Clinical Pearls

Bite-sized clinical takeaways from today's literature (sources from May 11 – May 13)

  • Consider ordering pre-treatment structural MRI for patients with treatment-resistant depression to leverage machine learning models that can predict ketamine response and aid in treatment stratification.
  • Utilize NNT, NNH, and LHH metrics when discussing the benefit-risk profile of once-monthly aripiprazole with patients to quantify the trade-offs of long-acting injectable antipsychotics.
  • Monitor for potential pharmacokinetic interactions when prescribing lithium, specifically noting that high-dose vitamin C can alter lithium levels and requires careful management.
  • Recognize that lithium's anti-suicidal effects are mechanistically linked to its modulation of specific brain signals associated with suicide risk, reinforcing its role in high-risk mood disorder management.
  • Screen for insulin resistance in patients with bipolar disorder, as it is linked to gray matter loss and cognitive impairment, potentially indicating a benefit from metabolic interventions such as GLP-1 agonists.
  • Apply consensus guidelines for initiating medications for opioid use disorder (MOUD) within hospital settings to ensure timely and standardized care for patients presenting with acute withdrawal or overdose risk.
  • Consider the emerging evidence for psilocybin in treating chronic suicidal ideation in treatment-resistant depression, acknowledging that early open-label trials show promise for this high-risk population.
  • Evaluate the potential for psilocybin-assisted therapy in patients with cocaine use disorder, as recent trials suggest it may significantly increase cocaine-free days compared to standard care.
  • Be aware of rare but serious adverse events associated with psychiatric medications, including venous thromboembolism from antipsychotics and vasculitis from SSRIs, when monitoring long-term safety.
  • Explore glutamatergic treatment avenues for PTSD, such as fluoxetine-potentiated dextromethorphan protocols, for patients who have not responded to traditional first-line therapies.
