"Crafting a 'TransitionOmeter': A Proposed Framework for Developing and Honing Capabilities of Young People Transitioning to Adult Healthcare Services."

This paper focuses on an innovative approach to preparing children and young people, with Spina Bifida, to move from child-centered to adult-oriented healthcare systems. Reflecting on our role in delivering a national nurse led service, we set to identify and critique international transition tools in use for this population. Specifically, we aimed to identify the core capabilities and indicators of progression to successful transition, so that holistic interventions could be planned to match the needs of individuals and their carers. There were two phases to the study, initially focusing on a systematic literature review on transition tools and the specific items that these tools captured, including skills, abilities and behaviors. Phase two culminated in the articulation of a segmented and incremental "road map", aligned with facets deemed essential for a successful healthcare transition. The reporting of the literature review (phase one) followed the PRISMA guidelines and shaped the qualitative element of the study (phase two) through the use of semi-structured interviews and thematic analysis. The search strategy yielded 11 studies, which were then manually searched for other relevant literature, adding a further 14 articles. The review analyzed 7 specific tools for spina bifida and 8 generic tools, which were deemed appropriate for this group of patients. A comprehensive list of core capabilities was then articulated and framed to fit a progression timeline. Specific interventions were formulated to explore ways to co-produce resources that could enhance and support a planned transition to adult-focused services. Our proposed mapping of capabilities and progression could shape other transition programs, where nurses work collaboratively with young people, carers and other members of a team. More work is needed to further explore and embed the framework that, as we did, could be digitized and shared with all stakeholders involved in the transition process.

Identifying Adolescent Vaping With Screening to Brief Intervention and Brief Screener for Tobacco, Alcohol, and Drugs Screening Tools.

PURPOSE: This study aimed to determine whether the modified Screening to Brief Intervention (S2BI) and Brief Screener for Tobacco, Alcohol, and Drugs (BSTAD) that included e-cigarettes/vaping as examples could identify all nicotine and cannabis use or whether additional questions specifically about vaping are needed. METHODS: Between July 2020 and February 2022, adolescents recruited from primary care or an outpatient adolescent substance use disorder program were randomized to complete S2BI or BSTAD followed by specific questions about vaping. Screen questions were updated to include "vaping" in the parenthetical examples of nicotine and cannabis use. RESULTS: Data from 502 adolescent participants who completed both the S2BI or BSTAD and vaping questions were analyzed. The S2BI and BSTAD identified 92% (23/25) and 100% (16/16) of nicotine vaping and 100% (16/16) and 95.5% (21/22) of cannabis vaping, respectively. DISCUSSION: The S2BI and BSTAD tools accurately identify nicotine and cannabis use without specific questions about vaping.

Diagnostic performance of a rapid immunochromatographic test for the simultaneous detection of antibodies to Theileria equi and Babesia caballi in horses and donkeys.

