Cardiovascular prevention in HIV patients: Results from a successful intervention program

Objectives: To analyze the effect of a prevention program oil the estimated cardiovascular risk calculated by three risk scores. Methods: We prospectively evaluated 87 HIV+ patients with elevated cardiovascular risk estimation. Framirigham (FIRS), PROCAM and National Cholesterol Education Program (ATP-III) were applied. Cardiovascular risk was defined as elevated if >10%. All patients received non-pharmacological (diet, exercise, smoking cessation) and, when appropriate, pharmacological therapy. Results: Mean age was 52 years, 92% were male, 39.1% were smokers, 70.1% had hypertension, 18.4% had diabetes. All patients were under HAART, 56.3% were receiving protease inhibitors (131). After 6 months, intervention was associated to significant changes oil triglycerides (298 242 and 206 +/- 135 mg/dL, p<0.05), total-cholesterol (224 +/- 47 and 189 +/- 38 mg/dL, p<0.001). LDL-cholesterol (129 +/- 44 and 109 +/- 30 mg/dL,p<0.001). Frequencies of patients with elevated cardiac risk before and 6 months after intervention were 92% x 27.6% (p < 0.0001), 80.5% x 50.6% (p < 0.0002), and 25.3% x 14.9% (p = 0.12), for FIRS, ATP III and PROCAM, respectively. Conclusions: An intervention Program focused on reduction of traditional risk factors was able to decrease the frequency of patients with HIV infection and elevated cardiovascular risk estimation. FIRS showed greater sensitivity than the other scores. (C) 2008 Elsevier Ireland Ltd. All rights reserved.

Postural Control in Elderly Persons with Osteoporosis: Efficacy of an Intervention Program to Improve Balance and Muscle Strength A Randomized Controlled Trial

Burke TN, Franc, a FJR, de Meneses SRF, Cardoso VI, Marques AP: Postural control in elderly persons with osteoporosis: Efficacy of an intervention program to improve balance and muscle strength: A randomized controlled trial. Am J Phys Med Rehabil 2010; 89: 549-556. Objective: To assess the efficacy of an exercise program aiming to improve balance and muscular strength, for postural control and muscular strength of women with osteoporosis. Design: Sample consisted of 33 women with osteoporosis, randomized into one of two groups: intervention group, in which exercises for balance and improvement of muscular strength of the inferior members were performed for 8 wks (n = 17, age 72.8 +/- 3.6 yrs); control group, which was women not practicing exercises (n = 16, age 74.4 +/- 3.7 yrs). At baseline and after 8 wks of treatment, postural control was assessed using a force plate (Balance Master, Neurocom), and muscular strength during ankle dorsiflexion, knee extension, and flexion was assessed by dynamometry. Results: Adherence to the program was 82%. When compared with the control group, individuals in the intervention group significantly improved the center of pressure velocity (P = 0.02) in the modified clinical test of sensory interaction for balance test, center of pressure velocity (P < 0.01), and directional control (P < 0.01) in limits of stability test, isometric force during ankle dorsiflexion (P = 0.01), knee extension (P < 0.01), and knee flexion (P < 0.01). Conclusions: Balance and strength exercises are effective in improving postural control and lower-limb strength in elderly women with osteoporosis.

Predictive factors of non-deterioration of glucose tolerance following a 2-year behavioral intervention

Aim: To identify predictive factors associated with non-deterioration of glucose metabolism following a 2-year behavioral intervention in Japanese-Brazilians. Methods: 295 adults (59.7% women) without diabetes completed 2-year intervention program. Characteristics of those who maintained/improved glucose tolerance status (non-progressors) were compared with those who worsened (progressors) after the intervention. In logistic regression analysis, the condition of non-progressor was used as dependent variable. Results: Baseline characteristics of non-progressors (71.7%) and progressors were similar, except for the former being younger and having higher frequency of disturbed glucose tolerance and lower C-reactive protein (CRP). In logistic regression, non-deterioration of glucose metabolism was associated with disturbed glucose tolerance impaired fasting glucose or impaired glucose tolerance - (p < 0.001) and CRP levels <= 0.04 mg/dL (p = 0.01), adjusted for age and anthropometric variables. Changes in anthropometry and physical activity and achievement of weight and dietary goals after intervention were similar in subsets that worsened or not the glucose tolerance status. Conclusion: The whole sample presented a homogeneous behavior during the intervention. Lower CRP levels and diagnosis of glucose intolerance at baseline were predictors of non-deterioration of the glucose metabolism after a relatively simple intervention, independent of body adiposity.

