April 2011 Slightly revised version of AIDA v4.3b released which addresses some minor technical issues with the software.

January 2011 AIDADEMO v1.2 launched. AIDADEMO v1.2 is a minor upgrade which tidies certain aspects of the DOSBox AIDADEMO environment. AIDADEMO v1.2 also includes a standard Windows uninstall routine. This latest version of the AIDADEMO program is available without charge by clicking here.

August 2010 AIDADEMO v1.1 launched. AIDADEMO is a freeware demonstration version of the AIDA program which shows what AIDA can do. AIDADEMO v1.1 is a technical upgrade which uses a new, improved, open source Windows install procedure - and makes use of DOSBox, a free, open source environment which helps to keep the AIDADEMO program working on Windows Vista and Windows 7 PCs.

April 2010 AIDA v4.3b launched. AIDA v4.3b is a technical upgrade which uses a new, improved, open source Windows install procedure - and makes use of DOSBox, a free, open source environment which helps to address some AIDA v4 display problems on notebook PCs, and computers running Windows Vista. AIDA v4.3b also includes a standard Windows uninstall routine, and incorporates other minor technical updates to facilitate further developments.

Up to the launch of AIDA v4.3b - the AIDA Websites logged over 2 million visits, over 347,500 downloads, and over 510,000 on-line diabetes simulations - since AIDA was first released on the internet. Full logstats available by clicking here.

January 2009 A further research article arising out of the collaborative venture to incorporate a generic model of subcutaneous insulin absorption into AIDA is published in the medical / diabetes literature. The article reporting on: Incorporating a Generic Model of Subcutaneous Insulin Absorption into the AIDA v4 Diabetes Simulator. 3. Early Plasma Insulin Determinations is available via this link.

2008 AIDA Websites log over 1.6 million visits, over 300,000 downloads, and over 450,000 on-line diabetes simulations since AIDA was released on the internet. Full logstats available by clicking here.

The articles reporting the collaborative development plan, and the initial bench testing can be found by clicking on these links.

2006 - 2007 Results of a survey of 200 users of the AIDA v4 diabetes simulator are published in the medical / diabetes literature. The articles reporting the analysis of the quantitative data, qualitative data, and discussing the findings can be found by clicking on these links.

2005 AIDA Websites log over 660,000 visits, over 190,000 downloads, and over 325,000 on-line diabetes simulations since AIDA was released on the internet. Full logstats available by clicking here.

November 2005 AIDA Diabetes / Insulin Tutorial - which teaches a bit about balancing insulin and diet in diabetes using the interactive AIDA on-line diabetes simulator to illustrate educational points - gets its own dedicated web address (URL) at http://www.2aida.info.

January 2004 Results of a British Diabetic Association (BDA) assessment of AIDA v4 are published in the medical / diabetes literature. The BDA has since been renamed "Diabetes UK". The article reporting the results is available by clicking here.

January 2003 First results from a prospective randomised-controlled pilot study for evaluating the teaching utility of AIDA are published in the medical / diabetes literature. The article reporting the results is available by clicking here.

July 2002 AIDA US Mirror Site moved to a new, larger, faster facility with considerably greater bandwidth in California, USA at http://www.2aida.net.

This US Mirror Site will continue to serve (North) American visitors, and will also hopefully - being on the West Coast of the United States - provide faster access to the AIDA site for Far Eastern / Australasian visitors.

Due to continuing (and increasing) demand at the AIDA Website, visitors to the UK / European site may find themselves re-directed to the US Mirror Site. However for the time being all 'AIDA on-line' Web-based diabetes simulations will continue to be run from the UK / European site - with all downloads (of software and journal articles [PDF files]) taking place via the US site.

It is intended that longer term this new US Mirror Site should offer considerably more bandwidth, plus room for expansion of the AIDA Website, as interest in the diabetes simulation approach continues to grow.

October 2001 The first four sections of a new Diabetes / Insulin Tutorial go 'live' at the AIDA Website. This Web-based tutorial aims to teach a little bit about balancing insulin and diet in diabetes, as well as offering some information about different insulin-dosage adjustment regimens.

However this tutorial aims to be different by combining purely static / informational Web pages with a more dynamic Web-based diabetes simulator to allow interactive educational simulations to be performed of clinically relevant diabetes situations. Therefore, while reading about, say, "conventional insulin therapy" it is possible to click on an HTML link and see some examples of such therapeutic regimens being simulated.

We hope this approach will provide a more integrated (and fun) way for people to learn some more about the 'roller coaster' ride that can be diabetes. We also expect that combining static / informational Web-based resources with 'AIDA on-line' will offer a more intelligent way of making use of what the on-line diabetes simulator can offer.

