MedicalResearch.com: What is the background for this study?
Response: For several decades now, subclinical thyroid disease, variously defined, has been associated with adverse pregnancy outcomes. In 1999, two studies are responsible for increasing interest in subclinical thyroid disease during pregnancy because it was associated with impaired neuropsychological development in the fetus. One study showed that children born to women with the highest TSH levels had lower IQ levels. The other showed that children of women with isolated low free thyroid hormone levels performed worse on early psychomotor developmental tests. Together, these findings led several experts and professional organizations to recommend routine screening for and treatment of subclinical thyroid disease during pregnancy.
Our study was designed to determine whether screening for either of these two diagnoses and treatment with thyroid hormone replacement during pregnancy actually improved IQ in children at 5 years of age.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Pregnant women are at increased risks of severe disease and death due to influensa infection, as well as hospitalization. Also influenza and fever increase the risk of adverse pregnancy outcomes for their infants such as intrauterine death and preterm birth. Due to this, the regulatory agencies in Europe and the US recommended post exposure prophylaxis and treatment for pregnant women with neuraminidase inhibitors during the last influenza pandemic 2009-10. Despite the recommendations, the knowledge on the effect of neuraminidase inhibitors on the infant has been limited. Previously published studies have not shown any increased risk, but they have had limited power to assess specific neonatal outcomes such as stillbirth, neonatal mortality, preterm birth, low Agar score, neonatal morbidity and congenital malformations.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The World Health Organization recommends that infants should be breastfed exclusively until six months of age with breastfeeding continuing as an important part of the infant’s diet until he or she is at least two years old. Breastfeeding has an important impact on the short-term and long-term health of both infants and their mothers. There is good evidence that not breastfeeding increases mortality and morbidity due to infectious diseases. Not breastfeeding is also associated with increases in hospitalisation for problems such as gastroenteritis, respiratory disease, and ear infections, as well as higher rates of childhood diabetes, obesity and dental disease.
Breastfeeding is also important for women’s health. It’s been found that not breastfeeding is associated with increased risks of breast and ovarian cancer, and diabetes. Few health behaviours have such a broad-spectrum and long-lasting impact on population health, with the potential to improve life chances, health and well-being. It has been estimated that each year, 823,000 deaths in children under five years and 20,000 deaths from breast cancer could be prevented by near universal breastfeeding.
However, many women stop breastfeeding before they want to as a result of the problems they encounter. Current breastfeeding rates in many countries do not reflect the WHO recommendation. Only around 37% of babies under six months worldwide are exclusively breastfed, and in many high and middle income countries, the rates are much lower. Good care and support may help women solve these problems so that they can continue to breastfeed.

MedicalResearch.com: What is the background for this study?
Response: Physical activity improves health and may delay the onset of chronic diseases. For women in particular, the rate of some chronic diseases accelerates at middle age around the time of menopause; therefore it is important to identify the determinants of health-enhancing physical activity during midlife in this population.
The main aim of this study was to characterize the level of physical activity and to examine the association between different female reproductive factors and objectively-measured physical activity in middle-aged women. The reproductive factors included cumulative reproductive history index, and perceived menopausal and pelvic floor dysfunction symptoms.

MedicalResearch.com: What is the background for this study?
Response: Infant-directed (ID) singing allows infants to have emotionally-synchronized interactions with caregivers, during which they gain valuable experience in self-regulation. Maternal depression can disrupt mother-infant interaction, thus hindering infants’ efforts at self-regulation and possibly contributing to a depressed interaction style that can generalize to infant interaction with strangers. Additionally, maternal depression can alter the acoustic parameters of ID singing, such that mothers may not modify musical elements (i.e., tempo and key), to accommodate infant state.
18 Feb Air Pollution Linked To Millions of Preterm Births

