With the rapid increase in the number of implant operations, the incidence of bone infections has increased. Methicillin-resistant Staphylococcus aureus (S. aureus) and other emerging fully drug-resistant strains make the management of bone infections even more challenging. Bone infections are mainly caused by S. aureus and require extensive surgical intervention and long-term antibiotic therapy. The host autophagy response is critical to the elimination of S. aureus infections. In this study, we demonstrate that a circular RNA (circRNA), circSyk, is a potential biological target for the treatment of S. aureus-induced bone infection. Most importantly, S. aureus regulates circSyk to block autophagy and promote bone destruction via the circSyk/miR-5106/Sik3 axis in a nonclassical pathway, which is involved in the S. aureus infection process through a competitive endogenous RNA network. In summary, this study proposes a novel perspective on the immune escape of S. aureus in bone infections, based on circRNA.

Lymphotoxin β receptor (LTβR/TNFRSF3) signaling plays a crucial role in immune defense. Notably, LTβR-deficient (LTβR) mice exhibit severe defects in innate and adaptive immunity against various pathogens and succumb to infection. Here, we investigated the bone marrow (BM) and peritoneal cavity (PerC) compartments of LTβR mice during infection, demonstrating perturbed B-cell and T-cell subpopulations in the absence of LTβR signaling.

Background: Differentiating periprosthetic joint infections (PJI) from aseptic failure is challenging in total joint arthroplasty. To date, there is no consensus about the most accurate criteria to diagnose PJI. The current study compares common diagnostic PJI criteria.

Background: Hemicondylar fresh frozen allografts address partial knee defects while preserving native anatomy and bone stock. This study evaluated long-term survival, failure modes, and functional outcomes following hemicondylar reconstruction.
Methods: We conducted a retrospective analysis of hemicondylar fresh frozen allograft reconstructions.
Background: This study aims to gain further insights into the characteristics of the rare subtype of acute myeloid leukemia (AML) with BCR∷ABL by analyzing laboratory detection results of various gene mutations, such as NPM1.
Methods: Laboratory detection results of multiple gene missense mutations, including NPM1, were analyzed in a case of primary AML with BCR∷ABL.
Results: The patient exhibited morphological features of acute leukemia in the bone marrow.

Objective: Present study aimed to determine the demographic, epidemiological and pathological features of human cystic echinococcosis (CE) cases using patients' hospital based clinical history from 2012-2023.
Methods: The current retrospective study was conducted from June-December and aimed to investigate the incidence of human CE in Pakistan. A total of 74 surgically confirmed patients' data was retrieved from the hospital records.
