Article
Peripheral blood stem cell (PBSC) mobilisation in multiple myeloma (MM) patients after exposure to daratumumab (D), a CD38 targeting monoclonal antibody, produces a lower stem cell yield possibly due to an effect on CD34+ stem cells (Hulin et al., 2021). Similarly, the GRIFFIN study reported greater plerixafor usage to facilitate PBSC mobilisation...
Article
BACKGROUND Survival rates in multiple myeloma (MM) have significantly improved in recent decades with the advent of high-dose chemotherapy conditioned autologous stem cell transplantation (ASCT) and the availability of novel agents for induction therapy (Kumar SK et al. Blood 2008). Failure to respond to front-line bortezomib-based induction therap...

Article
Clinical uses of unproven stem cell-based interventions abound, yet many patients may be harmed by receiving them, raising complex ethical, economic, and societal concerns. Regulators, scientists, clinicians, professional societies, and patient advocacy groups need to collaboratively articulate expectations related to the proper development and del...
Article
Corruption is a word used loosely to describe many kinds of action that people find distasteful. We prefer to reserve it for the intentional misuse of the good offices of an established social entity for private benefit, posing as fair trading. The currency of corruption is not always material or financial. Moral corruption is all too familiar with...
Article
There are increasing demands on regulators and insurers internationally to provide access to medicines more quickly, and often on the basis of less robust evidence of safety, efficacy or cost-effectiveness than have traditionally been required. These demands arise from a number of sources, including those advocating for access to medicines for pati...

Article
The term innovation is frequently used as a justification for allowing clinicians to offer unproven autologous stem cell-based interventions (SCBIs) to their patients. Proponents of this kind of innovation (which we refer to as "clinical innovation") argue that physicians should be free to administer whatever interventions they choose, and informed...
Article
Background: Advance care planning (ACP) is defined in a variety of ways, although it is widely understood as a process undertaken by patients, when they have capacity, to define and communicate their treatment preferences for future care. Few studies have explored the meaning and importance patients place on their ability to participate in directi...
Article
Biobanks are increasingly being linked together into global networks in order to maximise their capacity to identify causes of and treatments for disease. While there is great optimism about the potential of these biobank networks to contribute to personalised and data-driven medicine, there are also ethical concerns about, among other things, risk...
Article
Non-financial interests, and the conflicts of interest that may result from them, are frequently overlooked in biomedicine. This is partly due to the complex and varied nature of these interests, and the limited evidence available regarding their prevalence and impact on biomedical research and clinical practice.
