Population age and inpatient care
2012-03-20
(Press-News.org) The effect of population aging on the number of admissions to hospital for inpatient treatment is examined by epidemiologist Enno Nowossadeck in the latest issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2012; 109[9]: 151-7.
Germany's population is steadily growing older, and the number of hospital admissions is increasing. By taking nationwide statistics on hospital treatment in the years 2000 and 2009 and classifying the patients by year of birth, sex, and diagnosis, the author investigates whether these two trends are connected.
His analysis reveals, for example, that the high birthrate in the years 1934 to 1944 was responsible for a large number of admissions for treatment of colon cancer, while the low birthrate in the years immediately after World War II led to a low rate of prostate cancer in the study period.
Moreover, the probability of hospital admission for treatment of a given disease also changes with time. This can reinforce, weaken, or cancel out the influence of population aging. In the case of heart failure, for instance, the effects of aging and the increased likelihood of hospitalization resulted in much higher case numbers than would have been expected from population aging alone.

Zug, Switzerland and San Diego, CA – Cytori Therapeutics (NASDAQ: CYTX) announced today the publication of RESTORE-2 trial results in the peer-reviewed European Journal of Surgical Oncology.
RESTORE-2 is a 71 patient multi-center, prospective clinical trial using autologous adipose-derived regenerative cell (ADRC)-enriched fat grafting for reconstruction of the breast after cancer surgery. The majority of patients underwent radiation prior to the procedure, creating an unfavorable ischemic environment for which breast reconstruction with ADRC-enriched fat grafting appears ...

DURHAM, N.H. –– Space scientists from the University of New Hampshire and multi-institutional colleagues report they have quantified levels of radiation on the moon's surface from galactic cosmic ray (GCR) bombardment that over time causes chemical changes in water ice and can create complex carbon chains similar to those that help form the foundations of biological structures. In addition, the radiation process causes the lunar soil, or regolith, to darken over time, which is important in understanding the geologic history of the moon.
The scientists present their findings ...

More than 400 years after Galileo's discovery of Io, the innermost of Jupiter's largest moons, a team of scientists led by Arizona State University (ASU) has produced the first complete global geologic map of the Jovian satellite. The map, published by the U. S. Geological Survey, depicts the characteristics and relative ages of some of the most geologically unique and active volcanoes and lava flows ever documented in the Solar System.
Following its discovery by Galileo in January 1610, Io has been the focus of repeated telescopic and satellite scientific observation. ...

A new study by University of Notre Dame biologist Michael Pfrender and a team of researchers from the University of Nevada-Reno, Utah State University and the University of Virginia suggests that snakes from different regions of the world have evolved a similar, remarkable resistance to a deadly neurotoxin.
The finding, which appeared in the Proceedings of the National Academy of Sciences, greatly increases scientists' understanding of the genetic basis of adaptation and is a model for understanding the limits to adaptation and the degree to which evolutionary responses ...

"Anyone who has been admitted into a hospital or undergone a procedure, even if cared for in the most appropriate way, can feel as though they were treated like an animal or object," says Harvard University psychologist and physician Omar Sultan Haque. Health care workers enter their professions to help people; research shows that empathic, humane care improves outcomes. Yet dehumanization is endemic. The results can be disastrous: neglect of necessary treatments or prescription of excessive, painful procedures or dangerous drugs.
What are the causes and effects of dehumanization ...

University of Alberta led research may have discovered how memories are encoded in our brains.
Scientists understand memory to exist as strengthened synaptic connections among neurons. However components of synaptic membranes are relatively short-lived and frequently re-cycled while memories can last a lifetime. Based on this information, U of A physicist and lead researcher Jack Tuszynski, his graduate student Travis Craddock and University of Arizona professor Stuart Hameroff investigated the molecular mechanism of memory encoding in neurons.
The team looked into structures ...

Montreal, March 19, 2012 – Parents should think twice before brushing off their child's calls to "look at me!" A Concordia study published in the journal Child Development is the first to show that toddlers' expectations of how their parent will respond to their needs and bids for attention relate to how eager they are to collaborate and learn.
Collaboration in toddlers has been linked to the acquisition of social rules and norms later in childhood.
Understanding what contributes to more collaboration can help improve conscience development in children.

Investigators at Nationwide Children's Hospital, working with the DNA Sequencing Core Facility at the University of Utah, have developed an approach to newborn screening (NBS) for the life-threatening genetic disorder, Duchenne muscular dystrophy (DMD) and potentially other muscular dystrophies. As a model for NBS, the approach published online in January in the Annals of Neurology provides evidence that this approach could be implemented if approved by regulatory bodies at a state level or alternatively through the Secretary's Advisory Committee on Heritable Disorders ...

ALBUQUERQUE, N.M. — In a challenge to current astrophysical models of the universe, researchers at Sandia National Laboratories Z machine and the University of Rostock in Germany have found that current estimates of ice-giant planetary interiors overstate water's compressibility by as much as 30 percent.
The work was reported in the paper "Probing the Interior of the Ice Giants" in the Feb. 27 Physical Review Letters.
"Our results question science's understanding of the internal structure of these planets," said Sandia lead author Marcus Knudson, "and should require ...
