BACKGROUND To investigate differences in the estimated minimum remaining dentin thickness (RDT) between periapical radiographs using the paralleling and parallax technique, after simulated removal of broken instrument from the mesiobuccal (MB) canal of maxillary first molar in virtual simulation model. The 3D measurement was taken as the standard for comparison. METHODS Thirty-six maxillary f...

Background In Papua New Guinea (PNG), a malaria treatment policy using rapid diagnostic tests (RDTs) plus artemisinin-based combination therapy (ACT) was widely introduced to rural communities in 2012. The objectives of the study were to evaluate the effect of this RDT/ACT introduction to a rural PNG population on health service utilization and to compare factors associated with health service ...

The detection of severe malaria in resource-constrained settings is often difficult because of requirements for laboratory infrastructure and/or clinical expertise. The aim of this study, therefore, was to explore the utility of a multiple antigen (HRP-2/pLDH) rapid diagnostic test (RDT) as a low-cost, surrogate marker of patients at high risk for complications of severe malaria. We reviewed pr...

INTRODUCTION Developments in rapid diagnostic tests (RDTs) have opened new possibilities for improved remote malaria diagnosis that is independent of microscopic diagnosis. Studies in some settings have tried to assess the influence of RDTs on the prescribing behaviour of health workers, but such information is generally lacking in Nigeria and many parts of sub-Saharan Africa. This study analys...

BACKGROUND Diagnosing Plasmodium falciparum malaria during pregnancy is a great challenge for clinicians because of the low density of parasites in the peripheral blood and parasite sequestration in the placenta. Nevertheless, few data on the use of malaria rapid diagnostic test (RDT) during pregnancy have been published. METHODS P. falciparum infections were assessed in 156 febrile pregnant ...

We propose an ambient communication system that modulates the reverberance applied to music with a single variable in order to communicate non-musical information to the listener. In order to assess the effectiveness of such a system, psychoacoustic tests of four subjects’ ability to discriminate changes in reverberant decay time (RDT) were conducted. Results indicate that human listeners are a...

BACKGROUND The aim of this study was to detect low parasite and asymptomatic malaria infections by means of three malaria diagnostic tests, in a low transmission region of Minab district, Hormozgan Province, southern Iran. METHODS Blood samples of 200 healthy volunteers from Bagh-e-Malek area were evaluated using microscopic, rapid diagnostic tests (RDT) and nested-PCR to inspect malaria para...

OBJECTIVE To assess the effect of renal denervation (RDT) on micro- and macro-vascular function in patients with heart failure with preserved ejection fraction (HFpEF). DESIGN A prospective, randomised, open-controlled trial with blinded end-point analysis. SETTING A single-centre London teaching hospital. PARTICIPANTS Twenty-five patients with HFpEF who were recruited into the RDT-PEF tr...

BACKGROUND Intermittent screening and treatment in pregnancy (ISTp) is a potential strategy for the control of malaria during pregnancy. However, the frequency and consequences of malaria infections missed by a rapid diagnostic test (RDT) for malaria are a concern. METHODS Primigravidae and secundigravidae who participated in the ISTp arm of a noninferiority trial in 4 West African countries ...
