CDC’s Recommended Salt Intake Linked Poorer Health

A new study published in the American Journal of Hypertension, published by Oxford Univ. Press USA, finds evidence that the average daily sodium intake of most Americans is actually associated with better health outcomes than intake levels currently recommended by the CDC and major health departments, which are now being viewed by many in the scientific community as excessively and unrealistically low.

The study concluded that 2,645 – 4,945 mg of sodium per day, a range of intake within which the vast majority of Americans fall, actually results in more favorable health outcomes than the CDC’s current recommendation of less than 2300mg/day for healthy individuals under 50 years old, and less than 1,500 mg/day for most over 50 years. This study was a combined analysis of 25 individual studies, which measured results from over 274,683 individuals.

Confirmation de deux nouveaux cas de rougeole à Ottawa

ottawasante:

Santé publique Ottawa (SPO) enquête sur deux nouveaux cas de rougeole. Ces deux nouveaux cas, l’un chez un enfant non immunisé et l’autre chez un adulte immunisé, ont été en contact avec un cas initial de rougeole. Des cas comme ceux-ci ne sont pas surprenants, puisque la rougeole est une maladie respiratoire très contagieuse dans la mesure où pratiquement toutes les personnes qui n’ont pas été immunisées et sont exposées au virus seront infectées. Depuis le 5 mars dernier, quatre cas de rougeole ont été confirmés à Ottawa.

Les personnes qui se trouvaient dans les endroits suivants aux heures indiquées risquent d’avoir été exposées au virus de la rougeole; Santé publique Ottawa leur recommande donc de consulter leur fournisseur de soins de santé si elles sont incertaines quant à leur état d’immunisation :

  • le 18 mars 2014, entre 13 h 15 et 15 h 30 : Restaurant Subway, 700, chemin March;
  • le 20 mars 2014, entre 18 h et 20 h 40 : Shoppers Drug Mart, 1300, rue principale Stittsville;
  • le 21 mars 2014, entre 6 h 30 et 10 h : Sportsplex de Nepean, 1701, avenue Woodroffe;
  • le 21 mars 2014, entre 11 h 30 et 14 h : Restaurant Quizno’s, 4048, rue Carling ;
  • le 21 mars 2014, entre 9 h et 17 h 30, Commerces situés au 411, promenade Legget.

Santé publique Ottawa invite toutes les personnes qui se trouvaient aux endroits en question aux heures susmentionnées à communiquer avec Info-santé publique Ottawa au 613 580-6744 si elles :

  • ne sont pas immunisées;
  • ont un système immunitaire affaibli;
  • sont enceintes, ou;
  • travaillent dans le secteur des soins de santé ou de garde d’enfants;
  • étaient accompagnées d’un enfant de moins d’un an à l’un des endroits susmentionnés.

Les premiers symptômes de la rougeole comprennent la fièvre, de la toux, de petites taches à centre blanc dans la bouche. De trois à sept jours plus tard, des plaques rouges apparaissent sur le visage, avant de s’étendre jusqu’aux bras et aux jambes. Si vous pensez être atteint de rougeole, vous devriez vous isoler en restant chez vous et en évitant tout contact avec des personnes non immunisées. Appelez votre médecin avant d’aller le consulter de façon à ce qu’il prenne les précautions nécessaires pour protéger ses autres patients.

Le virus de la rougeole se propage par les gouttelettes expulsées ou par contact direct avec une personne infectée. Beaucoup plus grave chez les nourrissons et les adultes que chez les enfants, cette maladie peut entraîner une infection d’oreilles, une pneumonie, un œdème cérébral, ou même la mort du patient. Nous encourageons fortement tous les résidents à envisager de se faire vacciner, eux et leur famille, pour se protéger contre la rougeole et d’autres maladies pouvant être prévenues par un vaccin […]

Le tabagisme, même passif, affecte le foetus

Large Study Shows Smoking Harms Fetuses

Tobacco smoke contains thousands of compounds, many of them toxic and capable of causing injury throughout the body. Because of this high toxicity of tobacco smoke, many diseases have long been causally linked to tobacco smoking – both to active smoking and to passive exposure of non-smokers who inhale the mixture of exhaled smoke and smoke given off by the smoldering cigarette, generally referred to as secondhand smoke or SHS.

