Abstract This study scrutinizes structural racism’s influence on the training and work of Black professionals in primary health care (PHC) in Rio de Janeiro, particularly focusing on the experiences of Black female physicians. Employing a qualitative approach via a Focus Group, conducted in November 2022, we adopted symbolic interactionism to interpret racism-related experiences. Our findings encompass two primary dimensions: the manifestation of structural and institutional racism within the Unified Health System (SUS), and how racism permeates health work processes and consequences. Results highlight enduring impacts, spanning education to PHC roles, hindering healthcare process recalibration. Participants identify institutional and structural racism, from managerial neglect to territorial violence and physician scarcity, constraining comprehensive care. It is crucial to unveil and grasp racism’s structural essence within healthcare, aligned with the vision of health as a fundamental right.

Resumo Trata-se de estudo sobre o racismo estrutural na formação e na ocupação de trabalhadoras e trabalhadores negros atuando na atenção primária à saúde (APS) no município do Rio de Janeiro, a partir da experiência de médicas negras. Realizou-se um estudo qualitativo, utilizando grupo focal, conduzido em novembro de 2022. Utilizou-se o interacionismo simbólico como referência para a interpretação relacionada às situações que compõem as experiências/vivências a partir do racismo. Os achados foram reunidos em dois eixos: manifestação do racismo estrutural e institucional no âmbito do SUS; e como o racismo atravessa os processos de trabalho em saúde e suas repercussões. Os resultados revelam uma continuidade das implicações do racismo desde a formação de médicas negras até o trabalho na APS, tornando-se um obstáculo na reorganização do processo de trabalho na perspectiva territorial de atenção à saúde. As participantes identificam o racismo institucional e estrutural na negligência da gestão, na violência do território e na vacância de médicos nas equipes desses territórios, limitando a oferta de um cuidado adequado. É necessário desvelar e aprofundar a compreensão do caráter estrutural do racismo da organização do trabalho em saúde, tendo como imagem-objetivo a saúde como direito.

ABSTRACT: This study evaluated the probability of pregnancy and associated factors for two times artificial inseminations (AI), 8 or 10 hours after automated activity monitoring (AAM) alarm on the first postpartum AI of 1,054 Holstein dairy cows. The estrus was synchronized by prostaglandin or estradiol-progesterone program. Stepwise logistic regression was performed to analyze the probability of pregnancy, and associated factors (activity, estrus intensity, parity, peripartum health, retained placenta, postpartum vaginal discharge, and season). The highest pregnancy rates were obtained with multiparous animals, inseminated ten hours after the AAM alarm, in the fall or winter season, with a high activity peak and estrus intensity (P < 0.05). Peripartum diseases, retained placenta, and postpartum vaginal discharge negatively influenced the pregnancy rate, regardless of parity. Thus, the optimization of AAM models by including on-farm measures like parity, peripartum health history, and environmental conditions may favor the correct identification of estrus and improve the AAM alarm regarding the ideal moment for AI, increasing the reproductive performance in dairy cows.

RESUMO: O objetivo deste estudo foi avaliar a probabilidade de prenhez e fatores associados para dois horários de inseminação artificial (IA), oito ou 10 horas após o alarme de monitoramento automatizado de atividades (AAM), na primeira IA pós-parto em 1.054 vacas leiteiras da raça Holandês. O estro foi sincronizado por protocolos a base de prostaglandina ou estradiol-progesterona. Regressão logística stepwise foi realizada para analisar a probabilidade de prenhez e fatores associados (atividade, intensidade do estro, paridade, saúde no periparto, placenta retida, descarga vaginal pós-parto e estação do ano). As maiores taxas de prenhez foram obtidas em multíparas, inseminadas 10 horas após o alarme do AAM, no outono ou inverno, com pico de atividade elevado e intensidade de estro (P < 0,05). Doenças no periparto, placenta retida e descarga vaginal pós-parto influenciaram negativamente a taxa de prenhez, independentemente da paridade. Assim, a otimização dos modelos de AAM, incluindo medidas rotineiras da fazenda como paridade, histórico de saúde no periparto e condições ambientais, podem favorecer a identificação correta do estro e melhorar o alarme do AAM em relação ao momento ideal para a IA, aumentando o desempenho reprodutivo nas vacas leiteiras.

