Aggressive treatment for early stage bladder does not improve survival

Despite enduring more invasive tests and medical procedures, patients who were treated aggressively for early stage bladder cancer had no better survival than patients who were treated less aggressively.

Rogue Alzheimer's gene causes early brain changes

British scientists have found that some young adults who carry a certain genetic variant have an increased risk of developing Alzheimer's disease and distinct brain patterns and changes in their brain activity started decades before any symptoms appeared.

Young adults at future risk of Alzheimer's have different brain activity

Young adults with a genetic variant that raises their risk of developing Alzheimer's Disease show changes in their brain activity decades before any symptoms might arise, according to a new brain imaging study by scientists from the University of Oxford and Imperial College London.

Simple bedside test improves diagnosis of chronic back pain, could guide treatment

A simple and inexpensive method of assessing pain, developed by Massachusetts General Hospital (MGH) researchers, is better than currently used techniques for distinguishing neuropathic pain - pain caused by damage to the nervous system - from other types of chronic back pain.

New type of probe enables visualization of single ribonucleic acid

Biomedical engineers have developed a new type of probe that allows them to visualize single ribonucleic acid (RNA) molecules within live cells more easily than existing methods.

New standardized tool for the assessment of chronic pain helps distinguish pain subtypes

Joachim Scholz from Massachusetts General Hospital in Boston, USA and his colleagues studied the symptoms and signs of patients with peripheral neuropathic pain (nerve pain such as sciatica) and non-neuropathic (non-nerve) low back pain to identify the best clinical questions and physical tests for diagnosing pain types.

Schizophrenics appear to rely considerably less on top-down processing during perception

Patients with schizophrenia are able to correctly see through an illusion known as the 'hollow mask' illusion, probably because their brain disconnects 'what the eyes see' from what 'the brain thinks it is seeing', according to a joint UK and German study published in the journal NeuroImage.

Brain scan-assisted diagnosis for post-traumatic stress disorder a step closer to reality

Florence, Italy: Preliminary research examining the difference in brain activity between soldiers with post-traumatic stress disorder and those without it moves scientists a step closer to the possibility of being able one day to use brain scans to help diagnose the condition.

Fluorescent anesthetic compound brings new avenues for drug discovery

A collaboration of University of Pennsylvania and University of Wisconsin chemists and anesthesiologists have identified a fluorescent anesthetic compound that will assist researchers in obtaining more precise information about how anesthetics work in the body and will provide a means to more rapidly test new anesthetic compounds in the search for safer and more effective drugs.

What drives brain changes in macular degeneration?

In macular degeneration, the most common form of adult blindness, patients progressively lose vision in the center of their visual field, thereby depriving the corresponding part of the visual cortex of input.

New streamlined triage system for "brain attack"

Taking a page out of the playbook developed by cardiologists nearly two decades ago to promote the warning signs and swift treatment for heart attacks, a multidisciplinary team of stroke experts at the University of Rochester Medical Center (URMC) have created a new streamlined triage system at Strong Memorial Hospital's Emergency Department (ED) to provide rapid evaluation and specialized treatments to "brain attack," or stroke, patients.

Accurate assessment of heart disease leads to earlier, more aggressive therapy

In a study comparing the ability of various medical techniques to accurately determine the extent of heart disease and stratify patients according to disease severity, researchers found that myocardial perfusion testing with gated single photon emission computed tomography (gated SPECT) was a more accurate predictor of prognosis in chronic ischemic heart disease (IHD)-a painful condition caused by a temporary reduction of oxygen-rich blood to the heart.
