Leftover of Amoxicillin Suspension After Use by Children in the Netherlands.

PURPOSE: In clinical practice, a discrepancy may exist between the prescribed amount of a drug and the commercially available pack sizes in the pharmacy, potentially contributing to drug waste. This study aimed-as an example of this phenomena-to quantify leftover of amoxicillin suspension prescribed to children, due to discrepancies between physician-prescribed and pharmacy-dispensed amounts. METHODS: We performed a retrospective cohort study including amoxicillin suspension dispensations for patients aged 0-12 years between 2017 and 2019 utilizing the Dutch PHARMO database. Leftover amount of amoxicillin was estimated by assessing the discrepancy between the prescribed and dispensed amounts. Extrapolated amoxicillin weight and economic spillage estimates for the Netherlands were determined. The impact of two theoretical interventions on leftover amount was assessed: (1) introducing vials with half the volume of the current 100 and 30 mL vials and (2) a combination of the first intervention with a maximum of 10% round-down by the dispensing pharmacy of the prescribed dose. RESULTS: We included 79 512 amoxicillin suspension dispensations for 62 252 patients. The mean leftover amount of amoxicillin suspension per dispensing was 27%. The yearly amount of amoxicillin leftover was 49.8 kg in the study cohort, equivalent to yearly 633 kg and €621 000 when extrapolated to the Netherlands. Employing the first theoretical intervention reduced the mean leftover per dispensing to 20%, reducing the yearly leftover to 31.6 kg amoxicillin in the study cohort, and to 400 kg and €400 000 extrapolated. The second theoretical intervention further reduced leftover to 17%, reducing the yearly leftover to 24.3 kg amoxicillin in the study cohort, and to 300 kg and €300 000 extrapolated. CONCLUSION: Approximately a quarter of amoxicillin suspension remains as leftover per dispensing. Applying different theoretical intervention shows the potential for a significant reduction of amoxicillin leftover.

Sexually Transmitted Infection (STI) Incidence, STI Screening, and Human Immunodeficiency Virus Preexposure Prophylaxis Uptake in United States Veterans With Opioid Use Disorder in Long Island, New York.

Background: Opioid use disorder (OUD) confers increased risk of contracting bloodborne and sexually transmitted infections (STIs). Limited data exist on infectious disease screening and preexposure prophylaxis (PrEP) usage among United States Veterans (USVs) with OUD, including persons who inject drugs (PWID). This study aimed to evaluate the epidemiology of human immunodeficiency virus (HIV), hepatitis C virus (HCV), bacterial STIs, and PrEP uptake in USVs with OUD, including PWID. Methods: A retrospective chart review of USVs with OUD seeking care at Northport Veterans Affairs Medical Center between 2012 and 2022 was completed. Sociodemographics, HIV, HCV, STI testing rates and diagnosis, and PrEP uptake were compared between USVs, stratified by injection drug use history. Results: We identified 502 USVs with OUD; 43% had a history of injection drug use. Overall, 2.2% of USVs had HIV and 28.7% had HCV. An STI was diagnosed in 10% of USVs, most frequently syphilis (1.8%). PWID were more likely to be tested for HIV (93.5% PWID vs. 73.1% non-PWID; P < .001), HCV (95.8% PWID vs. 80.8% non-PWID; P < .001), and syphilis (80% PWID vs. 69.2% non-PWID; P = .006). Total gonorrhea and chlamydia testing rates were 31.9% and 33.7%, respectively, without difference between the groups. PrEP was prescribed in 1.2% of USVs. Conclusions: In USVs with OUD, gonorrhea and chlamydia screening occurred less frequently than syphilis, HCV, and HIV. PWID were more likely to be screened for HIV, HCV, and syphilis. PrEP uptake was low. Both PWID and non-PWID may benefit from increased STI screening and linkage to PrEP.

Development of Palpable Purpura in a Patient With Infective Endocarditis: A Case Report.

