Objective To understand the status quo of job embeddedness and turnover intention of hospital nurses,and to explore their correlation.Methods Using convenient sampling method,we selected 538 nursing workers from 8 tertiary hospi-tals in Guangzhou,and conducted an electronic questionnaire survey with job embeddedness Scale and Turnover Intention Scale.Results The total average score of job embeddedness was(3.41±1.26),and the total average score of turnover intention was(2.66±0.94).There was a negative correlation between job embeddedness and turnover intention(r =-0.060,P＞0.05).Conclusion The scores of job embeddedness and turnover intention of hospital nurses are at the middle level,and job embed-dedness is negatively correlated with the total average score of turnover intention.It is suggested that the management mode of hospital nurses should be standardized,the legitimate rights and interests of nurses should be guaranteed,the construction of pro-fessional certification system should be promoted,the nurses'positive job embeddedness should be promoted,the hospital nurs-ing staff should be stabilized,and the satisfaction of nursing service should be improved.

Objective:To investigate the correlation among physical activity,mild depressive symptoms and frontal alpha power asymmetry in college students.Methods:Seventy college students with mild depressive symp-toms who conformed to the standard of the Self-Rating Scale for Depression(SDS)of 53-62 and 70 normal col-lege students were recruited.The frontal alpha power was measured under quiet and closed-eye state,and the total physical activity(PA)was assessed with the International Physical Activity Questionnaire.Results:The college students with mild depressive symptoms had lower Total PA scores,right frontal alpha power and frontal alpha a-symmetry(FAA)than the normal controls(P＜0.001).In college students with mild depressive symptoms,the to-tal PA scores(r=-0.29,P＜0.05)and FAA(r=-0.41,P＜0.001)were negatively correlated with SDS scores,and the total PA scores were positively correlated with FAA(r=0.34,P＜0.01).Conclusion:The college students with mild depressive symptoms may have reduced physical activity and asymmetric right lateralization of frontal alpha power.There is a correlation among depressive symptoms,physical activity and frontal alpha power a-symmetry in college students with mild depressive symptoms.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

Objective To examine the current state of care services for geriatric osteoporotic fractures in Chinese hospitals and to provide a basis for the improvement of these services and the formulation of related policies.Methods In September to November 2023,a stratified convenience sampling method was used to investigate the implementation of care services for elderly patients with osteoporotic fractures in 621 hospitals across 31 provinces(autonomous regions and municipalities)in China.A self-designed questionnaire was utilized for this purpose.Results A total of 621 hospitals participated in the survey,with 432(69.57%)tertiary hospitals and 189(30.43%)secondary hospitals.Over 95%of hospitals provided health education on diet,medication,fall prevention,and early functional exercise for elderly fracture patients.Less than 80%of hospitals provide specialized training on osteoporosis treatment and secondary fracture prevention for medical staff.Only 263 hospitals(42.35%)routinely conduct bone density tests for patients over 50 years old with fractures,while 221 hospitals(35.59%)routinely conduct bone metabolic biochemical tests for such patients.Less than 50%of hospitals provide specialized services,such as geriatric osteoporotic fracture clinics,for elderly patients with osteoporotic fractures.Additionally,39.77%of hospital departments have not developed postoperative care plans for elderly patients with osteoporotic fractures.The lack of specialized care teams(91.63%),insufficient investment in care resources(88.08%),and the absence of policy support(77.45%)are identified as the primary factors impeding the provision of care services for elderly patients with osteoporotic fractures in hospitals.Although some care services in tertiary hospitals are superior to those in secondary hospitals(P<0.05),they are still far from adequate.Conclusion The development of care services for elderly patients with osteoporotic fractures in Chinese hospitals needs improvement.It is recommended to further standardize and enhance the content and methods of health education,intensify clinical assessments related to osteoporosis in elderly fracture patients,improve the professional care capabilities of medical staff,and at the same time,the state should introduce relevant policies to support and promote the construction and development of hospital care services for elderly osteoporotic fracture patients.

