Study: Higher fracture risk after total hip replacement when cementless implant used to treat femoral neck fracture

A study by Hospital for Special Surgery (HSS) and other centers found that total hip replacement performed with a cementless prosthesis for a femoral neck fracture led to a higher rate of a second fracture and subsequent revision surgery. The research was presented today at the American Academy of Orthopaedic Surgeons (AAOS) Annual Meeting in Las Vegas. The results were also published online in The Journal of Arthroplasty in October 2022.

New approach to improving clinical trial enrollment and diversity

Before new therapies can reach patients, they must be tested in clinical trials in representative populations to show that they work and are safe. Failure to enroll enough participants in trials can delay the arrival of new therapies in the clinic and inflate their eventual price tags. Failure to recruit diverse patients could diminish the relevance and generalizability of trial findings. For example, a drug that proves effective for White patients might not work as well in people of other races or ethnicities.

Scientists develop new targeted therapeutic strategies to fight liver metastasis

The research group led by Prof. Zeng Zhutian from the Division of Life Sciences and Medicine of the University of Science and Technology of China (USTC) revealed a new mechanism of immune surveillance by liver-resident macrophages called Kupffer cells (KCs) that prevent liver metastasis from occurring. They also developed a new method for in situ targeted expression and remodeling of KCs’ anti-tumor function, which successfully cleared tumors in various animal models with end-stage liver metastasis, thus providing a new approach to developing clinical immunotherapy for metastatic liver cancers.
