Over at microBEnet I have a post that may be of interest to many readers: Best practices for sample processing and storage prior to microbiome DNA analysis freeze? buffer? process? | microBEnet: the microbiology of the Built Environment network. Basically I am hoping to get a discussion going about the ins and outs of sample processing and storage for microbiome studies. We have been having lots of discussions in my lab and with collaborators about this and thought it would be better to just get everyone involved.

Gender and tenure diversity and Github teams (from #UCDavis)
OK this is very interesting: Having higher gender and tenure diversity is associated with higher productivity in GitHub teams. - Computer Science
Thanks to the UC Davis College of Engineering Twitter Feed for pointing me to this
Study: Higher gender + tenure diversity associated with higher productivity in GitHub teams, http://t.co/qHXOvMmGKb @github @phylogenomics
— UC Davis Engineering (@UCDavisCoE) January 23, 2015
The paper behind this is available as a preprint here.
Abstract:
Software development is usually a collaborative venture. Open Source Software (OSS) projects are no exception; in- deed, by design, the OSS approach can accommodate teams that are more open, geographically distributed, and dynamic than commercial teams. This, we find, leads to OSS teams that are quite diverse. Team diversity, predominantly in of- fline groups, is known to correlate with team output, mostly with positive effects. How about in OSS?
Using GITHUB, the largest publicly available collection of OSS projects, we studied how gender and tenure diversity relate to team productivity and turnover. Using regression modeling of GITHUB data and the results of a survey, we show that both gender and tenure diversity are positive and significant predictors of productivity, together explaining a sizable fraction of the data variability. These results can inform decision making on all levels, leading to better out- comes in recruiting and performance.Really, really fascinating.

Trials and tribulations with the "UC Care" medical plan & w/ UCSF, UC Davis health systems
The University of California healthcare options are, well, less than ideal right now, in my opinion. Here is a little story about my recent experiences.
September 2014.
Forced to switch to the UC Care health plan because UC cancelled the health plan that allowed me to be a part of the Sutter Medical Group. Sutter has always been awesome. Wonderful care. Wonderful people. Rapid scheduling of appointments. And I was very sad to be forced to switch. I kept my primary care physician at Sutter but realized I would have to switch for many other things.
I was not pleased to be pushed into the UC Care plan because my experience with the UC Davis Medical Group has been beyond disappointed in the past. For example see this: U. C. Davis Medical Group - their time is MUCH more important than yours. Admittedly, I had not been to people in the UC Davis group in a while, so -- maybe things had changed.
Plus I was pleased to note that the UC Care said I should choose their plan if "You want direct access to all providers without a referral." Why yes, that sounded good. Hah hah hah. Silly me.
September 2014.
Of course. Just as I switched medical groups I had a serious health issue in need of attention. Called UC Davis Nuerology to make an appointment with the specialist recommended by a colleague. They told me I needed a referral. I told them I had UC Care health plan which says I do not need a referral. They said that it did not matter what plan I had, I needed a referral. So I asked my doctor for a referral.
October 2, 2014.
Meanwhile I wrote to one of the people in the UC Davis Neurology Department where I wanted an appointment to ask how I should make an appointment and told him that I had been referred to him by a UC Davis MD (trying to pull some sort of nepotism here). He connected me to his assistant and I sent her the info she asked for.
October 13, 2014.
I had not heard back from his assistant so I wrote to her again.
October 19, 2014.
I received a letter in the mail from UC Davis "reminding" me I had an appointment in Neurology scheduled for December 17, 2014.
Now, I guess it was nice to have an appointment. But I note - they never called me to ask when would be good for an appointment. They never contacted me at all. And this was clearly less than ideal - an appointment in two months.
So I called them to ask - how did this get scheduled? They said they must have scheduled it with me. I told them, no, nobody even contacted me. I then asked - is there anything sooner? Nope. I then asked - what if I cannot make that date and time (I was scheduled to be away). They then said that would cause a significant delay in the appointment. What the $*@#$8? This is not the first time I have had trouble scheduling appointments with UC Davis physicians but this was absurd. I then asked - is there anything I need to do in advance? They said nope. So I waited. Two plus months. For an appointment for which I needed a referral even though I had signed up for UC Care. Oh - and - I guess just to prove they had no clue what they were doing - they spelled ny name wrong (Johnathan).
