ABSTRACT: Protocols to artificially induce cows and heifers into lactation are effective and commercially available in Brazil. However, these protocols demand long hormonal treatments, which is debatable since little research has been done in the subject. To further understand artificial induction to lactation (AIL) protocols, we conducted two experiments. In experiment 1, our objective was to better characterize steroidal profile during an AIL protocol and assess the estradiol (E2) and progesterone (P4) serum profiles of Jersey cows (n=6) subjected to a conventional protocol. In experiment 2, we aimed to compare milk production and serum E2 concentrations of Holstein heifers induced into lactation by the standard AIL protocol (15 injections of E2 and 8 P4 injections) and by a short protocol in which the number of E2 injections and, consequently, the overall dosage of E2, were reduced (8 injections of E2 and 8 P4 injections). We hypothesized that a short AIL protocol (8 days) would be as efficient as the long standard protocol of 15 days. Our hypothesis was confirmed, since we demonstrated that a shorter protocol was able to induce lactation in Holstein heifers without hindering milk production.

RESUMO: Protocolos que induzem à lactação artificial em vacas e novilhas são eficazes e estão comercialmente disponíveis no Brasil. No entanto, esses protocolos demandam longos tratamentos hormonais, o que é discutível visto que poucas pesquisas foram feitas sobre o assunto. Para entender melhor os protocolos de indução artificial à lactação (IAL), realizamos dois experimentos. Foi testada a hipótese de que um protocolo curto (oito dias) de IAL é tão eficiente quanto o protocolo padrão de 15 dias. No experimento 1 objetivou-se caracterizar o perfil esteroidal durante um protocolo de IAL e avaliou-se os perfis séricos de estradiol (E2) e progesterona (P4) de vacas Jersey (n=6) submetidas a um protocolo convencional. No experimento 2 foram comparadas a produção de leite e as concentrações séricas de E2 de novilhas holandesas induzidas à lactação pelo protocolo padrão de IAL (15 injeções de E2 e 8 injeções de P4) e por um protocolo curto, no qual o número de injeções de E2 e, consequentemente, a dosagem geral de E2 foram reduzidas (oito injeções de E2 e oito injeções de P4). A hipótese foi confirmada, demonstrado que um protocolo mais curto induziu a lactação em novilhas holandesas sem prejudicar a produção de leite.

Abstract Inflammatory bowel disease (IBD) is a problem that directly affects the quality of life of patients suffering from this condition. Monitoring the serum level of infliximab (IFX) (TDM) is an important tool for guiding therapeutic decisions in IBD patients. The purpose of this study was to determine the significance of quantitatively measuring the serum level of IFX (TDM) and antibody to IFX (ATI). Methods and materials: Prospective observational study involving 40 IBD patients on IFX therapy, including 14 Proactive (week 06 of the induction phase) and 26 Reactive (maintenance phase). Immediately prior to the infusion, blood samples were drawn and measured using a Bulhlmann rapid test instrument. Serum concentrations of IFX were categorized as supratherapeutic (>7.0 micrograms/ml), therapeutic (between 3.0 and 7.0 micrograms/ml), and subtherapeutic (3.0 micrograms/ml). When the serum concentration of IFX was 3 mcg/ml (subtherapeutic), the ATI was measured. 25 patients with CD and 15 patients with UC were evaluated. Only three of the twenty patients with subtherapeutic serum levels had a positive ATI, and both were reactive; two had CD and one had UC. There was a statistically significant difference between reactive and proactive patients with respect to levels of CRP (p = 0.042), with proactive DNS patients suffering greater alterations in CRP and albumin.

