MedicalResearch.com Interview with: Dr Jiabi Qin, MD, PhD Xiangya School of Public Health Central South University Changsha, China  MedicalResearch.com: What is the background for this study? Response: Congenital heart defects (CHDs), defined as a gross structural abnormality of the heart or intrathoracic great vessels occurring in embryonic period and affected nearly 1% of lives births, is the most common of all congenital defects and remains a major cause of mortality and morbidity in fancy and childhood. With a worldwide prevalence of CHDs now estimated to be 1.35 million newborns with CHDs every year, the number of CHDs is steadily increasing, representing a major global health burden. The association between maternal alcohol exposure and the risk of congenital heart defects (CHDs) has been explored, but little is known about the association between paternal alcohol exposure and the risk of CHDs. Furthermore, subsequent studies regarding the association between alcohol exposure and the risk of congenital heart defects have not yield consistent results. Therefore, given the inconsistency of existing literatures and insufficient evidence of primary studies, further an update meta-analysis based on the new and previously is evidently required. Especially, to our knowledge, any meta-analysis between paternal alcohol exposure and the risk of CHDs have not been conducted.

Response: Asymptomatic bacteriuria, or ASB, is when someone has bacteria in their urine but does not have any signs or symptoms of a urinary tract infection. For pregnant people, this can be a major health concern resulting in severe, even life-threatening, infections that can lead to serious harms for both the mother and the baby. The Task Force’s primary finding in updating its recommendation on this topic was that screening for ASB continues to be beneficial in preventing complications and preserving the health of mothers and their babies during pregnancy.

What are the main findings? Response: Alcohol, tobacco, and cannabis are the most commonly used substances during pregnancy. High alcohol consumption has been linked with preterm birth, and tobacco and/or cannabis use is associated with low birth weight. Much of what we know about predictors of drug use during pregnancy comes from the United States and Australia, with limited studies in Canada. The objective of our study was therefore to assess the relative effects of socioeconomic, demographic, and mental health risk factors associated with drug use during pregnancy. Our retrospective cohort study consisted of 25,734 pregnant women from Southwestern Ontario. We found that maternal depression was the top risk factor associated with all three substances. Compared to women who were not depressed during their pregnancy, women who were depressed were 2.2 times more likely to use alcohol (95% CI: 1.6, 2.9), 1.7 times more likely to smoke tobacco (95% CI: 1.5, 2.0), and 2.6 times more likely to use cannabis (95% CI: 2.0, 3.4).

MedicalResearch.com Interview with: [caption id="attachment_50581" align="alignleft" width="86"]Maria S. Altieri, MD, MS Invasive surgery fellow Washington University, St. Louis, MO Dr. Altieri[/caption] Maria S. Altieri, MD, MS Invasive Surgery Stony Brook, NY MedicalResearch.com: What is the background for this study? What are the main findings? Response: For majority of residents, training years coincide with prime child bearing years.  Historically, surgical residency has not been conducive for having children, as it is one of the most demanding experiences, requiring long hours, high stress levels, and the acquisition of clinical and technical skills over a short period of time. However, with recent trends towards a more favorable work-life balance and the 80-hour work week, more male and female residents are having children or considering having children during training.  Thus, the topic of parental leave during residency is becoming more fundamental.  However, there is little research on the attitudes of residents towards their pregnant peers and parental leave. We wanted to examine the perceptions of surgical trainees towards parental leave and pregnancy during residency.  Through understanding the perceptions of current residents, obstacles could be identified which could lead to potential changes in policies that could help to normalize parenthood and parental leave during surgical training.

What are the main findings? Response: A growing body of evidence suggests that the circumstances surrounding the 2016 presidential election may have had a uniquely negative impact on the health of U.S. Latino population. Few studies, however, have evaluated the population health implications of the election for Latina mothers and their children. We used national data and methods that control for temporal patterning to test the hypothesis that preterm birth rose above otherwise expected levels among Latina women in the U.S. following the election of Donald Trump. We find that the number of preterm births among Latina women increased above expected levels following the election. Specifically, we find 3.5 percent more preterm births among Latinas than projected for nine months following election.

