EXPERIENCIAS ANTE EL ABORTO EN ESTUDIANTES UNIVERSITARIAS DE QUERÉTARO, MÉXICO / ABORTION EXPERIENCES IN UNIVERSITY STUDENTS

INTRODUCCIÓN. El aborto, practicado de manera clandestina, puede implicar una serie de riesgos para la madre, sobre todo si esta es menor de edad o lo realiza sin el debido monitoreo médico. OBJETIVO. Describir las experiencias de jóvenes universitarias ante el aborto, mediante la realización de entrevistas a profundidad, con la finalidad de comprender el contexto del fenómeno. METODOLOGÍA. Estudio cualitativo, fenomenológico. Se entrevistaron a 3 estudiantes, elegidas por conveniencia, que vivieron un aborto de manera autoinducida. La pregunta generadora se sometió a validación por expertos y a estudio exploratorio. Las participantes aceptaron que sus entrevistas se grabaran, previo consentimiento informado. RESULTADOS. Se obtuvieron tres categorías de análisis. 1) ¿cómo me di cuenta que estaba embarazada?; las tres participantes no fueron plenamente conscientes del hecho, sino que la sintomatología propia del estado las "alertó". 2) ¿Cómo fue el proceso para la pérdida del feto? dos de las jóvenes utilizaron medicamentos administrados por distintas vías: uno oral y otro vaginal, la tercera participante utilizó té de ruda. 3) ¿qué pasó después? A pesar de que todas deseaban que el hecho quedara oculto a sus familias, sólo una lo logró. CONCLUSIÓN. Todas las jóvenes indicaron que esta experiencia las ha marcado. Sus comentarios denotan que no han superado el fenómeno a pesar de que ya tienen varios años de haberlo vivido. Señalan que no se arrepienten de su decisión, más que procurarán que no se repita la experiencia.

INTRODUCTION. Abortion, performed clandestinely, presents a series of risks for the mother, especially if she is underage or if she performs the procedure without proper medical supervision. OBJECTIVE. To describe the abortion experiences of university women through in-depth interviews, and thereby better understand the context of the phenomenon. METHODOLOGY. Qualitative, phenomenological study. 3 university students who lived through the experience of a self-induced abortion were interviewed, and the interview questions were validated by experts and an exploratory study. The participants agreed to have their interviews recorded by providing prior informed consent. RESULTS. There were three categories of analysis: 1) ¿How did I find out I was pregnant? The three participants were not fully conscious of the fact, but the symptoms of their state "alerted" them. 2) ¿What was the process for aborting the fetus? The women had different processes; two of them used medications administered by different routes: one oral and one vaginal. The third participant used tea made from the rue plant. 3) ¿What happened next? Even though they all wanted to hide the abortion from their families, only one succeeded. CONCLUSION. All three women interviewed indicated that this experience marked them. Their comments suggest that they haven't overcome the experience even though it happened several years ago. While they do not regret their decision, they are committed to ensuring that it will never happen again.

Impact of High-Flow Nasal Cannula Use in Subjects With COVID-19 ARDS at High Altitudes: Clinical Presentation and Prognostic Factors.

