Forecasting daily total pollen concentrations on a global scale.

BACKGROUND: There is evidence that global anthropogenic climate change may be impacting floral phenology and the temporal and spatial characteristics of aero-allergenic pollen. Given the extent of current and future climate uncertainty, there is a need to strengthen predictive pollen forecasts. METHODS: The study aims to use CatBoost (CB) and deep learning (DL) models for predicting the daily total pollen concentration up to 14 days in advance for 23 cities, covering all five continents. The model includes the projected environmental parameters, recent concentrations (1, 2 and 4 weeks), and the past environmental explanatory variables, and their future values. RESULTS: The best pollen forecasts include Mexico City (R2(DL_7) ≈ .7), and Santiago (R2(DL_7) ≈ .8) for the 7th forecast day, respectively; while the weakest pollen forecasts are made for Brisbane (R2(DL_7) ≈ .4) and Seoul (R2(DL_7) ≈ .1) for the 7th forecast day. The global order of the five most important environmental variables in determining the daily total pollen concentrations is, in decreasing order: the past daily total pollen concentration, future 2 m temperature, past 2 m temperature, past soil temperature in 28-100 cm depth, and past soil temperature in 0-7 cm depth. City-related clusters of the most similar distribution of feature importance values of the environmental variables only slightly change on consecutive forecast days for Caxias do Sul, Cape Town, Brisbane, and Mexico City, while they often change for Sydney, Santiago, and Busan. CONCLUSIONS: This new knowledge of the ecological relationships of the most remarkable variables importance for pollen forecast models according to clusters, cities and forecast days is important for developing and improving the accuracy of airborne pollen forecasts.

Influence of Preterm Birth and Environmental Context on Academic Performance and Neurodevelopmental Outcomes.

BACKGROUND: Preterm birth affects 10% of all births annually in the United States. Outcomes of people born preterm are challenging to predict because of multiple influences, including gestational age, birth weight, and social and environmental contexts, that contribute to an individual's growth and developmental trajectory. The influence of toxic stress is underrepresented in the literature assessing preterm birth outcomes. OBJECTIVES: The current analyses use the eco-bio-developmental model of poverty and preterm birth as a framework to model the pathways among toxic stress, preterm birth, and neurodevelopmental outcomes. Poverty and toxic stress were hypothesized to increase the risk for impaired neurodevelopmental and academic outcomes-both directly and indirectly. METHODS: The analytic sample of 55,873 children aged 6-17 years was derived from the National Survey of Children's Health 2020-2021. Structural equation models with combined measurement and path models for each dependent variable were constructed using latent toxic stress variables. The structural path equations included direct paths from the latent measure of prenatal toxic stress, preterm birth status, and the latent measure of childhood toxic stress to the neurodevelopmental outcome, as well as an indirect, mediated path from prenatal toxic stress through preterm birth status to the outcome. RESULTS: Across models, higher levels of prenatal toxic stress were significantly associated with preterm birth and lower birth weight ranges. Preterm low birth weight status was associated with a greater likelihood of neurodevelopmental impairment, repeating a grade, and special education plans. The predicted probabilities of neurodevelopmental impairment, repeating grades, and special education plans are significantly higher with above-average levels of exposure to prenatal and childhood toxic stress. DISCUSSION: There is a need for prospective studies that assess predictors and outcomes of preterm birth that are stratified by gestational age and consider the timing, chronicity, and influence of toxic stress and environmental exposures. There is an imperative for public health programs and policies designed to support families, caregivers, and children to address the individual and structural social determinants of health that contribute to toxic stress, thereby increasing preterm birth rates and negatively affecting the outcomes of children born preterm.

Evaluation of a Natural Language Processing Approach to Identify Diagnostic Errors and Analysis of Safety Learning System Case Review Data: Retrospective Cohort Study.

