Newly developed “smart” coatings for surgical orthopedic implants can monitor strain on the devices to provide early warning of implant failures while killing infection-causing bacteria.
Arthroplasty for femoral neck fractures has seen enormous progress in recent years, but complications due to infections are still a major problem. With good preparation and the right technique, however, orthopaedic surgeons can take away much of the horror of this scenario.
A newly developed capsule that tunnels through mucus in the GI tract could be used to orally administer large protein drugs such as insulin.
A sprayable coating that can prevent the surface spread of infection from bacteria and viruses – including Covid-19 – over a sustained period has been developed by Australian researchers.
Hospital-acquired infections are dangerous for patients and costly for clinics. A novel surface treatment could help improve the safety of medical devices and ease the economic burden.
A new kind of bone implant reduces the chance of infection, and therefore significantly decreases implant failure rates.
Customizable to individual patients and requiring less than 10 minutes to prepare and use, new surgical implant coating prevented 100% of infections in mice.
Antimicrobial technologies such as coatings and textiles containing silver and copper are helping people during the Covid-19 pandemic by ensuring that whatever they touch, whether that is a door handle or their own mask, is free from live SARS-CoV-2 particles. But how exactly do these antimicrobial technologies work? How can a silver, copper or even polymeric coating kill microorganisms such as…
Potentially game-changing research led by McMaster University scientists may finally bring relief to millions of people worldwide living with Crohn’s disease. Investigator Brian Coombes said his team identified a strain of adherent-invasive E-coli (AIEC) that is strongly implicated in the condition and is often found in the intestines of people with Crohn’s disease. “If you examine the gut…
In the past few decades, researchers have identified biological pathways leading to neurodegenerative diseases and developed promising molecular agents to target them. However, the translation of these findings into clinically approved treatments has progressed at a much slower rate, in part because of the challenges scientists face in delivering therapeutics across the blood-brain barrier (BBB)…
Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a synthetic peptide that can make multidrug-resistant bacteria sensitive to antibiotics again when used together with traditional antibiotics, offering hope for the prospect of a combination treatment strategy to tackle certain antibiotic-tolerant infections.
Imagine a dressing that releases antibiotics on demand and absorbs excessive wound exudate at the same time. Researchers at Eindhoven University of Technology (TU/e) hope to achieve just that, by developing a smart coating that actively releases and absorbs multiple fluids, triggered by a radio signal. This material is not only beneficial for the healthcare industry, it is also very promising in…
People who are at high risk of developing lung cancer, such as heavy smokers, are routinely screened with computed tomography (CT), which can detect tumors in the lungs. However, this test has an extremely high rate of false positives, as it also picks up benign nodules in the lungs. Researchers at the Massachussetts Institute of Technology (MIT) have now developed a new approach to early…
Periprosthetic joint infection (PJI) is on the increase internationally. In Germany, for example, around 14,500 cases of PJI in hip and knee replacements occur annually. 5,100 of those are caused by multidrug resistant pathogens. ‘Eighty-seven percent of those affected die within five years,’ orthopaedic surgeon Professor Rudolf Ascherl MD pointed out during the Heraeus Symposium held at the…
Layering minute amounts of Manuka honey between layers of surgical mesh acts as a natural antibiotic that could prevent infection following an operation, new research has shown. Meshes are used to help promote soft tissue healing inside the body following surgery and are common in operations such as hernia repair. However, they carry with them an increased risk of infection as the bacteria are…
A material that is particularly toxic when bacteria are present in its environment? Physicists from the University of Augsburg, together with colleagues from Hamburg and Munich, have developed just such an "smart" coating. In the future, it could help prevent complications in the healing of endoprostheses. The coating also offers further advantages: It is extremely wear-resistant and…
In children, middle ear infections are the number one indication for antibiotic prescriptions or surgery. Nearly every child around the world will suffer at least one middle ear infection (otitis media) severe enough to see a doctor, and most will experience repeat occurrences throughout childhood. Internationally, there is significant over-prescription of antibiotics for otitis media, leading to…
Scientists have uncovered a novel antibiotic-free approach that could help prevent and treat one of the most widespread bacterial pathogens, using nanocapsules made of natural ingredients. Helicobacter pylori is a bacterial pathogen carried by 4.4 billion people worldwide, with the highest prevalence in Africa, Latin America and the Caribbean. Although the majority of infections show no symptoms,…
Hip and dental implant operations are routine. But not entirely risk-free. They may result in infection that is difficult to control with oral or intravenous antibiotics. In such cases, the implant will probably need to be replaced. Fraunhofer researchers can now apply a precisely matched drug directly to the replacement implant while significantly increasing the effectiveness of the antibiotic…
This year’s unexpectedly aggressive flu season reminds everyone that although the flu vaccine can reduce the number of people who contract the virus, it is still not 100 percent effective. Researchers report that a tweak to a small-molecule drug shows promise for future production of new antiviral therapies that could help patients, regardless of the strain with which they are infected. The…
Hospital-acquired infections are both a cause of and contribute to resistance, but a new technology can help.
