A recent study published in the American Journal of Emergency Medicine found that sex-differences exist in emergency room evaluation and treatment times for patients presenting with a heart attack [1]. The retrospective study conducted at the University of Pennsylvania analyzed treatment times for over 250 patients with confirmed heart attacks. The study authors found that women, on average, wait 3 minutes longer to receive an initial EKG than men. Additionally, women wait 7 minutes longer than men for a heart attack treatment protocol to be activated, with the total average time being 25.5 minutes for women and 18.5 minutes for men. Current recommendations suggest that anyone presenting with a suspected heart attack should be evaluated and a treatment protocol initiated in less than 20 minutes [2]. Thus, women may be subject to additional heart damage as time passes without intervention.

According to the American Heart Association, women may experience a wide variety of symptoms during a heart attack which can include:

  • Chest pain
  • Shortness of breath
  • Sweating
  • Pain in the arms, jaw, back or stomach
  • Nausea or vomiting

 However, the most common symptom is chest pain or discomfort which is experienced by both men and women. It may be possible that sex-based bias exists in the initial diagnosis of heart attacks as evidence by this research. Additional studies which explore sex-differences within evaluation, diagnosis, and treatment of heart attacks and other cardiovascular disease may promote enhanced survival for both men and women.

This year, the Summer Olympics are scheduled to be held in Rio De Janeiro, Brazil, throughout the month of August. However, several athletes, coaches, staff, and journalists have decided to stay home this year, citing concerns for Zika virus infection. Brazil is currently experiencing a Zika virus outbreak with over 148,00 suspected cases of Zika virus disease as of May 2016 [1]. According to the Centers for Disease Control (CDC), the Zika virus disease is spread through the bite of an infected mosquito and can cause symptoms such as fever, rash, and joint pain. While in a healthy individual, Zika virus disease may only cause a mild illness, less is known about its effects in the elderly, immunocompromised, and those with underlying health problems. Perhaps most concerning is the risk of associated birth defects, such as microcephaly, which can occur if a pregnant woman is infected with Zika virus. Furthermore, it has recently been shown that Zika virus can be transmitted through sexual contact. This has left many individuals scheduled to travel to Brazil concerned for the health of themselves and their families.

Savannah Guthrie, a TV journalist who is currently pregnant, has reported that she will not be attending the Olympics due to concerns for the Zika virus [3]. Additionally, professional golfer Rory McIlroy has stated the same [4]. Those who do plan on traveling to the Olympic games, such as U.S. men’s volleyball coach John Speraw, are taking numerous precautions to avoid Zika virus. Speraw plans wearing long sleeves, staying indoors, and as an extra measure of precaution, he will freeze his sperm prior to the Olympics in the event that he contracts the virus while in Brazil [5].

The CDC recommends that all individuals traveling to Brazil practice enhanced precautions which include:

  • Covering all exposed skin with long sleeved shirts and pants
  • Applying insect repellent containing DEET
  • Pre-treating clothes with the repellant permethrin
  • Staying indoors in air-conditioning

To date, no mosquito-borne transmission of Zika virus has been reported in the United States. However, as of June 22nd, there are 820 confirmed cases of individuals living in the U.S. who have contracted the virus while travelling abroad. If you plan on travelling abroad or to other U.S. territories this summer, check with the CDC for travel health notices and updates for local precautions.

For some women, the onset of menopause can be fraught with unpleasant symptoms such as hot flashes, night sweats and vaginal dryness. If a woman wishes to avoid or is not a candidate for hormone replacement therapy, lifestyle and dietary modifications may provide some relief. Last week, an article published in the Journal of the American Medical Association analyzed the results of over 62 studies which examined the use and effectiveness of plant-based therapies on menopausal symptom relief [1]. The authors found that use of phytoestrogen-containing foods and dietary supplements may reduce hot flashes and vaginal dryness but not night sweats.

Phytoestrogens are naturally-occurring compounds found in plants which have a similar chemical structure to the hormone estrogen. When ingested, phytoestrogens can mimic, albeit to a lesser extent, the actions of estrogen since they “look alike” to our bodies. Phytoestrogens can be found in various fruits, vegetables, and even wine. Soybeans, in particular, have a high phytoestrogen content. For some individuals, there is increasing evidence that consuming soy-based products may provide relief from menopausal symptoms [1,2].

 Because phytoestrogens have estrogen-like properties, it was thought that consuming food which contained high amounts of phytoestrogens, such as soy, could increase your risk for breast cancer. However, there is no concrete evidence which suggests that this is true. So if you are looking for a natural approach to curb your menopause symptoms, increasing phytoestrogen-rich foods in your diet may be a safe and healthy alternative.

Recently, the use of talcum powder has become a controversial issue as growing evidence suggests that its use may be related to an increased risk of ovarian cancer. Talcum powder, also known as talc, is a mineral composed of the elements magnesium, silicon, and oxygen. As a common household product, talcum powder can be used as an antiperspirant or in the application of cosmetics. Because of its ability to absorb moisture it may be applied to sensitive areas of the body, such as the genitals, to prevent chaffing.

A new study published in the journal Epidemiology, analyzed the use of talcum powder in over 4,000 women with and without ovarian cancer. The authors found that use of talcum powder in the genital region may increase a woman’s risk for ovarian cancer by 33%, especially in instances where the powder was used daily.

More research is necessary to determine how talcum powder causes cancer. In the meantime, the American Cancer Society suggests that it may be prudent to avoid or limit use of products containing talc, if you are concerned about developing ovarian cancer.  

Although the overall lifetime risk of developing ovarian cancer is low, it is one of the most deadly gynecological cancers. Therefore it is important to recognize some of the major signs and symptoms of ovarian cancer for early detection and diagnosis.

Signs and Symptoms

  • Lower abdominal pain or pressure
  • Weight gain or weight loss
  • Abnormal periods
  • Gas, nausea, or vomiting
  • Trouble eating or feeling “full” after eating

While these symptoms may be associated with other benign conditions, it is always important to discuss any questions or concerns you may have with your doctor.
