Abstract Introduction Perinatal depression is a serious and highly prevalent medical condition in the USA. Nearly 85% of individuals with perinatal depression go untreated, leading to significant morbidity and mortality. There is an urgent need to develop and advance safe and effective treatments for perinatal depression. Transcranial magnetic stimulation is an established intervention for depression in non-pregnant individuals yet is not well studied in perinatal depression. Case presentation A 33-year-old pregnant Latina female presented with severe, recurrent, treatment-resistant depression and suicidal ideation. The patient had previously trialed psychotherapy, multiple antidepressants, and mood stabilizers and had achieved remission with lithium prior to pregnancy. Due to pregnancy and fetal safety concerns, the patient discontinued lithium and consequently suffered progressive worsening of perinatal depression. At 24 weeks gestation and after additional failed medication trials, a prolonged course of transcranial magnetic stimulation was initiated. Following 46 transcranial magnetic stimulation treatments over 9 weeks using two protocol types (repetitive transcranial magnetic stimulation and intermittent theta burst stimulation), she achieved near-remission of perinatal depression and resolution of suicidal ideation. There were no identified maternal or fetal adverse events at 6 weeks post-delivery. Conclusion To our knowledge, this is the first published case of a pregnant individual with perinatal depression who received and tolerated a prolonged transcranial magnetic stimulation course with two distinct protocols (repetitive transcranial magnetic stimulation and intermittent theta burst stimulation) with clinically significant response. Transcranial magnetic stimulation is a well-tolerated and effective intervention that warrants further investigation for use in treatment-resistant perinatal depression.

Background and Hypothesis Clozapine is an effective yet underutilized treatment for treatment‐resistant schizophrenia spectrum disorders. This study aimed to identify factors affecting clozapine prescribing patterns among patients with treatment‐resistant schizophrenia and schizoaffective disorder at an academic medical center. Study Design This retrospective combined cohort and case‐control study examined demographic, socioeconomic, medical and psychiatric characteristics to determine predictors of clozapine initiation. Eligible patients had a diagnosis of schizophrenia or schizoaffective disorder with at least two prior antipsychotic trials and were admitted to a University of Utah inpatient psychiatric facility (1/2014–3/2021). Patients who did and did not receive clozapine during the index hospitalization were compared in cohort and case‐control study arms. Study Results Twelve percent (59/477) of the cohort received clozapine during the index admission. Among the cohort (n = 477), Black patients were twice as likely to receive clozapine than White and Hispanic patients (OR 2.18, 95% CI 1.20–3.97, p = 0.008). In the case‐control analysis, patients with a greater number of previous psychiatric admissions (OR 1.14, p = 0.079) and antipsychotic trials (OR 1.40, p = 0.038) had greater odds of receiving clozapine. Homelessness was identified as a predictor against clozapine use (OR 2.77, p = 0.014). Conclusions This is the first study to identify homelessness as a predictor against clozapine use, which raises important clinical and ethical considerations. Our findings also add to the literature on clozapine prescribing discrepancies among ethnic‐minority patients. Overall, clozapine remains underutilized as the gold‐standard treatment for treatment‐resistant schizophrenia‐spectrum disorders, reinforcing a need to improve evidence‐based prescribing.
