Abstract
Members of the enterovirus genus are promising oncolytic agents. Their morphogenesis involves the generation of both genome-packed infectious capsids and empty capsids. The latter are typically considered as an impurity in need of removal from the final product. The separation of empty and full capsids can take place with centrifugation methods, which are of low throughput and poorly scalable, or scalable chromatographic processes, which typically require peak cutting and a significant trade-off between purity and yield. Here we demonstrate the application of packed bed cation exchange (CEX) column chromatography for the separation of empty capsids from infectious virions for a prototype strain of Coxsackievirus A21. This separation was developed using high throughput chromatography techniques and scaled up as a bind and elute polishing step. The separation was robust over a wide range of operating conditions and returned highly resolved empty and full capsids. The CEX step could be operated in bind and elute or flowthrough mode with similar selectivity and returned yields greater than 70% for full mature virus particles. Similar performance was also achieved using a selection of other bead based CEX chromatography media, demonstrating general applicability of this type of chromatography for Coxsackievirus A21 purification. These results highlight the wide applicability and excellent performance of CEX chromatography for the purification of enteroviruses, such as Coxsackievirus A21.

Abstract
INTRODUCTION Little is known about global variation in early epidemic growth rates and effective reproduction numbers (Re) of seasonal influenza. We aimed to estimate global variation in Re of influenza type A and B during a single period. METHODS Country influenza detection time series from September 2017 through January 2019 were obtained from an international database. Type A and B epidemics by country were selected based on Re estimates for a five-week moving window advanced by week. Associations of Re with absolute latitude, Human Development Index, percent of the population aged <15 years and percent living rurally in each country were assessed. RESULTS Time series were included for 119 of 169 available countries. There were 100 countries with influenza A and 79 with B epidemics. Median Re for both influenza A and B epidemics was 1.23 (ranges: A 1.10, 1.60; B 1.06, 1.58). Re of influenza B, but not A, was independently associated with absolute latitude, increasing by 0.022 (95% CI 0.002, 0.043) per 10 degrees. CONCLUSIONS Re of influenza A and B were similar. Only Re of influenza B was associated with country characteristics; increasing with distance from the equator. The approach may be suitable for continuous Re surveillance.

Abstract
Person-centred care (PCC) and shared decision-making (SDM) are part of national clinical standards for an increasing number of areas of health care delivery. In addition to existing standards for accrediting hospitals, day surgery facilities, public dental services and medical education in Australia, new standards governing primary health care and digital mental health services have been added. Implementation and measurement of PCC and SDM to comply with standards, and training of health professionals, remain challenges for the Australian health sector. Consumer involvement in health research, policy and clinical service governance continues to increase and the National Health and Medical Research Council has begun to encourage consumer and community involvement in health and medical research. This increased consumer engagement and moves towards more PCC provision is reflected in a focus on encouraging patients to ask questions during their clinical care and supports improvements in consumer health literacy. SDM support tools are now being culturally adapted whilst a need for more systemic approaches to their development and implementation persists. With increasing resources and tools for all aspects of PCC and SDM challenges to find sustainable solutions to ensure tools are kept up to date with the best available evidence remain.

Abstract
Rare disease patients are more likely to receive a rapid molecular diagnosis nowadays thanks to the wide adoption of next generation sequencing. However, many cases remain undiagnosed even after exome or genome analysis, because the methods used missed the molecular cause in a known gene, or a novel causative gene could not be identified and/or confirmed. To address these challenges, the RD-Connect Genome-Phenome Analysis Platform (GPAP) facilitates the collation, discovery, sharing and analysis of standardised genome-phenome data within a collaborative environment. Authorised clinicians and researchers submit pseudonymised phenotypic profiles encoded using the Human Phenotype Ontology, and raw genomic data which is processed through a standardised pipeline. After an optional embargo period, the data is shared with other platform users, with the objective that similar cases in the system and queries from peers may help diagnose the case. Additionally, the platform enables bidirectional discovery of similar cases in other databases from the Matchmaker Exchange network. To facilitate genome-phenome analysis and interpretation by clinical researchers, the RD-Connect GPAP provides a powerful user-friendly interface and leverages tens of information sources. As a result, the resource has already helped diagnose hundreds of rare disease patients and discover new disease causing genes. This article is protected by copyright. All rights reserved.

