Wide dispersion of B chromosomes in Rhammatocerus brasiliensis (Orthoptera, Acrididae)

Abstract The grasshopper Rhammatocerus brasiliensis shows polymorphism of B chromosomes, but the magnitude of B-chromosome occurrence and the factors that may contribute to their dispersion in the species remain unknown thus far. The present study analyzed the occurrence and dispersion of B chromosomes in R. brasiliensis individuals from 21 populations widely distributed in the Brazilian Northeast. The genetic connectivity between 10 populations was verified through analysis of ISSR markers from 200 individuals. Of the 21 populations, 19 presented individuals with one B chromosome, three with two, and one with three B chromosomes. The B chromosome is of medium size and constitutive heterochromatin (CH) located in the pericentromeric region. A variant B chromosome was observed in three populations, similar in size to that of chromosome X, gap and CH, and located in the terminal region. B chromosome frequencies in different populations varied from 0% to 18,8%, mean 8,5%. The wide distribution of the B chromosome is likely a consequence of the positive gene flow among the analyzed populations. B-chromosome occurrence in populations of R. brasiliensis possibly follows the population genetic structure of the species and, owing to the existence of a variant, its origin may not be recent.
Association Between Healthy Eating Patterns and Risk of Cardiovascular Disease.

Importance The 2015-2020 Dietary Guidelines for Americans recommend multiple healthy eating patterns. However, few studies have examined the associations of adherence to different dietary patterns with long-term risk of cardiovascular disease (CVD). Objective To examine the associations of dietary scores for 4 healthy eating patterns with risk of incident CVD. Design, Setting, and Participants Prospective cohort study of initially healthy women from the Nurses' Health Study (NHS) (1984-2016) and the NHS II (1991-2017) and men from the Health Professionals Follow-up Study (HPFS) (1986-2012). The dates of analysis were July 25 to December 4, 2019. Exposures Healthy Eating Index-2015 (HEI-2015), Alternate Mediterranean Diet Score (AMED), Healthful Plant-Based Diet Index (HPDI), and Alternate Healthy Eating Index (AHEI). Main Outcomes and Measures Cardiovascular disease events, including fatal and nonfatal coronary heart disease (CHD) and stroke. Results The final study sample included 74 930 women in the NHS (mean [SD] baseline age, 50.2 [7.2] years), 90 864 women in the NHS II (mean [SD] baseline age, 36.1 [4.7] years), and 43 339 men in the HPFS (mean [SD] baseline age, 53.2 [9.6] years). During a total of 5 257 190 person-years of follow-up, 23 366 incident CVD cases were documented (18 092 CHD and 5687 stroke) (some individuals were diagnosed as having both CHD and stroke). Comparing the highest with the lowest quintiles, the pooled multivariable-adjusted hazard ratios (HRs) of CVD were 0.83 (95% CI, 0.79-0.86) for the HEI-2015, 0.83 (95% CI, 0.79-0.86) for the AMED, 0.86 (95% CI, 0.82-0.89) for the HPDI, and 0.79 (95% CI, 0.75-0.82) for the AHEI (P for trend <.001 for all). In addition, a 25-percentile higher dietary score was associated with 10% to 20% lower risk of CVD (pooled HR, 0.80 [95% CI, 0.77-0.83] for the HEI-2015; 0.90 [95% CI, 0.87-0.92] for the AMED; 0.86 [95% CI, 0.82-0.89] for the HPDI; and 0.81 [95% CI, 0.78-0.84] for the AHEI). These dietary scores were statistically significantly associated with lower risk of both CHD and stroke. In analyses stratified by race/ethnicity and other potential risk factors for CVD, the inverse associations between these scores and risk of CVD were consistent in most subgroups. Conclusions and Relevance In 3 large prospective cohorts with up to 32 years of follow-up, greater adherence to various healthy eating patterns was consistently associated with lower risk of CVD. These findings support the recommendations of the 2015-2020 Dietary Guidelines for Americans that multiple healthy eating patterns can be adapted to individual food traditions and preferences.
Transmission of CJD from nasal brushings but not spinal fluid or RT‐QuIC product

