Women who experience vaginal bleeding for more than one day during the first trimester of pregnancy may be more likely to have a smaller baby, compared to women who do not experience bleeding in the first trimester, suggest researchers at the National Institutes of Health. On average, full-term babies born to women with more than one day of bleeding in the first trimester were about 3 ounces lighter than those born to women with no bleeding during this time. Additionally, infants born to women with more than a day of first trimester bleeding were roughly twice as likely to be small for gestational age, a category that includes infants who are healthy but small, as well as those whose growth has been restricted because of insufficient nutrition or oxygen or other causes.

In 1948, more than 5,000 people in the little town of Framingham, Mass., volunteered for a study to find answers about the mysterious, growing epidemic of heart disease. Every two years for decades, they had a physical exam, gave blood and urine samples and answered questions about their health. Their children and grandchildren joined too. Because of them, we now know the big risk factors for cardiovascular disease and have saved millions of lives through new prevention strategies, drugs, procedures and education.

Mayo Clinic researchers are studying the clinic’s opioid prescribing practices after surgery, discovering areas for improvement based on that evidence, and applying it to optimize care for individual patients. The result in the Mayo Clinic Department of Orthopedic Surgery is a 48 percent reduction in the amount of opioids prescribed for hip and knee replacement surgery. The team also noted that the prescription refill rate remained the same. The research was published recently in Clinical Orthopaedics and Related Research.
