Management of adults and children receiving CAR T-cell therapy: 2021 best practice recommendations of the European Society for Blood and Marrow Transplantation (EBMT) and the Joint Accreditation Committee of ISCT and EBMT (JACIE) and the European Haematology Association (EHA)

BACKGROUND

Several commercial and academic autologous chimeric antigen receptor T-cell (CAR-T) products targeting CD19 have been approved in Europe for relapsed/refractory B-cell acute lymphoblastic leukemia, high-grade B-cell lymphoma and mantle cell lymphoma. Products for other diseases such as multiple myeloma and follicular lymphoma are likely to be approved by the European Medicines Agency in the near future.

DESIGN

The European Society for Blood and Marrow Transplantation (EBMT)-Joint Accreditation Committee of ISCT and EBMT (JACIE) and the European Haematology Association collaborated to draft best practice recommendations based on the current literature to support health care professionals in delivering consistent, high-quality care in this rapidly moving field.

RESULTS

Thirty-six CAR-T experts (medical, nursing, pharmacy/laboratory) assembled to draft recommendations to cover all aspects of CAR-T patient care and supply chain management, from patient selection to long-term follow-up, post-authorisation safety surveillance and regulatory issues.

CONCLUSIONS

We provide practical, clinically relevant recommendations on the use of these high-cost, logistically complex therapies for haematologists/oncologists, nurses and other stakeholders including pharmacists and health sector administrators involved in the delivery of CAR-T in the clinic.

Background/Introduction

Left ventricular global longitudinal strain (LVGLS) can detect early myocardial changes prior to clinical abnormalities arising, and is a strong prognostic indicator of future cardiovascular (CV) dysfunction and mortality. It is well established that exercise improves CV function and reduces risk of CV disease. However, the impact of exercise on LVGLS is currently unclear. If LVGLS increases in response to habitual exercise, it could offer a sensitive measure that can determine the effectiveness of an exercise regime on CV health.

Purpose

The aim of this systematic review and meta-analysis was to determine whether exercise impacts LVGLS across a range of healthy and diseased populations.

Methods

Four databases (Medline, Scopus, eMbase, SPORTDiscus) were searched in November 2020. Included studies assessed LVGLS before and after an exercise intervention (minimum 2 weeks) in adults aged 18 years and over, and were published in English from 2000 onwards. Random-effects meta-analyses were performed at a study level using Stata (v16.1) to calculate summary standardized mean differences (SMD) and 95% confidence intervals (CI). 39 studies met selection criteria, with 35 included in meta-analyses (1765 participants).

Primary meta-analyses included only studies that compared outcomes between one or more intervention arms to a standard (non-exercising) control arm (RCT’s, N-RCT’s, randomised crossover). Secondary analyses included data from studies with intervention arms only (single group pre-post studies, intervention group from RCT’s, N-RCT’s, randomised crossover).

Results

Primary:

In populations with CV disease, a moderate effect of exercise was observed compared to non-exercising controls (SMD = 0.59; 95% CI, 0.16-1.02; p = 0.01 – figure 1a). No significant effect of exercise was observed for CV risk (SMD = 0.07; 95% CI, -0.15-0.29; p = 0.56 – figure 1b) and healthy (SMD = -0.20; 95% CI, -0.73-0.33; p = 0.45) populations compared to non-exercising controls.

Secondary

In secondary meta-analyses, significant effects of exercise were observed in CV disease (SMD = 0.26; 95% CI, 0.07-0.46; p = 0.01), CV risk (SMD = 0.54; 95% CI, 0.15-0.93; p = 0.01), chronic kidney disease (SMD = 0.65; 95% CI, 0.03-1.28; p = 0.04) and athletic (SMD = 0.30; 95% CI, 0.20-0.41; p= <0.001) populations.

Conclusion(s)

Increases in LVGLS observed in populations with CV disease may assist the prevention of secondary CV events. Secondary findings may support the use of exercise across a range of populations to increase LVGLS and enhance CV function. Future research must address the methodological limitations that currently exist, including improving upon study designs and reporting of individual data. Abstract Figure.

