    Although there is limited evidence that antepartum testing decreases the risk for fetal death in low-risk pregnancies, women with high-risk factors for stillbirth should undergo antenatal fetal surveillance. The strongest evidence supporting antepartum testing pertains to pregnancies complicated by intrauterine fetal growth restriction secondary to uteroplacental insufficiency. The main ultrasound-based modalities to determine fetal health are the biophysical profile, modified biophysical profile, and duplex Doppler velocimetry. In patients at risk for cardiovascular compromise, fetal echocardiography may also be indicated to ensure fetal well-being. Although no single antenatal test has been shown to be superior, all have high negative predictive values. Weekly or twice-weekly fetal testing has become the standard practice in high-risk pregnancies. The timing for the initiation of assessments of fetal well-being should be tailored on the basis of the risk for stillbirth and the likelihood of survival with intervention. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer-reviewed journals and the application of well-established methodologies (the RAND/UCLA Appropriateness Method and the Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances in which evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment. Copyright © 2016 American College of Radiology.

    All of the testing methods described above are very good at predicting continued fetal health when test results are reassuring. Each test also suffers from a very poor ability to predict compromise when results are abnormal. Thus, the primary value of antepartum fetal monitoring is in identifying those pregnancies that do not require immediate intervention and may be allowed to continue. Certainly, all pregnant women (regardless of risk status) should monitor fetal movement as part of their fetal surveillance. For patients at risk, a variety of testing schemes are available using combinations of the NST, CST and BPP. There are several reasons for using the NST as the primary testing method for those at risk. Even a small antenatal testing area can accommodate three or four FHR monitors, and a single antenatal testing nurse can perform several NSTs at a time. Because the BPP requires an ultrasound machine and a trained technician to perform, and because only one BPP can be done at a time, many obstetricians who do their own in-office fetal testing are unable to adopt BPP testing as their primary means of surveillance. Additionally, it is more economical to use the NST than the BPP for first-line testing. Assuming charges of $150 and $300 for the NST and BPP, respectively, and assuming that 20% of NSTs are nonreactive and require a BPP for second-line testing, the weekly cost of testing 100 patients is $21,000 for the NST and $37,500 for the BPP. This increase-in-testing cost must be balanced against the small improvement in perinatal mortality rates achieved with the use of the BPP. Because it must be performed in a hospital setting and takes an average of 90 minutes to complete, the CST is more expensive and time-consuming than either the NST or BPP and it is less frequently used as the primary method of fetal testing. In the past the CST was the most commonly used secondary test after a nonreactive NST, but use of the BPP in this situation has now become

    The goal of fetal monitoring in labour is the early detection of a hypoxic baby. There are a variety of tools and methods available for intermittent auscultation (IA) of the fetal heart rate (FHR). Low- and middle-income countries usually have only access to a Pinard/Laënnec or the use of a hand-held Doppler device. Currently, there is no robust evidence to guide clinical practice on the most effective IA tool to use, timing intervals and length of listening to the fetal heart for women during established labour. To evaluate the effectiveness of different tools for IA of the fetal heart rate during labour including frequency and duration of auscultation. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (19 September 2016), contacted experts and searched reference lists of retrieved articles. All published and unpublished randomised controlled trials (RCTs) or cluster-RCTs comparing different tools and methods used for intermittent fetal auscultation during labour for fetal and maternal well-being. Quasi-RCTs, and cross-over designs were not eligible for inclusion. All review authors independently assessed eligibility, extracted data and assessed risk of bias for each trial. Data were checked for accuracy. We included three studies (6241 women and 6241 babies), but only two studies are included in the meta-analyses (3242 women and 3242 babies). Both were judged as high risk for performance bias due to the inability to blind the participants and healthcare providers to the interventions. Evidence was graded as moderate to very low quality; the main reasons for downgrading were study design limitations and imprecision of effect estimates. Intermittent Electronic Fetal Monitoring (EFM) using Cardiotocography (CTG) with routine Pinard (one trial)There was no clear difference between groups in low Apgar scores at five minutes (reported as < six at five minutes after birth) (risk ratio (RR) 0.66, 95% confidence interval (CI) 0.24 to 1.83, 633

    Full Text Available A novel clinical decision support system is proposed in this paper for evaluating the fetal well-being from the cardiotocogram (CTG dataset through an Improved Adaptive Genetic Algorithm (IAGA and Extreme Learning Machine (ELM. IAGA employs a new scaling technique (called sigma scaling to avoid premature convergence and applies adaptive crossover and mutation techniques with masking concepts to enhance population diversity. Also, this search algorithm utilizes three different fitness functions (two single objective fitness functions and multi-objective fitness function to assess its performance. The classification results unfold that promising classification accuracy of 94% is obtained with an optimal feature subset using IAGA. Also, the classification results are compared with those of other Feature Reduction techniques to substantiate its exhaustive search towards the global optimum. Besides, five other benchmark datasets are used to gauge the strength of the proposed IAGA algorithm.

    Proposed by Frank Manning about 26 years ago, fetal biophysical profile has been incorporated to the propaedeutics of non-invasive fetal well being assessment in high-risk gestations. Despite the existence of other methods for assessing fetal vitality, as Doppler flowmetry, the biophysical profile continues to be important in estimating the risk of hypoxia and perinatal morbimortality for those fetuses. In the present article, the authors review the regulatory mechanisms of fetal biophysical activities, as well as physiological and pathological factors that interfere with them. The main objective of the study is to discuss the present and important aspects of the method, and the practical applications and interpretation of its findings, in order to help radiologists improve their knowledge in this specific area of fetal ultrasonography

    The criteria, which a modern obstetric department is based on, are to deliver serenely and naturally according to the mother's personal exigencies and preserving the child's right to his/her own safety. The attempt to offer the woman a natural place with respect for these principles has improved the knowledge about the physiologic changes of the female organism during labour and water birth. Our experience about water birth began on 1st of July 2000, the day of the inauguration of the new birth room of the maternal-infantile department of the hospital of Lavagna. We nursed 15 women during labour and water birth, 11 were multiparas, 4 were primiparas, the average age was 31-year-old. We used the existing criteria of maternal and fetal selection for the care of physiologic water birth with a low risk. Particularly, the fetal heart rate was monitored at least for 30 minutes before the immersion into water and then at scheduled intervals during labour. To this purpose we used a cardiotocograph provided with an ultrasound probe (with high density of crystals) and with a toco (with high sensitivity), both waterproof and wireless. In our sample the episiotomy was not performed and 3rd degree lacerations did not happen. The neonatal average weight was 3100 gr for the primiparas and 3040 gr for the multiparas, respectively. The Apgar measurement was never lower than 8. The average time of labour was 6 hours for the group of the primiparas and 4.25 hours for the multiparas, respectively. In conclusion the monitoring of fetal welfare during water labour does not substantially differ from the monitoring of traditional labour, but it requires specific equipments.

    The better understanding of fetal cardiovascular physiology coupled with improved technology for non-invasive study of the fetus now enable much more detailed assessment of fetal cardiac status than by heart rate alone. Even the latter, relatively simple, measurement contains much more information than was previously realized. It is also increasingly clear that no single measurement will provide the answer to all clinical dilemmas either on cardiac function or the welfare of the fetus as a whole. There are obvious clinical advantages in measuring several variables from one signal and the measurement of heart rate, heart rate variation and waveform from the ECG in labour is a potentially useful combination. Systolic time intervals or flow measurements could easily be added or used separately by combining real-time and Doppler ultrasound probes

    Pregnancy places exceptional demands on vitamin D and calcium availability; thus, their deficiencies during pregnancy threaten the woman and her fetus. Globally, vitamin D and other micronutrient deficiencies are common during pregnancy, especially in developing countries where pregnant women have less access to nutritional supplements. Vitamin D deficiency has been reported to be as high as 40% among pregnant women. As a pregnancy progresses, the requirements for vitamin D increase and thus, can worsen preexisting hypovitaminosis D. Consequently, hypovitaminosis D is increasingly associated with a higher incidence of fetal miscarriage, preeclampsia, gestational diabetes, bacterial vaginosis, and impaired fetal and childhood growth and development. This review explores the recent advances in the understanding of vitamin D and the pivotal role it plays in human reproduction, with an emphasis on pregnancy and its outcomes. Given the seriousness of the issue, there is a pressing need for clinicians to become aware of the risks associated with not identifying and correcting vitamin D deficiency. Identifying and correcting vitamin D deficiency, including safe exposure to sunlight, is particularly relevant for those who seek assistance with fertility issues or prenatal counseling, and those in the beginning of their pregnancy. The data point to a significant protective effects of vitamin D during pregnancy when the 25(OH)D serum level exceeds 30 ng/mL before pregnancy and during the first trimester and, sufficient levels are maintained throughout the pregnancy.

    Fetal growth restriction implies failure of a fetus to meet its growth potential and is associated with increased perinatal mortality and morbidity. Therefore, antenatal detection of fetal growth restriction is of major importance in an attempt to deliver improved clinical outcomes. The most commonly used approach towards screening for fetal growth restriction is by means of sonographic fetal weight estimation, to detect fetuses small for gestational age, defined by an estimated fetal weight <10th percentile for gestational age. However, the predictive accuracy of this approach is limited both by suboptimal detection rate (as it may overlook non-small-for-gestational-age growth-restricted fetuses) and by a high false-positive rate (as most small-for-gestational-age fetuses are not growth restricted). Here, we review 2 strategies that may improve the diagnostic accuracy of sonographic fetal biometry for fetal growth restriction. The first strategy involves serial ultrasound evaluations of fetal biometry. The information obtained through these serial assessments can be interpreted using several different approaches including fetal growth velocity, conditional percentiles, projection-based methods, and individualized growth assessment that can be viewed as mathematical techniques to quantify any decrease in estimated fetal weight percentile, a phenomenon that many care providers assess and monitor routinely in a qualitative manner. This strategy appears promising in high-risk pregnancies where it seems to improve the detection of growth-restricted fetuses at increased risk of adverse perinatal outcomes and, at the same time, decrease the risk of falsely diagnosing healthy constitutionally small-for-gestational-age fetuses as growth restricted. Further studies are needed to determine the utility of this strategy in low-risk pregnancies as well as to optimize its performance by determining the optimal timing and interval between exams. The second strategy refers to the

    The assessment and control of fetal exposure to radiation in the workplace is an issue that is complicated by both biological and political/social ramifications. As a result of the dramatic increase in the number of women employed as radiation workers during the past 10 years, many facilities using radioactive materials have instituted fetal protection programs with special requirements for female radiation workers. It is necessary, however, to ensure that any fetal protection program be developed in such a way as to be nondiscriminatory. A study has been initiated whose purpose is to balance the political/social and the biological ramifications associated with occupational protection of the developing embryo/fetus. Several considerations are involved in properly balancing these factors. These considerations include appropriate methods of declaring the pregnancy, training workers, controlling the dose to the embryo/fetus, measuring and calculating the dose to the embryo/fetus, and recording the pertinent information. Alternative strategies for handling these factors while ensuring maximum protection of the embryo/fetus and the rights and responsibilities of employees and employers are discussed

    The assessment of fetal growth represents a fundamental step towards the identification of the true growth restricted fetus that is associated to important perinatal morbidity and mortality. The possible ways of detecting abnormal fetal growth are taken into consideration in this review and their strong and weak points are discussed. An important debate still remains about how to discriminate between the physiologically small fetus that does not require special surveillance and the truly growth restricted fetus who is predisposed to perinatal complications, even if its parameters are above the cut-off limits established. In this article, we present the clinical tools of fetal growth assessment: Symphyseal-Fundal Height (SFH) measurement, the fetal ultrasound parameters widely taken into consideration when discussing fetal growth: Abdominal Circumference (AC) and Estimated Fetal Weight (EFW); several types of growth charts and their characteristics: populational growth charts, standard growth charts, individualized growth charts, customized growth charts and growth trajectories.

    Diffusion-weighted imaging (DWI) is important in the assessment of fetal brain development. However, it is clinically challenging and time-consuming to prepare neuromorphological examinations to assess real brain age and to detect abnormalities. To demonstrate that the Gini coefficient can be a simple, intuitive parameter for modelling fetal brain development. Postmortem fetal specimens(n = 28) were evaluated by diffusion-weighted imaging (DWI) on a 3-T MRI scanner using 60 directions, 0.7-mm isotropic voxels and b-values of 0, 150, 1,600 s/mm 2 . Constrained spherical deconvolution (CSD) was used as the local diffusion model. Fractional anisotropy (FA), apparent diffusion coefficient (ADC) and complexity (CX) maps were generated. CX was defined as a novel diffusion metric. On the basis of those three parameters, the Gini coefficient was calculated. Study of fetal brain development in postmortem specimens was feasible using DWI. The Gini coefficient could be calculated for the combination of the three diffusion parameters. This multidimensional Gini coefficient correlated well with age (Adjusted R 2 = 0.59) between the ages of 17 and 26 gestational weeks. We propose a new method that uses an economics concept, the Gini coefficient, to describe the whole brain with one simple and intuitive measure, which can be used to assess the brain's developmental state.

    334 ultrasound-cephalometries and 231 X-ray fetographies were performed for antenatal assessment of fetal maturity as well as for exact estimation of gestational age in women with unknown date of confinement. The accuracy of the predictions was compared. Ultrasound-cephalometry gave best results when performed until the 20th week of gestation. A correct prediction was obtained in 80.4% of cases. After the 20th week of gestation, the accuracy of prediction decreased. Radiology on the contrary gave optimal results at the end of pregnancy. A correct prediction of the date of confinement was obtained in 73.8% of cases, when the X-ray fetography was performed between the 37th and 40th week of gestation. At the end of gestation radiography should be performed, if there is a discrepancy between ultrasound and clinical estimation or if ultrasound-cephalometry was not carried out in early pregnancy - especially if induction of labour is necessary.

    Diffusion-weighted imaging (DWI) is important in the assessment of fetal brain development. However, it is clinically challenging and time-consuming to prepare neuromorphological examinations to assess real brain age and to detect abnormalities. To demonstrate that the Gini coefficient can be a simple, intuitive parameter for modelling fetal brain development. Postmortem fetal specimens(n = 28) were evaluated by diffusion-weighted imaging (DWI) on a 3-T MRI scanner using 60 directions, 0.7-mm isotropic voxels and b-values of 0, 150, 1,600 s/mm{sup 2}. Constrained spherical deconvolution (CSD) was used as the local diffusion model. Fractional anisotropy (FA), apparent diffusion coefficient (ADC) and complexity (CX) maps were generated. CX was defined as a novel diffusion metric. On the basis of those three parameters, the Gini coefficient was calculated. Study of fetal brain development in postmortem specimens was feasible using DWI. The Gini coefficient could be calculated for the combination of the three diffusion parameters. This multidimensional Gini coefficient correlated well with age (Adjusted R{sup 2} = 0.59) between the ages of 17 and 26 gestational weeks. We propose a new method that uses an economics concept, the Gini coefficient, to describe the whole brain with one simple and intuitive measure, which can be used to assess the brain's developmental state.

    Biokinetic data of selected radionuclide compounds from investigations in man and animal were taken from literature references with the purpose to provide a basis for a comparative assessment of fetal and adult radiation doses after intake or administration of radionuclides. The following ratios of fetal to adult doses were derived from human data: 0.5 for caesium 137 and total body, 2.3 for iron 59 and liver, 0.06 - 0.3 - 1.1 for iodine 131 and thyroid, and 0.1 - 0.3 for strontium 90 and bone. The ratios of activity concentrations in fetal and adult tissues are of considerable variability - up to three orders of magnitude. Further studies on fetal and adult biokinetics specifically designed for comparative dose assessment are indispensable. 106 refs.; 6 tabs

    The technical quality of prenatal US and fetal MRI has significantly improved during the last decade and allows an accurate diagnosis of bowel pathology prenatally. Accurate diagnosis of bowel pathology in utero is important for parental counseling and postnatal management. It is essential to recognize the US presentation of bowel pathology in the fetus in order to refer the patient for further evaluation or follow-up. Fetal MRI has been shown to offer some advantages over US for specific bowel abnormalities. In this paper, we review the normal appearance of the fetal bowel on US and MRI as well as the typical presentations of bowel pathologies. We discuss more specifically the importance of recognizing on fetal MRI the abnormalities of size and T1-weighted signal of the meconium-filled distal bowel. (orig.)

    We have presented that fetal surveillance may be enhanced by use of the fetal actocardiogram and by computerized processing of fetal motion as well as fetal B-mode ultrasound imaging. Ultrasonic Doppler fetal actogram is a sensitive and objective method for detecting and recording fetal movements. Computer processing of the actograph output signals enables powerful, detailed, and convenient analysis of fetal physiologic phenomena. The actocardiogram is a useful measurement tool not only in fetal behavioral studies but also in evaluation of fetal well-being. It reduces false-positive, nonreactive NST and false-positive sinusoidal FHR pattern. It is a valuable tool to predict fetal distress. The results of intrapartum fetal monitoring are further improved by the antepartum application of the actocardiogram. Quantified fetal motion analysis is a useful, objective evaluation of the embryo and fetus. This method allows monitoring of changes in fetal movement, as well as frequency, amplitude, and duration. Furthermore, quantification of fetal motion enables evaluation of fetal behavior states and how these states relate to other measurements, such as changes in FHR. Numeric analysis of both fetal actogram and fetal motion from B-mode images is a promising application in the correlation of fetal activity or behavior with other fetal physiologic measurements.

    Both traditional group practices and IPAs have felt the impact of changes brought about by managed care. Group practices need to ensure that their financial reporting and cost-accounting methods capture information that is key to decision making. An independent assessment of financial procedures helps identify any outstanding issues and maintain financial well-being. This assessment should be conducted at least quarterly so that potential problems can be resolved, income opportunities explored, and cost-saving measures adopted in a timely manner.

    An uncommon cause of cerebral ischemia in the territory of the posterior cerebral artery (PCA) is the combination of a fetal origin of the PCA and atherosclerotic disease in the internal carotid artery. This study compared the accuracy of CTA with DSA in the assessment of a fetal origin of the PCA. Patients in whom an intracranial DSA and CTA had been performed were reviewed. A fetal origin was defined as a normal-sized patent posterior communicating artery (PCoA) with hypoplasia or aplasia of the ipsilateral P1 segment. One hundred PCAs in 51 patients were analyzed. A fetal origin was present in ten vessels (10%, eight patients). CTA revealed all of them. CTA considered an additional three vessels as having a fetal origin, while DSA revealed a PCoA with the same diameter as the P1 segment of the PCA. Sensitivity and specificity of CTA in the assessment of a fetal origin could be estimated at 100 and 97%, respectively. Positive and negative predictive values were 77 and 100%, respectively. CTA can be considered a valid diagnostic tool for the assessment of a fetal origin of the PCA in patients with a cerebral ischemic event in the territory of the PCA. (orig.)

    1977-04-01

    Fetal heart rate profiles for periods up to 12 hours prior to delivery have been reviewed in 515 patients with a fetus at risk. Mechanisms other than fetal asphyxia will cause fetal heart rate decelerations, and fetal asphyxia may in some instances develop in the absence of total or late decelerations. However, an increasing incidence of total decelerations and late decelerations and particularly a marked pattern of total decelerations and late decelerations are of value in the prediction of fetal asphyxia. Fetal heart rate deceleration patterns can predict the probability of fetal asphyxia at the time of initial intervention, while a progression of fetal heart rate deceleration patterns in the individual fetus can be of assistance in the subsequent scheduling of serial acid-base assessments during labor.

    Neuromuscular blocking agents, used to arrest fetal motion for invasive intrauterine procedures, may cause temporary fetal heart rate changes. After 21 invasive procedures using either pancuronium bromide or vecuronium bromide, post-procedure fetal heart rate tracings were retrospectively compared. Pancuronium was associated with an increased fetal heart rate and decreased beat-to-beat variability for 2.5 hours after its use, whereas vecuronium caused no fetal heart rate changes. Vecuronium bromide offers advantages over pancuronium, because the decreased effect on the fetal heart allows better assessment of fetal well-being immediately following invasive intrauterine procedures.

  15. Selecting the Best Version of SHALOM to Assess Spiritual Well-Being

    Full Text Available This paper extends the reporting of contemporary use of the Spiritual Health and Life-Orientation Measure (SHALOM, which provides flexibility to researchers, enabling them to choose the version of the instrument that best suits the cohort under investigation. SHALOM was built on a solid theoretical foundation, provided by the Four Domains Model of Spiritual Health/Well-Being. It comprises 20 items that assess spiritual well-being, as reflected in the quality of relationships that each person has with themselves, others, the environment, and/or with God. Summary results are reported from 30 recent studies. SHALOM provides a unique form of assessment that is statistically stronger than just assessing lived experiences, in that spiritual harmony/dissonance is studied by comparing each person’s “lived experiences” with her/his “ideals” for spiritual well-being. SHALOM has been sought for use with hundreds of studies in 29 languages, in education, healthcare and wider community. A generic form of SHALOM was developed to expand the Transcendental domain to include more than God. However, recent studies have shown that relating with God is most important for spiritual well-being. The best version of SHALOM to assess spiritual well-being depends on the needs of the clients/participants and the project goals of the researcher. This will involve a selection between the original form of Spiritual Well-Being Questionnaire-SHALOM for comparison with other measures and investigation of characteristics influencing spiritual well-being; or the dissonance method for spiritual care; and either the original or the generic version of SHALOM for use with non-religious/secular participants.

  17. Can the anterior-posterior thigh diameter be used as an indicator for fetal age using two-dimensional sonography?

    Ismail, Saad Ramzi

    2008-01-01

    This study evaluated the usefulness and direct correlation of a simple new method of predicting fetal age by measurement of the anterior-posterior thigh diameter (APTD) in a normal 18 to 28 week pregnancies using two-dimensional sonography. Little published research exists in the area of fetal thigh biometry, specifically in the use of the anterior-posterior fetal thigh diameter (APTD). The only study I found was that of fetal thigh circumference. Continuing review of existing practices needs to be coupled with evaluation of alternate or additional methodology. Materials and methods: This was a quantitative prospective study of 55 patients in High Level General Hospital, Alberta, Canada. Anterior-posterior thigh diameters (APTD) were sonographically measured. The normal range for each week of pregnancy was determined five times for reliability. Results: Significant correlation was found between (APTD) and fetal age from simple line regression analysis, with 99.993% confidence intervals at each week from 18 to 28 weeks gestation. There was a correlation of 1 mm APTD per 1 week of fetal age. In addition R > 0.93, P < 0.001. The residual scatter plots confirmed the APTD validity. Conclusion: APTD is a reliable and valid method for assessing fetal age in a normal pregnancy and may be particularly useful when other parameters are unable to accurately predict fetal age. An accurate linear measurement of multiple fetal parameters allows a more complete profile of fetal growth and estimated date of delivery (EDD). APTD may also be useful in identifying fetal growth problems. All of the values of fetal age lie directly on the 'best-fit' regression line. Since the coefficient of determination (Rsq) is very high, this model is very effective

    Epidemiologic and experimental evidence suggests that adverse stimuli during critical periods in utero permanently alters organ structure and function and may have persistent consequences for the long-term health of the offspring. Fetal hypoxia, maternal malnutrition, or ventricular overloading are among the major adverse conditions that can compromise cardiovascular development in early life. With the heart as a central organ in fetal adaptive mechanisms, a deeper understanding of the fetal cardiovascular physiology and of the echocardiographic tools to assess both normal and stressed pregnancies would give precious information on fetal well-being and hopefully may help in early identification of special risk groups for cardiovascular diseases later in life. Assessment of cardiac function in the fetus represents an additional challenge when comparing to children and adults, requiring advanced training and a critical approach to properly acquire and interpret functional parameters. This review summarizes the basic fetal cardiovascular physiology and the main differences from the mature postnatal circulation, provides an overview of the particularities of echocardiographic evaluation in the fetus, and finally proposes an integrated view of in utero programming of cardiovascular diseases later in life, highlighting priorities for future clinical research.

    Screening for fetal aneuploidy during the first trimester using fetal nuchal translucency measurement and maternal serum free ss-hCG (ss-human chorionic gonadotropin) and PAPP-A (pregnancy associated plasma protein A) is commonly practised. An approach with a one stop clinic for assessment of risk for fetal anomalies, where pre-test counseling, blood test, ultrasound and post-test counseling is offered in one hour visit is described. Based on maternal age, biochemistry and fetal nuchal translucency measurement an estimated risk for fetal trisomies 13,18 and 21 is calculated. The main benefit of this approach in screening for fetal aneuploidy is the short turnaround time, with immediate results and a low screen positive rate. This approach leads to diagnosis of the majority (95%) of fetal aneuploidy cases. If screening is positive a diagnostic test is available with chorionic villous sampling or amniocentesis. In Iceland, fetal karyotyping is offered to women 35 years and older and performed during the second trimester, but by using this approach prenatal diagnosis can be moved to the first trimester and also offered to women of all ages. A screening approach with a series of steps from 10-15 weeks, including maternal blood test at 10 and again at 15 weeks, as well as an ultrasound and nuchal translucency measurement at 11-13 weeks, with integrated results at 15+ weeks has been proposed. This method offers even lower screen positive rate (1%) while detection rates of fetal aneuploides are high (>90%) but it requires four visits instead of one and the prolonged approach is likely to cause excess anxiety for the parents to be. If all women are to be offered prenatal sreening in the first trimester the structure of prenatal care in Iceland needs some modifications including scheduling the first prenatal visit at 8-10 weeks and teaching healthcare providers counseling regarding prenatal testing.

    Normal fetal lung development is a complex process influenced by mechanical and many biochemical factors. In addition to ultrasound, fetal magnetic resonance imaging (MRI) constitutes a new method to investigate this process in vivo during the second and third trimester. The techniques of MRI volumetry, assessment of signal intensities, and MRI spectroscopy of the fetal lung have been used to analyze this process and have already been applied clinically to identify abnormal fetal lung growth. Particularly in conditions such as oligohydramnios and congenital diaphragmatic hernia (CDH), pulmonary hypoplasia may be the cause of neonatal death. A precise diagnosis and quantification of compromised fetal lung development may improve post- and perinatal management. The main events in fetal lung development are reviewed and MR volumetric data from 106 normal fetuses, as well as different examples of pathological lung growth, are provided

    Full Text Available Intrauterine growth restriction (IUGR is a serious pregnancy complication with short- and long-term health consequences. The mechanisms underlying this condition are not well understood. Animal models are the basis for understanding the causes of IUGR and for developing useful therapeutic strategies. Here, we aimed to ascertain the in utero growth of fetuses from NK (natural killer cells/MC (mast cells-deficient mothers that give birth to growth-restricted pups and to determine the time point at which IUGR starts. We used high frequency ultrasound imaging to follow-up fetal and placenta size and employed Doppler measurements to document blood supply to the fetus in females that were deficient for NK cells and MCs. In mice lacking NKs and MCs, we observed significantly reduced implantation sizes from mid gestation onward, which was further associated with smaller placentas. Additionally, NK/MC-deficiency was associated with absent and reversed end diastolic flow in umbilical arteries of the fetuses and an increased systolic/diastolic ratio as well as an elevated resistance index. Together, our results indicate that NKs/MCs promote blood flow, placental growth, and subsequent fetal development. The results of this study offer new insights as to how fetal growth is affected in vivo in NK/MC-deficient mice, whose pups are growth restricted at birth. The use of IUGR models and modern technologies enabling the in vivo follow-up of fetal development are important tools for understanding mechanisms behind pregnancy complications that in the future may lead to the development of effective therapies.

    Fetal echocardiography is a well established sensitive tool to diagnose congenital heart disease (CHD) in utero. One of the determinants of effective utilization of fetal echocardiography is its awareness in the general population. The present hospital based study was undertaken to assess the awareness of the need for fetal echocardiography amongst Indian parents. One thousand one hundred and thirty eight consecutive parents who visited the pediatric cardiology outpatient department of a tertiary care centre over a period of two months were asked to fill up a questionnaire that included their demographic data, educational status, history of CHD in children, awareness of fetal echocardiography and source of information and timing of fetal echocardiogram if performed. The data was categorized and awareness was noted in different groups. The awareness in the study population was 2.2%. Awareness was found to be similar across the study population irrespective of the demographics and high risk status of the parents. The awareness of fetal echocardiography, an important tool in reducing the incidence of complex CHD, thereby impacting public health, is alarmingly low in the population studied. Appropriate action to increase awareness of fetal echocardiography needs to be looked into

    Ultrasonography is the preferred diagnostic imaging technique for intrauterine fetal examination. Nevertheless, circumstances sometimes dictate the use of other techniques in order to analyze fetal structures. The advent of ultra rapid magnetic resonance (MR) sequencing has led to the possibility of doing MR fetal studies, since images are obtained in an extradordiarily short time and are not affected by either maternal or fetal movements. It does not employ ionizing radiations, it provides high-contrast images and it can obtain such images in any plane of space without being influenced by either the child bearer's physical characteristics of fetal position. MR provides good quality images of most fetal organs. It is extremely useful in analysing distinct structures, as well as permitting an evaluation of cervical structures, lungs, diaphragms, intra-abdominal and retroperitoneal structures, and fetal extremities. It can also provide useful information regarding the placenta,umbilical cord, amniotic fluid and uterus. The objective of this work is to describe MR technique as applied to intrauterine fetal examination, and to illustrate normal fetal anatomy as manifested by MR and its applications. (Author) 42 refs

    2016-03-01

    Full Text Available Increasing evidence has demonstrated that in utero exposure to environmental chemicals may interfere with fetal development and increase the risk of disease and cancer development later in life. Ochratoxin A (OTA has been proven to induce diverse toxic effects including teratogenicity, carcinogenicity, immunotoxicity and potential endocrine disruption. Due to the continuous and widespread occurrence of OTA as a potential contaminant of staple foods, there is increasing concern of in utero exposure of fetus to this mycotoxin. In this study, maternal-fetal risk assessment of OTA during pregnancy was conducted using the benchmark dose approach for genotoxic carcinogens. The daily intake of OTA for Egyptian pregnant women was estimated based on their serum OTA level using the refined Klaassen equation for pregnancy. Fetal exposure level was also estimated based on the maternal data. Comparison between the estimated daily exposure and the negligible cancer risk intake (NCRI, and the calculation of margin of exposure (MOE implicated that OTA exposure from dietary intake would be of low health concern for this general subpopulation of Egyptian women. This subpopulation of pregnant women was generally estimated not to be in high-risk for toxicity induced by OTA.

    Ergonomics interventions have the potential to improve operational performance and employee well-being. We introduce a framework for ergonomics climate, the extent to which an organization emphasizes and supports the design and modification of work to maximize both performance and well-being outcomes. We assessed ergonomics climate at a large manufacturing facility twice during a two-year period. When the organization used ergonomics to promote performance and well-being equally, and at a high level, employees reported less work-related pain. A larger discrepancy between measures of operational performance and employee well-being was associated with increased reports of work-related pain. The direction of this discrepancy was not significantly related to work-related pain, such that it didn't matter which facet was valued more. The Ergonomics Climate Assessment can provide companies with a baseline assessment of the overall value placed on ergonomics and help prioritize areas for improving operational performance and employee well-being.

    A substantial body of research has investigated the effects of work on the psychological well-being of employees. However, there has been little assessment of the ways in which workplace factors (such as job demands, working conditions, inter-personal relations and workplace change) interact with personal factors (such as work-life balance, family circumstances, key personality traits or demographic characteristics) to affect psychological health. This article reports findings from a study which aimed to construct and test a comprehensive model of the influences on employee well-being within the UK National Health Service (NHS). The results show that psychological well-being is influenced by a complex array of personal, environmental and work factors. A key finding is that there are clear associations between workplace change and well-being and between work-life (im)balance and well-being. These effects appear to be independent of one another and therefore require separate attention from managers and employers.

    This work aims to investigate the impact of gestational age and fetal gender on fetal heart rate (FHR) tracings. Different linear and nonlinear parameters indicating correlation or complexity were used to study the influence of fetal age and gender on FHR tracings. The signals were recorded from 99 normal pregnant women in a singleton pregnancy at gestational ages from 28 to 40 weeks, before the onset of labor. There were 56 female fetuses and 43 male. Analysis of FHR shows that the means as well as measures of irregularity of FHR, such as approximate entropy and algorithmic complexity, decrease as gestation progresses. There were also indications that mutual information and multiscale entropy were lower in male fetuses in early pregnancy. Fetal age and gender seem to influence FHR tracings. Taking this into consideration would improve the interpretation of FHR monitoring.

    Fetal motility is a widely accepted indicator of the well-being of a fetus. In previous research, it has be shown that fetal motion (FM) is coherent with fetal heart rate accelerations and an indicator for active/rest cycles of the fetus. The most common approach for FM and fetal heart rate (FHR) assessment is by Doppler ultrasound (DUS). While DUS is the most common approach for studying the mechanical activities of the heart, noninvasive fetal electrocardiogram (ECG) and magnetocardiogram (MCG) recording and processing techniques have been considered as a possible competitor (or complement) for the DUS. In this study, a fully automatic and robust framework is proposed for the extraction, ranking and alignment of fetal QRS-complexes from noninvasive fetal ECG/MCG. Using notions from subspace tracking, two measures, namely the actogram and rotatogram, are defined for fetal motion tracking. The method is applied to four fetal ECG/MCG databases, including twin MCG recordings. By defining a novel measure of causality, it is shown that there is significant coherency and causal relationship between the actogram/rotatogram and FHR accelerations/decelerations. Using this measure, it is shown that in many cases, the actogram and rotatogram precede the FHR variations, which supports the idea of motion-induced FHR accelerations/decelerations for these cases and raises attention for the non-motion-induced FHR variations, which can be associated to the fetal central nervous system developments. The results of this study can lead to novel perspectives of the fetal sympathetic and parasympathetic brain systems and future requirements of fetal cardiac monitoring.

    Fetal growth restriction is a major determinant of perinatal morbidity and mortality. Screening for fetal growth restriction is a key element of prenatal care but it is recognized to be problematic. Screening using clinical risk assessment and targeting ultrasound to high-risk women is the standard of care in the United States and United Kingdom, but the approach is known to have low sensitivity. Systematic reviews of randomized controlled trials do not demonstrate any benefit from universal ultrasound screening for fetal growth restriction in the third trimester, but the evidence base is not strong. Implementation of universal ultrasound screening in low-risk women in France failed to reduce the risk of complications among small-for-gestational-age infants but did appear to cause iatrogenic harm to false positives. One strategy to making progress is to improve screening by developing more sensitive and specific tests with the key goal of differentiating between healthy small fetuses and those that are small through fetal growth restriction. As abnormal placentation is thought to be the major cause of fetal growth restriction, one approach is to combine fetal biometry with an indicator of placental dysfunction. In the past, these indicators were generally ultrasonic measurements, such as Doppler flow velocimetry of the uteroplacental circulation. However, another promising approach is to combine ultrasonic suspicion of small-for-gestational-age infant with a blood test indicating placental dysfunction. Thus far, much of the research on maternal serum biomarkers for fetal growth restriction has involved the secondary analysis of tests performed for other indications, such as fetal aneuploidies. An exemplar of this is pregnancy-associated plasma protein A. This blood test is performed primarily to assess the risk of Down syndrome, but women with low first-trimester levels are now serially scanned in later pregnancy due to associations with placental causes of

    Fetal infection with human parvovirus B19 (hParvo-B19) has been associated mainly with fetal anemia, although data regarding other fetal hematologic effects are limited. Our aim was to assess the rate and consequences of severe fetal thrombocytopenia after fetal hParvo-B19 infection. We conducted a retrospective study of pregnancies that were complicated by fetal hParvo-B19 infection that underwent fetal blood sampling (FBS). The characteristics and outcomes of fetuses with severe thrombocytopenia (B19 infection. A total of 37 pregnancies that were affected by fetal hParvo-B19 infection were identified. Of the 29 cases that underwent FBS and had information regarding fetal platelets, 11 cases (38%) were complicated by severe fetal thrombocytopenia. Severely thrombocytopenic fetuses were characterized by a lower hemoglobin concentration (2.6 ± 0.9 g/dL vs 5.5 ± 3.6 g/dL; P = .01), lower reticulocyte count (9.1% ± 2.8% vs 17.3% ± 10.6%; P = .02), and lower gestational age at the time of diagnosis (21.4 ± 3.1 wk vs 23.6 ± 2.2 wk; P = .03). Both the fetal death rate within 48 hours of FBS (27.3% vs 0%; P = .02) and the risk of prematurity (100.0% vs 13.3%; P B19 infection, can be further worsened by IUT, and may be associated with an increased risk of procedure-related fetal loss after either FBS or IUT.

    The monitoring of fetal activity during the last trimester of pregnancy has been proposed to be useful in assessing fetal welfare. The maternal perception of fetal activity was tested among 82 patients using real-time ultrasonography. All perceived fetal movements were visualized on the scanner and involved motion of the lower limbs. Conversely, 82% of all visualized motions of fetal limbs were perceived by the patients. All combined motions of fetal trunk with limbs were preceived by the patients and described as strong movements, whereas clusters of isolated, weak motions of the fetal limbs were less accurately perceived (56% accuracy). The number of fetal movements perceived during the 15-minute test period was significantly (p fetal motion was present (44 of 45 cases) than when it was absent (five of 10 cases). These findings reveal that perceived fetal motion is: (1) reliable; (2) related to the strength of lower limb motion; (3) increased with ruptured amniotic membranes; and (4) reassuring if considered to be active.

    Drug use by pregnant women in the first trimester of pregnancy and subsequent fetal exposure during early gestation can be assessed only by repetitive/systematic maternal blood/urine analysis or segmental hair analysis. No evidence of any relationship between maternal/fetal exposure during this specific period of gestation has been demonstrated to date in a human model. To clarify drugs toxicokinetics and transplacental passage during early pregnancy, the presence of the most widely used recreational drugs of abuse and metabolites was investigated in the proximal 4cm hair segments of women undergoing voluntary termination of pregnancy (n=280) during the 12th week of gestation and the results were compared to those from placenta and fetal tissue samples in order to verify whether maternal hair testing can reflect fetal exposure and, if so, to what extent. Hair, placenta and fetal remains were analyzed by validated gas chromatography mass spectrometry assays. Eighty one positive hair samples were identified: 60 were positive for cannabis (74.1%), 28 for cocaine (34.6%), 7 for opiates (8.6%), 3 for MDMA (3.7%) and 18.5% were positive for more than one drug. The positive hair test results were confirmed in placenta/fetal tissues in 10 cases out of 60 for cannabis (16. 7%); in 7 out of 28 for cocaine (25%); and none for the 6 opiates positive cases and 3 MDMA cases, respectively. Drugs/metabolites in hair of pregnant women can be used as biomarkers of past drug use (repetitive or sporadic), although the use is not always reflected in fetal/placental tissues. There are several possible hypotheses to explain the results: (1) the use occurred before the start of pregnancy, (2) past sporadic consumption which could be measured in hair but not in fetal and placental remains because of the narrow window of drug detection in placental/fetal tissues; (3) the sensitivity of the analytical methods was not high enough for the detection of the minute amount of drugs of abuse and

    Non-invasive foetal electrocardiography (NI-FECG) has the potential to provide more additional clinical information for detecting and diagnosing fetal diseases. We propose and demonstrate a deep learning approach for fetal QRS complex detection from raw NI-FECG signals by using a convolutional neural network (CNN) model. The main objective is to investigate whether reliable fetal QRS complex detection performance can still be obtained from features of single-channel NI-FECG signals, without canceling maternal ECG (MECG) signals. A deep learning method is proposed for recognizing fetal QRS complexes. Firstly, we collect data from set-a of the PhysioNet/computing in Cardiology Challenge database. The sample entropy method is used for signal quality assessment. Part of the bad quality signals is excluded in the further analysis. Secondly, in the proposed method, the features of raw NI-FECG signals are normalized before they are fed to a CNN classifier to perform fetal QRS complex detection. We use precision, recall, F-measure and accuracy as the evaluation metrics to assess the performance of fetal QRS complex detection. The proposed deep learning method can achieve relatively high precision (75.33%), recall (80.54%), and F-measure scores (77.85%) compared with three other well-known pattern classification methods, namely KNN, naive Bayes and SVM. the proposed deep learning method can attain reliable fetal QRS complex detection performance from the raw NI-FECG signals without canceling MECG signals. In addition, the influence of different activation functions and signal quality assessment on classification performance are evaluated, and results show that Relu outperforms the Sigmoid and Tanh on this particular task, and better classification performance is obtained with the signal quality assessment step in this study.

    Fetal cardiotocography is characterized by low specificity; therefore, in an attempt to ensure fetal well-being, fetal scalp blood sampling has been recommended by most obstetric societies in the case of a non-reassuring cardiotocography. The scientific agreement on the evidence for using fetal...... scalp blood sampling to decrease the rate of operative delivery for fetal distress is ambiguous. Based on the same studies, a Cochrane review states that fetal scalp blood sampling increases the rate of instrumental delivery while decreasing neonatal acidosis, whereas the National Institute of Health...... and Clinical Excellence guideline considers that fetal scalp blood sampling decreases instrumental delivery without differences in other outcome variables. The fetal scalp is supplied by vessels outside the skull below the level of the cranial vault, which is likely to be compressed during contractions...

  3. First and second trimester screening for fetal structural anomalies.

    Edwards, Lindsay; Hui, Lisa

    2018-04-01

    Fetal structural anomalies are found in up to 3% of all pregnancies and ultrasound-based screening has been an integral part of routine prenatal care for decades. The prenatal detection of fetal anomalies allows for optimal perinatal management, providing expectant parents with opportunities for additional imaging, genetic testing, and the provision of information regarding prognosis and management options. Approximately one-half of all major structural anomalies can now be detected in the first trimester, including acrania/anencephaly, abdominal wall defects, holoprosencephaly and cystic hygromata. Due to the ongoing development of some organ systems however, some anomalies will not be evident until later in the pregnancy. To this extent, the second trimester anatomy is recommended by professional societies as the standard investigation for the detection of fetal structural anomalies. The reported detection rates of structural anomalies vary according to the organ system being examined, and are also dependent upon factors such as the equipment settings and sonographer experience. Technological advances over the past two decades continue to support the role of ultrasound as the primary imaging modality in pregnancy, and the safety of ultrasound for the developing fetus is well established. With increasing capabilities and experience, detailed examination of the central nervous system and cardiovascular system is possible, with dedicated examinations such as the fetal neurosonogram and the fetal echocardiogram now widely performed in tertiary centers. Magnetic resonance imaging (MRI) is well recognized for its role in the assessment of fetal brain anomalies; other potential indications for fetal MRI include lung volume measurement (in cases of congenital diaphragmatic hernia), and pre-surgical planning prior to fetal spina bifida repair. When a major structural abnormality is detected prenatally, genetic testing with chromosomal microarray is recommended over

    Full Text Available Arthrogryposis multiplex congenital is a rare condition defined as contractures in multiple joints at birth due to disorders starting in fetal life. Its etiology is associated with many different conditions and in many instances remains unknown. The final common pathway to all of them is decreased fetal movement (fetal akinesia due to an abnormal intrauterine environment. Causes of decreased fetal movements may be neuropathic abnormalities, abnormalities of connective tissue or muscle, intrauterine vascular compromise, maternal diseases, and space limitations within the uterus. When the cause of arthrogryposis is space limitations in uterus, the most common etiology is oligohydramnios. The same can result from intrauterine tumours as fibroids, although to our knowledge there are only two papers reporting cases of fetal deformities related to uterine leiomyomas. We describe a well-documented exceptional case of arthrogryposis associated with the presence of a large uterine fibroid. It could illustrate the importance of a careful and appropriate assessment of uterine fibroids before and in the course of a pregnancy considering that they can cause both serious maternal and fetal complications.

    This study examined whether the type-5 phosphodiesterase inhibitor sildenafil citrate (Viagra; Pfizer, New York, NY) could increase uterine blood flow in intrauterine growth restriction (IUGR), thereby improving fetal oxygenation and well being. In fetal sheep, we induced IUGR at 105-110 days (0.7 gestation) using single umbilical artery ligation (SUAL). In SUAL and control animals, we measured uterine blood flow (UBF) and blood gases before and after sildenafil administration. SUAL fetuses were hypoxemic compared with controls. Following sildenafil, UBF was significantly decreased in both SUAL and control ewes for approximately 40 minutes. In response to sildenafil, pO(2) was decreased in SUAL and control fetuses and both groups displayed significant hypotension and tachycardia. At postmortem SUAL fetal body weight was significantly reduced by 23% compared with controls. Sildenafil does not improve UBF or fetal well being in SUAL-induced IUGR pregnancies and should be used with caution in IUGR and healthy pregnancies because of its detrimental effects on uteroplacental perfusion and on the fetus.

    The majority of research documenting the public health impacts of natural disasters focuses on the well-being of adults and their living children. Negative effects may also occur in the unborn, exposed to disaster stressors when critical organ systems are developing and when the consequences of exposure are large. We exploit spatial and temporal variation in hurricane behaviour as a quasi-experimental design to assess whether fetal death is dose-responsive in the extent of hurricane damage. Data on births and fetal deaths are merged with Parish-level housing wreckage data. Fetal outcomes are regressed on housing wreckage adjusting for the maternal, fetal, placental and other risk factors. The average causal effect of maternal exposure to hurricane destruction is captured by difference-in-differences analyses. The adjusted odds of fetal death are 1.40 (1.07-1.83) and 2.37 (1.684-3.327) times higher in parishes suffering 10-50% and >50% wreckage to housing stock, respectively. For every 1% increase in the destruction of housing stock, we observe a 1.7% (1.1-2.4%) increase in fetal death. Of the 410 officially recorded fetal deaths in these parishes, between 117 and 205 may be attributable to hurricane destruction and postdisaster disorder. The estimated fetal death toll is 17.4-30.6% of the human death toll. The destruction caused by Hurricanes Katrina and Rita imposed significant measurable losses in terms of fetal death. Postdisaster migratory dynamics suggest that the reported effects of maternal exposure to hurricane destruction on fetal death may be conservative. Published by the BMJ Publishing Group Limited.

