Capability, Opportunity, and Motivation-Identifying Constructs for Increasing Physical Activity Behaviours in Women with Polycystic Ovary Syndrome (PCOS).

Polycystic ovary syndrome (PCOS) is the commonest endocrinopathy in reproductive-aged women. Because increased adiposity is pivotal in the severity of PCOS-related symptoms, treatment usually incorporates increasing energy expenditure through physical activity (PA). This study aimed to understand the reasons why women with PCOS engage in PA/exercise, which could support the development of targeted behavioural interventions in this at-risk population. Validated questionnaires were administered for self-reported PA levels, quality of life, mental health, illness perception, sleep quality, and capability, opportunity, and motivation (COM) for PA. Using categorical PA data, outcomes were compared between groups; ordinal logistic regression (OLR) was used to identify whether COM could explain PA categorisation. A total of 333 participants were eligible; favourable differences were reported for body mass index, depression, mental wellbeing, self-rated health, illness perception, and insomnia severity for those reporting the highest PA levels. COM scores increased according to PA categorisation, whilst OLR identified conscious and automatic motivation as explaining the largest PA variance. The most active participants reported favourable data for most outcomes. However, determining whether health is protected by higher PA or ill health is a barrier to PA was not possible. These findings suggest that future behavioural interventions should be targeted at increasing patient motivation.

Digitally enabled flash glucose monitoring for inpatients with COVID-19: Feasibility and pilot implementation in a teaching NHS Hospital in the UK.

BACKGROUND: COVID-19 placed significant challenges on healthcare systems. People with diabetes are at high risk of severe COVID-19 with poor outcomes. We describe the first reported use of inpatient digital flash glucose monitoring devices in a UK NHS hospital to support management of people with diabetes hospitalized for COVID-19. METHODS: Inpatients at University Hospitals Coventry & Warwickshire (UHCW) NHS Trust with COVID-19 and diabetes were considered for digitally enabled flash glucose monitoring during their hospitalization. Glucose monitoring data were analysed, and potential associations were explored between relevant parameters, including time in hypoglycaemia, hyperglycaemia, and in range, glycated haemoglobin (HbA1c), average glucose, body mass index (BMI), and length of stay. RESULTS: During this pilot, digital flash glucose monitoring devices were offered to 25 inpatients, of whom 20 (type 2/type 1: 19/1; mean age: 70.6 years; mean HbA1c: 68.2 mmol/mol; mean BMI: 28.2 kg/m2) accepted and used these (80% uptake). In total, over 2788 h of flash glucose monitoring were recorded for these inpatients with COVID-19 and diabetes. Length of stay was not associated with any of the studied variables (all p-values >0.05). Percentage of time in hyperglycaemia exhibited significant associations with both percentage of time in hypoglycaemia and percentage of time in range, as well as with HbA1c (all p-values <0.05). The average glucose was significantly associated with percentage of time in hypoglycaemia, percentage of time in range, and HbA1c (all p-values <0.05). DISCUSSION: We report the first pilot inpatient use of digital flash glucose monitors in an NHS hospital to support care of inpatients with diabetes and COVID-19. Overall, there are strong arguments for the inpatient use of these devices in the COVID-19 setting, and the findings of this pilot demonstrate feasibility of this digitally enabled approach and support wider use for inpatients with diabetes and COVID-19.

Protein expression of transmembrane protease serine 4 in the gastrointestinal tract and in healthy, cancer, and SARS­CoV­2 infected lungs.

