Author Interviews, Diabetes, JAMA, OBGYNE / 12.09.2018

MedicalResearch.com Interview with: Boyd E Metzger, MD Professor Emeritus of Medicine (Endocrinology) Feinberg School of Medicine Northwestern University MedicalResearch.com: What is the background for this study? Response: The Hyperglycemia and Adverse Pregnancy Outcome (HAPO) Study showed that higher levels of a mother’s blood sugar during pregnancy are associated with higher risks of increased birthweight, fatter babies, delivery by Cesarean Section, low blood sugar in newborn babies and high levels of insulin in the cord blood at birth. It is not clear whether levels of a mother’s blood sugar during pregnancy are associated with risk obesity later in life as is known to occur in offspring or pre-existing maternal diabetes mellitus. With funding from the National Institutes of Health, the HAPO Follow Up Study addressed this in a subset of nearly 5,000 mothers and their children from the original HAPO Study 10-14 years later (average 11.4 years).

Author Interviews, JAMA, OBGYNE, STD, USPSTF / 09.09.2018

MedicalResearch.com Interview with: Melissa A. Simon, M.D., M.P.H. Member, U.S. Preventive Services Task Force George H. Gardner professor of clinical gynecology, Vice chair of clinical research Department of Obstetrics and Gynecology Professor of preventive medicine and medical social sciences Northwestern University Feinberg School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: The number of babies born with syphilis is increasing, mirroring the recent increase of syphilis among women. Syphilis infection passed from a pregnant woman to her baby, also known as congenital syphilis, can lead to serious health complications for the baby including premature birth, low birthweight, birth defects, and even death. The Task Force recommends that all pregnant women be screened for syphilis as early in pregnancy as possible to prevent congenital syphilis.  (more…)

MedicalResearch.com Interview with: Michelle H. Moniz, MD, MSc Assistant Professor Department of Obstetrics and Gynecology Ann Arbor, MI 48109-2800 MedicalResearch.com: What is the background for this study? What are the main findings? Response: We wanted to examine whether Medicaid expansion in Michigan was associated with improved access to birth control/family planning services in our state.  We conducted a survey of enrollees in the Michigan Medicaid expansion program (called "Healthy Michigan Plan"). We found that 1 in 3 women of reproductive age reported improved access to birth control/family planning services after joining HMP.  Women who were younger, who were uninsured prior to joining HMP, and those who had recently seen a primary care clinician were most likely to report improved access.  (more…)
Author Interviews, Endocrinology, Kaiser Permanente, Menopause, OBGYNE, Pediatrics, Pediatrics, Vaccine Studies / 30.08.2018

MedicalResearch.com Interview with: Allison L. Naleway, PhD Senior Investigator Associate Director, Science Programs Center for Health Research Kaiser Permanente MedicalResearch.com: What is the background for this study? Response: Reports of premature menopause after human papillomavirus (HPV) vaccination have received a lot of media attention, including on social media, but these reports were based on a small number of isolated cases. Large studies have demonstrated the safety of HPV vaccination, but parental safety concerns—including potential impact on future fertility—are often cited as one reason for lower HPV coverage. Rates of HPV vaccination have lagged behind coverage rates for other recommended adolescent vaccinations, such as tetanus-diphtheria-acellular pertussis and meningococcal conjugate. (Based on national coverage estimates from 2016, 65% of 13–17 year-old females received at least one HPV vaccination and only 49.5% were up to date with the series, compared to about 88% of adolescents who received Tdap.) We conducted a study of nearly 200,000 young women to determine whether there was any elevated risk of primary ovarian insufficiency (POI) after HPV or other recommended vaccinations.  (more…)
Author Interviews, Cancer Research, JAMA, OBGYNE, UCLA / 29.08.2018

