Implementation of safe infant sleep recommendations during night-time sleep in the first year of life in a German birth cohort.

The aim of our study was to assess the extent to which families followed recommendations, issued by the German society for sleep medicine, for the prevention of sudden infant death syndrome (SIDS) during night-time sleep. Analyzing longitudinal data from a birth cohort located at the University Children's Hospital Regensburg in Bavaria (Germany), we determined data regarding the infant's sleep location, sleep settings and body position, and exposure to environmental factors. Data were collected in a structured interview after birth and by standardized questionnaires at 4 weeks, 6 months, and 1 year of life, respectively. The majority of 1,400 surveyed infants (94% at 4 weeks) were reported to sleep in the parents' sleeping room during the first months of life. While the most common furniture was a bedside sleeper (used by 48%), we also observed a considerable proportion of families who regularly practiced bed-sharing and, for 16% of infants, the parents' bed was the default sleeping place. 12% of infants were still put regularly in the prone position. The vast majority (87%) of the infants were breastfed at some timepoint and 17% lived in a household with one or more smokers. Although most parents implemented many SIDS recommendations, our analysis illustrates a considerable gap between recommendations and intentions after birth on the one hand and actual implementation in real life on the other. The number-one deviation from the current SIDS guidelines during night-time sleep was bed-sharing with an adult.

Maternal knowledge of recommendations for safe infant sleep and intentions for implementation - a cross sectional analysis of data from the KUNO-Kids birth cohort study.

OBJECTIVES: Despite major advances in prevention, sudden infant death syndrome (SIDS) remains an important cause of infant mortality. The aim of our study was to determine actual knowledge and intentions to implement SIDS prevention measures among new mothers and to identify potential knowledge gaps for improved postpartum counselling strategies. METHODS: Data was collected in a standardized interview from participants of the KUNO-Kids birth cohort study before discharge from maternity ward. The mothers did not receive any specific teaching prior to the interview. RESULTS: The majority of 2,526 interviewed mothers were able to actively report important recommendations for safe infant sleep, including the exclusive face-up position. However, 154 mothers (9%) intended to position the newborn face-down sometimes or often. The most frequently envisaged sleeping furniture was a bedside sleeper (n=1,144, 47%), but 2.2% of mothers indicated that the intended default sleeping place for the newborn would be the parents' bed (which is discouraged by the recommendations). For 43% of the infants (n=1,079), mothers planned to have loose objects in the bed and 189 mothers (7%) intended to use a loose blanket. 22% of infants (n=554) will live in a household with a smoker. Multivariate regression showed a significant association of "good knowledge" with maternal age and with not being a single parent, whereas the household size was negatively associated. CONCLUSION: Although the majority of mothers in our birth cohort were aware of many recommendations for safe infant sleep, our data also uncovered weaknesses in SIDS prevention knowledge and point to specific areas with potential for improved counselling.

Prevalences of cardiometabolic risk and lifestyle factors in young parents: evidence from a German birth cohort study.

BACKGROUND: Studies show that parents significantly impact their children's health through their cardiometabolic risk profile and health behavior. There is only little information about the prevalence of cardiometabolic risk factors and lifestyle factors among new parents yet. The aims of this study are therefore to evaluate the prevalences of cardiometabolic risk factors in parents of infants in Germany and to examine their lifestyle and health behavior. METHODS: In the KUNO-Kids health study, an ongoing birth cohort, parents (n = 930 mothers and 769 fathers) were asked about cardiometabolic risk factors (obesity/hypertension/type 2 diabetes mellitus) and lifestyle factors (dietary/sports/smoking habits/alcohol consumption) during the first year after the birth of their children via questionnaires. Chi-square as well as fisher exact tests were conducted to analyse associations between lifestyle factors and cardiometabolic risk factors. RESULTS: 34.2% of mothers and 58.5% of fathers were overweight or obese. In 11.8% of the families, at least one parent suffered from hypertension, in 2.4% from type 2 diabetes mellitus. One year after delivery, 8.5% of mothers were smoking, 6.9% showed a risky alcohol consumption (> 10 g/d). 16.0% of fathers were smoking 4 weeks after childbirth, 10.7% showed risky alcohol consumption (> 20 g/d). 21.6% of mothers carried out sports activity for more than 2 h a week then. Parental hypertension was linked to a higher prevalence of risky alcohol consumption, obesity to a lower prevalence of daily fruits consumption. CONCLUSIONS: Cardiometabolic risk factors were widespread among new parents with obesity and overweight having the highest prevalences. A considerable number of parents also practiced an unhealthy lifestyle showing that there is potential for improvement to promote the healthy development of their children.