December 17, 2014.
I had my appointment with the neurology specialist. He was very nice. Seemed pretty knowledgeable. He had some disconcerting misconceptions about me and I tried to correct them but he did not seems to be paying attention. He did not do any of the more complex tests I had seen in the literature that were standard in the literature I had seen for my condition. He did not even order any such tests. He concluded the visit with a possible diagnosis and then said he needed to order a series of blood tests to test some alternative possibilities. They decided I did not need a follow up appointment and that we would wait to see what the blood tests showed before deciding what to do next. I told them I was not fasting and asked if that mattered and they said no (one of the reasons I ask in advance about blood tests is that freuqently they need me to be fasting and it is easier to do that early in the AM ... but nevermind that ... they said it was not needed).
December 22, 2014
I signed up for Mychart.ucdavis (based on the recommendation from the printout I got when I left the doctor's office)-- an online system to communicate with the UC Davis Medical Group.
December 23, 2014
I got an email saying there were test results in Mychart.
January 2, 2015.
I still had not heard anything from the doctor's office. I wrote to him via the MyChart system asking if he had any update based on the test results. I called too. No response.
January 6, 2015.
I finally got a message from my doctor. It had my name wrong, again, in a different way (John). The message was short, had one useful thing in it and then said he "You need to check in with your PCP-- I have instructed our staff to contact your outside PCP and transmit labs to him and to contact you." So much for seeing a specialist directly and communicating with them. Oh, and he ended the message with "Good we checked labs and caught this now before your travels." What the $&##? I had no travel plans. This had nothing to do with travel. He spelled ny name wrong. They had me listed as having type II diabetes, when I have type I. And they wanted me to communicate with my primary care physician instead of him. Such excellent care. Oh, and he made a comment about my vitamin B levels being too high when I had told him I was taking a specific prescribed vitamin therapy and that I had taken some that AM (this would likely screw up the blood test - I think to know if vitamin levels are off one has to NOT have recently taken vitamin pills). Jesus Christ what a sham. In fact, when I told him I was taking this vitamin prescription, he said something to the effect of "random vitamins don't usually help" and I said "it is not random it is actually prescribed and there are clinical trials showing it has some benefits" but he had never heard of it nor did he seem to care.
January 7, 2015.
I decided, I needed to see another specialist. So I went back to a recommendation from another colleague for someone to see at UCSF. So I checked out the protocol for making an appointment at UCSF and I filled out an online form to request such an appointment. In the request system it asked for the preferred method of contact for me, and I said email.
January 8, 2015
A day or so later, I received an email from their system which said I had an encrypted message regarding my appointment request. I had to create a new log in to a new system in order to read the message about my appointment request. The message started with the following:
And finally I got contacted by someone who actually seemed to care.
UPDATE January 29, 2015
Still no call back from UCSF Neurology despite their promises that they would call my doctor and then call me back as soon as possible. Unbelievable.
UPDATE January 29, 2015 #2
Wrote an email directly to the Doctor I wanted an appointment with.
UPDATE January 29, 2015 #3
Tried to contact the appointment desk. Was on hold for 30 minutes before I had to hang up.
UPDATE January 30, 2015
Got through to the appointment desk. OMG how ridiculous. They said they needed to transfer me to another department (memory and dementia) because that was where I had the referral (I had asked for an appointment in neurology, I have some peripheral neuropathy). They said the doctor at UCSF had reviewed my chart and that is where they determined I needed an appointment. And that I would need to contact my doctor about this.
What the F#*$*#? Completely insane.
UPDATE February 2, 2015
Lesson of the day. UCSF doctors and personnel, other than the receptionist I interacted with on the phone, really really really do care about getting things right. After I posted again about this issue to Twitter and sent an email to my brother who forwarded it to people at UCSF, many people stepped up to try to help. All of them have been incredibly gracious and concerned and helpful.
