Thinking about stent thrombosis: How does angiographic flow relate to outcome?
Authors: Kern Morton J.
Published: December 2014

Key Points

Restoration of TIMI 3 flow after treating stent thrombosis reduces repeat stent thrombosis but not death or MI in the following year.

Understanding the mechanisms differentiating early, late and very late stent thrombosis will direct better initial treatment strategies.

Angiographic markers of coronary physiology (TIMI, TPG, Collateral grade) do not substitute for measured more quantitative indices of coronary blood flow.
High dose statins prior to PCI—change our modus operandis and start guideline therapy earlier?
Authors: Baquero Giselle A. , Gilchrist Ian C.
Published: December 2014

Key Points

The meta‐analysis examines the efficacy of high dose preloading of statin prior to PCI and demonstrate its association with lower PMI and cardiovascular events at short‐term.

Results from this analysis should encourage high‐dose pretreatment with statins prior to PCI, especially in patients with NSTE‐ACS.

A large randomize clinical trial would be desirable but not entirely necessary to initiate adoption of this novel strategy.
A radial resolution to a warfarin worry
Authors: Blankenship James C. , Berger Peter B.
Published: December 2014

Key Points

Time‐to‐hemostasis is not prolonged by un‐interrupted warfarin prior to diagnostic catheterization or coronary intervention using radial access, compared to no warfarin, with background anti‐platelet therapy of aspirin ± a thienopyridine.

This provides additional reassurance that a strategy of uninterrupted warfarin prior to coronary procedures using radial access is safe.

A strategy of interrupted warfarin prior to coronary procedures (with or without bridging therapy) has not been adequately tested.
Lipid‐laden plaques: Lesions “at‐risk” for distal embolization during PCI
Authors: Goldstein James A.
Published: December 2014

Key Points

The present study teaches that Lipidic Plaques pose greater risk for stenting induced distal embolization manifest as “No‐Reflow.”

The results may impact practice as they support the benefit of embolic protection devices to prevent stenting complications.

The present data emphasize the need for future prospective studies testing whether protective devices are most beneficial in lipid‐laden plaques.
Transcatheter device occlusion of the left ventricular outflow tract as treatment for severe aortic regurgitation in hypoplastic left heart syndrome
Authors: Elling R. , Stiller B. , Grohmann J.
Published: December 2014

Aortic regurgitation is a rare but dangerous condition in patients with hypoplastic left heart syndrome (HLHS). We report the case of a 2‐year‐old girl with HLHS with aortic/mitral stenosis (AS‐MS) subtype after stage II palliation via the bilateral bidirectional Glenn (BBDG) procedure, when aortic regurgitation presented with the clinical manifestation of a paroxysmal coronary steal phenomenon provoked by exertion. Transcatheter closure of the left ventricular outflow tract (LVOT) with an AmplatzerTM Vascular Plug 4 minimized and finally abolished aortic reflux without compromising either coronary perfusion or atrioventricular (AV) conduction. Midterm follow‐up over 3 years revealed complete disappearance of her symptoms, and follow‐up catheterization displayed complete LVOT closure. This case illustrates the promising potential of modern cardiac catherization techniques in certain cases and emphasizes that precise assessment of the native aorta and coronary system is critical in HLHS patients. © 2015 Wiley Periodicals, Inc.
Influence of hospital volume on outcomes of percutaneous atrial septal defect and patent foramen ovale closure: A 10‐years us perspective

