New blood biomarker predicts progression of Alzheimer's disease even in its earliest stages

The human brain is comprised of two main types of cells, known as neurons and glia. The first are responsible for transmitting electrical and chemical signals, while the latter support and protect neurons.

Australian scientists have successfully developed a research system that uses 'biological artificial intelligence' to design and evolve molecules with new or improved functions directly in mammal cells. The researchers said this system provides a powerful new tool that will help scientists develop more specific and effective research tools or gene therapies.

Liquid biopsies are tests that detect signs of cancer through a simple blood draw. Unlike traditional biopsies, which require removing a piece of tissue, a liquid biopsy typically looks for mutations or modification changes in fragments of DNA from cancer cells circulating in the blood.

Access to obstetric care is a critical determinant of maternal and infant health. However, a new study led by the University of Minnesota School of Public Health found that hospital-based obstetric care has declined in recent years, with variability across states.

A paper in the British Journal of Surgery indicates that early-onset gastrointestinal cancer rates are rising dramatically across the globe.

Finding motivation to exercise can be the greatest challenge in working out. This might be part of the reason why less than a quarter of people achieve the activity goals recommended by the World Health Organization.

The efficacy and safety of currently approved and pipeline medications for moderate-to-severe hidradenitis suppurativa (HS) are compared in a systematic literature review and network meta-analysis published online July 2 in JAMA Dermatology.

The German Institute for Quality and Efficiency in Health Care (IQWiG) has examined the pros and cons of biomarker-based tests to inform decisions about adjuvant chemotherapy for patients with a certain type of breast cancer, i.e., first-time, hormone receptor-positive and HER2/neu-negative breast cancer.

Researchers at the Max Planck Institute for Human Development have critically examined the basis for a frequently cited figure: that people make more than 200 unconscious decisions about food every day. This figure has circulated in scientific publications, the media, and health promotion campaigns for nearly 20 years without ever being empirically validated. An article published in the journal Appetite shows why a more nuanced view of eating behavior is needed.

Researchers at the University of Tartu Institute of Genomics have gained a deeper understanding of why some people are more prone to experiencing side effects when taking antidepressants.

Within months of Pennsylvania's medical cannabis program adding anxiety as a qualifying condition, that diagnosis quickly rose to become the most common for cannabis certifications, according to a study by researchers at the University of Pittsburgh and Johns Hopkins University. The study was published in Annals of Internal Medicine.

A cross-sectional and longitudinal analysis examined the distribution of people by obesity level using the European Association for the Study of Obesity's (EASO) new framework and determined the risk of death of those newly diagnosed with obesity by this framework.

In Florida, adolescent handgun-carrying is increasing, while handgun-carrying in school, favorable attitudes toward handgun0carrying in school, and ease of handgun access are decreasing, according to a study published online July 7 in Pediatrics.

Researchers have provided robust scientific evidence that ailments like depression, high blood pressure, diabetes mellitus, Alzheimer's disease, osteoarthritis, and difficulties performing daily activities are associated with a frail handgrip, particularly among older adults.

Patients undergoing retinal detachment (RD) repair with concomitant cannabis use have a lower risk of subsequent proliferative vitreoretinopathy (PVR) and requiring subsequent complex RD repair, according to a study published online July 3 in JAMA Ophthalmology.

A new study from Aarhus University turns our understanding of how running injuries occur upside down. The research project, which is the largest of its kind ever conducted, shows that running-related overuse injuries do not develop gradually over time, as previously assumed, but rather suddenly—often during a single training session. The research is published in the British Journal of Sports Medicine.

Two babies in Oregon became ill with lead poisoning after eating baby food from Target that had been previously recalled, Oregon health officials said.

Adults as young as 50 may now qualify for an RSV vaccine if they have certain health conditions, according to a quiet update from the U.S. Centers for Disease Control and Prevention (CDC).
