RESUMO
PURPOSE: There is limited literature on the ocular manifestations in patients with psoriasis. Therefore, this study aimed to identify the prevalence of and factors associated with ocular manifestations in adults with psoriasis. METHODS: This cross-sectional study included Brazilian adults with psoriasis. The dermatological evaluation included diagnosis, clinical form, Psoriasis Area and Severity Index (PASI) measurement, and location of the lesions. Patients underwent a full ophthalmological examination, including the Schirmer I test, Rose Bengala staining, and tear breakup time tests. The results were analyzed using chi-square and Pearson's linear correlation tests. RESULTS: Of the 130 patients assessed, 118 (90.8%) exhibited ocular abnormalities, with meibomian gland dysfunction (MGD) being the most prevalent (59.2%), followed by dry eye disease (DED) (56.2%). A significant correlation was observed between MGD and PASI (p = 0.05), and between MGD and certain treatment modalities. DED was significantly associated with PASI (p < 0.05). Concurrent use of acitretin was identified as an independent predictor of MGD (odds ratio [OR] = 3.5, p < 0.05), whereas PASI was a protective factor against DED (OR = 0.39, p < 0.01). CONCLUSION: Given the high prevalence of eye disease among individuals with psoriasis, routine ophthalmological assessments are recommended to prevent possible ocular complications.

BACKGROUND: We described the prevalence of cardiovascular risk factors in groups of Brazilian Indigenous people at different degrees of urbanization. METHODS: The Project of Atherosclerosis among Indigenous populations (Projeto de Aterosclerose em Indígenas; PAI) is a cross-sectional study conducted in Northeast Brazil between August 2016-June 2017. It included three populations: Fulni-ô Indigenous people (lowest degree of urbanization), Truká Indigenous people (greater urbanization), and a highly urbanized non-Indigenous local cohort (control group). Participants were assessed to register sociodemographic, anthropometric, as well as clinical and laboratory-derived cardiovascular (CV) risk parameters. Age-adjusted prevalence of hypertension was also computed. Nonparametric tests were used for group comparisons. RESULTS: Here we included 999 participants, with a predominance of females in all three groups (68.3% Control group, 65.0% Fulni-ô indigenous group, and 60.1% Truká indigenous group). Obesity was present in 45.6% of the urban non-Indigenous population, 37.7% Truká and in 27.6% Fulni-ô participants. The prevalence of hypertension was 29.1% (n = 297) with lower prevalence in the less urbanized Fulni-ô people (Fulni-ô - 18.2%; Truká - 33.9%; and Control - 33.8%; p < 0.001). In the elderly male population, the prevalence of hypertension was 18.7% in the Fulni-ô, 45.8% in the Truká, and 54.5% in the control group. Of the 342 participants that self-reported hypertension, 37.5% (n = 68) showed uncontrolled blood pressure (BP). Uncontrolled BP was more prevalent among Truká people when compared to Fulni-ô people and non-Indigenous participants (45.4%, 22.9%, and 40.7%, respectively; p < 0.001). CONCLUSIONS: We found a higher cardiovascular risk in communities with a higher degree of urbanization, suggesting that living in towns and cities may have a negative impact on these aspects of cardiovascular health.
The lifestyles and environments of traditional indigenous and city-living communities differ. We compared rates of obesity and hypertension in members of two under-studied Indigenous groups in Northeast Brazil and a nearby urbanized group. We found higher rates of obesity and hypertension amongst members of the more urbanized community, suggesting that living in towns and cities may have a negative impact on these aspects of cardiovascular health. These results suggest those living in the city should modify their lifestyle and monitor their cardiovascular health more carefully if possible.