Published: December 2014

Background: Contemporary data regarding percutaneous closure of atrial septal defect/patent foramen ovale (ASD/PFO) are lacking. We evaluated the current trends in utilization of ASD/PFO closure in adults and investigated the effect of annual hospital volume on in‐hospital outcomes. Methods: We queried the Nationwide Inpatient Sample between the years 2001 and 2010 using the International Classification of Diseases (ICD‐9‐CM) procedure code for percutaneous closure of ASD/PFO with device. Hierarchical mixed effects models were generated to identify the independent multivariate predictors of outcomes. Results: A total of 7,107 percutaneous ASD/PFO closure procedures (weighted n = 34,992) were available for analysis. A 4.7‐fold increase in the utilization of this procedure from 3/million in 2001 to 14/million adults in 2010 in US (P < 0.001) was noted. Overall, percutaneous ASD/PFO closure was associated with 0.5% mortality and 12% in‐hospital complications. The utilization of intracardiac echocardiography (ICE) increased 15 fold (P < 0.001) during the study period. The procedures performed at the high volume hospitals [2nd (14–37 procedures/year) and 3rd (>38 procedures/year) tertile] were associated with significant reduction in complications, length of stay and cost of hospitalization when compared to those performed at lowest volume centers (<13 procedures/year). Majority (70.5%) of the studied hospitals were found to be performing <10 procedures/year hence deviating from the ACC/AHA/SCAI clinical competency guidelines. Conclusions: Low hospital volume is associated with an increased composite (mortality and procedural complications) adverse outcome following ASD/PFO closure. In the interest of patient safety, implementation of the current guidelines for minimum required annual hospital volume to improve clinical outcomes is warranted. © 2014 Wiley Periodicals, Inc.

Published: December 2014

Lots of folks love New York, to borrow from the Empire State's long‐standing tourism slogan. But New York does not always reciprocate. That is certainly the case with the energy industry. A case in point is the interminable “moratorium” upon fracking, as imposed by the state's governor.1 Given his recent reelection, said executive policy is unlikely to change.

Published: December 2014

Background

Oral incontinence is a common complication after free flap reconstruction after ablation of oral cancers. The postoperative incontinence was corrected with strong suspension to the temporalis muscle in cases of major or total defect of lower lip muscles.

Methods

Eight patients with oral cancer with previous skin flaps for reconstruction of the lower lip had incontinence because of major or total loss of the lower lip muscle. A tendon graft was used as a suspension sling sutured to the anterior third of the bilateral temporalis muscle.

Results

Oral continence without drooling was achieved by suspension of the temporalis muscle with free movement of the lower lip.

Conclusion

This is a good option for correcting the incontinence after major or total loss of lower lip muscles in patients with oral cancer. © 2015 Wiley Periodicals, Inc. Head Neck 38: 683–688, 2016
Numerical Study of Heat Transfer and Separated Flow over Rectangular Obstacle in Jet
Authors: Malika Kabache , Amina Mataoui
Published: December 2014

This paper is about a separated reattaching flow over a hot rectangular obstacle. Two types of incoming flow are examined in order to show the influence of the external zone of the flow on the reattachment process. It comes about due to a wall jet and a boundary layer. The inner region of these two flows is similar, but their external regions are extremely different. The separating and reattaching flow phenomena are of particular interest in engineering fields such as for an aeronautical application. Wall jet flow over an obstacle occurs in many engineering applications such as environmental discharges, heat exchangers, fluid injection systems, cooling of combustion chamber wall in a gas turbine, automobile design, and others. In electronics cooling, the prediction of the Nusselt number distribution along the obstacles is necessary before the design of the apparatus. For a heated obstacle at a constant temperature,T= 350 K and an aspect ratio of 10 (L= 10H), the problem parameters are: (a) jet exit Reynolds number (Re) ranged from 1000 to 50000, (b) incoming flow configuration (boundary layer and wall jet). The ratio between the thickness of the nozzle (b) to the obstacle height (H) are examined simultaneously. The formulation is based on the SSTk–ωturbulence model. The results show that the increasing of nozzle thickness; enhances the heat transfer and considerably modifies the stagnation point location. The highest incoming flow momentum provides the greatest values of average Nusselt number. Such as the boundary layer case in comparison with the wall jet cases. The average Nusselt number is correlated according to problem parameters.
Psychophysiological Predictors of Working Alliance Among Treatment‐Seeking Women With Complex Trauma Exposure
Authors: Doukas Ashley , D'Andrea Wendy , Doran Jennifer , Pole Nnamdi
Published: December 2014

