(Press-News.org) FINDINGS
A new study shows that an artificial intelligence (AI) model co-developed by researchers in the UCLA Jonsson Comprehensive Cancer Center and department of Urology at UCLA can help doctors determine the extent of cancer within the prostate.
In a series of tests, the AI model was found to be more accurate at predicting tumor margins than magnetic resonance imaging (MRI), potentially improving the effectiveness of focal therapy, standardizing treatment margin definition, and reducing the chance of cancer recurrence.
BACKGROUND
Focal therapy, a minimally invasive treatment approach used for localized tumors, is an alternative treatment for patients with intermediate-risk prostate cancer. The technique involves imaging guidance, such as MRI, to accurately locate the tumor and guide the treatment. Real-time imaging during the procedure helps monitor the treatment progress and ensures the precise delivery of energy to the intended area.
Current methods, however, can underestimate the extent of prostate cancer, complicating the definition of focal treatment margins. AI has the potential to better define these margins than MRI alone, a crucial factor in ensuring accurate diagnosis, precise treatment planning, and effective surgical procedures.
METHOD
Working with scientists at Avenda Health, the team used biopsy data from multiple institutions to train the AI model, called Unfold-AI, to define margins during focal therapy. Testing was then conducted in an independent dataset of 50 patients who had radical prostatectomy for intermediate-risk cancer at the Stanford University School of Medicine. The team found the AI model was more accurate and effective at predicting tumor margins than conventional methods.
IMPACT
The advancement is an outgrowth of research initiated in 2009 by Dr. Leonard Marks, professor and deKernion Endowed Chair in Urology at the David Geffen School of Medicine at UCLA. The software has the potential to help surgeons predict extension into the capsule of the prostate, help radiation therapists boost energy delivery to most important spots, and improve the results of focal ablation of prostate cancer.
Unfold-AI, which is being commercialized by Avenda Health, was spotlighted by NBC News along with President Biden’s AI Summit earlier this month.
JOURNAL
The study was published in the journal European Urology Open Science.

Bariatric surgery cuts risk for major cardiac events and death in patients with obesity and sleep apnea
2023-06-27
LAS VEGAS – June 27, 2023 – Bariatric surgery, also called weight-loss or metabolic surgery, was associated with a 42% lower risk of major adverse cardiovascular events (MACE), including heart failure, heart attack, stroke, and atrial fibrillation in patients with moderate to severe obstructive sleep apnea (OSA), according to a new study from Cleveland Clinic and presented here today at the American Society for Metabolic and Bariatric Surgery (ASMBS) 2023 Annual Scientific Meeting. Researchers also report metabolic surgery ...
New study finds fewer heart attacks, strokes and death among patients with diabetes and history of metabolic surgery
2023-06-27
LAS VEGAS – June 27, 2023 – Patients with diabetes and a history of metabolic surgery had significantly fewer heart attacks, strokes, hospitalizations and death compared to matched patients who did not have the surgery, according to a new study* presented here today at the American Society for Metabolic and Bariatric Surgery (ASMBS) 2023 Annual Scientific Meeting.
Patients reduced their chances of winding up in a hospital with a heart attack by more than 35%, a stroke by more than 25% and congestive heart failure by nearly ...
Bariatric surgery guidelines lowered BMI threshold for eligibility, but relatively few heeded the call
2023-06-27
LAS VEGAS – June, 27, 2023 – Patient eligibility for bariatric surgery, also called weight-loss or metabolic surgery, has expanded over the last decade and its safety and effectiveness even further established in clinical studies and professional guidelines, but relatively few patients with a body mass index (BMI) below 35 actually get the surgery in any given year, according to new studies presented here at the American Society for Metabolic and Bariatric Surgery (ASMBS) 2023 Annual Scientific Meeting.
In one study*, University of Southern California (USC) researchers found only 3.5% of the more than one million bariatric ...

More women are using single embryos during fertility treatment
2023-06-27
Copenhagen, Denmark: More women are having just one embryo transferred per cycle of fertility treatment to get pregnant, according to research presented at the 39th annual meeting of the European Society of Human Reproduction and Embryology (ESHRE) [1].
Preliminary data from the ESHRE European IVF-monitoring Consortium (EIM) [2] shows that nearly three in five (57.6%) out of all in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI) procedures in 2020 in Europe involved the transfer ...
Algorithm finds sperm in infertile men faster and more accurately than doctors
2023-06-27
Copenhagen, Denmark: A new artificial intelligence (AI) tool can identify sperm in severely infertile men in seconds compared to the hours it takes scientists, according to results presented today (Tuesday) at the 39th annual meeting of the European Society of Human Reproduction and Embryology (ESHRE) [1].
The study authors say the algorithm they have developed brings hope to men who want a biological child but have no sperm in their semen.
Currently, these patients must undergo a procedure where a portion of their testes is removed to help them become fathers. Embryologists extract sperm manually from this biopsy sample to fertilise the partner’s eggs ...
Lupus flare-ups strongly linked to specific bacterial growth in gut
2023-06-27
Recurrent bouts of systemic lupus erythematosus, marked by the body’s immune system attack of its own tissues, closely tracked with measureable upticks in growth in the gut of a certain species of bacteria.
New research from NYU Grossman School of Medicine shows that bacterial blooms of the gut bacterium Ruminococcus blautia gnavus occurred at the same time as disease flare-ups in five of 16 women with lupus of diverse racial backgrounds studied over a four-year period. Systemic lupus erythematosus involves damaging inflammation, especially in the kidneys, but also in joints, skin, and blood vessels. ...
