RESUMO

Introduction: Aortic stiffness assessed by pulse wave velocity (PWV) is an important predictor to evaluate the risk of hypertensive patients. However, it is underutilized in clinical practice. We aimed to identify the optimal cutoff SAGE score that would indicate a risk PWV ≥ 10 m/s in Brazilian ambulatory hypertensive patients. Materials and methods: A retrospective cohort study. Patients underwent central blood pressure measurement using a validated oscillometric device from August 2020 to December 2021. A ROC curve was constructed using the Youden statistic to define the best score to identify those at high risk for PWV ≥ 10 m/s. Results: A total of 212 hypertensive individuals were selected. The mean age was 64.0 ± 12.4 years and 57.5% were female. The following comorbidities were present: overweight (47.6%), obesity (34.3%), and diabetes (25.0%). Most of the sample (68.9%) had PWV < 10 m/s. According to Youden's statistic, a cutoff point of 6 provided the optimal combination of sensitivity and specificity for identifying patients with a PWV ≥ 10 m/s. This cutoff achieved sensitivity of 97.0%, and specificity of 82.9%. In clinical practice, however, a cutoff point of 7 (where score values of at least 7 were considered to indicate high risk) had a positive likelihood ratio of 8.2 and a negative likelihood ration of 0.346, making this the ideal choice by accurately excluding patients who are less likely to have PWV ≥ 10 m/s. Conclusion: A SAGE score ≥7 identified Brazilian hypertensive patients with a high risk of PWV ≥ 10 m/s.

RESUMO

This review aimed to verify the effects of vitamin E supplementation on oxidative stress, inflammatory response, muscle damage, soreness, and strength in healthy adults after exercise. We searched the MEDLINE, EMBASE, SPORTDiscus, Cochrane CENTRAL, and Web of Science from inception to August 2023, with no language restrictions. We included randomized placebo-controlled trials evaluating the supplementation of vitamin E on the abovementioned outcomes after a bout of physical exercise in healthy participants (no restriction for publication year or language). Meta-analyses were conducted to compare vitamin E and placebo supplementations to obtain a 95% confidence interval (95%IC). Twenty studies were included (n=298 participants). The effect of supplementation was assessed between 0 h and 96 h after the exercise. Compared to placebo, vitamin E had no effects on lipid (95%IC= -0.09 to 0.42), protein (-2.44 to 3.11), SOD (-1.05 to 0.23), interleukin-6 (-0.18 to 1.16), creatine kinase (-0.33 to 0.27), muscle soreness (-1.92 to 0.69), and muscle strength (-1.07 to 0.34). Heterogeneity for the analyses on carbonyls, interleukin-6 (1 h and 3 h), and muscle soreness ranged between 70 to 94%. Supplementing with vitamin E should not be recommended to support the recovery process in healthy individuals after exercise, given the lack of efficacy in the analyzed variables following an exercise session.

RESUMO

Objective: The objective of the study was to assess the association of anthropometric measurements with endothelial function and arterial stiffness of eutrophic individuals and with overweight. Subjects and methods: A cross-sectional study was carried out with individuals with body mass index (BMI) between 18.5 kg/m2 and < 30 kg/m2, low to intermediate global cardiovascular risk scores, and aged ≥ 18 and < 60 years. We assessed the sociodemographic data, anthropometric variables (body weight, height, circumferences of the waist [WC], neck [NC], hip [HC], sagittal abdominal diameter [SAD], [BMI], waist-to-hip ratio [WHR], and waist-to-height ratio [WHtR]), biochemical parameters (lipid profile and nitric oxide), endothelial function (flow-mediated dilation [FMD], by ultrasound), and arterial stiffness (pulse wave velocity [PWV] and the amplification index [AIx@75] by oscillometry). Thirty-six individuals were included, 18 eutrophic and 18 with overweight, with a mean age of 37.5 ± 10.2 years, mostly at low cardiovascular risk (86.1%), female (80.6%), single (52.8%), employed with formal contracts (44.4%), and with over twelve years of education (88.9%). Results: The PWV presented positive and moderate correlation with the WC (r = 0.584; P = 0.001), WHR (r = 0.513; P = 0.001), and WHtR (r = 0.590; P = 0.001), and positive and low correlation with the NC (r = 0.372; P = 0.013) and SAD (r = 0.356; P = 0.033). Moreover, no anthropometric parameter presented a correlation with the AIx@75 or the FMD percentage in the total sample. Conclusion: Our findings show that in eutrophic individuals and with overweight the WC, WHR, WHtR, SAD, and NC were positively correlated with the PWV but not to the endothelial function in the overall sample. These are hypothesis-generating findings and they should be replicated in other studies.