Reflexão sobre a imigração japonesa no Brasil sob o ângulo da adiposidade corporal

Populações migrantes representam oportunidade para se investigar a contribuição de fatores ambientais na gênese da obesidade e suas comorbidades. Em 1993, o Japanese-Brazilian Diabetes Study Group estudou a prevalência de diabetes e doenças associadas em nipo-brasileiros residentes em Bauru, SP. Utilizando critérios específicos para asiáticos, 22,4% dos nipo-brasileiros foram caracterizados como portadores de excesso de peso nessa primeira fase do estudo. Na segunda fase, em 2000, essa prevalência subiu para 44,2%, e 50,3% apresentavam obesidade central. Essa população também apresentava alta prevalência de diabetes tipo 2, hipertensão e dislipidemia, componentes da síndrome metabólica. O JBDS Group também mostrou a associação entre hábitos ocidentais, especialmente alimentação rica em gordura saturada, e a ocorrência de síndrome metabólica. Em 2005, motivado por esses achados, o JBDS Group iniciou a terceira fase do estudo que constou de programa de intervenção com base em orientação para dieta saudável e prática de atividade física, utilizando recursos factíveis em termos de saúde pública no Brasil. Após um ano de intervenção, o JBDS Group observou diminuição nos parâmetros antropométricos, pressão arterial e níveis de glicemia e colesterol. Tempo de acompanhamento maior é necessário para avaliar a persistência desses benefícios e o impacto deles no risco de desenvolver diabetes e eventos cardiovasculares.

Participação comunitária em um programa de intervenção em área de proteção ambiental

Este artigo discute os conceitos de participação e empowerment em Promoção da Saúde e Desenvolvimento Sustentável, considerando as agendas de implementação local, Municípios/Cidades Saudáveis e Agenda 21, e a importância dos processos de avaliação nesse contexto, por meio da análise de uma intervenção em área de mananciais - o Programa Bairro Ecológico (PBE), desenvolvido em 51 bairros do município de São Bernardo do Campo, Estado de São Paulo, Brasil. O estudo teve por objetivo avaliar os processos de participação e empowerment da comunidade, a partir das ações desencadeadas pelo PBE. Foram aplicados questionários e realizados grupos focais com moradores de bairros que sofreram a intervenção. Também foram realizadas entrevistas individuais com gestores do programa e do poder judiciário. Os resultados indicaram que a participação na implementação do PBE favoreceu o empowerment individual e grupal, presente nas duas comunidades estudadas. As comunidades tornaram-se mais organizadas. Há indícios de que os processos de tomada de decisões são centralizados. Apesar disso, as comunidades entendem que sua participação no programa lhes traz muitas coisas boas. Houve um processo participativo no desenvolvimento do programa, ainda que alguns relatos apontem para o caráter obrigatório da participação. Deve-se destacar o impacto do envolvimento e fortalecimento das lideranças na implementação e sustentabilidade do programa. No que diz respeito a esta última, verificou-se que a sensibilização ambiental tem sido fator determinante para a execução e manutenção das ações ao longo do tempo.

