Abstract
OBJECTIVES To investigate the impact of including the response option of 'Possibly' in the Distress question on the Matthey Generic Mood Questionnaire (MGMQ) during antenatal emotional health screening in English-speaking women. BACKGROUND Some distress screening questions only allow respondents to choose between 'Yes' or 'No' to the presence of distress. The MGMQ, however, allows respondents to chose between 'Yes', 'Possibly', or 'No', which may be preferable if a participant is reluctant to state she definitely feels distressed. METHOD In Study 1, women undergoing routine antenatal psychosocial screening were allocated to either completing the MGMQ Distress question with the usual three-option response format of 'Yes, Possibly, No' (N = 960), or just a 'Yes, No' response format (N = 771). The proportion of responses were compared in each group, as were the proportion then screening positive on the MGMQ's Bother question. In Study 2, women (N = 113) attending routine antenatal clinic appointments were asked about their preference between these response formats. RESULTS Including 'Possibly' resulted in only a slight increase in the proportion giving a positive response to the Distress question, and then also screening positive on the Bother question. In Study 2, a substantial majority of women (80%) preferred having 'Possibly' in the response options. CONCLUSION While the impact of including 'Possibly' is small, it allows for more women to communicate how they are feeling on the full MGMQ. Given the large majority of women preferring having 'Possibly' included, we believe that the Distress Question is enhanced by having this as a response option.

Abstract
AIM To explore the importance of health workforce training, particularly in newly regulated healthcare practices such as assisted dying (AD). This study aims to analyse the socio-demographic factors associated with health professionals' completion of the e-learning module and attendance at the two webinars provided by the New Zealand Ministry of Health - Manatū Hauora (MH) and whether completion of the e-learning module and webinars supported health professionals' understanding of the End of Life Choices Act 2019. METHOD Secondary analysis of the MH workforce surveys conducted in July 2021. RESULTS The study findings indicate that health professionals who are older, of Pākehā/European ethnicity and work in hospice settings are more likely to complete the e-learning module, while females are more likely to attend webinars. CONCLUSION Despite low completion and attendance rates, the study highlights the positive association between training and health professionals' overall understanding of the Act. These results emphasise the need for enhancing training programmes to increase health professionals' knowledge and competence with AD. Furthermore, the research proposes focussing on healthcare practitioners in the early stages of their careers and not directly engaged in offering AD services, as well as Māori and Pasifika health practitioners.

Abstract
BACKGROUND In November 2021, assisted dying (AD) became lawful in Aotearoa New Zealand. A terminally ill person may now request, and receive, pharmacological assistance (self-administered or provided by a medical practitioner/nurse practitioner) to end their life, subject to specific legal criteria and processes. Exploring the experiences of health providers in the initial stage of the implementation of the End of Life Choice Act 2019 is vital to inform the ongoing development of safe and effective AD practice, policy and law. AIM To explore the early experiences of health care providers (HCPs) who do and do not provide AD services seven months after legalisation of AD to provide the first empirical account of how the AD service is operating in New Zealand's distinctive healthcare environment and cultural context. DESIGN Qualitative exploratory design using semi-structured individual and focus group interviewing with a range of HCPs. RESULTS Twenty-six HCPs participated in the study. Through a process of thematic analysis four key themes were identified: (1) Difference in organisational response to AD; (2) challenges in applying the law; (3) experiences at the coal face; and (4) functionality of the AD system. CONCLUSION A range of barriers and enablers to successful implementation of AD were described. Adoption of open and transparent organisational policies, ongoing education of the workforce, and measures to reduce stigma associated with AD are necessary to facilitate high quality AD service provision. Future research into the factors that influence responses to, and experience of AD; the impact of institutional objection; and the extent to which HCP perspectives evolve over time would be beneficial. In addition, further research into the integration of AD within Māori health organisations is required.

