Abstract Background: Only a fraction of patients with cutaneous lupus erythematosus (CLE) will eventually progress toward systemic disease (SLE). Objective: To find inflammatory biomarkers which could predict the progression of cutaneous lupus erythematosus (CLE) into systemic lupus erythematosus (SLE) using immunohistochemical (IHC) assays. Methods: Immunohistochemical markers for cytotoxic, inflammatory, and anti-inflammatory responses and morphometric methods were applied to routine paraffin sections of skin biopsies, taken from lesions of 59 patients with discoid lupus, subacute lupus, and lupus tumidus. For the diagnosis of SLE, patients were classified by both the American College of Rheumatology (ACR-82) and the Systemic Lupus International Collaborating Clinics (SLICC-12) systems. Results: Skin samples from CLE/SLE +patients presented higher expression of IL-1β (ARC-82: p = 0.024; SLICC-12: p = 0.0143) and a significantly higher number of cells marked with granzyme B and perforin (ARC: p = 0.0097; SLICC-12: p = 0.0148). Biopsies from CLE/SLE- individuals had higher expression of IL-17 (ARC-82: p = 0.0003; SLICC-12: p = 0.0351) and presented a positive correlation between the density of granzyme A+and FoxP3+ cells (ARC-82: p = 0.0257; SLICC-12: p = 0.0285) and CD8+ cells (ARC-82: p = 0.0075; SLICC-12: p = 0.0102), as well as between granulysin-positive and CD8+ cells (ARC-82: p = 0.0024; SLICC-12: p = 0.0116). Study limitations: Patients were evaluated at a specific point in their evolution and according to the presence or not of systemic disease. The authors cannot predict how many more, from each group, would have evolved towards SLE in the following years. Conclusions: In this cohort, immunohistochemical findings suggested that patients with a tendency to systemic disease will show strong reactivity for IL-1β, while those with purely cutaneous involvement will tend to express IL-17 more intensely.

Abstract Studies investigating the effects of different modalities of exercises on the immune system are scarce. Therefore, the aim of this study was to compare the effects of eight weeks of resistance and aerobic training on the proliferation of T and B lymphocytes from mice. Eighteen male C56BL6/J mice were divided into groups (n=6), sedentary, aerobic, and resistance training. After 8 weeks, animals were euthanized, and their splenocytes were labeled and cultured with and without stimulation. Lymphocyte proliferation (CD4+, CD8+ and CD21/CD35+) was evaluated by flow cytometry. The mice subjected to resistance exercise exhibited greater proliferation for total, CD8+ and B lymphocytes (p<0.05), but not CD4+ cells (p>0.05), compared with their sedentary counterparts. We found significant correlations between maximum load and total, CD8+ and B lymphocytes proliferation rates (p<0.05). In conclusion, our results showed that resistance training promoted an improvement in the immune response associated with CD8+ and B lymphocytes.

SUMMARY OBJECTIVE: The aim of this study was to evaluate the prevalence of early neonatal sepsis in pregnant women with a positive culture for group B beta-hemolytic Streptococcus in a middle-income city in Southeastern Brazil. METHODS: A retrospective cohort study was conducted, involving singleton low- and high-risk pregnancies in whom group B beta-hemolytic Streptococcus cultures were evaluated between 35 and 37 weeks of gestation using vaginal and anal swabs. A specific medium (Todd-Hewitt) was used for culturing. The pregnant women were divided into two groups based on positive (n==201) and negative (n==420) cultures for group B beta-hemolytic Streptococcus. RESULTS: The maternal colonization rate by group B beta-hemolytic Streptococcus was 32.3%. The prevalence of early neonatal sepsis was 1.0% (2/201) among patients with a positive group B beta-hemolytic Streptococcus culture and 1.9% (8/420) among patients with a negative culture. Among the patients who underwent adequate prophylaxis, crystalline penicillin G was used in 51.9% (54/104), followed by cefazolin in 43.3% (45/104), ampicillin in 3.8% (4/104), and clindamycin in 1.0% (1/104). A model that included prematurity (p==0.001) proved to be an independent risk predictor of early neonatal sepsis [χ2 (1)==15.0, odds ratio: 16.9, 95% confidence interval: 4.7–61.6, p<0.001, Nagelkerke R2==0.157]. CONCLUSION: The prevalence of a positive culture for group B beta-hemolytic Streptococcus was high. However, the prevalence of early neonatal sepsis was low in pregnant women with both positive and negative group B beta-hemolytic Streptococcus cultures and in pregnant women with a positive culture who underwent both adequate and inadequate antibiotic prophylaxis. Prematurity proved to be an independent predictor of early neonatal sepsis, considering the entire study population.

