‘Miniature’ MRI scanner for babies.

Miniature size scanner means minimal movement of newborns, dramatically reducing risk to babies while providing e more detailed clinical information than bedside ultrasound scans.

Clinicians ..more often underestimated harms and overestimated benefits od drugs, and understimate the power of nutrition and preventive medicine (= lifestyle).

Do clinicians have accurate expectations of the benefits and harms of treatments, tests, and screening tests?

In a systematic review of 48 studies (13. 011 clinicians), most participants correctly estimated 13% of the 69 harm expectation outcomes and 11% of the 28 benefit expectations. The majority of participants overestimated benefit for 32% of outcomes, underestimated benefit for 9%, underestimated harm for 34%, and overestimated harm for 5% of outcomes. Clinicians rarely had accurate expectations of benefits or harms, with inaccuracies in both directions, but more often underestimated harms and overestimated benefits.

Come perdere mezzo quintale di peso senza ricorrere alla chirurgia.

Intervista scritta a Tiziana Fumei (sotto al video).

E' interessante notare che, quando si tratta di perdere peso,
1) non ci sono scorciatoie o formule magiche;
2) al contrario è un impegno costante, giorno per giorno sia per perdere sia per mantenere il peso.

I gruppi di #automutuoaiuto sono una risorsa unica, più importante di un dietologo o un dietista o della stessa forza di volontà di un individuo.

Superhydrophobic –or water repellent–materials are much sought after. Their remarkable ability to shed water is actually mechanical in nature–not chemical. Surfaces with a highly textured microstructure, like a lotus leaf or a butterfly wing, shed water naturally because air trapped between the high points prevents the water from contacting most of the solid surface.

The result is that a drop sitting on the surface will have a very high contact angle and be nearly spherical. Instead of wetting the surface and spreading out, it can slide right off, as seen in the animation below. Here researchers have treated the coins  with a spray-on coating that creates superhydrophobic microscale roughness. Similar coatings are commercially available, but such coatings are delicate and lose their hydrophobicity over time as the microstructure breaks down.

Denmark’s 29,000 Doctors Declare Circumcision of Healthy Boys an “Ethically Unacceptable” Procedure Offering no Meaningful Health Benefits.

Internationally, several medical associations have issued policies and recommendations that contradict the popular belief in the United States that infant male circumcision is a harmless, health-promoting procedure. In fact, not one medical association in the whole world recommends circumcision of healthy boys.

Vitamin D Deficiency Increases Risk of Chronic Headache

Vitamin D deficiency may increase the risk of chronic headache, according to a new study from the University of Eastern Finland. The findings were published in Scientific Reports.

The Kuopio Ischaemic Heart Disease Risk Factor Study, KIHD, analysed the serum vitamin D levels and occurrence of headache in approximately 2,600 men aged between 42 and 60 years in 1984–1989. In 68% of these men, the serum vitamin D level was below 50 nmol/l, which is generally considered the threshold for vitamin D deficiency. Chronic headache occurring at least on a weekly basis was reported by 250 men, and men reporting chronic headache had lower serum vitamin D levels than others.

When the study population was divided into four groups based on their serum vitamin D levels, the group with the lowest levels had over a twofold risk of chronic headache in comparison to the group with the highest levels. Chronic headache was also more frequently reported by men who were examined outside the summer months of June through September. Thanks to UVB radiation from the sun, the average serum vitamin D levels are higher during the summer months.

The study adds to the accumulating body of evidence linking a low intake of vitamin D to an increased risk of chronic diseases. Low vitamin D levels have been associated with the risk of headache also by some earlier, mainly considerably smaller studies.

In Finland and in other countries far from the Equator, UVB radiation from the sun is a sufficient source of vitamin D during the summer months, but outside the summer season, people need to make sure that they get sufficient vitamin D from food or from vitamin D supplements.

As yourself a question how far are you willing to go...

An Afro-Caribbean having a child with Caucasian or Asian

Two people having Cystic fibrosis gene (end result is a child with cystic fibrosis and life expectancy is around 37 years)

A sperm and an egg are genetically modified to prevent a child being born with down's syndrome or cystic fibrosis...

Which would you be willing to compromise? Would you stop at all?

If you knew all methods are safe why would you oppose modifying less complex organisms like fruit or veg...