RESUMO
Background Catheter ablation (CA) is a safe, effective, cost-effective technique and may be considered a first-line strategy for the treatment of symptomatic supraventricular tachycardias (SVT). Despite the high prospect of cure and the recommendations of international guidelines in considering CA as a first-line treatment strategy, the average time between diagnosis and the procedure may be long. The present study aims to evaluate predictors related to non-referral for CA as first-line treatment in patients with SVT. Methods and Results The model was derived from a retrospective cohort of patients with SVT or ventricular pre-excitation referred for CA in a tertiary center. Clinical and demographical features were used as independent variables and non-referral for CA as first-line treatment the dependent variable in a stepwise logistic regression analysis. Among 20 clinical-demographic variables from 350 patients, 10 were included in initial logistic regression analysis: age, women, presence of pre-excitation on ECG, palpitation, dyspnea and chest discomfort, number of antiarrhythmic drugs before ablation, number of concomitant symptoms, symptoms' duration and evaluations in the emergency room due to SVT. After multivariable adjusted analysis, age (odds ratio [OR], 1.2; 95% CI 1.01-1.32; P=0.04), chest discomfort during supraventricular tachycardia (OR, 2.7; CI 1.6-4.7; P<0.001) and number of antiarrhythmic drugs before ablation (OR, 1.8; CI 1.4-2.3; P<0.001) showed a positive independent association for non-referral for CA as SVT first-line treatment. Conclusions The independent predictors of non-referral for CA as first-line treatment in our logistic regression analysis indicate the existence of biases in the decision-making process in the referral process of patients who would benefit the most from catheter ablation. They very likely suggest a skewed medical decision-making process leading to catheter ablation underuse.

INTRODUCTION: Asymptomatic patients with moderate functional capacity do not require Coronary Artery Disease (CAD) workup in the preoperative period of non-cardiac surgeries, especially when scheduled for minor and intermediate-risk surgeries. The workup is inappropriate because it promotes over diagnosing and pointless treatments. Moreover, those patients usually undergo cardiology assessment, in addition to pre-anesthetic evaluation. OBJECTIVE: Investigate the role of cardiology consultation as mediator in inappropriate assessment of CAD for preoperative of non-cardiac surgeries. METHOD: Retrospective study performed in a private anesthesia service using medical charts of asymptomatic patients with a history of controlled systemic disease and moderate functional capacity, submitted to pre-anesthetic consultation for minor and intermediate risk surgeries. Cardiology consultations were identified by the presence of a consultation report by a cardiologist. CAD workup was defined as undergoing cardiac stress tests. RESULTS: We included 390 medical charts of patients with mean age of 48.6 ± 15.4 years, 67% women and 69% intermediate risk surgeries. CAD workup was infrequent and performed in 3.9% of patients. Besides, pre-anesthetic evaluation, 93 (24%) patients had a cardiology consultation. Among those patients, 15.1% were submitted to CAD workup, compared to 0.34% of patients without cardiology assessment (p < 0.001; RR = 4.4; 95% CI: 3.5-5.6). CONCLUSIONS: Inappropriate testing for CAD investigation is infrequent for asymptomatic individuals submitted to minor and intermediate risk surgeries. However, cardiology consultation increases substantially the likelihood of a patient undergoing CAD workup, suggesting that, unlike the anesthesiologist, the cardiologist is a major mediator of this kind of management.

BACKGROUND: According to traditional diagnosis thinking, very elderly individuals are more predisposed to develop atypical symptoms in acute coronary syndromes. OBJECTIVE: To test the hypothesis that very elderly individuals are more predisposed to atypical chest pain manifestations due to obstructive coronary artery disease (CAD). METHODS: The Registry of Thoracic Pain includes patients admitted with acute chest pain. Firstly, the typicality index of this clinical manifestation was constructed: the sum of 12 symptom characteristics (8 typical and 4 atypical symptoms). In the subgroup of patients with coronary etiology, the typicality index was compared between octogenarian and non-octogenarian individuals. Statistical significance was defined by p<0.05. RESULTS: 958 patients were included in the registry, and 486 (51%) had a supposedly coronary etiology. In this group, 59 (12%) octogenarians (age 84±3.5, 50% men) were compared to 427 patients aged <80 (60±12 years, 71% men). The typicality index in octogenarians was 3.42±1.92, which is similar to that of non-octogenarians (3.44±1.74; p=0.92 in univariate analysis and p=0.80 after adjustment for sex by analysis of variance - ANOVA). There was also no statistically significant difference when the sample was divided into median age (62 years; 3.41±1.77 vs. 3.49 ± 1.77; p=0.61). There was no statistically significant linear association between age and typicality index (r=- 0.05; p=0.24). Logistic regression analysis for prediction of CAD in the general sample of 958 patients showed no interaction of typicality index with numeric age (p=0.94), octogenarians (p=0.22) or age above median (p=0.74). CONCLUSION: In patients with acute chest pain of coronary etiology, advanced age does not influence the typical clinical presentation.
