Author Interviews, MRSA, OBGYNE / 10.01.2014 Interview with: Dr. Andrea Parriott MPH, PhD Department of Epidemiology Fielding School of Public Health University of California Los Angeles What are the main findings of the study? Dr. Parriott:  We wanted to know whether hospital and provider volume (i.e. the number of deliveries performed by each hospital and provider per quarter) and cesarean section rates were predictors of the risk of methicillin-resistant Staphylococcus aureus (MRSA) infection before discharge from the hospital (after delivering a baby). We did not find an association between any of these variables and risk of MRSA infection. (more…)

Author Interviews, OBGYNE / 21.12.2013 Interview with: Jean-Louis Serre EA 2493 ‘Pathologie Cellulaire and Génétique, de la Conception à la Naissance’, Université de Versailles, Saint Quentin en Yvelines, France SFGH (Société Française de Génétique Humaine), Villejuif, France and Jean-Pierre Siffroi Commission de Génétique, Fédération Française des CECOS, UMR S933 INSERM/Université Pierre et Marie Curie (UPMC), Paris, France What are the main findings of the study? Answers:
  • Anonymous sperm donation may lead to unions between relatives, especially between half-siblings and to an increase of both consanguinity and the frequencies of recessive diseases. We made an evaluation of the actual consequences of anonymous sperm donation in France and we concluded that they can be considered as negligible when compared to those due to false paternities, four times higher.
  • The risk of inadvertent unions between half-sibs is often advocated and we showed that it may be estimated to as few as one case every 10 years. Consequently, the main level of consanguinity in the French population is not modified and unions between first cousins within the sub-population from Mediterranean origin remain the main source of consanguinity.

Rada K. Dagher, Ph.D. Assistant Professor, University of Maryland School of Public Health Department of Health Services Administration College Park, MD Interview with: Rada K. Dagher, Ph.D. Assistant Professor, University of Maryland School of Public Health Department of Health Services Administration College Park, MD 20742 What are the main findings of the study? Dr. Dagher: The main finding of this study is that taking leave from work up to six months after childbirth is associated with a decrease in maternal postpartum depressive symptoms; thus longer maternity leaves may protect against the risk of postpartum depression. We conclude that the 12 week leave duration provided by the Family and Medical Leave Act (FMLA) of 1993 may not be sufficient for women who are at risk or experiencing postpartum depression. Moreover, the unpaid nature of the FMLA makes it harder for mothers with limited financial means to take longer leaves; thus, many of these mothers may have to take leaves that are much shorter in duration than 12 weeks.

Author Interviews, NEJM, OBGYNE / 06.12.2013 Interview with: Aniket D. Kulkarni, M.B., B.S., M.P.H Women's Health and Fertility Branch Centers for Disease Control and Prevention Atlanta, Georgia What are the main findings of the study? Dr. Kulkarni: Our study estimates the contribution of fertility treatments and natural conception to multiple births. Fertility treatments include IVF and non-IVF treatments. Non-IVF treatments primarily include ovulation induction and ovarian stimulation coupled with timed intercourse or intrauterine insemination (IUI). All estimated proportions were adjusted for maternal age which makes this study unique. The incidence of twin births nearly doubled and the incidence of triplet and higher-order births quadrupled over the last 4 decades. Our study estimates that by 2011, a total of 36% of twin births and 77% of triplet and higher-order births resulted from conception assisted by fertility treatments, after adjusting for maternal age. After initial increase, the incidence of triplet and higher order births decreased by 29% from 1998 to 2011. The decrease in triplet and higher order births has coincided with a 70% reduction in the transfer of 3 or more embryos during IVF and a 33% decrease in the proportion of triplet and higher order births attributable to IVF. The decline in the number of embryos transferred during IVF became possible due to monitoring of ART treatments and outcomes and the work of professional societies, which have repeatedly revised practice guidelines to include recommendations for lowering the number of embryos transferred. In contrast, non-IVF fertility treatments of ovulation induction and ovarian stimulation are estimated to contribute the increasing number of multiple births. Hence there is a need for surveillance of births from non-IVF fertility treatments. (more…)

