Objective To evaluate the long-term survival of patients with T1a-bN0M0 non-small cell lung cancer (NSCLC) after sublobar resection. Methods Patients with T1a-bN0M0 NSCLC who underwent sublobar resection from 2004 to 2015 were selected from the Surveillance, Epidemiology, and End Results (SEER) database, and divided into a segmentectomy group and a wedge resection group according to the resection method. After propensity-score matching at a ratio of 1:1, the overall survival (OS) and disease-specific survival (DSS) of patients were analyzed using Cox regression model, log-rank test, and restricted mean survival time (RMST). Results A total of 3262 patients were included in the study, including 1321 males and 1941 females, with a median age of 69.0 years. Among them, 2419 patients were in the wedge resection group and 843 patients were in the segmentectomy group. After matching, 843 pairs of patients were obtained. The results showed that the 10-year DSS rate (68.0% vs. 60.6%, P=0.011) and 10-year OS rate (40.8% vs. 37.0%, P=0.049) of the segmentectomy group were better than those of the wedge resection group, while there was no statistical difference in the 5-year DSS rate (82.9% vs. 79.5%, P=0.112) or 5-year OS rate (68.9% vs. 64.9%, P=0.096). Multivariate Cox regression analysis revealed that male gender [HR=1.54, 95%CI (1.28-1.86), P<0.001] and age [HR=1.02, 95%CI (1.01-1.03), P<0.001] were independent risk factors for DSS, while increased number of regional nodes dissected (RND) [HR=0.98, 95%CI (0.96-1.00), P=0.018] and segmentectomy [HR=0.82, 95%CI (0.68-0.98), P=0.030] served as protective factors. For OS, male gender [HR=1.54, 95%CI (1.35-1.75), P<0.001], age [HR=1.04, 95%CI (1.03-1.04), P<0.001], and histological subtypes of squamous cell carcinoma [HR=1.62, 95%CI (1.41-1.86), P<0.001] or large cell carcinoma [HR=1.64, 95%CI (1.07-2.52), P=0.023] were identified as independent risk factors, whereas increased RND was a protective factor [HR=0.98, 95%CI (0.97-0.99), P=0.002]. Surgical approach was not an independent prognostic factor for OS. Subgroup analysis showed that segmentectomy had a better 10-year OS-RMST in patients with adenocarcinoma (P=0.045), right lower lobe tumor (P=0.014), and tumor diameter ≤1.6 cm (P=0.006). Conclusion Increasing lymph node dissection during sublobar resection may improve prognosis. Compared with wedge resection, segmentectomy may improve the long-term DSS rate of patients with T1a-bN0M0 NSCLC.

BACKGROUND: Mild cognitive impairment (MCI) is common in atrial fibrillation (AF) patients and may develop earlier in those with multiple cardiovascular comorbidities, potentially impairing self-management and treatment adherence. This study aimed to characterize the prevalence and profile of MCI in AF patients, examine its associations with cardiovascular comorbidities, and assess how these comorbidities influence specific cognitive domains. METHODS: This cross-sectional study analyzed data from AF patients who underwent cognitive assessment between 2017 and 2021. Cognitive status was categorized as MCI or non-MCI based on the Montreal Cognitive Assessment. Associations between comorbidities and MCI were assessed by logistic regression, and cognitive domains were compared using the Mann-Whitney U test. RESULTS: Of 4136 AF patients (mean age: 64.7 ± 9.4 years, 64.7% male), 33.5% of patients had MCI. Among the AF patients, 31.2% of patients had coronary artery disease, 20.1% of patients had heart failure, and 18.1% of patients had hypertension. 88.7% of patients had left atrial enlargement, and 11.0% of patients had reduced left ventricular ejection fraction. Independent factors associated with higher MCI prevalence included older age (OR = 1.04, 95% CI: 1.03-1.05, P < 0.001), lower education level (OR = 1.51, 95% CI: 1.31-1.73, P < 0.001), hypertension (OR = 1.28, 95% CI: 1.07-1.52, P = 0.001), heart failure (OR = 1.24, 95% CI: 1.04-1.48, P = 0.020), and lower left ventricular ejection fraction (OR = 1.43, 95% CI: 1.04-1.98, P = 0.028). A higher CHA₂DS₂-VASc score (OR = 1.27, 95% CI: 1.22-1.33, P < 0.001; ≥ 2 points vs. < 2 points), and greater atherosclerotic cardiovascular disease burden (OR = 1.45, 95% CI: 1.02-2.08, P = 0.040; 2 types vs. 0 type) were linked to increased MCI risk. These above factors influenced various cognitive domains. CONCLUSIONS MCI is common in AF and closely associated with cardiovascular multimorbidity. Patients with multiple comorbidities are at higher risk, highlighting the importance of routine cognitive assessment to support self-management and integrated care.