And at the same time I decided to get a copy of the referral from my primary care physician just in case there was a mistake from their end.
And, well, there it was. The referral was to see a neurologist for diabetic related neuropathy issues. Looked good. Then I looked at page 2. And there was a comment about my having a history of dementia and that they could not do an MRI due to my pacemaker. Well. WTF? What chaos.
Certainly this explains why UCSF thought I should see the dementia clinic. It does not explain why UCSF neurology would never return my calls and was rude on the phone, but, well, it does make me feel like a schmuck for the mistake my doctor's office made.
UPDATE February 2, 2015 1:45 PM
Finally - a call from UCSF. Yay. And they are going to contact my docs office and confirm that I do not have dementia. And then, maybe then, I will get an appointment.
UPDATE February 2, 2015 5:45 PM
Well, I got a call from the UCSF Neurology appointment desk. The person said they were calling because I had apparently contacted another doctor who contacted them (were they pissed off about this? sounded like it). And they told me the first appointment was April 19. Wow. That is, like, not soon. Lovely. I took it. But am going to see if there is a way to move it up.
UPDATE April 19, 2015
So - I finally had my appointment with a Neurologist at UCSF. I had to get up so so early for my 9 AM appointment at UCSF Parnassus campus. I was planning to take the train at 5:45 AM and then somehow wind my way to the UCSF campus. And my alarm was somehow silenced. I woked up at 5:30. And I literally threw stuff in my bag and changed and jumped in my car. But there was just no way to make it. And so I decided to suck it up and drive into SF. Traffic was bad already that early. And I was pretty wiped when I got to UCSF. And I was prepared for the worst.
But OMG. What a difference. I was treated so incredibly well by everyone there. The information desk people on the 1st floor were helpful. The lab people where I went for blood tests afterwards were pleasant and helpful. The staff in the Neurology Department were friendly and respectful and helpful. And my doctor. Wow. She was just so great. Yes I do have some neuropathy. And yes indeed it does completely suck. And yes it still freaks me out and stresses me out. But now I finally feel like I am getting excellent medical care. And that is uplifting, even though my health is imperfect. Such a contrast compared to the awful experience at the UC Davis Neurology
UPDATE April 21, 2015
Got a call from a UCSF Neurologist to discuss my blood test results. My doctor was not available so an alternative doctor called me. And she was phenomenal too. Spent quite a while on the phone discussing things. Came up with a plan. All based on actual science.
UPDATE April 22, 2015
Got my medical report in the mail from UCSF. Incredibly detailed report about my appointment, recommendations for me, and more. Another wonderful feature. I have STILL not gotten any such thing from UC Davis.
September 2014.

I had not heard back from his assistant so I wrote to her again.
I am writing to see if you got this information I sent Oct 3 and if there is any more information you need from me. ThanksI again did not hear back.

This email is to acknowledge receipt of your online appointment request for a new patient appointment. We have been unsuccessful in reaching you by phone. Before an appointment can be approved for scheduling we will need the following required documents to start the review process:
· Referral along with reason or diagnosis
· Pertinent clinical notes or records
· Pertinent test results
· Front and back copy of insurance card and authorization if required by insurance
· Patient demographic information
What? Why did they ask for my preferred means of contact if they were then going to call? Oh well, at least this got through. I called to ask some questions and only got a machine so I left a message.
Janaury 12, 2015
Appointment with my primary care physician. He told me they had not received any information from the UC Davis specialist. But he agreed that it might be good to see a specialist who gave a shit (my words, not his). So he said they would make a referral to UCSF for me. I gave them the printout with the information requested from UCSF.
Janaury 17, 2015.
Got an email saying my doctor had sent over the referral information to UCSF. Called UCSF on MLK day and alas they were not open. But I left another message asking what I had to do to make an appointment.
January 19, 2015.
My wife took down a message and gave it to me saying UCSF had called about making an appointment.
January 22, 2015.
