Abstract
Plants of the genus Lavandula are thought to be rarely infected by viruses. To date, only alfalfa mosaic virus, cucumber mosaic virus, tobacco mosaic virus, and tomato spotted wilt virus have been reported in this host. In this study, we identified for the first time raspberry ringspot virus (RpRSV) and phlox virus M (PhlVM) in lavender using herbaceous indexing, enzyme-linked immunosorbent assay, and high-throughput sequencing. Nearly complete genome sequences for both viruses were determined. Phylogenetic and serological characterizations suggest that the obtained RpRSV isolate is a raspberry strain. A preliminary survey of 166 samples indicated RpRSV was spread only in the lavender cultivar 'Grosso', while PhlVM was detected in multiple lavender cultivars. Although RpRSV raspberry strain may have spread throughout Auckland and nearby areas in New Zealand, it is very likely restricted to the genus Lavandula or even to the cultivar 'Grosso' due to the absence or limited occurrence of the nematode vector. Interestingly, all infected lavender plants, regardless of their infection status (by RpRSV, PhlVM, or both) were asymptomatic. RpRSV is an important virus that infects horticultural crops including grapevine, cherry, berry fruits, and rose. It remains on the list of regulated pests in New Zealand. RpRSV testing is mandatory for imported Fragaria, Prunus, Ribes, Rosa, Rubus, and Vitis nursery stock and seeds for sowing, while this is not required for Lavandula importation. Our study revealed that lavender could play a role not only as a reservoir but also as an uncontrolled import pathway of viruses that pose a threat to New Zealand's primary industries.

Abstract
BACKGROUND Depression, anxiety and PTSD appear to be risk factors for dementia, but it is unclear whether they are causal or prodromal. The inflammatory-mediated neurodegeneration hypothesis suggests a causal link, proposing that mental illness is associated with an inflammatory response which, in turn, triggers neurodegenerative changes that lead to dementia. Existing meta-analyses have yet to examine inflammatory markers in depression, anxiety or PTSD with the view to exploring the inflammatory-mediated neurodegeneration hypothesis. The current meta-analysis therefore examined whether: a) depression, anxiety and PTSD are individually associated with inflammation, independently of comorbid mental illnesses and physical health problems with known inflammatory responses, and b) there are any similarities in the inflammatory profiles of these disorders in order to provide a basis for exploring inflammation in people with dementia who have a history of clinically-significant anxiety, depression or PTSD. METHODS PubMed, EMBASE, PsycINFO and CINAHL searches identified 64 eligible studies. RESULTS Depression is associated with an inflammatory response, with tentative evidence to suggest anxiety and PTSD are also associated with inflammation. However, the specific response may differ across these disorders. LIMITATIONS The data for anxiety, PTSD and multiple inflammatory markers were limited. CONCLUSIONS Depression, anxiety, and PTSD each appear to be associated with an inflammatory response in persons who do not have comorbid mental or physical health problems that are known to be associated with inflammation. Whether this inflammatory response underlies the increased risk of dementia in persons with a history of depression and anxiety, and possibly PTSD, remains to be determined.

Abstract
In England, Cryphonectria parasitica was detected for the first time in 2011 in a nursery and in 2016 in the wider environment. Surveys between 2017 and 2020 identified the disease at different sites in Berkshire, Buckinghamshire, Cornwall, Derbyshire, Devon, Dorset, London, West Sussex, and the island of Jersey, while the present study comprises the results of the 2020-2023 survey with findings in Derbyshire, Devon, Kent, Nottinghamshire, Herefordshire, Leicestershire, London, West Sussex, and the islands of Jersey and Guernsey. A total of 226 suspected samples were collected from 72 surveyed sites, as far north as Edinburgh and as far west as Plymouth (both of which were negative), and 112 samples tested positive by real-time PCR and isolation from 35 sites. The 112 isolates were tested for the vegetative compatibility group (VCG), mating type, and Cryphonectria hypovirus 1 (CHV1). Twelve VCGs were identified, with two of them (EU-5 and EU-22) being the first records in the UK. Both mating types were present (37% MAT-1 and 63% MAT-2), but only one mating type was present per site and VCG, and perithecia were never observed. Cryphonectria hypovirus 1 (CHV1), consistently subtype-I haplotype E-5, was detected in three isolates at a low concentration (5.9, 21.1, and 33.0 ng/µL) from locations in London, Nottinghamshire, and Devon.

