How does the brain make sense of what we see, hear and feel, and transform these separate signals into a coherent perception of the world?

Newborns receive several routine immunizations shortly after birth. Prophylactic vitamin K is one such recommended shot. It activates several coagulation factors necessary for blood to clot properly, preventing vitamin K deficiency bleeding (VKDB), a condition that can be life-threatening. As more parents refuse prophylactic vitamin K for their children, researchers in Sweden wanted to examine trends in newborn vitamin K shots over time and any associations with infant bleeding diagnoses.

A study led by the Barcelona Institute for Global Health (ISGlobal), an institution supported by the "la Caixa" Foundation, found no increased risk of miscarriage, stillbirth or major congenital anomalies among women inadvertently exposed to ivermectin from two weeks before conception through the first four weeks of pregnancy. The findings, published in eClinicalMedicine, add to the available evidence on the safety of this antiparasitic drug during the very early stages of pregnancy, although the researchers stress that the number of cases remains too small to warrant changes to current recommendations.

Emergency departments across the country face a common challenge: how to reduce long wait times without adding more beds, hiring more staff or expanding facilities. New research suggests one answer may be hiding in plain sight—making better decisions about where patients receive care.

The main function of CRISPR-Cas systems is to defend bacteria against various threats, including viruses called bacteriophages. Researchers have continued to study all varieties of CRISPR-Cas systems (to date, two classes, seven types and 46 subtypes have been identified) to understand their capabilities.

Exposure to secondhand cigarette smoke during the first days of life can cause changes in tooth enamel mineralization without causing visible changes to the teeth. This was demonstrated in an animal model study conducted by researchers at the Ribeirão Preto School of Dentistry at the University of São Paulo (FORP-USP) in Brazil. The results were published in May in the scientific journal Calcified Tissue International.

An evidence review of international research suggests widespread misconceptions within the medical community about early milk production, pacifiers and breast pumps may be undermining breastfeeding success in the critical first days after birth.

Fertilization is often imagined as a frantic race, with millions of sperm competing for a single prize. But new research by a team of evolutionary biologists from Syracuse University, University of Siena, Italy, and University of Szeged, Hungary, reveals a more surprising reality, where success can depend less on competition and more on cooperation.

The North American Spine Society has released evidence-based clinical guidelines and appropriate use criteria for antithrombotic therapies in adults undergoing spine surgery, according to a press release.
“These are very useful documents. They are reasonably concise, comprehensive and up to date. They are not meant to represent standard of care, nor do they replace provider judgment and experience along with patient values. However, they can assist in decision making in a very meaningful way. Where the evidence is robust either for or against an intervention, those recommendations should
