Romanian health authorities on Friday, Nov. 30, 2018, temporarily closed the maternity hospital in the capital after over a dozen babies born there recently were diagnosed with a […]Continue Reading ...
A new study by the University of Birmingham has found that seven in every eight children who have their tonsils removed are unlikely to benefit from the operation. Researchers analysed the electronic medical records of over 1.6 million children from more than 700 UK general practices dating between 2005 and 2016. They found that out […]Continue Reading ...
A team of scientists in Australia warned in September of the spread of a bacteria, staphylococcus epidermidis, immune to all known drugs Drug-resistant bacteria killed more than 33,000 people in the European Union in 2015, according to new research published this week warning that superbugs were “threatening modern healthcare.” In a study published in the […]Continue Reading ...
Electron microscopy of influenza virus. Credit: CDC A large international team of researchers has developed a four-in-one antibody approach to fighting influenza infections. In their paper published in the journal Science, the group describes the development of the antibody and how well it worked in test mice. Despite a lot of research by scientists over […]Continue Reading ...
Hepatitis B and hepatitis C are viral infections, which are mostly transmitted by blood. Often unnoticed, they can become chronic, causing irreversible damage to the liver. There is a discussion whether regular screening of the general population or of particular risk groups could contain these diseases, for example by early detection and treatment or by […]Continue Reading ...
Credit: CC0 Public Domain Dear Mayo Clinic: I have had hyperthyroidism for just over one year, and medication does not seem to keep it in check. I do not want to have my thyroid removed. But I’m nervous about radioactive iodine treatment, which is what was recommended. Is it safe? What are the risks? A: […]Continue Reading ...
Dengue and Zika are transmitted by the same mosquito species and their distribution now overlaps in many tropical regions of the world. Credit: Jenna Hambrick, La Jolla Institute for Immunology To say that the immune system is complex is an understatement: an immune response protective in one context can turn deadly over time, as evidenced […]Continue Reading ...
In dromedary camels, MERS infection only leads to harmless cold symptoms. In humans they can lead to a serious illness. Credit: Katiekk, Shutterstock What causes only a harmless cold in camels can be fatal for humans: an infection with the MERS virus. Since its discovery in 2012, the virus was detected in approximately 2,000 patients […]Continue Reading ...
A normal mouse lung (left) and one with abnormal activation of hedgehog. Credit: Tien Peng Valerie Chang kept waking up breathless in the middle of the night. As a regular swimmer and non-smoker, she figured it was a fluke, a remnant of her childhood asthma, perhaps. But after a lung test, doctors told her that she […]Continue Reading ...
Most nosebleeds aren’t serious and will stop on their own or by following self-care steps. SEEK EMERGENCY MEDICAL CARE IF NOSEBLEEDS: – Follow an injury, such as a car accident—Involve a greater than expected amount of blood—Interfere with breathing—Last longer than 30 minutes even with compression—Occur in children younger than age 2—Don’t drive yourself to […]Continue Reading ...
Before patients receive intravenous (IV) antimicrobial infusion therapy outside of the hospital—whether at home, a doctor’s office or a skilled nursing facility—an infectious diseases (ID) specialist should review the order to ensure the most appropriate treatment, suggest updated guidelines released by the Infectious Diseases Society of America (IDSA). Once they begin receiving outpatient parenteral antimicrobial […]Continue Reading ...
Fig. 1: The mechanism by which group A Streptococcus (GAS) evades the immune system. The immune receptor Mincle recognizes MGDG, an immunoactivating lipid present on GAS, and then activates the immune system to eliminate the invading pathogen. However, DGDG, an antagonistic lipid present on GAS, inhibits Mincle activity, thereby evading the host immune system. Credit: […]Continue Reading ...
