Buprenorphine Induction in Trauma Patients With Opioid Use Disorder - A Single Center Experience?

Introduction: Buprenorphine is a Food and Drug Administration-approved therapy for opioid use disorder, with proven efficacy in treatment retention and reduction in opioid use and mortality. Low-dose buprenorphine initiation or microinduction is a novel means of initiation that may allow for an easier transition in patients. Trauma patients have high rates of opioid use disorder and patient directed discharges (PDD).

User Experience of a Just-in-Time Smartphone Resonance Breathing Application for Substance Use Disorder: Acceptability, Appropriateness, and Feasibility.

Background: Addressing the negative impact of substance use disorders (SUDs) on individuals, families, and communities is a public health priority. Most treatments and interventions require engagement with a healthcare provider or someone who can offer recovery support. The need for interventions that facilitate self-management of relapse triggers at the moment they occur is also critical.

Health Disparities in the Neurosurgical Care of Patients with Trigeminal Neuralgia.

Background: There has been limited investigation into how social determinants of health impact treatment outcomes in patients with trigeminal neuralgia (TN). We aimed to investigate how social determinants of health may alter the course of clinical care for patients with TN.

Methods: The electronic medical record was queried for patients with a diagnosis of TN comanaged by neurosurgeons and other facial pain specialists at our medical center.

"Nothing is ever going to change if we don't start advocating for our child.": Community-level disclosure and stigma management strategies among parents of internationally adopted children living with PHIV.

Background: The number of internationally adopted children living with perinatally-acquired HIV (IACP) in the U.S. is increasing, yet little is known about their families' experiences navigating HIV disclosure within a community context.

GM1-gangliosidosis: The caregivers' assessments of symptom impact and most important symptoms to treat.

GM1-gangliosidosis (GM1) is a rare neurodegenerative disorder leading to early mortality and causing progressive decline of physical skills and cerebral functioning. No approved treatment for GM1 exists. In this study-the first to explore priorities of parents of subjects with pediatric onset forms of GM1-we address a crucial gap by characterizing symptoms most critical to caregivers of children with GM1 to treat.

A qualitative exploration of unintentional versus intentional exposure to fentanyl among people who use drugs in Austin, TX.

Background: The prevalence of deaths involving synthetic opioids has historically been lower in Texas than most U.S. states but more than quadrupled from January 2020 to January 2022.

Outcomes of COVID-19 in hospitalized solid organ transplant recipients compared to a matched cohort of non-transplant patients at a national healthcare system in the United States.

Data describing outcomes of solid organ transplant (SOT) recipients with coronavirus disease 2019 (COVID-19) are variable, and the association between SOT status and mortality remains unclear. In this study, we compare clinical outcomes of SOT recipients hospitalized with COVID-19 between March 10, and September 1, 2020, to a matched cohort of non-SOT recipients at a national healthcare system in the United States (US). From a population of 43 461 hospitalized COVID-19-positive patients, we created a coarsened exact matched cohort of 4035 patients including 128 SOT recipients and 3907 weighted matched non-SOT controls.

Reduction of AMPA receptor activity on mature oligodendrocytes attenuates loss of myelinated axons in autoimmune neuroinflammation.

Glutamate dysregulation occurs in multiple sclerosis (MS), but whether excitotoxic mechanisms in mature oligodendrocytes contribute to demyelination and axonal injury is unexplored. Although current treatments modulate the immune system, long-term disability ensues, highlighting the need for neuroprotection. Glutamate is elevated before T2-visible white matter lesions appear in MS.

Prevalence of frailty among kidney transplant candidates and recipients in the United States: Estimates from a National Registry and Multicenter Cohort Study.

Frailty, a measure of physiologic reserve, is associated with poor outcomes and mortality among kidney transplant (KT) candidates and recipients. There are no national estimates of frailty in this population, which may help patient counseling and resource allocation at transplant centers. We studied 4616 KT candidates and 1763 recipients in our multicenter prospective cohort of frailty from 2008-2018 with Fried frailty measurements.

Frailty and Access to Kidney Transplantation.

Background And Objectives: Frailty, a syndrome distinct from comorbidity and disability, is clinically manifested as a decreased resistance to stressors and is present in up to 35% of patient with ESKD. It is associated with falls, hospitalizations, poor cognitive function, and mortality. Also, frailty is associated with poor outcomes after kidney transplant, including delirium and mortality.

The Impact of the mKidney mHealth System on Live Donor Follow-Up Compliance: Protocol for a Randomized Controlled Trial.

Background: Every year, more than 5500 healthy people in the United States donate a kidney for the medical benefit of another person. The Organ Procurement and Transplantation Network (OPTN) requires transplant hospitals to monitor living kidney donors (LKDs) for 2 years postdonation. However, the majority (115/202, 57%) of transplant hospitals in the United States continue to fail to meet nationally mandated requirements for LKD follow-up.

Effect of match-run frequencies on the number of transplants and waiting times in kidney exchange.

Numerous kidney exchange (kidney paired donation [KPD]) registries in the United States have gradually shifted to high-frequency match-runs, raising the question of whether this harms the number of transplants. We conducted simulations using clinical data from 2 KPD registries-the Alliance for Paired Donation, which runs multihospital exchanges, and Methodist San Antonio, which runs single-center exchanges-to study how the frequency of match-runs impacts the number of transplants and the average waiting times. We simulate the options facing each of the 2 registries by repeated resampling from their historical pools of patient-donor pairs and nondirected donors, with arrival and departure rates corresponding to the historical data.

