1Coronary artery disease in congenital single coronary artery in adults:A Dutch case series显示文摘AIM:To assess the current diagnostic and therapeutic management and the clinical implications of congenital single coronary artery(SCA) in adults.METHODS:We identified 15 patients with a SCA detected from four Dutch angiography centers in the period between 2010 and 2013.Symptomatic patients who underwent routine diagnostic coronary angiography(CAG) for suspected coronary artery disease and who incidentally were found to have isolated SCA were analyzed.RESULTS:Fifteen(7 females) with a mean age of 58.5 ± 13.78 years(range 43-86) had a SCA.ConventionalCAG demonstrated congenital isolated SCA originating as a single ostium from the right sinus of Valsalva in 6 patients and originating from the left in 9 patients.Minimal to moderate coronary atherosclerotic changes were found in 4,and severe stenotic lesions in another 4 patients.Seven patients were free of coronary atherosclerosis.Runs of non-sustained ventricular tachycardia were documented in 2 patients,one of whom demonstrated transmural ischemic changes on presentation.Myocardial perfusion scintigraphic evidence of transmural myocardial ischemia was found in 1 patient due to kinking and squeezing of the SCA with an interarterial course between the aorta and pulmonary artery.Multi-slice computed tomography(MSCT) was helpful to delineate the course of the anomalous artery relative to the aorta and pulmonary artery.Percutaneous coronary intervention was successfully performed in 3 patients.Eight patients were managed medically.Arterial bypass graft was performed in 4 patients with the squeezed SCA.CONCLUSION:SCA may be associated with transient transmural myocardial ischemia and aborted sudden death in the absence of coronary atherosclerosis.The availability and sophistication of MSCT facilitates the delineation of the course of a SCA.We present a Dutch case series and review of the literature.Salah AM Said Willem G de Voogt Suat Bulut Jacques Han Peter Polak Rogier LG Nijhuis Jeroen W op den Akker Andries Slootweg 2014World Journal of Cardiology2014,6,4:3
2Understanding the Removal and Fate of Selected Drugs of Abuse in Sludge and Biosolids from Australian Wastewater Treatment Operations显示文摘Illicit and pharmaceutical drugs are considered to be emerging contaminants of concern,and much research effort has gone into assessing their occurrence in wastewater.However,little information exists on their presence in treated sludge or biosolids.In this study,we examined sludge and biosolids from a large metropolitan wastewater treatment plant(WWTP)in Australia to determine the occurrence of five drugs of abuse,including benzoylecgonine as indicator of cocaine consumption,methamphetamine and 3,4-methylenedioxy methamphetamine(MDMA)as representative illicit stimulants,and codeine and morphine as pharmaceuticals with potential environmental risk.The samples were solid-phase extracted and analyzed by liquid chromatography–tandem mass spectrometry(LC–MS/MS).Benzoylecgonine and MDMA were present in raw sludge but were notably degraded during solids treatment processes,and were not detected in the dewatered sludge(after treatment)or in biosolids.Methamphetamine,codeine,and morphine were detected in all biosolids samples at mean concentrations of 20–50 lg kg^-1.The presence of these three drugs in biosolids shows that these compounds are relatively stable in the solids and in soil,and can persist in biosolids for at least several years.A simple environmental risk assessment based on estimated risk quotients(RQs)for these compounds indicated that the potential environmental risks associated with the land application of biosolids are very low at typical Australian biosolids application rates.Meena K.Yadav Cobus Gerber Christopher P.Saint Ben Van den Akker Michael D.Short 2019Engineering2019,5,5:3
3多病并存的多重挑战 这个时代已经到来——关注日益增长的脆弱人群的需求显示文摘多病并存(或称多重病)现象在初级卫生保健中已不是个别现象。最近在加拿大魁北克省沙格奈河地区进行的一项有21个社区医院参加的研究表明,在18~44岁组多重病的患病率为69%,45~64岁组为93%,65岁以上组达到98%,患慢性病的个数在年轻组为2.8而在老年组升至6.4。其他国家也报告了类似的疾病负担状况,如美国多病并存的患者人数将由2000年的6000万上升到2020年的8100万。Martin Fortin Hassan Soubhi Catherine Hudon Elizabeth A Bayliss Marian van den Akker 赛晓勇 2007英国医学杂志中文版2007,10,5:2
