Ukuba unesifo seswekile, mhlawumbi ukhathazekile ngempilo yamehlo akho. Ugqirha wakho usenokuba ukuxelele ukuba isifo seswekile sichaphazela amehlo akho, imeko ebizwa ngokuba yiDiabetic Macular Edema (DME). Ngoko ke, xa kufikwa ekunyangeni esi sifo, ngaba wakha weva 'ngesilingo seklinikhi'? Ukuva eli gama kunokoyikisa kancinci. Usenokuba ucinga, "Ngaba ndiyavavanywa?" Kodwa asiyonto yokoyika. Namhlanje, masithethe ngento eyiyo ngokwenene, zeziphi izibonelelo ezinokukuzisela zona, kunye nokuba ikulungele na.
Ngamafutshane, yintoni uvavanyo lweklinikhi?
Cinga ngalo naliphi na iyeza olithengayo kwikhemesti. Ukususela kumayeza omkhuhlane nokukhwehlela ukuya kumayeza esifo sakho seswekile kunye noxinzelelo lwegazi, yonke into ivavanywa ngokuqatha ngaphambi kokuba ifikelele ezandleni zakho. Olo vavanyo yinto esiyibiza ngokuba yi-'Clinical Trial'.
Ngamafutshane, le yinkqubo yokuvavanya iyeza elitsha ngaphambi kokuba ulinike abantu ukuze babone ukuba liyasebenza na (liyasebenza) kwaye likhuselekile ukulisebenzisa (likhuselekile) . Oku kwenziwa ngendlela ecwangcisiweyo kakhulu, phantsi kweliso elibukhali loogqirha nabaphandi. Ngenxa yoku, iqela lezigulana ezizinikelayo ukuba zinikwe olu nyango lutsha kwaye imeko yazo ijongwa ngokusondeleyo. Ngoko ke oku akufani nokuba "yi-guinea pig" konke konke. Oku kwenziwa phantsi kwemithetho esemthethweni neyokuziphatha, kwaye ukhuseleko lwezigulana luyinto ephambili.
Kuphela emva kokuphumelela uvavanyo olunjalo, amaziko afana neNational Medicines Regulatory Authority (NMRA) yaseSri Lanka anika imvume yokuba eli yeza lisetyenziswe kweli lizwe.
Zithini iingenelo zovavanyo lweklinikhi kumntu one-DME?
Usenokuba ucinga, "Kulungile, yiyo loo nto, kodwa kutheni ndibandakanyeka koku? Iyintoni inzuzo kum?" Enyanisweni kukho iingenelo ezininzi. Makhe sizijonge.
| Inzuzo | Ithetha ukuba... |
|---|---|
| Ukufikelela kunyango oluphambili | Uza kuba nethuba lokuzama unyango olutsha olungekafikeleli kwimarike eqhelekileyo. Lusenokuba liyeza elinganikwanga ngugqirha wakho ngokuqhelekileyo. |
| Amandla okufumana iziphumo ezingcono | Ngamanye amaxesha olu nyango lutsha lunokuba lusebenza ngakumbi kunonyango olukhoyo, oko kuthetha ukuba umbono wakho unokuphucula okanye imeko yakho inokulawulwa ngokukhawuleza. |
| Ulawulo olusondeleyo kakhulu lwezonyango | Uza kufumana ingqwalasela engaphezulu kunye nolawulo olungaphezulu kunokuba ubuya kufumana rhoqo xa usiya ekliniki. Uza kuvavanywa rhoqo, kwaye oogqirha baza kujonga imeko yakho rhoqo. |
| Ukunceda ikamva | Ngokubandakanyeka, unegalelo ekwandiseni ukuqonda kwesayensi nge-DME kwaye unceda ekuboneleleni ngonyango olungcono kwabanye abanale sifo kwixesha elizayo. |
Zithini iinjongo zabaphandi?
Kukho iinjongo eziphambili ezininzi zophando lwangoku kwi-DME.
- Ukunciphisa inani lokuya ekliniki: Khawucinge ukuba bekuya kuba lula kangakanani ukuba ubunganyanzelekanga ukuba uye esibhedlele rhoqo ukuze ufumane inaliti yamehlo. Abaphandi bazama ukufumana amayeza ahlala ixesha elide.
- Iipilisi endaweni yenaliti: Abanye abantu bakufumanisa kunzima ukufaka inaliti elisweni. Kuthekani ukuba esi sifo singalawulwa ngepilisi ethathwa imihla ngemihla endaweni yoko? Le yenye indawo enkulu yophando.
