Association between new-onset atrial fibrillation and dementia among individuals with type 2 diabetes.

AIM: To assess the association between new-onset atrial fibrillation and dementia among patients with type 2 diabetes, a group with a high prevalence of atrial fibrillation. MATERIALS AND METHODS: This cohort study included 22 989 patients with type 2 diabetes from the UK Biobank. New-onset atrial fibrillation was ascertained from hospital admission records. We used an algorithm officially released by the UK Biobank to identify all-cause dementia, Alzheimer's disease and vascular dementia. The algorithm was developed using multiple sources, including hospital admissions and the death registry. Time-varying Cox regression analyses were performed to investigate the association between new-onset atrial fibrillation and dementia. RESULTS: A total of 2843 participants developed atrial fibrillation, whereas the remaining 20 146 did not. During the median of 12.3 years of follow-up, 844 all-cause dementia, 342 Alzheimer's disease and 246 vascular dementia cases occurred. Compared with participants without atrial fibrillation, those with atrial fibrillation had higher risks of all-cause dementia (hazard ratio [HR] 2.15, 95% confidence interval [CI] 1.80-2.57), Alzheimer's disease (HR 1.44, 95% CI 1.06-1.96) and vascular dementia (HR 3.11, 95% CI 2.32-4.17). CONCLUSIONS: New-onset atrial fibrillation was associated with a substantially higher risk of all-cause dementia, Alzheimer's disease and vascular dementia in patients with type 2 diabetes. Our findings highlight the significance of atrial fibrillation management in mitigating the risk of dementia in this demographic.

Prevalence of occupational injury and its associated factors among emergency department physicians in China: A large sample, cross-sectional study.

BACKGROUND: Medical personnel, particularly emergency department (ED) physicians, face a variety of occupational hazards. However, the current state of occupational injuries among ED physicians remains unknown. This study aimed to assess the occupational injury of Chinese ED physicians and to identify its associated factors. METHODS: From July to August 2018, a cross-sectional survey was conducted in Chinese emergency departments. A structured questionnaire covering sociodemographic characteristics, individual health behaviours, and work-related characteristics was completed by 10,457 ED physicians. Binary logistic regression was used to analyse the factors associated with occupational injuries. RESULTS: In this study, 81.13% of ED physicians reported occupational injuries in the previous 12 months. All participants who had experienced occupational injuries had suffered verbal violence. Among physicians who experienced at least one injury, 76.57% and 71.30% reported injuries sustained while moving patients and from falls, slips, and sprains during office visits, respectively. Occupational injuries were significantly associated with gender, education level, drinking behaviour, sleep quality, the frequency of night shifts per month, self-perceived physician shortage, and work-family conflict. Physicians who experienced effort-reward imbalance were at a higher risk of occupational injury. CONCLUSION: In China, occupational injuries are common among ED physicians. Individual factors as well as work-related factors are independently linked to occupational injuries. To reduce the rate of occupational injuries among ED physicians, health policymakers and healthcare facility managers should consider multi-injury interventions.

L-shaped association between lean body mass to visceral fat mass ratio with hyperuricemia: a cross-sectional study.

BACKGROUND: Insufficient attention has been given to examining the correlation between body composition and hyperuricemia, leading to inconsistent findings. The primary objective of this research is to explore the association between lean body mass index (LMI), visceral fat mass index (VFMI), and hyperuricemia. A specific emphasis will be placed on assessing the link between the ratio of lean body mass to visceral fat mass (LMI/VFMI) and hyperuricemia. METHODS: The present study employed a cross-sectional design and involved a total of 9,646 individuals who participated in the National Health and Nutrition Examination Survey (NHANES). To explore the associations among the variables, logistic and linear regressions were employed. Additionally, subgroup analyses and sensitivity analyses were conducted based on various characteristics. RESULTS: The results showed that LMI was positively associated with hyperuricemia (for Per-SD: OR = 1.88, 95%CI: 1.75, 2.01; for quartiles [Q4:Q1]: OR = 5.37, 95%CI: 4.31, 6.69). Meanwhile, VFMI showed a positive association with hyperuricemia (for Per-SD: OR = 2.02, 95%CI: 1.88, 2.16; for quartiles [Q4:Q1]: OR =8.37, 95%CI: 6.70, 10.47). When considering the effects of In LMI/VFMI, an L-shaped negative association with hyperuricemia was observed (for Per-SD: OR = 0.45, 95%CI: 0.42, 0.49; for quartiles [Q4:Q1]: OR = 0.16, 95%CI: 0.13, 0.20). Subgroup and sensitivity analyses demonstrated the robustness of this association across different subgroups. Additionally, the segmented regression analysis indicated a saturation effect of 5.64 for the In LMI/VFMI with hyperuricemia (OR = 0.20, 95%CI: 0.17, 0.24). For every 2.72-fold increase of In LMI/VFMI, the risk of hyperuricemia was reduced by 80%. CONCLUSION: The LMI/VFMI ratio is non-linearly associated with serum uric acid. Whether this association is causal needs to be confirmed in further longitudinal studies or Mendelian randomization.

