Effectiveness of Light Pressure Stroking Massage Therapy on Patients' Satisfaction and Quality of Pain Control after Coronary Artery Bypass Graft Surgery

Introduction & Objective: Pain on mid-sternotomy incision site after Coronary Artery Bypass Graft Surgery (CABG) is a common problem has a negative effect on quality of life and follow-up treatment. Thus the present study aimed to determine the effect of light massage therapy by patient's Light Pressure Stroking Massage Therapy on Patients' Satisfaction and Quality of Pain Control in post-CABG patients. Materials & Methods: In this semi - experimental study, 72 post-CABG patients were randomly divided into an intervention and a control group. The intervention group received Light Pressure Stroking massage by the nurse for 20 minutes in 4 sessions. The control group received routine care. Patient’s satisfaction and quality of pain control were assessed by brief pain inventory (BPI) and Idvall quality of life questionnaire before and after the intervention. Then, the data was analyzed by student t-test, paired t-test and chi-square by SPSS software version 18. Results: Mean (SD) scores for Satisfaction and Quality of Pain Control before the intervention in the case group were 5.402±1.601 and 49.324±2.569 and in the control group were 4.452±2.123 and 48.425± 2.505 respectively, that did not show a significant difference (P > 0.05). After the intervention, Mean (SD) scores for Satisfaction and Quality of Pain Control in the case group, were 8.402±1.200 and 64.612± 2.004 and in the control group were 5.321±1.500 and 51.513±2.234 respectively, that showed a significant difference (P < 0.001). Conclusions: Regarding the finding of study, use of Light Pressure Stroking massage therapy can increase Patients' Satisfaction and Quality of Pain Control of patients after coronary artery bypass surgery and due to low cost and simplicity of this method, it can perhaps be used as a complement to drug therapy and postoperative interventions used in these patients.

The parable of “An Elephant and the Blind Men”: Comparing the approach of sociology and economics to the problem of entrepreneurship

It is not simple at all to answer as why some people become entrepreneurs while others don't. Most researchers have accepted this puzzle and defined entrepreneurship in various ways, thus, making it a controversial term to develop theories around it. In the midst of contradictory ideas in the field of entrepreneurship, the contribution of social sciences such as sociology and economics is significant. However, their perspectives on the subject differ. Sociology sees individual agency as more significant than social factors, while economics assumes the opposite. This has led to the dual perception of under-socialized and over-socialized, with both being incomplete. This duality can be compared to the blind description of an elephant in the dark - each person touches the elephant from different angles and presents own point of view to refute the other. This article aims to explain this duality and approaches of sociology and economics towards the issue of entrepreneurship. It is theoretical in nature and explores the path that flows between the two opposite poles, using the new economic sociological paradigm. This approach aims to go beyond the duality of under-socialized and over-socialized perceptions, allowing for a better understanding of entrepreneurship in its social and historical contexts

Effectiveness of light pressure stroking massage on pain and fatigue of patients after coronary artery bypass graft surgery-A randomized clinical trial

