Links for Tuesday, November 21, 2017: more on the new HTN guideline, Gymnastics coaches throwing robot shade, the last iron lungs, Germany bans smartwatches, and Raymond Chandler hated US healthcare

Thoughtful post on the new HTN guideline by Dr. Allen Brett

Representative quote: "Consider, for example, a healthy white 65-year-old male nonsmoker with a BP of 130/80 mm Hg, total cholesterol level of 160 mg/dL, HDL cholesterol of 60 mg/dL, LDL cholesterol of 80 mg/dL, and fasting blood glucose of 80 mg/dL — all favorable numbers. The calculator estimates his 10-year CV risk to be 10.1%, making him eligible for BP-lowering medication under the new guideline. To my knowledge, no compelling evidence exists to support drug therapy for this person."

A gymnastics coach says the Boston Dynamics robot flip was a 3.5/5.0

'In a back salto, says Mazloum, “you want to be able to go as high as you can, and you want to be able to land as close to where you take off as possible.” To do that, the gymnast has to squat, throw her arms up by her ears so her body is a straight line (in gymnast-speak, opening the shoulder angle and the hip), then contract into a “closed” position again. By these standards, Atlas’ trick is “not the cleanest flip,” explains Mazloum.

Here’s Mazloum’s critique: Atlas didn’t quite get to that open position, “so it didn’t really get the full vertical that we look for. That’s why it went backwards a little bit.”'

The last of the iron lungs

Get your kids vaccinated for polio, folks.

Germany has banned smartwatches for kids

If I understand this correctly, it is not because smartwatches cause kids to be distracted monsters (although I don't doubt that that statement is at least a little bit true). The decision stems from the capability of bad guys to hack in and monitor the location of little Dick and Jane:

You have to wonder who thought attaching a low-cost, internet-enabled microphone and a GPS tracker to a kid would be a good idea in the first place. Almost none of the companies offering these “toys” implement reasonable security standards, nor do they typically promise that the data they collect—from your children—won’t be used be used for marketing purposes. If there ever was a time to actually sit down and read the terms and conditions, this was it.
Get your shit together, parents.

Asking parents to destroy them might be a bit of an overreaction, though.

Raymond Chandler paints a dark picture of American healthcare in a newly-discovered story

The title, "It’s All Right – He Only Died," sounds like the title of a video residencies would show interns to convince them that quality improvement and patient safety are part of their job.

The doctor who turned away the patient, Chandler writes, had “disgrace[d] himself as a person, as a healer, as a saviour of life, as a man required by his profession never to turn aside from anyone his long-acquired skill might help or save”.

 

Links for Tuesday, November 7, 2017: hacking the genome, ammonia in the NFL, and community health workers for hypertension

Body hacker Josiah Zayner wants us all to use CRISPR to modify our bodies

And give ourselves cancer. I think he forgot the cancer part. From author Rowan Jacobsen:

"Let’s be clear: don’t try this at home! Although hundreds of gene-therapy trials are under way, and many experts believe they will eventually transform almost every aspect of human health, few have been proven safe. When you start scrambling your DNA, very bad things can happen. You can get cancer. Your immune system can attack the unfamiliar DNA, as happened when an 18-year-old with a rare metabolic disorder died during a University of Pennsylvania gene-therapy trial in 1999."

You may recall a link I posted to this guy giving himself a DIY fecal transplant. I'll give him an A+ for marketing. You can't beat the name Gut Hack:

NFL players have decided (not recently, it seems) that inhaling ammonia is performance-enhancing

Instead of something sinister, though, what the widespread use of smelling salts really reveals is the increasingly bizarre culture created by the NFL's (win-at-all-costs pressure cooker. Extreme parity, the minuscule margin of error, the constant threat of injury and million-dollar stakes all push players to exploit any shortcut, no matter how weird, gross or pitiful. More than a century ago in major league baseball, players like Hall of Fame pitcher Pud Galvin thought consuming ground-up monkey testicles was the answer (seriously). A decade ago, football found deer antler spray. Now it's smelling salts.

Not coke, but smelling salts in a cup. I think I would actually prefer ground-up monkey testicles.

More evidence that community health workers improve the care of certain patient populations

(paywall, but the abstract is free)

The proportion of patients with controlled hypertension increased from 17.0% at baseline to 72.9% at 18 months in the intervention group and from 17.6% to 52.2% in the usual care group; the difference in the increase was 20.6% (95% CI, 15.4%-25.9%; P < .001).
