RESUMEN

CONTEXT: Excess glucocorticoids impact fetal health. Maternal glucocorticoids peak in early morning. Fetoplacental 11ß-hydroxysteroid dehydrogenase type 2 (11ß-HSD2) inactivates cortisol to cortisone, protecting the fetus from high glucocorticoids. However, time-specific alterations of human fetoplacental 11ß-HSD2 have not been studied. OBJECTIVE: We hypothesized that fetoplacental 11ß-HSD2 activity shows time-specific alteration and acute affective or anxiety disorders impact fetoplacental 11ß-HSD2 activity. METHODS: In this observational study we investigated 78 pregnant European women undergoing amniocentesis (15.9 ± 0.9 weeks of gestation). Amniotic fluid was collected (8:00 to 16:30 hours) for analysis of fetoplacental 11ß-HSD2 activity, using cortisol (F):cortisone (E) ratio in amniotic fluid, E/(E + F). Fetoplacental 11ß-HSD2 rhythm and association with "acute affective or anxiety disorder" (patients with at least one of: a major depressive episode, specific phobia, panic disorder, generalized anxiety disorder, mixed anxiety and depressive disorder) and "acute anxiety disorder" (one of: panic disorder, generalized anxiety disorder, mixed anxiety, depressive disorder), assessed using Mini International Neuropsychiatric Interview, were investigated. RESULTS: Activity of 11ß-HSD2 correlated with time of amniocentesis, peaking in the morning (r = -0.398; P < 0.001) and increased with acute affective or anxiety disorder (mean [M] = 0.70 vs M = 0.74; P = 0.037) and acute anxiety disorder (M = 0.70 vs M = 0.75; P = 0.016). These associations remained significant when controlling for confounders. 11ß-HSD2 activity correlated negatively with pre-pregnancy body mass index (r = -0.225; P = 0.047). CONCLUSION: Our study indicates a time-specific alteration of fetoplacental 11ß-HSD2 activity with peaking levels in the morning, demonstrating a mechanism of fetal protection from the morning maternal glucocorticoid surge.

RESUMEN

BACKGROUND: Expanded carrier screening (ECS) utilizes high-throughput next-generation sequencing to evaluate an individual's carrier status for multiple conditions. Combined malonic and methylmalonic aciduria (CMAMMA) due to ACSF3 deficiency is a rare inherited disease included in such screening panels. Some cases have been reported with metabolic symptoms in childhood yet other cases describe a benign clinical course, suggesting the clinical phenotype is not well defined. METHODS/CASE REPORT: Clinical and laboratory findings during the prenatal period were obtained retrospectively from medical records. RESULTS: A 37-year-old nulliparous woman and her partner were each identified as carriers of ACSF3 variants and presented at 9 weeks gestation for prenatal genetic consultation. The couple received extensive genetic counseling and proceeded with chorionic villus sampling at 11 weeks gestation. Subsequent analysis confirmed that the fetus inherited both parental ACSF variants. The couple was devastated by the results and after reviewing options of pregnancy continuation and termination, they decided to terminate the pregnancy. Following this decision, the patient was diagnosed with acute stress disorder. CONCLUSION: This case highlights how expanded carrier screening adds complexity to reproductive decision-making. Stronger guidelines and additional research are needed to direct and evaluate the timing, composition, and implementation of ECS panels.

