Assessment of the quality of Primary Health Care in Fortaleza, Brazil, from the perspective of adult service users in 2019.

Primary Health Care (PHC) is the "front door" and keystone of Brazil's public health system, meaning that the evaluation of the quality of primary care services is of utmost importance. Using the Primary Care Assessment Tool (PCAT), this study evaluated the performance of public PHC services in Fortaleza from the view of adult service users. We conducted a cross-sectional study of 233 adult service users from 19 primary care centers (PCCs) between June and December 2019, collecting data on the sociodemographic and epidemiological characteristics of users and structural features of PCCs.

Modeling the progression of COVID-19 deaths using Kalman Filter and AutoML.

The COVID-19 pandemic continues to have a destructive effect on the health and well-being of the global population. A vital step in the battle against it is the successful screening of infected patients, together with one of the effective screening methods being radiology examination using chest radiography. Recognition of epidemic growth patterns across temporal and social factors can improve our capability to create epidemic transmission designs, including the critical job of predicting the estimated intensity of the outbreak morbidity or mortality impact at the end.
