1重新审视中国高龄老人血压与死亡风险之间的关系:以社区为基础的纵向前瞻性队列研究显示文摘目的探讨中国高龄老人血压与3年全因死亡风险和死因别死亡风险之间的关系。研究设计以社区为基础的纵向前瞻性队列研究。研究地点2011和2014年在中国22个省份开展的两轮中国老年健康影响因素跟踪调查。研究对象4658名高龄老人(平均年龄为92.1岁)。主要结局指标随访3年全因死亡和死因别死亡。结果经过3年的随访,共计1977人死亡,收缩压(SBP)、平均动脉压(MAP)、脉压差(PP)与死亡风险间呈U型关系,SBP、MAP和PP在143.5、101和66mmHg时死亡风险最低。对混杂因素进行调整后,仅SBP与死亡风险的U型关系存在,风险最低点为129mmHg。与129mmHg的人群相比,SBP低于107mmHg时,死亡风险随SBP的升高而降低[风险比(HR)从1.47(1.01~2.17)到1.08(1.01~1.17)1;SBP高于154mmHg时,死亡风险随SBP的升高而增加[HR从1.08(1.01~1.17)到1.27(1.02~1.58)]。在死因别分析中,与中等水平SBP(107~154mmHg)相比,高水平的SBP(〉154mmHg)与心血管疾病(CVD)死亡风险升高相关联[调整HR1.51(1.12~2.02)];低水平SBP(〈107mmHg)与非CVD死亡风险升高相关联[调整HR1.58(1.26~1.98)]。在敏感性分析与亚组分析中血压与死亡风险的U型关系保持不变。结论研究在中国高龄老人中发现SBP与3年全因死亡风险呈U型关系,高SBP意味着更高的CVD死亡风险,低SBP意味着更高的非CVD死亡风险。这提示高龄老人目前的血压管理理念有待重新评估,可能需要针对这一特殊人群制定特定的血压指南。吕跃斌 高翔 殷召雪 陈华帅 罗杰斯 Melanie Sereny Brasher Virginia Byers Kraus 李湉湉 曾毅 施小明 张希如(译) 毛琛(校) 2018英国医学杂志中文版2018,21,8:17

3All-silicon carrier accumulation modulator based on a lateral metal-oxide-semiconductor capacitor显示文摘In silicon photonics, the carrier depletion scheme has been the most commonly used mechanism for demonstrating high-speed electro-optic modulation. However, in terms of phase modulation efficiency, carrieraccumulation-based devices potentially offer almost an order of magnitude improvement over those based on carrier depletion. Previously reported accumulation modulator designs only considered vertical metal-oxidesemiconductor(MOS) capacitors, which imposes serious restrictions on the design flexibility and integratability with other photonic components. In this work, for the first time to our knowledge, we report experimental demonstration of an all-silicon accumulation phase modulator based on a lateral MOS capacitor. Using a Mach–Zehnder interferometer modulator with a 500-μm-long phase shifter, we demonstrate high-speed modulation up to 25 Gbit∕s with a modulation efficiency(V_πL_π) of 1.53 V·cm.KAPIL DEBNATH DAVID J.THOMSON WEIWEI ZHANG ALI Z.KHOKHAR CALLUM LITTLEJOHNS JAMES BYERS LORENZO MASTRONARDI MUHAMMAD K.HUSAIN KOUTA IBUKURO FREOERIC Y.GARDES GRAHAM T,REED SHINICHI SAITO 2018Photonics Research2018,6,5:6

5Infant with cardiomyopathy: When to suspect inborn errors of metabolism?显示文摘Inborn errors of metabolism are identified in 5%-26% of infants and children with cardiomyopathy. Although fatty acid oxidation disorders, lysosomal and glycogen storage disorders and organic acidurias are well-known to be associated with cardiomyopathies, emerging reports suggest that mitochondrial dysfunction and congenital disorders of glycosylation may also account for a proportion of cardiomyopathies. This review article clarifies when primary care physicians and cardiologists should suspect inborn errors of metabolism in a patient with cardiomyopathy, and refer the patient to a metabolic specialist for a further metabolic work up, with specific discussions of 'red flags' which should prompt additional evaluation.Stephanie L Byers Can Ficicioglu 2014World Journal of Cardiology2014,6,11:3
6经常服用鱼油补充剂与心血管疾病结局和全因死亡风险之间的关系:基于大型人群队列研究的证据显示文摘目的在一个大型的前瞻性队列中探讨经常服用鱼油补充剂与心血管疾病(CVD)及死亡风险之间的关系。研究设计基于人群的前瞻性队列研究。研究背景英国生物银行。研究对象在2006—2010年期间,共招募427678名在基线时没有CVD或癌症病史且年龄在40~69岁之间的男性和女性,并一直随访至2018年底。主要暴露所有研究对象均回答了经常服用补充剂(包括鱼油)的情况。主要结局指标全因死亡风险、CVD死亡风险和CVD事件。结果在基线时,427678名研究对象中有133438名(31.2%)报告了有经常服用鱼油补充剂的情况。经常服用鱼油补充剂与不服用鱼油补充剂的研究对象经多变量校正后的风险比(HR)值(95%可信区间)分别为:全因死亡风险0.87(0.83~0.90),CVD死亡风险0.84(0.78~0.91),CVD事件0.93(0.90~0.96)。经常服用鱼油补充剂与CVD事件之间的关联在高血压人群中似乎更强(交互P值=0.005)。结论经常服用鱼油补充剂可降低全因及心血管疾病的死亡风险,并对心血管疾病事件具有边际保护作用。李志浩 钟文芳 刘思敏 Kraus Virginia Byers 张宇杰 高翔 吕跃斌 申动 张希如 张沛东 黄清湄 陈清 吴娴波 施小明 王冬 毛琛 2020英国医学杂志中文版2020,23,6:3

