Cardiac catheterization has greatly contributed to the progress made in the management of congenital heart diseases (CHD). Initially used in diagnosis, it allowed the understanding of heart diseases, their anatomy and hemodynamics. Gradually, the development of interventional cardiology has played a major role in the management of these malformations (Patent ductus arteriosus [PDA] and atrial septal defect [ASD] closure, pulmonary dilatation, percutaneous pulmonary valve implantation…). The development of such technology was made possible through the concomitant development of imaging techniques: fluoroscopy, ultrasound, MRI and CT...

BACKGROUND: The bioresorbable vascular scaffold (BRS) technology constitutes the new revolution of the coronary artery disease interventional treatment. Currently, three distinct types of BRSs are available but only one, the Absorb BVS, was on the market in 2013 when the Regional Commission for Medical Devices and the Cardiology and Cardiac Surgery Commission of the Emilia-Romagna Region drew up a technical and scientific essay to provide guidance for the introduction of BRS in public and affiliated health facilities...

BACKGROUND AND OBJECTIVES: Amblyopia, commonly known as "lazy eye," is poor vision in an eye from prolonged neurologic suppression. It is a major public health problem, afflicting up to 3.6% of children, and will lead to lifelong visual impairment if not identified and treated in early childhood. Traditional treatment methods, such as occluding or penalizing the good eye with eye patches or blurring eye drops, do not always yield satisfactory results. Newer methods have emerged, based on liquid crystal shutter glasses that intermittently occlude the better eye, or alternately occlude the two eyes, thus stimulating vision in the "lazy" eye...

During the past decades the healthcare systems have rapidly changed and today hospital care is primarily advocated for critical patients and acute treatments, for which laboratory test results are crucial and need to be always reported in predictably short turnaround time (TAT). Laboratories in the hospital setting can face this challenge by changing their organization from a compartmentalized laboratory department toward a decision making-based laboratory department. This requires the implementation of a core laboratory, that exploits total laboratory automation (TLA) using technological innovation in analytical platforms, track systems and information technology, including middleware, and a number of satellite specialized laboratory sections cooperating with care teams for specific medical conditions...

BACKGROUND AND PURPOSE: This study evaluated the use of an artificial intelligence platform on mobile devices in measuring and increasing medication adherence in stroke patients on anticoagulation therapy. The introduction of direct oral anticoagulants, while reducing the need for monitoring, have also placed pressure on patients to self-manage. Suboptimal adherence goes undetected as routine laboratory tests are not reliable indicators of adherence, placing patients at increased risk of stroke and bleeding...

Objective Laboratory studies have demonstrated that impact protectors (IP) used in motorcycle clothing can reduce fracture severities. While crash studies have reported IP are associated with reduced likelihood of soft tissue injury, there is little evidence of their effectiveness in reducing fracture likelihood. This discrepancy might be related to IP quality. There are mandatory requirements for IP supplied with protective clothing in Europe, but not elsewhere. This study examines the energy attenuation performance of IP used by Australian riders...

A 59-year-old man who had been previously diagnosed with congenitally corrected transposition of the great arteries at the age of 35 years became a candidate for heart transplantation. At the age of 57 years, he was referred to our hospital and underwent implantation of a left ventricular assist device (EVAHEART; Sun Medical Technology Research Corp., Suwa City, Japan) because of worsening ventricular function and was listed as a heart transplant candidate. A donor appeared when the patient was 59 years. A three-dimensional replica was made using data from computed tomography angiography...

BACKGROUND: Motion monitoring is essential when treating non-static tumours with pencil beam scanned protons. 4D medical imaging typically relies on the detected body surface displacement, considered as a surrogate of the patient's anatomical changes, a concept similarly applied by most motion mitigation techniques. In this study, we investigate benefits and pitfalls of optical and electromagnetic tracking, key technologies for non-invasive surface motion monitoring, in the specific environment of image-guided, gantry-based proton therapy...

Some cases of fungal infection remained undiagnosed, especially when the pathogens are uncommon, require specific conditions for in vitro growth, or when several microbial species are present in the specimen. Ultra-Deep Sequencing (UDS) could be considered as a precise tool in the identification of involved pathogens in order to upgrade patient treatment. In this study, we report the implementation of UDS technology in medical laboratory during the follow-up of an atypical fungal infection case. Thanks to UDS technology, we document the first case of gastro-intestinal basidiobolomycosis (GIB) due to Basidiobolus meristosporus...

Lei Mou, Xingyu Jiang
Conventional immunoassays suffer from at least one of these following limitations: long processing time, high costs, poor user-friendliness, technical complexity, poor sensitivity and specificity. Microfluidics, a technology characterized by the engineered manipulation of fluids in channels with characteristic lengthscale of tens of micrometers, has shown considerable promise for improving immunoassays that could overcome these limitations in medical diagnostics and biology research. The combination of microfluidics and immunoassay can detect biomarkers with faster assay time, reduced volumes of reagents, lower power requirements, and higher levels of integration and automation compared to traditional approaches...

Voriconazole is a triazole broad-spectrum antifungal medication often used to treat fungal infections caused by Aspergillus and Fusarium species. One of the main challenges associated with the implementation of this medication is its narrow therapeutic concentration range, demonstrating toxicity at concentrations above 6μg/mL and limited efficacy at concentrations below 2μg/mL. As a result, methodologies which permit the rapid and accurate quantitation of voriconazole in patients are highly desirable. In this work two different approaches based on coated blade spray directly coupled to mass spectrometry (CBS-MS) are introduced; each enabling the quantitation of voriconazole in plasma samples with a simple and fast sample preparation and no chromatographic step...

Recent advances in microsurgery, imaging, and transplantation have led to significant refinements in autologous reconstructive options; however, the morbidity of donor sites remains. This would be eliminated by successful clinical translation of tissue-engineered solutions into surgical practice. Plastic surgeons are uniquely placed to be intrinsically involved in the research and development of laboratory engineered tissues and their subsequent use. In this article, we present an overview of the field of tissue engineering, with the practicing plastic surgeon in mind...

Cardiovascular imaging is an integral component of many clinical trials beyond those for which the primary goal is to evaluate or validate imaging technologies. The scope of such trials is broad, ranging from those in which a medical, surgical, or interventional cardiovascular device or drug is being evaluated to those in which there is concern about cardiovascular adverse events complicating treatment for noncardiac conditions. This paper discusses study design as it pertains to the incorporation of imaging elements, the important role played by imaging core laboratories, the rationale for and approaches to involvement of imagers in clinical trials, and guidance by the U...

The National Blood Transfusion Service (NBTS) in England and Wales was established as a single entity in 1946 and operated as such for almost half a century. During those 50 years, the blood service in Wales, as in the rest of the UK, saw many technological and operational changes. The automation of donation testing, the introduction of successive layers of microbiological screening, the creation of the Tissue Typing Laboratory (later renamed the Welsh Transplantation and Immunogenetics Laboratory) and the development of information technology brought - over a relatively long period - highly significant improvements to an organisation that had begun life as an Emergency Medical Service...
