US Medical-Legal Partnerships to Address Health-Harming Legal Needs: Closing the Health Injustice Gap.

The medical-legal partnership (MLP) model is emerging across the USA as a powerful tool to address the adverse social conditions underlying health injustice. MLPs embed legal experts into healthcare teams to address health-harming legal needs with civil legal remedies. We conducted a narrative review of peer-reviewed articles published between 2007 and 2022 to characterize the structure and impacts of US MLPs on patients, providers, and healthcare systems.

Inequities in Treatments and Outcomes Among Patients Hospitalized With Hypertrophic Cardiomyopathy in the United States.

Background Hypertrophic cardiomyopathy (HCM) is the most common heritable cardiac disease. In small studies, sociodemographic factors have been associated with disparities in septal reduction therapy, but little is known about the association of sociodemographic factors with HCM treatments and outcomes more broadly. Methods and Results Using the National Inpatient Survey from 2012 to 2018, HCM diagnoses and procedures were identified by ( and ) codes.

Association of high-priority exceptions with waitlist mortality among heart transplant candidates.

Background: The US heart allocation system ranks candidates using six categorical status levels. Transplant programs can request exceptions to increase a candidate's status level if they believe their candidate has the same medical urgency as candidates who meet the standard criteria for that level. We aimed to determine if exception candidates have the same medical urgency as standard candidates.

Impact of the COVID-19 Pandemic on Patients Without COVID-19 With Acute Myocardial Infarction and Heart Failure.

Background Excess mortality from cardiovascular disease during the COVID-19 pandemic has been reported. The mechanism is unclear but may include delay or deferral of care, or differential treatment during hospitalization because of strains on hospital capacity. Methods and Results We used emergency department and inpatient data from a 12-hospital health system to examine changes in volume, patient age and comorbidities, treatment (right- and left-heart catheterization), and outcomes for patients with acute myocardial infarction (AMI) and heart failure (HF) during the COVID-19 pandemic compared with pre-COVID-19 (2018 and 2019), controlling for seasonal variation.

Racial Inequities Across Rural Strata in Acute Stroke Care and In-Hospital Mortality: National Trends Over 6 Years.

Background: There are glaring racial and rural-urban inequities in stroke outcomes. The objective of this study was to determine whether there were recent changes to trends in racial inequities in stroke treatment and in-hospital mortality, and whether racial inequities differed across rural strata.

Methods: Retrospective analysis of Black and White patients >18 years old admitted to US acute care hospitals with a primary discharge diagnosis of stroke (unweighted N=652 836) from the National Inpatient Sample from 2012 to 2017.

Aortic Size and Clinical Care Pathways Before Type A Aortic Dissection.

Patients with aortic enlargement are recommended to undergo serial imaging and clinical follow-up until they reach surgical thresholds. This study aimed to identify aortic diameter and care of patients with aortic imaging before aortic dissection (AD). In a retrospective cohort of AD patients, we evaluated previous imaging results in addition to ordering providers and indications.

Reducing Cardiovascular Maternal Mortality by Extending Medicaid for Postpartum Women.

Maternal mortality has been increasing in the United States over the past 3 decades, while decreasing in all other high-income countries during the same period. Cardiovascular conditions account for over one fourth of maternal deaths, with two thirds of deaths occurring in the postpartum period. There are also significant healthcare disparities that have been identified in women experiencing maternal morbidity and mortality, with Black women at 3 to 4 times the risk of death as their White counterparts and women in rural areas at heightened risk for cardiovascular morbidity and maternal morbidity.

Ferumoxytol-enhanced MR Venography of the Central Veins of the Thorax for the Evaluation of Stenosis and Occlusion in Patients with Renal Impairment.

Purpose: To assess the diagnostic performance of ferumoxytol-enhanced MR venography for the detection of thoracic central vein stenosis or occlusion with conventional venography as the reference standard.

Materials And Methods: In this retrospective study, consecutive patients from May 2012 to December 2018 underwent dedicated ferumoxytol-enhanced MR venography of the thoracic central veins and conventional venography within 6 months for detecting central venous stenosis. The central veins were divided into seven segments for evaluation.

Sociodemographic differences in utilization and outcomes for temporary cardiovascular mechanical support in the setting of cardiogenic shock.

Background: Temporary mechanical circulatory support (MCS) devices are increasingly used in cardiogenic shock, but whether sociodemographic differences by sex, race and/or ethnicity, insurance status, and neighborhood poverty exist in the utilization of these devices is unknown.

