Observational Study
Risk-factor analysis of the proximal tibia morphology for secondary ipsilateral injury after anterior cruciate ligament reconstruction: A retrospective cross-sectional study.
Many studies have reported the risk factors associated with primary anterior cruciate ligament (ACL) injury. However, few studies have focused on the bony morphology of secondary ipsilateral injury after ACL reconstruction. This study aimed to investigate the morphological risk factors of the proximal tibia contributing to secondary ipsilateral injury after ACL reconstruction. ⋯ The cutoff value of the LTPS was 8.8°, with a sensitivity of 91.7% and a specificity of 81.2%. The LTPS could be a unique predictor of secondary ipsilateral injury after ACL reconstruction. Orthopedists should implement effective measurements during primary reconstruction when the LTPS is >8.8°.

Association of high serum β2-microglobulin levels with poor functional outcomes in patients with acute ischemic stroke: A cohort study.
We evaluated the association between serum β2-microglobulin (β2M) levels and prognosis in patients with acute ischemic stroke (AIS) and determined whether the association was affected by any clinical variables. This prospective study included 533 patients with AIS who were admitted to the Hospital of Nanhua Affiliated with the University of South China for treatment from June 1, 2021, to July 31, 2022. Using multiple regression modeling, the association between serum β2M levels and poor functional outcomes-which were classified as being modified Rankin Scale scores of 3 to 6 (composite score of death and major disability), 3 to 5 (major disability), and 6 (death)-were assessed 3 months after stroke onset. ⋯ The risk prediction for the combined outcome of death and major disability improved after incorporating β2M levels into models that included conventional risk factors. Subgroup analysis revealed a significant impact on the association between serum β2M levels and poor functional outcomes only in patients with AIS whose time from onset to hospitalization was <12 hours (P for interaction < .05). Elevated serum β2M levels were associated with poor functional outcomes in patients with AIS, possibly affected by the time from onset to hospitalization.

We evaluated the efficacy of indocyanine green fluorescence imaging compared to that of traditional nanocarbon dyes in assessing peri-intestinal lymph node metastasis in patients with colorectal cancer, which is a key prognostic factor. The relationship between indocyanine green fluorescence imaging and histopathological outcomes in patients with colon cancer has also been explored. A retrospective analysis was conducted on 30 patients with colon cancer (from May to October 2023) confirmed by surgical pathology. ⋯ All P values were two-sided, with P < .05 indicating statistical significance. Lymph nodes with malignant intestinal tumor metastasis displayed weaker ICG fluorescence than did nonmetastatic nodes. Combining ICG and nanocarbon staining techniques enhances intraoperative lymph node dissection and postoperative analysis, indicating their potential utility in colorectal cancer surgery.

This study aims to assess the associations among students' perceptions of climate change, university social responsibility (USR), and environmental sustainability practices at a medical university. It also aims to identify the factors associated with these elements. A cross-sectional self-report study was conducted with a total sample of 416 undergraduate students from a medical university in Taiwan during October 2019. ⋯ In addition, school year (non-freshmen vs freshmen, -1.64 [0.65]) and environmental sustainability practices (per 1-point increase, 0.23 [0.06]) were associated with the total score of students' perception of USR (R-square = 6.57%). Promoting environmental sustainability among university students can be achieved by implementing USR-oriented courses or activities. Our research is pioneering in investigating and discussing the perceived USR and environmental sustainability practices among university students in Taiwan.
