Uncertainty Profiles and Treatment Preferences for Intraductal Papillary Mucinous Neoplasms.

Introduction: Intraductal papillary mucinous neoplasms (IPMNs) are pancreatic premalignant lesions frequently detected incidentally. Choosing between surgery and surveillance for IPMNs is rooted in uncertainty. We characterized patient preferences in IPMN management, and examined associations with patients' uncertainty profiles (risk perception, risk attitude, and uncertainty tolerance).

Pancreas Transplantation for Type 2 Diabetes: A Systematic Review, Critical Gaps in the Literature, and a Path Forward.

Pancreas transplantation in patients with type 2 diabetes (T2D) remains relatively uncommon compared with pancreas transplantation in patients with type 1 diabetes (T1D); however, several studies have suggested similar outcomes between T2D and T1D, and the practice has become increasingly common. Despite this growing interest in pancreas transplantation in T2D, no study has systematically summarized the data to date. We systematically reviewed the literature on pancreas transplantation in T2D patients including patient and graft survival, glycemic control outcomes, and comparisons with outcomes in T2D kidney transplant alone and T1D pancreas transplant recipients.

Surgical complications after living and deceased donor liver transplant: The NSQIP transplant experience.

This study used the prospective National Surgical Quality Improvement Program (NSQIP) Transplant pilot database to analyze surgical complications after liver transplantation (LT) in LT recipients from 2017to 2019. The primary outcome was surgical complication requiring intervention (Clavien-Dindo grade II or greater) within 90 days of transplant. Of the 1684 deceased donor and 109 living donor LT cases included from 29 centers, 38% of deceased donor liver recipients and 47% of living donor liver recipients experienced a complication.

The Glioma-Network Interface: A Review of the Relationship Between Glioma Molecular Subtype and Intratumoral Function.

Gliomas are a major cause of morbidity. Direct cortical stimulation mapping offers the ability to identify functional areas within the broader neural network both cortically and subcortically. Since the World Health Organization (WHO) 2016 classification categorized gliomas into molecular subgroups with varied molecular signatures and clinical behavior, it is possible that gliomas may demonstrate rates of functional network integration.

International Travel for Liver Transplantation: A Comprehensive Assessment of the Impact on the United States Transplant System.

Background: International travel for transplantation remains a global issue as countries continue to struggle in establishing self-sufficiency. In the United States, the United Network for Organ Sharing (UNOS) requires citizenship classification at time of waitlisting to remain transparent and understand to whom our organs are allocated. This study provides an assessment of patients who travel internationally for liver transplantation and their outcomes using the current citizenship classification used by UNOS.

Mouse models of glioblastoma for the evaluation of novel therapeutic strategies.

Glioblastoma (GBM) is an incurable brain tumor with a median survival of approximately 15 months despite an aggressive standard of care that includes surgery, chemotherapy, and ionizing radiation. Mouse models have advanced our understanding of GBM biology and the development of novel therapeutic strategies for GBM patients. However, model selection is crucial when testing developmental therapeutics, and each mouse model of GBM has unique advantages and disadvantages that can influence the validity and translatability of experimental results.

Patient and general public attitudes towards clinical artificial intelligence: a mixed methods systematic review.

Artificial intelligence (AI) promises to change health care, with some studies showing proof of concept of a provider-level performance in various medical specialties. However, there are many barriers to implementing AI, including patient acceptance and understanding of AI. Patients' attitudes toward AI are not well understood.

Utility of a Simplified Iliac Artery Calcium Scoring System to Guide Perioperative Management for Renal Transplantation.

Non-contrast computed tomography scans of the abdomen and pelvis (CTAP) are often obtained prior to renal transplant to evaluate the iliac arteries and help guide surgical implantation. The purpose of this study was to describe the association of iliac calcification scores with operative and clinical outcomes using a simplified scoring system. A retrospective review of 204 patients who underwent renal transplant from 1/2013 to 11/2014 and who had a CTAP within 3 years prior to transplant was performed.