I called UCSF Neurology. It took a long long long time to get through to a person. When I finally did, I said I was calling to set up an appointment. The person was immediately somewhat rude. I gave my name and DOB and the person said I had no referral and my record there was empty. I said I had been called by UCSF and they had left a message saying I should call about an appointment. Now, mind you, I am not sure why UCSF had called me - it could have been about setting up an appointment or it could have been just to return my call. But regardless, I told the receptionist that my doctor's office had told me they had contacted UCSF and that I should call. The person repeated that they had no record of anything in my file - no calls to me - nothing. This sounded so weird that I said "Is this definitely the file for Eisen - E-I-S-E-N." and the person snapped back "I do not make spelling mistakes" or something like that. Nice. Eventually, the person transfered me to someone else who actually offered to help and to call my doctor's office. They then said they could call me back after this. I asked what number they had and the number they said was not one I recognized. Weird. But I gave them the correct number and then hung up.
After I hung up I started to get pissed off. What was the deal here? I signed up for this UC Care health insurance beause I was supposed to be able to make appointments with specialists without referrals. And I am a UC Professor - with an appointment in a medical school. I probably get treated better than the random person. What a scam. And then I remembered how badly UC Davis Medical Group treated my wife many years before. And how good the treatment we received from Sutter has been. So I posted something to Twitter.

Absence of women from Middle East policy debates
For those who think about the underrepresentation of women in science meetings - this may be of interest: The mysterious absence of women from Middle East policy debates - The Washington Post. 65 percent of the events in Washington DC relating to the Middle East had no female speakers. Disheartening and something that needs to be dealt with.

So so so cool: Tangible Interactive Microbiology for Informal Science Education
This is so cool: Tangible Interactive Microbiology for Informal Science Education.
Abstract:
I would post a picture here but they discourage it. So you will just have to go look for yourself. The PDF is free, at least for now.
Abstract:
We present an interactive platform that enables human users to interface with microbiological living cells through a touch-screen, thereby generating a tangible interactive experience with the microscopic world that is hidden to most people. Euglena gracilis, single-celled phototactic microorganisms, are imaged and optically stimulated via a microscope setup equipped with a projector and a touch- screen display. Users can directly interact with these organisms by drawing patterns onto the screen, which displays the real-time magnified view of the microfluidic chamber with the motile euglena cells. The drawings are directly projected onto the chamber, thereby influencing the swimming motion of the cells. We discuss the architecture of the system and provide exploratory user testing results in a facilitated setting, which shows engaging nature of our system for children and the general public. In conclusion, our tangible interactive microscope allows artistic expression and scientific exploration with the ease of “child’s play.”And check out this video.

The best writing in science papers: Part II
Guest post by Stephen Heard
(scientistseessquirrel.wordpress.com)
Over 2 years ago now, Jonathan posted “The
best writing in science papers: Part I”. I stumbled across that post and searched excitedly for Part
II – only to discover there wasn’t one.
Well, now there is, as Jonathan has kindly allowed me to guest-post
this.
Jonathan’s Part I identified the butterfly-taxonomy
papers of Vladimir Nabokov as containing flashes of beautiful writing, and I
agree (although my favourite bits differ from his). But Jonathan wondered if picking Nabokov (an acclaimed
novelist) was “a bit unfair” and he later told me he’d never done a Part II
because other examples were too hard to find!
Actually, other examples can be found, and not
only in the papers of scientists who are also accomplished novelists. I collected a few in my recent paper “On whimsy,
jokes, and beauty: can scientific writing be enjoyed”. For example, here is Nathaniel Mermin on a
surprising result in quantum mechanics:
“There are no physical grounds for insisting that [Alice] assign the same value to an observable for each mutually commuting trio it belongs to – a requirement that would indeed trivially make her job impossible. The manner in which the nine-observable BKS theorem brings Alice to grief is more subtle than that. It is buried deep inside the mathematics that underlies the construction that makes it possible, when it is possible, to do the VAA trick.”
