If it wasn't from the pages of the New York Times I wouldn't believe it.
Please join us on #NephJC, Tuesday at 9PM EDT and Wednesday at 8PM GMT for a discussion of proper medical director behavior.
The NephJC 23 (warfarin) American chat Storify - and analytics
It was pretty well attended...
So was the GMT chat next day...
and the GMT chat storify of NephJC 22
Nikhil does the BK storify
So our NSMC intern, Nikhil Shah not only did a super job of writing the sumary up for the BK virus #NephJC 22, he also has done a great job of curating the first chat into a storify.
NephJC 22: GMT chat
The American chat (mostly by virtue of its longevity) still has more participants and tweets, but the GMT (EU/African) chat makes up by being fun and entertaining. Tom Oates, Paul Phelan, Francesco and their merry band of tweeters make for delightful reading. Jungle Juice, scud missiles and more. See some highlights below
#NephJC number 22 is in the can.
The BK nephropathy discussion was interesting. No one was interested in further exploring quinolone for BK, which I guess indicates that this was a compelling study.
All and all it was a very interesting discussion and I learned a lot.
Storify forthcoming.
Palliative care chat #HPM on Wednesday at 9EST
March is Kidney awareness month and in honor of that, Pallimed, the Hospice and Palliative Care Blog is talking about intersection of nephrology and palliative care. They asked NephJC co-creator, Joel Topf to host their chat. This happens on Wednesday. Topf wrote the introduction:
Have you ever read a journal article and as soon as you finished the abstract you had this forbidding feeling that if the authors actually proved what they claimed to have discovered your medical life will never be the same?
This happened when I read, Functional Status of Elderly Adults before and after Initiation of Dialysis by Tamura et al. in 2009.
The study simply looked at mortality and functional status of nursing home residents who initiated dialysis. The cohort consisted of 3,704 Americans. The average age of this predominantly white (64%) female (60%) cohort was 74 years. The outcomes were horrifying:
- Within three months of starting dialysis 61% had died or had a decrease in their functional status
- By one year that figure was 87%
- By one year only 1 in 8 patients had maintained their functional status from before dialysis
While this study did not track patients who deferred dialysis it is hard to imagine they could do much worse. The view of dialysis as a way to improve functional status by clearing uremia leading to improved nutrition and other downstream benefits was revealed to be a false hope. Instead we have a treatment that appears to be too rough for frail, at-risk patients and left them significantly worse than they were before dialysis.
The discussion section of the article had a sentence that should be embroidered to every nephrologists white coat:
“...kidney failure may be a reflection of terminal multiorgan dysfunction rather than a primary cause of functional decline, and thus the initiation of dialysis may not rescue patients from an inevitable decline.”
As nephrologists we need to elevate conservative, non-dialytic, therapy to be a clear option for patients, one that should be discussed along with peritoneal dialysis and transplant. Conservative care should not merely be a last resort when all other options have been exhausted.
I hope you will join us as we discuss the intersection of nephrology and palliative care this Wednesday at #hpm chat.
from NephJC live to the Lancet
You might remember Perry Wilson, the young dapper nephrologist from Yale who presented his trial on AKI alerts at NephJC live a few months ago. He was tweeting as @nephrolalia - and has now renamed and rebranded himself as @methodsmanmd, which is quite apt given his recent blog posts and succinct and snappy videos up at MedPage Today.
More notably, the data he presented at #NephJC live has been published today - with some great additional analyses, in the Lancet. We sure know how to pick winners - so the next time we come calling, pick up the phone!
Tweet of the Week: Urine Eosinophils and NephroCheck
Dr. Faubel nailed the best comment about NephroCheck by reminding us while we pick apart the particulars of NephroCheck that we have some other dragons to slay:
And then Edgar slides in with the appropriate #NephPearl (How does he do that so fast?)
#NephJC 20: Who checks the checkers? Storify Part 1: EST chat
Last night we were off to a rollicking start with a great #NephJC chat - in great part due to the participation of Azra, Jay and Sarah! Joel took no time - burning the candle at both ends to do some storifys.
Here is the entire unedited archive with all the tweets from both chats:
Topic 0: Introduction, and How we do diagnose AKI?
Topic 1: Discussing DISCOVERY, SAPPHIRE and TOPAZ
Topic 2: ROC Curves and Diagnosing Aki with Nephrocheck
Topic 3: What happens now?
The GMT chat today was also very intense - Storify will follow shortly!
The EST and GMT #NephJCs continues to kill it
Symplur don't lie
NephJC number 20 had the second most tweets and the third most participants. Thanks everyone for participating.
Live from San Diego it's Claudio Ronco and John Kellum
Discussing biomarkers.
KDIGO AKI staging
Tonight's journal club requires knowledge of the KDIGO acute kidney injury stages. These are nearly direct translations from the previous AKI staging systems.
- RIFLE: the first system. KDIGO 1, 2, 3 roughly corresponds to R, I, F. The primary difference is KDIGO categorizes people with just a 0.3mg/dL rise in Cr as AKI, RIFLE does not.
