Effects of COVID-19 on short-term outcomes of hip arthroplasty: a multicenter, retrospective, propensity score matched study.

Purpose: The Coronavirus Disease 2019 (COVID-19) pandemic delayed elective procedures such as total joint arthroplasty. As surgical volumes return to prepandemic levels, understanding the implications of COVID-19 becomes imperative. This study explored the effects of COVID-19 on the short-term outcomes of hip arthroplasty.

A portable optical detection system for rapid quantification of two rheumatoid arthritis biomarkers.

Background: Rheumatoid arthritis (RA) is a chronic autoimmune disease that causes joint damage and progressive destruction of adjacent cartilage and bones. Quick and accurate detection of rheumatoid factors (RF) and anti-cyclic citrullinated peptide antibodies (anti-CCP) in serum is effective in diagnosing RA and preventing its progression. However, current methods for detecting these two biomarkers are costly, time-consuming, labor-intensive, and require specialized equipment.

Cellulose-mediated mechanical property tuning in small intestinal submucosal matrix to enhance stem cell osteogenic differentiation.

Natural extracellular matrices (ECM) provide a more accurate simulation of the cellular growth environment, making them excellent substrate materials for in vitro cell culture. The porcine small intestinal submucosa (SIS) is one of the most widely used natural ECM that display superior bioactivity. However, decellularization operations often result in fiber breakage and failure to recover mechanical strength in the SIS.

Quotient Complex (QC)-Based Machine Learning for 2D Hybrid Perovskite Design.

With remarkable stability and exceptional optoelectronic properties, two-dimensional (2D) halide layered perovskites hold immense promise for revolutionizing photovoltaic technology. Effective data representations are key to the success of all learning models. Currently, the lack of comprehensive and accurate material representations has hindered AI-based design and discovery of 2D perovskites, limiting their potential for advanced photovoltaic applications.

Targeting Enterobacter cloacae attenuates osteolysis by reducing ammonium in multiple myeloma.

Multiple myeloma (MM)-induced bone disease affects not only patients' quality of life but also their overall survival. Our previous work demonstrated that the gut microbiome plays a crucial role in MM progression and drug resistance. However, the role of altered gut microbiota in MM bone disease remains unclear.
