Objective To retrieve, evaluate, and summarize evidence on preventive management of high output and dehydration in ileostomy patients from both domestic and international sources. Methods Based on the "6S" evidence model, a top-down approach was employed to retrieve evidence on prevention and management of high output and dehydration in ileostomy patients. Databases searched included BMJ best practice, UpToDate, National Guideline Clearinghouse (NGC), National Institute for Health and Care Excellence (NICE), Scottish Intercollegiate Guidelines Network (SIGN), Registered Nurses' Association of Ontario (RNAO), Wound Ostomy and Continence Nurses Society (WOCNS), World Council of Enterostomal Therapists (WCET), Medlive Clinical Guidelines website, Joanna Briggs Institute (JBI), Cochrane Library, Embase, PubMed, Web of Science, CNKI, Wanfang Data, China Biology Medicine (CBM), and VIP Database. The search period was from January 2019 to April 2024. Results A total of 13 articles were included after retrieval and screening, comprising 2 guidelines, 2 expert consensuses, 4 systematic reviews, 4 evidence summaries, and 1 clinical decision aid. After translation, summarization, and organization of the included articles, 19 pieces of evidence across 11 categories were formulated, focusing on four items: definition and risk factors of high output in ileostomy, prevention and management strategies related to high output in ileostomy, prevention and management strategies related to dehydration in high-output ileostomy, and follow-up strategies for prevention of high output and dehydration after ileostomy surgery. Conclusion The evidence summarized based on the "6S" evidence model for prevention and management of high output and dehydration in ileostomy patients can provide a reference for clinical practice among healthcare professionals and medical decision-makers, thereby enhancing nursing quality and reducing patient rehospitalization rates.

Objective: Cardiac magnetic resonance (CMR) is a diagnostic tool that provides precise and reproducible information about cardiac structure, function, and tissue characterization, aiding in the monitoring of chemotherapy response in patients with lightchain cardiac amyloidosis (AL-CA). This study aimed to evaluate the feasibility of CMR in monitoring responses to chemotherapy in patients with AL-CA. Materials and Methods: In this prospective study, we enrolled 111 patients with AL-CA (50.5% male; median age, 54 [interquartile range, 49–63] years). Patients underwent longitudinal monitoring using biomarkers and CMR imaging. At followup after chemotherapy, patients were categorized into superior and inferior response groups based on their hematological and cardiac laboratory responses to chemotherapy. Changes in CMR findings across therapies and differences between response groups were analyzed. Results: Following chemotherapy (before vs. after), there were significant increases in myocardial T2 (43.6 ± 3.5 ms vs. 44.6 ± 4.1 ms; P = 0.008), recovery in right ventricular (RV) longitudinal strain (median of -9.6% vs. -11.7%; P = 0.031), and decrease in RV extracellular volume fraction (ECV) (median of 53.9% vs. 51.6%; P = 0.048). These changes were more pronounced in the superior-response group. Patients with superior cardiac laboratory response showed significantly greater reductions in RV ECV (-2.9% [interquartile range, -8.7%–1.1%] vs. 1.7% [-5.5%–7.1%]; P = 0.017) and left ventricular ECV (-2.0% [-6.0%–1.3%] vs. 2.0% [-3.0%–5.0%]; P = 0.01) compared with those with inferior response. Conclusion Cardiac amyloid deposition can regress following chemotherapy in patients with AL-CA, particularly showing more prominent regression, possibly earlier, in the RV. CMR emerges as an effective tool for monitoring associated tissue characteristics and ventricular functional recovery in patients with AL-CA undergoing chemotherapy, thereby supporting its utility in treatment response assessment.

Primary light-chain (AL) amyloidosis is a rare and fatal plasma cell disease. In recent years, the treatment of AL amyloidosis has changed from the era of bortezomib to the era of daratumumab immunotherapy. However, for the treatment choice of advanced-staged patients, how to achieve organ responses at the early stage and how to monitor the disease are questions that need to be further explored. The 64th American Society of Hematology Annual Meeting in 2022 has reported advances in the diagnosis and treatment of AL amyloidosis, which are briefly reviewed in this article.

