Obesity contributes to cardiovascular risk no matter where a person carries the weight, concluded researchers after looking at outcomes for nearly a quarter-million people worldwide.
Body mass index, (BMI) waist circumference, and waist-to-hip ratio do not predict cardiovascular disease risk any better when physicians recorded systolic blood pressure, history of diabetes and cholesterol levels, researchers reported in The Lancet.
The research group used individual records from 58 prospective studies with at least one year of follow up. In each study, participants were not selected on the basis of having previous vascular disease. Each study provided baseline for weight, height, and waist and hip circumference. Cause-specific mortality or vascular morbidity were recorded according to well defined criteria.
Individual records included 221,934 people in 17 countries. In people with BMI of 20 kg/m2 or higher, hazard ratios for cardiovascular disease were 1.23 (95 percent CI, 1.17 to 1.29) with BMI, 1.27 (95 percent CI, 1.20 to 1.33) with waist circumference, and 1.25 (95 percent CI, 1.19 to 1.31) with waist-to-hip ratio, after adjustment for age, sex, and smoking status. After adjusting for baseline systolic blood pressure, history of diabetes, and total and HDL cholesterol, corresponding hazard rations were 1.07 (95 percent CI, 1.03 to 1.11) with BMI, 1.10 (95 percent CI, 1.05 to 1.14) with waist circumference, and 1.12 (95 percent CI, 1.08 to 1.15) with waist-to-hip ratio.
BMI, waist circumference, or waist-to-hip ratio did not importantly improve risk discrimination or predicted 10-year risk, and the findings remained the same when adiposity — the carrying of adipose tissue (fat) — measures were considered. Read more »

Cavernous angiomas belong to a group of intracranial vascular malformations that are developmental malformations of the vascular bed. These congenital abnormal vascular connections frequently enlarge over time. The lesions can occur on a familial basis. Patients may be asymptomatic, although they often present with headaches, seizures, or small parenchymal hemorrhages.
In most patients, cavernous angiomas are solitary and asymptomatic. In recent times, increasing MRI has detected several such asymptomatic cases and has prompted a study into the genetics and natural history of this condition.
It is now known that cavernous angiomas have a genetic basis. Familial forms of cavernous angiomas are associated with a set of genes called CCM genes (cerebral cavernous angioma). This is a case report describing the phenotypic expression of a familial form of cavernous angioma.
CASE REPORT
A 54-year-old man was referred for an MRI of the brain with complaints of headache and seizures. A cranial CT scan revealed few hyperdense lesions. A subsequent cranial MRI scan revealed several lesions with features representing cavernous angiomas.
The patient was offered counseling and was treated conservatively. Genetic testing was not possible due to the high prohibitive cost. However, screening of the family members by MRI was recommended.
Cranial MRI of the immediate family members was performed. Four brothers of the patient and his mother were found to have multiple cavernous angiomas. The father, youngest brother, and his younger sister were found not to have any such lesion. Both children of the patient were also found to be free of these lesions. Incidentally, a meningioma was found in the father of the patient. Read more »

I’ve recently come across a great guide about using social media in science. I cover this issue in my university course, Internet in Medicine, and I’ll definitely update my materials with these suggestions. From the Research Information Network:
This guide has been produced by the [University of Derby] International Centre for Guidance Studies (iCeGS), and aims to provide the information needed to make an informed decision about using social media and select from the vast range of tools that are available.
One of the most important things that researchers do is to find, use and disseminate information, and social media offers a range of tools which can facilitate this. The guide discusses the use of social media for research and academic purposes and will not be examining the many other uses that social media is put to across society.

Gardiner Harris had a [recent] article in the New York Times called “Talk Doesn’t Pay So Psychiatrists Turn to Drug Therapy.” The article is a twist on an old Shrink Rap topic, “Why your Shrink Doesn’t Take Your Insurance.” Only in this article the shrink does take your insurance, he just doesn’t talk to you.
With his life and second marriage falling apart, a man said he needed help. But the psychiatrist, Dr. Donald Levin, stopped him and said: “Hold it. I’m not your therapist. I could adjust your medications, but I don’t think that’s appropriate.”
Dr. Levin sees 40 patients a day. And he’ss 68 years old. This guy is amazing. There’s no way I could see 40 patients a day for even one day. He’s worried about his retirement, but I wouldn’t make it to retirement at that pace. (Should we make a bet on whether Dr. Levin has a blog?)
The article has a whimsical, oh-but-for-the-good-old-days tone. In-and-out psychiatry based on prescribing medications for psychiatric disorders is bad, but the article doesn’t say why. In the vignettes, the patients get better and they like the psychiatrist. Maybe medications work and psychotherapy was overemphasized in the days of old? The patients don’t complain of being short-changed, and if Dr. Levin can get 40 patients a day better for — your guess is as good as mine, but let’s say — $60 a pop, and they only have to come every one to three months, and there’s a shortage of psychiatrists, then what’s the problem? Why in the world would anyone pay to have regular psychotherapy sessions? Read more »

The number of cancer survivors in the United States increased to 11.7 million in 2007, according to a report released by the Centers for Disease Control and Prevention (CDC) and the National Cancer Institute (NCI), part of the National Institutes of Health (NIH). Women survive more often, and survive longer, according to the report.
There were 3 million cancer survivors in 1971 and 9.8 million in 2001. Researchers attributed longer survival to a growing aging population, early detection, improved diagnostic methods, more effective treatment and improved clinical follow-up after treatment.
The study, “Cancer Survivors in the United States, 2007,” is published today in the CDC’s Morbidity and Mortality Weekly Report.
To determine the number of survivors, the authors analyzed the number of new cases and follow-up data from NCI’s Surveillance, Epidemiology and End Results Program between 1971 and 2007. Population data from the 2006 and 2007 Census were also included. The researchers estimated the number of persons ever diagnosed with cancer (other than non-melanoma skin cancer) who were alive on Jan. 1, 2007. Read more »
