Genetic evidence of the causal relationship between chronic liver diseases and musculoskeletal disorders.

Background: Chronic liver diseases constitute a major global public health burden, posing a substantial threat to patients' daily lives and even survival due to the potential development of musculoskeletal disorders. Although the relationship between chronic liver diseases and musculoskeletal disorders has received extensive attention, their causal relationship has not been comprehensively and systematically investigated.

This study utilized the Mendelian randomization (MR) approach to explore potential causal relationships between PUFAs and OA. The MR study was performed using GWAS summary statistics for PUFAs, encompassing omega-3 and omega-6 fatty acids, and for knee OA (KOA) and hip OA (HOA).

However, the specific pathological mechanisms are still ill-defined and controversial. The purpose of this study was to define potential diagnostic markers and evaluate immune cell infiltration in the pathogenesis of PVNS.

H3K9ac of TGFβRI in human umbilical cord: a potential biomarker for evaluating cartilage differentiation and susceptibility to osteoarthritis via a two-step strategy.

Overexpression of miR-335 inhibits the migration and invasion of osteosarcoma by targeting SNIP1.

MicroRNAs (miRNAs) are key regulators in the development and progression of osteosarcoma (OS). Based on our previous microarray data, we found that miR-335 expression was downregulated in OS tissue relative to normal tissue. Herein, we further found that miR-335 was downregulated in OS cell lines relative to the osteoblastic cell line hFOB 1.

Intravenous morphine titration vs. oral hydrocodone/acetaminophen for adults with lower extremity displaced fracture in an emergency department setting: A randomized controlled trial.

The objective of the present study was to test the hypothesis that intravenous morphine titration provides superior analgesia to oral hydrocodone/acetaminophen for patients with lower extremity displaced fracture in an emergency department (ED) setting.