BACKGROUND: Equine piroplasmosis is caused by two tick-borne protozoan parasites, Theileria equi and Babesia caballi,, which are clinically relevant in susceptible horses, donkeys, and mules. Moreover, equine piroplasmosis significantly constrains international trading and equestrian events. Rapidly diagnosing both parasites in carrier animals is essential for implementing effective control measures. Here, a rapid immunochromatographic test for the simultaneous detection of antibodies to T. equi and B. caballi was evaluated using samples from horses and donkeys collected in Greece, Israel, and Italy. The results were compared with an improved competitive enzyme-linked immunosorbent assay (cELISA) for detecting antibodies to both parasites using the same panel of samples. METHODS: Blood samples were collected from 255 horses and donkeys. The panel consisted of 129 horses sampled at four locations in northern Greece, 105 donkeys sampled at four locations in Sicily, and 21 horses sampled at two locations in Israel. The rapid test and the cELISA were performed according to the manufacturer's instructions, and the results were subjected to a statistical analysis to determine the sensitivity and specificity of both tests and their association. RESULTS: The immunochromatographic test provided a result within 15 min and can be performed in the field, detecting both pathogens simultaneously. The overall coincidence rate between the rapid test and the cELISA for detecting antibodies against T. equi was 93% and 92.9% for B. caballi. The rapid test's sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for T. equi were above 91.5%. Sixteen samples were positive for both parasites in the rapid test and eight in the cELISA. Either test had no significant association between T. equi and B. caballi detection. The detection rates of both parasites were significantly higher in Italy than in Greece or Israel and in donkeys than in horses. The agreement for T. equi between the results of both tests was high in Greece (93.8%) and Italy (95.2%) and moderate in Israel (76.2%). For B. caballi, the specificity and NPV of the rapid test were high (94.2% and 98.3%, respectively), although the sensitivity and PPV were moderate (69.2% and 39.1%, respectively) due to the small sample size. However, for B. caballi, the sensitivity was higher with the rapid test. CONCLUSIONS: The rapid test detected T. equi and B. caballi simultaneously in the field, potentially replacing laborious cELISA testing and is recommended for import/export purposes. The test can also be helpful for the differential diagnosis of clinical cases, since seropositivity may rule out equine piroplasmosis since it does not indicate current or active infection.

Engagement, initiation, and retention in medication treatment for opioid use disorder among young adults: A narrative review of challenges and opportunities.

INTRODUCTION: Opioid Use Disorder (OUD) is a catastrophic public health problem for young adults (YAs) and their families. While medication for OUD (MOUD) is safe, effective, and recognized as the standard of care, its' uptake and success have been limited in YAs compared to older adults. METHODS: This narrative review summarizes the existing literature and highlights select studies regarding barriers to YA MOUD, potential explanations for those barriers, and strategies to overcome them. RESULTS: Barriers are prominent along the entire cascade of care, including: treatment engagement and entry, MOUD initiation, and MOUD retention. Hypothesized explanations for barriers include: developmental vulnerability, inadequate treatment system capacity, stigma against MOUD, among others. Interventions to address barriers include: promotion of family involvement, increasing provider capacity, integration of MOUD into primary care, assertive outreach, and others. CONCLUSIONS: Integrating an adapted version of family coaching from the Community Reinforcement Approach and Family Training (CRAFT) and other models into YA MOUD treatment serves as an example of an emerging novel practice that holds promise for broadening the funnel of engagement in treatment and initiation of MOUD, and enhancing treatment outcomes. This and other developmentally-informed approaches should be evaluated as part of a high-priority clinical and research agenda for improving OUD treatment for YAs.

Persistence of Anti-Rabies Antibody Response in Horses Following Vaccination.

Rabies is a fatal zoonotic disease affecting all mammalian species. It is caused by the rabies virus and is prevalent worldwide. Horses are not commonly infected with rabies but their vaccination is recommended due to the potential zoonotic risk. This study aimed to evaluate the duration of immunity following rabies vaccination in horses. A total of 126 serum samples were collected from 93 horses, vaccinated 6 to 91 months before sampling. Rabies-virus-neutralizing antibody (RVNA) levels were evaluated using the Rabies Fluorescent Focus Inhibition Test (RFFIT). A protective RVNA titer of above 0.5 IU/mL was found in 112 (88.9%) of the samples and 84 (90.3%) of the horses. Antibody titers declined over time (rho = -0.271, p = 0.002); however, there was no significant difference in antibody titers or the prevalence of unprotected horses between the time intervals following vaccination. Purebred horses had lower antibody titers (p = 0.024). The response to booster vaccination was inspected in ten horses, and increased antibody titers were found in eight of them. The results of this study demonstrate the prolonged persistence of protective immunity in horses following rabies vaccination, in some cases, for up to eight years. Therefore, the current annual vaccination strategy should be re-evaluated. A rate of 9.7% of poor responders should be considered from an epidemiological perspective in order to minimize the risk of emergence of the disease.

