Clinical Pearls

Bite-sized clinical takeaways from today's literature (sources from Oct 08 – Apr 20)

  • Prescribe aripiprazole or quetiapine over olanzapine or risperidone for elderly patients with dementia to reduce all-cause mortality risk, particularly those with type 2 diabetes.
  • Monitor dementia patients closely for cerebrovascular and major cardiovascular events within the first four weeks of starting risperidone due to elevated stroke risk.
  • Consider intravenous ketamine as a treatment option for severe suicidal crises given recent regulatory approvals in France and ongoing efficacy data under anesthesia.
  • Evaluate antipsychotic-induced glucose dysregulation through its mechanistic link to impaired pancreatic beta-cell insulin secretion when managing metabolic side effects.
  • Incorporate the Parent-report Nationwide Quality of Life Scale (P-NQLS) into routine assessments for children aged 6-18 to distinguish quality of life deficits from symptom severity.
  • Investigate elevated soluble CD27 in cerebrospinal fluid as a biomarker for severe psychiatric patients with comorbid autoimmune diseases and active neuroinflammation.
  • Be aware that the FDA has issued a Class II recall for a specific lot of Viatris 3 mg extended-release Xanax due to failed dissolution specifications that may cause inconsistent drug release.
  • Review the role of GABAergic neuroactive steroids, specifically brexanolone, when treating peripartum depression given their pathophysiological relevance.
  • Recognize that astrocytic α7nAChRs are the critical mediators of pro-cognitive effects via D-serine/NMDAR signaling, explaining why prior trials targeting neuronal receptors failed.
  • Consider NUAK1 variants as a potential mechanistic link to synaptic structural defects when evaluating autism-associated phenotypes involving dendritic spine maturation.
