Mothers over 40 more at risk of preterm birth

Maternal age over 40 is associated with an increased risk of preterm birth Mothers aged 30-34 years old may have the lowest risk of preterm birth
Pregnant mothers aged 40 and over may have an increased risk for preterm birth, regardless of confounding factors, according to a new study.
Pregnant mothers aged 40 and over may have an increased risk for preterm birth, regardless of confounding factors, according to a study published January 31, 2018 in the open-access journal PLOS ONE by Florent Fuchs from CHU Sainte Justine, Canada and colleagues.

Maternal age at pregnancy has been increasing worldwide and so has the risk for preterm birth. However, the association between maternal age and preterm birth remains a topic of ongoing research.

Fuchs and colleagues sought to investigate the impact of maternal age on preterm birth in a large cohort. The researchers analyzed the previously-collected data from the QUARISMA randomized controlled trial, which had taken place in 32 hospitals in Quebec, Canada, from 2008 to 2011.

The researchers identified five different age groups among the 165,282 pregnancies included in the study, and compared them based on maternal characteristics, gestational and obstetric complications, and risk factors for prematurity. Some of the known risk factors identified more commonly in older mothers (40 and over) included placental praevia, gestational diabetes, medical history, use of assisted reproduction technologies and occurrence of an invasive procedure. On the other hand, nulliparity, past drug use and smoking were more prevalent in younger mothers (30 and under).

Even after adjusting for confounding factors, the researchers found that advanced maternal age (40 or over) was associated with preterm birth. Meanwhile, a maternal age of 30-34 years was associated with the lowest risk of prematurity.

Recent study reveals reproductive risk factors of heart disease and stroke for women

Dr. Lela Emad of the Women’s OB/GYN Medical Group talks about a new study while emphasizing that healthcare providers need to be vigilant about screening women for cardiovascular disease.

Dr. Lela Emad of the Women’s OB/GYN Medical Group talks about a new study while emphasizing that healthcare providers need to be vigilant about screening women for cardiovascular disease.

Research containing new data on risk factors for heart attack and stroke comes from a very large study of more than half a million men and women of up to the age of 69 who were recruited between 2006 and 2010. Ultimately the health of 267,440 women and 215,088 men was tracked over the course of the study, or until participants had their first heart attack or stroke, whichever came first. None of the participants had cardiovascular disease when they entered the study. From this, more than 9,000 cases of cardiovascular disease were recorded, a third of which were in women.

Highlights of the study found higher risk factors for women who experienced:

  • periods starting before age 12 (10% increased risk)
  • early menopause (33% increased risk of cardiovascular disease, 42% of stroke)
  • pregnancy complications (up to 44% higher risk depending on factor)
  • Hysterectomy (12% cardiovascular disease, heart disease 20%)

This study was large, and the researchers determined a range of potentially influential factors (see full results here).

“This study is particularly important for healthcare providers,” explains Dr. Lela Emad of the Women’s OB/GYN Medical Group of Santa Rosa. “Routine screening for cardiovascular issues is something we do for our patients and something we might be able to target better now, given this new information. This is something every healthcare provider needs to be aware of.”

Heart Disease: a serious health factor for women

The American Heart Association says cardiovascular diseases and stroke cause one out of three deaths in women every year, killing approximately one woman every 80 seconds. An estimated 44 million women in the U.S. are affected by cardiovascular diseases. A whopping ninety percent of women have one or more risk factors for heart disease or stroke and fewer women survive heart attacks then do men.

More than 5 million people in the United States suffer from heart failure, less than 50 percent of those with heart failure live a full five years following diagnosis. The deadly duo of heart disease and stroke are among the most prevalent and costly health complications today. Heart disease or stroke wreak havoc on people’s lives measured in increased medical bills, lost wages and decreased quality of living.

