Diabetic retinopathy screenings in West Virginia: an assessment of teleophthalmology implementation.

BACKGROUND: The prevalence of diabetes in the state of West Virginia (WV) is amongst the highest in the United States, making diabetic retinopathy (DR) and diabetic macular edema (DME) a major epidemiological concern within the state. Several challenges exist regarding access to eye care specialists for DR screening in this rural population. A statewide teleophthalmology program has been implemented. We analyzed real-world data acquired via these systems to explore the concordance between image findings and subsequent comprehensive eye exams and explore the impact of age on image gradeability and patient distance from the West Virginia University (WVU) Eye Institute on follow-up. METHODS: Nonmydriatic fundus images of diabetic eyes acquired at primary care clinics throughout WV were reviewed by retina specialists at the WVU Eye Institute. Analysis included the concordance between image interpretations and dilated examination findings, hemoglobin A1c (HbA1c) levels and DR presence, image gradeability and patient age, and distance from the WVU Eye Institute and follow-up compliance. RESULTS: From the 5,512 fundus images attempted, we found that 4,267 (77.41%) were deemed gradable.  Out of the 289 patients whose image results suggested DR, 152 patients (52.6%) followed up with comprehensive eye exams-finding 101 of these patients to truly have DR/DME and allowing us to determine a positive predictive value of 66.4%. Patients within the HbA1c range of 9.1-14.0% demonstrated significantly greater prevalence of DR/DME (p < 0.01).  We also found a statistically significant decrease in image gradeability with increased age.  When considering distance from the WVU Eye Institute, it was found that patients who resided within 25 miles demonstrated significantly greater compliance to follow-up (60% versus 43%, p < 0.01). CONCLUSIONS: The statewide implementation of a telemedicine program intended to tackle the growing burden of DR in WV appears to successfully bring concerning patient cases to the forefront of provider attention.  Teleophthalmology addresses the unique rural challenges of WV, but there is suboptimal compliance to essential follow-up with comprehensive eye exams. Obstacles remain to be addressed if these systems are to effectively improve outcomes in DR/DME patients and diabetic patients at risk of developing these sight-threatening pathologies.

Organizational commitment to diversity, equity, and inclusion: A strategic path forward.

PURPOSE: To describe an approach to diversity, equity, and inclusion (DEI) strategy development at a school of pharmacy aimed at stakeholder investment and infrastructure that can address systemic challenges in various healthcare settings. SUMMARY: The UNC Eshelman School of Pharmacy utilized an organizational approach focused on infrastructure to produce a diverse and inclusive school community. The Office of Organizational Diversity and Inclusion (ODI) established vision and mission statements to represent the school's commitment and conducted a comprehensive environmental scan to compose a shared vision. Students, faculty, staff, and alumni participated in a series of retreats, symposiums, and focus groups to identify opportunities to cultivate a diverse and inclusive school community. A working group comprised of key leaders in the school developed and launched a 3-year DEI Strategic Plan along with initiatives and metrics for year 1. The plan's 3 priorities were (1) to recruit and retain diverse talent, (2) to prepare culturally intelligent professionals, and (3) to build an inclusive community. The ODI collaborated with internal and external stakeholders, which included students, faculty, staff, postdocs, alumni, and partners from health systems, industry, and other institutions and organizations, to initiate, implement, and monitor progress through an organizational approach to establish accountability and greater commitment. CONCLUSION: An organizational approach to DEI strategy through stakeholder engagement and infrastructure increased commitment and shared ownership among members of the school community. Applications in an organizational approach can be adapted to multiple healthcare settings to contribute to the cultural transformation necessary to develop a diverse and inclusive healthcare workforce.

Supercritical fluid extraction (SCFE) as green extraction technology for high-value metabolites of algae, its potential trends in food and human health.

Application of high-value algal metabolites (HVAMs) in cosmetics, additives, pigments, foods and medicines are very important. These HVAMs can be obtained from the cultivation of micro- and macro-algae. These metabolites can benefit human and animal health in a physiological and nutritional manner. However, because of conventional extraction methods and their energy and the use of pollutant solvents, the availability of HVAMs from algae remains insufficient. Receiving their sustainability and environmental benefits have recently made green extraction technologies for HVAM extractions more desirable. But very little information is available about the technology of green extraction of algae from these HVAM. This review, therefore, highlights the supercritical fluid extraction (SCFE) as principal green extraction technologyand theirideal parameters for extracting HVAMs. In first, general information is provided concerning the HVAMs and their components of macro and micro origin. The review also includes a description of SCFE technology's properties, instrumentation operation, solvents used, and the merits and demerits. Moreover, there are several HVAMs associated with their numerous high-level biological activities which include high-level antioxidant, anti-inflammatory, anticancer and antimicrobial activity and have potential health-beneficial effects in humans since they are all HVAMs, such as foods and nutraceuticals. Finally, it provides future insights, obstacles, and suggestions for selecting the right technologies for extraction.

