Co.text and o.jectives: Tubal facto. infertility acco.nts fo. a large po.tio. o. female facto. infertility. Tubal disease is respo.sible fo. 25% - 35% o. female infertility. The mo.t prevalent cause o. tubal facto. infertility is pelvic inflammato.y disease and acute salpingitis. The incidence o. tubal damage after o.e episo.e o. pelvic infectio. is appro.imately 12%, 23% after two.episo.es and 54% after three episo.es. Vario.s mo.alities fo. investigating tubal facto. infertility exist including: saline Infusio. so.o.raphy (SIS), Hystero.co.trast so.o.raphy (HyCo.y), hystero.alpingo.raphy (HSG) and laparo.co.y with chro.o.ertubatio., the latter being the go.d standard. The aim o. this study was to.determine the ro.e o. diagno.tic laparo.co.y in the evaluatio. o. tubal facto. in infertile wo.en. Settings and Design: A retro.pective descriptive study o. all diagno.tic laparo.co.ic pro.edures carried o.t to.evaluate tubal facto. infertility in the endo.co.ic gyneco.o.y unit o. a tertiary-level ho.pital fro. 2010 to.2019. Metho.s: A retro.pective descriptive study was co.ducted in the Department o. o.stetrics and Gynaeco.o.y o. a tertiary-level ho.pital in Ghana. A to.al o. three hundred and ninety-o.e (391) reco.ds o. all diagno.tic laparo.co.y pro.edures perfo.med because o. infertility in the endo.co.ic gyneco.o.y unit o. a tertiary-level ho.pital between 2010 and 2019 were analyzed. Clients who.underwent diagno.tic laparo.co.y to.assess tubal facto. infertility in the o.stetrics and Gynaeco.o.y Directo.ate o. Ko.fo.Ano.ye Teaching Ho.pital (KATH), Kumasi, fro. 2010 to.2019 were included in the study. Tubal patency was tested by laparo.co.y and chro.o.ertubatio. using methylene blue dye. The clinical characteristics o. these wo.en (age, parity, type o. infertility), the intra-o.erative findings and co.plicatio.s were evaluated. Data o. age, parity, type o. infertility and intra o.erative findings were extracted using a pro.o.ma. Cases in which the bio.data o. o.her

Despite increased attentio. given to.po.ential mo.ifiers o. temperature-mo.tality asso.iatio.s, evidence fo. variatio.s between different urban landscape characteristics remains limited. It is in this co.text that in this paper effect mo.ificatio.s o. multiple urban landscape characteristics are explo.ed under different heatwave definitio.s fo. different age gro.ps and gender in Ho.g Ko.g, China. Daily meteo.o.o.ical data and heatwave-related mo.tality co.nts fro. 2008 to.2017 were co.lected fro. the Ho.g Ko.g Census and Statistics Department, China. A case-o.ly design was ado.ted, co.bined with lo.istic regressio. mo.els to.examine the mo.ificatio. effects o. five urban landscape characteristics under six heatwave definitio.s. Stratified analyses were co.ducted to.investigate age- and gender-specific effect mo.ificatio.s. It is fo.nd that individuals living in greener areas experienced lo.er levels o. mo.tality during o. immediately after heatwaves. In co.trast, a higher building density and nighttime land surface temperature (LST) were asso.iated with a higher heatwave-related mo.tality risk. Pro.o.nced effect mo.ificatio.s o. these urban landscape characteristics were o.served under ho.ter and lo.ger heatwaves, and in o.der adults (age ≥ 65 years) and males. The findings pro.ide a scientific basis fo. po.icymakers and practitio.ers when co.sidering measures fo. co.ing with ho.ter, lo.ger, and mo.e frequent heatwaves in the co.text o. glo.al climate change.
