BackgroundApp-based interventions have the potential to reduce child injury in countries with limited prevention resources, but their effectiveness has not been rigorously examined. ObjectiveThis study aimed to assess the effectiveness of an app-based intervention for caregivers of preschoolers to prevent unintentional injury among Chinese preschoolers. MethodsA 6-month cluster randomized controlled trial was conducted from December 2017 to June 2018. Recruitment was conducted through preschools, which were randomly allocated to either the control group (ie, app-based parenting education excluding unintentional injury prevention) or the intervention group (ie, app-based parenting education including unintentional injury prevention). A total of 2920 caregivers of preschoolers aged 3-6 years from 20 preschools in Changsha, China, were recruited offline through the schools. The primary outcome was unintentional injury incidences among preschoolers in the past 3 months; this measure was assessed through an online caregiver-report at the baseline visit and at 3-month and 6-month follow-up visits. Secondary outcome measures included caregivers’ self-reported attitudes and behaviors concerning child supervision during the last week. Generalized estimating equations (GEEs) were used to assess the effectiveness of the app-based intervention on responses at 3 and 6 months after adjusting for sociodemographic variables, baseline level of the outcome variable, and engagement with interventions in the assigned group. All analyses were intention-to-treat. A per-protocol sensitivity analysis was also conducted. ResultsIn total, 1980 of the 2920 caregivers completed the study. The mean age of participants was 32.0 years (SD 5.5) and 68.99% (1366/1980) of them were female. During the 6-month follow-up visit, unintentional injury incidence did not change significantly in either group: incidence in the intervention group went from 8.76% (94/1073) to 8.11% (87/1073), P=.59; incidence in the control group went from 9.4% (85/907) to 7.5% (69/907), P=.15. The changes did not differ between the groups (odds ratio [OR] 1.14, 95% CI 0.80-1.62). Changes in the average score in attitude concerning unintentional injury prevention were also similar between the groups (B .05, 95% CI -0.03 to 0.13). Changes in unintentional injury prevention behaviors were greater in the intervention group than in the control group after the intervention (B .87, 95% CI 0.33-1.42). Analyses of individual injury prevention behaviors showed that the intervention reduced three risky behaviors: unsafe feeding of children (OR 0.73, 95% CI 0.60-0.89); incorrectly placing children in cars (OR 0.73, 95% CI 0.57-0.93); and allowing children to ride bicycles, electric bicycles, or motorcycles unsupervised (OR 0.80, 95% CI 0.64-0.99). The intervention also improved scores on three safety-focused behaviors: testing water temperature before giving children a bath (OR 1.26, 95% CI 1.05-1.52); properly storing sharp objects (OR 1.24, 95% CI 1.01-1.52); and safely storing medicines, detergents, and pesticides (OR 1.24, 95% CI 1.02-1.51). ConclusionsThe app-based intervention did not reduce unintentional injury incidence among preschoolers but significantly improved caregivers’ safety behaviors. This app-based intervention approach to improve caregiver behaviors surrounding child injury risk offers promise to be modified and ultimately disseminated broadly.

BackgroundWith the growing popularity of mobile health technology, app-based interventions delivered by smartphone have become an increasingly important strategy toward injury prevention. ObjectiveThis study aimed to develop a framework supporting the design of an app-based intervention to prevent unintentional injury, targeted for caregivers of Chinese children aged 0 to 6 years. MethodsA theory-based mixed-method study, including focus groups and Web-based quantitative survey, was performed. Adult caregivers who care for children aged 0 to 6 years and own a smartphone were recruited into 2 sequential stages of research. First, focus groups were conducted among the caregivers at community health care centers and preschools from December 2015 to March 2016. Focus groups (8-10 participants per group) explored awareness, experiences, and opinions of caregivers toward using an app to prevent unintentional injury among children. Second, based on the focus groups findings, a Web-based quantitative survey was designed and distributed to caregivers in November 2016; it collected information on specific needs for the app-based intervention. Thematic analysis and quantitative descriptive analyses were performed. ResultsIn total, 12 focus groups were completed, involving 108 caregivers. Most participants expressed a strong desire to learn knowledge and skills about unintentional child injury prevention and held positive attitudes toward app-based interventions. Participants expressed multiple preferences concerning the app-based intervention, including their contents, functions, interactive styles, installation and registration logistics, and privacy protection and information security. Following the focus groups, 1505 caregivers completed a WeChat-based quantitative survey, which generated roughly similar results to those of focus groups and added numerical metrics concerning participants’ preferences on what to learn, when to learn it, and how to learn it. A detailed framework was established involving 5 components: (1) content design, (2) functional design, (3) interactive style, (4) installation and registration logistics, and (5) privacy protection and information security, and 15 specific requirements. ConclusionsWe developed a framework that can be used as a guide to design app-based interventions for parents and caregivers, specifically for unintentional injury prevention of children aged 0 to 6 years.