Here is Bill Hamilton setting up a simulation
model of antipredator
defence via herding:
“Imagine a circular lily pond. Imagine that the pond shelters a colony of frogs and a water-snake…Shortly before the snake is due to wake up all the frogs climb out onto the rim of the pond… [The snake] rears its head out of the water and surveys the disconsolate line sitting on the rim… and snatches the nearest one. Now suppose the frogs are given opportunity to move about on the rim before the snake appears, and suppose that initially they are dispersed in some rather random way. Knowing that the snake is about to appear, will all the frogs be content with their initial positions? No…and one can imagine a confused toing-and-froing in which [desirable positions] are as elusive as the croquet hoops in Alice’s game in Wonderland.”
And here is Harry Kroto describing the structure
of C60 buckyballs:
“An unusually beautiful (and probably unique) choice is the truncated icosohedron...All valences are satisfied with this structure, and the molecule appears to be aromatic. The structure has the symmetry of the icosahedral group. The inner and outer surfaces are covered with a sea of Ï€ electrons.”
Finally, read
this by Matthew Rockman – too much, too good, to even excerpt here.
It could be that writing beautifully in scientific papers is a bad idea, and we know it. Perhaps readers don’t respect scientists who resist the conventional turgidity of our writing form. I don’t think this is true, although I’m aware of no formal analysis.
Or it could be that beauty is a good idea, but well-meaning reviewers and editors squash it. In my paper I argue that beauty (like humour) can recruit readers to a paper and retain them as they read; but that reviewers and editors tend to resist its use. But again, there’s no formal analysis, so I was forced to make both halves of that argument via anecdote.
Or it could be we just don’t have a culture of appreciating, and working to produce, beauty in our writing. I think this is most of the explanation: it’s not that we are opposed to beauty as much as it doesn’t occur to us that scientific writing could aspire to it.
All of which makes me wonder: if we wanted
to make beauty more common in scientific writing, how could we do that? Well, that could make for a really long
post. I’ll mention a few thoughts,
and encourage you to leave more in the comments.
First, we could write with small touches of
beauty in our own papers. Of
course, that’s not as easy as it sounds, because most of aren’t trained or
oriented that way. To
oversimplify, it’s a chicken-and-egg problem: most of us come from science
backgrounds that lack a culture of beauty in writing. Perhaps we even came to science as refugees from the arts
and humanities where beauty is more valued. That’s true for me, at least; and I know a fair bit about
how to write functionally, but almost nothing about how to write
beautifully. But if there’s a path
to writing beauty, it probably starts in reading beauty, wherever it can be
found. Nabokov? Sure... but also
science blogs, lay essays and books about
science and nature (for a start, sample the science writing of Rachel Carson,
Lewis Thomas, Karen Olsson, Barbara Kingsolver, or John McPhee), and really,
anything we can get our hands on.
And when we read, we can be alert for language that sparkles, so as to
cultivate an ear for beauty and to build a toolbox of techniques we can deploy
in our own writing. (For some
other thoughts on this, see Helen Sword’s book “Stylish
Academic Writing”).
Second, and much easier, we could encourage
beauty in the writing of others.
As reviewers and editors, we could decide that style and beauty are not
incompatible with scientific writing.
We could resolve not to question touches of style, or unusual but
beautiful ways of writing, in the work we are judging.
Finally, we could publicly recognize beauty
when we see it. We could announce
our admiration of beautiful writing to the authors who produce it or to
colleagues who might read it. What
Jonathan and I have done with these posts is a small start on this, and I’ve
promised myself I’ll praise wonderful writing whenever I can. Thinking bigger, though, wouldn’t it be
great if there was an award for the best scientific writing of the year? I don’t mean the best science – we have
plenty of awards for that – but the best writing
to appear in our primary literature.
Such awards exist
for lay science writing; if one existed for technical writing I’d be
thrilled to make nominations and I’d volunteer to judge.
As Jonathan and I both found, examples of
beautiful scientific writing do seem to be unusual; and those that exist aren’t
well known. I don’t think it has
to be this way. W could choose to
change our culture, a little at a time, to deliver (and to value) pleasure
along with function in our scientific writing.
-----
By the way: I became interested in beauty in scientific
writing while working on a guidebook for scientific writers. It’s not available yet, but to learn
more about it, see my web site. For more of my (somewhat scattered)
thoughts on writing and on doing science, visit my
blog.

