Abstract
Smoking during pregnancy is one of the leading causes for adverse pregnancy outcomes. We studied parental smoking both before and during pregnancy in a retrospective cohort of 21 472 singleton pregnancies. Although most smoking women (74%) ceased tobacco use, there was possible gestational exposure to maternal cigarette smoking in every fifth pregnancy. Continued smoking throughout pregnancy was more prevalent in the partners (22%) than in the pregnant women (7%). The smoking behaviour of the women, especially the number of cigarettes smoked per day (CPD), before and in early pregnancy predicted the continuation of smoking throughout the pregnancy and could be used in identifying high risk groups. In addition, their partner's smoking habits both before and during pregnancy, were associated with the likelihood that the woman would continue to smoke during her pregnancy (rs ≈ 0.4). Furthermore, continued smoking of both parents were associated with decreased birth weight, head circumference and Apgar score, and increased duration of hospital stay and need for special care after birth. Consequently, addressing the lifestyles of both parents in the health care and maternity clinics could help in reducing maternal cigarette smoking during pregnancy and the adverse pregnancy outcomes associated with smoking.

Abstract
AIM To evaluate umbilical arterial lactate concentrations after spontaneous vaginal delivery and after elective Cesarean delivery, and to study the simultaneous effects of maternal and obstetric variables in high lactate levels in vaginally delivered healthy term singletons. METHODS The birth register study included information about the umbilical artery lactate values and clinical perinatal data from 7723 women and their singleton newborns (7301 spontaneous vaginal and 422 elective cesareans) from Kuopio University Hospital, Finland. High lactate levels were evaluated more extensively among healthy term neonates (N = 6541), to evaluate high levels after normal vaginal labors. RESULTS The mean lactate level was significantly lower after elective cesarean compared to vaginal delivery (2.42 [0.94] vs. 3.56 [1.62] mmol/l; p < 0.0001). Consequently, the 90th percentile limit values were 3.60 and 5.80 mmol/L. Among healthy term newborns born vaginally, higher lactate values (≥5.80 mmol/L) were independently associated with a longer duration of the active second stage of labor (ORs 1.91-10.97) and duration of ruptured fetal membranes (ORs 1.36-2.46), higher gestational age at birth (ORs 1.41-1.86), null parity (OR 2.17), maternal infection (OR 1.81) and short maternal stature (OR 1.45). We report 90th/95th limits for umbilical arterial lactate values in relation to the various durations of labors for term newborns who are delivered by the vaginal route. CONCLUSIONS Even though the high umbilical lactate levels may indicate serious birth asphyxia, levels after vaginal birth reflect the physiological stress and subclinical transient asphyxia frequently seen in normal vaginal deliveries.

Abstract
BACKGROUND Several recent studies have investigated the association between maternal diet during pregnancy and wheezing or asthma in children. However, whether a specific dietary pattern during pregnancy protects children from wheezing or atopic diseases remains unclear. This study investigated the association between The Alternative Healthy Eating Index for Pregnancy (AHEI-P), the Dietary Inflammatory Index (DII), and the risk for wheezing and atopic eczema in children during the first year of life. METHODS This study included 1330 mother-child pairs who attended the Kuopio Birth Cohort (KuBiCo) study and had dietary information during the last trimester and information on children's health in the first year of life. AHEI-P and DII indicate a healthy diet and dietary inflammation potential during pregnancy. The AHEI-P and DII were compared with reported wheezing and doctor-diagnosed atopic eczema in children during the first year of life. RESULTS Neither AHEI-P nor DII is associated with wheezing or atopic eczema in children when analyzed by continuous variables and by tertiles. The odds ratio (95% CI) for AHEI-P and wheezing was 0.99 (0.98-1.01), for AHEI-P and atopic eczema1.01 (0.99-1.02), for DII and wheezing 1.02 (0.95-1.09), and for DII and atopic eczema 0.97 (0.91-1.04). CONCLUSION In this cohort study, AHEI-P and DII during pregnancy were not associated with wheezing or atopic eczema in the offspring during the first year of life.

Abstract
AIMS Coffee intake is associated with a decreased risk of type 2 diabetes among non-pregnant people. We aimed to investigate the association between caffeine, coffee and cola drink intake in early pregnancy and the risk of gestational diabetes (GDM). METHODS Kuopio Birth Cohort (KuBiCo) is a prospective cohort study including pregnant women who were followed at the prenatal clinics in outpatient healthcare centers and gave birth in Kuopio University Hospital, Finland (n=2214). Maternal diet during the first trimester of pregnancy was assessed using a 160-item food frequency questionnaire. GDM was diagnosed by oral glucose tolerance test according to the Finnish national guidelines mainly between 24 and 28 gestational weeks. RESULTS Women with moderate coffee intake in the first trimester were less likely diagnosed with GDM than women without coffee intake in an age-adjusted model (OR 0.87; 95% CI 0.76-0.99; p = 0.03), but the association was attenuated in multi-adjusted models (p = 0.11). No association was found between caffeine intake and GDM. One third (32.4%) of pregnant women consumed caffeine over the recommendation (> 200 mg/d). Women who consumed cola drinks more than the median (33.3 mL/d) had an increased risk of GDM (OR 1.29; 95% CI 1.02-1.63, p = 0.037) in multi-adjusted model compared to those who consumed less. CONCLUSIONS Caffeine intake during the first trimester of pregnancy was not associated with the risk of GDM but a minor non-significant decrease was seen with moderate coffee intake. Although the average consumption of cola drinks was low in the KuBiCo cohort, higher consumption was associated with an increased risk of GDM. Further studies are needed to evaluate the safe amount of coffee during pregnancy, since the recommended caffeine intake was exceeded in almost half of the coffee drinkers.

Abstract
BACKGROUND Delayed cord clamping (DCC) is recommended for preterm and term neonates, regardless of delivery mode. After impression of increased maternal blood loss following DCC implementation during Cesarean delivery (CD) concerns arose about maternal safety, particularly in term CDs. MATERIALS AND METHODS We conducted a retrospective cohort study by reviewing birth records from our tertiary hospital in Kuopio, Finland including 914 women with singleton term CD and recorded estimated blood loss. Early cord clamping (ECC) occurred from January 2016 to December 2019, while DCC (30-60 s) from January 2020 to December 2020. We evaluated maternal and neonatal outcomes for ECC vs. DCC and assessed severe postpartum hemorrhage (PPH) (≥1500 ml) and its potential clinical risk factors. RESULTS In total, 914 women were included (DCC N = 152; ECC N = 762). Estimated mean maternal blood loss showed no significant difference between DCC and ECC groups (697 ml vs. 750 ml, p < 0.96). Severe PPH was less frequent in the DCC group (4.6% vs. 10.5 %, p < 0.024). Neonatal outcomes were similar between groups. Multivariable analysis revealed that women with placenta previa (OR 5.63, p < 0.001), macrosomic neonate (OR 2.75, p < 0.001), and intrapartum infection (OR 2.00, p < 0.057) had an increased risk for severe PPH. Earlier CD was associated with less severe PPH (OR 0.36, p < 0.001). CONCLUSIONS DCC (30-60 s) during term CD did not increase maternal blood loss in singleton pregnancies and demonstrated no short-term adverse effects on neonates. Our findings support the general practice of DCC during both elective and nonelective term CD.

Abstract
PURPOSE To survey trends of antipsychotic use during pregnancy and examine the associations between the use of quetiapine or any antipsychotic and adverse obstetric and neonatal outcomes. METHODS Birth register study of 36,083 women who gave birth at Kuopio University Hospital, Finland, between 2002 and 2016. Obstetric and neonatal outcomes between women using quetiapine (N = 152) or any antipsychotic (N = 227) were compared to controls (N = 35,133). RESULTS Altogether 246 (0.7%) women used antipsychotic medications during pregnancy and 153 (62,2%) of these women used quetiapine. Antipsychotic usage increased from 0.4% to 1.0% during the 15-year follow-up. Women using antipsychotics were more likely to smoke, drink alcohol, use illicit drugs, use other psychotropic medications, and have higher pre-pregnancy body mass index. Quetiapine use was associated with higher risk of increased postpartum bleeding in vaginal delivery (aOR 1.65; 95%CI 1.13-2.42), prolonged neonatal hospitalization (≥5 days) (aOR 1.54; 95%CI 1.10-2.15), and higher placental to birth weight ratio (PBW ratio) (aB 0.009; 95%CI 0.002-0.016). Use of any antipsychotic was associated with a higher risk of gestational diabetes mellitus (aOR 1.64; 95%CI 1.19-2.27), increased postpartum bleeding in vaginal delivery (aOR 1.50; 95%CI 1.09-2.07), prolonged neonatal hospitalization (≥5 days) (aOR 2.07; 95%CI 1.57-2.73), and higher PBW ratio (aB 0.007; 95%CI 0.001-0.012). CONCLUSION The use of antipsychotic medications increased among Finnish pregnant women from 2002 to 2016. Pregnant women using antipsychotics appear to have a higher risk for some adverse pregnancy and birth outcomes and may benefit from more frequent maternity care follow-ups.