High Precision Positioning and Rotation Angle Estimation of a Flatbed Truck Based on BDS and Vision.

Centimeter-level localization and precise rotation angle estimation for flatbed trucks pose significant challenges in unmanned forklift automated loading scenarios. To address this issue, the study proposed a method for high-precision positioning and rotation angle estimation of flatbed trucks using the BeiDou Navigation Satellite System (BDS) and vision technology. First, an unmanned forklift equipped with a Time-of-Flight (ToF) camera and a dual-antenna mobile receiver for BDS positioning collected depth images and localization data near the front and rear endpoints of the flatbed. The Deep Dual-Resolution Network-23-slim (DDRNet-23-slim) model was used to segment the flatbed from the depth image and extract the straight lines at the edges of the flatbed using the Hough transform. The algorithm then computed the set of intersection points of the lines. A neighborhood feature vector was designed to identify the endpoint of a flatbed from a set of intersection points using feature screening. Finally, the relative coordinates of the endpoints were converted to a customized forklift navigation coordinate system by BDS positioning. A rotation angle estimation was then performed using the endpoints at the front and rear. Experiments showed that the endpoint positioning error was less than 3 cm, and the rotation angle estimation error was less than 0.3°, which verified the validity and reliability of the method.

High-Precision Positioning and Rotation Angle Estimation for a Target Pallet Based on BeiDou Navigation Satellite System and Vision.

In outdoor unmanned forklift unloading scenarios, pallet detection and localization face challenges posed by uncontrollable lighting conditions. Furthermore, the stacking and close arrangement of pallets also increase the difficulty of positioning a target pallet. To solve these problems, a method for high-precision positioning and rotation angle estimation for a target pallet using the BeiDou Navigation Satellite System (BDS) and vision is proposed. Deep dual-resolution networks (DDRNets) are used to segment the pallet from depth images and RGB images. Then, keypoints for calculating the position and rotation angle are extracted and further combined with the 3D point cloud data to achieve accurate pallet positioning. Constraining the pixel coordinates and depth coordinates of the center point of the pallet and setting the priority of the pallet according to the unloading direction allow the target pallet to be identified from multiple pallets. The positioning of the target pallet in the forklift navigation coordinate system is achieved by integrating BDS positioning data through coordinate transformation. This method is robust in response to lighting influences and can accurately locate the target pallet. The experimental results show that the pallet positioning error is less than 20 mm, and the rotation angle error is less than 0.37°, which meets the accuracy requirements for automated forklift operations.

Systemic chemotherapy plus transarterial chemoembolization versus systemic chemotherapy alone for unresectable intrahepatic cholangiocarcinoma: a multicenter retrospective cohort study.

PURPOSE: Systemic chemotherapy (SYS) is the first-line treatment of unresectable intrahepatic cholangiocarcinoma (ICC). However, the survival benefit of SYS is still limited. This study compared the efficacy and safety of patients with unresectable ICC treated with transarterial chemoembolization (TACE) plus SYS to SYS alone. MATERIAL AND METHODS: The multicenter retrospective cohort study included patients aged ≥ 18 years old with pathologically diagnosed ICC. Patients with unmeasurable lesions, not receiving SYS treatment, Child-Pugh grade C, Eastern Cooperative Oncology Group performance status score of 3 or higher, prior liver resection, incomplete medical information, or discontinuation of the first SYS treatment were excluded. Data collection was mainly from the hospital system, and the survival outcome of patients was obtained through follow-up. Overall survival (OS) was estimated using the Kaplan-Meier method and compared using the log-rank test. Propensity score matching at a 1:1 ratio using the nearest neighbor matching algorithm was performed to reduce selection bias between the TACE plus SYS and SYS alone groups. The Cox proportional hazards model was used to identify prognostic factors associated with OS and to estimate their hazard ratios. Modified Response Evaluation Criteria in Solid Tumors criteria were utilized to evaluate the response of tumors to therapy. RESULTS: Between June 2016 and February 2023, 118 unresectable ICC patients from three hospitals were included in this study. Of them, 37 were in the TACE plus SYS group and 81 were in the SYS alone group. The median OS in the combination group was 11.3 months, longer than the 6.4 months in the SYS alone group (P = 0.011). A greater objective response rate (ORR) and disease control rate (DCR) were observed in the combination group than in the SYS alone group (ORR, 48.65 vs. 6.17%, P < 0.001; DCR, 89.19 vs. 62.96%, P = 0.004). There were 16 patients in each group after matching, and the matched results remained consistent regarding OS and tumor response. Adverse events (AEs) were similar in the two groups after matching. CONCLUSION: Compared to SYS alone, the combination treatment of TACE plus SYS was more effective than SYS alone in improving OS, ORR, and DCR without any significant increase in AEs. TACE plus SYS may be a viable treatment option for patients with unresectable ICC.