RESUMEN

OBJECTIVE: To evaluate the impact of introduction of noninvasive prenatal testing (NIPT) on the uptake of invasive testing in pregnancies complicated by fetal central nervous system (CNS) anomalies. METHODS: Retrospective review of all singleton pregnancies complicated by fetal CNS anomalies seen at a single tertiary center between 2010 and 2017. Cases who had undergone invasive testing or NIPT prior to the diagnosis of the CNS anomaly were excluded. Cases were segregated according to whether they were seen prior to introduction of NIPT (group A, 2010-2013) or thereafter (group B, 2014-2017). We examined the rate of invasive and noninvasive genetic testing in each group. RESULTS: We retrieved 500 cases: 308 (62%) were isolated CNS anomalies, and 192 (38%) had additional structural anomalies. In the total cohort, 165 women (33%) underwent expectant management with no further prenatal genetic testing, 166 (33%) had invasive testing, 52 (10%) had NIPT, and 117 pregnancies (23%) were terminated without further prenatal investigations. The introduction of NIPT significantly decreased the number of pregnancies having no testing (44% group A vs 22% in group B, p < .0001), particularly in the group presenting with isolated ventriculomegaly, but did not affect the uptake of invasive testing (34% vs 32%, respectively; p = .61). NIPT would have missed 4% of pathogenic copy number variants (CNVs) in the group of cases with isolated brain anomalies and 11% of CNVs in cases with complex anomalies. CONCLUSIONS: Uptake of invasive prenatal testing in fetuses with brain anomalies was not affected by NIPT. However, the incidence of no genetic testing was significantly reduced. NIPT was a suboptimal testing strategy in this population as it missed a significant number of subchromosomal genetic anomalies.

RESUMEN

BACKGROUND: In recent years, determination of personalized risk for fetal chromosomal anomalies emerged as an important component of prenatal genetic counseling. Women in whom fetal risk for chromosomal aberrations is elevated are offered further testing. The aim of this study was to identify factors that may influence the decision to refuse invasive prenatal testing aimed at determination of fetal karyotype in a group of patients at increased risk of trisomy 21. METHODS: The analysis included 177 patients with singleton pregnancy, whose personalized risk score for trisomy 21 calculated on the basis of the combined test exceeded 1:300. Diagnostic amniocentesis was performed in 125 patients from this subset, since the remaining 52 women declined invasive prenatal testing. The following factors were analyzed as potential determinants of the decision to refuse amniocentesis: maternal age (≥35 years), gravidity, number of miscarriages in previous pregnancies, educational status, marital status, indications to prenatal testing, gestational age at the time of prenatal testing, personalized risk score for fetal chromosomal aberrations and nuchal translucency (NT) value. RESULTS: A statistically significant relationship was found between the decision to refuse amniocentesis and the number of previous miscarriages, maternal educational level, NT values and personalized risk score for fetal chromosomal aberrations. Multivariate logistic regression analysis identified primary maternal education and history of more than two miscarriages as independent significant predictors of declining amniocentesis. Women with personalized risk scores for trisomy 21 greater than 1:100 opted out of invasive prenatal diagnosis significantly less often than the remaining participants. CONCLUSION: In conclusion, the key role of high quality and accuracy of non-invasive diagnostic tests conducted in the first trimester should be emphasized as personalized risk score for fetal chromosomal aberrations determined based on their results is pivotal for further management of pregnancy. Equally important is to provide the patients with an accurate and comprehensible information about potential benefits and risks of invasive testing.

RESUMEN

Our study aimed to identify the knowledge, attitude, and factors associated with uptake of amniocentesis test amongst pregnant women of advanced maternal age (35+ years old). A cross-sectional survey was performed on 481 participants in 2016. Women with higher educational attainment, higher income level, having a baby with congenital defects, and women with better knowledge and/or attitude about amniocentesis test were more likely to accept the test. Our study suggested the importance of counseling for women and more time should be given for them to absorb information before they make their decision to uptake the amniocentesis test.

RESUMEN

Funding policy and medico-legal climate are part of physicians' reality and might permeate clinical decisions. This study evaluates the influence of maternal age and government funding on obstetrician/gynecologist recommendation for invasive prenatal testing (i.e. amniocentesis) for Down syndrome (DS), and its association with the physician's assessment of the risk of liability for medical malpractice unless they recommend amniocentesis. Israeli physicians (N = 171) completed a questionnaire and provided amniocentesis recommendations for women at 18 weeks gestation with normal preliminary screening results, identical except aged 28 and 37. Amniocentesis recommendations were reversed for the younger ('yes' regardless of testing results: 6.4%; 'no' regardless of testing results: 31.6%) versus older woman ('yes' regardless of testing results: 40.9%; 'no' regardless of testing results: 7.0%; χ2 = 71.55, p < .01). About half of the physicians endorsed different recommendations per scenario; of these, 65.6% recommended amniocentesis regardless of testing results for the 37-year-old woman. Physicians routinely performing amniocentesis and those advocating for amniocentesis for all women ≥ age 35 were approximately twice as likely to vary their recommendations per scenario. Physicians who perceived risk of liability for malpractice as large were nearly one-and-a-half times more likely to vary recommendations. The results indicate physicians' recommendations are influenced by maternal age, though age is already incorporated in prenatal DS risk evaluations. The physician's assessment of the risk that they will be sued unless they recommend amniocentesis may contribute to this spurious influence.

