MedicalResearch.com Interview with: Cuilin Zhang MD, PhD Senior Investigator, Epidemiology Branch Division of Intramural Population Health Research NICHD/National Institutes of Health Bethesda, MD 20817  MedicalResearch.com: What is the background for this study? Response: Refined grains with a high glycemic index and reduced fiber and nutrient content have been linked to increased adiposity and higher risk of metabolic syndrome among adults. Despite these differences and the growing body of literature on the link between maternal diet/nutrition during pregnancy and subsequent offspring health consequences throughout the lifespan, little is known about the intergenerational impact of refined-grain intake during pregnancy on long-term cardio-metabolic outcomes in the offspring.

Author Interviews, Depression, OBGYNE, Pharmacology / 19.06.2017

MedicalResearch.com Interview with: Samantha Meltzer-Brody, MD, MPH Associate Professor and Associate Chair for Faculty Development Director, Perinatal Psychiatry Program Director, Taking Care of Our Own Program Department of Psychiatry Chapel Hill, NC 2759  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The Lancet published results from a randomized, placebo-controlled, phase 2 clinical trial with the investigational medication, brexanolone, for women with severe postpartum depression (PPD). During the study, which was conducted at multiple sites across the country, physician researchers administered brexanolone in 21 women, 10 of whom were administered a 60-hour infusion of brexanolone. The other 11 women were given a placebo. Results from the trial showed that 70 percent of participants who received the drug saw remission of their PPD symptoms within 60 hours of treatment, an effect that was maintained until the 30-day follow up.

MedicalResearch.com Interview with: Prof. Dr. João Martins Pisco MD PhD Radiologia de Intervenção Hospital Saint Louis - Rua Luz Soriano PortugalProf. Dr. João Martins Pisco MD PhD Radiologia de Intervenção Hospital Saint Louis - Rua Luz Soriano Portugal MedicalResearch.com: What is the background for this study? What are the main findings? Response: The background for the study is the good results I started to check in patients with uterine fibroids who could conceive a successful pregnancy with live birth following embolization. MedicalResearch.com: What should readers take away from your report? Response: The readers should know that fertility can be restored following embolization of uterine fibroids, particularly if the embolization is partial. The wish of conception in patients with uterine fibroids is not a contraindication for fibroids embolization. (more…)
Author Interviews, JAMA, Lifestyle & Health, OBGYNE, Weight Research / 07.06.2017

MedicalResearch.com Interview with:   Professor Helena Teede MBBS, FRACP, PhD Executive Director Monash Partners Academic Health Research Translation Centre Director Monash Centre for Health Research and Implementation Monash University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Reproductive aged women are gaining weight rapidly both before and during pregnancy. Here in 1.3 million pregnancies internationally we show that almost 3 in 4 have unhealthy weight gain (half with excess weight gain and one quarter with inadequate gain) MedicalResearch.com: What should readers take away from your report? Response: For women establish your healthy weight for your height and try to stay within this for better fertility, pregnancy and for your and your child's health. Regardless of your starting weigh,  aim to gain within targets in pregnancy. Seek help to do so. For health professionals: unhealthy weight gain in pregnancy is now the norm, we must monitor women in pregnancy wand support them to gain healthy weight for better health outcomes. Weighing is not enough with health professionals needing skills in healthy conversations and support strategies for women. For governments and policy makers this life stage around pregnancy is an optimal time to tackle obesity prevention and is targeted by WHO. (more…)
Author Interviews, CMAJ, OBGYNE / 05.06.2017