The detection of prion seeding activity in CSF and olfactory mucosal brushings using real‐time quaking‐induced conversion assays allows highly accurate clinical diagnosis of sporadic Creutzfeldt–Jakob disease. To gauge transmission risks associated with these biospecimens and their testing, we have bioassayed prion infectivity levels in patients’ brain tissue, nasal brushings, and CSF, and assessed the pathogenicity of amplified products of real‐time quaking‐induced conversion assays seeded with Creutzfeldt–Jakob disease prions.
meta / contrib-group / affiliation / aff " parastyle " Affiliation " A telephone-based guided imagery tobacco cessation intervention : results of a randomized feasibility trial

Research: Future research should be aimed at establishing the efficacy of the guided imagery intervention versus and active standard cognitive behavioral control. College of Nursing, University of Arizona, Tucson, AZ, USA Mel and Enid Zuckerman College of Public Health, University of Arizona, Tucson, AZ, USA Department of Family and Community Medicine, University of Arizona, Tucson, AZ, USA College of Physical Activity and Sport Sciences and School of Public Health, West Virginia University, Morgantown, WV, USA Abstract Background: Evidence supports the use of guided imagery for smoking cessation; however, scalable delivery methods are needed to make it a viable approach. Telephone-based tobacco quitlines are a standard of care, but reach is limited. Adding guided imagery to quitline services might increase reach by offering an alternative approach. Purpose: To develop and test the feasibility and potential impact of a guided imagery-based tobacco cessation intervention delivered using a quitline model. Methods: Participants for this randomized feasibility trial were recruited statewide through a quitline or community-based methods. Participants were randomized to guided imagery Intervention Condition (IC) or active behavioral Control Condition (CC). After withdrawals, there were 105 participants (IC = 56; CC = 49). The IC consisted of six sessions in which participants created guided imagery audio files. The CC used a standard six-session behavioral protocol. Feasibility measures included recruitment rate, retention, and adherence to treatment. We also assessed 6-month quit rates and consumer satisfaction. Results: Both the IC and CC protocols were feasible to deliver. We finalized protocols and materials for participants, coaches and study staff, and delivered the protocols with fidelity. We developed successful recruitment methods, and experienced high retention (6 months = 81.9%) and adherence (all sessions = 66.7%). Long-term quit rates (IC = 27.9%; CC = 38.1%) compared favorably to those of quitlines, and program satisfaction was high, suggesting that the protocols are acceptable to smokers and may contribute to smoking abstinence. Conclusions: The guided imagery intervention is feasible and promising, suggesting that a fully powered RCT to test the efficacy of the intervention is warranted. Trial registration number: NCT02968381.
The Effectiveness of Silver Diamine Fluoride and Fluoride Varnish in Arresting Caries in Young Children and Associated Oral Health-Related Quality of Life.

OBJECTIVE To investigate the efficacy of silver diamine fluoride (SDF) with 5% fluoride varnish (FV) in treating cavitated caries in young children and to explore the association between SDF treatment and oral-health-related quality of life (OHRQoL). METHODS Children with active dentinal caries in primary teeth underwent treatment with 38% SDF and 5% FV at baseline and 4 months later. Treated lesions were assessed 4 and 8 months after baseline. Child-level analysis focused on classifying SDF treatment as completely successful if all of a child's treated lesions were arrested or incompletely successful if at least 1 lesion was not arrested. The Early Childhood Oral Health Impact Scale questionnaire was completed at second and third visits. Statistical analyses included descriptive and bivariate methods. A p value ≤ 0.05 was considered significant. RESULTS This pilot study enrolled 40 children with 239 caries lesions; mean age 40.2 ± 14.9 months and 45% male. Lesion arrest rates after 1 and 2 applications of SDF were 74.1% and 96.2%, respectively. Children who reportedly brushed twice daily were more likely to be in the completely successful group compared with those who brushed less (p = 0.006). Those in the completely successful group had a significantly lower mean baseline dmft score than those in the incompletely successful group (p = 0.048). No significant difference in OHRQoL was observed between the 2 groups. CONCLUSIONS SDF with 5% FV is an effective approach to the management of early childhood caries; more than 1 application is recommended, along with regular follow up of patients and twice daily brushing. OHRQoL was not found to be affected by the level of success of SDF treatment.
Plant resistance in different cell layers affects aphid probing and feeding behaviour during non-host and poor-host interactions