BACKGROUND: Diagnostic errors are an underappreciated cause of preventable mortality in hospitals and pose a risk for severe patient harm and increase hospital length of stay. OBJECTIVE: This study aims to explore the potential of machine learning and natural language processing techniques in improving diagnostic safety surveillance. We conducted a rigorous evaluation of the feasibility and potential to use electronic health records clinical notes and existing case review data. METHODS: Safety Learning System case review data from 1 large health system composed of 10 hospitals in the mid-Atlantic region of the United States from February 2016 to September 2021 were analyzed. The case review outcome included opportunities for improvement including diagnostic opportunities for improvement. To supplement case review data, electronic health record clinical notes were extracted and analyzed. A simple logistic regression model along with 3 forms of logistic regression models (ie, Least Absolute Shrinkage and Selection Operator, Ridge, and Elastic Net) with regularization functions was trained on this data to compare classification performances in classifying patients who experienced diagnostic errors during hospitalization. Further, statistical tests were conducted to find significant differences between female and male patients who experienced diagnostic errors. RESULTS: In total, 126 (7.4%) patients (of 1704) had been identified by case reviewers as having experienced at least 1 diagnostic error. Patients who had experienced diagnostic error were grouped by sex: 59 (7.1%) of the 830 women and 67 (7.7%) of the 874 men. Among the patients who experienced a diagnostic error, female patients were older (median 72, IQR 66-80 vs median 67, IQR 57-76; P=.02), had higher rates of being admitted through general or internal medicine (69.5% vs 47.8%; P=.01), lower rates of cardiovascular-related admitted diagnosis (11.9% vs 28.4%; P=.02), and lower rates of being admitted through neurology department (2.3% vs 13.4%; P=.04). The Ridge model achieved the highest area under the receiver operating characteristic curve (0.885), specificity (0.797), positive predictive value (PPV; 0.24), and F1-score (0.369) in classifying patients who were at higher risk of diagnostic errors among hospitalized patients. CONCLUSIONS: Our findings demonstrate that natural language processing can be a potential solution to more effectively identifying and selecting potential diagnostic error cases for review and therefore reducing the case review burden.

The effect of mindfulness-based intervention on cognitively unimpaired older adults' cognitive function and sleep quality: a systematic review and meta-analysis.

Objective: This systematic review and meta-analysis aimed to investigate the effect of mindfulness-based intervention (MBI) on cognitively unimpaired older adults' cognitive function and sleep quality.Method: Studies published in English since 2010 were considered for inclusion. Databases searched were PubMed, Embase, Web of Science, and PsycInfo. We included randomized controlled trials (RCTs) with adults over 55 with no known cognitive impairment, that recorded cognitive outcomes and/or sleep quality pre- and post-intervention, and that implemented Mindfulness-Based Stress Reduction (MBSR), or an MBI closely based on MBSR protocol.Results: Seven RCTs fit the inclusion criteria, with 276 participants in MBI groups and 287 in controls. Four studies investigated mindfulness and cognitive function, two investigated mindfulness and sleep quality, and one investigated mindfulness, cognitive function, and sleep quality. Some studies were not reported in sufficient detail to be included in meta-analyses. Results of meta-analyses showed no significant differences between MBI groups vs controls on cognitive measures of executive function, free recall, and delayed recall. Meta-analysis revealed that MBI significantly improved sleep quality compared to controls.Conclusion: Given that poor sleep quality is strongly linked to increased risk of cognitive decline, further research investigating sleep quality's role in the mindfulness-cognitive function relationship in cognitively unimpaired older adults is recommended.

Detection, Characterization, and Distribution of the First Case of Pepino Mosaic Virus in Aotearoa New Zealand.

Tomato (Solanum lycopersicum L., family Solanaceae) represents one of the most economically valuable horticultural crops worldwide. Tomato production is affected by numerous emerging plant viruses. We identified, for the first time in New Zealand (NZ), Pepino mosaic virus (PepMV) in greenhouse grown tomato crops using a combination of methods from electron microscopy and herbaceous indexing to RT-qPCR and high-throughput sequencing. Phylogenetic and genomic analysis of a near-complete PepMV genome determined that the detected strain belonged to the mild form of the CH2 lineage of the virus. Subsequently, a delimiting survey of PepMV was conducted, and PepMV was detected at four additional locations. PCR-derived sequences obtained from samples collected from different greenhouses and from herbaceous indicator plants were identical to the original sequence. Since PepMV has never been reported in NZ before, seed pathways are speculated to be the most likely source of entry into the country.

