ABSTRACT

Abstract Objective: Stroke is an important cause of disability and death in adults worldwide. However, it is preventable in most cases and treatable as long as patients recognize it and reach capable medical facilities in time. This community-based study investigated students' stroke knowledge, Emergency Medical Services (EMS) activation, associated risk factors, warning signs and symptoms, and prior experience from different educational levels in the KIDS SAVE LIVES BRAZIL project. Methods: The authors conducted the survey with a structured questionnaire in 2019‒2020. Results: Students from the elementary-school (n = 1187, ~13 y.o., prior experience: 14%, 51% women), high-school (n = 806, ~17 y.o., prior experience: 13%, 47% women) and University (n = 1961, ~22 y.o., prior experience: 9%, 66% women) completed the survey. Among the students, the awareness of stroke general knowledge, associated risk factors, and warning signs and symptoms varied between 42%‒66%. When stimulated, less than 52% of the students associated stroke with hypercholesterolemia, smoking, diabetes, and hypertension. When stimulated, 62%‒65% of students recognized arm weakness, facial drooping, and speech difficulty; only fewer identified acute headache (43%). Interestingly, 67% knew the EMS number; 81% wanted to have stroke education at school, and ~75% wanted it mandatory. Women, higher education, and prior experience were associated with higher scores of knowing risk factors (OR = 1.28, 95% CI: 1.10‒1.48; OR = 2.12, 95% CI: 1.87‒2.40; OR = 1.46, 95% CI: 1.16‒1.83; respectively), and warning signs- symptoms (OR = 2.22, 95% CI: 1.89‒2.60; OR = 3.30, 95% CI: 2.81‒3.87; OR = 2.04, 95% CI: 1.58‒2.63; respectively). Conclusion: Having higher education, prior experience, and being a woman increases stroke-associated risk factors, and warning signs and symptoms identification. Schoolchildren and adolescents should be the main target population for stroke awareness. HIGHLIGHTS Higher education, prior experience, and being women improved the odds of identifying stroke warning signs and symptoms as associated risk factors Improving knowledge, skills, and attitude on acute stroke in the school community may represent a significant advance in public health management Future stroke awareness campaigns and educational efforts should focus on schoolchildren and adolescents, especially in low-income countries

ABSTRACT

Introdução A cirurgia de revascularização do miocárdio (CRM) é uma das mais frequentes cirurgias realizadas em todo o mundo, muitos estudos vêm relatando os benefícios do treinamento físico para a melhora da capacidade funcional, porém há poucos estudos sobre os efeitos na função endotelial vascular. Objetivo Analisar os efeitos do treinamento físico sobre a função endotelial vascular em pacientes submetidos à CRM, isoladamente na fase tardia da reabilitação após seis meses de programa de reabilitação cardíaca (PCR). Métodos Foram incluídos pacientes que haviam sido submetidos à CRM no período máximo de um ano após a cirurgia. O PRC foi empregado durante seis meses consecutivos, com três sessões semanais. Todos os pacientes realizaram exames laboratoriais, teste de força muscular de uma repetição máxima (1-RM) para os membros superiores e inferiores, teste de caminhada de 6 min (TC6M) e avaliação da função endotelial através da técnica de vasodilatação mediada pelo fluxo. Resultados Onze pacientes iniciaram o PRC, porém nove pacientes o completaram. A média de idade foi de 66 anos (50 a 82 anos) e o sexo masculino foi predominante (55,6%). Houve mudanças significativas nos exames laboratoriais bioquímicos: aumento do colesterol total (Basal: 162 ± 31mg/dL vs. 195 ± 39mg/dL; P=0,012) e diminuição da hemoglobina glicada (Basal: 6,74 ± 1,64% vs. 6,26 ± 1,62%; P=0,028). A força muscular aumentou significativamente nos membros superiores e inferiores (P=0,030 e P=0,038, respectivamente); no TC6M observou-se um aumento significativo de 20% na distância percorrida (P=0,020) após seis meses consecutivos de treinamento e houve uma melhora na vasodilatação mediada pelo fluxo (Basal: 6,35 ± 3,92% vs. 6 meses: 9,90 ± 4,19%; P=0,026). Conclusão O treinamento combinado realizado em seis meses ajudou a melhorar a função endotelial e a capacidade funcional de pacientes sedentários que foram submetidos à CRM na fase tardia da reabilitação.


