Inclusão no Ensino Superior: Perceções dos estudantes com Necessidades Educativas Especiais sobre o ingresso à universidade
Authors: Santos Evelyn , Gonçalves Manuela , Ramos Isabel , Castro Lisneti , Lomeo Roselane
Published: July 2016

A educação inclusiva no Ensino Superior representa atualmente um desafio de âmbito social, educacional e político, que nos move a uma reflexão sobre o ingresso de estudantes com Necessidades Educativas Especiais (NEE) no Ensino Superior em Portugal. A fim de conhecer os principais suportes referenciados como essenciais para a inclusão optou-se pelo paradigma da investigação interpretativa com cariz qualitativo, sendo a recolha de dados através de entrevista semiestruturada. Foi verificada a importância de vários suportes, em especial o da família. O contingente especial para acesso ao Ensino Superior foi referenciado por todos os estudantes como um importante apoio. A forma como a universidade se organiza na fase de ingresso foi considerada satisfatória; no entanto, apresenta aspetos pontuais a serem modificados. As acessibilidades físicas/estruturais e culturais/atitudinais são citadas como fundamentais para a permanência destes estudantes na Universidade de Aveiro; porém, a falta de respaldo legal e de políticas inclusivas nacionais ainda dificultam esse processo.

A Növekedési Hitelprogram gazdaságélénkítő hatásai
Authors: Quittner Péter
Published: July 2016

Jelen tanulmány a Magyar Nemzeti Bank által 2013 nyarán elindított Növekedési Hitelprogram (NHP) gazdaságélénkítő hatásait vizsgálja, elsősorban a GDP-re összpontosítva rövid- és középtávon. Mivel hasonló eszköz alkalmazására Magyarországon még nem volt példa, a hatékonyságára vonatkozó hazai szakirodalom is erősen hiányos. Ebből adódóan az eredmények viszonyítási alapját az ezekkel az eszközökkel kapcsolatos külföldi tapasztalatok adják, amelyek viszonylag hatékonynak tekintik ezeket az intézkedéseket. A jelen tanulmányban bemutatott empirikus elemzés Magyarország esetében is alátámasztja ezeket az állításokat, ugyanis az eredmények alapján az NHP mind az aggregált keresletre, mind pedig a potenciális kibocsátásra szignifikánsan pozitív hatást gyakorolhat. Ugyanakkor a program következményeképp megfigyelhető egy aszimmetrikus intertemporális átváltás is, így hosszabb távon megjelenik egy negatív hatás, amely azonban jelentősen elmarad az azt megelőzően jelentkező gazdaságélénkítő hatás mértékétől.

Stabil párosítások a gyakorlatban
Authors: Petróczy Dóra Gréta
Published: July 2016

A könyv szerzője, Alvin E. Roth, a Stanford Egyetemen professzora 2012-ben a stabil párosítások és a piactervezés területén elért eredményeiért Lloyd S. Shapley-vel közösen Nobel-emlékdíjat kapott. Míg Shapley-nek inkább elméleti munkája különleges, addig Roth a párosítások gyakorlati alkalmazásának terén alkotott igazán kiemelkedőt. Legújabb könyvének célja, hogy könnyed formában, közérthetően ismertesse meg az olvasót a piactervezéssel. Nem szakmabeliek számára is élvezetesen, történeteken, alkalmazásokon keresztül mutatja be eddigi munkáit, a könyv végére mégis olyan elméleti fogalmakkal is megismerkedünk, mint a Gale-Shapley algoritmus vagy a stabil párosítások. Ugyanakkor nagyon személyes könyv is, a szerző saját történeteivel színesíti a leírtakat. Megismerhetjük, hogyan vált elméleti szakemberből gyakorlati szakértővé, miként találkozott a megoldásra váró problémákkal, milyen szervezetek és miért kérték a segítségét, illetve fordítva, miként vette rá a döntéshozókat, hogy megfontolják a tanácsait. Szintén olvashatunk azokról a bürokratikus, politikai akadályokról, amelyek nehezítették a munkáját.
The influence of the position of the medial portal and of lower leg flexion on the length of the femoral tunnel in anatomic anterior cruciate ligament reconstruction: A cadaveric study

