RESUMEN

INTRODUCTION: Unplanned out-of-hospital births are very rare in the ambulance service and there is evidence that emergency paramedics do not feel comfortable with this operational picture. At the same time, there is an increased of morbidity and mortality for both the mother and the newborn. The aims of the present cross-sectional study were to identify insecurities of emergency paramedics in connection with unplanned out-of-hospital births, to analyse the reasons for this and to derive possible support measures to be implemented. MATERIAL AND METHODS: This study is a quantitative cross-sectional study examining management of unplanned out-of-hospital births by paramedics using a self-designed questionnaire. 65 participants took part in the online survey during the period from April 6, 2022 to April 30, 2022. SPSS was used for statistical data analysis. The central tendency of various influencing variables was examined with the help of the Mann-Whitney U test, the significance level was α<0.05. RESULTS: On average, preparation Median (IQR): 2.0 (1.0) and safety with the measures to be performed 3.0 (01.0), as well as knowledge about unplanned out-of-hospital births 2.0 (1.0) were rated moderately well. The participating paramedics had particular difficulties with the documentation of the birth process 3.0 (1.0). There was a great deal of respect for out-of-hospital birth attendance among participants 1.0 (1.0). Participation in an interdisciplinary simulation session appeared to have had a positive influence on the handling and preparation for safety in the measures to be taken (p=0.016). CONCLUSION: Insecurites as well as possible reasons for them could be identified. Possible suggestions for improvement for emergency paramedics in unplanned out-of-hospital births were developed. For example, specific birth protocols and participation in a simulation are good ways to help.

RESUMEN

OBJECTIVE: To investigate how often antenatal corticosteroids (ACS) were administered within the optimal time frame in women at risk of preterm birth (PTB) in relation to several diagnoses and risk factors. METHOD: The study was designed as a retrospective cohort trial, in which the data of all births taking place in 2016 in the German federal state of Rhineland-Palatinate were evaluated. Frequency analyses, subgroup analyses, and logistic regression were performed. RESULTS: Birth occurred within the ideal time frame (≥24 h, ≤7 days) in only 15.2% of all pregnant women who were treated with ACS because of an increased risk of PTB (N = 1544). The ideal time frame after ACS administration was reached in less than 25% of all cases in each subgroup, with little difference between the different diagnoses and risk factors for PTB (range 11.3%-22.2%). Patients with multiple pregnancy had a significantly higher chance for delivery within the ideal time frame. There was an odds ratio greater than 1 for a birth event within the ideal time frame in patients with preterm prelabor rupture of membranes, pre-eclampsia, oligohydramnios, amniotic infection syndrome, and in patients with multiple diagnoses. In most diagnoses, the average time between ACS administration and birth was significantly shorter compared with patients without the diagnosis or risk factor. CONCLUSION: In women at risk of PTB, the individual risk profile should first be identified before ACS management begins. The likelihood of achieving the ideal time frame additionally depends on the diagnosis.

RESUMEN

INTRODUCTION: Anemia and iron deficiency are the most common pathologies in pregnancy and associated with adverse pregnancy outcome. As patients with rheumatic diseases are also at high risk for anemia, we aimed to investigate the frequency of anemia and iron deficiency during pregnancy in this group and whether anemia is a risk factor for adverse maternal or child outcome. METHODS: We analyzed 368 pregnancies from a German registry for pregnancies in patients with rheumatic diseases (TURIRE) from 2014-2022. Anemia and iron deficiency were defined according to the World Health Organization. Main outcome measures were prevalence of anemia, iron deficiency, and adverse outcomes. RESULTS: From the 368 patients 61% were diagnosed with a connective tissue disease, 16% with rheumatoid arthritis or juvenile idiopathic arthritis, 14% with spondyloarthritis, 3% with vasculitis and 7% with other. Prevalence of anemia/iron deficiency was 18%/28% in the first, 27%/51% in the second and 33%/62% in the third trimester. Low hemoglobin levels (OR 0.52) or iron deficiency (OR 0.86) had a negative impact on child outcome. However, lower hemoglobin levels were associated with a lower risk for maternal complications (OR 1.47). CONCLUSION: Prevalence of anemia and iron deficiency is high in pregnant women with rheumatic diseases. Compared to previously published cohorts of the general population from different countries, the prevalence of anemia and iron deficiency is distinctly higher. Furthermore, patients with rheumatic diseases already start with impaired iron storage and/or hemoglobin levels. Thus, iron supplementation should be initiated early on in this vulnerable in this patient group.