Abstract Aphids are phloem-feeding insects that cause economic losses to crops globally. Whilst aphid interactions with susceptible plants and partially resistant genotypes have been well characterized, the interactions between aphids and non-host species are not well understood. Unravelling these non-host interactions can identify the mechanisms which contribute to plant resistance. Using contrasting aphid-host plant systems, including the broad host range pest Myzus persicae (host: Arabidopsis; poor-host: barley) and the cereal pest Rhopalosiphum padi (host: barley; non-host: Arabidopsis), we conducted a range of physiological experiments and compared aphid settling and probing behaviour on a host plant vs either a non-host or poor-host. In choice experiments, we observed that around 10% of aphids selected a non-host or poor-host plant species after 24 h. Using the Electrical Penetration Graph technique, we showed that feeding and probing behaviours differ during non-host and poor-host interactions when compared with a host interaction. In the Arabidopsis non-host interaction with the cereal pest R. padi aphids were unable to reach and feed on the phloem, with resistance likely residing in the mesophyll cell layer. In the barley poor-host interaction with M. persicae, resistance is likely phloem-based as phloem ingestion was reduced compared with the host interaction. Overall, our data suggest that plant resistance to aphids in non-host and poor-host interactions with these aphid species likely resides in different plant cell layers. Future work will take into account specific cell layers where resistances are based to dissect the underlying mechanisms and gain a better understanding of how we may improve crop resistance to aphids.
Presurgical risk model for chronic postsurgical pain based on six clinical predictors: a prospective external validation.

No externally validated presurgical risk score for chronic postsurgical pain (CPSP) is currently available. We tested the generalizability of a six-factor risk model for CPSP developed from a prospective cohort of 2929 patients in four surgical settings. Seventeen centers enrolled 1225 patients scheduled for inguinal hernia repair, hysterectomy (vaginal or abdominal), or thoracotomy. The six clinical predictors were surgical procedure, younger age, physical health (Short Form Health Survey-12), mental health (Short Form Health Survey-12), preoperative pain in the surgical field, and preoperative pain in another area. CPSP was confirmed by physical examination at 4 months. The model's discrimination (c-statistic), calibration, and diagnostic accuracy (sensitivity, specificity and positive and negative likelihood ratios) were calculated to assess geographic and temporal transportability in the full cohort and two subsamples (historical and new centers). The full dataset after exclusions and losses included 1088 patients; 20.6% had developed CPSP at 4 months. The c-statistics (95% CI) were similar in the full validation sample and the two subsamples: 0.69 (0.65-0.73), 0.69 (0.63-0.74) and 0.68 (0.63-0.74), respectively. Calibration was good (slope b and intercept close to 1 and 0, respectively and nonsignificance in the Hosmer-Lemeshow goodness-of-fit test). The validated model based on six clinical factors reliably identifies risk for CPSP risk in about 70% of patients undergoing the surgeries studied, allowing surgeons and anesthesiologists to plan and initiate risk reduction strategies in routine practice and researchers to screen for risk when randomizing patients in trials.
Guidelines for Reporting of Figures and Tables for Clinical Research in Urology

