Although potassium is critical for normal electro physiology, the associations between pre-operative serum potassium level
and peri-operative adverse events such as arrhythmias in cardiac surgery have not been examined in detail.
The objective of this study was to determine the prevalence of abnormal pre-operative serum potassium levels and whether such
levels were associated with adverse peri-operative events in 50 patients undergoing coronary artery bypass grafting. Intra-operative
and post-operative arrhythmias, the need for cardio-pulmonary resuscitation, cardiac death and death due to any cause prior
to discharge from the post-operative intensive care unit were studied. The incidence for adverse outcome was 0.5% for death,
0.5% for cardiac death and 2% for cardio pulmonary resuscitation in patients with hypokalemia (serum potassium level <3.5
meq. L−1). Hypokalemia was found to be a predictor of serious peri-operative (OR:2.2; 95% Cl: 1.2–4.1) and post-operative arrhythmias
(OR: 1.7;95%Cl: 1.0–2.7).
Pre-operative potassium repletion is low cost and low risk treatment measure and the data from this study suggests that screening
and repletion be considered in patients scheduled for cardiac surgery. 相似文献

ABSTRACTIncreasingly intense, multifaceted, and integrated forms of surveillance are a central feature of Western national security attempts to counter the violence of “Islamic terrorism.” However, there has been a lack of research examining contemporary regimes of surveillance as profoundly racialized. This study examines how counterterrorism efforts are underpinned by ill-conceived accounts of radicalization that preemptively construct Muslim migrants as a threat to national security, thereby justifying practices of mass surveillance that further propagate racist discourses of uncertainty and risk. We advance an analysis of a racialized surveillant assemblage, which is generative of mutable, algorithmically determined profiles of the Muslim-as-terrorist. Such a regime of mass surveillance effectively puts all Muslims under suspicion. We highlight that, paradoxically, mass data-mining operations stifle, rather than aid, the identification of actual terrorist threats. This conditions a paranoid surveillant racism, through which Muslim populations become modulated as an unknowable threat of death and destruction. 相似文献

Unstable angina is a critical condition of heart resulting from narrowing of vessels supplying blood to heart. Ischemia of
the myocardium leads to oxidative stress and severe tissue damage. The objective of the present study was to determine the
effect of l-arginine administration on the oxidant–antioxidant homeostasis which otherwise gets imbalanced in patients with cardiovascular
diseases. The results obtained, show improvement in the oxidant–antioxidant levels of the subjects upon incorporation of l-arginine. Our findings suggest that supplementation of l-arginine along with regular anti-anginal therapy may be beneficial to the patients of unstable angina. 相似文献

Association of cholesteryl ester transfer protein (CETP) Gene -629C/A Polymorphism with angiographically proven atherosclerosis CETP gene has been linked to CAD risk via its role in HDL and LDL metabolism. There is no agreement of whether CETP is atherogenic or not. Furthermore, various genotypes of CETP gene have been associated with CETP levels and thus with atherosclerosis risk. Our aim was to study the association of CETP -629C/A gene polymorphism with CETP and HDL levels and their association if any with atherosclerosis. Study population consisted of angiographically documented 50 cases with coronary artery atherosclerosis and 50 controls negative for atherosclerosis of coronary artery. Serum lipid profile was measured on SYNCHRON CX-9 using standard kits. Serum CETP levels were measured by ELISA method. CETP -629C/A gene polymorphism was studied using PCR–RFLP method. There was no significant difference in lipid profile of the two groups. However, serum CETP level was significantly higher (46.44 ± 21.75 ng/ml) in cases than controls (37.10 ± 21.92 ng/ml) with p value =0.035. The frequency of -629A allele was higher (0.85) in cases than that of controls (0.81). Homozygosity of A allele was more in subjects with atherosclerosis of coronary artery. We conclude that CETP is atherogenic and could be used as atherogenic risk predictor in angiographically proven atherosclerosis. Also A allele of -629C/A polymorphism is more prevalent in cases; indicating its effect on expression of CETP gene. 相似文献

目的:探讨皮质类固醇对导管消融术后心房颤动(AF)的影响。创新点:首个探讨皮质类固醇对导管消融术后AF影响的荟萃分析。方法:我们在Pub Med、Embase和Cochrane对照试验中心注册库中搜索了描述皮质类固醇对预防导管消融后AF复发影响的文章,并提取了研究和患者的相关数据。使用随机效应模型计算风险比(RR)和95%置信区间(CI),P0.05被认为具有统计学差异。结论:导管消融术围术期皮质类固醇的使用与AF早期复发减少相关,但与晚期复发无关。 相似文献

This essay records a recent history of how dedicated and public-spirited lovers of a sport created a virtual community of cricket fans using what was then a new medium called the internet. The website “Cricinfo” was initially a product of this community. The essay then shows how commercial concerns came to override those of the virtual community, as Cricinfo was transformed from a community-based enterprise to a commercial entity. All of this happened at a time when the sport and the internet itself was being transformed by new technologies, and entrepreneurs were taking advantage of these changes to create new economic opportunities. The recent acquisition of Cricinfo by the media giant ESPN (itself owned by The Walt Disney Company) merely continues the trajectory outlined in this essay. 相似文献

INTRODUCTION The physics of plastic deformation and crack propagation at atomic level is complex but is essential for the development of new materials. This requires an understanding of the atomic level phenomena associated with the plastic deformation. In this con- text, emission of electromagnetic radiation (EMR) during plastic deformation and crack propagation in metals and alloys, and generation of transient mag- netic fields during crack initiation in ferromagnetic materials are rep… 相似文献

Sadhan Basu was an inspiring teacher and scientist and among the best that our university system has produced. He carried out important and thoughtful research work in the fields of polymers, spectroscopy and quantum chemistry that bear the signature of a highly creative mind. And all these he did with so little resources at his disposal. No wonder that his memory still inspires awe and respect among many of his immensely successful students and colleagues. 相似文献