  • 5 million heart attacks and strokes occur every year in the United States
  • 800,000 deaths occur from heart disease each year, a total of 1 in every 3 deaths – about the same number as die from cancer, respiratory disease and accidents – combined
  • 150,000 of deaths from heart disease occur in people under age 65
  • $320 billion in health care costs and lost productivity were attributed to heart disease and stroke in 2011

The top five ways to manage heart disease include; controlling high blood pressure (with the help of a healthcare provider), a daily routine of physical activity (at least 20 minutes per day), eat whole foods (avoid processed alternatives), avoid excess salt and quit smoking.

“Fitness is a factor for women of all ages, and even more significant for those who have known risk factors for heart disease and stroke,” says Dr. Emad.  “Lifestyle changes such as exercising, dieting, quitting smoking and cutting back on caffeine are all examples of the most effective ways to maintain a healthy heart.”

Can working nights increase a woman’s cancer risk?

Among female nurses alone, those who worked the night shift had an increased risk of breast (58 percent), gastrointestinal (35 percent), and lung cancer (28 percent) compared with those that did not work night shifts. Of all the occupations analyzed, nurses had the highest risk of developing breast cancer if they worked the night shift.

Researchers performed a meta-analysis using data from 61 articles comprising 114,628 cancer cases and 3,909,152 participants from North America, Europe, Australia, and Asia. The articles consisted of 26 cohort studies, 24 case-control studies, and 11 nested case-control studies. These studies were analyzed for an association between long-term night shift work and risk of 11 types of cancer. A further analysis was conducted, which looked specifically at long-term night shift work and risk of six types of cancer among female nurses.

Overall, long-term night shift work among women increased the risk of cancer by 19 percent. When analyzing specific cancers, the researchers found that this population had an increased risk of skin (41 percent), breast (32 percent), and gastrointestinal cancer (18 percent) compared with women who did not perform long-term night shift work. After stratifying the participants by location, researcher Xuelei Ma found that an increased risk of breast cancer was only found among female night shift workers in North America and Europe.

“We were surprised to see the association between night shift work and breast cancer risk only among women in North America and Europe,” said Ma. “It is possible that women in these locations have higher sex hormone levels, which have been positively associated with hormone-related cancers such as breast cancer.”

Among female nurses alone, those who worked the night shift had an increased risk of breast (58 percent), gastrointestinal (35 percent), and lung cancer (28 percent) compared with those that did not work night shifts. Of all the occupations analyzed, nurses had the highest risk of developing breast cancer if they worked the night shift.

“Nurses that worked the night shift were of a medical background and may have been more likely to undergo screening examinations,” noted Ma. “Another possible explanation for the increased cancer risk in this population may relate to the job requirements of night shift nursing, such as more intensive shifts.”

The researchers also performed a dose-response meta-analysis among breast cancer studies that involved three or more levels of exposure. They found that the risk of breast cancer increased by 3.3 percent for every five years of night shift work.

“By systematically integrating a multitude of previous data, we found that night shift work was positively associated with several common cancers in women,” said Ma. “The results of this research suggest the need for health protection programs for long-term female night shift workers.

“Our study indicates that night shift work serves as a risk factor for common cancers in women,” said Ma. “These results might help establish and implement effective measures to protect female night shifters. Long-term night shift workers should have regular physical examinations and cancer screenings.

“Given the expanding prevalence of shift work worldwide and the heavy public burden of cancers, we initiated this study to draw public attention to this issue so that more large cohort studies will be conducted to confirm these associations,” he added.

A limitation of this work is a lack of consistency between studies regarding the definition of “long-term” night shift work, with definitions including “working during the night” and “working at least three nights per month.” Additional limitations include significant between-study heterogeneity and publication bias.

New study reveals: Women Really are Better Survivors

Women survive crises better than men Newborn girls are hardier than newborn boys during famines, epidemics
Women today tend to live longer than men almost everywhere worldwide — in some countries by more than a decade. Now, three centuries of historical records show that women don’t just outlive men in normal times: They’re also more likely to survive even in the worst of circumstances, such as famines and epidemics.
Women today tend to live longer than men almost everywhere worldwide — in some countries by more than a decade.