Objective:To explore the influencing factors and effectiveness of community follow-up in patients with cardiac implantable electronic device (CIED) implantation.Method:A total of 132 patients who received CIED implantation in the Department of Cardiology of Tongren Hospital, Shanghai Jiao Tong University School of Medicine from February 2021 to February 2022 were enrolled in this prospective cohort study. Among them 33 patients were followed up in community health service centers associated with Tongren Hospital (community follow-up group) and 99 matched patients were followed up in the CIED outpatient clinic of the hospital (outpatient follow-up group) with a ratio of 1∶3. The clinical data of the selected patients were collected through a questionnaire survey; the follow-up data were extracted through the CarelinkExpress electronic follow-up platform and the CIED outpatient information system of Tongren Hospital. Adjustment of the treatment protocol or CIED parameters at follow-up, and the referral from the community health service centers were defined as visit with-an-action (VWA). The endpoint of follow-up was the occurrence of major adverse events. The multivariate logistic regression model was used to analyze the factors influencing patient selection for community follow-up.Results:The univariate analysis showed that the frequency of visits to community health service centers and the service contracting rate in community follow-up group were higher than those of outpatient follow-up group ( P<0.05). The multivariate logistic regression analysis showed that the contracted community physician service was an independent influencing factor of patient choosing community follow-up ( OR=2.143, 95% CI: 1.103-4.166, P=0.025). A total of 469 visits of followed up occurred in 132 patients, including 45 community visits and 424 outpatient visits. VWA accounted for 22.2% (10/45) in the community follow-up group, and 17.2% (73/424) in the outpatient follow-up group ( P>0.05). There was no significant difference in the safety and effectiveness indicators (VWA, major adverse events, and unplanned follow-up) between the two groups ( P>0.05). More patients in the community follow-up group walked to the hospital than the outpatient follow-up group ( P<0.05);and the main transportation for the later was by bus or taxi(42(42.4%)or 41(41.4%)). The average waiting time in the community follow-up group was significantly shorter than that in outpatient follow-up group ( P<0.05). The total time required for a single follow-up in the community follow-up group was 50.0 (45.0, 59.5) minutes, which was significantly shorter than that in the routine outpatient follow-up group (107.0 (90.0, 135.0) minutes, P<0.05). Conclusions:The contracting with community physicians is an independent influencing factor for CIED implanted patients to choose community follow-up. The safety and effectiveness of community follow-up are comparable to routine outpatient follow-up, and community follow-up is more convenient.

Objective:To analyze the changes of peripheral perfusion index (PPI) with late-onset sepsis (LOS) in very low birth weight infants during hospitalization.Methods:Very low birth weight infants admitted to the neonatal intensive care unit of Children′s Hospital of Fudan University from August 1, 2021 to August 31, 2022 were consecutively included.Infants with admission age ≥three days and unstable circulation, or positive blood culture within three days after birth were excluded.From the day of admission, the PPI values of the right hand and either foot of the infants were measured with Masimo SET Radical-7 everyday while whether LOS occurred during hospitalization was observed.The mean PPI curve of very and extremely low birth weight infants without LOS was plotted.For those with LOS confirmed by blood culture, the PPI change trajectory three days before and after the occurrence of LOS was drawn, and the change trend of PPI before the occurrence of LOS was analyzed by trend chi-square test.Non-parametric test was used to analyze the effect of LOS on pre- and post-ductal PPI values.Results:A total of 107 very low birth weight infants were included in the final analysis.Among them, there were 11 infants confirmed as LOS by blood culture, 37 infants diagnosed as clinical LOS, and 59 infants without LOS.Pre-and post-ductal PPI values of very low birth weight infants without LOS were 2.06±1.30 and 1.72±0.92, respectively; those with clinical LOS were 1.90±0.94 and 1.58±0.83, respectively; those with LOS confirmed by blood culture were 1.92±1.11 and 1.62±0.82, respectively.For infants with LOS confirmed by blood culture, the pre-and post-ductal PPI values showed a continuous downward trend during three days before the onset of disease, with the lowest PPI values on the first day before the diagnosis of blood culture.The downtrend of pre-ductal PPI was statistically significant ( χtrend2=5.57, P<0.05). Conclusion:The PPI value of very low birth weight infants show a downward trend when LOS occurs.It should be observed dynamically in clinical practice, which is helpful to suspect or identify LOS as early as possible.

