PP-205: CARDIAC INVOLVEMENT IN GLYCOGEN STORAGE DISEASE TYPE IV: TWO CASES AND THE TWO ENDS OF A SPECTRUM
No full textDynamic cardiomyoplasty: impact of effective pacing
No full textDynamic cardiomyoplasty, in which the transposed latissimus dorsi muscle is wrapped around the heart and then electrically stimulated to augment systolic dysfunction, is an alternative surgical treatment for severe cardiomyopathies. Critical to success of this operation is to provide the wrapped skeletal muscle with more fatigue-resistant structure through repetitive electrical stimulation. A cardiostimulating device is important in this regard to perform synchronised contraction contributing to symptomatic improvement. Here in, we present a case with dynamic cardiomyoplasty improving following renewal of impaired myostimulator device. (C) 2003 Elsevier Ireland Ltd. All rights reserved
Preserved systolic function with isolated left ventricular noncompaction in an elderly patient
No full textRelationship between CHA2DS2-VASc and CHADS2 Scores with Pulmonary Hypertension in Patients with Acute Pulmonary Embolism
No full textIntroduction: Pulmonary hypertension (PH) is the most important prognostic factor after acute pulmonary embolism (PE). Therefore, determination of patients who will develop PH after acute PE is crucial. The aim of the present study was to evaluate the predictive value of the CHADS2 and CHA2DS2-VASc scores for PH in patients with acute PE. Material and methods: Seventy-nine adults who presented with acute PE, had an admission systolic pulmonary artery pressure (sPAP) measured on echocardiogram and no previous history of PE, were retrospectively identified from the computerized database. 31 patients who had sPAP ≤ 40 mm Hg were categorized as a “normal pulmonary pressure” group, whereas 48 patients who had sPAP > 40 mm Hg were categorized as a “PH” group. Results: SPAP was > 40 mm Hg in 48 patients (60.8%), with a mean sPAP of 60.9 ± 16.1 mm Hg (median = 60, min–max = 41–100 mm Hg). In multivariate logistic regression models adjusted for CHADS2 and CHA2DS2-VASc score components, only age was found to be related with the development of PH. SPAP was weakly positively correlated with CHADS2 (p = 0.047; r = 0.224) and CHA2DS2-VASc (p = 0.023; r = 0.256) scores. SPAP values were increasing with the severity of the scores. Conclusions: Both CHADS2 and CHA2DS2-VASc scores could be useful in the determination of which patients should be closely followed up in order to prevent the development of PH after acute PE

No full textAssessing forest fire behavior simulation using FlamMap software and remote sensing techniques in Western Black Sea Region, Turkey
No full textAim of study: Forest fuels are very critical for fire behavior models and hazard maps. Relationship among wind speed, fuel moisture content, slope, and fuel type directs us to predict fire behavior of a given region. For this study, we evaluated fire behavior parameters such as fireline intensity and rate of fire spread using the fuel moisture content, slope, fuel load, and wind speed for the Bayam Forest District with the help of remote sensing techniques and FlamMap software.Area of study: The study area is located in Bayam Forest District in the city of Taskopru, Kastamonu, a Western Black Sea region of Turkey.Material and Methods: In order to estimate and map forest fuel load of the study area, fuel models were developed using the parameters of the average vegetation height, 1-hr, 10-hr, and 100-hr fuel load, foliage, total fuel load, litter load and litter depth. Three basic fire descriptors (fireline intensity, rate of fire spread, and flame length) were calculated using FlamMap software with the parameters fuel load, wind speed, fuel moisture, and slope. Using the descriptors above, the historical fire data was overlaid with the fireline intensity maps to determine fire potential areas within the remote sensing and GIS framework.Main results: The results of this study showed that 20.0% of the region had low (<2 m min-1), 43.2% had moderate (2-15 m min-1), 12.0% had high (15-30 m min-1), and 24.8% had very high (>30 m min-1) rate of fire spread, respectively. The fireline intensity map showed that 60.7% of the area was in low (0-350 kW m-1), 24.9% was in moderate (350-1700 kW m-1), 1.3% was in high (1700-3500 kW m-1), and 13.0% was in very high (>3500 kW m-1) fireline intensity.Highlights: The spatial extent of fuel types was observed and three of the potential fire behavior predictors (fire intensity, rate of fire spread and flame length) were estimated using remote sensing and GIS techniques. The overlaid historical fire data showed that the most fire-prone areas are in the mixed young Anatolian black pine - Scots pine tree stands that have 40-70% canopy cover and that are in the young Anatolian black pine tree stands that have more than 70% canopy cover
