An Overview of Online Resources for Medical Spanish Education for Effective Communication with Spanish-Speaking Patients.

PHENOMENON: Despite the rapid development of virtual medical Spanish educational materials, online resources lack transparency and a peer-review process. The purpose of this interdisciplinary study was to provide a critical inventory of virtual resources for medical Spanish education, thereby providing a panorama of the current state of online medical Spanish. APPROACH: Research team members conducted iterative searches to identify medical Spanish online resources, which were then screened for predetermined inclusion/exclusion criteria. Between June and August 2020, a panel of medical and language experts then adapted and applied a previously published evaluation tool to determine whether resources that met study criteria would help learners achieve medical Spanish core competencies and to what extent each resource incorporated communicative language activities. Consensus meetings were conducted to resolve disagreements and identify gaps in online education. FINDINGS: Out of 465 resources, 127 were further screened, and eight were selected for evaluation. Medical and language specialists independently scored each resource and, following discussions, achieved consensus. Overall, no resource met suitability criteria for all five medical Spanish learner competencies or cultural elements, and only one was suitable for achieving the self-assessment competency. INSIGHTS: Interdisciplinary consensus meetings provide an important avenue for resolving differences of opinion and for integrating both language and medical perspectives into the evaluation process. Existing online resources should be used in conjunction with other materials to ensure that all core competencies for medical Spanish education are addressed. This study revealed important gaps in online resources, including a need to target advanced Spanish learners, apply authentic communicative activities, include assessment opportunities, and integrate culture in the learning program. Based on the current state of online medical Spanish, we offer recommendations for future resources.

Implementation of a pragmatic randomized trial of screening for chronic kidney disease to improve care among non-diabetic hypertensive veterans.

BACKGROUND: Whether screening for chronic kidney disease (CKD) can improve the care of persons at high risk for complications remains uncertain. We describe the design and early implementation experience of a pilot, cluster-randomized pragmatic trial to evaluate the feasibility, implementation, and effectiveness of a "triple marker" CKD screening program (creatinine, cystatin C and albumin to creatinine ratio) for improving care among hypertensive veterans seen in primary care at one Veterans Administration Hospital. METHODS/DESIGN: Non-diabetic hypertensive veterans age 18-80 without known CKD were randomized in clusters determined by primary care provider (unit of randomization) into three arms. Usual care will be compared with two incrementally intensified treatment strategies: (1) screen for CKD followed by patient and provider education or (2) screen-educate plus a clinical pharmacist-led CKD and BP management program. The primary clinical outcome is systolic blood pressure (BP) change from baseline. Secondary clinical outcome is BP control. The primary process outcomes is triple marker screening (across three arms), and secondary process outcomes include use of inhibitors of the renin-angiotensin system (ACE/ARB) overall and in persons with albuminuria, CKD recognition by PCP, use of non-steroidal anti-inflammatory drugs (NSAIDs) and NSAID education by PCP. The design uses the Veterans Health Administration electronic health record (EHR) to identify participants, deliver the interventions and ascertain study outcomes. Assessment of the program implementation will use the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. Study duration is 12 months. RESULTS: A total of 1,819 patients have been randomized within 41 provider clusters. The median age (interquartile range) is 68 years (61-72), and 99% of participants are male. Approximately 16% are Black, and 5% Hispanic. In the first 6 months of the trial, 434 triple marker screening tests have been ordered, and 217(50%) have been tested. A total of 48 new CKD cases have been identified among those tested, for a preliminary yield of 22%. CONCLUSION: We have successfully implemented a pragmatic protocol that uses the EHR to identify and characterize eligible participants, deliver the intervention, and ascertain study outcomes with high rates of participation by providers and patients. Results from this study can guide design of pragmatic trials in the field of CKD. TRIAL REGISTRATION: NCT01978951 ; Date or Registration: 1/17/2014.

Genetic diversity of Aedes aegypti in the central-upper Paraná Cross-Border axis in Paraguay. / Diversidad genética de aedes aegypti en el eje transfronterizo Central-Alto Paraná en Paraguay.

