Assessment of body composition in the prader-willi syndrome using bioelectrical impedance

The accurate assessment of body composition is of importance in the Prader-Willi syndrome. Many techniques are not applicable due to ethical or practical reasons. However, the bioelectrical impedance technique is a rapid, painless, noninvasive method of estimating total body water and hence, fat-free mass in obese children and adolescents. We have compared estimates of total body water derived from bioelectrical impedance with actual measurements taken, using H₂¹⁸O dilution, in 14 children with Prader-Willi syndrome. Existing equations for predicting total body water from impedance showed a bias to underestimate actual measures of body water. There were positive correlations between the degree of underestimation with age and body fatness. It is possible that changes in body shapes influence bioelectrical impedance measurements in obese individuals, and that a prediction equation based upon a normal population will not be applicable to obese individuals. © 1992 Wiley-Liss, Inc.     

Correlations between bone mineral density and demographic, lifestyle, and biochemical variables in community-dwelling Japanese women 69 years of age and over

Introduction A few epidemiologic studies have comprehensively attempted to identify risk factors for low bone mineral density (BMD) in elderly Asian women. The purpose of this study was to identify demographic, lifestyle, and biochemical factors correlated with BMD in elderly Japanese women 69 years of age and over.Methods The study design was cross-sectional. The subjects were 583 ambulatory women aged 69 years and over, and their average age was 74.3 (SD 4.4) years. Predictor variables were age, reproductive history, anthropometric indices, grip strength, calcium intake, lifestyle information, and serum 25-hydroxyvitamin D, 1,25-dihydroxyvitamin D (1,25(OH)₂D), osteocalcin (OC), and undercarboxylated osteocalcin (ucOC) values. The outcome variable was forearm BMD measured with a DTX-200 osteometer.Results Simple linear regression analyses showed that BMD was significantly positively associated with body height, weight, body mass index, grip strength, serum albumin concentration, and “housework,” and negatively associated with age, years since menopause, age at menarche, number of children, serum 1,25(OH)₂D concentration, serum OC concentration, and ucOC concentration. The stepwise multiple regression analysis showed that weight (β=0.00316, SE=0.00028, R²=0.180), age (β=−0.00321, SE=0.00050, R²=0.108), log-transformed serum OC (β=−0.0445, SE=0.0064, R²=0.053), log-transformed serum 1,25(OH)₂D (β=−0.0401, SE=0.0074, R²=0.050), “farmwork” (β=0.00904, SE=0.00426, R²=0.005), and serum 25(OH)D concentration (β=0.000281, SE=0.000120, R²=0.003) were significantly associated with BMD.Conclusion It was concluded that body weight is a major predictor of forearm BMD among the factors measured in this study in independent Japanese women 69 years of age and over and that serum 1,25(OH)₂D concentration may be associated with cortical BMD. Maintenance of body weight is very important for maintaining BMD in this population, unless a large weight aggravates obesity-related diseases. A follow-up study is needed to confirm these findings.

体重指数对全膝关节置换术后功能的影响

目的回顾性分析体重指数(BMI)对骨关节炎(OA)患者全膝关节置换术(TKA)后功能的影响.方法由同一组医生使用同一种假体对320例(520膝)骨关节炎患者行全膝关节置换.按体重指数分为4组非肥胖组(BMI＜25.0 kg/m2)、超重组(BMI 25.1～27.0 kg/m2)、肥胖组(BMI 27.1～30.0kg/m2)和病理性肥胖组(BMI＞30.0 kg/m2),分别记录术前及随访时HSS膝评分、功能评分、膝关节最大屈曲、伸直度数和并发症.结果术前超重组、肥胖组和病理性肥胖组功能评分较非肥胖组低(P＜0.05),但膝评分差异无显著性.通过平均28.3个月的随访,无论膝评分和功能评分各组术后均明显提高,各组提高的幅度比较差异无显著性.虽然超重组、肥胖组和病理性肥胖组术后最大屈曲、伸直度数较非肥胖组小,但是改善幅度仍相当,差异无显著性(P＞0.05).肥胖组和病理性肥胖组围手术期并发症明显增高(P＜0.05),在总共93例(181膝)中,有14膝(9.2%)出现伤口并发症,其中1膝(0.5%)感染,感染发生于术后10周内,与伤口并发症有关;2膝(1.3%)内侧副韧带损伤.超重组166例(258膝)中有6膝(2.3%)出现伤口并发症,无感染及内侧副韧带损伤病例.非肥胖组61例(81膝)中有1膝(1%)出现伤口并发症,无感染及内侧副韧带损伤病例.结论TKR是进展期OA患者有效的治疗措施,肥胖并不是膝关节置换手术的障碍.但围手术期并发症增多,包括伤口愈合、感染、内侧副韧带损伤,应注意伤口缝合技术和保护内侧副韧带.     

Post-prandial cardiovascular responses in man after ingestion of carbohydrate,protein or fat

Changes in cardiac output and in superior mesenteric arterial flow were followed with Doppler ultrasound techniques in five young, healthy persons for 2 h after ingestion of medium-sized (4 MJ), fluid meals containing either carbohydrate, protein, fat or water only. Measurements were carried out before meals and at regular post-meal intervals, during which mean arterial blood pressure was also followed. All energy-containing meals caused marked and gradually developing post-prandial increases in cardiac output as well as in superior mesenteric arterial flow. The maximum flow levels were reached in the course of 30–60 min and maintained until the observations ended after 2 h. The intake of water caused no such flow increases. There were considerable interpersonal variations in the size and in the speed of development of the flow increases after the three types of energy-containing meals. The flow-increasing effects of the three meal types were not significantly different, even if the most marked increases (median values about 1 1 min^-1 for both cardiac output and superior mesenteric arterial flow) occurred after carbohydrate meals. The marked effects on circulation of the three food components were also revealed in the calculated, integrated amounts of ‘extra’ cardiac output and superior mesenteric arterial flow observed in the course of the 2 h following the meal. Values of more than 100 1 for such ‘extra’ flows were seen after carbohydrate meals. The marked ingestion-released increase in blood flow to the splanchnic organs is apparently partly met by an increase in cardiac output, and partly by some redistribution of flow, which benefits the digestive system.
