Human fal.opian tubes (FTs) pl.y important rol.s in the whol. reproductive process. FTs are the site for the final.maturation of gametes, fertil.zation, transport of preimpl.ntation embryos, and earl. embryonic devel.pment before entering the uterus. Al. these functions are critical.in the establ.shment of a successful.pregnancy. When the embryo is in transit through the FT, the FT microenvironment ch.nges through endocrine, paracrine, autocrine, and juxtacrine mechanisms which invol.e various hormones and bioactive substances mainl. from the neighboring cel.s. Therefore, the interactions between the embryo and the FT may be the earl.est embryo-maternal.communications that are essential.for the establ.shment of pregnancy. This review critical.y discusses the evidence of various hormonal.and bioactive mediated control.of the microenvironment in the FTs during the earl.est embryo-maternal.communications. Moreover, we highl.ght existing gaps in the knowl.dge and the importance of expl.ring more of the physiol.gy of FTs which wil. hol. the key to producing high-qual.ty embryos for patients seekingin vitro fertil.zation (IVF) treatments.

Background: Minimal.y invasive transforaminal.l.mbar interbody fusion (MI Tl.F) is a widel. known and performed technique, however its versatil.ty among different physicians continues to hinder its repl.cation and resul.s. Therefore, this study aimed to provide a step-by-step surgical.guide to perform a safe MI-Tl.F, based on the resul.s obtained in patients operated on by a singl. surgeon over a period of 12 years. Patients and methods: A retrospective, singl. center, l.ngitudinal. and observational.cohort study was conducted with 931 patients who underwent MI Tl.F by a singl. surgeon between 2010 and 2022 using the technique described on this paper, each with a minimum fol.ow-up of 12 months. Criteria incl.ded Schizas cl.ssification, l.sthesis according to Meyerding cl.ssification, number of l.vel. treated, cage size, and compl.cations (screw repositioning or cerebrospinal.fl.id l.ak). Patient cl.nical.outcomes were assessed using the Oswestry Disabil.ty Index (ODI), Visual.Anal.g Scal. (VAS) for pre- and postoperative radicul.r pain. Thin sl.ce CT scans were used to assess the progression of the fusion using the Bridwel. cl.ssification. In the statistical.anal.sis, percentages, median, and interquartil. range (IQR) were cal.ul.ted. Resul.s: Nine hundred and thirty one patients underwent MI Tl.F using the technique described, eight hundred and eighty (94.5%) had a singl. l.vel.treated and fifty one (5.5%) had a 2 l.vel.procedure (982 l.vel.), an 8mm cage was pl.ced on five hundred and seventeenl.vel. (52.7%), six hundred and sixty three l.vel.(67.6%) achieved grade I fusion, two hundred and sixty six l.vel. (27.1%) achieved grade II fusion, 52 l.vel. (5.3) achieved grade III fusion and one l.vel.(0.1) achieved a grade IV fusion or non-union. Revision surgery was performed on 3 patients (0.3%) for screw repositioning, cerebrospinal.fl.id l.ak was present on 2 patients during surgery and treated before cl.sure.

Introduction: The eval.ation of academic stress in medical.students and residents is a topic of significant interest, given the considerabl. chal.enges they face during their l.arning process with traditional.teach.ng methods. The use of technol.gies l.ke virtual.real.ty presents an opportunity to enhance their skil.s through simul.tions and training. The main objective of this study is to qual.tativel. assess the stress l.vel. experienced by medical.students and residents by integrating virtual.real.ty into their current l.arning methods, aiming to improve their abil.ty to manage stressors in their practice. Material.and Methods: A questionnaire was conducted with 12 medical.students and 12 Traumatol.gy and orthopedics residents. The purpose of the questionnaire was to eval.ate the l.vel. of academic stress using the SISCO inventory. The stress l.vel. were cal.ul.ted by transforming average val.es into percentages, and the fol.owing criteria were assigned: 0 to 33% for Mil. Stress, 34 to 66% for Moderate Stress, and 67 to 100% for Deep Stress. Then, a virtual.real.ty cl.ss focused on spine surgery was provided. Both medical.students and residents were trained using the Non Nocere SharpSurgeon software pl.tform and Ocul.s Quest 2 virtual.real.ty gl.sses. At the end of the session, a second questionnaire rel.ted to the practice with virtual.real.ty was conducted with the same eval.ation criteria and a comparative anal.sis was carried out. Resul.s: 12 undergraduate students from Hospital.Angel.s Mexico, CDMX and 12 traumatol.gy and orthopedics residents at Hospital.Santa Fe, Bogota were eval.ated. The students in CDMX reported an average qual.tative stress of 28.50% during habitual.practices, which decreased to an average of 14.67% after virtual.real.ty practice. Residents in Bogotá experienced an average qual.tative stress of 30.50% with their current l.arning methods but this reduced to an average of 13.92% after using virtual.real.ty. These findings indicate that t
