Emerging Variants of Canine Enteric Coronavirus Associated with Outbreaks of Gastroenteric Disease.

A 2022 canine gastroenteritis outbreak in the United Kingdom was associated with circulation of a new canine enteric coronavirus closely related to a 2020 variant with an additional spike gene recombination. The variants are unrelated to canine enteric coronavirus-like viruses associated with human disease but represent a model for coronavirus population adaptation.

Outbreak of Severe Vomiting in Dogs Associated with a Canine Enteric Coronavirus, United Kingdom.

The lack of population health surveillance for companion animal populations leaves them vulnerable to the effects of novel diseases without means of early detection. We present evidence on the effectiveness of a system that enabled early detection and rapid response a canine gastroenteritis outbreak in the United Kingdom. In January 2020, prolific vomiting among dogs was sporadically reported in the United Kingdom. Electronic health records from a nationwide sentinel network of veterinary practices confirmed a significant increase in dogs with signs of gastroenteric disease. Male dogs and dogs living with other vomiting dogs were more likely to be affected. Diet and vaccination status were not associated with the disease; however, a canine enteric coronavirus was significantly associated with illness. The system we describe potentially fills a gap in surveillance in neglected populations and could provide a blueprint for other countries.

Methods of Inactivation of SARS-CoV-2 for Downstream Biological Assays.

The scientific community has responded to the coronavirus disease 2019 (COVID-19) pandemic by rapidly undertaking research to find effective strategies to reduce the burden of this disease. Encouragingly, researchers from a diverse array of fields are collectively working towards this goal. Research with infectious severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is undertaken in high-containment laboratories; however, it is often desirable to work with samples at lower-containment levels. To facilitate the transfer of infectious samples from high-containment laboratories, we have tested methods commonly used to inactivate virus and prepare the sample for additional experiments. Incubation at 80°C, a range of detergents, Trizol reagents, and UV energies were successful at inactivating a high titer of SARS-CoV-2. Methanol and paraformaldehyde incubation of infected cells also inactivated the virus. These protocols can provide a framework for in-house inactivation of SARS-CoV-2 in other laboratories, ensuring the safe use of samples in lower-containment levels.

Improving access to care for women veterans suffering from chronic pain and depression associated with trauma.

OBJECTIVE: Access to care has become a priority for the Veterans Administration (VA) health care system as a significant number of veterans enrolled in the VA health care system reside in rural areas. The feasibility and effects of a novel clinical intervention that combined group therapy and biofeedback training was evaluated on women veterans living in rural areas. METHODS: The study was conducted at selected community-based outpatient clinics (CBOCs) in Texas. Thirty four women veterans with chronic pain and comorbid depression and/or posttraumatic stress disorder (PTSD) were recruited. Five sessions of education/therapy were delivered via telemedicine in combination with daily home practice of a portable biofeedback device (Stress Eraser®, Helicor, New York, NY, USA). Participants responded to self-report questionnaires at baseline, at posttreatment, and at 6-week follow-up. Daily practice logs were also maintained by participants. RESULTS: The clinical protocol was acceptable, easy to administer, and associated with statistically significant decreases in self-reported pain unpleasantness, pain interference, depressive symptoms, PTSD symptoms, and sleep disturbance at posttreatment. Improvements were maintained at 6-week follow-up. Qualitative analyses indicated that many participants 1) wished to continue to meet as a support group in their respective CBOCs and 2) felt less isolated and more empowered to cope with their problems of daily living as a result of the treatment. CONCLUSIONS: It is feasible to provide treatment to women veterans living in rural areas by utilizing video-teleconferencing technology between larger VA medical centers and facilities at CBOCs in more rural settings. A controlled trial of the intervention is warranted.

Safe administration of intravenous iron therapy.

This article describes the process of setting up a community service to meet the needs of patients with chronic kidney disease who have iron-deficiency anaemia. The service provides a course of intravenous (IV) iron therapy, which is usually given initially weekly for five weeks. Collaboration between specialist anaemia services in secondary care and the community IV therapy team in Liverpool aimed to develop a safe, patient-centred service. This service and the development of new medications has made the delivery of IV iron therapy in the community possible.

