Published: March 2017

Background: In the UK, the majority of diagnostic upper gastrointestinal (UGI) endoscopies are a result of direct-to-test referral from the primary care physician. The diagnostic yield of these tests is relatively low, and the burden high on endoscopy services. Dual-focus magnification, high-definition endoscopy is expected to improve detection and classification of UGI mucosal lesions and also help minimize biopsies by allowing better targeting.Methods: This is a retrospective study of patients attending for direct-to-test UGI endoscopy from January 2015 to June 2015. The primary outcome of interest was the identification of significant pathology. Detection of significant pathology was modelled using logistic regression.Results: 500 procedures were included. The mean age of patients was 61.5 (±15.6) years; 60.8% of patients were female. Ninety-four gastroscopies were performed using dual-focus magnification high-definition endoscopy. Increasing age, male gender, type of endoscope, and type of operator were all identified as significant factors influencing the odds of detecting significant mucosal pathology. Use of dual-focus magnification, high-definition endoscopy was associated with an odds ratio of 1.87 (95%CI 1.11-3.12) favouring the detection of significant pathology. Subsequent analysis suggested that the increased detection of pathology during dual-focus magnification, high-definition endoscopy also influenced patient follow-up and led to a 3.0 fold (p=0.04) increase in the proportion of patients entered into an UGI endoscopic surveillance program.Conclusion: Dual-focus magnification, high-definition endoscopy improved the diagnostic yield for significant mucosal pathology in patients referred for direct-to-test endoscopy. If this finding is recapitulated elsewhere it will have substantial impact on the provision of UGI endoscopic services.

Background: Acute mesenteric ischaemia is a condition with a grim prognosis on conservative treatment. Endovascular revascularisation is a promising approach for some of these patients.Case report: We present the case of a 44-year-old woman with a history of severe arterial hypertension, left leg claudication, and overlooked symptoms of chronic mesenteric ischaemia for one year, who was admitted for severe abdominal pain for one week. Computed tomographic angiography (CTA) showed acute mesenteric ischaemia by occlusion of the coeliac trunk and the superior mesenteric artery (SMA), without bowel perforation. In addition, CTA showed tight left renal stenosis and left external iliac stenosis. We performed angioplasty with a stent of the SMA, followed by revascularisation of the left renal artery. On control injection, the SMA appeared re-occluded, requiring a second stent implantation and a loading dose of dual antiplatelet therapy, with a good final result. Subsequently, the clinical course was uneventful, with no need of surgical exploration; a second procedure was planned, aiming at iliac revascularisation. At one month, the patient was asymptomatic, with normal Doppler flow in the SMA. Angiographic control during iliac revascularisation procedure showed a permeable SMA with a good filling of the coeliac trunk territory. Because of the suspicion of fibro-muscular dysplasia as aetiology, coronary angiography and cerebral CTA were performed, in order to exclude other potential lesions.Conclusions: Endovascular revascularisation in AMI is a promising alternative to the surgical approach in patients presenting without bowel perforation. Nevertheless, its safety and many tactical details remain to be clarified. Existing networks for revascularisation in acute myocardial infarction may be useful for the implementation of this approach.Abbreviations: AMI: Acute Mesenteric Ischaemia; CTA: Computed Tomographic Angiography; ICU: Intensive Care Unit; SMA: Superior Mesenteric Artery; STEMI: ST-segment Elevation Myocardial Infarction.

Background & Aims: The mutations in the gene that encodes vitamin K epoxide reductase (VKOR) enzyme are responsible for low levels of vitamin K. The purpose of this study was to evaluate whether the presence of the VKORC1 -1639 G> A polymorphism is a risk factor for non-variceal upper gastrointestinal bleeding (UGIB) in patients without concomitant therapy with vitamin K antagonists.Methods: This case-control study comprised 163 consecutive patients diagnosed with UGIB and 178 controls, in whom the diagnosis of UGIB was excluded. The following data were recorded: age, gender, alcohol consumption, smoking, history of UGIB, nonsteroidal anti-inflammatory drugs (NSAIDs) or low-dose aspirin consumption. Genetic analysis included genotyping for the VKORC1 -1639 G>A polymorphism.Results: History of UGIB (OR 3.463, CI95% 1.463-8.198, p=0.005), smoking (OR 2.498, CI95% 1.358-4.597, p=0.003), alcohol consumption (OR 3.283, CI95% 1.796-6.000, p<0.001), use of NSAIDs (OR 4.542, CI95% 2.502-8.247, p<0.001) or of low-dose aspirin (OR 2.390, CI95% 1.326-4.310), and the VKORC1 -1639 G> A AA genotype (OR 1.364, CI95% 0.998-1.863, p=0.05) were associated with an increased risk of UGIB. The risk of UGIB was analyzed in patients with genotype AA who used aspirin or NSAIDs. The genotype AA has not kept its status of independent risk factor (p=0.3). In subjects with NSAIDs/aspirin therapy and genotype AA there was a two times higher chance of UGIB compared to those under NSAIDs/aspirin therapy alone (OR 7.6 vs. 3.6, p<0.001).Conclusion: Patients with non-variceal UGIB caused by the use of NSAIDs or low-dose aspirin are more frequent carriers of the VKORC1 -1639 G>A AA genotype, as compared to those without UGIB.