Objective To explore the value of high density lipoprotein cholesterol(HDL-C)in predicting the risk of amputation in patients with diabetic foot(DF).Methods A total of 110 DF patients hospitalized in the First Affiliated Hospital of Baotou Medical College from August 2020 to June 2024 were selected as the study subjects,including 23 patients in amputation group and 87 patients in non-amputation group according to whether amputation.The related data of two groups were compared.Binary Logistic regression analysis was used to explore the influencing factors of amputation in DF patients,and receiver operating characteristic curve(ROC)was used to analyze and compare the predictive value of HDL-C combined with other possible risk factors for amputation outcome.Results A total of 110 patients were included in this study,and binary Logistic regression analysis showed that HDL-C,length of stay,uric acid,and lower extremity arterial disease were the influential factors for amputation in diabetic foot patients(P＜0.05).HDL-C combined with lower extremity arterial disease can improve the ability to predict the outcome of amputation.Conclusion HDL-C level is an influential factor in the amputation of DF patients,and has a certain predictive value for the amputation of DF patients.

Objective To study the compliance and influencing factors of inhalation therapy in patients with stable chronic obstructive pulmonary disease (COPD),and carry out patient education and management accordingly. Methods COPD patients were selected from respiratory clinic of Luodian Hospital of Baoshan District of Shanghai from June to December in 2021. Compliance and inhalation techniques were assessed with the Morisky Medication Adherence Scale and the ten-step inhalation technique, and the factors influencing compliance were analyzed. Results A total of 58 outpatients with COPD were included, in which 25 cases (43.1%) with moderate or above compliance. Univariate analysis showed that the patients with course of disease ≥5 years, COPD assessment test(CAT)≥10 points, used 2 inhalation devices and inhalation technique score ≥8 points had better compliance when compared with other patients (P<0.05). Conclusion Patient education and management should be carried out actively. The patients with course of disease<5 years, CAT<10 points should be highly concerned. The inhalation devices should be chosen according to the patients' condition. Training on the use of devices should be strengthened and regularly follow-up evaluation should be carried out.

This study summarizes the holistic nursing management of high-output stomas in three cases of refractory Crohn's disease following double stoma surgery.The nursing highlights encompassed management of high-output stomas(including assessment of high stoma output,use of octreotide ace-tate combined with Bifidobacterium and montmorillonite powder to reduce high stoma output,and dual stoma management),dynamic assessment of nutritional risk,stepped nutritional support,psychological intervention,and continued care at home.After treatment and nursing,the high stoma output in all three patients was effectively controlled,their nutritional status gradually improved,and they were dis-charged in an improved condition.

Transjugular intrahepatic portosystemic shunt(TIPS)is an important intervention for portal hypertension,and the degree of reduction in portal venous pressure is closely associated with the prognosis of patients.While a greater reduction in portal venous pressure may lead to more effective alleviation of portal hypertensive symptoms in cirrhotic patients,it also increases the risk of hepatic encephalopathy and liver failure.Therefore,appropriate control of the degree of reduction in portal venous pressure is essential for optimizing therapeutic outcomes.This article reviews the methods for measuring portal venous pressure,the factors affecting the reduction in portal venous pressure,the optimal range for reduction in different indications,and the impact of varying degrees of pressure reduction on complications,in order to provide guidance for improving the treatment outcome of TIPS and the prognosis of patients after surgery.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.
