Risk factors for postpartum hemorrhage according to the Robson classification in a low-risk maternity hospital.

Objective: To evaluate the risk factors for postpartum hemorrhage (PPH) according to the Robson Classification in a low-risk maternity hospital. Methods: We conducted retrospective cohort study by analyzing the medical records of pregnant women attended in a low-risk maternity hospital, during from November 2019 to November 2021. Variables analyzed were: maternal age, type of delivery, birth weight, parity, Robson Classification, and causes of PPH. We compared the occurrence of PPH between pregnant women with spontaneous (Groups 1 and 3) and with induction of labor (2a and 4a). Chi-square and Student t-tests were performed. Variables were compared using binary logistic regression. Results: There were 11,935 deliveries during the study period. According to Robson's Classification, 48.2% were classified as 1 and 3 (Group I: 5,750/11,935) and 26.1% as 2a and 4a (Group II: 3,124/11,935). Group II had higher prevalence of PPH than Group I (3.5 vs. 2.7%, p=0.028). Labor induction increased the occurrence of PPH by 18.8% (RR: 1.188, 95% CI: 1.02-1.36, p=0.030). Model including forceps delivery [x2(3)=10.6, OR: 7.26, 95%CI: 3.32-15.84, R2 Nagelkerke: 0.011, p<0.001] and birth weight [x2(4)=59.0, OR: 1.001, 95%CI:1.001-1.001, R2 Nagelkerke: 0.033, p<0.001] was the best for predicting PPH in patients classified as Robson 1, 3, 2a, and 4a. Birth weight was poor predictor of PPH (area under ROC curve: 0.612, p<0.001, 95%CI: 0.572-0.653). Conclusion: Robson Classification 2a and 4a showed the highest rates of postpartum hemorrhage. The model including forceps delivery and birth weight was the best predictor for postpartum hemorrhage in Robson Classification 1, 3, 2a, and 4a.

Mode of delivery according to Robson classification and perinatal outcomes in restricted and small for gestational age fetuses.

Objective: To evaluate the mode of delivery according to Robson classification (RC) and the perinatal outcomes in fetal growth restriction (FGR) and small for gestational age (SGA) fetuses. Methods: Retrospective cohort study by analyzing medical records of singleton pregnancies from two consecutive years (2018 and 2019). FGR was defined according to Delphi Consensus. The Robson groups were divided into two intervals (1-5.1 and 5.2-10). Results: Total of 852 cases were included: FGR (n = 85), SGA (n = 20) and control (n=747). FGR showed higher percentages of newborns < 1,500 grams (p<0.001) and higher overall cesarean section (CS) rates (p<0.001). FGR had the highest rates of neonatal resuscitation and neonatal intensive care unit admission (p<0.001). SGA and control presented higher percentage of patients classified in 1 - 5.1 RC groups, while FGR had higher percentage in 5.2 - 10 RC groups (p<0.001). FGR, SGA and control did not differ in the mode of delivery in the 1-5.1 RC groups as all groups showed a higher percentage of vaginal deliveries (p=0.476). Conclusion: Fetuses with FGR had higher CS rates and worse perinatal outcomes than SGA and control fetuses. Most FGR fetuses were delivered by cesarean section and were allocated in 5.2 to 10 RC groups, while most SGA and control fetuses were allocated in 1 to 5.1 RC groups. Vaginal delivery occurred in nearly 60% of FGR allocated in 1-5.1 RC groups without a significant increase in perinatal morbidity. Therefore, the vaginal route should be considered in FGR fetuses.

Colony Age of Trichoderma azevedoi Alters the Profile of Volatile Organic Compounds and Ability to Suppress Sclerotinia sclerotiorum in Bean Plants.

Common bean (Phaseolus vulgaris L.) is one of the most important crops in human food production. The occurrence of diseases, such as white mold, caused by Sclerotinia sclerotiorum can limit the production of this legume. The use of Trichoderma has become an important strategy in the suppression of this disease. The aim of the present study was to evaluate the effect of volatile organic compounds (VOCs) emitted by Trichoderma azevedoi CEN1241 in five different growth periods on the severity of white mold in common bean. The in vitro assays were carried out in double-plate and split-plate, and the in vivo assays, through the exposure of the mycelia of S. sclerotiorum to the VOCs of T. azevedoi CEN1241 and subsequent inoculation in bean plants. Chemical analysis by gas chromatography coupled to mass spectrometry detected 37 VOCs produced by T. azevedoi CEN1241, covering six major chemical classes. The profile of VOCs produced by T. azevedoi CEN1241 varied according to colony age and was shown to be related to the ability of the biocontrol agent to suppress S. sclerotiorum. T. azevedoi CEN1241 VOCs reduced the size of S. sclerotiorum lesions on bean fragments in vitro and reduced disease severity in a greenhouse. This study demonstrated in a more applied way that the mechanism of antibiosis through the production of volatile compounds exerted by Trichoderma can complement other mechanisms, such as parasitism and competition, thus contributing to a better efficiency in the control of white mold in bean plants.

