Maternal and neonatal cortisol and catecholamines throughout vaginal eutocia and C-section in dogs.

Increased fetal cortisol is associated with catecholamine release, a primary factor for neonatal adaptive responses. However, relationship between canine peripartum cortisol and catecholamine is unknown. We aimed to compare serum adrenaline, noradrenaline and cortisol during peripartum in bitches and neonates of distinct obstetric conditions and to assess amniotic fluid cortisol concentration. Twenty females and maximum of three puppies per litter were allocated into Vaginal Eutocia (10 females; 17 neonates) and Elective C-section (10 females; 20 neonates) groups. Amniotic fluid was collected at delivery for cortisol concentration. Maternal and neonatal blood were collected prepartum, intrapartum, postpartum and 1h postpartum, and at birth, 30 and 60min, 12hs and 24hs, respectively, for cortisol, adrenaline and noradrenaline assessment. C-section determined higher noradrenaline throughout delivery and cortisol concentration from intrapartum through 1h postpartum, compared to vaginal birth. C-section maternal cortisol showed progressive increase from intrapartum onwards, while neonatal cortisol remained unchanged. No difference of maternal cortisol concentration occurred along whelping, whereas a significant decrease was verified for vaginal delivery puppies from birth until the 12hs. Puppies delivered vaginally had higher cortisol concentration at birth and 30min, compared to c-section puppies. There was a higher concentration of amniotic fluid cortisol in vaginal eutocia. In conclusion, c-section induces higher maternal stress during and after surgery, whilst vaginal delivery is a more neonatal physiologically stressful condition, contributing to better adaptation during transition.

Apoio social na prática de atividade física de trabalhadores / Apoyo social en la práctica de actividad física de trabajadores / Social support in workers' physical activity

Resumo Objetivo Analisar a função dos apoios sociais formal e informal na prática de atividade física durante o tempo livre de trabalhadores. Métodos Estudo transversal realizado com 395 trabalhadores técnicos administrativos em uma universidade pública. Os dados foram coletados utilizando: questionário sociodemográfico, Questionário de Atividade Física Habitual de Baecke e Escala de Apoio Social para a prática de Atividade Física. Os dados foram analisados por meio de estatística descritiva, teste t de Student, teste d de Cohen e Análise de Variância. Resultados Os participantes que referiram algum tipo de apoio para atividade física no tempo livre (92,2%) apresentaram maiores médias no escore de atividade física. O apoio institucional (58,0%) teve função de destaque como potencial influenciador em comparação ao apoio de chefias imediatas (14,2%), embora elas tenham exercido um certo diferencial entre os trabalhadores da manutenção. Conclusão O apoio social tem função importante na promoção da atividade física no tempo livre de trabalhadores. As iniciativas institucionais de estímulo ao comportamento ativo no ambiente de trabalho carecem de alinhamento com o incentivo por parte dos superiores imediatos, para que sejam mais efetivas.

Abstract Objective To analyze the role of formal and informal social support in the practice of physical activity during workers' leisure time. Methods A cross-sectional study carried out with 395 technical administrative workers at a public university. Data were collected using sociodemographic questionnaire, Baecke Habitual Physical Activity Questionnaire and Physical Activity and Social Support Scale. Data were analyzed using descriptive statistics, Student's t test, Cohen's d test and Analysis of Variance. Results Participants who reported some type of support for physical activity in their leisure time (92.2%) had higher means in the physical activity score. Institutional support (58.0%) had a prominent role as a potential influencer compared to support from immediate superiors (14.2%), although they had a certain differential among maintenance workers. Conclusion Social support plays an important role in promoting physical activity in workers' leisure time. Institutional initiatives to encourage active behavior in the work environment need to be aligned with encouragement by immediate superiors so that they are more effective.