    Complete atrioventricular block in fetuses is known to be mostly associated with autoimmune disease and can be irreversible if no steroids treatment is provided. Conventional methods used in clinical practice for diagnosing fetal arrhythmia are limited since they do not reflect the primary electrophysiological conduction processes that take place in the myocardium. The non-invasive fetal electrocardiogram has the potential to better support fetal arrhythmias diagnosis through the continuous analysis of the beat to beat variation of the fetal heart rate and morphological analysis of the PQRST complex. We present two retrospective case reports on which atrioventricular block diagnosis could have been supported by the non-invasive fetal electrocardiogram. The two cases comprised a 22-year-old pregnant woman with the gestational age of 31 weeks and a 25-year-old pregnant woman with the gestational age of 41 weeks. Both women were admitted to the Department of Maternal and Fetal Medicine at the Kyiv and Kharkiv municipal perinatal clinics. Patients were observed using standard fetal monitoring methods as well as the non-invasive fetal electrocardiogram. The non-invasive fetal electrocardiographic recordings were analyzed retrospectively, where it is possible to identify the presence of the atrioventricular block. This study demonstrates, for the first time, the feasibility of the non-invasive fetal electrocardiogram as a supplementary method to diagnose of the fetal atrioventricular block. Combined with current fetal monitoring techniques, non-invasive fetal electrocardiography could support clinical decisions.

    2006-01-01

    Specialised instruments have been developed to aid the care of the fetus and the newborn baby. Miniature sensors using optical, electrical, chemical, mechanical and magnetic principles have been produced for capturing key measurands. These include temperature, pressure, flow and dimension, as well as several specific molecules such as glucose, oxygen and carbon dioxide. During pregnancy ultrasound imaging and blood flow techniques provide valuable information concerning fetal abnormalities, fetal growth, fetal breathing and fetal heart rate. Signal processing and pattern recognition can be useful for deriving indicators of fetal distress and clinical status, based on biopotentials as well as ultrasound signals. Fetal pH measurement is a critical requirement during labour and delivery. The intensive care of ill preterm babies involves provision of an optimal thermal environment and respiratory support. Monitoring of blood gas and acid-base status is essential, and this involves both blood sampling for in vitro analysis as well as the use of invasive or non-invasive sensors. For the future it will be vital that the technologies used are subjected to controlled trials to establish benefit or otherwise

    To assess differences in fetal behavior in both normal fetuses and fetuses with cerebral ventriculomegaly (VM). In a period of eighteen months, in a longitudinal prospective cohort study, Kurjak Antenatal NeuorogicalTest (KANET) was applied to assess fetal behavior in both normal pregnancies and pregnancies with cerebral VM using four-dimensional ultrasound (4D US). According to the degree of enlargement of the ventricles, VM was divided into three groups: mild, moderate and severe. Moreover fetuses with isolated VM were separated from those with additional abnormalities. According to the KANET, fetuses with scores ≥ 14 were considered normal, those with scores 6-13 borderline and abnormal if the score was ≤ 5. Differences between two groups were examined by Fisher's exact test. Differences within the subgroups were examined by Kruskal-Wallis test and contingency table test. KANET scores in normal pregnancies and pregnancies with VM showed statistically significant differences. Most of the abnormal KANET scores as well as most of the borderline-scores were found among the fetuses with severe VM associated with additional abnormalities. There were no statistically significant differences between the control group and the groups with isolated and mild and /or moderate VM. Evaluation of the fetal behavior in fetuses with cerebral VM using KANET test has the potential to detect fetuses with abnormal behavior, and to add the dimension of CNS function to the morphological criteria of VM. Long-term postnatal neurodevelopmental follow-up should confirm the data from prenatal investigation of fetal behavior.

    Monitoring procedures are the basis to evaluate the clinical state of patients and to assess changes in their conditions, thus providing necessary interventions in time. Both these two objectives can be achieved by integrating technological development with methodological tools, thus allowing accurate classification and extraction of useful diagnostic information. The paper is focused on monitoring procedures applied to fetal heart rate variability (FHRV) signals, collected during pregnancy, in order to assess fetal well-being. The use of linear time and frequency techniques as well as the computation of non linear indices can contribute to enhancing the diagnostic power and reliability of fetal monitoring. The paper shows how advanced signal processing approaches can contribute to developing new diagnostic and classification indices. Their usefulness is evaluated by comparing two selected populations: normal fetuses and intra uterine growth restricted (IUGR) fetuses. Results show that the computation of different indices on FHRV signals, either linear and nonlinear, gives helpful indications to describe pathophysiological mechanisms involved in the cardiovascular and neural system controlling the fetal heart. As a further contribution, the paper briefly describes how the introduction of wearable systems for fetal ECG recording could provide new technological solutions improving the quality and usability of prenatal monitoring.

  11. Gratitude and Well Being

    2010-01-01

    The word “gratitude” has a number of different meanings, depending on the context. However, a practical clinical definition is as follows—gratitude is the appreciation of what is valuable and meaningful to oneself; it is a general state of thankfulness and/or appreciation. The majority of empirical studies indicate that there is an association between gratitude and a sense of overall well being. However, there are several studies that indicate potential nuances in the relationship between gratitude and well being as well as studies with negative findings. In terms of assessing gratitude, numerous assessment measures are available. From a clinical perspective, there are suggested therapeutic exercises and techniques to enhance gratitude, and they appear relatively simple and easy to integrate into psychotherapy practice. However, the therapeutic efficacy of these techniques remains largely unknown. Only future research will clarify the many questions around assessment, potential benefits, and enhancement of gratitude. PMID:21191529

    Hypoxaemia during labour can alter the shape of the fetal electrocardiogram (ECG) waveform, notably the relation of the PR to RR intervals, and elevation or depression of the ST segment. Technical systems have therefore been developed to monitor the fetal ECG during labour as an adjunct to continuous electronic fetal heart rate monitoring with the aim of improving fetal outcome and minimising unnecessary obstetric interference. To compare the effects of analysis of fetal ECG waveforms during labour with alternative methods of fetal monitoring. The Cochrane Pregnancy and Childbirth Group's Trials Register (latest search 23 September 2015) and reference lists of retrieved studies. Randomised trials comparing fetal ECG waveform analysis with alternative methods of fetal monitoring during labour. One review author independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. One review author assessed the quality of the evidence using the GRADE approach. Seven trials (27,403 women) were included: six trials of ST waveform analysis (26,446 women) and one trial of PR interval analysis (957 women). The trials were generally at low risk of bias for most domains and the quality of evidence for ST waveform analysis trials was graded moderate to high. In comparison to continuous electronic fetal heart rate monitoring alone, the use of adjunctive ST waveform analysis made no obvious difference to primary outcomes: births by caesarean section (risk ratio (RR) 1.02, 95% confidence interval (CI) 0.96 to 1.08; six trials, 26,446 women; high quality evidence); the number of babies with severe metabolic acidosis at birth (cord arterial pH less than 7.05 and base deficit greater than 12 mmol/L) (average RR 0.72, 95% CI 0.43 to 1.20; six trials, 25,682 babies; moderate quality evidence); or babies with neonatal encephalopathy (RR 0.61, 95% CI 0.30 to 1.22; six trials, 26,410 babies; high quality evidence). There were, however, on average

    Evidence for a role of vitamin D in maintaining normal glucose homeostasis is inconclusive. We sought to clarify the relationship between maternal and fetal insulin resistance and vitamin D status. This is a prospective cohort study of 60 caucasian pregnant women. Concentrations of 25-hydroxyvitamin D (25-OHD), glucose, insulin, and leptin were measured in early pregnancy and at 28 weeks. Ultrasound at 34 weeks assessed fetal anthropometry including abdominal wall width, a marker of fetal adiposity. At delivery birth weight was recorded and fetal 25-OHD, glucose, C-peptide, and leptin measured in cord blood. Insulin resistance was calculated using the Homeostasis Model Assessment (HOMA) equation. We found that those with lower 25-OHD in early pregnancy had higher HOMA indices at 28 weeks, (r = -.32, P = .02). No significant relationship existed between maternal or fetal leptin and 25-OHD, or between maternal or fetal 25-OHD and fetal anthropometry or birth weight. The incidence of vitamin D deficiency was high at each time point (15%-45%). These findings lend support to routine antenatal supplementation with vitamin D in at risk populations.

    Full Text Available OBJECTIVE: Development and validation of the Eating Disorders Section of the Development and Well-Being Assessment (DAWBA. It is a package of questionnaires, interviews and evaluation techniques, designed to generate DSM-IV and ICD-10 based diagnoses of anorexia, bulimia nervosa and the respective partial syndromes in epidemiological studies, in subjects who are 7 to 17 years old. The parents are interviewed in all cases, as are young people aged 11 or more. METHODS: 174 girls, divided into three groups, were assessed with the Eating Disorders Section of the Development and Well-Being Assessment: 48 with eating disorders, 55 clinical controls (with depression, obsessive-compulsive disorder or gastrointestinal disease and 71 community controls. The sensitivity, specificity and predictive values of the assessment were investigated by comparing the Development and Well-Being Assessment diagnoses with independent psychiatric diagnoses. The test-retest reliability was investigated by reapplying the measure on 55 subjects after 2 or 3 weeks. RESULTS: For the detection of any DSM-IV and ICD-10 eating disorder, the final Development and Well-Being Assessment diagnosis had a sensitivity of 100%, specificity of 94%, positive predictive value of 88%, and a negative predictive value of 100%; there was 95% agreement between the initial and repeat diagnoses (a kappa of 0.81. CONCLUSION: The Eating Disorders Section of the Development and Well-Being Assessment has suitable psychometric properties for use in clinical and epidemiological studies.OBJETIVOS: Desenvolvimento e validação da Sessão de Transtornos Alimentares do Development and Well-Being Assessment (DAWBA.

    The purpose of this study was to evaluate the feasibility of imaging the fetal heart with a balanced steady-state free precession MRI sequence along the body and cardiac axes after inadequate echocardiography. After technically inadequate echocardiography, MRI was performed on 20 fetuses (mean gestational age, 24 weeks; range, 18-32 weeks) at risk of congenital heart disease. MRI was attempted along the three fetal body planes (n = 20) and cardiac axes (n = 3) without fetal sedation. The images were analyzed with an anatomic segmental approach. Each feature was classified as well visualized or poorly or not visualized. In each group, the Student's t test was used to assess the relation between visibility of fetal cardiac features and gestational age. Imaging was possible along the fetal body and cardiac axes. In the axial plane, a balanced four-chamber view was obtained in all fetuses, enabling evaluation of heart position, axis, chambers, and interventricular septum. The left and right ventricular outflow tracts were well visualized in 12 (60%) and nine (45%) of the fetuses, respectively; the three-vessel view was obtained in 10 fetuses (50%). With the combination of sagittal and coronal views, both ventricular outflow tracts were assessed in all fetuses. The superior and inferior venae cavae were identified in all fetuses, and at least one pulmonary vein was visualized in 17 fetuses (85%). There were no statistically significant differences between gestational age and lack of visualization of a cardiac feature that was attributed to fetal motion. MRI of the fetal heart with a steady-state free precession sequence in multiple planes and image analysis with an anatomic segmental approach to congenital heart disease are possible in situations that limit echocardiography.

    Prenatal diagnosis of congenital heart disease is now well established for a wide range of cardiac anomalies. Diagnosis of congenital heart disease during fetal life not only identifies the cardiac lesion but may also lead to detection of associated abnormalities. This information allows a detailed discussion of the prognosis with parents. For continuing pregnancies, appropriate preparation can be made to optimize the postnatal outcome. Reduced morbidity and mortality, following antenatal diagnosis, has been reported for coarctation of the aorta, hypoplastic left heart syndrome, and transposition of the great arteries. With regard to screening policy, most affected fetuses are in the “low risk” population, emphasizing the importance of appropriate training for those who undertake such obstetric anomaly scans. As a minimum, the four chamber view of the fetal heart should be incorporated into midtrimester anomaly scans, and where feasible, views of the outflow tracts should also be included, to increase the diagnostic yield. Newer screening techniques, such as measurement of nuchal translucency, may contribute to identification of fetuses at high risk for congenital heart disease and prompt referral for detailed cardiac assessment

    Cardiotocography (CTG) records changes in the fetal heart rate and their temporal relationship to uterine contractions. The aim is to identify babies who may be short of oxygen (hypoxic) to guide additional assessments of fetal wellbeing, or determine if the baby needs to be delivered by caesarean section or instrumental vaginal birth. This is an update of a review previously published in 2013, 2006 and 2001. To evaluate the effectiveness and safety of continuous cardiotocography when used as a method to monitor fetal wellbeing during labour. We searched the Cochrane Pregnancy and Childbirth Group Trials Register (30 November 2016) and reference lists of retrieved studies. Randomised and quasi-randomised controlled trials involving a comparison of continuous cardiotocography (with and without fetal blood sampling) with no fetal monitoring, intermittent auscultation intermittent cardiotocography. Two review authors independently assessed study eligibility, quality and extracted data from included studies. Data were checked for accuracy. We included 13 trials involving over 37,000 women. No new studies were included in this update.One trial (4044 women) compared continuous CTG with intermittent CTG, all other trials compared continuous CTG with intermittent auscultation. No data were found comparing no fetal monitoring with continuous CTG. Overall, methodological quality was mixed. All included studies were at high risk of performance bias, unclear or high risk of detection bias, and unclear risk of reporting bias. Only two trials were assessed at high methodological quality.Compared with intermittent auscultation, continuous cardiotocography showed no significant improvement in overall perinatal death rate (risk ratio (RR) 0.86, 95% confidence interval (CI) 0.59 to 1.23, N = 33,513, 11 trials, low quality evidence), but was associated with halving neonatal seizure rates (RR 0.50, 95% CI 0.31 to 0.80, N = 32,386, 9 trials, moderate quality evidence).

    Full Text Available Abstract Background The appropriateness of an individual's intra uterine growth is now considered an important determinant of both short and long term outcomes, yet currently used measures have several shortcomings. This study demonstrates a method of assessing appropriateness of intrauterine growth based on the estimation of each individual's optimal newborn dimensions from routinely available perinatal data. Appropriateness of growth can then be inferred from the ratio of the value of the observed dimension to that of the optimal dimension. Methods Fractional polynomial regression models including terms for non-pathological determinants of fetal size (gestational duration, fetal gender and maternal height, age and parity were used to predict birth weight, birth length and head circumference from a population without any major risk factors for sub-optimal intra-uterine growth. This population was selected from a total population of all singleton, Caucasian births in Western Australia 1998–2002. Births were excluded if the pregnancy was exposed to factors known to influence fetal growth pathologically. The values predicted by these models were treated as the optimal values, given infant gender, gestational age, maternal height, parity, and age. Results The selected sample (N = 62,746 comprised 60.5% of the total Caucasian singleton birth cohort. Equations are presented that predict optimal birth weight, birth length and head circumference given gestational duration, fetal gender, maternal height, age and parity. The best fitting models explained 40.5% of variance for birth weight, 32.2% for birth length, and 25.2% for head circumference at birth. Conclusion Proportion of optimal birth weight (length or head circumference provides a method of assessing appropriateness of intrauterine growth that is less dependent on the health of the reference population or the quality of their morphometric data than is percentile position on a birth weight

    Human Wharton's jelly-derived mesenchymal stromal cells (hWJMSCs) are possibly the most suitable allogeneic cell source for stromal cell therapy and tissue engineering applications because of their hypo-immunogenic and non-tumorigenic properties, easy availability and minimal ethical concerns. Furthermore, hWJMSCs possess unique properties of both adult mesenchymal stromal cells and embryonic stromal cells. The human umbilical cord (UC) is approximately 50-60 cm long and the existing studies in the literature have not provided information on which segment of the UC was studied. In this study, hWJMSCs derived from three anatomical segments of the UC are compared. Three segments of the whole UC, each 3 cm in length, were identified anatomically as the maternal, middle and fetal segments. The hWJMSCs from the different segments were analyzed via trypan blue exclusion assay to determine the growth kinetics and cell viability, flow cytometry for immunophenotyping and immunofluorescence and reverse transcriptase polymerase chain reaction (RT-PCR) for expression of stromal cell transcriptional factors. Furthermore, the trilineage differentiation potential (osteogenic, adipogenic and chondrogenic) of these cells was also assessed. hWJMSCs isolated from the maternal and fetal segments displayed greater viability and possessed a significantly higher proliferation rate compared with cells from the middle segment. Immunophenotyping revealed that hWJMSCs derived from all three segments expressed the MSC markers CD105, CD73, CD90, CD44, CD13 and CD29, as well as HLA-ABC and HLA-DR, but were negative for hematopoietic markers CD14, CD34 and CD45. Analysis of the embryonic markers showed that all three segments expressed Nanog and Oct 3/4, but only the maternal and fetal segments expressed SSEA 4 and TRA-160. Cells from all three segments were able to differentiate into chondrogenic, osteogenic and adipogenic lineages with the middle segments showing much lower differentiation

    Full Text Available Alternative methods to assess ventricular diastolic function in the fetus are proposed. Fetal myocardial hypertrophy in maternal diabetes was used as a model of decreased left ventricular compliance (LVC, and fetal respiratory movements as a model of increased LVC. Comparison of three groups of fetuses showed that, in 10 fetuses of diabetic mothers (FDM with septal hypertrophy (SH, the mean excursion index of the septum primum (EISP (ratio between the linear excursion of the flap valve and the left atrial diameter was 0.36 ± 0.09, in 8 FDM without SH it was 0.51 ± 0.09 (P = 0.001, and in the 8 normal control fetuses (NCF it was 0.49 ± 0.12 (P = 0.003. In another study, 28 fetuses in apnea had a mean EISP of 0.39 ± 0.05 which increased to 0.57 ± 0.07 during respiration (P < 0.001. These two studies showed that the mobility of the septum primum was reduced when LVC was decreased and was increased when LVC was enhanced. Mean pulmonary vein pulsatility was higher in 14 FDM (1.83 ± 1.21 than in 26 NCF (1.02 ± 0.31; P = 0.02. In the same fetuses, mean left atrial shortening was decreased (0.40 ± 0.11 in relation to NCF (0.51 ± 0.09; P = 0.011. These results suggest that FDM may have a higher preload than normal controls, probably as a result of increased myocardial mass and LV hypertrophy. Prenatal assessment of LV diastolic function by fetal echocardiography should include analysis of septum primum mobility, pulmonary vein pulsatility, and left atrial shortening.

This condition can have a critical effect on pregnancy outcome, as well as on fetal growth and neurological development. The purpose of this Review is to clarify if and how fetal goitrous hypothyroidism can...... be prevented, and how to react when prevention has failed. Understanding the importance of pregnancy-related changes in maternal thyroid status when treating a pregnant woman is crucial to preventing fetal goitrous hypothyroidism. Maternal levels of free T(4) are the most consistent indication of maternal...... and fetal thyroid status. In patients with fetal goitrous hypothyroidism, intra-amniotic levothyroxine injections improve fetal outcome.

    The evaluation of cerebellar growth in the fetal period forms a part of a widely used examination to identify any features of abnormalities in early stages of human development. It is well known that the development of anatomical structures, including the cerebellum, does not always follow a linear model of growth. The aim of the study was to analyse a variety of mathematical models of human cerebellar development in fetal life to determine their adequacy. The study comprised 101 fetuses (48 males and 53 females) between the 15th and 28th weeks of fetal life. The cerebellum was exposed and measurements of the vermis and hemispheres were performed, together with statistical analyses. The mathematical model parameters of fetal growth were assessed for crown-rump length (CRL) increases, transverse cerebellar diameter and ventrodorsal dimensions of the cerebellar vermis in the transverse plane, and rostrocaudal dimensions of the cerebellar vermis and hemispheres in the frontal plane. A variety of mathematical models were applied, including linear and non-linear functions. Taking into consideration the variance between models and measurements, as well as correlation parameters, the exponential and Gompertz models proved to be the most suitable for modelling cerebellar growth in the second and third trimesters of pregnancy. However, the linear model gave a satisfactory approximation of cerebellar growth, especially in older fetuses. The proposed models of fetal cerebellar growth constructed on the basis of anatomical examination and objective mathematical calculations could be useful in the estimation of fetal development. © 2018 Anatomical Society.

    Acquired fetal brain damage is suspected in cases of destruction of previously normally formed tissue, the primary cause of which is hypoxia. Fetal brain damage may occur as a consequence of acute or chronic maternal diseases, with acute diseases causing impairment of oxygen delivery to the fetal brain, and chronic diseases interfering with normal, placental development. Infections, metabolic diseases, feto-fetal transfusion syndrome, toxic agents, mechanical traumatic events, iatrogenic accidents, and space-occupying lesions may also qualify as pathologic conditions that initiate intrauterine brain damage. MR manifestations of acute fetal brain injury (such as hemorrhage or acute ischemic lesions) can easily be recognized, as they are hardly different from postnatal lesions. The availability of diffusion-weighted sequences enhances the sensitivity in recognizing acute ischemic lesions. Recent hemorrhages are usually readily depicted on T2 (*) sequences, where they display hypointense signals. Chronic fetal brain injury may be characterized by nonspecific changes that must be attributable to the presence of an acquired cerebral pathology. The workup in suspected acquired fetal brain injury also includes the assessment of extra-CNS organs that may be affected by an underlying pathology. Finally, the placenta, as the organ that mediates oxygen delivery from the maternal circulation to the fetus, must be examined on MR images

    2017-12-01

    Full Text Available The fetal Doppler Ultrasound (DUS is commonly used for monitoring fetal heart rate and can also be used for identifying the event timings of fetal cardiac valve motions. In early-stage fetuses, the detected Doppler signal suffers from noise and signal loss due to the fetal movements and changing fetal location during the measurement procedure. The fetal cardiac intervals, which can be estimated by measuring the fetal cardiac event timings, are the most important markers of fetal development and well-being. To advance DUS-based fetal monitoring methods, several powerful and well-advanced signal processing and machine learning methods have recently been developed. This review provides an overview of the existing techniques used in fetal cardiac activity monitoring and a comprehensive survey on fetal cardiac Doppler signal processing frameworks. The review is structured with a focus on their shortcomings and advantages, which helps in understanding fetal Doppler cardiogram signal processing methods and the related Doppler signal analysis procedures by providing valuable clinical information. Finally, a set of recommendations are suggested for future research directions and the use of fetal cardiac Doppler signal analysis, processing, and modeling to address the underlying challenges.

    This study was conducted to establish representative curves that allow evaluation of fetal growth and estimation of gestational age from measurement of fetal structures by ultrasound in Malayan tapirs (Tapirus indicus). Three pregnancies (i.e. 3 fetuses) were examined in one female Malayan tapir. Transabdominal ultrasonographic examination was performed without anesthesia from 79 ± 8 days to 281 ± 48 days (mean ± S.D.) post mating. To assess fetal growth attempts were made to measure biparietal diameter (BPD), head length (HL), thorax diameter A (TDA), thorax height A (THA), thorax diameter B (TDB), thorax height B (THB), abdomen diameter (AD), abdomen height (AH), humerus length (HUL) and Crown rump length (CRL). The value of each parameter as an estimator of gestational age was assessed by ease of observation and the length of time the parameter was measurable throughout gestation. The most precise predictors for gestational age in this study were BPD and CRL (weeks 10-20 of gestation), as well as AD and AH (weeks 14-43 of gestation). The parameters TDB, THB and HUL (weeks 15-41 of gestation) gave almost as good predictions. Fetal viability was assessed by identifying a fetal heartbeat and movement. All pregnancies resulted in normal deliveries and healthy offspring. The ultrasound examination was well tolerated by the female. The gestation lengths (399 ± 3 days) were within reported ranges. The serial transabdominal ultrasound, without the need for anesthesia, was an effective method to evaluate fetal growth, development and well being in a Malayan tapir. © 2014 Wiley Periodicals, Inc.

    Although all the imaging studies in this pictorial essay were done for maternal rather than fetal indications, fetal anatomy was well visualized. However, when scans are undertaken for fetal indications, fetal motion in between scout views and imaging sequences may make specific image planes difficult to obtain. Of the different techniques described in this review, we preferred the HASTE technique and use it almost exclusively for scanning pregnant patients. The T2-weighting is ideal for delineating fetal organs. Also, the HASTE technique allows images to be obtained in 430 msec, limiting artifacts arising from maternal and fetal motion. MR imaging should play a more important role in evaluating equivocal sonographic cases as fast scanning techniques are more widely used. Obstetric MR imaging no longer will be limited by fetal motion artifacts. When complex anatomy requires definition in a complicated pregnant patient, MR imaging should be considered as a useful adjunct to sonography.

    USG performed with a high-end machine, using a good cine-loop facility is extremely helpful in the diagnosis of fetal cardiac anomalies. In fetal echocardiography, the four-chamber view and the outflow-tract view are used to diagnose cardiac anomalies. The most important objective during a targeted anomaly scan is to identify those cases that need a dedicated fetal echocardiogram. Associated truncal and chromosomal anomalies need to be identified. This review shows how fetal echocardiography, apart from identifying structural defects in the fetal heart, can be used to look at rhythm abnormalities and other functional aspects of the fetal heart

    Ultrasonography is the method of choice for prenatal malformation screening, but it does not always provide sufficient information for correct diagnosis or adequate abnormality evaluation. Fetal MRI is increasingly being used to complete sonographic findings. It was initially used for evaluation of cerebral abnormalities but is increasingly being applied to other fetal areas. In vivo investigation of fetal brain maturation has been enhanced by MRI. An adequate analysis of fetal chest and abdomen can be achieved with fast T2-, T1-weighted and diffusion-weighted imaging (DWI). The advantages include the great field of view and the excellent soft tissue contrast. This allows correct diagnosis of congenital diaphragmatic hernia and evaluation of the consequences on pulmonary growth. Other pulmonary malformations, such as cystic adenomatoid malformation, sequestration and brochogenic cysts, can also be easily identified. Renal position can be quickly determined using DWI sequences and renal agenesia can be easily diagnosed with only one sequence. Prenatal MRI is virtually as effective as postnatal examination, dispenses with transport of a potentially very ill newborn, and provides logistic advantages. Therefore, prenatal MRI is useful for adequate postnatal treatment of newborns with malformations. (orig.)

  11. Fetal functional brain age assessed from universal developmental indices obtained from neuro-vegetative activity patterns.

    Dirk Hoyer

    Full Text Available Fetal brain development involves the development of the neuro-vegetative (autonomic control that is mediated by the autonomic nervous system (ANS. Disturbances of the fetal brain development have implications for diseases in later postnatal life. In that context, the fetal functional brain age can be altered. Universal principles of developmental biology applied to patterns of autonomic control may allow a functional age assessment. The work aims at the development of a fetal autonomic brain age score (fABAS based on heart rate patterns. We analysed n = 113 recordings in quiet sleep, n = 286 in active sleep, and n = 29 in active awakeness from normals. We estimated fABAS from magnetocardiographic recordings (21.4-40.3 weeks of gestation preclassified in quiet sleep (n = 113, 63 females and active sleep (n = 286, 145 females state by cross-validated multivariate linear regression models in a cross-sectional study. According to universal system developmental principles, we included indices that address increasing fluctuation range, increasing complexity, and pattern formation (skewness, power spectral ratio VLF/LF, pNN5. The resulting models constituted fABAS. fABAS explained 66/63% (coefficient of determination R(2 of training and validation set of the variance by age in quiet, while 51/50% in active sleep. By means of a logistic regression model using fluctuation range and fetal age, quiet and active sleep were automatically reclassified (94.3/93.1% correct classifications. We did not find relevant gender differences. We conclude that functional brain age can be assessed based on universal developmental indices obtained from autonomic control patterns. fABAS reflect normal complex functional brain maturation. The presented normative data are supplemented by an explorative study of 19 fetuses compromised by intrauterine growth restriction. We observed a shift in the state distribution towards active awakeness. The lower WGA

    Student well-being has mostly been studied as an individual phenomenon with little research investigating how the well-being of one's classmates could influence a student's well-being. The aim of the current study was to examine how the aggregate well-being of students who comprise a class could predict students' subsequent well-being (Time 2 well-being) after controlling for the effects of prior well-being (Time 1 well-being) as well as key demographic variables such as gender and age. Two studies among Filipino secondary school students were conducted. In Study 1, 788 students from 21 classes participated; in Study 2, 404 students from 10 classes participated. For Study 1, questionnaires assessing students' life satisfaction, positive affect and negative affect were administered twice seven months apart. For Study 2, the well-being questionnaires were administered twice, three months apart. Hierarchical linear modeling was used with level 1 (Time 1 individual well-being, gender, and age) and level 2 (class well-being) predictors. Results across the two studies provided converging lines of evidence: students who were in classes with higher levels of life satisfaction and positive affect were also more likely to have higher life satisfaction and positive affect at Time 2. The study indicated that the well-being of a student partly depends on the well-being of their classmates providing evidence for the social contagion of well-being in the classroom context.

    Full Text Available Persons above age 80 comprise the fastest growing segment of the U.S. population, and it is estimated that one in four will need long-term care due to increased disabilities and illness. A major concern for residents, families, and providers is to ensure care that “allows the resident to maintain or attain their highest practicable physical, mental and psychosocial well-being.” The challenge is measuring a subjective concept such as well-being. The Eden Alternative is a current initiative aimed at improving the quality of life and well-being of long-term care residents. The initiative consists of providing long-term care environments that emphasize person-directed decision making and well-being. The purpose of this study was to explore the psychometric properties of the Eden Alternative Well-Being Assessment Tool (EAWBAT. There are three assessment tools designed to measure the well-being of elders (residents, family members of residents, and employees working in the long-term care environments. The sample consisted of 237 residents, 430 employees, and 134 family members from seven Eden Alternative organizations throughout the United States. Factor analysis was completed to identify the underlying structure in these data for elders, employees, and families. Reliability statistics were computed for each scale. Reliability statistics ranged from .876 (employee assessment tool to .949 (family assessment tool, indicating the potential of the EAWBAT to measure the well-being of residents residing in long-term care environments, employees supporting them, and their family members.

    Persistently high rates of cesarean deliveries are cause for concern for physicians, patients, and health systems. Prelabor assessment might be refined by identifying factors that help predict an individual patient's risk of cesarean delivery. Such factors may contribute to patient safety and satisfaction as well as health system planning and resource allocation. In an earlier study, neonatal head circumference was shown to be more strongly associated with delivery mode and other outcome measures than neonatal birthweight. In the present study we aimed to evaluate the association of sonographically measured fetal head circumference measured within 1 week of delivery with delivery mode. This was a multicenter electronic medical record-based study of birth outcomes of primiparous women with term (37-42 weeks) singleton fetuses presenting for ultrasound with fetal biometry within 1 week of delivery. Fetal head circumference and estimated fetal weight were correlated with maternal background, obstetric, and neonatal outcome parameters. Elective cesarean deliveries were excluded. Multinomial regression analysis provided adjusted odds ratios for instrumental delivery and unplanned cesarean delivery when the fetal head circumference was ≥35 cm or estimated fetal weight ≥3900 g, while controlling for possible confounders. In all, 11,500 cases were collected; 906 elective cesarean deliveries were excluded. A fetal head circumference ≥35 cm increased the risk for unplanned cesarean delivery: 174 fetuses with fetal head circumference ≥35 cm (32%) were delivered by cesarean, vs 1712 (17%) when fetal head circumference cesarean delivery by an adjusted odds ratio of 1.75 (95% confidence interval, 1.4-2.18) controlling for gestational age, fetal gender, and epidural anesthesia. The rate of prolonged second stage of labor was significantly increased when either the fetal head circumference was ≥35 cm or the estimated fetal weight ≥3900 g, from 22.7% in the total

    Despite advancing therapeutic strategies, congenital cystadenomatoid malformation of the fetal lung is still a potentially life-threatening anomaly. Antenatally, the development of hydrops as well as the natural history of the malformation is of particular therapeutic and prognostic importance. Postnatally, respiratory distress due to pulmonary hypoplasia counts as a crucial limiting factor. Owing to its feasibility and practicability, as well as a high sensitivity, antenatal ultrasound is still the screening method of choice for the detection of fetal thoracic malformations. However, particularly in cases of indistinguishable sonographic findings, fetal MRI is the modality of choice for proving the diagnosis and preliminary appraisal of intensive care therapy and extracorporal membrane oxygenation postnatally. Furthermore, fetal MRI often facilitates assessment and planning of intrauterine surgical procedures. These two features frequently require a close transfer to an expert neonatal centre. (orig.) [de

    The aim of the study was to assess the sonographic feasibility of measuring the fetal pancreas and its normal development throughout pregnancy. We conducted a cross-sectional prospective study between 19 and 36 weeks' gestation. The study included singleton pregnancies with normal pregnancy follow-up. The pancreas circumference was measured. The first 90 cases were tested to assess feasibility. Two hundred ninety-seven fetuses of nondiabetic mothers were recruited during a 3-year period. The overall satisfactory visualization rate was 61.6%. The intraobserver and interobserver variability had high interclass correlation coefficients of of 0.964 and 0.967, respectively. A cubic polynomial regression described best the correlation of pancreas circumference with gestational age (r = 0.744; P pancreas circumference percentiles for each week of gestation were calculated. During the study period, we detected 2 cases with overgrowth syndrome and 1 case with an annular pancreas. In this study, we assessed the feasibility of sonography for measuring the fetal pancreas and established a normal reference range for the fetal pancreas circumference throughout pregnancy. This database can be helpful when investigating fetomaternal disorders that can involve its normal development. © 2017 by the American Institute of Ultrasound in Medicine.

    Culture has a number of potential impacts upon health and well-being. This project was undertaken to assess the potential impacts of the Liverpool 2008 European Capital of Culture programme upon mental well-being, so that positive effects can be maximized and negative impacts reduced, in order that health and well-being are promoted and inequalities are reduced. A mental well-being impact assessment (MWIA) toolkit has been developed, and was piloted in this study. MWIA uses a sequence of procedures designed to systematically assess the effect of projects, programmes and policies upon people's mental well-being and health. The MWIA toolkit was used to explore the potential positive and negative impacts on mental well-being of a sample of projects and policies from the European Capital of Culture programme. This was achieved by asking stakeholders to answer a series of questions, holding participative workshops, constructing a community profile and reviewing the research literature. Recommendations were developed which aim to enhance the impact of the programme on people's mental well-being. As expected, both positive and negative impacts of the European Capital of Culture programme on mental well-being were identified. Fourteen themes were identified as emerging from the workshops, screening and reviewing the research evidence. Based on these data, 33 recommendations were developed by the project steering group and have been presented to the Liverpool Culture Company. The process of conducting the assessment, particularly its participatory nature and its awareness-raising role, had impacts upon mental well-being. The findings demonstrate the potential for the Culture Company programme to have a profound impact upon mental well-being, and highlight areas which could be addressed to optimize the impact of the programme. 2010 The Royal Society for Public Health.

    The assessment of the urinary system is typically performed by ultrasound. Nevertheless, an ultrasound may be inconclusive in fetuses with renal diseases that result in anhydramnios or oligohydramnios. In such cases, and in other cases in which ultrasound is limited, further investigation with MR should be considered. In the following article, we will provide an overview of the most commonly encountered disorders of the urinary system and their appearance on fetal MR imaging. Fetal MR imaging can accurately diagnose a wide variety of urinary tract disorders and must be seen as a valuable complementary tool to ultrasound in the assessment of the urinary system, particularly in cases of inconclusive ultrasound findings

    To evaluate employee well-being change and associated change in productivity, health risk including biometrics, and workplace support over 2 years after implementation of a well-being improvement strategy. This was an employer case study evaluation of well-being, productivity (presenteeism, absenteeism, and job performance), health risk, and employer support across three employee assessment spanning 2 years. Employee well-being was compared with an independent sample of workers in the community. Well-being and job performance increased and presenteeism and health risk decreased significantly over the 2 years. Employee well-being started lower and increased to exceed community worker averages, approaching significance. Well-being improvement was associated with higher productivity across all measures. Increases in employer support for well-being were associated with improved well-being and productivity. This employer's well-being strategy, including a culture supporting well-being, was associated with improved health and productivity.

    Doppler echocardiography makes it possible to diagnose congenital heart disease in early pregnancy. It allows us to study the anatomical configuration of the fetal heart, and additionally, to evaluate the physiological conditions of the fetus. Evaluation of the direction, velocity, wave form pattern, and quantification of blood flow at the various sites in the fetal heart helps us to assess the characteristics of the fetal circulation and condition of the fetal heart. In order to use this technique in pathological situations, an initial study of the developing normal human fetal circulation was necessary. The authors studied 34 uncomplicated pregnancies by serial Doppler echocardiography. The studies were performed every 4 weeks from 16-weeks gestation to term. The pulsed Doppler sector scanner provided cardiac cross-sectional images, mitral and tricuspid blood velocities were obtained from apical four-chamber views. Angle corrected maximal and mean temporal velocities were calculated by digitizing the Doppler frequency shift recording on a graphic tablet computed with a minicomputer. The angle between the Doppler interrogation beam and the direction of blood flow was kept as small as possible in order to minimize the error

    With all of our present knowledge, high technology diagnostic equipment, electronic databases and other available supporting resources, detection of fetal syndromes is still a challenge for healthcare providers in prenatal as well as in the postnatal period. Prenatal diagnosis of fetal syndromes is not straightforward, and it is a difficult puzzle that needs to be assembled and solved. Detection of one anomaly should always raise a suspicion of the existence of more anomalies, and can be a trigger to investigate further and raise awareness of possible syndromes. Highly specialized software systems for three- and four-dimensional ultrasound (3D/4D US) enabled detailed depiction of fetal anatomy and assessment of the dynamics of fetal structural and functional development in real time. With recent advances in 3D/4D US technology, antenatal diagnosis of fetal anomalies and syndromes shifted from the 2nd to the 1st trimester of pregnancy. It is questionable what can and should be done after the prenatal diagnosis of fetal syndrome. The 3D and 4D US techniques improved detection accuracy of fetal abnormalities and syndromes from early pregnancy onwards. It is not easy to make prenatal diagnosis of fetal syndromes, so tools which help like online integrated databases are needed to increase diagnostic precision. The aim of this paper is to present the possibilities of different US techniques in the detection of some fetal syndromes prenatally.

    In 2006 WHO presented the infant and child growth charts suggested for universal application. However, major determinants for perinatal outcomes and postnatal growth are laid down during antenatal development. Accordingly, monitoring fetal growth in utero by ultrasonography is important both for clinical and scientific reasons. The currently used fetal growth references are derived mainly from North American and European population and may be inappropriate for international use, given possible variances in the growth rates of fetuses from different ethnic population groups. WHO has, therefore, made it a high priority to establish charts of optimal fetal growth that can be recommended worldwide. This is a multi-national study for the development of fetal growth standards for international application by assessing fetal growth in populations of different ethnic and geographic backgrounds. The study will select pregnant women of high-middle socioeconomic status with no obvious environmental constraints on growth (adequate nutritional status, non-smoking), and normal pregnancy history with no complications likely to affect fetal growth. The study will be conducted in centres from ten developing and industrialized countries: Argentina, Brazil, Democratic Republic of Congo, Denmark, Egypt, France, Germany, India, Norway, and Thailand. At each centre, 140 pregnant women will be recruited between 8 + 0 and 12 + 6 weeks of gestation. Subsequently, visits for fetal biometry will be scheduled at 14, 18, 24, 28, 32, 36, and 40 weeks (+/- 1 week) to be performed by trained ultrasonographers.The main outcome of the proposed study will be the development of fetal growth standards (either global or population specific) for international applications. The data from this study will be incorporated into obstetric practice and national health policies at country level in coordination with the activities presently conducted by WHO to implement the use of the Child Growth Standards.

    Fetal movement (FM) counting is a simple and widely used method of assessing fetal well-being. However, little is known about what women perceive as decreased fetal movement (DFM) and how maternally perceived DFM is reflected in FM charts. We analyzed FM counting data from 148 DFM events occurring in 137 pregnancies. The women counted FM daily from pregnancy week 24 until birth using a modified count-to-ten procedure. Common temporal patterns for the two weeks preceding hospital examination due to DFM were extracted from the FM charts using wavelet principal component analysis; a statistical methodology particularly developed for modeling temporal data with sudden changes, i.e. spikes that are frequently found in FM data. The association of the extracted temporal patterns with fetal complications was assessed by including the individuals' scores on the wavelet principal components as explanatory variables in multivariable logistic regression analyses for two outcome measures: (i) complications identified during DFM-related consultations (n = 148) and (ii) fetal compromise at the time of consultation (including relevant information about birth outcome and placental pathology). The latter outcome variable was restricted to the DFM events occurring within 21 days before birth (n = 76). Analyzing the 148 and 76 DFM events, the first three main temporal FM counting patterns explained 87.2% and 87.4%, respectively, of all temporal variation in the FM charts. These three temporal patterns represented overall counting times, sudden spikes around the time of DFM events, and an inverted U-shaped pattern, explaining 75.3%, 8.6%, and 3.3% and 72.5%, 9.6%, and 5.3% of variation in the total cohort and subsample, respectively. Neither of the temporal patterns was significantly associated with the two outcome measures. Acknowledging that sudden, large changes in fetal activity may be underreported in FM charts, our study showed that the temporal FM counting patterns in the two

    Fetal cholelithiasis was first diagnosed in 1983 and since then there have been only few reports about the presence of gallstones in the fetus. Maternal conditions, fetal or obstetrical predisposing risk factors have been proposed to have a causative role, by the pathogenesis of fetal gallstones remains unknown. Clinical sequelae of fetal gallstones are poorly understood as well as the role of fetal cholelithiasis in predisposing the adult to gallstones. They report on 3 patients whose cholelithiasis was diagnosed by obstetrical ultrasonography. Repeated ultrasound scans were performed in each patient until resolution of the US images. The goal of US was to correctly identify the number, size and US features of the material within the gallbladder. The presence of distal shadowing or comet-tail artifact was assess. Multiple, small echogenic foci without distal shadowing were recognized in the fetal gallbladder in their patients. In the third case echogenic foci disappeared during pregnancy. In all the cases, US showed no biliary tract abnormality, and neither the mothers nor the patients had clinical or laboratory findings consistent with liver or biliary diseases. The authors discuss a diagnostic protocol to detect and follow-up gallstones in the perinatal period by ultrasonography. In their experience, fetal cholelithiasis confirmed to be a self-limiting disease without complications and did not require any form of therapy. However a close follow-up is indicated in these patients until spontaneous resolution is demonstrated by US

    Adopting a primary prevention perspective, this study examines competencies with the potential to enhance well-being and performance among future workers. More specifically, the contributions of ability-based and trait models of emotional intelligence (EI), assessed through well-established measures, to indices of hedonic and eudaimonic well-being were examined for a sample of 157 Italian high school students. The Mayer-Salovey-Caruso Emotional Intelligence Test was used to assess ability-based EI, the Bar-On Emotional Intelligence Inventory and the Trait Emotional Intelligence Questionnaire were used to assess trait EI, the Positive and Negative Affect Scale and the Satisfaction With Life Scale were used to assess hedonic well-being, and the Meaningful Life Measure was used to assess eudaimonic well-being. The results highlight the contributions of trait EI in explaining both hedonic and eudaimonic well-being, after controlling for the effects of fluid intelligence and personality traits. Implications for further research and intervention regarding future workers are discussed.

    Fetal magnetic resonance imaging (MRI) examinations have become well-established procedures at many institutions and can serve as useful adjuncts to ultrasound (US) exams when diagnostic doubts remain after US. Due to fetal motion, however, fetal MRI exams are challenging and require the MR scanner to be used in a somewhat different mode than that employed for more routine clinical studies. Herein we review the techniques most commonly used, and those that are available, for fetal MRI with an emphasis on the physics of the techniques and how to deploy them to improve success rates for fetal MRI exams. By far the most common technique employed is single-shot T2-weighted imaging due to its excellent tissue contrast and relative immunity to fetal motion. Despite the significant challenges involved, however, many of the other techniques commonly employed in conventional neuro- and body MRI such as T1 and T2*-weighted imaging, diffusion and perfusion weighted imaging, as well as spectroscopic methods remain of interest for fetal MR applications. An effort to understand the strengths and limitations of these basic methods within the context of fetal MRI is made in order to optimize their use and facilitate implementation of technical improvements for the further development of fetal MR imaging, both in acquisition and post-processing strategies.

    Inequality in use of fetal autopsy is poorly understood, despite the importance of autopsy in establishing the cause of stillbirth for future prevention. We examined fetal autopsy rates between linguistic minorities in Quebec, Canada, and assessed trends over three decades. Using registry data on 11,992 stillbirths from 1981-2011, we calculated fetal autopsy rates for Francophones, Anglophones, and Allophones by decade. We found lower fetal autopsy rates for Allophones (54.4%) than Francophones (68.5%) and Anglophones (63.4%), but rates decreased over time for all language groups. After 2000, Allophones had 25% higher risk of non-autopsy relative to Francophones, with 8.8 fewer autopsies for every 100 stillbirths. Allophones who were not autopsied had 32% higher risk of having an undetermined cause of death. Inequality in use of fetal autopsy may be widespread for minorities in Canada. Efforts to decrease stillbirth in minorities may require policies to increase autopsy rates.

    Full Text Available Creatinine plays a key role in the function and maturation of fetal kidneys throughout pregnancy. It is important to identify other markers that may help in the diagnosis of renal dysfunction. Our aim was to determine the profile of and the correlation between biochemical markers to be used to assess renal function and maturation of the fetus in the amniotic fluid during pregnancy and to determine the distribution of normal values for creatinine, N-acetyl-ß-D-glucosaminidase (NAG, ß2-microglobulin, glucose, urea, sodium, potassium, phosphorus, calcium, uric acid, albumin, and osmolality in three gestational age groups. This was a cross-section study that assessed 115 samples of amniotic fluid during three different periods of pregnancy, i.e., 13 to 20, 27 to 34, and 36 to 42 weeks. Concentrations of creatinine, NAG, urea, potassium and uric acid increased during pregnancy (P0.6, P0.5, P<0.05. NAG, sodium, albumin and osmolality did not show significant correlations (r<0.5, P<0.05. These tests confirmed the important role of creatinine in terms of correlation with gestational age. ß2-Microglobulin, glucose and uric acid were significant as markers of function and maturation of fetal kidneys, whereas NAG did not demonstrate a useful role for the assessment of renal maturation.

