Cigarette smoking affects uterine receptiveness
2006
Background Cigarette smoking has long been known to have an effect on female fertility. The existence of an ovarian factor is clear when one considers that the mean age of the menopause is lower and IVF cycle outcome is worse in heavy smokers. The hypothesis of a concomitant uterine effect is raised by indirect evidence from in vitro and in vivo studies, but as yet, no direct evidence has been gained to confirm its existence. In this work, we analyse the association between smoking habit in oocyte recipients and cycle outcome. Methods We have retrospectively analysed the outcome of all oocyte donation cycles performed in our clinic from January 2002 to June 2005 from which there was availab…
Closed vs. Open Oocyte Vitrification Methods Are Equally Effective for Blastocyst Embryo Transfers: Prospective Study from a Sibling Oocyte Donation …
2020
<b><i>Purpose:</i></b> To assess whether open and closed vitrification protocols are equally effective for sibling-oocyte cycles when performing blastocyst embryo transfers. <b><i>Materials and Methods:</i></b> A prospective study was set up comparing the open and the closed vitrification techniques in oocyte recipients sharing sibling oocytes between 2014 and 2016. Sibling oocytes were randomly and equally assigned into the closed group (oocytes vitrified in a closed system) or the open group (oocytes vitrified in an open system). Intracytoplasmic sperm injection was performed on all cases. Embryo transfers were performed on day 5. Power anal…
Natura e caratteristiche del consenso al prelievo di organi e tessuti da cadavere Un raffronto tra Italia ed Inghilterra
2018
The essay deals with the deceased donor organ donations and, in particular, with the nature and the features of the consent which authorizes the removal from the body of a deceased person of any relevant material. The analysis is conducted through the scrutiny of the relationship that exists between the choice about to be or not an organ donor and the social interest to obtain a rapid increase of organ donation. The essay makes a comparison between the Italian and the English legal approaches to the freedom of deciding the allocations of removed organs, with a special regard to directed donations.
Cumulative newborn rates increase with the total number of transferred embryos according to an analysis of 15,792 ovum donation cycles
2011
Objective To measure the success of in vitro fertilization (IVF) of donated ova according to cumulative newborn rates (CNBR) per number of embryos required to achieve at least one newborn (EmbR), considering in addition the relevance of age and infertility etiology. Design Survival curves and Kaplan-Meier methods were employed to analyze CNBR with respect to the number of EmbR in a retrospective cohort of oocyte donation recipients. Setting University-affiliated infertility center. Patient(s) Infertile couples undergoing IVF with oocyte donation. Intervention(s) None. Main Outcome Measure(s) CNBR per EmbR. Result(s) The CNBR increased radically (up to 64.8%) between 1 and 5 EmbR, moderately…
Organ transplantation in China: concerns remain
2015
On Dec 3, 2014, Jiefu Huang, Director of the China Organ Donation and Transplant Committee and former Vice Minister of Health, announced that, from Jan 1, 2015, only voluntarily donated organs would be used for transplantation. Worldwide media reported that China would stop use of executed prisoners as an organ source. The Editorial1 in The Lancet interpreted the announcement in a similar manner; unfortunately, this interpretation does not reflect the reality.
Egg donation, surrogate mothering, and cloning: attitudes of men and women in Germany based on a representative survey
2009
Objective To determine opinions and attitudes of the German general population toward the treatment methods of reproductive medicine: egg donation, surrogate mothering, and reproductive cloning. Design Representative survey. Setting German general population: face-to-face interviews at home with 2,110 persons, aged 18–50 years. Patient(s) Patients were not included. Intervention(s) No interventions took place. Main Outcome Measure(s) Approval and disapproval of treatment methods of reproductive medicine and preimplantation genetic diagnosis were assessed by questionnaires regarding medical, age, reasons, or general. Result(s) Overall, the diverse treatment methods of reproductive medicine f…
Similar morphokinetic patterns in embryos derived from obese and normoweight infertile women: a time-lapse study.
2013
Study question Does female obesity affect the dynamic parameters of embryo quality assessed by time-lapse analysis? Summary answer Female obesity does not affect the dynamic embryo quality as determined by image acquisition and time-lapse analysis. What is known already Female obesity impairs natural and assisted reproduction but there is no agreement on the specific contribution of gametes, embryos or endometrial receptivity. In this preliminary study the dynamic parameters of embryo quality are assessed for the first time by time-lapse analysis. Study design, size, duration Two-year cohort retrospective study comparing embryos from three groups of patients according to the presence of inf…
Omosessualità ed esclusione sociale nella donazione di sangue: divieti permanenti e divieti temporanei come fattore di discriminazione
2016
Around the world, as a consequence of the contamination of the blood supply by HIV and Hepatitis C and B in the early 1980s, public and private blood banks have required blood donors to complete a donor health assessment questionnaire to identify various risk factors for sexually transmitted diseases including, for men, the act of having sex with a male partner. In this latter case the policy provides for a permanent or temporary ban on donation. This deferral policy, which aimed to protect recipients of blood and blood products, in recent years has been subject to criticism in so far as this exclusion seems to be an unfair discrimination against gay men on the basis of sexual orientation. …
Food Assistance
2018
Food assistance and food charity refer to practices where public, private, or third sector actors provide food (or resources to acquire food) to individuals or households that face hunger or food shortage. The food is provided for free or for a minimal cost and the provision is conducted through varying services like food banks. Domestic food assistance practices are realized in relations between a collective (the provider or donor) and individuals (the recipients of the assistance). For those international practices of food aid that take place between collectives, typically nations or global food aid organizations and recipient countries, see the entry for Food aid. Currently, approximatel…
Support for culture via crowdfunding in question: beyond motivations, an analysis of the barriers to participate
2017
In a context of strong budgetary pressure for non-market cultural organizations and of relative slowdown of crowdfunding campaigns in this sector, this reflection aims to provide a critical analysis of these new forms of financial support for culture. After drawing up a state of the art on the levers and obstacles to participation in such financing operations, the results of a qualitative study based on 43 individuals (donors and non-donors, familiar or not with cultural practices) will be exposed to highlight the diversity of misgivings about crowdfunding, beyond the traditional barriers attached to cultural gift, and the paradoxes that these calls for generosity arouse.
