AbstractWe explore the migration-trade nexus in the case of Germany over the period 2000-09, disentangling the two dimensions of intra-industry trade (vertical and horizontal). We find that immigration is positively and significantly related to intraindustry trade. However, the magnitude and statistical significance of migration’s impact on trade are considerably higher for horizontal intra-industry trade and increase with the difference in the level of development between Germany and the partner countries. This pattern is consistent with the view that information flows between migrant communities and their country of origin may be more important for consumer goods (where trade in varieties prevails) and that this information effect is more important if trading countries are very different.

Abstract Aim The number of Hungarian polio patients can be estimated at approximately 3000. Polio infection is currently affecting people 56–65 years of age. The aim of the study was to reveal the quality of life of patients living with polio virus in Hungary. Subject and methods The quantitative cross-sectional study was conducted in January–April 2017 among polyomyelitis patients living in Hungary. In the non-random, targeted, expert sample selection, the target group was composed of patients infected with poliovirus (N = 268). We have excluded those who refused to sign the consent statement. Our data collection method was an SF-36 questionnaire. Using the IBM SPSS Statistics Version 22 program, descriptive and mathematical statistics (χ2-test) were calculated (p < 0.05). Results The mean age of the members of the examined population is 63.5 years; 68.1% were women and 31.90% were men. The majority of the respondents were infected by the polyovirus in 1956 (11.9%), 1957 (24.3%), and 1959 (19.5%). Polio patients, with the exception of two dimensions (mental health, social operation), on the scale of 100 do not reach the “average” quality of life (physical functioning 23 points, functional role 36 points, emotional role 47 points, body pain 48 points, general health 42 points, vitality 50 points, health change 31 points). Conclusion The quality of life of polio patients is far below the dimensions of physical function, while the difference in mental health compared to healthy people is minimal. It would be important to educate health professionals about the existing disease, to develop an effective rehabilitation method.

BACKGROUND:The aim of this study was to evaluate the information quality of YouTube videos on hallux valgus. METHODS:A YouTube search was performed using the keyword 'hallux valgus' to determine the first 300 videos related to hallux valgus. A total of 54 videos met our inclusion criteria and evaluated for information quality by using DISCERN, Journal of the American Medical Association (JAMA) and hallux valgus information assessment (HAVIA) scores. Number of views, time since the upload date, view rate, number of comments, number of likes, number of dislikes, video power index (VPI) values were calculated to determine video popularity. Video length (sec), video source and video content were also noted. The relation between information quality and these factors were statistically evaluated. RESULTS:The mean DISCERN score was 30.35{plus minus}11.56 (poor quality) (14-64), the mean JAMA score was 2.28{plus minus}0.96 (1-4), and the mean HAVIA score was 3.63{plus minus}2.42 (moderate quality) (0.5-8.5). Although videos uploaded by physicians had higher mean DISCERN, JAMA, and HAVIA scores than videos uploaded by non-physicians, the difference was not statistically significant. Additionally, view rates and VPI values were higher for videos uploaded by health channels, but the difference did not reach statistical significance. A statistically significant positive correlation was found between video length and DISCERN (r= 0.294, p= 0.028), and HAVIA scores (r= 0.326, p= 0.015). CONCLUSIONS:This present study demonstrated that the quality of information available on YouTube videos about hallux valgus was low and insufficient. Videos containing accurate information from reliable sources are needed to educate patients on hallux valgus, especially in less frequently mentioned topics such as postoperative complications and healing period.

Introduction. Early signs of response after applying wafers of carmustine-loaded polymers (gliadel) are difficult to assess with imaging because of time-related imaging changes.Tc99m-sestamibi (MIBI) brain single-photon emission tomography (SPET) has reportedly been used to reveal areas of cellularity distinguishing recurrent neoplasm from radionecrosis. Our aim was to explore the role of MIBI SPET in assessing response soon after gliadel application in glioblastoma multiforme (GBM).Methods. We retrospectively reviewed the charts on 28 consecutive patients with a radiological diagnosis of GBM who underwent MIBI SPET/CT before surgery (with intracavitary gliadel placement in 17 patients), soon after surgery, and at 4 months. The area of uptake was selected using a volume of interest that was then mirrored contralaterally to obtain a semiquantitative ratio.Results. After adjusting for ratio at the baseline, the effect of treatment (gliadel versus non-gliadel) was not statistically significant. Soon after surgery, however, 100% of patients treated with gliadel had a decreased ratio, as opposed to 62.5% of patients in the non-gliadel groupP=0.0316. The difference between ratios of patients with radical versus partial resection reached statistical significance by a small marginP=0.0528.Conclusions. These data seem to suggest that the MIBI ratio could be a valuable tool for monitoring the effect of gliadel early after surgery.

