Daptomycin pharmacokinetics were studied in adult volunteers who were moderately obese (body mass index [BMI] = 25-39.9 kg/m2) or morbidly obese (BMI > or =40 kg/m2) and a matched (gender, age, renal function) nonobese (BMI between 18.5 and 24.9 kg/m2) control group. All subjects received a dose of 4 mg/kg total body weight (TBW) by intravenous infusion (30 minutes). Daptomycin plasma half-life, the fraction of the dose excreted unchanged in urine, and daptomycin absolute renal clearance (mL/h) were unchanged as a function of obesity. The absolute volume of distribution (Vz and Vss) and plasma clearance (CL) for daptomycin were higher in obese subjects as compared to nonobese matched controls. The rate of change of Vz and CL with increasing BMI was greater when these pharmacokinetic parameters were expressed in absolute terms compared to when they were normalized for TBW or ideal body weight. This suggests that increases in body mass associated with obesity are proportionality higher than the corresponding increases in Vd and CL. Exposure to daptomycin in obese subjects (Cmax, AUC) was increased 25% and 30%, respectively, compared to nonobese matched controls, well within the range that was previously determined to be safe and well tolerated. Daptomycin may be dosed based on total body weight, and no adjustment in daptomycin dose or dose regimen should be required based solely on obesity.

Failure to thrive is a general term describing infants who do not reach weight, length, or body mass index expected for their age. It can be related often to malnutrition due to inadequate caloric and protein intake, but also to excessive loss of nutrients, inadequate metabolism, inadequate absorption, or excessive caloric and energy expenditure. It may be either organic or inorganic in origin, and in most cases, does not require investigation through complementary examinations.

Genome-wide association studies (GWAS) are often performed on ratios composed of a numerator trait divided by a denominator trait. Examples include body mass index (BMI) and the waist-to-hip ratio, among many others. Explicitly or implicitly, the goal of forming the ratio is typically to adjust for an association between the numerator and denominator.

Phenolic acid-rich fraction from Anisopus mannii (PhAM) contains abundance of ferulic acid, gallic acid, protocatechuic acid, and syringic acid. Among other glycolytic enzymes, in vitro, PhAM counteracted the binding of sodium orthovanadate to phosphofructokinase 1 (PFK-1), improving its activities. In a rat model of diet-induced diabetes, PhAM monotherapy reduced HbA1c by an average of 0.
