Abstract Objective To calculate the minimal important clinical difference (MICD) value for the Lysholm and International Knee Documentation Committee (IKDC) scores in a sample of patients submitted to anterior cruciate ligament reconstruction. Methods Primary, observational, retrospective, analytical study of participants submitted to anterior cruciate ligament reconstruction from March 2019 to December 2020 by the same surgeon, with a minimum follow-up of 6 months, analysis of knee function in the pre- and postoperative period by the Lysholm and IKDC scores, and answer to an anchor question at 6 months postoperatively for the calculation of the MICD of each score. Results A total of 59 patients participated in the study, with a mean age of 27.1 ± 5.7 years old. In the comparison between pre- and postoperative scores of all groups, there was an increase in values with statistical significance after intervention. The MICD was 5.5 for the Lysholm score, and the MICD value for the IKDC score could not be determined. Conclusion For the Lysholm score, the calculation of the MICD value by the anchor question method in the sample evaluated was 5.5. It was not possible to determine the value of the MICD for the IKDC score.

Avaliação do Impacto da Implantação de um Sistema de Ambulância Pré-Hospitalar sobre Mortalidade por Infarto Agudo do Miocárdio em um País em Desenvolvimento / Assessment of the Impact of the Implementation of a Pre-Hospital Ambulance System on Acute Myocardial Infarction Mortality in a Developing Country

Resumo Fundamento O manejo efetivo de pacientes com infarto agudo do miocárdio (IAM) é tempo-dependente. Objetivos Avaliar os impactos da implantação do atendimento pré-hospitalar nas taxas de internação e de mortalidade associadas ao IAM. Métodos Estudo retrospectivo e ecológico, que avaliou dados do Sistema Único de Saúde, de todos os 853 municípios de Minas Gerais, de 2008 a 2016. A assimetria excessiva da mortalidade geral e intra-hospitalar por IAM foi suavizada usando o método empírico de Bayes. Este estudo avaliou a relação entre o do Serviço de Atendimento Médico de Urgência (SAMU) em cada município e os seguintes 3 desfechos: taxa de mortalidade geral por IAM, taxa de mortalidade intra-hospitalar por IAM e taxa de internação por IAM, utilizando o modelo hierárquico de Poisson. As taxas foram corrigidas pela estrutura etária e destendenciadas pela sazonalidade e influências temporais. Foi adotado um intervalo de confiança de 95%. Resultados As taxas de mortalidade por IAM diminuíram ao longo do estudo, em média 2% por ano, com variação sazonal. A mortalidade intra-hospitalar também apresentou tendência de queda, de 13,81% em 2008 para 11,43% em 2016. A implantação do SAMU foi associada à diminuição da mortalidade por IAM ( odds ratio [OR] = 0,967, IC 95% 0,936 a 0,998) e mortalidade intra-hospitalar por IAM (OR = 0,914, IC 95% 0,845 a 0,986), sem associação significativa com internações (OR 1,003, IC 95% 0,927 a 1,083). Conclusão A implantação do SAMU esteve associada a uma redução modesta, mas significativa, na mortalidade intra-hospitalar. Esse achado reforça o papel fundamental do cuidado pré-hospitalar no cuidado do IAM e a necessidade de investimentos nesse serviço para melhorar os desfechos clínicos em países de baixa e média renda.