Vaginal Delivery Is Associated with Neurochemical Evidence of Increased Neuroaxonal Remodelling in Infants from the KUNO-Kids Health Study: Cross-Sectional Analysis.

AIM: Little is known about neonatal brain plasticity or the impact of birth mode on neurointegrity. As a reflection of neuroaxonal damage, the neuronal structural protein neurofilament light chain (NfL) has emerged as a highly specific biomarker. Our purpose was to test the hypothesis that vaginal delivery is associated with increased NfL in neonates. METHODS: NfL concentrations were measured using single-molecule array immunoassay in umbilical cord serum from healthy term neonates enrolled in the prospective KUNO-Kids Health Study. NfL values were investigated for independent influencing factors using linear and logistic models, followed by post hoc propensity score-matching. RESULTS: Of 665 neonates, n = 470 (70.7%) were delivered vaginally and n = 195 (29.3%) by cesarean section. Median serum NfL was significantly higher after vaginal delivery 14.4 pg/mL (11.6-18.5) compared to primary 7.5 pg/mL (6.1-8.9) and secondary cesarean delivery 9.3 pg/mL (7.5-12.0). Multivariable logistic regression models showed delivery mode and gestational age to be independently associated with NfL. Propensity score-matching analysis confirmed that assisted vaginal delivery generated higher NfL compared to vaginal (non-assisted), while lowest levels were associated with cesarean section. INTERPRETATION: Our data confirm the significant impact of birth mode on neonatal NfL levels. The persistence of these differences and their potential long-term impact have yet to be investigated.

Utilisation of supplementary prenatal screening and diagnostics in Germany: cross-sectional study using data from the KUNO Kids Health Study.

BACKGROUND: Appropriate health system utilisation during pregnancy is fundamental for maintaining maternal and child's health. To study the use and determinants of supplementary prenatal screening and diagnostics in Germany this study provides comprehensive data. METHODS: We obtained data from a recently established prospective German birth cohort study, the KUNO Kids Health Study. Analyses are based on Andersen's Behavioural Model of health system use, which distinguishes between predisposing (e.g. country of birth), enabling (e.g. health insurance) and need factors (e.g. at-risk pregnancy). We examined bi- and multivariate association with the use of supplementary prenatal screening and diagnostics using logistic regression. RESULTS: The study has a sample size of 1886 participating mothers. One fifth of the mothers investigated did not use any supplementary prenatal screening or diagnostics. Notably, the chance of using supplementary prenatal screening and diagnostics more than doubled if the pregnant woman had a private health insurance (OR 2.336; 95% CI 1.527-3.573). Higher maternal age (OR 1.038; 95% CI 1.006-1.071) and environmental tobacco smoke exposure (OR 1.465 95% CI 1.071-2.004) increased the use of supplementary prenatal screening and diagnostics. However, regarding need factors only having an at-risk-pregnancy (OR 1.688; 95% CI 1.271-2.241) showed an independent association. CONCLUSION: The important role of the type of health insurance and the relatively small influence of need factors was surprising. Especially with respect to equity in accessing health care, this needs further attention.

Digital Media Exposure and Predictors for Screen Time in 12-Month-Old Children: A Cross-Sectional Analysis of Data From a German Birth Cohort.

