360度评价在住培学员岗位胜任力评价中的应用

目的运用360度评价对我院住培学员的岗位胜任力进行评价,对学员岗位胜任力的现状进行探讨分析。方法使用问卷调查表分别从专业基地教学主任、学员指导教师、同专业学员及学员本人的角度,对2017级222名住培学员的岗位胜任力进行360度评价,利用SPSS22.0对数据进行统计分析。结果连续两年的测评,住院学员8类岗位胜任力的自评和他评得分低于满分,学员在临床基本能力、医患沟通能力、掌握与运用医学知识、团队合作能力4项内容的评分,差异有统计学意义(P<0.05);同时学员在临床基本能力、医生职业精神与素质、医患沟通能力、掌握与运用医学知识、团队合作能力5项内容的评分较上一年相比,差异也有统计学意义(P<0.05)。结论调查结果提示360度评价可帮助住培学员提高岗位胜任力,后续培训应围绕调查结果和以岗位胜任力为导向来调整与设置,需增加人文属性内容的培训以及再量化培训测评内容、指标和进一步完善考评反馈机制。     

Unexpected Return for Follow-up During the First Year of Multidisciplinary Care May Be Predictive of Rapid Deterioration of Renal Function

Multidisciplinary predialysis education and team care (MDC) may slow the decline in renal function in patients with chronic kidney disease (CKD). However, associations between unexpected return during MDC and progression of renal dysfunction have not been characterized in patients with CKD. Our study aimed to determine the association between exacerbation of renal dysfunction and the frequency of unexpected return during follow-up.A total of 437 patients with CKD receiving multidisciplinary care between January 2009 and June 2013 at the Shin-Kong Wu Ho-Su Memorial Hospital were included in this retrospective observational cohort study, and multiple imputations were performed for missing data. The predictor was the frequency of unexpected return for follow-up during the first year after entering MDC. Main outcome was monthly declines in estimated glomerular filtration rates (eGFR). Moreover, the demographic data, comorbidities, history of medication, and routine laboratory data for patients with CKD were collected.Among all patients, 59.7% were male, the mean age at initiation of MDC was 69.4 ± 13.2 years, and the duration of follow-up was 21.4 ± 3.3 months. The subjects were divided into 2 groups according to frequencies of follow-up (≤4 and > 4 visits) during the 1st year of MDC. The patients with CKD were regularly followed up every 3 months as a part of MDC in our hospital, and patients who returned for more than 4 follow-up visits were included in the unexpected return group. In crude regression analyses, unexpected return was significantly associated with higher monthly declines of eGFR (β = 0.092, 95% confidence interval, 0.014–0.170). This association remained after adjustments for multiple variables, and subgroup analyses of unexpected return showed that male gender, older age, CKD stage 1 to 3, hypertension, history of coronary artery disease, and use of renin–angiotensin system blockade were significantly associated with declines in renal function.In conclusion, unexpected return for follow-up during the 1st year of MDC was significantly associated with the deterioration of renal function.     

User experiences with second-generation 32-gauge × 4 mm vs. thinner comparator pen needles: prospective randomized trial

Abstract

Objective

Two similarly designed studies compared user experiences with a second-generation extra-thin-wall, 5-bevel 32?G?×?4?mm pen needle (PN) with redesigned hub versus four thinner commercially available PNs.     