RESUMO

Background:The combined supplementation of vitamins C and E potentially can mitigate oxidative stress (OS) and accelerate recovery following exercise. However, there is little evidence and a lack of consensus on the effects of these vitamins for this purpose. The objective of this systematic review was to summarize the evidence on the effects of the combined supplementation of vitamins C and E in OS, inflammatory markers, muscle damage, muscle soreness, and musculoskeletal functionality following acute exercise. Methods: The search was carried out from inception until March 2021, on MEDLINE, EMBASE, Cochrane CENTRAL, Web of Science, and SPORT Discus. We included placebo-controlled randomized clinical trials (RCTs) that evaluated the effects of combined supplementation of vitamins C and E in OS, inflammatory markers, muscle damage, muscle soreness, and muscle strength following a single bout of exercise. Random-effect meta-analyses were used to compare pre to post-exercise mean changes in subjects who received supplementation with vitamins C and E or placebo versus controls. Data are presented as standard mean difference (SMD) and 95% confidence interval (95% CI). Results: Eighteen RCTs, accounting for data from 322 individuals, were included. The use of vitamins attenuated lipid peroxidation (SMD= -0.703; 95% CI= -1.035 to -0.372; p < 0.001), IL-6 (SMD= -0.576; 95%CI= -1.036 to -0.117; p = 0.014), and cortisol levels (SMD= -0.918; 95%CI= -1.475 to -0.361; p = 0.001) immediately, and creatine kinase levels 48 h following exercise (SMD= -0.991; 95%CI= -1.611 to -0.372; p = 0.002). Supplementing the combination of vitamins had no effects on protein carbonyls, reduced/oxidized glutathione ratio, catalase, interleukin-1Ra, C-reactive protein, lactate dehydrogenase, muscle soreness, and muscle strength. Conclusion: Prior supplementation of the combination of vitamins C and E attenuates OS (lipid peroxidation), the inflammatory response (interleukin-6), cortisol levels, and muscle damage (creatine kinase) following a session of exercise.

RESUMO

INTRODUCTION: Coffee is one of the most consumed foodstuffs worldwide. Studies of coffee intake in healthy subjects have shown controversial effects on vascular function. However, little is known of coffee intake effects on the endothelium of overweight and obese individuals. OBJECTIVE: To investigate the acute effects of caffeinated and decaffeinated coffee intake on the endothelial function and arterial stiffness in overweight and obese individuals. METHODS: A randomized, double-blind, crossover clinical trial was designed to investigate the effects of regular caffeinated coffee and decaffeinated coffee on the endothelium. Each subject had both caffeinated coffee and decaffeinated coffee, separated by a washout period of seven days. The endothelial function was measured by flow-mediated dilation (FMD) assessed by ultrasound. Arterial stiffness was measured by an automatic oscillometric device. Blood samples were collected to assess the lipid and nitric oxide profiles. RESULTS: There were 18 subjects included in the study, aged 37.4 ± 10.0 years, with an average BMI of 28.96 ± 2.42, with the majority being female (61.1%). The caffeinated coffee increased central systolic blood pressure (P < 0.001), central diastolic blood pressure (P < 0.001) and pulse wave velocity (P < 0.001), but the decaffeinated coffee did not affect these variables. However, there was a better effect on FMD in the caffeinated coffee intake group (P = 0.014). CONCLUSION: In overweight and obese individuals, caffeinated coffee increased central blood pressure and pulse wave velocity but not the decaffeinated coffee. While caffeinated coffee showed an improvement on hyperemia-induced endothelial function. REGISTRATION NUMBER OF CLINICAL TRIAL: Platform of the Brazilian Registry of Clinical Trials under number RBR-65cxtr.

RESUMO

OBJECTIVES: The aim of this study was to verify the accuracy of the SARC-F and the SARC-CalF as screening tools for sarcopenia in community-dwelling older women ≥60 y of age. METHODS: This was a cross-sectional study evaluating a convenience sample of women ≥60 y of age, living in Southern Brazil. Sarcopenia was defined according to the criteria proposed in the latest European Working Group on Sarcopenia in Older People consensus (EWGSOP2). Appendicular muscle mass was assessed by dual-energy x-ray absorptiometry. Muscle strength was measured by handheld dynamometry, and physical performance through the 4-m gait speed test. The SARC-F questionnaire and SARC-CalF score for sarcopenia screening were also applied. RESULTS: We evaluated 288 participants, with a mean age of 67.6 ± 5.8 y. The frequency of probable and confirmed sarcopenia in the sample was 7.3% and 2.1%, respectively. The frequency of risk for sarcopenia assessed by the SARC-F was 4.5% and SARC-CalF 22.2%. Despite the excellent specificity (95.4%) demonstrated by the SARC-F, its sensitivity in identifying confirmed cases was null, whereas the SARC-CalF showed high sensitivity (83.3%) and good specificity (79%). CONCLUSION: The present study findings suggested that SARC-CalF may be able to outperform SARC-F as a sarcopenia screening tool in women ≥60 y of age even under the new EWGSOP2 criteria, the main determinant of which is strength as observed in studies based on the previous definition.

