“Integrated elderly care and medical services” is a new model of elderly care that relies on medical care as a guarantee， rehabilitation as a support， and combines ongoing medical treatment with nurturing， offering comprehensive therapy. This new type of elderly care model also poses new job requirements for elderly care workers. However， there is currently a large shortage of elderly care workers， along with prevalent issues such as low professional quality， low education level， and an older average age. The main reasons for this situation are low welfare benefits， low social status， and an incomplete promotion system in the industry， resulting in low social recognition of the industry， a shortage of employees， and a high number of resignations. Based on this， it is suggested to expand the number of the elderly care team and enhance the quality of the elderly care team by improving the career development system， increasing salary and welfare benefits， and expanding social recognition.

Objective:To study the early predictors of refractory septic shock (RSS) in neonates.Methods:From July 2020 to December 2021, clinical data of neonates with septic shock admitted to the Neonatal Department of our hospital were retrospectively reviewed. According to the maximum septic shock score (SSS) during clinical course, the neonates were assigned into RSS group and non-RSS group. Perinatal data, laboratory results and hemodynamic parameters at diagnosis were compared between the two groups. Multiple logistic regression analysis was used to identify independent risk factors of RSS and septic shock-related death. Receiver operating characteristic (ROC) curve was constructed to evaluate the early predictors of poor prognosis.Results:A total of 130 neonates were enrolled, including 54 in RSS group and 76 in non-RSS group. Compared with the non-RSS group, the RSS group had significantly lower pH, base excess (BE), stroke volume index (SVI), cardiac output (CO) and cardiac index (CI).Meanwhile, the RSS group had significantly higher mean arterial pressure (MAP) to CI ratio (MAP/CI) and SSS [including bedside SSS (bSSS), computed SSS (cSSS) and modified version of cSSS (mcSSS)] (all P<0.05). Multiple logistic regression analysis showed that increased MAP/CI was an independent predictor of RSS. The cut-off value of MAP/CI was 11.6 [sensitivity 62%, specificity 87%, positive predictive value (PPV) 79% and negative predictive value (NPV) 77%], with an area under the curve (AUC) of 0.734. Increased mcSSS was an independent predictor of septic shock-related death. The cut-off value of mcSSS was 5.8 (sensitivity 83%, specificity 72%, PPV 21% and NPV 97%), with an AUC of 0.845. Conclusions:Increased MAP/CI (≥11.6) and mcSSS (≥5.8) may be early predictors of RSS and septic shock-related death in neonates.

Objective:To establish an in vivo infection model of West Nile virus (WNV) pseudovirus and evaluate the neutralizing activity of antibody WNV-XH1.Methods:A stable cell line that can package the WNV pseudovirus was established in the early stage to prepare the pseudovirus supernatant. The supernatant was concentrated and infected BHK21 cells to detect the titer of the pseudovirus. After intraperitoneal injection of the pseudovirus into C57BL/J mice, bioluminescence imaging was performed to observe the infection status of the pseudovirus in the mice. After simultaneous infection, blood was collected and ELISA was used to detect NS1 levels in mouse serum. The in vivo functional activity of antibody WNV-XH1 was evaluated using the established mouse infection model.Results:Fluorescence was detected in C57BL/J mice infected with WNV pseudovirus, and the NS1 levels in the peripheral blood serum of mice infected with pseudovirus were significantly higher than those of non infected mice (1.453±0.09vs0.305±0.018). After intravenous administration of WNV-XH1 antibody before the attack, the fluorescence signal in the mice decreased and the serum NS1 level decreased (0.384±0.015).Conclusions:A successful in vivo infection model of WNV pseudovirus was established, and it was confirmed that the antibody WNV-XH1 had a protective effect against WNV pseudovirus infection in vivo.

Objective:To construct a core muscle strength training plan for patients with lumbar degenerative diseases based on the concept of pre-rehabilitation, and provide a theoretical basis for core muscle strength training for patients with lumbar degenerative diseases.Methods:From January 2022 to June 2023 based on literature search and group discussion, develop a primary item pool for core muscle strength training plan for patients with lumbar degenerative diseases under the concept of pre-rehabilitation. Through two rounds of Delphi expert consultation, revise and establish the core muscle strength training plan for patients with lumbar degenerative diseases under the concept of pre-rehabilitation.Results:A total of 15 experts were consulted by letter, including 3 males and 12 females, aged 35-58 (41.38 ± 5.44) years old. The positive coefficients of two rounds of correspondence with experts were 1.00 and 0.93, the expert judgment coefficients were 0.78 and 0.90, the familiarity coefficients were 0.84 and 0.92, and the authority coefficients were 0.81 and 0.91. The Kendall coordination coefficients of two rounds of inquiry had statistical significance in terms of indicator rationality (0.378, 0.384), indicator importance (0.283, 0.291), and indicator operability (0.263, 0.375) (all P<0.05). The constructed perioperative nursing quality sensitive indicator system for minimally invasive spinal surgery patients included 3 primary indicators, 9 secondary indicators, and 17 tertiary indicators. Conclusions:The core muscle strength training plan for patients with lumbar degenerative diseases based on the concept of pre- rehabilitation is scientific, reliable, practical, and feasible, and can provide a theoretical basis for core muscle strength training for patients with lumbar degenerative diseases.

