Corrupção e escândalo político: o enquadramento dos escândalos face oculta e mensalão na imprensa portuguesa e brasileira
Authors: Prior Hélder , Guazina Liziane , Araújo Bruno 
Published: July 2015

O artigo que o leitor tem entre mãos é uma tentativa de analisar a coberturajornalística de dois escândalos de corrupção, o Face Oculta e o Mensalão, numaperspetiva comparativa. Versando, num primeiro momento, sobre os fenómenos dacorrupção e do escândalo político, procuraremos analisar os conceitos à luz da Filosofia Política, discorrendo sobre a sua relação sem, contudo, deixar de fazer a sua distinção analítica. Na parte empírica, adotaremos a teoria do enquadramento no sentido de compreender de que forma o semanário SOL (Portugal) e a Revista Veja (Brasil), operaram uma reconfiguração dos escândalos no momento da sua eclosão.
Anatomia do comentário: corrupção, noticiários e destinatários
Authors: Figueiras Rita 
Published: July 2015

No âmbito dos estudos sobre a corrupção e os media, este estudo tem dois grandes objetivos: identificar o modo como os comentadores nos noticiários da televisão generalista abordam dois dos casos de corrupção mais mediatizados nos últimos anos em Portugal (os casos Freeport e Face Oculta), relacionando as narrativas jornalísticas e as dos comentários, e conhecer a forma como os comentadores se posicionam no debate público e entendem a sua função no processo comunicativo democrático. Para os comentadores os casos foram mais sobre estratégia e desempenho dos atores e das instituições envolvidas do que sobre o crime da corrupção. A definição dos problemas, as interpretações causais e recomendações foram construídas a partir do establishment, onde os conflitos internos dentro de cada uma das esferas implicadas nos casos, e entre as várias esferas, foram transpostos para os comentários; ainda que alguns comentadores tenham articulado o processo horizontal de comunicação intra, e interelite, e o vertical dirigido ao público em geral. O estudo de ambos os casos permitiu verificar que o espaço de opinião continua a subsistir como um setor dominado pelas elites dirigentes na sociedade portuguesa, que comunica principalmente para si própria e que se mantém com uma capacidadeelevada de imunidade à evolução do contexto social e mediático. A análiseda narrativa do comentário revelou‑se, assim, um local privilegiado para identificar e compreender como as lutas sociais de poder são travadas no espaço público.

En la actualidad, una de las formas más directas por la que los niños acceden a la tecnología digital es mediante los videojuegos. Este aspecto no suele ser considerado en entornos educativos en la adquisición de Competencias Básicas. Sin embargo, existen informes internacionales que valoran la potencialidad de los videojuegos como recurso educativo. En este sentido, desde el 2006, el Informe Horizon incluye los videojuegos educativos como una tecnología con repercusión en la enseñanza, el aprendizaje y la expresión creativa dentro de los entornos educativos. En este mismo informe, a partir del 2012 las Tabletas Digitales son consideradas como una de las tecnologías con mayor posibilidad de ser de uso generalizado en educación a corto plazo. Por otro lado, existen estudios que relacionan mayor interés de alumnos en carreras de ciencia, arte y tecnología al uso prematuro de herramientas de modelado o impresión 3D. En este artículo queremos poner en valor dos aplicaciones, Blokify y Pottery, disponibles para tabletas digitales, que funcionan como juegos y que introducen al alumno en el modelado y la impresión tridimensional digital.
Implications of sodium hydrogen exchangers in various brain diseases
Authors: Verma Vivek , Bali Anjana , Singh Nirmal , Jaggi Amteshwar Singh 
Published: July 2015

Abstract
Na+/H+ exchangers (NHEs) are the transporter proteins that play an important role in intracellular pH (pHi) regulation, cell differentiation and cell volume and that mediate transepithelial Na+ and HCO3
− absorption on the basis of chemical gradients across the plasma membrane. Its activation causes an increase in intracellular Na+, which further leads to Ca+ overload and cell death. The pharmacological inhibition of these transporter proteins prevents myocardial infarction and other heart diseases like congestive heart failure in experimental animal models as well as in clinical situations. The more recent studies have implicated the role of these exchangers in the pathophysiology of brain diseases. Out of nine NHE isoforms, NHE-1 is the major isoform present in the brain and regulates the trans-cellular ion transport through blood-brain barrier membrane, and alteration in their function leads to severe brain abnormalities. NHEs were shown to be involved in pathophysiologies of many brain diseases like epilepsy, Alzheimer’s disease, neuropathic pain and ischemia/reperfusion-induced cerebral injury. Na+/H+-exchanger inhibitors (e.g., amiloride and cariporide) produce protective effects on ischemia/reperfusion-induced brain injury (e.g., stroke), exhibit good antiepileptic potential and attenuate neuropathic pain in various animal models. The present review focuses on the pathophysiological role of these ion exchangers in different brain diseases with possible mechanisms.