Long-term Lower Extremity and Cardiovascular Complications after Simultaneous Pancreas-Kidney Transplant.

Lower extremity (LE) vascular disease and adverse cardiovascular events (ACEs) cause significant long-term morbidity after simultaneous pancreas-kidney (SPK) transplantation. This study's purpose was to describe the incidence of, and risk factors associated with, LE vascular complications and related ACEs following SPK. All SPKs performed at the authors' institution from 2000 to 2019 were retrospectively analyzed.

Metastatic Donor-derived Malignancies Following Simultaneous Pancreas-kidney Transplant: Three Case Reports and Management Strategies.

Unlabelled: Stopping immunosuppression in a transplant patient with donor-derived malignancy offers the theoretical benefit that reconstitution of the patient's immune system will allow "rejection" of the malignancy, as the malignancy also originates from allogeneic tissue. However, this option exists with the caveat that the patient's allograft(s) will likely be rejected too. In simultaneous pancreas-kidney (SPK) recipients, the normal continued functioning and possible absence of malignancy in either the unaffected kidney or pancreas further complicate this decision.

Retrospective-prospective study of safety and efficacy of sofosbuvir-based direct-acting antivirals in HIV/HCV-coinfected participants with decompensated liver disease pre- or post-liver transplant.

Direct-acting antiviral (DAA) therapy has transformed the management of human immunodeficiency virus (HIV) and hepatitis C (HCV) coinfected patients with advanced liver disease. STOP-Coinfection was a multicenter prospective and retrospective, open-label study using sofosbuvir-based DAA therapy to treat HIV/HCV-coinfected participants pre- or post-liver transplant (LT). Sixty-eight participants with end-stage liver disease (Child-Turcotte-Pugh score ≥7 and Model for End-Stage Liver Disease score 6-29) were enrolled, 26 had hepatocellular carcinoma.

The impact of increasing interbody fusion levels at the fractional curve on lordosis, curve correction, and complications in adult patients with scoliosis.

Objective: Radiculopathy from the fractional curve, usually from L3 to S1, can create severe disability. However, treatment methods of the curve vary. The authors evaluated the effect of adding more levels of interbody fusion during treatment of the fractional curve.

The effect of anterior lumbar interbody fusion staging order on perioperative complications in circumferential lumbar fusions performed within the same hospital admission.

Objective: Anterior lumbar interbody fusion (ALIF) is a powerful technique that provides wide access to the disc space and allows for large lordotic grafts. When used with posterior spinal fusion (PSF), the procedures are often staged within the same hospital admission. There are limited data on the perioperative risk profile of ALIF-first versus PSF-first circumferential fusions performed within the same hospital admission.

A Safe Transitions Pathway for post-craniotomy neurological surgery patients: high-value care that bypasses the intensive care unit.

Objective: High-value medical care is described as care that leads to excellent patient outcomes, high patient satisfaction, and efficient costs. Neurosurgical care in particular can be expensive for the hospital, as substantial costs are accrued during the operation and throughout the postoperative stay. The authors developed a "Safe Transitions Pathway" (STP) model in which select patients went to the postanesthesia care unit (PACU) and then the neuro-transitional care unit (NTCU) rather than being directly admitted to the neurosciences intensive care unit (ICU) following a craniotomy.

The impact of obesity on perioperative complications in patients undergoing anterior lumbar interbody fusion.

Objective: Anterior approaches to the lumbar spine provide wide exposure that facilitates placement of large grafts with high fusion rates. There are limited data on the effects of obesity on perioperative complications.

Methods: Data from consecutive patients undergoing anterior lumbar interbody fusion (ALIF) from 2007 to 2016 at a single academic center were analyzed.

A middle cerebral artery ischemic stroke occurring in a child with a large prolactinoma.

Pituitary adenomas are rare in children, and often present with symptoms of headache, nausea or emesis, visual disturbance, or hormonal hypersecretion. With large tumors, mass effect from the lesion can lead to severe endocrinopathy and compression of intracranial neurovascular structures. In this case report, we describe an unusual presentation of an ischemic stroke in the territory of the right middle cerebral artery resulting from a prolactin-secreting macroadenoma.