Efetividade de programa de agentes comunitários na promoção da saúde bucal

OBJETIVO:Avaliar mudanças em conhecimentos, atitudes e acesso/utilização de serviços odontológicos decorrentes de um programa de promoção da saúde bucal com agentes comunitários de saúde. MÉTODOS:Um projeto de capacitação combinando ensino-aprendizagem, apoio e supervisão, foi desenvolvido entre os meses de julho de 2003 a agosto de 2004. As mudanças foram avaliadas por meio de entrevistas estruturadas em que participaram 36 agentes comunitários de saúde e uma amostra de 91 mulheres e mães, representativa de donas de casa com 25 a 39 anos de idade, alfabetizadas e residentes em domicílios de três a seis cômodos no município de Rio Grande da Serra (SP). Foram colhidos dados sobre conhecimentos de saúde-doença bucal, práticas e capacidades auto-referidas em relação ao auto-exame, higiene bucal, número de residentes e de escovas dentais individuais e coletivas em cada domicílio e acesso e uso de serviços odontológicos. Por meio do teste t de Student pareado, foram comparadas as médias dos valores obtidos antes e depois do programa para cada um dos grupos estudados. As respostas foram analisadas adotando-se um nível de significância de 5%. RESULTADOS: Foram observadas diferenças estatisticamente significativas para questões relativas ao conhecimento de saúde bucal entre os agentes e entre as mulheres antes e depois da capacitação (p<0,05). Desequilíbrio entre o número de escovas e de indivíduos em cada família diminuiu. A freqüência da escovação e do uso do fio dental se elevou depois da atuação dos agentes. Os valores de auto-avaliação da higiene bucal aumentaram. Modificação nas práticas e capacidades auto-referidas mostrou significativa elevação da auto-confiança. O acesso ao serviço foi mais fácil (p<0,000) e seu uso mais regular (p<0,000) entre mulheres. CONCLUSÕES: Houve mudanças positivas na percepção em relação a aspectos de saúde bucal, na auto-confiança e no acesso e uso de serviços odontológicos. Tais mudanças po

Relationship among eccentric hip and knee torques, symptom severity and functional capacity in females with patellofemoral pain syndrome

Objective: To determine the relationships between eccentric hip and knee torques, symptom severity and functional capacity in females with patellofemoral pain syndrome (PFPS). Design: Within-subject correlational study. Setting: University biomechanics laboratory. Participants: 10 females diagnosed with PFPS. Main outcome measures: Eccentric strength of the hip abductors and lateral rotators, and knee extensors were assessed using an isokinetic dynamometer. A 10-cm visual analog scale was used to determine usual knee pain in the last week. The Anterior Knee Pain Scale (AKPS) was used to determine the functional capacity of the patients. Results: The study found that the greater the eccentric knee extensor and hip lateral rotator torques, the higher the functional capacity of the patients (p = 0.02, r = 0.72; p = 0.02, r = 0.72). It was also shown that the greater hip lateral rotator torque, the less the usual pain reported in the last week (p = 0.004, r = -0.84). Despite the lack of statistical significance (p = 0.11), it was also found a modest negative relationship between the eccentric knee extensor torque and the usual pain reported in the last week (r = -0.56) that was considered clinically meaningful (d = 1.4). Conclusions: This study showed that eccentric knee extensor and hip lateral rotator torques were associated with functional capacity and pain level in females with PFPS. Further investigations should be carried out to verify the effects of an intervention program focused on the eccentric action of these muscles with respect to the symptoms in patients with PFPS.

Dietary omega-3 fatty acid and omega-3: omega-6 fatty acid ratio predict improvement in glucose disturbances in Japanese Brazilians

Objective: We investigated whether lifestyle-induced changes in dietary fat quality are related to Improvements on glucose metabolism disturbances in Japanese Brazilians at high risk of type 2 diabetes Methods: One hundred forty-eight first- and second-generation subjects with impaired glucose tolerance or impaired fasting glycemia who attended a lifestyle intervention program for 12 mo were studied in the city of Bauru. State of Sao Paulo, Brazil Dietary fatty acid intakes at baseline and after 12 mo were estimated using three 24-h recalls. The effect of dietary fat intake on glucose metabolism was investigated by multiple logistic regression models Results: At baseline, mean standard deviation age and body mass index were 60 II y and 25 5 4.2 kg/m2, respectively After 12 mo. 92 subjects had normal plasma glucose levels and 56 remained in prediabetic conditions. Using logistic regression models adjusted for age, gender, generation, basal intake of explanatory nutrient, energy intake, physical activity, and waist circumference, the odds ratios (95% confidence intervals) for reversion to normoglycemia were 3 14 (1 22-8 10) in the second wrote of total w-3 fatty acid, 4 26 (1.34-13 57) in the second tunic of eicosapentaenoic acid, and 280 (1 10-7.10) in the second tertile of linolenic acid. Similarly. subjects in the highest wrote of w-3.w-6 fatty acid ratio showed a higher chance of improving glucose disturbances (2 51, 1.01-6.37) Conclusions: Our findings support the evidence of an independent protective effect of omega-3 fatty acid and of a higher omega-3:omega-6 fatty acid ratio on the glucose metabolism of high-risk individuals (C) 2010 Elsevier Inc All rights reserved.

