Objective:To investigate associations of plasma D-dimer and fasting blood glucose with the outcome in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to the Department of Neurology, Dagang Hospital, Binhai New Area, Tianjin from January 2018 to December 2023 were included retrospectively. The demographic characteristics, baseline clinical data, and laboratory findings were collected. According to the modified Rankin Scale score at 3 months after onset, the patients were divided into a good outcome group (0-2) and a poor outcome group (>2). Multivariate logistic regression analysis was used to determine the independent related factors for the outcome in patients with AIS. Results:A total of 1 967 patients were enrolled, including 1 287 males(65.4%), aged 67.80±11.58 years. The median baseline National Institutes of Health Stroke Scale (NIHSS) score was 4 (interquartile range, 2-7). One thousand five hundred and twenty-three patients (77.4%) had good outcome, and 444 (22.6%) had poor outcome. Univariate analysis showed that age, baseline systolic blood pressure, baseline NIHSS score, fasting blood glucose and D-dimer, as well as the proportion of patients with a history of ischemic heart disease, previous stroke or transient ischemic attack in the poor outcome group were significantly higher than those in the good outcome group (all P<0.05). Multivariate logistic regression analysis showed that older age (odds ratio [ OR] 1.286, 95% confidence interval [ CI] 1.137-1.458; P=0.037), complicated with ischemic heart disease ( OR 1.598, 95% CI 1.024-2.227; P=0.046), higher baseline systolic blood pressure ( OR 1.011, 95% CI 1.002-1.045; P=0.037), higher baseline NIHSS score ( OR 1.432, 95% CI 1.132-1.587; P<0.001), higher baseline D-dimer ( OR 4.001, 95% CI 1.839-8.703; P=0.040), and higher fasting blood glucose ( OR 1.175, 95% CI 1.078-1.282; P=0.045) were independently associated with the poor outcome. Conclusion:Higher D-dimer and fasting blood glucose are associated with the poor outcome in patients with AIS.

OBJECTIVE To explore the time windows for postoperative pneumonia in patients undergoing different surgeries,providing evidence-based references for optimizing infection monitoring and prevention and control strategies.METHODS Sociodemographic characteristics,clinical information and surgical details of 263 patients with postoperative pneumonia from four different types of medical institutions between Jan.2019 and Dec.2024 were retrospectively collected.The time windows for postoperative pneumonia in patients undergoing different surgeries were analyzed.RESULTS There were no statistically significant differences in the time windows for post-operative pneumonia among groups in terms of sociodemographic factors and underlying diseases.However,sta-tistically significant differences were observed in the time windows for postoperative pneumonia based on surgery type,incision type,surgical approach and surgery duration(P＜0.05).The average time for the onset of postop-erative pneumonia in 263 patients was 2.00(1.00,7.00)days.The postoperative time windows varied for sur-geries involving different systems.The peak incidence occurred on day 0(16 cases)and day 1(17 cases)af-ter neurological surgery,while the peak incidence for digestive system and orthopedic surgeries was on day 1.The time span for the onset of pneumonia after skin surgeries was wider(0-53 days postoperatively)without a clear peak.In addition,33.33％of cardiovascular system surgery cases developed pneumonia 10 days postoperatively.There were also significant time differences in the diagnostic elements of postoperative pneumonia,with fever and abnormal white blood cell counts appearing earlier(median appearance time length:4.00 days)than lung imaging changes(median appearance time length:7.00 days).CONCLUSIONS This study demonstrates significant time differences in the on-set of postoperative pneumonia and confirms the significant spatiotemporal heterogeneity in the diagnostic elements of postoperative pneumonia.These findings provide a quantitative basis for developing dynamic,surgery-type-spe-cific monitoring protocols and prevention and control measures for postoperative pneumonia.

Objective:To evaluate the efficacy of hybrid closed-loop insulin delivery system (CLS) in glycemic control in young children with type 1 diabetes mellitus (T1DM).Methods:This retrospective observational self-controlled study analyzed data from 14 children (aged 3-9 years) with T1DM treated at the Endocrinology and Metabolism Department of Anhui Provincial Children′s Hospital between August 2021 and February 2024. All the patients had undergone continuous subcutaneous insulin infusion (commonly known as insulin pump therapy) with continuous glucose monitoring system (CGMS) for at least 4 weeks and CLS for over 6 months. Data collected included age, sex, body mass index (BMI), diabetes duration, duration of insulin pump use, baseline glycated hemoglobin (HbA1C), and pre-and post-treatment glycemic metrics. Based on the duration of combined CLS therapy, groups were divided as follows: baseline (before combined CLS therapy), 0-<4 weeks, 4-<8 weeks, 8-<12 weeks, 12-<24 weeks. Independent sample t-test and ANOVA were used to compare intergroup and multigroup differences, respectively, in glycemic levels before and after hybrid CLS therapy. Results:Among the 14 pediatric patients, 8 were male and 6 were female. Their age was (6.5±0.5) year old, BMI was (16.1±1.3) kg/m2, duration of diabetes was (20.1±2.6) months, duration of CGMS insulin pump use was (13.8±2.6) months, and baseline HbA1C was (10.2±0.8)%. One-way ANOVA revealed that hybrid CLS therapy significantly improved glycemic control, compared to pre-treatment, at 6 months follow-up, the following outcomes were observed: increased time-in-range (TIR), reduced time in hyperglycemia and hypoglycemia, lower HbA1C and mean glucose level, improved daytime TIR, and decreased mean glucose levels at fasting, postprandial (three meals), and bedtime (22:00), and scores on the pediatric quality of life inventory significantly increased ( F=3.16, 2.94, 2.56, 13.84, 2.36, 7.00, 40.48, 115.90, 192.50, 122.70, 75.55, t=11.00, all P<0.05). Conclusions:Compared to baseline insulin pump therapy, hybrid CLS improves glycemic control and quality of life in young children with T1DM, while reducing the risk of hypoglycemia over a 6-month treatment period.
