ABSTRACT
Abstract@#School based lifestyle interventions have many advantages, which can effectively reduce the prevalence of overweight and obesity, improve children and their families knowledge of overweight and obesity, and enhance their cognition of behaviors related to energy balance. Moreover, it can improve the level of cardiometabolic risk (CMR). By searching PubMed, CNKI and Wanfang databases, the article review the effects of school based physical activity and dietary interventions on children s blood pressure, blood lipids, blood glucose, and other CMR indicators, and analyze the differences among different groups of people, such as gender, age, and race, in order to provide the evidence for future school based intervention studies on overweight and obesity in children.
ABSTRACT
OBJECTIVE: To find out the incidence of early DVT in patients after knee arthroscopic surgery with routine use of tourniquet and discuss the associate risk factors. METHODS: Total 1 561 cases undertaken primary knee arthroscopic surgery was reviewed retrospectively from January 2013 to January 2017, including 651 males and 910 females with a mean age of (65.7±8.7) years old ranging from 62 to 81 years old. The cases were divided into DVT group and non-DVT group according to ultrasonic Doppler after surgery. The DVT occurrence rate was calculated and the basic information was analyzed to filter out the risk factors through univariate analysis and multivariate analysis. The cases of DVT group received 6 months anticoagulation therapy and were undertaken a follow-up of 1, 3, 6 months by ultrasonic Doppler. RESULTS: Out of the 1 561 cases, 226(14.5%) developed early DVTs following surgery, 32(2.0%) cases had the proximal DVTs, and 194(12.4%) cases had the isolated distal DVTs. The risk factors include the age(>=73 years), female sex and gastrocnemius vein dilation (GVD), hypertension, longer tourniquet time(>=74 min). The GVD and the length of tourniquet time was considered to be the best predictor of the early DVTs after surgery, with an odds ratio of 2.337 (95% CI, 1.644-3.611) and 2.112 (95%CI, 1.452-3.301). Twelve isolated distal DVTs(6.6%) and 11 proximal DVTs(36.7%) still showed thrombus at 6-month follow-up, but exhibit decreased size and at various stage of resolution. CONCLUSIONS: The incidence of early DVTs after knee arthroscopic surgery is 14.5%. Out of all risk factors, the GVD and the length of tourniquet time have the best power for prediction of DVTs after surgery. Both proximal and distal DVTs received accepted outcomes after formal therapy.
