Abstract 4130622: Neonatal Outcomes of Hypertensive Women Across US Races: 2016-2022

Background: Maternal hypertension, a major pregnancy complication, can adversely affect newborn health. We aim to evaluate the racial and ethnic disparities in neonatal outcomes among hypertensive pregnant women in the United States. Methods: Using data from the CDC WONDER Natality database, we conducted a retrospective cohort study focusing on live births to hypertensive mothers from 2016 to 2022. Neonatal outcomes, including NICU admissions, low birth weight, infant mortality, and assisted ventilation, were analyzed by calculating rates [95% CIs] per 1000 live births across maternal racial/ethnic groups and the US Census Bureau's regional classification: Northeast, Midwest, South, and West. Results: We analyzed 2,336,679 live births to hypertensive women (23% pre-pregnancy; 77% gestational). This cohort comprised: 0.2% infants born to Native Hawaiian/other Pacific Islander women (NH/PI), 0.9% to American Indian/Alaska Native women (AI/AN), 3.8% to Asian American women (AA), 19.6% to Hispanic/Latino women (H/L), 20.0% to Black/African American women (BA), and 55.4% to White American women (WA). Infant mortality rates were highest in BA (3.6 [3.5, 3.8]), followed by AA (2.1 [1.8, 2.4]), AI/AN (2.1 [1.6, 2.7]), H/L (1.9 [1.8, 2.0]), NH/PI (1.9 [1.0, 3.3]), and lowest in WA (1.5 [1.4, 1.6]). Similarly, NICU admission rates were highest in BA (217.2 [216.1, 218.4]) and lowest in WA (156 [155.4, 156.6]). Assisted ventilation rates were highest in NH/PI (131.8 [123.4, 140.7]) and lowest in AA (87.8 [86.0, 89.7]). Low birth weight rates were highest in BA (235.1 [233.9, 236.3]) and lowest in WA (121.8 [121.2, 122.4]). The Midwest had the highest rates for NICU admissions in NH/PI (254.2 [217.2, 295.2]), assisted ventilation in AI/AN (143.8 [133.2, 155.1]), and mortality in BA (4.1 [3.7, 4.5]). The South had the highest rate of low birth weight for BA (244.4 [242.9, 246.0]). Conclusion: Significant racial and regional disparities exist in neonatal outcomes among hypertensive women in the US. BA mothers consistently experienced the poorest outcomes, while WA mothers had the best. Further research is crucial to understand the reasons behind these disparities and develop targeted interventions for high-risk populations.

Adverse maternal outcomes and associated factors among mothers of advanced age delivering at a tertiary hospital, southwestern Uganda: a cross-sectional study

BackgroundMothers of advanced age, defined as pregnant women aged ≥ 35 years at the time of giving birth, are traditionally known to be associated with increased risks of adverse maternal outcomes. We determined the prevalence of adverse maternal outcomes and associated factors among mothers of advanced age who delivered at Kabale Regional Referral Hospital (KRRH), in Southwestern Uganda.MethodsWe conducted a cross-sectional study at the Maternity Ward of KRRH from April to September 2023. We consecutively enrolled pregnant women aged ≥ 35 years during their immediate post-delivery period and before discharge. We obtained data on their socio-demographic, obstetric, medical characteristics and their maternal outcomes using interviewer-administered questionnaires. We defined adverse maternal outcome as any complication sustained by the mother that was related to pregnancy, delivery and immediate post-partum events (obstructed labour, antepartum haemorrhage, mode of delivery [cesarean or vacuum extraction], postpartum haemorrhage, hypertensive disorders of pregnancy, preterm or postdate pregnancy, anemia, premature rupture of membranes, multiple pregnancy, and maternal death). A participant was considered to have an adverse outcome if they experienced any one of these complications. We identified factors associated with adverse outcomes using modified Poisson regression.ResultsOut of 417 participants, most were aged 35–37 years (n = 206; 49.4%), and had parity ≥ 5 (65.5%). The prevalence of adverse maternal outcomes was 37.6% (n = 157, 95%CI: 33.1–42.4%). Common adverse maternal outcomes included caesarian delivery (23%), and obstructed labour (14.4%). Other complications included anemia in pregnancy (4.5%), chorioamnionitis (4.1%), preterm prelabour rupture of membranes (3.9%), and chronic hypertension and preeclampsia (both 2.4%). Factors associated with adverse maternal outcomes were precipitate labour (adjusted prevalence ratio [aPR] = 1.95, 95%CI: 1.44–2.65), prolonged labour, lasting > 12 h (aPR = 2.86, 95%CI: 1.48–3.16), and chronic hypertension (aPR = 2.01, 95%CI: 1.34–3.9).ConclusionApproximately two-fifth of the advanced-aged mothers surveyed had adverse outcomes. Mothers with prolonged labour, precipitate labour and chronic hypertension were more likely to experience adverse outcomes. We recommend implementation of targeted interventions, emphasizing proper management of labor as well as close monitoring of hypertensive mothers, and those with precipitate or prolonged labor, to mitigate risks of adverse outcomes within this study population.