Alastair Sutcliffe M.D., Ph.D. From the Institute of Child Health University College  Interview with: Alastair Sutcliffe M.D., Ph.D. From the Institute of Child Health University College London What are the main findings of the study?   Dr. Sutcliffe: Good NEWS for couples who need assisted conception. All the births (106,000) from Great Britain over 18 years were linked to the National Childhood Cancer Registry from the Human Fertilisation and Embryology Authority (which has recorded all births sine 1991 by law.)Those children who showed up on both registries, had IVF conception and childhood cancer. We predicted the number we would expect from the known national childhood cancer rates. We found ALMOST IDENTICAL rates 108 in our group and 109 predicted. NO INCREASED RISK OF CANCER AFTER IVF CONCEPTION IN OFFSPRING. (more…)

Dr. Stordal: Mothers who used iron supplementation during pregnancy had an increased risk for having children with a diagnosis of celiac disease. This association was not caused by maternal anemia during pregnancy, anemia was not a predictor of celiac disease in the offspring. The risk for celiac disease when the mother had used the highest doses and for the longest period. (more…)

Dr. Jennifer Fay Kawwaas MD Department of Gynecology and Obstetrics Emory University School of Medicine, Atlanta, GA, Interview with: Dr. Jennifer Fay Kawwaas MD Department of Gynecology and Obstetrics Emory University School of Medicine, Atlanta, GA, USA What are the main findings of the study? Dr. Kawwaas: Using CDC National ART Surveillance System (NASS) data, we found an increasing trend from 2000 to 2010 in the number of donor egg cycles performed annually and in the percentage of donor cycles that resulted in a good outcome, defined as delivery of a full term infant weighing more than 5.5lbs. Donor and recipient ages remained relatively stable at 28 and 41, respectively, over the 11-year period. Elective single embryo transfer is recommended when the donor is under 35 years old, regardless of recipient’s age; transfer of a single day 5 embryo was associated with an increased chance of good perinatal outcome. Tubal or uterine factor infertility and non-Hispanic Black race were associated with a lower chance of good perinatal outcome. (more…)

Prof Sally K Tracy DMid Midwifery and Women's Health Research Unit University of Sydney, Royal Hospital for Women Randwick, NSW, Interview with: Prof Sally K Tracy DMid Midwifery and Women's Health Research Unit University of Sydney, Royal Hospital for Women Randwick, NSW, Australia What are the main findings of the study? Prof. Tracy: We recruited 1748 pregnant women, of all risk types, from two tertiary teaching hospitals in different states in Australia and allocated them to receive either caseload midwifery care (871) or standard maternity care (877). The study found more women in caseload midwifery experienced an unassisted vaginal birth without pharmacological analgesia, and fewer women experienced an elective caesarean. While the trial findings did not show a statistically significant difference in the rate of caesarean sections between either group, the overall rate fell by more than 20 percent from pre-trial levels. Newborn infants in both groups achieved similar physical assessment scores (Apgar scores). A slightly lower number of pre-term births and neonatal intensive care admissions among the midwifery caseload group was not statistically significant. Important secondary findings of the study include:
  • 30 percent more spontaneous onset of labour
  • less induction of labour
  • less severe blood loss, and
  • stronger likelihood of breastfeeding at discharge from hospital.
These small differences accounted for an overall difference of AU$566.74 less with caseload midwifery than with standard care. Caseload midwifery appeared to alter some of the pathways that recurrently contribute to increased obstetric intervention.  Having this level of continuity of care works on the assumption that women will labour more effectively, need to stay in hospital less time and feel a stronger sense of satisfaction and personal control if they have the opportunity to get to know their midwife at the beginning of pregnancy.

