移植协调员在DCD工作中的角色和作用

器官捐献是器官移植事业发展的基石,而协调员在器官捐献工作中则有着举足轻重的地位和作用。自2010年3月我国推行人体器官捐献试点工作以来,适合中国国情的DCD工作成为器官捐献工作的重中之重。如何充分发挥协调员在DCD工作中的作用,提高DCD捐献率和供体转化率,以有效地促进和推动DCD工作,是急待探讨和解决的问题。本文结合...     

Resting EEG in alpha and beta bands predicts individual differences in attentional blink magnitude

Accuracy for a second target (T2) is reduced when it is presented within 500 ms of a first target (T1) in a rapid serial visual presentation (RSVP) - an attentional blink (AB). There are reliable individual differences in the magnitude of the AB. Recent evidence has shown that the attentional approach that an individual typically adopts during a task or in anticipation of a task, as indicated by various measures, predicts individual differences in the AB deficit. It has yet to be observed whether indices of attentional approach when not engaged in a goal-directed task are also relevant to individual differences in the AB. The current studies investigated individual differences in the AB by examining their relationship with attention at rest using quantitative measures of EEG. Greater levels of alpha at rest were associated with larger AB magnitudes, where greater levels of beta at rest were associated with smaller AB magnitudes. Furthermore, individuals with more beta than alpha demonstrated a smaller AB effect than individuals with more alpha than beta. Our results suggest that greater attentional engagement at rest, when not engaged in a goal-directed task, is associated with smaller AB magnitudes.     

Contamination transfusionnelle et relations sexuelles non protégées : les limites du droit à indemnisation du transfusé au titre de la solidarité nationale (Civ., 1re, 22 janvier 2014, no 12-35023, FS P+B+I)

A patient victim of HIV infection by transfusion who knowingly maintained sexual relation with his spouse cannot receive compensation for moral prejudice in the case of his spouse and daughter's contamination. The request for compensation addressed to the ONIAM on the grounds of the articles L. 1142-22 and L. 3122-1 of the Public Health Code must therefore be rejected.     

IQ and Scores on the Mini-Mental State Examination (MMSE): Controlling for Effort and Education Among Geriatric Inpatients

ABSTRACT

The Mini-Mental State Examination (MMSE) and the Peabody Picture Vocabulary Test, Third Edition (PPVT-III) were administered to 76 Extended Care Center inpatients of a Veterans Affairs Medical Center, 56 of whom did not carry a diagnosis associated with brain impairment, and 20 of whom had a diagnosis associated with degenerative or cerebrovascular conditions. MMSE and PPVT-III scores, the latter of which estimates verbal IQ, were significantly correlated in both groups, even when controlling for the effects of education. This correlation was attenuated, but remained significant, in the face of varying levels of patient effort. The findings of this study support earlier findings, which also suggest that interpretation of “impaired” performance on the MMSE for those with IQ scores below 90 should be interpreted with caution. Average MMSE scores for Wechsler IQ classifications are provided.     

Examining the Potential Exploitation of UNOS Policies

The United Network for Organ Sharing (UNOS) waiting list was designed as a just and equitable system through which the limited number of organs is allocated to the millions of Americans in need of a transplant. People have trusted the system because of the belief that everyone on the list has an equal opportunity to receive an organ and also that allocation is blind to matters of financial standing, celebrity or political power. Recent events have revealed that certain practices and policies have the potential to be exploited. The policies addressed in this paper enable those on the list with the proper resources to gain an advantage over other less fortunate members, creating a system that benefits not the individual most in medical need, but the one with the best resources. These policies are not only unethical but threaten the balance and success of the entire UNOS system. This paper proposes one possible solution, which seeks to balance the concepts of justice and utility.

     

Death anxiety,altruism, self‐efficacy,and organ donation intention among Japanese college students: A moderated mediation analysis

The shortage of organs for transplantation in Japan has alerted health professionals to the low organ donation rate among Japanese people. The unique cultural view of death and altruism has been suggested leading to their low intent to donate cadaveric organs. A cross‐sectional survey was conducted in Japan to investigate the interplay of death anxiety, altruism, and self‐efficacy in influencing Japanese college students' intention to sign donor cards, in order to mobilise this large potential source of organ donors in the future. Six hundred and seven Japanese non‐donor card signers voluntarily completed a self‐administered questionnaire. The results of mediation and moderated mediation analyses with bootstrap approach suggest that death anxiety indirectly hinders Japanese people's intention to become a donor card signer through lowering of self‐efficacy, while altruism intensifies the positive impact of self‐efficacy on signing intention. These findings provide useful insights for organ procurement organisations seeking behavioural change not only in Japan but also in multi‐ethnic societies with a substantial Japanese population.     

First-Trial Adaptation to Prism Exposure

Terminal target-pointing error on the 1st trial of exposure to optical displacement is usually less than that expected from the optical displacement magnitude. Such 1st trial adaptation was confirmed in 2 experiments (N = 48 students in each) comparing pointing toward optically displaced targets and toward equivalent physically displaced targets (no optical displacement), with visual feedback delayed until movement completion. First-trial performance could not be explained by ordinary target undershoot, online correction, or reverse optic flow information about true target position and was unrelated to realignment aftereffects. Such adaptation might be an artifact of the asymmetry of the structured visual field produced by optical displacement, which induces a felt head rotation opposite to the direction of the displacement, thereby reducing the effective optical displacement.     

Impact of organ transplantation in heart,lung and liver recipients: Assessment of positive life changes

Objective: The majority of psychological studies with organ transplant recipients have examined negative psychological effects. This study aimed to further investigate the positive effects of organ transplantation and to construct a specific measurement instrument.

Design: The initial pool of 14 items for the Positive Effects of Transplant Scale (PETS) was derived from organ recipient interviews. A cross-sectional postal study included 87 heart, 46 lung and 193 liver transplant recipients. The PETS was subjected to principal components analysis (PCA) using varimax rotation, and associations with other measures investigated.

Main outcome measures: PETS and an open-ended item about positive effects.

Results: Coding of the open-ended item revealed that the majority of recipients attributed positive life changes to the transplant experience. PCA of the PETS indicated three factors that accounted for 58.82% of the variance. The 12-item questionnaire assesses improvements in: (1) life philosophy, (2) gratitude and (3) health. The total PETS scores exhibited adequate internal consistency and validity.

Discussion: Most transplant patients report positive psychological effects, which suggests this may be an understudied area. The initial development of an assessment tool provides researchers and clinicians a way to assess the degree and nature of these life changes.