Association of preeclampsia, placental pathology, and maternal-fetal features with gestational hypertension before and after 34 weeks of pregnancy

Objective: Evaluating the preeclampsia, placental pathology, maternal and fetal features in women with gestational hypertension (GH) at varying gestational ages. Methods: A series of maternal, fetal, placental pathological, and neonatal variables were prospectively evaluated and compared between two 30-tuple groups of eligible pregnant women with early GH before 34 weeks' gestation and those with late GH after 34 weeks' gestation. Results: Proteinuria and preeclampsia were more prevalent in the early GH group compared with the late GH group (80% vs 20%, P:0.001). The maternal high blood pressure and proteinuria were significantly associated with the early GH and preeclampsia (p<0.05). The percentage of syncytial knots significantly increased as preeclampsia progressed (P<0.05). A significant positive correlation existed between the early GH and the percentage of newborns admitted to NICU, the length of hospitalization, and the levels of the doppler indexes of umbilical and uterine arteries (p<0.05); the newborn Apgar scores were also lower in the early GH group (p<0.05). The mortality rate of newborns born to early hypertensive mothers (13.30%) was insignificantly higher than those delivered by the late hypertensive mothers (3.30%, p:0.16). Conclusion: Maternal high blood pressure and proteinuria may be predicting risk factors for the early GH and/or preeclampsia. The placentas of women with early GH were partially different from those with GH after 34 weeks' gestation. Higher rates of maternal and fetal pregnancy-related complications in the early GH group may be indicative of the different effects of GH and preeclampsia on pregnancy outcomes depending on the gestational age.

CHILD BLOOD PRESSURE AND RENAL FUNCTION DIFFERENCES BY SUBTYPES OF MATERNAL HYPERTENSIVE DISORDERS OF PREGNANCY

Objective: The objective of this study is to investigate the difference child blood pressure (BP) and renal function by subtypes of maternal hypertensive disorders of pregnancy (HDP). Design and method: The Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study is a prospective birth cohort study including pregnant women, children and their families. Using available data of children at 8 years old from December 2022 to March 2023, we analyzed the association between maternal HDP subtypes by extracted from medical record and systolic and diastolic BPs and estimated glomerular filtration rate (eGFR) collected at research facilities. Analysis of covariance adjusted for their sex, body mass index, small for gestational age were performed. Maternal grandparental hypertension and paternal hypertension for child BP, and maternal grandparental chronic nephritis and parental chronic nephritis were additionally adjusted. Results: A total of 684 children (357 male and 327 female) at 8 years old was included in this study. Among them, 56 children had mothers with HDP (24 gestational hypertension, 11 preeclampsia, 9 superimposed preeclampsia, 12 chronic hypertension). The mean (standard deviation) systolic/diastolic BPs and eGFR were 106.90 (10.51)/64.68 (8.77) mmHg and 110.91 (16.23) mL/min/1.73m2, respectively. Estimated systolic/diastolic BPs (standard error) of children with normotensive mothers, those with gestational hypertension mothers, those with preeclampsia mothers, those with superimposed preeclampsia mothers, and those with chronic hypertension mothers were: 106.44 (0.76)/64.58 (0.64) mmHg, 108.38 (2.11)/64.80 (1.78) mmHg, 107.59 (3.10)/64.70 (2.61) mmHg, 108.38 (3.38)/63.64 (2.85) mmHg, 112.19 (2.98)/64.58 (2.51) mmHg, respectively. Upon classification of HDP subtypes, estimated eGFR were as follows: 110.11 (1.23) mL/min/1.73m2, 111.61 (3.40) mL/min/1.73m2, 118.20 (4.99) mL/min/1.73m2, 105.13 (5.43) mL/min/1.73m2, and 119.42 (4.82) mL/min/1.73m2, respectively. The p-values were above 0.05 for the systolic and diastolic BPs and eGFR among HDP subtypes. Conclusions: The follow-up measurement is ongoing until 2026; therefore, further study with updated dataset is necessary and will be provided.

