Authors: Zhang Long , Zhao Wei , Xu Qinfu , Zhao Yumiao , Zhao Junjie , Ren Yin-long , Liu Yu-jing , Li Jing , Xu Ai-Guo 
Published: March 2016

<p class="Abstract">To improve efficacy of non-invasive positive pressure ventilation (NPPV), this study investigated the combination of NPPV with naloxone in COPD patients with respiratory failure. One hundred four patients with COPD-related respiratory failure were enrolled prospectively and randomly divided into a control group treated with NPPV alone (n = 52) and an observation group treated with NPPV combined with 4.0 mg naloxone by continuous infusion (n = 52). At 3 and 5 days after the start of treatment, the respiratory mechanics, pulmonary function, and oxygen metabolism parameters were significantly improved in the NPPV + naloxone group compared to the NPPV alone group (p&lt;0.05). Further, the improvements in the NPPV plus naloxone group were greater at day 5 than at day 3 (p&lt;0.05). These findings indicate that non-invasive positive pressure ventilation combined with naloxone can more effectively improve respiratory mechanics, pulmonary function and oxygen metabolism of COPD patients with respiratory failure than NPPV alone, offering a new treatment approach.</p><p> </p>
Problem-based learning on cell biology and ecophysiology using integrated laboratory and computational activities
Authors: Sousa C. 
Published: March 2016

<p><span>Since all the known biological systems require water for their basic biochemical processes, one can find several osmoregulation mechanisms on living organisms for adaptation to related environmental challenges. Osmosis is a cellular mechanism of water movement across membranes which is known to be present throughout the tree of life and occurs by either diffusion across the membrane bilayer or by a faster movement mediated by transmembrane channel proteins, called aquaporins. The expression of aquaporins is regulated at, the cellular level, by environment conditions such as hydric stress, therefore allowing the adaptation of organisms to increase salinity in soils, water deprivation and increase beverage intake. </span></p><p><span>Osmosis and diffusion concepts have been described to be difficult to learn, so, in order to promote meaningfull learning, we used a problem-based learning approach that integrates a laboratory activity and a computer simulation model of osmosis and a two phase conceptual mapping.</span></p><p><span>We observed that high school students developed adequate laboratory skills and were able to communicate their results as text and using scientific drawings; and the learning environment was adequate. Therefore we presented a successful implementation case of integrated PBL, in a public portuguese school, that may constitute an example to facilitate the implementation of active inquiry strategies by other teachers, as well as the basis for future research.</span></p>
When in doubt, aspirate
Authors: Blankenship James C. 
Published: March 2016

Key Points

Coronary embolization accounts for about 2% of ST elevation myocardial infarctions (STEMI).
Thrombus aspiration may be particularly effective in these cases and may prevent the need for coronary stenting.
Despite recent guidelines assigning a class III recommendation to routine thrombus aspiration, selective thrombus aspiration based on angiographic appearance may be effective.
Duration of dual anti‐platelet therapy following drug eluting stents
Authors: Bang Vigyan V. , Levy Michael S. 
Published: March 2016

Key Points

This meta‐analysis suggests that abbreviated DAPT (<6 months) could be considered in patients undergoing PCI with current generation drug eluting stents (DES).
Extended DAPT strategy (>1 year) may be appropriate in those patients in whom prevention of stent and non‐stent‐related coronary events are likely to offset the bleeding complications.
Additional randomized trials are needed to evaluate the optimum duration of DAPT in patients with the latest generation DES and current antiplatelet drugs.
Back to nature: A more natural alternative to the PTFE covered stent: Twenty‐two years in the making
Authors: Heuser Richard R. 
Published: March 2016

Key Points

The introduction of easily deployed covered stents has made PCI safer.
The homemade venous and PTFE covered stent were effective but not practical for sealing perforations.
The novel pericardial covered stent graft goes back to a more natural covering and is more easily deployed.
Iatrogenic atrial septal defect after implantation of MitraClip device: treatment to whom and when?
Authors: Lakkas L. S. 
Published: March 2016

