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
Abstract
The red wolf (Canis rufus), a legally recognized and critically endangered wolf, is known to interbreed with coyotes (Canis latrans). Declared extirpated in the wild in 1980, red wolves were reintroduced to northeastern North Carolina nearly a decade later. Interbreeding with coyotes was thought to be restricted to a narrow geographic region adjacent to the reintroduced population and largely believed to threaten red wolf recovery. However, red wolf ancestry was recently discovered in canids along the American Gulf Coast, igniting a broader survey of ancestry in southeastern canid populations. Here, we examine geographic and temporal patterns of genome-wide red wolf ancestry in 260 canids across the southeastern United States at over 164 000 SNP loci. We found that red wolf ancestry was most prevalent in canids sampled from Texas in the mid-1970s, although non-trivial amounts of red wolf ancestry persist in this region today. Further, red wolf ancestry was also observed in a subset of coyotes inhabiting North Carolina, despite management efforts to limit the occurrence of hybridization events. Lastly, we found no evidence of substantial red wolf ancestry in southeastern canids outside of these 2 admixture zones. Overall, this study provides a genome-wide survey of red wolf ancestry in canids across the southeastern United States, which may ultimately inform future red wolf restoration efforts.

Abstract
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.

Robinson J, McEwen A, Heah R, Papadakis S. A 'Cut-Down-To-Stop' intervention for smokers who find it hard to quit: a qualitative evaluation. BMC Public Health 2019; 19:403. [PMID: 30987623 PMCID: PMC6466646 DOI: 10.1186/s12889-019-6738-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2018] [Accepted: 04/02/2019] [Indexed: 11/10/2022] Open
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.