ABSTRACT Afforestation of sites disturbed after bauxite mining is the favorite technique to restore all ecosystem functions. The nature of the tree species used for revegetation of post-mining land can accelerate the recovery of soil organic matter and nutrient cycles. This study aimed to determine the litterfall production, decomposition rate and nutrient content from three types of forest cover ( Eucalyptus , Anadenanthera peregrina , mixed plantation of 16 native species) planted in a bauxite mining area in recovery. Litterfall production was evaluated monthly over 30 months, and the litter mass was assessed twice a year (dry and rainy periods). Total nutrient content was determined from samples grouped by period (dry and rainy). The annual average values for litterfall dry mass and litter mass were higher in Eucalyptus and mixed native. The period (dry or rainy) did not influence litterfall rates in A. peregrina , but Eucalyptus and mixed native presented higher amounts for litterfall during the rainy and dry periods, respectively. Litter accumulation in Eucalyptus was not affected by the season of the year, but mixed native and A. peregrina presented higher litter accumulation in the dry season. Apparent decomposition rates of A. peregrina and mixed native were higher in the rainy season, highlighting the A. peregrina with the highest values compared with the other forest covers. The mixed native presented the highest leaf content of P, K, Ca and Mg in both the litterfall and litter mass, while Eucalyptus had the lowest P, K, Ca, S and N content and the highest C content in the litterfall. Litterfall production is important in degraded areas to ensure the nutrient return to the soil. The data obtained suggest that the cultivation of a mixed of 16 native trees contribute for produce the higher annual litterfall yields, besides produces leaf litterfall of better nutritional quality in relation to P, K, Ca, Mg and S. Therefore, mixed of native trees can be a promising option for reactivation of nutrient cycling and organic matter formation in mined area of bauxite in the Brazilian Atlantic Forest.

ABSTRACT Background: Cases of coronavirus disease 2019 (COVID-19) requiring hospitalization continue to appear in vulnerable populations, highlighting the importance of novel treatments. The hyperinflammatory response underlies the severity of the disease, and targeting this pathway may be useful. Herein, we tested whether immunomodulation focusing on interleukin (IL)-6, IL-17, and IL-2, could improve the clinical outcomes of patients admitted with COVID-19. Methods: This multicenter, open-label, prospective, randomized controlled trial was conducted in Brazil. Sixty hospitalized patients with moderate-to-critical COVID-19 received in addition to standard of care (SOC): IL-17 inhibitor (ixekizumab 80 mg SC/week) 1 dose every 4 weeks; low-dose IL-2 (1.5 million IU per day) for 7 days or until discharge; or indirect IL-6 inhibitor (colchicine) orally (0.5 mg) every 8 hours for 3 days, followed by 4 weeks at 0.5 mg 2x/day; or SOC alone. The primary outcome was accessed in the “per protocol” population as the proportion of patients with clinical improvement, defined as a decrease greater or equal to two points on the World Health Organization’s (WHO) seven-category ordinal scale by day 28. Results: All treatments were safe, and the efficacy outcomes did not differ significantly from those of SOC. Interestingly, in the colchicine group, all participants had an improvement of greater or equal to two points on the WHO seven-category ordinal scale and no deaths or patient deterioration were observed. Conclusions: Ixekizumab, colchicine, and IL-2 were demonstrated to be safe but ineffective for COVID-19 treatment. These results must be interpreted cautiously because of the limited sample size.

Abstract Objective To verify the influence of low birth weight and rapid postnatal weight gain and associated factors on blood pressure in adolescence in a population of low socioeconomic status, considering that injuries occur in the perinatal period can be predictors of future metabolic changes and are still poorly explored. Methods A cohort study was carried out with 208 adolescents, 78 born with low weight and 130 born with appropriate weight. The infants were followed up during the first six postnatal months and reassessed at 8 and 18 years of age. The independent variables were birthweight and postnatal weight gain. Rapid postnatal weight gain was defined when above 0.67 z score. The co-variables were sex, maternal height and family income at birth, nutritional status at eight years old, socioeconomic conditions, nutritional status, fat mass index, and physical activity level at 18 years. The outcome variable was blood pressure at 18 years old. The bivariate and multivariable logistic regression analysis were realized and p < 0,05 was considered significant. Results The proportion of adolescents with elevated blood pressure was 37.5%. The multivariable logistic regression analysis showed the variables independently associated with a higher chance of elevated blood pressure in adolescence were rapid postnatal weight gain (OR = 2.74; 95% CI 1.22-6.14; p= 0.014), male sex (OR = 4.15; 95% CI 1.66-10.38; p= 0.002) and being physically active (OR = 2.70; 95% CI 1.08-6.74; p= 0.034). Conclusions The rapid postnatal weight gain was a predictor for elevated blood pressure in adolescence, independently of other factors.

