Impact of the COVID-19 pandemic on paediatric patients with cancer in low-income, middle-income and high-income countries: protocol for a multicentre, international, observational cohort study
Authors: Peter Noel , Bandyopadhyay Soham , Lakhoo Kokila 
Published: June 2021

IntroductionChildhood cancers are a leading cause of non-communicable disease deaths for children around the world. The COVID-19 pandemic may have impacted on global children’s cancer services, which can have consequences for childhood cancer outcomes. The Global Health Research Group on Children’s Non-Communicable Diseases is currently undertaking the first international cohort study to determine the variation in paediatric cancer management during the COVID-19 pandemic, and the short-term to medium-term impacts on childhood cancer outcomes.Methods and analysisThis is a multicentre, international cohort study that will use routinely collected hospital data in a deidentified and anonymised form. Patients will be recruited consecutively into the study, with a 12-month follow-up period. Patients will be included if they are below the age of 18 years and undergoing anticancer treatment for the following cancers: acute lymphoblastic leukaemia, Burkitt lymphoma, Hodgkin lymphoma, Wilms tumour, sarcoma, retinoblastoma, gliomas, medulloblastomas and neuroblastomas. Patients must be newly presented or must be undergoing active anticancer treatment from 12 March 2020 to 12 December 2020. The primary objective of the study was to determine all-cause mortality rates of 30 days, 90 days and 12 months. This study will examine the factors that influenced these outcomes. χ2analysis will be used to compare mortality between low-income and middle-income countries and high-income countries. Multilevel, multivariable logistic regression analysis will be undertaken to identify patient-level and hospital-level factors affecting outcomes with adjustment for confounding factors.Ethics and disseminationAt the host centre, this study was deemed to be exempt from ethical committee approval due to the use of anonymised registry data. At other centres, participating collaborators have gained local approvals in accordance with their institutional ethical regulations. Collaborators will be encouraged to present the results locally, nationally and internationally. The results will be submitted for publication in a peer-reviewed journal.

IntroductionOlder adults with cancer suffer from the combined effects of ageing, cancer disease and treatment side effects. The main treatment for patients with haematological malignancies is chemotherapy, associated with significant toxicities. Chemotherapy can alter patients’ physical function and quality of life which are often already diminished in older patients due to ageing and comorbidities. It therefore seems essential to develop and to evaluate interventions capable of preventing physical and psychosocial decline and its consequences. Promoting physical activity is a promising approach to improve physical function and quality of life in older adults with cancer, but there are limited data on the feasibility of such interventions among older patients with haematological malignancies, concomitant to chemotherapy.Methods and analysisOCAPI (OnCogeriatric and Individualized Physical Activity) is a single-arm, interdisciplinary, prospective, interventional, feasibility study. It is intended to include 40 patients (20 patients with acute myeloid leukaemia and 20 patients with non-Hodgkin’s lymphoma) over 65 years in an individualised 6-month physical activity programme. The programme consists of individually supervised exercise sessions with an increasing volume of physical activity either at home and/or in a laminar airflow room (depending on the disease and treatment regimen) followed by unsupervised sessions and phone follow-ups. Patients will receive an activity tracker during the 6 months of the programme. Evaluations will take place at inclusion and at 3, 6 and 12 months to assess the feasibility of the programme and to explore potential changes in physical, psychosocial and clinical outcomes. The results will generate preliminary data to implement a larger randomised controlled trial.Ethics and disseminationThe study protocol was approved by the French ethics committee (Comité de protection des personnes Est I, N°ID-RCB 2019-A01231-56, 12 July 2019). All participants will have to sign and date an informed consent form. The findings will be disseminated in peer-reviewed journals and academic conferences.Trial registration numberNCT04052126.

