DARIEN, IL – A new study to be presented at the SLEEP 2024 annual meeting found that low-dose acetylsalicylic acid, also known as aspirin, can reduce inflammatory responses to sleep restriction. Results show that compared with placebo, preemptive administration of low-dose aspirin during sleep restriction reduced pro-inflammatory responses. Specifically, aspirin reduced interleukin-6 expression and COX-1/COX-2 double positive cells in lipopolysaccharide-stimulated monocytes, as well as C-reactive protein serum levels. “The novelty of this study is that it investigated whether we can pharmacologically reduce the inflammatory consequences of sleep restriction,” ...

A team of New York University researchers has created a new way to visualize crystals by peering inside their structures, akin to having X-ray vision. Their new technique—which they aptly named “Crystal Clear”—combines the use of transparent particles and microscopes with lasers that allow scientists to see each unit that makes up the crystal and to create dynamic three-dimensional models. “This is a powerful platform for studying crystals,” says Stefano Sacanna, professor of chemistry at NYU and the principal investigator for the study, published in the journal Nature ...

AMHERST, Mass. – A team of scientists led by François Lapointe, a research associate at the University of Massachusetts Amherst, has combined paleoclimatic data from the last 2,000 years with powerful computer modeling and in-the-field research on lake sediments and tree rings to show that an understudied phenomenon, known as atmospheric blocking, has long influenced temperature swings in the Arctic. As temperatures warm due to climate change, atmospheric blocking will help drive ever-wilder weather events. The study focused ...

Nextdoor is the world’s largest hyperlocal social media network, used by 13% of American adults. Yet little is known about the make-up of the actual neighborhoods—numbering approximately 220,000 across the United States—in which these accounts exist and what people in those communities talk about on the platform.  To address our limited understanding of this population, a team of New York University and University of Michigan researchers generated a demographic portrait of communities in which Nextdoor neighborhoods exist, the presence of public agencies in those communities, and what topics are most often discussed. Using U.S. Census data, other publicly available ...

Permafrost soils store large quantities of organic carbon and are often portrayed as a critical tipping element in the Earth system, which, once global warming has reached a certain level, suddenly and globally collapses. Yet this image of a ticking timebomb, one that remains relatively quiet until, at a certain level of warming, it goes off, is a controversial one among the research community. Based on the scientific data currently available, the image is deceptive, as an international team led by the Alfred Wegener Institute has shown in a recently released study. According to their findings, there is no single ...

San Antonio, Texas – June 3, 2024 – Recognizing an unusual prevalence of bloodstream infections (BSI) that threatened extremely ill patients receiving Extracorporeal Membrane Oxygenation, or ECMO, Tampa General Hospital (TGH) infection preventionists started an intervention that eliminated these infections completely from their 18-bed Cardiothoracic Intensive Care Unit (CTICU). At the APIC 2024 Annual Conference, presenters from the 1,000-bed, tertiary care, academic medical system  reported on how they reduced bloodstream infections in ECMO patients from a rate of 36% in October 2021 to a rate of 0% in April 2022. This rate was sustained for seven ...

The primary cause of lung cancer is smoking. However, the incidence of lung cancer among never-smokers has been steadily increasing, especially among women. While approximately 80% of never-smoking lung cancer patients are prescribed targeted therapies that focus on mutations in proteins such as EGFR and ALK, the remaining patients often receive cytotoxic chemotherapy with high side effects and relatively low response rates, highlighting the urgent need for targeted therapies. Dr. Lee Cheolju's ...

More than 90% of cervical cancer cases worldwide are caused by 9 types of high-risk HPV. The World Health Organization and the Canadian Partnership Against Cancer (CPAC) have both set targets to eliminate cervical cancer by 2040, defined as an annual rate of less than 4 per 100 000 women. The Pap test has been the primary screening ...

Berlin, Germany:  While influenza infection is a significant public health threat, causing serious illness in between three and five million people worldwide per year and leading to about up to 650,000 deaths, the effectiveness of influenza vaccines varies considerably between individuals depending on vaccine types and individual circumstances. A person’s ability to resist infection (host immunity) plays an important role in this. Now, researchers have developed a way of classifying host immunity in individuals, which may lead to the early identification of those who will not respond well to a regular vaccine schedule and therefore ...

Berlin, Germany:  Aneuploidy (the presence of an abnormal number of chromosomes) in embryos is a major cause of impaired embryo development, leading to conditions such as Down syndrome, as well as to pregnancy loss. The transfer of such embryos in women undergoing IVF is therefore usually avoided because of unfavourable pregnancy outcomes. But mosaic embryos, comprising both genetically normal and abnormal cells, can result in perfectly normal babies. Now, researchers have been able to understand how these mosaic ...

BOSTON—Among transgender and gender-diverse adults whose gender identity is nonbinary—not exclusively male or female—and who choose low-dose hormone treatment, most prefer to continue testosterone therapy at lower-than-recommended doses after at least six months of treatment, a new study finds. The study will be presented Sunday at ENDO 2024, the Endocrine Society’s annual meeting in Boston, Mass. “Current guidelines for initiation of testosterone for gender affirmation assume that transgender and gender-diverse, or trans, individuals desire both rapid and complete masculinization,” ...

BOSTON—High insulin levels contribute to worse outcomes for Black women compared to white women who have an aggressive form of breast cancer called triple-negative breast cancer, according to a study presented Sunday at ENDO 2024, the Endocrine Society’s annual meeting in Boston, Mass. Triple-negative breast cancer accounts for about 10-15% of all breast cancers. The term triple-negative breast cancer refers to the fact that the cancer cells do not have estrogen or progesterone receptors and do not make any or too much of the protein called HER2. The cells test ‘negative’ on all 3 tests. Triple-negative breast ...