MedicalResearch.com: What is the background for this study?
Response: When a baby is born preterm (at less than 37 weeks of gestation, an indicator of premature birth), there is an increased risk of infant death, or long-term physical and neurological disabilities. For example, 965,000 infant deaths in 2013 (35% of all neonatal deaths) have been estimated to be due to preterm birth complications. In 2010, an estimated 14.9 million births were preterm – about 4–5% of the total in some European countries, but up to 15–18% in some African and South Asian countries. The human and economic costs are enormous.
There are many risk factors for preterm birth – from the mother’s age, to illness, to poverty and other social factors. Recent research has suggested that exposure to air pollution could also be a risk factor. Our study quantifies for the first time the global impact of pregnant women's exposure to outdoor fine particulate matter (PM2.5) by combining data about air pollution in different countries with knowledge about how exposure to different levels of air pollution is associated with preterm birth rates.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The proportion of women who are overweight or obese is increasing in almost all countries worldwide, and this is being accompanied by an increased risk of developing both type 2 diabetes (T2D) (whether pregnant or not) and gestational diabetes (GDM). While other studies have analysed the links between GDM and adverse outcomes in babies, very large studies that draw on an entire national database, study, are rare.
In our research, all 796,346 deliveries taking place after 22 weeks in France in 2012 were included by extracting data from the hospital discharge database and the national health insurance system. Outcomes were analysed according to the type of diabetes and, in the GDM group, whether or not diabetes was insulin-treated.
The cohort of 796,346 deliveries involved 57,629 (7.24%) mothers with gestational diabetes mellitus. Data linking the mother to the child were available for 705,198 deliveries (88% of the total). The risks of adverse outcomes were two to four times higher for babies of mothers with type 2 diabetes before pregnancy (pregestational diabetes) than for those with GDM. We then adjusted our data, limiting the analysis to deliveries after 28 weeks to ensure all women diagnosed with GDM were included (since diagnosis of GDM in most cases takes place at or after 28 weeks).
Following adjustment, the increased risk of various complications for mothers with gestational diabetes versus mothers without GDM were: preterm birth 30%; Caesarean section 40%; pre-eclampsia/eclampsia 70%; babies born significantly larger than average size (macrosomia) 80%; respiratory distress 10%; birth trauma 30%; and cardiac malformations 30%. While these increased risks combine women with both insulin- and diet-treated GDM, most of the increased risk is found in women with insulin-treated GDM. This is because as stated above, the diabetes is more serious and blood sugar more difficult to control in women who need insulin treatment, resulting in a higher risk of complications than in those women treated with diet only.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Several medical advances have been made over the past two decades to improve the care and survival of infants born pre-term. However, approaches to care differ greatly among providers for infants born at the limits of viability (22 to 24 weeks gestation), far earlier than the 40 weeks generally expected for a pregnancy to reach full-term. Little is known about the outcomes of these infants, particularly whether those who survive experience significant neurodevelopmental impairments.
RTI served as the data coordinating center for this research that examined the survival and neurodevelopmental impairment at 18-22 months corrected age of over 4,000 infants born at 22 to 24 weeks gestation during 2000 to 2011 at medical centers participating in a national research network funded by the NIH. In this group of babies, infant survival improved over time from survival rates of 30 percent in 2000-2003 to 36 percent in 2008-2011. The proportion of infants who survived without a neurodevelopmental impairment also increased from 16 percent in 2000-2003 to 20 percent in 2008-2011.
17 Feb Paternal Depression Linked To Not Being in Relationship With Mother
MedicalResearch.com Interview with: Lisa Underwood, PhD Research Fellow| Centre for Longitudinal Research Growing Up in New Zealand | Who are Today’s Dads? School of Population Health, Faculty of Medical & Health Sciences University of Auckland Auckland MedicalResearch.com: What is the background for this study? What are the main findings? Response: This study is part of the contemporary, longitudinal study Growing Up in New Zealand, which is tracking the development of more than 6000 children born in 2009 and 2010. In previous reports we investigated antenatal and postnatal depression symptoms among the mothers of our cohort children. In this study we looked at the partners of those mothers to explore whether men and women have different risks for depression in each perinatal period. Our main findings were that expectant fathers were at risk if they felt stressed or were in poor health. Elevated depression symptoms following their child’s birth, were also linked to social and relationship problems. The strongest predictor of postnatal paternal depression was no longer being in a relationship with the child’s mother.11 Feb Almost 40% of Assisted Reproductive Infants Are Multiple Births
MedicalResearch.com Interview with: Saswati Sunderam, 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: Assisted Reproductive Technology Surveillance – United States, 2014, the surveillance summary published this week in CDC’s Morbidity and Mortality Weekly Report (MMWR), presents state-specific data on assisted reproductive technology (ART) use and outcomes. The report compares ART infant outcome data with outcomes for all infants born in the U.S. in 2014, and provides data on the contributions of Assisted Reproductive Technology to total infants born, multiple birth infants, low birth weight infants, and preterm infants for each U.S. state, the District of Columbia, and Puerto Rico.01 Feb Oxytocin During Labor Linked to Increased Risk of Postpartum Depression