Abstract: Introduction and aim: To analyse the effect of crosslinking (CXL) on corneal epithelial healing. Patients and method: 39 keratoconus patients following CXL and 11 patients following PRK were enrolled in this study. 21, 45 and 69 hours after CXL and 16, 37 and 61 hours following PRK slitlamp photographs were taken using fluorescein staining and the size of the epithelial defect and the time of epithelial closure was determined. As the observation time-points differed in both groups, the size of the epithelial defect following PRK was calculated for the time points used for analysis of CXL patients. These data were compared using chi-quadrat test. Results: Following crosslinking, epithelial closure occured within 3, following PRK within 4 days. In the area of epithelial erosion 45 and 69 hours after CXL or PRK treatment statistically significant difference (p = 0.005 and p<0.001) was verified. Conclusion: Our results show beneficial effect of crosslinking on corneal epithelial healing. Orv. Hetil., 2017, 158(10), 376–379.
Defining Disability: Understandings of and Attitudes Towards Ableism and Disability
Authors: Friedman Carli , Owen Aleksa L. 
Published: March 2017

Disabled people, amidst political and social gains, continue to experience discrimination in multiple areas. Understanding how such discrimination, named here as ableism, operates is important and may require studying perspectives of people who do not claim a disability identity. Ableism may be expressed in a number of ways, and examining how a particular group, in this case siblings of disabled people, understand and value disability may contribute to overall understandings about how ableism works. Thus, the purpose of this study is to explore relationships between siblings of disabled people's broad societal understandings of disability and their attitudes towards it. In order to tease out this relationship further we have also examined factors that impact how people define disability. Using both social psychological and sociological approaches, we have contextualized individual attitudes as providing additional new information about social meanings of disability, and set this study's results against the larger backdrops of debates over meanings of disability within Disability Studies. In our research, participants revealed complex understandings of disability, but most often defined disability as preventing or slowing action, as an atypical function, a lack of independence, and as a socially constructed obstacle. Participants' unconscious (implicit) disability attitudes significantly related to their understandings of disability as lacking independence, impairment, and/or in relation to the norm, and their conscious (explicit) disability attitudes. Moreover, longer employment in a disability-related industry was correlated with defining disability as a general difference, rather than as slowing or limiting of tasks.

As an empowering antidote to the psychiatric system, this piece repossesses and plays with medical establishment language. It indexes the drugs and treatments for bipolar disorder I’ve tried over the course of twenty years and multiple psychiatric hospitalizations. Initially written after a series of inpatient stays in my late 20’s, I recently revised "Testament" after another inpatient intensive period to include new treatment trials and psych unit jargon.

