Knowledge of medications for opioid use disorder and associated stigma among primary care professionals.

BACKGROUND: Medications for opioid use disorder (MOUD) are the gold standard. However, significant barriers limit their use in the primary care setting, including limited knowledge of the medications and stigmatizing attitudes. In this study, we assess knowledge levels among primary care-aligned professionals (PCPs) currently in practice, and whether knowledge of MOUD is associated with stigma and treatment attitudes. PARTICIPANTS AND METHODS: Using rosters from the state of Ohio licensing boards, we surveyed 403 physicians, nurse practitioners, and physician associates in 2022, on the mechanism of different MOUD, as well as stigma and treatment attitudes. To assess MOUD knowledge, we employed descriptive and bivariate statistics. We fit four linear regression models, which controlled for empathy towards patients with OUD and provider demographics to assess the relationship between MOUD knowledge and four endpoints: stigma, perceived controllability of opioid use, perceived vulnerability to opioid use disorder, and support for abstinence-only treatment. RESULTS: 43% of participants correctly identified the mechanism of all 3 medications whereas 13% of participants did not identify the mechanism of any MOUD correctly. MOUD knowledge was higher among physicians as compared to nurse practitioners and physician associates. Lower MOUD knowledge was associated with more negative attitudes towards patients with OUD and MOUD treatment. CONCLUSION: Expanding access to MOUD treatment requires a trained and willing health-care professional (HCP) workforce. Our findings highlight considerable variation in clinician knowledge of MOUD and suggest that knowledge levels are also related to negative attitudes towards patients with OUD and MOUD. Training interventions that increase knowledge, as well as focus on stigma reduction, are critical for reducing the longstanding treatment gap for opioid use disorder.

A rapid review protocol of physiotherapy and occupational therapy telerehabilitation to inform ethical and equity concerns.

Background: Telerehabilitation (TR) has emerged as a feasible and promising approach for delivering rehabilitation services remotely, utilizing technology to bridge the gap between healthcare providers and patients. As new modalities of virtual care and health technologies continue to emerge, it is crucial to stay informed about the growing landscape of virtual care to ensure that telehealth service delivery is ethical and equitable, and improves the quality of services and patient outcomes. Objective: The primary objective of this article is to present the protocol of a rapid review to examine the equity-related aspects surrounding the implementation of TR. This includes a comprehensive analysis of the ethical dimensions and fairness concerns linked to this practice. Methods: A rapid review protocol was developed in accordance with Cochrane Rapid Reviews Methods Guidance. Medline and EMBASE databases were searched between January 2010 and March 2023. Study selection and data extraction will be conducted in two phases (Phase I) by two independent reviewers and subsequently (Phase II) by a single reviewer. Our study will utilize the PROGRESS-Plus and Equitable virtual rehabilitation in the metaverse era framework to identify dimensions where potential inequities may exist within TR interventions. Results: This rapid review is anticipated to enhance our knowledge of TR in the fields of physiotherapy and occupational therapy, with a specific focus on its influence on ethical and equitable practices and providing a foundation for informed decision-making and improved patient care. Conclusion: This rapid review will contribute to the advancement of our understanding of TR within physiotherapy and occupational therapy. Through synthesizing existing evidence, this study not only addresses current gaps in knowledge but also offers valuable insights for future research and clinical practice in TR services.

Updated Risk Score Algorithms for Acute HIV Infection Detection at a Sexually Transmitted Infections Clinic in Lilongwe, Malawi.

BACKGROUND: Detection of acute (pre-seroconversion) HIV infection (AHI), the phase of highest transmission risk, requires resource-intensive RNA- or antigen-based detection methods that can be infeasible for routine use. Risk score algorithms can improve the efficiency of AHI detection by identifying persons at highest risk of AHI for prioritized RNA/antigen testing, but prior algorithms have not considered geospatial information, potential differences by sex, or current antibody testing paradigms. METHODS: We used elastic net models to develop sex-stratified risk score algorithms in a case-control study of persons (136 with AHI, 250 without HIV) attending a sexually transmitted infections (STI) clinic in Lilongwe, Malawi from 2015 to 2019. We designed algorithms for varying clinical contexts according to three levels of data availability: 1) routine demographic and clinical information, 2) behavioral and occupational data obtainable through patient interview, and 3) geospatial variables requiring external datasets or field data collection. We calculated sensitivity, specificity, and area under the receiver operating characteristic curve (AUC) to assess model performance and developed a web application to support implementation. RESULTS: The highest-performing AHI risk score algorithm for men (AUC=0.74) contained five variables (condom use, body aches, fever, rash, genital sores/ulcers) from the first two levels of data availability. The highest-performing algorithm for women (AUC=0.81) contained fifteen variables from all three levels of data availability. A risk score cut-point of 0.26 had an AHI detection sensitivity of 93% and specificity of 27% for males, and a cut-point of 0.15 had 97% sensitivity and 44% specificity for females. Additional models are available in the web application. CONCLUSION: Risk score algorithms can facilitate efficient AHI detection in STI clinic settings, creating opportunities for HIV transmission prevention interventions during this critical period of elevated transmission risk.