In an effort to improve the presentation of and information within tables and figures in clinical urology research, we propose a set of appropriate guidelines. We introduce six principles: (1) include graphs only if they improve the reader’s ability to understand the study findings; (2) think through how a graph might best convey information, do not just select a graph from preselected options on statistical software; (3) do not use graphs to replace reporting key numbers in the text of a paper; (4) graphs should give an immediate visual impression of the data; (5) make it beautiful; and (6) make the labels and legend clear and complete. We present a list of quick “dos and don’ts” for both tables and figures. Investigators should feel free to break any of the guidelines if it would result in a beautiful figure or a clear table that communicates data effectively. That said, we believe that the quality of tables and figures in the medical literature would improve if these guidelines were to be followed.
Detection of adulteration in food based on nondestructive analysis techniques: a review

Abstract In recent years, people pay more and more attention to food quality and safety, which are significantly relating to human health. Food adulteration is a world-wide concerned issue relating to food quality and safety, and it is difficult to be detected. Modern detection techniques (high performance liquid chromatography, gas chromatography-mass spectrometer, etc.) can accurately identify the types and concentrations of adulterants in different food types. However, the characteristics as expensive, low efficient and complex sample preparation and operation limit the use of these techniques. The rapid, nondestructive and accurate detection techniques of food adulteration is of great and urgent demand. This paper introduced the principles, advantages and disadvantages of the nondestructive analysis techniques and reviewed the applications of these techniques in food adulteration screen in recent years. Differences among these techniques, differences on data interpretation and future prospects were also discussed.
Adolescents with asthma reported more peer victimization, more anger repression, and less anger expression

Abstract Objective The aim of this study was to investigate the peer victimization and anger expression in adolescents with asthma. The relationship between asthma control and psychological features was also examined. Methods The study was a cross-sectional study with a healthy control group. The sample of the study was composed of 61 adolescents who were previously diagnosed by a physician with asthma of various intensities. Sixty adolescents with no chronic disorders were enrolled as the control group. Peer victimization was examined using the Multidimensional Peer Victimization Scale (MPVS). The State-Trait Anger Expression Inventory (STAXI) was used to assess anger expression styles. Emotional and behavioral symptoms of the adolescents were measured using the Strengths and Difficulties Questionnaire (SDQ). Results Adolescents with asthma reported more peer victimization in the subscales of physical, social, verbal, attacks on property, and frightening in the MPVS; and having more problems in emotional, social, and peer relations areas in the SDQ (p < .001 for all subscales) compared to the control group. The results were similar between the groups regarding the conduct problems and hyperactive behaviors. The adolescents with asthma reported more anger repression and less anger expression than the control group (p < .001 for both subscales). Conclusions The results indicated that the adolescents with asthma were subjected to more peer victimization and experienced more difficulties in anger expression than the controls. Based on the findings of this study, we suggest that these psychological factors should be kept in mind during the management of asthma in adolescents.
Accurate determination of γδ T cells in multichannel mass and flow cytometry

To the Editor, In order to better discuss the excellent and well thought-out points made by Nicola Beucke in his “Accurate determination of γδ T cells in multi-channel mass and flow cytometry” letter to the editor, I have taken the liberty of arbitrarily rendering a Cen-se' map from one of the whole blood-derived files presented in the mass cytometry reproducibility study (Bagwell, Hunsberger et al., 2019, Site 2–1). Cen-se' maps are produced by a stochastic embedding methodology that minimizes the loss of neighborhood information in the mapping process. The Cen-se' map's loss is typically less than 5 to 10% which has been shown to be lower than equivalent t-Distributed Stochastic Neighbor Embedding maps (Bagwell, Bray, et al., 2019). Figure 1a shows a frequency-based heatmap for all the cell types except for neutrophils in the sample. The map leverages all 30 markers in positioning the events and because of its high resolution, it typically separates the major cell types into distinct and nonoverlapping clusters. Since the events have already been classified independently by the probability state modeling system (Bagwell et al., 2015) in the Pathsetter software, labels and percentages are conveniently shown at respective median x and y locations within the map. Panel B shows the same data with a TCRγδ B1 intensity heatmap and panels C and D show the CD4 and CD8 intensity heatmaps. The top 10 marker intensities within this file's TCRγδ-labeled cell type are as follows:
The ATGL lipase cooperates with ABHD5 to mobilize lipids for hepatitis C virus assembly