Abstract Objective To evaluate clinical characteristics and outcomes of COVID-19 patients infected with HIV, and to compare with a paired sample without HIV infection. Methods This is a substudy of a Brazilian multicentric cohort that comprised two periods (2020 and 2021). Data was obtained through the retrospective review of medical records. Primary outcomes were admission to the intensive care unit, invasive mechanical ventilation, and death. Patients with HIV and controls were matched for age, sex, number of comorbidities, and hospital of origin using the technique of propensity score matching (up to 4:1). They were compared using the Chi-Square or Fisher's Exact tests for categorical variables and the Wilcoxon for numerical variables. Results Throughout the study, 17,101 COVID-19 patients were hospitalized, and 130 (0.76%) of those were infected with HIV. The median age was 54 (IQR: 43.0;64.0) years in 2020 and 53 (IQR: 46.0;63.5) years in 2021, with a predominance of females in both periods. People Living with HIV (PLHIV) and their controls showed similar prevalence for admission to the ICU and invasive mechanical ventilation requirement in the two periods, with no significant differences. In 2020, in-hospital mortality was higher in the PLHIV compared to the controls (27.9% vs. 17.7%; p = 0.049), but there was no difference in mortality between groups in 2021 (25.0% vs. 25.1%; p > 0.999). Conclusions Our results reiterate that PLHIV were at higher risk of COVID-19 mortality in the early stages of the pandemic, however, this finding did not sustain in 2021, when the mortality rate is similar to the control group.

ABSTRACT Coronary artery fistula draining into the coronary sinus is a rare vascular malformation, and its diagnosis and clinical manifestations usually occur late. We describe the case of a 72-year-old female patient with dyspnea on exertion (New York Heart Association Class III) associated with palpitations. The transthoracic echocardiogram showed significant tricuspid insufficiency. Cardiac catheterization showed aneurysm of the circumflex coronary artery and fistula of this artery draining into the coronary sinus. The patient underwent fistula ligation and tricuspid valve repair, with excellent surgical results.

Abstract Background: The use of combined oral contraceptives (COC) is a risk factor for atherosclerotic disease, and physical exercise can minimize this condition. Objective: To verify if high intensity interval training (HIIT) promotes changes in the lipid and inflammatory profile of women using COC. Methods: Sequential crossover study with women aged 20-30 years, classified as irregularly active by the international physical activity questionnaire (IPAQ), when using COC. A physical-clinical assessment was performed with anthropometric measurements, VO2max, and analysis of lipid and inflammatory profile. Participants were divided into 2 groups: the initial intervention group (GII), which began practicing HIIT for 2 months, and the posterior intervention group (GIP), which remained inactive for the same period. The GII and GIP would then alternate their conditions. The collected data was divided into: Initial moment (IM), post-exercise moment (PEM) and post-inactivity (PIM). The statistical analyses were performed using the Statistical Package for the Social Sciences, adopting a significance level of p <0.05 . Results: Twelve women were evaluated. After crossing the GII and GIP data, there was a difference in the C-reactive protein values between the IM of 4 (1.6-6.3 mg/dL) vs. PEM 2 (1.5-5 mg/dL); as well as between the PEM vs. the PIM= 4 (1.5-5.8 mg/dL), with a p -value = 0.04 in the comparisons. There was no change between the “moments” of the lipid profile, although it was possible to notice a reduction in resting HR and an increase in indirect VO2max. Conclusion: The HIIT program was able to reduce the inflammatory profile, but it did not alter the lipid profile of irregularly active women using COC.