Abstract
PURPOSE Oral cancers lack standardized monitoring systems. Our institution has developed an active surveillance system which provides detailed monitoring and follow up of patients with oral preneoplastic lesions (OPL). We examined a historic cohort of patients with OPL seen by regional dental professionals and a current cohort of clinic patients. The major aim was to examine follow up practices for biopsy proven dysplasia to gauge appropriateness of an active monitoring system for oral carcinoma. MATERIALS AND METHODS Questionnaires regarding patients with OPL were sent to 285 dentists who had requested oral pathology services from our institution. The follow up practices of 141 dentists were evaluated for patients with OPL. We then examined our current clinic referral patterns for the number of dental referrals after the creation of an oral carcinoma active surveillance clinic. RESULTS There were 76.5% (108/141) of patients who received follow up after diagnosis of preneoplastic oral lesions with 14.1% who underwent repeat biopsy. There was a malignant transformation rate of 11.3% including transformation of 42.8% of severe dysplasias into carcinoma within 2 years. After establishment of a dental referral clinic, 21.8% of tumor visits in a six-week period were referred from the regional dental community. CONCLUSIONS A high rate of transformation of OPL to cancer in this cohort may support a role for joint dental and otolaryngology surveillance of dysplasia with longitudinal follow up.

Abstract
Background Many countries remain in the grip of the COVID-19 global pandemic, with a considerable journey still ahead toward normalcy and free mobility. Contact tracing smartphone apps are among a raft of measures introduced to reduce spread of the virus, but their uptake depends on public choice. Objective The objective of this study was to ascertain the views of citizens in Wales on their intended use of a COVID-19 contact tracing smartphone app, including self-proposed reasons for or against use and what could lead to a change of decision. Methods We distributed an anonymous survey among 4000 HealthWise Wales participants in May 2020. We adopted a mixed methods approach: responses to closed questions were analyzed using descriptive and inferential statistics; open question responses were analyzed and grouped into categories. Results A total of 976 (24.4%) people completed the survey. Smartphone usage was 91.5% overall, but this varied among age groups. In total, 97.1% were aware of contact tracing apps, but only 67.2% felt sufficiently informed. Furthermore, 55.7% intended to use an app, 23.3% refused, and 21.0% were unsure. The top reasons for app use were as follows: controlling the spread of the virus, mitigating risks for others and for oneself, and increasing freedoms. The top reasons against app use were as follows: mistrusting the government, concerns about data security and privacy, and doubts about efficacy. The top response for changing one’s mind about app use from being willing to being unwilling was that nothing would; that is, they felt that nothing would cause them to become unwilling to use a contact tracing app. This was also the top response for changing one’s mind from being unwilling to being willing to use contact tracing apps. Among those who were unsure of using contact tracing apps, the top response was the need for more information. Conclusions Respondents demonstrated a keenness to help themselves, others, society, and the government to avoid contracting the virus and to control its spread. However, digital inclusion varied among age groups, precluding participation for some people. Nonetheless, unwillingness was significant, and considering the nature of the concerns raised and the perceived lack of information, policy and decision-makers need to do more to act openly, increase communication, and demonstrate trustworthiness if members of the public are to be confident in using an app.

Abstract
OBJECTIVES To present phenotype features of a large cohort of congenital myasthenic syndromes (CMS) and correlate them with their molecular diagnosis. METHODS Suspected CMS patients were divided into three groups: group A (limb, bulbar or axial weakness, with or without ocular impairment, and all the following: clinical fatigability, electrophysiology compatible with neuromuscular junction involvement and anticholinesterase agents response), group B (limb, bulbar or axial weakness, with or without ocular impairment, and at least one of additional characteristics noted in group A) and group C (pure ocular syndrome). Individual clinical findings and the clinical groups were compared between the group with a confirmed molecular diagnosis of CMS and the group without molecular diagnosis or with a non-CMS molecular diagnosis. RESULTS Seventy-nine patients (68 families) were included in the cohort: 48 in group A, 23 in group B and 8 in group C. Fifty-one were considered confirmed CMS (30 CHRNE, 5 RAPSN, 4 COL13A1, 3 DOK7, 3 COLQ, 2 GFPT1, 1 CHAT, 1 SCN4A, 1 GMPPB, 1 CHRNA1), 7 probable CMS, 5 non-CMS and 16 unsolved. The chance of a confirmed molecular diagnosis of CMS was significantly higher for group A and lower for group C. Some individual clinical features, alterations on biopsy and electrophysiology enhanced specificity for CMS. Muscle imaging showed at least mild alterations in the majority of confirmed cases, with preferential involvement of soleus, especially in CHRNE CMS. CONCLUSIONS Stricter clinical criteria increase the chance of confirming a CMS diagnosis, but may lose sensitivity, especially for some specific genes.

