Aspects of the non-pharmacological treatment of irritable bowel syndrome

World Journal of Gastroenterology 2015年第40期21卷 11439-11449页

作者： Elsa Maria Eriksson Kristina Ingrid Andrén goran karl kurlberg Henry Ture Eriksson Department of Functional Gastroenterology Pavilion 2Sahlgrenska University Hospital/Ostra

Irritable bowel syndrome(IBS) is one of the most commonly diagnosed gastrointestinal conditions. It represents a significant healthcare burden and remains a clinical challenge. Over the years IBS has been described from a variety of different perspectives; from a strict illness of the gastrointestinal tract(medical model) to a more complex multi-symptomatic disorder of the brain-gut axis(biopsychosocial/psychosomatic model). In this article we present aspects of the pathophysiology and the non-pharmacological treatment of IBS based on current knowledge. Effects of conditioned stress and/or traumatic influences on the emotional system(top-down) as well as effects on the intestine through stressors,infection,inflammation,food and dysbiosis(bottom-up) can affect braingut communication and result in dysregulation of the autonomic nervous system(ANS),playing an important role in the pathophysiology of IBS. Conditioned stress together with dysregulation of the autonomic nervous system and the emotional system may involve reactions in which the distress inside the body is not recognized due to low body awareness. This may explain why patients have difficulty identifying their symptoms despite dysfunction in muscle tension,movement patterns,and posture and biochemical functions in addition to gastrointestinal symptoms. IBS shares many features with other idiopathic conditions,such as fibromyalgia,chronic fatigue syndrome and somatoform disorders. The key to effective treatment is a thorough examination,including a gastroenterological examination to exclude other diseases along with an assessment of body awareness by a body-mind therapist. The literature suggests that early interdisciplinary diagnostic cooperation between gastroenterologists and body-mind therapists is necessary. Re-establishing balance in the ANS is an important component of IBS treatment. This article discusses the current knowledge of body-mind treatment,addressing the topic from a practical point of view

Optimal Offering of Energy Storage in UK Day-Ahead Energy and Frequency Response Markets

引用

Journal of Modern Power Systems and Clean Energy 2024年第2期12卷 415-426页

作者： Makedon Karasavvidis Andreas Stratis Dimitrios Papadaskalopoulos goran Strbac Department of Electrical and Electronic Engineering Imperial College LondonLondonUK Statkraft UK Ltd. LondonUK Department of Electrical and Computer Engineering University of PatrasPatrasGreece IEEE

The offering strategy of energy storage in energy and frequency response(FR) markets needs to account for country-specific market regulations around FR products as well as FR utilization factors, which are highly uncertain. To this end, a novel optimal offering model is proposed for stand-alone price-taking storage participants, which accounts for recent FR market design developments in the UK, namely the trade of FR products in time blocks, and the mutual exclusivity among the multiple FR products. The model consists of a day-ahead stage, devising optimal offers under uncertainty, and a real-time stage, representing the storage operation after uncertainty is materialized. Furthermore, a concrete methodological framework is developed for comparing different approaches around the anticipation of uncertain FR utilization factors(deterministic one based on expected values, deterministic one based on worst-case values, stochastic one, and robust one), by providing four alternative formulations for the real-time stage of the proposed offering model, and carrying out an out-of-sample validation of the four model instances. Finally, case studies employing real data from UK energy and FR markets compare these four instances against achieved profits, FR delivery violations, and computational scalability.
