ObjectiveTo investigate the value of the change trend of lactic acid level 24 h after operation in predicting the complications of upper gastrointestinal ulcer perforation. MethodsA total of 167 patients with upper digestive tract ulcer perforation who underwent surgical treatment in Shougang Hospital of Peking University from March 2021 to June 2023 were selected as the study objects, and were divided into mild to moderate group (n=117) and severe group (n=50) according to the severity of the disease. General data and lactic acid levels in 24 h after surgery were compared between the two groups. In addition, according to whether the patients had complications or not, they were divided into a group without complications (n=119) and a group with complications (n=48). The general data of the two groups were compared. A combined model was constructed, and Cox regression model was used to analyze the relationship between the change of lactic acid level at 24 h after operation and the complications of infection. Logistic regression model combined with restricted cubic spline model was used to analyze the dose-response relationship between lactic acid level and infection complications in patients with upper gastrointestinal ulcer perforation 24 h after operation. Log-binomial model was used to analyze the risk effect of complication types on lactic acid levels in patients with upper gastrointestinal ulcer perforation. ResultsAt 8, 16 and 24 h after operation, lactic acid levels in both groups (mild to moderate group and severe group) were significantly lower than before operation, and lactic acid level in mild to moderate group was significantly lower than that in severe group (P<0.05). Repeated measurement ANOVA showed that the time effect, intergroup effect and interaction effect of lactic acid levels were significantly different between the two groups (P<0.05). There were significant differences in exhaust time, postoperative hospital stay, C-reactive protein, lactic acid level and red blood cell distribution width between the complicated group and the uncomplicated group (P<0.05). The combined model showed that each longitudinal increase of 1 mmol/L in lactic acid level 24 h after operation, was associated with a 4% increased risk of infection complications. The limit cubic spline map showed that lactic acid level at 24 h after operation was 4.22 mmol/L as the critical point of the dose-response relationship in the infection complications of patients with upper gastrointestinal ulcer perforation. Log-binomial model analysis results showed that when lactic acid level ≥4.22 mmol/L, patients with upper gastrointestinal ulcer perforation in the complication group had the highest risk of abdominal infection. The risk ratios (95%CI) before and after adjustment were 2.09 (1.25, 2.64), 2.16 (1.28, 2.05) and 2.20 (1.32, 2.63) times of those in the uncomplicated group, and the risk ratios of different lactic acid levels were statistically significant before and after adjustment (P<0.05). ConclusionLactic acid level increased 24 h after operation in patients with upper gastrointestinal ulcer perforation is closely related to infection complications, and has a high predictive value for infection complications in patients with upper gastrointestinal ulcer perforation.
ObjectiveTo systematically review the adjuvant endocrine therapy adherence among Chinese patients with breast cancer. MethodsThe Cochrane Library, Web of Science, PubMed, EMbase, CINAHL, CNKI, VIP, WanFang Data and CBM were electronically searched to collect studies on adjuvant endocrine therapy adherence among Chinese patients with breast cancer from inception to September 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using Stata 16.0 software. ResultsA total of 24 studies were included. The results of meta-analysis showed that: the overall adherence rate of adjuvant endocrine therapy in Chinese breast cancer patients was 55.0% (95%CI 0.44 to 0.65), and a 5-year adherence rate was 54.4% (95%CI 0.46 to 0.63). Subgroup analysis showed that patients with good disease awareness, high education level, high monthly household income, living in cities, effective family support, no adverse drug reactions, high convenience of seeking medical treatment, regular review, health education, no comorbidities, and changes in medication type might have higher compliance. ConclusionThe adherence rate of adjuvant endocrine therapy in breast cancer patients in China is low. Adherence varies between sociodemographic characteristics, treatment, and social support for breast cancer patients.
Objective To compare clinical outcomes between the performed titanium locking plate and nickel-titanium memory alloy embracing fixator for the treatment of multiple rib fractures, and to select a better internal fixator for multiple rib fractures. Methods A total of 206 consecutive patients with multiple rib fractures were admitted to Department of Cardiothoracic Surgery in Beijing Luhe Hospital of Capital Medical University from October 2011 to September 2016. According to different treatment strategies, the patients were divided into 2 groups: a performed titanium locking plate group (a titanium plate group, n=105) and a nickel-titanium memory alloy embracing fixator group (an embracing fixator group, n=101). There were 82 males and 23 females with a mean age of 46.5±9.7 years ranging from 23 to 65 years in the titanium plate group, and 83 males and 18 females with a mean age of 44.7±10.3 years ranging from 19 to 63 years in the embracing fixator group. The preoperative data, curative outcomes, visual analogue scale (VAS) and postoperative complications were compared between the two groups. Results There was no statistical difference in the preoperative data between the two groups, and all patients successfully completed the operation. Compared with the embracing fixator group, the incision length and operation time were shorter, intraoperative bleeding and VAS score were less, and curative outcome was better in the titanium plate group. Conclusion The performed titanium locking plate has a great advantage in the clinic, which can be preferred.