Development and Validation of a Nipple-Specific Scale for the BREAST-Q to Assess Patient-Reported Outcomes following Nipple-Sparing Mastectomy.

Background: Nipple-sparing mastectomy and immediate reconstruction has become increasingly popular for prophylactic and therapeutic indications. Patient-reported outcomes instruments such as the BREAST-Q provide important information regarding patient satisfaction and aesthetic and functional outcomes. However, a validated patient-reported outcomes scale specifically addressing nipple-related outcomes following nipple-sparing mastectomy is not currently available.

The effect of an organ procurement experience on preclinical medical student perceptions of transplant surgery.

Transplant surgery is a predominantly male specialty with high burnout rates. There are currently limited data regarding how programs can attract a diverse applicant pool to the field of transplant surgery. This study evaluated the effect of an Organ Procurement Experience elective on preclinical medical students' perceptions of transplant surgery in a prospective, longitudinal study.

Treatment of only the fractional curve for radiculopathy in adult scoliosis: comparison to lower thoracic and upper thoracic fusions.

Objective: Many options exist for the surgical management of adult spinal deformity. Radiculopathy and lumbosacral pain from the fractional curve (FC), typically from L4 to S1, is frequently a reason for scoliosis patients to pursue surgical intervention. The purpose of this study was to evaluate the outcomes of limited fusion of the FC only versus treatment of the entire deformity with long fusions.

Outcomes of Posterior Thoracic Corpectomies for Metastatic Spine Tumors: An Analysis of 90 Patients.

Objective: To retrospectively analyze the outcomes and complications of patients with metastatic thoracic spinal tumors (MTTs) who underwent posterior corpectomies.

Methods: Ninety patients with MTTs who underwent posterior corpectomies were retrospectively analyzed. Characteristics evaluated included number of MTTs per year, location, involved vertebrae numbers, sex, histology, pre- and postoperative American Spinal Injury Association (ASIA) grade, visual analog scale (VAS) pain scores, operative time, blood loss, and length of hospital stay.

Circulating Tumor Cells in Breast Cancer Patients Treated by Neoadjuvant Chemotherapy: A Meta-analysis.

Background: We conducted a meta-analysis in nonmetastatic breast cancer patients treated by neoadjuvant chemotherapy (NCT) to assess the clinical validity of circulating tumor cell (CTC) detection as a prognostic marker.

Methods: We collected individual patient data from 21 studies in which CTC detection by CellSearch was performed in early breast cancer patients treated with NCT. The primary end point was overall survival, analyzed according to CTC detection, using Cox regression models stratified by study.

An Innovative Risk-Reducing Approach to Postmastectomy Radiation Delivery after Autologous Breast Reconstruction.

Introduction: Postmastectomy radiation therapy (PMRT) has known deleterious side effects in immediate autologous breast reconstruction. However, plastic surgeons are rarely involved in PMRT planning. Our institution has adopted a custom bolus approach for all patients receiving PMRT.

Co-expression modules identified from published immune signatures reveal five distinct immune subtypes in breast cancer.

Purpose: There is a growing body of literature demonstrating that immune-related expression signatures predict breast cancer prognosis and chemo-/targeted-therapy responsiveness. However, it is unclear whether these signatures correlate with each other or represent distinct immune-related signals.

Methods: We evaluated 57 published immune-related expression signatures in four public breast cancer datasets totaling 3295 samples.

Negative Genetic Testing Does Not Deter Contralateral Prophylactic Mastectomy in Younger Patients with Greater Family Histories of Breast Cancer.

Background: Increasing rates of contralateral prophylactic mastectomy (CPM) correlate with adoption of total skin-sparing mastectomy (TSSM). We aimed to characterize patients with unilateral breast cancer who underwent TSSM with CPM or without CPM (No CPM).

Methods: We reviewed all patients with unilateral breast cancer who underwent TSSM from 2006 to 2013.
