Systematic development of a mobile preconception lifestyle programme for couples undergoing IVF: the PreLiFe-programme.

STUDY QUESTION: Can we develop a preconception lifestyle programme for couples undergoing IVF that is in line with their needs. SUMMARY ANSWER: A mobile preconception lifestyle programme was systematically developed based on expert opinion, literature and needs of IVF-patients. WHAT IS KNOWN ALREADY: A healthy lifestyle prior to conception is not only beneficial for the general health of couples, but evidence on its importance for their reproductive health and the health of their children is also emerging. So far, the vast majority of fertility clinics do not offer a lifestyle programme for couples undergoing IVF. Therefore, the present study aimed to develop a lifestyle programme for IVF-couples. STUDY DESIGN, SIZE, DURATION: The development of the PreLiFe-programme was guided by the steps of the Medical Research Council (MRC) framework for developing complex interventions, a systematic approach for developing theory- and evidence-based health promotion interventions. PARTICIPANTS/MATERIALS, SETTINGS, METHODS: First, the evidence base on lifestyle programmes for IVF-couples was reviewed. Second, several iterations between an expert panel, the literature, and quantitative and qualitative data from IVF-patients identified the content, the format, behaviour change techniques and theory of the programme. Third, the PreLiFe-programme was produced and the expected process and outcomes of a randomized controlled trial assessing it were modelled. Finally, user tests among experts and patients and pilot tests among patients were conducted. MAIN RESULTS AND ROLE OF CHANCE: The finally developed PreLiFe-programme is a mobile application to be used autonomously by both partners of IVF-couples during the first year of IVF, in combination with motivational interviewing over the telephone every three months (i.e. blended care). The PreLiFe-programme provides advice and skills training on physical activity, diet and mindfulness based stress reduction and is in part tailored based on monitoring and tracking the lifestyle of patients. Based on the literature the expert panel considers it plausible that all three components contribute to IVF-success rates. The PreLiFe-programme is likely to be acceptable to patients as it meets the need of patients for lifestyle advice and treatment information. LIMITATIONS, REASON FOR CAUTION: The pilot in IVF-couples had a 3-month duration. The feasibility of the PreLiFe-programme in other infertile populations and/or upon longer use is yet to be examined. Whether the PreLiFe-programme effectively improves lifestyle and IVF-success rates is currently being examined in a trial randomizing heterosexual couples starting IVF to the PreLiFe-programme or an attention-control group for 12 months. WIDER IMPLICATIONS OF THE FINDINGS: If the PreLiFe-programme improves lifestyle and the chance of IVF-success, it will be a powerful tool and provide guidance for implementing lifestyle programmes in fertility clinics.

Impact of ARTs on oncological outcomes in young breast cancer survivors.