Introduction The coronary artery bypass graft surgery (CABG) is one of the most common surgeries performed worldwide, many studies have reported the benefits of physical training to improve functional capacity, however there are few studies about the effect of this training on vascular endothelial function. Objective To analyze the effects of physical training on vascular endothelial function in patients who underwent CABG surgery alone in the last phase of rehabilitation after six months of cardiac rehabilitation program (CRP). Methods Patients who underwent CABG surgery in a maximum period of one year after surgery were included in the study. The CRP was carried out during six consecutive months, with three sessions per week. All patients underwent biochemical blood tests, muscle strength testing of one repetition maximum (1-RM test) for upper and lower limbs, 6-minute walk test (6MWT), and evaluation of endothelial function through the flow-mediated vasodilation technique. Results Eleven patients started CRP, but only nine patients completed it. The mean age was 66 years old (50 to 82 years old), males being predominant (55.6%). There were significant changes in biochemical laboratory tests: increase on total cholesterol (Baseline: 162 ± 31mg/dL vs. 195 ± 39mg/dL; P=0.012), and decrease on glycated hemoglobin (Baseline: 6.74 ± 1.64% vs. 6.26 ± 1.62%; P=0.028). Muscle strength was significantly increased in upper and lower limbs (P=0.030, and P=0.038, respectively) and in 6MWT we observed a significant increase of 20% in distance traveled (P=0.020) after six consecutive months of training. There was also a flow-mediated vasodilation improvement (6.35 ± 3.92% vs. 9.90 ± 4.19%; P=0.026). Conclusion The combined training carried out in six months helped to improve endothelial function and functional capacity in sedentary patients submitted to CABG surgery in the last phase of cardiac rehabilitation.

ABSTRACT

Atualmente, a obesidade é considerada o maior problema de saúde pública do mundo, já atingindo características epidêmicas, segundo a Organização Mundial da Saúde. O acúmulo excessivo de peso é o maior fator de risco, associado a diversas doenças, como diabetes mellitus tipo 2, hipertensão, dislipidemias e doenças osteometabólicas, como osteoporose e osteoartrite. A osteoartrite é a doença reumática mais prevalente, e a principal causa de incapacidade física e diminuição da qualidade de vida da população acima de 65 anos. Acomete principalmente as articulações que suportam peso, como joelhos e quadris. No entanto, juntamente com os casos de obesidade, sua prevalência vem aumentando e em outras articulações, como as das mãos. Assim, supõe-se que a influência da obesidade no desenvolvimento da osteoartrite esteja além da sobrecarga mecânica. O objetivo desta revisão foi correlacionar os possíveis mecanismos que determinam a gênese e o desenvolvimento dessas duas doenças. O aumento da massa adiposa é diretamente proporcional ao consumo exagerado de ácidos graxos saturados, responsáveis pela condição sistêmica de inflamação de baixo grau e resistência à insulina e à leptina. Em níveis elevados, a leptina assume características inflamatórias e age na cartilagem articular, desencadeando o processo inflamatório e alterando a homeostase desse tecido com consequente degeneração. Conclui-se que a obesidade é um fator de risco para a osteoartrite e que a prática de atividade física e modificações na composição da dieta podem reverter o quadro inflamatório e a resistência à leptina, atenuando a progressão ou prevenindo o surgimento da osteoartrite.


Obesity is currently considered a major public health problem in the world, already reaching epidemic characteristics, according to the World Health Organization. Excess weight is the major risk factor associated with various diseases, such as type 2 diabetes mellitus, hypertension, dyslipidemia and osteometabolic diseases, including osteoporosis and osteoarthritis. Osteoarthritis is the most prevalent rheumatic disease and the leading cause of physical disability and reduced quality of life of the population over 65 years. It mainly involves the joints that bear weight - knees and hips. However, along with the cases of obesity, its prevalence is increasing, and even in other joints, such as hands. Thus, it is assumed that the influence of obesity on the development of OA is beyond mechanical overload. The purpose of this review was to correlate the possible mechanisms underlying the genesis and development of these two diseases. Increased fat mass is directly proportional to excessive consumption of saturated fatty acids, responsible for systemic low-grade inflammation condition and insulin and leptin resistance. At high levels, leptin assumes inflammatory characteristics and acts in the articular cartilage, triggering the inflammatory process and changing homeostasis this tissue with consequent degeneration. We conclude that obesity is a risk factor for osteoarthritis and that physical activity and changes in diet composition can reverse the inflammatory and leptin resistance, reducing progression or preventing the onset of osteoarthritis.

