Article Abstract
Background: The goal of this study was to identify predictors of prolonged operative time (OT) in patients receiving posterior/transforaminal lumbar interbody fusion (P/TLIF) and examine the relationship between prolonged OT and perioperative outcomes in this population.
Methods: The American College of Surgeons National Surgical Quality Improvement Program database was queried for patients undergoing single-level P/TLIF (Common Procedural Terminology code) between 2012 and 2018. Multivariable linear regression models were constructed to identify factors independently associated with changes in OT and examine the relationship between prolonged OT and perioperative outcomes (overall complications, surgical complications, medical complications, 30-day readmission, 30-day reoperation, and length of stay). All models were adjusted for sociodemographic variables, comorbidities, and procedure-specific variables.
Results: Our cohort included 6260 patients. After adjusting for baseline covariates, age between 19 and 39 years increased OT by 15.14 minutes, male sex increased OT by 12.91 minutes, African American race increased OT by 17.82 minutes, other race increased OT by 18.13 minutes, obesity class III increased OT by 27.80 minutes, and the use of navigation increased OT by 10.83 minutes. Our multivariate logistic regression also found that after 2 hours, each additional hour of OT was associated with an increased risk of any complication (3-3.99 hours, odds ratio [OR], 1.68; 4-4.99 hours, OR, 2.33; and >5 hours, OR, 4.65). Incremental increases in OT were also associated with an increased risk of extended length of stay, readmission, and return to the operating room.
Conclusions: The results of this study highlight several factors associated with prolonged OT and underscore its association with poorer perioperative outcomes. These data can be used to risk stratify patients before single-level P/TLIF.

Background: Limited treatment options exist for infrapopliteal disease in patients with chronic limb-threatening ischemia (CLTI), a condition associated with a high risk of limb loss. Interventional management of diseased infrapopliteal vessels with percutaneous transluminal angioplasty (PTA) is associated with high rates of restenosis and reintervention. In the LIFE-BTK trial, the drug-eluting resorbable scaffold (DRS) demonstrated superior 12-month efficacy compared with PTA in a selected CLTI population with predominantly noncomplex, mildly to moderately calcified lesions.

Unlabelled: Aortic dissection is a life-threatening cardiovascular emergency, particularly Stanford type A, which typically necessitates urgent surgical intervention. Despite advances in surgical techniques and perioperative care, preoperative bleeding and coagulopathy remain significant challenges. Tranexamic acid, an antifibrinolytic agent, is widely used to minimize perioperative bleeding in cardiovascular surgeries; however, its role in the non-surgical, preoperative stabilization of aortic dissection has not been well established.

Background: Inflammatory bowel disease (IBD) is a chronic condition characterized by the need for highly individualized treatment plans, requiring patients to make numerous complex medical decisions. Shared decision-making (SDM) has proven effective in improving treatment outcomes, patient satisfaction, and adherence in IBD management; however, its clinical implementation remains challenging. In China, formal SDM nurse roles have not yet been established.

Background: Paediatric patients who underwent surgery for mitral regurgitation (MR) have a high risk of recurrence or death; however, no prediction tool has been developed to risk-stratify this challenging subpopulation.
Methods: In this multicentre cohort study, paediatric patients undergoing surgery for congenital MR in Shanghai Children's Medical Center in January 1st, 2009-December 31st, 2022 were included for analysis while those had a combination with infective endocarditis, anomalous left coronary artery from the pulmonary artery, rheumatic valvular disease, connective tissue disease, or single ventricle were excluded. A Cox regression model predictive of the primary outcome (a composite of mortality or mitral valve [MV] re-operation) was derived and converted to a point-based risk score.