RESUMO Objetivos: Há diversas terapias sendo utilizadas ou propostas para a COVID-19, muitas carecendo de apropriada avaliação de efetividade e segurança. O propósito deste documento é elaborar recomendações para subsidiar decisões sobre o tratamento farmacológico de pacientes hospitalizados com COVID-19 no Brasil. Métodos: Um grupo de 27 membros, formado por especialistas, representantes do Ministério da Saúde e metodologistas, integra essa diretriz. Foi utilizado o método de elaboração de diretrizes rápidas, tomando por base a adoção e/ou a adaptação de recomendações a partir de diretrizes internacionais existentes (GRADE ADOLOPMENT), apoiadas pela plataforma e-COVID-19 RecMap. A qualidade das evidências e a elaboração das recomendações seguiram o método GRADE. Resultados: Foram geradas 16 recomendações. Entre elas, estão recomendações fortes para o uso de corticosteroides em pacientes em uso de oxigênio suplementar, para o uso de anticoagulantes em doses de profilaxia para tromboembolismo e para não uso de antibacterianos nos pacientes sem suspeita de infecção bacteriana. Não foi possível fazer uma recomendação quanto à utilização do tocilizumabe em pacientes hospitalizados com COVID-19 em uso de oxigênio, pelas incertezas na disponibilidade e de acesso ao medicamento. Foi feita recomendação para não usar azitromicina, casirivimabe + imdevimabe, cloroquina, colchicina, hidroxicloroquina, ivermectina, lopinavir/ ritonavir, plasma convalescente e rendesivir. Conclusão: Até o momento, poucas terapias se provaram efetivas no tratamento do paciente hospitalizado com COVID-19, sendo recomendados apenas corticosteroides e profilaxia para tromboembolismo. Diversos medicamentos foram considerados ineficazes, devendo ser descartados, de forma a oferecer o melhor tratamento pelos princípios da medicina baseada em evidências e promover economia de recursos não eficazes.

ABSTRACT Objective: Several therapies are being used or proposed for COVID-19, and many lack appropriate evaluations of their effectiveness and safety. The purpose of this document is to develop recommendations to support decisions regarding the pharmacological treatment of patients hospitalized with COVID-19 in Brazil. Methods: A group of 27 experts, including representatives of the Ministry of Health and methodologists, created this guideline. The method used for the rapid development of guidelines was based on the adoption and/or adaptation of existing international guidelines (GRADE ADOLOPMENT) and supported by the e-COVID-19 RecMap platform. The quality of the evidence and the preparation of the recommendations followed the GRADE method. Results: Sixteen recommendations were generated. They include strong recommendations for the use of corticosteroids in patients using supplemental oxygen, the use of anticoagulants at prophylactic doses to prevent thromboembolism and the nonuse of antibiotics in patients without suspected bacterial infection. It was not possible to make a recommendation regarding the use of tocilizumab in patients hospitalized with COVID-19 using oxygen due to uncertainties regarding the availability of and access to the drug. Strong recommendations against the use of hydroxychloroquine, convalescent plasma, colchicine, lopinavir + ritonavir and antibiotics in patients without suspected bacterial infection and also conditional recommendations against the use of casirivimab + imdevimab, ivermectin and rendesivir were made. Conclusion: To date, few therapies have proven effective in the treatment of hospitalized patients with COVID-19, and only corticosteroids and prophylaxis for thromboembolism are recommended. Several drugs were considered ineffective and should not be used to provide the best treatment according to the principles of evidence-based medicine and promote economical resource use.

Abstract INTRODUCTION: Cancers are the second main cause of morbidity worldwide, but robust information on lip, oral cavity, and pharynx cancers in Brazil is lacking. This study aimed to analyze the trends of incidence and mortality caused by lip, oral cavity, and pharynx cancers and age-period-cohort effects in the Brazilian population of 30 years of age and over, in the period of 1990 to 2019. METHODS: A time series study of the incidence and mortality rates for oral cavity and pharynx cancer (“Lip and oral cavity cancer”, “Nasopharynx cancer”, and “Other pharynx cancer”) was conducted, with corrected data from the Global Burden of Disease Study (GBD) 2019. Age-standardized rates per 100,000 inhabitants, for the global population, were gathered according to the individuals’ sex. The annual average percentage change (AAPC) was estimated, as was the age-period-cohort effects. RESULTS: The incidence and mortality rates were higher for men in the studied anatomical regions. The cancers tended to decrease for men, except for nasopharynx cancer, which increased in individuals of both sexes. Mortality tended to present a decline in most of the groups studied. For men and women, the age-period-cohort model presented a better adjustment for both incidence and mortality. CONCLUSIONS: Incidence and mortality caused by the main head and neck cancers showed a tendency to decline over the past 30 years in Brazil, except for nasopharynx cancer, which showed an increase in incidence and mortality in some segments of the population. Higher rates were found for lip and oral cavity cancers in men.

