BACKGROUND: Without timely and effective rehabilitation, hearing loss may profoundly affect human life quality. China has a large population of hearing-impaired individuals, which imposes a heavy health burden on society. Moreover, this population is projected to increase rapidly owing to China's aging society. METHODS: We used data from a population-representative epidemiological investigation of hearing loss and ear diseases in four Chinese provinces. We estimated the national prevalence using multiple linear regression of the age-group proportions and prevalence in 31 provinces with clustering analysis. We used years lived with disability (YLDs) to analyze the disease burden and forecasted the prevalence of hearing loss by 2060 in China. RESULTS: An estimated 115 million people had moderate-to-complete hearing loss in 2015 across the 31 provinces of China (8.4% of 1.37 billion people). Of these, 85.7% were older than age 50 years (99 million people) and 2.4% were younger than 20 years old (2.8 million people). Of all YLDs attributable to hearing loss, 68.9% were attributable to moderate-to-complete cases. By 2060, a projected 242 million people in China will have moderate-to-complete hearing loss, a 110.0% increase from 2015. CONCLUSIONS The hearing loss prevalence in China is high. Population aging and socioeconomic factors substantially affect the prevalence and severity of hearing loss and the disease burden. The prevalence and severity of hearing loss are unevenly distributed across different provinces. Future public health policies should take these trends and regional variations into account.

Acute ischemic stroke (AIS) is a cerebrovascular disease characterized by high morbidity, disability, and mortality, posing a significant threat to human health. Endovascular treatment has now been established as a key method for AIS management, in which stent retrievers that can mechanically remove blood clots play a key role in this technique. In recent years, stent retrievers have evolved in complexity and functionality to improve the ability of clot removing and surgical safety. However, the present instruments still have limitations on treatment efficiency, vascular adaptability, and operational precision, posing an urgent need for innovation in the design of stent retrievers. This paper systematically reviewed the structural features and working principles of AIS stent retrievers from the perspective of efficacy evaluation metrics, historical development, recent advancements in stent retrieval technology, and future prospects.

Objective:To understand the current situation and demand of intracavity electrocardiographic positioning technique training for PICC specialist nurses in Shandong Province, and provide a reference for further improving and improving the training of PICC specialist nurses.Methods:From July 7-23, 2019, a total of 903 PICC specialist nurses in Shandong Province were selected by the convenience sampling method. The nurses were investigated by the self-made general information questionnaire of PICC specialist nurses in Shandong Province and the training demand questionnaire of intracavity electrocardiographic positioning technique.Results:40.75% (368/903) PICC specialist nurses had participated in intracavity electrocardiographic positioning technique training; 84.27% (761/903) PICC specialist nurses thought it necessary to conduct intracavity electrocardiographic positioning technique training. PICC specialist nurses had various training on intracavity electrocardiographic positioning technique, the average content requirements were all above 4.67 points. The highest score of theoretical training content was the judgment of the relationship between catheter tip position and electrocardiogram P wave (4.80 ± 0.47), and the highest score of operation training content was the intracavitary electrocardiography guided PICC catheterization (4.74 ± 0.55). 94.24%(851/903) PICC specialist nurses hoped to achieve the goal of improving clinical nursing practice ability through intracavity electrocardiographic positioning technique training. Intravenous therapy specialist academic conference was the main hoped training form(76.85%, 694/903). Multiple regression analysis showed that the number of years of catheterization, job position and understanding of the technology were the influencing factors of PICC specialist nurses′ training needs for intracavity electrocardiographic positioning technique ( t = -3.73,3.12, -3.63, all P<0.05). Conclusions:The training rate of intracavity electrocardiographic positioning technique was low, but PICC specialist nurses had higher training requirements for intracavity electrocardiographic positioning technique. Managers should pay attention to the training of intracavity electrocardiographic positioning technique, and develop targeted training programs to further improve the clinical practice capabilities of the PICC specialist nursing team.

