Microvillus inclusion disease (MVID) is a rare enteropathy caused by mutations in the MYO5B or STX3 gene. MVID is a disease that is difficult to manage with clinical heterogeneity. Therefore, knowledge about factors influencing MVID morbidity and mortality is urgently needed. Triggered by a recent study that reported a high percentage of preterm births in twelve cases of MVID, we have conducted a comprehensive retrospective study involving 88 cases of MVID with reported gestational ages. We found that moderate to late preterm birth occurred in more than half of all cases, and this was particularly prominent in MYO5B-associated MVID. Preterm birth in MVID counterintuitively correlated with higher birth weight percentiles, and correlated with higher stool outputs and a significantly shorter average survival time. Data from this study thus demonstrate an increased risk of preterm birth in MYO5B-associated MVID, with a clinical impact on morbidity and mortality. Adverse effects associated with preterm birth should be taken into account in the care of children diagnosed with MVID. Documentation of gestational age may contribute to a better prognostic risk assessment in MVID.

Background.Late preterm births constitute the majority of preterm births. However, most evidence suggesting that preterm birth predicts the risk of mental disorders comes from studies on earlier preterm births. We examined if late preterm birth predicts the risks of severe mental disorders from early to late adulthood. We also studied whether adulthood mental disorders are associated with post-term birth or with being born small (SGA) or large (LGA) for gestational age, which have been previously associated with psychopathology risk in younger ages.Method.Of 12 597 Helsinki Birth Cohort Study participants, born 1934–1944, 664 were born late preterm, 1221 post-term, 287 SGA, and 301 LGA. The diagnoses of mental disorders were identified from national hospital discharge and cause of death registers from 1969 to 2010. In total, 1660 (13.2%) participants had severe mental disorders.Results.Individuals born late preterm did not differ from term-born individuals in their risk of any severe mental disorder. However, men born late preterm had a significantly increased risk of suicide. Post-term birth predicted significantly increased risks of any mental disorder in general and particularly of substance use and anxiety disorders. Individuals born SGA had significantly increased risks of any mental and substance use disorders. Women born LGA had an increased risk of psychotic disorders.Conclusions.Although men born late preterm had an increased suicide risk, late preterm birth did not exert widespread effects on adult psychopathology. In contrast, the risks of severe mental disorders across adulthood were increased among individuals born SGA and individuals born post-term.

Abstract Background Despite 15–17 millions of annual births in China, there is a paucity of information on prevalence and outcome of preterm birth. We characterized the outcome of preterm births and hospitalized preterm infants by gestational age (GA) in Huai’an in 2015, an emerging prefectural region of China. Methods Of 59,245 regional total births, clinical data on 2651 preterm births and 1941 hospitalized preterm neonates were extracted from Huai’an Women and Children’s Hospital (HWCH) and non-HWCH hospitals in 2018–2020. Preterm prevalence, morbidity and mortality rates were characterized and compared by hospital categories and GA spectra. Death risks of preterm births and hospitalized preterm infants in the whole region were analyzed with multivariable Poisson regression. Results The prevalence of extreme, very, moderate, late and total preterm of the regional total births were 0.14, 0.53, 0.72, 3.08 and 4.47%, with GA-specific neonatal mortality rates being 44.4, 15.8, 3.7, 1.5 and 4.3%, respectively. There were 1025 (52.8% of whole region) preterm admissions in HWCH, with significantly lower in-hospital death rate of inborn (33 of 802, 4.1%) than out-born (23 of 223, 10.3%) infants. Compared to non-HWCH, three-fold more neonates in HWCH were under critical care with higher death rate, including most extremely preterm infants. Significantly all-death risks were found for the total preterm births in birth weight <  1000 g, GA < 32 weeks, amniotic fluid contamination, Apgar-5 min < 7, and birth defects. For the hospitalized preterm infants, significantly in-hospital death risks were found in out-born of HWCH, GA < 32 weeks, birth weight <  1000 g, Apgar-5 min < 7, birth defects, respiratory distress syndrome, necrotizing enterocolitis and ventilation, whereas born in HWCH, antenatal glucocorticoids, cesarean delivery and surfactant use decreased the death risks. Conclusions The integrated data revealed the prevalence, GA-specific morbidity and mortality rate of total preterm births and their hospitalization, demonstrating the efficiency of leading referral center and whole regional perinatal-neonatal network in China. The concept and protocol should be validated in further studies for prevention of preterm birth.

AbstractObjective:Müllerian anomalies are associated with increased risk of miscarriage, intrauterine growth restriction (IUGR) and preterm birth. While a commonly implicated cause is restricted expansion of endometrial cavity, alternatively it could be due to abnormal placentation. We sought to examine clinical and histopathologic factors associated with preterm delivery in women with Müllerian anomalies.Study design:One hundred and eleven singleton pregnancies in 85 women were analyzed retrospectively. There were 42 pregnancies with bicornaute, 24 with unicornuate, 24 with septate, 19 with didelphys and one each with arcuate and T-shaped uterus. Primary outcomes included gestational age at delivery, placental histopathology, placenta previa and accreta.Results:Twenty-eight (25.2%) of pregnancies were delivered prior to term. Of those, only 14 (50%) were due to preterm labor or preterm premature rupture of membranes (PPROM). Histological evidence of placental malperfusion was present in 22% of all pregnancies and those delivered at an earlier median gestational age [34 (IQR 31–37) vs. 37 weeks (IQR 34–39); P=0.001]. Malperfusion was more common in preterm than in full term births (46% vs. 14%; P=0.04). Conversely, inflammation was not more common in preterm compared to term deliveries (17.9% vs. 16.9%; P=0.89). Five pregnancies had placenta previa, three of which were complicated by accreta.Conclusion:Placental malperfusion, rather than inflammation, was more commonly associated with preterm births in women with uterine anomalies.