Family experiences reported by healthcare worker parents during the COVID-19 pandemic.

PURPOSE: Parents, who were working as essential frontline healthcare workers experienced unique stressors during the COVID-19 pandemic including disruption of regular routines, long lapses away from family, extreme work stress and subsequent difficulty in compartmentalizing work-related concerns when at home. The purpose of this study was to assess COVID-19 exposure and impact of frontline healthcare workers who are parents. DESIGN & METHODS: This study quantitatively assessed the COVID-19 exposure and impact and qualitatively explored perceptions of parents of children 9 to 17 years of age, who were also frontline healthcare workers. RESULTS: Participants (N = 79) using the COVID-19 Exposure and Family Impact Survey (CEFIS) reported exposure mean scores of 10.03 (SD = 2.63); and impact scores mean scores of 3.18 (SD = 0.46). Thematic analysis identified four themes, each with 2 subthemes: 1) family stressors increased (e.g., concerns about health and safety, losses of lifestyle patterns); 2) changes in children's health and well-being (e.g., isolation from family and friends, mental health problems); 3) virtual school difficulties (e.g., parent and student challenges, home school option); 4) skill building opportunities (e.g., enhanced emotional connections, increased family activities). CONCLUSION: The CHAMPS Family Health Study suggests that families of essential workers are especially vulnerable to the effect of COVID-19, as are those families of essential workers who include child/ren with special health care needs. PRACTICE IMPLICATIONS: Preparation for future emergencies requires strategies to mitigate consequences and promote well-being. These results highlight the need for supportive approaches to decrease the negative consequences of stress and to augment skills for family connection and cooperation.

Reinfection and Risk Behaviors After Treatment of Hepatitis C Virus Infection in Persons Receiving Opioid Agonist Therapy : A Cohort Study.

BACKGROUND: Hepatitis C virus (HCV) reinfection after successful treatment may reduce the benefits of cure among people who inject drugs. OBJECTIVE: To evaluate the rate of HCV reinfection for 3 years after successful treatment among people receiving opioid agonist therapy (OAT). DESIGN: A 3-year, long-term, extension study of persons enrolled in the CO-STAR (Hepatitis C Patients on Opioid Substitution Therapy Antiviral Response) study (ClinicalTrials.gov: NCT02105688). SETTING: 55 clinical trial sites in 13 countries. PATIENTS: Aged 18 years and older with chronic HCV infection with genotypes 1, 4, or 6 receiving stable OAT. INTERVENTION: No treatments were administered. MEASUREMENTS: Serum samples were assessed for HCV reinfection. Urine drug screening was performed. RESULTS: Among 296 participants who received treatment, 286 were evaluable for reinfection and 199 were enrolled in the long-term extension study. The rate of HCV reinfection was 1.7 [95% CI, 0.8 to 3.0] per 100 person-years; 604 person-years of follow-up). A higher rate of reinfection was seen among people with recent injecting drug use (1.9 [95% CI, 0.5 to 4.8] per 100 person-years; 212 person-years). Ongoing drug use and injecting drug use were reported by 59% and 21% of participants, respectively, at the 6-month follow-up visit and remained stable during 3 years of follow-up. LIMITATIONS: Participants were required to be 80% adherent to OAT at baseline and may represent a population with higher stability and lower risk for HCV reinfection. Rate of reinfection may be underestimated because all participants did not continue in the long-term extension study; whether participants who discontinued were at higher risk for reinfection is unknown. CONCLUSION: Reinfection with HCV was low but was highest in the first 24 weeks after treatment completion and among people with ongoing injecting drug use and needle-syringe sharing.

A test of differential susceptibility in behavior trajectories of preterm infants from preschool to adulthood.