MedicalResearch.com Interview with: Giulia Muraca, MPH, PhD(c) Vanier Canada Graduate Scholar School of Population and Public Health Child & Family Research Institute Faculty of Medicine University of British Columbia  MedicalResearch.com: What is the background for this study? Response: The rate of cesarean delivery has increased dramatically over the last 30 years. And in an effort to curb the rising trend in caesarean delivery, The American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine have recently advocated for increased use of operative vaginal delivery (forceps/vacuum delivery) as a strategy to reduce the cesarean delivery rate. The evaluation of approaches to achieve this end are underway and the current discourse surrounding operative vaginal delivery centers on methods to promote these important skills. But, the truth is, we don’t yet fully understand the balance of risks and benefits to mothers and their babies following operative vaginal delivery compared with caesarean delivery. The preferred choice given these two options relies heavily on how far the baby’s head has descended in the birth canal. If the baby’s head has descended far enough that it is visible and on the perineum, then the use of an instrument has clear advantage. However, when the fetal head is engaged in the maternal pelvis, but has not descended so far down the birth canal, the decision between these modes of delivery becomes much less clear. These deliveries are called midpelvic deliveries. And it’s an increase in these midpelvic deliveries that would have the most potential as a strategy to reduce the cesarean delivery rate, and as a result, it is these deliveries that we were interested in studying. Operative vaginal deliveries are carried out in approximately 14% of all term births in Canada and those that occur when the baby is at midpelvic station account for over 20% of all operative vaginal deliveries. This translates to about 2-3% of all term, singleton deliveries in Canada or about 10,000 deliveries per year overall. The literature on perinatal and maternal outcomes contrasting midpelvic operative vaginal delivery and caesarean delivery is based on studies undertaken 25 to 30 years ago that are no longer reflective of the current obstetric practice.  This was the impetus for our study. We reasoned that before we decide to encourage increased OVD we should first get a sense of the safety of such procedures compared to cesarean delivery as provided by contemporary maternity care providers.

Author Interviews, CDC, Flu - Influenza, OBGYNE, Vaccine Studies / 31.05.2017

MedicalResearch.com Interview with: Dr. Elyse Olshen Kharbanda, MD MPH HealthPartners Institute Minneapolis, MN MedicalResearch.com: What is the background for this study? What are the main findings? Response: Pregnant women who get the flu are at an increased risk for severe illness. To protect pregnant women, the Advisory Committee on Immunization Practices recommends women receive inactivated influenza vaccine (IIV) during any trimester of their pregnancy. This study used data from the Vaccine Safety Datalink to evaluate if there was an increased risk for selected major structural birth defects for infants whose mothers received IIV in the first trimester of pregnancy versus infants who were unexposed to IIV. Among over 425,000 live births, including 52,856 whose mothers received IIV during first trimester, we evaluated risks for major structural birth defects.  In this large observational study, we did not observe increased risks for major structural birth defects in offspring following first trimester maternal inactivated influenza vaccine exposure.

Author Interviews, OBGYNE, PLoS / 31.05.2017

MedicalResearch.com Interview with: Sarka Lisonkova, MD, PhD Assistant Professor, Department of Obstetrics and Gynaecology, University of British Columbia. Children’s and Women’s Health Centre MedicalResearch.com: What is the background for this study? What are the main findings? Response: Adverse fetal and infant outcomes associated with maternal age were known and our study confirms that the risk of fetal and neonatal death and severe neonatal morbidity increases among mothers over 30 years. We also knew that older mothers are more likely to have hypertension, diabetes, and other chronic diseases, and they are more likely to develop gestational diabetes, hypertension during pregnancy, and preeclampsia. These complications may put the fetus or newborn at risk, but are generally not considered to be potentially life threatening to the mother. Our study adds new information on the rates of severe maternal morbidities that have a high case-fatality rate, lead to organ damage, or have serious health implications such as hysterectomy. Our study also adds the information on the rates of any severe adverse birth outcome - for baby or mom - in the association with maternal age, which is important for counseling. Women usually want to know ‘what are the chances that anything bad happens’. (more…)
AHA Journals, Author Interviews, Blood Pressure - Hypertension, OBGYNE, Stroke / 27.05.2017

MedicalResearch.com Interview with: Eliza Miller, M.D. Vascular neurology fellow New York-Presbyterian Hospital/Columbia University Medical Center New York City  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Preeclampsia is a common disorder that causes high blood pressure during pregnancy. It affects about 1 in 20 pregnant women. Women with preeclampsia are at higher risk for stroke during pregnancy and post-partum, but it’s very difficult to predict who is going to have a stroke. Our study looked at a large dataset of billing data from New York State, and compared women who had preeclampsia and strokes to women who had preeclampsia but did not have a stroke. We found that preeclamptic women with urinary tract infections, bleeding or clotting disorders, or preexisting high blood pressure were at higher risk of having strokes during pregnancy or postpartum.

