Effects of Aerobic Training on Psychosocial Morbidity and Symptoms in Patients With Asthma A Randomized Clinical Trial

Background: Asthma symptoms reduce patients daily activities, impair their health-related quality of life (HRQoL), and increase their reports of anxiety and depress, all of which seem to be related to a decrease in asthma control. Aerobic exercise training is known to improve aerobic fitness and reduce dyspnea in asthmatics; however, its effect in reducing psychologic distress and symptoms remains poorly understood. We evaluated the role of an aerobic training program in improving HRQoL (primary aim) and reducing psychologic distress and asthma symptoms (secondary aims) for patients with moderate or severe persistent asthma. Methods: A total of 101 patients were randomly assigned to either a control group or an aerobic training group and studied during the period between medical consultations. Control group patients (educational program plus breathing exercises) (n = 51) and training group patients (educational program plus breathing exercises plus aerobic training) (n = 50) were followed twice a week during a 3-month period. HRQoL and levels of anxiety and depression were quantified before and after treatment. Asthma symptoms were evaluated monthly. Results: At 3 months, the domains (physical limitations, frequency of symptoms, and psychosocial) and total scores of HRQoL, significantly improved only in the training group patients (P < .001); the number of asthma-symptom-free days and anxiety and depression levels also significantly improved in this group (P < .001). In addition, a linear relationship between improvement in aerobic capacity and the days without asthma symptoms was observed (r = 0.47; P < .01). Conclusions: Our results suggest that aerobic training can play an important role in the clinical management of patients with persistent asthma. Further, they may be especially useful for patients with higher degrees of psychosocial distress.

Effects of Aerobic Training on Airway Inflammation in Asthmatic Patients

MENDES, F. A. R., F. M. ALMEIDA, A. CUKIER, R. STELMACH, W. JACOB-FILHO, M. A. MARTINS, and C. R. F. CARVALHO. Effects of Aerobic Training on Airway Inflammation in Asthmatic Patients. Med. Sci. Sports Exerc., Vol. 43, No. 2, pp. 197-203, 2011. Purpose: There is evidence suggesting that physical activity has anti-inflammatory effects in many chronic diseases; however, the role of exercise in airway inflammation in asthma is poorly understood. We aimed to evaluate the effects of an aerobic training program on eosinophil inflammation (primary aim) and nitric oxide (secondary aim) in patients with moderate or severe persistent asthma. Methods: Sixty-eight patients randomly assigned to either control (CG) or aerobic training (TG) groups were studied during the period between medical consultations. Patients in the CG (educational program + breathing exercises; N = 34) and TG (educational program + breathing exercises + aerobic training; N = 34) were examined twice a week during a 3-month period. Before and after the intervention, patients underwent induced sputum, fractional exhaled nitric oxide (FeNO), pulmonary function, and cardiopulmonary exercise testing. Asthma symptom-free days were quantified monthly, and asthma exacerbation was monitored during 3 months of intervention. Results: At 3 months, decreases in the total and eosinophil cell counts in induced sputum (P = 0.004) and in the levels of FeNO (P = 0.009) were observed after intervention only in the TG. The number of asthma symptom-free days and (V) over dotO(2max) also significantly improved (P < 0.001), and lower asthma exacerbation occurred in the TG (P < 0.01). In addition, the TG presented a strong positive relationship between baseline FeNO and eosinophil counts as well as their improvement after training (r = 0.77 and r = 0.9, respectively). Conclusions: Aerobic training reduces sputum eosinophil and FeNO in patients with moderate or severe asthma, and these benefits were more significant in subjects with higher levels of inflammation. These results suggest that aerobic training might be useful as an adjuvant therapy in asthmatic patients under optimized medical treatment.

