Reduced Sleep Duration and Sleep Efficiency Were Independently Associated With Frequent Nightmares in Chinese Frontline Medical Workers During the Coronavirus Disease 2019 Outbreak.

OBJECTIVES: Nightmares were related to emotion and behavioral problems and also emerged as one of the core features of post-traumatic stress disorder (PTSD). Our study aimed to investigate the associations of frequent nightmares with sleep duration and sleep efficiency among frontline medical workers in Wuhan during the coronavirus disease 2019 (COVID-19) outbreak. METHODS: A total of 528 health-care workers from the province of Fujian providing medical aid in Wuhan completed the online questionnaires. There were 114 doctors and 414 nurses. The age, sex, marital status, and work situation were recorded. A battery of scales including the Pittsburgh Sleep Quality Index (PSQI) and the 12-item General Health Questionnaire (GHQ-12) were used to evaluate subjects' sleep and general mental health. Frequent nightmares were defined as the response of at least once a week in the item of "nightmare" of PSQI. RESULTS: Frequent nightmares were found in 27.3% of subjects. The frequent nightmare group had a higher score of PSQI-sleep duration and PSQI-habitual sleep efficiency (frequent nightmares vs. non-frequent nightmares: PSQI-sleep duration, 1.08 ± 0.97 vs. 0.74 ± 0.85, P < 0.001; PSQI-habitual sleep efficiency, 1.08 ± 1.10 vs. 0.62 ± 0.88, P < 0.001). Reduced sleep duration and reduced sleep efficiency were independently associated with frequent nightmares after adjustment for age, sex, poor mental health, and regular sleeping medication use (reduced sleep duration: OR = 1.96, 95% CI = 1.07-3.58, P = 0.029; reduced sleep efficiency: OR = 2.17, 95% CI = 1.09-4.32, P = 0.027). Subjects with both reduced sleep duration and sleep efficiency were also associated with frequent nightmares (OR = 2.70, 95% CI = 1.57-4.65, P < 0.001). CONCLUSION: The present study found that sleep duration and sleep efficiency were both independently associated with frequent nightmares among frontline medical workers in Wuhan during the COVID-19 pandemic. We should pay attention to nightmares and even the ensuing PTSD symptoms among subjects with reduced sleep duration or sleep efficiency facing potential traumatic exposure.

ACE2 and TMPRSS2 variants and expression as candidates to sex and country differences in COVID-19 severity in Italy Orthopaedic Guidelines for the COVID-19 Post-Outbreak Period: Experience from Wuhan, People's Republic of China

As the outbreak of coronavirus disease 2019 (COVID-19) progresses, prognostic markers for early identification of high-risk individuals are an urgent medical need. Italy has one of the highest numbers of SARS-CoV-2-related deaths and one of the highest mortality rates. Worldwide, a more severe course of COVID-19 is associated with older age, comorbidities, and male sex. Hence, we searched for possible genetic components of COVID-19 severity among Italians by looking at expression levels and variants in ACE2 and TMPRSS2 genes, crucial for viral infection.Exome and SNP-array data from a large Italian cohort were used to compare the rare-variants burden and polymorphisms frequency with Europeans and East Asians. Moreover, we looked into gene expression databases to check for sex-unbalanced expression.While we found no significant evidence that ACE2 is associated with disease severity/sex bias, TMPRSS2 levels and genetic variants proved to be possible candidate disease modulators, prompting for rapid experimental validations on large patient cohorts. Currently, the coronavirus disease 2019 (COVID-19) crisis has rapidly spread worldwide. As the earliest outbreak area of the pandemic, Wuhan, People's Republic of China, is gradually recovering to its normal state under the effective control of government authorities. Outpatient services in major hospitals are now being restored. An accumulation of asymptomatic infections is a potential risk for medical personnel, especially when there is crowding in hospitals. As the biggest center for orthopaedic patients in Wuhan, our orthopaedic outpatient department admits >300 patients per day. Optimal guidelines on how to handle this huge number of patients during the post-outbreak stage of the COVID-19 pandemic, particularly with regard to potential asymptomatic infection, are urgently needed for orthopaedic surgeons. We have developed and proposed applicable guidelines to fill this knowledge gap, including the necessary protective strategies for medical personnel in orthopaedic outpatient and inpatient wards as well as during surgery. We also have provided mental health recommendations for health-care workers. To the best of our knowledge, these guidelines are the first of their kind for orthopaedic surgeons who are slowly reestablishing medical activity following the pandemic.

COVID-19 Orthopaedic Safe Care Toolset: Guidelines for the Diagnosis and Management of Patients with Fracture and COVID-19.

The SARS-CoV-2 (severe acute respiratory syndrome-coronavirus 2) was reported in Wuhan, Hubei Province, People's Republic of China, and, subsequently, in other provinces and regions across the People's Republic of China and >212 countries. COVID-19, the disease caused by this coronavirus, was declared a worldwide pandemic by the World Health Organization (WHO). The incidence of patients with fracture who are also positive for COVID-19 is on the rise. The diagnosis and management of such patients can be complicated as their clinical characteristics are heterogeneous. Furthermore, a surgical procedure can be particularly challenging given that the use of high-speed devices results in aerosol generation. In this study, we develop and propose globally applicable guidelines to fill this knowledge gap and we identify and propose the necessary protective strategies for medical personnel in an orthopaedic emergency department and in the inpatient wards. We also introduce diagnostic criteria, surgical complication management, and follow-up strategies for infected patients. These guidelines may be helpful to decrease the infection rate of orthopaedic trauma personnel and to provide diagnosis and treatment therapy for patients with fracture and COVID-19.