RESUMEN

INTRODUCTION: Nowadays, an important decision for pregnant women is whether to undergo prenatal testing for aneuploidies and which tests to uptake. We investigate the factors influencing women's choices between non-invasive prenatal testing (NIPT) and invasive prenatal tests in pregnancies with elevated a priori risk of fetal aneuploidies. METHODOLOGY: This is a mixed-method study. We used medical data (1st Jan 2015-31st Dec 2015) about women participating in further testing at Fetomaternal Medical Center at Helsinki University Hospital and employed Chi-square tests and ANOVA to compare the groups of women choosing different methods. Multinomial logistic regressions revealed the significant clinical factors influencing women's choice. We explored the underlying values, beliefs, attitudes and other psychosocial factors that affect women's choice by interviewing women with the Theory of Planned Behavior framework. The semi-structured interview data were processed by thematic analysis. RESULTS: Statistical data indicated that gestational age and counseling day were strong factors influencing women's choice. Interview data revealed that women's values and moral principles on pregnancy and childbirth chiefly determined the choices. Behavioral beliefs (e.g. safety and accuracy) and perceived choice control (e.g. easiness, rapidness and convenience) were also important and the major trade-offs happened between these constructs. DISCUSSION: Values are the determinants of women's choice. Service availability and convenience are strong factors. Medical risk status in this choice context is not highly influential. Choice aids can be developed by helping women to identify their leading values in prenatal testing and by providing lists of value-matching test options and attributes.

RESUMEN

Objective: To evaluate the effect of supportive information on anxiety levels in women awaiting amniocentesis results. Material and Method: Women underwent amniocentesis were randomized into two groups according to whether they did (group A) or did not (group B) receive supportive information. Anxiety levels were measured using the Spielberger State-Trait Anxiety Inventory at four time points, (1) after amniocentesis, (2) before phoning for test result appointment confirmation, (3) after phoning, during which supportive information was given to group A, and (4) before receiving the test results. Semistructured interviews were conducted after the last anxiety measurement. Results: There were no significant differences in the state anxiety scores between the two groups after amniocentesis and before phoning to confirm that the amniocentesis results were available. The state anxiety scores after telephoning and before receiving the test results in group A were significantly lower than those in group B (36.69 vs. 42.50, p<0.001, and 39.16 vs. 42.82, p<0.05, respectively). We identified three stages of psychological distress, uncertainty of fetal safety, uncertainty of the test results, and hopefulness concerning the test results. Women in group B experienced only the two early stages of distress, whereas after receiving supportive information, the psychological state of women in group A further progressed to the hopefulness concerning the test result Conclusion: Supportive information could alleviate the anxiety level of women awaiting amniocentesis results. Providing appropriate supportive information for each psychological stage should be considered for women underwent amniocentesis.

RESUMEN

OBJECTIVE: To evaluate the benefit of aromatic therapy using menthol for decrease pain perception during amniocentesis. MATERIAL AND METHOD: A prospective randomized study was conducted to compare pain level between groups ofpregnant women who underwent amniocentesis with and without aromatic therapy using menthol. Visual analogue scale (VAS) was usedfor pain assessment. The participants were askedfor their anticipated pain and anxiety level and level ofpain before and immediately after the procedure. RESULTS: Three hundred seventeen pregnant women were recruited into the present study, 158 in the menthol group and 159 in the non-menthol group. Mean VAS score of the post-procedure pain and anxiety did not differ significantly between the two groups. Mean VAS score of the anticipated pain influenced the mean VAS score of the pre-procedure anxiety and post-procedure pain and anxiety irrespective of the group. Mean VAS score of the pre-procedure anxiety and post-procedure pain and anxiety increased about 0.3 cm for each 1 cm of increasing mean VAS score of anticipated pain. CONCLUSION: Aromatic therapy using menthol was not significantly effective in reducing pain and anxiety during second trimester genetic amniocentesis.

