| 1 | Neurologic complications and neurodevelopmental outcome with extracorporeal life support显示文摘Extracorporeal life support is used to support patients of all ages with refractory cardiac and/or respiratory failure. Extracorporeal membrane oxygenation(ECMO)has been used to rescue patients whose predicted mortality would have otherwise been high. It is associated with acute central nervous system(CNS) complications and with long- term neurologic morbidity. Many patients treated with ECMO have acute neurologic complications, including seizures, hemorrhage, infarction, and brain death. Various pre-ECMO and ECMO factors have been found to be associated with neurologic injury, including acidosis, renal failure, cardiopulmonary resuscitation, and modality of ECMO used. The risk of neurologic complication appears to vary by age of the patient, with neonates appearing to have the highest risk of acute central nervous system complications. Acute CNS injuries are associated with increased risk of death in a patient who has received ECMO support. ECMO is increasingly used during cardiopulmonary resuscitation when return of spontaneous circulation is not achieved rapidly and outcomes may be good in select populations. Economic analyses have shown that neonatal and adult respiratory ECMO are cost effective. There have been several intriguing reports of active physical rehabilitation of patients duringECMO support that is well tolerated and may improve recovery. Although there is evidence that some patients supported with ECMO appear to have very good outcomes, there is limited understanding of the longterm impact of ECMO on quality of life and long-term cognitive and physical functioning for many groups, especially the cardiac and pediatric populations. This deserves further study. | Amit Mehta Laura M Ibsen | 2013 | World Journal of Critical Care Medicine2013，2，4： | 12 |
| 2 | Magnetic anchor guidance for endoscopic submucosal dissection and other endoscopic procedures显示文摘Endoscopic submucosal dissection(ESD) is a wellestablished, minimally invasive treatment for superficial neoplasms of the gastrointestinal tract. The universal adoption of ESD has been limited by its slow learning curve, long procedure times, and high risk of complications. One technical challenge is the lack of a second hand that can provide traction, as in conventional surgery. Reliable tissue retraction that exposes the submucosal plane of dissection would allow for safer and more efficient dissection. Magnetic anchor guided endoscopic submucosal dissection(MAGESD) has potential benefits compared to other current traction methods. MAG-ESD offers dynamic tissue retraction independent of the endoscope mimicking a surgeon's 'second hand'. Two types of magnets can be used: electromagnets and permanent magnets. In this article we review the MAG-ESD technology, published work and studies of magnets in ESD. We also review the use of magnetic anchor guidance systems in natural orifice transluminal endoscopic surgery and the idea of magnetic non-contact retraction using surface ferromagentization. We discuss the current limitations, the future potential of MAG-ESD and the developments needed for adoption of this technology. | Mohamed Mortagy Neal Mehta Mansour A Parsi Seiichiro Abe Tyler Stevens John J Vargo Yutaka Saito Amit Bhatt | 2017 | World Journal of Gastroenterology2017，23，16： | 12 |
| 3 | Gastric food retention at endoscopy is associated with severity of liver cirrhosis显示文摘BACKGROUND Gastrointestinal symptoms are prevalent in patients with cirrhosis.Cirrhotic patients have a known predilection to delayed gastric emptying compared to those without cirrhosis.However,the contributing factors have not been fully elucidated.Retained gastric food on esophagogastroduodenoscopy(EGD)has been used as a surrogate marker for delayed gastric emptying with reasonably high specificity.Therefore,we hypothesize that the frequency of retained gastric food contents at EGD will be higher in a cirrhotic population compared to a control population without liver disease.Additionally,we hypothesize that increased frequency of gastric food contents will be associated with increased severity of cirrhosis.AIM To determine the relative frequency of delayed gastric emptying among cirrhotics as compared to non-cirrhotics and to identify associated factors.METHODSWe performed a retrospective case-control study of cirrhotic subjects whounderwent EGD at an academic medical center between 2000 and 2015. Threehundred sixty-four patients with confirmed cirrhosis, who underwent a total of1044 EGDs for the indication of esophageal variceal screening or surveillance,were identified. During the same period, 519 control patients without liverdisease, who underwent a total of 881 EGDs for the indication of anemia, wereidentified. The presence of retained food on EGD was used as a surrogate fordelayed gastric emptying. The relative frequency of delayed gastric emptyingamong cirrhotics was compared to non-cirrhotics. Characteristics