RESUMEN

Prevalence rates of peripartum depression and anxiety are high and correlate with adverse maternal and neonatal outcomes. Mindfulness-based interventions (MBI) have been shown to reduce mental distress during pregnancy. A multicenter, randomized controlled study was conducted after screening for depressive symptoms. The intervention group (IG) was given access to an 8-week supervised eMBI between weeks 29 and 36 of pregnancy and followed up to 5 months postpartum. Psychometric data were collected using the Edinburgh Postnatal Depression Scale (EPDS), the State-Trait Anxiety Inventory (STAI), the Pregnancy-Related Anxiety Questionnaire (PRAQ-R), the Freiburg Mindfulness Inventory (FMI-14) as well as the Patient Health Questionnaire (PHQ). Out of 5299 pregnant women, 1153 scored >9 on the EPDS and N = 460 were included in the RCT. No significant interaction effects for depressive symptoms and anxiety were found. Pregnancy- and birth-related anxiety decreased significantly in the IG and 6 weeks after birth, the rate of women at risk for adverse mental outcome was significantly lower compared to the CG. Mindfulness scores improved significantly in the IG. The eMBI program did not show effective regarding general depressive or anxiety symptoms, however, positive results were demonstrated regarding pregnancy and birth-related anxiety and the prevention of postpartum depression.

RESUMEN

Background: The aim was to investigate gestational age at birth of women after induction of fetal lung maturation (antenatal corticosteroids = ACS) because of imminent preterm birth (PTB), and to quantify incidence of late PTB (gestational age < 260 days) and extreme immaturity (gestational age < 196 days) in relation to several diagnoses (PPROM, placental bleeding, premature labor, preeclampsia, oligohydramnios, amniotic infection syndrome (AIS), cervical insufficiency) and risk factors (age > 35, history of preterm delivery, multifetal gestation, gestational diabetes, hypertension, nicotine abuse). Methods: The study was designed as a retrospective cohort trial, in which the data of all births taking place in 2016 in the German federal state Rhineland-Palatinate were evaluated. Frequency analyses, subgroup analysis (Chi-square tests and Friedman's tests), as well as multinomial logistic regressions and linear regressions were used to determine odds ratios (OR). Results: In total, N = 1,544 patients were included who had been hospitalized due to an imminent PTB and had received ACS, of whom 52% had a late PTB and 8% a PTB with extreme immaturity. Regarding the gestational age at birth, there were only minor differences between the individual risk factors and diagnoses, only AIS patients showed a significantly lower gestational age (mean: 207 days). A significantly increased risk of PTB with extreme immaturity was found in patients with AIS (OR = 5.57) or placental bleeding (OR = 2.10). Conclusion: There is a need for further research in order to be able to apply therapeutic measures more accurately in relation to risk factors and diagnoses.