Background: Early exposure to digital media may affect the physical and cognitive development in young children. The American Academy of Pediatrics and national guidelines recommend no digital media use at all under the age of 18 months. The aim of our study was to determine the actual exposure to digital media in 12-month-old infants and to reveal potential risk factors for screen time. Methods: In this prospective cross-sectional survey, data was collected from the KUNO Kids birth cohort study using parent-report questionnaires regarding the media exposure of the study child. We determined age at first contact with different digital media, mean screen time on an average weekday, and the influence of major demographic and socioeconomic factors. Results: Data for screen time analysis was available for 630 children. In summary, 45% of children had already been exposed to digital media by their first birthday. The most frequent first digital media exposure was the TV (33.0%) followed by smartphones (16.9%), both most commonly exposed to around the age of 8 months. On a regular weekday, 20% of the children spent 0.5-1 h in front of a TV and 9% were exposed to a smartphone for the same time frame, compared to 31% of joint parent-child media use. Predictors for screen time were having one sibling, less living space per person, and excessive TV use in the household, the latter of which doubled the chance of the child being exposed to digital media. Conclusion: A proportion of 10% of 1-year-old children were already regularly exposed to digital media. The TV remains the most predominant device but new media, particularly smartphones, might be catching up. Our study provides further support that family TV time is a major predictor of infant screen time. Pediatric recommendations should be re-evaluated in the light of the actual exposure to digital media already in infancy and parents should be proactively counseled regarding possible effects on child development.

Prevalence of and factors associated with receipt of provider recommendation for influenza vaccination and uptake of influenza vaccination during pregnancy: cross-sectional study.

BACKGROUND: Seasonal influenza vaccination has been recommended for pregnant women in Germany since 2010. The aim of this study was to examine prevalence and determinants of receipt of provider recommendation for influenza vaccination as well as influenza vaccination uptake during pregnancy. METHODS: We analysed data from the "KUNO Kids Health Study", a prospective birth cohort. During the study period (5th July 2015 to 27th June 2018) data were collected from participating mothers by interview and questionnaire. According to Andersen's behavioural model of health services use potential influencing factors describing the circumstances and characteristics of the mothers and their pregnancies which are potentially affecting whether women receive a recommendation for a vaccination or whether they utilize influenza vaccination were classified into three domains: 'predisposing characteristics', 'enabling resources' and 'need'. Using multivariable logistic regression models odds ratios (OR) and corresponding 95% confidence intervals (95% CI) were calculated. RESULTS: As a combined result across three flu seasons, 368 of 1814 (20.3%) women received an influenza vaccination recommendation during pregnancy. Having had a high-risk pregnancy increased the odds of receiving a vaccination recommendation (OR = 1.3; 95% CI = 1.0-1.6; p = 0.045). In contrast, pregnancy onset in summer (OR = 0.7; 95% CI = 0.5-1.0; p = 0.027), autumn (OR = 0.4; 95% CI = 0.3-0.5; p < =0.001) or winter (OR = 0.5; 95% CI = 0.3-0.6; p < =0.001) (compared to spring) as well as mother's birthplace outside Germany (OR = 0.6; 95% CI = 0.4-0.9; p = 0.023) reduced the chance of getting a vaccination recommendation. Two hundred forty-two of one thousand eight hundred sixty-five (13%) women were vaccinated against influenza during pregnancy. Having received a vaccination recommendation was strongly associated with vaccination uptake (OR = 37.8; 95% CI = 25.5-55.9; p < =0.001). Higher health literacy status was also associated with a higher chance of vaccination uptake (OR = 1.7; 95% CI = 1.2-2.6; p = 0.008), whereas pregnancy onset in autumn (compared to spring) reduced the chance (OR = 0.5; 95% CI = 0.3-0.8; p = 0.008). CONCLUSIONS: At 13% the uptake rate of influenza vaccination is low. Having received a recommendation to vaccinate was strongly associated with uptake but only one fifth of all mothers report such a recommendation. Raising awareness in physicians regarding vaccinating during pregnancy seems to be of essential importance to increase vaccine uptake and to prevent influenza-related complications in pregnant women.