Abstract
PURPOSE To study whether different hormonal phases affect appetite regulation, food intake, and concentrations of leptin, glucagon-like peptide-1 (GLP-1), and high-sensitivity C-reactive protein (hs-CRP) during a long agonist in vitro fertilization (IVF) protocol. METHODS Fifty-four infertile women were encountered thrice, the first of which was at the beginning of their period (low estradiol). The other two visits were during a gonadotrophin-releasing hormone (GnRH) analog downregulation (low estradiol) and at the end of a follicle-stimulating hormone (FSH) stimulation (high estradiol). The first visit was the reference; the women served as their controls. The concentrations of leptin, GLP-1, and hs-CRP were assessed from plasma. Dietary intake was assessed using food records (FRs). In addition, weight, height, body mass index (BMI), and plasma levels of estradiol, glucose, HbA1c, insulin, and lipids were monitored. Twenty-six of the subjects also had a postprandial test. RESULTS During the stimulation protocol, leptin concentrations elevated (P < 0.001), and energy intake decreased (P = 0.03), while estradiol levels increased (P < 0.001). GLP-1 levels unchanged (P = 0.75) and hs-CRP (P = 0.03) concentrations diminished, while estradiol levels increased. CONCLUSION No increased food intake or weight gain occurred during the stimulation protocol; thus, leptin may protect from overeating during high estradiol levels, and leptin resistance may not occur during a short follow-up. Also, a favorable anti-inflammatory effect was detected. During this study, we observed no harmful metabolic effects, which might affect negatively maternal health.

Abstract
Previous steroid hormone studies concerning pregnancy and newborns have mainly focused on glucocorticoids; wider steroid profiles have been less commonly investigated. Here, we performed a comparative analysis of 17 steroids from newborn hair and umbilical cord serum at the time of delivery. The study participants (n = 42, 50% girls) were a part of the Kuopio Birth Cohort and represent usual Finnish pregnancies. The hair and cord serum samples were analyzed with liquid chromatography high resolution mass spectrometry and triple quadrupole tandem mass spectrometry, respectively. We detected high individual variations in steroid hormone concentrations in both sample matrices. The concentrations of cortisol (F), corticosterone (B), estrone (E1), estradiol (E2), dehydroepiandrosterone (DHEA), 11β-hydroxyandostenedione (11bOHA4), 5α-androstanedione (DHA4), and 17α-hydroxypregnenolone (17OHP5) correlated positively between cord serum and newborn hair samples. In addition, F and 11bOHA4 concentrations correlated positively with each other in both newborn hair and cord serum samples. The cortisone-to-cortisol ratio (E/F) was significantly higher in cord serum than in newborn hair samples reflecting high placental 11βHSD2 enzyme activity. Only minor sex differences in steroid concentrations were observed; higher testosterone (T) and 11-deoxycortisol (S) with lower 11bOHA4 in male cord serum, and higher DHEA, androstenedione (A4) and 11bOHA4 in female newborn hair samples. Parity and delivery mode were the most significant pregnancy- and birth-related parameters associating with F and some other adrenocortical steroid concentrations. This study provides novel information about intrauterine steroid metabolism in late pregnancy and typical concentration ranges for several newborn hair steroids, including also 11-oxygenated androgens.

Abstract
BACKGROUND Urban-related nature exposures are suggested to contribute to the rising prevalence of allergic diseases despite little supporting evidence. Our aim was to evaluate the impact of 12 land cover classes and two greenness indices around homes at birth on the development of doctor-diagnosed eczema by the age of 2 years, and the influence of birth season. METHODS Data from 5085 children were obtained from six Finnish birth cohorts. Exposures were provided by the Coordination of Information on the Environment in three predefined grid sizes. Adjusted logistic regression was run in each cohort, and pooled effects across cohorts were estimated using fixed or random effect meta-analyses. RESULTS In meta-analyses, neither greenness indices (NDVI or VCDI, 250 m × 250 m grid size) nor residential or industrial/commercial areas were associated with eczema by age of 2 years. Coniferous forest (adjusted odds ratio 1.19; 95% confidence interval 1.01-1.39 for the middle and 1.16; 0.98-1.28 for the highest vs. lowest tertile) and mixed forest (1.21; 1.02-1.42 middle vs. lowest tertile) were associated with elevated eczema risk. Higher coverage with agricultural areas tended to associate with elevated eczema risk (1.20; 0.98-1.48 vs. none). In contrast, transport infrastructure was inversely associated with eczema (0.77; 0.65-0.91 highest vs. lowest tertile). CONCLUSION Greenness around the home during early childhood does not seem to protect from eczema. In contrast, nearby coniferous and mixed forests may increase eczema risk, as well as being born in spring close to forest or high-green areas.

Abstract
BACKGROUND The primary aim was to evaluate the association between gestational diabetes and blood glucose levels and vulvovaginal yeast infections in pregnancy. Secondly, we clarified the possible associations between maternal and prenatal factors, and birth outcomes and yeast infections. METHODS Three thousand nine hundred sixty-five pregnant women of the Kuopio Birth Cohort Study (KuBiCo) reported vulvovaginal yeast infections during pregnancy, via electronic questionnaires. Maternal and prenatal data, as well as clinical obstetric and early neonatal outcomes were registered during and after birth. The oral glucose tolerance test was performed on 3,079 women during pregnancy. Logistic regression analysis evaluated the possible multivariable associations between yeast infections, gestational diabetes and other prenatal and maternal factors. RESULTS No association was detected between gestational diabetes or blood glucose levels and vulvovaginal yeast infections during pregnancy. In multivariable analysis, women with yeast infections were more often multiparous, with higher education and had used more often antibiotics during pregnancy compared to others. No significant associations were detected in multivariable analysis between infections, the mode of delivery, preterm birth, birth weight or Apgar scores. CONCLUSIONS Women with reported vulvovaginal yeast infections managed generally well during pregnancy. They had no more gestational diabetes or higher blood glucose levels and their newborns managed equally well during early neonatal period.

Abstract
BACKGROUND Depression and diet quality appear to be associated in the general population. Nevertheless, little is known about their relationship among pregnant females. OBJECTIVE The aims of this study were first, to investigate longitudinally whether or not diet quality is associated with depressive symptoms during pregnancy; second, to examine whether or not variation in diet quality during pregnancy predicts variation in depressive symptoms; and third, to explore how individual dietary components are associated with depressive symptoms. DESIGN A longitudinal secondary analysis of the Kuopio Birth Cohort Study in eastern Finland was conducted. Data were collected from pregnant females during the first and third trimesters of pregnancy. PARTICIPANTS/SETTING The participants were 1,362 pregnant females who entered the study between 2012 and 2017. MAIN OUTCOME MEASURES Depressive symptoms, as measured with the Edinburgh Postnatal Depressive Scale during the first and third trimesters of pregnancy were used as continuous variables. STATISTICAL ANALYSES PERFORMED The main analyses consisted of linear mixed model analyses adjusted for potential confounders to longitudinally assess the association between diet quality as measured by the Healthy Eating Index-2015, calculated using data from a food frequency questionnaire completed during the first trimester and third trimester, and depressive symptoms during the study period. An exploratory set of linear mixed models was also used to longitudinally assess the associations between selected individual food frequency questionnaire food groups and depressive symptoms. RESULTS Descriptive analyses revealed that 12.3% of the participants had clinically relevant levels of depressive symptoms (ie, Edinburgh Postnatal Depressive Scale score ≥10) during either the first or third trimester. Longitudinal modeling suggested that depressive symptoms in pregnant females tend to remain stable throughout pregnancy. Females with a poorer quality diet already displayed higher levels of depressive symptoms during the first trimester of pregnancy (β = -.038 ± .016; P = 0.022). Variation in diet quality did not predict variation in depressive symptoms over the course of pregnancy (β = -9.741 × 10-5 ± .001; P = 0.869). CONCLUSIONS Females entering pregnancy with a poorer quality diet also displayed higher levels of depressive symptoms compared with females with a higher quality diet at the beginning of pregnancy, and this association remained constant throughout pregnancy. Further research is needed to assess the direction and the potential causality of the observed associations between diet quality and depressive symptoms.

