Blood-Borne Cancer Detection Receives Gold-Plated Boost
UNSW researchers have discovered a new way to detect ultralow levels of microRNA in a blood sample which could make the diagnosis of cancer and other illnesses quicker and more efficient.

Obamacare Enrollee Numbers Not Falling
Health insurance coverage rates have held steady in the United States, despite continued commotion over the future of the Affordable Care Act, a new government report shows.
General Surgeon Shortage Growing in The US
The shortage of general surgeons in the U.S. is projected to get worse as the number of these doctors entering the workforce each year fails to keep pace with population growth, a U.S. study suggests.
Hypertensive Patients Rely On Medication
Patients with high blood pressure are relying solely on medication to reduce their risk of heart attack, stroke and heart failure, rather than decreasing salt intake as instructed by their physicians, according to research presented at ESC Congress 2018.
Vascular Channels Connect Skull Bone Marrow And The Brain Surface
According to a new study of mice and humans, tiny tunnels run from skull bone marrow to the lining of the brain and may provide a direct route for immune cells responding to injuries caused by stroke and other brain disorders. Bone marrow, the spongy tissue inside most of our bones, produces red blood cells as well as immune cells that help fight off infections and heal injuries. The study was published in Nature Neuroscience.
Membrane Proteins Facilitate To Communicate Between Cells
Researchers examined the protein structures, about 30% of the proteins encoded by the human genome are membrane proteins that span the cell membrane so they can facilitate communication between cells and their environment. These molecules are critical for learning, seeing, and sensing odors, among many other functions. The study was published in the Proceedings of the National Academy of Sciences.
Microscopy Visualizes The Inner Workings Of A Living Cell
Researchers show that a widely used chemical tracer, combined with a cutting-edge microscope, can track metabolic changes within the living cells of animals. Imaging tools like X-rays and MRI have revolutionized medicine by giving doctors a close-up view of the brain and other vital organs in living, breathing people.
A new way to zoom in at the tiniest scales to track changes within individual cells. The tool combines a widely used chemical tracer, D2O, or heavy water, with a relatively new laser-imaging method called stimulated Raman scattering (SRS). The study was published in Nature Communications.
Space Changes The Body In Several Ways
Scientists conducted a study at unraveling how nature versus nurture plays out in space. As part of NASA’s Twins Study, they collected biological samples from each of the Kellys before sending Scott to the International Space Station for a year starting in March 2016.
Meanwhile, his brother Mark, who retired as an astronaut in 2011, remained on Earth to serve as the control subject. By analyzing how each twins’ biological markers evolved during the mission, the researchers learned a great deal about how the human body reacts both physically and mentally to extended periods of spaceflight.
Estimating The Rate Of Sedation-Related Adverse Events And PRO
Researchers estimated a significant proportion of moderate-to-deep sedation is performed by sedation practitioners under the indirect supervision of an anesthesiologist but there are limited safety data available. This was a prospective national observational study. Data were collected with a modified adverse event reporting tool from the International Sedation Task Force of the World Society of Intravenous Anaesthesia.
Moderate-to-deep Sedation
A total of 24 hospitals in the Netherlands where moderate-to-deep sedation was performed by sedation practitioners from the 1 February 2015 to 1 March 2016. Consecutive adults undergoing moderate-to-deep sedation for gastrointestinal, pulmonary and cardiac procedures.
Patients Need Timely Access to Palliative Care
Researchers have identified physicians’ familiarity with palliative or hospice care personnel or through their patients as key. Another critical factor, of course, is receptivity to difficult conversations and palliative approaches by the patients and families themselves. The study was published in Palliative Medicine and Health Affairs.
Bed Nets Have Greater Impact on Malaria Transmission, Researchers
A new study published in the Lancet journal EClinical Medicine suggests that more mosquito nets are likely needed between mass campaigns to keep malaria cases in check. Writing in an accompanying commentary, Johns Hopkins Center for Communication Programs' Hannah Koenker, PhD, says the paper shows that the loss of treated bed nets between mass campaigns may have a much greater impact on malaria transmission than previously understood.
Stress Gene Linked To Chronic Pain After Traumatic Injury
The gene FKBP5 is a critical regulator of the stress response and affects how we respond to environmental stimuli. Previous studies have shown that certain variants of this gene play a role in the development of neuropsychiatric disorders such as posttraumatic stress disorder, depression, suicide risk, and aggressive behavior.
The study was published in the Journal of Neuroscience, has confirmed this association in a cohort of more than 1,500 people of both European American and African American descent who experienced motor vehicle collision trauma.
