Associação entre consumo alimentar e atividade física com a síndrome metabólica em mulheres na pós-menopausa

Post-menopause is characterized as the period beginning one year after the permanent cessation of menstrual cycles, which is typically related to medical disorders that, in association with Metabolic Syndrome (MS), represent a set of cardiovascular risk factors. Objective: To assess dietary intake and the prevalence of metabolic syndrome in postmenopausal women, according to the level of physical activity. Methods: The sample consisted of 82 women, evaluated in the Northern Zone of the city of Natal / RN who were participants in the Natal Active Program. People completed a Food Frequency Consumption Questionnaire (FFCQ) and were interviewed about physical activity. Anthropometric measurements and biochemical tests were used to diagnose MS (Metabolic Syndrome). Result: The active women consumed more protective foods (flaxseed, nuts, whole wheat bread, brown rice and olive oil) than inactive women. Risky foods (sugar, crackers, white bread, white rice, margarine and beef) were consumed more by the group of inactive women. The prevalence of MS was higher in inactive women (53.30%) than in physically active women (46.70%). Conclusion: Active post-menopausal women had a higher daily intake of protective foods in relation to cardiovascular disease, while the inactive post-menopausal women had higher intake of risky foods for such diseases

Prevenção da síndrome metabólica em crianças obesas: uma proposta de intervenção

OBJETIVO: Analisar o efeito de 12 semanas de intervenção envolvendo prática de atividade física, orientações alimentar e psicológica sobre fatores de risco para o desenvolvimento da síndrome metabólica em crianças e adolescentes obesos. MÉTODOS: Estudo longitudinal com 23 crianças e adolescentes obesos, com idade entre seis e 16 anos (12,0±3,2 anos). Foram mensurados: gordura corporal total e de tronco, glicemia, colesterol total e triglicérides, pressão arterial sistólica e diastólica. Os jovens foram submetidos a três sessões semanais de 60 minutos de exercício físico (atividades esportivas recreativas, ginástica, circuitos e caminhadas), durante 12 semanas. O teste do qui-quadrado foi usado para comparar dados categóricos daqueles que apresentaram valores acima das recomendações para cada fator de risco. O teste t para dados pareados foi aplicado para comparar os dois momentos do estudo. RESULTADOS: em indivíduos com alterações metabólicas no início do estudo, observou-se, após a intervenção, a diminuição de 11,6% na glicemia (105 para 93mg/dL; p=0,046) e de 24,9% no triglicérides (217 para 163mg/dL; p=0,013); porém, não houve diferenças na pressão arterial e no colesterol total. CONCLUSÕES: O programa de exercício físico aplicado nas crianças e adolescentes foi eficiente para melhorar os valores de glicemia e triglicérides.

Síndrome metabólica em adolescentes do sexo feminino com sobrepeso e obesidade

OBJETIVO: Avaliar parâmetros bioquímicos e fisiológicos em adolescentes do sexo feminino com sobrepeso/obesidade ou com peso corporal normal e avaliar se fatores de risco cardiovascular, postulados como componentes da síndrome metabólica, já estão presentes nessa faixa etária. MÉTODOS: Estudo transversal, tendo-se comparado a totalidade de meninas com idades entre 12 e 18 anos de um colégio de Ribeirão Preto, divididas em dois grupos: sobrepeso/obesidade (n=30) e controle (n=39). de cada menina, foram avaliados parâmetros antropométricos (peso, estatura, dobras cutâneas, circunferências do abdome e do quadril) e bioquímicos (glicose, insulina, lipidograma, ureia, creatinina, fibrinogênio, PAI-1, ferritina, sódio e microalbuminúria). RESULTADOS: As adolescentes com sobrepeso/obesidade apresentaram níveis maiores de pressão arterial, glicose, triglicérides, ácido úrico, PAI-1, fibrinogênio e insulina e níveis menores de colesterol-HDL em relação ao grupo controle. A análise de alterações e formação de clusters de fatores de risco demonstrou que 76,7% das adolescentes do grupo sobrepeso apresentaram dois ou mais fatores de risco relacionados à síndrome metabólica, enquanto 79,5% das adolescentes do grupo controle apresentaram nenhuma ou apenas uma alteração. Os parâmetros microalbuminúria e ferritina sérica não apresentaram alterações e diferenças entre os grupos. CONCLUSÕES: Adolescentes do sexo feminino com sobrepeso/obesidade já apresentam hipertensão, dislipidemias, disfibrinólise, hiperinsulinemia e clusters de fatores de risco cardiovascular.

