Multifaceted Intervention to Improve Graft Outcome Disparities in African American Kidney Transplants (MITIGAAT Study): Protocol for a Randomized Controlled Trial.

Background: The outcome disparities for African American recipients of kidney transplant is a public health issue that has plagued the field of transplant since its inception. Based on national data, African American recipients have nearly twice the risk of graft loss at 5 years after transplant, when compared with White recipients. Evidence demonstrates that medication nonadherence and high tacrolimus variability substantially impact graft outcomes and racial disparities, most notably late (>2 years) after the transplant.

Comparison of At-Home Versus In-Clinic Receipt of Long-Acting Injectable Cabotegravir/Rilpivirine.

Background: The need for frequent travel to a clinic could impair access to injectable antiretroviral therapy for persons living with human immunodeficiency virus type 1 (HIV-1) infection. We hypothesized that allowing persons receiving treatment with long-acting injectable cabotegravir plus rilpivirine (LA CAB/RPV) to receive and store the medication in their own refrigerator prior to in-home administration by a healthcare provider would be as safe and effective as receiving treatment in a clinic.

Methods: Persons prescribed LA CAB/RPV in the Infectious Diseases clinic at the Medical University of South Carolina were offered enrollment in this non-randomized, observational study between August 2021 and December 2022.

Pelvic Organ Prolapse Surgery: Postoperative Quality of Life in Ethiopian Women.

Introduction And Hypothesis: Pelvic organ prolapse (POP) has a profound influence on a woman's quality of life (QoL). Assessment of QoL using patient-reported outcome (PRO) measures in pelvic organ prolapse surgery is common practice in developed countries, but despite the burden of POP in developing countries, such as Ethiopia, the use of PROs to record preoperative and postoperative QoL scores is limited. This study is aimed at assessing the QoL among Ethiopian women with POP before and after surgery using the validated Pelvic Organ Quality of Life (P-QoL) questionnaire.

Objective Measures of Cardiometabolic Risk and Advanced Fibrosis Risk Progression in Primary Care Patients With Metabolic Dysfunction-Associated Steatotic Liver Disease.

Background: We examined the association of objective measures of cardiometabolic risk with progression to a high-risk for advanced fibrosis in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) at initially low- and indeterminate-risk for advanced fibrosis.

Methods: We performed a retrospective cohort study of primary care patients with MASLD between 2012 and 2021. We evaluated patients with MASLD and low- or indeterminate-risk Fibrosis-4 Index (FIB-4) scores and followed them until the outcome of a high-risk FIB-4 (≥2.

Statin prescriptions and progression of advanced fibrosis risk in primary care patients with MASLD.

Objective: We aimed to determine the association of statins with progression to a high risk for advanced fibrosis in primary care patients with metabolic dysfunction-associated steatotic liver disease (MASLD).

Design: This retrospective cohort study of electronic health record data included patients with MASLD and an initial low or indeterminate risk for advanced fibrosis, determined by Fibrosis-4 Index (FIB-4) score (<2.67).

Neonatal mortality during the war in Tigray: a cross-sectional community-based study.

Background: Neonatal mortality is among the key national and international indicators of health services. The global Sustainable Development Goal target for neonatal mortality is fewer than 12 deaths per 1000 livebirths, by 2030. Neonatal mortality estimates in the 2019 Ethiopian Demographic Health Survey found 25·7 deaths per 1000 livebirths.

Setting: Administrative claims data.

FIB-4 as a Time-varying Covariate and Its Association With Severe Liver Disease in Primary Care: A Time-dependent Cox Regression Analysis.

Background And Goals: The Fibrosis-4 Index (FIB-4) has demonstrated a strong association with severe liver disease (SLD) outcomes in primary care, but previous studies have only evaluated this relationship using 1 or 2 FIB-4 scores. In this study, we determined the association of FIB-4 as a time-varying covariate with SLD risk using time-dependent Cox regression models.

Study: This retrospective cohort study included primary care patients with at least 2 FIB-4 scores between 2012 and 2021.

Medication Safety Events After Acute Myocardial Infarction Among Veterans Treated at VA Versus Non-VA Hospitals.

Introduction: Fragmentation of health care across systems can contribute to mistakes in prescribing and filling medications among patients treated for myocardial infarction (MI). We sought to compare omissions, duplications, and delays in outpatient medications used for secondary prevention among veterans treated for MI at Veterans Affairs (VA) versus non-VA hospitals.

Methods: We utilized national VA and Centers for Medicare and Medicaid Services data (2012-2018) to identify veterans 65 years or older hospitalized for MI and measured the use of outpatient medications for secondary prevention in the 30 days after MI among those treated at VA versus non-VA hospitals.

