Senescence Biomarkers and Trajectories of Frailty and Physical Function After Kidney Transplantation.

Cellular senescence is a biological mechanism of aging and age-related diseases. The aim of this study was to examine whether senescence biomarkers are associated with frailty and physical function trajectories in patients undergoing kidney transplantation (KT). We also discussed the relationship between senescence biomarkers and KT function.

A Multicenter Home-based Prehabilitation Intervention in Kidney Transplant Candidates.

Background: Frailty is a modifiable risk factor for morbidity and mortality among kidney transplant (KT) candidates. We previously demonstrated that an 8-wk center-based exercise intervention is associated with improved frailty parameters in patients with advanced chronic kidney disease. This study aimed to adapt the intervention for home-based delivery and examine its feasibility, safety, and acceptability in a multicenter cohort of KT candidates.

Identifying pragmatic solutions to reduce cigarette smoking prevalence in Indigenous North Americans: A sequential exploratory mixed-methods study protocol.

Background: American Indians and Alaska Natives (AI/AN) have the highest prevalence of cigarette smoking of any race or ethnicity in the United States. Efforts to address smoking prevalence in this population have not historically targeted maintenance of smoking cessation, or behaviors associated with pregnancy. Recent longitudinal cohort studies have identified maintenance of cessation and pregnancy as potential opportunities to address smoking in AI/AN people.

Pathologists Providing Direct Patient Care in Thoracic Transplant: Same Objective, Different Scope.

Context.—: Cardiac and pulmonary allograft recipients represent a unique population, frequently interacting with support groups and exhibiting intense curiosity about their pathology. Like other solid organ transplant patients, they have enduring and frequent interaction with the laboratory for routine allograft surveillance.

Prospective Cohort Study Examining the Ability of Performance-Based and Self-Reported Frailty Measures to Predict 30-Day Rehospitalizations After Kidney Transplantation.

Performance-based measures of frailty are associated with healthcare utilization after kidney transplantation (KT) but require in-person assessment. A promising alternative is self-reported frailty. The goal of this study was to examine the ability of performance-based and self-reported frailty measures to predict 30-day rehospitalizations after KT.

The role of the purposeful shared decision making model in vascularized composite allotransplantation.

For some patients who have lost the lower part of an arm, hand transplant offers the possibility of receiving a new limb with varying degrees of sensation and function. This procedure, Vascularized Composite Allotransplantation (VCA), is demanding for patients and their care community and comes with significant risks. As a high-stakes decision, patients interested in VCA are subject to extensive clinical evaluation and eligibility decision making.

Custom silicone Y-stents for the management of anastomotic stenosis in lung transplant recipients.

Background: Airway stenting may be needed to manage anastomotic complications in lung transplant recipients. Conventional stenting strategies may be inadequate due to anatomic variations between the recipient and donor or involvement of both the anastomosis and lobar bronchi.

Methods: We investigated the efficacy of 3D-designed patient-specific silicone Y-stents in managing this scenario.

Increased Pretransplant Inflammatory Biomarkers Predict Death With Function After Kidney Transplantation.

Background: Chronic systemic inflammation is associated with mortality in patients with chronic kidney disease, cardiovascular disease, and diabetes. The goal of this study was to examine the relationship between pretransplant inflammatory biomarkers (growth differentiation factor-15 [GDF-15], interleukin-6 [IL-6], soluble tumor necrosis factor receptor-1, monokine induced by gamma interferon/chemokine [C-X-C motif] ligand 9 [MIG/CXCL9], monocyte chemoattractant protein-1, soluble FAS, tumor necrosis factor-α, interleukin-15, and interleukin-1β) and death with function (DWF) after kidney transplantation (KT).

Methods: We retrospectively measured inflammatory biomarker levels in serum collected up to 1 y before KT (time from blood draw to KT was 130 ± 110 d) in recipients transplanted between January 2006 and December 2018.

Cancer Surveillance in Solid Organ Transplant Recipients With a Pretransplant History of Malignancy: Multidisciplinary Collaborative Expert Opinion.