Methods: Retrospective cross-sectional study using the National Inpatient Sample for 2012-2017. Logistic regression models were used to examine predictors of use of temporary MCS devices and for in-hospital mortality, clustering by hospital-year.

Percutaneous Gastrojejunostomy Tube Insertion in Patients with Surgical Gastrojejunal Anastomoses: Analysis of Success Rates and Durability.

Patients with a gastrojejunal anastomosis pose challenging anatomy for percutaneous gastrojejunostomy (GJ)-tube placement. A retrospective review of 24 patients (mean age 67.8 years, 13 males) with GJ anastomoses who underwent attempted GJ tube placement revealed infeasible placement in 6 patients (25%) due to an inadequate window for puncture.

Percutaneous gastrojejunostomy tubes: Identification of predictors of retrograde jejunal limb migration into the stomach.

Purpose: To identify whether technically modifiable factors during gastrojejunostomy (GJ) tube insertion are predictive of retrograde jejunal limb migration into the stomach.

Materials And Methods: Retrospective review of our procedural database over a 5-year period revealed 988 successful primary GJ tube insertions. Medical records and imaging were reviewed for cases of retrograde jejunal limb migration.

Evaluation of Intraindividual Contrast Enhancement Variability for Determining the Maximum Achievable Consistency in CT.

The purpose of this study was to quantify temporal variability in vascular and parenchymal enhancement within the same patient and to determine technique-related factors contributing to this variability. We identified 100 patients who underwent four CT scans within 12 months with identical acquisition and contrast injection parameters. Enhancement was recorded in the abdominal aorta, main portal vein, liver parenchyma, and subcutaneous fat.

Sequential CT Findings in Patients With Non-small-cell Lung Cancer Receiving Nivolumab.

Background: Nivolumab is a novel immunotherapy that was recently approved for treatment of advanced non-small-cell lung cancer (NSCLC). Patients treated with checkpoint inhibitors may show variable computed tomography (CT) features on follow-up imaging, and it is unclear how reliable conventional response criteria are to determine patient management and outcomes. We report the spectrum of sequential CT findings in patients with advanced stage lung cancer who received nivolumab in an effort to better inform appropriate imaging strategies.

Suspicious breast calcifications undergoing stereotactic biopsy in women ages 70 and over: Breast cancer incidence by BI-RADS descriptors.

Objectives: To determine the malignancy rate overall and for specific BI-RADS descriptors in women ≥70 years who undergo stereotactic biopsy for calcifications.

Methods: We retrospectively reviewed 14,577 consecutive mammogram reports in 6839 women ≥70 years to collect 231 stereotactic biopsies of calcifications in 215 women. Cases with missing images or histopathology and calcifications associated with masses, distortion, or asymmetries were excluded.

A sign on CT that predicts a hazardous ureteral anomaly.

Introduction: An aberrant course of the distal ureter can pose a risk of ureteral injury during surgery for inguinal hernia repair and other groin operations. In a recent case series of inguinoscrotal hernation of the ureter, we found that each affected ureter was markedly anterior to the psoas muscle at its mid-point on abdominal CT. We hypothesized that this abnormality in the abdominal course of the ureter would predict the potentially hazardous aberrant course of the distal ureter.

Inguinoscrotal herniation of the ureter: Description of five cases.

Introduction: Descent of the ureter into the inguinal canal or scrotum is rare but undoubtedly underreported. Most known cases were recognized at the time of surgery for hernia repair. We encountered five cases recently.

Metabolic disorders with clinical and radiologic features of sporadic Creutzfeldt-Jakob disease.

Two patients with metabolic disorders presented with clinical and radiologic features suggestive of sporadic Creutzfeldt-Jakob disease (sCJD). Case 1 was a 50-year-old man with rapid decline in cognitive, behavioral, and motor function following new-onset seizures. MRI was read as consistent with CJD, and he was referred for a treatment trial, but it was determined that he recently experienced rapid correction of hyponatremia resulting in extrapontine myelinolysis.

Quinacrine treatment trial for sporadic Creutzfeldt-Jakob disease.

Objective: To determine whether oral quinacrine increases survival in sporadic Creutzfeldt-Jakob disease (sCJD).

Methods: This NIH/National Institute on Aging-funded, double-blinded, placebo-controlled, stratified randomization treatment trial was conducted at the University of California, San Francisco from February 2005 through May 2009 (ClinicalTrials.gov, NCT00183092).

Sporadic Jakob-Creutzfeldt disease presenting as primary progressive aphasia.