MedicalResearch.com Interview with: Hirohito Ichii, M.D, Ph.D, FACS Associate Professor of Clinical Surgery Division of Transplantation, Department of Surgery University of California, Irvine, Orange CA 92868 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Venous thromboembolism (VTE) is a critical complication after surgery. Although pregnancy is known to increase the risk of VTE 4- to 5-fold, there are scarce data on the risk of VTE among pregnant women who are undergoing surgery. In this study using the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) data, we observed that pregnant women, compared to matched non-pregnant women, experienced 93% higher likelihood of developing VTE. Absolute incidence of VTE among pregnant vs. matched non-pregnant were 0.5% vs. 0.3%. (more…)
Author Interviews, NEJM, OBGYNE, Yale / 21.05.2017

MedicalResearch.com Interview with: Hugh S. Taylor, M.D. Anitta O’keeffe Young Professor and Chair Departemnt of Obstetrics, Gynecology and Reproductive Sciences Yale School of Medicine Chief of Obstetrics and Gynecology Yale-New Haven Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: Elagolix is an investigational, oral gonadotropin-releasing hormone (GnRH) receptor antagonist that blocks endogenous GnRH signaling by binding competitively to GnRH receptors. Administration results in rapid, reversible, dose-dependent inhibition of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) secretion, leading to reduced ovarian production of the sex hormones, estradiol and progesterone, while on therapy. Data from two replicate Phase 3 studies evaluating the efficacy and safety of elagolix were published in the New England Journal of Medicine. Elagolix demonstrated dose-dependent superiority in reducing daily menstrual and non-menstrual pelvic pain associated with endometriosis compared to placebo. At month three and month six, patients treated with elagolix reported statistically significant reductions in scores for menstrual pain (dysmenorrhea, DYS) and non-menstrual pelvic pain (NMPP) associated with endometriosis as measured by the Daily Assessment of Endometriosis Pain scale. The safety profile of elagolix was consistent across both Phase 3 trials and also consistent with prior elagolix studies. Ultimately, the studies showed that both elagolix doses (150 mg QD and 200 mg BID) were effective in improving dysmenorrhea, non-menstrual pelvic pain and quality of life over 6 months in women with endometriosis-associated pain. The elagolix safety/tolerability profile was consistent with the mechanism of action. (more…)
Author Interviews, OBGYNE, Telemedicine / 20.05.2017

MedicalResearch.com Interview with: Abigail R.A. Aiken, MD, MPH, PhD Assistant Professor LBJ School of Public Affairs Faculty Associate Population Research Center University of Texas at Austin Austin, TX, 78713Abigail R.A. Aiken, MD, MPH, PhD Assistant Professor LBJ School of Public Affairs Faculty Associate Population Research Center University of Texas at Austin Austin, TX, 78713 MedicalResearch.com: What is the background for this study? What are the main findings? Response: We've known for some time that women in Ireland and Northern Ireland self-source their own abortions using online telemedicine. In fact, this model has revolutionized abortion access for Irish women. Yet very little was previously known about the outcomes of those abortions. How safe and effective are they? We wanted to address that knowledge gap with this study. What this research shows is that self-sourced medication abortion, conducted entirely outside the formal healthcare setting, can have high rates of effectiveness and low rates of adverse outcomes. Women can successfully manage their own abortions and recognize the symptoms of potential complications. Among the small number who experienced such a symptom, virtually all sought in-person medical attention as advised. (more…)
Author Interviews, Dermatology, OBGYNE / 16.05.2017

MedicalResearch.com Interview with: Alexander Egeberg, MD PhD Gentofte Hospital Department of Dermatology and Allergy Denmark MedicalResearch.com: What is the background for this study? What are the main findings? Response: An issue that frequently arise in clinical practice is the question from patients whether they should discontinue their therapy if they want to have children. Since immunosuppressant agents are frequently used for a number of conditions, and discontinuation could lead to disease flaring, assessment of the potential impact of such drugs on birth outcomes is important. In our study, we examined birth outcomes in children whose father had received treatment with methotrexate, azathioprine, cyclosporine, and mycophenolate mofetil in the time leading up to conception. Importantly, we found no increased risk of congenital abnormalities, low birth weight, or preterm birth associated with paternal treatment with these drugs. (more…)
Author Interviews, CMAJ, Diabetes, OBGYNE / 15.05.2017

