Retrospective assessment of inguinal hernia repair in elderly outpatients

Background In the last ten years Day Surgery has significantly evolved, due to improvements in surgery and anaesthesia, and the need of reducing long term admission costs [1]. However, is Day Surgery suitable for elderly patients? The aim of this paper is to assess the risk of over 70 year-old outpatients who underwent inguinal hernia repair, and suggest an adequate preoperative pathway

Preface for CEEPE 2020 Proceedings

Journal of Physics: Conference Series, Volume 1585, 2020 the 3rd International Conference on Energy, Electrical and Power Engineering (CEEPE 2020) 24-26 April 2020, Chongqing, ChinaThe 3rd International Conference on Energy, Electrical, and Power Engineering (CEEPE) was planned to be held in April 24-26, 2020, in Chongqing, China, and was co-sponsored by the University of Electronic Science and Technology of China; Wuhan University, China; Shandong University, China; South Asia Institute of Science and Engineering (SAISE) and IEEE PES Chongqing Chapter. Due to the unexpected COVID 19 pandemic, that closed the world to national and international travel, the organization decided to hold the CEEPE 2020 totally online. It was a challenge, not only to the organizers, but also to the participants who were delivering their speeches using videoconference tools, under different time zones. This conference brought together researchers and engineers in academia and industry from China, Iraq, Japan and Portugal to discuss the latest developments and implementation, in these countries, of electrical power in applications ranging from commercial generation and distribution, to electric vehicles, with a particular focus on renewable energy integration in power systems, automation and control systems. Although there was not the opportunity to meet face-to-face under a live social environment, attendees from different areas of the world could interact under the videoconference tool, clarify their doubts and establish business and technical connections. The proceedings of these presentations are listed here in peer reviewed, written form.info:eu-repo/semantics/publishedVersio

The Role of Oxidative Stress and Lipid Peroxidation in Ventricular Remodeling Induced by Tobacco Smoke Exposure after Myocardial Infarction

OBJECTIVE: To evaluate the roles of oxidative stress and lipid peroxidation in the ventricular remodeling that is induced by tobacco smoke exposure after myocardial infarction.METHODS: After induced myocardial infarction, rats were allocated into two groups: C (control, n=25) and ETS (exposed to tobacco smoke, n=24). After 6 months, survivors were submitted to echocardiogram and biochemical analyses.RESULTS: Rats in the ETS group showed higher diastolic (C = 1.52 +/- 0.4 mm(2), ETS = 1.95 +/- 0.4 mm(2); p=0.032) and systolic (C = 1.03 +/- 0.3, ETS = 1.36 +/- 0.4 mm(2)/g; p=0.049) ventricular areas, adjusted for body weight. The fractional area change was smaller in the ETS group (C = 30.3 +/- 10.1 %, ETS = 19.2 +/- 11.1 %; p=0.024) and E/A ratios were higher in ETS animals (C = 2.3 +/- 2.2, ETS = 5.1 +/- 2.5; p=0.037). ETS was also associated with a higher water percentage in the lung (C = 4.8 (4.3-4.8), ETS = 5.5 (5.3-5.6); p=0.013) as well as higher cardiac levels of reduced glutathione (C = 20.7 +/- 7.6 nmol/mg of protein, ETS = 40.7 +/- 12.7 nmol/mg of protein; p=0.037) and oxidized glutathione (C = 0.3 +/- 0.1 nmol/g of protein, ETS = 0.9 +/- 0.3 nmol/g of protein; p=0.008). No differences were observed in lipid hydroperoxide levels (C = 0.4 +/- 0.2 nmol/mg of tissue, ETS = 0.1 +/- 0.1 nmol/mg of tissue; p=0.08).CONCLUSION: In animals exposed to tobacco smoke, oxidative stress is associated with the intensification of ventricular re-remodeling after myocardial infarction