In addition to the angiotensin­converting enzyme 2 (ACE2), a number of host cell entry mediators have been identified for severe acute respiratory syndrome coronavirus­2 (SARS­CoV­2), including transmembrane protease serine 4 (TMPRSS4). The authors have recently demonstrated the upregulation of TMPRSS4 in 11 different cancers, as well as its specific expression within the central nervous system using in silico tools. The present study aimed to expand the initial observations and, using immunohistochemistry, TMPRSS4 protein expression in the gastrointestinal (GI) tract and lungs was further mapped. Immunohistochemistry was performed on tissue arrays and lung tissues of patients with non­small cell lung cancer with concurrent coronavirus disease 2019 (COVID­19) infection using TMPRSS4 antibody. The results revealed that TMPRSS4 was abundantly expressed in the oesophagus, stomach, small intestine, jejunum, ileum, colon, liver and pancreas. Moreover, the extensive TMPRSS4 protein expression in the lungs of a deceased patient with COVID­19 with chronic obstructive pulmonary disease and bronchial carcinoma, as well in the adjacent normal tissue, was demonstrated for the first time, at least to the best of our knowledge. On the whole, the immunohistochemistry data of the present study suggest that TMPRSS4 may be implicated in the broader (pulmonary and extra­pulmonary) COVID­19 symptomatology; thus, it may be responsible for the tropism of this coronavirus both in the GI tract and lungs.

Host cell entry mediators implicated in the cellular tropism of SARS­CoV­2, the pathophysiology of COVID­19 and the identification of microRNAs that can modulate the expression of these mediators (Review).

The pathophysiology of coronavirus disease 2019 (COVID­19) is mainly dependent on the underlying mechanisms that mediate the entry of severe acute respiratory syndrome coronavirus 2 (SARS­CoV­2) into the host cells of the various human tissues/organs. Recent studies have indicated a higher order of complexity of the mechanisms of infectivity, given that there is a wide­repertoire of possible cell entry mediators that appear to co­localise in a cell­ and tissue­specific manner. The present study provides an overview of the 'canonical' SARS­CoV­2 mediators, namely angiotensin converting enzyme 2, transmembrane protease serine 2 and 4, and neuropilin­1, expanding on the involvement of novel candidates, including glucose­regulated protein 78, basigin, kidney injury molecule­1, metabotropic glutamate receptor subtype 2, ADAM metallopeptidase domain 17 (also termed tumour necrosis factor­α convertase) and Toll­like receptor 4. Furthermore, emerging data indicate that changes in microRNA (miRNA/miR) expression levels in patients with COVID­19 are suggestive of further complexity in the regulation of these viral mediators. An in silico analysis revealed 160 candidate miRNAs with potential strong binding capacity in the aforementioned genes. Future studies should concentrate on elucidating the association between the cellular tropism of the SARS­CoV­2 cell entry mediators and the mechanisms through which they might affect the clinical outcome. Finally, the clinical utility as a biomarker or therapeutic target of miRNAs in the context of COVID­19 warrants further investigation.

Hyperbaric oxygen therapy for the treatment of long COVID: early evaluation of a highly promising intervention.

BACKGROUND: Long COVID is a common occurrence following COVID-19 infection. The most common symptom reported is fatigue. Limited interventional treatment options exist. We report the first evaluation of hyperbaric oxygen therapy (HBOT) for long COVID treatment. METHODS: A total of 10 consecutive patients received 10 sessions of HBOT to 2.4 atmospheres over 12 days. Each treatment session lasted 105 minutes, consisting of three 30-minute exposures to 100% oxygen, interspersed with 5-minute air breaks. Validated fatigue and cognitive scoring assessments were performed at day 1 and 10. Statistical analysis was with Wilcoxon signed-rank testing reported alongside effect sizes. RESULTS: HBOT yielded a statistically significant improvement in the Chalder fatigue scale (p=0.0059; d=1.75 (very large)), global cognition (p=0.0137; d=-1.07 (large)), executive function (p=0.0039; d=-1.06 (large)), attention (p=0.0020; d=-1.2 (very large)), information processing (p=0.0059; d=-1.25 (very large)) and verbal function (p=0.0098; d=-0.92 (large)). CONCLUSION: Long COVID-related fatigue can be debilitating, and may affect young people who were previously in economic employment. The results presented here suggest potential benefits of HBOT, with statistically significant results following 10 sessions.

Sleep Disruption and Depression, Stress and Anxiety Levels in Women With Polycystic Ovary Syndrome (PCOS) During the Lockdown Measures for COVID-19 in the UK.

