RESUMO

Increasing understanding of the risk and protective factors for adolescent nonmedical use of prescription drugs (NMUPD) could inform prevention efforts. Several correlates have been identified, including parental factors, perceptions about use and accessibility, social norms, and age. However, these constructs have rarely been simultaneously examined using paired data from parents and adolescents. We aimed to examine the relative influence of these correlates among dyads (N=349) of mothers and adolescent daughters. Using multiple logistic regression, daughters' past NMUPD and inclination for future NMUPD were regressed onto descriptive norms for friend use, perceived drug accessibility and risk of harm from use, daughter age, mothers' disapproval about use, mothers' past NMUPD and inclination for future NMUPD, and the mother-daughter relationship quality. Akaike weights and lasso regressions were also estimated to evaluate the relative importance of each correlate. Higher descriptive norms for friend use, older age, and mothers' inclination for NMUPD were risk factors for daughters' NMUPD, while a closer mother-daughter relationship and mothers' disapproving attitudes towards NMUPD were protective factors. The three analysis approaches were corroborative. Results suggest friend descriptive norms, mother-daughter relationship quality, and mothers' attitudes about NMUPD are important prevention targets.

RESUMO

Background: Social media disseminated information and spread misinformation during the COVID-19 pandemic that affected prevention measures, including social distancing and vaccine acceptance. Objective: In this study, we aimed to test the effect of a series of social media posts promoting COVID-19 nonpharmaceutical interventions (NPIs) and vaccine intentions and compare effects among 3 common types of information sources: government agency, near-peer parents, and news media. Methods: A sample of mothers of teen daughters (N=303) recruited from a prior trial were enrolled in a 3 (information source) × 4 (assessment period) randomized factorial trial from January to March 2021 to evaluate the effects of information sources in a social media campaign addressing NPIs (ie, social distancing), COVID-19 vaccinations, media literacy, and mother-daughter communication about COVID-19. Mothers received 1 social media post per day in 3 randomly assigned Facebook private groups, Monday-Friday, covering all 4 topics each week, plus 1 additional post on a positive nonpandemic topic to promote engagement. Posts in the 3 groups had the same messages but differed by links to information from government agencies, near-peer parents, or news media in the post. Mothers reported on social distancing behavior and COVID-19 vaccine intentions for self and daughter, theoretic mediators, and covariates in baseline and 3-, 6-, and 9-week postrandomization assessments. Views, reactions, and comments related to each post were counted to measure engagement with the messages. Results: Nearly all mothers (n=298, 98.3%) remained in the Facebook private groups throughout the 9-week trial period, and follow-up rates were high (n=276, 91.1%, completed the 3-week posttest; n=273, 90.1%, completed the 6-week posttest; n=275, 90.8%, completed the 9-week posttest; and n=244, 80.5%, completed all assessments). In intent-to-treat analyses, social distancing behavior by mothers (b=-0.10, 95% CI -0.12 to -0.08, P<.001) and daughters (b=-0.10, 95% CI -0.18 to -0.03, P<.001) decreased over time but vaccine intentions increased (mothers: b=0.34, 95% CI 0.19-0.49, P<.001; daughters: b=0.17, 95% CI 0.04-0.29, P=.01). Decrease in social distancing by daughters was greater in the near-peer source group (b=-0.04, 95% CI -0.07 to 0.00, P=.03) and lesser in the government agency group (b=0.05, 95% CI 0.02-0.09, P=.003). The higher perceived credibility of the assigned information source increased social distancing (mothers: b=0.29, 95% CI 0.09-0.49, P<.01; daughters: b=0.31, 95% CI 0.11-0.51, P<.01) and vaccine intentions (mothers: b=4.18, 95% CI 1.83-6.53, P<.001; daughters: b=3.36, 95% CI 1.67-5.04, P<.001). Mothers' intentions to vaccinate self may have increased when they considered the near-peer source to be not credible (b=-0.50, 95% CI -0.99 to -0.01, P=.05). Conclusions: Decreasing case counts, relaxation of government restrictions, and vaccine distribution during the study may explain the decreased social distancing and increased vaccine intentions. When promoting COVID-19 prevention, campaign planners may be more effective when selecting information sources that audiences consider credible, as no source was more credible in general.

