Social influence on drug use and sexual behaviors among rural LGBTQ+ individuals

ABSTRACT Background: Traveling to meet sexual partners and substance use are associated with increased risk of infectious disease. It is important to understand what factors may increase substances use or increased infection transmission risk (IITR) sexual behaviors among rural LGBTQ+ individuals. Objective: This study investigates substance use and sexual behaviors associated with increased infection transmission risk among rural LGBTQ+ individuals, and how these are associated with relationship type (friends or romantic partners) and travel distance. Methods: Participants (18 years+, identify as LGBTQ+, and provided a $25 gift card) were recruited from Illinois (25 counties), in 2021. Data included demographics, sexual and drug use behaviors, and assessed how these behaviors varied by relationship type and distance traveled (e.g. when meeting friends out-of-state). Results: The 398 participants were 79.1% White and 12.3% Black. By orientation, 29% heterosexual, 36% gay/lesbian, and 35% bisexual/other. By identity, 43% cisgender male, 51% cisgender female, and 6% genderqueer/other. Alcohol use while visiting out-of-state friends was more frequent among transgender (vs cisgender men; OR = 9.686, 95% confidence interval = 2.123-44.19), and individuals traveling > 1/month (all p < .050). Infection-related sexual behaviors while visiting out-of-state romantic partners was more frequent among prescription medication misuse (all p < .050) and traveling > 1/week (vs < 1/month; OR = 3.399, 95% CI = 1.037-11.144). Conclusion: This study of rural LGBTQ+ identified that alcohol use was associated with travel to visit out-of-state romantic partners, and prescription medication misuse increased infection-related sexual behavior during out-of-state travel. Health professionals can develop substance use and increased infection transmission risk sexual behavior interventions on gender minority groups in rural areas and target those who are traveling.

PREVALENCE OF SELF-MEDICATION PRACTICE AMONG THE PEOPLE IN NANGARHAR, AFGHANISTAN

Self-medication, the practice of using medication without medical supervision, is widespread in many low-income settings, including Afghanistan, where access to healthcare services can be limited. Despite its convenience, self-medication carries significant risks, such as drug resistance and adverse reactions, particularly with the misuse of antibiotics and other prescription medications. Objective: This study aimed to assess the prevalence and factors influencing self-medication practices among residents of Nangarhar, Afghanistan, focusing on common illnesses and types of medications used. Methods: A cross-sectional survey was conducted between January and June 2024 among 1,020 individuals, both male and female, aged 18 years and above, across Nangarhar. Participants were selected through random sampling. Data collection was performed using structured questionnaires, which gathered information on demographics, types of illnesses, medications used, and factors influencing self-medication practices. Descriptive and inferential statistical analyses were performed using SPSS software. Results: Of the total respondents, 62.6% reported self-medicating in the past six months. The most commonly reported ailments leading to self-medication were pain relief (45.2%), fever (39.8%), headache (38.7%), and gastrointestinal issues (27.5%). Antibiotics (46.1%) and analgesics (43.3%) were the most frequently used medications without prescriptions. Key reasons for self-medication included easy access to pharmacies (64.7%), high costs of healthcare (57.2%), and previous experiences with similar symptoms (49.8%). Lack of awareness about the dangers of self-medication and a perceived lack of severity of symptoms were also major contributing factors. Conclusion: Self-medication is a prevalent practice among residents of Nangarhar, Afghanistan, driven largely by ease of access to medications, economic barriers to healthcare, and low health literacy. Public health interventions, including educational campaigns and stricter regulations on over-the-counter medication sales, are urgently needed to mitigate the potential risks associated with this practice.

Generation Rx: evaluation of medication misuse prevention education for older adults.