Body weight, weight change and the risk of cardiovascular disease in patients with hypertension: a primary-care cohort study.

BACKGROUND/OBJECTIVES: Obesity and cardiovascular disease (CVD) often co-occur. However, the effects of excessive body weight and weight change on CVD in patients with hypertension are not clearly established. We examined the associations of BMI, weight change and the risk of CVD in patients with hypertension. SUBJECTS/METHODS: Our Data were drawn from the medical records of primary-care institutions in China. A total of 24,750 patients with valid weight measurements attending primary healthcare centers were included. Body weight were grouped in BMI categories of underweight ( < 18.5 kg/m2), healthy weight (18.5-22.9 kg/m2), overweight (23.0-24.9 kg/m2) and obesity ( ≥ 25.0 kg/m2). Weight change over 12 months was divided into: gain >4%, gain 1-4%, stable (-1 to 1%), loss 1-4%, and loss ≥4%. Cox regression analyses were used to estimate hazard ratio (HR) and 95% confidence interval (95% CI) between BMI, weight change and the risk of CVD. RESULTS: After multivariable adjustment, patients with obesity were related to higher risks of CVD (HR = 1.48, 95% CI: 1.19-1.85). Higher risks were seen in participants with loss ≥4% and gain >4% of body weight compared to stable weight (loss ≥4%: HR = 1.33, 95% CI: 1.04-1.70; gain >4%: HR = 1.36, 95% CI: 1.04-1.77). CONCLUSION: Obesity and weight change of loss ≥4% and gain >4% were related to higher risks of CVD. Close monitoring and appropriate interventions aimed at achieving an optimal weight are needed to prevent adverse cardiovascular outcomes for patients with hypertension.

Rates of perceived medical errors and its correlation with work-related factors and personal distress among emergency physicians in China: a national cross-sectional study.

PURPOSE: Medical errors are a global concern, and specifically, EDs are at considerable risk for medical errors. Few studies focus on the healthcare provider's self-perceived medical errors in hospitals, let alone the ED. Hence, this study explored perceived medical errors and their correlation with work-related factors and personal distress among physicians in EDs in China. METHODS: From July 2018 to August 2018, a national web-based cross-sectional study was conducted. The link to the web-based questionnaire was posted on the emergency physicians' working platform, inviting Chinese licensed emergency physicians to participate anonymously in this survey. Our outcome of interest, medical errors, was investigated using self-reporting methods. Occupational stress was assessed using the Chinese version of the Effort-Reward Imbalance scale. The Patient Health Questionnaire, the subscale of the 10-item Positive and Negative Affect Schedule, the subscale of the validated Leiden Quality of Work Questionnaire and the 10-item Generalised Self-efficacy Scale were used to assess personal distress. Logistic regression analysis was used to determine factors significantly associated with perceived medical errors. RESULTS: A sample of 10 457 emergency physicians completed the survey. Almost half (43.63%) of physicians reported self-perceived medical errors during the previous 3 months. The rate of workplace verbal aggression, effort-reward imbalance and depressive symptoms were 81.81%, 78.39% and 35.71%, respectively. Medical errors were more likely to be reported among chief physicians, and those who reported the department was short-staffed for physicians, and who experienced workplace verbal aggression and intense work stress. Medical errors were significantly associated with negative affect and lower self-efficacy. CONCLUSION: Self-perceived medical errors are prevalent among physicians working in EDs and are associated with their workplace environment and personal distress. Targeted interventions are required to reduce physicians' workload and improve their working environment. Accounting for healthcare providers' distress is imperative for reducing the incidence of medical errors and improving their health.

The effects of effort-reward imbalance on emergency nurses' turnover intention: The mediating role of depressive symptoms.

