More pragmatic randomized studies with a focus on registry-based trials

Background Randomized controlled trials (RCTs) that are highly restrictive in terms of study design, with highly selected participants and conditions, produce results whose applicability to routine clinical care and usefulness for reimbursement decisions is sometimes questioned. Objectives In view of the background mentioned above, do more pragmatic RCTs and registry-based...

bioprinting tissue-like constructs capable of controlled, complex shape change

Where standard 3D printing uses a digital blueprint to manufacture an object out of materials like plastic or resin, 3D bioprinting manufactures biological parts and tissues out of living cells, or bioinks. A fourth dimension — shape transformation over time — can be achieved by incorporating materials that enable printed...

Spelling interface using intracortical signals enabled neurofeedback training

Spelling interface using intracortical signals in a completely locked-in patient enabled via auditory neurofeedback training Patients with amyotrophic lateral sclerosis (ALS) can lose all muscle-based routes of communication as motor neuron degeneration progresses, and ultimately, they may be left without any means of communication. Here, we implanted two 64 microelectrode...

Converting blood type A donor lungs into universal blood type lungs

Ex vivo enzymatic treatment converts blood type A donor lungs into universal blood type lungs A major challenge in lung transplantation is the need for ABO blood group matching. To address this challenge, Wang et al. used two enzymes, FpGalNAc deacetylase and FpGalactosaminidase, to convert blood group A lungs to blood group...

Biocompatible mini energy storage device for direct diagnosis in the body

Miniatur-Sensoren, die Vitalwerte direkt im Körper bestimmen sollen, sind hochkomplexe Systeme. Eine der größten Hürden stellt die Energieversorgung dar. An der TU Chemnitz haben Wissenschaftler jetzt Energiespeicher entwickelt, die zwar nur so groß wie ein Staubkorn sind, aber Spannungen vergleichbar mit einer AAA-Batterie liefern. Biosuperkondensatoren (BSCs)“. Sie besitzen zwei herausragende...

Visualization of USPIO-labeled melt-electrowritten scaffolds by non-invasive magnetic resonance imaging

Melt electrowriting (MEW) is a high-resolution fiber-forming technology for the digital fabrication of complex micro-structured scaffolds for tissue engineering, which has convincingly shown its potential in in vitro and in vivo animal studies. The clinical translation of such constructs to the patient requires the capability to visualize them upon implantation...

Research network in Hanover conducts research on intelligent implants

Researchers from a wide range of disciplines will work together to develop intelligent implant systems for the dental, skeletal and hearing areas, which for the first time will allow continuous monitoring of implant function and thus early detection of complications such as infections. Intelligent implant systems are to be developed...

Wissenschaftliche Untersuchung steril verpackter Medizinprodukte

100 original verpackte Zahnimplantate wurden mit einem Rasterelektronenmikroskop auf Rückstände untersucht. Folgende Materialien wurden gefunden: Metallische Partikel mit deutlichen Anteilen von Kupfer, Zinn, Chrom, Eisen, Wolfram und Nickel. Filmische Rückstände und kohlenstoffhaltige Partikel. Chemikalien wie z. B. Erucamid, Dodecylbenzolsulfonsäure. Der Autor diskutiert die medizinische Relevanz dieser Befunde. Author(s) Source Duddeck...

Scientific investigation of sterile packaged medical devices (german original)

100 originally packaged dental implants were examined for residues using a scanning electron microscope.  The following materials were found: Metallic particles with significant amounts of copper, tin, chromium, iron, tungsten and nickel. Filmic residues and carbon containing particles. Chemicals such as erucamide, dodecylbenzene sulfonic acid. The author discusses the medical...
