• Definition: 3D Printing

3D printing (also known as additive manufacturing) is any of various processes used to synthesize a three-dimensional object. In 3D printing, additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source. A 3D printer is a type of industrial robot. A longer definition comes from Wikipedia.

3D printing in the term's original sense refers to processes that sequentially deposit material onto a powder bed with inkjet printer heads. More recently, the meaning of the term has expanded to encompass a wider variety of techniques such as extrusion and sintering-based processes. Technical standards generally use the term additive manufacturing for this broader sense.

Bioprinting in 3D: Looks Like Candy, Could Regenerate Nerve Cells

Dean Reinke
Deans' Stroke Musing

Tuesday, May 12, 2015

And couldn't this be used for our needs to regenerate dead areas? What research team will figure that out? And who will provide them with the funds to do it? Bioprinting in 3D: Looks Like Candy, Could Regenerate Nerve Cells.

Tolou Shokuhfar and colleagues are developing techniques using 3D bioprinting to generate human tissue.The printer looks like a toaster oven with the front and sides removed. Its metal frame is built up around a stainless steel circle lit by an ultraviolet light. Stainless steel hydraulics and thin black tubes line the back edge, which lead to an inner, topside box made of red plastic. In front, the metal is etched with the red Bio Bot logo. All together, the gray metal frame is small enough to fit on top of an old-fashioned school desk, but nothing about this 3D printer is old school. In fact, the tissue-printing machine is more like a sci-fi future in the flesh—and it has very real medical applications.

Frustration and Stroke Survivors: 5 Ways to Avoid It

Joyce Hoffman
The Tales of a Stroke Patient

Nov 8, 2015

Charles M. Schulz is gone now (he died in 2000), but his memory lives on in the characters he created in Peanuts, those lovable little ones who express honesty to a fault, sarcasm to the weak-minded, and the thoughts by illustration of that endearing dog, Snoopy.

In one scene, Linus is obsessed that there is a Great Pumpkin who will appear on Halloween night and has Sally accompany him to the pumpkin patch. Linus passes out as  the shadow of Snoopy appears instead, rising slowly from the pumpkin patch. When Linus "comes to," Sally, out of frustration, goes into a maniacal rant about missing Halloween and all the candy. That's when she says, twice, "You blockhead!" (https://www.youtube.com/watch?v=7ushQ_mMSqw)

I called people blockheads, too, before my stroke 6 years ago. Blockhead was sometimes followed by "Aaaargh!" But that's all. Now, that I don't have any filters after my stroke (http://stroketales.blogspot.com/2014/06/impulses-and-brain-aka-fuck-where-did.html), my words are a lot worse, like prick, shithead, and asshole. If what they did was really bad, I would say, "Fuck you" (but that only happened three times and in the first year after. I ended up feeling sorry for them).

An Essential Ingredient in Better Speaking: Aphasia

Mark A. Ittleman
The Teaching of Talking

November 11 / 2015

Have you ever had one of the aha moments when you realized something you had already known, but just was not that consciously aware of it?

I just realized that yes, The Teaching of Talking Method is about helping a loved one or client speak better, and yes about the conversation, and yes, that it is free flowing and that it does follow a specific sequence of methods for those with aphasia and difficulty speaking.

It is all that but I now realize that The Teaching of Talking is about a relationship.  A relationship is necessary for it to work.  It is about two people who very much want something.  They want an outcome, a result.  But a relationship must be there for anything to work.  You could have the best method in the world to create a widget, but without the relationship the creation and fulfillment of that product would be in question.

An Amazing Stroke Survivor Narrative

Leslie
Living After Stroke

Since I started year 4 of fighting stroke deficits, I’ve been overdoing it.  This weekend I took a forced break (my body said “no more” and shut down).  I spent the time in bed reading a stroke survivor book.

You just have to read this book, it is by far the best book written by a stroke survivor.

This is not the typical, I fought my way back, I work, I run, I fully recovered, and life is great, type of story. By the way, only 10% of stroke survivors can tell that story. Please don’t compare yourself to those survivors.

They did work their asses off and I applaud them but almost every survivor works their asses off, 90% of them, without those results. The ones who fully recover had a bit of luck on their sides too.

The Zipping Challenge is Not What You Think

Rebecca Dutton
Home After a Stroke

November 4, 2015

Now that it is cold I need to zip my coat.  Velcro closures on my raincoat do not keep me warm.  When I sit, gaps form between the Velcro tabs which lets body heat escape.  I was surprised to learn the hardest part of zipping a coat is not grabbing the zipper tab.  The step that requires the most precise finger control is holding the bottom of the coat.  The 2nd photo below shows I am holding the bottom of the coat with three fingers in a 3-jaw chuck grasp.

