Women's adjustment trajectories during IVF and impact on mental health 11–17 years later

STUDY QUESTION Do patients present different adjustment trajectories during and after IVF treatment? SUMMARY ANSWER Most women show resilient trajectories during and after IVF treatment but 37% show temporary or chronic maladjustment during IVF and 10% are maladjusted 11–17 years after treatment. WHAT IS KNOWN ALREADY Research on patient psychosocial adjustment during treatment has contributed to identifying the most distressful stages of IVF treatment and profiling patients at risk for emotional maladjustment at these specific stages. This knowledge is currently driving the deliverance of psychosocial care at fertility clinics by tailoring it to patients' risk profiles and specific treatment stages. However, current care does not take into consideration how individuals adjust across the entire treatment pathway. This can be assessed by profiling individual adjustment trajectories. STUDY DESIGN, SIZE, DURATION A longitudinal cohort study with five assessment moments that combines data from two different studies, the STRESSIVF and OMEGA projects. Participants enrolled in the STRESSIVF study (started IVF in 1998–2000) were assessed before and after the first IVF treatment cycle and 6 months and 2.5 years after the last IVF cycle. A subset participated in the OMEGA project (started IVF in 1995–2000) and reported on their mental health 11–17 years after treatment. PARTICIPANTS/MATERIALS, SETTING, METHODS Three hundred and forty-eight women participated in the STRESSIVF project and 108 of these in the OMEGA. Anxiety was measured with the State and Trait Anxiety Inventory, depression with the Beck Depression Inventory and mental health with the Mental Health Inventory. Latent class growth mixed modelling was carried out to identify distinct anxiety and depression trajectories over the four STRESSIVF study assessment moments. Multinominal logistic regressions were conducted to investigate predictors of trajectory membership, and stepwise linear regressions were performed to investigate if adjustment trajectories predicted mental health 11–17 years after IVF treatment. MAIN RESULTS AND THE ROLE OF CHANCE A total of 67 and 86% of women showed normal levels of anxiety and depression, respectively, throughout treatment (resilient trajectories), 24 and 33% experienced anxiety and depression only during treatment (recovery trajectories), 4.6 and 4.9% experienced anxiety and depression only after treatment (delayed trajectories), and 4.3% showed chronic anxiety (chronic trajectory, not identified for depression). Non-resilient trajectories were associated with unsuccessful treatment, marital dissatisfaction, lack of social support and negative infertility cognitions. One in 10 women had a delayed or chronic trajectory and these trajectories predicted serious mental health impairment 11–17 years after treatment. LIMITATIONS, REASONS FOR CAUTION The study only focuses on women. In the OMEGA project adjustment was assessed using a mental health measure. Although we could investigate how trajectories predicted mental health, it would have been preferable to map anxiety and depression trajectories up to 11–17 years after treatment. Missing analysis showed selective dropout from the study but this was accounted for by using mixed models and imputation procedures. Finally, data on other life stressors were not collected; therefore any contribution from these events cannot be assessed. WIDER IMPLICATIONS OF THE FINDINGS Fertility health-care providers have been called upon considering their responsibility in supporting patients in the aftermath of treatment. Results show it is possible to profile different groups of at-risk women at the start of the treatment and tailor psychosocial support to risk profile to promote health adjustment during treatment and thereafter

How about your peers? Cystic fibrosis questionnaire data from healthy children and adolescents

Contains fulltext : 97967.pdf (publisher's version ) (Open Access)BACKGROUND: The Cystic Fibrosis Questionnaire (CFQ) is widely used in research as an instrument to measure quality of life in patients with cystic fibrosis (CF). In routine patient care however, measuring quality of life is still not implemented in guidelines. One of the reasons might be the lack of consensus on how to interpret CFQ scores of an individual patient, because appropriate reference data are lacking. The question which scores reflect normal functioning and which scores reflect clinically relevant problems is still unanswered. Moreover, there is no knowledge about how healthy children and adolescents report on their quality of life (on the CFQ). With regard to quality of life the effect of normal development should be taken into account, especially in childhood and adolescence. Therefore, it is important to gain more knowledge about how healthy children and adolescents report on their quality of life and if there are any difference in a healthy populations based on age or gender. Without these data we cannot adequately interpret the CFQ as a tool in clinical care to provide patient-tailored care. Therefore this study collected data of the CFQ in healthy children and adolescents with the aim to refer health status of CF youngsters to that of healthy peers. METHODS: The CFQ was completed by 478 healthy Dutch children and adolescents (aged 6-20) in a cross-sectional study. RESULTS: The majority of healthy children (over 65%) did not reach maximum scores on most domains of the CFQ. Median CFQ-scores of healthy children and adolescents ranged from 67 to 100 (on a scale of 0-100) on the different CFQ-domains. Significant differences in quality of life exist among healthy children and adolescents, and these depend on age and gender. CONCLUSIONS: Reference data of quality of life scores from a healthy population are essential for adequate interpretation of quality of life in young patients with CF. Clinicians should be aware that the perception of health-related quality of life is not as disease-specific as one might think and also relies on factors such as age, normal maturation and gender

