Effects of exercise dose and type during breast cancer chemotherapy on longer-term patient-reported outcomes and health-related fitness: A randomized controlled trial

The Combined Aerobic and Resistance Exercise (CARE) Trial compared different types and doses of exercise performed during breast cancer chemotherapy. Here, we report the longer-term follow-up of patient-reported outcomes, health-related fitness and exercise behavior at 6, 12 and 24 months postintervention. A multicenter trial in Canada randomized 301 breast cancer patients initiating chemotherapy to thrice weekly, supervised exercise consisting of a standard dose of 25–30 min of aerobic exercise (STAN; n = 96), a higher dose of 50–60 min of aerobic exercise (HIGH; n = 101) or a combined dose of 50–60 min of aerobic and resistance exercise (COMB; n = 104) performed for the duration of chemotherapy (median of 17 weeks). Primary outcomes were patient-reported outcomes including quality of life, cancer-related symptoms and psychosocial outcomes. Secondary outcomes were objective health-related fitness (assessed at 12 months only) and self-reported exercise behavior. A total of 269 (89.4%) participants completed patient-reported outcomes at all three follow-up time points and 263 (87.4%) completed the health-related fitness assessment at 12-month follow-up. COMB was significantly superior to (i) STAN for sleep quality at 6-month follow-up (p = 0.027); (ii) HIGH for upper body muscular endurance at 12-month follow-up (p = 0.020); and (iii) HIGH for meeting the resistance exercise guideline at 6-month follow-up (p = 0.006). Moreover, self-reported meeting of the combined exercise guideline during follow-up was significantly associated with better patient-reported outcomes and health-related fitness. Performing combined exercise during and after breast cancer chemotherapy may result in better longer-term patient-reported outcomes and health-related fitness compared to performing aerobic exercise alone.     

Polypharmacy among patients with multiple sclerosis: a qualitative systematic review

ABSTRACT

Objectives: The consequences of polypharmacy (intake of ≥ 5 drugs) are diverse, including drug interactions, rising costs and side effects. Risk groups for polypharmacy are multimorbid and chronically ill people, such as patients with multiple sclerosis (MS). MS is the most common neuroimmunological disease in young adults worldwide. We aimed to provide a systematic overview of the current research status regarding frequency and predictors of polypharmacy in MS patients.

Methods: A systematic literature search in the databases PubMed, Cochrane Library and Scopus was carried out according to the PRISMA guidelines. English and German original research articles were included.

Results: Seven studies fulfilled the inclusion criteria of this review, while the research objectives and methods were very heterogenous. The polypharmacy rates in these studies ranged from 15% to 59%. Polypharmacy correlated with comorbidities, increased disability, cognitive deficits, increased hospitalization, higher relapse rate and lower quality of life.

Conclusions: In MS patients, polypharmacy is common and closely associated with health issues. There is a great need for research in this area, especially regarding longitudinal changes in drug utilization. Effective networks between physicians and pharmacists are needed to optimize medication management for patients and to achieve the best possible therapy results.     

薄层色谱法在当前中药质量标准中的应用探讨

薄层色谱鉴别在历版《中国药典》中的应用经历了从无到有、从少到多的过程；而薄层扫描含量测定在最近几版《中国药典》中的应用比例逐渐降低。随着对中药质量标准体系要求的进一步提高，薄层色谱法的不足之处陆续显现，如仪器普及率低、设备并不简单、结果重复性和稳定性较差、鉴别速度及准确性不及高效液相色谱法、展开剂毒性大等，逐渐不合时宜。在制定中药质量标准时，研究者不应该墨守成规，薄层色谱鉴别也不应该是雷打不动的定性鉴别必备选项。高效液相色谱法具备完全取代薄层色谱法的可行性，薄层色谱法可作为高效液相色谱法的补充。为充分降低检测成本、缩短检测周期、提高鉴别效率，笔者建议中药质量标准体系应该大幅减少薄层色谱鉴别方法的应用，增加高效液相特征图谱鉴定，尽量做到“一个条件，一张图谱”；除非确有必要，《中国药典》等国家质量标准体系应将薄层色谱鉴别作为推荐方法，而非强制标准。     