Now, three centuries of historical records show that women don’t just outlive men in normal times: They’re more likely to survive even in the worst of circumstances, such as famines and epidemics, researchers report.

Most of the life expectancy gender gap was due to a female survival advantage in infancy rather than adulthood, the researchers found. In times of adversity, newborn girls are more likely to survive.

The fact that women have an edge in infancy, when behavioral differences between the sexes are minimal, supports the idea that explanation is at least partly biological, the researchers say.

Led by Virginia Zarulli, an assistant professor at the University of Southern Denmark, and James Vaupel, a research professor at Duke University, the team analyzed mortality data going back roughly 250 years for people whose lives were cut short by famine, disease or other misfortunes.

The data spanned seven populations in which the life expectancy for one or both sexes was a dismal 20 years or less. Among them were working and former slaves in Trinidad and the United States in the early 1800s, famine victims in Sweden, Ireland and the Ukraine in the 18th, 19th and 20th centuries, and Icelanders affected by the 1846 and 1882 measles epidemics.

In Liberia, for example, freed American slaves who relocated to the West African country in the 1800s experienced the highest mortality rates ever recorded. More than 40 percent died during their first year, presumably wiped out by tropical diseases they had little resistance to. Babies born during that time rarely made it past their second birthday.

Another group of people living in Ireland in the 1840s famously starved when a potato blight caused widespread crop failure. Life expectancy plummeted by more than 15 years.

Overall the researchers discovered that, even when mortality was very high for both sexes, women still lived longer than men by six months to almost four years on average.

Girls born during the famine that struck Ukraine in 1933, for example, lived to 10.85, and boys to 7.3 — a 50 percent difference.

When the researchers broke the results down by age group, they found that most of the female survival advantage comes from differences in infant mortality. Newborn girls are hardier than newborn boys.

The results suggest that the life expectancy gender gap can’t be fully explained by behavioral and social differences between the sexes, such as risk-taking or violence.

Instead, the female advantage in times of crisis may be largely due to biological factors such as genetics or hormones. Estrogens, for example, have been shown to enhance the body’s immune defenses against infectious disease.

“Our results add another piece to the puzzle of gender differences in survival,” the researchers said.

The findings were published Jan. 8, 2018, in the early online edition of Proceedings of the National Academy of Sciences.

Researchers use MRI for the first time ever in effort to decode early labor

Scientists are using the latest imaging techniques usually used to map the brain to try and understand why some pregnant women miscarry or go into early labor.
Scientists are using the latest imaging techniques usually used to map the brain to try and understand why some pregnant women miscarry or go into early labor.

They have developed 3D images of the cervix, the load bearing organ which lies at the base of the womb and stops a developing baby from descending into the birth canal before the due date.

Around a quarter of miscarriages during the fourth to sixth month of pregnancy (mid-trimester) occur because of weaknesses in the cervix.

The researchers at the University of Leeds hope by developing a detailed image of its structure, they can develop ways of monitoring women for signs of potential problems before they become pregnant.

Mr Nigel Simpson, Associate Professor in Obstetrics and Gynaecology, said: “Ultrasound monitoring is used to identify women at risk — where their cervix is unable to support the pregnancy. But little is known about why that problem develops.

“This research is attempting to answer that question.”

MRI techniques were used to create 3D images of the cervix. This is the first time extremely high resolution imaging has been used to understand the detailed micro-structure of this organ.

The research is published in the international obstetrics and gynaecology journal, BJOG.

James Nott, from the Faculty of Medicine and Health and lead author, said: “A lot of our understanding of the biology of the cervix is rooted in research carried out 50 years ago.

“By applying the imaging techniques that have been used on the brain, we can get a much clearer understanding of the tissue architecture that gives the cervix its unique biomechanical properties.”

