RESUMO

A too-high gestational weight gain, in combination with steadily increasing obesity rates among women of reproductive age, represents an enormous obstetrical problem, as obesity and high gestational weight gain are associated with enhanced fetal growth, low vital parameters, and increased cesarean section rates. This medical record-based study investigates the association patterns between too-low as well as too-high gestational weight gain, according to the 2009 Institute of Medicine (IOM) guidelines, and fetal growth, as well as birth mode and pregnancy outcome. The data of 11,755 singleton births that had taken place between 2010 and 2020 at the Public Clinic Donaustadt in Vienna, Austria, were analyzed. Birth weight, birth length, head circumference, APGAR scores, and pH values of the arterial umbilical cord blood described fetal growth as well as the vital parameters after birth. Gestational weight gain was classified as too low, recommended, or too high according to the different weight status categories of the IOM guidelines. Birth weight, birth length, and head circumference of the newborn were significantly increased (p < 0.001) among underweight, normal-weight, and overweight women who gained more weight than recommended. Among obese women, only birthweight was significantly (p < 0.001) higher among women who gained more weight than recommended. Furthermore, a too-high gestational weight gain was significantly associated with an increased risk of macrosomia and emergency cesarean sections among underweight, normal-weight, and overweight women, but not among obese ones. Obese and morbidly obese women experiencing excessive gestational weight gain showed no significantly increased risk of macrosomia or emergency cesarean section. However, among obese mothers, a too-low gestational weight gain reduced the risk of emergency cesarean sections significantly (p = 0.010). Consequently, the IOM recommendations for gestational weight gain fit only partly for pregnant women in Austria. In the case of obese and morbidly obese women, new guidelines for optimal pregnancy weight gain should be considered.

RESUMO

The increasing obesity rates among women of reproductive age create a major obstetrical problem as obesity during pregnancy is associated with many complications, such as a higher rate of caesarean sections. This medical record-based study investigates the effects of maternal prepregnancy obesity on newborn parameters, birth mode, and miscarriage rate. The data of 15,404 singleton births that had taken place between 2009 and 2019 at the public Danube Hospital in Vienna were enrolled in the study. Newborn parameters are birth weight, birth length, head circumference, APGAR scores, as well as pH values of the arterial and venous umbilical cord blood. In addition, maternal age, height, body weight at the beginning and the end of pregnancy, and prepregnancy body mass index (BMI) (kg/m2) have been documented. The gestational week of birth, the mode of delivery, as well as the number of previous pregnancies and births, are included in the analyses. Birth length, birth weight, and head circumference of the newborn increase with increasing maternal BMI. Furthermore, with increasing maternal weight class, there tends to be a decrease in the pH value of the umbilical cord blood. Additionally, obese women have a history of more miscarriages, a higher rate of preterm birth, and a higher rate of emergency caesarean section than their normal-weight counterparts. Consequently, maternal obesity before and during pregnancy has far-reaching consequences for the mother, the child, and thus for the health care system.

RESUMO

OBJECTIVES: The association patterns between breech presentation at birth and fetal biometry at the first, second, and third trimesters, newborn size but also maternal age, body height, prepregnancy weight status as well as gestational weight gain, were analyzed using a dataset of 4501 singleton term birth in Vienna, Austria. METHODS: In this medical record-based study, fetal biometry was reconstructed based on the results of three ultrasound examinations conducted at the 11th/12th, 20th, and 32nd gestational weeks. Head dimensions, abdominal dimensions, and femur length were determined by sonography. Birth weight, birth length, and head circumference were measured immediately after birth. RESULTS: The total breech presentation rate at birth was 6.2%. Breech newborns were significantly (p < 0.001) shorter and lighter at the time of birth, their head circumferences, however, were significantly larger (p = 0.001). At the 32nd week, breech fetuses showed significantly smaller biparietal breadths, but highly significantly longer heads. Their abdominal dimensions were significantly smaller, and their femora were shorter. Higher maternal age, and a longer, but narrower fetal head as well as smaller abdominal dimensions at the 32nd gestational week were independently related to a higher risk of breech presentation at the time of birth. CONCLUSIONS: Fetuses who remain in a breech presentation until term birth (≥37 gestational weeks) differed significantly in head and abdominal dimensions from cephalic fetuses from the 32nd gestational week onwards.

