Racial Variation of Donor-Derived Cell-Free DNA in Kidney Transplant Recipients.

Introduction: There is a need for a noninvasive, affordable, sensitive, and specific biomarker to diagnose early acute rejection, to negate the need for frequent biopsies. Dd-cfDNA is a powerful adjunct yet there is limited data on the ethnic differences in its values. There is anecdotal evidence that dd-cfDNA values at rejection may be higher in Black as compared to non-Black recipients.

Outcomes of Bladder Washout for the Treatment of Recurrent Urinary Tract Infections After Renal Transplantation.

Background Current literature suggests that anywhere from 2.9-27% of renal transplant recipients (RTR) will develop recurrent urinary tract infections (UTIs) (≥2 UTIs over six months or ≥3 UTIs over 12 months). Recurrent UTIs are of particular importance to RTR given its increased risk for allograft fibrosis and overall patient survival.

Environmental Benefits of Electronic Table of Contents of Journals Over Print.

Recent discussion has driven debate on the best format for journals to deliver content to their readers. Traditional dogma necessitated a physical print copy, which was sent to subscribers automatically and came with the benefits of ease of use and familiarity. With the passage of time, electronic tables of contents, with or without the option for a print copy, have been used in lieu to save cost and environmental concerns and to allow content to be consumed in a more convenient, tidier way.

Pancreatic Exocrine Secretion and Weight Gain After Pancreas Transplantation.

Introduction: Weight gain after pancreas transplant is a poorly understood phenomenon thought to be related to increased posttransplant insulin production, immunosuppressive medications, and appetite changes. No study has investigated the effect of increased exocrine secretion posttransplant.

Aims And Hypothesis: We hypothesized that exocrine function, measured by fecal elastase-1 (FE-1), was normal posttransplant and not correlated with weight gain.

Measuring Impact of Simulation-Based Informed Consent Training on Surgical Intern's Long-Term Confidence.

Objective: Our objective was to evaluate the outcome of a training program on long-term confidence of interns and attending physicians.

Design: In this prospective cohort study, general surgery interns underwent a training program on informed consent that involved didactics, standardized patient encounters, and supplemental procedure specific guides at the start of the academic year. At the end of the academic year, we surveyed interns from the classes of 2020 (trained) and 2019 (untrained) about their experience and confidence in obtaining an informed consent.

Effects of race and test preparation resources on standardized test scores, a pilot study.

Background: Little research exists on the relationship between pre-examination resources, race, and standardized test outcomes. This study aimed to determine the effect of test preparation resources and race on test scores.

Methods: We surveyed medical students at an allopathic institution on the use of test preparation materials and their test scores.

End-to-end anastomosis as a superior repair type to prevent recurrence of arteriovenous fistula aneurysms and improve patency outcomes.

Background: Arteriovenous fistulae (AVF) complicated by aneurysms are repaired through several mechanisms. Little is known about risk factors for aneurysm recurrence or the efficacy of subsequent repair of recurring aneurysms.

Methods: About 291 patients underwent AVF aneurysm repair between 2009 and 2019 at a large urban medical center.

Graft repair of arteriovenous fistula aneurysms is associated with decreased long-term patency.

Introduction: Arteriovenous fistula (AVF) aneurysms are a chronic complication which can be disfiguring, painful, and can rupture. Here, we compare the outcomes between three different methods of AVF aneurysm repair.

Methods: One-way ANOVA, Chi-square, and Fisher Exact analyses were used to compare demographics.

Early Experience Using Donor-derived Cell-free DNA for Surveillance of Rejection Following Simultaneous Pancreas and Kidney Transplantation.

Background: Allograft biopsy is the gold standard for diagnosing graft rejection following simultaneous pancreas and kidney (SPK) transplant. Intraperitoneal biopsies are technically challenging and can be burdensome to patients and the healthcare system. Donor-derived cell-free DNA (dd-cfDNA) is well-studied in kidney transplant recipients; however, it has not yet been studied in the SPK population.

Can Donor-Derived Cell-Free DNA Detect Graft-Versus-Host Disease in Solid Organ Transplantation: A Case Report.

Graft-versus-host disease (GVHD) is a rare complication after solid organ transplant. We present a case of GVHD after simultaneous pancreas kidney transplant. The patient was diagnosed with a cutaneous biopsy after developing the classic symptoms of maculopapular rash, diarrhea, and pancytopenia.

Outcomes following port-a-catheter placement in the Medicare population.

Background: We aimed to evaluate the long-term complication profile associated with port-a-catheter placement.

Methods: Patients undergoing port-a-catheter placement from 2007 to 2012 with 5-year follow up were identified. Descriptive statistics, tests, and multivariate regression models were analyzed.