Determinants of maternal health four weeks after delivery: cross-sectional findings from the KUNO-kids health study.

BACKGROUND: The aim of this study was to examine the interaction of a multitude of socio-economic, lifestyle, environmental, psychosocial and birth related determinants and their effect on maternal health four weeks after delivery. METHODS: We used data from a German birth cohort study, the KUNO-Kids health study. Social determinants, as well as the self-rated maternal health and the physical and mental health status of mothers (indicated by means of the SF-12-questionnaire) were assessed through standardized questionnaires and personal interviews right after delivery and four weeks later. Linear regression models were calculated to determine the relationship between influencing factors and health outcomes. RESULTS: 1428 women were included in the analysis. Maternal self-rated health showed significant positive associations with breastfeeding (B (regression coefficient) 2.67; 0.86-4.48 (95% Confidence interval)) and estimating one's child as rather healthy (B 0.27; 0.19-0.34) and negative associations with social and emotional strains (B -3.50; -5.11- -1.88), obesity (B -2.56; -4.69- -0.42), having experienced a C-section (B -1.73; -3.23- -0.23), a positive history of somatic diseases (B -2.14; -3.53- -0.74), parental stress (B -0.39; -0.66- -0.11) and education of more than ten years (B -2.42; -3.95- -0.90). Maternal physical health status showed significant negative associations with age (B -0.13; -0.25- -0.01), employment before maternity leave (B -1.90; -3.59- -0.21), social and emotional strains (B -1.50; -2.67- -0.34), parental stress (B -0.28; -0.45- -0.12), C-section (B -4.06; -5.12- -2.99), having the first child (B -2.03; -3.09- -0.97) and a history of somatic diseases (B -2.00; -2.99- -1.01). Maternal mental health status showed significant positive associations with education of more than 10 years (B 2.27; 0.98-3.56) and a high level of social support (B 1.20; 0.06-2.34), while social and emotional strains (B -4.16; -5.48- -2.84) and parental stress (B -0.70; -0.92- -0.47) were negatively associated. CONCLUSIONS: We identified important protective factors for maternal health four weeks after delivery, such as a high level of social support. However, parental stress and social and emotional strains in particular seem to have a negative influence on maternal health. These findings have public health relevance.

Evaluation of Undescended Testes in Newborns: It Is Really Simple, Just Not Easy.

INTRODUCTION: The evaluation of the testicular position in newborns is important to ensure timely initiation of therapy. The aim of our study was to assess the reliability of a routinely performed screening examination. PATIENTS AND METHODS: Newborns were examined by a pediatrician between 48 and 72 h after birth. Boys with suspected cryptorchidism were double-checked by a pediatric urologist within 24 h. RESULTS: 1,181/2,353 children included in the study between June 2015 and December 2017 were male. Eight hundred sixty-one boys could be included in this analysis; 5.8% (n = 50) were diagnosed with undescended testis (UDT) by the pediatrician. 30/50 boys were double-checked at the Department of Pediatric Urology. Forty percent (20/50) were lost to follow-up. In 43% (13/30), the diagnosis could be confirmed. Three former studies had shown a relevant discrepancy in the results of the diagnosis of UDT made by health care providers and urologists/pediatric surgeons. To our knowledge, this is the first study evaluating the testicular position in male newborns in such a large prospective birth cohort study by physicians with ranging expertise within 1 day. CONCLUSION: Further treatment for UDT is based on clinical examination. Ours and previous studies can clearly show the various findings in boys suspected having UDT. Therefore, it is essential that the diagnosis is confirmed by a specialist before a therapy is initiated.

Parents' intention to get vaccinated and to have their child vaccinated against COVID-19: cross-sectional analyses using data from the KUNO-Kids health study.

