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.
Teens who were severely bullied as children at higher risk of suicidal thoughts, mental health issue
Teens who were severely bullied as children by peers are at higher risk of mental health issues, including suicidal thoughts and behaviours, according to new research in CMAJ (Canadian Medical Association Journal).
Bowel scope screening increased by more than a fifth (21.5 percent) when people were sent additional reminders with a leaflet that addressed common concerns, according to a new study funded by Cancer Research UK.
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.
Scientists compared fecal samples from surfers and non-surfers to assess whether the surfers' guts contained E. coli bacteria that were able to grow in the presence of the antibiotic cefotaxime. Cefotaxime has previously been prescribed to kill off these bacteria, but some have acquired genes that enable them to survive this treatment.The study found that 13 of 143 (9 percent) of surfers were colonized by these resistant bacteria, compared to just four of 130 (3 percent) of non-surfers swabbed.
'The beauty of this research is that someone using only a laptop and an object that flickers can detect if someone is using a drone to spy on them,' says Ben Nassi, a Ph.D. student in the BGU Department of Software and Information Systems Engineering and a researcher at the BGU Cyber Security Research Center (CSRC). 'While it has been possible to detect a drone, now someone can also tell if it is recording a video of your location or something else.'
Two patterns of antecedent or 'prodromal' psychiatric symptoms may help to identify young persons at increased risk of developing bipolar disorder (BD), according to a new analysis in the Harvard Review of Psychiatry. The journal is published by Wolters Kluwer.
Skiing and snowboarding are fun winter sports. As the popularity of these winter sports continue to rise, according to a review article published in the Jan. 1, 2018, issue of the Journal of the American Academy of Orthopaedic Surgeons, the number of skier and snowboarder injuries also continues to rise.
A new study led by University of Pennsylvania researchers provides an explanation for how Pacific midshipman fish can generate a mating call that emits continuously from their bodies for a full hour, entailing 360,000 muscle contractions.
UCLA bioengineering professor Ali Khademhosseini has led the development of a tissue-based soft robot that mimics the biomechanics of a stingray. The new technology could lead to advances in bio-inspired robotics, regenerative medicine and medical diagnostics.
Visible resistance to Executive Order 13769, commonly referred to the 'Muslim ban,' may have produced a rare shift in public opinion caused by 'an influx of information portraying the ban as being at odds with egalitarian principles of American identity and religious liberty,' said researchers Loren Collingwood of the University of California, Riverside; Nazita Lajevardi of Michigan State University; and Kassra A. R. Oskooii of the University of Delaware.
A collaboration led by scientists at Brookhaven has observed the concentration of lithium inside individual nanoparticles reverse at a certain point, instead of constantly increasing. This discovery is a major step toward improving the battery life of consumer electronics
A new study that seeks to better ascertain HIV mortality rates in Zambia could provide a model for improved national and regional surveillance approaches, and ultimately, more effective HIV treatment strategies.
A nanostructured gate dielectric may have addressed the most significant obstacle to expanding the use of organic semiconductors for thin-film transistors. The structure, composed of a fluoropolymer layer followed by a nanolaminate made from two metal oxide materials, serves as gate dielectric and protects the organic semiconductor - which had previously been vulnerable to damage from the ambient environment.
By analyzing immune cells of children who came to the emergency department with flu symptoms, researchers found that the suite of genes these early-response cells expressed was shaped by factors such as age and previous exposures to viruses. Better understanding how early infections influence long-term immune response has implications for the diagnosis and treatment of young patients who suffer from acute respiratory tract infections.
Nearly one-quarter of children and teens who had their blood pressure screened at a primary care appointment showed a reading in the hypertensive range, but less than half of those readings could be confirmed after the blood pressure was repeated, according to a new Kaiser Permanente study released today in The Journal of Clinical Hypertension. The research shows the importance of taking a second blood pressure reading for those ages 3 to 17 years when the first reading is elevated.
NOAA's JPSS-1 satellite provided a visible image of the tropical storm after it made landfall along the Pilbara Coast in the northwestern part of Western Australia.
In a feat of nanoengineering, scientists have developed a new technique to map electrical circuits in the brain far more comprehensively than ever before. Scientists worldwide could use the technique to uncover the architecture of different parts of the brain.
New research reports that hyperreactive brain networks could play a part in the hypersensitivity of fibromyalgia.
The field of immunotherapy -- the harnessing of patients' own immune systems to fend off cancer -- is revolutionizing cancer treatment today. However, clinical trials often show marked improvements in only small subsets of patients, suggesting that as-yet unidentified variations among tumors result in distinct paths of disease progression and response to therapy.
