The effects of breast size in unilateral postmastectomy breast reconstruction.

BACKGROUND: Postmastectomy breast reconstruction is offered to women with breast cancer regardless of body habitus and breast size. The decision regarding technique for breast reconstruction includes patient preference, risk factors, and physical characteristics. The purpose of this study was to determine whether there is a relationship between preoperative breast size and choice of reconstruction, choice of contralateral breast symmetry procedure, and incidence of complications. METHODS: A retrospective review of 355 patients who underwent unilateral breast reconstruction at Emory University from 2005 to 2009 was performed. Patients were stratified into 3 groups based on mastectomy specimen weight with small breasts defined as less than 500 g, medium breasts as 500 to 1000 g, and large breasts as more than 1000 g. Patient demographics were queried including age and risk factors. Additional data points included type of reconstruction, contralateral procedure, and complications. RESULTS: There were 144 patients with small breasts (40.5%), 150 with medium breasts (42.1%), and 62 with large breasts (17.4%). Women with small breasts were equally likely to undergo tissue expander (34%), latissimus dorsi flap (32%), or TRAM/DIEP flap (34%) reconstruction. Women with medium breasts were most likely to undergo TRAM/DIEP reconstruction (47%), whereas women with large breasts were most likely to undergo latissimus dorsi reconstruction (37%; P = 0.134). Small-breasted women were more likely to undergo contralateral augmentation (P < 0.0001), which varied based on the type of reconstruction. Women with medium-sized breasts were more likely to undergo mastopexy (P = 0.033), and large-breasted women were more likely to undergo reduction (P < 0.0001). Women with complications had a greater mean mastectomy weight than women without complications (744 g compared with 620 g, P = 0.0062), and there was an increasing incidence of postoperative wound infections with increasing breast size (18% of large breasts, 7% of medium breasts, and 3% of small breasts; P = 0.0003). CONCLUSIONS: Preoperative breast size does play a role when choosing the most appropriate reconstructive option and symmetry procedure. Being able to adjust the contralateral breast, however, brings the extremes of breast size toward the middle, making most options available regardless of initial size and shape. There are noticeable trends in technique and outcome when stratified by breast size.

Endocrine and metabolic effects of consuming fructose- and glucose-sweetened beverages with meals in obese men and women: influence of insulin resistance on plasma triglyceride responses.

CONTEXT: Compared with glucose-sweetened beverages, consumption of fructose-sweetened beverages with meals elevates postprandial plasma triglycerides and lowers 24-h insulin and leptin profiles in normal-weight women. The effects of fructose, compared with glucose, ingestion on metabolic profiles in obese subjects has not been studied. OBJECTIVE: The objective of the study was to compare the effects of fructose- and glucose-sweetened beverages consumed with meals on hormones and metabolic substrates in obese subjects. DESIGN AND SETTING: The study had a within-subject design conducted in the clinical and translational research center. PARTICIPANTS: Participants included 17 obese men (n = 9) and women (n = 8), with a body mass index greater than 30 kg/m(2). INTERVENTIONS: Subjects were studied under two conditions involving ingestion of mixed nutrient meals with either glucose-sweetened beverages or fructose-sweetened beverages. The beverages provided 30% of total kilocalories. Blood samples were collected over 24 h. MAIN OUTCOME MEASURES: Area under the curve (24 h AUC) for glucose, lactate, insulin, leptin, ghrelin, uric acid, triglycerides (TGs), and free fatty acids was measured. RESULTS: Compared with glucose-sweetened beverages, fructose consumption was associated with lower AUCs for insulin (1052.6 +/- 135.1 vs. 549.2 +/- 79.7 muU/ml per 23 h, P < 0.001) and leptin (151.9 +/- 22.7 vs. 107.0 +/- 15.0 ng/ml per 24 h, P < 0.03) and increased AUC for TG (242.3 +/- 96.8 vs. 704.3 +/- 124.4 mg/dl per 24 h, P < 0.0001). Insulin-resistant subjects exhibited larger 24-h TG profiles (P < 0.03). CONCLUSIONS: In obese subjects, consumption of fructose-sweetened beverages with meals was associated with less insulin secretion, blunted diurnal leptin profiles, and increased postprandial TG concentrations compared with glucose consumption. Increases of TGs were augmented in obese subjects with insulin resistance, suggesting that fructose consumption may exacerbate an already adverse metabolic profile present in many obese subjects.