Background: Lockdown measures have been enforced globally in response to the COVID-19 pandemic. Given the comorbidity burden in women with polycystic ovary syndrome (PCOS), these lockdown measures may have a particularly negative impact on sleep health, quality of life (QoL), and depression/stress levels in this population. The aim of this study was to explore whether such potential problems were present in women with PCOS during the COVID-19 lockdown in the UK. Methods: UK women with PCOS were recruited through social media into a cross-sectional study during the COVID-19 lockdown. The study survey was delivered online, and included demographic and COVID-19 relevant questions, as well as validated questionnaires/scales, namely the Insomnia Severity Index (ISI), Depression Anxiety and Stress Scale (DASS-21), and PCOSQOL questionnaire. Results: Three hundred and thirty-three women with PCOS [median age: 30.0 (9.0) years] were recruited. Participants were dichotomized based on responses regarding the impact of COVID-19 restrictions on their sleep [negative (N = 242) vs. no/positive (N = 91) impact]. No differences were noted between groups regarding age, time since PCOS diagnosis, body mass index, or number of comorbidities. Based on the ISI, 44.2% of participants reporting a negative impact on sleep exhibited at least moderately severe clinical insomnia. Compared to those who reported no/positive effect on sleep, the participants reporting a negative impact on sleep also reported poorer QoL, based on the total PCOSQOL score, with a greater impact of PCOS and poorer mood in the corresponding PCOSQOL domains. Based on the DASS-21, the latter also had statistically higher depression and stress levels compared to the former. Finally, for this cohort significant inverse correlations were noted between the ISI and PCOSQOL scores (total and domain scores), whilst the DASS-21 and ISI scores were positively correlated (all p-values <0.001). Conclusion: The majority of recruited UK women with PCOS reported that the COVID-19 lockdown had a negative impact on their sleep, which was also associated with impaired QoL and higher depression/stress levels. Whilst further research is required, women with PCOS should be considered a vulnerable population that may experience an adverse impact on sleep, QoL and mental health well-being due to lockdown measures during the COVID-19 pandemic.

Uncertainty, Anxiety and Isolation: Experiencing the COVID-19 Pandemic and Lockdown as a Woman with Polycystic Ovary Syndrome (PCOS).

Background: The COVID-19 pandemic and the related lockdown measures presented a significant risk to physical and mental wellbeing in affected populations. Women with polycystic ovary syndrome (PCOS) are predisposed to several cardio-metabolic risk factors which increase the susceptibility to severe COVID-19 and also exhibit increased likelihood of impaired mental health wellbeing. Therefore, these women who usually receive care from multiple primary and specialist healthcare services may be disproportionately impacted by this pandemic and the related restrictions. This study aimed to explore the lived experience of the first UK national lockdown as a woman with PCOS. Methods: As part of a larger cross-sectional study, 12 women with PCOS living in the UK during the first national COVID-19 lockdown were recruited to a qualitative study. Telephone interviews were conducted in June/July of 2020, and data collected were subjected to thematic analysis. Results: Five themes were identified. "My PCOS Journey" describes participants' experiences of diagnosis, treatment and ongoing management of their PCOS. "Living Through Lockdown" describes the overall experience and impact of the lockdown on all aspects of participants' lives. "Self-care and Managing Symptoms" describe multiple challenges to living well with PCOS during the lockdown, including lack of access to supplies and services, and disruption to weight management. "Healthcare on Hold" describes the uncertainty and anxiety associated with delays in accessing specialised healthcare for a range of PCOS aspects, including fertility treatment. "Exacerbating Existing Issues" captures the worsening of pre-existing mental health issues, and an increase in health anxiety and feelings of isolation. Conclusion: For the women with PCOS in this study, the COVID-19 pandemic and the first national lockdown was mostly experienced as adding to the pre-existing challenges of living with their condition. The mental health impact experienced by the study participants was increased due to lack of access to their normal support strategies, limitations on healthcare services and uncertainty about their risk of COVID-19.