RESUMEN

OBJECTIVE: Assessing the effects of maternal anxiety on the markers and results of quadruple screening and on maternal anxiety after receiving positive results. METHODS: This prospective cohort study evaluated 1,595 pregnant women referred for prenatal visits. Maternal state/trait anxiety levels were measured, then quadruple screening was performed by measuring serum α-fetoprotein (AFP), ß-human chorionic gonadotropin, inhibin A, and unconjugated estriol (UE3). After receiving the results, the state/trait anxiety was remeasured. Amniocentesis was performed for screening-positive mothers. RESULTS: High prescreening maternal anxiety was associated with lower rates of elevated AFP (OR, 0.27; 95% CI, 0.1-0.74) and elevated inhibin A (OR, 0.38; 95% CI, 0.15-0.98). High maternal anxiety was associated with higher rates of decreased UE3 (OR, 1.8; 95% CI, 1.06-3.08). There were no significant associations between prescreening maternal anxiety and the final screening or amniocentesis results. Among the screening-positive mothers, those who had high state/trait anxiety before screening had higher anxiety scores after receiving positive results compared to those with low prescreening anxiety levels (52.9 ± 10.8 vs. 43.7 ± 10.3). CONCLUSION: High prescreening maternal anxiety is associated with lower rates of elevated AFP and inhibin A and higher rates of decreased UE3. However, maternal anxiety does not affect the final screening or amniocentesis result. High maternal state/trait anxiety before screening is associated with significantly higher maternal anxiety after the receipt of positive results.

RESUMEN

One factor women consider when deciding whether to pursue amniocentesis is the risk of miscarriage. People use mechanisms like anchoring, or the prior belief regarding the magnitude of risk, as a frame of reference for new information. This study aimed to determine a woman's perception of miscarriage risk associated with amniocentesis before and after genetic counseling and to determine what factors anchor a woman's perception of miscarriage risk. One hundred thirteen women being seen for prenatal genetic counseling and possible amniocentesis at six Houston clinics participated in the two-part anonymous survey. While most women (56.7 %) perceived the risk as low or average pre-counseling and indicated the numeric risk of amniocentesis as <1 %, significantly more patients (73 %) correctly identified the numeric risk as <1 % post-counseling (p < 0.0001). However, the majority of patients' qualitative risk perception did not change after the genetic counseling session (60 %). Those who changed their feeling about the risk after counseling showed a decreased perception of the risk (p < 0.0001). Participants who elected amniocentesis had a significantly lower perception of the risk (p = 0.017) whereas those who declined amniocentesis were more likely to view the risk as high (p = 0.004). The only two anchoring factors that had an effect were having a friend or relative with a personal or family history of a genetic disorder (p = 0.001) and having a child already (p = 0.038); both were associated with a lower risk perception. The lack of significant factors may reflect the uniqueness of each patient's risk assessment framework and reinforces the importance of genetic counseling to elucidate individual concerns, particularly as non-invasive prenatal testing becomes more widely available and further complicates the prenatal testing landscape.