自发性高血压大鼠永久性脑缺血模型建立的研究

目的在比较自发性高血压大鼠(SHR)与同龄无高血压Wistar大鼠永久性大脑中动脉阻塞(pMCAO)后脑缺血损伤情况并初步分析其可能机制。方法雄性SHR和Wistar大鼠各30只分别随机分为:pMCAO模型6 h组、假手术6 h组、pMCAO模型24 h组、假手术24 h组和正常组(均n=6)。采用线栓法制作pMCAO模型,术后6、24 h对大鼠进行神经功能学评分后处死,制作脑冠状切片。术后6 h处死大鼠脑部切片行尼氏染色后在组织学层面上观察神经元损伤情况;术后24 h处死大鼠脑部切片行尼氏染色后计算脑梗死体积和水肿程度百分比。正常组脑部切片经苏木精-伊红染色后计算脑部小血管壁/腔比。结果术后6和24 h,不同品系大鼠神经功能学评分差异无统计学意义(P0.05);术后6 h尼氏染色示SHR神经元损伤重于Wistar大鼠。术后24 h SHR脑梗死体积百分比[(28.05±2.38)%]大于Wistar大鼠[(25.23±1.33)%],差异有统计学意义(P0.05)。两品系大鼠之间脑水肿程度差异无显著性。脑部小血管壁/腔比SHR[(11.46±3.74)%]较Wistar大鼠[(8.73±1.73)%]增大(P0.05)。结论 pMCAO术后SHR的脑缺血损伤程度重于Wistar大鼠,可能与高血压引起的脑侧支循环血管壁增厚、僵硬,自我调节能力降低有关。     

Family Caregivers' Subjective Caregiving Burden,Quality of Life,and Depressive Symptoms Are Associated With Terminally Ill Cancer Patients' Distinct Patterns of Conjoint Symptom Distress and Functional Impairment in Their Last Six Months of Life

Context

Family caregivers constitute a critical component of the end-of-life care system with considerable cost to themselves. However, the joint association of terminally ill cancer patients' symptom distress and functional impairment with caregivers' subjective caregiving burden, quality of life (QOL), and depressive symptoms remains unknown.

Necroptotic TNFα-Syndecan 4-TNFα Vicious Cycle as a Therapeutic Target for Preventing Temporomandibular Joint Osteoarthritis

Temporomandibular joint osteoarthritis (TMJOA) is a chronic degenerative disease for which the underlying mechanism still remains unclear. Compared with apoptosis and autophagy, necroptosis causes greater harm to tissue homeostasis by releasing damage-associated molecular patterns (DAMPs). However, the role of necroptosis and downstream key DAMPs in TMJOA is unknown. Here, rodent models of TMJOA were established by the unilateral anterior crossbite (UAC). Transmission electron microscopy (TEM) and immunohistochemistry of receptor interacting protein kinase 3 (RIPK3)/phosphorylation of mixed lineage kinase domain-like protein (pMLKL) were conducted to evaluate the occurrence of necroptosis in vivo. The therapeutic effects of blocking necroptosis were achieved by intra-articularly injecting RIPK3 or MLKL inhibitors and using RIPK3 or MLKL knockout mice. In vitro necroptosis of condylar chondrocyte was induced by combination of tumor necrosis factor alpha (TNFα), second mitochondria-derived activator of caspases (SMAC) mimetics and carbobenzoxy-valyl-alanyl-aspartyl-[O-methyl]- fluoromethylketone (z-VAD-fmk). The possible DAMPs released by necroptotic chondrocytes were screened by quantitative proteomics and blocked by specific antibody. Translucent cytosol, swollen organelles, and ruptured cell membranes, features of necroptosis, were frequently manifested in chondrocytes at the early stage of condylar cartilage degeneration in TMJOA, which was accompanied by upregulation of RIPK3/pMLKL. Inhibiting or knocking out RIPK3/MLKL significantly prevented cartilage degeneration. DAMPs released by necroptotic condylar chondrocytes, such as syndecan 4 (SDC4) and heat shock protein 90 (HSP90), were verified. Furthermore, blocking the function of SDC4 significantly attenuated the expression of TNFα in cartilage and synovium, and accordingly increased cartilage thickness and reduced synovial inflammation. Thus, the necroptotic vicious cycle of TNFα-SDC4-TNFα contributes to cartilage degeneration and synovitis, and can serve as a potential therapeutic target for treating TMJOA. © 2022 American Society for Bone and Mineral Research (ASBMR).
