1Diversity and host assemblage of avian haemosporidians in different terrestrial ecoregions of Peru显示文摘Characterizing the diversity and structure of host–parasite communities is crucial to understandingtheir eco-evolutionary dynamics.Malaria and related haemosporidian parasites are responsible forfitness loss and mortality in bird species worldwide.However,despite exhibiting the greatest ornithologicalbiodiversity,avian haemosporidians from Neotropical regions are quite unexplored.Here,we analyze the genetic diversity of bird haemosporidian parasites(Plasmodium andHaemoproteus)in 1,336 individuals belonging to 206 bird species to explore for differences in diversityof parasite lineages and bird species across 5 well-differentiated Peruvian ecoregions.Wedetected 70 different haemosporidian lineages infecting 74 bird species.We showed that 25 out ofthe 70 haplotypes had not been previously recorded.Moreover,we also identified 81 new host–parasite interactions representing new host records for these haemosporidian parasites.Our outcomesrevealed that the effective diversity(as well as the richness,abundance,and Shannon–Weaver index)for both birds and parasite lineages was higher in Amazon basin ecoregions.Furthermore,we also showed that ecoregions with greater diversity of bird species also had highparasite richness,hence suggesting that host community is crucial in explaining parasite richness.Generalist parasites were found in ecoregions with lower bird diversity,implying that the abundanceand richness of hosts may shape the exploitation strategy followed by haemosporidian parasites.These outcomes reveal that Neotropical region is a major reservoir of unidentified haemosporidianlineages.Further studies analyzing host distribution and specificity of these parasites inthe tropics will provide important knowledge about phylogenetic relationships,phylogeography,and patterns of evolution and distribution of haemosporidian parasites.Luz GARCIA-LONGORIA Jaime MURIEL Sergio MAGALLANES Zaira Hellen VILLA-GALARCE Leonila RICOPA Wilson Giancarlo INGA-DIAZ Esteban FONG Daniel VECCO Cesar GUERRA-SALDANA Teresa SALAS-RENGIFO Wendy FLORES-SAAVEDRA Kathya ESPINOZA Carlos MENDOZA Blanca SALDANA Manuel GONZALEZ-BLAZQUEZ Henry GONZALES-PINEDO Charlene LUJAN-VEGA Carlos Alberto Del AGUILA Yessica VILCA-HERRERA Carlos Alberto PINEDA Carmen REATEGUI Jorge Manuel CARDENAS-CALLIRGOS JoseAlberto IANNACONE Jorge Luis MENDOZA Ravinder NMSEHGAL Alfonso MARZAL 2022Current Zoology2022,68,1:0
2Surgical outcomes and their relation to the number of prior episodes of diverticulitis显示文摘Purpose:We aimed to investigate the relationship between the number of prior episodes of diverticulitis and outcomes of sigmoid colectomy.Methods:After institutional review board approval,a retrospective review was undertaken based on records of patients who underwent sigmoid resection with anastomosis for diverticulitis between 4 May 2007 and 29 February 2012.Patients were divided into two groups:0–3 attacks(group 1)and4 attacks(group 2).Statistical analyses were performed to determine whether the groups differed on demographic,intra-operative and postoperative variables.Results:We identified 247 patients who underwent sigmoid colectomy for diverticulitis(45 open,202 laparoscopic).The two groups did not differ significantly in age,gender,American Society of Anesthesiologists score,past surgical history,body mass index,length of stay,use of a stoma or number of prior hospitalizations for diverticulitis.Group 1 had a higher rate of abscesses(30.6 vs 6.8%,P<0.001)and fistulas(19.4 vs 0.9%,P<0.001);a longer operative time(190.1 vs 166.3 min,P=0.0024);and higher rates of postoperative complications(45.8 vs 23.3%,P<0.001)and conversion(17.1 vs 4.4%,P=0.0091).The most common surgical complications in groups 1 and 2 were wound infection(35 vs 10)and ileus(20 vs 8).Based on multivariate regression analysis,4 attacks were independently correlated with a lower complication rate(odds ratio=0.512,95%confidence interval=0.266–0.987,P=0.046).Conclusions:Patients who had4 previous attacks of diverticulitis had fewer postoperative complications.Shota Takano Cesar Reategui Giovanna da Silva David J.Maron Steven D.Wexner Eric G.Weiss 2013Gastroenterology Report2013,1,1:0