Outcomes following percutaneous endoscopic gastrostomy versus fluoroscopic procedures in the Medicare population.

Background: In the United States, few high-quality manuscripts have directly compared the complication profiles of percutaneous endoscopic versus fluoroscopic gastrostomy. Thus, it is our goal to compare these 2 common procedures to better understand their efficacy and complication profiles.

Materials And Methods: A retrospective analysis of patient records from Medicare parts A/B from 2007 to 2012 was used to identify percutaneous fluoroscopic gastrostomy and percutaneous endoscopic gastrostomy procedures.

Postoperative Mortality in Patients With Cirrhosis: Reconsidering Expectations.

Background: A diagnosis of cirrhosis increases a patient's risk of postoperative mortality. Surgeons are reticent to operate when cirrhosis is known unless no option is available. This study aimed to identify the modern perioperative risk in cirrhotic patients undergoing intervention under general anesthesia for non-transplant operations.

Economic evaluation of suture versus clip anastomosis in arteriovenous fistula creation.

Objective: Techniques such as the use of nonpenetrating vascular clips for arteriovenous fistula (AVF) anastomotic creation have been developed in an effort to reduce fistula-related complications. However, the outcomes data for the use of clips have remained equivocal, and the cost evaluations to support their use have been largely theoretical. Therefore, the present study aimed to determine both the clinical and the cost outcomes of AVFs created with nonpenetrating vascular clips compared with the continuous suture technique during a 10-year period at a single institution.

Trends in Antibiotic Duration for Complicated Intra-Abdominal Infections : Adaptation to Current Guidelines.

Introduction: The 2017 surgical infection society (SIS) guidelines recommend 4 days of antibiotic therapy after source control for complicated intra-abdominal infections (cIAIs). Inappropriate exposure to antibiotics has a negative impact on outcomes in individual patients and populations. The goal of this study was to evaluate our institution's practice patterns and adherence to current antibiotic guidelines.

Surgical Management of Bronchobiliary Fistula After Thoracoabdominal Trauma.

Bronchobiliary fistulas are exceedingly rare pathological connections between the biliary and the bronchial systems, which result from hepatobiliary neoplasms, abscesses, or thoracoabdominal trauma. Prompt recognition, diagnosis, and intervention is essential in order to prevent the high morbidity and mortality associated with this disease process. Multiple management strategies have been described in the literature; however, the optimal course has not been well defined.

Should Pre-Transplant Hemoglobin A1c Be Used to Predict Post-Transplant Compliance in End-Stage Renal Disease Patients Undergoing Kidney Transplantation?

BACKGROUND Patient compliance with immunosuppressive therapy after transplant has impacts on both graft and patient outcomes. For diabetic end-stage renal disease (ESRD) patients who are undergoing evaluation for kidney transplantation in our program, hemoglobin A1c (HbA1c) level of >10% is used as a flag that the patient may be at risk for noncompliance and that more comprehensive psychosocial screening is needed prior to transplant. We evaluated the association between pre-transplant HbA1c level and post-transplant compliance, as no study to date has looked at this in the transplant population.

Hepaticojejunostomy for Benign Disease: Long-Term Stricture Rate and Management.

The objective of the study was to determine the long-term stricture rate of hepaticojejunostiomy (HJ) performed for benign disease, to compare stricture rates for transplant patients and nontransplant patients, and to compare the success rates of procedural and surgical treatment options. Hospital charts of 135 consecutive patients undergoing HJ between 1998 and 2016 were analyzed retrospectively. The primary outcome was stricture formation.

The diagnostic and prognostic utility of risk factors defined by the AHA/ACCF on the evaluation of cardiac disease in liver transplantation candidates.

Background: The diagnostic and prognostic utility of risk factors proposed by the 2012 American Heart Association and American College of Cardiology Foundation (AHA/ACCF) Scientific Statement on the cardiac assessment of asymptomatic liver transplantation candidates have not been validated. We investigated whether the sum of risk factors proposed by the AHA/ACCF can identify liver transplant candidates at increased cardiac risk.

Methods: In a retrospective cohort of consecutive liver transplantation recipients, we calculated, for each subject, the pre-transplantation sum of AHA/ACCF risk factors (age > 60 years, prior cardiovascular disease, hypertension, dyslipidemia, diabetes mellitus, smoking, and left ventricular hypertrophy).

Trauma Patients' Attitudes toward Organ Donation at an Urban Level I Trauma Center.

Many health-care workers (HCWs) surveyed at a trauma center believed their patients distrusted the organ allocation system. This study compares urban trauma patients' (TPs) attitudes toward organ donation with attitudes from the 2012 National Survey of Organ Donation Attitudes (NSODA). TPs presenting to the trauma clinic between September 2014 and August 2015 were surveyed.
