ABSTRACT
OBJECTIVE: Psychosocial parameters play a pivotal role in organ recipient evaluation before wait-listing for transplantation because of their impact on organ and patient outcome. Patients in need of heart (HTx), liver (LTx), or kidney transplantation (KTx) face distinct physical and psychological challenges. This study compares the psychosocial characteristics and preferences for additional therapy for patients undergoing assessment for these three types of organ transplantation to optimize patient-tailored psychological, social, and other supportive interventions. METHODS: We conducted a cross-sectional, observational study with 1110 potential transplantation candidates (LTx, n = 544; KTx, n = 330; HTx, n = 236), psychosocial status was determined for depressive symptoms (Patient Health Questionnaire Depression Scale), anxiety symptoms (seven-item Generalized Anxiety Disorder Screener), health-related quality of life (36-Item Short Form Health Survey), perceived social support (Perceived Social Support Questionnaire), sense of coherence (SoC; short form of the Sense of Coherence Scale), self-efficacy (General Self-Efficacy Short Scale), and body image (German Body Image Questionnaire-20). Preferences for additional supportive therapy were assessed dichotomously. Data were analyzed using multivariate analysis of covariance and χ2 tests. RESULTS: Patient groups differed significantly regarding depression ( F (2,1107) = 35.283, p < .001, partial η2 = 0.01), anxiety ( F (2,1107) = 15.027, p < .001, partial η2 = 0.03), health-related quality of life (physical: F (2,1107) = 96.772, p < .001, partial η2 = 0.15; mental: F (2,1107) = 11.442, p < .001, partial η2 = 0.02), perceived social support ( F (2,1107) = 20.813, p < .001, partial η2 = 0.04), SoC ( F (2,1107) = 12.920, p < .001, partial η2 = 0.02), self-efficacy ( F (2,1107) = 17.308, p < .001, partial η2 = 0.03), and body image (rejecting body evaluation: F (2,1107) = 5.006, p = .007, partial η2 = 0.01; vital body dynamics: F (2,1107) = 40.216, p < .001, partial η2 = 0.07). Patients evaluated for HTx showed the highest psychosocial impairment and the highest inclination regarding additional supportive therapy. CONCLUSIONS: Patients evaluated for HTx, LTx, and KTx have distinct psychosocial characteristics and treatment preferences. HTx patients display the highest psychosocial impairment. We suggest psychocardiological treatment structures for optimal outcome.

Several questions concerning the survival of isolated neurons and neuronal stem and progenitor cells (NPCs) have not been answered in the past: (1) If lactate is discussed as a major physiological substrate of neurons, do neurons and NPCs survive in a glucose-free lactate environment? (2) If elevated levels of glucose are detrimental to neuronal survival during ischemia, do high concentrations of glucose (up to 40 mmol/L) damage neurons and NPCs? (3) Which is the detrimental factor in oxygen glucose deprivation (OGD), lack of oxygen, lack of glucose, or the combination of both? Therefore, in the present study, we exposed rat cortical neurons and NPCs to different concentrations of D: -glucose ranging from 0 to 40 mmol/L, or 10 and 20 mmol/L L-lactate under normoxic and anoxic conditions, as well as in OGD. After 24 h, we measured cellular viability by biochemical assays and automated cytochemical morphometry, pH values, bicarbonate, lactate and glucose concentrations in the cell culture media, and caspases activities. We found that (1) neurons and NPCs survived in a glucose-free lactate environment at least up to 24 h, (2) high glucose concentrations >5 mmol/L had no effect on cell viability, and (3) cell viability was reduced in normoxic glucose deprivation to 50% compared to 10 mmol/L glucose, whereas cell viability in OGD did not differ from that in anoxia with lactate which reduced cell viability to 30%. Total caspases activities were increased in the anoxic glucose groups only. Our data indicate that (1) neurons and NPCs can survive with lactate as exclusive metabolic substrate, (2) the viability of isolated neurons and NPCs is not impaired by high glucose concentrations during normoxia or anoxia, and (3) in OGD, low glucose concentrations, but not low oxygen levels are detrimental for neurons and NPCs.

BACKGROUND: Wilson disease is an autosomal recessive disorder of copper metabolism and requires lifelong medical treatment. Therefore, the analysis of quality of life has gathered more attention. Aims of this study were to examine risk for depression and health-related quality of life in patients suffering from Wilson disease. METHODS: Sixty-eight patients were included in this retrospective cross sectional study. The Personal Health Questionnaire-9 Depression Scale was used to assess depression. The Short Form-36 Health Survey questionnaire was used to assess health-related quality of life. RESULTS: The Personal Health Questionnaire-9 indicated that 21% (14/68) of patients were at risk for major depressive disorders (scores>10) and 35% (24/68) were at risk for mild depression (scores 5-9). Women had significantly lower life quality scores than men. Primary neurologic disease manifestation was associated with significantly lower total Short Form-36 and subdimension scores compared with primary hepatic or mixed presentation. Overall, patients with Wilson disease experienced higher quality of life than patients with other chronic liver diseases. CONCLUSIONS: As patients with Wilson disease have a high risk for depressive disorders, active assessment for depression is mandatory. Patients with primary neurological symptoms are at higher risk for reduction of life quality.