Abstract
Objective: Black men are three times more likely to develop prostate cancer (PCa), to do so at a younger age and to experience a more aggressive form than White men. This study aims to understand the experiences of African-Caribbean men with respect to their discharge to primary care following successful PCa treatment and the challenges associated with survivorship.Design: Eight African-Caribbean men, who had been successfully treated for PCa, were recruited through the charity BME Cancer Communities. They participated in a focus group, which took place on the premises of the charity and was audio-recorded. The recording was transcribed and the data were analysed employing thematic analysis.Results: Three overarching themes were developed: Discharge - misconceptions and uncertainties; Survivorship - challenges and ways of coping; Black men and PCa: real and potential discrimination. Participants expressed concerns regarding the lack of information and clarity about what discharge meant, the quality of follow-up care, especially the levels of specialist knowledge among GPs, and the impact of side-effects, particularly erectile dysfunction (ED). Participants linked ED with stereotypes of Black male sexuality, particularly in relation to difficulties of expressing their emotions and psychological distress. African-Caribbean men face particular challenges in dealing with the side-effects of treatment for PCa, which are linked to socially-constructed ideas of masculinity.Conclusion: There needs to be a greater focus in primary care on understanding these issues and providing individualised culturally-sensitive care. In particular, GPs should be aware of sensitivities concerning help-seeking related to culturally-mediated understandings of masculinity.

Abstract
Abstract
Background
The WHO Europe Region consists of 53 countries, each of which has differences in mortality from cardiovascular (CVD), neurological, and chronic respiratory diseases. Such diverse metrics result from political, social, and economic events that have influenced the health performance of each European sub-region. From a public health perspective, an updated analysis of such metrics is required for policymakers and health system organisations to improve the overall population health outcomes.
Methods
This study utilised data between 1990-2017 from the Global Burden of Disease study 2017 to explore the association between GDP and NCD mortality in Western, Central, and Eastern Europe and Central Asia. The mortality data was already stratified by age and sex, and a fixed effected regression analysis was run to observe associations between both variables using STATA. Data completeness was 80-100% for GDP and 100% for mortality across the European region. The final results were reported as a rate per 100,000, with confidence intervals. The rate changes were calculated using an equation from the GBD.
Results
The most significant decrease per 100,000 of the population across all three NCDs as GDP increased was in Central Asia and Eastern Europe among both sexes. For every 1000 unit increase in GDP, we expect -12.13 [-13.60, -10.66] and -14.49 [-16.89, -12.29] less deaths in CVD in females and males per 100,000 of population, respectively. Western Europe had the lowest decrease per 100,000 of the population, as with every 1000 unit increase in GDP, we expect -2.42 [-2.59, -2.25] and -4.09 [-4.33, -3.84] fewer deaths in CVD in females and males, respectively.
Conclusions
The overall differential rate of mortality from the three NCDs is decreasing across all regions. However, there is a large disparity between the sexes. Males have a higher mortality rate across CVD and chronic respiratory diseases, whilst neurological disorders were highest among females.
Key messages
This study’s analysis has added to existing knowledge on chronic health patterns in the WHO European region. Governments in Eastern Europe and Central Asia should introduce health policies targeting unhealthy consumption of alcohol, smoking and diets, as seen in Western Europe.

Abstract
INTRODUCTION Data from the Association of American Medical Colleges' Medical School Graduation Questionnaire show persistent trends of medical student mistreatment nationwide. To reduce the barriers and increase actionable reporting of mistreatment, we integrated peer-facilitated learning environment sessions led by a group of trained third- and fourth-year medical students in all core clinical clerkships. METHODS During the 2018-2019 academic year, third-year medical students were recruited, oriented, and trained to act as facilitators of sessions on mistreatment. The sessions occurred once every clerkship block, using a standardized session introduction and guide. After a 6-month pilot, new medical students were recruited and worked as scribe/facilitator pairs, receiving an additional 1.5-hour training midyear, which was evaluated with a postworkshop survey. RESULTS Thirty-eight students implemented 43 peer-facilitated sessions and completed deidentified minutes of each session, which were shared with clerkship directors and the Medical Education Office for review. Survey data from midyear facilitator training indicated that facilitators highly agreed peer-led sessions were an important avenue for students to process experiences of mistreatment (3.9 out of 4), understood barriers to reporting (3.8 out of 4) and definitions of mistreatment (3.6 out of 4), and felt confident to facilitate these sessions (3.6 out of 4). DISCUSSION Peer-facilitated sessions offer a method to learn more about student experiences with mistreatment in real time and create a new avenue for communication between faculty and students. Assembling a stable core team of third- and fourth-year students trained in facilitation skills ensures the sustainability and relevance of the program.

