Analysis of variance for repeated measures with Newman-Keuls post-hoc test was used to characterize the effects of IAP and volemia on the circulatory, respiratory and intra-abdominal parameters.
Pearson coefficients were used first to describe inter-correlation between the various body composition and abdominal fat parameters, and then to describe the associations between these parameters and MetS or HOMA-IR.
These abdominal fat parameters were inversely correlated with peritoneal KT/V, creatinine, and nPCR.
We included many of these in our analysis, although they had to be slightly adapted to our situation; abdominal circumference a parameter widely used in ultrasound diagnosis was not measured in this study.
In these subjects, in addition to above mentioned clinical parameters, abdominal visceral and subcutaneous fat area was calculated using computed tomography scans at the level of L4-L5 and percentage body fat was measured by dual-energy X-ray absorptiometry (DEXA).
Furthermore, some of the analyzed obstetric parameters (abdominal tone, uterine tone, engagement of fetal breech) were subjective assessments.
In patients with RA, insulin resistance has been shown to correlate both with anthropometric parameters (abdominal obesity) and high disease activity [ 13, 14].
Response was defined as improvement in a number of clinical parameters (including abdominal pain, diarrhea, rectal bleeding, and cessation of transfusions).
These criteria include a combination of clinical and analytical parameters, mainly abdominal perimeter.
The second group included 28 patients undergoing major abdominal surgery, with negative parameters for systemic inflammatory response syndrome (Table 1).
The fetal parameters were abdominal circumference (AC), biparietal diameter (BPD: the transverse diameter of the head), and femur length (FL).
