2014—2019年广州市耐多药肺结核管理策略实施效果分析

目的 评估广州市耐多药肺结核治疗管理策略实施的效果,为结核病防治提供依据。方法 选取2014年7月1日至2019年12月31日于广州市胸科医院纳入耐多药肺结核高危人群筛查的2417例患者为调查对象,收集其人口学特征及临床诊疗资料,获得耐多药肺结核者671例,截止到2019年12月31日有治疗结局者352例。其中,广州户籍患者(简称“户籍患者”)由专家组讨论治疗方案,纳入定点科室住院和耐多药门诊随访;非广州户籍患者(简称“非户籍患者”)自行选择医院诊疗。同时,收集2018年1—5月期间162例耐多药肺结核患者医疗费用调查资料。分析调查对象治疗及转归情况,影响治疗转归的因素,以及医疗经济负担。结果 671例耐多药肺结核患者中户籍患者303例,检出率为21.37%(303/1418),低于非户籍患者的36.84%(368/999),差异有统计学意义(χ²=69.93,P<0.01)。352例有治疗结局患者中治疗成功200例(56.82%),出现不良结局者152例(43.18%)。单因素分析显示,户籍患者治疗成功比例(69.23%,108/156)明显高于非户籍患者(46.94%,92/196),差异有统计学意义(χ²=17.59,P<0.01);41~60岁组和≥61岁组患者出现治疗不良结局的比例明显高于治疗成功组[52.00%(78/150)vs. 48.00%(72/150);56.82%(25/44)vs. 43.18%(19/44)],差异有统计学意义(χ²=18.45,P<0.01);2016年1月1日及以后开始治疗的患者治疗成功的比例(61.71%,166/269)明显高于此时间以前开始治疗者(40.96%,34/83),差异有统计学意义(χ²=11.13,P<0.01)。多因素logistic回归分析显示,出现治疗不良结局的危险因素为非户籍[OR(95%CI)=4.01(2.37~6.79)]、年龄>40岁[41~60岁组:OR(95%CI)=4.08(1.05~15.96);≥61岁组:OR(95%CI)=6.51(1.48~28.60)];而2016年1月1日及以后开始治疗为保护因素[OR(95%CI)=0.30(0.17~0.52)]。户籍患者经济负担总费用[M(Q₁,Q₃)]为24674(17466,49920)元,明显低于非户籍患者[100215(63858,133720)元],差异有统计学意义(Z=-7.80,P<0.01)。结论 广州市耐多药肺结核管理策略可提高户籍患者治疗成功率,降低患者经济负担;建议推广对耐多药结核病患者由专家组讨论方案,定点收治和随访,减免费用等管理策略。     

The effect of the Kinesio Tape on the muscle power performance of elite weightlifters

IntroductionTo investigate the effect of the Kinesio Tape on the muscle power of the elite weightlifters.MethodsA randomized controlled trial, single blind. Forty-two male weightlifters were randomly assigned to the experimental Kinesio Tape and sham Kinesio Tape groups of the study. The participants then performed a single leg vertical jump and a single leg horizontal jump with three attempts of each to obtain the measurement of muscle power. Outcome measures were included single-leg vertical countermovement jump, estimated peak power, and single-leg horizontal countermovement jump.ResultSignificant effect of Kinesio Tape on horizontal jumps distance among the weightlifters in the experimental group (p = 0.002). The study showed that the vertical jump height (p = 0.433), estimated peak power (p = 0.542) and horizontal jump distance (p = 0.841) measurements did not improve significantly between the groups at level p = 0.05.ConclusionThere is a small and better improvement noticed on the outcome measurements after Kinesio Tape application, which may be considered clinical importance for the sport. However, there was no statistically significant effect of Kinesio Tape between the groups.     

A profile of the Youth Olympic Taekwondo Athlete

Our study aims to identify trends in anthropomorphic attributes and competitive strategies of successful (medalists) versus non medalist young Olympic Taekwondo competitors by gender in terms of body mass, body-mass index (BMI) and fighting technique at the Youth Olympic Games 2010. Results were then compared to adult Taekwondo Olympic athletes in 2000, 2004 and 2008. Data on 96 Taekwondo athletes were obtained from the official Youth Olympic website. A LOGIT analysis was performed on the following six independent variables: height, body mass, body mass index, gender, techniques used to score, and warnings obtained during a match. The study did find some differences between winners and non-winners for males and female, although none of the differences were statistically significant. Consequently, training personnel may enhance winning potential of Taekwondo competitors by focusing on offensive versus defensive techniques and improving the quality of punching.     

Validity and reliability of the TargetScan ISSF Pistol & Rifle application for measuring shooting performance

Several technologies, with varying economic costs, are used to measure the performance of Olympic sport shooters, including electronic targets, laser systems, and mobile phone applications. Nevertheless, the International Shooting Sport Federation (ISSF) does not currently accept any mobile applications as valid measurement systems. The objective of the study was to check the validity and reliability of the TargetScan ISSF Pistol & Rifle application, an automatic mobile application for measuring the performance of shooters via image analysis. A total of 1440 shots were fired by 24 shooters (720 shots each for the air rifle and air pistol events), and the target sheets were analyzed with the application installed on an iPhone X. The official competition results and the measurements from the application were then compared. The results showed an almost perfect reliability for air pistol shots (ICC = .999) and no significant differences between the official average scores and those measured by the application. The reliability was also high for air rifle shots (ICC = .998), but the average scores registered by the application were statistically lower than the official results. We concluded that TargetScan ISSF Pistol & Rifle is a low‐cost, valid, and reliable application for measuring amateur and semi‐professional shooting performance which may be useful to shooters, coaches, clubs, and federations worldwide.