Abstract
AIM To determine socio-demographic factors associated with health professionals' understanding of the End of Life Choice Act (the Act), support for assisted dying (AD), and willingness to provide AD in New Zealand. METHOD Secondary analysis of two Manatū Hauora - Ministry of Health workforce surveys conducted in February and July 2021. RESULTS Our analysis showed (1) older health professionals (age>55) had a better overall understanding of the Act than their young colleagues (age35), (2) female health professionals were less likely to support and be willing to provide AD, (3) Asian health professionals were less likely to support AD compared to their Pākehā/European counterparts, (4) nurses were more likely to support AD and be willing to provide AD when compared to medical practitioners, and (5) pharmacists were more willing to provide AD when compared to medical practitioners. CONCLUSION Several socio-demographic factors, including age, gender, ethnicity, and professional background, are significantly associated with health professionals' support and willingness to provide AD, with likely consequences for the AD workforce availability and service delivery in New Zealand. Future review of the Act could consider enhancing the roles of those professional groups with higher support and willingness to assist in providing AD services in caring for people requesting AD.

Abstract
INTRODUCTION As chest imaging is a tool for detecting coronavirus disease 2019 (COVID-19), diagnostic radiographers are a key component of the frontline workforce. Due to its unforeseen nature, COVID-19 has challenged radiographers' preparedness in combating its effects. Despite its importance, literature specifically investigating radiographers' readiness is limited. However, the documented experiences are prognostic of pandemic preparedness. Hence, this study aimed to map this literature by addressing the question: 'what does the existing literature reveal about the pandemic preparedness of diagnostic radiographers during COVID-19?'. METHODS Using Arksey and O'Malley's framework, this scoping review searched for empirical studies in MEDLINE, Embase, Scopus, and CINAHL. Consequently, 970 studies were yielded and underwent processes of deduplication, title and abstract screening, full-text screening, and backward citation searching. Forty-four articles were deemed eligible for data extraction and analysis. RESULTS Four themes that reflected pandemic preparedness were extrapolated: infection control and prevention, knowledge and education, clinical workflow, and mental health. Notably, the findings highlighted pronounced trends in adaptation of infection protocols, adequate infection knowledge, and pandemic-related fears. However, inconsistencies in the provision of personal protective equipment, training, and psychological support were revealed. CONCLUSION Literature suggests that radiographers are equipped with infection knowledge, but the changing work arrangements and varied availability of training and protective equipment weakens their preparedness. The disparate access to resources facilitated uncertainty, affecting radiographers' mental health. IMPLICATIONS FOR PRACTICE By reiterating the current strengths and weaknesses in pandemic preparedness, the findings can guide clinical practice and future research to correct inadequacies in infrastructure, education, and mental health support for radiographers in the current and future disease outbreaks.

Abstract
BACKGROUND New Zealand recently introduced law permitting terminally ill people to request and receive assisted dying (AD) in specified circumstances. Given the nature and complexity of this new health service, research is vital to determine how AD is operating in practice. OBJECTIVE To identify research priorities regarding the implementation and delivery of AD in New Zealand. METHODS Using an adapted research prioritisation methodology, the researchers identified 15 potential AD research topics. A mixed-methods survey of health professionals was undertaken where respondents were asked to rate the 15 topics according to the relative importance for research to be conducted on each issue. Respondents could also suggest additional research areas, and were invited to participate in a follow-up interview. RESULTS One hundred and nineteen respondents completed the survey. 31% had some experience with AD. The highest rated research topic was the 'effectiveness of safeguards in the Act to protect people'; the lowest rated topic was research into the 'experiences of non-provider (e.g., administrative, cleaning) staff where assisted dying is being provided'. Respondents suggested 49 other research topics. Twenty-six interviews were conducted. Thematic analysis of interview data and open-ended survey questions was undertaken. Six research themes were identified: general factors related to the wider health system; the experiences of health care providers at the bedside; medico-legal issues; the impact of AD; experiences on the day of dying; and the overall effectiveness of the AD system. Key issues for stakeholders included safety of the AD service; ensuring access to AD; achieving equity for 'structurally disadvantaged' groups; and ensuring the well-being of patients, families/whānau, providers and non-providers. CONCLUSIONS Based on early experiences of the implementation of the AD service, health professionals provide important insights into what research should be prioritised post-legalisation of AD. These findings can be used to shape the research agenda so that research may inform law, policy and best practice.

