How credible are the findings of a new published study linking omega 3 supplementation to prostate cancer risk?

Not at all: The study was an association between blood levels of omega 3's and prostate cancer. It was not a study showing that taking omega 3's causes or increases the risk of prostate cancer. There has been no study to show omega 3's cause prostate cancer. Don't get your medical information from friends, tv or the internet. ...Read more

Unusually high level: of the signaling peptide BDNF (brain-derived neurotrophic factor) have been detected in children w/ autism. BDNF regulates birth and differentiation of brain cells (neurons). Barbara Hempstead et al (Weill Medical College, Cornell Univ) propose that BDNF may be over-expressed in the brains of these children, causing neurological defects that lead to the disorder but causation not yet proven. ...Read more

The article that purported to show this has been retracted. Millions of dollars have been spent looking for this link and not a single link has been found.

Low-level ionizing radiation from noninvasive cardiac imaging: can we extrapolate estimated risks from epidemiologic data to the clinical setting?

Low-level ionizing radiation from noninvasive cardiac imaging: can we extrapolate estimated risks from epidemiologic data to the clinical setting?

extrapolation: Your question remains a subject of controversy today. We assume that total exposure to ionizing radiation is a correlate of risk of complications from all kinds of testing exposures. This is why we try and limit radiation testing procedures to use when the data is really needed in decision making. ...Read more

Comparison is made to previous studies

 

 

 

The mammary tissue is heterogeneously dense which lowers the sensitivity of mammography. Apparently new compared to previous studies is a smoothly marginated 7mm low density ovoid nodule a

I don't have the : full report, but it sounds like there might be a new finding on screening mammography. The next step is usually a more complete imaging evaluation with diagnostic mammography and probably ultrasound. A final diagnostic code(BIRADS) for the nodule will be determined based on the imaging findings: benign(no followup),probably benign(6 month f/u), suspicious, highly suspicious( needle biopsy ) ...Read more

Why would there be a huge increase in autism and retardation in the population?

Why would there be a huge increase in autism and retardation in the population?

Multifactorial: Because the presentation of autism spectrum disorders is so varied and the incidence is increasing significantly the effect of environmental factors on genetics is proving to play a big role. They are many subtle ways the environment can afffect the expression of certain genes and we are learning of new genetic variants constantly. Protect your environment to protect your genes. ...Read more

My B12 levels were 981 ng/L (range 191 -900) a few months ago & Folate 19 ug/L (range 3.8 -20). Pregnant now & worried re: the studies linking autism.

No worries: Autism is a set of symptoms without proven causes, and will likely be found to be several different disorders with a variety of causes. Meanwhile, there will be news of "possible" links to this or to that, as each year goes by. Someday, there will be proven links and proven causes. As always, everything in moderation, meaning take prenatal vitamins but don't overdo it, and eat a variety of foods. ...Read more

Has it been looked into if an abundance of vitamin K in the blood causes autism? I know the study was of a deficiency of the vitamin. Thank you.

Has it been looked into if an abundance of vitamin K in the blood causes autism? I know the study was of a deficiency of the vitamin.  Thank you.

How to say this...: I'm glad you asked the question here. In 2006, someone in the not-so-mainstream world of unproven " biomedical" cures for autism, like treating yeast , thought that giving vit k would be curative. Later, someone decided that vitamin k shots given to newborns since i-don't- know-when were a cause of autism , claiming they were dissolved in a base..Or an acid..Or both..

ASD many factors: Fortunately, the incidence of autism spectrum disorder is generally only 1-2 %, and although there appears to be increase in frequency, there is also more awareness which leads to increased diagnosis. The Swedish study suggested a 59% increase in women with PCOS, which brings the likelihood from 1-2% to 1.6-3.2%. Still a 97% chance your child will NOT have Autism as many women with pcos attest ...Read more

Its not contagious,: if that's what you mean. There are genetic links that run in families, so in that sense there is greater likelihood of ending up with autism or something related if one or more of your biological parents have it. But, genetics is very far away from being able to predict what child will get it, given the parent's symptoms. If this is your concern, find a genetic counselor for the latest... ...Read more

What is an "autism stare"?

Uncomfortable gaze: Kids with autism are uncomfortable with eye contact. They can learn in therapy to make eye contact and often what happens is they can develop a trained "stare" in which they are trying to make eye contact (which is terribly innately uncomfortable for them) and they end up " over doing it" so to speak. I think this is what you are referring to. ...Read more