FUNDAMENTO: De acordo com o pensamento diagnóstico tradicional, indivíduos muito idosos estão mais predispostos a desenvolver sintomas atípicos em síndromes coronarianas agudas. OBJETIVO: Testar a hipótese de que indivíduos muito idosos estão mais predispostos a manifestações de dor torácica atípica devido à doença arterial coronariana obstrutiva (DAC). MÉTODOS: O Registro de dor torácica inclui pacientes internados com dor torácica aguda. Primeiramente, foi construído o índice de tipicidade dessa manifestação clínica: a soma de 12 características de sintomas (8 sintomas típicos e 4 sintomas atípicos). No subgrupo de pacientes com etiologia coronariana, o índice de tipicidade foi comparado entre octogenários e não octogenários. A significância estatística foi definida por p<0,05. RESULTADOS: 958 pacientes foram incluídos no registro, sendo que 486 (51%) tinham etiologia supostamente coronariana. Nesse grupo, 59 (12%) octogenários (idade 84±3,5; 50% homens) foram comparados a 427 pacientes com idade <80 (60±12 anos; 71% homens). O índice de tipicidade em octogenários foi 3,42±1,92, que é semelhante ao de não octogenários (3,44±1,74; p=0,092 na análise univariada e p=0,80 após ajuste para sexo pela análise de variância ANOVA). Também não houve diferença estatisticamente significativa quando a amostra foi dividida em idade mediana (62 anos; 3,41±1,77 vs. 3,49 ± 1,77; p=0,61). Não houve associação linear estatisticamente significativa entre idade e índice de tipicidade (r=- 0,05; p=0,24). A análise de regressão logística para predição de DAC na amostra geral de 958 pacientes não mostrou interação do índice de tipicidade com a idade numérica (p=0,94), octogenários (p=0,22) ou idade acima da mediana (p=0,74). CONCLUSÃO: Em pacientes com dor torácica aguda de etiologia coronariana, a idade avançada não influencia o quadro clínico típico.

BACKGROUND: Simulations are becoming widely used in medical education, but there is little evidence of their effectiveness on neurocritical care. Because acute stroke is a neurological emergency demanding prompt attention, it is a promising candidate for simulation training. OBJECTIVE: To assess the impact of a stroke realistic simulation course on clinicians' self-perception of confidence in the management of acute stroke. METHODS: We conducted a controlled, before-after study. For our intervention, 17 healthcare professionals participated in a stroke realistic simulation course. As controls, participants were chosen from a convenience sample of attendees to the courses Emergency Neurologic Life Support (ENLS) (18 participants) and Neurosonology (20 participants). All participants responded pre- and post-test questionnaires evaluating their self-perception of confidence in acute stroke care, ranging from 10 to 50 points. We evaluated the variation between pre- and post-test results to assess the change on trainees' self-perception of confidence in the management of acute stroke. Multivariate analysis was performed to control for potential confounders. RESULTS: Forty-six (83.63%) subjects completed both questionnaires. The post-test scores were higher than those from the pretests in the stroke realistic simulation course group [pretest median (interquartile range - IQR): 41.5 (36.7-46.5) and post-test median (IQR): 47 (44.7-48); p=0.033], but not in the neurosonology [pretest median (IQR): 46 (44-47) and post-test median (IQR): 46 (44-47); p=0.739] or the ENLS [pretest median (IQR): 46.5 (39-48.2), post-test median (IQR): 47 (40.2-49); p=0.317] groups. Results were maintained after adjustment for covariates. CONCLUSIONS: This stroke realistic simulation course was associated with an improvement on trainees' self-perception of confidence in providing acute stroke care.

