Enny S. Paixao and colleagues estimate excess all-cause mortality in children under five years with congenital syphilis compared to those without congenital syphilis in Brazil.

The older population is prone to microbial infections, which can lead to death. Hence, it is important to understand why this group is vulnerable to microbial infection, especially bacterial infection. A recent Scientific Reports study linked data from two sources to understand the determining factors for microbial infection in the older population in the UK.

This paper proposes an instrumental variable regression estimator of population totals using a sample, a set of links between the sample units and records on an administrative file, and a set of calibration totals calculated from the administrative file. This paper proposes a survey-weighted estimator of a population total that is valid when the survey non-response mechanism is non-ignorable and false negatives occur in the administrative-survey linkage. False negatives lead to measurement error...

Researchers assessed the intensity of association between SARS-CoV-2 infection and risks of various respiratory and non-respiratory complications.

In a study of linked population-based data, Enny Paixao and colleagues study the associations between cesarean section and child mortality among 17.8 million live births in Brazil.