Usefulness of Umbilical Cord Nucleated RBC as a Prognostic Marker of Neonate Born to Pregnancy Induced Hypertension Mother in Resource Limiting Settings

Background: Pregnancy induced hypertension are multi-system disorders of the mother that affect the fetusbecause of utero-placental insufficiency. These neonates may also have a spectrum of hematological changes which may add to the existing morbidity in them. objectives: To correlate cord Nucleated red blood cells and neonatal outcome in Pregnancy induced hypertension.Materials and method: The study was conducted in the Mata Chanan Devi Hospital, Janakpuri, New Delhi. A total of 55 cases and 55 controls of newborns fulfilling the inclusion criteria. The mother’s antenatal records were examined to rule out the Pre-Existing maternal medical illness. History of drug intake and complianceof treatment was recorded. Results: Cord blood nucleated red blood cells was significantly raised inneonates born to PIH mothers (>13 NRBC/100 WBC) compared to normotensive mothers and also hadsignificantly higher incidence of Low birth weight, Hypoglycemia, Respiratory distress and Asphyxia.Conclusion: NRBC count can be used as a simple tool where expertise not available and accordingly can plan the interventions. It is a special boon in a rural care center, where advanced diagnostic modalities are unaffordable or inaccessible. Umbilical cord NRBC count it correlates well with neonatal outcome.

Morphological Variations of the Umbilical Cord of Full-term Fetuses – Correlation with Maternal and Newborn Parameters

Introduction: Abnormalities in the development and site of insertion of the umbilical cord (UC) can cause problems which have the potential to affect maternal and fetal health. The aim of the present study was to evaluate the gross features of UC of singleton pregnancies and correlate it to the newborn parameters and maternal parameters at term. Materials and Methods: An observational, descriptive pilot study was carried out with 100 placentas. All ethical principles for human research were followed and ethical approval was obtained from the institutional ethics committee of the medical college from where data were collected. The inclusion criteria were the adequately preserved placenta with no gross abnormalities. Placenta belonging to hypertensive mothers and mothers with gestational diabetes were excluded. Results and Conclusion: The UC morphology was recorded and analyzed. Newborn parameters and maternal parameters were correlated to UC parameters. The present study statistics showed 53% placentas with central insertion, 36% eccentric insertion, 3% furcated and marginal insertions each, and 5% specimens with velamentous insertion. A correlation between the UC insertion site and birth weight was observed. Low birth weight was observed when the cord was inserted eccentrically. Further investigations are required among velamentous insertion to reach a conclusion for maternal blood group correlations.

Comparative study on ultrasonic placental grading among normotensive pregnancy and pregnancy-induced hypertension and its correlation with fetal outcome

Background: Placenta is essential for the fetal well-being, growth, and development which can be evidenced as early as possible through ultrasound at 6 weeks of gestation. The placenta mediates the intrauterine interaction between a mother and her baby. Aims and Objectives: This study aims to compare the pattern of placental grading among normotensive and pre-eclampsia mothers in a tertiary care hospital. Materials and Methods: This hospital-based observational analytical study has been conducted in the labor ward and outpatient department of the Department of Obstetrics and Gynaecology, Bankura Sammilani Medical College and Hospital from April 2021 to September 2022. A total of 69 pre-eclampsia mothers (study group) and 69 normotensive mothers (control group) who fulfill inclusion and exclusion criteria were included in the study. Template was generated and analysis was done on Statistical Package for the Social Sciences software. Results: A total of 138 pregnant women with 69 pregnant normotensive and 69 pregnant preeclampsia mothers were included in the study. The mean age of the study participants was 21.3 years (standard deviation=3.6). About 81.2% and 89.9% of the normotensive and hypertensive mothers, respectively, resided in rural areas. Cesarean/instrumental delivery was higher among the hypertensive pregnant women (42.0%) when compared to normotensive pregnant women (27.5%) and it was found to be statistically significant. Birth asphyxia was observed to be higher among the neonates in the hypertensive group (15.9%) when compared to the normotensive group (4.3%) and it was found to be statistically significant. Neonatal intensive care unit admission was more among the neonates of the mother with hypertension and it was found to be statistically significant. There was no significant difference in the birth weight of the newborn with the placental grading among the normotensive pregnant women. Conclusion: Ultrasonographic placental grading could be used as a screening tool for antepartum fetal surveillance in the obstetric population. Placental grading will help us to early diagnosis and to formulate line of management and timely intervention to reduce maternal and perinatal complications.