MedicalResearch.com Interview with: Dr. Carol Mangione, M.D., M.S.P.H., F.A.C.P. Division Chief of General Internal Medicine and Health Services Research Professor of Medicine Barbara A. Levey, MD, and Gerald S. Levey, MD, endowed chair in Medicine David Geffen School of Medicine University of California, Los Angeles (UCLA) professor of public health at the UCLA Fielding School of Public Health. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Screening for cervical cancer saves lives by identifying cervical cancer early when it is treatable. Most cases of cervical cancer occur in women who have not been regularly screened or treated, which is why it’s important for women to get screened regularly throughout their lifetime with one of several effective options. Women ages 21 to 29 should get a Pap test every three years. Women ages 30-65 can choose between three approaches, depending on their preferences: a Pap test every three years, an HPV test every five years, or a combination of a Pap test and an HPV test every five years. There are some women who don’t need to be screened for cervical cancer including women younger than 21, women older than 65 who have been adequately screened in the past and are not at high risk, and women who have had a hysterectomy.  (more…)
Author Interviews, JAMA, NEJM, OBGYNE, University Texas / 09.08.2018

MedicalResearch.com Interview with: George R. Saade, MD Professor Jennie Sealy Smith Distinguished Chair Professor, Obstetrics & Gynecology, and Cell Biology Chief of Obstetrics and Maternal Fetal Medicine Director, Perinatal Research Division Department of Obstetrics and Gynecology Division of Maternal Fetal Medicine UTMB at Galveston MedicalResearch.com: What is the background for this study? Response: Several analyses show that the lowest risk to the baby is if delivered at 39 weeks. As pregnancy goes beyond 39 weeks, the risk to the baby increases. On the other hand, the general belief was that induction of labor at 39 increases the risk of cesarean and may not be good for the baby. The guideline were that induction without medical indication, or what we call elective induction of labor, should not be done. However, the studies on which this belief was based were not appropriately designed or analyzed. These studies compared women who were induced at 39 weeks to those who had spontaneous labor at 39 weeks. This comparison is not appropriate. While induction is a choice, having spontaneous labor at 39 weeks is not by choice.  So the correct comparison should be between women who were induced at 39 weeks to those who were not induced and continued their pregnancy beyond 39 weeks. In other words, they continued until they had spontaneous labor or developed an indication to be delivered (expectantly managed). That is how the study was done. First time pregnant women were randomized between these 2 options. The reason the study was done in first time mothers is that they have the highest risk of cesarean compared with women who had delivered vaginally before. (more…)
Abbvie, Author Interviews, OBGYNE, Pain Research / 26.07.2018

MedicalResearch.com Interview with: Dr. Dawn Carlson MD MPH Vice President, General Medicine Development AbbVie  MedicalResearch.com: Please provide some background on this announcement. Would you briefly explain what endometriosis is? Whom does it affect and how does it interfere with quality of life? Response: Endometriosis is one of the most common gynecologic disorders in the U.S that affects an estimated one in 10 women of reproductive age. It occurs when tissue similar to the lining of the uterus starts growing outside of the uterus, where it doesn’t belong. The symptoms of endometriosis, including pain with menstrual periods and between periods, and with sexual intercourse, can be debilitating and significantly impact day-to-day activities of women’s lives, personally and professionally. Unfortunately, women with endometriosis can suffer for up to 10 years and visit multiple physicians before receiving a proper diagnosis. Unresolved endometriosis pain results in higher healthcare costs from emergency department visits and repeat surgeries.  (more…)
Author Interviews, HIV, OBGYNE, Pediatrics, Pediatrics, STD / 24.07.2018

MedicalResearch.com Interview with: Monika K. Goyal, M.D., M.S.C.E., senior study author Assistant professor of Pediatrics and Emergency Medicine Children’s National Health System Washington, DC  MedicalResearch.com: What is the background for this study? Response: Patients with pelvic inflammatory disease (PID) are at an increased risk for syphilis and HIV. We know that adolescents account for 20 percent of the 1 million cases of PID that are diagnosed each year. We also know that an estimated one in four sexually active adolescent females has a sexually transmitted infection (STI). While screening for syphilis and HIV is recommended when diagnosing PID, actual screening rates among adolescents have been understudied. This multi-center study aimed to quantify rates of HIV and syphilis screening in young women diagnosed with . pelvic inflammatory disease in pediatric emergency departments and to explore patient- and hospital-specific characteristics associated with screening for these two sexually transmitted infections.

