TORONTO, August 17, 2018 - Adolescent girls and young women in Mombasa, Kenya are more likely to experience higher risks of HIV and gender-based violence when they are involved with sex work venues or have sexual experiences at a young age, suggests a study co-led by St. Michael's Hospital and the University of Manitoba in Canada.
When the good and bad bacteria in our mouth become imbalanced, the bad bacteria form a biofilm (aka plaque), which can cause cavities, and if left untreated over time, can lead to cardiovascular and other inflammatory diseases like diabetes and bacterial pneumonia.
A team of researchers from the University of Illinois has recently devised a practical nanotechnology-based method for detecting and treating the harmful bacteria that cause plaque and lead to tooth decay and other detrimental conditions.
A few little cells that are different from the rest can have a big effect. For example, individual cancer cells may be resistant to a specific chemotherapy--causing a relapse in a patient who would otherwise be cured. In the journal Angewandte Chemie, scientists have now introduced a microfluidics-based chip for the manipulation and subsequent nucleic-acid analysis of individual cells. The technique uses local electric fields to highly efficiently "trap" the cells (dielectrophoresis).
BOSTON - Every year, more than 330,000 people are diagnosed with kidney cancer worldwide. More than 80 percent of those new cases are renal cell carcinomas (RCC). When caught early, the five-year survival rate is more than 90 percent. Patients diagnosed with more invasive tumors, however, have dramatically poorer prognoses, with five-year survival rates of 50 percent and 10 percent for patients diagnosed at stages III and IV respectively. Early detection could improve the overall survival rate in patients at high risk for death from RCC.
GALVESTON, Texas - A new study from The University of Texas Medical Branch at Galveston has uncovered why some people that have brain markers of Alzheimer's never develop the classic dementia that others do. The study is now available in the Journal of Alzheimer's Disease.

-- Low-carb diets that replace carbohydrates with proteins and fats from plant sources associated with lower risk of mortality compared to those that replace carbohydrates with proteins and fat from animal sources.
Eating carbohydrates in moderation seems to be optimal for health and longevity, suggests new research published in The Lancet Public Health journal.
A blood test conducted as early as the 10th week of pregnancy may help identify women at risk for gestational diabetes, a pregnancy-related condition that poses potentially serious health risks for mothers and infants, according to researchers at the National Institutes of Health and other institutions. The study appears in Scientific Reports.
Fragility fractures are a serious yet neglected complication of both type 1 and type 2 diabetes, with increased risk of fragility fractures in people with diabetes extending across the life span.
This is a concern as, globally, the prevalence of diabetes in adults is expected to increase from almost 425 million today, to approximately 629 million by 2045. At the same time, many clinicians who treat patients with diabetes are not aware of their patients' heightened risk of disabling and potentially life-threatening fractures.
MINNEAPOLIS - The eyes may be a window to the brain for people with early Parkinson's disease. People with the disease gradually lose brain cells that produce dopamine, a substance that helps control movement. Now a new study has found that the thinning of the retina, the lining of nerve cells in the back of the eye, is linked to the loss of such brain cells. The study is published in the August 15, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology.
The ongoing opioid epidemic in the United States is a key contributor to the most recent declines in life expectancy, suggests a study published by The BMJ today.
A second study shows an increase in US death rates in midlife (people aged between 25-64 years) involving all major racial groups, and cites a broad range of conditions as potential causes.
Together, these findings point to an urgent need to examine systemic causes of declining health in the US.