OBJECTIVES: This study investigated the effects of effort-reward imbalance (ERI) on emergency nurses' turnover intention and the role of depressive symptoms between ERI and turnover intention. BACKGROUND: Turnover intention is crucial for clinical practice due to its relationship with turnover behaviour and destructive effect on stability of nursing staff. The ERI is a mainstream model to explain job stress, which seems to be one of the key variables, but the direct evidence is not adequate. In addition, there have been only a few studies looking into the complexity of the relationship between ERI and turnover intention, and more research is needed. METHODS: This is a cross-sectional study conducted from July to August 2018, and the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines were followed. We employed a standardised questionnaire to collect sociodemographic information and target turnover intention. Hierarchical multiple logistic regression and mediation analyses were performed for the data analyses. RESULTS: This study included responses from 17,582 emergency nurses in China. On turnover intention, ERI exerted both direct effect and indirect mediating effect. The results also indicate that depressive symptoms partially mediated the effect of ERI on turnover intention, and that 27.4% of this effect can be explained by mediating effects. CONCLUSIONS: To improve the turnover intention, it is necessary to consider reducing ERI and depressive symptoms of emergency nurses as powerful measures not to be ignored. RELEVANCE TO CLINICAL PRACTICE: This study provides important insights regarding how nursing administrators should better reduce the workload of caregivers and improve depressive symptoms to avoid turnover intention.

Occurrence of self-perceived medical errors and its related influencing factors among emergency department nurses.

AIMS AND OBJECTIVES: To determine the prevalence and the associated factors of self-perceived medical errors among Chinese emergency department nurses. BACKGROUND: The emergency department is a place with a high incidence of medical errors. Studies about the occurrence and related influencing factors of medical errors among emergency nurses in China are very insufficient. DESIGN: A nationwide cross-sectional study. METHODS: A nationwide cross-sectional study was conducted from July 2018-August 2018. A total of 17,582 emergency department nurses from 31 provinces across China were eventually included in the analysis. Logistic regression is applied to examine the association of the independent variables with the perceived medical errors. The reporting of this study was compliant with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist for cross-sectional studies. RESULTS: Of 17,582 participating nurses, 4445 (25.28%) reported self-perceived medical errors in the past 3 months. Nurses who were serving as nurses-in-charge; who reported fair or bad physical health; who reported staff shortage; who were exposed to more verbal abuse at work; who experienced effort-reward imbalance; who reported more over-commitment; or who had depressive symptoms were more likely to report medical errors. Older age and female gender were protective factors. CONCLUSIONS: In this study, a quarter of the emergency nurses reported that they had made medical errors in the past 3 months. Self-perceived medical errors are associated with multiple domains of work-related factors and personal distress. Feasible measures should be taken to reduce nurses' workload, improve their working environment, monitor and minimise the occurrence of medical errors among emergency department nurses. RELEVANCE TO CLINICAL PRACTICE: Emergency nurses, who are the most frequently in contact with patients, play an important role in identifying risk factors and preventing medical errors. Identifying risk factors that may lead to medical errors in the medical environment from both internal and external aspects will help nursing practitioners, hospital administrators and policy makers to take timely preventive measures to reduce the occurrence of medical errors and reduce harm to patients.

Factors related to turnover intention among emergency department nurses in China: A nationwide cross-sectional study.

BACKGROUND: Turnover intention among nurses is high, especially in the emergency department. However, factors that are associated with Chinese emergency department nurses' turnover intention have been scarcely studied. AIMS: The present study examined relationships between turnover intention and demographic characteristics, job-related factors, depressive symptoms, and organizational commitment among emergency department nurses. STUDY DESIGN: A cross-sectional study of emergency department nurses was conducted in China between July and August 2018. The questionnaire included demographic characteristics (age, gender, level of education, and self-rated health status), job-related factors (qualification title, job seniority, night shifts, and workplace violence), depressive symptoms, organizational commitment, and turnover intention. A hierarchical linear regression model was used to identify factors that are associated with turnover intention among emergency department nurses. RESULTS: A total of 17 582 emergency department nurses participated in the study. The response rate was 68.9%. The findings indicated that poor self-rated health status (ß = 0.25, p < .001), working more than 11 night shifts per month (ß = 0.14, p < .01), experiencing workplace violence in the past year (ß = 0.08, p < .05), and higher depressive symptom scores (ß = 0.07, p < .001) positively correlated with turnover intention. More years of service (ß = -0.38, p < .001) and higher organizational commitment scores (ß = -0.45, p < .001) negatively correlated with turnover intention. CONCLUSIONS: Health status, job seniority, night shift frequency per month, workplace violence, depressive symptoms, and organizational commitment were significantly associated with emergency department nurses' turnover intention. RELEVANCE TO CLINICAL PRACTICE: To reduce turnover intention in the emergency department nurses, hospital administrators and managers should implement measures to improve their physical and mental health, increase organizational commitment, develop staff acceptable shift schedules, and reduce incidences of workplace violence.

