Talking about abortion online: A qualitative exploration of how and why women use the Internet to seek social support around abortion

Background: Despite its frequent occurrence, abortion remains stigmatised. Abortions are often concealed from social network members, which may as a result limit access to social support during what is - for some - a difficult experience. Online spaces have previously been shown to be valuable resources for seeking healthcare-related information, and also for support in managing stigmatising experiences. While there has been previous academic exploration of the content within online abortion accounts themselves, little is known about why women engage with and share abortion-related content online, how they access and navigate these online spaces, and how these experiences may shape their understanding of their abortion, which my research sought to address. Using key sociological concepts of stigma, social support, and personal disclosure (henceforth referred to in this thesis as ‘sharing’), the research presented in this thesis sought to explore how these concepts relate to each other to inform the motivations of women to go online seeking abortion-related content and their experiences therein. Methods: To answer the research questions posed in this thesis, which sought detailed accounts of how and why women used online spaces in relation to abortion accounts online, qualitative methodologies informed by feminist research practice were used. Twenty-three women living in Scotland (aged 20- 54) were recruited in the summer of 2020 through social media and online advertisements, and participated in in-depth, semi-structured interviews online or by telephone. Of the sample, all participants reported reading and exploring others’ abortion-related content online, with ten women reporting that in addition to this activity they too shared their own abortion experience online. Interviews focused on use of online spaces containing abortion-related content and their experiences of their abortion(s) more broadly. The data were analysed using reflexive thematic analysis. Findings: My analysis suggests that stigma and social support were significant factors in the decision to use online spaces to explore abortion-related content, and the supportive and stigmatising experiences that they reported online substantially shaped their perception of their own abortion(s) and abortion more broadly. The avoidance of stigmatising interactions with in-person social network members, and the possibility of accessing otherwise unavailable social support, were primary drivers for participants to view, interact with, and share abortionrelated content. Finding what they viewed as relevant and supportive online content was not straightforward, with the onus of finding this content constituting an additional burden at what was already a potentially challenging time. Participants had to navigate towards online spaces within which they felt comfortable engaging, considering ‘affordances’ of anonymity, visibility, and control. Online support was perceived to be available via both one-way and twoway pathways, with participants valuing the availability of abortion accounts in these online spaces and the opportunity to interact further with that content, should they wish to do so. Concurrently, abortion stigma was prevalent online, significantly shaping participants’ experiences, their willingness to engage or share further, and their thoughts about their abortion more broadly. Conclusions: This thesis frames stigma and social support as interconnected factors impacting women’s experiences of exploring abortion-related content online. My findings suggest that online spaces can be both an opportunity to have supportive engagement with others who have had an abortion experience, addressing a perceived gap from in-person resources, and concurrently expose women to abortion stigma and harassment, which in many cases is what they sought to avoid in the first place. Signposting towards well-moderated and trusted online resources would be beneficial in limiting exposure to anti-abortion sentiment online while allowing women to access spaces in which to read and interact with others’ abortion accounts

Seeking support for abortion online: a qualitative study of women’s experiences

Introduction: Social support can mitigate the impact of stress and stigma before or after an abortion. However, stigma anticipation can limit access to in-person support. Informal online spaces can offer opportunities to address unmet support needs including supplementing in-person support lacking within stigmatised contexts. While earlier studies have explored content of posts comprising personal accounts of abortion, little is known about the nuances of how and to what end online spaces are navigated. Methods: Semi-structured interviews were conducted remotely (online or by telephone) with 23 women living in Scotland (aged 20–54 years) recruited through social media and online advertisements. Reflexive thematic analysis was supported by NVivo12 software. Results: Key themes: obtaining support that was unavailable from in-person networks; preparation for abortion; reducing feelings of isolation. The majority of participants independently searched online for accounts of abortion, with only three receiving any signposting to specific resources. Without guidance, finding relevant, supportive content was not straightforward. The search process was additionally complicated by the prevalence of abortion stigma online, which generated an additional burden at a potentially challenging time. Those who received direction towards particular resources reported primarily positive online experiences. Conclusions: While online content could address perceived in-person support gaps, the process of finding supportive content without guidance can be complex. Online searching may also expose women to stigmatising material and interactions. Signposting by abortion services towards well-moderated and trustworthy online resources could be constructive in limiting exposure to stigma and misinformation, while allowing those seeking it to access better support