Objective:To investigate the status quo of a mobile nursing application acceptance of nurses, and analyze the influencing factors, so as to promote the application of a mobile nursing APP in clinic.Methods:On the principle of convenience sampling, 1207 participants from Shandong province were recruited to complete the self-designed questionnaire, including demographic data, smartphone use behavior and acceptance evaluation of the mobile nursing APP.Results:Average score of nurses' acceptance of a mobile nursing APP was 4.16±0.69. Multiple regression results showed that duty, use experience, recognition, smartphone self-efficacy and daily use time were the main factors affecting the acceptance of a mobile nursing APP for nurses ( t value was -7.132-22.678, P<0.05 or 0.01) and explained 39.1% of the total variation of the acceptance of mobile nursing app ( P<0.01). Conclusions:The acceptability of mobile nursing APP of clinical nurses is at a medium and high level, and it is influenced by the use experience, smartphone self-efficacy and other aspects, suggesting that nursing managers attach importance to the behavioral differences of nurses in using a mobile nursing APP.

Objective: To explore the real experience of functional exercise after PICC operation. Methods: Phenomenological methods were used to conduct semi-structured interviews with 15 patients who had different functional exercises after PICC. Colaizzi phenomenological analysis was used to analyze the data. Results: Through interviews, four themes were drawn: the exercise characteristics of different postoperative functional exercise, the benefits of postoperative functional exercise, the obstacles to postoperative functional exercise and the suggestions for education related to postoperative functional exercise. Conclusion The patients with PICC think that the postoperative functional exercise is safe and practical, but the recognition and compliance of the postoperative functional exercise are still limited. It is suggested that appropriate training should be carried out among medical staff, so as to rationally select the way of postoperative functional exercise, further promote the application of postoperative functional exercise, and improve the compliance and experience of patients.

Objective:To understand the practice status of intracavitary electrocardiography (ECG) -guided peripherally inserted central catheter (PICC) placement in Shandong Province, so as to provide a reference for promoting the application of intracavitary ECG positioning technology, carrying out systematic training and formulating standardized intracavitary ECG-guided PICC placement procedures.Methods:From July to August 2019, convenience sampling was used to select 1 034 PICC specialist nurses from 258 hospitals in Shandong Province as the research object. The self-designed questionnaire Survey Questionnaire on the Practice Status Quo of Intracavitary ECG-guided PICC Placement in Shandong Province was used to investigate the practice status of the intracavitary ECG-guided PICC placement by PICC specialist nurses in Shandong Province. A total of 1 034 questionnaires were returned, and 903 valid questionnaires were collected, with a valid rate of 87.33%.Results:Among the 903 PICC specialist nurses, 835 (92.47%) of the nurses had learned about the intracavitary ECG-guided PICC placement, 368 (40.75%) had participated in the training of intracavitary ECG-guided PICC placement, and only 363 (40.20%) had used intracavitary ECG-guided PICC placement. Among 363 nurses who had used intracavitary ECG-guided PICC placement, 93.66% (340/363) evaluated the patient's body surface electrocardiogram before puncture, and 49.31% (179/363) believed that PICC was delivered when P wave was the highest, and the catheter was retreated when P wave appeared negative until the negative wave just disappear; 91.18% (331/363) thought that chest radiographs must be taken to locate the catheter tip after the application of intracavitary ECG-guided PICC placement.Conclusions:At present, the training, promotion and application of intracavitary ECG-guided PICC placement needs to be strengthened. There is an urgent need to develop a unified and standardized operation process for intracavitary ECG-guided PICC placement to improve the scientific and standardization of this application.

Objective? To understand the work experience of PICC nurse specialists in using intracavitary electrocardiogram for PICC placement, so as to provide a reference for further promoting and standardizing of the intracavitary electrocardiogram method. Methods? From October 2018 to February 2019, the PICC nurse specialists from 5 Class Two and 16 Class Three hospitals which developed intracavitary electrocardiogram guided PICC in Shandong Province were selected by purposive sampling method as interveiwees. A qualitative phenomenological study was used to conduct semi-structured interviews with 21 PICC specialist nurses. Colaizzi's seven-step analysis method was used to analyze the data. Results? Three themes were identified:a method that "makes your mind at rest", difficulties met in work, growth and learn. The intracavitary electrocardiogram method effectively promoted PICC placement and released pressure of nurse specialists. Nurse practitioners will experience hardship at the beginning of using the intracavitary electrocardiogram method. As they gradually became skilled and came across difficulties, they would experience development personally and professionally. Conclusions? The intracavitary electrocardiogram method can benefit PICC nurse specialists both in their profession and career identity. However, the PICC nurse will face difficulties from different aspects while using this method. It is necessary to support better training courses and standardized management for the extension of intracavitary electrocardiogram method, promoting the promotion and application of new technologies.
