If you drink alcohol of any type, limit your intake. Not drinking alcohol is better for cancer prevention.
7. Avoid too much sun, especially for children. Use sun protection. Do not use sunbeds.
8. In the workplace, protect yourself against cancer-causing substances by following health and safety instructions.
9. Find out if you are exposed to radiation from naturally high radon levels in your home. Take action to reduce radon levels.
10. For women: Breastfeeding reduces the mother’s cancer risk. If you can, breastfeed your baby. Hormone replacement therapy (HRT) increases the risk of certain cancers. Limit use of HRT. 11. Ensure your children take part in vaccination programmes for:
Hepatitis B (for newborns) Human papillomavirus (HPV) (for girls) 12. Take part in organised cancer screening programmes for:
Bowel cancer (men and women) Breast cancer (women) Cervical cancer (women)
Apple announced its watchOS 2 on September 9. One of the major selling points behind the Apple Watch has always been combining the smartwatch idea alongside health and fitness tracking. Is this selling point panning out? What technological trends are seen in the healthcare industry and mobile devices — and are they really making a difference for doctors and patients? Amidst the buzz, here is a sampling of some Apple Watch apps that actually might be revolutionizing the healthcare industry.

Those of you who know me know that I’m a video game nerd. And comic book nerd. And just nerdy nerd in general. So when I read an article that used World of Warcraft to model disease outbreaks, I jumped … Continue reading »
If you ever read public health research, you’ve probably encountered the term “Student’s t-test,” or just “t-test.” The experimenters will do this magical test, and suddenly conclude that everything is awesome. But even when you’re familiar with the t-test and … Continue reading »
This post originally appeared on Mr Epidemiology on 16 April 2012. The negative health effects of sedentary behaviour are a hot topic gaining scientific and popular attention. News outlets have emphasised that sitting is killing us. Given the tsunami-like obesity epidemic that has … Continue reading »
Back in March 2013, Research2Guidance counted in the neighborhood of 100,000 health, fitness and wellness apps in the Apple App Store and Google Play. That number almost certainly has increased since then.
Today, consumer health engagement company HealthMine said that while 64 percent of Americans own smartphones, just 18 percent of the general population enjoy learning health, wellness and lifestyle information via mobile apps. That’s based on a survey of 1,200 people by the Dallas-based company.
And then comes the money quote from the HealthMine press release: “Mobile health is still far from broad engagement—unless you are sick.” That’s because another HealthMine survey of 509 people with diabetes or pre-diabetes from August found that 42 percent manage their condition with mobile blood-sugar monitors, while 39 percent use mobile monitors for blood pressure.

How retroviruses like HIV spread in their hosts had been unknown — until a Yale team devised a way to watch it actually happen in a living organism. The elaborate and sometimes surprising steps the virus takes to reach and spread in the lymph nodes of a mouse have been captured on videos and described in the Oct. 2 issue of the journal Science.
“It’s all very different than what people thought,” said Walther Mothes, associate professor of microbial pathogenesis and co-senior author the paper.
Tracking fluorescently stained viruses in mice, the Yale team led by Mothes and co-senior author Priti Kumar, assistant professor of medicine and microbial pathogenesis, used sophisticated imaging technology to capture the action as the viral particles bind to macrophages via a sticky protein that is located at the capsule of the lymph node.
But that is only the first step of the journey. The captured viral particles open to a rare type of B-cell, seen in red in the accompanying movie. The virus particles then attach themselves to the tail of these B-cells and are dragged into the interior of the lymph node. In one to two days, these B-cells establish stable connections with tissue, enabling full transmission of the virus.
The insights provided by the videos identify a potential way to prevent HIV from infecting surrounding tissue. If researchers could develop a way to block the action of the sticky protein the virus uses to bind to macrophages, then the virus’ transmission could be halted, Mothes suggested.
