Efficacy of supplemental MCT oil on seizure reduction of adult drug-resistant epilepsy - a single-center open-label pilot study.

OBJECTIVE: We set out to determine whether adding medium chain triglyceride (MCT) oil as a dietary supplement to standard diet in adult subjects with intractable epilepsy in a U.S. neurology clinical practice was associated with a reduction in number of seizures. We secondarily aimed to determine whether subjects experienced any side effects and whether there was a presence of urinary ketones while using MCT oil as a dietary supplement. METHODS: Adult patients with intractable epilepsy were recruited at standard of care clinical visits with their epileptologist. Once enrolled, subjects were instructed to supplement their diet with MCT oil as tolerated twice daily for three months (including a 1-2 week titration period, followed by a 1-2 week tapering off window) while keeping a seizure diary to record total number of seizures, presence of urinary ketones, and any side effects. RESULTS: Our data although limited by small sample size, shows that there is an estimated 42% reduction (p < 0.0001) in the rate of seizures. The MCT oil supplementation was well tolerated by most subjects except for minor GI side effects like nausea and loose stools. Most subjects developed ketones in their urine at some point during the trial. CONCLUSIONS: MCT oil supplementation reduced seizure frequency in study participants. The reported side effects included mild nausea, stomachache, loose stools. A placebo-controlled study will be more informative.

Functional genomics and metabolomics advance the ethnobotany of the Samoan traditional medicine "matalafi".

The leaf homogenate of Psychotria insularum is widely used in Samoan traditional medicine to treat inflammation associated with fever, body aches, swellings, wounds, elephantiasis, incontinence, skin infections, vomiting, respiratory infections, and abdominal distress. However, the bioactive components and underlying mechanisms of action are unknown. We used chemical genomic analyses in the model organism Saccharomyces cerevisiae (baker's yeast) to identify and characterize an iron homeostasis mechanism of action in the traditional medicine as an unfractionated entity to emulate its traditional use. Bioactivity-guided fractionation of the homogenate identified two flavonol glycosides, rutin and nicotiflorin, each binding iron in an ion-dependent molecular networking metabolomics analysis. Translating results to mammalian immune cells and traditional application, the iron chelator activity of the P. insularum homogenate or rutin decreased proinflammatory and enhanced anti-inflammatory cytokine responses in immune cells. Together, the synergistic power of combining traditional knowledge with chemical genomics, metabolomics, and bioassay-guided fractionation provided molecular insight into a relatively understudied Samoan traditional medicine and developed methodology to advance ethnobotany.

The potential for DHA to mitigate mild traumatic brain injury.

Scientific knowledge of omega-3 fatty acids (FAs) has grown in the last decade to a greater understanding of their mechanisms of action and their potential therapeutic effects. Omega-3 FAs have shown therapeutic potential with respect to hyperlipidemia, depression, attention-deficit hyperactivity disorder, and mild cognitive impairment. Laboratory evidence and clinical interest have grown such that omega-3 FAs have now assumed a role in concussion management. This has coincided with recent research that has also helped to increase the scientific understanding of cerebral concussion; although concussion or mild traumatic brain injury was assumed to be a malfunctioning brain without anatomical damage, we now know that there is the potential for damage and dysfunction at the cellular and microstructural levels. Specifically, with concussion abnormal metabolism of glucose may occur and intracellular mitochondrial dysfunction can persist for several days. In this article, we discuss the role of omega-3 FAs, particularly docosahexaenoic acid, in concussion management.
