What Will Medical Technology Look Like in 2025?

Take a trip to the future of medicine in these excerpts from TED Talks. What might 2025 hold? Patient-specific pluripotent stem cell lines stored in the freezer until they’re needed for regenerative therapy. Medical devices embedded in clothing that send signals when something goes wrong. Patients taking ownership of their own bodies and their own data. And nanotechnologies to detect and treat cancer. The brave new world may also be a healthier world. From Induced pluripotent stem cells. A new resource in modern medicine: Pluripotent stem cells possess a remarkable unlimited self-renewal capacity and offer unparalleled in vitro differentiation potential. This provides a unique model system not only to study early human development but also gives renewed hope in terms of developing cell therapies and regenerative medicine. S. Yamanaka, a medical doctor and researcher, reported the possibility of reprogramming somatic cells to so-called induced pluripotent stem cells via the ectopic expression of four transcription factors, namely Oct4, Sox2, Klf4 and c-Myc. This Nobel Prize winning work has since revolutionized stem cell research and paved the way for countless new avenues within regenerative medicine. This includes disease modeling in a patient-specific context with the ultimate aim of individually tailored pharmaceutical therapy. Additionally, genetic correction studies have rapidly increased in basic science and thus there is hope that these can be effectively and efficiently translated into clinical applications. Addressing the medical...

Virtual Reality is the Future of Medicine

What does it really feel like to manage an emergency in the operating room? The Cleveland Clinic Department of Thoracic and Cardiovascular Surgery is using virtual reality (VR) simulations of OR cardiac emergencies to replicate the experience as closely as possible and train cardiac surgery residents. “The two-minute video shows how Cleveland Clinic is using virtual reality scenarios to teach cardiac surgery residents how to maintain ideal performance under the pressure of OR crises.” The VR simulations incorporate scenarios from real operations to create an immersive, realistic, 360-degree experience that includes the viewpoints of multiple members of the surgical team. The scenarios map right decisions, wrong decisions, and their consequences. This video, narrated by Douglas Johnston, MD, the cardiac surgeon who heads the program, shows the scenario of a patient who has gone into ventricular fibrillation as seen through the VR headset of a surgical resident. From the study on pubmed.gov: The traditional system of clinical education in emergency medicine relies on practicing diagnostic, therapeutic, and procedural skills on live patients. The ethical, financial, and practical weaknesses of this system are well recognized, but the alternatives that have been explored to date have shown even greater flaws. However, ongoing progress in the area of virtual reality and computer-enhanced simulation is now providing educational applications that show tremendous promise in overcoming most of the deficiencies associated with live-patient training. It will...

Helping Mice Mate: 3D Printing Ovarian Envelopes

Northwestern University researchers have tested various 3d printing techniques to discover the angles at which ovarian follicles will optimally interact with their scaffolds to increase ovary survival. 30º and 60º angles apparently provide better protection and vascularization than 90º angles. The results have been harnessed to create a prosthetic implant that is meant to help restore fertility. Sterile mice implanted with these new follicle-infused scaffolds were able to reproduce through natural mating processes. The hope for the future of this research is to provide renewed fertility to female cancer patients rendered sterile by their therapies. The ovarian bioprosthesis may also hold the key to restoring and/or improving hormone production, which has many applications, including enabling young patients to proceed naturally through puberty. Click here to review the publication in the journal Nature Communications. Below is the foreword: Emerging additive manufacturing techniques enable investigation of the effects of pore geometry on cell behavior and function. Here, we 3D print microporous hydrogel scaffolds to test how varying pore geometry, accomplished by manipulating the advancing angle between printed layers, affects the survival of ovarian follicles. 30° and 60° scaffolds provide corners that surround follicles on multiple sides while 90° scaffolds have an open porosity that limits follicle–scaffold interaction. As the amount of scaffold interaction increases, follicle spreading is limited and survival increases. Follicle-seeded scaffolds become highly vascularized and ovarian function is fully...

What The Most Futuristic Hospitals Have That Others Don’t

Technology has certainly made great advancements in medicine, and our friends at GapMedics provide a glimpse into the most futuristic hospitals in the world. Featured on the list are: University of Missouri Health System: University Hospital in Columbia, Missouri; Hackensack University Medical Center in Hackensack, New Jersey; Wooridul Spine Hospital in Seoul, South Korea; Vale Hospital in Hensol, South Wales, United Kingdom; and Asklepios Klinik Barmbek in Hamberg, Germany. Many leading hospitals are already making profound changes and improvements that could not even have been imagined a decade ago. Science and technology working together are bringing hope and progress to patients and medical staff alike. In this infographic, we take a look at some of the most futuristic hospitals in the world, where state of the art equipment and high tech medical care is advancing healthcare across the world. What does the future of hospitals look? Some are incredibly optimistic, with hospitals developing more specialized technologies and groups to optimize their systems and to tread as many patients as possible. Even in 2015, we saw developments in prosthetics. Futurism reported that by 2030, hospitals may be a thing of the past: Predictions from the co-chair of the World Economic Forum’s Future Council, Melanie Walker, say we’ll soon enter a post-hospital world due to advances in personalized medicine, health monitoring, and nanotechnology. New and evolving technologies in medical science convince Walker we’ll live...

QUIZ: Brush Up Your Skills and Knowledge on First Aid!

Test your knowledge on how well you know first aid! You could save a life! First aid is one of the most important skills you can have. Just by performing some basic procedures or following best advice, you can save someone’s life. You may have learned some first aid at school, but is your knowledge up to date? Would you know what to do in an emergency? Yes, it can be very scary when a medical emergency happens in front of you, but if you know how to handle the situation and keep a person alive and calm until an ambulance arrives, then you could save a life or prevent more serious injuries from occurring. So many deaths and injuries can be prevented, so isn’t it worth brushing up those skills? Source:...

QUIZ: Medical Practices of the Past

How well do you know history’s important medical practices? Test your knowledge of how medical practices have evolved over time! Medical practices we use now have been reached by a wealth of knowledge gained over many years, tests and experiments and the study of data. Medicine in the 21st Century is based on scientific knowledge. So, when you realize what practices were used as little as 50 or 60 years ago, it seems amazing that we’ve come so far ever since! It also makes you thank God you weren’t alive in those times, for the treatment may have been worse than the illness. Try our quiz and see if you can guess which practices are fact and which are fiction. Source:...
