Cannabis use and medication nonadherence in bipolar disorder: A nationwide inpatient sample database analysis.

BACKGROUND: Medication nonadherence among bipolar disorder (BD) is often linked with comorbid substance use disorders. This study aims to investigate cannabis use disorder (CUD) association with medication noncompliance in hospitalized BD patients. METHODS: Using data on 266,303 BD hospitalizations between 2010 and 2014 from the US Nationwide Inpatient Sample database, we obtained medication noncompliance rates stratified by demographics and CUD. Logistic regression was used to evaluate factors associated with medication noncompliance. RESULTS: Overall mean age, the prevalence of CUD, and medication nonadherence were 41.58 (± 0.11) years, 15.0% and 16.1%, respectively. There were 56.6% females in the overall population. There was a significant difference in the characteristics of those in the medication nonadherence vs adherence groups, including age, sex, race, comorbid substance use, income, insurance type, hospital region, and hospital teaching status (p < 0.001). After adjusting for other variables using multivariate analysis, there remained a statistically significant association of medication nonadherence in BD hospitalization and CUD (OR 1.42, 95% CI 1.36-1.48). LIMITATION: Confounding multiple substance use could not be accounted for, and the retrospective nature of the database which includes only inpatients is prone to possible selection and reporting bias. CONCLUSION: CUD statistically predicts increased rates of medication nonadherence among patients with BD. Given the possible association of CUD with medication nonadherence among BD patients, collaborative work between general adult psychiatry and addiction services is imperative in improving the management outcome of patients with BD and comorbid CUD.

Does Cocaine Use Increase Medication Noncompliance in Bipolar Disorders? A United States Nationwide Inpatient Cross-Sectional Study.

Introduction Medication noncompliance among bipolar disorder (BD) is often linked with comorbid substance use disorders. This study aims to investigate cocaine use (CU) association with medication noncompliance in hospitalized BD patients. Methods Using data on 266,303 BD hospitalizations between 2010-2014 from the US Nationwide Inpatient Sample database, we obtained medication noncompliance rates stratified by demographics and cocaine use. Logistic regression was used to evaluate factors associated with medication noncompliance. Results Overall mean age, the prevalence of CU, and medication noncompliance were 41.58 (+0.11) years, 8.34%, and 16.08%, respectively. More than half of BD patients with comorbid CU were between 40-64 years (54.4%), while more male patients with BD were in the CU group (53.9%). With univariable logistic regression, CU (odds ratio [OR]: 1.77, 95% CI: 1.66-1.88) increased the odds of medication noncompliance among BD patients, and after adjusting for other variables there was sustained increased odds (adjusted odds ratio [aOR]: 1.40, 95% CI: 1.32-1.50). Conclusion This study showed that CU is associated with medication noncompliance among hospitalized BD patients. This highlights the importance of addressing CU among BD patients. Given the possible association of CU with medication noncompliance among BD patients, collaborative work between general adult psychiatry and addiction services is imperative in improving the management outcome of BD patients with comorbid CU.

The Effectiveness of Electroconvulsive Therapy on Catatonia in a Case of Anti-N-Methyl-D-Aspartate (Anti-NMDA) Receptor Encephalitis.

Catatonia is a symptom seen in a variety of neuropsychiatric conditions, including anti-N-Methyl D-aspartate receptor (NMDAR) encephalitis. When associated with anti-NMDAR encephalitis, catatonia is resistant to standard therapy. However, electroconvulsive therapy (ECT) has shown promising success in management. This case report presents a 25-year-old African American female who presented to the emergency room with nervousness, sweating, insomnia, and visual and auditory hallucinations. She was treated symptomatically for anxiety but returned to the hospital after she continued to experience worsening symptoms. Her anxiety worsened, and she became more agitated, warranting an extensive workup, including magnetic resonance imaging (MRI) and electroencephalogram (EEG), which showed normal findings. She also had an anti-NMDA receptor antibodies titer done, which showed a positive titer result. She was treated with intravenous steroids, intravenous immunoglobulin G (IgG), plasma exchange, and rituximab, which did not improve her symptoms, and she was discharged home after a prolonged hospital stay. On follow-up visits, she reported worsening confusion, aggression, and suicidal behaviors. The patient was readmitted, during which she experienced catatonia and psychiatric symptoms, and her anti-NMDAR titer had increased to 1:1280. Further treatments with intravenous steroids, intravenous IgG, plasma exchange, and rituximab, including haloperidol and clonazepam, failed to improve her condition. However, her condition improved remarkably following treatment with 12 rounds of ECT. No randomized control trial has been done to demonstrate the effectiveness of ECT in the treatment of anti-NMDAR encephalitis despite various reports of the effectiveness of this treatment modality. This case report adds to the growing clinical evidence in support of the use of ECT in anti-NMDAR encephalitis patients with catatonia. ECT can be incorporated as standard protocol in the treatment of catatonia and associated psychiatric symptoms when managing a patient with anti-NMDAR encephalitis associated with catatonic features.

Diabetes Mellitus with Chronic Complications in Relation to Carotid Endarterectomy and Carotid Artery Stenting Outcomes.

BACKGROUND: Carotid endarterectomy and carotid artery stenting are effective treatment procedures for carotid artery stenosis. Although diabetes mellitus is highly prevalent among patients undergoing these revascularization procedures, few studies have examined their impact on periprocedural outcomes. OBJECTIVES: The study aimed to determine whether perioperative outcomes among patients undergoing carotid artery stenting and carotid endarterectomy varied depending on the presence of diabetes with or without chronic complications. METHODS: We examined adults aged 45 and above hospitalized between 2007 and 2011 in U.S. hospitals who underwent carotid artery revascularization procedures. We used data from the Healthcare Cost and Utilization Project's Nationwide Inpatient Sample and evaluated the influence of diabetes with or without chronic complications on outcomes. RESULTS: Among patients receiving carotid artery stenting, diabetic patients with chronic complications had significantly increased odds of acute kidney injury (odds ratio [OR]: 3.17, 95% confidence interval [CI]: 2.31-4.35) and longer hospital stay (ß: 1.98, 95% CI: 1.58-2.38) compared with nondiabetic patients. Diabetic patients with chronic complications receiving carotid endarterectomy experienced increased odds of myocardial infarction (OR: 1.12, 95% CI: .90-1.40), stroke (OR: 1.29, 95% CI: .97-1.72), perioperative infection (OR: 2.45, 95% CI: 1.29-4.65), mortality (OR: 1.48, 95% CI: 1.01-2.16), and longer hospital stay (ß (days): 2.05, 95% CI: 1.90-2.20) compared with nondiabetic patients. No significant increased odds of perioperative outcomes were observed among diabetic patients without chronic complications. CONCLUSIONS: Uncomplicated diabetes did not appear to convey a higher odds of perioperative outcomes among patients undergoing revascularization. However, the presence of diabetes with chronic complications is an important risk factor in the carotid endarterectomy category.