Abstract
INTRODUCTION Selective serotonin reuptake inhibitors (SSRIs) are commonly used medication for the treatment of depression during pregnancy. Their use may affect various biological molecules such as enzymes which regulate placental hormonal production and xenobiotic metabolism. Our aim was to investigate the effect of maternal SSRI use on activities of three placental enzymes. METHODS We analyzed activities of xenobiotic metabolism enzymes cytochrome P450 1A1 (CYP1A1), aromatase (CYP19A1), and glutathione-S-transferase (GST) from placental microsomal and cytosolic subcellular fractions. Term placentas were collected from 47 SSRI users and 49 control women participating Kuopio Birth cohort (KuBiCo) during the years 2013-2015. Among SSRI users, escitalopram was the most widely used SSRI medication. RESULTS The mean enzyme activities of all studied enzymes were lower in SSRI users compared to controls. A statistically significant difference was observed in the enzyme activities of CYP19A1 (p = 0.001) and CYP1A1 (p = 0.002) between the study groups after adjusting for use of additional medication, gestational diabetes, sex of the newborn and gestational weeks at delivery. SSRI use had no significant effect on placental GST enzyme activity. DISCUSSION Our results indicate that SSRI medication alters placental enzyme activities. This may lead disturbances in maternal steroid hormone balance as well as in xenobiotic metabolism and may provide risk for both developing fetus and pregnant women.

Abstract
Background The partners’ role in determining the alcohol consumption behavior of pregnant women is not well studied. We measured alcohol use before and during pregnancy in pregnant women and their partners to evaluate the correlation in their levels of consumption. Methods We evaluated the self‐reported alcohol use of 14,822 women and their partners during 21,472 singleton pregnancies delivered in Kuopio University Hospital, Finland during the period 2009‒2018. The information was gathered during pregnancy and at the time of childbirth and recorded in two databases that were merged to yield a single cohort. Missing data were accounted for by multiple imputation using the predictive mean matching method. Results In 86% of the pregnancies, women reported alcohol use before pregnancy, whereas in 4.5% of the pregnancies women reported alcohol use during pregnancy. In contrast, no decrease was detected in their partners’ alcohol use before or during pregnancy. In 26% of the pregnancies, the woman reported stopping alcohol use only after recognizing that she was pregnant. Before pregnancy, there were strong correlations between the pregnant women and their partners in the total Alcohol Use Disorders Identification Test score (rs = 0.69, p < 0.0001) and the self‐reported average weekly amount of alcohol consumed (rs = 0.56, p < 0.0001). During pregnancy, there were weak correlations between the pregnant women and their partners in the frequency of drinking (rs = 0.20, p < 0.0001) and the average weekly amount of alcohol consumed (rs = 0.18, p < 0.0001). Conclusions The self‐reported alcohol consumption of pregnant women and their partners was positively correlated both before and during pregnancy, though the correlation declined substantially during pregnancy. Evaluating the alcohol consumption of both parents before pregnancy could assist in identifying women at risk of prenatal alcohol exposure. Supporting a reduction in partners' alcohol use could help to reduce pregnant women's alcohol consumption and prevent its associated harms.

Abstract
Objective To examine whether perinatal factors are associated with low-grade inflammation measured by high-sensitivity C-reactive protein levels during adolescence. Methods Nested case-control study of 125 teenagers who were born by Cesarean delivery and had high-sensitivity C-reactive protein levels determined at 15–17 years. Data on obstetric and perinatal factors were recorded prospectively at the time of their birth. Results Median values of high-sensitivity C-reactive protein were significantly higher in teenagers, who were born as large for gestational age or with maternal diabetes compared to others (2.54 vs 0.34 mg/L; p < 0.024), and born during spring or summer compared to those born during winter or autumn (0.48 vs 0.27 mg/L; p < 0.023). No other perinatal associations were detected (for ex. such as electivity of operation, onset of labor, rupture of fetal membranes, cervical dilatation at delivery, gestational age, Apgar scores at 5 min, umbilical blood pH value, administration of neonatal antibiotics or need of neonatal intensive care treatment) in CRP levels. Further, teenagers with current body mass index in the highest tertile, regular medication for chronic disease and girls using oral contraceptives had significantly higher high-sensitivity C-reactive protein levels than others. Conclusion Prenatal exposures such as maternal metabolic environment and seasonality may have longterm effects on the low-grade inflammation and later cardiometabolic risks. Seasonality might be partly explained by maternal vitamin D levels during pregnancy, and thus future efforts are warranted to ensure sufficient vitamin D availability during pregnancy. Surprisingly, no other significant associations were detected between perinatal characteristics and high-sensitivity C-reactive protein levels.

Abstract
We examined possible changes in endothelial function during a long agonist in vitro fertilization (IVF) protocol. We measured flow-mediated dilatation (FMD) and FMD percent (FMD%) from the brachial artery and plasma levels of high-sensitivity C-reactive protein (hsCRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-〈). We studied longitudinally three time points in 27 women undergoing a long agonist IVF treatment at Kuopio University Hospital. The first visit was at the beginning of their period (low estradiol). The other two visits were during gonadotrophin-releasing hormone (GnRH) analog downregulation (low estradiol) and at the end of follicle-stimulating hormone (FSH) stimulation (high estradiol). The first visit was used as the reference, and the women served as their own controls. During the stimulation protocol, FMD and FMD% remained. Toward the end of stimulation, hsCRP (P = 0.003), IL-6 (P = 0.04), and TNF-〈 (P = 0.008) concentrations all decreased, while estradiol levels increased (P < 0.001). Correlations between estradiol and proinflammatory factors or FMD were, however, non-significant. The only significant correlation appeared between FMD% and hsCRP at Visit 2 (r = 0.485, P = 0.01). In conclusion, IVF stimulation promoted no change in endothelial function, whereas hsCRP, IL-6, and TNF-〈 decreased. These findings indicate that estrogen may improve the cytokine profile among healthy women undergoing IVF, but this is not reflected in endothelial function.

Abstract
OBJECTIVE This study aimed to compare outcomes of mini-invasive surgical treatment of endometriosis, especially conventional laparoscopy with robotic-assisted laparoscopy, and to evaluate the quality of life. METHODS One hundred three consecutive patients with endometriosis who had surgery from 2014 to 2017 owing to an indication of pain were enrolled in this retrospective study. The majority (n = 77, 75%) of patients underwent conventional laparoscopy and 18 (17%) had robotic-assisted laparoscopy. The quality of life was postoperatively assessed with a questionnaire. RESULTS The rates of parametrectomy (76% vs. 45%,) and rectovaginal resection (28% vs. 4%) were significantly higher in robotic-assisted laparoscopy than in laparoscopy. Additionally, the rate of bowel operations (50% vs. 17%), especially the shaving technique, was higher in robotic-assisted laparoscopy surgery than in laparoscopy (39% vs. 8%). There was no difference in the rate of postoperative complications between laparoscopy and robotic-assisted laparoscopy. Most (91%) of the patients who answered the questionnaire felt that surgical treatment had relieved their pain. In the laparoscopic and robotic-assisted groups, 88% of respondents felt that their quality of life had improved after surgery. CONCLUSIONS This study suggests that robotic-assisted laparoscopy is a feasible method to resect deep infiltrating endometriosis, especially in the rectosigmoid area.