Sympathetic Neurofunction Testing in Gestational Hypertension and Relationship with Developing Preeclampsia and Eclampsia: Real-world Evidences from Clinical Pharmacology Clinics.

Gestational hypertension carries a high-risk for adverse maternal and fetal outcomes, and it can also develop into preeclampsia. A relative decrease in parasympathetic and increase in sympathetic activity has been seen in normal pregnancy which returns to baseline after delivery. The present study aimed to detect any abnormality in sympathetic neurofunction in gestational hypertension and to identify its possible association with the development of preeclampsia/eclampsia. A prospective, observational study was carried out among gestational hypertensive patients between 24 and 26 weeks of gestation, who were sent to clinical pharmacology clinics for autonomic neurofunction testing, along with their 24-hour urinary protein testing reports. Preisometric handgrip (IHG) and post-IHG differences in diastolic blood pressure (DBP) were noted. The association between Δ DBP and the development of eclampsia/preeclampsia was probed. A total of 52 pregnancy-induced hypertension (PIH) participants, both multigravida (n = 15) and primigravida (n = 37) were included in one arm (PIH arm), and 52 matched (age and gravida) pregnant women, those do not have PIH included in another arm for comparative analysis. On comparing the PIH arm and normal arm, prehand grip DBP (p ≤ 0.0001), posthand grip DBP, and Δ DBP were significantly higher in the PIH arm. Correlation between Δ DBP and 24 hours' proteinuria was observed in the PIH arm, with a significant positive correlation. A high-rise in DBP post-IHG exercise is associated with gestational hypertensive mothers and this rise is strongly correlated with the development of preeclampsia and eclampsia, which suggests that addressing sympathetic hyperactivity could be a potential area to target therapeutics while managing gestational hypertension.

Prevalence, trend, and associated risk factors for cleft lip with/without cleft palate: a national study on live births from 2016 to 2021

BackgroundsCleft lip with or without cleft palate (CL/P) is the most common congenital craniofacial anomaly, including non-syndromic cleft lip with or without cleft palate and cleft palate only. Failure in the fusion of median and lateral nasal processes, the maxillary prominence, and soft tissues around the oral cavity can cause CL/P. Previously, the prevalence has been estimated to be 1 among every 1000 births in 2014 among American neonates and no other reports have been available since. Thus, this study aimed to calculate the prevalence and trend of isolated CL/P among American live births from 2016 to 2021 with its associated risk factors.Methods and materialsIn this cross-sectional population-based retrospective study, we used live birth data provided by the National Center for Health Statistics (NCHS) from the Center for Disease Control and Prevention (CDC). We calculated the prevalence per 10,000 live births of isolated (non-syndromic) CL/P from 2016 to 2021. To examine risk factors for developing isolated CL/P, we used logistic regression modelling.ResultsThe total prevalence per 10,000 births from 2016 to 2021 was 4.88 (4.79–4.97), for both sexes, and 5.96 (5.82–6.10) for males, and 3.75 (3.64–3.87) for females. The prevalence did not show any consistent linear decreasing or increasing pattern. We found significant association between increased odds of developing isolated CL/P among cases with 20 to 24 year-old mothers (OR = 1.07, 1.01–1.13, p = 0.013), mothers who smoked 11 to 20 cigarettes per day (OR = 1.46, 1.33–1.60, p < 0.001), mothers with extreme obesity (OR = 1.32, 1.21–1.43, p < 0.001), mothers with grade II obesity (OR = 1.32, 1.23–1.42, p < 0.001), mothers with pre-pregnancy hypertension (OR = 1.17, 1.04–1.31, p = 0.009), mothers with pre-pregnancy diabetes mellitus (OR = 1.96, 1.71–2.25, p < 0.001), and mothers who used assisted reproductive technology (OR = 1.40, 1.18–1.66, p < 0.001).ConclusionsOur findings suggest a minuscule increase, albeit insignificant, in the trend of CL/P prevalence from 2016 to 2021. Developing CL/P had greater odds among mothers with pre-pregnancy diabetes, smoking, obesity, and pre-pregnancy hypertension mothers along with mothers who used assisted reproductive technology. Isolated CL/P had the highest prevalence in non-Hispanic Whites, American Indian or Alaskan Native and Native Hawaiian and Other Pacific Islanders.