- AKIN: As far as I can see AKIN 1, 2, 3 is identical to KDIGO 1, 2, 3.
New for NephJC tonight: Topics
In case you haven't signed up for our mailing list (really - why not? go there and do it now!) - We are going deep on the FDA approved NephroCheck™, a new test for the early diagnosis of AKI. This is not industry sponsored BS, just honest, crowd-sourced, EBM.
For this #NephJC we have three topics we want to discuss:
*please preface your tweets with the topic: i.e. T0, T1 and so on*
Topic Zero: How are you currently diagnosing AKI?
- Is it all FENa and a microscope slide?
- What do you think of the KDIGO AKI stages?
- How do you use oliguria?
Topic 1: Evaluate their strategy for developing a novel test for AKI.
Three studies in 2 papers:
Discovery: the scientists tested 340 biomarkers and came up with a pair that performed best. N=522.
Sapphire: validated the biomarker from Discovery in a unique cohort. N=744.
Topaz: A separate study just to validate the results of Sapphire. N=420.
Is this a compelling story line? Is this a fair way to discover and validate a test? Do you agree with the conclusions?
Topic 2: Evaluating a test.
- On ROC the area under the curve was 0.82. Good enough?
- Two cutoffs are provided, one is sensitive (92%) and the other is specific (95%). How will you use that?
Topic 3: So what?
- How will having a 12 hour lead time change your management?
- Should we expect trials designed to change the course of AKI to use NephroCheck™?
GMT NephJC gaining steam
Tom Oates and his merry gang of GMT chatters shattered previous records for the Euro/Afro chat. Great work guys!
Not quite up to the pace of the western hemisphere, but gaining fast.
In a related note, NephJC.com reached 4,000 page views in a month for the first time in January.
Follow-up from the Meso-American Nephropathy NephJC
From the International Journal of Occupational and Environmental Health comes this article looking at Changes in kidney function among Nicaraguan sugarcane workers. The article is behind a paywall but according to the NPR article it exonerates the fertilizers and pesticides and adds to the data on chronic and recurrent dehydration as the culprit:
“But this new study casts doubt on that theory. It found that field workers whose primary jobs were spraying for weeds and pests (and who thus had the most contact with agricultural chemicals) had the least decline in kidney function over the course of the harvest.
The researchers also found that dehydration among workers with the most physically demanding job — cutting cane — could contribute to the illness.”
I found this bit interesting:
“Cutters who drank more of a generic energy drink while on the job had less of a drop in kidney function than co-workers who drank less of the beverage.”
If the energy drink is protective that seems to counter the fructose/uric acid hypothesis that Dr. Johnson was proposing in his article. This continues to be one of the most interesting stories in nephrology.
Tweet of the night
We had a great NephJC last night. We had a new contributor who was excellent, Eric Weinhandl of Minnesota.
Dr. Weinhandl works with the new PEER Kidney Care Initiative. It looks like a cool project. Here is some press from Nephrology News and Issues.
Noteworthy in Nephrology Social Media
The latest NephJC newsletter was just pushed out. For the second week there is a section that calls out what is new or noteworthy in the nephrology social media sphere.
This week's letter calls out Nikhil Shah's new nephrology blog, Nephrology Tweetbook and Fred Coe's kidney stone blog. We started identifying highlights last week. In the inaugural edition we identified the work being done by Tejas Desai and one of the latest nephrologist on Twitter, Dr. Ratna Samanta.
If you see or hear of anything that should be promoted on Noteworthy in Nephrology, drop us a tweet.

If You Don't Know What RSS Stands for and Would Like to Know
RSS (Rich Site Summary - or really simple syndication as it is known more popularly) refers to a family of web formats that is used to publish information for frequently updated web sites, like blog posts, newspaper headlines and journals. Subscribing to a website RSS removes the need for the user to manually check the website for new content. In addition, by entering these 'feeds' into an aggregator or feed reader (Feedly is our current favourite - since Google decided to nix Google Reader), you will have all that content 'pushed' to you, notifying you of new posts. That's our secret to knowing the latest article published in Lancet. Look for this icon to find RSS feeds for your favourite website:
There are many advantages to using RSS feeds - you can get all the content you consume into one 'reader' i.e. news, medical journals, blogs etc. And, in addition, you can skim the headline, or the abstract - and decided if you want to click the link to read the full article in the original website. Enjoy!
New kid on the block: #RheumJC
The rheumatology crew that killed it during the Rituximab for ANCA vasculitis NephJC are striking out on there own with an ambitious plan for their own twitter journal club. They are kicking it off this coming Thursday with a GMT and EST at the exact same time as our NephJCs, 8GMT and 9EST. They are then doing a consolidation wrap up discussion the following day.
The first topic is one near and dear to all of our hearts, lupus nephritis. RCT of tacrolimus versus MMF for induction.
It would be great if some of our community could support the rheumatologists as they launch their journal club.