Abstract Background The effective management of patients with acute myocardial infarction (AMI) is time-dependent. Objectives To assess the impacts of the implementation of prehospital care on admission rates and mortality associated with AMI. Methods Retrospective, ecological study, which assessed data from the Brazilian Universal Health System, from all 853 municipalities of Minas Gerais, from 2008 to 2016. Excessive skewness of general and in-hospital mortality rates was smoothed using the empirical Bayes method. This study assessed the relationship between Mobile Emergency Care Service (SAMU) in each municipality and the following 3 outcomes: mortality rate due to AMI, AMI in-hospital mortality, and AMI hospitalization rate, using the Poisson hierarchical model. Rates were corrected by age structure and detrended by seasonality and temporal influences. A confidence interval of 95% was adopted. Results AMI mortality rates decreased throughout the study, on average 2% per year, with seasonal variation. AMI in-hospital mortality also showed a decreasing trend, from 13.81% in 2008 to 11.43% in 2016. SAMU implementation was associated with decreased AMI mortality (odds ratio [OR] = 0.967, 95% confidence interval [CI] 0.936 to 0.998) and AMI in-hospital mortality (OR = 0.914, 95% CI 0.845 to 0.986), with no relation with hospitalizations (OR = 1.003, 95% CI 0.927 to 1.083). Conclusion SAMU implementation was associated with a modest but significant decrease in AMI in-hospital mortality. This finding reinforces the key role of prehospital care in AMI care and the need for investments on this service to improve clinical outcomes in low- and middle-income countries.

Carga de Doenças Cardiovasculares Atribuível aos Fatores de Risco nos Países de Língua Portuguesa: Dados do Estudo "Global Burden of Disease 2019" / Burden of Cardiovascular Diseases Attributable to Risk Factors in Portuguese-Speaking Countries: Data from the "Global Burden of Disease 2019" Study

Resumo Fundamento: O impacto dos fatores de risco (FR) sobre a morbimortalidade por doença cardiovascular (DCV) na maioria dos países de língua portuguesa (PLP) é pouco conhecido. Objetivo: Analisar a morbimortalidade por DCV atribuível aos FR e sua variação nos PLP de 1990 a 2019, a partir de estimativas do estudo Global Burden of Disease (GBD) 2019. Métodos: Avaliamos as mudanças nos FR ocorridas no período, as taxas de mortalidade e os anos de vida perdidos por incapacidade (DALYs), padronizados por idade, entre 1990 e 2019. Realizou-se a correlação entre a variação percentual das taxas de mortalidade e o índice sociodemográfico (SDI) de cada PLP pelo método de Spearman. O valor p<0,05 foi considerado estatisticamente significativo. Resultados: A pressão arterial sistólica (PAS) elevada foi o principal fator de risco para mortalidade e DALY por DCV para todos os PLP. A mortalidade por DCV mostrou uma tendência de redução em 2019, maior em Portugal (-66,6%, IC95% -71,0 - -61,2) e no Brasil (-49,8%, IC95% -52,5 - -47,1). Observou-se tendência à correlação inversa entre SDI e a variação percentual da mortalidade, que foi significativa para os riscos dietéticos (r=-0,70, p=0,036), colesterol LDL elevado (r=-0,77, p=0,015) e PAS elevada (r=-0,74, p=0,023). Conclusões: Além da PAS, os FR dietéticos e metabólicos justificaram uma maior variação da carga de DCV, correlacionada com o SDI nos PLP, sugerindo a necessidade de adoção de políticas de saúde adaptadas à realidade de cada país, visando a redução de seu impacto sobre a população.

Abstract Background: The impact of risk factors (RF) on morbidity and mortality from cardiovascular disease (CVD) for most Portuguese-speaking countries (PSC) is little known. Objectives: We aimed to analyze the morbidity and mortality from CVD attributable to RF and its variation, from 1990 to 2019, in PSC, based on estimates from the Global Burden of Disease (GBD) 2019 study. Methods: We evaluated changes in cardiovascular RF, mortality rates and age-standardized disability-adjusted life years (DALYs) between 1990 and 2019. The correlation between percentage changes in mortality rates and the sociodemographic index (SDI) of each PSC was evaluated by the Spearman method. A p-value <0.05 was considered statistically significant. Results: Elevated systolic blood pressure (SBP) was the main RF for mortality and DALYs for CVD for all PSC. Mortality from CVD showed a downward trend in 2019, more accentuated in Portugal (-66.6%, 95%CI -71.0 - -61.2) and in Brazil (-49.8%, 95%CI -52.5 - -47.1). There was a trend towards an inverse correlation between SDI and the percent change in mortality, which was significant for dietary risks (r=-0.70, p=0.036), high LDL cholesterol (r=-0.77, p=0.015) and high SBP (r=-0.74, p=0.023). Conclusions: In addition to SBP, dietary and metabolic RF justified a greater variation in the burden of CVD correlated with SDI in the PSC, suggesting the need to adopt health policies adapted to the reality of each country, aiming to reduce their impact on population.

