Aim: To develop and test the first causal model of thriving at work in Chinese nurses. Background: Nurses' ability to thrive at their work is critical to retain qualified nurses and meet the needs of a constantly changing health environment. However, this is a poorly researched area. Introduction: Thriving at work refers to the feeling of vitality and learning at work, which are evidenced to be solidly associated with nurses' development. Only a few factors have been explored regarding the effects of thriving at work. Methods: A cross‐sectional study was undertaken using stratified random sampling. This involved 565 nurses from five general hospitals in Dali city, Yunnan Province, People's Republic of China. Data were collected from April to September 2019 using seven instruments. The model was constructed and tested using the Analysis of Moment Structure program and reported using the STROBE checklist. Results: All model variables provided direct and indirect effects to the outcome. The final model fitted the empirical data with acceptable indices. Discussion: Predicting variables of workplace mindfulness, authentic leadership, workplace violence, organizational justice and years of experience were found to affect thriving at work directly and indirectly. Psychological capital and perceived organizational support mediated the effects between predicting variables to the outcome. Conclusion and Implications for nursing and health policy: Recommendations for nursing and health leaders are provided to improve nurses' thriving at work by building fair, supportive, and safe working environments, improving head nurses' authentic leadership and cultivating nurses' mindfulness. Policies need to be promulgated to improve and regulate the nurse–patient ratio and to eliminate violence against Chinese nurses. [ABSTRACT FROM AUTHOR]

Background: Reactivity occurs when research participants alter their behaviours due to the awareness of being monitored, which is a concern with using wearable devices to measure physical activity. The purpose of this study was to examine reactivity to accelerometer measurement among youth with moderate and severe intellectual disabilities (ID). Methods: A sample of 175 youth with ID (108 with moderate and 67 with severe ID) was recruited from residential centres in China. Demographic data were measured using a parent‐reported questionnaire, and light physical activity (LPA) and moderate‐to‐vigorous physical activity (MVPA) were measured using the ActiGraph GT3X accelerometers. Data were analysed using an analysis of covariances where Day 1 LPA/MVPA, Day 2–6 LPA/MVPA, and Day 7 LPA/MVPA were repeated measures. Results: Youth with moderate ID had significantly higher LPA (8.01%) and MVPA (10.30%) on Day 1 than Day 2–6. Similarly, youth with severe ID had significantly higher LPA (21.69%) and MVPA (19.48%) on Day 1 than Day 2–6. An inverse reactivity was also found on Day 7 among youth with severe ID for LPA (−10.65%) and MVPA (−14.82%). Conclusions: Reactivity to accelerometer measurement was found for youth with moderate and severe ID. Findings support the utilisation of a 1‐day familiarisation period, as well as discounting the final day of measurement, when examining physical activity behaviours among youth with moderate and severe ID.

Objectives: Given the increasing prevalence of osteoporosis and the important role dynamic balanced plays in the assessment of muscle function, we aimed to examine the joint and separate effects of osteoporosis and poor dynamic balance on the incidence of sarcopenia in Chinese elderly individuals. Design: This study was conducted on 658 (44.4% male) Chinese suburban-dwelling participants with a mean age of 68.42 ± 5.43 years who initially had no sarcopenia and were aged >60 years. A quantitative ultrasound scan of each participant's calcaneus with a T score less than −2.5 was used to identify the prevalence of osteoporosis. Sarcopenia was diagnosed according to the Asian Working Group for Sarcopenia criteria. We assessed dynamic balance using the Timed Up and Go Test (TUGT). Participants who scored in the top 20% on the TUGT were defined as having poor dynamic balance. Results: After a follow-up of three years, the incidence of sarcopenia in the general population was 8.1% (9.6% in males, 6.8% in females). The incidence of sarcopenia was progressively greater in people suffering from both osteoporosis and poor dynamic balance (OR=2.416, 95%CI=1.124–5.195) compared to those who only had osteoporosis (OR=0.797, 95%CI=0.378–1.682) or poor dynamic balance (OR=1.226, 95%CI=0.447–3.363) in models without adjustments. Even after adjusting for potential confounders, the result still held true (OR=2.431, 95%CI=1.053–5.614). Conclusions: In our study, we found individuals who suffered from both osteoporosis and poor dynamic balance simultaneously had a significantly higher incidence of sarcopenia than those who suffered from either one or the other.

