Natural orifice translumenal endoscopic surgery: Progress in humans since white paper

引用

World Journal of Gastroenterology 2011年第13期17卷 1655-1665页

作者： Byron F santos eric s Hungness Department of surgery Feinberg School of Medicine Northwestern University Chicago IL 60611 United States

since the first description of the concept of natural orifice translumenal endoscopic surgery (NOTEs), a substantial number of clinical NOTEs reports have appeared in the literature. This editorial reviews the available human data addressing research questions originally proposed by the white paper, including determining the optimal method of access for NOTEs, developing safe methods of lumenal closure, suturing and anastomotic devices, advanced multitasking platforms, addressing the risk of infection, managing complications, addressing challenges with visualization, and training for NOTEs procedures. An analysis of the literature reveals that so far transvaginal access and closure appear to be the most feasible techniques for NOTEs, with a limited, but growing transgastric, transrectal, and transesophageal NOTEs experience in humans. The theoretically increased risk of infection as a result of NOTEs procedures has not been substantiated in transvaginal and transgastric procedures so far. Development of suturing and anastomotic devices and advanced platforms for NOTEs has progressed slowly, with limited clinical data on their use so far. Data onthe optimal management and incidence of intraoperative complications remain sparse, although possible factors contributing to complications are discussed. Finally, this editorial discusses the likely direction of future NOTEs development and its possible role in clinical practice.

Management of non-variceal upper gastrointestinal tract hemorrhage:Controversies and areas of uncertainty

引用

World Journal of Gastroenterology 2012年第11期18卷 1159-1165页

作者： eric P Trawick Patrick s Yachimski Division of Gastroenterology Hepatology and NutritionVanderbilt University Medical Center

Upper gastrointestinal tract hemorrhage （UGIH） remains a common presentation requiring urgent evaluation and treatment. Accurate assessment, appropriate intervention and apt clinical skills are needed for proper management from time of presentation to discharge. The advent of pharmacologic acid suppression, endoscopic hemostatic techniques, and recognition of Helicobacter pylori as an etiologic agent in peptic ulcer disease （PUD） has revolutionized the treatment of UGIH. Despite this, acute UGIH still carries considerable rates of morbidity and mortality. This review aims to discuss current areas of uncertainty and controversy in the management of UGIH. Neoadjuvant proton pump inhibitor （PPI） therapy has become standard empiric treatment for UGIH given that PUD is the leading cause of non variceal UGIH, and PPIs are extremely effective at promoting ulcer healing. Howeve, neoadjuvant PPI administration has not been shown to affect hard clinical outcomes such as rebleeding or mortality. The optimal timing of upper endoscopy in UGIH is often debated. Upon completion of volume resuscitation and hemodynamic stabilization, upper endoscopy should be performed within 24 h in all patientswith evidence of UGIH for both diagnostic and therapeutic purposes. With rising healthcare cost paramount in today＇s medical landscape, the ability to appropriately triage UGIH patients is of increasing value. Upper en- doscopy in conjunction with the clinical scenario allows for accurate decision making concerning early discharge home in low risk lesions or admission for further moni toring and treatment in higher risk lesions. Concomitant pharmacotherapy with non steroidal antiinflammatory drugs （NsAIDs） and antiplatelet agents, such as clopidogrel, has a major impact on the etiology, severib/, and potential treatment of UGIH. Long term PPI use in patients taking chronic NsAIDs or clopidogrel is discussed thoroughly in this review.

Molecular genetics and targeted therapeutics in biliary tractcarcinoma

The primary malignancies of the biliary tract, cholangio-carcinoma and gallbladder cancer, often present at an advanced stage and are marginally sensitive to radiation and chemotherapy. Accumulating evidence indicates that molecularly targeted agents may provide new hope for improving treatment response in biliary tract carcinoma(BTC). In this article, we provide a critical review of the pathogenesis and genetic abnormalities of biliary tract neoplasms, in addition to discussing the current and emerging targeted therapeutics in BTC. Genetic studies of biliary tumors have identified the growth factors and receptors as well as their downstream signaling pathways that control the growth and survival of biliary epithelia. Target-specific monoclonal antibodies and small molecules inhibitors directed against the signaling pathways that drive BTC growth and invasion have been developed. Numerous clinical trials designed to test these agents as either monotherapy or in combination with conventional chemotherapy have been completed or are currently underway. Research focusing on understanding the molecular basis of biliary tumorigenesis will continue to identify for targeted therapy the key mutations that drive growth and invasion of biliary neoplasms. Additional strategies that have emerged for treating this malignant disease include targeting the epigenetic alterations of BTC and immunotherapy. By integrating targeted therapy with molecular profiles of biliary tumor, we hope to provide precision treatment for patients with malignant diseases of the biliary tract.

Natural Hazard-Induced Disasters and Production Efficiency:Moving Closer to or Further from the Frontier?

引用

International Journal of Disaster Risk science 2019年第2期10卷 166-178页

作者： Preeya s.Mohan Nekeisha spencer eric strobl sir Arthur Lewis Institute of social and Economic studies(sALIsEs) University of the West IndiesSt AugustineTrinidad and Tobago University of the West Indies MonaKingstonJamaica University of Bern 3012BernSwitzerland

Production efficiency is a key determinant of economic growth and demonstrates how a country uses its resources by relating the quantity of its inputs to its outputs. When a natural hazard-induced disaster strikes, it has a devastating impact on capital and labor, but at the same time provides an opportunity to upgrade capital and increase labor demand and training opportunities, thereby potentially boosting production efficiency. We studied the impact of natural hazard-induced disasters on countries’ production efficiency, using the case study of hurricanes in the Caribbean. To this end we built a country-specific,time-varying data set of hurricane damage and national output and input indicators for 17 Caribbean countries for the period 1940–2014. Our results, using a stochastic frontier approach, show that there is a short-lived production efficiency boost, and that this can be large for very damaging storms.

Retrieving Phenomenology： Introduction to the special Theme

引用

Frontiers of Philosophy in China 2016年第3期11卷 329-337页

作者： eric s. Nelson Hong Kong University of science and Technology

Phenomenology ordinarily signifies the investigation （logos） of that which appears （phainomenon）. It is frequently understood, outside of phenomenology as a philosophical movement, to be experiential description from the first person perspective. Critics of phenomenology, including contemporary critics as diverse as Daniel Dennett and John searle, as well as speculative realism and object oriented ontology, construe it as being intrinsically subjective, idealistic, and trapped in the first-person point of view （Dennett 2003, 19-30; searle 2008, 107-36; sparrow 2014; Zahavi 289-309）.