Text Messages to Promote Secondary Prevention after Acute Coronary Syndrome (IMPACS trial)

Abstract Background Short message service (SMS) to promote healthcare improves the control of cardiovascular risk factors, but there is a lack of evidence in low and middle-income countries, particularly after acute coronary syndromes (ACS). Objective This study aims to evaluate whether the use of SMS increases risk factor control after hospital discharge for ACS. Methods IMPACS is a 2-arm randomized trial with 180 patients hospitalized due to ACS at a tertiary hospital in Brazil. Eligible patients were randomized (1:1) to an SMS intervention (G1) or standard care (G2) upon hospital discharge. The primary endpoint was set to achieve 4 or 5 points in a risk factor control score, consisting of a cluster of 5 modifiable risk factors: LDL-C <70mg/dL, blood pressure (BP) <140/90mmHg, regular exercise (≥5 days/week, 30 minutes/session), nonsmoker status, and body mass index (BMI) <25 kg/m2] at 6 months. Secondary outcomes were components of the primary outcome plus rehospitalization, cardiovascular death, and death from any cause. Results are designated as significant if p<0.05. Results From randomized patients, 147 were included in the final analysis. Mean age was 58 (51-64) years, 74% males. The primary outcome was achieved by 12 (16.2%) patients in G1 and 15 (20.8%) in G2 (OR=0.73, 95%CI 0.32-1.70, p=0.47). Secondary outcomes were also similar: LDL-C<70 mg/dl (p=0.33), BP<140/90 mmHg (p=0.32), non-smoker (p=0.74), regular exercise (p=0.97), BMI (p=0.71), and rehospitalization (p=0.06). Death from any cause occurred in three participants (2%), including one cardiovascular death in each group. Conclusion SMS intervention did not significantly improve cardiovascular risk factor control when compared to standard care in patients discharged after ACS in Brazil.

Impact of the COVID-19 pandemic on hospital admissions for cardiovascular diseases in a large Brazilian urban center

Abstract INTRODUCTION: The COVID-19 pandemic has had a great impact on the behavior of individuals and the organization of health systems. This study analyzed the COVID-19 pandemic's effect on public hospitalizations for cardiovascular diseases (CVD) in a large city in Brazil, Belo Horizonte, MG, with approximately 2.5 million inhabitants. METHODS: In a time-series analysis, this study used administrative data from the national "Hospital Information System" from 2010 to February 2020 to estimate the expected number of hospitalizations for CVD by month during the COVID-19 pandemic in Belo Horizonte in 2020 using the Auto-Regressive Integrated Moving Average model. For CVD, this study compared the expected number of hospital admissions, intensive care use, deaths during hospitalization, and mean length of stay with the observed number during the period. RESULTS: There were 6,517 hospitalizations for CVD from March to December 2020, a decrease of 16.3% (95% CI: 4.7-25.3) compared to the projected. The number of intensive care hospitalizations for CVD fell 24.1% (95% CI 13-32.7). The number of deaths also decreased (17.4% [80% CI: 0 - 0.30]), along with the reduction in hospitalizations, as did the length of stay for CVD hospitalizations. These reductions, however, were not significant. CONCLUSIONS: Hospitalizations for CVD were 16.3% lower than expected in a large Brazilian city, possibly due to the fear of getting infected or going to hospitals. Public campaigns informing how to proceed in case of CVD show that prompt urgent attention is essential to mitigate the indirect effects of the pandemic on CVD.