Published: July 2015

AbstractTransient tachypnea of the newborn (TTN) results from inadequate neonatal lung fluid clearance. Low-dose dopamine induces natriuresis in the kidneys and it has been assumed that, at this low dosage, dopamine increases renal perfusion in critically ill patients. Medium doses have positive inotropic and chronotropic effects via increased β-receptor activation. Recent studies have demonstrated that dopamine stimulates the clearance of pulmonary edema. Furthermore, β-adrenergic agonists regulate NaA prospective controlled study examined 60 infants with TTN older than 34 weeks of gestation who required at least 24 h of OThe requirement for mechanical ventilation, and durations of nCPAP, oxygen requirement, and hospitalization did not differ significantly among the three groups (P=0.54, 0.16 and 0.11, respectively).Dopamine treatment in low-moderate doses does not improve the outcome in TTN. Thus, further studies in this area are needed.

Published: July 2015

AbstractAssessments of generic indices of health in wildlife populations increase our knowledge about the natural history of animal species and provide useful information for ecoepidemiological studies. However, there have been minimal studies on the parameters of hematological and biochemical parameters in wildlife. The goal of this study was to evaluate physiological dynamics of wild capybaras (
Topological Complexity in Protein Structures
Authors: Flapan Erica , Heller Gabriella 
Published: July 2015

Abstract
For DNA molecules, topological complexity occurs exclusively as the result of knotting or linking of
the polynucleotide backbone. By contrast, while a few knots and links have been found within the polypeptide
backbones of some protein structures, non-planarity can also result from the connectivity between a
polypeptide chain and inter- and intra-chain linking via cofactors and disulfide bonds. In this article, we survey
the known types of knots, links, and non-planar graphs in protein structures with and without including
such bonds and cofactors. Then we present new examples of protein structures containing Möbius ladders
and other non-planar graphs as a result of these cofactors. Finally, we propose hypothetical structures illustrating
specific disulfide connectivities that would result in the key ring link, the Whitehead link and the 51
knot, the latter two of which have thus far not been identified within protein structures.
Surface magneto plasmons and their applications in the infrared frequencies
Authors: Hu Bin , Zhang Ying , Wang Qi Jie 
Published: July 2015

Abstract
Due to their promising properties, surface magneto plasmons have attracted great
interests in the field of plasmonics recently. Apart from flexible modulation of
the plasmonic properties by an external magnetic field, surface magneto plasmons
also promise nonreciprocal effect and multi-bands of propagation, which can be
applied into the design of integrated plasmonic devices for biosensing and
telecommunication applications. In the visible frequencies, because it demands
extremely strong magnetic fields for the manipulation of metallic plasmonic
materials, nano-devices consisting of metals and magnetic materials based on
surface magneto plasmon are difficult to be realized due to the challenges in
device fabrication and high losses. In the infrared frequencies, highly-doped
semiconductors can replace metals, owning to the lower incident wave frequencies
and lower plasma frequencies. The required magnetic field is also low, which
makes the tunable devices based on surface magneto plasmons more practically to
be realized. Furthermore, a promising 2D material-graphene shows great potential
in infrared magnetic plasmonics. In this paper, we review the magneto plasmonics
in the infrared frequencies with a focus on device designs and applications. We
investigate surface magneto plasmons propagating in different structures,
including plane surface structures and slot waveguides. Based on the fundamental
investigation and theoretical studies, we illustrate various magneto plasmonic
micro/nano devices in the infrared, such as tunable waveguides, filters, and
beam-splitters. Novel plasmonic devices such as one-way waveguides and
broad-band waveguides are also introduced.

Published: July 2015

AbstractCarbon dots (CDs) are a recently discovered class of fluorescent nanomaterials with great potential to be applied in the analytical field. CDs have demonstrated to be a promising alternative to conventional organic fluorophores or quantum dots as optical nanoprobes for sensing different chemical species. In this overview, we review the progress in the design of novel nanoprobes based on fluorescent CDs for inorganic trace analysis. Representative examples of CD-based assays are described and the different sensing strategies are discussed.
Nursing Steps to Prevent Surgery-Related Pressure Ulcers in Patients Undergoing Combined Hysteroscopy and Laparoscopy: A Double-Blind, Randomized, and Controlled Trial
Authors: Fu Dong Ying 
Published: July 2015

OBJECTIVE To evaluate the preventive effect of perioperative nursing interventions on acute pressure ulcer in patients undergoing combined hysteroscopy and laparoscopy.