Análise da função dos músculos do quadril em portadores de síndrome da dor patelofemural

The Patellofemoral pain syndrome is defined as a fore or retro patellar pain and it has multifactorial etiology, where the bad patellar alignment is the most acceptable hypothesis. However proximal factors to the knee, as the debility of the muscles of the hip, have been demonstrated as a contributing factor to the appearing of that syndrome. Purpose: To evaluate if exists a relation between the hip muscles performance and the development of the SDPF. Methods: Thirty women took part in this study. They were divided in two groups; a control group (fifteen asymptomatic subjects) and an experimental group (fifteen subjects with the diagnosis of SDPF). The muscle performance was evaluated in an isokinetic dynamometer, where it was verified the peak torque (PT), PT to body weight, PT time and the agonist/antagonist relation. It was also analyzed the electromyographic activity of the middle gluteus. The data was analyzed by the not paired t test at a significance level of 5%. Results:. Didn t have significant difference to the PT of the abductor muscles (p = 0,46) and lateral rotators of the hip (p = 0,17) between groups. Also didn t have significant difference to the PT values by the body weight, to these muscle groups either (p = 0,10 e p = 0,11, respectively). Didn t have significant difference between the amplitude of the signal (p = 0,05) and the onset of medium gluteus (p = 0,25) between the groups. Conclusion: In the experimental conditions realized, the study didn t demonstrate a relation between performance the hip muscles behavior and the development of the SDPF

Efeitos da inclinação da esteira na marcha de crianças com síndrome de down

Background: Down syndrome (DS) is a genetic alteration characterized by being a nonprogressive congenital encephalopathy. Children with DS have hypotonia and developmental delays that interfere in the movement`s acquisition for these children. Objective: Analyze the effects of treadmill inclination on angle and spatiotemporal gait characteristics of these individuals. Methodology: We studied 23 subjects of both sexes, with ages ranged between 05 and 11 years, they presented ability to walk on level 5 classified according to the Functional Ambulation Category (FAC). Initially held a subjective evaluation of balance through a questionnaire (Berg Balance Scale-BBS) then the kinematic gait analysis was realized on a treadmill first, without inclination and then, with inclination of 10%, using the motion system analysis Qualisys System. Data analysis was done using BioStat 5.0 attributing significance level of 5%. Normality of data was verified using D'Agostino test and later was applied paired t-test to compare data in two experimental conditions. Results: There was a statistically significant difference in the spatiotemporal variables: reduction in the cadence (from 108.92 ± 39.07 to 99.11 ± 27.51, p <0.04), increase in cycle time (from 1.24 ± 0.27 to 1.36 ± 0.34, p = 0.03 ) and increase in time to take stock (from 0.77 ± 0.15 to 0.82 ± 0.18, p <0.001). Angular variables that showed statistically significant increasing were: the hip in the initial contact (12.23 ± 4.63 to 18.49 ± 5.17, p <0.0001) and max. flexion in balance (12.96±4:32 to 19.50 ± 4.51, p <0.0001 ), knee in the initial contact (15.59 to ± 6.71 to 21.63 ± 6.48, p <0.0001), the ankle in the initial contact (-2.79 ± 9.8 to 2.25 ± 8.79, p <0.0001), max dorsiflexion in stance (4.41 ± 10.07 to 7.13 ± 11.58, p <0.0009), maximum plantar flexion in the pre-assessment of the ankle joint (increase of -6.33 ± 8.77 to -2.69 ± 8.62, p <0.0004).Conclusions: The inclination acts in a positive way for angular and spatiotemporal features gait of children with Down syndrome, demonstrating possible benefit of using this surface in the gait rehabilitation of children with Down Syndrome

Efeito imediato da estimulação elétrica neuromuscular seletiva do músculo VMO em pacientes com síndrome da dor femoropatelar