Behcet's Disease (BD) Presenting as a Cerebral Venous Sinus Thrombosis (CVST)

Presentation 20 year old Caucasian male presented to eye casualty 4 weeks post initial diagnosis of bilateral acute anterior uveitis (AAU), with a three-week history of a progressively worsening headache associated with nausea and vomiting. Diagnosis Non-contrast Computed Topography of the head and Magnetic Resonance venogram revealed a cerebral venous sinus thrombosis (CVST). He had a long-standing history of intermittent oral ulceration, and was diagnosed with Neuro Behcet's Disease (NBD). Treatment The patient was commenced on a therapeutic dose of enoxaparin and prednisolone, and was discharged on enoxaparin, warfarin, tapering prednisolone and azathioprine. Discussion/Conclusion NBD is a rare, but serious manifestation of BD. BD is an important differential diagnosis in a young patient presenting with CVST or bilateral AAU.

Transdermal Buprenorphine for Pain Management Following a Neck of Femur Fracture

Introduction

Pain management in patients with hip fractures can be challenging. Poor pain control is associated with reduced mobility and increased morbidity. Inadequate analgesia in patients with dementia is a concern. After using several different alternatives, transdermal buprenorphine was chosen as a standardised approach for analgesia in patients with fragility fracture in our hospital. There is limited evidence on the use of buprenorphine in this population. Our aim was to investigate the safety and effectiveness of transdermal buprenorphine in patients with hip fractures.

Methods

A review of consecutive patients presenting with a hip fracture from June 2018 to December 2018 was conducted using medical records. Our primary outcome was the incidence of complications as a consequence of transdermal buprenorphine. Our secondary outcome was adequate analgesia measured by reviewing the requirement for analgesia during the first week following the patient’s admission. Analgesia demands were considered adequate if patients required less than 20 mg of oral morphine in total during the first week following injury.

Results

In total, 148 patients presented with a hip fracture during the study period. 128 patients had documented evidence of buprenorphine patch application. Complete data was available for the primary outcome of complications in all cases. Data was available for the secondary outcome in 124 patients. Buprenorphine was discontinued in 24 patients (19%), most commonly due to due to concerns about contribution to hypoactive delirium (9%), and when strong analgesia was no longer required (4%). There were no severe complications. Adequate analgesia was achieved using this regime in 68% patients. 38 patients (32%) required more than 20 mg of oral morphine sulphate solution in the first week post-admission.

Conclusion

This series suggests that transdermal buprenorphine is safe and effective in the management of pain following a neck of femur fragility fracture.

904 ‘Excuse me, Sir?’ - A Case for Compassion and Non-discrimination in Surgery

Background

The delivery of compassionate and non-discriminatory care to all patients in the hospital environment is vital. Yet, this striking surgical case report demonstrates that ignorance and prejudice against transgender patients still exists, resulting in poorer health outcomes.

Case presentation

A 64-year-old transgender woman presented with severe epigastric pain and left arm weakness. She became haemodynamically unstable as a result of Type A aortic dissection during thrombolysis for a presumed ischaemic stroke. The patient was addressed as ‘Sir’ on multiple occasions causing her visible distress; she confided in the team that she felt judged and that her concerns were not taken seriously. When the thoracic surgery registrar was informed that the patient was transgender and used female pronouns, their reply was that this information was ‘irrelevant’ and ‘unimportant’.

Conclusions

Barriers to health care for transgender individuals and a focus on compassion when treating the surgical patient are discussed. A lack of education, individual ignorance and the serious nature of this case led to psychological distress and may have contributed to a delay in diagnosis. There is an urgent need to raise awareness of transgender health disparities in medical and surgical training, to ensure that all patients are treated equally, and their dignity is maintained, even in challenging and stressful situations. Appropriate engagement and leadership from senior members of the surgical team will foster non-discriminatory practices and the creation of an inclusive environment, focusing on the use of correct pronouns and addressing patient concerns.

Owner-Reported Pica in Domestic Cats Enrolled onto a Birth Cohort Study

Simple Summary

This study investigated the types of materials targeted by cats eating non-nutritive materials (‘pica’), at about 6, 12 and 18 months of age, as reported by owners. Pica was most common at about 6 months, as compared to the older age categories. Most cats targeted a single type of material, with plastics and other materials being chewed or eaten more commonly than wool or other fabrics. The factors associated with the occurrence of “chronic pica” (pica exhibited at all three timepoints) in cats were also investigated. Moving to a new house, renting rather than owning a home, and living in a household without a dog(s) were factors found to increase the odds of a cat displaying chronic pica.

