RÉSUMÉ
Objective To examine the relationship between upper leg length (ULL) and metabolic syndrome (MetS) in older adults.Methods Data was collected from National Health and Nutritional Examination Survey (NHANES, 2009–2010). 786 individuals (385 males and 401 females) who were 60 years of age or older were included in this analysis. MetS was defined as having at least three of following conditions, i.e., cen-tral obesity, dyslipidemia, insulin resistance, and hypertension based on National Cholesterol Education Program guidelines. ULL was grouped into gender-specific tertiles.Results328 (41.7%) of participants were categorized as having MetS (38.7% in men and 49.1% in women,P = 0.002). Compared to individuals in the 1st tertile (T1) of ULL, those in the 3rd tertile (T3) had lower levels of triglycerides (120.8 vs. 153.1 mg/dL,P = 0.045), waist circumference (100.7vs. 104.2 cm,P = 0.049), and systolic blood pressure (126.7vs. 131.4 mmHg, P = 0.005), but higher levels of high-density-lipoprotein cholesterol (58.1vs. 52.4 mg/dL,P = 0.024). The odds ratios (95% CI) of MetS from multivariate logistic regression were 0.57 (0.32–1.03) for individuals in the T2 of ULL and 0.39 (0.24–0.64) for individuals in the T3 of ULL, respectively (P-value for the trend 0.022).Conclusions ULL was negatively associated with MetS in older adults. Further research is needed to identify potential mechanisms.
RÉSUMÉ
Objective To evaluate the clinical effect of popliteal artery perforator-based sural neurovascular flap for repairing soft tissue defects in middle and distal upper leg.Methods Between December,2011 to September,2015,18 cases with skin soft tissue defects on the middle and distal upper leg were treated with popliteal artery perforator-based sural neurovascular flap,in which 12 cases were males,and 6 cases were females.The age was from 24 to 55 years,with the average age of 35.9 years.The size of tissue defects ranged from 3.0 cm × 3.0 cm to 7.0 cm × 9.0 cm.Results All flaps survived completely in 18 cases,1 case of marginal infection heated after dressing,and the rest cases in Ⅰ healing.The outline and function of survived flap were satisfactory during 3-16 months follow-up,with two-point discrimination of 4.0-10.0 mm.Conclusion The anterograde sural neurovascular flap based on the popliteal artery perforator provides a practical option for covering tissue defects in middle and distal upper leg.This flap is characteristiced by reliable blood supply without sacrificing main vesses,good contour and texture,in addition,the operation is easy of handling.
