Observational Study
A cross-sectional study of the association between blood cadmium and mortality among adults with myocardial infarction.
Cadmium (Cd) plays a key role in the occurrence of myocardial infarction (MI). We aimed to explore the association between blood Cd levels and all-cause mortality of MI on the basis of the National Health and Nutrition Examination Survey databases. This study included 800 adults with MI to obtain blood Cd concentrations and their follow-up information. ⋯ Grouped patients by turning point into 2 groups, Kaplan-Meier analysis showed that the low-concentration group had a lower death risk than the high-concentration group. Subgroup analysis revealed that the prognostic effect of Cd was more pronounced in patients with former smoking history, and receiver operating characteristic curve showed that blood Cd had a better-predicting function in patients with MI. Blood Cd levels were significantly related to all-cause mortality in patients with MI, especially in patients with Cd < 1.06 μg/L.

Lung cancer is a common malignant tumor with low cure rate. It has an easy recurrence and metastasis. ⋯ The cell viability rate was detected by cell counting kit-8, cell invasion ability was detected with Transwell, cell apoptosis and cell cycle was determined by flow cytometry, and the expression of GLI3 was detected using quantitative polymerase chain reaction and Western blot, to verify the effect of the interaction between miR-200c-3p and GLI3 on the cell activities. miR-200c-3p overexpression could inhibit cell viability and invasion, promote apoptosis, induce G0/G1 arrest, and inhibit cell division. GLI3 overexpression could reverse the miR-200c-3p inhibition on cell cycle, reduce the number of cells in the G0/G1 phase and increase the number of cells in the S phase. miR-200c-3p overexpression in A549 cells could inhibit cell viability and invasion, and promote apoptosis. miR-200c-3p could target GLI3 to regulate cell cycle and inhibit cell proliferation.

Sedentary behavior (SB) has been linked in the past by observational studies to gastrointestinal illnesses, although the exact cause of the link is still unknown. To deal with this problem, we carried out a Mendelian randomization (MR) study to thoroughly examine the connection between SB and common gastrointestinal illnesses. We selected instrumental variables representing the SB from the UK Biobank study, including watching television viewing, playing computer, and driving. ⋯ The replication analysis confirms the same conclusion. The results of this study demonstrate a causal relationship between cachexia and genetically predicted SB. To further understand the underlying pathogenic mechanisms at play, more study is required.

This study aimed to evaluate the effectiveness of N-acetylcysteine (NAC) in preventing complex regional pain syndrome type 1 (CRPS-1) by reducing proinflammatory cytokines and oxidative stress markers in patients with distal radius fractures. A retrospective single-center study at Bursa City Hospital involves patients over 50 years of age with distal radius fractures treated between January 2021 and December 2023. A total of 60 patients (mean age, 62.8 ± 5.1 years; 26 males and 34 females) were analyzed. ⋯ NAC significantly reduced end-point levels and changes in IL-6 (P < .001), TNF-α (P < .001), and IL-1 (P = .038) and improved oxidative stress markers, showing higher TAS (P < .001), lower TOS (P < .001), and oxidative stress index (P < .001) compared with controls. NAC significantly reduced the risk of developing CRPS-1 by decreasing levels of proinflammatory cytokines and oxidative stress. This study highlights NAC's potential as a preventive treatment for CRPS-1 and emphasizes the importance of early intervention.

Construction and validation of a predictive model for preoperative lower extremity deep vein thrombosis risk in elderly hip fracture patients: An observational study.
The aim of this study was to identify independent risk factors for preoperative lower extremity deep vein thrombosis (DVT) in elderly hip fracture patients and to construct a nomogram prediction model based on them. We collected clinical data from elderly hip fracture patients from Ya'an Hospital of Traditional Chinese Medicine (2021-2023), and used univariate and multivariate logistic regression analyses to identify independent risk factors for preoperative DVT. In this way, a nomogram prediction model was established. ⋯ Of the 223 elderly hip fracture patients, 23 (10.31%) developed DVT of the lower extremities before surgery. A total of 6 variables were identified as independent risk factors for preoperative lower extremity DVT in elderly hip fracture patients by logistic regression analysis: age > 75 years (OR = 1.932; 95% CI: 1.230-3.941), diabetes mellitus (OR = 2.139; 95% CI: 1.149-4.342), and prolonged duration of disease (OR. 2.535; 95% CI: 1.378-4.844), surgical treatment (OR = 1.564; 95% CI: 1.389-3.278), D-dimer > 0.5 mg/L (OR = 3.365; 95% CI: 1.229-7.715) fibrinogen > 4 g/L (OR = 3.473; 95% CI: 1.702-7.078). The constructed nomogram model has high accuracy in predicting the risk of preoperative DVT in elderly hip fracture patients, providing an effective tool for clinicians to identify high-risk patients and implement early intervention.