Abstract

The prevalence and cooccurrence of pica towards different target materials were investigated using prospective data from three questionnaires completed by owners participating in a longitudinal study of UK pet cats. Pica towards one or more material types was reported in 42.9% (229/534), 32.0% (171/534), and 30.9% (165/534) of cats aged approximately 6, 12, and 18 months, respectively. At all timepoints, it was most common for only one material type to be targeted. Associations between potential explanatory variables and “chronic pica” (pica exhibited at all three timepoints) were also explored. Multivariable logistic regression revealed moving to a new house when the cat was aged approximately 6–12 months, renting rather than owning a home, and living in a household without a dog(s) when the cat was aged 2–4 months increased the odds of chronic pica occurrence. This study provides novel data from a cohort of UK pet cats and it is hoped this will increase the understanding of pica and provide direction for areas for future research.

The effect of iron deficiency and anaemia on women's health

Iron deficiency and anaemia are global health problems and major causes of morbidity in women. Current definitions of anaemia in women are historic and have been challenged by recent data from observational studies. Menstrual loss, abnormal uterine bleeding and pregnancy put women at risk of developing iron deficiency which can result in severe fatigue, reduced exercise capacity and poor work performance. Iron deficiency and anaemia during pregnancy are associated with adverse maternal and fetal outcomes, including neurocognitive deficits in children born to iron-deficient mothers. Both iron deficiency and anaemia are common in women undergoing surgery but their association with poor outcomes remains uncertain. The enduring burden of iron deficiency and anaemia in women suggests that current strategies for recognition, prevention and treatment are limited in their utility. Improvements in our understanding of iron homeostasis and the development of new iron preparations, which are better absorbed with fewer side-effects, may improve therapeutic effectiveness of oral iron. Intravenous iron is efficacious for correcting anaemia rapidly but high-quality data on patient-centred outcomes and cost-effectiveness are currently lacking. Many recommendations for the treatment of iron deficiency and anaemia in national guidelines are not supported by high-quality evidence. There is a need for robust epidemiological data and well-designed clinical trials. The latter will require collaborative working between researchers and patients to design studies in ways that incorporate patients' perspectives on the research process and target outcomes that matter to them.

First-dose ChAdOx1 and BNT162b2 COVID-19 vaccines and thrombocytopenic, thromboembolic and hemorrhagic events in Scotland

Reports of ChAdOx1 vaccine-associated thrombocytopenia and vascular adverse events have led to some countries restricting its use. Using a national prospective cohort, we estimated associations between exposure to first-dose ChAdOx1 or BNT162b2 vaccination and hematological and vascular adverse events using a nested incident-matched case-control study and a confirmatory self-controlled case series (SCCS) analysis. An association was found between ChAdOx1 vaccination and idiopathic thrombocytopenic purpura (ITP) (0-27 d after vaccination; adjusted rate ratio (aRR) = 5.77, 95% confidence interval (CI), 2.41-13.83), with an estimated incidence of 1.13 (0.62-1.63) cases per 100,000 doses. An SCCS analysis confirmed that this was unlikely due to bias (RR = 1.98 (1.29-3.02)). There was also an increased risk for arterial thromboembolic events (aRR = 1.22, 1.12-1.34) 0-27 d after vaccination, with an SCCS RR of 0.97 (0.93-1.02). For hemorrhagic events 0-27 d after vaccination, the aRR was 1.48 (1.12-1.96), with an SCCS RR of 0.95 (0.82-1.11). A first dose of ChAdOx1 was found to be associated with small increased risks of ITP, with suggestive evidence of an increased risk of arterial thromboembolic and hemorrhagic events. The attenuation of effect found in the SCCS analysis means that there is the potential for overestimation of the reported results, which might indicate the presence of some residual confounding or confounding by indication. Public health authorities should inform their jurisdictions of these relatively small increased risks associated with ChAdOx1. No positive associations were seen between BNT162b2 and thrombocytopenic, thromboembolic and hemorrhagic events.

Investigation and management of prosthetic joint infection in knee replacement: A BASK Surgical Practice Guideline

BACKGROUND

The burden of knee replacement prosthetic joint infection (KR PJI) is increasing. KR PJI is difficult to treat, outcomes can be poor and it is financially expensive and limited evidence is available to guide treatment decisions.

AIM

To provide guidelines for surgeons and units treating KR PJI.

METHODS

Guideline formation by consensus process undertaken by BASK's Revision Knee Working Group, supported by outputs from UK-PJI meetings.

RESULTS

Improved outcomes should be achieved through provision of care by revision centres in a network model. Treatment of KR PJI should only be undertaken at specialist units with the required infrastructure and a regular infection MDT. This document outlines practice guidelines for units providing a KR PJI service and sets out: CONCLUSIONS: KR PJI patients treated within the NHS should be provided the best care possible. This report sets out guidance and support for surgeons and units to achieve this.

