Diagnostic accuracy of an integrated AI tool to estimate gestational age from blind ultrasound sweeps

JAMA

2024-08-01
(Press-News.org) About The Study: Between 14 and 27 weeks’ gestation, novice users with no prior training in ultrasonography estimated gestational age as accurately with the low-cost, point-of-care artificial intelligence (AI) tool as credentialed sonographers performing standard biometry on high-specification machines. These findings have immediate implications for obstetrical care in low-resource settings, advancing the World Health Organization goal of ultrasonography estimation of gestational age for all pregnant people.

Quote from corresponding author Jeffrey S. A. Stringer, MD:

“Our study demonstrates that an AI-enabled, portable ultrasound device can estimate gestational age as accurately as an expert sonographer using an expensive, high-specification machine. This high degree of accuracy was obtained even though the users of the device had no formal training in sonography.

“The most important takeaway is the potential democratization of a critical prenatal diagnostic tool. By enabling accurate gestational age estimation without the need for expensive equipment or specialized training, this technology could significantly expand access to quality prenatal care in resource-limited settings worldwide.

“This research could transform prenatal care delivery globally. In areas where ultrasound was previously unavailable, patients can now receive timely, accurate gestational age estimates, crucial for identifying high-risk pregnancies and guiding appropriate care. Health care providers in remote or underserved areas can offer expert-level diagnostics without extensive training, potentially leading to improved maternal and neonatal outcomes on a large scale.”

Aspirin use and incidence of colorectal cancer according to lifestyle risk

2024-08-01
About The Study: Aspirin use was associated with a greater absolute reduction in risk of colorectal cancer among individuals with less healthy lifestyles in this cohort study. The findings of the study suggest that lifestyle risk factors may be useful to identify individuals who may have a more favorable risk-benefit profile for cancer prevention with aspirin.  Corresponding Authors: To contact the corresponding authors, email Andrew T. Chan, MD, MPH (achan@mgh.harvard.edu) and Long H. Nguyen, MD, MS (lnguyen24@mgh.harvard.edu).

State abortion policy and moral distress among clinicians providing abortion after the Dobbs decision

2024-08-01
About The Study: In this purposive national survey study of clinicians providing abortion, moral distress was elevated among all clinicians and more than twice as high among those practicing in states that restrict abortion compared with those in states that protect abortion. The findings suggest that structural changes addressing bans on necessary health care, such as federal protections for abortion, are needed at institutional, state, and federal policy levels to combat widespread moral distress.  Corresponding Author: To contact the corresponding author, ...

Universal background checks, permit requirements, and firearm homicide rates

2024-08-01
About The Study: This cross-sectional study found that universal background checks alone were not associated with firearm homicide rates, but a permit requirement for the purchase and possession of firearms was associated with substantially reduced rates of firearm homicide. The findings suggest that combining universal background checks and permit-to-purchase requirements is an effective strategy for firearm-related fatality reduction.  Corresponding Author: To contact the corresponding author, Michael Siegel, MD, MPH, email mike.siegel@tufts.edu.

Study examines effect of fish oil in older adults’ brains

2024-08-01
A clinical trial at Oregon Health & Science University suggests that a subset of older adults with a genetic predisposition to Alzheimer’s disease may benefit from fish oil supplements. The study published today in the journal JAMA Network Open. The results come amid claims that fish oil supplements can improve brain function in people with memory problems. The study found no statistically significant benefit for all older adults in general. However, among those enrolled in the study who also carry a gene associated with Alzheimer’s disease, it showed a reduction in the breakdown of nerve cells in the brain. The study’s senior co-author from OHSU ...

Conformational dynamics and allostery elucidate how GPCR couple to multiple G-proteins, offering mechanistic insights into coupling-promiscuity and novel drug discovery strategies
2024-08-01
In a groundbreaking study, a multinational research team led by Dr. Adnan Sljoka (RIKEN) and Prof. Akio Kitao (Tokyo Tech), in collaboration with Prof. Scott Prosser (University of Toronto), has carried out experimental and computational studies to elucidate the mechanisms behind G protein selectivity and efficacy in the human adenosine A2A receptor (A2AR). A2AR is a member of major drug targets G protein-coupled receptor (GPCR) superfamily, which engages the G protein and initiates cell signaling, influencing heart health, inflammation, cancer, and brain diseases. Scientists have ...

Proteins as the key to precision medicine: Finding unknown effects of existing drugs

Proteins as the key to precision medicine: Finding unknown effects of existing drugs
2024-08-01
Fewer side effects, improved chances of healing: the goal of precision medicine is to provide patients with the most individualized treatment possible. This requires a precise understanding of what is happening at the cellular level. For the first time, researchers at the Technical University of Munich (TUM) have now succeeded in mapping the interactions of 144 active substances with around 8,000 proteins. The results could help to identify previously unknown potential benefits of existing drugs. Practically all drugs either affect, produce or eliminate proteins – or are, in fact, proteins. But what exactly happens when a high or low dose is taken? And what is going ...

Cheese of the future: Consumers open to animal-free alternatives

2024-08-01
Companies and institutes are currently working on biotechnological processes for the production of dairy products without the use of cows: In so-called precision fermentation, egg and milk proteins are produced with the help of bacteria, yeasts or other fungi. This results in foods such as milk or cheese with a familiar flavour and texture. Supporters hope that this will lead to more sustainable food production, as nutrient-rich proteins can be produced using fewer resources. But will consumers accept such products? Researchers at the University of Göttingen have found that a large proportion of German consumers are willing to try and buy cheese produced in this way. ...

New Moffitt study explores how antifragility could revolutionize cancer treatment

2024-08-01
TAMPA, Fla. — Researchers constantly seek innovative approaches to tackle cancer. One concept gaining traction is antifragility, a property where systems not only withstand stress but improve because of it. In cancer research, this concept is particularly relevant for tumors that adapt and evolve in response to treatment. Understanding antifragility could lead to more effective therapies. In a new study published in npj Complexity, Moffitt Cancer Center researchers offer a new perspective on antifragility, proposing ...

Advances in 3D organ bioprinting: A step towards personalized medicine and solving organ shortages

Advances in 3D organ bioprinting: A step towards personalized medicine and solving organ shortages
2024-08-01
In a latest review published in Engineering, an international team of scientists from China and the United States has presented a comprehensive analysis of the latest advancements in 3D organ bioprinting. This innovative technology holds the potential to revolutionize regenerative medicine and tackle some of the most pressing issues in organ transplantation. Organ damage or failure, whether resulting from injury, disease, or aging, poses a significant challenge due to the body’s limited natural regenerative capabilities. Traditional organ transplantation, while lifesaving, is fraught with difficulties including donor shortages and the risk of immune rejection. This has spurred a ...