OBJECTIVE: To determine the genetic diversity of Aedes aegypti in the Central-Alto Paraná cross-border road corridor of Paraguay, an area that has reports of dengue cases. MATERIALS AND METHODS: Twenty adult females were selected from hatching Ae. aegypti eggs from households geolocated in the departments of Alto Paraná, Caaguazú, Cordillera and Central, between 2018 and 2019. DNA was extracted from the tissue of females for amplifying their polymorphic patterns by random amplification of polymorphic DNA by PCR (RAPD-PCR), using primers H3 and B03 in order to identify genetic parameters of population diversity. The relationships between mosquito populations according to locality were observed by unpaired arithmetic mean analysis. We used DIVA-GIS 7.3.0 and MAXENT to analyze the suitable areas of actual and potential geographic distribution of these Ae. aegypti populations. RESULTS: Forty loci were identified by RAPD-PCR profiling, with moderate gene differentiation (Gst = 0.12). The cross-border corridor presented bioclimatic conditions for the presence of variant populations of Ae. aegypti, with precipitation in the warmest quarter and mean temperature in the driest quarter being determinant in the distribution. CONCLUSIONS: There is evidence of moderate genetic diversity in Ae. aegypti populations from areas that have reported dengue cases in the cross-border road corridor linking the Central and Alto Paraná departments of Paraguay. The study of genetic variability of Ae. aegypti is very useful for entomo-epidemiological surveillance and evaluation of possible resistance to chemical control.

OBJETIVOS: Conocer la diversidad genética de Aedes aegypti en el corredor vial transfronterizo Central-Alto Paraná de Paraguay, con registros de casos de dengue. MATERIALES Y MÉTODOS: Se seleccionaron veinte hembras adultas de la eclosión de huevos de Ae. aegypti procedentes de casas geolocalizadas en los departamentos de Alto Paraná, Caaguazú, Cordillera y Central, entre el 2018 y 2019. Se extrajo ADN del tejido de las hembras para amplificación aleatoria de sus patrones polimórficos mediante amplificación aleatoria del ADN polimórfico por PCR (RAPD-PCR), usando cebadores H3 y B03 a fin de conocer parámetros genéticos de diversidad poblacional. Las relaciones entre las poblaciones de mosquitos según la localidad fueron visualizadas mediante análisis no apareado de la media aritmética. Las áreas idóneas de distribución geográfica real y potencial de estas poblaciones de Ae. aegypti fueron analizadas mediante DIVA-GIS 7.3.0 y MAXENT. RESULTADOS: Se identificaron 40 loci mediante perfiles RAPD-PCR, con diferenciación génica moderada (Gst = 0,12). El corredor transfronterizo presentó condiciones bioclimáticas para la presencia de poblaciones variantes de Ae. aegypti, siendo determinantes en la distribución la precipitación del trimestre más cálido y la temperatura media del trimestre más seco. CONCLUSIONES: Se evidencia que existe diversidad genética moderada en las poblaciones de Ae. aegypti procedentes de zonas con registros de casos de dengue ubicadas en el corredor vial transfronterizo que une los departamentos Central y Alto Paraná de Paraguay. El estudio de variabilidad genética de Ae. aegypti es de gran utilidad para la vigilancia entomoepidemiológica y evaluación de posibles eventos de resistencia al control químico.

Screening for CKD To Improve Processes of Care among Nondiabetic Veterans with Hypertension: A Pragmatic Cluster-Randomized Trial.

BACKGROUND AND OBJECTIVES: We conducted a pilot, pragmatic, cluster-randomized trial to evaluate feasibility and preliminary effectiveness of screening for CKD using a triple-marker approach (creatinine, cystatin C, and albumin/creatinine ratio), followed by education and guidance, to improve care of hypertensive veterans in primary care. We used the electronic health record for identification, enrollment, intervention delivery, and outcome ascertainment. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We randomized 1819 veterans without diabetes but with hypertension (41 clusters) into three arms: (1) CKD screening followed by patient and provider education; (2) screening, education, plus pharmacist comanagement; or (3) usual care. The primary clinical outcome was BP change over 1 year. Implementation and process measures included proportion screened; CKD detection rate; and total and new use of renin-angiotensin system inhibitors, nonsteroidal anti-inflammatory drugs, and diuretics. RESULTS: Median age was 68 years, 55% were white, 1658 (91%) had a prior creatinine measure, but only 172 (9%) had prior urine albumin/creatinine ratio, and 83 (5%) had a prior cystatin C measure. Among those in the intervention, 527 of 1215 (43%) were identified with upcoming appointments to have CKD screening. Of these, 367 (69%) completed testing. Among those tested, 77 (21%) persons had newly diagnosed CKD. After 1 year, change in systolic BP was -1 mm Hg (interquartile range, -11 to 11) in usual care, -2 mm Hg (-11 to 11) in the screen-educate arm, and -2 mm Hg (-13 to 10) in the screen-educate plus pharmacist arm; P=0.49. There were no significant differences in secondary outcomes in intention-to-treat analyses. In as-treated analyses, higher proportions of participants in the intervention arms initiated a renin-angiotensin system inhibitor (15% and 12% versus 7% in usual care, P=0.01) or diuretic (9% and 12% versus 4%, P=0.03). CONCLUSIONS: The pragmatic design made identification, enrollment, and intervention delivery highly efficient. The limited ability to identify appointments resulted in inadequate between-arm differences in CKD testing rates to determine whether screening improves clinical outcomes.