Comparing the Performance of World Mental Health Composite International Diagnostic Interview Substance Abuse Module in Adolescents to Diagnoses Made by Pediatric Addiction Medicine Specialists.

OBJECTIVES: The World Mental Health Composite International Diagnostic Interview Substance Abuse Module (WMH-CIDI-SAM) is commonly used as a criterion standard measure for substance use disorder (SUD) diagnoses, although the accuracy of this tool when used with adolescents is unknown. The objective of this study was to evaluate the agreement between SUD diagnoses for adolescents made by WMH-CIDI-SAM and those made by specialists based on Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) ( DSM-5 ) SUD criteria during an SUD evaluation. METHODS: Adolescents aged 12 to 17 years presenting to an outpatient SUD program for youth were administered the WMH-CIDI-SAM by a trained research assistant, and results were compared with diagnoses made by experienced clinicians based on DSM-5 SUD criteria during an initial SUD evaluation. Chance-corrected concordance was estimated using the κ coefficient for the comparisons. RESULTS: The level of concordance between the WMH-CIDI-SAM interview and the clinician diagnosis based on DSM-5 SUD criteria were fair to moderate for alcohol use disorder and tobacco use disorder and poor for cannabis use disorder. Three of 11 WMH-CIDI-SAM item constructs showed poor concordance with clinician diagnosis. CONCLUSIONS: Interpreting the diagnostic criteria for SUDs, particularly cannabis use disorders, is nuanced, and the meaning of the criteria may be misunderstood by adolescents. Further evaluation of the performance of the WMH-CIDI-SAM diagnostic interview for identifying cannabis use disorders in adolescents is needed.

Parent Guidance on Alcohol Use for Youth With Chronic Medical Conditions.

PURPOSE: Youth with chronic medical conditions are vulnerable to unique alcohol-related health consequences, yet there are few prevention strategies targeting this group. Youth with chronic medical conditions parents' beliefs and provision of alcohol-related guidance have not yet been explored, which limits the development of effective family-based interventions. METHODS: We evaluated baseline surveys of youth with chronic medical conditions and their parents (n = 268 dyads) enrolled in a randomized controlled trial of a psychoeducational intervention to reduce alcohol use by youth with chronic medical conditions. Surveys evaluated youth alcohol use, parent beliefs about their child's alcohol use, and parental provision of alcohol guidance, including disease-related and disease-independent (ie, "drinking and driving") topics. Paired bivariate tests (χ 2 , Fisher exact) were used to measure associations between youth with chronic medical conditions alcohol use and parent alcohol-related beliefs and provision of alcohol-related guidance. RESULTS: In this study of 268 parent-youth dyads, many parents did not provide guidance on disease-specific topics, such as mixing alcohol with medications (47.8%) or risk of flares (37.6%). Furthermore, youth with chronic medical conditions whose parents had expectant beliefs about alcohol use (ie, alcohol use is "inevitable" or "OK with supervision") were more likely to report alcohol use (all P values <0.05). DISCUSSION: These findings suggest parent beliefs may influence youth with chronic medical conditions alcohol use. Proactive, disease-specific education from medical providers to parents of youth with chronic medical conditions may help to reduce adverse consequences of alcohol use in these vulnerable youth.

Substance Use and Educational Impacts in Youth With and Without Chronic Illness.

