Hybrid Immunity and SARS-CoV-2 Antibodies: Results of the HEROES-RECOVER Prospective Cohort Study.

Background: There are limited data on whether hybrid immunity differs by count and order of immunity-conferring events (infection with severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2] or vaccination against coronavirus disease 2019 [COVID-19]). From a multi-site cohort of frontline workers, we examined the heterogeneity of the effect of hybrid immunity on SARS-CoV-2 antibody levels.

Methods: Exposures included event count and event order, categorized into 7 permutations.

Local Health Department Activities to Reduce Emergency Department Visits for Substance Use Disorders.

The Affordable Care Act (ACA) provides financial incentives to prevent substance use disorders (SUDs). Local health departments (LHDs) can receive funds to establish care teams that partner with primary care providers and health systems. This study estimates the potential effect of LHDs on emergency visits for SUDs, using linked data sets from the Healthcare Cost and Utilization Project Emergency Department (ED) sample for the State of Maryland-2012, the National Association of County and City Health Officials Profiles Survey 2013, and Area Health Resource File 2013 to estimate potential effect of LHDs' provision of SUD preventive care and SUD-related policy implementation.

Variation of preventive service utilization by state Medicaid coverage, cost-sharing, and Medicaid expansion status.

Preventive services can help reduce costs associated with chronic conditions. Medicaid beneficiaries have high rates of chronic conditions, but state Medicaid coverage and cost-sharing of preventive services varies widely. States that chose to expand Medicaid under the ACA were incentivized to cover recommended preventive services at no cost-sharing.

Reducing Preventable Hospitalization and Disparity: Association With Local Health Department Mental Health Promotion Activities.

Introduction: Serving as the center of community-engaged health programs, local health departments can play a critical role in promoting community mental health. The objectives of this study were to explore the association between local health department activities and (1) preventable hospitalizations for individuals with mental disorders, and (2) associated racial disparities in preventable hospitalizations.

Method: Employing the linked data sets of the 2012-2013 Healthcare Cost and Utilization Project state inpatient discharge file of the State of Maryland, the National Association of County and City Health Officials Profiles Survey, the Area Resource File, and U.

A Prospective Study of Depression and Weight Change After Kidney Transplant.

Context: Kidney transplant recipients have great risk for gaining significant weight (upward of 10 kg) in the first year posttransplant. Clinical depression can occur in response to life situations and is associated with weight gain.

Objective: To explore the association between demographic characteristics, weight change, and depression posttransplantation.

Food availability as a determinant of weight gain among renal transplant recipients.

Excessive weight gain is common after renal transplantation, but it is unknown whether environmental factors, such as food availability, contribute to this important clinical problem. We evaluated the effects of food availability (fast food restaurants, convenience stores, and grocery stores within 1, 2, and 3 mile buffers of transplant recipients' residences) on body mass index (BMI) change during the first year post-transplant. Participants (n = 299) resided in Memphis, Tennessee.

Exploring contextual factors and patient activation: evidence from a nationally representative sample of patients with depression.

Patient activation has been considered as a "blockbuster drug of the century." Patients with mental disorders are less activated compared to patients with other chronic diseases. Low activation due to mental disorders can affect the efficiency of treatment of other comorbidities.

Lessons learned: experiences of gaining weight by kidney transplant recipients.

Context: Weight gain after kidney transplantation is a widespread phenomenon, but the question of effective strategies to intervene in patterns that lead to weight gain has not been well studied.

Objective: To obtain (1) insight into recipients' perceptions of weight gain and (2) information on intervention strategies that recipients think could prevent weight gain.

Design: Qualitative focus groups and a 13-question, multiple-choice survey were used.