Oral Health Promotion Through an Online Training Program for Medical Students

The objective of this study was to compare the impact on knowledge and counseling skills of face-to-face and Internet-based oral health training programs on medical students. Participants consisted of 148 (82 percent) of the 180 invited students attending their fifth academic year at the Faculty of Medicine, University of Sao Paulo, Brasil, in 2007. The interventions took place during a three-month training period in the clinical Center for Health Promotion, which comprised part of a clerkship in Internal Medicine. The students were divided into four groups: 1) Control Group (Control), with basic intervention; 2) Brochure Group (Br), with basic intervention plus complete brochure with oral health themes; 3) Cybertutor Group (Cy), with basic intervention plus access to an Internet-based training program about oral health themes; and 4) Cybertutor + Contact Group (Cy+C), the same as Cy plus brief proactive contact with a tutor. The impact of these interventions on student knowledge was measured with pre- and post assessments, and student skills in asking and counseling about oral health were assessed with an objective structured clinical examination (OSCE). Multivariate logistic regression models were applied to identify the odds ratios of scoring above Control's medians on the final assessment and the OSCE. In the results, Cy+C performed significantly better than Control on both the final assessment (OR 9.4; 95% CI 2.7-32.8) and the OSCE (OR 5.6; 95% CI 1.9-16.3) and outperformed all the other groups. The Cy+C group showed the most significant increase in knowledge and the best skills in asking and counseling about oral health.

Effect of a 36-month pharmaceutical care program on pharmacotherapy adherence in elderly diabetic and hypertensive patients

Objective: The primary objective of this study was to evaluate the effect of a pharmaceutical care program on pharmacotherapy adherence in elderly diabetic and hypertensive patients. The clinical outcomes of this pharmacotherapy adherence approach were the secondary objective of the study. Setting: Public Primary Health Care Unit in a municipality in the Brazilian State of Sao Paulo. Method: A 36-month randomized, controlled, prospective clinical trial was carried out with 200 patients divided into two groups: control (n = 100) and intervention (n = 100). The control group received the usual care offered by the Primary Health Care Unit (medical and nurse consultancies). The patients randomized into the intervention group received pharmaceutical care intervention besides the usual care offered. Main outcome measure: Pharmacotherapy adherence (Morisky-Green test translated into Portuguese and computerized dispensed medication history) and clinical measurements (blood pressure, fasting glucose, A1C hemoglobin, triglycerides and total cholesterol) were evaluated at the baseline and up to 36 months. A P value < 0.05 was considered statistically significant. Results: A total of 97 patients from the intervention group and 97 patients from the control group completed the study (n = 194). Significant improvements in the pharmacotherapy adherence were verified for the intervention group according to the Morisky-Green test (50.5% of adherent patients at baseline vs. 83.5% of adherent patients after 36 months; P < 0.001) and the computerized dispensed medication history (52.6% of adherent patients at baseline vs. 83.5% of adherent patients after 36 months; P < 0.001); no significant changes were verified in the control group. Significant improvements in the number of patients reaching adequate values for their blood pressure (26.8% at baseline vs. 86.6% after 36-months; P < 0.001), fasting glucose (29.9% at baseline vs. 70.1% after 36 months; P < 0.001), A1C hemoglobin (3.3% at baseline vs. 63.3% after 36 months; P < 0.001), triglycerides (47.4% at baseline vs. 74.2% after 36 months; P < 0.001) and total cholesterol (59.8% at baseline vs. 80.4% after 36 months; P = 0.002) were verified in the intervention group, but remained unchanged in the control group. Conclusion: These results indicated the effectiveness of pharmaceutical care in improving pharmacotherapy adherence, with positive effects in the clinical outcomes of the patients studied.

