Results: Mean follow-up was 9.

Knowing When to Ignore the Numbers: Single-Center Experience Transplanting Deceased Donor Kidneys with Poor Perfusion Parameters.

Background: Hypothermic machine perfusion is frequently used in evaluating marginal kidneys with poor perfusion parameters (PPP) contributing to delays in kidney placement or discard. We examined outcomes in deceased donor kidney transplants with PPP compared with those with optimal perfusion parameters (OPP).

Study Design: We conducted a retrospective single-center cohort study from 2001 to 2021 comparing PPP (n = 91) with OPP (n = 598) deceased donor kidney transplants.

Long-term outcomes of kidney transplantation from deceased donors with terminal acute kidney injury: Single center experience and literature review.

Introduction: Long-term outcomes of kidney transplantation from deceased donors (DDKTs) with terminal acute kidney injury (AKI) are not well defined.

Methods: Single center retrospective review of DDKTs from 1/31/07-12/31/19. AKI kidneys were defined by a doubling of the donor's admission serum creatinine (SCr) level AND a terminal SCr ≥2.

Influence of donor and recipient sex on outcomes following simultaneous pancreas-kidney transplantation in the new millennium: Single-center experience and review of the literature.

Introduction: The influence of sex on outcomes following simultaneous pancreas-kidney transplantation (SPKT) in the modern era is uncertain.

Methods: We retrospectively studied 255 patients undergoing SPKT from 11/2001 to 8/2020. Cases were stratified according to donor (D) sex, recipient (R) sex, 4 D/R sex categories, and D/R sex-matched versus mismatched.

Improved surgical outcomes following simultaneous pancreas-kidney transplantation in the contemporary era.

Background: Complications leading to early technical failure have been the Achilles' heel of simultaneous pancreas-kidney transplantation (SPKT). The study purpose was to analyze longitudinally our experience with early surgical complications following SPKT with an emphasis on changes in practice that improved outcomes in the most recent era.

Study Design: Single center retrospective review of all SPKTs from 11/1/01 to 8/12/20 with enteric drainage.

Simultaneous pancreas-kidney transplantation in Caucasian versus African American patients: Does recipient race influence outcomes?

Unlabelled: The influence of African American (AA) recipient race on outcomes following simultaneous pancreas-kidney transplantation (SPKT) is uncertain.

Methods: From 11/01 to 2/19, we retrospectively studied 158 Caucasian (C) and 57 AA patients (pts) undergoing SPKT.

Results: The AA group had fewer patients on peritoneal dialysis (30% C vs.

The use of marginal kidneys in dual kidney transplantation to expand kidney graft utilization.

Purpose Of Review: The purpose of this review is to chronicle the history of dual kidney transplantation (DKT) and identify opportunities to improve utilization of marginal deceased donor (MDD) kidneys through DKT.

Recent Findings: The practice of DKT from adult MDDs dates back to the mid-1990s, at which time the primary indication was projected insufficient nephron mass from older donors. Multiple subsequent studies of short- and long-term success have been reported focusing on three major aspects: Identifying appropriate selection criteria/scoring systems based on pre- and postdonation factors; refining technical aspects; and analyzing longer-term outcomes.

Dual kidney transplants from adult marginal donors: Review and perspective.

The practice of dual kidney transplantation (DKT) from adult marginal deceased donors (MDDs) dates back to the mid-1990s with initial pioneering experiences reported by the Stanford and Maryland groups, at which time the primary indication was estimated insufficient nephron mass from older donors. Multiple subsequent studies of short and long-term success have been reported focusing on three major aspects of DKT: Identifying appropriate selection criteria and developing scoring systems based on pre- and post-donation factors; refining technical aspects; and analyzing mid-term outcomes. The number of adult DKTs performed in the United States has declined in the past decade and only about 60 are performed annually.

Do pretransplant C-peptide levels predict outcomes following simultaneous pancreas-kidney transplantation? A matched case-control study.

Following simultaneous pancreas-kidney transplantation (SPKT), survival outcomes are reported as equivalent in patients with detectable pretransplant C-peptide levels (Cp+) and a "type 2″ diabetes mellitus (DM) phenotype compared to type 1 (Cp negative [Cp-]) DM. We retrospectively compared 46 Cp+ patients pretransplant (≥2.0 ng/mL, mean 5.

Association Between Serum Testosterone and Serum PSA Among Men With and Without Partial Androgen Deficiency.

Serum prostatic specific antigen (PSA) and serum testosterone levels share an undefined relationship with each other, with many conflicting studies showing both positive and negative correlation between them. Our aim was to assess association between serum PSA and serum testosterone in healthy men with normal testosterone levels and men with partial androgen deficiency (PADAM). A cross sectional study was conducted at a teaching hospital setting where serum testosterone and aging male symptom scale (AMS) scores along with PSA were studied in 255 men (> 50 years) with and without PADAM.

Free radicals: emerging challenge in environmental health research in childhood and neonatal disorders.

Infants and children may undergo severe oxidative stress due to disease state, pre-existing nutritional status, frequent use of oxygen, and lower levels of antioxidant defenses. Antioxidant defenses, made up of intracellular and extra-cellular components, work synergistically to prevent oxidative damage. Total antioxidant activity (TAA) was analyzed by method of ferric reducing antioxidant power assay (FRAP).

Zinc and copper in preterm neonates: relationship with breast milk.

The study was conducted to assess copper and zinc levels in neonate's serum, mother's serum, neonate's hair and urine and to ascertain association between them. It is of concern whether zinc and copper deficiency is present at birth and maternal blood and breast milk zinc and copper levels have any effect on this. The study sample included 155 neonates with gestational age 26-41 wks and birth weight 0.

Anatomic and electrogram approaches have been described for ablation of slow pathway in patients with atrioventricular nodal tachycardia. The purpose of this study was to identify parameters to predict successful slow pathway ablation using the anatomic approach. Local electrograms at successful and unsuccessful sites were compared in 36 patients undergoing slow pathway ablation using anatomic approach.

Comparative study of the efficacy of metoprolol and verapamil in patients with syncope and positive head-up tilt test response.

Head-up tilt testing is a reliable diagnostic tool for patients with recurrent unexplained syncope. It has also been used to assess the drug efficacy for the treatment of patients with syncope. The objective of this study was to assess the efficacy of verapamil compared with metoprolol in a randomized crossover design for patients with syncope and a positive tilt test response.

Atherosclerosis in transplant heart.

Graft atherosclerosis in the transplant heart is essentially asymptomatic due to denervation of the transplant heart and also is rapidly progressive. After one year it is the major cause of transplant rejection. Histopathologically, graft atherosclerosis differs from the conventional atherosclerosis.
