Effectiveness of Seasonal Malaria Chemoprevention in children under 10 years of age in Senegal: a stepped-wedge cluster-randomized trial

This study was done to determine the effectiveness of Seasonal Malaria Chemoprevention in Senegalese children up to 10 years of age using a stepped-wedge design. Outcomes included mortality, malaria cases treated as outpatients, severe malaria, and the prevalence of parasitaemia and anaemia, and adverse drug reactions. 54 health posts were randomized. 9 started implementation of SMC in 2008, 18 in 2009, and a further 18 in 2010, with 9 remaining as controls. In the first year of implementation SMC was delivered to children aged 3-59 months, the age range was then extended for the latter two years of the study to include children up to 10 years of age

inSCALE Baseline Cross-Sectional Survey Uganda

A data collection containing information on 6,501 children under 5 years of age in West Uganda. Data was collected during May - August 2011 as part of a baseline survey prior to implementation of the inSCALE c-RCT in the site. Dataset variables cover socioeconomic and demographic characteristics of households, symptoms of the most recent illness episode for the children during the two weeks preceding the survey, care seeking behaviour, treatments received and details of all self-reported out-of-pocket costs associated with care seeking for the episode of illness. Three datasets are made available: [1] The ‘inSCALE_baseline’ master table covers 1 child per row, and [2] a ‘inSCALE_long_baseline’ table with 1 illness condition per row (if child had more than one illness defined, one row is created for each illness) (5057 - only sick children included hence lower total), and [3] 'inSCALE_baseline_extra_cost' table containing additional data on household direct and indirect costs of care seeking collected in the baseline survey

A sectional curvature for statistical structures

A new type of sectional curvature is introduced. The notion is purely algebraic and can be located in linear algebra as well as in differential geometry.Comment: 19 page