Abstract
AIM To evaluate the association between lactate concentrations in fetal blood samples and the different advanced labour stages. METHODS Eighteen-month prospective population-based clinical study of 187 singleton pregnant women in labour who were monitored by fetal blood sampling (FBS) because of non-reassuring intrapartum CTG results at Kuopio University Hospital, Finland. Peripheral lactate concentration and pH were analysed at different stages of labour and in umbilical arterial samples immediately after delivery. RESULTS FBS samples (N = 350) were obtained from 5.4 % of all women in labour during the study period, and 48 % had spontaneous delivery, 27 % had vacuum-assisted vaginal delivery, and 25 % had nonelective Caesarean delivery. FBS lactate levels increased 4-11% with every 1-2 cm of cervical dilation and 18 % from early labour to fully dilated cervix. In 42 women with at least two FBSs, lactate levels increased significantly from the early I stage of labour and up to a fully dilated cervix. Lactate values were significantly higher in umbilical arterial samples compared to FBSs. Sensitivity of the highest FBS lactate values for the detection of birth asphyxia were considerably low varying between 42.9-57.1%. CONCLUSION FBS lactate levels were related to the stage of labour during vaginal delivery attempt. Wide range of lactate levels during labour complicates its use as a predictor of birth asphyxia.

Abstract
The infants of mothers with elevated depressive symptoms (EDS) postpartum appear to be at increased risk of somatic health problems during their first 12 months of life in low- and lower-middle-income countries. However, in higher-income countries, knowledge of this association is scarce. We sought to examine whether maternal reports of infant health problems, adherence to vaccination schedules and analgesic supply to the infant during the first 12 months of life differ between mothers with and without postpartum EDS. Altogether, 969 women who were enrolled in the Kuopio Birth Cohort study (www.kubico.fi) during 2012-2017 were included in this investigation. Depressive symptoms were measured with the Edinburgh Postnatal Depression Scale during pregnancy (1st and/or 3rd trimester) and at eight weeks postpartum. Infant health data were collected as a part of a 12-month online follow-up questionnaire for mothers and were based on self-reports of either maternal observations or physician-determined diagnoses. Postpartum EDS were associated with a 2- to 5-fold increased likelihood of abnormal crying and paroxysmal wheezing (based on parental observations), as well as gastroesophageal reflux and food allergy (based on physician-determined diagnoses). Mothers with postpartum EDS also supplied their infants with analgesic medication for longer periods. Adherence to vaccination schedules was similar between the examined groups. In conclusion, infants of mothers with postpartum EDS may be more likely to experience health problems or to be perceived by their mother as having health problems, and thus receive more medications.

Abstract
Background The maternal use of paracetamol during pregnancy has been associated with the development of preeclampsia. This study aims to clarify whether the connection is causal or whether it is due to reverse causation. Methods This study is a continuation of the retrospective case cohort study examining 2,508 pregnant women using a variety of drugs and the development of preeclampsia (1,252 women with preeclampsia and 1,256 controls). For the purposes of this study, more precise data was collected from several hospital databases of the women among this cohort who had reported taking paracetamol during pregnancy (indications, gestational period etc.); this was evaluated in association with the development of preeclampsia. Results 5.5% (100 cases and 37 controls) of all the study population (2,508) had clearly reported paracetamol use. Women with preeclampsia had used significantly more often paracetamol during pregnancy compared to controls (cases 8.0%, controls 2.9%, p < 0.001). The difference was most evident in the third trimester (after the 29th GW) and the use of paracetamol was associated with both mild and severe preeclampsia. Headache and “general pain” were the most common indications for medication among all paracetamol users. Conclusions The use of paracetamol in the third trimester of pregnancy was associated with preeclampsia. This observation indicates that association between paracetamol use and preeclampsia is probably due to reverse causation, i.e. women with preeclampsia experience more headaches due to preeclampsia symptoms since this association was not detected with the use of paracetamol in earlier stages of pregnancy.

Abstract
BACKGROUND/AIM Examine features of blood and lymphatic vessels in ovarian tumors and their significance to prognosis of ovarian cancer. PATIENTS AND METHODS A total of 139 women with epithelial ovarian tumors were included: 86 malignant, 17 borderline and 36 benign. Density, percentage, mean size and number of blood microvessels in tumors were measured by immunohistochemistry with antibodies against CD34 and CD105. Lymphatic vessel density was assayed using the D2-40 antibody against podoplanin. RESULTS Angiogenesis was most profuse in malignant tumors. Small size of lymph vessels predicted 26% shorter 5-year survival of ovarian cancer patients. Further, high percentage of lymphatic vessels in tumors was associated with lymph node metastasis, and high density with cancer recurrence. Lower number of microvessels, as assessed by CD34 staining, predicted shorter progression-free survival. Additionally, the large size of microvessels assessed by CD34 and the high number of vessels assessed by CD105 were related to residual tumor >1 cm at primary surgery and also, large vessel size was associated with stage III, as assessed by CD105 staining. CONCLUSION CD34 and CD105 define different characteristics of microvessels. Parameters of lymph vessels may predict the prognosis of ovarian cancer.

Abstract
OBJECTIVE To evaluate the causes behind the association between hypothyroidism and the risk of preeclampsia. METHODS Checking of individual hospital and birth records from 149 levothyroxine users among 2,508 women in the preeclampsia case-control study (2002-2016). RESULTS There were significant association between levothyroxine medication and preeclampsia (OR 1.48, 95th CI 1.06-2.07; p ≤ 0.022). The presence of comorbid diseases was associated with a significantly higher risk for the development of preeclampsia in women using levothyroxine. CONCLUSION Levothyroxine use during pregnancy was associated with 1.5-times higher risk for preeclampsia, but it is also linked to the other comorbid risk factors.

Abstract
BACKGROUND This study was made to figure out, does low and high estradiol levels during in vitro fertilization (IVF) cycles have a different effect on carotid artery distensibility (Cdis), carotid artery diameter (Cdia), blood pressure and metabolic factors? Can the stimulation protocol be considered safe to women's vasculature? METHODS We studied 28 women having a long agonist protocol IVF-treatment in Kuopio University Hospital during the years 2011-2016. Patients were examined at three time points: in the beginning of their own period (low estradiol), during the gonadotrophin releasing hormone (GnRH) analogue downregulation (low estradiol) and during the follicle stimulating hormone (FSH) stimulation (high estradiol). Women served as their own controls and their menstrual phase (2- to 5-day period after the beginning of menstruation with low estrogen) was used as the reference. Cdis and Cdia were assessed using ultrasound. Blood pressure, weight, estradiol levels and lipids were monitored. RESULTS Cdis, Cdia, systolic and diastolic blood pressures peaked during the GnRH-analogue treatment with the lowest estradiol levels. Cdis, Cdia and systolic blood pressures declined by 11% (P = 0.002), 3,8% (P < 0.001) and 2,5% (P = 0.026) during the FSH-stimulation when the estradiol levels were high. Cdis correlated significantly (P < 0.05) with systolic blood pressure, diastolic blood pressure and triglycerides in high estrogenic environment and with diastolic blood pressure (P < 0.05) when estrogen profiles were low. CONCLUSIONS Carotid artery stiffens during the high estradiol levels compared to low levels and this was not explained by the higher diameter of the carotid artery, hyperlipidemia or blood pressure profiles. All the changes in Cdis and Cdia are variations of normal, and if there is no history of cardiovascular problems, it can be considered, that the stimulation protocol is not hazardous to vasculature.

Abstract
AIMS The aim was to compare and describe maternal use of drugs between women with preeclampsia and controls and to estimate the possible association with preeclampsia. METHODS The study cohort was collected from the Kuopio University Hospital Birth Register, which includes information about all women who gave birth in Kuopio University Hospital during the years 2002-2016, including information from approximately 36 000 parturients, of whom 1252 had preeclampsia. Maternal use of 16 groups of drugs during pregnancy was analysed from all women with preeclampsia and 1256 controls. RESULTS Every second woman had used at least 1 drug during pregnancy but those with preeclampsia had used significantly more than the controls (cases 59.5% vs controls 35.5%; p < 0.001). In both study groups, the most commonly used drugs were antibiotics (cases 19.5%, controls 17.0%), antihypertensives (cases 29.0%, controls 7.6%) and paracetamol (cases 13.1%, controls 5.9%). Women with preeclampsia had used significantly more benzodiazepines, paracetamol, antihypertensives and acid-suppressive drugs than the women in the control group (p < 0.05). CONCLUSIONS Women with preeclampsia were more likely to use medicines during pregnancy. While the association between benzodiazepines, antihypertensives and acid-suppressive drugs and preeclampsia may be explained by reverse causation, the association of paracetamol with preeclampsia remains to be clarified. Because paracetamol is a frequently used drug, more information about its safety during pregnancy including its role in preeclampsia is urgently needed.

