基于罗森塔尔效应的护理干预对脑出血后遗症病人的心理状况和生活质量的影响

目的:探讨基于罗森塔尔效应的护理干预对脑出血后遗症病人的心理状况和生活质量的影响。方法:按照随机数字表法将2019年1月—2021年1月收治的98例脑出血后遗症病人分为对照组和观察组各49例,对照组实施常规护理,观察组在常规护理基础上给予基于罗森塔尔效应的护理干预。干预前后采用卒中量表(NIHSS)、功能独立性评定量表(FIM)、生活活动功能测量量表Barthel指数(BADL)评定两组病人康复情况,采用非精神病性焦虑量表(HADS-A)、非精神病性抑郁量表(HADS-D)、自我效能量表(GSES)评定两组病人心理状态,采用生活质量简明调查表(SF-36)评定两组病人生活质量。结果:观察组病人干预后NIHSS评分低于对照组,FIM和BADL评分高于对照组(P<0.05);观察组病人干预后HADS-A和HADS-D评分低于对照组,GSES评分高于对照组(P<0.05);观察组病人干预后生活质量各维度(躯体功能、躯体角色、肌体疼痛、总体健康、活力、社会功能、情绪角色、心理卫生)评分均明显高于对照组(P<0.05)。结论:基于罗森塔尔效应的护理干预应用于脑出血后遗症病人能有效促进病人康复,改善病人心理状态,提高病人生活质量。     

Levels and variables associated with psychological distress during confinement due to the coronavirus pandemic in a community sample of Spanish adults

Due to the COVID-19 pandemic's consequences and the state of alarm, literature has shown that people worldwide have experienced severe stressors that have been associated with increased prevalence of emotional distress. In this study, we explored psychological distress (depression, anxiety, and somatization symptoms) using an online survey platform in a sample of 1,781 Spanish adults during the confinement due to COVID-19, relationships between distress and sleep problems, affect, pain, sleep, emotional regulation, gender, type of housing, history of psychopathology, and living alone during the confinement, and differences depending on demographic and psychological variables. Results showed that between 25% and 39% of the sample referred to clinically significant levels of distress. In addition, women showed higher levels of distress, negative affect, perception of pain, and cognitive reappraisal and lower levels of emotional suppression and sleep quality than men. A history of psychopathology, being younger, living alone or in a flat was associated with higher distress. Finally, the variables most strongly related to distress were negative and positive affect, levels of pain, sleep quality, and emotional suppression. Our results highlight the important role of emotional suppression, cognitive reappraisal, and loneliness and the impact of being a woman and younger in Spain during the COVID-19 pandemic. Therefore, it would be necessary to provide assessments of distress levels in these population groups and focus psychological preventive and therapeutic online interventions on expressing emotions and preventing loneliness.     

Novel variants in aromatic L-amino acid decarboxylase deficiency: Case report of sisters with mild phenotype

BackgroundAromatic L-amino acid decarboxylase (AADC) deficiency, caused by a pathogenic variant in the dopa decarboxylase (DDC) gene, is a rare neurometabolic disorder in which catecholamine and serotonin are not synthesized. From a large number of reports, it has been recognized that most affected patients show severe developmental delay in a bedridden state and are unable to speak. On the other hand, patients with a mild phenotype with AADC deficiency have been reported, but they number only a few cases. Therefore, the variation of phenotypes of the disease appears to be broad, and it may be challenging to diagnose an atypical phenotype as AADC deficiency.Case reportWe report novel compound heterozygous variants in DDC (c.202G > A and c.254C > T) in two sisters, whose main complaint was mild developmental delay, by whole-exome sequencing (WES). Additionally, we describe their clinical features and provide an image that shows the variants located at different sites responsible for the catalysis of AADC in a three-dimensional structure. The patients were prescribed a Monoamine oxidase (MAO) inhibitor after diagnosis.InterpretationOur cases indicate that a comprehensive genomic approach helps to diagnose AADC deficiency with atypical features, and underscore the significance of understanding the variations of this disorder for diagnosis and appropriate treatment.     