OBJECTIVES: Healthcare professionals need to take into account their knowledge, skills and attitudes to develop a focused clinical question, perform an effective search of the literature, critically appraise the evidence, and apply to the clinical context and evaluate the effectiveness of the process. To date, there is a lack of consensus on evidence-based medicine (EBM) curriculum for undergraduate healthcare students in Brazil. The aim of this study was to develop a consensus on EBM curriculum contents for healthcare schools in Brazil considering expert opinion. DESIGN: Modified three-round Delphi methodology. SETTING: Online survey. PARTICIPANTS: The expert panel was composed of 40 healthcare professionals from different specialties. Most of the participants (n=24; 60%) were female with the age between 30 and 44 years. Participants were also experts in the field of epidemiology, biostatistics or public health. The mean experience of experts in teaching EBM was 9.5 years. MAIN OUTCOME MEASURES: An online questionnaire consisting of 89 items related to EBM was sent to the experts. The experts ranked each item of EBM curriculum considering the importance of each item as omitted, mentioned, explained or practised. The last section of the questionnaire was composed of 'additional content' where the experts evaluated only if an item should be included or not, the form of offering the EBM contents and the total workload (in hours/semester). Open-ended questions were present in each section to give the opportunity to experts to insert suggestions. Items that reached values greater than or equal to 70% of agreement among experts was considered definitive for the curriculum. Items between 51% and 69% of agreement were included for the next round and those items with less than or equal to 50% of agreement were considered unnecessary and were excluded. In the third round, the EBM contents were classified according to the degree of consensus as follow: strong (≥70% of agreement), moderate (51%-69% of agreement) and weak (50% of agreement) based on the maximum consensus reached. RESULTS: Of the 89 initial contents, 32 (35.9%) reached a strong degree of consensus, 23 (25.8%) moderate degree of consensus, two (2.2%) weak degree of consensus and 35 items were not recommended (≤50% of agreement). The workload suggested by experts should be between 61 and 90 hour/semester and an EBM curriculum should be offered with epidemiology and biostatistics as prerequisites. Regarding the importance of each item, 29 (72.5%) should be explained and 25 (27.5%) should be practised with exercises. CONCLUSIONS: The consensus on an EBM curriculum for Brazilian healthcare schools consists of 54 items. This EBM curriculum also presents the degree of consensus (strong, moderate and weak), the importance of each item (mentioned, explained and practised with exercises). A total workload of between 60 and 90 hours per semester was suggested and the EBM curriculum should be offered with epidemiology and biostatistics as prerequisites, but also EBM contents should be included within other disciplines throughout the entire undergraduate course.

INTRODUCTION: The practice of unnecessary conduct and waste in Health is an important topic, not often addressed during undergraduate training. Medical education has a fundamental role in student and doctors' training concerning cost-conscious attitudes for good health care. The aim of this study was to describe and assess the implementation of the Choosing Wisely campaign within a General Surgery residency program. MATERIAL AND METHODS: This was an interventional study involving residency advisors and specialty residents. Recommendations based on three procedures frequently used in clinical practice, with no benefits and involving unnecessary risks for patients were identified by residency advisors with the use of the Delphi method and were grouped by frequency and by nature according to the Choosing Wisely layout. Educational actions such as workshops and banner advertising in addition to training activities regarding cost-conscious healthcare were carried out. This subject was also included in the theoretical evaluation of the residency program. RESULTS: The leading five recommendations were related to (i) computed tomography overuse (versus ultrasound imaging) in patients with suspected acute appendicitis, (ii) multithreaded computed tomography overuse in patients with low-risk trauma, (iii) longer than recommended antibiotic prophylaxis in surgical patients, (iv) longer than recommended preoperative fasting period and (v) upper gastrointestinal endoscopy overuse in surgical patients without an adequate clinical evidence or without the presence of warning signs. Awareness and reflection among participants were improved, leading to high grades in final evaluation. DISCUSSION: Changes in training regarding quality of care and cost awareness should start throughout undergraduate training, within a learning environment focused on a reflective and evidence-based practice. All the benefits and harms to patients were taken into account in the recommendations that emerged from this study. CONCLUSION: The inclusion of this initiative in the General Surgery residency, involving reflective discussions on campaign recommendations regarding procedures frequently used in clinical practice, with no benefits and involving unnecessary risks for patients may lead to more cost-conscious procedures.
