Our evaluation on the independent test set showed that most types of feature were beneficial to Chinese NER systems, although the improvements were limited. The system achieved the highest performance by combining word segmentation and section information, indicating that these two types of feature complement each other. When the same types of optimized feature were used, CRF and SSVM outperformed SVM and ME. More specifically, SSVM achieved the highest performance of the four algorithms, with F-measures of 93.51% and 90.01% for admission notes and discharge summaries, respectively.

Aims and objectives This study aimed to obtain the incidence of diastasis recti abdominis (DRA) and analyse possible risk factors in adult females. Moreover, the relationships between DRA and lower back pain, pelvic floor function and quality of life were also analysed. Background Diastasis recti abdominis is a separation of the abdominal muscles at the linea alba. Currently, studies on the prevalence rates, risk factors and consequences of DRA are varied. In particular, reports on DRA among adult women are lacking. Design A one‐sample questionnaire study design is used following the STROBE checklist. Methods The inter‐rectus distance was measured by computed tomography in 644 women. Custom questionnaires, the Oswestry Disability Index, The International Consultation on Incontinence Questionnaire‐Urinary Incontinence Short Form and the Medical Outcomes Study 36‐Item Short Form Health Survey (SF‐36) were used to investigate personal information, the subjects’ back pain, pelvic floor function and quality of life, respectively. Results The incidence of DRA was 28.4%. Age, the number of pregnancies, BMI and diabetes were influencing factors for DRA. After age stratification, pregnancy and diabetes were found to be risk factors for DRA in young women, and obesity and diabetes were risk factors for DRA in older women. This study showed that the association between DRA and low back pain was highly significant. Conclusions Diastasis recti abdominis is common in adult women. Avoiding multiple pregnancies, preventing diabetes and controlling weight may prevent DRA, which may be beneficial for decreasing low back pain in women. Relevance to clinical practice The findings have important implications for the health of adult women which can provide the basis for appropriate nursing implementation for DRA patients. The application of specific prevention and intervention measures for the risk factors may reduce the severity of low back pain.

BackgroundHeavy menstrual bleeding (HMB) has been shown to have a profound negative impact on women’s quality of life and lead to increases in health care costs; however, data on HMB among Chinese population is still rather limited. The present study therefore aimed to determine the current prevalence and risk factors of subjectively experienced HMB in a community sample of Chinese reproductive-age women, and to evaluate its effect on daily life.MethodsWe conducted a questionnaire survey in 2356 women aged 18–50 years living in Beijing, China, from October 2014–July 2015. A multivariate logistic regression model was used to identify risk factors for HMB.ResultsOverall, 429 women experienced HMB, giving a prevalence of 18.2%. Risk factors associated with HMB included uterine fibroids (adjusted odds ratio [OR] =2.12, 95% confidence interval [CI] = 1.42–3.16, P < 0.001) and multiple abortions (≥3) (adjusted OR = 3.44, 95% CI = 1.82–6.49, P < 0.001). Moreover, women in the younger age groups (≤24 and 25–29 years) showed higher risks for HMB, and those who drink regularly were more likely to report heavy periods compared with never drinkers (adjusted OR = 2.78, 95% CI = 1.20–6.46, P = 0.017). In general, women experiencing HMB felt more practical discomforts and limited life activities while only 81 (18.9%) of them had sought health care for their heavy bleeding.ConclusionsHMB was highly prevalent among Chinese women and those reporting heavy periods suffered from greater menstrual interference with daily lives. More information and health education programs are urgently needed to raise awareness of the consequences of HMB, encourage women to seek medical assistance and thus improve their quality of life.Electronic supplementary materialThe online version of this article (10.1186/s12905-019-0726-1) contains supplementary material, which is available to authorized users.

Numerous empirical studies have been carried out to explore factors of online health management continuance. However, results were not unified. We thus conducted a meta-analysis to identify influential factors and potential moderators. A systematic literature search was performed in nine databases (PubMed, Web of Science, the Cochrane Library, Ovid of JBI, CINAHL, Embase, CNKI, VIP, and CBM) published up to December 2020 in the English or Chinese language. Meta-analysis of combined effect size, heterogeneity, moderator analysis, publication bias assessment, and inter-rater reliability was conducted. Totally 41 studies and 12 pairwise relationships were identified. Confirmation, perceived usefulness, satisfaction, information quality, service quality, perceived ease of use, and trust were all critical predictors. Service type and age difference showed their moderating effects respectively. The perceived usefulness was more noteworthy in medical service than health and fitness service. The trust was more noteworthy in young adults. The results confirmed the validity and robustness of the Expectation Confirmation Model, Information Systems Success Model, and trust theory in online health management continuance. Moderators included but are not limited to age difference and service type. The elderly research in the healthcare context and other analytical methods such as qualitative comparative analysis should be applied in the future.

BackgroundMost insulin injections for people with diabetes are administered at home, thus generating many used needles. Unsafe disposal of these at-home needles can lead to needle stick injuries, blood-borne disease transmission, and environmental contamination. Previous studies have shown varying results on the prevalence of and factors associated with safe sharps disposal practices of people with diabetes.ObjectiveTo assess the prevalence of and the factors associated with the safe disposal of used insulin needles among patients with diabetes.MethodsWe collected data from 271 insulin-using patients at a tertiary care hospital in China. A self-designed instrument was used to assess sociodemographic data, disease- and treatment-related characteristics, sharps disposal practices, education on diabetes self-management and sharps disposal, and awareness of the potential risks associated with unsafe sharps disposal. Multivariate logistic regression analysis was used to explore factors associated with safe sharps disposal practices.ResultsOnly 10.3% (28/271) of participants disposed of used at-home insulin needles in a safe manner, and 14.8% (45/271) of participants had received previous instruction on sharps disposal. Previous sharps disposal instruction (AOR = 4.143, 95% CI = 1.642–10.450) and awareness of the risk of blood-borne pathogen transmission (AOR = 3.064, 95% CI = 1.332–7.046) were associated with safe disposal of used insulin needles.ConclusionIn our study, the prevalence of safe sharps disposal practices was low, and a minority of respondents had received previous instruction on sharps disposal. Participants who had previously received instruction and were aware of the risk of blood-borne pathogen transmission were more likely to handle sharps safely. Our study findings suggest that health care professionals should pay attention to sharps disposal practices of patients with diabetes and conduct diabetes education programs that include information on safe sharps disposal methods and potential hazards of unsafe sharps disposal.