Research has established that trauma‐related symptoms may impede the formation of a strong working alliance (i.e., interpersonal connection, trust, and shared goals between therapist and client). As the alliance is critical in trauma‐focused therapy, we studied how clients’ pretherapy factors, including symptoms and psychophysiological arousal, predict treatment alliance. We examined symptoms and physiological responses in 27 women who had exposure to extreme interpersonal violence; all of whom were enrolled in therapy. All had symptoms consistent with a diagnosis of posttraumatic stress disorder. Clients completed measures of working alliance and were assessed before and after treatment on measures of symptoms and autonomic arousal. Autonomic assessment included measures of skin conductance and respiratory sinus arrhythmia (RSA), taken during baseline, while viewing positive and then trauma‐related slides, and during recovery. Higher alliance ratings were predicted by lower pretherapy skin conductance during trauma slides (r = −.41, p = .049) and recovery (r = −.44, p = .047) and higher RSA during baseline (r = .47, p = .027) and positive slides (r = .43, p = .044). Findings remained significant even after partialling pretherapy symptoms. These data on a high‐need but understudied population suggest that sympathetic and parasympathetic arousal may help traumatized clients effectively engage in therapy, further supporting the role of parasympathetic activity in social engagement.

Despite potential advantages in scalability and efficiency of web‐based training for trauma providers, few controlled trials of feasibility and effectiveness of web‐based mental health training have been performed. Our study compared web‐based training in 3 intervention skills (motivation enhancement [ME], goal setting [GS], behavioral task assignment [BTA]) with web‐based training plus telephone consultation, and a no‐training control. The primary outcome measures included objective measures of skills acquisition (standardized patient assessments). Results showed significant differences among the training conditions. The overall tests of differences among the groups were statistically significant for ME and BTA skills (p < .001 and p = .005, respectively), but not for GS (p = .245). The web training plus consultation group improved in ME skills by 0.35 units compared to 0.12 units in the web only group (p < .001) and no change in the control group (p = .001). For BTA skills, the web training plus consultation improved by 0.27 units compared to 0.17 units in the web only group (p = .175) and no change in the control group (p = .004). Overall, these findings support the use of web‐based dissemination for large‐scale training programs for trauma providers in health care delivery systems. Further studies are needed to clarify the specific role of consultation as an adjunct to web‐based training.
Thiadiazole derivatives as inhibitors for acidic media corrosion of artificially patinated bronze

Published: December 2014

Electrochemical impedance spectroscopy (EIS) and SEM‐EDX observations were used to evaluate the inhibiting effect of four thiadiazole derivatives, i.e. 2‐mercapto‐5‐amino‐1,3,4‐thiadiazole (MAT), 2‐mercapto‐5‐methyl‐1,3,4‐thiadiazole (MMeT), 2‐mercapto‐5‐acetylamino‐1,3,4‐thiadiazole (MAcAT) and 2‐mercapto‐5‐phenylamino‐1,3,4‐thiadiazole(MPhAT) on the corrosion of naked and artificially patinated bronze surface exposed to an acidic solution (pH 3) that simulates a strongly polluted rainfall. For comparison reasons, the inhibiting effect of benzotriazole (BTA) was also examined. In an attempt to better understand the influence of solution pH on the adsorption of the thiadiazole derivatives and to correlate their structural and electronic characteristics with the experimental inhibition efficiencies, quantum chemical calculations were performed starting with thiadiazole and its protonated derivatives. Finally, a possible inhibition mechanism of the thiadiazole protonated species on bronze corrosion was proposed. It was concluded that MMeT and MAT allow the stabilization of the patina layer, leading to the protection of the bronze substrate and their effectiveness significantly increase with the immersion time.

