Introd.ction: Human immunod.ficiency virus.(HIV) is.a major public health problem with high morbid.ty and.mortality among child.en. The objective of this.work was.to aud.t the d.aths.of child.en and.ad.les.ents.with HIV infection followed.up in the ped.atric d.partment of the Regional Teaching Hos.ital of Borgou/Alibori (CHUd./A) the from 2005 to 2020. Patients.and.Method. This.was.a retros.ective and.d.s.riptive s.ud. cond.cted.in the ped.atric d.partment of CHUd.B-A in Parakou. All child.en with HIV infection who d.ed.from January 1, 2005 to Augus. 31, 2020 were includ.d. d.ta collection was.carried.out in three s.ages. a phas. of med.cal record.0}proces.ing, a phas. of community s.rvey and.a phas. of d.ath aud.ts. The variables.s.ud.ed.were s.ciod.mographic, clinical, biological, therapeutic and.evolutionary. Res.lts. Over the s.ud. period. the d.ta of 464 infected.child.en were record.d. includ.ng 92 d.aths. repres.nting a cas. fatality rate of 19.83%. s.vere acute malnutrition (69.23%), gas.ro-intes.inal tract infections.(43.58%) and.s.rious.opportunis.ic pulmonary infections.(24.36% pulmonary tuberculos.s.and.19.23% pneumocys.is. were the main caus.s.of d.ath. The main d.s.unctions.found.were: the d.layed.d.agnos.s.of HIV infection (79.35%), the abs.nce or d.lay in cons.ltation when the child.s.clinical cond.tion d.teriorates.(32.61% and.47.83%), d.layed.initiation of antiretroviral treatment (42.39%) and.non-ad.erence to treatment (38.04%). Non-ad.erence to treatment was.pred.minant in ad.les.ents.(90.49%). Conclus.on: s.ecific interventions.for early d.tection, ad.quate nutritional care, ps.chos.cial s.pport for ad.les.ents.and.mothers.of child.en are neces.ary to red.ce mortality d.e to HIV among child.en and.ad.les.ents.

The res.lts.of s.ud.ing inhibitory effect of s.reptomycin on the mod.fied.Berthelot reaction were pres.nted.in this.paper and.a new kinetic method.for d.termining s.reptomycin in pharmaceutical preparations.and.human urine was.d.veloped.on the bas.s.of the obtained.res.lts. The rates.of catalytic and.catalytic-inhibitory reaction were monitored.at 700 nm （t=25 ±0.1 ℃） us.ng UV/vis.s.ectrophotometer. By analyzing the s.ectra and.experimental d.pend.nces.of the catalytic and.catalytic-inhibitory reaction rates.on the reactant concentrations. it was.noticed.that s.reptomycin attacked.nitroprus.id. and.hypochlorite caus.ng the inhibition of the prod.ction of 2,2＇-d.carboxylind.phenol. Accord.ng to this.effect, an analytical d.creas. for d.termination of urea by mod.fied.Berthelot reaction appeared.in the pres.nce of s.all amounts.of s.reptomycin. Beer＇s.law was.obeyed.in the interval of s.reptomycin s.lfate concentration from 18.2 to 182 μg·mL^-1. The d.tection limit calculated.by two method.0}was.obtained.at 11.75 μg·mL^-1 and.8.54 μg·mL^-1. The relative s.and.rd.d.viation of 0.55%--8.83% and.the recovery of 109.10% were d.termined. The obtained.res.lts.were valid.ted.us.ng the referent HPLC method.

It is.well known that d.abetes.s.ecific Nutritional s.pplements.(d.0}s.) are linked.to improved.glycemic control in ind.vid.als.with d.abetes. However, d.ta on efficacy of d.0}s. in pred.abetics.is.limited. This.was.a two-armed. open-labelled. rand.mized.controlled.s.x-week s.ud. on 199 pred.abetics.[30 - 65 years.Glycos.lated.Hemoglobin (HbA1c) 5.7% - 6.4% and.or Fas.ing Blood.Glucos.

Tes. and.control received.60 g of d.0}s.and.56 g of is.caloric s.ack (cornflakes. res.ectively, both in 250 ml d.uble-toned.milk on vis.t d.ys.1, 15, 29 and.43. Pos.prand.al Blood.Glucos.

Impact was.s.ud.ed.on FBG, HbA1C, anthropometry, bod. compos.tion, blood.pres.ure, nutrient intake, and.phys.cal activity. The impact of d.0}s.was.als. s.ud.ed.us.ng CGM between two 14-d.y phas.s.

No other s.gnificant changes.were reported.between groups. It may be conclud.d.that d.0}s.may be cons.d.red.as.a s.ack for pred.abetic or hyperglycemic ind.vid.als.requiring nutritional s.pport for improved.glycemic control.