INTRODUCTION: Alcohol, cannabis, and nicotine are commonly used psychoactive substances that affect adolescent neurocognition. Little is known about the educational impacts of their use on measures of educational performance, participation and problems, especially among youth with a chronic illness who may use these substances to alleviate stress and symptoms. METHODS: Adolescents receiving general or subspecialty care were administered an electronic survey from 2016 to 2018. Data were analyzed in 2023. Using modified Poisson models, cross-sectional associations between past 12-month usage of alcohol, cannabis, and/or nicotine and educational impacts were estimated. RESULTS: Among 958 adolescents (mean age 16.0 years (SD 1.3), 564 (58.9%) female gender, 445 (46.5%) in subspecialty care), 294 (30.7%), 220 (23.0%), and 126 (13.2%) reported past 12-month use of alcohol, cannabis, and nicotine respectively, while 407 (42.5%) reported ≥1 educational impact, including recent lower grades 210 (21.9%), past 3-month truancy from school 164 (17.1%) or activities 170 (17.7%), and detention 82 (8.6%). Use of cannabis, but not other substances, was associated with negative educational impacts: lower grades (mostly C's/D's/F's), adjusted prevalence ratios [APR, (95% CI)] 1.54 (1.13-2.11); past 3-month truancy from school [2.16 (1.52-3.07)]; detention [2.29 (1.33-3.94)]. The association between cannabis use and any negative educational impact was stronger among adolescents with a chronic illness (p<0.001). CONCLUSIONS: Among adolescents, cannabis use was associated with a heightened risk of negative educational impacts, even after controlling for alcohol and nicotine use. Adolescents with chronic illness were especially likely to experience negative educational impacts. Findings underscore need for preventive interventions and messaging to reduce risks.

Returning Genetic Information About Risk for Alcohol Use Disorder to Adolescents: Findings of a Preliminary Qualitative Study of Precision Prevention.

Introduction: Alcohol use disorders are heritable, with genetic factors predicting approximately 50% of the risk. Returning information about genetic risk could promote avoidance of alcohol, reducing alcohol use disorder risk. This study explored attitudes toward a precision prevention model of alcohol use disorder targeting adolescents. Methods: This study conducted interviews with adolescents and adults to explore attitudes about precision prevention of alcohol use disorders. Interviews were recorded, transcribed, and thematically analyzed to identify perceptions about acceptability, salience, potential harms, and benefits. Results: Among N=13 participants (mean age 28.6 years, 7 female), 5 had undergone genetic testing, and 6 had a personal or family history of substance use disorder. Attitudes were favorable toward precision prevention of alcohol use disorders for adolescents. Perceived benefits included the potential to engage youth, motivate behavior change, protect family by sharing genetic information, and prompt insight into family problems. Perceived harms included the potential for anxiety, false sense of immunity from alcohol use disorders should genetic testing indicate no heightened risk, and experience of stigma from disclosure or breach of privacy. Conclusions: This qualitative study identified the potential harms and benefits of a precision prevention approach for addressing alcohol use disorder risk targeting adolescents, along with appreciation for the complexities of the model. Research is needed to elucidate operational, ethical, and communication strategies to advance the model.

An eHealth Prevention Program for Substance Use, Sexual Assault, and Sexual Risk Behaviors for Adolescents in Primary Care: Pilot Feasibility Randomized Controlled Trial of Teen Well Check.

BACKGROUND: Substance use, sexual assault, and sexual risk behaviors are common among adolescents and are interrelated. Nearly 1 in 5 adolescents use substances before sexual encounters, placing these young people at risk for both sexual assault and sexual risk behaviors. Primary care visits present a unique opportunity to address multiple health risk behaviors. OBJECTIVE: Teen Well Check is a web-based integrated prevention program for substance use, sexual assault, and sexual risk behaviors with demonstrated usability and acceptability among patients and providers. The aim of this study was to conduct a pilot randomized controlled trial to assess feasibility. METHODS: Adolescents (n=123) aged 14 to 18 years from diverse backgrounds were recruited from primarily Medicaid-serving pediatric primary care clinics. Participants completed a baseline survey; were randomized to receive Teen Well Check or an assessment-only control; and completed 1-, 3-, and 6-month follow-up surveys. Feasibility was assessed in terms of recruitment and retention rates. Preliminary changes from baseline to follow-up periods were examined separately in the Teen Well Check and control conditions. RESULTS: We recruited 123 participants (Teen Well Check: n=61, 49.6%; control: n=62, 50.4%). Of the 61 participants assigned to the Teen Well Check condition, 55 (90%) completed the full program and viewed all intervention content. Of the 123 participants, 105 (85.4%) were retained across at least 1 follow-up period, and there was no difference in follow-up rates between the conditions (χ21=0.6; P=.43). The completion of Teen Well Check took an average of 6.2 (SD 5.8) minutes. Preliminary analyses revealed that there were significant reductions in perceived peer norms (descriptive norms) for substance use before sex across follow-ups among participants in the Teen Well Check condition (P=.001 from baseline to 6 months), whereas there were significant increases among participants in the control condition (P=.003 from baseline to 6 months). In addition, there were nonsignificant reductions in substance misuse risk from baseline to the 6-month follow-up among participants in the Teen Well Check condition (P=.16). CONCLUSIONS: These findings support the feasibility of Teen Well Check delivery within pediatric primary care clinics. A randomized clinical trial is needed to assess efficacy.

