过氧化物酶体增殖物激活受体γ在脓毒症中的研究进展

背景 现已证实脓毒症是由感染因素诱发的全身性炎症反应综合征,在病程中表现为机体和病原体相互作用导致的促炎和抗炎反应不平衡. 目的 过氧化物酶体增殖物激活受体-γ(peroxisome proliferator activated receptor-γ,PPAR-γ)作为一种配体激活的核受体转录因子,与配体结合后作用于炎性信号转录途径的多个环节,抑制炎症反应,进而对脓毒症有一定的保护作用.因此,了解PPAR-γ在脓毒症中的研究现状以及未来发展趋势是十分必要的. 内容 PPAR-γ在缓和自身免疫性疾病、抗炎、抑制超敏反应、抗肿瘤及移植排斥中发挥重要的作用.针对PPAR-γ在脓毒症发病机制及治疗的研究作一综述. 趋向 PPAR-γ已成为炎症研究的方向,由于PPAR-γ结构与功能的复杂性,其作用机制尚未完全清楚,但随着对PPAR-γ研究的深入,有望为临床提供新的治疗方案.     

Who Is Responsible? A Man With Dementia Wanders From Home,Is Hit by a Train,and Dies

The impact of dementia and Alzheimer's disease extends far beyond the healthcare needs of the person with dementia. As the disease progresses, individuals with dementia often require ongoing formal or informal care for their basic daily routine because of behavior changes and continuing loss of cognitive function. Most of the care for people with dementia takes place at home, and the unpaid, informal caregivers are often spouses or other relatives. Providing long-term informal care at home for someone with dementia is psychologically, physically, and financially draining. The tragedy described in this case elucidates the far-reaching societal impact of dementia care and the implicit health policy considerations.In 2007, a 91-year-old Japanese man with dementia was in the care of his wife when he wandered from home, was hit by a train, and died, immediately affecting the Central Japan Railway Company operations and, subsequently, legal practice as well as Japanese elder care policy. The railway sued the man's wife and son for negligence and lost revenue, winning both trials at the local and district courts. This ruling shocked families and caregivers in Japan, where care for elderly parents traditionally falls on the oldest son, and brought attention to the complex issues related to dementia care. A decade later, we revisit this case to provoke a renewed dialogue about the matrix of responsibilities and liabilities associated with caregiving; to illuminate the unmet needs of the person with dementia, as well as his or her informal caregivers; and the financial implications related to long-term care policy. We close with 2 practical suggestions which preserve the dignity of the individual and provide reassurance for caregivers.     

Quality Indicators of Primary Care Provider Engagement in Nursing Home Care

The initiative described here aims to identify quality indicators (QIs) germane to the international practice of primary care providers (PCP) in post-acute and long-term care in order to demonstrate the added value of medical providers in nursing homes (NHs). A 7-member international team identified and adapted existing QIs to the AMDA competencies for medical providers. QI sources included the ACOVE 3 Quality Indicators (2007), NH Quality Indicators (2004), NH Residential Care Quality Indicators (2002), and AGS Choosing Wisely (2014). We recruited a technical expert panel (TEP) consisting of 11 panelists from the US, Canada, and the European Union, selected for their knowledge and leadership in post-acute and long-term care. The TEP, using a RAND Modified Delphi approach, provided pre-meeting ratings, discussed items in-person for clarification, and re-rated items following discussion. When panelists rated more than 1 option for a particular QI as valid and feasible, the most stringent option was selected for inclusion in the final candidate set of QIs. Panelists confidentially rated an initial 103 items on validity and feasibility of implementation. During the meeting, panelists added 18 QIs and modified 18. In post-meeting analysis, we eliminated 7 QIs rated not valid and 11 QIs for which a more stringent QI was rated valid and feasible. This resulted in a final set of 95 QIs rated valid and feasible and 8 rated valid but not feasible. This set of QIs for PCPs in the NH identified practices in which provider engagement adds value through expertise in geriatric syndromes, employing evidence-based practice, advocating for residents, delivering person-centered care, facilitating advance care planning, and communicating effectively to coordinate care. Next steps include pilot testing and evaluating the association between adherence to QIs, PCP staffing models, and better outcomes.     

养老机构志愿者预立医疗照护计划培训效果评价

目的 开展养老机构志愿者预立医疗照护计划培训并评价其效果。方法 应用基于Bloom目标教学理论构建的养老机构志愿者预立医疗照护计划培训内容,结合《预立医疗照护计划》知识教育手册、《我的五个愿望》手册、案例视频等教具,通过角色扮演、案例讨论等方式对53名养老机构志愿者进行培训。培训前后使用养老机构志愿者预立医疗照护计划知信行及自我效能问卷对志愿者进行调查,根据志愿者角色扮演表现评价其预立医疗照护计划沟通技能。结果 培训前后志愿者预立医疗照护计划认知、态度、行为意愿及自我效能差异有统计学意义(P<0.05,P<0.01),培训后75.47%志愿者预立医疗照护计划沟通技能达合格及以上水平。结论 预立医疗照护计划培训能改善养老机构志愿者的预立医疗照护计划知信行及自我效能感,培养其预立医疗照护计划沟通能力。