Preterm birth predisposes children to internalizing and externalizing behaviors that may persist into adolescence resulting in adult mental health conditions. Social and caregiving contexts, particularly for vulnerable infants born preterm, influence long-term outcomes, but mechanisms are not clearly understood. Healthcare teams caring for those born preterm face difficulty predicting who will be most affected by risk, who will most benefit, and the optimal timing of intervention. Differential susceptibility theory offers an alternative to the traditional risk-only assessments and theories by positing that individuals may be more, or less, susceptible to environmental influences. A sample of preterm- and term-born infants were followed from birth to 23 years of age. Mixed model repeated measures analyses of internalizing and externalizing behaviors were utilized for the comparison groups (N = 214; observations = 1070). Environmental contexts were indexed as proximal protection (low, moderate, high) and medical risk (low, moderate, high). Personal characteristic covariates of sex, race, socioeconomic status, and cognition were modeled. Internalizing behavior trajectories varied significantly over time. Early proximal protective environments conferred a sustained positive influence on behaviors. There is partial support for differential susceptibility theory suggesting that prematurity, as a malleability characteristic enables absorption of both the positive and negative influences of the environment, with greater intensity that those without malleability. The current analyses suggest lasting effects of the preschool age proximal environment on internalizing and externalizing behaviors in young adulthood for those born preterm. Understanding these nuances may aid healthcare professionals in the promotion and timing of interventions to support the child and family. The current manuscript reflects ongoing analyses of longitudinal data. No patient or public contribution to the analyses were required for testing the differential susceptibility theory. The authors would solicit patient or public contribution when implementing practice or policy changes based on the results.

Risk factors, prevention and treatment of hypoglycaemia after hyperkalaemia in adult patients using intravenous insulin: An integrative review.

AIM: An integrative review was conducted to synthesize published evidence on the prevention and treatment of hypoglycaemia and patient risk factors, in adult patients treated for hyperkalaemia with intravenous insulin and dextrose. METHODS: This review followed the framework by Whittemore and Knafl. Papers included were limited to English language studies involving participants who were aged 18 years and above and admitted in the inpatient acute care and emergency departments. The literature search was performed using five electronic databases (CINAHL, Embase, PubMed, Proquest and Cochrane). RESULTS: A total of 22 studies were included. Two main themes were derived-patient risk factors and prevention-intervention strategies. Five main patient risk factors were lower pretreatment blood glucose (<7 mmol/L), lower weight, renal insufficiencies, older age and nondiabetic. The four subthemes in the prevention-intervention strategies included (i) methods of administration and dosing of intravenous insulin and dextrose, (ii) frequency of blood glucose monitoring, (iii) education to healthcare professionals and (iv) rescue agents. CONCLUSIONS: Standardized computerized order sets and integrated decision tool that can advise appropriate prescription of a higher volume of dextrose or lower insulin dose according to patient risk factors, regular monitoring and reinforced education may prevent and mitigate the risk of hypoglycaemia.

Use and Effectiveness of Virtual Simulations in Nursing Student Education: An Umbrella Review.

Computer-based virtual simulation in nursing is a rapidly developing field. A summary of current research could benefit nursing faculty who are incorporating this pedagogy into online teaching due to social distancing requirements. This umbrella review aimed to explore the use and effectiveness of virtual simulations in prelicensure nursing education. Our umbrella review approach was informed by The Johanna Briggs Institute guidelines. The 18 included reviews captured the experiences of over 7600 nursing students who engaged with five different virtual (screen-based) simulation modalities. Results indicated that virtual simulations can be effective in developing nursing students' knowledge and psychomotor and psychosocial skills, for example, in medication administration and communication. There was no study that showed a conclusive benefit of virtual simulations for developing clinical reasoning. Students enjoyed virtual simulations, claiming they were accessible, fun, and engaging ways to learn. Many benefits of virtual simulations and some technological challenges were identified in a mapped model. In the future, more rigorous and experimental studies are needed to confirm effects on learning outcomes. Nursing curriculum designers need to define the place and purposes of the pedagogy to ensure that knowledge and skills learned during virtual simulations can be applied to real-world, patient-centered care.

Diagnostic Reasoning Competency and Accuracy by Nurse Practitioner Students Following the Use of Structured Reflection in Simulation: A Mixed-Methods Experiment.

