Universal Health Insurance does not exist in the United States for two reasons: (1) there is a general unwillingness to dismantle the historically grown framework of the world's most complex mix of public and private sector health coverage and (2) mere cost considerations. The first concern can be abated by establishing a Universal Health Insurance system which retains many or most of the historically grown infrastructure. Cost containment of such a reform is addressed herein in that the two proposed pathways comprise either (1) a leveled solution through Medicare-expansion for the uninsured only or (2) a more complex solution through a national, 2-tier healthcare system for all Americans.

The maximum cumulative life span of kidneys and livers first in donors and then in transplant recipients has not been established. The purpose of this study was to determine if cumulative organ function for more than 90 years is possible for transplanted kidneys and livers. This study included kidney and liver transplants from living or deceased donors ≥55 years.

Article Synopsis
  • The first successful pancreas transplant occurred in December 1966, and the study reviews its evolution over 50 years to evaluate outcomes and factors affecting success.
  • Patient and graft survival rates have progressively improved across six transplant eras, with the half-lives of pancreas grafts being notably longer for combined organ transplants.
  • Key factors leading to better graft survival include first-time transplants, effective exocrine drainage methods, younger donor age, and shorter preservation times.

This commentary article highlights the need for an insurance product for hospital-employed physicians that provides coverage against sham peer review and a complete defense against wrongful hospital allegations of incompetent, whistleblowing, or disruptive behavior.

The Banff pancreas working schema for diagnosis and grading of rejection is widely used for treatment guidance and risk stratification in centers that perform pancreas allograft biopsies. Since the last update, various studies have provided additional insight regarding the application of the schema and enhanced our understanding of additional clinicopathologic entities. This update aims to clarify terminology and lesion description for T cell-mediated and antibody-mediated allograft rejections, in both active and chronic forms.

Objective: To describe the worldwide experience with living donation (LD) in intestinal transplantation (ITx) and compare short-term and long-term outcomes to a propensity-matched cohort of deceased donors.

Background: ITx is a rare life-saving procedure for patients with complicated intestinal failure (IF). Living donation (LD)-ITx has been performed with success, but no direct comparison with deceased donation (DD) has been performed.

Introduction: Dual organ donation and transplantation from living donors (LDs) is a rare practice. Dual organ transplants can be done from the same LD or from different LDs and either simultaneously or sequentially. Simultaneous dual organ transplants from the same LD are of considerable concern due to the magnitude of the donor procedure.

Over the last decades, the number of pancreas transplants has increased all over the world. Since the first pancreas transplant in 1966, patient and graft survival after simultaneous pancreas and kidney as well as after solitary pancreas transplantation have improved significantly. Patient survival at 1 year is >96% in all 3 recipient categories and pancreas graft survival is >90% for simultaneous pancreas and kidney and >86% for solitary transplants.

Article Synopsis
  • - In 1997, a standardized surgical technique for intestinal transplantation from living donors (LD) was established, involving the careful procurement of distal ileum and preservation of important bowel structures to maintain nutrient absorption.
  • - Living donor transplants allow for quicker procedures and can be life-saving for patients with severe, reversible liver conditions caused by long-term total parenteral nutrition (TPN), with successful combined intestinal and liver transplants reported.
  • - Overall, there have been 85 LD intestinal transplants across 12 countries with no major complications or deaths among donors, and outcomes between LD and deceased donor (DD) transplants have been comparable.

Article Synopsis
  • * Both simultaneous pancreas-kidney transplantation (SPK) and pancreas transplant alone enhance long-term survival and significantly improve recipients' quality of life, outweighing potential downsides.
  • * SPK performed before dialysis offers better outcomes than after dialysis, which adversely affects survival rates, suggesting that kidney grafts should be preferentially allocated to SPK candidates.

Background: Drug dosing for Tacrolimus (TAC) and Mycophenolate Mofetil (MMF) after kidney transplantation remains challenging. Therapeutic drug monitoring (TDM) offers a means to individualize drug dosing and improve outcomes.

Methods: In this observational study, patients having mycophenolic acid (MPA) exposure assessed by limited sampling strategy (LSS) within the first 6 months were included and followed for 1 year.

Hospital-acquired conditions (HACs) are used to define hospital performance measures. Patient comorbidity may influence HAC development. The National Inpatient Sample database was used to investigate HACs for the patients who underwent liver transplantation.

Chronic pancreatitis (CP), secondary to a wide variety of etiologies, is a progressive and irreversible disease. Initially, CP is managed with endoscopic interventions, long-term analgesia for its associated chronic abdominal pain syndrome and pancreatic enzyme replacement for exocrine dysfunction. As the disease advances, pancreatic drainage procedures and partial resections are considered, but they leave diseased tissue behind and usually result in short-term relief only.

We describe a unique case of a 53-year-old woman who underwent a nonrelated living donor kidney transplant 9 years after a previous small bowel transplant from her sister. The patient had suffered from short bowel syndrome secondary to volvulus after undergoing bariatric surgery for morbid obesity. Her entire small bowel had to be resected emergently, but she also developed acute kidney failure at the time.

Background: With the advent of minimally invasive techniques, the standard approaches to many surgeries have changed. We compared the financial costs and health care outcomes between standard thymectomy via sternotomy and video assisted thoracoscopic surgery (VATS).

Methods: A 3-year review [2010-2012] of the National Inpatient Sample (NIS) was performed.

Dual kidney transplantation (DKT) is a viable option to increase the donor pool and improve access equity to kidney transplantation. Dual kidneys are procured from carefully selected marginal donors that are not generally acceptable to most transplant centers. This is a narrative review of literature focusing on donor kidney allocation systems and selection of the ideal recipient for DKT.

Background: Transplantation of organs from living donors helps to decrease the organ shortage and shortens waiting times. Living donor (LD) transplantation is also generally associated with better outcomes. Unfortunately, there has been no comprehensive analysis and comparison of all types of solid-organ transplantation from living donors since the inception of the United Network for Organ Sharing (UNOS).

Successful pancreas transplantation is still the only method to restore short-term and long-term insulin independence and good metabolic control for patients with diabetes. Since the first transplant in 1966, tremendous progress in outcome was made; however, transplant numbers have declined since 2004. This article describes the development and risk factors of pancreas transplantation with or without a kidney graft between 2001 and 2016.

Purpose Of Review: The surgical techniques of pancreas transplantation have been evolving and significantly improved over time. This article discusses different current techniques and their modifications.

Recent Finding: At this time, the most commonly used technique is systemic venous drainage (for venous outflow) and enteric drainage (for management of exocrine pancreatic secretions).

Purpose Of Review: Pancreas transplantation remains the best long-term treatment option to achieve euglycemia and freedom from insulin in patients with labile diabetes mellitus. It is an approved procedure for type 1 (T1DM), but it is still considered controversial for type 2 diabetes mellitus (T2DM).

Recent Findings: This study analyzed all primary deceased donor pancreas transplants in patients with T2DM reported to IPTR/UNOS between 1995 and 2015.