The images reveal a fibrous structure running along the upper part of the cervix. The fibres are much more pronounced near to where it joins the womb. The fibres are made of collagen and smooth muscle and form a ring around the upper aspect of the cervical canal.

During pregnancy, these fibres provide a strong supporting barrier — keeping the fetus and amniotic sac in place and preventing micro-organisms from entering the uterus.

The images reveal that these support tissues are less prominent further down the cervix as it joins the birth canal.

During labour, the body releases chemicals which result in the cervix opening and allowing the baby to enter the birth canal.

But there are medical conditions where earlier in the pregnancy, the cervix fails to support the baby, leading to a miscarriage or premature birth.

Mr Simpson said: “This study’s findings have encouraged us to explore new imaging techniques to check the integrity of these fibres before or during pregnancy in order to identify at-risk mums, intervene earlier, and so prevent late pregnancy loss and pre-term birth.”

The study was funded by Cerebra, the charity for children with brain conditions.

The scientists used diffusion tensor MRI, which is a technology that can remotely sense different types of tissue based on their water content.

Start the New Year Right: Quit the nicotine habit using the latest research model for success

In addition to lowering the effects of nicotine withdrawal, exercise is by far the best thing women can do to improve health.The Women’s OB/GYN Medical Group shares insight into how women who have a nicotine habit can take advantage of the latest research trends for quitting that might just guarantee success; starting an exercise routine.

Smoking is a bad habit for anyone and for women it poses very specific problems, particularly for pregnant women and women who are considering pregnancy. “Now is the perfect time for women of all ages to make a commitment to stop smoking,” says Dr. Lela Emad Obstetrician & Gynecologist. “In light of the latest research, we’re asking all of our patients who smoke or use nicotine products, to make the commitment to change this one lifestyle habit, and start the New Year on a better track toward health.”

The Study 

Experts at St George’s University of London set out to understand the underlying mechanism that seems to be exercise’s way of supporting the body against nicotine dependence and withdrawal. The study revealed that even moderate exercise noticeably reduces the severity of nicotine withdrawal symptoms. The findings help to validate the protective effect of exercise during smoking cessation; against the development of physical dependence, which may help smokers in giving up the habit by reducing the severity of withdrawal symptoms.

The Impact of Smoking

According to the Center of Disease Control and Prevention cigarette smoking remains the leading cause of preventable death and disability in the United States, despite a significant decline in the number of people who smoke. More than 16 million Americans have at least one disease caused by smoking.

“If exercise works to decrease the symptoms associated with nicotine withdrawal, then taking up an exercise routine and quitting the habit go hand in hand,” Dr. Emad says. “Statistics show that only 30 percent of women quit smoking when they find out they are pregnant, if we could make a dent in that number, it will have a positive impact on the well-being of both mothers and their children.”

Cigarette smoking alone kills more than 480,000 Americans each year. It causes direct damage to the body, which can lead to long-term health problems. We’ve all heard that smoking causes cancer, lung and heart disease, and stroke, but smoking also causes specific problems for women’s health including:

  • Decreased bone density
  • Rheumatoid arthritis
  • Cataracts
  • Gum disease
  • Ulcers
  • Depression
  • Menstrual problems
  • Low birth-weight
  • Pre-term delivery

In addition to lowering the effects of nicotine withdrawal, exercise is by far the best thing women can do to improve health. Exercise has been found to increase a person’s overall energy level and it releases endorphins—which in turn increases a person’s happiness quotient. Ongoing research suggests that as little as 2.5 hours weekly (about 20 minutes a day) of moderate aerobic exercise such as walking provides all the major health benefits a body needs to stay healthy.

“What a great resolution for women of all ages to make for this New Year; stop smoking, start exercising,” Dr. Emad said.

Discontinuance of Hormone Therapy May Be Hazardous to the Heart

A new study demonstrates that the risk of cardiac and stroke death actually increases in the first year after discontinuation of HT.
Hormone therapy (HT) continues to be a hotly debated topic. The benefits of estrogen to the heart, however, appear to be universally accepted. A new study demonstrates that the risk of cardiac and stroke death actually increases in the first year after discontinuation of HT. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).

