Background Due to the 2019 novel coronavirus (COVID-19) disease outbreak, social distancing measures were imposed to control the spread of the pandemic. However, isolation may affect negatively the psychological well-being and impair sleep quality. Our aim was to evaluate the sleep quality of respiratory patients during the COVID-19 pandemic lockdown. Methods All patients who underwent a telemedicine appointment from March 30 to April 30 of 2020 were asked to participate in the survey. Sleep difficulties were measured using Jenkins Sleep Scale. Results The study population consisted of 365 patients (mean age 63.9 years, 55.6% male, 50.1% with sleep-disordered breathing [SDB]). During the lockdown, 78.9% of participants were confined at home without working. Most patients (69.6%) reported at least one sleep difficulty and frequent awakenings was the most prevalent problem. Reporting at least one sleep difficulty was associated with home confinement without working, female gender and diagnosed or suspected SDB, after adjustment for cohabitation status and use of anxiolytics. Home confinement without working was associated with difficulties falling asleep and waking up too early in the morning. Older age was a protective factor for difficulties falling asleep, waking up too early and non-restorative sleep. Notably, SDB patients with good compliance to positive airway pressure therapy were less likely to report sleep difficulties. Conclusions Home confinement without working, female gender and SDB may predict a higher risk of reporting sleep difficulties. Medical support during major disasters should be strengthened and potentially delivered through telemedicine, as this comprehensive approach could reduce psychological distress and improve sleep quality.

In this paper we searched for vertebral deformities in a group of 70 premenopausal systemic lupus erythematosus (SLE) patients (31.8 +/- 8.1 years old) and compared them to a matched control group of 22 healthy women (32.0 +/- 8.9 years old). Patients and controls performed spine X-ray (XR) morphometry and lumbar spine and femoral neck bone mineral density (BMD). Clinical data was obtained by a questionnaire and charts review. Thoracic or lumbar spine fracture was observed in 15 (21.4%) SLE patients, while no deformities were found in the control group (P = 0.018). BMD was not different amongst SLE patients and controls and between SLE patients with or without deformities. Although BMD could not predict what patient have deformity, seven patients (46.6%) with deformity had a lumbar spine or femoral neck Z-score less than - 1 SD [median = -0.59 (-3.72 to +0.88) and -0.20 (-4.05 to + 1.87)] respectively. In addition, we found a negative correlation between number of fracture per patient and lumbar spine and femoral neck BMD (R = 0.58, P = 0.04 and R = 0.84, P = <0.0001 respectively). No significant correlation was found between number of deformities and clinical data. This is the first study to search for vertebral deformities in SLE patients and to demonstrate a high prevalence of deformities in a relative young SLE population. These findings bring up the necessity to look for spine deformities in this group of women regardless the BMD.

Our results show differences in the respiratory patterns of healthy adults and the elderly, suggesting that age impacts on lung function. Both male and female elderly subjects had lower lung function testing scores than the adult subjects, with this difference more marked in females.
