CID LISTED AMONG
“MOST INFLUENTIAL”

Clinical Infectious Diseases has been named as one of the "100 Most Influential Journals in Biology and Medicine" of the past 100 years by the Special Libraries Association. The list was compiled by the 680-plus members of SLA’s Biomedical and Life Sciences Division.

Trends in the Incidence of Methicillin‐Resistant Staphylococcus aureus Infection in Children’s Hospitals in the United States

Just this week, researchers reported that the incidence of MRSA infections among children admitted to pediatric hospitals in the United States more than tripled between 2002 and 2007. Researchers at the Children’s Hospital of Philadelphia and the University of Pennsylvania found cases of MRSA jumped from 6.7 per 1,000 admissions in 2002 to 21.1 cases per 1,000 admissions in 2007, according to a study released online Monday in the journal Clinical Infectious Diseases.

Another study, this one published in the U.S. journal Clinical Infectious Diseases in 2006, found that workers in meat-processing plants have a greater likelihood of being infected by some version of the H1N1 flu virus than the general population (the odds of pig farmers getting the disease are significantly greater again).

Every year, an estimated 915,000 people 65 and older get pneumonia, and 40 percent of them end up in hospitals, according to a 2004 paper in the journal Clinical Infectious Diseases. Pneumonia often kills older people, said Richard Stefanacci, a geriatrician at the University of the Sciences in Philadelphia.

Although it is a standard practice in high‐income countries, determination of the human immunodeficiency virus (HIV) load is not recommended in developing countries because of the costs and technical constraints. As more and more countries establish capacity to provide second‐line therapy, and as costs and technological constraints associated with viral load testing decrease, the question of whether determination of the viral load is necessary deserves attention. Viral load testing could increase in importance as a guide for clinical decisions on when to switch to second‐line treatment and on how to optimize the duration of the first‐line treatment regimen. In addition, the viral load is a particularly useful tool for monitoring adherence to treatment, performing sentinel surveillance, and diagnosing HIV infection in children aged <18 months. Rather than considering viral load data to be an unaffordable luxury, efforts should be made to ensure that viral load testing becomes affordable, simple, and easy to use in resource‐limited settings.
