    Previous research has estimated that 20–30% of individuals with opioid use disorder (OUD) have a history of both suicide attempt and unintentional opioid overdose. In 2018, more than 1.9 million adults 18 years and older had an OUD; while 1.4 million adults attempted suicide that same year (SAMHSA, 2019). The key to understanding this relationship is examining behaviors that precede these potentially fatal behaviors. One such precursory behavior is self-injury. Self-injurious behaviors (SIB) are one of the most important risk factors for future suicide (Cavanagh et al.,2003). This study has three primary objectives. The first is to conduct a systematic literature review to better understand the relationship between SIB, overdose and/or suicidal behaviors (i.e. suicidal ideation, suicide planning, or attempt) among people with OUD. Results from the systematic review were used to inform the second and third aims of this study. The second aim was to evaluate the feasibility of a standardized screen for suicide and overdose among patients receiving addiction treatment. The combined results of the systematic review and mPSS helped shape the final aim of this study. A cross-sectional study conducted in a subset of subjects who screened positive on the mPSS were used to assess clinical characteristics. Participants were categorized into three mutually exclusive groups: 1) unintentional overdose(s) (OD), 2) suicidal ideation or suicide attempt(s) (SI/SA), and 3) suicidal ideation or suicide attempt and unintentional overdose (SI/SA/OD). Multinomial logistic regression models were used to determine whether adverse childhood experiences (ACE), self-injurious behaviors, substance use history, overdose history, and past year stressful life events were differentially associated with history of OD/SI/SA. All subjects categorized as having an unintentional OD only, reported having ever used cocaine, while only 72% of SI/SA subjects had ever used cocaine (p=0.02). Subjects in the unintentional OD group were more likely to have used heroin in the 24-hours preceding their most recent overdose (92.3%) compared to SI/SA (30.7%) and SI/SA/OD (75.0 %). In the multivariable model subjects with history of SI/SA had higher ACE scores and higher mean episodes of SIB than either of the other two participant groups. Findings from this study support simultaneously screening for suicide and overdose in OUD inpatient treatment settings. Among patients who screen positive for all three outcomes, SI/SA/OD, there appears to be greater clinical severity. More thorough evaluation of drugs involved in overdose and history of self-injury may help distinguish future risk and better inform treatment planning. Collectively this information has implications for resource needs, treatment, and prevention. However, additional research is needed to determine whether screening improves provision of services and reduces self-injurious behavior

    Detection of Fused Genes in Eukaryotic Genomes using Gene deFuser: Analysis of the Tetrahymena thermophila genome

    <p>Abstract</p> <p>Background</p> <p>Fused genes are important sources of data for studies of evolution and protein function. To date no service has been made available online to aid in the large-scale identification of fused genes in sequenced genomes. We have developed a program, Gene deFuser, that analyzes uploaded protein sequence files for characteristics of gene fusion events and presents the results in a convenient web interface.</p> <p>Results</p> <p>To test the ability of this software to detect fusions on a genome-wide scale, we analyzed the 24,725 gene models predicted for the ciliated protozoan <it>Tetrahymena thermophila</it>. Gene deFuser detected members of eight of the nine families of gene fusions known or predicted in this species and identified nineteen new families of fused genes, each containing between one and twelve members. In addition to these genuine fusions, Gene deFuser also detected a particular type of gene misannotation, in which two independent genes were predicted as a single transcript by gene annotation tools. Twenty-nine of the artifacts detected by Gene deFuser in the initial annotation have been corrected in subsequent versions, with a total of 25 annotation artifacts (about 1/3 of the total fusions identified) remaining in the most recent annotation.</p> <p>Conclusions</p> <p>The newly identified <it>Tetrahymena </it>fusions belong to classes of genes involved in processes such as phospholipid synthesis, nuclear export, and surface antigen generation. These results highlight the potential of Gene deFuser to reveal a large number of novel fused genes in evolutionarily isolated organisms. Gene deFuser may also prove useful as an ancillary tool for detecting fusion artifacts during gene model annotation.</p

