Published How biological aging clocks tick (via sciencedaily.com) Original source
Aging clocks can measure the biological age of humans with high precision. Biological age can be influenced by environmental factors such as smoking or diet, thus deviating from the chronological age that is calculated using the date of birth. The precision of these aging clocks suggests that the aging process follows a program. Scientists have now discovered that aging clocks actually measure the increase in stochastic changes in cells.
Published 'Digital afterlife': Call for safeguards to prevent unwanted 'hauntings' by AI chatbots of dead loved ones (via sciencedaily.com) Original source
Researchers lay out the need for design safety protocols that prevent the emerging 'digital afterlife industry' causing social and psychological harm.
Published Neuropathy very common, underdiagnosed (via sciencedaily.com) Original source
Neuropathy, the nerve damage that causes pain and numbness in the feet and hands and can eventually lead to falls, infection and even amputation, is very common and underdiagnosed, according to a new study.
Published 'Wraparound' implants represent new approach to treating spinal cord injuries (via sciencedaily.com) Original source
A tiny, flexible electronic device that wraps around the spinal cord could represent a new approach to the treatment of spinal injuries, which can cause profound disability and paralysis. A team of engineers, neuroscientists and surgeons developed the devices and used them to record the nerve signals going back and forth between the brain and the spinal cord. Unlike current approaches, the new devices can record 360-degree information, giving a complete picture of spinal cord activity.
Published Exercise, new drug class recommended for management of hypertrophic cardiomyopathy (via sciencedaily.com) Original source
Experts released a new clinical guideline for effectively managing individuals diagnosed with hypertrophic cardiomyopathy (HCM). The guideline reiterates the importance of collaborative decision-making with patients who have HCM and provides updated recommendations for the most effective treatment pathways for adult and pediatric patients.
Published Teens who view their homes as more chaotic than their siblings have poorer mental health in adulthood (via sciencedaily.com) Original source
Adolescents who view their households as more unstructured, disorganized, or hectic than their siblings develop more mental health and behavioral problems in early adulthood, according to new research.
Published New guidelines for depression care emphasize patient-centred approach (via sciencedaily.com) Original source
Psychiatrists and mental health professionals have a new standard for managing major depression, thanks to refreshed clinical guidelines.
Published Children sleep problems associated with psychosis in young adults (via sciencedaily.com) Original source
Children who experience chronic lack of sleep from infancy may be at increased risk of developing psychosis in early adulthood, new research shows.
Published Damaging impact of heat waves on vital organs (via sciencedaily.com) Original source
Researchers have found evidence of the molecular causes of the damaging impact heat stress causes on the gut, liver and brain in the elderly. These findings point to the potential of developing precise prognostic and therapeutic interventions.
Published Faster approach for starting extended-release naltrexone to treat opioid use disorder shown effective (via sciencedaily.com) Original source
Starting people with opioid use disorder on extended-release, injectable naltrexone (XR-naltrexone) within five to seven days of seeking treatment is more effective than the standard treatment method of starting within 10-15 days, but requires closer medical supervision, according to results from a clinical trial. The findings suggest that this rapid treatment protocol could make XR-naltrexone more viable as a treatment option for opioid use disorder, which continues to take lives at an alarming rate.
Published More than 321,000 U.S. children lost a parent to drug overdose from 2011 to 2021 (via sciencedaily.com) Original source
An estimated 321,566 children in the United States lost a parent to drug overdose from 2011 to 2021, according to a new study. The rate of children who experienced this loss more than doubled during this period, from approximately 27 to 63 children per 100,000. The highest number of affected children were those with non-Hispanic white parents, but communities of color and tribal communities were disproportionately affected.
Published Childhood maltreatment responsible for up to 40 percent of mental health conditions (via sciencedaily.com) Original source
A study has found the widespread impact of child abuse and neglect, with analysis suggesting they cause nearly half of common mental conditions. Researchers say childhood maltreatment should be treated as a public health priority.
Published How psychedelic drugs interact with serotonin receptors to potentially produce therapeutic benefits (via sciencedaily.com) Original source
Researchers have shed valuable light on the complex mechanisms by which a class of psychedelic drugs binds to and activates serotonin receptors to produce potential therapeutic effects in patients with neuropsychiatric disorders such as depression and anxiety.
Published Pressure to be 'perfect' causing burnout for parents, mental health concerns for their children (via sciencedaily.com) Original source
Is the status of 'perfect parent' attainable? Researchers leading a national dialogue about parental burnout say 'no,' and a new study finds that pressure to try to be 'perfect' leads to unhealthy impacts on both parents and their children.
Published Gene linked to learning difficulties has direct impact on learning and memory (via sciencedaily.com) Original source
A gene previously linked to intellectual disability has been found to regulate learning and memory in mice.
Published 'Mathematical microscope' reveals novel, energy-efficient mechanism of working memory that works even during sleep (via sciencedaily.com) Original source
Researchers have discovered a mechanism that creates memories while reducing metabolic cost, even during sleep. This efficient memory occurs in a part of the brain that is crucial for learning and memory, and where Alzheimer's disease begins.
Published THC lingers in breastmilk with no clear peak point (via sciencedaily.com) Original source
When breastfeeding mothers in a recent study used cannabis, its psychoactive component THC showed up in the milk they produced. The research also found that, unlike alcohol, when THC was detected in milk there was no consistent time when its concentration peaked and started to decline. Importantly, the researchers discovered that the amount of THC they detected in milk was low -- they estimated that infants received an average of 0.07 mg of THC per day. For comparison, a common low-dose edible contains 2 mg of THC. The research team stressed that it is unknown whether this amount has any impact on the infant.
Published Could getting enough sleep help prevent osteoporosis? (via sciencedaily.com) Original source
In people's early- to mid-20s, they reach what is called peak bone mineral density, which is higher for men than it is for women, according to researchers. This peak is one of the main determinants of fracture risk later in life. After reaching this peak, a person's bone density remains roughly stable for a couple of decades. Then, when women enter the menopausal transition, they experience accelerated bone loss. Men also experience bone density decline as they age. Sleep patterns also evolve over time.
Published Emergency department packed to the gills? Someday, AI may help (via sciencedaily.com) Original source
Emergency departments nationwide are overcrowded and overtaxed, but a new study suggests artificial intelligence (AI) could one day help prioritize which patients need treatment most urgently.
Published Biomarker found to help identify cells that can repair damaged blood vessels (via sciencedaily.com) Original source
Researchers have discovered a protein marker to help identify cells able to repopulate in patients with damaged blood vessels. Their findings could lead to new therapies for people with endothelial dysfunction, a type of disorder that contributes to coronary artery disease that may occlude with plaque and lack ability to carry sufficient blood into the heart tissue causing a heart attack.