Oral Hygiene Indirect Instruction and Periodic Reinforcements: Effects on Index Plaque in Schoolchildren

The aim of this study was to evaluate the effectiveness of the indirect instruction and the influence of the periodic reinforcement on the plaque index in schoolchildren. Forty schoolchildren aged from 7 to 9 years old were selected from a public school. After determining the initial O`Leary Plaque Index all schoolchildren were submitted to a program for oral hygiene through indirect instruction - ""The Smiling Robot"". The schoolchildren were divided into 2 groups: with and without motivation reinforcement. The index plaque exam was performed in both groups after 30, 60 and 90 days of the educational program. Comparing the groups, the plaque index decreasing could be observed in the group with reinforcement with statistically significant difference. For the group with reinforcement, statistically significant difference among the evaluations was found. For the group without reinforcement, significant decrease in the plaque index was found after 30 days when compared to the first, third and fourth evaluations. The indirect instruction with ""The Smiling Robot ""promoted a positive initial impact on the decrease of plaque index in the schoolchildren. The periodic reinforcements showed snore suitable results and significant reduction of the plaque index in the course of the evaluations.

Sistema ??nico de Sa??de: a busca do entendimento de seus princ??pios e sistemas de valores para profissionais do servi??o p??blico

No per??odo de 2004 a 2008, o Minist??rio da Sa??de, conveniado com institui????es de ensino superior, ofereceu aos servidores dos n??cleos estaduais da sa??de um curso de especializa????o sobre Planejamento Estrat??gico e Pol??ticas P??blicas com o objetivo de informar, esclarecer e discutir o Sistema ??nico de Sa??de (SUS). A pesquisa discute esse programa educacional enquanto estrat??gia de mudan??a de cultura organizacional no Sistema ??nico de Sa??de. Dois dos principais focos do programa educacional foram a compreens??o dos pressupostos filos??ficos do SUS pelos funcion??rios do Minist??rio da Sa??de e a transforma????o do conhecimento t??cito dos servidores em conhecimento sistematizado via elabora????o de monografias, na perspectiva da incorpora????o de uma nova vis??o sobre o SUS. Foi utilizada abordagem metodol??gica quali-quantitativa, com uso de question??rios, entrevistas e grupos focais com os 636 respondentes que participaram do curso. A an??lise dos resultados considerou a avalia????o que os servidores/alunos faziam do curso, suas expectativas, suas necessidades de reconhecimento do trabalho e de satisfa????o pessoal, e a monografia realizada. Os resultados indicam a ocorr??ncia de aprendizagem e sensibiliza????o para as mudan??as; no entanto, no n??vel individual fatores organizacionais como a participa????o, comunica????o, reconhecimento de compet??ncias e pr??ticas de Recursos Humanos foram mencionados como entraves para o aprendizado e modifica????o da cultura organizacional. Conclui-se que os processos de aprendizagem desenvolvidos pela organiza????o devem ser processos continuados e n??o estrat??gias de a????o pontuais.

Efeitos de um programa de educação para a saúde no doente portador de DPOC

Objectivo: Verificar o efeito de um programa de educação para a saúde em doentes portadores de DPOC. Metodologia: Estudo experimental (ensaio clínico) com 18 doentes portadores de DPOC seleccionados aleatoriamente através da consulta de Medicina Geral e Familiar. Depois de informar os objectivos do estudo e os aspectos éticos, os participantes realizaram uma avaliação da função pulmonar, capacidade de tolerância ao exercício, qualidade de vida, actividades de vida diária (AVD), dispneia e ansiedade e depressão. Posteriormente os indivíduos do grupo controlo receberam um manual informativo e os incluídos no grupo experimental além de receber o manual foram submetidos a 6 sessões de educação. Após 8 semanas todos os doentes foram reavaliados. O nível de significância utilizado nos testes estatísticos foi α=0.05 (intervalo de confiança de 95%). Resultados: A análise da diferença dos ganhos entre os grupos revelou-se estatisticamente significativa nas variáveis qualidade de vida (p<0,001), AVD (p<0,001) e depressão (p<0,001). Na capacidade de tolerância ao exercício ambos os grupos melhoraram significativamente mas a diferença de ganhos não foi estatisticamente significativa (p=0,289), tal como na variável ansiedade (p=0,960). Conclusão: Este estudo parece demonstrar que o programa de educação foi eficaz nas variáveis qualidade de vida, AVD e depressão.