Abstract
OBJECTIVE Is the level of shared decision-making (SDM) higher after introduction of a SDM package (including encounter decision aids on treatment options for heavy menstrual bleeding and training for clinicians) than before?. METHODS This before-after study, performed in OB-GYN practice, compared consultations before and after introduction of a SDM package. The target sample size was 25 patients per group. Women seeking treatment for heavy menstrual bleeding were eligible. After their appointments, patients filled out a three-item patient-reported SDM measure. Treatment discussions were audio-recorded and rated for SDM using Observer OPTION5. Consultation transcripts in the 'after' group were checked for adherence to the steps required for intended use of decision aids. RESULTS 16 gynaecologists participated. 25 patients participated before introduction of the decision aids and 28 after. The proportion of women reporting optimal SDM was higher after introduction (75 %) than before (50 %;p < 0.001). The mean observer-rated level of SDM was also significantly higher after than before (MD = 12.50,95 % CI 5.53-19.47). CONCLUSION The level of SDM was higher after the introduction of the package than before. PRACTICE IMPLICATIONS This study was conducted in a real-life setting in three clinics, both large academic and small rural, offering opportunities for implementation in different type of organizations.

Abstract
Diagnosing uncommon diseases in individuals with underlying medical conditions can be challenging. Cognitive bias can lead to delayed or missed disease management. We present a case of Shiga-toxin mediated hemolytic uremic syndrome (ST-HUS) in a 46-year-old man with ulcerative colitis and alcohol use disorder who presented with acute alcohol intoxication, non-bloody diarrhoea and coffee ground emesis. He was admitted to the hospital for alcoholic ketoacidosis, alcohol withdrawal and possible upper gastrointestinal bleed, but ultimately, he developed severe thrombocytopaenia, hemolytic anaemia, acute renal failure and prolonged altered mentation. Given that ST-HUS is uncommon in adults, his initial report of diarrhoea was attributed to alcohol use or underlying active ulcerative colitis and not connected to his haematologic abnormalities. He was initially started on plasmapheresis; however, thrombotic microangiopathy work up revealed Shiga-toxin in his stool and ADAMST13 levels within normal limits. Subsequently, he was transitioned to supportive care for management of ST-HUS.

Abstract
Within human modified ecosystems the effects of individual stressors are difficult to establish amid co-occurring biological processes, environmental gradients and other stressors. Coupled examination of several endpoints across different levels of organisation may help elucidate the individual and combined effects of stressors and interactions. Malathion is a commonly used organophosphate pesticide that contaminates freshwaters and has strong negative effects on aquatic biota. However, both other stressors (e.g. increased sediment) and common ecosystem components (e.g. macrophytes and variable pH) can reduce the aqueous concentrations of malathion, reducing its toxic effects. We conducted a fully orthogonal bioassay to examine how pH (at 7 and 7.8) and sorptive processes (across two levels of kaoline clay 0 and 24 g L-1) affected aqueous malathion concentrations and toxicity in an aquatic invertebrate genus. Survival and acetylcholinesterase activity as a sub-organism response were examined in the mayfly Coloburiscoides spp. (Ephemeroptera; Coluburiscidae). Measured aqueous malathion concentrations decreased with increased pH and in the presence of kaolin clay. Survival declined with increasing malathion concentrations and exposure period. Results further identify that antagonism of malathion toxicity was associated with both pH (alkaline hydrolysis) and effects associated with sediment independent of pH (driven by sorptive processes). However, model predictions varied associated with target and measured concentrations and concentrations examined. Antagonistic effects were most apparent using subset target malathion concentrations because of the dominant effect of malathion at high concentrations. Acetylcholinesterase activity, identified repression occurred across all treatments and did not identify antagonistic interactions, but these results were similar to survival responses at the time points examined (i.e. 120 h). Examination of chemistry, acetylcholinesterase, and survival, affords greater understanding of stressor effects and their interactions. Measured malathion concentrations may underestimate effects on aquatic biota; not because of synergism among stressors, but because of strong effects despite antagonism.

