Abstract STUDY QUESTION For donor oocyte recipients, are birth outcomes superior for fresh versus frozen embryos? SUMMARY ANSWER Among fresh donor oocyte recipients, fresh embryos are associated with better birth outcomes when compared with frozen embryos. WHAT IS KNOWN ALREADY Frozen embryo transfer (ET) with vitrification has been associated with improved pregnancy rates, but also increased rates of large for gestational age infants. Donor oocyte recipients represent an attractive biological model to attempt to isolate the impact of embryo cryopreservation on IVF outcomes, yet there is a paucity of studies in this population. STUDY DESIGN, SIZE, DURATION A retrospective cohort of the US national registry, the Society for Assisted Reproductive Technology Clinic Outcome Reporting System, of IVF cycles of women using fresh donor oocytes resulting in ET between 2013 and 2015. Thawed oocytes were excluded. PARTICIPANTS/MATERIALS, SETTINGS, METHODS Good obstetric outcome (GBO), defined as a singleton, term, live birth with appropriate for gestational age birth weight, was the primary outcome measure. Secondary outcomes included live birth, clinical pregnancy, spontaneous abortion, preterm birth, multiple births and gestational age-adjusted weight. Outcomes were modeled using the generalized estimating equation approach. MAIN RESULTS AND THE ROLE OF CHANCE Data are from 25 387 donor oocyte cycles, in which 14 289 were fresh and 11 098 were frozen ETs. A GBO was 27% more likely in fresh ETs (26.3%) compared to frozen (20.9%) (adjusted risk ratio 1.27; 95% confidence interval (CI) 1.21–1.35; P < 0.001). Overall, fresh transfer was more likely to result in a live birth (55.7% versus 39.5%; adjusted risk ratio 1.21; 95% CI 1.18–1.26; P < 0.001). Among singleton births, there was no difference in gestational age-adjusted birth weight between groups. LIMITATION, REASONS FOR CAUTION Our cohort findings contrast with data from autologous oocytes. Prospective studies with this population are warranted. WIDER IMPLICATIONS OF THE FINDINGS Among donor oocyte recipients, fresh ETs may be associated with better birth outcomes. Reassuringly, given its prevalent use, modern embryo cryopreservation does not appear to result in phenotypically larger infants. STUDY FUNDING/COMPETING INTEREST(S) None.

ObjectivesDengue is the most common viral mosquito-borne disease, and women of reproductive age who live in or travel to endemic areas are at risk. Little is known about the effects of dengue during pregnancy on birth outcomes. The objective of this study is to examine the effect of maternal dengue severity on live birth outcomes.Design and settingWe conducted a population-based cohort study using routinely collected Brazilian data from 2006 to 2012.ParticipatingWe linked birth registration records and dengue registration records to identify women with and without dengue during pregnancy. Using multinomial logistic regression and Firth method, we estimated risk and ORs for preterm birth (<37 weeks’ gestation), low birth weight (<2500 g) and small for gestational age (<10thcentile). We also investigated the effect of time between the onset of the disease and each outcome.ResultsWe included 16 738 000 live births. Dengue haemorrhagic fever was associated with preterm birth (OR=2.4; 95% CI 1.3 to 4.4) and low birth weight (OR=2.1; 95% CI 1.1 to 4.0), but there was no evidence of effect for small for gestational age (OR=2.1; 95% CI 0.4 to 12.2). The magnitude of the effects was higher in the acute disease period.ConclusionThis study showed an increased risk of adverse birth outcomes in women with severe dengue during pregnancy. Medical intervention to mitigate maternal risk during severe acute dengue episodes may improve outcomes for infants born to exposed mothers.