RESUMEN

Preterm birth serves as one of the leading causes of neonatal mortality worldwide. The underlying mechanisms that contribute to preterm birth are not yet fully understood. However, an association between periodontitis and preterm birth has been proposed. The periodontal status and presence of periodontal pathogens in women with different birth outcomes have been previously examined. However, varying definitions of periodontitis and different microbiological methods make their interpretation challenging. The aim of this case-control study on women with and without preterm birth was to investigate their periodontal status using the current classification system for periodontal diseases. Moreover, differences in the periodontal microbiome of the study participants were investigated. Therefore, we collected data on oral and periodontal parameters in 77 puerperal women divided into two groups based on gestational age at delivery: 33 patients with preterm birth (PTB, <37 weeks) and 44 patients with term birth (TB, >37 weeks). These data included pocket probing depth (PPD), clinical attachment loss (CAL), bleeding on probing (BOP), gingival-bleeding index, DMFT index, and gynecologic and dental history. In addition, their oral microbiome was explored. Median CAL and percentage PPD ≥ 4 mm were significantly higher in the PTB group than in the TB group (p = 0.0128 and p = 0.047, respectively). Birth weight was significantly higher in periodontally healthy women than in those with gingivitis (p = 0.0078) or periodontitis (p = 0.0127). The periodontal microbiome differed significantly between groups. Our results are underlining the possible association between periodontitis and preterm delivery. Women with periodontitis had babies with significantly lower birth weights. The microbiome varied between the groups.

RESUMEN

Introduction During the COVID-19 pandemic, stress and anxiety in the population increased due to concerns about people's own health and that of their relatives, as well as changes in everyday life due to measures taken to reduce the infection rate. Pregnant women are particularly stressed. The present study examines how the COVID-19 pandemic affects the stress experience and mental health of pregnant women and mothers of newborns and how care could be optimized. Methods As part of the international COVGEN initiative ( https://www.covgen.org ) to investigate the effects of the COVID-19 pandemic on the peripartum period, pregnant and postpartum women were asked about their experience with stress using the COPE-IS (Coronavirus Perinatal Experiences - Impact Survey) questionnaire developed for this purpose and translated from the English. In addition, demographic data, pre-existing diseases, pregnancy complications and the care situation were recorded. The questionnaire was either administered as hardcopy to inpatients at the Department of Women's Health, University Hospital Tübingen, Germany, or online. All pregnant women and mothers who were pregnant or had given birth after the official start of the COVID-19 pandemic (11 March 2020) were eligible to participate. Results Complete data sets of n = 156 pregnant women and n = 221 postpartum women were available for evaluation. The general stress level assessed with the COPE-IS was significantly increased by the COVID-19 pandemic in both, pregnant and postpartum women, with pre-existing conditions such as respiratory diseases and pregnancy-related diseases like gestational diabetes adding to the stress. The subjectively perceived quality of care/support during pregnancy also influenced the stress level. Conclusions Fears of a COVID-19 infection and changes in preventive and aftercare services were a burden for the women surveyed. Intensified care during pregnancy and puerperium could help to stabilize the mental situation and reduce stress.

RESUMEN

BACKGROUND: Optimal mode of birth for twins, in particular monochorionic twins, has been the subject of much debate. This retrospective study compared maternal and newborn outcomes after vaginal birth in monochorionic and dichorionic twins, utilizing a large institutional database. METHODS: Retrospective analysis focusing on 98 monochorionic-diamniotic (MC-DA) and 540 dichorionic-diamniotic (DC-DA) twin births extracted from the perinatal database of a large German hospital. Pregnancies ≥36 weeks of gestation with two viable foetuses born between 2004 and 2014 divided into planned vaginal and planned caesarean delivery were included. Descriptive analysis was performed for maternal characteristics. Odds ratios (OR) with 95% confidences intervals (CI) tested the predictive effect of vaginal birth on neonatal and maternal outcomes. RESULTS: 51.0% MC-DA and 46.7% DC-DA twin pregnancies were planned vaginal births and 44.0% MC-DA mothers and 43.7% DC-DA mothers actually gave birth vaginally. The overall rate of caesarean section (CS) during the years under observation was 79.6% for MC-DA and 77.0% for DC-DA pregnancies. There were no significant differences in neonatal outcome between the subsamples, although acidosis was observed more often in the second DC-DA twin and Apgar scores < 7 were observed more often in MC-DA twins. CONCLUSION: Vaginal birth may be recommended as an option to women with monochorionic twins as no significant differences in outcomes were found between MC-DA and DC-DA twins. However, over half of planned vaginal twin births resulted in CS.

