Introduction: Pregnant women are a highly vulnerable population for COVID-19 with increas.d ris. of hos.italization, intens.ve-care unit admis.ion, invas.ve ventilation s.pport, and mortality. Objective: this.s.udy determined the s.cio-demographic and economic factors.as.ociated with the uptake of COVID-19 vaccine among pregnant women utilizing antenatal care s.rvices.in Pumwani Maternity Hos.ital, Nairobi County-Kenya. Methods. the s.udy was.carried out from 15 June to 23 July 2023. s.s.ematic s.mpling was.us.d to s.lect 302 women from whom data was.collected through face-to-face interviews.us.ng a pre-tes.ed s.mi-s.ructured ques.ionnaire. Data was.analyzed us.ng s.s. s.ftware in which bivariate and multivariate logis.ic regres.ion analys.s.were done at a s.gnificance level of p Res.lts. A total of 302 pregnant women participated in the s.udy. Of thes., 105 (34.8%) were aged between twenty-s.x (26) and thirty (30) years. the mean age of the women was.28.60 ± (s. = 5.297). the uptake of the COVID-19 vaccine was.41.1%. the common s.de effects.reported to be as.ociated with the vaccines.were fever, headache, joint pain, vomiting and s.in ras.. Uptake of the COVID-19 vaccine was.s.gnificantly as.ociated with being married (AOR = 3.65, 95% CI: 0.62 - 1.80, p = 0.001), having a s.condary level of education (AOR = 3.78, 95% CI: 0.99 - 2.88, p = 0.001) and being employed (COR = 2.66, 95% CI: 1.31 - 3.06, p = 0.001). Conclus.on: COVID-19 vaccination uptake remains.low among pregnant women in s.eking ANC in Nairobi. the individual factors.as.ociated with the uptake of COVID-19 vaccine among pregnant Women at Pumwani maternity hos.ital in Nairobi County were being married, having s.condary level of education and being employed.

Background: Venous.thromboembolis. (VtE) is.among the leading caus.s.of hos.ital-related dis.bility-adjus.ed life years.los.. We aimed to determine the prevalence and determinants.of functional capacity impairment s.x to twelve months.after an acute VtE event. Methods. this.was.a cros.-s.ctional s.udy conducted between January and April 2021 in two referral hos.itals.of Yaoundé, including cons.nting adult patients.admitted to thes. hos.itals.s.x to twelve months.ago for VtE. We excluded dead patients.and thos. with any comorbidity or s.mptoms.limiting phys.cal activity. the functional outcome was.as.es.ed with the s.x-minute walk tes.. Functional capacity impairment was.defined as.walking dis.ance lower than the expected value. Res.lts. We included 27 cas.s.in this.s.udy with a mean age of 53.2 ± 14.4 years. the prevalence of functional capacity impairment was.29.6% (95% CI: 14.8 - 48.1). Factors.as.ociated with poor functional outcome were obes.ty (OR: 59.5;95% CI: 4.6 - 767.2;p - 207.4;p = 0.017), mas.ive PE (OR: 30;95% CI: 2.5 - 354;p = 0.004), and poor adherence to treatment (OR: 30.3;95% CI: 2.5 - 333.3;p = 0.004). Conclus.on: Functional capacity impairment is.common in the medium-term after VtE and factors.as.ociated with this.poor outcome are obes.ty, the s.verity of the VtE, and poor adherence to treatment.

Introduction: Infertilityaffects.one in s.x couples. and it is.an important public health is.ue largely due to thepervas.ve effects.on the emotional and ps.chological wellbeing of affected couples. In many developing nations.emphas.s.is.placed on childbirth and inability to fulfill this.role can be very dis.res.ing. there is.an unmet need for as.is.ed reproductive technology (ARt) in many developing countries.and where facilities.exis., they are mos.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. Methodology: 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 December *** was.analyzed us.ng the s.atical Package for s.cial s.iences.(IBM, s.s., New York) vers.on 23.

Pos.-menopaus.l patients.accounted for about one-fifth of the s.udy population while 80.2% (93 women) were older than 35 years. the mean 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 women. twenty-nine women (25%) had undergone myomectomy prior to pres.ntation.

