Abstract Background The association between age at menarche (AAM) and sleep duration has been affirmed in some studies. The majority of the subjects, however, were teenagers. Given the prevalence of inadequate sleep duration in postmenopausal women, we undertook this study to investigate the association between AAM and sleep duration in postmenopausal women. Methods The study used data from the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2014. Binary logistic regression models were used to assess the association between the AAM and sleep duration, and a subgroup analysis based on age, diabetes, and hypertension was performed. Results Compared to the group with an AAM < 10 years old, women with later AAM have a greater chance of adequate sleep (AAM between 10 and 12 years old: odds ratio (OR) = 2.70, 95% confidence interval (CI): 1.65–4.41, P < 0.001; AAM between 13 and 15 years old: OR = 2.77, 95%CI: 1.70–4.52, P < 0.001; AAM ≥ 16: OR = 2.23, 95%CI: 1.29–3.85, P = 0.004). After we have made several different multivariate-adjusted models, the above conclusions can still be derived ( P < 0.05). In women aged 61 to 71, non-hypertensive patients, and a proportion of patients with diabetes, there is no greater likelihood that other groups will get adequate sleep duration than the reference group ( P > 0.05). Conclusions The effect of the AAM on sleep duration has a long-term effect. It is of great significance to avoid early AAM by actively adjusting lifestyle and other methods to prevent the shortening of sleep duration after menopause.

With the outbreak of novel coronavirus pneumonia (NCP) induced by 2019 novel coronavirus (2019-nCoV) in Wuhan, Hubei Province in December 2019, more and more suspected or confirmed cases have been found in various regions of China. Although China has adopted unprecedented strict quarantine and closed management measures to prevent the spreading of the disease, Department of Traumatic Orthopedics may still have to manage NCP patients with open fractures or severe trauma that require emergency surgery. Therefore, the identification and management of 2019-nCoV infection as soon as possible as well as the protection of all medical staff involved in the emergency treatment of patients are the severe challenges faced by orthopedic traumatologists during the prevention and control of NCP. Based on the characteristics of such patients and related diagnosis and treatment experiences during the epidemic of NCP, the authors formulate the surgical management strategies for orthopedic trauma patients.

Since December 2019, novel coronavirus pneumonia (NCP) has been reported in Wuhan, Hubei Province, and spreads rapidly to all through Hubei Province and even to the whole country. The virus is 2019 novel coronavirus (2019-nCoV), never been seen previously in human, but all the population is generally susceptible. The virus spreads through many ways and is highly infectious, which brings great difficulties to the prevention and control of NCP. Based on the needs of orthopedic trauma patients for emergency surgery and review of the latest NCP diagnosis and treatment strategy and the latest principles and principles of evidence-based medicine in traumatic orthopedics, the authors put forward this expert consensus to systematically standardize the clinical pathway and protective measures of emergency surgery for orthopedic trauma patients during prevention and control of NCP and provide reference for the emergency surgical treatment of orthopedic trauma patients in hospitals at all levels.
