Protect kids from toxic secondhand smoke, experts urge

second hand smoke

second hand smoke

It’s advice most smokers with children probably take lightly, but they shouldn’t. Parents and policy advocates should take a “zero tolerance” approach to exposing children to secondhand cigarette smoke, which can be responsible for lifelong cardiovascular consequences in addition to respiratory and other health issues.

Household dust exposes people to a wide range of toxic chemicals from everyday products, according to a new study. A multi-institutional team conducted a first-of-a-kind meta-analysis, compiling data from dust samples collected throughout the United States to identify the top ten toxic chemicals commonly found in dust.

Breastfeeding associated with better brain development and neurocognitive outcomes

breastfeeding makes for one smart looking baby

A new study, which followed 180 preterm infants from birth to age seven, found that babies who were fed more breast milk within the first 28 days of life had had larger volumes of certain regions of the brain at term equivalent and had better IQs, academic achievement, working memory, and motor function.

Mothers with diabetes more likely to have anti-fetal brain autoantibodies

Mothers of children with autism and were diagnosed with metabolic conditions during pregnancy, particularly gestational and type 2 diabetes, were more likely to have anti-fetal brain autoantibodies in their blood compared to healthy women of children with autism. The presence of these anti-fetal brain autoantibodies has been previously found to be specific to some mothers of children with autism and rare among mothers of children without autism.

Too much cellular ‘noise’ can affect brain development

Wrong kind of noise…

Using cutting-edge imaging technology, biologists have determined that uncontrolled fluctuations (known at “noise) in the concentration of the vitamin A derivative Retinoic acid (RA) can lead to disruptions in brain organization during development. Identifying how a cell responds to a signal made by another cell, despite the level of noise present, may improve our understanding of developmental disorders.

REM sleep critical for young brain development; medication interferes

REM sleep and dreaming

Rapid eye movement or REM sleep actively converts waking experiences into lasting memories and abilities in young brains reports a new study. The finding broadens the understanding of children’s sleep needs and calls into question the increasing use of REM-disrupting medications such as stimulants and antidepressants.

These days pregnant “moms to be” have lots of things to worry about, from second hand smoke to the chemicals in their make-up. Well they can unfortunately add one more thing to that list, a new study finds that alcohol drunk by a mouse in early pregnancy changes the way genes function in the brains of the offspring. The early exposure was also later apparent in the brain structure of the adult offspring. The timing of the exposure corresponds to the human gestational weeks 3-6 in terms of fetal development.

Brain development suffers from lack of fish oil fatty acids

While being inundated with advertisements directed at moms to be, skeptical parents should question the supposed health benefits of anything being sold. However, while recent reports question whether fish oil supplements support heart health, scientists have found that the fatty acids they contain are vitally important to the developing brain. Meaning there might actually be truth in advertising — this time at least.
