Given the well-documented failings in mathematics education in many Western societies, there has been an increased interest in understanding the cognitive underpinnings of mathematical achievement. Recent research has proposed the existence of an Approximate Number System (ANS) which allows individuals to represent and manipulate non-verbal numerical(More)
BACKGROUND Clinical management of Ebola virus disease remains challenging. Routine laboratory analytics are often unavailable in the outbreak setting, and few data exist for the associated haematological and biochemical abnormalities. We aimed to assess laboratory and clinical data from patients with Ebola virus disease to better inform clinical management(More)
BACKGROUND Despite the huge burden of HIV in sub-Saharan Africa, there is little evidence of the multidimensional needs of patients with HIV infection to inform the person-centred care across physical, psychological, social and spiritual domains stipulated in policy guidance.

AIM This study investigated the diagnostic accuracy of the Strengths and Difficulties Questionnaire (SDQ) in a population of children born extremely preterm (<26wks gestation). METHOD Parents and teachers of 219 extremely preterm children (118 females, 101 males; age 11y) were asked to complete the SDQ to screen for psychological problems. Multi-informant(More)
OBJECTIVE To estimate the prevalence of epilepsy in Rwanda, as part of a survey of musculoskeletal impairment (MSI). METHODS Cross-sectional nationally representative survey. Clusters of 105 people were selected with probability proportional to size, using the 2002 national census as the sampling frame. Within each cluster, 80 people were selected through(More)
OBJECTIVES To assess whether the trachoma vector Musca sorbens was breeding in household latrines in a trachoma-endemic part of The Gambia. METHODS Longitudinal study of flies emerging from 16 sentinel household latrines selected at random from a list of all latrines present in four Gambian villages. Latrines were surveyed and fly traps were set over the(More)
All households in 32 villages were provided with improved pit latrines as part of a trachoma control programme in a rural part of The Gambia. Latrine provision was externally driven and was not in response to a request from the communities involved. Materials were provided for free and labour was paid for. To assess durability and acceptability we conducted(More)
BACKGROUND Children born very preterm (<32 wk) are at high risk for mathematics learning difficulties that are out of proportion to other academic and cognitive deficits. However, the etiology of mathematics difficulties in very preterm children is unknown. We sought to identify the nature and origins of preterm children's mathematics difficulties. (More)