    To evaluate the utility of fetal cardiac magnetic resonance imaging (MRI) to diagnose right aortic arch (RAA) with right ductus arteriosus. This retrospective study included six fetuses with right aortic arch and right ductus arteriosus. The six fetal cases were examined using a 1.5-T magnetic resonance unit. The steady-state free precession (SSFP) and single-shot turbo spin echo (SSTSE) sequences were used to evaluate the fetal heart and airway. The gestational age of the six fetuses ranged from 22 to 35 weeks (mean, 26.5 weeks). The age of the pregnant women ranged from 23 to 40 years (mean 31 years). Fetal cardiac MRI diagnosed the six fetal cases with RAA with right ductus arteriosus correctly. Among the six fetuses, four were associated with other congenital heart defects. In three of six cases, the diagnoses established using prenatal echocardiography (echo) was correct when compared with postnatal diagnosis. Fetal cardiac MRI is a useful complementary tool to assess fetuses with RAA and right ductus arteriosus.

    Among the earliest volumes of this Monograph series was a report by Lester Sontag and colleagues, of the esteemed Fels Institute, on the heart rate of the human fetus as an expression of the developing nervous system. Here, some 75 years later, we commemorate this work and provide historical and contemporary context on knowledge regarding fetal development, as well as results from our own research. These are based on synchronized monitoring of maternal and fetal parameters assessed between 24 and 36 weeks gestation on 740 maternal-fetal pairs compiled from eight separate longitudinal studies, which commenced in the early 1990s. Data include maternal heart rate, respiratory sinus arrhythmia, and electrodermal activity and fetal heart rate, motor activity, and their integration. Hierarchical linear modeling of developmental trajectories reveals that the fetus develops in predictable ways consistent with advancing parasympathetic regulation. Findings also include: within-fetus stability (i.e., preservation of rank ordering over time) for heart rate, motor, and coupling measures; a transitional period of decelerating development near 30 weeks gestation; sex differences in fetal heart rate measures but not in most fetal motor activity measures; modest correspondence in fetal neurodevelopment among siblings as compared to unrelated fetuses; and deviations from normative fetal development in fetuses affected by intrauterine growth restriction and other conditions. Maternal parameters also change during this period of gestation and there is evidence that fetal sex and individual variation in fetal neurobehavior influence maternal physiological processes and the local intrauterine context. Results are discussed within the framework of neuromaturation, the emergence of individual differences, and the bidirectional nature of the maternal-fetal relationship. We pose a number of open questions for future research. Although the human fetus remains just out of reach, new

The Mod-MPI is a ratio of isovolumetric to ejection time cardiac time intervals, and the potential for the left ventricular Mod-MPI as a tool to clinically assess fetal cardiac function is well-established. However, there are wide variations in published reference ranges, as (1 a standardised method of selecting cardiac time intervals used in Mod-MPI calculation has not been established; (2 cardiac time interval measurement currently requires manual, inherently subjective placement of callipers on Doppler ultrasound waveforms; and (3 ultrasound machine settings and ultrasound system type have been found to affect Mod-MPI measurement. Collectively these factors create potential for significant inter- and intraobserver measurement variability. Automated measurement of the Mod-MPI may be the next key development which propels the Mod-MPI into routine clinical use. A novel automated system of Mod-MPI measurement is briefly presented and its implications for the future of the Mod-MPI in fetal cardiology are discussed.

    Full Text Available Adopting a primary prevention perspective, this study examines competencies with the potential to enhance well-being and performance among future workers. More specifically, the contributions of ability-based and trait models of emotional intelligence (EI, assessed through well-established measures, to indices of hedonic and eudaimonic well-being were examined for a sample of 157 Italian high school students. The Mayer Salovey Caruso Emotional Intelligence Test (MSCEIT was used to assess ability-based EI, the Bar-On Emotional Intelligence Inventory (EQ-i and the Trait Emotional Intelligence Questionnaire (TeiQue were used to assess trait EI, the Positive and Negative Affect Scale (PANAS and the Satisfaction With Life Scale (SWLS were used to assess hedonic well-being, and the Meaningful Life Measure (MLM was used to assess eudaimonic well-being. The results highlight the contributions of trait emotional intelligence in explaining both hedonic and eudaimonic well-being, after controlling for the effects of fluid intelligence and personality traits. Implications for further research and intervention regarding future workers are discussed.

  18. Assessment of fetal radiation dose to patients and staff in diagnostic radiology

    A major source of uncertainty in the estimation of fetal absorbed radiation dose is the influence of fetal size and position as these change with gestational age. Consequently, dose to the fetus is related to gestational age. Most studies of fetal dose estimation during pregnancy assume that the uterus dose is equal to fetal dose. These dose estimates do not take account of gestational age and individual fetal depth, factors which are significant when calculating dose. To establish both positional and size data for estimation of fetal absorbed dose from radiological examinations, the depths from the mother's anterior surface to the mid-line of the fetal head and abdomen were measured from ultrasound scans in 215 pregnant women. Depths were measured along a ray path projected in the anterior-posterior direction from the mother's abdomen. The fetal size was estimated from measurements of the fetal abdominal and head circumference, femur length and the biparietal diameter. The effects of fetal presentation, maternal bladder volume, placenta location, gestational age and maternal AP thickness on fetal depth and size were analysed. A Monte Carlo (MC) model was developed, and used to derive factors for converting dose-area product and free-in-air entrance surface dose from medical exposure of a pregnant patient to absorbed dose to the uterus/embryo, and for converting uterus dose to fetal dose in the later stages of pregnancy. Also presented are factors for converting thermoluminescence dosimeter reading from occupational exposure of a pregnant worker to equivalent dose to the fetus. The MC model was verified experimentally by direct measurement of uterus depth dose in a female Rando phantom, and also by comparison with other experimental work and MC results in the literature. The application of the various conversion factors is demonstrated by a review of the dose estimation process in 50 cases of fetal irradiation from medical exposures. (author)

    Two peptides [NAPVSIPQ (NAP) and SALLRSIPA (ADNF-9)], that are associated with novel glial proteins regulated by vasoactive intestinal peptide, are shown now to provide protective intervention in a model of fetal alcohol syndrome. Fetal demise and growth restrictions were produced after intraperitoneal injection of ethanol to pregnant mice during midgestation (E8). Death and growth abnormalities elicited by alcohol treatment during development are believed to be associated, in part, with severe oxidative damage. NAP and ADNF-9 have been shown to exhibit antioxidative and antiapoptotic actions in vitro. Pretreatment with an equimolar combination of the peptides prevented the alcohol-induced fetal death and growth abnormalities. Pretreatment with NAP alone resulted in a significant decrease in alcohol-associated fetal death; whereas ADNF-9 alone had no detectable effect on fetal survival after alcohol exposure, indicating a pharmacological distinction between the peptides. Biochemical assessment of the fetuses indicated that the combination peptide treatment prevented the alcohol-induced decreases in reduced glutathione. Peptide efficacy was evident with either 30-min pretreatment or with 1-h post-alcohol administration. Bioavailability studies with [(3)H]NAPVSIPQ indicated that 39% of the total radioactivity comigrated with intact peptide in the fetus 60 min after administration. These studies demonstrate that fetal death and growth restriction associated with prenatal alcohol exposure were prevented by combinatorial peptide treatment and suggest that this therapeutic strategy be explored in other models/diseases associated with oxidative stress.

  20. Aortic isthmus Doppler velocimetry: role in assessment of preterm fetal growth restriction.

    Intrauterine fetal growth restriction (IUGR) is an important pregnancy complication associated with significant adverse clinical outcome, stillbirth, perinatal morbidity and cerebral palsy. To date, no uniformly accepted management protocol of Doppler surveillance that reduces mortality and cognitive morbidity has emerged. Aortic isthmus (AoI) evaluation has been proposed as a potential monitoring tool for IUGR fetuses. In this review, the current knowledge of the relationship between AoI Doppler velocimetry and preterm fetal growth restriction is reviewed. Relevant technical aspects and reproducibility data are reviewed as we discuss AoI Doppler and its place within the existing repertoire of Doppler assessments in placental insufficiency. The AoI is a link between the right and left ventricles which perfuse the lower and upper body, respectively. The clinical use of AoI waveforms for monitoring fetal deterioration in IUGR has been limited, but preliminary work suggests that abnormal AoI impedance indices are an intermediate step between placental insufficiency-hypoxemia and cardiac decompensation. Further prospective studies correlating AoI indices with arterial and venous Doppler indices and perinatal outcome are required before encorporating this index into clinical practice.

    Improving physician health and performance is critical to successfully meet the challenges facing health systems that increasingly emphasize productivity. Assessing long-term efficacy and sustainability of programs aimed at enhancing physician and organizational well-being is imperative. To determine whether data-guided interventions and a systematic improvement process to enhance physician work-life balance and organizational efficacy can improve physician and organizational well-being. From 2000 to 2005, 22-32 physicians regularly completed 3 questionnaires coded for privacy. Results were anonymously reported to physicians and the organization. Data-guided interventions to enhance physician and organizational well-being were built on physician control over the work environment, order in the clinical setting, and clinical meaning. Questionnaires included an ACP/ASIM survey on physician satisfaction, the Maslach Burnout Inventory (MBI), and the Quality Work Competence (QWC) survey. Emotional and work-related exhaustion decreased significantly over the study period (MBI, p = 0.002; QWC, p = 0.035). QWC measures of organizational health significantly improved initially and remained acceptable and stable during the rest of the study. A data-guided program on physician well-being, using validated instruments and process improvement methods, enhanced physician and organizational well-being. Given the increases in physician burnout, organizations are encouraged to urgently create individual and systems approaches to lessen burnout risk.

  2. THE POSSIBILITIES TO DETERMINE FETAL MATURITY BY ULTRASOUND DIAGNOSTICS

    Full Text Available Background: Extragenital disorders in a pregnant patient, as well as complications of pregnancy often necessitate preterm delivery, when the state of the fetus is one of the criteria determining terms and type of delivery. In connection with this, the physician faces the challenge of accurate assessment of fetal maturity. Aim: To identify ultrasound signs of functional fetal maturity. Materials and methods: 120 pregnant patients were assessed at 35 to 40 weeks of gestation. Beyond a standard fetometry, we assessed interhemispheric cerebellar size, the biggest size of the Beclard’s nucleus, the ratio of cortical to medullar substance of fetal adrenal glands (adrenal coefficient, the ration between ultrasound density of lungs, liver and ultrasound density of fetal urine (histogram analysis. Results: Up to 36 weeks of gestation, the interhemispheric cerebellar size was below 52 mm, starting from 37 weeks, above 53 mm and from week 40 on, above 58 mm. All newborns, which had their interhemispheric cerebellar size ≥ 53 mm antenatally, were assessed as being mature at birth (p < 0.05. All newborns, which had Beclard’s nucleus size ≥ 5 mm antenatally, were assessed as being mature at birth (p < 0.05. At 35–35.6 weeks of gestation, mean adrenal coefficients in all cases exceeded 1. Starting with full 36 weeks of gestation onwards, this parameter decreased to 0.94 and showed a steady decrease thereafter. There were no signs of functional immaturity or respiratory distress among newborns with antenatal adrenal coefficient of ≤ 0.99 (p < 0.05. The ratio between ultrasound density of lungs to ultrasound density of bladder contents increases up to 37 weeks of gestation and remains stable up to 40 weeks. The ratio of liver density to the same substrate is non-significantly lower due to lower ultrasound density of the liver itself. The ratio of ultrasound density of the lung to that of the liver up to 36 weeks was at least 1.41 and decreased

    Full Text Available The aim of this study is to investigate that fetal heart rates (fHR extracted from fetal phonocardiography (fPCG could convey similar information of fHR from cardiotocography (CTG. Four-channel fPCG sensors made of low cost (<$1 ceramic piezo vibration sensor within 3D-printed casings were used to collect abdominal phonogram signals from 20 pregnant mothers (>34 weeks of gestation. A novel multi-lag covariance matrix-based eigenvalue decomposition technique was used to separate maternal breathing, fetal heart sounds (fHS and maternal heart sounds (mHS from abdominal phonogram signals. Prior to the fHR estimation, the fPCG signals were denoised using a multi-resolution wavelet-based filter. The proposed source separation technique was first tested in separating sources from synthetically mixed signals and then on raw abdominal phonogram signals. fHR signals extracted from fPCG signals were validated using simultaneous recorded CTG-based fHR recordings.The experimental results have shown that the fHR derived from the acquired fPCG can be used to detect periods of acceleration and deceleration, which are critical indication of the fetus' well-being. Moreover, a comparative analysis demonstrated that fHRs from CTG and fPCG signals were in good agreement (Bland Altman plot has mean = −0.21 BPM and ±2 SD = ±3 with statistical significance (p < 0.001 and Spearman correlation coefficient ρ = 0.95. The study findings show that fHR estimated from fPCG could be a reliable substitute for fHR from the CTG, opening up the possibility of a low cost monitoring tool for fetal well-being.

    The external cephalic version (ECV) of the fetus at term reduces the maternal and fetal risks of intrapartum breech presentation and Caesarean delivery. Since 1986 over 800 external cephalic versions were performed in the outpatient Department of Obstetrics and Gynaecology of the Städtische Frauenklinik Stuttgart. 60.5% were successful. NO severe complications occurred. Sufficient amniotic fluid as well as the mobility of the fetal breech is a major criterion for the success of the ECV. Management requires a safe technique for mother and fetus. This includes ultrasonography, elektronic fetal monitoring and the ability to perform immediate caesarean delivery as well as the performance of ECV without analgesicas and sedatives. More than 70% of the ECV were successful without tocolysis. In unsuccessful cases the additional use of tocolysis improves the success rate only slightly. Therefore routine use of tocolysis does not appear necessary. External cephalic version can be recommended as an outpatient treatment without tocolysis.

    The objective of this publication is to present a guideline for the dose assessment through a comprehensive introduction of knowledge on ionizing radiation, radiation protection during pregnancy and fetal dosimetry for physician and other professionals involved in nuclear medicine practices. It contains tables with recommended dose estimates at all stages of pregnancy for many radiopharmaceuticals. Compounds for which some information was available regarding placental crossover are shown in shaded rows. It includes the most common diagnostic and therapy practices in nuclear medicine considering the four radioactive isotopes selected: 99m Tc, 131 I, 201 Tl and 67 Ga. There is a special case included, it is when conception occurs after the iodine has been administered. In almost every case, the diagnostic benefit to the mother outweighs the risk of any irradiation of the fetus. However, there is one situation in which severe fetal injury can be incurred from administering a radiopharmaceutical to the mother, and that is use of iodine-131 therapy for ablation of the thyroid in cases of hyperthyroidism or carcinoma. Radioactive iodine readily crosses the placenta and concentrates in the fetal thyroid, where, because of its small organ mass, high radiation doses are received. (author)

    To assess incidence and risk factors of intimate partner violence (IPV) during pregnancy among a sample of women from Egypt and to evaluate its impact on maternal and fetal adverse health outcomes. After obtaining ethical approval, a total of 1,857 women aged 18 - 43 years completed the study and were investigated using an interview questionnaire. The questionnaire contains five main items: demographic characteristics of women, intimate partner characteristics, assessment of IPV during current pregnancy, and assessment of maternal as well as fetal/neonatal adverse outcomes. Women were also examined to detect signs of violence and identify injuries. Exposure to IPV during pregnancy was reported among 44.1% of the studied women. Emotional violence was the most common form. Women exposed to violence were of younger age, higher parity, and lower educational level. Their partners were older, less educated, and more likely to be addicted to drugs and alcohol. Women were also found to have significantly higher incidence of adverse pregnancy outcomes (miscarriage, preterm labor, and premature rupture of membrane), and fetal/neonatal adverse outcomes (fetal distress, fetal death, and low birth weight). A total of 297 cases had been exposed to physical violence (15.9%) vs 32.6% and 10% exposed to emotional and sexual violence, respectively. The most common form of physical violence was kicking. Violence during pregnancy is prevalent among Egyptian women. Exposure to violence was a significant risk factor for multiple adverse maternal and fetal health outcomes.

    Full Text Available Purpose: To investigate the possible effects of the fetal echocardiography experience on the prenatal attachment process. The predictive effect of specific women’s psychological variables will be explored as well.Design and methods: This between groups study involved 85 women with pregnancy at risk who underwent the fetal echocardiography, and 83 women who were about to undergo the morphological scan. The tools employed were: the Prenatal Attachment Inventory (P.A.I. to explore the maternal-fetal attachment; the Maternity Social Support Scale to investigate the woman perception of being socially supported during pregnancy; both the Big Five Questionnaire and the FACES III to explore the personality traits of pregnant women and their perception of their couple relationship functioning.Findings: The outcomes of ANOVA do not show statistically significant differences between the two groups of the mothers-to-be with regard to the scores of the P.A.I. (F = .017; p = .897; η2 = .000, while the regression analysis of the possible effect of the maternal psychological variables on the mother-fetus relationship shows a statistically significant result only with regard to the “social support” variable (r2 = .061; df = 80; p = .025.Conclusions: It would seem that the process of the prenatal attachment develops independently whether the woman has to undergo a first level screening or a second level examination such as the fetal echocardiography.

    Magnetic resonance imaging (MRI) was performed in 36 patients at between 10 and 38 weeks gestation to determine the fetal anatomy that could be identified at different gestations. Fetal motion significantly degraded the image quality in the first and second trimesters, but in the final trimester fetal anatomy was clearly demonstrated. T2 weighted sequences showed the fetal brain and lungs to have a high signal intensity. Shorter TR leading to a T1 weighting gave better resolution of the overall anatomy. MRI has revealed the potential for assessment of lung maturity and the growth-retarded fetus.

    The developing fetal brain is vulnerable to a variety of environmental agents including maternal ethanol consumption. Preclinical studies on the development and amelioration of fetal teratology would be significantly facilitated by the application of high resolution imaging technologies like optical coherence tomography (OCT) and high-frequency ultrasound (US). This study investigates the ability of these imaging technologies to measure the effects of maternal ethanol exposure on brain development, ex vivo, in fetal mice. Pregnant mice at gestational day 12.5 were administered ethanol (3 g/Kg b.wt.) or water by intragastric gavage, twice daily for three consecutive days. On gestational day 14.5, fetuses were collected and imaged. Three-dimensional images of the mice fetus brains were obtained by OCT and high-resolution US, and the volumes of the left and right ventricles of the brain were measured. Ethanol-exposed fetuses exhibited a statistically significant, 2-fold increase in average left and right ventricular volumes compared with the ventricular volume of control fetuses, with OCT-derived measures of 0.38 and 0.18 mm3, respectively, whereas the boundaries of the fetal mouse lateral ventricles were not clearly definable with US imaging. Our results indicate that OCT is a useful technology for assessing ventriculomegaly accompanying alcohol-induced developmental delay. This study clearly demonstrated advantages of using OCT for quantitative assessment of embryonic development compared with US imaging.

    Full Text Available Fetal Middle Cerebral Artery Peak Systolic Velocity (MCA-PSV is being increasingly used for non-invasively diagnosing fetal anemias irrespective of their cause. A study was therefore undertaken to find out what different scenarios can be encountered in the local obstetric population. Doppler ultrasound measurements of fetal MCA-PSV were done in 1200 pregnant women who were referred for antenatal ultrasound between 12 - 40 weeks of gestation. Statistical analysis was done using Microsoft Excel 2007 and SPSS software version 12. The different scenarios encountered in this study were then compiled and are presented here. With increasing gestational age, the value of MCA-PSV was seen to increase correspondingly in all normal fetuses. This correlation between the two was thus positive and was found to be statistically significant (p < 0.05. Abnormally raised values of MCA-PSV were seen in fetuses with severe anemia due to ABO-Rh Iso-immunization which left untreated, ultimately resulted in fetal hydrops. Almost similar and normal values were seen in separate as well as conjoint healthy twins. Abnormally elevated values were seen in twins with discordant growths. Fetal MCA-PSV is very useful to confirm the presence or absence of fetal anemia irrespective of underlying cause in singleton as well as twin pregnancies. For complete assessment, it is essential that the specialist is thoroughly aware of the different scenarios that can be encountered while using this non-invasive method.

    To evaluate the effect of fetal sex on singleton pregnancy growth charts customized for parental characteristics, race, and parity Methods: In a multicentric cross-sectional study, 8070 ultrasonographic examinations from low-risk singleton pregnancies between 16 and 40 weeks of gestation were considered. The fetal measurements obtained were biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL). Quantile regression was used to examine the impact of fetal sex across the biometric percentiles of the fetal measurements considered together with parents' height, weight, parity, and race. Fetal gender resulted to be a significant covariate for BDP, HC, and AC with higher values for male fetuses (p ≤ 0.0009). Minimal differences were found among sexes for FL. Parity, maternal race, paternal height and maternal height, and weight resulted significantly related to the fetal biometric parameters considered independently from fetal gender. In this study, we constructed customized biometric growth charts for fetal sex, parental, and obstetrical characteristics using quantile regression. The use of gender-specific charts offers the advantage to define individualized normal ranges of fetal biometric parameters at each specific centile. This approach may improve the antenatal identification of abnormal fetal growth.

    Rh-isoimmunization is a pathological condition in which the fetal red blood cells of a Rh (+) fetus are destroyed by the isoantibodies of a Rh (-) woman sensitized in a previous event. Despite of the wide spread implementation of anti D-gammaglobolin prophylaxis this is still the most common cause for fetal anemia. Recently, sonographic measurement of the fetal middle cerebral artery peak systolic velocity (MCA-PSV) has been shown to be an accurate non-invasive test to predict low fetal hemoglobin levels. We present a case report of Rh-alloimmunized pregnancy with moderate fetal anemia, followed-up by weekly MCA-PSV measurements. A 37-year-old Rh (-) negative gravida 3, para 1, without anti-D gammaglobolin prophylaxis in her previous pregnancies, presented at 27+0 weeks of gestation (w.g.) for a routine third trimester scan. Subsequent ultrasound measurements of MCA-PSV confirmed a progressive increase of the peak systolic velocities from 40 to 80 cm/sec, as well as a gradual rise in the anti-D titers. The evidence of developing fetal anemia necessitated elective Caesarean section performed at 35 wg. The neonate was admitted in the intensive care unit and required resuscitation, one exchange blood transfusion and several courses of phototherapy. The patient was discharged two weeks post partum. There is a strong correlation between the high peak systolic velocities in the middle cerebral artery (MCA-PSV) and the low levels of fetal hemoglobin. The high sensitivity and positive predictive value concerning the development of fetal anemia, as well as its good repeatability, makes this non-invasive test a valuable asset in the management of all pregnancies complicated by severe Rh-alloimmunization.

    Non-invasive monitoring of fetal electrocardiogram (fECG) plays an important role in detecting and diagnosing fetal diseases. This study aimed to develop a multi-step method for locating both maternal and fetal QRS complexes from abdominal ECG (aECG) recordings. The proposed method included four major steps: abdominal ECG pre-processing, maternal QRS complex locating, maternal ECG cancellation and fetal QRS complex locating. Signal quality assessment (SQA) and fine-tuning for maternal ECG (FTM) were implemented in the first and third steps, respectively. The method was then evaluated using 75 non-invasive 4-channel aECG recordings provided by the PhysioNet/Computing in Cardiology Challenge 2013. The F 1 measure, which is a new index introduced by Behar et al (2013 Proc. Comput. Cardiol. 40 297–300), was used to assess the locating accuracy. The other two indices, mean squared error of heart rate (MSE H R) between the fetal HR signals estimated from the reference and our method (MSE H R in bpm 2 ) and root mean squared difference between the corresponding fetal RR intervals (MSE R R in ms) were also used to assess the locating accuracy. Overall, for the maternal QRS complex, the F 1 measure was 98.4% from the method without the implementation of SQA, and it was improved to 99.8% with SQA. For the fetal QRS complex, the F 1 measure, MSE H R and MSE R R were 84.9%, 185.6 bpm 2 and 19.4 ms for the method without both SQA and FTM procedures. They were improved to 93.9%, 47.5 bpm 2 and 7.6 ms with both SQA and FTM procedures. These improvements were observed from each individual subject. It can be concluded that implementing both SQA and FTM procedures could achieve better performance for locating both maternal and fetal QRS complexes. (paper)

Biometric and self-reported outcomes were assessed among 677 retail distribution center employees before and after a 6-month well-being intervention. Despite lower well-being at baseline compared to an independent random sample of workers, program participants' well-being, productivity, body mass index, systolic blood pressure, and total cholesterol improved significantly after the intervention, whereas the decline in diastolic blood pressure was not significant. Moreover, participants' specific transition across well-being segments over the intervention period demonstrated more improvement than decline. There is evidence that programs designed to improve well-being within a workforce can be used to significantly and positively impact employee health and productivity, which should result in reduced health care costs, improved employee productivity, and increased overall profitability.

    Currently available fetal intervention techniques rely on invasive procedures that carry inherent risks. A non-invasive technique for fetal intervention could potentially reduce the risk of fetal and obstetric complications. Pulsed cavitational ultrasound therapy (histotripsy) is an ablation technique that mechanically fractionates tissue at the focal region using extracorporeal ultrasound. In this study, we investigated the feasibility of using histotripsy as a non-invasive approach to fetal intervention in a sheep model. The experiments involved 11 gravid sheep at 102-129 days of gestation. Fetal kidney, liver, lung and heart were exposed to ultrasound pulses (bones. Histological assessment confirmed lesion locations and sizes corresponding to regions where cavitation was monitored, with no lesions found when cavitation was absent. Inability to generate cavitation was primarily associated with increased depth to target and obstructing structures such as fetal limbs. Extracorporeal histotripsy therapy successfully created targeted lesions in fetal sheep organs without significant damage to overlying structures. With further improvements, histotripsy may evolve into a viable technique for non-invasive fetal intervention procedures. Copyright © 2011 ISUOG. Published by John Wiley & Sons, Ltd.

    New, ultrafast sequences have made it possible to obtain MR images of the fetus without maternal sedation or immobilization of the fetus itself. While fetal MRI began as an adjunct to ultrasound, it has now been shown that MRI can provide additional information that may change prognosis, the management of pregnancy, or the treatment of the newborn child. It is of particular value in the assessment of malformations of the central nervous system. The steady development and adaptation of MR-sequences to the needs of fetal imaging has led to new indications that can support prognostic and therapeutic decisions. (orig.)

    Introduction With advancing technology it has become possible to accurately record and assess fetal heart rate (FHR) patterns from gestations as early as 20 weeks. The aim of our study was to describe early patterns of FHR, as recorded by transabdominal fetal electrocardiogram according to the Dawes-Redman criteria. Accordingly, short-term variability, basal heart rate, accelerations and decelerations were quantified at 20-24 weeks gestation among women with uncomplicated pregnancies. Methods This study was conducted in a subset of participants enrolled in a large prospective pregnancy cohort study. Our final data set consisted of 281 recordings of women with good perinatal outcomes that had undergone fetal electrocardiographic assessment as part of the Safe Passage Study. Results The success rate of the recordings was 95.4%. The mean frequency of small and large accelerations was 0.5 and 0.1 per 10 minutes respectively and that of small and large decelerations 0.3 and 0.008 per 10 minutes respectively. The mean and basal heart rates were both equal to 148.0 bpm at a median gestation of 161 days. The mean short term variation was 6.2 (SD 1.4) milliseconds and mean minute range 35.1 (SD 7.1) milliseconds. Conclusion The 20 to 24 week fetus demonstrates FHR patterns with more accelerations and decelerations, as well as higher baseline variability than was anticipated. Information from this study provides an important foundation for further, more detailed, studies of early FHR patterns. PMID:23991757

    Full Text Available We report two cases of pulmonary hypoplasia due to fetal ascites in symptomatic congenital cytomegalovirus (CMV infections despite fetal therapy. The patients died soon after birth. The pathogenesis of pulmonary hypoplasia in our cases might be thoracic compression due to massive fetal ascites as a result of liver insufficiency. Despite aggressive fetal treatment, including multiple immunoglobulin administration, which was supposed to diminish the pathogenic effects of CMV either by neutralization or immunomodulatory effects, the fetal ascites was uncontrollable. To prevent development of pulmonary hypoplasia in symptomatic congenital CMV infections, further fetal intervention to reduce ascites should be considered.

    Despite more than three decades of universal popularity of fetal sonography as an integral part of pregnancy evaluation, there is still no unequivocal agreement regarding the optimal dating of fetal sonographic screening and the type of ultrasound (transvaginal vs abdominal). TransvaginaL systematic sonography at 14-17 weeks for fetal organ screening. The evaluation of over 72.000 early (14-17 weeks) and late (18-24 weeks) fetal ultrasonographic systematic organ screenings revealed that 96% of the malformations are detectable in the early screening with an incidence of 1:50 gestations. Only 4% of the fetal anomalies are diagnosed later in pregnancy. Over 99% of the fetal cardiac anomalies are detectable in the early screening and most of them appear in low risk gestations. Therefore, we suggest a new platform of fetal sonographic evaluation and follow-up: The extensive systematic fetal organ screening should be performed by an expert sonographer who has been trained in the detection of fetal malformations, at 14-17 weeks gestation. This examination should also include fetal cardiac echography Three additional ultrasound examinations are suggested during pregnancy: the first, performed by the patient's obstetrician at 6-7 weeks for the exclusion of ectopic pregnancy, confirmation of fetal viability, dating, assessment of chorionicity in multiple gestations, and visualization of maternal adnexae. The other two, at 22-26 and 32-34 weeks, require less training and should be performed by an obstetrician who has been qualified in the sonographic detection of fetal anomalies. The advantages of early midtrimester targeted fetal systematic organ screening for the detection of fetal anomalies may dictate a global change.

    Assessment of the fetal medulla oblongata volume (MOV) and blood flow might be important in the evaluation of fetal brain growth. We used three-dimensional power Doppler ultrasound (3DPDUS) to assess the fetal MOV and blood flow index in normal gestation. The relationships between these parameters were further analyzed. We assessed the total volume and blood flow index of the fetal MO in normal pregnancies using a 3DPDUS (Voluson 730 Expert). The true sagittal plane over the fetal occipital area was measured by a 3D transabdominal probe to scan the fetal MO under the power Doppler mode. Then, we quantitatively assessed the total volume of the fetal MOV, mean gray area (MG), vascularization index (VI), and flow index (FI). A total of 106 fetuses, ranging from 19 weeks to 39 weeks of gestation, were involved in our study. The volume of the fetal MO was highly positively correlated with gestational age [correlation coefficient (r) = 0.686, p < 0.0001]. The MG was negatively correlated with gestational age [r = -0.544, p < 0.0001). VI and FI showed no significant correlation with gestational age (p = 0.123 and p = 0.219, respectively). 3DPDUS can be used to assess the fetal MOV and blood flow development quantitatively. Our study indicated that fetal MOV and blood flow correlated significantly with the advancement of gestational age. This information may serve as reference data for further studies of the fetal brain and blood flow under abnormal conditions. Copyright © 2016. Published by Elsevier B.V.

    Evaluation of fetal motility can give insight in fetal health, as a strong decrease can be seen as a precursor to fetal death. Typically, the assessment of fetal health by fetal movement detection relies on the maternal perception of fetal activity. The percentage of detected movements is strongly subject dependent and with undivided attention of the mother varies between 37% to 88%. Various methods to assist in fetal movement detection exist based on a wide spectrum of measurement techniques. However, these are typically unsuitable for ambulatory or long-term observation. In this paper, a novel method for fetal motion detection is presented based on amplitude and shape changes in the abdominally recorded fetal ECG. The proposed method has a sensitivity and specificity of 0.67 and 0.90, respectively, outperforming alternative fetal ECG-based methods from the literature.

    Spinal dysraphism or neural tube defects (NTD) encompass a heterogeneous group of congenital spinal anomalies that result from the defective closure of the neural tube early in gestation with anomalous development of the caudal cell mass. Advances in ultrasound and MRI have dramatically improved the diagnosis and therapy of spinal dysraphism and caudal spinal anomalies both prenatally and postnatally. Advances in prenatal US including high frequency linear transducers and three dimensional imaging can provide detailed information concerning spinal anomalies. MR imaging is a complementary tool that can further elucidate spine abnormalities as well as associated central nervous system and non-CNS anomalies. Recent studies have suggested that 3-D CT can help further assess fetal spine anomalies in the third trimester. With the advent of fetal therapy including surgery, accurate prenatal diagnosis of open and closed spinal dysraphism becomes critical in appropriate counselling and perinatal management. (orig.)

    Doppler ultrasound has become a part of routine antenatal fetal surveillance during the past two decades. It provides insight into the utero-placental and fetal arterial, venous circulation non-invasively. Doppler examination has a key role in the detection of hypoxic risk since abnormal blood flow patterns can be demonstrated before the clinical manifestation of fetal disorder. Doppler velocimetry facilitates judgment in the diagnosis, monitoring fetal well-being during pregnancy and labor, scheduling antenatal tests and timing delivery. Authors review the effects of chronic and acute hypoxia on fetal hemodynamics. On the basis of the present knowledge and experience a brief summary is given about the role of Doppler velocimetry in the early detection of hypoxic fetal jeopardy during pregnancy and labor.

    Objectives Eye movements are the physical expression of upper fetal brainstem function. Our aim was to identify and differentiate specific types of fetal eye movement patterns using dynamic MRI sequences. Their occurrence as well as the presence of conjugated eyeball motion and consistently parallel eyeball position was systematically analyzed. Methods Dynamic SSFP sequences were acquired in 72 singleton fetuses (17–40 GW, three age groups [17–23 GW, 24–32 GW, 33–40 GW]). Fetal eye movements were evaluated according to a modified classification originally published by Birnholz (1981): Type 0: no eye movements; Type I: single transient deviations; Type Ia: fast deviation, slower reposition; Type Ib: fast deviation, fast reposition; Type II: single prolonged eye movements; Type III: complex sequences; and Type IV: nystagmoid. Results In 95.8% of fetuses, the evaluation of eye movements was possible using MRI, with a mean acquisition time of 70 seconds. Due to head motion, 4.2% of the fetuses and 20.1% of all dynamic SSFP sequences were excluded. Eye movements were observed in 45 fetuses (65.2%). Significant differences between the age groups were found for Type I (p = 0.03), Type Ia (p = 0.031), and Type IV eye movements (p = 0.033). Consistently parallel bulbs were found in 27.3–45%. Conclusions In human fetuses, different eye movement patterns can be identified and described by MRI in utero. In addition to the originally classified eye movement patterns, a novel subtype has been observed, which apparently characterizes an important step in fetal brainstem development. We evaluated, for the first time, eyeball position in fetuses. Ultimately, the assessment of fetal eye movements by MRI yields the potential to identify early signs of brainstem dysfunction, as encountered in brain malformations such as Chiari II or molar tooth malformations.

    Full Text Available Background. Presumably, the academic stress that builds throughout the academic year has a negative effect on dental students’ psychological well-being and may have a relationship with academic performance. This research aimed to analyse the variation of positive well-being in second-year dental students, across the academic semester, in relation to consecutive examinations as part of academic assessment system (1 and to observe the relationship between academic performance during semester evaluation period and dental students’ positive well-being (2. Methods. A prospective study was conducted on second-year dental students, data on positive well-being being collected with WHO-Five Well-Being Index (WHO-5, at the beginning of the semester and after three consecutive mandatory examinations. Results. One hundred and forty-six dental students were included (77% response rate. Repeated ANOVA showed a significant progressive decline of positive well-being over the semester, which was clinically significant for an important part of them. Students who performed better in the semester evaluation period registered higher well-being levels at the beginning of the semester but a more pronounced decline of it until the semester evaluation period. Conclusion. Based on this research, a relationship between positive well-being, academic assessments, and academic performance is suggested, when evaluating them in a prospective frame.

    Full Text Available Corpus callosum agenesis (CCA was evaluated by ultrasound examination and magnetic resonance imaging (MRI with many studies. Ultrasonography was able to suspect CCA by indirect signs but a definitive diagnosis of CCA was achieved in rare cases. MRI was able to diagnose complete CCA in majority of cases. Additional neurological abnormalities including heterotopia, gyration anomaly, asymmetry of the cerebral hemispheres, and Dandy-Walker variant were documented, as well as an ocular anomaly which was described, by MRI examination. Prenatal counseling for fetal agenesis of the corpus callosum is difficult as the prognosis is uncertain. The association with other cerebral abnormalities increases the likelihood of a poor outcome and ultrasonographic assessment of the fetal brain is limited. We found MRI to be a safe and useful additional procedure to complement ultrasonographic diagnosis or suspicion of CCA.

    Physician utilization of well-being resources remains low despite efforts to promote use of these resources. We implemented a well-being assessment for internal medicine residents to improve access and use of mental health services. We scheduled all postgraduate year 1 (PGY-1) and PGY-2 residents at West Virginia University for the assessment at our faculty and staff assistance program (FSAP). While the assessment was intended to be universal (all residents), we allowed residents to "opt out." The assessment visit consisted of an evaluation by a licensed therapist, who assisted residents with a wellness plan. Anonymous surveys were distributed to all residents, and means were compared by Student's t test. Thirty-eight of 41 PGY-1 and PGY-2 residents (93%) attended the scheduled appointments. Forty-two of 58 residents (72%, including PGY-3s) completed the survey. Of 42 respondents, 28 (67%) attended the assessment sessions, and 14 (33%) did not. Residents who attended the sessions gave mean ratings of 7.8 for convenience (1, not convenient, to 9, very convenient), and 7.9 for feeling embarrassed if colleagues knew they attended (1, very embarrassed, to 9, not embarrassed). Residents who attended the assessment sessions reported they were more likely to use FSAP services in the future, compared with those who did not attend ( P  barriers to using counseling resources. The majority of residents who participated had a positive view of the program and indicated they would return to FSAP if they felt they needed counseling.

    The purpose of this study is to evaluate pulmonary hypoplasia of the fetus using MRI. The subjects consisted of 36 fetuses (18 to 40 weeks' gestation). All fetuses or mothers had major anomalies diagnosed on fetal ultrasonography. MR imaging was performed with a 1.5-T magnet and HASTE (half-Fourier acquisition single-shot turbo spin-echo) sequence. MR images were evaluated with special attention to the intensity of the lung. A diagnosis of pulmonary hypoplasia was based on the clinical, surgical, and autopsy findings. All fetuses with normal pulmonary development showed high intensity in the lung, while all fetuses with pulmonary hypoplasia showed a low intensity in the lung, obscured pulmonary vessels and a small thorax. There was a close correlation between the lung intensity and pulmonary growth. MR assessment of lung intensity may facilitate the diagnosis of pulmonary hypoplasia, particularly after 26 weeks' gestation. Some of the normally developing lung showed a low intensity from 20 to 24 weeks of gestational age. The change to normal lung intensity may occur during this period. (author)

    Intrauterine growth restriction (IUGR) is interconnected with developmental programming of lifelong pathophysiology. IUGR is seen in human multifetal pregnancies, with stepwise rises in fetal numbers interfering with placental nutrient delivery. It remains unknown whether fetal blood analyses would reflect fetal nutrition, liver, and excretory function in the last trimester of human or ovine IUGR In an ovine model, we hypothesized that fetal plasma biochemical values would reflect progressive placental, fetal liver, and fetal kidney dysfunction as the number of fetuses per gestation rose. To determine fetal plasma biochemical values in singleton, twin, triplet, and quadruplet/quintuplet ovine gestation, we investigated morphometric measures and comprehensive metabolic panels with nutritional measures, liver enzymes, and placental and fetal kidney excretory measures at gestational day (GD) 130 (90% gestation). As anticipated, placental dysfunction was supported by a stepwise fall in fetal weight, fetal plasma glucose, and triglyceride levels as fetal number per ewe rose. Fetal glucose and triglycerides were directly related to fetal weight. Plasma creatinine, reflecting fetal renal excretory function, and plasma cholesterol, reflecting placental excretory function, were inversely correlated with fetal weight. Progressive biochemical disturbances and growth restriction accompanied the rise in fetal number. Understanding the compensatory and adaptive responses of growth-restricted fetuses at the biochemical level may help explain how metabolic pathways in growth restriction can be predetermined at birth. This physiological understanding is important for clinical care and generating interventional strategies to prevent altered developmental programming in multifetal gestation. © 2016 The Authors.

    Fetal monitoring during labour currently fails to accurately detect acidemia. We developed a method to assess the multidimensional properties of fetal heart rate variability (fHRV) from trans-abdominal fetal electrocardiogram (fECG) during labour. We aimed to assess this novel bioinformatics approach for correlation between fHRV and neonatal pH or base excess (BE) at birth. We enrolled a prospective pilot cohort of uncomplicated singleton pregnancies at 38–42 weeks’ gestation in Milan, Italy, and Liverpool, UK. Fetal monitoring was performed by standard cardiotocography. Simultaneously, with fECG (high sampling frequency) was recorded. To ensure clinician blinding, fECG information was not displayed. Data from the last 60 min preceding onset of second-stage labour were analyzed using clinically validated continuous individualized multiorgan variability analysis (CIMVA) software in 5 min overlapping windows. CIMVA allows simultaneous calculation of 101 fHRV measures across five fHRV signal analysis domains. We validated our mathematical prediction model internally with 80:20 cross-validation split, comparing results to cord pH and BE at birth. The cohort consisted of 60 women with neonatal pH values at birth ranging from 7.44 to 6.99 and BE from −0.3 to −18.7 mmol L −1 . Our model predicted pH from 30 fHRV measures (R 2 = 0.90, P < 0.001) and BE from 21 fHRV measures (R 2 = 0.77, P < 0.001). Novel bioinformatics approach (CIMVA) applied to fHRV derived from trans-abdominal fECG during labor correlated well with acid-base balance at birth. Further refinement and validation in larger cohorts are needed. These new measurements of fHRV might offer a new opportunity to predict fetal acid-base balance at birth. (fast track communication)

    Well-being impact assessments of urban interventions are a difficult challenge, as there is no agreed methodology and scarce evidence on the relationship between environmental conditions and well-being.

    To estimate fetal absorbed dose from radiographic examinations, the depth from the anterior maternal surface to the midline of the fetal skull and abdomen was measured by ultrasound in 97 pregnant women. The relationships between fetal depth, fetal presentation, and maternal parameters of height, weight, anteroposterior (AP) thickness, gestational age, placental location, and bladder volume were analyzed. Maternal AP thickness (MAP) can be estimated from gestational age, maternal height, and maternal weight. Fetal midskull and abdominal depths were nearly equal. Fetal depth normalized to MAP was independent or nearly independent of maternal parameters and fetal presentation. These data enable a reasonable estimation of absorbed dose to fetal brain, abdomen, and whole body

    Fetal MRI is clinically performed to evaluate the brain in cases where an abnormality is detected by prenatal sonography. These most commonly include ventriculomegaly, abnormalities of the corpus callosum, and abnormalities of the posterior fossa. Fetal MRI is also increasingly performed to evaluate fetuses who have normal brain findings on prenatal sonogram but who are at increased risk for neurodevelopmental abnormalities, such as complicated monochorionic twin pregnancies. This paper will briefly discuss the common clinical conditions imaged by fetal MRI as well as recent advances in fetal MRI research. (orig.)

    Piracetam is thought to promote the metabolism of brain cells when they are hypoxic. It has been used to prevent adverse effects of fetal distress. The objective of this review was to assess the effects of piracetam for suspected fetal distress in labour on method of delivery and perinatal morbidity. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (15 February 2012). Randomised trials of piracetam compared with placebo or no treatment for suspected fetal distress in labour. Both review authors assessed eligibility and trial quality. One study of 96 women was included. Piracetam compared with placebo was associated with a trend to reduced need for caesarean section (risk ratio 0.57, 95% confidence interval 0.32 to 1.03). There were no statistically significant differences between the piracetam and placebo group for neonatal morbidity (measured by neonatal respiratory distress) or Apgar score. There is not enough evidence to evaluate the use of piracetam for fetal distress in labour.

