Benchmark dataset of the effect of grain size on strength in the single-phase FCC CrCoNi medium entropy alloy.

This data article presents the microstructural data as well as the mechanical properties of the CrCoNi medium-entropy alloy (MEA). The data presented in this article are related to the research article entitled "Analysis of strengthening due to grain boundaries and annealing twin boundaries in the CrCoNi medium-entropy alloy", see Ref. Schneider et al., 2019. This article can be referred to for the analysis and interpretation of the data, as well as their comparison to other datasets in literature. Microstructural data available in the present paper are backscattered electron micrographs for sixteen different grain sizes. Also available are pdf reports of grain size analysis (annealing twin boundaries were neglected) and crystallite sizes (including annealing twin boundaries) as well as data describing the number of annealing twin boundaries per grain (n), corresponding Taylor factors (M) and average annealing twin thicknesses (t). Additionally, raw data of stress-strain curves at five different temperatures [77 K, 293 K, 473 K, 673 K and 873 K] are given for all sixteen grain sizes, which may be used for further research, e.g. data mining, machine learning and other analytical methods. Mechanical data such as yield stresses (σ 0.2% ), Hall-Petch parameters (σ 0 and k y ) and critical boundary strengths (τ c ) are provided along with a 1D discrete dislocation dynamics (1-D DDD) simulation results concerning the different boundary strengths.

The influence of maternal vulnerability and parenting stress on chronic pain in adolescents in a general population sample: the TRAILS study.

Investigating possible psychosocial predictors of unexplained chronic pain in adolescents is crucial in understanding its development and prevention. A general population sample of adolescents (n = 2230) from the TRAILS cohort study was investigated longitudinally to assess the influence of maternal vulnerability, in terms of anxiety, depression and stress, and parenting stress at age 10-12 years, on the presence of chronic pain at age 12-15 years. Of these adolescents, 269 (12.9%) reported experiencing chronic pain, of which 77% reported severe chronic pain and 22% reported multiple chronic pain. Maternal anxiety, maternal stress and higher levels of parenting stress were related to chronic pain at a later age. Subgroup analyses showed similar results for adolescents with severe chronic pain. Mediation analyses indicated that parenting stress mediates the effect between maternal anxiety, or stress, and chronic pain. The findings suggest that interventions to diminish maternal feelings of anxiety and stress, while in turn adjusting maternal behaviour, may prevent the development of chronic pain in adolescence.

Low negative affect prior to treatment is associated with a decreased chance of live birth from a first IVF cycle.

BACKGROUND: Psychological variables, such as anxiety and depression, may have a negative impact on IVF outcomes, but the evidence remains inconclusive. Previous studies have usually measured a single psychological parameter with clinical pregnancy as the outcome. The objective of the current study was to determine whether pretreatment or procedural psychological variables in women undergoing a first IVF cycle affect the chance of achieving a live birth from that cycle. METHODS: Between February 2002 and February 2004, 391 women with an indication for IVF were recruited at two University Medical Centres in The Netherlands. Pretreatment anxiety and depression were measured with the Hospital Anxiety and Depression Scale. The Daily Record Keeping Chart was used to measure negative and positive affect before treatment and daily during ovarian stimulation. Multiple stepwise forward logistic regression analysis was performed with term live birth as the dependent variable. RESULTS: Regression analysis showed that women who expressed less negative affect at baseline were less likely to achieve live birth (P = 0.03). After one IVF cycle, women who received a standard IVF strategy were more likely to reach live birth delivery than those who received a mild IVF strategy (P = 0.002). A male/female indication for IVF was associated with a higher chance of achieving term live birth than a female only indication (P = 0.03). Age, duration of infertility or type of infertility were not independent predictors of live birth. CONCLUSIONS: The relationship between psychological parameters and IVF success rates is more complex than commonly believed. The expression of negative emotions before starting IVF might not be always detrimental for outcomes.

The psychological impact of IVF failure after two or more cycles of IVF with a mild versus standard treatment strategy.