Imaging findings of acute calcific periarthritis, with emphasis on magnetic resonance imaging: pictorial essay / Achados de imagem da periartrite cálcica aguda, com ênfase na ressonância magnética: ensaio iconográfico

Abstract Acute calcific periarthritis (ACP) is defined as periarticular inflammation associated with intra-articular deposits of hydroxyapatite and other basic calcium phosphate crystals. Patients with ACP present with a sudden onset of pain, together with localized swelling, as well as erythema, tenderness, and reduced range of motion. Familiarity with the clinical and radiological manifestations of ACP aids in the diagnosis and helps differentiate it from other conditions, particularly infectious or inflammatory pathologies such as septic arthritis and gout, thereby reducing the number of unnecessary diagnostic and therapeutic procedures. The objective of this pictorial essay is to illustrate the imaging findings of ACP in various joints, with an emphasis on the findings obtained by magnetic resonance imaging.

Resumo A periartrite cálcica aguda (PCA) é uma inflamação periarticular aguda associada a depósitos justa-articulares de hidroxiapatita e outros cristais básicos de fosfato de cálcio. Os pacientes apresentam início súbito de dor, edema localizado, eritema, sensibilidade e redução da amplitude de movimentos. A familiaridade com as manifestações clínicas e radiológicas da PCA facilita o diagnóstico e permite diferenciá-la de outras entidades, em particular, com doenças infecciosas ou inflamatórias, como artrite séptica e gota, reduzindo procedimentos diagnósticos e terapêuticos desnecessários. O objetivo deste ensaio iconográfico é ilustrar os achados de imagem de PCA em algumas articulações, com ênfase na ressonância magnética.

ANALYSIS OF THE TRACKING INITIATIVES OF COLORECTAL CANCER IN BRAZIL.

BACKGROUND: Colorectal cancer (CRC) is an important public health problem, as it represents the world's third most diagnosed neoplasm and the fourth cause of mortality. Its prevention can be divided into primary, secondary, demonstrated by tracking techniques, and tertiary, which consists of cancer diagnosis in symptomatic patients. Despite presenting a high incidence, the mortality rates decreased in the past two decades in developed countries, while the opposite happened in underdeveloped countries. That is attributed to the increase of colorectal cancer tracking programs in developed countries, which allows the precocious diagnosis and treatment of precancerous injuries and CRC. In that manner, the American Cancer Society divides the secondary tracking methods in exams based on feces samples and visual analysis of the colon and rectum, indicating its initiation starting at 45 years old in lower-risk patients. OBJECTIVE: Verify in an analytical way the actions of colorectal cancer tracking held in Brazil, as to evaluate the necessity of implementation of a national tracking program of CRC. METHODS: The methodology was based on a descriptive-quantitative secondary study that correlated the incidence of CRC, its morbidity and mortality, and the impact of the precocious tracking programs. It included activities not reported in medical literature through personal contacts with coordinators of regional programs to compare with the existent data in the literature. It was used as a variable for the tracking strategies the exams held, and their respective results. RESULTS: It described nine programs held in different regions in Brazil, using two screening methods for CRC: a noninvasive method that consists of the research of blood hidden in feces, being the majority through the FIT method, and an invasive method, having the colonoscopy as its representant. These initiatives were effective in the detection of early forms of this disease. CONCLUSION: Despite the existence of several private tracking programs and the broad divulgation of the importance of the tracking and the early diagnosis of colorectal cancer, it was demonstrated that Brazil lacks a national program that patronizes the tracking methods, which reflects in the major prevalence of late diagnosis in the population.

