The concept of fast freezing or vitrification was first described more than 80 years ago by Basile J. Luyet, the so-called Father of Cryobiology (Luyet, 1937). He showed that supercooled solutions could be solidified without crystallization, forming a glass-like state. Already then, the potential of the technique and the associated challenges were in the research spotlight. Today, we’ve managed to overcome all methodological-related issues of vitrification. It has evolved into a reliable and efficient method to freeze oocytes and embryos. Vitrification is used for medically assisted reproduction and fertility preservation: the goal is to ensure the maximum survival rate with the highest level of biosafety. In this blog post, we will compare closed and open carrier devices for vitrification.
Why there is a need for the sustainable development goals
The establishment in 2015 of the Sustainable Development Goals (SDGs) has created a global consensus on the development framework for a better world. However, as we look to the next decade, there is significant cause for concern about the future. The IPCC’s Sixth Assessment report, released in August 2021, confirms that it is indisputable that human influence has warmed the climate system, raising global surface temperature. The report confirms that there is no going back from some changes that are already affecting the climate system. These changes in the climate are widespread, rapid and intensifying and impacts are affecting every region on Earth, including the oceans.
Introduction to Medical Device Regulations - MDR
For 30 years medical devices have been governed by the Medical Device Directive (MDD) implemented in EU/EEA in 1993, and there have been quite a few developments in the field of medical devices since then. For instance, apps used as stand-alone products for different medical purposes have become a reality. The general population has become older, patients are more used to finding medical information on the internet, and the beauty industry uses more advanced and invasive techniques than before. These changes, and more, have prompted an update of the control of medical devices for some time. Eventually, the new Medical Device Regulations (MDR) were developed and came into force on May 26, 2021. From this date, all new medical devices and the manufacturer’s quality management system must comply with the MDR. Implementation deadlines for existing devices are dependent on classification and expiry of existing MDD certificates.
The use of time-lapse technology in IVF has in many parts of the world become a standard of care. The benefits are many, including the ability to communicate with patients about their treatments. A recent study aimed to find out how the patients value to view time-lapse sequences of their embryos at the time of embryo transfer.
Why a blog? Our world today is on-line. We see this as an opportunity of fast and transparent communication and believe a blog is a unique way of sharing our knowledge, experience and to create a dialogue. A blog post is a perfect format for topics to be discussed, analysed and shared. We have a great deal that we would like to share with you, and we also look forward to you sharing your knowledge with us.