Abstract
Biological control of Cryphonectria parasitica fungus, the causal agent of chestnut blight, by virus infection (hypovirulence) is an effective control strategy against chestnut blight in Europe and some parts of North America. The most studied mycovirus is the Cryphonectria hypovirus 1 (CHV1) type species of the Hypoviridae family. In this study, the CHV1 virus was studied within some highly infected British isolates of Cryphonectria parasitica, gained in the past through co-culture transmissions. The effects of six temperatures (5-30 °C, in 5 °C steps) on six infected isolates (three with viral strain E-5, and other three with viral strain L-18) and their respective negative non-infected controls, three isogenic virulent fungal isolates, were examined. Experiments were performed with the nine isolate types with three replicates on potato dextrose agar (PDA) with cellophane sheets per isolate and temperature. A recently developed rapid, specific, quantitative reverse transcription PCR (RT-qPCR) screening method was used. This enabled quantifying the concentration (nanograms per microliter or copy numbers) of the virus within each isolate repetition. The presence of the virus had a significant negative effect between 20 and 25 °C on the C. parasitica growth rate, which was anyway highly influenced by and positively correlated with the temperature. The temperature clearly determined the virus accumulation and its recovery from cold or heat, and the virus optimum temperature was estimated at 15-25 °C.

Abstract
BACKGROUND Plasma p217+tau has shown high concordance with cerebrospinal fluid (CSF) and positron emission tomography (PET) measures of amyloid-β (Aβ) and tau in Alzheimer's Disease (AD). However, its association with longitudinal cognition and comparative performance to PET Aβ and tau in predicting cognitive decline are unknown. OBJECTIVES To evaluate whether p217+tau can predict the rate of cognitive decline observed over two-year average follow-up and compare this to prediction based on Aβ (18F-NAV4694) and tau (18F-MK6240) PET. We also explored the sample size required to detect a 30% slowing in cognitive decline in a 2-year trial and selection test cost using p217+tau (pT+) as compared to PET Aβ (A+) and tau (T+) with and without p217+tau pre-screening. DESIGN A prospective observational cohort study. SETTING Participants of the Australian Imaging, Biomarker and Lifestyle Flagship Study of Ageing (AIBL) and Australian Dementia Network (ADNeT). PARTICIPANTS 153 cognitively unimpaired (CU) and 50 cognitively impaired (CI) individuals. MEASUREMENTS Baseline p217+tau Simoa® assay, 18F-MK6240 tau-PET and 18F-NAV4694 Aβ-PET with neuropsychological follow-up (MMSE, CDR-SB, AIBL-PACC) over 2.4 ± 0.8 years. RESULTS In CI, p217+tau was a significant predictor of change in MMSE (β = -0.55, p < 0.001) and CDR-SB (β =0.61, p < 0.001) with an effect size similar to Aβ Centiloid (MMSE β = -0.48, p = 0.002; CDR-SB β = 0.43, p = 0.004) and meta-temporal (MetaT) tau SUVR (MMSE: β = -0.62, p < 0.001; CDR-SB: β = 0.65, p < 0.001). In CU, only MetaT tau SUVR was significantly associated with change in AIBL-PACC (β = -0.22, p = 0.008). Screening pT+ CI participants into a trial could lead to 24% reduction in sample size compared to screening with PET for A+ and 6-13% compared to screening with PET for T+ (different regions). This would translate to an 81-83% biomarker test cost-saving assuming the p217+tau test cost one-fifth of a PET scan. In a trial requiring PET A+ or T+, p217+tau pre-screening followed by PET in those who were pT+ would cost more in the CI group, compared to 26-38% biomarker test cost-saving in the CU. CONCLUSIONS Substantial cost reduction can be achieved using p217+tau alone to select participants with MCI or mild dementia for a clinical trial designed to slow cognitive decline over two years, compared to participant selection by PET. In pre-clinical AD trials, p217+tau provides significant cost-saving if used as a pre-screening measure for PET A+ or T+ but in MCI/mild dementia trials this may add to cost both in testing and in the increased number of participants needed for testing.

Abstract
BACKGROUND The arrival of the Delta variant of SARS-CoV-2 was associated with increased transmissibility and illness of greater severity. Reports of nosocomial outbreaks of Delta variant COVID-19 in acute care hospitals have been described but control measures varied widely. AIM Epidemiological investigation of a linked two-ward COVID-19 Delta variant outbreak was conducted to elucidate its source, risk factors, and control measures. METHODS Investigations included epidemiologic analysis, detailed case review serial SARS-CoV-2 reverse transcriptase-polymerase chain reaction (RT-PCR) testing of patients and healthcare workers (HCWs), viral culture, environmental swabbing, HCW-unaware personal protective equipment (PPE) audits, ventilation assessments, and the use of whole genome sequencing (WGS). FINDINGS This linked two-ward outbreak resulted in 17 patient and 12 HCW cases, despite an 83% vaccination rate. In this setting, suboptimal adherence and compliance to PPE protocols, suboptimal hand hygiene, multi-bedded rooms, and a contaminated vital signs cart with potential fomite or spread via the hands of HCWs were identified as significant risk factors for nosocomial COVID-19 infection. Sudden onset of symptoms, within 72 h, was observed in 79% of all Ward 2 patients, and 93% of all cases (patients and HCWs) on Ward 2 occurred within one incubation period, consistent with a point-source outbreak. RT-PCR assays showed low cycle threshold (CT) values, indicating high viral load from environmental swabs including the vital signs cart. WGS results with ≤3 SNP differences between specimens were observed. CONCLUSION Outbreaks on both wards settled rapidly, within 3 weeks, using a `back-to-basics' approach without extraordinary measures or changes to standard PPE requirements. Strict adherence to recommended PPE, hand hygiene, education, co-operation from HCWs, including testing and interviews, and additional measures such as limiting movement of patients and staff temporarily were all deemed to have contributed to prompt resolution of the outbreak.