Suicide bereavement in the UK: Descriptive findings from a national survey.

BACKGROUND: Those bereaved by suicide are a high-risk group of adverse health outcomes and suicidal behavior, yet little is known about the experiences and support needs of these individuals in the UK. METHODS: We conducted a national cross-sectional study using an online survey and analyzed the experiences of 7158 participants who had been bereaved or affected by suicide. RESULTS: Suicide had a major impact on 77% of participants, including those who had lost a friend and those exposed to suicide at a professional level. Mental and physical health problems linked to the suicide were reported in half. Adverse social outcomes and engaging in high-risk behaviors following the suicide were common. Over a third reported suicidal ideation and 8% had attempted suicide as a direct result of the suicide loss. Most had not accessed support services, with the majority viewing provision of local suicide bereavement support as inadequate. CONCLUSIONS: Our results highlight the need for a multi-disciplinary approach in postvention and the provision of proactive outreach to support those bereaved by suicide. Postvention efforts need to acknowledge the death of a friend by suicide as a significant loss.

SARS-CoV-2 Infections in Animals: Reservoirs for Reverse Zoonosis and Models for Study.

The recent SARS-CoV-2 pandemic has brought many questions over the origin of the virus, the threat it poses to animals both in the wild and captivity, and the risks of a permanent viral reservoir developing in animals. Animal experiments have shown that a variety of animals can become infected with the virus. While coronaviruses have been known to infect animals for decades, the true intermediate host of the virus has not been identified, with no cases of SARS-CoV-2 in wild animals. The screening of wild, farmed, and domesticated animals is necessary to help us understand the virus and its origins and prevent future outbreaks of both COVID-19 and other diseases. There is intriguing evidence that farmed mink infections (acquired from humans) have led to infection of other farm workers in turn, with a recent outbreak of a mink variant in humans in Denmark. A thorough examination of the current knowledge and evidence of the ability of SARS-CoV-2 to infect different animal species is therefore vital to evaluate the threat of animal to human transmission and reverse zoonosis.

A virtual biobank for companion animals: A parvovirus pilot study.

BACKGROUND: There is a lack of national population data concerning infectious disease in companion animals. Here, we piloted the feasibility of linking diagnostic laboratories, population surveillance and modern sequencing approaches to extract targeted diagnostic samples from laboratories before they were discarded, as a novel route to better understand national epidemiology of major small animal pathogens. METHODS: Samples tested for canine or feline parvovirus were requested from a national veterinary diagnostic laboratory and analysed by Sanger or next generation sequencing. Samples were linked to electronic health data held in the SAVSNET database. RESULTS: Sequences obtained from positive samples, together with associated metadata, provided new insights into the recent geographical distribution of parvovirus strains in circulation in the United Kingdom (UK). CONCLUSIONS: This collaboration with industry represents a 'National Virtual Biobank' that can rapidly be called on, to efficiently add new layers of epidemiological information of relevance to animal, and potentially human, population health.

Ethnic Minority Groups' Experiences of Suicide Bereavement: A Qualitative Exploratory Study.

It is estimated that between 36,000 and 360,000 people are affected by suicide every year in the UK, and a proportion may develop depression and post-traumatic stress disorder, or engage in high-risk behaviours. Recent systematic analyses have revealed a clear gap in research on suicide bereavement in minority ethnic groups. This study aimed to understand the experiences and support needs of individuals from ethnic minority backgrounds bereaved by suicide and was the first in the UK to investigate this matter. The study was a secondary analysis of data. Participants were 7158 people residing in the UK who completed an online survey about their experiences of suicide. Free-text qualitative responses of 227 participants who did not identify as White British were analysed using thematic analysis. Four themes were identified: maladaptive coping strategies, emotional processes following suicide, lack of support from agencies, and the importance of mental health awareness. Ethnic minority groups reported a lack of support despite attempts to engage with services, noted the prevalence of stigma within ethnic minority groups, and expressed a need to tackle this. These preliminary results suggest that ethnic minority individuals require visible and accessible services that can successfully engage with and support them.

