Universal health care systems such as Canadas exist, to a very large extent, because access to health care is considered a fundamental right of everyone, irrespective of income and social status. While there is good evidence that access to acute medical care such as cardiac surgery is equitably distributed across income groups, there is little evidence regarding access to the expanding array of diagnostic imaging procedures such as CT scans and MRIs.
In this study, investigators looked at over 300,000 imaging procedures in Winnipeg over a 1 year period. Unexpectedly, rates of diagnostic imaging were almost always higher in the highest income groups. Compared with patients in the lowest-income categories, patients in the highest-income groups were much more likely to receive general radiology, ultrasound, MRIs and CTs.
The relative higher frequencies of access to these procedures among higher-income individuals held for all age groups and for all but a few procedures. Only for obstetric ultrasound were rates of use for women in the lowest-income group higher than those for women in the highest-income group. All of these comparisons took into account the patients level of illness (morbidity). The differences in rates of utilization varied, but of 36 analyses, 21 were significant; in 8 of the significant analyses, utilization rates were more than twice as high in the highest-income groups, and these tended to occur in patient groups who were most ill.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
