External contamination is a well-recognized limitation of hair analysis for drugs of abuse like methylamphetamine (MA), and there are no guidelines regarding the analysis of specific metabolites of MA to assist interpretation. We developed an analytical method to detect MA, amphetamine (AMP), and para-hydroxy-methylamphetamine (p-OH-MA) in hair and present their concentrations among a cohort of deceased persons positive for MA in blood (n = 63). Hair samples (≤ 3 cm) were washed with dichloromethane and water prior to extraction using a methanolic micro-pulverization. The reconstituted hair extracts were separated on a UCT Selectra® Aqueous C18 HPLC Column (100 × 2.1 mm, 3 μm) by gradient elution and detected using a Sciex Triple Quad 6500+ system. Validation was satisfactory, and the lower limits of quantitation were 0.01 ng/mg for MA and AMP and 0.001 ng/mg for p-OH-MA. The median hair concentrations of MA, AMP, and p-OH-MA were 13 ng/mg (range = 0.015-49; n = 51), 1.1 ng/mg (range = 0.018-44; n = 60), and 0.020 ng/mg (range = 0.0012-0.38, n = 62), respectively. These concentrations in hair were strongly positively correlated (r = .7202 to .8641, p < .001), suggesting similar modes of incorporation. Moreover, the wash/hair ratios were indicative of external contamination, especially among the soiled group of hair samples. Therefore, further studies are necessary to determine concentrations of p-OH-MA in living MA users and confirm if this metabolite constitutes a potential marker of MA consumption.

OBJECTIVE
This study aims to analyze the relationship between reproductive tract microecological changes, metabolic differences, and pregnancy outcomes at different time points in the frozen-thawed embryo transfer cycle while patients are undergoing hormone replacement therapy, which will be a breakthrough point for improving outcomes.
METHODS
A total of 20 women undergoing frozen-thawed single blastocyst transfer for the first time at the Reproductive Medicine Center of Fujian Maternal and Child Health Hospital between July 2022 and January 2023 were recruited for this study. Their vaginal and cervical secretions were collected for 16S rRNA sequencing and non-targeted metabolomics analysis on days 2-5 of menstruation, day 7 after estrogen replacement therapy started, the day when progesterone was added, and the day of transplantation. The subjects were divided into different groups according to their clinical pregnancy status and the sequencing results were analyzed using bioinformatics methods.
RESULTS
1) The alpha-diversity index of the vaginal and cervical microbiota was higher on days 2-5 of menstruation (<0.01), but did not differ significantly on day 7 after oral estrogen replacement therapy started, the day of progesterone administration, and the day of transplantation (≥0.1). 2) Both the pregnant group and the non-pregnant group showed a variety of microorganisms and metabolites with significant differences in the lower reproductive tract at different time points. 3) Microbial analysis at different time points showed that there were significant differences in vaginal flora, including , , , , , , , , , and in the pregnant group (<0.05). 4) Metabolite analysis at different time points showed that there were significant differences in 3-hydroxybenzoic acid, linatine, (R)-amphetamine, hydroxychloroquine, and L-altarate in the vaginal secretions of the pregnant group (<0.05), and that there were significant differences in isocitric acid, quassin, citrinin, and 12(R)-HETE in the cervical secretions (<0.05). 5) Metabolite analysis at different time points showed that, in the non-pregnant group, there were significant differences in linatine, decanoyl-L-carnitine, aspartame, sphingosine, and hydroxychloroquine in the vaginal secretions (<0.05), and the isocitric acid, quassin, ctrinin, and 12(R)-HETE in the cervical secretions (<0.05). 6) Combined microbiome and metabolomics analysis showed that certain metabolites were significantly associated with microbial communities, especially .
CONCLUSIONS
Significant differences in the microbiota genera and metabolites at different time points were found during the frozen-embryo transfer cycle of hormone replacement therapy, which may be used as potential biomarkers to predict pregnancy outcomes of embryo transfer.

