Background Neonates at risk of hypoglycemia are often roomed in with mothers, but there is paucity of literature on the occurrence of hypoglycemia in these exclusively breastfed high-risk neonates. The primary objective was to estimate the incidence of hypoglycaemia in high-risk neonates on exclusive breastfeeding. The secondary objectives were to study the time of presentation, symptoms of hypoglycaemia, and the various maternal and neonatal risk factors. Methods This prospective observational study was carried out in a tertiary care teaching hospital of eastern India between January 2017 and June 2018. All neonates roomed in with mothers with high-risk factors such as low birth weight, preterm, small for gestational age, large for gestational age and infants of diabetic mothers were included. All included neonates were exclusive breastfed and underwent blood glucose monitoring at 2, 6, 12, 24, 48 and 72 h of life using glucometer strips and also whenever clinical features suggested hypoglycaemia. Hypoglycemia was defined as the blood glucose level ≤46 mg/dL. Results Of a total of 250 neonates studied, 52 (20.8%) developed hypoglycaemia in first 72 h. Hypoglycaemia was detected in most at 2 h with the second peak at 48 h of age. Only 8 (3.2%) neonates had symptomatic hypoglycaemia with jitteriness being the commonest symptom, followed by lethargy and poor feeding. Conclusion There is a need to closely monitor the blood glucose levels for at least first 48 h in high-risk neonates roomed in with mothers on exclusive breastfeeding.

Introduction: Transverse relaxation time (T2*) is related to tissue oxygenation and morphology. We aimed to describe T2* weighted MRI in selected fetal organs in normal pregnancies, and to investigate the correlation between fetal organ T2* and placental T2*, birthweight (BW) deviation, and redistribution of fetal blood flow. Methods: T2*-weighted MRI was performed in 126 singleton pregnancies between 23+6- and 41+3-weeks’ gestation. The T2* value was obtained from the placenta and fetal organs (brain, lungs, heart, liver, kidneys, and spleen). In normal BW pregnancies (BW > 10th centile), the correlation between the T2* value and gestational age (GA) at MRI was estimated by linear regression. The correlation between fetal organ Z-score and BW group was demonstrated by boxplots and investigated by analysis of variance (ANOVA) for each organ. Results: In normal BW pregnancies fetal organ T2* was negatively correlated with GA. We found a significant correlation between BW group and fetal organ T2* z-score in the fetal heart, kidney, lung and spleen. A positive linear correlation was demonstrated between fetal organ T2* and outcomes related to placental function such as BW deviation and placenta T2* in all investigated fetal organs except for the fetal liver. In the fetal heart, kidneys, and spleen the T2* value showed a significant correlation with fetal redistribution of blood flow (Middle cerebral artery Pulsatility Index) before delivery. Discussion: Fetal T2* is correlated with BW, placental function, and redistribution of fetal blood flow, suggesting that fetal organ T2* reflects fetal oxygenation and morphological changes related to placental dysfunction.

Breastmilk is the best nutrition to reduce morbidity and mortality among infants with low birth weight (LBW). However, breastfeeding LBW infants during hospitalization is often problematic. Strategies to promote breastfeeding can be done through providing breastfeeding education and support. The purpose of this study was to identify effect of the “SATUPAS” program on breastmilk production, frequency of breastmilk expression, and partial breastfeeding. This study was a randomized controlled trial involving 82 mothers and their LBW infants, which were divided into the intervention group and the control group. Bivariate analysis using the Wilcoxon and Mann Whitney tests showed that there was a significant difference between breastmilk production (p = 0.001), frequency of breastmilk expression (p = 0.001), and partial breastfeeding (p = 0.001) between the control group and the intervention group. This study recommends the implementation of SATUPAS as a strategy to increase breastfeeding of LBW infants undergoing hospitalization.

Premature and low birth weight newborns are at greater risk of developing nosocomial infections, including Candida spp infections. This is a systematic literature review to identify risk factors for developing candidemia in neonates. The search was performed in the VHL, Cochrane, Embase, Pubmed, Scielo, Scopus and Web of Science databases and the terms were: Candidemia, Candidiasis, Candida spp. Invasive Candidiasis, Risk Factors, Infant, Newborn and Neonatology. Meta-analysis was performed for risk factor using Comprehensive Meta Analysis. A total of 2218 articles were identified and 42 papers were included. The main risk factors were: low weight, previous surgery, intubation, mechanical ventilation, central venous catheter, antibiotics and parenteral nutrition. Low birth weight and neonatal units care assistance factors were the main predictors of Candidemia in neonates. Prospective studies are necessary with systematic follow-up during hospitalization to define measures to prevent infection, since retrospective studies have inherent selection and information bias.

Objective In this brief review, the authors focus on the effects of gestational exposures to urban air pollution on fetal development and neonatal outcomes. Source of data In this review the authors used PubMed, Web of Science and SciELO research platforms, analyzing papers from the last 30 years. Summary of the findings Epidemiological and experimental evidence agree that gestational exposure to air pollution in urban increases the risks for low birth weight, preterm birth, congenital malformation, intrauterine growth restriction, and neonatal mortality. Furthermore, exposures are associated with increased risks for preeclampsia, hypertension, gestational diabetes. Conclusions Therefore, it is time for greater involvement and engagement of the health sector in the discussion of public policies that may affect the quality of the environment, and that directly or indirectly impact the health of those who were not yet born.

Research Question Does blastocyst biopsy for preimplantation genetic testing (PGT) increase the risk of adverse maternal and neonatal outcomes? Study design A retrospective cohort study was conducted. A total of 5097 single frozen-thawed blastocyst transfer cycles, including 2061 cycles in the biopsied group and 3036 cycles in the unbiopsied group, from January 2016 to December 2018 were enrolled in our analyses. Maternal and neonatal outcomes were compared between the two groups. Results The live birth rate in the biopsied group (41.1%) was significantly higher than that in the unbiopsied group (35.6%, adjusted OR=1.34 [95% CI: 1.10, 1.63], p=0.003) after adjusting for maternal age, maternal body mass index, gravidity, parity, infertility diagnosis, timing of blastocyst transfer, blastocyst quality, regimen of endometrial preparation, endometrial thickness before transfer, and treatment year. The rates of biochemical pregnancy loss (12.6% vs. 14.6%, adjusted OR=0.64 [0.43, 0.95], p=0.026) and early miscarriage (12.1% vs. 17.3%, adjusted OR=0.49 [0.33, 0.75, p=0.001) were significantly lower in the biopsied group than in the unbiopsied group. No significant differences were found in sex ratio or the risks of hypertensive disorders in pregnancy, diabetes in pregnancy, placenta previa, preterm premature rupture of membranes, low birth weight, very low birth weight, macrosomia, small for gestational age, large for gestational age or birth defects between the two groups. When the subgroup analyses were conducted based on different types of PGT, Similar patterns were found for all types. Conclusion Blastocyst biopsy might not increase the risks of adverse maternal and neonatal outcomes in the short term.

Background There are limited data regarding the risk factors for hyperglycemia in extremely low birth weight infants (ELBWIs). The aim of this observational study was to investigate the incidence of hyperglycemia among ELBWIs during the first 14 days of life and identify independent risk factors for hyperglycemia development. Methods We retrospectively evaluated 55 ELBWIs (32 male infants) between January 2015 and March 2020. Hyperglycemia was diagnosed when the glucose level was ≥180 mg/dL. Demographic and clinical data were extracted from the patients’ medical records. The risk factors associated with the onset of hyperglycemia were identified by Cox proportional hazards regression analysis with variables that had previously been identified as risk factors for hyperglycemia. Results Hyperglycemia developed in 23 patients (41.8%) within the first 14 days of life. Gestational age, chorioamnionitis, postnatal intravenous glucocorticoids, and probiotic type were included in the analysis. The results indicated that hyperglycemia was significantly associated with gestational age (hazard ratio [HR], 0.65; 95% confidence interval [CI], 0.48–0.87; P = 0.004). Further, Bifidobacterium breve (B. breve M-16V) use was related to hyperglycemia in ELBWIs (HR, 2.95; 95% CI, 1.10–7.87; P = 0.031). Conclusion Hyperglycemia was strongly associated with lower gestational age and B. breve M-16V use in our study population. Although probiotic supplementation may be beneficial for preterm infants to reduce the incidence of necrotizing enterocolitis, the dextrin used as an excipient in B. breve M-16V may lead to an undesirable carbohydrate load in ELBWIs.