The War on Drugs, Racialized Capitalism, and Health Care Utilization Among White People Who Use Drugs in 22 Rural Appalachian Counties.

Objectives. To analyze War on Drugs encounters and their relationships to health care utilization among White people who use drugs (PWUD) in 22 Appalachian rural counties in Kentucky, West Virginia, Ohio, and North Carolina. Methods. We recruited White PWUD using chain referral sampling in 2018 to 2020. Surveys asked about criminal-legal encounters, unmet health care needs, and other covariates. We used generalized estimating equations to regress unmet need on criminal-legal encounters in multivariable models. Results. In this sample (n = 957), rates of stop and search, arrest, incarceration, and community supervision were high (44.0%, 26.8%, 36.3%, and 31.1%, respectively), as was unmet need (68.5%). Criminal-legal encounters were unrelated to unmet need (stops: adjusted prevalence ratio [APR] = 1.13; 95% confidence interval [CI] = 0.97, 1.32; arrest: APR = 0.95; 95% CI = 0.78, 1.15; incarceration: APR = 1.01; 95% CI = 0.89, 1.14; community supervision: APR = 0.99; 95% CI = 0.90, 1.09). Conclusions. Contrasting with findings from predominantly Black urban areas, criminal-legal encounters and unmet need were unrelated among White Appalachian PWUD. Research should explore whether and under what conditions White supremacy's benefits might buffer adverse impacts of the War on Drugs in Appalachia.

An Automated Text Messaging Intervention to Reduce Substance Use Self-Stigma (Project RESTART): Protocol for a Feasibility and Acceptability Pilot Study.

BACKGROUND: Stigma is a barrier to treatment and harm reduction seeking in people who use drugs. Most stigma reduction interventions offer psychotherapy or psychoeducation in group-based clinical settings, failing to reach people who are not in treatment. SMS text messaging is an effective and acceptable modality for delivering health information to people who use drugs and may be a suitable conduit for providing information and advice to understand and cope with stigma. OBJECTIVE: This paper presents the protocol for a study that aims to determine the feasibility, acceptability, and preliminary effectiveness of a 4-week automated SMS text message intervention to increase stigma resistance and reduce self-stigma in people who use drugs. METHODS: We designed a novel automated SMS text message intervention to address the four personal-level constructs of stigma resistance: (1) not believing stigma and catching and challenging stigmatizing thoughts, (2) empowering oneself through learning about substance use and one's recovery, (3) maintaining one's recovery and proving stigma wrong, and (4) developing a meaningful identity and purpose apart from one's substance use. Theory-based messages were developed and pilot-tested in qualitative elicitation interviews with 22 people who use drugs, resulting in a library of 56 messages. In a single-group, within-subjects, community-based pilot trial, we will enroll 30 participants in the Resisting Stigma and Revaluating Your Thoughts (RESTART) intervention. Participants will receive 2 daily SMS text messages for 4 weeks. Implementation feasibility will be assessed through recruitment, enrollment, retention, and message delivery statistics. User feasibility and acceptability will be assessed at follow-up using 23 survey items informed by the Theoretical Framework of Acceptability. Primary effectiveness outcomes are changes in self-stigma (Substance Abuse Self-Stigma Scale) and stigma resistance (Stigma Resistance Scale) from baseline to follow-up measured via a self-administered survey. Secondary outcomes are changes in hope (Adult Dispositional Hope Scale) and self-esteem (Rosenberg Self-Esteem Scale). Feasibility and acceptability will be assessed with descriptive statistics; effectiveness outcomes will be assessed with paired 2-tailed t tests, and group differences will be explored using ANOVA. Overall, 12 participants will also be selected to complete acceptability interviews. RESULTS: This pilot study was funded by the National Institute on Drug Abuse in April 2023 and received regulatory approval in January 2024 by the University of North Carolina-Chapel Hill Institutional Review Board. Recruitment and enrollment began in March 2024. Follow-up visits are expected to conclude by May 2024. Results will be disseminated in relevant peer-reviewed journals. CONCLUSIONS: To the best of our knowledge, this is the first study to address substance use stigma via a self-help SMS text messaging program. Results will add to the nascent literature on stigma reduction in people who use drugs. This protocol may interest researchers who are considering text messaging to address psychosocial needs in hard-to-reach populations.