RESUMO

OBJECTIVES: There are many studies concerning sarcopenia prevalence from all over the world. However, to our knowledge, only two compared urban and rural sarcopenia and to date, none have been conducted in the Americas. The aim of this study was to evaluate the prevalence of sarcopenia in a convenience sample of women ≥60 y of age who underwent bone densitometry and live in urban and rural areas of southern Brazil. METHODS: This was a cross-sectional study comprising 205 women ≥60 y of age who had undergone bone densitometry. Sarcopenia was defined according to the criteria recommended by the European Working Group on Sarcopenia in Older People. The diagnosis combined the evaluation of muscle mass (assessed by dual-energy x-ray absorptiometry), muscle strength (measured using a manual digital dynamometer), and muscular performance (evaluated by the 4-m walking speed test). Sociodemographic data, smoking status, chronic conditions, number of falls and fractures in the past year, and level of physical activity also were collected. RESULTS: Sarcopenia was present in 2.4% of the total sample. Urban and rural populations significantly differed in terms of schooling (P < 0.001), occupation (P = 0.010), socioeconomic status (P = 0.001), and smoking status (P = 0.006). The environment in which the women lived was independently associated with sarcopenia (odds ratio, 9.561; 95% confidence interval, 1.021-89.523; P = 0.048). The prevalence of sarcopenia was significantly higher in the urban women than in the rural group (5.7 versus 0.7%, respectively; P = 0.047). After multivariate analysis, the environment of the women's residence remained independently associated with sarcopenia. CONCLUSION: Urban elderly women are more vulnerable to sarcopenia than rural elderly women.

RESUMO

ABSTRACT Objective: To investigate the association between body mass index (BMI) and bone mineral density (BMD) in postmenopausal women. Methods: Observational study with postmenopausal women who underwent bone densitometry in Palmeira das Missões - RS. Sociodemographic data, risk for osteoporosis and food intake were assessed through a specific form. BMI was calculated according to WHO criteria. The assessment of BMD was performed by dual-energy X-ray absorptiometry (DXA) and classified according to WHO. Statistical analysis was performed using prevalence ratios (PR) and their respective 95% confidence intervals for the factors studied. Variables associated with p < 0.20 with the different outcomes (osteopenia and osteoporosis) were included in a Poisson regression model with robust variance to adjust for potential confounding factors. A 5% significance level was considered. Results: 393 postmenopausal women with a mean age of 59.6 ± 8.2 years participated.After the adjustments, the normal weight women had 1.2 times the prevalence of osteopenia of obese women (PR = 1.2; CI 95% 1.3-1.5). Considering osteoporosis, the PR of euthophic women was twice the PR of obese women (PR = 2; CI 95% 1.4-2.9) and was 1.7 times greater for overweight group compared to obese category (PR = 1.7; CI 95% 1.2-2.5). Conclusion: Obese women had lower prevalence of osteopenia compared with normal weight subjects and also with lower prevalence of osteoporosis as compared to normal- and overweight women.


RESUMO Objetivo: Verificar a associação entre o índice de massa corporal (IMC) e a densidade mineral óssea (DMO) em mulheres pós-menopáusicas. Métodos: Estudo observacional, com mulheres pós-menopáusicas submetidas à densitometria óssea em Palmeira das Missões (RS). Dados sociodemográficos, de risco para a osteoporose e do consumo alimentar foram avaliados por meio de formulário específico. O IMC foi calculado de acordo com a Organização Mundial de Saúde (OMS). A avaliação da DMO foi feita por meio de absorciometria por dupla emissão de raios-X (DXA) e classificada de acordo com a OMS. A análise estatística foi feita por meio de razões de prevalência (RP) e os seus respectivos intervalos de 95% de confiança para os fatores em estudo. Variáveis que se associaram com p < 0,20 com os diferentes desfechos (osteopenia e osteoporose) foram incluídas em um modelo de regressão de Poisson com variância robusta para ajuste para potenciais fatores de confusão. Foi considerado um nível de significância de 5%. Resultados: Participaram 393 mulheres pós-menopáusicas, com média de 59,6 ± 8,2 anos.Após os ajustes, as mulheres eutróficas apresentaram 1,2 vez a prevalência de osteopenia das mulheres obesas (RP = 1,2; IC 95% 1,3-1,5). E em relação à osteoporose, no grupo das eutróficas a RP foi duas vezes a RP das obesas (RP = 2; IC 95% 1,4-2,9) e 1,7 no grupo com sobrepeso em relação à categoria obesidade (RP = 1,7; IC 95% 1,2-2,5). Conclusões: As mulheres obesas apresentaram menor prevalência de osteopenia em comparação com as eutróficas, bem como tiveram menor prevalência de osteoporose em comparação com as mulheres eutróficas e com sobrepeso.
