Here is a tweetorial from our latest publication in @Annals_Oncology about longitudinal tracking of esophageal adenocarcinoma. #OesophagealCancer #EsophagealCancer https://t.co/QWvrzBXmK7 1/8

We sequenced 245 plasma samples from 97 patients with oesophageal adenocarcinoma using a 77 gene pan-cancer ctDNA panel. 2/8
Variants derived from previously characterised driver oesophageal adenocarcinoma genes had a significantly higher VAF than variants from other genes, indicating selection. 3/8
Peripheral blood cell samples were also sequenced for 78/97 patients. CHIP mutations were identified in 23% of cases, longitudinal tracking of CHIP variants suggested these variants were dynamic over time. 4/8
We found patients that were ctDNA positive post-surgery had a significantly poorer survival than ctDNA negative patients, and the elimination of CHIP variants improved the positive predictive value. 5/8
In summary, we demonstrate in a large, national, prospectively-collected dataset that ctDNA in plasma following surgery for EAC is prognostic for relapse. Inclusion of peripheral blood cell samples can reduce or eliminate false positives from CHIP. 6/8
In the future, post-operative ctDNA could be used to risk stratify patients into high- and low-risk groups for intensification or de-escalation of adjuvant chemotherapy. 7/8
Many thanks to our founders and all patients who participated within the OCCAMS consortium framework. The study was carried out by our brilliant PhD student Emma Ococks, medical oncologist @LizzySmyth1, postdoc @AFrankell, and postdoc @neus_snows among others @MRC_CU. 8/8

this simple, counter narrative fact keeps cropping up all over the world.

hospital and ICU utilization has been and remains low this year.

it's terribly curious that so few of these monitoring tools provide historical baselines.

getting them is like pulling teeth.


we might think of this as an oversight until you see stuff like this:

this woman was arrested for filming and sharing the fact that their are empty hospitals in the UK.

that's full blown soviet. what possible honest purpose does that

this is the action of a police state and a propaganda ministry, not a well intentioned government and a public heath agency.

"we cannot let people see the truth for fear they might base their actions on real facts" is not much of a mantra for just governance.


90% full ICU sounds scary until you realize that 90-100% full is normal in flu season.

staffed ICU beds are expensive to leave empty. it's like flying with 15% of the plane empty. hospitals don't do that.

and all US hospitals are mandated to be able to flex to 120% ICU.

the US is currently at historically low ICU utilization for this time of year.

61% is "you're all going to go out of business" territory as is 66% full hospital use.

can you blame them for mining CARES act money? they'll die without it.
No-regret #hydrogen:
Charting early steps for H₂ infrastructure in Europe.

👉Summary of conclusions of a new study by @AgoraEW @AFRY_global @Ma_Deutsch @gnievchenko (1/17)
https://t.co/YA50FA57Em


The idea behind this study is that future hydrogen demand is highly uncertain and we don’t want to spend tens of billions of euros to repurpose a network which won’t be needed. For instance, hydrogen in ground transport is a hotly debated topic
https://t.co/RlnqDYVzpr (2/17)

Similar things can be said about heat. 40% of today’s industrial natural gas use in the EU goes to heat below 100°C and therefore is within range of electric heat pumps – whose performance factors far exceed 100%. (3/17)


Even for higher temperatures, a range of power-to-heat (PtH) options can be more energy-efficient than hydrogen and should be considered first. Available PtH technologies can cover all temperature levels needed in industrial production (e.g. electric arc furnace: 3500°C). (4/17)


In our view, hydrogen use for feedstock and chemical reactions is the only inescapable source of industrial hydrogen demand in Europe that does not lend itself to electrification. Examples include ammonia, steel, and petrochemical industries. (5/17)
I think @SamAdlerBell in his quest to be the contrarian on Fauci gets several things wrong here. 1/


First, the failure last year actually was driven by the White House, the #Trump inner circle. Watch what's happening now, the US' scientific and public health infrastructure is creaking back to life. 2/

I think Sam underestimates the decimation of many of our health agencies over the past four years and the establishment of ideological control over them during the pandemic. 3/

I also am puzzled why Tony gets the blame for not speaking up, etc. Robert Redfield, Brett Giroir, Deb Birx, Jerome Adams, Alex Azar all could have done the same. 4/

Several of these people Bob Redfield, Brett Giroir, Alex Azar were led by craven ambition, Jerome Adams by cowardice, but I do think Deb Birx and Tony tried as institutionalists, insiders to make a difference. 5/
