UC Santa Barbara Might Use Unapproved Vaccine to Combat Meningitis Outbreak
Health officials confirmed late last week that they are considering administering the unapproved vaccine Bexsero to halt the spread of a bacterial meningitis outbreak that has sickened four students at UC Santa Barbara. Three of the students have recovered fully, with the fourth requiring the amputation of both feet. The U.S. Centers for Disease Control and Prevention (CDC) is working with the California state and Santa Barbara County departments of public health to determine whether the vaccine would be effective against the strain; Bexsero, which is not yet approved for use in the United States, is for type B meningococcal disease. The U.S. Food and Drug Administration recently granted Princeton University permission to use the vaccine, after eight students became sick from a similar strain of what has struck UC Santa Barbara.

AAP Calls for Ban on U.S. Sale of Raw or Unpasteurized Milk
The risk of infection has led the American Academy of Pediatrics (AAP) Committee on Infectious Diseases and Committee on Nutrition to not only recommend against the consumption of raw or unpasteurized milk by pregnant women, babies and kids, but to call for the complete ban of its sale in the United States. Pasteurization kills bacteria by heating the milk to a minimum of 161 degrees Fahrenheit for at least 15 seconds before cooling it quickly; at least 97 percent of U.S. dairy products are pasteurized. From 1998 through 2011 there were 148 disease outbreaks related to raw milk or raw milk products, leading to 284 hospitalizations and two deaths. "It's kind of like riding in a car with seatbelts," said Kathryn Boor, dean of Cornell University’s school’s Agriculture and Life Sciences, who was not involved in the study. "If you've got the opportunity for a safety barrier, which would be pasteurization, why wouldn't you use it?" Read more on food safety.
Study: Lack of Sleep in Kids Increases Blood Pressure
Lack of adequate sleep can lead to higher blood pressure even in children who are a healthy weight, according to a new study in the journal Pediatrics. Monitoring 143 Chinese youth in a sleep lab, the researchers determined that one fewer hour of sleep per night increased systolic blood pressure by 2 millimeters of mercury (mm/Hg) and diastolic blood pressure by 1 mm/Hg. All of the participants, ages 10-18, were normal weight and did not have sleep apnea. "Pediatricians must screen for diabetes, and [high blood pressure] in teenagers with sleep loss besides screening for snoring and sleep apnea in obese teenagers," said Sanjeev Kothare, MD, a pediatric sleep expert at NYU Langone Medical Center, who was not involved in the study. The National Sleep Foundation recommends 10-11 hours of sleep per night for children ages 5-12, and at least 8.5 hours per night for teenagers. Read more on pediatrics.
