Death highest in heart failure patients admitted in January, on Friday, and overnight

Data from nearly 1 million patients over 14 years

2013-05-25

(Press-News.org) Lisbon, 25 May 2013: Mortality and length of stay are highest in heart failure patients admitted in January, on Friday, and overnight, according to research presented today at the Heart Failure Congress 2013. The analysis of nearly 1 million heart failure admissions over 14 years was presented by Dr David P. Kao (Denver, Colorado).

The Heart Failure Congress 2013 is taking place during 25-28 May in Lisbon, Portugal. The Congress is the main annual meeting of the Heart Failure Association of the European Society of Cardiology (1).

Identifying peaks in admissions and mortality should assist targeted resource allocation at higher risk times. Seasonal, weekly and hourly variations have been observed in heart failure admissions but the reasons are unclear. Until now, the relationship of these variations with mortality and length of stay has not been investigated in a single study.

The current study (2) examined the impact of day, month and hour of admission on in-hospital mortality and length of stay in 949,907 hospitalisations for congestive heart failure. Data was analysed from all hospitals in the state of New York from 1994 to 2007. A greater number of factors were included in the analysis than ever before so that the researchers could confirm or refute previous theories on the reasons behind variations in heart failure morbidity and mortality (for example substance use).

The researchers found that daily heart failure admissions increased significantly over time (+1.1 admissions/day/year) while in-hospital mortality and length of stay decreased (-0.3%/year and -0.3 days/year, p END

First drug to improve heart failure mortality in over a decade

2013-05-25

Lisbon, 25 May 2013: Coenzyme Q10 decreases all cause mortality by half, according to the results of a multicentre randomised double blind trial presented today at Heart Failure 2013 congress. It is the first drug to improve heart failure mortality in over a decade and should be added to standard treatment, according to lead author Professor Svend Aage Mortensen (Copenhagen, Denmark). Heart Failure 2013 is being held from 25-28 May in Lisbon, Portugal. It is the main annual meeting of the Heart Failure Association of the European Society of Cardiology (1). Coenzyme ...

How do cold ions slide?

2013-05-25

Things not always run smoothly. It may happen, actually, that when an object slides on another, the advancement may occur through a 'stop and go' series in the characteristic manner which scientists call "stick-slip", a pervasive phenomenon at every scale, from earthquakes to daily-life objects, up to the "nano" dimension. Davide Mandelli, Andrea Vanossi and Erio Tosatti of the International School for Advanced Studies (SISSA) of Trieste have studied the conditions in which at the nanoscopic level the switch from smooth sliding to stick-slip regime occurs, simulating ...

Facial-recognition technology proves its mettle

2013-05-25

In a study that evaluated some of the latest in automatic facial recognition technology, researchers at Michigan State University were able to quickly identify one of the Boston Marathon bombing suspects from law enforcement video, an experiment that demonstrated the value of such technology. In the Pattern Recognition and Image Processing laboratory, Anil Jain, MSU Distinguished Professor of computer science and engineering, and Josh Klontz, a research scientist, tested three different facial-recognition systems. By using actual law-enforcement video from the bombing, ...

Researchers identify first drug targets in childhood genetic tumor disorder

2013-05-25

Two mutations central to the development of infantile myofibromatosis (IM)—a disorder characterized by multiple tumors involving the skin, bone, and soft tissue—may provide new therapeutic targets, according to researchers from the Icahn School of Medicine at Mount Sinai. The findings, published in the American Journal of Human Genetics, may lead to new treatment options for this debilitating disease, for which the only current treatment option is repeated surgical removal of the tumors. IM is an inheritied disorder that develops in infancy or even in utero and tumors ...

A new study, "Vegetable Cost Metrics Show That Potatoes and Beans Provide Most Nutrients Per Penny," published in the journal PLOS ONE, shows that potatoes are one of the best nutritional values in the produce aisle, providing one ...

Driving and hands-free talking lead to spike in errors: UAlberta study

2013-05-25

Talking on a hands-free device while behind the wheel can lead to a sharp increase in errors that could imperil other drivers on the road, according to new research from the University of Alberta. A pilot study by Yagesh Bhambhani, a professor in the Faculty of Rehabilitation Medicine, and his graduate student Mayank Rehani, showed that drivers who talk using a hands-free cellular device made significantly more driving errors—such as crossing the centre line, speeding and changing lanes without signalling—compared with just driving alone. The jump in errors also corresponded ...

Understanding the past and predicting the future by looking across space and time

2013-05-25

MADISON, Wis. – Studying complex systems like ecosystems can get messy, especially when trying to predict how they interact with other big unknowns like climate change. In a new paper published this week (May 20) in the Proceedings of the National Academy of Sciences, researchers from the University of Wisconsin–Madison and elsewhere validate a fundamental assumption at the very heart of a popular way to predict relationships between complex variables. To model how climate changes may impact biodiversity, researchers like Jessica Blois and John W. (Jack) Williams routinely ...

New analysis yields improvements in a classic 3-D imaging technique

2013-05-25

PERTH, AUSTRALIA — 9 May 2013 — Research conducted at Curtin University in Perth has enabled significant increases in image quality in a widely used 3D printing technique that is more than 100 years old. Anaglyph printing — think of the red-and-blue 3D glasses used to transform 2D images to 3D images in comics, magazines, books, and newspapers — came into being when the continuous-tone printed anaglyph was invented by French physicist Louis Ducos du Hauron in 1891. The technique works by combining the left and right images of a stereoscopic image pair into the red and ...
