- Abstract
Pregnancies complicated by pre-gestational diabetes (PGD) are associated with a higher rate of adverse outcomes, including an increased rage of preterm delivery, pregnancy-induced hypertension, pre-eclampsia, caesarean section, perinatal mortality, stillbirth, shoulder dystocia, macrosomia, small for gestational age, large for gestational age, low birth weight, neonatal hypoglycemia, neonatal death, low Apgar score, NICU admission, jaundice and respiratory distress. In the past two decades, numerous reports have been published regarding associations between PGD and risk of adverse outcomes. However, study results are inconsistent. To provide a synopsis of the current understanding of PGD for risk of adverse pregnancy outcomes, a random-effects meta-analysis over 40 million subjects from 100 studies was performed to calculate the pooled ORs. Potential sources of heterogeneity were systematically explored by multiple strata analyses and meta-regression. Overall, PGD were significantly associated with increased risk of preterm delivery (OR=3.48), LGA (OR=3.90), perinatal mortality (OR=3.39), stillbirth (OR=3.52), pre-eclampsia (OR=3.48), caesarean section (OR=3.52), NICU admission (OR=3.92), and neonatal hypoglycemia (OR=26.62). Significant results were also observed for 7 adverse outcomes with OR range from 1.54 to 2.82, while no association was found for SGA and respiratory distress after Bonferroni correction. We found that women with T1DM had higher risks for most of adverse pregnancy outcomes compared with women with T2DM. When stratified by study design, sample size, type of diabetes, geographic region, and study quality, significant associations remains. Our findings demonstrated that PGD is a strong risk-conferring factor for adverse maternal, perinatal and neonatal outcomes., Competing Interests: CONFLICTS OF INTEREST The authors confirm that this article content has no conflicts of interest.

- Abstract
Background and Objective: Transradial access is an attractive approach for angiography or percutaneous coronary intervention. Different devices have been used to apply pressure locally at the site of arterial entry for achieving hemostasis. The aim of this study was to evaluate the effect of 2 different hemostatic devices on radial artery outcomes after transradial coronary intervention., Subjects and Methods: This study included 600 patients who had undergone transradial coronary intervention who were randomized into 2 groups after the procedure: 300 were treated with a radial compression device (TR Band, Terumo Medical, Tokyo, Japan) (CD group) and the other 300 patients were treated using a chitosan-based pad (Anscare, Daxon, Taoyuan, Taiwan) (CS group). Compression time, major and minor access site bleeding complications, and incidence of radial artery occlusion were recorded., Results: There were no statistical differences in the baseline clinical characteristics of the patients between the 2 groups. Compression time in the CS group was significantly shorter than that in the CD group (P < .001). Although no major access site bleeding complications were observed in either group, 6 patients in each group experienced minor access site bleeding complications. At the same time, 61 patients in the CD group and 21 patients in the CS group experienced errhysis (20% vs 7%, respectively; P < .001). Early radial artery occlusion (24 hours) occurred in 11.7% of the patients in the CD group and 5.4% of the patients in the CS group (P < .05). Chronic radial artery occlusion (30 days) occurred in 10% of the patients in the CD group and 5% of the patients in the CS group (P < .05)., Conclusion: The application of the chitosan-based pad showed better hemostatic efficacy and a lower incidence of radial artery occlusion after transradial coronary intervention compared with the compression device.

- Abstract
Blood pressure (BP) remains poorly controlled among hypertensive patients with coronary heart disease (CHD) in China. Improvement of its management will require an understanding of the patient characteristics and treatment factors associated with uncontrolled hypertension. A cross-sectional survey of 3,279 patients from 52 centers in China was performed to examine potential barriers to adequate blood pressure control of hypertensive patients with CHD. Uncontrolled hypertension was defined as blood pressure ≥130/or 80 mmHg. Multivariable logistic regression was used to identify factors associated with poor blood pressure control. Mean age of the patients was 65 years, 40% were women, and mean BMI was 25 kg/m(2). Mean systolic blood pressure was 136±18 mmHg and mean diastolic blood pressure was 80±11 mmHg. Only 18% of patients had a mean blood pressure <130/80 mmHg during the study period. Multivariate analysis revealed several independent factors of poor blood pressure control: body mass index ≥23 kg/m(2), the presence of stable angina pectoris (SAP), family history of diabetes, and use of calcium channel blockers (CCB). Further analysis showed that non-dihydropyridine calcium antagonist was significantly correlated with low BP control rate. Some of these may be amenable to modification. The results of our study suggest that overweight, the presence of SAP and family history of diabetes are important factors for tight BP control in primary care. In addition, non-dihydropyridine calcium channel blockers appear less effective than other therapies in control of blood pressure and should not be the first choice among hypertensive patients with CHD. Further identification of patients at risk of poor BP control can lead to targeted interventions to improve management.