Patellofemoral pain syndrome (PFPS) is described as anterior or retropatellar pain knee in the absence of other pathologies and is frequently associated with dysfunction of the vastus medialis oblique (VMO). However, several studies have demonstrated the inability to selectively activate this muscle through exercise. To evaluate the effect of Neuromuscular Electrical Stimulation (NMES) selective VMO in women with syndrome. We evaluated thirty-eight women: twenty in the control group (24.15 ± 2.60 years) and eighteen diagnosed with PFPS (25.56 ± 3.55 years). Both groups were evaluated before and after a protocol of electro stimulation. To measure for comparing groups before and after treatment, we assessed the extensor torque concentric and eccentric knee through an isokinetic dynamometer, the intensity (Root Mean Square - RMS) and the onset of activation (onset) of VMO compared to the vastus lateralis (VL) in two types of exercise: open and closed kinetic chain. . Statistical analysis was performed using SPSS 15.0, with a significance level of 5%. Results: Our data showed an increase in the intensity of activation (RMS) of the VMO muscle after NMES in both study groups. During concentric contraction the RMS of the VMO before the NMES was 105.69 ± 32.26 μV and after a single intervention was 122.10 ± 39.62 μV (p = 0.048) for the control group. In the group with PPS, we found a similar behavior, with RMS of the VMO before NMES of 96.25 ± 18.83 μV and 139.80 ± 65.88 μV after the intervention (p = 0.0001). However, there was no evidence in the RMS value of VL muscle. The onset was calculated by subtracting the onset of VL by the onset of VMO. For the group with PFPS, the onset before the intervention was -0.007 ± 0.14 ms, indicating a delay of the VMO relative to VL, and after NMES was 0.074 ± 0.09 ms (p = 0.016), showing an activation previous VMO to VL. The same occurred for the control group. We also observed that NMES increased knee extensor power during the concentric contraction in both groups. Before the intervention the mean power was 28.97 ± 9.01 W for the PPS group and after NMES was 34.38 ± 7.61 W (p = 0.0001). Conclusion: We observed an increase in electromyographic activity of the VMO and also an anticipatory effect of this muscle

Fatores de risco para síndrome metabólica em cadeirantes: jogadores de basquetebol e não praticantes

A atividade física tem sido sistematicamente estudada como fator preventivo no acometimento de enfermidades crônico-degenerativas, especialmente a síndrome metabólica e doenças cardiovasculares. Sedentarismo está relacionado à diminuição ou ausência de parâmetros mínimos de exigência física diária além do estado de repouso, sendo este fortemente associado à redução na condição de saúde dos indivíduos portadores de deficiência física. As respostas metabólicas do organismo mediante a ausência de determinada musculatura, ou sua inatividade pela falta de estímulos, conduzem a diferenças significativas na estruturação da composição corporal. Esta pesquisa teve como objeto o exercício físico regular e a condição de saúde de indivíduos portadores de deficiência física, através da determinação do perfil antropométrico e bioquímico sangüíneo, e ainda pela determinação da prevalência de fatores de risco para síndrome metabólica. Foram estudados 27 homens com paraplegia (T2-L1), portadores de seqüelas de poliomielite ou amputados, divididos em jogadores de basquetebol cadeirantes (JBC) e não jogadores de basquetebol cadeirantes (NJBC). Os JBC apresentaram circunferência de cintura menor comparada aos NJBC, 76,40±8,44 e 89,25±9,73 cm respectivamente (p<0,05). A pressão arterial sistólica foi significativamente maior nos NJBC 123,33±13,70 e 114,00±9,85 mmHg para JBC (p<0,05), não sendo verificada diferença para PAD. Os NJBC apresentaram valores superiores aos JBC para a bioquímica sangüínea de glicemia, TG, CT e frações, exceto para HDL-C (p<0,05). Os indivíduos NJBC apresentaram alta prevalência para fatores de risco da SM, sendo hipertensão arterial prevalente em 58,33% dos indivíduos, dislipidemia de HDL-C presente em 50% e circunferência de cintura acima da normalidade em 41,66%. Os achados do presente estudo sugerem um papel importante do exercício físico na prevenção da síndrome metabólica, embora estudos adicionais devam ser realizados para a melhor compreensão dos mecanismos que promovem a saúde dos deficientes físicos ativos.

