Research: Being overweight may be linked to longevity
In a review of 97 previous studies covering almost 3 million people, researchers found that being overweight or slightly obese was linked to an approximate 6% lower risk of dying as compared to those of normal weight. However, severe obesity was found to be tied to an almost 30% higher mortality rate. This “obesity paradox” research has several variables to be considered and should not be used as permission to gain weight.
MRIs indicate brain injuries not seen by CT scans
According to a new clinical trial, MRIs may be favorable at predicting long-term outcomes for individuals with mild, traumatic brain injuries as compared to CT scans. All 135 patients in the trial received CT scans and then MRIs roughly a week later. Most of the patients (99) had no detectable injury on the CT scan; however, over a quarter (27 out of 99) that had “normal” CT scans had focal lesions on their MRI, which are signs of microscopic bleeding in the brain.
Cancer drug substitute leads to higher relapse rate
Abby Alonzo was 10 when she was diagnosed with Hodgkin’s lymphoma in 2009. Proper treatment of this disease leads to a 90% patient survival rate. In 2010, 23 cancer drugs had shortages (including mechlorethamine), and patients like Abby had to settle for the next best thing – a drug known as cyclophosphamide. New studies have shown that 88% of those treated with the original drug were cancer-free after two years, while only 75% were cured with the substitute.
Obesity declining among youth in low-income areas
A new study conducted by the Center for Disease Control and Prevention (CDCP) found that obesity rates have declined among two- to four-year-olds in poor families across the U.S. The results showed that obesity within this demographic fell from 15.2% (2003) to 14.9 (2010). The findings were based on polling data from 30 states, spanning from 1998 to 2010.