Abstract
Sagnac interferometry is advantageous in measuring time-reversal-symmetry breaking effects in ferromagnetic and antiferromagnetic materials as it suppresses time-reversal symmetric birefringent effects that are ubiquitous and often overwhelming in optical detection systems. When its sensitivity is limited only by the amplifier noise in the photo-detector, one needs to optimize the optical power that returns to the detector. We demonstrate an experimental scheme that maximizes the returning optical power in a Sagnac interferometry when detecting the magneto-optic effect in ultrathin films. In this scheme, the optical beam bearing the Faraday effect on a thin film is reflected at a second surface coated with a highly reflective gold film. The gold film increases the returned optical power by a factor of 4-5. For a normal-incidence Sagnac interferometer, this scheme yields an increase in the signal-to-noise ratio by the same factor. For an oblique-incidence Sagnac interferometer, this scheme should yield an increase in the signal-to-noise ratio by a factor of 20-25. For illustration, this scheme is used to measure magnetization curves and Kerr rotation images of 4.5-unit-cell thick SrRuO3(001) grown on SrTiO3(001).

Abstract
BackgroundRituximab is widely used to treat rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) but clinical response varies. Efficacy is determined by the efficiency of depletion, which may depend on a variety of Fc gamma receptor (FcγR)-dependent mechanisms. Previous research was limited by complexity of the FCGR locus, not integrating copy number variation with functional SNP, and small sample size.ObjectivesThe study objectives were to assess the effect of the full range of FcγRs variants on depletion, clinical response and functional effect on NK-cell-mediated killing in two rheumatic diseases with a view to personalised B-cell depleting therapies.MethodsA prospective longitudinal cohort study was conducted in 873 patients [RA=611; SLE=262] from four cohorts (BSRBR-RA and BILAG-BR registries, Leeds RA and Leeds SLE Biologics). For RA, the outcome measures were 3C-DAS28CRP and 2C-DAS28CRP at 6 (+/-3) months post-rituximab (adjusted for baseline DAS28). For SLE, major clinical response (MCR) was defined as improvement of active BILAG-2004 domains to grade C/better at 6 months. B-cell depletion was evaluated by highly-sensitive flow cytometry. Qualitative and quantitative polymorphisms for five major FcγRs were measured using a commercial multiplex ligation-dependent probe amplification. Median NK cell FcγRIIIa expression (CD3-CD56+CD16+) and NK-cell degranulation (CD107a) in the presence of rituximab-coated Daudi/Raji B-cell lines were assessed using flow cytometry.ResultsIn RA, for FCGR3A, carriage of V allele (coefficient -0.25 (SE 0.11); p=0.02) and increased copies of V allele (-0.20 (0.09); p=0.02) were associated with greater 2C-DAS28 response. Irrespective of FCGR3A genotype, increased gene copies were associated with a better response. In SLE, 177/262 (67.6%) achieved BILAG response [MCR=34.4%; Partial=33.2%]. MCR was associated with increased copies of FCGR3A-158V allele, OR 1.64 (95% CI 1.12-2.41) and FCGR2C-ORF allele 1.93 (1.09-3.40). Of patients with B-cells data in the combined cohort, 236/413 (57%) achieved complete depletion post-rituximab. Only homozygosity for FCGR3A-158V and increased FCGR3A-158V copy number were associated with increased odds of complete depletion. Patients with complete depletion had higher NK cell FcγRIIIa expression at rituximab initiation than those with incomplete depletion (p=0.04) and this higher expression was associated with improved EULAR response in RA. Moreover, for FCGR3A, degranulation activity was increased in V allele carriers vs FF genotype in the combined cohort; p=0.02.ConclusionFcγRIIIa is the major low affinity FcγR and increased copies of the FCGR3A-158V allele, encoding the allotype with a higher affinity for IgG1, was associated with clinical and biological responses to rituximab in two autoimmune diseases. This was supported by functional data on NK cell-mediated cytotoxicity. In SLE, increased copies of the FCGR2C-ORF allele was also associated with improved response. Our findings indicate that enhancing FcγR-effector functions could improve the next generation of CD20-depleting therapies and genotyping could stratify patients for optimal treatment protocols.ReferencesNoneAcknowledgementsThis research was funded/supported by the joint funding from the Medical Research Council (MRC) and Versus Arthritis of MATURA (grant codes 36661 and MR/K015346/1).