زمینه و هدف: درد و خستگی از مشکلات شایع بعد از عمل بیماران تحت جراحی پیوند عروق کرونر می باشد. هدف از این مطالعه تعیین تأثیر ماساژ درمانی بر شدت درد و خستگی بعد از عمل بیماران تحت جراحی پیوند عروق کرونر بوده است. روش بررسی: در این مطالعه کارآزمایی بالینی تصادفی سازی شده، تعداد 72 نفر بیمار تحت عمل جراحی قرارگرفته عروق کرونر در بیمارستان شهید چمران شهر اصفهان، انتخاب شدند و بطور تصادفی در دو گروه مداخله و شاهد قرار گرفتند. بیماران گروه مداخله (36 نفر)، ماساژ استروک سطحی 20 دقیقه ای به مدت 4 جلسه در 4 روز پیاپی در روزهای 3 تا 6 بعد از عمل جراحی دریافت کردند و بیماران گروه شاهد تنها مراقبت های روتین را دریافت نمودند. متغیرهای درد و خستگی قبل و بعد از مداخله با استفاده از مقیاس قیاسی دیداری ثبت شدند. یافته ها: نتایج نشان داد که اختلاف معنی داری بین شدت درد و خستگی در دو گروه مداخله و شاهد بعد از انجام مداخله وجود داشته است (0/001>P). بطوریکه کاهش میانگین شدت درد و خستگی از روز اول تا چهارم بعد از عمل در گروه مداخله بیشتر از گروه شاهد بود. نتیجه گیری: استفاده از ماساژ استروک سطحی می تواند باعث کاهش درد و خستگی بعد از عمل بیماران تحت جراحی پیوند عروق کرونر شود و با توجه به سادگی و کم هزینه بودن این روش، شاید بتواند به عنوان مکمل مناسبی برای دارودرمانی و مداخلات بعد از عمل در این بیماران مورد استفاده قرار گیرد

A study of the time of hospital discharge of differentiated thyroid cancer patients after receiving iodine-131 for thyroid remnant ablation treatment

The aim of this study was to measure the radiation exposure rate from differentiated thyroid carcinoma (DTC) patients who had received iodine-131 (131I) treatment, and to evaluate hospital discharge planning in relation to three different sets of regulations. We studied 100 patients, 78 females and 22 males, aged 13 to 79 years (mean 44.40±15.83 years) with DTC, in three Groups who were treated with 3.7, 5.5 or 7.4GBq of 131I, respectively. The external whole-body dose rates following oral administration of 131I were measured after each one of the first three hospitalization days. A multivariant linear analysis was performed, considering exposure rates as dependent variables to the administered dose for treatment, age, gender, regional and/or distant metastases, thyroglobulin (Tg), antibodies to Tg and thyroid remnant in the three dose groups. We found that the exposure rates after each of the three first days of hospitalization were 30, 50 and 70μSvh-1 at 1m. All our DTC patients had an acceptable dose rate on days 2 and 3 that allowed their hospital discharge. After only 1 day of hospitalization, just 3/11 cases showed not permissible exposure rates above 70μSvh-1. In conclusion, it is the opinion of the authors that after measuring the exposure rates, most treated, DTC patients could be discharged after only one day of hospitalization, even some of those treated with high doses of 131I (7.4GBq). Patients, who received the higher doses of 131I, should not be released before their individual exposure rate is measured

Using Data-mining Techniques for the prediction of the severity of road crashes in Cartagena, Colombia

Objective: Analyze the road crashes in Cartagena (Colombia) and the factors associated with the collision and severity. The aim is to establish a set of rules for defining countermeasures to improve road safety. Methods: Data mining and machine learning techniques were used in 7894 traffic accidents from 2016 to 2017. The severity was determined between low (84%) and high (16%). Five classification algorithms to predict the accident severity were applied with WEKA Software (Waikato Environment for Knowledge Analysis). Including Decision Tree (DT-J48), Rule Induction (PART), Support Vector Machines (SVMs), Naïve Bayes (NB), and Multilayer Perceptron (MLP). The effectiveness of each algorithm was implemented using cross-validation with 10-fold. Decision rules were defined from the results of the different methods. Results: The methods applied are consistent and similar in the overall results of precision, accuracy, recall, and area under the ROC curve. Conclusions: 12 decision rules were defined based on the methods applied. The rules defined show motorcyclists, cyclists, including pedestrians, as the most vulnerable road users. Men and women motorcyclists between 20–39 years are prone in accidents with high severity. When a motorcycle or cyclist is not involved in the accident, the probable severity is low

Artifacts In Magnetic Resonance Imaging and Computed Tomography Caused By Dental Materials