Holding the bottom of a coat has to accomplish two things.  First, my bottom finger is keeping the joined tab and the zipper perfectly aligned.  ONLY IF you accomplish the 1st step do you get to proceed to the 2nd step which is holding the bottom of the coat still as the other hand pulls up the zipper tab.  Having a stroke does not stop zippers from being cantankerous.

On the Table: Re-coordination

Marcelle Greene
Up Stroke

Friday, November 6, 2015

Sometimes Eric and I spend our sessions in the massage room. I lie on my back and he circles the table, moving each of my body parts into its correct position.  He does this over and over again – jostling, rotating and pressing me into proper alignment.

The sessions are relaxing, but I don’t just lie there: I’m an active participant, paying close attention to where he shifts my body. He’s constantly correcting the rise of my shoulder, the tuck of my chin, the tilt of my hips. My job is to learn to assume these positions myself.

I focus on the position he leaves me in as he moves onto another part of my body. When he reaches my spastic arm or leg, my torso often contorts: on the healthy side, my ribs bulge, my back arches. This compensation for my affected limbs is particularly noticeable on the table where I feel the absence of the supportive pressure beneath my back.

Emotions Aren't Scary

Beth Sinfield
Beth's Story

Friday, 6 November 2015

I thought I'd write a blog post on the emotional changes after stroke. They can be hidden and very hard to understand. If you're maybe over emotional (like me) people will just assume you're depressed. Which is not the case. At all. People don't see the emotional side so when you are emotional or anxious, people don't understand and unfortunately, they judge. It is 100% normal to have emotional changes after stroke or brain injury, it is very common but we still don't like to talk about it that much.

Ok, I'll be open with you, I suffer with emotional lability and anxiety. I see them as the worst combination of emotional problems sometimes. Emotional Lability (or Pseudobulbar effect- PBA), as defined by good old wikipedia, is 'a neurological disorder characterised by involuntary crying or uncontrollable episodes of crying/laughter.' Now people looking at this will think 'omg' or they might even think that I'm a complete weirdo who's emotionally unstable but I can tell you now that it's not like how it is characterised. I never experience uncontrollable outbursts of crying or laughter. My emotional lability is characterised by, kinda, 'over-the-top happiness' so basically I'm a very smiley, happy person. If you ask anyone, the first thing they'll say is that I smile a lot. Even when I'm angry or upset I will smile, I try not to make it seem deadly serious sometimes, that helps a lot. When I get angry I may giggle uncontrollably sometimes or I may cry; I always say that my brain makes it come out wrong. People then think that I'm upset but I'm really not. Trust me. So it's not awful, right?

Day 9 Attitude of Gratitude Journal

Diana Smith
Beyond Reality

November 9, 2015

Today I am thankful for collectors. If it was not for the people that value the material objects I sell online, I would not have as much fun. The money I make from selling my vintage wares is what funds my nights out, my extra tank of gas, my fast food for my son so I have a few extra minutes to rest or get ready.

I am also learning by researching the random stuff I buy in box lots, or that I buy because it catches my eye and seems like I can multiply my investment 10 times. I sometimes take an hour or two on google reading specific websites I would otherwise not go to. I also learn the lesson of to never buy that type of item again, like the time I bought a super heavy typewriter I could barely carry, much less pack to ship with one hand. I have also sworn off glass, although I have still picked up a mug or small ashtray, gambling with my 10 cents.

Indirectly, because of the collectors, I am learning to push myself. I get out to the post office more often. I take quick trips for more packing tape. These types of things cut into my small profit, but without doing them I would be sitting on the uncomfortable couch all the time. I am also learning to let go of “items”, just because I have had them for years or thought I liked acquiring pretty things. I no longer wish to clutter my life with excess. I am on the long slow road to simplify. It helps my brain sort itself out.

Hole in the Heart - Patching or not Patching?

Jeff Porter
Stroke of Faith

Tuesday, October 27, 2015

My own stroke was blamed on a hole in my heart - a patent foramen ovale, or an opening between the two upper chambers of the heart. The opening was closed in 2007. To read more about that, you can follow this link.

Researchers have been back and forth on whether closing the hole is a good idea or not. The most recent discussion made more sense - to this layman - and how for some, the closure makes sense. For others, not as much.

For example, relatively young people with a combination of the hole and an atrial septal aneurysm - that's when the wall between the two upper chambers of the heart is bulging - might benefit more. That was my case.

So follow this link to read more about the results of PFO closure in the long term:

While patent foramen ovale (PFO) closure still doesn't pan out for overall outcomes in long-term follow-up, the procedure does what it is supposed to in terms of reducing recurrent cryptogenic strokes, particularly for younger adults, the RESPECT trial showed.

