Failures (with some successes) of assisted reproduction and gamete donation programs
2013
Although the possibilities for the treatment of infertility have been improved tremendously, not every couple will be treated successfully.Crude overall pregnancy rates of 50-65% per patient can be achieved nowadays, irrespective of the type of profertility treatment applied first.IVF only accounts for about 20% of the pregnancies achieved. Dropout is an important reason for not reaching the estimated pregnancy rate. Even after failed IVF, spontaneous pregnancies do occur. Sperm and oocyte donation (OD) offer additional chances to subfertile couples. Severity of the male factor (in sperm donation) and young donor age (in OD) are important determinants of success.Analysis of assisted reprodu…
The significance of premature luteinization in an oocyte-donation programme
2006
BACKGROUND: Several evidences indicate that premature luteinization (PL) may affect IVF outcome. The primary end-point of the present study was to verify the effect of PL on the pregnancy rate (PR) of our oocytedonation programme. METHODS: PL was defined as serum progesterone ³1.2 ng/ml on the day of HCG. We analysed retrospectively 240 oocyte-donation cycles in which 120 women donated twice, with PL in the first donation cycle and no PL in the following one, acting as its own control. Recipients (n = 240) were divided in two groups according to the presence of PL (n = 120) or not (n = 120). Both groups were compared regarding donor cycle parameters and recipient cycle outcome. RESULTS: The…
Pure donation or hybrid donation crowdfunding
2019
PurposeDespite the growing research exploring the possibility and feasibility of financing socially oriented projects through crowdfunding, relatively little research examines which crowdfunding model is better to serve such purpose. The purpose of this paper is to offer novel insights to mitigate this research gap.Design/methodology/approachA unique data set collected from the largest Chinese crowdfunding platform is used to test the hypotheses. To solve the perceived self-selection problem, the propensity score matching method is adopted in this paper. Based on this approach, the results of similar prosocial campaigns in two different models (pure donation and hybrid donation) are compare…
Crowdfunding success: a systematic literature review 2010–2017
2020
PurposeThe paper takes stock of accumulated knowledge on factors impacting the success of online crowdfunding (CF) campaigns while suggesting opportunities for future research development.Design/methodology/approachA Systematic Literature Review of 88 academic papers published between 2010 and 2017. Papers were collected from four academic databases and published in 65 different journals. The review addresses issues related to theory, methods, context, findings and gaps. Overall, the paper presents an analysis of 1,718 associations between 111 aggregated independent variables (from 927 variables) with six main aggregated success indicators.FindingsMost research involves quantitative analyse…
Importancia de la integración e implementación de un Modelo de Gestión de Medicamentos en programas de Cooperación Internacional
2020
La gestión de los medicamentoscontinúa siendo un reto en la mayoría de los paísesen vías de desarrollo, dónde no existen sistemasde gestión que garanticen la calidad/disponibilidadde los medicamentos, lo cual implica un grave impacto en la salud de la población atendida.Es por ello muy importantedisponer de unModelo de Gestión de Medicamentos. Este modelo esundocumento que sirve como referencia para organizar el trabajo en torno a los medicamentos y cubre todos los pasos involucrados en la gestión de los mismos; desde su compra hasta la utilización por parte del pacientey en su caso,suposterior eliminación regulada.Los documentos,protocolos y guíasque serán parte de este modelo estarán siem…

The type of GnRH analogue used during controlled ovarian stimulation influences early embryo developmental kinetics: a time-lapse study
2013
OBJECTIVE: To explore if the GnRH analogue used for controlled ovarian stimulation (COS) and the ovulation triggering factor (GnRH agonist + hCG triggering versus GnRH antagonist + GnRH agonist triggering) affect embryo development and kinetics.STUDY DESIGN: In a retrospective cohort study in the Instituto Valenciano de Infertilidad (IVI) Alicante and the Instituto Universitario-IVI Valencia, Spain, 2817 embryos deriving from 400 couples undergoing oocyte donation were analysed. After controlled ovarian stimulation and IVF/intracytoplamic sperm injection, the timing of embryonic cleavages was assessed by a video time-lapse system. The results were analysed using Student's t test for compari…
Los contratos en materia de reproducción humana asistida: especial tratamiento de la autonomía de la voluntad en las donaciones de gametos y en el de…
2022
RESUMEN: A pesar de que en nuestro país la autonomía privada preside la regulación principal en materia de contratos, ésta se encuentra ampliamente condicionada a la hora de suscribir acuerdos en materia de reproducción humana asistida. En consecuencia, es la Ley 14/2006, de 26 de mayo, la que establece ineludiblemente las pautas y requisitos que deben cumplir las partes intervinientes. De esta forma, las donaciones de gametos llevadas a cabo en nuestro país, o la toma de decisión sobre el destino que habrá de darse a los embriones crioconservados, están absolutamente marcados por la ley, dejando un escaso margen de actuación a las clínicas y usuarias que participan en estas prácticas. Por …
Willingness to Donate Organs After Death
2023
Abstract: Background: Despite the growing number of organ transplants, there is still a significant difference between the number of donated organs and the number of people waiting for them. Knowing the reason people decide to donate is the first step to increasing organ donation rates. Aims: The main aim of the present study was to develop and validate a new scale for organ donation. Method: In three studies, 3,585 participants ranging in age between 14 and 89 years were selected through systematic random sampling. In the first study, we created a scale following the organ donation model theoretical framework and submitted the scale to exploratory factor analysis. In the second study, we …
Filosofías del don: Usos y abusos de la donación en la ética contemporánea
2013
El objetivo de este artículo es analizar el concepto de donación en la ética contemporánea. Este análisis se realiza en tres momentos: el primero se sitúa en la introducción y muestra que es un concepto importante en el que convergen la fenomenología, el personalismo y la hermenéutica. Esta convergencia no solo supone un uso frecuente del concepto sino un abuso del mismo cuando se construye de espalda a las mediaciones objetivas o institucionales que lo condicionan. El segundo presenta una antropología del don y muestra su relación con los objetos, la reciprocidad, la deuda y la libertad. En el tercer momento se describe la filosofía de la donación de Paul Ricoeur, donde se comprueba un uso…
