Background: and Purpose Ruptured intracranial aneurysms (RIA) are associated with a mortality rate of up to 40% in the Chinese population, highlighting the critical need for targeted treatment interventions for at-risk individuals. Although the impact of aldehyde dehydrogenase 2 (ALDH2) gene mutations on susceptibility to intracranial aneurysms (IA) is well documented, the potential connection between ALDH2 rs671 single-nucleotide polymorphism (SNP) and RIA remains unexplored. Given the increased prevalence of ALDH2 gene mutations among Chinese Han individuals, it is clinically relevant to investigate the link between ALDH2 rs671 SNP and IA rupture. Methods: A prospective study was conducted on 546 patients diagnosed with IA to investigate the association between ALDH2 rs671 SNP and the risk of IA rupture. Results: The ALDH2 rs671 SNP (ALDH2*2) was significantly more prevalent in patients with unruptured IA (UIA) than in those with RIA (32.56% vs. 18.58%, P=0.004). Multivariate logistic regression analysis revealed that people with the ALDH2 mutation (ALDH2*1/*2 and ALDH2*2/*2 gene type) had a significantly reduced odds ratio (OR=0.49; 95% confidence level [CI] 0.27–0.88; P=0.018) for RIAs. Age-specific subgroup analysis indicated that the ALDH2 mutation provided a stronger protective effect in individuals aged 60 years and above with IA compared to those under 60 years old (OR=0.38 vs. OR=0.52, both P<0.05). Conclusion The incidence of RIA was significantly higher in individuals with a normal ALDH2 gene (ALDH2*1/*1) than in those with an ALDH2 rs671 SNP (ALDH2*1/*2 or ALDH2*2/*2). ALDH2 rs671 SNP may serve as a protective factor against RIA in the Chinese Han population.

Objective:To investigate the clinical characteristics of omphalocele, and to assess the risk factors associated with adverse outcomes.Methods:A retrospective cohort study was conducted. Clinical data of 224 patients diagnosed with omphalocele, who were hospitalized at Children′s Hospital, Zhejiang University School of Medicine from January 2013 to December 2022, were collected. Based on their discharge outcomes, the patients were classified into 2 groups: favorable outcomes and unfavorable outcomes. Chi-square test or continuity correction χ2 test or Fisher exact probability method, and Mann-Whitney U test were used for intergroup comparisons. Logistic regression analysis was performed to identify risk factors associated with adverse outcomes in omphalocele. Results:Among the 224 patients with omphalocele, 126 were male. A total of 208 patients (92.9%) had favorable outcomes, while 16 patients (7.1%) had unfavorable outcomes. In the unfavorable outcomes group, 14 patients had giant omphaloceles, while 100 patients had giant omphaloceles in the favorable outcomes group. The rates of herniation of more than two intra-abdominal organs in the hernial sac, congenital heart defects, patent ductus arteriosus, pulmonary hypertension, sepsis and infection of the hernial sac, were all higher in the unfavorable outcomes group compared to the favorable outcomes group (all P<0.05). Patients with unfavorable outcomes had longer mechanical ventilation time, duration of oxygen use, duration of parenteral nutrition, hospital stays, and higher rates of parenteral nutrition-associated cholestasis compared to those with favorable outcomes (all P<0.01). Multivariate Logistic regression analysis indicated that pulmonary hypertension ( OR=9.39, 95% CI 1.20-73.32), sepsis ( OR=8.59, 95% CI 1.32-55.86), and congenital heart defects ( OR=6.55, 95% CI 1.11-38.73) were all independent risk factors for adverse outcomes in omphalocele (all P<0.05). Conclusions:Infants with omphalocele are prone to complications such as cardiovascular malformations, infections, and pulmonary hypertension. Adverse outcomes in omphalocele are associated with pulmonary hypertension, sepsis, and congenital heart defects.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective:To explore the latent profile types of capability-opportunity-motivation-behavior in stroke patients and analyze the influencing factors of different latent profiles.Methods:From January to October 2023, totally 596 stroke patients from the Neurology Department of five ClassⅢ Grade A hospitals in Henan Province were selected by stratified random sampling. The patients were surveyed using a general information questionnaire, the Stroke Prevention Knowledge Questionnaire (SPKQ), the Social Support Rating Scale (SSRS), the WHO's Quality of Life Questionnaire- Brief Version (WHOQOL-BREF), the Short Form Health Belief Model Scale (SF-HBMS), and the Health Promoting Lifestyle ProfileⅡ (HPLPⅡ). Latent profile analysis was used to classify the capability-opportunity-motivation-behavior characteristics of stroke patients, and multiple logistic regression was conducted to explore the influencing factors of different latent profiles.Results:Three latent profiles of capability-opportunity-motivation-behavior in stroke patients were identified, including low capability-opportunity-motivation-behavior with high health beliefs (32.4%, 193/596), moderate capability-opportunity-motivation-behavior with insufficient health beliefs (47.5%, 283/596), and high capability-opportunity-motivation-behavior with lack of social support (20.1%, 120/596). Multiple logistic regression analysis showed that educational level, smoking history, family history, body mass index, and Charlson Comorbidity Index score were influencing factors of different latent profiles ( P<0.05) . Conclusions:Stroke patients exhibit distinct classifications of capability-opportunity-motivation-behavior. Targeted interventions should be conducted based on the characteristics of each category to improve health behavior management outcomes in patients.

