Predictors of Outcome After Traumatic Brain Injury: Experience at a Tertiary Healthcare Facility in Inner Mongolia, China.

BACKGROUND: Traumatic brain injury (TBI) is 1 of the leading causes of death in all age groups globally. Understanding TBI causative factors and early interventions that may result in poor outcomes plays an important role in decreasing the mortality and disability associated with TBI. METHODS: In this retrospective case-control study, we collected electronic case data from patients with TBI who visited our hospital between 2018 and 2022. We collected patient information from accident to discharge, and by using linear regression predicted factors influencing death from TBI. RESULTS: A total of 957 patients with a mean age of 56.4 ± 17.0 years and a Glasgow Coma Scale score of 12 ± 3.7 on admission were included in the study. Of the total, 54 patients died in the hospital. Multifactorial logistic regression showed that the Glasgow Coma Scale scores, degree of injury on admission, surgical treatment, and brainstem hemorrhage all had a significant effect on the survival status of the patients at discharge. CONCLUSIONS: Understanding the causes, patterns, and distribution of people with TBI in this study will benefit our country and others to develop policies, research, health management, and rehabilitation tools at the national level.

[The association between gingival cervicular fluid Interleukin-6 level, serum estradiol status and periodontitis in Uyghur postmenopausal women].

PURPOSE: The purpose of this investigation was to analyze by cross-sectional design the association between GCF IL-6 level, serum E2 level and common clinical measurements of periodontitis in Uyghur postmenopausal women. METHODS: 79 subjects within 5 years after menopause were enrolled in the study. 30 GCF samples were harvested from healthy sites, 49 GCF samples from chronic periodontitis sites. Clinical measurements of each tooth were recorded after obtaining GCF samples. GCF IL-6 and serum E2 levels were measured by radioimmunoassay (RIA). RESULTS: The mean concentration of GCF IL-6 from healthy sites was (1088.10+/-102.33)pg/ml.The mean concentration of IL-6 from chronic periodontitis sites was significantly higher than that of healthy sites (P<0.005). Positive correlation was found between GCF IL-6 level and clinical measurements (GI, PPD and CAL) (r=0.564, P<0.005; r=0.335, P<0.05; r=0.324, P<0.05). Clinical measurements and GCF IL-6 levels of chronic periodontitis subjects were not different between E2-deficient and E2-sufficient subjects. CONCLUSIONS: These findings suggest that there is lower IL-6 level in GCF from healthy sites; the increasing production of IL-6 may be associated with the initiation and progress of periodontitis. IL-6 may be a valuable indicator of the severity of periodontitis; E2 level is not associated with clinical measurements and GCF IL-6 level of chronic periodontitis of Uyghuy woman in early menopause.