A long (and I think good) listen: Tim Ferriss podcast on "the microbiome"
So - I have been travelling a lot lately. On one of my trips - to Las Vegas and neighboring areas - I was interviewed by Tim Ferriss for his blog. Jessica Richman of uBiome was also interviewed - she was in SF, Ferriss was somewhere else, and I was on the phone in Vegas. As soon as it was over I got caught up in the work I was doing there (field work for a new NSF Funded Project on "microbial dark matter". Anyway - the interview was entertaining and I think interesting. And then it came out while I was on the road again for another trip. So I am just getting around to posting about it now. Anway - here are some links for the podcast.
Ferriss' blog post about it: Are We Really 10% Human and 90% Bacteria? Exploring The Microbiome…
Direct links
I note - I have never done such a long interview for a show before (it was about two hours) but Ferriss was remarkably adept at making it relaxing and fun (for me at least). Even the part about Jim Watson ...

UC Davis MARS Symposium Wrap Up #globalfood #UCDavisMARS
Yesterday I went to a symposium at UC Davis that was the launching of a new partnership between UC Davis and the Mars Corporation. I note - I have been collaborating with some people at Mars on multiple microbiome related projects and generally have had great interactions with the people there. I am not directly involved in the planning for this new partnership between UC Davis and Mars and thus I was interested in hearing more about it at the symposium.
The symposium was at the Mondavi Center on UC Davis campus and I zipped in on my bike through the cold (for Davis) air and got there just before they opened the doors to the main theater. I saw a few folks I knew milling around in the lobby and said hello and then went inside with some people from my lab for the "show".
I will try to write more about this later but just one note - I found some of the big picture discussions about the importance of the nexus between food, agriculture and health to be pretty inspiring. For now - I hope the Storify I made and embedded below will give some idea as to the goings on of the symposium.

Haloferax volcanii, model archaea, and me
When I was a graduate student I was looking around for an extremophile - especially an evolutionarily novel one. And I settled on this species Haloferax volcanii - a model halophilic archaeon largely because Ford Doolittle and colleagues had started to turn it into a genetic model organism (and because Patrick Keeling, from Ford's lab convinced me it was a good thing to do). So I started work on this species - doing DNA repair studies in the lab. See my PhD thesis for some of the work I did which I never published outside of the thesis for multiple reasons. But I continued to be interested in this species. And when I was working at TIGR, an NSF Program Officer approached me asking me to help get the genome sequencing done for this species. So, well, I did: The Complete Genome Sequence of Haloferax volcanii DS2, a Model Archaeon. And I became interested in other haloarchaea and eventually started working with Marc Facciotti, in the lab next to mine, in sequencing from across the diversity of the haloarchaea: Sequencing of Seven Haloarchaeal Genomes Reveals Patterns of Genomic Flux and Phylogenetically Driven Sequencing of Extremely Halophilic Archaea Reveals Strategies for Static and Dynamic Osmo-response.
Anyway - enough about me. The whole point here is to point people to a new paper: BMC Biology | Abstract | Generation of comprehensive transposon insertion mutant library for the model archaeon, Haloferax volcanii , and its use for gene discovery. Further evidence for the use of Haloferax volcanii as a model species. Tools continue to become available for genetic and experimental studies in this species. So - if you are looking for an unusual and interesting organisms to work on - consider working on this species ...

