Background: The pregnancy outcomes are influenced by the inter pregnancy intervals. Both short and long inter pregnancy intervals are known to adversely affect the mother and the baby. The main aim of birth spacing was to achieve ideal inter pregnancy intervals and thus to decrease maternal, neonatal morbidity and mortality.Methods: It is a prospective observational study. In this study, about 500 gravida 2 women who has delivered vaginally in the index pregnancy, with gestational age more than 28 weeks of gestation and with known interpregnancy interval were included in the study. They followed up to to delivery and occurance of preterm births in relation to maternal characteristics and interpregnancy interval were analysed.Results: Our study showed that Inter pregnancy intervals of 18-24 months were found to have the least number of preterm births when compared to intervals <18 months and >24 months. This association was found to be statistically significant (p value, Pearson chi square 0.0008). This relationship between inter pregnancy intervals and preterm births persisted when stratified according to maternal age, education, residence and BMI.A previous preterm birth was associated with increased risk of recurrent preterm birth (p value -0.034) and was statistically significant. The history of PROM in present pregnancy associated with preterm birth (p value -0.001) and association was statistically significant.Conclusions: From this study it was found that the 18-24 months birth to pregnancy interval is associated with the least incidence of preterm births.

Adverse Pregnancy

Preterm births are the leading cause of neonatal death in the United States. Previously, a spontaneous preterm birth (sPTB) predictor based on the ratio of two proteins, IBP4/SHBG, was validated as a predictor of sPTB in the Proteomic Assessment of Preterm Risk (PAPR) study. In particular, a proteomic biomarker threshold of −1.37, corresponding to a ~two-fold increase or ~15% risk of sPTB, significantly stratified earlier deliveries. Guidelines for molecular tests advise replication in a second independent study. Here we tested whether the significant association between proteomic biomarker scores above the threshold and sPTB, and associated adverse outcomes, was replicated in a second independent study, the Multicenter Assessment of a Spontaneous Preterm Birth Risk Predictor (TREETOP). The threshold significantly stratified subjects in PAPR and TREETOP for sPTB (p = 0.041, p = 0.041, respectively). Application of the threshold in a Kaplan–Meier analysis demonstrated significant stratification in each study, respectively, for gestational age at birth (p < 001, p = 0.0016) and rate of hospital discharge for both neonate (p < 0.001, p = 0.005) and mother (p < 0.001, p < 0.001). Above the threshold, severe neonatal morbidity/mortality and mortality alone were 2.2 (p = 0.0083,) and 7.4-fold higher (p = 0.018), respectively, in both studies combined. Thus, higher predictor scores were associated with multiple adverse pregnancy outcomes.

AbstractBackgroundWe aimed to study the maternal characteristics and obstetric and neonatal outcomes in pregnant mothers with chronic hypertension (CHTN) compared to non-CHTN.MethodsThe study was a population-based cohort study, and a PEARL-Peristat Study (PPS) for the year of 2017. There were 20,210 total births including 19,762 singleton and 448 multiple births. We excluded multiple gestations from the analysis as they differ in fetal growth, duration of gestation and have a higher rate of obstetric and neonatal complications. We compared the maternal characteristics of mothers with pre-existing HTN with non-hypertensive mothers and studied the obstetric and neonatal outcomes including cesarean section, stillbirths, prematurity, macrosomia and postpartum hemorrhage (PPH).ResultsWe identified 223 births of mothers with essential HTN. The overall prevalence of CHTN in our population was 1.1% (223/20,210). In regard to maternal characteristics, women with CHTN were at or above 35 years of age at the time of delivery 58.9% compared to non-CHTN women 18.7%, P-value <0.001. Pre-existing diabetes was found more in women with CHTN 15.1% compared to non-CHTN women 1.9%, P-value <0.001; while obesity was found in 64% of women with CHTN compared to 32.5% in non-CHTN women, P-value <0.001. Preterm birth was noted in 26% compared to 8% in CHTN compared to non-CHTN women, respectively, P-value <0.001. The rate of stillbirth was similar between the two groups, 0.9% compared to 0.6% in CHTN compared to non-CHTN women, respectively, P-value 0.369.ConclusionHypertensive mothers have multiple other comorbidities. When compared to the general population, they are older, parous, diabetic and obese with an increased risk of preterm birth and cesarean deliveries. Lifestyle modification, extensive pre-conceptional counseling and multidisciplinary antenatal care are required for such a high-risk group.