Abstract
BACKGROUND AND OBJECTIVE The farm environment, especially contact with farm animals in early childhood, may prevent allergic sensitization during adulthood. However, prospective associations between exposure to the farm environment and polysensitization have not been studied. Polysensitization is a risk factor for asthma and asthma-related morbidity. Objective: To investigate whether exposure to a farming environment in early childhood, especially exposure to animals, is associated with sensitization to specific allergens and polysensitization at the age of 31. METHODS In a prospective birth cohort study, 5509 individuals born in northern Finland in 1966 underwent skin prick testing against birch, timothy, cat, and house dust mite at the age of 31. Prenatal exposure to the farming environment was documented at birth, whereas information on childhood exposure to pets was only collected retrospectively at the age of 31. Data were analyzed using logistic regression. RESULTS Being born to a family with farm animals was associated with a reduced risk of sensitization to birch, timothy, and cat (adjusted odds ratio [aOR], 0.55 [95%CI, 0.43-0.70]; aOR, 0.62 [95%CI, 0.48-0.79]; aOR, 0.60 [95%CI, 0.47-0.75]) and polysensitization at the age of 31 (aOR, 0.62 [95%CI, 0.48-0.80]). The number of animal species present during childhood was dose-dependently associated with a reduced risk of sensitization to birch, timothy, and cat, as well as of polysensitization. No association was found with sensitization to house dust mite. CONCLUSIONS Growing up on a farm and contact with higher numbers of animal species in childhood are associated with less frequent sensitization to birch, timothy, and cat allergens and polysensitization in adulthood, but not with sensitization to house dust mite.

Abstract
Background In many malignancies including ovarian cancer, different angiogenic factors have been related to poor prognosis. However, data on their relations to each other or importance as a prognostic factor in ovarian cancer is missing. Therefore, we investigated the expressions of VEGF-A, VEGF-C, and VEGF-D, and the receptors VEGFR1, VEGFR2, and VEGFR3 in patients with malignant epithelial ovarian neoplasms. We further compared expression levels between primary tumors and related distant omental metastases. Methods This study included 86 patients with malignant ovarian epithelial tumors and 16 related distant metastases. Angiogenic factor expression was evaluated using immunohistochemistry (n = 102) and qRT-PCR (n = 29). Results Compared to primary high grade serous ovarian tumors, the related omental metastases showed higher expressions of VEGF-A (p = 0.022), VEGF-D (p = 0.010), and VEGFR1 (p = 0.046). In univariate survival analysis, low epithelial expression of VEGF-A in primary tumors was associated with poor prognosis (p = 0.024), and short progression-free survival was associated with high VEGF-C (p = 0.034) and low VEGFR3 (p = 0.002). The relative expressions of VEGF-D, VEGFR1, VEGFR2, and VEGFR3 mRNA determined by qRT-PCR analyses were significantly correlated with the immunohistochemically detected levels of these proteins in primary high grade serous ovarian cancer and metastases (p = 0.004, p = 0.009, p = 0.015, and p = 0.018, respectively). Conclusions The expressions of VEGF receptors and their ligands significantly differed between malignant ovarian tumors and paired distant metastases. VEGF-A, VEGF-D, and VEGFR1 protein expressions seem to be higher in distant metastases than in the primary high grade serous ovarian cancer lesions.

Abstract
OBJECTIVE Peripartum depression (PPD) pertaining to depression in pregnancy and postpartum is one of the most common complications around childbirth with enduring adverse effects on mother and child health. Although psychiatric symptoms may improve or worsen over time, relatively little is known about the course of PPD symptoms and possible fluctuations. METHODS We applied a person-centered approach to examine PPD symptom patterns across pregnancy and childbirth. 824 women were assessed at three time points: first trimester (T1), third trimester (T2), and again at eight weeks (T3) postpartum. We assessed PPD symptoms, maternal mental health history, and childbirth variables. RESULTS Growth mixture modeling (GMM) analysis revealed four discrete PPD symptom trajectory classes including chronic PPD (1.1%), delayed (10.2%), recovered (7.2%), and resilient (81.5%). Delivery complications were associated with chronic PPD but also with the recovered PPD trajectory class. History of mental health disorders was associated with chronic PPD and the delayed PPD class. CONCLUSION The findings underscore that significant changes in a woman's depression level can occur across pregnancy and childbirth. While a minority of women experience chronic PDD, for others depression symptoms appear to significantly alleviate over time, suggesting a form of recovery. Our findings support a personalized medicine approach based on the woman's symptom trajectory. Future research is warranted to identify the mechanisms underlying modifications in PPD symptoms severity and those implicated in recovery.

Abstract
BACKGROUND A Finnish joint research effort Kuopio Birth Cohort (KuBiCo) seeks to evaluate the effects of genetics, epigenetics and different risk factors (medication, nutrition, lifestyle factors and environmental aspects) during pregnancy on the somatic and psychological health status of the mother and the child. METHODS KuBiCo will ultimately include information on 10,000 mother-child pairs who have given their informed consent to participate in this cohort. Identification of foetal health risk factors that can potentially later manifest as disease requires a repository of relevant biological samples and a flexible open up-to-date data handling system to register, store and analyse biological, clinical and questionnaire-based data. KuBiCo includes coded questionnaire-based maternal background data gathered before, during and after the pregnancy and bio-banking of maternal and foetal samples that will be stored in deep freezers. Data from the questionnaires and biological samples will be collected into one electronic database. KuBiCo consists of several work packages which are complementary to each other: Maternal, foetal and placental metabolism and omics; Paediatrics; Mental wellbeing; Prenatal period and delivery; Analgesics and anaesthetics during peripartum period; Environmental effects; Nutrition; and Research ethics. DISCUSSION This report describes the set-up of the KuBiCo and descriptive analysis from 3532 parturients on response frequencies and feedback to KuBiCo questionnaires gathered from June 2012 to April 2016. Additionally, we describe basic demographic data of the participants (n = 1172). Based on the comparison of demographic data between official national statistics and our descriptive analysis, KuBiCo represents a cross-section of Finnish pregnant women.

Abstract
The purpose was to study the prevalence of environmental intolerance (EI) and its different manifestations, including behavioral changes and disability. Fertile-aged women (n = 680) of the Kuopio Birth Cohort Study were asked about annoyance to 12 environmental factors, symptoms and behavioral changes. We asked how much the intolerance had disrupted their work, household responsibilities or social life. We chose intolerance attributed to chemicals, indoor molds, and electromagnetic fields to represent typical intolerance entities. Of the respondents, 46% reported annoyance to chemicals, molds, or electromagnetic fields. Thirty-three percent reported symptoms relating to at least one of these three EIs, 18% reported symptoms that included central nervous system symptoms, and 15% reported behavioral changes. Indicating disability, 8.4% reported their experience relating to any of the three EIs as at least “somewhat difficult”, 2.2% “very difficult” or “extremely difficult”, and 0.9% “extremely difficult”. Of the latter 2.2%, all attributed their intolerance to indoor molds, and two thirds also to chemicals. As the number of difficulties increased, the number of organ systems, behavioral changes and overlaps of the three EIs also grew. EI is a heterogeneous phenomenon and its prevalence depends on its definition. The manifestations of EI form a continuum, ranging from annoyance to severe disability.

Abstract
AIM We aimed to determine whether maternal hemoglobin levels or anemia during pregnancy are associated with the development of asthma among offspring. METHODS Data were retrieved from the birth register database of Kuopio University Hospital between 1989 and 2007 (n = 38 381). Hemoglobin levels were measured during three trimesters of pregnancy and anemia was defined according to the World Health Organization criteria. The prevalence of asthma was determined from the register of reimbursement for medication for asthma at the Finnish Social Security Institution. Cox proportional hazard regression analysis was performed to evaluate the possible associations between prenatal factors and development of asthma ever. RESULTS A total of 8198 (21.4%) women had anemia at some stage of pregnancy. Mild maternal anemia during the first trimester was associated with an increased risk of asthma among male offspring (adjusted hazard ratio, 1.46; 95% confidence interval, 1.11-1.94) compared with those with normal maternal hemoglobin levels. This finding remained significant also after applying the Bonferroni correction. CONCLUSION Male offspring with maternal anemia during the first trimester of pregnancy had significantly more asthma ever than the offspring of women with normal hemoglobin levels during pregnancy. These findings were not strong but suggest possible sex-specific effects of maternal health on prenatal programming and future risk of asthma.