RESUMO Contexto: O câncer colorretal (CCR) é um importante problema de saúde pública, uma vez que representa a terceira neoplasia mais diagnosticada no mundo e a quarta causa de mortalidade. Sua prevenção pode ser dividida em primária, secundária, demonstrada pelas técnicas de rastreamento e terciária, que consiste no diagnóstico de câncer em pacientes sintomáticos. Apesar de apresentar uma alta incidência, as taxas de mortalidade diminuíram nas últimas duas décadas nos países desenvolvidos, enquanto o contrário ocorreu em países subdesenvolvidos, o que atribui-se a elevação dos programas de rastreamento colorretal nesses países, de modo que permite o diagnóstico precoce e o tratamento de lesões pré-cancerosas e do CCR. Desse modo, a American Cancer Society divide os métodos de rastreio secundário em testes baseados em amostras de fezes e exames visuais do cólon e reto, indicando-se seu início a partir dos 45 anos de idade, em pacientes de baixo risco. Objetivo: Verificar de forma analítica as ações de rastreamento do câncer colorretal realizadas no Brasil, de modo a avaliar a necessidade da implementação de um programa nacional de rastreamento do CCR. Métodos: A metodologia baseou-se em um estudo secundário quantitativo descritivo que correlacionou a incidência do CCR e sua morbimortalidade e o impacto dos programas de rastreamento precoce. Foram incluídas atividades não relatadas na literatura médica através de contatos pessoais com coordenadores de programas regionais, de modo a comparar com os dados existentes na literatura. Utilizou-se como variáveis as estratégias de triagem, os exames realizados e seus respectivos resultados. Resultados: Foram descritos nove programas realizados em diversas regiões do Brasil utilizando dois métodos de rastreio para o CCR, um não invasivo que consiste na pesquisa de sangue oculto nas fezes, sendo a maioria pelo método FIT; e outro invasivo, tendo a colonoscopia como representante. Essas iniciativas foram efetivas na detecção de formas precoces desta doença. Conclusão: Apesar da existência de diversos programas de rastreamento de início privativo e a ampla divulgação da importância do rastreamento e diagnóstico precoce do CCR, foi demonstrado que o Brasil carece de um programa nacional que padronize as formas de rastreio, o que reflete na maior prevalência de diagnósticos tardios na população.

Oropouche virus infection induces ROS production and oxidative stress in liver and spleen of mice.

Oropouche virus (OROV) is the aetiological agent of Oropouche fever, the symptoms of which are common to most arboviruses, such as fever, headache, malaise, nausea and vomiting. More than half a million people have been infected with OROV since its isolation in 1955. Although Oropouche fever is classified as a neglected and emerging disease, to date, there are no antiviral drugs or vaccines available against the infection and little is known about its pathogenicity. Therefore, it is essential to elucidate the possible mechanisms involved in its pathogenesis. Since oxidative stress plays a pivotal role in the progression of various viral diseases, in this study, redox homeostasis in the target organs of OROV infection was evaluated using an animal model. Infected BALB/c mice exhibited reduced weight gain, splenomegaly, leukopenia, thrombocytopenia, anaemia, development of anti-OROV neutralizing antibodies, increased liver transaminases, and serum levels of pro-inflammatory cytokines tumour necrosis factor (TNF-α) and interferon-γ (IFN-γ). The OROV genome and infectious particles were detected in the liver and spleen of infected animals, with liver inflammation and an increase in the number and total area of lymphoid nodules in the spleen. In relation to redox homeostasis in the liver and spleen, infection led to an increase in reactive oxygen species (ROS) levels, increased oxidative stress biomarkers malondialdehyde (MDA) and carbonyl protein, and decreased activity of the antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT). Taken together, these results help elucidate some important aspects of OROV infection that may contribute to the pathogenesis of Oropouche.

Endoscopic ultrasound-guided biliary drainage: a literature review.

Neoplasms of the biliopancreatic confluence may present with obstruction of the bile tract, leading to jaundice, pruritus and cholangitis. In these cases drainage of the bile tract is imperative. Endoscopic retrograde cholangiopancreatography (ERCP) with placement of a choledochal prosthesis is an effective treatment in about 90% of cases, even in experienced hands. In cases of ERCP failure, therapeutic options traditionally include surgical bypass by hepaticojejunostomy (HJ) or percutaneous transparietohepatic drainage (DPTH). In recent years, endoscopic ultrasound-guided biliary drainage techniques have gained space because they are less invasive, effective and have an acceptable incidence of complications. Endoscopic echo-guided drainage of the bile duct can be performed through the stomach (hepatogastrostomy), duodenum (choledochoduodenostomy) or by the anterograde drainage technique. Some services consider ultrasound-guided drainage of the bile duct the procedure of choice in the event of ERCP failure. The objective of this review is to present the main types of endoscopic ultrasound-guided biliary drainage and compare them with other techniques.