Objective:To analyze the fail mode of neoadjuvant therapy combined with surgery for locally advanced esophageal squamous cell carcinoma (ESCC) after long-term follow-up.Methods:Clinical data of consecutive 238 patients with locally advanced resectable ESCC who underwent neoadjuvant therapy combined with surgery in Zhejiang Cancer Hospital from September 2012 to October 2019 were retrospectively analyzed. The failure mode in the whole cohort was analyzed after long-term follow-up. The overall survival (OS) and disease free survival (DFS) rates were analyzed by Kaplan-Meier method. Survival differences were determined by log-rank test.Results:The pathological complete response (pCR) rate was 42.0% in 238 patients. After a median follow-up of 46.1 months, tumor progression occurred in 96 patients (40.3%), including 25 patients (10.5%) with local recurrence, 61 patients (25.6%) with distant metastases, and 10 patients (4.2%) with simultaneous local recurrence and distant metastases. The median OS and DFS were 64.7 months and 49.9 months. And the 3-, 5-, and 7-year OS and DFS rates were 70.0%, 52.8%, 36.4% and 63.5%, 42.5%, and 30.0%, respectively. The 3-, 5-, and 7-year locoregional recurrence-free survival rates and distant metastasis-free survival rates were 86.0%, 71.4%, 61.2% and 70.6%, 55.9%, 43.0%. Compared with non-pCR patients, the overall progression rate and distant metastasis rate of pCR patients were lower (26.0% vs. 50.7%, 16.0% vs. 32.6%, both P<0.05). And the 3-, 5-, and 7-year OS (83.0% vs. 60.2%, 69.7% vs. 41.7%, 50.4% vs. 27.7%, all P<0.001) and DFS rates (80.4% vs. 51.4%, 63.9% vs. 31.2%, 45.9% vs. 20.3%, all P<0.001) were significantly better in pCR patients. Conclusions:Distant metastasis is the main failure mode of patients with locally advanced ESCC after neoadjuvant therapy. Patients with postoperative pCR can achieve better long-term survival.

Objective:To explore the types of venous access, indwelling time and the correlation with catheter-related bloodstream infection (CRBSI) of very and extremely low birth weight infants (VLBW & ELBW) in NICU.Methods:The self-designed venous access data collection form was used to collect the venous access data of VLBW & ELBW infants who were admitted to NICU of Children′s Hospital of Fudan University from January to December 2019. SPSS 22.0 software was used for data analysis, description and binary Logistic regression analysis.Results:A total of 218 cases were collected, including 9 cases of peripheral intravenous (PIV), 30 cases of PIV+ umbilical vein catheter (UVC), 43 cases of PIV+PICC, 136 cases of PIV+UVC+PICC. The average indwelling time of UVC was 6 days, the average indwelling time of PICC was 22 days. There were 23 cases (10.55%) got CRBSI and 195 cases (89.45%) without CRBSI. Binary Logistic regression analysis showed that birth weight ( OR=1.003, 95% CI 1.000-1.006, P<0.05) and combination form of venous access ( OR=0.139, 95% CI 0.023-0.834, P<0.05) of VLBW & ELBW infants were associated with CRBSI. Conclusions:In NICU, PIV, UVC and PICC are the three main ways to indwell venous access for VLBW & ELBW infants. The occurrence of CRBSI is closely related to the type and combination of indwelling venous access.