OX40 is a costimulatory receptor that is expressed primarily on activated CD4⁺, CD8⁺, and regulatory T cells. The ligation of OX40 to its sole ligand OX40L potentiates T cell expansion, differentiation, and activation and also promotes dendritic cells to mature to enhance their cytokine production. Therefore, the use of agonistic anti-OX40 antibodies for cancer immunotherapy has gained great interest. However, most of the agonistic anti-OX40 antibodies in the clinic are OX40L-competitive and show limited efficacy. Here, we discovered that BGB-A445, a non-ligand-competitive agonistic anti-OX40 antibody currently under clinical investigation, induced optimal T cell activation without impairing dendritic cell function. In addition, BGB-A445 dose-dependently and significantly depleted regulatory T cells in vitro and in vivo via antibody-dependent cellular cytotoxicity. In the MC38 syngeneic model established in humanized OX40 knock-in mice, BGB-A445 demonstrated robust and dose-dependent antitumor efficacy, whereas the ligand-competitive anti-OX40 antibody showed antitumor efficacy characterized by a hook effect. Furthermore, BGB-A445 demonstrated a strong combination antitumor effect with an anti-PD-1 antibody. Taken together, our findings show that BGB-A445, which does not block OX40-OX40L interaction in contrast to clinical-stage anti-OX40 antibodies, shows superior immune-stimulating effects and antitumor efficacy and thus warrants further clinical investigation.

Objective:To investigate the pathogens and drug resistance of bacterial enteritis in children, analyze the clinical characteristics of bacterial enteritis in children, and provide basis for clinical diagnosis and treatment.Methods:The fecal culture strain and drug sensitivity of patients with bacterial enteritis admitted to our hospital from January 2016 to December 2020 were analyzed and summarized, and the clinical characteristics of patients who were infected by Salmonella and Escherichia coli were compared.Results:There were a total of 173 patients, aged from 21 days to 15 years, with a median age of 2.00(1.10, 3.54)years.Bacterial enteritis was most likely to occur in summer and autumn, and the incidence rate was 40.5% and 29.5%, respectively.One hundreds and seventy-three strains of bacteria were cultured in feces, including 148 strains of Salmonella(85.5%), 18 strains of Escherichia coli(10.4%), five strains of Staphylococcus aureus and two strains of Shigella.One hundreds and one of 141 patients who were infected with Salmonella were detected for leukocytes of in feces(71.6%), and four of 16 patients with Escherichia coli were detected for leukocytes(25.0%). The difference was significant( χ2=14.1, P<0.001). Eighty-eight of 113 patients(77.9%) who were infected by Salmonella with increased CRP(CRP>8 mg/L)and the proportion in Escherichia coli infection cases was 6/13(46.2%). There was significant difference( χ2=4.63, P=0.03). The drug sensitivity of Salmonella and Escherichia coli was summarized.There was no carbapenem resistant strain cultured; The sensitivity to piperacillin/tazobactam and cefoperazone/sulbactam was higher than 85%; The sensitivity to cefepime, ceftazidimeand ceftriaxone was higher than 75%; The sensitivity to ampicillin was lower than 30%, and the sensitivity to quinolones was between 20%-40%. Conclusion:Children aged 1-3 years are prone to bacterial enteritis in summer and autumn.The most common pathogens causing bacterial enteritis are Salmonella and Escherichia coli.White blood cells are more easily detected in feces of patients with Salmonella infection, and the increase rate of C-reactive protein in peripheral blood is higher.Patients with bacterial enteritis are recommended to use the third-generation cephalosporins and aforementioned antibiotics and piperacillin/tazobactam for empirical treatment.The sensitivity to quinolones is reduced, and may not be suitable for clinical application.

Background::The potential impact of β cell function and insulin sensitivity on adverse pregnancy outcomes in women with gestational diabetes mellitus (GDM) remains uncertain. We aimed to investigate the association between β cell dysfunction, insulin resistance, and the composite adverse pregnancy outcomes.Methods::This observational study included 482 women diagnosed with GDM during pregnancy. Quantitative metrics on β cell function and insulin sensitivity during pregnancy were calculated using traditional equations. The association of β cell dysfunction and insulin resistance with the risk of the composite adverse pregnancy outcomes was investigated using multivariable-adjusted logistic regression models.Results::Multivariable-adjusted odds ratios (ORs) of adverse pregnancy outcomes across quartiles of homeostatic model assessment for insulin resistance (HOMA-IR) were 1.00, 0.95, 1.34, and 2.25, respectively ( P for trend = 0.011). When HOMA-IR was considered as a continuous variable, the multivariable-adjusted OR of adverse pregnancy outcomes was 1.34 (95% confidence interval 1.16-1.56) for each 1-unit increase in HOMA-IR. Multivariable-adjusted ORs of adverse pregnancy outcomes across quartiles of homeostatic model assessment for β cell function (HOMA-β) were 1.00, 0.51, 0.60, and 0.53, respectively ( P for trend = 0.068). When HOMA-β was considered as a continuous variable, the multivariable-adjusted OR of adverse pregnancy outcomes was 0.57 (95% CI 0.24-0.90) for each 1-unit increase in HOMA-β. However, other quantitative metrics were not associated with the composite adverse pregnancy outcomes. Conclusions::We demonstrated a significant association of β cell function and insulin sensitivity with the risk of adverse pregnancy outcomes. We have provided additional evidence on the early identification of adverse pregnancy outcomes besides the glycemic values.