Aims: This work aims to analyse the current state of the professional identity of Chinese nurses; examine the relationship amongst regulatory focus, organizational silence and professional identity and determine how regulatory focus affects the relationship between professional identity and organizational silence. Design: This study conducted a cross‐sectional survey. Methods: From June to August 2023, 420 nurses from six hospitals in Hunan Province, China, were selected through convenience sampling and surveyed by using a general information questionnaire, the regulatory focus scale, the organizational silence scale and the professional identity scale. The relationship amongst the regulatory focus, organizational silence and professional identity of nurses was examined by utilizing SPSS 25.0 and the mediating role of regulatory focus between organizational silence and nurses' professional identity was examined by applying AMOS 24.0. Results: Nurses had a moderate level of professional identity. Professional identity was positively correlated with regulatory focus and negatively correlated with organizational silence. Regulatory focus was negatively correlated with organizational silence. Mediation effect studies revealed that organizational silence and professional identity were partially mediated by regulatory focus. Conclusion: In accordance with research showing that nurses' organizational silence can indirectly affect professional identity via regulatory focus, clinical nursing managers should concentrate on the interaction amongst these three variables to strengthen professional identity. Impact: The results of this study serve as a reminder to nurses to select a preventive or promotive focus based on their career objectives and to effectively express their views to enhance their professional identity. This also reminds nursing managers assess nurse‐led regulatory focus, identify their underlying qualities and understand their professional aspirations and career orientation, create a good atmosphere for advice and encourage nurses to express their views, so as to improve nurses 'professional identity.

Introduction: The purpose of this study was to assess the application of the early warning score system (EWS-S) and gauge physician awareness, perceptions of necessity and attitudes regarding these tools based on previously experienced unnoticed clinical deterioration (CDET).Methods: A cross-sectional survey was carried out via an online questionnaire at a large 3,500-bed Class 3A general hospital in China. A total of 299 physicians of adult general wards were asked to answer a translated questionnaire that was localised from the original version. Demographic profiles of patients were included as well as three other sections assessing awareness of CDET/EWS-S and gauging attitudes towards and perceptions of the necessity of EWS-S at our hospital.Results: A high level of physician awareness of the CDET problem was observed. Most physicians knew about the existence of a systematic assessment tool for clinical application. Physicians with previous experience in reanimation, unplanned transfer to intensive care unit (UTICU) and/or death tended to consider EWS-S necessary in attentive and well-trained staff (p < 0.05). Physicians who had previous experience with UTICU were more likely to recommend implementing EWS-S in their wards compared with those without such experience (p < 0.05).Conclusion: Most physicians have positive attitudes towards EWS-S. However, their awareness should be further heightened. Physicians who had previous experience with CDET/UTICU were more likely to employ EWS-S in their clinical practices. To better facilitate the implementation of EWS-S in Chinese hospitals, existing facilities, policy supports, standardised managements and the development of information systems should be strengthened.

Objectives: Central serous chorioretinopathy (CSC) is generally a common fundus disease in young and middle-aged Asian men. Acute and chronic CSC can lead to different degrees of injury to the retinal blood flow. This study aims to observe and compare the blood flow density in different retinal capillary layers in patients with acute and chronic CSC using optical coherence tomography angiography (OCTA) technology., Methods: Twelve patients with acute CSC and 8 patients with chronic CSC including 12 eyes with acute CSC (acute CSC eye group), 11 eyes with chronic CSC (chronic CSC eye group), and 17 normal eyes (normal eye group) were enrolled in this study. All patients underwent 3 mm×3 mm, 6 mm×6 mm macular OCTA scanning. The retinal microvascu-lature was divided into superficial vascular complexes (SVC), intermediate capillary plexuses (ICP), and deep capillary plexuses (DCP) using the projection resolved-OCTA algorithm. Inner retina includes SVC, ICP, and DCP. The vessel density in each retinal layer and the inner retina were calculated and compared., Results: Macular OCTA scanning of 3 mm×3 mm showed that there was no significant difference in blood flow density of SVC and ICP among the 3 groups (both P >0.05); blood flow density of DCP and inner retina in the chronic CSC eye group was significantly lower than that in the acute CSC eye group and the normal eye group (all P <0.05); there was no significant difference in retinal blood flow density of different layer between the acute CSC eye group and the normal eye group (all P >0.05). Macular OCTA scanning of 6 mm×6 mm showed that inner retinal blood flow density of the chronic CSC eye group was significantly lower than that of the acute CSC eye group and the normal eye group (both P <0.05); there was no significant difference in blood flow density of SVC among the 3 groups ( P >0.05)., Conclusions: The vessel density of DCP and inner retina in the eyes with chronic CSC are significantly reduced, which may result in impaired visual function. Therefore, we recommend that patients with acute CSC should be properly treated to avoid progressing into chronic CSC.

