Its accuracy to predict fat mass (FM) in obesity and the change in FM following weight loss is questioned. Our objective was to compare leg-to-leg BIA to dual-energy X-ray absorptiometry (DXA) in the assessment of FM in a large population, the changes in FM after Roux-en-Y gastric GSK1210151A cost bypass (RYGB) and to estimate between-method differences (bias) and limits of agreement.

BIA (Tanita BC-420MA) and DXA (Hologic Discovery W) were used in 5,740 consecutive patients (mean BMI, 37.7 +/- 8.2 kg/m(2)) examined in a clinical nutrition department and in 72 women undergoing RYGB (BMI, 47.2 +/- 7.2 kg/m(2)). Analyses

included correlations between methods and Bland Altman analysis.

In the entire population, BIA significantly overestimated FM in comparison Selleckchem MAPK inhibitor with DXA (1.1 +/- 6.1 kg, 0.8 +/- 5.6%). FM estimates by each method were significantly correlated in absolute value (kg; r (2) = 0.9 in the whole population), and in percentage (r (2) = 0.6). However, wide limits of agreement were observed. In surgery patients, BIA significantly overestimated FM both before and

12 months after bypass. BIA significantly overestimated changes in FM after RYGB at 3 months (2.9 +/- 5.0 kg) and at 12 months (1.9 +/- 3.9 kg) but not at 6 months (0.9 +/- 5.0 kg; p = 0.08). Estimates of changes in FM by each method were significantly correlated (r (2) = 0.4, 0.6, and 0.9, respectively).

According to the wide limits of agreement, BIA seems more interesting for epidemiological rather than individual use to evaluate body FM and FM changes in obese women undergoing RYGB.”
“Objective: Pain reduction has been the subject of continuous research in the field

of oral and maxillofacial surgery since postoperative pain with ranging of intensity and duration may affects the patient submitted in an oral surgical procedure. The aim of present study was to compare the analgesic effectiveness between two different anesthetic solutions (articaine and lidocaine) in third molar surgery.

Study Design: A prospective, p38 MAPK activity randomized and clinical study with patients submitted to third molar surgery at two distinct times. The visual analogue scale, the McGill Pain Questionnaire and the analgesic consumption record were used to measure the pain after each surgical time.

Results: Duration of surgery, latency, the amount of anesthetic used and analgesic consumption showed clinical differences with highlights of articaine, though statistical significance was not observed (P < 0.05). The pain scores indicated similar anesthetic efficacy with both solutions.

Conclusion: In the present study no significant differences were observed between lidocaine and articaine in the control of postoperative pain.
