- Systemic inflammation and carotid diameter in obese patients: pilot comparative study with flaxseed powder and cassava powder(2011) FAINTUCH, J.; BORTOLOTTO, L. A.; MARQUES, P. C.; FAINTUCH, J. J.; FRANCA, J. I.; CECCONELLO, I.Background: Botanical omega-3 fatty acid (alpha-linolenic acid/ALA) has been shown to alleviate the prothrombotic and proinflammatory profile of metabolic syndrome, however clinical protocols are still scarce. Aiming to focus an obese population, a pilot study was designed. Methods: Morbidly obese candidates for bariatric surgery (n = 29, age 463 +/- 5.2 years), 82.8% females (24/29), BMI 44.9 +/- 5.2 kg/m(2), with C-reactive protein/CRP > 5 mg/L were recruited. Twenty were randomized and after exclusions, 16 were available for analysis. Flaxseed powder (60 g/day, 10 g ALA) and isocaloric roasted cassava powder (60 g/day, fat-free) were administered in a double-blind routine for 12 weeks. Results: During flaxseed consumption neutrophil count decreased and fibrinogen, complement C4, prothrombin time and carotid diameter remained stable, whereas placebo (cassava powder) was associated with further elevation of those measurements. Conclusions: Inflammatory and coagulatory markers tended to exhibit a better outlook in the flaxseed group. Also large-artery diameter stabilized whereas further increase was noticed in controls. These findings raise the hypothesis of a less deleterious cardiovascular course in seriously obese subjects receiving a flaxseed supplement. (Nutr Hosp. 2011;26:208-213) DOI:10.3305/nh.2011.26.1.4974
- Four-Year Hospital Resource Utilization After Bariatric Surgery: Comparison with Clinical and Surgical Controls(2011) HAYASHI, Silvia Yoko; FAINTUCH, Joel; FRANCA, Joao Italo Dias; CECCONELLO, IvanConsumption of healthcare has been shown to diminish after bariatric treatment, but utilization of hospital services has not been well documented. Aiming to assess this question, a retrospective study with females was designed. Yearly outpatient appointments, hospital admissions, emergency department visits, and total biochemical tests during 4 years were registered and compared with the preoperative year. Population (N = 176, all females) comprised 94 bariatric candidates submitted to Roux-en-Y gastric bypass (RYGB; age 41.4 +/- 10.1 years, BMI 52.2 +/- 10.6 kg/m(2)), 34 nonoperated obese controls (age 49.4 +/- 8.3 years, BMI 33.8 +/- 5.5 kg/m(2)), and 48 colorectal surgical controls (age 44.8 +/- 8.6 years, BMI 23.8 +/- 4.7 kg/m(2)). Nonbariatric obese patients were fairly well-matched, moderate differences involving higher age and comorbidities. Surgical controls were similarly aged but suffered from less comorbidities. Obese nonsurgical participants displayed the highest demand for outpatient visits (10.5 +/- 0.9/year, P < 0.001) followed by bariatric and colorectal cases (5.7 +/- 0.2 and 3.5 +/- 0.8, respectively, P = 0.042). Also biochemical measurements were most often required by clinical controls (61.5 +/- 5.1/year, P < 0.001), whereas no difference was detected between bariatric and colorectal patients (28.9 +/- 2.2 and 33.8 +/- 7.7/year, respectively). Elective and emergency admissions were similar for all groups, and part of the postbariatric assistance was related to plastic surgery. RYGB patients needed 45.8% less outpatient visits and 53.0% less laboratory tests than nonoperated moderately obese cases, even including esthetic operations. Results were comparable to those observed after elective colorectal surgery and remained fairly stable during 4 years.
