To examine older adults' cannabidiol (CBD) use and its associations with cannabis use and physical/mental health and other substance use problems. Using the 2022 National Survey on Drug Use and Health (N = 10,516 respondents age 50+), we fitted generalized linear models (GLM) with Poisson and log link using CBD as the dependent variable in the 50-64 and the 65+ age groups. In the 50-64 age group, 18.3% and 18.0% reported past-year CBD and cannabis, respectively, use. In the 65+ age group, the percentages were 14.3% and 8.0%. GLM results showed significant positive associations with both medical and non-medical cannabis use in both age groups. CBD use was positively associated with physical/mental health and illicit drug use problems in the 50-64 age group and with disordered psychotherapeutic drug use in the 65+ age group. Minoritized older adults had a lower likelihood of CBD use. CBD use is common, more so than cannabis especially in the 65+ age group and positively correlated with both medical and nonmedical cannabis use. Research is needed to examine therapeutic benefits and negative effects of CBD use in late life. Public health education is needed for growing numbers of older-adult CBD users.

Despite known contraindications, benzodiazepines are frequently prescribed for older adults. This study utilizes poison control center data on benzodiazepine-involved cases aged 50 and above to compare the characteristics of suspected suicide attempt with other intentional misuse cases. We also examined associations of major medical outcomes (major effect/death) with demographic characteristics and other co-used substances in each group. The study employed data from the America's Poison Center National Poison Data System from 2015-2022. Descriptive statistics and binary logistic regression models were used. Of the benzodiazepine-poisoning cases of intentional misuse (n = 93,245), 85 percent were suicide attempts and 15 percent were other intentional misuses. Reports to poisons centers showed a decline from 2019-2022 when compared to 2015-2016. However, the likelihood of a reported suicide attempt, compared to other intentional misuse, was greater in 2019-2022 compared to 2015-2016 and among those who co-used antidepressants, anxiolytics, atypical antipsychotics, other benzodiazepines, other analgesics, anticonvulsants, and alcohol. The odds of major effect/death in both groups were also greater in 2019-2022, with suicide attempt cases in advanced ages showing higher odds. The co-use of antidepressants, prescription opioids, atypical antipsychotics, anticonvulsants, and other analgesics were associated with a higher likelihood of major effect/death in both exposure groups. For instance, adjusted odds ratios for co-used prescription opioids were 2.20 (95 percent confidence intervals: 2.09-2.31) among suicide attempt cases and 3.51 (95 percent confidence intervals: 3.10-3.97) among other intentional misuse cases. Healthcare providers need to screen for suicidal ideation among benzodiazepine users, with special attention to an increased risk of suicide attempt among those who co-use antidepressants and opioids and to decreasing adverse outcomes in all misuse cases. Assessments of underlying mental health and substance use problems and medication regimens to minimize polypharmacy and drug interactions are needed to reduce adverse outcomes. Though the numbers of benzodiazepine-involved suicide attempt and other intentional misuse cases reported to United States poison centers decreased in recent years, the likelihood of major medical effect/death among these cases have increased.

To examine correlates of the changes in technology use among older adults and the associations of depression/anxiety symptoms with technology use changes. We used the 2019-2021 U.S. National Health and Aging Trends Study (N = 3,063; age 70+). We fitted multinomial logistic regression models to examine: (1) correlates of never use and discontinued use versus use of email/texting and the internet during the 3-year study period; and (2) associations of past-month depression/anxiety symptoms in 2021 with use and discontinued use versus never use of email/texting and social network site (SNS). The findings show age, socioeconomic, and health barriers to technology use. Email/texting and SNS use in 2021, compared to never use in all 3 years, was associated with a lower likelihood of moderate/severe depression/anxiety symptoms in 2021 (RRR = 0.54, 95% CI = 0.37-0.81 for email/texting use; RRR = 0.56, 95% CI = 0.33-0.97 for SNS use). Video calls with family/friends were not associated with depression/anxiety symptoms. The findings expand the existing knowledge base regarding potential impact of technology use on mental health beyond the early months of the COVID-19 pandemic. More concerted efforts are warranted to help older adults' technology uptake and continued use and to promote mental health benefits of technology use.

Analyzing the 2021 National Survey on Drug Use and Health data with generalized linear models, we examined: (1) COVID pandemic-related and other correlates of mental health treatment use and unmet perceived treatment need among U.S. adults who experienced serious suicidal thoughts (N = 3,177); and (2) correlates of self-reported reasons for not receiving treatment. We found that 61% used any mental health treatment, and 48% of users and 37% of nonusers reported perceived treatment need. Significant correlates of treatment use were demographic factors, insurance, major depressive disorder, and illicit drug use disorder. Significant correlates of perceived treatment need were age 18–34, some college education, and major depressive episode. Perceived negative effect of the COVID pandemic on mental health was a significant factor for both treatment use and perceived need. The most frequent reasons for not getting treatment were the cost of treatment or lack of insurance and stigma-related concerns.

Cryptococcal meningitis is a life-threatening fungal infection of the central nervous system. It primarily affects immunocompromised individuals, particularly those with advanced HIV/AIDS, but can occur in people of all ages. Risk factors include solid organ transplantation, hematological malignancies, immunosuppressive medications, and primary immunodeficiency disorders. We describe a case of a 68-year-old male with atypical risk factors for cryptococcal meningitis who presented acutely delirious with a negative diagnostic workup aside from a positive cerebrospinal fluid (CSF) meningitis screen reporting Cryptococcus neoformans/gattii. While the rate of lumbar puncture (LP) in the ED has drastically decreased over the years, we emphasize the importance of considering its diagnostic value in emergency department settings in patients with atypical presentations.

Introduction: Given the increasing adult use of amphetamine and methylphenidate and their high misuse potential, we examined suspected suicide attempts and other intentional misuse and medical outcomes and their associations with co-used other substances among amphetamine and methylphenidate exposure cases aged 50+. Methods: Using the 2015–2021 U.S. National Poison Data System (N = 7701 amphetamine and/or methylphenidate cases), we fit two generalized linear models for a Poisson distribution with a log link function, with suspected suicide attempt versus intentional misuse and major medical effect/death versus other outcomes as the dependent variables. Results: Of all amphetamine/methylphenidate exposure cases, suspected suicide attempts and intentional misuse were 28.4% and 13.2%, respectively. Benzodiazepine use was associated with a higher likelihood, but any illicit drug use was associated with a lower likelihood of suspected suicide attempts compared to intentional misuse. The type of stimulant involved (amphetamine or methylphenidate) was not significant. The co-use of antidepressants (IRR = 1.43, 95% CI = 1.16–1.76), prescription opioids (IRR = 1.48, 95% CI = 1.21–1.81), drugs for cardiovascular disease (IRR = 1.51, 95% CI = 1.20–1.90), antipsychotics (IRR = 1.26, 95% CI = 1.02–1.55), or illicit drugs (IRR = 2.40, 95% CI = 1.82–3.15) was associated with a higher likelihood of major effect/death. Conclusions: Suspected suicide attempts or intentional misuse accounted for more than 40% of amphetamine or methylphenidate exposure cases aged 50+. The higher likelihood of major effect/death in cases involving antidepressants, antipsychotics, and cardiovascular disease drugs also suggests the confounding effects of comorbid mental and physical health problems. Careful monitoring of those who were prescribed amphetamine or methylphenidate and use other substances is needed.