Published: June 2021

Study objectivesTo investigate the association between admission blood glucose levels and 28-day mortality as well as in-hospital complications in older patients with incident acute myocardial infarction (AMI) undergoing modern treatment.MethodsFrom a German population-based regional MI registry, 5530 patients (2016 women), aged 65–84 years, hospitalised with an incident AMI between 1 January 2009 and 31 December 2016 were included in the study. Multivariable logistic regression models were used to assess the associations between admission blood glucose and 28-day mortality as well as in-hospital complications after AMI. Analyses stratified according to age, diabetes and type of infarction (ST-elevation MI (STEMI)/non-STEMI) were conducted.ResultsThe adjusted ORs for the association between admission blood glucose and 28-day mortality in young-old (65–74 years) and old (75–84 years) patients with AMI were 1.40 (95% CI: 1.21 to 1.62) and 1.21 (95% CI: 0.98 to 1.50) per 1 SD increase in admission blood glucose, respectively. Furthermore, higher admission blood glucose was related to case fatality irrespective of the diabetes status and type of infarction only in the under-75 group. For the patients aged 75–84 years, it was only true for those without diabetes and STEMI. Admission blood glucose was also associated with major cardiac complications in both age groups.ConclusionAdmission blood glucose was significantly associated with 28-day case fatality in patients with AMI aged 65–74 years but not 75–84 years; furthermore, in both age groups there was an increased risk of major complications. It seems that admission glucose may play a rather minor role in terms of case fatality in higher aged patients with AMI.

Published: June 2021

IntroductionThe introduction of trauma systems that began in the 1970s resulted in improved trauma care and a decreased rate of morbidity and mortality of trauma patients. Worldwide, little is known about the effectiveness of trauma care system at different stages of development, from establishing a trauma centre, to implementing a trauma system and as trauma systems mature. The objective of this study is to extract and analyse data from research that evaluates mortality rates according to different stages of trauma system development globally.Methods and analysisThe proposed review will comply with the checklist of the ‘Preferred reporting items for systematic review and meta-analysis’. In this review, only peer-reviewed articles written in English, human-related studies and published between January 2000 and December 2020 will be included. Articles will be retrieved from MEDLINE, EMBASE and CINAHL. Additional articles will be identified from other sources such as references of included articles and author lists. Two independent authors will assess the eligibility of studies as well as critically appraise and assess the methodological quality of all included studies using the Cochrane Risk of Bias for Non-randomised Studies of Interventions tool. Two independent authors will extract the data to minimise errors and bias during the process of data extraction using an extraction tool developed by the authors. For analysis calculation, effect sizes will be expressed as risk ratios or ORs for dichotomous data or weighted (or standardised) mean differences and 95% CIs for continuous data in this systematic review.Ethics and disseminationThis systematic review will use secondary data only, therefore, research ethics approval is not required. The results from this study will be submitted to a peer-review journal for publication and we will present our findings at national and international conferences.PROSPERO registration numberCRD42019142842.

IntroductionThe ERAS protocol (Enhanced Recovery After Surgery) is a multimodal pathway aimed to reduce surgical stress and to allow a rapid postoperative recovery. Application of the ERAS protocol to colorectal cancer surgery has been limited to a minority of hospitals in Italy. To promote the systematic adoption of ERAS in the entire regional hospital network in Piemonte an Audit and Feedback approach (A&F) has been adopted together with a cluster randomised trial to estimate the true impact of the protocol on a large, unselected population.MethodsA multicentre stepped wedge cluster randomised trial is designed for comparison between standard perioperative management and the management according to the ERAS protocol. The primary outcome is the length of hospital stay (LOS). Secondary outcomes are: incidence of postoperative complications, time to patients’ recovery, control of pain and patients’ satisfaction. With an A&F approach the adherence to the ERAS items is monitored through a dedicated area in the study web site. The study includes 28 surgical centres, stratified by activity volume and randomly divided into four groups. Each group is randomly assigned to a different activation period of the ERAS protocol. There are four activation periods, one every 3 months. However, the planned calendar and the total duration of the study have been extended by 6 months due to the COVID-19 pandemic.The expected sample size of about 2200 patients has a high statistical power (98%) to detect a reduction of LOS of 1 day and to estimate clinically meaningful changes in the other endpoints.Ethics and disseminationThe study protocol has been approved by the Ethical Committee of the coordinating centre and by all participating centres. Study results will be timely circulated within the hospital network and published in peer-reviewed journals.Trial registration numberNCT04037787.
Does living at moderate altitudes in Austria affect mortality rates of various causes? An ecological study
Authors: Burtscher Johannes , Millet Gregoire P , Burtscher Martin 
Published: June 2021