Síndrome da fragilidade e fatores associados em idosos comunitários do município de Santa Cruz RN

The frailty in the elderly is characterized by decreased physiological reserves, and is associated with increased risk of disability and high vulnerability to morbidity and mortality. This study is part of a multicentric project on Frailty in Elderly Brazilians (REDE FIBRA). Aims: to investigate characteristics, prevalence and associated factors related to frailty. Metodology: We interviewed 391 elderly patients aged 65 years, selected randomly. Data collection was performed using a multidimensional questionnaire containing information about socio-demographic and clinical variables. To characterize the frail elderly, was considered the phenotype proposed by Fried. Data were analyzed using descriptive statistics, bivariate analysis (χ ²) and binary logistic regression. Results: The prevalence of frailty was 17.1%. In the final model of multivariate analysis, was obtained as factors associated with frailty: advanced chronological age (p <0.001), have comorbidity (p <0.035), show dependence on performing basic activities of daily living (p <0.010) and instrumental (p <0.003) and have poor perception of health status (p <0030). Conclusions: The factors associated with frailty suggest a predictive model helping to understand the syndrome, guiding actions that minimize adverse effects on the aging process

Sono e síndrome da fragilidade em idosos residentes em instituições de longa permanência

Introduction: The aging process causes quantitative and qualitative changes in sleeping. Such changes affects more than half of the adults above 65 years old, that live in the community and 70% of the institutionalized, a great negative impact in their quality of life. One of the pathological displays of aging, that share some characteristics with sleeping disorders and predict similar results, is the Frailty Syndrome, that characterize the most weakened and vulnerable elderly. The way sleeping disorders play a role in the frailty pathogeneses remains uncertain. Objective: Evaluate the relation between the sleeping and the frailty syndrome on institutionalized elderly. Methodology: A transversal study was performed with 69 elderly in institutions in the city of João Pessoa PB. Were used the Pittsburgh Sleeping Quality Index and actigraphy to subjective and objective variables, respectively, and questionnaires and specific tests to frailty phenotype variant (Fried Frailty Criteria). In the statistic analysis were used the Pearson correlation test, Chi Square and One-way ANOVA test, with Tukey-Krammer posttest. Subsequently, a Simple Linear Regression model was built. On every statistical analysis were considered a confidence interval of 95% and a p < 0,05. Results: The sample was characterized by the prevalence of the frail (49,3%), women (62,3%), single (50,7%) and 77,52 (±7,82).The frail elderly obtained the worst sleeping quality 10,37 (±4,31) (f = 4,15, p = 0,02), when compared with the non-frail. The sleep latency influenced more the frailty (R2 = 0,13, β standard = 1,76, β = 0,41, p = 0,001). Weren t found differences between the standard resting-activity variable and the frailty phenotype categories. Conclusion: Sleeping alterations, including bad sleeping quality, prolonged sleep latency, low sleep efficiency and day drowsiness, influenced the frailty in institutionalized elderly

Apoio social e síndrome da fragilidade em idosos residentes na comunidade

Introduction: The frailty in the elderly is the result of a complex interplay between many social and clinical factors involved in its genesis. Although there is an understanding of its association with increased risk of adverse clinical outcomes, still it is unclear whether this syndrome can be aggravated due to lack of social support. So, the objective of this study was to analyze the association between social support and frailty syndrome in elderly community residents. Materials and methods: Observational analytical cross-sectional study, with a sample of 300 elderly living in the city of Natal-RN. Were collected informations about socialdemographic, economics and physical health data. The Social support was assessed by the status of cohabitation; marital status; contact frequency and diversity rate; received and given attendance frequency rate; and Map Minimum Relations of the Elderly. The frailty was assessed using the following criteria: unintentional weight loss, weakness, low physical activity, exhaustion and Slowness. To observe any possible associations, we performed the Pearson chi-square test, the Student t test and multivariate analysis using binary logistic regression, adopting a significance level of 5%. Results: It was observed that there were no associations of frailty with the social support variables, except for housekeeping mode (p = 0.046) of the MMRI. For the sociodemographic, economic, physical health and social support data, only age (p <0.001), sedentary lifestyle (p = 0.002) and poor perceived health (p = 0.001) were the ones that remained in the logistic regression model, with strong association for the presence of frailty. Conclusion: Among the variables related to social support, only to help with housekeeping was significantly associated with frailty. However, more studies need to be developed to characterize the social vulnerability, as well as health services need to recognize the importance of social support as an integral part of care for the elderly

Estudo da imunoexpressão de RANKL e OPG, do índice angiogênico (CD34) e da presença de miofibroblastos (α-SMA) em ceratocistos odontogênicos isolados e associados à síndrome de Gorlin

