Mayo Clinic finds steroids may shorten hospital stay for pneumonia patients

2013-02-28
(Press-News.org) ROCHESTER, Minn. — Patients with pneumonia may spend fewer days in the hospital if they are given steroids along with antibiotics and supportive care. That's the finding of a Mayo Clinic analysis of eight randomized-controlled clinical trials involving more than 1,100 patients. The results appear in the March issue of the Journal of Hospital Medicine.

"Given that the average hospital stay for community-acquired pneumonia can range from nine to 23 days, the prospect of speeding recovery, even by a day or two, is helpful," says co-author M. Rizwan Sohail, M.D., a Mayo infectious disease specialist.

Pneumonia is a major health risk, especially in the elderly, the very young and those with chronic lung diseases. Five percent to 15 percent of pneumonia patients die from it, depending on its severity and the treatment administered, recent studies report.

Mayo researchers reviewed eight clinical trials conducted from 2000 to 2011. Most of the research studied patients between 60 and 80. While steroid use didn't prevent deaths, for those who survived the pneumonia, it reduced their hospital stays an average of 1.21 days.

The researchers say that while the findings are significant, the data were not strong enough for them to recommend routine use of steroids for pneumonia patients; more study is needed. They add that continuing any steroids patients may already be taking is reasonable.

The study was led by Majid Shafiq, M.D., a former Mayo Clinic researcher currently at Johns Hopkins University.

A similar, but unrelated study by A.R. Khan, M.D., involving researchers at Mayo Clinic and other institutions, found that use of certain lipid-lowering medicines, commonly referred to as statins, may have a role in reducing the risk of developing community-acquired pneumonia and associated mortality. That study, published last month in PLOS ONE, reviewed 18 clinical trials. The evidence was considered less reliable due to design issues, bias and other factors in the original studies.

Vaccination remains the most powerful tool in infection prevention, researchers say. The Centers for Disease Control and Prevention recommends that all adults 65 or older should receive the pneumonia vaccine and that anyone 19 or older with risk factors such as immune deficiency or chronic lung disease also should get it. ### About Mayo Clinic Mayo Clinic is a nonprofit worldwide leader in medical care, research and education for people from all walks of life.

'Crazy-busy' Canadians under pressure on the job

2013-02-28
Having more control in the workplace can have negative consequences for individuals but it depends on the form of job control, according to new research out of the University of Toronto. Sociologist Scott Schieman measured a range of work conditions using data from a national survey of 6,004 Canadian workers. To measure levels of job pressure, he asked study participants questions such as: "How often do you feel overwhelmed by how much you had to do at work?" "How often do you have to work on too many tasks at the same time?" and "How often do the demands of your job ...

Discoveries suggest icy cosmic start for amino acids and DNA ingredients

2013-02-28
Using new technology at the telescope and in laboratories, researchers have discovered an important pair of prebiotic molecules in interstellar space. The discoveries indicate that some basic chemicals that are key steps on the way to life may have formed on dusty ice grains floating between the stars. The scientists used the National Science Foundation's Green Bank Telescope (GBT) in West Virginia to study a giant cloud of gas some 25,000 light-years from Earth, near the center of our Milky Way Galaxy. The chemicals they found in that cloud include a molecule thought ...

Mutation altering stability of surface molecule in acid enables H5N1 infection of mammals

2013-02-28
A single mutation in the H5N1 avian influenza virus that affects the pH at which the hemagglutinin surface protein is activated simultaneously reduces its capacity to infect ducks and enhances its capacity to grow in mice according to research published ahead of print today in the Journal of Virology. "Knowing the factors and markers that govern the efficient growth of a virus in one host species, tissue, or cell culture versus another is of fundamental importance in viral infectious disease," says Charles J. Russell of St. Jude Children's Research Hospital, Memphis, ...

Trackable drug-filled nanoparticles -- a potential weapon against cancer

2013-02-28
Tiny particles filled with a drug could be a new tool for treating cancer in the future. A new study published by Swedish scientists in Particle & Particle Systems Characterization shows how such nanoparticles can be combined to secure the effective delivery of cancer drugs to tumour cells – and how they can be given properties to make them visible in MR scanners and thus rendered trackable. The team, which consisted of scientists from Karolinska Institutet (KI) and the Royal Institute of Technology (KTH) in Stockholm, and from Chalmers University of Technology in Gothenburg, ...

Study finds diabetes does not increase risk of total knee surgical complications

2013-02-28
PASADENA, Calif., Feb. 27, 2013 – Patients with diabetes who undergo total knee replacement surgery do not have increased risk of surgical complications compared to those patients without diabetes, according to a Kaiser Permanente study published today in The Journal of Bone and Joint Surgery. Researchers studied the electronic health records of more than 40,000 patients who had a first-time knee replacement from January 1, 2001 through December 31, 2009. Of the patients studied, 12.5 percent had controlled diabetes, 6.2 percent had uncontrolled diabetes and 81.3 percent ...

About 15 percent of patients with Wolfram syndrome do not meet current diagnostic criteria

2013-02-28
Researchers at IDIBELL and CIBERER Virginia Nunes and Miguel López de Heredia have collected data from 400 patients with Wolfram syndrome published worldwide in the last fifteen years to better understand the natural history of disease. The findings lead them to propose a revision of the diagnostic criteria of the disease because 15% of paediatric patients escape from diagnosis. The results of this review have been published this week in the online edition of the journal Genetics in Medicine to coincide with the World Day of rare diseases, on February 28th. These rare ...

Wars on editing Wikipedia articles, uncovered

2013-02-28
CSIC researcher Maxi San Miguel, director of the Institute for Cross-Disciplinary Physics and Complex Systems (IFISC), a joint research Institute of CSIC and the University of the Balearic Islands, explains: "We say there is a conflict when there is an unusual high number of editing and corrections in articles related to some topic or personage on which there are very divergent or polarised opinions. Our model identifies the different types of behaviours according to two main parameters: the reposition rate of editors as time goes by; and the level of tolerance, that is, ...
