Background: Information is scarce regarding the economic burden of respiratory syncytial virus (RSV) disease in low-resource settings. This study aimed to estimate the cost per episode of hospital admissions due to RSV severe disease in Argentina., Methods: This is a prospective cohort study that collected information regarding 256 infants under 12 months of age with acute lower respiratory tract infection (ALRTI) due to RSV in two public hospitals of Buenos Aires between 2014 and 2016. Information on healthcare resource use was collected from the patient's report and its associated costs were estimated based on the financial database and account records of the hospitals. We estimated the total cost per hospitalization due to RSV using the health system perspective. The costs were estimated in US dollars as of December 2022 (1 US dollar = 170 Argentine pesos)., Results: The mean costs per RSV hospitalization in infants was US$587.79 (95% confidence interval [CI] $535.24 - $640.33). The mean costs associated with pediatric intensive care unit (PICU) admission more than doubled from those at regular pediatric wards ($1,556.81 [95% CI $512.21 - $2,601.40] versus $556.53 [95% CI $514.59 - $598.48])., Conclusions: This study shows the direct economic impact of acute severe RSV infection on the public health system in Argentina. The estimates obtained from this study could be used to inform cost-effectiveness analyses of new preventive RSV interventions being developed., (© 2024. The Author(s).)

This survey was conducted in Greater Buenos Aires to assess the iron nutritional status of non-pregnant women of child-bearing age. One hundred and eighty-four subjects aged 16-44 years were studied. The prevalence of anaemia (haemoglobin concentration less than 120 g/l) was 25.8 per cent. According to the multiple criteria approach, 21.6 per cent of women presented two or three abnormal values of iron status indicators (free erythrocyte protoporphyrin, serum ferritin and/or mean corpuscular volume). Prevalences of anaemia were 19.2 per cent, 51.8 per cent and 100 per cent in women with 0-1, 2 or 3 indicators in the abnormal range, respectively. The haemoglobin shift analysis showed a prevalence of anaemia of 19.5 per cent. Frequency distribution of iron stores was calculated as described by Cook & Finch, with slight modifications; median value of iron stores was estimated at 180 mg iron. Depletion of iron stores was significantly associated with the socio-economic status, prevalences being 5.3 per cent, 34.2 per cent and 43.2 per cent for the high, middle and low socioeconomic groups, respectively.
