Extreme blood sugar swings in people with type 2 diabetes may increase heart disease risk

BATON ROUGE, LOUISIANA - In patients with type 2 diabetes, big swings in blood sugar levels between doctors' visits are associated with an increased risk of heart disease. The study, published in the journal Diabetes, Obesity & Metabolism, looked at more than 29,000 patients with type 2 diabetes over a two-year period. Patients who already had heart disease were excluded. The American Diabetes Association recommends adults with diabetes maintain an A1c, the average blood sugar level over the past two to three months, of less than 7 percent to reduce complications from diabetes, such ...

Sneakerheads, not hypebeasts: Defining a sneaker-driven sub-culture

Sneakers can be about style, history and even community. A new study reveals that for "Sneakerheads," sneakers are an important facet of their identities, particularly for African-American men who grew up in the 1970s and '80s coveting sneakers popularized by hip-hop stars and basketball legends. In the journal Fashion and Textiles, researchers report new insights into the motivations, brand preferences and identity considerations of Sneakerheads. The findings were drawn from interviews with 12 men in the mid-Atlantic region of the United States, many whom are African-American, and ...

Computerized adaptive screener may help identify youth at risk for suicide

Researchers have developed a computerized adaptive screener to identify youth at risk for attempting suicide. The screener, called the computerized adaptive screen for suicidal youth (CASSY), consists of 11 questions on average and correctly identified 82.4% of youth who went on to attempt suicide in the three months following screening. The results suggest this screener could serve as an easy-to-use way for providers to detect youth suicide risk in emergency department settings. The findings, funded by the National Institute of Mental Health (NIMH), ...

Standard water treatment eliminates enveloped viruses -- like the coronavirus

Among the many avenues that viruses can use to infect humans, drinking water may pose only a tiny risk for spreading certain viruses like the novel coronavirus. However, in cases where there is unauthorized wastewater disposal or other events of inadvertent mixing of wastewater with water sources, the possibility of transmission through drinking water remains unknown. Using a surrogate of the coronavirus that only infects bacteria, researchers at Texas A&M University have now presented strong evidence that existing water purification plants can easily reduce vast quantities of the virus thereby protecting our household water from such contagions. In particular, the researchers showed that the water purification step called coagulation could alone get rid of 99.999% of ...

The business of bees

The economic value of insect pollinators was $34 billion in the U.S. in 2012, much higher than previously thought, according to researchers at the University of Pittsburgh and Penn State University. The team also found that areas that are economically most reliant on insect pollinators are the same areas where pollinator habitat and forage quality are poor. "Pollinators like bees play an extremely important role in agriculture," explained senior author Vikas Khanna, Wellington C. Carl Faculty Fellow and associate professor of civil and environmental engineering at Pitt's Swanson School of Engineering. "The insects that pollinate farmers' crops underpin our ecosystem biodiversity and function, ...

Preventive anti-clotting therapy does not boost survival of critically ill COVID patients

BOSTON - Although abnormal blood clotting has been identified as one of the primary causes of death from COVID-19, early treatment in an intensive care unit (ICU) with therapeutic anticoagulation (anti-clotting) for adults who are critically ill with COVID-19 does not appear to improve chances of survival, and could do more harm than good by increasing the risk for major bleeding, a multicenter research group cautions. "In patients critically ill with COVID-19, therapeutic dose anticoagulation started early in the ICU stay was not associated with improved survival,"says Hanny Al-Samkari, MD, an investigator in the Division of Hematology/Oncology at Massachusetts General Hospital (MGH) and lead author ...

Most vulnerable often overlooked in clinical trials of new treatments for COVID-19

Studies examining the effectiveness of treatments for COVID-19 often do not include the very populations hardest hit by the disease, according to a new review by University of Chicago Medicine researchers. The findings, based on an analysis of all US COVID-19 treatment trials registered on ClinicalTrials.gov, were published Jan. 27 in the Journal of General Internal Medicine. "This study highlights the blind spot in how clinical trials are done in the United States," said senior author Neda Laiteerapong, MD, MS, a general internist and associate director of the Center for Chronic Disease Research and Policy at the University of Chicago.

Scientists discover plants' roadblock to specialty oil production

UPTON, NY - Hundreds of naturally occurring specialty fatty acids (building blocks of oils) have potential for use as raw materials for making lubricants, plastics, pharmaceuticals, and more--if they could be produced at large scale by crop plants. But attempts to put genes for making these specialty building blocks into crops have had the opposite effect: Seeds from plants with genes added to make specialty fatty acids accumulated dramatically less oil. No one knew why. Now two teams of biochemists working on separate aspects of oil synthesis at the U.S. Department of Energy's Brookhaven National Laboratory have converged to discover the mechanism behind the oil-production slowdown. As described in the journal Plant Physiology, they crossbred model plants and conducted detailed ...

Moffitt researchers discover mechanism that regulates anti-tumor activity of immune cells

TAMPA, Fla. -- The prognosis of ovarian cancer is poor, with an estimated five-year survival of only 40% for advanced disease, the stage at which most ovarian carcinomas are diagnosed. These poor outcomes are partly due to the lack of effective therapies for advanced disease and recurrence. Immunotherapies hold promise for many types of cancer; however, studies have shown that patients with ovarian cancer do not have strong responses to existing drugs. In a new article published in Nature, Moffitt Cancer Center researchers demonstrate why some ...

