Rational use of short-term anorectic drugs for one-year effective treatment of obesity: An analysis of four studies.

Background: Obesity is a complex disease for which pharmacotherapy is often used. Anti-obesity drugs (AODs) are characterized by inducing a variable inter-subject body weight reduction (BWR), the attainment of a plateau after their maximal effect is achieved, and weight regain after drug discontinuation, which complicate individualized treatment of obesity.

Objective: This exploratory analysis aimed to compare the first-month body weight reduction in kg (1mo-BWRkg) and tolerance development (moT) of four known interventions with low (placebo), intermediate (phentermine or mazindol monotherapy), and high (5 active ingredients fixed-dose combination) efficacy, as predictors of their 6-month body weight reduction efficacy in percent (6mo-BWR%).

Osteoprotegerin Gene Polymorphisms Are Associated with Subclinical Atherosclerosis in the Mexican Mestizo Population.

Subclinical atherosclerosis (SA) is the presence of coronary calcification in the absence of cardiovascular symptoms, and it usually progresses to atherosclerotic disease. Studies have shown an association of osteoprotegerin gene (OPG) variants with calcification process in cardiovascular diseases; however, to this day there are no studies that evaluate individuals in the asymptomatic stage of atherosclerotic disease. Therefore, the purpose of this study was to analyze the association of four genetic variants and haplotypes of the OPG gene with the development of SA, through TaqMan genotyping assays.