    The admission cardiotocograph (CTG) is a commonly used screening test consisting of a short (usually 20 minutes) recording of the fetal heart rate (FHR) and uterine activity performed on the mother's admission to the labour ward. This is an update of a review published in 2012. To compare the effects of admission cardiotocography with intermittent auscultation of the FHR on maternal and infant outcomes for pregnant women without risk factors on their admission to the labour ward. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register to 30 November 2016 and we planned to review the reference list of retrieved papers All randomised and quasi-randomised trials comparing admission CTG with intermittent auscultation of the FHR for pregnant women between 37 and 42 completed weeks of pregnancy and considered to be at low risk of intrapartum fetal hypoxia and of developing complications during labour. Two authors independently assessed trial eligibility and quality, and extracted data. Data were checked for accuracy. We included no new trials in this update. We included four trials involving more than 13,000 women which were conducted in the UK and Ireland and included women in labour. Three trials were funded by the hospitals where the trials took place and one trial was funded by the Scottish government. No declarations of interest were made in two trials; the remaining two trials did not mention declarations of interest. Overall, the studies were assessed as low risk of bias. Results reported in the 2012 review remain unchanged.Although not statistically significant using a strict P auscultation (risk ratio (RR) 1.20, 95% confidence interval (CI) 1.00 to 1.44, 4 trials, 11,338 women, I² = 0%, moderate quality evidence). There was no clear difference in the average treatment effect across included trials between women allocated to admission CTG and women allocated to intermittent auscultation in instrumental vaginal birth (RR 1.10, 95% CI 0.95 to 1

    Normal fetal brain maturation can be studied by in vivo magnetic resonance imaging (MRI) from the 18th gestational week (GW) to term, and relies primarily on T2-weighted and diffusion-weighted (DW) sequences. These maturational changes must be interpreted with a knowledge of the histological background and the temporal course of the respective developmental steps. In addition, MR presentation of developing and transient structures must be considered. Signal changes associated with maturational processes can mainly be ascribed to the following changes in tissue composition and organization, which occur at the histological level: (1) a decrease in water content and increasing cell-density can be recognized as a shortening of T1- and T2-relaxation times, leading to increased T1-weighted and decreased T2-weighted intensity, respectively; (2) the arrangement of microanatomical structures to create a symmetrical or asymmetrical environment, leading to structural differences that may be demonstrated by DW-anisotropy; (3) changes in non-structural qualities, such as the onset of a membrane potential in premyelinating axons. The latter process also influences the appearance of a structure on DW sequences. Thus, we will review the in vivo MR appearance of different maturational states of the fetal brain and relate these maturational states to anatomical, histological, and in vitro MRI data. Then, the development of the cerebral cortex, white matter, temporal lobe, and cerebellum will be reviewed, and the MR appearance of transient structures of the fetal brain will be shown. Emphasis will be placed on the appearance of the different structures with the various sequences. In addition, the possible utility of dynamic fetal sequences in assessing spontaneous fetal movements is discussed

    1985-12-01

    Twenty-four pregnant women carrying 26 fetuses (two sets of twins) were imaged with magnetic resonance (MR) imaging at 0.35 T following sonographic evaluation. Each study was retrospectively evaluated to determine which of 33 normal fetal structures were visible on the images and which imaging parameters were most useful for depicting fetal anatomy. Fetal motion degraded fetal images in all but two cases, both with oligohydramnios and in the third trimester of gestation. Nevertheless, many fetal structures were identifiable, particularly in the third trimester. Visualization of fetal anatomy improved with intravenous maternal sedation in five cases. Relatively T1-weighted images occasionally offered the advantage of less image degradation owing to fetal motion and improved contrast between different fetal structures. More T2 weighting was believed to be advantageous in one case for outlining the fetal head and in one case for delineation of the brain. In many cases, structures were similarly identifiable (though with different signal intensities) regardless of the parameters selected. The authors conclude that MR imaging of many fetal structures is currently unsatisfactory and is probably of limited value, particularly in the first and second trimesters. However, the relative frequency and detail with which the fetal head and liver can be depicted indicate that these may be areas for further investigation, and the potential utility of imaging fetal fat warrants further investigation.

    stress during pregnancy can have adverse effects on the course of pregnancy and on fetal development. There are few studies investigating the outcome of stress reduction interventions on maternal well-being and obstetric outcome. this study aims (1) to obtain fetal behavioral states (quiet/active sleep, quiet/active wakefulness), (2) to investigate the effects of maternal relaxation on fetal behavior as well as on uterine activity, and (3) to investigate maternal physiological and endocrine parameters as potential underlying mechanisms for maternal-fetal relaxation-transferral. the behavior of 33 fetuses was analyzed during laboratory relaxation/quiet rest (control group, CG) and controlled for baseline fetal behavior. Potential associations between relaxation/quiet rest and fetal behavior (fetal heart rate (FHR), FHR variation, FHR acceleration, and body movements) and uterine activity were studied, using a computerized cardiotocogram (CTG) system. Maternal heart rate, blood pressure, cortisol, and norepinephrine were measured. intervention (progressive muscle relaxation, PMR, and guided imagery, GI) showed changes in fetal behavior. The intervention groups had higher long-term variation during and after relaxation compared to the CG (p=.039). CG fetuses had more FHR acceleration, especially during and after quiet rest (p=.027). Women in the PMR group had significantly more uterine activity than women in the GI group (p=.011) and than CG women. Maternal heart rate, blood pressure, and stress hormones were not associated with fetal behavior. this study indicates that the fetus might participate in maternal relaxation and suggests that GI is superior to PMR. This could especially be true for women who tend to direct their attention to body sensations such as abdominal activity. 2010 Elsevier Ltd. All rights reserved.

    To present a measure of effective workplace organizational policies, programs, and practices that focuses on working conditions and organizational facilitators of worker safety, health and well-being: the workplace integrated safety and health (WISH) assessment. Development of this assessment used an iterative process involving a modified Delphi method, extensive literature reviews, and systematic cognitive testing. The assessment measures six core constructs identified as central to best practices for protecting and promoting worker safety, health and well-being: leadership commitment; participation; policies, programs, and practices that foster supportive working conditions; comprehensive and collaborative strategies; adherence to federal and state regulations and ethical norms; and data-driven change. The WISH Assessment holds promise as a tool that may inform organizational priority setting and guide research around causal pathways influencing implementation and outcomes related to these approaches.

  18. Clinical implications from monitoring fetal activity.

    Rayburn, W F

    1982-12-15

    The monitoring of fetal motion in high-risk pregnancies has been shown to be worthwhile in predicting fetal distress and impending fetal death. The maternal recording of perceived fetal activity is an inexpensive surveillance technique which is most useful when there is chronic uteroplacental insufficiency or when a stillbirth may be expected. The presence of an active, vigorous fetus is reassuring, but documented fetal inactivity required a reassessment of the underlying antepartum complication and further fetal evaluation with real-time ultrasonography, fetal heart rate testing, and biochemical testing. Fetal distress from such acute changes as abruptio placentae or umbilical cord compression may not be predicted by monitoring fetal motion. Although not used for routine clinical investigation, electromechanical devices such as tocodynamometry have provided much insight into fetal behavioral patterns at many stages of pregnancy and in pregnancies with an antepartum complication.

    To establish a structured review process to facilitate the identification of the fetal nasal bone (NB) in the first trimester ultrasound scan to improve the quality images. We conducted a retrospective observational study in fetal NB images obtained during ultrasound exams of singleton pregnancies that underwent first trimester screening (crown-rump length 45-84 mm). When the images were obtained the examiner was not aware of the study. Audit was conducted by an examiner according criteria established by the Fetal Medicine Foundation. Fetal NB images were assessed regarding adequate magnification, mid-sagittal view and transducer held parallel to the direction of the nose. The transvaginal and transabdominal as well as anterior and posterior fetal back groups were compared using χ(2) test. We considered 874 fetal NB images for auditing. Fetal NB was considered present in 865 images (99%). During the audit process, we identified 72 (8.2%) cases of disagreement between examiner and auditor assessments. Disagreement was higher when image quality was poor (62 cases = 7%). Transvaginal approach performed better in the following criteria: adequate magnification (p audit program for fetal NB is feasible in a clinical scenario. Image quality appears to play an important role in compliance to image standards audited and in agreement between examiner and auditor.

    Full Text Available We investigated the role of foetal spine position in the first and second labour stages to determine the probability of OPP detection at birth and the related obstetrical implications. We conducted an observational-longitudinal cohort study on uncomplicated cephalic single foetus pregnant women at term. We evaluated the accuracy of ultrasound in predicting occiput position at birth, influence of fetal spine in occiput position during labour, labour trend, analgesia request, type of delivery, and indication to CS. The accuracy of the foetal spinal position to predict the occiput position at birth was high at the first labour stage. At the second labour stage, CS (40.3% and operative vaginal deliveries (23.9% occurred more frequently in OPP than in occiput anterior position (7% and 15.2%, resp., especially in cases of the posterior spine. In concordant posterior positions labour length was greater than other ones, and analgesia request rate was 64.1% versus 14.7% for all the others. The assessment of spinal position could be useful in obstetrical management and counselling, both before and during labour. The detection of spinal position, more than OPP, is predictive of successful delivery. In concordant posterior positions, the labour length, analgesia request, operative delivery, and caesarean section rate are higher than in the other combination.

    The aim of this study was to assess the value of fetal skeletal radiographs in determining the etiology of fetal death. A total of 1193 post-mortem fetal skeletal radiographs were analysed. Fetuses were classified into one of three groups (group I: abnormality diagnosed during pregnancy; group II: maternal pathology; group III: spontaneous abortion of pregnancy, IIIa before 26 weeks of gestation (WG), IIIb after 26 weeks of gestation). Face, supine and lateral skeletal views were performed. Skeletal abnormalities were detected in 33.9% of the fetuses, including 22.7% with minor abnormalities (abnormal rib number, no nasal bone ossification, amesophalangia or P2 hypoplasia of the fifth digit) and 14.5% with major abnormalities (other skeletal abnormalities). Among the fetuses with major abnormalities, 98.8% came from group I, 2.9% came from group II, 2.3% came from group IIIa and none came from group IIIb. Fetal skeletal radiographs are not useful in fetuses arising from spontaneous abortion of pregnancy without abnormality on ultrasound screening, abnormality clinical examination or in fetuses with prenatal diagnosis of chromosomal abnormality. This practice is valuable only if there is a multidisciplinary team, with all the participants (pathologists, radiologists, geneticists) knowledgeable about fetal pathology. In the absence of this multidisciplinary approach, it is easier to X-ray all fetuses to avoid misdiagnosis and the important consequences for genetic counselling. (orig.)

    To construct reference ranges for fetal pH, oxygen pressure (PO2), and hematologic and biochemical blood constituents, which can be used to analyze changes with gestation and differences with maternal values, thus elucidating some aspects of fetal biology and the effects of the maternal and placental environments. We assayed venous pH, PO2, hematocrit, glucose, uric acid, urea, creatinine, total protein, total and direct bilirubin, aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltransferase, alkaline phosphatase, lactic dehydrogenase, amylase, pseudocholinesterase, creatine kinase, triglycerides, and cholesterol concentrations in 157 fetuses and 134 mothers who underwent fetal blood sampling from 18 to 37 weeks' gestation. None of the fetuses was infected or had chromosomal, hematologic, or hormonal abnormalities. All the variables analyzed were similar in fetuses sampled at the placental cord insertion (n = 125) or at the intrahepatic vein (n = 32). Maternal and fetal concentrations of glucose (r = 0.79, P PO2 decreased with gestational age, whereas hematocrit increased, similar to what has been described previously. All of the other variables, with the exception of amylase and cholesterol, changed significantly during the investigated period of pregnancy. Gestational age explained at least 40% of the variance in values of fetal total protein, pseudocholinesterase, alanine aminotransferase, creatine kinase, and triglycerides, but only 3-25% of the variation in the remainder. Most enzymes were higher in the fetus than in the maternal circulation, and all except alkaline phosphatase increased with gestational age. The maternal-fetal glucose difference correlated significantly with hematocrit, pH, and PO2, independent of gestational age and independent of each other.

    As people lead longer and generally healthier lives, aspirations and expectations of health care extend to include well-being and enhanced quality of life. Several measurement scales exist to evaluate how well health care reaches these goals. However, the definitions of well-being or quality of life remain open to considerable debate, which complicates the design, validation, and subsequent choice of an appropriate measurement. This article reviews nine measures of psychological well-being, tracing their origins in alternative conceptual approaches to defining well-being. It compares their psychometric properties and suggests how they may be used. The review covers the Life Satisfaction Index, the Bradburn Affect Balance Scale, single-item measures, the Philadelphia Morale scale, the General Well-Being Schedule, the Satisfaction With Life scale, the Positive and Negative Affect Scale, the World Health Organization 5-item well-being index, and the Ryff's scales of psychological well-being. Scales range in size from a single item to 22; levels of reliability and validity range from good to excellent, although for some of the newer scales we lack information on some forms of validity. Measures exist to assess several conceptions of psychological well-being. Most instruments perform adequately for survey research, but we know less about their adequacy for use in evaluating health care interventions. There remains active debate over how adequately the questions included portray the theoretical definition of well-being on which they are based. Copyright (c) 2010 Elsevier Inc. All rights reserved.

  6. Evaluation of the fetal abdomen by magnetic resonance imaging. Part 2: abdominal wall defects and tumors

    Full Text Available Abstract Although ultrasound is still the gold standard for the assessment of fetal malformations, magnetic resonance imaging (MRI has gained great prominence in recent years. In situations in which ultrasound has low sensitivity, such as maternal obesity, abdominal scarring, and oligohydramnios, MRI has proven to be a safe and accurate method. Regarding fetal abdominal wall defects, MRI appears to be widely used in the prognostic assessment of gastroschisis with intestinal atresia or of complications of omphalocele, allowing better perinatal management and parental counseling. In addition, MRI allows the assessment of local invasion of fetal abdominal tumors, with significant prognostic value for the postnatal period. In this article, we review the main MRI findings in the evaluation of fetal abdominal wall defects and tumors.

    Full Text Available There are few congenital anomalies that can be treated in utero, despite the rapid development of fetal medicine. The number of available antenatal treatments is growing with the advance of supplementary tools, especially ultrasound and endoscopy. Disorders involving accumulation of excessive fluid in the amniotic cavity (polyhydramnios, chest (hydrothorax, abdomen (ascites and urinary system (obstructive uropathy are regularly treated using aspiration or shunt drainage under ultrasound monitoring. Electrolyte solutions or concentrated blood component supplements are used to treat oligohydramnios (amnioinfusion and amniopatch and fetal anemia (fetal transfusion. Placental tumor (chorioangioma and fetal tumors (cystic hygroma and sacrococcygeal teratoma are also successfully treated by antenatal injection of medications. Fetoscopic procedures, especially obstetric endoscopy, are now used regularly in North America, Europe, Australasia and Japan after the validity was established in the treatment of twin-twin transfusion syndrome when compared with traditional amnioreduction. However, most procedures involving surgical fetoscopy or open fetal surgery remain experimental. Their validity and efficacy are not confirmed in a number of fetal diseases for which they were claimed to be effective. A brief review of the global status and history of invasive fetal therapy is given, and its status in Taiwan is also described. Future development in this field relies on greater understanding of the basic physiology and pathology of the diseases involved, as well as on the progress of sophisticated instrumentation.

    that octreotide treatment in pregnancy, as well as hypoglycemia in itself, may pose a risk of fetal growth restriction. During pregnancy, management of blood glucose levels in familial hyperinsulinemic hypoglycemia thus forms a medical dilemma. We report on pregnancy outcomes in a woman with symptomatic familial...... hyperinsulinemic hypoglycemia, type 3. During the patient's first pregnancy with a viable fetus octreotide treatment was instituted in gestational age 23 weeks to prevent severe hypoglycemic incidences. Fetal growth velocity declined, and at 37 weeks of gestation, intrauterine growth retardation was evident...... growth velocity was normal. We conclude that octreotide treatment during pregnancy may pose a risk of fetal growth restriction and warrants careful consideration. In some cases of familial hyperinsulinemic hypoglycemia, blood glucose levels can be successfully managed through diet only, also during...

  9. Well-being, capabilities and philosophical practice

    2014-01-01

    Full Text Available The concept of well being has become the main criterion to assess quality of life in contemporary society. Individual well-being describes the individual quality of life, while social well-being refers to quality of life in a society. Given that well-being has a multitude of dimensions, a unique definition of it is elusive to scholars. In this article social well-being is conceptualised as a dynamic process within the context set by social integration as one’s relationship to society and the community. This includes the quality of interaction between the individual and society and one’s ‘social actualisation’ understood as the realisation of one’s social capacities. Social actualisation also involves one’s ability to influence social processes and to benefit from social cohesion, which consists, in any society, of the quality, organisation and functioning of the social world. Hence the ability to impact society is an integral part of individual well being. This paper suggests that philosophical practice as a new paradigm in the humanities holds out promise for the improvement of both individual and social well-being.

    Purpose: To review our experience with fetal magnetic resonance imaging (MRI) to evaluate congenital heart disease (CHD). Methods: We performed fetal MRI in 32 fetuses with an echocardiographically assessed CHD. Both direct and indirect signs of CHD were investigated. Direct signs considered were: morpho-volumetric abnormalities of the heart; malrotations; ventricular and atrial septal defects; anomalies of the origin, size and course of the great arteries. Indirect signs considered were: difficulty to recognize a 'normal' anatomical structures in the reference projections; increase of the vascular size before a stenosis; hypertrophy of the papillary muscles; cardiomegaly and pericardial effusion. All MRI findings were compared with postnatal or autoptic findings. Results: MRI allowed the CHD to be visualised by direct signs in 17 fetuses, indirect signs in 5 and both direct and indirect signs in 9 fetuses, excluding the prenatal echocardiographic suspect of hypoplastic left heart syndrome in 1 fetus. Postnatal echocardiograms or autoptic findings confirmed a normal heart in 1 fetus and CHD in 31 fetuses including a single cardiac anomaly or syndrome in 19 fetuses, 2 associated cardiac abnormalities in 11 and 3 cardiac anomalies in 1 fetus. However, in 2 fetuses MRI detected a ventricular septal defect successively disclosed by gold standard. Conclusions: MRI is a promising method for further assessment of the cardiovascular pathologies diagnosed by echocardiography, and may be a valuable tool in assessing associated extracardiac anomalies.

    The World Health Organization (WHO) has determined mental health in children to be a priority area for evidence-based interventions. Effective and efficient screening methods are needed to assess emotional well-being of children from diverse cultures. This descriptive study examined two tools for feasibility, sensitivity, cultural appropriateness, and cost/time effectiveness. Emotional well-being was conceptualized using the Roy Adaptation Model as part of the self-concept adaptive mode. Emotional indicators were measured from Human Figure Drawings. Anxiety was measured using a modification of the Revised Children's Manifest Anxiety Survey (RCMAS). The sample included 11 girls who were 7 to 12 years of age and recruited from a girls' orphanage in Honduras. Results indicated the Human Figure Drawings identified more children possibly at risk than the RCMAS. Human Figure Drawings were found to be a time/cost-effective, sensitive, and culturally appropriate means for measuring emotional well-being in the setting. This study contributes to nursing knowledge by demonstrating feasibility of the screening tools for measuring emotional well-being of children in varied cultures.

    Common fetal anomalies of the kidneys and urinary tract encompass a complex spectrum of abnormalities that can be detected prenatally by ultrasound. Common fetal anomalies of the kidneys and urinary tract can affect amniotic fluid volume production with the development of oligohydramnios or anhydramnios, resulting in fetal pulmonary hypoplasia and, potentially, abnormal development of other fetal structures. We provide an overview of common fetal anomalies of the kidneys and urinary tract with an emphasis on sonographic patterns as well as pathologic and postnatal correlation, along with brief recommendations for postnatal management. Of note, we render an updated classification of fetal abnormalities of the kidneys and urinary tract based on the presence or absence of associated urinary tract dilation. In addition, we review the 2014 classification of urinary tract dilation based on the Linthicum multidisciplinary consensus panel.

    Full Text Available OBJECTIVES: Amniotic fluid Volume (AFV is an important indicator of fetal well - being Oligohydramnios affects 0.5 to 5% of the pregnancy. In presence of Oligohydramnios if the AFI is 0 - 7 the fetal outcome is not good. If the AFI <5 which needs immediate delivery irrespective of the NST results. So the cases selected between AFI 0 - 7 a re directly taken to LSCS. To know the fetal outcome associated with Oligohydramnios (AFI 0 - 7. MATERIALS AND METHODS: This is a prospective study. The study group consisted of 67 pregnant cases selected from Vanivilas Hospital attached to Bangalore Medica l College and Research Institute, Bangalore. The cases were studied between the periods 15 th November 2014 to 1 st March 2015. These 67 in patients were selected for emergency OT directly because of variable AFI (0 - 7. Based on this fetal outcome is assesse d. The AFI was totally based on USG report on admission and these cases was referred from outside to Vanivilas Hospital because this hospital is a tertiary care center where emergency OT is working round the clock. RESULTS: Out of 67 cases in the present s tudy group there was not even one fetal mortality. The birth weight was varying from 1.4 kg to 3.2 kg out of these two babies needed stimulation after extraction in the OT their birth weight was 1.4 kg and 1.6 kg. There was meconium in 17 cases (thick meco nium 12 cases, thin meconium 5 cases. Anhydramnios (nil liquor 3 cases, NICU admissions (16. CONCLUSION: Oligohydramnios (AFI between 0 - 7 is an important indication for emergency LSCS without depending on NST which can result in good fetal outcome in a tertiary center like VVH. So the mortality and morbidity of the fetus can be avoided if we decide for emergency LSCS

    In South Dakota, the status of equid well being is relatively unknown. This study sought to (a) gain understanding about the current perceptions of nonhuman animal well being in South Dakota, with an emphasis on horses and other equids; (b) determine the level of care equids are reportedly receiving and the perceived challenges to equine well being in South Dakota, and (c) determine if people from diverse geographical locations (east or west of the Missouri River) have similar views on the well being of equids in South Dakota. Respondents indicated the current level of equid well being in South Dakota is sufficient, but there is room for improvement. Current challenges for the equid population of South Dakota were the high annual cost of horse care, poor horsemanship, dental problems, and whether caregivers understand basic equine care. Several significant associations arose between where a respondent lives (Western or Eastern South Dakota) and their level of agreement with various statements. The results provide a benchmark to gauge well being and help give direction for future educational needs that can continue to improve equid care.

    There is an increased risk of fetal goiter in patients who have a history of Grave's disease and undergo propylthiouracil (PTU) treatment during pregnancy. In this report, we describe a case of a fetal goiter detected by antenatal ultrasound at the 26th week of gestation in a mother treated with PTU for Grave's disease. A 32 x 38 x 20 mm fetal goiter was detected, each lobe measured 30 x 18 x 18 mm and estimated volume was 10 cm3. Subsequently, fetal thyroid function was assessed by umbilical fetal blood sampling. Cord blood showed elevated serum TSH (40.2 mU/l) and normal concentrations of free T4 (9.5 pmol/l) and free T3 (2.6 pmol/l). There were no other ultrasonographic signs of fetal hypothyroidism. Based on the above findings, the mother's PTU dosage was reduced to 50 mg daily from a total of 150 mg and weekly ultrasonographic examinations were performed. Six weeks after the initial ultrasound, a complete regression of the fetal goiter was noted. At the 34th week of gestation, the patient was delivered due to intrauterine growth restriction and oligohydramnios and gave birth to a male, weighing 1,920 g. The newborn thyroid was not palpable and thyroid ultrasonography was normal. Cord blood TSH was normal (8.4 mU/l) and free T4 was within lower normal limit (9.03 pmol/l). Ten days later, newborn thyroid function was normal and the baby did well afterwards. In conclusion, after the evaluation of fetal thyroid status, selected cases with fetal goiter can be initially managed without intrauterine treatment. (c) 2005 S. Karger AG, Basel

    We tested whether the cultural background of raters influenced ratings of chimpanzee personality. Our study involved comparing personality and subjective well-being ratings of 146 chimpanzees in Japan that were housed in zoos, research institutes, and a retirement sanctuary to ratings of chimpanzees in US and Australian zoos. Personality ratings were made on a translated and expanded version of a questionnaire used to rate chimpanzees in the US and Australia. Subjective well-being ratings were made on a translated version of a questionnaire used to rate chimpanzees in the US and Australia. The mean interrater reliabilities of the 43 original adjectives did not markedly differ between the present sample and the original sample of 100 zoo chimpanzees in the US. Interrater reliabilities of these samples were highly correlated, suggesting that their rank order was preserved. Comparison of the factor structures for the Japanese sample and for the original sample of chimpanzees in US zoos indicated that the overall structure was replicated and that the Dominance, Extraversion, Conscientiousness, and Agreeableness domains clearly generalized. Consistent with earlier studies, older chimpanzees had higher Dominance and lower Extraversion and Openness scores. Correlations between the six domain scores and subjective well-being were comparable to those for chimpanzees housed in the US and Australia. These findings suggest that chimpanzee personality ratings are not affected by the culture of the raters.

    Full Text Available Congenital heart diseases are encountered in 0.8% of live births and are among the most frequently diagnosed malformations. At least half of these anomalies end up with death or require surgical interventions and are responsible for 30% of the perinatal mortality. Fetal echocardiography is the sum of knowledge, skill and orientation rather than knowing the embryologic details of the fetal heart. The purpose of fetal echocardiography is to document the presence of normal fetal cardiac anatomy and rhythm in high risk group and to define the anomaly and arrhythmia if present. A certain sequence should be followed during the evaluation of fetal heart. Sequential segmental analysis (SSA and basic definition terminology made it possible to determine a lot of complex cardiac anomalies during prenatal period. By the end of 1970’s, Shinebourne started using sequential segmental analysis for fetal cardiac evaluation and today, prenatal diagnosis of congenital heart disease is possible without any confusion. In this manner, whole fetal heart can be evaluated as the relation of three segments (atria, ventricles and the great arteries with each other, irrelevant of complexity of a possible cardiac anomaly. Presence of increased nuchal thickness during early gestation and abnormal four-chamber-view during ultrasonography by the obstetrician presents a clear indication for fetal echocardiography,however, one should keep in mind that 80-90% of the babies born with a congenital heart disease do not have a familial or maternal risk factor. In addition, it should be remembered that expectant mothers with diabetes mellitus pose an indication for fetal echocardiography.

    To assess the value and complementary roles of fetal MRI and US for characterization and diagnosis of suprarenal masses. We conducted a multi-institutional retrospective database search for prenatally diagnosed suprarenal masses between 1999 and 2012 and evaluated the roles of prenatal US and fetal MRI for characterization and diagnosis, using postnatal diagnosis or surgical pathology as the reference standard. Prenatal US and fetal MRI were assessed for unique findings of each modality. The database yielded 25 fetuses (gestational age 20-37 weeks) with suprarenal masses. Twenty-one fetuses had prenatal US, 22 had MRI, 17 had both. Postnatal diagnoses included nine subdiaphragmatic extralobar sequestrations, seven adrenal hemorrhages, five neuroblastomas (four metastatic), two lymphatic malformations, one duplex kidney with upper pole cystic dysplasia, and one adrenal hyperplasia. Ultrasound was concordant with MRI for diagnoses in 12/17 (70.6%) cases. Discordant diagnoses between US and MRI included three neuroblastomas and two adrenal hemorrhages. In the three neuroblastomas US was equivocal and MRI was definitive for neuroblastoma, demonstrating heterogeneous, intermediate-signal solid masses and liver metastases. In the two cases of adrenal hemorrhage US was equivocal and MRI was definitive with signal characteristics of hemorrhage. In 2/4 neuroblastomas, Doppler US demonstrated a systemic artery suggesting extralobar sequestration; however MRI signal characteristics correctly diagnosed neuroblastoma. All cases of extralobar sequestration were correctly diagnosed by US and MRI. US and MRI both accurately detect suprarenal masses. MRI complements US in equivocal diagnoses and detects additional findings such as liver metastases in neuroblastoma. (orig.)

    The aim of this study was to determine whether hypoxemia induces an increase in plasma erythropoietin concentration in human fetal life and, if so, whether this response stimulates fetal erythropoiesis. The plasma erythropoietin concentration in blood samples from 33 small-for-gestational-age fetuses at 26 to 38 weeks' gestation was measured. Measurements were compared with the reference range for gestation, and associations with PO2, pH, and erythroblast and erythrocyte counts were examined. The mean plasma erythropoietin concentration in the small-for-gestational-age fetuses was significantly increased, and the degree of increase was significantly associated both with fetal acidemia and, more strongly, with fetal erythroblastosis. Erythropoietin production in response to tissue hypoxia occurs from at least 26 weeks' gestation with measurable physiologic effects on erythropoiesis. Furthermore, more accurate assessment of tissue oxygenation may be obtained by measuring the erythroblast count rather than the blood pH.

  1. On the Importance of Well-Being

    2008-01-01

    Many among philosophers and non-philosophers would claim that well-being is important in moral theory because it is important to the individual whose well-being it is. The exact meaning of this claim, however, is in need of clarification. Having provided that, I will present a charge against it...... central theories in normative ethics. I will focus on Scanlon’s discussion in particular because it affords us with two criteria for the assessment of the importance for a person of a value-concept such as well-being. I will claim that much of Scanlon’s case rests on the idea that well......-being is an inclusive good, a good constituted by other things that are good in and for themselves. Then, I will put forward a case against Scanlon’s challenge by (1) showing that inclusiveness, when properly understood, does not lead to the conclusion Scanlon is led to and (2) showing that on at least the reading...

    Schulte, Paul; Vainio, Harri

    2010-09-01

    This paper provides an overview of and perspective on the concept of well-being at work. Well-being is a term that reflects not only on one's health but satisfaction with work and life. Well-being is a summative concept that characterizes the quality of working lives, including occupational safety and health (OSH) aspects, and it may be a major determinant of productivity at the individual, enterprise and societal levels. Based on a review of the literature and a recent conference, we suggest a model linking workforce well-being, productivity, and population well-being. To appraise the validity of the model, we consider five questions: (i) is there a robust and usable definition of workplace well-being? (ii) have the variables that influence well-being been aptly described and can they be measured and used in risk assessments? (iii) what is the nature of evidence that well-being is linked to productivity? (iv) what is the state of knowledge on the effectiveness of interventions to promote workplace well-being? and (v) should interventions aimed at improving well-being at work focus on more than work-related factors?

    Clear guidance on fetal growth assessment is important because of the strong links between growth restriction or macrosomia and adverse perinatal outcome in order to reduce associated morbidity and mortality. Fetal growth curves are extensively adopted to track fetal sizes from the early phases of pregnancy up to delivery. In the literature, a large variety of reference charts are reported but they are mostly up to five decades old. Furthermore, they do not address several variables and factors (e.g., ethnicity, foods, lifestyle, smoke, and physiological and pathological variables), which are very important for a correct evaluation of the fetal well-being. Therefore, currently adopted fetal growth charts are inadequate to support the melting pot of ethnic groups and lifestyles of our society. Customized fetal growth charts are needed to provide an accurate fetal assessment and to avoid unnecessary obstetric interventions at the time of delivery. Starting from the development of a growth chart purposely built for a specific population, in the paper, authors quantify and analyse the impact of the adoption of wrong growth charts on fetal diagnoses. These results come from a preliminary evaluation of a new open service developed to produce personalized growth charts for specific ethnicity, lifestyle, and other parameters.

    Electronic fetal monitoring (EFM) correlates poorly with neonatal outcome. We present a new metric: the "Fetal Reserve Index" (FRI), formally incorporating EFM with maternal, obstetrical, fetal risk factors, and excessive uterine activity for assessment of risk for cerebral palsy (CP). We performed a retrospective, case-control series of 50 term CP cases with apparent intrapartum neurological injury and 200 controls. All were deemed neurologically normal on admission. We compared the FRI against ACOG Category (I-III) system and long-term outcome parameters against ACOG monograph (NEACP) requirements for labor-induced fetal neurological injury. Abnormal FRI's identified 100% of CP cases and did so hours before injury. ACOG Category III identified only 44% and much later. Retrospective ACOG monograph criteria were found in at most 30% of intrapartum-acquired CP patients; only 27% had umbilical or neonatal pH <7.0. In this initial, retrospective trial, an abnormal FRI identified all cases of labor-related neurological injury more reliably and earlier than Category III, which may allow fetal therapy by intrauterine resuscitation. The combination of traditional EFM with maternal, obstetrical, and fetal risk factors creating the FRI performed much better as a screening test than EFM alone. Our quantified screening system needs further evaluation in prospective trials. © 2017 S. Karger AG, Basel.

    Fetal magnetic resonance imaging provides an ideal tool for investigating growth and development of the brain in vivo. Current imaging methods have been hampered by fetal motion but recent advances in image acquisition can produce high signal to noise, high resolution 3-dimensional datasets suitable for objective quantification by state of the art post acquisition computer programs. Continuing development of imaging techniques will allow a unique insight into the developing brain, more specifically process of cell migration, axonal pathway formation, and cortical maturation. Accurate quantification of these developmental processes in the normal fetus will allow us to identify subtle deviations from normal during the second and third trimester of pregnancy either in the compromised fetus or in infants born prematurely.

    Rayburn, W F

    1982-01-01

    This prospective investigation attempts to determine whether the maternal recording of perceived fetal motion is useful for fetal assessment in pregnancies complicated by hypertension. During a 21 month period, 124 patients whose pregnancies were complicated by either chronic or pregnancy-induced hypertension participated. The number of perceived movements per hour (24 +/- 11, mean +/- S.D.) and evidence for fetal inactivity (7 cases, 6%) did not vary significantly from a control group of normotensive pregnancies (p greater than 0.05). Fetal inactivity was predictive of an unfavorable perinatal outcome in 6 of 7 cases, including the three stillborn infants. No perinatal deaths occurred among the 117 hypertensive pregnancies with active fetuses, and the 6 cases with an unfavorable outcome were associated with mild intrauterine growth delay, prematurity, or acute changes such as placental abruption or umbilical cord accidents. Realizing these limitations, a record of fetal inactivity is worthwhile in managing the pregnancy complicated by hypertension.

This questionnaire is made of 57 items and has been applied to a sample of 770 people within the general population. The drawing-up process of the questionnaire is described to provide content validity. Items analysis was carried out together with exploratory and confirmatory factor analysis to assess the structure and construct validity of the tool. The extent of internal consistency (reliability) and concurrent validity has also been verified. DEBIE questionnaire (Spanish acronym for Aesthetic Dermatology and Emotional Well-being) revolves around six factors explaining 53.91% of the variance; there is a high level of internal consistency (Cronbach's α 0.90) and reasonable criterion validity. DEBIE questionnaire brings together adequate psychometric properties that can be applied to assess the perception that the general population have in relation to esthetic dermatology and its contribution to their emotional well-being. © 2014 Wiley Periodicals, Inc.

    Full Text Available Introduction. It is estimated that 3-10% of infants are growth restricted. Growth disturbances may have long-term issues. Doppler allows insight into the fetal response to intrauterine stress. Objective. The aim of this study was to detect fetal compromise in intrauterine growth-restricted (IUGR fetuses by means of biophysical profile (BPP vis-а-vis Doppler velocimetry studies of the fetal umbilical artery, and to find out which of the two is a better and earlier predictor of fetal compromise. Methods. A prospective study was conducted on a total of 50 singleton pregnancies with IUGR between 28 and 42 weeks of gestation. Study patients were managed expectantly with nonstress testing and amniotic fluid assessment, BPP and Doppler velocimetry studies of the fetal umbilical artery. Results. Fetal outcome was poor in 5/50 (10% of the fetuses, defined as presence of all of the following: poor Apgar test score, neonatal intensive care unit stay, necrotizing enterocolitis, and low birth weight. Of the four with abnormal BPP, 50% had poor fetal outcomes. Out of 46 with normal BPP, 6.5% had poor fetal outcomes. Conclusion. Inference drawn from the study is that the Doppler technology provides us the opportunity for repetitive noninvasive hemodynamic monitoring in IUGR pregnancies.

    To assess Malaysian dentists' perceptions of their mental well-being. A self-administered questionnaire was developed based on a conceptual framework of mental health and well-being model. Two aspects were assessed, namely the physiological (two domains) and the psychological (six domains). Participants were asked to rate their experiences of the aforementioned aspects using a 5-point Likert scale ranging from all the time to never. The response rate was 81%. Most of the dentists (61.7%) perceived having positive mental well-being. Under the physiological aspect, most respondents reported that they were 'generally happy' (93.3%), but about 30% stated they were 'stressed physically and emotionally'. Of the six domains under the psychological aspect, positive well-being was observed in the 'sense of coherence' and 'behavioural stress' domains. Participants who were above 40 years old, married and had children reported having a more positive mental well-being when compared with their counterparts. Overall, most Malaysian dentists perceived having a positive mental well-being. It is crucial, however, to closely monitor and initiate early interventions for those with negative symptoms to ensure the safe practice of dentistry.

    Since the introduction of fetal magnetic resonance imaging (MRI) into prenatal diagnostics, advances in coil technology and development of ultrafast sequences have further enhanced this technique. At present numerous sequences are available to visualize the whole fetus with high resolution and image quality, even in late stages of pregnancy. Taking into consideration the special circumstances of examination and adjusting sequence parameters to gestational age, fetal anatomy can be accurately depicted. The variety of sequences also allows further characterization of fetal tissues and pathologies. Fetal MRI not only supplies additional information to routine ultrasound studies, but also reveals fetal morphology and pathology in a way hitherto not possible. (orig.) [German] Seit Einfuehrung der fetalen Magnetresonanztomographie (MRT) in die praenatale Diagnostik wurde das Verfahren durch neue Spulentechniken und die Entwicklung ultraschneller Sequenzen kontinuierlich weiter entwickelt. Gegenwaertig steht eine Vielzahl von Sequenzen zur Verfuegung, die es erlauben, mit hoher Bildqualitaet und raeumlicher Aufloesung selbst in fortgeschrittenen Schwangerschaftsstadien den gesamten Feten darzustellen. Unter Beruecksichtigung der speziellen Untersuchungsbedingungen und des Schwangerschaftsalters kann so die fetale Anatomie genau abgebildet werden. Die Vielfalt an Sequenzen und deren gezielter Einsatz ermoeglichen es weiter, fetale Gewebe und Pathologien naeher zu charakterisierten. Auf diese Weise liefert die fetale MRT nicht nur Zusatzinformationen zur Routineultraschalluntersuchung, sie gibt auch Aufschluss ueber bestimmte fetale Morphologien und Pathologien, die bisher nicht darstellbar waren.

    Fetal demise is an uncommon event encountered at MR imaging. When it occurs, recognition by the interpreting radiologist is important to initiate appropriate patient management. To identify MR findings of fetal demise. Following IRB approval, a retrospective search of the radiology fetal MR database was conducted searching the words ''fetal demise'' and ''fetal death.'' Fetuses with obvious maceration or no sonographic confirmation of death were excluded. Eleven cases formed the study group. These were matched randomly to live fetuses of similar gestational age. Images were reviewed independently by three pediatric radiologists. The deceased fetus demonstrates decreased MR soft-tissue contrast and definition of tissue planes, including loss of gray-white matter differentiation in the brain. The signal within the cardiac chambers, when visible, is bright on HASTE sequences from the stagnant blood; the heart is small. Pleural effusions and decreased lung volumes may be seen. Interestingly, the fetal orbits lose their anatomical round shape and become smaller and more elliptical; a dark, irregular rim resembling a mask may be seen. Although fetal demise is uncommonly encountered at MR imaging, radiologists should be aware of such imaging findings so prompt management can be instituted. (orig.)

    Objective: To investigate fetal left ventricular function in hypertensive disorder of pregnancy (HDP). Methods: Fetuses of hypertensive (84) and normotensive (147) mothers were enrolled in this study. The fetal left ventricular ejection fractions, E/A ratios of mitral valves, left atrial shortening fractions and Tei indexes of the two groups were measured on fetal echocardiography. Results: The left ventricular ejection fractions (P=0.040), E/A ratios of the mitral valves (P=0.042) and the left atrial shortening fractions (P=0.036) in fetuses of HDP were significantly smaller than those of the normal group whereas the Tei indexes (P=0.030) were significantly larger than those of the normal group. Conclusion: The hypertensive disorder of pregnancy may cause decreased systolic, diastolic and global function of the fetal left ventricle. (authors)

    Full Text Available Ultrasound is an integral part of obstetric practice, and assessment of gestational age (GA is a central element of obstetric ultrasonography. Sonographic estimation of GA is derived from calculations based on fetal measurements. Numerous equations for GA calculation from fetal biometry have been adopted in routine practice. This study reports a new method of estimating GA in the second and third trimester using interischial distance (IID, the distance between the two ischial primary ossification centers, on fetal ultrasound. Four hundred women with uncomplicated normal singleton pregnancies from 16 weeks to term were examined. Standard fetal obstetric ultrasound was done measuring biparietal diameter (BPD and femur length (FL for each fetus. The IID, in millimeters, was correlated with the GA in weeks based upon the BPD and FL individually, and the BPD and FL together. Statistical analysis showed strong correlation between the IID and GA calculated from the FL with correlation coefficient (r =0.989, P < 0.001. Strong linear correlation was also found between the IID and GA based upon BPD and BPD+FL. Further statistical analysis using regression equations also showed that the IID was slightly wider in female fetuses, but this difference was not statistically significant. Resulting from this analysis, we have arrived at an easy-to-use equation: GA Weeks = (IID mm + 8 ±1 week. We feel this method can be especially applicable in the developing world, where midwives may not have access to software for fetal biometry in their basic handheld ultrasound machines. Even more sophisticated machines may not come with loaded software for obstetrics analysis. There are several limitations to this study, discussed below. We recommend further studies correlating the IID with other biometric parameters.

    Identification of health-related risk behaviors associated with well-being in college students is essential to guide the development of health promotion strategies for this population. The purposes were to evaluate well-being among undergraduate students and to identify health-related risk behaviors that predict well-being in this population. A cross-sectional Web-based survey of undergraduate students was conducted at a metropolitan university in the Southeast United States. A total of 568 students responded (response rate 14.2%). Data were collected on health-related risk behaviors using the National College Health Assessment II. Controlling demographic characteristics, the best predictive model included physical activity, current tobacco user, depression, ever received mental health services, and sleep quality, which was the strongest predictor (β = .45, p college students may be most beneficial in improving well-being.

    This review deals with the in vivo magnetic resonance imaging (MRI) appearance of the human fetal abdomen. Imaging findings are correlated with current knowledge of human fetal anatomy and physiology, which are crucial to understand and interpret fetal abdominal MRI scans. As fetal MRI covers a period of more than 20 weeks, which is characterized not only by organ growth, but also by changes and maturation of organ function, a different MR appearance of the fetal abdomen results. This not only applies to the fetal intestines, but also to the fetal liver, spleen, and adrenal glands. Choosing the appropriate sequences, various aspects of age-related and organ-specific function can be visualized with fetal MRI, as these are mirrored by changes in signal intensities. Knowledge of normal development is essential to delineate normal from pathological findings in the respective developmental stages

    Sansone, Randy A; Sansone, Lori A

    2010-11-01

    The word "gratitude" has a number of different meanings, depending on the context. However, a practical clinical definition is as follows-gratitude is the appreciation of what is valuable and meaningful to oneself; it is a general state of thankfulness and/or appreciation. The majority of empirical studies indicate that there is an association between gratitude and a sense of overall well being. However, there are several studies that indicate potential nuances in the relationship between gratitude and well being as well as studies with negative findings. In terms of assessing gratitude, numerous assessment measures are available. From a clinical perspective, there are suggested therapeutic exercises and techniques to enhance gratitude, and they appear relatively simple and easy to integrate into psychotherapy practice. However, the therapeutic efficacy of these techniques remains largely unknown. Only future research will clarify the many questions around assessment, potential benefits, and enhancement of gratitude.

    This study investigated the longitudinal relation between general well-being and self-esteem of male adolescents with severe psychiatric disorders. Moreover, the transition out of secure residential care was studied. Adolescents ( N = 172) were assessed three times with 6 months between each assessment. The sample comprised adolescents who were admitted throughout the entire study ( n = 116) and who had been discharged at 6/12 months follow-up ( n = 56). General well-being and self-esteem were stable concepts over time. The relation between general well-being and self-esteem differed for both groups. Among the admitted group general well-being positively predicted self-esteem and self-esteem negatively predicted general well-being from Time 2 to Time 3. Among the discharged adolescents, self-esteem at Time 1 positively predicted general well-being at Time 2 and general well-being at Time 2 positively predicted self-esteem at Time 3. Changing social contexts, as well as problems experienced during the transition out of secure care, might affect this relationship.

    Our aim was to assess the strength of the controversial association between thrombophilia and fetal loss, and to examine whether it varies according to the timing or definition of fetal loss. We searched Medline and Current Contents for articles published between 1975 and 2002 and their references with terms denoting recurrent fetal and non-recurrent fetal loss combined with various thrombophilic disorders. We included in our meta-analysis case-control, cohort, and cross-sectional studies published in English, the methodological quality of which was rated as moderate or strong. Pooled odds ratios (OR) with 95% CI were generated by random effects models with Cochrane Review Manager software. We included 31 studies. Factor V Leiden was associated with early (OR 2.01, 95% CI 1.13-3.58) and late (7.83, 2.83-21.67) recurrent fetal loss, and late non-recurrent fetal loss (3.26, 1.82-5.83). Exclusion of women with other pathologies that could explain fetal loss strengthened the association between Factor V Leiden and recurrent fetal loss. Activated protein C resistance was associated with early recurrent fetal loss (3.48, 1.58-7.69), and prothrombin G20210A mutation with early recurrent (2.56, 1.04-.29) and late non-recurrent (2.30, 1.09-4.87) fetal loss. Protein S deficiency was associated with recurrent fetal loss (14.72, 0.99-218.01) and late non-recurrent fetal loss (7.39, 1.28-42.63). Methylenetetrahydrofolate mutation, protein C, and antithrombin deficiencies were not significantly associated with fetal loss. The magnitude of the association between thrombophilia and fetal loss varies, according to type of fetal loss and type of thrombophilia.

    Assessing fetal cerebral biometry is one means of ascertaining that the development of the fetal central nervous system is normal. Norms have been established on large cohorts of fetuses by sonographic and neurofetopathological studies. Biometric standards have been established in MR in much smaller cohorts. The purpose of this paper is to analyse methods of measuring a few parameters in MR [biparietal diameter (BPD), fronto-occipital diameter (FOD), length of the corpus callosum (LCC), atrial diameter, transverse cerebellar diameter, height, anteroposterior diameter and surface of the vermis] and to compare US and MR in the assessment of fetal cerebral biometry.

    Spirituality can be defined as a personal search for meaning and purpose in life that may or may not encompass religion. In this article we report on the development and testing of an instrument for measuring spiritual well-being within a sample of haemodialysis patients. The main instrument, a 21-item Meaning in Life Scale (MiLS), comprises four scales: Life Perspective, Purpose and Goals, Confusion and Lessened Meaning, Harmony and Peace, and Benefits of Spirituality. A total score for spiritual well-being is also produced. We also used the following variables: clinical (time on haemodialysis, modified Charlson comorbidity index), sociodemographic (age, gender), and self-assessments of health, quality of life (general and recent), personal happiness, religiosity, and belief in the afterlife. A cross-sectional study was carried out on 94 haemodialysis patients. This study demonstrates that the MiLS-Sp is a psychometrically sound measure of spiritual well-being for dialysis patients (reliability, validity) as they manage the complex demands of a chronic illness. Spiritual well-being was significantly associated with various quality of life variables, health status, personal happiness, or religiosity in patients on dialysis. There was no relationship between spirituality scores and comorbidity, HD duration, gender, or age. Spiritual well-being is relatively low in dialysis patients. Spirituality may play an important role on psychological well-being, quality of life, and self-rated health for patients on haemodialysis. Spiritual well-being in these patients is relatively low. Results suggest that assessing and addressing spiritual well-being in dialysis patients may be helpful in clinical practice.

