RESUMEN

IVF treatment involving donated eggs increases yearly. Numerous technical and commercial transformations have reshaped how eggs are retrieved, stored and managed. A key transformation is vitrification; a 'fast freezing' method that allows efficient preservation of eggs, and therefore more flexibility in use, giving rise to new commercial possibilities. There has been limited focus on egg providers' experiences in the context of vitrification and related commercialisation. We report findings from a study in the UK, Spain and Belgium, where we interviewed 75 egg providers. Comparing experiences within different donation 'regimes' allows an exploration of how varying national practices and policies shape information-giving and women's experiences. In the UK, a system of 'informed gift-giving' was described, where egg providers saw their actions as not-for-profit and felt relatively well informed. In Belgium, the system was presented as 'trusted tissue exchange': with less information-giving than in the UK, but clinics were trusted to act responsibly. In Spain, a 'closed-door, market-driven' system was described, whereby egg providers received little information and expressed concerns about generation of excess profit. Our findings extend understandings of how egg donation is managed at the national level and how donation regimes produce specific experiences, expectations and subjectivities amongst tissue providers.

RESUMEN

BACKGROUND: Referral and uptake rates of structured self-management education (SSME) for Type 2 diabetes (T2DM) in the UK are variable and relatively low. Research has documented contributing factors at patient, practitioner and organisational levels. We report a project to develop an intervention to improve referral to and uptake of SSME, involving an integrative synthesis of existing datasets and stakeholder consultation and using Normalisation Process Theory (NPT) as a flexible framework to inform the development process. METHODS: A three-phase mixed-methods development process involved: (1) synthesis of existing evidence; (2) stakeholder consultation; and (3) intervention design. The first phase included a secondary analysis of data from existing studies of T2DM SSME programmes and a systematic review of the literature on application of NPT in primary care. Influences on referral and uptake of diabetes SSME were identified, along with insights into implementation processes, using NPT constructs to inform analysis. This gave rise to desirable attributes for an intervention to improve uptake of SSME. The second phase involved engaging with stakeholders to prioritise and then rank these attributes, and develop a list of associated resources needed for delivery. The third phase addressed intervention design. It involved translating the ranked attributes into essential components of a complex intervention, and then further refinement of components and associated resources. RESULTS: In phase 1, synthesised analysis of 64 transcripts and 23 articles generated a longlist of 46 attributes of an embedded SSME, mapped into four overarching domains: valued, integrated, permeable and effectively delivered. Stakeholder engagement in phase 2 progressed this to a priority ranked list of 11. In phase 3, four essential components attending to the prioritised attributes and forming the basis of the intervention were identified: 1) a clear marketing strategy for SSME; 2) a user friendly and effective referral pathway; 3) new/amended professional roles; and 4) a toolkit of resources. CONCLUSIONS: NPT provides a flexible framework for synthesising evidence for the purpose of developing a complex intervention designed to increase and reduce variation in uptake to SSME programmes in primary care settings.

RESUMEN

Information received by women regarding physical activity during and after pregnancy often lacks clarity and may be conflicting and confusing. Without clear, engaging, accessible guidance centred on the experiences of pregnancy and parenting, the benefits of physical activity can be lost. We describe a collaborative process to inform the design of evidence-based, user-centred physical activity resources which reflect diverse experiences of pregnancy and early parenthood. Two iterative, collaborative phases involving patient and public involvement (PPI) workshops, a scoping survey (n = 553) and stakeholder events engaged women and maternity, policy and physical activity stakeholders to inform pilot resource development. These activities shaped understanding of challenges experienced by maternity and physical activity service providers, pregnant women and new mothers in relation to supporting physical activity. Working collaboratively with women and stakeholders, we co-designed pilot resources and identified important considerations for future resource development. Outcomes and lessons learned from this process will inform further work to support physical activity during pregnancy and beyond, but also wider health research where such collaborative approaches are important. We hope that drawing on our experiences and sharing outcomes from this work provide useful information for researchers, healthcare professionals, policy makers and those involved in supporting physical activity behaviour.

RESUMEN

In this paper, we draw on three ethnographic studies of surrogacy we carried out separately in different contexts: the western US state of California, the south Indian state of Karnataka, and the western Russian metropolis of St Petersburg. In our interviews with surrogate mothers, intended parents, and surrogacy professionals, we traced the meanings and ideologies through which they understood the clinical labour of surrogacy. We found that in the US, interviewed surrogates, intended parents and professionals understood surrogacy as an exchange of both gifts and commodities, where gift-giving, reciprocity, and relatedness between surrogates and intended parents were the major tropes. In India, differing narratives of surrogacy were offered by its different parties: whilst professionals and intended parents framed it as a win-win exchange with an emphasis on the economic side, the interviewed surrogate mothers talked about surrogacy as creative labour of giving life. In Russia, approaches to surrogacy among the interviewed surrogate mothers, professionals and intended parents overlapped in framing it as work and a businesslike commodity exchange. We suggest these three different ways of ethical reasoning about the clinical labour of surrogacy, including justifications of women's incorporation into this labour, were situated in local moral frameworks. We name them "repro-regional moral frameworks", inspired by earlier work on moral frameworks as well as on reproductive nationalisms and transnational reproduction. Building on these findings, we argue that any international or global regulation of surrogacy, or indeed any moral stance on it, needs to take these local differences into account.

