RESUMEN
Description The COVID-19 pandemic has intensified the existing health and social disparities that affect minority groups in the United States (US), including the Latinx community. This situation has been reflected in many aspects of health, including increased morbi-mortality and reduced adherence to medical and scientific recommendations. Limited access to health care, financial challenges, migrant status, and health literacy, or lack thereof, have all hampered the Latinx community's ability to seek aid quickly and to be tested or treated effectively for this disease. This pandemic has shown that the Latinx community's socioeconomic status correlates with greater mortality rates when compared to other ethnic groups, which runs counter to historical norms. Furthermore, morbi-mortality in Latinx people has been disproportionately greater. Beyond the systematic barriers that the Latinx community has had to face to access care during the pandemic, there were also perception barriers that increased the gap and further complicated the situation. Latinxs were more likely to be exposed due to a decreased compliance with physical distancing. When it was suggested to avoid crowds, many people started using delivery services; however, many Latinxs found the cost and requirements of reliable internet to be a barrier to using these services. Currently, COVID-19 vaccines are broadly available in the US but there has been skepticism from marginalized communities, including the Latinx population, about getting vaccinated. Integrating this population into a welcoming healthcare system, safeguarding their immigration and work status, providing more accessible vaccination locations, and promoting health equality and education would all assist to lessen the impact of this illness on the Latinx community.
RESUMEN
A 47-year-old woman with Rosai-Dorfman disease (RDD) presented with an electrical storm with sustained ventricular tachycardia. Echocardiography and computed tomography revealed an intracardiac mass involving the right atrium and left ventricle. Positron emission tomography demonstrated fluorodeoxyglucose avidity of the mass and myocardial infiltration; the electrical storm was attributed to this feature. Cardiac involvement in RDD is extraordinarily rare, and this appears to be the first report of an association of this disease with an electrical storm.

No intuito de comparar os resultados apresentados na literatura de várias técnicas de segmentaçäo de microcalcificaçöes mamográficas, selecionamos as técnicas que aparentemente apresentavam os melhores resultados a saber: 'threshold', crescimento de regiäo e filtros gaussianos combinados com operadores morfológicos. Processamos as imagens, de um mesmo banco de dados, digitalizadas com o mesmo dispositivoe comparamos os resultados obtidos. Além disso baseados nesta comparaçäo desenvolvemos um algorítmo híbrido que aproveita parte das técnicas mais eficientes apresentadas para segmentar as microcalcificaçöes com um desempenho superior.
