Urinary tract infections (UTIs) are common, and widespread antibiotic resistance has led to urgent calls for new ways to combat them. Researchers at University of California, San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences report that an experimental drug that stabilizes a protein called HIF-1alpha protects human bladder cells and mice against a major UTI pathogen. The drug might eventually provide a therapeutic alternative or complement to standard antibiotic treatment.
According to the Centers for Disease Control and Prevention, vaccines have saved more the 732,000 lives in the past two decades and studies have repeatedly shown that they are the best way to protect our communities from some of the deadliest illnesses. Still, there is a lot of confusing information about the safety and effectiveness of vaccines and it can be difficult to discern fact from fiction.
A new study led by the University of Iowa shows swine farmers are six times more likely to be carriers of staph bacteria, including the MRSA strain, than others. Results appear online in the journal Clinical Infectious Diseases.
Young HIV positive women are more likely to practice safer sex if they have an equitable perception of gender roles, according to new research involving the University of Southampton.

Scientists report that a new study of HIV-infected men in Uganda has identified a temporary, but potentially troublesome unintended consequence of the procedure: a possible increased risk of infecting female sexual partners while circumcision wounds heal.
Current public health guidelines recommend that only gay men and people with HIV should be routinely screened for extragenital gonorrhea and chlamydia, given the high burden of these sexually transmitted infections (STIs) in this at-risk population.
As a fast-moving virus forces U.S. poultry producers to kill millions of chickens and turkeys, Dr. Richard French of Becker College explains why this strain of avian influenza is different from others—and says food producers should brace for an even greater impact and loss.
A new microneedle patch being developed by the Georgia Institute of Technology and the Centers for Disease Control and Prevention (CDC) could make it easier to vaccinate people against measles and other vaccine-preventable diseases.

Tick-borne diseases are a major public health problem around the world. Now, just in time for spring and the explosion of ticks in forests, lawns and trails, a new study by researchers from China and the University of Maryland School of Medicine has uncovered a never-before-seen illness transmitted by ticks. It’s possible that the disease could be a “substantial health threat” to humans and animals in areas where the carrier tick is common, the authors say.
Discussing your sexual history with a doctor, or anyone for that matter, can be an uncomfortable experience. But for many transgender people, the conversation never takes place because they aren’t seeking health care.
