We conducted a retrospective analysis of prospectively collected data in MO women undergoing BS between 2006 and 2010. Anthropometric, metabolic comorbidities, and inflammatory markers were compared at baseline and 12 months after BS, between 52 women (10.4 %) presenting with a HOMA-IR < 2.94 (80th percentile reference population) (IS-MO group) and an age- and BMI-matched group of women (n = 52) with HOMA-IR > 2.94.
The IS-MO women presented a more favorable metabolic and inflammatory profile as compared to the IR-MO group. However,
an enlarged waist circumference (WC), a high-sensitivity C-reactive protein (hs-CRP) > 3 mg/dL, and metabolic syndrome (MS) were present in 100 %, 90 %, selleckchem and 51.9 % of the IS-MO group at baseline. At 12 months after surgery, all the MS components and hs-CRP improved in IS-MO subjects (p < 0.01). The prevalence of the MS in the IS-MO group significantly decreased (11 %, p < 0.05) despite WC and hs-CRP being abnormal respectively in 53.3 % and 20.0 % of women in this group.
In MO women, an IS in the normal range is associated with a limited protection from metabolic co-morbidities. Nonetheless, BS results in the amelioration of the altered metabolic and inflammatory profiles YM155 inhibitor also in this group of subjects.”
“Background: Cardiovascular
magnetic resonance (CMR) T1 mapping indices, such as T1 time and partition coefficient (lambda), have shown potential to assess diffuse myocardial fibrosis. The purpose of this study was to investigate how scanner and field strength variation affect the accuracy and precision/reproducibility
of T1 mapping indices.
Methods: CMR studies were performed on two 1.5T and three 3T scanners. Eight phantoms were made to mimic the T1/T2 of pre- and post-contrast myocardium and blood at 1.5T and 3T. T1 mapping using MOLLI was performed with simulated heart rate of 40-100 bpm. Inversion recovery spin echo (IR-SE) was the reference standard for T1 determination. Accuracy was defined as the percent error between MOLLI and IR-SE, and scan/re-scan reproducibility was defined as the relative percent mean difference between repeat MOLLI scans. Partition coefficient was estimated by Delta R1myocardium phantom/Delta GSK126 chemical structure R1blood phantom. Generalized linear mixed model was used to compare the accuracy and precision/reproducibility of T1 and lambda across field strength, scanners, and protocols.
Results: Field strength significantly affected MOLLI T1 accuracy (6.3% error for 1.5T vs. 10.8% error for 3T, p<0.001) but not lambda accuracy (8.8% error for 1.5T vs. 8.0% error for 3T, p=0.11). Partition coefficients of MOLLI were not different between two 1.5T scanners (47.2% vs. 47.9%, p=0.13), and showed only slight variation across three 3T scanners (49.2% vs. 49.8% vs. 49.9%, p=0.016). Partition coefficient also had significantly lower percent error for precision (better scan/re-scan reproducibility) than measurement of individual T1 values (3.