Background
The COVID-19 pandemic resulted in the abrupt suspension of centre-based cardiac rehabilitation (CR). Multidisciplinary virtual CR (VCR) with the use of digital, telephone, and video communication was implemented for continued care access. Exercise therapy was delivered through synchronous video-supervised sessions, pre-recorded sessions, and self-directed physical activity.
Purpose
To describe patient characteristics, completion rates, and safety outcomes in a real-world VCR population.
Methods
Prospective observational study of a tertiary academic CR program. VCR was implemented at pandemic onset (March 2020). Patients who were enrolled in, and either completed or dropped out, during the study period were included. Completers were defined as completing 6 months of virtual enrolment and an exit assessment. Risk was defined by the AACPVR 2020 risk categorization. Adverse cardiovascular events were defined as a patient-initiated event requiring medical assessment and stratified as exercise or non-exercise related. Continuous variables are presented as means and SD or medians and IQR. Student’s t-test was used for between group comparisons. Categorical variables are presented as n (%) and compared using the χ2 test or Fischer’s exact test. A p-value <0.05 was considered significant.
Results
Between March 13th, 2020, and August 31st, 2021, 222 [mean age 61.8 years (SD, 12.6) 77% male], were enrolled and discharged from the VCR program (Table 1). There were 160 completers and 62 non-completers (completion rate 72%). Among the non-completers 26 attended the MD intake assessment only. The remaining 36 completed a median of 85 days (IQR 25-197). This cohort included 21 (9%) high-risk and 35 (16%) moderate risk patients. Those at moderate risk were more likely to be non-completers and those at low risk were more likely to be completers (Table 1). Two exercise and 17 non-exercise adverse events were observed (median clinical surveillance 217 days [IQR 205-240]) (Table 2). Exercise related adverse events included neurally mediated syncope during a synchronous video exercise session in a low risk patient. This was responded to as per centre developed virtual safety protocols. A second syncope related to heart block occurred in a moderate risk patient during independent physical activity and required permanent pacemaker insertion. Both patients completed the program. Three non-exercise adverse cardiac events resulted in cessation of participation included one death and two heart failure hospitalizations (Table 2). One stroke and 13 emergency department visits for cardiac symptoms occurred in completers.
Conclusion
Real world VCR is feasible, including in those at moderate to high risk. Modest completion rates and a low exercise related adverse event rate were observed. Synchronous video exercise sessions with video monitoring and safety protocols may improve response to adverse exercise related events.

Abstract
BACKGROUND Accurate diagnostic tools to identify patients at risk of cancer therapy-related cardiac dysfunction (CTRCD) are critical. For patients undergoing cardiotoxic cancer therapy, ejection fraction assessment using radionuclide ventriculography (RNVG) is commonly used for serial assessment of left ventricular (LV) function. METHODS In this retrospective study, approximate entropy (ApEn), synchrony, entropy, and standard deviation from the phase histogram (phase SD) were investigated as potential early markers of LV dysfunction to predict CTRCD. These phase parameters were calculated from the baseline RNVG phase image for 177 breast cancer patients before commencing cardiotoxic therapy. RESULTS Of the 177 patients, 11 had a decline in left ventricular ejection fraction (LVEF) of over 10% to an LVEF below 50% after treatment had commenced. This patient group had a significantly higher ApEn at baseline to those who maintained a normal LVEF throughout treatment. Of the parameters investigated, ApEn was superior for predicting the risk of CTRCD. Combining ApEn with the baseline LVEF further improved the discrimination between the groups. CONCLUSIONS The results suggest that RNVG phase analysis using approximate entropy may aid in the detection of sub-clinical LV contraction abnormalities, not detectable by baseline LVEF measurement, predicting a subsequent decline in LVEF.