Author Interviews, Depression, JAMA, OBGYNE / 15.07.2018

MedicalResearch.com Interview with: Rebecca Pearson, PhD Lecturer in Psychiatric Epidemiology Centre for Academic Mental Health School of Social & Community Medicine University of Bristol MedicalResearch.com: What is the background for this study? What are the main findings?  Response: We know depression and anxiety are common in young women and during pregnancy when there are also implications for the developing child. It is therefore important to investigate whether symptoms are rising given the pressures of modern life. We found that compared to their mothers generation in the 1990s young pregnancy women today are more likely to be depressed. This was driven largely by symptoms of anxiety and feeling overwhelmed rather than feeling down.  (more…)

MedicalResearch.com Interview with: Dr Elizabeth R Cluett  PhD MSc RM RGN PGCEA PFHEA Senior Lecturer, Faculty of Health Sciences University of Southampton Southampton UK MedicalResearch.com:What is the background for this study? Response: Water immersion during labor and birth is increasingly popular and is becoming widely accepted across many countries, and particularly in midwifery-led care settings. Immersion in water during labor and birth facilitates physiological labor and birth, offers women a non-pharmacological pain relief option and facilitates a sense of choice, control and comfort; qualities strongly associated with women’s satisfaction with their birth experience.

Author Interviews, JAMA, Mental Health Research, Nutrition, OBGYNE / 05.07.2018

MedicalResearch.com Interview with: Joshua L. Roffman, MD Department of Psychiatry Mass General Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: Autism, schizophrenia, and other serious mental illness affecting young people are chronic, debilitating, and incurable at present.  Recent public health studies have associated prenatal exposure to folic acid, a B-vitamin, with reduced subsequent risk of these illnesses.  However, until this point, biological evidence supporting a causal relationship between prenatal folic acid exposure and reduced psychiatric risk has remained elusive. We leveraged the rollout of government-mandated folic acid fortification of grain products in the U.S. from 1996-98 as a "natural experiment" to determine whether increased prenatal folic acid exposure influenced subsequent brain development.  This intervention, implemented to reduce risk of spina bifida and other disabling neural tube defects in infants, rapidly doubled blood folate levels among women of childbearing age in surveillance studies. Across two large, independent cohorts of youths age 8 to 18 who received MRI scans, we observed increased cortical thickness, and a delay in age-related cortical thinning, in brain regions associated with schizophrenia risk among individuals who were born during or after the fortification rollout, compared to those born just before it.  Further, delayed cortical thinning also predicted reduced risk of psychosis spectrum symptoms, a finding that suggests biological plausibility in light of previous work demonstrating early and accelerated cortical thinning among school-aged individuals with autism or psychosis.

Author Interviews, Cancer Research, JAMA, OBGYNE / 04.07.2018

MedicalResearch.com Interview with: Dr. Gina Ogilvie | MD MSc FCFP DrPH Professor | Faculty of Medicine | University of British Columbia Canada Research Chair | Global control of HPV related disease and cancer Senior Public Health Scientist | BC Centre for Disease Control Senior Research Advisor | BC Women's Hospital and Health Centre BC Women's Hospital and Health Centre Vancouver, BC MedicalResearch.com: What is the background for this study? What are the main findings? Response: HPV is known to be the cause of 99% of cervcial cancers. In this study, we compared the routine screening test for cervical cancer, Pap test, to HPV testing. We found that by using HPV testing, women were significantly more likely to have cervical pre-cancers detected earlier. In addition, women with negative HPV tests were significantly less likely to have pre-cancers 48 months later. (more…)
Annals Internal Medicine, Author Interviews, Blood Pressure - Hypertension, Brigham & Women's - Harvard, Heart Disease, OBGYNE / 03.07.2018

