Objective: To illustrate the toxicosurveillance role of the Emerging Drugs Network of Australia - Victoria (EDNAV) project in informing timely harm minimisation interventions. Methods: Utilisation of an ethics approved clinical registry storing de-identified clinical and analytical data on Victorian ED illicit drugrelated presentations. Results: In April 2022, six adults presented to hospital with varying levels of sedation, following the use of counterfeit benzodiazepines. Comprehensive toxicological analysis identified five separate novel benzodiazepines within blood samples from each patient. A public 'Drug Alert' was subsequently issued, and local emergency physicians were notified. Conclusion: Toxicosurveillance projects, such as EDNAV, are critical to the continued monitoring and reporting of illicit substance use in the community. [ABSTRACT FROM AUTHOR]

Objective: To compare the efficacy of intravenous chlorpromazine versus intravenous prochlorperazine for the treatment of acute migraine in adults presenting to the emergency department (ED). Background: Migraine is a common, incapacitating neurological condition. Although chlorpromazine and prochlorperazine are known to be safe, efficacious treatments for migraine, they have never been directly compared. Design: We performed a prospective, randomized, double‐blind clinical trial at a tertiary hospital in Melbourne, Australia. Adults aged 18–65 years, who presented with migraine, were eligible for recruitment. Sixty‐six patients were randomized to either chlorpromazine 12.5 mg or prochlorperazine 12.5 mg, both infused in 500 ml of sodium chloride 0.9% over 30 min. Headache severity score, nausea severity score, and the presence of photophobia and phonophobia were assessed at 0, 30, 60, and 120 min. Adverse effects and the need for rescue therapy were recorded. The primary outcome was a reduction in headache severity score from baseline at 60 min post‐commencement of the study medicine infusion. Results: Sixty‐five patients were included in the analysis. There was a median reduction in headache severity score at 60 min of 3.0 (interquartile range 1.0–4.0) in the chlorpromazine arm versus 2.0 (1.0–4.0) in the prochlorperazine arm (median difference −0.5 (95% confidence interval, −1.9 to 0.9)). We saw no evidence of a difference in secondary outcomes at 30, 60, or 120 min. Side effects were reported in 16/32 (50%) patients in the chlorpromazine group versus 7/33 (21%) in the prochlorperazine group (p = 0.020). Rescue therapy was required in 7/32 (22%) patients in the chlorpromazine group versus 12/33 (36%) in the prochlorperazine group (p = 0.277). Conclusions: Both chlorpromazine and prochlorperazine are efficacious treatments for acute migraine in adult patients presenting to the ED. This trial found no evidence of superiority of either agent over the other. Caution should be used when prescribing these medicines in the borderline hypotensive patient; in that circumstance, prochlorperazine should be preferentially used. [ABSTRACT FROM AUTHOR]

Previous research has highlighted the important role of parental emotions in parent-child interactions and child development. The present study presents the Parental Feelings Inventory (PFI), a new rating scale designed to assess parental emotions within the parenting role. The PFI presents emotion adjectives and asks parents to indicate the degree to which they experience that emotion in their role as parents. This study investigates the factor analytic structure and psychometric properties of this scale in a sample of parents with 3-year-old children. Participants included 149 mothers and 107 fathers of preschool-age children. The results provide support for a three-factor solution (Angry, Happy, and Anxious/Sad). This scale demonstrated good reliability and correlated with other measures of parent and child functioning. These findings provide support for the overall utility of the PFI as a measure of emotional experiences in the parenting role. [ABSTRACT FROM AUTHOR]

The emergence of benzodiazepine-type new psychoactive substances (NPSs) are a growing international public health concern, with increasing detections in drug seizures and clinical and coronial casework. This study describes the patterns and nature of benzodiazepine-type NPS detections extracted from the Emerging Drugs Network of Australia – Victoria (EDNAV) project, to better characterise benzodiazepine-type NPS exposures within an Australian context. EDNAV is a state-wide illicit drug toxicosurveillance project collecting data from patients presenting to an emergency department with illicit drug-related toxicity. Patient blood samples were screened for illicit, pharmaceutical and NPSs utilising liquid chromatography-tandem mass spectrometry. Demographic, clinical, and analytical data was extracted from the centralised registry for cases with an analytical confirmation of a benzodiazepine-type NPS(s) between September 2020–August 2022. A benzodiazepine-type NPS was detected in 16.5 % of the EDNAV cohort (n = 183/1112). Benzodiazepine-type NPS positive patients were predominately male (69.4 %, n = 127), with a median age of 24 (range 16-68) years. Twelve different benzodiazepine-type NPSs were detected over the two-year period, most commonly clonazolam (n = 82, 44.8 %), etizolam (n = 62, 33.9 %), clobromazolam (n = 43, 23.5 %), flualprazolam (n = 42, 23.0 %), and phenazepam (n = 31, 16.9 %). Two or more benzodiazepine-type NPSs were detected in 47.0 % of benzodiazepine-type NPS positive patients. No patient referenced the use of a benzodiazepine-type NPS by name or reported the possibility of heterogenous product content. Non-prescription benzodiazepine use may be an emerging concern in Australia, particularly amongst young males. The large variety of benzodiazepine-type NPS combinations suggest that consumers may not be aware of product heterogeneity upon purchase or use. Continued monitoring efforts are paramount to inform harm reduction opportunities. [ABSTRACT FROM AUTHOR]