ABSTRACT BACKGROUND: The High Activity Arthroplasty Score (HAAS) is a self-administered questionnaire, developed in British English, that reliably and validly measures the levels of sports activities in patients following hip and knee arthroplasty surgery. OBJECTIVE: To cross-culturally adapt the HAAS to Brazilian Portuguese language. DESIGN AND SETTING: A cross-sectional study was conducted at a public university hospital in Brazil. METHODS: The Brazilian version of the HAAS was created through a six-step process: translation, synthesis, committee review, pretesting, back-translation, and submission to developers. The translation step was conducted by two independent bilingual translators, both native speakers of Brazilian Portuguese. The back-translation was performed by an independent translator, a native speaker of British English. To ensure the questionnaire's comprehensibility, 46 volunteers (51% men; average age 34-63) participated in the pre-testing step. RESULTS: The cross-cultural adaptation process necessitated modifications to certain terms and expressions to achieve cultural equivalence with the original HAAS. CONCLUSION: The HAAS has been translated from English into Brazilian Portuguese and culturally adapted for Brazil. The validation process for HAAS-Brazil is currently underway.

ABSTRACT Purpose The objective of this study was analyzed the neuropsychological functions of students from a public school in Brazil, enrolled in the 1st and 2nd year of Elementary School at the time of the reopening of schools during the COVID-19 pandemic and to access the influence of family and contextual information on the performance of these skills. Methods 117 students participated in the study, as well as their parents or guardians. The children were evaluated in person using the Brief Child Neuropsychological Assessment Instrument (NEUPSILIN-Inf). The parents/guardians answered remotely the Inventory of Resources of the Family Environment and questions about socioeconomic classification and maternal education. Results The data showed a high prevalence of children who had problems or deficits in the functions of orientation, memory, language, visuospatial skills, arithmetic skills and verbal fluency. Furthermore, predictable activities that signal some degree of stability in family life are predictors of children's performance in orientation skills and resources that promote proximal processes significantly reflect on language performance. The results suggest that children included in families with a household income below one Brazilian minimum monthly salary presented poorer inhibitory control performances. Conclusion The impact of changes in neuropsychological skills in children's learning were presented and discussed, highlighting the need for immediate and targeted intervention of these functions. Contextual factors that influenced the performance of neuropsychological skills were also considered.

RESUMO Objetivo O objetivo desse estudo foi analisar as funções neuropsicológicas de estudantes de uma escola pública do Distrito Federal (Brasil), matriculadas 1º e 2º ano de Ensino Fundamental na reabertura das escolas públicas na pandemia da COVID-19 e a influência dos fatores familiares e contextuais sobre o desempenho dessas habilidades. Métodos Participaram 117 estudantes, bem como seus responsáveis. As crianças foram avaliadas presencialmente por meio do Instrumento de Avaliação Neuropsicológica Breve Infantil (NEUPSILIN-Inf). Os pais/responsáveis responderam remotamente ao Inventário de Recursos do Ambiente Familiar e as questões para classificação socioeconômica e de escolaridade materna. Resultado Os dados apontam alta prevalência de crianças em fase de alfabetização que apresentam alerta ou déficit das funções de orientação, memória, linguagem, habilidades visuoespaciais, habilidades aritméticas e fluência verbal. Ainda, as atividades previsíveis que sinalizam algum grau de estabilidade na vida familiar são preditoras do desempenho das crianças na habilidade de orientação e os recursos que promovem processos proximais refletem significativamente no desempenho em linguagem. Os resultados sugerem que crianças inseridas em família com estimativas da renda domiciliar abaixo de um salário mínimo apresentam piores desempenhos do controle inibitório. Conclusão Foram apresentados e discutidos os impactos das alterações das habilidades neuropsicológicas para o aprendizado das crianças, destacando a necessidade de intervenções imediatas e direcionadas para essas funções. Foram considerados os fatores contextuais que apresentaram influência sobre o desempenho das habilidades neuropsicológicas.