METHODS A total of 144 patients who undergoing combined hysteroscopy and laparoscopy were randomly divided into an experimental group and a control group. The patients of the experiment were implemented by new interventions throughout the perioperative period. The patients in the control were provided only routine care. Assessment for skin integrity and pressure ulcer risk factors carried out during three periods. The outcomes including the patients’ feedback, the incidence and the stage of pressure ulcer were collected.

RESULTS The incidence of pressure ulcer in the experiment was significantly less than that in the control group. The experimental group was placed in positions that they were able to tolerate comfortably. The score of their satisfaction is significantly higher than those in the control group. The patients of both groups developed stage I pressure sores, but no statistical difference.

CONCLUSION The nursing interventions of the experiment can be considered as an effective method of decreasing the incidence of pressure ulcer in patients undergoing combined hysteroscopy and laparoscopy. Those strategies that start in the preadmission areas and continue through the intraoperative to postoperative periods can have a noticeable impact on patient’s outcomes.
Propeller Perforator Flaps in Hand Reconstruction: The effect of blood vessel twisting
Authors: Ardelean Filip , Muntean Maximilian , Dumitrascu Dinu , Strilciuc Stefan , Georgescu Alexandru Valentin 
Published: July 2015

Background and aims. Perforator flaps increasingly find acceptance and use in hand reconstructive surgery. A propeller flap is an island flap that moves from one orientation to another by rotating around its vascular pedicle. It is now possible to design propeller flaps based on a single perforator, so-called "perforator-based propeller flaps," but they are more prone to vascular impairment when twisted more than 90°.Methods. We present a prospective study conducted in the Plastic and Reconstructive Surgery Department of the Rehabilitation Hospital over 17 months. All perforator-based propeller flaps that were used for hand reconstruction were analyzed. The parameters studied included the size and location of the defect, the size and shape of the flap, the perforator (length and location) that was used, the degree of twisting of the perforator, the degree of perforator dissection, the management of the donor site, and flap survival area.Results. In this study we investigated the circulatory impairment induced by twisting of the pedicle on a true perforator flap. All flaps survived completely with the exception of partial skin necrosis in few cases. Some of these cases required debridement and skin grafting.Conclusions. Perforator-based propeller flaps provide a reliable option for covering small- to medium-size hand complex tissue defects. They have the advantages of using similar tissues in reconstruction, not damaging another area, they do not require main vessels sacrifice, and the donor site can be generally directly closed.

Published: July 2015

BACKGROUND AND AIMS. The incidence of rectal cancer in the European Union is about 35% of the total colorectal cancer incidence. Staging rectal cancer is important for planning treatment. It is essential for the management of rectal cancer to have adequate preoperative imaging, because accurate staging can influence the therapeutic strategy, type of resection, and candidacy for neoadjuvant therapy. The aim of this work is to evaluate the accuracy of endorectal ultrasound (ERUS) in rectal cancer staging.METHODS. A retrospective study was performed to assess the accuracy of ERUS by analyzing patients discharged from Regional Institute of Gastroenterology and Hepatology (IRGH) Cluj-Napoca, Romania, diagnosed with rectal cancer between 01 January 2011 and 31 December 2013. Patients who were preoperatively staged by other imaging methods and those who had ERUS performed in another service were excluded from the analysis. As inclusion criteria remained ERUS performed for patients with rectal cancer in IRGH Cluj-Napoca where they were also operated. We analyzed preoperative T stage obtained by ERUS and it was compared with the histopathology findings.RESULTS. The number of patients discharged with a diagnosis of rectal cancer were 200 (operated – 157) in 2011, 193 (operated – 151) in 2012, and 198 (operated – 142) in 2013. We analyzed a total of 51 cases diagnosed with rectal cancer who performed ERUS in IRGH Cluj-Napoca. The results according to the T stage obtained by ERUS and histopathology test were:Under-stage T2= 25.0%, T3=7.9% of cases;Over-stage T2=25.0%, T3=31.6% and T4=60.0% of cases.Less than 20% of patients underwent preoperative radio-chemotherapy.CONCLUSIONS. ERUS is a method of staging rectal cancer which is human dependent. ERUS is less accurate for T staging of stenotic tumours, but the accuracy may still be within acceptable limits. Surgeons use ERUS to adopt a treatment protocol, knowing the risk of under-staging and over-staging of this method. The accuracy of ERUS is higher in diagnosing rectal cancer in stages T1, T2 and even in stage T3 with malignant tumor which is not occlusive. ERUS is less accurate for T staging of locally advanced and stenotic tumours.
Anxiety and IBS Revisited : ten years later
Authors: Popa Stefan-Lucian , Dumitrascu Dan Lucian 
Published: July 2015