Aim: To investigate nurses' knowledge, attitudes and practices related to physical restraint in tertiary hospitals and identify the factors that influence physical restraint use. Background: Physical restraint is used to maintain patient safety. Nurses play an important role in the restraint process. It is important to identify their understanding, feelings and approach regarding the use of physical restraint. Introduction: Physical restraint is widely practiced in hospitals in China. However, it results in a range of serious negative consequences. This article provides a clear description of nurses' knowledge, attitudes and practices related to physical restraint. Methods: A cross‐sectional survey was conducted. The participants were asked to complete a questionnaire examining their knowledge, attitudes and practices related to physical restraint use. A total of 200 questionnaires were distributed in four tertiary hospitals in Hubei Province, China between August and October 2014. Results: The nurses' responses indicated a good level of knowledge regarding physical restraint use. However, they held some misconceptions. The nurses' attitudes towards physical restraint tended to be neutral. The nurses were well experienced in the use of physical restraint. Nurses who had received on‐the‐job training performed better than those who had received no training related to knowledge and practices regarding physical restraint use. Conclusions and implication for nursing/health policy: In‐service training is highly recommended for nursing managers to improve nurses' physical restraint related knowledge and practices. Regulations regarding the use of restraints should be established as soon as possible by healthcare administration system. Implications for nursing: Nurses should be open to evaluate and improve their views and attitudes regarding effective physical restraint use via multidimensional interventions.

Background: Our previous study suggested that mitochondrial haplogroup F (mtDNA F) was a longevity-associated biomarker, but the effect of mitochondrial haplogroup F on longevity individuals with metabolic syndrome (MetS) was not clear. Thus we explored the association between mtDNA F and MetS among longevity and control population in Guangxi Zhuang Autonomous Region, China.Method: A total of 793 individuals consisting of 307 long-lived participants and 486 local healthy controls were involved in this study. Genotypes of mtDNA F were amplified by polymerase chain reaction and Sanger sequenced. MetS was defined according to the revised National Cholesterol Education Program’s Adult Treatment Panel III (NCEP ATPIII ) criteria.Results: The prevalence of MetS in longevity group (28.0%) was higher than that (18.5%) in control group (P=0.002). Through the case-control stratify analysis, the prevalence of MetS in mtDNA F+ longevity individuals (29.8%) was 4.6 fold higher than that (5.3%) in local control group (P<0.001). However, after further longevity-only analysis, no association between MetS and mtDNA F+ in longevity group was observed (P=0.167). Following same analysis of two variables in control group, we found that the prevalence of MetS in mtDNA F- (95.8%) was higher than that in mtDNA F+ (5.3%); conversely, the prevalence of non-metabolic syndrome (NMetS) in mtDNA F+ (94.7%) was markedly higher than that in mtDNA F- (4.2%) (P<0.001).Conclusion: We demonstrated that mtDNA F+, as a molecuar biomarker, might not only confer beneficial effect to resistance against MetS but also function as a positive factor for long-life span among the population in Guangxi Zhuang Autonomous Region, China.