Hematological profiles of newborns of mothers with hypertensive disorders of pregnancy delivered at the University of Gondar comprehensive specialized hospital: a comparative cross-sectional study

BackgroundHypertensive disorders in pregnancy can cause prenatal placental perfusion with insufficient blood supply to the fetus, resulting in fetal exposure to hypoxia and leading to disturbance of neonatal hematopoietic stem cells. This study aimed to compare the hematological profiles of newborns from mothers with hypertensive disorders and normotensive delivered at the University of Gondar comprehensive specialized hospital.MethodsA comparative cross-sectional study was conducted from March to May 2022 among 308 newborns from hypertensive and normotensive mothers in equal proportions. A systematic random sampling technique was used to select study participants. Three milliliters of cord blood were collected to perform a complete blood count by Beckman coulter. The results were presented using tables and graphs. Independent t-test and Mann-Whitney U test were done to compare the hematological profiles of the two groups. P-value < 0.05were considered statistically significant.ResultsThe majority of hypertensive and normotensive mothers’ ages were between 20 and 34 years (83.77% and 90.91%, respectively). The hematocrit levels were significantly higher in neonates of hypertensive mothers than the neonates of normotensive mothers (49.10 ± 5.19% and 46.09 ± 7.63% respectively) (P < 0.001) while neutrophil counts were significantly lower in neonates of hypertensive mothers than the neonates of normotensive mothers (6.62 ± 3.30 and 7.55 ± 3.31 × 103 /ul respectively) (P = 0.007). Also, platelets counts were significantly lower in neonates of hypertensive mothers than neonates of normotensive mothers (221.25 ± 83.56 and 260.24 ± 83.01 × 103/ul respectively) (P < 0.001). The platelet and nucleated red blood cell count showed a statistically significant difference among newborns from mothers with superimposed preeclampsia and gestational hypertension.ConclusionNewborns delivered from hypertensive disorders of pregnancy had low white blood cell parameters, low platelet count and high red blood cell parameters compared to controls. As result, newborns may develop leukopenia, thrombocytopenia and polycythemia, respectively. Therefore, newborns should be monitored for early detection and follow-up of hematological abnormalities before complications occurred.

Oral hygiene status and vascular aging in schoolchildren and their mothers.

Poor oral hygiene, generally manifesting as dental caries, gingivitis, or periodontitis, is a common chronic condition among both children and adults worldwide and has been reportedly associated with hypertension and arterial stiffness mainly in adult patients. However, these associations have not been well-studied in children and adults in the general population. Therefore, we conducted this cross-sectional study to clarify the associations between oral hygiene indices and high blood pressure (BP)/hypertension and arterial stiffness as assessed by the cardio-ankle vascular index (CAVI) in children along with their mothers. The association between maternal oral hygiene and high BP in children was also examined based on the hypothesis that maternal awareness of oral hygiene is related to their children's oral hygiene. This study was conducted as an Adjunct Study of the Aichi Regional Sub-Cohort of the Japan Environment and Children's Study. Participating children (n = 220, 85-104 months old) and their mothers (n = 217, 29-52 years old) underwent dental/intra-oral examination and BP and CAVI assessment. High BP in children and hypertension in mothers were diagnosed according to corresponding American guidelines. Logistic regression analysis or analysis of covariance was used to examine the associations of poor oral hygiene indices with BP and CAVI. Maternal dental caries ≥1 was associated with their hypertension (adjusted odds ratio [aOR]: 2.72, 95% confidence interval (CI): 1.12-6.61). Maternal dental plaque ≥1/3 was associated with maternal hypertension and children's high BP (aOR, 95% CI: 4.71, 1.33-16.73 and 5.67, 1.22-25.04, respectively). Maximum pocket depth ≥4 mm was associated with children's high BP (aOR: 6.85, 95% CI: 1.24-38.01). No associations were observed between oral hygiene indices and CAVI in children; however, there was a significant association between dental plaque and CAVI in mothers (F = 5.62, p < 0.01). The small sample size, especially the case number, made it necessary to refrain from drawing unambiguous conclusion. The hypothesis that warrants further investigation based on the present study results is that poor oral hygiene is associated with high BP in children and hypertension and arterial stiffness in mothers, and maternal oral hygiene is associated with high BP in children.

Outcomes of Women with Preeclampsia and Eclampsia Admitted in the Intensive Care Unit at a Tertiary Care Hospital in Mogadishu, Somalia.