- Abstract
Background: Vaspin was a recently identified adipokine, playing a protective role in many metabolic diseases. The present study aimed to investigate the association between vaspin plasma level and stable angina pectoris (SAP) and unstable angina pectoris (UAP)., Methods: A total of 88 patients with angiographically-proved coronary artery disease (CAD) (SAP 47, UAP 41) and 103 control subjects without cardiovascular diseases were enrolled in this study. Circulating vaspin, mRNA expression of vaspin in peripheral blood mononuclear cells (PBMC), clinical parameters, lipid profile and high-sensitivity C-reactive protein (hsCRP) were assayed. The severity of CAD was also assessed according to the number of vessels diseased., Results: There are significant differences in circulating vaspin levels and mRNA levels of PBMC between SAP and UAP groups (SAP 0.91±0.95 ng/mL and UAP 0.43±0.38 ng/mL, p<0.01 in circulating vaspin level; SAP 1.19±0.85 and UAP 0.82±0.56, p<0.05 in mRNA level of PBMC). An inverse correlation between the number of diseased vessels and plasma vaspin concentration was observed (r=-0.350, p<0.01) in the CAD group. Construction of receiver operating characteristic curves confirmed that vaspin plasma concentrations significantly differentiated CAD patients (area under the curve=0.684, p<0.001), as well as UAP (area under the curve=0.640, p<0.05)., Conclusion: Decreased vaspin plasma levels and mRNA levels in PBMC were observed in patients with UAP. Low vaspin concentrations correlate with CAD severity. The findings suggested that vaspin could serve as a novel biomarker of CAD as well as UAP.

- Abstract
A bathymetric lidar survey is the most cost efficient method of producing bathymetric maps in near shore areas where the ocean bottom is both highly variable and of greatest importance for shipping and recreation. So far, not much attention has been paid to the influence of bottom materials on the lidar signals. This study addresses this issue using a Monte Carlo modeling technique. The Monte Carlo simulation includes a plane parallel water body and a flat bottom with or without seagrass. The seagrass canopy structure is adopted from Zimmerman (2003). Both the surface of the seagrass leaves and the bottom are assumed to be Lambertian. Convolution with the lidar pulse function followed by the median operator is used to reduce the variance of the resultant lidar waveform. Two seagrass orientation arrangements are modeled: seagrass in still water with random leaf orientation and seagrass with a uniform orientation as would be expected when under the influence of a water current. For each case, two maximum canopy heights, 0.5 m and 1 m, three shoot densities, 100, 500, and 1000, and three bending angles, 5, 25, and 45 degrees, are considered. The seagrass is found to induce a depth bias that is proportional to an effective leaf area index (eLAI) and the contrast in reflectance between the seagrass and the bottom material., (© 2011 Optical Society of America)

- Abstract
This article introduces a novel method named "Parallel Imaging and Noquist in Tandem" (PINOT) for accelerated image acquisition of cine cardiac magnetic resonance imaging. This method combines two prior information formalisms, the SPACE-RIP implementation of parallel imaging and the Noquist method for reduced-data image reconstruction with prior knowledge of static and dynamic regions in the field of view. The general theory is presented, and supported by results from experiments using time-resolved two-dimensional simulation data and retrospectively sub-sampled magnetic resonance imaging data with acceleration factors around 4. A signal-to-noise ratio analysis and a comparison study with TSENSE and k-t SENSE show that PINOT performs favorably in preserving edge detail, at a cost in signal-to-noise ratio and computational complexity., (Copyright © 2010 Wiley-Liss, Inc.)
