Актуальність. Цукровий діабет 2-го типу (ЦД2) є чинником ризику артеріосклерозу нижніх кінцівок, а зв’язок зі станом венозного басейну судин ніг залишається вивченим недостатньо, не з’ясовано ефективність хірургічних методів лікування хворих із варикозом. Мета дослідження: проаналізувати характер перебігу варикозної хвороби вен ніг та ефективність лікувальних заходів на тлі ЦД2. Матеріали і методи. Під наглядом перебувало 302 хворі (75 чоловіків і 227 жінок віком 29–72 роки), 16 % з яких раніше перенесли флеботромбоз, а частота II–VI класів венозної недостатності становила відповідно 10, 14, 37, 16 і 23 %. Ендовенозну лазерну коагуляцію виконано 263 пацієнтам, а 39 — традиційну флебектомію або лігування перфорантів. Результати. Серед обстежених хворих на варикозну хворобу вен нижніх кінцівок ЦД2 виявлено в 9 % випадків, частіше у чоловіків і пацієнтів старших вікових груп на тлі атеросклерозу судин ніг (здухвинних, стегнових, гомілкових, підколінних артерій), що супроводжувалося частішим залученням до процесу великої підшкірної вени та приустєвим її розширенням, переважанням тяжких класів венозної недостатності, значно гіршими результатами хірургічного лікування варикозу та більшою частотою розвитку ускладнень, незважаючи на частіше фонове використання рівароксабану і низькомолекулярних гепаринів, а ефективність ендовенозної лазерної абляції за чотири тижні після її проведення поступається показнику в групі без ЦД2, при цьому рівень глікемії обернено корелює з показником поверхневого натягу венозної крові, що має прогностичну значущість у контексті подальших лікувальних заходів. Висновок. Наявність ЦД2 є чинником ризику тяжкого перебігу варикозу вен ніг, негативним фактором щодо прогнозу ефективності хірургічного лікування цього захворювання й числа ускладнень.
Changes in the Profile of Endovascular Procedures Performed in Freestanding Dialysis Access Centers over 15 Years
Authors: Beathard Gerald A. , Urbanes Aris , Litchfield Terry 
Published: April 2017

Background and objectives
Marked changes occurred in the vascular access profile of patients receiving hemodialysis in the United States over the 15-year period of 2001–2015. This study was undertaken to evaluate how these changes have affected dialysis access maintenance and salvage procedures performed in freestanding dialysis access centers and to examine the effectiveness, efficiency, and safety of these procedures in this setting.

Design, setting, participants, & measurements
Data were collected from freestanding, dedicated dialysis access centers operating under a common system of management. Data were available on 689,676 dialysis access procedures. Data relating to case mix, procedure outcome, procedural time, and intraprocedural and immediate postprocedural complications were analyzed.

Results
The arteriovenous procedure profile changed from one characterized by approximately equal numbers of angioplasties and thrombectomies performed on arteriovenous grafts (AVGs) to one characterized primarily by angioplasties performed on arteriovenous fistulas. The percentage of angioplasties performed throughout the study was significantly greater than thrombectomies, with a mean of 67.9% versus 32.1% (P<0.001). Interventional procedures did not decrease with increasing arteriovenous fistula utilization in prevalent patients receiving dialysis. The incidence roughly paralleled the increasing prevalence of this type of access. A decreasing percentage of AVG utilization resulted in a progressive, roughly parallel, but disproportionately higher, decrease in the percentage of AVG procedures (P<0.001). A progressive improvement in procedure outcomes and a decrease in complication rates and procedure times were observed (P<0.001 for each). A progressive decrease in tunneled dialysis catheter placement was also observed.

Conclusions
The procedure profile treated in freestanding, dedicated dialysis access centers changed significantly over 15 years, reflecting the changes that have occurred in the vascular access profile of the dialysis population.

El documento presenta los resultados de una investigación orientada a identificar las competencias claves que debe poseer el docente del futuro según la opinión de 911 estudiantes de carreras de Educación de la Universidad Estatal a Distancia de Costa Rica. La metodología consistió en la aplicación de una encuesta mediante la cual se les solicitó a los participantes indicar las cuatro competencias más importantes, que según ellos, debería poseer el docente para desempeñarse adecuadamente dentro de los siguientes 20 años. Las competencias mencionadas por los participantes fueron ordenadas según el sistema de clasificación de Villa y Poblete (2008) en el que se identifican 35 competencias genéricas, de ellas los participantes hicieron mención a 15 competencias y las cuatro más mencionadas fueron el uso de las tecnologías, el sentido ético, la orientación al aprendizaje y las relaciones interpersonal. Pese a la relevancia que parece tener las competencias mencionadas; los participantes dejan de lado competencias basales como las cognitivas y las lingüísticas.
The Effects of Time Pressure on Belief Revision in Accounting: A Review of Relevant Literature within a Pressure-Arousal-Effort-Performance Framework
Authors: Pietsch Christian P. R. , Messier William F. 
Published: April 2017