Abstract
We propose a novel integrated framework that jointly models complementary information from resting-state functional MRI (rs-fMRI) connectivity and diffusion tensor imaging (DTI) tractography to extract biomarkers of brain connectivity predictive of behavior. Our framework couples a generative model of the connectomics data with a deep network that predicts behavioral scores. The generative component is a structurally-regularized Dynamic Dictionary Learning (sr-DDL) model that decomposes the dynamic rs-fMRI correlation matrices into a collection of shared basis networks and time varying subject-specific loadings. We use the DTI tractography to regularize this matrix factorization and learn anatomically informed functional connectivity profiles. The deep component of our framework is an LSTM-ANN block, which uses the temporal evolution of the subject-specific sr-DDL loadings to predict multidimensional clinical characterizations. Our joint optimization strategy collectively estimates the basis networks, the subject-specific time-varying loadings, and the neural network weights. We validate our framework on a dataset of neurotypical individuals from the Human Connectome Project (HCP) database to map to cognition and on a separate multi-score prediction task on individuals diagnosed with Autism Spectrum Disorder (ASD) in a five-fold cross validation setting. Our hybrid model outperforms several state-of-the-art approaches at clinical outcome prediction and learns interpretable multimodal neural signatures of brain organization.

Abstract
Abstract
Coronavirus disease 2019 has affected millions of people worldwide. Its clinical spectrum ranges from completely asymptomatic to significant respiratory and non-respiratory symptoms leading to critical illness, including death. We aimed to study the effects of body mass index (BMI) on cardiovascular and other critical illness outcomes in these patients in the USA. We conducted a systematic search of three databases for the period of November 2019 to August 2020 and selected 37 studies for analysis. One study showed a non-significant difference in cardiac injury among BMI groups, but there is a paucity of data on cardiovascular outcomes among different BMI groups; hence, meta-analysis was not done for cardiovascular outcomes. Both high BMI and cardiac injury are independent predictors of poor outcomes in these patients. Pooled analysis showed obesity as a significant risk factor for intensive care unit admission (OR=1.547, CI=1.208–1.981, P=0.001) and intubation /mechanical ventilation (OR=1.744, CI=1.363–2.231 P=0.000). Therefore, BMI should be considered an important part of risk stratification, and vaccination should be prioritized for obese patients when it becomes widely available.

Abstract
Purpose The primary objective was to determine the feasibility of implementing the TrueNTH SHAReClinic as a pan-Canadian sexual health and rehabilitation intervention for patients treated for localized prostate cancer. Methods The feasibility study was designed to evaluate the accessibility and acceptability of the intervention. Participants from five institutions across Canada were enrolled to attend one pre-treatment and five follow-up online clinic visits over 1 year following their prostate cancer (PC) treatment. Results Sixty-five patients were enrolled in the intervention. Website analytics revealed that 71% completed the intervention in its entirety, including the educational modules, with an additional 10% completing more than half of the intervention. Five thousand eighty-three views of the educational modules were made along with 654 views of the health library items. Over 1500 messages were exchanged between participants and their sexual health coaches. At 12 months, the intervention received an overall average participant rating of 4.1 out of 5 on a single item satisfaction measure. Conclusion Results support the TrueNTH SHAReClinic as highly acceptable to participants as defined by intervention adherence and engagement. The TrueNTH SHAReClinic demonstrated promise for being a feasible and potentially resource-efficient approach to effectively improving the sexual well-being of patients after PC treatment.