SARS-CoV-2 neutralising antibodies in Dogs and Cats in the United Kingdom.

Companion animals are susceptible to SARS-CoV-2 infection and sporadic cases of pet infections have occurred in the United Kingdom. Here we present the first large-scale serological survey of SARS-CoV-2 neutralising antibodies in dogs and cats in the UK. Results are reported for 688 sera (454 canine, 234 feline) collected by a large veterinary diagnostic laboratory for routine haematology during three time periods; pre-COVID-19 (January 2020), during the first wave of UK human infections (April-May 2020) and during the second wave of UK human infections (September 2020-February 2021). Both pre-COVID-19 sera and those from the first wave tested negative. However, in sera collected during the second wave, 1.4% (n=4) of dogs and 2.2% (n=2) cats tested positive for neutralising antibodies. The low numbers of animals testing positive suggests pet animals are unlikely to be a major reservoir for human infection in the UK. However, continued surveillance of in-contact susceptible animals should be performed as part of ongoing population health surveillance initiatives.

Temporal, Spatial, and Genomic Analyses of Enterobacteriaceae Clinical Antimicrobial Resistance in Companion Animals Reveals Phenotypes and Genotypes of One Health Concern.

BACKGROUND: Antimicrobial resistance (AMR) is a globally important one health threat. The impact of resistant infections on companion animals, and the potential public health implications of such infections, has not been widely explored, largely due to an absence of structured population-level data. OBJECTIVES: We aimed to efficiently capture and repurpose antimicrobial susceptibility test (AST) results data from several veterinary diagnostic laboratories (VDLs) across the United Kingdom to facilitate national companion animal clinical AMR surveillance. We also sought to harness and genotypically characterize isolates of potential AMR importance from these laboratories. METHODS: We summarized AST results for 29,330 canine and 8,279 feline Enterobacteriaceae isolates originating from companion animal clinical practice, performed between April 2016 and July 2018 from four VDLs, with submissions from 2,237 United Kingdom veterinary practice sites. RESULTS: Escherichia coli (E. coli) was the most commonly isolated Enterobacteriaceae in dogs (69.4% of AST results, 95% confidence interval, CI, 68.7-70.0) and cats (90.5%, CI 89.8-91.3). Multi-drug resistance was reported in 14.1% (CI 13.5-14.8) of canine and 12.0% (CI 11.1-12.9) of feline E. coli isolates. Referral practices were associated with increased E. coli 3rd generation ≤ cephalosporin resistance odds (dogs: odds ratio 2.0, CI 1.2-3.4). We selected 95 E. coli isolates for whole genome analyses, of which seven belonged to sequence type 131, also carrying the plasmid-associated extended spectrum ß-lactamase gene bla CTX-M- 15. The plasmid-mediated colistin resistance gene mcr-9 was also identified for the first time in companion animals. CONCLUSIONS: Linking clinical AMR data with genotypic characterization represents an efficient means of identifying important resistance trends in companion animals on a national scale.

Biochemical support for the "threshold" theory of creativity: a magnetic resonance spectroscopy study.

A broadly accepted definition of creativity refers to the production of something both novel and useful within a given social context. Studies of patients with neurological and psychiatric disorders and neuroimaging studies of healthy controls have each drawn attention to frontal and temporal lobe contributions to creativity. Based on previous magnetic resonance (MR) spectroscopy studies demonstrating relationships between cognitive ability and concentrations of N-acetyl-aspartate (NAA), a common neurometabolite, we hypothesized that NAA assessed in gray and white matter (from a supraventricular slab) would relate to laboratory measures of creativity. MR imaging and divergent thinking measures were obtained in a cohort of 56 healthy controls. Independent judges ranked the creative products of each participant, from which a "Composite Creativity Index" (CCI) was created. Different patterns of correlations between NAA and CCI were found in higher verbal ability versus lower verbal ability participants, providing neurobiological support for a critical "threshold" regarding the relationship between intelligence and creativity. To our knowledge, this is the first report assessing the relationship between brain chemistry and creative cognition, as measured with divergent thinking, in a cohort comprised exclusively of normal, healthy participants.

