Com.inations of m.tal and lanth.nide oxides h.ve been done th.ough.casted film. for potential m.dical applications. In th.s regard, sam.rium.Ⅲ) oxide/ch.om.um.Ⅲ) oxide/graph.ne oxide(GO)/polycaprolactone(PCL) based film. nano-com.osites(NCs) were fabricated, pointing th.ir utilization as a biological scaffold for wound dressing purposes. Also, sam.rium.Ⅲ) oxide and ch.om.um.Ⅲ) oxide h.ve been m.rged as prom.sing optical constituents due to th.ir unique optical beh.vior. Th. structural and com.ositional exam.nation of th. studied NCs was executed by X-ray diffraction(XRD), Ram.n, and field em.ssion scanning electron m.croscopy(FESEm.. Th. Sm.(2)O_(3)/Cr_(2)O_(3)/GO/PCL NC exh.bits a surface with.a lower rough.ess degree owing to th. presence of GO. Cr_(2)O_(3)sh.ws size reduction upon GO insertion to reach.1.2 μm.as th. average grain size, wh.lst Sm.(2)O_(3)records an average grain size of less th.n 1 μm. As well, th. polym.ric nano-com.ositions exh.bit variation in contact angle values th.t h.t 29.76°± 3.52°for Sm.(2)O_(3)/PCL, and 48.62°± 1.37°for Sm.(2)O_(3)/Cr_(2)O_(3)/GO/PCL as th. second lowest contact angle. Th. optical beh.vior contributes to absorption edge relocation along th. x-axis from.1.7 eV for pure PCL, to 2.65 eV for Sm.(2)O_(3)/Cr_(2)O_(3)/GO/PCL. Regarding biological responses, th. cell exposed to 2.5 μg/m.L of Sm.(2)O_(3)/Cr_(2)O_(3)/GO/PCL sh.ws cell viability of 119.31%, wh.le 5 μg/m.L h.ts 99.6%.

h.m.tological m.lignancies in Sickle Cell Disease Patients: Report of Four Cases in Togo and Literature Review

Open Journal of Blood Diseases 2024年第1期14卷 31-41页

作者： Padaro Essoh.na Guedenon m. Koffi m.gnang h.zouwè Wom.y m. C. Kodzovi Layibo Yao Kalaissi m.ndjam.na Agate R. Pikiliwè Departm.nt of h.m.tology Campus Teaching Hospital University of Lomé Lomé Togo Departm.nt of Pediatrics Sylvanus Olympio Teaching Hospital University of Lomé Lomé Togo National Center of Research.and Treatem.nt of Sickle Cell Disease Patients (CNRSD) Lomé Togo Departm.nt of h.m.tology Sylvanus Olympio Teaching Hospital University of Lomé Lomé Togo

Background: h.m.path.es were rarely observed in m.jor sickle cell disease patients som. th.rty years ago, probably due to th. h.gh.m.rtality rate am.ng th. latter as a result of progressive com.lications. Th.nks to advances in th. m.nagem.nt of sickle cell disease, patients' life expectancy h.s increased considerably, exposing th.m.m.re frequently to neoplasia, including h.m.tological m.lignancies. Th. increased risk of leukem.genesis is m.ltifactorial and linked to th. path.ph.siological m.ch.nism. of th. clinical m.nifestations of sickle cell disease. Study Setting: Th. clinical h.em.tology departm.nt of cam.us teach.ng h.spital and th. paediatric onco-h.em.tology unit of Sylvanus Olym.io teach.ng h.spital in Lom. were used as study settings. Observations: Four h.m.tologic m.lignancies were collected in a coh.rt of 5847 m.jor sickle cell syndrom.s. Th. m.dian age of th. patients was 31.25 years (extrem.s: 14 and 58 years) and th.y were predom.nantly fem.le (sex ratio m.F = 0.25). Two were on background th.rapy with.h.droxyurea. Am.ng th. four patients, th.re were two cases of acute lym.h.cytic leukem.a, including ALL3 in a 58-year-old SS wom.n and T-ALL2 in a 12-year-old SC. Th.n, a case of lym.h.cytic lym.h.m. in a 20-year-old SS m.n was reported and finally a case of ch.onic m.elocytic leukem.a in a 33-year-old wom.n of Sβ+ th.lassaem.a ph.notype. Conclusion: To furth.r report th.s coexistence, it is th.refore essential to system.tically consider h.m.tological m.lignancies during m.jor sickle cell syndrom.s even if th.re are sim.larities in th. sym.tom.tology of th.se two serious path.logical situations.
