I am faculty member at Florida Gulf Coast University with 15 years of clinical exercise physiology experience. I plan to apply my clinical and research experience to further our understanding of how exercise improves the lives of those with chronic diseases and help train the next generation of exercise scientists.

BACKGROUND: Extremely obese adolescents are increasingly undergoing bariatric procedures, which restrict dietary intake. However, as yet, no data are available describing the change in caloric density or composition of the adolescent bariatric patient's diet pre- and postoperatively. Our objective was to assess the 1-year change in the dietary composition of adolescents undergoing bariatric surgery at a tertiary care children's hospital. METHODS: A total of 27 subjects (67% female, 77% white, age 16.7 ± 1.4 yr, baseline body mass index 60.1 ± 14.1 kg/m(2)) were prospectively enrolled into an observational cohort study 1 month before undergoing laparoscopic Roux-en-Y gastric bypass from August 2005 to March 2008. The 3-day dietary intake was recorded at baseline (n = 24) and 2 weeks (n = 16), 3 months (n = 11), and 1 year (n = 9) postoperatively. The dietary record data were verified by structured interview and compared with the Dietary Reference Intake values for ages 14-18 years. RESULTS: By 1 year after surgery, the mean caloric intake, adjusted for body mass index was 1015 ± 182 kcal/d, a 35% reduction from baseline. The proportion of fat, protein, and carbohydrate intake did not differ from baseline. However, the protein intake was lower than recommended postoperatively. The calcium and fiber intake was also persistently lower than recommended. Calcium and vitamin B(12) supplementation increased the likelihood of meeting the daily minimal recommendations (P ≤ .02). CONCLUSION: At 1 year after Roux-en-Y gastric bypass, the adolescents' caloric intake remained restricted, with satisfactory macronutrient composition but a lower than desirable intake of calcium, fiber, and protein. Comment on: Dietary assessment of adolescents undergoing laparoscopic Roux-en-Y gastric bypass surgery: macro- and micronutrient, fiber and supplement intake.

Abstract OBJECTIVE: To test the null hypothesis that, after 28 weeks of gestation, uterine blood flow during supine rest and supine exercise is no different than uterine blood flow at left-lateral rest. DESIGN: In vivo experimental study in pregnant women. SETTING: Department of Obstetrics, MetroHealth Medical Center, Cleveland, OH, USA. POPULATION: Fourteen, physically active, late-pregnant women who continued supine exercise throughout gestation. METHODS: Studies were carried out between 29 and 38 weeks of gestation. Maternal blood pressure, maternal heart rate, and ultrasound estimates of volume blood flow in the right ascending branch of the uterine artery were obtained serially at rest in the left-lateral position, at rest in the supine position, during and immediately after 10 minutes of supine exercise, and again at rest in the left-lateral position. Exercise sessions included alternating 60- to 90-second periods of abdominal crunches and leg exercise at moderate/high intensity (Borg's rating of perceived exertion 14 +/- 1). MAIN OUTCOME MEASURES: Blood pressure, heart rate, and uterine artery volume flow. RESULTS: Data are presented as the mean +/- SD. Maternal heart rate and blood pressure were unchanged at supine rest but increased during supine exercise (heart rate increased from 76 +/- 9 to 98 +/- 12 beats per minute, mean arterial pressure increased from 81 +/- 6 to 102 +/- 12 mmHg). Volume flow fell from 410 +/- 93 to 267 +/- 73 cc/minute after 5 minutes of supine rest and then, during supine exercise, increased to 355 +/- 125 cc/minute. Uterine artery luminal diameter and blood flow correlated directly with tissue weights at birth (r(2) values between 0.32 and 0.59). CONCLUSIONS: In physically active women, uterine blood flow decreases during both supine rest and supine exercise but the decrease in the former is twice that seen in the latter.
