BACKGROUND Prophylactic antibiotics have significantly led to a reduction in the risk of postoperative surgical site infections(SSI)in orthopaedic *** aim of using antibiotics for this purpose is to achieve serum and tissue drug levels that exceed,for the duration of the operation,the minimum inhibitory concentration of the likely organisms that are *** antibiotics reduce the rate of SSIs in lower limb arthroplasty from between 4%and 8%to between 1%and 3%.Controversy,however,still surrounds the optimal frequency and dosing of antibiotic *** To evaluate the impact of introduction of a weight-adjusted antibiotic prophylaxis regime,combined with a reduction in the duration of administration of post-operative antibiotics on SSI incidence during the 2 years following primary elective total hip and knee arthroplasty METHODS Following ethical approval,patients undergoing primary total hip arthroplasty(THA)/total knee arthroplasty(TKA)with the old regime(OR)of a preoperative dose[cefazolin 2 g intravenously(IV)],and two subsequent doses(2 h and 8 h),were compared to those after a change to a new regime(NR)of a weight-adjusted preoperative dose(cefazolin 2 g IV for patients120 kg)and a post-operative dose at 2 *** primary outcome in both groups was SSI rates during the 2 years *** A total of n=1273 operations(THA n=534,TKA n=739)were performed in n=1264 *** was no statistically significant difference in the rate of deep(OR 0.74%(5/675)vs NR 0.50%(3/598);fishers exact test P=0.72),nor superficial SSIs(OR 2.07%(14/675)vs NR 1.50%(9/598);chi-squared test P=0.44)at 2 years *** propensity score weighting and an interrupted time series analysis,there was also no difference in SSI rates between both groups[RR 0.88(95%CI 0.61 to 1.30)P=0.46].CONCLUSION A weight-adjusted regime,with a reduction in number of post-operative doses had no adverse impact on S

目的尽管太极拳(TC)可以预防老年人跌倒,但其有效动作仍不清楚,这很大程度上限制了太极拳的临床应用。本研究旨在比较太极拳下肢运动(TC LEE)、8式太极拳(8式TC)和牵拉练习对改善老年人平衡相关功能的效果。方法本研究共招募了102名符合纳排标准的受试者。所有受试者被随机分配到TC LEE组(n=40)、8式TC组(n=31)和牵拉组(n=31),并接受相应的干预。干预总时长16周,每周3次,每次1小时。本研究的评价指标包括Berg平衡量表(BBS)、起立与行走测试(TUG)、静态站立时中心压力(COP)数据、踝关节本体感觉和髋关节外展力矩。所有受试者在干预前和干预后分别进行了评价指标的收集。使用重复测量方差分析比较了3个组在干预前后的评价指标。使用非劣检验,比较了两种TC干预组在BBS和TUG测试上的变化。结果与牵拉组相比,两干预组干预后在所有评价指标上均有显著改善(P<0.002)。BBS变化量的95%置信区间(CI)上限(-0.8～1.3分)在等效边界(1.8分)内。而TUG变化量的95%CI上限(0.1～2.1 s)超出等效边界(0.7 s),TC LEE组TUG变化分数更大。结论TC LEE可以改善老年人平衡相关功能,并且在改善TUG方面比8式TC效果更好,说明腿部动作可能是太极拳的关键,可在临床应用上有所侧重。

欧洲最适合隐居的地方在哪里？近日Lonely Planet公布的名单中，阿尔卑斯山脚下的库夫施泰因榜上有名。古典音乐环绕小镇，而走进大自然的方式有无数种：夏季徒步，冬季滑雪……库夫施泰因，奥地利西部的一个美丽小镇。得益于德、奥边界的地理之势，无论从慕尼黑还是萨尔茨堡出发，都只需乘车约1小时就能到达。小镇夹在阿尔卑斯山的一个河谷，碧绿草坪、原始森林和清澈湖水环绕四周，八个村庄点缀其间，从高空俯瞰，犹如散落的珍珠。
