Adiposity linked to cognitive decline in elderly

High levels of adiposity increase rates of cognitive decline in the “young elderly” aged between 60 and 70 years, report Korean researchers.

Early CT ‘definitive’ for subarachnoid hemorrhage diagnosis

Cerebrospinal fluid analysis is only necessary for patients with thunderclap headache and a negative computed tomography scan if they undergo imaging more than 6 hours after headache onset, research suggests.

SPECT/CT with 99mTc-HMPAO-WBC can improve diagnosis of infectious endocarditis

When combined with standard diagnostic tests, functional imaging procedures have been shown to reduce the rate of misdiagnosed cases of infectious endocarditis. According to new research published in the August issue of The Journal of Nuclear Medicine, single photon emission computed tomography (SPECT)/computed tomography (CT) with 99mTc-hexamethylpropleneamine oxime-labeled white blood cells (99mTc-HMPAO-WBC) can improve the diagnosis of infectious endocarditis in hard-to-diagnose cases.

Insight into neural basis of human consciousness

Which areas of the brain help us to perceive our world in a self-reflective manner is difficult to measure. During wakefulness, we are always conscious of ourselves. In sleep, however, we are not. But there are people, known as lucid dreamers, who can become aware of dreaming during sleep. Studies employing magnetic resonance tomography (MRT) have now been able to demonstrate that a specific cortical network consisting of the right dorsolateral prefrontal cortex, the frontopolar regions and the precuneus is activated when this lucid consciousness is attained.

Short-course palliative RT shows promise

A 2-day course of three-dimensional radiotherapy delivered in twice-daily fractions up to 18 Gy resulted in no dose-limiting toxicities, and high rates of symptom relief in patient with pelvic cancer, especially those with bleeding, report researchers.

Human brown fat may actually be beige

Beige fat cells are more closely related to white than brown fat cells, say researchers who found that brown fat deposits in humans appear to be composed of beige cells.

NSCLC survival increase 'an artifact of PET assessment'

There has been no increase in survival among non-small-cell lung cancer patients in recent years, with evidence suggesting otherwise likely due to positron emission tomography-induced stage migration and selection bias, say US scientists.

Study confirms safety and feasibility of optical coherence tomography in carotid arteries

Our ability to see inside the arteries of vascular disease patients in stunning high resolution before and during stenting procedures can offer a wealth of valuable information. A new study of optical coherence tomography (OCT) confirms the safety and feasibility of this imaging technique in the carotid arteries.

Pulsed-dye laser tool improves appearance, texture and elasticity of burn scars

In a collaboration among researchers at the University of Cincinnati (UC), Shriners Hospitals for Children-Cincinnati and Cincinnati Children's Hospital Medical Center, burn and skin specialists have shown that use of a pulsed-dye laser tool improves the appearance, texture and elasticity of burn scars.

Femoroacetabular hip impingement behind sports hernia

A large proportion of athletes with sports hernias also have femoroacetabular impingement of the hip on the same side of the body, results of a magnetic resonance imaging study show.

Axial length may affect macular disease evaluation

Korean researchers report that thinner macular retinal thickness, lower macular volume, and greater foveal thickness are associated with longer axial length in young individuals with myopic eyes.