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Because of effects on social behavior, including maternal behavior, oxytocin has often been seen as a potential mediator of postpartum depression and anxiety.
The original objective of our study was to examine the relationship between the use of synthetic oxytocin during and after labor and the development of depressive and anxiety disorders within the first year postpartum. We hypothesized that women exposed to synthetic oxytocin before or during labor would have a reduced risk of postpartum depressive and anxiety disorders compared with those without any exposure. Our findings told the opposite story.
We found that peripartum synthetic oxytocin exposure was associated with an increase in risk for the development of postpartum depression and anxiety.
30 Jan Does IVF Raise Risk of Malignancies in Offspring?
MedicalResearch.com Interview with: Tamar Wainstock, PhD Department of Public Health; Faculty of Health Sciences Ben-Gurion University of the Negev ISRAEL MedicalResearch.com: What is the background for this study? Response: There is a controversy in the medical literature regarding the possible association between infertility or infertility treatments, and the long-term offspring neoplasm risk: while some studies have found such an association, others have not. Since the number of offspring conceived following treatments are growing, and as they age, it is critical to clarify this possible association.27 Jan Thyroid Hormone Treatment In Pregnant Women With Subclinical Hypothyroidism

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Subclinical hypothyroidism, a mild thyroid dysfunction, has been associated in pregnancy with multiple adverse outcomes. Our aim was to estimate the effectiveness and safety of thyroid hormone treatment among pregnant women with subclinical hypothyroidism.
Using a large national US dataset, we identified 5,405 pregnant women diagnosed with subclinical hypothyroidism. Of these, 843 women, with an average pretreatment TSH concentration of 4.8 milli-international units per liter, were treated with thyroid hormone. The remaining 4,562, with an average pretreatment TSH concentration of 3.3 milli-international units per liter, were not treated.
Compared with the untreated group, treated women were 38 percent less likely to experience pregnancy loss. However, they were more likely to experience a preterm delivery, gestational diabetes or preeclampsia. Moreover, the benefit of thyroid hormone treatment on pregnancy loss was seen only among women with higher TSH levels (4.1 to 10 mIU/L) before treatment. We also found that for women with lower levels of TSH (2.5–4.0 mIU/L), the risk of gestational hypertension was significantly higher for treated women than for untreated women.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: We have been involved in earlier work which applied the same methods used here (using genetic variants to provide causal evidence) and showed that higher maternal pregnancy body mass index (BMI) causes greater infant birth weight. The paper here aimed to build on that earlier research and asked whether maternal BMI in pregnancy has a lasting effect, so that offspring of women who were more overweight in pregnancy are themselves likely to be fatter in childhood and adolescence. Our aim was to address this because an effect of an exposure in pregnancy on later life outcomes in the offspring could have detrimental health consequences for themselves and future generations. However, we did not find strong evidence for this in the context of the impact of maternal BMI in pregnancy on offspring fatness.

MedicalResearch.com: What is the background for this study?
Response: Based on data from the Centers for Disease Control and Prevention, the United States maternal mortality ratio is three to four times higher than that of most other developed nations. Previous studies from the demonstrated a possible association between weekend hospital admissions and higher rates of mortality and poor health outcomes.
We investigated differences in maternal and fetal death ratios on weekends compared to weekdays and during different months of the year. In addition we investigated the presence of any medical and obstetrics complications in women who gave birth to a live child and in their offspring by day of delivery.
25 Jan Does Limiting Weight Gain in Pregnancy Reduce Complications?

