Longitudinal assessment of Indiana dentists' participation in Medicaid before and after expansion.

Background: Although Medicaid expansion aims to eliminate financial barriers to health care for low-income people in the United States, health care accessibility cannot be guaranteed without clinicians who provide health care to Medicaid recipients. This study examined the characteristics of Indiana dentists that are associated with the likelihood of participating in Medicaid after expansion in 2015.

Methods: This study included Indiana-licensed dentists who renewed their licenses in 2018 and provided supplemental data elements related to demographics, education and training, and professional characteristics.

A controlled trial of quetiapine XR coadministration treatment of SSRI-resistant panic disorder.

Background: Open-label quetiapine coadministration with SSRI therapy, in a diagnostically mixed sample of comorbid anxiety patients, offered additional anxiolytic benefit. Therefore, we designed the following controlled trial to confirm these findings in a comorbid, SSRI-resistant, panic disorder (PD) patient sample.

Methods: This was a single-site, double-blind, placebo-controlled (PLAC), randomized, parallel group (2 groups), 8-week, quetiapine extended release (XR) coadministration trial.

Double-blind, placebo-controlled, pilot trial of paliperidone augmentation in serotonin reuptake inhibitor-resistant obsessive-compulsive disorder.

Objective: This pilot study explored the efficacy and tolerability of paliperidone augmentation of serotonin reuptake inhibitors (SRIs) in adults with treatment-resistant obsessive-compulsive disorder (OCD).

Method: Thirty-four patients aged 24-67 years (mean = 43.7 years, SD = 11.

Increased resting-state functional connectivity between the anterior cingulate cortex and the precuneus in panic disorder: resting-state connectivity in panic disorder.

Background: The structural and functional abnormalities of the anterior cingulate cortex (ACC) have been reported in panic disorder (PD). Patients with PD have shown decreased gamma-aminobutyric acid (GABA) concentration in the ACC. The GABA concentration in the ACC was found to be associated with default mode network (DMN) activity in normal human subjects.

Decreased GABA levels in anterior cingulate cortex/medial prefrontal cortex in panic disorder.

Changes of various brain metabolites including γ-aminobutyric acid (GABA), measured by 1H-magnetic resonance spectroscopy (MRS), have been reported in panic disorder (PD). Deficits in GABA have been implicated in the pathophysiology of PD. Furthermore, it has been suggested that cortical metabolite changes in PD are familial.