BACKGROUND: Failure of IVF treatment after a number of cycles can be devastating for couples. Although mild IVF strategies reduce the psychological burden of treatment, failure may cause feelings of regret that a more aggressive approach, including the transfer of two embryos, was not employed. In this study, the impact of treatment failure after two or more cycles on stress was studied, following treatment with a mild versus a standard treatment strategy. METHODS: Randomized controlled two-centre trial (ISRCTN35766970). Women were randomized to undergo mild ovarian stimulation (including GnRH antagonist co-treatment) and single embryo transfer (n = 197) or standard GnRH agonist long-protocol ovarian stimulation with double embryo transfer (n = 194). Participants completed the Hospital Anxiety and Depression Scale prior to commencing treatment and 1 week after the outcome of their final treatment cycle was known. Data from women who underwent two or more IVF cycles were subject to analysis (n = 253). RESULTS: Women who experienced treatment failure after standard IVF treatment presented more symptoms of depression 1 week after treatment termination compared with women who had undergone mild IVF: adjusted mean (+/-95% confidence interval) = 10.2 (+/-2.3) versus 5.4 (+/-1.8), respectively, P = 0.01. CONCLUSIONS: Failure of IVF treatment after a mild treatment strategy may result in fewer short-term symptoms of depression as compared to failure after a standard treatment strategy. These findings may further encourage the application of mild IVF treatment strategies in clinical practice.

A prospective study on parental coping 4 months after termination of pregnancy for fetal anomalies.

OBJECTIVE: To identify short-term factors influencing psychological outcome of termination of pregnancy for fetal anomaly, in order to define those patients most vulnerable to psychopathology. STUDY DESIGN: A prospective cohort of 217 women and 169 men completed standardized questionnaires 4 months after termination. Psychological adjustment was measured by the Inventory of Complicated Grief (ICG), the Impact of Event Scale (IES), the Edinburgh Postnatal Depression Scale (EPDS), and the Symptom Checklist-90 (SCL-90). RESULTS: Women and men showed high levels of posttraumatic stress (PTS) symptoms (44 and 22%, respectively) and symptoms of depression (28 and 16%, respectively). Determinants of adverse psychological outcome were the following: high level of doubt in the decision period, inadequate partner support, low self-efficacy, lower parental age, being religious, and advanced gestational age. Whether the condition was Down syndrome or another disability was irrelevant to the outcome. Termination did not have an important effect on future reproductive intentions. Only 2% of women and less than 1% of men regretted the decision to terminate. CONCLUSION: Termination of pregnancy (TOP) for fetal anomaly affects parents deeply. Four months after termination a considerable part still suffers from posttraumatic stress symptoms and depressive feelings. Patients who are at high risk could benefit from intensified support.

The psychological impact of mild ovarian stimulation combined with single embryo transfer compared with conventional IVF.

BACKGROUND: The objective of this study was to assess the psychological implications of mild ovarian stimulation combined with single embryo transfer (SET) during a first IVF cycle. METHODS: We conducted a randomized controlled two-centre trial. Three hundred and ninety-one couples were randomized to undergo either mild ovarian stimulation with GnRH antagonist co-treatment and SET (n=199) or conventional GnRH agonist long protocol ovarian stimulation with double embryo transfer (DET) (n=192). Women completed the Hospital Anxiety and Depression Scale, the Hopkins Symptom Checklist and the Subjective Sleep Quality Scale at baseline, on the first day of ovarian stimulation and following embryo transfer. Affect was assessed daily with the Daily Record Keeping Chart from the first day of ovarian stimulation until the day treatment outcome became known. RESULTS: The conventional IVF group experienced elevated levels of physical and depressive symptoms during pituitary downregulation. At oocyte retrieval, this group experienced more positive affect and less negative affect than the mild IVF group. In the conventional IVF group, cycle cancellation was associated with less positive and more negative affect. CONCLUSIONS: During the first IVF treatment cycle, mild ovarian stimulation and SET does not lead to more psychological complaints than conventional IVF.

Long-term psychological consequences of pregnancy termination for fetal abnormality: a cross-sectional study.

OBJECTIVE: We examined women's long-term psychological well-being after termination of pregnancy (TOP) for fetal anomaly in order to identify risk factors for psychological morbidity. METHODS: A cross-sectional study was performed in 254 women, 2 to 7 years after TOP for fetal anomaly before 24 weeks of gestation. We used standardised questionnaires to investigate grief, posttraumatic symptoms, and psychological and somatic complaints. RESULTS: Women generally adapted well to grief. However, a substantial number of the participants (17.3%) showed pathological scores for posttraumatic stress. Low-educated women and women who had experienced little support from their partners had the most unfavourable psychological outcome. Advanced gestational age at TOP was associated with higher levels of grief, and posttraumatic stress symptoms and long-term psychological morbidity was rare in TOP before 14 completed weeks of gestation. Higher levels of grief and doubt were found if the fetal anomaly was presumably compatible with life. CONCLUSION: Termination of pregnancy for fetal anomaly is associated with long-lasting consequences for a substantial number of women. Clinically relevant determinants are gestational age, perceived partner support, and educational level.

