ABSTRACT
Obesity is a complex chronic disease and requires a long-term multimodal approach. The current treatment algorithm for treatment of obesity mainly consists of a stepwise approach, which starts with a lifestyle intervention followed by or combined with medication treatment, whereas bariatric surgery is often reserved for the last option. This article provides an overview of the currently available conservative medicinal treatment regimens and the currently approved medications as well as medications currently undergoing approval studies with respect to the efficacy and possible side effects. Special attention is paid to the importance of combination treatment of pharmacotherapy and surgery in the sense of a multimodal treatment. The data so far show that using a multimodal approach an improvement in the long-term weight loss and metabolic benefits can be achieved for the patients.

Background The measurement of cardiac troponin is central for the diagnosis of myocardial infarction (MI). It is recommended that a coefficient of variation of ≤10% is achieved at the diagnostic threshold and significant change between serial measurements reported. Many modern laboratories use multiple analysers linked by automation where samples are randomly assigned to an analyser. It is therefore important to consider the combined effect of all analysers on the analytical performance of troponin measurement. Method The performance of a contemporary troponin-I (cTn-I) assay run on three analysers, linked by an automated track, was undertaken across a range of cTn-I concentrations. The data for the three analysers were aggregated to obtain the combined analytical coefficient of variation (CVA) and reference change values (RCVs). Results The CVA improved with increasing concentration and calculated RCVs ranged from 67.2% (±13 ng/L) to 32% (±160 ng/L) between cTn-I values 20 ng/L and 500 ng/L. Although there were significant differences in cTn-I measurement between analysers around the diagnostic threshold ( P < 0.05), the CVA was 13.6%. Conclusions We demonstrate that there are significant differences between the performances of analysers which can impact the biochemical criteria for the diagnosis of MI. We also show that the RCV varies according to baseline cTn-I values and that reporting a single RCV across the analytical range of cTn-I may not be appropriate.
