A blog about the latest news and research in clinical medicine.
A study published in the New England Journal of Medicine has found that children who were obese were almost twice as likely to die before 55 years of age than those who were not obese. Moreover, children whose weight was in the top 25% out of nearly 5,000 kids were 2.3 times more likely to [...]... Read more »

Half of the top 50 academic medical centres in the United States have no policies on their staff ghostwriting research on the behalf of pharmaceutical companies – including UCLA and Mayo Medical School.
Medical ghostwriting is “the practice of pharmaceutical companies secretly authoring journal articles published under the byline of academic researchers.” By getting academics at [...]

Receiving a diagnosis of prostate cancer is a very stressful and upsetting event, so much so that some men go on to have a fatal heart attack or kill themselves.
Two pieces of research by the same study group, one conducted in 340,000 men in the US and the other in 170,000 men from Sweden, have [...]

A Californian population based study has found that if everyone in the US reduced their daily salt intake by 3 grams – half a teaspoon – the annual number of deaths could be slashed by up to 92,000. In addition, the number of new people who get cardiovascular disease each year could drop by [...]... Read more »

A study of nearly 9,000 Australian adults has reported that people who watched 4 hours of TV a day or more were 46% more likely to die within the next six and a half years than those who watched less than 2 hours a day. Each one hour increase in daily television viewing increased the [...]... Read more »

The links between the pharmaceutical industry and doctors are many and tangled. Drug companies are keen to schmooze doctors and, directly or not, persuade clinicians to prescribe their drug instead of a similar one by a competitor. One way that drug companies try to influence doctors is by sponsoring events, such as conferences or [...]... Read more »

The journal Archives of Internal Medicine has a several cracking research papers this week.
Low carb dieters are grumpier than those on low fat diets
First up is Brinkworth et al.’s research on the long-term psychological effects of low carbohydrate diets compared with low fat diets.
In this study, 106 overweight and obese individuals were randomly assigned to [...]... Read more »

A study published in Archives of Internal Medicine has found that almost a third of clinical trials reported in top medical journals don’t adequately report the side effects of the intervention being tested.

French food is famous around the world. From the haute cuisine espoused by cordon bleu and the Michelin Guide to weird and wonderful dishes like frogs legs, the French are passionate about cooking and what they eat.
However, a study published recently in the Journal of Nutrition has found that the diet consumed by the majority [...]... Read more »

A new study published in JAMA this week has shown that in patients with colorectal cancer, taking an aspirin a day after diagnosis reduces the risk dying from the cancer or from any cause by at least 20%. Taking aspirin before diagnosis, however, did not have any effect of prognosis.
It has been known for a [...]... Read more »

Err, well, maybe. IQ does seem to account for some of the well-documented relationship between socioeconomic status and cardiovascular risk, according to new research in European Heart Journal. Simply put, being more intelligent could be one reason why people from a high socioeconomic background are less likely to die from cardiovascular disease than those [...]... Read more »

Urgh, exams. The epic ‘true-false-no idea’ multiple choicers of my undergraduate days are not a distant enough memory for me. The whole ‘get it right, get 1 point’, ‘get it wrong, lose 1 point’ approach always seemed horrendously unfair, regardless of the statistical basis for the strategy (i.e. examiners don’t want to reward people that [...]...

OK, so it seems pretty obvious that cycling or walking to work is better for you than taking the car. New research published in Archives of Internal Medicine has clarified the beneficial effects in terms of fitness and cardiovascular health of walking or cycling to work – but they’re largely only seen in men.
This study [...]... Read more »

Junior doctors are undergoing HIV tests as part of pre-employment occupational health checks without being made aware that such testing is not mandatory, according to research published in the Journal of Medical Ethics. Many junior doctors interviewed by Lee Salkeld and colleagues held the misperception that HIV testing was compulsory and felt unable to decline the test. In [...]... Read more »

The BMJ has just published an interesting paper on the factors that determine whether family agree to donate the organs of a brain dead relative.
According to the meta-analysis by researchers at the University of Oxford, careful timing and having a transplant coordinator make the request are key factors in whether relatives consent to organ donation.

Drinking three or four alcoholic drinks a day can double the risk of developing essential tremor - or ‘the shakes’ - in old age, suggest new findings from a Spanish research group. In a report published earlier this year, the same researchers found that individuals with essential tremor were four times more likely to develop [...]... Read more »

New research has shown that the side effects of tricyclic antidepressants reported by patients with functional gastrointestinal disorders (FGDs) such as irritable bowel syndrome (IBS) often aren’t actually real side effects of the drugs. Instead, most of the symptoms experienced by the women in the study were present before they started taking the medication, [...]... Read more »

BMC Medical Education has just published an interesting study that examined the incidence of fainting among medical students observing surgery. Apparently, more than 1 in 10 medical students almost or completely pass out in the operating theatre.

Results from a huge study published in Archives of Internal Medicine have shown that consumption of a high level of red and processed meat is associated with a raised risk of early death.
Men who ate the most red meat - roughly equivalent to a quarter pounder burger a day - were 31% more likely to [...]... Read more »

You’d think people with strong religious beliefs - which generally include belief in an afterlife - would be less perturbed about slipping of this mortal coil than the rest of us.
A new study published in the Journal of the American Medical Association, however, has found that cancer patients who rely on their religion for comfort during their final days are in fact almost three times more likely to use life-prolonging treatments than are less religious patients....
