Dr. Doussou Touré arrives for work at Coléah Medical Centre in Guinea. She washes her hands from a bucket set up in front of the building, proceeds to a screening area where her temperature is checked and recorded and only then enters the bustling facility that she supervises.
Occupational exposure to blood and body fluids (BBF) is a serious – even deadly -- hazard faced daily by many healthcare personnel. Percutaneous injuries from sharps, a well-known vehicle of bloodborne disease, contribute heavily to this important public health issue. In fact, an estimated 35 million workers worldwide are at risk of exposure to pathogens from sharps injuries sustained in a variety of healthcare settings and scenarios. Such exposures, although preventable, are often regarded as “just part of the job.”
The development of antiretroviral therapy, a combination of drugs that slows the replication of HIV in the body, has transformed the treatment of this infection. What was once a certain death sentence is now a chronic condition that people can live with for decades. But this therapy has drawbacks. There are side effects, including kidney problems, decreased bone density, and gastrointestinal problems. And if a person discontinues his or her treatment, even missing a few doses, the level of the virus in the body is able to rebound quickly.
In Uganda, taking a bath before surgery, closing the door to the operating theater and ensuring surgeons clean their hands properly can be the difference between life and death. A study involving more than 650 surgical patients, showed the rate of infections halved after new measures were introduced. As a result, patients are spending less time in hospital, resulting in cost-savings for both the patient and the hospital.
Aedes mosquitoes carrying the bacterium Wolbachia--found inside the cells of 60 percent of all insect species--are drastically less able to transmit Zika virus, say researchers at Brazil's Oswaldo Cruz Foundation (FIOCRUZ) in a study published May 4 in Cell Host & Microbe.
In a study prompted in part by suggestions from people with mental illness, Johns Hopkins researchers found that a history of Candida yeast infections was more common in a group of men with schizophrenia or bipolar disorder than in those without these disorders, and that women with schizophrenia or bipolar disorder who tested positive for Candida performed worse on a standard memory test than women with schizophrenia or bipolar disorder who had no evidence of past infection.
