Micronutrient Therapy for Violent and Aggressive Male Youth: An Open-Label Trial.

OBJECTIVES: Pharmacotherapy for problematic aggressive and violent behavior disorders in male children and adolescents is associated with significant adverse events. Treatments with more acceptable risk-benefit ratios are critically needed. Micronutrient intervention will be investigated as an alternative to bridge the therapeutic gap in the management of these behaviors. METHODS: Males aged 4-14 who displayed ongoing violent and aggressive behaviors received micronutrient intervention containing alpha-tocopherol (vitamin E), ascorbic acid (vitamin C), biotin, chromium, pyridoxal-5-phosphate (P5P), pyridoxine (vitamins B6), selenium, and zinc, in a 16-week open-label trial. Plasma zinc, plasma copper, copper/zinc ratio, and urinary hydroxyhemopyrroline-2-one (HPL) tests were conducted at baseline and endpoint. Participants were examined for changes in aggressive and violent behaviors measured using the Children's Aggression Scale (CAS) and the Modified Overt Aggression Scale (MOAS), improvements in family functioning measured using the Family Functioning Style Scale, improvements in health-related quality of life (HRQoL) measured using the Pediatric Quality of Life Inventory (PedsQL) at baseline, 8 weeks, endpoint, and at 4-6-month follow-up. RESULTS: Thirty-two male children and adolescents met inclusion criteria. Thirty-one (mean 8.35 ± standard deviation 2.93 years) completed the study, with one participant lost to follow-up. Micronutrient therapy significantly improved parent-reported aggressive and violent behaviors measured using the CAS for all domains except the use of weapons (p < 0.001 to p = 0.02) with medium to large effect size (Cohen's d = 0.72-1.43) and the MOAS (p < 0.001) with large effect size (Cohen's d = 1.26). Parent-reported HRQoL (p < 0.001; Cohen's d = -1.69) and family functioning (p = 0.03; Cohen's d = -0.41) also significantly improved. CONCLUSION: Micronutrient therapy appeared well tolerated, with a favorable side effect profile. It appeared effective in the reduction of parent-reported aggressive and violent behaviors, and showed improvement in family functioning and HRQoL in male youth after 16 weeks. Further research in the form of a double-blinded, randomized controlled trial is required to verify these initial positive observations.

Adjustable gastric band placed around gastric bypass pouch as revision operation for failed gastric bypass.

BACKGROUND: The failure rate after gastric bypass surgery for weight loss has been reported at 10-20%. To date, no reliably safe and effective salvage operation is available. This pilot study was conducted to determine whether restriction of the Roux-en-Y gastric bypass (RYGB) pouch using the adjustable gastric band (AGB) is an effective revision operation. METHODS: A prospectively accrued group of patients who underwent revisional surgery using the AGB placed around the RYGB pouch by our bariatric surgical group from October 2004 to October 2006 was analyzed. RESULTS: Of the 10 patients accrued during this period, 2 were lost to follow-up, leaving 8 patients for analysis. Of the 8 patients, 1 was a man and 7 were women. The mean prerevision weight was 135.75 kg (range 105-165), and the body mass index was 48.42 kg/m(2) (range 38.92-55). The mean weight loss at 1 year of follow-up was 17.03 kg (range 0.2-42), with a mean percentage of excess weight loss of 24.29% (range 0.2-49.2%). The mean weight loss of the 5 patients with 2 years of follow-up was 36.4 kg (range 20-58), with a mean percentage of excess weight loss of 48.7% (range 21.8-98.1%). One patient with 3 years of follow-up had a weight loss of 56 kg and a percentage of excess weight loss of 66.2%. Three minor complications developed: 2 AGB port-related complications requiring port revision and 1 postoperative wound hematoma requiring evacuation. No band erosions or band slippages occurred, and no major complications developed. CONCLUSION: In our study, an AGB placed around the RYGB pouch was a safe and effective revision operation for a failed RYGB operation.