Infective endocarditis (IE) can present with a variety of signs and symptoms, including skin lesions. The few papers describing a relationship between IE and vasculitis are split between IE being able to mimic vasculitis and between IE indeed being associated with a vasculitis involving the skin, kidney, gastrointestinal tract, or peripheral nerves. It is important for clinicians to distinguish between an isolated vasculitis, infective endocarditis, and IE-associated vasculitis because the treatments and outcomes are different. We report a case of a patient with a history of intravenous (IV) drug use who initially presented with chest pain, was started on vancomycin following diagnosis of methicillin-resistant Staphylococcus aureus (MRSA) IE, left against medical advice (AMA), and then returned to the hospital due to development of a purpuric rash. We contend that while he did not have a skin biopsy due to time delay, his symmetrically distributed purpura was consistent with cutaneous vasculitis. His symptoms, including his rash and an acute kidney injury (AKI), improved with antibiotics to treat the endocarditis.

Ecstasy-Induced Rhabdomyolysis Leading to Severe Acute Kidney Injury Requiring Temporary Hemodialysis: A High Risk for Recurrence With Repeated Exposure.

Ecstasy (3,4-methylenedioxymethyl-amphetamine, MDMA) is an illicit drug that has found widespread use. It is mostly used by adolescents and young adults, particularly during intense and prolonged dance parties for its mood-enhancing properties. Despite these pleasurable effects, users may have potentially serious side effects including death. One of the serious side effects is rhabdomyolysis, which can proceed to severe acute kidney failure. Due to different personal characteristics, some individuals taking the same dose of MDMA may experience more adverse effects than others. Individuals who experience adverse effects are more likely to experience them with each use. Our patient used MDMA two times in his life, and on each occasion, he had severe rhabdomyolysis with severe acute kidney injury (AKI) requiring temporary hemodialysis. Health professionals should screen all adolescents and young adults for illicit drug use during each encounter and counsel them against it.

Exploration and Practice of Introducing the Pharmaceutical Care Network Europe Classification System to Psychiatric Drugs.

This research aims to summarize and discuss issues related to psychiatric drugs by using the classification system of the Pharmaceutical Care Network Europe (PCNE) and to provide a reference for the development and direction of clinical pharmacists' work in the future. Psychiatric patients who were hospitalized in our hospital from Janurary 2023 to December 2023 were enrolled. Drug-related problems (DRPs) were evaluated using the PCNE classification system (version 9.0). The types, causes, intervention plans, acceptance of intervention plans, and statuses of DRPs were analyzed. A total of 362 patients were included, covering 405 DRP cases, with an average DRP of 1.12 for each patient. All 405 DRP cases underwent interventions, with a success rate of 83.46%. The main categories of related drugs were psychotropic drugs (70.37%), anti-infective drugs (8.89%), and cardiovascular system drugs (5.19%). The main DRPs were possible adverse drug events (21.24%), poor treatment effects (69.14%), and unnecessary medication treatment (9.63%). The main causes of DRPs were inappropriate drug selection (18.52%), inappropriate combinations of drugs (16.05%), and excessive drug dosage (13.58%). The PCNE classification system helps clinical pharmacists improve their ability to identify and solve DRPs faced by psychiatric departments, improve pharmaceutical care efficiency, and ensure rational drug use.

Effects of natural environments on drug contents in nails: comparison of drug residual rates between nails and hair to determine the drug-use history of corpses in unnatural death cases using micro-segmental analysis.