Since publication of the Women’s Health Initiative (WHI) clinical trial data, there has been significant disagreement over the various risks and benefits of HT. What remains relatively unchallenged is the fact that estrogen has rapid beneficial vascular effects and that shorter periods between the onset of menopause and the initiation of HT provide greater protection against cardiovascular disease. This beneficial relationship between HT and protection against heart disease has led to the speculation that withdrawal from HT could result in clinically significant changes in arterial function. Although previous studies have shown that termination of estradiol-based HT led to significant increases in the risk of cardiac and stroke deaths, particularly during the first year, these results were questioned because women with documented heart problems had not been excluded from the study.

This study, however, involving more than 400,000 Finnish women excluded women with prior cardiac or stroke events. The results of the study, published in the article “Increased cardiac and stroke death risk in the first year after discontinuation of postmenopausal hormone therapy,” showed that discontinuation of HT was associated with an increased risk of cardiac and stroke death during the first posttreatment year, especially in women who discontinued HT aged younger than 60 years. This increased risk was not observed in women aged 60 years or older at the time of discontinuation.

“Since the initial Women’s Health Initiative reports, studies have shown that hormone therapy has many benefits and is safer than originally thought. This is especially true for symptomatic menopausal women younger than age 60 and within 10 years of menopause, as these women had fewer heart events and less risk of mortality,” says Dr. JoAnn Pinkerton, NAMS executive director. “This new study suggests that younger women may have a higher risk of heart disease and stroke during the first year of discontinuation. Thus, women and their healthcare providers need to consider the benefits and risks of starting and stopping hormone therapy before making any decisions.”

Fewer Cesarean Deliveries Associated with Midwife-Attended Hospital Births

Women who gave birth at hospitals with a larger percentage of midwife-attended births were less likely to have two specific medical interventions, cesarean delivery and episiotomy, a new, hospital-level analysis. These findings raise the possibility that greater access to midwifery care, which is low in the United States, might enhance perinatal care and lower costs for low-risk women.

In a new, hospital-level analysis by health policy researcher Laura Attanasio at the University of Massachusetts Amherst and Katy Kozhimannnil at the University of Minnesota School of Public Health, they report that women who gave birth at hospitals that had a larger percentage of midwife-attended births were less likely to have two specific medical interventions, cesarean delivery and episiotomy.

Attanasio, an assistant professor of health policy and management at UMass Amherst’s School of Public Health and Health Sciences, explains that a growing body of research at the individual level has shown that compared to women cared for by physicians, women considered at low-risk for complications in childbirth who receive care from midwives have good outcomes that include lower use of interventions such as cesarean delivery.

The researchers analyzed hospital-level data reported in New York State over one year. Details appear in the current Journal of Midwifery & Women’s Health. Their study analyzes the experiences of individual women; an accompanying policy brief looks at hospital rates of medical interventions at the time of childbirth.

The authors say their findings raise the possibility that greater access to midwifery care, which is low in the United States, might enhance perinatal care and lower costs for low-risk women. In 2014, the year of the study, Attanasio and Kozhimannil point out that midwives attended just 9 percent of U.S. births, compared to more than 66 percent in other western countries such as Australia, France and the U.K.

They add, “More midwife-attended births may be correlated with fewer obstetric procedures, which could lower costs without lowering the quality of care. This raises the possibility of improving value in maternity care through greater access to midwifery care for childbearing women in the United States.”

The researchers used the Healthcare Cost and Utilization Project State Inpatient Database data for New York and New York State Department of Health data on the percentage of midwife-attended births at hospitals in the state in 2014 to estimate the association between the hospital-level percentage of midwife-attended births and four outcomes among low-risk women: induced labor, cesarean delivery, episiotomy and severe obstetric morbidity — that is, unintended outcomes of labor or delivery that have significant negative effects on the mother’s health.