Effectiveness of Systemic Corticosteroids Therapy for Nonsevere Patients With COVID-19: A Multicenter, Retrospective, Longitudinal Cohort Study.

OBJECTIVES: Corticosteroids were clinically used in the treatment of nonsevere patients with COVID-19, but the efficacy of such treatment lacked sufficient clinical evidence, and the impact of dose had never been studied. This study aimed to evaluate the effect of systemic corticosteroid use (SCU) in nonsevere patients with COVID-19. METHODS: We conducted a multicenter retrospective cohort study in Hubei Province. A total of 1726 patients admitted with nonsevere type COVID-19 were included. Mixed-effect Cox model, mixed-effect Cox model with time-varying exposure, multiple linear regression, and propensity score analysis (inverse probability of treatment weight and propensity score matching) were used to explore the association between SCU and progression into severe type, all-cause mortality, and length of stay. RESULTS: During the follow-up of 30 days, 29.8% of nonsevere patients with COVID-19 received treatment with systemic corticosteroids. The use of systemic corticosteroids was associated with higher probability of developing severe type (adjusted hazard ratio 1.81; 95% confidence interval 1.47-2.21), all-cause mortality (adjusted hazard ratio 2.92; 95% confidence interval 1.39-6.15) in time-varying Cox analysis, and prolonged hospitalization (ß 4.14; P < .001) in multiple linear regression. Analysis with 2 propensity score cohorts displayed similar results. Besides, increased corticosteroid dose was significantly associated with elevated probability of developing severe type (P < .001) and prolonged hospitalization (P < .001). CONCLUSIONS: Corticosteroid treatment against nonsevere patients with COVID-19 was significantly associated with worse clinical outcomes. The higher dose was significantly associated with elevated risk of poor disease progression. We recommend that SCU should be avoided unless necessary among nonsevere patients with COVID-19.

Prevalence of inappropriate use behaviors of antibiotics and related factors among chinese antibiotic users: an online cross-sectional survey.

BACKGROUND: Inappropriate use of antibiotics could have a profound negative impact on individual and community. This study aimed to assess the prevalence of inappropriate use behaviors of antibiotics in Chinese antibiotic users and explored their related factors. METHODS: A cross-sectional survey was conducted from July 1, 2018 to September 30, 2018. A structured questionnaire was widely distributed on the online survey platform (Questionnaire Star, https://www.wjx.cn ) and was used to collect data from respondents in China on demographic and sociological characteristics, antibiotic use and related knowledge. Main outcomes included self-medication with antibiotics (SMA), self-storage with antibiotics (SSA), and non-adherence to antibiotic treatment (NAAT). Logistic regression was used to identify the related factors of above inappropriate use behaviors of antibiotics. RESULTS: Of the 15,526 participants, 37.1% reported SMA in the past 6 months, 67.9% reported SSA in the past 6 months, and 48.3%, 15.2%, 25.5% and 78.0% of respondents said that they had missed antibiotics, increased antibiotic dosage, decreased antibiotic dosage, and discontinued antibiotics once symptoms disappear, respectively. Overall, 53.3% reported NAAT during this period. After adjusting for other variables, multivariate logistic regression analyses showed that those aged 30-44 years old, with higher levels of education, poorer status of self-perceived health, or lower levels of antibiotic knowledge were more likely to have these inappropriate use behaviors of SMA, SSA, and NAAT (P < 0.05). CONCLUSIONS: The prevalence of SMA, SSA, and NAAT is high in China. Developing a nationwide action plan for the rational use of antibiotics among publics, including national media publicity, online and offline health education, and medication guidance from general practitioners, is urgently needed.

Development and validation of a maternal anxiety for neonatal jaundice scale in China.

