Purpose: Scapholunate dissociation (SLD) is a common entity encountered by hand surgeons. While multiple methods for surgical treatment exist, there is little agreement on the best surgical techniques to treat chronic, static SLD. Our study's goal was to assess the long-term (greater than five years), clinical and radiologic outcomes of the currently recommended treatment options for chronic, static SLD.
Methods: We performed a review of the literature to assess outcomes after surgical treatment of chronic, static SLD with long-term follow-up of greater than five years.
Results: We found only six studies that encompassed the modified Brunelli tenodesis, capsulodesis, scapholunate arthrodesis, and bone-ligament-bone graft using the modified Cuenod procedure. All were level of evidence IV. Many patients went back to some form of work. Tenodesis showed less development of arthritis and greater improvement in scapholunate gap, while capsulodesis showed greater postoperative flexion and extension. Of note, study size varied with 67 combined patients in the capsulodesis studies and 30 patients in the tenodesis studies.
Conclusion: There was no clear superiority of one procedure over the others. More long-term data are needed to identify the best surgical treatment of chronic, static SLD.

Background: Cervical cancer disparities persist among minoritized women due to infrequent screening and poor follow-up. Structural and psychosocial barriers to following up with colposcopy are problematic for minoritized women. Evidence-based interventions using patient navigation and tailored telephone counseling, including the Tailored Communication for Cervical Cancer Risk (TC3), have modestly improved colposcopy attendance.

As a commonly employed method for analyzing time-to-event data involving functional predictors, the functional Cox model assumes a linear relationship between the functional principal component (FPC) scores of the functional predictors and the hazard rates. However, in practical scenarios, such as our study on the survival time of kidney transplant recipients, this assumption often fails to hold. To address this limitation, we introduce a class of high-dimensional partially linear functional Cox models, which accommodates the non-linear effects of functional predictors on the response and allows for diverging numbers of scalar predictors and FPCs as the sample size increases.

Optimizing operating room (OR) utilization is critical for enhancing hospital management and operational efficiency. Accurate surgical case duration predictions are essential for achieving this optimization. Our study aimed to refine the accuracy of these predictions beyond traditional estimation methods by developing Random Forest models tailored to specific surgical departments.

Organoid technology provides a transformative approach to understand human physiology and pathology, offering valuable insights for scientific research and therapeutic development. Human gastric organoids, in particular, have gained significant interest for applications in disease modeling, drug discovery, and studies of tissue regeneration and homeostasis. However, the lack of standardized quality control has limited their extensive clinical applications.

Background: Complex surgery during initial cancer treatment can limit surgical options when planning management of a secondary malignancy. Subtotal esophagectomy and pancreatoduodenectomy are the most invasive and difficult procedures in gastroenterological surgery. Surgical cases in which subtotal esophagectomy was performed after pancreatoduodenectomy with pancreaticogastrostomy are extremely rare and challenging procedures due to the resulting complicated anatomical changes.