A COVID-19 vaccine can be an important key for mitigating the spread of the pandemic, provided that it is accepted by a sufficient proportion of the population. This study investigated parents' intention to get vaccinated and to have one's child vaccinated against COVID-19. In May 2020, 612 parents participating with their child in the KUNO-Kids health study completed an online survey. Multivariable logistic regression models were calculated to analyze predictors of intention to vaccinate. Fifty-eight percent of parents intended to get vaccinated against COVID-19, and 51% intended to have their child vaccinated. Significant predictors for the intention to get vaccinated and for having the child vaccinated included stronger parental confidence in one's knowledge about prevention measures and lower beliefs that policy measures were exaggerated.Conclusion: COVID-19 vaccination hesitancy was considerable in our sample of parents in Germany. However, our study revealed some potentially modifiable factors which should be addressed by a comprehensive and tailored communication and education strategy. What is Known? • A COVID-19 vaccine can mitigate the spread of the pandemic. • Many parents are skeptical about vaccinations in general. What is New? • COVID-19 vaccination hesitancy was considerable in our sample of parents from Germany, not only for getting vaccinated but also for having the child vaccinated. • Negative parental attitudes regarding policy measures to contain the pandemic were associated with a lower intention to vaccinate.

Breastfeeding behavior is not associated with health literacy: evidence from the German KUNO-Kids birth cohort study.

PURPOSE: Despite the health benefits of full breastfeeding for both infants and mothers, less than 50% of mothers in Germany practice this method for at least 4 months after childbirth. Because of the growing importance of health literacy to improve public health, we investigated the role of maternal health literacy in breastfeeding behavior. METHODS: We analyzed the data of 1172 mother-child dyads of the KUNO-Kids health study of the University Children's and Maternity Hospital Regensburg. Maternal health literacy was assessed with the HLS-EU-Q47 questionnaire (sub-index health care) up to 48 h after childbirth. Outcome was analyzed 6 months after childbirth and categorized into full breastfeeding for less than 4 months or for at least 4 months. The association between breastfeeding and maternal health literacy was calculated with univariable and multivariable logistic regression analyses. RESULTS: 38.8% of mothers showed inadequate or limited health literacy. 75.9% of mothers had fully breastfed their child for at least 4 months. Univariable logistic regression analysis showed that health literacy and full breastfeeding for at least 4 months were not associated (OR = 0.995 [CI 0.977-1.015], p = 0.60). After adjusting for all potentially confounding variables with a significant association (p ≤ 0.05) on both health literacy and breastfeeding, the multivariable model showed no association between health literacy and breastfeeding (OR = 0.984 [CI 0.963-1.007], p = 0.170). CONCLUSION: Surprisingly, we found no association between health literacy and breastfeeding behavior in our study. Therefore, future research with comparable measurements of health literacy and breastfeeding is required to validate this result and to identify reasons for early breastfeeding cessation.

Peripartal anti-SARS-CoV-2-IgA/IgG in asymptomatic pregnant women during regional SARS-CoV-2-outbreak.

OBJECTIVES: The Severe Acute Respiratory Distress Corona Virus 2 (SARS-CoV-2) pandemic poses special challenges for the society and especially the medical staff. Even if a rather mild course is assumed among pregnant women the measures to prevent transmission of the infection are of outstanding importance. METHODS: To screen asymptomatic pregnant women during admission to our university maternal hospital we focused on anti-SARS-CoV-2-specific IgG and IgA antibody responses. Hundred and fifty one women admitted to the hospital for childbirth or caesarean delivery were included. In case of suspicious anti-SARS-CoV-2-antibody levels an RT-PCR was performed to confirm an ongoing infection with SARS-CoV-2. RESULTS: A total of 89% showed negative results for anti-SARS-CoV-2-IgA antibodies, whereas 3% were borderline and 7% positive (both labeled as suspicious). In only one patient with suspicious serology we detected SARS-CoV-2-RNA in the following RT-PCR. 2% presented anti-SARS-CoV-2-IgG antibodies, all being positive for anti-SARS-CoV-2-IgA. The observed positive rate of our study collective of 10.6% seemed much higher than the expected one (1.3%) based on the reports of the Robert Koch Institute and the specifications given by the test's manufacturer. The expected positive predictive value (PPV) was 4.3-6.7 times higher than the observed one. CONCLUSIONS: To our knowledge this is the first report of anti-SARS-CoV-2-antibody levels in the peripartum period of asymptomatic women. As the positive anti-SARS-CoV-2 serology poorly correlated with the confirmatory RT-PCR and the fact that mainly the detection of the virus by PCR correlates with the patient's infectiousness we suggest to rather perform a SARS-CoV-2-PCR-based admission screening in perinatal centers to prevent the spread of the disease.