BACKGROUND: Maternal anxiety induced by neonatal jaundice has adverse effects on maternal and infant health, but there was no specific tool to identify the anxiety level of mothers. This study aims to develop a Maternal Anxiety for Neonatal Jaundice Scale (MANJS) and to validate it in the target population. METHODS: An initial 11-items MANJS was developed through literature review, expert panel consultation, and a pilot-test. Subsequently, mothers of neonates with jaundice were recruited from the Maternal and Child Health Hospital of Hainan Province, China, from June to December 2018, for a formal questionnaire survey. Based on the data collected, the scale was validated for construct validity, convergent validity, discriminant validity, content validity, and internal consistency reliability after the items screening. RESULTS: The reliability and validity of MANJS were validated in 1127 mothers of jaundiced neonates. After the item with cross-loadings was removed using exploratory factor analysis, MANJS consisted of two dimensions and 10 items, with a cumulative variance contribution of 74.36% and factor loadings above 0.6 for all items. The confirmatory factor analysis identified three items with cross-factor loading or error correlation and then they were removed orderly. The further confirmatory factor analysis showed a good construct validity for the 7-item MANJS, with standardized root mean square residual (SRMR) = 0.029, root mean square error of approximation (RMSEA) = 0.068, comparative fit index (CFI) = 0.961, Tucker-Lewis index (TLI) = 0.937, incremental fit index (IFI) = 0.961, normed fit index (NFI) = 0.954, goodness of fit index (GFI) = 0.998, adjusted goodness of fit index (AGFI) = 0.996, respectively. The average variance extracted values (AVE) of the two factors were 0.80 and 0.72, and the combined reliability (CR) were 0.94 and 0.88, respectively. Cronbach's alpha was 0.90 for the MANJS, and split-half reliability was 0.72. CONCLUSIONS: MANJS was demonstrated to have satisfactory reliability and validity in evaluating maternal anxiety caused by neonatal jaundice among Chinese postpartum women.

Effects of a Smartphone-Based Out-of-Hospital Screening App for Neonatal Hyperbilirubinemia on Neonatal Readmission Rates and Maternal Anxiety: Randomized Controlled Trial.

BACKGROUND: Neonatal hyperbilirubinemia is one of the leading causes of neonatal readmission-especially severe hyperbilirubinemia and its complications-and it influences disease burden as well as neonatal and maternal health. Smartphones have been shown to have satisfactory accuracy in screening neonatal bilirubin levels, but the impact of this technology on neonatal health care service and maternal health outcomes is still unknown. OBJECTIVE: The aim of this study was to evaluate the impact of a smartphone-based out-of-hospital neonatal jaundice screening program on neonatal readmission rates for jaundice and related maternal anxiety. METHODS: This was a 2-arm, unblinded, randomized controlled trial with 30 days of intervention and follow-up periods. From August 2019 to August 2020, healthy mother-infant dyads were recruited on-site from 3 public hospitals in Hainan, China. Intervention group mothers used the smartphone app to routinely monitor neonatal jaundice at home under the web-based guidance of pediatricians. Control group participants received routine care. The primary study outcome was the neonatal readmission rate due to jaundice within 30 days of the first hospital discharge. The secondary outcome was the maternal anxiety score associated with neonatal jaundice. The data were collected through a self-assessed questionnaire. All participants were included in the analysis (intention-to-treat). RESULTS: In this study, 1424 mother-infant dyads were recruited, comprising 1424 mothers and 1424 newborns. The median age of the mothers was 29 (IQR 26-32) years, and there were 714 (50.1%) male neonates. These mother-infant dyads were randomly assigned to the intervention group and the control group, with 712 dyads in each group; only 1187 of these dyads completed the follow-up. We found that the adjusted 30-day neonatal readmission rate due to jaundice reduced by 10.5% (71/605, 11.7% vs 141/582, 24.2%; 95% CI 5%-15.9%; odds ratio 0.4, 95% CI 0.3-0.5; P<.001) and the relevant maternal anxiety mean score decreased by 3.6 (95% CI -4.4 to -2.8; ß=-3.6, 95% CI -4.5 to -2.8; P<.001) in the intervention group compared to those in the routine care group. CONCLUSIONS: Our study shows that the smartphone-based out-of-hospital screening method for neonatal hyperbilirubinemia decreased the neonatal readmission rate within 30 days from the first discharge and improved maternal mental health to some degree, thus demonstrating the usefulness of this screening app for follow-up in pediatric care.

Interrupted Time-Series Analysis to Evaluate the Impact of a National Antimicrobial Stewardship Campaign on Antibiotic Prescribing: A Typical Practice in China's Primary Care.

