This observational study examined whether injection-needle length and skin-to-muscle distance affected antibody responses after mRNA COVID-19 vaccination. Antibody levels were comparable across needle-sufficiency groups, but the specific product used for the finger-prick blood collection is not identified in the abstract and requires confirmation.
This study investigated the instability of acetylsalicylic acid in VAMS samples under different drying conditions. Controlling humidity increased recovery above 85%, and a household vacuum sealer offered a practical approach for stabilizing patient-collected samples at home.
Researchers optimized digestion and analysis of the aflatoxin B1–lysine biomarker and developed a reference material to support method comparison. VAMS samples produced results equivalent to serum, supporting dried microsampling for public-health exposure studies.
This study adapted quantitative SARS-CoV-2 serology assays for self-collected finger-stick blood and saliva. Both sample types identified prior immune responses with high specificity, and saliva remained stable for five days, supporting scalable mail-based testing.
This longitudinal North Carolina study used repeated at-home serology and symptom reporting to estimate accumulated SARS-CoV-2 infection and vaccine response. Seropositivity exceeded documented case counts and rose sharply after vaccination began, especially among healthcare workers.
Researchers measured SARS-CoV-2 antibodies in healthcare workers before and during early vaccination. Seroprevalence rose with community infection and vaccination, while workplace role and ICU duties were associated with higher infection risk.
This prospective study modeled midazolam pharmacokinetics in critically ill and control pediatric patients. Acute inflammation, cardiovascular impairment, and weight significantly affected clearance, with simulations indicating a substantial overdose risk under current dosing in some critically ill children.
This study developed and clinically validated a single VAMS–UPLC-MS/MS assay for tacrolimus, mycophenolic acid, and creatinine in renal-transplant recipients. The method supported one-sample remote monitoring of both immunosuppressant exposure and kidney function and was preferred by patients over dried blood spots.
This protocol describes a population-based longitudinal study of SARS-CoV-2 infection, immunity, and long-term outcomes in a rural Italian district. Repeated questionnaires, viral testing, antibody monitoring, and existing molecular and genetic data were designed to characterize infection determinants and sequelae.
Researchers developed a VAMS–LC-MS/MS method for 24 tryptophan-related metabolites and biomarkers in small murine blood samples. The assay was sensitive, precise, stable for 30 days at room temperature, and suitable for disease-mechanism and therapeutic-intervention studies.