Magnets instead of antibiotics could provide a possible new treatment method for blood infection. This involves the blood of patients being mixed with magnetic iron particles, which bind the bacteria to them after which they are removed from the blood using magnets. The initial laboratory tests at Empa in St. Gallen have been successful, and seem promising.
They may be slimy, but they are a perfect environment for microorganisms: biofilms. Protected against external influences, here bacteria can grow undisturbed, and trigger diseases. Scientists at Kiel University, in cooperation with colleagues at the Hamburg University of Technology (TUHH) in Hamburg-Harburg, are researching how it can be possible to prevent the formation of biofilms from the…
Wound infections after surgery are not uncommon and can be fatal. In Germany, postoperative wound infections are now the most common type of hospital acquired infection (HAI), with a proportion of 24%.
A research team led by University of Arkansas chemist Jingyi Chen and University of Arkansas for Medical Sciences microbiologist Mark Smeltzer has developed an alternative therapeutic approach to fighting antibiotic-resistant infections.
Australian researchers develop a new technique that tricks bacterial biofilms into dislodging from their protective matrix, making them vulnerable to treatment with antibiotics.
MRSA is bad news. If you've never heard of it, here's what you need to know: It's pronounced MER-suh, it's a nasty bacterial infection and it can cause serious disease and death. Senior molecular biology major Jacob Hatch knows MRSA as the infection that took his dad's leg.
The European Society of Clinical Microbiology and Infectious Disease (ESCMID) advocates the need for greater education, guidance and research on the build-up, treatment and prevention of biofilms, which contribute to antimicrobial resistance.
For all the advances being made in this discipline, postoperative infections remain a great challenge for orthopaedists and trauma surgeons. More than 7,000 experts from around the globe are gathering in Prague for the 16th EFORT Congress to consult on ways to optimise prevention and therapy for these dreaded complications.
A new extracorporeal nanotech device addresses the root cause of sepsis by removing pathogens and endotoxins simultaneously from blood even before their identification – this genetically engineered mannose-binding lectin protein can also latch on to the Ebola virus... Report: Cynthia E Keen

‘Better hygiene’ is the frequently and loudly recommended panacea in the intensifying struggle against hospital-acquired infections (HAIs). However there are currently no evidence-based studies that evaluate the efficacy of additional hygiene measures.
Worldwide, antibiotic resistance is one of the three major challenges for public health according to the European Society of Clinical Microbiology and Infectious Diseases (ESCMID). What needs to be done? Anja Behringer reports.
Post-operative wound infection occurs after an estimated 17% of surgical operations – sometimes with devastating consequences for the patient. The list of preventive measures is manifold and long. However, one strategy is increasingly moving into the spotlight: the use of antibacterial coated sutures. Ethicon Products is at the cutting edge in this field. Sandra Rasche, head of this Business…
A wound compress is being developed at the Hohenstein Institute in Boennigheim, Germany, that could pave the way for new treatment opportunities. The new wound compress would integrate and continually deliver effective ingredients on the basis of nanosol technology. The technique speeds up healing, simplifies treatment and reduces the amount of time required for care.