STUDY QUESTION: What is the risk of recurrence in young breast cancer survivors who undergo ARTs following completion of anticancer treatment? SUMMARY ANSWER: ART in breast cancer survivors does not appear to have a negative impact on disease-free survival. WHAT IS KNOWN ALREADY: In healthy women, fertility treatment does not increase the risk of developing breast cancer. At the time of breast cancer diagnosis and before starting anticancer treatments, several studies have shown the safety of performing ART. However, the safety of ART in breast cancer survivors following completion of anticancer treatment remains under-investigated. In general, breast cancer survivors are counselled to avoid any hormonal treatment but there are limited data available on the effect of short exposure to high oestradiol levels during ART. The largest study in this regard included 25 breast cancer survivors exposed to ART and did not show a detrimental effect of ART on patient survival. Hence, taking into account that pregnancy after breast cancer does not affect cancer prognosis, defining the safety of ART in breast cancer survivors remains a priority. STUDY DESIGN, SIZE, DURATION: We conducted a retrospective multicentric matched cohort study including a cohort of breast cancer survivors who underwent ART (exposed patients) between January 2006 and December 2016. Exposed patients who were eligible for the study were matched according to known breast cancer prognostic factors. Matched breast cancer survivors did not undergo ART (non-exposed patients) and were disease-free for a minimum time that was not less than the time elapsed between breast cancer diagnosis and first ART for the matched ART-exposed patients. PARTICIPANTS/MATERIALS, SETTING, METHODS: Data were retrieved from all survivors who had been diagnosed with breast cancer in eight participating centres at an age of ≤40 years, without metastasis, ongoing pregnancy, pre-existing neoplasia or ovarian failure. ART included ovarian stimulation for IVF/ICSI, clomiphene citrate treatment and hormone replacement therapy for embryo transfer. Data were collected from an oncological database for the selection of breast cancer patients in the non-exposed group. Exposed patients were matched (1:2) for germline BRCA status, tumour stage, anticancer treatment and age, whenever feasible. Matched groups were compared at baseline according to characteristics using conditional logistic regression. Kaplan-Meier curves were constructed to compare time to recurrence between groups, with the time of ART as starting point that has been adjusted in the non-exposed group. The analyses were performed using Stata IC/15.1. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 39 breast cancer patients in the ART group were eligible for the analysis and were matched with 73 controls. There was no statistical difference between the two groups for the presence of BRCA mutation, tumour characteristics, use of (neo)adjuvant chemotherapy and of adjuvant endocrine therapy. Exposed patients were younger than non-exposed patients (mean age 31.8 vs 34.3 years, respectively; P < 0.001). In the ART group, 89.7% were nulliparous at diagnosis compared to 46.6% of controls (P < 0.001). ART was performed at a mean age of 37.1 years old, after a median time of 4.1 years following breast cancer diagnosis (range: 1.5-12.5). Median anti-Müllerian hormone at the time of ART was 0.28 ng/ml (range: 0-4.4) and median serum oestradiol peak level was 696.5 pg/ml (range: 139.7-4130). Median follow-up time from first attempt of ART was 4.6 years (range: 2.4-12.5) in the ART group. Adjusted follow-up time for the non-exposed group was 6.9 years (range: 1.1-16.5 years) (P = 0.004). In the ART group, 59% of patients had a pregnancy after breast cancer compared to 26% in the non-exposed patients (P = 0.001). Breast cancer relapsed in 7.7% versus 20.5% women in the ART and non-exposed groups, respectively (hazard ratio 0.46, 95% CI 0.13-1.62, P = 0.23). Median time to relapse was 1.3 (range: 0.3-2.7) years versus 4.5 (range: 0.4-11.1) years after ART and adjusted time in the ART and non-exposed groups, respectively (P = 0.14). LIMITATIONS, REASONS FOR CAUTION: Although this is the first and largest multicentric study addressing the impact of ART on breast cancer recurrence to provide data on oestrogen exposure, only a small number of patients could be included. This reflects the reluctance of breast cancer survivors and/or oncologists to perform ART, and highlights the need for a prospective data registry to confirm the safety of this approach. This would offer the possibility for these patients, who are at a high risk of infertility, to fully benefit from ART. WIDER IMPLICATIONS OF THE FINDINGS: Although recent studies have proven that pregnancy after breast cancer has no detrimental impact on prognosis, counselling patients about the safety of ART remains challenging. Our study provides reassuring data on the use of ART in breast cancer survivors with favourable prognostic factors, for when natural conception fails.

Polycystic ovarian morphology and the diagnosis of polycystic ovary syndrome: redefining threshold levels for follicle count and serum anti-Müllerian hormone using cluster analysis.