PURPOSE: We previously developed evaluation methods using micro-segmental analysis (MSA) to examine the effects of external environments on drug content in hair and nails. In this study, the effects of the natural environmental factors (water, temperature, humidity, light, and soil) on drug contents in nails were examined and compared with our previous experimental data on hair. METHODS: Four hay-fever medicines were used as model drugs (fexofenadine, epinastine, cetirizine, and desloratadine) to evaluate drug stability in the nails. Reference nails containing the four medicines were collected from patients with hay fever who ingested the medicines daily for four months. The nails were exposed to various natural environments for up to four months. RESULTS: The effects of temperature, humidity, and light on drug contents in the nails were comparatively small. Soil significantly decomposed the nail surfaces and decreased the drug content of the nails (up to 17 %). Water also decreased the drug content (up to 12 %), although no apparent changes in nail surfaces were observed. CONCLUSIONS: In comparison with hair data obtained under the same environmental conditions, light affected drugs in the hair rather than in nails, whereas water and soil greatly affected drugs in the nails rather than in hair. Although the disposition of drugs incorporated in the tissues differed between nails and hair, the analytes were detected in nails and hair strands left in severe natural environments. MSA could be useful for estimating drug-use histories and personal profiles using the nails and hair of a corpse.

Outcomes of ST-Elevation Myocardial Infarction in Patients With Opioid Dependence: A National Inpatient Sample Study.

BACKGROUND: ST-segment elevation myocardial infarction (STEMI) is a critical condition characterized by the sudden obstruction of one or more coronary arteries, resulting in diminished blood flow to the heart muscle. This acute ischemic event demands swift and precise intervention to minimize myocardial damage and preserve cardiac function. Opioids, a class of potent analgesic medications, are frequently utilized in the management of STEMI-related chest pain. Despite their efficacy in alleviating discomfort, their use in this context warrants careful consideration due to potential adverse effects and interactions.  Methods: In this large nationwide retrospective observational study, we evaluated the effect of opioid dependence on inpatient mortality, length of hospitalization, and cost of hospitalization of patients with STEMI. Data was collected for 2019 from various hospitals across the United States using the National Inpatient Sample (NIS) through the Healthcare Cost and Utilization Project (HCUP). Using the International Classification of Diseases-10 codes (ICD-10), we identified a primary diagnosis of STEMI in patients over the age of 18, as well as a secondary diagnosis of opioid dependence.  Complex samples and multivariable logistic and linear regression models were used to determine the association of opioid dependence on inpatient mortality, length of hospitalization, and cost of hospitalization of patients with STEMI. Of the patients who fit our criteria, we identified other comorbidities and diagnoses associated with them as potential confounders including drug abuse, hypertension, diabetes, alcohol use, obesity, peripheral vascular disease, and chronic lung disease. Other confounders that were adjusted for include race, Charlson Comorbidity index, median household income, insurance, hospital region in the US, hospital bed size, and teaching status of the hospital.  Results: A total of 661,990 patients presented to a hospital with a primary diagnosis of STEMI in 2019. The majority of the patients were male with a mean age of 62.5+/-3.4 and were Caucasian American. Patients who were opioid dependent were found to be on average younger, earned less than the 25th percentile household income, had a higher history of illicit drug and alcohol use, and had Medicaid. They were also found to have higher rates of chronic lung disease at 39.2%, compared to 21.4.% in patients who were not opioid-dependent. Patients who were not opioid dependent were found to have higher rates of hypertension and type 2 diabetes mellitus. Inpatient mortality and cost of hospitalization in STEMI patients with opioid dependence were not statistically different compared to those who were not opioid dependent. However, STEMI patients who were opioid dependent did have an associated longer length of hospitalization.  Conclusion: Opioid use for pain relief in acute coronary syndrome, particularly STEMI, is a mainstay of treatment. Our retrospective cohort dived into assessing the relationship between opioid dependence on its effect on inpatient mortality, length of stay, and cost of hospitalization in STEMI patients. Our study showed that opioid dependence has no significant impact on inpatient mortality. However, it was associated with a longer length of hospital stay in STEMI patients. Further studies may be warranted into the effects of opioid dependence on the length of hospitalization in STEMI patients. .

Percutaneous Mechanical Aspiration in Infective Endocarditis: Applications, Technical Considerations, and Future Directions.

