New Surgical Glue Could Render Stitches And Sutures Obsolete

When wounds are quickly and securely closed following injury, healing is faster, risks of infection are minimized, and more serious sustained injury can be prevented. A new type of surgical glue has been created to do that in a fast-acting and reliable manner. It may even change first aid and medical response procedures at car accidents, in combat zones, and at emergency sites.

Fast Forming For Better Wound Healing

MeTro behaves like a silicone sealant, much like those used to create a water seal in bathrooms and other household applications, but it works even faster. Once administered to human tissue, MeTro rapidly forms to gel-like thickness and serves to seal a wound. This action occurs as highly elastic proteins and light sensitive molecules are set after being exposed to UV light. The gel takes just 60 seconds to thicken and solidify, which is vital to blocking out bacteria in urgent situations.

Modifiable For Recovery Times

While MeTro securely remains in contact with the tissue to which it’s applied, it retains some elasticity so it moves with the patient and prevents wounds from reopening. The treatment can also be modified with a degrading enzyme that determines how soon MeTro will begin to breakdown. Whether sealing is required for minutes or months, the gel can be catered to appropriate recovery times.

For Use On Difficult To Treat Sites

Northeastern University and Australia’s University of Sydney Researchers responsible for creating MeTro have also shown how it can be used on treatment sites that are otherwise difficult to seal due to exposure to bodily fluids and natural expansion and contraction. The substance shows potential for use on vital areas that are challenging to stitch, suture, or bandage, such as internal organs like the lungs and heart.


As MeTro has been tested successfully on pigs, researchers are now focusing on trials in humans. Will their development render conventional wound healing and closing treatments obsolete? Comment and share your thoughts.

3D Printing Will Bring Big Medical Advances

The word revolutionary is not too strong for describing how 3D printing, also known as additive manufacturing, will advance health care. The technology is expected to enable the printing of organs and tissues based on recipients’ cells and increase customization of medical tools and devices.

3D Printed Organs

Organ transplant recipients must control tissue rejection with lifelong medication regimens. Additionally, the acquisition of suitable organs requires long waits. Additive manufacturing using materials generated from a recipient’s cells solves these problems. The base cell material creates a genetic match that eliminates tissue rejection. The ability to make an organ also removes waiting for a suitable donor.

An experiment at the Wake Forest Institute for Regenerative Medicine has proven the viability of organ printing. A printer made the tissue for a new bladder from a patient’s blood cells. The medical scientists have also replicated heart valves and livers.

Prosthetic Manufacturing

People in need of prosthetics often have long wait times for custom-fitted pieces. With 3D printing, prosthetics manufacturing can become widely distributed, which speeds their availability at the point of care. Costs could be reduced as well.

Customized Surgical Assistive Devices

From dental drill guides to inhalers, 3D printing allows for clinicians to make custom devices quickly. Sometimes only a single day is needed to fabricate a customized piece because 3D printing cuts prototype development time by 80 to 90 percent.

Medical Supply Production

Demand for long cotton swabs for collecting samples for coronavirus tests has exploded due to the pandemic. The medical startup company OPT Industries had met demand with 3D printed swabs that also collect and release fluids better than their cotton counterparts. The company’s 3D printers produce swabs that are actually woven lattices of extremely thin fibers. With swab production now at 80,000 swabs a day, the company has helped to ease swab supply shortages. Automated swab printing also allows the company to produce the swabs at a competitive price.

In what ways do you think 3D printing could improve patient care and outcomes?

ABOUT Wake Forest Institute for Regenerative Medicine

The Wake Forest Institute for Regenerative Medicine (WFIRM) is recognized as an international leader in translating scientific discovery into clinical therapies. Physicians and scientists at WFIRM were the first in the world to engineer laboratory-grown organs that were successfully implanted into humans. Today, this interdisciplinary team that numbers about 400 is working to engineer more than 40 different replacement tissues and organs, and to develop healing cell therapies – all with the goal to cure, rather than merely treat, disease.

A number of the basic principles of tissue engineering and regenerative medicine were first developed at the institute. WFIRM researchers have successfully engineered replacement tissues and organs in all four categories – flat structures, tubular tissues, hollow organs and solid organs – and 15 different applications of cell/tissue therapy technologies, such as skin, urethras, cartilage, bladders, muscle, kidney, and vaginal organs, have been successfully used in human patients.

The institute, which is part of Wake Forest School of Medicine, is located in the Innovation Quarter in downtown Winston-Salem, NC.

Explosive Growth Expected For AI-Enabled Medical Imaging Diagnostics

Artificial intelligence has proven its usefulness for accurately interpreting medical scans. The systems can analyze medical images in minute detail, draw upon vast quantities of diagnostic data, and supplement the work of human pathologists. Because these capabilities will revolutionize diagnostics, IDTechEX predicts that the global market for AI medical imaging diagnostics will expand by 10,000 percent by 2040.

Breast Cancer Diagnostics

Clinicians rely on medical imaging to detect and treat breast cancer. An AI developed by Google called LYNA has shown 99 percent accuracy in finding metastatic breast cancer tumors. Another breakthrough has emerged from researchers in Berlin, Germany, and Oslo, Norway. Their tissue-section analysis system uses AI to examine images pixel by pixel. To help pathologists check the images, the AI highlights the exact areas within the image used to reach a diagnosis.

Remote Patient Monitoring Improves Care For Chronically Sick

Clinicians typically only see patients for a few minutes. They must make decisions based on the brief snapshot of patient vitals measured at the time of interaction. Technology that enables remote patient monitoring (RPM) places much information in the hands of clinicians. Devices that collect patient data either in hospital beds or at home, provide medical workers with a big picture of what is happening with people’s bodies. When monitoring people from their homes, clinicians gain the opportunity to provide preventative care that greatly reduces doctor visits and hospitalizations.

Integration With Wearable Tech

RPM devices work by applying a wearable device to patients that then transmits data to clinicians by the internet. For example, the portability of the Philips Medical Tablet allows clinicians to manage more patients. The tablet only needs a wi-fi connection to send information to a central monitoring system where clinicians can attend to emerging problems remotely.

Similarly, the Dozee Pro device that has recently completed clinical trials in India helps clinicians follow patients in-home care settings. The device alerts medical workers to harmful changes in heart function, respiratory rate, and blood pressure so that they can take quick action before a problem becomes a medical crisis.

Medicare Supports RPM

In the United States, Medicare has approved payments for users of RPM. The advantages of RPM have become clear for serving an elderly population managing chronic conditions, like heart disease and diabetes. Clinicians, who had the ability to catch alarming changes in patient vitals early, were able to reduce patients’ emergency room visits by 92 percent. Readmission rates to hospitals fell by 40 percent when RPM was used post-discharge.
