Raporo y’ishyirahamwe mpuzamahanga rya Alzheimer (AAIC) 2021: Kunoza ubwiza bw’ikirere bishobora kugabanya ibyago byo guta umutwe

Ihuriro mpuzamahanga rya Alzheimer (AAIC-2021) ryafunguwe ku ya 26 Nyakanga 2021.AAIC ni imwe mu nama mpuzamahanga nini kandi zikomeye ku isi yibanda ku bushakashatsi bwa siyansi ku bijyanye no guta umutwe.AAIC yabereye kumurongo no kurubuga i Denver, muri Amerika uyu mwaka.Indwara ya Alzheimer (AD) niyo ndwara ikunze kwibasira abasaza kandi yabaye ikibazo gikomeye ku buzima bwabo ndetse n’umutwaro ukomeye mu bukungu kuri sosiyete.Kugabanya AD ntibisaba gusa kuvura neza no guhanga udushya, ahubwo bisaba ibikoresho byizewe byo gusuzuma hakiri kare n'ingamba zo gukumira zigera kubantu benshi.

Kunoza ikirere cyiza bigabanya cyane ibyago byo guta umutwe

Ubushakashatsi bwinshi bwibanze bwerekanye ko guta umutwe bifitanye isano na proteyine ya amyloide mu bwonko bitewe n’igihe kirekire cyo guhumanya ikirere.Icyakora, nta bushakashatsi bwemeje niba gukuraho ihumana ry’ikirere bigabanya ibyago byo guta umutwe na AD.

Muri AAIC 2021, ubushakashatsi bwakorewe muri Amerika no mu Bufaransa bwerekanye ku nshuro ya mbere isano iri hagati yo kugabanya ihumana ry’ikirere no kugabanya ibyago byo guta umutwe.Ubushakashatsi bwakozwe nitsinda rya USC bwerekanyeko abagore bakuze baba mu turere aho PM2.5 (igipimo cyerekana umwanda uhumanye neza) bari munsi ya 10% ugereranije n’urwego rwashyizweho n’ikigo cy’Amerika gishinzwe kurengera ibidukikije (EPA) bafite ibyago 14% byo guta umutwe.kuva 2008 kugeza 2018.Abagore bakuze baba mu turere aho dioxyde ya azote (NO2, ihumanya ituruka ku muhanda) yari munsi ya 10% ugereranije n’ibisanzwe bari bafite ibyago 26% byo guta umutwe!

Ubushakashatsi bwerekanye ko izo nyungu zitagendeye ku myaka no ku rwego rw'uburezi abitabiriye amahugurwa ndetse niba bafite n'indwara z'umutima.

Ibisubizo nkibi byabonetse mubushakashatsi bwakorewe mubufaransa, bwerekanye kokugabanya ibipimo bya PM2.5 na 1 µg / m³ubwinshi bwikirere bwajyanye no kugabanya 15% ibyago byo guta umutwe no kugabanuka kwa 17% ibyago bya AD.

"Kuva kera, tuzi ko ihumana ry’ikirere ryangiza ubwonko bwacu ndetse n'ubuzima muri rusange."Dr Claire Sexton wo mu muryango wa Alzheimer yagize ati: "Birashimishije kubona ubu dusanze amakuru yerekana ko kuzamura ireme ry’ikirere bigabanya ibyago byo guta umutwe.Aya makuru yerekana akamaro ko kugabanya ihumana ry’ikirere."
