Regression Toward the Mean

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...

Comparing Copy Number Variations and SNPs

Comparing Copy Number Variations and SNPs

Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Development of the Oral Microbiota

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Genomic Imprinting and Inheritance

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Overview of the Reproductive System

Overview of the Reproductive System

The reproductive system generates offspring, ensuring the survival of the species. In humans, the reproductive system is complex and involves a variety of organs and hormones that work together to ensure successful reproduction.
The gonads, or primary reproductive organs, produce gametes and sex hormones. In males, the testes produce spermatozoa and testosterone, which is responsible for developing secondary male sex characteristics, including a deeper voice, larger muscles, facial and body...

Area of Science:

Clinical Epidemiology
Pharmacovigilance
Reproductive Health

Background:

Epilepsy and pregnancy registries have operated for over a decade, accumulating substantial data on antiepileptic drug (AED) use during pregnancy.
Published findings from different registries highlight the need to assess the comparability of their observations, given methodological variations.

Purpose of the Study:

To facilitate information exchange on methodologies among major epilepsy and pregnancy registries.
To identify potential areas for harmonization in data collection and analysis across registries.
To discuss the comparability of findings from the UK Epilepsy and Pregnancy Register, North American AED Pregnancy Registry (NAAPR), and EURAP.

Main Methods:

A workshop was convened in September 2008 involving representatives from key international epilepsy and pregnancy registries.
Discussions focused on comparing the methodologies employed by the UK Epilepsy and Pregnancy Register, NAAPR, and EURAP.
The report summarizes the outcomes of these discussions regarding methodological differences and harmonization possibilities.

Main Results:

The workshop facilitated a direct exchange of information regarding the operational methodologies of participating registries.
Key differences and similarities in data collection and analytical approaches were identified.
Areas where methodological harmonization could enhance data comparability were explored.

Conclusions:

Comparative analysis of epilepsy and pregnancy registry data is crucial due to methodological variations.
Harmonization efforts among registries like the UK Epilepsy and Pregnancy Register, NAAPR, and EURAP are essential for robust pharmacovigilance.
Further collaboration is needed to standardize approaches for improved understanding of AED safety in pregnancy.