RESUMO

In a social media campaign aimed at reducing mothers' permissiveness for indoor tanning (IT) by their teenage daughters, a secondary analysis of campaign engagement effects on IT outcomes was performed. Mothers (n = 869) with daughters aged 14-17 were recruited in 34 states that did not ban IT by minors under age 18 for a randomized trial with follow-up at 12 months (end of intervention) and 18 months (6 months after intervention) post-randomization. Daughters' (n = 469) baseline and follow-up responses were analyzed too. Mothers received a Facebook feed on adolescent health topics that included posts about preventing IT (intervention) or prescription drug misuse (control). Engagement was measured by extracting reactions (e.g., like, sad, etc.) and comments posted by mothers to the campaign posts. Overall, 76.4% of posts received a reaction and/or comment. Mothers who engaged with IT posts were less permissive of daughters' IT immediately at the conclusion of the campaign (permit IT: -0.39, p < .05; facilitate IT: -0.29, p < .05) and 6 months after intervention (permit IT: -0.32, p < .05; facilitate IT: -0.31, p < .05) than mothers who did not engage with posts. Engagement with posts was essential to the success of a social media campaign for preventing IT by minors by reducing mothers' permissiveness.

RESUMO

BACKGROUND: A social media campaign for mothers aimed at reducing indoor tanning (IT) by adolescent daughters reduced mothers' permissiveness toward IT in an immediate posttest. Whether the effects persisted at 6 months after the campaign remains to be determined. METHODS: Mothers (N = 869) of daughters ages 14-17 in 34 states without bans on IT by minors were enrolled in a randomized trial. All mothers received an adolescent health campaign over 12 months with posts on preventing IT (intervention) or prescription drug misuse (control). Mothers completed a follow-up at 18 months post-randomization measuring IT permissiveness, attitudes, intentions, communication, and behavior, and support for state bans. Daughters (n = 469; 54.0%) just completed baseline and follow-up surveys. RESULTS: Structural equation modeling showed that intervention-group mothers were less permissive of IT by daughters [unstandardized coefficient, -0.17; 95% confidence interval (CI), -0.31 to -0.03], had greater self-efficacy to refuse daughter's IT requests (0.17; 95% CI, 0.06-0.29) and lower IT intentions themselves (-0.18; 95% CI, -0.35 to -0.01), and were more supportive of bans on IT by minors (0.23; 95% CI, 0.02-0.43) than control-group mothers. Intervention-group daughters expressed less positive IT attitudes than controls (-0.16; 95% CI, 0.31 to -0.01). CONCLUSIONS: The social media campaign may have had a persisting effect of convincing mothers to withhold permission for daughters to indoor tan for 6 months after its conclusion. Reduced IT intentions and increased support for bans on IT by minors also persisted among mothers. IMPACT: Social media may increase support among mothers to place more restrictions on IT by minors.