Neuroanatomy of creativity.

Creativity has long been a construct of interest to philosophers, psychologists and, more recently, neuroscientists. Recent efforts have focused on cognitive processes likely to be important to the manifestation of novelty and usefulness within a given social context. One such cognitive process - divergent thinking - is the process by which one extrapolates many possible answers to an initial stimulus or target data set. We sought to link well established measures of divergent thinking and creative achievement (Creative Achievement Questionnaire - CAQ) to cortical thickness in a cohort of young (23.7 +/- 4.2 years), healthy subjects. Three independent judges ranked the creative products of each subject using the consensual assessment technique (Amabile, 1982) from which a "composite creativity index" (CCI) was derived. Structural magnetic resonance imaging was obtained at 1.5 Tesla Siemens scanner. Cortical reconstruction and volumetric segmentation were performed with the FreeSurfer image analysis suite. A region within the lingual gyrus was negatively correlated with CCI; the right posterior cingulate correlated positively with the CCI. For the CAQ, lower left lateral orbitofrontal volume correlated with higher creative achievement; higher cortical thickness was related to higher scores on the CAQ in the right angular gyrus. This is the first study to link cortical thickness measures to psychometric measures of creativity. The distribution of brain regions, associated with both divergent thinking and creative achievement, suggests that cognitive control of information flow among brain areas may be critical to understanding creative cognition.

'We're the First Port of Call' - Perspectives of Ambulance Staff on Responding to Deaths by Suicide: A Qualitative Study.

INTRODUCTION: Exposure to suicide is a known risk factor for suicide. Ambulance staff are exposed to work-related stressors including attending suicides, which may elevate their risk for mental health problems/suicide. Little is known about ambulance staff's perspectives on how they experience these events and whether they feel equipped to respond to bereaved families at the scene of death. This study explores the perspectives of ambulance staff about responding to deaths by suicide. MATERIALS AND METHODS: A convenience sample of ambulance staff recruited from one ambulance service in England. In-depth, qualitative, semi-structured face-to-face interviews conducted with nine ambulance staff (six male, three female) to explore experiences of responding to suicide. Data analyzed using thematic analysis. RESULTS: Participants reported the experience of job-related strain including exposure to the suicide/suicidal ideation of colleagues; they described suppressing their distress despite significant emotional impact. All participants had been personally bereaved by suicide and responding to suicide was a common part of their job. They were often the first professionals at the scene, and undertook varied and often conflicting roles: negotiating with patients in crisis; informing individuals of the death of a loved one; preserving the body/potential crime scene; dealing with the intense emotional reactions of bereaved individuals. Participants reported long-term, salient memories of these events; however, there was a reported lack of acknowledgment in the workplace that suicides may be traumatic and no guidance for staff on how to cope. Opportunities to debrief were reportedly rare, and there was reluctance to access work-based liaison services. Training in how to respond to individuals bereaved by suicide was also lacking. DISCUSSION: The study is the first to reveal the complex challenges faced by ambulance staff in responding to suicide without adequate training and support. It demonstrates the potential impact that responding to suicide can have personally and professionally on staff, and emphasizes the need for employers to support staff wellbeing in better ways. Training and postvention support could enable better coping among staff, more effective support for bereaved individuals and reduce the risk of death by suicide both in those bereaved by suicide and in ambulance staff.

Experiences of support from primary care and perceived needs of parents bereaved by suicide: a qualitative study.

