Abstract
The COVID-19 pandemic has resulted in over 340 million infection cases (as of 21 January 2022) and more than 5.57 million deaths globally. In reaction, science, technology and innovation communities across the globe have organised themselves to contribute to national responses to COVID-19 disease. A significant contribution has been from the establishment of wastewater-based epidemiological (WBE) surveillance interventions and programmes for monitoring the spread of COVID-19 in at least 55 countries. Here, we examine and share experiences and lessons learnt in establishing such surveillance programmes. We use case studies to highlight testing methods and logistics considerations associated in scaling the implementing of such programmes in South Africa, the Netherlands, Turkey and England. The four countries were selected to represent different regions of the world and the perspective based on the considerable progress made in establishing and implementing their national WBE programmes. The selected countries also represent different climatic zones, economies, and development stages, which influence the implementation of national programmes of this nature and magnitude. In addition, the four countries' programmes offer good experiences and lessons learnt since they are systematic, and cover extensive areas, disseminate knowledge locally and internationally and partnered with authorities (government). The programmes also strengthened working relations and partnerships between and among local and global organisations. This paper shares these experiences and lessons to encourage others in the water and public health sectors on the benefits and value of WBE in tackling SARS-CoV-2 and related future circumstances.

Abstract
Enteric fever (EF) is an infection caused by the bacteria called Salmonella Typhi or Paratyphi. Infection is acquired through swallowing contaminated food or water. Most EF in England occurs in people returning from South Asia and other places where EF is common; catching EF in England is rare. The main symptom is fever, but stomach pain, diarrhoea, muscle aches, rash and other symptoms may occur. EF is diagnosed by culturing the bacteria from blood and/or stool in a microbiology laboratory. EF usually responds well to antibiotic treatment. Depending on how unwell the individual is, antibiotics may be administered by mouth or by injection. Over the past several years, there has been an overall increase in resistance to antibiotics used to treat enteric fever, in all endemic areas. Additionally, since 2016, there has been an ongoing outbreak of drug-resistant EF in Pakistan. This infection is called extensively drug-resistant, or XDR, EF and only responds to a limited number of antibiotics. Occasionally individuals develop complications of EF including confusion, bleeding, a hole in the gut or an infection of the bones or elsewhere. Some people may continue to carry the bacteria in their stool for a longtime following treatment for the initial illness. These people may need treatment with a longer course of antibiotics to eradicate infection. Travellers can reduce their risk of acquiring EF by following safe food and water practices and by receiving the vaccine at least a few weeks before travel. These guidelines aim to help doctors do the correct tests and treat patients for enteric fever in England but may also be useful to doctors and public health professionals in other similar countries.

Abstract
Abstract
Background: Literature has shown that racial, ethnic, and gender disparities exist among clinical research participants and within the ranks of academic institutions. To assess this and develop solutions to potential disparities in pediatric neuro-oncology, the Pacific Pediatric Neuro-Oncology Consortium (PNOC) and Children's Brain Tumor Network (CBTN) Diversity, Equity, and Inclusion (DEI) working group distributed a survey to all members of the consortia regarding the state of DEI in our research environments. In parallel, the working group collated clinical data from a public CBTN dataset and a PNOC clinical trial patient cohort to assess racial, ethnic, and gender differences in clinical research participation and outcomes. Methods: This study consisted of two components: an electronically distributed REDCap survey of all PNOC and CBTN consortia members (distributed Fall 2020) and analysis of pediatric neuro-oncology patient cohorts from CBTN and PNOC. The survey collected demographic information of respondents and Likert opinions on DEI at the consortia- and institution level (e.g. “All team members are treated fairly”). Responses were then stratified based on self-identified race, ethnicity, and gender and by age and job title. Patient-level data from the CBTN and PNOC cohorts was collated to evaluate overall patient demographics and clinical outcomes stratified by race, ethnicity, and gender and including differences in survival and clinical research enrollment. Outcomes: Fifty-seven PNOC/CBTN members initiated survey responses, with 45 completing the entire survey (estimated 20-25% response rate). Responders were predominantly white, non-hispanic females with the most common age range of 35-44 years and with faculty or physician job titles, followed by clinical research staff. Statistically significant differences were identified in questions related to the DEI environment mainly at the institution-level. Regarding feelings of inclusion, acceptance, and fair treatment, distinctions were identified across self-reported race and gender with white race correlating with higher frequency of feeling included and respected and females most commonly reporting neutral or disagreement that all team members are treated fairly and that different cultures and backgrounds are valued and interact well. At the patient level, the CBTN and PNOC data pulls included 1711 and 463 patients, respectively, with analyses currently underway and to be aligned with data from the Central Brain Tumor Registry of the United States (CBTRUS) to assess for race, ethnicity, gender, and locoregional differences in our patient cohort and in the context of national registry data. Conclusions: The experiences and feelings of inclusion and treatment of clinical research members within the clinical research environment of pediatric neuro-oncology differ based on self-identified race and gender. Investigation is in process to extrapolate patient-level differences across race, ethnicity, and gender and in the context of larger registry data for pediatric neuro-oncology.