MedicalResearch.com Interview with: Dr. Gillian Booth PhD Researcher at St. Michael's and the Institute for Clinical Evaluative Sciences (ICES) MedicalResearch.com: What is the background for this study? What are the main findings? Response: The impact of climate change on health is becoming increasingly relevant given the rise in global air temperature, and there is growing evidence supporting a link between air temperature, metabolic function, and energy expenditure. We know from animal models and small studies in humans that cold exposure and activate a type of fat known as brown fat and it appears that this process can improve sensitivity to insulin. However no studies have yet looked at air temperature and the development of diabetes. So we decided to examine the relationship between outdoor air temperature and gestational diabetes – a temporary form of diabetes that arises in the second trimester of pregnancy. (more…)
Author Interviews, CMAJ, Fertility, Karolinski Institute, OBGYNE / 08.05.2017

MedicalResearch.com Interview with: Neda Razaz, PhD, MPH Postdoctoral Fellow Reproductive Epidemiology Unit Karolinska Institutet MedicalResearch.com: What is the background for this study? What are the main findings? Response: Multiple births of twins and triplets – and the associated health risks – have increased in many high-income countries, with a respective two-fold and three-fold increase in recent decades. In Canada, triplet births or higher have increased from 52.2 per 100 000 live births to 83.5 between 1991 and 2009, mainly because of an increase in fertility treatments for older women of child-bearing age. In this study we found that among twin and triplet pregnancies that were reduced to singleton or twin pregnancies, there was a substantial reduction in complications such as preterm birth and very preterm birth. Although rates of death and serious illness were not lower among all multifetal pregnancies that were reduced, pregnancies that resulted from fertility treatments did show a significant reduction in rates of death or serious illness following fetal reduction.

Aging, Author Interviews, Cancer Research, CDC, OBGYNE / 03.05.2017

MedicalResearch.com Interview with: Mary C. White, ScD Epidemiology and Applied Research Branch Division of Cancer Prevention and Control, CDC Atlanta GA 30341 MedicalResearch.com: What is the background for this study? Response: For women between the ages of 21 to 65, Pap testing every three years, or Pap testing with HPV co-testing every five years, can prevent cervical cancers and deaths. Current recommendations state that women 65 and older and not otherwise at special risk can skip Pap tests, but only if they have had three consecutive negative Pap screening tests or two consecutive negative co-tests over the past 10 years, with the most recent done within the past five years. We used data from two federal cancer registry programs to examine how cervical cancer risk changes with age, after excluding women who have had a hysterectomy. We also examined data from a federal national health survey to examine the proportion of women who either had never been tested or had not been tested in the last 5 years. (more…)

MedicalResearch.com Interview with: Anick Bérard PhD FISPE Research chair FRQS on Medications and Pregnancy Director, Réseau Québécois de recherche sur le médicament (RQRM) Professor, Research Chair on Medications, Pregnancy and Lactation Faculty of Pharmacy, University of Montreal Director, Research Unit on Medications and Pregnancy Research Center, CHU Ste-Justine MedicalResearch.com: The Danish study you cite reported a connection between antibiotics and miscarriage – why was further research of this topic necessary? Response: Given that a single study will assess an association, repetition of findings are essential in order to assess causality. For example, we were able to conclude that smoking was causing lung cancer after 10 years of observational research on the topic showing concordant associations. In addition, antibiotic prescription patterns vary from country to country, hence the importance of studying the research question in various patient populations. Finally, our cohort has validated exposure status, gestational age (first day of pregnancy) and miscarriage cases - our study was also able to look at types of antibiotics. (more…)
Author Interviews, Environmental Risks, OBGYNE, Pediatrics / 03.05.2017