Eco-epidemiological aspects of Trypanosoma cruzi, Trypanosoma rangeli and their vector (Rhodnius pallescens) in Panama

The eco-epidemiology of T. cruzi infection was investigated in the Eastern border of the Panama Canal in Central Panama. Between 1999 and 2000, 1110 triatomines were collected: 1050 triatomines (94.6%) from palm trees, 27 (2.4%) from periurban habitats and 33 (3.0%) inside houses. All specimens were identified as R. pallescens. There was no evidence of vector domiciliation. Salivary glands from 380 R. pallescens revealed a trypanosome natural infection rate of 7.6%, while rectal ampoule content from 373 triatomines was 45%. Isoenzyme profiles on isolated trypanosomes demonstrated that 85.4% (n = 88) were T. cruzi and 14.6% (n = 15) were T. rangeli. Blood meal analysis from 829 R. pallescens demonstrated a zoophilic vector behavior, with opossums as the preferential blood source. Seroprevalence in human samples from both study sites was less than 2%. Our results demonstrate that T. cruzi survives in the area in balanced association with R. pallescens, and with several different species of mammals in their natural niches. However, the area is an imminent risk of infection for its population, consequently it is important to implement a community educational program regarding disease knowledge and control measures.

Successful prevention of the transmission of vancomycin-resistant enterococci in a Brazilian public teaching hospital

INTRODUCTION: Vancomycin-resistant enterococci (VRE) can colonize or cause infections in high-risk patients and contaminate the environment. Our objective was to describe theepidemiological investigation of an outbreak of VRE, the interventions made, and their impact on its control. METHODS: We conducted a retrospective, descriptive, non-comparative study by reviewing the charts of patients with a VRE-positive culture in the University Hospital of Campinas State University, comprising 380 beds, 40 of which were in intensive care units (ICUs), who were admitted from February 2008-January 2009. Interventions were divided into educational activity, reviewing the workflow processes, engineering measures, and administrative procedures. RESULTS: There were 150 patients, 139 (92.7%) colonized and 11 (7.3%) infected. Seventy-three percent were cared for in non-ICUs (p = 0.028). Infection was more frequent in patients with a central-line (p = 0.043), mechanical ventilation (p = 0.013), urinary catheter (p = 0.049), or surgical drain (p = 0.049). Vancomycin, metronidazole, ciprofloxacin, and third-generation cephalosporin were previously used by 47 (31.3%), 31 (20.7%), 24 (16%), and 24 (16%) patients, respectively. Death was more frequent in infected (73%) than in colonized (17%) patients (p < 0.001). After the interventions, the attack rate fell from 1.49 to 0.33 (p < 0.001). CONCLUSIONS: Classical risk factors for VRE colonization or infection, e.g., being cared for in an ICU and previous use of vancomycin, were not found in this study. The conjunction of an educational program, strict adhesion to contact precautions, and reinforcement of environmental cleaning were able to prevent the dissemination of VRE.

Efetividade de um programa de educação baseado na neurofisiologia da dor e exercício aquático em comparação com um programa de exercício aquático isolado em indivíduos com dor lombar crónica