RESUMEN

INTRODUCTION: Even well-treated gestational diabetes mellitus (GDM) might still have impact on long-term health of the mother and her offspring, although this relationship has not yet been conclusively studied. Using in-depth phenotyping of the mother and her offspring, we aim to elucidate the relationship of maternal hyperglycaemia during pregnancy and adequate treatment, and its impact on the long-term health of both mother and child. METHODS: The multicentre PREG study, a prospective cohort study, is designed to metabolically and phenotypically characterise women with a 75-g five-point oral glucose tolerance test (OGTT) during, and repeatedly after pregnancy. Outcome measures are maternal glycaemia during OGTTs, birth outcome and the health and growth development of the offspring. The children of the study participants are followed up until adulthood with developmental tests and metabolic and epigenetic phenotyping in the PREG Offspring study. A total of 800 women (600 with GDM, 200 controls) will be recruited. ETHICS AND DISSEMINATION: The study protocol has been approved by all local ethics committees. Results will be disseminated via conference presentations and peer-reviewed publications. TRIAL REGISTRATION NUMBER: The PREG study and the PREG Offspring study are registered with Clinical Trials (ClinicalTrials.gov identifiers: NCT04270578, NCT04722900).

RESUMEN

BACKGROUND: This study investigates the influence of maternal stress during pregnancy on maternal insulin sensitivity and Interleukin-6 (IL-6) levels in pregnant women (N = 277) in dependence of pre-pregnancy Body-Mass-Index (BMI). METHODS: Gestational diabetes was diagnosed in 80 women. We used the Patient Health Questionnaire (PHQ-D) to investigate maternal stress during pregnancy with a higher scoring indicating higher maternal stress level. IL-6 and cortisol were measured and maternal insulin sensitivity was assessed with the non-esterified fatty acid insulin sensitivity index (NEFA-ISI). Generalized Linear Model analysis was used to analyze effects within different stress groups. RESULTS: Maternal low stress symptoms during pregnancy showed no significant association with maternal insulin sensitivity or IL-6. Higher cortisol levels during pregnancy were associated with elevated IL-6 concentrations. Pre-pregnancy BMI had the strongest positive effect on IL-6 levels and was negatively associated with insulin sensitivity during pregnancy. CONCLUSIONS: Therefore, preconceptional interventions to reduce BMI are needed to improve maternal metabolism during pregnancy.

RESUMEN

PURPOSE: Budd-Chiari syndrome (BCS) is a rare disease characterized by hepatic venous outflow tract obstruction. The study aimed to evaluate the diagnostic utility of ultrasound in confirming the diagnosis of BCS and to provide an overview of the clinical picture. MATERIALS AND METHOD: In this retrospective single-center study, patients with an initial diagnosis of BCS were included. The files were analyzed concerning the ultrasound images and compared to computed tomography (CT) and magnetic resonance imaging (MRI). Main clinical signs of BCS were collected. RESULTS: Data of 25 patients were analyzed. Doppler sonography showed the highest sensitivity (78.9%) with the highest specificity 97.4 (%) in confirming the correct diagnosis of BCS. Main imaging signs were obstruction in the hepatic veins (68.0%, 17/25 thrombotic), collaterals (91.7%, 11/12 intrahepatic), inhomogeneous liver parenchyma (7/21), and a hypertrophied lobus caudatus (18/21) (p < 0.01). All imaging signs could be detected with sonography. Hypertrophied lobus caudatus was seen exclusively in BCS. Furthermore, portal hypertension (9/25), liver cirrhosis (9/25), and ascites (19/25) can be diagnosed as non-specific signs of BCS (p < 0.01).The main clinical findings were elevated γ-GT levels in the laboratory (92.0%, 23/25, p < 0.01) and esophageal varices in endoscopy (12/25 p < 0.01). An association with myeloproliferative neoplasia (MPN) was frequently seen (10/25) (p < 0.01). CONCLUSION: The present study demonstrates that sonography is an appropriate tool for the diagnosis of BCS and should be used as the first imaging procedure.