Behavioral and Health Outcome Differences by Heroin or Methamphetamine Preference Among People in Rural US Communities Who Use Both Substances.

Background: The United States' (US) opioid overdose epidemic has evolved into a combined stimulant/opioid epidemic, a pattern driven in part by mitigating opioid overdose risk, variable substance availability, and personal preferences. This study aimed to investigate the association between self-reported substance preference (heroin or methamphetamine) and behavioral/health outcomes among individuals who used both heroin and methamphetamine in the rural US. Methods: The Rural Opioid Initiative is a consortium of 8 research cohorts from 10 states and 65 rural counties that recruited individuals reporting past 30-day injection of any substance or opioid substance use by any route from 1/2018 to 3/2020. Analyses were restricted to participants ⩾18 years, who self-reported either heroin or methamphetamine as their preferred substance and past 30-day use of both heroin and methamphetamine. We examined cross-sectional associations between preferred substance (heroin versus methamphetamine) and behavioral and health outcomes using random effects meta-analysis with adjusted regression models. Results: Among 1239 participants, 61% (n = 752) reported heroin as their preferred substance. Adjusting for age, sex, and race/ethnicity, methamphetamine preference was associated with lower prevalence ratios for current naloxone possession (adjusted prevalence ratio [aPR] = 0.68; 95% Confidence Interval [95% CI] = 0.59-0.78; P-value ⩽ .001), of ever being told they had the hepatitis C virus (HCV; aPR = 0.72; 95% CI: 0.61-0.85; P-value ⩽ .001) and a personal history of overdose (aPR = 0.81; 95% CI = 0.73-0.90; P-value ⩽ .001). Conclusion: In our study analyzing associations between preferred substance and various behavioral and health outcomes amongst people who use both heroin and methamphetamine, a majority of participants preferred heroin. Methamphetamine preference was associated with lower prevalence of naloxone possession, ever being told they had HCV, and prior history of an overdose. This study underscores the need for targeted harm reduction services for people who prefer methamphetamine in rural areas.

Feasibility and Acceptability of a Prospective Syphilis Sexual Network Study for Sexual Minority Men.

BACKGROUND: In preparation for a prospective syphilis network study of sexual minority men, we conducted a mixed-methods formative study with the following objectives: a) assess acceptability of respondent driven sampling (RDS), b) assess acceptability of study procedures, c) social network seed selection, and d) pilot an ecological momentary assessment (EMA) study to assess social networking, sexual and substance use behavior. METHODS: We conducted in-depth interviews with eight providers serving sexual minority men and five focus group discussions with 34 sexual minority men, prioritizing four target populations: young Black sexual minority men, 2) on PrEP, 3) living with HIV, 4) not engaged in care. The 4-week EMA pilot was conducted with 40 sexual minority men. EMA survey responses were analyzed to evaluate how different compensation levels influenced response rates. Brief exit surveys were used to assess EMA app acceptability. RESULTS: Primary themes identified through qualitative data collection: 1) importance of developing trust and maintaining confidentiality during proposed recruitment activities, 2) importance of compensating participants appropriately for study activities, and 3) cultural considerations for increasing visibility and participation of young Black sexual minority men. All EMA participants reported being "completely comfortable" reporting sexual behavior through the app. Most (78%) preferred the app to in-person interviews. Several participants identified technical issues with the app, including not receiving push notifications and spontaneous closure. CONCLUSIONS: This mixed-methods formative study allowed for adjustments to and tailoring of the planned network study, including recruitment protocols, compensation type and amount, and EMA survey wording and response items.

A Brief Alcohol Intervention (BAI) to reduce alcohol use and improve PrEP outcomes among men who have sex with men in Vietnam: study protocol for a randomized controlled trial.

