Depression linked with higher risk of long-term physical health conditions

Adults with depression accrue physical illnesses in midlife and older age faster than those without

Depression linked with higher risk of long-term physical health conditions
2025-02-13
(Press-News.org) Adults with a history of depression gain long-term physical conditions around 30% faster than those without, according to research publishing February 13th in the open-access journal PLOS Medicine. Kelly Fleetwood of the University of Edinburgh, United Kingdom, and colleagues argue that their study suggests depression should be viewed as a ‘whole body’ condition, and integrated approaches should be used to manage mental and physical health.

Depression is the most common mental health condition and is associated with a range of adverse physical health outcomes such as heart disease and diabetes. Past research has compared people with and without depression to see how many physical conditions they develop over time, but most studies look at a small number of illnesses. Fleetwood and colleagues aimed to quantify the association between depression and the rate at which conditions accrued in midlife and older age.

The team included 172,556 volunteers in the UK Biobank study, aged 40-71 years, who completed a baseline assessment between 2006 and 2010. They selected 69 physical conditions and followed participants for an average of 6.9 years. Initially, those with depression had an average of three physical conditions compared with an average of two in those without. Over the study period, adults with a history of depression accrued an average of 0.2 additional physical conditions per year, while those without accrued 0.16. The most common new conditions were osteoarthritis (15.7% of those with depression at baseline vs 12.5% without), hypertension (12.9% vs 12.0%) and gastroesophageal reflux disease (13.8% vs 9.6%).

The results highlight that previous diagnosis of depression is a marker of risk for development of long-term physical health conditions during middle and older-age. Most healthcare systems are designed to treat individual conditions rather than individuals with multiple conditions, and the authors believe that integrated approaches to managing both mental and physical health could improve care and outcomes.

The authors add, “People who’ve experienced depression are more likely to develop long-term physical health conditions such as heart disease and diabetes; however, existing healthcare systems are designed to treat individual conditions, instead of individual people with multiple conditions. We need healthcare services to take an integrated approach to caring for people who have both depression and long-term physical health conditions.”

Los Angeles groundwater remained depleted after 2023 deluge, study finds

2025-02-13
The greater Los Angeles area has long been subject of intense seismographic monitoring. A network of highly sensitive seismometers peppers the region on a constant vigil for earthquakes. Now researchers at the Stanford Doerr School of Sustainability have developed a new way to use that existing infrastructure and its decades of data to estimate water levels in the region’s aquifers, which serve some 10 million residents of Los Angeles and Orange counties.  The researchers analyzed the ...

With the help of powerful technologies and the intrepidness to get close ...

Dessert stomach emerges in the brain

2025-02-13
To find the cause of the "dessert stomach", the researchers investigated the reaction of mice to sugar and found that completely satiated mice still ate desserts. Investigations of the brain showed that a group of nerve cells, the so-called POMC neurones, are responsible for this. These neurones become active as soon as the mice were given access to sugar which facilitated their appetite. When mice are full and eat sugar, these nerve cells not only release signaling molecues that stimulate satiety, but also one of the body's own opiate: ß-endorphin. This acts on other nerve cells with opiate receptors and triggers a feeling of reward, ...

Fungus ‘hacks’ natural immune system causing neurodegeneration in fruit flies

2025-02-13
A fungal infection has been shown to trigger a fruit fly’s own immune system to destroy brain cells leading to signs of neurodegeneration, a new study has found.   The paper published in PLOS Biology today found that a fungus called Beauveria bassiana was able to make the fly’s innate immune system trigger a process that kills neurons and glia in the brain, leading to more than half of flies dying after seven days compared to half of control samples living for nearly 50 days.   In experiments conducted by a team of academics from the University of ...

A new view on 300 million years of brain evolution

2025-02-13
Leuven, 14 February 2025 – In a new study published in Science, a Belgian research team explores how genetic switches controlling gene activity define brain cell types across species. They trained deep learning models on human, mouse, and chicken brain data and found that while some cell types are highly conserved between birds and mammals after millions of years of evolution, others have evolved differently. The findings not only shed new light on brain evolution; they also provide powerful tools for studying how gene regulation shapes different cell types, across species or different disease states. Our brain, and by extension ...

Birds have developed complex brains independently from mammals

Birds have developed complex brains independently from mammals
2025-02-13
The pallium is the brain region where the neocortex forms in mammals, the part responsible for cognitive and complex functions that most distinguishes humans from other species. The pallium has traditionally been considered a comparable structure among mammals, birds, and reptiles, varying only in complexity levels. It was assumed that this region housed similar neuronal types, with equivalent circuits for sensory and cognitive processing. Previous studies had identified the presence of shared excitatory and inhibitory neurons, as well as general connectivity patterns suggesting a similar evolutionary path in these ...

Protected habitats aren’t enough to save endangered mammals, MSU researchers find

2025-02-13
Images EAST LANSING, Mich. – Tropical forests are massive biodiversity storehouses. While these rich swathes of land constitute less than one-tenth of Earth’s surface, they harbor more than 60% of known species. Among them is a higher concentration of endangered species than anywhere else on Earth.  However, these regions are also under immense pressure, as tropical land is rapidly being transformed for industrial and agricultural purposes.   Worldwide, regional governments and international groups are establishing new protected areas to slow further loss of threatened species. However, new research appearing in the journal PLOS Biology demonstrates ...

Scientists find new biomarker that predicts cancer aggressiveness

Scientists find new biomarker that predicts cancer aggressiveness
2025-02-13
HOUSTON ― Using a new technology and computational method, researchers from Fred Hutch Cancer Center and The University of Texas MD Anderson Cancer Center have uncovered a biomarker capable of accurately predicting outcomes in meningioma brain tumors and breast cancers. In the study, published today in Science, the researchers discovered that the amount of a specific enzyme, RNA Polymerase II (RNAPII), found on histone genes was associated with tumor aggressiveness and recurrence. Hyper-elevated levels of RNAPII on these histone genes indicate cancer over-proliferation and potentially contribute to chromosomal changes. These findings point to the use of a new genomic technology as ...

UC Irvine astronomers gauge livability of exoplanets orbiting white dwarf stars

2025-02-13
Irvine, Calif., Feb. 13, 2025 — Among the roughly 10 billion white dwarf stars in the Milky Way galaxy, a greater number than previously expected could provide a stellar environment hospitable to life-supporting exoplanets, according to astronomers at the University of California, Irvine. In a paper published recently in The Astrophysical Journal, a research team led by Aomawa Shields, UC Irvine associate professor of physics and astronomy, share the results of a study comparing the climates of exoplanets at two different stars. One is a hypothetical white dwarf that’s passed through much of its life cycle and is on a slow path ...