RESUMO

Introduction: Parents acquire information about human papillomavirus (HPV) vaccines online and encounter vaccine-critical content, especially on social media, which may depress vaccine uptake. Secondary analysis in a randomized trial of a Facebook-delivered adolescent health campaign targeting mothers with posts on HPV vaccination was undertaken with the aims of (a) determining whether the pre-post-change occurred in self-reports of the mothers on HPV vaccination of their adolescent daughters; (b) describing the comments and reactions to vaccine posts; (c) exploring the relationship of campaign engagement of the mothers assessed by their comments and reactions to posts to change in the self-reports of the mothers of HPV vaccination. Materials and Methods: Mothers of daughters aged 14-17 were recruited from 34 states of the US (n = 869). A social media campaign was delivered in two Facebook private groups that differed in that 16% of posts in one were focused on indoor tanning (IT) and 16% in the other, on prescription drug misuse, assigned by randomization. In both groups, posts promoted HPV vaccination (n = 38 posts; no randomization) and vaccination for other disease (e.g., influenza, n = 49). HPV and other vaccination posts covered the need for a vaccine, the number of adolescents vaccinated, how vaccines are decreasing the infection rates, and stories of positive benefits of being vaccinated or harms from not vaccinating. Guided by social cognitive theory and diffusion of innovations theory, posts were intended to increase knowledge, perceived risk, response efficacy (i.e., a relative advantage over not vaccinated daughters), and norms for vaccination. Some vaccination posts linked to stories to capitalize on identification effects in narratives, as explained in transportation theory. All mothers received the posts on vaccination (i.e., there was no randomization). Mothers completed surveys at baseline and 12- and 18-month follow-up to assess HPV vaccine uptake by self-report measures. Reactions (such as sad, angry) and comments to each HPV-related post were counted and coded. Results: Initiation of HPV vaccination (1 dose) was reported by 63.4% of mothers at baseline, 71.3% at 12-month posttest (pre/post p < 0.001), and 73.3% at 18-month posttest (pre/post p < 0.001). Completion of HPV vaccination (two or three doses) was conveyed by 50.2% of mothers at baseline, 62.5% at 12-month posttest (pre/post p < 0.001), and 65.9% at 18-month posttest (pre/post p < 0.001). For posts on HPV vaccines, 8.1% of mothers reacted (n = 162 total), and 68.4% of posts received a reaction (63.2% like; 13.2% love, 7.9% sad). In addition, 7.6% of mothers commented (n = 122; 51 unfavorable, 68 favorable, 1 neutral), and 50.0% of these posts received a comment. There were no differences in pre-post change in vaccine status by the count of reactions or comments to HPV vaccine posts (Ps > 0.05). Baseline vaccination was associated with the valence of comments to HPV vaccine posts (7.2% of mothers whose daughters had completed the HPV series at baseline made a favorable comment but 7.6% of mothers whose daughters were unvaccinated made an unfavorable comment). Conclusion: Effective strategies are needed in social media to promote HPV vaccines and counter misinformation about and resistance to them. Mothers whose daughters complete the HPV vaccine course might be recruited as influencers on HPV vaccines, as they may be predisposed to talk favorably about the vaccine. Comments from mothers who have not been vaccinated should be monitored to ensure that they do not spread vaccine-critical misinformation. Study limitations included lack of randomization and control group, relatively small number of messages on HPV vaccines, long measurement intervals, inability to measure views of vaccination posts, reduced generalizability related to ethnicity and social media use, and use of self-reported vaccine status.

RESUMO

Indoor tanning (IT) increases risk of developing skin cancer. A social media campaign to reduce mother's permissiveness toward their teenage daughters IT was evaluated. Mothers (N = 869) of daughters aged 14-17 in 34 states without bans on IT by minors were enrolled in a randomized trial with assessments at baseline and 12-months follow-up in 2017-19. A year-long adolescent health campaign was delivered to all mothers. The intervention group received posts on preventing IT and the control group, posts about preventing prescription drug misuse. Daughters (n = 469; 54.0%) completed the assessments at baseline and 12 months. At 12-month follow-up, intervention-group mothers were less permissive of IT by daughters (unadjusted means = 1.70 [95% CI: 1.59, 1.80] v. 1.85 [1.73, 1.97] [5-point Likert scale], b = -0.152), reported more communication about avoiding IT with daughters (4.09 [3.84, 4.35] v. 3.42 [3.16, 3.68] [sum of 7 yes/no items], b = 0.213), and had lower intentions to indoor tan (1.41 [1.28, 1.55] v. 1.60 [1.43, 1.76] [7-point likelihood scale], b = -0.221) than control-group mothers. Daughters confirmed intervention-group mothers communicated about IT (3.81 [3.49, 4.14] v. 3.20 [2.87, 3.53] [sum of 7 yes/no items], b = 0.237) and shared IT posts (unadjusted percentages = 52.4% v. 36.4%, b = 0.438) more than control-group mothers. No differences were found in IT behavior, self-efficacy to refuse permission, and negative attitudes toward IT. A social media campaign may be an effective strategy to convince mothers to withhold permission for IT, which may help increase the effectiveness of state laws designed to reduce IT by minors by requiring parental permission.