Abstract
Background Wearable resistance (WR) training is a modality that allows athletes to perform loaded sport-specific movements to develop force and power outputs. The acute responses by which WR works is still relatively unknown, and the effects of WR load and location of the load has not yet been examined. Objectives To investigate the acute neuromuscular and stride characteristic responses to different wearable resistance (WR) loads and placements on the calf muscles during high-speed running. Methods Ten well-trained subjects completed a workout of ten sets of three 10s runs at 18km.h-1 (20s of rest between runs and one min between sets). Five conditions were tested: (1) unloaded control, (2) bilateral 0.75 vs. 1.5% body mass (BM) loading on the distal posterior calf, (3) bilateral proximal vs. distal loading of 1.5% BM positioned posteriorly, (4) bilateral anterior vs. posterior loading of 1.5% BM positioned distally, (5) unilateral loading of 1.5% BM on the distal posterior calf. Data were collected using Electromyography (EMG) and back-mounted GPS-embedded accelerometers. Magnitude of differences of within athlete and between muscle comparisons were calculated using effect sizes (ES) ± 90% confidence limits (CL). Results No substantial differences in accelerometry data were observed between any of the loaded conditions and the control. EMG activity was lower for proximal loading compared to the control for the gluteus maximus (ES±90%CL; -0.72±0.41), vastus lateralis (-0.89±0.47) and vastus medialis (VM) (-0.97±0.46). Anterior loading induced substantially lower EMG activity for the semitendinosus (-0.70±0.48) and VM (-0.64±0.39) muscles compared with the control. EMG activity of the VM (-0.73±0.46) muscle was also substantially lower for posterior loading compared to the control. Unilateral loading induced no substantial differences in EMG activity between the loaded and unloaded legs. Conclusion This preliminary study has provided a rationale for the performance of further investigations into the effects of WR lower limb loading on stride characteristics and EMG activity from a chronic standpoint using a larger population.

