The human cornea possesses a remarkable preservation period of approximately 14 days after death, making it a viable option for transplantation. By donating healthy corneas to those suffering from corneal diseases, which are major contributors to vision loss, patients have the potential to regain their sight and experience improved vision.

Despite corneal diseases affecting 57 million people worldwide and resulting in $410 billion in productivity losses and reduced quality of life, only a small fraction of individuals are eligible for corneal transplantation. To address this issue, researchers at the University of Ottawa in Canada have made a significant breakthrough by developing a new material that can reshape and thicken damaged corneal tissue, promoting healing and recovery.

Researchers at the University of Sheffield have developed a groundbreaking robotics technology called medical telexistence (MediTel), which has the potential to provide remote medical treatment to casualties in hazardous emergency environments. Led by the Advanced Manufacturing Research Center (AMRC), Sheffield Robotics, and the Department of Automatic Control and Systems Engineering, the team successfully created a mobile, robotic-controlled uncrewed ground vehicle (UGV) equipped with virtual reality (VR) capabilities.

In a remarkable nine-month development period, the fully integrated MediTel solution features two robotic arms that can remotely operate medical tools to conduct a critical initial assessment of a casualty within 20 minutes. This includes vital checks such as temperature, blood pressure, and heart rate, as well as performing a palpation of the abdomen and administering pain relief through an auto-injector. Real-time data is continuously streamed to the remote operator during the assessment.

Exciting new research, to be presented at the Society of Interventional Radiology Annual Scientific Meeting in Boston, reveals a groundbreaking technique called interventional cryoneurolysis, capable of regenerating damaged nerves using a frozen needle under advanced imaging guidance. This cutting-edge method offers hope to patients suffering from persistent pain following traumatic injuries and may provide a non-opioid alternative for pain management.

Conducted by researchers at Emory University, the study focused on treating eight patients with chronic nerve pain resulting from prior traumas. CT-guided interventional cryoneurolysis employs imaging to precisely place a needle and freeze the damaged nerves, leading them to degenerate and lose function. The remarkable part of the process is the potential for regeneration—if the nerve is exposed to the right amount of cold over the correct area and time, it can be replaced with a healthy nerve.

Researchers at The University of Texas Health Science Center at San Antonio have developed a groundbreaking artificial intelligence (AI) tool capable of accurately counting brain lesions on MRI scans within seconds. This innovative tool is expected to play a vital role in helping neuroradiologists assess patients’ brain diseases at earlier stages.

Led by researcher Mohamad Habes, PhD, from the Glenn Biggs Institute for Alzheimer’s and Neurodegenerative Diseases, the team demonstrated the AI tool’s effectiveness in identifying and counting enlarged perivascular spaces (ePVS’s). These spaces, filled with cerebrospinal fluid, surround arteries and veins and serve as a marker for cerebral small-vessel disease, which can lead to stroke and dementia. The study involved a follow-up analysis of 1,026 individuals who participated in the Multi-Ethnic Study of Atherosclerosis (MESA).
