Highlights This survey collected information about depression, anxiety, and physical activity levels of 1,046 older adults living in North America under current social distancing guidelines during the COVID-19 pandemic. The primary question addressed by the study was whether total physical activity levels and physical activity intensities performed by older adults during COVID-19-related SDG was related to mental health symptoms. The results of this study showed that greater total physical activity levels were associated with lower scores on the Geriatric Depression Scale. Additionally, a hierarchical regression analysis suggests that light and vigorous-intensity physical activity were significant, independent contributors towards depression symptoms in this population. These findings suggest that higher levels of physical activity levels may help alleviate some of the negative mental health symptoms experienced by older adults, while social distancing guidelines are followed during the COVID-19 pandemic.

Background: Exercise training (ET) has neuroprotective effects in the hippocampus, a key brain region for memory that is vulnerable to age-related dysfunction. Objective: We investigated the effects of ET on functional connectivity (FC) of the hippocampus in older adults with mild cognitive impairment (MCI) and a cognitively normal (CN) control group. We also assessed whether the ET-induced changes in hippocampal FC (Δhippocampal-FC) are associated with changes in memory task performance (Δmemory performance). Methods: 32 older adults (77.0±7.6 years; 16 MCI and 16 CN) participated in the present study. Cardiorespiratory fitness tests, memory tasks (Rey Auditory Verbal Learning Test (RAVLT) and Logical Memory Test (LM)), and resting-state fMRI were administered before and after a 12-week walking ET intervention. We utilized a seed-based correlation analysis using the bilateral anterior and posterior hippocampi as priori seed regions of interest. The associations of residualized ET-induced Δhippocampal-FC and Δmemory performance were assessed using linear regression. Results: There were significant improvements in RAVLT Trial 1 and LM test performance after ET across participants. At baseline, MCI, compared to CN, demonstrated significantly lower posterior hippocampal FC. ET was associated with increased hippocampal FC across groups. Greater ET-related anterior and posterior hippocampal FC with right posterior cingulate were associated with improved LM recognition performance in MCI participants. Conclusion: Our findings indicate that hippocampal FC is significantly increased following 12-weeks of ET in older adults and, moreover, suggest that increased hippocampal FC may reflect neural network plasticity associated with ET-related improvements in memory performance in individuals diagnosed with MCI.

Individuals with Mild Cognitive Impairment (MCI) are at an elevated risk of dementia and exhibit deficits in cognition and cortical gray matter (GM) volume, thickness, and microstructure. Meanwhile, exercise training appears to preserve brain function and macrostructure may help delay or prevent the onset of dementia in individuals with MCI. Yet, our understanding of the neurophysiological effects of exercise training in individuals with MCI remains limited. Recent work suggests that the measures of gray matter microstructure using diffusion imaging may be sensitive to early cognitive and neurophysiological changes in the aging brain. Therefore, this study is aimed to determine the effects of exercise training in cognition and cortical gray matter microstructure in individuals with MCI vs. cognitively healthy older adults. Fifteen MCI participants and 17 cognitively intact controls (HC) volunteered for a 12-week supervised walking intervention. Following the intervention, MCI and HC saw improvements in cardiorespiratory fitness, performance on Trial 1 of the Rey Auditory Verbal Learning Test (RAVLT), a measure of verbal memory, and the Controlled Oral Word Association Test (COWAT), a measure of verbal fluency. After controlling for age, a voxel-wise analysis of cortical gray matter diffusivity showed individuals with MCI exhibited greater increases in mean diffusivity (MD) in the left insular cortex than HC. This increase in MD was positively associated with improvements in COWAT performance. Additionally, after controlling for age, the voxel-wise analysis indicated a main effect of Time with both groups experiencing an increase in left insular and left and right cerebellar MD. Increases in left insular diffusivity were similarly found to be positively associated with improvements in COWAT performance in both groups, while increases in cerebellar MD were related to gains in episodic memory performance. These findings suggest that exercise training may be related to improvements in neural circuits that govern verbal fluency performance in older adults through the microstructural remodeling of cortical gray matter. Furthermore, changes in left insular cortex microstructure may be particularly relevant to improvements in verbal fluency among individuals diagnosed with MCI.

Information on the long-term effects of early trauma and how such effects are manifested in treatment was obtained through interviews with thirty analysts who had treated an adult patient with a circumscribed trauma in the first four years of life. Childhood traumas fell into four categories: medical/accidental; separation/loss; witnessing a traumatic event; and physical/sexual abuse. Traumatic carryover was recorded in terms of explicit memories, implicit memories (somatic reliving, traumatic dreams, affective memories, behavioral reenactments, and transference phenomena), and global carryover effects (generalized traumatic affective states, defensive styles, patterns of object relating, and developmental disruptions). Linkages between the early trauma and adult symptomatology could be posited in almost every case, yet the clinical data supporting such linkages was often fragmented and ambiguous. Elements of patients' traumas appeared to be dispersed along variable avenues of expression and did not appear amenable to holistic, regressive reworking in treatment. The data did not support linear models of traumatic carryover or the idea that early traumatic experiences will be directly accessible in the course of an analysis. Factors that we believe help explain why traumatic aftereffects in our sample were so heterogeneous and difficult to track over the long term are discussed.

The purpose of this report is to describe and discuss the development and implementation of an interprofessional educational (IPE) program for students on a regional medical campus. IPE is important in training the next generation of health care professionals. Regional medical campuses often have reduced IPE activities due to limited resources and their distance from their main campuses. However, regional campuses can also provide opportunities for innovative solutions to provide IPE learning experiences. This article demonstrated how one regional campus created innovative opportunities to meet student needs.