BackgroundThere are few published studies evaluating the impact of perinatal residence change on infant outcomes and whether these associations differ by socioeconomic status.MethodsWe conducted a population-based cohort study using Washington State birth certificate data from 2007 to 2014 to assess whether women who moved during the first trimester of pregnancy (n=28 011) had a higher risk of low birth weight, preterm birth and small for gestational age than women who did not move during the first trimester (n=112 367). ‘Non-first-trimester movers’ were frequency matched 4:1 to movers by year. We used generalised linear models to calculate risk ratios and risk differences adjusted for maternal age, race, marital status, parity, education, smoking, income and insurance payer for the birth. We also stratified analyses by variables related to socioeconomic status to see whether associations differed across socioeconomic strata.ResultsMoving in the first trimester was associated with an increased risk of low birth weight (6.4% vs 4.5%, adjusted risk ratio 1.37 (95% CI 1.29 to 1.45)) and preterm birth (9.1% vs 6.4%, adjusted risk ratio 1.42 (95% CI 1.36 to 1.49)) and a slight increased risk of small for gestational age (9.8% vs 8.7%, adjusted risk ratio 1.09 (95% CI 1.00 to 1.09)). Residence change was associated with low birth weight and preterm birth in all socioeconomic strata.ConclusionMoving during the first trimester of pregnancy may be a risk factor for adverse birth outcomes in US women. Healthcare providers may want to consider screening for plans to move and offering support.

AbstractHuman health effects of airborne lower-chlorinated polychlorinated biphenyls (LC-PCBs) are largely unexplored. Since PCBs may cross the placenta, maternal exposure could potentially have negative consequences for fetal development. We aimed to determine if exposure to airborne PCB during pregnancy was associated with adverse birth outcomes. In this cohort study, exposed women had lived in PCB contaminated apartments at least one year during the 3.6 years before conception or the entire first trimester of pregnancy. The women and their children were followed for birth outcomes in Danish health registers. Logistic regression was performed to estimate odds ratios (OR) for changes in secondary sex ratio, preterm birth, major congenital malformations, cryptorchidism, and being born small for gestational age. We performed linear regression to estimate difference in birth weight among children of exposed and unexposed mothers. All models were adjusted for maternal age, educational level, ethnicity, and calendar time. We identified 885 exposed pregnancies and 3327 unexposed pregnancies. Relative to unexposed women, exposed women had OR 0.97 (95% CI 0.82, 1.15) for secondary sex ratio, OR 1.13 (95% CI 0.76, 1.67) for preterm birth, OR 1.28 (95% CI 0.81, 2.01) for having a child with major malformations, OR 1.73 (95% CI 1.01, 2.95) for cryptorchidism and OR 1.23 (95% CI 0.88, 1.72) for giving birth to a child born small for gestational age. The difference in birth weight for children of exposed compared to unexposed women was − 32 g (95% CI—79, 14). We observed an increased risk of cryptorchidism among boys after maternal airborne LC-PCB exposure, but due to the proxy measure of exposure, inability to perform dose–response analyses, and the lack of comparable literature, larger cohort studies with direct measures of exposure are needed to investigate the safety of airborne LC-PCB exposure during pregnancy