ABSTRACT BACKGROUND: We aimed to describe the clinical characteristics of coronavirus disease 2019 (COVID-19) among healthcare workers (HCWs) in Curitiba, Brazil. METHODS: Upper respiratory samples from 1077 HCWs were tested for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using reverse transcription polymerase chain reaction from June 16, 2020 to December 9, 2020. RESULTS: Overall, 32.7% of HCWs were infected. The positivity rates in symptomatic and asymptomatic HCWs were 39.2% and 15.9%, respectively. Hospital departments categorized as high-risk for exposure had the highest number of infected HCWs. CONCLUSIONS: Early diagnosis and isolation of infected HCWs remain key in controlling SARS-CoV-2 transmission because HCWs in close contact with COVID-19 patients are more likely to be infected than those who are not.

O uso da teleoftalmologia pode ser uma estratégia viável para rastrear e diagnosticar as principais doenças oculares em pacientes na atenção primária à saúde. O objetivo deste estudo é descrever a realização de 30.315 telediagnósticos em oftalmologia em pacientes da atenção primária e a resolutividade desse serviço. Estudo transversal para avaliar os telediagnósticos realizados em pacientes atendidos nos oito pontos remotos do projeto TeleOftalmo entre 2 de janeiro de 2018 a 31 de dezembro de 2020. Foram avaliadas as características demográficas dos pacientes, os motivos de encaminhamento, os diagnósticos realizados conforme faixa etária e a resolutividade do telediagnóstico. Os pacientes eram, na maioria, do sexo feminino (66,1%), adultos (70,3%) e encaminhados ao telediagnóstico principalmente devido à baixa acuidade visual (60,5%). Os erros refrativos foram o diagnóstico mais prevalente em todas as faixas etárias. A presbiopia foi a doença ocular mais prevalente em adultos (65,4%) e idosos (64%), seguida da catarata (41,3%) e suspeita de glaucoma (10,6%) em idosos. Dos 30.315 pacientes que realizaram o telediagnóstico, 70,5% tiveram suas queixas oculares totalmente solucionadas, sem a necessidade de encaminhamento ao oftalmologista presencial. A telemedicina pode ser resolutiva para as doenças oculares mais prevalentes na população, aumentando a oferta de diagnósticos, qualificando e auxiliando na redução das filas de espera por atendimento oftalmológico.

The use of teleophthalmology may be a viable strategy to track and to diagnose major eye diseases primary health care patients. This study aimed to describe the performance of 30,315 telediagnoses in ophthalmology in primary care patients and the case management of this service. This is a cross-sectional study to evaluate the telediagnosis performed in patients treated at the eight remote points of the TeleOftalmo project from January 2nd, 2018, to December 31st, 2020. The patients’ demographic characteristics, the reasons for referral, the diagnoses made according to age group, and the case management of the telediagnosis were evaluated. Most patients were female (66.1%), adults (70.3%), and referred to telediagnosis mainly due to reduced visual acuity (60.5%). Refractive errors were the most prevalent diagnosis in all age groups. Presbyopia was the most prevalent eye disease in adults (65.4%) and older adults (64%), followed by cataracts (41.3%) and suspected glaucoma (10.6%) in older adults. In total, 30,315 patients underwent telediagnosis, 70.5% had their ocular complaints fully resolved, without the need for referral to an in-person ophthalmologist. Telemedicine can be resolutory for the most prevalent eye diseases in the population, increasing the supply of diagnoses, qualifying and assisting in reducing waiting lines for ophthalmologic care.