<p>A atemoia, assim como todos os frutos climatéricos, apresenta uma elevada perecibilidade, tornando-se importante a adoção de técnicas pós-colheita. Este trabalho teve como objetivo avaliar o armazenamento de atemoias recobertas com filme PVC. Os frutos utilizados foram da variedade ‘Gefner’ apresentando-se em estado de maturação verde-maduro. Estes foram transferidos para o laboratório de Química de Alimentos do IFCE, submetidos à higienização e divididos nos devidos tratamentos. O primeiro tratamento constou no armazenamento de cinco frutos em bandejas de isopor recobertos com filme PVC. O segundo, do recobrimento individual dos frutos em filme PVC, sendo estes acondicionados em bandejas de isopor e os frutos do controle. Estes foram armazenados durante 8 dias. O delineamento utilizado foi o DIC em esquema fatorial 3x4 com quatro repetições de cinco frutos por parcela. A cada tempo de armazenamento foram avaliadas: perda de massa, sólidos solúveis, acidez titulável, Ratio, pH e índice de rachaduras. O uso de filme plástico reduz a perda de massa, porém retarda o amadurecimento de frutos de atemoia. As rachaduras estão diretamente associadas ao amadurecimento dos frutos, ao aumento dos teores de sólidos solúveis e possivelmente a cultivar avaliada. </p><p align="center"><strong><em>Storage of atemoyas (</em></strong><em>Annona squamosa<strong> x </strong>Annona cherimola<strong>) covered with PVC film</strong></em><strong><em></em></strong></p><p><strong>Abstract</strong><strong>: </strong>The atemoya, as well as all climacteric fruits, is highly perishable, becoming important to adopt post-harvest techniques. This work aimed to evaluate the atemoyas storage covered with plastic wrap. The fruits used were of the variety 'Gefner' presenting itself in a state of green-mature aging. These were transferred to the Food Chemistry Lab IFCE submitted to cleaning and divided in appropriate treatments. The first treatment consisted in five fruit storage in styrofoam trays covered with plastic wrap. The second, the individual coating of the fruits in PVC film, which are packed in styrofoam trays and control fruits. These were stored for 8 days. The design was the DIC in 3x4 factorial with four replicates of five fruits per plot. Each storage time were evaluated: weight loss, soluble solids, titratable acidity, ratio, pH and cracking index. The use of plastic film reduces the weight loss, however retards the ripening of atemoya fruit. The cracks are directly associated with fruit ripening, increased soluble solids and possibly the cultivar evaluated.</p>

Management of Severe Periodontal Abscesses Using a Laser and Light‐Emitting Diode Procedure Adjunctive to Scaling and Root Planing: A Case Series
Authors: Giannelli Marco , Materassi Fabrizio , Lorenzini Luca , Bani Daniele 
Published: March 2017

Introduction: The current literature reports different treatment procedures for periodontal abscesses mainly based on empiricism, but an evidence‐based treatment of choice is still lacking. This case series shows the favorable results of a multilaser/light‐emitting diode (LED) treatment, termed photoablative‐photodynamic (PAPD) laser/LED therapy, adjunctive to scaling and root planing (SRP) for the management of acute periodontal abscesses.Case Series: Six patients underwent photoablation of the contaminated gingival epithelium by diode laser (λ 810 nm), irradiation with a λ 405‐nm LED, SRP, and repeated photodynamic treatments with 0.3% methylene blue activated with a λ 635‐nm diode laser to achieve antiseptic and anti‐inflammatory effects. Clinical examination and cytofluorescent analysis were used to evaluate the effects of this combined treatment. Subjective pain/discomfort was scored by a visual analog scale and questionnaire.Conclusion: Within the limitations of this case series, the present results indicate that the described PAPD laser/LED treatment performed in adjunct to conventional SRP can be a valuable approach to the treatment of acute periodontal abscesses because it is capable of accelerating periodontal healing while avoiding the use of local or systemic antibiotics and flap surgery.

Published: March 2017

Tekst se bavi pitanjem identiteta u proznom opusu Judite Šalgo, što je jedna od centralnih tematskih preokupcija njenog književnog stvaralaštva. Problem identiteta razmatra se u kontekstu teorijskih promišljanja druge polovine 20. veka koja su destabilizovala ovaj pojam i dovela u pitanje njegove esencijalističke formulacije. Takođe, pokazuju se konesekvence ovog preokreta u umetnosti, pre svega kada se radi o formulaciji „ženskog autorstva”, za čije razumevanje konstitutivan postaje pojam roda. Na ovom teorijskom horizontu istražuje se razumevanje vlastititog spisateljskog identiteta Judite Šalgo, kao i neukorenjeni i hibridni identitet njenih likova. Analizom priče Irena ili o Marini ili o biografiji(autobiografija) ukazuje se na sofisticiranu igru identitetom koju Judita Šalgo sprovodi ukrštanjem biografskog i autobiografskog diskursa.
Pueblos arroceros en la cuenca del Cebollatí: asentamientos surgidos a partir de la instalación del cultivo de arroz
Authors: Martinez Susana , Mercedes María 
Published: March 2017

A partir de la segunda mitad del SXIX, la organización productiva de la explotación de arroz, en la cuenca baja del Cebollatí, dio origen a pueblos arroceros que se han desarrollado en constelaciones convergiendo en nodos calificados de segundo y tercer nivel, en un paisaje particular y atractivo, donde los aspectos culturales y naturales se combinan. Varios usos productivos han estado asociados a la estructuración del territorio, en donde la formulación de asentamientos concebidos para la producción y organizados en forma semiautónoma son parte sustantiva. El territorio es un proceso y un producto de prácticas individuales y grupales, en el que conviven un patrimonio arqueológico- cerritos de indios- , que apelan a las raíces y a los primeros habitantes de nuestro territorio, un paisaje natural de llanuras, esteros, lagunas y montes naturales, y el paisaje cultural generado por el cultivo e industrialización del arroz. Este trabajo se aborda desde la perspectiva territorial: soporte físico más construcción histórica.
Nonlinear Regression Analysis and System Stiffness Approach for Formation Integrity Test Interpretation
Authors: Moi Sonja , Carlsen Liv Almas , Skadsem Hans Joakim , Islam Aminul , Helstrup Ole Anders 
Published: March 2017

