The incidence of esophageal adenocarcinoma (EA) and its precursor condition, Barrett's esophagus, has risen rapidly in the United States for reasons that are not fully understood. Therefore, we evaluated the association between use of supplemental vitamins and minerals and risk of neoplastic progression of Barrett's esophagus and EA. The Seattle Barrett's Esophagus Program is a prospective study based on 339 men and women with histologically confirmed Barrett's esophagus. Participants underwent baseline and periodic follow-up exams, which included endoscopy and self-administered questionnaires on diet, supplement use, and lifestyle characteristics. Use of multivitamins and 4 individual supplements was calculated using time-weighted averages of reported use over the observational period. Cox proportional-hazards models were used to calculate hazard ratios (HR) for each endpoint: EA, tetraploidy, and aneuploidy. During a mean follow-up of 5 yr, there were 37 cases of EA, 42 cases of tetraploidy, and 34 cases of aneuploidy. After controlling for multiple covariates including diet, nonsteroidal anti-inflammatory drug use, obesity, and smoking, participants who took 1 or more multivitamin pills/day had a significantly decreased risk of tetraploidy [HR = 0.19; 95% confidence interval (CI) = 0.08-0.47) and EA (HR = 0.38; 95% CI = 0.15-0.99] compared to those not taking multivitamins. Significant inverse associations were also observed between risk of EA and supplemental vitamin C (>or = 250 mg vs. none: HR = 0.25; 95% CI = 0.11-0.58) and vitamin E (>or = 180 mg vs. none: HR = 0.25; 95% CI = 0.10-0.60). In this cohort study, use of multivitamins and single antioxidant supplements was associated with a significantly reduced risk of EA and markers of neoplastic progression among individuals with Barrett's esophagus.

BACKGROUND: Most moderate-severe juvenile Crohn's disease (CD) patients are in a constant catabolic state resulting in poor weight gain and growth failure. Anti-inflammatory, immunomodulatory, and monoclonal antibody drugs, as well as growth hormone (GH), frequently fail to achieve sustained remission or reverse growth failure.

OBJECTIVE: To test whether an exclusion diet with nutraceutical therapy (DNT) could induce sustained clinical remission and weight gain, and if so does this enhance the ability for GH to reverse growth failure.

METHODS: An uncontrolled prospective case study was undertaken in six moderate- severe CD patients, two of whom had completed growth. All were treated with DNT. Adequate caloric and protein (>/= 3g/kg/d) intake for catch up weight was prescribed. Dairy products, certain grains and carrageenan containing foods were eliminated. Nutraceuticals, consisting of fish peptides, bovine colostrum, boswellia serrata, curcumin and a multivitamin were administered daily. Lactobacillus GG, a probiotic, was administered twice weekly. Recombinant human GH (rhGH) was administered daily.

RESULTS: Within 2 months of starting DNT all six patients went into remission, with discontinuation of all pharmacological drugs. Three patients have remained in sustained remission for 4 to 8 years. One patient with very severe CD had recurrence of CD symptoms after being in complete remission for 18 months, one patient was in remission for 3 years but symptoms recurred when she became less compliant to DNT and one recently treated patient remains in remission after 6 months. With the addition of rhGH, the 4 growing patients had good-excellent growth response

CONCLUSION: DNT engendered prolonged remission and restoration of normal weight in moderate-severe juvenile CD patients, providing conditions that enabled rhGH to stimulate growth. These findings justify larger controlled trials to evaluate the long-term benefit of compliance to DNT in both juvenile and adult CD patients.

BACKGROUND:Telomere length may be a marker of biological aging. Multivitamin supplements represent a major source of micronutrients, which may affect telomere length by modulating oxidative stress and chronic inflammation.

OBJECTIVE:The objective was to examine whether multivitamin use is associated with longer telomeres in women.

DESIGN:We performed a cross-sectional analysis of data from 586 early participants (age 35-74 y) in the Sister Study. Multivitamin use and nutrient intakes were assessed with a 146-item food-frequency questionnaire, and relative telomere length of leukocyte DNA was measured by quantitative polymerase chain reaction.

RESULTS:After age and other potential confounders were adjusted for, multivitamin use was associated with longer telomeres. Compared with nonusers, the relative telomere length of leukocyte DNA was on average 5.1% longer among daily multivitamin users (P for trend = 0.002). In the analysis of micronutrients, higher intakes of vitamins C and E from foods were each associated with longer telomeres, even after adjustment for multivitamin use. Furthermore, intakes of both nutrients were associated with telomere length among women who did not take multivitamins.

CONCLUSION:This study provides the first epidemiologic evidence that multivitamin use is associated with longer telomere length among women.

Brain injuries are common in professional American football players. Finding effective rehabilitation strategies can have widespread implications not only for retired players but also for patients with traumatic brain injury and substance abuse problems. An open label pragmatic clinical intervention was conducted in an outpatient neuropsychiatric clinic with 30 retired NFL players who demonstrated brain damage and cognitive impairment. The study included weight loss (if appropriate); fish oil (5.6 grams a day); a high-potency multiple vitamin; and a formulated brain enhancement supplement that included nutrients to enhance blood flow (ginkgo and vinpocetine), acetylcholine (acetyl-l-carnitine and huperzine A), and antioxidant activity (alpha-lipoic acid and n-acetyl-cysteine). The trial average was six months. Outcome measures were Microcog Assessment of Cognitive Functioning and brain SPECT imaging. In the retest situation, corrected for practice effect, there were statistically significant increases in scores of attention, memory, reasoning, information processing speed and accuracy on the Microcog. The brain SPECT scans, as a group, showed increased brain perfusion, especially in the prefrontal cortex, parietal lobes, occipital lobes, anterior cingulate gyrus and cerebellum. This study demonstrates that cognitive and cerebral blood flow improvements are possible in this group with multiple interventions.