MedicalResearch.com Interview with: Jennifer J. Stuart, ScD Postdoctoral Research Fellow in Reproductive & Cardiovascular Epidemiology Department of Epidemiology Harvard T.H. Chan School of Public Health Division of Women's Health Brigham and Women's Hospital and Harvard Medical School  MedicalResearch.com: What is the background for this study? Response: Preeclampsia and gestational hypertension are common pregnancy complications involving high blood pressure that develops for the first time during pregnancy and returns to normal after delivery. Approximately 10 to 15% of all women who have given birth have a history of either preeclampsia or gestational hypertension. Previous studies have shown that women with a history of high blood pressure in pregnancy are more likely to develop cardiovascular disease events like heart attack and stroke later in life when compared to women with normal blood pressure in pregnancy. However, what is less clear is to what extent these women are more likely to develop chronic hypertension, diabetes, and high cholesterol and when these risk factors begin to emerge after pregnancy. We examined this question in a cohort of nearly 60,000 American women who we were able to follow for up to 50 years after their first pregnancy. Previous studies have been limited by small numbers, short follow-up, or a lack of information on shared risk factors, such as pre-pregnancy body mass index, smoking, and family history. This research was conducted within the Nurses’ Health Study II, which collected data on these pre-pregnancy factors in tens of thousands of women over several decades. (more…)
Author Interviews, JAMA, OBGYNE, Surgical Research / 29.06.2018

MedicalResearch.com Interview with: Sarah CM Roberts, DrPH Associate Professor ObGyn&RS Zuckerberg San Francisco General UCSF MedicalResearch.com: What is the background for this study? What are the main findings? Response: Thirteen states have laws that require abortions to be provided in Ambulatory Surgery Centers (ASCs); many of these laws apply only in the second trimester.  We examined outcomes from more than 50,000 abortions provided in two facility types:  Ambulatory Surgery Centers and office-based settings. We found that there was no significant difference in abortion-related complications across facility type; in both settings, about 3.3% had any complication and about 0.3% had a major complication.  There also was no significant difference in complications across facility types for second trimester and later abortions.

Author Interviews, OBGYNE, Pediatrics / 23.06.2018

MedicalResearch.com Interview with: Melissa Lorenzo MD Pediatric medical resident Dr. Lorenzo is currently training at the University of Toronto, however the research was conducted while a medical student at Queens University MedicalResearch.com: What is the background for this study? Response: Preterm infants are born before 37 weeks gestation, with late preterm neonates defined as infants born between 34 weeks to 37 weeks gestation. Of all preterm births, over 70% of babies are born in the late preterm period. Late preterm births are common, affecting 12.5% of all births in the United States. Compared to infants born at term, late preterm neonates are at increased risk for many common complications following birth such as jaundice, low blood sugar, and respiratory distress, prolong hospital stay, admission to the neonatal intensive care unit, and increase readmission rate after hospital discharge. There are many causes for preterm delivery- two important ones are early onset of labour either spontaneous or after premature rupture of membranes, and medically indicated delivery prior to full term gestation due to chronic diseases in mother affecting her health in pregnancy, fetal medical reasons, or placental insufficiency. There is a debate that the risk of neonatal complications is affected by the causes of preterm delivery with immaturity acting as a contributing factor. The relative contribution of immaturity versus the reason for delivery and the resulting neonatal complications is unclear. (more…)

MedicalResearch.com Interview with: “Birth” by Sharon Mollerus is licensed under CC BY 2.0Giulia Muraca, PhD, MPH Postdoctoral Fellow School of Population and Public Health BC Children’s Hospital Research Institute Faculty of Medicine University of British Columbia MedicalResearch.com: What is the background for this study? What are the main findings?  Response: While cesarean delivery rates have increased in Canada over the last few decades, as in most industrialized settings, the rate of forceps and vacuum deliveries have declined. These opposing trends have led to recommendations to increase forceps and vacuum delivery rates as a strategy to reduce cesarean delivery rates. We found that the rate of obstetric trauma in Canada increased significantly in recent years, especially among forceps deliveries. In first-time mothers, the rate of obstetric trauma increased by 7% among forceps deliveries (from 19.4% in 2004 to 26.5% in 2014) and in women who had a previous cesarean delivery, the rate of obstetric trauma among forceps deliveries increased by 9% (from 16.6% to 25.6%). We found that a 1% increase in the forceps and vacuum delivery rate in Canada was associated with approximately 700 additional cases of obstetric trauma and 18 additional cases of severe birth trauma annually among first-time mothers alone.  (more…)
Author Interviews, Infections, OBGYNE, Pediatrics, Vaccine Studies / 17.06.2018