Review
From 2011 to 2023, substance use increased by 23% worldwide. Given that substance use initiation is highest during adolescence, it is crucial to identify amenable correlates of substance use prevention [e.g. health literacy (HL)], which, if embedded in interventions, may improve uptake and outcomes. Hence, this study conducted a scoping review to answer the question: What is known from the existing literature about the relationship between HL and substance use correlates and behaviors in adolescents? Five electronic databases and the bibliography of review articles were searched and a total of 1770 records were identified. After removing duplicates and engaging in three levels of screening to identify studies that included adolescents ≤ 25 years old and assessed the relationship between general HL (vs. behavior/disease-specific health knowledge) and substance use behaviors and correlates, 16 studies were retained. Studies assessed alcohol-related (n = 11), tobacco-related (n = 12), electronic vapor product use-related (n = 4), cannabis-related (n = 1), and amphetamines/methamphetamines-related (n = 1) outcomes. Studies spanned Africa, Asia, Europe, and North and Central America. Most studies included substance use as an outcome and found an inverse relationship between HL and use. Few studies examined substance use correlates (e.g. risk perception). There were no longitudinal or intervention studies. This review highlighted that the topic of adolescent HL and its relationship with substance use remains inadequately researched. Notable gaps for future studies include intervention and longitudinal designs, expansion of outcomes (e.g. more studies on marijuana, prescription drug misuse, vaping, substance use-related correlates), and examining HL as a mediator or moderator of substance use and its correlates.

Stimulants are the first-line pharmacological treatment for attention deficit hyperactivity disorder (ADHD). We present the unique case of a patient who developed a chewing compulsion when taking mixed amphetamine salts (MAS). A 32-year-old female patient with a past medical history of gastroesophageal reflux disease (GERD), gastroparesis, and migraines was seen for initial psychiatric assessment due to concerns for irritability. She was diagnosed with post-traumatic stress disorder (PTSD); generalized anxiety disorder; ADHD, inattentive type; and unspecified bipolar disorder. Lamotrigine was started and titrated to 25mg twice per day, with improved mood stability. MAS immediate-release (IR) was started at 2.5mg and titrated to 5mg daily for ADHD. She then experienced an uncontrollable urge to chew, finding relief when chewing on a child's teething necklace, which provided satisfaction and a reduction in anxiety. She denied jaw tightness or teeth grinding. The dose of MAS IR was reduced to 2.5mg daily with improvement in symptoms and later increased again to 5mg daily, which she was then able to tolerate. Stereotyped biting behaviors have been observed in rats with the use of amphetamines, and the onset of compulsive behavior has emerged in children with the use of dextroamphetamine. However, this is the first known case of compulsive chewing or biting movements reported in humans with MAS use. This case highlights the need to assess patients for adverse events, such as compulsive biting and chewing movements or other oral facial stereotypies, after commencement of stimulants, including MAS.

BACKGROUND
Substance use and cardiovascular (CV) events are increasing among pregnant women in the United States, but association between substance use in pregnancy and CV events remains unknown.
OBJECTIVES
The purpose of this study was to examine the association between substance use and acute CV events in pregnancy.
METHODS
We identified all women with a delivery hospitalization between 2004 and 2018 in the Nationwide Inpatient Sample, stratified on the presence or absence of substance use. The primary outcome was any acute CV event, defined as the presence of: acute myocardial infarction, stroke, arrhythmia, endocarditis, acute cardiomyopathy or heart failure, or cardiac arrest. Secondary outcomes were individual acute CV events, major adverse cardiac events, and maternal mortality. The association between substance use and outcomes were examined using multivariable logistical regression.
RESULTS
A total of 60,014,368 delivery hospitalizations occurred from 2004 to 2018, with substance use complicating 955,531 (1.6%) deliveries. Substance use was independently associated with CV events (adjusted odds ratio [aOR]: 1.61; 95% CI: 1.53-1.70; < 0.001), major adverse cardiac events (aOR: 1.53; 95% CI: 1.46-1.61; < 0.001), and maternal mortality (aOR: 2.65; 95% CI: 2.15-3.25; < 0.001) during delivery hospitalization. All individual substances had an increased association with CV events; however, amphetamine/methamphetamine had the strongest association (aOR: 2.71; 95% CI: 2.35-3.12; < 0.001). All substances other than cocaine and cannabis had a significant association with maternal death.
CONCLUSIONS
Substance use has a strong association with acute CV events and maternal mortality during hospitalization for delivery and women with substance use warrant increased surveillance for CV events during this time.