AIM: The aim of this study was to examine the effect of structured reflection used during a simulated patient's diagnostic workup on diagnostic reasoning competency and accuracy and explore participants' cognitive bias experience and perceived utility of structured reflection. BACKGROUND: Reasoning flaws may lead to diagnostic errors. Medical learners who used structured reflection demonstrated improved diagnosis accuracy. METHOD: Embedded mixed-methods experiment examined diagnostic reasoning competency and accuracy of nurse practitioner students who did and did not use structured reflection. Cognitive bias experience and perceptions of structured reflection's utility were explored. RESULTS: Diagnostic Reasoning Assessment mean competency scores and categories were not changed. Accuracy trended toward improvement with structured reflection. The theme, diagnostic verification, prompted diagnosis change by both structured reflection users and control participants. CONCLUSION: Despite no changes in quantitative outcomes, explicit users of structured reflection believed that this strategy is helpful to their reasoning, and control participants used the strategy's components with the same noted benefits.

The glucosyltransferase activity of C. difficile Toxin B is required for disease pathogenesis.

Enzymatic inactivation of Rho-family GTPases by the glucosyltransferase domain of Clostridioides difficile Toxin B (TcdB) gives rise to various pathogenic effects in cells that are classically thought to be responsible for the disease symptoms associated with C. difficile infection (CDI). Recent in vitro studies have shown that TcdB can, under certain circumstances, induce cellular toxicities that are independent of glucosyltransferase (GT) activity, calling into question the precise role of GT activity. Here, to establish the importance of GT activity in CDI disease pathogenesis, we generated the first described mutant strain of C. difficile producing glucosyltransferase-defective (GT-defective) toxin. Using allelic exchange (AE) technology, we first deleted tcdA in C. difficile 630Δerm and subsequently introduced a deactivating D270N substitution in the GT domain of TcdB. To examine the role of GT activity in vivo, we tested each strain in two different animal models of CDI pathogenesis. In the non-lethal murine model of infection, the GT-defective mutant induced minimal pathology in host tissues as compared to the profound caecal inflammation seen in the wild-type and 630ΔermΔtcdA (ΔtcdA) strains. In the more sensitive hamster model of CDI, whereas hamsters in the wild-type or ΔtcdA groups succumbed to fulminant infection within 4 days, all hamsters infected with the GT-defective mutant survived the 10-day infection period without primary symptoms of CDI or evidence of caecal inflammation. These data demonstrate that GT activity is indispensable for disease pathogenesis and reaffirm its central role in disease and its importance as a therapeutic target for small-molecule inhibition.

In-Home COVID-19 Testing for Children With Medical Complexity: Feasibility and Association With School Attendance and Safety Perceptions.

The REstarting Safe Education and Testing program for children with medical complexity was implemented in May 2021 at the University of Wisconsin to evaluate the feasibility of in-home rapid antigen COVID-19 testing among neurocognitively affected children. Parents or guardians administered BinaxNOW rapid antigen self-tests twice weekly for three months and changed to symptom and exposure testing or continued surveillance. In-home testing was feasible: nearly all (92.5%) expected tests were conducted. Symptomatic testing identified seven of nine COVID-19 cases. School safety perceptions were higher among those opting for symptom testing. Clinical Trials.gov identifier: NCT04895085. (Am J Public Health. 2022;112(S9):S878-S882. https://doi.org/10.2105/AJPH.2022.306971).

Caregiver perceptions of in-home COVID-19 testing for children with medical complexity: a qualitative study.

