Scientist develop mathematical model that predicts how individuals respond to cancer treatment

Vittorio Cristini, PhD, uses the example of an airplane to explain what he does in cancer research. "Before calculus," he says, "people couldn't really design a plane that would fly. You can do it by trial and error, but it would probably take centuries." Dr. Cristini has a faster way to try to understand cancer treatment. Like airplane designers today, he uses a mathematical model.

Dopamine responses to alcohol ingestion may serve as marker of vulnerability to AUDs

There are two traits closely associated with the development of alcohol use disorders (AUDs). One is a lower subjective intoxication response, also known as a low level of response to alcohol.

Observation time in ER is associated with reduced CT rates for children at risk of TBI

The longer a child with minor blunt head trauma is observed in the emergency department, the less likely the child is to require computed tomography (CT) scan, according to the results of a study published online Friday in Annals of Emergency Medicine ("Impact of the Duration of Emergency Department Observation on Computed Tomography Use in Children with Minor Blunt Head Trauma").

Task force recommends annual CT scans for high-risk smokers

The U.S. Preventive Services Task Force has recommended that high-risk current and former smokers get an annual CT Scan to look for cancer. If the draft recommendation becomes final, insurers will likely have to cover the scan at no co-pay cost to consumers.

Glucose intolerance, insulin resistance not associated with pathological features of AD

Glucose intolerance or insulin resistance do not appear to be associated with pathological features of Alzheimer disease (AD) or detection of the accumulation of the brain protein β-amyloid (Αβ), according to a report published by JAMA Neurology, a JAMA Network publication.

Research roundup: Eye care disparities; more complications for Medicaid patients after spine surgery; the cost to states opting against Medicaid expansion

After analyzing 2003-2004 data of patients who underwent spinal surgery at two medical institutions, they found that Medicaid beneficiaries were at much higher risk of experiencing any type of complication than patients who are privately insured. "The results of our study further support the growing body of literature that Medicaid patients have higher rates of complications," the authors write. When evaluating patients and considering the likelihood of complications, "Medicaid status should be considered as well," they concluded (Hacquebord et al., 7/15).

MedUni Vienna cardiologist demonstrates effectiveness of substance that makes heart softer

Heart failure with concomitant pulmonary hypertension is a growing health problem with a high mortality rate, above all in older people. The cardiologist Diana Bonderman from the University Department of Internal Medicine II at the MedUni Vienna, as the author of a multinational phase II study, has demonstrated the effectiveness of a substance that sticks to the so-called nitric oxide pathway and makes the heart "softer".

Long-term cannabis use, dopamine and motivation: an interview with Dr Michael Bloomfield, Department of Medicine at Imperial

We classified ‘long-term’ cannabis use as being regular, at least weekly, cannabis use for over 12 months. This is the period of time that’s used in the DSM-IV psychiatric diagnostic manual to classify substance use disorders. In our study the average duration of at least weekly use was just over four and a half years.

Research shows that rates of coronary heart disease are higher with longer duration of obesity

In a study of adults recruited and followed up over the past 3 decades in the United States, longer duration of overall and abdominal obesity beginning in young adulthood was associated with higher rates of coronary artery calcification, a subclinical predictor of coronary heart disease, according to a study in the July 17 issue of JAMA.
