Objectives This analysis aims to better reflect the value of new antibiotic treatment strategies, thereby informing clinical antibiotic use, antimicrobial reimbursement and/or hospital formulary decision-making in China.Design We adapted a published and validated dynamic disease transmission and cost-effectiveness model to evaluate the clinical and economic outcomes of introducing a new antibiotic, ceftazidime/avibactam (CAZ-AVI) for treating resistant infections in Zhejiang province, China. Outcomes were assessed over a 10-year infectious period and an annual discount rate of 5%. Costs were extracted from the hospital’s Health Information System (HIS) and obtained after data cleaning, aggregation and discounting.Setting The Chinese healthcare system perspective.Participants 10 905 patients in a Chinese tier-3 hospital from 2018 to 2021 with any of the three common infections (complicated intra-abdominal infection (cIAI), hospital-acquired/ventilator-associated pneumonia (HAP/VAP) and infections with limited treatment options (LTO)) caused by three common resistant pathogens (Escherichia coli, Klebsiella spp. and Pseudomonas aeruginosa).Interventions (1) Current treatment strategy (piperacillin-tazobactam (pip/taz) and meropenem); (2) CAZ-AVI at the third line; (3) CAZ-AVI at the second line; (4) CAZ-AVI at the first line; (5) CAZ/AVI first line, two lines diversified (i.e., equal pip/taz and CAZ-AVI at the first line; meropenem at the last line) and (6) CAZ/AVI first line, all-lines diversified.Primary outcome measures Quality-adjusted life years (QALYs) lost, hospitalisation costs and incremental net monetary benefit (INMB) were used to assess cost-effectiveness.Results Over 10 years, the introduction of CAZ-AVI to the current treatment strategy led to lower hospitalisation costs and more QALYs across all five treatment strategies, with between 68 284 and 78 571 QALYs gained whilst saving up to US$236.37 for each additional QALY gained. The INMB of introducing CAZ-AVI is estimated up to US$3 550 811 878.Conclusions Introducing CAZ-AVI had a positive impact on clinical and economic outcomes for treating antimicrobial resistance, and diversifying the antibiotics use early in the treatment might yield the best benefits.

Abstract Background The informal caregivers of adult patients with β-thalassemia major (β-TM) bear not only physical but also emotional and economic pressures of providing care. This study is the first to evaluate the caregiver burden by Zarit Burden Interview (ZBI) of adult patients with β-TM in mainland China and to identify predictors of caregiver burden. Methods In this cross-sectional study, we conducted an online survey with snowball sampling covering seven provinces between September 1, 2021, and January 31, 2022, of patients aged ≥ 18 years with β-TM and their informal caregivers. Caregiver burden was assessed using the ZBI. Data on patient demographics, disease and therapy characteristics, and informal caregivers’ demographic characteristics were collected and analysed using independent t-tests, analysis of variance, Spearman’s correlation and multiple linear regression. Results Of 75 included patients, more than half (50.7%) were male. The mean patient age was 24.69 ± 5.59 years. The mean age of the informal caregivers was 50.60 ± 9.16 years, with women (74.7%) being predominant. The ZBI score was 38.00 ± 17.02. Multiple linear regression analysis showed that patients with interrupted blood transfusion therapy and informal caregivers required to care of others were positively associated with caregiver burden (p

Purpose: An emergency rescue situation is an inevitable challenge in medical work, requiring collaborative efforts from healthcare professionals. Due to a lack of practical experience, novice nurses may encounter difficulties in successfully managing emergency resuscitation events. This study aimed to analyse the authentic psychological experiences of novice nurses participating in emergency resuscitation events by exploring applicable coping methods and management strategies. Methods: This study utilized a hermeneutic phenomenological qualitative research method. We employed purposive sampling to select 27 Novice nurses from West China Hospital of Sichuan University for face-to-face semistructured interviews. Data collection for this study was conducted from November 2023 to January 2024. The interviews were fully audio-recorded and transcribed verbatim. The data were coded, categorized and summarized with the help of Nvivo 20.0 software based on the interpretation of phenomenological research methods. Thematic analysis was performed to deeply analyse and extract corresponding themes. The COREQ criteria were used to guide the reporting of this study. Results: The authentic psychological experiences of novice nurses participating in emergency rescue events mainly include six aspects: lack of rescue knowledge reserves and related abilities, psychological and emotional changes, psychological stress after the rescue, rational arrangement of manpower, team cooperation, and postevent reflection and learning. Their authentic psychological experiences directly affect whether novice nurses can effectively respond to emergency rescue events. Conclusions: This study suggested enhancing novice nurses' knowledge, improving their resuscitation skills, and improving their psychological well-being during resuscitation events. It advocates for organized staffing, effective teamwork, and robust support systems to empower novice nurses and improve their overall capabilities in emergencies. These findings offer valuable insights for future research in this area.