ABSTRACT Objective: The aim of this study was to analyze the temporal trends in vaccination coverage (VC) during the first year of life of children in Brazil. Methods: Data on VC for the first year of life from 2011 to 2020 for Bacille Calmette-Guerin (BCG), hepatitis B, polio, pentavalent, and triple viral vaccines at the national, regional, and state levels were obtained from the Information System of the National Immunization Program. Trends were analyzed using Prais-Winsten generalized linear regression models and average annual percent change (APC) estimates. Results: Decreasing trends were observed for the BCG (APC −3.58%; p<0.05), pentavalent (APC −4.10%; p<0.05), polio (APC −2.76%; p<0.05), and triple viral (APC −2.56%; p<0.05) vaccines in the country. Hepatitis B vaccine was the only vaccine that displayed stationary behavior (APC −4.22%; p>0.05). During the study period, no increasing trends were observed in any territory or vaccine. Conclusions: This study shows a recent significant reduction and decreasing trends in VC during the first year of life of children in Brazil, indicating the need for interventions to curb this ongoing phenomenon and to recover acceptable VC rates in the country.

RESUMO Objetivo: Analisar a tendência temporal da cobertura vacinal (CV) em crianças com idade menor ou igual a um ano no Brasil. Métodos: Foram empregados dados da CV no primeiro ano de vida de 2011 a 2020 referentes às vacinas BCG, hepatite B, poliomielite, pentavalente e tríplice viral, obtidos do Sistema de Informação do Programa Nacional de Imunizações (SI-PNI). Os dados estão agregados em nível nacional, regional e estadual. Para a análise de tendência foi utilizado o modelo de regressão linear generalizado de Prais-Winsten e foi calculada a variação percentual média anual (APC). Resultados: As tendências de CV para as vacinas BCG (APC −3,58%; p<0,05), pentavalente (APC −4,10%; p<0,05), poliomielite (APC −2,76%; p<0,05) e tríplice viral (APC −2,56%; p<0,05) foram decrescentes no país. Apenas para a CV da vacina contra hepatite B foi identificado comportamento estacionário (APC −4,22%; p>0,05). Nenhum território ou vacina apresentou tendência crescente para cobertura vacinal no período estudado no Brasil. Conclusões: Este estudo alerta sobre a redução expressiva das CV no primeiro ano de vida nos últimos anos no Brasil e sua tendência decrescente, sendo imperativa a adoção de intervenções com o fim de frear o fenômeno em curso e de resgatar níveis aceitáveis de CV no país.

Abstract Objective: to analyze nursing technicians’ training in patient safety. Method: a convergent parallel mixed-methods study, where qualitative and quantitative elements were concomitantly implemented and equally prioritized, carried out in three technical colleges linked to a federal public institution in the Brazilian Northeast region. In the qualitative phase, semi-structured interviews were conducted with 24 professors and thematic analysis was applied. In the quantitative study, of the survey type, an instrument was used to screen terms about patient safety with 84 students. The results were combined during the general data interpretation, which was based on the Patient Safety Curricular Guide. Results: two thematic categories emerged: The professors’ understanding about the theme of patient safety in nursing technicians’ training; and Application and projection of the teaching of patient safety in nursing technicians’ training. In the quantitative study, among the 46 screening terms, their identification in the theoretical-practical context predominated in Courses A and C, totaling 36 (78.3%) and 25 (54.3%), respectively. Theoretical teaching stood out in Course B, with 26 terms (56.5%). Conclusion: professional training of Nursing Technician students has a technical focus and does not fully contemplate patient safety issues in the teaching-learning process and, thus, constitutes a challenge for training institutions and professors alike.

