This pilot study pretends to evaluate the accuracy of Fitbit Flex®, a consumer device for diary register, for the evaluation of sleep quality, compared to Actigraph GR3X, one of the most recommended actigraphs for sleep evaluation. To achieve this, sixty seven subjects without sleep disorders used simultaneously both monitors, Fitbit Flex® and Actigraph GT3X®, during one week nights. Even the significative differences between both monitors, de high correlation values and the ICC suggest that Fitbit Flex commercial device could be a useful instrument for the sleep quality evaluation, assuming that this result can not be considered interchangeable with Actigraph GR3X.

Abstract Introduction COVID-19 epidemic led to great psychological and social stress, related to anxiety, depression, sleep disorders, suicidal risk and behavior, and changes in daily routine. The aim of this study was to assess the psychological impact of COVID-19 lockdown in Italian students. We focused on perceived sleep quality, anxiety and depression symptoms, and mostly on risk of suicide. Methods A total of 307 students (mean age 22.84±2.68) completed Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), Beck Anxiety Inventory (BAI), and Beck Depression Inventory-II (BDI-II). In our study, we focused on item 9 of BDI-II, that is related to suicide. We divided our sample on presence or absence of suicidal ideation based on this item. Results We found that 30.1% showed depressive, while 38.2% anxious symptoms. Concerning item 9 of BDI-II (suicidal thoughts or wishes), 84.7% answered that they do not have any thoughts of killing themselves, while 15.3% answered that they have some suicidal ideation. Concerning sleep variables, we found that 58% of our sample showed a PSQI total score higher than 5 (poor quality of sleep), and a global worsening in sleep quality and increase of insomnia both in student with and without suicidal ideation. Conclusion Our results on risk of suicide are in line with literature. Recent reviews focused on suicidal ideation in medical students found that depressive symptoms and suicidal ideation are common among medical students, finding a prevalence of suicidal ideation of 11%. Several studies suggest that sleep disorders are a risk factor for suicidal thoughts and behaviours. Our findings show that sleep cannot considered a predictive factor of risk of suicide during health emergency, because the risk is polyfactorial. Support (if any) None

Abstract Background During the COVID-19 pandemic, individuals faced psychological stress caused by fear and anxiety due to the high transmission and mortality rate of the disease, the social isolation, economic problems, and difficulties in reaching health services. Fibromyalgia (FM) is a chronic centralized pain sensitivity disorder. Psychological, physical and/or autoimmune stressors were found to increase FM symptoms. This pilot study aimed to evaluate the COVID-19 fear and anxiety level, and to examine their effect on disease severity, sleep quality, and mood in FM patients compared to control group. Methods This pilot study conducted as a cross-sectional study, and included 62 participants. Participants were divided into two groups: FM patient group (n = 31) and control group (n = 31). Symptom severity, sleep quality, and mood were determined using the Revised Fibromyalgia Impact Questionnaire (FIQR), Pitsburg Sleep Quality Index (PSQI), and Hospital Anxiety Depression Scale (HADS), respectively. In order to evaluate the level of COVID-19 fear and anxiety, the Fear of COVID-19 Scale (FCV-19S) and Coronavirus Anxiety Scale (CAS) were used compared to control group. Results FIQR, PSQI, HAD-A, HAD-D, FCV-19S and CAS scores were significantly higher in the FM group (p = 0.01). A positive significant correlation was found between FCV-19S and CAS results and FIQR, PSQI, and HAD-anx results in FM patients (p < 0.05). Conclusion This pilot study showed that, the individuals with FM can be more affected by psychological stress, and this situation negatively affects the symptom severity, sleep quality, and mood in FM patients, so these patients should be closely monitored in terms of psychological stressors and their effects during pandemics. More studies with more participants are necessary to describe the challenges lived by fibromyalgia population.
