Genome-wide transcriptomics of the amygdala reveals similar oligodendrocyte-related responses to acute and chronic alcohol drinking in female mice.

Repeated excessive alcohol consumption is a risk factor for alcohol use disorder (AUD). Although AUD has been more common in men than women, women develop more severe behavioral and physical impairments. However, relatively few new therapeutics targeting development of AUD, particularly in women, have been validated. To gain a better understanding of molecular mechanisms underlying alcohol intake, we conducted a genome-wide RNA-sequencing analysis in female mice exposed to different modes (acute vs chronic) of ethanol drinking. We focused on transcriptional profiles in the amygdala including the central and basolateral subnuclei, brain areas previously implicated in alcohol drinking and seeking. Surprisingly, we found that both drinking modes triggered similar changes in gene expression and canonical pathways, including upregulation of ribosome-related/translational pathways and myelination pathways, and downregulation of chromatin binding and histone modification. In addition, analyses of hub genes and upstream regulatory pathways revealed that voluntary ethanol consumption affects epigenetic changes via histone deacetylation pathways, oligodendrocyte and myelin function, and the oligodendrocyte-related transcription factor, Sox17. Furthermore, a viral vector-assisted knockdown of Sox17 gene expression in the amygdala prevented a gradual increase in alcohol consumption during repeated accesses. Overall, these results suggest that the expression of oligodendrocyte-related genes in the amygdala is sensitive to voluntary alcohol drinking in female mice. These findings suggest potential molecular targets for future therapeutic approaches to prevent the development of AUD, due to repeated excessive alcohol consumption, particularly in women.

Health status, difficulties, and desired health information and services for veterans with traumatic brain injuries and their caregivers: A qualitative investigation.

Traumatic brain injury (TBI) is considered the signature injury among military service member and Veterans who served in Operation Iraqi Freedom and Operation Enduring Freedom with over 360,000 individuals sustaining a first-time TBI in the military. These service members and Veterans, and their caregiver(s), must navigate multiple health systems and find experts across many fields of expertise to recover and optimize functionality. Twenty-two individuals, 10 caregivers of Veterans with TBI, 12 Veterans with TBI, participated in semi-structured interviews. Responses were coded using NVivo. Participants from both groups reported difficulties finding community supportive services (support groups) in local communities. Most participants identified the need for an advocate or point-person to help guide them to needed services and provide ongoing support in the post-acute health care recovery phase. Caregivers and Veterans desired a more personalized recovery plan from their medical professionals. When describing their ideal health information and services model most identified interactivity and twenty-four-hour availability as essential components. To provide Veterans and caregivers with optimal support and resources to navigate a complicated health services system, advocates and personalized care plans are needed. Future research should examine the feasibility and cost-effectiveness of these services.

A qualitative study examining methods of accessing and identifying research relevant to clinical practice among rehabilitation clinicians.

PURPOSE: Research examining the utilization of evidence-based practice (EBP) specifically among rehabilitation clinicians is limited. The objective of this study was to examine how various rehabilitative clinicians including physical therapists, occupational therapists, rehabilitation counselors, and physiatrists are gaining access to literature and whether they are able to implement the available research into practice. METHODS: A total of 21 total clinicians were interviewed via telephone. Using NVivo, a qualitative analysis of the responses was performed. RESULTS: There were similarities found with respect to the information-seeking behaviors and translation of research across the different clinician types. Lack of time was reported to be a barrier for both access to literature and implementation of research across all clinician types. The majority of clinicians who reported having difficulty with utilizing the published literature indicated that the literature was not applicable to their practice, the research was not specific enough to be put into practice, or the research found was too outdated to be relevant. In addition, having a supportive work environment aided in the search and utilization of research through providing resources central to assisting clinicians in gaining access to health information. CONCLUSION: Our study identified several barriers that affect EBP for rehabilitation clinicians. The findings suggest the need for researchers to ensure that their work is applicable and specific to clinical practice for implementation to occur.

Identifying and Understanding the Health Information Experiences and Preferences of Caregivers of Individuals With Either Traumatic Brain Injury, Spinal Cord Injury, or Burn Injury: A Qualitative Investigation.

BACKGROUND: In order to meet the challenges of caring for an injured person, caregivers need access to health information. However, caregivers often feel that they lack adequate information. Previous studies of caregivers have primarily focused on either their time and emotional burdens or their health outcomes, but the information needs of caregivers have not been thoroughly investigated. OBJECTIVE: The purpose of this investigation was to identify the preferred sources of health information for caregivers supporting individuals with injuries and to explore how access to this information could be improved. METHODS: A total of 32 caregivers participated in semistructured interviews, which were used in order to develop a more in-depth understanding of these caregivers' information needs. Digital audio recordings of the interviews were used for analysis purposes. These audio recordings were analyzed using a thematic analysis or qualitative content analysis. All of participant's interviews were then coded using the qualitative analysis program, Nvivo 10 for Mac (QSR International). RESULTS: The caregivers endorsed similar behaviors and preferences when seeking and accessing health information. Medical professionals were the preferred source of information, while ease of access made the Internet the most common avenue to obtain information. The challenges faced by participants were frequently a result of limited support. In describing an ideal health system, participants expressed interest in a comprehensive care website offering support network resources, instructive services about the injury and caregiving, and injury-specific materials. CONCLUSIONS: According to the participants, an ideal health information system would include a comprehensive care website that offered supportive network resources, instructive services about the injury and caregiving, and materials specific to the type of patient injury.
