Study: Global Child TB Rates 25 Percent Higher than Previously Realized
The true number of children who develop tuberculosis (TB) each year in the 22 countries with the worst TB rates is nearly 25 percent higher than the World Health Organization (WHO) estimated as recently as 2012, according to a new study in The Lancet Global Health. Researchers used mathematical modeling to determine that approximately 650,000 children in these countries develop TB each year; the WHO estimate was 530,000. The study also determined that approximately 15 million children are exposed to TB every year and 53 million are living with latent TB infections which can become infectious active TB. While the findings are troubling, they also indicate promising ways to reduce the risk. "Our findings highlight an enormous opportunity for preventive antibiotic treatment among the 15 million children younger than 15 years of age who are living in the same household as an adult with infectious TB,” said lead author Peter Dodd, MD, from the University of Sheffield in the United Kingdom, in a release. "Wider use of isoniazid therapy for these children as a preventative measure would probably substantially reduce the numbers of children who go on to develop the disease." Read more on global health.
Severe Obesity Can Cut a Person’s Lifespan by Nearly 14 Years
Severe obesity can take nearly 14 years off a person’s life, according to a new study in the journal PLOS Medicine. Using data from 20 previous studies, researchers determined that severe obesity—defined as a body mass index (BMI) greater than 40—can cut lives short by anywhere from 6.5 to 13.7 years, due to increased risk of health problems such as heart disease, cancer and diabetes. "We found that the death rates in severely obese adults were about 2.5 times higher than in adults in the normal weight range," said lead investigator Cari Kitahara, a research fellow at the U.S. National Cancer Institute, according to HealthDay. Approximately 6 percent of U.S. adults are severely obese; severe obesity accounts for approximately 509 deaths per 100,000 men annually and 382 deaths per 100,000 women annually.

HHS: $100M for 150 New Community Health Centers
The U.S. Department of Health and Human Services (HHS) has announced approximately $100 million in available funds for communities to expand access to affordable, high-quality primary care through an estimated 150 new community health centers in 2015. Currently there are approximately 1,300 health centers with more than 9,200 service sites providing care to more than 21 million people in the United States and its territories. The centers, made possible under the Affordable Care Act (ACA), have also helped approximately 4.7 million people enroll for ACA coverage. Read more on community health.