The first four sections (chapters) of the Diabetes / Insulin Tutorial cover: "Insulin-dosage adjustment (basics)", "Choosing the insulin dose", "Timing of meals and diet planning", and "Glucose and the kidney". Further sections are planned to be added in due course on "Rapidly-acting insulins & insulin pumps" and the "Pathophysiology of diabetes".

September 2001 'AIDA on-line2' (version 2) became available for general use. This updated version of the Web-based diabetes simulator incorporates glycosylated haemoglobin (HbA1c) levels for the on-line diabetes simulations. This means that for each simulation an expected / predicted HbA1c estimate is provided - based on the assumption that the simulated blood glucose control might be maintained for a 2-3 month period. As with everything else with AIDA, the HbA1c model incorporated within 'AIDA on-line2' is only intended for educational / self-learning / demonstration purposes. Nevertheless this should still be a useful addition to the facilities offered by the Web-based diabetes simulator.

'AIDA on-line2' also now includes user definable limits or boundaries for the diabetes simulations. These can be turned on or off, as required, and the actual levels can be adjusted to suite personal preferences. The intention of these limits / bounds is to provide a target for visitors / users - to aim for when trying to improve the simulated blood glucose profile.

Further, minor, tidy up improvements have also been made to 'AIDA on-line' to enhance people's usage of the Web-based diabetes simulator. To check out 'AIDA on-line2' (version 2) - please visit http://www.2aida.org/online at this site.

August 2001 Two new slightly updated versions of the AIDA PC software were released after a short period of beta-testing. AIDA v4.3a is the recommended latest version of the program. This builds on the benefits of AIDA v4.3 (see below), but trials a new, faster Windows install procedure. With this upgrade a number of URLs and email addresses in the program which were becoming out of date have also been updated, ensuring closer links between the AIDA PC software and this Website.

An identical updated version of the program, but using a DOS installation procedure, has also been released. This is called AIDA v4.1a and replaces the previous DOS-installation release (AIDA v4.0). AIDA v4.1a incorporates all the benefits of AIDA v4.3 (see below) - and AIDA v4.3a - but allows people with 16-bit DOS or Windows (v3.1 / v3.11) operating systems to continue making use of the downloadable diabetes simulator.

Both AIDA v4.3a and AIDA v4.1a can be downloaded without charge from the AIDA Download Web page.

Please note: If you have an older version of PC AIDA installed on your hard disk, which you are still using, you may wish to make a backup copy of your DATABASE.FIL clinical case scenario database file. This can be found in your AIDA PC directory. If you do not back this up - and then restore it to your AIDA PC directory after installing the new version - you may run the risk of losing all of your own specially created case scenarios if you try and install AIDA v4.3a (or AIDA v4.1a) into your existing AIDA PC directory.

July 2001 A US Mirror Site for the AIDA Website has been commissioned. This is hosted from Baltimore, Maryland, U.S.A. and provides (North) American AIDA users with a site much closer to home. The main AIDA Website (www.2aida.org) continues to be hosted from a major Internet hub / centre in London, England offering European AIDA users with a fast local site.

However a large proportion of AIDA and 'AIDA on-line' users come from the U.S.A. and Canada. Therefore having a dedicated US Mirror Site makes sense and should ensure continued fast Website response times for site visitors from North America. In addition having a mirror site located on a separate continent provides a useful (and reassuring) form of site backup! Indeed if one site were to 'go down' the other should still remain functioning as normal. Furthermore having a mirror site offers AIDA increased bandwidth which will become of increasing importance as newer versions of the freeware software are released. Also having a mirror site offers AIDA a considerable amount of flexibility in how file downloads are coordinated. For the time being all AIDA software / demo program and PDF (article) file downloads are being handled by the US AIDA server.

Please note: the URL to quote for all access to the AIDA Website remains http://www.2aida.org (and http://www.2aida.org/online for 'AIDA on-line'). Site visitors can access the US Mirror site (or switch back to the European site from the US site) via a link on the right of the AIDA Home Page.

February 2001 'AIDA on-line' Web-based diabetes simulator moved here to the main AIDA Website. 'AIDA on-line' can now be accessed directly at: http://www.2aida.org/online

This new on-line simulation facility takes advantage of a faster 650 MHz Pentium III server and also utilises smaller file sizes for the graphical simulation files (30%-80% smaller than before). As a result the Web-based simulations should be generated quicker than before, and they should be faster to download / transfer via the Internet. For visitors with older Web browsers (e.g. Netscape Navigator v3, Internet Explorer v3, or before) which are unable to display these newer, smaller simulation graphs - a slightly slower version of 'AIDA on-line' is also available (via the same links). This renders the diabetes simulation graphs in .jpg format which although larger (and therefore slower to load) can be viewed even with less modern browsers.