Objective:To understand the dilemma of active management in young and middle-aged postoperative patients with lumbar disc herniation, in order to provide reference for the formulation of active intervention program of self-health management meeting the needs of patients.Methods:Using the phenomenological research method, a total of 16 middle-aged and young patients with lumbar disc herniation were selected for semi-structured in-depth interviews, and the themes were analyzed and extracted by Colaizzi 7-step analysis method.Results:Three themes and nine sub-themes were extracted namely, inadequate disease response capacity and response resources (lack of disease symptom management capacity, limited access to disease management information, difficult use of disease management information, difficulty in maintaining positive self-management for a long time (forced to stop behavior change due to stress, lack of motivation to achieve good behavior change, doubts about the effectiveness of self-management) and multi-dimensional negative emotions (contrast between maintaining independence and dependence on others, fear of being misunderstood, fear of relapse) .Conclusions:Medical staff should provide comprehensive health information services for young and middle-aged postoperative patients with lumbar disc herniation, improve the out-of-hospital follow-up mechanism with the help of information technology, further improve family and social support strategies, reduce the difficulties faced in the process of active management and achieve long-term active disease management.

Objective:To summarize the best evidence for the use of ankle pump exercises in preventing perioperative lower limb deep vein thrombosis (DVT) in patients undergoing joint replacement surgery and to evaluate its clinical application.Methods:This study utilized an evidence-based continuous quality improvement model. A systematic search was conducted for relevant clinical practice guidelines, expert consensus, systematic reviews, and randomized controlled trials (RCTs) from both domestic and international sources. The best evidence was evaluated and summarized, and audit indicators were developed for baseline assessments. Facilitating and hindering factors were analyzed based on the baseline results. From December 2022 to April 2023, the evidence was applied in the Department of Orthopedics at Henan Provincial People's Hospital. The pre-evidence group for baseline assessments included 36 joint replacement patients and 18 nurses from the orthopedic unit between December 2022 and January 2023, while the post-evidence group included 36 joint replacement patients and the same 18 nurses between March and April 2023. The knowledge level of nurses, the effectiveness of ankle pump exercises, the execution rate, and patient compliance were compared before and after evidence-based practice.Results:A total of 12 articles were included in the study, comprising one clinical practice guideline, five expert consensus papers, one systematic review, and five RCTs. Ten best practices were summarized in terms of applicable populations, exercise assessment, exercise positions, timing, methods, frequency, and patient education. After implementing evidence-based practice, the knowledge scores of nurses on ankle pump exercises significantly improved from (70.56±9.98) to (82.78±8.26) ( P<0.01). The compliance rates of audit items 2, 3, 4, 5, and 6 among nurses increased from 0, 22.2%, 0, 27.8%, and 11.1% respectively, to 94.4%, 94.4%, 83.3%, 100.0%, and 100.0% respectively ( P<0.01). On the patient side, the compliance rates for audit items 7 and 8 increased from 5.6% and 0 to 86.1% and 94.4%, respectively ( P<0.01) . Conclusions:Implementing evidence-based ankle pump exercises to prevent DVT in joint replacement patients can significantly improve nurses' knowledge of evidence-based practice, standardize the practice of ankle pump exercises, and explore balanced educational strategies that enhance patient compliance, ensuring clinical practices are evidence-based.

Objective:To study the predictive value of vasoactive-inotropic score (VIS), fluid overload (FO) and lactate level for the outcome of preterm infants with refractory septic shock.Methods:Preterm infants diagnosed with refractory septic shock and required hydrocortisone treatment in our Department from January 2016 to December 2021 were analyzed retrospectively. Preterm infants were assigned into three gestational age groups (<28 weeks, 28-31 weeks, 32-36 weeks). According to the outcome of the disease, the children were further divided into good prognosis group and poor prognosis group. The relationship between the maximum VIS, FO and the mean lactic acid before hydrocortisone and the outcome of refractory septic shock was analyzed by receiver operating characteristic (ROC) curve, the cut-off point of ROC curve was calculated to obtain the predictive efficacy of the three indicators for the outcome of refractory septic shock in preterm infants.Results:A total of 50 preterm infants with refractory septic shock and received hydrocortisone treatment were enrolled, including 20 in the good prognosis group and 30 in the poor prognosis group. There were no significant differences in the maximum VIS, FO and mean lactic acid before hydrocortisone treatment between the two groups of gestational age of <32 weeks ( P> 0.05). The maximum VIS, FO and mean lactic acid of gestational age of 32-36 weeks in the poor prognosis group were higher than those in the good prognosis group, VIS: 56.1±15.7 vs. 37.1±12.9, FO (%): 108.2 (78.6,137.7) vs. 55.5 (10.3, 100.7), and mean lactic acid (mmol/L): 8.3 (4.6, 12.0) vs. 4.8 (-0.8, 10.5), all P<0.05. The area under the ROC curve of the mean lactic acid was the largest, the cut-off value was 4.1 mmol/L, and the Youden index was 1.732. Conclusions:VIS, FO and lactate level are difficult to be used for determining the outcome of refractory septic shock in preterm infants of <32 weeks. While the mean lactic acid has the best predictive performance in preterm infants of 32-36 weeks.