Abstract Study question Do stage and morphology of the competent blastocyst associate with initial hCG rise, gestational age, preterm birth, child birth weight, length, and child sex? Summary answer Higher stage, TE- and ICM-scores associated with higher hCG-rise; ICM- and TE-scores associated with length at birth, and higher stage and TE-score associated with boys. What is known already Many studies have focused on the developmental stage and morphology of the blastocysts in order to find biomarkers of competence to improve the efficacy of assisted reproduction technology treatment. In contrast, the associations between blastocyst assessment score parameters (individually or by combined score) and perinatal outcome have only been reported in few and smaller single center studies, and conflicting results have been presented. In the present study, we focused on the in vitro cultured blastocyst leading to a live birth and how the stage and morphology of these competent blastocysts relate to implantation and birth outcomes. Study design, size, duration Multicenter historical cohort study based on exposure (blastocyst stage (1-6) and morphology (trophectoderm (TE) and inner cell mass (ICM): A,B,C)) and outcome data (serum human chorionic gonadotrophin (hCG), gestational age, preterm birth, child weight, length, and sex) from women undergoing single blastocyst transfer resulting in singleton pregnancy and birth. Data from 16 private and university-based facilities for clinical services and research from 2014 to 2018 was included. Participants/materials, setting, methods 7246 women, who underwent ovarian stimulation or Frozen-thawed-Embryo-Transfer with single blastocyst transfer resulting in singleton pregnancy were identified. Linking to the Danish Medical Birth Registry resulted in a total of 4842 women with live birth being included. Initial serum hCG value (IU/L) (11 days after transfer), gestational age (days), preterm birth (%) child weight (grams), length (cm) and sex. The analyses were adjusted for female age, BMI, smoking, center, diagnosis, parity, gestational age and sex. Main results and the role of chance Higher mean initial hCG was consistently positively associated with higher developmental stage (p &lt; 0.001), TE (p &lt; 0.001) and ICM score (p = 0.02); for stage 6, TE (A) and ICM (A): 508.4, 436.5 and 428.5 IU/L, respectively. No differences between blastocyst morphology (stage, TE, ICM), gestational age (mean 276.6 days), preterm birth (8.3%) and birth weight (mean 3461.7 gram) were statistically significant. While stage showed no association with length at birth (mean 51.6 cm), length at birth between blastocysts with a TE score C and a TE score A were statistically significant (mean difference 0.5 cm (0.07;0.83)) as was the length at birth between blastocysts with an ICM score B and C compared to score A, mean differences respectively 0.2 cm (0.02;0.31) and 0.5 cm (0.03;0.87). Stage and TE, but not ICM were associated with the sex of the child. Blastocysts transferred with stage score 5 compared to blastocysts transferred with score 3 had a 33% increased probability of being a boy (OR 1.33 (1.08;1.64)). Further, TE score B blastocysts compared to TE score A blastocysts had a 28% reduced probability of being a boy (OR 0.72 (0.62;0.82)). Limitations, reasons for caution The assessment scores of the blastocystś stage and morphology were based on subjective evaluation, and information bias may have influenced the results. By adjusting for center, we took the potential variation in scoring between clinics into considerations. Wider implications of the findings Stage and morphology of the competent blastocyst was associated with initial hCG rise suggesting an effect on implantation, which may be used in routine, everyday information to women and couples on the day of blastocyst transfer.

Abstract Background Clostridioides difficile infection (CDI) is the leading cause of healthcare-associated diarrhea and recurs in up to 30% of patients, often requiring readmission. Socioeconomic factors, such as living in a disadvantaged neighborhood may impact readmission but have not been studied. Methods We examined the relationship between neighborhood disadvantage, as measured by the Singh validated area deprivation index (ADI), and 30-day all-cause readmission risk in patients with an index hospital stay with CDI. We analyzed a random 20% sample of national Medicare claims for patients’ initial index hospitalization with a CDI diagnosis in 2014 (n = 19,528) that included each patient’s neighborhood ADI national percentile. The most disadvantaged neighborhoods were categorized as those in the upper 35 percentile, while the least disadvantaged was defined as those in the bottom 65% of national ADI rankings. We evaluated the relationship between ADI percentile and 30-day readmission risk using multivariate logistic regression, controlling for key patient demographics, comorbidities, and hospital/stay characteristics. Results A total of 19,528 patients had an index stay with CDI, 4,899 were readmitted within 30 days. Patients from the most disadvantaged neighborhoods had a higher average rate of readmission compared with those living in the least disadvantaged neighborhoods (28% vs. 24% rate; unadjusted risk ratio = 1.16 [1.10, 1.21]). This relationship held after controlling for confounders. After adjustment, being a resident in the most disadvantaged neighborhoods was associated with a 10% increased risk of readmission (adjusted risk ratio = 1.10 [1.05, 1.16]), which was similar to the effect sizes associated with dual Medicaid-Medicare enrollment status (adjusted risk ratio = 1.09 [1.03, 1.15]) and renal failure (adjusted risk ratio = 1.14 [1.08, 1.21]). Conclusion Living in a disadvantaged neighborhood is associated with an increased 30-day readmission risk similar in magnitude to Medicaid status and renal failure in patients with index hospitalizations of CDI. Future studies should examine whether interventions such as post discharge support and care coordination for patients in disadvantaged neighborhoods may reduce readmissions in this patient population.