RESUMO

The COVID 19 pandemic represents a major stress factor for non-infected pregnant women. Although maternal stress during pregnancy increases the risk of preterm birth and intrauterine growth restriction, an increasing number of studies yielded no negative effects of COVID 19 lockdowns on pregnancy outcome. The present study focused on pregnancy outcome during the first COVID 19 lockdown phase in Austria. In particular, it was hypothesized that the national lockdown had no negative effects on birth weight, low birth weight rate and preterm birth rate. In a retrospective medical record-based single center study, the outcome of 669 singleton live births in Vienna Austria during the lockdown phase between March and July 2020 was compared with the pregnancy outcome of 277 live births at the same hospital during the pre-lockdown months of January and February 2020 and, in addition, with the outcome of 28,807 live births between 2005 and 2019. The rate of very low gestational age was significantly lower during the lockdown phase than during the pre-lockdown phase. The rate of low gestational age, however, was slightly higher during the lockdown phase. Mean birth weight was significantly higher during the lockdown phase; the rates of low birth weight, very low birth weight and extremely low birth weight were significantly lower during the lockdown phase. In contrast, maternal gestational weight gain was significantly higher during the lockdown phase. The stressful lockdown phase in Austria seems to have no negative affect on gestational length and newborn weight among non-infected mothers.

RESUMO

The association patterns between fetal biometry at the first, second and third trimester and neonatal size were analyzed using a dataset of 3814 singleton term birth taking place at the Viennese Danube hospital in Austria between 2005 and 2013. In this electronic medical record-based study, fetal biometry was estimated by the results of three ultrasound examinations carried out at the 11th/12th, 20th/21th and 32nd/33rdweek of gestation. In detail, crown-rump length, biparietal diameter, fronto-occipital diameter, head circumference, abdominal transverse diameter, abdominal anterior-posterior diameter, abdominal circumference, and femur length were determined. Birth weight, birth length and head circumference were measured within one hour after birth. Fetal head size, abdominal dimensions and femur length intercorrelated positively from the second trimester onwards and correlated significantly positively with neonatal size (r = 0.04 to 0.46). Despite these allometric associations between fetal and newborn parameters, principal component analyses showed that parameters indicating body fat/weight, head or brain size and skeletal growth load on separate components. Consequently, under optimal circumstances during pregnancy, head growth, fat accumulation and skeletal growth show independent incremental patterns from the second trimester onwards.

RESUMO

OBJECTIVE: The aim of the study was to assess genotype-phenotype correlation of prenatally diagnosed fetal DGS and dup22q11 syndrome by fetal molecular genetic analysis, fetal ultrasound, and/or MRI. METHODS: In this retrospective consecutive case series, pregnant women were screened for fetal anomalies during a period of 10 years. Fetal genotype was assessed in 72 cases upon the occurrence of five prenatal fetal phenotypic features: cardiac anomalies, hypo/aplastic thymus, craniofacial malformations, urinary abnormalities, or IUGR; genotype-phenotype correlation was tested to potentially improve prenatal diagnosis of fetal DGS and dup22q11 syndrome. RESULTS: Fetal genotypes of deletions or duplications in proximal clusters of LCR22s (A-B) were associated with fetal cardiac anomalies in combination with hypo/aplastic thymus and craniofacial malformations, suggesting a correlation with deleted HIRA. TOF associated with aplastic thymus in combination with renal defects indicated a relevant correlation with TBX1 deletion. Deletions in central LCR22s (B-D) with the loss of CRKL supposed a trend of genotype-phenotype correlation with fetal urinary abnormalities. CONCLUSION: Genotype-phenotype correlation might improve prenatal diagnosis of fetal DGS and dup22q11 syndrome. Hence, prenatal screening and counseling is highly enhanced by a combination of fetal molecular genetic analysis, fetal ultrasound, and/or MRI. The implications of these findings remain to be explored.