STUDY QUESTION: Can cluster analysis be used to differentiate between normo-ovulatory women with normal ovaries and normo-ovulatory women with polycystic ovarian morphology (PCOM) in a non-subjective manner? SUMMARY ANSWER: Cluster analysis can be used to accurately and non-subjectively differentiate between normo-ovulatory women with normal ovaries and normo-ovulatory women with PCOM. WHAT IS KNOWN ALREADY: Currently, PCOM is diagnosed using a fixed threshold level, i.e. 12 or more follicles per ovary, and is one of the diagnostic criteria of polycystic ovary syndrome (PCOS). However, PCOM is also encountered in normo-ovulatory women, suggesting that it could just represent a normal variant. On the other hand, recent studies have shown subtle endocrine abnormalities in women with isolated PCOM that resemble those found in women with PCOS. Because of the strong correlation between anti-Müllerian hormone (AMH) and follicle number, a high serum AMH level has been proposed as a surrogate marker for PCOM and could, therefore, be integrated in the diagnostic classifications for PCOS. STUDY DESIGN, SIZE, DURATION: This was a retrospective observational cohort study. Original cohorts had been recruited for previous studies between 1998 and 2010. Two hundred ninety-seven regularly cycling women and 700 women with PCOS were eligible for inclusion. PARTICIPANTS/MATERIALS, SETTING, METHODS: Cluster analysis was performed in 297 regularly cycling women. After exclusion of 'PCOM' clusters, each 'non-PCOM' cluster (young, n = 118 and old, n = 100) was included in the construction of a receiver operating characteristics curve to test the diagnostic performance of follicle number per ovary (FNPO) and serum AMH in discriminating similarly aged full-blown PCOS patients (n = 411 and 237, respectively) from normal regularly cycling non-PCOM women. MAIN RESULTS AND ROLE OF CHANCE: The optimal number of clusters was four; age was the most important classifying variable, followed by the FNPO and serum AMH. Two distinct clusters of normo-ovulatory women with PCOM were isolated and differed solely by age, i.e. 'young' and 'old'. Both 'PCOM' clusters had their similarly aged counterpart of 'non-PCOM' clusters. Likewise, two clusters comprised women younger than 30 years, with (n = 28, 'PCOM regularly cycling women') or without (n = 118, 'normal regularly cycling women') features of PCOM (increased FNPO and/or serum AMH). The two other clusters in older women could be labelled 'normal regularly cycling women' or 'PCOM regularly cycling women' (n = 100 and 51, respectively). The prevalence of PCOM was significantly greater in old than in young regularly cycling women controls. In the young population, after exclusion of the 'PCOM regularly cycling women', the diagnostic performance of AMH, expressed by area under the curve (AUC) (AUC = 0.903; CI (0.876-0.930)) to differentiate PCOS women from normal regularly cycling women was similar to that using the FNPO (AUC = 0.915, CI (0.891-0.940)) (P = 0.25), confirming results from earlier studies. In the old population, the diagnostic performance of AMH was greater than that of FNPO (AUCs = 0.948 (0.927-0.970) vs 0.874 (0.836-0.912), respectively, P = 0.00035). Cut-off levels of AMH and antral follicle count distinguishing regularly cycling non-PCOM women from PCOS women were higher in young women than in older women. LIMITATIONS, REASONS FOR CAUTION: Data of normal women were obtained from earlier studies, aiming to measure normal endocrine values. Apparently, the strong effect of age in cluster analysis revealed a dichotomy in the age distribution among the cohort of regularly cycling women included. This was involuntary since in none of the original studies, eligibility was limited by age and there was considerable overlap in age ranges of the cohorts. Transvaginal ultrasound was performed using a 6.5-8 mHz probe and our data confirm that this threshold level for FNPO is still valid if using such probe frequencies, although the use of devices with a maximum frequency lower than 8 mHz has become obsolete. Obviously, newer ultrasound scanner using higher transducer frequency will facilitate the detection of more follicles. WIDER IMPLICATIONS OF THE FINDINGS: Our data support the use of AMH as a surrogate for ultrasound to define PCOM, which is one of the three items of the Rotterdam classification. They also show that age should be taken into account to define the optimal threshold. The fact that the prevalence of PCOM was increased in the older regularly cycling women, may be due to 'attenuated' PCOS, a phenomenon that has been described in ageing women with PCOS. These women might have had anovulatory cycles in the past and have become ovulatory with increasing age, and were, therefore, eligible for this study. However, since most women included at older age have had spontaneous pregnancies in the past, PCOM at older age may be associated with a subclinical form of PCOS, which may also be present in young regularly cycling women.

Serum anti-müllerian hormone levels in healthy females: a nomogram ranging from infancy to adulthood.

CONTEXT: Anti-müllerian hormone (AMH) is an accurate marker of ovarian reserve. However, sufficiently large sets of normative data from infancy to the end of reproductive life are scarce. OBJECTIVE: This study was an assessment of serum AMH levels in healthy females. SUBJECTS: In 804 healthy females ranging from infancy until the end of the reproductive period, serum AMH levels were measured with an enzyme-linked immunometric assay. All adults had regular menstrual cycles. The majority was proven fertile and none of them had used oral contraceptive pills prior to study inclusion. RESULTS: In the total cohort, AMH was inversely correlated with age (r = -0.24; P < 0.001). The age at which the maximum AMH value was attained was at 15.8 yr. In girls younger than 15.8 yr, serum AMH and age were positively correlated (r = +0.18; P = 0.007). Thereafter AMH levels remained stable (r = -0.33; P = 0.66), whereas from the age of 25.0 yr onward, an inverse correlation between AMH and age (r = -0.47; P < 0.001) was observed. At any given age, considerable interindividual differences in serum AMH levels were observed. CONCLUSION: During infancy AMH levels increase, whereas during adolescence, a plateau until the age of 25 yr was observed. From the age of 25 yr onward, serum AMH levels correlate inversely with age, implying that AMH is applicable as a marker of ovarian reserve only in women of 25 yr old and older. Our nomogram may facilitate counseling women on their reproductive potential.