BACKGROUND: People bereaved by suicide are a vulnerable group, also at risk of dying by suicide. The importance of postvention support (intervention after suicide) has recently been highlighted; however, little is known about the support needs of parents bereaved by suicide in the UK, and the role played by general practice. AIM: To explore the perspectives, experiences, and support needs of parents bereaved by suicide. DESIGN AND SETTING: This was a qualitative study, with semi-structured interviews conducted between 2012 and 2014 in the north of England and the Midlands, with parents bereaved by their son or daughter's suicide. METHOD: Interviews explored parents' experiences of suicide bereavement following the death of their son or daughter, with a focus on their experiences of support from primary care. Interviews were analysed thematically using constant comparison. RESULTS: Twenty-three interviews were conducted. Three themes were identified from the data: the importance of not feeling alone; perceived barriers to accessing support; and the need for signposting for additional support. Some parents reported having experienced good support from their general practice; others described a number of barriers to accessing help, including triage processes. Primary care was considered to be an important avenue of support but GPs were often perceived as uncertain how to respond. The need for information, signposting to avenues of support, and the helpfulness of group support were also highlighted. CONCLUSION: Parents believed it was important that people working in general practice have an awareness of suicide bereavement and understanding of their needs, including knowledge of where to direct people for further support.

Evaluation of the Impact of the PABBS Suicide Bereavement Training on Clinicians' Knowledge and Skills.

Background: Health-care professionals do not routinely receive training on how best to support parents bereaved by suicide. Evidence-based training - Postvention Assisting Those Bereaved by Suicide (PABBS) - was designed to address this gap. Aims: The study aimed (a) to pilot PABBS training and evaluate its perceived effectiveness (impact on self-reported knowledge, skills and confidence) in managing suicide bereavement; and (b) to explore training acceptability. Method: A pre- and postevaluation design was used. Professionals attended intensive, structured 1-day PABBS training comprising: didactic/interactive teaching; practice-orientated activities supported with real-life materials and a manual/workbook. Evaluation forms completed immediately before and after training analyzed: (a) self-reported changes in knowledge, skills, and confidence (perceived effectiveness of training); and (b) the acceptability of training. Results: In total, 62 professionals completed training. Perceived knowledge, skills, and confidence improved after training as did self-reported understanding, motivation to learn more, and intention to change practice. Training was highly rated, particularly the evidence-based, real-life materials, with some suggestions for improvement. Limitations: Self-selected sample and reliance on self-report measures are the study's limitations. Conclusion: PABBS training may help address gaps in professionals' capacity to support parents bereaved by suicide. The evidence-based content was highly acceptable and appeared to be a key ingredient in effecting self-reported changes in attitudes/intentions.

Temporally separated feline calicivirus isolates do not cluster phylogenetically and are similarly neutralised by high-titre vaccine strain FCV-F9 antisera in vitro.

OBJECTIVES: Feline calicivirus (FCV) is a highly variable and globally important feline pathogen for which vaccination has been the mainstay of control. Here, we test whether the continued use of FCV-F9, one of the most frequently used vaccine strains globally, is driving the emergence of vaccine-resistant viruses in the field. METHODS: This study made use of two representative panels of field isolates previously collected from cats visiting randomly selected veterinary practices across the UK as part of separate cross-sectional studies from 2001 and 2013/2014. Phylogenetic analysis and in vitro virus neutralisation tests were used to compare the genetic and antigenic relationships between these populations and FCV-F9. RESULTS: Phylogenetic analysis showed a typically radial distribution dominated by 52 distinct strains, with strains from both 2001 and 2013/2014 intermingled. The sequence for FCV-F9 appeared to be integral to this phylogeny and there were no significant differences in the genetic distances within each studied population (intra-population distances), or between them (inter-population distances), or between each population and FCV-F9. A 1 in 8 dilution neutralised 97% and 100% of the 2001 and 2013/14 isolates, respectively, and a 1 in 16 dilution neutralised 87% and 75% of isolates, respectively. There was no significant difference either in variance between the FCV-F9 neutralising titres for the two populations, or in the distribution of neutralisation titres across the two populations. CONCLUSIONS AND RELEVANCE: Although FCV is a highly variable virus, we found no evidence for a progressive divergence of field virus from vaccine strain FCV-F9, either phylogenetically or antigenically, with FCV-F9 antisera remaining broadly and equally cross-reactive to two geographically representative and temporally separated FCV populations. We suggest this may be because the immunodominant region of the FCV capsid responsible for neutralisation may have structural constraints preventing its longer term progressive antigenic evolution.