RESUMO

This is a case report of an isolated congenital radial head dislocation (CRHD) presenting after a breech delivery. The implications of this delivery mode led to the misdiagnosis of an elbow luxation. We found that elbow luxation is a common misdiagnosis of CRHD, although it has not been reported in children younger than one year. For the experienced clinician, repeated examinations and appropriate imaging usually lead to the exclusion of such misdiagnoses. CRHD itself usually remains asymptomatic until adolescence. Without pain or functional impairment of the joint, no specific therapy is needed. This case prompted us to provide an overview of elbow pathologies presenting at birth.

RESUMO

Caesarean section (CS) rates are increasing in many parts of the world, recently reaching about 20% worldwide. The postmodern lifestyle characteristics, obesity and delayed childbirth, have been put forward as the main reasons for high CS rates. The present study tests the association patterns between lifestyle parameters and delivery mode on a data set of 3786 births in Vienna between 2005 and 2013. The focus is exclusively on singleton term births. As well as maternal age, prepregnancy weight status, maternal body height and gestational weight gain, newborn size (birth weight, birth length, and head circumference), Apgar scores and child presentation were recorded. Planned as well as emergency CS rates increased significantly (p < 0.0001) with increasing maternal age and decreasing maternal body height. Emergency CS rates, however, increased significantly with increasing maternal prepregnancy weight status and gestational weight gain. An especially high risk of emergency CS occurred among four groups of mothers: those older than 40 years (OR = 2.68; 95% CI 1.87⁻3.86), those who were obese (OR = 1.44; 95% 1.15⁻1.81), those experiencing a gestational weight gain above 15 kg (OR = 1.32; 95% CI 1.13⁻1.54), and those shorter than 160 cm (OR = 1.216; 95% CI 1.02⁻1.45). Emergency CS rates were significantly higher among low-weight newborns (<2500 g) and macrosome newborns (>4000 g) than among normal-weight newborns. Furthermore, breech presentation was associated with an increased risk of caesarean delivery (OR 6.97; 95% CI 6.09⁻7.96). Logistic regression analyses reveal that maternal age, maternal body height, prepregnancy weight status, gestational weight gain, birth weight, newborn head circumference and child presentation show an independent, highly significant association with caesarean delivery. We conclude that maternal and newborn characteristics typical of recent lifestyle patterns, such as advanced maternal age, obesity, increased gestational weight gain and increased newborn size, are highly significantly associated with increased emergency CS rates. Moreover, maternal shortness and breech presentation are risk factors for emergency CS.

RESUMO

OBJECTIVE: The morphologic features of embryos with full trisomy 15 are described. METHOD: A total of 1195 pregnancy losses were examined embryoscopically and cytogenetically. RESULTS: Of 1173 successfully karyotyped specimens, full trisomy 15 was diagnosed cytogenetically in 59 cases (5%). All 59 trisomy 15 embryos were diagnosed cytogenetically in the group of 962 embryonic miscarriages (6%). Trisomy 15 was not registered in 171 anembryonic or yolk sac miscarriages, and no case of full trisomy 15 was observed in 62 fetal miscarriages. Fifty-eight embryos with full trisomy 15 showed structural defects on embryoscopic examination. The most common defects were craniofacial anomalies (n = 73), retarded development of the limbs (n = 39), and abnormally short umbilical cords closely attaching the embryo to the chorionic plate (n = 27). Seven embryos were classified as growth disorganized. Limb reduction defects with a prevalence of 5.6/10 000 births, all affecting upper limb development (10 terminal transverse limb reduction defects and 3 embryos with split hand), were registered in 13 (22%) trisomy 15 embryos. CONCLUSION: Limb reduction defects and craniofacial abnormalities are a typical feature of trisomy 15. Gene dosage imbalances related to trisomy 15 might be the main molecular mechanism underlying the developmental defects observed in the present study and require further investigation.

