Proximity to Hospital-Based Obstetric Care in a Maternity Desert in the Deep South.

Objectives. To examine the accessibility of hospital facilities with maternity care services in 1 rural county in Alabama in preparation for the initiation of prenatal care services at a federally qualified health center. Methods. We analyzed driving distance (in miles) from maternal city of residence in Conecuh County, Alabama to hospital of delivery, using 2019-2021 vital statistics data and geographic information system (GIS) software. Results. A total of 370 births to mothers who have home addresses in Conecuh County were reported, and 368 of those were in hospital facilities. The majority of deliveries were less than 30 miles (median = 23 miles) from the maternal city of residence. Some women traveled more than 70 miles for obstetrical care. Conclusions. Pregnant patients in Conecuh County experience significant geographic barriers related to perinatal care access. Using GIS for this analysis is a promising approach to better understand the unique challenges of pregnant individuals in this rural population. Public health policy efforts need to be geographically tailored to address these disparities. (Am J Public Health. 2024;114(S4):S330-S333. https://doi.org/10.2105/AJPH.2024.307692).

Hydrogel-Based Pre-Clinical Evaluation of Repurposed FDA-Approved Drugs for AML.

In vivo models of acute myeloid leukemia (AML) are low throughput, and standard liquid culture models fail to recapitulate the mechanical and biochemical properties of the extracellular matrix-rich protective bone marrow niche that contributes to drug resistance. Candidate drug discovery in AML requires advanced synthetic platforms to improve our understanding of the impact of mechanical cues on drug sensitivity in AML. By use of a synthetic, self-assembling peptide hydrogel (SAPH) of modifiable stiffness and composition, a 3D model of the bone marrow niche to screen repurposed FDA-approved drugs has been developed and utilized. AML cell proliferation was dependent on SAPH stiffness, which was optimized to facilitate colony growth. Three candidate FDA-approved drugs were initially screened against the THP-1 cell line and mAF9 primary cells in liquid culture, and EC50 values were used to inform drug sensitivity assays in the peptide hydrogel models. Salinomycin demonstrated efficacy in both an 'early-stage' model in which treatment was added shortly after initiation of AML cell encapsulation, and an 'established' model in which time-encapsulated cells had started to form colonies. Sensitivity to Vidofludimus treatment was not observed in the hydrogel models, and Atorvastatin demonstrated increased sensitivity in the 'established' compared to the 'early-stage' model. AML patient samples were equally sensitive to Salinomycin in the 3D hydrogels and partially sensitive to Atorvastatin. Together, this confirms that AML cell sensitivity is drug- and context-specific and that advanced synthetic platforms for higher throughput are valuable tools for pre-clinical evaluation of candidate anti-AML drugs.

Factors associated with HPV vaccination initiation among United States college students.

Human papillomavirus (HPV) remains the most common sexually transmitted infection (STI) in the U.S. despite widespread availability of a safe, effective vaccine. Although young adults are at greatest risk of HPV infection, extensive vaccine promotion and intervention efforts has been directed toward 11-12-year-olds. College students represent an ideal audience for HPV vaccine "catch-up;" however, research indicates inconsistent HPV vaccination rates within this demographic. An online survey assessing HPV and HPV vaccine knowledge and behaviors was distributed to all undergraduate college students at a large, public university in the Deep South region of the U.S. The primary outcome was receipt of HPV vaccination (binary response options of Yes/No). Logistic regression analyses were performed to determine predictors of HPV vaccination. Of the 1,725 who completed the survey, 47.0% reported having received at least one dose of HPV vaccine; overall series completion (series = 3 doses for this population) was 17.4%. The primary outcome was HPV initiation among college students, defined as having received at least one dose of the HPV vaccine. Results indicated substantial gaps in participants' knowledge of their vaccination status. Provider and parental recommendations as well as social influences were shown to significantly impact student vaccination status, emphasizing the importance of incorporating these elements in future interventions, potentially as multi-level strategies. Future college interventions should address HPV and vaccination knowledge and the importance of provider and parental recommendations.

The importance of cell culture parameter standardization: an assessment of the robustness of the 2102Ep reference cell line.

Work undertaken using the embryonic carcinoma 2102Ep line, highlighted the requirement for robust, well-characterized and standardized protocols. A systematic approach utilizing 'quick hit' experiments demonstrated variability introduced into culture systems resulting from slight changes to culture conditions (route A). This formed the basis for longitudinal experiments investigating long-term effects of culture parameters including seeding density and feeding regime (route B).Results demonstrated that specific growth rates (SGR) of passage 59 (P59) cells seeded at 20,000 cells/cm2 and subjected to medium exchange after 48h prior to reseeding at 72h (route B2) on average was marginally higher than, P55 cells cultured under equivalent conditions (route A1); whereby SGR values were (0.021±0.004) and (0.019±0.004). Viability was higher in route B2 over 10 passages with average viability reported as (86.3%±8.1) compared to route A1 (83.3±8.8). The metabolite data demonstrated both culture route B1 (P57 cells seeded at 66,667 cells/cm2) and B2 had consistent-specific metabolite rates (SMR) for glucose, but SMR values of route B1 was consistently lower than route B2 (0.00001 mmol, cell-1.d-1 and 0.000025).Results revealed interactions between phenotype, SMR and feeding regime that may not be accurately reflected by growth rate or observed morphology. This implies that current schemes of protocol control do not adequately account for variability, since key cell characteristics, including phenotype and SMR, change regardless of standardized seeding densities. This highlights the need to control culture parameters through defined protocols, for processes that involve culture for therapeutic use, biologics production, and reference lines.

Rebooting a sports pharmacy advanced pharmacy practice experience: Utilizing medicinal chemistry as a foundational approach to get pharmacists back in the game.

BACKGROUND AND PURPOSE: To implement a sports pharmacy advanced pharmacy practice experience (SP-APPE) utilizing medicinal chemistry as a foundational approach. EDUCATIONAL ACTIVITY AND SETTING: A student-pharmacist and medicinal chemistry faculty member collaborated to reboot a SP-APPE. Approached from a medicinal chemistry perspective and tailored to the infrastructure of the university, three fourth-year student-pharmacists piloted the SP-APPE (fall 2017 to fall 2018). Various performance enhancing drugs (PEDs) and supplements were investigated. Student-pharmacists evaluated general knowledge of PEDs along with the perceived value of pharmacists in sports among student-athletes, athletic personnel, and pre-APPE students. FINDINGS: By demonstrating how legitimate medications were chemically similar to substances banned by sports governing agencies, comparing chemical structures/pharmacophores of PEDs to those of various prescription drugs, and comprehending athletes' misuse of PEDs, student-pharmacists educated student-athletes and athletic personnel on pertinent topics spanning pharmacy and sports (e.g., marijuana, medication sharing, deciphering supplement labels). Laboratory analytical methods that detect PEDs and educational points regarding potential adverse health risks posed by PED usage were also reviewed. Survey participants (approximately 75%, n = 134) perceived pharmacists as valuable to student-athletes and athletic personnel. Student-pharmacists indicated that medicinal chemistry knowledge was strengthened by completing the APPE and relevant to their pharmacy careers. SUMMARY: Based on medicinal chemistry principles, the SP-APPE provided a venue for student-pharmacists to interact with athletics, assist with drug information education, and identify drugs or supplements as chemically related to those banned by sports governing agencies. Confident in medicinal chemistry concepts, student-pharmacists translated their expertise to benefit the patient/student-athlete.