Background. Postpartum depression and preterm birth (PTB) are major problems affecting women’s health. PTB has been associated with increased risk of postpartum depressive symptoms (PDS). However, it is unclear if PTB in women with a prior history of PTB is associated with an incremental risk of PDS. This study aims to determine if PTB in women with a prior history of PTB is associated with an incremental risk of PDS. Methods. Data come from the 2009–2011 national Pregnancy Risk Assessment Monitoring System. Study sample included 55,681 multiparous women with singleton live births in the index delivery. Multiple logistic regression was used to examine the association between PTB and PDS. Results. The risk of PDS was 55% higher in women with PTB in both deliveries (aRR = 1.55; 95% CI = 1.28–1.88) and 74% higher in women with PTB in the index delivery only (aRR = 1.74; 95% CI = 1.49–2.05), compared to women with term deliveries. Conclusions. Preterm birth is a risk factor for PDS. PTB in women with a prior history of PTB is not associated with an incremental risk of PDS. Routine screening for PDS should be conducted for all women and closer monitoring should be done for high risk women with PTB.

AbstractPreterm births are prevalent and a leading cause of neonatal death in the United States. Despite the availability of effective interventions, to date there is not a robust and widely applicable test to identify pregnancies at high risk for spontaneous preterm birth (sPTB). Previously, a sPTB predictor based on the ratio of two proteins, IBP4/SHBG, was validated as an accurate predictor of sPTB in the observational study Proteomic Assessment of Preterm Risk (PAPR). Here it is demonstrated that the same predictor threshold associated with 2-fold increased risk of sPTB, namely −1.4, is also statistically significant for predicting elevated risk of sPTB in the observational study Multicenter Assessment of a Spontaneous Preterm Birth Risk Predictor (TreeToP).

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.

Introduction: Children born prematurely are at higher risk of mortality, morbidity, and impaired motor and cognitive development in childhood than prematurely born babies. Aim: To establish the relationship between the corresponding levels of pregnancy-related plasma protein-A (PAPP-A) and the frequency of premature birth. Materials and methods: The study is prospective. The data was collected through monitoring patients through a questionnaire and sonographic examination at 11-13 gestational weeks. The study excluded all known risk factors for preterm birth, such as previous preterm births, pregnant women with gestational diabetes, preeclampsia, hypertension, placenta previa, hydramnion, multiple pregnancies, smoking, structural and chromosomal abnormalities of the fetus and planned preterm birth. The data from the measured values of PAPP-A and the frequency of premature birth in 636 pregnant women were analyzed. Conclusions: PAPP-A levels are a statistically significant factor for preterm birth. It is expected with a 95% probability in the population with PAPP-A values below 0,515 that the cases with premature birth will be from 7 to 14 times more. Pregnant women with PAPP-A level less than 10th per cent are significantly associated with an increased risk of preterm birth.

Premature delivery is the leading cause of perinatal morbidity and mortality of newborns. The article presents the analysis of preterm birth in the perinatal center of Tula region. Depending on the causes of premature birth the author formed three groups. The 1-st group (n=32) included spontaneous preterm births, the 2nd group (n=115) -premature birth as a result of prenatal rupture of membranes, the 3st group (n=180) included preterm births for medical reasons. In all three groups, the demographic data, age, and parity were analyzed. The problem is the development of complex diagnostic techniques for the purpose of prognosis and preventive measures for pregnant women, because at present the obtained results do not allow us to accurately predict a preterm birth and to identify clearly the criteria for their possible development. Reduction of morbidity and mortality in newborns can be achieved through the timely identification of pregnant women at high risk, methods of prevention of preterm birth, quality of treatment and nursing of low-birth-weight infants [1]. This is of paramount importance not only in the formation of a healthy generation from a very early period of their lives and health, but also for the reproductive potential of women in the future [8].

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.

Abstract Introduction Preterm birth-related complications are the leading cause of under-5 mortality globally. Bhutan does not have a reliable preterm birth rate or data regarding outcome of preterm babies. Aim To determine the preterm birth rate at the Jigme Dorji Wangchuck National Referral Hospital (JDWNRH) in Thimphu, Bhutan, and assess their outcomes. Methods All live preterm births at JDWNRH from 1 January 2017 to 31 December 2017 were followed from birth till hospital discharge. Maternal demographic data, pregnancy details and delivery details were collected. Morbidity and mortality information as well as discharge outcome were collected on babies admitted to neonatal intensive care unit (NICU). Results Preterm birth rate among live births was 6.4%. Most mothers were younger than 30 years, housewives and had secondary education. Pregnancy registration rate and adequacy of antenatal visits were high. Most preterm births were singleton and the predominant mode of delivery was cesarean section. More than half of the births were initiated spontaneously, and the male:female ratio was 1.2:1. Most babies were late preterm and low birth weight. Half of them required NICU admission. Overall mortality rate was 11% and 21.6% for admitted preterm neonates. Preterm small-for-gestational-age neonates, and those born after provider-initiated preterm birth had significantly increased risk of mortality. Most preterm neonates were discharged without complications. The rate of extrauterine growth restriction was high. Conclusion This is the first study on the prevalence of preterm births and their outcomes in the largest tertiary-care hospital in Bhutan.