In recent years, there has been a shift in the epidemiology of patients with infective endocarditis (IE). This has been characterized by an alarming increase in IE in patients who inject drugs, cardiac implantable electronic device-related IE, and those with comorbid conditions and high surgical risk. This unmet need has mandated a reevaluation of complex management strategies in these patients and introduction of unconventional approaches in treatment. Percutaneous mechanical aspiration has emerged as both a diagnostic and therapeutic option in selected patients with IE. In this review, the authors discuss the gaps in care of IE, rationale, device armamentarium, procedural, and technical considerations and applications of percutaneous mechanical aspiration in IE.

Vision Loss and Substance Misuse: A Systematic Review.

Background: The number of people in the U.S. affected by sensory disabilities and/or substance use has continued to increase, but the relationship between them has yet to be fully understood. The purpose of this review is to assess the relationship between substance use and vision loss in the U.S. as described by current literature. Methods: A search of published literature was conducted across MEDLINE, APA PsycINFO, Web of Science, and EBSCO: Psychology and Behavioral Sciences Collection, and CINAHL following the Preferred Reporting Items for Systematic Reviews and Meta Analysis (PRISMA) protocol. Risk of bias was assessed by the authors based on study design. U.S. based studies written in English between 2010 and 2022 that reported on vision loss and substance use were included. Results: In all, 21 articles were included (case reports 11, case series 1, cross-sectional 4, retrospective cohort 3, review 2) representing 89,132 patients. Nineteen studies found a positive association between vision loss and substance use, with 15 studies suggesting substance use was a risk factor for vision loss. One study reported on vision loss preceding substance use but was inconclusive. Conclusions: Our findings suggest that substance use may be a risk factor for vision loss, and we recommend that providers screen for vision loss in at risk patients to mitigate further disability. Further research is needed to assess the impact visual disabilities may have on substance use, and stronger evidence is needed to verify if substance use is truly a risk factor for vision loss.

Increases in housing rules and surveillance during COVID-19: impacts on overdose and overdose response in a community-based cohort of sex workers who use drugs in Vancouver, BC.

INTRODUCTION: Since the beginning of the COVID-19 pandemic, COVID-19 risk mitigation measures have expanded to include increased rules and surveillance in supportive housing. Yet, in the context of the dual public health emergencies of COVID-19 and the unregulated drug toxicity crisis, we have not evaluated the unintended health and social consequences of such measures, especially on criminalized women. In order to address this dearth of evidence, our aim was to assess the association between increased housing rules and surveillance during COVID-19 and (a) nonfatal overdose, and (b) administration of naloxone for overdose reversal among women sex workers who use drugs in Vancouver, BC. METHODS: This study is nested within An Evaluation of Sex Workers Health Access (AESHA), a community-based prospective cohort of women sex workers in Metro Vancouver (2010-present). Using cross-sectional data collected during the first year of COVID-19 (April 2020-2021), we developed separate multivariable logistic regression confounder models to examine the independent associations between experiencing increased housing rules and surveillance during COVID-19 on (a) nonfatal overdose, and (b) administration of naloxone for overdose reversal in the last 6 months. RESULTS: Amongst 166 participants, 10.8% reported experiencing a recent non-fatal overdose and 31.3% recently administered naloxone for overdose reversal. 56.6% reported experiencing increased rules and surveillance within their housing during COVID-19. The prevalence of non-fatal overdose and administering naloxone was significantly elevated among those exposed to increased housing rules and surveillance during COVID-19 versus those who were unexposed (83.3% vs. 52.1%; 75.0% vs. 48.2%, respectively). In separate multivariate confounder models, exposure to increased housing rules and surveillance during COVID-19 was independently associated with increased odds of administering naloxone [AOR: 3.66, CI: 1.63-8.21], and marginally associated with non-fatal overdose [AOR: 3.49, CI: 0.92-13.27]. CONCLUSION: Efforts to prioritize the right to safe, adequate and affordable housing must avoid reinforcing an overly coercive reliance on surveillance measures which, while often well-intended, can negatively shape residents' well-being. Furthermore, public health responses to pandemics must include criminalized populations so that measures do not exacerbate overdose risk. Implementation of a regulated drug supply is recommended, alongside housing policies that promote residents' rights, safety, and health.