BACKGROUND: Artifacts caused by dental restorations, such as dental crowns, dental fillings and orthodontic appliances, are a common problem in MRI and CT scans of the head and neck. The aim of this in-vitro study was to identify and evaluate the artifacts produced by different dental restoration materials in CT and MRI images. METHODS: Test samples of 44 materials (Metal and Non-Metal) commonly used in dental restorations were fabricated and embedded with reference specimens in gelatin moulds. MRI imaging of 1.5T and CT scan were performed on the samples and evaluated in two dimensions. Artifact size and distortions were measured using a digital image analysis software. RESULTS: In MRI, 13 out of 44 materials produced artifacts, while in CT 41 out of 44 materials showed artifacts. Artifacts produced in both MRI and CT images were categorized according to the size of the artifact. SIGNIFICANCE: Metal based restoration materials had strong influence on CT and less artifacts in MRI images. Rare earth elements such as Ytterbium trifluoride found in composites caused artifacts in both MRI and CT. Recognizing these findings would help dental materials manufacturers and developers to produce materials which can cause less artifacts in MRI and CT images

Primary antibody deficiency in a tertiary referral hospital: A 30-year experiment

Background: Primary antibody deficiency (PAD) is the most common group of primary immunodeficiency disorders (PID), with a broad spectrum of clinical features ranging from severe and recurrent infections to asymptomatic disease. Objectives: The current study was performed to evaluate and compare demographic and clinical data in the most common types of PAD. Materials and Methods: We performed a retrospective review of the medical records of all PAD patients with a confirmed diagnosis of common variable immunodeficiency (CVID), hyper IgM syndrome (HIgM), selective IgA deficiency (SIgAD), and X-linked agammaglobulinemia (XLA) who were diagnosed during the last 30 years at the Children�s Medical Center, Tehran, Iran. Results: A total number of 280 cases of PAD (125 CVID, 32 HIgM, 63 SIgAD, and 60 XLA) were enrolled in the study. The median (range) age at the onset of disease in CVID, HIgM, SIgAD, and XLA was 2 (0-46), 0.91 (0-9), 1 (0-26), and 1 (0-10) years, respectively. Gastrointestinal infections were more prevalent in CVID patients, as were central nervous system infections in XLA patients. Autoimmune complications were more prevalent in HIgM patients, malignancies in CVID patients, and allergies in SIgAD patients. The mortality rate for CVID, HIgM, and XLA was 27.2, 28.1, and 25, respectively. No deaths were reported in SIgAD patients. Conclusions: SIgAD patients had the best prognosis. While all PAD patients should be monitored for infectious complications, special attention should be paid to the finding of malignancy and autoimmune disorders in CVID and HIgM patients, respectively. © 2015 Esmon Publicidad

Magnetic hot spots in closely spaced thick gold nanorings

This document is the Accepted Manuscript version of a Published Work that appeared in final form in Nano Letters, copyright © American Chemical Society after peer review and technical editing by the publisher. To access the final edited and published work see http://pubs.acs.org/page/policy/articlesonrequest/index.htmlLigh-matter interaction at optical frequencies is mostly mediated by the electric component of the electromagnetic field, with the magnetic component usually being considered negligible. Recently, it has been shown that properly engineered metallic nanostructures can provide a magnetic response at optical frequencies originated from real or virtual flows of electric current in the structure. In this work, we demonstrate a magnetic plasmonic mode which emerges in closely spaced thick gold nanorings. The plasmonic resonance obtains a magnetic dipole character by sufficiently increasing the height of the nanorings. Numerical simulations show that a virtual current loop appears at resonance for sufficiently thick nanorings, resulting in a strong concentration of the magnetic field in the gap region (magnetic hot spot). We find that there is an optimum thickness that provides the maximum magnetic intensity enhancement (over 200-fold enhancement) and give an explanation of this observation. This strong magnetic resonance, observed both experimentally and theoretically, can be used to build new metamaterials and resonant loop nanoantennas at optical frequencies.This work has been supported by Spanish Government and European Union (EU) funds under contracts CSD2008-00066 and TEC2011-28664-C02-02 and Universitat Politecnica de Valencia (program INNOVA 2011).