ObjectivesThe effects of altitude residence on ageing, longevity and mortality are poorly understood. While adaptations to chronic exposure to altitude may exert beneficial effects on cardiovascular risk factors and some types of cancer, an elevated risk to die from chronic respiratory diseases has been reported. Moreover, high-altitude residence may be correlated with increased depression and suicide rates. The present study tested the hypothesis that living at moderate altitudes (up to 2000 m) is associated with reduced mortality from all causes.Setting and participantsWe used a dataset comprising all deaths (n=467 834) across 10 years of a country (Austria) characterised by varying levels of altitudes up to 2000 m.Main outcome measuresTotal number of deaths, age-standardised mortality rates (ASMRs) per 100 000 population, cause-specific ASMRs.ResultsASMRs for residents living in higher (>1000 m) versus lower (<251 m) altitude regions (with agriculture employment below 3%) were 485.8 versus 597.0 (rate ratio and 95% CI 0.81 (0.72 to 0.92); p<0.001) for men and 284.6 versus 365.5 (0.78; 0.66 to 0.91); p=0.002) for women. Higher levels of agriculture employment did not influence mortality rates. Diseases of the circulatory system and cancers were main contributors to lower mortality rates at higher altitude. Residence at higher altitude did not negatively affect mortality rates from any other diseases. We highlight gender effects and—beside environmental factors—also discuss socioeconomic factors that may be responsible for conflicting results with data from other populations.ConclusionsLiving at moderate altitude (1000–2000 m) elicits beneficial effects on all-cause mortality for both sexes, primarily due to lower ASMRs from circulatory diseases and cancer. The presented analysis on cause-specific ASMRs over a 10-year period among the entire population of an alpine country will contribute to a better understanding on the effects of altitude-related mortality.

Published: June 2021

BackgroundGood end-of-life care is essential to ensure dignity and comfort in death. To our knowledge, there has not been a national population-based study in England of community prescribing of all drugs used in end-of-life care for patients with cancer.Methods57 632 people who died from malignant cancer in their own home or in a care home in 2017 in England were included in this study. National routinely collected data were used to examine community prescriptions dispensed for drugs for symptom control and anticipatory prescribing by key sociodemographic factors in the last 4 months of life.Results94% of people who died received drugs to control their symptoms and 65% received anticipatory prescribing. Prescribing increased for the symptom control drug group (53% to 75%) and the anticipatory prescribing group (4% to 52%) over the 4-month period to death.ConclusionsMost individuals who died of cancer in their own home or a care home were dispensed drugs commonly used to control symptoms at the end of life, as recommended by best-practice guidance. Lower prescribing activity was found for those who died in a care home, highlighting a potential need for improved end-of-life service planning.

Published: June 2021

BackgroundInsufficient knowledge about end-of-life law can impede the provision of safe and high-quality end-of-life care. Accurate legal knowledge across health professions is critical in palliative and end-of-life settings given the reliance on multidisciplinary care. Most research has focused on doctors, finding significant knowledge gaps. The limited evidence about other health professions also suggests legal knowledge deficits.ObjectiveTo determine and compare levels of knowledge about end-of-life law across a broad sample of Australian health professionals and medical students, and to identify predictors of legal knowledge.MethodsAn online pre-training survey was completed by participants enrolled in a national training programme on end-of-life law. The optional survey collected demographic data and measured baseline legal knowledge and attitudes towards end-of-life law.ResultsResponse rate was 67% (1653/2456). The final sample for analysis (n=1564, 95% of respondents), included doctors, medical students, nurses and a range of allied health professionals. Doctors and nurses had slightly higher levels of legal knowledge than did medical students and allied health professionals; all had critical knowledge gaps. Demographic and professional characteristics predicted knowledge levels, with experience of end-of-life law in practice, confidence applying law and recent continuing professional development being positively associated with legal knowledge.ConclusionsThis study provides new evidence about legal knowledge across a broad range of health professions. While knowledge levels varied somewhat across professions, knowledge gaps were observed in all professional groups. Education and training initiatives to enhance knowledge of end-of-life law should be tailored to meet the specific needs of each profession.