Published: July 2016

Background/Aim. The key to successful anterior cruciate ligament reconstruction lies in the proper positioning of the femoral tunnel within the anatomical footprint and in providing for an adequate length of this tunnel without perforation to the lateral cortex. The aim of this study was to determine the change in the length of the femoral tunnel drilled during anatomic anterior cruciate ligament (ACL) reconstruction, depending on: the position of the limb being operated on, the degree of knee flexion, as well as the angle between the drill and the medial aspect of the lateral condyle. Methods. This study was performed on 16 cadaveric knees (6 male and 10 female) of the average age of 83. After the subcutaneous tissue was dissected, the femoral insertion of the ACL was identified. Then, 18 tunnels were drilled through the center of the femoral insertion with the help of 2 mm thick Kirschner wires. This was performed in two stages. In the first phase the leg was positioned on an arthroscopic leg holder, while in the second phase the leg was positioned on the table. In each phase the knee was placed in three different flexion positions (110?, 120? and 130?) and for each position three tunnels were drilled (70?, 60? and 50?) in relation to the medial aspect of the lateral condyle. Results. The average length of the femoral tunnel drilled with the leg positioned on the operating table (36.6 ? 4.7 mm) was highly statistically significantly greater (p = 0.000) in comparison with the length of the femoral tunnel obtained by positioning the leg on a fixed arthroscopic leg holder (35.4?4.3 mm). The greatest lengths of the femoral tunnel were obtain with the leg flexed at 130? and the reamer positioned at 50? angle in relation to the medial aspect of the lateral condyle (43 mm on the operating table and 41 mm on a fixed leg holder), while the shortest tunnel (33 mm on the operating table and 31 mm on a fixed leg holder) was obtained with the lower leg flexed at 110? and the reamer positioned at a 70? angle. Conclusion. The optimal position of the leg on a fixed leg holder for obtaining a femoral tunnel of sufficient length requires lower leg flexion of 120? and the position of the medial portal which enables the positioning of the reamer at a 60? angle in relation to the medial aspect of the lateral condyle. With the leg positioned on the operating table, it becomes unnecessary to push the leg into flexion greater than 110?; rather a longer femoral tunnel is achieved by lateralization of the medial portal.
Metabolomic Profile of Low–Copy Number Carriers at the Salivary α-Amylase Gene Suggests a Metabolic Shift Toward Lipid-Based Energy Production

Published: July 2016

Low serum salivary amylase levels have been associated with a range of metabolic abnormalities, including obesity and insulin resistance. We recently suggested that a low copy number at the AMY1 gene, associated with lower enzyme levels, also increases susceptibility to obesity. To advance our understanding of the effect of AMY1 copy number variation on metabolism, we compared the metabolomic signatures of high– and low–copy number carriers. We analyzed, using mass spectrometry and nuclear magnetic resonance (NMR), the sera of healthy normal-weight women carrying either low–AMY1 copies (LAs: four or fewer copies; n = 50) or high–AMY1 copies (HAs: eight or more copies; n = 50). Best-fitting multivariate models (empirical P < 1 × 10−3) of mass spectrometry and NMR data were concordant in showing differences in lipid metabolism between the two groups. In particular, LA carriers showed lower levels of long- and medium-chain fatty acids, and higher levels of dicarboxylic fatty acids and 2-hydroxybutyrate (a known marker of glucose malabsorption). Taken together, these observations suggest increased metabolic reliance on fatty acids in LA carriers through β- and ω-oxidation and reduced cellular glucose uptake with consequent diversion of acetyl-CoA into ketogenesis. Our observations are in line with previously reported delayed glucose uptake in LA carriers after starch consumption. Further functional studies are needed to extrapolate from our findings to implications for biochemical pathways.

Authors:   The Writing Group for the DCCT/EDIC Research Group
Published: July 2016

OBJECTIVE

The Diabetes Control and Complications Trial (DCCT)/Epidemiology of Diabetes Interventions and Complications (EDIC) study has demonstrated the beneficial effect of intensive therapy on atherosclerosis and clinical cardiovascular outcomes, while identifying hyperglycemia as a dominant risk factor for type 1 diabetes. The current analyses evaluate the extent to which glycemic exposure influences long-term changes in established risk factors for cardiovascular disease (CVD) among patients with type 1 diabetes.

RESEARCH DESIGN AND METHODS

The DCCT study randomized 1,441 participants to receive intensive or conventional diabetes therapy; and after an average of 6.5 years of follow-up, 96% of the surviving cohort enrolled in the EDIC observational study for an additional 20 years of follow-up. Annual visits included a detailed medical history and physical examination. Blood and urine samples were collected and assayed centrally. Longitudinal models for repeated measurements were used.

RESULTS

Higher HbA1c level was a significant correlate of the longitudinal changes in all of the traditional CVD risk factors over the 30-year follow-up. The strongest longitudinal associations were among the lipid measurements and concurrent glycemia.