ABSTRACT Patients undergoing hematopoietic stem cell transplantation (HSCT) might present acute and late toxicities and the oral tissues are frequently affected. With the survival increasing, patients show late and long-term morbidities, and there is an important association between the general and the oral health. The first and second parts of this Consensus have showed the importance of the adequacy of oral health in the pre-HSCT, and the main alterations and oral care during the period of admission for HSCT. This third part aims to review specific themes of post-HSCT dental care, such as graft-versus-host disease (GVHD) and the pediatric patient. It also aims to review pertinent subjects, both during the HSCT period and post-HSCT, concerning quality of life, pain, cost-effectiveness, and remote care. Based on this review, it is evident the importance of the work of the dental surgeon (DS) in the follow-up and treatment of the HSCT patient, always collaborating with the whole multidisciplinary team.

ABSTRACT During the state of immune vulnerability in hematopoietic stem cell transplantation (HSCT), the patient has an increased risk of developing a vast number of complications, including severe problems in the oral cavity. These situations require professional oral care to act in the diagnosis and treatment of these conditions, as well as to develop prevention protocols to minimize patient's complications. Oral mucositis, opportunistic infections, bleeding, specific microbiota, taste, and salivary alterations are complications that can occur during HSCT and interfere with various aspects, such as pain control, oral intake, nutrition, bacteremia and sepsis, days of hospitalization and morbidity. Several guidelines have been published to address the role of professional oral care during the HSCT, we describe a consensus regarding these recommendations.

ABSTRACT The oral involvement in the Hematopoietic Stem Cell Transplantation is well described in the literature. The goal of the dental treatment and management of the oral lesions related to the HSCT is to reduce the harm caused by preexisting oral infection or even the worsening of oral acute/chronic GVHD and late effects. The aim of this guideline was to discuss the dental management of patients subjected to HSCT, considering three phases of the HSCT: pre-HSCT, acute phase, and late phase. The literature published from 2010 to 2020 was reviewed in order to identify dental interventions in this patient population. The selected papers were divided into three groups: pre-HSCT, acute and late, and were reviewed by the SBTMO Dental Committee's members. When necessary, an expertise opinion was considered for better translating the guideline recommendations to our population dental characteristics. This manuscript focused on the pre-HSCT dental management. The objective of the pre-HSCT dental management is to identify possible dental situations that On behalf of the Dental Committee of the Brazilian Society of Gene Therapy and Bone Marrow Transplantation (SBTMO) can worsening during the acute phase after the HSCT. Each guideline recommendations were made considering the Dentistry Specialties. The clinical consensus on dental management prior to HSCT provides professional health caregivers with clinical setting-specific information to help with the management of dental problems in patients to be subjected to HSCT.

Abstract Background Infantile epileptic spasms syndrome (IESS) is a rare but severe condition affecting children early and is usually secondary to an identifiable brain disorder. It is related to psychomotor deterioration in childhood and epilepsy in adult life. Treatment is challenging as infantile spasms may not respond to most antiseizure medication, and relapse is frequent. Objective To evaluate the literature regarding treatment of IESS and provide a practical guidance to a healthcare system with limited resources. Methods An expert committee from the Brazilian Society of Child Neurology reviewed and discussed relevant scientific evidence in the treatment of IESS regarding the drugs available in Brazil. Results Oral prednisolone and vigabatrin are the most common drugs used as first-line therapy; they are efficient and affordable therapy as both are available in the Brazilian unified health system (SUS, in the Portuguese acronym). Intramuscular adrenocorticotropic hormone (ACTH) presents similar efficacy as oral prednisolone but has a higher cost and is not available in Brazil. Other antiseizure medications such as topiramate, levetiracetam, or benzodiazepines have limited response and are prescribed as adjuvant therapy. If the health service has nutritionists, a ketogenic diet should be implemented for those not responding to hormonal and vigabatrin treatment. Epilepsy surgery is mainly indicated for patients with focal lesions that do not respond to pharmacological therapy. Conclusion Early treatment of IESS with efficient drugs is feasible in our country. Using standard protocols increases the odds of achieving complete cessation in a shorter time and decreases relapse.