With improved medical treatments, the prognosis for many malignancies has improved, and more patients are presenting for transplant evaluation with a history of treated cancer. Solid organ transplant (SOT) recipients with a prior malignancy are at higher risk of posttransplant recurrence or de novo malignancy, and they may require a cancer surveillance program that is individualized to their specific needs. There is a dearth of literature on optimal surveillance strategies specific to SOT recipients.

Hidden curricula in academic medicine: Streamlining success for early career scholars from majority and diverse backgrounds.

The hidden curriculum (HC), or implicit norms and values within a field or institution, affects faculty at all career stages. This study surveyed affiliates of a junior faculty training program ( = 12) to assess the importance of HC topics for junior faculty, mentors, and institutional leaders. For non-diverse junior faculty and their mentors, work-life balance, research logistics, and resilience were key HC topics.

Disparities in Influenza, Pneumococcal, COVID-19 Vaccine Coverage in High-Risk Adults Aged 19 to 64 Years in Southeastern Minnesota, 2010-2021.

Background: Despite effective vaccines against influenza, pneumococcus, and COVID-19, uptake has been suboptimal.

Research Question: Although disparities in vaccination by race and ethnicity have been observed, what is the role of other sociodemographic factors in US vaccine uptake?

Study Design And Methods: We conducted a population-based study using the Rochester Epidemiology Project (REP), a comprehensive medical records linkage system, to assess effects of sociodemographic factors including race, ethnicity, individual-level socioeconomic status (SES) via the housing-based socioeconomic status index, education, population density (urban or nonurban), and marital status with uptake of influenza, pneumococcal, and COVID-19 vaccination in high-risk adults. Adults at high risk of invasive pneumococcal disease residing in four counties in southeastern Minnesota who were aged 19 to 64 years were identified.

Risk Factors for Early Fungal Disease in Solid Organ Transplant Recipients: A Systematic Review and Meta-analysis.

Background: Invasive fungal infections are associated with high morbidity in solid organ transplant recipients. Risk factor modification may help with preventative efforts. The objective of this study was to identify risk factors for the development of fungal infections within the first year following solid organ transplant.

Examining the safety and effectiveness of a 4-week supervised exercise intervention in the treatment of frailty in patients with chronic kidney disease.

Background: The optimal duration of antifrailty interventions and how best to deliver them to patients with chronic kidney disease (CKD) is unknown. The aim of this study was to examine the safety, feasibility and preliminary efficacy of a 4-week supervised exercise intervention on frailty in patients with CKD.

Methods: We conducted a prospective feasibility study involving patients with ≥stage 3 CKD (1 patient with stage 3 CKD, 7 patients with stage 4 CKD and 17 patients with stage 5 CKD) who were either frail or prefrail according to the physical frailty phenotype and/or had a Short Physical Performance Battery (SPPB) score ≤10.

Cellular Senescence and Frailty in Transplantation.

Purpose Of Review: To summarizes the literature on cellular senescence and frailty in solid-organ transplantation and highlight the emerging role of senotherapeutics as a treatment for cellular senescence.

Recent Findings: Solid-organ transplant patients are aging. Many factors contribute to aging acceleration in this population, including cellular senescence.

A Single-Center Retrospective Evaluation of Decision-Making and Factors Motivating Hand Transplant Candidates.

Introduction: Advancements in vascularized composite allotransplantation have made hand transplants possible for persons living with upper limb loss. Hand transplantation is not a life-saving procedure, but rather a quality-of-life enhancing procedure; hence the risk of morbidity and mortality must be weighed against improvements in function and appearance. This study explored the decision-making process of patients evaluated for hand transplantation.

Expanded extracorporeal membrane oxygenation bridge to heart and lung transplant candidate selection does not impact outcomes compared to traditional candidate selection criteria.

