RESUMO

Despite years of warnings by the academic community that for most of the stem cell-based therapies offered in the private arena little evidence of efficacy exists, these services have been increasingly offered by Canadian private clinics. Recently, as the culmination of years of clashes between stem cell researchers and therapy providers, Health Canada issued a statement prohibiting any type of cell therapy that is not specifically approved. In this climate of conflict, a small group representing both these communities as well as the government gathered in Vancouver to identify common values, and agree on principles to move forward constructively. This historic moment demonstrated that even in this contentious space a meeting-of-minds in between researchers, clinicians, ethicists, entrepreneurs and other stakeholders is possible.

RESUMO

Cell therapies hold significant promise for the treatment of injured or diseased musculoskeletal tissues. However, despite advances in research, there is growing concern about the increasing number of clinical centres around the world that are making unwarranted claims or are performing risky biological procedures. Such providers have been known to recommend, prescribe, or deliver so called 'stem cell' preparations without sufficient data to support their true content and efficacy. In this annotation, we outline the current environment of stem cell-based treatments and the strategies of marketing directly to consumers. We also outline the difficulties in the regulation of these clinics and make recommendations for best practice and the identification and reporting of illegitimate providers.

RESUMO

The prevalence of businesses selling autologous stem cell-based interventions to patients in Australia has raised serious concerns about how weaknesses in regulation have enabled the emergence of an industry that engages in aggressive marketing of unproven treatments to patients. Little is known about how patients experience this marketing and their subsequent interactions with practitioners. This paper reports results from 15 semistructured interviews with patients and carers, and also draws upon discussion conducted with patients, carers and family members (22 participants) in a workshop setting. We explore how Australian patients and carers understand and experience these interventions, and how their presumptions about the ethics of medical practice, and the regulatory environment in Australia have conditioned their preparedness to undergo unproven treatments.

RESUMO

BACKGROUND: Medical crowdfunding is a growing phenomenon, and newspapers are publishing on the topic. This research analyzed how illness-related crowdfunding and crowdfunding campaigns have recently been represented in newspapers that are popular in the United States and Canada. METHODS: A sample of 336 articles about medical crowdfunding published during the two year time period from October 7, 2015 to October 6, 2017 was produced using a Factiva search of the English language newspapers with the largest Canadian and United States readership. A coding frame was developed for and applied to the sample to analyze content. RESULTS: Articles portrayed crowdfunding campaigns positively (43.75%) and neutrally (47.92%), but rarely negatively (4.76%). Articles mostly mentioned the crowdfunding phenomenon with a neutral characterization (93.75%). Few (8.63%) articles mentioned ethical issues with the phenomenon of crowdfunding. Ailments most commonly precipitating the need for a campaign included cancer (49.11%) and rare disease (as stated by the article, 36.01%). Most articles (83.04%) note where donations and contributions can be made, and 59.23% included a hyperlink to an online crowdfunding campaign website. Some articles (26.49%) mentioned a specific monetary goal for the fundraising campaign. Of the 70 (20.83%) articles that indicated the treatment sought may be inefficacious, was unproven, was experimental or lacked regulatory approval, 56 (80.00%) noted where contributions can be made and 36 (51.43%) hyperlinked directly to an online crowdfunding campaign. CONCLUSIONS: Crowdfunding campaigns are portrayed positively much more often than negatively, many articles promote campaigns for unproven therapies, and links directly to crowdfunding campaign webpages are present in most articles. Overall, crowdfunding is often either implicitly or explicitly endorsed.

RESUMO

The stem cell and regenerative medicine arena has become increasingly complicated in recent years with thousands of people involved. There are as many as a dozen or more main groups of stakeholders, who together may be viewed as one ecosystem that is now rapidly evolving. The nature of the ecosystem and its evolution have major implications for not just those within it, but also for medicine and society at large. Here, I describe this ecosystem and its evolution, as well as the negative impacts within the ecosystem of a constellation of hundreds of unproven for-profit clinics and related businesses. Finally, I propose approaches for how to positively influence and drive the future of the global stem cell ecosystem.

RESUMO

An outstanding amount of resources has been used in research on manipulation of human stem cells, especially mesenchymal stem cells (MSCs), for various clinical applications. However, human MSCs have not been fully utilized in clinical applications due to restrictions with regard to their certain biosafety and bioefficacy concerns, for example, genetic abnormality, tumor formation, induction of host immune response and failure of homing and engraftment. This review summarizes the biosafety and bioefficacy assessment of human MSCs in terms of genetic stability, tumorigenicity, immunogenicity, homing and engraftment. The strategies used to reduce the biosafety concerns and improve the bioefficacy of human MSCs are highlighted. In addition, the approaches that can be implemented to improve their biosafety and bioefficacy assessment are briefly discussed.