RESUMEN

OBJECTIVE: The maternal autonomic nervous system (ANS) has received little attention in the investigation of biological mechanisms linking prenatal stress to fetal cortisol (F) excess. In vitro, norepinephrine and epinephrine inhibit placental 11ß-hydroxysteroid dehydrogenase type 2 (11ß-HSD2), which protects the fetus from F overexposure by inactivating it to cortisone (E). Here, we investigated the acute ANS stress response to an amniocentesis and its association with amniotic fluid F, E, and E/(E + F) as a marker of fetoplacental 11ß-HSD2 activity. METHODS: An aliquot of amniotic fluid was obtained from 34 healthy, second-trimester pregnant women undergoing amniocentesis. Repeated assessment of mood states served to examine the psychological stress response to amniocentesis. Saliva samples were collected to measure stress-induced changes in salivary α-amylase concentrations in response to amniocentesis. Cardiac parameters were measured continuously. RESULTS: Undergoing amniocentesis induced significant psychological and autonomic alterations. Low-frequency (LF)/high-frequency (HF) baseline, suggested to reflect sympathovagal balance, was negatively correlated with amniotic E/(E + F) (r=-0.53, p = .002) and positively with F (r = 0.62, p < .001). In contrast, a stronger acute LF/HF response was positively associated with E/(E + F) (r = 0.44, p = .012) and negatively with F (r=-0.40, p = .025). CONCLUSIONS: These findings suggest that the maternal ANS is involved in the regulation of the fetoplacental barrier to stress. Allostatic processes may have been initiated to counterbalance acute stress effects. In contrast, higher LF/HF baseline values, possibly indicative of chronic stress exposure, may have inhibited 11ß-HSD2 activity in the fetoplacental unit. These results parallel animal findings of up-regulated placental 11ß-HSD2 in response to acute stress but impairment under chronic stress.

RESUMEN

BACKGROUND: Risk for foetal Down syndrome (DS) increases as maternal age increases. Non-invasive screening (maternal serum triple test) for DS is routinely offered to pregnant women to provide risk estimates and suggest invasive amniocentesis for definitive pre-natal diagnosis to high-risk women. OBJECTIVE: We examined women's decision process with regard to pre-natal screening, and specifically, the degree to which they take into account triple serum screening results when considering whether or not to undergo amniocentesis. DESIGN: Semi-structured phone interviews were conducted to assess recall of DS screening results, understanding of risk estimates and their effect on women's decision whether to undergo amniocentesis. The study included 60 pregnant Israeli women (half younger than 35 and half advanced maternal age - AMA), with normal DS screening results and no known ultrasound abnormalities. RESULTS: Age appeared to determine the decision process. The vast majority of AMA women had amniocentesis, many of them before receiving their DS screening results. Most AMA participants knew that their risk estimate was 'normal', but still considered themselves at high risk due to their age. Procedure-related risk (miscarriage) and other factors only had a minor effect on their decision. A minority of younger women had amniocentesis. Younger women mentioned procedure-related risk and having normal screening results as the main factors affecting their decision not to have amniocentesis. CONCLUSION: Age 35 is an anchor for the pre-determination regarding performing or avoiding amniocentesis. AMA women mention 'age' as their main reason to have amniocentesis and considered it an independent risk factor.

RESUMEN

BACKGROUND: Decision making is integral to genetic counselling and the premise is that autonomous decisions emerge if patients are provided with information in a non-directive manner. The pivotal activity in antenatal diagnosis counselling with at-risk pregnant women is decision making regarding invasive procedures. This process is not well understood in multicultural settings. OBJECTIVE: This study examined multicultural genetic counselling interactions with women of advanced maternal age (AMA). It aimed to investigate the participants' orientation towards the amniocentesis decision. DESIGN: Data were collected during 14 video-recorded consultations between six genetic counsellors and 14 women of AMA in a genetic counselling clinic in South Africa. The design was qualitative and conversation analysis was used for analysis. RESULTS: Analysis revealed that counsellors used several strategies to facilitate discussions and decision making. However, the invitation to make a decision regarding amniocentesis was not perceived as being neutral. Both the counsellors and the women appeared to treat the offer as one which should be accepted. This resulted in a paradox, as strategies intended to allow neutral discussion seem to achieve the opposite. It is suggested that these results may be linked to the local health-care setting. CONCLUSION: The results suggest that the understanding of decision-making processes and enhancing autonomy may require a more detailed investigation into psychosocial, political and historical factors in the local health-care setting. Models of practice as well as the training of genetic counsellors need to be sensitive to these influences. A closer examination of interactional variables may yield new and relevant insights for the profession.