卒中溶栓绿色通道优化研究及实施效果分析

目的探讨卒中溶栓绿色通道的构建、整改对发病到实施溶栓的时间（onset to treatment time,OTT）、院内溶栓时间（door to needle time，DNT）、临床疗效及预后的影响。 方法收集通过绿色通道溶栓患者118例的临床资料，以时间为界分为对照组57例和观察组61例。比较2组OTT、DNT、DNT≤60 min比率、临床疗效、并发症发生情况、美国国立卫生研究院卒中量表（the National Institutes of Health Stroke Scale,NIHSS）评分、Barthel指数（Barthel index，BI）评分、改良Rankin量表（Modified Rankin Scale,mRS）评分等。 结果观察组OTT、DNT短于对照组，DNT≤60 min比例高于对照组（P＜0.01）。经过溶栓治疗72 h后，观察组临床疗效优于对照组，总有效率高于对照组（P＜0.01）。2组总并发症发生率和病死率差异均无统计学意义（P＞0.05）。2组NIHSS评分均呈逐渐降低趋势，观察组NIHSS评分低于对照组，组间、时点间、组间·时点间交互作用差异均有统计学意义（P＜0.01）。2组BI评分均呈逐渐升高趋势，观察组BI评分高于对照组，组间、时点间、组间·时点间交互作用差异均有统计学意义（P＜0.01）。治疗3个月以后，观察组mRS评分明显低于对照组，≤2分比例高于对照组（P＜0.01）。 结论卒中溶栓绿色通道的建立，能够显著缩短OTT、DNT，提高临床疗效，减轻残障程度，取得良好的社会效益。

以脾胃为中心的葛根相关配伍对糖尿病心肌病大鼠受损心肌线粒体的改善作用

目的:观察葛根及其配伍对糖尿病心肌病(DCM)大鼠心肌线粒体质量变化的影响,探寻治疗糖尿病心肌病的最优配伍及机制。方法:采用链脲佐菌素腹腔注射进行模型大鼠制备,并将60只成模大鼠随机分为模型组6.5 g/(kg·d)、达美康组16.7 mg/(kg·d)、葛根组1.04 g/(kg·d)、葛芪组2.6 g/(kg·d)、葛参组2.6 g/(kg·d)、葛蒌组4.48g/(kg·d)及葛芪参蒌组7.6 g/(kg·d)各8只,同时选取空白大鼠8只,为对照组6.5 g/(kg·d)。各组依据上述剂量,以相应药物持续灌胃9周后,对比各组心肌线粒体超微结构变化、心肌线粒体膜电位变化及心肌ATP变化情况。结果:电镜显示各药物干预组心肌线粒体超微结构较模型组均有不同程度的改善,其中葛芪参蒌组改善效果最为明显,与空白组无明显差异; 流式细胞仪检测显示:各干预组波峰均在模型组、空白组之间; 其中葛芪参蒌组、葛参组、葛根组波峰位于达美康组右侧; 葛芪组、葛蒌组则位于达美康组左侧; 以葛芪参蒌组波峰与空白组最为接近。心肌ATP浓度检测显示:各中药干预组心肌ATP浓度均较模型组有所提升(P<0.05),其中葛芪参蒌组ATP值较其余各干预组提升最为明显(P<0.05),但仍低于空白组(P>0.05)。结论:葛根相关配伍均能够对心肌线粒体结构、心肌线粒体膜电位进行正向调控,进而使因糖尿病心肌病导致的心肌线粒体受损得以恢复,其中以益气、化瘀、祛痰三法合用的组方原则进行配伍的葛芪参蒌方改善效果最优。可见其治疗机制可能是通过益气、化瘀、祛痰的协同作用,正向调控心肌线粒体质量而达到治疗目的。
