A Program to Improve the Quality of Life of Caregivers of Older Adults with Chronic Conditions: A Pilot Study
Background: Among the nearly 41.8 million family caregivers of older adults 50 years of age and older in the United States, only 30% of caregivers report receiving the education, resources, and support they need to feel competent in their role. Many existing programs focus on dementia-related caregiving, and programs are needed to address the caregiving needs of individuals with chronic conditions.
Method: A pilot study using a mixed methods design was conducted with eight participants. The pre and post. measure, Adult Carer Quality of Life (AC-QoL), and post program individual interviews were conducted.
Results: Six of the eight AC-QoL subscales showed improvement in quality of life and two showed decreases. The effect size was 0.63 for the total AC-QoL score, requiring 25–30 participants to achieve a power of 0.80 in a larger study. Interview data indicated the program provided an outside perspective of caregiver needs, provided information, resources and a support system, reduced their stress, and improved self-efficacy.
Conclusion: Further study of programs for caregivers of older adults with chronic conditions are important to fully address the needs of 35 million unpaid caregivers. Occupational therapists are ideally situated for leading the development of such programs given their unique practice focus and expertise
Those Who Need It Most: Maximizing Transit Accessibility and Removing Barriers to Employment in Areas of Concentrated Poverty
This research assesses the transportation assets and challenges faced by residents of Areas of Concentrated Poverty (ACPs), paying special attention to ACP50s—ACPs in which people of color comprise more than 50% of the population. The authors develop a graphically-facilitated survey blending multiple choice, free response, cognitive mapping and discussion questions to capture unmet transportation needs and user experience information difficult to gather in traditional travel behavior surveys. They find that participants’ activity spaces vary significantly based on car availability and local built form and that pedestrian environments around stops affect the experience of using transit in ACPs more strongly than transit service itself, leading to the conclusion that transit- and pedestrian-oriented community design is a significant equity issue
Consensus in Guidelines for Evaluation of DSD by the Texas Children's Hospital Multidisciplinary Gender Medicine Team
The Gender Medicine Team (GMT), comprised of members with expertise in endocrinology, ethics, genetics, gynecology, pediatric surgery, psychology, and urology, at Texas Children's Hospital and Baylor College of Medicine formed a task force to formulate a consensus statement on practice guidelines for managing disorders of sexual differentiation (DSD) and for making sex assignments. The GMT task force reviewed published evidence and incorporated findings from clinical experience. Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) was used to assess the quality of evidence presented in the literature for establishing evidence-based guidelines. The task force presents a consensus statement regarding specific diagnostic and therapeutic issues in the management of individuals who present with DSD. The consensus statement includes recommendations for (1) laboratory workup, (2) acute management, (3) sex assignment in an ethical framework that includes education and involvement of the parents, and (4) surgical management
Informing the Design of Privacy-Empowering Tools for the Connected Home
Connected devices in the home represent a potentially grave new privacy
threat due to their unfettered access to the most personal spaces in people's
lives. Prior work has shown that despite concerns about such devices, people
often lack sufficient awareness, understanding, or means of taking effective
action. To explore the potential for new tools that support such needs directly
we developed Aretha, a privacy assistant technology probe that combines a
network disaggregator, personal tutor, and firewall, to empower end-users with
both the knowledge and mechanisms to control disclosures from their homes. We
deployed Aretha in three households over six weeks, with the aim of
understanding how this combination of capabilities might enable users to gain
awareness of data disclosures by their devices, form educated privacy
preferences, and to block unwanted data flows. The probe, with its novel
affordances-and its limitations-prompted users to co-adapt, finding new control
mechanisms and suggesting new approaches to address the challenge of regaining
privacy in the connected home.Comment: 10 pages, 2 figures. To appear in the Proceedings of the 2020 CHI

Comparative Genomics of Emerging Human Ehrlichiosis Agents
Anaplasma (formerly Ehrlichia) phagocytophilum, Ehrlichia chaffeensis, and Neorickettsia (formerly Ehrlichia) sennetsu are intracellular vector-borne pathogens that cause human ehrlichiosis, an emerging infectious disease. We present the complete genome sequences of these organisms along with comparisons to other organisms in the Rickettsiales order. Ehrlichia spp. and Anaplasma spp. display a unique large expansion of immunodominant outer membrane proteins facilitating antigenic variation. All Rickettsiales have a diminished ability to synthesize amino acids compared to their closest free-living relatives. Unlike members of the Rickettsiaceae family, these pathogenic Anaplasmataceae are capable of making all major vitamins, cofactors, and nucleotides, which could confer a beneficial role in the invertebrate vector or the vertebrate host. Further analysis identified proteins potentially involved in vacuole confinement of the Anaplasmataceae, a life cycle involving a hematophagous vector, vertebrate pathogenesis, human pathogenesis, and lack of transovarial transmission. These discoveries provide significant insights into the biology of these obligate intracellular pathogens
Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial
Background
Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy

Mechanisms of Loss of Functions of Human Angiogenin Variants Implicated in Amyotrophic Lateral Sclerosis
Background: Mutations in the coding region of angiogenin (ANG) gene have been found in patients suffering from Amyotrophic Lateral Sclerosis (ALS). Neurodegeneration results from the loss of angiogenic ability of ANG (protein coded by ANG). In this work, we performed extensive molecular dynamics (MD) simulations of wild-type ANG and disease associated ANG variants to elucidate the mechanism behind the loss of ribonucleolytic activity and nuclear translocation activity, functions needed for angiogenesis. Methodology/Principal Findings: MD simulations were carried out to study the structural and dynamic differences in the catalytic site and nuclear localization signal residues between WT-ANG (Wild-type ANG) and six mutants. Variants K17I, S28N, P112L and V113I have confirmed association with ALS, while T195C and A238G single nucleotide polymorphisms (SNPs) encoding L35P and K60E mutants respectively, have not been associated with ALS. Our results show that loss of ribonucleolytic activity in K17I is caused by conformational switching of the catalytic residue His114 by 99u. The loss of nuclear translocation activity of S28N and P112L is caused by changes in the folding of the residues 31 RRR 33 that result in the reduction in solvent accessible surface area (SASA). Consequently, we predict that V113I will exhibit loss of angiogenic properties by loss of nuclear translocation activity and L35P by loss of both ribonucleolytic activity and nuclear translocation activity. No functional loss was inferred for K60E. The MD simulation results were supported by hydrogen bond interactio
