RESUMEN

Objective: Arterial hypertension (AH) is a risk factor for cardiovascular diseases (CVD). We sought to evaluate the association between two adiposity indices (visceral adiposity index [VAI] and lipid accumulation product [LAP]) with traditional markers of cardiometabolic risk in hypertensive patients. Materials and methods: This is a cross-sectional study with 1,273 subjects with hypertension treated as outpatients at a university hospital. The VAI and LAP were calculated using formulas stratified by sex. Cardiometabolic risk variables were considered: overweight, risk for waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHA), and altered biochemical test values. The predictive effect of independent variables on outcomes was assessed by multivariate linear regression analysis. There was statistical significance when p ≤ 0.05. Results: Higher cardiometabolic risk (according to BMI, WHR, WHA, and altered biochemical parameters) was associated with higher values of VAI and LAP with statistical significance (p ≤ 0.05). The regression models used explained 30.7% and 10.5% of the changes in LAP and VAI, respectively. Conclusion: LAP and VAI are associated with cardiometabolic risk parameters in the individuals evaluated, suggesting that these indices can be used to screen for CVD risk in individuals with AH.

RESUMEN

OBJECTIVE: Cardiovascular diseases represent the main cause of death in chronic kidney disease (CKD). We aimed to evaluate the prevalence and association of the hypertriglyceridemia-waist phenotype (HWP) and visceral adiposity index (VAI) with cardiometabolic risk factors (CR) in patients with CKD on hemodialysis (HD). METHODS: The study is based on a cross-sectional design with 265 HD patients in two cities in northeastern Brazil. The VAI was calculated considering the variables body mass index (BMI), waist circumference (WC), triglycerides (TG) and high density lipoprotein cholesterol (HDL-c). HWP was defined as the concomitant elevation of WC and TG. The Poisson Regression Model with robust variance estimation was adjusted considering a hierarchical approach for explanatory variables. Prevalence ratios (PR) were also estimated. The level of significance adopted was 5%. RESULTS: In our study HWP and VAI prevalence's were 29.82% and 58.49%, respectively. In the final model, there was an association between VAI and female gender (PR = 1.46; p < 0.0001) and high body fat (% BF) (PR = 1.33; p < 0.0019). HWP was associated with females (PR = 1.80; p = 0.002), alcohol consumption (PR = 1.58; p = 0.033), obesity (PR = 1.89; p = 0.0001), high %BF (PR = 1.76; p = 0.012) and reduced HDL-c (PR = 1.48; p = 0.035). CONCLUSION: The HWP stood out as the association with more CR factors, representing a promising method for tracking cardiometabolic risk in HD patients, mainly female.

RESUMEN

INTRODUCTION: Few studies have investigated the performance of screening tools in truly sarcopenic individuals, especially subgroups of this population, or in comparison to previous and current criteria for the definition of sarcopenia. OBJECTIVES: Evaluate the performance of SARC-F and SARC-CalF in screening for sarcopenia in patients with Parkinson's disease (PD) in comparison to the diagnostic criteria proposed by the 2010 (1) and 2019 (2) European Working Group on Sarcopenia in Older People (EWGSOP). METHODS: A methodological, cross-sectional study was conducted involving male and female patients ≥60 years of age diagnosed with PD in outpatient care. The risk of sarcopenia was assessed using the SARC-F and SARC-CalF questionnaires, the latter of which includes the calf circumference as an additional item. RESULTS: Sixty patients were evaluated (mean age: 68.9 ± 6.5 years). The prevalence of sarcopenia was 21.7% according to EWGSOP-2 and 55.0% according to EWGSOP-1. Positive screening for sarcopenia was 30% according to the SARC-F and 36.7% according to SARC-CalF. The sensitivity of the SARC-F for the detection of sarcopenia was 27.2% and 23.1% using the criteria of the 2010 and 2019 consensuses, respectively. The comparative analysis of the SARC-CalF revealed a better performance in the diagnostic discrimination with the addition of calf circumference, with sensitivity ranging from 53.8 to 54.5%. Higher sensitivity was found on items addressing the ability to stand up from a chair and climb stairs (69.2%) and the occurrence of falls (76.9%) compared to the use of the complete questionnaire. CONCLUSION: Relatively low sensitivity and an underestimation of sarcopenia were found in the analysis of the SARC-F as a screening tool for sarcopenia. Thus, a significant number of sarcopenic patients would not be identified using this screening tool alone. The SARC-CalF performed better than the SARC-F.

RESUMEN

INTRODUCTION: The aim of this study was to determine the effects of bariatric surgery and weight loss on body composition, serum sclerostin and physical performance. METHODS: Seventy-three consecutive patients (36 non-surgical controls and 37 who underwent bariatric surgery) were evaluated by means of laboratory tests, multifrequency bioelectrical impedance analysis (BIA), total-body dual-energy X-ray absorptiometry (DXA), gait speed and handgrip strength. RESULTS: The differences between non-surgical and surgical patients were as follows: body mass index (BMI) 42.9 ± 5.7 vs 34.8 ± 6.0 kg/m2 (p < 0.001); handgrip strength 31.3 ± 7.0 vs 27.1 ± 9.3 kg (p < 0.033); skeletal muscle mass index (SMI)-BIA 12.3 ± 1.2 vs 10.6 ± 1.2 kg/m2; fat-free mass index (FFMI)-BIA 21.9 ± 1.9 vs 18.9 ± 2.1 k/m2 (p < 0.001 for all comparisons); Baumgartner-DXA 10.8 ± 1.5 vs 9.0 ± 1.4 kg/m2 (p < 0.001); fat mass BIA 55.4 ± 12.5 vs 36.8 ± 9.6; fat mass DXA 54.3 ± 12.38 vs 35.1 ± 7.5 kg (p < 0.001 for both comparisons) and serum sclerostin 30.9 ± 31.9 vs 26.9 ± 21.1 pmol/L (p = 0.516). Positive correlation was found between BIA and DXA: SMI × Baumgartner (r = 0.842; p < 0.001) and fat mass (r = 0.970; p < 0.001). Gait speed was relatively preserved in sleeve gastrectomy (SG) compared with Roux-en-Y gastric bypass (RYGB) (1.2 ± 0.3 and 0.9 ± 0.1 m/s; p = 0.038). CONCLUSION: Bariatric surgery leads to lower values of lean and fat mass and of handgrip strength with no differences in serum sclerostin concentrations. There was a positive correlation between BIA and DXA for fat and lean mass parameters. Physical performance was better after SG than in RYGB.