What are the main findings? Response: For women with lupus, pregnancy has long been considered high-risk and associated with both medical and obstetric complications. In the 1960s and 1970s, pregnancy was thought to be contraindicated in lupus patients. Beginning in the 1980s, and especially in the 1990s, many studies identified specific risk factors for pregnancy complications and proposed best-practice management guidelines. We wished to see whether these advances improved pregnancy outcomes for lupus patients. Our study showed a decline in maternal mortality and other outcomes in lupus patients. The improvement in pregnancy outcomes was observed more so in lupus patients than those without lupus.

Nuss, Ph.D. Assistant Professor Louisiana State University Health Sciences Center School of Public Health New Orleans, LA  MedicalResearch.com: What is the background for this study? Response: Childhood obesity rates in the U.S. have been increasing within the past 30 years. We can point to things like sedentary lifestyle, energy-dense, nutrient-poor foods and savvy marketing techniques of large food corporations that target kids and their parents to buy food items that aren’t healthy. That said, we do know that women who have an unhealthy weight status (as measured by BMI ≥ 25) tend to have offspring that eventually attain an unhealthy weight status themselves. Aside from environmental factors, could this be due to maternal programming or perhaps something in the breastmilk? Or both? We saw some interesting research that showed breastfed infants/toddlers born to asthmatic moms were more likely to develop asthma. Furthermore, this association became stronger the longer the infants/toddlers were breastfed. The conclusion here is that it must be something in the breastmilk. We knew that asthma and obesity are both inflammatory in nature and that there are specific pro- and anti-inflammatory and obesogenic bioactive compounds in human breastmilk. Some have been studied before but there were no studies at the time that tied all of the pieces together. If we could target specific compounds in the milk that were associated with unhealthy growth patterns in infants then we could perhaps be more specific in how we fight this problem.

MedicalResearch.com Interview with: Ashraf Habib, MDChief of the Division of Women’s Anesthesia and Professor of AnesthesiologyDuke University Ashraf Habib, MD Chief of the Division of Women’s Anesthesia Professor of Anesthesiology Duke University  MedicalResearch.com: What is the background for this study? What are the main findings? Response: This was a multicenter study conducted in 13 clinical sites in the United States enrolling patients undergoing elective Cesarean-section and receiving spinal anesthesia. 186 patients were enrolled and randomized to receive EXPAREL, a long-acting, non-opioid option to manage postsurgical pain, administered via transversus abdominis plane (TAP) field block, mixed with plain bupivacaine or TAP block with plain bupivacaine alone. A TAP block numbs the nerves that supply the abdominal wall. We presented the data at the 51st Annual Meeting of the Society of Obstetric Anesthesia and Perinatology (SOAP) in Phoenix, AZ. We aimed to collect clinical evidence that a multimodal postsurgical pain regimen using a TAP block with EXPAREL (bupivacaine liposome injectable suspension) together with regularly scheduled acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs) could reduce opioid consumption more so than a standard multimodal pain control approach that combines TAP block with standard bupivacaine, regularly scheduled acetaminophen, and NSAIDs.

MedicalResearch.com Interview with: Dr-Romy GaillardRomy Gaillard MD PhD LifeCycle Project-Maternal Obesity and Childhood Outcomes Study Group Erasmus MC MedicalResearch.com: What is the background for this study?   Response: Obesity among women of reproductive age is a major problem for society. Scientists have long known that maternal weight before and during pregnancy are associated with pregnancy outcomes. Gestational weight gain is necessary to ensure healthy development of the fetus, but too much weight gain is associated with a higher risk of pregnancy complications. The magnitude of the associations of maternal weight before and during pregnancy with the risks of pregnancy complications, as well as the optimal amount of weight that especially obese women should gain during pregnancy were not well-known.