RESUMEN

OBJECTIVES: As there are currently no specific measures of anxiety due to prenatal diagnostic procedures, the aim of the study was to develop and validate a new measure called the Prenatal Diagnostic Procedure Anxiety Scale (PDPAS). METHODS: Seventy-four pregnant women scheduled for amniocentesis and ultrasound completed the PDPAS, the State-Trait Anxiety Inventory, the Edinburgh Postnatal Depression Scale, and the Perceived Stress Scale before undergoing the diagnostic procedure. Reliability, concurrent validity, factor structure, scale sensitivity, and specificity were analyzed. Differences between amniocentesis and ultrasound groups in the PDPAS score were analyzed with a t-test. RESULTS: The final scale comprised 11 items and two subscales measuring 'fear of procedure' and 'fear of abnormal result'. Concurrent validity analysis showed that the PDPAS is an independent measure of anxiety. At a cut-off score of >11, sensitivity was 75.0% and specificity was 72.01% with moderate accuracy. Fear of procedure was higher in the amniocentesis group, whereas fear of abnormal result was equally present in both amniocentesis and ultrasound groups. CONCLUSION: The PDPAS has good internal consistency and concurrent validity with satisfactory psychometric characteristics. As a short measure of situation-specific anxiety, it can be used as a screening tool in prenatal clinical settings.

RESUMEN

Decisions to undergo invasive prenatal diagnostic procedures can be anxiety provoking. Individuals receive information about these procedures in one of three modalities: written text, audio (verbal description), or video. We examined whether modality influences emotional responses and testing decisions, and whether trait anxiety, a disposition linked with heightened sensitivity to threatening information, moderates these effects. New Zealand adults (N = 176) completed a trait anxiety measure before random allocation to view a text, audio, or video message about amniocentesis and chorionic villus sampling. Participants completed measures of child related worry, anticipated emotional distress, anticipated coping efficacy, perceived likelihood of miscarriage, and testing interest. High-anxious individuals reported greater distress and lower coping efficacy in response to the video message compared to the audio message. They also reported greater miscarriage likelihood in response to the video message compared to the text message. These findings suggest that use of video, assumed to be most informative for educating patients, could induce greater distress about prenatal testing in individuals prone to anxiety.

RESUMEN

As medicine has evolved over the last century, medical genetics has grown from nonexistence to one of the most visible aspects of how we understand and treat disease. This increased role of genetics within medicine will only increase in the coming years, and its role in reproductive medicine will be significant. Genetics has emerged as a primary focus of research with translational applications within reproductive medicine. The aim of this article is to outline the applications of genetics currently available, and how these technologies can provide a positive impact on patient care.

RESUMEN

OBJECTIVE: Little is known about the effect of social support on the reactivity of the hypothalamic-pituitary-adrenal (HPA) axis during pregnancy. Moreover, when investigating the HPA axis most studies do not consider the activity of 11ß-hydroxysteroid dehydrogenase type 2 (11ß-HSD2), an enzyme within the salivary glands that inactivates cortisol to cortisone. This study explores the association between perceived emotional support and the maternal psychobiological stress response to a standardized naturalistic stressor by assessing maternal mood and the reactivity of salivary cortisol (SalF), salivary cortisone (SalE), and the SalE/(E+F) ratio as a marker of 11ß-HSD2 activity. METHODS: Repeated saliva samples and measures of maternal mood were obtained from 34 healthy second trimester pregnant women undergoing amniocentesis which served as a psychological stressor. The pregnant women additionally responded to a questionnaire of perceived emotional support and provided sociodemographic (e.g., maternal educational degree) and pregnancy-specific data (e.g., planned versus unplanned pregnancy). RESULTS: Perceived emotional support neither showed a significant effect on mood nor on the SalF or SalE response to stress. However, a moderately strong positive association was found between perceived emotional support and SalE/(E+F) (r=.49). Additionally, the final regression analysis revealed a significant negative relationship between educational degree, planned/unplanned pregnancy and SalE/(E+F). CONCLUSION: Findings suggest a higher metabolization of cortisol to cortisone in pregnant women with higher emotional support. In contrast, higher maternal education and unplanned pregnancy appear to be associated with decreased salivary 11ß-HSD2 activity. The current study emphasizes the importance of taking the activity of 11ß-HSD2 into account when examining SalF.
