    Humoral immune response to COVID-19 mRNA vaccines in patients with relapsing multiple sclerosis treated with ofatumumab

    BACKGROUND: There are limited data available regarding the impact of ofatumumab, an anti-CD20 B-cell-depleting monoclonal antibody for relapsing multiple sclerosis (RMS), on vaccination response. The study objective was to assess humoral immune response (HIR) to non-live coronavirus disease 2019 (COVID-19) messenger RNA (mRNA) vaccination in patients with RMS treated with ofatumumab. METHODS: This was an open-label, single-arm, multicenter, prospective pilot study of patients with RMS aged 18-55 years who received 2 or 3 doses of a COVID-19 mRNA vaccine after ≄1 month of subcutaneous ofatumumab (20 mg/month) treatment. The primary endpoint was the proportion of patients achieving HIR, as defined by local laboratory severe acute respiratory syndrome coronavirus-2 qualitative immunoglobulin G assays. Assay No. 1 was ≄14 days after the second or third vaccine dose. Assay No. 2 was 90 days thereafter. RESULTS: Of the 26 patients enrolled (median [range] age: 42 [27-54] years; median [range] ofatumumab treatment duration: 237 [50-364] days), HIR was achieved by 53.9% (14/26; 95% CI: 33.4 - 73.4%) at Assay No. 1 and 50.0% (13/26; 95% CI: 29.9 - 70.1%) at Assay No. 2. Patients who received 3 vaccine doses had higher HIR rates (Assay No. 1: 70.0% [7/10]; Assay No. 2: 77.8% [7/9]) than those who received 2 doses (Assay No. 1: 46.7% [7/15]; Assay No. 2: 42.9% [6/14]). Of patients aged \u3c40 years without previous anti-CD20 therapy, HIR was achieved by 90.0% (9/10) at Assay No. 1 and 75.0% (6/8) at Assay No. 2. No serious adverse events were reported. CONCLUSION: Patients with RMS treated with ofatumumab can mount HIRs following COVID-19 vaccination. A plain language summary, infographic and a short video summarizing the key results are provided in supplementary material.

    Self-organization in the olfactory system: one shot odor recognition in insects

    We show in a model of spiking neurons that synaptic plasticity in the mushroom bodies in combination with the general fan-in, fan-out properties of the early processing layers of the olfactory system might be sufficient to account for its efficient recognition of odors. For a large variety of initial conditions the model system consistently finds a working solution without any fine-tuning, and is, therefore, inherently robust. We demonstrate that gain control through the known feedforward inhibition of lateral horn interneurons increases the capacity of the system but is not essential for its general function. We also predict an upper limit for the number of odor classes Drosophila can discriminate based on the number and connectivity of its olfactory neurons

    Physician-assisted suicide: a review of the literature concerning practical and clinical implications for UK doctors

    Get PDF
    BACKGROUND: A bill to legalize physician-assisted suicide in the UK recently made significant progress in the British House of Lords and will be reintroduced in the future. Until now there has been little discussion of the clinical implications of physician-assisted suicide for the UK. This paper describes problematical issues that became apparent from a review of the medical and psychiatric literature as to the potential effects of legalized physician-assisted suicide. DISCUSSION: Most deaths by physician-assisted suicide are likely to occur for the illness of cancer and in the elderly. GPs will deal with most requests for assisted suicide. The UK is likely to have proportionately more PAS deaths than Oregon due to the bill's wider application to individuals with more severe physical disabilities. Evidence from other countries has shown that coercion and unconscious motivations on the part of patients and doctors in the form of transference and countertransference contribute to the misapplication of physician-assisted suicide. Depression influences requests for hastened death in terminally ill patients, but is often under-recognized or dismissed by doctors, some of whom proceed with assisted death anyway. Psychiatric evaluations, though helpful, do not solve these problems. Safeguards that are incorporated into physician-assisted suicide criteria probably decrease but do not prevent its misapplication. SUMMARY: The UK is likely to face significant clinical problems arising from physician-assisted suicide if it is legalized. Terminally ill patients with mental illness, especially depression, are particularly vulnerable to the misapplication of physician-assisted suicide despite guidelines and safeguards

    The role of private pesticide vendors in preventing access to pesticides for self-poisoning in rural Sri Lanka

    Get PDF
    In 15% to 20% of self-poisoning cases, the pesticides used are purchased from shops just prior to ingestion. We explored how pesticide vendors interacted with customers at risk of self-poisoning to identify interventions to prevent such poisonings. Two strategies were specifically discussed: selling pesticides only to farmers bearing identity cards or customers bearing pesticide ‘prescriptions’. Vendors reported refusing to sell pesticides to people thought to be at risk of self-poisoning, but acknowledged the difficulty of distinguishing them from legitimate customers; vendors also stated they did want to help to improve identification of such customers. The community did not blame vendors when pesticides used for self-poison were purchased from their shops. Vendors have already taken steps to restrict access, including selling low toxic products, counselling and asking customer to return the next day. However, there was little support for the proposed interventions of ‘identity cards’ and ‘prescriptions’. Novel public health approaches are required to complement this approach

    Collaborative Care for patients with severe borderline and NOS personality disorders: A comparative multiple case study on processes and outcomes

    <p>Abstract</p> <p>Background</p> <p>Structured psychotherapy is recommended as the preferred treatment of personality disorders. A substantial group of patients, however, has no access to these therapies or does not benefit. For those patients who have no (longer) access to psychotherapy a Collaborative Care Program (CCP) is developed. Collaborative Care originated in somatic health care to increase shared decision making and to enhance self management skills of chronic patients.

The aim of the CCP is to improve quality of life and self management skills, and reduce destructive behaviour and other manifestations of the personality disorder.</p> <p>Methods/design</p> <p>Quantitative and qualitative data are combined in a comparative multiple case study. This makes it possible to test the feasibility of the CCP, and also provides insight into the preliminary outcomes of CCP.

The perspectives of patients, their informal carers and nurses are integrated in this study. Data (questionnaires, documents, and interviews) will be collected among these three groups of participants. The process of treatment and care within both research conditions is described with qualitative research methods.