Abstract
BACKGROUND Respiratory tract infections and their symptoms are frequent during early childhood, but their risk factors, including the effect of early immune regulation, are less known. The aim of the study was to analyze whether stimulated cord blood cytokine production is associated with the frequency of respiratory tract infection symptoms or infections during the first year of life. METHODS The study population consisted of children of mothers from farm or non-farm rural environment from Austria, Finland, Germany, and Switzerland who participated in a prospective birth cohort study (PASTURE: Protection against Allergy-Study in Rural Environments) (N = 550). Cord blood samples were stimulated with the combination of phorbol ester and ionomycin (P/I) for 24 h, and the production of IL-5, IL-10, TNF-α, and IFN-γ was determined using ELISA. Information about infectious morbidity was collected using weekly diaries. RESULTS P/I-stimulated production of IL-5 (adjusted risk ratio (aRR) for ≤median production, 0.37; 95% confidence interval (CI), 0.25-0.55, aRR for >median production, 0.41; 95% CI, 0.27-0.61 vs. production <detection limit) and IFN-γ (aRR for ≤median production, 0.62; 95% CI, 0.40-0.95, aRR for >median production, 0.39; 95% CI, 0.25-0.62 vs. production <detection limit) in cord blood were associated with lower number of weeks with reported middle ear infection. There was a tendency toward positive association with P/I-stimulated TNF-α production and middle ear infections. CONCLUSION Our results suggest that increased Th2- and Th1-associated cytokine responses at birth may provide protection from later middle ear infections.

Abstract
Objective To evaluate the prevalence of various etiologies of epilepsies and epilepsy syndromes and to estimate cognitive function in cases of childhood‐onset epilepsy. Methods A population‐based retrospective registry study. We identified all medically treated children with epilepsy born in 1989–2007 in Finland's Kuopio University Hospital catchment area, combining data from the birth registry and the national registry of special‐reimbursement medicines. We reevaluated the epilepsy diagnoses and syndromes and gathered data on etiologies and cognitive impairment. Results We identified 289 children with epilepsy. The annual incidence rate of epilepsies and epilepsy syndromes was 38 in 100,000, and the misdiagnosis rate was 3%. A specific etiology was identified in 65% of the cases, with a structural etiology accounting for 29% and a genetic or presumed genetic etiology for 32%. Most patients with unknown‐etiology epilepsy had focal epilepsy and were of normal intelligence. Intellectual disability was detected in 35% of cases, and only 17% in this group had an unknown etiology for the epilepsy. Electroclinical syndromes (mainly West syndrome) were recognized in 35% of the patients. Significance Epilepsy is a complex disease that encompasses many etiologies and rare syndromes. The etiology and specific epilepsy syndrome are important determinants of the outcome and key factors in treatment selection. Etiological diagnosis can be achieved for the majority of children and syndromic diagnosis for only a third.

OBJECTIVE We wanted to determine whether genetic variability in the gene encoding microsomal epoxide hydrolase (EPHX) contributes to individual differences in susceptibility to the occurrence of placental abruption. METHODS The study involved 117 women with placental abruption and 115 healthy control pregnant women who were genotyped for two single nucleotide polymorphisms (SNPs), T-->C (Tyr113His) in exon 3 and A-->G (His139Arg) in exon 4, in the EPHX gene. Chi-square analysis was used to assess genotype and allele frequency differences between the women with placental abruption and the control group. In addition, single-point analysis was expanded to pair of loci haplotype analysis to examine the estimated haplotype frequencies of the two SNPs, of unknown phase, among the women with placental abruption and the control group. Estimated haplotype frequencies were assessed using the maximum-likelihood method, employing an expectation-maximization algorithm. RESULTS Single-point allele and genotype distributions in exons 3 and 4 of the EPHX gene were not statistically different between the groups. However, in the haplotype estimation analysis we observed a significantly decreased frequency of haplotype C-A (His113-His139) among the placental abruption group compared with the control group (P = .007). The odds ratio for placental abruption associated with the low-activity haplotype C-A (His113-His139) was 0.552 (95% confidence interval, 0.358 to 0.851). CONCLUSIONS The use of two intragenic SNPs jointly in haplotype analysis of association demonstrated that the genetically determined low-activity haplotype C-A (His113-His139) was significantly less frequent in women with placental abruption.

Abstract
Background To evaluate the association between maternal and paternal smoking during pregnancy, and asthma among offspring. Methods We conducted a hospital-based birth retrospective observational birth cohort study in a University-based Obstetrics and Gynecology Department, Kuopio University Hospital, Finland. 39 306 women, delivering between 1989 and 2006, were linked to the national register for asthma reimbursement for their offspring (2641 asthmatics). Pregnancy factors were recorded during pregnancy. Results The risk of asthma was significantly elevated if both parents smoked (aOR 3.7; 95 % Cl 3.2-4.4) and it remained high in only paternal smoking families (aOR 2.9; 95 % Cl 2.5-3.3) as well as only maternal smoking families (aOR 1.7; 95 % Cl 1.2-2.2). Paternal cessation of smoking during pregnancy seemed to reduce the risk of asthma regardless of maternal smoking (aOR 0.3-0.4). Conclusions Parental smoking, and especially paternal smoking, was significantly associated with the risk of asthma in offspring and paternal cessation of smoking during pregnancy was associated with a decreased risk of childhood asthma regardless of maternal smoking. The results indicate that both parents should be encouraged to quit smoking during pregnancy, since it is a relatively easy and cheap way to reduce the risk of asthma in offspring. Trial registration The study is registered in Kuopio University Hospital register (TUTKI): ID5302448

Abstract
The effects of maternal smoking on the term placental proteome was studied. Maternal smoking significantly affected 18% of protein spots. Maternal smoking affects systems controlling the development and function of placenta. The observed placental changes may contribute to the lowered birth weights.
Detrimental effects of maternal smoking on the term placental proteome and steroid-metabolizing activities, and maternal hormone levels, were studied by using seven non-smoker and seven smoker placentae. Smoking significantly affected 18% of protein spots. The functional networks affected were i) cell morphology, cellular assembly and organization, cellular compromise (15 hits) and ii) DNA replication, recombination, and repair, energy production, nucleic acid metabolism (6 hits). Smoking significantly up-regulated such proteins as, SERPINA1, EFHD1 and KRT8; and down-regulated SERPINB2, FGA and HBB. Although maternal plasma steroids were not significantly altered, the catalytic activity of CYP1A1 was increased whereas CYP19A1 activity was reduced by smoking. Furthermore, transcript expression of CYP1A1 and CYP4B1 were induced while HSD17B2, NFKB and TGFB1 were repressed by smoking. The observed smoking induced wide-spread changes on placental proteome and transcript levels may contribute to the lowered birth weights of the new-born child and placenta.

Abstract
BACKGROUND To evaluate the association between maternal socioeconomic status (SES) during pregnancy and asthma among offspring. METHODS A retrospective observational hospital-based birth cohort study in a university-based Obstetrics and Gynecology department in Finland. A total of 40 118 women with singleton live births between 1989 and 2007 were linked with data from the register for asthma medication for their offspring (n = 2518). Pregnancy and maternal SES factors were recorded during pregnancy and labor. SES was categorized thus: upper white-collar workers (highest SES), lower white-collar workers, blue-collar workers, others (lowest SES) and cases with missing information. Logistic regression analysis was used to determine the association between maternal SES and childhood asthma. RESULTS We found no convincing evidence of a direct association between maternal SES and childhood asthma. Parental smoking was the clearest factor affecting asthma among children of lower white-collar workers. Differences in pregnancy and delivery characteristics were observed between the SES groups. CONCLUSIONS Maternal socioeconomic status had no significant direct impact on the prevalence of asthma in this Finnish birth cohort. Finnish public health services appeared to offer equal quality services independently of SES. TRIAL REGISTRATION The study is registered in Kuopio University Hospital register (TUTKI): ID 5302448 .

