The effect of genetic and nongenetic factors on warfarin dose variability in Qatari population
Bader et al.
The finding, in our words
Using a patient-centric saliva microsampling kit, the study found that genetic variants, VKORC1 and CYP2C9, and smoking explained 39.2% of warfarin dose variability in a Qatari population, supporting decentralised sampling for pharmacogenomic profiling.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
In a one-week virtual home clinic with 134 participants, 86 per cent returned saliva and 84 per cent returned stool, and most components were feasible and acceptable despite device and logistical challenges. This supports decentralised, patient-centric self-collection of non-blood biospecimens for research.
This systematic review of 67 studies involving 34,739 kidney disease patients found dried blood microsampling was mainly used for immunosuppressant therapeutic drug monitoring and kidney function assessment. The approach offered cost savings, was preferred by patients for home self-collection, and provides a patient-centric opportunity to upscale longitudinal sampling and reduce participation bias in decentralised kidney disease research.

Self-collected saliva samples provided adequate DNA for genotyping in preterm birth research, though questionnaire data on birth details had limited concordance with prospective records, indicating that while DNA sampling is feasible via post, phenotyping requires more reliable data collection methods for genetic studies.
Using the Oragene DNA self-collection kit, this study found no significant difference in CNTFR genotype frequencies between weightlifters, 56% CC, 32% CT and 12% TT, and controls, 53% CC, 40% CT and 7% TT. However, the CT+TT genotype was associated with higher relative performance, though the cross-sectional design limits causal inference.

Among 148 Marshallese adults recruited through community-based participatory research, 95.5% provided a 2 mL saliva specimen using an Oragene DNA self-collection kit and 96.6% agreed to future contact, demonstrating high acceptability of patient-centric, decentralised genetic sampling in an underserved population with disproportionate type 2 diabetes burden.