What are the main findings? Response: Progesterone hormone is known to be essential to maintain a pregnancy. Researchers and clinicians have debated for over 50 years whether progesterone supplementation in women with early pregnancy bleeding could rescue a pregnancy from miscarrying. There were some clinical studies suggesting progesterone could be useful, but the studies were of poor quality and small, so we could not be certain. So the current study, called the PRISM trial, was conducted using very sound methods and on a large population of women, in fact over 4000 women in the UK, to produce a definitive answer to this question. Overall, there were more babies in the group of women given progesterone compared with the group of women given the dummy placebo tablets, but there was statistical uncertainty in this finding. However, when we looked at the sub-population of women who were at high risk of miscarriage because of not only bleeding in early pregnancy but also having a history of previous miscarriage, we found progesterone was shown to have clear benefit. This is a hugely important finding as there is now a treatment option to women with early pregnancy bleeding and a history of previous miscarriages.

MedicalResearch.com Interview with: [caption id="attachment_48399" align="alignleft" width="128"]Dr. Angela Lupattelli, PhDSchool of PharmacyUniversity of Oslo Dr. Lupattelli[/caption] Dr. Angela Lupattelli, PhD School of Pharmacy University of Oslo MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Between 1-4% of pregnant women take at least once a benzodiazepine and/or a z-hypnotic medication during the course of gestation. These medications are generally used intermittently in pregnancy, mainly for treatment of anxiety disorders and sleeping problems, which are not uncommon conditions among pregnant women. However, data regarding the safety of benzodiazepine and/or a z-hypnotic in pregnancy on child longer-term development are sparse. For instance, studies on child motor skills are only available up to toddler age, and little is known in relation to other child developmental domains. So, there is an urgent need to better understand whether prenatal use of benzodiazepine and/or a z-hypnotic medication may pose detrimental longer-term child risks.

Metformin passes the placenta, and the fetus is thus exposed to the drug. Although no teratogenicity has been reported, metformin might have long-term effects on offspring health. This study is a follow-up of cardiometabolic risk factors of 141 5- to 10-year-old children born in the PregMet study. This study was a double-blind, randomized controlled trial (RCT) designed to test the hypothesis that metformin given throughout pregnancy reduces the prevalence of pregnancy complications that are associated with the common endocrine disorder PCOS. Pregnant women with PCOS were randomized to receive metformin or placebo throughout pregnancy.

What are the main findings? Response: Alongside increasingly permissive marijuana use attitudes and laws, the prevalence of marijuana use among pregnant mothers has increased substantially (by 75% between 2002 and 2016), with some evidence that pregnant women may be using cannabis to combat pregnancy-related nausea. Our data came from the Adolescent Brain Cognitive Development (ABCD) Study, which included over 4,000 subjects with data on maternal marijuana use during pregnancy. Our main finding was that the children of mothers who used marijuana after learning they were pregnant had a small but significant increase in risk for psychosis in their future.

Response: Miscarriage is a prevalent health concern, with one in five pregnancies ending in miscarriage, which is a pregnancy loss before 20 weeks’ gestation. Past research has shown that women who have miscarried often suffer mental health effects such as heightened grief, depression, loneliness, and suicidality. Although much of the research on coping with miscarriage has focused on women’s health, many miscarriages occur within romantic relationships and affect the non-miscarrying partner as well. Women in heterosexual marriages report that their husband is often their top support-provider. Past research has shown that husbands suffer with mental health effects after a miscarriage, sometimes for even longer than their wives, but are not often supported in their grief because miscarriage is a “woman’s issue” and they feel uncomfortable talking about it.

