Published: April 2015

AbstractA surgical swab retained in the body after surgery is known as ′Gossypiboma′. The purpose of this report is to highlight an intramural vesical gossypiboma mimicking an invasive adnexal malignancy. A 28-year-old multiparous, with open-tubal ligation three years ago, presented with painless hematuria and a nontender mass on vaginal examination. USG suggested ′pelvic endometriosis′ infiltrating into the bladder and cystoscopy showed no intraluminal extension of the mass. Contrast-enhanced computed tomography (CECT) and magnetic resonance imaging (MRI) misdiagnosed it as invasive malignancy of the fallopian tube. Exploratory laparotomy found it to be an intramural vesical gossypiboma. A pelvic gossypiboma infiltrating into the wall of the urinary bladder may easily be misinterpreted as an invasive pelvic malignancy on imaging and may make one consider unwarranted radical surgery.

Published: April 2015

Background Arterial calcium as measured by 64-slice computed tomography coronary angiography (64-CT) is a reliable predictor of cardiovascular disease risk. Lipid-rich plaques with lower degrees of calcification may pose greater risk for adverse coronary events than more stabilized calcified plaques as a result of the increased risk of plaque rupture, migration, and subsequent acute coronary syndrome. We sought to examine coronary artery calcium scores as measured via 64-CT to assess the extent of calcification and plaque distribution in women compared to men. Methods A total of 138 patients referred for 64-CT were evaluated. Computerized tomographic angiography was performed using the GE LightSpeed VCT. Subgroup analysis comparing male and female data (including demographic data) was performed. All major coronary arteries were analyzed for coronary stenosis/plaque characterization as well as total vessel calcium (Agatston) score quantification. Patient demographics and coronary risk factors were recorded. Results A total of 552 coronary arteries were evaluated in 138 patients (85 men, 53 women). The average age for females was 64.4 ± 10.8 years and for males 60.0 ± 12.8 years. The only demographic/cardiovascular risk factor in which the difference between men and women was significant was smoking history, where 23.5% of men had a history of smoking while only 9.6% of females endorsed having a smoking history ( P < 0.044). On comparison of all total vessel calcium scores, males had a higher total mean calcium score than females in each individual vessel. The results were as follows for males versus females, respectively: left main total vessel calcium score 46.49 versus 16.71 ( P = 0.167); left anterior descending 265.21 versus 109.6 ( P < 0.003); left circumflex 130.5 versus 39.7 ( P < 0.004); and right coronary 213.5 versus 73.8 ( P < 0.01). The odds of having a total calcium score >100 (versus not) was 3.62 times greater in males relative to females, given that all the other cardiovascular risk factors are adjusted for (95% confidence interval: 1.37-9.54). On average, men had an average of 2.1 ± 1.5 epicardial vessels with a calcium score ≥11 compared to 1.3 ± 1.4 for women ( P < 0.005). Conclusion There are clear differences between males and females regarding total vessel calcium scores and therefore risk of future adverse coronary events. Males tended to have higher average calcium scores in each coronary artery than females with a greater tendency to have multiple vessel involvement. Using this information, more large-scale, randomized controlled studies should be performed to correlate differences in the extent of coronary calcification with the observed variance in clinical presentation during coronary events between males and females as a means to potentially establish gender-specific therapeutic regimens.

