Published: November 2018

Background and Aim:
To analyse short-term results after the Bentall operation and get clinical considerations.

Methods:
One hundred and twenty-two patients (mean age 60.4 ± 15.8 years, 99 males,23 females) underwent Bentall operation from January 2015 to December 2017 for treatment of ascending aorta expansive aneurysm (i.e. degenerative aneurysm with tricuspid aortic valve, n = 69; bicuspid valve, n = 37; Marfan syndrome and other genetical disorders, n = 13; redo procedures n = 3). Associate procedures (i.e. coronary artery bypass grafting, mitral valve replacement, other) were performed in 26 patients (21.3%). Euroscore II was 4.7% ± 3.9%. Mean follow-up (99.2% complete) was 20 ± 10 months.

Results:
In-hospital mortality was 1.6% (1% for isolated Bentall). Three-year survival, freedom from cardiac death, from endocarditis, frome reoperation were 97 ± 1.2%, 99 ± 1.3%, 93 ± 5.1%, 98 ± 1.8%, respectively. No thromboembolism and major bleeding complications were observed. Independent predictors of all-cause death were preoperative higher left ventricular (LV) end-diastolic diameter (71.6 ± 12 vs 53.6 ± 8.6 mm; P = 0.009), LV end-systolic diameter (47.7 ± 9.2 vs 36.8 ± 7.9 mm; P = 0.02), lower LV ejection fraction (43.3 ± 15 vs 56.2 ± 8.7%; P = 0.015). Survival was 98.4 ± 1.6% after isolated Bentall, and 92 ± 5.4% after associated procdures (P = 0.04). As compared to preoperative values, clnical and echocardiography follow-up showed improvement of LV function and NYHA class.

Conclusions:
Excellent results can be expected after Bentall operation. Low rate of operative mortality and late complications, and significant improvement of clinical status make this operation the gold standard and the reference surgery therapy for the treatment of ascending aorta aneurysms. In presence of dilatation and dysfunction of the left ventricle, adequate medical treatment is necessary to improve survival.
RF02 ANOMALOUS AORTIC CORONARY ARTERY ORIGIN: A PARAMETRIC STRUCTURAL FINITE ELEMENT ANALYSIS AND COMPUTATIONAL SIMULATION.
Authors: Rito M. Lo , Formato G.M. , Auricchio F. , Frigiola A. , Giamberti A. , Conti M. 
Published: November 2018

Background and aim:
In anomalous aortic origin of coronary arteries (AAOCA) underlying ischemic mechanism during high stress conditions have still to be elucidated. The study aims to understand the biomechanics of such a condition and in particular how the lumen of the AAOCA may narrow during aortic expansion.

Methods:
We create a parametric computer-aided designed (CAD) model of the aortic root and AAOCA origin and perform a static finite element analysis (FEA) on 10 models with different angles of take-off and intramural penetration at three different loading conditions (i.e. stress condition). The model is defined by twenty-three parameters describing aortic root geometry and allows to vary coronary position, take-off angle, degree of intramural penetration, and length of the intramural course to simulate the pathological conditions of AAOCA.

Results:
We show that the AAOCAs experience a reduced luminal expansion (LE) (LE = 1.85%, 5.98%, 10.42%) compared to the healthy ones (LE = 11.9%, 22.43%, 36.66%,) at 120-150-180 mmHg of aortic root pressure respectively. Acute angles of take-off lead to elongated ostia, with an eccentricity (e) that increases with aortic expansion (i.e. e = 0.72-0.69-0.66 at 120-150-180 mmHg, take-off angle = 35’ and 50% penetration).

Conclusions:
The study describes for the first time an idealized geometrical model as a proof of concept for static structural finite element simulations to assess the role of specific geometrical features on AAOCA physiopathology. The possible mechanism of lumen reduction in AAOCA can rely on biomechanical reasons and computational simulations may allow patient specific predictive model in future.

Authors: Weltert L. , Turani F. , Falco M. , Candidi F. , Barchetta R. , D’Aleo S. , De Paulis R. 
Published: November 2018

Background and aim:
Objective Renal Replacement Therapy (RRT) with oXiris filter is used in sepsis with Acute Kidney Injury (AKI) but few clinical studies compare the adsorbing effect of oXiris filter on the inflammatory mediators to traditional RRT.
The aim of this study is to Confirm whether oXiris decreases cytokines and procalcitonin in sepsis septic shock
Test if this effect is superior to RRT and if this translates into a better cardio renal response.