Objective To analyse a cohort of pregnant patients with systemic lupus erythematosus and compare the outcomes of both the disease and pregnancy with the results of previous studies conducted in the same geographical area. Patients and methods Retrospective cohort study of 37 women with systemic lupus erythematosus (64 pregnancies) followed in a multidisciplinary unit. Comparative study with similar Spanish studies identified after literature search. Results Our cohort was characterized by an older age and by the presence of non-Caucasian patients. Although we found no clinical differences, from the serological point of view our cohort presented a higher frequency of antiphospholipid antibodies. Patients included in this study were treated more frequently with antimalarials and low-dose aspirin. Systemic lupus erythematosus flare frequency was very similar between the different studies, and we did not identify clear predictors for them. Although the rate of live births was similar among studies, the obstetric outcome of our series was better with a very low rate of preeclampsia, preterm birth and low birth weight newborn. The only predictor of adverse obstetric event was age. Conclusions Although changes in the therapeutic attitude and planning of pregnancy in recent years have not had a direct impact on the rate of systemic lupus erythematosus flares during pregnancy, they have meant an improvement in the obstetric results. The introduction of new variables independent of the disease such as age at conception, socio-cultural origin, or the availability of multidisciplinary units should be considered in the results of future studies.

Objectives To examine the association of prenatal cannabis use and adverse infant outcomes in a nationally representative cohort and consider the impact of concurrent cigarette exposure. Study design We conducted a retrospective cohort study on 32 583 new mothers from the 2017-2019 Pregnancy Risk Assessment Monitoring System. Cannabis use was evaluated as a binary variable (use or no use) as well as ordinal categories (no, light, moderate, heavy use). We used multivariable logistic regression to examine the relationship between prenatal cannabis exposure and low birthweight (LBW), preterm birth, and small for gestational age. Results Prenatal cannabis use was associated with significantly greater odds of LBW (aOR, 1.27; 95% CI, 1.05-1.54) and small for gestational age (aOR, 1.35; 95% CI, 1.09-1.68) but not preterm birth. Compared with nonusers, heavy users (weekly or more) were twice as likely to deliver a LBW infant (aOR, 2.07; 95% CI, 1.46-2.94) or small for gestational age infant (aOR, 2.14; 95% CI, 1.38-3.30). When examining combined cannabis and cigarette use, prenatal exposure to both substances increased the likelihood of LBW (aOR, 2.27; 95% CI, 1.71-3.01), preterm birth (aOR, 1.61; 95% CI, 1.12-2.31), and small for gestational age (aOR, 3.29; 95% CI, 2.39-4.55) compared with no use, and the increased odds were greater than for either substance alone. Conclusions Our results suggest that cannabis use during pregnancy may harm fetal development, and recommendations to improve birth outcomes should address co-use of cannabis and tobacco.

AIM: We examined whether timing of known risk factors for schizophrenia may influence the development of schizophrenia with primary negative symptoms. METHOD: This cross-sectional single-centre study in England used a clinical cohort of 167 clozapine-treated schizophrenia patients. Deficit and nondeficit schizophrenia models were used as clinical proxies of patients with and without primary negative symptoms respectively. Patients were assessed using the Schedule for the Deficit Syndrome. We examined previously replicated risk factors (family history of psychosis, advanced paternal age, male gender, birth weight

What is the association between endometrial thickness (EMT) on HCG trigger day and outcomes related to birth weight in fresh IVF and intracytoplasmic sperm injection (ICSI) embryo transfer cycles?A retrospective cohort study of 9273 singleton live births born to women undergoing fresh IVF/ICSI cycles in a single centre between January 2014 and December 2018. Multivariable logistic regression was used to investigate the associations between EMT, low birth weight (LBW) and small for gestational age (SGA). Multivariable-adjusted linear regression models incorporating restricted cubic splines were used to investigate the dose-response relationship between EMT, birth weight and birth weight z-score, respectively. An EMT of 8 mm was set as a reference value.Compared with women with an EMT of 8.0 to14.0 mm the risk of delivering a SGA infant was increased with EMT8.0 mm (adjusted odds ratio [aOR] 1.78, 95% confidence interval [CI] 1.09 to 2.90) and decreased with EMT ≥ 14.0 mm (aOR 0.57, 95% CI 0.35 to 0.93, respectively). Birth weights of infants born to women with an EMT of 8.0 mm compared with women with EMT of 5.0, 6.0, and 7.0 mm were lower by 120 g (95% CI -175 g to -66 g), 80 g (95% CI -116 g to -44 g), and 40 g (95% CI -58 g to -22 g) respectively; infant birth weight z-scores were also decreased by 0.19 (95% CI -0.27 to -0.10), 0.12 (95% CI -0.18 to -0.07) and 0.06 (95% CI -0.09 to -0.03), respectively.A thinner endometrium was associated with lower birth weight and birth weight z-score, and higher risk of SGA. Women with a thin endometrium warrant special attention during pregnancy.

Brush or delta brush is a well-known characteristic waveform in preterm electroencephalograms. However, the longitudinal trajectory of brushes and its association with neurodevelopment remain uncertain.We analyzed the longitudinal incidence of brushes in 36 extremely low birth weight infants without severe brain lesions and its association with neurodevelopment and white matter abnormality. Conventional eight-channel electroencephalograms were recorded at 30, 32, 36, and 40 postmenstrual weeks (PMW). Incidence of brushes was calculated as the sum of brushes from each channel separated by active sleep and quiet sleep. A developmental delay was defined as a developmental quotient of85 assessed at corrected age of 18 months. White matter abnormalities were evaluated with term-equivalent magnetic resonance imaging.The median incidence of brushes (per minute) in 36 infants at PMW 30, 32, 36, and 40 was 16.4, 20.4, 22.5, and 1.8 during active sleep and 7.5, 10.3, 11.5, and 1.7 during quiet sleep, respectively. Among the 36 infants, 14 infants were diagnosed with developmental delay. Longitudinal trajectories of the incidence of brushes were different between the normal and the delayed development groups. Brushes were observed most frequently at 36 PMW in the delayed development group. The incidence of brushes at 36 PMW was significantly correlated with the severity of white matter abnormalities and negatively correlated with the developmental quotient.The incidence of brushes at 36 PMW can be a unique predictor of early neurodevelopment in extremely low birth weight infants without severe brain lesions.

Immunization is a fundamental component of preventive healthcare. This gain special significance in pregnancy. Maternal antigen-specific IgG, is actively transported across the placenta during pregnancy. This significantly, contributes to infant immunity in the first few months of life. Vaccination during pregnancy has the potential to indirectly protect the most vulnerable infants during the first few months of life, when vaccine responses are generally poor and it is difficult to achieve rapid protection through immunization. This is especially relevant when there is prior exposure to infection in woman or vaccine administration. A vaccine given during pregnancy in these women would result in a booster response and a relatively high level of IgG protecting their children in initial few months of life. Passive antibody transfer from mother to fetus can protect fetuses from infection until their own immunization schedule is initiated. Lack of administration of appropriate vaccination to women during pregnancy lead to an increase in maternal and fetal morbidity and mortality from preventable infections like influenza, pertussis. Various preventable infections can lead to intensive care unit admission for mothers, preterm birth, and low birth weight babies. Recent covid pandemic has brought issue of vaccine use in pregnancy at forefront of all expectant mothers. Immunization with inactivated virus, bacterial vaccine and toxoids showed no evidence of adverse fetal effects. As a rule, live attenuated vaccines are not recommended in pregnancy. This paper gives snapshot of all vaccines, which can be used in pregnancy along with brief details regards various bacterial and viral infections , their common clinical features and effects on pregnancy outcome as well as fetus. This is will provide a useful guide for healthcare providers.

