Filter by:Since their introduction in the late 90's, rapid diagnostic tests (RDTs) have markedly improved our ability to control malaria; yet they have inherent limitations which include low sensitivity in Plasmodium vivax detection and inability to detect hrp2/3 gene deleted Plasmodium falciparum parasites. In addition, the spread of P. falciparum parasites lacking hrp2 gene jeopardizes the long-term use of P. falciparum-specific HRP2-based RDTs. A partnership between RapiGEN, FIND, and the Bill and Melinda Gates Foundation (BMGF) is addressing these limitations by developing five novel malaria RDTs with improved pLDH and HRP2 detection. RapiGEN has also developed three novel malaria RDTs - BIOCREDIT Malaria Ag Pf/Pv (pLDH/pLDH), BIOCREDIT Malaria Ag Pf (pLDH/HRP2) and BIOCREDIT Malaria Ag Pf (pLDH) - to address these drawbacks. The BIOCREDIT Malaria Ag Pf/Pv (pLDH/pLDH) is a combo test that detects P. falciparum and P. vivax on a single device. BIOCREDIT Malaria Ag Pf (pLDH/HRP2) targets both PfLDH and HRP2 antigens in P. falciparum; and BIOCREDIT Malaria Ag Pf (pLDH) has improved detection of pLDH in P. falciparum. In countries with circulation of hrp2/3 deleted P. falciparum malaria parasites or high P. vivax burden, these improved RDTs may be invaluable in malaria elimination. This study is a prospective and retrospective evaluation of RapiGEN's BIOCREDIT Malaria Ag RDTs in malaria-endemic countries to assess their clinical performance for detection of malaria. The purpose of this study is to provide a high level outline of the study design and conduct to support the collation of a data package for WHO Pre-Qualification proposed study.
This study is to compare the feasibility and test performance of different 3D pelvic ultrasound and Transrectal ultrasound in the detection of local lesions in the uterus , cervix and vagina compared to the final diagnosis confirmed by vaginoscopy as a golden standard modality of diagnosis in Virgin Patients
The purpose of this study is to determine the reliability of a low-cost rapid diagnostic test for COVID-19. The method of the testing procedure uses electrochemistry to detect COVID-19 spike proteins within human samples. To test the effectiveness of this new method, patients will be recruited as they present for testing at ambulatory Penn testing sites. Patients will be asked to self-collect one anterior nares samples under the supervision of authorized study personnel.
Survey-based satisfaction, performance and technical features evaluation of a speech-enabled fixed-phrase translation tool (BabelDR) in an emergency department.
This study serves as a validation study for the Omnyx Dynamyx software and Hamamatsu .ndpi image file format, evaluating agreement of diagnosis between whole slide images (WSI) of the Omnyx system (Omnyx scanned .rts images and Omnyx Dynamyx software) and the Omnyx Dynamyx software with the Hamamatsu .ndpi images. The primary goal of this study is to demonstrate concordance between the two systems to validate the Omnyx Dynamyx software with the non-Omnyx .ndpi image file type.
this study will determine the effect of CBCT examinations on diagnostic and therapeutic decision making in endodontics.
In this retrospective observational case study, the investigators review the clinical experience with pressure-pain algometry in children with suspected appendicitis. The investigators hypothesized that algometry can discriminate children with appendicitis from children without appendicitis and aimed to determine the diagnostic accuracy of algometry, compared to ultrasound imaging and clinical assessment.
This is a prospective randomized single-blind simulator-based trial. 156 4th year medical students were randomised to receive one of three different suspected diagnoses of a pre-treating physician (no diagnosis, myocardial infarction, pulmonary embolism) prior to the task to make a focussed assessment and perform first management steps in a patient presenting to the emergency department. The patient (simulator) suffered from an acute myocardial infarction. Video recordings were obtained during simulation and used for data analysis. Primary endpoint was the participants' final presuptive diagnosis.
Amino acids (AAs) are organic molecules that are associated with inflammation and innate immunity diseases with critical roles in the cell repair and protection process. Our aim was to identify the free amino acids in saliva of a group of periodontitis patients and healthy individuals and additionally to assess their levels in different periodontal disease types and compare it to the healthy individuals.
Studies suggest that the timing interval between oral intake and the 1-hour gestational diabetes screen may have a significant impact on gestational diabetes screening glucose levels. The investigators plan to conduct a prospective randomized trial comparing a 6-hour fast versus liberal oral intake within 2 hours prior to the glucose tolerance test in pregnancy in order to evaluate the effect of the fasting versus the fed state on routine gestational diabetes screening results.
