Reproducibility and implementation of a rapid, community-based COVID-19 "test and respond" model in low-income, majority-Latino communities in Northern California.

OBJECTIVE: To evaluate implementation of a community-engaged approach to scale up COVID-19 mass testing in low-income, majority-Latino communities. METHODS: In January 2021, we formed a community-academic "Latino COVID-19 Collaborative" with residents, leaders, and community-based organizations (CBOs) from majority-Latinx, low-income communities in three California counties (Marin/Merced/San Francisco). The collaborative met monthly to discuss barriers/facilitators for COVID-19 testing, and plan mass testing events informed by San Francisco's Unidos en Salud "test and respond" model, offering community-based COVID-19 testing and post-test support in two US-census tracts: Canal (Marin) and Planada (Merced). We evaluated implementation using the RE-AIM framework. To further assess testing barriers, we surveyed a random sample of residents who did not attend the events. RESULTS: Fifty-five residents and CBO staff participated in the Latino collaborative. Leading facilitators identified to increase testing were extended hours of community-based testing and financial support during isolation. In March-April 2021, 1,217 people attended mass-testing events over 13 days: COVID-19 positivity was 3% and 1% in Canal and Planada, respectively. The RE-AIM evaluation found: census tract testing coverage of 4.2% and 6.3%, respectively; 90% of event attendees were Latino, 89% had household income <$50,000/year, and 44% first-time testers (reach), effectiveness in diagnosing symptomatic cases early (median isolation time: 7 days) and asymptomatic COVID-19 (41% at diagnosis), high adoption by CBOs in both counties, implementation of rapid testing (median: 17.5 minutes) and disclosure, and post-event maintenance of community-based testing. Among 265 non-attendees surveyed, 114 (43%) reported they were aware of the event: reasons for non-attendance among the 114 were insufficient time (32%), inability to leave work (24%), and perceptions that testing was unnecessary post-vaccination (24%) or when asymptomatic (25%). CONCLUSION: Community-engaged mass "test and respond" events offer a reproducible approach to rapidly increase COVID-19 testing access in low-income, Latinx communities.

Suspected COVID-19-related reticulated purpura of the soles in an infant.

A growing number of skin lesions during the COVID-19 pandemic are being recognized. Acral ischemic lesions identical to chilblains are most typical in children and young adults. We report an infant girl, aged 1 month and 29 days, with a peculiar reticulated purpuric eruption on her soles, with positive immunohistochemistry for SARS-CoV-2 in the endothelia of dermal blood vessels. The patient had an excellent outcome without specific therapy.

Evaluaciòn nutricional de una variedad de chorizo de carne y otra de chorizo de pescado / Nutritional evaluation of a variety of meat sausage and another one of fish sausage

Se realizó un estudio de 2 nuevos productos elaborados con tecnologías similares y que difieren en sus materias primas. Se compara la composiciòn de nutrientes de ambos productos con sus especificaciones de calidad, así como la calidad de las proteinas por un balance de nitrógeno en ratas. La composición de nutrientes de ambas muestras responden a las especificaciones establecidas para este tipo de producto. Se observó diferencia significativa en la digestabilidad, no así en el valor biológico, la utilización neta de la proteína y la relación de eficiencia proteíca
