Ubushakashatsi bwa UI bwerekanye isano iri hagati yimpfu zindwara zifata umutima nubwoko bumwe na bumwe bwica udukoko.Iowa ubu

Ubushakashatsi bushya bwakozwe na kaminuza ya Iowa bwerekana ko abantu bafite imiti myinshi y’imiti runaka mu mibiri yabo, byerekana ko bahura n’imiti yica udukoko ikoreshwa cyane, bashobora guhitanwa n’indwara zifata umutima.
Ibisubizo byatangajwe muri JAMA Medicine Internal Medicine, byerekana ko abantu bafite imiti myinshi yica udukoko twangiza pyrethroide badakunda guhitanwa n’indwara zifata umutima ndetse n’abantu badafite imiti yica udukoko twa pyrethide.
Wei Bao, umwungirije wungirije wa epidemiologiya mu ishuri ry’ubuzima rusange rya kaminuza ya Iowa akaba n'umwanditsi w’ubwo bushakashatsi, yatangaje ko ibisubizo byaturutse ku isesengura ry’icyitegererezo cy’igihugu cy’abantu bakuze bo muri Amerika, atari abakora mu buhinzi gusa.Ibi bivuze ko ibyagaragaye bifite ingaruka ku buzima rusange bwabaturage muri rusange.
Yibukije kandi ko kubera ko ubu ari ubushakashatsi bwo kureba, budashobora kumenya niba abantu bari mu cyitegererezo bapfuye bazize kwandura pyrethroide.Yavuze ko ibisubizo byerekana ko hashobora kubaho isano, ariko hakenewe ubushakashatsi bwinshi kugira ngo bigaragaze ibisubizo kandi hamenyekane uburyo bw’ibinyabuzima.
Pyrethroide iri mu miti yica udukoko dukunze kugabana ku isoko, ikaba ifite umubare munini w’udukoko twica udukoko two mu rugo.Baboneka mubirango byinshi byubucuruzi byica udukoko kandi bikoreshwa cyane mukurwanya udukoko mubuhinzi, rusange ndetse n’imiturire.Metabolite ya pyrethroide, nka aside 3-fenoxybenzoic, irashobora kuboneka mu nkari zabantu bahuye na pyrethroide.
Bao n'itsinda rye ry’ubushakashatsi bakoze isesengura ku mibare ya aside-fenoxybenzoic ya 3 mu ngero z’inkari ziva ku bantu bakuze 2,116 bafite imyaka 20 n’abayirengeje bitabiriye ubushakashatsi bw’ibizamini by’ubuzima n’imirire hagati y’19999 na 2002. Bakusanyije amakuru y’impfu kugira ngo bamenye umubare w'abantu bakuru muri bo sample sample yari yarapfuye muri 2015 n'impamvu.
Basanze mu gihe cyo gukurikiranwa mu gihe cy’imyaka 14, kugeza mu 2015, abantu bafite urugero rwinshi rwa aside-fenoxybenzoic ya 3 mu ngero z’inkari bari 56% bapfa bazize impanuka iyo ari yo yose kurusha abantu bafite urwego rwo hasi rw’ibibazo.Indwara z'umutima-damura, kugeza ubu nizo zitera urupfu, zikubye inshuro eshatu.
N'ubwo ubushakashatsi bwa Bao butagaragaje uburyo amasomo yahuye na pyrethroide, yavuze ko ubushakashatsi bwibanze bwerekanye ko pyrethroide nyinshi ibaho binyuze mu biryo, kuko abantu barya imbuto n'imboga batewe na pyrethroide binjiza imiti.Gukoresha pyrethroide mu kurwanya udukoko mu busitani no mu ngo nabyo ni isoko yingenzi yo kwanduza.Pyrethroide nayo igaragara mu mukungugu wo murugo aho iyi miti yica udukoko ikoreshwa.
Bao yavuze ko umugabane w isoko waudukoko twangiza pyrethroidyariyongereye kuva igihe cyo kwiga 1999-2002, bituma bishoboka ko impfu z'umutima-damura zijyanye no guhura kwabo nazo ziyongereye.Bao yavuze ko ariko hakenewe ubundi bushakashatsi kugira ngo hamenyekane niba iyi hypothesis ari yo.
Uru rupapuro, “Ishyirahamwe ry’udukoko twangiza udukoko twangiza pyrethroide hamwe n’impanuka ziterwa n’impamvu zose n’impamvu zitera abantu bakuze bo muri Amerika,” byanditswe na Buyun Liu na Hans-Joachim Lemler bo mu ishuri ry’ubuzima rusange rya kaminuza ya Illinois., hamwe na Derek Simonson, umunyeshuri urangije muri kaminuza ya Illinois muri toxicology ya muntu.Byasohotse mu nomero ya 30 Ukuboza 2019 yubuvuzi bwimbere muri JAMA.
