"Everyone knows Americans are fat and getting fatter, and everyone thinks they know why: more eating and less moving.
But the "big two" factors may not be the whole story. Consider this: Animals have been getting fatter too. The National Pet Obesity Survey recently reported that more than 50 percent of cats and dogs that's more than 80 million pets are overweight or obese. Pets have gotten so plump that there's now a National Pet Obesity Awareness Day. (It was Wednesday.) Lap dogs and comatose cats aren't alone in the fat animal kingdom. Animals in strictly controlled research laboratories that have enforced the same diet and lifestyle for decades are also ballooning."

In a pilot study, 14 Gulf War veterans were randomly selected from a large list of those with unexplained illness, to compare the functional integrity of the peripheral and central nervous system with a group of 13 healthy civilian control subjects using predetermined outcome measures. The controls were matched closely for age, sex, handedness, and physical activity. Outcome measures included scoring of symptoms and clinical neurological signs, quantitative sensory testing of heat, cold and vibration sensibilities, motor and sensory nerve conduction studies on upper and lower limbs, needle EMG of distal and proximal muscles and multimodality evoked potential (visual, brainstem, and somatosensory) studies. Three measurements, all related to peripheral nerve function (cold threshold (P = 0.0002), sural nerve latency (P = 0.034), and median nerve sensory action potential (P = 0.030) were abnormal in the veterans compared with the controls. There may be a dysfunction in the veterans but more studies are required to investigate the findings further and to characterise the dysfunction if confirmed.

FDA's Voice of the Patient Report on Chronic Fatigue Syndrome Reveals Disease Impact and Areas for Progress
"GRAND RAPIDS, Mich., Oct. 3, 2013 /PRNewswire-USNewswire/ -- PANDORA Org and other patient organizations say a recent report from the U.S. Food and Drug Administration (FDA) shows the agency must take further action to open up opportunities for ME/CFS drug development. Titled "The Voice of the Patient," this report is a detailed summary of an April 25 FDA Patient-Focused Drug Development meeting, the first of its kind, where patients explained the reality of Myalgic Encephalomyelitis (ME)/Chronic Fatigue Syndrome (CFS).

Highway proximity associated with cardiovascular disease risk: the influence of individual-level confounders and exposure misclassification
Environmental Health 2013, 12:84 doi:10.1186/1476-069X-12-84
Published: 3 October 2013
Elevated cardiovascular disease risk has been reported with proximity to highways or busy roadways, but proximity measures can be challenging to interpret given potential confounders and exposure error.
We conducted a cross sectional analysis of plasma levels of C-Reactive Protein (hsCRP), Interleukin-6 (IL-6), Tumor Necrosis Factor alpha receptor II (TNF-RII) and fibrinogen with distance of residence to a highway in and around Boston, Massachusetts. Distance was assigned using ortho-photo corrected parcel matching, as well as less precise approaches such as simple parcel matching and geocoding addresses to street networks. We used a combined random and convenience sample of 260 adults >40 years old. We screened a large number of individual-level variables including some infrequently collected for assessment of highway proximity, and included a subset in our final regression models. We monitored ultrafine particle (UFP) levels in the study areas to help interpret proximity measures.
Using the orthophoto corrected geocoding, in a fully adjusted model, hsCRP and IL-6 differed by distance category relative to urban background: 43% (-16%,141%) and 49% (6%,110%) increase for 0-50 m; 7% (-39%,45%) and 41% (6%,86%) for 50-150 m; 54% (-2%,142%) and 18% (-11%,57%) for 150-250 m, and 49% (-4%, 131%) and 42% (6%, 89%) for 250-450 m. There was little evidence for association for TNF-RII or fibrinogen. Ortho-photo corrected geocoding resulted in stronger associations than traditional methods which introduced differential misclassification. Restricted analysis found the effect of proximity on biomarkers was mostly downwind from the highway or upwind where there was considerable local street traffic, consistent with patterns of monitored UFP levels.
We found associations between highway proximity and both hsCRP and IL-6, with non-monotonic patterns explained partly by individual-level factors and differences between proximity and UFP concentrations. Our analyses emphasize the importance of controlling for the risk of differential exposure misclassification from geocoding error.
"Hyderabad: It is not just nitrogen oxides and particulate matter that causes pollution in the city. A new study claims to have found high levels of toxic benzene in Hyderabad's air."
Dr. Brian Moench, president of Utah Physicians for a Healthy Environment, said it's a necessary action.
"We don't have a lot of options," he said. "We can accept our air pollution is not solvable, we can stop driving all our cars, we can tell industry to shut down, or we can stop burning wood.""
