| 1 | Catheter ablation of atrial fibrillation in elderly population显示文摘Background Although elderly patients have been included in published series of catheter ablation for atrial fibrillation (AF), clinicalbenefit and safety remain still less defined in this population. A retrospective analysis of the results of catheter ablation for AF in a large volumecenter focused on comparison of elderly patients with the rest of the patient cohort was conducted in this study. Methods Consecutive patientswho underwent catheter ablation for AF between January 2001 and December 2016 were analysed. A total population of 3197 patients wasdichotomized by the age of 70 years (394 elderly vs. 2803 younger subjects). Patients were followed in terms of arrhythmia status and sur-vival for a median period of 18 vs. 21 and 35 vs. 57 months, respectively. Results Elderly patients were more frequently females (49% vs.29%, P 〈 0.0001), had a history of hypertension (79% vs. 57%, P 〈 0.0001), diabetes (16% vs. 11%, P 〈 0.01), stroke (9% vs. 6%, P 〈 0.01),coronary/peripheral artery disease (14% vs. 8%, P 〈 0.0001), and CHAzDS2-VASc score (3.1 ± 1.3 vs. 1.5 ± 1.2 s, P 〈 0.0001). Major com-plications were more frequent in elderly (5.3% vs. 3.2%, P = 0.03); however, this difference was driven by vascular complications (3.6% vs.1.9%, P = 0.04). There were comparable rates of cerebrovascular (0.3 vs. 0.3%) or nonvascular complications (1.8 vs. 1.2%). Good arrhyth-mia control was inferior in elderly patients as compared with the rest of the cohort, both without and with antiarrhythmic drugs: 44.2% vs.58.2% (P 〈 0.0001) and 78.2 vs. 83.2% (P 〈 0.01), respectively. Poor arrhythmia control was associated with relative risk of all-cause mor-tality of 2.7 (95% CI: 1.1-6.4) in elderly patients and 1.4 (95% CI: 0.9-2.0) in younger subjects. Conclusions Catheter ablation for AF inelderly patients is safe although somewhat less effective. Good arrhythmia control is associated with better survival, especially in elderly patients. | Josef Kautzner Petr Peichl Marek Sramko Robert Cihak Bashar Aldhoon Dan Wichterle | 2017 | Journal of Geriatric Cardiology2017，14，9： | 9 |
| 2 | Divergent apparent temperature sensitivity of terrestrial ecosystem respiration显示文摘Aims Recent studies revealed convergent temperature sensitivity of ecosys-tem respiration(Re)within aquatic ecosystems and between terrestrial and aquatic ecosystems.We do not know yet whether various terres-trial ecosystems have consistent or divergent temperature sensitivity.Here,we synthesized 163 eddy covariance flux sites across the world and examined the global variation of the apparent activation energy(Ea),which characterizes the apparent temperature sensitivity of and its interannual variability(IAV)as well as their controlling factors.Methods We used carbon fluxes and meteorological data across FLUXNET sites to calculate mean annual temperature,tempera-ture range,precipitation,global radiation,potential radiation,gross primary productivity and Re by averaging the daily values over the years in each site.Furthermore,we analyzed the sites with>8 years data to examine the IAV of Ea and calculated the standard deviation of Ea across years at each site to character-ize IAV.Important Findings The results showed a widely global variation of Ea,with significantly lower values in the tropical and subtropical areas than in temperate and boreal areas,and significantly higher values in grasslands and wetlands than that in deciduous broadleaf forests and evergreen for-ests.Globally,spatial variations of Ea were explained by changes in temperature and an index of water availability with differing contribution of each explaining variable among climate zones and biomes.IAV and the corresponding coefficient of variation of Ea decreased with increasing latitude,but increased with radiation and corresponding mean annual temperature.The revealed patterns in the spatial and temporal variations of Ea and its controlling factors indicate divergent temperature sensitivity of Re,which could help to improve our predictive understanding of Re in response to climate change. | Bing Song Shuli Niu Ruisen Luo Yiqi Luo Jiquan Chen Guirui Yu Janusz Olejnik Georg Wohlfahrt Gerard Kiely Asko Noormets Leonardo Montagnani Alessandro Cescatti Vincenzo Magliulo Beverly Elizabeth Law Magnus Lund Andrej Varlagin Antonio Raschi Matthias Peichl Mats BNilsson Lutz Merbold | 2014 | Journal of Plant Ecology2014，7，5： | 2 |