RESUMO

OBJECTIVE: Aim of the study was to assess the correlation of first trimester serum afamin levels with three-dimensional placental bed vascularization in pregnant women and its prognostic value for predicting pre-eclampsia and future fetal and maternal complications during pregnancy. METHODS: In this nested case-control study all pregnant women registered for delivery during a period of 3 years were routinely screened in the first trimester. Serum afamin levels were assessed in 764 women and correlated to 5 pregnancy outcome groups: gestational hypertension (n = 76), pre-eclampsia (n = 33), intrauterine growth restriction (n = 91), pre-term birth (n = 39), gestational diabetes mellitus (n = 170); In addition, measurements of first trimester myometrial vascularization index were performed and, in combination with afamin tested as a possible screening method to detect women at-risk for the development of adverse complications in low-risk pregnancies at the time of the first trimester. RESULTS: The results showed significantly higher serum afamin levels in women with pre-eclampsia (P<.05) and gestational diabetes mellitus (P<.05) compared to healthy pregnant women. There was no significant difference in serum afamin levels between all other pregnancy outcome groups and healthy controls. In women developing pre-eclampsia during pregnancy, afamin (OR = 1.0197, P < .05) and myometrial vascular index (OR = 0.9235, P < .001) were verified to have a significant prognostic value. Detection of pre-eclampsia in first trimester screening by a combination of afamin and myometrial vascular index performed best (AUC = 0.818). DISCUSSION: Hence, first trimester screening for pre-eclampsia could be provided by a combination of afamin and placental bed vascularization. Moreover, the combination of first trimester serum afamin levels with BMI could provide a possible screening for gestational diabetes mellitus.

RESUMO

OBJECTIVE: To assess the cytogenetic and embryoscopic characteristics of primary and secondary recurrent pregnancy loss. DESIGN: Clinical prospective descriptive study. SETTING: Tertiary care center. PATIENT(S): Nine hundred and eighty-four women affected by first-trimester pregnancy loss; 145 patients with recurrent pregnancy loss (RPL) and 839 patients with nonrecurrent pregnancy loss as controls. INTERVENTION(S): Transcervical embryoscopic examination of the embryo before uterine evacuation, and cytogenetic analysis of the chorionic villi by standard G-banding cytogenetic techniques. MAIN OUTCOME MEASURE(S): Aneuploidy frequency in the primary and secondary RPL group and the nonrecurrent pregnancy loss (non-RPL) control group. RESULT(S): Patients with RPL showed statistically significantly fewer aneuploid pregnancy losses (odds ratio [OR] 0.596; 95% confidence interval [CI], 0.40-0.88). Primary RPL was associated with lower aneuploidy rates compared with the non-RPL group (OR 0.423; 95% CI, 0.27-0.66) while secondary RPL was not (OR 1.414; 95% CI, 0.67-2.99). Patients with primary RPL had statistically significantly more morphologically normal embryos compared with non-RPL and secondary RPL. CONCLUSION(S): Patients' embryos after primary and secondary RPL show distinctive differences in aneuploidy and morphologic defect rates. These findings suggest different treatment approaches for the patients with primary and secondary RPL.

RESUMO

The impact of maternal height, pre-pregnancy weight status and gestational weight gain on fetal growth patterns and newborn size was analysed using a dataset of 4261 singleton term births taking place at the Viennese Danube Hospital between 2005 and 2013. Fetal growth patterns were reconstructed from three ultrasound examinations carried out at the 11th/12th, 20th/21th and 32th/33th weeks of gestation. Crown-rump length, biparietal diameter, fronto-occipital diameter, head circumference, abdominal transverse diameter, abdominal anterior-posterior diameter, abdominal circumference and femur length were determined. Birth weight, birth length and head circumference were measured immediately after birth. The vast majority of newborns were of normal weight, i.e. between 2500 and 4000 g. Maternal height showed a just-significant but weak positive association (r=0.03: p=0.039) with crown-rump length at the first trimester and with the majority of fetal parameters at the second trimester (r>0.06; p0.09; p0.08; p0.17; p0.13; p0.13; p<0.001), were significantly positively associated with newborn size. Some of these associations were quite weak and the statistical significance was mainly due to the large sample size. The association patterns between maternal height and pre-pregnancy weight status with fetal growth patterns (p<0.001), as well as newborn size (p<0.001), were independent of maternal age, nicotine consumption and fetal sex. In general, taller and heavier women gave birth to larger infants. This association between maternal size and fetal growth patterns was detectable from the first trimester onwards.