    We sought to synthesize a comprehensive literature review comprising recent research linking fetal programming to fetal telomere length. We also explored the potential effects fetal telomere length shortening has on fetal phenotypes. Utilizing the PubMed database as our primary search engine, we retrieved and reviewed 165 articles of published research. The inclusion criteria limited the articles to those that appeared within the last ten years, were pertinent to humans, and without restriction to language of publication. Our results showed that socio-demographic factors like age, sex, genetic inheritance, and acquired disease impact telomere length. Further, we found several maternal characteristics to be associated with fetal telomere length shortening, and these include maternal chemical exposure (eg, tobacco smoke), maternal stress during pregnancy, maternal nutritional and sleeping disorders during pregnancy as well as maternal disease status. Due to paucity of data, our review could not synthesize evidence directly linking fetal phenotypes to telomere length shortening. Although the research summarized in this review shows some association between determinants of intrauterine programming and fetal telomere length, there is still significant work that needs to be done to delineate the direct relationship of telomere attrition with specific fetal phenotypes. © 2017 John Wiley & Sons A/S.

    Full Text Available Recent developments in molecular genetics improved our knowledge on fetal genome and physiology. Novel scientific innovations in prenatal diagnosis have accelerated in the last decade changing our vision immensely. Data obtained from fetal genomic studies brought new insights to fetal medicine and by the advances in fetal DNA and RNA sequencing technology novel treatment strategies has evolved. Non-invasive prenatal diagnosis found ground in genetics and the results are widely studied in scientific arena. When Lo and colleges proved fetal genetic material can be extracted from maternal plasma and fetal DNA can be isolated from maternal serum, the gate to many exciting discoveries was open. Microarray technology and advances in sequencing helped fetal diagnosis as well as other areas of medicine. Today it is a very crucial prerequisite for physicians practicing prenatal diagnosis to have a profound knowledge in genetics. Prevailing practical use and application of fetal genomic tests in maternal and fetal medicine mandates obstetricians to update their knowledge in genetics. The purpose of this review is to assist physicians to understand and update their knowledge in fetal genetic testing from maternal blood, individualized prenatal counseling and advancements on the subject by sharing our experiences as İstanbul University Fetal Nucleic Acid Research Group.

    Life transitions are associated with high levels of stress affecting health behaviours among people with Type 1 diabetes. Transition to motherhood is a major transition with potential complications accelerated by pregnancy with risks of adverse childbirth outcomes and added anxiety and worries about pregnancy outcomes. Further, preparing and going through pregnancy requires vigilant attention to a diabetes management regimen and detailed planning of everyday activities with added stress on women. Psychological and social well-being during and after pregnancy are integral for good pregnancy outcomes for both mother and baby. The aim of this study is to establish the face and content validity of two novel measures assessing the well-being of women with type 1 diabetes in their transition to motherhood, 1) during pregnancy and 2) during the postnatal period. The approach to the development of the Pregnancy and Postnatal Well-being in T1DM Transition questionnaires was based on a four-stage pre-testing process; systematic overview of literature, items development, piloting testing of questionnaire and refinement of questionnaire. The questionnaire was reviewed at every stage by expert clinicians, researchers and representatives from consumer groups. The cognitive debriefing approach confirmed relevance of issues and identified additional items. The literature review and interviews identified three main areas impacting on the women's postnatal self-management; (1) psychological well-being; (2) social environment, (3) physical (maternal and fetal) well-being. The cognitive debriefing in pilot testing of the questionnaire identified that immediate postnatal period was difficult, particularly when the women were breastfeeding and felt depressed. The questionnaires fill an important gap by systematically assessing the psychosocial needs of women with type 1 diabetes during pregnancy and in the immediate postnatal period. The questionnaires can be used in larger data

    Twenty pregnant women underwent MR imaging (0.5 T) after US disclosed a significant fetal anomaly. The ability of MR imaging to depict the abnormalities was assessed. Of 20 abnormalities, 17 were visualized with MR imaging. Abnormalities included conjoined twins, omphalocele, gastroschisis, hydrocephalus, hydronephrosis, fetal ascites, facial teratoma, anencephaly, bladder outlet obstruction, thanatophoric dwarfism, cystic, hygroma, and fetal ovarian cyst. Thirteen of 14 abnormalities in third-trimester fetuses were visualized, as were four of six abnormalities in second-trimester fetuses. Associated polyhydramnios or oligohydramnios was evident in six of six cases. Anomalies were best delineated with T1-weighted sequences. The study suggests that MR imaging is potentially useful as a complementary imaging modality in the evaluation of fetal anomalies

    To compare utility of employee well-being to health risk assessment (HRA) as predictors of productivity change. Panel data from 2189 employees who completed surveys 2 years apart were used in hierarchical models comparing the influence of well-being and health risk on longitudinal changes in presenteeism and job performance. Absenteeism change was evaluated in a nonexempt subsample. Change in well-being was the most significant independent predictor of productivity change across all three measures. Comparing hierarchical models, well-being models performed significantly better than HRA models. The HRA added no incremental explanatory power over well-being in combined models. Alone, nonphysical health well-being components outperformed the HRA for all productivity measures. Well-being offers a more comprehensive measure of factors that influence productivity and can be considered preferential to HRA in understanding and addressing suboptimal productivity.

    Evaluation of the lens, including cataractous changes, is often of paramount importance in the classification of fetal syndromes or forensic questions. On histology, the crystalline lens is - especially in fetal and infant eyes - an organ susceptible to numerous artifacts. Thus, the aim of our study was to study various factors (including fixatives) that might have an impact on lens histomorphology. Twenty eyes from ten fetuses (formalin fixation: n = 10, glutaraldehyde fixation: n = 10), matched for gestational age and abortion (spontaneous vs. induced), were investigated macroscopically and by light microscopy. Sections were stained with routine hematoxylin & eosin (H&E), and periodic acid schiff (PAS). The age of the fetal eyes ranged from 15 to 36 weeks of gestation. Lens artifacts were analyzed and compared to fetal and adult lenses with definitive cataractous changes. In addition, 34 eyes from 27 fetuses with trisomy 21 were investigated for lens changes. All lenses showed artifacts of varying extent, in particular globules, vacuoles, clefts, anterior/posterior capsular separation, subcapsular proteinaceous material, fragmentation of the lens capsule/epithelium, and a posterior umbilication. Glutaraldehyde-fixed lenses displayed less artifacts compared to those fixed in formalin. Slight differences in the appearance of artifacts were found dependent on the fixative (formaldehyde vs glutaraldehyde) and the kind of abortion (iatrogenous vs spontaneous). The gestational age did not have a significant influence on the type and extent of lens artifacts. The lenses from fetuses with trisomy 21 displayed similar lens artifacts with no specific findings. Alterations in fetal lens morphology are extremely frequent and variable. These artifacts have to be carefully taken into account when interpreting post-mortem findings. Thus, the postmortem diagnosis of a fetal cataract should be made with great caution, and should include, in adherence to our proposed

    Spirituality is recognized as an important component of health care practice with elderly people. Yet, discussion of the role it plays in elderly women on a day-to-day basis is minimal, and it is frequently not addressed in quality-of-life studies in this population. The purposes of this study were to describe the level of religious well-being and selected characteristics of religiosity in a sample of 114 non-institutionalized, largely rural elderly women (Mdn age = 75), as well as to identify the relationship between selected factors and the level of religious well-being. Descriptive research revealed a high level of religious well-being among the participants and significant positive correlation between religious well-being and the variables of social support and hope (p hope emerged as the single significant predictor of religious well-being (p religious activities, highly rated the value or influence of religious beliefs in their lives, and identified that religious beliefs become increasingly important with age. Conducting a comprehensive assessment and implementing focused interventions associated with religious well-being will strengthen the scope of health care practice for elderly women.

    Different profiles of the character dimensions of self-directedness, cooperativeness and self-transcendence result in different levels of wellbeing among adults. However, the influence of the multidimensional character profiles on adolescents' composite wellbeing remains unexplored. This study builds on previous studies with adults, and examines the linear and non-linear associations between the dimensions of the psychobiological model of personality and well-being in adolescents. Participated in this study 1540 adolescents (M = 15.44, SD = 1.731). Personality was assessed using the Temperament and Character Inventory (TCI). Well-being was evaluated in a composite perspective: satisfaction with social support, health-related quality of life, satisfaction with life and affect. Variable-centered and individual-centered analyses were performed. Self-directedness was strongly associated with all dimensions of affective and cognitive well-being regardless of the other two character traits. Cooperativeness was associated with non-affective well-being and with positive affect, but only when associated to elevation of Self-directedness and Self-transcendence. Self-Directedness and Cooperativeness explained 15.5% of the non-affective well-being variance. Self-Directedness and Self-Transcendence explained 10.4% of the variance in affective well-being. This study confirms the tendencies found in previous studies with adults from other societies, where each character dimension gives an independent contribution to well-being depending on the interactions with other Character dimensions. Also, this study highlights the importance of considering the non-linear influences of the character dimensions in understanding of adolescents' wellbeing. These results have strong implications for youth positive mental health promotion, including for school-based policies and practices. PMID:25610408

    Cohort from 1997 to 1999 to assess the association between paternal age and fetal death. Fathers of the pregnancies were identified by record linkage to population registers. The paternal age-related risks of fetal death and its components, early and late fetal loss, were estimated using survival......A possible detrimental paternal age effect on offspring health due to mutations of paternal origin should be reflected in an association between paternal age and fetal loss. The authors used data from a prospective study of 23,821 pregnant women recruited consecutively to the Danish National Birth...... analysis. Pregnancies fathered by a man aged 50 or more years (n = 124) had almost twice the risk of ending in a fetal loss compared with pregnancies with younger fathers (hazard ratio = 1.88, 95% confidence interval: 0.93, 3.82), after adjustment for maternal age, reproductive history, and maternal...

Study population: Pregnant women with a first or second trimester ultrasound scan performed at all public hospitals in Denmark are registered in the database. Main variables/descriptive data: Data on maternal characteristics, ultrasonic, and biochemical variables are continuously sent from the fetal medicine units' Astraia databases to the central database via web service. Information about outcome of pregnancy (miscarriage, termination, live birth, or stillbirth is received from the National Patient Register and National Birth Register and linked via the Danish unique personal registration number. Furthermore, results of all pre- and postnatal chromosome analyses are sent to the database. Conclusion: It has been possible to establish a fetal medicine database, which monitors first-trimester screening for chromosomal abnormalities and second-trimester screening for major fetal malformations with the input from already collected data. The database is valuable to assess the performance at a regional level and to compare Danish performance with international results at a national level.

    Background: Environmental volunteering can increase well-being, but environmental volunteer well-being has rarely been compared to participant well-being associated with other types of volunteering or nature-based activities. This paper aims to use a multidimensional approach to well-being to explore the immediately experienced and later remembered well-being of environmental volunteers and to compare this to the increased well-being of participants in other types of nature-based activities and volunteering. Furthermore, it aims to compare volunteer managers’ perceptions of their volunteers’ well-being with the self-reported well-being of the volunteers. Methods: Onsite surveys were conducted of practical conservation and biodiversity monitoring volunteers, as well as their control groups (walkers and fieldwork students, respectively), to measure general well-being before their nature-based activity and activity-related well-being immediately after their activity. Online surveys of current, former and potential volunteers and volunteer managers measured remembered volunteering-related well-being and managers’ perceptions of their volunteers’ well-being. Data were analysed based on Seligman’s multidimensional PERMA (‘positive emotion’, ‘engagement’, ‘positive relationship’, ‘meaning’, ‘achievement’) model of well-being. Factor analysis recovered three of the five PERMA elements, ‘engagement’, ‘relationship’ and ‘meaning’, as well as ‘negative emotion’ and ‘health’ as factors. Results: Environmental volunteering significantly improved positive elements and significantly decreased negative elements of participants’ immediate well-being, and it did so more than walking or student fieldwork. Even remembering their volunteering up to six months later, volunteers rated their volunteering-related well-being higher than volunteers rated their well-being generally in life.

    To assess the value of fetal heart rate (FHR) measurements in predicting spontaneous fetal loss in pregnancies scheduled for chorionic villus sampling (CVS). A prospective descriptive study. Two hospital departments of obstetrics and gynaecology in Israel. 114 women between 9 and 11 weeks gestation scheduled for chorionic villus sampling (CVS). Fetal heart rate was measured by transvaginal Doppler ultrasound and compared with a monogram established from 75 fetuses. Whenever a normal FHR was recorded, CVS was performed immediately. 106 women had a normal FHR and underwent CVS; two of these pregnancies ended in miscarriage. In five pregnancies no fetal heart beats could be identified and fetal death was diagnosed. In three pregnancies an abnormal FHR was recorded and CVS was postponed; all three pregnancies ended in miscarriage within 2 weeks. Determination of FHR correlated with crown-rump length could be useful in predicting spontaneous miscarriage before performing any invasive procedure late in the first trimester.

    Lung MRI volumetrics may be valuable for fetal assessment following early preterm premature rupture of the foetal membranes (pPROM). To evaluate the predictive value of MRI lung volumetrics after pPROM. Retrospective cohort study of 40 fetuses after pPROM in a large, tertiary, perinatal referral center. Fetuses underwent MRI lung volumetrics. Estimated lung volume was expressed as percentage of expected lung volume (our own normal references). Primary outcome was neonatal mortality due to respiratory distress before discharge from hospital. Gestational age range was 16-27 weeks. Estimated-to-expected lung volume was 73% in non-survivors and 102% in survivors (P < 0.05). There were no survivors with a lung volume less than 60% of expected. By logistic regression, mortality could be predicted with a sensitivity of 80%, specificity of 86% and accuracy of 85%. Fetal MR lung volumetrics may be useful for predicting mortality due to respiratory distress in children with early gestational pPROM. (orig.)

    In-utero transfusion is now well under control and improves the survival of foetuses monitored for fetal anemia with a survival rate of more than 80 %. The aim was to evaluate short-term neonatal outcome after fetal severe anemia managed by intrauterine transfusions. We did a retrospective study of all neonates born after management of severe fetal anemia (n = 93) between January 1999 and January 2013 in our regional center. The two main causes of anemia were maternal red blood cell alloimmunization (N = 81, 87 %) and Parvovirus B19 infection (N = 10, 10.8 %). In the alloimmunization group, phototherapy was implemented in 85.2 % of cases with a maximum level of bilirubin of 114.4 ± 60.7 (mg/dl). Transfusion and exchange transfusion were, respectively, required in 51.9 % and in 34.6 % of cases. One neonate presented a convulsive episode, and we observed three neonatal deaths. In the parvovirus group, none of the child had anemia at birth and no management was necessary. Contemporary management of Rhesus disease is associated with encouraging neonatal outcomes. In case of Parvovirus infection, no specific management is necessary at. But, in all cases of fetal anemia, children should be followed up with particular attention to neurologic development. • In-utero transfusion is now well under control and improves the survival of fetuses monitored for fetal anemia. • Limited studies are available on the effect of IUT on postnatal outcome in infants with a history of fetal anemia. What is New: • Contemporary management of severe Rhesus disease is associated with encouraging neonatal outcomes. • The majority of infants can be managed with phototherapy and a limited number of top-up transfusions and exchange transfusions. In case of Parvovirus infection, the short-term neonatal outcome is excellent.

    Expanding the opportunities for for-profit nursing home care is a central theme in the debate on the sustainable organization of the growing nursing home sector in Western countries. We conducted a systematic review of the literature over the last 10 years in order to determine the broad impact of nursing home ownership in the United States. Our review has two main goals: (a) to find out which topics have been studied with regard to financial performance, employee well-being, and client well-being in relation to nursing home ownership and (b) to assess the conclusions related to these topics. The review results in two propositions on the interactions between financial performance, employee well-being, and client well-being as they relate to nursing home ownership. Five search strategies plus inclusion and quality assessment criteria were applied to identify and select eligible studies. As a result, 50 studies were included in the review. Relevant findings were categorized as related to financial performance (profit margins, efficiency), employee well-being (staffing levels, turnover rates, job satisfaction, job benefits), or client well-being (care quality, hospitalization rates, lawsuits/complaints) and then analyzed based on common characteristics. For-profit nursing homes tend to have better financial performance, but worse results with regard to employee well-being and client well-being, compared to not-for-profit sector homes. We argue that the better financial performance of for-profit nursing homes seems to be associated with worse employee and client well-being. For policy makers considering the expansion of the for-profit sector in the nursing home industry, our findings suggest the need for a broad perspective, simultaneously weighing the potential benefits and drawbacks for the organization, its employees, and its clients.

    Elafin is a low molecular weight protein with antileukoproteinase, anti-inflammatory, antibacterial and immunomodulating properties. The profile of Elafin in fetal membranes is not well characterized. This study determined the changes in Elafin expression and concentration in human fetal membrane from patients with preterm prelabor rupture of membranes (PPROM) and in vitro in response to intra-amniotic polymicrobial pathogens. Elafin messenger RNA (mRNA) expressions were studied in fetal membranes from PPROM, normal term as well as in normal term not in labor membranes in an organ explant system treated (24 h) with lipopolysaccharide (LPS), using quantitative reverse transcription-polymerase chain reaction (RT-PCR). Enzyme-linked immunosorbent assay (ELISA) measured Elafin concentrations in culture supernatants from tissues treated with LPS and polybacterial combinations of heat-inactivated Mycoplasma hominis (MH), Ureaplasma urealyticum (UU) and Gardnerella vaginalis (GV). Elafin mRNA expression in fetal membranes from women with PPROM was significantly higher compared to women who delivered at term after normal pregnancy (5.09±3.50 vs. 11.71±2.21; Pmembranes showed a significantly increased Elafin m-RNA expression (Pmembranes also showed no changes in Elafin protein concentrations compared to untreated controls. Higher Elafin expression in PPROM fetal membranes suggests a host response to an inflammatory pathology. However, lack of Elafin response to LPS and polymicrobial treatment is indicative of the minimal anti-inflammatory impact of this molecule in fetal membranes.

  11. Cholesterol synthesis by human fetal hepatocytes: effect of lipoproteins

    The purpose of the present investigation was to determine the effect of various lipoproteins on the rate of cholesterol synthesis of human fetal liver cells maintained in culture. This was accomplished by measuring the rate of incorporation of tritium from tritiated water or carbon 14-labeled acetate into cholesterol in human fetal liver cells. Optimal conditions for each assay were determined. When human fetal liver cells were maintained in the presence of low-density lipoprotein, cholesterol synthesis was inhibited in a concentration-dependent fashion. Intermediate--density lipoprotein and very-low-density lipoprotein also suppressed cholesterol synthesis in human fetal liver cells. In contrast, high-density lipoprotein stimulated cholesterol synthesis in human fetal liver cells. The results of the present as well as our previous investigations suggest that multiple interrelationships exist between fetal liver cholesterol synthesis and lipoprotein-cholesterol utilization by the human fetal adrenal gland and that these processes serve to regulate the lipoprotein-cholesterol levels in fetal plasma

    Although the association between maternal smoking and low birthweight infants has been well established, the mechanisms behind reduced fetal growth are still being elucidated. While many infants are exposed to tobacco smoke in utero, not all are born growth restricted or small for gestational age. Many hypotheses have emerged to explain the differential response to in utero maternal tobacco smoke exposure (MTSE). Studies have shown that both maternal and fetal genotypes may contribute to the discrepant outcomes. However, the contribution of epigenetic changes cannot be ignored. In this review we address two important questions regarding the effect of MTSE on the fetal epigenome. First, does exposure to maternal tobacco smoke in utero alter the fetal epigenome? Secondly, could these alterations be associated with the reduced fetal growth observed with MTSE?

    Although it becomes vitally important only after birth, renal function already plays significant role in maintaining fetal metabolic equilibrium. The kidneys significantly contribute to production of amniotic fluid. Adequate amount of amniotic fluid is needed to stimulate the intrauterine fetal respiratory activity. Intrauterine breathing is essential for lung development. As a result, oligohydramnion is conducive to pulmonary hypoplasia. The latter may lead to neonatal demise soon after birth. In extrauterine life kidneys eliminate nitrogen containing metabolic byproducts. Inadequate renal function results therefore lethal uremia. Integrity of ureters and the urethra is essential for the maintenance of renal function. Retention of urine causes degeneration of the functional units of the kidneys and ensuing deterioration of renal function. Intrauterine kidney puncture or shunt procedure may delay this process in some cases. On the other hand, once renal function has been damaged, no therapy can restart it. Certain anomalies of renal excretory pathways may also be associated with other congenital abnormalities, making the therapeutic efforts pointless. Presence of these associated intrauterine defects makes early pregnancy termination a management alternative, as well as it affects favorably perinatal mortality rates.

    Physical activity (PA) during pregnancy has been shown to be associated with several positive effects for mother, fetus, and offspring. Heart rate variability (HRV) is a noninvasive and surrogate marker to determine fetal overall health and the development of fetal autonomic nervous system. In addition, it has been shown to be significantly influenced by maternal behavior. However, the influence of maternal PA on HRV has not yet been systematically reviewed. Therefore, the aim of this systematic review was to assess the influence of regular maternal PA on maternal, fetal or infant HRV. A systematic literature search following a priori formulated criteria of studies that examined the influence of regular maternal PA (assessed for a minimum period of 6 weeks) on maternal, fetal or infant HRV was performed in the databases Pubmed and SPORTDiscus. Quality of each study was assessed using the standardized Quality Assessment Tool for Quantitative Studies (QATQS). Nine articles were included into the present systematic review: two intervention studies, one prospective longitudinal study, and six post-hoc analysis of subsets of the longitudinal study. Of these articles four referred to maternal HRV, five to fetal HRV, and one to infant HRV. The overall global rating for the standardized quality assessment of the articles was moderate to weak. The articles regarding the influence of maternal PA on maternal HRV indicated contrary results. Five of five articles regarding the influence of maternal PA on fetal HRV showed increases of fetal HRV on most parameters depending on maternal PA. The article referring to infant HRV (measured one month postnatal) showed an increased HRV. Based on the current evidence available, our overall conclusion is that the hypothesis that maternal PA influences maternal HRV cannot be supported, but there is a trend that maternal PA might increase fetal and infant HRV (clinical conclusion). Therefore, we recommend that further, high quality studies

    The finding of fetal ventriculomegaly is variably associated with other fetal abnormalities and, even when isolated, is thought to be linked to abnormal neurodevelopmental outcome. The aim of this study was to undertake a systematic review and meta-analysis of the current literature to assess the prevalence of neurodevelopmental delay in cases of isolated mild fetal ventriculomegaly, as well as the false-negative rate of prenatal imaging for the diagnosis of associated abnormalities in patients referred for isolated mild ventriculomegaly. Studies that assessed neurodevelopmental outcome in isolated ventriculomegaly were identified from a search of scientific databases. Studies that did not check for karyotype or that excluded cases of bilateral ventriculomegaly were not included in the analysis. Ventriculomegaly was defined as mild when the width of the ventricular atrium was between 10 and 15 mm. Cases in which an associated abnormality (abnormal karyotype, structural abnormality or fetal infection) was observed either before or after birth were not considered as part of the isolated group. Neurodevelopmental delay was defined as an abnormal quotient score, according to the test used. The search yielded 961 possible citations; of these, 904 were excluded by review of the title or abstract as they did not meet the selection criteria. Full manuscripts were retrieved for 57 studies, and 20 were included in the review with a total of 699 cases of isolated mild ventriculomegaly. The overall prevalence of neurodevelopmental delay was 7.9% (95% CI, 4.7-11.1%). Of the 20 studies included in the systematic review, nine reported data on postnatal imaging, showing a prevalence of previously undiagnosed findings of 7.4% (95% CI, 3.1-11.8%). The false-negative rate of prenatal imaging is 7.4% in apparently isolated fetal ventriculomegaly of ≤ 15 mm. The incidence of neurodevelopmental delay in truly isolated ventriculomegaly of ≤ 15 mm is 7.9%. As the latter rate is

    A potential role for paracrine secretions in lung organogenesis has been hypothesized (Alescio and Piperno, 1957). These studies present direct support for the paracrine model by demonstrating the presence of locally produced mitogenic/maturational factors in fetal rat lung tissue. Conditioned serum free medium (CSFM) from nineteen-day fetal rat lung cultures was shown to contain several bioactive peptides as detected by 3 H-Thymidine incorporation into chick embryo and rat lung fibroblasts, as well as 14 C-choline incorporation into surfactant in mixed cell cultures. Using ion-exchange chromatography and Sephadex gel filtration, a partially purified mitogen, 11-III, was obtained. The partially purified 11-III stimulates mitosis in chick embryo fibroblasts and post-natal rat lung fibroblasts. Multiplication in fetal rat lung fibroblasts cultures is stimulated only when these are pre-incubated with a competence factor or unprocessed CSFM. This suggests the existence of an endogenously produced competence factor important in the regulation of fetal lung growth. Preparation 11-III does not possess surfactant stimulating activity as assessed by 3 H-choline incorporation into lipids in predominantly type-II cell cultures. These data demonstrate the presence of a maturational/mitogenic factor, influencing type-II mixed cell cultures. In addition, 11-III had been shown to play an autocrine role stimulating the proliferation of fetal lung fibroblasts. Finally, these data suggest the existence of a local produced competence factor

    A specific psychotherapeutic strategy for increasing psychological well-being and resilience, well-being therapy (WBT), has been developed and validated in a number of randomized controlled trials. The findings indicate that flourishing and resilience can be promoted by specific interventions leading to a positive evaluation of one's self, a sense of continued growth and development, the belief that life is purposeful and meaningful, the possession of quality relations with others, the capacity to manage effectively one's life, and a sense of self-determination. The evidence supporting the use of WBT and its specific contribution when it is combined with other psychotherapeutic techniques is still limited. However, the insights gained by the use of WBT may unravel innovative approaches to assessment and treatment of mood and anxiety disorders, to be confirmed by controlled studies, with particular reference to decreasing vulnerability to relapse and modulating psychological well-being and mood. An important characteristic of WBT is self-observation of psychological well-being associated with specific homework. Such perspective is different from interventions that are labeled as positive but are actually distress oriented. Another important feature of WBT is the assumption that imbalances in well-being and distress may vary from one illness to another and from patient to patient. Customary clinical taxonomy and evaluation do not include psychological well-being, which may demarcate major prognostic and therapeutic differences among patients who otherwise seem to be deceptively similar since they share the same diagnosis. © 2017 Wiley Periodicals, Inc.

    To assess whether in a cohort of patients with small for gestational age (SGA) foetuses with estimated fetal weight ≤10 th percentile, maternal hemodynamics, fetal biometry and Dopplers at presentation, can predict the subsequent development of abnormal fetal Dopplers or delivery with birthweight Cheetah), mean arterial pressure, fetal biometry, umbilical artery (UA), middle cerebral artery (MCA) and uterine artery (UT) pulsatility index (PI) and the deepest vertical pool (DVP) of amniotic fluid. Z-scores of these variables were calculated based on reported reference ranges and the values were compared between those with evidence of abnormal fetal Dopplers at presentation (group 1), those that developed abnormal Dopplers in subsequent visits (group 2) and those who did not develop abnormal Dopplers throughout pregnancy (group 3). Abnormal fetal Dopplers were defined as UAPI >95 th percentile, or MCA PI <5 th percentile. Differences in measured variables at presentation were also compared between pregnancies delivering a baby with birthweight <3 rd and ≥3 rd percentile. Multivariate logistic regression analysis was used to determine significant predictors of birthweight <3 rd percentile and evolution from normal fetal Dopplers to abnormal fetal Dopplers in groups 2 and 3. In the study population 14 (16%) cases were in group 1, 19 (22%) in group 2 and 53 (62%) in group 3. The birthweight was <3 rd percentile in 39 (45%) cases and ≥3 rd percentile in 47 (55%). In the study groups, compared to normal populations, there was decreased cardiac output and stroke volume and increased peripheral vascular resistance and mean arterial pressure (MAP) and the deviations from normal were most marked in group 1. Pregnancies with a birthweight <3 rd , compared to those ≥3 rd percentile, had higher deviations from normal in fetal biometry, maternal cardiac output, stroke volume, heart rate and peripheral vascular resistance and UT-PI.

  1. Performance of a wearable acoustic system for fetal movement discrimination.

    Full Text Available Fetal movements (FM are a key factor in clinical management of high-risk pregnancies such as fetal growth restriction. While maternal perception of reduced FM can trigger self-referral to obstetric services, maternal sensation is highly subjective. Objective, reliable monitoring of fetal movement patterns outside clinical environs is not currently possible. A wearable and non-transmitting system capable of sensing fetal movements over extended periods of time would be extremely valuable, not only for monitoring individual fetal health, but also for establishing normal levels of movement in the population at large. Wearable monitors based on accelerometers have previously been proposed as a means of tracking FM, but such systems have difficulty separating maternal and fetal activity and have not matured to the level of clinical use. We introduce a new wearable system based on a novel combination of accelerometers and bespoke acoustic sensors as well as an advanced signal processing architecture to identify and discriminate between types of fetal movements. We validate the system with concurrent ultrasound tests on a cohort of 44 pregnant women and demonstrate that the garment is capable of both detecting and discriminating the vigorous, whole-body 'startle' movements of a fetus. These results demonstrate the promise of multimodal sensing for the development of a low-cost, non-transmitting wearable monitor for fetal movements.

    Providing well-being and maintaining good health are main objectives subjects seek from diet. This manuscript describes the development and preliminary validation of an instrument assessing well-being associated with food and eating habits in a general healthy population. Qualitative data from 12 groups of discussion (102 subjects) conducted with healthy subjects were used to develop the core of the Well-being related to Food Questionnaire (Well-BFQ). Twelve other groups of discussion with subjects with joint (n = 34), digestive (n = 32) or repetitive infection complaints (n = 30) were performed to develop items specific to these complaints. Five main themes emerged from the discussions and formed the modular backbone of the questionnaire: "Grocery shopping", "Cooking", "Dining places", "Commensality", "Eating and drinking". Each module has a common structure: items about subject's food behavior and items about immediate and short-term benefits. An additional theme - "Eating habits and health" - assesses subjects' beliefs about expected benefits of food and eating habits on health, disease prevention and protection, and quality of ageing. A preliminary validation was conducted with 444 subjects with balanced diet; non-balanced diet; and standard diet. The structure of the questionnaire was further determined using principal component analyses exploratory factor analyses, with confirmation of the sub-sections food behaviors, immediate benefits (pleasure, security, relaxation), direct short-term benefits (digestion and satiety, energy and psychology), and deferred long-term benefits (eating habits and health). Thirty-three subscales and 14 single items were further defined. Confirmatory analyses confirmed the structure, with overall moderate to excellent convergent and divergent validity and internal consistency reliability. The Well-BFQ is a unique, modular tool that comprehensively assesses the full picture of well-being related to food and eating habits in

    Parvovirus B19 infection causes 5% to 15% of cases of nonimmune hydrops fetalis. The aim of our study was to evaluate the use of immunohistochemistry in diagnosing parvovirus infection in fetal and placental tissue during routine fetal and perinatal autopsies. Histology slides of 20 cases of confirmed parvovirus infection were reviewed, and immunohistochemistry was applied to selected blocks of fetal and placental tissue. Immunohistochemistry was positive in all 20 cases, and histologic viral inclusions were seen in 19 cases. Immunohistochemical staining was closely correlated with histology and was more sensitive than histology in detecting virally infected cells, especially in autolyzed tissue. All cases also had confirmatory evidence of parvovirus infection by polymerase chain reaction of fetal liver and positive maternal serology, where it was available. We conclude that parvovirus immunohistochemistry is a reliable method for diagnosing parvovirus infection, especially in autolyzed tissue where histologic assessment may be suboptimal.

    Full Text Available The rapid changes that have taken place in recent years in relation to techniques used to image the fetal heart have emphasized the need to have a detailed knowledge ofnormal cardiac anatomy. Without such knowledge, it is difficult, if not impossible, to recognize the multiple facets of congenital cardiac disease. From the inception of fetal echocardiographic screening, the importance of basic knowledge of cardiac anatomy has been well recognized. The current machines used for imaging, however, now make it possible potentially to recognize features not appreciated at the start of the specialty. So as to match the advances made in imaging, we have now revisited our understanding of normal cardiac anatomy in the mid-gestational fetus. This was made possible by our dissection of 10 fetal hearts, followed by production of addition histological sections that mimic the standard ultrasound views. The fetuses ranged in gestational age from between 20 and 28 weeks. We then correlated the obtained anatomic images with the corresponding ultrasonic images used in the standard fetal screening scan. We also interrogated the anatomic sections so as to clarify ongoing controversies regarding detailed features of the normal cardiac anatomy. We have been able to show that the views now obtained using current technology reveal many details of anatomy not always appreciated at earlier times. Knowledge of these features should now permit diagnosis of most congenital cardiac malformations. The anatomic-echocardiographic correlations additionally provide a valuable resource for both the understanding and teaching of fetal echocardiography.

    The objective of this study is to assess the outcomes and risk factors of fetal bradycardia after external cephalic version (ECV). We performed a retrospective study of women who underwent ECV after 35 weeks of gestation in 2010-2016. We assessed the birth outcomes, including umbilical cord artery pH, according to the duration of fetal bradycardia and the risk factors for bradycardia. Among 390 cases, 189 (48.5%) cases showed fetal bradycardia during or immediately after ECV. The duration of fetal bradycardia was 10 min occurred in three cases; emergency cesarean section was performed in each case, with delivery after 12-4 min of bradycardia. Two of three cases showed low Apgar scores at 5 min, with an umbilical cord arterial pH of 10 min after ECV was a risk factor for asphyxia. Thus, delivery should be completed within 10 min after bradycardia. A low maternal BMI and a prolonged ECV procedure were risk factors for bradycardia after ECV.

    To establish the standard guideline for differentiating the extrarenal pelvis from obstructive uropathy on fetal ultrasonogram (US) to avoid unnecessary postnatal follow-up and other additional examinations. From July 2000 to July 2001, Thirty-four kidneys with hydronephrosis diagnosed on fetal ultrasonogram performed during the third trimester of pregnancy were included in this study. Hydronephrosis was defined as the pelvic anteroposterior (AP) diameter being 4 mm or greater before 33 weeks of gestation while 7 mm or greater at or after 33 weeks of gestation. The size of the renal pelvis was measured at intrarenal, intra-extrarenal junctional and extrarenal portions in every kidney on the transverse view of the fetal renal hiluin. Postnatally, all neonates underwent renal ultrasonogram 2 to 8 days after birth, and renal pelvic diameters were measured using the same method as the fetal US in 28 kidneys. We then compared the extrarenal-intrarenal ratio (E/I ratio) of pelvic diameter between fetal and neoatal kidneys. We presumed that the extrarenal pelvis in fetal US was the pelvis showing the normal intrarenal pelvic diameter accompanied by the most dilated exrtarenal pelvic diameter. Follow-up ultrasonograms were measured using the same method as the fetal US in 28 kidneys. We then compared the extrarenal intrarenal ratio (E/I ratio) of pelvic diameter between fetal and neonatal kidneys. We presumed that the extrarenal pelvis on fetal US was the pelvis showing the normal intrarenal pelvic diameter accompanied by the most dilated extrarenal pelvic diameter. Follow-up ultrasonograms were performed in 12 of 17 neonates who had the maximal diameter at extrarenal portion on fetal ultrasonogram. VCUG and IVU were taken in 2 patients with a persistent dilatation of the renal pelvis on follow-up ultrasonograms. On fetal US, 17/34 kidneys showed the extrarenal portion with the most dilatation while in 12/34 kidneys, the intra-extra renal junction portion was the most

    Fetal MRI can be performed in the second and third trimesters. During this time, the fetal brain undergoes profound structural changes. Interpretation of appropriate development might require comparison with normal age-based models. Consultation of a hard-copy atlas is limited by the inability to compare multiple ages simultaneously. To provide images of normal fetal brains from weeks 18 through 37 in a digital format that can be reviewed interactively. This will facilitate recognition of abnormal brain development. T2-W images for the atlas were obtained from fetal MR studies of normal brains scanned for other indications from 2005 to 2007. Images were oriented in standard axial, coronal and sagittal projections, with laterality established by situs. Gestational age was determined by last menstrual period, earliest US measurements and sonogram performed on the same day as the MR. The software program used for viewing the atlas, written in C#, permits linked scrolling and resizing the images. Simultaneous comparison of varying gestational ages is permissible. Fetal brain images across gestational ages 18 to 37 weeks are provided as an interactive digital atlas and are available for free download from http://radiology.seattlechildrens.org/teaching/fetal_brain . Improved interpretation of fetal brain abnormalities can be facilitated by the use of digital atlas cataloging of the normal changes throughout fetal development. Here we provide a description of the atlas and a discussion of normal fetal brain development.

    Fetal growth restriction (FGR) is defined as the inability of a fetus to achieve its genetic growth potential and is associated with a significantly increased risk of morbidity and mortality. Clinically, FGR is diagnosed as a fetus falling below the 5th centile of customised growth charts. Sildenafil citrate (SC, Viagra™), a potent and selective phosphodiesterase-5 inhibitor, corrects ex vivo placental vascular dysfunction in FGR, demonstrating potential as a therapy for this condition. However, many FGR cases present without an abnormal vascular phenotype, as assessed by Doppler measures of uterine/umbilical artery blood flow velocity. Thus, we hypothesized that SC would not increase fetal growth in a mouse model of FGR, the placental-specific Igf2 knockout mouse, which has altered placental exchange capacity but normal placental blood flow. Fetal weights were increased (by 8%) in P0 mice following maternal SC treatment (0.4 mg/ml) via drinking water. There was also a trend towards increased placental weight in treated P0 mice (P = 0.056). Additionally, 75% of the P0 fetal weights were below the 5th centile, the criterion used to define human FGR, of the non-treated WT fetal weights; this was reduced to 51% when dams were treated with SC. Umbilical artery and vein blood flow velocity measures confirmed the lack of an abnormal vascular phenotype in the P0 mouse; and were unaffected by SC treatment. 14C-methylaminoisobutyric acid transfer (measured to assess effects on placental nutrient transporter activity) per g placenta was unaffected by SC, versus untreated, though total transfer was increased, commensurate with the trend towards larger placentas in this group. These data suggest that SC may improve fetal growth even in the absence of an abnormal placental blood flow, potentially affording use in multiple sub-populations of individuals presenting with FGR.

    Insulin-like growth factor-I (IGF-I) and non-esterified fatty acids (NEFA) play an essential role in fetal growth and development. To date, fetal fluids IGF-I and NEFA levels at term canine pregnancy are unknown and could be related to the neonatal development and breed size. For these reasons, the aims of the present study were as follows: (1) to evaluate IGF-I and NEFA concentrations in fetal fluids collected from normally developed and viable newborn puppies born at term of normal pregnancies; (2) to assess possible differences between IGF-I and NEFA levels in amniotic compared with allantoic fluid; (3) to detect possible relationship between breed body size and IGF-I and NEFA amniotic and allantoic concentrations; (4) to evaluate possible differences in IGF-I fetal fluids levels between male and female puppies; and (5) to assess possible correlations between the two hormones in each type of fluid. The study enrolled 25 pure breed bitches submitted to elective Cesarean section at term because of the high risk of dystocia or previous troubles at parturition. At surgery, amniotic and allantoic fluids were collected and assayed for IGF-I and NEFA. IGF-I and NEFA amounts in both amniotic and allantoic fluids of different breed size bitches (small: ≤10 kg; medium: 11-25 kg; large: 26-40 kg) were detected, as well as the effect of gender on IGF-I levels. On a total of 73 amniotic and 76 allantoic samples collected by normal, viable, and mature newborns, the mean IGF-I concentration was significantly higher in amniotic than in allantoic fluid in all three groups, but the amniotic IGF-I levels were significantly lower in small and medium size bitches when compared with large ones. No significant differences were found in allantoic IGF-I concentrations among size groups. A significant effect of the puppy gender on IGF-I content in both fetal fluids was not reported. Regarding NEFA, in all the three groups, the mean NEFA concentration did not significantly differ

    To define the normal T2* values of liver in the third trimester of pregnancy in normal fetuses. Multi-echo gradient echo T2* sequence was applied to the fetal abdomen in the axial plane in women undergoing a fetal MRI (1.5 Tesla [T], MRI system). A region of interest, best visualizing in the liver parenchyma was used for measurements. Studies were independently read by two experienced readers to assess intra- and interobserver variability. The study cohort included 46 pregnant women undergoing fetal MRI for any indication other than liver pathology evaluation. Three scans were excluded due to fetal motion. Average maternal and gestational age were 33 ± 4 years and 31.9 ± 3 weeks, respectively. Average T2* values were found to be 19.7 ± 7.4 ms. The intra- and interobserver agreement were very good: 0.93 and 0.8-0.084, respectively. T2* MRI allows noninvasive evaluation liver iron content in the third trimester fetus. Measured values at this stage of pregnancy are significantly lower compared with values cited in the literature for adults. This is of major importance in the correct diagnosis of fetal iron overload states. We propose this as the standard reference when evaluating fetal iron overload pathology.

    The purpose of fetal magnetoencephalography (fMEG) is to record and analyze fetal brain activity. Unavoidably, these recordings consist of a complex mixture of bio-magnetic signals from both mother and fetus. The acquired data include biological signals that are related to maternal and fetal heart function as well as fetal gross body and breathing movements. Since fetal breathing generates a significant source of bio-magnetic interference during these recordings, the goal of this study was to identify and quantify the signatures pertaining to fetal breathing movements (FBM). The fMEG signals were captured using superconducting quantum interference devices (SQUIDs) The existence of FBM was verified and recorded concurrently by an ultrasound-based video technique. This simultaneous recording is challenging since SQUIDs are extremely sensitive to magnetic signals and highly susceptible to interference from electronic equipment. For each recording, an ultrasound-FBM (UFBM) signal was extracted by tracing the displacement of the boundary defined by the fetal thorax frame by frame. The start of each FBM was identified by using the peak points of the UFBM signal. The bio-magnetic signals associated with FBM were obtained by averaging the bio-magnetic signals time locked to the FBMs. The results showed the existence of a distinctive sinusoidal signal pattern of FBM in fMEG data

    A well-organized interplay between many molecular factors as well as mechanical forces influence fetal lung development. At the end of this complex process a sufficiently sized and structurally mature organ should ensure the postnatal survival of the newborn. Besides prenatal ultrasonography, magnetic resonance imaging (MRI) can now be used to investigate normal and pathological human lung growth in utero. Oligohydramnios, due to premature rupture of membranes (PROM), is an important risk factor for compromised fetal lung growth. In these situations MR volumetry can be used to measure the size of the fetal lung quite accurately. Together with the evaluation of lung signal intensities on T2-weighted sequences, fetuses with pulmonary hypoplasia can be readily detected. (orig.) [German] Die fetale Lungenentwicklung wird einerseits durch eine Vielzahl molekularer Faktoren und andererseits durch mechanisch-physiologische Kraefte beeinflusst. Ein geordnetes Zusammenspiel dieser Mechanismen fuehrt zu einem ausreichend grossen und strukturell reifen Organ, das sofort nach der Geburt das Ueberleben des Neugeborenen sicherstellt. Neben der praenatalen Ultraschalluntersuchung bietet nun auch die Magnetresonanztomographie (MRT) die Moeglichkeit, die normale und pathologische fetale Lungenentwicklung zu untersuchen. Ein wesentlicher Risikofaktor fuer eine Beeintraechtigung der Lungenentwicklung ist die verminderte Fruchtwassermenge nach vorzeitigem Blasensprung. In diesen Faellen kann die MR-Volumetrie dazu eingesetzt werden, die Groesse der fetalen Lungen relativ genau zu bestimmen. Gemeinsam mit der Beurteilung der MR-Signalintensitaeten des Lungengewebes auf T2-gewichteten Sequenzen koennen Feten mit hypoplastischen Lungen mit zunehmender Sicherheit bereits praenatal identifiziert werden.

    Full Text Available Great expectations are connected with application of indirect fetal electrocardiography (FECG, especially for home telemonitoring of pregnancy. Evaluation of fetal heart rate (FHR variability, when determined from FECG, uses the same criteria as for FHR signal acquired classically—through ultrasound Doppler method (US. Therefore, the equivalence of those two methods has to be confirmed, both in terms of recognizing classical FHR patterns: baseline, accelerations/decelerations (A/D, long-term variability (LTV, as well as evaluating the FHR variability with beat-to-beat accuracy—short-term variability (STV. The research material consisted of recordings collected from 60 patients in physiological and complicated pregnancy. The FHR signals of at least 30 min duration were acquired dually, using two systems for fetal and maternal monitoring, based on US and FECG methods. Recordings were retrospectively divided into normal (41 and abnormal (19 fetal outcome. The complex process of data synchronization and validation was performed. Obtained low level of the signal loss (4.5% for US and 1.8% for FECG method enabled to perform both direct comparison of FHR signals, as well as indirect one—by using clinically relevant parameters. Direct comparison showed that there is no measurement bias between the acquisition methods, whereas the mean absolute difference, important for both visual and computer-aided signal analysis, was equal to 1.2 bpm. Such low differences do not affect the visual assessment of the FHR signal. However, in the indirect comparison the inconsistencies of several percent were noted. This mainly affects the acceleration (7.8% and particularly deceleration (54% patterns. In the signals acquired using the electrocardiography the obtained STV and LTV indices have shown significant overestimation by 10 and 50% respectively. It also turned out, that ability of clinical parameters to distinguish between normal and abnormal groups do not

This prospective observational study was conducted in the Obstetrics department of Ad-din Women Medical College Hospital during the period of June, 2009 to July, 2010. A total of 14,015 pregnant patients were admitted in the study place after the age of viability, which was taken as 28 weeks of gestation for our facilities. Eighty-three (0.59%) of them were identified as intrauterine fetal death. Assessment of maternal sociodemographic characteristics and maternal-fetal risk factors were evaluated with a semi structured questionnaire pretested. Majority (81.92%, n=68) of the patients were below 30 years of age, 78.31% belonged to middle socioeconomic group. Almost 58% women had education below SSC level and 28.91% took regular antenatal checkup. About 61.45% patients were multigravida. Most (59.04%) ante-partum deaths were identified below 32 weeks of pregnancy. Out of 83 patients, maternal risk factors were identified in 41(49.59%) cases where fetal risk factors were found in 16(19.27%) cases; no risk factors could be determined in rests. Hypertension (48.78%), diabetes (21.95%), hyperpyrexia (17.3%), abruptio placentae (4.88%) and UTI (7.36%) were identified as maternal factors; and congenital anomaly (37.5%), Rh incompatibility (37.5%), multiple pregnancy (12.5%) and post-maturity (12.5%) were the fetal risk factors. Here, proximal biological risk factors are most important in ante-partum fetal deaths. More investigations and facilities are needed to explain the causes of antepartum deaths.