Effectiveness of a psychosocial counselling intervention for first-time IVF couples: a randomized controlled trial.

BACKGROUND: The objective of this study was to evaluate a psychosocial counselling intervention for first-time IVF couples. In this article the results on women's distress are presented. METHODS: Two hundred sixty-five couples admitted to an IVF treatment programme at the Erasmus MC were asked to participate in this study. Eighty-four couples agreed and were randomized according to a computer-generated random-numbers table into either a routine-care control group or an intervention group. The intervention consisted of three sessions with a social worker trained in Experiential Psychosocial Therapy: one before, one during and one after the first IVF cycle. Distress was measured daily during treatment by the Daily Record Keeping Chart. Depression and anxiety were measured before and after treatment by the Hospital Anxiety and Depression Scale. RESULTS: No significant group differences were found. CONCLUSIONS: The results of this study do not support the implementation of our counselling intervention for all first-time IVF couples. The low response rate suggests that there is little perceived need for psychosocial counselling among couples during a first IVF treatment cycle.

Child development and quality of parenting in lesbian families: no psychosocial indications for a-priori withholding of infertility treatment. A systematic review.

Among fertility centres, much discussion focuses on whether to withhold infertility treatment from special patient groups (lesbians, prospective single parent(s), prospective parent(s) of relatively advanced age, or with severe diseases) because it is assumed that this is in the best interest of the child. The present study aimed to establish whether there is any empirical evidence for this assumption. A literature search was made in PubMed/Medline and PsycINFO to identify studies that had assessed psychological outcomes of children and quality of parenting after infertility treatment. Eight studies met the following inclusion criteria: published in an English-language peer-reviewed journal between 1978 and 2002, and focused on psychosocial child development and quality of parenting after infertility treatment in the above-mentioned special patient groups. All reviewed studies focused on lesbian or single-parent families. Overall, the methodological quality of studies as assessed by a standardized set of criteria was high. The evidence of the studies (assessed by the best evidence synthesis method) was strong for the conclusion that in lesbian families the psychosocial development of children (median age 6.1 years) and the quality of parenting are not different from those in healthy heterosexual two-parent families after infertility treatment or natural conception. Therefore, withholding infertility treatment from lesbian families on the assumption that such intervention may not be in the interest of the prospective child seems unjustified. For the other special patient groups, no conclusions could be drawn, because of a lack of relevant studies.

Shortening a quality of life questionnaire for adolescents with chronic pain and its psychometric qualities.

Chronic pain is a common experience in adolescence. To measure its influence on quality of life in adolescents with chronic headache, Langeveld developed the 71-item scale, Quality of Life Headache-Youth. On the basis of this questionnaire we develop a shortened list, also suitable for other pain locations to enhance compliance. For this, we tested a sample of 98 adolescents from an open population with chronic benign pain. This article presents the psychometric qualities of the shortened version, named the Quality of Life Questionnaire for Adolescents with Chronic Pain. The original version could be reduced to 44 items which showed suitable internal consistency and construct validity against COOP/WONCA charts.

Quality of life in adolescents with chronic pain in the head or at other locations.

The differences in quality of life and school absence were studied in one hundred adolescents from the open population who had reported chronic headache or chronic, physically unexplained, pain at other locations. The adolescents kept a 3-week diary about their pain and completed a quality of life questionnaire. Of all chronic pain sufferers in this study, it was the adolescents with headache who showed the least frequent pain, but they reported the poorest quality of life and the largest school absence due to their pain. Adolescents with headache or adolescents with back pain showed the highest negative correlations between pain parameters and quality of life. Headache sufferers showed highly negative relationships between pain parameters and most quality of life domains (median r = -0.46), and only in headache sufferers did this involve both intensity and frequency of pain. Qualitative studies are needed to reveal the background to these differences.

Chronic pain and its impact on quality of life in adolescents and their families.

