Discover cutting-edge methods, compelling scientific breakthroughs, and real-world applications spanning a wide range of disciplines.
This study examines microsampling devices for routine therapeutic drug monitoring-are we there yet. Although examples of patient self-sampling are rare at present, studies that evaluated feedback found it to be largely positive, revealing the feasibility of microsampling for TDM.
This study examines infliximab level between venous and capillary blood using novel device strongly correlate in paediatric inflammatory bowel disease patients. This is the first study in patients with PIBD to show that bloodspot technology is a patient friendly alternative method to measure IFX blood levels in PIBD.
This study examines green and sustainable drug analysis – combining microsampling and microextraction of drugs of abuse. A linear calibration model was found for all drugs but morphine.
This study examines feasibility of a noninterventional decentralized clinical trial model in adults with major depressive disorder. This study demonstrated that decentralized clinical trials can be performed in patients with stable MDD.
This study examines duration of SARS-CoV-2 sero-positivity in a large longitudinal sero-surveillance cohort, with a focus on the COVID-19 community research partnership. The short duration of antibody response suggests that the true population prevalence of prior SARS-CoV-2 infection may be significantly higher than presumed based on earlier sero-surveillance studies.
This study evaluated four volumetric dried-blood-spot devices for direct copper measurement using high-resolution continuum source graphite furnace atomic absorption spectrometry. All four supported accurate analysis, although device-specific blank variation affected uncertainty at very low copper concentrations.
This prospective study evaluated one-month clinical and functional outcomes after COVID-19 infection in US Military Health System beneficiaries. Hospitalization risk was associated with older age, obesity, and race or ethnicity, and many participants had not returned to normal activities after one month.
This study examines analytical method validation of doxorubicin and doxorubicinol in volumetric absorptive microsampling by liquid chromatography-tandem mass spectrometry.
This study examines alternative sampling devices to collect dried blood microsamples, with a focus on state-of-the-art. More extensive evaluation of these newly developed devices, not only analytically but also clinically, is needed to demonstrate their real-life applicability, which is a prerequisite for their use in the field of TDM.
This study characterized SARS-CoV-2 antibody responses for up to eight months after infection in New Zealand and demonstrated the feasibility of measuring anti-RBD IgG from finger-prick samples collected using Mitra. RBD and spike IgG responses remained relatively stable during follow-up.
