Alabama Veterans Rural Health Initiative: a pilot study of enhanced community outreach in rural areas.

PURPOSE: Access, enrollment, and engagement with primary and specialty health care services present significant challenges for rural populations worldwide. The Alabama Veterans Rural Health Initiative evaluated an innovative outreach intervention combining motivational interviewing, patient navigation, and health services education to promote utilization of the United States Veterans Administration Healthcare System (VA) by veterans who live in rural locations. METHODS: Community outreach workers completed the intervention and assessment, enrolling veterans from 31 counties in a southern state. A total 203 participants were randomized to either an enhanced enrollment and engagement outreach condition (EEE, n = 101) or an administrative outreach (AO, n = 102) condition. FINDINGS: EEE participants enrolled and attended VA appointments at higher rates and within fewer days than those who received AO. Eighty-seven percent of EEE veterans attended an appointment within 6 months, compared to 58% of AO veterans (P < .0001). The median time to first appointment was 12 days for the EEE group and 98 days for the AO group (P < .0001). Additionally, a race by outreach group interaction emerged: black and white individuals benefited equally from the EEE intervention; however, black individuals who received AO took significantly longer to attend appointments than their white counterparts. CONCLUSIONS: Results provide needed empirical support for a specific outreach intervention that speeds enrollment and engagement for rural individuals in VA services. Planned interventions to improve service utilization should ameliorate ambivalence about accessing health care in addition to addressing traditional systems or environmental-level barriers.

Seizure susceptibility and epileptogenesis in a rat model of epilepsy and depression co-morbidity.

Although a strong co-morbidity exists clinically between epilepsy and depression, the cause of this co-morbidity remains unknown, and a valid animal model is crucial for the identification of underlying mechanisms and the development of a screening tool for novel therapies. Although some rodent models of epilepsy have been reported to display behaviors relevant to affective disorders, the seizure susceptibility of animals prone to depression-like behavior has not been characterized. Toward this end, we assessed several forms of seizure sensitivity and epileptogenesis in rats selectively bred for vulnerability (Swim Lo-Active; SwLo) or resilience (Swim High-Active; SwHi) to depression-like phenotypes. The SwLo rats exhibit decreased motor activity in a swim test and other depression-like phenotypes, whereas the SwHi rats display increased motor activity in a swim test. SwLo rats exhibited a decreased latency to limbic motor seizures following acute pilocarpine administration in the absence of differences in pilocarpine pharmacokinetics, and also had a decreased threshold to tonic seizures induced by electroshock. Approximately half of the SwLo rats, but none of the SwHi rats, had spontaneous limbic motor seizures 5 weeks following pilocarpine-induced status epilepticus. While the number of stimulations required to achieve full amygdala and hippocampal electrical kindling were similar in the two rat lines, SwLo rats had a lower final hippocampal kindling threshold and more wet dog shakes during both amygdala and hippocampal kindling. Combined, these results indicate that SwLo rats are a model of epilepsy and depression co-morbidity that can be used for investigating underlying neurobiological and genetic mechanisms and screening novel therapeutics.