Introdução: A prática de condutas desnecessárias e os desperdícios na saúde são temas importantes e ainda pouco abordados no curso de Medicina. A educação médica tem um papel fundamental na formação de estudantes e médicos com atitudes custo-conscientes para uma boa atenção à saúde. O objectivo deste estudo foi descrever e avaliar a implementação do programa Choosing Wisely - Escolhas Criteriosas em Saúde, no internato de Cirurgia Geral.Material e Métodos: Estudo de intervenção envolvendo orientadores de formação e internos. Utilizando a técnica Delphi, os orientadores de formação identificaram três intervenções frequentemente observadas na prática clínica sem benefício e com potenciais riscos desnecessários para o doente, que geraram recomendações, agrupadas e adaptadas ao formato do programa Choosing Wisely. O tema foi incluido na avaliação do internato, tendo sido desenvolvidas ações de formação e de divulgação em banners personalizados, a par de atividades de aprendizagem reflexiva sobre o programa e da integração da temática na avaliação teórica do internato.Resultados: As cinco principais recomendações referem-se (i) à utilização excessiva de tomografia axial computorizada na abordagem da suspeita de apendicite aguda e (ii) de tomografia axial computorizada de vários segmentos do corpo em traumatismos de baixo grau de gravidade, (iii) profilaxia antibiótica mais prolongada do que o recomendado no doente cirúrgico, (iv) jejum mais prolongado do que o recomendado no pré-operatório de todas as cirurgias e (v) utilização excessiva da endoscopia digestiva alta em doentes cirúrgicos sem sinais clínicos de alarme. As ações de formação geraram um incremento da sensibilização e reflexão, traduzido globalmente por um elevado aproveitamento na avaliação final.Discussão: A formação em escolhas criteriosas em saúde, promovendo uma utilização de cuidados de saúde consciente e de qualidade, sugere que as mudanças devem ocorrer ao longo do curso de Medicina, num ambiente de aprendizagem centrado numa prática reflexiva e baseada na evidência. As recomendações produzidas no estudo tiveram em consideração a totalidade dos benefícios e riscos para o doente.Conclusão: A integração da iniciativa Choosing Wisely no programa de formação em Cirurgia Geral deu origem a um conhecimento e discussão mais reflexivos sobre as recomendações relativas à utilização racional e criteriosa de cuidados de saúde, podendo resultar numa prática médica mais sustentável e sensível aos custos que gera.

Introdução: O Echo WISELY Trial é um estudo controlado, randomizado, multicêntrico, cego pelo investigador, que avaliou uma intervenção educacional com base nos critérios de uso apropriado para ecocardiografia para redução da proporção de ecocardiogramas raramente apropriados realizados ambulatorialmente. Objetivo: Descrever a prevalência e identificar preditores de responsividade de médicos respondedores submetidos à intervenção educacional no Echo WISELY Trial. Métodos: Médicos do grupo intervenção receberam um programa educacional multifacetado. O médico respondedor foi definido como aquele que apresentou redução >2,5% na média proporcional de exames raramente apropriados solicitados entre o primeiro trimestre (linha de base) e qualquer um dos seguintes trimestres (segundo ao sexto). Foram comparadas as características do médico (sexo, tempo de formação, especialidade médica e local de trabalho) com as classificações dos ecocardiogramas (apropriado, talvez apropriado e raramente apropriado) e razões clínicas para ecocardiogramas solicitados utilizando teste do qui-quadrado. A significância estatística foi indicada por p < 0,05 bicaudal. Resultados: Foram analisados 4.605 exames solicitados nos seis hospitais participantes de Ontário e randomizados para o braço intervenção. Dentre os 36 médicos incluídos, 26 (72%) foram classificados como respondedores. Entre as variáveis analisadas, não houve diferença significativa entre médicos respondedores e não respondedores à intervenção educacional. O número de exames raramente apropriados solicitados pelos respondedores foi significativamente menor que o de não respondedores (234; 8,67% versus 261; 13,8%; p < 0,0001). Conclusão: A prevalência de médicos respondedores é alta, porém não foram identificados preditores de responsividade à intervenção educacional entre as variáveis analisadas. Isso pode decorrer de aspectos psicológicos e características pessoais dos médicos, que não foram incluídos nesta pesquisa.(AU)
