The ‘Institutional Lottery’: institutional variation in the processes involved in accessing late abortion in Victoria, Australia
Despite abortion being decriminalised in Victoria, Australia, access remains difficult, especially at later gestations. Institutions (i.e. health services) place restrictions on the availability of late abortions and/or require additional requirements to be satisfied (e.g. Hospital Termination Review Committee approval), as a consequence of local regulation (i.e. policies and processes determined at the institutional level). This paper reports on the results of 27 interviews with Victorian health professionals about late abortion processes and the operation of Termination Review Committees in Victorian health services, which were analysed thematically. The results reveal the operation of an ‘institutional lottery’ whereby patients' experiences in seeking late abortion services were variable and largely shaped by the institution(s) they found themselves in
31st Annual Meeting and Associated Programs of the Society for Immunotherapy of Cancer (SITC 2016) : part two
Background
The immunological escape of tumors represents one of the main ob- stacles to the treatment of malignancies. The blockade of PD-1 or CTLA-4 receptors represented a milestone in the history of immunotherapy. However, immune checkpoint inhibitors seem to be effective in specific cohorts of patients. It has been proposed that their efficacy relies on the presence of an immunological response. Thus, we hypothesized that disruption of the PD-L1/PD-1 axis would synergize with our oncolytic vaccine platform PeptiCRAd.
Methods
We used murine B16OVA in vivo tumor models and flow cytometry analysis to investigate the immunological background.
Results
First, we found that high-burden B16OVA tumors were refractory to combination immunotherapy. However, with a more aggressive schedule, tumors with a lower burden were more susceptible to the combination of PeptiCRAd and PD-L1 blockade. The therapy signifi- cantly increased the median survival of mice (Fig. 7). Interestingly, the reduced growth of contralaterally injected B16F10 cells sug- gested the presence of a long lasting immunological memory also against non-targeted antigens. Concerning the functional state of tumor infiltrating lymphocytes (TILs), we found that all the immune therapies would enhance the percentage of activated (PD-1pos TIM- 3neg) T lymphocytes and reduce the amount of exhausted (PD-1pos TIM-3pos) cells compared to placebo. As expected, we found that PeptiCRAd monotherapy could increase the number of antigen spe- cific CD8+ T cells compared to other treatments. However, only the combination with PD-L1 blockade could significantly increase the ra- tio between activated and exhausted pentamer positive cells (p= 0.0058), suggesting that by disrupting the PD-1/PD-L1 axis we could decrease the amount of dysfunctional antigen specific T cells. We ob- served that the anatomical location deeply influenced the state of CD4+ and CD8+ T lymphocytes. In fact, TIM-3 expression was in- creased by 2 fold on TILs compared to splenic and lymphoid T cells. In the CD8+ compartment, the expression of PD-1 on the surface seemed to be restricted to the tumor micro-environment, while CD4 + T cells had a high expression of PD-1 also in lymphoid organs. Interestingly, we found that the levels of PD-1 were significantly higher on CD8+ T cells than on CD4+ T cells into the tumor micro- environment (p < 0.0001).
Conclusions
In conclusion, we demonstrated that the efficacy of immune check- point inhibitors might be strongly enhanced by their combination with cancer vaccines. PeptiCRAd was able to increase the number of antigen-specific T cells and PD-L1 blockade prevented their exhaus- tion, resulting in long-lasting immunological memory and increased median survival
'I haven’t had to bare my soul but now I kind of have to' : describing how voluntary assisted dying conscientious objectors anticipated approaching conversations with patients in Victoria, Australia
Background: Dealing with end of life is challenging for patients and health professionals alike. The situation becomes even more challenging when a patient requests a legally permitted medical service that a health professional is unable to provide due to a conflict of conscience. Such a scenario arises when Victorian health professionals, with a conscientious objection (CO) to voluntary assisted dying (VAD), are presented with patients who request VAD or merely ask about VAD. The Voluntary Assisted Dying Act 2017 (Vic) recognizes the inherent conflict of conscience that may arise for some health professionals when asked to provide VAD and responds by affording broad protection to conscientious objectors who wish to refuse to take part in the VAD process. Methods: Seventeen semi-structured qualitative interviews were conducted with Victorian health professionals with a self-identified CO to VAD in the lead-up to the implementation of VAD in Victoria. Interviews explored how participants anticipated they would manage their CO in practice. Interviews were transcribed verbatim and analyzed thematically. Results: Our results reveal that the way in which health professionals claimed they would approach CO conversations is variable and was dependant on the strength of their opposition to VAD. We categorized conscientious objectors according to their approach as either dissuasive non-referrers, passive non-referrers, facilitators or negotiators. Our study also explores the perceived difficulties of exercising one’s CO as identified by our participants. Conclusion: The broad protection offered by the Voluntary Assisted Dying Act 2017 (Vic) encourages a range of behaviors from conscientious objectors, due to the minimal obligations imposed. In order to assist conscientious objectors, more policy, institutional guidance, and education needs to be available to conscientious objectors explicitly addressing how to effectively manage one’s CO. Such guidance is imperative to ensuring that their moral integrity is preserved and that they are exercising their CO appropriately.</p
The Unethical Texas Heartbeat Law
Key pointsWhat is already known? The Texas Heartbeat Act, which has been in effect since September 2021, prohibits abortions once a ‘fetal heartbeat’ is detected, except in emergency situations. The law significantly limits access to abortion services in Texas, by essentially prohibiting abortions post 6 weeks' gestation. The law has been subjected to several legal challenges, none of which have been successful to date.What does this article add? This article provides an overview of some of the ethical concerns the law raises and identifies some of the problems the law creates for women, the health profession and society. The article ultimately argues that the law ought to be quashed.<br/
A narrative literature review of the impact of conscientious objection by health professionals on women’s access to abortion worldwide 2013–2021
Conscientious objection to provide abortion has been enshrined in laws and policies globally. Insufficient attention has been paid to the direct and indirect ways in which conscientious objection compromises women’s access to a lawful abortion. Using a systematic search strategy, this narrative literature review synthesises the literature exploring conscientious objection’s impact on women’s access to abortion in a range of countries. This narrative literature review builds on an extensive literature review published by Chavkin et al. (2013. Conscientious objection and refusal to provide reproductive healthcare: A white paper examining prevalence, health consequences, and policy responses. International Journal of Gynecology & Obstetrics, 123, S41–S56. https://doi.org/10.1016/S0020-7292(13)60002-8). Searches were undertaken on the Medline (Ovid), Global Health, CINAHL, Scopus and Science Direct databases. Thirty six papers were included for thematic analysis. Conscientious objection to abortion was found to impact women’s access to abortion at three main levels: the practitioner level, the healthcare system level and the sociocultural environment level. Conscientious objection was found to impact access directly through attempts by health professionals to restrict access, and indirectly by exacerbating pre-existing barriers to access. Further research is required to better quantify the extent to which this impacts women and whether interventions are effective in reducing the barriers that conscientious objection creates and exacerbates.</p