Objective Assisted reproductive technology (ART) treatments are commonly used to aid conception in subfertile couples. This study aimed to evaluate the risks of adverse maternal and offspring outcomes in singleton pregnancy conceived with different ART treatments and techniques. Evidence Review We searched MEDLINE, Embase, CENTRAL, and HTA until December 2020 for all systematic reviews evaluating adverse outcomes in pregnancies conceived with various ART techniques, autologous or donor gametes, and embryo development stages. We assessed review quality using the AMSTAR 2 tool risk ratio (RR) or odds ratio (OR) with 95% confidence intervals (CIs) from the top quality reviews for each of the outcomes of interest across the identified ART treatments and population subgroups. Results We included 24 systematic reviews, which mostly reported on observational studies. Compared with spontaneous conception, ART pregnancies had a higher risk of placenta previa (RR, 3.71; 95% CI, 2.67–5.16), antepartum hemorrhage (RR, 2.11; 95% CI, 1.86–2.38), preterm birth (PTB) (RR, 1.71; 95% CI, 1.59–1.83), very preterm birth (RR, 2.12; 95% CI, 1.73–2.59), small for gestational age (SGA) (RR, 1.35; 95% CI, 1.20–1.52), low birth weight (LBW) (RR, 1.61; 95% CI, 1.49–1.75), and very low birth weight (VLBW) (RR, 2.12; 95% CI, 1.84–2.43). Frozen vs. fresh embryo transfer was associated with a lower risk of PTB (RR, 0.90; 95% CI, 0.84–0.97), SGA (RR, 0.61; 95% CI, 0.56–0.67), LBW (RR, 0.72; 95% CI, 0.67–0.77), and VLBW (RR, 0.76; 95% CI, 0.69–0.82). Embryo transfer at blastocyst vs. cleavage showed a higher risk of PTB (RR, 1.10; 95% CI, 1.01–1.20) and large for gestational age (RR, 1.12; 95% CI, 1.03–1.21) with a lower risk of SGA (RR, 0.84; 95% CI, 0.76–0.92). Using donor vs. autologous oocytes increased the odds of PTB (OR, 1.57; 95% CI, 1.33–1.86), LBW (OR, 1.94; 95% CI, 1.10–3.41), and VLBW (OR, 1.37; 95% CI, 1.22–1.54) as well as maternal complications, including postpartum hemorrhage (OR, 1.96; 95% CI, 1.20–3.20), gestational diabetes (OR, 1.27; 95% CI, 1.03–1.56), hypertensive disorders of pregnancy (OR, 2.63; 95% CI, 2.17–3.18), and cesarean section (OR, 2.28; 95% CI, 2.14–2.42). Conclusions Assisted reproductive technology treatments are associated with increased risks of adverse maternal and offspring outcomes, especially with donor oocytes. The characteristics of ART treatment should be incorporated into prenatal care planning to mitigate those risks. PROSPERO Registration CRD42020182612, registered March 9, 2020.

Transthoracic echocardiography (TTE) is increasingly utilized for guiding transcatheter closure of patent ductus arteriosus (PDA) in extremely low birth weight (ELBW) infants. The objectives of this study were to compare PDA size measurements by TTE with angiographic measurements and to describe TTE techniques used in guiding transcatheter PDA closure (TCPC) in ELBW infants.One hundred twenty-five consecutive ELBW infants (gestational age 27 weeks, birth weight 1 kg) who underwent TCPC before 8 weeks of age under TTE guidance were included. Patent ductus arteriosus sizes were measured from the procedural TTE and angiograms retrospectively by blinded observers. The TTE PDA diameters at the aortic (ED1) and pulmonary end (ED2) were compared with the corresponding angiographic diameters (CD1 and CD2). The TTE PDA lengths, obtained by two techniques (EL1, a straight line between ED1 and ED2; and EL2, a curvilinear line along the PDA), were compared with the PDA length by angiography (CL). Transthoracic echocardiography was used to guide accurate device positioning within the PDA.The procedure weight was 600-1,460 g. The TTE and angiographic PDA diameters were comparable (mean ED1 vs CD1 = 4.5 ± 0.68 vs 4.4 ± 0.85 mm, P = .26; and mean ED2 vs CD2 = 3.1 ± 0.72 vs 3.2 ± 0.94 mm, P = .14). The angiographic length was underestimated by EL1 by 2.6 ± 1.6 mm (P .0001), while EL2 estimated it better (mean EL2 vs CL = 11.0 ± 1.83 vs 10.8 ± 2.15 mm; P = .40). Transcatheter PDA closure was successful in 100% of the cases using TTE guidance. There were no intraprocedural complications.Transthoracic echocardiography guidance during TCPC in ELBW infants eliminates the need for aortograms via femoral arterial access, preventing the complications associated with it. Transthoracic echocardiography PDA measurements are comparable to angiographic measurements, thereby assisting in appropriate device size selection.

Aim To evaluate the incidence of congenital malformations in children exposed prenatally to antiseizure medications (ASMs), to assess other perinatal and fetal complications, and to determine the potential predictors for these complications. Method A retrospective review of pregnancy outcomes of women with epilepsy. Patients were followed up at the King Faisal Specialist Hospital and Research Centre, Riyadh and Jeddah, Saudi Arabia, between Dec 1993 and Oct 2020. Results Of 162 pregnancies included, 10 (6.17%) congenital malformations were observed, 6.82% in ASM-exposed babies versus 3.33% in babies of epilepsy-untreated mothers (P = 0.69). The overall incidence of perinatal and fetal complications was 53%; most frequent were low birth weight (24%), preterm birth (19%), transfer to neonatal intensive care unit (18%) and abortion (8%). These complications were higher in the untreated group (66.67%) than in the ASM group (50%). The use of other non-antiseizure medications during pregnancy was the only factor that significantly increased the risk of complications. Conclusion Prenatal exposure to ASMs was associated with increased risk of congenital malformations. However, overall perinatal and fetal complications were higher in the untreated group than in the ASM group, which could be explained by maternal seizures. Therefore, taking ASMs to control epilepsy and prevent perinatal complications may outweigh the risks of teratogenicity.

Objective: To investigate whether the reduced reproductive rate among men born small for gestational age (SGA) or with low birth weight (LBW) is present after up to 44 years of follow-up. Design: Population-based register study. Setting: National registers in Sweden. Patient(s): All men born in Sweden between 1973 and 1993 (n = 1,045,167) followed up to 2018. Intervention(s): None. Main Outcome Measure(s): Registered fatherhood, infertility diagnoses, and fertility treatments obtained from registers up to 2018 Result(s): Men born SGA or with LBW have a lower chance of becoming fathers than men born with normal birth characteristics: hazard ratio (95% confidence interval) 0.91 (0.90-0.92) and 0.88 (0.86-0.90), respectively. The reduction in reproductive rate is more evident after a longer follow-up time. Men born SGA were more likely to receive a diagnosis of infertility. Sperm donation and intracytoplasmic sperm injection were more often used in men born SGA, further strengthening the hypothesis of an association between birth characteristics and male infertility. Conclusion(s): Men born SGA or with LBW have a lower chance of becoming fathers, but the reduction in fertility is smaller for the younger cohort. Further studies are needed to determine if this difference is maintained. (C) 2021 by American Society for Reproductive Medicine. Funding Agencies|ALF grants, Region Ostergotland

