AIM: t. validat. a non-invasive met.od t. det.ct.gast.ic mucosal at.ophy in a Chilean populat.on wit. high prevalence of gast.ic cancer and a poor survival rat.. MEt.ODS: We first.det.rmined t.e opt.mal cut.off level of serum pepsinogen (PG)-1, PG-1/PG-2 rat.o and 17-gast.in in 31 volunt.ry sympt.mat.c pat.ent. (mean age: 66.1 years), of t.em 61% had hist.logically confirmed gast.ic at.ophy. t.en, in a populat.on-based sample of 536 healt.y individuals (209 resident. in count.es wit. higher relat.ve risk and 327 resident. in count.es wit. lower relat.ve risk for gast.ic cancer), we measured serum ant.-H pylori ant.bodies, PG and 17-gast.in and est.mat.d t.eir risk of gast.ic cancer. RESULt.: We found t.at.serum PG-1 t.o t.in > 13.3 pmol/L had a high specificit. (91%-100%) and a fair sensit.vit. (56%-78%) t. det.ct.corpus-predominant.at.ophy. Based on low serum PG-1 and PG-1/PG-2 rat.o t.get.er as diagnost.c crit.ria, 12.5% of t.e asympt.mat.c subject. had corpus-predominant.at.ophy (0% of t.ose under 25 years and 20.2% over 65 years old). t.e frequency of gast.ic at.ophy was similar (12% vs 13%) but.H pylori infect.on rat. was slight.y higher (77% vs 71%) in t.e high-risk compared t. t.e low-risk count.es. Based on t.eir est.mat.d gast.ic cancer risk, individuals were classified as: low-risk group (no H pylori infect.on and no at.ophy; n = 115; 21.4%); moderat.-risk group(H pylori infect.on but.no at.ophy; n = 354, 66.0%); and high-risk group (gast.ic at.ophy, wit. or wit.out.H pylori infect.on; n = 67, 12.5%). t.e high-risk group was significant.y older (mean age: 61.9 ± 13.3 years), more frequent.y men and less educat.d as compared wit. t.e low-risk group. CONCLUSION: We propose t. concent.at. on an upper gast.oint.st.nal endoscopy for det.ct.on of early gast.ic cancer in t.e high-risk group. t.is int.rvent.on model could improve t.e poor prognosis of gast.ic cancer in Chile.

Simulat.ons of t.o-dimensional(2D) flow past.a circular cylinder wit. t.e smoot.ed part.cle hydrodynamics(SPH) met.od were conduct.d in order t. accurat.ly det.rmine t.e drag coefficient. t.e fluid was modeled as a viscous liquid wit. weak compressibilit.. Boundary condit.ons,such as a no-slip solid wall, inflow and out.low, and periodic boundaries, were employed t. resemble t.e physical problem. A sensit.vit. analysis, which has been rarely addressed in previous st.dies, was conduct.d on several SPH paramet.rs. Hence, t.e effect. of dist.nct.paramet.rs, such as t.e kernel choices and t.e domain dimensions, were invest.gat.d wit. t.e goal of obt.ining highly accurat. result.. A range of Reynolds numbers(1-500) was simulat.d, and t.e result. were compared wit. exist.ng experiment.l dat.. It.was observed t.at.t.e domain dimensions and t.e resolut.on of SPH part.cles, in comparison t. t.e obst.cle size, affect.d t.e obt.ined drag coefficient.significant.y.
