In an effort to one day eliminate the need for an annual flu shot, a group of researchers from the National Institutes of Health (NIH) and Icahn School of Medicine at Mount Sinai are exploring the surface of influenza viruses, which are covered by a protein called “hemagglutinin” (HA). This particular protein is used like a key by viruses to open cells and infect them, making it an ideal target for efforts to help the body's immune system fight off a wide range of influenza strains.

One of the most promising new approaches to slowing the spread of HIV is pre-exposure prophylaxis (PrEP), a once-a-day medication that people who don't have HIV can take to prevent becoming infected. But that strategy only works if people at risk for contracting HIV become and remain fully engaged in preventive care and actually take the pills. In the real world of clinical practice, that has often proved tricky.

Women have claimed for years that their bodies react differently whether they're pregnant with a male or female baby. Some studies suggest that a baby's sex could play a role in why some women report differences with morning sickness, cravings and other symptoms based on the sex of their baby. Now, evidence published in the February issue of the journal Brain, Behavior and Immunity, shows the sex of a baby is associated with pregnant women's immune responses.

The non-profit research and development organization Drugs for Neglected Diseases initiative (DNDi) has released results of a study in South Africa that will make it easier for healthcare workers to treat children living with HIV who are co-infected with tuberculosis (TB). The study, presented as a late-breaker this week at the Conference on Retroviruses and Opportunistic Infections (CROI) in Seattle, provides essential evidence and data to counter the negative interactions between two critical HIV and TB treatments.

Sepsis is a major public health problem and the focus of national quality measures and performance improvement initiatives. Understanding what is happening with sepsis rates and outcomes is thus an area of great importance. However, tracking sepsis rates and outcomes is challenging because it is a heterogeneous syndrome without a definitive "gold standard" test. In the February issue of CHEST, investigators compared the effectiveness of claims-based surveillance using ICD-9 codes with clinical-based data and specific diagnostic parameters. Their findings suggest that surveillance based on clinical criteria is a more reliable way to track cases of septic shock.

More than 1 million healthcare associated infections (HAIs) occur within the U.S. healthcare system every year. According to a study per-formed by the Centers for Disease Control and Prevention (CDC), approximately 1 of every 25 hospitalized patients in the U.S. develop an HAI, meaning that nearly 650,000 patients contract one of these infections annually. These infections can lead to serious illness and result in the loss of thousands of lives each year. In addition they impose a tremendous financial burden, estimated to be more than a billion dollars annually in the U.S.

Malaria mosquitoes prefer to feed -- and feed more -- on blood from people infected with malaria. Researchers from Stockholm University, the Swedish University of Agricultural Sciences and KTH Royal Institute of Technology have discovered why. The findings can lead to new ways to fight malaria without using poisonous chemicals. The results will be published in the next issue of the journal Science.

Viral and human genetics together account for about one third of the differences in disease progression rates seen among people infected with the human immunodeficiency virus (HIV), according to new research published in PLOS Computational Biology. The findings suggest that patient genetics influences disease progression by triggering mutations in the HIV viral genome.