Gasdermin-D activation promotes NLRP3 activation and host resistance to Leishmania infection.

Intracellular parasites from the Leishmania genus cause Leishmaniasis, a disease affecting millions of people worldwide. NLRP3 inflammasome is key for disease outcome, but the molecular mechanisms upstream of the inflammasome activation are still unclear. Here, we demonstrate that despite the absence of pyroptosis, Gasdermin-D (GSDMD) is active at the early stages of Leishmania infection in macrophages, allowing transient cell permeabilization, potassium efflux, and NLRP3 inflammasome activation. Further, GSDMD is processed into a non-canonical 25 kDa fragment. Gsdmd-/- macrophages and mice exhibit less NLRP3 inflammasome activation and are highly susceptible to infection by several Leishmania species, confirming the role of GSDMD for inflammasome-mediated host resistance. Active NLRP3 inflammasome and GSDMD are present in skin biopsies of patients, demonstrating activation of this pathway in human leishmaniasis. Altogether, our findings reveal that Leishmania subverts the normal functions of GSDMD, an important molecule to promote inflammasome activation and immunity in Leishmaniasis.

CASP4/11 Contributes to NLRP3 Activation and COVID-19 Exacerbation.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection triggers activation of the NLRP3 inflammasome, which promotes inflammation and aggravates severe COVID-19. Here, we report that SARS-CoV-2 induces upregulation and activation of human caspase-4/CASP4 (mouse caspase-11/CASP11), and this process contributes to NLRP3 activation. In vivo infections performed in transgenic hACE2 humanized mice, deficient or sufficient for Casp11, indicate that hACE2 Casp11-/- mice were protected from disease development, with the increased pulmonary parenchymal area, reduced clinical score of the disease, and reduced mortality. Assessing human samples from fatal cases of COVID-19, we found that CASP4 was expressed in patient lungs and correlated with the expression of inflammasome components and inflammatory mediators, including CASP1, IL1B, IL18, and IL6. Collectively, our data establish that CASP4/11 promotes NLRP3 activation and disease pathology, revealing a possible target for therapeutic interventions for COVID-19.

Implementation of a digital tool for population management in Primary Health Care / Implementação de ferramenta digital para gestão populacional na atenção primária à saúde

ABSTRACT OBJECTIVE Describe the implementation of a digital diagnostic and territorial monitoring tool in primary healthcare. METHODS Quantitative and qualitative study, developed in 14 basic healthcare units in São Paulo, with community health workers, coordinators, nurses, and physicians. Data collection occurred in four phases: analysis of the instruments used by the team for territory management; development of the digital tool; training and implementation; and evaluation after 90 days using focus groups. Descriptive analyses were conducted by calculating absolute and relative frequencies to treat quantitative data. Qualitative data were subjected to content analysis. RESULTS Three hundred thirty-four professionals participated in the study. In the first step, territory management's main challenges were filling out various instruments, system failures, data inconsistency, internet infrastructure/network, and lack of time. Therefore, a digital tool was developed consisting of 1) a spreadsheet recording the number of family members and markers of health conditions, date of visit, and number of return visits; 2) a spreadsheet with a summary of families visited, not visited, and refusals; and 3) a panel with a summary of the data generated instantly. In the evaluation, after the initial use of the tool, the themes that emerged were integration of the tool into daily work, evaluation of the digital tool implementation process, and improvement and opportunities for improvement. CONCLUSIONS Faced with the challenges faced by family healthcare teams when filling out systems and managing the territory, the tool developed provided greater reliability and agility in data visualization, reduced the volume of instruments, and optimized the work process.

Na avaliação, após uso inicial da ferramenta, as temáticas que emergiram foram: integração da ferramenta no cotidiano de trabalho; avaliação do processo de implementação da ferramenta digital; aperfeiçoamento e oportunidades de melhoria. CONCLUSÃO Frente aos desafios encontrados por parte das equipes de saúde da família para preenchimento dos sistemas e gestão do território, a ferramenta desenvolvida proporcionou maior fidedignidade e agilidade na visualização dos dados, redução no volume de instrumentos e otimização do processo de trabalho.

