Evaluating culturally and linguistically integrated care for Latinx adults with mental and substance use disorders.

Objective: To evaluate changes in health and health care utilization outcomes for Latinx adults with substance use and mental disorders receiving integrated behavioral and primary health care.Design: Study sample included enrollees who completed baseline, 6-month and 12-month assessments (n = 107). Study outcomes were depression symptom severity, anxiety symptom severity, illicit drug use, emergency department utilization and homelessness status. Pre-post analyses were conducted using paired t-test and McNemar test to examine changes in study outcomes. Multivariable regression model estimated through generalized estimating equations explored the influence of the intervention on study outcomes. Results were presented in adjusted odds ratios (AOR) and 95% confidence intervals (CI).Results: Participants were less likely to report depressive symptoms (AOR: 0.496, 95%CI: 0.296-0.832), less likely to report anxiety symptoms (AOR: 0.539, 95%CI: 0.329-0.884), and less likely to experience homelessness (AOR: 0.556, 95%CI: 0.328-0.943) at 6-month assessment compared to baseline. Participants were also less likely to report depressive symptoms (AOR: 0.378, 95%CI: 0.209-0.684), less likely to report anxiety symptoms (AOR: 0.471, 95%CI: 0.270-0.821), less likely to experience homelessness (AOR: 0.333, 95%CI: 0.189-0.587), and less likely to utilize the emergency department in the past 30 days (AOR: 0.397, 95%CI: 0.188-0.837) at 12-month assessment compared to baseline.Conclusions: Integrating culturally responsive behavioral and primary health care services is critical for addressing the needs of Latinx adults with mental and substance use disorders, and other chronic diseases. This initiative has the potential to reduce disparities in access to and engagement in care for Latinx adults.

Time-forward speech intelligibility in time-reversed rooms.

The effects of time-reversed room acoustics on word recognition abilities were examined using virtual auditory space techniques, which allowed for temporal manipulation of the room acoustics independent of the speech source signals. Two acoustical conditions were tested: one in which room acoustics were simulated in a realistic time-forward fashion and one in which the room acoustics were reversed in time, causing reverberation and acoustic reflections to precede the direct-path energy. Significant decreases in speech intelligibility--from 89% on average to less than 25%--were observed between the time-forward and time-reversed rooms. This result is not predictable using standard methods for estimating speech intelligibility based on the modulation transfer function of the room. It may instead be due to increased degradation of onset information in the speech signals when room acoustics are time-reversed.
