BOSTON - Prostate tumors tend to be what scientists call "indolent" - so slow-growing and self-contained that many affected men die with prostate cancer, not of it. But for the percentage of men whose prostate tumors metastasize, the disease is invariably fatal.
Researchers have shown for the first time how children can inherit a severe - potentially fatal - mitochondrial disease from a healthy mother. The study, led by researchers from the MRC Mitochondrial Biology Unit at the University of Cambridge, reveals that healthy people harbour mutations in their mitochondrial DNA and explains how cases of severe mitochondrial disease can appear unexpectedly in previously unaffected families.
The common practice of using patient self-report screening questionnaires rather than diagnostic interviews conducted by researchers has resulted in overestimates of the prevalence of depression, according to an analysis in CMAJ (Canadian Medical Association Journal) http://www.cmaj.ca/lookup/doi/10.1503/cmaj.170691.
To help address the opioid overdose epidemic, Canada should develop a regulated program to distribute opioids and prevent deaths, argues a commentary in CMAJ (Canadian Medical Association Journal) http://www.cmaj.ca/lookup/doi/10.1503/cmaj.171060
Pediatric rheumatic diseases are a varied group of rare diseases including juvenile forms of arthritis, lupus, fibromyalgia, and other conditions. Currently, there is considerable variability in how patients with these diseases are treated in clinical practice, making it difficult to understand which therapies work best. A new review article in Arthritis & Rheumatology examines recent efforts to address this challenge.
Woods Hole, Mass.-- Many of the genes involved in natural repair of the injured spinal cord of the lamprey are also active in the repair of the peripheral nervous system in mammals, according to a study by a collaborative group of scientists at the Marine Biological Laboratory (MBL) and other institutions. This is consistent with the possibility that in the long term, the same or similar genes may be harnessed to improve spinal cord injury treatments.
MANHASSET, NY - Northwell Health's Feinstein Institute for Medical Research Associate Professor Ona E. Bloom, PhD, along with colleagues at the Marine Biological Laboratory (MBL), published today in Scientific Reports that many of the genes that repair an injured spinal cord in a fish called the lamprey are also active in the repair of the peripheral nervous system in mammals.
The team lead by Sílvia Vilares Conde, from CEDOC-NOVA Medical School, in collaboration with the pharmaceutical company Galvani Bioelectronics, demonstrated through findings in rats that is possible to restore insulin sensitivity and glucose homeostasis, by modulating electrically the carotid sinus nerve, the sensitive nerve that connects the carotid body with the brain. The study is published in Diabetologia, the journal of the European Association for the Study of Diabetes [EASD].
Bowel scope screening uptake increased by more than a fifth (21.5%) when people were sent additional reminders with a leaflet that addressed common concerns, according to a new study funded by Cancer Research UK.*
Regular surfers and bodyboarders are three times more likely to have antibiotic resistant E. coli in their guts than non-surfers, new research has revealed.
Conducted by the University of Exeter, the Beach Bums study asked 300 people, half of whom regularly surf the UK's coastline, to take rectal swabs. Surfers swallow ten times more sea water than sea swimmers, and scientists wanted to find out if that made them more vulnerable to bacteria that pollute seawater, and whether those bacteria are resistant to an antibiotic.