Objectives Outcomes of catheter ablation of atrial fibrillation (AF) vary widely. We used late-gadolinium enhancement MRI (LGE-MRI) to examine the relationship of ablation-induced scarring in the pulmonary vein (PV) region and overall atrium to evaluate the role of PV encirclement and substrate modification in predicting outcome of catheter ablation in AF. Methods and Results LGE-MRI was performed to quantify baseline atrial fibrosis, which was classified into four stages (stage I with fibrosis <10%, stage II with fibrosis 10-20%, stage III with fibrosis 20-30%, and stage IV with fibrosis >30%). Patients then underwent ablation and repeat LGE-MRI at three months to assess for ablation-induced scarring. PVs were studied to evaluate for complete encirclement with scar. Image processing was used to overlay the scar onto baseline fibrosis to assess the overlap and calculate residual fibrosis. A total of 172 patients were included with an average baseline fibrosis of 14.6 ± 8.4%. The average number of PVs encircled with scar at three months was 1.2 ± 1.3 with only 9% of patients having all four PVs completely encircled. The average residual fibrosis was 11.9 ± 7.3%. High residual fibrosis was defined as >10%. Recurrent AF was found in 60 patients (34.9%) over a follow-up of 346 ± 82 days. Baseline and high residual fibrosis were significant predictors of recurrence (hazard ratio [HR] of 2.2; P < 0.01 and HR of 3.2; P < 0.01, respectively). The number of PV encircled was not a significant predictor of recurrence. Conclusion LGE-MRI of ablation-induced scarring demonstrates that chronic PV encirclement is rarely achieved. Procedural outcomes are better predicted by baseline atrial fibrosis and ablation-induced substrate modification.

Tyrimai atlikti LAMMC Sodininkystės ir daržininkystės instituto Augalų fiziologijos laboratorijos fitotrono komplekse ir instituto daigyno šiltnamyje. Darbo tikslas – parinkti naujų puslaidininkinių lempų fotonų srauto tankį auginat agurkų daigus šiltnamiuose ir fitotrone. Tyrimams naudotas agurkų hibridas ‘Mandy’ F<sub>1</sub>. Švitinta LED lempomis, kurios sudarytos iš violetinės 420–430 nm, mėlynos 460– 470 nm, oranžinės 610–615 nm, raudonos 620–630 nm ir 660–670 nm, baltos (mėlyna 400–500 nm + žalia 500–600 nm + raudona 600–700 nm) spalvos šviesą emituojančių diodų. Eksperimentų metu palaikytas skirtingas fotosintetiškai aktyvios spinduliuotės (FAS) fotonų srauto tankis (PPFD) – ~150 ir ~250 µmol m<sup>–2</sup> s<sup>–1</sup>. Šiltnamyje agurkų daigai auginti po puslaidininkinėmis lempomis natūralaus apšvietimo fone. Fitotrono kamerose agurkų daigams apšviesti naudotos tik puslaidininkinės lempos. Palyginamieji daigai auginti po aukšto slėgio natrio lempomis (SON-T Agro) (~150 µmol m<sup>–2</sup> s<sup>–1</sup>). Atlikti apšvietimo tyrimai šiltnamyje ir fitotrone parodė, kad švitinimas naujomis puslaidininkinėmis lempomis turėjo teigiamos įtakos daigų biometriniams ir fitocheminiams rodikliams. Nustatyta, kad esant didesniam fotonų srauto tankiui daigai geba užauginti plačius lapus, sukaupti daugiau žalios ir sausos masės. Puslaidininkinių lempų šviesa skatino chlorofilų kaupimą daigų lapuose. Šiltnamyje labiausiai išsivystė daigai, augę po SON-T Agro lempomis. Techninės brandos tarpsniu jie pasiekė VI–VII organogenezės etapą. Fitotrone labiausiai išsivystė daigai, augę po puslaidininkinių lempų šviesa, jie pasiekė VI organogenezės etapą. Daigų fotosintezės intensyvumui didžiausios teigiamos įtakos turėjo ~150 µmol m<sup>–2</sup> s<sup>–1</sup> LED apšvietimo fotonų srauto tankis tiek šiltnamyje, tiek fitotrone.

