2A study of local amplification effect of soil layers on ground motion in the Kathmandu Valley using microtremor analysis显示文摘Past researchers have anticipated the occurrence of a great earthquake in the central Himalayas in the near future.This may cause serious damage in the Kathmandu Valley,which sits on an ancient lake bed zone,with lacustrine sediments of more than 500 m depth.In this study,the predominant frequency of ground motion is evaluated using the Horizontal-to-Vertical(H/V) spectral ratio technique and recordings of ambient noise.The results of the H/V ratio show two peaks in about 20 percent of the locations,which are distributed mainly in and around the center and northern part of the Kathmandu Valley.The predominant frequencies vary from 0.5 Hz to 8.9 Hz in the study area,whereas the second resonance frequency varies from 4 Hz to 6 Hz in the center and northern part of the valley.This indicates that the center and northern part of the valley have a wide range of resonance frequency due to two levels of impedance contrast one may be from the surface layer and the other may be from the layer underneath.These two levels of resonance indicate the importance of considering the effects of surface and lower layers during the planning and designing of infrastructures in the Kathmandu Valley.Paudyal Y.R.

4Who benefits from percutaneous closure of patent foramen ovale vs medical therapy for stroke prevention? In-depth and updated metaanalysis of randomized trials显示文摘BACKGROUND A few randomized clinical trials(RCT) and their meta-analyses have found patent foramen ovale closure(PFOC) to be beneficial in prevention of stroke compared to medical therapy. Whether the benefit is extended across all groups of patients remains unclear.AIM To evaluate the efficacy and safety of PFOC vs medical therapy in different groups of patients presenting with stroke, we performed this meta-analysis of RCTs.METHODS Electronic search of PubMed, EMBASE, Cochrane Central, CINAHL and ProQuest Central and manual search were performed from inception through September 2018 for RCTs. Ischemic stroke(IS), transient ischemic attack(TIA), a composite of IS, TIA and systemic embolism(SE), mortality, major bleeding,atrial fibrillation(AF) and procedural complications were the major outcomes.Random-effects model was used to perform analyses.RESULTS Meta-analysis of 6 RCTs including 3560 patients showed that the PFOC,compared to medical therapy reduced the risk of IS [odds ratio: 0.34; 95%confidence interval: 0.15-0.78; P = 0.01] and the composite of IS, TIA and SE [0.55(0.32-0.93); P = 0.02] and increased the AF risk [4.79(2.35-9.77); P < 0.0001]. No statistical difference was observed in the risk of TIA [0.86(0.54-1.38); P = 0.54],mortality [0.74(0.28-1.93); P = 0.53] and major bleeding [0.81(0.42-1.56); P = 0.53]between two strategies. Subgroup analyses showed that compared to medical therapy, PFOC reduced the risk of stroke in persons who were males, ≤ 45 years of age and had large shunt or atrial septal aneurysm.CONCLUSION In certain groups of patients presenting with stroke, PFOC is beneficial in preventing future stroke compared to medical therapy.Khagendra Dahal Adil Yousuf Hussam Watti Brannen Liang Sharan Sharma Jharendra Rijal Pavan Katikaneni Kalgi Modi Neeraj TANDon Michael Azrin Juyong Lee 2019World Journal of Cardiology2019,11,4:4

8An Investigation of Landslide Susceptibility Using Logistic Regression and Statistical Index Methods in Dailekh District, Nepal显示文摘Landslide distribution and susceptibility mapping are the fundamental steps for landslide-related hazard and disaster risk management activities, especially in the Himalaya region which has resulted in a great deal of death and damage to property. To better understand the landslide condition in the Nepal Himalaya, we carried out an investigation on the landslide distribution and susceptibility using the landslide inventory data and 12 different contributing factors in the Dailekh district, Western Nepal. Based on the evaluation of the frequency distribution of the landslide, the relationship between the landslide and the various contributing factors was determined.Then, the landslide susceptibility was calculated using logistic regression and statistical index methods along with different topographic(slope, aspect, relative relief, plan curvature, altitude, topographic wetness index) and non-topographic factors(distance from river, normalized difference vegetation index(NDVI), distance from road, precipitation, land use and land cover, and geology), and 470(70%) of total 658 landslides. The receiver operating characteristic(ROC) curve analysis using 198(30%) of total landslides showed that the prediction curve rates(area under the curve, AUC) values for two methods(logistic regression and statistical index) were 0.826, and 0.823with success rates of 0.793, and 0.811, respectively. The values of R-Index for the logistic regression and statistical index methods were83.66 and 88.54, respectively, consisting of high susceptible hazard classes. In general, this research concluded that the cohesive and coherent natural interplay of topographic and non-topographic factors strongly affects landslide occurrence, distribution, and susceptibility condition in the Nepal Himalaya region. Furthermore, the reliability of these two methods is verified for landslide susceptibility mapping in Nepal’s central mountain region.DIL Kumar RAI XIONG Donghong ZHAO Wei ZHAO Dongmei ZHANG Baojun NIRMAL Mani DAHAL WU Yanhong MUHAMMAD Aslam BAIG 2022Chinese Geographical Science2022,32,5:2
9Coronary vasospasm:A narrative review显示文摘Coronary artery vasospasm(CAVS)plays an important role in acute chest pain syndrome caused by transient and partial or complete occlusion of the coronary arteries.Pathophysiology of the disease remains incompletely understood,with autonomic and endothelial dysfunction thought to play an important role.Due to the dynamic nature of the disease,its exact prevalence is not entirely clear but is found to be more prevalent in East Asian and female population.Cigarette smoking remains a prominent risk factor,although CAVS does not follow traditional coronary artery disease risk factors.Many triggers continue to be identified,with recent findings identifying chemotherapeutics,allergens,and inflammatory mediators as playing some role in the exacerbation of CAVS.Provocative testing with direct visualization is currently the gold-standard for diagnosis,but non-invasive tests,including the use of biomarkers,are being increasingly studied to aid in the diagnosis.Treatment of the CAVS is an area of active research.Apart from risk factor modification,calcium channel blockers are currently the first line treatment,with nitrates playing an important adjunct role.High-risk patients with life-threatening complications should be considered for implantable cardioverter defibrillator(ICD),although timing criteria for escalated therapy require further investigation.The role of pharmaceuticals targeting oxidative stress remains incompletely understood.Jacob Jewulski Sumesh Khanal Khagendra Dahal 2021World Journal of Cardiology2021,13,9:2