Abstract
OBJECTIVE To survey OB-GYNs regarding their practice patterns and perspectives when it comes to using magnesium sulfate (magnesium) in the prevention of eclampsia. STUDY DESIGN We conducted a cross-sectional web-based 18-item survey given to 564 practicing OB-GYNs in the Pregnancy-Related Care Research Network. The survey used clinical scenarios to look at provider practices for preventing eclampsia in patients who have preeclampsia and relative contraindications to magnesium. Next, we assessed provider attitudes toward magnesium and inquired about their experiences with complications related to its use. The survey also contained an embedded educational component that addressed the signs and symptoms of magnesium toxicity followed by a 2-item quiz for those providers who self-identified as having never treated magnesium toxicity. RESULTS Nearly 30% of OB-GYNs contacted completed the survey. For patients with preeclampsia and a contraindication to magnesium such as myasthenia gravis, 44.4% of respondents would administer an alternative antiepileptic and 42.5% of them would administer no antiepileptic at all. For patients with pulmonary edema complicating preeclampsia, 32.5% would give magnesium at the usual dose, 33.1% would give magnesium at less than the usual dose, 12.3% would give an alternative antiepileptic and 22.1% would give no antiepileptic at all. For patients with laboratory evidence of renal compromise complicating preeclampsia, most respondents (89.6%) said they would give magnesium at less than the usual dose. Regarding complications of magnesium that clinicians have encountered, over one-third of respondents have administered calcium gluconate for magnesium toxicity in patients with preeclampsia. For those providers who have not treated magnesium toxicity and were prompted to receive the educational component and quiz, all knew the correct initial bolus dosing of magnesium and the majority were able to identify symptoms of toxicity. The majority (81.8%) of respondents said that continuous magnesium infusions cause an increased demand for dedicated personnel to care for the patients on them. Almost 57% of respondents endorsed the need for an alternative antiepileptic to magnesium in the prevention of eclampsia. Most write-in responses supporting this need cited a concern with magnesium's safety and side effects. CONCLUSION There is wide variation among OB-GYNs regarding the prevention of eclampsia and complications of magnesium are not uncommon. The survey revealed that OB-GYNs are using alternative antiepileptics in scenarios where there is concern for magnesium's safety profile. In addition, over half of those surveyed believe there is a need for validated antiepileptics other than magnesium for the prevention of eclampsia in patients with preeclampsia. These findings suggest that OB-GYNs would support further research into alternative antiepileptics in the prevention of eclampsia.

Abstract
Night-blind individuals often have restricted visual fields or other visual impairments that limit their ability to travel at night. The study reported here compared two night-vision devices: one wide-angle light and one with a high-intensity beam. It concluded that no one night light is best for all individuals and that depending on the cause of the night blindness, a smaller angle, high-intensity light may be more useful than a wider angle one.

Abstract
Background:The biologic drug Rituximab (anti-CD20) is used therapeutically in SLE, however the clinical response to the therapy, which is expensive, is quite variable. Factors influencing the efficacy have been challenging to determine. The MRC funded MASTERPLANS consortium has investigated prognostic factors that determine the therapeutic response to biologic therapy in SLE. Genetics has not been studied on a large scale in this context. SLE is a complex clinical phenotype, it is likewise a complex genetic trait, although it has recently been shown that polygenic risk scores do have a relationship to the severity of the disease (1). In addition, genetic risk factors for SLE, coded at the IgG Fc gamma receptor locus, have the potential to influence antibody-dependent cell-mediated cytotoxicity.Objectives:To determine whether the genetics influences the clinical outcome of therapy with Rituximab. The study used both genome-wide data in the form of genetic risk scores as well as specific genetic data at a candidate locus, namely the IgG Fc gamma receptor locusMethods:Samples from the BILAG Biologics Register (BILAG BR) of individuals treated with Rituximab were subject to genome-wide genotyping with Illumina GSA V2 chip. Genetic risk scores (GRS) were calculated through a weighted risk sum. Genetic variation at the IgG Fc gamma receptor locus is not captured well on genotyping chips and hence common coding and copy number variation was studied using Multiplex Ligation-dependent Probe Amplification (MLPA) and sequencing.Results:BILAG-BR samples for SLE part of receiving Rituximab therapy were genotyped on GSA chip, 573 samples passed QC and were used in principal components analysis (PCA), among them, 310 samples both have RTX treatment information and GRS calculated. Examining the population using PCA in the informative samples revealed that the largest distinction, European versus African ancestry did not correlate with Rituximab response. When GRS was determined in the Responders versus the Non-responders there was a weak correlation with those with a higher risk score showing a tendency to be in the responder group (Fig. 1). We also examined variation at the IgG Fc gamma receptor locus, polymorphisms of which are associated with SLE and have been correlated with therapeutic outcome in lymphoma (2). In a subset of the BILAG-BR cohort, we show that carriage of the SLE risk allele atFCGR3A(158F) was enriched in the ‘responder at some point’ group compared to the non-responder group (P=0.03, Chi-square).Conclusion:We present preliminary data indicating that genetics at both the genome wide level and at theFCGRlocus show some influence on the outcome of therapy with Rituximab in SLE; more data are required in order to draw firm conclusions.References:[1]Reid S et al.

