Improving Geropsychology Competencies of Veterans Affairs Psychologists.

Older adults are more likely to seek mental health care through integrated care settings such as primary care. Currently, there exists a significant shortage of mental health providers trained in geropsychology and integrated care competencies. To address this need within the Veterans Health Administration, a national workforce development program was extended to include psychologists, which is called the Geriatric Scholars Program-Psychology Track (GSP-P). The GSP-P has two overarching educational program aims: (1) to improve geropsychology competencies of practicing VA psychologists, particularly those working within integrated settings (e.g., primary care) and (2) enrich psychologists' abilities to enact change in their clinical settings. Ninety-eight VA clinicians participated in the GSP-P, which includes a multi-day in-person course, from 2014 to 2018. Participants completed measures assessing confidence and self-reported knowledge in geropsychology and integrated care competencies pre-course and 3-months post-completion. Two-weeks post-course participants responded to open-ended survey questions regarding their perceptions of the course and potential applications of learning. Significant improvements in confidence in and knowledge of geropsychology and integrated care competencies emerged from pre-course to 3-months post-completion. Qualitative findings demonstrated that participants valued the face-to-face, integrated multimodal educational program. Findings provided insights regarding clinicians' planned application of the knowledge acquired, such as modifying treatments for older patients. Specialized workforce programs such as the GSP-P have a significant, positive impact on the care of older Veterans.

Differential effects of minocycline on microglial activation and neurodegeneration following closed head injury in the neonate rat.

The role of microglia in the pathophysiology of injury to the developing brain has been extensively studied. In children under the age of 4 who have sustained a traumatic brain injury (TBI), markers of microglial/macrophage activation were increased in the cerebrospinal fluid and were associated with worse neurologic outcome. Minocycline is an antibiotic that decreases microglial/macrophage activation following hypoxic-ischemia in neonatal rodents and TBI in adult rodents thereby reducing neurodegeneration and behavioral deficits. In study 1, 11-day-old rats received an impact to the intact skull and were treated for 3days with minocycline. Immediately following termination of minocycline administration, microglial reactivity was reduced in the cortex and hippocampus (p<0.001) and was accompanied by an increase in the number of fluoro-Jade B profiles (p<0.001) suggestive of a reduced clearance of degenerating cells; however, this effect was not sustained at 7days post-injury. Although microglial reactivity was reduced in the white matter tracts (p<0.001), minocycline treatment did not reduce axonal injury or degeneration. In the thalamus, minocycline treatment did not affect microglial reactivity, axonal injury and degeneration, and neurodegeneration. Injury-induced spatial learning and memory deficits were also not affected by minocycline. In study 2, to test whether extended dosing of minocycline may be necessary to reduce the ongoing pathologic alterations, a separate group of animals received minocycline for 9days. Immediately following termination of treatment, microglial reactivity and neurodegeneration in all regions examined were exacerbated in minocycline-treated brain-injured animals compared to brain-injured animals that received vehicle (p<0.001), an effect that was only sustained in the cortex and hippocampus up to 15days post-injury (p<0.001). Whereas injury-induced spatial learning deficits remained unaffected by minocycline treatment, memory deficits appeared to be significantly worse (p<0.05). Sex had minimal effects on either injury-induced alterations or the efficacy of minocycline treatment. Collectively, these data demonstrate the differential effects of minocycline in the immature brain following impact trauma and suggest that minocycline may not be an effective therapeutic strategy for TBI in the immature brain.