MedicalResearch.com Interview with: Laura Birks, MPH, Predoctoral Fellow ISGlobal Instituto de Salud Global de Barcelona - Campus MAR Barcelona Biomedical Research Park (PRBB) (office 183.01B) Barcelona, Spain MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previous studies in Denmark and the Netherlands have reported associations between prenatal cell phone use and child behavioral problems, but findings have been inconsistent and based on retrospective assessment of cell phone use. This study aimed to assess this association in a multi-national analysis, using data from three cohorts with prospective data on prenatal cell phone use, together with previously published data from two cohorts with retrospectively collected cell phone use data. We found that cell phone use during pregnancy was associated with increased risk for behavioral problems in offspring, specifically hyperactivity/inattention problems. This association was fairly consistent across cohorts and between cohorts with retrospectively and prospectively collected cell phone use data. While our models were adjusted for many confounders, it is possible that other factors could explain this association, such as hyperactivity in the mother or parenting styles (variables that were not collected in these cohorts). Furthermore, to date there is no known biological mechanism that could explain the association. (more…)
Author Interviews, Blood Pressure - Hypertension, JAMA, OBGYNE / 01.05.2017

MedicalResearch.com Interview with: Dr. Maureen Phipps, USPTS Task Force member Department chair and Chace-Joukowsky professor of obstetrics and gynecology Assistant dean for teaching and research on women's health Warren Alpert Medical School of Brown University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Preeclampsia, which includes high blood pressure after 20 weeks of pregnancy, is one of the most serious health problems affecting pregnant women. After reviewing the evidence, the Task Force found the benefits of screening for preeclampsia outweighed the harms and recommended screening pregnant women for preeclampsia with blood pressure measurements throughout pregnancy. The evidence showed mothers and their babies are likely to benefit from screening, as screening leads to treatment that reduces their risk of severe complications, including death. (more…)
Author Interviews, Menopause, OBGYNE / 01.05.2017

MedicalResearch.com Interview with: Dr. James A. Simon, MD CCD, NCMP, FACOG Clinical professor of obstetrics and gynecology George Washington University, and Medical director, Women's Health & Research Consultants® Washington, D.C MedicalResearch.com: What is the background for this study? Response: The Phase 2b uterine fibroids study was a 24-week, multicenter, double-blind, randomized, placebo-controlled, parallel group clinical trial that evaluated the efficacy and safety of elagolix alone or in combination with add-back therapy (estradiol/norethindrone acetate) in women with heavy uterine bleeding associated with uterine fibroids. Elagolix is currently being investigated in diseases that are mediated by sex hormones, such as uterine fibroids and endometriosis. The study was conducted in 567 premenopausal women, age 18 to 51, at 100 sites in the United States, Canada, Puerto Rico, Chile and the United Kingdom. The two cohort design study evaluated the safety and efficacy of two elagolix treatment regimens (300mg BID and 600mg QD) alone and in combination with two different strengths of add-back therapy (estradiol/norethindrone acetate). The data presented were results from the 300mg cohort. Results from the 600mg cohort were similar and will be reported in a future publication. Current non-surgical treatments indicated for uterine fibroids are limited, and women suffering from heavy menstrual bleeding associated with uterine fibroids need more options. (more…)
Author Interviews, CDC, OBGYNE, Pediatrics / 01.05.2017

MedicalResearch.com Interview with: Deborah L. Dee, PhD Division of Reproductive Health National Center for Chronic Disease Prevention and Health Promotion CDC MedicalResearch.com: What is the background for this study? Response: Although the national teen birth rate has dropped to a historic low (22.3 births per 1,000 females aged 15-19 years in 2015), many teens continue to have repeat births. Because repeat teen births are more likely than first teen births to be preterm and low birth weight, and giving birth more than once as a teenager can significantly limit a mother’s ability to attend school and obtain work experience, it’s important to assess patterns in repeat teen births and better understand contraceptive use within this population.