BACKGROUND: In Vietnam and other global settings, men who have sex with men (MSM) have become the population at greatest risk of HIV infection. Although HIV pre-exposure prophylaxis (PrEP) has been implemented as a prevention strategy, PrEP outcomes may be affected by low persistence and adherence among MSM with unhealthy alcohol use. MSM have a high prevalence of unhealthy alcohol use in Vietnam, which may affect PrEP outcomes. METHODS: Design: We will conduct a two-arm hybrid type 1 effectiveness-implementation randomized controlled trial of a brief alcohol intervention (BAI) compared to the standard of care (SOC) at the Sexual Health Promotion (SHP) clinic Hanoi, Vietnam. PARTICIPANTS: Sexually active MSM (n=564) who are newly initiating PrEP or re-initiating PrEP and have unhealthy alcohol use will be recruited and randomized 1:1 to the SOC or BAI arm. A subgroup of participants (n=20) in each arm will be selected for longitudinal qualitative interviews; an additional subset (n=48) in the BAI arm will complete brief quantitative and qualitative interviews after completion of the BAI to assess the acceptability of the intervention. Additional implementation outcomes will be assessed through interviews with clinic staff and stakeholders (n=35). INTERVENTION: Study participants in both arms will receive standard care for PrEP clients. In the BAI arm, each participant will receive two face-to-face intervention sessions and two brief booster phone sessions, based on cognitive behavioral therapy and delivered in motivational interviewing informed style, to address their unhealthy alcohol use. OUTCOMES: Effectiveness (PrEP and alcohol use) and cost-effectiveness outcomes will be compared between the two arms. Intervention implementation outcomes (acceptability, feasibility, adoption) will be assessed among MSM participants, clinic staff, and stakeholders. DISCUSSION: This proposed trial will assess an alcohol intervention for MSM with unhealthy alcohol use who initiate or re-initiate PrEP, while simultaneously preparing for subsequent implementation. The study will measure the effectiveness of the BAI for increasing PrEP persistence through reducing unhealthy alcohol use in a setting where excessive alcohol consumption is a normative behavior. If effective, implementation-focused results will inform future scale-up of the BAI in similar settings. TRIAL REGISTRATION: NCT06094634 on clinicaltrials.gov. Registered 16 October 2023.

Developing Leaders in Surgical Residency: A Curriculum for Success.

OBJECTIVE: As surgical residents continue in their training, they are expected to not only take part in more complicated procedures, but to also serve as leaders in their respective care teams. While surgical skills are intensively taught in surgical residency programs, leadership is often learned informally, to the detriment of residents. Our curriculum was developed and implemented to provide foundational knowledge for surgical residents as they take on senior roles so that they may successfully act as leaders. This educational workshop was effective and efficient and can be applied at other residency programs that seek to improve the leadership skills of their residents. DESIGN: Implementation of a 3-day program focused on leadership, surgical skills, and career development to provide rising PGY-4 surgical residents with the abilities necessary for successful training. SETTING: This program was implemented at the University of Minnesota General Surgery residency program. PARTICIPANTS: Rising PGY-4 general surgery residents. RESULTS: The program consisted of a 3-day workshop which all rising PGY-4 residents participating in before transitioning into their respective roles. The program was led by the general surgery faculty. CONCLUSIONS: Curricula focused on developing leadership skills in residents can be effectively applied in a time-efficient manner that can benefit the residents as they move into official leadership roles on the care team.

Enabled to Stand: A Single-subject Research Design Study Exploring Pediatric Power Wheelchair Standing Device Use.

PURPOSE: To investigate the influence of powered wheelchair standing device (PWSD) use on changes in activity/participation in children with neurodevelopmental conditions. METHODS: A mixed methods A-B-A single-subject research design was replicated with participants. The target behavior was parental perceptions of changes in children's performance of activity/participation goals measured via the Canadian Occupational Performance Measure (COPM). Secondary outcome measures included the COPM with children, an interview, and a 3-measure implementation survey. COPM data related to the target behavior were analyzed using the split-middle celeration line method. RESULTS: Four child-parent dyads participated in the study. All participants achieved statistically and clinically significant increases in COPM performance ratings for the 5 parent-identified activity/participation goals. CONCLUSIONS: For the participant dyads in this study, use of the PWSD appeared to positively influence parental perceptions of improvements in their child's performance of activity/participation goals.

Scaling up a brief alcohol intervention to prevent HIV infection in Vietnam: a cluster randomized, implementation trial.