Healthcare Staff Perceptions Following Inoculation with the BNT162b2 mRNA COVID-19 Vaccine at University Hospitals Coventry & Warwickshire NHS Trust.

Background: COVID-19 vaccination programmes offer hope for a potential end to the acute phase of the COVID-19 pandemic. We present perceptions following from a cohort of healthcare staff at the UK NHS hospital, which first initiated the BNT162b2 mRNA COVID-19 ("Pfizer") vaccination program. Methods: A paper-based survey regarding perceptions on the BNT162b2 mRNA COVID-19 vaccine was distributed to all healthcare workers at the University Hospitals Coventry & Warwickshire NHS Trust following receipt of the first vaccine dose. Results: 535 healthcare workers completed the survey, with a 40.9% response rate. Staff felt privileged to receive a COVID-19 vaccine. Staff reported that they had minimised contact with patients with confirmed or suspected COVID-19. Reported changes to activity following vaccination both at work and outside work were guarded. Statistically significant differences were noted between information sources used by staff groups and between groups of different ethnic backgrounds to inform decisions to receive vaccination. Conclusions: NHS staff felt privileged to receive the COVID-19 vaccine, and felt that their actions would promote uptake in the wider population. Concerns regarding risks and side effects existed, but were minimal. This research can be used to help inform strategies driving wider vaccine uptake amongst healthcare staff and the public.

Introduction of a novel COVID-19 biomarker panel by coventry and warwickshire pathology services (CWPS)

COVID-19 is heterogeneous in presentation, with cough, fever, dyspnoea and in some cases, acute respiratory distress syndrome documented. Confidence in the interpretation of clinical symptoms and management of patients can be enhanced with the use of biomarkers and could provide clinicians with a tool to predict prognosis and mortality, allowing for earlier interventions and optimal resource allocation.In March 2020, clinicians approached CWPS requesting the provision of biomarkers, as highlighted in early publications. The aim of this change was to improve the clinical management of patients, remove the need for referral laboratory testing and ensure swift translation of recent evidence into clinical practice. Cost, method availability, IT requirements, assay verification, sample needs and appropriate testing were all considered when extending the scope of service. Continued dialogue with those leading the local COVID clinical pathway ensured the change was clinically supported and that testing was incorporated into the trust ward management strategies.Royal College of Pathology guidelines later published in April 2020 supported the service change and literature reviews continue to highlight the role of inflammatory markers for patient stratification;with a recent systematic review finding some of the included biomarkers increased in more severe infections. The Association of Clinical Biochemistry have also made a statement encouraging this type of innovation, utilising both scientific and medical staff in the improvement of patient care.In collaboration with statisticians from local universities, biomarker data is being interrogated so that any findings may be translated into practice. Currently, multiple regression analysis has allowed the creation of models to explain association of analytes with outcomes and it is hoped continued work will allow the creation of decisions trees and clinical reference values.

Understanding the lived experience of redeployed consultant physicians in the COVID-19 pandemic: essential information for leaders of future pandemics and emergencies

A key challenge early in the COVID-19 pandemic was to identify staff able to meet the demand for senior medical assessment of an influx of acutely unwell respiratory patients. At UHCW we proposed that specialist physicians without recent general medicine experience could be safely and effectively redeployed to support the acute medical take.A rota of consultant physicians from 8 medical specialties, who did not participate in the acute medical take, was developed at pace to work alongside the medical registrar, in the segregated respiratory area of ED, following limited training. Two shifts were implemented within 6 days of inception, fitted around doctors’ ongoing specialty roles.We gained feedback iteratively during the early phases. We then used a survey of all those asked to redeploy to explore their lived experiences and perceptions, with a 71% response rate.Median time since consultants had participated in an unselected medical take was 12 years. 66% were not GIM accredited. 84% found the online training useful. Many had concerns regarding availability of PPE and the risk of passing infection on to others, including their own vulnerable patients. 81% described concerns around personal competence.63% of respondents felt this redeployment had made a positive difference to the COVID-19 response. However, 57% felt other groups should have been redeployed before them, and 45% reported they would not agree to be redeployed in a repeat scenario. Transparency regarding who was redeployed and equity amongst all physicians were the most important factors influencing decisions on future redeployment.We rapidly implemented a consultant redeployment programme during the pandemic, and redeployed doctors felt they made a positive difference. However, the same staff group may not willingly be redeployed during any future emergency. We hope this open and honest approach to collecting feedback will help to shape local and national planning for future major incidents