RESUMO: Introdução e Objetivos: O exercício é uma das modalidades mais utilizadas no tratamento da Dor Lombar Crónica (DLC) mas também a mais recomendada pela literatura atual. Apesar de efetivo, o exercício não parece responder às características cognitivas e comportamentais identificadas nesta população. Assim, existem recomendações para que seja coadjuvado por educação de forma a minimizar a influência nos resultados de variáveis como o medo do movimento. Porém não é conhecido o real impacto nos resultados de um programa educacional quando acrescentado a um programa de exercício. O objetivo deste estudo foi investigar os efeitos de um programa de exercício aquático coadjuvado por educação baseada na neurofisiologia da dor (grupo experimental) comparado a um programa de exercício aquático isolado (grupo controlo), ao nível da intensidade da dor, incapacidade funcional e medo do movimento, em indivíduos com DLC. Metodologia: Sessenta e dois indivíduos com DLC foram aleatoriamente distribuídos pelo grupo experimental (n= 30) e pelo grupo controlo (n= 32). Os participantes de ambos os grupos realizaram um programa de 6 semanas constituído por 12 sessões de exercício aquático. No caso do grupo experimental foram realizadas duas sessões de educação baseada na neurofisiologia da dor (EBN) antes do programa de exercício aquático. As medidas de avaliação primárias foram a intensidade da dor (Escala Visual Análoga) e a incapacidade funcional (Quebec Back Pain Disability Scale). Secundariamente avaliou-se o medo do movimento através da Tampa Scale of Kinesiophobia. Os participantes foram avaliados antes da intervenção, 3 semanas após o início do programa de exercício aquático, no final da intervenção e 3 meses após o final da intervenção. Resultados: Foram encontradas melhorias significativas no final da intervenção ao nível da intensidade da dor e incapacidade funcional em ambos os grupos. Após 3 meses, apenas o grupo experimental apresentou melhorias significativas nas variáveis primárias. Na comparação entre grupos, os resultados foram favoráveis ao grupo experimental para a intensidade da dor nas avaliações após a intervenção (p= 0,032) e após 3 meses (p= 0,007). Quanto à incapacidade funcional e medo do movimento não se verificaram diferenças significativas entre grupos em nenhum momento. Também as medidas de relevância clínica utilizadas (tamanho do efeito; risco relativo; number needed to treat) favoreceram o grupo experimental. Conclusões: Os resultados mostram que um programa de exercício aquático e EBN foi mais efetivo na melhoria da intensidade da dor a curto e médio prazo do que um programa de exercício aquático isolado. Apesar de serem necessárias mais investigações sobre este tema, este estudo demonstra que a EBN pode otimizar os resultados quando associada a outras intervenções ativas como o exercício aquático.----------------ABSTRACT: Introduction and Objectives: Exercise is one of the most used modalities in the treatment of Chronic Low Back Pain (CLBP) but also the most recommended in current literature. Although it’s effective, exercise does not seem to respond to the cognitive and behavioural characteristics identified in this population. Thus, it is recommended to be assisted by education in order to minimize the influence of variables on the results such as the fear of movement. However, the real impact on the results of an educational program when added to an exercise program is not known. The aim of this study was to investigate the effects of a program of aquatic exercise and neurophysiology pain education (experimental group) compared to aquatic exercise program alone (control group), on the outcomes of pain intensity, functional disability and fear of movement in individuals with CLBP. Methodology: Sixty two individuals with CLBP were randomly distributed in the experimental group (n = 30) and in the control group (n = 32). Participants in both groups performed a 6-week program consisting of 12 sessions of aquatic exercise. In the case of the experimental group two sessions of neurophysiology pain education (NPE) were performed before the aquatic exercise program. The primary outcomes were pain intensity (Visual Analogue Scale) and functional disability (Quebec Back Pain Disability Scale). Secondarily, the fear of movement through the Tampa Scale of Kinesiophobia was assessed. Participants were assessed before the intervention, three weeks after the start of the aquatic exercise program, at the end of the intervention and 3 months after the end of the intervention. Results: Significant improvements were found at the end of the intervention in both groups in what intensity of pain and functional disability were concerned. After 3 months, only the experimental group showed significant improvements in the primary outcomes. Comparing both groups, the results favoured to the experimental group for intensity of pain scores after the intervention (p = 0.032) and after 3 months (p = 0.007). The functional disability and fear of movement had no significant differences between groups at any time. In addition, the measures of clinical relevance used (size effect; relative risk; number needed to treat) favoured the experimental group. Conclusions: The results show that a program of aquatic exercise and NPE were more effective in improving pain intensity at a short and medium term than an aquatic exercise program alone. Although more research on this topic is needed, this study demonstrates that the NPE can optimize results when combined with other active interventions such as aquatic exercise.

