Association of lifestyle with sleep health in general population in China: a cross-sectional study.

The concept of a healthy lifestyle is receiving increasing attention. This study sought to identify an optimal healthy lifestyle profile associated with sleep health in general population of China. An online cross-sectional survey was conducted from June to July 2022. Six healthy lifestyle factors were assessed: healthy diet, regular physical exercise, never smoking, never drinking alcohol, low sedentary behavior, and normal weight. Participants were categorized into the healthy lifestyle (5-6 factors), average (3-4 factors), and unhealthy lifestyle groups (0-2 factors). The study's primary outcome was sleep health, which included sleep quality, duration, pattern, and the presence of any sleep disorder or disturbance, including insomnia, excessive daytime sleepiness, obstructive apnea syndrome, and narcolepsy. Multivariable logistic regression analysis was applied to explore lifestyles associated with the selected sleep health outcomes. 41,061 individuals were included, forming 18.8% healthy, 63.8% average, and 17.4% unhealthy lifestyle groups. After adjusting for covariates, participants with healthy lifestyle were associated with a higher likelihood of good sleep quality (OR = 1.56, 95% CI = 1.46-1.68), normal sleep duration (OR = 1.60, 95% CI = 1.49-1.72), healthy sleep pattern (OR = 2.15, 95% CI = 2.00-2.31), and lower risks of insomnia (OR = 0.66, 95% CI = 0.61-0.71), excessive daytime sleepiness (OR = 0.66, 95% CI = 0.60-0.73), and obstructive apnea syndrome (OR = 0.40, 95% CI = 0.37-0.43), but not narcolepsy (OR = 0.92, 95% CI = 0.83-1.03), compared to those with unhealthy lifestyle. This large cross-sectional study is the first to our knowledge to quantify the associations of a healthy lifestyle with specific aspects of sleep health. The findings offer support for efforts to improve sleep health by modulating lifestyle.

ALD-induced TiO2/Ag nanofilm for rapid surface photodynamic ion sterilization.

The daily life of people in the intelligent age is inseparable from electronic device, and a number of bacteria on touch screens are increasingly threatening the health of users. Herein, a photocatalytic TiO2/Ag thin film was synthesized on a glass by atomic layer deposition and subsequent in situ reduction. Ultraviolet-visible (UV-Vis) spectra showed that this film can harvest the simulated solar light more efficiently than that of pristine TiO2. The antibacterial tests in vitro showed that the antibacterial efficiency of the TiO2/Ag film against S. aureus and E. coli was 98.2% and 98.6%, under visible light irradiation for 5 min. The underlying mechanism was that the in-situ reduction of Ag on the surface of TiO2 reduced the bandgap of TiO2 from 3.44 to 2.61 eV due to the formation of Schottky heterojunction at the interface between TiO2 and Ag. Thus, TiO2/Ag can generate more reactive oxygen species for bacterial inactivation on the surface of electronic screens. More importantly, the TiO2/Ag film had great biocompatibility with/without light irradiation. The platform not only provides a more convenient choice for the traditional antibacterial mode but also has limitless possibilities for application in the field of billions of touch screens.

Exercise or sport activities for patients with cancer: A protocol for overview of systematic reviews and meta-analyses.

OBJECTIVE: We plan to review all published systematic reviews (SRs) and meta-analyses (MAs) of exercise or sport activities for patients with cancer. The aim of this study is to combine and reanalyze related data and to provide more comprehensive and higher-level evidence. METHODS: We plan to search four English databases and four Chinese databases from inception to June 2019. Patients who were treated by all of exercise or sport activities such as running, gymnastics, taichi, and qigong, will be included. The following information will be extracted from each included SR: first author, year of publication, country of origin, number of primary study; the number of patients enrolled, participant characteristics, duration of cancer diagnosis, cancer types. Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and A Measurements Tool to Assess Systematic Reviews 2 (AMSTAR-2) will be used to assess the reporting and methodological quality of SRs/MAs. The characteristics of included SRs/MAs and their quality will be descriptively summarized using systematically structured tables. The network MA approach and narrative synthesis will be used to examine data when applicable. Odds ratio and (standardized) mean difference with their 95% confidence intervals will be used as summary statistics. Stata 13.0 software will be used to analyze and pool data. RESULTS: The results of the overview will be submitted to a peer-reviewed journal for publication. ETHICS AND DISSEMINATION: The study is not a clinical study, and we will search and evaluate existing sources of literature. So, ethical approval is not required.
