Ektopinė (heterotopinė) kasa plonosios žarnos pasaite: klinikinio atvejo pristatymas ir literatūros apžvalga
Authors: Navickas Gediminas , Valančienė Dileta 
Published: July 2016

Ektopinė kasa (EK) – reta įgimta anomalija, kai normalus kasos audinys yra už kasos ribų. Heterotopinis kasos audinys plonosios žarnos pasaite yra ypač retai sutinkamas EK tipas. EK dažniausiai aptinkama įvairiose virškinamojo trakto dalyse atsitiktinai.
Paprastai EK yra simptomų nesukelianti anomalija, tačiau kliniškai gali pasireikšti atsiradus komplikacijoms, tokioms kaip uždegimas, kraujavimas, obstrukcija ar supiktybėjus. Simptomų išsivystymas priklauso nuo EK dydžio, lokalizacijos bei patologinių audinio pokyčių, kurie taip pat būdingi ir normaliam kasos audiniui. Operacinis gydymas nėra indikuotinas, nebent esant komplikacijoms, todėl labai svarbi tiksli priešoperacinė diagnozė siekiant išvengti nereikalingų intervencijų.
Mes pristatome retą klinikinį atvejį, kada EK lokalizavosi plonosios žarnos pasaite. Pateikiame paciento kompiuterinės tomografijos tyrimo vaizdus. Šis klinikinis atvejis parodo, kad ektopinis kasos audinys visada turėtų būti įtrauktas į gastrointestinių navikų diferencinę diagnostiką.
Selfie y la impronta visual: el autorretrato 3.0 representación, presentación, corporealización
Authors: Rabadán Crespo Angel V. 
Published: July 2016

<p>El presente artículo propone una reflexión sobre el <em>selfie</em>, no sólo para la presentación de la persona en los contextos sociales de interacción, sino también como práctica socio-técnica creativa, lúdica o auto-reflexiva sobre sí, el cuerpo y la identidad personal a través del dispositivo móvil. Esta práctica de autorretrato, vinculada generalmente a la narrativa cotidiana personal pasa a ser, a través de internet, una práctica pública que puede tener una amplia audiencia. En este sentido, podría entenderse también como una nueva forma cultural de presentación social de sí, que conllevaría un trabajo de <em>performación</em> de la identidad personal de un modo relacional, ya sea como una actuación pública del yo o como resultado de una práctica performativa sobre el propio cuerpo. </p>

<p>El poder de la imagen es uno de los principales motores de cambio que se ha dado en la prensa con la aparición de internet y la evolución de las TIC. El presente estudio analiza cómo es la estructura que está utilizando la prensa digital y qué papel representa la publicidad respecto a los elementos textuales e icónicos que forman el periódico. El trabajo cuantifica y compara el papel de la imagen y la publicidad en las cabeceras online consideradas <em>nativas</em>, es decir aquellas que han nacido en la red, con las procedentes de un soporte impreso. El análisis revela que los diarios on-line nativos presentan mayor volumen publicitario en detrimento del contenido informativo. Al mismo tiempo se constata una mayor presencia de la información gráfica en los primeros. En conjunto puede afirmarse que el componte visual domina las portadas de ambos tipos de diarios digitales, si bien en los diarios nativos digitales este efecto está más agudizado.</p><h2><em>Abstract</em></h2><p>Visual strength is responsible for one of the mayor changes undergone by the digital press with Internet explosion and the increase of the Informational and Communicational Technologies. The present study analyzes the structure the digital press has taken and the role of the digital advertisement in the composition of their textual and iconic elements. The paper quantifies the picture representations volume and compares their presence on the digital natives papers with those coming from the traditional paper support. The results reveal that there is a mayor contribution of adverts on the native on-line press compare to the on-line paper arriving from the traditional media decreasing the information volume. At the same time the visual volume is boosted on the former compare to the digital media with a paper support. Altogether it can be said that visual component prompted the digital papers first page, being this effect enhanced on the native digital papers. </p><p> </p>

