Transcatheter aortic valve implantation in patients with small aortic annuli using a 20 mm balloon-expanding valve

Background While transcatheter aortic valve implantation (TAVI) is established for treating highoperative risk surgical aortic valve replacement candidates, until recently the smallest transcatheter heart valve (THV) measured 23 mm, posing greater risk for annular rupture and THV failure in patients with aortic stenosis (AS) with small aortic annuli (=20 mm). Objectives In the setting of a multice

Control considerations of the low cost prosthetic Touch Hand

The control of the Touch Hand: a low-cost electrically powered prosthetic hand is explored in this paper. A novel Haptic User Interface is proposed and tested as a supplement for amputee-prosthetic EMG control. The performance of the prosthetic hand is tested through gripping tests. The hand is capable of performing a lateral grip of 3.7 N, a power grip of 19.5 N and to passively hold a weight of

Electronic ground state of Ni 2 +

The Φ9/24 ground state of the Ni2+ diatomic molecular cation is determined experimentally from temperature and magnetic-field-dependent x-ray magnetic circular dichroism spectroscopy in a cryogenic ion trap, where an electronic and rotational temperature of 7.4±0.2 K was reached by buffer gas cooling of the molecular ion. The contribution of the spin dipole operator to the x-ray magnetic circular

Efficacy and Toxicity of Intrathecal Liposomal Cytarabine in First-line Therapy of Childhood Acute Lymphoblastic Leukemia

We investigated efficacy and toxicity of replacing conventional triple (cytarabine, methotrexate, and hydrocortisone) intrathecal therapy (TIT) with liposomal cytarabine during maintenance therapy among 40 acute lymphoblastic leukemia patients. Twenty-eight of 29 patients in the TIT arm received TIT and 9/11 in the liposomal cytarabine arm received liposomal cytarabine. Arachnoiditis occurred in a

Attractive ion-ion correlation forces and the dielectric approximation

We analyze the classical problem of the interaction between two charged surfaces separated by a solution containing neutralizing counter-ions. The focus is on obtaining a description where the solvent is treated explicitly rather than through a dielectric approximation as is conventionally done. We summarize the results of three papers where we have used a Stockmayer fluid model in Monte Carlo sim

Introduction : Why the Nordic region?

The Nordic region is much admired around the world, but how much of what we know about these countries has been shaped by their adoption of placebranding and public diplomacy techniques? This collection of academic articles and practitioner essays digs beneath the veneer of their branding and PD practices to investigate not just the best practice of how the Nordic region has successfully projected

Unfractionated heparin versus bivalirudin in patients undergoing primary percutaneous coronary intervention : A SWEDEHEART study

Aims: The aim of the study was to compare outcomes in unfractionated heparin (UFH) and bivalirudin-treated patients undergoing primary percutaneous coronary intervention (PPCI). Methods and results: This observational study contained 20,612 PPCI patients treated with either UFH monotherapy or bivalirudin with or without concomitant UFH. Patients with oral anticoagulant or glycoprotein IIb/IIIa inh

A cardiac catheterisation laboratory core curriculum for the continuing professional development of nurses and allied health professions : Developed by the Education working group of the Nurses and Allied Professions Committee for the European Association of Percutaneous Cardiovascular Interventions (EAPCI) 2016

Aims: The aim of this report is to provide a standard educational structure for nurses and allied professionals (NAP) specialising in interventional cardiology. The curriculum can also be used as a basis for training on a certificate-based level in interventional cardiology. Methods and results: The curriculum was developed by a panel of experts from various allied health professions. The syllabus

Effect on mother and child of eculizumab given before caesarean section in a patient with severe antiphospholipid syndrome

Rationale: Antiphospholipid syndrome (APS) in pregnancy may trigger the life-threatening catastrophic antiphospholipid syndrome (CAPS). Complement activation is implicated in the pathogenesis, and inhibition of complement factor C5 is suggested as an additional treatment option. Patient concerns, diagnosis and interventions: We present a pregnant patient treated with the C5-inhibitor eculizumab du

The effect of voice quality and competing speakers in a passage comprehension task : perceived effort in relation to cognitive functioning and performance in children with normal hearing

The study investigates the effect of voice quality and competing speakers on perceived effort in a passage comprehension task in relation to cognitive functioning. In addition, it explores if perceived effort was related to performance. A total of 49 children (aged 7:03 to 12:02 years) with normal hearing participated. The children performed an auditory passage comprehension task presented with si

Judgments of warmth and competence in a computerized paradigm: Little evidence of proposed impression formation asymmetries

Much of what we know concerning impression formation is based on experimental methods where the participant receives a list of traits or behaviors and is asked to make trait judgments or meta-cognitive judgments. The present study aimed to put some well-known effects from the impression formation literature to a test in a more dynamic computerized environment, more akin to many real world impressi

The archaeology of teaching and the evolution of homo docens

Teaching is present in all human societies, while within other species it is very limited. Something happened during the evolution of Homo sapiens that also made us Homo docens-the teaching animal. Based on discussions of animal and hominin learning, we analyze the evolution of intentional teaching by a series of levels that require increasing capacities of mind reading and communication on the pa

Measurement-based analysis of relaying performance for vehicle-to-vehicle communications with large vehicle obstructions

It has been widely recognized that relaying is an important method for increasing the reliability and spectral efficiency of communications systems, and it is thus helpful for improving the performance of vehicle-to-vehicle (V2V) communication systems. However, designing and evaluating V2V relay networks require understanding the effect of shadowing, as this critically impacts the performance of t

Genetic diversity and evolution in eukaryotic phytoplankton : Revelations from population genetic studies

Eukaryotic phytoplankton exhibit an enormous species richness, displaying a range of phylogenetic, morphological and physiological diversity. Yet, until recently, very little was known about the diversity, genetic variation and evolutionary processes within species and populations. An approach to explore this diversity and to understand evolution of phytoplankton is to use population genetics as a