Although most studies show that adolescent pregnant women are at a higher risk for adverse birth outcomes, there has been limited research examining this relationship in Canada. This systematic review and meta-analysis investigated the prevalence of low birthweight (LBW), preterm birth (PTB), and stillbirth in Canadian adolescent women compared to adult women. Studies were included if they were primary research and included a sample of adolescent mothers (≤19 years) and adult mothers (≥20 years) who gave birth to singleton infants in Canada. Birth outcomes must have been measured consistently in at least 3 studies for inclusion. Comprehensive electronic literature searches were conducted from database inception until August 2020 in 5 databases. Random effects meta-analysis models were used to estimate pooled odds ratios (pOR) for LBW, PTB, and stillbirth between adolescent and adult pregnant women. Outcomes reported included PTB (8 studies), LBW (6 studies), and stillbirth (3 studies). Compared to adult mothers, adolescent mothers had a 56% increase in the prevalence of LBW (pOR 1.56, 95% confidence interval [CI] 1.24, 1.97), a 23% increase in PTB (pOR 1.23, 95% CI 1.06, 1.42), a 20% increase in stillbirth (pOR 1.20, 95% CI 1.05, 1.37). Heterogeneity, as assessed by I2, was high for LBW and PTB and was low for stillbirth. A subgroup analysis did not remove the high heterogeneity, and some studies did not adjust for confounding variables and were missing information on sociodemographic and behavioral factors. Future research is needed to investigate the mechanisms surrounding these differences by maternal age.

Increasing numbers of Low Birth Weight (LBW) cases at Depok Regional Hospital demonstrate the need for more effective intervention. This study aimed to assess the knowledge of Kangaroo Mother Care (KMC) among health workers and its implementation. The study used a survey to measure the difference in the knowledge before and after KMC training. A qualitative research was also conducted to assess its implementation. Data were collected through in-depth interviews and Focus Group Discussions. The health workers’ knowledge scores increased between pretest and posttest. Although not formally trained in KMC the in-patient staff had a relatively good knowledge. However, the management and health workers in the outpatient unit did not. There are many challenges to improve the implementation of the KMC program.

Background Adequate gestational weight gain (GWG) is essential for healthy fetal growth. However, in low- and middle-income countries, where malnutrition is prevalent, little information is available about GWG and how it might be modified by nutritional status and interventions. Objective We describe GWG and its associations with fetal growth and birth outcomes. We also examined the extent to which prepregnancy BMI, and preconception and early weight gain modify GWG, and its effects on fetal growth. Methods This was a secondary analysis of the Women First Trial, including 2331 women within the Democratic Republic of Congo (DRC), Guatemala, India, and Pakistan, evaluating weight gain from enrollment to ∼12 weeks of gestation and GWG velocity (kg/wk) between ∼12 and 32 weeks of gestation. Adequacy of GWG velocity was compared with 2009 Institute of Medicine recommendations, according to maternal BMI. Early weight gain (EWG), GWG velocity, and adequacy of GWG were related to birth outcomes using linear and Poisson models. Results GWG velocity (mean ± SD) varied by site: 0.22 ± 0.15 kg/wk in DRC, 0.30 ± 0.23 in Pakistan, 0.31 ± 0.14 in Guatemala, and 0.39 ± 0.13 in India, (P

Literature has shown that mothers whose babies are in neonatal intensive care units (NICUs) are at risk of experiencing postpartum depression (PPD). This study explored the relationship between PPD and perceived social support and its impact on maternal adaptation in mothers of new-borns hospitalized in NICUs. Participants were 252 mothers of infants in the NICU. An Individual Form, the Edinburgh PD Scale, the Postpartum Self Evaluation Questionnaire, and the Multidimensional Scale of Perceived Social Support were used for data collection. Mann Whitney U test and Pearson Correlation were used for data analysis. Breastfeeding difficulty, inadequate information on postpartum, psychological disease history, C/S, low birth weight, prematurity, and long hospital stay was found to be predictors of PPD and poor maternal adaptation. As perception of social support and maternal adaptation decreased, PPD symptoms increased. Health providers should detect PPD symptoms of these mothers and have them referred early for counselling.

Introduction Previous studies have revealed that individuals with low birth weight (LBW) have higher risk of chronic kidney disease (CKD) and that LBW and CKD cluster in families. This study investigates how familial factors affect the association between birth-related risk markers and risk of CKD. Methods The Medical Birth Registry (MBR) of Norway has registered all births in Norway since 1967. Sibling data were available through the Norwegian Population Registry. The Norwegian Patient Registry has registered diagnostic codes for all admissions and outpatient visits to Norwegian hospitals since 2008. Data from these registries were linked. Risk of CKD according to whether the individual himself or at least one of his siblings had LBW was analyzed using logistic regression statistics. Results Of 1,847,565 individuals, 3336 had been diagnosed with CKD. Compared with individuals without LBW and no siblings with LBW, individuals without LBW but who had a sibling with LBW had adjusted odds ratio (aOR) of 1.33 (1.19–1.49), those with LBW but no siblings with LBW had aOR of 1.74 (1.55–1.95), and those with LBW and a sibling with LBW had aOR of 1.77 (1.54–2.04) for CKD. Similar results were found for LBW for gestational age, but preterm birth revealed weaker associations. Conclusion Individuals who have a sibling with LBW have an increased risk of CKD later in life, and individuals who themselves have LBW have an even higher risk. Our findings suggest that there are familial contributions to the nephron endowment in utero hypothesis., Graphical abstract

Background Donor milk is the standard of care for hospitalized very low birth weight (VLBW) infants when mother's milk is unavailable; however, growth of donor milk-fed infants is frequently suboptimal. Variability in nutrient composition of donated milk complicates the production of a uniform pooled product and, subsequently, the provision of adequate nutrition to promote optimal growth and development of VLBW infants. We reasoned a machine learning approach to construct batches using characteristics of the milk donation might be an effective strategy in reducing the variability in donor milk product composition. Objective The objective of this study was to identify whether machine learning models can accurately predict donor milk macronutrient content. We focused on predicting fat and protein, given their well-established importance in VLBW infant growth outcomes. Methods Samples of donor milk, consisting of 272 individual donations and 61 pool samples, were collected from the Rogers Hixon Ontario Human Milk Bank and analyzed for macronutrient content. Four different machine learning models were constructed using independent variable groups associated with donations, donors, and donor-pumping practices. A baseline model was established using lactation stage and infant gestational status. Predictions were made for individual donations and resultant pools. Results Machine learning models predicted protein of individual donations and pools with a mean absolute error (MAE) of 0.16 g/dL and 0.10 g/dL, respectively. Individual donation and pooled fat predictions had an MAE of 0.91 g/dL and 0.42 g/dL, respectively. At both the individual donation and pool levels, protein predictions were significantly more accurate than baseline, whereas fat predictions were competitive with baseline. Conclusions Machine learning models can provide accurate predictions of macronutrient content in donor milk. The macronutrient content of pooled milk had a lower prediction error, reinforcing the value of pooling practices. Future research should examine how macronutrient content predictions can be used to facilitate milk bank pooling strategies.