BACKGROUND: In-home direct antigen rapid testing (DART) plays a major role in COVID-19 mitigation and policy. However, perceptions of DART within high-risk, intellectually impaired child populations are unknown. This lack of research could negatively influence DART uptake and utility among those who stand to benefit most from DART. The purpose of this study was to describe caregivers' perceptions of an in-home COVID-19 DART regimen in children with medical complexity, including the benefits and limitations of DART use. METHODS: This qualitative study was a subproject of the NIH Rapid Acceleration of Diagnostics Underserved Populations research program at the University of Wisconsin. We combined survey data and the thematic analysis of semi-structured interview data to understand caregivers' perceptions of in-home COVID-19 testing and motivators to perform testing. Caregivers of children with medical complexity were recruited from the Pediatric Complex Care Program at the University of Wisconsin (PCCP). Data were collected between May and August 2021. RESULTS: Among n = 20 caregivers, 16/20 (80%) of their children had neurologic conditions and 12/20 (60%) used home oxygen. Survey data revealed that the largest caregiver motivators to test their child were to get early treatment if positive (18/20 [90%] of respondents agreed) and to let the child's school know if the child was safe to attend (17/20 [85%] agreed). Demotivators to testing included that the child could still get COVID-19 later (7/20 [35%] agreed), and the need for officials to reach out to close contacts (6/20 [30%] agreed). From interview data, four overarching themes described perceptions of in-home COVID-19 testing: Caregivers perceived DART on a spectrum of 1) benign to traumatic and 2) simple to complex. Caregivers varied in the 3) extent to which DART contributed to their peace of mind and 4) implications of test results for their child. CONCLUSIONS: Although participants often described DART as easy to administer and contributing to peace of mind, they also faced critical challenges and limitations using DART. Future research should investigate how to minimize the complexity of DART within high-risk populations, while leveraging DART to facilitate safe school attendance for children with medical complexity and reduce caregiver burden.

A Protocol to Assess Adult Outcomes at 30 Years Following Preterm Birth.

BACKGROUND: Among the most intense adversity experiences for infants is premature birth. Early birth marks the beginning of a life course that broadly affects families, healthcare, education, social systems, and the survivors themselves. For many, the transition to adulthood is challenging and often hampered by cognitive, physical and mental health, and motor and independence difficulties. OBJECTIVES: The aim of this study was to share a comprehensive protocol of a 10th follow-up study of premature infants in their 30s. The protocol accounts for stress during the neonatal period, the cumulative context (risk and protection) of development, biological and epigenetic mechanisms, and individual resilience. METHODS: The prospective, five-group longitudinal design includes 215 term-born and preterm-born individuals with various neonatal morbidities at ages 30-35 years. Adult outcomes include health, adaptive, executive function, work, and social competence. Novel measures are four system indicators of allostatic load (AL) and epigenetics. Contextual measures include socioeconomic risk and individual resilience. All measures were selected based on coherence with constructs of the scientific aims, strong psychometrics, continuity for repeated measures, and minimal subject burden. Objective assessments include body composition imaging, exercise testing, blood and saliva collection, and actigraphy. The two-phase protocol takes approximately 8 hours. DISCUSSION: After an 11-month COVID-19 pause, participant response has been strong. As of May 2022, 75 participants have completed the full protocol, and 99 have consented to participate. When socioeconomic risk is controlled, we hypothesize that life course trajectories in physical and psychological health, adaptive function, and executive function will differ between term and preterm neonatal morbidity groups. AL will vary across groups and contribute to outcomes. We expect proximal protection and resilience to mediate the cumulative medical and socioeconomic risk and AL. Epigenome-wide DNA methylation, with estimates of age acceleration, will be examined across groups and explored in longitudinal associations with medical risk, socioeconomic status, and protection. To our knowledge, this is the only U.S. study of premature infants aged 30-35 years. With millions of preterm-born individuals reaching adulthood, the protocol incorporates molecular and genetic biomarkers in a life course developmental examination to inform the timing and content of interventions.

Association Between Neighborhood Disadvantage and Pediatric Readmissions.

OBJECTIVE: Although individual-level social determinants of health (SDH) are known to influence 30-day readmission risk, contextual-level associations with readmission are poorly understood among children. This study explores associations between neighborhood disadvantage measured by Area Deprivation Index (ADI) and pediatric 30-day readmissions. METHODS: This retrospective cohort study included discharges of patients aged < 20 years from Maryland's 2013-2016 all-payer dataset. The ADI, which quantifies 17 indicators of neighborhood socioeconomic disadvantage within census block groups, is used as a proxy for contextual-level SDH. Readmissions were identified with the 30-day Pediatric All-Condition Readmissions measure. Associations between ADI and readmission were identified with generalized estimating equations adjusted for patient demographics and clinical severity (Chronic Condition Indicator [CCI], Pediatric Medical Complexity Algorithm [PMCA], Index Hospital All Patients Refined Diagnosis Related Groups [APR-DRG]), and hospital discharge volume. RESULTS: Discharges (n = 138,998) were mostly female (52.7%), publicly insured (55.1%), urban-dwelling (93.0%), with low clinical severity levels (0-1 CCIs [82.3%], minor APR-DRG severity [48.4%]). Overall readmission rate was 4.0%. Compared to the least disadvantaged ADI quartile, readmissions for the most disadvantaged quartile were significantly more likely (aOR 1.19, 95% CI 1.09-1.30). After adjustment, readmissions were associated with public insurance and indicators of medical complexity (higher number of CCIs, complex-chronic disease PMCA, and APR-DRG severity). CONCLUSION: In this all-payer, statewide sample, living in the most socioeconomically disadvantaged neighborhoods independently predicted pediatric readmission. While the relative magnitude of neighborhood disadvantage was modest compared to medical complexity, disadvantage is modifiable and thus represents an important consideration for prevention and risk stratification efforts.

