In what is surely good news in regards to peanut allergies, we’re learning that early exposure to peanuts can help prevent later allergic reactions, and this protection persists even after a year of avoiding peanuts.
The LEAP-On study was an extension of the ITN’s landmark LEAP Study (Learning Early About Peanut Allergy), which demonstrated that regular peanut consumption begun in early infancy and continued until age 5 reduced the rate of peanut allergy in at-risk infants by 80% compared to non-peanut-consumers. LEAP was the first large, well-controlled study to conclusively show the benefits of early peanut consumption in this population, changing previous notions about peanut allergy prevention.
Of 84 recruited patients, 80 (95.2%) completed the study. Thirty-seven (46.3%) received nasally inhaled isopropyl alcohol and 43 (53.8%) received nasally inhaled normal saline solution. At 10 minutes postintervention, median nausea verbal numeric response scale score was 3 in the isopropyl alcohol arm versus 6 in the placebo arm, for an effect size of 3 (95% confidence interval 2 to 4).
The lizards, discovered in private amber collections on loan to the American Museum of Natural History and Harvard University, are immaculate and unusually diverse. As such they suggest that major lizard groups were already established at that time. The specimens will now go on display at the Houston Museum of Natural Science.
Hoping to help scientists better understand the effects of repeated head trauma, US soccer star Brandi Chastain has stated she will donate her brain to science.
“Hopefully, what can be learned is, can doctors and scientists and neuroscientists look at the brain of someone like me, who has been playing soccer a majority of my life, and really dissect the brain and say, ‘Here’s where we see it beginning?’ Could we then use that information to help say that before the age of 14, it’s not a good idea to head the ball?'” Chastain told USA Today.
Ultrasonographic examination that was performed at 29 weeks of gestation showed the first signs of fetal anomalies, and she was referred to the Department of Perinatology. At that time, she also noticed reduced fetal movements. Ultrasonography that was performed at 32 weeks of gestation confirmed intrauterine growth retardation (estimated third percentile of fetal weight) with normal amniotic fluid, a placenta measuring 3.5 cm in thickness (normal size) with numerous calcifications, a head circumference below the second percentile for gestation (microcephaly), moderate ventriculomegaly, and a transcerebellar diameter below the second percentile.
From Science magazine comes news of a fungus which turns frogs into sexy zombies. And what, exactly, does it mean for a frog to be a sexy zombie? Well, “A fungal disease that has killed amphibians worldwide may be spreading by making the mating calls of infected males more attractive to females.”
The fungus, known as Batrachochytrium dendrobatidis (Bd), causes disruptions of the immune system, destroys skin, and causes heart failure. And while there is evidence of some frog species adapting to the 40,000 year old fungus, others are being killed off due to lack of defenses. For more details on the fungus and its impact on amphibians, see the full article at Science magazine’s web site.