Substance Use Screening, Brief Intervention, and Referral to Treatment in Pediatric Primary Care, School-Based Health Clinics, and Mental Health Clinics.

Adolescent cannabis use is a modifiable health behavior with potential adverse developmental, cognitive, psychological, and health effects. Over the last 2 decades, work to promote implementation of screening, brief intervention, and referral to treatment has improved screening, use of validated screening tools, and preventive messaging. Current intervention strategies for cannabis use are associated with modest, short-term effects, and referral to treatment is limited by availability of resources for adolescent substance use. This article provides an update on the evidence base for screening, brief intervention, referral to treatment, and the current state of implementation focused on management of cannabis use disorder.

Alcohol Use Patterns Among Underage Autistic and Non-Autistic Youth.

PURPOSE: We explored factors predicting repeated or hazardous alcohol use among autistic and non-autistic U.S. youth ages 16 to 20 years. METHODS: Autistic (n = 94) and non-autistic (n = 92) youth completed an online survey. By design, half of each group reported past-year alcohol use. We compared drinking patterns for autistic and non-autistic youth, and within each group between abstinent or infrequent drinkers (0-1 drinking episodes in past year) versus those who drank 2 + times in past year. RESULTS: Autistic (vs. non-autistic) youth who drank did so less frequently and consumed fewer drinks per occasion. However, 15% of autistic youth who drank in the past year reported heavy episodic drinking and 9.3% screened positive for AUDIT-C hazardous drinking. For autistic youth only, a diagnosis of depression, bullying or exclusion histories were positively associated with drinking 2 + times in the past year. Autistic youth who put more effort into masking autistic traits were less likely to report drinking 2 + times in the past year. As compared to non-autistic youth, autistic participants were less likely to drink for social reasons, to conform, or to enhance experiences, but drank to cope at similar rates. CONCLUSION: Repeated and hazardous underage alcohol occur among autistic youth. Targeted prevention programs designed to address the specific drinking profiles of autistic youth are needed.

The Impact of Cannabis Use on Adolescent Neurodevelopment and Clinical Outcomes Amidst Changing State Policies.

Cannabis is the most common illicit substance used by adolescents and the third most common psychoactive substance after alcohol and nicotine. Cannabis use during adolescence interrupts a critical period of brain development and leads to inappropriate activation of the reward pathway. Because the prefrontal cortex, which is responsible for impulse control and other executive functions, is not fully mature until the mid-twenties, the adolescent brain is especially vulnerable to damage from substance use. Although cannabis remains illegal at the federal level, recent changes in state policies have been associated with increased availability of a wide variety of cannabis products. As new products, formulations, and delivery devices that can deliver higher and faster peak doses of tetrahydrocannabinol enter the market, there is an even greater potential for cannabis to have negative clinical impacts on adolescent health. This article reviews the current literature on the impact of cannabis on adolescent health, including the neurobiology of the adolescent brain, potential clinical outcomes in adolescents who use cannabis, and the effects of changing state policies regarding cannabis on the increased availability of unregulated products.