RESUMEN

BACKGROUND: Offspring of mothers with gestational diabetes mellitus (GDM) have an increased risk of neonatal complications like birth trauma due to macrosomia or postnatal hypoglycemia, as well as long-term metabolic sequelae. Neonatal body composition may be a sensitive marker of metabolic effects on the fetus caused by suboptimal glycemic control during pregnancy. OBJECTIVE: To determine body composition in offspring of mothers with GDM compared to a reference cohort of healthy term neonates and to assess whether increased body fat would be associated with postnatal hypoglycemia. METHODS: This prospective, observational, cross-sectional study included 311 full-term, singleton infants born between June 2014 and July 2015. Body composition was measured within 96 h of birth using air displacement plethysmography. Results are indicated as median (1st Quartile - 3rd Quartile). RESULTS: Of 311 infants, 40 (12.9%) were born to mothers with GDM. Birth weight standard deviation scores (SDS) (0.24 vs. - 0.07, p = 0.04), fat mass (370 g vs. 333 g, p = 0.02) as well as fat mass/total body mass (BF%; 11.4% vs. 10.8%, p = 0.03) were significantly higher in infants following maternal GDM than in controls. In GDM offspring, anthropometric parameters, fat mass or BF% did not differ between infants with or without postnatal hypoglycemia. In this cohort, SDS for birth weight, fat mass, fat free mass, BF% or postnatal hypoglycemia were not associated with maternal blood glucose levels measured at an oral glucose tolerance test. CONCLUSIONS: SDS for birth weight, neonatal fat mass, and BF% were significantly higher in newborns following maternal GDM. In these infants born to mothers with GDM, body composition did not differ between those with or without postnatal hypoglycemia.

RESUMEN

Peritoneal mucosa of mesothelial cells line the abdominal cavity, surround intestinal organs and the female reproductive organs and are responsible for immunological integrity, organ functionality and regeneration. Peritoneal diseases range from inflammation, adhesions, endometriosis, and cancer. Efficient technologies to isolate and cultivate healthy patient-derived mesothelial cells with maximal purity enable the generation of capable 2D and 3D as well as in vivo-like microfluidic cell culture models to investigate pathomechanisms and treatment strategies. Here, we describe a new and easily reproducible technique for the isolation and culture of primary human mesothelial cells from laparoscopic peritoneal wash cytology. We established a protocol containing multiple washing and centrifugation steps, followed by cell culture at the highest purity and over multiple passages. Isolated peritoneal mesothelial cells were characterized in detail, utilizing brightfield and immunofluorescence microscopy, flow cytometry as well as Raman microspectroscopy and multivariate data analysis. Thereby, cytokeratin expression enabled specific discrimination from primary peritoneal human fibroblasts. Raman microspectroscopy and imaging were used to study morphology and biochemical properties of primary mesothelial cell culture compared to cryo-fixed and cryo-sectioned peritoneal tissue.

RESUMEN

Maternal metabolism and intrauterine conditions influence development of health and disease in offspring, leading to metabolic, physiologic, and/or epigenetic adaptation of the fetus. Maternal gestational diabetes (GDM) leads to higher incidence of obesity and type 2 diabetes in offspring. We have previously shown that fetuses of insulin-resistant mothers with GDM have a delayed reaction to auditory stimuli in the postprandial state, indicating a fetal central insulin resistance. We tested whether this effect could be influenced by a lifestyle intervention in mothers with GDM, including diet counselling and regular blood glucose measurements. We measured fetal brain activity over the course of a maternal glucose challenge, at two measurement time points (baseline at an average of 29 weeks of gestation and follow-up after 4 weeks) in mothers with GDM and mothers with normal glucose tolerance (NGT). Data from eight mothers were able to be included. Fetuses of GDM mothers showed longer latencies than those of NGT mothers postprandially at both measurement time points during the third trimester and did not show a difference in response patterns between baseline and after 4 weeks. Maternal postprandial blood glucose and insulin values did not change from baseline to follow-up either. While the overall intervention seems to have been effective, it does not appear to have influenced the fetal postprandial brain responses. This might have been because interventions for GDM take place relatively late in pregnancy. Future research should focus on maternal lifestyle interventions as early as possible during gestation, or even prenatally.