Brain can a useful specimen for toxicology testing as it is a protected and isolated organ with lower metabolic activity than other tissues, but there is currently no published data supporting the stability of stimulant drugs in prepared brain homogenates. Brain homogenates were evaluated to determine the stability of the following stimulant drugs: amphetamine, benzoylecgonine, bupropion, cocaethylene, cocaine, ephedrine, methylenedioxyamphetamine, methylenedioxymethamphetamine, methamphetamine, and phentermine. Four different homogenates were prepared at a 1:4 dilution with deionized water and fortified at 500 ng/mL of: cocaine without sodium fluoride, cocaine with 1% sodium fluoride, stimulant drugs other than cocaine without sodium fluoride, and stimulant drugs other than cocaine with 1% sodium fluoride. The fortified homogenates were aliquoted into 13x100 mm screw cap tubes and stored at room temperature (~20 °C), refrigerated (2-8 °C), or frozen (< -5 °C) and analyzed in triplicate on Days 0, 1, 3, 7, 14, 30, 60, and 90. Analytes were considered stable as long as the difference in analyte/internal standard response ratio from Day 0 was less than 20% and the peaks met qualitative acceptance criteria. All analytes were stable for up to 90 days when stored frozen with or without sodium fluoride and had variable stability at all other evaluated conditions.

Journal of Medical Case Reports Jun 2024We present a unique case of rhinolalia as the first recognizable sign of spontaneous pneumomediastinum and surgical emphysema following drug use.
BACKGROUND
We present a unique case of rhinolalia as the first recognizable sign of spontaneous pneumomediastinum and surgical emphysema following drug use.
CASE PRESENTATION
This case presents a 17-year-old white male experiencing rhinolalia following ecstasy ingestion at a rave. Subsequent chest X-ray revealed extensive surgical emphysema, along with a continuous diaphragm sign indicative of pneumomediastinum. Computed tomography confirmed the diagnosis. The patient was managed conservatively with strict monitoring and 6 hourly electrocardiograms. Follow-up computed tomography on day 3 showed resolution of pneumomediastinum and surgical emphysema, and the patient was safely discharged. Notably, the patient experienced a temporary rhinolalia during the acute phase, which resolved spontaneously as his condition improved.
CONCLUSIONS
This case underscores the importance of considering spontaneous pneumomediastinum and surgical emphysema in the differential diagnosis of young individuals presenting with acute symptoms after drug use.

INTRODUCTION
Injecting methamphetamine poses significant health risks, but little is known about how methamphetamine injectors filter their injection preparations and experience related health concerns.
METHODS
A chain-referral sample of Indigenous people who inject methamphetamine ( = 30) was recruited and semistructured interviews were conducted to collect information on filtration practices and health concerns.
RESULTS
Filtration of the injection preparation was described by 53% of injectors. Elevated levels of concern for kidney disease, cancer and heart disease were observed among those who filtered their preparations (ranging from 50 to 56.3%). Concern about liver disease was the most frequent concern among those who filtered their preparations (62.5%) and was elevated in comparison to those who did not use filters (7.1%). Grouped logistic regression revealed a positive association between filtration of the injection preparation and overall health concerns expressed by injectors, after adjusting for gender and age. The marginal posterior distribution of the adjusted odds ratio for filtration of the injection preparation had a posterior median = 35.7, and 95% HPD interval = (5.1, 512.4).
DISCUSSION
Results illustrate a positive relationship between filtration of the injection preparation and health concerns among Indigenous people who inject methamphetamine. This likely reflects the use of filtration to reduce harms, and further research is needed to understand the full scope of prevention that may be associated with filtration of methamphetamine injection preparations.

Meta-Analysis
Classic psychedelics and MDMA have a colorful history of recreational use, and both have recently been re-evaluated as tools for the treatment of psychiatric disorders. Several studies have been carried out to assess potential long-term effects of a regular use on cognition, delivering distinct results for psychedelics and MDMA. However, to date knowledge is scarce on cognitive performance during acute effects of those substances. In this systematic review and meta-analysis, we investigate how cognitive functioning is affected by psychedelics and MDMA during the acute drug effects and the sub-acute ("afterglow") window. Our quantitative analyses suggest that acute cognitive performance is differentially affected by psychedelics when compared to MDMA: psychedelics impair attention and executive function, whereas MDMA primarily affects memory, leaving executive functions and attention unaffected. Our qualitative analyses reveal that executive functioning and creativity may be increased during a window of at least 24 h after the acute effects of psychedelics have subsided, whereas no such results have been observed for MDMA. Our findings may contribute to inform recommendations on harm reduction for recreational settings and to help fostering differential approaches for the use of psychedelics and MDMA within a therapeutic framework.
