Successful bilateral electroconvulsive therapy in a patient with a seizure disorder taking levetiracetam, lorazepam, and zonisamide: A case report.
Electroconvulsive therapy (ECT) may be considered for treatment of severe, treatment-resistant, and emergent depression associated with MDD or bipolar disorder. Patients with epilepsy usually take medications that raise the seizure threshold, which poses challenges during ECT. We report a 66-year-old male with epilepsy taking levetiracetam extended-release (XR), lorazepam, and zonisamide requiring ECT for severe MDD. After literature review, the XR form of levetiracetam was changed to higher doses of the immediate-release (IR) formulation, and zonisamide was discontinued 2 days prior to ECT in the hospital and was resumed when the patient underwent outpatient continuation ECT. The patient was treated to remission after receiving 8 acute bilateral ECT treatments before being transitioned to continuation ECT. We provide a brief review of medication management of antiepileptic drugs and other medications that increase the seizure threshold during ECT. To our knowledge, this is the first reported case describing the management of levetiracetam, lorazepam, and zonisamide concomitantly during ECT. Our case suggests that utilizing the IR formulation of levetiracetam, administering the evening dose early the day prior to the procedure, and temporarily discontinuing zonisamide prior to bilateral ECT is effective for the treatment of severe MDD while maintaining seizure prophylaxis
Possible inhibitory effects of terbinafine on aripiprazole metabolism: Two case reports
Aripiprazole, an atypical antipsychotic, is a metabolic substrate for cytochrome P450 (CYP)3A4 and 2D6. Terbinafine, an antifungal agent used for onychomycosis, is a CYP2D6 inhibitor and could theoretically reduce the metabolism of aripiprazole. However, there are no published reports describing this interaction. We present 2 female patients hospitalized in a psychiatric unit who were both taking aripiprazole 15 mg daily and terbinafine 250 mg daily prior to admission. The first patient was a 58-year-old female who was prescribed aripiprazole and terbinafine concomitantly for approximately 5 months prior to admission. A commercial pharmacogenetic testing platform classified this patient as a normal metabolizer for CYP3A4 and 2D6. The first patient's serum trough aripiprazole concentration at steady-state concentration (Css) was 207.5 ng/mL. The second patient was a 43-year-old female who was taking aripiprazole and terbinafine concomitantly for approximately 2 weeks prior to admission who had a Css aripiprazole concentration of 278.9 ng/mL. Aripiprazole has a wide therapeutic range (100 to 350 ng/mL) and a reference dose-related drug concentration of 11.7 (mean)±5.6 (SD) ng/mL/mg/d. Our patients had Css aripiprazole concentrations 18% and 59% higher than guideline-supported dose-related drug concentrations. Through the use of therapeutic drug monitoring, pharmacogenetic data, electronic pharmaceutical claims data, and the Drug Interaction Probability Scale, we suggest terbinafine possibly increases aripiprazole concentrations 18% to 59%. Further reports are needed to confirm these findings prior to using this information in clinical practice

Comparison of Outcomes of antibiotic Drugs and Appendectomy (CODA) trial: a protocol for the pragmatic randomised study of appendicitis treatment.
INTRODUCTION: Several European studies suggest that some patients with appendicitis can be treated safely with antibiotics. A portion of patients eventually undergo appendectomy within a year, with 10%-15% failing to respond in the initial period and a similar additional proportion with suspected recurrent episodes requiring appendectomy. Nearly all patients with appendicitis in the USA are still treated with surgery. A rigorous comparative effectiveness trial in the USA that is sufficiently large and pragmatic to incorporate usual variations in care and measures the patient experience is needed to determine whether antibiotics are as good as appendectomy.
OBJECTIVES: The Comparing Outcomes of Antibiotic Drugs and Appendectomy (CODA) trial for acute appendicitis aims to determine whether the antibiotic treatment strategy is non-inferior to appendectomy.
METHODS/ANALYSIS: CODA is a randomised, pragmatic non-inferiority trial that aims to recruit 1552 English-speaking and Spanish-speaking adults with imaging-confirmed appendicitis. Participants are randomised to appendectomy or 10 days of antibiotics (including an option for complete outpatient therapy). A total of 500 patients who decline randomisation but consent to follow-up will be included in a parallel observational cohort. The primary analytic outcome is quality of life (measured by the EuroQol five dimension index) at 4 weeks. Clinical adverse events, rate of eventual appendectomy, decisional regret, return to work/school, work productivity and healthcare utilisation will be compared. Planned exploratory analyses will identify subpopulations that may have a differential risk of eventual appendectomy in the antibiotic treatment arm.
ETHICS AND DISSEMINATION: This trial was approved by the University of Washington\u27s Human Subjects Division. Results from this trial will be presented in international conferences and published in peer-reviewed journals.

The Association between Clinician's Global Assessment of Functioning and Serum 25 (OH) Vitamin D Levels in Adult Veterans with Schizophrenia Residing in a Long-term Care Facility
Abstract Vitamin D is an important hormone that is well known for its role in musculoskeletal health. Data supports a role for vitamin D within the central nervous system as a neuroprotective and dopamine modulating steroid. It is hypothesized that vitamin D deficiency plays a role in the development of schizophrenia. There is increasing interest as to if serum vitamin D levels have an effect on disease state severity and functioning in patients with schizophrenia. The objective of this study was to identify an association between the physician's global assessment of functioning (GAF) rating and serum 25(OH)D levels. A retrospective chart review was conducted using an electronic medical record. A total of 21 patients were included in this study. A negative association between serum 25(OH)D levels and GAF rating was found. Patients with serum 25(OH)D levels of ≤35 ng/mL were found to have an average GAF rating of 38 while patients with serum 25(OH)D levels of >35 ng/mL had an average GAF rating of 28 (p=0.041). No statistically significant difference between groups could be found when patients with diagnosis of dementia were removed from both groups. A total of 71% of all patients were determined to have sufficient vitamin D levels. Though it was found that patients with lower serum 25(OH)D levels had higher GAF ratings, a true inverse relationship cannot be accepted due to several limitations