Abstract
Six foods representing a variety of food products were analyzed by the Assurance Listeria polyclonal enzyme immunoassay (EIA) and by either the Bacteriological Analytical Manual or the U.S. Department of Agriculture culture method for detecting Listeria monocytogenes and related Listeria species. Samples of each food type, at each inoculation level, were analyzed simultaneously by both methods. A total of 19 laboratories representing federal government agencies and private industry in the United States and Canada participated. Food types were inoculated with Listeria species including L. monocytogenes, with the exception of 3 lots of green beans, which were naturally contaminated. During this study, 1764 samples and controls were analyzed and confirmed, of which 492 were positive and 947 were negative by both methods. There were 159 samples that were positive by culture method but negative by the EIA and 188 that were negative by culture method but positive by EIA. Twenty-two samples were negative by EIA and by culture method but confirmed positive when Assurance selective enrichment broths were subcultured to selective agar. The Assurance polyclonal EIA for detecting L. monocytogenes and related Listeria species in foods has been adopted first action by AOAC INTERNATIONAL.

Abstract
Abstract
An interlaboratory study of a graphite furnace atomic absorption spectrophotometry (GFAAS) method for the determination of lead in wine was conducted. Seventeen laboratories from France, United States, and the United Kingdom, using a variety of GFAAS instruments, took part in the study. The method incorporated a novel matrix-matching procedure to minimize matrix effects between standards and samples. Six wine test materials were prepared and sent to participants as 12 blind duplicate or split level samples. There was good agreement between results obtained from participants and target values (24–279 μg/L) obtained with an inductively coupled plasma-mass spectrometry method. The precision of the GFAAS method was well within the range predicted by the Horwitz equation for the 6 test materials analyzed. Repeatability standard deviations ranged from 3 to 17%. Reproducibility standard deviations were in the range of 10 to 30%. The method is recommended for use for official purposes.

Abstract
The Coli Complete® substrate supporting disc (SSD) method for simultaneous confirmed total coliform count and Escherichia coli determination in all foods was compared with AOAC most probable number (MPN) methods, 966.23 and 966.24. Twenty-nine laboratories participated in this collaborative study in which 6 food types were analyzed. Four food types, raw ground beef, pork sausage, raw liquid milk, and nut meats, were naturally contaminated with coliform bacteria. Two foods, dry egg and fresh frozen vegetables, were seeded with coliforms. Three food types, ground beef, raw liquid milk, and pork sausage, were naturally contaminated with E. coli. Although pork sausage was naturally contaminated, the level was very low (<10/50 g); therefore, additional E. coli were inoculated into 1 lot of this food type. Three food types, nut meats, dry egg, and fresh frozen vegetables, were inoculated with E. coli. For naturally contaminated samples, duplicate determinations were made on 3 separate lots for each food type. For inoculated samples, low, medium, and high contamination levels plus uninoculated control samples were examined in duplicate. Data were analyzed separately for total coliform bacteria and for E. coli. Mean log MPN counts were determined by the SSD method and the appropriate AOAC MPN method. Results were then analyzed for repeatability, reproducibility, and mean log MPN statistical equivalence. Results were statistically equivalent for all total coliform levels in all food types except frozen vegetable and raw nut meat uninoculated control samples and 1 lot of pork sausage where the SSD method produced statistically significant greater numbers. For the E. coli determinations, results were statistically equivalent across all samples and all levels for each food type. The SSD method has been adopted first action by AOAC International for confirmed detection of total coliforms and E. coli in all foods.

Abstract
A collaborative study was performed in 18 laboratories to validate use of Rappaport-Vassiliadis (RV) medium in the standard culture method for recovery of Salmonella spp. from raw, highly contaminated foods and poultry feed. RV medium made from its individual ingredients and incubated at 42�C was compared with selenite cystine (SC) broth incubated at 35�C and tetrathionate (TT) broth incubated at 35� and 43�C for effectiveness in recovery of Salmonella spp. Four artificially contaminated foods (oysters, frog legs, mushrooms, and shrimp) and poultry feed and one naturally contaminated food (chicken) were analyzed. The artificially contaminated foods were inoculated with single serovars of Salmonella at target levels of 0.04 colony-forming units (CFU)/g for the low level and 0.4 CFU/g for the high level. For analysis of 1125 test portions, RV medium (42�C) recovered Salmonellairom 409 test portions; TT (43�C), from 368 test portions; TT (35�C), from 310 test portions; and SC (35�C), from 334 test portions. Overall, RV medium was comparable with or better than other selective enrichments for recovery of Salmonella from the foods in this study, except mushrooms. From mushrooms, SC broth (35�C) recovered more positive test portions than did RV medium (42�C) and TT broth (43�C). The method for detection of Salmonella in raw, highly contaminated foods and

