Web-Enabled Distributed Health-Care Framework for Automated Malaria Parasite Classification: an E-Health Approach.

Web-Enabled Distributed Health-Care Framework for Automated Malaria Parasite Classification: an E-Health Approach. J Med Syst. 2017 Oct 26;41(12):192 Authors: Maity M, Dhane D, Mungle T, Maiti AK, Chakraborty C Abstract Web-enabled e-healthcare system or computer assisted disease diagnosis has a potential to improve the quality and service of conventional healthcare delivery approach. The article describes the design and development of a web-based distributed healthcare management system for medical information and quantitative evaluation of microscopic images using machine learning approach for malaria. In the proposed study, all the health-care centres are connected in a distributed computer network. Each peripheral centre manages its' own health-care service independently and communicates with the central server for remote assistance. The proposed methodology for automated evaluation of parasites includes pre-processing of blood smear microscopic images followed by erythrocytes segmentation. To differentiate between different parasites; a total of 138 quantitative features characterising colour, morphology, and texture are extracted from segmented erythrocytes. An integrated pattern classification framework is designed where four feature selection methods viz. Correlation-based Feature Selection (CFS), Chi-square, Information Gain, and RELIEF are employed with three different classifiers i.e. Naive Bayes', C4.5, and Instance-Based Learning (IB1) indiv...

AbstractMalaria, an important parasitic disease worldwide, still has diagnostic challenges in the laboratory. Many studies have been conducted on the detection ability of haematology analysers for malaria. We evaluated the Sysmex XN-series analyser as a tool for detection of malaria by analysing the leukocyte cell population data (LCPD), scattergrams and associated Flow Cytometry Standard (FCS) data from both the WNR (white cell nucleated) and WDF (white cell differential) channels. 1281 clinically suspected cases of malaria were screened for malaria by peripheral blood smear examination and were run in the Sysmex XN-1000 ...

ConclusionsOur study confirmed thatP. falciparum is the dominant species in the sahelian zone and that malaria transmission is seasonal and associated with rainfall in this zone. The application of the current national policy based on rapid and reliable malaria diagnosis, case management with artemisinin-based combination therapy, intermittent preventive treatment for pregnant women, distribution and use of long-lasting insecticide impregnated bed nets, and the planned introduction of seasonal malaria chemoprevention for all children under 6  years old is expected to sustainably reduce malaria transmission in this zone.

We present a low-cost alternative and complementary solution for rapid malaria screening for low resource settings to potentially reduce the dependence on manual microscopic examination. We develop an image processing pipeline using a modified YOLOv3 detection algorithm to run in real time on low-cost devices. We test the performance of our solution on two datasets. In the dataset collected using a microscope camera, our model achieved 99.07% accuracy and 97.46% accuracy on the dataset collected using a mobile phone camera. While the mean average precision of our model is on par with human experts at an object level, we ar...

We present here a retrospective comparative study for RDT and PCR (nested and high-resolution-melting quantitative PCR [HRM-qPCR]) evaluation of ACPR in a nonendemicity context. Blood samples from 133 patients presenting a Plasmodium falciparum monoinfection were included. Samples obtained at the time of diagnosis and at 3, 7, and 28 days after diagnosis were investigated. Histidine-rich protein 2 (HRP-2)-based RDT results remained positive in 51% of cases 28 days after diagnosis and appropriate therapeutic management. Parasite DNA was detected by the two PCR techniques (nested PCR and HRM-qPCR) in 12% and 10% of samples 2...

Abstract Malaria endemicity in Cameroon greatly varies according to ecological environment. In such conditions, parasitaemia, which is associated with fever, may not always suffice to define an episode of clinical malaria. The evaluation of malaria control intervention strategies mostly consists of identifying cases of clinical malaria and is crucial to promote better diagnosis for accurate measurement of the impact of the intervention. We sought out to define and quantify clinical malaria cases in children from three health districts in the Northern region of Cameroon. A cohort study of 6,195 children aged betwee...

Conclusion: Metabolite extract of S. hygroscopicus subsp. hygroscopicus causes morphological damage, decreases the degree of parasite-infected erythrocytes and the DNA density of P. falciparum 3D7 in vitro. PMID: 31673263 [PubMed]

AbstractMalaria is caused byPlasmodium parasite. It is transmitted by femaleAnopheles bite. Thick and thin blood smears of the patient are manually examined by an expert pathologist with the help of a microscope to diagnose the disease. Such expert pathologists may not be available in many parts of the world due to poor health facilities. Moreover, manual inspection requires full concentration of the pathologist and it is a tedious and time consuming way to detect the malaria. Therefore, development of automated systems is momentous for a quick and reliable detection of malaria. It can reduce the false negative rate and ...

Authors: Camarlinghi G, Parisio EM, Nardone M, Mancini F, Ciervo A, Boccolini D, Mattei R Abstract Both malaria and relapsing fever Borrelia are infectious diseases characterized by fever, headache, myalgia, hepatosplenomegaly and tendency to relapse. Exflagellation of microgametocyte in malarial parasites is seen only in the definitive host, i.e., mosquitoes. Here we report an unusual case of a 23-year-old man who presented Plasmodium vivax infection with multiple exflagellated microgametes in the peripheral blood smear.

This week's case presents a bit of a conundrum. The patient is a 50 year old woman with recent travel to Kenya. She presents with acute onset of fever and chills and was tested by a rapid malaria antigen test (P. falciparumand Pan-malaria antigens) and was negative. A follow-up Giemsa-stained thin blood smear from the same blood collection shows the following:Identification based on the blood smear? How might this correlate with the rapid antigen test?

Answer toParasite Case of the Week 558:Plasmodium falciparummalaria,>10% parasitemia. NEGATIVE rapid antigen.Sowhy is the rapid antigen test negative???As noted by our readers, there are many possible reasons for apositive blood smear and negative rapid malaria antigen test (RDT). Here are our options, along with the reasons why each is or isn't a likely explanation in this case:This is babesiosis, and not malaria. This is a very important consideration given the morphologic similarities betweenBabesiaspp. andPlasmodium falciparum.However, the moprhologic features in this case are highly consistent withP. falciparu...