Introduction: The Echo WISELY Trial is a controlled randomized multicenter investigator-blinded study that evaluated an educational intervention based on the criteria for appropriate use of echocardiography to reduce the proportion of rarely appropriate outpatient echocardiograms performed. Objective: To describe the prevalence and identify predictors of the responsiveness of responding physicians subjected to an educational intervention in the Echo WISELY Trial. Methods: The intervention group physicians received a multifaceted educational program. A responding physician was defined as one who had a >2.5% reduction in the proportional mean of rarely appropriate tests requested between the first trimester (baseline) and any of the following trimesters (second to sixth). Physician characteristics (sex, time since graduation, medical specialty, and workplace) were compared to the echocardiogram ratings (appropriate, maybe appropriate, and rarely appropriate) and clinical reasons for the requested echocardiograms using the chi-square test. Statistical significance was indicated by a two-tailed p < 0.05. Results: A total of 4,605 tests requested at the six participating hospitals in Ontario were analyzed and randomized for the intervention arm Of the 36 included physicians, 26 (72%) were classified as responders. Of the variables analyzed, there was no significant difference in the outcomes of the responders versus non-responders to the educational intervention. The number of rarely appropriate tests requested by the responders was significantly lower than that of the non-responders (234 [8.67%] versus 261 [13.8%]; p < 0.0001). Conclusion: The prevalence of responder physicians was high, but predictors of responsiveness to educational intervention were not identified among the analyzed variables. This may be a result of the psychological aspects and personal characteristics of the physicians, which were not included in this research. (AU)

Fundamento: O processo de urbanização tem impacto na carga de doenças cardiovasculares. As populações indígenas podem sofrer uma transição epidemiológica devastadora. Objetivos: Descrever o protocolo de estudo do Projeto de Aterosclerose nas Populações Indígenas (PAI) para avaliar a análise ecocardiográfica e as doenças cardiovasculares (CV) subclínicas em populações indígenas de acordo com o grau de urbanização e mostrar resultados preliminares do estudo piloto. Métodos: O PAI é um estudo transversal, com voluntários com idade entre 30 e 70 anos, em grupos indígenas brasileiros expostos a estágios baixos e avançados de urbanização (Fulni-ô e Truká, respectivamente) e um grupo controle urbano, excluindo indivíduos com doenças CV conhecidas ou em hemodiálise. O estudo piloto começou no território de Fulni-ô em setembro de 2016. Os participantes foram submetidos a avaliação clínica e laboratorial, eletrocardiograma (ECG), ultrassonografia de carótidas e um protocolo ecocardiográfico abrangente, incluindo strain longitudinal global (SLG) avaliado por speckle tracking. Os resultados preliminares são descritos de acordo com o sexo em uma análise univariada. Resultados: O estudo piloto avaliou o protocolo descrito em 55 indivíduos do grupo indígena Fulni-ô (48,7 ± 12,0 anos, 80% mulheres). Foram encontrados fatores de risco tradicionais como hipertensão, diabetes e dislipidemia em 40%, 36% e 54%, respectivamente, sem diferenças estatísticas significativas entre os sexos. O uso de tabaco mostrou-se extremamente prevalente, referido em 91% dos participantes. Os parâmetros derivados da ecocardiografia estavam, em média, dentro da faixa normal. No entanto, a média do SLG foi de 17,3 ± 3,4% (p 0,73 por sexo). Conclusão: Descrevemos o protocolo do estudo PAI para avaliar doenças cardiovasculares subclínicas e fatores de risco em populações indígenas de acordo com o estágio de urbanização. Resultados preliminares sugerem alta prevalência desses na população indígena em menor grau de urbanização.
Background: The urbanization process impacts the burden of cardiovascular disease (CVD). Indigenous populations can undergo a devastating epidemiological transition. Objective: The present study aimed to describe the Project of Atherosclerosis among Indigenous Populations (PAI) study protocol for assessing echocardiographic images and subclinical CVD in indigenous populations according to the degree of urbanization and report its preliminary results. Methods: The PAI is a cross-sectional study that includes volunteers aged 3070 years among Brazilian indigenous groups exposed to low and advanced stages of urbanization (Fulni-ô and Truká, respectively) and an urban control group. Individuals with known CVD or who were on hemodialysis were excluded. The pilot study began in Fulni-ô territory in September 2016. The participants underwent clinical and laboratory

Fundamento: O acidente vascular encefálico (AVE) é prevalente no mundo. Reconhecimento precoce da doença cardiovascular subclínica pode predizer um primeiro episódio de AVE isquêmico; o speckle tracking associado à ecocardiografia (STE) permite detecção precoce da disfunção miocárdica subclínica. Objetivo: Provar a associação entre deformação miocárdica avaliada pelo STE e primeiro episódio de AVE em indivíduos saudáveis. Método: Incluímos participantes entre 40-80 anos com primeiro episódio de AVE isquêmico sem cardiopatia conhecida, pareados por sexo, idade e hipertensão com grupo controle saudável na proporção 1:2. STE avaliou strain longitudinal (SL) do ventrículo esquerdo (VE), e ecocardiografia tradicional foi realizada. Análises univariada e multivariada avaliaram as relações do AVE com fatores de risco cardiovasculares e parâmetros derivados da ecocardiografia. Resultado: 29 casos e 62 controles foram incluídos. Média etária foi 60 ± 12 anos; 54% eram homens. Tabagismo foi mais prevalente em casos do que em controles (34% vs. 9%; p=0.001). Nenhum outro fator de risco evidenciou diferença estatística. Casos tiveram menor deformação miocárdica comparados aos controles (SL -16.7 ± 3.4% vs. -19.2 ± 2.8%; p < 0.001). Não houve diferença em relação aos parâmetros ecocardiográficos tradicionais. Após ajuste para tabagismo e hiperlipidemia, SL manteve-se independentemente associado com AVE (OR=1.3; 95% CI, 1.1 1.6; p=0.005). A área abaixo à curva ROC para AVE aumentou significativamente após adicionar SL ao tabagismo (0.65 para 0.78, respectivamente; p=0.009). Conclusão: SL tem independente associação com o primeiro episódio de AVE isquêmico em adultos de média idade com corações geralmente normais. SL pode ser potencial marcador de risco nesta população