Training undergraduate students for rapid on-site evaluation of fine needle aspiration cytology samples using a simulation-based education activity.

INTRODUCTION: Demand for rapid on-site evaluation (ROSE) of fine needle aspiration (FNA) cytology is rising and the role is increasingly being performed by non-medical cytologists. Undergraduate training for cytologists has traditionally focused on laboratory-based procedural activities and their theoretical underpinning, with minimal attention given to communication and other skills required to operate in an interprofessional setting. We evaluated the effectiveness and student reaction to a simulation-based education (SBE) exercise in ROSE designed to fill this void. METHODS: We designed and evaluated an SBE exercise based on FNA ROSE across two tertiary institutions with 79 students. The exercise accurately reproduced the demands on cytologists operating as part of a multi-disciplinary team in a time- pressured environment. FINDINGS: Pre- and post-simulation questionnaires indicated an improvement in technical knowledge related to the procedure. Students' perception of their competence and confidence in their role also improved significantly post simulation. Students uniformly found the exercise engaging and a valuable addition to their curriculum. DISCUSSION: The simulation successfully provided a pseudo-clinical environment that highlighted the realities of practising technical and diagnostic tasks under time pressure and interacting with other health professionals to provide an optimal patient outcome. The exercise is a useful supplement to on-the-job training for ROSE.

Trajectories of socio-emotional functioning in early-stage dementia: implications for the individual with dementia and their family carer.

BACKGROUND AND OBJECTIVES: Changes in socio-emotional functioning in people living with dementia (PLWD) are common; however, little is known about the broader effects these may have on wellbeing. This study examined socio-emotional functioning over time and associations with the wellbeing of PLWD and their family carers. METHOD: One hundred and one individuals with a diagnosis of dementia and their respective carers completed the Social Emotional Questionnaire (assessing emotion recognition, empathy, social relationships and social behaviour) alongside measures of dementia severity, cognition, mood, stress, and relationship quality. Sixty-six dyads were reassessed on the same measures at 12 months post-baseline, and 51 dyads again at 20 months post-baseline. RESULTS: When rated by the PLWD, there was no change in socio-emotional functioning over time; however, carers reported a significant decline over time. For both carers and the PLWD, poorer wellbeing measures were indicative of worse socio-emotional functioning at Time 1, though only dementia type, quality of life and relationship quality impacted upon the trajectory of socio-emotional decline over time. CONCLUSIONS: Changes in social and emotional functioning are evident early in the course of dementia and worsen within 20 months. Both carer characteristics and those of the PWLD affected reporting of social and emotional functioning. These data are useful for guiding the provision of appropriate education and care.

Understanding Nurse Characteristics that Influence Assessment and Intention to Treat Pain in Postoperative Patients: An Integrative Literature Review.