BACKGROUND: After implementing the 2011 national antimicrobial stewardship campaign, few studies focused on evaluating its effect in China's primary care facilities. METHODS: We randomly selected 11 community health centers in Shenzhen, China, and collected all outpatient prescriptions of these centers from 2010 to 2015. To evaluate the impact of local interventions on antibiotic prescribing, we used a segmented regression model of interrupted time series to analyze 7 outcomes (ie, percentage of prescriptions with antibiotics, and percentages of prescriptions with broad-spectrum antibiotics, with parenteral antibiotics, and with 2 or more antibiotics in all prescriptions or antibiotic-containing prescriptions). RESULTS: Overall, 1 482 223 outpatient prescriptions were obtained. The intervention was associated with a significant immediate change (-5.2%, P = .04) and change in slope (-3.1% per month, P < .01) for the percentage of prescriptions with antibiotics, and its relative cumulative effect at the end of the study was -74.0% (95% confidence interval, -79.0 to -69.1). After the intervention, the percentage of prescriptions with broad-spectrum and with parenteral antibiotics decreased dramatically by 36.7% and 77.3%, respectively, but their percentages in antibiotic-containing prescriptions decreased insignificantly. Percentage of prescriptions with two or more antibiotics in all prescriptions or antibiotic-containing prescriptions only showed immediate changes, but significant changes in slope were not observed. CONCLUSIONS: A typical practice in Shenzhen, China, showed that strict enforcement of the antimicrobial stewardship campaign could effectively reduce antibiotic prescribing in primary care with a stable long-term effect. However, prescribing of broad-spectrum and parenteral antibiotics was still prevalent. More targeted interventions are required to promote appropriate antibiotic use.

Evaluating effort-reward imbalance among nurses in emergency departments: a cross-sectional study in China.

BACKGROUND: Effort-reward imbalance is an adverse psychological response to working conditions that has several negative effects on nurses. However, there is little research on effort-reward imbalance and its influencing factors among nurses in emergency departments. This study aimed to understand the current situation of effort-reward imbalance and explore its influencing factors among emergency department nurses in China. METHODS: From July to August 2018, a structured online questionnaire survey was conducted among emergency department nurses in China. Data were collected from emergency department nurses employed in hospitals providing pre-hospital care in China. The questionnaire consisted of sociodemographic characteristics, work-related factors and effort-reward imbalance. A descriptive analysis and a binary logistic regression were conducted to explore the effort-reward imbalance and its influencing factors among emergency department nurses. RESULTS: The study involved 17,582 emergency department nurses; notably, the prevalence of effort-reward imbalance was 59.66%. The participating nurses who were males, aged 25 to 34 years, whose educational level was a bachelor degree or above, who had a junior or above title, who had longer years of service, and who had suffered verbal or physical violence in the past year had a higher risk of effort-reward imbalance. Furthermore, the nurses with a high monthly income, who believed that the number of nurses met the department's demand had a lower risk of effort-reward imbalance. CONCLUSIONS: Effort-reward imbalance was prevalent among emergency department nurses in China. Measures such as adjusting the night shift frequency, increasing the number of nurses, raising salaries and reducing workplace violence should be considered to reduce the level of effort-reward imbalance.

Over-the-counter antibiotic sales in community and online pharmacies, China.

OBJECTIVE: To determine the prevalence of and factors associated with dispensing antibiotics without a prescription in online and community pharmacies in China. METHODS: We conducted a nationwide cross-sectional study of online and community pharmacies in 27 cities and counties in nine provinces in China (selected by multistage sampling) from July 2017 to December 2018. We assessed sale of antibiotics without a prescription and quality of pharmacy services through simulated clients who asked to buy specific antibiotics. We compared the prevalence of sales between online and community pharmacies, and between location and features of community pharmacies. FINDINGS: Of 220 online and 675 community pharmacies, 174 (79.1%) and 586 (86.8%) sold antibiotics without a valid prescription, respectively. About half of the online pharmacies had a notice on their website about the illegality of selling prescription-only medicines without a prescription while none of the community pharmacists had. More online pharmacies without this notice dispensed antibiotics without a valid prescription (P < 0.001). Antibiotics' sale without a prescription was significantly less prevalent in provincial capital cities (71.6%; 161/225) than prefectural-level cities (95.1%; 214/225) and counties (93.8%; 211/225; P < 0.001). Most pharmacy staff did not ask for important information from clients before dispensing the antibiotic or provide them with necessary information about the antibiotic. CONCLUSION: Given the high proportion of sales of prescription-only medicines without a prescription, there is a need to strengthen enforcement of regulations, improve public education on antibiotics, train pharmacy staff and consolidate public involvement in antibiotic stewardship in retail pharmacies in China.

Factors associated with Chinese pregnant women's preference for a cesarean section based on the theory of planned behaviour.