Increased medication misuse over the last two decades has prompted extensive discussion about the lack of evidence-based and evidence-informed prevention education programs targeting the topic. As older adults are high utilizers of medications, this is an important population to reach with such educational programming. This study was designed to assess the change in knowledge and behavioral intentions of older adult participants after attending an educational session focused on safe medication use utilizing the Generation Rx Older Adult Toolkit (GROAT) resources. The Generation Rx team at The Ohio State University College of Pharmacy (OSU COP) partnered with The Ohio State University Extension offices (OSU Extension) across the state of Ohio to provide GROAT educational programming in their communities. OSU Extension Educators were trained via the standardized virtual training program, Generation Rx Ambassadors. Program participants were surveyed immediately before and after the educational events. Pre- and post-survey data was then analyzed to assess knowledge gain and behavioral intentions about safe medication practices, as well as program perception and program satisfaction. Programming occurred between May 2022 and September 2022. In total, OSU Extension Educators collectively engaged 843 individuals in a prevention education program utilizing the GROAT materials. After excluding participants under 50 years of age, there were 297 pre surveys and 245 post surveys included in the data analysis. Knowledge gains from pre- to post-survey showed a significant increase in correct responses in seven of the eight questions asked regarding safe medication practices. All five questions evaluating behavioral intentions demonstrated positive results after the programming (p < 0.001). Participants' perceptions and program satisfaction were also favorable. This study found through pre- and post-survey results that the Generation Rx Older Adult Toolkit programming delivered by Generation Rx trained OSU Extension Educators significantly increased older adult participants' knowledge and favorably impacted behavioral intentions around safe medication use practices.

Dosing and Misuse of Buprenorphine in the New Jersey Department of Corrections.

Opioid use disorder is common in incarcerated persons, and concern about the diversion of buprenorphine is a barrier to treatment. We conducted a retrospective chart review of incarcerated persons in the New Jersey Department of Corrections who received charges for misuse of medication, including buprenorphine, hypothesizing that the prescription of buprenorphine monoproduct, multiple tabs or films of buprenorphine, or higher doses of buprenorphine would be associated with more diversion incidents. Within the dosing range of 2 to 12 mg, there were more incidents of diversion of buprenorphine monoproduct (24.3%) compared with buprenorphine-naloxone (10.7%, p = .004). More incidents of diversion were seen when multiple films or tabs of buprenorphine product were prescribed (21.7%, comparison 12.7%, p = .01). This observation held when considering multiple buprenorphine-naloxone films, but not multiple buprenorphine tablets. No statistically significant association was found for institutional diversion charges related to higher doses of buprenorphine products. These results suggest that, within the dosing range of buprenorphine used in the New Jersey Department of Corrections, misuse charges were not associated with higher doses although were associated with prescribing buprenorphine monoproduct and multiple films of buprenorphine-naloxone.

The High Prevalence and Complexity of Over-the-Counter Medication Misuse in Older Adults.

Older adults (≥65 years) are the largest consumers of over-the-counter (OTC) medications and exceptionally vulnerable to the risks of these medications, including adverse drug events (ADEs). However, little is known about how older adults select and use OTCs. This is the first multisite study designed to prospectively quantify the type and intended use of OTCs selected by older adults in community pharmacies where products are purchased. Older adults (n = 144) were recruited from 10 community pharmacies from a Midwestern health system. Participants were given hypothetical symptoms and asked to select one or more OTCs for self-treatment. They were asked to report how they would use the products at symptom onset and when symptoms persisted or worsened. They also reported their current medication list and health conditions. Participants' OTC selections were evaluated for 4 types of misuse: drug-age, drug-drug, drug-disease, and drug-label. Of the 144 participants, 114 (79%) demonstrated at least one type of misuse when describing how they would use their OTC selections at symptom onset. Drug-drug and drug-label misuse had the highest prevalence. Overall, 26 (18%) and 28 (19%) participants showed only drug-drug or drug-label misuse, respectively. Notably, 55 (38%) of participants demonstrated misuse in 2 or more misuse categories. Misuse potential was exacerbated when participants described treating persistent or worsening symptoms. The results highlight the high prevalence and complexity of OTC misuse in older adults and the need for additional work to improve OTC safety.

