The capacity to designate a surrogate (CDS) is not simply another kind of medical decision-making capacity (DMC). A patient with DMC can express a preference, understand information relevant to that choice, appreciate the significance of that information for their clinical condition, and reason about their choice in light of their goals and values. In contrast, a patient can possess the CDS even if they cannot appreciate their condition or reason about the relative risks and benefits of their options. Patients who lack DMC for many or most kinds of medical choices may nonetheless possess the CDS, particularly since the complex means-ends reasoning required by DMC is one of the first capacities to be lost in progressive cognitive diseases (eg, Alzheimer's disease). That is, patients with significant cognitive decline or mental illness may still understand what a surrogate does, express a preference about a potential surrogate, and be able to provide some kind of justification for that selection. Moreover, there are many legitimate and relevant rationales for surrogate selection that are inconsistent with the reasoning criterion of DMC. Unfortunately, many patients are prevented from designating a surrogate if they are judged to lack DMC. When such patients possess the CDS, this practice is ethically wrong, legally dubious and imposes avoidable burdens on healthcare institutions.Madison Kilbride recently argued that insurance (eg, Centers for Medicare & Medicaid Services (CMS)) should cover in vitro fertilisation with preimplantation genetic testing (IVF-PGT) services for couples at high risk of having a child affected with a genetic condition. She argues that IVF-PGT meets CMS's definition of 'medically necessary care', where such care includes 'services or supplies needed to diagnose or treat an illness, injury, condition, disease or its symptoms'. Kilbride argues that IVF-PGT satisfies this definition in two ways as a diagnostic tool and as a treatment. Contradicting Kilbride, however, I argue that IVF-PGT provides neither diagnosis nor treatment under CMS's definition. Thus, as long as we accept CMS's definition of medically necessary care-which Kilbride does, explicitly-it follows that IVF-PGT does not count as medically necessary care. Still, there may be other reasons to conclude that IVF-Preimplantation genetic testing should be covered, and so, it would be a mistake to reject Kilbride's conclusion altogether. The problem is simply that Kilbride's argument-that the procedure should be covered because it is medically necessary per CMS's definition-is not sound. I conclude by discussing a number of other genetic services that are not currently being covered despite the fact that (unlike IVF-PGT) they do seem to satisfy CMS's definition of 'medically necessary diagnosis or treatment'. These services, I argue, should be provided under CMS before we consider expanding coverage to include elective procedures such as IVF-PGT.Epistemic injustice is a kind of injustice that arises when one's capacity as an epistemic subject (eg, a knower, a reasoner) is wrongfully denied. In recent years it has been argued that psychiatric patients are often harmed in their capacity as knowers and suffer from various forms of epistemic injustice that they encounter in psychiatric services. Acknowledging that epistemic injustice is a multifaceted problem in psychiatry calls for an adequate response. In this paper I argue that, given that psychiatric patients deserve epistemic respect and have a certain epistemic privilege, healthcare professionals have a pro tanto epistemic duty to attend to and/or solicit reports of patients' first-person experiences in order to prevent epistemic losses. I discuss the nature and scope of this epistemic duty and point to one interesting consequence. In order to prevent epistemic losses, healthcare professionals may need to provide some patients with resources and tools for expressing their experiences and first-person knowledge, such as those that have been developed within the phenomenological approach. I discuss the risk of secondary testimonial and hermeneutical injustice that the practice of relying on such external tools might pose and survey some ways to mitigate it.Many high-risk medical devices earn US marketing approval based on limited premarket clinical evaluation that leaves important questions unanswered. Rigorous postmarket surveillance includes registries that actively collect and maintain information defined by individual patient exposures to particular devices. Several prominent registries for cardiovascular devices require enrolment as a condition of reimbursement for the implant procedure, without informed consent. In this article, we focus on whether these registries, separate from their legal requirements, have an ethical obligation to obtain informed consent from enrolees, what is lost in not doing so, and the ways in which seeking and obtaining consent might strengthen postmarket surveillance in the USA.Statins are widely used in the treatment of hypercholesterolemia. Muscle weakness and elevated creatine kinase (CK) are frequent side effects of statins with an incidence of about 15%. click here Statin-associated myopathy is more common in people who receive multiple drugs, the elderly or women but the mechanism underlying it is still unclear. These symptoms generally improve after drug discontinuation. However, there is a type of autoimmune mediated myopathy characterised by the persistence of muscle weakness and CK elevation after stopping statins. Herein, we discuss a case of autoimmune myopathy associated with statin exposure and responsive to immunossupresive drugs. The increased use of statins in recent years raises the importance of acquaintance with this disease in clinical practice.
To estimate the risk of progressive multifocal leukoencephalopathy (PML) and the safety of natalizumab administration in patients with relapsing-remitting multiple sclerosis (RRMS).

A descriptive retrospective observational study including all patients with RRMS treated with natalizumab followed-up after 10 years.The likelihood of developing PML was estimated based on three risk factors anti-John Cunningham virus antibody index, previous immunosuppressive therapy, and duration of treatment. Patients were classified into five categories minimum probability (<0.1/1000); low (0.1/1000); medium-low (0.2-0.6/1000); medium-high (0.8-3/1000); high probability (3-10/1000).

34 patients were included. The probability of PML in the last cycle was 55.9% minimum, 8.8% low, 11.8% medium-low, 3% medium-high, and 20.5% high. 12 patients continue with active treatment with natalizumab. No cases of PML have been confirmed. Adverse effects were detected in 50% of patients.

Quantifying risk factors allows us to estimate the probability of PML appearance, thus assessing the maintenance or suspension of natalizumab.
