Stroke and Traumatic Brain Injury

Every 45 seconds, someone suffers a stroke in the United States. Each year, 1.7 million people suffer a traumatic brain injury (TBI) in the United States.  A stroke results from an artery bursting, leaking, or becoming obstructed, which deprives the brain of oxygen and leads to cell death. A traumatic brain injury results from a blow to the head or a penetrating brain injury that disturbs the brain’s normal functions. Fortunately, a medical breakthrough has been made that may restore some brain function, even if years have gone by since the stroke or traumatic event.

Researchers at the Institute of Neurological Recovery (INR) discovered that one dose of etanercept can quickly improve neurological problems caused by a stroke or traumatic brain injury. Etanercept works by binding to and deactivating an immune molecule that is responsible for excessive brain inflammation. An observational study conducted involving 629 patients demonstrated the potency of this claim. Most of the patients experienced significantly rapid improvement in cognition, motor impairment, and spasticity, after receiving a dose of etanercept. The study was carried out long after spontaneous meaningful recovery would be likely.

In the years to come, this groundbreaking discovery may have a dramatic impact. People left severely debilitated after suffering a stroke or traumatic brain injury may finally be able to resume their normal lives. Also, countless lives may be spared, if a person receives a dose of etanercept, before the damage progresses too far.  People from all around the world, not just the United States, may greatly benefit from this medical discovery.

Duchenne Muscular Dystrophy and Assist Devices

Duchenne muscular dystrophy is an inherited disease that weakens the muscles of the body (Tortora 2012). Each year, approximately 2,500 people around the world are born with this devastating disorder. It affects mostly males, and many patients are confined to a wheelchair before the age of 12. Most of them are dead by their late teens or early 20s. All patients who manage to survive to the age of 21 develop a heart disease known as dilated cardiomyopathy that ensures their demise. Fortunately, a new invention may be a breakthrough in the treatment of the disease.

The Cincinnati Children’s Heart Institute has developed a ventricular assist device that is designed to help a weakened heart pump blood to other parts of the body. Though these devices are relatively new and still in the experimental stage, it did not deter Jason Williams, a 29 year old with Duchenne muscular dystrophy, from being the first patient to have one implanted in his chest. It was actually one of his only hopes for prolonging his survival, since Duchenne muscular dystrophy patients are not candidates for heart transplants or other treatment options available to patients with other kinds of muscular dystrophy. Doctors plan to monitor the device’s effect on Williams, in order to determine if it should be made available to others with the disease.

Ventricular assist devices could enable thousands of men born with Duchenne muscular dystrophy each year to live better lives. No longer would they have to endure the agony of their bodies slowly shutting down. Their hearts would be able to function properly, and they would not succumb to the disease. Many men might finally get to experience the joys of growing old and leading normal lives.

Moles and Mesothelioma

Nevi, more commonly known as moles, are chronic lesions of the skin. They usually form during childhood or adolescence and are the result from melanocytes growing in clumps, instead of being evenly distributed throughout the skin. Moles can be raised or flat and are typically benign and symmetrically shaped. Most people think moles serve no purpose and regard them as nothing more than an annoyance. However, new research says they might alert people of their risk of developing mesothelioma, a potentially life-threatening cancer of the mesothelial membranes that envelop and protect internal organs.

Researchers at the University of Hawaii, one of the most renowned mesothelioma research centers in the world, have discovered a type of mole present on people who have a genetic mutation on the BAP1 gene.  This mole is known as a melanocytic BAP1-mutated atypical intradermal tumor or MBAIT. Although its unique characteristics can only be identified by biopsy and examination by a pathologist, patients and doctors are encouraged to monitor skin changes that may signify a risk for mesothelioma.

This research might stop people from regarding moles as a merely beauty blemishes. They may come to realize that some moles are a significant indicator of deadly cancers. Though only medical experts can distinguish those types of moles from ordinary moles, they should become more aware and cautious of any that they might have. Thanks to these findings, people might have their moles more frequently examined by doctors, leading to early cancer detection and more saved lives.

Stem Cells Give Injured People New Hope

In recent years, stem cell research has been gradually growing more prominent. Researchers speculate that stem cells, which are unspecialized cells, may possibly treat or cure certain health conditions. However, this notion is still being met with some disinterest and skepticism. Almost a year ago, Geron of Menlo Park, California ceased its stem cell programs that were supposed to fight serious ailments, such as arthritis, cardiovascular disease, and diabetes.  Also, Geron halted experiments intended to test cell therapy as a treatment for spinal injuries.  However, thanks to StemCells, a company in Newark, California, studies have been revived to test the possible benefits stem cells might have on spinal damage.

In a recent clinical trial, three people were injected with millions of stem cells at the site of their spinal injury. After six months passed, two of the three subjects reported that they had begun to regain sensation. When exposed to heat and gentle touch, their responses were nearly equal to those of an uninjured person. Nine more people with less severe paralysis are scheduled to receive the treatment. Though the signs are encouraging, researchers insist that further analysis is needed before they can conclude that stem cells have a definite future in healing.

The use of stem cells has the potential to become one of the most important medical techniques in history. Stem cells could be used to regenerate a variety of cells harmed or destroyed, after a physical trauma is suffered. Countless lives could be saved, and many people who have been deprived of their independence and well-being could have the opportunity to be restored. While these things would not come about overnight, they are becoming closer to being a reality.
