Alterações em enzimas musculares de cavalos em competições de enduro de longa distância em clima tropical

Estudaram-se as alterações de atividade das enzimas musculares creatino quinase (CK), lactato desidrogenase (LDH) e aspartato aminotransferase (AST) em um grupo de cavalos que utilizados em provas de enduro de 70 e 100km de distância, em cinco competições. Os valores (U/l) basais (antes da largada) foram 245,13±9,84 para CK, 496,61±14,76 para LDH e 328,95±8,65 para AST. Todas as atividades das enzimas decresceram no primeiro momento das provas (~30km). Valores de pico, significativamente diferentes, foram alcançados para CK (413,59±50,75) imediatamente após 70km de distância; 24 horas após para LDH (628,61±33,30); e 48 horas após as provas para AST (389,89±16,96). A monitoração do período de recuperação revelou diferente comportamento entre as concentrações enzimáticas com CK retornando aos valores basais 24 horas pós-provas (279,61 ± 23,05). LDH e AST retornaram aos valores basais, 72 horas pós-provas (505,25±33,78 e 359,35±24,90, respectivamente). Os dados obtidos revelaram diferentes alterações na concentração de enzimas musculares de cavalos de enduro, diretamente relacionadas com a duração do esforço. _________________________________________________________________________________________________________ ABSTRACTThis study tried to monitor the alterations of muscle enzymes activity - creatinokinase (CK), lactate dehydrogenase (LDH), and aspartate aminotransferase (AST) - in a group of horses that participated of 70 and 100km distance rides in five competitions of an annual endurance championship under tropical climate. Pre ride levels (U/l) were 245.13±9.84 for CK, 496.61±14.76 for LDH, and 328.95±8.65 for AST. When compared to these levels, the results revealed a significant decrease in all enzymes activities in the first moment of the rides. Peak levels, significantly different, were reached, immediately after rides by CK (413.591±50.75); 24 hours post rides by LDH (628.61±33.30); and 48 hours after rides by AST (389.89±16.96). Monitoring of recovery period revealed different behavior among enzymes activities with CK values returning to pre ride values (279.61±23.05) 24 hours post rides, while LDH and AST values returned to pre ride values (505.25±33.78 and 359.35±24.90, respectively) 72 hours post rides. These data revealed different alterations in concentration of muscular enzymes in endurance horses directly related to the duration of the effort

O objetivo do presente artigo é apresentar uma revisão bibliográfica sobre a utilização dos instrumentos de governança pública na gestão dos Regimes Próprios de Previdência Social (RPPS). A pesquisa foi realizada em livros, manuais e artigos científicos publicados em periódicos relevantes. O estudo descreveu os modelos de gestão pública que são praticados no Brasil, demonstrando a influência da cultura patrimonialista e a governança pública como resultado da evolução do gerencialismo. A pesquisa constatou que a governança pública vem sendo aplicada no âmbito da administração pública e que a previdência social vem adotando seus instrumentos, inclusive nos regimes próprios, como é o caso do programa Pró-Gestão RPPS que visa a melhoria da qualidade e capacitação dos gestores públicos

LOCUS (LOng Covid-Understanding Symptoms, events and use of services in Portugal): A three-component study protocol

Study ProtocolApproximately 10% of patients experience symptoms of Post COVID-19 Condition (PCC) after a SARS-CoV-2 infection. Akin acute COVID-19, PCC may impact a multitude of organs and systems, such as the cardiovascular, respiratory, musculoskeletal, and neurological systems. The frequency and associated risk factors of PCC are still unclear among both community and hospital settings in individuals with a history of COVID-19. The LOCUS study was designed to clarify the PCC’s burden and associated risk factors. LOCUS is a multi-component study that encompasses three complementary building blocks. The “Cardiovascular and respiratory events following COVID-19” component is set to estimate the incidence of cardiovascular and respiratory events after COVID-19 in eight Portuguese hospitals via electronic health records consultation. The “Physical and mental symptoms following COVID-19” component aims to address the community prevalence of self-reported PCC symptoms through a questionnaire-based approach. Finally, the "Treating and living with Post COVID-19 Condition" component will employ semi-structured interviews and focus groups to characterise reported experiences of using or working in healthcare and community services for the treatment of PCC symptoms. This multi-component study represents an innovative approach to exploring the health consequences of PCC. Its results are expected to provide a key contribution to the optimisation of healthcare services design.This study is sponsored by Pfizer (grant code #68639655).info:eu-repo/semantics/publishedVersio

Patient-physician discordance in assessment of adherence to inhaled controller medication: a cross-sectional analysis of two cohorts

We aimed to compare patient's and physician's ratings of inhaled medication adherence and to identify predictors of patient-physician discordance.(SFRH/BPD/115169/2016) funded by Fundação para a Ciência e Tecnologia (FCT); ERDF (European Regional Development Fund) through the operations: POCI-01-0145-FEDER-029130 ('mINSPIRERS—mHealth to measure and improve adherence to medication in chronic obstructive respiratory diseases—generalisation and evaluation of gamification, peer support and advanced image processing technologies') cofunded by the COMPETE2020 (Programa Operacional Competitividade e Internacionalização), Portugal 2020 and by Portuguese Funds through FCT (Fundação para a Ciência e a Tecnologia).info:eu-repo/semantics/publishedVersio

Plasma Extracellular Vesicle-Derived TIMP-1 mRNA as a Prognostic Biomarker in Clear Cell Renal Cell Carcinoma:A Pilot Study

