Development and validation of the Moral Injury Symptom Scale - Clinician Version - Short Form (MISS-CV-SF).

BACKGROUND: Moral injury occurs when one witnesses or perpetrates an act that transgresses strongly held moral beliefs and expectations. First documented among active military and veterans, moral injury is increasingly studied in healthcare personnel impacted by the coronavirus pandemic. Measurement of moral injury among this population, particularly nurses, is still in its infancy. OBJECTIVE: To develop the Moral Injury Symptom Scale - Clinician-Short Form and validate it among United States based acute care nurses. . METHODS: The Moral Injury Symptom Scale - Military Version was modified for a healthcare audience. 174 acute care nurses responded to a survey package including the scale and related instruments. Reliability and validity, including convergent and discriminant validities, were assessed, and a cutoff score was calculated using the area under the receiver operating characteristic curve. RESULTS: Reliability (Cronbach α = .75) and validity were established and a cutoff score of 41, based on functional impairment caused by moral injury, demonstrated 86.4% sensitivity and 69.6% specificity. Nurses who screened positive for moral injury experienced higher depression, anxiety, work exhaustion, interpersonal disengagement, emotional exhaustion, and depersonalization. . CONCLUSIONS: The Moral Injury Symptom Scale - Clinician Version - Short Form is a valid and reliable instrument with strong psychometric properties that can assess moral injury in acute care nurses, a population at risk due to the challenges of providing care during the pandemic. Appropriate measurement and establishing prevalence should prompt support and intervention from healthcare organizations. .

The effect of a performing arts intervention on caregivers of people with mild to moderately severe dementia.

OBJECTIVES: This study aimed to determine the feasibility and acceptability of a multi-modal performing arts intervention (MPAI) for caregivers of people with mild to moderately severe dementia. The secondary objective was to examine how MPAI might change caregiver burden, caregiver resiliency, and perceived quality of life (QoL) for care recipients. METHOD: The study features a mixed-methods design. Caregivers (N = 32) completed the Zarit Burden Interview (caregiver burden) Brief Resilience Scale (resiliency) and Quality of Life-Alzheimer's disease measure (care recipient QoL) at five study timepoints. Semi-structured interviews (N = 15) documented the intervention's acceptability and caregivers' subjective experiences. Feasibility was indexed through withdrawal and attendance analysis. Braun and Clarke (2006) thematic analysis guided the qualitative analysis. RESULTS: Caregiver burden significantly declined from baseline through final follow-up. Caregiver resiliency and care recipient QoL were not significantly changed but trended up during the intervention until it dropped at the end of the program. Qualitative data suggests the reversal in resiliency and QoL may be explained by caregivers' increased anxiety as the program ended. Acceptability data indicated caregivers were unanimously highly satisfied with the intervention, desiring to continue participation. Feasibility findings provide recommendations for intervention improvements. CONCLUSION: MPAI could reduce caregiver burden and increase resilience for informal caregivers of a person with dementia. Effects drop off quickly at the end of the program, indicating the need for ongoing interventions that provide social support, a respite from the pressures of care recipients' dependency, and the relief that caregivers experience when they perceive benefits to their care recipient's well-being.

Targeted Serum Metabolite Profiling Identifies Metabolic Signatures in Patients with Alzheimer's Disease, Normal Pressure Hydrocephalus and Brain Tumor.

Progression to AD is preceded by elevated levels of 2,4-dihydroxybutanoic acid (2,4-DHB), implicating hypoxia in early pathogenesis. Since hypoxia may play a role in multiple CNS disorders, we investigated serum metabolite profiles across three disorders, AD, Normal Pressure Hydrocephalus (NPH) and brain tumors (BT). Blood samples were collected from 27 NPH and 20 BT patients. The profiles of 21 metabolites were examined. Additionally, data from 37 AD patients and 46 controls from a previous study were analyzed together with the newly acquired data. No differences in 2,4-DHB were found across AD, NPH and BT samples. In the BT group, the fatty acids were increased as compared to HC and NPH groups, while the ketone body 3-hydroxybutyrate was increased as compared to AD. Glutamic acid was increased in AD as compared to the HC group. In the AD group, 3-hydroxybutyrate tended to be decreased with respect to all other groups (mean values -30% or more), but the differences were not statistically significant. Serine was increased in NPH as compared to BT. In conclusion, AD, NPH and BT have different metabolic profiles. This preliminary study may help in identifying the blood based markers that are specific to these three CNS diseases.
