It’s well known that preeclampsia, a condition characterized by a progressive rise in a pregnant woman’s blood pressure and appearance of protein in the urine, can have negative, even life-threatening impacts on the health of both mother and baby. Now, NIH-funded researchers have documented that preeclampsia is also taking a very high toll on our nation’s economic well-being. In fact, their calculations show that, in 2012 alone, preeclampsia-related care cost the U.S. health care system more than $2 billion.

These findings are especially noteworthy because preeclampsia rates in the United States have been steadily rising over the past 30 years, fueled in part by increases in average maternal age and weight. This highlights the urgent need for more research to develop new and more effective strategies to protect the health of all mothers and their babies.

Every year, hundreds of thousands of Americans acquire potentially life-threatening bacterial infections while in the hospital, nursing home, or other health-care settings [1]. Such infections can be caused by a variety of bacteria, which may respond quite differently to different antibiotics. To match a patient with the most appropriate antibiotic therapy, it’s crucial to determine as quickly as possible what type of bacteria is causing his or her infection. In an effort to improve that process, an NIH-funded team is working to develop a point-of-care system and smartphone app aimed at diagnosing bacterial infections in a faster, more cost-effective manner.

The portable new system, described recently in the journal Science Advances, uses a novel light-based method for detecting telltale genetic sequences from bacteria in bodily fluids, such as blood, urine, or drainage from a skin abscess. Testing takes place within small, optical cubes that, when placed on an electronic base station, deliver test results within a couple of hours via a simple readout sent directly to a smartphone [2]. When the system was tested on clinical samples from a small number of hospitalized patients, researchers found that not only did it diagnose bacterial infections about as accurately and more swiftly than current methods, but it was also cheaper. This new system can potentially also be used to test for the presence of antibiotic-resistant bacteria and contamination of medical devices.

Usually, I share cool science advances and major medical breakthroughs on this blog. But, today, I’d like to share something a little different, something of great importance for both your health and the advancement of biomedical research: new guidelines on how you can access your own health information.

The Health Insurance Portability and Accountability Act of 1996 (HIPAA) Privacy Rule has long supported the right of individuals to request and obtain copies of their medical records and other health information maintained by health-care professionals, medical facilities, and health insurance plans. However, due to the increasing use of online health-information technology and growing interest among Americans in being active participants in health-related decisions, the U.S. Department of Health and Human Services (HHS) recently issued much-anticipated guidance that serves to answer common questions and clarify key issues regarding access to health information under HIPAA. Think of it as a valuable personal roadmap for navigating a part of health care that is all-too-often confusing and frustrating!

Among the many reasons that people need easy, affordable access to their health records is to empower them to take more control over decisions regarding their health. Such information can help individuals improve their ability to monitor chronic conditions, stick with treatment plans, track progress in wellness programs, and identify and correct erroneous information. In addition, some people may want such access so they can directly contribute their health information to biomedical research projects. One such endeavor is the new, NIH-led Precision Medicine Initiative Cohort, in which 1 million or more volunteers will agree to share data, including information from their health records. Maintaining the security and privacy of individual information will be of paramount importance. In return, participants will have the highest levels of access to their study results, along with summarized results from across the cohort.

Transporting a patient in Nepal

A decade ago, as a medical student doing volunteer work at a hospital in India’s capital of New Delhi, Duncan Maru saw a young patient who changed the course of his career: a 12-year-old boy in a coma caused by advanced tuberculosis (TB). Although the child had been experiencing TB symptoms for four months, he was simply given routine antibiotics and didn’t receive the right drugs until his parents traveled hundreds of miles at considerable expense to bring him to a major hospital. After five weeks of intensive treatment, the boy regained consciousness and he was able to walk and talk again.

That’s quite an inspiring story. But it’s also a story that haunted Maru because he knew that if this boy had access to good primary care at the local level, his condition probably never would have become so critical. Determined to help other children and families in similar situations, Maru has gone on to dedicate himself to developing innovative ways of providing high-quality, low-cost health care in developing areas of the world. His “lab” for testing these efforts? The South Asian nation of Nepal—specifically, the poverty-stricken, rural district of Achham, which is located several hundred miles west of the national capital of Kathmandu.