Pregnancy outcome in female childhood cancer survivors.

BACKGROUND: The number of childhood cancer survivors has dramatically increased and consequently, an increasing number of survivors may now wish to conceive. Recently, several studies have described that previous treatment with abdominal radiotherapy may increase the risk of adverse pregnancy outcome. METHODS: We conducted a retrospective single centre cohort study of childhood cancer survivors with a singleton live birth between January 2000 and December 2005. Pregnancy outcome was compared with data from the Netherlands Perinatal Registry, a nationwide database of pregnancy outcome parameters of all births in the Netherlands registered by midwives, obstetricians and paediatricians. RESULTS: Data were available on 40 survivors and 9031 controls. Median age at diagnosis was 6.9 years (range 0.1-16.8 years). The median interval between diagnosis and date of delivery was 21.6 years (range 7.4-36.1 years). In the whole cohort, pregnancy outcome was not different between survivors and controls. However, survivors treated with abdominal radiotherapy delivered preterm and had post-partum haemorrhage (mean gestational age in survivors = 34.9 versus 39.2 weeks in controls, P = 0.001; 33% in survivors versus 5% in controls, P = 0.007, respectively). The offspring of survivors had normal birthweight after adjustment for gestational age (mean birthweight in offspring of survivors 2503 versus 1985 g; P = 0.22). CONCLUSION: Childhood cancer survivors irradiated to the abdomen have an earlier delivery and higher incidence of post-partum haemorrhage. This stresses the need for close monitoring of the delivery, including inpatient perinatal care, in this group of childhood cancer survivors.

Assessment of ovarian reserve in adult childhood cancer survivors using anti-Müllerian hormone.

BACKGROUND: The aim was to assess possible treatment-induced gonadal damage in a cohort of adult female childhood cancer survivors (CCS) using anti-Müllerian hormone (AMH), the most sensitive marker of ovarian reserve. METHODS: A total cohort of 185 survivors was compared with 42 control subjects. The median follow-up time was 18.1 years (range 4.1-43.2 year). RESULTS: Median AMH concentrations in the analysed cohort were not different from controls (median 1.7 versus 2.1 microg/l; P = 0.57). However, AMH levels were lower than the 10th percentile of normal values in 27% (49/182) of our survivors. In addition, 43% (79/182) had AMH levels lower than 1.4 microg/l, a previously established cut-off value which predicts ongoing pregnancy after assisted reproduction. There were no differences in AMH levels in subgroups classified according to disease. However, survivors treated with three or more procarbazine containing chemotherapy cycles had significantly lower AMH levels than controls (median 0.5 microg/l; P = 0.004). Also survivors treated with abdominal or total body irradiation had significantly lower AMH levels than controls (median < 0.1 microg/l; P < 0.001). CONCLUSIONS: AMH can be used to identify subgroups of CCS at risk for decreased fertility or premature ovarian failure. In these survivors, options for fertility preservation should be considered prior to starting treatment since they may be at risk for poor chances of pregnancy after assisted reproductive treatment.

Anti-Müllerian hormone: a marker for oocyte quantity, oocyte quality and embryo quality?

Serum anti-Müllerian hormone (AMH) concentrations decline with increasing age and constitute a sensitive marker for ovarian ageing. In addition, basal serum AMH concentrations predict ovarian response during IVF cycles. Concomitantly, oocyte quantity and embryo quality decrease with advancing age. Hence, it was postulated that AMH in serum constitutes a marker for embryo quality. Women aged 37 years and younger with regular menstrual cycles, normal body mass index and partners with normal semen parameters were randomly assigned to either a standard or mild stimulation protocol for IVF treatment. Blood samples were drawn at cycle day 3 and at the day of human chorionic gonadotrophin administration. Embryo quality was assessed using embryo morphology score and preimplantation genetic screening. Serum AMH concentrations on cycle day 3 were correlated with the number of oocytes retrieved in both groups. AMH and embryo morphology were correlated after mild stimulation, but not after conventional ovarian stimulation. AMH and the chromosomal competence of embryos were not correlated. Serum AMH is predictive for ovarian response to stimulation. However, the lack of a consistent correlation with embryo morphology and embryo aneuploidy rate is not in favour of a direct relationship between oocyte quantity and embryo quality.