Economic evaluation of whole genome sequencing for pathogen identification and surveillance - results of case studies in Europe and the Americas 2016 to 2019.

BackgroundWhole genome sequencing (WGS) is increasingly used for pathogen identification and surveillance.AimWe evaluated costs and benefits of routine WGS through case studies at eight reference laboratories in Europe and the Americas which conduct pathogen surveillance for avian influenza (two laboratories), human influenza (one laboratory) and food-borne pathogens (five laboratories).MethodsThe evaluation focused on the institutional perspective, i.e. the 'investment case' for implementing WGS compared with conventional methods, based on costs and benefits during a defined reference period, mostly covering at least part of 2017. A break-even analysis estimated the number of cases of illness (for the example of Salmonella surveillance) that would need to be avoided through WGS in order to 'break even' on costs.ResultsOn a per-sample basis, WGS was between 1.2 and 4.3 times more expensive than routine conventional methods. However, WGS brought major benefits for pathogen identification and surveillance, substantially changing laboratory workflows, analytical processes and outbreaks detection and control. Between 0.2% and 1.1% (on average 0.7%) of reported salmonellosis cases would need to be prevented to break even with respect to the additional costs of WGS.ConclusionsEven at cost levels documented here, WGS provides a level of additional information that more than balances the additional costs if used effectively. The substantial cost differences for WGS between reference laboratories were due to economies of scale, degree of automation, sequencing technology used and institutional discounts for equipment and consumables, as well as the extent to which sequencers are used at full capacity.

Anaphylaxis-a 2020 practice parameter update, systematic review, and Grading of Recommendations, Assessment, Development and Evaluation (GRADE) analysis.

Anaphylaxis is an acute, potential life-threatening systemic allergic reaction that may have a wide range of clinical manifestations. Severe anaphylaxis and/or the need for repeated doses of epinephrine to treat anaphylaxis are risk factors for biphasic anaphylaxis. Antihistamines and/or glucocorticoids are not reliable interventions to prevent biphasic anaphylaxis, although evidence supports a role for antihistamine and/or glucocorticoid premedication in specific chemotherapy protocols and rush aeroallergen immunotherapy. Evidence is lacking to support the role of antihistamines and/or glucocorticoid routine premedication in patients receiving low- or iso-osmolar contrast material to prevent recurrent radiocontrast media anaphylaxis. Epinephrine is the first-line pharmacotherapy for uniphasic and/or biphasic anaphylaxis. After diagnosis and treatment of anaphylaxis, all patients should be kept under observation until symptoms have fully resolved. All patients with anaphylaxis should receive education on anaphylaxis and risk of recurrence, trigger avoidance, self-injectable epinephrine education, referral to an allergist, and be educated about thresholds for further care.

Surgical treatment of young women with breast cancer: Public vs private hospitals.

Disparities in breast cancer treatment have been documented in young and underserved women. This study aimed to determine whether surgical disparities exist among young breast cancer patients by comparing cancer treatment at a public safety-net hospital (BH) and private cancer center (PCC) within a single institution. This was a retrospective study of young women (<45) diagnosed with invasive breast cancer (stage I-III) from 2011-2016. Patient information was abstracted from the breast cancer database at BH and PCC. Demographic variables, surgery type, method of presentation, and stage were analyzed using Pearson's chi-square tests and binary logistic regression. A total of 275 patients between ages 25-45 with invasive breast cancer (Stage I-III) were included in the study. There were 69 patients from BH and 206 patients from PCC. At PCC, the majority of patients were Caucasian (68%), followed by Asian (11%), Hispanic (10%), and African American (8.7%). At BH, patients were mostly Hispanic (47.8%), followed by Asian (27.5%), and African American (10.1%). At PCC, 82% had a college/graduate degree versus 18.6% of patients at BH (P < 0.001). All patients at PCC reported English as their primary language versus 30% of patients at BH (P < 0.001). Patients at PCC were more likely to present with lower stage cancer (P = 0.04), and less likely to present with a palpable mass (P = 0.04). Hospital type was not a predictor of receipt of mastectomy (P = 0.5), nor was race, primary language, or education level. Of patients who received a mastectomy, 87% at BH and 76% at PCC had immediate reconstruction. Surgical management of young women with breast cancer in a public hospital versus private hospital setting was equivalent, even after controlling for race, primary language, stage, and education level.

Implementation of comprehensive medication management at supermarket pharmacies in a pharmacy network.