RESUMO

BACKGROUND: Unintended pregnancies remain an important public health issue. Modern contraception is an important clinical service for reducing unintended pregnancy. This study examines contraception use among a representative sample of women residing in two southeastern U.S. states. METHODS: A cross-sectional statewide survey assessing women's contraceptive use and reproductive health experiences was conducted in Alabama and South Carolina. Characteristics of the study population were compared across contraceptive use categories and multivariable regression analysis was performed examining relationships between covariates of interest and contraceptive use outcomes. RESULTS: Approximately 3,775 women were included in the study population. Overall, 26.5% of women reported not using any contraception. Short-acting hormonal methods were the most commonly reported (26.3%), followed by permanent methods (24.4%), long-acting reversible contraception (LARC; 14.3%), and barrier/other methods (8.5%). Nonuse was more prevalent among women with some college or an associate's degree, incomes between $25,000 and $50,000, no health insurance, and longer gaps in care. LARC use among women with Medicaid as a pay source was higher than use among privately insured women and higher in South Carolina than Alabama. Both nonuse and LARC use were higher among women with no insurance. CONCLUSIONS: Study findings are largely consistent with previous research using similar population-based surveys. LARC use was higher among the study population relative to what is observed nationally. Factors enabling access to contraceptive services, particularly for lower income women, were associated with contraception use patterns. These findings provide important context for understanding individuals' access to resources and are important for fostering increased access to contraceptive services among women in these two states.

RESUMO

The identification of immune receptors in crop plants is time-consuming but important for disease control. Previously, resistance gene enrichment sequencing (RenSeq) was developed to accelerate mapping of nucleotide-binding domain and leucine-rich repeat containing (NLR) genes. However, resistances mediated by pattern recognition receptors (PRRs) remain less utilized. Here, our pipeline shows accelerated mapping of PRRs. Effectoromics leads to precise identification of plants with target PRRs, and subsequent RLP/K enrichment sequencing (RLP/KSeq) leads to detection of informative single nucleotide polymorphisms that are linked to the trait. Using Phytophthora infestans as a model, we identified Solanum microdontum plants that recognize the apoplastic effectors INF1 or SCR74. RLP/KSeq in a segregating Solanum population confirmed the localization of the INF1 receptor on chromosome 12, and led to the rapid mapping of the response to SCR74 to chromosome 9. By using markers obtained from RLP/KSeq in conjunction with additional markers, we fine-mapped the SCR74 receptor to a 43-kbp G-LecRK locus. Our findings show that RLP/KSeq enables rapid mapping of PRRs and is especially beneficial for crop plants with large and complex genomes. This work will enable the elucidation and characterization of the nonNLR plant immune receptors and ultimately facilitate informed resistance breeding.

RESUMO

Background: Prescription drug abuse is a public health problem in the United States and the region of Appalachia, specifically. Primary care and addiction medicine-as possible points of access for prescription drugs with abuse potential and points of intervention for prescription drug abuse-are among the medical fields at its forefront. Little is known, however, about perceptions of prescription drug abuse across the two patient populations. Objectives: The objective of this qualitative analysis was to explore perceptions of the scale and context of prescription drug abuse among primary care and addiction medicine patients in Appalachia. Methods: As part of a mixed methods study, semi-structured interviews were conducted with 20 patients from primary care and addiction medicine in Central and South Central Appalachia from 2014 to 2015. The interviews were audio-recorded and transcribed verbatim. Thematic analysis was used to identify themes. Results: Three themes were identified: (1) pervasiveness of prescription drug abuse, describing perceptions of its high prevalence and negative consequences; (2) routes and routine practices for prescription drug acquisition and distribution, describing perceptions of routes of access to prescription drugs and behaviors exhibited to acquire and distribute prescription drugs; and (3) rationales for prescription drug acquisition and distribution, describing perceptions of the two underlying reasons for these processes-tolerance/addiction and revenue source. Conclusions/Importance: Perceptions of prescription drug abuse among primary care and addiction medicine patients in Appalachia are multifaceted, especially regarding prescription drug acquisition and distribution. Clinical practice implications for mitigating prescription drug abuse are discussed.