AbstractSuccessful MitraClip implantation, although deteriorates mitral regurgitation, leads inevitably to the presence of an iatrogenic atrial septal defect, because of the large guiding catheter used. Half of them will close immediately after implantation of the device, in the next 6 months, but the remaining may persist. Although the primary effect of their existence, is associated with a relatively small left to right shunt, relieving left atrium from chronic elevated pressure, there is not enough data in the literature concerning progression in time, leading to the question, whether they should be closed or not. This is a case report of a patient with severe ischemic mitral regurgitation, treated by implantation of two MitraClip devices, with concomitant iatrogenic atrial septal defect and left to right shunt.
Cardiac CT for the Interventional Cardiologist
Authors: Jones D. A. , Cospite V. , Pugliese F. 
Published: March 2016

AbstractCardiac computed tomography (CT) is a rapidly evolving imaging modality that has developed quickly over the last decade, to establish itself as a robust non‐invasive method to assess coronary artery disease. Qualitative and quantitative assessment of atherosclerotic coronary stenosis with cardiac CT has been favorably compared with invasive coronary angiography and intravascular ultrasound (IVUS) and importantly may help improve risk stratification and predict prognosis. Cardiac CT can visualize coronary artery bypass grafts with high diagnostic accuracy, with the evaluation of stents improving all the time. Importantly for the interventional cardiologist, it has evolved into a crucial tool assisting in the planning of both coronary and structural heart interventions, with transcatheter aortic valve implantation the most successful example. With its resemblance to IVUS in the capability to assess both the lumen and vessel wall, cardiac CT provides additional information on the composition of the lesion and reference segments which might allow accurate selection of devices, potentially leading to complete lesion coverage, less incomplete stent apposition, and larger postprocedural diameters. An understanding of the uses of CT and keeping up to date with evolving CT technology is critical for the interventional cardiologist as the use of CT continues to evolve and establish itself as an everyday adjunct to cardiac intervention.Answer questions and earn CME: https://wileyhealthlearning.com/Activity2/4193301/Activity.aspx
Role of cardiovascular magnetic resonance in interventional cardiology
Authors: Mavrogeni S. , Kolovou G. 
Published: March 2016

AbstractCardiovascular magnetic resonance (CMR) has the inherent capability to perform tissue characterization, assessment of disease severity, myocardial inflammation, ventricular function, perfusion and fibrosis without radiation exposure. All these advantages of CMR can be perfectly well applied in interventional cardiovascular magnetic resonance (iCMR) providing high‐quality images during interventional procedures. CMR, as an innovating imaging technique, can (1) provide reliable information about the pattern of myocardial perfusion‐fibrosis in both ischemic and non‐ischemic heart disease and (2) guide the traditional interventional procedures. iCMR, by using excellent tissue imaging, can create a surrogate for direct visualization and offer multiplanar views and real‐time functional imaging without ionizing radiation. These images can facilitate the utilization of interventional procedures and promote the innovation of new interventional approaches.Answer questions and earn CME: https://wileyhealthlearning.com/Activity2/4193437/Activity.aspx
Left atrial appendage occlusion for stroke prevention in patients with atrial fibrillation: indications diversity and future perspectives
Authors: Tzikas A. , Lewalter T. 
Published: March 2016

AbstractLeft atrial appendage occlusion (LAAO) is a promising alternative to oral anti‐coagulation in patients with non‐valvular atrial fibrillation. Recently, four‐year results of PROTECT‐AF demonstrated superiority of LAAO in all‐cause mortality and stroke reduction compared to optimal medical treatment with warfarin. In this new era, it is important to identify the patients who would benefit more from LAAO and offer them priority for treatment.Answer questions and earn CME: https://wileyhealthlearning.com/Activity2/4193475/Activity.aspx
Echocardiography in interventional cardiology
Authors: Henein M. Y. 
Published: March 2016

AbstractOver the last two decades, cardiology practice has experienced fast development of new interventional diagnostic and treatment procedures. While most procedures are cath lab based, the use of echocardiography as an imaging technique has become an integral part. In addition to the important use of transesophageal echocardiography in aortic and mitral valve surgery, it has now become an essential imaging technique for transcatheter aortic valve replacement and MitraClip procedures. Likewise, atrial septal procedures—whether hall closure or puncture for mitral valvuloplasty—are both performed under transesophageal echo guidance. Even ventricular procedures, for example alcohol septal reduction and pericardiocentesis, are performed under direct echo imaging. Thus, Doppler echocardiography has become an integral component of most cardiac procedures where operators need to have optimum skills as what to look for at different stages of the procedure.Answer questions and earn CME: https://wileyhealthlearning.com/Activity2/4193230/Activity.aspx