BACKGROUND AND AIM: Irritable bowel syndrome (IBS) has been associated with high prevalence of psychological and psychiatric disorders. However, the association between IBS and each of its subtypes ( diarrhea IBS-D, constipation IBS-C, mixed IBS-M) with anxiety, still remains unclear. The purpose of this study was to perform a comparative analysis, of the association between anxiety and IBS on a period of ten years.METHODS: PubMed was searched for studies analyzing IBS and anxiety, published at 10 years interval. The study presents a comparative analysis of the articles that were published between 2003-2005 and 2013-2015, investigating the correlation between anxiety and IBS.RESULTS: The initial search identified 220 articles, from which 156 were published between 2013 and 2015, and 64 were published between 2003 and 2005. Of these articles, 15 articles were included in the review. Out of these 15 articles, 10 articles analyzed the correlation between anxiety-depression status in IBS patients using specific questionnaires, 2 articles analyzed genetic variables in IBS, 1 article analyzed serom and monoamine oxidase levels in IBS, 1 article have analyzed seric levels of IL-1β and IL-10 in IBS, 1 article analyzed somatostatin and vasoactive intestinal peptide levels in IBS. The result was a review of 15 studies that analyzed the association between IBS and anxiety.CONCLUSIONS : IBS is a heterogeneous disorder caused by numerous psychological, immunological, infectious, endocrine and genetic factors. In recent years, the number of studies concentrating on genetic factors, cytokines and hormones has increased in comparison with the 2003-2005 period, when clinical investigation, using mainly questionnaires was the essential method. Also, the total number of papers investigating anxiety and IBS, considerably increased. The recent studies have confirmed the fact that IBS symptoms are often exacerbated during stressful events and the psychiatric treatment has a positive effect on gastro-intestinal symptomatology.

<p><strong>RESUMO</strong></p><p><strong>Introdução:</strong> O presente estudo refere-se a um processo de investigação sobre a representação social dos enfermeiros sobre cuidados paliativos. Objetivos: identificar a estrutura das representações sociais dos enfermeiros sobre cuidados paliativos; discutir as repercussões dessas representações no cotidiano da prática assistencial. <strong>Materiais e Métodos:</strong> Para a realização deste estudo foram abordados 70 enfermeiros que atuam nas enfermarias do serviço de Clínica Médica. A técnica para coleta de dados foi a da evocação livre. Para este estudo o termo indutor foi cuidado paliativo, e foi solicitada a associação de cinco palavras aos participantes do estudo. O material foi, então, tratado pelo software Ensemble de programmes permettant l’analyse dês evocations (EVOC). <strong>Resultados e</strong> <strong>Discussão: </strong>O sistema central é homogêneo, possui forte teor negativo e fornece estabilidade a representação. Por outro lado, a presença de elementos positivos no sistema periférico como carinho, conforto, dedicação e humanização reforçam o caráter flexível da representação. Cabe ressaltar que o provável núcleo central é pouco sensível ao contexto imediato, o que significa afirmar que, mesmo que o mais utópico dos setores de cuidados paliativos fosse inaugurado neste momento, o núcleo central da representação dos cuidados paliativos para enfermeiros não se modificaria imediatamente. <strong>Conclusões:</strong> Apesar dos cuidados paliativos e suas tecnologias estarem cada vez mais presentes no cotidiano hospitalar e, portanto, serem alvo de constantes debates em veículos de comunicação, a sua representação social, elaborada por este grupo de enfermeiros, permanece com forte teor negativo. </p><p><strong><em>Cómo citar este artículo:</em></strong><em> Britto S, Ramos R, Santos É, Veloso O, Silva M, Silva A Mariz R</em><em>. </em><em>Representação social dos enfermeiros sobre cuidados paliativos.<strong> </strong></em><em>Rev Cuid. 2015; 6(2): 1062-9.</em><em> </em><a href="http://dx.doi.org/10.15649/cuidarte.v6i2.170"><em>http://dx.doi.org/10.15649/cuidarte.v6i2.170</em></a><em></em></p>