Resumen Objetivo: analizar la formación de los técnicos en enfermería en seguridad del paciente. Método: estudio de método mixto paralelo convergente, en el que los elementos cualitativos y cuantitativos fueron implementados simultáneamente y considerados con el mismo nivel de prioridad, realizado en tres escuelas técnicas vinculadas a una institución pública federal en el Nordeste brasileño. En el estudio cualitativo se realizó una entrevista semiestructurada a 24 profesores y se aplicó el análisis temático. En el estudio cuantitativo, survey, se utilizó un instrumento para detectar términos sobre seguridad del paciente con 84 estudiantes. Para la interpretación general de los datos se realizó la combinación de los resultados y se tomó como base la Guía Curricular de Seguridad del Paciente. Resultados: surgieron dos categorías temáticas: Comprensión de los docentes sobre la seguridad del paciente en la formación de técnicos en enfermería e Implementación y proyección de la enseñanza de la seguridad del paciente en la formación de técnicos en enfermería. En el estudio cuantitativo, en los 46 términos indicadores, predominó la identificación de términos en el contexto teórico-práctico, en las carreras A y C, con un total de 36 (78,3%) y 25 (54,3%), respectivamente. En la carrera B se destacó la enseñanza teórica, con 26 términos (56,5%). Conclusión: la formación profesional de los estudiantes de la carrera de técnico en enfermería tiene un enfoque técnico y no considera de forma integral los temas que tienen que ver con la seguridad del paciente en el proceso de enseñanza-aprendizaje, por lo que es un desafío para las instituciones formadoras y para los docentes.

No qualitativo, realizou-se entrevista semiestruturada com 24 docentes e aplicou-se a análise temática. No estudo quantitativo, survey, utilizou-se instrumento para rastrear termos sobre segurança do paciente com 84 discentes. A interpretação geral dos dados realizou a combinação dos resultados e balizou-se no Guia Curricular de Segurança do Paciente. Resultados: emergiram duas categorias temáticas: Compreensão dos docentes acerca do tema segurança do paciente na formação de técnicos de enfermagem e Aplicação e projeção do ensino da segurança do paciente na formação de técnicos de enfermagem. No estudo quantitativo, dos 46 termos rastreadores, predominou a identificação de termos no contexto teórico-prático, nos Cursos A e C, totalizando 36 (78,3%) e 25 (54,3%), respectivamente. No Curso B, destacou-se ensino teórico, com 26 termos (56,5%). Conclusão: a formação profissional do discente técnico de enfermagem apresenta foco tecnicista e não contempla, integralmente, no processo ensino-aprendizagem, questões de segurança do paciente e, assim, configura-se desafio para as instituições formadoras e docentes.

Resumo: O estudo investiga os aspectos epidemiológicos da hepatite B em crianças e adolescentes, discutindo os resultados encontrados à luz dos princípios da bioética. Trata-se de um estudo transversal, retrospectivo, com base em uma série temporal de casos, cujos dados de notificação foram extraídos do Sistema de Informação de Agravos de Notificação (SINAN) e dados de vacinação do Sistema de Informação do Programa Nacional de Imunizações - SIPNI, no período de 2011 a 2020. Foram notificados 889 casos de hepatite B na população de estudo. A maioria dos participantes encontravam-se na faixa etária de 15 a 19 anos 738 (83%), do sexo feminino 549 (62%), cor da pele parda 637 (72%) residentes na zona urbana 490 (55%) e com ensino fundamental incompleto 279 (31%). A provável fonte de infecção foi por via sexual 450 (51%). A forma clínica mais comum foi a Hepatite Crônica 496 (56%). A maioria dos contaminados com Hepatite B foram indivíduos não vacinados 298 (34%). A luz da bioética os resultados demostram que a prática da vacinação pode contemplar os princípios bioéticos, já que o grau de autonomia depende de um tipo de intervenção planejada e quanto maior a relação entre benefício e ônus, tendo em conta os princípios de beneficência e não maleficência, menos decisiva é essa autonomia.

