Introduction: The maternal mortality crisis in the United States disproportionately affects women who are Black, especially those living in the Gulf South. These disparities result from a confluence of healthcare, policy, and social factors that systematically place Black women at greater risk of maternal morbidities and mortality. This study protocol describes the Southern Center for Maternal Health Equity (SCMHE), a research center funded by the National Institutes of Health in 2023 to reduce preventable causes of maternal morbidity and mortality while improving health equity.

Background: Type 2 diabetes mellitus (T2D) remains a pressing public health concern. Despite advancements in antidiabetic medications, suboptimal medication adherence persists among many individuals with T2D, often due to the high cost of medications. To combat this issue, Blue Cross and Blue Shield of Louisiana (Blue Cross) introduced the $0 Drug Copay (ZDC) program, providing $0 copays for select drugs.

Purpose: This retrospective cohort study describes the characteristics of patients with myasthenia gravis (MG) who developed exacerbations (MG-E) and compares their healthcare utilization (HRU) to patients who did not experience exacerbations (MG-O).

Method: De-identified data from patients who had ≥2 MG-related diagnostic code submissions were extracted from the National Veterans Affairs Health Care Network electronic health records between 1999 and 2022. Descriptive statistics, Kaplan-Meier analysis, and per-patient per-year (PPPY) HRU were used to compare the two patient groups.

This study evaluated comparative overall survival (OS) of United States veterans with unresectable hepatocellular carcinoma (uHCC) receiving first-line (1L) atezolizumab plus bevacizumab vs. sorafenib or lenvatinib, overall and across racial and ethnic groups. In this retrospective study, patients with uHCC who initiated atezolizumab plus bevacizumab (post-2020) or sorafenib or lenvatinib (post-2018) were identified from the Veterans Health Administration National Corporate Data Warehouse (1 January 2017-31 December 2022).

Background: The US Department of Veterans Affairs, Department of Defense (VA/DoD) clinical guidelines recommend extended-release naltrexone (XR-NTX) as a treatment option for moderate-to-severe alcohol use disorder (AUD); however, contemporary real-world outcomes related to this guideline are lacking. This retrospective, observational, descriptive study examined treatment patterns and healthcare resource use (HCRU) among veterans with an AUD diagnosis who initiated XR-NTX.

Methods: Veterans with incident AUD who initiated XR-NTX between 8/2014 and 11/2018 were identified.

Importance: Diabetes increases the risk of Parkinson disease (PD). Sodium-glucose cotransporter 2 (SGLT2) inhibitors, a new glucose-lowering therapeutic class, have shown neuroprotective effects in mechanistic studies. However, the association between SGLT2 inhibitors and PD risk in real-world populations with type 2 diabetes (T2D) remains unclear.

Background: High prevalence of depression or anxiety with opioid use for chronic pain complicates co-management and may influence prescribing behaviors.

Objective: Compare clinical effectiveness of electronic medical record clinical decision support (EMR-CDS) versus additional behavioral health (BH) care management for reducing rates of high-dose opioid prescriptions.

Design: Type 2 effectiveness-implementation hybrid stepped-wedge cluster randomized trial in 35 primary care clinics within a health system in LA, USA.

Aim: To assess the cost-effectiveness of a digital diabetes prevention programme (d-DPP) compared with a diabetes prevention programme (DPP) for preventing type 2 diabetes (T2D) in individuals with prediabetes in the United States.

Methods: A Markov cohort model was constructed, simulating a 10-year period starting at the age of 45 years, with a societal and healthcare sector perspective. The effectiveness of the d-DPP intervention was evaluated using a meta-analysis, with that of the DPP as the comparator.

Variation in availability, format, and standardization of patient attributes across health care organizations impacts patient-matching performance. We report on the changing nature of patient-matching features available from 2010-2020 across diverse care settings. We asked 38 health care provider organizations about their current patient attribute data-collection practices.

Uncontrolled hypertension and low antihypertensive medication adherence remain significant clinical challenges. There is a critical need to detect meaningful change in adherence in clinical settings. The authors determined that a ≥2-point change in the 4-item Krousel-Wood Medication Adherence Scale score represents meaningful change in antihypertensive medication adherence.

Background: This analysis assessed the cost-effectiveness of insulin glargine 300 units/mL (Gla-300) versus insulin glargine 100 units/mL (Gla-100) in insulin-naïve adults with type 2 diabetes (T2D) inadequately controlled with oral antidiabetic drugs (OADs).

Methods: Costs and outcomes for Gla-300 versus Gla-100 from a US healthcare payer perspective were assessed using the BRAVO diabetes model. Baseline clinical data were derived from EDITION-3, a 12-month randomized controlled trial comparing Gla-300 with Gla-100 in insulin-naïve adults with inadequately controlled T2D on OADs.

Aim: The action to control cardiovascular risk in diabetes (ACCORD) trial showed a neutral average treatment effect of intensive blood glucose and blood pressure (BP) controls in preventing major adverse cardiovascular events (MACE) in individuals with type 2 diabetes. Yet, treatment effects across patient subgroups have not been well understood. We aimed to identify patient subgroups that might benefit from intensive glucose or BP controls for preventing MACE.

Real-world studies of pyruvate kinase (PK) deficiency and estimates of mortality are lacking. This retrospective observational study aimed to identify patients with PK deficiency and compare their overall survival (OS) to that of a matched cohort without PK deficiency. Patients with ≥1 diagnosis code related to PK deficiency were selected from the US Veterans Health Administration (VHA) database (01/1995-07/2019); patients with a physician-documented diagnosis were included (PK deficiency cohort; index: date of first diagnosis code related to PK deficiency).

Background: The Deep South of the United States, and Louisiana in particular, bears a greater burden of obesity, diabetes, and heart disease compared with other regions in the United States. Throughout the COVID-19 pandemic, there has been a substantial increase in telehealth visits for diabetes management to protect the safety of patients. Although there have been significant advancements in telehealth and chronic disease management, little is known about patient and provider perspectives on the challenges and benefits of telehealth visits among people living with diabetes and providers who care for patients with diabetes in Louisiana.

Aim: This study compared the 5-year incidence rate of macrovascular and microvascular complications for tirzepatide, semaglutide and insulin glargine in individuals with type 2 diabetes, using the Building, Relating, Assessing, and Validating Outcomes (BRAVO) diabetes simulation model.

Research Design And Methods: This study was a 5-year SURPASS-2 trial extrapolation, with an insulin glargine arm added as an additional comparator. The 1-year treatment effects of tirzepatide (5, 10 or 15 mg), semaglutide (1 mg) and insulin glargine on glycated haemoglobin, systolic blood pressure, low-density lipoprotein and body weights were obtained from the SUSTAIN-4 and SURPASS-2 trials.

Aim: To evaluate the impact of telehealth use during the COVID-19 pandemic on glycaemic control and other clinical outcomes among patients with type 2 diabetes.

Methods: We used electronic health records from the Research Action for Health Network (REACHnet) database for patients with type 2 diabetes who had telehealth visits and those who only received in-person care during the pandemic. A quasi-experimental method of difference-in-difference with propensity-score weighting was implemented to mitigate selection bias and to control for observed factors related to telehealth use.