The Association of Vaping With Social/Emotional Health and Attitudes Toward COVID-19 Mitigation Measures in Adolescent and Young Adult Cohorts During the COVID-19 Pandemic.

BACKGROUND: Vaping is a major health risk behavior which often occurs socially. Limited social activity during the COVID-19 pandemic contributed to worsening social and emotional health. We investigated associations among youth vaping, and reports of worsening mental health, loneliness, and relationships with friends and romantic partners (ie, social health), as well as perceived attitudes toward COVID-19 mitigation measures. METHODS: From October 2020 to May 2021, a clinical convenience sample of adolescents and young adults (AYA) reported on their past-year substance use, including vaping, their mental health, COVID-19 related exposures and impacts, and their attitudes toward non-pharmaceutical COVID-19 mitigation interventions, via a confidential electronic survey. Multivariate logistic regressions were used to estimate associations among vaping and social/emotional health. RESULTS: Of 474 AYA (mean age = 19.3 (SD = 1.6) years; 68.6% female), 36.9% reported vaping in the prior 12 months. AYA who self-reported vaping were more likely than non-vaping AYA to report worsening: anxiety/worry (81.1%; P = .036), mood (78.9%; P = .028), eating (64.6%; P = .015), sleep (54.3%; P = .019), family discord (56.6%; P = .034), and substance use (54.9%; P < .001). Participants who vaped also reported easy access to nicotine (63.4%; P < .001) and cannabis products (74.9%; P < .001). No difference in perceived change in social wellbeing was seen between the groups. In adjusted models, vaping was associated with symptoms of depression (AOR = 1.86; 95% CI = 1.06-3.29), less social distancing (AOR = 1.82; 95% CI = 1.11-2.98), lower perceived importance of proper mask wearing (AOR = 3.22; 95% CI = 1.50-6.93), and less regular use of masks (AOR = 2.98; 95% CI = 1.29-6.84). CONCLUSIONS: We found evidence that vaping was associated with symptoms of depression and lower compliance with non-pharmaceutical COVID-19 mitigation efforts among AYA during the COVID-19 pandemic.

Assessment of Screening Tools to Identify Substance Use Disorders Among Adolescents.

Importance: Efficient screening tools that effectively identify substance use disorders (SUDs) among youths are needed. Objective: To evaluate the psychometric properties of 3 brief substance use screening tools (Screening to Brief Intervention [S2BI]; Brief Screener for Tobacco, Alcohol, and Drugs [BSTAD]; and Tobacco, Alcohol, Prescription Medication, and Other Substances [TAPS]) with adolescents aged 12 to 17 years. Design, Setting, and Participants: This cross-sectional validation study was conducted from July 1, 2020, to February 28, 2022. Participants aged 12 to 17 years were recruited virtually and in person from 3 health care settings in Massachusetts: (1) an outpatient adolescent SUD treatment program at a pediatric hospital, (2) an adolescent medicine program at a community pediatric practice affiliated with an academic institution, and (3) 1 of 28 participating pediatric primary care practices. Participants were randomly assigned to complete 1 of the 3 electronic screening tools via self-administration, followed by a brief electronic assessment battery and a research assistant-administered diagnostic interview as the criterion standard measure for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) diagnoses of SUDs. Data were analyzed from May 31 to September 13, 2022. Main Outcomes and Measures: The main outcome was a DSM-5 diagnosis of tobacco/nicotine, alcohol, or cannabis use disorder as determined by the criterion standard World Mental Health Composite International Diagnostic Interview Substance Abuse Module. Classification accuracy of the 3 substance use screening tools was assessed by examining the agreement between the criterion, using sensitivity and specificity, based on cut points for each tool for use disorder, chosen a priori from previous studies. Results: This study included 798 adolescents, with a mean (SD) age of 14.6 (1.6) years. The majority of participants identified as female (415 [52.0%]) and were White (524 [65.7%]). High agreement between screening results and the criterion standard measure was observed, with area under the curve values ranging from 0.89 to 1 for nicotine, alcohol, and cannabis use disorders for each of the 3 screening tools. Conclusions and Relevance: These findings suggest that screening tools that use questions on past-year frequency of use are effective for identifying adolescents with SUDs. Future work could examine whether these tools have differing properties when used with different groups of adolescents in different settings.