Resumo Antecedentes A síndrome do espasmo epiléptico infantil (IESS) é uma condição rara, mas grave, que afeta crianças precocemente e geralmente é secundária a um distúrbio cerebral identificável, estando relacionada a deterioração psicomotora na infância e a epilepsia na vida adulta. O tratamento é desafiador, pois os espasmos infantis podem não responder à maioria dos medicamentos anticrises e as recidivas são frequentes. Objetivo Avaliar a literatura sobre o tratamento de IESS e fornecer uma orientação prática para um sistema de saúde com recursos limitados. Métodos Um comitê de especialistas da Sociedade Brasileira de Neurologia Infantil revisou e discutiu evidências científicas relevantes no tratamento da IESS em relação aos medicamentos disponíveis no Brasil. Resultados Prednisolona oral e vigabatrina são os fármacos mais comumente usados como terapia de primeira linha; são eficientes e acessíveis, já que ambos estão disponíveis no sistema único de saúde brasileiro (SUS). O ACTH intramuscular apresenta eficácia semelhante à prednisolona oral, mas tem custo mais elevado e não está disponível no Brasil. Outros medicamentos anticonvulsivos, como topiramato, levetiracetam ou benzodiazepínicos, têm resposta limitada e são prescritos como terapia adjuvante. Se o serviço de saúde tiver nutricionista, deve-se implementar dieta cetogênica para aqueles que não respondem ao tratamento hormonal e vigabatrina. A cirurgia de epilepsia é indicada principalmente para pacientes com lesões focais que não respondem à terapia farmacológica. Conclusão O tratamento precoce da IESS com fármacos eficazes é factível em nosso meio. O uso de protocolos padronizados aumenta as chances de alcançar a cessação completa em um tempo menor e diminui a recaída.

Abstract Introduction: Urinary catheter-related infection is commonly associated with bacterial biofilm. The impact of anaerobes is unknown, but their detection in the biofilm on this device has not been previously reported. This study aimed to evaluate the capability to recovery strict, facultative, and aerobic microorganisms in patients using bladder catheters from ICUs using conventional culture, sonication, urinary analysis, and mass spectrometry. Methods: Parallel, sonicated bladder catheters from 29 critically ill patients were compared with their routine urine culture. Identification was performed using matrix-assisted laser desorption/ionization with time-of-flight mass spectrometry. Results: The positivity rate in urine (n = 2, 3.4%) was lower than that in sonicated catheters (n = 7, 13.8%). Conclusion: Bladder catheter sonication showed more positive culture results than urine samples for anaerobic and aerobic microorganisms. The role of anaerobes in urinary tract infection and catheter biofilm is discussed.

Resumo Introdução: A infecção relacionada ao cateter urinário é comumente associada ao biofilme bacteriano. O impacto dos anaeróbios é desconhecido, mas sua detecção no biofilme deste dispositivo não foi relatada anteriormente. Este estudo teve como objetivo avaliar a capacidade de recuperar microrganismos estritos, facultativos e aeróbios em pacientes que utilizam cateteres vesicais de UTIs utilizando cultura convencional, sonicação, análise urinária e espectrometria de massa. Métodos: Paralelamente, foram comparados cateteres vesicais sonicados de 29 pacientes gravemente enfermos com sua urocultura de rotina. A identificação foi realizada utilizando dessorção/ionização a laser assistida por matriz com espectrometria de massa por tempo de voo. Resultados: A taxa de positividade na urina (n = 2; 3,4%) foi inferior à dos cateteres sonicados (n = 7; 13,8%). Conclusão: A sonicação do cateter vesical apresentou resultados de cultura mais positivos do que as amostras de urina para microrganismos anaeróbios e aeróbios. É discutido o papel dos anaeróbios na infecção do trato urinário e no biofilme do cateter.