The Impact

Sub-Saharan Africa concentrates the burden of HIV and the highest adolescent fertility rates. However, there is limited information about the impact of the interaction between adolescence and HIV infection on maternal health in the region. Data collected prospectively from three clinical trials conducted between 2003 and 2014 were analysed to evaluate the association between age, HIV infection, and their interaction, with the risk of maternal morbidity and adverse pregnancy and perinatal outcomes in women from southern Mozambique. Logistic regression and negative binomial models were used. A total of 2352 women were included in the analyses; 31% were adolescents (≤19 years) and 29% HIV-infected women. The effect of age on maternal morbidity and pregnancy and perinatal adverse outcomes was not modified by HIV status. Adolescence was associated with an increased incidence of hospital admissions (IRR 0.55, 95%CI 0.37–0.80 for women 20–24 years; IRR 0.60, 95%CI 0.42–0.85 for women >25 years compared to adolescents; p-value < 0.01) and outpatient visits (IRR 0.86, 95%CI 0.71–1.04; IRR 0.76, 95%CI 0.63–0.92; p-value = 0.02), and an increased likelihood of having a small-for-gestational age newborn (OR 0.50, 95%CI 0.38–0.65; OR 0.43, 95%CI 0.34–0.56; p-value < 0.001), a low birthweight (OR 0.40, 95%CI 0.27–0.59; OR 0.37, 95%CI 0.26–0.53; p-value <0.001) and a premature birth (OR 0.42, 95%CI 0.24–0.72; OR 0.51, 95%CI 0.32–0.82; p-value < 0.01). Adolescence was associated with an increased risk of poor morbidity, pregnancy and perinatal outcomes, irrespective of HIV infection. In addition to provision of a specific maternity care package for this vulnerable group interventions are imperative to prevent adolescent pregnancy.

The relation of Zika virus (ZIKV) with microcephaly is well established. However, knowledge is lacking on later developmental outcomes in children with evidence of maternal ZIKV infection during pregnancy born without microcephaly. The objective of this analysis is to investigate the impact of prenatal exposure to ZIKV on neuropsychomotor development in children without microcephaly. We evaluated 274 children including 235 ZIKV exposed and 39 controls using the Bayley-III Scales of Infant and Toddler Development (BSIDIII) and neurological examination. We observed a difference in cognition with a borderline p-value (p = 0.052): 9.4% of exposed children and none of the unexposed control group had mild to moderate delays. The prevalence of delays in the language and motor domains did not differ significantly between ZIKV-exposed and unexposed children (language: 12.3% versus 12.8%; motor: 4.7% versus 2.6%). Notably, neurological examination results were predictive of neurodevelopmental delays in the BSIDIII assessments for exposed children: 46.7% of children with abnormalities on clinical neurological examination presented with delay in contrast to 17.8% among exposed children without apparent neurological abnormalities (p = 0.001). Overall, our findings suggest that relative to their unexposed peers, ZIKV-exposed children without microcephaly are not at considerably increased risk of neurodevelopmental impairment in the first 42 months of life, although a small group of children demonstrated higher frequencies of cognitive delay. It is important to highlight that in the group of exposed children, an abnormal neuroclinical examination may be a predictor of developmental delay. The article contributes to practical guidance and advances our knowledge about congenital Zika.

