21/01/2019In the largest study to date of rapid TB tests used by the NHS, a team led by researchers at Imperial College London found that available tests are not sensitive enough to rule out a diagnosis of TB in suspected cases, and so have limited clinical use.
21/01/2019Pilot study by Brigham investigators finds that an innovative care-delivery program helped 81 percent of participants achieve blood pressure control in seven weeks.
11/01/2019With the help of sponges inserted in the bloodstream to absorb excess drugs, doctors are hoping to prevent the dangerous side effects of toxic chemotherapy agents or even deliver higher doses to knock back tumors, like liver cancer, that don't respond to more benign treatments.
08/01/2019When people are in the early stages of an undiagnosed disease, immediate tests that lead to treatment are the best first steps. But a blood draw - usually performed by a medical professional armed with an uncomfortably large needle - might not be quickest, least painful or most effective method, according to new research.
20/12/2018Buruli ulcer is a neglected tropical disease (NTD) resulting in debilitating skin lesions, disabilities and stigmatisation. The current antibiotic treatment is long and has severe adverse side effects.
19/12/2018Does expansion microscopy deliver true-to-life images of cellular structures? That was not sure yet. A new publication in "Nature Methods" shows for the first time that the method actually works reliably.
18/12/2018Tools allow scientists to understand the activity of naturally occurring microbiomes in response to real-world conditions and diet
18/12/2018Researchers find an effective way to treat an underdiagnosed condition that can cause heart attack and heart-attack-like symptoms.
17/12/2018Collagen is the fundamental building block of muscles, tissues, tendons, and ligaments in mammals. It is also widely used in reconstructive and cosmetic surgery. Although scientists have a good understanding about how it behaves at the tissue-level, some key mechanical properties of collagen at the nanoscale still remain elusive.
14/12/2018Researchers at Stanley Manne Children's Research Institute at Ann & Robert H. Lurie Children's Hospital of Chicago used a blood test and microarray technology to identify distinct molecular signatures in children with cystic fibrosis. These patterns of gene expression could help predict disease severity and treatment response, and lead to therapies tailored to each patient's precise biology.
06/12/2018The wonders of graphene are numerous. Now, the "supermaterial" may one day be used to test for amyotrophic lateral sclerosis, or ALS – a progressive, neurodegenerative disease which is diagnosed mostly by ruling out other disorders, according to new research from the University of Illinois at Chicago published in ACS Applied Materials & Interfaces.
05/12/2018Biomedical engineers have developed a smartphone app for the non-invasive detection of anemia. Instead of a blood test, the app uses photos of someone's fingernails taken on a smartphone to accurately measure how much hemoglobin is in their blood.
16/11/2018Purdue University researchers have developed a technology aimed at making it easier to deliver cancer treatment to the right "address" in the body while also easing the painful side effects of chemotherapy on patients. One of the big issues with chemotherapy is that most treatment approaches focus on the tumor itself without paying attention to the microenvironment surrounding the tumor.
16/11/2018Duke and Duke Kunshan University collaborating with InDevR Inc. to test the new influenza subtyping assay for enhanced surveillance.
08/11/2018A new flexible sensor developed by engineers at the University of California, Berkeley, can map blood-oxygen levels over large areas of skin, tissue and organs, potentially giving doctors a new way to monitor healing wounds in real time.
02/11/2018This is what diagnostic investigation normally looks like: a patient sample is collected, sent to the laboratory and analyzed. Once that's completed, the patient is told of the lab test result. But if the patient is a high-performance athlete and has to follow and stick to a rigid training schedule, he or she needs these results immediately. What makes this possible? Point-of-care testing!
24/10/2018Researchers at McMaster University have solved a vexing problem by engineering surface coatings that can repel everything, such as bacteria, viruses and living cells, but can be modified to permit beneficial exceptions.
22/06/2018A drop of blood provides a lot of valuable information. However, it takes several hours to analyze the blood of a patient and make a diagnosis. This takes away a lot of time that's crucial for treatment. A new method intends to considerably speed up this process by testing the cells in the blood in terms of their deformability and immune response.
20/12/2017Sixty percent of newborns are affected by jaundice during their first days of life. In most cases, the condition is harmless. The ailment is more pronounced in premature babies, whose treatment involves irradiation with blue light in a special incubator – naked and alone.
01/08/2017Advances in technology and analysis techniques, as well as the increasing miniaturization of laboratory equipment and processes, make it possible: patient-side laboratory testing, better known as point-of-care testing or POCT. There are many POCT projects and all of them promise a rapid diagnosis as well as economic advantages. But are these tests also suited for everyday medical testing?
