Study Notes
Sex Differences in Pharmacokinetics
- In more than 90% of cases, female participants suffered worse adverse drug reactions (ADRs) than men when given the same dosage, regardless of sex.
- ADRs experienced by women include nausea, headaches, drowsiness, depression, excessive weight gain, cognitive deficits, seizures, hallucinations, agitation, and cardiac anomalies.
- Analysis of 86 different drugs in over 5,000 articles reveals that pharmacokinetics can predict sex differences in ADRs.
Gender Bias in Clinical Trials
- In 2011, a review of clinical trials found that 75% did not report any outcomes by sex, including 9 studies with less than 20% of female participants.
- A cross-sectional study of over 43,000 published articles and 13,000 clinical trials found female participants were substantially underrepresented, especially in international research on HIV/AIDS, chronic kidney diseases, and cardiovascular diseases.
Eliminating Gender Bias
- Royal Free London research has eliminated gender bias in liver transplantations by using a more accurate measure of renal function, specifically in patients with cirrhosis.
- The previous creatinine score used was not accurate for women due to their lower muscle mass, which led to a disadvantage in liver transplantation prioritization.
Genomic Equity
- Studying diverse populations is crucial to understanding how genetic variation influences our response to diet, infection, and different health conditions.
- The Human Heredity and Health in Africa (H3Africa) consortium uncovered 3 million previously undescribed DNA variants from 426 African individuals, many of which are linked to various conditions.
- A 2020 Nature article found that 45 of 58 studies using data from the UK biobank excluded data from specific populations, and 31 of the studies gave no reason for these exclusions.
Genomic Data and Research
- The UK approach to genomic research aims to build databases with better representation, integrate genomics into clinical practice, and publish research with clear reasons for exclusion.
- The NHS Genomic Medicine Service plans to analyze 500,000 genomes by 2023/24, which will help improve genetic representation and reduce bias in research and clinical analysis.
Ethical Considerations
- The Human Genome Project presented complex ethical issues, including privacy, confidentiality, and access to genetic information, as well as the potential for stigmatization and genetic enhancement.
- Genetic testing and screening should be voluntary, accompanied by proper genetic counseling, and sensitive to cultural practices and religious views.
- The use of genetic testing and screening raises ethical, legal, and social issues, including the possibility of "designer babies" and segregation of humans into classes.
Genomic Education
- Public education and community-based health educational programs can improve awareness of genetic risk and reduce stigma associated with genetic disorders.
- Genetic counseling is crucial in helping people understand and adapt to the genetic, medical, psychological, and familial implications of genetic contributions to disease.
- The importance of genomic education and genetic counseling cannot be overstated, as they help support people in making informed decisions about their health.
CRISPR Gene Editing
- The ethics of CRISPR gene editing, including the possibility of germline or in utero gene correction or modification, raise concerns about creating unfair advantages and segregation of humans into classes.
- Alternative strategies to prevent or cure diseases should be prioritized, and the issue of germline correction requires continuous discussion in the government and the wider community.