Objective:To analyze the diagnosis and treatment process of a kala-azar case with prominent renal damage treated with liposomal amphotericin B (L-AmB), and to provide theoretical basis for clinical diagnosis and treatment.Methods:A retrospective analysis method was used to analyze the clinical data, diagnosis and treatment process and laboratory test results of a case of kala-azar with prominent renal damage who presented to the Department of Infectious Diseases, The First Affiliated Hospital of Xi'an Jiaotong University on June 30, 2020.Results:A 56-year-old female patient presented with fever (the highest body temperature was 38.2 ℃) and chills. The results of clinical laboratory tests showed that hemoglobin(55 g/L), red blood cell (2.68 × 10 12/L), white blood cell (1.06 × 10 9/L) and platelet count (8.00 × 10 9/L) were decreased, renal function showed abnormal blood urea nitrogen and creatinine, spleen enlargement, etc., and the diagnosis of kala-azar combined with kidney insufficiency was confirmed by blood and bone marrow Leishmania spp. examination. With the assistance of continuous renal replacement therapy (CRRT), after a small dose of L-AmB was initially and slowly increased and maintained at a low dose, the patient's body temperature was normal, the blood routine showed that the three-lineage cells gradually increased, and the renal function showed blood urea nitrogen and creatinine decreased gradually the spleen was retracted; no recurrence was found at follow-up after 6 months, and renal function returned to normal. Conclusions:L-AmB is safe and effective in the treatment of kala-azar with renal damage as the prominent manifestation. The patient is not only cured by etiology, but is also recovered renal function.

Objective:To investigate the occurrence of carotid artery abnormalities in human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients and the related risk factors affecting the occurrence of carotid artery abnormalities.Methods:A total of 169 regular follow-up outpatients with HIV/AIDS from April 2003 to December 2019 in Peking Union Medical College Hospital, whose carotid artery ultrasound examination were performed from July 2015 to December 2019 were included. The patients were divided into young (≤44 years old), middle-aged and elderly (≥45 years old) according to their ages, and the physical examination data of the included patients were collected.The statistical methods were logistic regression analysis and single sample t test. Results:Among the 169 HIV/AIDS patients, 40(23.7%) had abnormal carotid artery and 129(76.3%) had no abnormal carotid artery. Middle-aged and elderly people (odds ratio ( OR)=3.85, 95%confidence interval (95% CI) 1.54-9.65, P<0.01), hypertension ( OR=6.24, 95% CI 1.95-20.00, P<0.01), hyperlipidemia ( OR=2.44, 95% CI 1.00-5.93, P<0.05), and elevated human leucocyte antigen (HLA)-DR + CD8 + /CD8 + ( OR=1.03, 95% CI 1.01-1.06, P<0.05) were the risk factors for carotid artery abnormality. The common carotid artery inner medium film thickness (IMT) of patients in HIV/AIDS group Ⅰ (20 to 30 years old), group Ⅱ (31 to 40 years old), group Ⅲ (41 to 50 years old) were (0.061 0±0.001 2), (0.062 9±0.001 4) and (0.065 6±0.002 6) cm, respectively, which were thicker than the control groups ((0.051±0.003), (0.056±0.004) and (0.063±0.002) cm, respectively). The differences were all statistically significant ( t=5.119, 4.775 and 1.739, respectively, all P<0.05). The common carotid artery IMT of patients in HIV/AIDS group A (30 to 44 years old) and group B (45 to 59 years old) were (0.062 6±0.001 1) and (0.072 3±0.003 4) cm, respectively, which were thicker than the control groups ((0.052±0.011) and (0.064±0.015) cm, respectively), the differences were both statistically significant ( t=9.520 and 3.012, respectively, both P<0.01). Conclusion:Younger HIV-positive people have a higher probability of abnormal carotid arteries and may be at greater risk of cardiovascular disease than HIV-negative people of the same age, suggesting that HIV-positive people, especially young people, should be examined early with ultrasound of the neck arteries to detect abnormalities and intervene as soon as possible.