Darbe tirtas azoto trąšų poveikis skirtingų žieminių kviečių veislių fotosintetinių rodiklių dinamikai. Lauko eksperimentas vykdytas 2012–2013 m. Aleksandro Stulginskio universiteto Bandymų stotyje, karbonatingame sekliai glėjiškame išplautžemyje <i>Calc(ar)i-Epihypogleyic Luvisol</i>. Tyrimo objektas – gerų kepimo savybių žieminių kviečių veislės ‘Kovas’, ‘Olivin’. Sėjos metu kviečiai buvo tręšti vienanarėmis fosforo, kalio trąšomis (P<sub>60</sub>K<sub>60</sub>), o pavasarį, atsinaujinus vegetacijai, – amonio salietra (N<sub>60</sub>). Papildomai per lapus tręšti karbamido tirpalu (N<sub>30</sub>, N<sub>40</sub>) bamblėjimo ir (N<sub>15</sub>, N<sub>30</sub>) pieninės brandos tarpsniais. Tyrimų metu nustatyta, kad papildomas tręšimas N<sub>30</sub> ir N<sub>40</sub> azoto normomis vėlyvaisiais augalo vystymosi tarpsniais skatino fotosintezės pigmentų kaupimąsi ir prailgino aktyvios fotosintezės periodą. Veislės genetiniai ypatumai turėjo įtakos pigmentų kau­pimuisi nepriklausomai nuo tręšimo azoto trąšomis. Gerų kepimo savybių kviečių veislė ‘Kovas’ linkusi kaupti didesnius fotosintezės pigmentų kiekius. Didžiau­sias pig­mentų kiekis nustatytas pieninės brandos pradžioje prieš papildomą tręši­mą N<sub>15</sub>, N<sub>30</sub> trąšų normomis. ‘Olivin’ veislės žieminiai kvie­čiai turi didesnį grynąjį fotosintezės produktyvumo potencialą nei ‘Kovas’ veis­lės kviečiai. Intensyviausiai ‘Olivin’ veislės augalų fotosintezė vyko nuo vamzdelėji­mo iki pieninės brandos tarpsnio (BBCH 43–74), tręšiant N<sub>60</sub> + N<sub>40</sub>, o ‘Kovas’ veislės kviečių – N<sub>60</sub> + N<sub>30</sub> azoto normomis.
A multi-factor model of panic disorder: Results of a preliminary study integrating the role of perfectionism, stress, physiological anxiety and anxiety sensitivity
Authors: Wood Cristina Mae , Cano-Vindel Antonio , Salguero José Martín 
Published: April 2015

<p><strong>Background:</strong> Panic disorder (PD) is a highly prevalent and disabling mental health problem associated with different factors including perfectionism, stress, physiological anxiety, and anxiety sensitivity regarding physical concerns; however, no studies have analyzed the joint relationship between these factors and PD in a multi-factor model using structural equation modeling. <strong>Method: </strong>A cross-sectional study was carried out to collect data on these factors and self-reported DSM-IV past-year PD symptoms in a large sample of the general population (<em>N</em>=936). <strong>Results:</strong> Perceived stress had a significant effect in increasing physiological anxiety, which in turn had an important association with physical concerns. Perfectionism and perceived stress had an indirect relation with past year PD via the mediator role of physiological anxiety and physical concerns. Physical concerns, on one hand, seemed to mediate the impact between perfectionism and PD and, on the other, partially mediated the role between physiological anxiety and PD. <strong>Conclusions: </strong>Although there is considerable evidence on the association between each of these factors and PD, this model can be considered a broader and productive framework of research on the nature and treatment of PD.<strong></strong></p>
Entre le droit canonique et la grâce papale. Étude de leurs rapports dans le cas d’une supplique adressée

