Kafukufuku wa UI adapeza kulumikizana komwe kungachitike pakati pa kufa kwa matenda amtima ndi mitundu ina ya mankhwala ophera tizilombo.Iowa tsopano

Kafukufuku watsopano wochokera ku yunivesite ya Iowa akuwonetsa kuti anthu omwe ali ndi mankhwala ochuluka kwambiri m'matupi awo, kusonyeza kukhudzana ndi mankhwala omwe amagwiritsidwa ntchito kawirikawiri, amatha kufa ndi matenda a mtima.
Zotsatira, zofalitsidwa mu JAMA Internal Medicine, zimasonyeza kuti anthu omwe ali ndi vuto lalikulu la mankhwala ophera tizilombo a pyrethroid amakhala ndi mwayi wocheperapo katatu kufa ndi matenda a mtima kusiyana ndi anthu omwe alibe mankhwala ophera tizilombo a pyrethroid.
Zotsatirazi zimachokera ku kuwunika kwa zitsanzo zoimira dziko lonse la akuluakulu aku US, osati okhawo omwe amagwira ntchito zaulimi, atero a Wei Bao, pulofesa wothandizira wa miliri ku University of Iowa School of Public Health komanso wolemba kafukufukuyu.Izi zikutanthauza kuti zomwe zapezedwa zili ndi tanthauzo pazaumoyo wa anthu wamba.
Anachenjezanso kuti chifukwa ichi ndi kafukufuku wowonetsetsa, sichingadziwe ngati anthu omwe ali pachitsanzo adamwalira chifukwa chokhudzidwa mwachindunji ndi pyrethroids.Zotsatirazi zikusonyeza kuti pali mwayi waukulu wogwirizanitsa, koma kafukufuku wochuluka akufunika kuti abwereze zotsatira ndi kudziwa momwe chilengedwe chimagwirira ntchito, adatero.
Pyrethroids ndi amodzi mwa mankhwala ophera tizilombo omwe amagwiritsidwa ntchito kwambiri pamsika, zomwe zimatengera mankhwala ambiri ophera tizilombo m'nyumba.Amapezeka m'mitundu yambiri yamalonda yamankhwala ophera tizilombo ndipo amagwiritsidwa ntchito kwambiri polimbana ndi tizirombo muzaulimi, pagulu komanso m'nyumba zogona.Ma metabolites a pyrethroids, monga 3-phenoxybenzoic acid, amapezeka mumkodzo wa anthu omwe ali ndi pyrethroids.
Bao ndi gulu lake lofufuza adasanthula deta ya 3-phenoxybenzoic acid mu zitsanzo za mkodzo kuchokera kwa akuluakulu a 2,116 a zaka 20 ndi kupitirira omwe adachita nawo kafukufuku wa National Health and Nutrition Examination Survey pakati pa 1999 ndi 2002. zitsanzo za data zidamwalira pofika 2015 ndipo chifukwa chiyani.
Iwo adapeza kuti pazaka zambiri zotsatiridwa zaka 14, pofika chaka cha 2015, anthu omwe ali ndi 3-phenoxybenzoic acid mu zitsanzo za mkodzo anali 56 peresenti yowonjezera kufa chifukwa cha zifukwa zilizonse kusiyana ndi anthu omwe ali otsika kwambiri.Matenda a mtima, omwe amapha anthu ambiri, ali ndi mwayi wowirikiza katatu.
Ngakhale kuti kafukufuku wa Bao sanadziwe momwe maphunzirowo adawonekera ku pyrethroids, adanena kuti kafukufuku wam'mbuyomu adawonetsa kuti kuwonetseredwa kwa pyrethroid kumachitika kudzera m'zakudya, popeza anthu omwe amadya zipatso ndi ndiwo zamasamba zopopera ndi pyrethroids amamwa mankhwalawo.Kugwiritsiridwa ntchito kwa pyrethroids polimbana ndi tizilombo m'minda ndi m'nyumba ndizofunikanso kuwononga tizilombo.Ma pyrethroids amapezekanso m'fumbi lanyumba momwe mankhwala ophera tizilombowa amagwiritsidwa ntchito.
Bao adanenanso kuti gawo la msika wamankhwala a pyrethroidchawonjezeka kuyambira nthawi yophunzira ya 1999-2002, zomwe zimapangitsa kuti kufa kwa mtima chifukwa cha kukhudzidwa kwawo kwawonjezeka.Komabe, kafukufuku wina akufunika kuti awone ngati lingaliro ili ndilolondola, adatero Bao.
Pepalalo, "Kugwirizana kwa kukhudzana ndi mankhwala ophera tizilombo komanso kuopsa kwa kufa kwa zifukwa zonse ndi zifukwa zenizeni pakati pa akuluakulu a US," inalembedwa ndi Buyun Liu ndi Hans-Joachim Lemler wa University of Illinois School of Public Health., pamodzi ndi Derek Simonson, wophunzira womaliza maphunziro ku yunivesite ya Illinois mu toxicology yaumunthu.Lofalitsidwa mu Disembala 30, 2019 ya JAMA Internal Medicine.