Influence of output power of a spin torque oscillator on phase locked loop operation
Authors: Tamaru Shingo , Kubota Hitoshi , Yakushiji Kay , Fukushima Akio , Yuasa Shinji 
Published: August 2016

Abstract
This work investigates the influence of the output power of a spin torque oscillator (STO) on the operation of a phase locked loop (PLL) circuit. Timing jitter and minimum output power for stable PLL operation determined by Johnson noise and shot noise are first theoretically calculated, and compared with experimental results. The theory and experiment show a reasonably good agreement, indicating that smaller than −50 dBm (10 nW), or −60 dBm (1 nW) when a low pass filter is used, of output power is sufficient for stable PLL operation if a large timing jitter is acceptable. However, it is also shown that a large output power is needed to suppress timing jitter down to the level comparable to state-of-the-art commercial PLL circuits. The estimate of minimum output power for stable PLL operation is verified by intentionally attenuating the STO output signal down to −55 dBm (3.2 nW) and demonstrating a stable phase locked oscillation.
A physically based analytical model of flood frequency curves
Authors: Basso S. , Schirmer M. , Botter G. 
Published: August 2016

AbstractPredicting magnitude and frequency of floods is a key issue in hydrology, with implications in many fields ranging from river science and geomorphology to the insurance industry. In this paper, a novel physically based approach is proposed to estimate the recurrence intervals of seasonal flow maxima. The method links the extremal distribution of streamflows to the stochastic dynamics of daily discharge, providing an analytical expression of the seasonal flood frequency curve. The parameters involved in the formulation embody climate and landscape attributes of the contributing catchment and can be estimated from daily rainfall and streamflow data. Only one parameter, which is linked to the antecedent wetness condition in the watershed, needs to be calibrated on the observed maxima. The performance of the method is discussed through a set of applications in four rivers featuring heterogeneous daily flow regimes. The model provides reliable estimates of seasonal maximum flows in different climatic settings and is able to capture diverse shapes of flood frequency curves emerging in erratic and persistent flow regimes. The proposed method exploits experimental information on the full range of discharges experienced by rivers. As a consequence, model performances do not deteriorate when the magnitude of events with return times longer than the available sample size is estimated. The approach provides a framework for the prediction of floods based on short data series of rainfall and daily streamflows that may be especially valuable in data scarce regions of the world.
Multifrequency seismic detectability of seasonal thermoclines assessed from ARGO data
Authors: Ker S. , Le Gonidec Y. , Marié L. 
Published: August 2016

AbstractSeismic oceanography is a developing research topic where new acoustic methods allow high‐resolution teledetection of the thermohaline structure of the ocean. First implementations to study the Ocean Surface Boundary Layer have recently been achieved but remain very challenging due to the weakness and shallowness of such seismic reflectors. In this article, we develop a multifrequency seismic analysis of hydrographic data sets collected in a seasonally stratified midlatitude shelf by ARGO network floats to assess the detectability issue of shallow thermoclines. This analysis, for which sensitivity to the data reduction scheme used by ARGO floats for the transmission of the profiles is discussed, allows characterizing both the depth location and the frequency dependency of the dominant reflective feature of such complex structures. This approach provides the first statistical distribution of the range of variability of the frequency‐dependent seismic reflection amplitude of the midlatitude seasonal thermoclines. We introduce a new parameter to quantify the overall capability of a multichannel seismic setup, including the source strength, the fold, and the ambient noise level, to detect shallow thermoclines. Seismic source signals are approximated by Ricker wavelets, providing quantitative guidelines to help in the design of seismic experiments targeting such oceanic reflectors. For shallow midlatitude seasonal thermoclines, we show that the detectability is optimal for seismic peak frequencies between 200 and 400 Hz: this means that airgun and Sparker sources are not well suited and that significant improvements of source devices will be necessary before seismic imaging of OSBL structures can be reliably attempted.
Investigating Predictors of Superior Face Recognition Ability in Police Super‐recognisers
Authors: Davis Josh P. , Lander Karen , Evans Ray , Jansari Ashok 
Published: August 2016

