International Pi Day and taking a Pie to the Face for Kidney Disease

So Pi Day is just about over but during the day we did a three stooges around the Topf household. After taking the pie to the kisser I wrote a check to the National Kidney Foundation of Michigan for $31.41.

I'd like to challenge Matt Sparks, Kenar Jhaveri and Edgar Lerma to take pie and write a check.

#NephMadness is back

Last Sunday we launched NephMadness
for the third time. This began as a last minute Hail Mary by the crew at AJKDblog to commemorate World Kidney Day in 2013. The response was so overwhelming that despite initially thinking this would be a one-and-done we decided to come back and improve the idea.

We have steadily improved the execution of NephMadness.

Last year we introduced a system to allow online bracket submissions. We found a company that provides white labelled online tournament brackets. This gave us streamlined registration and allowed for automatic scoring. Participation sky rocketed. Last year we also brought in content experts to act as our selection committee to make sure we had the best field possible.

This year, we have a number of further improvements. The primary complaint last year was seemingly arbitrary way the winners of each match up were determined, basically it was a system we called "Matt and Joel decide." Not surprisingly people were not enamored with this system and this year we have deputized a blue ribbon panel of nephrology experts to make the decisions.

We are also getting better at producing the brackets themselves and filling out the field. We now have written on 192 concepts since we started NephMadness. We have seen that the best match-ups pit related concepts up against each other and we have really increased the use of that technique in this year's brackets. In addition we have themed the entire tournament as nephrology's interaction with other specialties.

We have also changed the schedule. The first two years we tried to track the schedule of March Madness as closely as possible. This meant we opened the brackets on Selection Sunday and closed them a week later. This year we opened the brackets on March 1 and accept submissions for 3 weeks, until March 22. This will, hopefully, increase participation.

Another area of improvement is in the Tourneytopia rollover descriptions. Last year we just copied the scouting reports from AJKDblog and pasted them in to the roll overs. They had a bunch of links and were really long. This resulted in really long descriptions that were difficult to read in the rollovers. This year we have a short 2-3 sentence description for the rollovers written solely for that purpose. Oh and a picture.
Go to Tourneytopia to submit your brackets for NephMadness
Last year we had a confusing collection of three sites, Tourneytopia, NephMadness.com and AJKDblog. This year we jettisoned NephMadness.com and completely redesigned AJKDblog to be a much more effective container for NephMadness. The editorial staff at AJKD really did an outstanding job with the redesign.

This year the journal, AJKD, is really behind the contest. The Feb and March issues of AJKD had pack ins to promote the contest.

And the journal website has two high profile ads for NephMadness.



The last change is we are partnering with MedScape, a long time partner with the NKF and AJKD to promote NephMadness. Medscape is republishing all the content from the scouting reports and e-mailing their audience.
At St John Hospital and Medical Center we are having all of our fellows and faculty complete their own brackets and then we will have a consensus conference and build a collective entry to see if we can do better as a pit crew or as lone cowboys (and cowgirls).

Twitter Chat Tonight, Tuesday Feb 24 about World Kidney Day

I have been involved in Nephrology social media for years now, and it has been rewarding seeing the global community of nephrologists connect and develop a voice over that time.

While social media in general and Twitter in particular was once thought of as a time waster, it is now recognized as critical communication channel that allows back and forth communication as well as side to side communication.
First order communication: traditional top down

Second order communication: back and forth

Third order communication: back and forth and side to side
The side to side communication is what builds the community and is what twitter excels at. Imagine how boring the NephJC chats wold be if the only communication you saw was from the NephJC host? The whole point of the chat is to leverage the diversity of expertise in the crowd. 

Tonight will be a first in social media. Representatives from the International Society of Nephrology, The American Society of Nephrology and the National Kidney Foundation will be convening to discuss the upcoming World Kidney Day. It should be a great discussion. Please join us in (dare I say?) this historic moment. The discussion starts at 9PM EST and the hashtag is:

#WorldKidneyDay

More information, including who the representatives are, is available on Medium.

Must know facts about albumin! Number seven will blow you away!


Albumin is made in hepatocytes at a rate of 200 mg/kg/day - Created with Haiku Deck, presentation software that inspires





Improving albumin levels among hemodialysis patients
  1. Albumin is made in hepatocytes at a rate of 200 mg/kg/day 
    1. or 14 g in 70 kg person
  2. Total body albumin is 4-5 g/kg
  3. 40-45% of albumin is in the intravascular space
  4. Normal albumin concentration in the interstitial space is 
    1. 0.7 in fat and 
    2. 1.3 in skeletal muscle
  5. Albumin has a half life of 2 to 3 weeks
  6. The drop in albumin with inflammation is due to: 
    1. reduced synthesis and 
    2. increased fractional catabolic rate (FCR)
  7. Intradialytic weight gain of 2.8 liters (4% in a 70 kg man) will dilute the albumin down 0.8 g/dL

Potassium Wars, The Grand Rounds Presentation.

