概括
虽然BRCA1/2携带者希望讨论对单一性疾病 (PGT-M) 和产前诊断 (PND) 的植入前遗传测试,但妇科医生缺乏意识和例行咨询. 需要教育努力和明确的指导方针来弥合这一差距.
科学领域:
- 生殖遗传学 生殖遗传学
- 在瘤学瘤学.
- 医学伦理 医学伦理
背景情况:
- BRCA1/2致病变体显著增加遗传性癌症的风险.
- 像PGT-M和PND这样的繁殖选项可供运营商使用.
- 运营商和临床医生对这些选择的知识和态度需要调查.
研究的目的:
- 评估BRCA1/2携带者和妇科医生对PGT-M和PND的认识和态度.
- 确定讨论生殖基因测试选项的障碍和促进因素.
主要方法:
- 采用结构化问卷进行了一项调查.
- 参与者包括89名BRCA1/2携带者和37名妇科医生.
- 该调查评估了与PGT-M和PND相关的认识,态度和道德问题.
主要成果:
- 在信息之前,只有28%的运营商知道PGT-M和PND.
- 在信息后,大多数运营商 (87.6%的PGT-M,85.7%的PND) 支持讨论这些选项.
- 妇科医生对BRCA载体的PGT-M/PND的认识不一致 (45.9%/51.4%),常规讨论不频繁.
- 两组都表达了伦理方面的担忧;临床医生 (86.5%) 要求更明确的指导方针和合作.
结论:
- 在BRCA携带者的生殖偏好与医疗保健专业人员当前的知识和实践之间存在很大的差距.
- 加强医疗保健提供者的教育对于有效的生殖咨询至关重要.
- 制定明确的指导方针和多学科方法对于支持BRCA突变载体的知情决策至关重要.

CRISPR
58.4K
Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced...

Mutagenicity and Carcinogenicity
2.1K
Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...

Genomic Imprinting and Inheritance
37.8K
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...

Human Genetics
1.8K
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
508
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...