OBJECTIVE: To study chronic pain not caused by somatic disease in adolescents and the effect of pain on the quality of life of the adolescents and their families. METHODS: One hundred twenty-eight youngsters (12-18 years) who had reported chronic pain kept a 3-week diary of their pain and completed a questionnaire on quality of life. Their mothers completed a questionnaire on the impact of their youngster's pain on the family. RESULTS: The most prevalent pains were limb pain, headache, abdominal, and back pain. The pain increased during the day, with the highest frequency around dinner time and the highest intensity around bedtime. Girls reported more intense and more frequent pain than boys. The higher the intensity and frequency of the pain, the lower the self-reported quality of life of the female or male adolescent, especially regarding psychological functioning (e.g. feeling less at ease), physical status (a greater incidence of other somatic complaints), and functional status (more impediments to leisure and daily activities). Chronic pain also had a negative impact on family life. The mothers reported restrictions, particularly in social life, and problems dealing with the stress of the adolescent's pain. CONCLUSIONS: Chronic pain, not caused by somatic disease, was present to a higher degree in girls; the pain increased during the day and had a negative impact on quality of life of the adolescents and the family. There is a need for future research aimed at identifying risk factors for chronic pain and pain-associated quality of life in children and adolescents.

Chronic pain among children and adolescents: physician consultation and medication use.

OBJECTIVE: The goal of this study was to assess physician consultation and use of medication in Dutch children and adolescents (0-18 years old) having chronic pain in relation to sociodemographic factors and pain characteristics. DESIGN: This was a population-based cross-sectional survey. A questionnaire was either mailed to the participants' parents or distributed at school, and it was filled out by the parents (for children aged 0-7 years) or by the participant (for children and adolescents aged 8-18 years). SETTING: The study was conducted in the Rotterdam area. PATIENTS: Participants included a random sample of 1,300 children aged 0 to 3 years taken from the register of population. In addition, 41 schools were selected to obtain a representative sample of 5,336 children and adolescents aged 4 to 18 years. OUTCOME MEASURES: Reported physician consultation and medication use were assessed. RESULTS: Of the 6,636 children and adolescents surveyed, 5,424 (82%) responded. A total of 1,358 respondents (25%) reported chronic pain. Of these, 57% had consulted a physician and 39% had used medication for the pain. Respondents with earache, more intense pain, and more frequent pain and those attending lower vocational training programs were more likely to consult a physician for the pain than the average respondent. Respondents with earache, sore throat, headache, more intense pain, and multiple pain; children aged 0 to 3 years; and girls were more likely to use medication for the pain. Logistic regression analyses showed that for physician consultation, the most significant predictive factors were the intensity of pain, age, and earache as well as the level of education for respondents aged 12 to 16 years. The use of medication was predicted by earache, headache, limb pain, intensity of pain, and age. CONCLUSIONS: Chronic pain is a common complaint in children and adolescents, frequently resulting in consultation of a physician and medication use. Regarding physician consultation, children and adolescents with a lower educational level seem to be a group at risk.

Prenatal consultation after a fetal anomaly scan: videotaped exploration of physician's attitude and patient's satisfaction.

The main aim of the study was to evaluate the relationship between the physician's attitude (using the non-verbal Global Affective Measure of the Roter Analaysis System and the Counselor Rating Form-short version) and the satisfaction of the pregnant women with the prenatal consultation. A secondary aim was to evaluate the women's recall of essential information (i.e. location, severity, prognosis and cause of the anomaly). To this end, 24 prenatal consultations (pregnant women, partners and physicians) were videotaped following a fetal anomaly scan, and a few days later, the pregnant women completed questionnaires to assess their perception of the physician's attitude and their satisfaction with the consultation and the extent to which they could recall the essentials of the information given about the fetal anomaly. In descending order, the physician's dominance/assertiveness (i.e. being self-confident and decisive) (assessment of the videotapes by two psychologists), trustworthiness (women's report) and expertise were significantly positively associated with the women's overall satisfaction, i.e. satisfaction with the information given and affective behaviour on the part of the physician during the prenatal consultation. All the women (n=24) recalled the essentials of the information given about the location of the fetal anomaly. The majority of them correctly reproduced the severity, the prognosis and the cause of the anomaly. Our findings indicate that women in whom a fetal anomaly has been detected derive particular benefit from a self-confident, decisive, expert and trustworthy physician.

Brief report: parental burden and grief one year after the birth of a child with a congenital anomaly.

OBJECTIVE: To assess parental burden and grief one year after having a child with a congenital anomaly. METHOD: Twenty-five couples completed the Impact on Family Scale (IFS) and 22 couples answered the Perinatal Grief Scale (PGS). In addition, 27 mothers completed the Functional Health Status Scale (FSII-R). RESULTS: Mothers and fathers showed no significant differences in overall burden (IFS) and grief (PGS). Regarding the subscales, mothers reported significantly more personal strain. Foreknowledge from prenatal diagnosis about the anomaly, a low perceived functional health status of the child, and multiple congenital anomalies increased the burden and grief. CONCLUSIONS: A perinatal counseling team that provides clear and consistent information about the anomalies, the treatment, and the prognosis would help to reduce unnecessary stress and uncertainty, particularly for parents who received prenatal information and whose infant has multiple congenital anomalies.