Objective:To explore a new method of ultrasound-guided positioning of the tip of neonatal peri-pherally inserted central catheter (PICC).Methods:Clinical data of 174 newborn infants hospitalized in the Neonatal Intensive Care Unit (NICU) of Beijing Chaoyang District Maternal and Child Healthcare Hospital from January 2019 to April 2021 receiving PICC catheter intubated under the guidance of ultrasound for positioning the tip were retrospectively analyzed to explore the accuracy, reliability and feasibility of the improved ultrasound-guided positioning technique.Before lower extremity catheterization, ultrasound was performed to monitor the vascular pattern and catheterization of PICC was conducted under the guidance of ultrasound.Results:(1) Among 174 infants intubated with ultrasound-guided positioning of the PICC tip, 172(98.9%) of them had the ideal position, and 2(1.1%) did not achieve the ideal position, but achieved the ideal position after ultrasound-guided correction.(2) Lower extremity venous catheterization was successfully performed at 100.0% after ultrasound-guided monitoring of blood vessels.The time-consuming of lower extremity venous catheterization was significantly shorter than that of the previous method [(31.50±2.58) min vs.(56.10 ±5.30 min)]( t=46.84, P<0.001). The total success rate of catheterization and catheterization of lower limb vein increased by 7.0% and 17.5%, respectively.(3) Only 1 (0.57%) case reported the complication of catheter tip thrombosis, the complication rate of which decreased from the previous 79.00% to 2.70%(2/112 cases). Conclusions:The improved ultrasound-guided positioning of the PICC tip is convenient, simple, faster and accurate, which enhances the success rate and is worthy to be applied in clinical practice.

Objective:The aim of the study was to develop a transcultural adaptation of Scrub Practitioners ′ List of Intraoperative Non-technical Skills to Chinese. Methods:The translation of SPLINTS was based on the Brislin ′s translation model and expert consultation were conducted for cultural adaptation before the Chinese version was accomplished. The content validity of Chinese version scale was evaluated by Delphi method. The applicability and observer reliability of the tool was tested by behavioral observation of simulate videos. Results:The positive coefficients of experts in the first and second rounds were both 100% and the authority coefficients were 0.802 and 0.906 respectively. The concordancy coefficients of expert Kendall were 0.282-0.433( P<0.05). The results of Delphi expert consultation showed that the average content validity index (S-CVI/Ave) of the scale level was 0.93, and the item level (I-CVI) content validity index was 0.87-1.00. The rater training showed that the intra-observer reliability was 0.75-0.96 and inter-observer reliability (Kendall W) was 0.502-0.557( P<0.01). Conclusion:The cross-cultural adaptation of SPLINTS-Chinese version is scientific and reliable. The content validation and observer reliability are in-line with scale evaluation criteria. Further psychometric measurement can be conducted in the group of scrub nurses in the operating room.

Objective: To investigate the value of ultrasound in the localization of peripherally inserted central catheter (PICC) in neonates. Methods: A retrospective analysis of the PICC catheterization was conducted at Department of Neonatology, Beijing Chaoyang District Maternal and Child Healthcare Hospital from June 2017 to December 2018.The ultrasound monitoring was performed immediately after PICC catheterization.The probe was placed into the midline position of the lower xiphoid or the subclavian parasternal line for scanning, and it would be the PICC if a high-echo " equal sign" was observed by ultrasound.It was believed that the PICC was successfully placed when ultrasound detected that the PICC tip was located in the junction of inferior vena cava or superior vena cava in the right atrium. Results: (1)Among 112 infants with PICC catheterization, 103 cases (92.0%) were accurately placed, 9 cases (8.0%) were not placed in the ideal site, among them, 2 cases were too deep, 4 cases were too shallow and 3 cases were catheter heterotopia.The tip position was accurate after the readjustment under ultrasound monitoring in those patients whose the first ultrasound showed the tip position was not ideal.(2)The PICC indwelling time was as short as 2 days (removed due to severe arrhythmia) and as long as 56 days with an average of (15.1±10.7) days.(3)The catheter-related complications occurred in 3 cases with an incidence of 2.7%. Conclusions Using ultrasound to determine the PICC tips position is accurate and reliable, which is worthy of extensive application in the neonatal wards.
