Usability assessment of an intraoperative planning software

Usability is a crucial aspect of medical device safety. The brand-new European Regulation requires the manufacturer to assess the usability of the new medical devices. In this study, we evaluate the usability of a new medical device intended to assist the intraoperative planning with the visualization of 3d patient-specific organ models. The usability study started from the early stage of the device design and iterated through an early formative, completed with desk-based activities, late formative, completed with a focus group, and summative phase, that comprised a user test, and questionnaire filling. The identified usability issues are mitigated, the safety of the device user interface is confirmed and the training contents are defined and confirmed. Additional information regarding the user experience is collected and analyzed to identify further improvements of the device

Italian revised memory and behavior problems checklist (It-RMBPC): validation and psychometric properties in Alzheimer’s disease caregivers

Behavioral and psychiatric symptoms (BPSD), common in persons with Alzheimer’s disease (AD), are known to be associated with caregiver burdening. Therefore, early recognition of BPSD is necessary to protect these caregivers. The aim of this validation study was to test the internal consistency, test–retest reliability and concurrent validity of an Italian translation of the revised memory and behavior problems checklist (RMBPC), as it demonstrated high plasticity in timely measuring the day-to-day BPSD changes that challenge caregivers. A cohort of 355 dyads composed of AD subjects and their principal caregivers were assessed with the Italian version of RMPBC capitalizing on the information provided by the latter ones. The results were compared with the ones from other predictors (i.e., the Zarit Burben Interview, the Hospital Anxiety and Depression Scale, the EurQuality of Life, the neuropsychiatric symptoms). The validity and stability of the It-RMBPC resulted being solid and concurrent reliability resulted having higher correlations with principal caregiver anxiety level. Future studies on the role of BPSD in fostering anxiety in AD principal caregivers are merited

Health related quality of life in adults with repaired tetralogy of Fallot: psychosocial and cognitive outcomes

Objective: To assess the health related quality of life of patients who were operated on during childhood for total correction of tetralogy of Fallot, focusing on the psychosocial and cognitive outcomes. Patients: 54 patients (24 men and 30 women, mean (SD) age 32 (4) years), operated on for total correction of tetralogy of Fallot at mean age of 8.2 years, underwent a cardiological examination, psychological assessment (semistructured interview, Minnesota multiphasic personality inventory), evaluation of quality of life (36 item short form health survey), and neuropsychological assessment with an extensive neuropsychological battery of tests. Results: Psychological characteristics—(1) a lower than normal academic level, (2) a job inadequate for educational level, (3) a preference for an overprotective familiar setting, and (4) a difficulty communicating own corporal image. Denial of the cardiopathy was found to be a common behaviour to normalise functioning. Very few patients had a deficit in memory, learning, or attention functions; rather, patients had a deficit in the executive functions, problem solving, and planning strategies. Conclusions: Despite a satisfactory health related quality of life, there are residual psychological and social problems in addition to impaired cognitive outcomes in the presence of a normal intelligence quotient

Trauma Shaping the Psychopathological Correlates of Patients with Long-COVID: A 6-Months Longitudinal Study with Repeated Measures Mixed Models

: This research aimed at investigating how the experience of trauma can influence the psychological correlates of long-COVID over time in a clinical sample of patients hospitalized because of COVID-19. Through a longitudinal research design, 70 post-acute patients with COVID-19 were followed-up after hospital discharge in 3-time points up to 6 months and completed the Post-traumatic Stress Disorder Checklist for DSM-5 (PCL-5) and the Symptoms Checklist-90-Revised (SCL-90 R). Repeated measures mixed models with random intercept were used to evaluate the effect of trauma (yes/no) over time (T1, T2, T3) on the SCL-90-R scales. Results showed that patients with trauma display significantly worse psychological outcomes in all the SCL-90-R dimensions [all padj < .05 for the principal effects of trauma(y)], especially in symptoms of depression [time 2 vs time 1*trauma(y): b = -3.86, 95%CI (-7.18, -0.53), padj = .035; time 3 vs time 1*trauma(y): b = -4.77, 95%CI (-8.10, -1.45), padj = .011], anxiety [time 3 vs time 1*trauma(y): b = -4.54, 95%CI (-7.72, -1.37), padj = .011], and obsessive-compulsive difficulties [time 3 vs time 1*trauma(y): b = -4.03, 95%CI (-7.20, -0.86), padj = .027]. These findings shed light on the long-term psychological consequences of COVID-19 among hospitalized patients and highlight the key role of trauma, suggesting its assessment to tailor psychological interventions
