Main Points:

  • Many U.S. women don’t know most of the warning signs of a stroke.
  • Hispanic women were less likely than others to know the warning signs of a stroke.
  • Nearly all women knew that they should immediately call 9-1-1 if they suspected that they were having a stroke.

SAN FRANCISCO — Many U.S. women don’t know most of the warning signs of a stroke, according to research presented at the American Heart Association’s Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2014 Scientific Sessions.

The study is also published in the American Heart Association journal, Stroke.

In a phone survey of 1,205 U.S. women:

  • More than half (51 percent) of the women identified sudden weakness or numbness on one side of the face, arms or legs as a warning sign of a stroke.
  • Less than half (44 percent) identified difficulty speaking or garbled speech as a warning sign.

Less than a fourth identified other signs of a stroke, including:

  • sudden severe headache (23 percent);
  • unexplained dizziness (20 percent); and
  • sudden vision loss (18 percent).

U.S. survey reveals 2.7 million living with chronic Hep C virus

Main Points:

A survey of U.S. households conducted between 2003 and 2010 revealed that approximately 2.7 million US residents are infected with chronic hepatitis C virus (HCV). This figure marks a decrease by about 500,000 cases identified by a similar analysis conducted between 1999 and 2000.

Published in:

Annals of Internal Medicine

Study Further:

Chronic HCV infection is an important public health issue because those who are infected are at high risk for liver disease and other chronic illnesses. Treatment can cure the disease and decrease risk for death, yet many persons infected with HCV do not know they have it. Currently, more people in the U.S. die from HCV than from HIV infection. Knowledge of the number of persons with HCV infection is critical for public health and policy planning.

Investigators conducted a nationally representative household survey to estimate the prevalence of HCV and to identify risk factors for infection. They found that the estimated prevalence of chronic HCV infection in the U.S. is about 2.7 million, a decrease of about 500,000 cases since the previous survey. This decrease could be attributed from deaths due to the disease.

Preterm Infants More Likely to Have Elevated Insulin Levels in Early Childhood

Main Points:

Chicago – Researchers have found that preterm infants are more likely to have elevated insulin levels at birth and in early childhood compared to full-term infants, findings that provide additional evidence that preterm birth may be a risk factor for type 2 diabetes, according to a study in the February 12 issue of JAMA.

Published in:

JAMA

Study Further:

In the United States, 1 in 9 live births are preterm, and l in 5 live births among African Americans are preterm. “There is growing evidence that fetal and early life events may result in permanent metabolic alterations, such as type 2 diabetes and metabolic syndrome [a combination of risk factors that increase the risk for heart disease, diabetes, and stroke]. Although available studies in children and adults support the hypothesis that preterm birth may result in adverse metabolic alterations, it is unclear whether the observed association between preterm birth, later insulin resistance, and type 2 diabetes stems from alterations in insulin metabolism during the in utero [in the uterus] period or in early childhood,” according to background information in the article.

Study Finds Small Increased Risk of Kidney Disease Following Kidney Donation

Main Points:

Chicago – An analysis of nearly 100,000 kidney donors finds that there is a small increased lifetime risk of developing end-stage renal disease following donation compared with healthy nondonors, although the risk is still much lower than that in the general population, according to a study in the February 12 issue of JAMA.

Published in:

JAMA

Study Further:

Every year in the United States, approximately 6,000 healthy adults accept the risks of kidney donation to help family members, friends, or even strangers. “It is imperative that the transplant community, in due diligence to donors, understands the risk of donation to the fullest extent possible and communicates known risks to those considering donation,” according to background information in the article.

Study Examines Legislative Challenges to School Immunization Mandates

Main Points:

Chicago – From 2009-2012, 36 bills introduced in 18 states sought to modify school immunization mandates, with the majority seeking to expand exemptions although none of the bills passed, according to a study in the February 12 issue of JAMA.

Published in:

JAMA

Study Further:

“School immunization mandates, implemented through state-level legislation, have played an important role in maintaining high immunization coverage in the United States,” according to background information in the article. Immunization mandates permit exemptions that vary from state to state in terms of type of exemption (e.g., religious, personal belief, medical). Certain types of exemptions (especially personal belief exemptions) and the ease of obtaining them can help predict the increased disease risk among exemptors themselves and in the communities in which they reside