Abstract
Abstract
Background
Many older people are brought to the Emergency Department (ED) who do not require acute hospital admission but there are risks to these patients if this occurs. The Frailty Intervention Team (FIT) are an interdisciplinary team based in the ED including physiotherapy, occupational therapy, speech and language therapy, dietetics, pharmacy, advanced nurse practitioners, and a geriatric registrar and consultant. They assess frail older patients and suggest alternative care pathways to admission. We aimed to investigate the impact of FIT on admission avoidance, bed days saved and to obtain patient feedback on their experience.
Methods
Routinely collected data from May 2021 to April 2022 was reviewed retrospectively. An anonymous patient feedback questionnaire was posted to 40 patients randomised from the FIT worklist between January to May 2022.
Results
2,025 Comprehensive Geriatric Assessments (CGA) were completed between May 2021 and April 2022. 38% percent of patients were discharged home, 45% of this number had follow-up arranged. 104 patients were transferred directly to an offsite bed, mostly rehabilitation. We estimate we avoided 51 admissions to the acute hospital per month, almost half of these were patients admitted to the hospital and, who we discharged to alternative care pathways or home. The average length of stay in April 2022 was 22 days – by avoiding 615 admissions between May 2021 and April 2022 we have saved 13,530 bed days at an estimated cost saving of almost €11 million. 15 completed questionnaires were returned. 73% were very satisfied with their experience. 87% felt the FIT team helped facilitate their discharge from ED. The main themes identified from open ended questions included thorough assessment, patient centred care and satisfaction with early intervention and discharge.
Conclusion
A Frailty Intervention Team is a cost effective and patient centred way of avoiding unnecessary admissions for older people presenting to the ED.

Abstract
Purpose Neonatal infections with SARS-CoV-2 are thought to be less contagious than in older children and adults. The transmission of SARS-CoV-2 from neonates and their environment has not been well studied. Droplet Digital PCR (ddPCR) is an emerging and sensitive technology that can aid infection control investigations. We sought to document surface contamination within the immediate environment of a preterm neonate with congenital COVID-19 using ddPCR. Methods & Materials On day 5 of life, a total of 23 environmental samples were collected in Eswabs (Amies media) based on proximity to the neonate, from the inside (7) and outside (16) of the neonate's incubator for ddPCR analysis. Samples were extracted, using an in-house method and each extract was run for reverse-transcription ddPCR measurement using the Bio-Rad SARS-CoV-2 ddPCR Kit. The 96-well RT-ddPCR ready plate was loaded into the QX200 Droplet Reader (Bio-Rad, Pleasanton, CA). The fluorescence intensity of each droplet was measured, and droplets were determined to be positive or negative for gene targets (N1, N2). Results All samples collected from outside of the incubator were negative.These included: a stethoscope hanging outside of the incubator, nearby keyboard/mouse, wireless phone receiver, barcode scanner, blood culture bottles, pens/pencils, light switches, weigh scale, countertop/shelf, cart with drawers and incubator port release clips. Samples collected from inside the incubator were positive for SARS-CoV-2. These results reported in copies per microlitre (cp/µL) extract included: the swaddle cloth (0.4 N2), sheets behind the neonate's head (11.4 N1, 16.9 N2), cardiorespiratory and saturation monitor leads and cables near the neonate's head (2.8 N1,4.5 N2), near the neonate's feet (2.1 N1, 3.7 N2), and nametags hanging on a panel (1.0 N1,1.2 N2). The highest levels were noted from the neonate's drool (25.2 N1, 35.2 N2). Conclusion The presence of SARS-CoV-2 was confirmed by ddPCR in environmental samples inside the incubator confirming the ability of the neonate to spread the virus in close quarters. No virus was identified outside of the incubator which suggests appropriate hand hygiene and disinfection of environmental surfaces. ddPCR appears to be a useful tool for investigating the potential role of fomites in COVID-19 transmission

