Prevalence of obesity with and without confirmation of excess adiposity among US adults

JAMA

2025-04-17

(Press-News.org) About The Study: Among U.S. adults ages 20 to 59, the prevalence of obesity by body mass index (BMI) only was nearly identical with the obesity prevalence after confirmation of excess adiposity. Approximately 98% of individuals identified as having obesity based on BMI had excess adiposity.

Population attributable fraction of incident dementia associated with hearing loss

2025-04-17

About The Study: The results of this cohort study suggest that treating hearing loss might delay dementia for a large number of older adults. Public health interventions targeting clinically significant audiometric hearing loss might have broad benefits for dementia prevention. Future research quantifying population attributable fractions should carefully consider which measures are used to define hearing loss, as self-reporting may underestimate hearing-associated dementia risk.

New study reveals how cleft lip and cleft palate can arise

2025-04-17

CAMBRIDGE, MA -- Cleft lip and cleft palate are among the most common birth defects, occurring in about one in 1,050 births in the United States. These defects, which appear when the tissues that form the lip or the roof of the mouth do not join completely, are believed to be caused by a mix of genetic and environmental factors. In a new study, MIT biologists have discovered how a genetic variant often found in people with these facial malformations leads to the development of cleft lip and cleft palate. Their findings suggest that the variant diminishes cells’ supply of transfer RNA, a molecule ...

Scientists hack cell entry to supercharge cancer drugs

2025-04-17

A new discovery could pave the way for more effective cancer treatment by helping certain drugs work better inside the body. Scientists at Duke University School of Medicine, University of Texas Health Science Center at San Antonio, and University of Arkansas have found a way to improve the uptake of a promising class of cancer-fighting drugs called PROTACs, which have struggled to enter cells due to their large size. The new method works by taking advantage of a protein called CD36 that helps pull substances into cells. By designing drugs to use this CD36 pathway, researchers delivered 7.7 to 22.3 times more of the drug inside cancer cells, making ...

Study: Experimental bird flu vaccine excels in animal models

2025-04-17

BUFFALO, N.Y. — A vaccine under development at the University at Buffalo has demonstrated complete protection in mice against a deadly variant of the virus that causes bird flu. The work, detailed in a study published today (April 17) in the journal Cell Biomaterials, focuses on the H5N1 variant known as 2.3.4.4b, which has caused widespread outbreaks in wild birds and poultry, in addition to infecting dairy cattle, domesticated cats, sea lions and other mammals. In the study, scientists describe a process they’ve developed for creating doses with precise ...

Real-world study finds hydroxyurea effective long-term in children living with sickle cell disease

2025-04-17

(WASHINGTON, April 17, 2024) — Hydroxyurea remains effective long-term in reducing emergency department visits and hospital days for children living with sickle cell disease (SCD), according to new research published in Blood Advances. “This is one of the first large, real-world, long-term studies to assess the efficacy of hydroxyurea outside of a controlled setting,” said study author Paul George, MD, a pediatric hematology/oncology fellow and PhD candidate at Emory University School of Medicine and Aflac Cancer and Blood Disorders Center at Children’s ...

FAU designated a National Center of Academic Excellence in Cyber Research

2025-04-17

Florida Atlantic University has been recognized as a National Center of Academic Excellence in Cyber Research (CAE-R) by the National Security Agency (NSA) and its partners in the National Centers of Academic Excellence in Cybersecurity (NCAE-C). This prestigious designation, awarded through the academic year 2030, affirms the university’s leadership and innovation in the field of cybersecurity research at the doctoral level. This recognition places FAU among an elite group of institutions nationwide that have demonstrated a sustained commitment to cutting-edge research in cyber defense and security. The CAE-R designation is awarded to universities whose programs meet rigorous ...

European potato genome decoded: Small gene pool with large differences

2025-04-17

A research team has decoded the genome of historic potato cultivars and used this resource to develop an efficient method for analysis of hundreds of additional potato genomes. Potatoes are a staple food for over 1.3 billion people. But despite their importance for global food security, breeding successes have been modest. Some of the most popular potato cultivars were bred many decades ago. The reason for this limited success is the complex genome of the potato: there are four copies of the genome in each cell instead of just two. ...

Nontraditional risk factors shed light on unexplained strokes in adults younger than 50

2025-04-17

Research Highlights: Among adults ages 18-49 (median age of 41 years) who were born with a hole in the upper chambers of their heart known as patent foramen ovale (PFO), strokes of unknown cause were more strongly associated with nontraditional risk factors, such as migraines, liver disease or cancer, rather than more typical factors such as high blood pressure. Migraine with aura was the top factor linked to strokes of unknown causes, also called cryptogenic strokes, especially among women. Embargoed ...

Extreme drought contributed to barbarian invasion of late Roman Britain, tree-ring study reveals

2025-04-17

Three consecutive years of drought contributed to the ‘Barbarian Conspiracy’, a pivotal moment in the history of Roman Britain, a new Cambridge-led study reveals. Researchers argue that Picts, Scotti and Saxons took advantage of famine and societal breakdown caused by an extreme period of drought to inflict crushing blows on weakened Roman defences in 367 CE. While Rome eventually restored order, some historians argue that the province never fully recovered. The ‘Barbarian Conspiracy’ of 367 CE was one of the most severe threats to Rome’s hold on Britain since the Boudiccan revolt three centuries earlier. Contemporary sources indicate that components ...

Antibiotic-resistant E. albertii on the rise in Bangladeshi chicken shops

2025-04-17

If you have ever chickened out of eating chicken, your unease may not have been unreasonable. Osaka Metropolitan University researchers have detected alarming rates of Escherichia albertii, an emerging foodborne pathogen, in retail chicken meat in Bangladesh. Their findings show extensive contamination and significant antimicrobial resistance, underscoring the potential risks to public health. E. albertii is a less known but probably not less dangerous relative of E. coli. First described in Bangladesh in 2003, this bacterium ...