Objective:To explore the effect of quality improvement of hemodynamic monitoring on fluid overload (FO) and outcome in newborns with septic shock.Methods:Non-invasive cardiac output monitoring and functional cardiac ultrasound quality improvement program was started during January 2020 in our hospital. Neonates with septic shock admitted before and after the program were retrospectively analyzed. From January 2018 to December 2019 was pre-improvement period when fluid resuscitation was routinely performed and vasoactive drugs was selected empirically. From January 2020 to December 2021 was post-improvement period when fluid resuscitation and/or use and adjustment of vasoactive drugs were guided by hemodynamic parameters. The 24 h, 48 h, 72 h FO, duration of invasive respiratory support, vasoactive-inotropic score, septic shock score, incidences of complications and all-cause mortality were compared between the two groups.Results:A total of 284 eligible cases were enrolled, including 136 cases in pre-improvement group and 148 cases in post-improvement group. Post-improvement group had significantly lower gestational age (GA), birth weight (BW) and body weight at disease onset than pre-improvement group ( P<0.05). Incidences of 48 h and 72 h FO, fluid resuscitation volume within 72 h, pulmonary hemorrhage and periventricular leukomalacia (PVL) were significantly lower in the post-improvement group ( P<0.05). No significant differences existed in 24 h FO, other complications and all-cause mortality between the two groups ( P>0.05). No significant differences existed in GA and BW for neonates with pulmonary hemorrhage and PVL between the two groups ( P>0.05). Conclusions:Quality improvement of hemodynamic monitoring can effectively improve FO and reduce the incidences of pulmonary hemorrhage and PVL.

Objective:To observe the application effect of health education based on health action process approach (HAPA) theory in perioperative patients undergoing knee arthroplasty.Methods:Using the convenient sampling method, a total of 168 patients who underwent knee arthroplasty in Henan Provincial People's Hospital from March 2020 to May 2021 were selected, and they were randomly divided into the observation group (85 cases) and the control group (83 cases). The control group received routine care, while the observation group received health education based on HAPA theory on the basis of the control group. The scores of Self-efficacy for Rehabilitation Outcome Scale (SER) and Quality of Life Questionnaire Core 30 (QLQ-C30), postoperative recovery indicators and complications, patient compliance and patient satisfaction before and after intervention were compared between the two groups.Results:After intervention, scores of SER, QLQ-C30, compliance and satisfaction in the observation group were higher than those in the control group, and the differences were statistically significant ( P<0.05). The first time of getting out of bed, the time of knee flexion greater than or equal to 90°and the length of hospital stay in the observation group was shorter than those in the control group, and the total incidence of complications was lower than that in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Health education based on HAPA theory can effectively improve the self-efficacy, compliance and quality of life of patients undergoing knee arthroplasty, reduce the risk of complications, promote postoperative recovery and obtain satisfaction of patients.

Objective:To explore the effect of feedback health education combined with positive psychological suggestion on the rehabilitation of patients undergoing artificial total knee arthroplasty.Methods:From August 2020 to July 2021, the convenient sampling method was used to select 126 patients with artificial total knee arthroplasty admitted to the Orthopedic Department of Henan Provincial People's Hospital. They were randomly divided into the control group and the observation group in a 1∶1 ratio using a random number table method. The control group received routine health education combined with positive psychological suggestion, while the observation group received feedback based health education combined with positive psychological suggestion intervention. The level of knowledge, attitude and practice, scores on the Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), Visual Analogue Scale (VAS), American Knee Society (AKS) score, knee swelling rate and nursing satisfaction were compared between two groups of patients.Results:The knowledge, attitude and practice scores of the two groups at discharge were higher than those at admission ( P<0.05), and the knowledge, attitude and practice scores of the observation group were higher than those of the control group at discharge ( P<0.05). The SAS and SDS scores of the observation group were lower than those of the control group before and on the third day after surgery ( P<0.05). The VAS of the observation group on the first day and 2 weeks after surgery were lower than those of the control group ( P<0.05), while AKS was higher than that of the control group ( P<0.05). The postoperative swelling rates in the observation group were lower than those in the control group at 1 week and 3 months after surgery ( P<0.05). The nursing satisfaction scores of the observation group in terms of health education, service attitude, department environment, psychological intervention, and nursing outcomes were higher than those of the control group ( P<0.05) . Conclusions:Feedback health education combined with positive psychological cues can improve the knowledge, attitude and practice levels of patients undergoing artificial total knee arthroplasty, reduce anxiety and depression, and improve rehabilitation effectiveness and nursing satisfaction.
