Randomized Controlled Trial
Modifying Risks in Ventral Hernia Patients With Prehabilitation: A Randomized Controlled Trial.
The aim of this study was to determine whether preoperative nutritional counseling and exercise (prehabilitation) in obese patients with ventral hernia repair (VHR) results in more hernia-free and complication-free patients. ⋯ This trial was registered with clinicaltrials.gov (NCT02365194).

This study aims to evaluate the trends in cancer (CA) admissions and surgeries after the Affordable Care Act (ACA) Medicaid expansion. ⋯ In states that expanded Medicaid coverage under the ACA, the rate of surgeries for colorectal and lung CA increased significantly, while breast CA surgeries decreased less. Parenthetically, these cancers are subject to population screening programs. We conclude that expanding insurance coverage results in enhanced access to cancer surgery.

Multicenter Study
A Phase II Clinical Trial of Molecular Profiled Neoadjuvant Therapy for Localized Pancreatic Ductal Adenocarcinoma.
One facet of precision medicine is the use of tumor molecular profiling to guide chemotherapeutic selection. We conducted the first prospective clinical trial of molecular profiling to guide neoadjuvant therapy in patients with operable pancreatic ductal adenocarcinoma (PDAC). We hypothesized that more effective systemic therapy would prevent disease progression during neoadjuvant therapy and, therefore, allow more patients to undergo surgery. ⋯ We report the first prospective clinical trial that utilized molecular profiling to select neoadjuvant therapy in patients with operable PDAC. Such high resectability rates have not been observed in prior neoadjuvant trials, suggesting that molecular profiling may improve the efficacy of chemotherapy in these patients.

Xenotransplantation using pig organs could end the donor organ shortage for transplantation, but humans have xenoreactive antibodies that cause early graft rejection. Genome editing can eliminate xenoantigens in donor pigs to minimize the impact of these xenoantibodies. Here we determine whether an improved cross-match and chemical immunosuppression could result in prolonged kidney xenograft survival in a pig-to-rhesus preclinical model. ⋯ Reducing xenoantigens in donor pigs and chemical immunosuppression can be used to achieve prolonged renal xenograft survival in a preclinical model, suggesting that if a negative cross-match can be obtained for humans then prolonged survival could be achieved.

Telemedicine in surgery holds promise for improving access and decreasing costs, but its role remains ill-defined. This pilot study was performed to investigate the safety, feasibility, and financial implications of providing postoperative care using an electronic clinic (eClinic) at a university hospital. ⋯ A safe and efficient postoperative telemedicine program can be constructed utilizing a widely available electronic medical record system, which can improve patient satisfaction, optimize throughput, and increase gross charges for the healthcare system.