    This study evaluated 1-year linear trajectories of patient-reported dimensions of quality of life among patients receiving dialysis. Longitudinal observational study. 227 patients recruited from 12 dialysis centers. Sociodemographic and clinical characteristics. Participants completed an hour-long interview monthly for 12 months. Each interview included patient-reported outcome measures of overall symptoms (Edmonton Symptom Assessment System), physical functioning (Activities of Daily Living/Instrumental Activities of Daily Living), cognitive functioning (Patient's Assessment of Own Functioning Inventory), emotional well-being (Center for Epidemiologic Studies Depression Scale, State Anxiety Inventory, and Positive and Negative Affect Schedule), and spiritual well-being (Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being Scale). For each dimension, linear and generalized linear mixed-effects models were used. Linear trajectories of the 5 dimensions were jointly modeled as a multivariate outcome over time. Although dimension scores fluctuated greatly from month to month, overall symptoms, cognitive functioning, emotional well-being, and spiritual well-being improved over time. Older compared with younger participants reported higher scores across all dimensions (all Pspiritual well-being compared with their white counterparts (P<0.01). Clustering analysis of dimension scores revealed 2 distinctive clusters. Cluster 1 was characterized by better scores than those of cluster 2 in nearly all dimensions at baseline and by gradual improvement over time. Study was conducted in a single region of the United States and included mostly patients with high levels of function across the dimensions of quality of life studied. Multidimensional patient-reported quality of life varies widely from month to month regardless of whether overall trajectories improve or worsen over time. Additional research is needed to identify the best approaches to incorporate

    A well-organized interplay between many molecular factors as well as mechanical forces influence fetal lung development. At the end of this complex process a sufficiently sized and structurally mature organ should ensure the postnatal survival of the newborn. Besides prenatal ultrasonography, magnetic resonance imaging (MRI) can now be used to investigate normal and pathological human lung growth in utero. Oligohydramnios, due to premature rupture of membranes (PROM), is an important risk factor for compromised fetal lung growth. In these situations MR volumetry can be used to measure the size of the fetal lung quite accurately. Together with the evaluation of lung signal intensities on T2-weighted sequences, fetuses with pulmonary hypoplasia can be readily detected. (orig.) [de

  1. Obesity and Lifespan Health—Importance of the Fetal Environment

    2014-04-01

    Full Text Available A marked increase in the frequency of obesity at the population level has resulted in an increasing number of obese women entering pregnancy. The increasing realization of the importance of the fetal environment in relation to chronic disease across the lifespan has focused attention on the role of maternal obesity in fetal development. Previous studies have demonstrated that obesity during adolescence and adulthood can be traced back to fetal and early childhood exposures. This review focuses on factors that contribute to early developmental events, such as epigenetic modifications, the potential for an increase in inflammatory burden, early developmental programming changes such as the variable development of white versus brown adipose tissue, and alterations in organ ontogeny. We hypothesize that these mechanisms promote an unfavorable fetal environment and can have a long-standing impact, with early manifestations of chronic disease that can result in an increased demand for future health care. In order to identify appropriate preventive measures, attention needs to be placed both on reducing maternal obesity as well as understanding the molecular, cellular, and epigenetic mechanisms that may be responsible for the prenatal onset of chronic disease.

    The development of ultrafast sequences has led to a significant improvement in fetal MRI. Imaging protocols have to be adjusted to the rapidly developing fetal central nervous system (CNS) and to the clinical question. Sequence parameters must be changed to cope with the respective developmental stage, to produce images free from motion artefacts and to provide optimum visualization of the region and focus of interest. In contrast to postnatal studies, every suspect fetal CNS abnormality requires examination of the whole fetus and the extrafetal intrauterine structures including the uterus. This approach covers both aspects of fetal CNS disorders: isolated and complex malformations and cerebral lesions arising from the impaired integrity of the feto-placental unit. (orig.)

    Fetal MR imaging often poses a diagnostic challenge for the radiologist. Both fetal anatomy and pathology differ decidedly from pediatric and adult MR imaging. While ultrasound remains the method of choice for screening examinations of the fetus, MR imaging is playing an increasingly important role in the detection and classification of malformations not diagnosable by ultrasonography alone. Recently, advances in fast single-shot MR sequences have allowed high-resolution, high-quality imaging of the moving fetus. Preferable sequences to be applied are a true fast imaging steady precession (true-FISP) or a half-Fourier acquired single-shot turbo spin-echo (HASTE) sequence. Premedication is generally no longer required. In all fetal MR imaging, every aspect of fetal anatomy has to be scrutinized. Subsequently, any abnormalities need to be described and classified. A close collaboration with the referring obstetrician is of paramount importance. (orig.)

    Purpose: To investigate the potential of fMRI to measure changes in fetal tissue oxygenation during acute maternal hypoxia in fetal lambs. Material and Methods: Two ewes carrying singleton fetuses (gestational age 125 and 131 days) underwent MR imaging under inhalation anesthesia. BOLD imaging of the fetal brain, liver and myocardium was performed during acute maternal hypoxia (oxygen replaced by N 2 O). Maternal oxygen saturation and heart rate were monitored by a pulse-oxymeter attached to the maternal tongue. Results: Changes of fetal tissue oxygenation during maternal hypoxia were clearly visible with BOLD MRI. Signal intensity decreases were more distinct in liver and heart (∝40%) from control than in the fetal brain (∝10%). Conclusions: fMRI is a promising diagnostic tool to determine fetal tissue oxygenation and may open new opportunities in monitoring fetal well being in high risk pregnancies complicated by uteroplacentar insufficiency. Different signal changes in liver/heart and brain may reflect a centralization of the fetal blood flow. (orig.) [de

    Fetal MRI can be performed in the second and third trimesters. During this time, the fetal brain undergoes profound structural changes. Interpretation of appropriate development might require comparison with normal age-based models. Consultation of a hard-copy atlas is limited by the inability to compare multiple ages simultaneously. To provide images of normal fetal brains from weeks 18 through 37 in a digital format that can be reviewed interactively. This will facilitate recognition of abnormal brain development. T2-W images for the atlas were obtained from fetal MR studies of normal brains scanned for other indications from 2005 to 2007. Images were oriented in standard axial, coronal and sagittal projections, with laterality established by situs. Gestational age was determined by last menstrual period, earliest US measurements and sonogram performed on the same day as the MR. The software program used for viewing the atlas, written in C, permits linked scrolling and resizing the images. Simultaneous comparison of varying gestational ages is permissible. Fetal brain images across gestational ages 18 to 37 weeks are provided as an interactive digital atlas and are available for free download. Improved interpretation of fetal brain abnormalities can be facilitated by the use of digital atlas cataloging of the normal changes throughout fetal development.

Fetal MRI is an interactive scanning of the moving fetus owed to the use of fast sequences. Single-shot fast spin-echo (SSFSE T2-weighted imaging is a standard sequence. T1-weighted sequences are primarily used to demonstrate fat, calcification and hemorrhage. Balanced steady-state free-precession (SSFP, are beneficial in demonstrating fetal structures as the heart and vessels. Diffusion weighted imaging (DWI, MR spectroscopy (MRS, and diffusion tensor imaging (DTI have potential applications in fetal imaging. Knowing the developing fetal MR anatomy is essential to detect abnormalities. MR evaluation of the developing fetal brain should include recognition of the multilayered-appearance of the cerebral parenchyma, knowledge of the timing of sulci appearance, myelination and changes in ventricular size. With advanced gestation, fetal organs as lungs and kidneys show significant changes in volume and T2-signal. Through a systematic approach, the normal anatomy of the developing fetus is shown to contrast with a wide spectrum of fetal disorders. The abnormalities displayed are graded in severity from simple common lesions to more complex rare cases. Complete fetal MRI is fulfilled by careful evaluation of the placenta, umbilical cord and amniotic cavity. Accurate interpretation of fetal MRI can provide valuable information that helps prenatal counseling, facilitate management decisions, guide therapy, and support research studies.

    A fundamental question addressed in this study was the feasibility of preterm birth prediction based on a noncontact investigation of fetal membranes in situ. Although the phenomena of preterm birth and the premature rupture of the fetal membrane are well known, currently, there are no diagnostic tools for their prediction. The aim of this study was to assess whether optical coherence tomography could be used for clinical investigations of high-risk pregnancies. The thickness of fetal membranes was measured in parallel by optical coherence tomography and histological techniques for the following types of birth: normal births, preterm births without premature ruptures and births at full term with premature rupture of membrane. Our study revealed that the membrane thickness correlates with the birth type. Normal births membranes were statistically significantly thicker than those belonging to the other two groups. Thus, in spite of almost equal duration of gestation of the normal births and the births at full term with premature rupture, the corresponding membrane thicknesses differed. This difference is possibly related to previously reported water accumulation in the membranes. The optical coherence tomography results were encouraging, suggesting that this technology could be used in future to predict and distinguish between different kinds of births.

  10. Fetal Primary Cardiac Tumors During Perinatal Period

    Full Text Available Fetal primary cardiac tumors are rare, but they may cause complications, which are sometimes life threatening, including arrhythmias, hydrops fetalis, ventricular outflow/inflow obstruction, cardiac failure, and even sudden death. Among fetal primary cardiac tumors, rhabdomyomas are most common, followed by teratomas, fibromas, hemangiomas, and myxomas. Everolimus, a mammalian target of rapamycin inhibitor, has been reported to be an effective drug to cause tumor remission in three neonates with multiple cardiac rhabdomyomas. Neonatal cardiac surgery for the resection of primary cardiac tumors found by fetal echocardiography has been reported sporadically. However, open fetal surgery for pericardial teratoma resection, which was performed successfully via a fetal median sternotomy in one case report, could be a promising intervention to rescue these patients with large pericardial effusions. These recent achievements undoubtedly encourage further development in early management of fetal cardiac tumors. Owing to the rarity of fetal primary cardiac tumors, relevant information in terms of prenatal diagnosis, treatment, and prognosis remains to be clarified.

    2014-01-01

    Long-term adaptive changes occurring in a developing fetus in response to unstable in utero environmental conditions, which appear at a particular time (critical window), are called intrauterine or fetal programming. These adaptive changes are beneficial during the intrauterine period because they adapt the fetus to current needs, but may turn out to be harmful in the end and lead to development of chronic diseases in adult life. Fetal programming means the structural and functional changing of an organism, metabolism and function of some cells, tissues and systems, that occur even despite intrauterine limitations. Events of fetal life influence the determination of physiological patterns which may manifest as disease processes in the adulthood (Barker's hypothesis). Genetic and environmental factors (poor diet in pregnancy chronic intrauterine fetal hypoxia, the effects of xenobiotics and drugs, as well as hormonal disorders) influence the phenotype of a newborn and are involved in the intrauterine programming process. The effects of fetal programming may be passed along to the next generations via not fully understood pathways, which probably include epigenetic mechanisms. Most of the mechanisms underlying this process remain unclear and need to be elucidated.

    O 6 -Methylguanine methyltransferase (O 6 -MT) was measured and compared in extracts of 7 human fetal tissues obtained from 21 different fetal specimens as a function of fetal age and race, and maternal smoking and drug usage. Activity was determined from the proteinase-K solubilized radioactivity transferred from the DNA to the O 6 -MT. S9 homogenates were incubated with a heat depurinated [ 3 H]-methylnitrosourea alkylated DNA. Liver exhibited the highest activity followed by kidney, lung, small intestine, large intestine, skin and brain. Each of the tissues exhibited a 3- to 5-fold level of interindividual variation of O 6 -MT. There did not appear to be any significant difference of O 6 -MT in the tissues obtained from mothers who smoked cigarettes during pregnancy. Also, fetal race and age did not appear to account for the level of variation of O 6 -MT. The fetal tissues obtained from an individual using phenobarbital and smoking exhibited 4-fold increases in O 6 -MT activity. The tissues obtained from another individual on kidney dialysis were 2- to 3-fold higher than the normal population. These data suggest that the variation in human O 6 -MT can not be explained by racial or smoking factors, but may be modulated by certain drugs

     Although Ureaplasma species are the most common organisms associated with prematurity, their effects on the maternal and fetal immune system remain poorly characterized.  Rhesus macaque dams at approximately 80% gestation were injected intra-amniotically with 10 7 colony-forming units of Ureaplasma parvum or saline (control). Fetuses were delivered surgically 3 or 7 days later. We performed comprehensive assessments of inflammation and immune effects in multiple fetal and maternal tissues.  Although U. parvum grew well in amniotic fluid, there was minimal chorioamnionitis. U. parvum colonized the fetal lung, but fetal systemic microbial invasion was limited. Fetal lung inflammation was mild, with elevations in CXCL8, tumor necrosis factor (TNF) α, and CCL2 levels in alveolar washes at day 7. Inflammation was not detected in the fetal brain. Significantly, U. parvum decreased regulatory T cells (Tregs) and activated interferon γ production in these Tregs in the fetus. It was detected in uterine tissue by day 7 and induced mild inflammation and increased expression of connexin 43, a gap junction protein involved with labor.  U. parvum colonized the amniotic fluid and caused uterine inflammation, but without overt chorioamnionitis. It caused mild fetal lung inflammation but had a more profound effect on the fetal immune system, decreasing Tregs and polarizing them toward a T-helper 1 phenotype. © The Author 2016.

    Exposure to the ubiquitous environmental pollutant benzene is positively correlated with leukemia in adults and may be associated with childhood leukemia following in utero exposure. While numerous studies implicate oxidative stress and DNA damage as playing a role in benzene-mediated carcinogenicity, emerging evidence suggests that alterations in epigenetic regulations may be involved. The present study aimed to determine whether DNA methylation and/or various histone modifications were altered following in utero benzene exposure in CD-1 mice. Global DNA methylation and promoter-specific methylation of the tumor suppressor gene, p15, were assessed. Additionally, levels of acetylated histones H3, H4, and H3K56, as well as methylated histones H3K9 and H3K27 were assessed by Western blotting. A significant decrease in global DNA methylation of maternal bone marrow was observed following benzene exposure; however no effect on global DNA methylation was detected in fetal livers. Additionally, no effect of benzene exposure was observed on p15 promoter methylation or any measured histone modifications in both maternal bone marrow and fetal livers. These results suggest that the methodology used in the present study did not reveal alterations in DNA methylation and histone modifications following in utero exposure to benzene; however further experimentation investigating these modifications at the whole genome/epigenome level, as well as at later stages of benzene-induced carcinogenesis, are warranted. - Highlights: • Benzene exposure in pregnant mice decreased global DNA methylation in maternal bone marrow. • Benzene exposure in pregnant mice had no effect on global DNA methylation in fetal livers. • No effect of benzene exposure was observed on p15 promoter methylation. • No effect of benzene on measured histone modifications in both maternal bone marrow and fetal livers was observed.

    Fetal intolerance of labor is a common indication for delivery by Caesarean section. Diagnosis is based on the presence of category III fetal heart rate tracing, which is an abnormal heart tracing associated with increased likelihood of fetal hypoxia and metabolic acidemia. This study analyzed data from 177 unique women who, during their prenatal visits (7-15 weeks and/or 24-32 weeks) to Atlanta area prenatal care clinics, consented to provide blood samples for DNA methylation (HumanMethylation450 BeadChip) and gene expression (Human HT-12 v4 Expression BeadChip) analyses. We focused on 57 women aged 18-36 (mean 25.4), who had DNA methylation data available from their second prenatal visit. DNA methylation patterns at CpG sites across the genome were interrogated for associations with fetal intolerance of labor. Four CpG sites (P value intolerance of labor. DNA methylation and gene expression were negatively associated when examined longitudinally during pregnancy using a linear mixed-effects model. Positive predictive values of methylation of these four sites ranged from 0.80 to 0.89, while negative predictive values ranged from 0.91 to 0.92. The four CpG sites were also associated with fetal intolerance of labor in an independent cohort (the Johns Hopkins Prospective PPD cohort). Therefore, fetal intolerance of labor could be accurately predicted from maternal blood samples obtained between 24-32 weeks gestation. Fetal intolerance of labor may be accurately predicted from maternal blood samples obtained between 24-32 weeks gestation by assessing DNA methylation patterns of SLC9B1. The identification of pregnant women at elevated risk for fetal intolerance of labor may allow for the development of targeted treatments or management plans.

    Full Text Available Past research has revealed that relative importance a person places on extrinsic life goals as oposed to intrinsic ones is related to lower well-being. But sometimes it is more important why a goal is being pursued than the content of the goal. Materialistic aspirations will not decrease people's well-being if they help them to achieve basic financial security or some intrinsic goals. On the other hand, if social comparison or seeking power drives extrinsic orientation, these aspirations may be detrimental for well-being, since they do not satisfy satisfy our basic psychological needs. Research from Croatia and other, less rich countries suggest that extrinsic aspirations are not necessarily deterimental but may even contribute to well-being. This finding suggests that various factors can moderate the relationship between aspirations and well-being. Intrinsic life goals may probably be affordable only for people who are well off enough. The meaning of financial success in transitional and poor countries may not necesseraly be associated with purchase and consumption. On the contrary, it may bring opportunities and possibilities of self-expression and self-growth. Individualistic societies allow individuals to pursue their intrinsic goals while collectivistic cultures stress extrinsic ones. Although this extrinsic orientation may detract their well-being, the sense of individual well-being may not be as important to them as the survival of the group they belong to or so called social well-being.

    The radiopharmaceutical administration with diagnostic or therapeutic purpose during pregnancy implies a prenatal radiation dose. The dose assessment and the evaluation of the radiological risks become relevant due to the great radiosensitivity of the fetal tissues in development. This paper is a revision of the available data for estimating fetal doses in the cases of the more frequently used radiopharmaceuticals in nuclear medicine, taking into account recent investigation in placental crossover. The more frequent diagnostic and therapeutic procedures were analyzed according to the radiation doses implied. (author)

    The role of MRI in the evaluation of fetal abnormalities is still under evaluation. We describe a case of an intracranial mass that was initially identified by prenatal ultrasound and was further evaluated by MRI. Ultimately, the findings were most consistent with hematoma secondary to an underlying dural malformation with spontaneous involution. The advantages of fetal MRI in the assessment and management of this abnormality will be discussed. (orig.)

    The human fetus is able to mount a systemic inflammatory response when exposed to microorganisms. This stereotypic response has been termed the 'fetal inflammatory response syndrome' (FIRS), defined as an elevation of fetal plasma interleukin-6 (IL-6). FIRS is frequently observed in patients whose preterm deliveries are associated with intra-amniotic infection, acute inflammatory lesions of the placenta, and a high rate of neonatal morbidity. Recently, a novel form of fetal systemic inflammation, characterized by an elevation of fetal plasma CXCL10, has been identified in patients with placental lesions consistent with 'maternal anti-fetal rejection'. These lesions include chronic chorioamnionitis, plasma cell deciduitis, and villitis of unknown etiology. In addition, positivity for human leukocyte antigen (HLA) panel-reactive antibodies (PRA) in maternal sera can also be used to increase the index of suspicion for maternal anti-fetal rejection. The purpose of this study was to determine (i) the frequency of pathologic lesions consistent with maternal anti-fetal rejection in term and spontaneous preterm births; (ii) the fetal serum concentration of CXCL10 in patients with and without evidence of maternal anti-fetal rejection; and (iii) the fetal blood transcriptome and proteome in cases with a fetal inflammatory response associated with maternal anti-fetal rejection. Maternal and fetal sera were obtained from normal term (n = 150) and spontaneous preterm births (n = 150). A fetal inflammatory response associated with maternal anti-fetal rejection was diagnosed when the patients met two or more of the following criteria: (i) presence of chronic placental inflammation; (ii) ≥80% of maternal HLA class I PRA positivity; and (iii) fetal serum CXCL10 concentration >75th percentile. Maternal HLA PRA was analyzed by flow cytometry. The concentrations of fetal CXCL10 and IL-6 were determined by ELISA. Transcriptome analysis was undertaken after the extraction of total RNA

    The quality of fetal growth and development predicts the risk for a range of noncommunicable, chronic illnesses. These observations form the basis of the "developmental origins of health and disease" hypothesis, which suggests that the intrauterine signals that compromise fetal growth also act to "program" tissue differentiation in a manner that predisposes to later illness. Fetal growth also predicts the risk for later psychopathology. These findings parallel studies showing that antenatal maternal emotional well-being likewise predicts the risk for later psychopathology. Taken together, these findings form the basis for integrative models of fetal neurodevelopment, which propose that antenatal maternal adversity operates through the biological pathways associated with fetal growth to program neurodevelopment. The authors review the literature and find little support for such integrated models. Maternal anxiety, depression, and stress all influence neurodevelopment but show modest, weak, or no associations with known stress mediators (e.g., glucocorticoids) or with fetal growth. Rather, compromised fetal development appears to establish a "meta-plastic" state that increases sensitivity to postnatal influences. There also remain serious concerns that observational studies associating either fetal growth or maternal mental health with neurodevelopmental outcomes fail to account for underlying genetic factors. Finally, while the observed relation between fetal growth and adult health has garnered considerable attention, the clinical relevance of these associations remains to be determined. There are both considerable promise and important challenges for future studies of the fetal origins of mental health.

    Well-being or quality of life is thought to give a more accurate picture of the impact a condition has on day-to-day functioning than traditional outcome measures. This study sought to examine the relationship between engagement in play and well-being for preschool children with and without developmental coordination disorder (DCD). A quasi-experimental design was used with two independent groups of preschool children aged 4-6 years with (n=32) and without (n=31) probable DCD. Play skills were assessed using the Play Observation Scale based on 30min of videotape of free-play at preschool. Well-being was assessed using a parent-proxy version of the Revised Children Quality of Life Questionnaire (KINDL(R)). Spearman rho correlations were performed to examine the relationship between play and well-being. Well-being at preschool was significantly lower for the children in the DCD group however overall well-being was not significantly different. Engagement in type of social play (solitary, parallel or group) was found to predict well-being for the typically developing children. For the children with DCD, engagement in group play was not associated with well-being. An explanation for this difference may be that children with DCD may not experience free-play at preschool as "play" but rather as hard work. Further research is needed to determine why children with DCD experience lower well-being at preschool than their peers and to investigate children's perceptions of free-play. This may enable teachers and therapists to better support children with DCD in the preschool environment. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Background: Ultrasound observation of fetal movement has documented general trends in motor development and fetal age when motor response to stimulation is observed. Evaluation of fetal movement quality, in addition to specific motor activity, may improve documentation of motor development and highlight specific motor responses to stimulation. Aims: The aim of this investigation was to assess fetal movement at 26 and 36 weeks gestation during three conditions (baseline, immediate response to vibro-acoustic stimulation (VAS, and post-response. Design: A prospective, longitudinal design was utilized. Subjects: Twelve normally developing fetuses, 8 females and 4 males, were examined with continuous ultrasound imaging. Outcome measures: The Fetal Neurobehavioral Coding System (FENS was used to evaluate the quality of motor activity during 10-second epochs over the three conditions. Results: Seventy-five percent of the fetuses at the 26 week assessment and 100% of the fetuses at the 36 week assessment responded with movement immediately following stimulation. Significant differences in head, fetal breathing, general, limb, and mouthing movements were detected between the 26 week and 36 week assessments. Movement differences between conditions were detected in head, fetal breathing, limb, and mouthing movements. Conclusions: Smoother and more complex movement was observed with fetal maturation. Following VAS stimulation, an immediate increase of large, jerky movements suggest instability in fetal capabilities. Fetal movement quality changes over gestation may reflect sensorimotor synaptogenesis in the central nervous system, while observation of immature movement patterns following VAS stimulation may reflect movement pattern instability.

    Fetal movement is an important biological index of fetal well-being. Since 2008, we have been developing an original capacitive acceleration sensor and device that a pregnant woman can easily use to record fetal movement by herself at home during sleep. In this study, we report a newly developed automated software system for analyzing recorded fetal movement. This study will introduce the system and compare its results to those of a manual analysis of the same fetal movement signals (Experiment I). We will also demonstrate an appropriate way to use the system (Experiment II). In Experiment I, fetal movement data reported previously for six pregnant women at 28-38 gestational weeks were used. We evaluated the agreement of the manual and automated analyses for the same 10-sec epochs using prevalence-adjusted bias-adjusted kappa (PABAK) including quantitative indicators for prevalence and bias. The mean PABAK value was 0.83, which can be considered almost perfect. In Experiment II, twelve pregnant women at 24-36 gestational weeks recorded fetal movement at night once every four weeks. Overall, mean fetal movement counts per hour during maternal sleep significantly decreased along with gestational weeks, though individual differences in fetal development were noted. This newly developed automated analysis system can provide important data throughout late pregnancy.

    Maternal perception of decreased fetal movements is a specific indicator of fetal compromise, notably in the context of poor fetal growth. There is currently no agreed numerical definition of decreased fetal movements, with the subjective perception of a decrease on the part of the mother being the most significant definition clinically. Both qualitative and quantitative aspects of fetal activity may be important in identifying the compromised fetus.Yet, how pregnant women perceive and describe fetal activity is under-investigated by qualitative means. The aim of this study was to explore normal fetal activity, through first-hand descriptive accounts by pregnant women. Using qualitative descriptive methodology, interviews were conducted with 19 low-risk women experiencing their first pregnancy, at two timepoints in their third trimester. Interview transcripts were later analysed using qualitative content analysis and patterns of fetal activity identified were then considered along-side the characteristics of the women and their birth outcomes. This paper focuses on a novel finding; the description by pregnant women of fetal behaviour indicative of hunger and satiation. Full findings will be presented in later papers. Most participants (74% 14 of 19) indicated mealtimes were a time of increased fetal activity. Eight participants provided detailed descriptions of increased activity around meals, with seven (37% 7 of 19) of these specifying increased fetal activity prior to meals or in the context of their own hunger. These movements were interpreted as a fetal demand for food often prompting the mother to eat. Interestingly, the women who described increased fetal activity in the context of hunger subsequently gave birth to smaller infants (mean difference 364 gm) than those who did not describe a fetal response to hunger. Food seeking behaviour may have a pre-birth origin. Maternal-fetal interaction around mealtimes could constitute an endocrine mediated

    The goal of this study was to determine the relationship between individual well-being and risk of a hospital event in the subsequent year. The authors hypothesized an inverse relationship in which low well-being predicts higher likelihood of hospital use. The study specifically sought to understand how well-being segments and demographic variables interact in defining risk of a hospital event (inpatient admission or emergency room visit) in an employed population. A retrospective study design was conducted with data from 8835 employees who completed a Well-Being Assessment questionnaire based on the Gallup-Healthways Well-Being Index. Cox proportional hazards models were used to examine the impact of Individual Well-Being Score (IWBS) segments and member demographics on hazard ratios (HRs) for a hospital event during the 12 months following assessment completion. Significant main effects were found for the influence of IWBS segments, sex, education, and relationship status on HRs of a hospital event, but not for age. However, further analysis revealed significant interactions between age and IWBS segments (P=0.005) and between age and sex (Pwell-being and higher risk of an event in employees ages 44 years and older is mitigated in younger age groups. These results suggest that youth attenuates the risk engendered in poor well-being; therefore, methods to maintain or improve well-being as individuals age presents a strong opportunity for reducing hospital events.

    Porcine placenta has been utilized as a model for elucidating contributions of both fetal and maternal tissues to metabolic activity of the placenta in response to a variety of stresses. Alloxan diabetes, food restriction and genetic obesity all produced alterations in placental metablolism with differences in responses of fetal and maternal placentas. Further analysis of nutrient untilization by the placenta produced dramatic differences in the partitioning of substrates by fetal and maternal tissues during placental development. Metabolic activity of maternal tissue contributed to overall placental metabolic activity to a greater degree than fetal tissue. However, experiments with in utero fetal decapitation indicated that some of differences between fetal and maternal placental metabolic activity may be due to the influence of fetal regulatory mechanisms. Maternal endometrium plays a critical role in metabolic response of uteroplacenta and thus availability of nutrients to the fetus and fetal placenta. Differences in metabolic development of fetal and maternal tissues suggested that regulation of placental metabolism may originate from fetal as well as maternal sources

    Effective detection and management of fetal growth restriction is relevant to all obstetric care providers. Models of best practice to care for these patients and their families continue to evolve. Since much of the disease burden in fetal growth restriction originates in the placenta, the concept of a multidisciplinary placenta clinic program, managed primarily within a maternal-fetal medicine division, has gained popularity. In this context, fetal growth restriction is merely one of many placenta-related disorders that can benefit from an interdisciplinary approach, incorporating expertise from specialist perinatal ultrasound and magnetic resonance imaging, reproductive genetics, neonatal pediatrics, internal medicine subspecialties, perinatal pathology, and nursing. The accurate diagnosis and prognosis for women with fetal growth restriction is established by comprehensive clinical review and detailed sonographic evaluation of the fetus, combined with uterine artery Doppler and morphologic assessment of the placenta. Diagnostic accuracy for placenta-mediated fetal growth restriction may be enhanced by quantification of maternal serum biomarkers including placenta growth factor alone or combined with soluble fms-like tyrosine kinase-1. Uterine artery Doppler is typically abnormal in most instances of early-onset fetal growth restriction and is associated with coexistent preeclampsia and underlying maternal vascular malperfusion pathology of the placenta. By contrast, rare but potentially more serious underlying placental diagnoses, such as massive perivillous fibrinoid deposition, chronic histiocytic intervillositis, or fetal thrombotic vasculopathy, may be associated with normal uterine artery Doppler waveforms. Despite minor variations in placental size, shape, and cord insertion, placental function remains, largely normal in the general population. Consequently, morphologic assessment of the placenta is not currently incorporated into current screening

    effect of maternal, socioeconomic and obstetric variables, as well the presence of artery incisions in the 20th and 24th weeks on the fetal weight estimated at the end of pregnancy (36th week in pregnant women attended by Programa Saúde da Família, in an inland town of the northeast of Brazil. METHODS: a longitudinal study including 137 pregnant women, who have been followed up every four weeks in order to assess clinical, socioeconomic and obstetric conditions, including their weight. The uterine arteries were evaluated by Doppler in the 20th and 24th weeks, the fetal weight and the amniotic fluid index (AFI, determined in the 36th week. The initial maternal nutritional state has been determined by the body mass index (BMI, the pregnant women being classified as low weight, eutrophic, over weight and obese. Weight gain during gestation has been evaluated, according to the initial nutritional state, being classified at the end of the second and third trimester as insufficient, adequate and excessive weight gain. Analysis of variance was performed to evaluate the association of the fetal weight in the 36th week with the predictor variables, adjusted by multiple linear regression. RESULTS: an association between the fetal weight estimated in the 36th week and the mother's age (p=0.02, mother's job (p=0.02, initial nutritional state (p=0.04, weight gain in the second trimester (p=0.01, presence of incisions in the uterine arteries (p=0.02, and AFI (p=0.007 has been observed. The main factors associated to the fetal weight estimated in the 36th week, after the multiple regression analysis were: BMI at the pregnancy onset, weight gain in the second trimester, AFI and tabagism. CONCLUSIONS: in the present study, the fetal weight is positively associated with the initial maternal nutritional state, the weight gain in the second trimester and the volume of amniotic fluid, and negatively, to tabagism.

    Full Text Available Research has established that individuals who provide personal therapy to others should have stable personal and professional lives, and possess a keen and accurate perception of wellness. Unfortunately, sometimes students pursuing careers in counseling and psychotherapy have unresolved psychological issues that, if unresolved, could later affect them in their professional lives. Thus, the purpose of the study was to understand psychological well-being and perceived wellness in a sample of graduate students (N = 97 preparing to become counselors in a CACREP-accredited counseling program at a state university in Pennsylvania. It measured the participants' psychological well- being by the Scales of Psychological Well-Being (SPWB and their perception of wellness by the Perceived Wellness Survey (PWS. Multiple regression analysis revealed a significant relationship between psychological well-being and perceived wellness of counselors-in-training. The results of this study could have implications for additional problems such as the failure of self-care among counselors or the nonexistence or nonuse of adequate wellness assessment tools during counselor development.

    Full Text Available Arachidonic acid (AA; C20∶4 n-6 and docosahexaenoic acid (DHA; C22∶6 n-3 are important long-chain polyunsaturated fatty acids (LC-PUFA in maintaining pancreatic beta-cell structure and function. Newborns of gestational diabetic mothers are more susceptible to the development of type 2 diabetes in adulthood. It is not known whether low circulating AA or DHA is involved in perinatally "programming" this susceptibility. This study aimed to assess whether circulating concentrations of AA, DHA and other fatty acids are associated with fetal insulin sensitivity or beta-cell function, and whether low circulating concentrations of AA or DHA are involved in compromised fetal insulin sensitivity in gestational diabetic pregnancies.In a prospective singleton pregnancy cohort, maternal (32-35 weeks gestation and cord plasma fatty acids were assessed in relation to surrogate indicators of fetal insulin sensitivity (cord plasma glucose-to-insulin ratio, proinsulin concentration and beta-cell function (proinsulin-to-insulin ratio in 108 mother-newborn pairs. Cord plasma DHA levels (in percentage of total fatty acids were lower comparing newborns of gestational diabetic (n = 24 vs. non-diabetic pregnancies (2.9% vs. 3.5%, P = 0.01. Adjusting for gestational age at blood sampling, lower cord plasma DHA levels were associated with lower fetal insulin sensitivity (lower glucose-to-insulin ratio, r = 0.20, P = 0.036; higher proinsulin concentration, r = -0.37, P <0.0001. The associations remained after adjustment for maternal and newborn characteristics. Cord plasma saturated fatty acids C18∶0 and C20∶0 were negatively correlated with fetal insulin sensitivity, but their levels were not different between gestational diabetic and non-diabetic pregnancies. Cord plasma AA levels were not correlated with fetal insulin sensitivity.Low circulating DHA levels are associated with compromised fetal insulin sensitivity, and may be involved in

    Fetal exposure to polychlorinated biphenyls (PCBs), polychlorinated-p-dibenzodioxins (PCDDs), and polychlorinated dibenzofurans (PCDFs) have been associated with a number of adverse health outcomes. Although the placenta acts as a barrier between the mother and the fetus, these contaminants transfer through the placenta exposing the fetus. Several studies have investigated placental transfer, but few have assessed the co-variation among these contaminants. Maternal blood, cord blood, and cord tissue were collected from 41 Japanese mother-infant pairs and analyzed for dioxin-like PCBs and PCDD/Fs. Hierarchical cluster analysis followed by principal component analysis were used to assess the co-variation. Two stable clusters of dioxin-like PCBs were found in maternal and cord blood. One cluster of low/medium chlorinated dioxin-like PCBs was present in all three matrices with 2,3',4,4',5-PeCB(#118) and 3,3',4,4',5-PeCB(#126) explaining the majority of the clusters' variances. Medium/high chlorinated dioxin-like PCBs clustered in maternal blood and cord blood but not in cord tissue. 2,3,4,4',5-PeCB(#114) and 2,3,3',4,4',5,5'-HpCB(#189) explained the majority of the clusters' variances. There was a substantial correlation between the sum of dioxin-like PCBs and total PCDD/F in all three matrices. The sum of the four suggested PCBs plus 3,3',4,4'-TeCB(#77) correlated well with total PCDD/F in all three matrices. Apart from the dioxin-like PCBs, little co-variation existed among the studied contaminants. The five PCBs can be used as fetal exposure markers for dioxin and dioxin-like PCBs in maternal and cord blood respectively. In cord tissue, more higher chlorinated dioxin-like PCBs need to be measured as well.

    2013-01-01

    Autoimmune thyroid diseases (AITD) show a female predominance, with an increased incidence in the years following parturition. Fetal microchimerism has been suggested to play a role in the pathogenesis of AITD. However, only the presence of fetal microchimeric cells in blood and in the thyroid gland of these patients has been proven, but not an actual active role in AITD. Is fetal microchimerism harmful for the thyroid gland by initiating a Graft versus Host reaction (GvHR) or being the target of a Host versus Graft reaction (HvGR)? Is fetal microchimerism beneficial for the thyroid gland by being a part of tissue repair or are fetal cells just innocent bystanders in the process of autoimmunity? This review explores every hypothesis concerning the role of fetal microchimerism in AITD. PMID:23723083

    Physical impairments affect a substantial number of older adults in the United States, with rates increasing with advancing age. Impairment is linked with compromised well-being, although the reasons are not fully understood. We explore the extent to which linkages between impairment severity and well-being are accounted for by older adults' daily activities. We speculate that activities may influence global appraisals of well-being by offering the opportunity to fulfill productive and social roles and may influence daily emotions by shaping the context (places, people) in which life occurs. We examine the effects of impairment severity on life satisfaction and four diary-based experienced well-being measures (happiness, frustration, worry, and sadness). Data are from the Disability and Use of Time supplement to the Panel Study of Income Dynamics ( n = 1,606), a national sample of adults ages 60 years and older in the United States. We estimate nested regression models, taking into account within-person correlations for experienced well-being. Impairment severity is associated with poorer assessments of life satisfaction and all four dimensions of experienced well-being. Activity measures, which encompass eight productive (e.g., household chores) and three leisure (e.g., socializing) activities, account for 10% of the association between impairment and life satisfaction, and virtually none of the association between impairment and experienced well-being. However, psychosocial factors including higher neuroticism, lower self-efficacy, and poorer quality social relationships account for a sizeable share of the associations. Role-fulfilling aspects of activities appear to be more central than contextual aspects of activities to the impairment-well-being relationship. However, potentially modifiable psychosocial factors account for a much greater share of this relationship. Further research is needed on whether interventions targeting these psychosocial factors might

    Infection by bacteria, viruses and parasites may lead to fetal death, organ injury or limited sequelae depending on the pathogen. Here we consider the role of infection during pregnancy on fetal development including placental development and function, which can lead to fetal growth restriction. The classic group of teratogenic pathogens are referred to as “TORCH” (Toxoplasma gondii, Others like Treponema pallidum, Rubella virus, Cytomegalovirus, Herpes simplex virus), but should include a much broader group of pathogens including Parvovirus B19, Varicella zoster virus, and Plasmodium falciparum to name a few. In this review, we describe the influence of different infections in utero on fetal development and the short- and long-term outcomes for the neonate. In some cases, the mechanisms used by these pathogens to disrupt fetal development are well known. Bacterial infection of the developing fetal lungs and brain begins with inflammatory cascade resulting in cytokine injury and oxidative stress. For some pathogens like P. falciparum, the mechanisms involve oxidative stress and apoptosis to disrupt placental and fetal growth. An in utero infection may also impact the long-term health of the infant; in many cases, a viral infection in utero increases the risk of developing Type 1 diabetes in childhood. Understanding the varied mechanisms employed by these pathogens may enable therapies to attenuate changes in fetal development, decrease preterm birth, and improve survival. PMID:23884862

    Full Text Available The most well known reproductive consequence of residence at high altitude (HA >2700 m is reduction in fetal growth. Reduced fetoplacental oxygenation is an underlying cause of pregnancy pathologies, including intrauterine growth restriction and preeclampsia, which are more common at HA. Therefore, altitude is a natural experimental model to study the etiology of pregnancy pathophysiologies. We have shown that the proximate cause of decreased fetal growth is not reduced oxygen availability, delivery, or consumption. We therefore asked whether glucose, the primary substrate for fetal growth, might be decreased and/or whether altered fetoplacental glucose metabolism might account for reduced fetal growth at HA.Doppler and ultrasound were used to measure maternal uterine and fetal umbilical blood flows in 69 and 58 residents of 400 vs 3600 m. Arterial and venous blood samples from mother and fetus were collected at elective cesarean delivery and analyzed for glucose, lactate and insulin. Maternal delivery and fetal uptakes for oxygen and glucose were calculated.The maternal arterial - venous glucose concentration difference was greater at HA. However, umbilical venous and arterial glucose concentrations were markedly decreased, resulting in lower glucose delivery at 3600 m. Fetal glucose consumption was reduced by >28%, but strongly correlated with glucose delivery, highlighting the relevance of glucose concentration to fetal uptake. At altitude, fetal lactate levels were increased, insulin concentrations decreased, and the expression of GLUT1 glucose transporter protein in the placental basal membrane was reduced.Our results support that preferential anaerobic consumption of glucose by the placenta at high altitude spares oxygen for fetal use, but limits glucose availability for fetal growth. Thus reduced fetal growth at high altitude is associated with fetal hypoglycemia, hypoinsulinemia and a trend towards lactacidemia. Our data support that

    Because of the superior tissue contrast, high spatial resolution, and multiplanar capabilities, fetal magnetic resonance imaging (MRI) can depict fetal brain pathologies with high accuracy. Pathological fetal brain development may result from malformations or acquired conditions. Differentiation of these etiologies is important with respect to managing the actual pregnancy or counseling future pregnancies. As a widened ventricular system is a common hallmark of both maldevelopment and acquired conditions, it may cause problems in the differential diagnosis. Fetal MRI can provide detailed morphological information, which allows refinement of the diagnosis of ventricular enlargement in a large number of cases. Systematic work-up of morphological details that may be recognized on MR images provides an approach for achieving a correct diagnosis in cases of ventricle enlargement. (orig.)

    Psychological well-being is recognized as an important health component, which influences the behavior, ability to cope with stressful events, work performance, and generally the ability to achieve one's full potential. To comparatively assess the psychological well-being of dental students during the summer semester examination period and summer holiday. A single-arm, prospective study was conducted in second year dental students from the Faculty of Dental Medicine, Bucharest. The psychological well-being was assessed using the WHO-Five Well-being Index. Students' psychological well-being was statistically significantly better during the summer holiday (median=19) than during the summer semester examination period (median = 11.5), Z = 3.69, p holiday, but it was significantly correlated with the WHO-Five Well-being Index score corresponding to the summer holiday, and no association was observed with the WHO-Five Well-being Index score corresponding to the summer semester examination period. Within the limits of this study, psychological well-being is likely to be negatively influenced, on a fairly large scale, by the semester examination period. Therefore, it is recommended to identify the most appropriate methods of examination with regards to the psychological load that might be a threat to the validity of students' evaluation. Additionally, training students about adequate coping strategies, designed as interventions at individual or group level, may be required.

    Abstract The goal of this study was to determine the relationship between individual well-being and risk of a hospital event in the subsequent year. The authors hypothesized an inverse relationship in which low well-being predicts higher likelihood of hospital use. The study specifically sought to understand how well-being segments and demographic variables interact in defining risk of a hospital event (inpatient admission or emergency room visit) in an employed population. A retrospective study design was conducted with data from 8835 employees who completed a Well-Being Assessment questionnaire based on the Gallup-Healthways Well-Being Index. Cox proportional hazards models were used to examine the impact of Individual Well-Being Score (IWBS) segments and member demographics on hazard ratios (HRs) for a hospital event during the 12 months following assessment completion. Significant main effects were found for the influence of IWBS segments, sex, education, and relationship status on HRs of a hospital event, but not for age. However, further analysis revealed significant interactions between age and IWBS segments (P=0.005) and between age and sex (Pwell-being and higher risk of an event in employees ages 44 years and older is mitigated in younger age groups. These results suggest that youth attenuates the risk engendered in poor well-being; therefore, methods to maintain or improve well-being as individuals age presents a strong opportunity for reducing hospital events.

    One of the many objectives of the European Union's SOLO (Epidemiological Studies of Exposed Southern Urals Populations) project is to quantify the radiation dose-response following chronic in utero exposures to ionizing radiation. The project is presently conducting a pooled analysis of two cohorts of individuals born to exposed mothers - the Techa River Offspring Cohort (TROC) and the Ozyorsk Offspring Cohort (OOC). The TROC includes the offspring of mothers with external exposures to contaminated riverbanks and internal ingestions of 89 Sr, 90 Sr/ 90 Y, and 137 Cs/ 137m Ba, while the OOC includes the offspring of mothers with external exposures seen within the Mayak plutonium production facilities and internal inhalation of 239 Pu and possibly 131 I. In the present study, a newly created Urals-based series of fetal and maternal models is employed to assess S values for all seven radionuclides. Among all fetal ages, S values ranged in magnitude from 10 -14 to 10 -10 Gy per Bq-s for fetal source organs and from 10 -18 to 10 -14 Gy per Bq-s from maternal source organs, depending upon particle type, particle energy, and fetal age. For a given radionuclide and fetal age, S values for fetal source organs were approximately two orders of magnitude higher than for maternal source organs. Little variation in S values was observed among fetal source organs, while variations of over 100 % with respect to the mean were observed for maternal source organs near the fetus. S value variations from maternal cross-fire were highly dependent on fetal position and separation distance from the maternal source organ. These radionuclide S values have been coupled with biokinetic models for use in cohort dose assessment within the SOLO project. (orig.)

MÉTODOS: estudo tipo caso-controle composto por 188 recém-nascidos, sendo que 47 compuseram o grupo casos (pH de artéria umbilical OBJECTIVES: to assess maternal risk factors associated with fetal acidosis. METHODS: a case-control type study was conducted of 188 neonates, of whom 47 comprised the case group (umbilical arterial pH <7.0 and 141 the control (umbilical arterial pH E7.1 <7.3. The study included only single-gestation neonates without congenital malformations. Both maternal and fetal variables were taken into consideration. Statistical analysis involved the calculation of the raw and adjusted Odds Ratio, Student's t-test, the chi-squared test and multivariate analysis using Enter-method non-conditional logistic regression. The level of statistical significance was set at p<0.05. RESULTS: in the case group higher percentages of caesarian sections and pre-term births were observed, involving almost five times as much intensive care and twenty-five times more likelihood of Apgar in the 5th minute <7. No association was observed between the groups and fetal presentation, mother's age, history of miscarriage, years of schooling of mother or attendance at prenatal sessions. After multivariate analysis, the only risk factors that remained significant were complications relating to the placenta or the umbilical cord. Deliveries involving complications relating to the placenta or the umbilical cord were three times more likely to involve fetal acidemia. CONCLUSIONS: acidemia among neonates was associated with a higher percentage of caesarians, premature births, a need for intensive care and treatment and an Apgar index of <7 in the 5th minute. After multivariate analysis, complications relating to premature displacement of the placenta and the umbilical cord were the only remaining risk factors associated with fetal acidemia.

