“Osteo-cardiovascular” patients at highest risk for falls and death, Chinese study finds

(Press-News.org)
A new study by researchers at Peking University and the Chinese PLA General Hospital has found that multimorbidity—living with multiple chronic diseases—is closely associated with worsening fall conditions and mortality among middle-aged and older adults in China. The findings, published in Health Data Science, identify a distinct group at especially high risk: individuals with both cardiovascular and musculoskeletal conditions, dubbed the “osteo-cardiovascular fallers.”
Falls are a major cause of injury and death in older populations globally, particularly in low- and middle-income countries like China. While previous research linked chronic illnesses with increased fall risk, this study is one of the first to show how different patterns of multimorbidity affect transitions between fall states—ranging from no falls to mild, severe falls, and even death—over time.
Analyzing data from 14,244 individuals aged 45 and older from the China Health and Retirement Longitudinal Study (CHARLS), the researchers used advanced statistical models to trace how health conditions influenced nearly 11,000 transitions between fall states over a seven-year period. They identified four main multimorbidity patterns: osteo-cardiovascular, pulmonary-digestive-rheumatic, metabolic-cardiovascular, and neuropsychiatric-sensory. Among them, the osteo-cardiovascular group had the highest risk of transitioning from no falls to severe falls or death, and the lowest likelihood of recovering from a previous fall.
“Multimorbidity, especially the osteo-cardiovascular pattern, significantly worsens the likelihood of a fall or death and reduces the chance of improvement,” said lead author Mingzhi Yu, a doctoral student at the School of Public Health, Peking University. “These findings provide clear guidance for targeted clinical interventions and preventive strategies.”
The study further showed that individuals with this pattern faced a 2.09 times higher risk of death and a 1.67 times higher risk of severe falls compared to healthy participants. Moreover, their chances of recovery—such as improving from severe to mild falls—were significantly lower than others.
“Our work highlights the need for integrated care approaches tailored to patients with overlapping bone and heart diseases,” said co-author Dr. Lihai Zhang, Chief Physician at the Chinese PLA General Hospital. “Addressing both systems simultaneously may prevent long-term deterioration.”
The research team plans to build on these insights by identifying additional fall-related risk factors and developing practical fall prevention strategies for high-risk groups.

Without clear and effective biological tests for autism based on genes, brain or blood measurements, diagnosis today still largely depends on clinical assessment. The standard way of doing this is by observing how the individual fits the criteria for autism listed in gold standard manuals like the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5).
These criteria are divided into two categories: one for restricted or repetitive behaviours, actions, or activities, and another for differences in social communication and interaction. In the end, however, it is the clinician, relying on years of ...

People with autism are typically diagnosed by clinical observation and assessment. To deconstruct the clinical decision process, which is often subjective and difficult to describe, researchers used a large language model (LLM) to synthesize the behaviors and observations that are most indicative of an autism diagnosis. Their results, publishing in the Cell Press journal Cell, show that repetitive behaviors, special interests, and perception-based behaviors are most associated with an autism diagnosis. These findings have potential to improve diagnostic guidelines ...

In diagnosing autism – the developmental variant that affects around 80 million people worldwide – medical practitioners today put too much emphasis on a child's lack of sociability and not enough on their interests and how they naturally behave spontaneously with objects.
And so, to be more accurate in their assessments, health authorities should start tapping the vast analytic powers of artificial intelligence, combined with the experience of clinicians, and come up with better diagnostic criteria.
That's ...

About The Study: In this cohort study of 3.7 million individuals, living alone with depression or anxiety was associated with an increased risk of suicide, particularly among middle-aged individuals and men. These findings underscore the importance of preventing mental illness, such as depression and anxiety, while addressing living arrangements as a critical factor in suicide risk assessments for individuals with these conditions.

About The Study: In this survey study of older U.S. adults, most participants agreed that Medicare should cover weight management medications and more than half of those with body mass index (BMI) of 30 or greater were interested in using them. These results should inform decisions to include weight management medications in the Medicare and commercial insurance programs, as well as utilization policies to control health care costs.

When someone has a stroke, it can accelerate the loss of cognitive ability over the coming years.
Stroke survivors who have attended some level of higher education may face even steeper mental declines, according to a study led by Michigan Medicine.
In an analysis of cognitive outcomes for more than 2,000 patients seen for stroke between 1971 and 2019, college graduates performed better on initial post-stroke examinations of global cognition, a measure of overall cognitive ability that includes mental functions like memory, attention and processing speed.
However, ...

Los Angeles (February –, 2025)—Evolving roughly 27 different times in the long history of fish, bioluminescence—the biological production of light—is one of the flashier survival tools used for luring prey, communication, and recognizing potential mates among various species. In a new study published in Ichthyological Research, an international team of researchers studied the organs that produce light in Vinciguerria mabahiss, a rare species of fish from the Red Sea. This paper marks the first-ever close examination of these organs, providing key information on their structure ...

Getting zapped with millions of volts of electricity may not sound like a healthy activity, but for some trees, it is. A new study, published in New Phytologist, reports that some tropical tree species are not only able to tolerate lightning strikes, but benefit from them. The trees may have even evolved to act as lightning rods.
The research was led by Evan Gora, a forest ecologist at Cary Institute of Ecosystem Studies. Gora studies how lightning impacts biodiversity and carbon storage in Panama’s tropical forests.
Lightning kills hundreds of millions of trees per year. But in 2015, while working in Panama, Gora and his colleagues came across ...