Dr. Garfield: Unnecessary admissions and treatments for “threatened preterm labor” are still part of everyday clinical practice and contribute to exploding healthcare costs. This happens despite substantial evidence that measuring CL by trans-vaginal ultrasound can help to avoid needless interventions due to the high negative predictive values of this test. (more…)
Author Interviews, Heart Disease, OBGYNE / 18.07.2013 Interview with Prof. Eyal Sheiner MD PhD Senior Obstetrician

Soroka Medical Center, Israel What are the main findings of the study? Dr. Sheiner: The study was aimed to investigate whether a history of preterm delivery (PTD) poses a risk for subsequent maternal long-term cardiovascular morbidity. During the study period 47,908 women met the inclusion criteria; 12.5% (n=5992) patients delivered preterm. During a follow-up period of more than ten years, patients with PTD had higher rates of simple as well as complex cardiovascular events and higher rate of total cardiovascular related hospitalizations. A linear association was found between the number of previous PTD and future risk for cardiovascular hospitalizations (5.5% for two or more PTD, 5.0% for one PTD vs. 3.5% in the comparison group; P<0.001). The association remained significant for spontaneous vs. induced PTD and for early (<34 weeks) as well as late (34-36+6 weeks) PTD. In a Cox proportional hazards model that adjusted for pregnancy confounders such as labor induction, diabetes mellitus, preeclampsia and obesity, PTD was independently associated with cardiovascular hospitalizations (adjusted HR 1.4, 95% CI 1.2-1.6).

Anemia, Author Interviews, BMJ, OBGYNE, Pediatrics / 04.07.2013 Interview with Batool Haider, MD, MS, DSc candidate Departments of Epidemiology and Nutrition School of Public Health Harvard University Anaemia, prenatal iron use, and risk of adverse pregnancy outcomes: systematic review and meta-analysis What are the main findings of the study? Dr. Haider: The main findings of the study are that iron use in the prenatal period increased maternal mean haemoglobin concentration by 4.59 (95% confidence interval 3.72 to 5.46) g/L compared with controls and significantly reduced the risk of anaemia (relative risk 0.50, 0.42 to 0.59), iron deficiency (0.59, 0.46 to 0.79), iron deficiency anaemia (0.40, 0.26 to 0.60), and low birth weight (0.81, 0.71 to 0.93). The effect of iron on preterm birth was not significant (relative risk 0.84, 0.68 to 1.03). Analysis of cohort studies showed a significantly higher risk of low birth weight (adjusted odds ratio 1.29, 1.09 to 1.53) and preterm birth (1.21, 1.13 to 1.30) with anaemia in the first or second trimester. Exposure-response analysis indicated that for every 10 mg increase in iron dose/day, up to 66 mg/day, the relative risk of maternal anaemia was 0.88 (0.84 to 0.92) (P for linear trend<0.001). Birth weight increased by 15.1 (6.0 to 24.2) g (P for linear trend=0.005) and risk of low birth weight decreased by 3% (relative risk 0.97, 0.95 to 0.98) for every 10 mg increase in dose/day (P for linear trend<0.001). Duration of use was not significantly associated with the outcomes after adjustment for dose. Furthermore, for each 1 g/L increase in mean haemoglobin, birth weight increased by 14.0 (6.8 to 21.8) g (P for linear trend=0.002); however, mean haemoglobin was not associated with the risk of low birth weight and preterm birth. No evidence of a significant effect on duration of gestation, small for gestational age births, and birth length was noted. (more…)
Author Interviews, Nutrition, OBGYNE, Pediatrics / 17.03.2013 Interview with : Verena Sengpiel, researcher Institute of Clinical Sciences, Sahlgrenska Academy University of Gothenburg What are the main findings of the study? Response: 1. Coffee, but not caffeine, consumption was associated with marginally increased gestational length but not with the risk of spontaneous preterm delivery. 2. Caffeine intake was consistently associated with decreased birth weight and increased odds of SGA (small for gestational age). This might have clinical implications as even caffeine consumption below the recommended maximum (200 mg/d in the Nordic countries and USA, 300 mg/d according to WHO) was associated with increased risk for SGA.
