The utility of the Pittsburgh Sleep Quality Index in US military personnel

Sleep disturbances are endemic in military personnel with nonclinical populations averaging 6 hours of sleep. The Pittsburgh Sleep Quality Index (PSQI), however, has not been validated in this population. It is thus unknown if the PSQI can differentiate clinically significant sleep disorders from sleep disturbances resulting from military duties with restricted sleep periods. After a clinical evaluation and polysomnogram, participants (N = 148) were classified as having insomnia only, obstructive sleep apnea (OSA) only, comorbid insomnia and OSA (CIO), service-related illnesses only (SRI–; pain, depression, posttraumatic stress disorder, traumatic brain injury), and controls. Military personnel in the insomnia only, and the CIO groups had higher PSQI scores (13.5 ± 2.8 and 14.7 ± 3.5, respectively) compared to the controls (8.9 ± 3.9). A cut-off score of ≥10 was optimal (90% sensitivity and 69% specificity) for determining clinically significant insomnia (≥12 for CIO; 84% sensitivity, 77% specificity). In military personnel, a PSQI score >5 is not necessarily indicative of a clinically significant sleep disorder. The use of elevated cut-off PSQI scores are likely better suited to differentiate military personnel who require further clinical evaluation versus a more conservative sleep improvement protocol.     

Connecting Past with Present: A Mixed-Methods Science Ethics Course and its Evaluation

We present a graduate science ethics course that connects cases from the historical record to present realities and practices in the areas of social responsibility, authorship, and human/animal experimentation. This content is delivered with mixed methods, including films, debates, blogging, and practicum; even the instructional team is mixed, including a historian of science and a research scientist. What really unites all of the course’s components is the experiential aspect: from acting in historical debates to participating in the current scientific enterprise. The course aims to change the students’ culture into one deeply devoted to the science ethics cause. To measure the sought after cultural change, we developed and validated a relevant questionnaire. Results of this questionnaire from students who took the course, demonstrate that the course had the intended effect on them. Furthermore, results of this questionnaire from controls indicate the need for cultural change in that cohort. All these quantitative results are reinforced by qualitative outcomes.     

Anxiety and depression in cataract surgery: a pilot study in the elderly

To assess anxiety induced by a planned cataract surgery and to evaluate the correlations of rated anxiety and depression with optical acuity pre- and post-operatively, 278 patients ages 65 years or older were tested. Patients were divided into two groups: first-eye and second-eye cataract surgery. Anxiety and depression were evaluated using the Hamilton's Rating Scales for Anxiety and Depression, respectively. Pre-operatively, first-eye patients showed significantly higher anxiety than second-eye patients (F1,251 = 75.39, p < .001). First-eye patients rated peak anxiety on the day of the surgery, while patients scheduled for second-eye cataract surgery presented no fluctuations in rated anxiety (F1,251 = 49.60, p < .001). There was no correlation of preoperative anxiety or depression with the outcome of surgery (F(1,251)s = .83 and .58, respectively, p > .05). Postoperatively, anxiety and depression in patients without any improvement in their vision were rated significantly higher than in those presenting improved visual acuity after surgery (F1,251 = 566.17 and 300.25, respectively, p < .001).     

Assessing quality of care and observance of human rights in residential mental health facilities in Greece through the WHO QualityRights tool kit

In this paper, we present and reflect upon the process of evaluating two residential mental health facilities in Thessaloniki, Greece, through the WHO QualityRights tool kit. The QualityRights tool kit is a structured process for assessing quality of care and human rights in mental health and social care facilities, in accordance with the United Nations Convention on the Rights of Persons with Disabilities (CRPD), introduced by the World Health Organization in 2012. We have piloted the use of the Toolkit in two supported accommodation facilities, a hostel and a service supervising independent living in apartments, for individuals with long-term severe mental health problems in the region of Thessaloniki. In this paper, we present the methodology and process of evaluating the facilities, including the challenges posed to the evaluation process by restrictions due to the Covid-19 pandemic. We showcase the outcome of this evaluation through presenting a summary of the results and the ensuing recommendations for improvement. Finally, we reflect on the usefulness, appropriateness and relevance of the Toolkit for evaluating mental health care facilities in the particular context of contemporary Greece.     

Development of a Robust Multicriteria Classification Model for Monitoring the Postoperative Behaviour of Heart Patients

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia occurring in 2% of the general population, while the assuming projected incidence in 2050 will rise to 4.3%. This paper presents a multicriteria methodology for the development of a model for monitoring the post‐operative behaviour of patients who have received treatment for AF. The model classifies the patients in seven categories according to their relapse risk, on the basis of seven criteria related to the AF type and pathology conditions, the treatment received by the patients and their medical history. The analysis is based on an extension of the UTilités Additives DIScriminantes (UTADIS) method, through the introduction of a two‐stage model development procedure that minimizes the number and the magnitude of the misclassifications. The analysis is based on a sample of 116 patients who had pulmonary veins isolation in a Greek public hospital. The classification accuracy of the best fitted models scores between 71% and 84%.

The Greek Version of the Difficulties in Emotion Regulation Scale: Testing the Factor Structure, Reliability and Validity in an Adult Community Sample

We examined the factor structure, reliability, convergent and criterion validity of the Greek version of the Difficulties in Emotion Regulation Scale (DERS) using data from a community lifespan sample. Exploratory and confirmatory factor analyses revealed a clear six-factor structure consistent with the factor structure evidenced in English-speaking samples. The results also demonstrated adequate classical psychometric properties in terms of internal consistency and test-retest reliability. The scale branches demonstrated convergent and concurrent validity with personality, emotion intelligence abilities and coping strategies. The importance of using culturally validated dimensional measures of emotion regulation is discussed.     

Early signs of memory impairment among multiple sclerosis patients with clinically isolated syndrome

The study investigates primary and secondary verbal memory and motor/executive functions (response inhibition and strategy shifting ability) in multiple sclerosis (MS) patients with clinically isolated syndrome (CIS). We studied 44 CIS patients and compared them to 49 patients with relapsing remitting MS (RR-MS) displaying mild disability and to a large cohort of age- and education level-matched healthy volunteers(n=230). Results showed that both CIS and RR-MS patients evidenced a disproportionate impairment in the immediate and delayed recall of the second (as compared to the first) of two short narratives of the Logical Memory WMS-III subtest, and reduced performance on the Memory for Digits-Forward. Performance of either group on the executive tasks was not impaired, showing evidence of a reversed speed-accuracy trade-off. Illness duration emerged as a significant predictor of memory and executive task performance. Clinical, psychoemotional, and brain imaging findings were also examined as potential correlates of memory deficits and disease progression among CIS patients. These findings may signify early-onset decline of specific cognitive functions in CIS, which merits regular follow-up assessments and monitoring of psychoemotional adaptation and everyday functioning.
