Clinical Pearls

Bite-sized clinical takeaways from today's literature (sources from Aug 26 – May 12)

  • Monitor height and weight Z-scores in children and adolescents on methylphenidate due to evidence of small but significant growth suppression.
  • Counsel patients starting lumateperone for treatment-resistant depression that while it reduces symptoms, high discontinuation rates due to side effects are common.
  • Consider rTMS targeting the dorsolateral prefrontal cortex as a non-pharmacologic alternative for smoking cessation in patients who cannot tolerate or have failed standard therapies.
  • Utilize pre-treatment structural MRI data to predict ketamine response in treatment-resistant depression, as machine learning models show moderate accuracy for biomarker-informed stratification.
  • Be aware of the ongoing debate regarding treatment-emergent mania in pediatric populations when initiating antidepressants, and monitor for this adverse effect closely.
  • Prescribe antidopaminergic or muscarinic antipsychotics for acute schizophrenia based on network meta-analysis data comparing their respective efficacy and tolerability profiles.
  • Recognize that GLP-1 agonists may offer therapeutic potential for alcohol use disorder, particularly in patients with obesity who exhibit exacerbated metabolic alterations and cravings.
  • Monitor for potential lithium pharmacokinetic interactions when prescribing lithium alongside high-dose vitamin C, as case reports highlight this specific adverse event.
  • Consider the emerging evidence for a single dose of psilocybin combined with psychotherapy to increase cocaine-free days in patients with cocaine use disorder.
  • Evaluate the potential of an oral protocol combining fluoxetine and dextromethorphan for rapid symptom improvement in trauma-related disorders, leveraging glutamatergic mechanisms.
