“The objective of the study was to evaluate the accuracy of established prediction equations that calculate resting energy expenditure (REE) in obese women. This was a cross-sectional study. In 273 mildly to severely obese women (age, 41.7 +/- 13.2 years; body mass index, 42.8 +/- 7.0 kg/m(2)), REE was measured by indirect calorimetry (mREE), along with PHA-848125 clinical trial fat mass (FM) and fat-free mass (FFM) by bioelectrical impedance analysis. Eleven established equations were

used to predict REE (pREE), with 9 equations basing on the anthropometric parameters body weight and height and 2 equations including body composition parameters (FM, FFM). All equations provided pREE values that significantly correlated with mREE (r > 0.66, P < .001), although 8 equations systematically underestimated mREE (P

< .05). Of note, even the best equation was not able to accurately predict mREE with a deviation of less than +/- 10% in more than 70% of the tested women. Furthermore, equations using body composition data were not superior in predicting REE as compared with equations exclusively including anthropometric variables. Multiple linear regression analyses revealed 2 new equations-one including body weight and age and another including FM, FFM, and age-that explained 56.9% and 57.2%, respectively, of variance in mREE. However, when these 2 new equations were applied to an independent sample of 33 obese women, they also provided an accurate prediction ( 10%) of mREE in only 56.7% and 60.6%, respectively, of the women. Data show that an accurate prediction of REE is not feasible MK-2206 molecular weight using established equations in obese

women. Equations that include body composition parameters as assessed by bioelectrical impedance analysis do not increase the accuracy of prediction. Based on our results, we conclude P505-15 nmr that calculating REE by standard prediction equations does not represent a reliable alternative to indirect calorimetry for the assessment of REE in obese women.

“A 72-year-old man developed a generalized erythematous pustular eruption 11 weeks after commencing terbinafine. Clinically and histologically, the appearance was that of acute generalized exanthematous pustulosis (AGEP), and the disease was managed with topical preparations. Initial improvement was marred by relapse of acute pustulosis, now more in keeping with terbinafine-induced pustular psoriasis (PP), which was successfully treated with acitretin. This case highlights the difficulty of differentiating between AGEP and PP.”
“Aim: Oxidative stress is stated to be an important mechanism of cold immobilization stress leading to tissue injury. The aim of this study was to investigate the effects of exogenous leptin administration on plasma and hepatic tissue lipid peroxidation and antioxidant status in cold-restraint stress.