A structured collection of tools for engineering resilience and a research approach to improve the resilience of a power grid are described in this paper. The collection is organized by a two-dimensional array formed from typologies of power grid components and business processes. These two dimensions provide physical and operational outlooks, respectively, for a power grid. The approach for resilience research is based on building a simulation model of a power grid which utilizes a resilience assessment equation to assess baseline resilience to a hazards’ profile, then iteratively selects a subset of tools from the collection, and introduces these as interventions in the power grid simulation model. Calculating the difference in resilience associated with each subset supports multicriteria decision-making to find the most convenient subset of interventions for a power grid and hazards’ profile. Resilience is an emergent quality of a power grid system, and therefore resilience research and interventions must be system-driven. This paper outlines further research required prior to the practical application of this approach.

385 Background: Atu027 is a liposomally formulated short interfering RNA with anti-metastatic activity, which silences expression of protein kinase N3 (PKN3) in the vascular endothelium. PKN3 acts as a Rho effector downstream of PI3K. This trial was designed to assess safety, pharmacokinetics and efficacy of Atu027 in combination with gemcitabine in advanced pancreatic carcinoma (APC). Methods: 23 patients (pts) with APC stage 3 or 4 were enrolled and randomly assigned to different Atu027 dosing schedules (arm 1: 0.253mg/kg once weekly, n = 11; arm 2: 0.253mg/kg twice-weekly, n = 12) but identical gemcitabine regimen. Response was evaluated according to RECIST 1.1. Quality of life was assessed with EORTC questionnaire QLQ-C30. Results: Combination therapy with Atu027 and gemcitabine was given up to 7.8 months until progression. Grade 3 adverse events (AEs) were reported by 9/11 pts (82%) in arm 1 and 11/12 pts (92%) in arm 2. Grade 4 AEs were reported by two pts in each arm. Interestingly, there was a difference in median progression free survival (mPFS) between the two treatment arms. Arm 1 showed an mPFS of 1.8 [95%CI: 0.4-5.5] months vs. 5.3 [95%CI: 1.5-6.0] months in arm 2, p= 0.399. In a post-hoc analysis of metastatic disease only, the difference in mPFS between the two arms reached statistical significance (1.6 [95%CI:0.4-2.1] vs 2.9 [95%CI:1.0-7.3] months, n = 9 vs 10, p= 0.025). Disease control during treatment was achieved in 4/11 (36%) pts in arm 1 and in 7/12 (58%) pts in arm 2. New lesions occurred in all (6/6) pts in arm 1 who had at least one RECIST re-evaluation but only 5/10 pts (50%) in arm 2. In quality of life analysis, pts in the once-weekly arm showed a stable global health status while pts in the twice-weekly arm reported an improvement (0-100 score change from baseline: -2.3 vs +21.6 after one cycle, N = 7 vs 7). Conclusions: Combination of Atu027 with gemcitabine for the treatment of APC is safe and was well tolerated. Despite the small patient number, there is a clear signal that twice-weekly Atu027 dosing might be superior to the once-weekly regimen. These results suggest efficacy of Atu027 and warrant further investigation with Atu027 added to standard of care in APC. Clinical trial information: NCT01808638.

Care Evaluation

Quality monitoring in medicine was a neglected field until the last two decades. Doctors traditionally did their best, but how good that was could not be evaluated. This situation remains in some areas of medicine, but specialties with clearly-defined interventions and outcomes have progressed in quality of care evaluation, and cardiac surgery leads the way. Measuring the risk of an intervention allows prediction of the outcome and is essential for quality monitoring: without knowing the predicted outcome, the actual outcome cannot be evaluated. Cardiac surgery risk models like EuroSCORE and others have been adopted worldwide, so that measuring risk-adjusted performance is now an integral part of the delivery of good cardiac surgical care. When mortality for a procedure is higher for one surgeon (or hospital) than another, this can be due to one of three reasons, or a combination of the three: the difference is due to chance, or variation in risk profile, or better and safer service. We now have the tools to distinguish between the above factors. We can also observe performance over time: cusum curves plot the performance of surgeons and hospitals by showing hypothetical ‘lives saved’. This provides early warning of deterioration in performance before a problem reaches statistical significance. With the appropriate tools, it is possible not only to identify a problem, but also to anticipate and thus prevent a problem from happening. Monitoring clinical performance is an exciting and rewarding field for future development, and one that will yield real improvements in patient outcomes.

