Mental health problems among youth have escalated over the past decade, with increased rates of self-harm, including suicide attempts by ingestion. Social media use has been linked to youth mental health, including "challenges" urging youth to ingest substances for recreational and other purposes. We hypothesized that social media challenges for particular substances would temporally correspond with increased ingestions of these substances. We identified peak Google Trends search times for social media ingestion challenges involving diphenhydramine, laundry pods, nutmeg, and cinnamon, and used data from America's Poison Centers National Poison Data System to plot reported ingestions 3 months before and after peak searches in school-aged children. There were 2,169 individuals in the analysis. Diphenhydramine was the most frequently reported ingestion for misuse/abuse and suicidal purposes (n = 266 and 1,609, respectively). For all ingestions together, 45 percent (n = 979) had a moderate health effect, and 6.35 percent (n = 137) had a major health effect. Time of peak searches corresponded with increased ingestions for each substance. We found a temporal relationship between peak Google Trends searches for ingestion challenges and ingestions of that substance reported to United States poison centers. Compared to misuse/abuse ingestions, most suicidal ingestions peaked 1–2 months later, suggesting a public health opportunity for intervention. This retrospective observational study does not establish causal effect. All data are a result of self-reporting of the exposures, which may lead to a reporting bias. Google Trends is not the only search engine and likely underestimates the true incidence of social media posts. Additional research is needed on the relationship between social media and youth mental health, particularly around "challenges" that place youths' health at risk. There may be opportunities for intervention to decrease medical and mental health sequelae of these challenges. [ABSTRACT FROM AUTHOR]

Childhood and adolescent misuse and abuse exposures remain a serious public health challenge in the United States. This study aimed to describe recent trends and patterns of intentional substance misuse and abuse exposures among school-aged children and adolescents in the United States. This study was a retrospective cohort study of intentional misuse and abuse exposures in children 6 through 18 years reported to the National Poison Data System (NPDS) from January 1, 2000, through December 31, 2020. Demographic trends, reported clinical effects, treatments, management sites, and health outcomes were assessed overall and within four age categories: 6–9, 10–12, 13–15, and 16–18. Between 2000 and 2020, there were 338,727 cases regarding intentional misuse and abuse exposures for children ages 6 through 18 years old. Overall, misuse/abuse ingestions fluctuated over time, with a peak in 2011. The majority of intentional misuse/abuse ingestions occurred in males (58.3%), and more than 80% of all reported exposure cases occurred in youth aged 13 to 18. 32.6% of ingestions resulted in worse than minor clinical outcomes. Older age groups had a greater number of severe medical outcomes compared to younger age groups. Major or life-threatening exposures (including those resulting in death) were more common in males. Overall, deaths were rare (n = 450), 0.1%). Male sex, older age, abuse ingestions, exposure site of a public area or other residence, and multiple ingested substances were other factors associated with increased mortality. Marijuana exposure rates had the highest average monthly increase overall, with the most dramatic rise occurring from 2017 to 2020. Edible marijuana preparations accounted for the highest increase in call rates compared with all other forms of marijuana. With over 330,000 poison center cases reported during the 20-year study period, intentional substance misuse and abuse exposures substantially impact the pediatric population. The substances most commonly misused/abused are more widely available substances such as over-the-counter medications, household products and pharmaceuticals commonly prescribed to youth. Differences in age and sex were evident, with males and adolescents more likely to abuse and misuse substances. Our study describes an upward trend in marijuana misuse/abuse exposures among youth, especially those involving edible products. These findings highlight an ongoing concern about the impact of rapidly evolving cannabis legalization on this vulnerable population. [ABSTRACT FROM AUTHOR]

Although other disciplines have explored sound as more than oral language, music, or noise, educational scholarship exploring everyday soundscapes still has room to grow. In this article, a team of transdisciplinary scholars from education, writing and rhetoric, and ethnomusicology explore new possibilities for sound in research and teaching by examining a cross-course assignment grounded in the sonic experiences of a residential, living-learning college community. Through examining student-produced compositions, we introduce a number of relevant insights into the relationships between space, community, and a pedagogy of aurality. [ABSTRACT FROM AUTHOR]

Objective: Bupropion is often categorized as a newer generation antidepressant and assessed with serotonin reuptake inhibitors as a lower risk than older tricyclic antidepressants (TCAs). The objective of this study was to compare outcomes in adolescent suicide from ingestions between bupropion and TCA medications. Study design: An analysis of the National Poison Data System for exposures coded “suspected suicide” in adolescents (age: 13-19) was undertaken for the years 2013-2016 and included TCAs or bupropion. We compared clinical effects, therapies and medical outcomes. Results: Over the four-year period there were 2253 bupropion and 1496 TCA adolescent suspected suicide calls. There was a significant linear increase in bupropion ingestions over the four years. Across all years, there were on average 189.2 (95% CI: 58.1-320.4; p = .01) more ingestions of bupropion than TCA. When comparing bupropion to a TCA, ingestions of bupropion were significantly more likely to be accompanied by seizure (30.7% vs 3.9%; p < .01), to be admitted (74.8% vs 61.6%; p < .01) and medical outcomes to be coded as a major outcome (19.3% vs 10.0%; p < .01). The number of cases with death or major clinical outcome for both increased over the four-year period. Ingestions of bupropion were less likely to have hypotension (2.7% vs 8.0%; p < .01) and less likely to be intubated (5.6% vs 16.4%; p < .01) as compared to ingestions of TCA. Conclusions: Adolescents who overdose on a single medication in a suicide attempt with bupropion have a statistically significant higher incidence of major outcomes and seizures. The risks of bupropion as a potential means of suicidal gesture by overdose must be considered, and weighed against its benefits and side effect profile when choosing an appropriate agent for the treatment of depression in adolescents.

Purpose . The Canadian Leukemia Studies Group (CLSG) sought to test the safety and efficacy of response-adapted, non-cross resistant chemotherapy in de novo acute myeloid leukemia (AML). The combinations of idarubicin 12 mg/m 2 /d on days 1 – 3 and Ara-C (200 mg/m 2 /d) on days 1 – 7 (IDAC) followed by mitoxantrone 10 mg/m 2 /day, and etoposide 100 mg/m 2 /day, on days 1 – 5 (NOVE) were used according to patient response to induction and consolidation. Patients and methods . In this multi-centre open-label phase II study, 140 patients up to age 80 were given induction with IDAC. Patients were entered between March 1993 and August 1995. If patients had persistent blasts at day 14 or on recovery, they were given NOVE. As consolidation, patients achieving complete remission (CR) with IDAC were given 1 further cycle of IDAC and 1 cycle of NOVE. Patients achieving CR after NOVE were given 2 further cycles of NOVE. Results . 76% of all patients achieved remission after IDAC +/- NOVE, 81% in patients aged ≤60 years and 67% in patients aged >60. Overall, induction mortality was 11% and toxicity was similar to other cooperative group studies. Median follow-up was 104.0 months with 95% CI: (100.0, 105.2). Median overall survival (OS) in responding patients ≤60 was not reached: of the 79 responders ≤60, 35 died. The median disease free survival (DFS) in these responding patients was 22.7 (14.9, na) months. Median OS and DFS in responding patients >60 was 10.0 (7.3, 15.2) months and 7.5 (6.2, 15.2) months, respectively. Conclusion . The results of this trial are very encouraging and suggest that there may be long-term benefit to this method. On the basis of these results, a randomized phase III trial has been performed.
