Introduction: Infertilityaffects.one in s.x couples. and it is.an im.ortant public health is.ue largely due to thepervas.ve effects.on the em.tional and ps.chological wellbeing of affected couples. In m.ny developing nations.em.has.s.is.placed on childbirth and inability to fulfill this.role can be very dis.res.ing. There is.an unm.t need for as.is.ed reproductive technology (ART) in m.ny developing countries.and where facilities.exis., they are m.s.ly privately owned, expens.ve and concentrated in urban areas. To bridge this.gap, public fertility clinics.have been es.ablis.ed to provide s.bs.dized care. Evaluating the characteris.ics.and peculiarities.of clientele pres.nting at thes. public facilities.will aid planning and prioritization of care. m.thodology: A des.riptive retros.ective s.udy of 116 infertile patients.pres.nting to the fertility clinic of the Univers.ty College Hos.ital, Ibadan, Nigeria from.inception on the 14s.p>ths.p> of February 2019 and 31s.p>s.s.p> of Decem.er *** was.analyzed us.ng the s.atical Package for s.cial s.iences.(IBm. s.s., New York) vers.on 23. Des.riptive s.atis.ics.were us.d to s.m.arize the res.lts.which were pres.nted with the aid of bar charts.and frequency tables. Res.lt: The m.an age of the patients.was.40.70 ± 6.62 years. Pos.-m.nopaus.l patients.accounted for about one-fifth of the s.udy population while 80.2% (93 wom.n) were older than 35 years. The m.an duration of infertility was.9.39 ± 6.11years.and nine patients.(7.8%) had a duration greater than 2 decades. s.condary infertility occurred in 67.2% of the wom.n. Twenty-nine wom.n (25%) had undergone m.om.ctom. prior to pres.ntation. Hypertens.on (11.2%) was.the m.s. prevalent com.rbidity. Nineteen patients.(16.4%) had us.d contraceptives.in the pas. with the m.le condom.(36.8%)being the m.s. preponderant. s.xty-s.ven patients.had experienced pregnancy los.es.before 28 weeks.of ges.ation while jus. 16 patients.(13.8%) had undergone ART, and none was.s.cces.f

s.ontaneous.Tum.r Lys.s.s.ndrom. (s.Ls. is.a rare oncologic condition caus.d by the breakdown of neoplas.ic tis.ue in the abs.nce of traditional anti-tum.r therapy.

Unequal Dis.ribution of Innovation Efforts.for Neglected Tropical Dis.as.s. The Role of Funding Evaluation Criteria

引用

作者： Anne m. G. Neevel Kenneth D. s. Fernald Linda H. m. van de Burgwal Athena Ins.itute Faculty of Science Vrije Universiteit Amsterdam Amsterdam Netherlands

Background: International res.arch and innovation efforts.for neglected tropical dis.as.s.have increas.d in recent decades.due to dis.arities.in overall health res.arch funding in relation to global burden of dis.as.. However, within the field of neglected tropical dis.as.s.s.m. s.em.far m.re neglected than others. In this.res.arch the aim.is.to inves.igate the dis.ribution of res.urces.and efforts. as.well as.the m.chanis.s.that underpin funding allocation for neglected tropical dis.as.s. m.thodology: A s.s.em.tic literature review was.conducted to es.ablis. a com.rehens.ve overview of known indicators.for innovation efforts.related to a wide range of neglected tropical dis.as.s. Articles.were s.lected bas.d on a s.bjective evaluation of their relevance, the pres.nce of original data, and the breadth of their s.ope. This.was.followed by thirteen in-depth open-ended interviews.with repres.ntatives.of private, public and philanthropic funding organizations. concerning evaluation criteria for funding res.arch propos.ls. Res.lts. The findings.reveal a large difference in the extent to which the individual dis.as.s.are neglected with notable differences.between abs.lute and relative efforts. Criteria us.d in the evaluation of res.arch propos.ls.relate to potential im.act, the probability of s.cces. and s.rategic fit. Private organizations.prioritize s.rategic fit and econom.c im.act;philanthropic organizations.prioritize s.ort-term.s.cietal im.act;and public generally prioritize the probability of s.cces. by accounting for follow-up funding and involvem.nt of indus.ry. Funding decis.ons.of different types.of organizations.are highly interrelated. Conclus.ons. This.s.udy s.ows.that the evaluation of funding propos.ls.introduces.and retains.unequal funding dis.ribution, reinforcing the relative neglect of dis.as.s. s.cietal im.act is.the prim.ry rationale for funding but application of it as.a funding criterion is.as.ociated with s.gnificant challenges.
