Malinga ndi kafukufuku wofalitsidwa mu Annals of Internal Medicine, fyuluta yamadzi yogulitsa mwina ndiyo inayambitsa matenda a odwala anayi omwe adachitidwa opaleshoni ya mtima ku Brigham and Women's Hospital, ndipo atatu mwa iwo anamwalira.
Kufalikira kwa matenda a M. abscessus okhudzana ndi chisamaliro chaumoyo, komwe kumafotokozedwa ngati "matenda osowa koma ofotokozedwa bwino a nosocomial", komwe kale kunkatchedwa "machitidwe amadzi oipitsidwa" monga makina oundana ndi madzi, makina onyowetsa chinyezi, mapaipi a m'chipatala, kwa odwala omwe akuchitidwa opaleshoni yodutsa, zida zotenthetsera ndi zoziziritsira, mankhwala ndi mankhwala ophera tizilombo toyambitsa matenda.
Mu June 2018, Brigham ndi Women's Hospital control idanena kuti Mycobacterium abscessus subsp.abscessus yalowa m'thupi mwa odwala angapo omwe akuchitidwa opaleshoni ya mtima. Matenda a m'mimba, omwe angayambitse matenda m'magazi, m'mapapo, pakhungu, ndi m'minofu yofewa, makamaka mwa anthu omwe ali ndi chitetezo chamthupi chofooka.
Ofufuzawo adachita kafukufuku wofotokozera bwino magulu a matenda. Anayang'ana kufanana pakati pa odwala, monga zida zotenthetsera ndi zoziziritsira zomwe zimagwiritsidwa ntchito, kapena zipinda zochitira opaleshoni, pansi pa zipatala ndi zipinda, komanso mwayi wopeza zida zina. Ofufuzawo adatenganso zitsanzo za madzi kuchokera mchipinda chilichonse chomwe odwalawo amakhala, komanso kuchokera ku akasupe awiri akumwa ndi makina oundana omwe ali pansi pa opaleshoni ya mtima.
Odwala onse anayi "adalandira chithandizo chamankhwala chotsutsana ndi mabakiteriya ambiri," koma atatu mwa iwo anamwalira, Klompas ndi anzake adalemba.
Ofufuzawo adapeza kuti odwala onse anali pamlingo wofanana kuchipatala koma analibe zinthu zina zofanana. Pofufuza opanga ayezi ndi operekera madzi, adawona kukula kwakukulu kwa mabakiteriya a mycobacteria pamagulu a cluster, koma osati kwina kulikonse.
Kenako, pogwiritsa ntchito njira yonse yowerengera majini, adapeza zinthu zofanana ndi majini m'makasupe akumwa ndi makina oundana pansi pa chipatala komwe odwala omwe ali ndi kachilomboka anali. Madzi opita ku magalimoto amadutsa mu chotsukira madzi chosefedwa ndi kaboni chomwe chimayatsidwa ndi kuwala kwa ultraviolet, komwe ofufuza adapeza kuti kumachepetsa kuchuluka kwa chlorine m'madzi, zomwe zitha kupangitsa kuti mabakiteriya a mycobacteria alowe m'magalimoto.
Odwala omwe ali pachiwopsezo chachikulu atasintha kugwiritsa ntchito madzi osaphikidwa, kuwonjezera kukonza kwa makina operekera madzi, kuzimitsa makina oyeretsera, panalibe milandu ina.
"Kuyika zida zapaipi zamalonda kuti ziwongolere kukoma ndikuchepetsa fungo la madzi akumwa a odwala kungakhale ndi zotsatira zosayembekezereka zolimbikitsa kufalikira kwa tizilombo toyambitsa matenda ndi kuberekana," ofufuzawo akulemba. Madzi (monga kuchulukitsa kubwezeretsanso madzi kuti achepetse kugwiritsa ntchito kutentha) mosazindikira kungawonjezere chiopsezo cha matenda opatsirana mwa kuchepetsa chlorine ndikulimbikitsa kukula kwa tizilombo toyambitsa matenda."
Klompas ndi anzake adatsimikiza kuti kafukufuku wawo "akuwonetsa chiopsezo cha zotsatira zosayembekezereka zokhudzana ndi machitidwe omwe adapangidwa kuti apititse patsogolo kugwiritsa ntchito madzi m'zipatala, chizolowezi cha kuipitsidwa kwa tizilombo toyambitsa matenda a ayezi ndi akasupe akumwa, komanso chiopsezo chomwe izi zimabweretsa kwa odwala." kuthandizira mapulogalamu oyang'anira madzi kuti ayang'anire ndikupewa matenda a mycobacterial a nosocomial.
"Mokulira, zomwe takumana nazo zikutsimikizira zoopsa zomwe zingachitike pogwiritsa ntchito madzi apampopi ndi ayezi posamalira odwala omwe ali pachiwopsezo, komanso phindu lomwe lingachitike pochita njira zatsopano zochepetsera kufalikira kwa odwala omwe ali pachiwopsezo ndi madzi apampopi ndi ayezi panthawi ya chisamaliro chanthawi zonse," adalemba.