Abstract
Background Coronavirus disease 2019 (COVID-19) has brought significant challenges to society globally, particularly in the area of healthcare provision. A pressing need existed in protecting those tasked with delivering healthcare solutions during the COVID-19 crisis by providing solutions for preserving adequate supplies of effective personal protective equipment (PPE). Aim To evaluate and validate available methods for the decontamination of N95 filtering facepiece respirators (FFRs) while maintaining functionality during re-use. Methods Multiple low-temperature steam and vaporized hydrogen peroxide (VHP) technologies were assessed for inactivation of Mycobacterium spp. and feline calicivirus (employed as representatives of the contamination challenge). Findings Virus (≥3log10) and Mycobacterium spp. (≥6log10) inactivation was achieved on various types of N95 FFRs using an array of heat (65–71oC), humidity (>50% relative humidity) and VHP without affecting the performance of the PPE. Conclusion The methods have been validated and were authorized by the US Food and Drug Administration under a temporary emergency use authorization. Based on the findings, opportunities exist for development and deployment of decontamination methods made from simple, general purpose materials and equipment should a future need arise.

Abstract
The FMR1 premutation (PM:55-199 CGG) is associated with fragile X-associated tremor/ataxia syndrome (FXTAS) and when maternally transmitted is at risk of expansion to a hypermethylated full mutation (FM: ≥ 200 CGG) that causes fragile X syndrome (FXS). We describe a maternally transmitted PM (77 CGG) that was passed to a son (103 CGG), and to a daughter (220-1822 CGG), who were affected with FXTAS and FXS, respectively. The male with the PM showed low-level mosaicism for normal size of 30 and 37 CGG. This male had two offspring: one female mosaic for PM and FM (56, 157, >200 CGG) and another with only a 37 CGG allele detected in multiple tissues, neither with a clinical phenotype. The female with the 37 CGG allele showed normal levels of FMR1 methylation and mRNA and passed this 37 CGG allele to one of her daughters, who was also unaffected. These findings show that post-zygotic paternal retraction can lead to low-level mosaicism for normal size alleles, with these normal alleles being functional when passed over two generations.

Abstract
BACKGROUND Depression, anxiety and PTSD appear to be linked to dementia, but it is unclear whether they are risk factors (causal or prodromal) for, comorbid with, or sequelae to (secondary effect of) dementia. Existing meta-analyses have examined depression or anxiety in all-cause dementia, Alzheimer's disease (AD) and vascular dementia (VaD), but have not considered post-traumatic stress disorder (PTSD), dementia with Lewy bodies (DLB), or frontotemporal dementia (FTD). The current meta-analysis examined the risk of developing dementia (AD, VaD, DLB, FTD, all-cause) in people with and without a history of clinically-significant depression, anxiety or PTSD in order to better understand the link between mental illness and dementia (PROSPERO number: CRD42018099872). METHODS PubMed, EMBASE, PsycINFO and CINAHL searches identified 36 eligible studies. RESULTS There is a higher risk of developing all-cause dementia and AD in people with previous depression, and a higher risk of all-cause dementia in people with prior anxiety, than in persons without this history. Prior PTSD was not associated with a higher risk of later being diagnosed with dementia. LIMITATIONS The data for anxiety, PTSD, DLB and FTD were limited. CONCLUSIONS Depression and anxiety appear to be risk factors for dementia, but longitudinal studies across adulthood (young adult/mid-life/older adult) are needed to evaluate the likely causal or prodromal nature of this risk. The link between PTSD and dementia remains unclear. Regular screening for new onset mental illness and for cognitive changes in older adults with a history of mental illness may assist with earlier identification of dementia.

Abstract
OBJECTIVES To determine the feasibility and tissue yield of a perinatal incisionless ultrasound-guided biopsy procedure, the INcisionless Targeted Core Tissue (INTACT) technique, in the context of minimally invasive autopsy. METHODS Cases of perinatal death in which the parents consented for minimally invasive autopsy underwent postmortem magnetic resonance imaging and an INTACT biopsy procedure, defined as needle biopsy of organs via the umbilical cord, performed under ultrasound guidance. In each case, three cores of tissue were obtained from seven target organs (both lungs, both kidneys, heart, spleen and liver). Biopsy success was predefined as an adequate volume of the intended target organ for pathological analysis, as judged by a pathologist blinded to the case and biopsy procedure. RESULTS Thirty fetuses underwent organ sampling. Mean gestational age was 30 weeks (range, 18-40 weeks) and mean delivery-to-biopsy interval was 12 days (range, 6-22 days). The overall biopsy success rate was 153/201 (76.1%) samples, with the success rates in individual organs being highest for the heart and lungs (93% and 91%, respectively) and lowest for the spleen (11%). Excluding splenic samples, the biopsy success rate was 150/173 (86.7%). Histological abnormalities were found in 4/201 (2%) samples, all of which occurred in the lungs and kidneys of a fetus with pulmonary hypoplasia and multicystic kidney disease. CONCLUSIONS Incisionless ultrasound-guided organ biopsy using the INTACT procedure is feasible, with an overall biopsy success rate of over 75%. This novel technique offers the ideal combination of an imaging-led autopsy with organ sampling for parents who decline the conventional invasive approach. © 2019 The Authors.

