Salmonella-infected mice that were given antibiotics became superspreaders

Salmonella-infected mice that were given antibiotics became superspreaders

Salmonella-infected mice that were given antibiotics became sicker and began shedding far more bacteria in their feces than they had before. Some people infected with pathogens spread their germs to others while remaining symptom-free themselves. Now, investigators at the Stanford University School of Medicine believe they may know why Continue reading

Major breakthrough could help detoxify pollutants

Major breakthrough could help detoxify pollutants

Scientists at The University of Manchester hope a major breakthrough could lead to more effective methods for detoxifying dangerous pollutants like PCBs and dioxins. The result is a culmination of 15 years of research and has been published in Nature . It details how certain organisms manage to lower the toxicity of pollutants. Continue reading

Study questions 21-day quarantine period for Ebola

Study questions 21-day quarantine period for Ebola

As medical personnel and public health officials are responding to the first reported cases of Ebola Virus in the United States, many of the safety and treatment procedures for treating the virus and preventing its spread are being reexamined. One of the tenets for minimizing the risk of spreading the disease has been a 21-day quarantine period for individuals who might have been exposed to the virus. But a new study by Charles Haas, PhD, a professor in Drexel’s College of Engineering, suggests that 21 days might not be enough to completely prevent spread of the virus. Continue reading

Research findings could pave way for a fructose tolerance test

Research findings could pave way for a fructose tolerance test

Increased consumption of table sugar and high-fructose corn syrup has been linked to rising rates of obesity and type 2 diabetes in the United States and throughout the world. Both sweeteners are commonly found in processed foods and sugar-sweetened beverages, and both are made up of nearly equal amounts of two basic sugars, glucose and fructose. The effects of glucose ingestion in humans are well understood, in part, because they are easily assessed by performing a Glucose Tolerance Test, which measures serum glucose levels after glucose ingestion and has become the diagnostic cornerstone for modern diabetes care Continue reading

Pneumococcal vaccine reduces antibiotic-resistant infections in children by 62 percent

Pneumococcal vaccine reduces antibiotic-resistant infections in children by 62 percent

The pneumococcal vaccine recommended for young children not only prevents illness and death, but also has dramatically reduced severe antibiotic-resistant infections, suggests nationwide research being presented at IDWeek 2014™. Pneumococcal infection — which can cause everything from ear infections to pneumonia and meningitis — is the most common vaccine-preventable bacterial cause of death Continue reading

Tumor registry data find acadiana colon cancer rates among America’s highest

Tumor registry data find acadiana colon cancer rates among America’s highest

A special study using data from LSU Health New Orleans School of Public Health’s Louisiana Tumor Registry has found that colorectal cancer incidence rates in the Louisiana Acadian parishes are among the highest in the United States. This study appears to be the first to identify a high rate of cancer in a large, regional, US founder population, raising the possibility of a genetic predisposition. Continue reading

This study appears to be the first to identify a high rate of cancer in a large, regional, US founder population, raising the possibility of a genetic predisposition. Alternatively, an unidentified, robust environmental risk factor may be present. Continue reading

Mortality risk of overweight, obesity similar for blacks, whites

Mortality risk of overweight, obesity similar for blacks, whites

A study from American Cancer Society researchers finds the increased risk of premature death associated with a higher body mass index (BMI) is similar for African Americans and whites, in contrast to previous, smaller studies that indicated the association may be weaker for African Americans.

Potential link between breast cancer genes, salivary gland cancer

Potential link between breast cancer genes, salivary gland cancer

The risk of developing cancer in a salivary gland might be higher in people with mutations in either of two genes associated with breast and ovarian cancer, according to a new study by researchers at The Ohio State University Comprehensive Cancer Center — Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC — James) Continue reading