Purpose: Idiopathic hypogonadotropic hypogonadism (IHH) and CHARGE (C, coloboma; H, heart abnormalities; A, choanal atresia, R, retardation of growth and/or development; G, gonadal defects; E, ear deformities and deafness) syndrome are 2 distinct developmental disorders sharing features of hypogonadism and/or impaired olfaction. CHD7 variants contribute to >60% CHARGE syndrome and ~10% IHH patients. A variety of extended CHARGE-like features are frequently reported in CHARGE patients harboring CHD7 variants. In this study, we aimed to systematically analyze the diagnostic CHARGE features and the extended CHARGE-like features in patients with IHH with CHD7 variants., Methods: Rare sequencing variants (RSVs) in CHD7 were identified through exome sequencing in 177 IHH probands. Detailed phenotyping was performed in the IHH patients harboring CHD7 variants and their available family members., Results: CHD7 RSVs were identified in 10.2% (18/177) of the IHH probands. Two diagnostic CHARGE features, hearing loss and ear deformities, were significantly enriched in patients with CHD7 variants. Furthermore, CHD7 variants were significantly associated with a panel of extended CHARGE-like phenotypes, including mild ocular defects, dyspepsia/gastroesophageal reflux disease and skeletal defects. We also developed a predictive model for prioritizing CHD7 genetic testing in IHH patients., Conclusion: CHD7 variants rarely cause isolated IHH. Surveillance of symptoms in CHARGE syndrome-affected organs will facilitate the proper treatment for these patients. Certain clinical features can be useful for prioritizing CHD7 genetic screening., (© Endocrine Society 2019. All rights reserved. For permissions, please e-mail: journals.permissions@oup.com.)

Objective: To evaluate the knowledge, attitude and behavior on blood lipid among people in Changsha and to provide evidences for prevention and control of blood lipid abnormality., Methods: A total of 400 cases were randomly selected on the questionnaire of the knowledge, attitude and behavior on blood lipid in ordinary adults who participate in health examination in Xiangya Hospital. Blood lipid related physical examination was conducted at the same time. The health examination participants were divided into several groups according to their sex, age, degree of education, marriage and family income. The influential factors for knowledge, attitude and behavior were analyzed., Results: The knowledge score of blood lipid for health examination participants was 18.33±8.67 (total score 37), the attitude score was 6.63±2.45 (total score 9) and the behavior score was 8.32±2.65 (total score 16). The scores of female was higher than that of male in the terms of knowledge and behavior (both P< 0.05); the scores in the 40-49 age group were lower than those in the other age groups (all P< 0.05); the scores in the junior high school group were lower than those in the other education groups (all P< 0.05); the scores in the family group with less than 2 000 yuan income were lower than those in other family groups with different income (all P< 0.05). The multiple stepwise regression analysis showed that: 1) the knowledge on blood lipid score was influenced by ages and education background (both P< 0.05); 2) while the attitude of blood lipid was influenced by four factors such as education background, systemic blood pressure, blood sugar and triglyceride(all P< 0.05); 3) the behavior on blood lipid was influenced by five factors such education background, triglyceride, systemic blood pressure, blood sugar and ages (all P< 0.05)., Conclusion: The knowledge, attitude and behavior on blood lipid among health examination participants were mostly influenced by education background, gender and ages. Thus, clinical medical staff should prevent the blood lipid abnormality through the health education and improve the knowledge in normal people. The group of 40-49 age male should be thought as the primary intervention subjects. The knowledge, attitude and behavior on blood lipid among the general population is also related to individual's blood pressure, blood sugar and triglyceride. So the clinical medical staff should also improve the knowledge of blood lipid, blood pressure and blood sugar in general population for improving their attitude and unhealthy habits. In addition, the active control of blood sugar and blood pressure can enhance the overall health status of the general population.

Objective: To explore the knowledge of, attitude to and practice in nutrition and food safety, the influence factors, and to provide reference for relevant health education programs., Methods: A total of 510 randomly selected students from Grade 1 to 3 randomly selected were surveyed by a nutrition and food safety questionnaire in Huize of Yunnan Province and Zhen'an of Shaanxi Province. Multiple-linear regression was used to analyze the influence factors of nutrition and food safety., Results: The correct answer rate on nutrition and food safety knowledge of the pupils from Grade 1 to 3 was 74.4%. Nutrition and food safety knowledge score was 11.16±2.51, but only 7.8% of the students correctly answered "How much water should we drink every day". Students who agreed that it is necessary to learn nutrition and food safety knowledge in school accounted for 78.6% and 73.9%, respectively. At least half of the students showed correct behaviors in 7 aspects. The students who ate beans and meat daily or regularly accounted for 28.4% and 34.9%, but only 9.2% of the students drank more than 7 cups of water daily. The multiple-linear regression showed that the major influence factors were the area, grade, status of lodge and singleton., Conclusion: Education is needed for students to form better dietary habits, especially those in low grades, non-singleton, and in board schools.