This study aims to investigate the effects of the three potassium channel genes KCNA1, KCNA2, and KCNV2 on increased susceptibility to epilepsy as well as on responsiveness to antiepileptic drugs (AEDs). The pharmacogenetic and case-control cohort (n = 595) consisted of 296 epileptic patients and 299 healthy individuals. Epileptic patients were recruited from the Pediatric Neurology clinic at the Queen Rania Al Abdullah Hospital (QRAH) in Amman, Jordan. A custom platform array search for genetic association in Jordanian-Arab epileptic patients was undertaken. The MassARRAY system (iPLEX GOLD) was used to genotype seven single nucleotide polymorphisms (SNPs) within three candidate genes (KCNA1, KCNA2, and KCNV2). Only one SNP in KCNA2, rs3887820, showed significant association with increased risk of susceptibility to generalized myoclonic seizure (p-value < 0.001). Notably, the rs112561866 polymorphism of the KCNA1 gene was non-polymorphic, but no significant association was found between the KCNA1 (rs2227910, rs112561866, and rs7974459) and KCNV2 (rs7029012, rs10967705, and rs10967728) polymorphisms and disease susceptibility or drug responsiveness among Jordanian patients. This study suggests that a significant association exists between the KCNA2 SNP rs3887820 and increased susceptibility to generalized myoclonic seizure. However, the present findings indicate that the KCNA1 and KCNV2 SNPs do not influence disease susceptibility and drug responsiveness in epileptic patients. Pharmacogenetic and case-control studies involving a multicenter and multiethnic approach are needed to confirm our results. To improve the efficacy and safety of epilepsy treatment, further studies are required to identify other genetic factors that contribute to susceptibility and treatment outcome.

ABSTRACT Background The impact of fasting on risk of preterm birth during Ramadan is unclear. Objectives We evaluated the association between Ramadan fasting during pregnancy and risk of preterm birth for Arab women in Canada. Methods We analyzed birth certificates from 3,123,508 deliveries in Quebec, Canada, from 1981 to 2017. We identified 78,109 births of Arabic-speaking women and determined if Ramadan occurred during any trimester of pregnancy. We calculated rates of extreme (22–27 wk), very (28–31 wk), and late (32–36 wk) preterm birth and estimated RRs and 95% CIs for the association of Ramadan fasting with risk of preterm birth by pregnancy trimester, using log-binomial regression models adjusted for maternal characteristics. Results Arabic speakers had an overall preterm birth rate of 5.53 per 100 births, but rates varied with timing of Ramadan. Among Arabic speakers, fasting during Ramadan between weeks 15–21 of the second trimester was associated with 1.33 times the risk of very preterm birth relative to no fasting (95% CI: 1.06, 1.68). Between weeks 22 and 27 of the second trimester, fasting during Ramadan was associated with 1.53 times the risk of very preterm birth (95% CI: 1.21, 1.93). Ramadan fasting was not associated with extreme or late preterm birth regardless of the trimester of pregnancy. Conclusions In this study of 78,109 births to Arabic-speaking women in Quebec, Ramadan fasting during the second pregnancy trimester was associated with the risk of very preterm birth. Optimal prenatal education about nutritional needs in the second trimester of pregnancy is recommended.

OBJECTIVES/SPECIFIC AIMS: Clostridium Difficile Infection (CDI), a prevalent cause of diarrhea, is the most notorious hospital-acquired infection, resulting in an alarming mortality and health care utilization rates. Herein, we investigate the impact of cannabis use, which is gaining significant legalization for recreational use, on the risk of CDI. METHODS/STUDY POPULATION: We selected adult records (age ≥ 18 years) from the Nationwide Inpatient Sample 2014, and identified cannabis users and other clinical conditions using ICD-9-CM codes. With multivariate logistic modeling, we generated propensity scores for cannabis users and matched them to non-users in a 1:1 ratio (104,936:104,936). We then estimated the adjusted relative risk (aRR) for having CDI using conditional Possion regression models with generalized estimating equations [SAS 9.4]. RESULTS/ANTICIPATED RESULTS: Among the matched hospitalizations (n=209,872), cannabis usage was associated with a reduced incidence of CDI (505.8[464.7-550.6] vs. 694.9[645.8-747.70] per 100,000 hospitalizations), resulting in a 27% reduced risk of CDI (aRR:0.73[0.65-0.81]; p-value:<0.0001). Non-dependent and dependent cannabis users respectively had 22% and 78% reduced likelihood of CDI when compared to non-cannabis users (0.78[0.69-0.90] & 0.22[0.12-0.40]). Furthermore, dependent users had less risk of CDI compared to non-dependent users (0.28[0.16-0.51]). Comparatively, abusive use of other substances like alcohol and tobacco was associated with increased risk for CDI (1.30[1.13-1.49] & 1.24[1.10-1.40]) DISCUSSION/SIGNIFICANCE OF IMPACT: Unlike alcohol and tobacco abuse which are associated with elevated risk for CDI, cannabis use, is related to a decreased risk of CDI amongst hospitalized patients. Further prospective and molecular mechanistic studies are required to elucidate how cannabis impacts CDI.