Adolescents' Adverse Childhood Experiences, Poor Mental Health, and Substance Use During the COVID-19 Pandemic

PurposeAdverse childhood experiences (ACEs) increase the risk for poor mental health (MH) and substance use. We describe relationships between adolescents' ACEs, substance use, and poor MH occurring during the COVID-19 pandemic. MethodsWe conducted a secondary analysis of data among U.S. high school students aged <18 years, who participated in the nationally representative Adolescent Behaviors and Experiences Survey. Data were collected from January to June 2021. Bivariate and multivariable analyses assessed associations between individual ACEs (physical, emotional abuse by parent or caregiver, parent or caregiver job loss, food insecurity, sexual violence, physical dating violence, or cyber bullying) and cumulative ACEs (0, 1–2, 3, 4+) experienced during the pandemic and substance use; stratified analyses assessed effects of poor MH on associations between ACEs and substance use. ResultsUse of all substances was higher among adolescents with ACEs, particularly those who experienced both ACEs and poor MH during the COVID-19 pandemic. Prevalence of substance use was especially high among adolescents exposed to any sexual violence or physical dating violence. Compared to adolescents without ACEs, a higher percentage of adolescents with 4+ ACEs reported current use of alcohol (adjusted prevalence ratio [aPR], 5.32) or marijuana (aPR, 5.86), misuse of prescription pain medications (aPR, 8.82), binge drinking (aPR, 7.70), and increased alcohol (aPR, 6.54) or drug (aPR, 7.09) use during the pandemic. DiscussionThe individual and combined impact of ACEs and MH on adolescent substance use reinforce the need for trauma-informed care and primary prevention of ACEs to prevent and mitigate poor MH and substance use among adolescents.

Examining the Myth of Prescribed Stimulant Misuse among Individuals with Attention-Deficit/Hyperactivity Disorder: A Systematic Review.

The literature emphasizes the importance of addressing the misuse of ADHD medications as a potential significant healthcare issue within the general population. Nevertheless, there are no systematic reviews that specifically examine whether the misuse of psychostimulant medication among clinical populations diagnosed with ADHD who are undergoing prescribed stimulant therapy is a rational concern or a false myth. This systematic review was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 Statement. We searched PubMed databases for articles indexed up to 12th July 2023, without language restrictions. Our systematic search generated 996 unique articles. After a full-text revision, 13 studies met the eligibility criteria and were included in the systematic review. In the 50% of the study on the adult population, the reported prevalence of stimulant misuse was 0%. In other studies, the range of stimulant misuse rates varied from 2% to 29%, with no available data specifically focusing on the youth population. It has been noted that misuse of prescribed stimulant treatment is linked with particular subject characteristics, such as older age, prior or more frequent use of ADHD medication, use of short-acting medication, and a history of alcohol/substance misuse diagnosis. Despite certain limitations, our study highlights that while a significant proportion of individuals undergoing psychostimulant treatment for ADHD follow their prescribed medication regimens without resorting to misuse behaviors, there is variability in adherence, with occurrences of misuse behaviors. The misuse of prescribed ADHD treatment appears to be associated with distinct subject characteristics, underscoring the importance for tailored interventions addressing the specific requirements of these individuals to attain optimal treatment outcomes while mitigating misuse risks.

Retrospective Review of Congenital Anomaly Cases in Ruminants

This study was designed to provide data on the incidence rates of congenital anomalies and their distribution by organs and systems in calves, lambs and kids brought to Van Yuzuncu Yil University, Surgery Clinic between 2017-2023. The animal material of the study consisted of 1104 ruminants, including 886 calves, 183 lambs and 35 kids, aged 0-6 months. In addition to clinical examination, anomalies were diagnosed by using direct and indirect radiographic examinations when necessary. In some cases, a definitive diagnosis was made by performing experimental laparotomy based on clinical and radiological examinations. 341 out of 1104 ruminants, including 234 calves, 96 lambs and 11 kids, suffered from congenital anomalies. Of the ruminants with congenital anomalies, 208 (61.00%) were male, 132 (38.70%) female and 1 (0.30%) hermaphrodite. Abdominal wall anomalies were determined with the highest number of 112 (32.9%) cases. These were followed by musculoskeletal system anomalies in 83 (24.4%) cases and gastrointestinal system anomalies in 56 (16.5%) cases. Head region anomalies occurred in 41 cases (12.1%), urinary system anomalies in 23 cases (6.8%) and CNS anomalies in 9 cases (2.6%). Multiple anomalies were recorded in 16 (4.7%) cases. In conclusion, congenital anomalies are frequently seen as pathologies in ruminants in our country, especially in our region. Avoiding inbreeding, making artificial insemination widespread, improving the care and nutrition of the dam during pregnancy, correcting adverse environmental conditions and eliminating stress factors, avoiding over-the-counter medication misuse during pregnancy and most importantly informing field veterinarians and animal owners about the subject will contribute to the prevention of congenital malformations and losses in livestock.

