Phase 1 Study of Anito-cel, a d-Domain BCMA CAR T Cell for Refractory or Recurrent Myeloma

This phase 1 study investigates the safety and efficacy of anitocabtagene autoleucel (anito-cel), a BCMA-directed CAR T-cell therapy, in patients with relapsed or refractory multiple myeloma who have undergone multiple prior treatments. The results indicate a high response rate (100%) with a significant proportion achieving complete response (79%), while adverse events, particularly cytokine release syndrome and neurotoxicity, were mostly mild. The findings suggest that anito-cel may be a promising treatment option for this challenging patient population.

Orthopaedic Oncology in India and Asia: A Report on Disease Burden, Access, Current Status, and Improving Care Delivery

The authors investigate the challenges and current status of orthopaedic oncology in Asia, particularly focusing on the significant burden of sarcoma and the socioeconomic factors affecting care delivery. They highlight the need for improved training for specialists, government initiatives, and regional collaboration to address disparities in sarcoma treatment. The study emphasizes that insights gained from Asia's experience can inform global strategies for sustainable healthcare in oncology.

Pre-Reduction Position of Posterior Wall Fragment is Associated with Intra-Articular Displacement

The authors aimed to identify the rate and risk factors for posterior wall fragments becoming intra-articular after closed reduction in posterior acetabular fracture-dislocations. Their findings revealed that a significant proportion (47.7%) of fragments positioned medial to the femoral head prior to reduction displaced into the joint, with inferior positioning also contributing to this outcome. This study highlights the importance of recognizing fragment morphology for improved surgical planning and management.

Cerclage for Fracture Reduction is Not Associated with Nonunion in Vancouver B or C Periprosthetic Femur Fractures with Stable Implants: A Multicenter Retrospective Study

The authors aimed to investigate whether the use of circumferential cerclage wiring during lateral locked plating for Vancouver B1 and C periprosthetic femur fractures is linked to nonunion rates. Their multicenter retrospective study found no significant association between cerclage use and nonunion, with similar rates of deep infection and implant revision between groups. Overall, the findings suggest that cerclage can be safely used without increasing the risk of nonunion in these fractures with stable implants.

Diagnostic Performance and Clinical Outcomes of Intraoperative Neuromonitoring in Adolescent Idiopathic Scoliosis: A Comprehensive Analysis of 5,206 Patients

The authors aimed to identify curve-specific risk factors for intraoperative neuromonitoring (IONM) alerts during spinal fusion surgery for adolescent idiopathic scoliosis (AIS) in a cohort of 5,206 patients. They found that IONM alerts occurred in 5% of patients, with a significant association to larger preoperative major Cobb angles and specific Lenke classifications, but noted that alerts did not adversely affect 2-year surgical correction outcomes. Overall, the study highlights the importance of monitoring and understanding risk factors associated with IONM alerts in AIS surgeries.

Spine Surgery Missions in Low-Resource Settings: Practical Considerations and Lessons Learned

The authors investigate the critical factors that contribute to the success of spine surgery missions in low-resource settings, specifically through their experiences in Jamaica. They emphasize the importance of logistical planning, ethical patient selection, and sustainable partnerships with local institutions to enhance the impact of these missions. The paper offers practical recommendations for surgeons and organizations aiming to conduct similar initiatives.

Effect of Screening with Multicancer Early-Detection Test on Late-Stage Cancer Diagnosis

The authors aimed to determine whether screening with a multicancer early-detection test, in addition to usual care, reduces the incidence of late-stage cancers (stage III or IV) compared to usual care alone. In a randomized controlled trial involving over 142,000 participants, they found no significant difference in the incidence rates of stage III or IV cancers between the two groups after three screening rounds. While there was a trend towards a lower incidence of stage IV cancers, the results were not conclusive, indicating the need for further follow-up.

Extra-Articular Malunions and Nonunions of the Scapular Body and Neck: A Comparison of Functional Outcomes Before and After Reconstruction

This study investigates the functional outcomes of patients with extra-articular malunions and nonunions of the scapular body and neck following surgical reconstruction. The authors found significant improvements in range of motion, strength, and disability scores postoperatively, indicating that corrective surgery effectively addresses the complications associated with these fractures. Overall, the results suggest that timely and principled reconstruction can lead to favorable outcomes in patients suffering from these conditions.

Ceftriaxone versus cefazolin plus gentamicin for antibiotic prophylaxis in Gustilo-Anderson type III open lower extremity fractures

The authors aimed to compare the rates of fracture-related infections (FRI) and other outcomes between ceftriaxone and a combination of cefazolin plus gentamicin for antibiotic prophylaxis in Gustilo-Anderson type III open lower extremity fractures. Their retrospective cohort study found no significant differences in FRI or complications between the two antibiotic regimens, while highlighting that the severity of the fracture and time to antibiotic administration were significant factors associated with higher infection risk.

Tenecteplase Before Thrombectomy at 4.5 to 24 Hours for Basilar Artery Occlusion: The ATTENTION LATE Randomized Clinical Trial

The study aimed to determine whether intravenous tenecteplase administered before endovascular thrombectomy (EVT) improves outcomes in patients with moderate to severe basilar artery occlusion presenting 4.5 to 24 hours after stroke onset. The findings revealed no significant difference in functional independence or safety outcomes between the tenecteplase plus EVT group and the EVT alone group, suggesting that the addition of tenecteplase does not enhance recovery in this patient population.