Abstract
INTRODUCTION Many complications of pregnancy and delivery are associated with umbilical cord length. It is important to examine the variation in length, in order to identify normal and abnormal conditions. Moreover, the factors influencing cord growth and development are not precisely known. OBJECTIVE The main objectives were to provide updated reference charts for umbilical cord length in singleton pregnancies and to evaluate potential factors affecting cord length. METHODS Birth register data of 47,284 singleton pregnant women delivering in Kuopio University Hospital, Finland was collected prospectively. Gender-specific centile charts for cord length from 22 to 44 gestational weeks were obtained using generalized additive models for location, scale, and shape (GAMLSS). Gestational, fetal, and maternal factors were studied for their potential influence on cord length with single variable analysis and stepwise multiple linear regression analysis. RESULTS Cord length increased according to gestational age, while the growth decelerated post-term. Birth weight, placental weight, pregravid maternal body mass index, parity, and maternal age correlated to cord length. Gestational diabetes and previous miscarriages were associated with longer cords, while female gender and placental abruption were associated with shorter cords. DISCUSSION AND CONCLUSIONS Girls had shorter cords throughout gestation although there was substantial variation in length in both genders. Cord length associated significantly with birth weight, placental weight, and gestational age. Significantly shorter cords were found in women with placental abruption. This important finding requires further investigation.

Abstract
OBJECTIVE To evaluate the association between gestational age at birth and the risk of subsequent development of asthma. STUDY DESIGN We conducted a retrospective observational hospital-based birth case-control study in a university-based obstetrics and gynecology department in Finland. A total of 44,173 women delivering between 1989 and 2008 were linked with the social insurance register to identify asthma reimbursements for their offspring (n = 2661). Pregnancy factors were recorded during pregnancy. Infants were categorized as moderately preterm (≤ 32 weeks), late preterm (33-36 weeks), early term (37-38 weeks), term (39-40 weeks), or late term and postterm (≥ 41 weeks). The main outcome measure was asthma among the infants. RESULTS Children born moderately preterm (≤ 32 weeks gestation) had a significantly increased risk of asthma (aOR, 3.9; 95% CI, 3.2-4.8). The risk of asthma was also increased in those born late preterm (aOR, 1.7; 95% CI, 1.4-2.0) and early term (aOR, 1.2; 95% CI, 1.1-1.4). In contrast, delivery at 41 weeks or later seemed to decrease the risk of asthma (aOR, 0.9; 95% CI, 0.8-1.0). The burden of asthma associated with preterm birth was associated mainly with early term infants, in whom 108 extra cases of asthma were observed. CONCLUSION Even though the individual risk of asthma was inversely correlated with gestational age at birth, the overall burden brought about by delivery before term was associated with late preterm and early term deliveries. Furthermore, delivery after term was protective against asthma.

Abstract
BACKGROUND Microbial exposure may induce low-grade inflammation at an early age and decrease the risk of allergic diseases, as suggested by the hygiene hypothesis. We examined the associations between low-grade inflammation and the development of allergic sensitization, atopic dermatitis (AD), and asthma at the age of 4.5 yr. METHODS We studied 636 children participating in the PASTURE study in Finland, Germany, Austria, France, and Switzerland. Data of environmental factors, doctor-diagnosed AD, and asthma were collected by questionnaire. The serum high-sensitivity C-reactive protein (CRP) values were measured at the age of 1 yr, and serum-specific IgE concentrations (sIgE) at the age of one and 4.5 yr. Analyses were made by logistic regression analysis. RESULTS The risk of allergic sensitization at the age of 4.5 yr was decreased in children who had increased CRP levels at the age of 1 yr (level in the highest vs. lowest quartile: aOR 0.48, 95% CI 0.24-0.95; p = 0.014). The risk of AD and asthma was not significantly related to CRP. CONCLUSION The findings confirm that elevated levels of CRP at early age showed association with decreased allergic sensitization later in life. Our results suggest that poor inflammatory response could predispose for IgE sensitization.

Abstract
AIM To estimate the transmission of maternal vaginal microbiota to neonates during term delivery, focusing on Lactobacillus flora in relation to various obstetric clinical factors. METHODS Fifty consecutive pregnant healthy women with singleton term pregnancies and their newborn infants. Vertical transmission of Lactobacillus flora to the newborn during delivery was evaluated in 45 mother-newborn pairs. RESULTS Lactobacillus-dominant mixed flora was detected in 90% (N = 45) of vaginal samples, but only in 28% (N = 14) of neonatal cultures (transmission rate 31%). All neonates with Lactobacillus-dominant mixed flora had findings similar to those in maternal cultures. Cocci-dominant flora was the most common finding in neonates. Administration of antibiotics to the mother during the intrapartum period before birth and duration of rupture of membranes (ROM), regardless of maternal antibiotic treatment, were associated significantly with a decreased transmission rate of Lactobacillus-dominant mixed flora to neonates. CONCLUSION Maternal intrapartum antibiotics and prolonged expectant management after ROM were associated with decreased transmission rate of vaginal Lactobacillus flora to the neonate during birth. As early colonization of Lactobacillus flora may have a preventive role in the development of allergic diseases later, the significance of intrapartum prophylactic antibiotics needs to be highlighted in forthcoming studies, especially as regards immunological development of the offspring.

Abstract
OBJECTIVE To identify risk factors for true umbilical cord knot and to evaluate its association with fetal death, premature birth, low birth weight, small-for-gestational-age (SGA) infants, low Apgar score at 1 and 5 minutes, fetal venous pH of 7.15 or lower, and need for neonatal intensive care in singleton pregnancies. METHODS The total population of women who delivered at Kuopio University Hospital, Kuopio, Finland, between January 2000 and August 2012 was reviewed. Risk factors for umbilical cord knot and its association with adverse pregnancy outcome were evaluated separately among women with and without true cord knot via logistic regression analysis. RESULTS Overall, 340 (1.2%) of 27 537 singleton pregnancies were affected by umbilical cord knot, with increased incidence associated with advanced maternal age, multiparity, previous spontaneous abortion, polyhydramnios, and diabetes mellitus. Umbilical cord knot was associated with a 1.58-, 8.08-, 3.90-, 3.17-, 1.67-, and 2.00-fold increased risk of neonatal intensive care, fetal death, premature birth, SGA infants, and low Apgar score at 1 and 5 minutes, respectively. CONCLUSION True umbilical cord knot is relatively common and is associated with increased incidence of SGA infants, premature birth, need for neonatal intensive care, and fetal death.

Abstract
Background Epilepsy is one of the most common neurologic disorders of childhood, affecting about 0.4−0.8% of all children up to the age of 20. Methodology A population-based retrospective cohort study. Aim was to determine incidence and identify perinatal and reproductive risk factors of epilepsy in children born between 1989 and 2008 among women (n = 43,389) delivered in Kuopio University Hospital. Risk factors of childhood epilepsy were determined by using logistic regression analysis. Principal Findings The incidence of childhood epilepsy was 0.7% (n = 302 of 43,389). Maternal epilepsy, major congenital anomalies and use of assisted reproductive technology (ART) were associated with 4.25-, 3.61-, and 1.67- fold increased incidence of childhood epilepsy. A 10 cm increase in umbilical cord length was associated with a 15% decrease in the incidence of epilepsy (adjusted OR 0.85, 95% CI 0.78−0.94). However, the above reproductive factors accounted for less than 2% of total incidence, whereas maternal epilepsy proved to be the highest risk factor. Conclusions Perinatal and reproductive factors were shown to be minor risk factors of childhood epilepsy, implying that little can be done in obstetric care to prevent childhood epilepsy. Infertility treatment and umbilical cord length, independent of gestational age and congenital malformations, may be novel markers of childhood epilepsy.

