Despite of the widespread use of hydrogen and methane breath test, the variability in testing protocols, gas measurement techniques, and interpretation criteria continues to challenge the reproducibility and comparability across centers, especially in the Asia-Pacific region. The Asian Neurogastroenterology and Motility Association hence presents the first Asian monograph guiding application and interpretation of breath test. The monograph was formulated according to the framework of indications, preparatory process, performance, and interpretation of results, as well as future direction for research.

Background/Aims: Chronic constipation is prevalent yet under-diagnosed across Asia, compromising quality of life and burdening healthcare systems. Cultural stigma, varied diets, and limited access to standardized diagnostic tools delay timely care. Methods: The Bali Chronic Constipation Roundtable in November 2024, brought together experts from 11 Asian countries. The group reviewed epidemiological data, analyzed multinational questionnaire on clinical practice pattern, and conducted structured discussions to identify key barriers and propose region-specific recommendations. Results: Chronic constipation prevalence varies across Asia, ranging from 1.8% in India to 16.6% in Japan, with women and the elderly disproportionately affected. Under-reporting persists owing to cultural taboos and widespread self treatment with laxatives and traditional medications. Although the Rome IV criteria remains the global standard, they may not fully reflect Asian symptom profiles, and diagnosis is limited by scarce motility laboratories. First line therapies such as dietary-fiber optimization and osmotic laxatives are widely available, but newer pharmacotherapies (prucalopride, linaclotide, lubiprostone, and elobixibat) remain costly and unevenly accessible. Biofeedback for dyssynergic defecation is underutilized due to limited availability. Experts recommend expanded regional research on to refine diagnostic criteria, coupled with enhanced physician education and public awareness. They advocate accessibility to second-line and novel therapies that incorporate culturally attuned regional guidelines, and improved access to gastrointestinal motility testing. Conclusions The Bali Chronic Constipation Roundtable highlighted Asia’s need for region specific diagnostics and management. Addressing diagnostic and treatment gaps will improve outcomes, while ongoing researcher clinician policy collaboration must standardize guidelines, advance research, and ensure equitable care across Asia.

Objective:To establish a quality and safety evaluation index system for the daytime chemotherapy in the Day Medical Management Quality Control Center of Fujian Province, providing references for objectively evaluating the quality of day chemotherapy.Methods:From December 2023 to August 2024, this study screened the initial indexes of the quality and safety evaluation index system for daytime chemotherapy through literature search and expert discussions.

Objective Estimating the residual risk of transfusion-transmitted diseases in voluntary blood donors is crucial for monitoring blood safety.and to analyze the evolution trend over a five-year period in Yantai,Shandong Province.Methods This study retrospectively reviewed screening data from Yantai Central Blood Station between 2018 and 2022.We compared the positivity rates between first-time and repeat donors,calculated the prevalence of each virus,and estimated the residual risk using the prevalence-window period model.Meanwhile,the age characteristics of all positive donors were analyzed.Results Over the five-year period,a total of 320 016 individuals donated blood.The overall reaction rate of transfusion-transmitted diseases was 0.165%,with HBV(0.129%)being the most common.The positivity rate among first-time donors[P(FTDs)](0.310%)was significantly higher than that among repeat donors[P(RDs)](0.054%)(χ2=312.783,P<0.05).The serological residual risks for HBV,HCV,and HIV were 1∶188 090,1∶1 042 805,and 1∶392 995,respectively.During the five-year period,they decreased from 1∶129 495 to 1∶390 011,from 1∶697 002 to 1∶1 145 826,and from 1∶684 109 to 1∶1 067 317,respectively.The residual risks of HCV and HIV after NAT were 1∶22 369 329 and 1∶6 639 965,respectively,which were significantly reduced by 21.5-fold and 16.9-fold,and decreased steadily during the study period.Among the HBV-DNA(+)donors,61.8%(68/110)were RDs,and the residual risk was 1∶65 350.Conclusion This study demonstrates the remarkable effectiveness of introducing nucleic acid amplification technology(NAT)in reducing the residual risk of HBV,HCV,and HIV,particularly for HCV and HIV.The residual risk for HBV remains higher compared to HCV and HIV due to the discovery of occult HBV infections(OBI).Therefore,a crucial step toward further reducing this residual risk is the use of more sensitive reagents and detection platforms.Furthermore,implementing effective long-term incentive mechanisms and strategic planning to increase the proportion of repeat donors(RDs)is critical for enhancing transfusion safety.

