A study found that children exposed to maternal gestational diabetes and low socioeconomic status have a higher risk of developing childhood ADHD. The risk is doubled when both factors are present, suggesting a significant environmental contribution to the development of the disorder.
The American College of Physicians has released the sixth edition of its Ethics Manual, addressing new topics such as health catastrophes and social media professionalism. Researchers also found that spinal manipulation therapy (SMT) and home exercise are more effective than medication for relieving neck pain. In contrast, in-hospital ...
Research suggests that cerebrospinal fluid biomarkers can identify individuals at high risk for Alzheimer's disease up to 5-10 years before symptoms appear. Studies found reduced Aβ42 and elevated T-tau and P-tau levels in patients with mild cognitive impairment who later developed Alzheimer's.
A new study has discovered well-preserved fossil insect ears from 50 million year-old crickets and katydids, shedding light on the evolution of insect hearing. The findings suggest that these insects evolved their supersensitive hearing long before bat predators came to be.
Researchers discovered that increased production of microRNA miR-21 stimulates progressive muscle deterioration in a mouse model of Duchenne muscular dystrophy. Inhibiting miR-21 reduced collagen levels and prevented fibrogenesis in diseased animals, suggesting it as a potential therapeutic target.
A systematic review of studies suggests that physical activity is positively related to improved academic performance in children. The findings support the idea that exercise may help cognition by increasing blood flow to the brain, reducing stress, and improving mood.
A Baylor University study reveals that humility is a positive quality with potential benefits, predicting greater helpfulness in aiding someone in need. Researchers found that humble individuals offered more time to help compared to less humble ones, especially when personal or situational factors were controlled.
Researchers found that quantitative CT scans can identify patients with greater airway wall thickness and emphysema, who are at higher risk for frequent exacerbations. These findings could lead to individualized, targeted management of COPD disease.
Researchers from Cornell University created a healthier cigarette filter with lycopene and grape seed extract, drastically reducing toxic free radicals. The study demonstrates the potential for an alternative type of cigarette filter with a free radical scavenging additive.
A study found that marijuana ingredients Δ9-THC and CBD affect different regions of the brain during visual processing tasks. Δ9-THC increased psychotic symptoms by modulating prefrontal and striatal function, while CBD enhanced response to salient stimuli.
The American College of Physicians has released the sixth edition of its Ethics Manual, covering topics such as culturally sensitive care, social media professionalism, and research ethics. The manual provides guidance for clinicians, educators, and researchers on navigating complex ethical dilemmas in medical practice.
Researchers found a potential new risk factor for dementia and Alzheimer's disease in women, linking the hormone adiponectin to an increased risk. Elevated levels of adiponectin were associated with an increased risk of all-cause dementia and AD in women, contrary to its expected anti-inflammatory properties.
Adolescents diagnosed with schizophrenia show greater decreases in gray matter volume and increases in cerebrospinal fluid in the frontal lobe compared to healthy peers. Progressive brain changes are also linked to poorer prognosis, including longer hospitalization and reduced symptom improvement.
A new study published in Archives of General Psychiatry found that deep brain stimulation is a safe and effective intervention for treatment-resistant depression in patients with unipolar and bipolar disorders. After four weeks of single-blind stimulation, 58% of patients achieved remission and showed significant improvement in function.
The hepatitis C virus has evolved a unique relationship with the liver's miR-122 microRNA to stabilize its RNA and promote efficient replication. A new experimental antiviral drug works by binding to and sequestering this microRNA, destabilizing viral genome and accelerating degradation.
A study found that maternal gestational diabetes and low socioeconomic status significantly increase the risk of attention deficit hyperactivity disorder (ADHD) in six year olds. The risk doubles with either factor alone, but increases exponentially when both are present.
A nationwide study found demographic and clinical factors associated with Parkinson's disease survival. Dementia was diagnosed in 69.6% of the study population, particularly among black patients, and significantly increased mortality risk. Environmental exposures also seemed to influence survival rates.