Really shameful overselling the microbiome from the American Society for Microbiology regarding lupus
Well, this press release is from October:Study Suggests Altering Gut Bacteria Might Mitigate Lupus But I just discovered it and it definitely deserves an award. An Overselling the Microbiome Award. The PR, sadly and amazingly from the American Society for Microbiology which should know better, discusses a paper from the ASM Published journal Applied and Environmental Microbiology. The PR does an OK job discussing what was in the paper - a study of the microbiome in mice including those that are a model for lupus. The researchers characterized the microbiome is mice with and without the lupus model disease and also compared over time and between sexes. And they found some interesting correlates of microbial patterns that are found during flare ups of lupus for example and also in drug induced worsening of symptoms. But they never showed ANY causal connection between any of the mcirobes and the lupus like disease. And the never showed ANY benefit of treating the lupus-like symptoms in the mice. Yet amazingly they go over board in making such claims including
In the text other statements are like this:
Also in the PR:
And then the PR ends with
This is one of the worst Press Releases I have ever seen in terms of misleading statements about microbiomes. And ASM should be embarassed about it. And ASM should retract it. And ASM should never ever put out something like this again. And for this, I am awarding a coveted "Overselling the Microbiome Award" to ASM for putting out this inappropriate press release. If any with lupus goes out and gets even remotely worse from taking such probiotics, prebiotics, or antibiotics, ASM will bear some of the responsibility for their problems. Shameful.
UPDATE 1: Jan 2, 2015
I did some searching for "probiotics" and "lupus" and found some much more tempered claims from other places. For example in "Lupus Studies Point to Gut Microbes, Epigenetics"
See also
Title: STUDY SUGGESTS ALTERING GUT BACTERIA MIGHT MITIGATE LUPUS.No - the study did not suggest that at all. The authors suggested that, yes. And the study is consistent with that. But it is also consistent with altering gut bacteria having NO EFFECT on lupus. So this title is simply deceptive.
In the text other statements are like this:
These results suggest that the gut bacteria may contribute to lupus.Stunningly, the PR includes some really inappropriate comments including:
Nonetheless, Luo suggests that people with lupus should eat Lactobacillus-containing probiotics, such as live culture yogurts, to reduce lupus flares.Seriously? Shame on ASM for allowing this garbage to be in the PR. No evidence at all is presented that this is helpful.
Also in the PR:
More generally, "The use of probiotics, prebiotics, and antibiotics has the potential to alter microbiota dysbiosis, which in turn could improve lupus symptoms," says co-principal investigator Husen Zhang. Ultimately, says Luo, fecal transplant might prove valuable as a treatment for lupus.Again, shame on ASM. No evidence is presented for this either.
And then the PR ends with
"We were inspired in part to perform this research by a study on type 1 diabetes, which found that that disease is dependent on gut microbiota," says Zhang. "Like type 1 diabetes, lupus is an autoimmune disease that is even more prevalent [than type 1 diabetes] in women."What? I know of no research that shows that type 1 diabetes is dependent on gut microbiota. I really don't even know what to say here.
This is one of the worst Press Releases I have ever seen in terms of misleading statements about microbiomes. And ASM should be embarassed about it. And ASM should retract it. And ASM should never ever put out something like this again. And for this, I am awarding a coveted "Overselling the Microbiome Award" to ASM for putting out this inappropriate press release. If any with lupus goes out and gets even remotely worse from taking such probiotics, prebiotics, or antibiotics, ASM will bear some of the responsibility for their problems. Shameful.
UPDATE 1: Jan 2, 2015
I did some searching for "probiotics" and "lupus" and found some much more tempered claims from other places. For example in "Lupus Studies Point to Gut Microbes, Epigenetics"
"The long-standing anecdotal patient reports of certain diets worsening or improving flares might be more real than we thought. They should be studied more systematically, now that we know that almost any dietary component acts on the gut microbiota, [which] in turn has profound effects on the immune system," Dr. Kriegel said. He also warned that patients should not assume that the various "probiotic" products now available to consumers would have a beneficial effect in lupus. "Probiotics could theoretically even worsen a disease state, since it is possible that physiologic immune responses against benign commensals could fuel autoimmune responses via cross-reactivity (as we hypothesize) or other mechanisms," he said.
Dr. Kriegel concluded, "I think the best will be to wait until we have a better understanding of which commensals or commensal-derived products might be driving which autoimmune disease and then target those with a diet that is known to modulate these strains or products. Ideally, the field will also develop eventually novel types of antibiotics or vaccinations against certain commensals. Such approaches would allow us, in the future, to more specifically modulate the gut microbiota in autoimmunity."Now that is responsible commenting on lupus and the microbiome. Too bad ASM allowed complete BS to get into this PR instead of more reasonaed statements.