Background: Stroke is prevalent worldwide, and early recognition of subclinical cardiovascular (CV) disease could predict a first ischemic stroke (IS) episode. Speckle-tracking echocardiography (STE) allows the detection of early subclinical myocardial dysfunction. Aim: To examine the association between myocardial deformation, evaluated by STE, and first episode of IS in a sample of otherwise healthy patients. Methods: We included individuals between 4080 years old, with a first incidence of IS, with no known CV disease, matched to healthy controls by sex, age, and hypertension at a 1:2 ratio. STE was used to assess LV global longitudinal strain (GLS), and traditional echocardiography was performed. Univariate and multivariable analyses were performed to assess the relationship among stroke, CV risk factors, and echocardiographyderived parameters. Results: A total of 29 cases and 62 controls were included. The mean age of the patients was 60 ± 12 y/o, and 54% were males. Smoking was more prevalent in cases compared to controls (34% vs. 9%; p = 0.001), and there were no significant differences in the other examined risk factors. Cases had less myocardial deformation compared to controls (GLS: -16.7% ± 3.4% vs. -19.2 ± 2.8%; p < 0.001), and there was no

PURPOSE: To test the predictive value of ophthalmic artery (OA) Doppler velocimetry in relation to the occurrence of hypertensive disorders of pregnancy (HDP). METHODS: We compared, by analysis of variance, the values of seven OA Doppler variables (peak systolic velocity, second systolic peak velocity [P2], mean velocity, end diastolic velocity, resistance index [RI], pulsatility index [PI], and peak ratio) of 31 women with preeclampsia and 33 women with gestational hypertension vs those of 227 women without HDP. The prognostic value of these variables in relation to the occurrence of HDP was evaluated by the area under the curve (AUC) receiver operating characteristic curve. RESULTS: All OA Doppler variables except RI and PI showed significant (P < .5) differences between groups. After adjustment for confounders, only P2 was an independent predictor of HDP (P < .001), with an AUC of 0.76. The best cut-off point for predicting HDP was P2 ≥ 21.4 cm/s, with sensitivity 69%, specificity 78%, positive likelihood ratio 3.1, negative likelihood ratio 0.4, positive predictive value 47%, and negative predictive value 90%. P2 improved the predictive ability of a model based on clinical variables, incrementing AUC from 0.77 to 0.84 in the final model containing clinical and Doppler variables. CONCLUSION: The elevation of OA P2 in the second trimester of pregnancy is an independent predictor of hypertensive disorders, and improves the discriminatory ability of clinical markers.

OBJECTIVE: To evaluate the effect of early use of a cycle ergometer, compared to a standard care protocol, in postoperatory in-hospital mobility following cardiac surgery. DESIGN: A randomized controlled trial. SETTING: Tertiary hospital in Salvador, Bahia, Brazil. SUBJECTS: Patients submitted to elective cardiac surgery (valvular or coronary bypass surgery by sternotomy). INTERVENTION: Patients were randomly allocated in two groups: (1) cycle ergometer training group (10-minute session) and (2) control group submitted standard physiotherapy protocol (10-minute session). Training was provided twice a day, immediately following extubation and until patient was discharged from the intensive care. MAIN MEASURES: The primary outcome was the difference in the total number of steps recorded on the pedometer over three days. Secondary outcomes were mobility in different subgroups and the reasons that prevented individuals from walking during early cardiac rehabilitation. RESULTS: A total of 228 participants completed the study. No significant difference was found in the total number of steps between the groups after intervention: 2183 (range: 1729-2772) in the intervention group versus 2006 (1517-2657) in the control group (P = 0.167). However, self-reports indicated better motivation in the intervention group (P = 0.044). No adverse events occurred during the study. CONCLUSION: As a strategy for early mobilization following cardiac surgery, the use of a cycle ergometer failed to increase independent physical activity compared to a standard care protocol. Nevertheless, it was safe and could be an alternative to make rehabilitation more attractive and motivational for this patient population.

