Nausea And Speeding Heart Can Be Signs Of Flu In Pregnant Women

Nausea in pregnant women tends to fade after the first three months, but during the second and third trimesters it can be a sign of flu, researchers at UT Southwestern Medical Center have found in a study of expectant women who sought medical care.

“People don’t necessarily think of influenza when you include the symptoms of nausea or vomiting, but our study showed that they are common with influenza in pregnancy,” said Dr. Vanessa Rogers, assistant professor of obstetrics and gynecology and lead author of the study, which appears in the May edition of Obstetrics and Gynecology.

“Both physicians and patients should be aware of these findings so treatment is not delayed,” she said. “I think our findings should encourage people to be vigilant and to take symptoms seriously.”

Adults with flu tend not to have nausea or vomiting, according to the Centers for Disease Control and Prevention. These symptoms are more typical in children.

The researchers studied the cases of pregnant women during the 2003-2004 flu season, when the most common strain of influenza caused more severe symptoms than usual. There also were more cases of flu than expected, because the vaccine given that year didn’t match the strain that was predominant. Read more

Over Consumption Of Selenium Can Increase Cholesterol

A new study from the University of Warwick has discovered taking too much of the essential mineral selenium in your diet can increase your cholesterol by almost 10%.

Selenium is a trace essential mineral with anti-oxidant properties. The body naturally absorbs selenium from foods such as vegetables, meat and seafood. However, when the balance is altered and the body absorbs too much selenium, such as through taking selenium supplements, it can have adverse affects.

A team led by Dr Saverio Stranges at the University’s Warwick Medical School has found high levels of selenium are associated with increased cholesterol, which can cause heart disease.

In a paper recently published in the Journal of Nutrition, the research team examined the association of plasma selenium concentrations (levels of selenium in the blood) with blood lipids (fats in the blood).

The researchers found in those participants with higher plasma selenium (more than 1.20 µmol/L) there was an average total cholesterol level increase of 8% (0.39 mmol/L (i.e. 15.1 mg/dL). Researchers also noted a 10% increase in non-HDL cholesterol levels (lipoproteins within your total cholesterol that can help predict the risk of someone suffering a heart attack or chest pain). Also, of the participants with the highest selenium levels, 48.2% admitted they regularly took dietary supplements. Read more
