How much vitamin D do you need? Distilling strong advice from weak evidence
Vitamin D is a steroid hormone and a component of a complex endocrine pathway sometimes called 'vitamin D endocrine system' (Medscape, 2012).From Nature News:
Vitamin D has been lauded in the media for preventing or treating multiple disease but most evidence is circumstantial or weak.
Despite this, some physicians recommend supplementation of up to 6,000 international units (IU) to compensate for the time that people spend indoors. This is less than what a fair-skinned person make in 30 minutes of exposure to the summer sun (without sunscreen).
The amount spent on vitamin-D supplements in the United States had risen 10-fold in 10 years.
Poor data is one reason that the IOM panel did not recommend higher doses for vitamin D supplementation in 2010. The IOM 1,000-page report recommended that people should aim for blood levels of 50 nanomoles per litre (nmol/L).
However, according to the Endocrine Society's guidelines:
- people with levels under 50 nmol/L are "vitamin-D deficient"
- those with levels between 50 nmol/L and 72.5 nmol/L are "insufficient"
The society's guidelines also offer an 'ideal' level of 100–150 nmol/L which would require 1,500–2,000 IU daily. It advises physicians to monitor vitamin-D levels in healthy people.
Quest Lab already began to implement these deficiency and insufficiency standards over the IOM's. Many physicians are expected to follow suit.
A vitamin D3 dosage of 800 IU/d increased serum 25-(OH)D levels to greater than 50 nmol/L in 97.5% of women http://bit.ly/GzBCcA

Neil Mehta - This sounds like deja vu' all over again. How many times have we been down this path? vitamin C, Vitamin E, Carotenes....
Common themes:
The myth of natural products: "it is a natural product so it can't cause harm can it?" Thus if a little bit of it is good, more must be better.
The research problem: "It is over the counter and present in foods so very difficult to determine how much someone is actually taking"
Huge confounder of observational studies: "People who take supplements, other "health products" are different from those who don't.
What happens when you ask for medical advice on Twitter - CNN's Anderson Cooper knows from experience
What happens when you ask for medical advice on Twitter and you are CNN's host Anderson Cooper with 1.5 million followers:

@thehighsign I generally just go with the opinion of a million and a half strangers.
@SashaTalebi Crazy times we're living in when @andersoncooper can crowdsource his bronchitis diagnosis via Twitter. Get well soon.
@JPLondon72 When a doctor says "You have bronchitis". Usually. Not always.
@emokidsloveme I feel like @andersoncooper has health insurance. Call me crazy, but I think he could afford to pay out of pocket too. #TwitterER
@Technikohler But why don't you just hit up good ole Gupta and ask him ?
@SadaoTurner hey @sanjayguptaCNN, do u know this guy @andersoncooper
@sherrybutlerpr Tight breathing, Burning in chest, fever. B careful, walking pneumonia
@LizaLizzieHalim i knew when i had troubled breathing&it makes sounds.Then i get the doctor checked&was diagnosed with it. Still have it now.
@lynngosselin I've had bronchitis many times so yes I know...but maybe a Dr. will pick up your post

@sherrybutlerpr Also coughing up phlegm. Get on meds. U don't slow down, so will need that or will really go down. Take good care.

Acute bronchitis: Many patients expect to be treated with antibiotics and cough meds but this differs from guidelines
Mind map of differential diagnosis of cough. See more Allergy and Immunology mind maps here.
Cough is the most common symptom bringing patients to the primary care physician's office. The most common diagnosis in these patients is acute bronchitis, according to a recent review in the official journal of AFP, American Family Physician.
Acute bronchitis should be differentiated from other common causes of cough such as pneumonia and asthma - because the therapies are clearly different.
Symptoms of acute bronchitis typically last 3 weeks. As we already know, the presence of colored (e.g., yellow or green) sputum does not reliably differentiate between bacterial and viral lower respiratory tract infections. This statement was contradicted by a recent study: Green or yellow phlegm likely to be bacterial - confirming beliefs by doctors and patients alike (http://goo.gl/zff8X and http://goo.gl/cwKGs).
Viruses cause more than 90% of acute bronchitis, and therefore, antibiotics are generally not indicated. They should be used only if pertussis is suspected to reduce transmission or if the patient is at increased risk of developing pneumonia (e.g., patients 65 years or older).
The typical therapies that have been traditionally used for managing acute bronchitis symptoms have been shown to be ineffective. The U.S. Food and Drug Administration recommends against using cough and cold preparations in children younger than 6 years.
The supplement pelargonium may help reduce symptom severity in adults.
Many patients expect to be treated with antibiotics and cough medications but this differs from evidence-based recommendations.
