Food insecurity, meaning inadequate or insecure access to food because of a lack of money, has worsened in Nunavut communities since the introduction of the federal government's Nutrition North Canada program in 2011, found research published in CMAJ (Canadian Medical Association Journal).
Even before the introduction of Nutrition North Canada, food insecurity was a widespread problem in Nunavut communities, with some of the highest rates of food insecurity in Canada.
A team of economists has concluded that soda taxes serve as a "net good," an assessment based on an analysis of health benefits and consumer behavior. The work, which sees advantages similar to those of long-standing cigarette taxes, also offers policy parameters that it views as more effective than many existing soda taxes.
The analysis, by researchers at New York University, the Wharton School at the University of Pennsylvania, and the University of California, Berkeley, was released today as a National Bureau of Economic Research (NBER) working paper.
Results from a study published early online in CANCER, a peer-reviewed journal of the American Cancer Society, point to the need for improved access to medical care for sexual minority cancer survivors, in particular female survivors. In female cancer survivors, poor access to care is more strongly related to poor quality of life among sexual minorities compared with heterosexuals.
Your smile, and associated oral health, may be a factor for successfully passing through the revolving doors of life. It is your first impression to a stranger, the closing argument to land a job and a major factor to achieving a good quality of life. For those who struggle with substance use disorder, oral health often falls off the precipice of self-care thereby seriously damaging interpersonal skills, while causing poor nutrition, increased oral and general infections and debilitating oral pain.
A new laboratory-based method of estimating outcomes for patients with a severe pulmonary disorder that has no cure can help physicians better provide proper care, referrals, and services for patients at the end of life, according to a new study of more than 17,000 patients from Intermountain Healthcare.
After 20 years of rapid increases in life expectancy at birth, the rate of growth in Australia is now falling behind most other high-income nations, meaning better control of health risk factors such as obesity will be needed if further life expectancy increases are to be achieved, research shows.
Published today by the Medical Journal of Australia, researchers from the University of Melbourne School of Population and Global Health have analysed data for Australia and 26 other high-income countries from 1980-2016.
A study of nearly 300 patients with mild persistent asthma found that inhaled steroids--long considered the gold standard for asthma treatment--were no more effective than placebo in nearly three-fourths of the study patients, all over age 12. Inhaled steroids were better than placebo for a subset of the patients who had high levels of a particular type of inflammatory cells, called eosinophils, in their sputum, but they represented about a fourth of patients enrolled in the trial.
ATS 2019, Dallas, TX -- In addition to suppressing tumors, the protein tuberous sclerosis complex 2 (TSC2) may play a role in preventing or treating pulmonary arterial hypertension (PAH), according to research presented at ATS 2019. Researchers found that a deficiency of this protein produced dysfunctional molecules unable to support cell structure and function, resulted in thickening of pulmonary blood vessels and led to PAH.
PITTSBURGH, May 19, 2019 - Reversibly paralyzing and heavily sedating hospitalized patients with severe breathing problems do not improve outcomes in most cases, according to a National Institutes of Health-sponsored clinical trial conducted at dozens of North American hospitals and led by clinician-scientists at the University of Pittsburgh and University of Colorado schools of medicine.
San Diego, CA (May 18, 2019) -- Damage to the lining of the stomach can occur quickly when children swallow button batteries; therefore, clinicians should consider prompt endoscopic removal, even when the child is symptom free and the battery has passed safely through the narrow esophagus, according to research presented at Digestive Disease Week® (DDW) 2019. The recommendations represent a change from current practice of watching and waiting.
Many men continue to abuse steroids despite knowing that they have serious, life-limiting and potentially lethal side effects, according to findings to be presented in Lyon, at the European Society of Endocrinology annual meeting, ECE 2019. The study findings indicate that men using anabolic steroids to improve strength and physical performance are often aware of the side effects but choose to continue taking them.
Gastric cancer, Q fever, Legionnaires' disease, whooping cough--though the infectious bacteria that cause these dangerous diseases are each different, they all utilize the same molecular machinery to infect human cells. Bacteria use this machinery, called a Type IV secretion system (T4SS), to inject toxic molecules into cells and also to spread genes for antibiotic resistance to fellow bacteria. Now, researchers at Caltech have revealed the 3D molecular architecture of the T4SS from the human pathogen Legionella pneumophila with unprecedented details.
UPTON, NY--From the ancient pyramids to modern buildings, various three-dimensional (3-D) structures have been formed by packing shaped objects together. At the macroscale, the shape of objects is fixed and thus dictates how they can be arranged. For example, bricks attached by mortar retain their elongated rectangular shape. But at the nanoscale, the shape of objects can be modified to some extent when they are coated with organic molecules, such as polymers, surfactants (surface-active agents), and DNA.
May 13, New Delhi: Children born to teenage mothers are more likely to be undernourished than children of adult mothers. A new study, the first to comprehensively examine links between teenage pregnancy and child undernutrition in India, by researchers at the International Food Policy Research Institute (IFPRI) helps to understand how this happens.
The rate of bowel cancer--otherwise known as colorectal cancer or CRC--is rising among adults aged 20-49 in Europe, suggests research published online in the journal Gut today.
Rates rose most steeply among the youngest age group (20-29 years), and the authors warn that if the trend continues, screening guidelines may need to be reconsidered.
Rates tend to be lower among people over 50, but the opposite is true among younger adults in North America, Australia and China, say the researchers.
