The Added Value of SARC-F to Prescreening Using FRAX for Hip Fracture Prevention in Older Community Adults

Objectives

To examine the potential added value of a simple 5-item questionnaire for sarcopenia screening (SARC-F) to the Fracture Risk Assessment Tool (FRAX) for hip fracture risk prediction, in order to identify at-risk older adults for screening with dual-energy x-ray absorptiometry (DXA).

Endostar,an Antiangiogenesis Inhibitor,Combined With Chemoradiotherapy for Locally Advanced Cervical Cancer

This phase II randomized clinical trial aimed to assess the efficacy and toxicity of Endostar, an antiangiogenesis inhibitor, combined with concurrent chemoradiotherapy (CCRT) for locally advanced cervical cancer (LACC). Patients with LACC were randomly assigned to either CCRT plus Endostar (CCRT+E arm) or CCRT alone (CCRT arm). All patients received pelvic intensity-modulated radiation therapy (IMRT) and brachytherapy. Weekly cisplatin was administered concurrently with IMRT. Patients in the CCRT+E arm also received concurrent Endostar every 3 weeks for two cycles. The primary endpoint was progression-free survival (PFS) and acute toxicities. The exploratory endpoint was the impact of vascular endothelial growth factor receptor-2 (VEGFR2) expression on long-term survival. A total of 116 patients were enrolled. Patients in the CCRT+E arm and in the CCRT arm had similar acute and late toxicity profile. The 1- and 2-year PFS were 91.4% versus 82.1% and 80.8% versus 63.5% (p=0.091), respectively. The 1- and 2-year distance metastasis-free survival (DMFS) were 92.7% versus 81.1% and 86.0% versus 65.1% (p=0.031), respectively. Patients with positive VEGFR2 expression had significant longer PFS and overall survival (OS) compared with those with negative VEGFR2 expression. Patients in the CCRT+E arm had significantly longer PFS, OS, and DMFS than those in the CCRT arm when VEGFR2 expression was positive. In conclusion, CCRT plus Endostar significantly improved DMFS but not PFS over CCRT alone. The addition of Endostar could significantly improve survival for patients with positive VEGFR2 expression.     

WHO药品预认证微生物实验室质量管理的要求与思考

目的:介绍世界卫生组织(WHO)对药品微生物检测实验室的预认证要求,推动我国药品检测质量管理体系的完善和发展。方法:从预认证实验室应遵循的质量管理原则出发,对照我国实验室ISO/IEC 17025体系要求,分析药品微生物检测实验室在质量管理中的不足。结果:预认证实验室更多地采纳了《药品生产质量管理规范》(GMP)的质量管理理念,而我国药品微生物检测实验室在记录与数据可靠性、基于风险的变更控制和偏差调查等方面的应用与实施还存在较大差距。结论:我国药品微生物检测实验室应学习和借鉴国内外GMP的质量管理经验,不断更新理念,改进质量管理体系,更多地以风险评估方式保障检测数据的可靠性。

Grappling with complexity: Medical students’ reflective writings about challenging patient encounters as a window into professional identity formation

Aim: Clerkship-specific interactive reflective writing (IRW)-enhanced reflection may enhance professional identity formation (PIF), a fundamental goal of medical education. PIF process as revealed in students? reflective writing (RW) has been understudied.

Methods: The authors developed an IRW curriculum within a Family Medicine Clerkship (FMC) and analyzed students? reflections about challenging/difficult patient encounters using immersion-crystallization qualitative analysis.

Results: The qualitative analysis identified 26 unique emergent themes and five distinct thematic categories (1. Role of emotions, 2. Role of cognition, 3. Behaviorally responding to situational context, 4. Patient factors, and 5. External factors) as well as an emergent PIF model from a directed content analysis. The model describes students? backgrounds, emotions and previous experiences in medicine merging with external factors and processed during student?patient interactions. The RWs also revealed that processing often involves polarities (e.g. empathy/lack of empathy or encouragement/disillusionment) as well as dissonance between idealized visions and lived reality.

Conclusions: IRW facilitates and ideally supports grappling with the lived reality of medicine; uncovering a “positive hidden curriculum” within medical education. The authors propose engaging learners in guided critical reflection about complex experiences for meaning-making within a safe learning climate as a valuable way to cultivate reflective, resilient professionals with “prepared” minds and hearts for inevitable challenges of healthcare practice.