BackgroundAround 40% of patients with bipolar disorder (BD) additionally have anxiety disorder. The prevalence of anxiety in patients with newly diagnosed BD and their first-degree relatives (UR) has not been investigated.ObjectiveTo investigate (1) the prevalence of a comorbid anxiety diagnosis in patients with newly diagnosed BD and their UR, (2) sociodemographic and clinical differences between patients with and without a comorbid anxiety diagnosis and (3) the association between smartphone-based patient-reported anxiety and observer-based ratings of anxiety and functioning, respectively.MethodsWe recruited 372 patients with BD and 116 of their UR. Daily smartphone-based data were provided from 125 patients. SCAN was used to assess comorbid anxiety diagnoses.FindingsIn patients with BD, the prevalence of a comorbid anxiety disorder was 11.3% (N=42) and 10.3% and 5.9% in partial and full remission, respectively. In UR, the prevalence was 6.9%. Patients with a comorbid anxiety disorder had longer illness duration (p=0.016) and higher number of affective episodes (p=0.011). Smartphone-based patient-reported anxiety symptoms were associated with ratings of anxiety and impaired functioning (p<0.001).LimitationsThe SCAN interviews to diagnose comorbid anxiety disorder were carried out regardless of the participants’ mood state.Clinical implicationsThe lower prevalence of anxiety in newly diagnosed BD than in later stages of BD indicates that anxiety increases with progression of BD. Comorbid anxiety seems associated with poorer clinical outcomes and functioning and smartphones are clinically useful for monitoring anxiety symptoms.Trial registration numberClinicalTrials.gov Registry (NCT02888262).
Retention of doctors in emergency medicine: a scoping review of the academic literature
Authors: Darbyshire Daniel , Brewster Liz , Isba Rachel , Body Richard , Basit Usama , Goodwin Dawn 
Published: June 2021

IntroductionWorkforce issues prevail across healthcare; in emergency medicine (EM), previous work improved retention, but the staffing problem changed rather than improved. More experienced doctors provide higher quality and more cost-effective care, and turnover of these physicians is expensive. Research focusing on staff retention is an urgent priority.MethodsThis study is a scoping review of the academic literature relating to the retention of doctors in EM and describes current evidence about sustainable careers (focusing on factors influencing retention), as well as interventions to improve retention. The established and rigorous JBI scoping review methodology was followed. The data sources searched were MEDLINE, Embase, Cochrane, HMIC and PsycINFO, with papers published up to April 2020 included. Broad eligibility criteria were used to identify papers about retention or related terms, including turnover, sustainability, exodus, intention to quit and attrition, whose population included emergency physicians within the setting of the ED. Papers which solely measured the rate of one of these concepts were excluded.ResultsEighteen papers met the inclusion criteria. Multiple factors were identified as linked with retention, including perceptions about teamwork, excessive workloads, working conditions, errors, teaching and education, portfolio careers, physical and emotional strain, stress, burnout, debt, income, work–life balance and antisocial working patterns. Definitions of key terms were used inconsistently. No factors clearly dominated; studies of correlation between factors were common. There were minimal research reporting interventions.ConclusionMany factors have been linked to retention of doctors in EM, but the research lacks an appreciation of the complexity inherent in career decision-making. A broad approach, addressing multiple factors rather than focusing on single factors, may prove more informative.
Laminoplasty versus laminectomy with fusion for treatment of multilevel cervical compressive myelopathy: an updated meta-analysis

Published: June 2021

AbstractBackgroundMultilevel cervical spondylotic myelopathy (CSM) and ossification of the posterior longitudinal ligament (OPLL) are debilitating degenerative diseases. If conservative treatment is ineffective, surgical options for multilevel CSM and OPLL include laminoplasty (LP) and laminectomy with fusion (LF). In this updated meta-analysis, we aimed to compare the clinical outcomes and complications of both approaches.MethodsWe searched PubMed, the Cochrane Library and Embase datasets from their inception to 31 March 2020, to identify all eligible studies comparing LP versus LF for multilevel CSM and OPLL. Data were extracted according to predefined endpoints. We summarised data by the random-effects or fixed-effect models, as necessary.ResultsOf 533 eligible studies, 16 were identified, which included 638 patients who underwent LP and 671 patients who underwent LF. No significant differences were observed between preoperative and postoperative scores of the Japanese Orthopaedic Association (p=1.0 and 0.20, respectively); Visual Analogue Scale (p=0.24 and 0.89, respectively); sagittal vertical axis ((p=0.16 and 0.87, respectively); Nurick Scale (p=0.59 and 0.17, respectively); and range of motion (p=0.67 and 0.63, respectively). However, total complications were higher for LF compared with LP (p=0.006). A significantly higher incidence of C5 palsy was observed in the LF group (p=0.004). The postoperative Neck Disability Index (NDI) was also higher in the LF group (p&lt;0.001).ConclusionsAlthough LP and LF shared similar clinical improvement, LP had fewer complications, a lower incidence of C5 palsy, and better NDI scores and recovery outcomes than LF. Randomised studies are warranted to validate these findings.