Objective To measure the rates of adverse obstetric outcomes in spontaneous delivery in a population of young women with high uptake of the bivalent human papillomavirus (HPV) vaccine. Study Design This was a population-based ecological study with data from the Aberdeen Maternity and Neonatal Databank, UK. All women born between 1986–1996 with spontaneous singleton live birth at age 20–30 years were included for analysis. Exposure was defined according to maternal year of birth and HPV immunisation eligibility: pre-immunisation cohort (1986–1990), catch-up immunisation cohort (1991–1994) and routine immunisation cohort (1995–1996). Outcomes were defined as spontaneous preterm birth (PTB), low birth weight (LBW) and pre-labour preterm rupture of membranes (pPROM). Generalized estimating equation models were applied, adjusted for deprivation, smoking status, marital status, body mass index, parity, maternal age and year of infant delivery. Results A total of 6515 spontaneous singleton live births were included in final analysis, with 5134 births included in the pre-immunisation cohort, 1250 in the catch-up immunisation cohort and 131 in the routine immunisation cohort. Compared with the pre-immunisation cohort, no statistically significant reduction on PTB, LBW or pPROM were observed in either immunised cohorts. The adjusted odds ratio (aOR) on PTB was 0.64 (95 % confidence interval, 0.40–1.03) in the catch-up cohort and 0.71 (0.28–1.77) in the routine cohort. The corresponding aOR were 0.88 (0.54–1.45) and 0.51 (0.16–1.62) for LBW and 1.62 (0.58–4.54) and 1.51 (0.21–11.01) for pPROM. Conclusions We did not observe a significant reduction on PTB, LBW or pPROM among spontaneous singleton live birth in either HPV immunised cohorts, although the additional benefit in improving obstetric outcomes cannot be excluded because of the limits of the sample size and the study design. Further demonstration is warranted when more women in the fully HPV immunised cohorts embark on pregnancy.

Antenatal depression has been associated with poor perinatal outcomes such as preterm birth and low birth weight. Universal screening of perinatal depression has been recommended to improve maternal and pregnancy outcomes.We hypothesise that screening for antenatal depressive symptoms may reduce the risk of preterm birth and low birth weight. To assess the hypothesis, we explore the association between antenatal depression screening using the Edinburgh Postnatal Depression Scale and neonatal outcomes.A retrospective analysis of state-wide population-based health administrative data. Inclusion criteria were pregnant women who gave birth to a singleton in Queensland in the second half of 2015 (29,543 women). Logistic regression analyses were run in 27,817 women with information in all variables. Main outcomes were preterm birth (37 weeks of gestation) and low birth weight (2500 grs).Women who did not complete the screening had increased odds of preterm birth (AOR, 1.56; 95% CI, 1.39-1.74; p 0.001) and low birth weight (AOR, 1.48; 95% CI, 1.30-1.68; p 0.001) before and after adjustments for relevant confounders when compared to women who completed the screening. Sensitivity analyses performed in women with spontaneous labour and in women without a diagnosis of depression showed similar results.We found an association between screening for depressive symptoms during pregnancy and better neonatal outcomes. However, this result does not necessarily infer causality. Any association may represent a previously unknown benefit to screening, which could support the case for universal antenatal depression screening.

Purpose : We aimed to investigate potential predictors of focal intestinal perforation (FIP) in extremely low birth weight infants (ELBWIs) among coagulation and fibrinolysis markers at birth. Methods : We reviewed the medical records of FIP patients and their coagulation and fibrinolysis markers at birth between 2010 and 2019, and matched patients according to gestational age. FIP was diagnosed based on macroscopic intestinal perforation with a punched-out lesion without necrosis. Patient characteristics and blood test results, including coagulation and fibrinolysis marker levels, were compared between the groups. Results : Two hundred forty ELBWIs were enrolled in this study (FIP, n = 18; controls, n = 222). In the FIP group, the gestational age at birth was significantly younger (p = 0.023) and the birth weight was significantly lower (p = 0.007) in comparison to the control group. Furthermore, the FIP group showed significantly lower levels of fibrinogen (p = 0.027) and factor XIII (F-XIII) (p = 0.007). The receiver operating characteristics curves for fibrinogen and F-XIII revealed that the 95% confidence intervals of fibrinogen and F-XIII were 0.530–0.783 (p = 0.027), and 0.574–0.822 (p = 0.007), respectively. Conclusions : This is the first report focusing on coagulation and fibrinolysis markers in FIP patients at birth. The fibrinogen and F-XIII values at birth are potential predictors of FIP in ELBWIs. Type of Study : Study of Diagnostic Test (Case Control Study) Level of Evidence : Level IV

Truncus arteriosus is a congenital heart defect with high resource use, cost, and mortality. Value assessment (outcome relative to cost) can improve quality of care and decrease cost. This study hypothesized that truncus arteriosus repair at a high-volume center would result in better outcomes at lower cost (higher value) compared with a low-volume center.This study retrospectively analyzed a multicenter cohort of neonates undergoing truncus arteriosus repair (2004 to 2015) by using the Pediatric Health Information Systems database. Multivariate quantile, logistic, and negative binomial regression models were used to evaluate total hospital cost, in-hospital mortality, ventilation days, intensive care unit length of stay (LOS), hospital LOS, and days of inotropic agent use by center volume (high-volume3/year) and age at repair while adjusting for sex, ethnicity, race, genetic abnormality, prematurity, low birth weight, concurrent interrupted arch repair, and truncal valve repair.Of 1024 neonates with truncus arteriosus, 495 (48%) were treated at high-volume centers. Costs at the 75th percentile were lower at high-volume vs low-volume centers by $28,456 (P = .02) at all ages at repair. Patients at high-volume centers had lower median postoperative ventilation days (5 days vs 6 days; P.001), intensive care unit LOS (13 days vs 19 days; P.001), hospital LOS (23 days vs 28 days; P = .02), and inotropic agent use (3 days vs 4 days; P = .004). In-hospital mortality did not differ by center volume.In neonates undergoing truncus arteriosus repair, costs are lower and outcomes are better at high-volume centers, thus resulting in higher value at all ages of repair. Value-based interventions should be considered to improve outcomes and decrease cost in truncus arteriosus care.

Objective To evaluate published literature on the associations between perinatal substance use (PSU), perinatal depression and anxiety (PDA), and known maternal–newborn outcomes. Data Sources We conducted a systematic search of health-related databases, including PubMed, CINAHL, MEDLINE, and Embase. Search terms included maternal mental health, substance use, postpartum, opioid, alcohol, methamphetamine, addiction, dependence, pregnancy, depression, and anxiety. Study Selection We included English-language, peer-reviewed reports of primary research and systematic reviews that were published between 2010 and 2020 and focused on PSU and PDA. We excluded commentaries, nonsystematic reviews, and articles on maternal mental health other than PDA. Fourteen of 379 articles met the inclusion criteria. Data Extraction We used the Joanna Briggs Institute Review Guidelines to guide extraction of the following data: author(s), year of publication, type of study, country of origin, study sample, targeted substance(s), mental health, key findings, and recommendation(s). Data Synthesis In studies of PSU, researchers identified a strong association with PDA. Likewise, researchers investigating PDA found a strong association with PSU. Findings from these articles suggest an increasing risk for PSU with increasing severity of PDA, depending on the specific substances of use. Findings also indicated that women with polysubstance use have greater odds for comorbid perinatal mental health conditions. A relationship between PSU and PDA and adverse newborn outcomes, such as low birth weight, was found. Conclusion There is a paucity of published research on co-occurring PSU and PDA. However, polysubstance use appears to be associated with the greatest risk for PDA. It is essential to address PSU and PDA together to better understand the effects on maternal and infant outcomes.

