Perceptions and barriers to the annual influenza vaccine compared with the coronavirus disease 2019 vaccine in an urban underserved population.

Background: For a vaccine to be successful, communities must perceive it as important, safe, effective, and necessary. However, there are many barriers and hesitancies to vaccination. Underserved patient populations may face additional challenges related to access and cost.

Identifying Nutrition Risk in a Charitable Pharmacy Population.

While prior research has shown that food insecurity and malnutrition worsen health outcomes and increase health care costs, nutrition risk is rarely assessed in the community setting. Tools exist to screen for food insecurity and malnutrition individually, but none screen for both. This study aimed to implement a dual-purpose screening tool to identify nutrition risk in a community setting, to characterize nutrition risk in a charitable pharmacy population, and to identify patients who screen positive for nutrition risk and connect them to community nutrition resources.

Regulation of Small GTPase Prenylation in the Nervous System.

Mevalonate pathway inhibitors have been extensively studied for their roles in cholesterol depletion and for inhibiting the prenylation and activation of various proteins. Inhibition of protein prenylation has potential therapeutic uses against neurological disorders, like neural cancers, neurodegeneration, and neurotramatic lesions. Protection against neurodegeneration and promotion of neuronal regeneration is regulated in large part by Ras superfamily small guanosine triphosphatases (GTPases), particularly the Ras, Rho, and Rab subfamilies.

Health care insecurity in the underserved: Effect of a charitable pharmacy model.

Objectives: The objectives of this study were to assess how a charitable pharmacy model affects patient perception of health care insecurity, physical and emotional functioning, and medication access in an underserved population.

Methods: New patients presenting for medication at their initial pharmacy visit at Charitable Pharmacy of Central Ohio were screened for eligibility during a 12-week enrollment period. Participants completed a baseline survey containing the Health Care Insecurity Measure (HCIM), Veterans RAND 12-Item Health Survey (VR-12), and medication access questions.

Prophylactic Riluzole Attenuates Oxidative Stress Damage in Spinal Cord Distraction.

Spinal cord injury (SCI) without radiographical abnormalities (SCIWORA) presents a significant challenge because of the loss of function despite an apparent normal anatomy. The cause of dysfunction is not understood, and specific treatment options are lacking. Some scoliosis corrective surgeries result in SCIWORA, where stretching of the spinal cord can lead to vascular compromise and hypoxia.

Assessment of self-care and medication adherence in individuals with mental health conditions.

Objectives: This descriptive study explored whether patients with mental health conditions engage in personal medicine (self-care activities) as part of their treatment regimen. Personal medicine is patient-identified and -initiated activities of self-care that can improve mental health through various means, including physical activity, social engagement, and spiritual connectedness. The purpose of this study was to explore patient engagement in personal medicine within an underserved population and to evaluate the impact self-care might have on self-reported medication use and adherence and patient perception of mental health control.

Atraumatic Spine Distraction Induces Metabolic Distress in Spinal Motor Neurons.

Corrective forces during spine deformity surgery, including distraction, impart significant stresses to the spinal cord that may result in permanent injury. Intraoperative neuromonitoring is commonly used by surgeons to recognize possible damage to the spinal cord in cases of evident traumatic or vascular damage to the spinal cord. However, mild insult to the spinal cord that does not result in obvious trauma or electrophysiological changes present a major clinical challenge as the mechanisms of this type of spinal cord injury (SCI) remain largely unknown, and thus preventive strategies are lacking.

Electromagnetic interference in intraoperative monitoring of motor evoked potentials and a wireless solution.

Intraoperative neurophysiological monitoring (IONM) is utilized to minimize neurological morbidity during spine surgery. Transcranial motor evoked potentials (TcMEPs) are principal IONM signals in which the motor cortex of the subject is stimulated with electrical pulses and the evoked potentials are recorded from the muscles of interest. Currently available monitoring systems require the connection of 40-60 lengthy lead wires to the patient.

Charitable pharmacy services: Impact on patient-reported hospital use, medication access, and health status.

