Device for irregular heartbeat more cost-effective than medication
A new study by a Yale researcher may support the use of a device for patients suffering from irregular heart rhythms.

Drexel University scientists have discovered an unusual mechanism for how two new antimalarial drugs operate: They give the parasite’s skin a boost in cholesterol, making it unable to traverse the narrow labyrinths of the human bloodstream. The drugs also seem to trick the parasite into reproducing prematurely.

Conventional therapy for ARDS patients and for patients with exacerbation of chronic obstructive pulmonary disease (COPD) has relied on invasive mechanical ventilation. Mechanical ventilation, however, has several major drawbacks: sedation has to be induced and the air being pressed into the lungs with positive pressure can damage the pulmonary alveoli or the diaphragm. Moreover, even maximum…

Medical professionals have long known that the buildup of plaque in arteries can cause them to narrow and harden, potentially leading to a whole host of health problems — including heart attack, heart disease and stroke. While high blood pressure and artery stiffness are often associated with plaque buildup, new research from engineers at Washington University in St. Louis shows they are not…

A team from the International School for Advanced Studies (SISSA) in Trieste has obtained very promising results by applying gene therapy to glioblastoma. Tests in vitro and in vivo on mice provided very clear-cut results, and modelling demonstrates that the treatment targets at least six different points of tumour metabolism. Gene therapy, a technique that selectively attacks a tumour, might…

The mechanism by which drug-resistant bacteria maintain a defensive barrier has been identified by researchers at England’s University of East Anglia (UEA) and their findings could result in a new wave of drugs that can bring down those defensive walls rather than attack the bacteria – thus they may not develop drug-resistance at all.

Topics of big data, the genetic basis of coronary artery disease and sudden cardiac death in the young are among key subjects for British cardiologists at their 2016 annual conference. With a central theme of “Prediction and Prevention”, the 2016 British Cardiovascular Society annual conference takes place in Manchester from June 6-8 and features innovative and interactive presentations,…

Two new optical devices could reduce the need to take tissue samples during medical examinations and operations and to then send them for testing – potentially speeding up diagnosis and treatment and cutting healthcare costs.

The 13th Symposium of the European Academy of Dermatology and Venereology, which opened its doors last Thursday 19th May and took place in Athens, Greece, came to a conclusion yesterday, after more than 2,000 participants benefited from a series of scientific sessions focusing on the latest developments in Dermatology and Venereology.

The same 4K ultra-high-definition (UHD) technology that is surging as the next wave in consumer television has broken into the medical market with the presentation of two first-to-market laparoscopes.

Most accidents result from ‘the human factor’ – long acknowledged in aviation. Thus all crew members receive regular safety training to help prevent errors on board and on the ground. Now experts at the German Society for Orthopaedics and Trauma (DGOU) with those from Lufthansa Flight Training have developed a similar training programme for physicians. This Interpersonal Competence Training…

Pentax Medical launches a world first for endoscopy, the OPTIVISTA EPK-i7010 Video Processor, featuring both digital and optical enhancements, in the European, Middle Eastern & African (EMEA) markets. This unique enhancement combination provides detailed information for more accurate endoscopic in vivo diagnosis through improved vessel and mucosal pattern characterization.

The Materialise Mimics Care Suite is an open and flexible platform that includes planning and design software tools, 3D printed anatomical models and surgical guides, and patient-specific implants. Launched during AAOS, the American Association of Orthopaedic Surgeon’s Annual Meeting, the Suite also introduces Materialise Mimics inPrint, a new software solution that enables surgeons to create…

As scientists scramble to get a Zika virus vaccine into human trials by the end of the summer, a team of researchers is working on the first-ever vaccine to prevent another insect-borne disease – Leishmaniasis – from gaining a similar foothold in the Americas.

What started as a stuffy-nose and mild cold symptoms for 15-year-old Parker Turchan led to a far more serious diagnosis: a rare type of tumor in his nose and sinuses that extended through his skull near his brain. “He had always been a healthy kid, so we never imagined he had a tumor,” said Parker’s father, Karl. “We didn’t even know you could get a tumor in the back of your nose.”

A novel class of compounds developed by a University of Saskatchewan (U of S)-led research team could yield more effective and less toxic chemotherapy drugs to treat cancer. Team leader Jonathan Dimmock, a medicinal chemistry researcher in the U of S College of Pharmacy and Nutrition, explained their compounds work by interacting with thiols, naturally occurring chemicals that perform several…

Despite messages to the contrary, most women being seen by a doctor for the first time with suspected heart disease actually experience the same classic symptoms as men, notably chest pain and shortness of breath, according to a study led by the Duke Clinical Research Institute.

Every year, tens of millions of individuals across Europe undergo endoscopic procedures to assist with the diagnosis and management of gastrointestinal diseases. However, significant variation in current endoscopy provision across Europe has been reported, with back-to-back colonoscopy studies demonstrating that a concerning 22 percent of all adenomas are missed and that a three-to-six fold…

MedUni Vienna researchers have published the results of a clarifying research study on the potential transmissibility of Alzheimer’s disease. Although the protein associated with Alzheimer’s disease, amyloid-β, might be transmissible under very unusual circumstances, this does not go along with a transmission of the clinical manifestation of Alzheimer’s disease. The affected persons…

On March 3, Radiotherapy Group clinicians at Ziekenhuis Gelderse Vallei (Ede, the Netherlands) used their Esteya electronic brachytherapy system for the first time to treat a 73-year-old male patient with a nodular basal cell carcinoma on his nose. Esteya is a form of high dose rate (HDR) brachytherapy that applies high-precision radiotherapy directly to the cancer site, minimizing radiation to…

An amputee was able to feel smoothness and roughness in real-time with an artificial fingertip that was surgically connected to nerves in his upper arm. Moreover, the nerves of non-amputees can also be stimulated to feel roughness, without the need of surgery, meaning that prosthetic touch for amputees can now be developed and safely tested on intact individuals.

Magnetic resonance image isn't everything. A new University of Alberta study shows that vibrating the spine may reveal more when it comes to treating back pain. Teaming with the University of South Denmark to study the lumbar spine of twins, Greg Kawchuk and his team demonstrate that structural changes within the spine alter its vibration response significantly.

Bioengineers and physicians at the University of California, San Diego have developed a potential new therapy for critical limb ischemia, a condition that causes extremely poor circulation in the limbs and leads to an estimated 230,000 amputations every year in North America and Europe alone to prevent the spread of infection and tissue death. The new therapy could prevent or limit amputations…

Liposomes are currently used as drug delivery vehicles but recognized by the immune system. Scientists from the universities of Basel and Fribourg have shown that special artificial liposomes do not elicit any reaction in human and porcine sera as well as pigs. The study was published in the Journal Nanomedicine: Nanotechnology, Biology, and Medicine.

Following a meeting of professional organisations on the healthcare workforce implications on Antimicrobial Resistance (AMR) held at World Health Organization (WHO) headquarters on 2 March 2016, the International Council of Nurses calls on governments to support the Global Action Plan on AMR and stresses the key role of nurses in reducing the impact and limiting the spread of this major threat to…
