The challenge of conducting epidemiological research in times of pandemic and denialism: 1-year anniversary of the EPICOVID-19 project in Brazil
As of 20 May 2021, Brazil was the country with the second-highest number of COVID-19 deaths and the third-highest number of COVID-19 cases in absolute numbers in the world. In relative numbers, on 20 May 2021, the 7-day daily rolling average of deaths was 9.08 per million people in Brazil. From the beginning of the pandemic until 20 May 2021, the Brazilian cumulative mortality rate was 2078 per million inhabitants. In late 2020, Manaus, a state capital in the heart of the Amazon region, experienced chaos as oxygen supplies were depleted and intensive care unit (ICU) occupancy exceeded 100%, generating waiting lists. A coup...

Reflection on modern methods: shared-parameter models for longitudinal studies with missing data
This article outlines one of the three primary recognized approaches for examining missing-data effects that could be more widely used, i.e. the shared-parameter model (SPM), and explains its purpose, use, limitations and extensions. We additionally provide synthetic data and reproducible research code for running SPMs in SAS, Stata and R programming languages to facilitate their use in practice and for teaching purposes in epidemiology, biostatistics, data science and related fields. Our goals are to increase understanding and use of these methods by providing introductions to the concepts and access to helpful tools. (So...

Syndromic surveillance using monthly aggregate health systems information data: methods with application to COVID-19 in Liberia
ConclusionsSyndromic surveillance can be used to monitor health facility catchment areas for spikes in specific symptoms which may indicate SARS-CoV-2 circulation. The developed methods coupled with the existing infrastructure for routine health data systems can be leveraged to monitor a variety of indicators and other infectious diseases with epidemic potential.

bootComb —an R package to derive confidence intervals for combinations of independent parameter estimates
AbstractMotivationTo address the limits of facility- or study-based estimates, multiple independent parameter estimates may need to be combined. Specific examples include (i) adjusting an incidence rate for healthcare utilisation, (ii) deriving a disease prevalence from a conditional prevalence and the prevalence of the underlying condition, (iii) adjusting a seroprevalence for test sensitivity and specificity. Calculating combined parameter estimates is generally straightforward, but deriving corresponding confidence intervals often is not. bootComb is an R package using parametric bootstrap sampling to derive such interv...

Exposure to breastfeeding and risk of developing multiple sclerosis
ConclusionOur study could not confirm previous findings of an association between breastfeeding and risk of MS. Breastfeeding information was less likely to be biased by knowledge of disease compared with case –control studies. (Source: International Journal of Epidemiology)