A randomized controlled trial of varenicline and brief behavioral counseling delivered by lay counselors for adolescent vaping cessation: Study protocol.

Background: Approximately one-fifth of high-school seniors and college students currently vape nicotine. Adolescents express a desire to quit vaping, and case reports have shown promise for e-cigarette tapering with dual behavioral and pharmacologic therapies. However, there are no published clinical trials to date that test these intervention approaches for adolescent nicotine vaping cessation. In this three-arm randomized, placebo-controlled, parallel-group study, we aim to assess the efficacy of varenicline in combination with brief behavioral counseling and texting support on vaping cessation in adolescents dependent on vaped nicotine. Methods: The study will enroll 300 individuals between the ages of 16-25 with daily or near-daily nicotine vaping who reside in the Greater Boston area. Participants will be randomly assigned in a 1:1:1 ratio in blocks of six to one of the three arms: (1) a 12-week course of varenicline titrated to 1 mg bid, brief behavioral counseling delivered by a lay counselor, and an introduction to This is Quitting (TIQ) texting support created by the Truth Initiative; (2) a 12-week course of placebo, brief behavioral counseling, and TIQ; and (3) 12 weeks of enhanced usual care, consisting of advice to quit and an introduction to TIQ. The primary outcome will be biochemically verified continuous vaping abstinence at the end of the treatment (week 12). Secondary outcomes include continuous abstinence at follow-up (week 24), 7-day point prevalence abstinence at weeks 12 and 24, safety and tolerability of varenicline in an adolescent vaping population, as well as change in mood and nicotine withdrawal symptoms across the intervention period. Exploratory outcomes include change in comorbid substance use behaviors and nicotine dependence. Analysis will be intent-to-treat, with multiple imputation sensitivity analyses for participants with missing or incomplete outcome data. Discussion: This is the first study to evaluate varenicline in combination with a novel, brief, lay counselor delivered vaping cessation program for adolescents who vape nicotine. Results will inform clinicians on the effectiveness and acceptability of this promising, but not yet tested intervention.Clinical trial registration: ClinicalTrials.gov, identifier NCT05367492.

First Detection of Anti-Besnoitia spp. Antibodies in Equids in Israel and the Palestinian Authority.

Besnoitia is a tissue cyst forming coccidia, which affects multiple host species worldwide. Equine besnoitiosis is characterized mainly by generalized skin lesions and cysts in the scleral conjunctiva. Recent reports revealed exposure to Besnoitia in equines in Europe and the United States. However, the exposure to Besnoitia spp. in the Israeli equine population was never investigated. The aim of this study was to evaluate the seroprevalence and associated risk factors for besnoitiosis in equids in Israel. A cross-sectional serosurvey was performed using serum samples of apparently healthy horses (n = 347), donkeys (n = 98), and mules (n = 6), and exposure to Besnoitia spp. was determined by an immunofluorescent antibody test (IFAT). Anti-Besnoitia spp. antibodies were detected in 17.7% equids, 6.9% horses, 33.3% mules, and 55.1% donkeys. The seroprevalence in donkeys was significantly higher than in horses (p < 0.001). A significant association between the geographic location and seropositivity was found both in horses and donkeys, which was significantly higher (p = 0.004) in horses sampled in southern Israel, and donkeys sampled in Israel versus the Palestinian Authority (p < 0.001). This is the first serosurvey of Besnoitia infection in equines in Israel, and the results are consistent with reports from Europe. The clinical significance of equine besnoitiosis should be further investigated.