Differential perceptions regarding personal protective equipment use during the COVID-19 pandemic by NHS healthcare professionals based on ethnicity, sex and professional experience.

OBJECTIVES: To capture perceptions regarding personal protective equipment (PPE) among healthcare professionals during the COVID-19 pandemic, including staff subgroups at high risk for severe COVID-19, such as black and minority ethnic (BAME) groups. DESIGN: Electronically distributed survey with semi-quantitative analysis. Survey distributed at a major academic NHS tertiary referral centre in the West Midlands with a diverse medical workforce to medically qualified staff who completed COVID-19 redeployment training. (N=121; 47% female; 49% of BAME background; 26% international medical graduates). RESULTS: All demographic groups reported overall good awareness of when and how to use PPE during COVID-19 pandemic. Statistically significant differences in the perceptions regarding PPE use during COVID-19 were noted between BAME vs non-BAME staff, international vs UK medical graduates, and male vs female participants, as well as between professionals at different stages of their career. The differences related to perceptions around availability, degree of protection provided, perceived inconvenience, ability to raise concerns about availability, confidence in sharing underlying health conditions with managers and the impact of full PPE in emergency situations causing delay patient care. CONCLUSIONS: Amongst medically qualified staff, significant differences exist in the perceptions relating to the, availability and effectiveness of PPE during the COVID-19 pandemic depending on country of training, ethnic background and sex. GAFREC STUDY APPROVAL: Study ID GF0392.

Changes in Physical Activity and Sedentary Behaviour Due to Enforced COVID-19-Related Lockdown and Movement Restrictions: A Protocol for a Systematic Review and Meta-Analysis.

Prolonged lockdown/restriction measures due to the COVID-19 pandemic have reportedly impacted opportunities to be physically active for a large proportion of the population in affected countries globally. The exact changes to physical activity and sedentary behaviours due to these measures have not been fully studied. Accordingly, the objective of this PROSPERO-registered systematic review is to evaluate the available evidence on physical activity and sedentary behaviours in the general population during COVID-19-related lockdown/restriction measures, compared to prior to restrictions being in place. Defined searches to identify eligible studies published in English, from November 2019 up to the date of submission, will be conducted using the following databases: CENTRAL, MEDLINE, EMBASE, CINAHL, SPORTDiscus, PSYCinfo, Coronavirus Research Database, Public Health Database, Publicly Available Content Database, SCOPUS, and Google Scholar. The applied inclusion criteria were selected to identify observational studies with no restrictions placed on participants, with outcomes regarding physical activity and/or sedentary behaviour during lockdown/restriction measures, and with comparisons for these outcomes to a time when no such measures were in place. Where appropriate, results from included studies will be pooled and effect estimates will be presented in random effects meta-analyses. To the best of our knowledge, this will be the first systematic review to evaluate one complete year of published data on the impact of COVID-19-related lockdown/restriction measures on physical activity and sedentary behaviour. Thus, this systematic review and meta-analysis will constitute the most up-to-date synthesis of published evidence on any such documented changes, and so will comprehensively inform clinical practitioners, public health agencies, researchers, policymakers and the general public regarding the effects of lockdown/restriction measures on both physical activity and sedentary behaviour.

COVID­19 and SARS­CoV­2 host cell entry mediators: Expression profiling of TMRSS4 in health and disease.