Complementary light scattering and synchrotron small-angle X-ray scattering studies of the micelle-to-unimer transition of polysulfobetaines

YesAB and ABA di- and triblock copolymers where A is the hydrophilic poly(oligoethylene glycol methacrylate) (POEGMA) block and B is a thermo-responsive sulfobetaine block [2-(methacryloyloxy) ethyl] dimethyl-(3-sulfopropyl) ammonium hydroxide (PDMAPS) were synthesised by aqueous RAFT polymerisation with narrow dispersity (ĐM ≤ 1.22), as judged by aqueous SEC analysis. The di- and triblock copolymers self-assembled in salt-free water to form micelles with a PDMAPS core and the self-assembly of these polymers was explored by SLS and TEM analysis. The micelles were shown, by DLS analysis, to undergo a micelle-to-unimer transition at a critical temperature, which was dependent upon the length of the POEGMA block. Increasing the length of the third, POEGMA, block decreased the temperature at which the micelle-to-unimer transition occurred as a result of the increased hydrophilicity of the polymer. The dissociation of the micelles was further studied by SLS and synchrotron SAXS. SAXS analysis revealed that the micelle dissociation began at temperatures below that indicated by DLS analysis and that both micelles and unimers coexist. This highlights the importance of using multiple complementary techniques in the analysis of self-assembled structures. In addition the micelle-to-unimer morphology transition was employed to encapsulate and release a hydrophobic dye, Nile Red, as shown by fluorescence spectroscopy.Engineering and Physical Sciences Research Council (EPSRC), University of Warwic

Costs and staffing resource requirements for adaptive clinical trials: quantitative and qualitative results from the Costing Adaptive Trials project.

BACKGROUND: Adaptive designs offer great promise in improving the efficiency and patient-benefit of clinical trials. An important barrier to further increased use is a lack of understanding about which additional resources are required to conduct a high-quality adaptive clinical trial, compared to a traditional fixed design. The Costing Adaptive Trials (CAT) project investigated which additional resources may be required to support adaptive trials. METHODS: We conducted a mock costing exercise amongst seven Clinical Trials Units (CTUs) in the UK. Five scenarios were developed, derived from funded clinical trials, where a non-adaptive version and an adaptive version were described. Each scenario represented a different type of adaptive design. CTU staff were asked to provide the costs and staff time they estimated would be needed to support the trial, categorised into specified areas (e.g. statistics, data management, trial management). This was calculated separately for the non-adaptive and adaptive version of the trial, allowing paired comparisons. Interviews with 10 CTU staff who had completed the costing exercise were conducted by qualitative researchers to explore reasons for similarities and differences. RESULTS: Estimated resources associated with conducting an adaptive trial were always (moderately) higher than for the non-adaptive equivalent. The median increase was between 2 and 4% for all scenarios, except for sample size re-estimation which was 26.5% (as the adaptive design could lead to a lengthened study period). The highest increase was for statistical staff, with lower increases for data management and trial management staff. The percentage increase in resources varied across different CTUs. The interviews identified possible explanations for differences, including (1) experience in adaptive trials, (2) the complexity of the non-adaptive and adaptive design, and (3) the extent of non-trial specific core infrastructure funding the CTU had. CONCLUSIONS: This work sheds light on additional resources required to adequately support a high-quality adaptive trial. The percentage increase in costs for supporting an adaptive trial was generally modest and should not be a barrier to adaptive designs being cost-effective to use in practice. Informed by the results of this research, guidance for investigators and funders will be developed on appropriately resourcing adaptive trials

Testing the cognitive-behavioural maintenance models across DSM-5 bulimic-type eating disorder diagnostic groups: A multi-centre study