Abstract
Raspberry ringspot virus (RpRSV) is an important virus that infects horticultural crops including grapevine, cherry, berry fruit and rose. The genome sequences of RpRSV are highly diverse between isolates and this makes the design of a PCR-based detection method difficult. In this study, a TaqMan real-time RT-PCR assay was developed for the rapid and sensitive detection of RpRSV. Primers and probes targeting the most conserved region of the movement protein gene were designed to amplify a 229 bp fragment of RpRSV RNA-2. The assay was able to amplify all RpRSV isolates tested. The detection limit of the RpRSV target region was estimated to be 61-98 copies, depending on the RpRSV strain. The sensitivity was about 100 times greater than the conventional RT-PCR assay using the same primers as the real-time RT-PCR assay. A comparison with published conventional RT-PCR assays indicated that both published assays lacked reliability and sensitivity, as neither were able to amplify all RpRSV isolates tested, and both were at least 1000 times less sensitive than the novel TaqMan real-time RT-PCR assay. The assay can also be run as a duplex reaction with the nad5 plant internal control primers and probe to simultaneously verify the PCR competency of the samples. The amplicon obtained with the real-time RT-PCR assay is suitable for direct sequencing if it is necessary to further confirm the RpRSV identity or determine the RpRSV strain.

Abstract
BACKGROUND Poor oral health is largely preventable. Prevention includes toothbrushing and regular dental checks. Oral health has important consequences for general nutrition, chewing, communication, wider systemic disease, self-confidence and participation in society. This study investigated the prevalence of edentulousness (no natural teeth) in adults with intellectual disabilities (IDs) compared with the general population and associated factors. METHODS An adult cohort with IDs residing in Greater Glasgow and Clyde, Scotland, underwent detailed health assessments between 2002 and 2004. Between 2004 and 2006, a subsample had an oral check. Data on edentulousness in the cohort were compared with adult participants from Greater Glasgow and Clyde in the 2008 Scottish Health Survey. Within the IDs cohort, binary logistic regression analyses investigated potential relationships between edentulousness and demographic and clinical factors. RESULTS Five hundred sixty adults with IDs were examined [53.2% (298) male, mean age = 46.3 years, range 18-81 years] and compared with 2547 general population: edentulousness was 9% vs. 1% aged 25-34 years; 22% vs. 2% aged 35-44 years; 39% vs. 7% aged 45-54 years; 41% vs. 18% aged 55-64 years; and 76% vs. 34% aged 65-74 years. In both groups, edentulousness increased with age. After stratification for age, rates of edentulousness were consistently higher in the ID cohort. Odds ratios within age strata were not homogenous (Mantel-Haenszel test, P < 0.0001). Edentulousness was more likely in those with more severe IDs (adjusted odds ratio (AOR) = 2.36; 95% confidence interval (CI) [1.23 to 4.51]); those taking antipsychotics (AOR = 2.09; 95% CI [1.25 to 3.51]) and those living in the most deprived neighbourhoods (AOR = 2.69; 95% CI [1.11 to 6.50]). There was insufficient evidence for associations with sex, type of accommodation/support, antiepileptics, problem behaviours or autism. CONCLUSIONS Adults with IDs have a high prevalence of edentulousness and need supported daily oral care to reduce the need for extractions. Despite previous reports on poor oral care and the move towards person-centred care, carers and care-giving organisations need greater support to implement daily oral care. Prescribers need awareness of the potentially contributory role of antipsychotics, which may relate to xerostomia.

Abstract
OBJECTIVE Less invasive autopsy techniques in cases of fetal or infant death have good acceptability among parents, but the published sampling adequacy in needle biopsy studies is generally poor. Minimally Invasive Autopsy with Laparoscopically assisted sampling (MinImAL) has the potential to increase the diagnostic yield of less invasive autopsy by improving the quality and quantity of tissue samples obtained, whilst permitting visualization, extraction and examination of internal organs through a small incision. The aim of this study was to present the findings of our experience with the MinImAL procedure in cases of fetal, neonatal and pediatric death. METHODS This was a retrospective analysis of 103 prospectively recruited unselected cases of fetal, neonatal or pediatric death that underwent the MinImAL procedure at a tertiary referral center over a 5-year period. Following preprocedure 1.5-T whole-body postmortem magnetic resonance imaging, MinImAL autopsy was performed. Procedure duration, sampling adequacy and cause of death were assessed. Chi-square analysis was used to compare the 'unexplained' rate of intrauterine deaths in the cohort with that in a previously published cohort of > 1000 cases of intrauterine death examined by standard autopsy. RESULTS MinImAL autopsy was performed successfully in 97.8% (91/93) of the cases undergoing a complete procedure. There was a satisfactory rate of adequate histological sampling in most major organs; heart (100%, 91 cases), lung (100%, 91 cases), kidney (100%, 91 cases), liver (96.7%, 88 cases), spleen (94.5%, 86 cases), adrenal glands (89.0%, 81 cases), pancreas (82.4%, 75 cases) and thymus (56.0%, 51 cases). Procedure duration was similar to that of standard autopsy in a previously published cohort of intrauterine deaths. The unexplained rate in stillbirths and intrauterine fetal deaths that underwent MinImAL autopsy was not significantly different from that following standard autopsy. CONCLUSIONS The MinImAL procedure provides good histological yield from major organs with minimal cosmetic damage and can be learned by an autopsy practitioner. The MinImAL procedure is an appropriate minimally invasive alternative for the investigation of perinatal and pediatric deaths in which consent to full autopsy is withheld, and may have applications in both high- and low/middle-income settings.