Last week I delivered my grand rounds to both St John Hospital and Providence Hospital. This grand rounds on Kayexalate and the new therapies to increase colonic potassium clearance. Take a look. I hope you enjoy. I have more to say about this talk, and hopefully I will do a directors commentary of the presentation. I have 99 problems but have no for that time now.

ASN Quiz and Questionnaire 2014: Acid-Base and Electrolyte Disorders

CJASN just published two answers to the Electrolyte quiz from ASN Kidney Week, unfortunately they have the answers right next to the questions, so you can't take the test honestly, Here are the questions, without the answers. Get the article here.


Case 1: Mitchell H. Rosner (Discussant)
A 60 year-old man with a history of a heart transplant and stage 4 CKD was diagnosed with a gout flare 6 days ago and was prescribed prednisone, 30 mg daily; allopuri- nol, 100 mg daily; and colchicine, 0.6 mg three times daily, for the first 2 days and then colchicine, 0.6 mg twice daily thereafter. Before the gout attack, the patient had been feel- ing well and his baseline creatinine was 2.9 mg/dl with an eGFR of 29 ml/min per 1.73 m2. Other medications in- cluded mycophenolate mofetil, cyclosporine, pravastatin, carvedilol, calcitriol, and furosemide.
After 48 hours of taking the allopurinol, colchicine, and prednisone, the patient developed nausea, intermit- tent vomiting, and profuse diarrhea. This continued in- termittently over the next 2 days. However, during the past 2 days, he has developed worsening lethargy; muscle aches; and continued nausea, diarrhea, and abdominal pain. His family brings him to the emergency depart- ment (ED).
In the ED, he was found to be confused, tachycardic, and hypotensive, with a BP of 76/42 mmHg and pulse of 120
beats/min. He then sustained respiratory arrest and was successfully intubated; he was also started on vasopressin, norepinephrine, and intravenous fluids to support his BP. Laboratory results at the time of admission are shown in Table 1.

Question 1a
The acid-base abnormality in this patient is:
     A. Aniongapandnon–aniongapacidosis
     B. Respiratoryacidosisandaniongapacidosis
     C. Respiratoryalkalosisandaniongapacidosis
     D. Respiratory acidosis and anion gap and non–anion gap acidosis
     E. Respiratory alkalosis and anion gap and non–anion gap acidosis 

Question 1b
Which of the following drug interactions were likely responsible for the patients presentation?
     A. Allopurinol,pravastatin,andmycophenolatemofetil 
     B. Allopurinol,pravastatin,andcyclosporine
     C. Colchicine,allopurinol,andmycophenolatemofetil
     D. Colchicine,pravastatin,andcyclosporine 
     E. Colchicine,prednisone,andpravastatin 


Case 2: Mitchell H. Rosner (Discussant)
A 37-year-old woman with a 3-year history of severe sinus disease and headaches is referred to you after several laboratory abnormalities were found. Her medical history is significant for two episodes of nephrolithiasis (no stone analysis was per- formed). On questioning she notes that pain and redness develop in her hands in cold weather. She takes no medications except for occasional antibiotics for her sinus problems. Her BP is 108/50 mmHg and her physical examination is unremarkable except for some fullness over her parotid glands. Her laboratory studies are shown in Table 2. On further questioning, she reports no drug abuse.

Question 2a

Which one of the following laboratory tests would you order next?
     A. Serumandurineproteinelectrophoresis 
     B. Plasmareninandaldosteronelevels
     C. 24-hoururinecortisol
     D. Stool screen for laxative abuse
     E. Anti-SSA,Anti-SSBserologies 

Aggressive intravenous potassium chloride and oral potas- sium citrate supplementation are administered. Laboratory tests repeated 1 week later reveal the following: potassium, 3.5 mEq/L; bicarbonate, 15 mEq/L; and anion gap, 6. The patient is seen by a neurologist for her chronic headaches, and topiramate, 200 mg daily, is started.

Question 2b
Which of the following changes would be expected if lab- oratory work was repeated several weeks after initiation of topiramate?
    A. Potassium,2mEq/L; bicarbonate, 5mEq/L; aniongap,8 
    B. Potassium,4mEq/L; bicarbonate, 20mEq/L; aniongap,8
    C. Potassium, 4 mEq/L; bicarbonate, 5 mEq/L; anion gap, 15 
    D. Potassium, 2 mEq/L; bicarbonate, 5 mEq/L; anion gap, 15
    E. Nochangeinelectrolytesfrompriorvalues

What am I going to do with all of these draft posts?