RESUMO

According to the male disadvantage hypothesis male foetuses react more sensitive to maternal stress factors during gestation. In the present study the gender typical impact of maternal prepregnancy overweight and obesity as well as gestational weight gain on newborn somatometrics was tested on basis of births records of 7565 births, which took place in Vienna Austria. Maternal weight status was determined at the beginning of pregnancy according to the WHO recommendations. Newborns were measured immediately after birth. With increasing maternal prepregnancy weight status and increasing gestational weight gain birth weight, birth length and head circumference increased too. Among male newborns however the increase was lower than among female ones. With increasing maternal weight status the prevalence of macrosome newborns increased significantly. Among girls however this increase was significantly higher. Male foetuses seem to react more sensitive to a higher maternal weight status in comparison to girls. These results can be interpreted in sense of the so called male disadvantage hypothesis.

RESUMO

OBJECTIVE: This study investigated the satisfaction of women carrying the LNG-IUD and determined influencing factors, especially considering bleeding patterns and body mass index (BMI). DESIGN: Cross sectional study. SETTING: Gynecological offices in a Central European district. PARTICIPANTS: 1825 women aged between 18 and 60 years. MEASUREMENT: While sitting in the waiting room, voluntary patients had to answer a questionnaire about their experiences with the levonorgestrel intrauterine device. One question was used to determine whether the women were current, former or not users of the intrauterine coil. RESULTS: 415 women who had some experiences with Mirena were found. Overall, 266 (65.7%) were "very satisfied," 83 (20.5%) "quite satisfied," 18 (4.4%) "moderate satisfied," 19 (4.7%) "less satisfied," and the same amount "really not satisfied" with the hormonal coil. Women with amenorrhea were more often "very satisfied" in general, than women with hypermenorrhea (178 (67.9%) vs. 3 (1.1%) p < 0.001). Concerning bleeding patterns, 295 (74.1%) were "very satisfied" and 23 (5.8%) "really not satisfied". 203 (91.0%) of all amenorrhoeic women were "very satisfied" with their bleeding patterns, but only 2 (9.5%) of all women with hypermenorrhea (p < 0.001 for α = 0.05). Amenorrhea particularly occurred in women who had a significantly lower body mass index (24.4 ± 4.4 kg/m(2) vs. 27.6 ± 6.5 kg/m(2) in women with hypermenorrhea, p = 0.018 for α = 0.05). After allocating women to the widely used BMI-categories (underweight, normal weight, overweight, obese class I and II) it was evident, that normally weighted women tend toward amenorrhea as well at the beginning of LNG-IUD use as well after 4-5 years of use. In contrast to this, overweighed and obese women tend more often to amenorrhea at the end of use, but not at the beginning (72.7% and 55.6% vs. 25.0% and 0%). Women with a lower BMI were more often "very satisfied" concerning bleeding patterns, but not concerning the general satisfaction. CONCLUSION: Our study showed much evidence, that amenorrhea occurs more often in women with lower BMI contrary to women with a higher one-especially at the beginning of LNG- IUD use. Furthermore amenorrhea was mostly considered to be a positive menstrual change.