BACKGROUND: Evidence-based interventions (EBIs) often address normative behaviors. If a behavior is also common among clinicians, they may be skeptical about the necessity or effectiveness of an EBI. Alternatively, clinicians' attitudes and behaviors may be misaligned, or they may lack the knowledge and self-efficacy to deliver the EBI. Several EBIs address unhealthy alcohol use, a common and often culturally acceptable behavior. But unhealthy alcohol use may be particularly harmful to people with HIV (PWH). Here, we present an implementation trial using an experiential implementation strategy to address clinicians' knowledge, attitudes, and behaviors. Clinicians receive the experiential intervention before they begin delivering an evidence-based brief alcohol intervention (BAI) to PWH with unhealthy alcohol use. METHODS: Design: In this hybrid type 3 implementation-effectiveness cluster randomized controlled trial, ART clinics (n = 30) will be randomized 1:1 to facilitation, a flexible strategy to address implementation barriers, or facilitation plus the experiential brief alcohol intervention (EBAI). In the EBAI arm, clinicians, irrespective of their alcohol use, will be offered the BAI as experiential learning. EBAI will address clinicians' alcohol-related attitudes and behaviors and increase their knowledge and confidence to deliver the BAI. PARTICIPANTS: ART clinic staff will be enrolled and assessed at pre-BAI training, post-BAI training, 3, 12, and 24 months. All PWH at the ART clinics who screen positive for unhealthy alcohol use will be offered the BAI. A subset of PWH (n = 810) will be enrolled and assessed at baseline, 3, and 12 months. OUTCOMES: We will compare implementation outcomes (acceptability, fidelity, penetration, costs, and sustainability) and effectiveness outcomes (viral suppression and alcohol use) between the two arms. We will assess the impact of site-level characteristics on scaling-up the BAI. We will also evaluate how experiencing the BAI affected clinical staff's alcohol use and clinic-level alcohol expectations in the EBAI arm. DISCUSSION: This trial contributes to implementation science by testing a novel strategy to implement a behavior change intervention in a setting in which clinicians themselves may engage in the behavior. Experiential learning may be useful to address normative and difficult to change lifestyle behaviors that contribute to chronic diseases.

Crowdsourced Partner Services Among Men Who Have Sex With Men Living With HIV: A Pilot Randomized Controlled Trial in China.

BACKGROUND: This study aimed to assess the acceptability, feasibility, and preliminary effectiveness of a crowdsourced HIV partner services (PS) intervention among men who have sex with men living with HIV (MLWH) in China. METHODS: A pilot 2-arm randomized controlled trial was conducted in 3 HIV testing clinics in China. The control arm received conventional HIV PS, whereas the intervention arm received a crowdsourced intervention, including HIV self-testing kits for secondary distribution (HIVST-SD), digital education materials, and assisted PS. The intervention was developed through 2-phase crowdsourcing events including an open call and a Designathon. The primary outcomes were measured by the 3-month follow-up rate (i.e., the proportion of participants who completed the follow-up survey to report HIV PS outcomes 3 months after enrollment) and the frequency of using intervention components (feasibility), index evaluation of intervention components (acceptability), and the proportion of partners getting HIV testing (preliminary effectiveness). RESULTS: The study enrolled 121 newly diagnosed MLWH between July 2021 and May 2022. The 3-month follow-up rates were 93% (75 of 81) and 83% (33 of 40) in the intervention and control arms, respectively. Crowdsourced intervention components demonstrated feasibility, with all indexes using digital educational materials, 23 successfully using HIVST-SD, and 6 employing provider-referral to notify 9 sexual partners. Acceptability was high, with HIVST-SD and digital educational materials rated 4.4 and 4.1 out of 5. The proportion of partners receiving HIV testing was 11% higher in the intervention arm than in the control arm (marginal significance with 95% confidence interval, -2% to 24%; 38% vs. 27%). CONCLUSIONS: The crowdsourced HIV PS intervention was acceptable and feasible, suggesting the potential to facilitate partner HIV testing among Chinese MLWH. Further implementation research is recommended to expand HIV PS among key populations in low- and middle-income countries. CLINICAL TRIAL REGISTRATION ID: NCT04971967 (Protocol ID: 19-0496).

Forecasting Hepatitis C Virus Status for Children in the United States: A Modeling Study.

