Aim: The purpose of this study was to evaluate faculty and student perceptions of a fall risk assessment and prevention activity for older adults offered in multiple community settings by health professional faculty and students. Background: In the US, the percentage of adults 65 and older who fell was more than 29% in 2018. Among states, Arkansas ranks 48th with 35.2% of older adults reporting a fall (CDC Behavioral Risk Factor Surveillance System, 2018). Methods: Four senior centers in Northwest Arkansas hosted a [...]

This paper describes the synthesis of Pd0.70-Nix-By nanoparticles (x:y = 0.30:0, 0:0.30, 0.25:0.05, 0.20:0.10, 0.15:0.15, and 0.10:0.20) supported on carbon Vulcan XC-72 R by the chemical reduction method using ethylene glycol as a reducing agent for the study of the electrochemical oxidation of ethanol in alkaline media. Neither surfactants nor templates were used during the syntheses. The catalysts were physically characterized by transmission electron microscopy that showed the formation of nanoparticles with di [...]

Background: Vestibular schwannoma is an intracranial tumor which can lead to devastating neurological deficit and is prone to recurrence after surgery. Patients with inherited neurofibromatosis type 2 (NF2) syndrome are particularly susceptible to bilateral and aggressive schwannomas. However, the genome of vestibular schwannomas is not well known. There is an imminent need of developing effective chemotherapeutic agents either as a primary treatment modality or as adjuvant therapy for these patients. Methods: Here [...]

The prevalence of diabetes in older people is increasing. Diabetes in old age is associated with increased risk of mental dysfunction. Cognitive dysfunction and mood disorders such as depression, anxiety and diabetes-related distress tend to coexist in older people with diabetes and appear to have bidirectional relationship acting as a risk factor and, at the same time, as a consequence of diabetes. To break the vicious circle of this complex reciprocal relationship between diabetes and mental dysfunction, early id [...]

Objective: To report a unique case of cerebellopontine angle glioblastoma with concurrent spinal cord involvement. Background: Glioblastoma (GBM) is the most common primary malignancy of the central nervous system (CNS), comprising 46.6% of all CNS malignancies. By anatomic location, cerebellopontine angle (CPA) GBMs are exceedingly rare. To our knowledge, the following case represents the tenth reported case of CPA GBM and the first with a corresponding spinal cord tumor on presentation. Methods: Retrospective cha [...]

Mind-body interventions have shown promise for improving prenatal mental health. The purpose of this study was to investigate the feasibility of a prenatal mind-body intervention delivered remotely due to COVID-19 and preliminary efficacy with respect to mental health outcomes. This study used a simultaneous mixed methods approach (n = 27). Mixed methods data were collected to evaluate the feasibility and preliminary efficacy of the remotely delivered program (I.e., acceptability, practicality, demand, sustainabili [...]

Background: Most individuals with disabilities in the US live in family settings; in some families, siblings are default long-term support providers. Although researchers have explored the roles of parent caregivers, the roles of sibling caregivers need attention. Methods: In this study, we examined caregiving processes and outcomes among 322 adult sibling support providers (SSPs) with a range of support roles. Adapting a model of caregiving outcomes, we used structural equation modeling to assess relationships amo [...]

The approach to diagnosing fungal infections following solid organ transplantation (SOT) is patient-specific. An assessment of an individual’s risk for particular infections, also understood as the pre-test probability, should guide appropriate diagnostic testing whereas diagnostic stewardship is needed to produce interpretable, actionable and cost-sensitive results. This review provides a cognitive framework for practitioners aiming to diagnose fungal infections in recipients of SOT, taking into consideration the [...]

This article aims to describe the relationship between donors and their recipients in the context of organ transplants. This analysis is made in the light of Marcel Mauss’s work, offering an expansion on an analysis of his discussion on the “spirit of the gift” and his idea that gifts require reciprocation. It is argued that some recipients of donated organs receive a personal element from the donor in that there is a transfer or sharing of the donors’ personality and spiritual qualities. The article examines the n [...]

Fe-rich alloys have been widely studied as catalyst materials for the cathodic oxygen reduction reaction (ORR) in hydrogen fuel cells, and many have shown high activities. The stability of Fe-rich catalysts has also been researched, and some studies have shown promising results using an accelerated stress test (AST), which uses a potential cycling method. However, for commercial fuel cell applications, such as standby power systems, the catalyst has to tolerate a high potential for a long period, which can not be r [...]