A surgical odyssey: Conquering a titanic tricuspid vegetation reaching into the superior vena cava - A case report.

INTRODUCTION: Right-sided infective endocarditis, particularly of the tricuspid valve, is rare and challenging to diagnose, often presenting with nonspecific symptoms, and associated with high mortality rates. This case underscores the complexities in managing such conditions and the importance of early diagnosis and multidisciplinary intervention. CASE PRESENTATION: This case study details the medical history of a 34-year-old woman who had a background of intravenous drug abuse. She subsequently developed a fungal tricuspid valve endocarditis, leading to the formation of vegetation that extended into the superior vena cava. The mass measured 15 × 3 cm upon surgical removal. DISCUSSION: Right-sided infective endocarditis is rare, comprising only 5-10 % of cases, with tricuspid valve endocarditis being even rarer. Damage to the endothelium facilitates bacterial attachment, especially in IV drug users, with Staphylococcus aureus being common. Fungal endocarditis is rare but deadly, with high mortality. Diagnosis relies on the modified Duke criteria, including microbiological and imaging evidence. Major complications affect both valvular and systemic areas. Treatment p1rimarily involves IV antibiotics, but surgery is needed for persistent infections or severe complications. CONCLUSION: This case underscores the critical importance of early diagnosis and intervention in managing right-sided infective endocarditis, especially with a fungal pathology and in patients with complex medical histories.

Harm reduction-focused behavioral activation for people who inject drugs: Mixed methods outcomes from a pilot open trial.

INTRODUCTION: People who inject drugs (PWID) experience high rates of mental health problems and drug-related harms. Harm reduction-focused interventions aim to reduce harms associated with drug use and are an important approach for engaging people who are not seeking traditional abstinence-focused treatment. Yet, few studies to date have examined the effectiveness of harm reduction psychosocial treatment for drug use. We evaluated the outcomes of a harm reduction-focused behavioral activation (BA) intervention from pretreatment to a 1-month follow-up. METHODS: A total of N = 23 PWID (65.2 % White; 52.2 % women; mean age 35.4 ±â€¯7.8 years) were recruited from syringe services programs and n = 19 received the intervention via teletherapy. Assessment of study outcome measures occurred at pre- and posttreatment and a one-month follow-up. RESULTS: Results reflected post-intervention increases in behavioral activation and readiness to change drug use, as well as decreases in substance use, depression, and HIV risk behaviors. There were mixed outcomes on substance-related problems with increases at follow-up, possibly reflecting increased problem recognition. CONCLUSIONS: These results suggest initial promise for the harm reduction-focused treatment. Additional research with randomized designs and larger sample sizes is needed, and more intensive treatment may be required to support sustained treatment gains in this population.

Cognitive Intraindividual variability in injection drug use among Hispanic residents of Puerto Rico.

Despite a high prevalence of injection drug use (IDU) in Puerto Rico, little is known about how it affects neuropsychological functioning in this population. Investigations of intra-individual variability (IIV) have alluded to its utility as a potential indicator of neural decline. The purpose of this study was to characterize IIV among Hispanic residents of Puerto Rico who engage in IDU. Injectors and non-injectors completed the Neuropsí Atención y Memoria battery. Measures of IIV were calculated for the overall test battery (OTB), the three battery indices, and three domains of attention, memory, and executive functioning. The injector group showed significantly greater IIV than the non-injector group on all measures (OTB, indices, and individual domains). Additionally, injectors showed significantly higher IIV in the domain of executive functioning compared to other cognitive domains and battery indices. In contrast, non-injectors did not show any significant within-group differences on any IIV measures. The higher performance variability observed in the IDU group suggests a negative influence of IDU on cognition, with executive functioning being more susceptible to these effects. These findings support the need for continued investigations into the clinical application of IIV for diagnostic and prognostic purposes in the Hispanic IDU population.

Candida dubliniensis meningitis in an immunocompetent patient: A case report and review of the literature.

