Oxidative Balance Score Associated with Osteoporosis in Younger Women: A Cross-Sectional Analysis of the National Health and Nutrition Examination Survey 2013-2014 and 2017-2018 Data.

Objective: To explore the association between oxidative balance score (OBS) and osteoporosis risk, as well as to identify the specific population group.

Methods: In this cross-sectional study, we included the data of 5,413 participants using the National Health and Nutrition Examination Survey of 2013-2014 and 2017-2018. Restricted cubic spline (RCS) curves, logistic regression models, trend tests, and stratification analyses were used to evaluate the association between the OBS and osteoporosis risk.

Relationship between admission blood urea nitrogen levels and postoperative length of stay in patients with hip fracture: A retrospective study.

To investigate the relationship between admission blood urea nitrogen (BUN) levels and postoperative length of stay (LOS) in hip fracture (HF) patients. This retrospective study retrieved related data from the MIMIC-IV database, of which the laboratory variables were taken preoperatively. The patients were divided into 4 groups according to the BUN quartile levels.

Nomogram Models Based on the Gene Expression in Prediction of Breast Cancer Bone Metastasis.

Objective: The aim of this study is to design a weighted co-expression network and build gene expression signature-based nomogram (GESBN) models for predicting the likelihood of bone metastasis in breast cancer (BC) patients.

Methods: Dataset GSE124647 was used as a training set, while GSE16446, GSE45255, and GSE14020 were taken as validation sets. In the training cohort, the limma package in was adopted to obtain differentially expressed genes (DEGs) between BC nonbone metastasis and bone metastasis patients, which were used for functional enrichment analysis.

[Establishment of finite element model of anterior cervical transpedicular system for reconstruction of cervical stability after subtotal resection of two segments of lower cervical spine].

Objective: To establish the fixation model of anterior cervical transpedicular system (ACTPS) after subtotal resection of two segments of lower cervical spine(C-C) in order to provide a finite element modeling method for anterior cervical reconstruction.

Methods: The CT data of the cervical segment (C-T) of a 30-year-old adult healthy male volunteer was collected. Used Mimics 10.
