RESUMO
OBJECTIVES: The main objective was to determine the prevalence of recurrent wheezing (RW) among infants and toddlers as well as the prevalence of asthma predictive risk factors among those with RW. MATERIALS AND METHODS: A prospective study of a cohort of babies recruited after their birth during July 2015-June 2017. Mothers were contacted using the WhatsApp messaging system for digital follow-up on their baby's condition at 3-monthly intervals until they were 18 months old. Information on wheezing and its correlates were collected by digital follow-up and corroborated at an in-person interview and examination of their baby at 18 months of age. Recurrent wheezing was defined as more than three episodes of wheezing or its correlates during the follow-up period. RESULTS: There were 338 males (41.5%) and 476 (58.5%) females. Overall, 31.1% (95% CI = 27.9%, 34.4%) had RW by 18 months and the same number had RW during their first year of life. Of the infants with RW, 121 (47.8%; 95% CI = 41.6, 54.2) had at least one or both of the major criteria and/or at least two minor criteria of the stringent Asthma Predictive Index (API). Of those with RW, 32.0% received antihistamine and 20% had received antibiotics on their last visit to a physician for wheezing or symptoms of cough, cold, and/or breathing difficulty. CONCLUSIONS: Nearly a third of infants and toddlers had RW and nearly half of the infants with RW had risk factors fulfilling the criteria of the stringent API.

BACKGROUND: Prior to implementation of a national surveillance system for cardiovascular disease in Barbados, a small island state with limited health resources, the national burden of acute myocardial infarction (MI) was unknown. METHODS: We retrospectively estimated national acute MI incidence rates (IRs) per 100,000 during the decade before registry implementation (1999-2008), using easily accessible routine data from different sources, assessing changes over time through Poisson regression. Future events (2009-2013) were estimated using simple sensitivity analysis to incorporate prediction uncertainty. Model predictions were compared with actual IRs from initial years of the registry. RESULTS: In 2000, crude IR was 85.5 (95% CI: 74.9-97.2), rising to 92.1 (81.2-103.9) in 2008. Accounting for population ageing, the model anticipated IR of 115.9 in 2010 (99.7-132.1), vs actual crude IR 129.7 (115.9-144.6). CONCLUSIONS: Despite no electronic medical record system in Barbados, data were simple to collect, and provided a rough baseline for acute MI burden. We show that, in countries with small populations, limited resources and in absence of surveillance, national mortality statistics and routine hospital data can be combined to adequately model national estimates of acute MI incidence. This cheap and simple, yet fairly accurate method could be a key tool for other low-resource countries with ageing populations and increasing cardiovascular disease levels.