Intensive care for a hypertensive mother with preeclampsia or eclampsia is crucial for both maternal and neonatal outcomes. This study highlights the level of morbidity and mortality among women with preeclampsia and eclampsia admitted to the intensive care unit. Methods. This retrospective study was conducted in Mogadishu, Somalia, at the Mogadishu Somali Türkiye Training and Research Hospital from February 2019 to July 2022. The study focused on the different complications, managements, and final outcomes of preeclampsia and eclampsia mothers admitted to the intensive care unit. The data was retrieved from the electronic records of patients admitted to the intensive care unit. Results. During our study period, a total of 237 patients were identified as having preeclampsia/eclampsia, of whom 71 required intensive care admission. The mean age of the studied patients was 25 ± 6 years. The most common reason for being taken to the intensive care unit (ICU) was having a seizure (n = 33, 46.5%), followed by having very high blood pressure (n = 20, 28.2%), and being confused (n = 18, 25.3%). Peripartum infection was the most common maternal complication during ICU admission (66.7%), followed by cardiac-related arrhythmia (66.7%), postpartum bleeding (48%), acute kidney injury (18.4%), HELLP syndrome (16.4%), severe anemia (9.6%), and stroke (8.7%). Among patients, 65 (91.5%) needed mechanical ventilation. About 11.1% of these patients died during hospitalization. There were associations between mortality and some complications, particularly acute kidney injury (p value less than 0.02) and peripartum infection (p value less than 0.003). Conclusion. Hypertensive disease of pregnancy (preeclampsia/eclampsia) requiring intensive care unit admission has a very high morbidity and mortality rate.

Comparison of placental expression of basic fibroblast growth factor and insulin-like growth factor-1 in placentae of normal, pregnancy-induced hypertension, and preeclamptic pregnancies in Iraqi mothers

Abstract Background: Many pathological insults are associated with elevation of blood pressure levels during pregnancy resulting in a difficult pregnancy and a poor outcome on both mother and baby. Objective: In this study, we examine the histological and immunohistochemical markers of the placentae in cases of hypertension in pregnancy and preeclampsia and compared them to a placenta of normal pregnancy among a random sample of Iraqi pregnant women. Materials and Methods: Ninety women divided into three groups, 30 in each, selected with straightforward pregnancies (Group A), mothers with pregnancy-induced hypertension (Group B), and preeclamptic mothers (Group C) were chosen from the indoor patients of the gynecology and obstetrics department of Al-Khansaa teaching hospital in Mosul for placental tissues examination. Histological examination was done by using hematoxylin and eosin stain (H &amp; E), and immunohistochemistry was achieved by using immunohistochemical markers named: insulin-like growth factor-1 (IGF-1) and basic fibroblast growth factor (b-FGF) markers, which are expressed in placental tissues. Results: Different changes were observed in the placentae affected when compared with normal one, such as syncytial knots formation, thickening of trophoblastic basement membrane, cytotrophoblastic cellular proliferation, fibrinoid necrosis, endothelial proliferation, calcified and hyalinised villous spots, villous edema, and atherosis of the uteroplacental arteries. Significant immunohistochemical changes were obtained when compared with normal placentae where elevation of both b-FGF and IGF-1 in preeclamptic placentae was observed when compared to hypertensive and control cases. Conclusion: Significant changes appeared in the placentae of hypertensive and preeclamptic mothers, both in histological and immunohistochemical examinations.

Birth outcomes in mothers with hypertensive disorders and polycystic ovary syndrome: a population-based cohort study.