Extracorporeal membrane oxygenation is used as a bridge to transplant (ECMO-BTT) in selected patients. The objective of this study was to determine whether 1-year post-transplant and post-ECMO survival are impacted by traditional compared to expanded selection criteria. We performed a retrospective study of patients >17 years who received ECMO as bridge to transplant (BTT) or bridge to transplant decision for lung or combined heart and lung transplantation at the Mayo Clinic Florida and Rochester.

Physiological Age by Artificial Intelligence-Enhanced Electrocardiograms as a Novel Risk Factor of Mortality in Kidney Transplant Candidates.

Background: Mortality risk assessment before kidney transplantation (KT) is imperfect. An emerging risk factor for death in nontransplant populations is physiological age as determined by the application of artificial intelligence to the electrocardiogram (ECG). The aim of this study was to examine the relationship between ECG age and KT waitlist mortality.

Disparities in vaccination rates in solid organ transplant patients.

Introduction: Vaccinations against preventable respiratory infections such as Streptococcus pneumoniae and influenza are important in immunosuppressed solid organ transplant (SOT) recipients. Little is known about the role of age, race, ethnicity, sex, and sociodemographic factors including rurality, or socioeconomic status (SES) associated with vaccine uptake in this population.

Methods: We conducted a population-based study using the Rochester Epidemiology Project, a medical records linkage system, to assess socioeconomic and demographic factors associated with influenza and pneumococcal vaccination rates among adult recipients of solid organ transplantation (aged 19-64 years) living in four counties in southeastern Minnesota.

Routine Donor and Recipient Screening for and Species in Lung Transplant Recipients.

Background: , , and may cause post-transplant infections in lung transplant recipients. We evaluated routine pretransplant screening for these Mollicutes.

Methods: We retrospectively reviewed records of lung transplant recipients at our tri-site institution from 01/01/2015 to 11/15/2019.

Smoking Behaviors Among Indigenous Pregnant People Compared to a Matched Regional Cohort.

Introduction: Smoking commercial tobacco products is highly prevalent in American Indian and Alaska Native (Indigenous) pregnancies. This disparity directly contributes to maternal and fetal mortality. Our objective was to describe cigarette smoking prevalence, cessation intervention uptake, and cessation behaviors of pregnant Indigenous people compared to sex and age-matched regional cohort.

Education for patients with limb loss or absence: Aging, overuse concerns, and patient treatment knowledge gaps.

The goals of vascular composite allotransplantation (VCA) for hand are to maximize functional status and psychosocial wellbeing and to improve quality of life. Candidates are carefully vetted by transplant programs through an extensive evaluation process to exclude those patients with contraindications and to select those that are most likely to attain functional or quality of life benefit from transplant. Patient choice for any treatment, however, requires that candidates be able to understand the risks, benefits, and alternatives before choosing to proceed.

Indigenous Smoking Behaviors in Olmsted County, Minnesota: A Longitudinal Population-Based Study.

Objective: To describe smoking behaviors and pharmaceutical cessation aid uptake in a population-based Indigenous cohort compared with an age- and sex-matched non-Indigenous cohort.

Patients And Methods: Using the health record-linkage system of the Rochester Epidemiology Project (January 1, 2006, to December 31, 2019), smoking data of Indigenous residents of Olmsted County in Minnesota were abstracted to define the smoking prevalence, incidence, cessation, relapse after cessation, and pharmaceutical smoking cessation aid uptake compared with a matched non-Indigenous cohort. Prevalence was analyzed with a modified Poisson regression; cessation and relapse were evaluated with generalized estimating equations.

Using team science in vascularized composite allotransplantation to improve team and patient outcomes.

Reconstructive allografts using Vascularized Composite Allotransplantation (VCA) are providing individuals living with upper limb loss and facial disfigurement with new opportunities for a sensate, esthetically acceptable, and functional alternative to current treatment strategies. Important research attention is being paid to how best to assess and screen candidates for VCA, measure optimal patient outcomes, and support patient adherence to lifelong behaviors and medical regimens. Far less attention, however, has been dedicated to the team science required for these complex VCA teams to form, prepare, and provide the highest quality clinical and psychosocial care to those receiving VCA.