MedicalResearch.com Interview with: Sylvia Becker-Dreps, MD MPH Associate Professor, Department of Family Medicine Associate Director, Office of International Activities (Latin America Focus) Director, UNC Program in Nicaragua University of North Carolina at Chapel Hill Chapel Hill, NC 27599-7595 MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Pertussis (or whooping cough) is a respiratory infection caused by bacteria. It has been becoming more common in the US over the past two decades. Infants are more likely to be hospitalized and die of the disease. They are especially vulnerable in the first months of life because they have not yet had time to complete the DTaP vaccine series themselves. (Currently, infants receive 3 doses of DTaP at 2,4, and 6 months of age.) Immunizing mothers allows the mothers to pass antibodies against pertussis through the placenta and provide passive immunity to infants early in life. In early 2013, the CDC recommended that pregnant women receive a Tdap vaccine in every pregnancy. That recommendation was based on studies of the immune response to the vaccine, not real cases of pertussis. Our study examined clinical cases of pertussis in over 675,000 infants throughout the US. We found that in the first six months of life, infants of vaccinated mothers (those that received Tdap during pregnancy) had 75% less pertussis hospitalizations and 50% less pertussis cases overall.  (more…)
Author Interviews, JAMA, OBGYNE / 12.06.2018

MedicalResearch.com Interview with: Björn Pasternak, MD, PhD Associate Professor,Clinical Epidemiology Division Department of Medicine Solna Karolinska Institutet Stockholm, Sweden MedicalResearch.com: What is the background for this study? Response: To summarize the background for this study, there have been animal studies suggesting that oral fluconazole may give rise to fetal death. Given this background and the paucity of controlled human studies, we previously conducted a nationwide register-based study in Denmark, which was published in JAMA in 2016. In that study, we observed an increased risk of spontaneous abortion associated with fluconazole use in pregnancy. This prompted the European Medicines Agency to update the European label of fluconazole, warning about this potential adverse event. Further, findings in that study indicated that there could be an increased risk of stillbirth. We wanted to investigate this outcome further, in an independent data material, and also to investigate the outcome of neonatal death. Here, we report the results of a bi-national study conducted on the basis of nationwide health care registers in Sweden and Norway. From a background cohort of close to 1.5 million deliveries, we identified more than 10,000 pregnancies exposed to oral fluconazole and matched these to more than 100,000 unexposed pregnancies.

MedicalResearch.com Interview with: Sheryl L. Rifas-Shiman, MPH Lead Research Analyst Department of Population Medicine Harvard Medical School and Harvard Pilgrim Health Care Institute Landmark Center Boston, MA 02215  MedicalResearch.com: What is the background for this study? Response: Caesarean delivery rates remain high and variable across hospitals, regions, and countries. Caesarean delivery may be a risk factor for childhood obesity, possibly because delivery route can influence the intestinal microbiomes, which may influence energy regulation. Previously reported associations of caesarean delivery with childhood obesity may be confounded by maternal BMI and sociocultural factors. To address this possibility, we studied sibling pairs from the Linked CENTURY Study, a longitudinal clinical database of well-child visits in Massachusetts linked to each child’s birth certificate, to isolate the effect of caesarean delivery from most other factors.

MedicalResearch.com Interview with: Manish Sagar, MD Infectious Disease Physician at Boston Medical Center Boston MA  MedicalResearch.com: What is the background for this study? Response: Women compromise the majority of new infections in the world and most of them acquire the virus after sexual exposure.  The goal of the study was to understand how HIV establishes initial infection in the female genital tract. We obtained discarded vaginal tissue and isolated cells present in the outermost layer that contact the virus during exposure. (more…)

Davidge, PhD, FCAHS Executive Director, Women and Children's Health Research Institute Canada Research Chair in Maternal and Perinatal Cardiovascular Health Professor, Depts. of Ob/Gyn and Physiology University of Alberta Edmonton, Alberta Canada MedicalResearch.com: What is the background for this study? Response: This research contributes to the growing body of literature that developmental programming of adult onset cardiovascular disease originates in the womb. Our study is among the first to discover that maternal age may be considered a ‘prenatal stress’ in certain circumstances. (more…)
Author Interviews, Autism, Blood Pressure - Hypertension, JAMA, OBGYNE, Pediatrics / 08.06.2018