OBJECTIVES: Cesarean delivery on maternal request is one of the important public health issues in China. Our study aimed to apply the theory of planned behaviour to comprehensively determine the factors regarding pregnant women's preference for cesarean section and to provide references for establishing measures to reduce cesarean delivery on maternal request. METHODS: This cross-sectional analysis was conducted in four women's and children's hospitals in China from May to June 2018. Eligible women arriving for routine antenatal visits at these hospitals were recruited to answer a structured questionnaire. A total of 1853 pregnant women consented to participate in the investigation, with a response rate of 88.75%. Finally, 1677 pregnant women (984 nulliparae and 693 multiparae) were involved in the analysis. Descriptive statistics and logistic regression analyses were used. RESULTS: Of the study participants, 20.39% preferred cesarean section. For both nulliparae and multiparae, those who had lower scores of attitudes towards vaginal delivery, lower scores of childbirth self-efficacy and higher scores of subjective norms were more likely to prefer cesarean section. CONCLUSIONS: Pregnant women's birth preferences were significantly associated with their attitudes towards the delivery mode, childbirth self-efficacy and subjective norms, which is consistent with the theory of planned behaviour. Interventions to reduce cesarean delivery on maternal request can be developed based on the theory of planned behaviour.

OBJECTIFS: L'accouchement par césarienne à la demande de la mère est l'un des principaux problèmes de santé publique en Chine. Notre étude visait à appliquer la théorie du comportement planifié afin de déterminer de manière exhaustive les facteurs associés à la préférence des femmes enceintes pour la césarienne, et de fournir des références pour établir des mesures visant à réduire l'accouchement par césarienne à la demande de la mère. MÉTHODES: Cette analyse transversale a été réalisée dans quatre hôpitaux pour femmes et enfants en Chine de mai à juin 2018. Des femmes éligibles arrivant pour des visites prénatales de routine dans ces hôpitaux ont été recrutées pour répondre à un questionnaire structuré. Au total, 1.853 femmes enceintes ont consenti à participer à l'enquête, avec un taux de réponse de 88,75%. AU total, 1.677 femmes enceintes (984 nullipares et 693 multipares) ont été incluses dans l'analyse. Des statistiques descriptives et des analyses de régression logistique ont été utilisées. RÉSULTATS: Parmi les participantes à l'étude, 20,39% ont préféré une césarienne. Pour les nullipares et les multipares, celles qui avaient des scores d'attitudes plus faibles envers l'accouchement vaginal, des scores plus faibles de l'efficacité propre de l'accouchement et des scores plus élevés des normes subjectives étaient plus susceptibles de préférer la césarienne. CONCLUSIONS: Les préférences d'accouchement des femmes enceintes étaient significativement associées à leurs attitudes à l'égard du mode d'accouchement, de l'efficacité propre de l'accouchement et des normes subjectives, ce qui est conforme à la théorie du comportement planifié. Des interventions pour réduire l'accouchement par césarienne à la demande de la mère peuvent être développées sur la base de la théorie du comportement planifié.

Development and nationwide application of an antibiotic knowledge scale.

Misconceptions about antibiotics among the public can potentially lead to their inappropriate use. Currently, there is no antibiotic knowledge assessment tool to address this issue. This study aimed to develop and validate an antibiotic knowledge scale (AKS) and apply this scale to assess public knowledge about antibiotics in China. An initial 18-item AKS was designed and validated among 1180 people recruited in June 2017. After removing redundant items, the reliability and validity of the AKS were examined. Subsequently, a nationwide survey was conducted, and 12,772 people were recruited using multistage sampling and surveyed using the developed AKS. A logistic regression model was used to identify the factors associated with poor knowledge about antibiotics. The final AKS included two screening items and fifteen knowledge evaluation items. Cronbach's alpha, test-retest reliability, and split-half reliability were 0.91, 0.88, and 0.89, respectively. These knowledge evaluation items were loaded in four distinct factors that explained 70.72% of cumulative variance among respondents. Using the developed AKS to assess public knowledge about antibiotics among 12,772 participants, the mean score on the AKS was 7.25 and 67% of participants had poor antibiotic knowledge, which was associated with male gender, rural residence, lower educational level, poor economic status, living in western China, and lacking education on antibiotics. The AKS demonstrated satisfactory reliability and validity in identifying the population with poor antibiotic knowledge. Importantly, the majority of participants had inadequate knowledge about antibiotics. Thus, it is necessary to conduct interventions focusing on improving public knowledge about antibiotics.