SummaryThere are large individual differences in the ability to recognise faces. Super‐recognisers are exceptionally good at face memory tasks. In London, a small specialist pool of police officers (also labelled ‘super‐recognisers’ by the Metropolitan Police Service) annually makes 1000's of suspect identifications from closed‐circuit television footage. Some suspects are disguised, have not been encountered recently or are depicted in poor quality images. Across tests measuring familiar face recognition, unfamiliar face memory and unfamiliar face matching, the accuracy of members of this specialist police pool was approximately equal to a group of non‐police super‐recognisers. Both groups were more accurate than matched control members of the public. No reliable relationships were found between the face processing tests and object recognition. Within each group, however, there were large performance variations across tests, and this research has implications for the deployment of police worldwide in operations requiring officers with superior face processing ability.

Published: August 2016

ObjectiveTo identify empirical model‐based patterns of multimorbidity from chronic noncommunicable diseases in the general population, with a focus on the contribution of rheumatic and musculoskeletal diseases (RMDs), and to quantify their association with adverse health outcomes.MethodsCross‐sectional data from the Portuguese Fourth National Health Survey were analyzed (n = 23,754). Latent class analysis was used to identify patterns of coexistence of 11 chronic noncommunicable diseases (RMDs, diabetes mellitus, hypertension, chronic obstructive pulmonary disease, stroke, depression, myocardial infarction, cancer, osteoporosis, asthma, and renal failure). Based on the Outcome Measures in Rheumatology, filter 2.0, health outcomes included life impact, pathophysiologic manifestations, and resource use. We assessed the association between patterns and adverse health outcomes, through sex‐, age‐, and body mass index–adjusted prevalence ratios with 95% confidence intervals, obtained using Poisson regression.ResultsFour patterns of chronic noncommunicable diseases co‐occurrence were identified and labeled as low disease probability, cardiometabolic conditions, respiratory conditions, and RMDs and depression. RMDs were highly prevalent in patients with chronic diseases (from 38.6% in cardiometabolic conditions to 66.7% in RMDs and depression). While negative self‐rated health, short‐term disability, and chronic pain were more strongly associated with cardiometabolic conditions and respiratory conditions, all multimorbidity patterns were similarly associated with long‐term disability, frequent health care utilization, and out‐of‐pocket health care expenses.ConclusionOur study emphasizes RMDs as a major presence in multimorbidity in the general population. All multimorbidity patterns were associated with a wide set of adverse health outcomes. Management strategies for the patient with chronic cardiometabolic, respiratory, or depressive conditions should also target RMDs.

Published: August 2016

ObjectiveComorbidity among cancer patients poses additional risks for mortality. The possible impact of rheumatoid arthritis (RA) on cancer patient survival is unclear. Our objective was to examine survival among elderly patients with RA who develop cancer.MethodsPatients diagnosed with breast, prostate, colorectal, or lung cancer between 2001 and 2010 were identified from the Texas Cancer Registry and Medicare–linked databases. The cohort was categorized into 3 groups according to the number of claims patients had with a diagnosis of RA in the year prior to the cancer diagnosis: 2‐RA (patients with ≥2 claims), 1‐RA (1 claim), and no claims. Overall survival was estimated for these groups and for each cancer, using Cox proportional hazards models adjusting for covariates.ResultsThe cohort included 139,097 patients with cancer (35,026 breast, 43,181 prostate, 31,103 colorectal, and 29,787 lung); 1.7% had 1 RA claim, and 1.1% had 2 or more. Adjusted hazard ratios for patients in the 2‐RA group were 1.41 (95% confidence interval [95% CI] 1.21–1.65) for breast and 1.53 (95% CI 1.26–1.85) for prostate. No significant differences were observed for those with colorectal or lung cancer.ConclusionMortality was increased by 40% and 50%, respectively, in elderly patients with RA who developed breast or prostate cancer, after controlling for other comorbidities. This association was not seen in cancers with shorter survival time (colorectal or lung). Research is needed to determine whether the increased risk is related to comorbid burden or to differential utilization of cancer or rheumatoid therapies in patients with both diseases.