Abstract
There appears to be a link between depression/anxiety/PTSD and dementia, although the evidence is incomplete and the reason is unclear. Mental illness may cause dementia or may be prodromal or comorbid with dementia, or dementia may trigger a relapse of symptoms in individuals with a history of mental illness. This study examined the link between depression/anxiety/PTSD and dementia by evaluating the prevalence of these disorders in people with dementia, relative to their healthy peers. Existing meta-analyses have examined the prevalence of clinically-significant depression and anxiety in Alzheimer's disease (AD), and depression in frontotemporal dementia (FTD), but have not considered vascular dementia (VaD), dementia with Lewy bodies (DLB), PTSD, or anxiety in FTD. The current meta-analysis compared the prevalence of clinically-significant depression, anxiety and PTSD in the four most common types of dementia (AD, VaD, DLB, FTD) and in unspecified dementia to that of healthy controls (PROSPERO number: CRD42017082086). PubMed, EMBASE, PsycINFO and CINAHL database searches identified 120 eligible studies. Prevalence rates were calculated for depression and anxiety in AD, VaD, DLB, FTD, unspecified dementia, and controls. PTSD data were only available for unspecified dementia. Subgroup analyses indicated that depression, but not anxiety, was more prevalent in people with dementia compared to controls; however, the anxiety analyses were probably under-powered. The results support a link between depression and dementia; however, the link between anxiety or PTSD and dementia remains unclear due to insufficient data. Longitudinal data is now needed to clarify whether depression/anxiety/PTSD may be risk factors for dementia.

Abstract
Background Detection and preventing entry of exotic viruses and viroids at the border is critical for protecting plant industries trade worldwide. Existing post entry quarantine screening protocols rely on time-consuming biological indicators and/or molecular assays that require knowledge of infecting viral pathogens. Plants have developed the ability to recognise and respond to viral infections through Dicer-like enzymes that cleave viral sequences into specific small RNA products. Many studies reported the use of a broad range of small RNAs encompassing the product sizes of several Dicer enzymes involved in distinct biological pathways. Here we optimise the assembly of viral sequences by using specific small RNA subsets. Results We sequenced the small RNA fractions of 21 plants held at quarantine glasshouse facilities in Australia and New Zealand. Benchmarking of several de novo assembler tools yielded SPAdes using a kmer of 19 to produce the best assembly outcomes. We also found that de novo assembly using 21–25 nt small RNAs can result in chimeric assemblies of viral sequences and plant host sequences. Such non-specific assemblies can be resolved by using 21–22 nt or 24 nt small RNAs subsets. Among the 21 selected samples, we identified contigs with sequence similarity to 18 viruses and 3 viroids in 13 samples. Most of the viruses were assembled using only 21–22 nt long virus-derived siRNAs (viRNAs), except for one Citrus endogenous pararetrovirus that was more efficiently assembled using 24 nt long viRNAs. All three viroids found in this study were fully assembled using either 21–22 nt or 24 nt viRNAs. Optimised analysis workflows were customised within the Yabi web-based analytical environment. We present a fully automated viral surveillance and diagnosis web-based bioinformatics toolkit that provides a flexible, user-friendly, robust and scalable interface for the discovery and diagnosis of viral pathogens. Conclusions We have implemented an automated viral surveillance and diagnosis (VSD) bioinformatics toolkit that produces improved viruses and viroid sequence assemblies. The VSD toolkit provides several optimised and reusable workflows applicable to distinct viral pathogens. We envisage that this resource will facilitate the surveillance and diagnosis viral pathogens in plants, insects and invertebrates.