Is polycystic ovary syndrome (PCOS) associated with higher risks of extreme birth size and/or preterm birth in mothers with different hypertension types? PCOS was associated with additional risks of preterm birth in mothers with chronic hypertension and in singleton pregnancies of mothers with pre-eclampsia, and with higher risks of offspring born large for gestational age (LGA) in mothers with gestational hypertension. Women with PCOS are more likely to develop gestational hypertension, pre-eclampsia, and chronic hypertension. Although adverse birth outcomes have been frequently reported in mothers with PCOS, such associations in the setting of a hypertensive disorder remain unknown. This is a population-based cohort study including all live births 2004-2014 in Finland (n = 652 732). To ensure diagnosis specificity, mothers with diagnoses that could cause signs and symptoms resembling PCOS were excluded. Maternal diagnoses of PCOS, gestational hypertension, chronic hypertension, and pre-eclampsia were identified from the Finnish national registries. Generalized estimating equation and multivariable logistic regression were used to assess the adjusted odds ratio (aOR) and 95% CIs of preterm birth, very preterm birth, and offspring being small for gestational age (SGA) or LGA in hypertensive mothers with or without PCOS, using normotensive mothers without PCOS as reference. Of 43 902 (6.7%) mothers with hypertensive disorders, 1709 (3.9%) had PCOS. Significant interactions were detected for PCOS with hypertension on preterm birth, very preterm birth, offspring born SGA and LGA (Fpreterm = 504.1, Pinteraction < 0.001; Fvery preterm = 124.2, Pinteraction < 0.001; FSGA = 99.5, Pinteraction < 0.001; FLGA = 2.7, Pinteraction = 0.012, respectively). Using mothers with no hypertensive disorder and no PCOS as reference, the risks of preterm and very preterm birth were overrepresented in non-PCOS mothers with chronic hypertension or pre-eclampsia. PCOS was associated with higher risks of preterm birth (aORPCOS 4.02, 3.14-5.15 vs aORnon-PCOS 2.51, 2.32-2.71) in mothers with chronic hypertension, with significant interaction between the exposures (F = 32.7, Pinteraction < 0.001). PCOS was also associated with a higher risk of preterm birth in singleton pregnancies of mothers with pre-eclampsia (aORPCOS 7.33, 5.92-9.06 vs aORnon-PCOS 5.72, 5.43-6.03; F = 50.0, Pinteraction < 0.001). Furthermore, the associations of PCOS comorbid with chronic hypertension or pre-eclampsia was detected also for spontaneous births. Moreover, the risk of offspring LGA was higher in mothers with PCOS and gestational hypertension although lower in those with gestational hypertension alone (aORPCOS 2.04, 1.48-2.80 vs aORnon-PCOS 0.80, 0.72-0.89; F = 9.7, Pinteraction = 0.002), whereas for offspring SGA, the risks were comparable between hypertensive mothers with and those without PCOS. Information on medication treatment, gestational weeks of onset for pre-eclampsia and gestational hypertension, weight gain during pregnancy, and PCOS phenotypes were not available. All diagnoses were retrieved from registries, representing only those seeking medical care for their symptoms. The ICD-9 codes used to identify PCOS before year 1996 are known to underestimate the prevalence of PCOS, while the inclusion of anovulatory infertility as PCOS might introduce an overrepresentation bias, although PCOS constitutes 80% of anovulatory infertility. The risk of very preterm birth in relation to maternal PCOS and hypertensive disorders should be interpreted with caution owing to limited sample sizes. Multifetal pregnancies among maternal PCOS were too few for a subgroup analysis. Moreover, ART included IVF/ICSI only. Potential effects of other treatments, such as ovulation induction, were not examined. PCOS was associated with additional risks of preterm birth or offspring being LGA in hypertensive mothers, which varied between hypertension types. The exacerbated risks highlight consideration of PCOS in pregnancy counseling and management for women with hypertensive disorders.

Assessing the Brainstem Auditory Evoked Potentials in Subjects with Family History of Hypertension.

Hypertension (HTN) has a genetic predisposition and it also impairs microcirculation, thereby, affecting the well vascularized structures like the brainstem and causing changes in Brainstem Auditory Evoked Potentials (BAEPs). To find out the usefulness of BAEPs as a screening tool in apparently healthy individuals with a family history of HTN. One hundred and ten volunteers, aged 17 to 23 years, were enrolled in the study as participants with proper consent. After excluding the subjects with existing diseases or co-morbidities (e.g. diabetes, HTN, schizophrenia, neuropathy, etc.), those on ototoxic or neurotoxic drugs, a preliminary physical examination was performed, following which BAEPs were recorded with a proper device. Statistical analysis is done with SPSS 2016 software using the chi-square test. A consistent distortion in the inter-peak latency of III-V waves is noted when a family history of HTN is present in either parent or maternal grandparents. Other statistically significant findings are present in V/I% (HTN in mother), wave I (HTN in paternal grandfather), wave III (HTN in maternal grandfather), and inter-peak latency I-V (HTN in maternal grandmother). BAEP may be used as a screening tool in individuals with a family history of HTN with supportive evidence from further studies in the near future.