ABSTRACT

INTRODUÇÃO: Os programas de reabilitação cardíaca (PRC) vêm diminuindo a morbidade e a mortalidade em pacientes após cirurgias de revascularização do miocárdio (CRM). OBJETIVO: Observar a adesão de pacientes submetidos à CRM isoladamente na fase tardia a um PRC e analisar a qualidade de vida e capacidade funcional antes e após o treinamento físico de três meses de PRC. MÉTODOS: Foram contatados todos os pacientes submetidos à CRM isoladamente no período de um ano para participarem de um PRC com duração de três meses com três sessões semanais de uma hora de duração. Todos os pacientes realizaram exames bioquímicos de sangue, teste de força muscular de uma repetição máxima (1-RM) para membros superiores e inferiores, teste de caminhada dos 6 minutos (TC6) e responderam o questionário de qualidade de vida SF-36 antes e após o treinamento. RESULTADOS: De todos os 86 pacientes contatados, apenas 13% (n = 11) concluíram o PRC. A média de idade foi 67 ± 9 anos. O sexo masculino foi predominante, 73% (oito homens). Não houve alterações significativas nos exames bioquímicos laboratoriais. No TC6 houve um aumento significativo na distância percorrida (p = 0,014); quanto à força muscular houve um aumento significativo na carga para o teste em membros superiores (p = 0,043); e no questionário SF-36 não observamos diferenças significativas nos escores antes e depois dos três meses de PRC. CONCLUSÃO: A adesão ao PRC foi baixa, logo é de suma importância a divulgação da participação de pacientes que realizaram CRM nesses programas para proporcionar maior capacidade funcional. .


INTRODUCTION: The Cardiac Rehabilitation Programs (CRP) is decreasing the morbidity and mortality in patients after coronary artery bypass graft (CABG). OBJECTIVE: To observe the adherence of patients undergoing CABG alone in late phase to a PRC and analyze the quality of life and functional capacity before and after physical training in a period of three months. METHODS: We contacted all patients undergoing CABG alone in the period of one year to participate in a CRP lasting three months with three weekly sessions of one hour duration. All patients underwent biochemical blood tests, one-repetition maximum test (1RM) for the muscular strength in upper and lower limbs, 6-minute walk test (6MWT) and completed the quality of life questionnaire (SF-36) before and after training. RESULTS: In all 86 patients contacted, only 13% (n=11) patients completed the CRP. The mean age was 67 ± 9 years, predominantly male, 73% (8 men). There were no significant differences in the biochemical laboratory tests, however in 6MWT we observed significant increase in distance walked (p=0.014), a significant increase in muscle strength in the upper limbs (p=0.043), and in the SF-36, there were no significant differences in the scores before and after three months of CRP. CONCLUSION: Adherence to the CRP was low, so it is of paramount importance to disclose the participation of patients who underwent CABG in these programs to provide greater functional capacity. .

ABSTRACT

OBJECTIVE: To analyze the results of isolated on-pump coronary artery bypass graft surgery (CABG) in patients > 65 years-old. METHODS: Patients undergoing isolated on-pump CABG from December 1st 2010 to July 31th 2012 were divided in two groups: GE (elderly > 65 years-old, n=103) and GA (adults < 65 years-old, n=150). Preoperative data, intraoperative (as cardiopulmonar bypass time, aortic clamping time, time length of stay in mechanical ventilation - MV - and number of grafts), and postoperative variable (as morbidity, mortality and time length of stay in hospital) were analyzed during hospitalization. RESULTS: In GE, the morbidity rate was greater than in GA (30% vs. 14%, P=0.004), but there was no difference in the mortality rate (5.8% vs. 2.0%, P=0.165). In GA, there was higher prevalence DM (39.6% vs. 27%, P=0.043) and smoking (32.2% versus 19.8%, P=0.042); and in GE, higher prevalence of stroke (17% vs. 6.7%, P=0.013). There was no difference between the groups regarding intraoperative variables. After multivariate analysis, age > 65-year-old was associated with greater morbidity, but it was not independent predictive factor for in-hospital mortality. Considering in-hospital mortality, stay in ward time length (P=0.006), cardiac (P=0.011) and respiratory complications (P=0.026) were independent predictive factors. CONCLUSION: This study suggests that patients > 65-year old were at increased risk of postoperative complications when submitted to isolated on-pump CABG in comparison to patients < 65-year-old, but not under increased risk of death.