The knowledge of primary health care professionals regarding mental health: diagnosis by mhGAP / Conhecimento de profissionais da atenção primária em saúde mental: diagnóstico pelo mhGAP

ABSTRACT OBJECTIVE To analyze knowledge about priority topics in mental health care of strategic actors who work in regions where the Health Care Planning (PAS) methodology is used. METHODS This is a quantitative, descriptive, cross-sectional, and observational study carried out with professionals from six health regions, distributed in three Brazilian states (Goiás, Rondônia and Maranhão) and linked to the project "Saúde mental na APS" (Mental health in PHC) of the Programa de Apoio ao Desenvolvimento Institucional do Sistema Único de Saúde (Proadi-SUS - Institutional Development Support Program of the Brazilian Unified Health System). The sample was made up of professionals who participated in the intervention guide multiplier training stage for mental, neurological and alcohol and other drug use disorders in the primary health care network, from July to September 2022. Data collection was through a self-administered instrument, in electronic format, consisting of a block with socioeconomic items and a structured questionnaire to assess participants' knowledge about priority topics in mental health. Descriptive analyses and comparison of proportions were conducted to analyze the data. RESULTS A total of 354 health professionals participated in the study. Regarding the percentage of correct answers in the questionnaire on priority topics in mental health, the highest medians were identified in the "Depression" module. On the other hand, the content referring to the modules "Essential care and practices" and "Other important complaints" presented the lowest values. Furthermore, some participant characteristics were found to be associated with the percentage of correct answers in the questionnaire modules. CONCLUSIONS The findings reveal opportunities for improvement, mainly in knowledge related to communication skills and the approach to emotional and physical distress without diagnostic criteria for a specific disease, offering support for planning actions aimed at intensifying the consideration of these themes during the operational stages of PAS.

RESUMO OBJETIVO Analisar o conhecimento sobre temas prioritários do cuidado em saúde mental de atores estratégicos que atuam em regiões nas quais se utiliza a metodologia da Planificação da Atenção à Saúde (PAS). MÉTODOS Trata-se de um estudo quantitativo, descritivo, transversal e observacional realizado com profissionais de seis regiões de saúde, distribuídas em três estados brasileiros (Goiás, Rondônia e Maranhão) e vinculadas ao projeto "Saúde mental na APS" do Programa de Apoio ao Desenvolvimento Institucional do Sistema Único de Saúde (Proadi-SUS). A amostra foi composta por profissionais que participaram da etapa de formação de multiplicadores do manual de intervenções para transtornos mentais, neurológicos e por uso de álcool e outras drogas na rede de atenção básica à saúde, no período de julho a setembro de 2022. A coleta de dados foi realizada a partir de um instrumento autoaplicável, em formato eletrônico, composto por um bloco com itens socioeconômicos e um questionário estruturado para avaliação do conhecimento dos participantes acerca de temas prioritários em saúde mental. Para análise dos dados, foram empreendidas análises descritivas e comparação de proporções. RESULTADOS Participaram do estudo 354 profissionais de saúde. Em relação ao percentual de acerto no questionário sobre temas prioritários em saúde mental, as medianas mais altas foram identificadas no módulo de "Depressão". Em contrapartida, o conteúdo referente aos módulos "Cuidados e práticas essenciais" e "Outras queixas importantes" apresentaram os valores mais baixos. Além disso, identificou-se que algumas características dos participantes apresentaram associações com o percentual de acertos nos módulos do questionário. CONCLUSÕES Os achados revelam oportunidades de melhoria, principalmente no conhecimento relacionado às habilidades de comunicação e a abordagem ao sofrimento emocional e físico sem critérios diagnósticos para uma doença específica, oferecendo subsídios para o planejamento de ações que visem a intensificação do olhar destas temáticas durante as etapas operacionais da PAS.