Electrocardiographic Screening in the First Days of Life for Diagnosing Long QT Syndrome: Findings from a Birth Cohort Study in Germany.

INTRODUCTION: Newborn sudden infant death syndrome (SIDS) has failed to decrease in the last decades, and a third of the neonatal cases occurred within the first 6 days of life. The long QT syndrome (LQTS) is a genetic disease with a prevalence of 1 in 2,000 live births and contributes to almost 10% of SIDS cases. Early identification of LQTS through electrocardiogram (ECG) screening is likely to reduce mortality. METHODS AND RESULTS: In this ongoing prospective study we evaluated 2,251 ECGs from newborns participating in the KUNO Kids birth cohort study between July 2015 and July 2018. ECGs were recorded at a mean age of 2.0 days (IQR 0 days). The QT interval was corrected for heart rate using Bazett's formula (QTc). A QTc between 451 and 460, 461-470, and >470 ms was measured in 23 (1.0), 14 (0.6), and 62 (2.8%) participants, respectively. Fourteen neonates (0.62%) were admitted and monitored because their initial QTc was ≥500 ms. In 2 genetically analyzed participants, a mutation was found. One disease-causing for LQTS type 1 and the other of unclear significance. Cascade screening revealed affected members in both families. CONCLUSION: A standardized neonatal ECG screening in the first days of life is able to identify neonates with a relevant transient form of prolonged QT intervals and to aid diagnosing congenital LQTS.

Information on, knowledge and utilisation of support services during pregnancy and after childbirth: cross-sectional analyses of predictors using data from the KUNO-Kids health study.

OBJECTIVES: To investigate mothers' knowledge and utilisation of antenatal and perinatal support services as well as predictors of knowledge and service utilisation. DESIGN: Cross-sectional study. SETTING: Prospective birth cohort in Regensburg, Eastern Bavaria, Germany. PARTICIPANTS: 2455 mothers after delivery. OUTCOME MEASURES: Participants' knowledge of distinct antenatal and perinatal support services (poor vs good, defined by median split). Participants' use of antenatal services provided by midwife (yes, no) and of any other antenatal support services (yes, no). RESULTS: The vast majority of mothers knew at least some support services. Two-thirds of women (68.4%) reported to have used the services provided by midwives. 23.6% of women reported to have used at least one of the other antenatal services. Good knowledge of services was associated with higher education (OR 1.37, 95% CI 1.13 to 1.67), no migration background (OR 2.26, 95% CI 1.76 to 2.90), better health literacy (OR 1.04, 95% CI 1.03 to 1.06), while being primiparous (OR 0.72, 95% CI 0.60 to 0.86) and being unmarried/living with a partner (OR 0.71, 95% CI 0.57 to 0.89) reduced the chance. Predictors of service utilisation differed with regard to the services considered. CONCLUSIONS: Overall, mothers had a good level of knowledge of antenatal and perinatal support services. However, we found that some groups of women were less well informed. This inequality in social predictors of knowledge of services was also partly reflected in differences in service utilisation during pregnancy.

[Management of intra-abdominal dysgerminoma During pregnancy - A Case Report and Literature Review]. / Management Unterbauchraumforderungen in der Schwangerschaft ­ Fallbeschreibung eines extraovariell-intraabdominalen Dysgerminoms mit Überblick über die Literatur.

