In order to demonstrate an intake of cannabis, there are a number of rapid tests, all of them being focused on urine. In this study, we evaluated the results of six tests when applied to sweat (DrugWipe), saliva and urine (Syva Rapidtest, Biomedix, Frontline, DrugWipe, Cortez Dako). Fifty regular users of cannabis and fifty persons who denied consuming it were studied. The results obtained with DrugWipe in sweat were compared with anamnesis data, whereas results obtained in saliva and urine were compared with those of gas chromatography--mass spectrometry. The results indicate that DrugWipe may be useful for screening cannabis in sweat when the intake took place less than two hours before. The results obtained in saliva showed that none of the tests studied are reliable to be used with this medium, because of the great number of false positive and false negative results. With urine, four tests (Syva Rapidtest, Biomedix, Cortez, Dako) led to very good results and may be recommended when an immediate presumptive test result is required.

Persistent infection with high-risk human papillomavirus (hrHPV) is a major cause of cervical cancer. The effectiveness of current HPV-DNA testing, which is crucial for early detection, is limited in several aspects, including low sensitivity, accuracy issues, and the inability to perform comprehensive hrHPV typing. To address these limitations, we introduce MTIOT (Multiple subTypes In One Time), a novel detection method that utilizes machine learning with a new multichannel integration scheme to enhance HPV-DNA analysis.

Background: PROTECT ( Platform Randomised evaluation of clinical Outcomes using novel TEChnologies to optimise antimicrobial Therapy) has brought together a team of researchers to design a platform trial to rapidly evaluate and adopt into care multiple diagnostic technologies, bringing immediate benefit to patients. Rapid diagnostic tests will be used to identify patients at risk of deterioration from severe infection, before they become critically unwell. The platform will assess their comparative clinical effectiveness and cost-effectiveness relative to current standard of care.

Background: Guillain-Barré syndrome (GBS) is a rapid-onset disease caused by the immune system damaging the peripheral nervous system. Since most standardized treatments for GBS focus on acute phase treatment, there are limitations to the rehabilitation and management of general conditions. In East Asian countries, herbal medicine has been used to treat GBS and aid rehabilitation.

The overuse of antibiotics has led to the severe contamination of water bodies, posing a considerable hazard to human health. Therefore, the development of an accurate and rapid point-of-care testing (POCT) platform for the quantitative detection of antibiotics is necessary. In this study, Cerium oxide (CeO) and Ferrosoferric oxide (FeO) nanoparticles were simultaneously encapsulated into N-doped nanofibrous carbon microspheres to form of a novel nanozyme (CeFe-NCMzyme) with a porous structure, high surface area, and N-doped carbon material properties, leading to a considerable enhancement of the peroxidase (POD)-like activity compared with that of the CeO or FeO nanoparticles alone.

Development of sustainable synthesis methods of organic electrode materials (OEMs) for sodium (Na)-ion batteries must take hold rapidly in large scale-synthesis if subsequent commercialisation is to occur. We report a facile and rapid gram-scale synthesis method based on microwave irradiation for disodium naphthalene-2,6-dicarboxylate (Na-NDC) and mono/disodium benzene-1,4-dicarboxylate (Na-BDC) as model compounds. Phase purity and formation of materials was confirmed by various characterisation techniques.