Burden of Cardiovascular diseases attributable to risk factors in Brazil: data from the "Global Burden of Disease 2019" study

Abstract INTRODUCTION: To better understand trends in the main cause of death in Brazil, we sought to analyze the burden of cardiovascular risk factors (RF) and cardiovascular diseases (CVD) attributable to specific RFs in Brazil from 1990 to 2019, using the estimates from the GBD 2019 study. METHODS: To estimate RF exposure, the Summary Exposure Value (SEV) was used, whereas for disease burden attributed to RF, mortality and disability-adjusted life-years (DALY) due to CVD were used. For comparisons over time and between states, we compared age-standardized rates. The sociodemographic index (SDI) was used as a marker of socioeconomic conditions. RESULTS: In 2019, 83% of CVD mortality in Brazil was attributable to RF. For SEV, there was a reduction in smoking and environmental RF, but an increase in metabolic RF. High systolic blood pressure and dietary risks continue to be the main RF for CVD mortality and DALY. While there was a decline in age-standardized mortality rates attributable to the evaluated RF, there was also a stability or increase in crude mortality rates, with the exception of smoking. It is important to highlight the increase in the risk of death attributable to a high body mass index. Regarding the analysis per state, SEVs and mortality attributable to RF were higher in those states with lower SDIs. CONCLUSIONS: Despite the reduction in CVD mortality and DALY rates attributable to RF, the stability or increase in crude rates attributable to metabolic RFs is worrisome, requiring investments and a renewal of health policies.

Staphylococcus aureus Resistente à Meticilina: uma análise da presença na microbiota nasal de estudantes de saúde em período de estágio

Objetivo: A disseminação da resistência bacteriana se tornou o principal obstáculo no tratamento das infecções em todo o mundo. As infecções relacionadas aos cuidados de saúde (IRCS) constituem grande parte do total de infecções diagnosticadas no Brasil. A principal causa para a elevação deste índice é a disseminação bacteriana por profissionais de saúde. O principal patógeno isolado nas IRCS no Brasil é o Staphylococcus aureus e em grande parte dos casos é confirmado seu perfil multirresistente a diversos antibióticos, sendo que algumas destas cepas são denominadas Staphylococcus aureus resistente à meticilina (MRSA). O objetivo deste estudo foi analisar a prevalência de S. aureus e MRSA na microbiota nasal dos acadêmicos de biomedicina, enfermagem e fisioterapia da instituição de ensino superior de Araucária (PR) em período de estágio. Métodos: Foram coletadas amostras de swab nasal de 51 indivíduos, semeadas em ágar manitol salgado 7,5%. As colônias sugestivas de S. aureus tiveram confirmação com bacterioscopia, testes de catalase e coagulase. Após confirmadas, as cepas de S. aureus foram semeadas em ágar cromogênico seletivo e diferencial para MRSA. Resultados: A taxa de colonização nasal por S. aureus foi de 45,1%; destas cepas 91,3% eram MRSA, o que representa 41,2% do total de indivíduos. Conclusão: Os dados alcançados evidenciam a necessidade de vigilância de resistência bacteriana em profissionais e estudantes de saúde para evitar a ocorrência de IRCS.