Abstract
Complex relationships commonly exist between owners and their companion animals, particularly around feeding behaviour with an owner's affection or love for their animal most pronounced through the provision of food. It is notable that the pet food market is experiencing strong year-on-year growth in sales of dog and cat treats. Recognising the impact of treat giving in pet nutrition, the objective of the study was to investigate owner attitudes and motivations towards feeding treats (shop bought and other) to their dogs. A researcher-mediated questionnaire consisting of both quantitative and qualitative questions was used to interview dog owners (n=280) at two locations: an out-of-town retail park and a country park in the East Midlands. Owners almost unanimously viewed the word 'treat' within a nutritional context, as opposed to a new toy or other pleasure. The majority (96%) of owners interviewed reported feeding treats to their dog, with 69% feeding shop-bought treats on a daily basis. A wide range of treats was reportedly given by owners and the majority of owners interviewed fed multiple treat types. No association was found between owner age and frequency of shop-bought treats fed (P=0.659) nor between owner age and frequency of food given to the dog from the owner's plate (P=0.083). A wide range of foods which would not be considered balanced for the animal's nutritional requirements was viewed as a treat by some dog owners. A range of positive and negative views around the feeding of treats were expressed by dog owners, with some citing beneficial effects while others were clearly aware of the association between treat feeding and potential weight gain/obesity. Owner views included themes around positive reinforcement and responsibility but also reflected relational aspects of the human-animal bond. The results of the study show that treat giving is commonplace in feeding regimes and that treats are embedded in the feeding behaviour of many dog owners. However, the different views expressed around the motivations for, and feeding of, dog treats, reinforce the need to better understand owner psychology linked to this area, and the role this may play in the growing pet obesity epidemic.

Abstract
Red clover vein mosaic virus (RCVMV) is an important virus of leguminous crops that can cause devastating losses. During a routine survey of legumes conducted on the South Island of New Zealand, RCVMV was found in mixed infections in clover plants with Alfalfa mosaic virus and White clover mosaic virus. The full-length sequence of the New Zealand isolate RCVMV-NZ from clover shared 96% nucleotide sequence identity with a chickpea isolate previously described from Washington (United States). Targeted surveys of pea, faba bean, and pasture crops showed that RCVMV-NZ is widespread on the South Island in New Zealand. This isolate is causing mild if any symptoms on experimental hosts and naturally infected plants.

Some strains of Cherry leaf roll virus (CLRV) are considered as quarantine pests in New Zealand. CLRV was detected in seven plant host species: Actinidia chinensis, Hydrangea macrophylla, Malus domestica, Plantago major, Ribes rubrum, Rubus idaeus and Rumex sp. collected from New Zealand between 2005 and 2012. Biological, serological and molecular techniques were compared for the detection and differentiation of CLRV isolates. The biological analysis revealed differences in symptomatology and disease severity among the isolates. The five isolates tested by ELISA were serologically related to each other using polyclonal antisera with only one out of four commercially-available antisera successfully detecting all of them. The phylogenetic analysis of sequences obtained from parts of the coat protein, polymerase and 3'-untranslated regions revealed that the New Zealand CLRV isolates clustered into two closely related but distinct phylogenetic groups with some isolates grouping differently depending on the gene studied. The New Zealand CLRV isolates were clearly distinct to overseas isolates found in phylogenetic groups A, D and E. The conventional RT-PCR using primers targeting the CLRV coat protein coding region is recommended for determining sequence differences between strains. These findings will be useful in making regulatory decisions with regard to the testing requirements and the CLRV strains to be regulated in New Zealand.

Abstract
A novel virus, tentatively named "opium poppy mosaic virus" (OPMV), was isolated from Papaver somniferum (opium poppy) with leaf mosaic and mottling symptoms in Auckland, New Zealand, in 2006. The virus was mechanically transmitted to herbaceous plants of several species, in which it induced local and/or systemic symptoms. No virus particles were observed by electron microscopy in the diseased P. somniferum or any of the symptomatic herbaceous plants. The complete genomic sequence of 4230 nucleotides contains four open reading frames (ORF) and is most closely related (59.3 %) to tobacco bushy top virus, a member of the genus Umbravirus. These data suggest that OPMV is a new umbravirus.