The aim was to systematically review and meta-analyze prospective cohort studies investigating the relation between maternal dietary patterns during pregnancy with pregnancy and birth outcomes. PubMed, Scopus, and ISI Web of Science were searched from inception until October 2019 for eligible studies. Studies reporting relative risk, ORs, or incidences (for binary data) or means ± SDs or B-coefficients (for continuous outcomes) comparing the highest and lowest adherence with maternal dietary patterns were included. Dietary patterns were categorized as “healthy,” “unhealthy,” or “mixed.” No language restrictions were applied. Study-specific effect sizes with SEs for outcomes of interest were pooled using a random-effects model. Quality of evidence was assessed using Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Sixty-six relevant publications were included. A higher maternal adherence to a healthy diet was associated with a reduced risk of gestational hypertension (14%, P

Summary Background Postnatal growth failure is common in very preterm infants and is associated with worse neurodevelopmental outcome. Objective To evaluate the cumulative impact of multiple evidence based strategies on the postnatal growth of extremely-low-birth-weight (ELBW) infants. Methods We conducted a prospective observational study. Based on current literature, changes were implemented to provide optimal parenteral and enteral nutrition. Daily intakes of calories, protein, lipids and carbohydrates were calculated. The average growth velocity (GV) was calculated using 2-point exponential model and is reported as grams/kg/day. The length and head circumference gains are reported as centimeters/week. Results The mean gestational age and birth weight for 38 ELBW survivors were 27.0 ± 2.1 weeks and 752 ± 147 g respectively. The GV was 13.2 ± 2.2 g/kg/day (range 8.8–17.4) and gains in length and head circumference were 0.88 ± 0.9 (range 0.15–1.42) and 0.71 ± 0.5 (range 0.22–0.96) centimeters/week respectively. Twenty nine (76.3%) infants were small-for-gestational-age (SGA) at discharge and 23 of these (60.5% of all infants) had weight below 3rd percentile. All 11 infants who were SGA at birth were SGA at discharge as well. Of 25 appropriate-for-gestational-age (AGA) infants at birth, 16 (64%) were SGA at discharge. The number of infants with length and head circumference below 10th percentile at birth and discharge were 11 (28.9%) and 29 (76.3%) for length and 20 (52.6%) and 27 (71.1%) for head circumference. Infants with multiple morbidities and more hospital days with no enteral feeds had lower GV. Conclusion All infants born SGA at birth and majority of ELBW survivors born AGA at birth had weight, length and head circumference below 10th percentile at discharge despite aggressive nutrition supplementation.

Background Low birth weight (LBW) in infants is a critical issue worldwide. If the issue is not recognized early, it can lead to high mortality and morbidity rates. Mothers and caregivers of LBW newborns holds a great responsibility and need appropriate information and expertise in caring for the LBW newborns. This study aimed to evaluate the effectiveness of a Nurse led structured teaching program (NLSTP) on the knowledge and practice of mothers of LBW infants. Methods A quantitative pre-experimental one group pre-test post-test research study was conducted. A sample of 30 postnatal mothers of LBW babies meeting the inclusion criteria were selected. The knowledge and practices of postnatal mothers on the care of LBW babies was tested using a structured interview schedule and a checklist before the administration of NLSTP. Thereafter, the NLSTP was conducted using an educational booklet. After the NLSTP, the knowledge and practice were assessed on the 7th day. Results The findings of the study reflected poor knowledge and practice scores before the intervention in the pre-test. However, the mothers gained a good level of knowledge showing marked improvement in their practices after the NLSTP was implemented. The mean post-test knowledge score (17.6) was significantly higher than the mean pre-test knowledge score (10.8) with a SD of +1.33. Likewise, the mean post-test practice score (15.6) was significantly higher than the mean pre-test practice score (8.23) with a SD of +7.5. The paired ‘t’ test computed between pre-test and post-test knowledge scores (t = 67.6) and practice scores (t = 5.28) were highly significant at p ≤ 0.05 level. A significant association was found between the pre-test knowledge scores and monthly family income (p Conclusion This study highlights that post-natal mothers have a lack of expertise in caring for their LBW babies. The NLSTP targeted at improving the knowledge and practices of post-natal mothers regarding the care of their LBW babies can help reduce the morbidity and mortality rates of LBW babies.

Objective To investigate the association of endometrium preparation with perinatal outcomes. Design Retrospective cohort study. Setting University-affiliated fertility center. Patient(s) Twenty-one thousand six hundred and forty-eight women who underwent frozen single-blastocyst transfer from January 2013 to March 2019. Intervention(s) None. Main Outcome Measure(s) Cesarean delivery, preterm delivery (PTD), vaginal PTD, very preterm delivery (VPTD), postterm delivery, low birth weight (LBW), macrosomia, small for gestational age (SGA), large for gestational age (LGA), hypertensive disorders of pregnancy (HDP), gestational diabetes mellitus (GDM), premature rupture of membrane (PROM), placenta previa, and congenital abnormality. Result(s) Compared with natural cycles, hormone replacement cycles were associated with an increased risk of PTD, VPTD, cesarean delivery, macrosomia, PROM, and HDP. There was a trend toward an increased risk of vaginal PTD and LGA in hormone replacement cycles. Stimulated cycles were associated with an increased risk of postterm delivery and GDM. There was no statistically significant difference in the rate of SGA, placenta previa, or congenital abnormality among the three endometrium preparation methods. Conclusion(s) Hormone replacement cycles are associated with an increased risk of PTD, VPTD, cesarean delivery, LBW, macrosomia, PROM, and HDP. Stimulated cycles are associated with an increased risk of postterm delivery and GDM.

Purpose This study examines the association between race and ethnicity, participation in The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), and a series of infant health outcomes including infant mortality, low birth weight, preterm birth, extended infant hospitalization, and stays in the neonatal infant care unit (NICU). Methods Data are from the Pregnancy Risk Assessment Monitoring System (PRAMS), 2009–2017. Moderation analyses were conducted to assess the association between maternal race and ethnicity, WIC participation, and infant health. Results Results indicate infants born to Black women and to a lesser extent Hispanic woman are in worse health than those born to White mothers in the United States. However, participation in WIC is associated with reductions in the gap in infant health experienced by racial and ethnic minorities. Conclusions Prenatal WIC participation is associated with improvements in the health of Black and Hispanic infants and reduced racial and ethnic disparities in infant health outcomes.

An assessment of the clinical data and outcome of patients with oesophageal atresia (OA) with very low birth weight (VLBW) was completed.With ethical consent, we reviewed the records of 327 successive patients with OA from 1980 to 2020. Main outcome measures survival and oesophageal repair were compared between patients with VLBW(≤1500 g) and with BW1500 g.Thirty-four (10%) patients had VLBW. Gross types of OA in VLBW were similar as in other patients: A (15%/7%), B (3%/3%), C (78%/82%), D (3%/4%), E (0%/7%), F (0%/1%) (p = 0.16-0.99). In VLBW the incidence of congenital heart disease (CHD) (47%) and trisomy 13/18 and Cri du Chat (15%) were higher than in BW1500 g (23% and 1%), (p = 0.001 both). In VLBW one-month mortality was 35% vs 4% in patients with BW1500 g (p 0.001), overall mortality 56% and 8% (p 0.001), respectively. Cause of one-month mortality in VLBW (12 patients) were CHD w/wo chromosomal abnormality (n = 7), cerebral hemorrhage (n = 2), gastric perforation (n = 1), anastomotic leakage (n = 1) and pulmonary hemorrhage (n = 1). Of VLBW patients 79% and of other patients 99% underwent oesophageal repair (p 0.001). Repair in VLBW patients included early (n = 18) or delayed (n = 5) end-to-end anastomosis and reconstruction (n = 4). Anastomotic complications occurred in 24% of patients with VLBW and in 17% with BW1500 g, (p = 0.31). From 1980-2000 to 2001-2020 survival in VLBW changed from 11% to 81% (p = 0.002). During 2001 - 2020 all VLBW patients underwent repair.OA with VLBW had high incidence of life-threatening associated anomalies and decreased survival. Recently survival and rate of oesophageal repair have improved significantly.

The concept that origins of cardiovascular disease (CVD) begin in childhood is supported by substantial evidence. Prospective studies beginning in childhood report associations of childhood obesity, abnormal blood pressure (BP), dyslipidemia, diabetes, and tobacco use with intermediate CVD markers, including left ventricular hypertrophy and vascular stiffness in young adulthood. Trajectory analyses from longitudinal studies describe discrete BP pathways from childhood to young adult status of hypertension and prehypertension. Among individuals with familial hypercholesterolemia, abnormal low-density lipoprotein cholesterol levels are present in childhood. Some children are at risk for future CVD owing to hereditary factors, psychosocial stress, race, low birth weight, or other nonmodifiable exposures. Behavioural factors, including suboptimal diet, sedentary activity, and tobacco use, in childhood augment risk and can be modified to reduce risk. Pharmacologic treatments are reserved for those at high levels of the BP and cholesterol distributions and for those with diabetes and additional risk factors.

