Foreign workers in the Heath care system
"It also emerged it costs the NHS £70,000 to train a nurse for three years – but for the same amount it could hire three qualified foreigners on an average salary of £23,000."

Désarroi d'un chirurgien américain
Beaucoup de chirurgiens américains sont salariés! 1/3 fixe 2/3 variable ou l'inverse, c'est contractuel.
Mais ce qui est vrai c'est qu'il existe une énorme bureaucratie dont une des raisons est la question des facturations analytiques et non forfaitaires mais aussi la pression énorme des claims qui obligent à tout tracer.
Venons en à notre pays. Avec un seul opérateur et des systèmes très forfaitisés nous avons aussi une croissance énorme de la bureaucratie dans les hôpitaux pour d'autres raisons.
1/ le droit du travail qui phagocyte la fonction de cadre alors que la "raison d'être" d'un cadre est l'organisation du travail et la productivité.
2/ une hypertrophie génétique de l'administration française puisque les hôpitaux ne sont pas autonomes à aucun point de vue mais sont des officines d'état.
3/ la malheureuse "réforme" Juppé des ARS qui est une bureaucratisation rampante de la santé avec une volonté de planisme parfaitement inadapté à cette économie du soins qui va de disruption en disruption.

Microchimerism a durable link between mother and son
http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0045592
It is an amazing story:
"In this study, we provide the first description of male Mc in female human brain and specific brain regions. Collectively with data showing the presence of male DNA in the cerebrospinal fluid [32], our results indicate that fetal DNA and likely cells can cross the human blood-brain barrier (BBB) and reside in the brain. Changes in BBB permeability occur during pregnancy [33]and may therefore provide a unique opportunity for the establishment of Mc in the brain. Also unique to our study are the findings that male Mc in the human female brain is relatively frequent (positive in 63% of subjects) and distributed in multiple brain regions, and is potentially persistent across the human lifespan (the oldest female in whom male DNA was detected in the brain was 94 years)."
And the following is more disturbing:
"The most likely source of male Mc in female brain is acquisition of fetal Mc from pregnancy with a male fetus. In women without sons, male DNA can also be acquired from an abortion or a miscarriage [22], [23], [38]–[40]. The pregnancy history was unknown for all but a few subjects in the current studies, thus male Mc in female brain could not be evaluated according to specific prior pregnancy history. In addition to prior pregnancies, male Mc could be acquired by a female from a recognized or vanished male twin [41]–[43], an older male sibling, or through non-irradiated blood transfusion [44]."
"During pregnancy, genetic material and cells are bi-directionally exchanged between the fetus and mother [1], following which there can be persistence of the foreign cells and/or DNA in the recipient [2], [3]. This naturally acquired microchimerism (Mc) may impart beneficial or adverse effects on human health. Fetal Mc, which describes the persistence of cells and/or DNA of fetal origin in the mother acquired during pregnancy, has been associated with several different autoimmune diseases as well as implicated in tissue repair and immunosurveillance [4]–[6]."