Objective: As the older population increases, it is important to identify factors that may reduce the risks of dementia in the general population. One such factor is the concept of cognitive reserve (CR). The present study analyzed the psychometric properties of the Cognitive Reserve Assessment Scale in Health (CRASH) in the Brazilian population. This scale was originally developed to measure CR in individuals with severe mental illness. We also investigated the relationship between the CRASH and clinical or sociodemographic variables. Methods: This study was conducted with 398 individuals. We assessed sociodemographic variables and depression, anxiety, and stress symptoms (Depression, Anxiety and Stress Scale [DASS-21]) using a web-based survey. We constructed a confirmatory factor analysis (CFA) model in order to test the goodness of fit of the factor structure proposed in the original CRASH study. Results: The McDonald’s hierarchical ω for CRASH using CFA parameters was 0.61, and the Cronbach’s alpha coefficient indicated good internal consistency when considering all items (alpha = 0.7). Conclusions: Our results suggest that CRASH can be used to assess CR in the general population in Brazil.

Abstract The study aimed to evaluate relative validity and reproducibility of seven WHO indicators of dietary practices in children aged 6-23.9 months. Data from probabilistic sample of children who used primary healthcare services in Rio de Janeiro, Brazil were collected using a 24h dietary recall (24HR) and a closed questionnaire (Q1) on feeding in the day before the study. The last one was reapplied (Q2) around 16 days later. Validity was assessed by comparing the prevalence rates estimated by 24HR and Q1 and calculating the positive (PPV) and negative (NPV) predictive values, sensitivity (Se), specificity (Sp), and accuracy index (AI) for the resulting indicators. For reproducibility, estimated prevalence rates based on Q1 and Q2 were compared and the kappa index and prevalence-adjusted bias-adjusted kappa were estimated. Of the seven estimated indicators, the prevalence of two was overestimated (Continued breastfeeding: 50.0% vs 40.0%; Sweet beverage consumption: 65.1% vs 52.7%) and the prevalence of one was underestimated (Zero vegetable or fruit consumption: 6.5% vs 18.1%). For most indicators, Se and PPV were higher than Sp and NPV. The prevalence rates determined with Q1 and Q2 were similar for 6 indicators. More than half showed good, very good or excellent agreement.

Resumo O estudo avaliou a validade relativa e a reprodutibilidade de sete indicadores da OMS sobre alimentação de crianças de 6-23,9 meses. Dados de amostra probabilística de usuários de serviços básicos de saúde na cidade do Rio de Janeiro, Brasil, foram coletados por meio de recordatório alimentar de 24 horas (R24h) e questionário fechado (Q1) sobre alimentação no dia anterior ao estudo. Este último foi reaplicado (Q2) em torno de 16 dias depois. A validade foi avaliada comparando-se as prevalências estimadas pelo R24h e Q1 e calculando-se os valores preditivos positivo (VPP) e negativo (VPN), sensibilidade (Se), especificidade (Esp) e índice de acurácia (IA) dos indicadores resultantes. Para reprodutibilidade, as prevalências estimadas com base em Q1 e Q2 foram comparadas e estimados o índice kappa e o kappa ajustado pela prevalência. Dos sete indicadores estimados, houve superestimação da prevalência de dois (aleitamento continuado: 50,0% versus 40,0%; consumo de bebidas adoçadas: 65,1% vs. 52,7%) e subestimação da prevalência de um (não consumo de frutas e hortaliças: 6,5% vs. 18,1%). Para a maioria deles, Se e VPP foram maiores do que Esp e VPN. As prevalências determinadas com Q1 e Q2 foram semelhantes para seis indicadores. Mais da metade dos indicadores apresentaram concordância boa, muito boa ou excelente.