Pediatric diarrheal disease remains the second most common cause of preventable illness and death among children under the age of five, especially in low and middle-income countries (LMICs). However, there is limited information regarding the role of food in pathogen transmission in LMICs. For this study, we examined the frequency of enteric pathogen occurrence and co-occurrence in 127 infant weaning foods in Kisumu, Kenya, using a multi-pathogen PCR diagnostic tool, and assessed household food hygiene risk factors for contamination. Bacterial, viral, and protozoan enteric pathogen DNA and RNA were detected in 62% of the infant weaning food samples collected, with 37% of foods containing more than one pathogen type. Multivariable generalized linear mixed model analysis indicated type of infant food best explained the presence and diversity of enteric pathogens in infant food, while most household food hygiene risk factors considered in this study were not significantly associated with pathogen contamination. Specifically, cow’s milk was significantly more likely to contain a pathogen (adjusted risk ratio = 14.4; 95% confidence interval (CI) 1.78–116.1) and more likely to have higher number of enteric pathogen species (adjusted risk ratio = 2.35; 95% CI 1.67–3.29) than porridge. Our study demonstrates that infants in this low-income urban setting are frequently exposed to diarrhoeagenic pathogens in food and suggests that interventions are needed to prevent foodborne transmission of pathogens to infants.

ABSTRACTBackgroundMaternal diet before and during pregnancy could influence fetal growth and birth outcomes.ObjectiveTwo systematic reviews aimed to assess the relationships between dietary patterns before and during pregnancy and 1) gestational age at birth and 2) gestational age- and sex-specific birth weight.MethodsLiterature was searched from January, 1980 to January, 2017 in 9 databases including PubMed, Embase, and Cochrane. Two analysts independently screened articles using predetermined inclusion and exclusion criteria. Data were extracted from included articles and risk of bias was assessed. Data were synthesized qualitatively, a conclusion statement was drafted for each question, and evidence supporting each conclusion was graded.ResultsOf the 9103 studies identified, 11 [representing 7 cohorts and 1 randomized controlled trial (RCT)] were included for gestational age and 21 (representing 19 cohorts and 2 RCTs) were included for birth weight. Limited but consistent evidence suggests that certain dietary patterns during pregnancy are associated with a lower risk of preterm birth and spontaneous preterm birth. These protective dietary patterns are higher in vegetables; fruits; whole grains; nuts, legumes, and seeds; and seafood (preterm birth, only), and lower in red and processed meats, and fried foods. Most of the research was conducted in healthy Caucasian women with access to health care. No conclusion can be drawn on the association between dietary patterns during pregnancy and birth weight outcomes. Although research is available, the ability to draw a conclusion is restricted by inconsistency in study findings, inadequate adjustment of birth weight for gestational age and sex, and variation in study design, dietary assessment methodology, and adjustment for key confounding factors. Insufficient evidence exists regarding dietary patterns before pregnancy for both outcomes.ConclusionsMaternal dietary patterns may be associated with a lower preterm and spontaneous preterm birth risk. The association is unclear for birth weight outcomes.

Abstract Introduction: Immature animals exposed to anesthesia display apoptotic neurodegeneration and neurobehavioral deficits. The safety of anesthetic agents in children has been evaluated using a variety of neurodevelopmental outcome measures with varied results. Methods: The authors used data from the Western Australian Pregnancy Cohort (Raine) Study to examine the association between exposure to anesthesia in children younger than 3 yr of age and three types of outcomes at age of 10 yr: neuropsychological testing, International Classification of Diseases, 9th Revision, Clinical Modification–coded clinical disorders, and academic achievement. The authors’ primary analysis was restricted to children with data for all outcomes and covariates from the total cohort of 2,868 children born from 1989 to 1992. The authors used a modified multivariable Poisson regression model to determine the adjusted association of anesthesia exposure with outcomes. Results: Of 781 children studied, 112 had anesthesia exposure. The incidence of deficit ranged from 5.1 to 7.8% in neuropsychological tests, 14.6 to 29.5% in International Classification of Diseases, 9th Revision, Clinical Modification–coded outcomes, and 4.2 to 11.8% in academic achievement tests. Compared with unexposed peers, exposed children had an increased risk of deficit in neuropsychological language assessments (Clinical Evaluation of Language Fundamentals Total Score: adjusted risk ratio, 2.47; 95% CI, 1.41 to 4.33, Clinical Evaluation of Language Fundamentals Receptive Language Score: adjusted risk ratio, 2.23; 95% CI, 1.19 to 4.18, and Clinical Evaluation of Language Fundamentals Expressive Language Score: adjusted risk ratio, 2.00; 95% CI, 1.08 to 3.68) and International Classification of Diseases, 9th Revision, Clinical Modification–coded language and cognitive disorders (adjusted risk ratio, 1.57; 95% CI, 1.18 to 2.10), but not academic achievement scores. Conclusions: When assessing cognition in children with early exposure to anesthesia, the results may depend on the outcome measure used. Neuropsychological and International Classification of Diseases, 9th Revision, Clinical Modification–coded clinical outcomes showed an increased risk of deficit in exposed children compared with that in unexposed children, whereas academic achievement scores did not. This may explain some of the variation in the literature and underscores the importance of the outcome measures when interpreting studies of cognitive function.