à la Pénitencerie apostolique
Authors: Ballard Alexia 
Published: April 2015

Pourquoi l’avancement d’une carrière ecclésiastique, au début du XVe siècle, peut-il nécessiter l’octroi de dispenses? C’est à partir de cette problématique que nous entendons analyser une supplication adressée par Gilles Vrieleghem à la Pénitencerie apostolique en date du 16 mai 1411. Cette lettre est rédigée à la suite du concile pisan lors de la déposition des deux autres pontifes, Pedro de Luna et Angelo Correr et de l’élection d’un nouveau pape, Martin V. Le changement d’obédience de son diocèse force l’impétrant à s’adresser à la Pénitencerie pour s’assurer de la validité de ses dispenses précédemment reçues et pour garantir la jouissance sereine de ses bénéfices.
L’usage de l’expression « peut nécessiter » est une nuance importante. Tous les candidats pour la cléricature ne doivent pas être forcément dispensés s’ils ne contreviennent pas au droit canon. Ce « flottement », qui implique un certain risque pour l’impétrant de perdre le contrôle de ses bénéfices, sera étudié à travers le cas de Gilles Vrieleghem. Ce dernier est considéré comme irrégulier à cause de sa naissance illégitime. Nous allons éclairer, avec l’exemple de ce prêtre et d’autres clercs, la nécessité pour toute personne irrégulière en vertu du droit canon d’obtenir des dispenses. Celles-ci deviennent obligatoires si le candidat souhaite accéder à la cléricature ou gravir les échelons hiérarchiques.
Le peuplement initial des Antilles
Authors: Perrot-Minnot Sébastien 
Published: April 2015

Si l’on excepte le cas de l’île de Trinidad, en raison de son caractère continental, les occupations humaines les plus anciennes des Antilles ont été découvertes dans les Grandes Antilles. Elles datent d’une période qui a été qualifiée de « Lithique » ou de « Paléoindienne », dans le système chrono-culturel conçu par Irving Rouse, mais que nous avons préféré désigner sous le nom d’Archaïque Ancien (6500-4000 BP). Leur matériel archéologique a été rattaché, par Rouse, à la tradition Casimiroïde. Il comprend un outillage de pierre qui a suscité des comparaisons avec des complexes archaïques du Belize et du nord-ouest du Venezuela ; il nous semble que les analogies entre les industries macrolaminaires du Belize et des Antilles sont particulièrement significatives, et qu’elles pourraient désigner le lieu d’origine des premiers Antillais. Les raisons qui ont pu pousser des groupes humains à coloniser l’archipel sont difficiles à déterminer, mais sont sans doute à rechercher dans les bouleversements économiques et sociaux qui ont affecté les sociétés de la période Archaïque. En tout cas, certains indices archéologiques font présumer que l’établissement de l’homme dans les Antilles s’est accompagné d’une rupture de l’ordre social en vigueur sur le continent, et de changements profonds et durables dans l’organisation des sociétés.
Global ionospheric response to the 2009 sudden stratospheric warming event using Ionospheric Data Assimilation Four‐Dimensional (IDA4D) algorithm

Published: April 2015

AbstractA data assimilation algorithm is used to delineate the time‐dependent three‐dimensional ionospheric response to the 2009 sudden stratospheric warming (SSW) event. We use the Ionospheric Data Assimilation Four‐Dimensional (IDA4D) algorithm to study the global ionospheric response to the 2009 SSW. This is the first study to utilize global ionospheric measurements in a data assimilation framework to unambiguously characterize atmosphere‐ionosphere coupling via tidal modifications during the 2009 SSW event. Model results reveal that the dominant mode of ionospheric variability during the 2009 SSW is driven by the enhancements in westward propagating semidiurnal tide with zonal wave number 1. The IDA4D results completely characterize the tidal perturbation during the 2009 SSW for the first time and show the global 3‐D structure of the tide in total electron content (TEC) and electron density. The largest ionospheric responses were seen at low latitudes, where ionospheric plasma is extremely sensitive to the zonal electric field and susceptible to modifications by tidal winds in the lower thermosphere. The ionospheric response to the warming was characterized by an increase in TEC in the morning/early afternoon sector and a decrease during the late afternoon/evening period. The effects of coupling between the stratosphere and ionosphere were strongest between 220 km and 380 km. The IDA4D results also show a reversal of asymmetry in the equatorial ionization anomaly crests occurring several days after the peak of the 2009 SSW event. We suggest that this could be a result of the equatorial fountain effect being further modified by the summer‐to‐winter meridional neutral winds.