Effect of aquatic respiratory exercise-based program in patients with fibromyalgia

Objective: This study assessed the effects of an aquatic respiratory exercise-based program in patients with fibromyalgia (FMS). Methods: Forty women, aged between 20 and 60 years, were randomly assigned into two groups of 20 patients: the aquatic respiratory exercise-based program (ARG) and the control group (CTL). The ARG group performed the exercise program for 1 h, four times a week, for 4 weeks which included: (i) warming-Lip; (ii) respiratory exercises, consisting of five different breathing patterns, along With upper, lower limbs and trunk movements (45 min); and (iii) relaxation exercises. Both groups were included in supervised recreational activities of 1 h, once a week, for 4 weeks. Questionnaires were applied before and after intervention to assess quality of life and functional capacity (SF-36, Fibromyalgia Impact Questionnaire [FIQ]), anxiety (Hamilton Anxiety Scale [HAS]), and quality of sleep (Pittsburg Sleep Quality Index [PSQI]). Number of tender points and pain (Visual Analogue Scale [VAS]) were also evaluated. Results: At baseline there was no difference between the two groups, including number of tender points and questionnaire responses. After intervention, the ARG group, compared with the CTL group, showed improvement in SF-36 scores (physical functioning P = 0.001, bodily pain 1) = 0.001, vitality P = 0.009, social functioning P = 0.001, emotional role P = 0.001), in FIQ (total score P = 0.049, work missed P = 0.036, fatigue P = 0.013, morning tiredness P = 0.007) plus in VAS-pain (P = 0.029), VAS-dyspnea (P = 0.04), anxiety (HAS P = 0.005) and quality of sleep (PSQI P = 0.004). Conclusions: The short-term aquatic respiratory exercise-based program improved pain, quality of life, functional capacity, anxiety and quality of sleep in patients with FMS and may be a relevant addition to the treatment of these patients.

Detection of nosocomial malnutrition is improved in Amazon region by a standard clinical nutrition education program

Background: In Brazil hospital malnutrition is highly prevalent. physician awareness of malnutrition is low, and nutrition therapy is underprescribed. One alternative to approach this problem is to educate health care providers in clinical nutrition. The present study aims to evaluate the effect of an intensive education course given to health care professionals and students on the diagnosis ability concerning to hospital malnutrition. Materials and methods: An intervention study based on a clinical nutrition educational program, offered to medical and nursing students and professionals, was held in a hospital of the Amazon region. Participants were evaluated through improvement of diagnostic ability, according to agreement of malnutrition diagnosis using Subjective Global Assessment before and after the workshop, as compared to independent evaluations (Kappa Index, k). To evaluate the impact of the educational intervention on the hospital malnutrition diagnosis, medical records were reviewed for documentation of parameters associated with nutritional status of in-patients. The SPSS statistical software package was used for data analysis. Results: A total of 165 participants concluded the program. The majority (76.4%) were medical and nursing students. Malnutrition diagnosis improved after the course (before k = 0.5; after k = 0.64; p < 0.05). A reduction of false negatives from 50% to 33.3% was observed. During the course, concern of nutritional diagnosis was increased W = 17.57; p < 0.001) and even after the course, improvement on the height measurement was detected chi(2) 12.87;p < 0.001). Conclusions: Clinical nutrition education improved the ability of diagnosing malnutrition; however the primary impact was on medical and nursing students. To sustain diagnostic capacity a clinical nutrition program should be part of health professional curricula and be coupled with continuing education for health care providers.

Long-term follow-up of children with extrahepatic portal vein obstruction: impact of an endoscopic sclerotherapy program on bleeding episodes, hepatic function, hypersplenism, and mortality