Abstract
Background:Exposure to corticosteroids is recognised to increase the risk of osteoporosis.Objectives:Our aim was to evaluate patients’ short-term absolute risk of osteoporosis over the course of their first continuous exposure to corticosteroids.Methods:This was an observational study using UK data from the Clinical Practice Research Datalink. Adult patients were selected if exposed to systemic corticosteroids for any condition and had no prior osteoporosis. Non-exposed adults matched on age, sex, and disease burden were selected from the general population. Patients were followed from their first exposure to corticosteroid to the earlier of 90 days following the end of continuous prescribing or for a maximum of three years. Cohorts were categorised by age (18-42 years, 43-67 and 68-92 years), BMI (underweight, normal overweight, obese and obese+) and gender. Absolute risk rates were calculated for each of these categories.Results:In total, 573,056 exposed patients were matched 1:1 to non-exposed controls. Mean age was 52 years; 57% were female. The mean and median days’ supply were 50.9 and 13 days, respectively. Underweight females aged 68-92 years exposed to corticosteroids had the highest absolute risk of osteoporosis (70.9 per 1000 patient years (PKPY)); in matched non-exposed controls this was 26.6 PKPY. Generally, following their first continuous exposure to corticosteroids, patients taking steroids had greater risk of osteoporosis compared with those in the same age, sex and BMI category never exposed to corticosteroids.Conclusion:Whilst it is understood that exposure to corticosteroids increases the risk of osteoporosis, there are large differences in risk in accordance with age, sex and BMI. Alternatives to corticosteroids are urgently needed.MaleFemaleSteroid-exposedNever exposedSteroid-exposedNever exposedAge groupBMI groupPatientsAbsolute rate (per 1,000 patient years)PatientsAbsolute rate (per 1,000 patient years)p-valuePatientsAbsolute rate (per 1,000 patient years)PatientsAbsolute rate (per 1,000 patient years)p-value18-421: Underweight1,2422.01,1950.00.56613,0794.53,4860.90.13612: Normal18,7982.219,6380.0<0.000142,2340.947,3400.10.00493: Overweight16,5362.615,1140.00.000124,8930.524,0090.10.23824: Obese +10,3110.68,4530.00.287426,6000.620,3200.30.461443-671: Underweight1,25427.46830.00.00402,42030.91,99018.50.11412: Normal27,0378.626,5692.0<0.000145,46715.950,4236.1<0.00013: Overweight42,4284.343,8720.7<0.000142,62010.843,2534.1<0.00014: Obese +31,4782.530,8520.80.000745,3396.039,8762.4<0.000168-921: Underweight93630.343210.30.15051,53270.91,23926.60.00032: Normal15,89111.315,0214.5<0.000118,30842.318,71718.6<0.00013: Overweight21,3717.323,1371.8<0.000119,14926.219,76012.9<0.00014: Obese +11,2165.611,3961.90.002114,45320.013,6148.7<0.0001Disclosure of Interests:Ellen Berni Consultant of: Employed by Pharmatelligence, which carries out consultancy work for AstraZeneca and other pharmaceutical companies., Philip Ambery Shareholder of: AstraZeneca, Employee of: AstraZeneca, Samuel Adamsson Eryd Shareholder of: AstraZeneca, Employee of: AstraZeneca, Sara Jenkins-Jones Consultant of: Employed by Pharmatelligence, which carries out consultancy work for AstraZeneca and other pharmaceutical companies., Mary Brown Shareholder of: AstraZeneca, Employee of: AstraZeneca, Carol Astbury Shareholder of: AstraZeneca, Employee of: AstraZeneca, Phillip Hunt Shareholder of: AstraZeneca, Employee of: AstraZeneca, Craig Currie Consultant of: Director of Pharmatelligence, which carries out consultancy work for AstraZeneca and other pharmaceutical companies

Abstract
Pediatric brain tumors comprise a heterogeneous molecular and histological landscape that challenges most current precision-medicine approaches. While recent large-scale efforts to molecularly characterize distinct histological entities have dramatically advanced the field’s capacity to classify and further define molecular subtypes, developing therapeutic and less toxic molecularly-defined clinical approaches remains a challenge. To define new approaches to meet these challenges and advance scalable, shared biospecimen- and data-resources for pediatric brain tumors, the Children’s Brain Tumor Network and Pacific Pediatric Neuro-Oncology Consortium, in partnership with the Alex’s Lemonade Stand Foundation Childhood Cancer Data Lab, launched OpenPBTA, a global open science Pediatric Brain Tumor Atlas initiative to comprehensively define the molecular landscape of pediatric brain tumors. The initiative contains multi-modal analyses of research- and clinical-trial based DNA and RNA sequences from nearly 1,000 subjects (with 1,256 tumors) along with their longitudinal clinical data. The OpenPBTA’s open science framework for analysis tests the capacity of crowd-sourced collaborative architectures to advance more rapid, iterative and integrated discovery of the underlying mechanisms of disease across pediatric brain and spinal cord tumors. Since the launch of the project, OpenPBTA has collaboratively created reproducible workflows for integrated consensus SNV, CNV, and fusion calling, enabled RNA-Seq-based classification of medulloblastoma subtypes, and more than 25 additional DNA- and RNA-based analyses. The open-science platform and associated datasets and processed results provide a continuously updated, global view of the integrated cross-disease molecular landscape of pediatric brain tumors. Such biospecimen- and clinically-linked scalable data resources provide unprecedented collaborative opportunities for precision-based, personalized therapeutic discovery and drug development with the upcoming further integration of proteomic sample data (N >300) and drug response datasets, additionally diversifying the multimodal discovery potential of crowd-sourced approaches for accelerated impact for children with brain tumors.

