RESUMO

Providing communities with COVID-19 vaccination information is essential for optimizing equitable vaccine uptake. Using rapid community translation, adapted from Boot Camp Translation, five community teams transcreated COVID-19 vaccination campaigns. Transcreated messaging incorporated community attitudes, culture, and experiences. Using rapid community translation for the promotion of COVID-19 vaccination demonstrates a successful approach to engaging communities most affected by the pandemic to develop messages that reflect community values, assets, and needs, especially when time is of the essence.

RESUMO

Genomic selection (GS) is revolutionizing conventional ways of developing new plants and animals. However, because it is a predictive methodology, GS strongly depends on statistical and machine learning to perform these predictions. For continuous outcomes, more models are available for GS. Unfortunately, for count data outcomes, there are few efficient statistical machine learning models for large datasets or for datasets with fewer observations than independent variables. For this reason, in this paper, we applied the univariate version of the Poisson deep neural network (PDNN) proposed earlier for genomic predictions of count data. The model was implemented with (a) the negative log-likelihood of Poisson distribution as the loss function, (b) the rectified linear activation unit as the activation function in hidden layers, and (c) the exponential activation function in the output layer. The advantage of the PDNN model is that it captures complex patterns in the data by implementing many nonlinear transformations in the hidden layers. Moreover, since it was implemented in Tensorflow as the back-end, and in Keras as the front-end, the model can be applied to moderate and large datasets, which is a significant advantage over previous GS models for count data. The PDNN model was compared with deep learning models with continuous outcomes, conventional generalized Poisson regression models, and conventional Bayesian regression methods. We found that the PDNN model outperformed the Bayesian regression and generalized Poisson regression methods in terms of prediction accuracy, although it was not better than the conventional deep neural network with continuous outcomes.

RESUMO

Abstract Introduction Indolent or chronic mucormycosis is a rare entity that affects both immunosuppressed and immunocompetent individuals. Additionally, its clinical evolution is nonspecific and there is no standardized treatment for this condition. Objective To describe the clinical characteristics and management of patients with indolent mucormycosis. Methods In the project of study with chart review in the Interinstitutional secondary care centers, patients with evidence of indolentmucormycosis, defined as pathological confirmation of nasal/paranasal sinus mucormycosis for more than 1 month, were included. All patients underwent complete laboratory workup, imaging studies, surgical treatment and adequate follow-up. No evidence of disease status was defined when patient had subsequent biopsies with no evidence of mucormycosis. Results We included seven patients, three female and four male subjects. The mean age was 53.14 years. Four patients were immunosuppressed and three immunocompetent. Among the immunosuppressed patients three had diabetes and one had dermatomyositis. The symptomswere nonspecific: facial pain/headache, mucoid discharge and cacosmiawere the ones most frequently reported. Maxillary sinus involvement was present in all patients. Two immunosuppressed subjects received amphotericin. Posaconazole was the only treatmentinoneimmunosuppressedpatient. Allimmunocompetent patientshadsingleparanasal sinus disease and received only surgical treatment. All patients are alive and free of disease. Conclusion Indolent mucormycosis is a new and emerging clinical entity in immunosuppressed and immunocompetent patients. Single paranasal sinus disease is a frequent presentation and should not be overlooked as a differential diagnosis in these patients. Immunocompetent patients should only be treated surgically.

RESUMO

Se realizó un estudio prospectivo en 76 recién nacidos con asfixia perinatal en busca de isquemia miocárdica encontrándose en 51% de ellos. El diagnóstico se realizó con electrocardiograma y se complemetó con enzimas cardiacas, rayos X y datos clínicos. No hubo diferencia en cuanto a sexo; la edad gestacional promedio fué de 35 semanas y el peso promedio de 2,216 g; todos presentaron insuficiencia respiratoria ameritando ventilación mecánica asistida. El 20.5% mostró cardiomegalia, en la mayoría se encontró CPK-MB (fracción cardiaca de CPK) elevada a las 48 horas de vida. La patología de fondo fué el síndrome de dificultad respiratoria en 38%, como enfermedad asociada encefalopatía hipóxica-isquémica en 59% y hemorragia peri-intrventricular en 33%. Fallecieron 33% de los pacientes. Se realizó también un estudio comparativo entre los niños con y sin isquemia miocárdica encontrando diferencias significativas, y considerándose como factores de riesgo a: 1. Cardiomegalia, 2. Encefalopatía hipóxica-isquémica y 2. CPK-MB elevada.