INTRODUCTION: Dysgerminomas are rare malignant germ cell tumors. They usually arise from the ovary, but case reports describing extraovarian dysgerminomas do exist. When treated adequately the disease has a good prognosis. Dysgerminomas diagnosed during pregnancy are very rare. METHODOLOGY: Report of extraovarian intra-abdominal dysgerminoma during pregnancy. Systematic literature review. CASE REPORT: A 35-year-old second gravida was diagnosed with a suspected intra-abdominal mass at 20 gestational weeks. During an exploratory laparotomy, a tumor infiltrating the transverse colon and histologically identified as a dysgerminoma was resected. Ovaries were clinically unremarkable. The induction of chemotherapy was postponed until after delivery. At 34 gestational weeks the patient underwent cesarean section and tumor debulking. Four cycles of bleomycin, etoposide and cisplatin were administered. After 12 months, cystic ovaries were found. Hysterectomy with bilateral adnexectomy was performed but no malignancy found. After 16 months, the patient was still in complete remission. CONCLUSION: We describe the first-ever published dysgerminoma in gravida primarily evolving intraabdominally and not affecting the ovaries. The decision for cytoreductive surgery, prolongation of pregnancy and postponing chemotherapy until after delivery combined the best benefit for the baby with a good maternal prognosis. Due to limited data regarding dysgerminomas in pregnancy, individual interdisciplinary concepts are mandatory.

Sociodemographic factors associated with health literacy in a large sample of mothers of newborn children: cross-sectional findings from the KUNO-Kids birth cohort study.

Health literacy is an important public health goal and of particular relevance when people are starting a family. Health literacy is thought to be crucial for the management of the manifold demands relating to child health which are imposed on parents. The aim of this study was to investigate health literacy in a large sample of mothers of newborn children in Germany. Sociodemographic factors and health literacy (as assessed by the HLS-EU health care scale) were analyzed using data from 2403 mothers of newborns who take part in an ongoing birth cohort study (KUNO-Kids health study). Almost 40% of mothers had a limited health literacy level. Being primiparous was significantly associated with lower health literacy, while having a high level of education compared with a medium level of education was significantly associated with higher health literacy.Conclusion: The finding of a substantial amount of mothers experiencing problems in dealing with and navigating through the healthcare system is important for the design of pediatric health services.What is Known:• New parents are confronted with many recommendations about child health.• Health literacy of parents is considered crucial for child health outcomes.What is New:• Many mothers of newborns have a limited health literacy level.• First-time mothers and mothers with lower education are particularly at risk for low health literacy.

Joining to promote young talents: an experience report from the first German Summer School for Obstetrics and Gynaecology for medical students.

PURPOSE: The Commission for the Promotion of Young Talents of the German Society for Gynaecology and Obstetrics e.V. was founded in 2017, aiming to inspire medical students for a career in obstetrics and gynaecology by developing a concept for the first German Summer School in this field. Here, medical students shall be introduced to this multifaceted specialty and have their interest in it kindled. METHODS: This article reports about the experiences of the first gynaecological summer school which was held at the University Hospital Heidelberg for 2 days in August 2018. The programme included keynote presentations, discussion roundtables and skills-lab training. To assess students' related satisfaction, and to improve future projects, an evaluation survey with seven items and two open-comment questions was given to each participant after the event. RESULTS: Mostly female students [n (♀) = 37, 93%; n (♂) = 3, 7%] from 15 different medical universities from all over Germany participated. Available places were booked within 1 week. Participants were in their clinical part of their studies between the 5th and 16th semester. The average rating of the event was excellent with 1.1 points (1 = best-5 = worst), while the selection of topics scored lowest marks with an average rating of 1.7 points. CONCLUSION: Due to the great success, the high demand and the student's positive evaluation, annual summer schools in obstetrics and gynaecology are planned. Because most of the participating students have shown a high interest and have appropriate education in the domain, the information content of keynote presentations could be increased above basic level in future projects.