I have been blogging at PBFluids since 2008 and have 737 posts. What has been slowly growing is the number of unpublished drafts. Mostly this is clever ideas not fully realized like this evocative title:


There are others that if published would be career suicide like my completely overly honest reviews of the ASN Board review with letter grades for each of the speakers. The GPA was 3.7 but there were some clunkers in the mix:


The number of drafts is as of now 70 posts. I am going to try to salvage some of these posts and put them on the blog.

The first is a post titled "Epic ASN Post" This is from Kidney Week 2011. The post was written 12/1/11.

Landed in Philly and went to the AirBnB room I found. Seventy-five bucks a night and only a mile from the conference center. Awesome!

FourSquare, remember when that was a thing?

ASN #NephWorkForce TwitterChat on Tuesday January 13 at 9pm EST

Mark Parker, the chair of the ASN Workforce Committee, will be on Twitter next Tuesday to discuss the latest report. This report is the second done by Ed Salsberg and his colleagues at GWU. This report is all about the fellow experience in getting a job.

The report is available here.

Dr. Parker answered some questions to stoke the fires of discussion, that interview can be seen on Medium.

ASN Nephrology Workforce Report

The first workforce report stimulated some discussion on Twitter, that discussion is saved here:



A summary of the discussion about the second report so far is available here:

My summary of the report:


  • The survey was distributed to 1,530 ASN Nephrology fellow and trainee members in June and July of 2014.
  • 441 responded. Response rate of 28.8%.
  • There are 930 fellows in ACGME accredited programs and they received 333 responses from this sub-group. 
  • What is up with the 600 trainees not in ACGME spots? DO programs?
Interesting gender differences:
How about this eye opening stat:
USMGs had a median debt of $100,000 to $149,999. IMGs were significantly different with a median debt of $0 and 65% having no debt.

Career plans

Nephrology breaking barriers, has higher starting salaries for women compared to men:
Female respondents had a slightly higher median anticipated base income than male respondents, who had a median anticipated base income of $150,000 to $174,999.
Job hunting troubles were much more common among IMGs with only 22% finding a satisfactory job compared to 56% of USMGs. Visa problems and unappealing locations were leading problems in job hunting. 71% reported no or very few jobs within 50 miles of their training location.

Happily 72% of respondents indicated they would recommend nephrology to medical students and internal medicine residents.

It's an interesting report, take a look and...

Why we needed Kayexalate in the first place

In February I'm giving grand rounds on the Potassium Wars (what, you didn't realize we are in the opening stages of the potassium wars?). I was looking at the original research on Kayexalate from 1961 and came across this ad. Check out the doses of spironolactone they were slinging:


400 mg of spironolactone, daily and this is in a world without loop diuretics!

Purple Urine, now that's not something you see everyday

From the NEJM 2007.


Purple discoloration can occur in alkaline urine as a result of the degradation of indoxyl sulfate (indican), a metabolite of dietary tryptophan, into indigo (which is blue) and indirubin (which is red) by bacteria such as Providencia stuartii, Klebsiella pneumoniae, P. aeruginosa, Escherichia coli, and enterococcus species. The clinical course is benign, and the urine typically clears with resolution of the bacteriuria and acidification of the urine. 


H/T Life in the Fast Lane

The first Nephrology Social Media Internship

A few pioneers at the intersection of social media and nephrology have banded together to create an internship in social media. The founding members of the loosely coordinated Nephrology Social Media Collective (logo pending, but it should be pretty cool) are:

  • Myself
  • Swapnil Hiremath, co-founder and brain child of NephJC
  • Matt Sparks, savior of Renal Fellow Network and co-creator of NephMadness
  • Kenar Jhaveri, blogger at NephronPower and editor of AJKDblog
  • Paul Phelan, contributor to NephJC, Renal Fellow Network and AJKDblog
  • Jordan Weinstein, creator of UKidney
  • Edgar Lerma, creator of #NephPearls hashtag and serial author
The idea behind the internship is to give guidance to doctors or students who want to become experts in social media. There are a number of different techniques and strategies in social media and we will provide the intern an opportunity to work with these techniques first hand. Projects that will be open to the interns include:
  • NephMadness
  • NephJC
  • AJKDblog
  • Renal Fellow Network
  • Research
  • UKidney
  • DreamRCT
Technologies that the intern will be exposed to include:

  • Podcasts
  • Google hangouts
  • Tweet chats
  • Storify for curation
  • Mail Chimp newsletters
  • Twitter analytics
  • Google analytics
  • multiple blogging engines including:
    • Blogger
    • WordPress
    • Medium
    • SquareSpace
But more important than the technology, is that the interns will have access to our collective wisdom and have access to an instant personal learning network to allow them to pursue their personal social media goals. This is the first time we have done this and we are still working out the exact curricula, but if you are in nephrology, residency or medical school and want to learn how to leverage the power of social media consider applying for the position.