Objective: We present the fifth case of candida dubliniensis meningitis in a young immunocompetent host and suggest extracorporeal membrane oxygenation (ECMO) as a potential risk factor for colonization. Methods: A 22-year-old immunocompetent female presented with a diagnosis of bacterial meningitis. Two years prior, she received ECMO for Covid-19 pneumonia complicated by viral myocarditis & Takutsobo cardiomyopathy. Following discharge, she reported headaches of increasing intensity, all refractory to treatments. Brain magnetic resonance imaging (MRI) was inconclusive. Two weeks prior to her presentation, she was admitted for worsening headaches with cranial nerve VI palsy. Lumbar puncture (LP) revealed white blood cell count (WBC) of 166 cells/µL with neutrophilic predominance and her symptoms progressed, despite 5 days of treatment with broad spectrum antibiotics. All cultures returned negative. Results: At her current presentation, repeat LP revealed 835 WBC/mm3, 225 mg/dL protein, and 4 mg/100 mL glucose. Brain MRI revealed nodular enhancement in the brainstem and communicating hydrocephalus. MRI of the lumbar spine revealed meningeal enhancement. Cerebrospinal fluid (CSF) cultures came back positive for C.dubliniensis. Treatment began with Amphotericin B and Flucytosine. Discussion: When clinical suspicion for fungal meningitis is high, repeate LP and CSF analysis is indicated to establish a definitive diagnosis and begin treatment. Additional studies are needed to confirm risk factors, like ECMO, for the colonization of C.dubliniensis, which likely predisposes individuals to invasive candidiasis.

Factors Influencing the Use and Demand of New Coronavirus Therapy Drugs Among the Adults During COVID-19 in China.

Background: This alteration in the policy of COVID-19 resulted in widespread infections throughout China. Most people only need some antiviral drugs such as lopinavir/ritonavir or Chinese herbal preparations for treatment. In this context, the lack of drug knowledge and inadequate drug availability are evident. This study aims to explore the factors influencing drug use and demand during the COVID-19 epidemic. Methods: This study used quota sampling based on gender, age, and place of residence to perform a cross-sectional survey on a sample of 771 adults. The researchers used chi-square tests to understand differences in drug use and demand across characteristics, and binary logistic regression to analyse the influencing factors. Results: The study revealed that 85.9% of the participants used drugs following the COVID-19 infection. Participants with college and above, (OR=2.49, 95% CI=1.27-4.88) annual personal income between 30,000 and 80,000CNY (OR=2.19, 95% CI=1.35-3.55) and over 80,000CNY (OR=1.96, 95% CI=1.05-3.66) were more knowledgeable about using drugs. Gender, (OR=0.69, 95% CI=0.50-0.95) age, (OR=2.11, 95% CI=1.15-3.88) residence, (OR=1.58, 95% CI=1.06-2.37) chronic disease conditions (OR=0.46, 95% CI=0.27-0.78) and infection symptoms (OR=0.60, 95% CI=0.38-0.93) as factors influencing the need for drug delivery services. (P<0.05). Conclusion: Research has revealed that a significant proportion of infected people in China chose drug treatment during COVID-19. Individuals with severe symptoms use more medication and require more drug delivery and storage. Low-education and low-income populations are lacking in drug knowledge, and older adults with underlying medical conditions are more likely to need drug delivery services. Therefore, governments should prioritize vulnerable groups when formulating drug policies and target drug literacy and guidance. In addition, it is recommended that a drug distribution system be set up within the community so that those in need can have quick and easy access to drugs.

A review of possible biomarkers for opioid tolerance.