MedicalResearch.com Interview with: “Blood Pressure” by Bernard Goldbach is licensed under CC BY 2.0Ali Khashan, PhD Senior Lecturer in Epidemiology School of Public Health & INFANT Centre University College Cork Cork, Ireland MedicalResearch.com: What is the background for this study? What are the main findings? Response: There is some evidence to suggest an increased likelihood of neurodevelopmental disorders in relation to hypertensive disorders in pregnancy, however consensus is lacking. Considering hypertensive disorders in pregnancy are among the most common prenatal complication, we decided to synthesise the published literature on this topic by conducting a comprehensive systematic review and meta-analysis. Our main findings suggest that hypertensive disorders in pregnancy are associated with about 30% increase in the likelihood of autism spectrum disorders (ASD) and ADHD in the offspring, compared to offspring not exposed to hypertensive disorders in pregnancy.

Author Interviews, Columbia, OBGYNE, Toxin Research / 29.05.2018

MedicalResearch.com Interview with: Marianthi-Anna Kioumourtzoglou ScD Assistant Professor Environmental Health Sciences Mailman School of Public Health Columbia University  MedicalResearch.com: What is the background for this study? Response: The prevalence of neurodevelopmental disorders, like attention deficit/hyperactivity disorder (ADHD) has been increasing. One of the hypothesized risk factors for increased risk for neurodevelopmental disorders is a class of chemicals known as endocrine disrupting chemicals (EDCs). These chemicals are known to interfere with the endocrine system, i.e. the system that uses hormones to control and coordinate metabolism, reproduction and development. Several high production volume chemicals, ubiquitously present in commercial products, are known or suspected endocrine disruptors. Because of their widespread use in consumer products, the population-wide exposure to known and suspected EDCs is very high. Recently, there has been increased attention in the potential effects of EDCs on neurodevelopment that span multiple generations. Animal studies have provided evidence that exposure to EDCs, such as phthalates and bisphenol A (BPA), alter the behavior and social interactions in mice in three to five generations after exposure. However, evidence of such multi-generational impacts of EDC exposure on neurodevelopment in humans is unavailable, likely because of the lack of detailed information on exposures and outcomes across generations. For this study we leveraged information from a nationwide cohort, the Nurses’ Health Study II (NHSII), to investigate the potential link between exposure to diethylstilbestrol (DES) and third generation ADHD, i.e. ADHD among the grandchildren of the women who used DES while pregnant. DES is a very potent endocrine disruptor that was prescribed between 1938 and 1971 to pregnant women thought to prevent pregnancy complications. In the United States, between 5 and 10 million women are estimated to have used DES, although the exact number is not known. DES was banned in 1971, when was linked to vaginal adenocarcinomas (a rare cancer of the reproductive system) in the daughters of the women who had used it during pregnancy. Since then, DES has been also linked to multiple other reproductive outcomes in DES daughters, as well as with some reproductive outcomes in the grandchildren of the women who used it, such as hypospadias and delated menstrual regularization. However, to our knowledge, no study to date has evaluated the association between DES, or any other EDC, and multigenerational neurodevelopment. (more…)
Author Interviews, Autism, Environmental Risks, Fish, OBGYNE, Toxin Research / 23.05.2018