Severe acute respiratory syndrome (SARS) coronavirus­2 (SARS­CoV­2), the causative viral agent for the ongoing COVID­19 pandemic, enters its host cells primarily via the binding of the SARS­CoV­2 spike (S) proteins to the angiotensin­converting enzyme 2 (ACE2). A number of other cell entry mediators have also been identified, including neuropilin­1 (NRP1) and transmembrane protease serine 2 (TMPRSS2). More recently, it has been demonstrated that transmembrane protease serine 4 (TMPRSS4) along with TMPRSS2 activate the SARS­CoV­2 S proteins, and enhance the viral infection of human small intestinal enterocytes. To date, a systematic analysis of TMPRSS4 in health and disease is lacking. In the present study, using in silico tools, the gene expression and genetic alteration of TMPRSS4 were analysed across numerous tumours and compared to controls. The observations were also expanded to the level of the central nervous system (CNS). The findings revealed that TMPRSS4 was overexpressed in 11 types of cancer, including lung adenocarcinoma, lung squamous cell carcinoma, cervical squamous cell carcinoma, thyroid carcinoma, ovarian cancer, cancer of the rectum, pancreatic cancer, colon and stomach adenocarcinoma, uterine carcinosarcoma and uterine corpus endometrial carcinoma, whilst it was significantly downregulated in kidney carcinomas, acute myeloid leukaemia, skin cutaneous melanoma and testicular germ cell tumours. Finally, a high TMPRSS4 expression was documented in the olfactory tubercle, paraolfactory gyrus and frontal operculum, all brain regions which are associated with the sense of smell and taste. Collectively, these data suggest that TMPRSS4 may play a role in COVID­19 symptomatology as another SARS­CoV­2 host cell entry mediator responsible for the tropism of this coronavirus both in the periphery and the CNS.

Impact of the COVID-19 pandemic on neuroendocrine tumour services in England.

PURPOSE: During the COVID-19 pandemic, there have been particular concerns regarding the related impact on specialist tumour services. Neuroendocrine tumour (NET) services are delivered in a highly specialised setting, typically delivered in a small number of centres that fulfil specific criteria as defined by the European Neuroendocrine Tumour Society (ENETS). We aimed to address the COVID-19-related impact on specialist NET tumour services in England and other countries. METHODS: Electronic survey addressing patient access and delivery of care distributed to all ENETS Centres of Excellence (CoE) in England and matching number of ENETS CoE elsewhere. Semi-quantitative and qualitative analyses of survey responses were performed. RESULTS: Survey response of ENETS CoE in England was 55% (6/11). Responses from six non-UK ENETS CoE elsewhere were received and analysed in a similar manner. Relevant disruption of various NET services was noted across all responding Centres, which included delayed patient appointments and investigations, reduced availability of treatment modalities including delayed surgical treatment and a major negative impact on research activities. The comparison between English and non-UK ENETS CoE suggested that the former had significantly greater concerns related to future research funding (p = 0.014), whilst having less disruption to multidisciplinary meetings (p = 0.01). A trend was also noted towards virtual patient appointments in ENETS CoE in England vs. elsewhere (p = 0.092). CONCLUSIONS: Restoration of highly specialised NET services following COVID-19 and planning for future service delivery and research funding must take account of the severe challenges encountered during the pandemic.

Is There a Link between Bisphenol A (BPA), a Key Endocrine Disruptor, and the Risk for SARS-CoV-2 Infection and Severe COVID-19?