Education to a Healthy Lifestyle Improves Symptoms and Cardiovascular Risk Factors – AsuRiesgo Study

Background: Cardiovascular diseases are the current leading causes of death and disability globally. Objective: To assess the effects of a basic educational program for cardiovascular prevention in an unselected outpatient population. Methods: All participants received an educational program to change to a healthy lifestyle. Assessments were conducted at study enrollment and during follow-up. Symptoms, habits, ATP III parameters for metabolic syndrome, and American Heart Association’s 2020 parameters of cardiovascular health were assessed. Results: A total of 15,073 participants aged ≥ 18 years entered the study. Data analysis was conducted in 3,009 patients who completed a second assessment. An improvement in weight (from 76.6 ± 15.3 to 76.4 ± 15.3 kg, p = 0.002), dyspnea on exertion NYHA grade II (from 23.4% to 21.0%) and grade III (from 15.8% to 14.0%) and a decrease in the proportion of current active smokers (from 3.6% to 2.9%, p = 0.002) could be documented. The proportion of patients with levels of triglycerides > 150 mg/dL (from 46.3% to 42.4%, p < 0.001) and LDL cholesterol > 100 mg/dL (from 69.3% to 65.5%, p < 0.001) improved. A ≥ 20% improvement of AHA 2020 metrics at the level graded as poor was found for smoking (-21.1%), diet (-29.8%), and cholesterol level (-23.6%). A large dropout as a surrogate indicator for low patient adherence was documented throughout the first 5 visits, 80% between the first and second assessments, 55.6% between the second and third assessments, 43.6% between the third and fourth assessments, and 38% between the fourth and fifth assessments. Conclusion: A simple, basic educational program may improve symptoms and modifiable cardiovascular risk factors, but shows low patient adherence.

Evolution of endurance during a multidisciplinary treatment of chronic low back pain and its influence of work capacity

Introduction: Low back pain is a common disorder touching up to 80% of the population, with redundancies of up to 70%. A small proportion would go on to develop chronic low back pain (LBP) with reduced work capacity and they would count for the majority of the costs. Up to day, a multi-disciplinary treatment program is one of the best approaches. In the program one of the mile-stones is restoration of function. The aim of this study was to follow patients, according to the endurance change after the program and its influence on workability during one year after inclusion in a such program. Method: Patients were following a multidisciplinary treatment for 3 weeks including physiotherapy, occupation measures combined with an educational program with behavioural and psychological interventions on an outpatient program. We studied the endurance with the help of the Bruce test, accomplished at the beginning and at the end of the program. On the other hand the patients filled out pain questionnaires and PACT score according their own impression on workability. Results: There were a clear relation between the increase in the cardiovascular endurance and the increased workability. Almost every patient presented an increase in the VO2 max, even though the workability did not follow. This increase were associated with a decrease in pain apprehension. Conclusion: A multidisciplinary treatment program, teaching the patients how to care with their pain and to accept it even if it persist is successful in lowering the global pain. If the program allows the patients to strengthen the endurance, the workability will increase in parallel. In this way the patients were able to reduce the consummation of medicaments and to increase the work capacity.

How to improve the formal analytic reasoning and scientific motivation in the intellectual training of medical students

A review article of the The New England Journal of Medicine refers that almost a century ago, Abraham Flexner, a research scholar at the Carnegie Foundation for the Advancement of Teaching, undertook an assessment of medical education in 155 medical schools in operation in the United States and Canada. Flexner’s report emphasized the nonscientific approach of American medical schools to preparation for the profession, which contrasted with the university-based system of medical education in Germany. At the core of Flexner’s view was the notion that formal analytic reasoning, the kind of thinking integral to the natural sciences, should hold pride of place in the intellectual training of physicians. This idea was pioneered at Harvard University, the University of Michigan, and the University of Pennsylvania in the 1880s, but was most fully expressed in the educational program at Johns Hopkins University, which Flexner regarded as the ideal for medical education.
