People around the world are living longer than ever before, but are spending many of those extra years in poor health, according to a new Global Burden of Disease (GBD) study published today. lancet public health. The researchers found that global incidence disparities widened in nearly every country and region analyzed between 1990 and 2023. Globally, the proportion of lifetimes spent in poor health increased, but trends varied by country, with a decline in this proportion in a minority of countries. Within one generation, the global incidence gap widened by nearly two years, increasing from 8.8 years in 1990 to…

Caffeine is the most widely used stimulant and psychoactive substance in the world, and coffee is where most people consume caffeine. Most adults can safely consume up to 400 mg of caffeine per day (or up to five 8-ounce cups of caffeinated coffee per day), according to a new scientific statement from the American Heart Association. For some people, moderate coffee consumption may also be associated with a lower risk of cardiovascular disease. The situation changes as the dose increases. Energy drinks that contain concentrated sources of caffeine, especially energy shots, can increase your risk of cardiovascular problems. The study…

Female rats exposed prenatally to the main psychoactive compound in cannabis have an increased vulnerability to binge drinking during early adolescence. Male rats that receive exactly the same prenatal exposure initially avoid alcohol, but their drinking habits eventually escalate over time. A small study published in the Journal of Psychopharmacology outlines how fetal drug exposure biologically alters brain pathways that govern reward and behavior. The brain relies on an internal network of chemical signals called the endocannabinoid system. These naturally produced chemicals tightly control how early fetal brain cells grow, move, and connect. The naturally occurring chemical shares a similar…

A child’s socio-economic environment shares measurable relationships with physical brain structure and cognitive test scores. A large-scale study of elementary school students found that biological sex fundamentally changes these relationships, while socially constructed categories such as race do not. The findings suggest that unequal access to resources is the true cause of most observed racial differences in brain development. This study Developmental cognitive neuroscience. A child’s socio-economic status includes more than just household income. This includes a variety of environmental factors such as parental education, food security, neighborhood safety, and the emotional environment at home. Researchers know that children from…

Wistar scientists have developed a new type of bispecific T-cell engager (BTE) that is effective against ovarian cancer in preclinical studies. This is a major advance for this type of immunotherapy, which has been used successfully against blood cancers, but has so far been less effective against solid tumors. Researchers have developed a new “knob-in-to-hole” platform for delivering BTE. This manipulates the antibody’s “knob” to force it to match the antibody’s “hole”, resulting in a perfect locking of the two puzzle pieces for a precise fit. They showed that DNA-based technology can be used to deliver BTE. This is a…

An Australian study is the first to show that a swimming program is clinically effective in reducing disability caused by chronic low back pain. today, British Journal of Sports Medicinethe EduSwim clinical trial found that an eight-week individualized program that combined swimming and education under the guidance of a physical therapist improved function and pain in people with lower back pain to a greater extent than education alone. Swimming is commonly recommended as an exercise for people with chronic back pain, but there has been a complete lack of evidence as to whether it actually helps. We undertook this study…

Repeated weight gain and loss can not only derail diets but also accelerate muscle loss in middle-aged people, a new University of California, San Francisco study finds, as weight-loss drugs revolutionize obesity treatment. In a study published on July 21, Radiologyresearchers found that even though both groups finished the study with about the same total body weight as they started, those whose weight fluctuated repeatedly lost significantly more thigh muscle over four years than those whose weight remained relatively stable. “When people’s weight changed cyclically, they lost a lot of muscle along with fat, and the muscle never came back,”…

The Pulmonary Embolism Reporting and Data System (PE-RADSTM) framework for diagnosing and classifying acute pulmonary embolism using CT and magnetic resonance (MR) angiography was announced today. RadiologyJournal of the Radiological Society of North America (RSNA). Developed by the American College of Radiology (ACR) in collaboration with representatives from six other major medical groups, PE-RADS aims to streamline communication and patient care for potentially life-threatening diseases. Timely and accurate assessment of acute pulmonary embolism is essential. Blood vessels in the lungs can suddenly become blocked, reducing blood flow and putting strain on the heart, which can be fatal if untreated. Common…

City of Hope®, one of the nation’s largest and most advanced cancer research and treatment institutions, home to a national medical center ranked among the nation’s top cancer centers by U.S. News & World Report, has launched an innovative Phase 2 clinical trial aimed at mapping how tumors change when they begin to resist immunotherapy, a treatment that improves the immune system’s ability to fight disease. This study will focus on advanced non-small cell lung cancer (NSCLC), the most common type of lung cancer, accounting for 87% of cases. The six-year IMMUNO-BIOMAP trial, which aims to enroll 535 patients with…

A study examining the association between emotional attachment, mentalizing ability, and hypersexual behavior found that among people with high sexual desire, attachment anxiety and avoidance (i.e., attachment anxiety) were associated with hypersexual behavior. People with higher mentalizing abilities were less likely to engage in excessive sexual behavior. The paper was published in. Journal of Sex Research. Mentalization is the ability to understand one’s own and others’ actions in terms of their underlying thoughts, feelings, intentions, and desires. This ability develops through early attachment relationships in which caregivers help children recognize, label, and regulate their internal states. However, because caregivers tend…