Abstract
BACKGROUND Rates of surgery and adjuvant therapy for breast cancer vary widely between breast units. This may contribute to differences in survival. This cluster RCT evaluated the impact of decision support interventions (DESIs) for older women with breast cancer, to ascertain whether DESIs influenced quality of life, survival, decision quality, and treatment choice. METHODS A multicentre cluster RCT compared the use of two DESIs against usual care in treatment decision-making in older women (aged at least ≥70 years) with breast cancer. Each DESI comprised an online algorithm, booklet, and brief decision aid to inform choices between surgery plus adjuvant endocrine therapy versus primary endocrine therapy, and adjuvant chemotherapy versus no chemotherapy. The primary outcome was quality of life. Secondary outcomes included decision quality measures, survival, and treatment choice. RESULTS A total of 46 breast units were randomized (21 intervention, 25 usual care), recruiting 1339 women (670 intervention, 669 usual care). There was no significant difference in global quality of life at 6 months after the baseline assessment on intention-to-treat analysis (difference -0.20, 95 per cent confidence interval (C.I.) -2.69 to 2.29; P = 0.900). In women offered a choice of primary endocrine therapy versus surgery plus endocrine therapy, knowledge about treatments was greater in the intervention arm (94 versus 74 per cent; P = 0.003). Treatment choice was altered, with a primary endocrine therapy rate among women with oestrogen receptor-positive disease of 21.0 per cent in the intervention versus 15.4 per cent in usual-care sites (difference 5.5 (95 per cent C.I. 1.1 to 10.0) per cent; P = 0.029). The chemotherapy rate was 10.3 per cent at intervention versus 14.8 per cent at usual-care sites (difference -4.5 (C.I. -8.0 to 0) per cent; P = 0.013). Survival was similar in both arms. CONCLUSION The use of DESIs in older women increases knowledge of breast cancer treatment options, facilitates shared decision-making, and alters treatment selection.

Abstract
BACKGROUND AND PURPOSE Maintaining carotid patency and avoiding symptomatic intracranial hemorrhage are competing concerns in tandem occlusions. This study provides data regarding the safety and efficacy of eptifibatide in stroke from tandem occlusion of the extracranial carotid artery and the intracranial carotid or middle cerebral artery. MATERIALS AND METHODS This is a retrospective analysis of 58 consecutive patients who received low-dose eptifibatide (135-mcg/kg bolus, 1-mcg/kg/min infusion) during treatment of tandem occlusions. Brain imaging and carotid sonography were performed at 24-36 hours. mRS was documented at 90 days, and carotid sonography, at 30-60 days. RESULTS The median age and NIHSS score were 64 years and 15, respectively. Twenty-five patients (43%) received tPA. ASPECTSs were 8-10 in 47 (81%) and 5-7 in 11 (19%) patients. Thirty-eight patients had angioplasty/stent placement acutely; 20 had angioplasty alone. Symptomatic intracranial hemorrhage occurred in 1 patient (2%). TICI 2b or higher was achieved in 56 patients (96%). Fifty-seven of 58 patients had clinical follow-up at 90 days (1 lost to follow up). The 90-day mRS was 0-2 in 42 patients (72%). There were 4/58 (7%) re-occlusions within 24-36 hours, all originally treated with stent placement. Forty-nine of 53 surviving patients had carotid sonography at 30-60 days, with 3 delayed re-occlusions, 2 with stents and 1 with angioplasty alone. The overall carotid patency at 30-60 days was 42/49 (86%). Carotid re-occlusion was not associated with clinical decline. CONCLUSIONS Low-dose eptifibatide seemed to be safe in tandem occlusions (symptomatic intracranial hemorrhage, 2%), although asymptomatic cervical carotid artery re-occlusions still occurred in 14% of patients.