  9. Fetal and neonatal thyrotoxicosis

    2013-01-01

    Fetal thyrotoxicosis is a rare disease occurring in 1 out of 70 pregnancies with Grave's disease or in 1 out of 4000-50,000 deliveries. The mortality is 12-20%, usually from heart failure, but other complications are tracheal compression, infections and thrombocytopenia. It results from transfer of thyroid stimulating immunoglobulins from mother to fetus through the placenta. This transplacental transfer begins around 20th week of pregnancy and reaches its maximum by 30th week. These autoantibodies bind to the fetal thyroid stimulating hormone (TSH) receptors and increase the secretion of the thyroid hormones. The mother has an active autoimmune thyroid disease or has been treated for it in the past. She may be absolutely euthyroid due to past treatment by drugs, surgery or radioiodine ablation, but still have active TSH receptor stimulating autoantibodies, which can cause fetal thyrotoxicosis. The other features of this disease are fetal tachycardia, fetal goiter and history of spontaneous abortions and findings of goiter, ascites, craniosyntosis, fetal growth retardation, maceration and hydrops at fetal autopsy. If untreated, this disease can result in intrauterine death. The treatment for this disease consists of giving carbimazole to the mother, which is transferred through the placenta to the fetus. The dose of carbimazole is titrated with the fetal heart rate. If the mother becomes hypothyroid due to carbimazole, thyroxine is added taking advantage of the fact that very little of thyroxine is transferred across the placenta. Neonatal thyrotoxicosis patients are very sick and require emergency treatment. The goal of the treatment is to normalize thyroid functions as quickly as possible, to avoid iatrogenic hypothyroidism while providing management and supportive therapy for the infant's specific signs and symptoms.

    Full Text Available Fetal movement is an important biological index of fetal well-being. Since 2008, we have been developing an original capacitive acceleration sensor and device that a pregnant woman can easily use to record fetal movement by herself at home during sleep. In this study, we report a newly developed automated software system for analyzing recorded fetal movement. This study will introduce the system and compare its results to those of a manual analysis of the same fetal movement signals (Experiment I. We will also demonstrate an appropriate way to use the system (Experiment II. In Experiment I, fetal movement data reported previously for six pregnant women at 28-38 gestational weeks were used. We evaluated the agreement of the manual and automated analyses for the same 10-sec epochs using prevalence-adjusted bias-adjusted kappa (PABAK including quantitative indicators for prevalence and bias. The mean PABAK value was 0.83, which can be considered almost perfect. In Experiment II, twelve pregnant women at 24-36 gestational weeks recorded fetal movement at night once every four weeks. Overall, mean fetal movement counts per hour during maternal sleep significantly decreased along with gestational weeks, though individual differences in fetal development were noted. This newly developed automated analysis system can provide important data throughout late pregnancy.

    Traditional methods of dating a pregnancy based on history or sonographic assessment have a large variation in the third trimester. We aimed to assess the ability of various quantitative measures of brain cortical folding on MR imaging in determining fetal gestational age in the third trimester. We evaluated 8 different quantitative cortical folding measures to predict gestational age in 33 healthy fetuses by using T2-weighted fetal MR imaging. We compared the accuracy of the prediction of gestational age by these cortical folding measures with the accuracy of prediction by brain volume measurement and by a previously reported semiquantitative visual scale of brain maturity. Regression models were constructed, and measurement biases and variances were determined via a cross-validation procedure. The cortical folding measures are accurate in the estimation and prediction of gestational age (mean of the absolute error, 0.43 ± 0.45 weeks) and perform better than (P = .024) brain volume (mean of the absolute error, 0.72 ± 0.61 weeks) or sonography measures (SDs approximately 1.5 weeks, as reported in literature). Prediction accuracy is comparable with that of the semiquantitative visual assessment score (mean, 0.57 ± 0.41 weeks). Quantitative cortical folding measures such as global average curvedness can be an accurate and reliable estimator of gestational age and brain maturity for healthy fetuses in the third trimester and have the potential to be an indicator of brain-growth delays for at-risk fetuses and preterm neonates. © 2015 by American Journal of Neuroradiology.

    Full Text Available Evidence of the short term relationship between maternal and fetal heart rates has been found in previous studies. However there is still limited knowledge about underlying mechanisms and patterns of the coupling throughout gestation. In this study, Transfer Entropy (TE was used to quantify directed interactions between maternal and fetal heart rates at various time delays and gestational ages. Experimental results using maternal and fetal electrocardiograms showed significant coupling for 63 out of 65 fetuses, by statistically validating against surrogate pairs. Analysis of TE showed a decrease in transfer of information from fetus to the mother with gestational age, alongside the maturation of the fetus. On the other hand, maternal to fetal TE was significantly greater in mid (26-31 weeks and late (32-41 weeks gestation compared to early (16-25 weeks gestation (Mann Whitney Wilcoxon (MWW p<0.05. TE further increased from mid to late, for the fetuses with RMSSD of fetal heart rate being larger than 4 msec in the late gestation. This difference was not observed for the fetuses with smaller RMSSD, which could be associated with the quiet sleep state. Delay in the information transfer from mother to fetus significantly decreased (p = 0.03 from mid to late gestation, implying a decrease in fetal response time. These changes occur concomitant with the maturation of the fetal sensory and autonomic nervous systems with advancing gestational age. The effect of maternal respiratory rate derived from maternal ECG was also investigated and no significant relationship was found between breathing rate and TE at any lag. In conclusion, the application of TE with delays revealed detailed information on the fetal-maternal heart rate coupling strength and latency throughout gestation, which could provide novel clinical markers of fetal development and well-being.

    2011-06-01

    Because there has been a lack of a single comprehensive measure for assessing workplace well-being, we elected to develop such a self-report measure. Provisional items were extracted from the literature on "positive psychology" and were adapted to capture their workplace application. The provisional 50-item set was completed by a nonclinical sample of 150 adults. A second and third sample was recruited to examine its reliability and any impact of depressed mood and sociodemographic and work-related variables, respectively. Factor analysis identified four domains, "Work Satisfaction," "Organizational Respect for the Employee," "Employer Care," and a negative construct-"Intrusion of Work into Private Life." High test-retest reliability was demonstrated for the final 31-item measure, whereas there was no distinct impact of depressed mood on the scale scores. Work Satisfaction scale scores were influenced by job type. Gender effects were found for two of the four scales, whereas a longer period of employment inversely linked to Organizational Respect for the Employee and Employer Care scores and was conversely associated with higher Intrusion of Work into Private Life scores. The refined measure should enable individuals and employers to quantify the levels of support and well-being provided by employing organizations.

  18. Maternal–Fetal Nutrient Transport in Pregnancy Pathologies: The Role of the Placenta

    Directory of Open Access Journals (Sweden)

    Kendra Elizabeth Brett

    2014-09-01

    Full Text Available Appropriate in utero growth is essential for offspring development and is a critical contributor to long-term health. Fetal growth is largely dictated by the availability of nutrients in maternal circulation and the ability of these nutrients to be transported into fetal circulation via the placenta. Substrate flux across placental gradients is dependent on the accessibility and activity of nutrient-specific transporters. Changes in the expression and activity of these transporters is implicated in cases of restricted and excessive fetal growth, and may represent a control mechanism by which fetal growth rate attempts to match availability of nutrients in maternal circulation. This review provides an overview of placenta nutrient transport with an emphasis on macro-nutrient transporters. It highlights the changes in expression and activity of these transporters associated with common pregnancy pathologies, including intrauterine growth restriction, macrosomia, diabetes and obesity, as well as the potential impact of maternal diet. Molecular signaling pathways linking maternal nutrient availability and placenta nutrient transport are discussed. How sexual dimorphism affects fetal growth strategies and the placenta’s response to an altered intrauterine environment is considered. Further knowledge in this area may be the first step in the development of targeted interventions to help optimize fetal growth.

  19. Ethical analysis of non-medical fetal ultrasound.

    2009-09-01

    Obstetric ultrasound is the well-recognized prenatal test used to visualize and determine the condition of a pregnant woman and her fetus. Apart from the clinical application, some businesses have started promoting the use of fetal ultrasound machines for nonmedical reasons. Non-medical fetal ultrasound (also known as 'keepsake' ultrasound) is defined as using ultrasound to view, take a picture, or determine the sex of a fetus without a medical indication. Notwithstanding the guidelines and warnings regarding ultrasound safety issued by governments and professional bodies, the absence of scientifically proven physical harm to fetuses from this procedure seems to provide these businesses with grounds for rapid expansion. However, this argument is too simplistic because current epidemiological evidence is not synchronous with advancing ultrasound technology. As non-medical fetal ultrasound has aroused very significant public attention, a thorough ethical analysis of this topic is essential. Using a multifaceted approach, we analyse the ethical perspective of non-medical fetal ultrasound in terms of the expectant mother, the fetus and health professionals. After applying four major theories of ethics and principles (the precautionary principle; theories of consequentialism and impartiality; duty-based theory; and rights-based theories), we conclude that obstetric ultrasound practice is ethically justifiable only if the indication for its use is based on medical evidence. Non-medical fetal ultrasound can be considered ethically unjustifiable. Nevertheless, the ethical analysis of this issue is time dependent owing to rapid advancements in ultrasound technology and the safety issue. The role of health professionals in ensuring that obstetric ultrasound is an ethically justifiable practice is also discussed.

    The macrosomia is an obstetric eventuality associated to high maternal-fetal morbidity-mortality. This assay was planned in order to know the incidence of macrosomia in our institution, the relation between vaginal and abdominal deliveries and the fetal-maternal morbidity we reviewed 3590 records and we found 5.6% incidence of macrosomia in the global obstetric population. There was 58% of vaginal deliveries, 68% of the newborn were male. The main complications were in the C. sections, 2 laceration of the hysterectomy, and 2 peroperative atonias. In the vaginal deliveries, the lacerations of III and IV grade were 9 of each grade. The main fetal complications were 5 slight to severe asphyxia and 4 shoulder dystocias. This assay concludes that the macrosomia in our service is similar to the already published ones, a 42% were C. section and the maternal-fetal morbidity was low.

    Full Text Available In human pregnancy, fetal well-being depends on the development of placental villi and the creation and maintenance of fetal microvessels within them. The aim of this study was to define stereological measures of the growth, capillarization and maturation of villi and of fetoplacental angiogenesis and capillary remodelling. Placentas were collected at 12-41 weeks of gestation and assigned to six age groups spanning equal age ranges. Tissue samples were randomised for position and orientation. Overall growth of peripheral (intermediate and terminal villi and their capillaries was evaluated using total volumes, surface areas and lengths. Measures of villous capillarization comprised capillary volume, surface and length densities and capillary:villus surface and length ratios. Size and shape remodelling of villi and capillaries was assessed using mean cross-sectional areas, perimeters and shape coefficients (perimeter2/area. Group comparisons were drawn by analysis of variance. Villous and capillary volumes, surfaces and lengths increased significantly throughout gestation. Villous maturation involved phasic (capillary:villus surface and length ratios or progressive (volume, surface and length densities increases in indices of villous capillarization. It also involved isomorphic thinning (cross-sectional areas and perimeters declined but shape coefficients did not alter. In contrast, growth of capillaries did not involve changes in luminal areas or perimeters. The results show that villous growth and fetal angiogenesis involve increases in overall length rather than calibre and that villous differentiation involves increased capillarization. Although they do not distinguish between increases in the lengths versus numbers of capillary segments, other studies have shown that capillaries switch from branching to non-branching angiogenesis during gestation. Combined with maintenance of capillary calibres, these processes will contribute to the reduced

    To investigate the self-gating technique for MR imaging of the fetal heart in a sheep model. MR images of 6 fetal sheep heart were obtained at 1.5T. For self-gating MRI of the fetal heart a cine SSFP in short axis, two and four chamber view was used. Self-gated images were compared with real cardiac triggered MR images (pulse-wave triggering). MRI of the fetal heart was performed using both techniques simultaneously. Image quality was assessed and the left ventricular volume and function were measured and compared. Compared with pulse-wave triggering, the self-gating technique produced slightly inferior images with artifacts. Especially the atrial septum could not be so clearly depicted. The contraction of the fetal heart was shown in cine sequences in both techniques. The average blood volumes could be measured with both techniques with no significant difference: at end-systole 3.1 ml (SD± 0.2), at end-diastole 4.9 ml (±0.2), with ejection fractions at 38.6%, respectively 39%. Both self-gating and pulse-wave triggered cardiac MRI of the fetal heart allowed the evaluation of anatomical structures and functional information. Images obtained by self-gating technique were slightly inferior than the pulse-wave triggered MRI. (orig.)

    To investigate whether the fetal thyroid gland could be examined by prenatal ultrasonography and to established the normal range of fetal thyroid width according to the gestational age. The width of the fetal thyroid was determined by prenatal ultrasonography from 118 pregnant women. Three of the mothers had current or previous thyroid disease and the widths of the fetal thyroid were determined from 115 normal subjects. The width of the fetal thyroid was defined by a maximum transverse distance of the thyroid gland between two carotid arteries on transverse scan of the fetal neck. We analyzed the cause of non-measurable cases. The width of the fetal thyroid and Neo-TSH were compared in 19 subjects, including 3 subjects will current or previous thyroid disease. We could measure the fetal thyroid widths in 95 cases (80%). The fetal thyroid widths of mothers without current or previous thyroid disease was 0.9-2.36 cm,which showed linear correlation with gestational age (Y=0.0506 X + 0.0439, r{sup 2}=0.5661). Causes of non-measurable cases were neck flexion (65%), prone position (22%), and overlapped fetal neck by arm or shoulder (13%). Of the 19 neonates with Neo-TSH level, one case had a mother with a thyroid disease and showed increased width of the fetal and high Neo-TSH. The fetal thyroid was measured in 80% of prenatal ultrasonography and the width of the fetal thyroid showed linear correlated with gestational age. We assumed that the width of the thyroid could be useful for diagnosing fetal thyroid disorder when maternal thyroid disease exists.

    To examine the effect that the introduction of new diagnostic technology in obstetric care has had on fetal death. The Medical Birth Registry of Norway provided detailed medical information for approximately 1.2 million deliveries from 1967 to 1995. Information about diagnostic technology was collected directly from the maternity units, using a questionnaire. The data were analyzed using a hospital fixed-effects regression with fetal mortality as the outcome measure. The key independent variables were the introduction of ultrasound and electronic fetal monitoring at each maternity ward. Hospital-specific trends and risk factors of the mother were included as control variables. The richness of the data allowed us to perform several robustness tests. The introduction of ultrasound caused a significant drop in fetal mortality rate, while the introduction of electronic fetal monitoring had no effect on the rate. In the population as a whole, ultrasound contributed to a reduction in fetal deaths of nearly 20 percent. For post-term deliveries, the reduction was well over 50 percent. The introduction of ultrasound made a major contribution to the decline in fetal mortality at the end of the last century. © Health Research and Educational Trust.

    Full Text Available We review the causes of fetal dystocia in cows and buffalo. Two fetal causes are distinct fetal oversize and fetal abnormalities. Fetal oversize is common in heifers, cows of beef cattle breeds, prolonged gestations, increased calf birth weight, male calves and perinatal fetal death with resultant emphysema. Fetal abnormalities include monsters, fetal diseases and fetal maldispositions, and it is difficult to deliver such fetuses because of their altered shape. Although monsters are rare in cattle, a large number of monstrosities have been reported in river buffalo; yet also here, overall incidence is low. Diseases of the fetus resulting in dystocia include hydrocephalus, ascites, anasarca and hydrothorax. The most common cause of dystocia in cattle seems to be fetal maldispositions, of which limb flexion and head deviation appear to be the most frequent. We provide a brief description of the management of dystocia from different causes in cattle and buffalo. A case analysis of 192 and 112 dystocia in cattle and buffalo, respectively, at our referral center revealed that dystocia is significantly higher (P<0.05 in first and second parity cows and buffalo, and that dystocia of fetal origin is common in cows (65.62% but less frequent (40.17% in buffalo. In buffalo, the single biggest cause of dystocia was uterine torsion (53.57%. Fetal survival was significantly (P<0.05 higher both in cows and buffalo when delivery was completed within 12 h of second stage of labor.

    Full Text Available Objective: Our aim is to evaluate the prognostic significance of isolated, preterm decreased fetal movement following normal initial full diagnostic workup. Study design: A retrospective observational study was conducted at a tertiary centre. The applied protocol was approved by the Medical Research Ethics Department of the hospital where the research was conducted. Obstetrics outcomes of preterm- and term-decreased fetal movement were compared following an initial, normal diagnostic work up. Evaluated outcomes were birth weight, mode of delivery, stillbirth rate, induction of labour, development of gestational hypertension, small for gestational age and oligohydramnios, polyhydramnios during the follow up period. Result: Obstetric complications related to placental insufficiency develops more frequently for decreased fetal movement in preterm cases with respect to that of in term cases. Following the diagnosis of decreased fetal movement, pregnancy hypertension occurred in 17% of preterm decreased fetal movement cases and in 4.7% of term decreased fetal movement cases. Fetal growth restriction developed in 6.6% of preterm decreased fetal movement and in 2.3% of term decreased fetal movement. Amniotic fluid abnormalities more frequently developed in preterm decreased fetal movement. Conclusion: Following an initial normal diagnostic workup, preterm decreased fetal movement convey a higher risk for the development of pregnancy complications associated with placental insufficiency. The patient should be monitored closely and management protocols must be developed for initial normal diagnostic workups in cases of preterm decreased fetal movement.

    In early fetal development, the testis secretes – independent of pituitary gonadotropins – androgens and anti-Müllerian hormone (AMH) that are essential for male sex differentiation. In the second half of fetal life, the hypothalamic–pituitary axis gains control of testicular hormone secretion. Follicle-stimulating hormone (FSH) controls Sertoli cell proliferation, responsible for testis volume increase and AMH and inhibin B secretion, whereas luteinizing hormone (LH) regulates Leydig cell androgen and INSL3 secretion, involved in the growth and trophism of male external genitalia and in testis descent. This differential regulation of testicular function between early and late fetal periods underlies the distinct clinical presentations of fetal-onset hypogonadism in the newborn male: primary hypogonadism results in ambiguous or female genitalia when early fetal-onset, whereas it becomes clinically undistinguishable from central hypogonadism when established later in fetal life. The assessment of the hypothalamic–pituitary–gonadal axis in male has classically relied on the measurement of gonadotropin and testosterone levels in serum. These hormone levels normally decline 3–6 months after birth, thus constraining the clinical evaluation window for diagnosing male hypogonadism. The advent of new markers of gonadal function has spread this clinical window beyond the first 6 months of life. In this review, we discuss the advantages and limitations of old and new markers used for the functional assessment of the hypothalamic–pituitary–testicular axis in boys suspected of fetal-onset hypogonadism.

    Congenital diaphragmatic hernia (CDH) is associated with a high mortality, which is mainly due to pulmonary hypoplasia and secondary pulmonary hypertension. In severely affected fetuses, tracheal occlusion (TO) is performed prenatally to reverse pulmonary hypoplasia, because TO leads to accelerated lung growth. Prenatal imaging is important to identify fetuses with pulmonary hypoplasia, to diagnose high-risk fetuses who would benefit from TO, and to monitor the effect of TO after surgery. In fetal imaging, ultrasound (US) is the method of choice, because it is widely available, less expensive, and less time-consuming to perform than magnetic resonance imaging (MRI). However, there are some limitations for US in the evaluation of CDH fetuses. In those cases, MRI is helpful because of a better tissue contrast between liver and lung, which enables evaluation of liver herniation for the diagnosis of a high-risk fetus. MRI provides the ability to determine absolute lung volumes to detect lung hypoplasia. In fetal sheep with normal and hyperplastic lungs after TO, lung growth was assessed on the basis of cross-sectional US measurements, after initial lung volume determination by MRI. To monitor fetal lung growth after prenatal TO, both MRI and US seem to be useful methods.

    Antenatal psychological well-being is multifactorially determined, including by social circumstances. Evidence suggests that workplace conditions are salient determinants of mental health, but it is not known whether employment conditions influence antenatal psychological well-being. To investigate the relationship between employment conditions and antenatal psychological well-being in Australian women. A sociodemographically diverse consecutive cohort of employed nulliparous women was recruited in late pregnancy. Data were collected by a structured interview assessing sociodemographic characteristics, employment arrangements, experience of pregnancy-related discrimination, and access to maternity leave entitlements. Participants completed two standardised psychometric measures of maternal mood: the Edinburgh Depression Scale (EDS) and the Profile of Mood States (PoMS). Comparisons of self-reported mood were made between women by experience of workplace adversity, using a composite measure of workplace events. Of 205 eligible women, 165 agreed to participate. Of these, 114 of 165 (69%) reported at least one form of workplace adversity during pregnancy. More women without private health insurance (78%) reported workplace adversity than those who were privately insured (57%) (chi2(1)=6.95, P=0.008). Women experiencing workplace adversity had significantly worse psychological well-being as indicated by the EDS score (7.7+/-5.1) than those who were experiencing no workplace adversity (5.5+/-3.4), mean difference (95% CI)=-2.2 (-3.7 to -0.8), P=0.003. Similar results were reported for the PoMS. Workplace adversity during pregnancy is associated with poorer maternal psychological well-being. Workplace conditions and entitlements are salient factors for consideration in assessments of antenatal psychosocial well-being.

  12. Fetal body movement monitoring.

    Recording fetal activity serves as an indirect measure of central nervous system integrity and function. The coordination of whole body movement, which requires complex neurologic control, is likely similar to that of the newborn infant. Short-term observations of the fetus are best performed using real-time ultrasound imaging. Monitoring fetal motion has been shown to be clinically worthwhile in predicting impending death or compromise, especially when placental insufficiency is longstanding. The presence of a vigorous fetus is reassuring. Perceived inactivity requires a reassessment of any underlying antepartum complication and a more precise evaluation by fetal heart rate testing or real-time ultrasonography before delivery is contemplated.

    Background: The 20th week gestational age (GA) is at mid-gestation and corresponds to the age at which the termination of pregnancy in several countries and the first Magnetic Resonance Imaging (MRI) can be performed, and at which the premature babies may survive. However, at present, very little is known about the exact anatomical character at this GA. Objective: To delineate the developing fetal brain of 20 weeks GA and obtain the three dimensional visualization model. Materials and methods: 20 fetal specimens were scanned by 3.0 T and 7.0 T post-mortem MRI, and the three dimensional visualization model was obtained with Amira 4.1. Results: Most of the sulci or their anlage, except the postcentral sulcus and intraparietal sulcus, were present. The laminar organization, described as layers with different signal intensities, was most clearly distinguished at the parieto-occipital lobe and peripheral regions of the hippocampus. The basal nuclei could be clearly visualized, and the brain stem and cerebellum had formed their common shape. On the visualization model, the shape and relative relationship of the structures could be appropriately delineated. The ranges of normal values of the brain structures were obtained, but no sexual dimorphisms or cerebral asymmetries were found. Conclusions: The developing fetal brain of 20 weeks GA can be clearly delineated on 3.0 T and 7.0 T post-mortem MRIs, and the three dimensional visualization model supplies great help in precise cognition of the immature brain. These results may have positive influences on the evaluation of the fetal brain in the uterus.

    Starting from the Developmental Origins of Health and Disease (DOHaD) hypotheses proposed by David Barker, namely fetal programming, in the past years, there is a growing evidence of the major role played by epigenetic factors during the intrauterine life and the perinatal period. Furthermore, it has been assessed that these factors can affect the health status in infancy and even in adulthood. In this review, we focus our attention on the fetal programming of the brain, analyzing the most recent literature concerning the epigenetic factors that can influence the development of neuropsychiatric disorders such as bipolar disorders, major depressive disorders, and schizophrenia. The perinatal epigenetic factors have been divided in two main groups: maternal factors and fetal factors. The maternal factors include diet, smoking, alcoholism, hypertension, malnutrition, trace elements, stress, diabetes, substance abuse, and exposure to environmental toxicants, while the fetal factors include hypoxia/asphyxia, placental insufficiency, prematurity, low birth weight, drugs administered to the mother or to the baby, and all factors causing intrauterine growth restriction. A better comprehension of the possible mechanisms underlying the pathogenesis of these diseases may help researchers and clinicians develop new diagnostic tools and treatments to offer these patients a tailored medical treatment strategy to improve their quality of life.

  17. Comparison of rat and rabbit embryo-fetal developmental ...

    Science.gov (United States)

    Regulatory non-clinical safety testing of human pharmaceutical compounds typically requires embryo fetal developmental toxicity (EFDT) testing in two species, (one rodent and one non-rodent, usually the rat and the rabbit). The question has been raised whether under some conditions EFDT testing could be limited to one species, or whether the need for testing in a second species could be decided on a case by case basis. As part of an RIVM/CBG-MEB/HESI/US EPA consortium initiative, we built and queried a database of 379 EFDT studies conducted for marketed and non-marketed pharmaceutical compounds. The animal models (rat and rabbit) were assessed for their potential for adverse developmental and maternal outcomes. The database was analyzed for the prevalence of EFDT incidence and the nature and severity of adverse findings in the two species. Some manifestation of EFDT in either one or both species (rat and rabbit) was demonstrated for 282 compounds (74%), and EFDT was detected in only one species (rat or rabbit) in almost a third (31%, 118 compounds), with approximately 58% rat and 42% rabbit studies identifying an EFDT signal among the 379 compounds tested. For 24 compounds (6%), fetal malformations were observed in one species (rat or rabbit) in the absence of any EFDT in the second species. In general, growth retardation, fetal variations, and malformations were more prominent in the rat, whereas embryo-fetal death was observed more often in the rabbit. Discor

    Full Text Available Objective. The detection of paternally inherited sequences in maternal plasma, such as the SRY gene for fetal sexing or RHD for fetal blood group genotyping, is becoming part of daily routine in diagnostic laboratories. Due to the low percentage of fetal DNA, it is crucial to ensure sample stability and the efficiency of DNA extraction. We evaluated blood stability at 4°C for at least 24 hours and automated DNA extraction, for fetal sex determination in maternal plasma. Methods. A total of 158 blood samples were collected, using EDTA-K tubes, from women in their 1st trimester of pregnancy. Samples were kept at 4°C for at least 24 hours before processing. An automated DNA extraction was evaluated, and its efficiency was compared with a standard manual procedure. The SRY marker was used to quantify cfDNA by real-time PCR. Results. Although lower cfDNA amounts were obtained by automated DNA extraction (mean 107,35 GE/mL versus 259,43 GE/mL, the SRY sequence was successfully detected in all 108 samples from pregnancies with male fetuses. Conclusion. We successfully evaluated the suitability of standard blood tubes for the collection of maternal blood and assessed samples to be suitable for analysis at least 24 hours later. This would allow shipping to a central reference laboratory almost from anywhere in Europe.

    2009-08-01

    To assess normative values of the fetal atrioventricular (AV) time interval by pulse-wave Doppler methods on 5-chamber view. Fetal echocardiography exams were performed using Acuson Sequoia 512 in 140 singleton fetuses at 18 to 40 weeks of gestation with sinus rhythm and normal cardiac and extracardiac anatomy. Pulsed Doppler derived AV intervals were measured from left ventricular inflow/outflow view using transabdominal convex 3.5-6 MHz probe. The values of AV time interval ranged from 100 to 150 ms (mean 123 +/- 11.2). The AV interval was negatively correlated with the heart rhythm (page of gestation (p=0.007). However, in the same subgroup of the fetal heart rate there was no relation between AV intervals and gestational age. Therefore, the AV intervals showed only the heart rate dependence. The 95th percentiles of AV intervals according to FHR ranged from 135 to 148 ms. 1. The AV interval duration was negatively correlated with the heart rhythm. 2. Measurement of AV time interval is easy to perform and has a good reproducibility. It may be used for the fetal heart block screening in anti-Ro and anti-La positive pregnancies. 3. Normative values established in the study may help obstetricians in assessing fetal abnormalities of the AV conduction.

    This study sought to describe the association between spiritual well-being, demographic characteristics, quality of life (QOL) and depressive symptoms following spinal cord injury (SCI). We hypothesized QOL and depressed mood would both be explained by extent of spiritual well-being, and meaning-focused (M&P) spirituality would have a stronger impact than faith-focused spirituality. 210 individuals with SCI were screened as part of a randomized control trial of venlafaxine XR for major depressive disorder (MDD). 204 completed all measures: Patient Health Questionniare-9 (PHQ-9) assessed depression, the FACIT-Sp assessed spiritual well-being, the Neuro-QOL PAWB scale assessed QOL, and the PANAS assessed affect. Approximately 26% had major depression. Bivariate correlations of scores on PAWB and PANAS and FACIT-Sp showed that all four scales had strong associations with those on PAWB (p scales of the FACIT-Sp were significant predictors of QOL (β = 0.544; p scale was an independently significant predictor of likely MDD. The findings support that spirituality, as measured by the FACIT-Sp, is strongly associated with QOL and likelihood of MDD. Assessment of spirituality should be included along with more traditional psychological measurements to better inform treatment. Implications for Rehabilitation Spiritual beliefs can contribute to quality of life and may help moderate depressive symptoms that accompany chronic illness and disability, suggesting that rehabilitation professionals should address spirituality in working with their patients with spinal cord injury (SCI). While spiritual issues are often deferred to pastoral counselors during hospitalization, it is clear that addressing these is not the domain of one discipline and does not end upon inpatient discharge. In addressing spirituality, clinicians should tap the spiritual strengths present in their clients, whether meaning/peace-focused or religious, understanding that spirituality involves more

    This study explored links between narrative identity, personality traits, and well-being for 263 adolescents (age 12-21) from three New Zealand cultures: Māori, Chinese, and European. Turning-point narratives were assessed for autobiographical reasoning (causal coherence), local thematic coherence, emotional expressivity, and topic. Across cultures, older adolescents with higher causal coherence reported better well-being. Younger adolescents with higher causal coherence instead reported poorer well-being. Personal development topics were positively linked to well-being for New Zealand European adolescents only, and thematic coherence was positively linked to well-being for Māori adolescents only. Negative expressivity, neuroticism, conscientiousness, and openness were also linked to well-being. Implications of these cultural similarities and differences are considered for theories of narrative identity, personality, and adolescent well-being. © 2016 The Authors.

    2017-01-01

    Full Text Available Background One important aspect of subjective judgments about one’s well-being (i.e., subjective well-being: life satisfaction, positive affect, and negative affect is that cultural features, such as, nationality seem to shape cognitive judgments about the “the ideal life.” In this comparative study we examined differences in subjective well-being and psychological well-being between Italian and Swedish adolescents and tested if the relationship between the three constructs of subjective well-being (i.e., satisfaction with life, positive affect, and negative affect and psychological well-being was moderated by the adolescents’ nationality. Method Italian (n = 255 and Swedish (n = 277 adolescents answered to the Satisfaction with Life Scale, the Positive Affect Negative Affect Schedule, and Ryff’s Scales of Psychological Well-Being. Differences between samples were tested using a Multiple Analysis of Variance. We also conducted a multiple group analysis (Italy and Sweden using Structural Equation Modelling to investigate the relationship between all three subjective well-being constructs and psychological well-being. Results Italian adolescents scored significantly higher in satisfaction with life than Swedish adolescents. Additionally, across countries, girls scored significantly higher in negative affect than boys. In both countries, all three constructs of subjective well-being were significantly associated to adolescents’ psychological well-being. Nevertheless, while the effect of the relationship between affect and psychological well-being was almost the same across countries, life satisfaction was more strongly related to psychological well-being among Swedish adolescents. Conclusions The present study shows that there are larger variations between these two cultures in the cognitive construct of subjective well-being than in the affective construct. Accordingly, associations between the cognitive component, not the affective

    Fetal heart rate (FHR) values in the averaged format that are provided by commercial computed cardiotocography analysis systems may be unsuitable for special analysis purposes. I developed a communication software program to obtain any measured values of fetal monitors for individual analysis of computed cardiotocography. The software program was used to study the data continuity of beat-to-beat FHR values as an experiment for chaos theory and power spectrum analysis. The results indicated that the signal loss was recognized at a precision of 95%. The described method of digital communication with fetal monitors was found to be useful for individual purposes in the field of computed cardiotocography analysis.

  6. Temporary arrest of fetal movement with pancuronium bromide to enable antenatal magnetic resonance imaging of holoprosencephaly.

    1989-10-01

    The well-known ability of real-time ultrasound to detect congenital abnormalities is often limited by acoustic artifact or fetal position or both. Magnetic resonance imaging can provide superior soft tissue resolution but is vulnerable to maternal and fetal motion artifact. Described and illustrated here is a case of fetal holoprosencephaly that was not of diagnostic clarity on ultrasound. The fetus was paralyzed with an intramuscular injection of pancuronium bromide before a resonance imaging study. Successful fetal paralysis with pancuronium bromide has been reported prior to a variety of fetal interventions for the temporary arrest of fetal movement. The resonance study illustrated here was of significantly superior clarity and improved the accuracy of prognosis and management counseling. It is concluded that in selected cases where ultrasound is not of diagnostic clarity due to acoustic artifact, fetal paralysis and magnetic resonance imaging may be considered.

    Since 2007 the second-trimester fetal anomaly scan is offered to all pregnant women as part of the national prenatal screening program in the Netherlands. Dutch population-based screening programs generally have a well-described system to achieve quality assurance. Because of the absence of a uniform system to monitor the actual performance of the fetal anomaly scan in 2012, we developed a standardized image-scoring method. The aim of this study was to evaluate the scanning performance of all sonographers in the southwestern region of the Netherlands using this image-scoring method. Each sonographer was requested to set up a digital portfolio. A portfolio consists of five logbooks from five different pregnant women, each containing 25 fetal anatomical structures and six biometric measures of randomly selected fetal anomaly scans. During the study period, 425 logbooks of 85 sonographers were assessed as part of the audit process. Seventy-three out of 85 sonographers (86%) met the criteria in the primary audit, and 12 sonographers required individual hands-on training. A successful assessment was achieved for 11 sonographers in the re-audit and one sonographer ceased her contract. Moreover, 2.1% of the required images were not digitally stored and therefore could not be reviewed. Quality assessment using the image-scoring method demonstrated that most of the sonographers met the expectations of the audit process, but those who had subpar performance met the expectations after retraining. © 2017 by the American Institute of Ultrasound in Medicine.

    The overuse of online games is known to be inversely related to various indicators of well-being. This article validates the DSM-5 criteria of internet gaming disorder (IGD), and analyzes its links with five indicators of well-being: life satisfaction, loneliness, anxiety, depression, and academic performance in a French-speaking sample of 693 gamers. Exploratory and confirmatory factor analyses showed a one-factor structure of IGD criteria. The IGD scale showed satisfactory validity and reliability and was related in a consistent way with well-being measures. The IGD scale appears to be an appropriate measure to assess video game addiction and will contribute to increase the comparability of international research on video game addiction.

    There is an ongoing discussion how to assess acute mountain sickness (AMS) in real life conditions. Next to more-item scales with a cut off like the Lake Louise Self-Report (LLS), some authors suggested to use visual analog scales (VAS) to assess AMS. This study tried to contribute to this question using VAS items used for the Subjective Ratings of Drug Effects, including an additional single item for AMS. Furthermore, we investigated if instruments developed to assess psychological well-being might predict AMS assessed via LLS or VAS. 32 (19 Female) adult persons with known AMS susceptibility filled in questionnaires (Feeling Scale, Felt Arousal Scale, Activation Deactivation Check List, LLS, VAS) at a height of 3650 m above sea level. Correlation and regression analysis suggest a moderate to high relationship between the LLS score and the VAS items, including one VAS item asking for the severity of AMS, as well as psychological well-being. In conclusion, using VAS items to assess AMS can be a more precise alternative to questionnaires like LLS, for people knowledgeable with AMS. Furthermore, researchers should be aware that psychological well-being might be an important parameter influencing the assessment of AMS.

    Previous research has shown that individual differences in negative emotion differentiation may play a prominent role in well-being. Yet, many basic questions about negative emotion differentiation remain unanswered, including how it relates and overlaps with related and known dimensions of individual differences and what its possible underlying processes are. To answer these questions, in the current article we present three correlational studies that chart the nomological network of individual differences in negative emotion differentiation in terms of personality, difficulties in identifying and describing feelings, and several indicators of well-being, propose a novel paradigm to assess it in the lab, and explore relationships with a possible underlying mechanism in terms of the motivation to approach or avoid emotions. The results affirm consistent relations between negative emotion differentiation and indicators of adjustment like negative affect, self-esteem, neuroticism, depression and meta-knowledge about one's emotions, and show how it is related to the motivation to experience affective states.

    Well-being is a positively-framed, holistic assessment of health and quality of life that is associated with longevity and better health outcomes. We aimed to identify county attributes that are independently associated with a comprehensive, multi-dimensional assessment of individual well-being. We performed a cross-sectional study examining associations between 77 pre-specified county attributes and a multi-dimensional assessment of individual US residents' well-being, captured by the Gallup-Sharecare Well-Being Index. Our cohort included 338,846 survey participants, randomly sampled from 3,118 US counties or county equivalents. We identified twelve county-level factors that were independently associated with individual well-being scores. Together, these twelve factors explained 91% of the variance in individual well-being scores, and they represent four conceptually distinct categories: demographic (% black); social and economic (child poverty, education level [divorced); clinical care (% eligible women obtaining mammography, preventable hospital stays per 100,000, number of federally qualified health centers); and physical environment (% commuting by bicycle and by public transit). Twelve factors across social and economic, clinical care, and physical environmental county-level factors explained the majority of variation in resident well-being.

  17. Zika virus infection in immunocompetent pregnant mice causes fetal damage and placental pathology in the absence of fetal infection

    Zika virus (ZIKV) infection during human pregnancy may cause diverse and serious congenital defects in the developing fetus. Previous efforts to generate animal models of human ZIKV infection and clinical symptoms often involved manipulating mice to impair their Type I interferon (IFN) signaling, thereby allowing enhanced infection and vertical transmission of virus to the embryo. Here, we show that even pregnant mice competent to generate Type I IFN responses that can limit ZIKV infection nonetheless develop profound placental pathology and high frequency of fetal demise. We consistently found that maternal ZIKV exposure led to placental pathology and that ZIKV RNA levels measured in maternal, placental or embryonic tissues were not predictive of the pathological effects seen in the embryos. Placental pathology included trophoblast hyperplasia in the labyrinth, trophoblast giant cell necrosis in the junctional zone, and loss of embryonic vessels. Our findings suggest that, in this context of limited infection, placental pathology rather than embryonic/fetal viral infection may be a stronger contributor to adverse pregnancy outcomes in mice. Our finding demonstrates that in immunocompetent mice, direct viral infection of the embryo is not essential for fetal demise. Our immunologically unmanipulated pregnancy mouse model provides a consistent and easily measurable congenital abnormality readout to assess fetal outcome, and may serve as an additional model to test prophylactic and therapeutic interventions to protect the fetus during pregnancy, and for studying the mechanisms of ZIKV congenital immunopathogenesis.

    Fetal pulse oximetry is a minimally invasive, simple technique which continuously helps to reflect in utero well-being. The presence of meconium in the amniotic fluid may be a clinical sign of fetal hypoxaemia. Amnioinfusion has a beneficial effect on the incidence of meconium aspiration syndrome (MAS), and the presence of meconium below the level of the vocal cords. We studied the impact of amnioinfusion combined with fetal pulse oximetry on the incidence of meconium aspiration syndrome and operative delivery. The retrospective analysis revealed that the presence of meconium below the level of vocal cords was significantly reduced. The frequency of cesarean section is decreased, however, it did not reach statistical significance. Fetal pulse oximetry may be used in combination with amnioinfusion and cardiotocography (CTG) to reduce the risk of meconium aspiration syndrome and the number of instrumental deliveries and improve perinatal outcome.

    Background. Self-regulation is the procedure implemented by an individual striving to reach a goal and consists of two inter-related strategies: assessment and locomotion. Moreover, both subjective and psychological well-being along exercise behaviour might also play a role on adolescents academic achievement. Method. Participants were 160 Swedish high school pupils (111 boys and 49 girls) with an age mean of 17.74 (sd = 1.29). We used the Regulatory Mode Questionnaire to measure self-regulation strategies (i.e., locomotion and assessment). Well-being was measured using Ryff's Psychological Well-Being Scales short version, the Temporal Satisfaction with Life Scale, and the Positive Affect and Negative Affect Schedule. Exercise behaviour was self-reported using questions pertaining to frequency and intensity of exercise compliance. Academic achievement was operationalized through the pupils' mean value of final grades in Swedish, Mathematics, English, and Physical Education. Both correlation and regressions analyses were conducted. Results. Academic achievement was positively related to assessment, well-being, and frequent/intensive exercise behaviour. Assessment was, however, negatively related to well-being. Locomotion on the other hand was positively associated to well-being and also to exercise behaviour. Conclusions. The results suggest a dual (in)direct model to increase pupils' academic achievement and well-being-assessment being directly related to higher academic achievement, while locomotion is related to frequently exercising and well-being, which in turn, increase academic achievement.

  1. Fetal karyotype: can we always trust its result?

    Full Text Available We retrospectively investigated six cases of discrepancy between prenatal fetal karyotype and postnatal findings. In five cases, the chromosomal abnormalities initially found by CVS or amniocentesis were not confirmed by later analyses and postnatal examination. In one case, the fetal karyotype found to be normal by CVS had to be checked due to sonographic features and clinical anomalies found after birth. In most cases, the normal development on sonographic examination raised the doubt about the abnormal fetal karyotype. Discrepant findings between fetal karyotype results and sonographic findings require great caution in their interpretation and counseling of parents. Placental confined mosaicism seems to be the most frequent cause of such discrepant results. The interpretation of fetal karyotype results should always be correlated with sonographic and clinical findings.

    Full Text Available Abstract Background Arsenic exposure in pregnancy is associated with adverse pregnancy outcome and infant mortality. Knowledge of the spatial characteristics of the outcomes and their possible link to arsenic exposure are important for planning effective mitigation activities. The aim of this study was to identify spatial and spatiotemporal clustering of fetal loss and infant death, and spatial relationships between high and low clusters of fetal loss and infant death rates and high and low clusters of arsenic concentrations in tube-well water used for drinking. Methods Pregnant women from Matlab, Bangladesh, who used tube-well water for drinking while pregnant between 1991 and 2000, were included in this study. In total 29,134 pregnancies were identified. A spatial scan test was used to identify unique non-random spatial and spatiotemporal clusters of fetal loss and infant death using a retrospective spatial and spatiotemporal permutation and Poisson probability models. Results Two significant clusters of fetal loss and infant death were identified and these clusters remained stable after adjustment for covariates. One cluster of higher rates of fetal loss and infant death was in the vicinity of the Meghna River, and the other cluster of lower rates was in the center of Matlab. The average concentration of arsenic in the water differed between these clusters (319 μg/L for the high cluster and 174 μg/L for the low cluster. The spatial patterns of arsenic concentrations in tube-well water were found to be linked with the adverse pregnancy outcome clusters. In the spatiotemporal analysis, only one high fetal loss and infant death cluster was identified in the same high cluster area obtained from purely spatial analysis. However, the cluster was no longer significant after adjustment for the covariates. Conclusion The finding of this study suggests that given the geographical variation in tube-well water contamination, higher fetal loss and

    Laypeople and many social scientists assume that superior reasoning abilities lead to greater well-being. However, previous research has been inconclusive. This may be because prior investigators used operationalizations of reasoning that favored analytic as opposed to wise thinking. We assessed wisdom in terms of the degree to which people use various pragmatic schemas to deal with social conflicts. With a random sample of Americans we found that wise reasoning is associated with greater life satisfaction, less negative affect, better social relationships, less depressive rumination, more positive vs. negative words used in speech, and greater longevity. The relationship between wise reasoning and well-being held even when controlling for socio-economic factors, verbal abilities, and several personality traits. As in prior work there was no association between intelligence and well-being. Further, wise reasoning mediated age-related differences in well-being, particularly among the middle-aged and older adults. Implications for research on reasoning, well-being and aging are discussed. PMID:22866683

    Prenatal iron deficiency alters fetal developmental trajectories, which results in persistent changes in organ function. Here, we studied the effects of prenatal iron deficiency on fetal kidney and liver mitochondrial function. Pregnant Sprague-Dawley rats were fed partially or fully iron-restricted diets to induce a state of moderate or severe iron deficiency alongside iron-replete control rats. We assessed mitochondrial function via high-resolution respirometry and reactive oxygen species generation via fluorescence microscopy on gestational d 21. Hemoglobin levels were reduced in dams in the moderate (-31%) and severe groups (-54%) compared with controls, which was accompanied by 55% reductions in fetal hemoglobin levels in both moderate and severe groups versus controls. Male iron-deficient kidneys exhibited globally reduced mitochondrial content and respiration, as well as increased cytosolic superoxide and decreased NO. Female iron-deficient kidneys exhibited complex II down-regulation and increased mitochondrial oxidative stress. Male iron-deficient livers exhibited reduced complex IV respiration and increased cytosolic superoxide, whereas female liver tissues exhibited no alteration in oxidant levels or mitochondrial function. These findings indicate that prenatal iron deficiency causes changes in mitochondrial content and function as well as oxidant status in a sex- and organ-dependent manner, which may be an important mechanism that underlies the programming of cardiovascular disease.-Woodman, A.