Abstract
BACKGROUND Early-life exposure to environmental microbial agents may be associated with development of wheezing and allergic diseases. OBJECTIVE To assess the association of microbial exposure in rural homes with the risk of asthma, wheezing, atopic dermatitis and sensitization. METHODS Birth cohorts of rural children (n = 1133), half from farmer families, were followed up from birth to 2 years of age by questionnaires in five European centres. Endotoxin and extracellular polysaccharides (EPS) of Penicillium and Aspergillus spp. were determined from living room floor and mother's mattress dust samples collected at 2 months of age. Specific IgE against 19 allergens was measured at 1 year of age. Discrete-time hazard models, generalized estimations equations (GEE) and logistic regression were used for statistical analyses. RESULTS The incidence of asthma was inversely associated with the amount of dust (adjusted odds ratio (aOR) 0.73, 95% CI 0.58-0.93) and the loads (units/m(2)) of EPS (aOR 0.75, 95% CI 0.55-1.04) and endotoxin (aOR 0.79, 95% CI 0.60-1.05) in the mother's mattress. Similar associations were seen with wheezing and with living room floor dust. The microbial markers were highly correlated and their effects could not be clearly separated. The inverse associations were seen especially among non-farmers. The risk of sensitization to inhalant allergens increased with increasing endotoxin exposure from mattress dust. No associations were observed with concentrations (units/g) or with atopic dermatitis. CONCLUSION AND CLINICAL RELEVANCE The amount and microbial content of house dust were inversely associated with asthma and wheezing, but due to high correlations between microbial agents and amount of dust, it was not possible to disentangle their individual effects. New ways to better measure and represent exposure to environmental microbes, including indexes of biodiversity, are needed especially among farmers.

Abstract
BACKGROUND Low-grade inflammation in early childhood might protect from allergic diseases later in life. Our aim was to examine the effects of different environmental factors on low-grade inflammation measured with serum high-sensitivity C-reactive protein (hsCRP) at the age of 4.5 years. METHODS The high-sensitivity CRP values (n = 653) and serum-specific IgE concentrations were measured from 4.5-year-old children in rural areas in five European countries (Austria, Finland, France, Germany, and Switzerland). Children belonged to the prospective multi-center PASTURE birth cohort. Data on early and current farming environment and domestic animal exposure were collected by questionnaires. RESULTS Females as well as obese or very obese children at age of 4.5 years had higher hsCRP values than males (aOR 1.84 95% CI 1.27-2.66) and healthy weight children (aOR 4.47 95% CI 1.94-10.31), respectively. Levels were lowest in the summer. Few associations were detected between hsCRP values and farm environmental factors or atopic sensitization. However, there was evidence of children with low levels of hsCRP (below the detection limit) who had increased prevalence of sensitization to inhaled and seasonal allergens. Among non-sensitized children, spending time in stables was associated with reduced hsCRP (15 min-10 h aOR 0.40 95% CI 0.16-0.96 and ≥10 h aOR 0.25 95% CI 0.07-0.90), and among sensitized children, maternal smoking was associated with higher hsCRP values (aOR 2.51 95% CI 1.12-5.59). CONCLUSION We found few associations between early environmental farming factors and hsCRP levels, and between hsCRP levels and atopic sensitization in 4.5-year-old children. However, our results suggest that the role played by the environmental factors in low-grade inflammation may differ between sensitized and non-sensitized children.

Abstract
OBJECTIVES To investigate the effect of dog and cat contacts on the frequency of respiratory symptoms and infections during the first year of life. METHODS In this birth cohort study, 397 children were followed up from pregnancy onward, and the frequency of respiratory symptoms and infections together with information about dog and cat contacts during the first year of life were reported by using weekly diaries and a questionnaire at the age of 1 year. All the children were born in eastern or middle Finland between September 2002 and May 2005. RESULTS In multivariate analysis, children having dogs at home were healthier (ie, had fewer respiratory tract symptoms or infections) than children with no dog contacts (adjusted odds ratio, [aOR]: 1.31; 95% confidence interval [CI]: 1.13-1.52). Furthermore, children having dog contacts at home had less frequent otitis (aOR: 0.56; 95% CI: 0.38-0.81) and tended to need fewer courses of antibiotics (aOR: 0.71; 95% CI: 0.52-0.96) than children without such contacts. In univariate analysis, both the weekly amount of contact with dogs and cats and the average yearly amount of contact were associated with decreased respiratory infectious disease morbidity. CONCLUSIONS These results suggest that dog contacts may have a protective effect on respiratory tract infections during the first year of life. Our findings support the theory that during the first year of life, animal contacts are important, possibly leading to better resistance to infectious respiratory illnesses during childhood.

Abstract
BACKGROUND Intrapartum factors may have a role in the development of asthma and allergic diseases among offspring. OBJECTIVE To investigate the association between umbilical arterial pH values at birth and asthma, allergic rhinitis, and atopic eczema in children. METHODS We performed a case-control study of 222 asthmatic children and 183 control children aged 5 to 6 years with umbilical artery pH values recorded at birth. Associations were evaluated using logistic regression analysis. RESULTS Asthmatic children had significantly lower umbilical artery pH values at birth than nonasthmatics, even after adjusting. Children who were born with pH values of 7.20-7.25 had a 2.62-fold (95% confidence interval [CI], 1.31-5.23) higher risk of asthma and children who were born with umbilical arterial pH values < or = 7.19 had a 3.22-fold (95% CI, 1.51-6.87) higher risk of asthma than children who were born with umbilical arterial pH values of 7.26-7.30. In contrast, children who were born with umbilical arterial pH values > or = 7.30 had a 0.41-fold lower risk of atopic eczema than children who were born with umbilical arterial pH values of 7.26-7.30. No such association was detected between umbilical artery pH values and allergic rhinitis. CONCLUSIONS Stressful events at birth may play an important role in the development of asthma during early childhood. In contrast, higher umbilical arterial pH values were associated with a decreased risk of parent-reported atopic eczema at 5-6 years.

Abstract
BACKGROUND Cross-sectional studies have shown an association between the farming environment and a decreased risk of atopic sensitization, mainly related to contact with farm animals in the childhood. OBJECTIVE Investigate the association of a farming environment, especially farm animal contact, during infancy, with atopic sensitization and allergic diseases at the age of 31. METHODS In a prospective birth cohort study, 5509 subjects born in northern Finland in 1966 were followed up at the age of 31. Prenatal exposure to the farming environment was documented before or at birth. At age 31, information on health status and childhood exposure to pets was collected by a questionnaire and skin prick tests were performed. RESULTS Being born to a family having farm animals decreased the risk of atopic sensitization [odds ratio (OR) 0.67; 95% confidence interval (CI) 0.56-0.80], atopic eczema ever (OR 0.77; 95% CI 0.66-0.91), doctor-diagnosed asthma ever (OR 0.74; 95% CI 0.55-1.00), allergic rhinitis at age 31 (OR 0.87; 95% CI 0.73-1.03) and allergic conjunctivitis (OR 0.86; 95% CI 0.72-1.02) at age 31. There was a suggestion that the reduced risk of allergic sensitization was particularly evident among the subjects whose mothers worked with farm animals during pregnancy, and that the reduced risk of the above diseases by farm animal exposure was largely explained by the reduced risk of atopy. Having cats and dogs in childhood revealed similar associations as farm animals with atopic sensitization. CONCLUSION AND CLINICAL RELEVANCE Contact with farm animals in early childhood reduces the risk of atopic sensitization, doctor-diagnosed asthma and allergic diseases at age 31.

Abstract
BACKGROUND The effect of labour and different labour-related factors on the cord blood (CB) cell cytokine production is still relatively unknown. OBJECTIVE To study the relationships between the production of IL-5, IL-10 and IFN-γ in CB samples and maternal, early neonatal and birth-related factors. METHODS Whole-blood samples were collected after birth (n=423) and they were stimulated for 24 and 48 h with a combination of phorbol ester and ionomycin. Production of IL-5, IL-10 and IFN-γ was determined using ELISA. Maternal, early neonatal and birth-related variables were recorded prospectively during pregnancy, and during and after delivery. RESULTS After multivariable adjustment for confounders, the strongest predictor of IL-5, IL-10 and IFN-γ production in CB cell samples was the season of birth. Children born in the spring had significantly lower cytokine responses compared with those born in the fall. IL-5 production was inversely associated with female gender of the child and maternal smoking. If corrections for white blood cell (WBC) counts were not performed, IL-5 production was also significantly associated with the mode of delivery. Respectively, the production of IL-10 and IFN-γ was inversely associated with prostaglandin induction before birth. CONCLUSION Environmental exposure to pollen and ultraviolet irradiation during gestation may have an effect on the cytokine profile of the offspring in CB because children born in the spring or winter showed the lowest IL-5, IL-10 and IFN-γ responses. The production of IL-10 and IFN-γ was also inversely associated with prostaglandin labour induction before birth. Other labour-related factors were not significantly associated with production of IL-5, IL-10 and IFN-γ after WBC count correction.