Background: Endoscopic sclerotherapy (ES) has been the standard treatment for children with idiopathic extrahepatic portal vein obstruction (EHPVO). Portosystemic shunts are indicated when variceal bleeding cannot be controlled by ES. Recently, mesenteric left portal vein bypass was indicated as a surgical intervention and preventative measure for hepatic dysfunction in children with long-term EHPVO. Nevertheless, there is a lack Of published data confirming the extent of hepatic dysfunction, hypersplenism, and physical development in children with long-term follow-up. Method: We retrospectively verified the long-term outcomes in 82 children with EHPVO treated with ES protocol, focusing on mortality, control of bleeding, hypersplenism, and consequent hepatic dysfunction. Results: Of the children, 56% were free from bleeding after the initiation of ES. The most frequent cause of rebleeding was gastric varices (30%). Four patients had recurrent bleeding from esophageal varices (4.6%). Four patients underwent surgery as a consequence of uncontrolled gastric varices. There were no deaths. Most patients showed good physical development. We observed a mild but statistically significant drop in factor V motion, as well as leukocyte and platelet count. Conclusion: Endoscopic sclerotherapy is an efficient treatment for children with EHPVO. The incidence of rebleeding is low, and there was no mortality. Children develop mild liver dysfunction and hypersplenism with long-term follow-up. Only a few patients manifest symptoms of hypersplenism, portal biliopathy, or liver dysfunction before adolescence.

The universal newborn hearing screening in Brazil: From identification to intervention

Objective: The objective of the study is to investigate the results of the newborn hearing screening program carried out in a Public Hospital in Brazil, in the first 3 years regarding: (1) the prevalence of hearing impairment; (2) the influence of the universal hearing screening program on the age at which the diagnosis of hearing loss is defined; (3) the cost effectiveness of the program; (4) the outcomes, in terms of the age in which the hearing rehabilitation started. Methods: A descriptive study of the first 3 years after starting the universal newborn hearing screening in a Public Hospital of Bauru, Sao Paulo state, Brazil. The screening method consists of a two-stage screening approach with transient otoacoustic emissions (TOAE), conducted by an audiologist. If the outcome in the second-stage screening is REFER, the infant is submitted to diagnostic follow-up testing and intervention at the Audiology and Speech Pathology Clinic at the University of Sao Paulo, campus of Bauru. The evaluation of the costs of the universal newborn hearing screening program per each screened newborn (around 4000/year) was done based on a proposal by the National Center for Hearing Assessment and Management, of the Utah State University, United States of America. Results: 11,466 newborns were submitted to hearing screening, corresponding to 90.52% of the living newborns. The prevalence of sensorineural hearing loss was 0.96:1000. Of the 11 children with sensorineural hearing loss, eight children received hearing aids and five started the therapeutic process before the age of 1. Currently, four children between the ages of 11 months and 2 years old were submitted to cochlear implant surgery. The cost of hearing screening was US$7.00 and the annual cost of the universal newborn hearing screening program was US$26,940.47. Conclusion: The hospital-based universal newborn hearing screening carried out through the Brazilian National Health System is viable, with promising results. However, in a country such as Brazil, which presents large socio-economic differences, the same type of analyses should be performed in several regions, so as to take into account specific aspects, to implement the newborn hearing screening along with the Public System.

Impact of a nutritional counseling program on prevention of HAART-related metabolic and morphologic abnormalities

The advent of highly active antiretroviral therapy (HAART) improved HIV infection prognosis. However, adverse metabolic and morphologic effects emerged, highlighting a lack of investigation into the role of nutritional interventions among this population. The present study evaluated the impact of a nutritional counseling program on prevention of morphologic and metabolic changes in patients living with HIV/AIDS receiving HAART. A 12-month randomized clinical trial was conducted with 53 adults of both genders in use of HAART. Subjects were allocated to either an intervention group (IG) or a control group (CG). Nutritional counseling was based on the promotion of a healthy diet pattern. Anthropometrical, biochemical, blood pressure, and food intake variables were assessed on four separate occasions. Sub scapular skin-fold results showed a significant tendency for increase between time 1 (Mean IG = 14.9 mm; CG = 13.6 mm), time 3 (Mean IG = 16.7 mm; CG = 18.2 mm), and time 4 (Mean IG = 16.4 mm; CG = 17.7 mm). Lipid percentage intake presented a greater increase among controls (time 1 mean = 26.3%, time 4 mean = 29.6%) than among IG subjects (time 1 mean = 29.1%, time 4 mean = 28.9%). Moreover, participants allocated to the IG presented an increase in dietetic fiber intake of almost 10 grams. The proposed nutritional counseling program proved to be effective in improving diet by reducing fat consumption and increasing fiber intake.