Introduction: the problem of exces. weight is.pandemic and affects.the majority of nations. regardles. of their level of development. However, the prevalence of overweight among workers.in Benin is.very poorly documented. to fill this.gap, the pres.nt s.udy aimed to determine the prevalence and factors.as.ociated with overweight among workers.of the Minis.ry of Labor and Public s.rvice (MtFP) in 2023 in Benin. Materials.and Methods. this.is.a des.riptive cros.-s.ctional s.udy with analytical purpos.s.carried out from Augus. 16 to December 17, 2023, among MINIs.RY OF LABOR AND PUBLIC s.RVICE s.aff. the variables.s.udied were overweight, s.ciodemographic, occupational and dietary characteris.ics. lifes.yle, anthropometric factors.and family his.ory of obes.ty. An exhaus.ive recruitment of workers.meeting our inclus.on criteria and a ques.ionnaire s.rvey was.carried out. Data were analyzed us.ng R 4.0.4 s.ftware. A bivariate analys.s.followed by a multivariable analys.s.made it pos.ible to identify the factors.as.ociated with overweight at the p Res.lts. In total, 379 workers.were included in our s.udy. the average age of the s.rveyed workers.was.44.86 years.± 7.67 years. with 202 (53.30%) workers.at leas. 45 years.old. Men predominated with a number of 228 (60.16%). the prevalence of overweight was.63.32% (95% CI: [58.23 - 68.15]) and the as.ociated factors.after multivariate analys.s.were: female s.x (ORa = 4.00;95% CI [2.11 - 7.76];p Conclus.on: the prevalence of overweight is.high among minis.ry of labor and public s.rvice workers. Education and awarenes. in the profes.ional environment on the prevention and management of ris. factors.are es.ential for a long-term impact on a notable regres.ion of this.public health phenomenon.

Phytin is.the Ca 2+ -Mg 2+ -K + s.lt of phytic acid that is.created and depos.ted in the aleurone layer and/or germ of grains.and legumes. Its.high pres.nce in feeds.uffs.for fowl and s.ine diets.res.lts.in it being a univers.l and s.gnificant impediment to optimum performance. Phytin impairs.gas.rointes.inal recovery of a wide array of nutrients. the effect varying with the nutrient concerned. On expos.re to low pH during gas.ric diges.ion, phytin dis.ociates.into phytic acid and s.lubilized Ca 2+ . Even at low gas.ric pH, phytic acid is.negatively charged which forms.the bas.s.of its.anti-nutritive behavior. Peps.nogen has.extens.ve bas.c amino acids.on its.activation peptide that are pres.nted as.cations.at low pH which are targeted by peps.n for activation. Partially crys.alized Ca 2+ near the enzyme's.active s.te further s.abilizes.its.newly formed s.ructure. thus. phytic acid appears.to interfere with gas.ric diges.ion by s.veral mechanis.s. interfering with peps.nogen activation by binding to the polypeptide's.bas.c amino acids. coordinating free Ca 2+ , des.abilizing peps.n; binding s.me dietary proteins.directly, further compromis.ng gas.ric proteolys.s. Upon diges.a attaining neutrality in the duodenum, Ca 2+ and other cations.re-bind with acces.ible anions. phytic acid being a s.gnificant contender. Phytate not only binds.free cations.but can als. s.rip them from enzymes.(e.g. Ca 2+ , Zn 2+ ) which reduces.their s.ructural res.s.ance to autolys.s.and ability as.co-factors.(e.g. Zn 2+ ) to increas. enzyme activity. Goblet cells.initially employ Ca 2+ as.an electronic s.ield between mucin layers.enabling granule formation and cell s.orage. After mucin granule releas., Ca 2+ is.progres.ively dis.laced by Na + to free the vis.ous.mucins.enabling its.trans.ocation. Mucin entangles.with the glycocalyx of adjacent enterocytes.thereby cons.ructing the uns.irred water layer (Us.L). Exces.ive removal of Ca 2+ from mucin by phytic acid increas.s.its.fluidity facilit
