Multiple sclerosis: Mwina si vitamini D yochokera kudzuwa yomwe imathandiza anthu omwe ali ndi multiple sclerosis, koma kuwala kwa UVB.
Ndiko kulondola ... kuwala komweko komwe kumayambitsa khansa yapakhungu.
Helen Tremlett, PhD, pulofesa wa neuroepidemiology ndi multiple sclerosis ku Djavad Mowafaghian Center for Brain Health, adaphunzira kutentha kwa dzuwa pa miyoyo ya odwala multiple sclerosis pogwiritsa ntchito chidziwitso chapamwamba. ku NASA.
Kuchokera ku gulu la Nurses 'Health Study, anthu 3 omwe ali ndi multiple sclerosis (MS) adasinthidwa kukhala geocoded.
Zambirizi zidafaniziridwa ndikuwunikidwa ndi data ya NASA UVB.
Tremlett ndi gulu lake adapita ku Boston makamaka kwa gulu la Nurses' Health Study.
"Kusanthula mafunso amtunduwu ndi chida chachikulu komanso champhamvu. Iwo ankatsatira akazi amene anali anamwino ku United States. Patapita nthawi, ena anayamba kudwala matenda monga MS,” Tremlett anauza Healthline.
Omwe amakhala m'malo okhala ndi UVB yayikulu anali ndi chiopsezo chochepa cha 45% cha MS. Kutenthedwa ndi dzuwa lachilimwe kwambiri m'madera okwera a UVB kunkagwirizananso ndi kuchepetsa chiopsezo.
"Anthu sankasowa khungu lochuluka, kuti angokhala padzuwa," adatero Tremlett.
Thupi limapanga vitamini D likakhala padzuwa. Komabe, kafukufukuyu akuwonetsa kuti pali zambiri kuposa vitamini D zomwe zimasewera pano.
"Sitikudziwa momwe zimagwirira ntchito," adatero Tremlett. "Mwachitsanzo, zikhoza kukhala kuti dzuwa limagunda retina kumbuyo kwa diso, zomwe zimakhudza kuchuluka kwa melatonin yomwe imapangidwa, yomwe imakhudza circadian rhythm. Izi zitha kukhudza kugona komanso kuwongolera chitetezo chamthupi, "atero Tremlett.
Zamkatimu
Phunziro lina ladzuwa
Pulojekiti ina yofufuza, Sunlight Study, idawunikiranso kukhudzana ndi dzuwa komanso ubale wake ndi MS.
Kuphatikiza apo, kafukufukuyu adasanthula kuchuluka kwa vitamini D ndikugawa milandu ndi zowongolera kukhala anthu aku Caucasus ndi anthu amtundu waku Africa ndi Puerto Rico.
Milandu ndi macheke adatengedwa ndi mamembala a Kaiser Permanente Southern California.
Kafukufuku wambiri wasonyeza ubale pakati pa vitamini D ndi MS. Koma kafukufukuyu akukayikira kuti vitamini D ndi yomwe imayambitsa MS komanso ntchito yake pakulimbikitsa thanzi, makamaka kwa anthu amtundu waku Africa ndi Puerto Rico.
Vitamini D wokwera kwambiri amalumikizidwa ndi chiopsezo chochepa cha multiple sclerosis mwa azungu okha, osati mwa anthu a ku Africa ndi ku Spain. Panalibe kugwirizana kwa timagulu tating'ono.
Zatsimikiziridwanso kuti kuwonetseredwa kwa moyo wonse kumawoneka kuchepetsa chiopsezo cha MS, mosasamala kanthu za fuko kapena fuko.
“Anthu amene amakhala panja nthawi zambiri amachita zinthu zolimbitsa thupi monga kuyenda, kukwera mapiri, kukwera njinga, kuthamanga, kapena kulima dimba. Kotero zikhoza kukhala kuphatikiza masewera olimbitsa thupi akunja omwe amatetezadi anthu ku MS, "adatero Dr. Annette Langer-Gould, wothandizira ku Kaiser Permanente Southern California ku Pasadena, membala wa American Academy of Neurology.
Miyezo ya vitamini D ndi njira yosavuta yoyezera izi molakwika ku Caucasus, koma osati mwa anthu a ku Spain kapena ku Africa, omwe ma vitamini D samakwera kwambiri ngakhale atakhala ndi dzuwa lomwelo.
"Cholinga changa ndikupeza kuwala kwa dzuwa kuchokera kuzinthu zachilengedwe, kuvala zoteteza ku dzuwa pofuna kupewa khansa yapakhungu, ndikuyesera kuthera mphindi 30 patsiku ndikuchita zinthu zakunja monga kuyenda kapena kulima," Langer-Gould anauza Healthline.
"Zili ndi chochita ndi chitetezo cha mthupi, maselo olamulira akuwonjezera ultraviolet," adatero Nick LaRocca, PhD, wachiwiri kwa pulezidenti wopereka chithandizo chamankhwala ndi kafukufuku wa ndondomeko ku National Multiple Sclerosis Society.
"Pali chidwi chowonjezereka chakuti kuwala kwa UV kumatenga gawo pachiwopsezo cha MS, osadalira gawo la vitamini D," adauza Healthline.
Maphunzirowa adayang'ana komwe anthu adakulira komanso kulumikizana ndi MS.
Maphunziro akuyamba ku Australia
Chaka chatha, Prue Hart, Ph.D., waku Western Australia, adagwiritsa ntchito bwino ma radiation a UV pa multiple sclerosis odwala omwe anali ndi vuto koma palibe matenda ena.
Pambuyo pa zotsatira zabwino, Hart adapanga kuyesa kwa PhoCIS kuti apitirize kuphunzira zotsatira za kuwala kwa UV (phototherapy) pa odwala a MS omwe ali ndi matenda a isolated syndrome (CIS).
Kafukufukuyu akulemba anthu.
"Ngati udindo wa kuwala kwa dzuwa ndi wovuta kwambiri kuposa momwe timayembekezera, tiyenera kudziwa," adatero LaRocca, ndikuwonjezera kuti "pa chilichonse chokhudzana ndi multiple sclerosis, ndizovuta."
Zolemba mkonzi: Caroline Craven ndi katswiri wa odwala a MS. Blog yake yopambana mphoto ndi GirlwithMS.com, ndipo akupezeka pa Twitter.
