概括
在印度,有针对性的产前查有效地预防了β-thalassemia和状细胞疾病 (SCD) 等血红蛋白病. 这种方法对于弱势群体来说是可行的和可扩展的,
科学领域:
- 遗传学与公共卫生
- 生殖医学
- 血液学
背景情况:
- 印度面临着高血红蛋白病的负担, 包括贝塔血和状细胞病 (SCD).
- 广泛预防的挑战包括耻辱,低意识和不充分的后续行动.
- 桑卡尔普的计划主要针对产前查.
研究的目的:
- 评估针对性的产前查策略的有效性和可行性.
- 评估印度严重血红蛋白病的预防和治疗.
主要方法:
- 这项跨界研究涉及印度五个州36个地区的33,270名孕妇.
- 高性能液体染色学 (HPLC) 查血红蛋白病变.
- 携带者鉴定导致了伴侣测试,分子确认,产前诊断和遗传咨询.
主要成果:
- 在接受查的女性中,有6. 8%为携带者 (2, 268),其中2. 7%为β- thalassemia,3. 5%为SCD.
- 通过对象测试确定了339对有风险的夫妇.
- 产前检测发现65个受影响的胎儿,导致68%的妊娠中断;每787个注册家庭中就有1个受影响的分娩被阻止.
结论:
- 有针对性的产前查是预防血红蛋白病的可行,有效和可扩展的策略.
- 这种方法适用于公共医疗保健系统中的社会经济弱势群体.
- 这一策略有助于预防和治疗印度严重的血红蛋白病.

Preventive Healthcare Services
1.1K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Genome-wide Association Studies-GWAS
14.1K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
