Sweating blood? It happens — and not only on Halloween

Here’s this week’s round-up of heterogeneous and under-the-radar health and medical scholarship news. If we haven’t subscribed yet, we can do that by clicking here.

Halloween got a tiny weirder this year with news that some people can indeed persperate blood. At initial there was usually one case, detected by doctors in Florence, Italy, published in a CMAJ on Monday. But given afterwards some-more cases of sweating blood have been reported to Jacalyn Duffin, a Canadian historian and hematologist, who searched the medical literature for references to this weird condition.

‘It seems that humans do persperate blood, despite distant reduction mostly literally than metaphorically.’
– Jacalyn Duffin, medical historian, Queen’s University

When a Italian physicians initial encountered a 21-year-old lady who seemed to persperate blood, they insincere she was faking a condition. But afterwards they diagnosed her with hematohidrosis, a singular illness characterized by a “spontaneous liberate of ‘blood sweat’ through total skin,” nonetheless they still don’t know what causes it or how a blood ends adult flitting by a skin like sweat.

The shocking picture of a unclear woman’s blood-dripping face triggered a media frenzy, causing a CMAJ to temporarily dump a paywall.

Duffin is intrigued by that reaction. She searched behind by a medical novel and found reports about sweating blood that antiquated behind to a third century BC.

“It seems that humans do persperate blood, despite distant reduction mostly literally than metaphorically,” she wrote in a commentary concomitant a medical report.

Even yet a novel indicates it’s been duty via tellurian history, Duffin records that there is a hostility to trust in sweating blood, presumably since of a organisation with “religious mystery.”

“Other singular conditions are not beheld with identical skepticism,” she wrote. “Ironically, for an increasingly physical world, a long-standing organisation of hematohidrosis with eremite poser competence make a existence harder to accept.”

Since Monday, Duffin has been contacted by 5 people who contend they’ve gifted a bizarre occurrence of sweating blood.  Now she’s operative with a blood coagulation consultant and a dermatologist to serve examine this confusing condition.

Why meditative about zero is a good thing

Ever been told to stop daydreaming? A new investigate suggests mind erratic — or in neuroscience-speak, carrying “task-unrelated thoughts” — competence be a pointer of a higher brain.

“It competence not be as inherently disastrous as we have been meditative of it to be and there competence indeed be some certain attributes compared with mind wandering,” pronounced Christine Godwin during a Georgia Institute of Technology, lead author of a paper published recently in a biography Neuropsychologia.

‘Their smarts duty some-more good and they have additional ability to say opening on easy tasks.’

Godwin examined a mind activity of some-more than 100 people who remained watchful yet meditative of zero in particular. The measurements were conducted regulating a organic captivating inflection imaging (fMRI) scanner — a appurtenance that measures mind activity by detecting changes in blood flow. When Godwin compared a mind scans to other tests, she resolved that daydreamers were some-more artistic and intelligent.

Godwin’s speculation is that someone who is daydreaming in a center of a charge or a assembly is indeed demonstrating that they have a mental coherence to listen with “half an ear” and still know what’s going on in a room.

“Their smarts duty some-more good and they have additional ability to say opening on easy tasks and also vouchsafing themselves cruise about other things that seductiveness them as well,” Godwin said.

Godwin’s investigate is partial of an bid by scientists to find out what’s unequivocally going on in a mind when a chairman appears to be doing zero yet staring into space.

Increasingly investigate is focusing on an intriguing neural network called a “default mode,” detected in a early 2000s after scientists beheld unexplained mind activity during fMRI scans even yet subjects were usually daydreaming.

It’s been shown that the default mode network is altered by a operation of opposite neurological disorders including Alzheimer’s and autism, yet so distant no one has been means to explain because it is influenced or what accurately it does.

One organisation during a University of Cambridge published some results this week suggesting a default mode network is concerned when we switch to autopilot while we’re doing informed tasks.

‘The deduction is that, indeed, we competence good be stranded in your memories and over-thinking and over-analyzing.’ 
-Dr. Emmanuel Stamatakis, University of Cambridge

“It’s an area in a center of a mind that is really good connected to all other tools of a mind so it has entrance to your memory so it can do a lot of opposite and useful things, one of that is this autopilot role,” pronounced Dr. Emmanuel Stamatakis during a University Of Cambridge.

The researchers trust a default network helps a mind make quick decisions during informed tasks. It competence explain that prodigy of not being totally wakeful of what you’re doing while pushing a informed route, for example.

The network has also been related to basin and scientists suppose that some people have difficulty relocating out of a default mode.

“The deduction is that indeed we competence good be stranded in your memories and overthinking and overanalyzing and we don’t take as most cueing from a outmost world,” pronounced Stamatakis.

Robotic-assisted medicine costs more — and takes longer

First came laparoscopic medicine — techniques permitting surgeons to use churned tiny incisions rather than creation a large cut — and afterwards came a robots, where laparoscopic instruments are robotically operated and remotely tranquil by a surgeon.

The robotic-assisted techniques have been widely adopted, yet how are they doing? Research published this week in JAMA gave robotic operations churned reviews. The authors evaluated some-more than 23,000 patients who underwent kidney dismissal surgeries — famous as nephrectomies —  in 416 U.S. hospitals between 2003 and 2015.

About 20 per cent of a subjects had robotic-assisted procedures, while a rest had unchanging laparoscopic surgeries conducted usually by a surgeons themselves.

The good news is that there were no poignant complications compared with a increasingly common robotic procedures.

The not-so-great news is that a robot-assisted kidney operations took longer, and as a result, cost some-more in operating-room time and supplies.
