AIMS Implantation of single-lead VDD pacemakers is an established alternative to DDD pacing in patients with atrioventricular block. This study compares the long-term costs of both systems. METHODS AND RESULTS Three hundred and sixty patients with atrioventricular block received VDD or DDD pacemakers in alternating order. Primary costs of implantation included: devices, leads and operation ma...

OBJECTIVE To examine the hypothesis that vitamin D deficiency (VDD) is associated with an increased prevalence of microvascular complications in young people with type 1 diabetes. RESEARCH DESIGN AND METHODS In a cross-sectional study of 517 patients, 25-hydroxyvitamin D was measured. Retinopathy was assessed by 7-field stereoscopic retinal photography, peripheral neuropathy by thermal and vi...

OBJECTIVE To review the indications, surgical techniques, and results of vertical lobule division (VLD) of the alar cartilages as they relate to the M-Arch Model. DESIGN Retrospective study of patients who underwent VLD of the lower lateral cartilages at a private facial plastic surgery practice in a major university teaching hospital. RESULTS Vertical lobule division decreased projection i...

Vine decline disease (VDD) constitutes a menace to melons worldwide. Especially, the one caused by fungus Monosporascus cannonballus. Thus, resistant plant material must be released help growers. Hence, our goal was develop VDD. More than 600 melon accessions are expected tested for resistance in M. cannonballus infested soil Weslaco, Texas, USA, identify VDD, and other important traits. So far...

Studies from our center and other parts of India have drawn attention towards wide prevalence of vitamin D deficiency (VDD) in our country. VDD has been reported in all age groups including toddlers, school children, pregnant women and their neonates and adult males and females residing in rural and urban India. We reviewed implications of VDD in our population based on the preliminary data ava...

OBJECTIVE To describe the prevalence of Vitamin D deficiency (VDD) and insufficiency (VDI), and the main dietary sources of vitamin D (VD) in a probabilistic sample of Mexican women at reproductive age participating in Ensanut 2012, stratified by sociodemographic factors and body mass index (BMI) categories. MATERIALS AND METHODS Serum concentrations of 25-hydroxyvitamin-D(25-OH-D) were deter...

The continuing increase in FPGA size and complexity and the emergence of sub-100nm technology have made FPGA power consumption, both dynamic and static, an important design consideration. In this work, we propose a programmable dual-VDD architecture in which the supply voltage of the logic blocks and routing blocks are programmed to reduce power consumption by assigning low-VDD to non-critical ...

OBJECTIVE Recent data suggest vitamin D deficiency (VDD) is associated with bacterial vaginosis (BV) during pregnancy. We hypothesized that VDD is a risk factor for BV in nonpregnant women. STUDY DESIGN Using National Health and Nutrition Examination Survey data, we conducted multivariable logistic regression analyses stratified by pregnancy. RESULTS VDD was associated with BV only in pregn...

BACKGROUND Dual chamber pacemakers (single chamber pacing dual chamber sensing cardiac pacemaker (VDD) and dual chamber pacing and sensing cardiac pacemaker (DDD)) are being used frequently in children and adolescents. The aim of this study was to verify the safety and performance of the VDD and DDD pacing systems, and to evaluate the differences between two pacing modes with regard to atrial s...