Knowledge of opioid tolerance in a deceased person is important for distinguishing between therapeutic and toxic opioid concentrations for that particular individual when interpreting postmortem toxicological results. However, no biomarkers for opioid tolerance are currently available. This review aimed to study the existing literature on mechanisms or changes in signaling pathways related to chronic opioid use, which could be relevant for further studies to identify biomarkers for opioid tolerance. We performed a systematic literature search using the PRISMA 2020 guidelines using the MeSH terms "opioid tolerance AND biomarkers" in PubMed, Embase, WebofScience, and the Cochrane library. A review of the search results yielded seven studies on animal models or humans, identifying and evaluating thirteen possible biomarkers in terms of specificity for changes induced by opioids and other aspects to be considered as potential biomarkers. We evaluated nine potential biomarkers as unlikely to be specific for opioid tolerance, and one had contradictory results in terms of upregulation or downregulation. However, methylation of the promoter region of the µ-opioid receptor gene, increased activity of soluble puromycin-sensitive aminopeptidase, altered miRNA profile, or other multiple component profiling may be interesting to study further as biomarkers for opioid tolerance in forensic postmortem cases.

Deaths of despair-associated mortality rates globally: a 2000-2019 sex-specific disparities analysis.

OBJECTIVES: The aim of this study was to explore sex-specific disparities in rates of deaths of despair across 183 countries from 2000 to 2019. STUDY DESIGN: Secondary analysis of cross-sectional population-level data. METHODS: Data were obtained from the World Health Organization Health Inequality Data Repository. We analysed data on mortality due to alcohol, drug-use disorders, and self-harm (as a proxy for suicide). We calculated the average rate of deaths of despair by year and sex, trends in these rates, and cause-specific mortality trends. We then fitted mixed-effect generalised linear models to compare mortality rates by sex and country. RESULTS: Analyses revealed significant disparities by sex, with a 3.3-fold higher rate among men than among women globally (95% confidence interval: 3.1-3.5, P < 0.001). There was a significant decline in deaths of despair globally and among both sexes during the assessed period (5% per 5 years). Lesotho, Belarus, the US, the Russian Federation, Guyana, and Slovenia ranked among the top 10 countries out of 183 with the highest mortality rates for both sexes. Canada, the Republic of Korea, Belgium, and Finland were countries with the highest mortality rates among women, whereas Ukraine, Lithuania, Mongolia, and Eswatini have the highest rates among men. In the US, 5-year mortality rates increased by 35% for women and 21% for men: drug-use mortality showed a significant increase over time, whereas suicide rates decreased for both sexes in the given country. Additionally, mortality rates from alcohol use decreased among women. CONCLUSIONS: This global analysis shed light on health disparities by sex in deaths of despair, especially concerning trends in the US. It identified countries and groups in need of targeted mental health and substance-use programs. Moreover, the disparities by sex revealed in this analysis suggest that mental health and substance-use interventions and programs may need to be more attentive to sex and/or gender, such as inequitable social norms and restrictive forms of masculinities, which have been shown to be contributing factors to deaths of despair.

Digital Epidemiology of Prescription Drug References on X (Formerly Twitter): Neural Network Topic Modeling and Sentiment Analysis.

BACKGROUND: Data from the social media platform X (formerly Twitter) can provide insights into the types of language that are used when discussing drug use. In past research using latent Dirichlet allocation (LDA), we found that tweets containing "street names" of prescription drugs were difficult to classify due to the similarity to other colloquialisms and lack of clarity over how the terms were used. Conversely, "brand name" references were more amenable to machine-driven categorization. OBJECTIVE: This study sought to use next-generation techniques (beyond LDA) from natural language processing to reprocess X data and automatically cluster groups of tweets into topics to differentiate between street- and brand-name data sets. We also aimed to analyze the differences in emotional valence between the 2 data sets to study the relationship between engagement on social media and sentiment. METHODS: We used the Twitter application programming interface to collect tweets that contained the street and brand name of a prescription drug within the tweet. Using BERTopic in combination with Uniform Manifold Approximation and Projection and k-means, we generated topics for the street-name corpus (n=170,618) and brand-name corpus (n=245,145). Valence Aware Dictionary and Sentiment Reasoner (VADER) scores were used to classify whether tweets within the topics had positive, negative, or neutral sentiments. Two different logistic regression classifiers were used to predict the sentiment label within each corpus. The first model used a tweet's engagement metrics and topic ID to predict the label, while the second model used those features in addition to the top 5000 tweets with the largest term-frequency-inverse document frequency score. RESULTS: Using BERTopic, we identified 40 topics for the street-name data set and 5 topics for the brand-name data set, which we generalized into 8 and 5 topics of discussion, respectively. Four of the general themes of discussion in the brand-name corpus referenced drug use, while 2 themes of discussion in the street-name corpus referenced drug use. From the VADER scores, we found that both corpora were inclined toward positive sentiment. Adding the vectorized tweet text increased the accuracy of our models by around 40% compared with the models that did not incorporate the tweet text in both corpora. CONCLUSIONS: BERTopic was able to classify tweets well. As with LDA, the discussion using brand names was more similar between tweets than the discussion using street names. VADER scores could only be logically applied to the brand-name corpus because of the high prevalence of non-drug-related topics in the street-name data. Brand-name tweets either discussed drugs positively or negatively, with few posts having a neutral emotionality. From our machine learning models, engagement alone was not enough to predict the sentiment label; the added context from the tweets was needed to understand the emotionality of a tweet.