OBJECTIVE: To garner experience with the early implementation of pharmacist-provided comprehensive medication management at a regional supermarket pharmacy during the initial launch of a statewide community pharmacy enhanced services network payer contract. METHODS: A series of key informant interviews were conducted with pharmacists at Giant Eagle Pharmacy locations in Pennsylvania. To be eligible to participate, pharmacists must have been trained by the Pennsylvania Pharmacists Care Network to deliver contracted comprehensive medication management services and willing to participate in audio recorded, telephonic interviews every 2 weeks. Interviews concluded when each pharmacist completed a total of 6 interviews or when the project period ended. A semistructured interview guide was developed by the investigators to elicit the pharmacists' experience providing contracted services. Interviews were transcribed and coded by 2 independent investigators. Coding discrepancies were resolved. The final coded transcripts were presented back to the project team to identify and finalize major themes. Illustrative quotes were selected to represent each theme. RESULTS: Interviews from 10 pharmacists were included in the analysis. Five themes emerged as keys of successful early implementation: (1) promote commitment of the pharmacy team, (2) use effective whole-team patient engagement strategies, (3) personalize patient encounters by providing patient-centered care and practicing interpersonal skills, (4) make workflow and staffing resources easily accessible, and (5) make clinical patient care tools readily available. CONCLUSION: These results highlight thematic trends for how pharmacists can successfully engage their patients in contracted comprehensive medication management services. Understanding the success of early implementation at a regional supermarket pharmacy can serve as a framework for other participants in community pharmacy enhanced services networks to replicate and scale contracted patient care services.

Assessment of the efficacy of commercially available and candidate vaccines against a pandemic H1N1 2009 virus.

BACKGROUND: The emergence and global spread of the pandemic H1N1 2009 influenza virus have raised questions regarding the protective effect of available seasonal vaccines and the efficacy of a newly produced matched vaccine. METHODS: Ferrets were immunized with the 2008-2009 formulations of commercially available live attenuated (FluMist; MedImmune) or split-inactivated (Fluviral; GlaxoSmithKline) vaccines, a commercial swine vaccine (FluSure; Pfizer), or a laboratory-produced matched inactivated whole-virus vaccine (A/Mexico/InDRE4487/2009). Adaptive immune responses were monitored, and the animals were challenged with A/Mexico/InDRE4487/2009 after 5 weeks. RESULTS: Only animals that received the swine or matched vaccines developed detectable hemagglutination-inhibiting antibodies against the challenge virus, whereas a T cell response was exclusively detected in animals vaccinated with FluMist. After challenge, all animals had high levels of virus replication in the upper respiratory tract. However, preexisting anti-pandemic H1N1 2009 antibodies resulted in reduced clinical signs and improved survival. Surprisingly, FluMist was associated with a slight increase in mortality and greater lung damage, which correlated with early up-regulation of interleukin-10. CONCLUSIONS: The present study demonstrates that a single dose of matched inactivated vaccine confers partial protection against a pandemic H1N1 2009 virus, and it suggests that a higher dose or prime-boost regimen may be required. The consequences of mismatched immunity to influenza merit further investigation.

Assessment of applied epidemiology competencies among the Virginia Department of Health workforce.

OBJECTIVES: Epidemiologists play critical roles in public health. However, until recently, no formal standards existed for epidemiology practice. In 2005, the Centers for Disease Control and Prevention and Council of State and Territorial Epidemiologists drafted Competencies for Applied Epidemiologists in Governmental Public Health Agencies (AECs) that provide a foundation for expectations and training programs for three tiers of practice. We characterized the Virginia Department of Health (VDH) epidemiology workforce and assessed its baseline applied epidemiology competency by using these competencies. METHODS: Epidemiologists representing multiple divisions developed an Internet survey based on the AECs. Staff who met the definition of an epidemiologist were requested to complete the survey. Within eight skill domains, specific competencies were listed. For each competency, frequency and confidence in performing and need for training were measured by using Likert scales. Differences among tier levels were assessed using analysis of variance. RESULTS: Eighty-eight people from 10 program areas responded and were included in the analysis. Median epidemiology experience was four years, with 52% having completed formal training. Respondents self-identified as Tier 1/entry-level (38%), Tier 2/mid-level (47%), or Tier 3/senior-level (15%) epidemiologists. Compared with lower tiers, Tier 3 epidemiologists more frequently performed financial or operational planning and management (p=0.023) and communication activities (p=0.018) and had higher confidence in assessment and analysis (p<0.001). Overall, training needs were highest for assessment/ analysis and basic public health sciences skills. CONCLUSIONS: VDH has a robust epidemiology workforce with varying levels of experience. Frequency and confidence in performing competencies varied by tier of practice. VDH plans to use these results and the AECs to target staff training activities.
