GI (0,9 ± 0,3) e (1,8 ± 0,7) quando comparados com o GII (1,9 ± 0,6) e (2,2 ± 0,5) com p = 0,01 somente no primeiro estágio de trabalho de parto; houve necessidade de complementação com anestésicos locais no GII; partos espontâneos mais frequentes em GI (80% das pacientes) do que em GII (50%) p = 0,045 e instrumentais mais frequentes (p = 0,03) em GII (12 pacientes) quando comparadas com o GI (quatro pacientes); a frequência de partos cesáreos foi significativamente maior (p = 0,02) no Grupo II do que no Grupo I, quatro casos no GI e oito no GII; ausência de alterações cardiocirculatórias e respiratórias maternas e repercussões neonatais; prurido mais frequente no GI (10 pacientes) e (0 paciente no GII) p = 0,02. Conclusão: O bloqueio combinado mostrou-se eficaz com melhor qualidade de analgesia e maior conforto às gestantes, constitui boa opção para a prática de analgesia obstétrica.

RESUMO Introdução: Conhecer os fatores associados ao teste periódico de HIV no grupo de mulheres trabalhadoras do sexo (MTS) é fundamental para expandir a cobertura de testagem e ampliar os programas de tratamento como prevenção. Métodos: Foram utilizados dados de 4.328 MTS recrutadas pela metodologia respondent-driven sampling (RDS) em 12 cidades brasileiras em 2016. A análise de dados considerou o desenho complexo de amostragem. Foram estimadas as prevalências de realização do teste de HIV no último ano e do teste periódico. Através de modelos de regressão logística foram identificados fatores associados à testagem regular de HIV. Resultados: A cobertura de teste no último ano foi de 39,3%. Apenas 13,5% das MTS relataram ter realizado teste periódico de HIV no último ano. Entre os fatores associados à maior probabilidade de realização de teste de HIV no último ano, destacaram-se o melhor nível de instrução, o fato de morar com companheiro, trabalhar em lugares fechados, o uso consistente de preservativo, e o uso regular de serviço de saúde público e privado. Discussão: A realização periódica de teste de HIV possibilita o diagnóstico precoce e o tratamento imediato dos casos, reduzindo as chances de disseminação da infecção na população. Entretanto, fatores como estigma e discriminação dificultam o uso regular de serviços de saúde. Conclusão: É necessário expandir campanhas de conscientização, sobretudo entre as MTS de baixo nível de instrução e maior vulnerabilidade, a fim de ampliar a percepção de risco e da importância da testagem periódica, além de incentivar os cuidados regulares de saúde.

RESUMO Introdução: A discriminação por orientação sexual (DPOS) pode influenciar a vulnerabilidade ao HIV aumentando a exposição a comportamentos sexuais de risco entre homens que fazem sexo com homens (HSH). Objetivos: Examinar dados utilizando a análise de classes latentes (ACL) para identificar grupos de indivíduos com padrões específicos de DPOS. Métodos: Estudo transversal com entrevistados recrutados pelo processo amostral respondent driven sampling em 12 cidades brasileiras em 2016. A ACL foi usada para caracterizar o DPOS entre HSH com base em 13 variáveis do bloco de discriminação do questionário da pesquisa. As proporções de DPOS e das variáveis de interesse, bem como seus intervalos de confiança (95%) foram ponderados usando o estimador de Gile. Resultados: A maioria era de jovens, solteiros, com alguma religião, escolaridade média ou superior, cor da pele preta ou parda e com nível socioeconômico médio. Mais da metade referiu ter sido discriminado nos últimos 12 meses por sua orientação sexual (65%), mais de um terço referiu ter tido medo de andar em lugares públicos nos últimos 12 meses e em torno de um quinto dos participantes reportaram ter sofrido agressão física ou sexual na vida. A DPOS foi classificada em 4 classes latentes, "muito alta", "alta", "média" e "baixa", com estimativas de 2,2%, 16,4%, 35,1% e 46,19%, respectivamente. Conclusão: Observou-se alta proporção de discriminação entre os HSH participantes deste estudo. A utilização da ACL discriminou de maneira parcimoniosa as classes de DPOS.

RESUMO: Introdução: Este artigo detalha os métodos utilizados na segunda Pesquisa Nacional de Vigilância Biológica e Comportamental (BBSS) do HIV, sífilis e hepatite B e C entre os homens que fazem sexo com homens no Brasil. Métodos: O método Respondent-driven Sampling (RDS) foi utilizado em 12 cidades em 2016. A amostra foi iniciada com cinco a seis sementes em cada cidade. Testes rápidos para o HIV, sífilis e Hepatite B e C foram oferecidos aos participantes. O software RDS Analyst com o estimador de amostragem sucessiva (SS) de Gile foi utilizado para ajustar os resultados como recomendado, gerando um peso para cada indivíduo para análises. Osdados das 12cidades foram unidos em um único banco e analisados usando as ferramentas de dados complexos do Stata 14.0, com cada cidade sendo tratada como seu próprio estrato. Resultados: A duração da coleta de dados variou de 5,9 a 17,6 semanas e 4.176 homens foram recrutados nas 12 cidades. Dois sites não alcançaram o tamanho da amostra alvo devido a uma demora de seis meses na aprovação local do Comitê de Ética. Todas as cidades atingiram a convergência na principal variável estudada (HIV). Conclusão: O BBSS foi representativo e concluído conforme planejado e dentro do orçamento. A descrição dos métodos aqui é mais detalhada do que o habitual, devido às novas ferramentas e requisitos de diagnóstico das novas diretrizes do STROBE-RDS.