Teen Well Check: an e-health prevention program for substance use, sexual assault, and sexual risk behaviors for adolescents in primary care.

Objective: Adolescents are at risk for substance use, sexual assault, and sexual risk behaviours; however, to date no integrated prevention programmes address all three risk behaviours. The goal of this study was to evaluate the usability and acceptability of Teen Well Check, an e-health prevention programme targeting substance use, sexual assault, and sexual risk among adolescents in primary care settings.Methods: The current study included content analysis of interviews with adolescents in primary care (aged 14-18; n = 25) in the intervention development process, followed by usability and acceptability testing with qualitative interviews among adolescents in primary care (aged 14-18; n = 10) and pediatric primary care providers (n = 11) in the intervention refinement process. All data were collected in the Southeastern U.S.Results: Feedback on Teen Well Check addressed content, engagement and interaction, language and tone, aesthetics, logistics, inclusivity, parent/guardian-related topics, and the application of personal stories. Overall, providers reported they would be likely to use this intervention (5.1 out of 7.0) and recommend it to adolescents (5.4 out of 7.0).Conclusions: These findings suggest preliminary usability and acceptability of Teen Well Check. A randomized clinical trial is needed to assess efficacy.

Adolescents are at risk for substance use, sexual assault, and sexual risk behaviours.The goal of this study was to evaluate the usability and acceptability of Teen Well Check, an e-health prevention programme targeting substance use, sexual assault, and sexual risk among adolescents in primary care settings.Providers and adolescents rated Teen Well Check as usable and acceptable, and providers indicated that they would recommend it to their adolescent patients.

Substance Use Screening, Brief Intervention, and Referral to Treatment in Pediatric Primary Care, School-Based Health Clinics, and Mental Health Clinics.

High infection rates of Toxoplasma gondii in cattle, sheep and pigs from Israel.

Toxoplasma gondii is an obligate intracellular parasite belonging to the phylum Apicomplexa, which causes the zoonotic disease toxoplasmosis. T. gondii infects almost all warm blood animals. Generally, infected animals are asymptomatic and remain infected for life. Infection of humans occurs by consumption of infected undercooked meat or contaminated vegetables, fruit and water. The aim of this study was to evaluate the prevalence and seroprevalence of T. gondii in livestock in Israel. For the serological screening we investigated the presence of antibodies against T. gondii in sera using the indirect fluorescent antibody test (IFAT). Molecular screening was preformed using conventional PCR and nested PCR for the detection of T. gondii DNA in tissue samples. Serum samples of 249 cattle and 138 sheep were collected from farms. This serological survey showed high seroprevalence with seropositivity of 29 % in cattle and 33 % in sheep. In addition, 526 paired sera and tissue samples from cattle, sheep and pigs were obtained in slaughterhouses. The serological prevalence of T. gondii in healthy animals intended for human consumption was 29.4 % in cattle, 26.1 % in sheep and 8.1 % in pigs. The molecular detection of T. gondii in the tissue samples was 7.5 % in cattle, 7.3 % in sheep and 6.3 % in pigs. Considering the combined positive results from both serological and molecular assays, exposure to or infection with the parasite was present in 26.2 % of the samples (33.8 % in cattle, 30.3 % in sheep, 12.5 % in pigs). The prevalence of T. gondii in pigs was significantly lower compared to that of cattle and sheep (P < 0.001). All PCR positive samples from animals and 12 human positive samples were genotyped using a restriction fragment length polymorphism (PCR-RFLP) method. The results showed the existence of atypical genotypes in the majority of the samples and no correlation between animals and human samples could be determined from this study. Widespread exposure to T. gondii in Israel with the presence of parasite DNA in meat from cattle, sheep and pigs meant for human consumption was found.
