Background: i.adequate antenatal care, both i. coverage and standard, has been li.ked wi.h poor pregnancy outcomes. i. a resource poor setti.g, home deli.ery i. consi.ered very cheap, but the possi.le outcome of such pregnanci.s has been a subject of i.terest. Thi. study evaluated the associ.ti.n of booki.g status wi.h pregnancy outcomes. Objecti.es: To exami.e the factors that i.fluence booki.g and i.pact of the booki.g status on pregnancy outcomes. Methods: Thi. was a hospi.al-based prospecti.e cohort study of 240 (120 booked and 120 un-booked) pregnant mothers selected through systemati. random sampli.g. The study was carri.d out at the Department of Obstetri.s and Gynaecology, Alex Ekwueme Federal Uni.ersi.y Teachi.g Hospi.al Abakali.i. Ni.eri.. Chi.square test, t-test and logi.ti. regressi.n were used for analysi.. Results: The mean age of the parti.i.ants was 30.39 ± 5.05 years and 29.05 ± 6.36 years respecti.ely for the booked and unbooked. Mari.al status (OR = 6.35, 95% Ci.= 1.24 - 32.59), educati.nal status (OR = 36.40, 95% Ci.= 5.26-152.83), place of resi.ence (OR = 0.15, 95% Ci.= 0.06 - 0.41), partner’s support (OR = 0.05, 95% Ci.= 0.01 - 0.37), fami.y support (OR = 0.03, 95% Ci.= 0.01 - 0.13), mode of deli.ery (OR = 0.23, 95% Ci.= 0.12 - 0.46), APGAR score i. fi.st mi.ute (OR = 6.02, 95% Ci.= 2.45 - 14.83) and NBi.U admi.si.n (OR = 3.75, 95% Ci.= 1.67 - 8.43) were associ.ted wi.h booked status. However, bei.g unmarri.d, nulli.ari.y/grandmulti.ari.y, low level of educati.n, blue colar jobs, low i.come, rural dwelli.g and poor partner and poor fami.y support were associ.ted wi.h the unbooked. The booked parturi.nts had a better peri.atal outcome compared the unbooked. Conclusi.n/Recommendati.n: There was hi.h prevalence of operati.e deli.eri.s, peri.atal morbi.i.y and mortali.y among the unbooked mothers. Gi.l chi.d educati.n, employment and poverty allevi.ti.n would i.prove antenatal care uti.i.ati.n.

Wrought and laser powder bed fusi.n （LPBF） Ti.6Al-4V speci.ens were comparati.ely evaluated， wi.h the objecti.e to determi.e LPBF Ti.6-4’s sui.abi.i.y for bi.medi.al appli.ati.ns. Testi.g i.cluded nanoi.dentati.n， cycli. polari.ati.n i. si.ulated body flui. （SBF， 37 ℃ ）， and dry and SBF “Ball-on-Plate” sli.i.g. Wrought Ti.6-4 exhi.i.ed a lamellar （α+β） mi.rostructure， whereas LPBF di.played a fi.e-grai.ed α'-martensi.e mi.rostructure. LPBF Ti.6-4 demonstrated ～3% hi.her i.dentati.n modulus and ～32% hi.her hardness， whi.e wrought Ti.6-4 showed ～8% hi.her plasti.i.y. Both alloys exhi.i.ed low corrosi.n rates (10–5mA/cm2order) and true passi.i.y (10–4mA/cm2order). No locali.ed corrosi.n was observed i. ei.her alloy， except for occasi.nal metastable pi.ti.g i. the LPBF alloy. However， LPBF Ti.6-4 presented hi.her corrosi.n rate and passi.e current， ascri.ed to i.s martensi.i. structure. Duri.g dry sli.i.g， LPBF Ti.6-4 exhi.i.ed ～14% lower volume loss compared to wrought Ti.6-4. Sli.i.g i. SBF i.creased volume losses for both alloys， wi.h wear resi.tances nearly equali.ed， as the advantage of LPBF Ti.6-4 decreased due to more i.tensi.e wear-accelerated corrosi.n i.duced by the stressed martensi.e. Overall， the results demonstrate the sui.abi.i.y of LPBF Ti.6Al-4V for bi.medi.al uses.

BACKGROUND: Pai. management followi.g caesarean secti.n sti.l remai.s a challenge i. our envi.onment.

OBJECTi.E: To compare the effi.acy and safety of combi.ed rectal di.lofenac and i.tramuscular pentazoci.e wi.h i.tramuscular pentazoci.e alone for post operati.e pai. control followi.g lower segment caesarean secti.n. METHODOLOGY: A total of 120 women who met the selecti.n cri.eri. scheduled for caesarean secti.n under spi.al anaesthesi. wi.h bupi.acai.e were randomi.ed i.to two equal groups to recei.e ei.her 75 mg di.lofenac supposi.ory 12 hourly for 24 hours or one anusol supposi.ory (the placebo) 12 hourly for 24 hours. Both groups recei.ed pentazoci.e as pri.ary analgesi.. RESULT: The pri.ary outcome measure i. the proporti.n of pati.nts wi.h severe pai. at 24 hours usi.g the vi.ual analogue rati.g scale. Secondary outcome measures are the ti.e from surgery to ambulati.n, Passage of flatus, maternal sati.facti.n and presence of compli.ati.ns. Stati.ti.al analysi. was done usi.g spss versi.n 22 and graph pad stati.ti.al package. Student T-test was used for conti.uous vari.bles whereas chi.square was used for categori.al vari.bles P CONCLUSi.N: Adjuvant rectal di.lofenac i. superi.r to pentazoci.e alone i. the management of pai. after caesarean secti.n. Less number of pati.nts had moderate to severe pai. at 24 hours post operati.n. Maternal sati.facti.n i. relati.n to pai. management i. better wi.h di.lofenac supposi.ory. The levels of compli.ati.ns were comparable i. both groups.
