Summary
Transcription errors in lipid variables occurred in the VIPVIZA study. An educational intervention reduced these errors, but some still impacted cardiovascular disease risk predictions.
Area of Science:
- Medical Research
- Clinical Data Management
- Cardiovascular Disease Risk Assessment
Background:
- The VIPVIZA study involves transcribing lipid parameters (total cholesterol, triglycerides, HDL, LDL) into a research database.
- Transcription errors can occur during this data entry process, potentially affecting downstream analyses and clinical decisions.
Purpose of the Study:
- To quantify transcription errors in lipid variables within the VIPVIZA study.
- To evaluate the effectiveness of an educational intervention in reducing these transcription errors.
- To assess the impact of transcription errors on the SCORE2 cardiovascular disease risk prediction algorithm.
Main Methods:
- Lipid parameters were transcribed by research nurses.
- Transcription errors were identified by recalculating LDL cholesterol; a difference >0.15 indicated an error.
- The SCORE2 risk category was compared using both incorrect and correct lipid values to assess misclassification.
Main Results:
- The transcription error frequency was 0.55% in 2019, decreasing to 0.25% in 2023 after an educational intervention.
- Among individuals with transcription errors in total or HDL cholesterol, 15% were assigned an incorrect SCORE2 risk category.
Conclusions:
- Transcription errors in clinical data persist despite digitalization efforts.
- Minimizing manual transcriptions outside the laboratory is crucial for data accuracy.
- Accurate lipid values are essential for reliable cardiovascular risk prediction algorithms like SCORE2.

Viral Mutations
32.1K
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Leaky Scanning
5.1K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

Proofreading
6.1K
Synthesis of new DNA molecules is carried out by the enzyme DNA polymerase, which adds nucleotides on the daughter strand complementary to the template DNA strand. DNA polymerase has a higher affinity to add the correct base and ensures fidelity during DNA replication. Furthermore, it exhibits proofreading activity during replication, using an exonuclease domain that cuts off incorrect nucleotides from the nascent DNA strand.

Genome Copying Errors
4.1K
DNA replication is a well-evolved process that copies millions of base pairs with high fidelity during each cell division. Occasionally a wrong base or a long stretch of wrong bases may get added to the daughter strands. If the errors are left unchecked, cells might accumulate several mutations that might endanger their survival. Therefore, the copying errors are checked and repaired at three levels.

Transcription Attenuation in Prokaryotes
15.1K
Transcriptional attenuation occurs when RNA transcription is prematurely terminated due to the formation of a terminator mRNA hairpin structure. Bacteria use these hairpins to regulate the transcription process and control the synthesis of several amino acids including histidine, lysine, threonine, and phenylalanine. Transcription attenuation takes place in the non-coding regions of mRNA.
