Additional GP funding has been squeezed this year, finds BMJ investigation

Budgetary decisions by commissioners across England are affecting GPs’ ability to offer their patients what most people regard as essential services and forcing some practices to close, an investigation by The BMJ has found. This year, eight in 10 Integrated Care Boards (ICBs) - responsible for planning health services for their local population - either reduced or froze discretionary funding for general practices as a proportion of their overall budget for services such as taking blood, wound care, ...

AI could predict breast cancer risk via ‘zombie cells’

Women worldwide could see better treatment with new AI technology which enables better detection of damaged cells and more precisely predict the risk of getting breast cancer, shows new research from the University of Copenhagen. Breast cancer is one of the most common types of cancer. In 2022, the disease caused 670,000 deaths worldwide. Now, a new study from the University of Copenhagen shows that AI can help women with improved treatment by scanning for irregular-looking cells to give better risk assessment. The study, published in The Lancet Digital Health, found that the AI technology was far better at predicting risk of cancer ...

Are branch faults the “on-ramps” that lead to great continental transform earthquakes?

The five largest continental transform earthquakes since 2000 all originated on a branch of the main fault—and two researchers predict that the next great earthquake of this type will also get its start on a branch or splay fault. Last year’s magnitude 7.8 Pazarcık earthquake in Türkiye was one of these large and damaging earthquakes, where two continental tectonic plates slide past each other horizontally. That earthquake began on a branch fault, as did the 2001 magnitude 7.8 Kokoxili earthquake in northern Tibet, the 2002 magnitude 7.9 Denali earthquake in Alaska, the 2008 magnitude 7.9 Wenchuan earthquake in China, and the 2016 ...

When a child hurts, validating their pain may be the best first aid

Whether it’s a sore arm or a fear of injections, how a child is treated when they present with pain could significantly affect how they respond to and manage pain later in life.   In a new study from the University of South Australia, researchers say that parents and doctors should be mindful of how they talk to and treat children experiencing pain – no matter how big or small the injury – knowing that these foundational experiences can be carried forward into adulthood.   Drawing from diverse research across developmental psychology, child mental health, and pain sciences, researchers say that it may be important to validate children’s pain by ...

Mars’ missing atmosphere could be hiding in plain sight

Mars wasn’t always the cold desert we see today. There’s increasing evidence that water once flowed on the Red Planet’s surface, billions of years ago. And if there was water, there must also have been a thick atmosphere to keep that water from freezing. But sometime around 3.5 billion years ago, the water dried up, and the air, once heavy with carbon dioxide, dramatically thinned, leaving only the wisp of an atmosphere that clings to the planet today.  Where exactly did Mars’ ...

Hardest hit by heat

Each passing year, climate change drives summer temperatures to new extremes, with heat records being shattered one after another. In a new study, scientists from the Max Planck Institute for Demographic Research (MPIDR) have examined how extreme temperatures in the US affect the mortality of people from different racial groups. Risto Conte Keivabu, Ugofilippo Basellini, and Emilio Zagheni (director of MPIDR) analyzed data from 1993 to 2005 and examined racial differences in temperature-related deaths. The study found that both extreme cold (temperatures in the coldest 5%) and extreme heat (temperatures in the hottest 5%) increase mortality rates, with heat disproportionate impacting ...

Pigs may be transmission route of rat hepatitis E to humans

COLUMBUS, Ohio – New research suggests that pigs may function as a transmission vehicle for a strain of the hepatitis E virus (HEV) common in rats that has recently been found to infect humans. The Rocahepevirus ratti strain is called “rat HEV” because rats are the primary reservoir of the virus. Since the first human case was reported in a person with a suppressed immune system in Hong Kong in 2018, at least 20 total human cases have been reported – including in people with normal immune function. People infected with rat HEV did not report exposure to rats, leaving the cause of infection undefined. ...

Effects of transjugular intrahepatic portosystemic shunt on renal and pulmonary function in hepatic decompensation with and without hepatorenal and hepatopulmonary syndromes

Effects of transjugular intrahepatic portosystemic shunt on renal and pulmonary function in hepatic decompensation with and without hepatorenal and hepatopulmonary syndromes

Cirrhosis is one of the leading causes of mortality from non-communicable diseases, with complications arising as liver function deteriorates. HRS and HPS represent the most severe outcomes of cirrhosis, associated with systemic vasodilation driven by elevated levels of vasodilators like nitric oxide (NO). These complications significantly impair renal and pulmonary functions, leading to high mortality rates. TIPS, by shunting blood from the portal to systemic circulation, can potentially improve renal function by increasing systemic blood volume. However, the diversion of NO through TIPS could exacerbate systemic hypotension, posing a risk to renal ...

Encoding human experience: Study reveals how brain cells compute the flow of time

A landmark study led by UCLA Health has begun to unravel one of the fundamental mysteries in neuroscience – how the human brain encodes and makes sense of the flow of time and experiences. The study, published in the journal Nature, directly recorded the activity of individual neurons in humans and found specific types of brain cells fired in a way that mostly mirrored the order and structure of a person’s experience. They found the brain retains these unique firing patterns after the experience is concluded and can rapidly replay them while at rest. Furthermore, the brain is also able to utilize these learned patterns to ready itself for future stimuli following that experience. ...

New study: Deep-sea discovery shines light on life in the twilight zone

TAMPA, Fla. (Sept. 23, 2024) – The ocean’s twilight zone is deep, dark, and — according to new research — iron deficient. No sunlight reaches this region 200 to 1,000 meters below the sea surface, where levels of iron, a key micronutrient, are so low that the growth of bacteria is restricted. To compensate, these bacteria produce molecules called siderophores, which help the bacteria scavenge trace amounts of iron from the surrounding seawater. The paper detailing these unexpected findings from the Pacific Ocean will publish on Wednesday, Sept. 25, at 11 a.m. ET (4 p.m. London Time) in Nature, and will be viewable at that time at this link. The ...

Brazilian fossils reveal jaw-dropping discovery in mammal evolution

These fossils, belonging to the mammal-precursor species Brasilodon quadrangularis and Riograndia guaibensis, offer critical insights into the development of the mammalian jaw and middle ear, revealing evolutionary experiments that occurred millions of years earlier than previously thought. Mammals stand out among vertebrates for their distinct jaw structure and the presence of three middle ear bones. This transition from earlier vertebrates, which had a single middle ear bone, has long fascinated scientists. The new study explores how mammal ancestors, known as cynodonts, evolved these features ...

Now we know why children with Down’s syndrome have higher risk of Leukemia

People with Down’s syndrome face a higher risk of developing Leukemia. Now researchers from the University of Copenhagen and Stanford University explain why, by identifying specific changes in blood cells of people with Down’s syndrome. In the world, one out of 700 children are born with Down’s syndrome. A syndrome, where the child has an extra copy of chromosome 21, resulting in 47 chromosomes instead of 46. This typically results in characteristic physical features and some level of learning disability. But newborns with Downs syndrome also tend to have an elevated number of red blood ...