Objective: The spread of bacterial resistance has become the main obstacle in the treatment of infections worldwide. Healthcare-Associated Infections (HAI) constitute a large part of the total number of infections diagnosed in Brazil and the main cause for these rates is the bacterial spread by healthcare professionals. The main pathogen isolated in the HAI in Brazil is S. aureus and, in most cases, its multi-resistant profile to several antibiotics is confirmed, some of these strains are called Methicillin-resistant Staphylococcus aureus (MRSA). The aim of this study was to analyze the prevalence of S. aureus and MRSA in the nasal microbiota of biomedicine, nursing and physiotherapy students at the Araucária (PR) higher education institution during the internship period. Methods: Nasal swab samples were collected from 51 individuals, sown on mannitol salt agar 7.5%. Colonies suggestive of S. aureus were confirmed with bacterioscopy, catalase and coagulase tests. After confirmed, the strains of S. aureus were sown on selective and differential chromogenic agar for MRSA. Results: The rate of nasal colonization by S. aureus was 45.1%, of these strains 91.3% were MRSA, which represents 41.2% of the total of individuals. Conclusion: The data obtained show the need for surveillance of bacterial resistance in health professionals and students to prevent the occurrence of HAI.

Desafios e importância da avaliação pré-operatória na doença de Peyronie / Challenges and importance of the preoperative evaluation in Peyronie's disease

A doença de Peyronie, notória desde 1743, segue sendo um grande desafio na prática médica, com prevalência relevante e grande impacto na vida sexual dos casais. O tratamento cirúrgico é a principal modalidade terapêutica capaz de restabelecer a vida sexual nos pacientes com doença de Peyronie significativa. A escolha do momento de implementação do tratamento cirúrgico, bem como a escolha da técnica a ser empregada, varia de acordo com três pontos centrais: a fase da doença, a deformidade apresentada e a função erétil. Estes pilares para a decisão terapêutica do paciente com doença de Peyronie possuem nuances, não sendo simples a caracterização destes fatores em muitos casos. Uma avaliação pré-operatória criteriosa, fundamental para a melhor escolha terapêutica, exige experiência e um conhecimento aprofundado sobre o tema. O objetivo do presente artigo é promover uma ampla discussão acerca de fatores primordiais da avaliação pré-operatória de pacientes com doença de Peyronie.

Proteolytic activity of Triatoma infestans saliva associated with PAR-2 activation and vasodilation

Triatoma infestans (Hemiptera: Reduviidae) is a hematophagous insect and the main vector of Trypanosoma cruzi (Kinetoplastida: Trypanosomatidae). In the present study, the authors investigated whether a serine protease activity from the saliva of T. infestans has a role in vasomotor modulation, and in the insect-blood feeding by cleaving and activating protease-activated receptors (PARs). Methods T. infestans saliva was chromatographed as previously reported for purification of triapsin, a serine protease. The cleavage activity of triapsin on PAR peptides was investigated based on FRET technology. Mass spectrometry was used to analyze the sites of PAR-2 peptide cleaved by triapsin. NO measurements were performed using the DAN assay (2,3-diaminonapthalene). The vasorelaxant activity of triapsin was measured in vessels with or without functional endothelium pre-contracted with phenylephrine (3 µM). Intravital microscopy was used to assess the effect of triapsin on mouse skin microcirculation. Results Triapsin was able to induce hydrolysis of PAR peptides and showed a higher preference for cleavage of the PAR-2 peptide. Analysis by mass spectrometry confirmed a single cleavage site, which corresponds to the activation site of the PAR-2 receptor. Triapsin induced dose-dependent NO release in cultured human umbilical vein endothelial cells (HUVECs), reaching a maximum effect at 17.58 nM. Triapsin purified by gel-filtration chromatography (10-16 to 10-9 M) was applied cumulatively to mouse mesenteric artery rings and showed a potent endothelium-dependent vasodilator effect (EC30 = 10-12 M). Nitric oxide seems to be partially responsible for this vasodilator effect because L-NAME (L-NG-nitroarginine methyl ester 300 µM), a nitric oxide synthetase inhibitor, did not abrogate the vasodilation activated by triapsin. Anti-PAR-2 antibody completely inhibited vasodilation observed in the presence of triapsin activity. Triapsin activity also induced an increase in the mouse ear venular diameter. Conclusion Data from this study suggest a plausible association between triapsin activity mediated PAR-2 activation and vasodilation caused by T. infestans saliva.(AU)