Methods: :
A Cohort of 73 patients admitted to three Intensive Care Units with a diagnosis of sepsis.
InterLeukin-6, Procalcitonin, Cardiorenal indices and SOFA-score were compared before (T0) and at the end of the treatments (T1).
Propensity Matching was performed including all pre-treatment variables, final cohorts resulted identical in all aspects. Of 50 patients submitted to oXiris filter 32 could be matched to 22 septic patients who received traditional RRT

Results: :
IL6 and Procalcitonin decreased significantly more in the oXiris group (p < 0,01)
MAP increased (p < 0,01) and noradrenaline dosage decreased in oXiris group (p < 0,01)
PaO2/FIO2 ratio, diuresis, SOFA improved in the oXiris group (p < 0,05)

Conclusions: :
In septic shock patients with Acute Kidney Injury, IL6 and procalcitonin decrease significantly more in the oXirs group then in the RRT group.
This is significantly associated with an improvement of the cardio-renal function and the clinical condition.
The study confirms that RRT with oXiris filter may be useful in sepsis where other convective diffusive techinques fail.

Published: November 2018

Background:
Since 1968 Bentall and DeBono first described the technique for aortic root replacement with the reimplantation of the coronary arteries. This operation has been considered the gold standard in the surgical treatment of the ascending aorta and aortic valve disease. At the end of the 1990 s the Shelhigh No-React biological valved conduit was introduced in Europe for Bentall operation. The aim this study was to report the short and long term follow-up with the Shelhigh conduit.

Methods:
From 2001 to 2010, 45 patients (mean age 69.6 ± 6.9 years) underwent aortic root replacement with Shelhigh conduit. Endocarditis (2.2%), type A aortic dissection (20%), aneurysm (77.8%) were the most important indications for surgery. End-points were: survival at 1, 5 and 10years, conduit-related major complications and death, freedom from aortic root structural deterioration and reoperation.

Results:
The median follow-up was 8.9 years (0 to 14.6). The overall hospital mortality rate was 4 patients (8.9 %). The overall estimated survival rates at 1, 5 and 10 years were 86.4 ± 5.2, 81.8 ± 5.8 and 65.9 ± 7.6 respectively. Redo surgery was necessary in 5 cases (11.1 %); in 3 of them (6.7%) there was evidence of false aneurysm. The overall estimated freedom from reoperation at 1, 5 and 10 years was 95.1 ± 3.4, 92.6 ± 4.1 and 92.6 ± 4.1 respectively.

Conclusions:
In our experience the Shelhigh-NoReact biological valved conduit showed acceptable results. According to the literature, the high rate of aortic root related reoperation (6.7%) and early mortality (8.9%) may be explained by the clinical and demographic features of the studied group.

Blockchains, Formulary Evaluations and Health Technology Assessment
Authors: Langley Paul , Martin Robert E 
Published: November 2018

Blockchains have the potential, if appropriately implemented and managed, of contributing to a fundamental change in the application of techniques of health technology assessment in formulary decision making. Rather than continuing to rely on claims made by manufacturers that are non-evaluable, the introduction of blockchains as adjunct to the electronic medical record, meet an unmet medical need in enabling a platform for the real time assessment of claims. Rather than focusing the case for their product on lifetime cost-per-QALY models, which have no chance of ever being validated, the blockchain platform offers a low cost opportunity for claims evaluation. Manufacturers would be required to abandon the construction of imaginary cost-per-QALY worlds to support claims for pricing and formulary trier position, in favor of claims that can be evaluated and reported back to formulary committees in a short yet meaningful time horizon. Manufacturers would present a claims assessment protocol as part of the formulary submission package. If agreed with the formulary committee, the protocol would be implemented and managed through the patient blockchain membership. Claims would be monitored and evaluated in real time with a final report to the formulary committee in a matter of months. Lifetime imaginary claims for cost-per-QALY, set alongside willingness-to-pay thresholds, would be a thing of the past. Pricing decisions and formulary placement would reflect a robust evidence base and not just extrapolations from pivotal clinical trials.

LEARNER AUTONOMY IN EFL/ESL CLASSROOMS IN BANGLADESH: TEACHERSâ€™ PERCEPTIONS AND PRACTICES
Authors: Begum Jahanara 
Published: November 2018

Abstract:
In recent years, there has been a growing recognition of language teaching being more and more communication oriented. The traditional classroom teaching is facing a big challenge and is gradually being replaced by learner-centered approaches putting learner as individual into the core of learning process. This means learner autonomy gets to be enhanced to meet the need of the new teaching mode. While a great deal of researches have been done on the concept and development of learner autonomy , limited studies have investigated the ways and means of classroom practices of teachers in fostering learner autonomy in tertiary level EFL/ESL classrooms in Bangladesh. This paper examines what teachers think about learner autonomy as well as the strategies they use to develop learners autonomy in a university setting using a qualitative approach. The findings revealed that although university teachers are acquainted with what learner autonomy means, there are some challenges of developing learner autonomy in the classroom due to a number of lacking, such as teacherâ€™s preparation, studentsâ€™ reluctant attitude, suitability for different disciplined students and class timing.