Aims: To examine the occurrence of chorioamnionitis and abruption among women who had a spontaneous preterm birth (SPTB), the correlation between clinical and placental findings, and the impact of these complications on neonatal outcome after delivery. Methods: This was a retrospective case-control study conducted between 2008 and 2012 at a single teaching hospital. The study group included all women who had an SPTB (23-36 weeks). Placentas were cultured and underwent histological examination. Results: A total of 478 women were included. The mean gestational age at delivery was 32.6 ± 3.1 weeks. Overall, 260 (54.4%) women had either clinical and/or histological abruption or chorioamnionitis. Clinical chorioamnionitis was diagnosed before birth in 14 (2.9%) women, while histological chorioamnionitis (HCA) in 84 (17.4%). Overall, 38 neonates had infection. Placental cultures were negative in 65.8% (25/38) of these neonates, and in 77.1% (27/38), HCA was ruled out. Logistic regression analysis revealed that neonatal morbidity and mortality were correlated with gestational age at delivery (p = 0.02), not with placental pathology (p = 0.08). Conclusions: Half of the women with PTB had clinical or histological abruption, chorioamnionitis or both. A partial correlation was found between clinical and placental findings. The main determinant of neonatal outcome was gestational age at delivery and not placental findings.

Abstract Abstract 3802 Background and Aim: The impact of the CA on prognosis and transformation into acute myeloid leukemia among pts with low and int-1 risk MDS is not known. The aims of the study were to assess the impact of CA on the natural history of pts with lower risk MDS and to identify factors associated with its development. Methods: We reviewed 721 pts clinical records of low and intermediate risk MDS pts from 2000–2010 and conducted a retrospective analysis of all pts with at least two consecutive cytogenetic analysis (365 patients, 51%). The acquisition of CA was defined by structural change or gain in at least 2 metaphases and loss in 3 metaphases, or otherwise confirmed by FISH. Cox proportional hazards regression models were fit to assess the association between transformation-free survival (TFS) or overall survival (OS) and pt characteristics. The acquisition of CA was fitted in the Cox model as a time-dependent covariate. The association between the acquisition of CA and pt characteristics was assessed through univariate and multiple logistic regression models. Results: CA was detected in 107 pts (29%) after a median follow-up of 34 months (mos). CA was observed in a median number of 4 metaphases (range, 2–30). At diagnosis, 21% and 79% of pts who acquired CA were low-and int-1risk MDS; 50% were diploid, 22% harbored chromosome 5 /7 abnormalities. At the time of acquisition of CA, the median percentage of bone marrow blasts was 4% (range, 0% to 89%), the median WBC, hemoglobin and platelets were 3.1 × 109/L, 9.5 g/dL, and 65 × 109/L, respectively; pts were low, int-1, int-2, and high-risk MDS in 3%, 42%, 26%, 29%, respectively. The median TFS and OS were 31 (95% CI: 27– 37) and 34 (95% CI: 30 – 44) mos respectively. Assessing CA as time-dependent covariate, patients with CA had a worse TFS and OS, with a median TFS and OS of 16 and 18 mos compared to 56 and 60 mos, respectively in pts without CA. Based on the multivariable Cox model and after adjusting for effects of all other covariates, pts who had acquired CA had an increased risk of transformation (HR=1.46; p-value = 0.01) or death (HR=1.50; p-value = 0.01). By multivariate analysis, female pts with prior chemotherapy had an increased risk of developing CA (OR= 5.26; p-value <0.0001). 96 pts had history of previous malignancy treated with chemotherapy +/− radiation therapy. Of those, 34 (35%) patients acquired CA. Median time from previous chemotherapy to the acquisition of CA was 61 mos (range, 11 to 180). Pts previously treated who did not acquire CA had similar outcomes to those who had never been treated and did not develop CA, while those who did develop CA whether they were previously treated or not had worse TFS and OS. Conclusion: CA occurs at a rate of 29% of pts with lower risk MDS, more common among pts with previously treated malignancy, and has a significant impact on TFS and OS, possibly reflecting genomic instability in the natural history of MDS.