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Excess maternal weight gain during pregnancy is very common in the United States, and has been associated with a number of pregnancy complications, including gestational diabetes, maternal hypertension, excess fetal size, and cesarean delivery.
Children born to mothers who gained excessively during pregnancy are at much higher risk of developing obesity themselves. We performed a randomized trial where half of the women received an intensive intervention of diet and exercise counseling in an effort to limit their weight gain. Compared to the control group, those in the intervention gained on average 4 pounds less and were more likely to gain within recommended guidelines. Despite this improvement, however, we did not see any improvement in any of the pregnancy complications.
24 Jan Hypertension in Pregnancy Linked To Early Mortality
MedicalResearch.com Interview with: Dr. Lauren Theilen, MD Obstetrics/Gynecology specialist Salt Lake City, Utah. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Women with a history of hypertensive disease of pregnancy are known to have increased risk of mortality from cardiovascular and other causes. Our study shows that hypertensive disease of pregnancy is strongly associated with deaths due to diabetes, heart disease, and stroke. The association is strongest for early mortality – deaths occurring before age 50 – and life expectancy decreases with increasing number of affected pregnancies.24 Jan Glucose Supplementation Reduced Length of Induced Labor
MedicalResearch.com Interview with: Dr Josianne Paré MD, FRCSC Département d'obstétrique-gynécologie Faculté de médecine et des sciences de la santé de l'université de Sherbrooke 3001 12e avenue Nord, Sherbrooke (Québec), J1H 5N4 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prolonged labor is a significant cause of maternal and fetal morbidity and very few interventions are known to shorten labor course. Skeletal muscle physiology suggests that glucose supplementation might improve muscle performance in case of prolonged exercise and this situation is analogous to the gravid uterus during delivery. Therefore, it seemed imperative to evaluate the impact of adding carbohydrate supplements on the course of labor. Accordingly, we conducted a single centre prospective double-blind randomized-controlled trial comparing the use of parental IV of dextrose 5% with normal saline to normal saline in induced-nulliparous women. A total of 193 patients (96 in the dextrose with normal saline [NS+D] group and 97 in the normal saline group [NS] were analysed in the study. The median total duration of labor was 76 minutes shorter in the NS+D group (499 versus 423 minutes, p = 0.024) than in the NS group. There was no difference in the rate of caesarean section, instrumented delivery, APGAR score or arterial cord pH.20 Jan Link Between Antidepressants During Pregnancy and Birth Defects

Unfortunately, the majority of the data available to council pregnant women is outdated and medical practice has significantly changed since their publication.17 Jan Effects of Delayed Vs Early Umbilical Cord Clamping on Infant Anemia
MedicalResearch.com Interview with:
Dr. Ola Andersson MD, PhD
Uppsala University,
Uppsala, Sweden
MedicalResearch.com: What is the background for this study?
Response: Anemia affects over 40% of all children under 5 years of age in the world. Anemia can impinge mental and physical performance, and is associated with long-term deterioration in growth and development. Iron deficiency is the reason for anemia in approximately 50% of the children.is. When clamping of the umbilical cord is delayed, ie after 3 minutes, iron deficiency up to 6 months of age can be prevented, but it has not been shown to prevent iron deficiency or anemia in older infants.
At birth, approximately 1/3 of the child's blood is in the placenta. If clamping of the umbilical cord is done immediately (early cord clamping), the blood will remain in the placenta and go to waste (or can be stored in stem cell banks). If instead clamping is postponed for 3 minutes, most of the blood can flow back to the child as an extra blood transfusion, consisting of about one deciliter (1/2 cup) of blood, equivalent to about 2 liters (half a US gallon) of an adult. A blood donor leaves 0.4-0.5 liters of blood.
Blood contains red blood cells that contain hemoglobin. Hemoglobin carries oxygen to the tissues of the body. Hemoglobin contains a lot of iron, and the extra deciliter of blood may contain iron that corresponds to 3-4 months of the need for an infant.
The World Health Organization (WHO) recommends umbilical cord clamping at 1 minute or later, American College of Obstetricians and Gynecologists (ACOG) recommends umbilical cord clamping at 30-60 seconds or later.

MedicalResearch.com: What is the background for this study?
Response: Neural tube defects, where the brain or spinal cord do not develop properly in a baby, can occur early in pregnancy, even before a woman knows she is pregnant. Taking folic acid before and during pregnancy can help protect against neural tube defects. Most women do not get enough folic acid in their diets, so most clinicians recommend that any woman who could become pregnant take a daily folic acid supplement.
09 Jan C-Section Rate Varies Across China from 4% to 64%
MedicalResearch.com Interview with: Jianmeng Liu, PhD, MD Professor in Epidemiology and Biostatistics Director, Institute of Reproductive and Child Health/key Laboratory of Reproductive Health Ministry of Health Director, Office for National Maternal and Child Health Statistics of China Peking University Health Science Center Beijing, China MedicalResearch.com: What is the background for this study? Response: Cesarean overuse can jeopardize maternal and child health. It has been widely concerned that cesarean rate in China is at an extremely high level. Concerns about “alarming” rates increased after a World Health Organization (WHO) report that 46.2% of births were delivered by cesarean in 2007-2008, based on analysis of deliveries in 21 hospitals of 3 provinces of China. Since 2002, reducing the cesarean rate has been a national priority, and a variety of policies, programs and activities have emerged at both the central and local governments. Previous national estimates of cesarean rates have been based on surveys with limited geographical coverage. Given the marked diversity of geography, economy, and life circumstances throughout China, survey estimates are likely to be sensitive to the area sampled. By analyzing county-level national data on cesarean rates that have been collected since 2008, this study aimed to determine the overall rate and change in rate of cesarean deliveries, examine geographic variation, and, in areas where declines occurred, assess changes in maternal and perinatal mortality.06 Jan High Outdoor Heat Early in Pregnancy May Raise Risk of Congenital Heart Defects