    Full Text Available This study examined the extent to which four factors—acculturation, ethnic identity, self-esteem, and resilience—can explain the well-being of Colombian immigrants in the United States across three waves of immigration (wave 1, from 1945–1964; wave 2, from 1965–1989; and wave 3, from 1990–2008. The results indicate that of the four factors, self-esteem most correlated with and was a predictor of well-being. Participants exhibited high levels of well-being as their level of self-esteem increased. Ethnic identity negatively predicted well-being, especially for men who entered during wave 3; as the extent of their ethnic identity increased, their well-being decreased. Correspondingly, Colombians who entered as political refugees reported a lower level of well-being. This research was groundbreaking in assessing factors contributing to the well-being of Colombian immigrants and assisting in the search for appropriate scales to study this population. Although its results have to be considered with caution, the study opens doors to future research, policies, and programs regarding the mental health assessment and treatment of Colombians in the United States.

    Evidence of the short term relationship between maternal and fetal heart rates has been found in previous studies. However there is still limited knowledge about underlying mechanisms and patterns of the coupling throughout gestation. In this study, Transfer Entropy (TE) was used to quantify directed interactions between maternal and fetal heart rates at various time delays and gestational ages. Experimental results using maternal and fetal electrocardiograms showed significant coupling for 63 out of 65 fetuses, by statistically validating against surrogate pairs. Analysis of TE showed a decrease in transfer of information from fetus to the mother with gestational age, alongside the maturation of the fetus. On the other hand, maternal to fetal TE was significantly greater in mid (26–31 weeks) and late (32–41 weeks) gestation compared to early (16–25 weeks) gestation (Mann Whitney Wilcoxon (MWW) pgestation. This difference was not observed for the fetuses with smaller RMSSD, which could be associated with the quiet sleep state. Delay in the information transfer from mother to fetus significantly decreased (p = 0.03) from mid to late gestation, implying a decrease in fetal response time. These changes occur concomitant with the maturation of the fetal sensory and autonomic nervous systems with advancing gestational age. The effect of maternal respiratory rate derived from maternal ECG was also investigated and no significant relationship was found between breathing rate and TE at any lag. In conclusion, the application of TE with delays revealed detailed information on the fetal-maternal heart rate coupling strength and latency throughout gestation, which could provide novel clinical markers of fetal development and well-being.

  8. HOW SHOULD THE WELFARE OF FETAL AND NEUROLOGICALLY IMMATURE POSTNATAL ANIMALS BE PROTECTED?

    2016-01-01

    Legal protection of the welfare of prenatal animals has not previously been addressed as a discrete subject within the academic literature on animal welfare, ethics and law. This paper aims to rectify this by reviewing the protections (or absence of protections) provided for fetuses by existing legislation in various jurisdictions, and considering the extent to which legal protection of animal fetuses can be justified on animal welfare grounds. Questions related to the need to protect the welfare of neurologically immature postnatal animals are also considered. We argue that there are reasons to protect animal fetuses, both in order to protect fetuses themselves against possible suffering, and in order to protect the animals which fetuses will become against negative welfare impacts that originate prenatally. We review the science on whether fetuses can suffer, and argue that extant regulations do not fully reflect current scientific understanding. Following the precautionary principle, we further argue that regulators should consider the possibility that foetuses and neurologically immature postnatal animals may suffer due to subcortically based ‘raw basic affects’ (i.e. relatively undifferentiated experiences of discomfort suggested to be generated by neural processing at levels below the cerebral cortex). Furthermore we show that there are reasons for affording fetuses protection in order to safeguard the long-term welfare of future animals. However, it may be possible to provide such protection via rules or laws relating to the use of certain techniques and the management of pregnant animals, rather than via direct legal protection of fetuses themselves. In order to provide such protection effectively we need to know more about the relationship between maternal nutrition, stress, exercise, management and fetal health, and about the impact of the timing of a fetal insult on long-term postnatal welfare.

    The aim was to evaluate whether assisted reproductive technology (ART) affects the development of the fetal central nervous system (CNS). This study was carried out on women with singleton pregnancies, including 427 women who became pregnant by ART and 32,859 women with natural conceptions (NCs). The cavum septum pellucidum (CSP) width, transverse cerebellar diameter (TCD), cisterna magna (CM) depth, and lateral ventricle width were measured by ultrasound for 72 normal ART fetuses and 201 normal NC fetuses. The malformation rate of CNS was determined for both groups. In both groups, significant positive correlations with gestational age were found for CSP width (ART: r=0.7841, NC: r=0.7864; P0.05). The development and malformation rate of the fetal CNS is not significantly different between ART and NC fetuses, thus, ART does not affect the development of the fetal brain.

  10. Fetal neonatal hyperthyroidism: diagnostic and therapeutic approachment

    2017-01-01

    Fetal and neonatal hyperthyroidism may occur in mothers with Graves’ disease. Fetal thyrotoxicosis manifestation is observed with the transition of TSH receptor stimulating antibodies to the fetus from the 17th–20th weeks of pregnancy and with the fetal TSH receptors becoming responsive after 20 weeks. The diagnosis is confirmed by fetal tachycardia, goiter and bone age advancement in pregnancy and maternal treatment is conducted in accordance. The probability of neonatal hyperthyroidism is high in the babies of mothers that have ongoing antithyroid requirement and higher antibody levels in the last months of pregnancy. Clinical manifestation may be delayed by 7–17 days because of the antithyroid drugs taken by the mother. Neonatal hyperthyroidism symptoms can be confused with sepsis and congenital viral infections. Herein, the diagnosis and therapeutic approach are reviewed in cases of fetal neonatal hyperthyroidism. PMID:28439194

    The well-being of non-human primates in captivity is of joint concern to scientists, veterinarians, colony managers, caretakers, and researchers working with non-human primates in biomedical research. With increased regulatory, accreditation, and research focus on optimizing the use of social housing for laboratory primates, as well as the advent of techniques to assess indices of chronic stress and related measures of well-being, there is no better time to present the most current advances in the field of non-human primate behavioral management. The collective body of research presented here was inspired in part by a 2014 symposium entitled, "Chronic Hormones and Demographic Variables: Center-Wide Studies on Non-Human Primate Well-Being" held at the American Society of Primatologists' 37th Annual Meeting in Decatur, GA. By aiming to target readership with scientific and/or management oversight of captive primate behavioral management programs, this special issue provides badly-needed guidance for implementing social housing programs in a research environment and leverages collaboration across multiple facilities to address key components of behavioral management, explore refinements in how well-being can be measured, and identify the interrelationships between varying indices.

    To determine whether short time variation (STV) of fetal heart beat correlates with scalp pH measurements during labor. From 1279 deliveries, 197 women had at least one fetal scalp pH measurement. Using the CTG-Player, STVs were calculated from the electronically saved cardiotocography (CTG) traces and related to the fetal scalp pH measurements. There was no correlation between STV and fetal scalp pH measurements (r=-0.0592). Fetal STV is an important parameter with high sensitivity for antenatal fetal acidosis. This study shows that STV calculations do not correlate with fetal scalp pH measurements during labor, hence are not helpful in identifying fetal acidosis.

Combined, this interest opens the door...... to the fruitful application of well-being research to society. Research on well-being, however, is not always well integrated across the disciplines that purport to study it. In particular, there is insufficient communication between the empirical study of well-being, and its normative/conceptual study as pursued...... in philosophy. This state of affairs is lamentable, as it robs science and public policy of the expertise of philosophers, a desirable tool when evaluating empirical claims about well-being promotion. In this article, I examine the reasons for this lack of communication. In particular, I reject the view...

  17. Maternal feeding controls fetal biological clock.

    Directory of Open Access Journals (Sweden)

    Hidenobu Ohta

    Full Text Available BACKGROUND: It is widely accepted that circadian physiological rhythms of the fetus are affected by oscillators in the maternal brain that are coupled to the environmental light-dark (LD cycle. METHODOLOGY/PRINCIPAL FINDINGS: To study the link between fetal and maternal biological clocks, we investigated the effects of cycles of maternal food availability on the rhythms of Per1 gene expression in the fetal suprachiasmatic nucleus (SCN and liver using a transgenic rat model whose tissues express luciferase in vitro. Although the maternal SCN remained phase-locked to the LD cycle, maternal restricted feeding phase-advanced the fetal SCN and liver by 5 and 7 hours respectively within the 22-day pregnancy. CONCLUSIONS/SIGNIFICANCE: Our results demonstrate that maternal feeding entrains the fetal SCN and liver independently of both the maternal SCN and the LD cycle. This indicates that maternal-feeding signals can be more influential for the fetal SCN and particular organ oscillators than hormonal signals controlled by the maternal SCN, suggesting the importance of a regular maternal feeding schedule for appropriate fetal molecular clockwork during pregnancy.

    The aim of this study was to explore the association between the cerebro-umbilical ratio measured at 35-37 weeks and intrapartum fetal compromise. This retrospective cross sectional study was conducted at the Mater Mothers' Hospital in Brisbane, Australia. Maternal demographics and fetal Doppler indices at 35-37 weeks gestation for 1381 women were correlated with intrapartum and neonatal outcomes. Babies born by caesarean section or instrumental delivery for fetal compromise had the lowest median cerebro-umbilical ratio 1.60 (IQR 1.22-2.08) compared to all other delivery groups (vaginal delivery, emergency delivery for failure to progress, emergency caesarean section for other reasons or elective caesarean section). The percentage of infants with a cerebro-umbilical ratio cerebro-umbilical ratio between the 10th-90th centile and 9.6% of infants with a cerebro-umbilical ratio > 90th centile required delivery for the same indication (p cerebro-umbilical ratio was associated with an increased risk of emergency delivery for fetal compromise, OR 2.03 (95% CI 1.41-2.92), p cerebro-umbilical ratio measured at 35-37 weeks is associated with a greater risk of intrapartum compromise. This is a relatively simple technique which could be used to risk stratify women in diverse healthcare settings. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2012-01-01

    Gross domestic product has long been the chief measure of national success. But there's been a lot of talk lately about changing that, from economists and world leaders alike. GDP is under siege for three main reasons. First, it is flawed even on its own terms: It misses lots of economic activity (unpaid household work, for example) and, as a single-number representation of vast, complex systems, is inevitably skewed. Second, it fails to account for economic and environmental sustainability. And third, readily available alternative measures may reflect well-being far better, by taking into account factors such as educational achievement, health, and life expectancy. HBR's Justin Fox surveys historical and current views on how to assess national progress, from Jeremy Bentham to Robert Kennedy to Nicolas Sarkozy. He also looks at where we may be headed. The biggest success so far in the campaign to supplant or at least supplement GDP, he finds, is the UN's Human Development Index-on which the United States has never claimed the top spot.

    2017-11-01

    Fetal ECG monitoring is a useful method to assess the fetus health and detect abnormal conditions. In this paper we propose an approach to extract fetal ECG from abdomen and chest signals using independent component analysis based on the joint approximate diagonalization of eigenmatrices approach. The JADE approach avoids redundancy, what reduces matrix dimension and computational costs. Signals were filtered with a high pass filter to eliminate low frequency noise. Several levels of decomposition were tested until the fetal ECG was recognized in one of the separated sources output. The proposed method shows fast and good performance.

    Full Text Available Fetal dural sinus thrombosis is a rare finding. Most cases have been terminated without long-term follow-ups. Recently some reports have indicated the potentially favorable evolution of fetal dural sinus thrombosis. Most of the fetuses showing symptoms have been delivered with normal neurologic outcome. We report a case of fetal dural sinus thrombosis. Serial ultrasound and magnetic resonance images (MRI showed the shrinkage of the thrombosis which indicated good prognosis. No physical or neurological abnormality was observed at 8-months follow-up. Conservative treatment is appropriate to prenatally diagnosed dural sinus thrombosis with favorable prognostic factors. Serial MRI or ultrasound should be taken every 1-2 months to monitor the thrombosis development and fetal well-beings.

    Full Text Available Well-being is a positively-framed, holistic assessment of health and quality of life that is associated with longevity and better health outcomes. We aimed to identify county attributes that are independently associated with a comprehensive, multi-dimensional assessment of individual well-being.We performed a cross-sectional study examining associations between 77 pre-specified county attributes and a multi-dimensional assessment of individual US residents' well-being, captured by the Gallup-Sharecare Well-Being Index. Our cohort included 338,846 survey participants, randomly sampled from 3,118 US counties or county equivalents.We identified twelve county-level factors that were independently associated with individual well-being scores. Together, these twelve factors explained 91% of the variance in individual well-being scores, and they represent four conceptually distinct categories: demographic (% black; social and economic (child poverty, education level [well-being.

    2013-01-01

    AMNIOCENTESIS FOR FETAL LUNG MATURITY HAS HISTORICALLY BEEN PERFORMED FOR MANY REASONS: uterine and placental complications, maternal comorbidities, fetal issues, and even obstetric problems. Even though the risks associated with third trimester amniocentesis are extremely low, complications have been documented, including preterm labor, placental abruptions, intrauterine rupture, maternal sepsis, fetal heart rate abnormalities, and fetal-maternal hemorrhage. This review presents the types of tests for fetal lung maturity, presents the indications and tests utilized, and discusses recommendations for when amniocentesis for fetal lung maturity may be appropriate.

    Recent developments in research and mobile health enable a quantitative idiographic approach in health research. The present study investigates the potential of an electronic diary crowdsourcing study in the Netherlands for (1) large-scale automated self-assessment for individual-based health promotion and (2) enabling research at both the between-persons and within-persons level. To illustrate the latter, we examined between-persons and within-persons associations between somatic symptoms and quality of life. A website provided the general Dutch population access to a 30-day (3 times a day) diary study assessing 43 items related to health and well-being, which gave participants personalized feedback. Associations between somatic symptoms and quality of life were examined with a linear mixed model. A total of 629 participants completed 28,430 assessments, with a mean (SD) of 45 (32) assessments per participant. Most participants (n = 517 [82%]) were women and 531 (84%) had high education. Almost 40% of the participants (n = 247) completed enough assessments (t = 68) to generate personalized feedback including temporal dynamics between well-being, health behavior, and emotions. Substantial between-person variability was found in the within-person association between somatic symptoms and quality of life. We successfully built an application for automated diary assessments and personalized feedback. The application was used by a sample of mainly highly educated women, which suggests that the potential of our intensive diary assessment method for large-scale health promotion is limited. However, a rich data set was collected that allows for group-level and idiographic analyses that can shed light on etiological processes and may contribute to the development of empirical-based health promotion solutions.

    Summary Maternal metabolism provides essential nutrients to enable embryonic development. However, both mother and embryo produce reactive metabolites that can damage DNA. Here we discover how the embryo is protected from these genotoxins. Pregnant mice lacking Aldh2, a key enzyme that detoxifies reactive aldehydes, cannot support the development of embryos lacking the Fanconi anemia DNA repair pathway gene Fanca. Remarkably, transferring Aldh2−/−Fanca−/− embryos into wild-type mothers suppresses developmental defects and rescues embryonic lethality. These rescued neonates have severely depleted hematopoietic stem and progenitor cells, indicating that despite intact maternal aldehyde catabolism, fetal Aldh2 is essential for hematopoiesis. Hence, maternal and fetal aldehyde detoxification protects the developing embryo from DNA damage. Failure of this genome preservation mechanism might explain why birth defects and bone marrow failure occur in Fanconi anemia, and may have implications for fetal well-being in the many women in Southeast Asia that are genetically deficient in ALDH2.

    Dötsch, Jörg; Plank, Christian; Amann, Kerstin

    2012-04-01

    Results from large epidemiological studies suggest a clear relation between low birth weight and adverse renal outcome evident as early as during childhood. Such adverse outcomes may include glomerular disease, hypertension, and renal failure and contribute to a phenomenon called fetal programming. Other factors potentially leading to an adverse renal outcome following fetal programming are maternal diabetes mellitus, smoking, salt overload, and use of glucocorticoids during pregnancy. However, clinical data on the latter are scarce. Here, we discuss potential underlying mechanisms of fetal programming, including reduced nephron number via diminished nephrogenesis and other renal (e.g., via the intrarenal renin-angiotensin-aldosterone system) and non-renal (e.g., changes in endothelial function) alterations. It appears likely that the outcomes of fetal programming may be influenced or modified postnatally, for example, by the amount of nutrients given at critical times.

    2018-03-01

    This essay examines core contributions of a model of psychological well-being that has had widespread scientific impact. It drew on distant formulations to identify new dimensions and measures for assessing what it means to be well. Key themes among the more than 750 studies using the model are sketched, followed by reflections about why there has been so much interest in this eudaimonic approach to well-being. A final section looks to the future, proposing new directions to illuminate the forces that work against the realization of human potential as well as those that nurture human flourishing and self-realization.

    4D ultrasound imaging of the fetal heart relies on reconstructions from B-mode images. In the presence of fetal motion, current approaches suffer from artifacts, which are unrecoverable for single sweeps. We propose to use many sweeps and exploit the resulting redundancy to automatically recover from motion by reconstructing a 4D image which is consistent in phase, space, and time. An interactive visualization framework to view animated ultrasound slices from 4D reconstructions on arbitrary planes was developed using a magnetically tracked mock probe. We first quantified the performance of 10 4D reconstruction formulations on simulated data. Reconstructions of 14 in vivo sequences by a baseline, the current state-of-the-art, and the proposed approach were then visually ranked with respect to temporal quality on orthogonal views. Rankings from 5 observers showed that the proposed 4D reconstruction approach significantly improves temporal image quality in comparison with the baseline. The 4D reconstructions of the baseline and the proposed methods were then inspected interactively for accessibility to clinically important views and rated for their clinical usefulness by an ultrasound specialist in obstetrics and gynecology. The reconstructions by the proposed method were rated as 'very useful' in 71% and were statistically significantly more useful than the baseline reconstructions. Multi-sweep fetal heart ultrasound acquisitions in combination with consistent 4D image reconstruction improves quality as well as clinical usefulness of the resulting 4D images in the presence of fetal motion.

    Use of fetal tissue for cytogenetic analysis in cases of second- and third-trimester fetal demise frequently results in unacceptably high failure rates. We reviewed our ongoing use of amniocentesis prior to uterine evacuation to determine if this provided a better source of cells for cytogenetic analysis. We compared cytogenetic results using fetal tissues obtained following uterine evacuation to our ongoing use of amniotic fluid cell obtained by transabdominal amniocentesis prior to uterine evacuation from 2003 to 2008. In 49 of the 63 cases evaluated by fetal tissue biopsies performed after uterine evacuation, a karyotypic analysis was obtained (77.8%). Among the 38 cases evaluated by amniocentesis, an amniotic fluid sample and fetal cytogenetic results were obtained in all 38 (100%) cases. Our findings indicate that amniocentesis is a more reliable source of cytogenetic information than fetal tissue in cases of second- and third-trimester fetal demise.

    There is increasing recognition that physician wellness is critical; it not only benefits the provider, but also influences quality and patient care outcomes. Despite this, resident physicians suffer from a high rate of burnout and personal distress. Individuals with higher emotional intelligence (EI) are thought to perceive, process, and regulate emotions more effectively, which can lead to enhanced well-being and less emotional disturbance. This study sought to understand the relationship between EI and wellness among surgical residents. Residents in a single general surgery residency program were surveyed on a voluntary basis. Emotional intelligence was measured using the Trait Emotional Intelligence Questionnaire-Short Form. Resident wellness was assessed with the Dupuy Psychological General Well-Being Index, Maslach Burnout Inventory, and Beck Depression Inventory-Short Form. Emotional intelligence and wellness parameters were correlated using Pearson coefficients. Multivariate analysis was performed to identify factors predictive of well-being. Seventy-three residents participated in the survey (response rate 63%). Emotional intelligence scores correlated positively with psychological well-being (r = 0.74; p emotional exhaustion (r = -0.69; p emotional exhaustion (β = -0.63; p Emotional intelligence is a strong predictor of resident well-being. Prospectively measuring EI can identify those who are most likely to thrive in surgical residency. Interventions to increase EI can be effective at optimizing the wellness of residents.

    Reduced birth weight predisposes to cardiovascular diseases in later life. We examined in fetal sheep at 0.76 (n = 18) and 0.87 (n = 17) gestation whether spontaneously occurring variations in fetal weight affect maturation of autonomic control of cardiovascular function. Fetal weights at both gestational ages were grouped statistically in low (LW) and normal weights (NW) (P fetal sheep not constituting a major malnutritive condition. Mean fetal blood pressure (FBP) of all fetuses was negatively correlated to fetal weight at 0.76 but not 0.87 gestation (P fetal heart rate depended on fetal weight (P fetal weight within the normal weight span is accompanied by a different trajectory of development of sympathetic blood pressure and vagal heart rate control. This may contribute to the development of elevated blood pressure in later life. Examination of the underlying mechanisms and consequences may contribute to the understanding of programming of cardiovascular diseases.

    Prenatal mercury exposure has been related to reductions in anthropometry at birth. Levels of mercury have been reported as being relatively elevated in the Spanish population. To investigate the relation between prenatal exposure to mercury and fetal growth. Study subjects were pregnant women and their newborns (n:1867) participating in a population-based birth cohort study set up in four Spanish regions from the INMA Project. Biparietal diameter (BPD), femur length (FL), abdominal circumference (AC), and estimated fetal weight (EFW) were measured by ultrasounds at 12, 20, and 34 weeks of gestation. Size at and growth between these points were assessed by standard deviation (SD) scores adjusted for constitutional characteristics. Total mercury (T-Hg) was determined in cord blood. Associations were investigated by linear regression models, adjusted by sociodemographic, environmental, nutritional - including four seafood groups - and lifestyle-related variables in each sub-cohort. Final estimates were obtained using meta-analysis. Effect modification by sex, seafood intake and polychlorinated biphenyl (PCB) congener 153 concentration was assessed. Geometric mean of cord blood T-Hg was 8.2μg/L. All the estimates of the association between prenatal Hg and growth from 0 to 12 weeks showed reductions in SD-scores, which were only statistically significant for BPD. A doubling of cord blood T-Hg was associated with a 0.58% reduction in size of BPD at week 12 (95% confidence interval -CI-: - 1.10, - 0.07). Size at week 34 showed estimates suggestive of a small reduction in EFW, i.e., a doubling of T-Hg levels was associated with a reduction of 0.38% (95% CI: - 0.91, 0.15). An interaction between PCB153 and T-Hg was found, with statistically significant negative associations of T-Hg with AC and EFW in late pregnancy among participants with PCB153 below the median. Exposure to mercury during pregnancy was associated with early reductions in BPD. Moreover, an antagonism with

The information to assess air pollutant exposure during pregnancy is based on outdoor measurement of air pollutants (nitrogen dioxide [NO2], volatile organic compounds [VOC], ozone, particulate matter [PM10, PM2,5 ] and of their composition [polycyclic aromatic hydrocarbons]); measurement of indoor and personal exposure (VOC and NO2); urinary measurement of a biological marker of hydrocarbon exposure (1-hydroxypyrene); and data gathered by questionnaires and geographic information systems. These data allow individual air pollutant exposure indexes to be developed, which can then be used to analyze the possible effects of exposure on fetal development and child health. This protocol and the type of study allow an approximation to individual air pollutant exposure to be obtained. Finally, the large number of participants (N = 4,000), as well as their geographic and social diversity, increases the study's potential.

    It is of interest to estimate the influence of the environment in a specific work place area on the performance and well-being of people. Investigations have been carried out for the cabin environment of an airplane and for class rooms. Acoustics is only one issue of a variety of environmental factors, therefore the combined impact of temperature, humidity, air quality, lighting, vibration, etc. on human perception is the subject of psychophysical research. Methods for the objective assessment of subjective impressions have been developed for applications in acoustics for a long time, e.g., for concert hall acoustics, noise evaluation, and sound design. The methodology relies on questionnaires, measurement of acoustic parameters, ear-related signal processing and analysis, and on correlation of the physical input with subjective output. Methodology and results are presented from measurements of noise and vibration, temperature and humidity in aircraft simulators, and of reverberation, coloring, and lighting in a primary school, and of the environmental perception.

    Full Text Available Fetal tachyarrhythmia is unfeigned in most cases and occurs in about 1–3% of the total number of pregnancies. Most of it's kinds are ectopic intraatrial reductions. FA is usually diagnosed during the routine, starting from 18 weeks of gestation, ultrasound assessment of the fetal heart rate. Approximately 10% of fetuses with rhythm disorders are at high risk of sudden death. Supraventricular tachycardia and atrial fibrillation are the most common causes of sudden death, the same is observed for bradyarrhythmias: manifest sinus bradycardia (hypoxic genesis and expressed AV-blockade. The examination of all fetuses with arrhythmia was strongly recommended in cases of intrauterine cardiac arrest or death of the fetus in families. Arrhythmias which have been revealed during scheduled prenatal examination of the fetuses are in need of expert echocardiography assessment to determine the extent of possible pre- and postnatal risk of sudden death and the paril of arrhythmogenic cardiomyopathy formation. In case of identified life-threatening arrhythmia in fetus the pharmacological therapy, which greatly affects the favorable outcome is strongly recommended. It should be based on hemodynamic of pregnant and aimed to prevent the development of decompensation or arrhythmogenic cardiomyopathy.

    Conclusion: This small series demonstrate that an antenatal diagnosis of fetal stroke with intraventricular hemorrhage Grades III and IV or with brain parenchymal involvement appears to be associated with poor neurologic outcome. Due to the significant neonatal neurologic impairment and potential medicolegal implications of antepartum fetal ICH, it follows that obstetricians and sonographers should be familiar with predisposing factors and typical diagnostic imaging findings of rare in utero ICH events.

    Although magnetic resonance imaging (MRI) of the fetus is considered an established adjunct to fetal ultrasound, stacks of images alone cannot provide an overall impression of the fetus. The present study evaluates the use of thick-slab T2-weighted MR images to obtain a three-dimensional impression of the fetus using MRI. A thick-slab T2-weighted sequence was added to the routine protocol in 100 fetal MRIs obtained for various indications (19th to 37th gestational weeks) on a 1.5 T magnet using a five-element phased-array surface coil. Slice thickness adapted to fetal size and uterine geometry varied between 25 and 50 mm, as did the field of view (250-350 mm). Acquisition of one image took less than 1 s. The pictorial essay shows that these images visualize fetal anatomy in a more comprehensive way than is possible with a series of 3-4 mm thick slices. These thick-slab images facilitate the assessment of the whole fetus, fetal proportions, surface structures, and extremities. Fetal pathology may be captured in one image. Thick-slab T2-weighted images provide additional information that cannot be gathered from a series of images and are considered a valuable adjunct to conventional 2D MR images

    Research shows that active support provision is associated with greater well-being for spouses of individuals with chronic conditions. However, not all instances of support may be equally beneficial for spouses' well-being. The theory of communal responsiveness suggests that because spouses' well-being is interdependent, spouses benefit most from providing support when they believe their support increases their partner's happiness and is appreciated. Two studies tested this hypothesis. Study 1 was a 7-day ecological momentary assessment (EMA) study of 73 spouses of persons with dementia (74%) and other conditions. In Study 1, spouses self-reported active help, perceptions of how happy the help made the partner and how much the help improved the partner's well-being, and spouses' positive and negative affect at EMA time points. Study 2 was a 7-day daily assessment study of 43 spouses of persons with chronic pain in which spouses reported their emotional support provision, perceived partner appreciation, and their own physical symptoms. Study 1 showed that active help was associated with more positive affect for spouses when they perceived the help increased their partner's happiness and improved their partner's well-being. Study 2 showed that emotional support provision was associated with fewer spouse reported physical symptoms when perceptions of partner appreciation were high. Results suggest that interventions for spouses of individuals with chronic conditions take into account spouses' perceptions of their partners' positive emotional responses. Highlighting the positive consequences of helping may increase spouses' well-being. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    In the last decade the newest technologies, fetal magnetic resonance imaging (MRI) and 3D ultrasound, have given an insight into the minute structures of the fetal brain. However, without knowledge of the basic developmental processes the imaging is futile. Knowledge of fetal neuroanatomy corresponding to the gestational week is necessary in order to recognize pathological structures. Furthermore, a modern neuroradiologist should be acquainted with the three steps in the formation of the cerebral cortex: proliferation, migration and differentiation of neurons in order to be in a position to suspect that there is a pathology and start recognizing and discovering the abnormalities. The fetal MRI has become an important complementary method to ultrasound especially in cortical malformations when confirmation of the prenatal diagnosis is needed and additional pathologies need to be diagnosed. In this manner these two methods help in parental counseling and treatment planning. (orig.) [German] Dank neuer Technologien (z. B. fetale MRT, 3-D-Sonographie) ist es moeglich, kleinste Hirnstrukturen darzustellen. Ohne Kenntnisse der grundlegenden Entwicklungsprozesse des Gehirns waere die Bildgebung jedoch sinnlos. Um pathologische Veraenderungen zu erkennen, ist es notwendig, den Stand der fetalen Neuroanatomie in der entsprechenden Schwangerschaftswoche zu kennen. Heutzutage sollte sich ein Neuroradiologe mit den 3 Schritten der kortikalen Entwicklung - Proliferation, Migration und Differenzierung der Neuronen - vertraut machen. Nur dann wird er in der Lage sein, pathologische Veraenderungen in Betracht zu ziehen, bzw. diese zu erkennen. Die fetale MRT ist besonders wichtig, ergaenzend zur zerebralen Sonographie, zur Diagnosebestaetigung bei kortikalen Veraenderungen und Nachweis weiterer Pathologien. In dieser Kombination ermoeglichen diese Methoden eine adaequate Beratung der Eltern und Planung der Behandlung. (orig.)

It is an important indicator of maternal and perinatal health of a given population. This study was undertaken to study the maternal and fetal factors associated with intrauterine fetal death. Aim and Objective- This was an Analytical study aimed to evaluate and understand the prevalence, socio-epidemiological and etiological factors of IUFD methodology should not be mixed with aims and objectives MATERIALS AND METHODS The study was carried out at March 2017 to June 2017 (4 months study which was conducted at Dr. S. N. Medical College, Jodhpur, Rajasthan. The details were entered in a preformed proforma. IUD is defined as fetal death beyond 20 weeks of gestation and/or birth weight >500g. The details of complaints at admission, obstetrics history, menstrual history, examination findings, per vaginal examination findings, mode and method of delivery and fetal outcomes and investigation reports were recorded. RESULTS A total of 227 intrauterine fetal deaths were reported amongst 6264 deliveries conducted during the study period. The incidence rate of intrauterine fetal death was 36/1000 live births. 192 (84.56% deliveries were unbooked and unsupervised and 133 (58.59% belonged to rural population and 126 (55.5% were preterm and 221 (97.55% were singleton pregnancy.

    This study examines the relationships between internalized stigma, psychological well-being, and subjective well-being in a sample of people with mental illness. We conducted a cross-sectional study with 213 outpatients from the Spanish public social care network. The results showed that (a) internalized stigma was significantly negatively correlated with psychological well-being and subjective well-being (affect balance and life satisfaction) (all correlations are significant with at least pstigma on affect balance and life satisfaction was mediated by psychological well-being. The component of internalized stigma most consistently associated with both types of well-being was alienation (life satisfaction: B=-0.35, p=0.001; affect balance: B=-0.38, p=0.001). These findings should be confirmed in future longitudinal or experimental research. On the basis of these results we recommend that interventions to combat self-stigma aim to reduce feelings of alienation and improve self-acceptance and other aspects of positive psychological functioning.

    We assessed and tracked perceptions of well-being among employees of member companies of HealthPartners, a nonprofit health care provider and health insurance company in Bloomington, Minnesota. The objective of our study was to determine the concordance between self-reported life satisfaction and a construct of subjective well-being that comprised 6 elements of well-being: emotional and mental health, social and interpersonal status, financial status, career status, physical health, and community support. We analyzed responses of 23,268 employees (of 37,982 invitees) from 6 HealthPartners companies who completed a health assessment in 2011. We compared respondents' answers to the question, "How satisfied are you with your life?" with their indicators of well-being where "high life satisfaction" was defined as a rating of 9 or 10 on a scale of 0 (lowest) to 10 (highest) and "high level of well-being" was defined as a rating of 9 or 10 for 5 or 6 of the 6 indicators of well-being. We found a correlation between self-reported life satisfaction and the number of well-being elements scored as high (9 or 10) (r = 0.62, P life satisfaction, only 34.7% of those indicating high life satisfaction reported high overall well-being. The correlation between self-reported life satisfaction and our well-being measure was strong, and members who met our criterion of high overall well-being were likely to report high life satisfaction. However, many respondents who reported high life satisfaction did not meet our criterion for high overall well-being, which suggests that either they adapted to negative life circumstances or that our well-being measure did not identify their sources of life satisfaction.

    2006-01-01

    Because of the superior tissue contrast, high spatial resolution, and multiplanar capabilities, fetal magnetic resonance imaging (MRI) can depict fetal brain pathologies with high accuracy. Pathological fetal brain development may result from malformations or acquired conditions. Differentiation of these etiologies is important with respect to managing the actual pregnancy or counseling future pregnancies. As a widened ventricular system is a common hallmark of both maldevelopment and acquired conditions, it may cause problems in the differential diagnosis. Fetal MRI can provide detailed morphological information, which allows refinement of the diagnosis of ventricular enlargement in a large number of cases. Systematic work-up of morphological details that may be recognized on MR images provides an approach for achieving a correct diagnosis in cases of ventricle enlargement. (orig.) [de

    The purpose of this study was to investigate the psychometric properties of the modified Thai Spiritual Well-Being Scale in patients with advanced cancer. This cross-sectional study was employed to investigate psychometric properties. Some 196 participants from three tertiary hospitals in Bangkok and suburban Thailand were asked to complete a Personal Information Questionnaire (PIQ), The Memorial Symptom Assessment Scale (MSAS), and the Spiritual Well-Being Scale (SWBS). Validity was determined by known-group, concurrent, and constructs validity. Reliability was estimated using internal consistency by Cronbach's α coefficients. Three factors were extracted: so-called existential well-being, religious well-being, and peacefulness accounted for 71.44% of total variance. The Cronbach's α coefficients for total SWB, EWB, RWB, and peacefulness were 0.96, 0.94, and 0.93, respectively. These findings indicate that the Thai SWBS is a valid and reliable instrument, and it presented one more factor than the original version.

    To explore suitable scales to assess psychological status of pregnant women whose fetuses have grave deformities, a face-to-face interview guided by the Triage Assessment System (TAS) was conducted. Also, a questionnaire of the Impact of Event Scale-Revised (IES-R) was obtained in 44 pregnant women diagnosed with a fetal deformity. Percentages and non-parametric Spearman correlations were used to analyse the scores of the two scales. The total score of TAS ranged from 3 to 26, with a mean of 9.93; and the total score of IES-R ranged from 5 to 63, with a mean of 40.36. The total score and the two subscales of each scale were significantly correlated (P < 0.05). The TAS subscale of emotion and IES-R subscale of intrusion were not significantly correlated, with r = 0.24 (P = 0.11). Combined use of TAS and IES-R can make up for each other's deficiencies and guide the clinician to make individual interventions during screening and treatment. © 2014 Wiley Publishing Asia Pty Ltd.

    We present the task of predicting individual well-being, as measured by a life satisfaction scale, through the language people use on social media. Well-being, which encompasses much more than emotion and mood, is linked with good mental and physical health. The ability to quickly and accurately assess it can supplement multi-million dollar national surveys as well as promote whole body health. Through crowd-sourced ratings of tweets and Facebook status updates, we create message-level predictive models for multiple components of well-being. However, well-being is ultimately attributed to people, so we perform an additional evaluation at the user-level, finding that a multi-level cascaded model, using both message-level predictions and userlevel features, performs best and outperforms popular lexicon-based happiness models. Finally, we suggest that analyses of language go beyond prediction by identifying the language that characterizes well-being.

    Full Text Available Background/Aim. Although lamellar bodies have been the center of interest over the last years, the published results of fetal pulmonary maturity determination according to their concentration in amniotic fluid are controversial. The aim of this study was to determine the significance of lamellar bodies, as well as the ratio lecithin/sphingomyelin (L/S in amniotic fluid for the assessment of fetal pulmonary maturity. Methods. This prospective 2-year study included 102 female examinees, ranging from 17 to 44 years of age, in whom lamellar bodies concentrations in amniotic fluid were determined to check the efficacy of the applied therapy for obtaining arteficial fetal pulmonary maturity. The shake test was applied as a comparative test for determining a quantitative L/S ratio. To determine a fetus maturity and development stage we followed up biparietal diameter, abdominal circumference, femure length, ponderal index at birth and body mass. Results. Out of a total of 102 amniocenteses within a period from 26th to 40th gestation week only 70 results were considered due to 32 unknown neonatal outcomes. Biparietal diameter was 224-362 mm, femur length 56 - 78 mm, ponderal index 1.22-2.84, fetus body mass 1300- 4 350 g. There was found a significant relation between gestation age and lamellar bodies concentration (R = 0.396398, p < 0.01, as well as between gestation age and the ratio L/S (R = 0.691297, p < 0.01. Also, there was a significant correlation of lamellar bodies concentration to the ratio L/S determined (R = 0.493609, p < 0.01. Conclusion. Determination of lamellar bodies concentration values is a reliable method to confirm fetal pulmonary maturity.

    Ultrasound biometry is an important clinical tool for the identification, monitoring, and management of fetal growth restriction and development of macrosomia. This is even truer in populations in which perinatal morbidity and mortality rates are high, which is a reason that much effort is put onto making the technique available everywhere, including low-income societies. Until recently, however, commonly used reference ranges were based on single populations largely from industrialized countries. Thus, the World Health Organization prioritized the establishment of fetal growth charts for international use. New fetal growth charts for common fetal measurements and estimated fetal weight were based on a longitudinal study of 1387 low-risk pregnant women from 10 countries (Argentina, Brazil, Democratic Republic of Congo, Denmark, Egypt, France, Germany, India, Norway, and Thailand) that provided 8203 sets of ultrasound measurements. The participants were characterized by median age 28 years, 58% nulliparous, normal body mass index, with no socioeconomic or nutritional constraints (median caloric intake, 1840 calories/day), and had the ability to attend the ultrasound sessions, thus essentially representing urban populations. Median gestational age at birth was 39 weeks, and birthweight was 3300 g, both with significant differences among countries. Quantile regression was used to establish the fetal growth charts, which also made it possible to demonstrate a number of features of fetal growth that previously were not well appreciated or unknown: (1) There was an asymmetric distribution of estimated fetal weight in the population. During early second trimester, the distribution was wider among fetuses 50th percentile. (2) Although fetal sex, maternal factors (height, weight, age, and parity), and country had significant influence on fetal weight (1-4.5% each), their effect was graded across the percentiles. For example, the positive effect of maternal height on fetal

    Full Text Available Intrahepatic cholestasis of pregnancy (ICP has important fetal implications. There is increased risk for poor fetal outcomes, including preterm delivery, meconium staining of amniotic fluid, respiratory distress, fetal distress and demise.One hundred and one women diagnosed with ICP between January 2005 and March 2009 at San Francisco General Hospital were included in this study. Single predictor logistic regression models were used to assess the associations of maternal clinical and biochemical predictors with fetal complications. Clinical predictors analyzed included age, race/ethnicity, gravidity, parity, history of liver or biliary disease, history of ICP in previous pregnancies, and induction. Biochemical predictors analyzed included serum aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, total bilirubin, direct bilirubin, albumin, total protein, and total bile acids (TBA.The prevalence of ICP was 1.9%. Most were Latina (90%. Labor was induced in the majority (87% and most were delivered by normal spontaneous vaginal delivery (84%. Fetal complications occurred in 33% of the deliveries, with respiratory distress accounting for the majority of complications. There were no statistically significant clinical or biochemical predictors associated with an increased risk of fetal complications. Elevated TBA had little association with fetal complications until reaching greater than 100 µmoL/L, with 3 out of 5 having reported complications. ICP in previous pregnancies was associated with decreased risk of fetal complications (OR 0.21, p = 0.046. There were no cases of late term fetal demise.Maternal clinical and laboratory features, including elevated TBA, did not appear to be substantial predictors of fetal complications in ICP.

    Full Text Available Objective. Chemokines exert different inflammatory responses which can potentially be related to certain fetal chromosomal abnormalities. The aim of the study was to determine the concentration of selected chemokines in plasma and amniotic fluid of women with fetal Down syndrome. Method. Out of 171 amniocentesis, we had 7 patients with confirmed fetal Down syndrome (15th–18th weeks of gestation. For the purpose of our control, we chose 14 women without confirmed chromosomal aberration. To assess the concentration of chemokines in the blood plasma and amniotic fluid, we used a protein macroarray, which allows the simultaneous determination of 40 chemokines per sample. Results. We showed significant decrease in the concentration of 4 chemokines, HCC-4, IL-28A, IL-31, and MCP-2, and increase in the concentration of CXCL7 (NAP-2 in plasma of women with fetal Down syndrome. Furthermore, we showed decrease in concentration of 3 chemokines, ITAC, MCP-3, MIF, and increase in concentration of 4 chemokines, IP-10, MPIF-1, CXCL7, and 6Ckine, in amniotic fluid of women with fetal Down syndrome. Conclusion. On the basis of our findings, our hypothesis is that the chemokines may play role in the pathogenesis of Down syndrome. Defining their potential as biochemical markers of Down syndrome requires further investigation on larger group of patients.

    Full Text Available Imbalance in the metabolites levels which can potentially be related to certain fetal chromosomal abnormalities can stimulate mother’s immune response to produce autoantibodies directed against proteins. The aim of the study was to determine the concentration of 9000 autoantibodies in maternal plasma to detect fetal Down syndrome. Method. We performed 190 amniocenteses and found 10 patients with confirmed fetal Down syndrome (15th–18th weeks of gestation. For the purpose of our control we chose 11 women without confirmed chromosomal aberration. To assess the expression of autoantibodies in the blood plasma, we used a protein microarray, which allows for simultaneous determination of 9000 proteins per sample. Results. We revealed 213 statistically significant autoantibodies, whose expression decreased or increased in the study group with fetal Down syndrome. The second step was to create a classifier of Down syndrome pregnancy, which includes 14 antibodies. The predictive value of the classifier (specificity and sensitivity is 100%, classification errors, 0%, cross-validation errors, 0%. Conclusion. Our findings suggest that the autoantibodies may play a role in the pathophysiology of Down syndrome pregnancy. Defining their potential as biochemical markers of Down syndrome pregnancy requires further investigation on larger group of patients.

    Full Text Available Pregnant rats were fed a high fat diet (HFD for the first (HF1, second (HF2, third (HF3 or all three weeks (HFG of gestation. Maintenance on a HFD during specific periods of gestation was hypothesized to alter fetal glycemia, insulinemia, induce insulin resistance; and alter fetal plasma and hepatic fatty acid (FA profiles. At day 20 of gestation, fetal plasma and hepatic FA profiles were determined by gas chromatography; body weight, fasting glycemia, insulinemia and the Homeostasis Model Assessment (HOMA-insulin resistance were also determined. HF3 fetuses were heaviest concomitant with elevated glycemia and insulin resistance (p < 0.05. HFG fetuses had elevated plasma linoleic (18:2 n-6 and arachidonic (20:4 n-6 acid proportions (p < 0.05. In the liver, HF3 fetuses displayed elevated linoleic, eicosatrienoic (20:3 n-6 and arachidonic acid proportions (p < 0.05. HFG fetuses had reduced hepatic docosatrienoic acid (22:5 n-3 proportions (p < 0.05. High fat maintenance during the final week of fetal life enhances hepatic omega-6 FA profiles in fetuses concomitant with hyperglycemia and insulin resistance thereby presenting a metabolically compromised phenotype.

    Full Text Available Background & aim: Maternal-fetal attachment has an important effect on mother's identity as well as maternal and fetal health. Moreover, this concept is considered as a crucial issue for the improvement of children emotional development. Regarding the Islamic recommendations on maternal-fetal attachment and its correlation with maternal affection, this study was conducted to review the importance of maternal-fetal attachment according to the Islamic recommendations. Methods: This review was conducted on the religious texts, which covered the subject of interest and were published within 2000-2017. Various databases including Medline, PubMed, Google, IranMedex, SID, and Magiran as well as the websites of Muslim authorities (i.e., the section responding to religious questions were searched. The searching was carried out using keywords as: “Islamic religious teachings”, “pregnant women and Fatwa of the Islamic jurists”, and “aspects of maternal fetal attachment in Islam”. Results: According to the results of the reviewed texts, the mutual readiness of mother and fetus leads to the improvement of their affection. The maternal factors affecting the maternal-neonatal attachment included personality traits, marriage, selection of partner, post-marriage issues, pregnancy, as well as physical and psychological characteristics. There were also some effective factors on the newborn’s innate readiness for the development of attachment, such as fetal appearance, family and social support, maternal nutrition during pregnancy, and neonatal mood. Conclusion: According to the Holy Quran versus and hadiths, maternal-fetal attachment and its promotion are affected by both maternal and fetal factors. Moreover, following the factors affecting attachment will lead to their role functioning. Therefore, it is intensively recommended to incorporate a glance of Islamic instruction into the pregnancy education to improve the maternal-fetal attachment.

    The aim of this study was to determine the effect of gestational diabetes mellitus (GDM) on fetal insulin resistance or β-cell function in Chinese pregnant women with GDM. Maternal fasting blood and venous cord blood samples (reflecting fetal condition) were collected in 65 well-controlled Chinese GDM mothers (only given dietary intervention) and 83 control subjects. The insulin, glucose and proinsulin concentrations of both maternal and cord blood samples were measured, and the homeostasis model assessment of insulin resistance (HOMA-IR) and the proinsulin-to-insulin ratios (an indicator of fetal β-cell function) were calculated in maternal and cord blood respectively. Both maternal and fetal levels of insulin, proinsulin and HOMA-IR but not proinsulin-to-insulin ratios were significantly higher in the GDM group than in the control group (maternal insulin, 24.8 vs. 15.4 µU/mL, P = 0.004, proinsulin, 23.3 vs. 16.2 pmol/L, P = 0.005, and HOMA-IR, 5.5 vs. 3.5, P = 0.041, respectively; fetal: insulin, 15.1 vs. 7.9 µU/mL, Pinsulin ratios was significantly correlated to maternal HOMA-IR (r = 0.307, P = 0.019), in the pregnant women with GDM. Fetal insulin resistance was higher in Chinese pregnant women with GDM than control subjects, and correlated with maternal insulin resistance.