Abstract Objective This systematic review and meta-analysis investigated whether the use of azithromycin during labour or caesarean section reduces the incidence of sepsis and infection among mothers and newborns. Data sources We independently searched the PubMed, Web of Science, Cochrane Library and EMBASE databases for relevant studies published before February, 2024. Methods We included RCTs that evaluated the effect of prenatal oral or intravenous azithromycin or placebo on intrapartum or postpartum infection incidence. We included studies evaluating women who had vaginal births as well as caesarean sections. Studies reporting maternal and neonatal infections were included in the current analysis. Review Manager 5.4 was used to analyse 6 randomized clinical trials involving 44,448 mothers and 44,820 newborns. The risk of bias of each included study was assessed using the criteria outlined in the Cochrane Handbook for Systematic Reviews of Interventions.Primary outcomes included the incidence of maternal sepsis and all-cause mortality and neonatal sepsis and all-cause mortality; secondary outcomes included maternal (endometritis, wound and surgical site infections, chorioamnionitis, and urinary tract infections) and neonatal outcomes (infections of the eyes, ears and skin). A random-effects model was used to test for overall effects and heterogeneity. Results The pooled odds ratios (ORs) were as follows: 0.65 for maternal sepsis (95% CI, 0.55–0.77; I 2 , 0%; P

Aiming at the problems of the large storage, complex composition, low comprehensive utilization rate, and high environmental impact of coal gangue, this paper carried out experimental research on the preparation of iron oxide red from high-iron gangue by calcination activation, acid leaching, extraction, and the hydrothermal synthesis of coal gangue. The experimental results show that when the calcination temperature of coal gangue is 500 °C, the calcination time is 1.5 h, the optimal concentration of iron removal is 6 mol/L, the acid leaching temperature is 80 °C, the acid leaching time is 1 h, and the liquid——solid mass ratio is 4:1; the iron dissolution rate can reach 87.64%. A solvent extraction method (TBP-SK–hydrochloric acid system) was used to extract the leachate, and a solution with iron content up to 99.21% was obtained. By controlling the optimum hydrothermal conditions (pH = 9, temperature 170 °C, reaction time 5 h), high-purity iron oxide red product can be prepared; the yield is 80.07%. The red iron oxide was characterized by XRD, SEM-EDS, particle-size analysis, and ICP-OES. The results show that the red iron oxide peak has a cubic microstructure, an average particle size of 167.16 μm, and a purity of 99.16%. The quality of the prepared iron oxide red product meets the requirement of 98.5% of the “YHT4 Iron oxide Standard for ferrite”. It can be used as a raw material to produce high-performance soft magnetic ferrite. In summary, this experimental study on the preparation of iron oxide red from coal gangue is of great significance for the comprehensive utilization of coal gangue to realize the sustainable development of the environment and economy.

Background: Pain management after lung resection plays a crucial role in reducing postoperative pulmonary complications (PPCs). This study aimed to examine the effect of postoperative esketamine infusion as an adjunct to opioid analgesia on ventilation and pulmonary complications in patients underwent lung resection. Methods: Patients undergoing video-assisted thoracoscopic lung resection were randomly assigned to either the esketamine group or the control group. The esketamine group received a 24-h infusion of 1.5 mcg/ml sufentanil combined with 0.75 mcg/ml esketamine after surgery, while the control group received 1.5 mcg/ml sufentanil alone. The primary outcome measure was low minute ventilation, and the secondary outcome measures were hypoxemia, PaO2/FiO2 levels, postoperative pulmonary complications, hospital stay duration, ambulation time, Visual Analogue Scale (VAS) score, depression and anxiety levels, sleep quality, and analgesia satisfaction. Results: 80 patients were randomly divided into two groups: the esketamine group (n = 40) and the control group (n = 40). The esketamine group exhibited notably reduced incidence of low minute ventilation (P = 0.014), lower occurrence of postoperative pulmonary complications (PPCs) compared to the control group (P = 0.039), and decreased incidence of hypoxemia (P = 0.003). Furthermore, the esketamine group showed improved outcomes with lower VAS scores on the second postoperative day and enhanced sleep quality (P