Resumen: El estudio investiga los aspectos epidemiológicos de la hepatitis B en niños y adolescentes, discutiendo los resultados encontrados a la luz de los principios bioéticos. Se trata de un estudio transversal, retrospectivo, basado en una serie temporal de casos, cuyos datos de notificación fueron extraídos del Sistema de Información de Enfermedades de Declaración Obligatoria (SINAN) y datos de vacunación del Sistema de Información del Programa Nacional de Inmunizaciones SIPNI, desde 2011 hasta 2020. Se informaron 889 casos de hepatitis B en la población de estudio. La mayoría de los participantes tenían entre 15 y 19 años 738 (83 %), sexo femenino 549 (62 %), color de piel morena 637 (72 %), residentes en zona urbana 490 (55 ) y con educación primaria incompleta 279 (31 %). La fuente probable de infección fue a través de relaciones sexuales 450 (51%). La forma clínica más frecuente fue la Hepatitis Crónica 496 (56%). La mayoría de los infectados con Hepatitis B eran individuos no vacunados 298 (34%). A la luz de la bioética, los resultados muestran que la práctica de la vacunación puede contemplar principios bioéticos, ya que el grado de autonomía depende de un tipo de intervención planificada y mayor la relación entre beneficio y carga, teniendo en cuenta los principios de beneficencia y no maleficencia, menos decisiva es esta autonomía.

Abstract: The study investigates the epidemiological aspects of hepatitis B in children and adolescents, discussing the results found in the light of bioethical principles. This is a cross-sectional, retrospective study, based on a time series of cases, whose notification data were extracted from the Notifiable Diseases Information System (SINAN) and vaccination data from the National Immunization Program Information System SIPNI, from 2011 to 2020. 889 cases of hepatitis B were reported in the study population. Most participants were aged between 15 and 19 years old 738 (83%), female 549 (62%), brown skin color 637 (72%) living in the urban area 490 (55%) and with incomplete elementary education 279 (31%). The probable source of infection was through sexual intercourse 450 (51%). The most common clinical form was Chronic Hepatitis 496 (56%). Most of those infected with Hepatitis B were unvaccinated individuals 298 (34%). In the light of bioethics, the results show that the practice of vaccination can contemplate bioethical principles, since the degree of autonomy depends on a type of planned intervention and the greater the relationship between benefit and burden, taking into account the principles of beneficence and not maleficence, the less decisive is this autonomy.

Resumo: O presente estudo trata-se de uma análise na literatura sobre o aspecto bioético da autonomia em relação a imunização contra Hepatite B e HPV na adolescência. Foi realizada uma revisão bibliográfica baseada no método prisma onde foram incluídos artigos em português e inglês os quais foram pesquisados nas plataformas Scientific Electronic Library Online (SciELO), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) e National Library of Medicine (PUBMED), utilizando os seguintes descritores Hepatitis B Vaccines, bioethics, Humans. Os resultados demostraram a eficiência dos profissionais de saúde no contato com o indivíduo e o convencimento deste através de um diálogo aberto e criação de vínculos. Evidenciou-se ainda o estudo evidenciou o direito a autonomia progressiva do paciente, no qual este ganha o direito a algumas escolhas como as imunizações de doenças sexualmente transmissíveis, como é o caso da Hepatite B e HPV, no entanto é necessário que o adolescente seja instruído sobre a imunização. Assim sendo, reconhece-se o direito a autonomia progressiva do adolescente, referente a escolha das imunizações contra a Hepatite B e HPV, entretanto, deve-se considerar que estes indivíduos sejam instruídos sobre os benefícios individuais e/ou coletivos da vacinação, contemplados por atividades de educação em saúde por profissionais qualificados, objetivando ampliar a cobertura global de imunização com doenças que caracterizam problemas de saúde pública.

Resumen: El presente estudio es un análisis de la literatura sobre el aspecto bioético de la autonomía en relación con la inmunización contra la Hepatitis B y el VPH en la adolescencia. Se realizó una revisión bibliográfica basada en el método del prisma, que incluyó artículos en portugués e inglés que fueron buscados en la Biblioteca Científica Electrónica en Línea (SciELO), Literatura Latinoamericana y del Caribe en Ciencias de la Salud (LILACS) y la Biblioteca Nacional de Medicina (PUBMED), utilizando los siguientes descriptores Vacunas Hepatitis B, bioética, Humanos. Los resultados demostraron la eficiencia de los profesionales de la salud en contactar al individuo y convencerlo a través de un diálogo abierto y creación de vínculos. También se evidenció que el estudio evidenció el derecho del paciente a la autonomía progresiva, en la que adquiere el derecho a algunas opciones como las inmunizaciones de enfermedades de transmisión sexual, como la Hepatitis B y el VPH, sin embargo, es necesario que el adolescente sea educado sobre la inmunización. Por lo tanto, se reconoce el derecho del adolescente a la autonomía progresiva, en cuanto a la elección de las vacunas contra la Hepatitis B y el VPH, sin embargo, se debe considerar que estos individuos sean educados sobre los beneficios individuales y/o colectivos de la vacunación, contemplados por las actividades de educación en salud por profesionales calificados, con el objetivo de ampliar la cobertura mundial de inmunización con enfermedades que caracterizan los problemas de salud pública.