RESUMEN

Global reproductive landscapes and with them cross-border routes are rapidly changing. This paper examines the reproductive routes and choices of fertility travellers from China to Russia as reported by medical professionals and fertility service providers. Providing new empirical data, it raises new ethical questions on the facilitation of cross-border reproductive travel and the commercialisation of reproductive treatment. The relaxation of the one-child policy in 2014 in China, the increasing demand for ART exceeding the capacity of national fertility clinics and the difficulty of accessing treatment with donor eggs concomitant with a growing economic power of the upper-middle class are shaping the ART industry in Asia in new ways. A new development is Chinese citizens increasingly seeking ART treatment in Russia, which has a long-standing practice of ART governed by a liberal legislation. Furthermore, as China prohibits the export of gametes, Chinese fertility travellers rely on acquiring donor gametes once starting treatment abroad. Clinicians in Russia report three strategies amongst their Chinese patients: One group is using donor eggs of women of Asian appearance living in Russia or is hiring women of resembling appearance from third-party countries to donate their eggs in Russia to create resemblance in their offspring. Another group is buying white donor gametes to create Eurasian mixed children and thus 'enhance' their offspring. Providing novel empirical data, this article informs ethical deliberation and raises imminent questions for further research in this understudied geographic region and on cross-border reproductive treatment.

RESUMEN

BACKGROUND: Bacterial screening of all produced platelet concentrates (PCs) is implemented in many countries to reduce the risk of transfusion-transmitted sepsis. This study compares three rapid bacterial detection methods by imitating real-life conditions. STUDY DESIGN AND METHODS: The sensitivity of a solid-phase scanning cytometer (optimized Scansystem, Hemosystem), fluorescence-activated cell sorting (FACS) analysis, and 16S RNA in-house nucleic acid testing (NAT) was evaluated by spiking PCs with four transfusion relevant bacteria (Staphylococcus aureus, Bacillus cereus, Klebsiella pneumoniae, and Escherichia coli ). Two different inocula (10 colony-forming units [CFUs]/mL and 10 CFUs/bag) were used to simulate real-life conditions. Samples were taken at 12, 16, 20, and 24 hours after spiking. RESULTS: With the high inoculum, NAT had a 100 percent rate of positive testing for all four types of bacteria (10/10 replicates) at each time point. With the exception of E. coli, the sensitivity of FACS and optimized Scansystem was comparable for the high inoculum. With the low inoculum, 60 percent of E. coli, 80 percent of B. cereus, 90 percent of K. pneumoniae, and 100 percent of S. aureus were NAT-positive 12 hours after spiking. In contrast, only 20 percent of E. coli, 10 percent of B. cereus, and 70 percent of K. pneumoniae were FACS-positive with the low inoculum 12 hours after spiking. CONCLUSIONS: In summary, the preliminary data revealed a higher sensitivity for NAT in comparison to FACS and optimized Scansystem under the defined study conditions. To imitate real-life conditions, further spiking studies with a low inoculum (10 CFUs/bag) and slower growing organisms should be conducted to examine the sensitivity of available detection systems.

RESUMEN

BACKGROUND AND OBJECTIVES: The prevention and detection of bacterial contamination of platelet concentrates remains a major challenge for transfusion medicine. To be suitable for blood-transfusion services, the contamination detection method must be highly sensitive, easy to perform and preferably of low cost. In this spiking study, we evaluated the new optimized Scansystem Platelet Kit detection method for use on apheresis platelets. STUDY DESIGN AND METHODS: Apheresis platelet concentrates (APCs) were individually spiked with 10 colony-forming units (CFU)/ml of one of 10 different strains of bacteria. The spiked APCs were analysed at specific time-points during incubation by using the optimized Scansystem Platelet Kit. Bacterial enumeration was performed by plating onto blood agar. RESULTS: All the bacterial strains tested were detected by using the optimized Scansystem Platelet Kit when sampled 24 h after spiking. Compared to the Scansystem standard kit, sensitivity was increased to < 50 CFU/ml. The identity of the spiked bacteria was confirmed by Gram staining and DNA fingerprinting. CONCLUSION: The optimized Scansystem Platelet Kit was able to reliably detect, within 70 min, 10 transfusion-relevant bacterial species in APCs when a sample volume was taken 24 h after spiking. This is the first study carried out by using the optimized Scansystem bacterial detection that was found to have an enhanced sensitivity compared to the standard kit.