8Deliberate release:Plague-A review显示文摘Yersinia pestis is the causative agent of plague and is considered one of the most likely pathogens to be used as a bioweapon.In humans,plague is a severe clinical infection that can rapidly progress with a high mortality despite antibiotic therapy.Therefore,early treatment of Y.pestis infection is crucial.This review provides an overview of its clinical manifestations,diagnosis,treatment,prophylaxis,and protection requirements for the use of clinicians.We discuss the likelihood of a deliberate release of plague and the feasibility of obtaining,isolating,culturing,transporting and dispersing plague in the context of an attack aimed at a westernized country.The current threat status and the medical and public health responses are reviewed.We also provide a brief review of the potential prehospital treatment strategy and vaccination against Y.pestis.Further,we discuss the plausibility of antibiotic resistant plague bacterium,F1-negative Y.pestis,and also the possibility of a plague mimic along with potential strategies of defense against these.An extensive literature search on the MEDLINE,EMBASE,and Web of Science databases was conducted to collate papers relevant to plague and its deliberate release.Our review concluded that the deliberate release of plague is feasible but unlikely to occur,and that a robust public health response and early treatment would rapidly halt the transmission of plague in the population.Front-line clinicians should be aware of the potential of a deliberate release of plague and prepared to instigate early isolation of patients.Moreover,front-line clinicians should be weary of the possibility of suicide attackers and mindful of the early escalation to public health organizations.Issmaeel Ansari Gareth Grier Mark Byers 2020Journal of Biosafety and Biosecurity2020,2,1:2
9Associations of Sarcopenia, Handgrip Strength and Calf Circumference with Cognitive Impairment among Chinese Older Adults显示文摘Objective To evaluate the associations of sarcopenia,handgrip strength and calf circumference with cognitive impairment among Chinese older adults.Methods Totally 2,525 older adults were recruited from the Healthy Aging and Biomarkers Cohort Study.Cognitive impairment was assessed by the Chinese Mini-Mental State Examination.Handgrip strength was calculated from the means of the right and left hand values.Calf circumference was measured at the site of maximum circumference of the non-dominant leg.The formula developed by Ishii was used to define sarcopenia.Multiple logistic regression was performed to evaluate the associations of sarcopenia,handgrip strength,and calf circumference with cognitive impairment.Results The prevalence of cognitive impairment was 34.36%.The adjusted odds ratio(OR)for cognitive impairment in individuals with sarcopenia was 2.55[95% confidence interval(95%CI):1.86-3.50].Compared with individuals in the first quartile(Q1)of calf circumference,the adjusted ORs in the second,third,and fourth quartiles(Q_(2),Q_(3),and Q_(4))were 0.75(95% CI:0.58-0.96),0.59(95% CI:0.44-0.79),and 0.62(95% CI:0.45-0.8),respectively.Compared with individuals in Q1 of handgrip strength,the adjusted ORs for Q_(2),Q_(3),and Q_(4) were 0.49(95%CI:0.38-0.62),0.31(95% CI:0.23-0.41),and 0.30(95%CI:0.21-0.44),respectively.Conclusion Sarcopenia,identified by low handgrip strength and low calf circumference,was positively associated with cognitive impairment.WU Bing LYU Yue Bin CAO Zhao Jin WEI Yuan SHI Wan Ying GAO Xiang ZHOU Jin Hui KRAUS Virginia Byers ZHAO Feng CHEN Xin LU Feng ZHANG Ming Yuan LIU Ying Chun TAN Qi Yue SONG Shi Xun QU Ying Li ZHENG Xu Lin SHEN Chong MAO Chen SHI Xiao Ming 2021Biomedical and Environmental Sciences2021,34,11:2