Brazilian Scale for Evaluation of Mental Health Care Needs: Additional Evidence / Escala de Avaliação da Necessidade de Cuidado em Saúde Mental: evidências adicionais

ABSTRACT OBJECTIVE To investigate validity evidence of the Brazilian Scale for Evaluation of Mental Health Care Needs (CuidaSM). METHODS This is a psychometric study, which seeks additional evidence of internal structure. Data collection was carried out in 11 Primary Health Care (PHC) services , which implement the Health Care Planning (HCP) methodology, distributed across the five Brazilian regions. The preliminary version of CuidaSM, containing a block self-referred by the user and another block evaluated by PHC professionals, was applied to users aged 18 or over who attended the PHC services for consultation with a higher education professional. The techniques of confirmatory factor analysis and network analysis were used to investigate validity evidence. For the primary data of the confirmatory factor analysis, the factorial loads and the item's predictive power (R2) were used. Six model adjustment indices were adopted and reliability was measured by three indicators using Bayesian estimation. RESULTS A total of 879 users participated in the study. By confirmatory factor analysis, factorial loads ranged from 0.43 to 0.99 and R2 from 0.19 to 0.98. Both the primary indicators and the model adequacy indices were established at satisfactory and consistent levels. The network analysis showed that the items were appropriately associated with their peers, respecting the established dimensions, which again indicates the sustainability and stability of the proposed model. CONCLUSIONS The study findings confirm a consistent and reliable model of the instrument, through a combination of techniques. Considering the importance of using solid instruments in clinical practice, CuidaSM is a promising tool for population-based management and network care organization, aligned with HCP proposals.

MÉTODOS Trata-se de um estudo de natureza psicométrica, que busca evidências adicionais de estrutura interna. A coleta de dados foi realizada em 11 unidades básicas de saúde (UBS), que executam a metodologia da Planificação da Atenção à Saúde (PAS), distribuídas nas cinco regiões brasileiras. A versão preliminar da CuidaSM, contendo um bloco autorreferido pelo usuário e outro avaliado por profissionais da atenção primária à saúde (APS), foi aplicada em usuários com 18 anos ou mais que compareceram às UBS para consulta com profissional de nível superior. As técnicas de análise fatorial confirmatória e network analysis foram utilizadas para investigação das evidências de validade. Para os dados primários da análise fatorial confirmatória, utilizou-se as cargas fatoriais e o poder preditivo do item (R2). Foram adotados seis índices de ajustamento do modelo e a confiabilidade foi aferida por três indicadores por meio de bayesian estimation. RESULTADOS Participaram do estudo 879 usuários. Pela análise fatorial confirmatória, as cargas fatoriais variaram de 0,43 a 0,99 e R2 de 0,19 a 0,98. Tanto os indicadores primários como os índices de adequação do modelo estabeleceram-se em níveis satisfatórios e consistentes. A network analysis apontou que os itens se associaram de forma adequada a seus pares, respeitando as dimensões estabelecidas, o que indica, novamente, a sustentabilidade e estabilidade do modelo proposto. CONCLUSÕES Os achados do estudo confirmam um modelo consistente e confiável do instrumento, por meio da combinação de técnicas. Considerando a relevância do uso de instrumentos sólidos na prática clínica, a CuidaSM se apresenta como uma ferramenta promissora para a gestão de base populacional e organização do cuidado em rede, alinhada às propostas da PAS.

Endoscopic ultrasound-guided biliary drainage: a literature review / Drenagem biliar endoscópica ecoguiada: revisão da literatura

RESUMO Neoplasias da confluência biliopancreática podem cursar com obstrução da via biliar, levando a icterícia, prurido e colangite. Nesses casos a drenagem da via biliar é imperativa. A colangiopancreatografia endoscópica retrógrada (CPER) com colocação de prótese coledociana constitui tratamento eficaz em cerca de 90% dos casos mesmo em mãos experientes. Nos casos de insucesso da CPER, tradicionalmente as opções terapêuticas incluem a derivação cirúrgica por hepaticojejunostomia (HJ) ou drenagem percutânea transparietohepática (DPTH). Nos últimos anos as técnicas endoscópicas ecoguiadas de drenagem biliar ganharam espaço por serem menos invasivas, eficazes e apresentarem incidência aceitável de complicações. A drenagem endoscópica ecoguiada da via biliar pode ser realizada pelo estômago (hepatogastrostomia), duodeno (coledocoduodenostomia) ou pela técnica de drenagem anterógrada. Alguns serviços consideram a drenagem ecoguiada da via biliar o procedimento de escolha no caso de insucesso da CPER. O objetivo desta revisão é apresentar os principais tipos de drenagem biliar endoscópica ecoguiada e confrontá-los com outras técnicas.