RESUMO

Background: Provider-patient communication underpins many initiatives aimed at reducing the public health burden associated with prescription drug abuse in the United States. The purpose of this qualitative analysis was to examine the characteristics of provider-patient communication about prescription drug abuse from the perspective of prescribers. Methods: From 2014 to 2015, 10 semi-structured interviews were conducted with a purposive sample of prescribers from multiple professions and medical fields in Central and South Central Appalachia. The interviews were conducted using a guide informed by Social Cognitive Theory and community theory research, audio-recorded, and transcribed verbatim. Thematic analysis, facilitated by NVivo 10 software, was used to generate themes. Results: Prescribers described 3 primary communication patterns with patients related to prescription drug abuse-informative, counteractive, and supportive. Prescribers also reported multiple factors-personal (e.g., education, experiences, and feelings of tension) and environmental (e.g., relationship with a patient, clinical resources, and policies on controlled prescription drugs)-that affect provider-patient communication and, by association, delivery of patient care related to prescription drug abuse. Conclusions: The findings suggest that provider-patient communication about prescription drug abuse is multidimensional and dynamic, characterized by multiple communication patterns and contributory factors. They have implications for (1) research aimed at advancing theoretical understanding of prescriber prescription drug abuse communication behaviors with patients and (2) interventions aimed at strengthening prescriber prescription drug abuse communication behaviors with patients.

RESUMO

Association of Mycoplasma ovipneumoniae with pneumonia in domestic small ruminants has been described in Europe, Asia, and New Zealand but has received less attention in the United States. In 2011, the US Department of Agriculture's National Animal Health Monitoring System detected M. ovipneumoniae shedding in 88% of 453 domestic sheep operations tested in 22 states that accounted for 85.5% of US ewe inventory in 2001. We evaluated factors associated with M. ovipneumoniae infection presence and prevalence, and we compared health, lamb production, and ewe losses in infected and uninfected operations. M. ovipneumoniae detection was more common in larger operations than in smaller operations. Both likelihood of detection (at the operation level) and within-operation prevalence were higher in operations with more open management practices than in operations with more closed management practices. M. ovipneumoniae-positive operations showed significantly lower lambing rates and lower rates of lamb survival to weaning after accounting for differences in operation size and management practice. While its effect on any single rate was not particularly large, in aggregate we estimated that M. ovipneumoniae presence was associated with an approximately 4.3% reduction in annual lamb production.

RESUMO

In the United States, parents' health beliefs affect HPV vaccination decisions for children. Our team acquired insights into mothers' health beliefs from their reactions and comments to posts on HPV vaccination in a social media adolescent health campaign in a randomized trial (n = 881 mothers; 63.1% reported daughters had 1+ doses of the HPV vaccine) evaluating communication intended to reduce daughters' indoor tanning. A total of 10 HPV vaccination messages in didactic (n = 7) and narrative (n = 3) formats were posted on vaccination need, uptake, and effectiveness and stories of young women who died from cervical cancer and a mother's decision to vaccinate her daughters. These posts received 28 reactions (like, love, and sad buttons; mean = 2.8 per post) and 80 comments (mean = 8.0 per post). More comments were favorable (n = 43) than unfavorable (n = 34). Data was not collected on views for posts. The most common favorable comment reported that daughters were vaccinated (n = 31). Unfavorable comments cited safety concerns, lack of physician support, distrust of pro-vaccine sources, and increased sexual activity of daughters. Mothers posting unfavorable (18.2%) as opposed to favorable (78.6%) comments or not commenting (64.0%) were less likely to have had their daughters vaccinated (chi-square = 22.27, p < 0.001). Favorable comments often did not state reasons for vaccinating. Concerns about lack of vaccine safety remain a barrier. Mothers may express distrust in pro-vaccine sources to reduce discomfort with not vaccinating daughters to reduce their risk for HPV infection. Many mothers who remained silent had vaccinated daughters, which suggests they did not resisit HPV vaccination.