Abstract
Fewer than 1% of children diagnosed with diffuse-midline glioma (DMG) survive for more than 5 years, because no effective therapies exist for these patients. Here, we sought to identify and characterize mechanisms of aberrant splicing (AS) in primary DMG tumors. We observed transcriptome-wide AS (9,805 differential splicing variations in 4,734 genes), and identified a DMG-specific splicing signature, that included known cancer genes. We hypothesize that AS of cancer genes play a role in DMG tumor formation. Assessing whether splicing factor dysregulation impacted known cancer transcripts, we discovered several splicing factors, including SRRM4, SRRM3 and RBFOX3 to be down-regulated in DMG. Additionally, we found an enrichment of binding motifs for these proteins within flanking regions of these mis-spliced exons. We also observed recurrent significant exon inclusion in tumor suppressor SMARCA4, an integral member of the SWI/SNF family of proteins involved in chromatin remodeling. Further, we identified AS in 16 of the 27 members of the SWI/SNF complex, including increased skipping of exon 7 in DPF2, representing a complete mRNA transcript switch in DMG. Since SRRM4, SRRM3 and RBFOX3 are known regulators for neural-specific microexons, we focused on microexon splicing changes, hypothesizing that these regulators may be driving microexon mis-splicing in these tumors. We identified 245 known microexons lost or gained in DMG. Moreover, a quarter of which were observed in known cancer genes, with the most frequent splice event causing gain of a clathrin-binding site in the tumor suppressor BIN1 with a concurrent loss of an out-of-frame microexon in the oncogene BAK1, presumably activating it. Altogether, our results suggest that aberrant splicing may be an alternative mechanism driving DMG tumorigenesis and we are currently molecularly validating a subset of these events with the overall goal of identifying novel therapeutic targets for DMG tumors.

Abstract
In 2003, it was discovered that the entry receptor for the Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) is a protein called the angiotensin-converting enzyme 2 (ACE2). This protein is present in a number of cell types, including those from the respiratory tract. Soon after the emergence of SARS-CoV-2 that is responsible for the disease Covid-19, scientists found that ACE2 was also used by the new coronavirus to infect cells. This opened some interesting possibilities to explain the striking variation in risks of catching and dying from Covid-19. The best recognised of these are the much higher risk of serious illness in older than younger people, in men than women, and in those with pre-existing comorbidities such as hypertension and cardiovascular diseases. There are several ways in which the ACE2 protein might contribute to this variation. The most obvious would be if there is more ACE2, there would be more entry points for the virus to infect the cell, e.g. in older people or in men. However, the evidence for this is rather small, partly because it is not that easy to obtain representative healthy tissues. Alternatively, it could be related to ACE2 membership of a family of proteins that has one end of the protein anchored inside the cell while most of the protein protrudes from the outside of the cell which therefore can be shed when cleaved by proteases at the cell membrane. Herein we review current evidence and theories of ACE2 role on SARS-CoV-2 infectivity and Covid-19 severity.