RESUMEN

INTRODUCTION: Reliability in the use of placentome (including placenta, umbilical cord, and cord blood) biomarkers requires an understanding of their distributions. Here we aim to develop a simple and proper placenta sampling scheme, and to evaluate the placental distributions of biomarkers. METHODS: We developed a continuous cooling chain protocol off delivery room and cryo-subsampling method for placenta sampling. The levels of thyroid hormones (THs), elements, persistent organic pollutants (POPs), monoamines, and vitamin E were measured using UPLC-Q-TOF-MS, HPLC-ICP-MS, HPLC-EcD, and HRGC-HRMS, respectively. The distributions of biomarkers were assessed. RESULTS: In human placentome, l-thyroxine (T4), Cd, Se, Zn, Cu, Fe, Ca, K, Mg, α-tocopherol, ß-tocopherol, and ß-tocotrienol levels were higher in placenta than in umbilical cord, while Pb and Mn were concentrated in human cord. In porcine placentome, T4, 3,3',5'-triiodo-l-thyronine (rT3), 3,3'-diiodo-l-thyronine, Cd, Pb, Zn, K, and Al levels were higher in the cord. The intraclass correlation coefficient (ICC) was <0.4 for 3,3',5-triiodo-l-thyronine, rT3, α-tocopherol, and 7 elements in human basal plate, indicating low reliability. rT3, Cd, Zn, Mn, and Cu were significantly concentrated in the central region in human placenta, while higher levels of As, Cd, Cr, and Al were found in the periphery region in porcine placenta. Polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) showed moderate reliability (ICC: 0.40-0.98) except PCB-81, -126, and BDE-208, while polychlorinated dibenzo-p-doixins/furans (PCDD/Fs) showed poor reliability (ICC: 0.07-0.31). DISCUSSION: These results highlight the complexity of placenta sampling. This study provides a novel and simple sampling approach in investigating placental exposomics.

RESUMEN

Before and during pregnancy, women often aim to improve their lifestyle so as to provide a healthier environment for their developing child. It remains unresolved, however, as to whether physical activity (PA) during pregnancy poses a possible risk or whether it might even have beneficial effects on the developing child. There is increasing evidence that PA during pregnancy is indeed beneficial to maternal physiological and psychological health and that it is generally not detrimental to the fetal cardiovascular system and neuronal function in the developing child. This also led to international recommendations for PAs during pregnancy. In the current review, we aimed to comprehensively assess the evidence of beneficial and harmful effects of maternal PA, including high-performance sports, on fetal development. The different mental and body-based relaxation techniques presented here are frequently performed during pregnancy. We found a considerable number of studies addressing these issues. In general, neither low key, moderate maternal PA nor relaxation techniques were observed to have a harmful effect on the developing child. However, we identified some forms of PA which could have at least a transient unfavourable effect. Notably, the literature currently available does not provide enough evidence to enable us to make a general conclusive statement on this subject. This is due to the lack of longitudinal studies on the metabolic and cognitive effects of regular PA during pregnancy and the wide diversity of methods used. In particular, the kind of PA investigated in each study differed from study to study.