CONCLUSIONS

A better understanding of the interrelationships between diabetes-related risk factors and traditional CVD risk factors may assist with the development of targeted treatment regimens for persons with type 1 diabetes who are at risk for CVD.
Specific Blood Pressure Targets for Patients With Diabetic Nephropathy?
Authors: Grassi Guido , Mancia Giuseppe , Nilsson Peter M.
Published: July 2016

Diabetic nephropathy represents a condition frequently detected in current clinical practice characterized by a very high cardiovascular risk profile. Blood pressure reduction via antihypertension drug treatment represents a therapeutic approach capable of exerting favorable effects on renal and cardiovascular outcomes. The purpose of this article is to review the current literature and results of key clinical trials pertaining to blood pressure goals of antihypertension treatment in these patients. The pros and cons of a less or a more intensive blood pressure goal in diabetic nephropathy will be discussed, with particular emphasis on the cardiovascular and renal effects of each therapeutic strategy.
Analyses of Results From Cardiovascular Safety Trials With DPP-4 Inhibitors: Cardiovascular Outcomes, Predefined Safety Outcomes, and Pooled Analysis and Meta-analysis
Authors: Mannucci Edoardo , Mosenzon Ofri , Avogaro Angelo
Published: July 2016

The U.S. Food and Drug Administration requires that the cardiovascular (CV) safety of all new drugs for diabetes be demonstrated through pooled analyses of phase III studies or specifically designed trials. This requirement prompted several placebo-controlled, noninferiority CV safety trials in high-risk patients; to date, all completed trials showed that dipeptidyl peptidase (DPP)-4 inhibitors do not increase or reduce the risk of major CV events. These results apparently contrast with those of pooled analyses and meta-analyses of previous, smaller trials with metabolic end points, which had suggested a reduction of risk. However, the design of CV trials, which were required to demonstrate safety, is not adequate (for duration, management of concurrent therapies, etc.) for the assessment of potential therapeutic benefits. In addition, CV safety trials enroll patients at high risk of CV events, who are different from those included in earlier trials with metabolic end points. Differences in characteristics of patients enrolled probably account for most of the discrepancy in CV outcomes between CV safety studies and earlier trials. The availability of several large-scale trials with longer duration provides the unique opportunity for assessment of the safety of DPP-4 inhibitors not only with respect to major CV events but also with reference to other safety issues. For example, CV safety trials can be a source of information for pancreatitis, cancer, or hypoglycemia.

Published: July 2016

The U.S. Food and Drug Administration (FDA) issued guidance on requirements to assess cardiovascular disease (CVD) risk with drugs being developed for approval for clinical use. The guidance was triggered by a meta-analysis published by Nissen and Wolski that suggested an increased risk for myocardial infarction with the use of rosiglitazone. This article discusses controversies around CVD trials in diabetes beginning with the University Group Diabetes Program. This is followed by a brief description of the FDA guidance for evaluating CVD risk with glucose-lowering medications. Limitations of meta-analyses of data from phase 2 and 3 (phase 2/3) trials to inform CVD risk are highlighted. These include the differences between patient characteristics in phase 2/3 trials and those in cardiovascular outcome trials (CVOTs) and the relatively short exposure time in phase 2/3 trials. The differences may partly explain the observed disparity between phase 2/3 meta-analyses and the results of completed CVOTs. Approaches to understanding CVD risk with a new medication should get to the answer about risk as efficiently as possible to minimize any potential harm to patients. In that context, we discuss options for clinical trial design and an alternative approach for statistical analyses.

Published: July 2016

CASE DESCRIPTION Within a 2-week period, 4 southern cassowaries (Casuarius casuarius) at an exhibit at a Virginia zoo died acutely subsequent to eastern equine encephalitis virus (EEEV) infection. This prompted a search for other EEEV outbreaks in cassowaries, which resulted in the identification of 2 additional cassowaries that died of EEEV infection at a conservation center in Florida.

CLINICAL FINDINGS Both juvenile and adult birds were affected. Three of the 6 birds died acutely with no premonitory signs. Clinical disease in the other 3 birds was characterized by lethargy and ataxia. Clinicopathologic findings typically included leukocytosis, hyperuricemia, abnormally high liver enzyme activities, and hyper–β globulinemia, which was indicative of acute inflammation.

TREATMENT AND OUTCOME The 3 birds with clinical disease died despite supportive treatment. Gross abnormalities commonly observed during necropsy included coelomitis and evidence of diarrhea. Frequently observed histologic abnormalities were encephalitis, vasculitis, hepatitis, nephritis, and splenitis. The diagnosis of EEEV infection was confirmed by detection of serum anti-EEEV antibodies or detection of viral RNA in brain tissue by use of a reverse-transcriptase PCR assay.