The original cognitive-behavioural (CB) model of bulimia nervosa, which provided the basis for the widely used CB therapy, proposed that specific dysfunctional cognitions and behaviours maintain the disorder. However, amongst treatment completers, only 40–50 % have a full and lasting response. The enhanced CB model (CB-E), upon which the enhanced version of the CB treatment was based, extended the original approach by including four additional maintenance factors. This study evaluated and compared both CB models in a large clinical treatment seeking sample (N = 679), applying both DSM-IV and DSM-5 criteria for bulimic-type eating disorders. Application of the DSM-5 criteria reduced the number of cases of DSM-IV bulimic-type eating disorders not otherwise specified to 29.6 %. Structural equation modelling analysis indicated that (a) although both models provided a good fit to the data, the CB-E model accounted for a greater proportion of variance in eating-disordered behaviours than the original one, (b) interpersonal problems, clinical perfectionism and low self-esteem were indirectly associated with dietary restraint through over-evaluation of shape and weight, (c) interpersonal problems and mood intolerance were directly linked to binge eating, whereas restraint only indirectly affected binge eating through mood intolerance, suggesting that factors other than restraint may play a more critical role in the maintenance of binge eating. In terms of strength of the associations, differences across DSM-5 bulimic-type eating disorder diagnostic groups were not observed. The results are discussed with reference to theory and research, including neurobiological findings and recent hypotheses

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy

Global warming and recurrent mass bleaching of corals

During 2015–2016, record temperatures triggered a pan-tropical episode of coral bleaching, the third global-scale event since mass bleaching was first documented in the 1980s. Here we examine how and why the severity of recurrent major bleaching events has varied at multiple scales, using aerial and underwater surveys of Australian reefs combined with satellite-derived sea surface temperatures. The distinctive geographic footprints of recurrent bleaching on the Great Barrier Reef in 1998, 2002 and 2016 were determined by the spatial pattern of sea temperatures in each year. Water quality and fishing pressure had minimal effect on the unprecedented bleaching in 2016, suggesting that local protection of reefs affords little or no resistance to extreme heat. Similarly, past exposure to bleaching in 1998 and 2002 did not lessen the severity of bleaching in 2016. Consequently, immediate global action to curb future warming is essential to secure a future for coral reefs

Allele-Specific HLA Loss and Immune Escape in Lung Cancer Evolution

Immune evasion is a hallmark of cancer. Losing the ability to present neoantigens through human leukocyte antigen (HLA) loss may facilitate immune evasion. However, the polymorphic nature of the locus has precluded accurate HLA copy-number analysis. Here, we present loss of heterozygosity in human leukocyte antigen (LOHHLA), a computational tool to determine HLA allele-specific copy number from sequencing data. Using LOHHLA, we find that HLA LOH occurs in 40% of non-small-cell lung cancers (NSCLCs) and is associated with a high subclonal neoantigen burden, APOBEC-mediated mutagenesis, upregulation of cytolytic activity, and PD-L1 positivity. The focal nature of HLA LOH alterations, their subclonal frequencies, enrichment in metastatic sites, and occurrence as parallel events suggests that HLA LOH is an immune escape mechanism that is subject to strong microenvironmental selection pressures later in tumor evolution. Characterizing HLA LOH with LOHHLA refines neoantigen prediction and may have implications for our understanding of resistance mechanisms and immunotherapeutic approaches targeting neoantigens. Video Abstract [Figure presented] Development of the bioinformatics tool LOHHLA allows precise measurement of allele-specific HLA copy number, improves the accuracy in neoantigen prediction, and uncovers insights into how immune escape contributes to tumor evolution in non-small-cell lung cancer

Phylogenetic ctDNA analysis depicts early-stage lung cancer evolution.

The early detection of relapse following primary surgery for non-small-cell lung cancer and the characterization of emerging subclones, which seed metastatic sites, might offer new therapeutic approaches for limiting tumour recurrence. The ability to track the evolutionary dynamics of early-stage lung cancer non-invasively in circulating tumour DNA (ctDNA) has not yet been demonstrated. Here we use a tumour-specific phylogenetic approach to profile the ctDNA of the first 100 TRACERx (Tracking Non-Small-Cell Lung Cancer Evolution Through Therapy (Rx)) study participants, including one patient who was also recruited to the PEACE (Posthumous Evaluation of Advanced Cancer Environment) post-mortem study. We identify independent predictors of ctDNA release and analyse the tumour-volume detection limit. Through blinded profiling of postoperative plasma, we observe evidence of adjuvant chemotherapy resistance and identify patients who are very likely to experience recurrence of their lung cancer. Finally, we show that phylogenetic ctDNA profiling tracks the subclonal nature of lung cancer relapse and metastasis, providing a new approach for ctDNA-driven therapeutic studies
