医学伦理学与生命伦理学关系类型辨析——基于国内外文献的考察

医学伦理学与生命伦理学的关系在逻辑上有包容论、互异论和交叉论（延续论）三种可能的类型。包容论认为,后者关注范围更广,前者作为一个部分包括在生命伦理学当中。互异论主张,两个概念在跨学科特点方面不同,生命伦理学必须通过跨学科协作,以公共性为导向,而医学伦理学较为单一,以职业性为目标。交叉论（延续论）强调,医学伦理学经历了古代医德学,近现代医学伦理学和生命伦理学。包容论与互异论过于强调二者的相同或区别,割裂了二者内在联系,片面性显而易见。交叉论（延续论）看到了二者内在逻辑,反映了本体属性,是更为合理的评价。     

直觉思维在麻醉临床决策中的应用

围手术期麻醉医师面临问题的复杂性、动态性和模糊性,要求其在具备良好逻辑思维能力的同时,还要学会应用直觉思维来进行麻醉危机管理。通过决策判断的双加工理论模型探讨说明直觉思维在临床麻醉决策中的可应用性,并给出麻醉医师直觉思维的培养途径,提高麻醉医师的思考能力,增加应急处理课程和临床训练,重视临床经验的学习,营造良好的教学氛围。为了在围手术期更好地保证患者的安全,麻醉医师应重视直觉思维在临床麻醉决策中的应用。

The Suicidal Narrative and Its Relationship to the Suicide Crisis Syndrome and Recent Suicidal Behavior

In this study, we introduce the construct of the suicidal narrative, a hypothetical personal narrative linked to imminent suicide, and explore its relationship to near‐term suicidal risk and the suicide crisis syndrome (SCS). Psychiatric outpatients (N = 289) were administered the Columbia Suicide‐Severity Rating Scale (C‐SSRS), Suicide Crisis Inventory (SCI), and Suicide Narrative Inventory (SNI), a novel instrument combining the documented risk factors of Thwarted Belongingness, Perceived Burdensomeness, Humiliation, Social Defeat, Goal Disengagement, and Goal Reengagement. Dimensional measures of past month, lifetime, and past suicidal phenomena, incorporating ideation and behavior, were calculated from the C‐SSRS. Structural equation modeling was used to explore the interaction among variables. Factor analysis of the SNI yielded two orthogonal factors, termed Interpersonal and Goal Orientation. The former factor was comprised of Perceived Burdensomeness, Social Defeat, Humiliation, and Thwarted Belongingness, the latter of Goal Disengagement and Goal Reengagement. The Interpersonal factor correlated with both SCS severity and suicidal phenomena in each time frame and the Goal Orientation factor with no other variable. As hypothesized, the proposed model was significant for the past month only. Our findings support the construct of the suicidal narrative and its function as a near‐term suicidal risk factor.     

患者和家属参与患者安全的概念演变及临床意义

运用Rodgers演化概念分析法对患者和家属参与患者安全概念的演化、替代术语和相关术语、前因变量、结果、概念属性、定义、典型案例进行分析。概念属性包含过程、行为及环境3个领域,4个重要特征分别为个性化、获取、投入及治疗联盟,其前因变量为患者的疾病、健康信息或护理协调的混乱、新政策号召的尝试。结果包括保障患者安全、减少医疗费用和确定最佳做法。澄清患者和家属参与患者安全的概念有助于提高医护人员对其的重视与了解,为临床的实践和研究提供参考和理论依据。

     

Comparisons of the Interpersonal–Psychological Theory of Suicide Constructs Among Individuals Without Suicidality,Ideators, Planners,and Attempters

The Interpersonal–Psychological Theory of Suicide (IPTS) proposes that combinations of thwarted belongingness, perceived burdensomeness, and acquired capability lead to suicide ideation, planning, and attempting. We compared individuals with and without suicidality on thwarted belongingness and perceived burdensomeness, and compared a combined group of planners and attempters to ideators on fearlessness about death (one component of acquired capability). Individuals with suicidality had higher thwarted belongingness and perceived burdensomeness than individuals without suicidality. Planners and attempters did not have higher fearlessness about death than ideators. These findings partially support IPTS hypotheses. Assessing thwarted belongingness and perceived burdensomeness may improve suicide risk determination.     

Connecting Eating Pathology with Risk for Engaging in Suicidal Behavior: The Mediating Role of Experiential Avoidance

Individuals with eating pathology, particularly those with diagnosed eating disorders, are at high risk for suicide. It is less clear whether undiagnosed eating pathology and subsyndromal eating disorders carry the same risk and, if so, what mechanisms may explain why higher levels of eating pathology yield greater risk for engaging in suicidal behaviors. The indirect relationship between disordered eating and risk for suicidal behaviors via facets of experiential avoidance was tested using a multiple‐mediator model. The model was tested using bootstrapping estimates of indirect effects in a sample of 218 noncollege student adults (Mage = 32.33, 66.1% women) with a history of suicidal attempt and/or history of nonsuicidal self‐injury (NSSI). Results revealed that disordered eating indirectly predicted risk for suicidal behaviors, distress aversion (i.e., negative attitudes or dislike of distress), and procrastination (i.e., delaying engagement with distressing activities). Results suggest that targeting experiential avoidance and helping those who have a history of engaging in suicidal behaviors and/or NSSI develop regulation strategies to use during times of distress may be of utmost importance for treatment and prevention of eating pathology.     

The Quadratic Relationship Between Body Mass Index and Suicide Ideation: A Nonlinear Analysis of Indirect Effects

A nonlinear indirect effects framework was used to investigate potential interpersonal indirect effects (i.e., perceived burden and thwarted belonging) accounting for the nonlinear relationship between body mass index (BMI) and suicide ideation. Using a sample of 338 undergraduates, results revealed a significant quadratic effect of BMI on suicide ideation via perceived burden only, which became significant as BMI fell below 18.00 kg/m² and above 28.00 kg/m². Our results provide novel information relevant for suicide risk screening in the context of weight‐ and health‐related interventions and provide justification for future longitudinal trials assessing suicide risk across the BMI spectrum.