Enhanced surveillance of COVID-19 in Scotland: population-based seroprevalence surveillance for SARS-CoV-2 during the first wave of the epidemic

Objectives

The impact of the COVID-19 pandemic in Scotland has been amongst the most severe in Europe. Serological surveillance is critical to determine the overall extent of infection across populations and to inform the public health response. This study aimed to estimate the proportion of people who have antibodies to SARS-CoV-2 (‘seroprevalence’) in the general population of Scotland and to see if this changes over time.

Study design/Methods

Between International Organization for Standardization (ISO) week 17 (i.e. week commencing 20th April) and ISO week 25 (week commencing 15 June), 4751 residual blood samples were obtained from regional biochemistry laboratories in six participating regional health authority areas covering approximately 75% of the Scottish population. Samples were tested for the presence of anti-SARS-CoV-2 IgG antibodies using the LIAISON®SARS-CoV-2 S1/S2 IgG assay (DiaSorin, Italy). Seroprevalence rates were adjusted for the sensitivity and specificity of the assay using Bayesian methods.

Results

The combined adjusted seroprevalence across the study period was 4.3% (95% confidence interval: 4.2%–4.5%). The proportion varied each week between 1.9% and 6.8% with no difference in antibody positivity by age, sex or geographical area.

Conclusions

At the end of the first wave of the COVID-19 pandemic, only a small fraction of the Scottish population had antibodies to SARS-CoV-2. Control of COVID-19 requires the ability to detect asymptomatic and mild infections that would otherwise remain undetected through existing surveillance systems. This is important to determine the true number of infections within the general population which, in turn, can help to understand transmission, inform control measures and provide a denominator for the estimation of severity measures such as the proportion of infected people who have been hospitalised and/or have died.

Retrospective audit of inter-fraction motion for pelvic node radiotherapy in prostate cancer patients

INTRODUCTION

Pelvic lymph nodes move independently to the prostate. When delivering radiotherapy to prostate and pelvic lymph nodes, daily inter- and intra-fraction anatomical changes need to be accounted for. Planning target volume (PTV) margins, grown from the pelvic lymph node clinical target volume need to be determined, to account for this variation in position.

METHODS

Twenty patients who had daily online image guided radiotherapy to prostate and pelvic lymph nodes between April and December 2018 were selected. Ten pre-treatment verification images using cone beam CT from each patient were registered to pelvic bone anatomy, prostate soft tissue or fiducial markers and pelvic lymph node soft tissue to assess the accuracy of treatment delivery. Population systematic and random errors and PTV margins were calculated.

RESULTS

PTV margins of 0.4 cm, 0.4 cm and 0.7 cm left-right (LR), superior-inferior (SI) and anterior-posterior (AP) respectively were derived for the pelvic lymph nodes when registering to prostate. PTV margins of 0.3 cm, 0.2 cm and 0.4 cm LR, SI and AP respectively were derived for the pelvic lymph nodes when registering to bone. There was a posterior systematic shift of the prostate during the treatment course.

CONCLUSION

There is differential motion of pelvic lymph nodes to prostate and in the era of prostate and pelvic radiotherapy for patients with node positive prostate cancer; there is increasing importance in the accuracy of dose delivery to the involved lymph node. Hence, this group of patients may benefit from personalised radiotherapy PTV margins, especially if the involved pelvic lymph node is within the anterior part of the clinical target volume.

IMPLICATIONS FOR PRACTICE

Optimisation of dose delivery to the pelvic lymph nodes when prioritising the prostate in prostate and pelvic lymph node image guided radiotherapy.

Differential influences of early growth and social factors on young children's cognitive performance in four low-and-middle-income birth cohorts (Brazil, Guatemala, Philippines, and South Africa)

Background

Studies relating childhood cognitive development to poor linear growth seldom take adequate account of social conditions related to both, leading to a focus on nutrition interventions. We aimed to assess the roles of both biological and social conditions in determining early childhood cognition, mediated by birthweight and early linear growth.

Methods

After exploratory structural equation modelling to identify determining factors, we tested direct and indirect paths to cognitive performance through birthweight and child height-for-age at 2 years, assessed between 4 and 8.5 years of age among 2448 children in four birth cohort studies in low-and-middle-income countries (Brazil, Guatemala, Philippines and South Africa). Determinants were compared across the cohorts.