Objective: To evaluate the impact that Charitable Pharmacy of Central Ohio (CPCO), a pharmacy providing free pharmacy services and medications, had on an indigent patient population by determining the change in patient-reported hospital use, ability to access medications, and perception of health status after receiving CPCO services.

Design: Cross-sectional study with face-to-face interviews using a convenience sample.

Setting: Columbus, OH, in January to March 2013.

Normal molecular repair mechanisms in regenerative peripheral nerve interfaces allow recording of early spike activity despite immature myelination.

Clinical use of neurally controlled prosthetics has advanced in recent years, but limitations still remain, including lacking fine motor control and sensory feedback. Indwelling multi-electrode arrays, cuff electrodes, and regenerative sieve electrodes have been reported to serve as peripheral neural interfaces, though long-term stability of the nerve-electrode interface has remained a formidable challenge. We recently developed a regenerative multi-electrode interface (REMI) that is able to record neural activity as early as seven days post-implantation.

A wireless system for monitoring transcranial motor evoked potentials.

Intraoperative neurophysiological monitoring (IONM) is commonly used as an attempt to minimize neurological morbidity from operative manipulations. The goal of IONM is to identify changes in the central and peripheral nervous system function prior to irreversible damage. Intraoperative monitoring also has been effective in localizing anatomical structures, including peripheral nerves and sensorimotor cortex, which helps guide the surgeon during dissection.

Differential activation of Rac1 and RhoA in neuroblastoma cell fractions.

The Rho guanine nucleotide triphosphatases (GTPases) Rac1 and RhoA are important regulators of axon growth. However, the specific roles each plays are complicated by implications that each is involved in promoting and inhibiting neurite outgrowth. Differential regulation of Rac1 and RhoA activation in cell bodies and growth cones may be important in directing axon growth.

Hopping in the electron-transfer photocycle of the 1:1 complex of Zn-cytochrome c peroxidase with cytochrome c.

The physiological electron-transfer (ET) partners, cytochrome c peroxidase (CcP) and cytochrome c (Cc)1, can be modified to exhibit photoinitiated ET through substitution of Zn (or Mg) for Fe in either partner. Laser excitation of the Zn-porphyrin (ZnP) to its triplet excited state (3ZnP) initiates direct heme-heme ET to the ferriheme center of its partner across the protein-protein interface. This photoinitiated ET produces the charge-separated intermediate, I = [ZnP+CcP, Fe2+Cc], with a metalloporphyrin pi-cation radical (ZnP+) in the donor protein and a ferroheme acceptor protein.

Differential influence of dynamic processes on forward and reverse electron transfer across a protein-protein interface.

We propose that the forward and reverse halves of a flash-induced protein-protein electron transfer (ET) photocycle should exhibit differential responses to dynamic interconversion of configurations when the most stable configuration is not the most reactive, because the reactants exist in different initial configurations: the flash-photoinitiated forward ET process begins with the protein partners in an equilibrium ensemble of configurations, many of which have little or no reactivity, whereas the reactant of the thermal back ET (the charge-separated intermediate) is formed in a nonequilibrium, "activated" protein configuration. We report evidence for this proposal in measurements on (i) mixed-metal hemoglobin hybrids, (ii) the complex between cytochrome c peroxidase and cytochrome c, and (iii and iv) the complexes of myoglobin and isolated hemoglobin alpha-chains with cytochrome b(5). For all three systems, forward and reverse ET does respond differently to modulation of dynamic processes; further, the response to changes in viscosity is different for each system.

Interprotein electron transfer in a confined space: uncoupling protein dynamics from electron transfer by sol-gel encapsulation.

In this paper, we describe the first observations of photoinitiated interprotein electron transfer (ET) within sol-gels. We have encapsulated three protein-protein complexes, specifically selected because they represent a full range of affinities, are sensitive to different types of dynamic processes, and thus are expected to respond differently to sol-gel encapsulation. The three systems are (i) the [Zn, Fe(3+)L] mixed-metal hemoglobin hybrids, where the alpha(1)-Zn and beta(2)-Fe subunits correspond to a "predocked" protein-protein complex with a crystallographically defined interface (Natan, M.