BACKGROUND: Virtually all cases of hepatitis C virus (HCV) infection in children in the United States occur through vertical transmission, but it is unknown how many children are infected. Cases of maternal HCV infection have increased in the United States, which may increase the number of children vertically infected with HCV. Infection has long-term consequences for a child's health, but treatment options are now available for children ≥3 years old. Reducing HCV infections in adults could decrease HCV infections in children. METHODS: Using a stochastic compartmental model, we forecasted incidence of HCV infections in children in the United States from 2022 through 2027. The model considered vertical transmission to children <13 years old and horizontal transmission among individuals 13-49 years old. We obtained model parameters and initial conditions from the literature and the Centers for Disease Control and Prevention's 2021 Viral Hepatitis Surveillance Report. RESULTS: Model simulations assuming direct-acting antiviral treatment for children forecasted that the number of acutely infected children would decrease slightly and the number of chronically infected children would decrease even more. Alone, treatment and early screening in individuals 13-49 years old reduced the number of forecasted cases in children and, together, these policy interventions were even more effective. CONCLUSIONS: Based on our simulations, acute and chronic cases of HCV infection are remaining constant or slightly decreasing in the United States. Improving early screening and increasing access to treatment in adults may be an effective strategy for reducing the number of HCV infected children in the United States.

Evaluation of respondent-driven sampling in seven studies of people who use drugs from rural populations: findings from the Rural Opioid Initiative.

BACKGROUND: Accurate prevalence estimates of drug use and its harms are important to characterize burden and develop interventions to reduce negative health outcomes and disparities. Lack of a sampling frame for marginalized/stigmatized populations, including persons who use drugs (PWUD) in rural settings, makes this challenging. Respondent-driven sampling (RDS) is frequently used to recruit PWUD. However, the validity of RDS-generated population-level prevalence estimates relies on assumptions that should be evaluated. METHODS: RDS was used to recruit PWUD across seven Rural Opioid Initiative studies between 2018-2020. To evaluate RDS assumptions, we computed recruitment homophily and design effects, generated convergence and bottleneck plots, and tested for recruitment and degree differences. We compared sample proportions with three RDS-adjusted estimators (two variations of RDS-I and RDS-II) for five variables of interest (past 30-day use of heroin, fentanyl, and methamphetamine; past 6-month homelessness; and being positive for hepatitis C virus (HCV) antibody) using linear regression with robust confidence intervals. We compared regression estimates for the associations between HCV positive antibody status and (a) heroin use, (b) fentanyl use, and (c) age using RDS-1 and RDS-II probability weights and no weights using logistic and modified Poisson regression and random-effects meta-analyses. RESULTS: Among 2,842 PWUD, median age was 34 years and 43% were female. Most participants (54%) reported opioids as their drug of choice, however regional differences were present (e.g., methamphetamine range: 4-52%). Many recruitment chains were not long enough to achieve sample equilibrium. Recruitment homophily was present for some variables. Differences with respect to recruitment and degree varied across studies. Prevalence estimates varied only slightly with different RDS weighting approaches, most confidence intervals overlapped. Variations in measures of association varied little based on weighting approach. CONCLUSIONS: RDS was a useful recruitment tool for PWUD in rural settings. However, several violations of key RDS assumptions were observed which slightly impacts estimation of proportion although not associations.

The relationship between felt stigma and non-fatal overdose among rural people who use drugs.

BACKGROUND: Drug overdose deaths in the United States exceeded 100,000 in 2021 and 2022. Substance use stigma is a major barrier to treatment and harm reduction utilization and is a priority target in ending the overdose epidemic. However, little is known about the relationship between stigma and overdose, especially in rural areas. We aimed to characterize the association between felt stigma and non-fatal overdose in a multi-state sample of rural-dwelling people who use drugs. METHODS: Between January 2018 and March 2020, 2,608 people reporting past 30-day opioid use were recruited via modified chain-referral sampling in rural areas across 10 states. Participants completed a computer-assisted survey of substance use and substance-related attitudes, behaviors, and experiences. We used multivariable logistic regression with generalized estimating equations to test the association between felt stigma and recent non-fatal overdose. RESULTS: 6.6% of participants (n = 173) reported an overdose in the past 30 days. Recent non-fatal overdose was significantly associated with felt stigma after adjusting for demographic and substance use-related covariates (aOR: 1.47, 95% CI: 1.20-1.81). The association remained significant in sensitivity analyses on component fear of enacted stigma items (aOR: 1.48, 95% CI: 1.20-1.83) and an internalized stigma item (aOR: 1.51, 95% CI: 1.07-2.14). CONCLUSIONS: Felt stigma related to substance use is associated with higher risk of non-fatal overdose in rural-dwelling people who use drugs. Stigma reduction interventions and tailored services for those experiencing high stigma are underutilized approaches that may mitigate overdose risk.