Abstract
Abstract
Background
Statins are now widely used for the primary prevention of atherosclerotic cardiovascular disease (ASCVD). However, existing risk prediction models were developed primarily on patients not on statins. We developed a novel model to estimate the risk of ASCVD among contemporary patients taking statins.
Methods
Using combined data from 3 large NIH-sponsored cohort studies: Atherosclerosis Risk in Communities, Framingham Offspring Study, and Multi-ethnic Study of Atherosclerosis we examined adults aged 40–79 years without prior ASCVD who were on statin therapy at the baseline exam. A Cox proportional hazards model was used to identify factors associated with a 10-year risk of CV death, MI, or stroke. Age, sex, and race were forced into the model while other potential candidate predictors were retained if statistically significant at the 0.05 level. Interaction terms with age, sex, and race were retained if significant at the 0.01 level. The model was assessed with c-statistic and calibration plots of observed events versus model-based risks after cross-validation and contrasted with the Pooled Cohorts Equations (PCE) recommended by the current U.S. guidelines.
Results
Among 2333 primary prevention patients on statins at baseline, a total of 220 events occurred over a median 8.8 years of follow-up. Most risk factors retained in our final model overlapped with those included in the PCE (age, sex, race, systolic blood pressure [sBP], diabetes, smoking, high-density lipoprotein cholesterol, total cholesterol). Our model also included creatinine clearance, aspirin use, and the interaction between age and sBP. Optimism-corrected discrimination of the new model was marginally higher than PCE: 0.69 (95% CI 0.66–0.72) versus 0.68 (95% CI 0.65–0.72). Cross-validated calibration was superior on our contemporary sample, especially at the higher levels of risk (Figure), where PCE over-estimated risk.
Calibration plots
Conclusion
Accurate estimation of 10-year ASCVD risk among patients currently on statins necessitates recalibration of the current PCE model or application of our algorithm developed specifically for this cohort. This might help avoid over-estimation of risk and reduce the need for unnecessary additional lipid-lowering therapy.

Abstract
Background English Stop Smoking Services primarily deliver behavioural interventions to support abrupt quit attempts. Recent evidence suggests an alternative approach could be offered to clients involving a more gradual reduction of cigarettes smoked leading to complete abstinence, known as ‘Cut Down To Stop’ (CDTS). The purpose of this study was to explore the experiences of stop smoking practitioners and service users who participated in a pilot study of a CDTS service. Methods The CDTS intervention was pilot tested in a Stop Smoking Service in London, England. As part of the CDTS intervention clients who were still smoking 2 weeks after their quit date were offered tailored advice, medication and support to reduce their current smoking by half, with the aim to stop smoking altogether within a six-month period. A qualitative evaluation was conducted involving a focus group discussion with nine practitioners involved in the delivery of the CDTS intervention and telephone interviews with 18 CDTS service users. Thematic analysis was performed. Results Service users and practitioners were very positive about their experience with the CDTS intervention. The intervention was found to be an effective way of keeping clients engaged with the service and was felt to increase the likelihood they might quit and/or re-engage in service for future quit attempts. Elements that contributed to the attractiveness of the CDTS intervention included: 1) the trust and empathetic relationship developed between service users, practitioners and their referring primary care provider; 2) time and flexibility for service users to engage in the quitting process at their own pace; 3) setting progressive goals and building service user confidence; 4) the opportunity to experiment with quit smoking medications; and, 5) the on-going contact with the practitioner/service. Conclusions Service users who are not successful with quitting abruptly may benefit from a CDTS intervention. This study highlights the important role of ‘relationships’, time and ‘flexible’ service delivery models in engaging service users who are not initially successful with quitting. The findings of this study have the potential to inform decision-making regarding the value of the CDTS approach for the English Stop Smoking Service and cessation services worldwide.