OBJECTIVES: An understanding of nurse characteristics that influence pain management, which are potentially amenable to change, can help to refine and improve nurse education and practice, resulting in better patient outcomes. The purpose of this review was to identify nurse characteristics that influence their assessment of and intention to treat postoperative pain. DESIGN: Integrative literature review. DATA SOURCES: A systematic search of electronic databases (CINAHL, Scopus, PsycINFO, Medline, and Embase), using these constructs "pain assessment", "pain management", "postoperative pain", "nurses", "cultural beliefs" and "nurses' perceptions" was conducted for the period 2000 to October 2020. REVIEW/ANALYSIS METHODS: Following a systematic screening process, the included articles were analyzed and synthesized to identify themes and subthemes. RESULTS: A total of 40 articles were included with three main themes identified: nurse knowledge; nurse sociocultural factors, personal beliefs and attitudes, and other characteristics; and believing or doubting the patient. There was evidence that targeted education interventions can improve nurse knowledge and nurses' clinical practice in relation to pain management. What was less clear was which nurse attitudes and biases influenced their pain management practice or how these could be changed. CONCLUSIONS: More studies are needed to investigate the influence of cultural characteristics on pain assessment and management. There is a need for further quantitative studies that explore the relationship between nurse characteristics and their pain management practice. Intervention studies using innovative educational approaches that change attitudes and biases, and improve practice are needed.

First report of Grapevine Algerian latent virus in carnation in New Zealand.

Carnation (Dianthus caryophyllus) is a popular ornamental plant widely used as a cut flower and in landscaping. In New Zealand, several viruses are known to infect plants of the genus Dianthus: arabis mosaic virus, carnation etched ring virus (CERV), carnation latent virus, carnation mottle virus, carnation necrotic fleck virus, carnation ringspot virus, carnation vein mottle virus and cucumber mosaic virus (Veerakone et al. 2015). In October 2020, a carnation sample with leaf chlorotic spots and distortion from a home garden in Auckland, New Zealand was submitted to the Plant Health and Environment Laboratory (PHEL) for virus testing. Leaf tissue of the sample was mechanically inoculated onto a range of herbaceous species using the method described in Tang et al. (2013). Chenopodium amaranticolor and C. quinoa plants developed local necrotic pinpoint spots while Nicotiana benthamiana, N. clevelandii, and N. occidentalis plants exhibited systemic leaf mosaic symptoms 7 days post-inoculation. The carnation plant and all five symptomatic indicator species tested positive for tombusviruses using an in-house designed generic RT-qPCR (available on request). Direct sequencing of the ~140 bp PCR product revealed the presence of grapevine Algerian latent virus (GALV). To further characterise the detected sequence, forward (5'-GTAGCGATGTATTGGGATAAGGA-3') and reverse (5'-TGCCGACACCCCGAAAGGT-3') primers were designed based on an alignment of the conserved region in the coat protein (CP) of 19 GALV isolates deposited in GenBank. Products of the expected size of 406 bp were amplified from all infected plants and their sequences found to be identical (GenBank accession No. OM891837). BLAST searches showed that the CP region of the sequence shared 97.0% (nucleotide) and 97.8% (amino acid) identity to the type isolate of GALV (GenBank accession no. NC_011535). GALV was first reported in Italy from a symptomless Algerian grapevine (Vitis vinifera) (Gallitelli et al., 1989), and is the only report of GALV in Vitis in the world. Since then, GALV has been reported in Germany, the Netherlands and Japan in several ornamental plant species including Alstroemeria sp. (Tomitaka et al., 2016), Gypsophila paniculata, Limonium sinuatum (Koenig et al., 2004, Fujinaga et al., 2009) and Solanum mammosum (Ohki et al., 2006). These infected ornamental host plants were reported to show various types of foliar symptoms, including chlorotic leaf spots. The GALV-infected carnation plant in this study was tested by PCR for all viruses that are known to infect D. caryophyllus in New Zealand, and CERV was identified. It is therefore unclear if the observed symptoms were induced by either GALV or CERV, or if they were the results of a synergistic interaction between GALV and CERV. Samples from a further 11 plants, comprised of nine symptomatic Dianthus spp. and two asymptomatic Alstroemeria spp. were collected from the same address and tested individually using the GALV-specific RT-PCR. GALV (along with CERV) was detected from all Dianthus plants while the Alstroemeria samples were negative. To our knowledge, this is the first report of GALV in New Zealand, and the first report in the host Dianthus in the world. Given the GALV-infected carnation plants were purchased from a local garden centre between 2007-2020, and plants from this garden centre have been widely distributed over this period of time to various customers, the virus is very likely to have spread throughout the country.
