Dialysis conference link
Hi thanks for some good additional material on peritoneal dialysis. I have though removed the external links to the Nephrology conference. Wikipedia is not a directories listings, nor a collection of external links, if it were then every conference on every subject would seek to insert its link into all possible articles on wikipedia. The conference website was I think a poor external link for wikipedia as:
 * Access to the actual material is not open and seems to require some form of registration. (hence articles citing papers from a journal often include a link to the freely accessible PubMed abstract, but direct url links to the journals' article is not done if this requires subscription to the journal).
 * Much of the conference talks are off-topic for encyclopaedia readers (e.g. for the day on peritoneal dialysis, I see some of the talks were on how to set up such a PD service - of importance to a Nephrologist but not to general readership or indeed really for dialysis patients)
 * Similarly we don't have for dialysis topics links to Journal of Urology homepages. Instead if there is a particular presentation that might be useful (e.g. a revised simpler & safer description of home peritoneal dialysis for patients to follow, then a direct link would be more appropriate.)
 * Finally adding the link to multiple pages might seem like spamming – see WP:SPAM point 5) Don't gratuitously set off our spam radar.  re "Adding the same link to many articles", for which I seem to be acting as that "itchy trigger finger on the revert button" – sorry :-) David Ruben Talk 01:50, 8 January 2007 (UTC)

Ultrafiltration and Hemodialysis
Hi, Jtdaugir-I've discussed what i think about the ultrafiltration edit on the hemodialysis talk page, here which is probably the best place to discuss edits. See you later!Felix-felix 09:46, 15 January 2007 (UTC)

Welcome, WP:COI, WP:CLINMED, WP:Nephro, Referencing
Thank you for your contributions. I hope you like the place and decide to stay.

Based on your user name, I have the impression you're John T. Daugirdas. If this is so, I'd like you to be aware of Conflict of interest, as you're adding references to yourself.

I reverted the collection of books you added in dialysis.{my revert} WP is not a respository of links/a list of books to read-- WP:NOT. IMHO, a list of books is not that useful-- it is better to supply external links (WP:EL)--whereas WP is NOT a list of links either. Generally, it is much better to add content-- something that explains, i.e. some information and to source it properly (WP:REF).

On the topic of referencing, here is a link that explains it in detail-- for medical articles: WP:CLINMED/Writing_medical_articles.

We have a place where the medically minded people hang out: WikiProject "Clinical Medicine". You are invited to join or just browse the talk page, which is also known as the doctors' mess. There is also a project devoted to things nephrology -- WikiProject Nephrology or WP:RENAL (the shortcut). Things are a bit slow there, but it is the place for discussing bigger edits across nephrology/nephrology-related articles.

I hope you enjoy editing here and being a Wikipedian! If you have any questions feel free to leave me a message on my talk page. Again, welcome! Nephron T|C 07:06, 28 January 2007 (UTC)


 * I've just noticed the above edit by Nephron. Whilst what he says is true, I hope you're not avoiding referencing any of your work solely on this basis. We're all big and ugly enough to chop stuff out if we think it's dodgy, and your work in this field is notable.  Felix Felix talk 08:00, 14 April 2007 (UTC)

Beta-2-Microglobulin
This is a good para, but would be much more appropriate in the hemodialysis article, wouldn't you say? The citations all refer to high flux HD. Unless you've any objections, I'll cut and paste it over to the hemodialysis article.Felix-felix 08:25, 8 February 2007 (UTC)

Well, it's a continuum. B2-M clearance is about 20-80 with high-flux HD, and then can go from 80-160 or more with IHDF. There is the whole issue of hemodialysis membranes as well. Really, this is an issue of dialysis adequacy. I don't care where you put the para, Felix. As the wiki evolves, the optimal placement will become more clear.

John T Daugirdas
Are you really one and the same? I'm mightily impressed, I bought your handbook of dialysis many moons ago-and still feel in awe everytime I pick it up! Hope you think my edits weren't too stupid...  Felix Felix talk 20:34, 11 February 2007 (UTC)

Renal Tubular Acidosis
If you have a spare moment, could you take a look at renal tubular acidosis, which I've been polishing for a while, and am trying to get to Good or even featured article status. So I'm after opinions, and I'd appreciate yours!  Felix Felix talk 08:14, 14 April 2007 (UTC)

Sure, but I'm not sure how to do this or where to write the opinions (John).

Standardized Kt/V
In response to : "C-infinity" is the steady state concentration; it is simply the solution of C at time infinity, i.e. when the transient has fully dissipated. It represents continuous dialysis, i.e. dialysis 24/7.

>The first is to develop a measure of clearance that is independent of the frequency of treatments, which is similar to creatinine clearance and UV/P, which translatest to g/time-averaged concentration, or Ctac (is this C-infinity?). This was developed by Casino and Lopez. The other concept is why this was modified by Gotch to use the C(mean predialysis) and not Ctac.

There are a number of way one could create a measure independent of frequency. Standardized Kt/V, formost, is a normalized concentration IMHO. You can add a ref for Casino and Lopez. Personally, I don't think it is so important -- C TAC wasn't so much developed -- as it was there (mass transfer was modeled before renal dialysis existed). It is as intuitive as RMS voltage, to an electrical engineer.

>It is not C0, but the average of the C0 values for each dialysis treatment.

Gotch does his calculations based on equally spaced dialysis and I focused on this. If you have a good reference for unequally spaced dialysis, it would be a valuable addition.

>I think I could try to explain this without a lot of the math, which I think just confuses people, but I suspect that you put this up and didn't want to "erase" your work.

If one understands the math it is easier to understand and much more compact.

That said, a wordy explanation (directed at people that are math challenged) would be a valuable addition. Nephron T|C 12:15, 28 July 2008 (UTC)
