Evidence-based strategies to reduce the incidence of postoperative delirium: a narrative review

Delirium is one of the most commonly occurring postoperative complications in older adults. It occurs due to the vulnerability of cerebral functioning to pathophysiological stressors. Identification of those at increased risk of developing delirium early in the surgical pathway provides an opportunity for modification of predisposing and precipitating risk factors and effective shared decision-making. No single delirium prediction tool is used widely in surgical settings. Multi-component interventions to prevent delirium involve structured risk factor modification supported by geriatrician input; these are clinically efficacious and cost effective. Barriers to the widespread implementation of such complex interventions exist, resulting in an ‘implementation gap’. There is a lack of evidence for pharmacological prophylaxis for the prevention of delirium. Current evidence suggests that avoidance of peri-operative benzodiazepines, careful titration of anaesthetic depth guided by processed electroencephalogram monitoring and treatment of pain are the most effective strategies to minimise the risk of delirium. Addressing postoperative delirium requires a collaborative, whole pathway approach, beginning with the early identification of those patients who are at risk. The research agenda should continue to examine the potential for pharmacological prophylaxis to prevent delirium while also addressing how successful models of delirium prevention can be translated from one setting to another, underpinned by implementation science methodology.     

日本居家安宁疗护服务体系构建经验及其对我国的启示

21世纪的日本"少子高龄化"特征明显，发展居家安宁疗护、构建完备的居家安宁疗护服务体系，是日本卫生服务提供体制改革的重要方向。本文介绍了日本居家安宁疗护的含义与理念，以及关于居家安宁疗护服务提供机构、提供人员、提供内容及费用保障的法律规定，提示我国在条件成熟时应尽快健全安宁疗护相关立法，在卫生服务提供体系框架下实现居家安宁疗护的稳定发展，建立并强化安宁疗护过程中的协作机制，并为居家安宁疗护提供必要的经费保障，通过完善的制度设计保障老年人"居家善终"的权益。     

Multicompartment systems: A putative carrier for combined drug delivery and targeting

In this review, we discuss recent developments in multicompartment systems commonly referred to as vesosomes, as well as their method of preparation, surface modifications, and clinical potential. Vesosomal systems are able to entrap more than one drug moiety and can be customized for site-specific delivery. We focus in particular on the possible reticuloendothelial system (RES) – mediated accumulation of vesosomes, and their application in tumor targeting, as areas for further investigation.     

ECFS standards of care on CFTR-related disorders: Updated diagnostic criteria

This paper is the first in a series providing updated guidance on the definition, evaluation and management of people with a Cystic Fibrosis Transmembrane conductance Regulator (CFTR)-Related Disorder (CFTR-RD). The need for this update relates to more precise characterisation of CFTR gene variants and improved assessment of CFTR protein dysfunction. The exercise is co-ordinated by the European CF Society Standards of Care Committee and Diagnostic Network Working Group and involves stakeholder engagement. This first paper was produced by a core group using an extensive literature review and papers graded for their quality. Subsequent wider stakeholder agreement was achieved.The definition of a CFTR-RD remains “a clinical condition with evidence of CFTR protein dysfunction that does not fulfil the diagnostic criteria for CF”. Clearer guidance on CFTR dysfunction and relevant CFTR variants will be provided. Thresholds for clinical presentations are presented and the paradigm that pathobiological processes may be evident in more than one organ is agreed. In this paper we reflect on the early patient journey, highlighting that CF specialists as well as other relevant specialists should be involved in the care of people with a CFTR-RD.     

以患者为中心的护理模式在腹腔镜胆囊切除术中的应用及对患者应激反应的影响

目的 探讨以患者为中心的护理模式在腹腔镜胆囊切除术中的应用效果及对患者应激反应的影响。方法 选取2019年3月至2021年3月于我院行腹腔镜胆囊切除术的64例患者,按照入组单双顺序平均分为观察组(以患者为中心的护理模式)与对照组(常规急诊护理)各32例。比较两组的生理应激反应、心理应激反应和术后恢复情况。结果 干预后,观察组的胰岛素、皮质醇水平及HAMA、 HAMD评分低于对照组,肾上腺素水平高于对照组(P<0.05)。观察组的VAS评分低于对照组,肛门排气及下床活动时间短于对照组(P<0.05)。结论 以患者为中心的护理模式可减轻急诊胆囊切除术患者的生理及心理应激反应,促进患者术后康复。