50 Shades of Food

Sas Freeman

November 2, 2015

Now that we are into the shorter winter days and the damp chill in the air, many of us, myself included, find we have to be more careful with our health. Simply having a flu jab isn’t sufficient protection against winter colds and bugs, chest infections and the like. Often, also if we are fighting off one of these when we go along for a flu vaccination we find that it exaggerates the symptoms and we become unwell for sometime afterwards.

So what is the remedy? Obviously not being medical I cannot quote some magical answer but, I can speak from experience. Having now had several winters of ill health, pericarditis mainly, I went into this autumn fully armed as it were. I am not naive enough to say I have found the solution and I will definitely remain fit and healthy all winter, although obviously it is my wish and aim, but so far I have definitely improved on this time last year.

Food

My secret, is my simple kitchen cupboard contents. I touch on these in my book so some of you will think it’s what you have already read but often we need reminding, why had I forgotten some of them?

By making a few changes and additions to our daily diet. My main one, my body was actually craving for, a simple nut, almonds. I have been eating these by the handful each time I have felt peckish. This craving has calmed down now and I eat them still daily but fewer per day. They are a super food packed with goodness, so much so having had my results last week my cholesterol and blood sugar both were dramatically reduced, my kidney & liver function improved too. If bought in small packets they are expensive but the new ‘kid on the block’, Aldi/Lidl sell them loose which is far better value. Don’t ever eat them blanched though, unless in cooking, as they are too difficult for the kidneys to break down.

What a Long, Strange Trip it’s Been

Barb Polan
Barb's Recovery

November 3 / 2015

I just looked at a video clip on FaceBook – an interview with Travis Roy. (Thank you, Kathy T, for posting that.) Everyone of a certain age in the Boston area remembers Travis Roy – the NHL-hopeful at Boston University). Eleven seconds into the first game he ever played at BU, he was slammed into the boards and paralyzed from the neck down. Last week was the 20th anniversary of his injury; the news angle was that he was honored for his work raising money for a foundation that supports spinal cord injury research.

“It’s been quite a trip,” he said about the 20 years since his future changed abruptly when he was 20 years old.

“Quite a trip?” was my immediate thought.  Yes, just the reaction of the survivors of the Titanic, right?

It made me look, though, at my own “trip”: recovery from a disabling stroke 6 years ago, at 52. Travis was young, with his promising future blasted apart; while I was established, and my modest expectations were blown away. We both ended up experiencing lives that were not what either of us were “supposed” to have. Previously, I have called my experiences a “pilgrimage,” a trip with a holy destination, but the word implies a trek, something difficult.

Looking at his journey as “quite a trip,” Travis put a positive spin on an unenviable situation: the opportunity to use his story and fame to establish a way of helping other patients with injured spinal cords, his tribe.

Brain Imaging in Diagnosis of Lewy Body Dementia

insula implicated in DLB

Recent information has emerged concerning the suicide death of the comedian/actor Robin Williams.

Autopsy results have demonstrated that Robin Williams suffered from dementia with Lewy bodies (DLB).

This public case demonstrates the difficulty in making a correct diagnosis of DLB prior to the findings at autopsy.

In a previous post I reported on a screening tool for clinicians that appears to have some promise for screening for high-risk DLB patients.

In this post, I want to follow up on this topic by reviewing a recent brain imaging study that targeted patterns of brain cortical thinning in the dementias.

The key elements in the design of this research study included the following elements:

• Subjects: 28 subjects with prodromal DLB, 27 subjects with prodromal Alzheimer's disease (AD), 31 subjects with DLB, 54 subjects with AD and cognitively normal elderly adults.
• Brain Imaging: Structural magnetic resonance imaging (MRI) with a 3 Tesla scanner
• Statistical Analysis: FreeSurfer analysis of regional cortical thickness pattern across diagnosis groups

Ultrasonic Waves Transform Cold Water into Powerful Cleaning Agent

November 6 / 2015

Scientists from the department of Engineering and the Environment at the University of Southampton have created a device called Starstream that is capable of transforming cold water into an industrial-strength cleaning solution. The only elements added to the water are tiny air bubbles and ultrasonic waves. These additions allow the water to penetrate deep into every crevice of almost any surface. Researchers believe just six seconds of washing with Starstream is equivalent to 20 seconds of washing vigorously with soap and water.

The device’s creators, Professor Tim Leighton and Dr. Peter Birkin, hope this technology will help combat antibiotic and antimicrobial resistance by removing chemical agents from many sanitization processes used in the healthcare industry. The grand vision is to find a way to incorporate the technology into the hand-washing routines of every person on Earth. This would greatly reduce the ability of microbes to enter the body via contaminated hands.