Abstract: The present study is an analysis of the literature on the bioethical aspect of autonomy in relation to immunization against Hepatitis B and HPV in adolescence. A bibliographic review was carried out based on the prism method, which included articles in Portuguese and English which were searched on the Scientific Electronic Library Online (SCIELO), Latin American and Caribbean Literature on Health Sciences (LILACS) and the National Library of Medicine (PUBMED), using the following descriptors Hepatitis B Vaccines, bioethics, Humans. The results demonstrated the efficiency of health professionals in contacting the individual and convincing him/her through an open dialogue and creation of bonds. It was also evidenced the study evidenced the patient’s right to progressive autonomy, in which he gains the right to some choices such as immunizations of sexually transmitted diseases, such as Hepatitis B and HPV, however it is necessary for the adolescent to be educated about immunization. Therefore, the adolescent’s right to progressive autonomy is recognized, regarding the choice of immunizations against Hepatitis B and HPV, however, it must be considered that these individuals are instructed on the individual and/or collective benefits of vaccination, contemplated by health education activities by qualified professionals, aiming to expand the global coverage of immunization with diseases that characterize public health problems.

ABSTRACT Objectives: To validate the homeostasis model assessment (HOMA) of insulin resistance (IR) as a surrogate to the hyperglycemic clamp to measure IR in both pubertal and postpubertal adolescents, and determine the HOMA-IR cutoff values for detecting IR in both pubertal stages. Subjects and methods: The study sample comprised 80 adolescents of both sexes (aged 10-18 years; 37 pubertal), in which IR was assessed with the HOMA-IR and the hyperglycemic clamp. Results: In the multivariable linear regression analysis, adjusted for sex, age, and waist circumference, the HOMA-IR was independently and negatively associated with the clamp-derived insulin sensitivity index in both pubertal (unstandardized coefficient – B = −0.087, 95% confidence interval [CI] = −0.135 to −0.040) and postpubertal (B = −0.101, 95% CI, −0.145 to −0.058) adolescents. Bland-Altman plots showed agreement between the predicted insulin sensitivity index and measured clamp-derived insulin sensitivity index in both pubertal stages (mean = −0.00 for pubertal and postpubertal); all P > 0.05. The HOMA-IR showed a good discriminatory power for detecting IR with an area under the receiver operator characteristic curve of 0.870 (95% CI, 0.718-0.957) in pubertal and 0.861 (95% CI, 0.721-0.947) in postpubertal adolescents; all P < 0.001. The optimal cutoff values of the HOMA-IR for detecting IR were > 3.22 (sensitivity, 85.7; 95% CI, 57.2-98.2; specificity, 82.6; 95% CI, 61.2-95.0) for pubertal and > 2.91 (sensitivity, 63.6; 95% CI, 30.8-89.1, specificity, 93.7; 95%CI, 79.2-99.2) for postpubertal adolescents. Conclusion: The threshold value of the HOMA-IR for identifying insulin resistance was > 3.22 for pubertal and > 2.91 for postpubertal adolescents.

Abstract Objective: The aim of our study was to evaluate the expression of MMP-2 and MMP-9 as a prognostic factor in patients diagnosed with Hodgkin Lymphoma (HL). Methods: In the present study, 45 paraffin biopsies from patients up to 19 years old diagnosed with HL were used in two referral hospitals in the state of Pernambuco, Brazil. Risk groups were classified into favorable and unfavorable, according to Ann Arbor. The expression of matrix metalloproteinases 2 and 9 and their inhibitors was performed by immunohistochemistry (IHC). Data were analyzed using the GraphPad Prism 5 program. Results: MMP-2 intensity pattern was stronger (> 10% of the total field) in patients with stage III/ IV and B symptoms. MMP-2 showed an association with the risk group (p = 0.0388). That is, the stronger the MMP-2 marking, the greater the unfavorable risk. However, for MMP-9 there was no difference in the stronger intensity pattern in relation to stages I/II and III/IV, only in the presence of B symptoms. MMP-9 showed an association with B Symptoms (p = 0.0411). Therefore, patients with B symptoms have higher MMP-9 expression. Conclusion: Our results suggest that MMP-2 expression is associated with HL progression. While MMP-9 expression is related to the clinical worsening of these patients. However, further studies are needed to evaluate the exact role of these proteins in hematologic malignancies.

