Breaking the Chain: Evaluating the Links Between Opioid Use Disorder, Overdose, and Suicide
Previous research has estimated that 20â30% 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 â application to Mycobacterium tuberculosis
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 deg 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 5
point-source depth in a single visit in will be (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 deg with
, and will be imaged multiple times in six bands, ,
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 deg region about 800 times (summed over all six bands) during the
anticipated 10 years of operations, and yield a coadded map to . 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

Escalating costs of self-injury mortality in the 21st century United States: an interstate observational study
Background
Estimating the economic costs of self-injury mortality (SIM) can inform health planning and clinical and public health interventions, serve as a basis for their evaluation, and provide the foundation for broadly disseminating evidence-based policies and practices. SIM is operationalized as a composite of all registered suicides at any age, and 80% of drug overdose (intoxication) deaths medicolegally classified as âaccidents,â and 90% of corresponding undetermined (intent) deaths in the age group 15 years and older. It is the long-term practice of the United States (US) Centers for Disease Control and Prevention (CDC) to subsume poisoning (drug and nondrug) deaths under the injury rubric. This study aimed to estimate magnitude and change in SIM and suicide costs in 2019 dollars for the United States (US), including the 50 states and the District of Columbia.
Methods
Cost estimates were generated from underlying cause-of-death data for 1999/2000 and 2018/2019 from the US Centers for Disease Control and Preventionâs (CDCâs) Wide-ranging ONline Data for Epidemiologic Research (WONDER). Estimation utilized the updated version of Medical and Work Loss Cost Estimation Methods for CDCâs Web-based Injury Statistics Query and Reporting System (WISQARS). Exposures were medical expenditures, lost work productivity, and future quality of life loss. Main outcome measures were disaggregated, annual-averaged total and per capita costs of SIM and suicide for the nation and states in 1999/2000 and 2018/2019.
Results
40,834 annual-averaged self-injury deaths in 1999/2000 and 101,325 in 2018/2019 were identified. Estimated national costs of SIM rose by 143% from 1.12 trillion. Ratios of quality of life and work losses to medical spending in 2019 US dollars in 2018/2019 were 1,476 and 526, respectively, versus 1,419 and 526 in 1999/2000. Total national suicide costs increased 58%âfrom 502.7Â billion. National per capita costs of SIM doubled from 3,413 over the observation period; costs of the suicide component rose from 1,534. States in the top quintile for per capita SIM, those whose cost increases exceeded 152%, concentrated in the Great Lakes, Southeast, Mideast and New England. States in the bottom quintile, those with per capita cost increases below 70%, were located in the Far West, Southwest, Plains, and Rocky Mountain regions. West Virginia exhibited the largest increase at 263% and Nevada the smallest at 22%. Percentage per capita cost increases for suicide were smaller than for SIM. Only the Far West, Southwest and Mideast were not represented in the top quintile, which comprised states with increases of 50% or greater. The bottom quintile comprised states with per capita suicide cost increases below 24%. Regions represented were the Far West, Southeast, Mideast and New England. North Dakota and Nevada occupied the extremes on the cost change continuum at 75% and ââ1%, respectively.
Conclusion
The scale and surge in the economic costs of SIM to society are large. Federal and state prevention and intervention programs should be financed with a clear understanding of the total costsâfiscal, social, and personalâincurred by deaths due to self-injurious behaviors
Clackamas County 2011-2012 Diversity Assessment (Phase I)
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 Countyâs 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 âValuing Diversity in Clackamas County.â The resolution affirmed the Countyâs commitment to value and promote diversity, and identified some concrete future actions. The adoption of the resolution influenced the Countyâs overall diversity climate after July 2012. It should be noted that although efforts have been made to incorporate the Countyâs 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
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
Impact of a Brief Suicide Prevention Training with an Interactive Video Case Assessment on Student Pharmacist Outcomes
Objective To determine whether a brief suicide prevention training with an interactive video case (Pharm-SAVES) improves student pharmacistsâ 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 pharmacistsâ 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