La teleoftalmología puede ser una estrategia viable para el tamizaje y diagnóstico de las principales enfermedades oculares en pacientes en la atención primaria de salud. El objetivo de este estudio es describir la realización de 30.315 telediagnósticos en oftalmología en pacientes de atención primaria y la resolución de este servicio. Estudio transversal para evaluar los telediagnósticos realizados a pacientes en los ocho puntos de atención remota del proyecto TeleOftalmo entre el 2 de enero de 2018 y el 31 de diciembre de 2020. Se evaluaron las características demográficas de los pacientes, los motivos de derivación, los diagnósticos realizados según el grupo de edad y la resolución de los telediagnósticos. Los pacientes eran en su mayoría mujeres (66,1%), adultos (70,3%) y remitidos para telediagnóstico, principalmente por baja agudeza visual (60,5%). Los errores de refracción fueron el diagnóstico más prevalente en todos los grupos de edad. La presbicia fue la enfermedad ocular más frecuente en adultos (65,4%) y ancianos (64%), seguida de catarata (41,3%) y sospecha de glaucoma (10,6%) en ancianos. De los 30.315 pacientes que realizaron el telediagnóstico, el 70,5% tuvo sus quejas oculares totalmente resueltas, sin necesidad de derivación presencial al oftalmólogo. La telemedicina puede ser una herramienta útil para detectar las enfermedades oculares más prevalentes en la población debido al aumento de los diagnósticos y la ayuda que produce al reducir la lista de espera para atención oftalmológica.

Resumo Introdução: Alterações causadas no metabolismo de quem pratica exercício físico constantemente geram benefícios à saúde. Em atletas, porém, causam danos musculares e por isso métodos de recuperação pós-esforço são de extrema importância para a manutenção fisiológica de atletas. Objetivo: Analisar a eficácia da técnica de contraste com recuperação pós-esforço segundo atletas profissionais. Métodos: Aplicou-se um questionário online que abordou o conhecimento técnico científico de atletas profissionais acima de 18 anos, de ambos os sexos, sobre técnicas de recuperação pós-esforço (TRPE), informações pessoais e questões éticas. Realizou-se análise estatística descritiva, onde os valores foram apresentados em percentuais, e associação através do teste qui-quadrado sobre o conhecimento das TRPE e demais variáveis independentes. Resultados: Responderam ao questionário online 63 atletas, 15 mulheres e 48 homens, sendo que 71,4% tinham entre 18 e 30 anos de idade. Estes eram nadadores, futebolistas e praticantes de atletismo; 85,7% possuíam experiência superior a três anos na modalidade e 57,1% competiam em nível internacional. Sobre as principais TRPE, 92,1% tinham conhecimento, 58,7% conheciam mais de quatro, 96,8% usavam com frequência ao menos uma TRPE e 65,1% utilizavam a mais de três anos. O conhecimento de TRPE está associado à idade (p = 0,001), escolaridade (p = 0,001), tempo de prática (p = 0,001), horas de treino diário (0,001) e nível competitivo (p = 0,03). Quanto ao uso da técnica de contraste, 36,5% dos respondentes já a haviam utilizado e, destes, 34,9% a consideram efetiva. Conclusão: Os atletas que utilizaram a técnica de contraste relataram boa percepção de recuperação.

Abstract Introduction: Alterations caused in the metabolism of those who practice physical exercise regularly generate health benefits, however, in athletes, these alterations can cause muscle damage, so post-recovery recovery methods are extremely important for their physiological maintenance. Objective: To analyze the effectiveness of the contrast therapy technique with post-exercise recovery according to professional athletes. Methods: A questionnaire was applied that addressed the technical scientific knowledge of professional athletes over 18 years of age, of both sexes, about post-exerciseffort recovery techniques (PERT), personal information, and ethical issues, on an online platform. Descriptive statistical analysis was performed, with values presented in percentages and an association through the Chi-Square test on the knowledge of PERT and other independent variables. Results: In total, 63 athletes, 15 women and 48 men, answered the online questionnaire, 71.4% were between 18 and 30 years old, including swimmers, footballers, and athletics practitioners, and 85.7% had more than three years' experience in the sport and 57.1% competed at an international level. Considering the main PERTs, 92.1% were aware, 58.7% knew more than four, 96.8% frequently used at least one PERT, and 65.1% had used it for more than three years. Knowledge of PERTs is associated with age (p = 0.001), education (p = 0.001), practice time (p = 0.001), hours of daily training (0.001), and competitive level (p = 0.03). With respect to the use of the contrast technique, 36.5% of the respondents had already used it, and 34.9% found it effective. Conclusion: The athletes who used the contrast technique reported a good perception of recovery.
