Curcumin has recently been shown to be a potential treatment for slowing or ameloriating cognitive decline during aging in our nonhuman primate model of normal aging. In these same monkeys, we studied for the first time the neurological impacts of long-term curcumin treatments using longitudinal magnetic resonance imaging (MRI). Sixteen rhesus monkeys received curcumin or a vehicle control for 14–18 months. We applied a combination of structural and diffusion MRI to determine whether the curcumin resulted in structural or functional changes in focal regions of the brain. The longitudinal imaging revealed decreased microscale diffusivity (mD) measurements mainly in the hippocampus and basal forebrain structures of curcumin treated animals. Changes in generalized fractional anisotropy (GFA) and grey matter density (GMd) measurements indicated an increased grey matter density in cortical ROIs with improved white matter integrity in limbic, cerebellar, and brain stem regions. These findings suggest that noticeable changes in the neuronal environment could be induced from long-term curcumin treatments. Results may provide a neurological basis on the recent findings demonstrating improved spatial working memory and motor function in nonhuman primates.

Objective: There is evidence to suggest adverse outcomes on patients’ medical and surgical care when there is language discordance in patient-physician relationships. No studies have evaluated the impact of limited English proficiency (LEP) on complications after common surgical procedures in otolaryngology. Furthermore, no studies have evaluated how patients with LEP utilize remote resources to connect with otolaryngology providers to better triage such complications. The purpose was to evaluate the incidence of post-tonsillectomy hemorrhage (PTH) comparing patients with LEP to those with English proficiency (EP). Patients with PTH were retrospectively evaluated to identify preceding telephone encounters, a marker of resource utilization. Methods: Demographics, English proficiency, and PTH management (surgical vs non-surgical) were evaluated in addition to PTH-associated triage telephone encounters with otolaryngology providers. Results: Of 2466 tonsillectomies, there were 141 episodes of reported hemorrhage (50 LEP vs 91 EP) in the 5 years studied. Rates were not significantly different between LEP and EP patients (4.9% vs 6.3%, P = .127). There was no statistically significant difference in rate of preceding telephone encounters between LEP and EP patients (24% vs 40%, P = .062). Of patients presenting directly to the Emergency Department without a triage telephone encounter, there was no difference in operative versus non-operative management when comparing LEP versus EP patients. However, patients presenting directly to the Emergency Department were nearly twice as likely to undergo operative intervention compared to patients with preceding telephone encounters (RR = 1.79). Conclusion: Patients with limited English proficiency are not at increased risk for developing PTH. There is equitable access to remote otolaryngologic triage care, although overall the utilization rate of this resource was low for both cohorts.
