1. Umthwalo Womhlaba Wonke Womdlavuza Wesibeletho kanye Nezinselele Zokuhlola
Umdlavuza wesibeletho usalokhu uyinselele enkulu yezempilo yomphakathi emhlabeni wonke, naphezu kokuthi ungavinjelwa kakhulu ngokuhlolwa okusebenzayo kanye nokungenelela kusenesikhathi. Ngokusho kwe-World Health Organization (WHO), kulinganiselwa ukuthi amacala amasha angu-662,000 kanye nokufa okungu-349,000 kwenzeka emhlabeni wonke ngo-2022, okuwubeka njengomdlavuza wesine ovame kakhulu kanye nembangela yesine ehamba phambili yokufa okuhlobene nomdlavuza phakathi kwabesifazane. Umthwalo wesifo ugxile kakhulu emazweni anengeniso ephansi nephakathi (ama-LMIC), lapho amazinga okusabalala kanye nokufa ephezulu kakhulu kunasezindaweni ezinengeniso ephezulu. Ngokuyinhloko kungenxa yokuntuleka kwezinhlelo zokuhlola ezisezingeni eliphezulu kanye nokutholwa nokwelashwa okuphumelelayo kwezilonda ezingaphambi komdlavuza, okwenziwa ngcono yi:
-Ingqalasizinda yokuhlola engekho noma ebuthaka:Ukuntuleka kwezinsizakalo zokuhlola ezifinyelelekayo neziqinisekisiwe ngekhwalithi.
-Imikhawulo yezinsizakusebenza:Ingqalasizinda yelabhorethri elinganiselwe, izinto ezisebenza ngogesi obandayo, kanye nogesi othembekile.
-Ukuntuleka kwabasebenzi:Ukuntuleka kwabasebenzi abaqeqeshiwe belabhorethri kanye nabasebenzi bezokwelapha.
-Ukubambezeleka nokulahlekelwa ekulandeleni:Isikhathi esisele phakathi kokuqoqwa kwamasampula kanye nokutholakala kwemiphumela, okuholela ekubambezelekeni kokuphathwa kwezokwelapha noma iziguli ezilahlekelwa ukulandelwa [1].
2. I-Etiology kanye ne-Molecular Basis of Cervical Carcinogenesis
Ukutheleleka okuqhubekayo nge-human papillomavirus (HR-HPV) eyingozi kakhulu kuyimbangela ebalulekile yomdlavuza womlomo wesibeletho. Phakathi kwezinhlobo ze-HPV ezingaphezu kuka-200 ezitholakele, okungenani izinhlobo ezingu-12 zihlukaniswe njengezibangela umdlavuza (Iqembu 1) yi-International Agency for Research on Cancer (IARC).
Ezingeni lama-molecule, i-carcinogenesis ebangelwa yi-HPV iqhutshwa kakhulu yi-viral oncoproteins E6 kanye ne-E7. I-E6 ikhuthaza ukuwohloka kweprotheyini yokucindezela isimila i-p53, kuyilapho i-E7 ivimbela iprotheyini ye-retinoblastoma (Rb) ngokusebenzayo, okuholela ekungasebenzi kahle komjikelezo weseli kanye nokuguqulwa okunonya.
3. Amasu Okuhlola Anconywe yi-WHO
I-World Health Organization itusa ukuhlolwa kwe-HPV nucleic acid (NAT) njengendlela yokuhlola eyinhloko ekhethwayo yokuvimbela umdlavuza wesibeletho.
Isibalo sabantu bonke:Ama-NAT asekelwe ku-HPV DNA noma i-mRNA
Abesifazane abaphila ne-HIV:Ama-NAT asekelwe ku-HPV DNA
Izikhawu zokuhlola:
Abesifazane abaneminyaka engu-30-65: Njalo eminyakeni engu-5-10
Abesifazane abaphila ne-HIV: Njalo eminyakeni emi-3-5
Uma kuqhathaniswa nezindlela ezisekelwe ku-cytology, ukuhlolwa kwe-HPV kubonisaukuzwela okuphezulufuthi inikezainani eliphakeme kakhulu lokubikezela elibi, okuvumela izikhawu zokuhlola ezinde futhi ezingabizi kakhulu.
4. Iphrofayili Yomkhiqizo Oqondiwe yi-WHO Yokuhlolwa Kokuhlolwa kwe-HPV
I-WHO isungule uhleloIphrofayili Yomkhiqizo Oqondiwe (i-TPP)zokuhlolwa kokuhlolwa kwe-HPV okuhloswe ukusetshenziswa ezindaweni ezihlukaniswe ngokwezindawo nezinezinsiza ezilinganiselwe.[1]
Izici ezibalulekile zifaka:
-Ukuhambisana namasampula aziqoqele wona
-Ukutholwa kwezinhlobo eziningi ze-HPV eziyingozi kakhulu (≥izinhlobo ezingu-12)
-Ukusebenza ngabasebenzi abangaqeqeshiwe elabhorethri
-Imiphumela iyatholakala ngaphakathi kokuhlangana okukodwa kwezokwelapha
Lezi zindlela zokuhlola zisekela ukuhlolwa kwendawo yokunakekelwa kanye namasu “okuhlola nokwelapha”.