Objective To explore the mechanism of Bushen Zhupai Decoction in treating ovarian fibrosis in polycystic ovary syndrome(PCOS)model rats based on IL-17/TRAF6/NF-κB signaling pathway.Methods Totally 60 SPF grade female SD rats were randomly divided into blank group,model group,Yousiyue group and TCM low-,medium-and high-dosage groups,with 10 rats in each group.The PCOS model was replicated by gavage of 1 mg/kg letrozole for 21 days.The Yousiyue group was given a 10 mg/kg solution of drospirenone ethinylestradiol tablets by gavage,TCM low-,medium-and high-dosage groups were given 8.82,17.64 and 35.28 g/kg of Bushen Zhupai Decoction by gavage,once a day for 28 consecutive days.HE and Masson staining were used to observe the morphology of ovarian tissue and ovarian fibrosis,the contents of serum IL-17,IL-18 and IL-1β were detected by ELISA,the mRNA expression of IL-17,TRAF6,NF-κB p65 and TGF-β1 in ovarian tissue were determined by RT-qPCR,the protein expression of TRAF6,NF-κB p65,TGF-β1,α-SMA,E-cadherin and the positive expression of IL-17RA,TRAF6,NF-κB p65,TGF-β1 and α-SMA in ovarian tissue were detected by Western blot and immunohistochemical staining respectively.Results Compared with the blank group,the body mass,ovarian mass and ovarian index significantly increased of rats in model group,with follicular cystic dilation,thinning of granulosa cell layer,and significant increase in fibrosis positive range(P<0.01),the serum contents of IL-17,IL-18 and IL-1β significantly increased(P<0.01),the expressions of IL-17,TRAF6,NF-κB p65,TGF-β1 mRNA and IL-17RA,TRAF6,NF-κB p65,TGF-β1 and α-SMA proteins significantly increased(P<0.01,P<0.05),the expression of E-cadherin protein significantly decreased(P<0.01).Compared with the model group,the ovarian index of rats in Yousiyue group and TCM medium-and high-dosage groups significantly decreased(P<0.01,P<0.05),the rats in TCM high-dosage group showed dominant follicles,increased thickness of granulosa cell layer,and significantly reduced fibrosis positive range(P<0.01),the serum contents of IL-17,IL-18 and IL-1β significantly decreased in Yousiyue group and TCM low-,medium-and high-dosage groups(P<0.01),the mRNA expressions of IL-17,TRAF6,NF-κB p65,TGF-β1,and the protein expressions of IL-17RA,TRAF6,NF-κB p65,TGF-β1 and α-SMA in ovarian tissue significantly decreaed in TCM high-dosage group(P<0.01,P<0.05),the expression of E-cadherin protein significantly increased(P<0.01).Conclusion Bushen Zhupai Decoction can decrease the body mass,improve the ovarian index,decrease the expressions of inflammatory factors and improve the status of ovarian fibrosis in PCOS rats.The mechanism may be related to the regulation of IL-17/TRAF6/NF-κB signaling pathway.

Objective: Diaphragm is the common site of metastasis in advanced ovarian cancer.Diaphragmatic surgery is necessary to achieve complete resection. Relative complications also pose challenges to perioperative management. This study aims to explore the influencing factors and management strategies for perioperative complications of diaphragm surgery. Methods: This study retrospectively included 396 patients who underwent diaphragmatic surgery for advanced ovarian cancer at Fudan University Shanghai Cancer Center from July 2015 to June 2022. Diaphragm surgical methods were classified, and perioperative complications were regarded according to Memorial Sloan Kettering Cancer Center criteria.Clinical characteristics and perioperative complications were analyzed to find correlations to establish the nomogram. Results: Among the 396 patients, 163 patients (41.2%) suffered from perioperative complications. Pleural effusion (33.1%) and pneumothorax (5.3%) were the most commonly reported. Patients with longer surgery duration (>3 hours) (p=0.003) and who underwent diaphragmatic incision surgery (p=0.004) had a higher incidence of postoperative complications. The incidence of postoperative pleural effusion was significantly higher in patients who underwent diaphragm full-thickness resection (49.3%) than diaphragmatic stripping (29.5%) (p=0.001), and patients who underwent diaphragm full-thickness resection are more likely to require drainage (p=0.001). Multi-variate analyses showed that stage IV tumor, long operation time, and diaphragm full-thickness resection are associated with postoperative pleural effusion. Conclusion Pleural effusion is the most common complication of diaphragmatic surgery in patients with ovarian cancer. Routine placement of prophylactic chest tubes is not appropriate for all patients undergoing diaphragmatic surgery. Our nomogram could help to predict its risk and indicate prophylactic management.