Toward precision medicine using a "digital twin" approach: modeling the onset of disease-specific brain atrophy in individuals with multiple sclerosis.

Digital Twin (DT) is a novel concept that may bring a paradigm shift for precision medicine. In this study we demonstrate a DT application for estimating the age of onset of disease-specific brain atrophy in individuals with multiple sclerosis (MS) using brain MRI. We first augmented longitudinal data from a well-fitted spline model derived from a large cross-sectional normal aging data.

Impact of a double catastrophe, war and COVID-19, on health service utilization of a tertiary care hospital in Tigray: an interrupted time-series study.

Background: In developing nations with fragile healthcare systems, the effect of war is likely to be much worse than it would be in more developed countries. The presence of COVID-19 will also likely exacerbate the war's impact. This study set out to determine the effect of armed conflict and the COVID-19 pandemic on health service utilization at Ayder Comprehensive Specialized Hospital, in the Tigray region of Ethiopia.

Results of a multicenter cluster-randomized controlled clinical trial testing the effectiveness of a bioinformatics-enabled pharmacist intervention in transplant recipients.

An ambulatory medication safety dashboard was developed to identify missing labs, concerning labs, drug interactions, nonadherence, and transitions in care. This system was tested in a 2-year, prospective, cluster-randomized, controlled multicenter study. Pharmacists at 5 intervention sites used the dashboard to address medication safety issues, compared with usual care provided at 5 control sites.

Sulfonylureas as second line therapy for type 2 diabetes among veterans: Results from a National Longitudinal Cohort Study.

Aims: To assess if switching to or adding sulfonylureas increases major adverse cardiovascular events (MACE) or severe hypoglycemia versus remaining on metformin alone.

Materials And Methods: This was a retrospective, longitudinal cohort utilizing United States Veterans Health Administration and Medicare data. Veterans with type 2 diabetes on metformin monotherapy between 2004 and 2006 were identified.

Recurrence risk in symptomatic intracranial stenosis treated medically in the real world.

Background: The risk of early recurrence in medically treated patients with intracranial atherosclerotic stenosis (ICAS) may differ in clinical trials versus real-world settings. Delayed enrollment may contribute to lower event rates in ICAS trials. We aim to determine the 30-day recurrence risk in a real-world setting of symptomatic ICAS.

Prevalence and multi-level factors associated with acute malnutrition among children aged 6-59 months from war affected communities of Tigray, Northern Ethiopia, 2021: a cross-sectional study.

Background: Armed conflicts greatly affect the health, nutrition, and food security of conflict affected settings particularly children. However, no empirical data exist regarding context specific factors contributing towards acute malnutrition in the war-torn Tigray, Ethiopia. Thus, this study aimed to identify individual and community level factors associated with acute malnutrition among children aged 6-59 months from armed conflict affected settings of Tigray, Ethiopia.

Real-World Primary Care Data Comparing ALT and FIB-4 in Predicting Future Severe Liver Disease Outcomes.

Background: Alanine aminotransferase (ALT) has long provided a cue for chronic liver disease (CLD) diagnostic evaluation, but the Fibrosis-4 Index (FIB-4), a serologic score used for predicting advanced fibrosis risk in CLD, may provide an alternative signal.

Objective: Compare the predictive performance of FIB-4 with ALT for severe liver disease (SLD) events while adjusting for potential confounders.

Design: Retrospective cohort study of primary care electronic health record data from 2012 to 2021.

Multilevel Intervention to Improve Racial Equity in Access to Kidney Transplant.

Background: African Americans (AAs) have reduced access to kidney transplant (KTX). Our center undertook a multilevel quality improvement endeavor to address KTX access barriers, focused on vulnerable populations. This program included dialysis center patient/staff education, embedding telehealth services across South Carolina, partnering with community providers to facilitate testing/procedures, and increased use of high-risk donors.

Borderzone infarction and recurrent stroke in intracranial atherosclerosis.

Background: Intracranial stenosis (ICAS) is a common cause of stroke worldwide and patients with symptomatic ICAS exhibit a high rate of recurrence, particularly in the early period after the initial event. In this study, we aimed to study the association between borderzone infarct and recurrent ischemic stroke in patients hospitalized with symptomatic ICAS.

Methods: This is a retrospective single center study that included patients hospitalized with acute ischemic stroke in the setting of intracranial stenosis (50% or more and an acute ischemic stroke in the territory supplied by the stenosed artery) over a 32-month period.