BackgroundThe self-referential memory (SRM) effect refers to the phenomenon that stimuli processed with reference to the self are better remembered than those referenced to others. Studies have shown that schizophrenia patients do not have this memorial advantage for self-referenced information. The current study investigated the electrophysiological mechanism of the abolished SRM effect in schizophrenia.MethodTwenty schizophrenia patients and 22 controls were recruited to complete an SRM task. We used a high-time resolution event-related potential (ERP) technique to analyze the electrophysiological differences between patients and controls during self- and other-reflection processing.ResultsBehavior data indicated that healthy controls had a typical SRM bias that was absent in the schizophrenia patients. ERP comparison between groups showed that the schizophrenia patients presented smaller voltages in both self- and other-reflection conditions in the 160–260 ms (P2 component) and 800–1200 ms (positive slow wave) time windows over the pre/frontal cortex. Furthermore, the N2 amplitudes (270–380 ms) differed between self- and other-reflection conditions in patients but not in normal controls. More importantly, we found that the P3 amplitudes in the parietal cortex correlated significantly with the SRM bias score in the patients (r = –0.688).ConclusionsThese results provide comprehensive and direct electrophysiological evidence for self- and other-reflective dysfunction in schizophrenia patients and contribute to our understanding of the underlying neural substrates of the abolished SRM effect in schizophrenia.

Zhu XL, Meng HX, Zhang L, Xu L, Chen ZB, Shi D, Feng XH, Zhang X. Association analysis between the −2518MCP-1(A/G) polymorphism and generalized aggressive periodontitis in a Chinese population. J Periodont Res 2012; 47: 286-292. © 2011 John Wiley & Sons A/S Background and Objective: It has been suggested that aggressive periodontitis has a genetic basis. Monocyte chemoattractant protein 1 (MCP-1) plays a critical role in the recruitment of monocytes and the development of periodontitis. The −2518MCP-1(A/G) polymorphism has been implicated as a risk or susceptibility factor for a variety of autoimmune conditions and inflammatory diseases. The intent of this investigation was to study whether the −2518MCP-1(A/G) polymorphism is associated with generalized aggressive periodontitis in the Chinese population. Material and Methods: One hundred and twenty-four patients with generalized aggressive periodontitis and 94 healthy subjects were included in this case-control study. Genomic DNA was isolated from a peripheral blood sample obtained from each subject. Gene polymorphisms of −2518MCP-1(A/G) were analyzed by a standard polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. A logistic regression analysis was performed to test the association between the −2518MCP-1(A/G) genotype (alleles) and generalized aggressive periodontitis with adjustment of the major covariates (gender, age and smoking status). Results: There was no significant association of the −2518MCP-1(A/G) polymorphism with generalized aggressive periodontitis in the unstratified subjects. However, when patients were stratified by gender, the frequency of the G+ genotype was significantly lower in female patients with generalized aggressive periodontitis compared with female controls ( p = 0.036, adjusted odds ratio = 0.3, 95% CI: 0.1-0.9). In female patients with generalized aggressive periodontitis, the probing pocket depth was larger in subjects with the AA genotype than in subjects with the G+ genotype (5.07 mm vs. 4.30 mm; Z = −2.470, p = 0.014). Conclusion: The polymorphisms of −2518MCP-1 may play an important role in determining generalized aggressive periodontitis susceptibility in this cohort of Chinese women. [ABSTRACT FROM AUTHOR]

National-level data on the incidence of retinopathy of prematurity (ROP) in different regions of China is insufficient. This study aimed to compare ROP incidences and care practices in different regions of China and their relationship with regional gross domestic product (GDP) per capita. Retrospective cohort study. All infants born at <32 weeks gestational age (GA) and admitted to 70 neonatal intensive care units (NICUs) from January 1, 2019, to December 31, 2020, were enrolled. Hospitals were categorised into three regional groups according to geographical locations and GDP per capita from high to low: Eastern, Central, and Western China. The incidence of death or ROP, and care practices were compared among the groups. A total of 18,579 infants were enrolled. Median GA was 29.9 (interquartile range 28.4–31.0) weeks and birth weight was 1318.1 (317.2) g. The percentage of GA <28 weeks, complete administration of antenatal steroids, and weight gain velocity during NICU stay were highest in Eastern China and lowest in Western China (all P < 0.01). In Eastern, Central, and Western China, the rates of death or any stage of ROP were 33.3%, 38.5%, and 39.2%, respectively (P < 0.01). There were considerable regional disparities in ROP incidence in preterm infants with GA <32 weeks in China. The incidence of death or ROP ranged from high to low in Western, Central, and Eastern China. [ABSTRACT FROM AUTHOR]