- Ukwandisa ukusebenza kakuhle konyango: Enye injongo kukufumana amayeza angcono nasebenza ngakumbi kunamayeza akhoyo.
Lusebenza njani uvavanyo lweklinikhi?
Ezi zilingo zinokwahlulwa zibe ziintlobo ezimbini eziphambili. Kodwa masithethe ngohlobo oluqhelekileyo. Lubizwa ngokuba yi-'Interventional Trial'.
Oku kubandakanya abaphandi abanika unyango (njengonyango okanye inaliti) kunye nokufunda ngemiphumo yalo. Oku kungenziwa ngeendlela ezahlukeneyo.
Kodwa amaxesha amaninzi, kusetyenziswa indlela ebizwa ngokuba yi-'Randomized Controlled Trial' . Nangona eli gama liyinkimbinkimbi kancinci, ingcamango ilula.
Khawuthelekelele ukuba abantu abali-100 bazithandela olu vavanyo.
1. Ukwahlulahlula ngokwamaqela:Aba bantu bali-100 bahlulwe ngokungacwangciswanga baba ngamaqela amabini abantu abangama-50 ngalinye, kungekho kukhetha.
2. Ukubonelela ngonyango:
- Iqela lokuqala (abantu abangama-50): liza kunikwa unyango olusandula ukuvavanywa.
- Iqela lesibini (elinye elingama-50): liza kuqhubeka nokufumana unyango olusemgangathweni nolungcono olusetyenziswayo ngoku kwi-DME. Eli qela libizwa ngokuba yi-'Control Group'.
3. Uthelekiso: Emva kwexesha elithile, iziphumo zamaqela omabini ziyathelekiswa. Lungcono kangakanani unyango olutsha kunonyango oludala? Ngaba luneziphumo ebezingalindelekanga ezimbalwa? Ngaba lukhuselekile? Yonke into inokulinganiswa ngokuchanekileyo ngale nto.
Ngaphandle kokuthelekisa neqela lolawulo ngale ndlela, akunakwenzeka ukungqina ngokwesayensi ukuba iyeza elitsha lisebenza kangakanani ngokwenene. Yiyo loo nto le ndlela ibaluleke kangaka.
Ndingabandakanyeka njani kwinto efana nale?
Lo ngumbuzo obaluleke kakhulu. Ukuba unomdla koku, inyathelo lokuqala nelibalulekileyo ekufuneka ulithathe kukuthetha nogqirha wakho wamehlo okanye ugqirha weswekile onyangayo.
- Ugqirha wakho uyazi kakuhle imeko yakho yempilo kunye nembali yakho yempilo, ngoko ke angakunika icebiso elifanelekileyo lokuba kufanelekile na ukuba uthathe inxaxheba kolu vavanyo.
- Izifundo ezinjalo zenziwa rhoqo kwizibhedlele ezinkulu zikarhulumente eSri Lanka, ingakumbi ezo zinxulumene neengcali zonyango. Ugqirha wakho uya kukwazi ukufumanisa ukuba kukho uvavanyo oluqhutywayo olufanelekileyo kuwe aze akuthumelele lona.
- Ungaze wenze izigqibo ezinje wedwa ngaphandle kokubonisana nogqirha wakho.
Ngaphambi kokuba uthathe inxaxheba, iqela elijongene nophando liza kukuchazela yonke into (oko kuza kwenziwa, iingozi ezinokubakho, iingenelo). Imvume yakho ebhaliweyo iya kufumaneka kuphela emva kokuba ubuze nayiphi na imibuzo kwaye wanelisekile ngokupheleleyo. Kwakhona, ukuba uziva ungakhululekanga nangaliphi na ixesha ngexesha lophando, unelungelo elipheleleyo lokurhoxa kulo.
Umyalezo Wokuya Ekhaya
- Uvavanyo lweklinikhi luphononongo olusemthethweni oluqhutywa ukuqinisekisa ukhuseleko nokusebenza kakuhle kweyeza elitsha ngaphambi kokuba linikwe abantu.
- Ngokuthatha inxaxheba kuvavanyo olufana nolu, nina, abane-DME, ninethuba lokufumana unyango lwamva nje olungafumanekiyo okwangoku kwaye nifumane ulwalathiso olungcono lwezonyango.
- Oku kuluncedo kakhulu kuwe nakwabanye abanokuba nesi sifo kwixesha elizayo.
- Ukuba unomdla koku, okokuqala, thetha nogqirha wakho uze ucele icebiso lakhe.
