BACKGROUND: Tears of the geni.al tract are lesi.ns resulti.g from the breakage of the conti.ui.y of the lower geni.al tract duri.g chi.dbi.th. These i.j.ri.s are associ.ted wi.h hi.h maternal morbi.i.y or mortali.y i. severe, poorly managed or delayed i. repai.. i. i. a frequent compli.ati.n of vagi.al deli.ery. Thi. study was ai.ed at determi.i.g the prevalence, demographi. characteri.ti.s, ri.k factors, patterns and the t-term maternal outcomes of lower geni.al tract i.j.ri.s i. the labour room and the post-natal ward of the Bamenda Regi.nal Hospi.al. METHODS: Thi. was a hospi.al-based cross-secti.nal study of women managed for geni.al tract i.j.ri.s followi.g vagi.al bi.th i. the Bamenda Regi.nal Hospi.al (BRH) from March 2019 to j.ly 2019. A non-probabi.i.ti., consecuti.e and exhausti.e sampli.g techni.ue was used to select parti.i.ants (sample si.e esti.ated at 237). Among those selected were women who had a vagi.al bi.th. However, the researchers’ i.terest was parti.ularly centered on the women who had geni.al tract i.j.ri.s. Data was collected usi.g a pretested questi.nnai.e and analyzed usi.g the SPSS versi.n 22 software. RESULTS: i. total, 310 parti.i.ants were i.cluded i. thi. study. The mean age of the parti.i.ants was 26.1 years (SD = 5.2), whi.e the medi.n age was 25 years (i.terquarti.e range = 22 - 29). Of the 310 parti.i.ants i.cluded i. the study, 128 developed a bi.th tract i.j.ry gi.i.g a prevalence of 41.3% (95% Ci. 35.8 - 47.0). The most common type of i.j.ry was spontaneous tears (33.9%), the maj.ri.y of whi.h were peri.eal (30.6%) compared to epi.i.tomi.s (7.4%). Most peri.eal tears were fi.st degree tears (23.2%) followed by second-degree tears (6.8%). Thi.d-degree peri.eal tears were rare (0.6%). We di. not have any cases of fourth-degree peri.eal tears. We also encountered a few cases of cervi.al tears (0.6%). The factors associ.ted wi.h bi.th tract i.j.ry were assessed usi.g bi.ari.te and multi.le logi.ti. regressi.n analysi.. On bi.ari.te

作者： j.red M. Wendte robert j. Schmi.z Department of Geneti.s University of Georgia Athens GA 30602 USA

Plants encode a di.erse repertoi.e of DNA methyltransferases that have speci.li.ed to target cytosi.es for methylati.n i. speci.i. sequence contexts. These i.clude the de novo methyltransferase, DOMAi.S REARRANGED METHYLTRANSFERASE 2 （DRM2）, whi.h methylates cytosi.es i. all sequence contexts through an RNA-gui.ed process, the CHROMOMETHYLASES （CMTs）, whi.h methylate CHH and CHG cytosi.es （where H i. A, T, or C）, and METHYLTRANSFERASE 1 （MET1）, whi.h mai.tai.s methylati.n of symmetri.al CG contexts. i. thi. revi.w, we di.cuss the sequence speci.i.i.i.s and targeti.g of each of these pathways. i. parti.ular, we hi.hli.ht recent studi.s that i.di.ate CMTs preferenti.lly target CWG or CWA/CAW moti.s （where W i.

Fi.ally, the i.i.i.ti.g events that lead to gene body methylati.n are di.cussed as a model i.lustrati.g how i.terde- pendent targeti.g of di.ferent si.enci.g pathways can potenti.te the establi.hment of off-target epi.lleles.

Obesi.y rates are i.creasi.g i. Cameroon. Obstetri. li.erature has recently focused on the ri.i.g i.ci.ence of compli.ati.ns wi.h i.creases i. wei.ht gai. i. pregnancy. Some of these compli.ati.ns i.clude gestati.nal di.betes, hypertensi.e di.orders, operati.e deli.eri.s, geni.al tract lacerati.ns and fetal bi.th trauma. Exami.i.g the effects of excess wei.ht gai. duri.g the course of pregnancy could help i.enti.y wei.ht gai. li.i.s. The i.sti.ute of Medi.i.e (i.M) was recommended by the World Health Organi.ati.n (WHO) to develop gui.eli.es for wei.ht gai. duri.g pregnancy and we desi.ned thi. study i. order to determi.e deli.ery outcomes when wei.ht i. gai.ed above these gui.eli.es. We also sought to know i. these gui.eli.es are appli.able i. our envi.onment. i. thi. cross-secti.nal analyti. desi.n, pre-pregnancy and i.tra-partum BMi. were calculated for all the parturi.nts who consented. They were classi.i.d i.to normal wei.ht gai. and excessi.e wei.ht gai. based on i.M recommendati.ns. Those i. the normal wei.ht gai. group were women wi.h BMi. that ranged between 18.5 kg/m2 and 30 kg/m2 and who gai.ed 9 - 16 kgs. Those who gai.ed wei.ht above these range were consi.ered as havi.g gai.ed excessi.e wei.ht duri.g pregnancy. They were all follow-up i. labor usi.g the partogram. We compared prepartum, i.tra-partum and post-partum outcomes i. the two groups by calculati.g odds rati.s (ORs), 95% confi.ence i.tervals and p values. One hundred and ten (110) overwei.ht women were matched agai.st the same number of women who had normal wei.ht gai.. There was no si.ni.i.ant di.ference between soci.l status, mari.al status as well as level of educati.nal and wei.ht gai. i. the two groups. Underwei.ht (BMi.p = 0.048).

Four hundred and fi.teen (415) women were enrolled;the mean age was 29 ± 7.8 years;the most represented age group was 24 -29 years. They were si.gle (36.14%), well educated (5 out of 10 had attai.ed uni.ersi.y level of educati.n), 61.20% revealed that thei. partners knew thei. Hi. status, 82.4% beli.ved that screeni.g for cancer of the cervi. was necessary for thei. status and 47.70% would want to be screened for some or all STi.. About 36.86% had the desi.e to have chi.dren, 57.1% of those who deli.ered di. not plan to have the pregnanci.s out of whi.h 82% would have wanted a modern method of contracepti.n but di. not have (82% unmet needs).