Objective:To investigate the clinical characteristics of left-sided infective endocarditis (IE) without underlying valvular heart diseases (VHD).Methods:This was a retrospective study. Clinical data of 206 patients with left-sided IE (age: (50.4±16.1) years; 144 males (69.9%)) discharged from Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from June 2011 to May 2021 were retrospectively analyzed, including 129 cases with underlying VHD (IE+VHD group) and 77 cases without underlying VHD (IE group). The 6-month survival rate of patients after discharge was analyzed with Kaplan-Meier survival curve; and the 6-month survival rates of the patients with different sizes of endocardial vegetation and different treatment modalities in the IE group were further analyzed with log-rank method.Results:The proportions of patients with age ≥65 years old, arrhythmia and aortic valve involvement, and the in-hospital mortality in the IE group were significantly lower than those in the IE+VHD group ( P<0.05). However, the proportion of patients with fever and speech vague/limb movement disorder/headache, those with mitral valve involvement in the IE group were significantly higher than those in the IE+VHD group ( P<0.05). The median value of C-reactive protein (CRP) in the IE group was significantly higher than that in the IE+VHD group ( P<0.05). Nevertheless, the median value of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in the IE group was significantly lower than that in the IE+VHD group ( P<0.05). There were as no significant differences in the positive rates of bacterial/fungal blood cultures and the proportion of patients with mitral and aortic valve involvement of endocardial vegetation between the two groups (all P>0.05). Kaplan-Meier survival curve analysis showed that there was no significant difference in 6-month survival rate of patients between the IE group and IE+VHD group (88.7% vs. 93.6%, log-rank χ2=0.887, P=0.346). In the IE group, the 6-month survival rate after discharge in patients with maximum diameter of vegetation ≤10 mm was higher than that in patients with maximum diameter of vegetation >10 mm (96.3% vs. 80.7%, log-rank χ2=4.111, P=0.043). There was no significant difference in 6-month survival rate between patients treated with antibiotics combined with surgery and those treated with antibiotics alone (96.2% vs. 78.6%, log -rank χ 2=2.976, P=0.084). Conclusion:Compared to left-sided IE patients with underlying VHD, patients without underlying VHD are likely to have a younger age, more mitral valve involvement and lower in-hospital mortality; for those patients with maximum diameter of vegetation ≤10 mm there is a higher survival rate, and antibiotics combined with surgery may help to improve the survival rate.

Objective:To evaluate the effectiveness of nursing interventions based on self-efficacy theory in patients with primary glaucoma undergoing scleral flap suture trabeculectomy.Methods:A convenience sampling method was used to select 350 patients with primary glaucoma undergoing scleral flap suture trabeculectomy admitted to the Department of Ophthalmology at the First Affiliated Hospital of Zhengzhou University from October 2021 to December 2023. Participants were randomly divided into a control group ( n=175) and an intervention group ( n=175) using a random number table. The control group received routine nursing care, while the intervention group received nursing interventions based on self-efficacy theory for a duration of three months. Visual status (visual acuity and intraocular pressure), self-management behaviors, and vision-related quality of life were compared between the two groups before and after the intervention. Results:After the intervention, the intervention group had significantly better visual acuity and lower intraocular pressure compared to the control group (both P<0.05). Scores across all dimensions of the Glaucoma Self-Management Questionnaire were significantly higher in the intervention group than in the control group, while scores on the 25-item National Eye Institute Visual Function Questionnaire were significantly lower (both P<0.05) . Conclusions:Nursing interventions based on self-efficacy theory are effective in improving visual acuity and reducing intraocular pressure, enhancing self-management behaviors, and improving vision-related quality of life in patients with primary glaucoma undergoing scleral flap suture trabeculectomy.