Unsettling trend: The alarming rise of human abuse of veterinary drugs and its consequences.

Veterinary practitioners often prescribe many controlled drugs to animals that may include sedatives, tranquilizers, and painkillers. Unfortunately, many of these drugs are drugs that can be abused by humans, especially among the pet owners. Adequate measures are required to prevent or detect the misuse of veterinary drugs. In this article, the phenomenon of the rising misuse of veterinary medications by humans and their potential health hazards which can accompany the unsettling trends in society has been highlighted. This article aims to shed light on the extent of issues, exploring reasons behind human abuse and its consequences.

Self-prescription with psychotropic medications by healthcare professionals working at mental health institutions in Saudi Arabia.

Healthcare professionals who work in mental health institutions are more exposed to psychotropic medications than those in other healthcare institutions and are, therefore, more likely to self-prescribe. Self-prescription is a concerning phenomenon because of the potential for medication misuse, drug interaction, addiction, and other social, physical, and psychological consequences. This study investigated the prevalence of self-prescription of psychotropic medications and the most common self-prescribed psychotropic medications by healthcare professionals in mental health institutions in Saudi Arabia. It also aimed to determine the possible side effects and factors associated with self-prescription of psychotropic medications. This was a cross-sectional study using an electronic survey consisting of a researcher-designed checklist, targeting healthcare professionals in mental health institutions in Saudi Arabia. The independent variables were sex, nationality, occupation, place of residence, place of work, previous diagnosis of mental illness, marital, and living status. Data were analyzed, using SPSS, and frequency distribution and percentages were calculated. Chi-square test was employed to determine association between self-prescription and various independent variables. The final sample size was 588; 9.5% healthcare professionals working at mental health institutions in Saudi Arabia admitted to self-prescription with psychotropic medications. Almost half of those who admitted to self-prescription (48.2%) and about 1/4 (23.2%) self-prescribed selective serotonin reuptake inhibitors and benzodiazepines, respectively. The most commonly reported side effects of self-prescription were gastrointestinal symptoms and drowsiness. The study also suggested that males were significantly more prone to self-prescribing than females (P < 0.001). To our knowledge, this is the first study in Saudi Arabia to assess the self-prescription of psychotropic medications by healthcare professionals at mental health institutions. This study is important for decision-makers in their planning and updating of prescription policies. It is also equally important to spread awareness among healthcare professionals about the consequences of self-prescription.

Factors associated with the use of benzodiazepine and opioid prescription drug in the student population: a cross-sectional study

The misuse of benzodiazepines and opioid medications is frequent in students. To improve our understanding of this behavior, we aimed to identify factors associated with separate and concomitant use of these substances. Anonymous self-reported questionnaires were e-mailed to students enrolled at a French university between March and July 2021, covering: sociodemographic characteristics, academics, psychoactive substance use, ADHD symptomatology (adulthood and childhood), and psychiatric/psychological or addiction follow-up. Factors associated with the use of benzodiazepines and opioid medications included female sex (OR = 1.41 [1.08; 1.86]) and OR = 1.38 [1.06; 1.79], respectively), older age (OR = 1.65 [1.04; 2.6] and OR = 2.17 [1.4; 3.36], respectively), current psychiatric/psychological follow-up (OR = 6.53 [5.18; 8.24] and OR= 1.5 [1.12; 2.0], respectively), ADHD symptomatology (OR= 2.33 [1.71;3.16] and OR= 1.61 [1.15; 2.24], respectively), polyconsumption (tobacco use for benzodiazepine users, OR = 1.38 [1.04; 1.82]; alcohol use OR = 1.67 [1.17; 2.39] and tobacco use OR = 1.62 [1.23; 2.14] for opioid users). These factors were even more strongly associated with the concomitant use of benzodiazepines and opioid medications: older age (OR = 3.64 [2.22; 5.99]), female sex (OR = 1.54 [1.1; 2.14]), grade repetition (OR = 1.7 [1.14; 2.54]), psychiatric/psychological follow-up (OR = 4.51 [3.35;6.06]), ADHD symptomatology (OR = 5.3 [3.69; 7.63]), polyconsumption (tobacco use OR = 2.05 [1.39; 3] and cannabis use, OR = 2.07 [1.97; 4.16]. The factors associated with the use of benzodiazepines and prescription opioids identified in this study could lead to the development of targeted prevention methods.