    Establishing Peer Recovery Support Services to Address the Central Appalachian Opioid Epidemic: The West Virginia Peers Enhancing Education, Recovery, and Survival (WV PEERS) Pilot Program

    Introduction: Central Appalachia has been disproportionately affected by the opioid epidemic and overdose fatalities. We developed West Virginia Peers Enhancing Education, Recovery, and Survival (WV PEERS), a program based on peer recovery support, to engage individuals using opioids and link them with a range of services. Methods: Community partners providing services to individuals with opioid use disorder (OUD) were identified and collaborations were formalized using a standardized memorandum of understanding. The program was structured to offer ongoing peer recovery support specialist (PRSS) services, not just a one-time referral. A website and cards describing the WV PEERS program were developed and disseminated via community partners and community education sessions. Results: Overall, 1456 encounters with individuals with OUD (mean= 2 encounters per individual) occurred in a variety of community settings over 8 months. The majority of referrals were from harm reduction programs. Overall, 63.9% (n=931) of individuals served by WV PEERS accessed services for substance use disorders and/or mental health problems. Over half (52.3%; n = 487) of individuals entered substance use and/or mental health treatment, and nearly a third (30.4%; n = 283) remained in treatment over six months. Implications: Using the WV PEERS model, PRSSs effectively engaged and linked individuals with OUD to mental health and substance use treatment in rural central Appalachia. Future research is needed to determine whether these services reduce the risk of overdose mortality

    Experimental determination of translational start sites resolves uncertainties in genomic open reading frame predictions – application to Mycobacterium tuberculosis

    Get PDF
    Correct identification of translational start sites is important for understanding protein function and transcriptional regulation. The annotated translational start sites contained in genome databases are often predicted using bioinformatics and are rarely verified experimentally, and so are not all accurate. Therefore, we devised a simple approach for determining translational start sites using a combination of epitope tagging and frameshift mutagenesis. This assay was used to determine the start sites of three Mycobacterium tuberculosis proteins: LexA, SigC and Rv1955. We were able to show that proteins may begin before or after the predicted site. We also found that a small, non-annotated open reading frame upstream of Rv1955 was expressed as a protein, which we have designated Rv1954A. This approach is readily applicable to any bacterial species for which plasmid transformation can be achieved

    LSST: from Science Drivers to Reference Design and Anticipated Data Products

    (Abridged) We describe here the most ambitious survey currently planned in the optical, the Large Synoptic Survey Telescope (LSST). A vast array of science will be enabled by a single wide-deep-fast sky survey, and LSST will have unique survey capability in the faint time domain. The LSST design is driven by four main science themes: probing dark energy and dark matter, taking an inventory of the Solar System, exploring the transient optical sky, and mapping the Milky Way. LSST will be a wide-field ground-based system sited at Cerro Pach\'{o}n in northern Chile. The telescope will have an 8.4 m (6.5 m effective) primary mirror, a 9.6 deg2^2 field of view, and a 3.2 Gigapixel camera. The standard observing sequence will consist of pairs of 15-second exposures in a given field, with two such visits in each pointing in a given night. With these repeats, the LSST system is capable of imaging about 10,000 square degrees of sky in a single filter in three nights. The typical 5σ\sigma point-source depth in a single visit in rr will be ∌24.5\sim 24.5 (AB). The project is in the construction phase and will begin regular survey operations by 2022. The survey area will be contained within 30,000 deg2^2 with ÎŽ<+34.5∘\delta<+34.5^\circ, and will be imaged multiple times in six bands, ugrizyugrizy, covering the wavelength range 320--1050 nm. About 90\% of the observing time will be devoted to a deep-wide-fast survey mode which will uniformly observe a 18,000 deg2^2 region about 800 times (summed over all six bands) during the anticipated 10 years of operations, and yield a coadded map to r∌27.5r\sim27.5. The remaining 10\% of the observing time will be allocated to projects such as a Very Deep and Fast time domain survey. The goal is to make LSST data products, including a relational database of about 32 trillion observations of 40 billion objects, available to the public and scientists around the world.Comment: 57 pages, 32 color figures, version with high-resolution figures available from https://www.lsst.org/overvie

