Gene mutation discovered that causes language impairment, ADHD and myasthenia
Two studies have revealed that certain disorders of the CAPRIN1 gene have significant consequences for people. First, the research team showed that insufficient production of the protein CAPRIN1 in the brain can lead to developmental differences, including autism spectrum disorders, attention deficit hyperactivity disorder (ADHD), and language disorders. Furthermore, the scientists identified a specific mutation […]
Why Has This Young Man Lost the Ability to Squat and Clench His Fists?
Why has this 31-year-old man gradually developed significant stiffness in his joints, which is now preventing him from clenching his fists or squatting? That’s what Yafang Zhou, MD, PhD, of Xiangya Hospital in Hunan, China, and colleagues wanted to figure out. As they reported in JAMA Neurology, the man’s experience began about 6 months previously, […]
Intravitreal Methotrexate Reduces Reoperation After Retinal Detachment Repair
NEW YORK CITY — Postoperative intravitreal methotrexate for retinal detachment led to a significant reduction in reoperation and improved visual acuity, a retrospective chart review showed. The absolute difference in reoperation rate was small, greater than 1% without methotrexate versus 0.4% with three to five postoperative injections of the antiproliferative agent, but the difference translated […]
Link Between Neovascular Eye Disease, CVD Tracked to Retinal Lesions
NEW YORK CITY — Subretinal drusenoid deposits (SDD) had a significant association with underlying cardiovascular disease (CVD), adding a missing link between age-related macular degeneration (AMD) and CVD, a prospective study showed. Among 47 patients with CVD and AMD, 40 (85%) had SDD with or without subretinal drusen. An analysis aided by artificial intelligence showed […]
A better diet helps beat depression in young men
Young men with a poor diet saw a significant improvement in their symptoms of depression when they switched to a healthy Mediterranean diet, a new study shows. Depression is a common mental health condition that affects approximately 1 million Australians each year. It is a significant risk factor for suicide, the leading cause of death […]
Another Link Between Prostate Cancer Hormone Tx and Impaired Cognition
Hormonal therapy for advanced prostate cancer, particularly enzalutamide (Xtandi), had a significant association with cognitive impairment, an analysis of a large drug-safety database showed. Traditional hormonal therapy increased the odds of cognitive impairment by 47% versus men who did not receive the therapy. The odds more than doubled among men who received novel androgen receptor […]
Urgent action required to protect world’s coral reefs from disappearing within three decades, warn experts
An international team of environmental scientists have published a series of significant recommendations to protect, conserve and study the world’s coral reefs — the ‘canaries in the coal mine’ of climate change. The Vibrant Oceans Initiative presented their white paper on the future of the delicate and crucial habitats at the Our Oceans Conference held […]
Dramatic, Durable Hair Growth With Oral JAK Inhibitor
BOSTON — An oral Janus kinase (JAK) inhibitor produced significant, durable hair growth, including scalp, eyebrows, and eyelashes in patients with severe alopecia areata, according to long-term data from two randomized trials. Almost 40% of patients achieved a Severity of Alopecia Tool (SALT) score ≤20 (total percentage of hair loss) at 52 weeks with a […]
Study questions the role of vitamin D2 in human health but its sibling, vitamin D3, could be important for fighting infections
New research has found significant differences between the two types of vitamin D, with vitamin D2 having a questionable impact on human health. However, the study found that vitamin D3 could balance people’s immune systems and help strengthen defences against viral infections such as Covid-19. In a collaborative study by the Universities of Surrey and […]
Dog feces and urine could be harming nature reserves, according to new study
New research finds that dogs being walked in nature reserves contribute a significant amount of nutrients to the environment through their faeces and urine, which researchers warn could negatively impact local biodiversity. The research is published in the British Ecological Society journal, Ecological Solutions and Evidence. Significant levels of fertilisation Researchers at Ghent University have […]
