Objective To explore the application effect of a standardized management method based on failure mode and effect analysis （FMEA） in optimizing the whole-process quality control system of the intravenous admixture service （PIVAS）. Methods The quality control management system of the PIVAS was optimized by establishing six quality control groups led by the head nurse, with full participation of pharmacy, nursing, and logistical staff, ensuring comprehensive coverage and traceability of all quality control links. Each group conducted risk priority number （RPN） scoring for potential failure modes in their respective quality control processes, and targeted improvement measures were formulated based on the scoring results. The RPN values of failure modes and quality control-related evaluation indicators before and after implementation were compared to achieve closed-loop management. Results After one year of management, the RPN values of the six major failure modes significantly decreased compared to those before implementation （P<0.05）. The compounding error rate dropped to 0.13%, the dispensing error rate decreased to 0.95%, the compounding efficiency increased to 98%, the delivery time was shortened by 0.45 h per batch, the intervention rate for irrational prescriptions rose to 94.87%, satisfaction improved to 96.78%, and the participation rate of quality control personnel reached 95.36% （P<0.05）. Conclusion FMEA-based identification of potential failure modes in the whole-process quality control system of the IVAS, combined with risk quantification and targeted interventions, significantly reduced high-risk failure modes, improved compounding accuracy and efficiency, and ensured the safety of clinical intravenous medication and the effectiveness of healthcare quality management.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

OBJECTIVE To analyze the clinical characteristics of the 12 patients tested with Candida auris in a three-A hospital so as to provide guidance for prevention and control of nosocomial C.auris infection.METHODS The specimens sources and departments where the C.auris strains were isolated as well as the drug resistance were retrospectively collected from Zhongda Hospital Affiliated to Southeast University between Sep.2023 and Jun.2024.The clinical characteristics of the patients with C.auris infection were summarized.The epidemiological survey was conducted for the possibility of its transmission in hospitals,and the corresponding modified preven-tion measures were put forward.RESULTS Among the 12 patients who were tested with C.auris,10 were male,and 2 were female;the age ranged between 21 and 92 years old.Most of the patients were complicated with multi-ple underlying diseases and had the history of repeated hospitalization as well as the history of invasive operation procedures such as tracheotomy,urinary catheterization,gastric tube indwelling and venoarterial catheterization;in the meantime,other multidrug-resistant organisms(MDROs)and fungi were tested in those patients,and the patients used multiple types of antibiotics.Totally 16 strains of C.auris were isolated from the 12 patients with C.auris tested,62.50％(10/16)of which were isolated from urine specimens,18.75％(3/16)were isolated from sputum specimens,and 6.25％(1/16)were isolated from deep venous catheter,tissue biopsy and wound swab specimens.All of the 16 strains of C.auris were resistant to fluconazole and sensitive to caspofungin;4 strains were resistant to amphotericin B.Totally 2 patients had Candida auris infection,one was pulmonary infection,and the other was urinary tract infection,and the infection rate was 16.67％;both patients were cured.There were 10 cases of colonization,and the colonization rate was 83.33％.The result of epidemiological survey indicated that the C.auris that was tested in the No.8 patient may originate from the No.4 patient who carelessly brought from outside the hospital due to poor implementation of standardized prevention measures.CONCLUSIONS The patients tested with C.auris usually have complicated medical backgrounds.Although the colonized C.auris strains are dominant among the strains in the hospital,the related departments need to intensify the implementation of pre-vention measures so as to prevent the transmission of C.auris and pay special attention to the early identification and management of imported pathogens.

Objective This study was performed to explore the use of intramuscular low-dose Zoletil(1.5 mg/kg)combined with isoflurane inhalation for tracheal intubation in miniature pigs while preserving spontaneous respiration by determining the 50％and 95％minimum alveolar concentrations effective inhaled(MAC EI50 and MAC EI95).The goal was to establish a safe anesthetic method for tracheal intubation in miniature pigs in which intubation is difficult.Methods Forty-four Bama miniature pigs underwent general anesthesia.Following sedation with an intramuscular injection of sufentanil,anesthetic induction was performed using mask inhalation of isoflurane with monitoring of the heart rate,blood pressure,respiration,body temperature,oxygen saturation,end-tidal carbon dioxide concentration,and end-tidal isoflurane concentration.The initial end-tidal isoflurane concentration was set at 2.0％.The tracheal intubation conditions and outcomes were evaluated using Cooper's scoring system,and the dose-response relationship was calculated using Dixon's up-and-down method.Probit regression was employed to calculate the MAC EI50 and MAC EI95 along with their 95％confidence intervals(CI).Results In tracheal intubation using direct laryngoscopy with induction by low-dose sufentanil combined with isoflurane inhalation in miniature pigs,the MAC EI50 was 3.10％(95％CI,2.79％～3.56％)and the MAC EI95 was 3.77％(95％CI,3.41％～6.42％).With proper monitoring and airway management planning in place,alveolar isoflurane concentrations ranging from 3.10％to 3.75％were able to maintain stable vital signs in the miniature pigs.Conclusions The use of Zoletil combined with isoflurane inhalation for tracheal intubation in miniature pigs,aimed at preserving spontaneous breathing,is a preferable and safe anesthetic method for oral airway management in miniature pigs with significant potential for widespread application.