Findings

Three factors yielded excellent fit, comprising birth endowment (primarily maternal age and birth order), household resources (crowding, dependency) and parental capacity (parental education). We estimated their strength together with maternal height in determining cognitive performance. Percentage shares of total effects of the four determinants show a marked transition from mainly biological determinants of birth weight (birth endowment 34%) and maternal height (30%) compared to household resources (25%) and parental capacity (11%), through largely economic determinants of height at 2 years (household resources (60%) to cognitive performance being predominantly determined by parental capacity (64%) followed by household resources (29%). The largely biological factor, birth endowment (maternal age and birth order) contributed only 7% to childhood cognitive performance and maternal height was insignificant. In summary, the combined share of social total effects (household resources and parental capacity) rises from 36∙2% on birth weight, to 78∙2% on height for age at 24 m, and 93∙4% on cognitive functioning.

Interpretation

Across four low- and middle-income contexts, cognition in childhood is influenced more by the parental capacity of families and their economic resources than by birth weight and early linear growth. Improving children's cognitive functioning requires multi-sectoral interventions to improve parental education and enhance their economic wellbeing, interventions that are known to improve also early childhood growth.

•

We aimed to investigate separate and combined biological and social determination of young children’s cognitive performance.

•

We used path analysis of longitudinal data from birth cohort studies in four differing low-and-middle countries.

•

We distinguished biological and social factors, as well as household resources from parental capacity.

•

Biological factors determine birthweight, 2-year height depends on social factors, and the latter drive child cognitive performance.

•

No single domain intervention provides both necessary and sufficient support for young children’s unfolding development.

Sleep Duration and Behaviours: A Descriptive Analysis of a Cohort of Dogs up to 12 Months of Age

Sleep is a vital behaviour that can reflect an animal's adaptation to the environment and their welfare. However, a better understanding of normal age-specific sleep patterns is crucial. This study aims to provide population norms and descriptions of sleep-related behaviours for 16-week-old puppies and 12-month-old dogs living in domestic environments. Participants recruited to a longitudinal study answered questions relating to their dogs' sleep behaviours in surveys issued to them when their dogs reached 16 weeks (n = 2332) and 12 months of age (n = 1091). For the statistical analysis, subpopulations of dogs with data regarding sleep duration at both timepoints were used. Owners of 16-week-old puppies perceived their dogs to sleep longer during the day and over a 24 h period, but for less time during the night than owners of 12-month-old dogs. At both timepoints, dogs were most commonly settled to sleep by being left in a room/area without human company. However, of dogs that had access to people overnight, 86.7% and 86.8% chose to be around people at 16 weeks and 12 months of age, respectively. The most common sleeping place was in a kennel/crate at 16 weeks (49.1%), and a dog bed at 12 months (31.7%). Future research within this longitudinal study will investigate how sleep duration and behaviours change with age and impact on a dog's health and behaviour.

Silicosis and pulmonary tuberculosis in deceased female South African miners

BACKGROUND

Implementation of South Africa's 2002 Mining Charter increased women's participation in underground mining. However, occupational lung diseases (OLDs) in female gold miners have not been studied.

AIMS

To compare autopsy-diagnosed pulmonary silicosis, lymph gland silicosis (a precursor of pulmonary silicosis) and active pulmonary tuberculosis (PTB) in South African gold miners.

METHODS

The law allows for autopsies on miners for OLD compensation. Information is stored on the Pathology Automation (PATHAUT) database. We selected records of deceased miners who had worked only in gold mines, started employment from 2002, and were autopsied between 2005 and 2015. Using descriptive statistics, we compared demographic and employment characteristics, and disease proportions by sex.

RESULTS

The study comprised 847 gold miners: 68 women and 779 men. There were no statistically significant differences in proportions of autopsy-diagnosed pulmonary silicosis [3 (4%) in women and 54 (7%) in men], lymph gland silicosis [11 (16%) and 171 (22%)] or PTB [29 (43%) and 254 (33%)]. Age and employment duration in women and men with disease were similar. Most miners with pulmonary silicosis had started employment from 2003 [315 (77%)] and worked for under 10 years.

CONCLUSION

It is important to report research findings by sex. Proportions of silicosis and PTB were comparable in women and men, suggesting similar exposures. Silicosis detection after short employment indicates inadequate dust control, particularly as most entered the industry after implementation of interventions to control silica dust in 2003.
