Iron-deficiency anemia linked to memory deficits in children
Medscape Medical News
Iron-deficiency anemia (IDA) is linked to memory deficits in children, according to the results of a study reported online in Pediatrics. "IDA in infancy is associated with cognitive deficits, which may persist later in life," write R. Colin Carter, MD, from Children's Hospital Boston and Harvard Medical School in Boston, Massachusetts, and colleagues. "Socioemotional deficits are also consistently observed in infants with IDA, but it is not known whether these deficits affect cognitive function." The goal of the study was to determine effects of IDA on specific functions involved in infant cognition, as well as the effect of socioemotional deficits related to IDA in modulating these effects.More

Gene variants associated with susceptibility to postsurgical chronic pain
Medscape Medical News
A new study has found associations between variants of the gene CACNG2 and patients' experiences of chronic pain after breast cancer surgery. The gene was previously known to encode stargazin, a protein involved in alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA)-type glutamate receptors, and a possible subunit of calcium channels implicated in epilepsy. The present findings contribute information about the physiology of neuropathic pain and its potential treatment.More

Spread of whooping cough raises concern
HealthDay News via Bloomberg Businessweek
Amidst the largest outbreak of whooping cough in decades, public health officials in California are urging residents, particularly pregnant women and those who come into contact with infants, to make sure they're immunized for the highly contagious disease. With the incidence of whooping cough also higher than last year in Michigan, South Carolina, Ohio and upstate New York, there's growing concern whooping cough will continue to spread, said Jennifer Liang, an epidemiologist with the U.S. Centers for Disease Control and Prevention.More

Report: Fido's food could be making kids sick
The Associated Press via Google News
Fido's food may be making kids sick, a government report warns, detailing the first known salmonella outbreak in humans, mostly young children, linked to pet food. The outbreak sickened 79 people in 21 mostly eastern states, between 2006 and 2008. Almost half of the victims were children aged 2 and younger. Dry pet foods are an under-recognized source of salmonella infections in humans, and it's likely other illnesses since then were unknowingly caused by tainted pet food, said Casey Barton Behravesh, the report's lead author and a researcher at the federal Centers for Disease Control and Prevention.More

How viruses jump from hosts: Secrets of rabies transmission in bats discovered
Science Daily
HIV-AIDS. SARS. Ebola. Bird Flu. Swine Flu. Rabies. These are emerging infectious diseases where the viruses have jumped from one animal species into another and now infect humans. This is a phenomenon known as cross-species transmission (CST) and scientists are working to determine what drives it.More

Pneumococcal bacteria trigger increase in hemolytic uremic syndrome
Infection Control Today
Introduction of the PCV-7 vaccine to prevent invasive pneumococcal disease (IPD) has led to a shift in the types of bacteria causing hemolytic uremic syndrome (HUS) — an important cause of acute kidney failure in children, reports a study in the August issue of the Pediatric Infectious Disease Journal. Very rare a decade ago, HUS related to Streptococcus pneumonia bacteria (SP-HUS) now occurs in more than 5 percent of children with IPD. When SP-HUS does develop, it is generally caused by bacterial strains not covered by the PCV-7 vaccine, according to the new study.More