of patients withand without retained food on EGD were compared using univariable andmultivariable logistic regression analysis to identify associated factors.RESULTSOverall, 40 (4.5%) patients had evidence of retained food on EGD. Cirrhotics weremore likely to have retained food on EGD than non-cirrhotics (9.1% vs 1.4%, P <0.001). Characteristics associated with retained food on univariable analysisincluded age less than 60 years (12.6% vs 5.2%, P = 0.015), opioid use (P = 0.004),Child-Pugh class C (24.1% Child-Pugh class C vs 6.4% Child-Pugh class A, P =0.007), and lower platelet count (P = 0.027). On multivariate logistic regressionanalysis, in addition to the presence of cirrhosis (adjusted OR = 5.83;95%CI: 2.32-14.7, P < 0.001), diabetes mellitus (types 1 and 2 combined) (OR = 2.34;95%CI:1.08-5.06, P = 0.031), opioid use (OR = 3.08;95%CI: 1.29-7.34, P = 0.011), andChild-Pugh class C (OR = 4.29;95%CI: 1.43-12.9, P = 0.01) were also associatedwith a higher likelihood of food retention on EGD.CONCLUSIONCirrhotics have a higher frequency of retained food at EGD than non-cirrhotics.Decompensated cirrhosis, defined by Child-Pugh class C, is associated with ahigher likelihood of delayed gastric emptying. | David B Snell Shirley Cohen-Mekelburg Russell Weg Gaurav Ghosh Adam P Buckholz Amit Mehta Xiaoyue Ma Paul J Christos Arun B Jesudian | 2019 | World Journal of Hepatology2019，11，11： | 2 |

| 14 | Systematic review with expert consensus on use of extracorporeal hemoadsorption in septic shock:An Indian perspective显示文摘BACKGROUND Septic shock is a severe form of sepsis characterised by deterioration in circulatory and cellular-metabolic parameters.Despite standard therapy,the outcomes are poor.Newer adjuvant therapy,such as CytoSorb®extracorporeal haemoadsorption device,has been investigated and shown promising outcome.However,there is a lack of some guidance to make clinical decisions on the use of CytoSorb®haemoadsorption as an adjuvant therapy in septic shock in Indian Setting.Therefore,this expert consensus was formulated.AIM To formulate/establish specific consensus statements on the use of CytoSorb®haemoadsorption treatment based on the best available evidence and contextualised to the Indian scenario.METHODS We performed a comprehensive literature on CytoSorb®haemoadsorption in sepsis,septic shock in PubMed selecting papers published between January 2011 and March 20232021 in English language.The statements for a consensus document were developed based on the summarised literature analysis and identification of knowledge gaps.Using a modified Delphi approach combining evidence appraisal and expert opinion,the following topics related to CytoSorb®in septic shock were addressed:need for adjuvant therapy,initiation timeline,need for Interleukin-6 levels,duration of therapy,change of adsorbers,safety,prerequisite condition,efficacy endpoints and management flowchart.Eleven expert members from critical care,emergency medicine,and the intensive care participated and voted on nine statements and one open-ended question.RESULTS Eleven expert members from critical care,emergency medicine,and the intensive care participated and voted on nine statements and one open-ended question.All 11 experts in the consensus group(100%)participated in the first,second and third round of voting.After three iterative voting rounds and adapting two statements,consensus was achieved on nine statements out of nine statements.The consensus expert panel also recognised the necessity to form an association or society that can keep a registry regarding the use of CytoSorb®for all indications in the open-ended question(Q10)focusing on“future recommendations for CytoSorb®therapy”.CONCLUSION This Indian perspective consensus statement supports and provides guidance on the use of CytoSorb®haemoadsorption as an adjuvant treatment in patients with septic shock to achieve optimal outcomes. | Yatin Mehta Abdul Samad Ansari Amit Kumar Mandal Dipanjan Chatterjee Gauri Shankar Sharma Prachee Sathe Purvesh V Umraniya Rajib Paul Sachin Gupta Vinod Singh Yogendra Pal Singh | 2024 | World Journal of Critical Care Medicine2024，13，1： | 0 |
| 15 | Practical realization of dual S arm antenna for beam steering applications显示文摘A dual S shaped micro strip antenna with a realistic feed is proposed for generation of tilted beam radiation pattern pertaining for beam steering applications. To achieve this, four feeding points are located at a distance of 5.6 mm from the antenna centre. These feeding points when excited one by one generate four tilted beams in four different space quadrants, thus yielding a beam steerable antenna. Importantly, since the proposed antenna is symmetrical in the structure, all the four tilted beams have the same radiation pattern characteristics. A further enhancement of the antenna bandwidth is also achieved using 100-μm capacitive coupling between the feed and the antenna strip. | MEHTA Amit | 2007 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2007，8，12： | 0 |