Reconstrução escrotal após gangrena de Fournier / Scrotal reconstruction after Fournier's gangrene

Introdução: Gangrena de Fournier é uma infecção polibacteriana, geralmente causada por bactérias anaeróbias e aeróbias, sendo caracterizada por fasciite necrosante escrotal e perineal. Seu tratamento é embasado em intervenção cirúrgica com excisão da área necrótica e antibioticoterapia precoces. Diversas são as estratégias de reconstrução do defeito resultante do desbridamento, devendo ser salientado que perdas teciduais maiores do que 50% costumam ser reconstruídas com retalhos. Métodos: Análise retrospectiva da série de casos de reconstrução escrotal após gangrena de Fournier procedidos pelos autores ao longo de 2020, totalizando oito pacientes. Resultados: O retalho mais utilizado foi o fasciocutâneo de coxa, que apresentou taxa de necrose parcial de 14,29%, sem necrose total. Em um dos casos foi possível reconstruir uma uretra esponjosa com músculo grácil sem fistulização, evitando que o paciente fosse submetido a uma uretrostomia definitiva. Quanto às complicações, foi comum a ocorrência de intercorrências menores que necessitaram de procedimentos revisionais simples. Destaca-se a prevalência de 75% de diabetes mellitus em nossa casuística, o que pode ter interferido negativamente no processo cicatricial. Conclusão: A reconstrução escrotal com retalhos é importante para acelerar a cicatrização da ferida proveniente do desbridamento de gangrena de Fournier e para manter o aspecto de bolsa necessário para a termorregulação do testículo. Nossa opção primária foi o retalho fasciocutâneo de coxa, que se mostrou seguro. Pequenas intercorrências foram frequentes nesta série, sem comprometimento do resultado final.

Introduction: Fournier's gangrene is a polybacterial infection, usually caused by anaerobic and aerobic bacteria, characterized by scrotal and perineal necrotizing fasciitis. Its treatment is based on surgical intervention by excision of the necrotic area and early antibiotic therapy. There are several strategies to reconstruct the defect resulting from debridement, and it should be noted that tissue losses greater than 50% are usually reconstructed with flaps. Methods: Retrospective analysis of the series of cases of scrotal reconstruction after Fournier's gangrene performed by the authors throughout 2020, totaling eight patients. Results: The most used flap was thigh fasciocutaneous flap, which presented a partial necrosis rate of 14.29%, without total necrosis. In one of the cases, it was possible to reconstruct a spongy urethra with gracilis muscle without fistulization, preventing the patient from undergoing a definitive urethrostomy. As for complications, the occurrence of minor complications that required simple revision procedures was common. The prevalence of 75% of diabetes mellitus in our series is highlighted, which may have negatively interfered with the healing process. Conclusion: Scrotal reconstruction with flaps is important to accelerate wound healing from Fournier gangrene debridement and to maintain the pouch aspect necessary for testicular thermoregulation. Our primary option was thigh fasciocutaneous flap, which proved to be safe. And minor complications were frequent in this series, without compromising the final result.

Efferocytosis of SARS-CoV-2-infected dying cells impairs macrophage anti-inflammatory functions and clearance of apoptotic cells.

