Artec EVA 3D scanner can detect post-op body shape changes

Utilising the Artec EVA three-dimensional (3D) mobile imaging scanner can provide an objective and reproducible source for the detection of body shape changes after bariatric surgery, according to researchers from RWTH Aachen University Hospital, Aachen, Germany, who recommended its use when evaluating central obesity, especially for research issues and body imaging before and after bariatric surgery.

Consumed soybean oil causes genetic changes in the brain

A study by researchers at UC Riverside shows that soybean oil not only leads to obesity and diabetes, but could also affect neurological conditions like autism, Alzheimer's disease, anxiety and depression. Used for fast food frying, added to packaged foods, and fed to livestock, soybean oil is by far the most widely produced and consumed edible oil in the US (Figure 1), according to the U.S. Department of Agriculture. In all likelihood, it is not healthy for humans.

Obesity, heart disease, and diabetes may be communicable diseases

Non-communicable diseases such as heart disease, cancer and lung disease are the most common causes of death, accounting for 70 percent of deaths worldwide, and are considered ‘non-communicable’ because they are thought to be caused by a combination of genetic, lifestyle and environmental factors and cannot be transmitted between people.

Dopamine and biological clock linked to obesity

The pleasure centre of the brain that produces the chemical dopamine, and the brain's separate biological clock that regulates daily physiological rhythms, are linked, and high-calorie foods that bring pleasure disrupt normal feeding schedules, resulting in overconsumption, according to researchers from the University of Virginia.

Metabolic syndrome associated with increased risk of VTE

People with metabolic syndrome are more likely to experience recurrent venous thromboembolism (VTE), according to researchers from Indiana University School of Medicine's Department of Emergency Medicine. Patients diagnosed with deep vein thrombosis (DVT) who also had markers of metabolic syndrome were more likely to experience another VTE event – and as the number of metabolic syndrome conditions that the patients exhibited increased, so too did their likelihood of experiencing VTE recurrence.

Reducing tongue fat factor reducing severity of OSA

Researchers from the Perelman School of Medicine at the University of Pennsylvania have discovered that improvements in sleep apnoea symptoms appear to be linked to the reduction of fat in the tongue. Using magnetic resonance imaging (MRI) to measure the effect of weight loss on the upper airway in obese patients, researchers found that reducing tongue fat is a primary factor in lessening the severity of OSA.

BMI better at predicting future obesity than genetics

Researchers from Michigan Medicine Frankel Cardiovascular Center (CVC) and the Massachusetts General Hospital Cardiovascular Research Center indicates that people would be better off focusing on BMI rather than genetics in predicting future obesity. The study, published in JAMA Cardiology, found that a person's BMI measurement from 25 years ago was a better predictor of their current BMI than a polygenic risk score.

Australia's obesity epidemic increasing risk of heart disease

Researchers from The University of Western Australia and the Royal Perth Hospital Medical Research Foundation are warning that Australia's obesity epidemic is undermining expert attempts to reduce cardiovascular disease. Cardiovascular disease is the leading cause of death worldwide, and affect six million Australians and  is directly linked to 27 percent of deaths in Australia each year. Almost a third of Australians currently have high blood pressure, but only half of them are aware of it.

Blood lipid profile can predict risk of T2DM better than obesity

Using lipidomics, a technique that measures the composition of blood lipids at a molecular level, and machine learning, researchers at Lund University, Sweden, have identified a blood lipid profile that improves the possibility to assess, several years in advance, the risk of developing type 2 diabetes. The blood lipid profile can also be linked to a certain diet and degree of physical activity.

Obesity may affect nearly 70% of routine blood tests in children

Weight may affect doctors' ability to correctly interpret routine blood tests in children, according to researchers from The Hospital for Sick Children and The University of Toronto in Ontario, Canada.