ABSTRACT
This study advances several propositions about the effects of time pressure on individuals' belief revisions within a pressure-arousal-effort-performance framework. There is a significant body of research that documents the importance of both time pressure and order effects in an accounting environment. However, prior research has not investigated how the order of information affects individuals' belief revision processes under varying levels of time pressure, even though the inclusion of a time pressure variable has been noted as relevant in belief revision research, both in general (Hogarth and Einhorn 1992) and in accounting (Kahle, Pinsker, and Pennington 2005; Trotman and Wright 2000). In this review, we extend prior belief revision research in accounting by describing how time pressure interacts with personal and task variables and the subprocesses described in the belief-adjustment model (Hogarth and Einhorn 1992). Propositions are advanced on the effects of time pressure on individuals' belief revisions. A better understanding of such interactive effects helps to explain the mixed results identified in prior studies.

Primary care knowledge and beliefs about physical activity and health: a survey of primary healthcare team members
Authors: Wheeler Patrick C , Mitchell Ralph , Ghaly Melvinder , Buxton Kim 
Published: April 2017

BackgroundPhysical activity has numerous health benefits and the primary healthcare team are ideally suited to promote activity. The Royal College of General Practitioners (RCGP) has announced physical activity to be a clinical priority in the next few years. However little attention is given to this in medical training, with unclear levels of knowledge and confidence.AimTo explore the primary healthcare team knowledge of the benefits of physical activity in preventing and treating ill health.Design & settingQuestionnaire-based study, from six East Midlands sites in the UK.MethodSelf-completed anonymised questionnaire.ResultsThree hundred and two results were obtained in total, from 166 GPs, 65 GP registrars, and 71 practice nurses. There was a mean age of 44.8 years (range 22–71), with 62% female responders. Fifty-five per cent of responders underestimated UK recommended activity guidance. Responders considered activity promotion as part of their professional role, but this was discussed about one-third as often as other health promotion behaviours, such as weight or smoking. Barriers reported were lack of time (91.2%) and resources (36.8%).ConclusionThis study has shown reasonable knowledge of recommended levels of activity and accrued health, but most underestimated UK guidance, suggest inadequate levels of activity for optimal health may be being recommended. Confidence in this area is lower in GP registrars than GPs which may mirror other health problems. There was a poor recognition of simple tools to assess the level of physical activity, and low levels of onward signposting or recommendations. If physical activity is to be a clinical priority area of the RCGP, then further opportunities for professional development may be required.

OBJECTIVE: To evaluate levels of anxiety-trait and state presented by nurses from a hospital environment during the work process.
METHOD: This is a descriptive cross-sectional study with a quantitative approach, performed with a sample of 30 nurses. Data collection was done through the Trait-State Anxiety Inventory (IDATE-T and IDATE-E) and an identification questionnaire prepared by the researcher. The software GraphPad Prism was used for the statistical analysis of the results.
RESULTS: The results showed that, 12 nurses presented scores corresponding to high levels of anxiety-trait. It was also observed that the highest levels of anxiety are present in the female gender, in the age group of 31-40 years, in individuals that are single, who have more than one employment, with less than 10 years of professional activity and who do not practice physical activities.
CONCLUSION: It was observed a high level of anxiety-state in a third of the respondents, and it becomes essential for the organizational field to detect sectors that trigger stress and anxiety due to the type of clientele.
Double Stars and Astrometric Uncertainties in Gaia DR1
Authors: Makarov Valeri V. , Fabricius Claus , Frouard Julien 
Published: April 2017

Abstract
A significant number of double stars with separations up to 2.5 arcsec are present in the Gaia Data Release 1 astrometric catalogs. Limiting our analysis to a well-studied sample of 1124 doubles resolved by Hipparcos, provided with individual Tycho component photometry and cross-matched with the TGAS catalog, we estimate a rate of at least 3% for brighter double stars in Gaia DR1, which should be resolved in future data releases. Gaia astrometric results are affected by unresolved duplicity. The variance-normalized quadratic differences of proper motion between Gaia and Hipparcos do not follow the expected

distribution and show signs of powerful degradation in the components aligned with the axes of the double systems. This concerns only pairs with separation below 1.2–1.5 arcsec, which mostly remain unresolved in Gaia DR1. On the other hand, the orthogonal proper motion components and parallaxes do not have any detectable perturbation, as well as all astrometry for separations above 1.5 arcsec. Gaia parallaxes do not seem to be perturbed by duplicity, with Gaia–Hipparcos differences being systematically smaller than the expectation. The rate of incorrectly identified, or swapped, companions is estimated at 0.4%.
Large Host-galaxy Dispersion Measure of Fast Radio Bursts
Authors: Yang Yuan-Pei , Luo Rui , Li Zhuo , Zhang Bing 
Published: April 2017