Infection by the severe acute respiratory syndrome (SARS) coronavirus-2 (SARS-CoV-2) is the causative agent of a new disease (COVID-19). The risk of severe COVID-19 is increased by certain underlying comorbidities, including asthma, cancer, cardiovascular disease, hypertension, diabetes, and obesity. Notably, exposure to hormonally active chemicals called endocrine-disrupting chemicals (EDCs) can promote such cardio-metabolic diseases, endocrine-related cancers, and immune system dysregulation and thus, may also be linked to higher risk of severe COVID-19. Bisphenol A (BPA) is among the most common EDCs and exerts its effects via receptors which are widely distributed in human tissues, including nuclear oestrogen receptors (ERα and ERß), membrane-bound oestrogen receptor (G protein-coupled receptor 30; GPR30), and human nuclear receptor oestrogen-related receptor gamma. As such, this paper focuses on the potential role of BPA in promoting comorbidities associated with severe COVID-19, as well as on potential BPA-induced effects on key SARS-CoV-2 infection mediators, such as angiotensin-converting enzyme 2 (ACE2) and transmembrane serine protease 2 (TMPRSS2). Interestingly, GPR30 appears to exhibit greater co-localisation with TMPRSS2 in key tissues like lung and prostate, suggesting that BPA exposure may impact on the local expression of these SARS-CoV-2 infection mediators. Overall, the potential role of BPA on the risk and severity of COVID-19 merits further investigation.

Managing high-acuity outpatient services during the COVID-19 pandemic: lessons from the acute diabetes foot service.

COVID-19 has created unprecedented challenges for healthcare services internationally. Many NHS organisations have cancelled outpatient clinics to release frontline clinical staff and minimise risk of patients contracting COVID-19. While many outpatient services manage chronic diseases, a number of services manage high-acuity patients. Delivery of these acute outpatient services during the pandemic has posed particular challenges and required significant service model reconfiguration. The acute diabetes foot clinic is an important example of such a service. We explore the important lessons learnt during the COVID-19 pandemic for managing high-acuity outpatient services through the context of the diabetic foot clinic. Learning can be divided into the following categories: remote and digital working, physical changes in service delivery, workforce challenges and post-pandemic preparedness. This learning is applicable to a wide range of high-acuity services during and following the pandemic. It is particularly relevant as we expand outpatient care provision to avoid hospital admissions.

Rising to the challenge: Qualitative assessment of medical student perceptions responding to the COVID-19 pandemic.

BACKGROUND: Medical students internationally have volunteered and stepped up to support frontline clinical teams during the COVID-19 pandemic. We know very little about the motivation of those volunteering, or their concerns in deploying to a new role. We aim to establish the reasons that medical students volunteered in one Trust and understand to their concerns. METHODS: Structured survey, thematic analysis and categorisation of volunteer student perceptions. RESULTS: Medical students volunteered for broadly four reasons: to make a contribution, to learn, to benefit from remuneration and for an activity during the national lockdown. There were disparate concerns; however, the most common involved availability of personal protective equipment, uncertainty as to expectations and becoming infected. CONCLUSIONS: We must recognise and applaud the motivations of our future workforce who have stepped up to support the NHS at a time of unprecedented demand. The experiences and learning gained during this period will undoubtedly shape their future medical training and careers.

Neuropilin­1 as a new potential SARS­CoV­2 infection mediator implicated in the neurologic features and central nervous system involvement of COVID­19.

Infection by the severe acute respiratory syndrome (SARS) coronavirus­2 (SARS­CoV­2) is the cause of the new viral infectious disease (coronavirus disease 2019; COVID­19). Emerging evidence indicates that COVID­19 may be associated with a wide spectrum of neurological symptoms and complications with central nervous system (CNS) involvement. It is now well­established that entry of SARS­CoV­2 into host cells is facilitated by its spike proteins mainly through binding to the angiotensin­converting enzyme 2 (ACE­2). Preclinical studies have suggested that neuropilin­1 (NRP1), which is a transmembrane receptor that lacks a cytosolic protein kinase domain and exhibits high expression in the respiratory and olfactory epithelium, may also be implicated in COVID­19 by enhancing the entry of SARS­CoV­2 into the brain through the olfactory epithelium. In the present study, we expand on these findings and demonstrate that the NRP1 is also expressed in the CNS, including olfactory­related regions such as the olfactory tubercles and paraolfactory gyri. This furthers supports the potential role of NRP1 as an additional SARS­CoV­2 infection mediator implicated in the neurologic manifestations of COVID­19. Accordingly, the neurotropism of SARS­CoV­2 via NRP1­expressing cells in the CNS merits further investigation.