Performance enhancement of laser acquired from a newly developed double‐clad Yb3+/Tm3+ codoped fiber (YTDF) is demonstrated using dual‐pumping scheme. The laser uses a 2 m long YTDF fiber with a core dopant concentrations (in wt%) of 2.00 Yb2O3, 0.5 Tm2O3, 1.0 Al2O3, and 3.00 Y2O3 as a gain medium in conjunction with a pair of fiber Bragg grating in a linear cavity resonator to generate lasing at 1901.6 nm. The best efficiency of 2.9% and the highest output power of 27 mW are obtained by combining 927 nm pump with 905 nm pump. As compared to a single pumping scheme using 927 nm pumping source, about 0.43% increment in efficiency is observed with no evidence of rollover at the highest output power. The best combination is to use 200 mW of 800 nm pump with 927 nm pump, wherein only a total pump power of 1900 mW is required to generate 20 mW of 1.9 μm laser output. © 2015 Wiley Periodicals, Inc.

Published: December 2014

Three uniplanar shapes of electromagnetic band gap (EBG) structure as T‐shape, fractal shape, and interdigital capacitors are investigated for antenna applications. The proposed EBG shapes are etched on the ground plane of the planar inverted‐F antenna (PIFA) to improve the impedance bandwidth, reduce the antenna size, increase the gain, and improve radiation pattern. Next, two trapezoidal shaped slots are etched on the radiating plate of PIFA antenna to excite two resonant frequencies. The proposed antenna is designed to cover two narrow bands at GSM 1.8 GHz, upper WLAN 5.2 GHz and a wideband from 2.4 to 4 GHz. Effect of the laptop is investigated on the performance of the proposed antenna. Finally, the effect of these new EBG shapes on mutual coupling reduction between two pair of antennas is studied for multiple input multiple output application in laptop device. © 2015 Wiley Periodicals, Inc.

Published: December 2014

In this article, a novel coplanar waveguide (CPW)‐fed triple‐band antenna for WLAN/WiMAX is proposed. The proposed antenna is simply composed of three arc‐shaped strips and is capable of generating three separate resonant modes with good impedance matching conditions. The effects of varying the dimension on the proposed antenna performance were also studied. Prototypes of the proposed antenna were constructed and experimentally studied. The experiment results show that the proposed antenna covers 1.66–2.71, 2.95–4.54, and 5.02–6.10 GHz with −10 dB return loss, covering all the 2.4/5.5/5.8 WLAN bands and 2.5/3.5/5.5 GHz bands. Furthermore, this CPW‐fed monopole antenna exhibits a nearly omnidirectional radiation pattern in the H‐plane and a dipole‐like radiation pattern in the E‐plane. Also, good antenna gains for operating bands were obtained. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:268–273, 2015

A simple approach to achieve polarization diversity in broadband reflectarrays using single‐layered rectangular patch elements
Authors: Guo Lu , Tan Peng‐Khiang , Chio Tan‐Huat
Published: December 2014

This article presents a simple method to realize polarization diversity in broadband reflectarrays. The wideband characteristic of the reflectarray is achieved using rectangular patch elements arranged in a subwavelength grid on a single layer of substrate; while the polarization diversity of the reflectarray is obtained by simply rotating the feed horn antenna. As the two orthogonal x‐ and y‐component of the rectangular patch element demonstrate relatively negligible interaction, the circular polarized (CP) reflectarrays with linearly polarized feed that have been proposed previously are found to be capable of supporting quadruple polarizations by means of rotating the feed. Based on the rectangular patch elements, an offset‐fed 405 × 405 mm2 reflectarray with 0.3λ grid and centered at 10 GHz is designed and developed for right‐hand circular polarization (RHCP). In an effort to realize the polarization diversity, the feed horn antenna is subsequently rotated relative to the array with angles of 0°, 90°, and 135° for vertical polarization, horizontal polarization, and left‐hand circular polarization (LHCP), respectively. The viability and effectiveness of the proposed simple method for polarization diversity is experimentally verified. The measured results show that the 1‐dB gain bandwidth for all four polarizations can reach as large as 18%. Furthermore, the 3‐dB axial ratio bandwidths for CP operations are remarkably wide, above 36% and 40% for RHCP and LHCP, respectively. © 2015 Wiley Periodicals, Inc.