AbstractIn this study, we apply a new method—the first‐order Taylor expansion (FOTE)—to find magnetic nulls and reconstruct magnetic field topology, in order to use it with the data from the forthcoming MMS mission. We compare this method with the previously used Poincare index (PI), and find that they are generally consistent, except that the PI method can only find a null inside the spacecraft (SC) tetrahedron, while the FOTE method can find a null both inside and outside the tetrahedron and also deduce its drift velocity. In addition, the FOTE method can (1) avoid limitations of the PI method such as data resolution, instrument uncertainty (Bz offset), and SC separation; (2) identify 3‐D null types (A, B, As, and Bs) and determine whether these types can degenerate into 2‐D (X and O); (3) reconstruct the magnetic field topology. We quantitatively test the accuracy of FOTE in positioning magnetic nulls and reconstructing field topology by using the data from 3‐D kinetic simulations. The influences of SC separation (0.05~1 di) and null‐SC distance (0~1 di) on the accuracy are both considered. We find that (1) for an isolated null, the method is accurate when the SC separation is smaller than 1 di, and the null‐SC distance is smaller than 0.25~0.5 di; (2) for a null pair, the accuracy is same as in the isolated‐null situation, except at the separator line, where the field is nonlinear. We define a parameter ξ ≡ |( λ1 + λ2 + λ3 )|/|λ|max in terms of the eigenvalues (λi) of the null to quantify the quality of our method—the smaller this parameter the better the results. Comparing to the previously used parameter (η≡|∇ ⋅ B|/|∇ × B|), ξ is more relevant for null identification. Using the new method, we reconstruct the magnetic field topology around a radial‐type null and a spiral‐type null, and find that the topologies are well consistent with those predicted in theory. We therefore suggest using this method to find magnetic nulls and reconstruct field topology with four‐point measurements, particularly from Cluster and the forthcoming MMS mission. For the MMS mission, this null‐finding algorithm can be used to trigger its burst‐mode measurements.
Fabrication Puts Suspects at Risk: Blindness to Changes in Transgression‐related Statements
Authors: Sauerland Melanie , Schell‐Leugers Jennifer Maria , Sagana Anna 
Published: April 2015

SummaryBased on the finding that deceptive and misleading interrogation techniques are not uncommon, we investigated to what extent participants may be blind to alterations introduced to their accounts of past transgressions. Drawing from the source‐monitoring framework, we hypothesized that participants' truthfulness and whether they had committed a transgression in the past (transgression history) would be predictive of blindness. When filling out a questionnaire about their past transgressions, 80 participants fabricated some of their answers. Prior to an interview 1 week later, two previously fabricated and two truthful answers were covertly altered by the experimenter. We found substantial blindness rates, and, as hypothesized, blindness was more pronounced for (1) fabricated than truthful responses and (2) alterations with transgression history compared with no transgression history. Possible consequences may include the creation of guilt presumption and increasing pressure to obtain a confession. Both can be hazardous for suspects and the legal decision‐making process.

Nail gun injuries treated in U.S emergency departments, 2006–2011: Not just a worker safety issue
Authors: Lipscomb Hester J. , Schoenfisch Ashley L. 
Published: April 2015

BackgroundNail guns increase productivity in residential building but with a corresponding increase in worker injuries. They are also easily accessible, at low cost, to consumers.MethodsData from the occupational supplement to the National Electronic Injury Surveillance System (NEISS‐Work) were used to calculate national estimates of work‐related injuries from nail guns between 2006 and 2011. These were compared to estimates of consumer injuries obtained through online access to the Consumer Product Safety Commission's (CPSC) NEISS data.ResultsApproximately 25,000 ED‐treated work‐related and consumer nail gun injuries were estimated each year. During the construction economy collapse, injuries among workers declined markedly, closely following patterns of reduced residential employment. Reduction in consumer injuries was much more modest.ConclusionsCurrent nail gun injury patterns suggest marked blurring of work and home exposures. A united effort of CPSC, NIOSH, and OSHA is warranted to address these preventable injuries. Am. J. Ind. Med. 58:880–885, 2015. © 2015 Wiley Periodicals, Inc.