    Clackamas County 2011-2012 Diversity Assessment (Phase I)

    Get PDF
    Clackamas County conducted its first diversity assessment in 2001. Since then, the County has taken significant steps to promote diversity within the organization, including the creation of a Diversity and Inclusion Manager position. This 2011-2012 assessment is the first phase of the County’s attempt to evaluate its current diversity climate and the effectiveness of its diversity efforts. Results in this report are based on data collected from February to April 2012. In July 2012, after the data collection of this phase I assessment process, the Clackamas County Board of County Commissioners adopted a resolution titled ”Valuing Diversity in Clackamas County.” The resolution affirmed the County’s commitment to value and promote diversity, and identified some concrete future actions. The adoption of the resolution influenced the County’s overall diversity climate after July 2012. It should be noted that although efforts have been made to incorporate the County’s resolution and its potential implications into this report, the diversity climate mainly represents the period prior to the adoption of the resolution

    A Scoping Review of Suicide Prevention Training Programs for Pharmacists and Student Pharmacists

    No full text
    Objective. This scoping review updates a 2018 review of suicide prevention training programs for community and student pharmacists. Five scholarly databases were searched for articles published between January 2018 and December 2020. Articles were excluded if they did not describe an educational or training program for pharmacists or student pharmacists, did not explicitly include suicide, focused solely on attitudes, or did not provide sufficient detail to evaluate program content. The quality of each study was examined using a quality assessment tool.Findings. Seven studies met inclusion criteria. Most trainings (86%) were delivered live with interactive or role play scenarios to promote verbal and behavioral skill practice. About half (57%) assessed changes in knowledge, and fewer programs (29%) assessed changes in communication. All assessed participants\u27 ability to identify suicide warning signs and included referral resources. Six studies were assessed for quality, of which 67% had a rating of good and 33% were rated as fair.Summary. Given the increase in suicide rates nationally, it is likely that pharmacists will encounter a patient in need of suicide prevention services. Since 2018, seven new suicide prevention training programs for community and student pharmacists have been reported, which demonstrates growing interest in suicide prevention training in the pharmacy profession. When integrated in Doctor of Pharmacy (PharmD) curricula, trainings may help prepare the pharmacy workforce for encounters with patients in crisis. The impact of training on self-efficacy and communication skills warrants additional attention. Variation between programs should be evaluated to understand which instructional methods best prepare pharmacy professionals to engage in suicide prevention

    Objective To determine whether a brief suicide prevention training with an interactive video case (Pharm-SAVES) improves student pharmacists’ suicide prevention knowledge and self-efficacy. Methods Student pharmacists (N = 146) from 2 United States universities completed the 75-minute Pharm-SAVES training in September 2021. Suicide prevention knowledge and self-efficacy were measured via an online pre-test and post-test, and a post-test interactive video case assessed self-efficacy to engage in SAVES steps (recognize Signs, Ask about suicide, Validate feelings, Expedite a National Suicide Prevention Lifeline [NSPL] referral, and Set a follow-up reminder). Paired samples t tests compared pre-test and post-test scores (alpha = 0.05). Three months later, students indicated if they had used Pharm-SAVES in practice. Results Mean knowledge and self-efficacy significantly improved from pre-test to post-test. The interactive video case assessment revealed that students were least confident asking about suicide, moderately confident referring to or calling the NSPL on behalf of patients, and most confident following up with patients. Three months later, 17 (11.6%) students reported that they had recognized someone with suicide warning signs (S in SAVES). Among them, 9 (52.9%) reported asking the person with warning signs if they were considering suicide (A in SAVES), 13 (76.5%) validated feelings (V in SAVES), 3 (9.4%) called the NSPL for the patient, and 6 (35.3%) referred to the NSPL (E in SAVES). Conclusion Pharm-SAVES increased student pharmacists’ suicide prevention knowledge and self-efficacy. Within 3 months, more than 10% had used Pharm-SAVES skills with at-risk individuals. All Pharm-SAVES content is now online and available for asynchronous or synchronous instruction