RESUMO

KEY MESSAGE: The nematode resistance gene H2 was mapped to the distal end of chromosome 5 in tetraploid potato. The H2 resistance gene, introduced into cultivated potatoes from the wild diploid species Solanum multidissectum, confers a high level of resistance to the Pa1 pathotype of the potato cyst nematode Globodera pallida. A cross between tetraploid H2-containing breeding clone P55/7 and susceptible potato variety Picasso yielded an F1 population that segregated approximately 1:1 for the resistance phenotype, which is consistent with a single dominant gene in a simplex configuration. Using genome reduction methodologies RenSeq and GenSeq, the segregating F1 population enabled the genetic characterisation of the resistance through a bulked segregant analysis. A diagnostic RenSeq analysis of the parents confirmed that the resistance in P55/7 cannot be explained by previously characterised resistance genes. Only the variety Picasso contained functionally characterised disease resistance genes Rpi-R1, Rpi-R3a, Rpi-R3b variant, Gpa2 and Rx, which was independently confirmed through effector vacuum infiltration assays. RenSeq and GenSeq independently identified sequence polymorphisms linked to the H2 resistance on the top end of potato chromosome 5. Allele-specific KASP markers further defined the locus containing the H2 gene to a 4.7 Mb interval on the distal short arm of potato chromosome 5 and to positions that correspond to 1.4 MB and 6.1 MB in the potato reference genome.

RESUMO

Twitter may be useful for learning about indoor tanning behavior and attitudes. The objective of this study was to analyze the content of tweets about indoor tanning to determine the extent to which tweets are posted by people who tan, and to characterize the topics of tweets. We extracted 4,691 unique tweets from Twitter using the terms "tanning bed" or "tanning salon" over 7 days in March 2016. We content analyzed a random selection of 1,000 tweets, double-coding 20% of tweets (κ = 0.74, 81% agreement). Most tweets (71%) were by tanners (n = 699 individuals) and included tweets expressing positive sentiment about tanning (57%), and reports of a negative tanning experience (17%), burning (15%), or sleeping in a tanning bed (9%). Four percent of tweets were by tanning salon employees. Tweets posted by people unlikely to be tanners (15%) included tweets mocking tanners (71%) and health warnings (29%). The term "tanning bed" had higher precision for identifying individuals who engage in indoor tanning than "tanning salon"; 77% versus 45% of tweets captured by these search terms were by individuals who engaged in indoor tanning, respectively. Extrapolating to the full data set of 4,691 tweets, findings suggest that an average of 468 individuals who engage in indoor tanning can be identified by their tweets per day. The majority of tweets were from tanners and included reports of especially risky habits (e.g., burning, falling asleep). Twitter provides opportunity to identify indoor tanners and examine conversations about indoor tanning.

RESUMO

Introduction: Social media have changed the landscape of health communication for nonprofit organizations (NPOs). Yet, adoption and use of social media lag among NPOs in rural Appalachia due largely to limited infrastructure development. Methods: Semi-structured phone interviews were conducted in January-March 2018 with 21 NPO representatives in an 8-county region of rural Appalachian Tennessee. NPO representatives were asked questions pertaining to social media use and message content, effective communication strategies, and best practices in social media use. Transcripts were analyzed in April-May 2018 using thematic analysis. Results: The majority of NPOs had a Facebook page and recognized its promise as a communication tool. However, due to resource constraints, most NPOs used social media as a secondary communication strategy to complement traditional approaches. In terms of messaging, NPOs used social media primarily to share information and solicit donations or volunteers. Representatives identified several obstacles to social media use among NPOs in the region. These included limited organizational resources, community infrastructure, and household resources. Implications: Social media are inexpensive communication tools that NPOs in rural Appalachia can use to expand their digital footprint into hard-to-reach populations. Therefore, eliminating the digital divide across the U.S. is an important step toward enhancing rural NPOs' capacity to serve their communities well. Opportunities for NPO staff to access low-cost professional development and training in the use of social media, specifically for social marketing purposes, are also essential.

RESUMO

BACKGROUND: Cough is common in patients with lung cancer, and current antitussive treatments are suboptimal. There are little published data describing cough in patients with lung cancer or work assessing clinical associations. The aim of this study is to fill that gap. METHODS: This was a longitudinal prospective observational single-cohort study over 60 days. Patients were assessed through self-reported validated scales and, in a subsample, ambulatory cough monitoring at study entry (day 0), day 30, and day 60. RESULTS: At study entry, 177 patients were included and 153 provided data at day 60. The median duration of cough was 52 weeks (interquartile range, 8.5-260). Cough was described as severe enough to warrant treatment in 62% of the patients. Depending on the scale used, performance status was associated with both cough severity and cough impact (P < .001) at study entry, whereas higher cough severity at study entry was associated with female sex (P = .02), asthma (P = .035), and reflux disease (P < .001). Cough impact at study entry was additionally associated with experiencing nausea (P = .018). Cancer characteristics (ie, cancer stage, histology) were not associated with cough severity nor cough impact; neither was smoking or COPD. CONCLUSIONS: This is the first study to describe characteristics of cough in patients with lung cancer and to identify clinical associations that may be relevant for its treatment. Our data suggest that cough is a frequent and distressing symptom and an unmet clinical need. Its association with gastrointestinal symptoms in this study may improve our understanding of pathophysiology and therapeutic options for cough occurring in patients with lung cancer.