Abstract Background Human Papillomavirus (HPV) is the main etiological factor for the development of cervical cancer. HPV 18 is the second most frequent type, accounting for up to 65% of all cases. HPV intratypic variation may influence the potential for progression to invasive cancer. The aim of this study was to evaluate the prevalence of human papillomavirus 18 intratypic variants in cervical cancer samples from women in the state of Maranhão, Brazil. Methods The study included 118 women over 18 years of age with a diagnosis of cervical cancer. Tumor fragments were collected and subjected to DNA extraction and Polymerase Chain Reaction (PCR) for HPV detection using the PGMY09/11 and GP+5/6 primers. Positive samples were submitted to automated sequencing for viral genotyping. To determine the HPV 18 lineages, positive samples were submitted to PCR, using specific primers to amplify the LCR and E6 regions of HPV 18 virus. Results HPV was present in 88 women (73.3%). Of those, 48 (54%) were HPV 16, the most prevalent, followed by 12 (13.6%) HPV 18. Histologically, squamous cell carcinoma was predominant (79.1%). Among the HPV 18 variants identified, 10 (80%) belonged to lineage A, and sublineages A1, A2, A3, and A4. Two (29%) HPV 18 B variant was also detected, with the sublineages B1 and B2. In this study, the C variant was not found. There was no statistically significant association between the HPV 18 lineages found and sociodemographic and lifestyle variables (p > 0.05). Conclusions A higher frequency of HPV 16 and 18 were found in women with cervical cancer in the state of Maranhão, Brazil, with a high prevalence of the lineage A among women with HPV 18.

Abstract The pathogenesis of systemic lupus erythematosus (SLE) is complex. Few studies in Brazilian population have addressed cell phenotypes associated with immunological responses and their associations with SLE activity. The aim of this study is to investigate cell phenotypes associated to SLE diagnosis, treatment and activity. Twenty-eight SLE female patients (17 inactive, 11 active) and 10 healthy women were included in this study. Markers of natural killer (Nk), T and B cells in peripheral blood were evaluated by flow cytometry. Nkt cells were decreased only in SLE active patients. Activated CD4+, regulatory T FoxP3+ and B cells were decreased in both active and inactive SLE patients, compared to control group. The data corroborate the disruption of immune regulatory response in SLE patients and suggest phenotipic changes as possible biomarkers of SLE activity.

ABSTRACT Children have an increased likelihood of becoming carriers of the chronic hepatitis B virus. A total of 1,381 children and adolescents were assessed in five municipalities of Maranhao State, Brazil, for detection of anti-HBc, HBsAg and anti-HBs serologic markers and sociodemographic and behavioral features. Among those who were HBsAg negative and anti-HBc negative, the proportion of anti-HBs positives was calculated after the individuals had completed the vaccination schedule. The robust variance of the Poisson’s regression model was used in order to have adjusted tables and calculate the prevalence ratio. Multivariate analysis was performed to identify the factors associated with the prevalence of anti-HBc with or without HBsAg and the vaccine response. It was observed that 163 children were anti-HBc positive and nine individuals were HBsAg positive. The factors associated with the infection were: municipality of residence (residing in Morros municipality or Humberto de Campos municipality), residence in a rural area, aged between 13 and 15 years old, and illicit drug use. The percentage of individuals who were anti-HBc negative and received all three doses of the vaccine was 48.5%. Among these, only 276 (38.9%) had antibodies at protective concentrations. In an adjusted analysis, Morros municipality presented an increased positivity of vaccine response (p < 0.001), and the age ranging between 6 and 10 years old presented a reduced frequency of response. This study reveals a high prevalence of current and past HBV infection within the targeted age group which, in addition to the low vaccination coverage and serological responses, raises concerns about the management of prevention measures, especially the quality of vaccination in these locations.