Abstract
AIM To compare the frequency and factors associated with diabetes medication-taking (depression, perceived side effects, self-efficacy and social support) in people with mild to moderate intellectual disability and those without intellectual disability. METHODS In stage 1 of this study, we collated information on diabetes medication-taking and associated factors in 111 people with diabetes: 33 adults with mild to moderate intellectual disability and 78 adults without intellectual disability. Validated instruments measuring medicine-taking, self efficacy, depressive symptoms, perceived level of social support and perceived side effects were administered in both groups. In stage 2, we used an abductive qualitative approach to triangulate stage 1 findings with carers responses (n = 12). RESULTS The instruments showed good internal reliability (Cronbach's α = 0.7-0.9). Comparisons between people with intellectual disabilities and those without revealed similar frequency of medication-taking (70% vs 62%; P = 0.41). People with intellectual disabilities and diabetes had significantly higher depressive symptoms, as measured by the Glasgow Depression Scale for people with a Learning Disability (P = 0.04), higher levels of perceived side effects (P = 0.01), and lower confidence levels, as measured by the Perceived Confidence Scale (P = 0.01). The results of stage 2 showed how carers of people with intellectual disabilities and diabetes optimized medication-taking yet infrequently discussed the side effects of medicines. CONCLUSIONS Further investigation of medication-taking and side effects may result in the development of an evidence-informed intervention to improve medicines safety in people with intellectual disabilities.

Abstract
OBJECTIVE To develop a core outcome set for pre-eclampsia. DESIGN Consensus development study. SETTING International. POPULATION Two hundred and eight-one healthcare professionals, 41 researchers and 110 patients, representing 56 countries, participated. METHODS Modified Delphi method and Modified Nominal Group Technique. RESULTS A long-list of 116 potential core outcomes was developed by combining the outcomes reported in 79 pre-eclampsia trials with those derived from thematic analysis of 30 in-depth interviews of women with lived experience of pre-eclampsia. Forty-seven consensus outcomes were identified from the Delphi process following which 14 maternal and eight offspring core outcomes were agreed at the consensus development meeting. Maternal core outcomes: death, eclampsia, stroke, cortical blindness, retinal detachment, pulmonary oedema, acute kidney injury, liver haematoma or rupture, abruption, postpartum haemorrhage, raised liver enzymes, low platelets, admission to intensive care required, and intubation and ventilation. Offspring core outcomes: stillbirth, gestational age at delivery, birthweight, small-for-gestational-age, neonatal mortality, seizures, admission to neonatal unit required and respiratory support. CONCLUSIONS The core outcome set for pre-eclampsia should underpin future randomised trials and systematic reviews. Such implementation should ensure that future research holds the necessary reach and relevance to inform clinical practice, enhance women's care and improve the outcomes of pregnant women and their babies.

Abstract
Abstract
Background
Permanent school exclusion in Gateshead doubled from 2014 - 2017. A Behaviour Conference was held in July 2017 to formulate an action plan to curb this trend, including piloting 'Team around the School' (TAS). TAS is a local network of services, meeting on a regular basis to have shared conversations about pupils where early help may prevent escalation. Resources from several agencies are pooled to provide support for families, focusing on solutions and encouraging resilience.
Aim
To prevent future complex crisis interventions, reduce a 'refer on' culture, and align Early Help with school improvement.
Methods
The pilot ran at one Gateshead secondary school from January 2018 to July 2018. There were 17 TAS meetings during the pilot period. Four families, three referrers, six pupils and two managers were interviewed from 16th July - 3rd August 2018. Structured surveys, interviews and administrative data were used to determine effectiveness.
Results
Professionals viewed the programme as 'successful', however, there were some logistical issues, including gaining consent, capacity (physical rooms, funding and staffing) and integrating wider services into the programme. Pupils found the experience helpful and improved their overall health and wellbeing, at home and in school. Some saw dramatic improvements in attendance, presentation, attitude and behaviour, along with a more stable home life. Referrers were happy with the process and outcomes, finding TAS to be helpful in early intervention, with quick turnarounds. Families felt empowered, with improved communication and positive outcomes. Three plans were made, and three cases stepped up to Early Help. Four cases closed after reduction in risk. Two children moved schools.
Conclusions
TAS appears to successfully provide early support and intervention, reducing the risk of escalation, while also providing families with increased autonomy.
Key messages
A pupil's health and wellbeing is closely linked with their home life and life in school. Close agency working can improve a pupil's outcome in school and overall health and wellbeing.
