NCT ID: NCT03512678 Completed - Malaria Clinical Trials

Evaluation of a Digital Microscope for Malaria

EasyScanGo
Start date: June 25, 2018
Phase:
Study type: Observational

Light microscopy, which is based on century-old technology, remains a key indicator in drug efficacy testing performed in the context of clinical trials for monitoring existing antimalarial drugs or in the context of regulatory clinical trials for registration of new drugs. It is one of the main diagnostic methods for malaria diagnosis in general, as in an ideal setting it can provide low-cost accurate diagnosis, determine the density of parasites in the blood, and accurately differentiate between different malaria parasite species, characteristics vital to the implementation of global plans for drug efficacy monitoring. Malaria rapid tests (RDTs), while useful for rapid diagnosis and case management, do not provide information on the parasite density nor the species differentiation necessary for research and drug efficacy assessment. Microscopy therefore retains key advantages over a number of newer technologies, but its reliability is severely impeded by dependence on high technical competence of the human operators as well as availability of high quality equipment and reagents. Recent studies have demonstrated frequent poor specificity and sensitivity associated with manual microscopy diagnostics in operational conditions. These drawbacks constitute a major limiting factor to effective monitoring and preservation of vital anti-malarial medicines. Advances in digital microscopy performance and affordability have now opened the door to potentially significant improvements in the performance of malaria microscopy, overcoming serious deficiencies in current drug efficacy assessment, and more broadly in malaria diagnosis and management. Global Good (GG)/Intellectual Ventures Laboratory (IVL) sponsored by the Global Good Fund, has developed a microscope prototype consisting of low cost components to scan and capture images from Giemsa-stained thick blood films on slides. The captured images are analyzed with custom image analysis software developed at GG/IVL, using algorithms that are designed for automatic malaria diagnosis, without user input. Versions of a prototype of the device were first tested in field settings in Thailand in 2014-2015 at clinics operated by the Shoklo Malaria Research Unit (SMRU) and then again in 2016-2017. When compared to expert microscopy at SMRU, the performance of the device with respect to diagnostic sensitivity (87.8%), species identification (85.6% species correctly identified) and parasite density estimation (44% of estimates within +/-25% of reference microscopy result) corresponded to WHO Competence Level 2. The device and the accompanying image analysis algorithms have since been further developed and a new, third version of the prototype is now available for testing in diverse settings with varying malaria prevalence and user expertise.

NCT ID: NCT03512210 Completed - Hepatitis C Clinical Trials

Monitoring SOF/VEL in Treatment Naïve, HCV Participants With Active Infection

MINMON
Start date: October 22, 2018
Phase: Phase 4
Study type: Interventional

To achieve global hepatitis C virus (HCV) elimination by 2030, 80% of the ~71 million people with chronic HCV infection will need to be treated, necessitating simplification of treatment delivery and associated laboratory monitoring without compromising efficacy or safety. The COVID-19 pandemic has further highlighted the need for innovative models of health care delivery that minimize face-to-face patient-provider contact. The purpose of this study was to evaluate the feasibility, safety, and efficacy of a minimal monitoring (MINMON) strategy to deliver interferon- and RBV-free, pan-genotypic DAA therapy to treat active HCV in HCV treatment naïve participants.

NCT ID: NCT03512093 Completed - Preterm Birth Clinical Trials

Improving SCBU Care for Preterm Babies

PretermBabies
Start date: May 1, 2018
Phase:
Study type: Observational

Since 2008, preterm neonates are taking care of in a Special Baby Care Unit (SCBU). Those born less than 34 weeks of gestation are followed-up monthly for one year for monitoring their hematocrit level, growth and development. Medical chart reviews are useful to evaluate the burden of diseases, characterize care treatment patterns and clinical outcomes by patients' subgroups; ultimately it can help identifying gaps in care pathways thus improving quality of care and ultimately reducing mortality. Medical records of all preterm neonates hospitalized in the SCBU including those followed up during their first year of life are computerized. The investigators propose to review the clinical charts of the preterm neonates in regards to four main points of care a) feeding, b) infections including early onset of neonatal sepsis, necrotizing enterocolitis and umbilical cord infection, c) body temperature control and d) respiratory distress. This medical charts review will be complemented by i) focus group discussions (FGD) with the medical staff working in the SCBU on the benefits and difficulties in using the existing guidelines for preterm care and by ii) interviews with mothers who delivered a preterm neonate on their experience in caring for their child and the challenges they faced. While performing the retrospective part of the project and after discussing the preliminary findings from the medical staff perception of the existing guidelines, the investigators will evaluate the feasibility to implement some additional recommendations to improve preterm birth outcomes based on recent literature and new protocols for resource-limited settings.

NCT ID: NCT03510013 Completed - Anesthesia Clinical Trials

NCT ID: NCT03498300 Completed - Pregnancy Related Clinical Trials

Seroprevalence of Bordetella Pertussis Antibodies and Anti-pertussis Antibody Response After a Single Dose of Tdap in Pregnant Thai Women

Start date: May 9, 2018
Phase: Early Phase 1
Study type: Interventional

This study evaluated the seroprevalence of Bordetella pertussis antibodies and anti-pertussis antibody response after a single dose of reduced-antigen, combined diphtheria, tetanus, and acellular pertussis vaccine (Tdap) in pregnant Thai women. All seronegative participants received Tdap, while seropositive participants were equally randomized into 2 groups. Half of seropositive participants received Tdap and the other half received tetanus-diphtheria (Td) as standard protocol.

NCT ID: NCT03484312 Completed - Clinical trials for Hypertension on Emergence

Hypertensive Urgency Treatment and Outcomes in a Northeast Thai Population

Start date: January 1, 2012
Phase:
Study type: Observational [Patient Registry]

Previous studies have reported a high prevalence of hypertensive (HT) urgency. However, these studies have also reported low rates of serious complications, suggesting that rapid blood pressure (BP) reduction may be unnecessary. There are limited clinical data available on this topic in Asian populations. The investigators aimed to determine the basic characteristics, treatment methods, and outcomes in HT urgency patients, both in the emergency room (ER) and at a two-week follow-up.