OBJETIVO: Analisar os desfechos da cirurgia de revascularização do miocárdio (CRM) isolada com circulação extracorpórea em pacientes com idade > 65 anos em comparação àqueles com < 65 anos. MÉTODOS: foram analisados 253 pacientes submetidos consecutivamente à CRM isolada entre 1º de dezembro de 2010 a 31 de julho de 2012. Os pacientes foram separados em dois grupos: GI (idosos > 65 anos) e GA (adultos < 65 anos). Foram analisadas variáveis pré-operatórias, intraoperatórias (tempo de CEC, tempo de pinçamento aórtico, tempo de submissão à VM e número de enxertos) e pós-operatórias (morbidade, mortalidade e tempo de internação). RESULTADOS: Dos 253 pacientes, 103 pertenciam ao GI (40,7%) e 150 ao GA (59,3%). A taxa de morbidade foi significativamente maior no GI quando comparada ao GA (30% vs. 14%, P=0,004), porém não houve diferença na taxa de mortalidade (5,8% vs. 2,0%, P=0,165). No GA havia maior prevalência DM (39,6% vs. 27%, P=0,043) e tabagismo (32,2% vs. 19,8%, P=0,042); e no GI, maior prevalência de acidente vascular encefálico prévio (17% vs. 6,7%, P=0,013). Não houve diferença entre os grupos quanto às variáveis intraoperatórias. Na análise multivariada: tempo de internação na enfermaria (P=0,006), complicações cardíacas (P=0,011) e complicações respiratórias (P=0,026) foram variáveis preditoras de risco para maior mortalidade intra-hospitalar. No entanto, a idade > 65 anos não foi um fator preditor de risco associada a variável óbito. CONCLUSÃO: Este estudo sugere que pacientes com idade igual ou superior a 65 anos possuem um maior risco de complicações intra-hospitalares no pós-operatório de CRM isolada com CEC em comparação com pacientes mais jovens.

ABSTRACT

INTRODUCTION: Mechanical ventilation with positive end expiratory pressure (PEEP) improves oxygenation and treats acute pulmonary failure. However, increased intrathoracic pressure may cause regional blood flow alterations that may contribute to mesenteric ischemia and gastrointestinal failure. We investigated the effects of different PEEP levels on mesenteric leukocyte-endothelial interactions. METHODS: Forty-four male Wistar rats were initially anesthetized (Pentobarbital I.P. 50mg/kg) and randomly assigned to one of the following groups: 1) NAIVE (only anesthesia; n=9), 2) PEEP 0 (PEEP of 0 cmH2O, n=13), 3) PEEP 5 (PEEP of 5 cmH2O, n=12), and 4) PEEP 10 (PEEP of 10 cmH2O, n=13). Positive end expiratory pressure groups were tracheostomized and mechanically ventilated with a tidal volume of 10 mL/kg, respiratory rate of 70 rpm, and inspired oxygen fraction of 1. Animals were maintained under isoflurane anesthesia. After two hours, laparotomy was performed, and leukocyte-endothelial interactions were evaluated by intravital microscopy. RESULTS: No significant changes were observed in mean arterial blood pressure among groups during the study. Tracheal peak pressure was smaller in PEEP 5 compared with PEEP 0 and PEEP 10 groups (11, 15, and 16 cmH2O, respectively; p<0.05). After two hours of MV, there were no differences among NAIVE, PEEP 0 and PEEP 5 groups in the number of rollers (118±9,127±14 and 147±26 cells/10minutes, respectively), adherent leukocytes (3±1,3±1 and 4±2 cells/100µm venule length, respectively), and migrated leukocytes (2±1,2±1 and 2±1 cells/5,000µm², respectively) at the mesentery. However, the PEEP 10 group exhibited an increase in the number of rolling, adherent and migrated leukocytes (188±15 cells / 10 min, 8±1 cells / 100 µm and 12±1 cells / 5,000 µm², respectively; p<0.05). CONCLUSIONS: High intrathoracic pressure was harmful to mesenteric microcirculation in the experimental model of rats with normal lungs and ...

