Can Aging Be Cured?

Aubrey de Grey, MA, PhD, believes the coming decades will bring us anti-aging medicine that is at the same level of medical control as any other infectious disease. How similar is aging to other health problems, and can medical science really “fix” it? Watch as Aubrey de Grey offers a definition of aging that refocuses the question of whether or not it can be delayed or even reversed. Filmed at FutureMed, in February, 2012, at Singularity University. Featured image from Flickr |...

Can Spinach Leaves Replace Damaged Cardiac Tissue?

Featured From The Doctor’s Channel     Perfusion decellularization has recently been used to remove genetic material in pig organs, allowing them to be seeded with human stem cells in the hopes of securing a renewable source of organs for transplantation. In a similar (but non-mammalian) vein, researchers from the Myocardial Regeneration Lab at Worcester Polytechnic Institute have performed decellularization processes on spinach leaves and infused them with human heart muscle cells to determine if the remaining cellulose scaffold could support the demanding job of replacing dense heart tissue. The spinach-heart combinations were able to beat for up to three weeks in some of the experiments.   Next steps in this research include more in-depth testing of the compatibility of cellulose with human heart tissue, as well as “stacking” the plant-derived material to determine if layering the decellularized spinach leaves will yield “tissue” strong enough to maintain efficacy over long periods of time. The team, led by Glenn Gaudette, PhD, and Joshua Gershlak, MSc, have already begun testing other abundant plant species for viable veinous networks.   Click here to read an article about this research in the Washington Post.   Click here for the paper published in the journal Biomaterials via ScienceDirect.   Featured Image:...

Quiz! Do You Know Your Diseases?

As a medical practitioner, you need to be able to look at symptoms to help you diagnose a patient. It can be difficult without a full examination but some indicators can help you guess the most likely disease. Do you think you could diagnose correctly? Are you the next Dr House? The next medical Sherlock Holmes? Let’s find out! Featured From Gap Medics Blog Featured Image:...

Can Smartphones Sequence DNA?

Featured From The Doctor’s Channel   Video: Source   Molecular analysis of biological samples is typically outsourced to well-equipped (and cost-intensive) laboratories. However, there are times when sample diagnosis and DNA sequencing is needed quickly, needed in a remote location, or both. For this reason, Professor Mats Nilsson of Stockholm Universitet, Uppsala Universitet, and SciLifelab has led research on creating a smartphone compatible device for rapid, cost-effective molecular analysis.   The 3d-printed smartphone attachment uses a specialized lens and two LED lights to perform its microscopy. One of the first use-cases that Prof. Nilsson envisions for the technology is identifying antibiotic resistance in tuberculosis in developing countries. When the device becomes widely available, it’s estimated that it will cost less than $500.   Click here to read the paper published in the journal Nature Communications.   Featured Image:...

Can Punishing Medical Errors Make Hospitals Safer?

In January, Medicare cut federal payments to 769 hospitals, continuing a program of punishing hospitals for errors and avoidable complications, such as blood clots, falls and bed sores. For the first time these penalties also included hospital-acquired antibiotic-resistant infections. Mandated by the Affordable Care Act, Medicare is required to penalize the bottom 25% of the worst performing hospitals, even if they’ve shown a reduced rate of incidents from year to year. In the years since the penalties took effect, they had the unintended consequence of disproportionately reducing funding in teaching hospitals and for patients in low-income areas with limited access to services. This prompted congress to legislate a socioeconomic adjustment when evaluating hospital performance.   While the federal Agency for Healthcare Research and Quality (AHRQ) estimates that hospital-acquired conditions have declined 21% from 2010 to 2015, there were still an estimated 3.8 million hospital injuries in 2016: 115 injuries for every 1,000 patient stays. Specialized hospitals, such as those for children, rehabilitation, cancer, veterans and psychiatric treatment are exempt from the financial penalties.   Reporting by the Kaiser Family Foundation has found that readmission rates started falling in 2012 and have continued, suggesting that more hospitals have taken up preventative measures for hospital acquired infections and preventable readmissions, and that overall the impact of the penalties is less than 1% of the reimbursable amount for a re-admission.   Image:...

Diagnosing Genetic Disorders with Facial Recognition Technology

With advancing technology, you can see a doctor from home using FaceTime or send a pic of your mole for a cancer diagnosis. And now, the same technology that automatically tags your photos on Facebook can help doctors diagnose rare genetic diseases.   Facial recognition technology dates all the way back to 1964, when computer programmers starting teaching their computers how to recognize human faces. Early operations could process about 40 pictures an hour in an attempt to match similar features using coordinates between pupils, outside corners of the eyes, hairline, etc. Early attempts struggled to cope with variations from photo to photo if the subject wasn’t posed in exactly the same position. In the mid-2000s, the Face Recognition Grand Challenge was sponsored by the FBI and Department of Homeland Security, among others, to bring attention and innovation to facial recognition technology.   Image: Source   Now, researchers at the National Human Genome Research Institute (NHGRI) have produced software that uses facial recognition technology to help diagnose DiGeorge syndrome. A rare genetic disease, DiGeorge syndrome is caused by a defect in chromosome 22. Although its effects vary from person to person, the syndrome can result in cleft palate, low calcium levels, heart defects and a weakened immune system. There is no cure, but early interventions can improve the patient’s outlook through relevant treatments.   The breakthrough is particularly important...