To study the correlation between severe oligohydramnios with perinatal outcome along with histopathology of placenta

The aim: To study the correlation between severe oligohydramnios with perinatal outcome and the placenta's histopathology.&#x0D; Materials and methods: comprised of 100 patients with oligohydramnios diagnosed after 28 weeks of gestation, admitted on an emergency basis, both booked / unbooked, who were willing to cooperate, were chosen. All patients with oligohydramnios (AFI&lt;5 %) were included in the study.&#x0D; Results: 3 cases came with intra-uterine death. All three were totally unbooked cases. 2 preterm babies died neonatal intensive care unit after 4 days due to meconium aspiration syndrome. Thus the perinatal mortality was 5 %. 44 % of neonates required admission into the neonatal intensive care unit. In our study, it was found that neonatal mortality and morbidity increased significantly when oligohydramnios was associated with complications like IUGR and pregnancy-induced hypertension in mothers. All the cases associated with these histopathological changes had adverse perinatal outcomes. Hence estimation of the amount of liquor is important in the antenatal period because oligohydramnios gives insight into the associated maternal complications or fetal anomalies and has a significant bearing on the perinatal outcome. The placental examination will illuminate all the conditions affecting the perinatal outcome. Without associated complications, oligohydramnios does not have adverse perinatal outcomes.&#x0D; Conclusions: Thus, in cases of oligohydramnios with no associated complications, expectant management can be tried for a better fetal outcome. Only oligohydramnios may be the first sign of placental insufficiency and an independent manifestation of the placental-related complications spectrum.

Study of incidence, risk factors and immediate outcome of hypoglycemia in neonates admitted in NICU

Background: Hypoglycemia is the most common metabolic problem occurring in newborns which is associated with poor neurologic outcome. The present study was conducted to determine the incidence, risk factors and immediate outcome of hypoglycemia in neonates. Methods: The present study was conducted on 3776 babies born with risk factors for hypoglycemia in NICU. Screening for blood glucose level of study subjects were done at 2, 4, 6,12,24,48,78 hours of life, twice daily and whenever symptomatic by using glucometer. Babies were followed up till discharge. Incidence, risk factors and immediate outcome of hypoglycemia were assessed. Appropriate tests were applied. Results: Incidence of hypoglycemia was 9.93% among high-risk neonates and overall incidence was 5.20%. 54.13% were males. 45% were preterm, 78.7% neonates were LBW. 53.07% were born to primiparous mother, 20.5% to diabetic mothers and 28.5% to hypertensive mothers. 16.8% had perinatal asphyxia, 14.66% new-born had underlying RDS. 48.5% were symptomatic, most common being lethargy 52.75% followed by jitteriness 43.41%, convulsion in 63 (34.62%). Preterm and LBW were significantly associated with mortality. Most common underlying comorbidities associated with deaths were sepsis (59.10%), RDS (45.46%), perinatal asphyxia (13.64%) and meconium aspiration syndrome (4.55%). Conclusions: Neonates with one or more risk factors for hypoglycemia should be screened irrespective of symptoms within 72 hours of life. Focused counselling on early initiation of breast feeding will reduce the incidence of hypoglycemia and its complications.

Risk of Adult Hypertension in Offspring From Pregnancies Complicated by Hypertension: Population-Based Estimates.

Hypertensive disorders of pregnancy (HDP) have been associated with an increased risk of chronic hypertension for both mothers and offspring. We sought to quantify the incidence of chronic hypertension in offspring from HDP-affected pregnancies in a large, population-based cohort study. Furthermore, we evaluate the association of HDP exposure in utero and maternal chronic hypertension in offspring. We performed a population-based cohort study of 8755 individuals born during 1976 to 1982 to 7544 women who all resided in the same community at the time of delivery. HDP were identified using a previously validated algorithm. Diagnosis of chronic hypertension in mothers and their offspring was determined using diagnostic codes. Cox proportional hazards regression was used to assess the association between HDP and chronic hypertension. HDP exposure (hazard ratio, 1.50 [95% CI, 1.18-1.90]) and maternal chronic hypertension (hazard ratio, 1.73 [95% CI, 1.48-2.02]) were both associated with a significant increased risk for chronic hypertension in offspring. Both risk factors remained significantly associated with increased risk of hypertension in offspring when included together in a multivariate model. Having both exposures was associated with a 2.4-fold increase in the risk of hypertension in offspring, suggesting a synergistic additive interaction. HDP exposure in gestation and maternal hypertension are both independently associated with an increased risk of chronic hypertension in offspring. Our results suggest that HDP exposure in utero, in addition to maternal chronic hypertension, may lead to a greater risk for the development of hypertension in offspring.
