Association of Cardiopulmonary Hemodynamics and Outcomes in Pulmonary Hypertension Following Kidney Transplantation: A Multicenter Retrospective Cohort Study.

Background: Pulmonary hypertension (PH) frequently complicates the evaluation of kidney transplantation (KT) candidates, and is associated with increased adverse outcomes (mortality, delayed graft function [DGF], and major adverse cardiovascular event) following KT.

Research Question: What is the relationship between cardiopulmonary hemodynamics and post-KT outcomes?

Study Design And Methods: We conducted a multicenter retrospective cohort study of adults undergoing KT between October 1, 2011 and October 1, 2021, who underwent right heart catheterization (RHC) to assess cardiopulmonary hemodynamics within 1 year of transplantation. Frailty models and logistic regression models were used to evaluate the association between cardiopulmonary hemodynamics and outcomes (mortality, DGF, major adverse cardiovascular event) following KT.

Intraoperative hypoglycemia among adults with intraoperative glucose measurements: a cross-sectional multicentre retrospective cohort study.

Purpose: Intraoperative hypoglycemia is presumed to be rare, but generalizable multicentre incidence and risk factor data for adult patients are lacking. We used a multicentre registry to characterize adults with intraoperative hypoglycemia and hypothesized that intraoperative insulin administration would be associated with hypoglycemia.

Methods: We conducted a cross-sectional retrospective multicentre cohort study.

AcumenTM hypotension prediction index guidance for prevention and treatment of hypotension in noncardiac surgery: a prospective, single-arm, multicenter trial.

Background: Intraoperative hypotension is common during noncardiac surgery and is associated with postoperative myocardial infarction, acute kidney injury, stroke, and severe infection. The Hypotension Prediction Index software is an algorithm based on arterial waveform analysis that alerts clinicians of the patient's likelihood of experiencing a future hypotensive event, defined as mean arterial pressure < 65 mmHg for at least 1 min.

Methods: Two analyses included (1) a prospective, single-arm trial, with continuous blood pressure measurements from study monitors, compared to a historical comparison cohort.

Feasibility pilot trial for the Trajectories of Recovery after Intravenous propofol versus inhaled VolatilE anesthesia (THRIVE) pragmatic randomised controlled trial.

Introduction: Millions of patients receive general anaesthesia for surgery annually. Crucial gaps in evidence exist regarding which technique, propofol total intravenous anaesthesia (TIVA) or inhaled volatile anaesthesia (INVA), yields superior patient experience, safety and outcomes. The aim of this pilot study is to assess the feasibility of conducting a large comparative effectiveness trial assessing patient experiences and outcomes after receiving propofol TIVA or INVA.

Multicenter evaluation of the Quantra with the QStat Cartridge in adult patients undergoing liver transplantation.

Blood loss and transfusion of blood products are key concerns during liver transplantation. Whole-blood viscoelastic testing devices have been used to monitor hemostatic function and guide the transfusion of blood products in this patient population. The Quantra System with the QStat Cartridge is a new point-of-care, closed-system viscoelastic testing device that measures changes in clot stiffness during coagulation and fibrinolysis using ultrasound detection of resonance.

Successful living donor liver transplantation in a patient with hemophilia A and factor VIII inhibitor: A case report with perioperative recommendations.

Liver transplantation in patients with end-stage liver disease and coexisting hemophilia A has been described. Controversy exists over perioperative management of patients with factor VIII inhibitor predisposing patients to hemorrhage. We describe the case of a 58-year-old man with a history of hemophilia A and factor VIII inhibitor, eradicated with rituximab prior to living donor liver transplantation without recurrence of inhibitor.

Positron emission tomography myocardial perfusion imaging (PET MPI) findings predictive of post-liver transplant major adverse cardiac events.

Positron emission tomography myocardial perfusion imaging (PET MPI) is a noninvasive diagnostic test capable of detecting coronary artery disease, structural heart disease, and myocardial flow reserve (MFR). We aimed to determine the prognostic utility of PET MPI to predict post-liver transplant (LT) major adverse cardiac events (MACE). Among the 215 LT candidates that completed PET MPI between 2015 and 2020, 84 underwent LT and had 4 biomarker variables of clinical interest on pre-LT PET MPI (summed stress and difference scores, resting left ventricular ejection fraction, global MFR).

Intraoperative risk factors of acute kidney injury after liver transplantation.

Acute kidney injury (AKI) is one of the most common complications of liver transplantation (LT). We examined the impact of intraoperative management on risk for AKI following LT. In this retrospective observational study, we linked data from the electronic health record with standardized transplant outcomes.

Association of intraoperative hyperglycemia and postoperative outcomes in patients undergoing non-cardiac surgery: a multicenter retrospective study.

Background: While pre and postoperative hyperglycemia is associated with increased risk of surgical site infection, myocardial infarction, stroke and risk of death, there are no multicenter data regarding the association of intraoperative blood glucose levels and outcomes for the non-cardiac surgical population.

Methods: We conducted a retrospective cohort study from the Michigan Surgical Quality Collaborative, a network of 64 hospitals that prospectively collects validated data on surgical patients for the purpose of quality improvement. We included data for adult general, vascular, endocrine, hepatobiliary, and gastrointestinal operations between 2013 and 2015.

Intraoperative glycemic control in patients undergoing Orthotopic liver transplant: a single center prospective randomized study.

Background: Perioperative hyperglycemia is associated with poor outcomes yet evidence to guide intraoperative goals and treatment modalities during non-cardiac surgery are lacking. End-stage liver disease is associated with altered glucose homeostasis; patients undergoing liver transplantation display huge fluctuations in blood glucose (BG) and represent a population of great interest. Here, we conduct a randomized trial to compare the effects of strict versus conventional glycemic control during orthotopic liver transplant (OLT).

The impact of intraoperative fluid management during laparoscopic donor nephrectomy on donor and recipient outcomes.

Background: Intraoperative fluid management during laparoscopic donor nephrectomy (LDN) may have a significant effect on donor and recipient outcomes. We sought to quantify variability in fluid management and investigate its impact on donor and recipient outcomes.

Methods: A retrospective review of patients who underwent LDN from July 2011 to January 2016 with paired kidney recipients at a single center was performed.

Intraoperative hyperglycemia is independently associated with infectious complications after non-cardiac surgery.

Background: Perioperative hyperglycemia and its associated increase in morbidity and mortality have been well studied in the critical care and cardiac surgery literature. However, there is little data regarding the impact of intraoperative hyperglycemia on post-operative infectious complications in non-cardiac surgery.

Methods: All National Surgery Quality Improvement Program patients undergoing general, vascular, and urological surgery at our tertiary care center were reviewed.

Intra-Abdominal Desmoid Tumour (DT) with Pelvic Extension-A Case Report.

Desmoid Tumour (DT) is a rare benign, myofibroblastic tumour originating from muscle fascia with tendency to recur but, it rarely metastasizes. We are reporting here a case of DT that presented as an intra-abdominal mass with pelvic extension in a patient who underwent hysterectomy for fibroid uterus seventeen years ago. A clinical diagnosis of ovarian malignancy was made.