Objective: To assess the prevalence of congenital defects and to investigate the maternal and perinatal aspects in relation to the detailed ICD-10 coding of each individual case using The New Born Data base NBBD data collection system under Global surveillance in collaboration with Center for Disease Control CDC, Atlanta and All India Institute of Medical Science AIMS, New Delhi and Bangabandhu Sheikh Mujib Medical University BSMMU as the Focal point of investigation. Methods: All births and terminations of pregnancy beyond 24 weeks with structural and sonographically detectable birth defects from October,2014 to October, 2018 in the Department of Obstetrics and Gynaecology of Bangladesh Medical College and Hospital were carefully scrutinized and detailed information regarding the maternal and associated clinical risk factors were compiled using the NBBD (New Born Birth Defects) surveillance system. Among that period all births (Live birth and still birth) were counted to have a prevalence data of birth defects using the total number of births as the denominator and the number of birth defects as the numerator. Results: The prevalence of detectable birth defects among the 2002 total births (which includes 110 still births) was found to be 4.34% (87/2002 x 100). According to birth defect category using the ICD-10 coding system, 11 broad categories were found. Musculoskeletal deformities Q65-Q79 were the highest (25/87), followed by congenital malformation of the nervous system Q00-Q07(15/87) and congenital malformation of eye, ear, face and neck Q10-Q18(14/87). The birth defects were categorized as isolated, syndrome and sequence; among the 87 cases, 44 were isolated defects, 40 were syndromic / multiple birth defects and 3 were result of Potter sequence. Regarding maternal variables, maternal age<18 years was 23.4%, 18-25 years was 48.93% ,26-33 years was 23.4% and ≥ 34 years was 6.4%; father’s age < 35 yearswas 74.5% and ≥ 35 years 25.5%%, parental consanguinity was present in 4.3% of case. Analyzing the variables relating to labour conditions, majority of pregnancies were singletons 95.7% leaving only 4.3% of pregnancies being Twin pregnancies. Reviewing babies according to gestational age, 69 (73.4%%) of babies were less than 34 weeks and 26.6% remaining were equal to/more than 34 weeks of gestation reflecting a higher frequency of prematurity or pre-term delivery either induced or spontaneous onset. Regarding the mode of delivery, vaginal birth was conducted in approximately 74% of cases and C-Section was performed in remaining cases, the indication of C-section was guided by obstetric causes such as previous C-section and maternal desire for an elective abdominal delivery. Results of the foetal variables by sex distribution showed a significant male predominance (51/87) 51 male, 26 female and 10 ambiguous. Reviewing babies according to gestational age, 64 (73.4%%) of babies were less than 34 weeks and 26.6% remaining were more than 34 weeks of gestation reflecting a higher frequency of prematurity. The studied foetal variable as categorized by weight, as ≤1500gm (extreme low birth weight ELBW) was 23.4%, 1501-2499gm (Low birth weight LBW) was 50% and ≥2500g (Average birth weight) was 26.6 %. The studied foetal variable as categorized by percentage of babies that were born live birth was 87%, 17 % were stillbirth: a significant portion of those terminated late were found macerated. Data was also compiled regarding the following risk factors: Previous history of birth defects/ previous still birth/ previous spontaneous abortions/ terminations for birth defects which did not reveal significant differences. Conclusion: The study notified only the most visible defects in most cases. However, the study is part of an ongoing surveillance program which has incited much alertness among the participants regarding documentation. The prevalence records and the type of defects may help in the expansion of these programs for the development of future preventive strategies.