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: We carried out this study because congenital heart defects take a large share of birth defects, but not much is known on its risk factors.
In previous research, we found that very high temperatures in the summer were associated with a greater risk of stillbirth. We sought to determine whether elevated outdoor heat could also be linked with congenital heart defects in a sample of about 700,000 pregnancies.

MedicalResearch.com: What is the background for this study?
Response: About 1 in 5 pregnant women in the United States is obese. Other studies have looked at mothers’ obesity in terms of children’s development, but no U.S. studies have looked at whether there might be a contribution from the father’s weight.
MedicalResearch.com: What are the main findings?
Response: One of the main findings of this study is that maternal obesity is associated with a delay in fine motor skill-- the ability to control movement of small muscles, such as those in the fingers and hands. Paternal obesity is associated with a delay in personal-social skills including the way the child interacts with others. Having both a mother and a father with severe obesity (BMI≥35) was associated with a delay in problem solving ability.
22 Dec Study Supports Mesh Surgery for Incontinence But Not for Bowel or Bladder Prolapse
MedicalResearch.com Interview with: Dr Rachael Wood PhD Consultant in Public Health Medicine - women and children's health NHS National Services Scotland Information Services Division Edinburgh MedicalResearch.com: What is the background for this study? Response: Mesh surgery for female stress urinary incontinence and pelvic organ prolapse is currently controversial. Mesh surgery was introduced to overcome recognised limitations of traditional, non-mesh, surgery for these conditions, in particular extensive surgery and long hospital stays for incontinence and high failure/recurrence rates for prolapse. Mesh surgery may therefore offer additional benefits over traditional surgery. Mesh surgery may also carry additional risks however, with patient advocacy groups highlighting cases of severe, long term, mesh-related complications in some women who have undergone mesh surgery. We therefore used routinely available, population based hospital discharge records from Scotland to identify women having mesh and non-mesh procedures for incontinence and prolapse. We then followed the women up for up to 5 years to assess how often they were readmitted for complications or further incontinence or prolapse surgery.21 Dec Study Finds No Clear Benefit of Mesh For Prolapse Surgery

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Prolapse is a condition that affects up to half of all women after childbirth. Women notice a bulge or discomfort in their vaginas due to pressure from the bladder, bowel or womb moving downwards. Women who have surgery for their prolapse have a 3 in 10 chance of needing at least one more operation, so the success rate is not great. Gynaecologists hoped that by reinforcing their repairs the success rate would get better.
PROSPECT was a pragmatic, multicentre randomised controlled trial conducted in 35 centres across the UK. Women undergoing their first operation for prolapse were randomised to having a standard repair of the front or back wall of the vagina, or a repair reinforced by synthetic non-absorbable mesh, or a biological graft.
We found that, in contrast to previous research, women were just as likely to be cured after standard surgery rather than reinforced repairs. They were just as likely to have other symptoms such as bladder or sexual problems, and other adverse effects such as infection, bleeding or pain.
However, about 1 in 10 of the women who had mesh did have mesh exposure when a small portion of the mesh becomes visible through the vaginal wall. Although many women did not have symptoms, about half of those women needed a small operation to remove or bury the exposed mesh.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Our research was a prospective study in which pregnant women in Rio de Janeiro who developed a rash in the last 5 days between the end of 2015 to mid 2016 were screened for possible infection with Zika virus by a special molecular test (PCR) which looked for the virus in blood or urine. Women who were found to have Zika virus in either blood, urine or both were followed throughout time to look for pregnancy and infant outcomes. We also followed women who had a negative PCR test for Zika as a comparison group. By July 2016, we had outcomes known for 125 Zika affected pregnancies, of these 58 had abnormal outcomes, with 9 fetal losses and 49 babies who had abnormal findings on physical exam or brain imaging, all consistent with neurologic abnormalities. This meant 46% of the pregnant women in our study had an abnormal pregnancy outcome, and 42% of live birth infants were found to have an abnormality in the first few months of life.