01/08/2017Many therapeutic drugs are very powerful, but they are also very toxic at the same time. Thus, they have to be measured regularly, again and again, so that an adjustment of the individual drug dosage can be made. Until now, the "normal" way was to take the blood sample, send it to a central laboratory and get the results after some days. A new point-of-care test can measure it in 15 minutes.
24/07/2017A new analysis method that uses fetal DNA extracted from the mother’s blood is designed to non-invasively reach a prenatal diagnosis of genetic disorders in a child. A task force of the Hahn Schickard Society for Applied Research is an active part of the "ANGELab" project and co-developed this diagnostic procedure.
01/06/2016Some hospitals have long banned the status symbol of physicians – the white coat. Research has shown that especially the sleeves were contaminated with various types of bacteria. But it’s not just lab coats that can spread germs in healthcare settings. This field uses a variety of different textiles. Wouldn’t it, therefore, make sense to apply antimicrobial finishes?
22/05/2016The treatment for diabetes is very time-consuming for patients: they need to regularly monitor blood sugar levels, take medication and inject insulin. Poor self-management may result in a dangerous lapse in blood glucose levels. Yet external factors can also contribute to diabetes being out of control. An artificial pancreas system could offer relief.
22/03/2016Medical apps like diabetes or high blood pressure diaries are becoming increasingly popular with smartphone users. There are many available choices out there but they are not always clear. Added to this is the question of how the data collected by the apps can be sensibly incorporated into treatment.
08/03/2016Pancreatic cancer is one of the deadliest forms of cancer because it is difficult to diagnose and only presents with symptoms in the later stages. In the future, a laboratory test developed at the Greifswald University Medicine could make an early detection of this type of cancer and consequently a faster and better treatment possible.
01/02/2016First grow tissue in the lab, then insert it into patients when they need it and you’re done! Unfortunately, things are not as easy as people hoped at the onset of “tissue engineering”. Although robust tissues for bone defects can be grown in a petri dish, for example, they unfortunately quickly die off again inside the body if there is no corresponding nutrient supply.
01/02/2016Children, especially newborns, are generally no longer simply considered to be small adults whose treatment just needs to be "reduced". This is why a pediatrician’s education includes several specialties because ultimately everything in terms of care comes together here.
01/02/2016Self-healing powers like a superhero on the big screen? That’s the aim of regenerative medicine; at least in a very broad sense. This promising field of biomedicine is currently highly dynamic with innovative technologies and development. New methods are designed to help propel medicine into a whole new sphere.
04/01/2016Most Europeans think it was a long time ago, but the residents of West Africa clearly feel the consequences of the Ebola epidemic that broke out in December 2013 and still continues today. So far, approximately 11,300 people have died as a result of the outbreak; more than 28,000 contracted the disease.
04/01/2016When infectious diseases such as Ebola break out, a rapid diagnosis is important because the early detection of a virus along with the right hygiene measures can prevent its continued spread. However, laboratories and skilled personnel are not available everywhere. Low-cost and portable detection strips can bring relief.
01/12/2015Each year, approximately 250,000 Germans suffer a stroke. This makes stroke the third leading cause of death after heart disease and cancer. The circulatory disorder that occurs in the brain is normally treated using systemic thrombolysis, a procedure that bears various risks. Unlike mechanical thrombectomy, which offers clear advantages by comparison.
01/07/2015Deep vein thrombosis is not just a risk factor for frequent flyers but also for wearers of cardiovascular implants and newly operated patients. Blood thinners prevent these dangerous blood clots from forming, but they need to be carefully adjusted and do not work the same way in every patient. A detailed analysis of platelets (thrombocytes) could prevent complications in the future.
01/06/2015Can liquid biopsies become the new trend in cancer diagnostics? The medical world has asked this question for quite some time. The first globally approved liquid biopsy-based test for lung cancer shows that this can work. Yet further findings and research are still required to establish this less invasive method in diagnostics.
01/10/2014On November 10, 2014, astronaut Alexander Gerst will return to Earth from the International Space Station (ISS). He is not just anxiously expected by his family, but also by Dr. Anna-Maria Liphardt from the Institute of Biomechanics and Orthopedics at the German Sport University Cologne
02/06/2014"Sports are good for your health", as the saying goes. Regular exercise promotes the health of our blood vessels and prevents vascular diseases. However, many years of competitive sports can also have negative effects on vascular health and increase the risk of myocardial infarction. Prof. Martin Halle of the Technical University Munich explains at MEDICA.de what athletes need to pay attention to.