The Ethical Stewardship of Artificial Intelligence in Chronic Pain and Headache: A Narrative Review.

As artificial intelligence (AI) and machine learning (ML) are becoming more pervasive in medicine, understanding their ethical considerations for chronic pain and headache management is crucial for optimizing their safety. We reviewed thirty-eight editorial and original research articles published between 2018 and 2023, focusing on the application of AI and ML to chronic pain or headache. The core medical principles of beneficence, non-maleficence, autonomy, and justice constituted the evaluation framework. The AI applications addressed topics such as pain intensity prediction, diagnostic aides, risk assessment for medication misuse, empowering patients to self-manage their conditions, and optimizing access to care. Virtually all AI applications aligned both positively and negatively with specific medical ethics principles. This review highlights the potential of AI to enhance patient outcomes and physicians' experiences in managing chronic pain and headache. We emphasize the importance of carefully considering the advantages, disadvantages, and unintended consequences of utilizing AI tools in chronic pain and headache, and propose the four core principles of medical ethics as an evaluation framework.

Trends in the nonmedical misuse of benzodiazepines and Z-hypnotics among school-aged adolescents (2016-2021): gender differences and related factors.

The misuse of psychotropic medication has increased during the past decade, especially among adolescents. The aim of our study was to describe the prevalence and patterns of the nonmedical use of benzodiazepines (BDZ) and Z-hypnotics among school-aged adolescents through the lens of sex. In addition, we sought to analyze the temporal evolution of the nonmedical use of these drugs during the period 2016-2021. The temporal evolution of the nonmedical use of these drugs was analyzed based on survey data collected in 2016, 2018 and 2021, which includes the first years of the COVID-19 pandemic. To assess the possible effect of the COVID-19 pandemic, the year at survey was conducted was introduced as a categorical variable. We used data from the Spanish State Survey on Drug Use in Secondary Education, which covers drug use among students aged 14-18 years. Using multivariate logistic regression models, we estimated the independent effect of different variables (sociodemographic data, use of other psychoactive substances, risk perception and availability) on the nonmedical use of BDZ and Z-hypnotics. In total, survey data from 95,700 adolescents were included in our analysis. The nonmedical use of BDZ and Z-hypnotics increased among adolescents during the study period. The adjusted odds ratio (AOR) from 2016 to 2018 was 1.11 (95% CI 0.94-1.31) and from 2018 to 2021 the AOR was 1.26 (95% CI 1.08-1.46), using 2016 and 2018, respectively, as reference years. The nonmedical use of BDZ and Z-hypnotics was more likely in adolescent girls than boys (AOR = 2.11). The nonmedical use of prescription opioids (AOR = 3.44), novel psychoactive substances and other illicit psychoactive drugs (AOR = 4.10) were risk factors for the nonmedical use of BDZ and Z-hypnotics in both sexes. Use of cannabis (AOR = 1.38) was a predictor of nonmedical use in female adolescents only. This study shows that the trend of the nonmedical use of BDZ and Z-hypnotics among school-aged adolescents in Spain increased between 2016 and 2021. Among adolescents aged 14 to 18, the probability of nonmedical use of these psychoactive substances was twice as high for female adolescents as for male adolescents.

Prescription drug monitoring programs and prescription pain medication misuse among U.S. high school students—2019

BackgroundPrescription drug monitoring programs (PDMPs) are state-level databases that track and inform prescribing practices to reduce prescription drug diversion and misuse. To our knowledge, only three studies have examined the impact of PDMPs on opioid-related outcomes among adolescents, and none have focused on prescription pain medication misuse among adolescents.MethodsThis study leveraged data from the 2019 National Youth Risk Behavior Survey (YRBS) to explore the associations between five categories of PDMP dimensions and the prevalence of self-reported prescription pain medication misuse. Demographic factors’ associations with self-reported prescription pain medication misuse were also examined.ResultsIn 2019, none of the PDMP dimensions were associated with self-reported prescription pain medication misuse among U.S. high school students, adjusting for gender, grade, race/ethnicity, and sexual orientation.ConclusionsNone of the five PDMP dimensions were associated with lower prescription pain medication misuse, however further research is needed, especially as new YRBS data become available.

