These data show that enterostomy is a potentially morbid condition in the newborn and is prone to complications but should be closed only when the child is in satisfactory nutritional condition.

Background The rates of physical inactivity and related cancer incidence and mortality are disproportionately high in the Deep South region in the United States, a rural, medically underserved region with a large African American population compared with the rest of the nation. Given this region’s lower rates of literacy and internet access, interactive voice response (IVR) system–automated telephone-based interventions have the potential to help overcome physical activity intervention barriers (literacy, internet access, costs, and transportation) but have yet to be extended to rural, underserved populations, such as in the Deep South. Thus, extensive formative research is being conducted to develop and beta test the Deep South IVR System–Supported Active Lifestyle intervention in preparation for dissemination in rural Alabama counties. Objective This paper aims to describe the design and rationale of an ongoing efficacy trial of the Deep South IVR System–Supported Active Lifestyle intervention. Methods A two-arm randomized controlled trial will be conducted to compare a 12-month physical activity intervention versus a wait-list control condition in 240 underactive adults from 6 rural Alabama counties. The Deep South IVR System–Supported Active Lifestyle intervention is based on the Social Cognitive Theory and includes IVR-automated physical activity–related phone counseling (daily in months 0-3, twice weekly in months 4-6, and weekly in months 7-12) and support from local rural county coordinators with the University of Alabama O’Neal Comprehensive Cancer Center Community Outreach and Engagement Office. The primary outcome is weekly minutes of moderate- to vigorous-intensity physical activity (7-day physical activity recall; accelerometry) at baseline, 6 months, 12 months, and 18 months. Rural Active Living Assessments will be conducted in each rural county to assess walkability, assess recreational amenities, and inform future environment and policy efforts. Results This study was funded in March 2019 and approved by the institutional review board of the University of Alabama at Birmingham in April 2019. As of February 2020, start-up activities (hiring and training staff and purchasing supplies) were completed. Study recruitment and assessments began in September 2020 and are ongoing. As of February 2021, a total of 43 participants have been enrolled in Dallas County, 42 in Sumter County, and 51 in Greene County. Conclusions IVR-supported phone counseling has great potential for addressing physical activity barriers (eg, culture, literacy, cost, or transportation) and reducing related rural health disparities in this region.

1. Apolipoprotein B-100 (ApoB) is the principal structural and functional protein of the pro-atherogenic lipoproteins. Elevated plasma apoB is an independent risk factor for coronary artery disease. In the present study we aimed to assess the factors that determine the kinetics of apoB in the very low-density lipoprotein (VLDL) in healthy men. 2. We studied 17 non-obese men who were consuming an ad libitum diet and had the following characteristics: mean (+/-SD) age 45.5 +/- 9.7 years, body mass index (BMI) 25.1 +/- 1.4 kg/m2, waist:hip ratio 0.91 +/- 0.04, serum cholesterol 5.2 +/- 0.6 mmol/L, triglycerides 1.08 +/- 0.53 mmol/L and high-density lipoprotein-cholesterol 1.24 +/- 0.31 mmol/L. Daily dietary intake was as follows: total fat 76 +/- 26 g, carbohydrate 238 +/- 67 g, protein 103 +/- 33 g and alcohol 20 +/- 16 g. 3. The kinetics of VLDL ApoB were studied using a primed, constant infusion (1 mg/kg per h) of 1-[13C]-leucine over 8 h with measurement of isotopic enrichment of ApoB using gas chromatography/mass spectrometry. The fractional turnover rate of VLDL ApoB was estimated using a monoexponential function. The mean (+/-SD) absolute hepatic secretion rate (ASR) of ApoB was 8.5 +/- 4.6 mg/kg per day and the fractional catabolic rate (FCR) was 7.9 +/- 5.6 pools/day. The ASR was significantly correlated with the waist:hip ratio (r = 0.60; P = 0.04), but not with age, BMI, weight or nutrient intake. The FCR was significantly and inversely correlated with plasma triglycerides (r = -0.53; P = 0.03) and alcohol intake (r = -0.48; P = 0.05). 4. In conclusion, the hepatic secretion of VLDL ApoB in nonobese, healthy men is primarily determined by the waist:hip ratio, a measure of visceral fat. This is consistent with the hypothesis that the rate of lipid substrate supply in the liver regulates the output of ApoB. The fractional catabolism of VLDL ApoB may, however, be inversely related to alcohol intake and appears to determine the plasma concentration of triglycerides.
