- Does Roux-en-Y gastrectomy for gastric cancer influence glucose homeostasis in lean patients?(2013) HAYASHI, Silvia Y.; FAINTUCH, Joel; YAGI, Osmar K.; YAMAGUCHI, Camila M.; FAINTUCH, Jacob J.; CECCONELLO, IvanCancer gastrectomy seems to benefit type 2 diabetes; however, results are conflicting. In a prospective protocol, including retrospective information, the aim was assessment of changes in glucose profile in patients with both normal and deranged preoperative glucose homeostasis. Patients (N = 164) with curative subtotal or total Roux-en-Y gastrectomy for gastric cancer (n = 92), or Roux-en-Y gastric bypass for morbid obesity (RYGB, n = 72) were preoperatively classified into diabetes (including prediabetes) and control group. Postoperative diabetes outcome was stratified as responsive or refractory, and results in controls were correspondingly defined as stable or new-onset diabetes (NOD), according to fasting blood glucose and HbA1c. Dietary intake and biochemical profile was documented. Statistical methods included analysis of variance, multivariate logistic regression, and propensity score matching according to postoperative weight loss. Age of cancer cases was 67.9 +/- A 11.5 years, 56.5 % males, initial body mass index (BMI) 24.7 +/- A 3.7, current BMI 22.6 +/- A 3.8 kg/m(2), and follow-up 102.1 +/- 51.0 months, whereas in bariatric individuals age was 51.4 +/- A 10.1 years, 15.3 % males, initial BMI 56.7 +/- A 12.2, current BMI 34.8 +/- A 8.1 kg/m(2), and follow-up 104.1 +/- 29.7 months. Refractory disease corresponded to 62.5 % (cancer) versus 23.5 % (bariatric) (P = 0.019), whereas NOD represented 69.2 versus 23.8 % respectively (P = 0.016). Weight loss (Delta BMI) was associated with diabetes response in cancer patients but not with NOD. No difference between subtotal and total gastrectomy was detected. Divergent outcomes (refractory vs. responsive) were confirmed in BMI-similar, propensity-matched cancer gastrectomy patients with preoperative diabetes, consistent with weight-dependent and -independent benefits. Diabetes response was confirmed, however with more refractory cases than in bariatric controls, whereas high proportions of NOD occurred. Such dichotomous pattern seems unusual albeit consistent with previous studies.
- 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
- Refractory and new-onset diabetes more than 5 years after gastric bypass for morbid obesity(2012) YAMAGUCHI, Camila M.; FAINTUCH, Joel; HAYASHI, Silvia Y.; FAINTUCH, Jacob J.; CECCONELLO, IvanFew studies about long-term glucose homeostasis in bariatric patients are available. In a prospective protocol that included retrospective information, outcome of patients with both impaired and normal fasting blood glucose (FBG) was monitored to assess frequencies and correlates. Patients submitted to Roux-en-Y gastric bypass were classified as group I, elevated FBG, and group II, normal controls. Those in group I with improvement in FBG were defined as responsive and the others as refractory. Group II participants progressing to new-onset diabetes (NOD) or prediabetes represented NOD cases; the remaining were listed as stable controls. FBG was the main endpoint, but HbA1c results were considered, along with diet composition and general biochemical profile. Among 97 selected patients, 51 belonged to group I (52.4 +/- A 10.5 years, 29.6 % males, initial body mass index (BMI) 58.4 +/- A 13.4, current BMI 35.1 +/- A 8.4 kg/m(2)) and 46 to group II (48.2 +/- A 10.5 years, 19.6 % males, initial BMI 55.5 +/- A 8.8, current BMI 33.9 +/- A 6.9 kg/m(2)). Follow-up was 7-9 years, and 31.4 % (16/51) of group I were classified as refractory, whereas 15.2 % (7/46) of the controls converted to NOD. Multivariate analysis pointed out higher current BMI, older age, consumption of antidiabetic drugs, and male gender as features of refractory cases, whereas NOD participants were not significantly different from non-progressing controls. This is the first investigation, to the best of our knowledge, to underscore the correlates of refractory and NOD within the bariatric context. Further studies are recommended as such information could be valuable for patient selection, prognostic scoring, and outcome monitoring.
- Endoscopic findings in uninvestigated dyspepsia(2014) FAINTUCH, Jacob Jehuda; SILVA, Fernando Marcuz; NAVARRO-RODRIGUEZ, Tomas; BARBUTI, Ricardo Correa; HASHIMOTO, Claudio Lyoiti; ROSSINI, Alessandra Rita Asayama Lopes; DINIZ, Marcio Augusto; EISIG, Jaime NatanBackground: It is important to know the causes of dyspepsia to establish the therapeutic approach. Dyspepsia is a frequent syndrome in our country, where there are restrictions to endoscopy and high prevalence of Helicobacter pylori (H. pylori) infection. This study aimed to assess the endoscopic findings of the syndrome, in an outpatient screening clinic of a tertiary hospital in Sao Paulo. Methods: Outpatients with uninvestigated dyspepsia, according to Rome III criteria, answered a dyspepsia questionnaire and underwent esophagogastroduodenoscopy. The Rapid Urease Test was applied to fragments of the antral mucosa and epidemiological data were collected from the studied population. Organic dyspepsia findings were analyzed with different variables to verify statistically significant associations. Results: Three hundred and six patients were included and 282 were analyzed in the study. The mean age was 44 years and women comprised 65% of the sample. Forty-five percent of the patients reported alarm symptoms. Functional dyspepsia was found in 66% of the patients (20% with normal endoscopy results and 46% with gastritis), 18% had GERD and 13% had ulcers (duodenal in 9% and gastric in 4%). Four cases of gastric adenocarcinoma were identified (1.4%), one without alarm characteristics, 1 case of adenocarcinoma of the distal esophagus and 1 case of gastric lymphoma. The prevalence of H. pylori was 54% and infection, age and smoking status were associated with organic dyspepsia. The age of 48 years was indicative of alarm signs. Conclusions: The endoscopic diagnosis of uninvestigated dyspepsia in our setting showed a predominance of functional disease, whereas cancer was an uncommon finding, despite the high prevalence of H. pylori. Organic dyspepsia was associated with infection, age and smoking status.