MedicalResearch.com Interview with: “Fish” by Dhruvaraj S is licensed under CC BY 2.0Dr Caroline M Taylor Wellcome Trust Research Fellow Centre for Child and Adolescent Health Bristol Medical School, University of Bristol Oakfield House, Oakfield Grove, Bristol MedicalResearch.com: What is the background for this study? Response: Mercury is a toxic metal that is widespread in the environment. In pregnancy, mercury in the mother’ bloodstream is transferred through the placenta to the fetus, where is can affect development of the nervous system. Mercury from vaccines has been the focus of attention particularly in regard to a link with autism in children. However, the amount of mercury used in the vaccines is small in comparison with mercury from the diet and atmospheric pollution, and in the EU at least, childhood vaccines no longer contain this preservative. The fear that mercury is linked to autism has persisted, despite increasing evidence that this is not the case. The aim of our study was to look at mercury from the diet rather than vaccines – specifically from fish – in pregnant women. We measured the women’s mercury levels in their blood and asked them about how much fish they ate. We then followed up their children for 9 years and recorded how many of them had autism diagnosed within that time. We also measured how many of them had autist traits by measuring their social and communication difficulties.  The data were part of the Children of the 90s study (Avon Longitudinal Study of Parents and Children – ALSPAC), which is based in Bristol, UK.

MedicalResearch.com Interview with: “Acupuncture Needle” by Acid Pix is licensed under CC BY 2.0Caroline Smith, PhD Professor Clinical Research Western Sydney University Research Theme Champion Health and Wellbeing MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Despite technological improvements to IVF the success of IVF treatment remains low. Consequently, new drugs, laboratory techniques and other treatments need to be developed and rigorously tested to explore their effects on producing healthy babies for women undergoing IVF.  In 2002, the first randomised controlled trial of acupuncture administered a specific form of IVF acupuncture at the time of embryo transfer. The results indicated the chance of achieving a pregnancy from acupuncture was twice that to women undergoing IVF treatment alone. From mid 2000s many women have started to use adjunctive treatments such as acupuncture whilst undergoing IVF.  We conducted and reported on a  pilot study in 2006 which produced results suggesting a benefit. It is important that these findings were rigorously examined in a larger trial. Findings are presented from our trial presented in JAMA. Our study of over 800 Australian and New Zealand women undergoing acupuncture treatment during their IVF (in vitro fertilization) cycle has failed to confirm significant difference in live birth rates.

MedicalResearch.com Interview with: Dr. Cande V. Ananth, PhD, MPH Adjunct professor Department of Health Policy and Management Mailman School of Public Health Columbia University, NY MedicalResearch.com: What is the background for this study? Response: Preterm delivery rates have declined between 2005 and 2014 in the US and in several European countries. Since reductions in preterm and early term deliveries, and perinatal mortality remain a global health priority, determining the relationship between gestational age distribution and perinatal mortality, remains a challenge. Efforts expended to a more complete understanding of the impact of new interventions, policies, and practices on reducing the burden of early deliveries, and in turn improvements in perinatal survival will be of tremendous benefit for clinical management and care of women during their pregnancy and the newborn.

Author Interviews, CMAJ, OBGYNE / 07.05.2018

MedicalResearch.com Interview with: “Childbirth” by DAVID Swift is licensed under CC BY 2.0 Dr. Carmen Young Department of Obstetrics and Gynecology University of Alberta MedicalResearch.com: What is the background for this study? Response: For women who have had a single previous cesarean section, the optimal mode of delivery in a subsequent pregnancy is controversial. This is because there are risks and benefits to attempting a vaginal birth after cesarean section (VBAC) or having an elective repeat cesarean section. Attempted VBAC is associated with a higher risk of uterine rupture and other maternal and infant complications. Repeat cesarean sections are associated with an increased risk of surgical complications and placental complications in subsequent pregnancies. Furthermore, it is difficult to predict which patients will have a successful VBAC. This study is unique in that it uses recent Canadian data, allowing assessment of the impact of contemporary obstetrical care on maternal and neonatal outcomes in Canada. (more…)

MedicalResearch.com Interview with: “Soda” by Jannes Pockele is licensed under CC BY 2.0Juliana F. W. Cohen, ScM, ScD Department of Health Sciences Merrimack College North Andover MA 01845. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Sugar consumption among Americans is above recommended limits and this excess intake may have important health implications. This study examined the associations of pregnancy and offspring sugar consumption, as well as sugar-sweetened beverages, other beverages (diet soda, juice), and fruit consumption with child cognition. This study found that when pregnant women or their children consumed greater quantities of sugar, as well as when women consumed diet soda during pregnancy, this was associated with poorer childhood cognition.  However, children’s fruit consumption was associated with higher cognitive scores.