Introduction: Postoperative nausea and vomiting (PONV) and pain are common and distressing complications in patients undergoing surgery. However, it remains uncertain whether timing of the postoperative course or the diel rhythm influences the occurrence of PONV or severe pain. Therefore, we aimed to explore the temporal distribution of PONV and severe pain. Material and methods: In this prospective observational study, we enrolled patients aged 18–65 years with American Society of Anesthesiologists classifications I–III, who were scheduled for surgery under general anesthesia. Patients were visited postoperatively at regular intervals (every 6 h over a 24-h period). Incidence of PONV was recorded and categorized based on real-time divisions: before dawn (00:00–05:59), morning (06:00–11:59), afternoon (12:00–17:59), and evening (18:00–23:59) and as sequential periods (i.e., 0–6, 6–12, 12–18, and 18–24 h). Severe pain and use of additional remedies were also recorded. Results: A total of 724 patients were included in the final analysis. Of these, 14.92 % experienced PONV within the first 6 h, and 8.29 % received antiemetic therapy. Occurrence of PONV and administration of remedies declined over the 24-h postoperative period. The lowest rate of PONV was observed during the pre-dawn hours (5.66 %). There was no statistically significant difference in the incidence of PONV 24-h postoperatively between surgeries with different end times. Patients underwent orthopedic surgeries had the highest incidence of PONV during 18:00–23:59, gynecological surgery patients had the highest incidence at 12:00–17:59, and 6:00–11:59 for other surgery patients. All patients had the lowest incidence during 0:00–5:59. During the initial 6-h postoperative period, 24.59 % of patients experienced severe pain, which declined in the remaining episodes. Patients who underwent orthopedic and gynecological surgeries exhibited similar temporal patterns and distribution characteristics of PONV and severe pain. Discussion: Both PONV and severe pain declined within the 24-h postoperative period, particularly within the first 6 h. Additionally, the onset patterns of PONV vary among patients undergoing different types of surgeries, all patients demonstrated decreased susceptibility to PONV between 00:00–05:59. Our findings enhance prevention and treatment strategies within an optimized timeframe during the postoperative course.

BackgroundEffective self-management can enhance a patient’s quality of life and delay disease progression. However, motivating patients to adhere to self-management behavior following percutaneous coronary intervention (PCI) remains a challenge. With the robust development of positive psychology and interdisciplinary research, the role of psychology factors in patients’ health behavior has increasingly garnered attention. This study, focusing on positive psychological qualities, aims to investigate the relationship between inner strength, hope, and self-management in patients post-PCI, and to analyze the mediating role of hope between inner strength and self-management.MethodsA cross-sectional survey was conducted among 216 PCI patients from a tertiary hospital in Nanjing. Research instruments included a self-designed general information questionnaire, the Inner Strength Scale (ISS), the Herth Hope Index (HHI), and the Coronary Self-Management Scale (CSMS). T-test, analysis of variance, Pearson’s correlation analysis, and mediating effect test were utilized for statistical analysis.ResultsThe average scores of the ISS, HHI, and CSMS were 81.46 ± 12.00, 35.94 ± 5.38, and 86.79 ± 14.84, respectively. Inner strength was positively correlated with hope and self-management (r = 0.867, r = 0.630, respectively; all P < 0.05), and hope was positively correlated with self-management (r = 0.671, P < 0.05). Moreover, hope had a complete mediating effect between inner strength and self-management (β = 0.630, P < 0.01).ConclusionThe inner strength, hope, and self-management of patients with PCI are at a moderate level. Inner strength primarily influences patients’ self-management behavior through hope, suggesting that medical staff can target hope to help patients build confidence in life after illness, form and accumulate inner strength, thereby promoting their self-management and improving prognosis.