Lipid droplets are essential cellular organelles for storage of fatty acids and triglycerides. The hepatitis C virus (HCV) translocates several of its proteins onto their surface and uses them for production of infectious progeny. We recently reported that the lipid droplet-associated α/β hydrolase domain-containing protein 5 (ABHD5/CGI-58) participates in HCV assembly by mobilizing lipid droplet-associated lipids. However, ABHD5 itself has no lipase activity and it remained unclear how ABHD5 mediates lipolysis critical for HCV assembly. Here, we identify adipose triglyceride lipase (ATGL) as ABHD5 effector and new host factor involved in the hepatic lipid droplet degradation as well as in HCV and lipoprotein morphogenesis. Modulation of ATGL protein expression and lipase activity controlled lipid droplet lipolysis and virus production. ABHD4 is a paralog of ABHD5 unable to activate ATGL or support HCV assembly and lipid droplet lipolysis. Grafting ABHD5 residues critical for activation of ATGL onto ABHD4 restored the interaction between lipase and co-lipase and bestowed the pro-viral and lipolytic functions onto the engineered protein. Congruently, mutation of the predicted ABHD5 protein interface to ATGL ablated ABHD5 functions in lipid droplet lipolysis and HCV assembly. Interestingly, minor alleles of ABHD5 and ATGL associated with neutral lipid storage diseases in human, are also impaired in lipid droplet lipolysis and their pro-viral functions. Collectively, these results show that ABHD5 cooperates with ATGL to mobilize triglycerides for HCV infectious virus production. Moreover, viral manipulation of lipid droplet homeostasis via the ABHD5-ATGL axis, akin to natural genetic variation in these proteins, emerges as a possible mechanism by which chronic HCV infection causes liver steatosis.
Sonority-Related Novel Word Learning Ability of Children With Cochlear Implants With Optimal Oral Language Exposure.

OBJECTIVES The present study investigated how children with cochlear implants (CIs), with optimal exposure to oral language, perform on sonority-related novel word learning tasks. By optimal oral language exposure, we refer to bilateral cochlear implantation below the age of 2 years. Sonority is the relative perceptual prominence/loudness of speech sounds of the same length, stress, and pitch. The present study is guided by a previous study that investigated the sonority-related novel word learning ability of a group of children with CIs, in the Greek language, of which the majority were implanted beyond the age of 2 unilaterally. DESIGN A case-control study with 15 Dutch-speaking participants in each of the three groups, i.e., children with CIs, normal-hearing children (NHC), and normal-hearing adults, was conducted using a sonority-related novel "CVC" word learning task. All children with CIs are implanted before the age of 2 years with preimplant hearing aids. Thirteen out of the 15 children had bilateral CIs. The CVC words were constructed according to four sonority conditions, where N is nonsonorous and S is a sonorous phoneme: NSN, NSS, SSN, and SSS. Outcome measures were accuracy and reaction times (RTs). In addition, the Peabody picture vocabulary test and the digit span forward test were administered to the children. RESULTS There were no statistical differences in accuracy or RTs between the children groups on the overall score and across the different conditions. However, children with CIs, unlike NHC, scored statistically less accurately and with longer RTs relative to normal-hearing adults, on the overall task. Within-group comparisons showed that none of the groups performed statistically differently on any of the conditions. The NHC showed higher receptive vocabulary scores relative to children with CIs. In addition, the group of children with CIs entailed a statistically significantly higher number of children with "weak" short-term memory. CONCLUSIONS Children with CIs who have optimal oral language exposure showed age-appropriate sonority-related novel word learning abilities and strategies relative to their NH peers. However, children with CIs continue to show lower receptive vocabulary scores than NHC, despite the equivalent novel word learning ability. This suggests that children with CIs may have difficulties in retaining newly learned words. Future work should look into possible causes of the gap in performance. This would eventually aid in rehabilitation tailored to the needs of the individual.