Cognitions, emotions, and behavior of patients with migraine when taking medication during an attack.

Fifty-three patients with migraine, recruited from the Dutch Society of Migraine Patients and a general practice, were investigated regarding pain, moods, thoughts, and functioning during their most recent migraine attack, using a semistructured interview. Salient findings were: the high pain intensity the patients endured before they took analgesic medication, concerns about medication damaging their health, overoptimism regarding the effect of analgesic medication, and the relatively large proportion of patients (43%) who took medication primarily to be able to continue their activities. We recommend that future clinical trials on the effects of medication on migraine should not only include the measurement of pain during the attack, but also emotions, concerns about potential side effects and the ability to continue or resume work. Furthermore, it is important to provide patients with information about the side effects of medication and to apply cognitive-behavioral techniques for improvement of their mood during the attack.

Trait anxiety, negative emotions, and the mothers' adaptation to an infant born subsequent to late pregnancy loss: a case-control study.

Women with (n = 27) a history of late pregnancy loss (> or = 20 weeks) due to congenital anomalies who had completed the subsequent pregnancy with a live-birth were compared with a group of mothers with newborns without such a history (n = 29) at 4 and 16 weeks post-partum. The following aspects were assessed; depression, anxiety, psychological distress, and mother-infant adaptation. The women with a previous pregnancy loss showed significantly more negative emotions than the women without such a history. In addition, they considered that their healthy baby experienced more problems with sleeping, crying, eating, and acquiring a regular pattern of this behaviour than the average baby. They also perceived their baby as being less ideal than the women without a previous pregnancy loss. These problems were particularly present 4 weeks post-partum and were significantly positively related to trait anxiety. The implications of this study are that in women with a history of late pregnancy loss, family physicians and welfare officers should be made aware of possible problems in the mother and in mother-infant adaptation shortly after a normal live-birth, particularly in those with high trait anxiety. They will then be able to arrange psychological support at an early stage.

Measuring chronic pain in children, an exploration.

The study focused on the feasibility and validity of pain instruments and the optimal period of diary registration for measuring chronic pain intensity of 13 children. Highly positive associations were found between the registration of pain on a Visual Analogue Scale and on the Postoperative Pain Measure for Parents. For children under medical treatment for chronic limb pain a one-week dairy registration suffices.

The grief of late pregnancy loss.

We studied 46 women who had an ultrasound diagnosis of a lethal fetal anomaly (gestational age > or = 24 weeks). Shortly after the diagnosis, 45% of these 46 women showed severe psychological instability established by a consensus diagnosis. Three months later, this percentage had diminished significantly to 22%. The total GHQ-28 score revealed that after 4 years, 11 out of the 29 remaining participants (38%) had a score of 5 or more, which indicated a clinically significant degree of general psychological distress. Depression and despair measured with the Perinatal Grief scale, did not decrease significantly over the 4-year period. Women with a strong disposition towards feelings of inadequacy or 'neuroticism', measured with the Dutch Personality Questionnaire, displayed significantly more intense grief reactions than women without such a strong disposition. The implications of our study are that in the face of (threatened) late pregnancy loss, medical care should include (i) paying attention to the need for medical information and emotional support and (ii) performing psychosocial screening of women identified as showing signs of inadequacy.

Prediction and course of grief four years after perinatal loss due to congenital anomalies: a follow-up study.

The emotional reactions of women (N = 29) after perinatal loss were evaluated over a four-year period by means of standardized questionnaires and a semi-structured interview. Eleven women (38 per cent) displayed a level of general psychological distress which is clinically significant. Grief reactions declined significantly during this period, except for difficulties with coping and despair concerning the loss, and a quarter of the women still showed a clinically significant high level of distress for intrusive images. The disposition for feelings of inadequacy (i.e. feeling anxious, insufficient, depressed and having low self-esteem) was strongly and positively related to the intensity of stress, grief and general psychological distress after four years. Our findings emphasize the importance of psychosocial screening of those women identified as showing signs of inadequacy in the face of (threatened) pregnancy loss with the objective to offer them additional psychological support.