Author Interviews, Autism, Depression, JAMA, OBGYNE, Pediatrics / 19.04.2017

MedicalResearch.com Interview with: Simone Vigod, MD, MSc, FRCPC Psychiatrist and Lead, Reproductive Life Stages Program Women’s Mental Health Program Women’s College Hospital Toronto, ON MedicalResearch.com: What is the background for this study? What are the main findings? Response: Depression is one of the most common problems that can complicate a pregnancy. Untreated, or incompletely treated, it can be associated with significant harm to mother and child. While psychotherapies alone may be effective for women with mild (or even moderate) severity symptoms, sometimes antidepressant medication is required. In these cases, the benefits of treatment must be weighed against potential risks. Previous research suggested that there may be an increased risk for autism in children exposed to antidepressant medication during pregnancy. However, previous studies were limited in their ability to account for other potential causes of autism in their analyses. In our study, we used several different strategies to try to compare children whose pregnancy exposures were very similar, except for exposure to an antidepressant. The main finding was that after using these strategies, there was no longer a statistically significant association between in-utero antidepressant exposure and autism. (more…)

MedicalResearch.com Interview with: Florence Gressier MD PhD Insermk Department of psychiatry CHU de Bicêtrem Le Kremlin Bicêtre France MedicalResearch.com: What is the background for this study? What are the main findings? Response: Results from recent studies have suggested an increased risk for Autism Spectrum Disorders (ASDs) in children exposed to antidepressants in utero. We performed a systematic review of and a meta-analysis of published studies to assess the association between ASDs and fetal exposure to antidepressants during pregnancy for each trimester of pregnancy and preconception. Our systematic review and meta-analysis suggests a significant association between increased ASD risk and maternal use of antidepressants during pregnancy; however, it appears to be more consistent during the preconception period than during each trimester. In addition, the association was weaker when controlled for past maternal mental illness. Maternal psychiatric disorders in treatment before pregnancy rather than antenatal exposure to antidepressants could have a major role in the risk for Autism Spectrum Disorders. (more…)
Author Interviews, Epilepsy, JAMA, Karolinski Institute, OBGYNE, Pediatrics, Weight Research / 06.04.2017

MedicalResearch.com Interview with: Neda Razaz-Vandyke, PhD, MPH Postdoctoral Fellow Reproductive Epidemiology Unit Karolinska Institutet   MedicalResearch.com: What is the background for this study? What are the main findings? Response:   There is a growing concern about long-term neurological effects of prenatal exposure to maternal overweight and obesity. The etiology of epilepsy is poorly understood and in more than 60% of cases no definitive cause can be determined. We found that maternal overweight and obesity increased the risks of childhood epilepsy in a dose-response pattern. (more…)

MedicalResearch.com Interview with: Hans Bisgaard, MD, DMSc Professor of Pediatrics The Faculty of Health Sciences University of Copenhagen Copenhagen University Hospital, Gentofte Copenhagen, Denmark MedicalResearch.com: What is the background for this study? Response: The consumption of antibiotics is increasing worldwide. Antibiotics alter the maternal bacterial colonization and by vertical transmission this can affect the offspring. An unfavorable microbiome may increase the disease propensity of the offspring. Otitis media is one of the most common infections in early childhood. We hypothesized that antibiotic consumption in pregnancy can increase the children’s risk of otitis media. (more…)

MedicalResearch.com Interview with: Alain Chedotal, PhD Group Leader, Institut de la Vision (Inserm/UPMC/CNRS), Paris and Sylvain Berlemont, PhD CEO & Founder of Keen Eye Technologies, Incubateur Institut de la Vision, Paris MedicalResearch.com: What is the background for this study? What are the main findings? Response: What was known about human embryo development was based on histological techniques developed at the beginning of the twentieth century and no significant progress had been made for about fifty years. A few years ago our team found a method allowing to perform immunostaining on whole-mouse embryos and adult mouse brains. Complete 3D images of the intact samples could be obtained after they were cleared with solvents and imaged with a light sheet microscope. In this new study we have adapted this method to human embryos during the first trimester of gestation. We provide for the first time high-resolution 3D images of the developing peripheral nervous, muscular, vascular, cardiopulmonary, and urogenital systems. We found evidence for important in differences in the embryonic pattern of nerve branches between the right and left hands. We also present evidence for a differential vascularization of the male and female genital tracts concomitant with sex determination. (more…)

