Empowering understanding: navigating consent to ketamine treatment in adolescent mental health.

The rising prevalence of mental health disorders in adolescents, compounded by treatment resistance, underscores the need for innovative interventions. Ketamine, recognized for its rapid antidepressant and anti-suicidal effects in adults, has recently emerged as a potential treatment for adolescents with treatment-resistant depression and suicidality. This paper aims to highlight key elements of the informed consent process, including obtaining parental consent and adolescent assent, and discussing the nature of ketamine treatment, its benefits, and potential risks. Obtaining informed consent for ketamine treatment in this demographic poses unique challenges. During the informed consent process, clinicians should balance an adolescent's growing autonomy with parental consent and address the distinct features of treatment, including ketamine's potential to induce psychedelic-like effects. Additionally, clinicians should highlight the "off-label" use in this population and the uncertainty inherent to treatment at this time, including the lack of data on repeated ketamine exposure on the developing brain. This paper also addresses challenging scenarios related to informed consent for this treatment, such as instances when parents are willing to consent but the adolescent refuses. Alternative treatment strategies such as transcranial magnetic stimulation (TMS) and electroconvulsive therapy (ECT) are also considered. In conclusion, while an emerging body of evidence suggests that ketamine shows potential for the acute treatment of adolescents with severe depression and suicidality, adherence to informed consent principles is paramount to ensure best clinical practices and uphold ethical standards amidst the current landscape of ongoing research.

The therapeutic use and efficacy of ketamine in alcohol use disorder and alcohol withdrawal syndrome: a scoping review.

Introduction: Alcohol use disorder (AUD) is the most prevalent substance use disorder (SUD) globally. In 2019, AUD affected 14.5 million Americans and contributed to 95,000 deaths, with an annual cost exceeding 250 billion dollars. Current treatment options for AUD have moderate therapeutic effects and high relapse rates. Recent investigations have demonstrated the potential efficacy of intravenous ketamine infusions to increase alcohol abstinence and may be a safe adjunct to the existing alcohol withdrawal syndrome (AWS) management strategies. Methods: We followed Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines to conduct a scoping review of two databases (PubMed and Google Scholar) for peer-reviewed manuscripts describing the use of ketamine in AUD and AWS. Studies that evaluated the use of ketamine in AUD and AWS in humans were included. We excluded studies that examined laboratory animals, described alternative uses of ketamine, or discussed other treatments of AUD and AWS. Results: We identified 204 research studies in our database search. Of these, 10 articles demonstrated the use of ketamine in AUD or AWS in humans. Seven studies investigated the use of ketamine in AUD and three studies described its use in AWS. Ketamine used in AUD was beneficial in reducing cravings, alcohol consumption and longer abstinence rates when compared to treatment as usual. In AWS, ketamine was used as an adjunct to standard benzodiazepine therapy during severe refractory AWS and at signs of delirium tremens. Adjunctive use of ketamine demonstrated earlier resolution of delirium tremens and AWS, reduced ICU stay, and lowered likelihood of intubation. Oversedation, headache, hypertension, and euphoria were the documented adverse effects after ketamine administration for AUD and AWS. Conclusion: The use of sub-dissociative doses of ketamine for the treatment of AUD and AWS is promising but more definitive evidence of its efficacy and safety is required before recommending it for broader clinical use.

Lurasidone Malabsorption Following Bariatric Surgery: A Case Report.

A significant segment of the United States adult population is obese. Bariatric surgery is one approach to weight loss when nonsurgical efforts have failed. In individuals with a body mass index ≥50, gastric reduction with duodenal switch is more effective than gastric bypass. More than half of bariatric surgery candidates report a history of mental illness and more than one third were taking at least one psychotropic medication at the time of surgery. Thus, the impact of surgery on absorption of psychiatric medications should be considered. Lurasidone, a second-generation antipsychotic used to treat schizophrenia and bipolar disorder, is recommended to be taken with food of at least 350 calories. We describe the case of a patient with incomplete response to lurasidone therapy in the year following a duodenal switch procedure. This case raises concern about the effect that the duodenal switch procedure may have on lurasidone absorption.

Urolithiasis associated with indinavir in a patient with spinal cord injury.

OBJECTIVE: To report a case of indinavir-induced urolithiasis, and the greater risk of this occurrence in individuals with spinal cord injury (SCI) who require fluid restriction for an intermittent catheterization program (ICP). METHODS: Case report. RESULTS: A 38-year-old man with a T4 ASIA A SCI (according to the American Spinal Injury Association classification scale) and human immunodeficiency virus (HIV) infection was using an ICP and taking indinavir (a protease inhibitor) as part of his antiviral regimen. Cystoscopy was performed to rule out recurrent urethral condylomata. He was found to have a bladder stone measuring 0.5 cm x 0.5 cm x 0.3 cm, which, on analysis, was composed of indinavir (100% exterior, 90% interior). The bladder stone was removed under direct visualization. The plain abdominal radiograph did not reveal any stones. CONCLUSION: Indinavir is a frequently used drug for the treatment of HIV that has the potential to induce urinary lithiasis. This is particularly problematic for individuals with SCI who are on fluid restriction and an ICP. Therefore, cystoscopy and monitoring for indinavir-induced urolithiasis should be undertaken in individuals with SCI who are taking indinavir. Considerations include switching to a different protease inhibitor or choosing an entirely new HIV drug cocktail with less potential for urolithiasis.