Author Interviews, Fertility, OBGYNE / 19.03.2019

MedicalResearch.com Interview with: Prof. Daniel R Brison PhD, FRCPath Scientific Director Department of Reproductive Medicine Manchester University NHS Foundation Trust Old St. Mary's Hospital Manchester U.K and Catherine M Castillo PhD Maternal & Fetal Health Research Centre Division of Developmental Biology and Medicine School of Medical Sciences, Faculty of Biology, Medicine and Health The University of Manchester  MedicalResearch.com: What is the background for this study? What are the main findings? Response: IVF conceived children have been known to have poorer birth outcomes when compared to spontaneously conceived children. Even when excluding twins and triplets, which result from more complicated pregnancies, IVF singletons have an increased risk of low birth weight and being born small for “dates” (length of gestation).  This is important as studies carried out in non-IVF children show that low birth weight is associated with slightly higher risk of disease in later life. We knew from the literature that birth outcomes differed within the IVF population depending on the type of treatment used; for example, singletons conceived from frozen/thawed embryos are born with higher average birth weights when compared to their fresh embryo conceived counterparts. Our research team wanted to investigate whether IVF practices and technologies per se (which have advanced quite rapidly over the years since 1978 when the first IVF baby was conceived) were associated with differences in singleton birth weight. In attempting to quantify historical changes in laboratory practice going back as far as we could, we discovered that our outcome of interest – birth weight – had indeed increased notably throughout the time period covered by the available data. Besides observing an increase in birth weight of almost 180g over the study period (when accounting for child gender, gestational age and maternal parity), we also observed that frozen embryo transfer was associated with higher birth weight, and spontaneous fetal reduction and longer duration of infertility were associated with lower average birth weight.

What are the main findings? Response: There has been a global surge in vitamin D deficiency happening in parallel with an increase in prevalence of childhood asthma, which suggests that low maternal vitamin D levels during pregnancy may increase asthma risk in the child. Due to that we conducted a randomized double-blinded controlled trial within the Danish COPSAC2010 cohort (www.copsac.com) of 7-fold (2,800 IU/d) vs. standard dose (400 IU/d) of vitamin D supplementation from pregnancy week 24 aiming to reduce offspring asthma risk. At age 3, we observed a non-significant 24% reduced risk of recurrent asthma-like symptoms, ie. recurrent wheeze, in the high-dose vitamin D group. In the current study, we followed 545 of the 581 children in the study till age 6, where an asthma diagnosis can be established and observed no effect of the high-dose vitamin D supplement on the child's risk of asthma.

What are the main findings? Response: Yeast infections are common during pregnancy (10%). Although topical treatments are first-line therapies, yeast infections during gestation are often more severe and are resistant to topical options. Hence, low dose oral fluconazole is often the treatment of choice for pregnant women (1 dose for 1 day). Human and animal studies have shown that high dose of fluconazole is teratogenic.Few studies are available for the risk associated with low dose of fluconazole (the most used during pregnancy). Also, no one has studied the combined effect of low- and high-dose fluconazole use during pregnancy on overall adverse pregnancy outcomes (spontaneous abortions, stillbirths and major malformations).

Giussani PhD ScD FRCOG Professor of Developmental Cardiovascular Physiology & Medicine Department of Physiology Development & Neuroscience University of Cambridge Director of Studies in Medicine College Lectureship in Medicine '1958' Gonville & Caius College UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: Heart disease kills 1 in 3 people worldwide.  When we hear about heart disease, the first thing we think of is a gene-environent interaction.  That is to say, how our genes interact with traditional lifestyle factors, such as smoking, obesity and/or a sedentary lifestyle to promote an increased risk of cardiovascular disease.  However,  it has also become established that the gene-environment interaction early in life may be just as, if not more, important in ‘programming’ future heart health and heart disease. That is to say, how the quality of the intrauterine environment in which we develop may also shape our future heart risk.  Evidence from human sibling-pair studies suggests that these relationships are causal, that they occur independently of genotype and that they are significantly influenced by the quality of the intrauterine environment during pregnancy.  For instance, bariatric surgery to decrease the weight of obese women reduced the risk of obesity, insulin resistance and raised blood pressure in children born after surgery compared to those born before. Therefore, these studies highlight a disproportionate risk of disease in offspring born from the same mother but under different in utero conditions, providing strong evidence in humans that the environment experienced during this critical period of development directly influences long-term cardiovascular health. One of the most common outcomes of complicated pregnancy in humans is chronic fetal hypoxia, as can occur during placental insufficiency or preeclampsia. The main findings of our study show that prenatal hypoxia can programme future heart disease in the offspring and that maternal treatment with the antioxidant vitamin C can be protective (see paper attached).
Author Interviews, Breast Cancer, NIH, OBGYNE / 27.12.2018