Background Spontaneous intestinal perforation (SIP) and necrotizing enterocolitis (NEC) are complications of extremely low birth weight (ELBW, ≤ 1000 g) infants. ELBW infants at Texas Children's Hospital receive an exclusive human milk-based diet, which has been associated with a reduction of NEC. Objectives 1) Assess incidence of SIP and NEC (Stage II or greater) in ELBW infants receiving 100% human milk-based diet, 2) Describe mortality rates of ELBW infants with SIP and NEC. Methods Prospective single-center observational cohort study of ELBW infants born between 2010 and 2014 with SIP or NEC (exclusion: congenital anomalies and death within 48 h). Results Of 379 ELBW infants, 345 were eligible. Of these, 28 (8.1%) had SIP and 8 (2.3%) had NEC (medical n = 1, surgical n = 7). SIP infant mortality was 32% (n = 9) compared to 63% (n = 5) for NEC patients. Of SIP infants with PD (n = 25), 52% required subsequent exploratory laparotomy (LAP). Of NEC infants with peritoneal drainage (PD) (n = 2), both required subsequent LAP. Conclusion Using an exclusive human milk-based diet, the incidence of SIP exceeds NEC in ELBW infants at our institution. This shows a changing trend in the incidence of these two diagnoses in the era of human milk, as NEC had previously been more prevalent in ELBW infants. More than half of infants who initially received PD later required LAP. There were no differences in survival outcomes in both SIP and NEC groups based on surgical management.

Background To determine if birth-weight (BW) influences primary surgical management of newborns undergoing operation for esophageal atresia and tracheo-esophageal fistula (EA-TEF). Methods Newborns undergoing repair of esophageal atresia at a single specialist centre between 1999 and 2017 were categorised into three groups based on BW; Group A 2.5 kg. Outcome data analysed were (i) technical ability of the surgeon to perform primary esophageal anastomosis, (ii) anastomotic leak, (iii) anastomotic stricture, (iv) esophageal replacement, (v) need for other procedures notably fundoplication, aortopexy, tracheostomy and (vi) mortality. Statistical analysis was performed using a two-tailed Fisher's exact test and logistic regression. Results 198 patients underwent surgery for EA-TEF during the study period, Group A (n = 13), Group B (n = 73) and Group C (n = 112). Inability to perform a primary anastomosis was significantly higher in Group A vs Group B (p = 0.003) and Group C (p = 0.004). Birthweight was a significant variable in the ability to perform a primary esophageal anastomosis (OR 1.009, p = 0.004). Mortality rate was significantly higher in Group A vs Group C (P = 0.0158). Conclusions Very low birth weight infants are less likely to achieve a definitive primary anastomosis during emergent repair of esophageal atresia, and have a higher mortality.

Background Stressful life events as important stressors have gradually been recognized as the potential etiology that may lead to adverse birth outcomes such as preterm birth (PTB), low birth weight (LBW), and small for gestational age (SGA). However, researches on this topic have shown relatively inconsistent results. This systematic review and meta-analysis was performed to synthesize available data on the association between prenatal stressful life events and increased risks of PTB, LBW, and SGA. Methods Electronic databases were searched from their inception until September 2020. Pooled relative risks (RRs) and 95% confidence intervals (CIs) were calculated to assess the association between prenatal stressful life events and PTB, LBW, and SGA using random effects models. In addition, subgroup analyses, cumulative meta-analyses, sensitivity analyses, and publication bias diagnosis were conducted. STATA 14.0 was applied for statistical analyses. Results Totally 31 cohort studies involving 5,665,998 pregnant women were included. Prenatal stressful life events were associated with a 20% higher risk of PTB (RR = 1.20, 95%CI = 1.10-1.32), a 23% increased risk for LBW (RR = 1.23, 95%CI = 1.10-1.39), and a 14% higher risk of SGA (RR = 1.14, 95%CI = 1.08-1.20). Sensitivity analysis indicated the results were stable. Conclusions Findings indicated that pregnant women experiencing prenatal stressful life events were at increased risk of PTB, LBW, and SGA. This information provided additional supports that pregnant women experiencing prenatal stressful life events would benefit from receiving assessment and management in prenatal care services.

Background: The role of intrauterine infection in the development of neonatal pulmonary disease is unclear and the impact of histological chorioamnionitis (HCAM) on respiratory outcomes in preterm infants remains controversial. The aim of this study was to explore the association between HCAM and neonatal respiratory outcomes in very-low-birth-weight (VLBW) preterm infants and evaluate the stepwise difference in the stage and severity of HCAM among neonatal respiratory outcomes. Methods: We retrospectively enrolled 129 VLBW preterm infants with placenta histopathology examinations in this study. HCAM was subdivided into 3 stages (early, intermediate, and advanced) according to the progression of the maternal inflammatory response. The perinatal characteristics, placental histopathology, and neonatal morbidities, including respiratory outcomes (respiratory distress syndrome (RDS), Wilson-Mikity syndrome (WMS) and bronchopulmonary dysplasia (BPD)), were collected for comparison. Results: A total of 52.7% (68/129) of the infants had HCAM, including 23 early (stage 1), 30 intermediate (stage 2), and 15 advanced (stage 3) stage. There was no significant difference in the gestational age, birth body weight or mortality rate between the HCAM and non-HCAM groups. Mothers with HCAM had a significantly lower incidence of pre-eclampsia but a higher rate of premature rupture of membrane. They also had higher WBC counts and C-reactive protein levels before delivery. Neonates with HCAM had a lower incidence of RDS but were at a higher risk for developing WMS and BPD. After multivariate analysis adjustment, HCAM was still negatively associated with RDS (aOR = .069, p

Background Low birth weight continues to be a significant public health problem globally. Kangaroo Mother Care (KMC) comprises of early and continuous skin-to-skin contact between mother and baby as well as exclusive breastfeeding. More interest has been given to initiate KMC at the health facility for low birth weight babies born at home but, there has been trace evidence to support initiation of KMC at home. Thus, this study was aimed to estimate the proportion of mothers who continued to practice kangaroo mother care at home and identify factors influencing this practice following hospital discharge. Methods It was a cross-sectional study of 190 mothers with their low birth weight babies who were discharged from KMC unit at Dessie referral and Akesta hospitals and counseled about KMC to practice at home. In the first week following hospital discharge, the data collectors visited the mothers to interview her about KMC practices and the factors influencing it and analyzed by SPSS V.25.0. Crude odds ratio and adjusted odds ratio were performed to test the association between dependent and independent variables. Result The proportion of mothers who practice KMC at home was 89(46.8%). Multivariate logistic regression showed that support from husband (AOR = 4.4, 95% CI = 1.8–10.4), support from health extension works(HEW)(AOR = 3.4, 95% CI = 1.6–7.2), availability of helper (AOR = 4.5, 95% CI = 1.9–4.10) and mothers explained the important of KMC (AOR = 2.3,95% CI = 1.1–4.9) were statistically associated with KMC practices at home. Conclusion This study concludes that support comes from husband, health extension workers and family. Understanding of mothers about the importance of KMC was found to be one of the significant enhancing factors to implement KMC at home.