MedicalResearch.com Interview with: Alex J. Polotsky, MD Associate Professor of Obstetrics and Gynecology University of Colorado Denver Practice homepage MedicalResearch.com: What is the background for this study? What are the main findings? Response: It has been well established that profound dietary changes occurred over the past 100 years. The type and amount of fat consumed has changed quite a bit over the course of 20th century. Intake of omega-3 polyunsaturated fatty acids (PUFAs), previously consumed in large quantities by humans from vegetable and fish sources, has dropped significantly. The typical Western diet (sometimes also called the typical American diet) provides an omega-6 to omega-3 fatty acid ratio of as high as 25:1, which is quite different from what it used to up until about the 19th century (believed to be about 1:1 ratio). In animal studies, diets enriched with omega-3 PUFA enhance early embryonic development and boost progesterone secretion. Obesity is well known to be associated with decreased progesterone production in women (even if a obese woman ovulates). The reasons for this are not clear. Obesity is also a state of low-grade chronic inflammation. Omega-3 fatty acids are well known to have anti-inflammatory properties. We sought to test whether dietary supplementation with omega-3 PUFA favorably affects reproductive hormones in women and whether this effect includes normalization of progesterone production in obesity. All women in the study tolerated supplementation well, and had significantly decreased their omega-6 to omega-3 ratios (they were normalized much closer to a 1:1 ratio). Omega-3 supplementation resulted in a trend for increased progesterone in obese women, thus enhancing ovulatory function. A 16 to 22 percent increase was observed. Additionally, the supplementation resulted in reduced systemic inflammation. (more…)

MedicalResearch.com Interview with: Anders Hviid Senior Investigator, M.Sc.,Dr.Med.Sci. Department of Epidemiology Research Division of National Health Surveillance & Research MedicalResearch.com: What is the background for this study? Response: HPV vaccination targeting girls and young women has been introduced in many countries throughout the world. HPV vaccines are not recommended for use in pregnancy, but given the target group, inadvertent exposure will occur in early unrecognized pregnancies. However, data on the safety of HPV vaccination in pregnancy is lacking. (more…)
Author Interviews, Cost of Health Care, Fertility, OBGYNE / 29.03.2017

MedicalResearch.com Interview with: Emily S. Jungheim, MD, MSCI Assistant Professor, Obstetrics and Gynecology Division of Reproductive Endocrinology and Infertility Washington University St. Louis, Missouri MedicalResearch.com: What is the background for this study? What are the main findings? Response: Many women with health insurance lack coverage for fertility treatment so they end up being self-pay for fertility treatments which can be expensive and limit access to care. 15 states have responded with mandates for employers to include fertility coverage in their employee insurance benefits, and 5 of these have comprehensive mandates that include IVF. Illinois is one of these states. Washington University is located on the border between Illinois and Missouri so our fertility center treats a number of women with coverage for fertility treatment and a large number of women who are self-pay for fertility treatment. We suspected that women requiring IVF to conceive were more likely to follow through with treatments if they had coverage so we decided to look at our data. Ultimately we confirmed our suspicions. Women with coverage were more likely to come back for additional cycles of IVF if they didn't conceive. Ultimately this ability to come back for additional treatment cycles led to a higher chance of live birth. (more…)
Author Interviews, Cancer Research, JAMA, OBGYNE, Pediatrics / 27.03.2017

MedicalResearch.com Interview with: Hazel B. Nichols, PhD, UNC Assistant professor Lineberger Comprehensive Cancer Center member UNC Gillings School of Global Public Health. MedicalResearch.com: What is the background for this study? Response: Each year more than 45,000 adolescent and young adult women (AYA, ages 15-39 years) are diagnosed with cancer in the United States. While many of these women may wish to have children in the years following diagnosis, there is currently little information available to address their concerns about the impact of cancer diagnosis and treatment on future pregnancy. We identified >2,500 women who had a child after their cancer diagnosis using data from the North Carolina Central Cancer registry and statewide birth certificate files. We investigated whether adverse birth outcomes, such as preterm birth and low birth weight, were more common among AYA cancer survivors compared to women without cancer. We also looked at infant Apgar scores, which measure newborn health, and a calculation called small-for-gestational age, which can indicate restricted growth during pregnancy. (more…)