CLINICAL RELEVANCE Findings suggested that EEEV can cause high morbidity and mortality rates in southern cassowaries. Clinical disease might be reduced or prevented by vaccination, isolation of ill birds, and mosquito control strategies.
Dry sliding wear behavior of aluminum graphene nanoplatelet (GNP) composites
Authors: Istif Ilyas , Tuncel Mehmet Tunc
Published: July 2016

Conventional aluminum (Al) and its alloys have been replaced by aluminum matrix composites (AMCs) due to their superior properties in the recent years. There are several attractive candidates as reinforcement for aluminum composites such as Al2O3, B4C and SiC. Nowadays, carbon based materials such as graphite, carbon nanotubes (CNTs) and graphene have attracted much attention owing to their above mentioned mechanical and physical properties. In this study, the wear behavior of Al graphene nanoplatelets (GNPs) composites reinforced with up to 2 wt.-% GNP were investigated. The addition of graphene up to 1 wt.-% decreased coefficient of friction. Experimental data were used to develop linear and nonlinear models. The experimental results are in good agreement with the results of the simulations based on the identified models.

Kurzfassung

Stumpfschweißverbindungen austenitischer Werkstoffe sind häufig Teil von Komponenten der Kraftwerkstechnik oder des chemischen Apparatebaus. In diesem Bereich unterliegen die Bauteile zyklischen mechanischen und thermischen Lasten. Vornehmlich bedingt durch hohe Temperaturschwingweiten, resultieren hohe elastisch-plastische Dehnungsschwingweiten. Die Bereiche Grundmaterial und Schweißnaht zeigen ein unterschiedliches plastisches Deformationsverhalten, die daraus resultierende metallurgische Kerbe kann versagensmaßgebend sein. Im Rahmen der begleitenden numerischen Untersuchungen wurde ein Modell entwickelt, um die metallurgische Kerbe abzubilden.
Electrical properties of a high voltage aluminum electrolytic capacitor with anode foil
Authors: Bo Qiu Xiao
Published: July 2016

Among all the raw materials for aluminum electrolytic capacitors, there is no doubt that the anode foil is one of the most important raw materials influencing the performance of capacitors. The voltage, capacitance, thickness and impurity content of the anode foil have a direct effect on the performance of capacitor. The cost of anodes also contributes to the total cost of capacitors by a high percentage. Thus, for the manufacturers of capacitors, minimizing the anode foil costs needs also to be taken into account besides its performance. Against such a background, this article evaluates the anode foil of a new supplier to be used in a 400 V medium and in a high voltage aluminum electrolytic capacitor with the purpose of minimizing the product costs while achieving the same performance. The capacitors with new supplier's anode foil are compared with that using the current anode foil by evaluating the performance by the change of the various electrical properties.
Prediction of machinability of AA7075 using artificial neural networks
Authors: Kaya Hasan , Ekinci Önder
Published: July 2016

In this study, machinability behavior of AA7075 aged at different time lengths was examined experimentally and by using artificial neural network prediction model. The hardness values were measured after the heat treatment processes. Homogenized reference samples and aged samples were machined by turning processes. On the one hand, the wear occurring on the cutting edge during machining, and the cutting forces depending on cutting speed and surface roughness were investigated. Surface roughness values for each reference material and aged sample were measured using processing parameters. Acquired surface roughness values formed a surface roughness prediction model by using artificial neural networks. The results showed that the surface roughness of the samples decreases while the cutting speed of the lathe increases. In the prediction model formed by using surface roughness acquired after the machinability tests, cutting force, cutting speed and aging process were used as input parameters. Surface roughness as a result of machinability tests were used as output parameters of the proposed prediction model. High coefficient of determination, R2 rate, obtained in the formed prediction model showed that the model is successful in the prediction of surface roughness.

Perioperative Acute Kidney Injury in Cardiac Surgery
Authors: Khan Sayedur R , Kabir Jahangir
Published: July 2016

Acute kidney injury (AKI) is a relatively common complication, occurs in up to 30% of all patients in cardiac surgery and requires dialysis in approximately 2% of patients. The development of AKI after cardiac surgery is associated with increased morbidity and mortality. AKI is caused by a variety of factors, including nephrotoxins, hypoxia, mechanical trauma, inflammation, cardiopulmonary bypass and hemodynamic instability and it may be affected by the clinicians choice of fluids and vasoactive agents as well as the transfusion strategy used. More timely diagnosis would allow for earlier intervention and could improve patient outcomes. Currently, there are no active treatments for AKI. Therefore, In-depth knowledge of the risk factors and pathogenesis for AKI offers some guidance for the prevention and management of AKI.Bangladesh Heart Journal 2015; 30(2) : 78-86