BACKGROUND: High-flow nasal cannula (HFNC) reduces the need for intubation in adult subject with acute respiratory failure. Changes in hypobaric hypoxemia have not been studied for subject with an HFNC in ICUs at altitudes > 2,600 m above sea level. In this study, we investigated the efficacy of HFNC treatment in subjects with COVID-19 at high altitudes. We hypothesized that progressive hypoxemia and the increase in breathing frequency associated with COVID-19 in high altitudes affect the success of HFNC therapy and may also influence the performance of the traditionally used predictors of success and failure. METHODS: This was a prospective cohort study of subjects >18 y with a confirmed diagnosis of COVID-19-induced ARDS requiring HFNC who were admitted to the ICU. Subjects were followed up during the 28 d of HFNC treatment or until failure. RESULTS: One hundred and eight subjects were enrolled. At admission to the ICU, FIO2 delivery between 0.5-0.8 (odds ratio 0.38 [95% CI 0.17-0.84]) was associated with a better response to HFNC therapy than oxygen delivery on admission between 0.8-1.0 (odds ratio 3.58 [95% CI 1.56-8.22]). This relationship continued during follow-ups at 2, 6, 12, and 24 h, with a progressive increase in the risk of failure (odds ratio 24 h 13.99 [95% CI 4.32-45.26]). A new cutoff for the ratio of oxygen saturation (ROX) index (ROX ≥ 4.88) after 24 h of HFNC administration was demonstrated to be the best predictor of success (odds ratio 11.0 [95% CI 3.3-47.0]). CONCLUSIONS: High-altitude subjects treated with HFNC for COVID-19 showed a high risk of respiratory failure and progressive hypoxemia when FIO2 requirements were > 0.8 after 24 h of treatment. In these subjects, personalized management should include continuous monitoring of individual clinical conditions (such as oxygenation indices, with cutoffs adapted to those corresponding to high-altitude cities).

Tolerance to cadmium of Agave lechuguilla (Agavaceae) seeds and seedlings from sites contaminated with heavy metals.

We investigated if seeds of Agave lechuguilla from contaminated sites with heavy metals were more tolerant to Cd ions than seeds from noncontaminated sites. Seeds from a highly contaminated site (Villa de la Paz) and from a noncontaminated site (Villa de Zaragoza) were evaluated. We tested the effect of Cd concentrations on several ecophysiological, morphological, genetical, and anatomical responses. Seed viability, seed germination, seedling biomass, and radicle length were higher for the non-polluted site than for the contaminated one. The leaves of seedlings from the contaminated place had more cadmium and showed peaks attributed to chemical functional groups such as amines, amides, carboxyl, and alkenes that tended to disappear due to increasing the concentration of cadmium than those from Villa de Zaragoza. Malformed cells in the parenchyma surrounding the vascular bundles were found in seedlings grown with Cd from both sites. The leaves from the contaminated place showed a higher metallothioneins expression in seedlings from the control group than that of seedlings at different Cd concentrations. Most of our results fitted into the hypothesis that plants from metal-contaminated places do not tolerate more pollution, because of the accumulative effect that cadmium might have on them.

Grado de conocimiento de los pacientes que se realizan autocateterismo vesical intermitente / Level of knowledge of patients that practice intermitent vesical selfcatheterization

El autocateterismo vesical intermitente posee múltiples ventajas en relación al uso de sonda vesical a permanencia, y en el último tiempo ha tenido mayor aceptación en la instituciones de salud en que se atiende a pacientes con Traumatismo Raquimedular, principal causa del uso de esta técnica. Por lo tanto, es importante conocer cuánto saben los pacientes del ACVI, así como la forma en que lo realizan, a fin de poder mejorar el manejo de ellos. La información se obtuvo de una encuesta de 30 pacientes institucionalizados (60% del Hospital de la Mutual de Seguridad y 40% del Hospital del Trabajador), de sexo masculino. Se pudo apreciar que la mayoría de los usuarios de ACVI manejan adecuadamente la técnica, lo que es bueno desde el punto de vista del auto-cuidado, ya que se previenen complicaciones. El 77% de los usuarios manifestó que fue capacitado por la enfemera, a quién le corresponde dicha capacitación, por encontrarse la técnica dentro de su campo de acción. Otros factores que influyen con la forma de realización de la técnica son el tiempo de uso y el estado civil. el 70% de los usuarios de ACVI encuestados manifestó que el ACVI facilita el desarrollo de su vida, tanto en el aspecto laboral y social como en su vida de pareja. Dados estos resultados, debería haber un control estadístico inserto en un programa para pacientes usuarios de ACVI que contemple la participación de un equipo de salud multidisciplinario y grupos de auto-ayuda
