Although bariatric surgery has become more accessible in recent years, it is unclear whether populations disproportionately affected by obesity are utilizing this treatment. A cross-sectional analysis of the Nationwide Inpatient Sample was performed. The sociodemographic characteristics (race, sex, age, insurance, median income), co-morbidities, and weight loss surgery type were analyzed. Bariatric surgeries increased six-fold from 17,678 in 1998 to 112,882 in 2004 (p < 0.001). Thereafter, bariatric surgeries declined to 93,733 in 2007 (p = 0.24). The proportion of individuals of Other race undergoing bariatric surgery significantly increased, while the proportion of Whites significantly decreased over time. The proportion of individuals in the lowest income quartile (< $25,000) increased, while those in the highest income percentile (> $45,000) decreased. From 1998 to 2007, the sociodemographic characteristics of the bariatric surgery population have changed, although those that are disproportionately affected by morbid obesity continue to be underrepresented.

    ABSTRACT: Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) is the most effective treatment for morbid obesity. The additional benefit of placing a nonadjustable band around the pouch remains to be determined. The objective of this study was to compare outcomes between banded and nonbanded LRYGB patients in a single bariatric center. Methods: A matched cohort analysis was performed between patients who had undergone banded and nonbanded (standard) LRYGB. In the banded bypass cohort, an 8 F, 6.5 cm silastic ring was placed around the proximal gastric pouch. Both cohorts were matched for age, body mass index (BMI), and anastomotic technique. Endpoints included percentage excess weight loss (%EWL), postoperative morbidity, and band-related complications. Results: Between January 2007 and July 2010, 134 banded LRYGB were performed (55% female, mean age 45 years). They were compared with a matched cohort of 134 concurrent nonbanded LRYGB patients (67% female, mean age 45.4 years). Mean preoperative BMI was 54.6 and 52.8 kg/m(2), respectively (P = .084). At 24 months postoperatively, the average %EWL was 58.6% in banded bypass patients and 51.4% in the nonbanded group (P = .015). The difference in EWL was more pronounced in super-obese patients than in those with BMI<50 (among super-obese, 57.5% versus 47.6%, P = .003; among those with BMI<50, 62.9% versus 57.9%, P = .406]. There was no difference in early (19.4% versus 19.4%) or late complications (10.4% versus 13.4%, P = .451) between banded and nonbanded LRYGB patients. Conclusion: Banding the pouch during LRYGB can be performed safely and may provide better weight loss, particularly in super-obese patients. Further prospective and long-term comparative studies of this technique are warranted.

    ABSTRACT: Choline metabolism is important for very low-density lipoprotein secretion, making this nutritional pathway an important contributor to hepatic lipid balance. The purpose of this study was to assess whether the cumulative effects of multiple single nucleotide polymorphisms (SNPs) across genes of choline/1-carbon metabolism and functionally related pathways increase susceptibility to developing hepatic steatosis. In biopsy-characterized cases of nonalcoholic fatty liver disease and controls, we assessed 260 SNPs across 21 genes in choline/1-carbon metabolism. When SNPs were examined individually, using logistic regression, we only identified a single SNP (PNPLA3 rs738409) that was significantly associated with severity of hepatic steatosis after adjusting for confounders and multiple comparisons (P=0.02). However, when groupings of SNPs in similar metabolic pathways were defined using unsupervised hierarchical clustering, we identified groups of subjects with shared SNP signatures that were significantly correlated with steatosis burden (P=0.0002). The lowest and highest steatosis clusters could also be differentiated by ethnicity. However, unique SNP patterns defined steatosis burden irrespective of ethnicity. Our results suggest that analysis of SNP patterns in genes of choline/1-carbon metabolism may be useful for prediction of severity of steatosis in specific subsets of people, and the metabolic inefficiencies caused by these SNPs should be examined further.-Corbin, K.

Genetic signatures in choline and 1-carbon metabolism are associated with the severity of hepatic steatosis.

    ABSTRACT: Under-representation of ethnic minority groups in bariatric surgery rates has been reported in the USA. Ethnic minorities form 7.9 % of the UK population, but comparable data on provision of bariatric surgery for these groups have not previously been reported in the UK. We calculated an estimate of rates of bariatric surgery amongst ethnic groups in the UK and Ireland using data from the National Bariatric Surgery Registry and census data from the UK and Ireland. The number of procedures recorded per 1,000 morbidly obese patients was 5.2 for Caucasian patients, 5.2 for Asian patients and 5.2 for Black patients. The identical rates across different ethnic groups suggest that bariatric services are provided equitably in the UK, with ethnic minority groups achieving equal access.