Milligram scale enantioresolution of promethazine and its main metabolites, determination of their absolute configuration and assessment of enantioselective effects on human SY-SY5Y cells

The misuse of pharmaceuticals has significantly increased in recent decades, becoming a major public health concern. The risks associated with medication misuse are particularly high in cases of overdose, especially when the active substances are chiral, as enantioselectivity plays an important role in toxicity. Promethazine (PMZ) is a chiral antihistamine marketed as a racemate and it is misused in "Purple Drank", a recreational drug beverage, that combines codeine and/or PMZ, with soda or alcohol leading to serious health consequences and fatalities in consumers around the world, particularly among teenagers. Information regarding the enantioselectivity in the toxicity of (R,S)-PMZ and its main metabolites, namely promethazine sulfoxide (PMZSO) and desmonomethyl promethazine (DMPMZ), is unknown. This work reported, for the first time, the enantioseparation, in milligram scale, of (R,S)-PMZ, (R,S)-DMPMZ, (R,S)- PMZSO and the determination of their absolute configurations by electronic circular dichroism (ECD). The enantioseparation of all the six enantiomers was accomplished in a homemade semi-preparative column with amylose tris-3,5-dimethylphenylcarbamate (AD) coated with aminopropyl Nucleosil silica. The enantiomeric purity was evaluated using the analytical Lux® 3 µm i-Amylose-3 column, yielding enantiomeric purity values ranging between 94.4% and 99.7%. The elution order of all the enantiomers was accomplished combining the ECD results with an optical rotation detector. The elution order of the enantiomers was influenced only by the chiral selector, rather than the mobile phase.The cytotoxicity of the racemates and the isolated enantiomers towards differentiated SH-SY5Y cells was evaluated. (R,S)-DMPMZ exhibited a significantly higher cytotoxicity than (R,S)-PMZ, suggesting the metabolic bioactivation of (R,S)-PMZ. Conversely, no significant cytotoxicity was found for (R,S)-PMZSO, underscoring a metabolic detoxification pathway. Remarkably, enantioselectivity was observed for the cytotoxicity of PMZ; (R)-PMZ was significantly more cytotoxic than (S)-PMZ.The results underscore the importance to isolate the enantiomers in their enantiomerically form and their correct identification for toxicity enantioselectivity studies, which are vital to understand the drug's behaviour and safety, especially in case of overdoses.

Public Health Outreach in Impoverished Areas of Cambodia: Addressing the Issues Related to Prescription Practices

During a two-week public health internship organized by Projects Abroad in impoverished areas in Cambodia, the authors participated in health check-ups and outreach activities. We identified issues such as polypharmacy and medication misuse. These problems stem from symptom-based prescriptions without considering individual patient conditions due to limited diagnostic equipments and medications. Our solution involved suggesting a documentation akin to Japan's prescription record books, and Drug Information Leaflets (DILs). Prescription record books would enable patients to record the medications they purchased at the pharmacy, so that physicians would know what medications patients are taking during their health checkups, and thus prevent polypharmacy. In addition, the DILs included medication details and illustrations, considering the low literacy rates in the areas. We emphasized the need for sustained non-communicable diseases (NCDs) treatment and the potential of external perspectives to introduce innovative healthcare approaches and improvements within local communities.

Nasal Disorders.

Nasal obstruction, rhinorrhea, and epistaxis are common presenting concerns in primary care clinics. Nasal disorders affect the quality of life for many children and families. Rarely, these complaints may represent a life-threatening condition among infant obligate nasal breathers or cases of unusual pathology. The most common causes of rhinorrhea and nasal obstruction vary by age and include physiologic, infectious, allergic, foreign body, irritant, and traumatic causes. Less commonly, children may have congenital malformations, sinonasal masses, or autoimmune disease. The most common causes of epistaxis are inflammatory, environmental, and traumatic causes and medication misuse, but rarely, children may have predisposing anatomic, hematologic, or vascular abnormalities or even sinonasal tumors. In this article, we provide a thorough review of the common nasal disorders treated every day in primary care clinics and mention briefly some of the rare but serious cases that may be overlooked without considering a full differential diagnosis.

