The FLOW program was designed to facilitate appropriate and safe transitions of patients from specialty mental health (SMH) to primary care (PC) as a method of improving access and reducing appointment burden on veterans who have improved or remitted. In this study, the team evaluated the implementation of FLOW across nine Veterans Affairs (VA) sites using a mixed-methods evaluation in a cluster-randomized stepped wedge trial design. Outcome assessments used data from VA databases, dashboards, and semi-structured interviews and were guided by the Reach, Adoption, Effectiveness, Implementation, and Maintenance (RE-AIM) framework.

Introduction: Excess rates of Gulf War illness (GWI) and irritable bowel syndrome (IBS), two chronic multisymptom illnesses, have long been documented among nearly 700,000 veterans who served in the 1990-1991 Persian Gulf War. We sought to report the prevalence, characteristics, and association of GWI and IBS decades after the war in a clinical cohort of deployed Gulf War veterans (GWVs) who were evaluated at the Department of Veterans Affairs' War Related Illness and Injury Study Center (WRIISC) for unexplained chronic symptoms.

Materials And Methods: We analyzed data gathered from clinical intake questionnaires of deployed GWVs who were evaluated at WRIISC clinics between 2008 and 2020.

Introduction: Indeterminate liver nodules (ILNs) are frequently encountered on diagnostic imaging after positive hepatocellular carcinoma (HCC) surveillance results, but their natural history remains unclear.

Methods: We conducted a multicenter retrospective cohort study among patients with ≥1 newly detected LI-RADS 3 (LR-3) lesion ≥1 cm or LI-RADS 4 (LR-4) lesion of any size (per LI-RADS v2018) between January 2018 and December 2019. Patients were followed with repeat imaging at each site per institutional standard of care.

The progression of cirrhosis with clinically significant portal hypertension towards decompensated cirrhosis remains clinically challenging and the evolution towards acute-on-chronic liver failure (ACLF), with one or more extrahepatic organ failures, is associated with very high mortality. In the last decade, significant progress has been made in the understanding of the mechanisms leading to decompensation and ACLF. As portal hypertension advances, bacterial translocation across an impaired gut barrier culminates in endotoxaemia, systemic inflammation and cirrhosis-associated immune dysfunction (CAID).

Menstruating individuals experience an increased risk for sleep and affective disorders, attributed in part to monthly oscillations in sex hormones. Emotional functioning and sleep continuity worsens during the perimenstrual phase of the menstrual cycle. This study examined the interactive effects of sleep, menstrual phase, and emotion in healthy women.

Further research is needed to help improve both the standard of care and the outcome for patients with treatment-resistant depression. A particularly critical evidence gap exists with respect to whether pharmacological or non-pharmacological augmentation is superior to antidepressant switch, or vice-versa. The objective of this study was to compare the effectiveness of augmentation with aripiprazole or repetitive transcranial magnetic stimulation versus switching to the antidepressant venlafaxine XR (or duloxetine for those not eligible to receive venlafaxine) for treatment-resistant depression.

Healthcare Cost Burden and Self-Reported Frequency of Depressive/Anxious Feelings in Older Adults.

J Gerontol Soc Work

April 2024

Houston VA HSR&D Center for Innovations in Quality, Effectiveness and Safety; Michael E. DeBakey VA Medical Center, Director, VA South Central Mental Illness Research, Education and Clinical Center; and Baylor College of Medicine, Houston, USA.

Using the 2018-2021 National Health Interview Survey data, we examined the associations between healthcare cost burden and depressive/anxious feelings in older adults. Nearly12% reported healthcare cost burden and 18% daily/weekly depressive/anxious feelings. Healthcare cost burden was higher among women, racial/ethnic minorities, those with chronic illnesses, mobility impairment, and those with Medicare Part D, but lower among individuals with Medicare-Medicaid dual eligibility, Medicare Advantage, VA/military insurance, and private insurance.

This commentary discusses how clinicians and various stakeholders can utilize the recently published American Association for the Study of Liver Diseases nonalcoholic fatty liver disease (AASLD NAFLD) Practice Guidance in light of the change in the nomenclature to steatotic liver disease and its subcategories. The new terminologies explained in this commentary make it easier for the readers to interchangeably use metabolic dysfunction-associated steatotic liver disease (MASLD) in place of NAFLD and metabolic-dysfunction associated steatohepatitis (MASH) instead of nonalcoholic steatohepatitis (NASH), respectively, as they read the NAFLD Practice Guidance. The guidance document is relevant and can be utilized for the diagnosis, risk stratification, and management of patients with MASLD.

Intimate partner violence (IPV) and HIV are serious and related public health problems that detrimentally impact women's health. Because women who experience IPV are more likely to acquire HIV, it is critical to promote HIV prevention strategies, such as HIV pre-exposure prophylaxis (PrEP), that increase autonomy. This study of cisgender women eligible for HIV PrEP took place between 2017 and 2019 in Philadelphia and New York City.

Background: Obsessive compulsive disorder (OCD) is effectively treated with exposure and response prevention (ERP), yet very few veterans receive ERP for OCD within the Veterans Health Administration (VHA). Veterans are a clinically complex population, and no prior research has evaluated the effectiveness of ERP in veterans with OCD or comorbid OCD and posttraumatic stress disorder (PTSD). Given the limited accessibility of ERP-trained providers within VHA, assessment of video telehealth (VTH) delivery of ERP is warranted.