COVID-19 is a disease of dysfunctional immune responses, but the mechanisms triggering immunopathogenesis are not established. The functional plasticity of macrophages allows this cell type to promote pathogen elimination and inflammation or suppress inflammation and promote tissue remodeling and injury repair. During an infection, the clearance of dead and dying cells, a process named efferocytosis, can modulate the interplay between these contrasting functions. Here, we show that engulfment of SARS-CoV-2-infected apoptotic cells exacerbates inflammatory cytokine production, inhibits the expression of efferocytic receptors, and impairs continual efferocytosis by macrophages. We also provide evidence supporting that lung monocytes and macrophages from severe COVID-19 patients have compromised efferocytic capacity. Our findings reveal that dysfunctional efferocytosis of SARS-CoV-2-infected cell corpses suppresses macrophage anti-inflammation and efficient tissue repair programs and provides mechanistic insights for the excessive production of pro-inflammatory cytokines and accumulation of tissue damage associated with COVID-19 immunopathogenesis.

Functional Study of Leishmania braziliensis Protein Arginine Methyltransferases (PRMTs) Reveals That PRMT1 and PRMT5 Are Required for Macrophage Infection.

In trypanosomatids, regulation of gene expression occurs mainly at the posttranscriptional level, and RNA-binding proteins (RBPs) are key players in determining the fates of transcripts. RBPs are targets of protein arginine methyltransferases (PRMTs), which posttranslationally regulate the RNA-binding capacity and other RBP interactions by transferring methyl groups to arginine residues (R-methylation). Herein, we functionally characterized the five predicted PRMTs in Leishmania braziliensis by gene knockout and endogenous protein HA tagging using CRISPR/Cas9 gene editing. We report that R-methylation profiles vary among Leishmania species and across L. braziliensis lifecycle stages, with the peak PRMT expression occurring in promastigotes. A list of PRMT-interacting proteins was obtained in a single coimmunoprecipitation assay using HA-tagged PRMTs, suggesting a network of putative targets of PRMTs and cooperation between the R-methylation writers. Knockout of each L. braziliensis PRMT led to significant changes in global arginine methylation patterns without affecting cell viability. Deletion of either PRMT1 or PRMT3 disrupted most type I PRMT activity, resulting in a global increase in monomethyl arginine levels. Finally, we demonstrate that L. braziliensis PRMT1 and PRMT5 are required for efficient macrophage infection in vitro, and for axenic amastigote proliferation. The results indicate that R-methylation is modulated across lifecycle stages in L. braziliensis and show possible functional overlap and cooperation among the different PRMTs in targeting proteins. Overall, our data suggest important regulatory roles of these proteins throughout the L. braziliensis life cycle, showing that arginine methylation is important for parasite-host cell interactions.

Cartilaginous choristoma on the lateral surface of the tongue: a case report.

A cartilaginous choristoma is a nonneoplastic nodular growth of histologically normal cartilage in an abnormal site. This report describes a case of a cartilaginous choristoma on the lateral surface of the tongue in a 65-year-old woman. The entire lesion was excised, and histologic examination revealed mature cartilaginous tissue surrounded by dense connective tissue. Choristomas are rare findings in the oral cavity, easily confused with proliferative processes or soft tissue neoplasms. Nevertheless, choristomas may be part of the differential diagnosis for lesions similar to the one described in this case report.

Implementation of the drive-through strategy for COVID-19 vaccination: an experience report / Implementación de la estrategia drive-through para la vacunación contra el COVID-19: relato de experiencia / Implementação da estratégia drive-through para vacinação COVID-19: um relato de experiência

Abstract Objective: To describe the experience of implementing a satellite vaccination unit in a drive-through system during a campaign against COVID-19. Method: This is an experience report carried out in a drive-through vaccination satellite unit. The study development was guided by the triad structure-process-results, proposed by Donabedian. Results: The unit was structured in a soccer stadium, allowing it to serve large audiences safely. Care flow occurred in stages and professionals were organized by sectors, with emphasis on the nursing team' work. Initially, screening was performed; later, users went to the registration sector, and, finally, they were forwarded to the application station. The unit also had emergency sectors, a cold chain, space for professionals and a Basic Health Unit as a point of support. In 25 days of operation, 9698 doses were administered, with 1.8% of doses lost. Conclusion: The implementation of this system required planning, structure, process development and intense team articulation, with emphasis on the fundamental and strategic role of nurses in different points of action and leadership.