Advanced Cancer Patients' Prognostic Awareness and Its Association With Anxiety,Depression and Spiritual Well-Being: A Multi-Country Study in Asia

AimsThe associations between prognostic awareness, acceptance of illness and psychological outcomes (anxiety, depression and spiritual well-being) remain unclear. This study examined the associations between prognostic awareness and various psychological outcomes and how they can be moderated by patient acceptance of illness (cancer).Materials and methodsIn total, 1184 patients with stage IV solid cancer were recruited at major public hospitals across four Asian countries (China, India, Sri Lanka, Vietnam). Prognostic awareness and acceptance of illness were assessed through self-reported understanding of treatment intent and acceptance of illness, respectively. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale, whereas spiritual well-being was measured using the Functional Assessment of Chronic Illness Therapy – Spiritual Well-Being Scale. Multivariate regressions were used to estimate the associations while controlling for patient characteristics.ResultsCompared with being unaware of their prognosis (i.e. believing that their cancer is curable), being aware or unsure of their prognosis was associated with higher anxiety and depressive symptoms, and lower spiritual well-being scores. Acceptance of illness moderated these relationships and improved the psychological outcomes.ConclusionsThe results suggest that disclosure of prognostic information should be provided in conjunction with psychological interventions that focus on acceptance of illness.     

护士心理安全感在组织支持感与敬业度的中介作用

目的探讨护士组织支持感、心理安全感与敬业度的关系,为提升护士敬业度及改善护理管理提供依据。方法采用一般资料调查表、组织支持感量表、心理安全感量表及盖洛普Q12调查表对天津市3所三级甲等医院的414名护士进行问卷调查。结果护士敬业度总均分为(2.09±0.38)分,处于中等水平,组织支持感总均分为(3.19±0.31)分,心理安全感总均分为(3.42±0.45)分。护士敬业度、组织支持感、心理安全感三者呈正相关(P0.05,P0.01),心理安全感在组织支持感与敬业度的关系中发挥部分中介作用,中介效应为0.34,心理安全感与组织支持感共同解释敬业度总变异的21%。结论护士敬业度处于中等水平,护理管理者应创造良好的组织支持环境,给予护士更多情感支持以提高护士的心理安全感,从而提高其敬业度。     

Effect of cholinergic crisis on the potency of different emergency anaesthesia protocols in soman-poisoned rats

Background: In a military or terrorist scenario, combination of organophosphorus compounds (OP) poisoning with physical trauma requiring surgical treatment and thus general anaesthesia are possible. Previous in vitro studies showed an altered potency of relevant anaesthetics during cholinergic crisis. Hence, it is not clear, which anaesthetics are suitable to achieve the necessary stage of surgical anaesthesia in OP poisoning.

Methods: In the present study, different anaesthetic regimens (ketamine-midazolam, propofol-fentanyl, thiopental-fentanyl), relevant in military emergency medicine, were examined in soman-poisoned rats. Clinical signs and cardiovascular variables were recorded continuously. Blood samples for acetylcholinesterase (AChE) activity were drawn. After euthanasia or death of the animals, brain and diaphragm were collected for cholinesterase assays.

Results: Propofol-fentanyl and thiopental-fentanyl resulted in surgical anaesthesia throughout the experiments. With ketamine-midazolam, surgical anaesthesia without respiratory impairment could not be achieved in pilot experiments (no soman challenge) and was therefore not included in the study. Soman-poisoned and control animals required a comparable amount of propofol-fentanyl or thiopental-fentanyl. In combination with atropine, significantly less propofol was needed. Survival rate was higher with thiopental compared to propofol. Atropine improved survival in both groups. Blood and tissue AChE activities were strongly inhibited after soman administration with and without atropine treatment.

Discussion: The current in vivo study did not confirm concerns of altered potency of existing anaesthetic protocols for the application of propofol or thiopental with fentanyl due to soman poisoning. Despite severe cholinergic crisis, sufficient anaesthetic depth could be achieved in all animals.

Conclusion: Further experiments in in vivo models closer to human pharmaco- and toxicokinetics (e.g., swine) are required for confirmation of the initial findings and for improving extrapolation to humans.
