EULAR studies focus on vitamin D
Jul 29, 2015

Vitamin D has gained interest within many specialties, as well as in general practice. As such, the results of a number of studies focused on vitamin D in numerous rheumatic diseases were presented at the European League Against Rheumatism, or EULAR, Annual European Congress of Rheumatology.

Topics included cholecalciferol injections for patients with fibromyalgia, comorbidities and vitamin D, comparisons of vitamin D levels in patients with ankylosing spondylitis and in the general population, and comparisons between patients with different rheumatic diseases.

Presented below are the vitamin D study summaries from the conference that readers of www.Healio.com/Rheumatology found of particular interest.

Some Sunlight May Benefit Your Health, If You’re Older
Jul 28, 2015

We all know that getting too much sun can be harmful to your health. Excessive exposure to ultraviolet radiation from the sun is a major risk factor for most skin cancers.

But if you’re an older adult, sunlight – in the right amount – may provide health benefits too, a recent study says.

Sunlight causes your body to produce vitamin D. Data is emerging that suggests sunlight — with its ability to produce vitamin D — may reduce the risk of hip fractures, high blood pressure and stroke or heart attack for older adults, the study says.

The researchers, who  reviewed information gathered from a variety of sources, call for more data to weigh the potential benefits of moderate UV radiation against potential harm specifically for older adults.

That’s because the familiar recommendations to avoid the sun are based on data from the entire population – children through older adults. The data may not take into account important distinctions for older adults, the researchers say.

Vitamin D linked to healthy immune response to HIV, study says
Jul 27, 2015

Already commonly prescribed for elderly men and women to keep their bones strong, vitamin D supplements also could be an easy and affordable way to fight serious infections like HIV, according to a recent study led by a Penn State anthropology professor.

Nina Jablonski, whose research includes skin pigmentation and vitamin D, launched the project and enlisted South African researchers and 100 young adults in Cape Town to study how levels of ultraviolet B radiation, vitamin D in the diet, genetics and skin pigment affect vitamin D in the blood. At the same time they tested whether vitamin D supplements could reverse deficiency and improve resistance to HIV. Results were published this month in the Proceedings of the National Academy of Science.

Go ahead, soak up some sun
Jul 24, 2015

Michael F. Holick

Michael F. Holick is a professor of medicine, physiology and biophysics at Boston University Medical Center.

For decades now, our sun has been reviled and demonized. The message from the medical community: Avoid direct sun exposure, or face an increased risk of skin cancer. As the American Cancer Society helpfully put it in one ad campaign: “Fry Now. Pay Later.” The American Academy of Dermatology recommends never exposing bare skin to the sun, or even a cloudy sky, without sunscreen. The Food and Drug Administration calls ultraviolet radiation a carcinogen. These messages have caused widespread paranoia about sunlight, especially among parents who religiously apply sun protection multiple times a day on their children. After TV chef Nigella Lawson was photographed covered head to ankle in a black “modesty” swimsuit at the beach, she explained that she didn’t want to get burned.

Could a daily nine minute stroll in the sun transform your health?
Jul 22, 2015

  • - Canada and the UK are countries with 'low solar intensity' 
  • - 'Our policy of sun avoidance is creating probable harm for the population'
  • - The hours either side of midday are the best time to make vitamin D
     

We all know the rules, drummed into us by cancer charities every summer: stay out of the sun in the middle of the day, slap on high-factor sunscreen and don't overdo the sunbathing.

But according to a study by U.S. scientists published last week, in countries with 'low solar intensity' - such as Canada and the UK - 'the current policy of sun avoidance is creating probable harm for the general population'.

Furthermore, the time we're meant to avoid the sun - between 11am and 3pm - is precisely when the skin can best synthesise vitamin D in our bodies, they write in the Journal of the American College of Nutrition.

Top Nutrition Researchers Challenge Conventional Wisdom With Recommendation for More Sun Exposure
Jul 21, 2015

July 20, 2015
CLEARWATER, FL—Organizations such as the World Health Organization’s International Agency for Research on Cancer, the American Cancer Society, and the Office of the U.S. Surgeon General have all made public calls for reducing ultraviolet (UV) exposure, whether from indoor UV or from the sun.  Such recommendations stem, appropriately, from efforts to reduce cancer. At the same time, the recommendations are accompanied by a brief recognition of the importance of vitamin D, also known as the “sunshine vitamin,” along with suggestions that sufficient amounts of vitamin D can be obtained solely through food and dietary supplements.

Overly restrictive sun exposure warnings pose health risk, says new study

TORONTO, July 14, 2015 /CNW/ - Following restrictive sun exposure advice in countries with low solar intensity like Canada might in fact be harmful to your health, says the co-author of a new study on sunlight and vitamin D.

The recently published study Sunlight and Vitamin D: Necessary for Public Health by Carole Baggerly and several academic researchers, examines how organizations such as World Health Organization's International Agency for Research on Cancer and the U.S. Surgeon General call for sun avoidance, but ignore the fact that cutting out sunshine will reduce vitamin D, an essential vitamin for bone health, and create probable harm for the general population.

"Humans have adapted to sun exposure over many thousands of years and derive numerous physiological benefits from UV exposure, in addition to vitamin D," said Baggerly, executive director of GrassrootsHealth and breast cancer survivor. "These benefits are in addition to those derived from vitamin D alone and cannot be replaced by vitamin D supplements and therefore sun avoidance being recommended by the US Surgeon General, the Canadian Cancer Society, the Canadian Dermatology Association and others, is unnecessarily putting Canadians at risk."

Spring Sunshine Welcomed as Canadians Vitamin D Levels Plummet

Risk increased for a number of serious diseases

WOODSTOCK, Ont. (March 19, 2015) – A new Statistics Canada report has confirmed that 12 million Canadians have vitamin D blood levels that are below what Health Canada recommends and vitamin D levels continue to drop from previous years.

Results from the 2012 to 2013 Canadian Health Measures Survey (CHMS), released December 2014, report that 35% or 12 million Canadians have vitamin D blood levels below the Health Canada guideline of 50 nmol/L. This has increased by 3% from the previous Statistics Canada report (2009-2011) of 32%. The mean average vitamin D level for Canadians age 6-79 years has also dropped by 9.9% over the last 4 years from 68 nmol/L to 61 nmol/L. “This downward trend in vitamin D blood levels is putting more Canadians at a higher risk for many cancers including colon, breast and prostate, as well as for cardiovascular disease, diabetes, multiple sclerosis, osteoporosis and other serious diseases” stated Perry Holman, Executive Director of the Vitamin D Society.

Building consensus on optimal vitamin D levels in Canada

Key disease organizations support effort to curb vitamin D deficiency

TORONTO, Ont. (November 21, 2014) - A push to develop a Canadian Vitamin D Consesus that can be used to educate Canadians on the importance of optimal vitamin D levels for health is gaining support.

Vitamin D experts from around the world attended a workshop in Toronto earlier this month with the goal of reducing vitamin D deficiency in Canada.

A number of prominent Canadian disease organizations, including the Multiple Sclerosis Society of Canada, Osteoporosis Canada, the Canadan Breast Cancer Foundation and Prostate Cancer Canada attended the November 4 workshop on vitamin D.

"It's extemely encouraging to see momentum building behind efforts to improve education among Canadians on how to ensure they are getting enough vitamin D. Together, we can help people improve their health and reduce risk to several serious diseases," said workshop chairperson Dr. Reinhold Vieth, retired director of the Bone and Mineral Laboratory at Mount Sinai Hospital and a professor at the University of Toronto in the Department of Laboratory Medicine and Pathobiolgy.
