Medical Monday: Breaking News from the World of Obstetrics and Gynecology

The World Health Organization will have convened on Friday to evaluate whether Zika is still to be classified as a “ public health emergency of international concern.” I am not sure of the criteria for such a classification, but it does not seem to me that we have yet seen most of the consequences of Zika in those yet to be born. Furthermore, it is not clear how Zika will fare though the turn of the seasons. 

The effects of Zika are generally serious to devastating. It is fascinating and confounding that these effects vary by geography. This means Zika has different effects depending on where the infection is contracted. The American Society for Tropical Medicine recently convened and examined this question which needs much more formal study. 

Women are more likely to get Zika from men than men are to get it from women. This is because the virus is now believed to suppress the vaginal immune response (Vaginal immune response ! Who knew ? ) and thus go undetected so it can establish infection in both mother and baby. 

Blood banks in affected states have been screening for Zika. Only 40 out of 800,000 positives have been found. This is not meant to represent an assessment of Zika prevalence in these states since the people who come to donate are screened and kept from donating if they have risk factors for the infection. 

In other news, there is another option for women with vaginal atrophy. Many older women and those who have had cancer have vaginal atrophy, which manifests as dry, thin, inelastic tissue. It also manifests as pain during intercourse. Fourteen percent of all women have low equal desire and sex related personal distress. Part of this in older women may related to vaginal atrophy. Unfortunately, this is not always addressed at the doctor’s office. Many such patients are not able or wiling to use vaginal estrogen. They may now use DHEA, dehydroepiandrosterone, an adrenal androgen, as a daily vaginal capsule, to help with this. The trade name will be Prasterone and it has recently been approved by the FDA ( Food and Drug Administration) for this use. 

The idea of using vaginal estrogen in breast cancer survivors has, until recently, not been considered due to concerns that the hormone enters the systemic circulation and might cause increased risk of recurrence. However a recent study published in JAMA Oncology has shown that estradiol secreting vaginal rings and intravaginal testosterone cream are both safe and effective therapies in those breast cancer patients who are receiving aromatase inhibitor (AI) therapy. 

In insurance news, President elect Trump has indicated that he favors preserving the prohibition against insurers denying coverage due to preexisting conditions. He also favors allowing parents to keep children on policies until the age of 26. An article in the Wall Street Journal recently opined that keeping these provisions without keeping the universal mandate (requirement for everyone to have insurance or be fined) and the funds it would bring in, would strain the coffers of health insurance companies bound to keep the first two provisions. 

At this point, hearsay reigns in matters of the new administration’s policies. Before the election, Republican politicians spoke of eliminating the individual mandate on health insurance. Now, there is talk of revamping it. Similarly, and more realistically, it is said that Medicaid under the new administration is more like to be altered than it is to be shrunk, as Republican candidates suggested. 

This column has covered the falling teen birth rate. Recent analysis of this data has shown that this is the case much more in urban compared to rural areas. Between 2007 and 2015, the teen birth rate fell 50% in cities, but only 37% in rural areas. Teen birth rates fell most among white and hispanic girls. 

In related news, a recent study in the American Journal of Public Health showed some interesting relationships between childbearing and longevity. Over 20,000 women were followed for over 16 years. Researchers discovered that a larger number of children is associated with less longevity in black women, but more longevity in white women. They also found that women who delay their first birth until at least 25 are more likely that their counterparts to live until age 90.

Medical Monday: Breaking News from the World of Obstetrics and Gynecology 

About 1.6 million pregnant women are at risk for Zika virus infection in South and Central  America. Now, health officials are concerned that local transmission of Zika virus has begun in southern Florida. This means the virus was acquired in Florida, instead of being acquired elsewhere while a person was traveling. This means that some of the mosquitos in Florida carry the virus.

In related news, the blood supply in South Florida is now considered to be potentially contaminated with Zika virus. The FDA ( Food and Drug Administration) has asked that all blood donations from South Florida halt until all donations can be screened for Zika virus.

In even more striking news, the CDC ( Centers for Disease Control)  is recommending that all pregnant women be screening for the Zika virus. 

As most of you know, Congress left for its seven week vacation without coming to an agreement on Zika funding. The President of the American College of Obstetricians and Gynecologists has written a strongly worded letter to Congress on this matter.

Proceedings from the National Academy of Sciences include research that indicates that women who enter menopause early age faster than other women. They were able to quantify this, saying that menopause speeds up cellular again about 6 %. They also indicated that poor sleep can trigger similar aging type changes. 

In related news, women who start menstruation late and who have menopause late compared to average are more likely to achieve 90 years of age. Information like this is useful in that it helps identify factors tied to longevity. 

Research from the Journal Circulation has indicate that only 2.5 hours of moderate exercise per week has measurable effects on heart disease risk in women. Let’s see, taking one day off per week leave six days for exercise. Divide that into 2.5 hours to get the time per day needed for exercise. Only 25 minutes per day needed to reduce cardiac risk !

Wellness Wednesday: Family and Social Support and Health

I have a pretty healthy family, and a pretty healthy group of friends. However, sometimes someone get sick or needs a surgery. I am always grateful and amazed at how people rally to help. At the same time, I think of my many patients who have to go it alone, even though they are not doing well. 

What is the relationship of social support to health ? It’s huge. I decided that if I write a blog post highlighting this interesting connection, that more people would connect with others in times of need. 

The most common form of social connection is marriage. Marriage is clearly associated with health. But there are some interesting particulars. Numerous studies over the last 150 years have noted this association. In more recent years, the association was questioned, on the hypothesis that perhaps healthier people marry. This turned out not to be true. In fact, unhealthier men were more likely to marry. 

If you parse the date further, the “ marriage effect “ is seen to be stronger as couples age. Moreover the effect is stronger for men than it is for women. Non married stable partners also have greater health than singles, however not as much as married people. There is not yet enough data to comment on whether same sex married couples share this health benefit of marriage. 

What are the particular mental and physical advantages associated with marriage and social support ? 

  • decreased depressive symptoms
  • better recovery from episodes of depression
  • lower heart rate and blood pressure 
  • lower serum cholesterol 
  • higher immune function 
  • reduced risk of Alzheimers 
  • better outcomes for hospitalized patients
  • decreased likelihood of chronic disease, disability, mental illness, and death

How do marriage and social support confer this improve effect on both mental and physical health ? There are several observations about those who are married, partnered or have good social support that seem likely to hold the answers : 

  • better social connectons
  • presence of companionship 
  • better emotional support 
  • better economic well being and more likely to be insured
  • more likely to keep medical appointments and get recommended screenings
  • more likely to take prescribed medications 
  • safer behaviors 
  • better nutrition 
  • more likely to get regular exercise

Dan Buettner in Blue Zones, identified social support as a principal correlate of extreme  longevity. He was focusing on groups of people around the world who lived healthy until past the age of 100. Regardless of place or culture, social support was key.

I think this is a powerful reminder for all of us to assess our our family and social connections. Are our relationships in good working order ? Those relationships may be more important than we realized.