Household Compositions and Substance Use among Young Adults in the U.S.

BACKGROUND: Adults aged 21-29 have the highest past-month prevalence of tobacco, alcohol, and illicit drug use in the U.S. Currently, young adults often delay traditional adulthood milestones (e.g., marriage and childbearing), which may impact their household composition and substance use. METHODS: We examined how the past-month prevalence of eight mutually exclusive substance use outcomes varied by household composition among young adults using the 2016-2019 National Surveys on Drug Use and Health (NSDUH) data. Bivariable and multivariable multinomial logistic regression analyses were applied. RESULTS: Among young adults residing with their children, the most common household composition was residing with children and a spouse/partner (16.6%, 95% CI = 16.5-16.8%). Among those residing without children, common household compositions included residing with parents (22.8%, 95% CI = 22.2-23.4%) and residing only with a spouse/partner (17.9%, 95% CI = 17.6-18.3%). Past-month prevalence of binge alcohol, tobacco, and illicit drug use varied by household composition. Residing only with children and a spouse/partner was associated with a low prevalence of most examined substance use patterns. Across household compositions, those residing solely with unrelated individuals had the highest adjusted prevalence of tobacco, drug, and binge alcohol use (13.8%, 95% CI = 12.5-15.1%). CONCLUSIONS: The prevalence of substance use patterns among U.S. young adults varies by household composition. Those residing solely with unrelated individuals had the highest prevalence of tobacco, binge alcohol, and drug use. The presence of a young adult's own children and a spouse/partner is associated with a lower prevalence of most examined substance use patterns. As household compositions continue to diversify, targeted substance use prevention/treatment strategies may be needed.

Cannabis Use and Associated Risk Behavior Factors among High School Students in Mississippi: Youth Risk Behavior Surveillance System 2021.

Cannabis is the most used illicit drug among youths in the United States. The objectives of this study were to identify the association between cannabis use and other risk behaviors, including suicidality, among high school students. This is a cross-sectional study using the 2021 Mississippi Youth Risk Behavior Surveillance System (YRBS). The 2021 YRBS data sets were combined for this study. The crude odds ratio (OR) and adjusted odds ratio (AOR) with a 95% confidence interval were generated using the survey packages in R to account for weights and the complex sampling design of the YRBS data. Univariate analysis identified seven risky behaviors that were significantly associated with current cannabis use, including carrying weapons on school campuses, suicidal attempts, electronic vapor use, current smoking, current drinking, sexual behaviors, and unsupervised children. In multivariable analysis, after adjusting for gender, race, students' grades, and other risky behaviors, statistically significant variables for cannabis use included current use of electronic vapor, current smoking, current drinking, and sexual behaviors. Cannabis use is evenly burdened between males and females and between all race categories among Mississippi high school students. The identified associations seem to indicate that electronic vapor, tobacco products, and alcohol use could be the forerunners for drug use and should be treated accordingly in drug use prevention programs.