SUMMARY OBJECTIVE: This study aimed to evaluate the influence of chronic pain on functionality and its consequences on work and patient income. METHODS: A total of 103 patients from the Multidisciplinary Pain Center of the Clinics Hospital of Universidade Federal de Minas Gerais were interviewed between January 2020 and June 2021, applying questionnaires on mobile devices. Socioeconomic data, multidimensional characterization of pain, and instruments for assessing pain functionality and intensity were analyzed. Pain intensity was categorized as mild, moderate, or intense for comparative analysis. Ordinal logistic regression was used to identify risk factors and variables that jointly influence the outcome of pain intensity. RESULTS: The patients had a median age of 55 years, were predominantly female, married or in a stable relationship, white race, and completed high school. The median family income was R$2,200. Most patients were retired due to disability and pain-related causes. Functionality analysis showed severe disability directly associated with pain intensity. The financial impacts observed were correlated with the pain intensity of the patients. Age was a risk factor for pain intensity, while sex, family income, and duration of pain served as protective factors. CONCLUSION: Chronic pain was associated with severe disability, decreased productivity, and exit from the labor market, with a negative impact on financial condition. Age, sex, family income, and duration of pain were directly associated with pain intensity.

RESUMO: Objetivou-se com o estudo detectar Cryptosporidium sp. em ostras de cultivo e estoque natural no estado do Maranhão e determinar o(s) tecido(s) eletivo(s) para pesquisa desse protozoário. Para a realização do estudo foram adquiridas 200 ostras de cultivo do município de Raposa e 100 de Paço do Lumiar, além de 100 ostras extraídas de estoque natural do município de Primeira Cruz, totalizando 400 ostras. Estas foram agrupadas em 80 pools constituídos por cinco animais. De cada pool, as brânquias e a massa visceral foram removidas totalizando 160 pools, sendo 80 para o grupo das brânquias e 80 para o grupo de massa visceral. Na sequência, procedeu-se à extração de DNA de cada pool com a utilização de kit comercial com modificações. Posteriormente, realizou-se a detecção do DNA do protozoário por meio da técnica de Nested-PCR. Com a técnica utilizada, foi detectado o DNA do protozoário pesquisado em 2,5% (n=2/80) pools apenas de brânquias, sendo 1,25% pools (n=1/80) oriundos de cultivo e os outros 1,25% (n=1/80) de estoque natural. Com os resultados obtidos nesse estudo, conclui-se que as ostras analisadas do gênero Crassostrea sp., oriundas de cultivo e estoque natural no estado do Maranhão, estavam contaminadas por Cryptosporidium sp. e podem se reverter em fontes potenciais para seres humanos e outros animais. Para a pesquisa de Cryptosporidium sp. em ostras, as brânquias são o tecido eletivo.

ABSTRACT: This study detected Cryptosporidium spp. in cultivated oysters and the natural oyster stock of the state of Maranhão and determine the elective tissue(s) to examine this protozoan. For this purpose, 200 cultivated oysters were purchased from the municipality of Raposa and another 100 from Paço do Lumiar. Additionally, 100 oysters were extracted from the natural stock of the municipality of Primeira Cruz, thus making up a total of 400 oysters. They were grouped into 80 pools consisting of 5 oysters each. From each pool, the gills and visceral mass were removed to obtain 160 pools, 80 pools for the gill group and another 80 for the visceral mass group. Then, DNA was extracted from each pool using a commercial kit with modifications. Subsequently, the protozoan DNA was detected using nested polymerase chain reaction. With this technique, the DNA of the protozoan under investigation was detected in 2.5% (n = 2/80) of the pools containing gills, with 1.25% of the pools (n = 1/80) belonging to the cultivation group of oysters and the other 1.25% (n = 1/80) to the natural stock. With the results obtained in this study, it was concluded that the analyzed oysters of the genus Crassostrea, from cultivation and natural stock groups, found in the state of Maranhão, were contaminated by Cryptosporidium spp. and may become potential sources of infection in humans and other animals. In addition, the gills are the elective tissue for the study of Cryptosporidium spp. in oysters.