RESUMEN

PURPOSE: The aim of the current study was to evaluate point of care ultrasound (POCUS) in geriatric patients by echoscopy using a handheld ultrasound device (HHUSD, VScan) at bedside in comparison to a high-end ultrasound system (HEUS) as the gold standard. MATERIALS AND METHODS: Prospective observational study with a total of 112 geriatric patients. The ultrasound examinations were independently performed by two experienced blinded examiners with a portable handheld device and a high-end ultrasound device. The findings were compared with respect to diagnostic findings and therapeutic implications. RESULTS: The main indications for the ultrasound examinations were dyspnea (44.6 %), fall (frailty) (24.1 %) and fever (21.4 %). The most frequently found diagnoses were cystic lesions 32.1 % (35/109), hepatic vein congestion 19.3 % (21/109) and ascites 13.6 % (15/110). HHUSD delivered 13 false-negative findings in the abdomen resulting in an "overall sensitivity" of 89.5 %. The respective "overall specificity" was 99.6 % (7 false-positive diagnoses). HHUSD (versus HEUS data) resulted in 13.6 % (17.3 %) diagnostically relevant procedures in the abdomen and 0.9 % (0.9 %) in the thorax. Without HHUSD (HEUS) 95.7 % (100 %) of important pathological findings would have been missed. CONCLUSION: The small HHUSD tool improves clinical decision-making in immobile geriatric patients at the point of care (geriatric ward). In most cases, HHUSD allows sufficiently accurate yes/no diagnoses already at the bedside, thereby clarifying the leading symptoms for early clinical decision-making.

RESUMEN

OBJECTIVE: Prepregnancy obesity and extensive weight gain can lead to diseases in the offspring later in life. The aim of this study was to evaluate the effect of anthropometric and metabolic factors on the fetal autonomic nervous system (ANS) in uncomplicated pregnancies. METHODS: A total of 184 pregnant women in the second or third trimester were included, and for 104 women, maternal insulin sensitivity (ISI) was determined. Fetal heart rate (HR) and heart rate variability (HRV) were determined by magnetic recording. Associations of maternal prepregnancy BMI, weight gain, and ISI with fetal HR and HRV were evaluated by ANCOVA, partial correlation, and mediation analysis. RESULTS: HR was increased and HRV decreased in fetuses of mothers with overweight or obesity in comparison to normal-weight mothers. Fetal HR was negatively correlated with maternal weight gain. Maternal prepregnancy BMI was positively correlated with fetal high frequency and was negatively correlated with low frequency and low/high frequency ratio. Maternal ISI showed a negative correlation with fetal HR. CONCLUSIONS: The results show that the fetal ANS is sensitive to alterations of prepregnancy BMI, weight changes, and glucose metabolism. These findings highlight the importance of the intrauterine environment on the developing ANS and the possible programming of obesity.

RESUMEN

BACKGROUND: During pregnancy, a variety of factors can influence fetal growth and development. Intrauterine growth may impact on later life and health. Neonatal body composition may be a more sensitive marker for the intrauterine environment than established anthropometric parameters at birth. METHODS: To study neonatal body composition determined by air displacement plethysmography in healthy, term singletons as national reference data, and to establish factors impacting on neonatal body composition in this population. This prospective cross-sectional observational study included 271 healthy, full-term, singletons born between June 2014 and July 2015. Body composition was measured within 96 h of birth using air displacement plethysmography. RESULTS: Median (Q1, Q2) fat mass / total body mass (BF%) in German singletons was 10.8% (7.7-13.4) and fat free mass (FFM) 2843 g (2606-3099). Female infants had significantly increased BF% compared to male infants (11.2% (8.7-14.0) vs. 9.6% (7.2-12.1)). On multiple regression analysis, BF% and fat mass increased with female gender, maternal pre-pregnancy body mass index, non-smoking mother and parity, whereas FFM increased with male gender and increasing gestational age at birth. Gestational weight gain category, birth mode, and postnatal age at measurement were not associated with BF%, FFM or fat mass. CONCLUSIONS: We generated BF% and FFM centiles for healthy, term, singletons born in Germany; these are similar to those found in other European countries. Infant body composition at birth was associated with modifiable (pre-pregnancy body mass index, smoking), and given factors (gender, gestational age at birth, parity).