Transition of care in pediatric surgery.

OBJECTIVE: To identify among pediatric surgeons across Brazil how the transition of pediatric patients to adult clinics is carried out. METHODS: A questionnaire was emailed to pediatric surgeons registered with the Associação Brasileira de Cirurgia Pediátrica in 2018. The data assessed included training time, maximum age of care, subspecialty of practice, outpatient follow-up of adult patients, reason for continuing care of adult patients, referral to adult specialties, concern with transition of care, and what has been done to improve it. RESULTS: Most pediatric surgeons had more than 20 years of experience, and approximately 61% worked simultaneously at a public hospital, private hospital and private office. The maximum age of care at public, private hospitals and private offices proved to be quite varied. The follow-up of patients aged over 18 years at public hospitals, private hospitals and private clinics wase 32%, 23.58% and 20.75%, respectively. The main reason for patients aged over 18 years continued to be accompanied by pediatric surgeons was lack of knowledge about the disease by adult specialties. Most patients were referred to the adult specialty of the hospital, and roughly 37% of pediatric surgeons responded that they were in contact with the adult specialty. Most believed in autonomy of care of their patients and were concerned with transition of care. CONCLUSION: Transition of care is a relevant issue that needs to be studied and debated to ensure an appropriate long-term follow-up.

RESUMO Objetivo Identificar entre os cirurgiões pediátricos de todo o Brasil como é realizada a transição de cuidados dos pacientes pediátricos para as clínicas adultas. Métodos Um questionário foi enviado por e-mail para cirurgiões pediátricos cadastrados na Associação Brasileira de Cirurgia Pediátrica no ano de 2018. Foram avaliados dados como tempo de formação, idade máxima de atendimento, subespecialidade de atuação, seguimento ambulatorial de pacientes adultos, motivo pelo qual continuava atendendo pacientes adultos, encaminhamento para especialidades adultas, preocupação com a transição de cuidados e o que tinha realizado para aprimorá-la. Resultados A maioria dos cirurgiões pediátricos tinha mais de 20 anos de experiência, e cerca de 61% atuavam simultaneamente em hospital público, hospital privado e clínica privada. A idade máxima de atendimento nos hospitais públicos e privados e nas clínicas privadas mostrou-se bastante variada. O acompanhamento de pacientes acima de 18 anos nos hospitais públicos, nos hospitais privados e nas clínicas privadas foi, respectivamente, 32%, 23,58% e 20,75%. O principal motivo pelo qual o paciente acima de 18 anos continuava sendo acompanhado por cirurgiões pediátricos foi falta de conhecimento da patologia pelas especialidades adulta. A maioria dos pacientes era encaminhada para a especialidade adulta do próprio hospital, e cerca de 37% dos cirurgiões pediátricos responderam que mantinham contato com a especialidade adulta. A maioria acreditava na autonomia de cuidados de seus pacientes e estava preocupada com a transição de cuidados. Conclusão A transição de cuidados é um assunto relevante e que precisa ser estudado e debatido para que se possa assegurar um adequado seguimento a longo prazo.

Immunolocalization of HLA-DR and metallothionein on amalgam tattoos.

Despite studies concerning toxic reactions related to amalgam components in the literature, few studies have been devoted to evaluate local noxious effects of amalgam tattoos (AT) on biological tissues. In addition, little is known about activation of inflammatory cells by mucosa-implanted amalgam debris. Tissue reaction to AT depends on the particle size. Human leukocyte antigen DR (HLA-DR) is an activation marker of inflammatory cells associated with antigen presentation. Metallothioneins (MT) are proteins involved with metal detoxication, including mercury and silver. The purpose of the present study was to investigate the immunolocalization of HLA-DR and MT in AT with large or powdered particles. Paraffin-embedded AT tissue blocks were sectioned and subjected to immunohistochemistry for HLA-DR and MT localization. The results demonstrated a dense mononuclear inflammatory infiltrate associated with large and powdered debris and positivity for HLA-DR and MT in inflammatory cells. While blood vessel walls and connective fibers impregnated with powdered particles were negative for HLA-DR, they were positive for MT. In addition, wherever epithelial basement membrane impregnation by powdered amalgam particles was observed, a strong positivity for MT was detected. These findings demonstrate that residual elements of AT still have noxious local effects over tissues.

