New biodegradable nanofibre bandage enables faster healing

An international team of scientists has developed a new bandage with a strong antibacterial effect and which can be kept on over long periods of time without needing to be changed, thereby accelerating skin regrowth and reducing the risk of infection. The new dressing material has great potential for future application in the healing of wounds, does not require changing, and can literally be put on over top of one another as they degrade, the Sputnik news agency reported.

The traditional use of an antiseptic in the treatment of wounds, consisting of washing the affected area with a solution and using gauze dressing to increase the outflow of fluids, repeated several times.
However, such treatment, particularly the use of antibiotics kill not only dangerous bacteria but also the useful bacteria. And when dressings are changed, the fragile area undergoing healing is disturbed, causing severe pain to patients.

But according to scientists, the new biocompatible dressing material can act locally on the area of inflammation. As the material slowly releases their antibiotic, the dressings gradually dissolve on the skin.

The material was made using polycaprolactone nanofibres -- a biocompactable, bioresabsorable material -- and attached gentamicin, a broad-spectrum antibiotic, to the fibres.

"What we found was that the action was prolonged: we observed a significant decrease in the number of bacteria even 48 hours after the material was applied," a researcher was quoted as saying.

"Usually, surfaces with an antibacterial effect fulfill their potential within the first day or even the first hours of use," the researcher  explained. In the study, reported in the Materials and Design academic journal, the team performed experiments using three strains of E. coli bacteria, with the strains showing varying levels of resistance to the antibiotics, but nonetheless combated against effectively by the dressing.

The new material is potentially applicable not only for treatment to heal skin, but to treat inflammatory bone diseases such as osteoporosis and osteomyelitis, the report noted.

7 Things Your Back Pain Is Trying to Tell You

Pain is our body's way of telling us that something is wrong. In the case of back pain, the root cause may be obvious - you may have been involved in a car accident, or lifted a box that was too heavy. Though it may also seem like a mystery. Nevertheless, if you dig a little, the root cause of your back pain could also be sorted out. So if you're unsure about why you are in agony, one of these 7 possible causes may be it: 

 

1. You're feeling stressed It should come as no surprise to learn that stress can cause tight muscles and knots in your neck and upper back. Anxiety may also cause you to have back spasms too. If you suspect that stress is causing you back pain, try to incorporate some relaxation techniques such as meditation and deep breathing into your routine. A weekly yoga class, or an intensive stretch will help reduce lower back pain. 

2. You're hooked on technology Hunching over a phone or tablet for several hours a day can cause what has now been termed, 'text neck'. Having a slumped neck and rounded shoulders adds an additional 60 pounds of weight on your spine, which can inadvertently change your posture and cause back pain. To prevent this from happening, try keeping your phone at eye level instead. 

3. You're not sitting properly Just as looking down at your smartphone can cause back problems, sitting down all day can wreck havoc on your spine too. Poor posture can cause lower back pain by increasing the amount of pressure or tension on the bones, joints, ligaments, and spinal discs. Improve your sitting posture by keeping your forearms parallel to the floor, your head in line with your torso, your feet flat on the floor or resting on a foot rest, your back fully supported and thighs parallel to the floor. 

4. You have a muscle imbalance elsewhere in your body Everything in your body is interconnected. Your back pain may be stemming from tight hamstrings or weak abdominal. If other muscle groups are weak, it can cause the muscles of the back to do more work than they should to keep the spine upright or moving correctly. Try working with a physical therapist to identify and correct the specific imbalances that are over-taxing your back.

 

5. You have a bulging or ruptured disc The disks between your vertebrae help cushion the spine and act as shock-absorbers. Over time, however, they can flatten or rupture due to natural aging, certain movements, or a family history of disc disease. While it doesn't always cause pain, when it does, it can be hugely uncomfortable. If a bulging disc is the culprit, doctors often prescribe over-the-counter medicine, hot and cold packs, and physical therapy. 

6. Something more serious is going on Pancreatitis, ulcers, or even a kidney infection could cause pain that radiates into the back. It may also be a result of an infection, osteomyelitis - an infection of the spine. Most back pains tend to resolve on their own in six weeks - but if yours has gotten worse then be sure to see a physician, particularly if it is accompanied by fever, numbness in the rectal area, and loss of bowel or bladder control. 

7. You just had a baby Statistics show that almost 80% of new moms suffer from lower back pain as a result of the stress placed on the body during pregnancy. Another cause may also be due to the habits that result from caring for a young baby, such as holding a baby on one side of the body, or hunching while nursing - which can lead to muscle imbalance, affecting the natural curve of your spine. Are you a new mom? Try be aware of maintaining good posture by alternating muscle groups so you're not constantly rocking, swaying, or bouncing your baby on one side.
