Physical Activity Barriers and Assets in Rural Appalachian Kentucky: A Mixed-Methods Study.

Obesity is an increasing public health concern in the U.S. and a contributor to chronic illness, with trends revealing a rise in adult obesity and chronic disease rates among the most vulnerable and disadvantaged populations, including those in rural communities. A mixed-methods approach was used to examine perspectives on perceived physical activity barriers, resources, and level of community support. Researchers utilized the socioecological model to examine the multiple domains that support physical activity in rural Appalachia. The present study focuses on baseline data, including a cohort survey to assess physical activity, health status, and barriers to physical activity, and five focus groups with elected community leaders, community residents, members, and key stakeholders to assess perspectives on physical activity barriers and resources within the county. The cohort survey sample (N = 152) reported a median of 6 barriers (range 0-13) to participating in at least 30 min of physical activity daily. The qualitative analysis yielded three overarching themes related to physical activity participation: lack of motivation, physical environment, and cultural barriers. This mixed-methods study revealed the challenges and perceptions among rural residents across the socioecological model when assessing physical inactivity. Findings can be used to tailor future interventions focused on expanding social support, designing infrastructure, and creating policies that promote physical activity.

Exploring the self-compassion of health-care social workers: How do they fare?

Indubitably, the challenges facing health-care social workers are becoming increasingly complex. Whilst these problematic professional circumstances compound the need for self-compassion among health-care social workers, few studies, if any, have explicitly examined self-compassion among this practitioner group. This cross-sectional study explored self-compassion among a sample of practitioners (N = 138) in one southeastern state. Results indicate that health-care social workers in this sample engage in self-compassion only moderately. Further, occupational and demographic/life characteristics (e.g., age, years practicing social work, average hours worked per week, health status, and relationship status, among others) are able to predict self-compassion scores. After a terse review of relevant literature, this paper will explicate findings from this study, discuss relevant points derived from said findings, and identify salient implication for health-care social work praxis.

Self-care among healthcare social workers: An exploratory study.

Despite growing interest in self-care, few studies have explicitly examined the self-care practices of healthcare social workers. This exploratory study investigated self-care among practitioners (N = 138) in one southeastern state. Overall, data suggest that healthcare social workers only moderately engaged in self-care. Additionally, analyses revealed significant differences in self-care practices by financial stability, overall health, and licensure status, respectively. Interestingly, perceived health status and current financial situation were significant predictors for overall self-care practices. After a brief review of the literature, this narrative will explicate findings, elucidate discussion points, identify salient implications, and conclude with areas for future research.

Synaptophysin and synaptojanin-1 in Down syndrome are differentially affected by Alzheimer's disease.

Adults with Down syndrome (DS) develop Alzheimer's disease (AD) neuropathology by 40 years of age. Synaptophysin (SYN) consistently declines with age and is further reduced with sporadic AD. Thus, we hypothesized that SYN would be reduced in DS with AD. The gene for synaptojanin-1 (SYNJ1), involved in synaptic vesicle recycling, is on chromosome 21. We measured SYN and SYNJ1 in an autopsy series of 39 cases with DS and 28 without DS, along with 7 sporadic AD cases. SYN was significantly lower in DSAD compared with DS alone and similar to sporadic AD. Reduced SYN is associated with AD neuropathology and with Aß levels in DS, as is seen in sporadic AD. SYNJ1 was significantly higher in DS and correlated with several measures of Aß. SYNJ1 was higher in DSAD and significantly higher than SYNJ1 in sporadic AD. Although significantly higher in DS, SYNJ1 is further increased with AD neuropathology suggesting interesting differences in a synapse-associated protein that is overexpressed in trisomy 21.

Brain responses to repeated visual experience among low and high sensation seekers: role of boredom susceptibility.

To better understand individual differences in sensation seeking and its components, including boredom susceptibility and experience seeking, we examined brain responses of high and low sensation seekers during repeated visual experience. Individuals scoring in the top and bottom quartiles from a college-aged population on the Brief Sensation-Seeking Scale (BSSS) participated in an event-related potentials (ERPs) experiment. Line drawings of common objects were randomly intermixed and presented 1-3 times. Sixty-four channel ERP responses were recorded while participants classified items as "man-made" or "not man-made" in a repetition priming task. The two groups showed different ERP responses at frontal electrode sites after seeing a visual stimulus for 400-800 ms. The frontal late positive components (LPC) showed different habituation of ERP responses to new and studied repeated objects between high and low sensation seekers. Source localization analysis (LORETA) indicated that during visual stimulus adaptation the ventral pre-frontal cortex showed lack of frontal involvement among high sensation seekers. Furthermore, frontal LPC latencies during repeated visual exposure correlated with boredom susceptibility and experience seeking subscales. The distinct profiles of brain responses to repeated visual experience in high and low sensation seekers provide evidence that individual differences in neural adaptation can be linked to personality dimensions.

The visual and haptic perception of natural object shape.

In this study, we evaluated observers' ability to compare naturally shaped three-dimensional (3-D) objects, using their senses of vision and touch. In one experiment, the observers haptically manipulated 1 object and then indicated which of 12 visible objects possessed the same shape. In the second experiment, pairs of objects were presented, and the observers indicated whether their 3-D shape was the same or different. The 2 objects were presented either unimodally (vision-vision or haptic-haptic) or cross-modally (vision-haptic or haptic-vision). In both experiments, the observers were able to compare 3-D shape across modalities with reasonably high levels of accuracy. In Experiment 1, for example, the observers' matching performance rose to 72% correct (chance performance was 8.3%) after five experimental sessions. In Experiment 2, small (but significant) differences in performance were obtained between the unimodal vision-vision condition and the two cross-modal conditions. Taken together, the results suggest that vision and touch have functionally overlapping, but not necessarily equivalent, representations of 3-D shape.
