Kuwonjezeka kwa msinkhu wa amayi kungapangitse mwana wanu kuti asakhale ndi chikhalidwe china
Mzimayi amabadwa ndi mazira onse omwe amawapaka nawo moyo wake wonse. Choncho ngati muli ndi zaka 30 pamene mukubala, ndiye kuti dzira lomwe mudakali nalo limakhalanso ndi zaka 30. Ngati muli ndi zaka 45 pamene mukubala, ndiye kuti dzira lomwe mumakhala nalo ndilo zaka 45. Monga mazira msinkhu, amatha kukhala ndi zolakwika zomwe zingabweretse mavuto, monga trisomy 21 (Down syndrome) .
Kodi M'badwo Wa Atate Uwerengera?
Amuna akhoza kupanga umuna mosalekeza m'moyo wawo wonse. Choncho munthu akhoza kukhala ndi zaka 45, koma umuna womwe amaupanga ukhoza kukhala masabata angapo okha. Popeza umuna uli wachinyamata, umalingalira kuti umatetezedwa ku Down syndrome ndi zina zovuta. Ngakhale kuti msinkhu wa abambo suli ndi chiopsezo chosawonongeka kwa chromosome, amuna samachoka. Zaka zapamwamba za makolo zimakhudzanso mwayi wa matenda ena a chibadwa monga achondroplasia ( dwarfism ), Marfan syndrome (matenda omwe amadziwika ndi matalire ndi mavuto a mtima) ndi zina zovuta kwambiri za autosomal.
Kodi Mkwatibwi Wamayi Wapamwamba Ndi Chiyani?
Zaka zakubadwa za amayi amasiye ndilo mankhwala omwe amagwiritsidwa ntchito pofotokoza amayi oyembekezera opitirira zaka 35. Mawuwa sakhala otchuka kwambiri monga chiwerengero chowonjezeka cha amayi achikulire akukhala ndi pakati. Pamene kukhala ndi zaka zapakati pa msinkhu kungapangitse mwayi wanu wokhala ndi mwana yemwe ali ndi matenda a Down syndrome, umakhalanso ndi zotsatira zina za thanzi.
Ndani ayenera kuyesedwa?
Zisanafike chaka cha 2007, American College of Obstetrics ndi Gynecologists (ACOG) ankalimbikitsa kuti amayi onse opitirira zaka makumi asanu ndi awiri (35) aperekedwe kuyesedwa koyezetsa magazi monga amniocentesis ndi chorionic villus . Ali ndi zaka 35, chiopsezo chanu chokhala ndi mwana yemwe ali ndi vuto la chromosomal ndi pafupifupi 1 pa 200 ndipo chiopsezo chokhala ndi pathupi la amniocenteis chinkaganiziridwa kukhala pafupifupi 1 pa 200.
Popeza kuti mitengoyi inkaonedwa kuti ndi yofanana, 35 inasankhidwa ngati zaka zoyambirira zoyenera kuyesa kuyezetsa magazi.
Mu 2007, ACOG inasintha njira yomwe amayi apakati amaperekera kuyesedwa. Zifukwa ziwiri zakhudza kusintha uku ndi ndondomeko. Choyamba, iwo anazindikira kuti chiopsezo chosiya padera kuchokera kwa amniocenteis chinali chochepera kuposa 1 mu 200 (pafupifupi 1 pa 500). Lachiwiri linali chifukwa cha milandu yachipatala yomwe imatsutsana ndi akatswiri odwala matenda opatsirana pogonana pamene amayi achichepere anali ndi ana omwe ali ndi matenda a Down syndrome koma sanaperekedwe kuyesedwa.
Ndikofunika kuzindikira kuti malangizo a ACOG amangotchula omwe ayenera kupereka opaleshoni yopititsa patsogolo. Sitilimbikitsa amayi onse kuti ayesedwe, kuti amayi onse aperekedwe kuyesedwa. Ndi kwa inu kusankha ngati mukufuna kuyesedwa kumene kapena ayi, ndikuyesera kuti mukhale ndi mimba.
Pali zifukwa zambiri zomwe muyenera kuziganizira mukamapanga chisankho choyezetsa magazi. Musanayambe kuyesedwa, ndikofunika kumvetsetsa chiopsezo chanu chokhala ndi mwana wokhala ndi chromosomal, komanso zomwe mungachite ndi zotsatira zosayembekezereka.
