BACKGROUND: This study evaluates the presence of metabolic syndrome (MS) and its association with C-reactive protein (CRP) and other cardiovascular (CV) risk factors, in a sample of women with and without previous Gestational Diabetes (pGDM). METHODS: One hundred and sixty-six women with pGDM and 98 women (controls) with uncomplicated pregnancy were studied 16 months after delivery. In all women, plasma glucose, insulin, lipid profile, serum uric acid, C-reactive protein, fibrinogen and homocysteine were measured. MS was defined according to NCEP ATPIII criteria. RESULTS: MS was identified in 15 pGDM women (9%) versus 1 control (1%) (p < 0.001). The more frequent metabolic traits were abdominal obesity (36% vs 17%) and low HDL-cholesterol (34% vs 17% in pGDM women and controls, respectively; all p < 0.01). HOMA-R, LDL-cholesterol, fibrinogen, serum uric acid and CRP resulted significantly higher in pGDM women with MS as compared to those without MS after adjustment for BMI. In women with no criteria for MS, only CRP levels were found to be higher in pGDM women compared to controls (p < 0.05). Seventeen percent of pGDM women with no criteria for MS had CRP levels >or=1 mg/L (all controls showed CRP levels <1 mg/L). After a stepwise regression analysis, CRP levels were independently correlated to HOMA-R (r2 = 0.27, p < 0.001) and fibrinogen (r2 = 0.30, p < 0.001). CONCLUSIONS: In our population, MS occurs in a sizable proportion of pGDM women and is associated with increased levels of CRP, fibrinogen, uric acid and LDL-cholesterol. Moreover, higher levels of CRP, a marker of chronic low-grade inflammation, are present in a subset of women with pGDM, independently of MS.
The aim of this study was to prepare nonwoven materials from poly(epsilon-caprolactone) (PCL) and their antibiotic containing forms by electrospinning, so as to prevent postsurgery induced abdominal adhesions in rats. epsilon-Caprolactone was first polymerized by ring-opening polymerization, and then it was processed into matrices composed of nanofibers by electrospinning. A model antibiotic (Biteral) was embedded within a group of PCL membranes. In the rat model, defects on the abdominal walls in the peritoneum were made to induce adhesion. The plain or antibiotic embedded PCL membranes were implanted on the right side of the abdominal wall. No membrane implantation was made on the left side of the abdominal wall that served as control. Macroscopical and histological evaluations showed that using these barriers reduces the extent, type, and tenacity of adhesion. The antibiotic embedded membranes significantly eliminated postsurgery abdominal adhesions, and also improved healing.
BACKGROUND AND OBJECTIVES: We examined the effects of pulse energy variations on the dimensions of microscopic thermal injury zones (MTZs) created on human skin ex vivo and in vivo using nonablative fractional resurfacing. MATERIALS AND METHODS: A Fraxel SR laser system emitting at 1,550 nm provided an array of microscopic spots at variable densities. Pulse energies ranging from 4.5 to 40 mJ were tested on human abdominal skin ex vivo and in vivo. Tissue sections were stained with hematoxylin and eosin (H&E) or nitro blue tetrazolium chloride (NBTC) and MTZ dimensions were determined. Ex vivo and in vivo results were compared. Dosimetry analyses were made for the surface treatment coverage calculation as a function of pulse energy and collagen coagulation based on H&E stain or cell necrotic zone based on NBTC stain. RESULTS: Each MTZ was identified by histological detection of a distinct region of loss of tissue birefringence and hyalinization, representing collagen denaturation and cell necrosis within the irradiated field immediately, 1, 3, and 7 days after treatment. At high pulse energies, the MTZ depth could exceed 1 mm and width approached 200 microm as assessed by H&E. NBTC staining revealed viable interlesional tissue. In general, no statistically significant difference was found between in vivo and ex vivo depth and width measurements. CONCLUSIONS: The Fraxel SR laser system delivers pulses across a wide range of density and energy levels. We determined that increases in pulse energy led to increases in MTZ depth and width without compromising the structure or viability of interlesional tissue.