Behaviour and resistance of composite slabs : experiments and finite element analysis

Composite slab flooring systems are used in steel framed buildings as well as in conjunction with concrete, prestressed concrete and timber structures. Composite slabs consist of a thin-walled profiled steel sheet, reinforcement and in-situ cast concrete. The profiled sheeting acts as permanent formwork and once the concrete has hardened as an outer reinforcement. Unlike a bar reinforcement, the sheeting does not benefit from being totally embedded in concrete. Partial connection between the sheeting and concrete takes place after the adhesion is broken. Composite slab design is usually based on parameters of partial connection obtained from full scale bending test. The objective of this thesis is to analyse composite slabs which fail in longitudinal shear and flexural failure. An analytical approach based on FE simulations and data from small scale tests (detail tests) has been used. A new test rig has been designed and a procedure developed to evaluate the characteristics of the interaction. Mechanical interlocking resistance, reduction of mechanical interlocking due to high strains in the sheeting, and friction between sheeting and concrete has been assessed. Cracking of concrete in composite slabs has a major influence on the distribution of horizontal shear forces between the sheeting and concrete, and consequently on the behaviour of the composite slab. An intensive FE nonlinear study has therefore been performed to examine various concepts of concrete cracking. FE predictions have been validated with the full scale tests and the good agreement obtained shows that modeling and input data were correct. Results of small scale tests and FE calculations have increased the knowledge of composite slab behaviour. A parametric study of the influence of load arrangements and various characteristic of partial connection have created the basis for an improved design method. A design method based on small scale tests and FE calculation is proposed. It uses a simple structural model and a new concept of transfer length to properly define a parth of slab length mobilized for longitudinal shear connection. The design method is an improved version of existing partial connection strength method described in Eurocode 4. The method is applicable for ductile and non ductile slabs and accounts for various loading arrangements in a consistent manner. Design recommendations for a general load arrangement are given.Godkänd; 1996; 20070428 (ysko

Weaknesses, strengths and needs in fertility care according to patients.

Contains fulltext : 87470.pdf (publisher's version ) (Closed access)BACKGROUND: The patients' role in assessing health care quality is increasingly recognized. Measuring patients' specific experiences and needs generates concrete information for care improvement, whereas satisfaction surveys only give an overoptimistic, undifferentiating picture. Therefore, this study aimed to investigate possible weaknesses, strengths and needs in fertility care by measuring patients' specific experiences. METHODS: Mixed (qualitative and quantitative) methods were used to identify weaknesses, strengths and needs in fertility care. Four focus groups with 21 infertile patients were used for documenting care aspects relevant to patients. The fully transcribed qualitative results were analysed and converted into a 124-item questionnaire, to investigate whether these aspects were regarded as weaknesses, strengths or needs in fertility care. The questionnaire was distributed to 369 eligible couples attending 13 Dutch fertility clinics. Descriptive statistics were used to determine the quantity of the weaknesses, strengths and needs. RESULTS: Overall, 286 women (78%) and 280 men (76%) completed the questionnaire. Patients experienced many weaknesses in fertility care, mostly regarding emotional support and continuity of care. Respect and autonomy and partner involvement were considered strengths in current care. Furthermore, women expressed their need for more doctors' continuity during their treatment, and couples strongly desired to have free access to their own medical record. The questionnaire's internal consistency and construct validity were sufficient. CONCLUSIONS: Infertile couples experience strengths, but also many weaknesses and needs in current fertility care. Lack of patient centredness seems to be a major cause herein. Using mixed methods is a sensitive means for identifying these weaknesses and needs.1 januari 201
