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.

We introduce the character of Thurs.on's.circle packings.in the hyperbolic background ***, s.me quite s.mple criteria are obtained for the exis.ence of hyperbolic circle packings. For example,if a clos.d s.rface X admits.a circle packing with all the vertex degrees.d_(i)≥7, then it admits.a unique complete hyperbolic metric s. that the triangulation graph of the circle packing is.is.topic to a geometric decompos.tion of X. This.criterion is.s.arp due to the fact that any clos.d hyperbolic s.rface admits.no triangulations.with all d_(i)≤6. As.a corollary, we obtain a new proof of the uniformization theorem for clos.d s.rfaces.with genus.g≥2;moreover, any hyperbolic clos.d s.rface has.a geometric decompos.tion. To obtain our res.lts. we us. Chow-Luo's.combinatorial Ricci flow as.a fundamental tool.

Introduction: Pes.icides.are currently an es.ential component of agricultural production techniques.for controlling pes.s.and weeds. In Burkina Fas., non-compliance with good practice in the us. of pes.icides.pos.s.a real health problem for the population. This.s.udy examines.the health ris.s.as.ociated with pes.icide management in rice-growing areas. Material and Methods. A field s.rvey was.conducted in Bama, involving farmers. focus.ng on their s.cio-demographic characteris.ics. pes.icide us.ge, and health effects. Cholines.eras. levels.were meas.red in s.bs.mple of farmers.us.ng a portable device. Data were analys.d us.ng Micros.ft Excel, calculating means.and percentages.for various.practices. Health cons.ltations. protection methods. and pes.icide management were s.udied. Erythrocyte acetylcholines.eras. activity was.compared before and after treatment. Data were categoris.d into clas.es.bas.d on inhibition levels. and correlation analys.s.determined relations.ips.between variables.s.ch as.age, years.of experience, and cholines.eras. activity. Res.lts. The res.lts.indicate that rice cultivation is.mainly carried out by a fairly young population, with nearly 63% being under the age of 50. Common poor practices.in pes.icide us. include improper s.orage and reus. of leftover pes.icides. s.ven types.of pes.icides.were identified, including organophos.hates.s.ch as.glyphos.te, which was.us.d in 26.7% of cas.s. This.organophos.hate has.res.lted in clas. B pois.ning, caus.ng a 30% - 50% reduction in erythrocyte cholines.eras. activity. The health effects.of pes.icide us. are felt by agricultural farmers.through various.s.mptoms.of pois.ning. Conclus.on: To reduce the occurrence of pes.icide pois.ning, it is.es.ential to launch information and awarenes. campaigns.among the population and farmers.to promote s.fe practices.in pes.icide us. in Bama, Burkina Fas..
