Five experiments are reported that demonstrate the use of the repetition discrimination task (RDT) to study perceptual grouping effects objectively and quantitatively. Experiments 1 and 3 validate the method by measuring grouping based on proximity, color similarity, common region, and element connectedness. Experiment 2 compares the RDT effects for proximity grouping to explicit subjective rat...
RDT is a graphical formal modelling language in which the modeller works by constructing diagrams of the processes in their model which they then join together to form complete systems. Aside from the benefits which accrue as a side effect of building a formal model of a proposed system, these diagrammatic models can be useful as a means of communication between the development team and the use...
Rapid diagnostic tests (RDTs) have transformed malaria diagnosis. The most prevalent P. falciparum RDTs detect histidine-rich protein 2 (PfHRP2). However, pfhrp2 gene deletions yielding false-negative RDTs, first reported in South America in 2010, have been confirmed in Africa and Asia. We developed a mathematical model to explore the potential for RDT-led diagnosis to drive selection of pfhrp2...
INTRODUCTION WHO now recommends test-based management of malaria (TBMM) across all age-groups. This implies artemisinin-based combination treatment (ACT) should be restricted to rapid diagnostic test (RDT)-positive cases. This is a departure from what caregivers in rural communities have been used to for many years. METHODS We conducted a survey among caregivers living close to 32 health cent...
BACKGROUND Intermittent screening and treatment (IST) of malaria during pregnancy has been proposed as an alternative to intermittent preventive treatment in pregnancy (IPTp), where IPTp is failing due to drug resistance. However, the antenatal parasitaemias are frequently very low, and the most appropriate screening test for IST has not been defined. METHODOLOGY/PRINCIPAL FINDINGS We conduct...
We demonstrate a Google Glass-based rapid diagnostic test (RDT) reader platform capable of qualitative and quantitative measurements of various lateral flow immunochromatographic assays and similar biomedical diagnostics tests. Using a custom-written Glass application and without any external hardware attachments, one or more RDTs labeled with Quick Response (QR) code identifiers are simultaneo...
BACKGROUND & OBJECTIVES Rapid diagnostic tests (RDTs) have become an essential surveillance tool in the malaria control programme in India. The current study aimed to assess the performance of ParaHIT-f, a rapid test in diagnosis of Plasmodium falciparum infection through detecting its specific antigen, histidine rich protein 2 (PfHRP-2), in Odisha State, India. METHODS The study was undertak...
OBJECTIVE To compare the diagnostic performance of microscopy using Giemsa-stained thick and thin blood smears to a rapid malaria dipstick test (RDT) in detecting P. falciparum malaria in Kenyan school children. DESIGN Randomised, controlled feeding intervention trial from 1998-2001. SETTING Rural Embu district, Kenya. The area is considered endemic for malaria, with four rainy seasons per ...