Abstract
Hydrangea is a popular, summer flowering, ornamental shrub that is native to south and east Asia and North and South America, which is now cultivated throughout the world. Currently, 13 viruses belonging to eight genera have been reported in Hydrangea spp. (1). In April 2011, virus-like disease symptoms, including severe leaf deformation and chlorosis, were observed on two Hydrangea macrophylla 'Sumiko' plants from Australia being held in quarantine in New Zealand. Systemic symptoms of veinal necrosis, necrotic halo spots, and severe leaf deformation were observed on Nicotiana occidentalis '37B' 7 days after inoculation with sap from the symptomatic hydrangea plants. Upon reinoculation with sap of symptomatic leaves from N. occidentalis, necrotic ringspots and tip necrosis, typical of nepovirus infection, were observed on leaves of N. tobacum and Chenopodium quinoa, respectively. Transmission electron microscopy of negatively stained sap from symptomatic leaves of N. occidentalis revealed the presence of isometric particles ~28 nm in diameter. Total nucleic acid was extracted from the symptomatic leaves of N. occidentalis with an InviMag Plant DNA Mini Kit (Invitek GmbH, Berlin, Germany) and a KingFisher mL workstation (Thermo Scientific, Waltham, MA). Reverse transcription (RT)-PCR using the reverse primer of Werner et al. (2) and a forward primer, 5'-CGGTGGAGATGCCGGTCCTA-3' (this study), specific to the 3'-untranslated region (3'-UTR) of Cherry leaf roll virus(CLRV) produced an amplicon of ~1,150 bp from N. occidentalis. A consensus sequence of 1,140 bp generated from four clones of the PCR product (GenBank Accession No. JN418885) was 99 and 98% identical at the nucleotide level to a CLRV isolate from Rumex AGBC (GenBank No. AB168099) and Chinese chives (GenBank No. AB168098), respectively. N. occidentalis also tested positive for CLRV using polyclonal antiserum in a double antibody sandwich-ELISA (BIOREBA, Reinach, Switzerland). The presence of CLRV in the original samples and N. occidentalis was confirmed by direct sequencing of the 380-bp amplicons obtained by immunocapture RT-PCR using CLRV-specific primers (2) and the same antiserum. BLASTn analysis of these amplicons (data not submitted to GenBank) also showed 99% nucleotide identity to a New Zealand isolate from a Rubus sp. (GenBank No. AJ877162). The hydrangea plants were released from quarantine because the same strain of CLRV had previously been reported in New Zealand. To our knowledge, this is the first report of CLRV in hydrangea. CLRV is a seed and pollenborne nepovirus and can be transmitted mechanically and by grafting. Since hydrangeas are mainly vegetatively propagated and are less commonly grown from seeds, the natural spread of CLRV will depend on the movement of infected propagation material. It is unknown whether this virus causes reduction in flower quality in hydrangea as reported in other hosts but any impact on flower quality may be of economic significance in commercial nurseries.

Abstract
INTRODUCTION Nonlicensed allied health workers are becoming increasingly important in collaborative team care, yet we know little about their experiences while filling these roles. To explore their perceptions of working as health coaches in a chronic-disease collaborative team, the teamlet model, we conducted a qualitative study to understand the nature and dynamics of this emerging role. METHODS During semistructured interviews, 11 health coaches reflected on their yearlong experience in the teamlet model at an urban underserved primary care clinic. Investigators conducted a thematic analysis of transcriptions of the interviews using a grounded theory process. RESULTS Four themes emerged: 1) health-coach roles and responsibilities included acting as a patient liaison between visits, providing patient education and cultural brokering during medical visits, and helping patients navigate the health care system; 2) communication and relationships in the teamlet model of care were defined by a triad of the patient, health coach, and resident physician; 3) interest in the teamlet model was influenced by allied health workers' prior education and health care roles; and 4) factors influencing the effectiveness of the model were related to clinical and administrative time pressures and competing demands of other work responsibilities. CONCLUSION Nonlicensed allied health workers participating in collaborative teams have an important role in liaising between patients and their primary care physicians, advocating for patients through cultural brokering, and helping patients navigate the health care system. To maximize their job satisfaction, their selection should involve strong consideration of motivation to participate in these expanded roles, and protected time must be provided for them to carry out their responsibilities and optimize their effectiveness.

Abstract
CONTEXT The 15-minute office visit to primary care clinicians cannot meet the health care needs of patients. Innovation is needed to address this limitation, but practice redesign is challenging in clinical settings. OBJECTIVE Here we describe the implementation of a practice innovation, the teamlet model, in a San Francisco safety-net clinic. The teamlet consists of a clinician and "health coach" who expand the traditional medical visit into previsit, visit, postvisit, and between-visit care. DESIGN Teamlet implementation is occurring in phases. Phase 1 is evaluated using plan-do-study-act improvement cycles and interviews with a few patients, clinicians, and coaches. Phase 2 is evaluated using a pre- and postevent questionnaire, focused interviews, and focus groups with patients, faculty, clinicians, and coaches. MAIN OUTCOME MEASURES Phase 1: Plan-do-study-act cycles generate ideas to improve implementation. Phase 2 evaluation will query demographics, satisfaction, knowledge of self-management support, access, teamwork, and benefits/challenges of the teamlet model. Future research would measure objective clinical outcomes. RESULTS Phase 1 of the teamlet project led to useful adaptations, with anecdotal evidence that patients and clinicians were satisfied overall with practice improvements. Logistic problems made implementation of the innovation challenging. Phase 2 is currently underway, with results expected in 2008. CONCLUSIONS Primary care innovation requires multiple perspectives and constant revision. Traditional randomized controlled trials and quantitative evaluation designs are not appropriate for assessing practice-improvement pilot projects because projects must change and develop in their early stages. Despite numerous challenges, the teamlet practice redesign has the potential for improving on the traditional 15-minute physician's office visit.