Abstract Background Cardiovascular complications of COVID-19 are important aspects of the disease’s pathogenesis and prognosis. Evidence on the prognostic role of troponin and myocardial injury in Latin American hospitalized COVID-19 patients is still scarce. Objectives To evaluate myocardial injury as independent predictor of in-hospital mortality and invasive mechanical ventilation support in hospitalized patients, from the Brazilian COVID-19 Registry. Methods This cohort study is a substudy of the Brazilian COVID-19 Registry, conducted in 31 Brazilian hospitals of 17 cities, March-September 2020. Primary outcomes included in-hospital mortality and invasive mechanical ventilation support. Models for the primary outcomes were estimated by Poisson regression with robust variance, with statistical significance of p<0.05. Results Of 2,925 patients (median age of 60 years [48-71], 57.1% men), 27.3% presented myocardial injury. The proportion of patients with comorbidities was higher among patients with cardiac injury (median 2 [1-2] vs. 1 [0-2]). Patients with myocardial injury had higher median levels of brain natriuretic peptide, lactate dehydrogenase, creatine phosphokinase, N-terminal pro-brain natriuretic peptide, and C-reactive protein than patients without myocardial injury. As independent predictors, C-reactive protein and platelet counts were related to the risk of death, and neutrophils and platelet counts were related to the risk of invasive mechanical ventilation support. Patients with high troponin levels presented a higher risk of death (RR 2.03, 95% CI 1.60-2.58) and invasive mechanical ventilation support (RR 1.87, 95% CI 1.57-2.23), when compared to those with normal troponin levels. Conclusion Cardiac injury was an independent predictor of in-hospital mortality and the need for invasive mechanical ventilation support in hospitalized COVID-19 patients.

Resumo Fundamento As complicações cardiovasculares da COVID-19 são aspectos importantes da patogênese e do prognóstico da doença. Evidências do papel prognóstico da troponina e da lesão miocárdica em pacientes hospitalizados com COVID-19 na América Latina são ainda escassos. Objetivos Avaliar a lesão miocárdica como preditor independente de mortalidade hospitalar e suporte ventilatório mecânico em pacientes hospitalizados, do registro brasileiro de COVID-19. Métodos Este estudo coorte é um subestudo do registro brasileiro de COVID-19, conduzido em 31 hospitais brasileiros de 17 cidades, de março a setembro de 2020. Os desfechos primários incluíram mortalidade hospitalar e suporte ventilatório mecânico invasivo. Os modelos para os desfechos primários foram estimados por regressão de Poisson com variância robusta, com significância estatística de p<0,05. Resultados Dos 2925 pacientes [idade mediana de 60 anos (48-71), 57,1%], 27,3% apresentaram lesão miocárdica. A proporção de pacientes com comorbidades foi maior nos pacientes com lesão miocárdica [mediana 2 (1-2) vs. 1 (0-20)]. Os pacientes com lesão miocárdica apresentaram maiores valores medianos de peptídeo natriurético cerebral, lactato desidrogenase, creatina fosfoquinase, N-terminal do pró-peptídeo natriurético tipo B e proteína C reativa em comparação a pacientes sem lesão miocárdica. Como fatores independentes, proteína C reativa e contagem de plaquetas foram relacionados com o risco de morte, e neutrófilos e contagem de plaquetas foram relacionados ao risco de suporte ventilatório mecânico invasivo. Os pacientes com níveis elevados de troponina apresentaram um maior risco de morte (RR 2,03, IC95% 1,60-2,58) e suporte ventilatório mecânico (RR 1,87;IC95% 1,57-2,23), em comparação àqueles com níveis de troponina normais. Conclusão Lesão cardíaca foi um preditor independente de mortalidade hospitalar e necessidade de suporte ventilatório mecânico em pacientes hospitalizados com COVID-19.

ABSTRACT Sporotrichosis is the most frequent subcutaneous mycosis in Latin America. It is caused by species of the genus Sporothrix. Infection in humans occurs through the entry of the fungus into the skin. Zoonotic outbreaks involving cats in the transmission of the disease have been frequently reported. The lymphocutaneous form is the most commonly observed and the upper limbs are the most affected sites. We report a case of a 64-year-old healthy female patient with a lymphocutaneous form with rapid progression of lesions, which was refractory to initial treatment with itraconazole. Treatment with liposomal amphotericin B was performed with a satisfactory resolution, but aesthetic and functional sequelae in the left upper limb were installed.