Methods for Decreasing Preweaning Mortality in a Fragile Mouse Model of Hypomorphic Collagen VII Deficiency.

Preweaning mortality is a widespread problem in laboratory mouse breeding, particularly in the case of fragile mouse models. While numerous studies explore alternative care methods to increase the survivability of common mouse strains, there remains a paucity of research into the care of mice with fragile health conditions that result from induced or natural genetic mutations. In this study, standard husbandry practices were enhanced by the addition of a softened diet, a nutritionally fortified dietary supplement, soft bedding, gentle handling techniques, decreased handling, lengthened weaning age, and dam productivity tracking. This alternative care plan was shown to increase the survival of a fragile recessive dystrophic epidermolysis bullosa mouse model, and some aspects could be used in developing a care plan for other fragile mouse strains.

A qualitative study of clinicians' and individuals' with lower limb loss perspectives on the development of a novel online self-management program.

PURPOSE: To explore the rehabilitation preferences and experiences of clinicians and patients for education after lower limb loss to facilitate the development of an online self-management program. METHODS: A qualitative descriptive approach was used. Thirty-one clinicians (physiotherapists, occupational therapists, and prosthetists), and 26 patients with lower limb loss (transtibial and transfemoral amputation; mean age (SD) of 63.3 (9.1), years) were recruited. We used semi-structured focus groups and one-on-one interviews, and audio recorded the interviews. Data were analyzed using conventional content analysis. RESULTS: Three themes were identified: (1) Needing education in rehabilitation described the education in current practice as one-on-one discussion and booklets and highlighted the limitations of education such as its length, static nature, and inaccessible for patients living in remote areas. (2) Getting back to activities prior to amputation emphasized how goal setting and social support could assist patients and facilitate self-management. (3) Augmenting learning highlighted the need for an accessible complementary source for education and potential solutions to overcome the barriers of online delivery. CONCLUSIONS: Our findings underscore the importance of education in the rehabilitation of patients to help them get back to their activities. An online accessible tool may improve education by providing information and peer support.

Self-management education assists patients through knowledge and skills to adapt to an amputation.Education should be patient centred.An accessible user-friendly online tool which offers the information and peer support may augment and improve the delivery of self-management education.

What are relevant predictors of physical activity in older adults with lower limb loss (LLL)? Results of a retrospective analysis.

BACKGROUND: People with lower limb loss (LLL) have reduced physical activity (PA). There is evidence of physical and psychosocial predictors of PA in older adults with limb loss. However, these 2 areas (physical/psychosocial) have not been evaluated in the same analysis. OBJECTIVES: To describe and identify predictors of PA in individuals with LLL. STUDY DESIGN: Cross-sectional study. METHODS: Secondary analysis of data from a multisite Canadian randomized control trial involving community-dwelling prosthetic ambulators with unilateral transtibial or transfemoral amputation (N = 72). The dependent variable was the Physical Activity Scale for the Elderly. Potential predictors were four step square test, 2-minute walk test, Short Physical Performance Battery, Life Space Assessment, walking while talking test, and Activities-specific Balance Confidence scale. RESULTS: Seventy-two community-dwelling lower limb prosthesis users were enrolled. The sample included 62 male participants (86%), and 58 participants (81%) had transtibial amputation. The average age of participants was 65 (8.9) years, and for 49 participants (70%), the amputation was over 24 months ago. The total mean Standard Deviation (SD) Physical Activity Scale for the Elderly score was 153.2 (88.3), with scores of 148.1 (11.4) and 184.5 (24.7) for male and female participants, respectively. Regression analysis identified Life Space Assessment (ß = 1.15, p = 0.007) and Short Physical Performance Battery (ß = 3.51, p = 0.043) as statistically significant predictors accounting for 25% of the variance in PA. CONCLUSIONS: Community mobility and physical performance are the most meaningful predictors of PA. Future research should examine additional factors (e.g., environment, motivation). Understanding the predictors for PA after LLL would improve clinical practice as clinicians would have increased knowledge to modify and improve training.