Abstract
After drilling out cement at the start of a new wellbore section, a formation integrity test is routinely performed to verify the integrity of the new formation and the cement at the casing shoe. Test results can have large impacts on the drilling operation, such as motivating remedial cementing operations, changing the drilling fluid mass density or the setting depth of casing strings. Interpretation of the test results are often made difficult for a number of reasons, including significant fluid losses to permeable formations, large friction pressure losses, compression of trapped air and unstable pump operation.
This paper presents a new supervisory system providing real-time test analysis and automated result interpretation of pressure integrity tests, leak-off tests and extended leak-off tests. Based on a minimum of preconfigured user input, the system covers all test phases, from pressurization, fracture propagation to shut-in and flowback. Rather than relying on computationally intensive modelling of downhole physics, regression techniques are applied to relate surface pressure to injected fluid volume, shut-in duration and volume or time in flowback.
System compliance and fluid leakage rates are determined prior to leak-off using a nonlinear regression model. The calibrated model is in turn used to generate prediction intervals for detecting leak-off and fracture pressures. Extended leak-off interpretation is based on the system stiffness approach, in which fracture closure is associated with a reduction in system compliance. We apply regression techniques to search for fracture closure during shut-in and during flowback. The system identifies unexpected test behavior and triggers warnings by continuously evaluating key test metrics such as leakage rate, system compliance and surface pressure during each test phase.
The development is based on few model assumptions. Low-pass filtering combined with regression techniques ensure that the system is capable of analyzing field tests of variable quality and with noisy surface sensor measurements. We assess the performance based on historical tests that are representative of the variation in possible pressure-volume behaviors and with typical noise levels on input sensor signals. The system output corresponds well with the original manual test interpretations, and provides in most cases reliable determination of leak-off and fracture pressures, fracture propagation and fracture closure pressures. Real-time test supervisory functionality in addition to standardization of test interpretation and data storage are immediate benefits of system implementation.

Abstract
Evaluation of cement placement is an important part of the majority of deepwater wells. Cement placement confirmation is an important step following a cementing operation. More than one technique can be used to provide information about the top of cement (TOC) and about the depth interval of a good bond between the formation and the casing. Determining the length of annular cement coverage, which is an indication of correct cement placement, is useful knowledge before drilling and/or completion operations can proceed. The requirement for additional and improved cement evaluation techniques is greater now than ever before.
A variety of methods can be used to evaluate cement placement. The routine approach after a casing or liner cement job uses a job chart to calculate lift pressure and actual vs. predicted system pressure. These data enable an estimate of cement height in the annulus to be made, but they do not confirm the TOC. These methods vary in accuracy and difficulty, depending on well conditions. Common TOC evaluation methods in specific wellbore casing/liner sections typically require running a temperature survey or cement bond log (CBL) sensors/systems on a wireline. These operations use the rig's critical path time for each wireline run, which can add risk or difficulties, depending on the well trajectory. In addition, cement bond evaluation for large diameter casing can be technically challenging because it can reach the upper threshold measurement limitations for conventional wireline-conveyed CBL tools.
Many operators now use logging-while-drilling (LWD) sonic sensors for compressional and shear data acquisition in openhole environments. Using the same sonic systems, with minimal additional rig time, logging data acquired through the casing/liner strings while running a drilling or clean out assembly can be evaluated to confirm the TOC.
This paper demonstrates how LWD sonic technology can provide confirmation of the TOC, saving a considerable amount of rig time, as compared to performing a dedicated wireline evaluation run or potentially unnecessary cement squeeze operations. The paper presents and discusses Gulf of Mexico (GOM) case studies. Based on various specific challenges, through correct data analysis, TOC evaluation best practices are implemented to optimize the LWD acoustic data acquisition inside the casing/liner. New data examination techniques are reviewed that can be applied to different scenarios, such as TOC evaluation behind dual pipes and real-time assessment for quick data analysis turn-around. In conjunction with the case studies, the paper also provides information about the LWD cased-hole logging techniques, analysis, and results of the data application.