ABSTRACT

PURPOSE: Cecal ligation and puncture (CLP) has been used as a useful model for the induction of polymicrobial sepsis. Necrotic tissue resection and peritoneal lavage (REL) are the surgical procedures for controlling perforated appendicitis. The aim of this study was to evaluate leukocyte-endothelial interactions in the rat mesentery in vivo after CLP and REL. METHODS: Thirty-seven male Wistar rats (250-300 g) underwent laparotomy and were randomly assigned to the following groups: 1) SHAM; 2) CLP: animals submitted to CLP, 3) CLP+REL: animals submitted to CLP and REL. Mesenteric leukocyte-endothelial interactions were studied by intravital microscopy assessed once in each animal (3-5 postcapillary venules, 15-25 æm diameter) 24 hours after intervention. Follow-up was performed in all animals; this included analysis of glycemia, lactate, hematocrit, white blood cell count as well as a functional score that was the sum of scoring on the following parameters: alertness, mobility, piloerection, diarrhea, encrusted eyes, and dirty nose and tail. RESULTS: None of the animals showed significant changes in body weight (265 ± 20 g) or in hematocrit levels (46 percent ± 2 percent) during the experimental protocol. Compared to SHAM animals, CLP animals showed an increased number of rolling (2x), adherent, and migrating leukocytes (7x) in the mesenteric microcirculation, an increase in blood glucose (136 ± 8 mg/dL), lactate (3.58 ± 0.94 mmol/L), white cell count (23,570 ± 4,991 cells/mm³) and functional alterations (score 11 ± 1), characterized by impaired alertness and mobility, and presence of piloerection, diarrhea, encrusted eyes, and dirty nose and tail. The REL procedure normalized the number of rolling, adherent, and migrated leukocytes in the mesentery; glycemia; lactate; and white blood cell count. The REL procedure also improved the functional score (7 ± 1). CONCLUSION: Local and systemic inflammation was induced by CLP, while REL completely...


OBJETIVO: O procedimento de ligadura cecal e perfuração (CLP) tem sido usado como um modelo útil de indução de sepse polimicrobiana. A ressecção do tecido necrosado e lavagem peritoneal (REL) são procedimentos cirúrgicos freqüentemente utilizados para controlar uma apendicite perfurada. O objetivo desse estudo foi avaliar in vivo as interações leucócito-endotélio no mesentério de ratos após a CLP e REL. MÉTODOS: Trinta e sete ratos Wistar machos (250-300 g) foram submetidos à laparotomia e aleatoriamente divididos em grupos: 1) SHAM, 2) CLP: ratos submetidos à CLP, 3) CLP+REL: animais submetidos à CLP e REL. As interações leucócito-endotélio no mesentério foram estudadas através de microscopia intravital somente uma vez em cada animal (3-5 vênulas pós-capilares, 15-25 æm diâmetro), 24-horas após as intervenções. A evolução clínica foi realizada em todos os animais, incluindo glicemia, lactato, hematócrito, número total de células brancas e um escore funcional, o qual foi considerado como a somatória dos seguintes parâmetros: estado de alerta, mobilidade, piloereção, diarréia, olhos encrustados, e nariz e cauda sujos. RESULTADOS: Os animais não apresentaram alterações significantes no peso (265 ± 20 g) e hematócrito (46 ± 2 por cento) ao longo do estudo. Comparados ao SHAM, os animais CLP apresentaram aumento no número de leucócitos em rolamento (2x), aderidos (7x) e migrados (7x) na microcirculação mesentérica, aumentos da glicemia (136 ± 8 mg/dL), lactato (3,58 ± 0,94 mmol/L), leucocitose (23.570 ± 4.991 células/mm³) e alterações clínicas (escore 11±1), caracterizadas por comprometimento do estado de alerta e mobilidade, e presença de piloereção, diarréia, olhos encrustados, nariz e cauda sujos. REL normalizou o número de leucócitos em rolamento, aderidos e migrados no mesentério, a glicemia, o lactato e o número de leucócitos circulantes. REL também melhorou o escore clínico (7 ± 1). CONCLUSÃO: A CLP induziu inflamação local e sistêmica. A...
