History of obstructive sleep apnea associated with incident cognitive impairment in white but not black individuals in a US national cohort study.

BACKGROUND: We sought to determine if risk for obstructive sleep apnea (OSA), a history of OSA, and/or treatment of OSA has a different association with incident cognitive impairment or cognitive decline in Black individuals and White individuals. METHODS: To determine whether the risk for OSA, a history of OSA, and/or treatment of OSA has a different association with incident cognitive impairment or cognitive decline in Black individuals and White individuals; data from the REasons for Geographic and Racial Differences in Stroke (REGARDS) was used. Participants that completed the sleep questionnaire module, had baseline cognitive assessment, and at least one cognitive assessment during follow-up were included. Risk of OSA was determined based on Berlin Sleep Questionnaire. History of sleep apnea was determined based on structured interview questions. Optimally treated OSA was defined as treated sleep apnea as at least 4 h of continuous positive airway pressure use per night for ≥5 nights per week. RESULTS: In 19,017 participants stratified by race, White participants with history of OSA were 1.62 times more likely to have incident cognitive impairment compared to White participants without history of OSA after adjusting for demographic characteristics, history, and lifestyle factors (OR = 1.62, 95% CI = 1.05-2.50, p-value = 0.03). This relationship was not seen in Black participants (OR = 0.92, 95% CI = 0.60-1.43, p-value = 0.72). DISCUSSION: A previous diagnosis of OSA is associated with incident cognitive impairment in White Americans but not Black Americans. Further investigations are required to determine the mechanism for this difference.

Integrated Treatment Group Curriculum for People with Serious Mental Health Conditions Who Use Substances.

Without proper treatment, people with co-occurring mental health and substance use problems are at great risk for poor outcomes and high treatment costs in multiple domains. Intermediary organizations can provide support to programs implementing integrated treatment and other evidence-based practices; this includes developing practical tools for programs built to encourage fidelity to a particular practice. In this paper, we describe a group curriculum workbook designed to help practitioners provide integrated treatment with fidelity and a pilot learning collaborative to evaluate whether this workbook is a helpful tool for programs to support people with serious mental health conditions and substance use in identifying and achieving personal goals. Results of the pilot found that nearly all participants demonstrated progress with respect to their identified goals, and group facilitators reported that the workbook was easy to use, that participants enjoyed the material, and that they intended to continue offering the group as part of their regular programming.

MicroRNA expression within neuronal-derived small extracellular vesicles in frontotemporal degeneration.

MicroRNAs (miRNAs) are small non-coding RNA that are powerful regulators of gene expression and can affect the expression of hundreds of genes. miRNAs can be packed in small extracellular vesicles (SEV) and released into the extracellular space by neurons and microglia to act locally as well as pass through the blood-brain barrier and act systemically. We sought to understand the differences in neuronal SEV miRNA expression between frontotemporal dementia (FTD), Alzheimer's disease (AD), and healthy aging. Plasma was obtained from FTD, AD, and healthy aging participants that were matched based on age, sex, and race/ethnicity. Additionally, a subset of participants also provided paired cerebrospinal fluid samples to compare neuronal SEV miRNAs in plasma and cerebrospinal fluid. Neuronal SEV were isolated using differential ultracentrifugation and antibody conjugated Dynabeads® for the neuronal surface marker, L1CAM. RNA sequencing was performed. 12 FTD, 11 with AD, and 10 healthy aging participants were enrolled in the study. In FTD, SEV miRNA-181c was downregulated compared to healthy controls. In AD, miRNA-122 and miRNA-3591 were downregulated compared to those in healthy controls and FTD. Using an FDR <0.2, only miRNA-21-5p was found to have increased expression in the cerebrospinal fluid compared to plasma in a group of AD and FTD participants. SEV miRNA-181c is significantly downregulated in FTD compared to healthy controls and may mediate its effects through microglial-directed neuroinflammation and interaction with TAR DNA-binding protein 43 (TDP-43) based on pathway analysis. Additionally, the FOXO and Hippo pathways may be important mediators of FTD, based on pathway analysis. Lastly, because only one SEV miRNA was differentially expressed between the plasma and cerebrospinal fluid in paired samples, plasma represents an appropriate biofluid for studying neuronal SEV miRNA.

Self- Evaluation Tool to Support Implementation of Treatment for Tobacco Use Disorder in Behavioral Health Programs.

Tobacco use in people with behavioral health conditions remain two to three times higher than the general population causing premature death and impacting recovery negatively across several domains. Intermediary organizations can provide practical tools, training, and technical assistance to help programs improve capacity to treat tobacco use. This report describes the construction and application of the Tobacco Integration Self-Evaluation Tool (TiSET) for behavioral health programs, a 20-item scale inspired by the DDCMHT and additional content from the Facility Tobacco Policy and Treatment Practices Self-Evaluation tool that one of the study authors (JW) used previously with addiction treatment programs. Completing the TiSET is an important step for behavioral health programs to evaluate their ability to effectively treat people that use tobacco. An important next step is to use those results to facilitate a quality improvement process. We include large agency example illustrating how the TiSET can be applied in real-world practice.

Applying Motivational Interviewing Strategies to Enhance Organizational Readiness and Facilitate Implementation Efforts.

Motivational interviewing (MI) is an empirically supported clinical method to help individuals make behavioral changes to achieve a personal goal. Through a set of specific techniques, MI helps individuals mobilize their own intrinsic values and goals to explore and resolve ambivalence about change. This article examines how MI-informed approaches can be applied to help staff adopt new evidence-based practices in organizational settings. Although the implementation science literature offers strategies for implementing new practices within organizations, leaders of quality improvement initiatives often encounter ambivalence about change among staff. Implementation approaches that require staff to make substantial changes may be facilitated by drawing from MI strategies. These include building a sense of collaboration from the beginning, eliciting "change talk," and addressing any ambivalence encountered. Motivational interviewing techniques may be particularly helpful in working with those in a stage of precontemplation (who have yet to see a reason for change) and those who are contemplating change (who see that a problem exists but are ambivalent about change). This article provides examples of how an MI-informed approach can be applied to help facilitate change in staff within organizations that are implementing quality improvement initiatives. These techniques are illustrated using a representative scenario.

Using distance technologies to facilitate a learning collaborative to implement stagewise treatment.

OBJECTIVE: This report describes experiences and outcomes of an online learning collaborative focused on implementation of stagewise treatment. METHODS: Eleven participating programs convened online monthly for a year. Between meetings, program staff created an implementation plan and programs collected performance indicator data, including assessment of staff knowledge of integrated treatment for people with co-occurring disorders, whether a person's current stage of treatment was documented in his or her chart, and whether the treatments were appropriate for the stage of treatment. Descriptive statistics were used to characterize performance indicators and feedback. Wilcoxon matched-pairs signed-rank tests examined changes in performance indicators over time. RESULTS: Program staff generally demonstrated significant improvements in performance indicators over time and rated the distance learning collaborative favorably. CONCLUSIONS: Distance learning collaboratives can be structured to provide opportunities for program staff to interact and learn from one another and to implement and sustain changes.
