BACKGROUND In malaria endemic areas, infected blood donors serve as a source of infection to blood recipients, which may adversely affect their prognosis. This necessitates the proper screening of blood to be used for transfusion in these areas. The purpose of this study was to determine the prevalence of malaria parasitaemia in blood donors in Buea, Cameroon, and to evaluate the performance of...

The damping ratio is a key indicator of structures susceptability to human discomfort due dynamic loads. Computational models, wind tunnel studies and empirical data can provide estimates the structure. However, only true way investigate structure through modal identification using from field tests carried out on full-scale finished This paper investigates efficacy three methods for estimating ...

The Pastorex((R)) (BioRad) rapid agglutination test is one of the main rapid diagnostic tests (RDTs) for meningococcal disease currently in use in the "meningitis belt". Earlier evaluations, performed after heating and centrifugation of cerebrospinal fluid (CSF) samples, under good laboratory conditions, showed high sensitivity and specificity. However, during an epidemic, the test may be used ...

BACKGROUND Malaria rapid diagnostic tests (RDTs) have great potential to improve quality care and rational drug use in malaria-endemic settings although studies have shown common RDT non-compliance. Yet, evidence has largely been derived from limited hospital settings in few countries. This article reviews a PhD thesis that analyzed national surveys from multiple sub-Saharan African countries t...

BACKGROUND The World Health Organization (WHO) considers early and rapid diagnosis as one of the strategies to control malaria. This study compared the performance of Quantitative Buffy Coat (QBC) test and the Plasmodium lactate dehydrogenase (pLDH) rapid diagnostic test (RDT) with microscopy as the gold standard. MATERIALS AND METHODS The study involved children ages 0-5 years who presented ...

UNLABELLED We evaluated the sensitivity for the anti-HIV antibody detection of the 8 rapid disposable tests (RDTs) EC approved in 2008. METHODS A panel of 100 native serum samples collected from HIV-1 subtype B or non-B, HIV-1 group O or HIV-2-infected patient and 3 commercial seroconversion panels were tested. 50 sera from HIV-negative patients were included to blind reading and RDT specific...

This study investigated the comparative accuracy of a recombinant 56-kDa type-specific antigen-based rapid diagnostic test (RDT) for scrub typhus for the detection of IgM antibodies by using conventional serology in well-characterized serum samples from undifferentiated febrile illness patients. The RDT showed high specificity and promising comparative accuracy, with 82% sensitivity and 98% spe...

In the decision-making and rationality research field, Rational Decision Theory (RDT) has always been the main framework, thanks to the elegance and complexity of its mathematical tools. Unfortunately, the formal refinement of the theory is not accompanied by a satisfying predictive accuracy, thus there is a big gap between what is predicted by the theory and the behavior of real subjects. Here...

We recently established a unique therapeutic modality for musculoskeletal sarcomas, combining acridine orange (AO) with photodynamic surgery (PDS), photodynamic therapy (PDT) and radiodynamic therapy (RDT); excellent results were obtained in the inhibition of local tumor recurrence after intralesional excision. However, AO is not yet approved for clinical use and intravenous injection. Therefor...

Case history The patient was a 47-year-old housewife who began RDT in March 1972, at which time she was oedematous, her blood urea was 250 mg/100 ml, her creatinine 22 mg/100 ml and her haemoglobin 5 9 g%. Six weeks after the onset of RDT when the patient's physical condition had improved and her predialysis blood urea was 170 mg/100 ml and her creatinine 14-5 mg/100 ml, she became hypomanic. F...