Abstract
The trimeric severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein (S) is the sole viral protein responsible for both viral binding to a host cell and the membrane fusion event needed for cell entry. In addition to facilitating fusion needed for viral entry, S can also drive cell-cell fusion, a pathogenic effect observed in the lungs of SARS-CoV-2-infected patients. While several studies have investigated S requirements involved in viral particle entry, examination of S stability and factors involved in S cell-cell fusion remain limited. A furin cleavage site at the border between the S1 and S2 subunits (S1/S2) has been identified, along with putative cathepsin L and transmembrane serine protease 2 cleavage sites within S2. We demonstrate that S must be processed at the S1/S2 border in order to mediate cell-cell fusion and that mutations at potential cleavage sites within the S2 subunit alter S processing at the S1/S2 border, thus preventing cell-cell fusion. We also identify residues within the internal fusion peptide and the cytoplasmic tail that modulate S-mediated cell-cell fusion. In addition, we examined S stability and protein cleavage kinetics in a variety of mammalian cell lines, including a bat cell line related to the likely reservoir species for SARS-CoV-2, and provide evidence that proteolytic processing alters the stability of the S trimer. This work therefore offers insight into S stability, proteolytic processing, and factors that mediate S cell-cell fusion, all of which help give a more comprehensive understanding of this high-profile therapeutic target.

Abstract
INTRODUCTION The goal of neuromuscular scoliosis (NMS) surgery is to improve sitting balance, facilitate daily care, and alleviate pain. In nonambulatory patients, where sitting balance is key, fusion to the pelvis is usually required. However, in minimally ambulatory patients, fusion to the pelvis remains controversial, and there is considerable practice variability in this patient population. The purpose of this study is to evaluate and summarize the available evidence regarding fusion constructs in minimally ambulatory patients with NMS and to provide expert opinion regarding when fusion to the pelvis should be considered. METHODS A search of the English literature was performed using PubMed to identify papers pertaining to patients with NMS treated with instrumented posterior spinal fusion. Papers published before 2000, case reports, and level V evidence were excluded. RESULTS The authors identified 8 studies for review. The majority included both nonambulatory and minimally ambulatory patients. Structured review of the literature demonstrated fusion to the pelvis may allow for greater curve and pelvic obliquity correction, but it is also associated with increased blood loss and operative time. There is no evidence that fusing to the pelvis decreases ambulatory status in minimally ambulatory patients. CONCLUSIONS In minimally ambulatory patients with NMS, fusion short of the pelvis may be considered in patients with adequate head control without the presence of hip subluxation or dislocation and when pelvic obliquity is <15 degrees. Fusion to the pelvis is recommended in patients who do not meet these criteria.

Abstract
ABSTRACT The aim of this study was to compare outcomes for single-event multilevel surgery (SEMLS) in cerebral palsy (CP) performed by 1 or 2 attending surgeons.A retrospective review of patients with CP undergoing SEMLS was performed. Patients undergoing SEMLS performed by a single senior surgeon were compared with patients undergoing SEMLS by the same senior surgeon and a consistent second attending surgeon. Due to heterogeneity of the type and quantity of SEMLS procedures included in this study, a scoring system was utilized to stratify patients to low and high surgical burden. The SEMLS events scoring less than 18 points were categorized as low burden surgery and SEMLS scoring 18 or more points were categorized as high burden surgery. Operative time, estimated blood loss, hospital length of stay, and operating room (OR) utilization costs were compared.In low burden SEMLS, 10 patients had SEMLS performed by a single surgeon and 8 patients had SEMLS performed by 2 surgeons. In high burden SEMLS, 10 patients had SEMLS performed by a single surgeon and 12 patients had SEMLS performed by 2 surgeons. For high burden SEMLS, operative time was decreased by a mean of 69 minutes in cases performed by 2 co-surgeons (P = 0.03). Decreased operative time was associated with an estimated savings of $2484 per SEMLS case. In low burden SEMLS, a trend toward decreased operative time was associated for cases performed by 2 co-surgeons (182 vs 221 minutes, P = 0.11). Decreased operative time was associated with an estimated savings of $1404 per low burden SEMLS case. No difference was found for estimated blood loss or hospital length of stay between groups in high and low burden SEMLS.Employing 2 attending surgeons in SEMLS decreased operative time and OR utilization cost, particularly in patients with a high surgical burden. These findings support the practice of utilizing 2 attending surgeons for SEMLS in patients with CP.Level of Evidence: Level III.
