Objective:To deeply explore the thematic needs and characteristics of learners regarding course elements based on the review texts of nursing massive open online courses (MOOC), providing a reference for achieving effective alignment between digital nursing education content and learner needs.Methods:Data were collected from the review texts of 112 nursing courses on the Chinese University MOOC platform using a web crawler script written with Python′s Requests library. The collection period spanned from the course launch dates to December 31, 2023. Sentiment analysis and high-frequency words analysis were conducted using Chinese text Nature language processing library, and core themes of learners′ positive and negative reviews were extracted using the latent dirichlet allocation.Results:A corpus of 18 184 nursing MOOC review texts was constructed, with positive sentiment reviews accounting for 89.30% (16 238/18 184) and negative sentiment reviews making up 10.70% (1 946/18 184). Word frequency analysis revealed that most nursing MOOC serve as carriers for blended online and offline teaching models, with students being the primary target audience, though social participants were also involved. The reviews effectively mirrored real-world clinical nursing scenarios. The need of learners was categorized into three major themes: content design and assessment, course resources and teaching strategies, and software applications and platform functionality.Conclusions:This study, leveraging text mining technology, thoroughly investigated the three thematic characteristics of nursing MOOC needs of online learners and proposed targeted optimization recommendations. Future research could incorporate other online teaching platforms and comprehensively construct a sentiment lexicon for nursing online course reviews using big data modeling and machine learning algorithms. These would enable a holistic analysis of the digital nursing education landscape, allowing for precise improvements to address existing shortcomings.

OBJECTIVE Explore the influencing factors of hearing loss among workers exposed to noise.METHODS A total of 167 noise exposure practitioners undergoing hearing testing in Hangzhou Occupational Disease Prevention and Treatment Center from January 2022 to December 2023 were selected to perform hearing testing on the left and right ears of the patients.Based on the test results,the patients were divided into 123 hearing loss patients(loss group)and 44 non hearing loss patients(control group).The population characteristics,laboratory indicators,noise exposure,and other indicators of the two groups were compared.Logistic regression models were used to analyze the risk factors for hearing loss in noise exposed workers.RESULTS In the 2 000,3 000,4 000,and 6 000 Hz air conduction hearing threshold tests,the hearing threshold of the right side of the loss group patients was higher than that of the control group.In the 500,1 000,2 000,3 000,4 000,and 6 000 Hz air conduction hearing threshold tests,the hearing threshold of the left side of the loss group patients was higher than that of the control group,and the differences were statistically significant(P<0.05).The age of patients in the loss group,the proportion of patients with concurrent chronic diseases,and the proportion of patients with junior high school education or below were all significantly different from those in the control group,and the differences were statistically significant(P<0.05).The length of service and the proportion of patients with liver function loss in the loss group were significantly higher than those in the control group.The proportion of noise protection patients and those who frequently use noise protection equipment in the loss group were significantly lower than those in the control group,and the differences were statistically significant(P<0.05).The results of the Logistic regression model showed that older age,comorbidities with chronic diseases,longer working experience,lack of noise protection,and occasional or never use of noise protection equipment were independent risk factors for hearing loss in noise exposed workers(P<0.05).CONCLUSION There are many factors that can affect the occurrence of hearing loss among workers exposed to noise.Targeted preventive interventions based on high-risk factors can reduce the risk of hearing loss in the population.

OBJECTIVES: Pelvic floor dysfunction is common among pregnant and postpartum women and significantly impacts quality of life. This study aims to translate the German Pelvic Floor Questionnaire for Pregnant and Postpartum Women into Chinese and to evaluate its reliability and validity in the Chinese population. METHODS: The questionnaire was translated using the Brislin model. A cross-sectional study was conducted among pregnant and postpartum women to assess the content validity, construct validity, Cronbach's α coefficient, test-retest reliability, and split-half reliability of the Chinese version. RESULTS: A total of 72 women were included, with 6.9% being pregnant and 93.1% postpartum; the age was (32.3±3.6) years. The Chinese version of the questionnaire contains 4 dimensions and 45 items. The content validity index of individual items ranged from 0.833 to 1.000, with a scale-level content validity index of 0.977 and intraclass correlation coefficients (ICCs) exceeding 0.90. The overall Cronbach's α coefficient was 0.891, with subscale coefficients ranging from 0.732 to 0.884 (all ICCs>0.70). The test-retest reliability of the total scale was 0.833, and for the 4 dimensions, bladder, bowel, prolapse, and sexual function, the values were 0.776, 0.579, 0.732, and 0.645, respectively. The split-half reliability was 0.74. CONCLUSIONS The Chinese version of the questionnaire demonstrated good reliability and validity, indicating its applicability in assessing pelvic floor dysfunction and associated risk factors during pregnancy and postpartum.