Of the 126 hospitals included, the researchers say, about 25 percent of the hospitals had no midwives present. About 50 percent had some midwives present, but they attended less than 15 percent of births, while at 7 percent of the hospitals, midwives attended over 40 percent of births. They controlled for such variables as mother’s age, insurance type, and diagnosis of diabetes and hypertension.

Key findings were:

  • Women who gave birth at hospitals with more midwife-attended births had lower odds of delivering by cesarean and lower odds of episiotomy.
  • Hospital-level percentage of midwife-attended births was not associated with changes in labor induction or severe obstetric morbidity.

Attanasio says, “This study is contributing to a body of research which shows that good outcomes for women at low risk in childbirth go hand-in-hand with lower use of medical procedures. And, there is increasing attention now to overuse of cesarean and other procedures that are not resulting in better outcomes for mom and baby.”

Kozhimannil adds that the findings imply that a greater midwifery presence may have important clinical benefits. “From a policy perspective, this study should encourage legislators and regulators to consider efforts to safely expand access to midwifery care for low-risk pregnancies,” she notes.

Several states are considering expanding midwives’ scope of practice as New York State did in 2010 for certified nurse midwives, Attanasio says. “I hope that this work contributes to the evidence related to promoting the quality and value in maternity care that midwives can bring. A number of studies have shown that expanding their scope of practice and giving midwives more autonomy can increase women’s access to midwifery care.”

Pesticide residue on produce may affect fertility


Eating more fruits and vegetables with high-pesticide residue was associated with a lower probability of pregnancy and live birth following infertility treatment for women using assisted reproductive technologies, report researchers.
The JAMA Network Journals reports that eating more fruits and vegetables with high-pesticide residue was associated with a lower probability of pregnancy and live birth following infertility treatment for women using assisted reproductive technologies, report researchers.
Is preconception intake of fruits and vegetables with pesticide residues associated with outcomes of assisted reproductive technologies?

Animal studies suggest ingestion of pesticide mixtures in early pregnancy may be associated with decreased live-born offspring leading to concerns that levels of pesticide residues permitted in food by the U.S. Environmental Protection Agency may still be too high for pregnant women and infants.

325 women who completed a diet questionnaire and subsequently underwent cycles of assisted reproductive technologies as part of the Environment and Reproductive Health (EARTH) study at a fertility center at a teaching hospital in Boston between 2007 and 2016 by Jorge E. Chavarro, M.D., Sc.D., of the Harvard T. H. Chan School of Public Health, Boston, and colleagues.

Researchers categorized fruits and vegetables as having high or low pesticide residues using a method based on surveillance data from the U.S. Department of Agriculture. They counted the number of confirmed pregnancies and live births per cycle of fertility treatment.

This is an observational study. In observational studies, researchers observe exposures and outcomes for patients as they occur naturally in clinical care or real life. Because researchers are not intervening for purposes of the study they cannot control natural differences that could explain study findings so they cannot prove a cause-and-effect relationship.

Results of the study indicate that eating more high-pesticide residue fruits and vegetables (for example, strawberries and raw spinach) was associated with a lower probability of pregnancy and live birth following infertility treatment. Eating more low-pesticide residue fruits and vegetables was not associated with worse pregnancy and live birth outcomes.

Limitations of the study include that the study estimated exposure to pesticides based on women’s self-reported intake combined with pesticide residue surveillance data rather than through direct measurement. The study also cannot link specific pesticides to adverse effects.

“In conclusion, intake of high-residue FVs [fruits and vegetables] was associated with lower probabilities of clinical pregnancy and live birth among women undergoing infertility treatment. Our findings are consistent with animal studies showing that low-dose pesticide ingestion may exert an adverse impact on sustaining pregnancy. Because, to our knowledge, this is the first report of this relationship to humans, confirmation of these findings is warranted.”