Objective:To explore the association between postoperative radiotherapy for bladder cancer and the risk of second primary rectal cancer.Methods:Eligible 75 120 patients with bladder cancer from the Surveillance, Epidemiology, and End Result database (SEER) of the National Cancer Institute (NCI) (1975-2017) were enrolled in this study. The second primary cancers referred to rectal cancers patients suffered after more than five years post-treatment for bladder cancer, and the cumulative incidence was estimated using Fine-Gray competing risk regression. The relative risk (RR) of rectal cancer in patients treated with or without radiotherapy (the RT group or the NRT group) was evaluated using Poisson regression.Results:Among the 75 120 patients, 70 045 (92.4%) were Caucasian, with a median age of 65.8 years (54-74 years). A total of 2 236 (3%) received postoperative radiotherapy, while 72 884 (97%) received surgery alone. The 30-year follow-up revealed a cumulative incidence of rectal cancer of 0.93% in the RT group and 0.43% in the NRT group ( P = 0.004). The competing risk regression analysis identified a significant association between radiotherapy and rectal cancer ( HR: 1.86; 95% CI 1.26-2.74, P < 0.009). Furthermore, the RR of radiotherapy-associated rectal cancer significantly increased as the diagnosis occurred earlier (1975-1985 vs. 1985-1994: RR 2.59; 95% CI 1.20-4.86, P < 0.001), and a lower age at the time of radiotherapy was associated with a higher probability of second primary tumors (≤50-year old vs. > 50 year old : RR 7.89, 95% CI 2.97-21.30, P < 0.001). As calculated using the Poisson distribution, the RR of second rectal tumors was higher in the RT group ( RR: 2.20, 95% CI 1.45-3.18, P < 0.001), even after adjusting the date of diagnosis ( RR: 1.77, 95% CI 1.17-2.57, P = 0.009). Conclusions:An increased risk of rectal cancer following bladder cancer radiotherapy necessitates aggressive follow-ups for the purpose of early detecting second primary rectal cancer associated with bladder cancer radiotherapy.

Objective:To explore the relationship between periprosthetic infection and preoperative serum levels of human β-defensin 3 (HBd-3) and interleukin-12 (IL-12) in patients with femoral neck fracture after hip replacement surgery.Methods:A prospective study was conducted to 268 patients with femoral neck fracture who underwent hip replacement surgery at Chengde Central Hospital from April 2020 to April 2022. They were divided into an infected group and an uninfected group based on whether they had periprosthetic infection within 2 weeks after surgery. The baseline data and preoperative laboratory indicators of the two groups were compared, and the relationship between preoperative serum HBd-3 and IL-12 levels and postoperative periprosthetic infection in patients was mainly analyzed.Results:Seventeen out of 268 patients with femoral neck fractures experienced periprosthetic infections after hip replacement surgery, with an infection rate of 6.34%(17/268). The body mass index, operation time, postoperative drainage time and IL-12 in the infected group were higher than those in the uninfected group: (23.75 ± 2.18) kg/m 2 vs. (21.86 ± 1.95) kg/m 2, (124.82 ± 15.93) min vs. (116.92 ± 14.75) min, (57.41±7.81) min vs. (49.65 ± 5.73) min, (64.82 ± 11.59) ng/L vs. (54.23 ± 9.55) ng/L, the preoperative albumin and HBd-3 were lower than those in the uninfected group: (32.56±4.63) g/L vs. (37.25 ± 5.81) g/L, (38.03 ± 6.74) μg/L vs. (46.84 ± 8.93) μg/L, and the differences were statistically significant ( P<0.05). The results of Logistic regression analysis showed that high body mass index, long surgical and postoperative drainage time, and high preoperative IL-12 levels were risk factors for periprosthetic infection after hip replacement surgery in patients with femoral neck fractures ( OR>1, P<0.05), while preoperative serum albumin and HBd-3 levels were protective factors ( OR<1, P<0.05). Receiver operating characteristic curve results showed that preoperative serum HBd-3 and IL-12 alone and in combination predict AUC>0.70 for periprosthetic infection in patients with femoral neck fracture after hip replacement surgery, which had certain predictive value. The restricted cubic spline method combining spline function and Logistic regression was used for analysis, and the results showed a linear dose-response relationship between the levels of HBd-3 and IL-12 and the strength of the association with periprosthetic infection after hip replacement surgery in patients with femoral neck fracture ( P<0.05). Conclusions:Preoperative serum HBd-3 and IL-12 levels are associated with periprosthetic infection in patients with femoral neck fracture after hip replacement surgery, and can serve as predictive indicators for infection occurrence.

Objective:To explore the risk factors for recurrence of intussusception in children after successful ultrasound-guided saline enema reduction.Methods:The clinical and follow up data of 355 hospitalized children with intussusception at the First Affiliated Hospital of Zhengzhou University from Feb 2018 to Feb 2023 were reviewed.Patients were divided into two groups by recurrence develped and the differences were compared, Data with significant differences were incorporated into multi-factor logistic analysis.Results:The overall recurrence rate was 15.8% (56/355). By univariate variable analysis model, there were statistically significant differences between the two groups in age, previous intussusception history, vomiting, maximum diameter of concentric circles shown by ultrasound, and concurrent bowel organic diseases (lead points) (all P<0.05). In multivariate Logistic regression model, age, previous intussusception history, maximum diameter of concentric circles, and lead points were independent risk factors for recurrent intussusception after saline enema.The optimal cut-off values for age and maximum diameter of concentric circles were 2 years and 33.5 mm, respectively, according to ROC curve analysis. Conclusion:Age older than 2 years, previous intussusception history, maximum diameter of concentric circles longer than 33.5 mm, and lead points are independent risk factors for recurrence after saline enema.
