During Breast Cancer Awareness Month, Cedars-Sinai Cancer experts are available to discuss an uptick in breast cancer among younger patients and the innovative ways the academic medical center is treating breast cancer in diverse Southern California communities and beyond.

IU School of Medicine expands point-of-care ultrasound training

Indiana University School of Medicine is expanding its training program for point-of-care ultrasound (POCUS) by investing in portable ultrasound systems for all students, residents, and fellows across seven specialties to use in curricula and patient care at the academic health center in Indianapolis.

A ‘FAAIRI’s touch to ease children’s fear of needles

Vaccinations, blood tests, or IVs – it’s fair to say that no child likes a needle. So, when it comes to the jab, a light touch and a caring approach is incredibly welcomed – both by the child and the parent. Now, world-first research from the University of South Australia shows that while many children suffer distress, new ultrasound-guided techniques could provide much-needed reprieve.

FAMU-FSU College of Engineering dean will lead U.S. Army study that uses ultrasound to examine burn wounds

Suvranu De, dean of the FAMU-FSU College of Engineering, is leading a five-year, $1.3 million cooperative research agreement with the U.S. Army that will use ultrasound and artificial intelligence to investigate the characteristics and healing trajectory of burn wounds, leading to faster diagnosis and improved recovery.

NIH funds study of ultrasound with genetics to treat brain disorders

Researchers have developed methods to study and manipulate areas of the brain, though many of those methods are restricted by the limited depth that light can reach within the brain. A multidisciplinary team at Washington University in St. Louis plans to overcome that limitation by integrating ultrasound with genetics to precisely modify neurons in the brain.

A New Strategy to Break Through Bacterial Barriers in Chronic Treatment-Resistant Wounds

Researchers in UNC’s School of Medicine’s department of Microbiology and Immunology and the UNC-NC State Joint Department of Biomedical Engineering have developed a new strategy to improve drug-delivery into chronic wounds infections.

Microbubble Macrophages Track Tumors #ASA184

At the 184th ASA Meeting, Ashley Alva of the Georgia Institute of Technology will describe how attaching microbubbles to macrophages, a type of white blood cell, can create high-resolution and sensitive tracking images useful for disease diagnosis. Because of the attached microbubbles, the cells sent back an echo when hit with ultrasound, which is nonionizing and noninvasive and has great depth of penetration. This allowed the team to visualize the macrophages in vivo with high resolution and sensitivity. Visualizing macrophages in vivo could also provide a powerful tool for understanding immune responses and monitoring therapeutic efficacy.

Combined ultrasound technique can reposition and break up urinary stones in awake patients

A new technique combining two types of focused ultrasound waves offers a promising approach for treatment of urinary stones located in the ureter, according to a feasibility study in The Journal of Urology®, an Official Journal of the American Urological Association (AUA). The journal is published in the Lippincott portfolio by Wolters Kluwer.

Ultrasound Could Save Racehorses from Bucked Shins

When racehorses enter training at about 2 years old, they can develop tiny stress fractures and new bone formations in their legs. This condition, called bucked shin, occurs in about 70% of the animals. In The Journal of the Acoustical Society of America, researchers have developed a method to screen for bucked shin using ultrasound. Axial transmission, in which an ultrasound emitter and receiver are placed on the skin to induce and measure wave velocities, is frequently used to study osteoporosis in humans. The method could detect bucked shin more easily and preserve the health and growth of young horses.

Increased Precision and Safety in Spinal Tap with PASS – An Ultrasound-Guided Lumbar Puncture Procedure

PASS (Point-Assisted Spinal Sonography), an ultrasound-guided lumbar puncture device from Chula doctors and engineers, helps increase the precision and confidence in spinal tap procedures while reducing risks and pain for patients.

Blacks Found Twice as Likely to Have Atherosclerosis as Hispanics in Young Adult Populations in Underserved Communities

A unique Mount Sinai study focused on a multi-ethnic, underserved community in New York City shows that young Black adults are twice as likely to have atherosclerosis as similarly situated young Hispanic adults.

Ultrasound-Assisted Laser Technique Vaporizes Artery Plaque #ASA182

Atherosclerosis, a buildup of plaque, can lead to heart disease, artery disease, and chronic kidney disease and is traditionally treated by inserting and inflating a balloon to expand the artery. During the 182nd ASA Meeting, Rohit Singh, of the University of Kansas, will present a method that combines a low-power laser with ultrasound to remove arterial plaque safely and efficiently.

Ultrasound remotely triggers immune cells to attack tumors in mice without toxic side effects

A new cancer immunotherapy pairs ultrasound with specially engineered CAR T cells to destroy malignant tumors while sparing normal tissue. The new experimental therapy significantly slowed down the growth of solid cancerous tumors in mice.

Tiny, Wireless, Injectable Chips Use Ultrasound to Monitor Body Processes

Researchers at Columbia Engineering report that they have built what they say is the world’s smallest single-chip system, consuming a total volume of less than 0.1 mm3. The system is as small as a dust mite and visible only under a microscope. In order to achieve this, the team used ultrasound to both power and communicate with the device wirelessly

Breaching the Blood-Brain Barrier to Deliver Precious Payloads

RNA-based drugs may change the standard of care for many diseases, making personalized medicine a reality. So far these cost-effective, easy-to-manufacture drugs haven’t been very useful in treating brain tumors and other brain disease. But a team of researchers at Georgia Tech and Emory University has shown that a combination of ultrasound and RNA-loaded nanoparticles can temporarily open the protective blood-brain barrier, allowing the delivery of potent medicine to brain tumors.

‘Leap forward’ in risk management of rectal cancer

Rectal cancer, along with colon cancer, is the third-most common type of cancer in the United States, and treatment and surgery greatly affect the quality of life of patients. A multi-disciplinary team at Washington University in St. Louis has developed and tested an innovative imaging technique that is able to differentiate between rectal tissues with residual cancers and those without tumors after chemotherapy and radiation, which could one day help to avoid unnecessary surgeries in some patients who have achieved complete tumor destruction after chemoradiation.

Singing a Tumor Test Song

Singing may be the next-generation, noninvasive approach to determining the health of a patient’s thyroid. When a person sings, the vibrations create waves in the tissue near the vocal tract called shear waves. If a tumor is present in the thyroid, the elasticity of its surrounding tissue increases, stiffening, and causing the shear waves to accelerate. Using ultrasound imaging to measure these waves, researchers can determine the elasticity of the thyroid tissue. They demonstrate the technique in Applied Physics Letters.

Lung Ultrasounds Could Help Determine COVID-19 Outcome

Researchers have developed a method using ultrasound imaging to score a patient’s lung health, which may help predict if a patient with COVID-19 will worsen. Using 14 points in the lungs, they looked for abnormalities and assigned each spot a score out of 3 based on its severity. Adding up all the points, the researchers found the total lung ultrasound score was higher for those who had a worsening outcome of COVID-19. Umberto Sabatini’s presentation will be a part of the 179th ASA Meeting of the Acoustical Society of America.