Effect sizes are critical to result interpretation and synthesis across studies. Although statistical significance testing has historically dominated the determination of result importance, modern views emphasize the role of effect sizes and confidence intervals. This article accessibly discusses how to calculate and interpret the effect sizes that counseling psychologists use most frequently. To provide context, the author presents a brief history of statistical significance tests. Second, the author discusses the difference between statistical, practical, and clinical significance. Third, the author reviews and graphically demonstrates two common types of effect sizes, commenting on multivariate and corrected effect sizes. Fourth, the author emphasizes meta-analytic thinking and the potential role of confidence intervals around effect sizes. Finally, the author gives a hypothetical example of how to report and potentially interpret some effect sizes.

The present study focuses on determining the difference among the levels of emotional maturity and self- concept of low, moderate and high users of internet. Two dimensions of emotional maturity have been studied in the research viz-a-viz Emotional Instability and Personality Disintegration. For the purpose of the study, a sample of 100 participants were selected which consisted primarily of students between the age group of 17-24, considering the fact that an individual’s personality has been shaped and the self-concept of individuals in this age group may/may-not be affected due to external variables. After the data collection, the results showed that low internet users will have lower emotional instability, lower chances of personality disintegration and lower self-concept. Moderate users were seen to be having a positive correlation between Emotional instability and Personality Disintegration and negative correlation with respect to self- concept and High users of Internet were seen to be having Higher Emotional Instability, Lower personality Disintegration and Low self-concept. Mean, Standard deviation and Pearson Product movement correlation was used to analyze data and bar graphs and line graphs were used to interpret data.

<p class="Style2">To be able to achieve good corporate governance, in addition to managerial ownership, institutional ownership and board of directors, the role of the audit committee also needed to further enhance the quality of information contained in the financial statements in accordance with his duties. Good corporate governance is one way to address the practice of earnings management. Study to examine the effect of the mechanisms of good corporate governance on earnings management that uses the data in the Indonesian capital market, still very little is done. Earnings management is a management action in the process of preparing financial statements to influence the level of profit that is displayed. The goal is to improve the welfare of certain parties, which can be identified as an advantage. Earnings management problem is the agency problem that is often triggered by a separation of the role or the difference between the interests of the owners (shareholders) with managing the company's management.</p>

Background Epilepsy affects 1% of children worldwide. The highest incidence is in the first year of life, and perinatal factors, such as hypoxic-ischemic injury, infection, and cortical malformation may play etiologic roles. Breast milk contains optimal nutrients for human brain in early life. Breastfeeding has been associated with lower risk of infections, better cognitive and psychomotor development. However, the role of breastfeeding in preventing childhood epilepsy remains unclear. Objective To evaluate an association between exclusive breastfeeding and childhood epilepsy. Methods A case-control study conducted from 1 May to 3 July 2013 involving children with epilepsy aged 6 months to 18 years who were attending pediatric outpatient clinic of Dr. Sardjito Hospital, Yogyakarta. Neurologically normal children, individually matched by age and sex, visiting the same clinic were considered as controls. Exclusion criteria were children with structural brain abnormality, history of epilepsy in family, and who had history of neonatal seizure, intracranial infection, febrile seizure, and head trauma before onset of epilepsy. History of breastfeeding was obtained by interviewing the parents. The difference of exclusively breastfeeding proportion between cases and controls was analyzed by McNemar test. Results The total number of participants was 68 cases and controls each. Subjects with epilepsy had lower proportion of exclusively breastfed (48.5%) compared with controls (54.4%), but the difference was not statistically significant (P=0.541). Exclusively breastfeeding showed no statistical significance in decreasing risk of epilepsy (OR=0.71; 95%CI 0.32 to 1.61). Conclusions Exclusive breastfeeding for 4-6 months has no effect against childhood epilepsy.