Objective:This study evaluates the accessibility and equity of healthcare resources in deep mountain,shallow mountain,and plain suburban areas,taking Huairou,Mentougou,and Tongzhou districts of Beijing as examples,to identify factors contributing to the imbalance in resource allocation.Methods:Accessibility of healthcare services in the sample areas was measured using village-level health survey data and the Two-Step Floating Catchment Area(2SFCA)method.Equity of resource allocation was assessed using the Gini coefficient among other methods.Factors influencing imbalance were identified using the Geodetector and Spatial Lag Model.Results:The average accessibility scores for Huairou,Mentougou,and Tongzhou were 202.06,179.68,and 187.02,respectively.The Gini coefficients were 0.48,0.37,and 0.24,respectively.GDP,population density,and altitude were significant factors affecting accessibility.Conclusions and Suggestions:In Beijing,both plain and mountainous rural areas exhibited a spatial clustering of healthcare accessibility,higher near the city and lower in the suburbs,with plains performing better than mountains.Healthcare equity was ranked as plains>shallow mountains>deep mountains.Policies covering full healthcare services improved equity.It is recommended to strengthen the construction of village healthcare facilities and medical teams,improve the linkage of medical services at all rural levels,and enhance the willingness of villagers to seek primary care.Furthermore,gradual improvement of transportation and internet infrastructure is suggested to enhance the accessibility of online and offline medical services for villagers.

Objective:To compare transperineal prostate biopsy(TPB)with transrectal ultrasound-guided prostate biopsy(TRUSB)in detection of clinically significant prostate cancer(csPCa)and insignificant PCa(insPCa).Methods:We conducted a prospective randomized clinical study on 279 patients receiving TPB(n=144)or TRUSB(n=135)from January 2022 to January 2023,and compared the detection rates of csPCa and insPCa between the two groups.Results:The detection rate of PCa was signifi-cantly higher in the TPB than in the TRUSB group(37.50％vs 28.15％,P=0.026).There were no statistically significant differ-ences between the TPB and TRUSB groups in the detection rates of insPCa(6.94％[n=10]vs 4.45％[n=6],P＞0.05)and csPCa(30.56％[n=44]vs 23.70％[n=32],P＞0.05),nor in the detection rate of csPCa between different groups of age,PSA concentration and prostate volume(P＞0.05).No statistically significant differences were observed between the TPB and TRUSB groups either in the positive rate of biopsy punctures([16.44±2.86]％vs[12.48±2.39]％,P＞0.05)or in the bi-opsy-related complications of urinary retention,urinary tract infection,hematuria and rectal bleeding(P＞0.05).Conclusion:TPB is more effective than TRUSB in detection of PCa,but there is no statistically significant difference between the two approaches in the detection rates of csPCa and insPCa.

Objective:To summarize the distributional characteristics of postoperative occurrence of multi-drug resistant organism (MDRO) infections and their risk factors in simultaneous pancreas-kidney transplantation (SPK) recipients and examine the impact of MDRO infections on the survival of SPK recipients.Method:From January 2016 to December 2022, the relevant clinical data were retrospectively reviewed for 218 SPK recipients. The source of donor-recipient specimens and the composition percentage of MDRO pathogens were examined. According to whether or not MDRO infection occurred post-transplantation, they were assigned into two groups of MDRO (98 cases) and non-MDRO (120 cases). The clinical data of two groups of donors and recipients were analyzed. And the risk factors for an onset of MDRO infection were examined by binary Logistic regression. The survival rate of two recipient groups was compared by Kaplan-Meier method.Result:A total of 98/218 recipients (45%) developed MDRO infections. And 46 (46.9%) of sputum and 34 (34.7%) of urine were cultured positively and 49 (50%) pathogens expressed extended spectrum beta-lactamase. There were pneumonia (46 cases, 46.9%), urinary tract infections (34 cases, 34.7%), abdominal infections (16 cases, 16.3%) and bloodstream infections (2 cases, 2.0%). Univariate regression analysis revealed that length of renal failure ( P=0.037), length of hospitalization ( P<0.001), length of antibiotic use ( P<0.001), novel antibiotics ( P=0.014), albumin ( P<0.001) and leukocyte count ( P<0.001) were risk factors for an onset of MDRO infections. The results of multifactorial regression indicated that low albumin ( OR=0.855, 95% CI: 0.790~0.925, P<0.001) and leukopenia ( OR=0.656, 95% CI: 0.550~0.783, P<0.001) were independent risk factors for an onset of MDRO infections. The survival rates of recipients in MDRO group at Year 1/3 post-operation were 92.9% (91/98) and 89.8% (88/98). And the survival rate of recipients in non-MDRO group was 96.7% (116/120) at Year 1/3 post-operation. Inter-group difference was not statistically significant in 1-year survival rate of two recipient groups ( P=0.201); statistically significant inter-group difference in 3-year survival rate between two recipient groups ( P=0.041) . Conclusion:Low albumin and leukopenia are risk factors for MDRO infection. Infection with MDRO has some impact on the survival of recipients.
