\nStudiul cercet\u0103torilor de la Icahn School of Medicine din Mount Sinai a analizat probe de s\u00e2nge din cordonul ombilical colectate \u00eentre 2003 \u015fi 2006 de la 120 de copii. Cercet\u0103torii au folosit o metod\u0103 ne\u0163intit\u0103, care scaneaz\u0103 simultan sute de substan\u0163e chimice. Metodele tradi\u0163ionale testau doar o list\u0103 scurt\u0103 \u015fi predefinit\u0103.<\/p>\n
\nPFAS sunt substan\u0163e chimice artificiale folosite \u00een vase antiaderente, \u0163es\u0103turi rezistente la pete, ambalaje alimentare \u015fi spume de stingere a incendiilor. Sunt numite \u201esubstan\u0163e chimice ve\u015fnice” deoarece persist\u0103 \u00een mediu \u015fi \u00een corpul uman. Efectele lor asupra s\u0103n\u0103t\u0103\u0163ii umane sunt pu\u0163in cunoscute. Tocmai de aceea, \u00een\u0163elegerea expunerii cumulative \u00een uter este crucial\u0103.<\/p>\n
\nCercet\u0103torii au confirmat sau identificat prezumtiv 42 de compu\u015fi PFAS \u00een s\u00e2ngele din cordonul ombilical. Multe dintre acestea nu sunt testate prin metodele tradi\u0163ionale, iar efectele lor asupra s\u0103n\u0103t\u0103\u0163ii sunt necunoscute. Expunerea prenatal\u0103 la substan\u0163e chimice PFAS a fost asociat\u0103 \u00een studiile anterioare cu greutate sc\u0103zut\u0103 la na\u015ftere, na\u015ftere prematur\u0103 \u015fi modific\u0103ri ale r\u0103spunsului imunitar la vaccinuri.<\/p>\n
\n\u201eC\u00e2nd privim mai cuprinz\u0103tor, vedem c\u0103 bebelu\u015fii sunt expu\u015fi la mult mai multe substan\u0163e chimice PFAS \u00eenainte de na\u015ftere dec\u00e2t ne-am dat seama”, a declarat dr. Shelley H. Liu, autorul principal al studiului.<\/p>\n
\nExpunerea la PFAS nu este m\u0103surat\u0103 \u00een prezent \u00een \u00eengrijirea clinic\u0103 de rutin\u0103. Noua metod\u0103 ar putea ajuta medicii s\u0103 identifice persoanele cu expunere mai mare \u015fi s\u0103 monitorizeze popula\u0163iile la risc. Colegiul American de Obstetricieni \u015fi Ginecologi a identificat reducerea expunerii la PFAS ca o \u201ezon\u0103 critic\u0103 de interven\u0163ie”.<\/p>\n
\n\u201eObiectivul nostru este s\u0103 avans\u0103m c\u0103tre identificarea \u015fi prevenirea timpurie, \u00een special \u00een perioadele sensibile, cum ar fi sarcina”, a spus dr. Liu.<\/p>\n
\nEchipa de cercetare inten\u0163ioneaz\u0103 s\u0103 studieze dac\u0103 expunerea cumulativ\u0103 mai mare la substan\u0163e chimice PFAS \u00een primii ani de via\u0163\u0103 duce la efecte negative pe termen lung asupra s\u0103n\u0103t\u0103\u0163ii.<\/p>\n