A model for estimating the lifelong exposure to PM2.5 and NO2 and the application to population studies.

Numerous epidemiological studies have confirmed the negative influences of air pollutants on human health, where fine particles (PM2.5) and nitrogen dioxide (NO2) cause the highest health risks. However, the traditional studies have only involved the ambient concentration for a short to medium time period, which ignores the influence of indoor sources, the individual time-activity pattern, and the fact that the health status is impacted by the long-term accumulated exposure. The aim of this paper is to develop a methodology to simulate the lifelong exposure (rather than outdoor concentration) to PM2.5 and NO2 for individuals in Europe. This method is realized by developing a probabilistic model that integrates an outdoor air quality model, a model estimating indoor air pollution, an exposure model, and a life course trajectory model for predicting retrospectively the employment status. This approach has been applied to samples of two population studies in the frame of the European Commission FP7-ENVIRONMENT research project HEALS (Health and Environment-wide Associations based on Large Population Surveys), where socioeconomic data of the participants have been collected. Results show that the simulated exposures to both pollutants for the samples are influenced by socio-demographic characteristics, including age, gender, residential location, employment status and smoking habits. Both outdoor concentrations and indoor sources play an important role in the total exposure. Moreover, large variances have been observed among countries and cities. The application of this methodology provides valuable insights for the exposure modelling, as well as important input data for exploring the correlation between exposure and health impacts.

Effect of betamethasone, indomethacin and fenoterol on neonatal and maternal mononuclear cells stimulated with Escherichia coli.

Despite considerable progress in the field of perinatal care, infectious diseases, especially when caused by gram negative bacteria, remain a major reason for neonatal morbidity and mortality. Notably infants born prematurely and those with very low birth weight are at risk due to their immature and deficient immune system and their prolonged hospitalization which promotes nosocomial infections. In case of impending preterm birth, betamethasone is given to induce lung maturation and tocolytic agents like indomethacin or fenoterol are administered to suppress premature labor. The aim of this study was to analyze the effects of these drugs on the immune system of mothers and neonates. Therefore, mononuclear cells from cord blood and peripheral maternal blood were stimulated with Escherichia coli and incubated with betamethasone, indomethacin and fenoterol. Subsequently the effect of the treatment on cytokine production was determined. Betamethasone alone and in combination with tocolytic agents inhibited the production of pro- and anti-inflammatory cytokines. Not only does betamethasone dampen the immune response by reducing the production of cytokines, it also has a variety of other detrimental short- and long-term effects on the neonate. In conclusion we would recommend using biological markers to determine if premature labor actually leads to preterm birth and subsequently administer betamethasone only to mothers giving birth prematurely.

KUNO-Kids birth cohort study: rationale, design, and cohort description.

BACKGROUND: Birth cohort studies can contribute substantially to the understanding of health and disease - in childhood and over the life course. The KUNO-Kids birth cohort study was established to investigate various aspects of child health, using novel omics technologies in a systems medicine approach. RESULTS: After 3 years of recruitment, 2515 infants and their families have joined the study. Parents with higher education are overrepresented as in many other birth cohorts and are more likely to complete follow-up assessments via self-report questionnaires. The vast majority of participants consented to clinical examinations of their child and to the non-invasive collection of diverse biosamples, which were processed specifically for their integrated use in omics technology covering genomics, epigenomics, transcriptomics, metabolomics, and microbiome analyses of the skin, oral cavity, and stool. CONCLUSIONS: The data and diverse biomaterial collected in the KUNO-Kids birth cohort study will provide extensive opportunities for investigating child health and its determinants in a holistic approach. The combination of a broad range of research questions in one study will allow for a cost-effective use of biomaterial and omics results and for a comprehensive analysis of biological and social determinants of health and disease. Aiming for low attrition and ensuring participants' long-term commitment will be crucial to fully exploit the potential of the study.