Avaliação de parâmetros microbiológicos, físico-químico e de rotulagem de produtos lácteos com análises não conformes registrados no Serviço de Inspeção Estadual de Santa Catarina / Evaluation of microbiological standards, physical-chemical and labeling of dairy products with non-conforming analyzes registered at Santa Catarina State Inspection Service

Ensaios laboratoriais representam uma estratégia importante para garantir a produção de alimentos seguros. O objetivo deste trabalho foi avaliar os tipos de produtos lácteos não conformes produzidos em estabelecimentos registrados no Serviço de Inspeção de Santa Catarina (SIE), identificar a localização dos estabelecimentos produtores e o tipo de não conformidades encontradas. Foram avaliados laudos do Laboratório de Saúde Pública durante o período de janeiro de 2016 até outubro de 2018. Dos 27 laudos não conformes, 26 eram queijos e um iogurte. Tubarão e Rio do Sul foram as regiões de Santa Catarina que apresentaram o maior número de produtos não conformes, sendo erros de rotulagem a principal inconformidade. Os dados obtidos comprovam a importância de trabalhos conjuntos de fiscalização (Vigilância Sanitária e SIE), atividade que otimiza recursos e oferece segurança alimentar aos consumidores.

Saúde e jornalismo: o que dizem os estudos sobre a produção noticiosa sobre o SUS?

Desde os primeiros momentos de construção do Sistema Único de Saúde (SUS), foi reconhecida a importância da produção jornalística sobre o projeto e o que implica para a garantia do direito constitucional à saúde. Além de tema de debates em instâncias de participação social, esses discursos também se constituíram como destacado objeto de pesquisas no campo da comunicação e saúde. Geral: Analisar os estudos brasileiros dedicados à produção jornalística sobre o SUS. Específicos: i) Identificar as perspectivas teórico-metodológicas que orientam esses estudos. ii) Mapear as principais temáticas, resultados e controvérsias. Revisão narrativa dos estudos dedicados à cobertura jornalística sobre o SUS, em meios impressos, televisivos, radiofônicos, blogs e redes sociais. O corpus é formado por artigos, livros e capítulos de coletâneas. Para os artigos, definiu-se como critério de inclusão aqueles publicados em periódicos vinculados a instituições e/ou voltados para a produção de conhecimento no campo da Saúde Coletiva. Na produção identificada, destacam-se os estudos qualitativos e as abordagens orientadas pela Análise de Conteúdo e Análise de Discurso. Teorias consolidadas para a análise do jornalismo ­ como a da Agenda Setting e do Enquadramento ­ também são marcantes. Há largo predomínio do componente assistencial, com ênfase nas falhas, má gestão e insuficiências para fazer valer o direito à saúde. As fontes mais ouvidas são as autoridades sanitárias e especialistas do campo bio-médico. A presença de doentes, familiares e usuários varia segundo o tema, o veículo e a gravidade da situação. O SUS não é nomeado com frequência e é praticamente inexistente a referência às instâncias de participação social. Destacam-se os diferentes posicionamentos frente às credenciais de objetividade, imparcialidade e neutralidade reivindicadas pelo jornalismo. A ausência de diálogo com perspectivas que investigam as especificidades do jornalismo brasileiro, como a hipótese de sua atuação como poder moderador (e não quarto poder) e meta-sistema perito, também merece atenção pelo que deixam aportar à compreensão sobre as formas de legitimação desses discursos.

Immunolocalization of HLA-DR and metallothionein on amalgam tattoos

Poucos estudos têm investigado a toxicidade tecidual local das tatuagens por amálgama (TA), embora diversos trabalhos demonstrem efeitos nocivos desse material restaurador. Pouco se sabe sobre a ativação de células inflamatórias nesse tipo de lesão. A reação tecidual contra os restos de amálgama varia com o tamanho das partículas implantadas. O antígeno leucocitário humano DR (HLA-DR) está associado com a ativação de células inflamatórias, sendo relacionado à apresentação de antígeno. Metalotioneínas (MT) são proteínas envolvidas com neutralização de metais pesados, tais como mercúrio e prata. O objetivo do presente trabalho foi investigar a imunolocalização de HLA-DR e MT em TA compostas por depósitos teciduais de diferentes tamanhos. Cortes histológicos de lesões fixadas em formol e embebidas em parafina foram submetidos a técnica imunoistoquímica para a detecção dos antígenos mencionados. Os resultados demonstraram denso infiltrado inflamatório associado com partículas grandes ou pulverizadas, observando-se presença de células HLA-DR e MT positivas. Paredes de vasos sangüíneos e fibras de tecido conjuntivo impregnadas por restos de amálgama foram negativas para HLA-DR, mas positivas para MT. Impregnação da membrana basal por partículas de amálgama correspondia a forte positividade para MT no epitélio. Esses resultados demonstram a existência de efeitos nocivos locais das TA sobre os tecidos.