October 2000 The AIDA Website moved to its own dedicated URL (http://www.2aida.org) with its own dedicated Webspace and cgi-bin. Long-term this should facilitate further developments/enhancements to AIDA.

July 2000 A new version of the PC AIDA software (called AIDA v4.3) was released. This contained a number of technical enhancements / upgrades - including: (1) a streamlined (hopefully simplified) Windows-based (32-bit) installation procedure; (2) default maximum setting of 'Environment Space' for 32-bit operating systems; (3) a 'fix' for AIDA usage on fast Pentium II / III PCs; (4) hot key by-passing of introductory caveat screens (much requested); (5) reduced install file size (1.0Mb instead of 1.5Mb) - so download will be faster and will now fit on a single floppy diskette; (6) simplified method for user registration; (7) import / export facility to allow case scenarios to be swapped between users via email / the Internet; (8) HbA1c calculator - assuming simulated blood glucose profile was typical for 2-3 months; and (9) other minor 'tidy up' updates.

AIDA v4.0 remains available for download for DOS / Windows '3.1 / '3.11 users with 16-bit operating systems.

October 1999 Due to continuing interest in the AIDA diabetes simulation approach - a new AIDA registration / announcement list was setup. This replaced all other methods of registering an interest in AIDA. The list is open to anyone who wants to subscribe but no one, other than AIDA's developers, are able to post to the list. This list is intended to help us (the developers) keep you (the users) informed of future upgrades and enhancements to the system. The idea is that as interest in AIDA and 'AIDA on-line' continues to grow - there should be no manual work required to keep track of who has registered - and therefore keep you informed about further developments with the simulator. It is envisaged that very few messages will actually be posted via this list. However in the coming months we expect there to be some information regarding AIDA about which you might wish to be informed (e.g. a new version of 'AIDA on-line', and a long-awaited update to the PC version of the AIDA diabetes simulator). If you wish to automatically receive these announcements by email - please subscribe to this list. It goes without saying - but perhaps it should be confirmed - that no email details will be made available to any third parties. Please enter your email id below to join the AIDA diabetes simulator registration / announcement list.

Alternatively if you find the list subscription service slow or busy - you can also subscribe to the AIDA registration / announcement list at any time, directly, by sending a blank email note to subscribe@2aida.org

August 1998 Following 8 months of beta-testing 'AIDA on-line' was formally launched. This provides AIDA's interactive educational diabetes simulations in a Web browser window. No downloads or installation are needed. As a result the simulations can be accessed from any computer (PC, Apple Mac, Linux, Unix server, etc) from anywhere in the world - provided the computer has access to the Internet. An advantage of this Web-based approach is that any enhancements or modifications to the system immediately become available worldwide - via the Web. To check out 'AIDA on-line' click on the On-line Simulation link on the left frames bar.

January 1997 A slightly revised version of PC AIDA was uploaded on 17th January 1997. Please note this is still called AIDA v4.0. If you have an older version of PC AIDA installed on your hard disk you may wish to make a backup copy of your DATABASE.FIL clinical case scenario database file. This can be found in your AIDA PC directory. If you do not back this up - and then restore it to your AIDA PC directory after installing the new version - you will lose all of your own specially created case scenarios.

June 1996 AIDA v4.0 goes 'live' on the Internet - made available for general release as freeware software. The program can be downloaded without charge from this site.

March / April 1996 AIDA v3.8 / v4.0 PC program first made available for beta testing by email and on the Web. Software formally tested by approximately 60 patients and medical users (all with Internet access). As a result of their feedback further refinements were made to the system - particularly related to technical issues to help ensure that the software would run on as wide a variety of PC hardware as possible.

1994 - 1996 AIDA v2.3 made available without charge on diskette to researchers in the diabetes computing field. Copies shipped from London worldwide, by Air Mail, so that research colleagues could try out a prototype version of the AIDA diabetes simulator.

1991 First AIDA-related publications appear in the scientific literature overviewing the model of glucose-insulin interaction employed in the AIDA diabetes simulator. The two conference proceeding reports A Physiological Model of Glucose-Insulin Interaction and A Clinical Model of Glucose-Insulin Interaction are available on line by clicking on these links.

Early 1990s Initial compartmental, physiological model of glucose-insulin interaction in insulin-dependent (type 1) diabetes designed - and first Mk. I prototype version of the AIDA diabetes simulator developed - programmed in Turbo Pascal.