Abstract
Observations of dust-enshrouded evolved stars selected from infrared catalogs requiring high positional accuracy, like infrared spectroscopy or long baseline radio interferometric observations, often require preparational observational steps determining a position with an accuracy much better than 1″. Using phase-referencing observations with the Very Large Array at its highest resolution, we have compared the positions of SiO 43 GHz masers in evolved stars, assumed to originate in their infrared detected circumstellar shells, with the positions listed in the MSX, WISE, 2MASS, and Gaia catalogs. Starting from an MSX position it is, in general, simple to match 2MASS and WISE counterparts. However, in order to obtain a Gaia match to the MSX source it is required to use a two-step approach due to the large number of nearby candidates and low initial positional accuracy of the MSX data. We show that the closest comparable position to the SiO maser in our limited sample never is the MSX position. When a plausible source with a characteristic signature of an evolved star with a circumstellar shell can be found in the area, the best indicator of the maser position is provided by the Gaia position, with the 2MASS position being second best. Typical positional offsets from all catalogs to the SiO masers are reported.
New Hot Subdwarf Stars Identified in Gaia DR2 with LAMOST DR5 Spectra
Authors: Lei Zhenxin , Zhao Jingkun , Németh Péter , Zhao Gang 
Published: November 2018

Abstract
We selected 4593 hot subdwarf candidates from the Gaia DR2 Hertzsprung–Russell (HR) diagram. By combining the sample with Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) DR5, we identified 294 hot subdwarf stars, including 169 sdB, 63 sdOB, 31 He-sdOB, 22 sdO, 7 He-sdO, and 2 He-sdB stars. The atmospheric parameters (e.g., T
eff, log g, log(nHe/nH)) are obtained by fitting the hydrogen (H) and helium (He) line profiles with synthetic spectra. Two distinct He sequences of hot subdwarf stars are clearly presented in the T
eff–log g diagram. We found that the He-rich sequence consists of the bulk of sdB and sdOB stars, as well as all of the He-sdB, He-sdO, and He-sdOB stars in our samples, while all the stars in the He-weak sequence belong to the sdO spectral type, combined with a few sdB and sdOB stars. We demonstrated that the combination of Gaia DR2 and LAMOST DR5 allows one to uncover a huge number of new hot subdwarf stars in our Galaxy.
Accretion in a Dynamical Spacetime and the Spinning Up of the Black Hole in the Gamma-Ray Burst Central Engine
Authors: Janiuk Agnieszka , Sukova Petra , Palit Ishika 
Published: November 2018

Abstract
We compute the evolution of a quasi-spherical, slowly rotating accretion flow around a black hole, whose mass and spin evolve adequately to transfer of mass and energy through the horizon. Our model is relevant for a central engine driving a long gamma-ray burst (GRB) that originates from the collapse of a massive star. The computations of a GRB engine in a dynamically evolving spacetime metric are important specifically due to the transient nature of the event, in which a huge amount of mass is accreted and changes the fundamental black hole parameters—its mass and spin—during the process. We discuss the results in the context of the angular momentum magnitude of the collapsing star. We also study the possible formation and evolution of shocks in the envelope, which may temporarily affect accretion. Our results are important for the limitations on the mass and spin range of black holes detected independently by electromagnetic observations of GRBs and gravitational waves. We speculate on the possible constraints for the final masses and spins of these astrophysical black holes. It is shown that the most massive black holes are not formed in a powerful GRB explosion if the cores of their progenitors were only weakly rotating.
Double Nuclei in NGC 908 and NGC 1187
Authors: Menezes R. B. , Steiner J. E. 
Published: November 2018

Abstract
We analyze optical data cubes of the nuclear regions of two late-type galaxies, NGC 908 and NGC 1187, obtained with the Integral Field Unit of the Gemini Multi-Object Spectrograph. Both data cubes show stellar structures consistent with double nuclei. The morphology of the line-emitting areas in the central region of NGC 1187 is also of a double nucleus, while the spatial morphology of the line-emitting areas in the data cube of NGC 908 is consistent with a circumnuclear asymmetric ring. The emission-line ratios of the nuclear spectra (and, actually, along the entire field of view) of both galaxies are characteristic of H ii regions. In particular, based on its emission-line properties, the circumnuclear ring in NGC 908 can be identified as a star-forming ring. The observed spatial morphology of the stellar emission and also the differences in the properties of the stellar populations detected in the stellar nuclei of NGC 908 suggest that the most likely scenario to explain the double stellar nucleus in this object involves a minor merger, probably with a high mass ratio. On the other hand, considering the similar properties of the stellar populations in the stellar nuclei of NGC 1187, together with the stellar and gas kinematic properties, we conclude that the most likely scenario to explain the double stellar and gas nucleus in this galaxy involves the stellar and gas kinematics, in the form of a circular nuclear disk subject to perturbations.