The tumor microenvironment has gained a lot of attention from the scientific community since it has a proven impact in the development of tumor progression and metastasis. Extracellular vesicles (EVs) are now considered one of the key players of tumor microenvironment modulation. Clear cell renal cell carcinoma (ccRCC) is the most lethal urological neoplasia and presents a high metastatic potential, which reinforces the need for the development of more effective predictive biomarkers. Our goal was to evaluate the applicability of EV-derived matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) as prognostic biomarkers for ccRCC. To do so, we studied the plasma EV content of 32 patients with localized ccRCC and 29 patients with metastatic ccRCC. We observed that patients with localized disease and tumors larger than 7 cm presented higher levels of plasma EV-derived TIMP-1 mRNA when compared with patients presenting smaller tumors (p = 0.020). Moreover, patients with metastatic disease presented higher levels of EV-derived TIMP-1 mRNA when compared with patients with localized disease (p = 0.002) and when we stratified those patients in high and low levels of TIMP-1 EV-derived mRNA, the ones presenting higher levels had a lower overall survival (p = 0.030). EV-derived TIMP-1 mRNA may be a good prognostic biomarker candidate for ccRCC

Portuguese Football Federation consensus statement 2020: nutrition and performance in football

Nutrition is an undeniable part of promoting health and performance among football (soccer) players. Nevertheless, nutritional strategies adopted in elite football can vary significantly depending on culture, habit and practical constraints and might not always be supported by scientific evidence. Therefore, a group of 28 Portuguese experts on sports nutrition, sports science and sports medicine sought to discuss current practices in the elite football landscape and review the existing evidence on nutritional strategies to be applied when supporting football players. Starting from understanding football's physical and physiological demands, five different moments were identified: preparing to play, match-day, recovery after matches, between matches and during injury or rehabilitation periods. When applicable, specificities of nutritional support to young athletes and female players were also addressed. The result is a set of practical recommendations that gathered consensus among involved experts, highlighting carbohydrates periodisation, hydration and conscious use of dietary supplements.info:eu-repo/semantics/publishedVersio

Estudo Vida e Saúde em Pomerode (SHIP-Brazil): objetivos, aspectos metodológicos e resultados descritivos

Background Few studies compared populations with similar genetic and culture background on different continents with standardized methods. Objective To describe methodological issues of the Study of Health in Pomerode - SHIP-Brazil and some characteristics of the participants of the baseline examination. Design and Setting Prospective, population-based cohort study of a representative sample of residents (aged 20 to 79 years) of Pomerode, Santa Catarina, Brazil. Methods Data for the baseline survey (from 2014 to 2018) were collected through interviews and medical examinations, including socio-demographic and lifestyle information, clinical and subclinical conditions, oral and mental health, among others. Biosamples (blood, urine, stool, and saliva) were collected and stored. Methods of data collection and quality control are described. Preliminary descriptive statistics were performed. Results The response rate was 67.6% (n=2,488 individuals). The Kappa test-retest of some variables varied from 0.54 to 1.0. German culture participants are older (46.5 vs 38.7 years), self-declared white (97.3% vs 82.1%), more frequently never smokers (71.4% vs 66.9%) but had higher risk of consuming alcohol (16.9% vs 13.4%) compared to participants with non-German background. Germans were taller (169 cm vs 166 cm), had greater abdominal circumference among men (101.9 cm vs 97.3 cm). Furthermore, they reported more multimorbidity (56.7% vs 43.6%) , had more arterial hypertension (30.7% vs 18.5%), but less depression (15.4% vs 19,1%) than non-Germans. Conclusions The interaction of genetic and social/environmental issues should be examined to understand the role of risk factors on clinical conditions observed.Introdução Poucos estudos compararam populações com histórico genético e cultural semelhante em diferentes continentes com métodos padronizados. Objetivos Descrever questões metodológicas do estudo de “Vida e Saúde em Pomerode - SHIP-Brazil” e algumas características dos participantes do exame inicial do estudo. Desenho de estudo e local Estudo de coorte prospectivo de base populacional em amostra representativa de moradores (20 a 79 anos) de Pomerode, Santa Catarina. Métodos As informações para a linha de base (de 2014 a 2018) foram coletadas por meio de entrevistas e exames médicos, incluindo dados sociodemográficos, de estilo de vida, condições clínicas e subclínicas, saúde bucal e mental, entre outros. Amostras biológicas (sangue, urina, fezes e saliva) foram coletadas e armazenadas. A coleta de dados e o controle de qualidade foram descritos. Foram realizadas análises descritivas preliminares. Resultados A taxa de resposta foi de 67,6% (n=2.488 indivíduos). O Kappa teste-reteste de algumas variáveis variou  de 0,54 a 1,0. Os participantes de cultura alemã são mais velhos (46,5 vs 38,7 anos ), autodeclarados brancos (97,3% vs 82,1%), com menor número de fumantes (71,4% vs 66,9%), mas tiveram maior risco de consumir álcool (16,9% vs 13,4%), eram mais altos (169 cm vs 166 cm), tinham maior circunferência abdominal entre os homens (101,9 cm vs 97,3 cm) em comparação com participantes “não-alemães”. Pessoas de cultura alemã relataram mais multimorbidade (56,7% vs 43,6%), apresentavam mais hipertensão arterial (30,7% vs 18,5%), mas menos depressão (15,4% vs 19,1%). Conclusões A interação genética e social/ambiental devem ser examinadas para melhor entender o papel desses fatores de risco nas condições clínicas observadas