Underreporting of Congenital Syphilis as a Cause of Fetal and Infant Deaths in Northeastern Brazil.

INTRODUCTION: Of all syphilis-related pregnancy outcomes, fetal death is certainly the most common one, being directly related to the availability, accessibility and quality of prenatal care. The present study aimed to analyze the underreporting of fetal and infant deaths and other maternal factors associated with congenital syphilis (CS) death. METHODS: This cross-sectional study integrated data of infants that were diagnosed and/or died of CS from the Sistema de Informação de Agravos de Notificação-Sinan (Notifiable Diseases Information System) and the Sistema de Informação de Mortalidade-SIM (Mortality Information System) in Fortaleza, Northeastern Brasil to identify unreported cases of congenital syphilis. We assessed data during the period from 2007 to 2013. RESULTS: The underreporting of CS as a cause of fetal or infant death increased from 41 to 415 cases (90.1%) during 2007-2013. Exactly 3,209 cases of CS were identified in Sinan and 6,578 deaths in SIM. After database linkage, we identified 382 cases that were reported in the SIM and SINAN databases consisting of 309 fetal deaths and 73 infant deaths related to CS. From the children notified at Sinan that born alive, 3.0% (78/2,542) died; Out of these, 39 (50.0%) were early and 25 (32.1%) were late neonatal deaths. The proportion of death by CS increased from 0.62 to 5.8 from 2007 to 2013. At logistic regression, the variable that maintained statistical significance with fetal and infant death outcomes was the presence of CS signs and/or symptoms at birth (OR = 3.20; IC 95% 1.54-6.62; p = 0.002). CONCLUSIONS: Neonatal and Infant deaths following CS-associated live births are underreported in Northeastern Brazil. Data base linkage identified unreported fetal and neonatal deaths due to CS leading to an increased awareness of fetal/infant mortality due to this infection.

[Prevalence of intimate partner violence and associated factors after disclosing the diagnosis of a sexually transmissible disease]. / Prevalência e fatores associados à violência entre parceiros íntimos após a revelação do diagnóstico de doenças sexualmente transmissíveis ao parceiro.

The objective of this study was to investigate factors associated with intimate partner violence after disclosing the diagnosis of sexually transmissible diseases (STDs) in Fortaleza, Ceará State, Brazil. This cross-sectional study enrolled 221 individuals treated at STD clinics. Multivariate logistic regression was performed. A total of 28.1% of individuals committed some type of intimate partner violence after disclosure of the diagnosis. Committing intimate partner violence was associated with alcohol use (OR = 2.79; 95%CI: 1.25-6.22; p = 0.012), the partner having relations with someone else during the current relationship (OR = 4.71; 95%CI: 2.24-9.91; p = 0.000), a history of violence prior to the STD (OR = 2.87; 95%CI: 1.22-6.73; p = 0.015), and having suffered violence after diagnosis of the STD (OR = 6.53; 95%CI: 3.06-13.93; p = 0.000). Intimate partner violence following disclosure of the STD signals that health professionals should identify patients' difficulties in revealing an STD diagnosis to their partners.

Association of lipophilic opioids and hyperbaric bupivacaine in spinal anesthesia for elective cesarean section. Randomized controlled study.

PURPOSE: To evaluate the efficacy and side-effects of fentanyl and sufentanil combined with hyperbaric spinal bupivacaine in elective cesarean section. METHODS: A prospective, randomized, double-blind study with 64 term parturients, distributed into 2 groups according to the opioid combined with hyperbaric bupivacaine 0.5% (10mg): GF - fentanyl (25 µg) and GS - sufentanil (5.0 µg). The latency and maximum sensory block level; degree and duration of motor block; duration and quality of analgesia; maternal-fetal repercussions were evaluated. This was an intention-to-treat analysis with a 5% significance level. RESULTS: The latency period, maximum sensory block level, motor block degree and perioperative analgesia were similar in both groups. Motor block and analgesia had a longer duration in the sufentanil group. Maternal adverse effects and neonatal repercussions were similar. The incidence of hypotension was higher in the fentanyl group. In both groups, there was a predominance of patients who were awake and either calm or sleepy. CONCLUSIONS: The addition of fentanyl and sufentanil to hyperbaric subarachnoid bupivacaine was shown to be effective for the performance of cesarean section, and safe for the mother and fetus. Analgesia was more prolonged with sufentanil.
