Biosensors based on converting electrochemical signals into optical readouts are attractive candidates as low-cost, high-throughput sensor platforms. Here, we described a closed bipolar electrode (CBE)-based two-cell electrochromic device for sensing multiple metabolites, using the simultaneous detection of lactate, glucose, and uric acid as a model system. In the two-cell configuration, an analytical cell contains a redox mediator combined with a specific oxidase, e.g., lactate oxidase, glucose oxidase, or uricase, to form an electrochemical mediator-electrocatalyst pair that supports redox cycling...

OBJECTIVES: Community-acquired pneumonia (CAP) is associated with a high risk of respiratory failure or septic organ dysfunction. Lactate is an established early marker of prognosis and sepsis severity, but few data exist in patients with CAP. METHODS: We performed a retrospective cohort study of consecutive adult CAP patients without treatment restrictions or direct ICU admission. Lactate was measured as point of care test within the capillary admission blood gas analysis and its prognostic value was compared to the CRB/CURB-65 criteria by multivariate and ROC curve analysis...

BACKGROUND: Visual assessment of burn wound appearance is the standard of care to determine the depth of thermal injury but often incorrectly predicts wound healing potential. Histologic evaluation of hematoxylin and eosin (H&E) stained burn tissue is prone to subjectivity and is challenging for the novice. Lactate dehydrogenase (LDH) staining may offer a simplified and consistent technique to identify burn tissue viability. METHODS: Thirty tissue samples were obtained from six patients undergoing surgical excision for clinically determined deep partial thickness or full thickness burns...

Aptamer-based biosensing, which uses short, single-stranded nucleic acid segments to bind to a target, can be advantageous over antibody-based diagnostics due to the ease of synthesis and high stability of aptamers. However, the development of most aptamer-based sensors (aptasensors) is still in its initial stages and many factors affecting their performance have not been studied in great detail. Here, we enhance the sensing specificity of a fluorescence resonance energy transfer (FRET)-based MoS2 nanosheet aptasensor in detecting the malarial biomarker Plasmodium lactate dehydrogenase (pLDH)...

Sepsis represents a global health problem in terms of morbidity, mortality, social and economic costs. Although usually managed in Intensive Care Units, sepsis showed an increased prevalence among Internal Medicine wards in the last decade. This is substantially due to the ageing of population and to multi-morbidity. These characteristics represent both a risk factor for sepsis and a relative contra-indication for the admission to Intensive Care Units. Although there is a lack of literature on the management of sepsis in Internal Medicine, the outcome of these patients seems to be gradually improving...

INTRODUCTION: During military deployment, the diagnosis and the management of acute bacterial meningitis can be problematic, as deployed Medical Treatment Facilities (MTFs) often have a limited laboratory diagnostic capability. However, French Role 2 and 3 MTFs have point-of-care (POC) testing to perform urinary (Multistix 10 SG strip) and blood (iSTAT handheld analyser) biochemical testing mentioned in AMedP8.5. The purpose of this study was to compare the accuracy of this urine test strip and of the iSTAT CHEM8 and CG4 cartridges with a standard hospital bench top analyser in order to determine if these POC devices have a potential role in the biochemical analysis of cerebrospinal fluid (CSF protein, CSF glucose and CSF lactate, respectively)...

This commentary serves to raise health care provider awareness about the regulatory status and available evidence regarding domperidone for insufficient lactation. Breastfeeding provides significant health benefits for mothers and infants, and insufficient milk production remains the most common reason for early weaning. Domperidone, a dopamine receptor antagonist that may increase milk production, is not approved for any human use in the United States. It is approved in some countries for certain gastrointestinal disorders, but is not approved in any country for lactation enhancement...

BACKGROUND: Dyspnea is a frequent complaint in emergency departments (ED). It has a significant amount of subjective and affective components, therefore the dyspnea scores, based on the patients' rating, can be ambiguous. Our purpose was to develop and validate a simple scoring system to evaluate the severity of dyspnea in emergency care, based on objectively measured parameters. METHODS: We performed a double center, prospective, observational study including 350 patients who were admitted in EDs with dyspnea...
