Object.ve: Various nail disorders have been rep.rt.d in p.t.ent. wit. chronic kidney disease. However, few st.dies have invest.gat.d nail disorders in p.t.ent. wit. advanced chronic kidney disease. t.is st.dy focused on nail disorders seen in p.t.ent. wit. end-st.ge renal disease (ESRD) undergoing conservat.ve t.eat.ent. Met.ods: A case-cont.ol st.dy was conduct.d at.Baraha Medical Cit. in Khart.um St.t., Sudan. Dat. on p.t.ent. wit. ESRD who were on conservat.ve t.eat.ent.and p.esent.d for follow-up.bet.een March and Sep.ember 2021 were collect.d. p.t.ent.' demograp.ic feat.res, nail findings on clinical examinat.on, and laborat.ry result. were recorded. t.e obt.ined dat. were comp.red wit. t.ose on age- and sex-mat.hed healt.y individuals from t.e general p.p.lat.on. t.e chi-square t.st.and St.dent.t.t.st.were p.rformed t. analyze cat.gorical and numerical variables, resp.ct.vely. Result.: Dat. on 78 p.t.ent. wit. ESRD were st.died. t.eir mean age was 54.6 ± 17.6 years, and 45 (57.7%) were men. t.ese p.t.ent. were comp.red wit. 129 cont.ols. Nail disorders were seen in 65 (83.3%) ESRD p.t.ent. and 86 (66.6%) cont.ols (p.= 0.009). p.t.ent. wit. ESRD were found t. be at.increased relat.ve risk of develop.ng a wide sp.ct.um of nail disorders. An absent.lunula, half-and-half nails, nail dyst.op.y, t.rry's nails, onychomycosis, and koilonychia were t.e most.common disorders and were seen in 44 (56.4%), 13 (16.7%), 10 (12.8%), 9 (11.5%), 6 (7.7%), and 5 (6.4%) p.t.ent., resp.ct.vely. p.t.ent. wit.

t.e st.dy invest.gat.s long-t.rm changes in annual and seasonal rainfall p.t.erns in t.e Indira Sagar Region of Madhya p.adesh, India, from 1901 t. 2010. Agricult.re sust.inabilit., food sup.ly, nat.ral resource develop.ent. and hydrop.wer syst.m reliabilit. in t.e region rely heavily on monsoon rainfall. Mont.ly rainfall dat. from t.ree st.t.ons (East.Nimar, Barwani, and West.Nimar) were analyzed. Init.ally, t.e p.e-whit.ning met.od was ap.lied t. eliminat. serial correlat.on effect. from t.e rainfall dat. series. Subsequent.y, st.t.st.cal t.ends in annual and seasonal rainfall were assessed using bot. p.ramet.ic (st.dent.t.t.st. and non-p.ramet.ic t.st.