Minority patients miss out on cystic fibrosis drugs due to genetic test limitations

There is an impassioned debate taking place in medicine on whether race-based considerations should be a factor in research, diagnoses, or treatments. Those on one side assert that race should be ignored entirely because it is a societal construct with no biological basis, and accordingly many hospitals are abandoning long-established "race corrections" in medical algorithms and diagnostics. Others, like Meghan McGarry, MD, MS, assistant professor of pediatrics at UC San Francisco, say that we can't completely ignore race, precisely because science is rarely free of societal influence - the structural inequality ...

Discoveries at the edge of the periodic table: first ever measurements of einsteinium

Since element 99 - einsteinium - was discovered in 1952 at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) from the debris of the first hydrogen bomb, scientists have performed very few experiments with it because it is so hard to create and is exceptionally radioactive. A team of Berkeley Lab chemists has overcome these obstacles to report the first study characterizing some of its properties, opening the door to a better understanding of the remaining transuranic elements of the actinide series. Published in the journal Nature, the study, "Structural and Spectroscopic Characterization of an Einsteinium Complex," was co-led by Berkeley Lab scientist Rebecca Abergel and Los ...

The Arctic Ocean was covered by a shelf ice and filled with freshwater

The Arctic Ocean was covered by up to 900 m thick shelf ice and was filled entirely with freshwater at least twice in the last 150,000 years. This surprising finding, reported in the latest issue of the journal Nature, is the result of long-term research by scientists from the Alfred Wegener Institute and the MARUM. With a detailed analysis of the composition of marine deposits, the scientists could demonstrate that the Arctic Ocean as well as the Nordic Seas did not contain sea-salt in at least two glacial periods. Instead, these oceans were filled with large amounts of freshwater under a thick ice shield. This water could then be released into the North Atlantic in very short periods of time. Such sudden freshwater inputs could explain rapid climate oscillations for which no satisfying ...

Personalized screening to identify teens with high suicide risk

ANN ARBOR, Mich. - The suicide rate among American adolescents has rose drastically over the last decade, but many at-risk youths aren't receiving the mental health services they need. In fact, one of the greatest challenges is identifying the young people who need the most help. Now, researchers have developed a personalized system to better detect suicidal youths. The novel, universal screening tool helps caregivers reliably predict an adolescent's suicide risk - alerting them to which ones need follow-up interventions - according to Michigan Medicine-led findings published in JAMA Psychiatry. "Too many young people are dying by suicide and many at high risk go completely unrecognized and untreated," says lead author Cheryl King, Ph.D., ...

Epigenomic map reveals circuitry of 30,000 human disease regions

CAMBRIDGE, MA -- Twenty years ago this month, the first draft of the human genome was publicly released. One of the major surprises that came from that project was the revelation that only 1.5 percent of the human genome consists of protein-coding genes. Over the past two decades, it has become apparent that those noncoding stretches of DNA, originally thought to be "junk DNA," play critical roles in development and gene regulation. In a new study published today, a team of researchers from MIT has published the most comprehensive map yet of this noncoding DNA. This map provides in-depth annotation of epigenomic marks -- modifications indicating which genes are turned on or off in different types of cells -- across 833 tissues and cell types, a significant increase over ...

Two studies shed light on how, where body can add new fat cells

DALLAS - Feb. 3, 2021 - Gaining more fat cells is probably not what most people want, although that might be exactly what they need to fight off diabetes and other diseases. How and where the body can add fat cells has remained a mystery - but two new studies from UT Southwestern provide answers on the way this process works. The studies, both published online today in Cell Stem Cell, describe two different processes that affect the generation of new fat cells. One reports how fat cell creation is impacted by the level of activity in tiny organelles inside cells called mitochondria. The other outlines a process that prevents new fat cells from developing in one fat storage area in ...

Increased risk of dying from COVID for people with severe mental disorders

People with severe mental disorders have a significantly increased risk of dying from COVID-19. This has been shown in a new study from Umeå University and Karolinska Institutet in Sweden. Among the elderly, the proportion of deaths due to COVID-19 was almost fourfold for those with severe mental disorders compared to non-mentally ill people in the same age. "We see a high excess mortality due to COVID-19 among the elderly with severe mental disorders, which gives us reason to consider whether this group should be given priority for vaccines," says Martin Maripuu, associate professor at Umeå University. In the current study, the researchers studied data covering the entire Swedish population over the age of 20 during the period from 11 March to 15 June 2020. Among citizens ...

"Ghost particle" ML model permits full quantum description of the solvated electron

The behavior of the solvated electron e-aq has fundamental implications for electrochemistry, photochemistry, high-energy chemistry, as well as for biology--its nonequilibrium precursor is responsible for radiation damage to DNA--and it has understandably been the topic of experimental and theoretical investigation for more than 50 years. Though the hydrated electron appears to be simple--it is the smallest possible anion as well as the simplest reducing agent in chemistry--capturing its physics is...hard. They are short lived and generated in small quantities and so impossible to concentrate and isolate. Their structure is therefore impossible to capture with direct experimental observation such as diffraction methods or NMR. Theoretical modelling has turned out to ...

True identity of mysterious gamma-ray source revealed

An international research team including members from The University of Manchester has shown that a rapidly rotating neutron star is at the core of a celestial object now known as PSR J2039?5617 The international collaboration used novel data analysis methods and the enormous computing power of the citizen science project Einstein@Home to track down the neutron star's faint gamma-ray pulsations in data from NASA's Fermi Space Telescope. Their results show that the pulsar is in orbit with a stellar companion about a sixth of the mass of our Sun. The pulsar is slowly but surely evaporating this star. The team also found that the companion's orbit varies slightly and unpredictably over time. Using their search ...