MedicalResearch.com Interview with: [caption id="attachment_46711" align="alignleft" width="133"]Dale P. Sandler, Ph.D. Chief, Epidemiology Branch National Institute of Environmental Health Sciences NIH Dr. Sandler[/caption] Dale P. Sandler, Ph.D. Chief, Epidemiology Branch National Institute of Environmental Health Sciences NIH MedicalResearch.com: What is the background for this study? Response: Not having children is a well-established risk factor for breast cancer, but most of this evidence comes from studies of postmenopausal women since breast cancer before menopause is relatively uncommon. There is growing evidence that some risk factors differ for premenopausal and postmenopausal breast cancer – for example obesity which increases risk for breast cancer after menopause but appears to be protective before menopause. There was some evidence that breast cancer risk increased shortly after pregnancy. It was thought that this risk lasted for 5 to ten years. Studies were unable to fully characterize the duration of this increase in risk or evaluate factors such as breast feeding, age at birth, or family history of breast cancer that could modify the relationship between recent pregnancy and breast cancer risk. Breast cancer before menopause or age 55 is relatively rare, and few individual studies are large enough to answer these questions. To answer these questions, we formed the Breast Cancer Collaborative Group, a pooling project involving 20 prospective cohort studies. We included 890,000 women from 15 of these long-term studies across three continents, including over 18,000 incident breast cancer cases.

What are the main findings?  Response: The background of this study is that there is increasing recognition of the longer-term health and social outcomes associated with preterm birth such as independent living, quality of life, self-perception and socioeconomic achievements. However, much less is known about differences in education and income among adults born at different gestational weeks in the term period. In this study shorter gestational duration, even within the term range, was associated with lower chances of having a high personal income and having completed a secondary or tertiary education at age 28 years. This is the first study to show that adults born at 37 and 38 completed weeks of gestation had slightly lower chances of having a high income and educational level than adults born at 40 completed weeks of gestation.

Huybrechts, MS PhD Associate Professor of Medicine Brigham and Women’s Hospital Harvard Medical School Boston, MA 02120  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Pregnant women often experience nausea and vomiting, particularly during the first trimester.  Early treatment is recommended to relieve symptoms and prevent progression to hyperemesis gravidarum.  Although not formally approved for this indication, ondansetron is the most frequently prescribed treatment for nausea and vomiting in pregnancy in the US: 22% of pregnant women reportedly used ondansetron in the US in 2014. Despite this common use, the available evidence on the fetal safety of ondansetron is limited and conflicting, and the possibility of a doubling in risk of cleft palate and cardiac malformations has been raised. We therefore evaluated the association between ondansetron exposure during the first trimester of pregnancy, the period of organogenesis, and the risk of congenital malformations in a cohort of 1,816,414,publicly insured pregnancies using the nationwide Medicaid Analytic eXtract data for 2000-2013.  A total of 88,467 women (4.9%) were exposed to ondansetron during the first trimester.  After adjusting for a broad range of potential confounding variables, we found no association with cardiac malformations (RR = 0.99; 95% CI, 0.93 – 1.06)  and congenital malformations overall (RR = 1.01; 95% CI, 0.98 – 1.05). For oral clefts, we found a 24% increase in risk (RR=1.24; 95% CI, 1.03 – 1.48), which corresponds to an absolute risk of 2.7 per 10,000 births (95% CI, 0.2 – 5.2 per 10,000 births).  These findings were consistent across sensitivity analyses, conducted to address potential misclassification and confounding bias.