RESUMO

Outcomes have improved considerably in multiple myeloma (MM), but disparities among racial-ethnic groups exist. Differences in utilization of novel therapeutics are likely contributing factors. We explored such differences from the SEER-Medicare database. A utilization analysis of lenalidomide, thalidomide, bortezomib, and stem cell transplant (SCT) was performed for patients diagnosed with MM between 2007 and 2009, including use over time, use by race, time-dependent trends for each racial subgroup, and survival analysis. A total of 5338 MM patients were included with median 2.4-year follow-up. Within the first year of MM diagnosis, utilization of lenalidomide, bortezomib, SCT, and more than one novel agent increased over time while utilization of thalidomide decreased. There was significantly lower utilization of lenalidomide among African-Americans (P < 0.01), higher thalidomide use among Hispanics and Asians (P < 0.01), and lower bortezomib use among Asians (P < 0.01). Hispanics had the highest median number of days to first dose of bortezomib (P = 0.02) and the lowest utilization of SCT (P < 0.01). Hispanics and Asians were the only groups without notable increases in lenalidomide and bortezomib use, respectively. SCT utilization increased over time for all except African-Americans. SCT use within the first year after diagnosis was associated with better overall survival (HR 0.52; 95% CI: 0.4-0.68), while bortezomib use was associated with inferior survival (HR 1.14; 95% CI 1.02-1.28). We noted considerable variability in MM therapeutics utilization with seeming inequity for racial-ethnic minorities. These trends should be considered to eliminate drug access and utilization disparities and achieve equitable benefit of therapeutic advances across all races.

RESUMO

Treatments based on stem cells have long been heralded for their potential to drive the future of regenerative medicine and have inspired increasing medical and business interest. The stem cell therapy market has been expanding since 2012, but earnings and profitability still lag the broader health care sector (compounded annual growth rate in annual financing of 31.5% versus 13.4%, respectively). On the basis of historical financial data, approximately $23 billion has been invested in stem cell companies since 1994, with more than 80% of this raised from 2011 through 2016. This reflects a marked acceleration in capital investment, as companies began late-stage clinical trials, initiate partnerships or are acquired by large pharmaceutical companies. All of these data reflect a field that is emerging from infancy, which will demand more time and capital to mature. This update is relevant to researchers, clinicians and investors who wish to quantify the potential in this field.

RESUMO

The global political economy of stem cell therapies is characterised by an established biomedical hegemony of expertise, governance and values in collision with an increasingly informed health consumer demand able to define and pursue its own interest. How does the hegemony then deal with the challenge from the consumer market and what does this tell us about its modus operandi? In developing a theoretical framework to answer these questions, the paper begins with an analysis of the nature of the hegemony of biomedical innovation in general, its close relationship with the research funding market, the current political modes of consumer incorporation, and the ideological role performed by bioethics as legitimating agency. Secondly, taking the case of stem cell innovation, it explores the hegemonic challenge posed by consumer demand working through the global practice based market of medical innovation, the response of the national and international institutions of science and their reassertion of the values of the orthodox model, and the supporting contribution of bioethics. Finally, the paper addresses the tensions within the hegemonic model of stem cell innovation between the key roles and values of scientist and clinician, the exacerbation of these tensions by the increasingly visible demands of health consumers, and the emergence of political compromise.

RESUMO

PURPOSE OF REVIEW: Surgical advances over the past few decades have transformed the clinical management of congenital heart disease, such as hypoplastic left heart syndrome. Congenital heart disease affects more than 1% of liveborn infants and accounts for more than 2.5 million affected children per year worldwide. The cost and availability of complex medical management for these children becomes bluntly realized when heart failure progresses and only palliative options remain. Cell-based cardiac regeneration has been the focus of intensive efforts in adult heart disease for more than a decade and now has promise for pediatrics. RECENT FINDINGS: Innate cardiac regeneration in the pediatric setting is measurable and potentially modifiable in the early stages of development. Repurposing cell-based manufactured products to promote cardiac regeneration in congenital heart disease has demonstrated significant improvement in cases of dilated cardiomyopathy and structural heart disease in infants. SUMMARY: A focus on preemptive cardiac regeneration in the pediatric setting may offer new insights into the timing of surgery, location of cell-based delivery, and type of cell-based regeneration that could further inform acquired cardiac disease applications. The concept of cell-based pediatric cardiac regenerative surgery could transform the management of congenital heart disease when cost-effective strategies produce a valuable adjunctive solution to improve outcomes of cardiac surgery.

RESUMO

This article concerns new developments in autologous adult stem cell research in Japan and India through the notions of biohierarchy and bionetworking. It conceptualizes how human subject research in one country may be turned into experimental stem cell therapies in another through bionetworks. We analyse the processes that enable researchers in Japan to discard a therapy as being of reputational risk, while researchers in India employ it so that it becomes reputation enhancing. At the same time, scientists from both countries collaborate in and potentially benefit from the same bionetwork. Explaining how the recruitment of patients and scientists is organized through bionetworking, this article analyses how experimental research in India thrives using Japanese technologies. The concept of biohierarchy illustrates how inequalities in health and standards of living in India and in Japan underpin the methods by which researchers, medical professionals, managers and patients collaborate in bionetworks. The concept of 'boundary object' here captures the ways in which the meaning of experimental therapy is defined by subjective categories projected onto it by patients and scientists alike. The article is based on fieldwork conducted by both authors during 3 months between September and December 2008 at various locations in India and Japan. Data for this article were collected from a wide range of interviews with stem cell researchers, medical doctors, coordinators, managers and patients, primary and secondary sources gathered at these centres, and through web and archival research.
