First, although we started the calibration procedure at a low speed to account for the high metabolic cost of walking in this group of severely obese subjects, 14 subjects spend more than three METs at two km/h.
In a country otherwise known for Bangkok's chaos and an almost-anything-goes tourist industry, Thailand's royal family is a severely protected subject.
We found a markedly lower prevalence of MetS as compared to the study by Weiss et al, in children of comparable age, who described a prevalence of 38.7% (moderately obese subjects) to 49.7% (severely obese subjects), applying the same definition [ 13].
The objective of this study was to investigate readily available circulating biomarkers of ECS activation in severely obese subjects compared to normal weight subjects by combining accurate measurement of plasma endocannabinoid levels with SNP genotyping in critical ECS inactivating enzymes.
In this study, the FAAH 385 C→A (P129T) mutant genotype, which is the principal catabolic enzyme of many N-acyl ethanolamine ECS signaling molecules, has the same approximately 2-fold prevalence (7.3% vs. 4%) in severely obese subjects compared to normal BMI subjects observed in a previous study (28).
As observed in the laboratory, the attachment of the accelerometers can be more challenging for severely obese subjects than for normal-weight subjects, and tilting of the instrument is known to reduce the level of counts [ 10].
Therefore, an association detected in a study with mildly affected subjects may not be supported in studies with severely affected subjects, and an association detected in a study with severely affected subjects may not be supported in studies with mildly affected subjects.
Clinical data and blood were collected from 40 severely obese subjects (BMI>40 kg/m2) and 20 lean healthy subjects.
Among neutropenic subjects, the numbers of mildly, moderately and severely neutropenic subjects were found to be higher in the study group (p < 0.05).
The distinction between the physiology of sedentary compared with modestly, vigorously physically active subjects and between normoglycaemic and modestly or severely hypoglycaemic subjects emphasizes a danger of generalization beyond the scope of a paradigm: incorrect conclusions can be drawn.