RESUMO

There is evidence that LDL oxidation may render the lipoprotein atherogenic. The myeloperoxidase-hydrogen peroxide (MPO/H2O2) system of activated phagocytes may be involved in this process. Chloride is supposed to be the major substrate for MPO, generating reactive hypochlorous acid (HOCl), modifying LDL. The pseudo-halide thiocyanate (SCN-) has been shown to be a suitable substrate for MPO, forming reactive HOSCN/SCN*. As relatively abundant levels of SCN- are found in plasma of smokers--a well-known risk group for cardiovascular disease--the ability of SCN- to act as a catalyst of LDL atherogenic modification by MPO/H2O2 was tested. Measurement of conjugated diene and lipid hydroperoxide formation in LDL preparations exposed to MPO/H2O2 revealed that SCN- catalyzed lipid oxidation in LDL. Chloride did not diminish the effect of SCN- on lipid oxidation. Surprisingly, SCN inhibited the HOCl-mediated apoprotein modification in LDL. Nitrite--recently found to be a substrate for MPO--showed some competing properties. MPO-mediated lipid oxidation was inhibited by heme poisons (azide, cyanide) and catalase. Ascorbic acid was the most effective compound in inhibiting the SCN- -catalyzed reaction. Bilirubin showed some action, whereas tocopherol was ineffective. When LDL oxidation was performed with activated human neutrophils, which employ the MPO pathway, SCN- catalyzed the cell-mediated LDL oxidation. The MPO/H2O2/SCN- system may have the potential to play a significant role in the oxidative modification of LDL--an observation further pointing to the link between the long-recognized risk factors of atherosclerosis: elevated levels of LDL and smoking.

RESUMO

The mammary mouse tumor virus (MMTV) has been related to human breast cancer in previous studies, but these have yielded contradictory results. An MMTV env gene-like sequence was detectable in a relatively high proportion (38%) of human breast cancer tissues. The aim of this study was to determine the proportion of this 660 bp MMTV env gene-like sequence in a population of Austrian breast cancer patients. We performed PCR, repeat PCR, and nested PCR. We did not find any exogenous MMTV env gene sequences in the 50 DNA samples of human breast cancer tissue nor in 22 breast cancer cell lines including MCF-7, which has previously been described as a positive control.

RESUMO

The associations between cigarette smoking before and during pregnancy and maternal body size (pre-pregnancy weight status, end of pregnancy weight status, weight gain during pregnancy) and newborn size (birth weight, length, head circumference, arcomial circumference), as well as birth modus, were tested in 7803 single full-term births in Vienna. Nicotine consumption before and during pregnancy was found to be associated with smaller and lighter newborns, although maternal weight status and weight gain during pregnancy was significantly higher in smokers. Furthermore, a higher incidence of Caesarean sections was found in smokers. A reduction in the number of daily smoked cigarettes was associated with a lower percentage of low weight newborns (<2500 g).

RESUMO

Pregnancies during early adolescence were commonly thought to represent special risks, such as preterm delivery or low-weight newborns, resulting in increased mortality and morbidity of mother and child. An important biopsychosocial interaction can be assumed. In the present study the impact of maternal age and maternal somatic characteristics such as prepregnancy weight, stature, or pregnancy weight gain on newborn somatometric features (birth weight, birth length, head circumference, and arcomial circumference) using a dataset of 8,011 single term births were analyzed. The offspring of 215 extremely young mothers ages 12-16 years were significantly (P < 0.0001) lighter and smaller in all body dimensions than the offspring of older adolescent mothers, ages 17-19 years, and the offspring of adult gravida, ages 20-29 years, although no increased incidence of low-weight newborns (<2,500 g) could be observed. As expected, the youngest mothers were also significantly smaller and lighter than their older, biologically more mature counterparts, although the relative weight gain during pregnancy was highest in the youngest age group (23.4% vs. 22.9 and 22.1%, respectively). In general, age but also pregnancy weight gain and prepregnancy weight status were significantly associated with pregnancy outcome. Within term births taking place under sufficient psychosocial support, maternal somatic features had an important impact on newborn size.

RESUMO

The so-called prophylactic ovariectomy, i.e. the removal of macroscopically nonpathological ovaries during laparotomy or vaginal hysterectomy, does not always prevent ovarian cancer. A case of a 76-year-old woman with a Müllerian tumor is reported, and the literature will be discussed.