An Exploratory Study of Prescription Pain Medication Misuse with and without Heroin Use Among Adolescents

Abstract: Aims: Opioid misuse is an epidemic in the United States and globally, with adolescents affected by negative consequences including overdoses and deaths. Understanding how mental health and substance use relate to specific types of opioid use is thus important. Methods: Data from the 2019 Connecticut Youth Risk Behavior Survey were analyzed. Chi squares and adjusted odds ratios were computed to relate demographic variables, mental health, and substance use measures to misuse of prescription pain medications with and without heroin use, as compared to neither . Results: Among 1,931 high-school respondents, 8.8 % (n=180) reported prescription pain medication misuse (PPMM+), and 1.4 % (n=28) also reported using heroin (PPMM/HU+). PPMM+ was associated with being female while PPMM/HU+ was associated with being non-White and male. Poorer mental health was associated with PPMM+, and suicidality measures were strongly related to PPMM/HU+. Use of other substances was reported with PPMM+ and PPMM/HU+, with use of vapor products, including on school grounds, particularly linked to the latter. Conclusions: PPMM+ and PPMM/HU+ are associated with suicidality and substance use among adolescents, with suicidality particularly related to PPMM/HU+. Having access to and using substances on school property suggests the need for school-based and other interventions.

Tumour organoids and assembloids: Patient-derived cancer avatars for immunotherapy.

Organoid technology is an emerging and rapidly growing field that shows promise in studying organ development and screening therapeutic regimens. Although organoids have been proposed for a decade, concerns exist, including batch-to-batch variations, lack of the native microenvironment and clinical applicability. The concept of organoids has derived patient-derived tumour organoids (PDTOs) for personalized drug screening and new drug discovery, mitigating the risks of medication misuse. The greater the similarity between the PDTOs and the primary tumours, the more influential the model will be. Recently, 'tumour assembloids' inspired by cell-coculture technology have attracted attention to complement the current PDTO technology. High-quality PDTOs must reassemble critical components, including multiple cell types, tumour matrix, paracrine factors, angiogenesis and microorganisms. This review begins with a brief overview of the history of organoids and PDTOs, followed by the current approaches for generating PDTOs and tumour assembloids. Personalized drug screening has been practised; however, it remains unclear whether PDTOs can predict immunotherapies, including immune drugs (e.g. immune checkpoint inhibitors) and immune cells (e.g. tumour-infiltrating lymphocyte, T cell receptor-engineered T cell and chimeric antigen receptor-T cell). PDTOs, as cancer avatars of the patients, can be expanded and stored to form a biobank. Fundamental research and clinical trials are ongoing, and the intention is to use these models to replace animals. Pre-clinical immunotherapy screening using PDTOs will be beneficial to cancer patients. The current PDTO models have not yet constructed key cellular and non-cellular components. PDTOs should be expandable and editable. PDTOs are promising preclinical models for immunotherapy unless mature PDTOs can be established. PDTO biobanks with consensual standards are urgently needed.

Adverse Childhood Experiences and Prescription Stimulant Use in Adults: A Systematic Review.

Nonmedical prescription stimulant use (NPSU) is an ongoing public health crisis in the United States. There exists, however, a dearth of research investigating specific childhood risk factors that may contribute to this illicit use. Adverse childhood experiences (ACEs) may be a significant risk factor to address in the prevention and treatment of NPSU, as research has provided evidence for increased substance use, potentially including prescription stimulant misuse, among individuals who have experienced trauma. A systematic review of the literature was conducted to gather and synthesize research articles specifically examining the relationship between nonmedical prescription stimulant use in adults and the experience of adverse childhood experiences (ACEs). Four studies met all inclusion criteria and were included in the review. The results demonstrated that the nonmedical use of prescription stimulants in adults is significantly associated with ACEs, with a higher numerical count of ACEs associated with a greater likelihood of nonmedical prescription stimulant use. Gaps in the literature were identified, specifically noting a lack of information available regarding the relationship between ACEs and NPSU within gender- and racially diverse populations. The findings have implications for informing interventions related to ACEs and the misuse of prescription stimulant medication in adults.