Anti-müllerian hormone as a marker of ovarian function in women after chemotherapy and radiotherapy for haematological malignancies.

BACKGROUND: In female cancer survivors, the accelerated loss of primordial follicles as a result of gonadal damage may lead to premature ovarian failure (POF). However, the extent of the damage is unpredictable. Anti-Müllerian hormone (AMH) constitutes a sensitive marker of ovarian reserve. Serum AMH levels were measured to assess sub-clinical ovarian damage in patients treated with gonadotoxic therapy. METHODS: In 25 patients with haematological malignancies, serum AMH concentrations were measured prior to and after cancer therapy and were compared with normo-ovulatory controls. RESULTS: In all patients, AMH concentrations were lower than controls prior to treatment. Thirteen patients were treated with multi-drug chemotherapy. Although in most patients treated with chemotherapy menstrual cyclicity was restored, median serum AMH levels were lower than in controls. Twelve patients had stem cell transplantation (SCT) after total body irradiation. They all developed POF and their serum AMH concentrations were undetectable. CONCLUSIONS: Female cancer survivors treated with SCT all developed POF. Hence, in these patients fertility preservation should be considered. In patients treated with chemotherapy, ovarian reserve seems to be compromised as well.

Preoperative predictors for residual tumor after surgery in patients with ovarian carcinoma.

OBJECTIVES: Suboptimal debulking (>1 cm residual tumor) results in poor survival rates for patients with an advanced stage of ovarian cancer. The purpose of this study was to develop a prediction model, based on simple preoperative parameters, for patients with an advanced stage of ovarian cancer who are at risk of suboptimal cytoreduction despite maximal surgical effort. METHODS: Retrospective analysis of 187 consecutive patients with a suspected clinical diagnosis of advanced-stage ovarian cancer undergoing upfront debulking between January 1998 and December 2003. Preoperative parameters were Karnofsky performance status, ascites and serum concentrations of CA 125, hemoglobin, albumin, LDH and blood platelets. The main outcome parameter was residual tumor >1 cm. Univariate and multivariate logistic regression was employed for testing possible prediction models. A clinically applicable graphic model (nomogram) for this prediction was to be developed. RESULTS: Serum concentrations of CA 125 and blood platelets in the group with residual tumor >1 cm were higher in comparison to the optimally cytoreduced group (p < 0.0001 and <0.01, respectively). Serum albumin and hemoglobin levels were lower in the group with residual tumor (p < 0.0001 and <0.05, respectively). The frequency of preoperative ascites was higher in the group with residual tumor (p < 0.0005). The prediction model, consisting of CA 125 and albumin, for remaining with residual tumor showed an area under the receiver operating characteristics curve of 0.79. A nomogram for probability of residual tumor >1 cm based on serum levels of CA 125 and albumin was established. CONCLUSION: Postoperative residual tumor despite maximal surgical effort can be predicted by preoperative CA 125 and serum albumin levels. With a nomogram based on these two parameters, probability of postoperative residual tumor in each individual patient can be predicted. This proposed nomogram may be valuable in daily routine practice for counseling and to select treatment modality.

[Preconception care: an essential part of the care for mother and child]. / Preconceptiezorg: een onlosmakelijk onderdeel van de zorg voor moeder en kind.

Despite the modernisation of antenatal care in the Western world, the incidence of a number of adverse pregnancy outcomes, such as birth defects, low birth weight and preterm birth, has not decreased over the past few decades. Since its inception at the beginning of the last century, the concept of antenatal care has not changed. The first antenatal visit typically starts at the end of the first trimester. By this stage of pregnancy organogenesis and early placentation have been completed making it almost impossible to reverse any unfavourable exposure on the foetus. Preconception care addresses risk factors that are present prior to pregnancy. By either eliminating or altering risk factors during this period, pregnancy outcome may improve. The goal of preconception care is to optimise the quality of foetal, newborn and infant life through primary prevention. With regard to genetic conditions the aims of preconception care are more nuanced. The principle components of preconception care include (a) risk assessment, (b) information and advice on health promotion, (c) specific counselling and (d) intervention. The effectiveness of preconception care has been demonstrated in women who are at increased risk of adverse pregnancy outcome. In women at low-risk, however, the usefulness of preconception care has yet to be established. The concept of preconception care is relatively simple, logical and promises much. For preconception care to be a success, it is crucial to make this form of preventive care available to all prospective parents. The Internet could play a major part in the dissemination of information that is relevant to a successful outcome of pregnancy.
