Admisiones y exclusiones en la práctica de la donacion de óvulos

Treballs Finals de Grau Antropologia Social i Cultural, Facultat de Geografia i Història, Universitat de Barcelona, Curs: 2013-2014, Tutor: Sílvia de ZordoEl auge de las técnicas de reproducción asistida ha generado una gran demanda de óvulos que desde el año 2009 ascendió un 80%1. Pero no todas las aspirantes podrán finalmente convertirse en donantes de óvulos. Deberán pasar un proceso de selección que admitirá a menos de la mitad de aspirantes y que finalmente donarán sus óvulos para la reproducción o para la investigación. De estas consideraciones, deriva el objetivo central de este artículo que radica en el análisis de los criterios de selección de las donantes de óvulos en las clínicas de reproducción asisti-­‐ da de Barcelona. Paralelamente, se analizan las configuraciones de las concepciones sobre la maternidad que puedan producirse tras la experiencia de la selección de donantes en las clínicas de reproducción asistida de Barcelona, y de la donación

Úlceras por presión en pacientes de un hospital de alta complejidad en Chile

Introduction. Among the reported adverse events (EA) related to Nursing Care Management are pressure ulcers (UPP). These injuries take on a special role when characterizing the most frequent events related to nursing care, both due to the increase in hospital days and the associated high economic and emotional costs. The objective of the study was to describe the characteristics of UPP in adult patients admitted to a hospital of high complexity in Chile. Material and Method. Descriptive and retrospective study. A sample of 265 patients (greater than or equal to 15 years), hospitalized in a highly complex health facility in the Ñuble region, who presented pressure ulcer(s) to reported(s) as an adverse event through an institutionally established form, was analyzed, in the period 2016-2017. Descriptive statistics and the SPSS program, version 25, were used. Results. The clinical services with the highest UPP notiication were: undifferentiated surgery (38,1%), adult critical patient unit (18,9%) and medicine (17,7%). The PU are located mainly in the sacral zone (29,4%) and heel (24,9%). The UPP average per patient is 1,3 (SD = 0,69) and is classiied mostly in stage I and II. The incidence of UPP at the hospital level was equal to 0,79% and can occur from the irst day of hospitalization. Conclusion. It is transcendental for the nursing professional to analyze this adverse event, to implement efective coping measures that contribute to improving the quality of nursing care.Introducción. Dentro de los Eventos Adversos (EA) que se reportan relacionados con la Gestión del Cuidado de Enfermería se encuentran las Úlceras Por Presión (UPP). Estas lesiones cobran un protagonismo especial al momento de caracterizar los eventos más frecuentes en relación con el cuidado enfermero, tanto por el aumento de los días de estadía hospitalaria como por los altos costos económicos y emocionales asociados. El objetivo del estudio fue describirlas características de las UPP en pacientes adultos ingresados en un hospital de alta complejidad en Chile. Material y Método. Estudio descriptivo y retrospectivo. Se analizó una muestra de 265 pacientes (mayor o igual a 15 años), hospitalizados en un establecimiento de salud de alta complejidad de la región de Ñuble, que presentaron úlcera(s) por presión notiicada(s) como EA mediante formulario establecido institucionalmente, en el periodo 2016-2017. Seutilizó estadística descriptiva y el programa SPSS versión 25. Resultados. Los servicios clínicos con mayor notiicación de UPP fueron, Cirugía Indiferenciada (38,1%), Unidad de Paciente Crítico Adulto (18,9%) y Medicina (17,7%). Las UPP se localizan principalmente en zona sacra (29,4%) y talón (24,9%). El promedio UPP por paciente es de 1,3 (DS= 0,69) y se clasifican mayoritariamente en estadio I y II. La incidencia de UPP a nivel hospitalario fue igual al 0,79% y se pueden presentar desde el primer día de hospitalización. Conclusión. Es trascendental que el profesional de enfermería analice este EA, para implementar medidas de enfrentamiento efectivas, que contribuyan en la mejora de la calidad de los cuidados enfermeros

Sex-Dimorphic Behavioral Alterations and Altered Neurogenesis in U12 Intron Splicing-Defective Zrsr1 Mutant Mice

Mutant mice with respect to the splicing factor Zrsr1 present altered spermatogenesis and infertility. To investigate whether Zrsr1 is involved in the homeostatic control that the hypothalamus exerts over reproductive functions, we first analyzed both differential gene and isoform expression and alternative splicing alterations in Zrsr1 mutant (Zrsr1mu) hypothalamus; second, we analyzed the spontaneous and social behavior of Zrsr1mu mice; and third, we analyzed adult cell proliferation and survival in the Zrsr1mu hypothalamus. The Zrsr1mu hypothalamus showed altered expression of genes and isoforms related to the glutathione metabolic process, synaptonemal complex assembly, mRNA transport, and altered splicing events involving the enrichment of U12-type intron retention (IR). Furthermore, increased IR in U12-containing genes related with the prolactin, progesterone, and gonadotropin-releasing hormone (GnRH) reproductive signaling pathway was observed. This was associated with a hyperactive phenotype in both males and females, with an anxious phenotype in females, and with increased social interaction in males, instead of the classical aggressive behavior. In addition, Zrsr1mu females but not males exhibited reduced cell proliferation in both the hypothalamus and the subventricular zone. Overall, these results suggest that Zrsr1 expression and function are relevant to organization of the hypothalamic cell network controlling behavior

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Violencia en las relaciones de noviazgo entre adolescentes de 13 a 19 años; bajo el enfoque del cuidado humano

The United Nations (UN) defines violence in dating relationships as any violent act that generates physical and psychosexual damage to the victim, including threats of death or deprivation of the autonomy that he or she has as a person, whether produced in the public or private. The objective of this research is to analyze violence in dating relationships among adolescents between 13 and 19 years old in the Casa Bonita neighborhood in southern Esmeraldas. A quantitative study with a descriptive and transversal approach was carried out, with a deductive method, in a sample made up of 20 participants who met the inclusion criteria, using a structured survey based on the violence meter and designed with the Likert scale model. The results showed that 40% of the sample were between 13 and 16 years old. Regarding the signs of violence in adolescent dating, 80% of the participants considered that these elements are fear of retaliation, family pressure, followed by 70% of adolescents who feel shame before society; 65% indicated that low self-esteem is a clear example of being a victim of violence. The signs that describe the presence of violence in adolescent dating are fear of retaliation, family pressure, shame in society, low self-esteem, emotional dependence and believe that the aggressor will change; The types of violence that frequently occur in dating relationships between adolescents between 13 and 18 years of age, with equal weight, are physical violence and psychological violence.Las Naciones Unidas (ONU), definen la violencia en las relaciones de noviazgo como todo acto violento que genere daños físicos y psicosexuales en la víctima, inclusive las amenazas de muerte o privación a la autonomía que posee como persona, ya sean producidas en el ámbito público o privado.

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