Aim of the work To assess the outcome of planned pregnancies in patients with systemic lupus erythematosus (SLE). Patients and methods: The study was conducted on 32 patients. The medical management included pre-pregnancy planning at the quiescent phase of the disease and after at least six months of clinical remission. The patients had a monthly visit during pregnancy and three months post-delivery. Disease flare was characterized by the recurrence of symptoms and signs in different organs, as well as the need for an increase in medication dose. Results: There were 36 planned pregnancies in 32 patients, of which 15 and 17 cases were primiparous and multiparous, respectively. The SLE flares were observed in 36.1% of the cases, 8.3% of which developed postpartum; moreover, they were moderate in severity and mostly involved the kidneys and joints. Pregnancy outcomes included18 (50%) cases ended in term labor; 13 (36.1%) pregnancies had preterm labor, and 5 (13.8%) pregnancies terminated with abortions. Furthermore, obstetric complications included 2(6.5%) patients with premature rupture of membranes, 5(15.6%) fetuses with intrauterine growth retardation, and 2(6.4%) mothers with preeclampsia. 10(27.7%) pregnancies occurred in patients with lupus nephritis. Cesarean section was performed on 24(77.4%) patients, and low birth weight was observed in 7(21.8%) infants. None of the infants had neonatal lupus, congenital deformities or infection. Conclusion: Pre-pregnancy planning in patients with SLE can considerably improve pregnancy outcomes. Neonatal lupus, congenital anomalies or infection were not present. SLE patients intending to become pregnant should be provided with close medical supervision for a safe maternal and fetal outcome.

Syphilis remains a common congenital infection over the globe. There has been a tremendous rise in the number of congenital syphilis cases worldwide in the last 20 years. It affects large numbers of pregnant mothers in high burden regions causing a significantly high perinatal mortality and morbidity, which can be easily prevented by early antenatal screening and treatment. Diagnosis of maternal syphilis in pregnancy mainly based on clinical symptoms, serological tests and direct identification of treponemes in clinical samples. However, the diagnosis can be challenging due to the relapsing-remitting nature of the disease. The early stage of the infection is usually symptomatic which is commonly followed by an asymptomatic latent phase but infectious and as a result serological tests will be positive. The risk of transplacental transmission is high during the second and third trimester. Obstetric complications of syphilis include spontaneous miscarriage, non-immune hydrops, stillbirth, preterm labour, low birth weight, increased neonatal mortality and congenital syphilis among neonates. Penicillin is the drug of choice for treatment and should be commenced immediately. Babies born to mothers with syphilis should also be treated with penicillin. Early detection and prompt intervention are the key to the prevention and successful control of congenital syphilis. The aim of this review is to highlight the impact of syphilis infection on pregnancy and discuss the current trends in diagnosis and management of maternal and congenital syphilis.

Objective To compare obstetric and neonatal outcomes resulting from assisted reproductive technology in couples with a history of female sterilization to couples with other infertility diagnoses. Design Retrospective cohort study. Setting Not applicable. Patient(s) Fresh, nondonor cycles excluding gestational surrogacy from 2004 to 2013 in the United States. Intervention(s) None. Main Outcome Measure(s) Preterm birth rates and low birth weight rates from in vitro fertilization (IVF) pregnancies in couples with infertility and in couples with prior tubal ligation as their sole indication for IVF. Result(s) The mean ages of fertile women (N = 8,478) and infertile women (N = 371,488) were 35.3 and 34.6 years, respectively. Of the singletons born to parous women (N = 26,463), the incidence of preterm birth was not significantly different in fertile, sterilized couples compared to infertile couples (13.7% vs. 12.0%). The incidence of low birth weight among term singletons was also not significantly different between fertile couples compared to infertile couples (3.5% vs. 3.2%). Conclusion(s) Fertile couples have similar preterm birth and low birth weight rates after IVF compared to infertile couples. This suggests that differences in perinatal outcomes may be due to assisted reproductive technology procedures rather than infertility itself.

Purpose Preterm birth is associated with adverse pulmonary outcomes. We aimed to evaluate respiratory morbidities and lung function of very low birth weight (VLBW) Polish children followed up at the age of 7 years old, and to compare with electrical impedance segmentography (EIS) results recorded at 4 years of age. Materials and methods VLBW children were compared with term controls using impulse oscillometry and spirometry. Perinatal data and current respiratory morbidities were analyzed and pulmonary function test results were compared with previous EIS results. Results We included 40 VLBW children and 30 controls in the analysis. Elevated total airway resistance and forced expiratory volume in the first second below the lower limit of normal were more prevalent in VLBW children compared with term controls (15 vs 0%; 18 vs 0%). A positive bronchodilator response was more common in VLBW children (R5 Hz: 46 vs 13.3%; R5–20 ​Hz: 65 vs 36.7%). Children with bronchopulmonary dysplasia (BPD) had higher total airway resistance (R5 Hz/R5 Hz pred: 1.35 vs 0.95; p ​ Conclusion VLBW school-aged children with BPD presented with substantial respiratory morbidity and persistent reduction of lung function, affecting small and large airways and lung parenchyma. EIS may be an alternative tool for lung function assessment in children with BPD.

BACKGROUND Thrombosis in the neonatal population is rare, but increasing. Its incidence and management are not well understood. OBJECTIVES To investigate the incidence, associated factors, and management of thrombosis in the neonatal intensive care unit (NICU) population. PATIENTS/METHODS We performed a retrospective cohort study of infants admitted to a Pediatrix Medical Group-affiliated NICU from 1997 through 2015. We determined the prevalence of venous and arterial thrombosis, and assessed demographic characteristics and known risk factors. Categorical variables were compared with the Pearson χ2 test and continuous variables with Wilcoxon rank-sum tests. Stepwise logistic regression was used to identify associated factors. The primary outcome was incidence of thrombosis. Secondary analyses investigated correlations between clinical and demographic characteristics and thrombosis. RESULTS Among 1 158 755 infants, we identified 2367 (0.20%) diagnosed with thrombosis. In a multivariable regression analysis, prematurity, male sex, congenital heart disease, sepsis, ventilator support, vasopressor receipt, central venous catheter, invasive procedures, and receipt of erythropoietin were associated with increased risk of thrombosis, while Black race and Hispanic ethnicity were associated with reduced risk. The majority of infants diagnosed with thrombosis (73%) received no anticoagulation, but anticoagulant use in infants with thrombosis was higher than those without (27% versus 0.2%, P

Objective The delay of childbearing in women has become a worldwide issue in recent decades. The application of assisted reproductive technology in women of advanced maternal age (AMA) is increasing. Evidence on the safety and outcomes of frozen embryo transfer (FET) compared with fresh embryo transfer (ET) in AMA women is still lacking. Therefore, the objective of the present study was to compare perinatal and maternal outcomes after autologous FET and fresh ET cycles in women of AMA. Study design A retrospective study of 1663 FET and 3964 fresh ET cycles in reproductive medical centers from 2009 to 2014. Women who aged ≥35 years and had clinical pregnancies after autologous frozen or fresh ET were included. The main perinatal outcomes included birth weight, gestational age, rates of preterm birth, macrosomia, low birth weight (LBW), and very low birth weight. The main maternal outcomes included rates of hypertensive disorders of pregnancy, gestational diabetes mellitus, and preterm premature rupture of the membranes. Results Women who underwent FET had an increased risk of hypertensive disorders of pregnancy [1.1 % vs. 0.4 %, adjusted OR (95 % CI): 2.76 (1.39−5.51); p = 0.004]. Singletons born after FET had significantly higher mean birth weight (3388.78 ± 538.47 vs. 3316.19 ± 549.08; p = 0.001). Furthermore, increased risk of macrosomia [13.5 % vs. 10.4 %, adjusted OR (95 % CI): 1.35 (1.07−1.71); p = 0.013] and decreased risk of LBW [3.6 % vs. 5.3 %, adjusted OR (95 % CI): 0.67 (0.45−1.00); p = 0.048] were found in singletons born after FET. Conclusions Perinatal risks of AMA patients are higher in FET than in fresh ET, including higher birth weight, risks of macrosomia in singleton births, and hypertensive disorders of pregnancy.