RESUMO

The oomycete pathogens Phytophthora infestans and P. capsici cause significant crop losses world-wide, threatening food security. In each case, pathogenicity factors, called RXLR effectors, contribute to virulence. Some RXLRs are perceived by resistance proteins to trigger host immunity, but our understanding of the demographic processes and adaptive evolution of pathogen virulence remains poor. Here, we describe PenSeq, a highly efficient enrichment sequencing approach for genes encoding pathogenicity determinants which, as shown for the infamous potato blight pathogen Phytophthora infestans, make up < 1% of the entire genome. PenSeq facilitates the characterization of allelic diversity in pathogen effectors, enabling evolutionary and population genomic analyses of Phytophthora species. Furthermore, PenSeq enables the massively parallel identification of presence/absence variations and sequence polymorphisms in key pathogen genes, which is a prerequisite for the efficient deployment of host resistance genes. PenSeq represents a cost-effective alternative to whole-genome sequencing and addresses crucial limitations of current plant pathogen population studies, which are often based on selectively neutral markers and consequently have limited utility in the analysis of adaptive evolution. The approach can be adapted to diverse microbes and pathogens.

RESUMO

INTRODUCTION: The field of implementation science provides the variables adoption and reach, which can be used to evaluate aspects to access, a primary incitement for integrated care. This study compared two integrated models: In Year 1, behavioral health consultants worked collaboratively with pediatricians to provide brief on-the-spot consultations to patients with behavioral concerns, and in Year 2, a structured, evidence-based treatment (EBT), the Family Check-Up, was developed to be delivered in conjunction with the existing collaborative model. METHOD: A chart review revealed the number of children who (a) attended a 4- to 5-year-old well-visit, (B) were screened, (c) were identified as having behavior problems, (d) were referred, and (e) accessed the services. Outcomes were calculated as percentages of children with behavioral concerns who were referred to (adoption) and received (reach) the services in each year. RESULTS: Key findings were that (a) physician referrals increased when an EBT was added, but (b) patients had better first-session contact with the brief approach than the EBT, which few patients completed. DISCUSSION: Results underscore the utility of measuring adoption and reach as partial indicators of access to services. These are accessible variables, collected in every practice that can be measured routinely in the context of quality improvement and, ideally, reported in studies as a way to disseminate knowledge about how to build behavioral health technology into primary care. Future research should strive for more rigor in measuring adoption and reach, and consider including a number of other implementation outcomes.

RESUMO

Numerous genes that determine the outcome of plant-pathogen interactions are currently being discovered and include, for example, immune receptors, susceptibility factors and pathogen effectors and their host targets. Target enrichment sequencing provides a means to preferentially resequence these genes of interest without the need to first generate a genotype-specific genome assembly. The Basic Local Alignment Search Tool (BLAST), in combination with the here developed BLASTmap, can be used to design probes that specifically target such gene(s), either by using the target species or the closest related genus as a reference. BLAST is a ubiquitous tool in biological sequence analysis and a multitude of programs are available for the visualization of BLAST alignments. However, there are currently no dedicated programs for visual comparison of large-scale BLAST output attributes such as bit score. The need to quickly and efficiently compare many thousands of BLAST results led to the development of BLASTmap, an interactive web application created using the Shiny R package, customized for clustering and viewing BLAST results as an interactive heat map. Here we show an example of how BLASTmap was successfully applied to analyze custom DNA/RNA probe sequences and to visually determine that four probes are sufficient for the specific yet inclusive enrichment of the potato R2 disease resistance gene family.
