Background Si.ce the late 1990s, bi.headed carps(largely si.ver carp [Hypophthalmi.hthys moli.ri.] but also bi.head carp [H. nobi.i.]) have establi.hed throughout the lower Mi.si.si.pi.Ri.er basi.. Usi.g previ.usly studi.d oxbow lakes i. the lower Whi.e Ri.er basi., Arkansas, we compared current(2017, “post-carp” establi.hment) fi.h assemblages to hi.tori.al(2002, “pre-carp” establi.hment) fi.h assemblages. Fi.h assemblages were comprehensi.ely assessed usi.g multi.le gears, i.cludi.g boat electrofi.hi.g, mi.i.fyke nets, and experi.ental small-mesh gi.l *** T-tests suggested that fi.h assemblage i.di.es of ri.hness, di.ersi.y, evenness, and domi.ance were often greater(P i.g the post-carp peri.d as reflected by boat electrofi.hi.g and experi.ental gi.l nets. However, all i.di.es were generally si.i.ar(P > 0.05) between the pre-carp and post-carp peri.d wi.h fi.h assemblages depi.ted usi.g mi.i.fyke nets. Nonmetri. multi.i.ensi.nal scali.g analyses i.di.ated that fi.h assemblages di.fered structurally between pre-carp and post-carp peri.ds. Assemblage di.ferences were li.ked to both small and large abundance changes for more than 20 speci.s. Abundances of gi.zard shad(Dorosoma cepedi.num), emerald shi.er(Notropi. atheri.oi.es), pugnose mi.now(Opsopoeodus emi.i.e), crappi.s(Pomoxi. spp.), bluegi.l(Lepomi. macrochi.us), orangespotted sunfi.h(L. humi.i.), and yellow bass(Morone mi.si.si.pi.nsi.) decli.ed between the pre-carp and postcarp peri.ds. Conversely, abundances of weed shi.er(N. texanus), palli. shi.er(Hybopsi. amni.), longear sunfi.h(L. megaloti.), buffalofi.hes(i.ti.bus spp.), and gars(Lepi.osteus spp.) generally i.creased duri.g the same *** Although not possi.le to conclude assemblage shi.ts were enti.ely related to bi.headed carps due to the absence of an appropri.te reference system where carps di. not establi.h, the wi.e establi.hment of these carps i. one of the most pervasi.e changes to have occurred i. the lower Whi.e

Accurately approxi.ati.g hi.her order deri.ati.es i. an i.herently di.fi.ult problem. i. i. shown that a random vari.ble shape parameter strategy can i.prove the accuracy of approxi.ati.g hi.her order deri.ati.es wi.h Radi.l Basi. Functi.n methods. The method i. used to solve fourth order boundary value problems. The use and locati.n of ghost poi.ts are exami.ed i. order to enforce the extra boundary condi.i.ns that are necessary to make a fourth-order problem well posed. The use of ghost poi.ts versus solvi.g an overdetermi.ed li.ear system vi. least squares i. studi.d. For a general fourth-order boundary value problem, the recommended approach i. to ei.her use one of two novel sets of ghost centers i.troduced here or else to use a least squares approach. When usi.g ei.her ghost centers or least squares, the random vari.ble shape parameter strategy results i. si.ni.i.antly better accuracy than when a constant shape parameter i. used.

The Ti.i.g of Pri.ary Neurosurgi.al Repai. and Wound-Si.e i.fecti.n i. Chi.dren wi.h Myelomeni.gocele

引用

Open Journal of Modern Neurosurgery 2024年第2期14卷 137-148页

作者： joseph O. Obande Paul T. Bi.rus Eli.abeth i. Obande Di.i.i.n of Neurosurgery Department of Surgery University of Abuja Teaching Hospital Abuja Nigeria Post-Basi. School of Cri.i.al Care Nursi.g University of Abuja Teaching Hospital Abuja Nigeria

Background: The opti.al ti.e to closure of a newborn wi.h a myelomeni.gocele has been the focus of a number of evaluati.ns. The Ti.i.g of pri.ary surgery has recei.ed si.ni.i.ant attenti.n due to i.s relati.nshi. to repai.-si.e i.fecti.n that can lead to i.creased morbi.i.y and prolonged hospi.al stays. i. i. on thi. basi. that recommendati.ns have uti.i.ed 48 - 72 hours post bi.th as i.eal ti.e of closure. Thi. i. not only prevent i.fecti.n at the si.e but also prevent ventri.uli.i. and neural structure damage. We therefore, hypothesi.ed an i.crease i. wound i.fecti.n rates i. those pati.nts wi.h delays i. myelomeni.gocele repai.. Methods: We retrospecti.ely revi.wed the records of 103 chi.dren wi.h myelomeni.gocele treated between 2016 and 2023. At di.charge the pati.nts were followed up at the post-operati.e cli.i. vi.i. 2 weeks later. Chi.dren were assi.ned to 1 of 2 groups, those who underwent pri.ary neurosurgi.al repai. wi.hi. 72 hours of deli.ery (Group 1) and those undergoi.g repai. after 72 hours (Group 2). We compared the i.fecti.n rates. Results: 103 chi.dren who underwent myelomeni.gocele repai. were i.enti.i.d, wi.h a medi.n ti.e from bi.th to treatment of 1 day. Ei.ht (7.8 %) pati.nts were noted to have post-repai. surgi.al si.e compli.ati.ns. There was no si.ni.i.ant di.ference i. rates of i.fecti.n between Group 1 and Group 2 repai. ti.es. The presence of i.fecti.n was associ.ted i.creased length of stay when compared to neonates wi.hout i.fecti.n. Conclusi.n: i. chi.dren wi.h myelomeni.gocele, the ti.i.g of pri.ary neurosurgi.al repai. appears not to have a si.ni.i.ant i.pact on surgi.al si.e i.fecti.n. Closure of the spi.al lesi.n wi.hi. the fi.st 72 hours of li.e may be more favorable for neural damage preventi.n. These results suggest that early myelomeni.gocele repai. may not i.part si.ni.i.antly on the rate of wound-si.e i.fecti.n.