The journal Tobacco Control recently published findings on smoking and pregnancy outcomes from a very large U.S. study, the Women’s Health Initiative. The authors assessed whether active smoking by the mother while pregnant and exposure of non-smoking mothers to SHS led to an increased risk of spontaneous abortion, stillbirth and tubal ectopic pregnancy (that is, implantation of the fertilized egg into the fallopian tube, rather than the uterus). Overall, the study found that both active smoking and SHS exposure increased all of these risks for pregnancy.

Une main bionique qui permet de “sentir”

neuromorphogenesis:

Bionic hand allows patient to ‘feel’

Dennis Aabo was able to feel what was in his hand via sensors connected to nerves in his upper arm

Scientists have created a bionic hand which allows the amputee to feel lifelike sensations from their fingers.

A Danish man received the hand, which was connected to nerves in his upper arm, following surgery in Italy.

Dennis Aabo, who lost his left hand in a firework accident nearly a decade ago, said the hand was “amazing”.

In laboratory tests he was able to tell the shape and stiffness of objects he picked up, even when blindfolded.

The details were published in the journal Science Translational Medicine.

Implant

An international team carried out the research project, which included robotics experts from Italy, Switzerland and Germany.

"It is the first time that an amputee has had real-time touch sensation from a prosthetic device" said Prof Silvestro Micera from the Ecole Polytechnique Federale de Lausanne and Scuola Superiore Sant’Anna, Pisa.

The scientific advance here was not the hand itself, but the electronics and software that enabled it to give sensory feedback to the brain.

Micera and his team added sensors to the artificial hand which could detect and measure information about touch. Using computer algorithms, the scientists transformed the electrical signals they emitted into an impulse that sensory nerves could interpret.

During an operation in Rome, four electrodes were implanted onto nerves in the patient’s upper arm. These were connected to the artificial sensors in the fingers of the prosthetic hand, so allowing touch and pressure feedback to be sent direct to the brain.

Mr Aabo, 36, a property developer, spent a month doing laboratory tests, firstly to check the electrodes were functioning, and then with these fully connected to the bionic hand.

He said: “The biggest difference was when I grabbed something I could feel what I was doing without having to look. I could use the hand in the dark.

"It was intuitive to use, and incredible to be able to feel whether objects were soft or hard, square or round."

Hero

The bionic hand is still a prototype, and due to safety restrictions imposed on clinical trials, Mr Aabo required a second operation to remove the sensors.

"He is a hero," said Professor Paolo Rossini, neurologist, University Hospital Agostino Gemelli, Rome.

"He gave a month of his life and had two operations to test this device.

"We are all very grateful to him."

Prof Rossini said a lot of pre-training was done involving surgery on pigs, and with human cadavers, to ensure they knew exactly how to attach electrodes to the tiny peripheral nerves in the upper arm.

Another member of the team, Dr Stanisa Raspopovic said: “It was a very exciting moment when after endless hours of testing….Dennis turned to us and said with disbelief, ‘This is magic! I can feel the closing of my missing hand!’”

Those working in the field in the UK were also enthusiastic.

"This is very interesting work, taking research in upper limb prosthetics into the next stage by adding sensory feedback, said Dr Alastair Ritchie, Lecturer in Biomaterials and Bioengineering, University of Nottingham.

"This technology would enable the user to know how firmly they are gripping an object, which is vital for handling fragile objects - imagine picking up an egg without any feeling in your fingers."

The international team is now working on how to miniaturise the technology so that it could be used in the home.

"We must get rid of the external cables and make them fully implantable" said Prof Thomas Stieglitz, University of Frieburg, Germany, whose laboratory created the ultra-thin implantable electrodes.

Recently, scientists in Cleveland, Ohio released a video of a patient using the fingers of a prosthetic hand to pull the stalks from cherries while blindfolded. But the research has not yet been published in a peer-reviewed journal.

There is no precise timetable, but scientists think it could be a decade before a sensory feedback bionic hand is commercially available.

And they believe it may pave the way for more realistic prosthetic devices in the future which can detect texture and temperature.

'Bring it on'

But it will undoubtedly be very expensive, well beyond the means of most patients. And artificial hands still lack the precision and dexterity of the real thing.

The super-functioning bionic hand of science fiction films remains the stuff of fiction.

Nonetheless, Dennis Aabo, who now has his old prosthesis back, is ready to swap it for the bionic hand in any future trial.

"If they offer it to me, I will say bring it on, I’m ready."