Abstract
Fast radio bursts (FRBs) have excessive dispersion measures (DMs) and an all-sky distribution, which point toward an extragalactic or even a cosmological origin. We develop a method to extract the mean host galaxy DM (

) and the characterized luminosity (L) of FRBs using the observed DM–flux data, based on the assumption of a narrow luminosity distribution. Applying Bayesian inference to the data of 21 FRBs, we derive a relatively large mean host DM, i.e.,

with a large dispersion. A relatively large DMHG of FRBs is also supported by the millisecond scattering times of some FRBs and the relatively small redshift z = 0.19273 of FRB 121102 (which gives

). The large host galaxy DM may be contributed by the interstellar medium (ISM) or a near-source plasma in the host galaxy. If it is contributed by the ISM, the type of the FRB host galaxies would not be Milky Way–like, consistent with the detected host of FRB 121102. We also discuss the possibility of having a near-source supernova remnant, pulsar wind nebula, or H ii region that gives a significant contribution to the observed DMHG.

Authors: Attia Khalid A M , El-Abasawi Nasr M , El-Olemy Ahmed , Abdelazim Ahmed H 
Published: April 2017

Abstract
HPLC method was developed for the selective determination of phenazopyridine hydrochloride (PAP) in the presence of its computationally selected metabolite. Density functional theory was applied as a computational model to study the energy of PAP metabolites, and the results revealed that 2,3,6-triaminopyridine (TAP) is the most stable metabolite. Good resolution and separation of PAP from TAP was achieved using a reversed-phase BDS Hypersil C18 column with a mobile phase consisting of acetonitrile–water (75 + 25, v/v) at flow rate of 1 mL/min and with UV detection at 280 nm. The linear regression analysis data for the calibration plot of PAP showed a good linear relationship over the concentrationrange of 5–45 μg/mL, with an LOD of 0.773 μg/mL. Moreover, a theoretical investigation of the relationship between the stationary phaseand the studied molecules was performed to confirm the experimental results. The proposed method was successfully applied for the selective determination ofPAP in pharmaceutical formulation. In addition, the obtained results were statistically compared to a reported method, with no significant differences foundbetween the investigated method and the reported onewith respect to accuracy and precision.
Results of a 10‐year survey of workload for 10 treatment vaults at a high‐throughput comprehensive cancer center

Published: April 2017

AbstractThe workload for shielding purposes of modern linear accelerators (linacs) consists of primary and scatter radiation which depends on the dose delivered to isocenter (cGy) and leakage radiation which depends on the monitor units (MUs). In this study, we report on the workload for 10 treatment vaults in terms of dose to isocenter (cGy), monitor units delivered (MUs), number of treatment sessions (Txs), as well as, use factors (U) and modulation factors (CI) for different treatment techniques. The survey was performed for the years between 2006 and 2015 and included 16 treatment machines which represent different generations of Varian linear accelerators (6EX, 600C, 2100C, 2100EX, and TrueBeam) operating at different electron and x‐ray energies (6, 9, 12, 16 and 20 MeV electrons and, 6 and 15 MV x‐rays). An institutional review board (IRB) approval was acquired to perform this study. Data regarding patient workload, dose to isocenter, number of monitor units delivered, beam energies, gantry angles, and treatment techniques were exported from an ARIA treatment management system (Varian Medical Systems, Palo Alto, Ca.) into Excel spreadsheets and data analysis was performed in Matlab. The average (± std‐dev) number of treatment sessions, dose to isocenter, and number of monitor units delivered per week per machine in 2006 was 119 ± 39 Txs, (300 ± 116) × 102 cGys, and (78 ± 28) × 103 MUs respectively. In contrast, the workload in 2015 was 112 ± 40 Txs, (337 ± 124) × 102 cGys, and (111 ± 46) × 103 MUs. 60% of the workload (cGy) was delivered using 6 MV and 30% using 15 MV while the remaining 10% was delivered using electron beams. The modulation factors (MU/cGy) for IMRT and VMAT were 5.0 (± 3.4) and 4.6 (± 1.6) respectively. Use factors using 90° gantry angle intervals were equally distributed (~0.25) but varied considerably among different treatment techniques. The workload, in terms of dose to isocenter (cGy) and subsequently monitor units (MUs), has been steadily increasing over the past decade. This increase can be attributed to increased use of high dose hypo‐fractionated regimens (SBRT, SRS) and the increase in use of IMRT and VMAT, which require higher MUs per cGy as compared to more conventional treatment (3DCRT). Meanwhile, the patient workload in terms of treatment sessions per week remained relatively constant. The findings of this report show that variables used for shielding purposes still fall within the recommendation of NCRP Report 151.