The odontogenic keratocysts are distinguished from other odontogenic cystic lesions by their potentially aggressive clinical behavior and association, in some cases, with Gorlin syndrome. Studies have suggested that syndrome keratocysts, in comparison with sporadic lesions, have higher growth and infiltration capacity and higher recurrence tendency. The aim of this study was to analyze, by means of immunohistochemistry, the expressions of receptor activator of nuclear factor κB ligand (RANKL) and osteoprotegerin (OPG), the angiogenic index (CD34) and the presence of myofibroblasts (α-SMA) in primary and recurrent sporadic keratocysts and in keratocysts associated with Gorlin syndrome. The sample was composed by 30 sporadic keratocysts (22 primary and 8 recurrent) and 22 syndrome keratocysts. In the epithelium and in the fibrous capsule of the lesions, the immunoexpression of RANKL and OPG was evaluated by determination of the percentage of positive cells, according to the following scores: 0 (less than 10% of positive cells), 1 (11% - 50% of positive cells), 2 (51% - 75% of positive cells) and 3 (more than 76% of positive cells). In addition, cases were classified according to the RANKL score/ OPG score ratio, as follows: RANKL > OPG, RANKL < OPG, and RANKL = OPG. The angiogenic index was analyzed by counting the microvessels immunoreactive to anti-CD34 antibody in 5 fields (200). The analysis of myofibroblasts was performed by counting the cells immunoreactive to anti-α-SMA antibody in 10 fields (400). The analysis of the expressions of RANKL and OPG in the epithelial lining and in the fibrous capsule did not reveal significant differences between groups (p > 0.05). Regarding the RANKL/ OPG ratio in the epithelial lining, most sporadic primary (54.5%) and syndrome lesions (59.1%) showed RANKL < OPG ratio and RANKL = OPG ratio, respectively (p > 0.05). With respect to the RANKL/ OPG ratio in the fibrous capsule, the majority of sporadic primary (81.8%) and sporadic recurrent lesions (75.0%) and most syndrome lesions (45.5%) showed RANKL = OPG ratio (p > 0.05). The mean number of microvessels was 69.2 in sporadic primary lesions, 67.6 in recurrent lesions, and 71.6 in syndrome lesions, with no significant differences between groups (p > 0.05). The mean number of myofibroblasts was 34.4 in sporadic primary lesions, 29.3 in recurrent lesions, and 33.7 in syndrome lesions, with no significant differences between groups (p > 0.05). In conclusion, the results of the present study suggest that the differences in the biological behavior between sporadic keratocysts and keratocysts associated with Gorlin syndrome may not be related to the expressions of RANKL and OPG, the RANKL/ OPG ratio, the angiogenic index or the number of myofibroblasts in these lesions

A memória de curto prazo e a síndrome de down: a relação entre contextos de desenvolvimento

Down syndrome (DS) is one of the most frequent causes of intellectual disability, affecting one in every 600 to 1000 live births. Studies have demonstrated that people with DS have a lower capacity for short-term memory (STM) and working memory (WM), which affects their capability to learn new words and to follow spoken instructions, specially when they involve multiple information or consecutive orders/orientations. It seems that the basis of the learning process, as it happens with language and mathematics comprehension and reasoning, relies in the STM and WM systems. Individuals with DS are increasingly included in mainstream education, and yet, very few researches have been conducted to investigate the influence of memory development and the type of enrollment (regular school and special school). This study investigated the relationship between the type of school enrollment with the performance on STM tests and also, the relationship of this performance with early stimulation (ES). The tests used in the first research were the digit span, free recall, word recognition and subtests of the Wechsler Intelligence Scale for Children Third Edition (WISC-III). Individuals enrolled in the regular schools group had higher scores on the digit span test and the subtests of the WISC-III. In the free recall and recognition tests, no differences were found. This study indicates that the type of enrollment might influence the memory development of individuals with DS and clearly points the need for future investigations. In the second research, the tests used were the digit span, free word recall and subtests of the WISC-III. The test results showed better performance by adults that received ES before six months of age. The studies showed improvement in STM both in people who attended or were attending regular school, as well as those who benefited from ES before six months of age. However, some issues still need to be better understood. What is the relation between this stimulation with the individual s education? Since ES may reflect a greater family involvement with the individual, what is the role of emotional components derived from this involvement in the cognitive improvement? These and other questions are part of the continuity of this study
