Impact of bariatric surgery on oral health conditions: 6-months cohort study.

Objectives: We evaluate oral health conditions before and after bariatric surgery.

Methods: The sample was composed of 59 patients who had undergone Roux-en-Y gastric bypass (RYGB). Salivary flow, periodontal pocket depth and dental wear were evaluated before and after 6 months of surgery.

Are knee and foot orthopedic problems more disabling in the superobese?

Background: Aiming to ascertain whether frequency and severity of knee and foot problems were different between morbid obesity (MO) and superobesity (SO), a prospective clinical study was designed.

Methods: Bariatric candidates (N = 81, body mass index 40-81.3 kg/m(2), 43.

Effect of genetic variants related to lipid metabolism as risk factors for cholelithiasis after bariatric surgery in Brazilian population.

Background: The manifestation of cholelithiasis after bariatric surgery may depend on genetic factors related to lipid metabolism, including apolipoprotein E (APOE) and cholesteryl ester transfer protein (CETP) gene polymorphisms.

Methods: We investigated the association between APOE HhaI and CETP TaqIB polymorphisms [PCR-RFLP] and occurrence of cholelithiasis over up to 8 months of follow-up after gastroplasty to Roux-en-Y gastric bypass in 220 patients distributed in Group 1 (G1) 114 with cholelithiasis postoperatively and Group 2 (G2) 106 without cholelithiasis, including biochemical and anthropometric profiles analyses.

Results: In our series, the allelic and genotypic distributions of CETP TaqIB and APOE HhaI polymorphisms were similar in both groups (P > 0.
