Patients who survive the immediate aftermath of their injuries now are at greatest risk from infections – particularly the overwhelming, life-threatening immune reaction known as sepsis – or from inflammation-induced multiorgan failure. Now, a device developed by Massachusetts General Hospital (MGH) investigators that measures the movement of key immune cells may help determine which patients are at greatest risk for complications, and a novel treatment that directly addresses the cause of such complications could prevent many associated deaths. http://medicalxpress.com/news/2013-06-movement-immune-cells-patients.html Medical research Wed, 19 Jun 2013 18:38:01 EST news290885871 A mysterious new respiratory virus that originated in the Middle East spreads easily between people and appears more deadly than SARS, doctors reported Wednesday after investigating the biggest outbreak in Saudi Arabia. http://medicalxpress.com/news/2013-06-mers-virus-easily-deadlier-sars.html Diseases, Conditions, Syndromes Wed, 19 Jun 2013 18:34:38 EST news290885659 Child care is linked to fewer emotional problems and symptoms of social withdrawal among children exposed to maternal depression, according to a new study of nearly 2000 children conducted by researchers in Montreal, Canada, at the Sainte-Justine University Hospital Research Center, Université du Québec à Montréal (UQAM), and University of Montreal. http://medicalxpress.com/news/2013-06-group-based-child-linked-emotional-problems.html Psychology & Psychiatry Wed, 19 Jun 2013 18:20:51 EST news290884819 Approximately 13 million illnesses and over 110,00 hospitalizations may have been averted by the flu vaccine over the last 6 years in the U.S, according to calculations published June 19 in the open access journal PLOS ONE by Deliana Kostova and colleagues from the U.S Centers for Disease Control and Prevention. http://medicalxpress.com/news/2013-06-flu-shot-million-illnesses-hospitalizations.html Diseases, Conditions, Syndromes Wed, 19 Jun 2013 18:19:53 EST news290884675 A study of the patients who received injections of steroids contaminated with the fungus Exserohilum rostratum from the New England Compounding Center has found that some patients had fungal infections even though they did not experience a worsening of their symptoms and that magnetic resonance imaging (MRI) can help detect infection, especially among those individuals who received injections from highly contaminated lots. http://medicalxpress.com/news/2013-06-evolution-outbreak-complications-contaminated-steroid.html Diseases, Conditions, Syndromes Wed, 19 Jun 2013 18:16:35 EST news290884573 One in four people who survive a stroke or transient ischemic attack (TIA) suffer from symptoms of post-traumatic stress disorder (PTSD) within the first year post-event, and one in nine experience chronic PTSD more than a year later.

If that were the whole story, it might be possible to imagine spike codes which could then be used to estimate the flow of information, and perhaps energy, in the brain. The reality as most in the field know, is that neurons do their bidding with transmitter-charged vesicles. The principles of vesicle operation, and by implication any codes that might be involved, are entirely different from those of spikes. While much of neuroscience has concerned itself with the interaction of these two phenomena, they have yet to be satisfactorily reconciled. A recent review appearing in Trends in Neuroscience suggests that sensory systems might offer the best clues towards divining the form of what we might call, an electric potential to vesicle fusion "transfer function." In particular, the researchers examine the ribbon synapses that tend to be found wherever fast, sustained and reliable transmission may be required. By making the case that spikes and graded potentials have complementary roles in transducing sensory information into vesicle fusion, they seek to better define the costs of synaptic transmission. http://medicalxpress.com/news/2013-06-efficient-transmission-sensory-synapses.html Neuroscience Wed, 19 Jun 2013 15:30:01 EST news290872391 A team of researchers at the University of Pittsburgh has developed antibacterial compounds, derived from the outer coating of HIV, that could be potential treatments for drug-resistant bacterial infections and appear to avoid generating resistance.
