We enrolled 23 patients with relapsed follicular lymphoma (FL) in a prospective single-arm study of auto-SCT combined with in vivo rituximab graft purging and post transplant rituximab maintenance. Minimal residual disease was monitored with quantitative PCR testing. With a median follow-up of 74.2 months, neither median overall survival (OS) nor PFS has been reached. Here, 5-year OS and 5-year PFS are 78% (95% confidence interval (CI) 61-95%) and 59% (95% CI 38-80%), respectively. Time to progression (TTP) with the experimental regimen was significantly improved compared with TTP with the last prior treatment (Po0.001). Durable molecular remissions occurred in 11 of 13 assessable patients. PFS was significantly longer in patients who achieved a molecular remission by 3 months post-auto-SCT (P ¼ 0.001). Prolonged hypogammaglobulinemia occurred in most patients; however, no increase in major infections was observed.

SummaryThe Scaling-up Health-Arts Programme: Implementation and Effectiveness Research (SHAPER) project is the world's largest hybrid study on the impact of the arts on mental health embedded into a national healthcare system. This programme, funded by the Wellcome Trust, aims to study the impact and the scalability of the arts as an intervention for mental health. The programme will be delivered by a team of clinicians, research scientists, charities, artists, patients and healthcare professionals in the UK's National Health Service (NHS) and the community, spanning academia, the NHS and the charity sector. SHAPER consists of three studies – Melodies for Mums, Dance for Parkinson's, and Stroke Odysseys – which will recruit over 800 participants, deliver the interventions and draw conclusions on their clinical impact, implementation effectiveness and cost-effectiveness. We hope that this work will inspire organisations and commissioners in the NHS and around the world to expand the remit of social prescribing to include evidence-based arts interventions.

Molecular remission in the autograft and bone marrow after transplant are predictive of durable clinical remission in relapsed follicular lymphoma. Thus, a simple reliable method to quantify minimal residual disease (MRD) would improve prognostication in these patients. Fluorescent hybridization probes have been used in real-time quantitative polymerase chain reaction (RQ-PCR) to monitor MRD with a reproducible sensitivity of 0.01%; however, these techniques are expensive and require additional experiments to examine clonality. We describe a SYBR Green I detection method that is more universal, checks clonal identity, yields the same sensitivity for monitoring MRD, and is more economically attractive. Using this method to follow 14 follicular lymphoma patients treated with autologous stem cell transplantation, molecular markers were successfully defined for 12 patients. Median contamination of stem-cell grafts was 0.1% (range, 0 to 13%). Six patients with measurable graft contamination became PCR-negative in blood and bone marrow within 12 months after autologous stem cell transplantation. Three patients free of disease progression (median follow-up of 75 months) are in molecular remission. Increasing fractions of RQ-PCR-positive blood and bone marrow cells reliably predicted morphological and clinical relapse. In one case, both clinical relapse and spontaneous regression were reflected by changes in MRD levels. Thus, our RQ-PCR method reproducibly distinguishes different levels of MRD. (J

Background Postnatal depression (PND) affects 13% of new mothers, with numbers rising during the COVID-19 pandemic. Despite this prevalence, many women have difficulty with or hesitancy towards accessing pharmacological and/or psychological interventions. Group-based mother-baby activities, however, have a good uptake, with singing improving maternal mental health and the mother-infant relationship. The recent lockdowns highlight the importance of adapting activities to an online platform that is wide-reaching and accessible. Aims The SHAPER-PNDO study will primarily analyse the feasibility of a 6-week online singing intervention, Melodies for Mums (M4M), for mothers with PND who are experiencing barriers to treatment. The secondary aim of the SHAPER-PNDO study will be to analyse the clinical efficacy of the 6-week M4M intervention for symptoms of postnatal depression. Methods A total of 120 mothers and their babies will be recruited for this single-arm study. All dyads will attend 6 weekly online singing sessions, facilitated by Breathe Arts Health Research. Assessments will be conducted on Zoom at baseline and week 6, with follow-ups at weeks 16 and 32, and will contain interviews for demographics, mental health, and social circumstances, and biological samples will be taken for stress markers. Qualitative interviews will be undertaken to understand the experiences of women attending the sessions and the facilitators delivering them. Finally, data will be collected on recruitment, study uptake and attendance of the programme, participant retention, and acceptability of the intervention. Discussion The SHAPER-PNDO study will focus on the feasibility, alongside the clinical efficacy, of an online delivery of M4M, available to all mothers with PND. We hope to provide a more accessible, effective treatment option for mothers with PND that can be available both during and outside of the pandemic for mothers who would otherwise struggle to attend in-person sessions, as well as to prepare for a subsequent hybrid RCT. Trial registration ClinicalTrials.gov Identifier: NCT04857593. Registered retrospectively on 22 April 2021. The first participants were recruited on 27 January 2021, and the trial is ongoing.
