Shingles vaccine may protect against dementia

Why are measles and other "eradicated" infectious diseases coming back?

Measles have made a comeback, with outbreaks in many states. The infection is extremely contagious and can be deadly. Most people getting measles were not vaccinated against it. Adults should get the vaccine if they were born after 1957 and didn't receive two doses. They should get a booster shot if they received the vaccine between 1963 and 1968, when the vaccine used was not as strong as the one that's been given since 1968.

Be alert to an increasingly common threat - tick-borne illnesses

Ticks are an increasingly common source of illness, especially in the summer months.

Stopping sepsis in its tracks

Sepsis causes or contributes to an estimated 20% of all deaths worldwide. The condition begins with an infection that spreads and over activates the immune system, which releases damaging inflammatory chemicals that lead to organ failure. Any infection can trigger sepsis, but those that begin in the lungs, urinary tract, gastrointestinal tract, or skin are more likely to do so. Older people are more susceptible to sepsis. The condition may be avoided by stopping bacterial or viral infections from occurring or worsening.

Decoding rheumatoid arthritis

Rheumatoid arthritis (RA) affects two to three times as many women as men. Scientists are uncovering RA's potential genetic and hormonal underpinnings, which point to potential reasons why women are more vulnerable. The newest treatments, called Janus kinase (JAK) inhibitors, resulted from research that has teased out delicate differences in immune system pathways. They block numerous proteins that ramp up inflammation fundamental to RA. The wide array of drug options now available for RA help doctors personalize therapies to each patient.