Early Changes in Kidney Distribution under the New Allocation System.

The Kidney Allocation System (KAS), a major change to deceased donor kidney allocation, was implemented in December 2014. Goals of KAS included directing the highest-quality organs to younger/healthier recipients and increasing access to deceased donor kidney transplantation (DDKT) for highly sensitized patients and racial/ethnic minorities. Using national registry data, we compared kidney distribution, DDKT rates for waitlist registrants, and recipient characteristics between January 1, 2013, and December 3, 2014 (pre-KAS) with those between December 4, 2014, and August 31, 2015 (post-KAS).

Center-level utilization of kidney paired donation.

With many multicenter consortia and a United Network for Organ Sharing program, participation in kidney paired donation (KPD) has become mainstream in the United States and should be feasible for any center that performs live donor kidney transplantation (LDKT). Lack of participation in KPD may significantly disadvantage patients with incompatible donors. To explore utilization of this modality, we analyzed adjusted center-specific KPD rates based on casemix of adult LDKT-eligible patients at 207 centers between 2006 and 2011 using SRTR data.

Histocompatibility considerations for kidney paired donor exchange programs.

Purpose Of Review: To highlight the role of histocompatibility testing in kidney paired donor (KPD) exchange programs as well as the new technological advances that may have an effect on KPD.

Recent Findings: Technological advances in human leukocyte antigen (HLA) antibody identification using the Luminex single-antigen bead multiplexing platform have facilitated virtual cross-matching and the ability to accurately match donor/recipient pairs through KPD. A knowledge of the limitations of this assay is the key to proper interpretation of the data and maximization of this new technology.

Single-center kidney paired donation: the Methodist San Antonio experience.

Many potential kidney transplant recipients are unable to receive a live donor transplant due to crossmatch or blood type incompatibility. Kidney paired donation increases access to live donor transplantation but has been significantly underutilized. We established a kidney paired donation program including consented incompatible donor/recipient pairs as well as compatible pairs with older non-human leukocyte antigen identical donors.

Antibody-mediated rejection--an ounce of prevention is worth a pound of cure.

The presence of preformed, donor-specific alloantibodies inpatients undergoing renal transplantation is associated with a high risk of hyperacute and acute antibody-mediated rejection (ABMR), and often limits potential recipients' access to organs from living and deceased donors. Over the last decade, understanding of ABMR has improved markedly and given rise to numerous, diverse strategies for the transplantation of allosensitized recipients. Antibody desensitization programs have been developed to allow renal transplant recipients with a willing but antibody-incompatible living donor to undergo successful transplantation, whereas kidney paired exchange schemes circumvent the antibody incompatibility altogether by finding suitable pairs to donors and recipients.

An international survey of the diagnosis, management, and treatment of hepatitis C in patients with end-stage renal disease.

Objectives: Hepatitis C is one of the leading causes of death from liver disease in the United States, and is frequently associated with renal disease. Two major organizations-the American Association for the Study of Liver Disease and the National Kidney Foundation-have published recommendations regarding the treatment of hepatitis C in the presence of chronic kidney disease; however, these guidelines do not always provide the same recommendations. Given the paucity of data on adherence to the current guidelines, a survey was conducted to provide information about the current practices of physicians in comparison to the published guidelines.

Kidney paired donation: a single center approach to increase living donor transplantation.

Methodist Specialty and Transplant Hospital has performed a total of 125 KPD transplants from the onset of the program in Dec. 2007. With the addition of the KPD program, live donor transplants have increased annually by 35% demonstrating the ability to substantially increase access to transplantation utilizing this modality.

A virtual crossmatch protocol significantly increases access of highly sensitized patients to deceased donor kidney transplantation.

Background: Patients with preexisting antihuman leukocyte antigen (HLA) antibodies (sensitized patients) are more likely to have a positive crossmatch with possible donors and have a lower likelihood of receiving a renal transplant with longer wait times. A virtual crossmatch protocol using solid-phase technology to determine the specificity of anti-HLA antibodies may improve the probability of identifying a crossmatch-negative compatible donor and increase access of sensitized patients to kidney transplantation.

Methods: A virtual crossmatch protocol was implemented on October 1, 2006 with solid-phase HLA antibody characterization for all sensitized patients on the waiting list.

Campath induction for kidney transplantation: report of 297 cases.

Objective: To evaluate 297 adult renal transplantation patients who received Campath-1H-based induction protocol.

Methods: Single center Institutional Review Board approved retrospective chart review of 297 patients who received alemtuzumab induction between November 2003 and December 2005. Maintenance immunosuppression consisted of tacrolimus, mycophenolate mofetil, and rapidly tapered solumedrol with few exceptional cases.

Control of memory CD4 T cell recall by the CD28/B7 costimulatory pathway.

The CD28/B7 costimulatory pathway is generally considered dispensable for memory T cell responses, largely based on in vitro studies demonstrating memory T cell activation in the absence of CD28 engagement by B7 ligands. However, the susceptibility of memory CD4 T cells, including central (CD62L(high)) and effector memory (T(EM); CD62L(low)) subsets, to inhibition of CD28-derived costimulation has not been closely examined. In this study, we demonstrate that inhibition of CD28/B7 costimulation with the B7-binding fusion molecule CTLA4Ig has profound and specific effects on secondary responses mediated by memory CD4 T cells generated by priming with Ag or infection with influenza virus.
