Pertussis, also known as "whooping cough," remains a significant cause of death in infants and young children around the world and, despite global vaccination programs, many countries are experiencing a resurgence of this highly contagious disease. A new study by Boston University School of Public Health and the University of Georgia's Odum School of Ecology presents evidence that could help explain this resurgence: asymptomatic individuals. Lots of them.
An intrauterine fracture is a rare finding during routine prenatal imaging. This condition can be due to maternal trauma, genetic disorders of the skeleton, as well as other predisposing maternal metabolic and vascular disorders. Genetic disorders that have previously been reported to cause intrauterine fracture include brittle bone disease (osteogenesis imperfecta or OI), osteopetrosis, hypophosphatasia and Ehlers-Danlos syndrome (EDS).
Research published today in the journal Cell is the first to establish how a specific gut bacterium, activated Bifidobacterium infantis EVC001 (B. infantis), influences immune system development in infants, and could thereby reduce the risk of allergic and autoimmune conditions later in life.
Many diseases caused by a dysregulated immune system, such as allergies, asthma and autoimmunity, can be traced back to events in the first few months after birth. To date, the mechanisms behind the development of the immune system have not been fully understood. Now, researchers at Karolinska Institutet show a connection between breast milk, beneficial gut bacteria and the development of the immune system. The study is published in Cell.
What The Study Did: Researchers estimated survival and other outcomes of very preterm infants in China discharged against medical advice from neonatal intensive care units before complete care can be provided compared with infants who receive full intensive care treatment.
When delivering moms require caesarians or their newborns need neonatal care, some families may spend as much as $10,000 out-of-pocket, according to a new Michigan Medicine-led study.
Researchers from University of Tsukuba, in collaboration with scientists in Germany, have created a mouse model of restrictive cardiomyopathy, a disease in which the heart muscle becomes stiff and the heart is unable to properly fill with blood. Their data suggest that the disease results from the accumulation of mutant BAG3 protein, which interferes with the protein quality control system and the machinery for breaking down and recycling damaged proteins, disrupting the heart muscle components.
Brazilian researchers show that a combination of inflammatory cytokines in the blood and cannabis use, daily or during adolescence, heightens the odds of developing psychiatric disorders.
Researchers at Karolinska Institutet in Sweden found industrial chemicals in the organs of fetuses conceived decades after many countries had banned the substances. In a study published in the journal Chemosphere, the researchers urge decision makers to consider the combined impact of the mix of chemicals that accumulate in people and nature.
Corticosteroids may be an effective treatment for children who develop a rare but serious condition after COVID-19 infection.