Objective:To comprehensively search the relevant literature on prone position-cardiopulmonary resuscitation (PP-CPR) in adults at home and abroad, analyze the content, summarize the evidence, and provide reference for clinical health care professionals.Methods:Systematic search of CNKI, China Biomedical Literature Service System (SinoMed), Wanfang Data, VIP database, PubMed, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochran Library, Web of Science, Scopus literature database and other Chinese and English databases was conducted. The search period was from inception to June 15 in 2024. The contents of PP-CPR from randomized controlled trial (RCT), non-RCT (prospective or retrospective), cohort studies and case reports were extracted and systematically analyzed. The search results were standardized by the method of scoping review.Results:A total of 523 articles were obtained through preliminary search, and 14 references and gray literature were retrieved, totaling 537 articles. After strict screening by two researchers, a total of 26 literatures were included, 3 were non-RCT and 23 were case reports, involving 12 countries, including 3 in Chinese, 19 in English, 2 in French, 1 in German, and 1 in Korean. Three non-RCT demonstrated that compared with standard cardiopulmonary resuscitation (CPR), PP-CPR could produce higher pressure, and provide good respiratory and circulatory support. A total of 25 adult patients were included in the 23 case reports, of which 17 reported total recovery time and 13 reported PP-CPR time ≤ 5 minutes, all of which recovered spontaneous circulation, indicating the effectiveness of PP-CPR technology. In terms of final outcome, 4 patients (16.0%) died and 21 patients (84.0%) survived, indicating that PP-CPR technology could provide timely blood circulation and improve clinical outcomes for prone cardiac arrest patients. Among the 11 patients who reported complications after resuscitation, no neurological damage was found in the short-term outcomes, indicating that PP-CPR technology had a certain level of safety.Conclusions:PP-CPR can provide timely blood circulation for patients with cardiac arrest who are unable to lie supine quickly, and win "golden time" for defibrillation and further treatment. In clinical practice, medical staff need to evaluate the emergency environment, the number of rescuers and the specific condition of the patient, and implement first aid as soon as possible, so as to reduce the time of no blood flow in the vital organs of patients with cardiac arrest in prone position, and improve the clinical prognosis.

OBJECTIVES: Pelvic organ prolapse (POP) is a common condition in postmenopausal women, with an increasing prevalence due to aging. Some women experience POP recurrence after surgical treatment, significantly affecting their physical and mental health. The uterosacral ligament is a critical pelvic support structure. This study aims to investigate the molecular pathological changes in the uterosacral ligament of postmenopausal women with recurrent POP using transcriptomic analysis. METHODS: Transcriptomic data of uterosacral ligament tissues were obtained from the public dataset GSE28660, which includes samples from 4 postmenopausal women with recurrent POP, 4 with primary POP, and 4 without POP. Differentially expressed genes (DEGs) were identified between recurrent POP and both primary and non-POP groups. Further analysis included intersection analysis of DEGs, gene ontology enrichment, protein-protein interaction (PPI) network construction, gene set enrichment analysis (GSEA), single-sample GSEA, and xCell immune cell infiltration analysis to explore molecular pathological changes in recurrent POP. Additionally, histological and molecular differences in the uterosacral ligament were compared between simulated vaginal delivery (SVD) rat models with and without ovariectomy. RESULTS: Compared with primary POP and non-POP groups, recurrent POP exhibited activation of adipogenesis and inflammation-related pathways, while pathways related to muscle proliferation and contraction were downregulated in the uterosacral ligament. Nine key DEGs (ADIPOQ, FABP4, IL-6, LIPE, LPL, PCK1, PLIN1, PPARG, and CD36) were identified, with most enriched in the peroxisome proliferator-activated receptor (PPAR) signaling pathway. These genes were significantly correlated with lipid accumulation, monocyte infiltration, and neutrophil infiltration in the uterosacral ligament. Urodynamic testing revealed that the bladder leak point pressure was significantly higher in ovariectomized SVD rats, both of which had higher values than the sham group. Masson staining showed pronounced adipogenesis in the uterosacral ligament of ovariectomized SVD rats, along with reduced collagen and muscle fibers compared to the sham and non-ovariectomized SVD groups. Furthermore, real-time RT-PCR confirmed significantly elevated expression of key DEGs, including ADIPOQ, IL-6, PCK1, and PLIN1, in the uterosacral ligaments of ovariectomized SVD rats. CONCLUSIONS Adipogenesis and inflammation in the uterosacral ligament may contribute to its reduced supportive function, potentially leading to recurrence POP in postmenopausal women.

OBJECTIVES: Pelvic floor sensory training is commonly used in clinical practice for the treatment of stress urinary incontinence (SUI); however, there is a lack of comparative studies evaluating pelvic floor sensation between women with SUI and healthy controls. Additionally, normative data for two-point discrimination thresholds in the female pelvic floor region remain scarce. This study aims to compare the results of 4 sensory tests in the pelvic floor region between women with mild SUI and healthy women, in order to provide reference values for two-point discrimination thresholds in this area. METHODS: From April 1 to October 30, 2023, 108 healthy women [(32.5±3.6) years] and 90 women with mild SUI [(32.9±3.3) years] were recruited from the Third Xiangya Hospital, Central South University. Participants underwent 4 sensory tests in the pelvic floor region: Two-dot discrimination, weight perception, shape recognition, and 9-grid localization. The results were compared between the 2 groups. RESULTS: Compared with healthy women, those with mild SUI had lower sensitivity and higher thresholds in 2-dot discrimination tests in the pelvic floor region (all P<0.001). No significant differences were found between groups in weight perception, shape recognition, or grid localization tests (P>0.05). CONCLUSIONS Women with mild stress urinary incontinence have impaired two-point discrimination ability in the pelvic floor region.
