Knee Range Of Motion: Reliability And Agreement Of 3 Measurement Methods, 2019 Wright State University - Main Campus
Knee Range Of Motion: Reliability And Agreement Of 3 Measurement Methods, Paul G. Peters, Michael A. Herbenick, Philip A. Anloague, Ronald J. Markert, L. Joseph Rubino
We conducted a study to compare 3 methods of measuring knee range of motion: visual estimation by physicians, hand goniometry by physical therapists, and radiographic goniometry. We hypothesized that reliability would be high within and across all techniques. We found intrarater and interrater reliability to be satisfactory for visual estimation, hand goniometry, and radiographic goniometry. Interrater reliability across methods did not agree satisfactorily. Between-methods differences in estimating knee range of motion may result from variations in technique among physicians and physical therapists.

Exosomes can serve as delivery vehicles for advanced therapeutics. The components necessary and sufficient to support exosomal delivery have not been established. Here we connect biochemical composition and activity of exosomes to optimize exosome-mediated delivery of small interfering RNAs (siRNAs). This information is used to create effective artificial exosomes. We show that serum-deprived mesenchymal stem cells produce exosomes up to 22-fold more effective at delivering siRNAs to neurons than exosomes derived from control cells. Proteinase treatment of exosomes stops siRNA transfer, indicating that surface proteins on exosomes are involved in trafficking. Proteomic and lipidomic analyses show that exosomes derived in ...

Knop, Gensheng Wang, Janet Benson, Kristen E. Coleman, Allison M. Keeler, Christian Mueller, Louis G. Chicoine, Jeffrey D. Chulay, Terence R. Flotte
Phase 1 and phase 2 gene therapy trials using intramuscular (IM) administration of a recombinant adeno-associated virus serotype 1 (rAAV1) for replacement of serum alpha-1 antitrypsin (AAT) deficiency have shown long-term (5-year) stable transgene expression at approximately 2% to 3% of therapeutic levels, arguing for the long-term viability of this approach to gene replacement of secreted serum protein deficiencies. However, achieving these levels required 100 IM injections to deliver 135 mL of vector, and further dose escalation is limited by the scalability of direct IM injection. To further advance the dose escalation, we sought to bridge the rAAV-AAT clinical development ...

A Highly Expressed Intestinal Cysteine Protease Of Ancylostoma Ceylanicum Protects Vaccinated Hamsters From Hookworm Infection, Jason B. Noon, Erich M. Schwarz, Gary R. Ostroff, Raffi V. Aroian
Open Access Articles
BACKGROUND: Human hookworms (Necator americanus, Ancylostoma duodenale, and Ancylostoma ceylanicum) are intestinal blood-feeding parasites that infect ~500 million people worldwide and are among the leading causes of iron-deficiency anemia in the developing world. Drugs are useful against hookworm infections, but hookworms rapidly reinfect people, and the parasites can develop drug resistance. Therefore, having a hookworm vaccine would be of tremendous benefit.
METHODOLOGY/PRINCIPAL FINDINGS: We investigated the vaccine efficacy in outbred Syrian hamsters of three A. ceylanicum hookworm antigen candidates from two classes of proteins previously identified as promising vaccine candidates. These include two intestinally-enriched, putatively secreted cathepsin B cysteine ...

Senior Honors Projects
Urolithiasis, or the formation of stones in the urinary tract, is a potentially painful process that impacts many people across the world. However, the results of clinical trials disagree on the proper treatment and management of kidney stones. One way to help those who have kidney stones is to perform extracorporeal shock wave lithotripsy (SWL), a medical procedure in which shock waves are directed towards kidney stones to prevent them from migrating and causing pain. Following SWL, patients are sometimes given additional medications, such as alpha blockers (e.g., tamsulosin), to aid in the passage of the stones. However, the ...

Current prescribing practices for major depressive disorder (MDD) produce limited treatment success. Although pharmacogenomics may improve outcomes by identifying genetically inappropriate medications, studies to date were limited in scope. Outpatients (N=1167) diagnosed with MDD and with a patient- or clinician-reported inadequate response to at least one antidepressant were enrolled in the Genomics Used to Improve DEpression Decisions (GUIDED) trial - a rater- and patient-blind randomized controlled trial. Patients were randomized to treatment as usual (TAU) or a pharmacogenomics-guided intervention arm in which clinicians had access to a pharmacogenomic test report to inform medication selections (guided-care). Medications were considered congruent ('use ...

Community Engagement and Research Symposia
AIM: A poorly understood challenge is why many women with opioid use disorder do not remain engaged with medications for opioid use disorder (MOUD; e.g., methadone, buprenorphine, naltrexone) long enough to achieve sustained benefits. We aimed to identify barriers and facilitators that impact women's MOUD adherence.
METHODS: We conducted in-person interviews and focus groups with 20 women who had received MOUD for at least 90 days in Springfield and Holyoke, Massachusetts in 2018. Using grounded theory, we inductively identified major themes and selected illustrative quotations.
FINDINGS: Gender-specific barriers to treatment are shaped by MOUD-related stigma stemming from multiple ...