Abstract: Objective: to evaluate the implementation of the Choosing Wisely (CW) campaign strategies at a medical clinic internship. Methods: This interventional study involved internship teachers and students, using online questionnaires on the SurveyMonkey platform, and face-to-face activities. Using the Delphi technique, teachers identified three unnecessary situations that commonly occur in practice. The recommendations were grouped by frequency and subject, adapted to the CW format. A Likert scale was used to classify the specialists' opinion aiming to obtain the final list of recommendations. Before the introduction of the CW campaign, we conducted an Objective Structured Clinical Examination (OSCE). Two groups of students were compared: one group that underwent the same OSCE evaluation before the implementation of the CW campaign (110), and another group that participated of all educational actions (n = 98). The CW campaign was implemented by developing educational actions using the recommendations during workshops, banners, and theoretical evaluation, in addition to an Objective Structured Clinical Examination (OSCE). Results: after grouping the recommendations, 24 items remained. The specialists selected eight recommendations by frequency, addressing unnecessary behaviors such as requesting multiple exams, overuse of non-hormonal anti-inflammatory drugs, the indication of digestive endoscopy in younger patients with dyspepsia, excessive chest X-rays in intensive care unit, prescribing antibiotic prophylaxis for longer than recommended, routine indication of allergic tests, inadequate initial screening for thyroid assessment, and spirometry in asymptomatic patients. The educational actions resulted in a process of awareness and discussion among the participants, evidenced by theoretical evaluation (> 95%), as well as in the OSCE, where the level of successes was higher in the exposed group when compared to the nonexposed group (p = 0.001). Conclusion: the implementation of the CW campaign improved the clinical skills of medical clinic internship students and allowed positive discussions about cost-consciousness in health.
Resumo: Objetivo: avaliar a implementação de estratégias da campanha Choosing Wisely (CW) no internato de clínica médica. Métodos: Este estudo de intervenção envolveu professores e alunos do internato, por meio de questionários on-line na plataforma SurveyMonkey e atividades presenciais. Usando a técnica Delphi, os professores identificaram três situações desnecessárias que geralmente ocorrem na prática. As recomendações foram agrupadas por frequência e assunto e adaptadas ao formato CW. Utilizou-se uma escala Likert para classificar a opinião dos especialistas, obtendo-se a lista final de recomendações. Antes da introdução da campanha da CW, realizamos um Exame Clínico Objetivo Estruturado (OSCE). Foram comparados dois grupos de estudantes: um grupo que realizou a avaliação OSCE antes da implantação da campanha CW (110) e outro que participou de todas as ações educativas (n = 98). Implementamos a campanha da CW, desenvolvendo ações educativas usando as recomendações durante oficinas, banners e avaliação teórica, além de um Exame Clínico Objetivo Estruturado (OSCE). Resultados: após o agrupamento das recomendações, restaram 24 itens. Os especialistas selecionaram oito recomendações, abordando comportamentos desnecessários como solicitação de vários exames, uso excessivo de anti-inflamatórios não hormonais, indicação de endoscopia digestiva para pacientes mais jovens com dispepsia, excesso de radiografia de tórax em unidade de terapia intensiva, prescrição de profilaxia antibiótica por mais tempo do que o recomendado, indicação de rotina de testes alérgicos, triagem inicial inadequada para avaliação da tireóide e espirometria em pacientes assintomáticos. As ações educativas resultaram em conscientização e discussão entre os participantes, evidenciado por meio de avaliação teórica (> 95%), bem como no OSCE, onde o nível de sucessos foi maior no grupo exposto quando comparado ao grupo não exposto (p = 0,001). Conclusão: a implementação da campanha CW melhorou as habilidades clínicas dos estudantes do internato em clínica médica e permitiu discussões positivas sobre custo-consciência em saúde.
