2025-02-03

(Press-News.org) About The Study: Using passive sensing on a sample of U.S. adolescents, this study found half of adolescents use their smartphones during school for at least 66 minutes daily, primarily using messaging and social media. These findings extend a prior study limited to Android devices that found adolescents spent a median of 43 minutes on their phones during school.

Alarming rise in rates of advanced prostate cancer in California

2025-02-03

Alarming Rise in Rates of Advanced Prostate Cancer in California Following a change in screening guidelines, the incidence went up across the state, even more than it has nationally. The incidence of advanced prostate cancer in California rose markedly in the decade since doctors stopped routinely screening all men for the disease, according to a new study by UC San Francisco. After declining for many years, the death rate from the disease also plateaued in most regions across the state. The findings reinforce the need for screening that can identify potentially fatal tumors without raising false alarms about ones that pose no threat to the patient. The ...

Nearly half of adults mistakenly think benefits of daily aspirin outweigh risks

2025-02-03

For years, healthy older adults were advised by doctors to take a low-dose aspirin daily as a way to reduce the risk of heart attack. But in March 2019, the American College of Cardiology and the American Heart Association (AHA) announced new guidelines and no longer routinely recommended a daily dose of aspirin for healthy adults over the age of 70 because the risk of gastrointestinal bleeding outweighs the benefits. Nearly five years later, many Americans still have not received the message. The Annenberg Public Policy Center (APPC) of the University of Pennsylvania finds in a new health survey that nearly half (48%) of U.S. ...

Cardiovascular disease medications underused globally

2025-02-03

Secondary prevention medications for cardiovascular diseases (CVD) are underused globally and additional strategies to increase their use are needed to improve CVD management and reduce premature mortality rates, according to study published today in JACC, the flagship journal of the American College of Cardiology. The study observed participants with CVD from 17 countries over 12 years and found that medication use remains low with little improvement. Secondary prevention of CVD focuses on preventing further health problems in people already diagnosed with CVD. This includes managing risk factors through lifestyle changes, medications and ...

Amazon Pharmacy's RxPass program improves medication adherence, helps prime members save money, study finds

2025-02-03

Approximately half of all Americans do not take their medication as prescribed by their doctor. This medication non-adherence causes an estimated 125,000 additional deaths and as much as $300 billion a year in additional medical appointments, emergency department visits, and hospitalizations. A new study published in the Journal of the American Medical Association (JAMA) Network Open finds Amazon Pharmacy’s subscription service for common medications, RxPass, leads to significant improvements in medication adherence while reducing out-of-pocket costs for patients. This first-of-its-kind study evaluated the potential of subscription models to support prescription medication access ...

Tufts University School of Medicine, ATI Physical Therapy launch first-of-its-kind collaboration to make physical therapy education and career advancement more accessible and affordable

2025-02-03

With demand for physical therapy services projected to increase 27 percent by 2030, Tufts University School of Medicine (TUSM) and ATI Physical Therapy (ATI), a leading provider of physical therapy services across the United States, are launching a joint initiative aimed at expanding the physical therapist workforce and making the Doctor of Physical Therapy (DPT) Programs at TUSM more accessible. As part of the first-of-its-kind collaboration, TUSM and ATI will contribute scholarships each semester for up to 45 ATI employees in TUSM’s DPT programs each academic year. The accelerated ...

Could lycopene—a plant extract—be an effective antidepressant?

2025-02-03

Emerging evidence suggests that lycopene—a natural plant extract—may have antidepressant properties. New research in Food Science & Nutrition reveals the mechanisms behind its antidepressant effects. In mice with depressive-like behaviors, brain analyses revealed impairments in the hippocampus. Lycopene treatment lessened these impairments and reversed the animals’ depressive-like traits. Lycopene treatment boosted the expression of brain-derived neurotrophic factor (BDNF), a protein with roles in many aspects of brain function. Experiments indicated that a signaling pathway involving BDNF (called the BDNF-TrkB pathway, ...

Study shows urine test for prostate cancer could be used at home

2025-02-03

Researchers at Vanderbilt and the University of Michigan have shown that a simple at-home urine test for prostate cancer screening is highly accurate. The exciting new results, published in The Journal of Urology, build upon a prior Vanderbilt study of prostate cancer screening that required a digital rectal exam. The results are important because this could enable at-home testing and increased access to testing for patients undergoing telehealth care or living in remote areas. Traditional prostate cancer screening with PSA testing and biopsy has been shown to lead to unnecessary procedures and overdiagnosis of low-grade cancers, according to ...

Shaping future of displays: clay/europium-based technology offers dual-mode versatility

2025-02-03

The world of display technology is on the cusp of a transformative breakthrough, with electrochemical stimuli-responsive materials gaining more attraction. Based on external stimuli, such as low voltage, these materials can instantaneously undergo electrochemical reactions. These electrochemical reactions can result in the production of different colors, revolutionizing the age of display solutions. An electrochemical system consists of electrodes and electrolytes. Combining the luminescent and coloration molecules on the electrodes instead of the electrolyte can offer higher efficiencies and stability for display devices. To this end, a research team ...

Optimizing ADHD treatment: revealing key components of cognitive–behavioral therapy

2025-02-03

Attention-deficit hyperactivity disorder (ADHD) is a well-known neurodevelopmental disorder that affects the brain's ability to regulate attention and control impulses. It poses many challenges to those affected, typically making it difficult for them to sustain focus, follow through with instructions, and maintain a calm and restful state. As one of the most common neurodevelopmental disorders, ADHD impacts individuals throughout their lives, creating a breadth of social, emotional, academic, and workplace challenges. Despite its high ...

Breaking barriers in thioxanthone synthesis: a double aryne insertion strategy

2025-02-03

Thioxanthones are fascinating organic compounds that have found their way into many industrial and everyday applications. In the printing industry, for example, they help inks dry faster when exposed to light thanks to their light-absorption properties, making the printing process quicker and more efficient. Some thioxanthones have been developed into FDA-approved drugs used to treat parasitic infections and cancer. Additionally, their effectiveness as photocatalysts has led some researchers to explore their potential as stabilizers against electrical breakdown. Thioxanthones have also been ...
