BACKGROUND: The use of rapid amplification methods to detect pathogens in biological samples is mainly limited by the amount of pathogens present in the sample and the presence of inhibiting substances. Inhibitors can affect the amplification efficiency by either binding to the polymerase, interacting with the DNA, or interacting with the polymerase during primer extension. Amplification is performed using DNA polymerase enzymes and even small changes in their activity can influence the sensitivity and robustness of molecular assays Methods: The main purpose of this research was to examine which compounds present in urine inhibit polymerases with strand displacement activity...

BACKGROUND: Solana® (Quidel) is a new rapid (<40 min.) point-of-care (POC) test for qualitative detection of Trichomonas vaginalis (TV) DNA. The assay has two steps: 1) specimen preparation, and 2) amplification and detection using isothermal Helicase-Dependent Amplification (HDA). The objective was to demonstrate the performance of Solana for vaginal swabs and female urines based on comparison to wet mount and TV culture. Performance was also compared to the Aptima-TV assay. METHODS: Urine and four clinician-collected vaginal swabs were collected...

The HIV pandemic affects 36.7 million people worldwide, predominantly in resource-poor settings. Nucleic acid-based molecular detection of HIV plays a significant role in antiretroviral treatment monitoring for HIV patients, as well as diagnosis of HIV infection in infants. Currently available molecular diagnostic methods are complex, time-consuming and relatively expensive, thus limiting their use in resource-poor settings. Recent advances in microfluidics technology have made possible low-cost integrated miniaturized devices for molecular detection and quantification of HIV at the point of care...

BACKGROUND & AIMS: Chronic liver diseases (CLD) are highly frequent and thus mainly managed by non-hepatologists. Because they lack access to the best non-invasive tests of liver fibrosis, these physicians cannot accurately determine the disease severity and the need for referral to a hepatologist. We aimed to implement an algorithm, comprising a new first-line test usable by all physicians, for the detection of advanced liver fibrosis in all CLD patients. METHODS: Diagnostic study: 3,754 CLD patients with liver biopsy were 2:1 randomized into derivation and validation sets...

What does it take to mobilise experiences of care and make them useful for improving services? This article draws on ethnographic fieldwork with a UK-based patient feedback website to develop a critical perspective on patient experience as a contingent accomplishment and a focal point for eliciting, provoking, and respecifying relations of accountability. Following a single posting from the moderation room back to the author and into the wards and offices of the hospital, I show how moderators, carers, and clinical staff respond to and act upon a seemingly stable experience...

Enormous progress has been made in recent years toward effectively treating and curing patients with chronic hepatitis C (CHC). However, at least half of the possible 7 million individuals infected with hepatitis C virus (HCV) in the US remain undiagnosed. The formidable task of increasing the number of patients diagnosed, and subsequently linked to appropriate care has fallen to primary care clinicians, who are mandated by some US States to offer screening to individuals born between 1945 and 1965 (the Baby Boomer Generation)...

BACKGROUND: Several tools have been developed to measure safety attitudes of health care providers, out of which the Safety Attitudes Questionnaire (SAQ) is regarded as one of the most appropriate ones. In 2007, it was adapted to outpatient (primary health care) settings and in 2014 it was tested in out-of-hours health care settings in Norway. The purpose of this study was to translate the English version of the SAQ-Ambulatory Version (SAQ-AV) to Slovenian language; to test its reliability; and to explore its factor structure...

BACKGROUND: Because of the low sensitivity of conventional rapid diagnostic tests (RDTs) for malaria infections, the actual prevalence of the diseases, especially those caused by non-Plasmodium falciparum (non-Pf) species, in asymptomatic populations remain less defined in countries lacking in well-equipped facilities for accurate diagnoses. Our direct blood dry LAMP system (CZC-LAMP) was applied to the diagnosis of malaria as simple, rapid and highly sensitive method as an alternative for conventional RDTs in malaria endemic areas where laboratory resources are limited...

BACKGROUND: Clinical guidelines support decision-making at the point-of-care but the onus is often on individual users such as physicians to implement them. Research shows that the inclusion of implementation tools in or with guidelines (GItools) is associated with guideline use. However, there is little research on which GItools best support implementation by individual physicians. The purpose of this study was to investigate naturalistic access and use of GItools produced by the American Academy of Neurology (AAN) to inform future tool development...

PURPOSE OF REVIEW: Recent advances in point-of-care technologies to ensure universal access to affordable quality-assured diagnostics have the potential to transform patient management, surveillance programmes, and control of infectious diseases. Decentralization of testing can put tremendous stresses on fragile health systems if the laboratory is not involved in the planning, introduction, and scale-up strategies. RECENT FINDINGS: The impact of investments in novel technologies can only be realized if these tests are evaluated, adopted, and scaled up within the healthcare system with appropriate planning and understanding of the local contexts in which these technologies will be used...

PURPOSE OF REVIEW: More point-of-care (POC) diagnostic tests are becoming available for HIV diagnosis and treatment in resource-limited settings. These novel technologies have the potential to foster decentralized HIV care and treatment for the benefit of clinical laboratories, HIV clinics, and HIV-infected patients. There continue to be many business, technological, and operational challenges that limit product development and regulatory approval, which limits products available for the required operational and cost-effectiveness studies and delays policy adoption and implementation...

In low-resource settings, where qualified health workers (HWs) are scarce and childhood mortality high, rational antimicrobial prescription for childhood illnesses is a challenge. To assess whether smartphones running guidelines, as compared with paper support, improve consultation process and rational use of medicines for children, a pilot cluster-randomized controlled study was conducted in Tanzania. Nine primary health-care facilities (HFs) were randomized into three arms: 1) paper algorithm, 2) electronic algorithm on a smartphone, and 3) control...

Purpose There is a lack of high-level evidence identifying meaningful outcomes and the optimal place in therapy of rasburicase in patients with, or at high risk for tumor lysis syndrome. The primary objective of this study was to evaluate and characterize outcomes resulting from an institution-specific guideline emphasizing supportive care, xanthine oxidase inhibitors, and lower doses of rasburicase. Methods In this retrospective chart review, we compared conservative rasburicase dosing, in accordance with newly developed UMHS tumor lysis syndrome guidelines, with aggressive rasburicase in adult patients (≥ 18 years of age) with hematological or solid tumor malignancies, and a uric acid level between 8 and 15 mg/dL...