5. Ipulatifomu Yokuthola I-HPV Eyingozi Kakhulu Ezenzakalelayo Ngokugcwele
Uhlelo lwe-AIO800 lwe-Macro & Micro-Test luhlinzekaukuhamba komsebenzi wesampula okuzenzakalelayo ngokupheleleukuhlanganisa ukukhishwa kwe-nucleic acid, ukukhulisa, kanye nokutholwa kwayo ngokuhambisana namasu okuhlola anconywe yi-WHO.
5.1 Ukugeleza Komsebenzi Ozenzakalelayo Wesampula-Ukuphendula
Ipulatifomu ihlanganisa ukukhishwa kwe-nucleic acid, ukukhulisa, kanye nokutholwa ohlelweni olulodwa, oluvaliwe, oludinga ukungenelela okuncane kakhulu komqhubi. Lo mklamo:
-Yehlisa ukuthembela kubasebenzi belabhorethri abakhethekile
-Kunciphisa ukuguquguquka kwenqubo kanye nengozi yokungcoliswa
- Ivumela ukuthunyelwa ezindaweni zokunakekelwa kwempilo ezihlukaniswe ngokwezinga
Ngesikhathi esifanayo, amandla ayo okusebenzisa asekela ukusetshenziswa emalabhorethri amakhulu, okwenza kube lula izinhlelo zokuhlola ezinkulu.
5.2 Ukumbozwa Okubanzi Kohlobo Lwezakhi Zofuzo
Lolu hlelo luthola izinhlobo ze-HPV ezingu-14 ezinobungozi obukhulu, okuhlanganisa zonke izinhlobo ezingu-12 ezibangela umdlavuza ezihlukaniswe yi-IARC (HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, kanye no-59), kanye ne-HPV66 kanye ne-HPV68.
Okubaluleke kakhulu, inikezauhlobo oluthile lwe-genotypingimiphumela, okuvumela ukuhlukaniswa kwezingozi kanye nokuphathwa kwezokwelapha okunembe kakhudlwana.
5.3 Ukuzwela Kokuhlaziya kanye Nemiphumela Yezokwelapha
Njengoba kunomkhawulo wokutholwa kwamakhophi angu-300/mL, uhlelo luyakwazi ukubona ukutheleleka kwe-HPV okuphansi okubangela:
-Ukutholwa kusenesikhathi kwezifo ezihambisana nomtholampilo
-Inani elibikezelayo elibi elithuthukisiwe
-Usekelo lwezikhawu zokuhlola ezinde
5.4 Ukusekelwa Kokuzihlola
Ipulatifomu iyahambisana nazo zombiliamasampula e-cervical swab kanye namasampula omchamo aziqoqele wonaukuhambisana nezincomo ze-WHO ukuze kulungiswe izithiyo ezibalulekile ekuhlolweni, okuhlanganisa:
-Ukufinyelela okulinganiselwe ezikhungweni zezempilo
-Imingcele yezenhlalo namasiko
-Ukungakhululeki kwesiguli ngokuthatha amasampula asekelwe kodokotela
Ukuzihlola ngokwakho kuye kwabonakala kwandisa ukuhlanganyela ezinhlelweni zokuhlola, ikakhulukazi phakathi kwabantu abanganakekelwa kahle.
5.5 Ubuchwepheshe be-Lyophilized Reagent bokugcina indawo
Ukuze kuthuthukiswe ukusetshenziswa kwezilungiselelo ezilinganiselwe zezinsizakusebenza, uhlelo luhlanganisaama-reagent a-lyophilized (omiswe ngokuqandisa)ezizinzile ekushiseni okuzungezile, zinikeza izinzuzo eziningana zokusebenza:
-Ukuzimela kwe-cold-chain: Kuqeda isidingo sokuthutha nokugcina esiqandisini
-Ukuqina okuthuthukisiwe: Kugcina ubuqotho be-reagent ngaphansi kwezimo zemvelo eziguquguqukayo
-Ukuthutha okulula: Kunciphisa izidingo zengqalasizinda kanye nezindleko zokusebenza
-Ukufinyeleleka okuthuthukisiwe: Kusiza ukuthunyelwa ezindaweni ezikude noma ezinganakekelwa kahle
6. Isiphetho
Ushintsho oluvela ekuhlolweni okusekelwe ku-cytology kuya ekuhlolweni kwama-molecule okusekelwe ku-HPV lumelela ushintsho oluyisisekelo ekuvimbeleni umdlavuza wesibeletho. Ngokubheka imbangela eyisisekelo yesifo kunokushintsha kwesimo somzimba, ukuhlolwa kwe-HPV kwenzaukutholwa kusenesikhathi futhi kubucayi kakhulukwabantu abasengozini.
Ngaphezu kwalokho, amapulatifomu okuxilonga ama-molecule azenzakalelayo anikeza indlela ewusizo yokunqoba izithiyo ezikhona ekulethweni kokuhlolwa. Ngokuhlanganisa ukuxilongwa nokwelashwa.ukusebenza okuphezulu kokuhlaziya okulula kokusebenza kanye nokusekelwa kokuzihlola ngokwakho,I-AIO800 inamandla okwandisa ukumbozwa kokuhlolwa, ithuthukise ukutholakala kusenesikhathi, futhi ifake isandla ekunciphiseni umthwalo womhlaba wonke womdlavuza wesibeletho.
