New Brunswick HEARS: outcomes of a community-delivered hearing intervention adapted for older adults in Atlantic Canada.

Objective: To assess acceptability and benefit of a community-based hearing intervention delivered at no cost to lower-income older adults with untreated hearing loss in New Brunswick, Canada.

Design: Mixed method pre-post intervention study investigating aspects of communication function and social support at baseline and three months post-intervention.

Study Sample: 124 of 175 independent-living older adults screened at the study site and in local community centres in low-income neighbourhoods were recruited into the study.

Evaluating the impact of a national geriatric mental health ECHO educational program on healthcare providers' practice.

Project Extension for Community Healthcare Outcomes (ECHO) enables healthcare providers to share knowledge and best practices via telementoring. The ECHO model builds provider capacity and improves care for patients with a variety of health conditions. This study describes a Canada-wide National ECHO pilot project in the area of geriatric mental health and reports on the program's impact on providers' care practices.

Impact of on Physical and Psychosocial Outcomes.

Dance for older adults is increasingly being used to support health and well-being. While dance may be enjoyable for many, understanding its benefits for those with limited physical and cognitive abilities may provide further support for how dance may be used in these contexts. This was a study of , a dance program with remotely streamed sessions.

ECHO Care of the Elderly: Innovative Learning to Build Capacity in Long-term Care.

Background: Older adults are entering long-term care (LTC) homes with more complex care needs than in previous decades, resulting in demands on point-of-care staff to provide additional and specialty services. This study evaluated whether Project ECHO (Extension for Community Healthcare Outcomes) Care of the Elderly Long-Term Care (COE-LTC)-a case-based online education program-is an effective capacity-building program among interprofessional health-care teams caring for LTC residents.

Methods: A mixed-method, pre-and-post study comprised of satisfaction, knowledge, and self-efficacy surveys and exploration of experience via semi-structured interviews.

Building Long-Term Care Staff Capacity During COVID-19 Through Just-in-Time Learning: Evaluation of a Modified ECHO Model.

Objectives: The onset of the COVID-19 pandemic significantly challenged the capacity of long-term care (LTC) homes in Canada, resulting in new, pressing priorities for leaders and health care providers (HCPs) in the care and safety of LTC residents. This study aimed to determine whether Project ECHO (Extension for Community Healthcare Outcomes) Care of the Elderly Long-Term Care (COE-LTC): COVID-19, a virtual education program, was effective at delivering just-in-time learning and best practices to support LTC teams and residents during the pandemic.

Design: Mixed methods evaluation.

Negative correlation between grey matter in the hippocampus and caudate nucleus in healthy aging.

Neurobiological changes that occur with aging include a reduction in function and volume of the hippocampus. These changes were associated with corresponding memory deficits in navigation tasks. However, navigation can involve different strategies that are dependent on the hippocampus and caudate nucleus.

Molecular imaging of serotonin degeneration in mild cognitive impairment.

Neuropathological and neuroimaging studies have consistently demonstrated degeneration of monoamine systems, especially the serotonin system, in normal aging and Alzheimer's disease. The evidence for degeneration of the serotonin system in mild cognitive impairment is limited. Thus, the goal of the present study was to measure the serotonin transporter in vivo in mild cognitive impairment and healthy controls.

Association between serotonin denervation and resting-state functional connectivity in mild cognitive impairment.

Resting-state functional connectivity alterations have been demonstrated in Alzheimer's disease (AD) and mild cognitive impairment (MCI) before the observation of AD neuropathology, but mechanisms driving these changes are not well understood. Serotonin neurodegeneration has been observed in MCI and AD and is associated with cognitive deficits and neuropsychiatric symptoms, but the role of the serotonin system in relation to brain network dysfunction has not been a major focus of investigation. The current study investigated the relationship between serotonin transporter availability (SERT; measured using positron emission tomography) and brain network functional connectivity (measured using resting-state functional MRI) in 20 participants with MCI and 21 healthy controls.

Deep brain stimulation of the subcallosal cingulate for treatment-refractory anorexia nervosa: 1 year follow-up of an open-label trial.

Background: Anorexia nervosa is a life-threatening illness. Brain circuits believed to drive anorexia nervosa symptoms can be accessed with surgical techniques such as deep brain stimulation (DBS). Initial results suggest that DBS of the subcallosal cingulate is safe and associated with improvements in mood and anxiety.

fMRI of verbal and nonverbal memory processes in healthy and epileptogenic medial temporal lobes.

Material-specific memory impairments are a well-established consequence of unilateral medial temporal lobe damage. We used fMRI to investigate encoding and recognition of verbal and nonverbal stimuli using adaptations of tasks used successfully in clinical evaluations of patients with temporal lobe epilepsy (TLE). We studied two patient groups, one with left TLE and one with right TLE, and one group of healthy subjects.