ObjectiveTo determine associations between magnetic resonance imaging (MRI) lesions originating from either axial spondyloarthritis (SpA) or from degeneration and pain in patients with chronic back pain of <2 years duration.MethodsPatients from the Spondyloarthritis Caught Early (SPACE) cohort identified the sites of pain (thoracic, lumbar, buttock). The average MRI scores from 2 readers for axial SpA lesions and from 2 different readers for degenerative lesions were used. Associations between sacroiliac (SI) joint lesions and buttock pain were investigated by logistic regression analysis, and associations between axial SpA or degenerative lesions and pain in the spine (thoracic and lumbar) were investigated using generalized estimating equations. Interactions with sex, age, HLA–B27, and fulfillment of Assessment of SpondyloArthritis international Society (ASAS) criteria were tested.ResultsIn 348 patients (126 males, 127 fulfilling ASAS criteria, mean age 29.4 years), spinal MRI (and SI joint images in 342) were available. Pain was localized in the thoracic spine (35.9%), the lumbar spine (82.5%), or in the buttock(s) (57.8%). Inflammatory lesions of the SI joint (odds ratio [OR] 1.06; P = 0.04) and erosions of the SI joint in patients <25 years (OR 1.16; P = 0.04) were associated with buttock pain. Axial SpA spinal lesions were not associated with pain. Modic type 1 lesions in patients >35 years (OR 5.19; P = 0.001), high‐intensity zone lesions in females not fulfilling ASAS criteria (OR 5.09; P = 0.001), and herniation in various subgroups (OR range 2.07–4.66) were associated with pain.ConclusionSpecific degenerative lesions, but not typical axial SpA lesions, of the spine are associated with pain at the same location in some subgroups. Inflammatory lesions in the SI joint are associated with buttock pain.
Diastereo‐ and Enantioselective Construction of Dihydroisocoumarin‐Based Spirooxindole Frameworks via Organocatalytic Tandem Reactions

Published: August 2016

AbstractAn organocatalytic asymmetric approach has been developed for the ennantioselective construction of dihydroisocoumarin‐based spirooxindole frameworks in high yields, excellent diastereo‐ and enantioselectivities (up to 99%, all >95:5 dr, up to 99% ee). This approach takes advantage of chiral thiourea‐tertiaryamine catalyzed tandem reaction of isatins with enolizable homophthalic anhydride, which has wide substrate scope and can be performed with low catalyst loading. This reaction not only provides an efficient and useful method for constructing enantioenriched dihydroisocoumarin‐based spirooxindole scaffold, but also will enrich the research contents of catalytic asymmetric tandem reactions and enantioselective synthesis of biologically important spirooxindoles.magnified image
Ruthenium‐Mediated Dual Catalytic Reactions of Isoquinoline via C−H Activation and Dearomatization for Isoquinolone
Authors: Wang Ting‐Hsuan , Lee Wei‐Chih , Ong Tiow‐Gan 
Published: August 2016

AbstractWe have unraveled the ruthenium‐promoted prototype reaction based on C(sp2)−C(sp3) bond formation through the reigoselective C−H activation of isoquinoline and pyridine derivatives with various alkyl halides, leading to 1‐substituted isoquinoline products in good yield. This C−H catalytic reaction did not rely on chelation assistance of the directing group of the substrates. The dimer [RuCl2(p‐cymene)]2 in combination with an N‐heterocyclic carbene ligand, adamantanecarboxylic acid and K2CO3 base in N‐methyl‐2‐pyrrolidone solution at 150 °C are the best conditions. Simultaneously, we are also able to chemically tune the reaction mode to dearomatization by adding water, leading to isoquinolone products. This reaction methodology is not suitable for other nitrogen‐containing heteroarenes such as pyridazines and pyrimidines.magnified image
