Finding a talisman

~ Simon ~ 10 Comments

# # # #

Experiential observations and anecdotal insights from the patient community have generated many key discoveries for the field of Parkinson’s research. A chance question (“Why do people with Parkinson’s smell different?” – click here to read more about that) or random interaction have opened doors to entirely new realms of research.

An good example of this are numerous reports of symptomatic relief at high altitudes. Some people with Parkinson’s find that when they are above a certain altitude, they are almost symptom free.

The mechanism of this phenomenon is unknown, but a new study in the Netherlands is hoping to help us better understand it.

In today’s post, we will discuss the Talisman study.

The Kingdom of Bhutan is a landlocked nation of 755,000 people in the Eastern Himalayas. It is embedded in the mountainous region between China and India, and it is one of the highest countries in the world – sitting at an average land elevation of 10,760 feet above sea level (Source).

Interesting facts about Bhutan (Source):

  1. Bhutan was the first country in the world to have specific constitutional obligations on its people to protect the environment. Among the requirements, at least 60% of the nation must remain under forest cover at all times.
  2. One-third of Bhutan’s population is under the age of 14 (its median age is 22.3 years).
  3. It is the only nation in the world where the sale of tobacco is completely banned.
  4. The capital (and largest) city, Thimpu (pop.: 114, 551), does not have a single traffic light.
  5. It was one of the last countries in the world to introduce television. The government lifted a ban on TV—and on the Internet—in 1999.

Interesting, but what does any of this have to do with Parkinson’s?

At the end of each month the SoPD writes a post which provides an overview of some of the major pieces of Parkinson’s-related research that were made available during May 2022.

The post is divided into 10 parts based on the type of research:

# # # #

So, what happened during May 2022?

In world news:

May 6th – The 2022 monkeypox outbreak began when the first case was reported in London (United Kingdom).

 

May 12th – The Event Horizon Telescope collaboration revealed its first image of Sagittarius A*, a supermassive black hole at the centre of the Milky Way.

 

May 12th – Researchers announced that they were able to grow plants in soil samples from the moon collected by the Apollo astronauts in the 1970s (Click here to read more about this).

 

May 17th – Angel Alvarado (aged 19) set a new world record of four and a half minutes — breaking his own record by 20 seconds – for solving three Rubik’s Cubes at the same time while juggling them:

 

May 24th – I don’t care what anyone says, school shootings really upsets me – and this only happens in the USA (the length of the Wikipedia page on US school shooting statistics truly defies belief – it is utterly incomprehensible – but the fact that nothing is going to change in the wake of the latest tragic situation is the part that is really shameful).

 

May 25th – Engineers present a submillimeter-scale multimaterial remote-controlled walking robot. At only a half-millimeter wide, these tiny ‘crabs’ can bend, twist, crawl, walk, turn and even jump (Click here to read their report and click here to read the press summary).

 

In the world of Parkinson’s research, a great deal of new research and news was reported:

In May 2022, there were 825 research articles added to the Pubmed website with the tag word “Parkinson’s” attached (5,345 for all of 2022 so far). In addition, there was a wave to news reports regarding various other bits of Parkinson’s research activity (clinical trials, etc).

Oh, you sweet thing

~ Simon ~ 2 Comments

# # # #

Sugar provides an easy and immediate source of energy for our bodies. It also helps to make things taste good, and we probably eat too much of it as a result.

Recently researchers have reported a curious association between Parkinson’s and sugar: People with Parkinson’s consume more sugar

In today’s post, we will review some of this new research and speculate on the potential implications of the findings.

# # # #

Today’s post needs music and the video above feels appropriate.

I have a rather sweet tooth.

In fact, if we are being completely honest: I am definitely addicted to sugar.

It started young for me Source: Mamanatural

On any given day of the week, in the late afternoon, my brain will begin screaming at me to start the mass consumption of sugar. On good days, a single chocolate cookie can satisfy the urge. On a bad day, however,… well, let’s not talk about the bad days…

An example of my bad days. Source: Madefromchocolate

Several years ago I tried a week of no processed sugar.

It was harder than you think, because sugar is basically in everything we eat in the modern western world. And I mean everything.

Source: Youtube

But I was really shocked that on day two of my little experiment, I was having what felt like withdrawal symptoms in the late afternoon when my brain began “screaming at me to start the mass consumption of sugar“.

It was a real struggle to get through the week, but I made it. And to reward myself,… I had… a piece of… my favourite chocolate cake.

And I was shocked at how sugary it tasted! Sickly sweet.

But it didn’t take me long to get back into my bad old habits. 2 or 3 days perhaps.

We eat way too much sugar in western society and we could all do very well by eating a lot less of it (Source). And now recent research points towards people with Parkinson’s having a higher level of sugar intake.

What?!?

Oh dear: Dairy?

~ Simon ~ 2 Comments

# # # #

Dairy-based products make up a significant portion of the world’s diet and represent a fundamental component of most western cuisine.

Previous research has, however, pointed towards an association between consumption of dairy and risk of Parkinson’s.

New research provides further support for this connection.

In today’s post, we will look at the mysterious bond between dairy intake and Parkinson’s.

Me and Brie. Source: Wikipedia

When I turned 25, I realised that my body no longer accepted cheese.

This represented a very serious problem for me.

You see, I still really loved cheese. A bottle of red wine, a baguette and a chunk of brie – is there any better combination in life?

Heaven. Source: Healthylivingpc

My body and I had a really bad falling out about this. And yes, it got ugly. I wanted things to keep going the way they had always been, so I tried to spice things up by introducing new and exotic kinds of cheeses, which my body didn’t want to know about it. It rejected all of my efforts. And after a while, I gradually started resenting my body for not letting me be who I was.

We sought help. We tried some interventions. But sadly, nothing worked.

And then things got really bad: My body decided that it didn’t have room in my life for yogurt, milk or even ice cream anymore (not even ice cream!!!).

Basically no dairy what so ever.

There’s something’s missing in my life. Source: Morellisices

OMG! How did you survive without ice cream?

Well, I’ll tell ye – it’s been rough.

All silliness aside though, here is what I know: It is actually very common to develop a lactase deficiency as we age – lactase being the enzyme responsible for the digestion of whole milk. In fact, about 65% of the global population has a reduced ability to digest lactose after infancy (Source: NIH – more on this in a moment).

I am not lactose intolerant (one of the few tests that I actually aced in my life), but I do have trouble digesting a particular component of dairy products – which can result in discomfort… and let’s just say socially embarrassing situations (one day over a drink I’ll tell you the ‘summer afternoon cheese fondue story’).

If one is forced to drop a particular food group, dairy is not too bad (but if I am ever forced to give up wine, I swear I’ll go postal).

And some new Parkinson’s-related research has indicated that more of us should possibly be avoiding dairy.

What is the new research?

At the end of each month the SoPD writes a post which provides an overview of some of the major pieces of Parkinson’s-related research that were made available during April 2022.

The post is divided into 10 parts based on the type of research:

# # # #

So, what happened during April 2022?

In world news:

April 4th – The Intergovernmental Panel on Climate Change (IPCC) released the third and final part of its Sixth Assessment Report on climate change, warning that greenhouse gas emissions must peak by 2025 at the latest and decline 43% by 2030, in order to limit global warming to 1.5 °C (2.7 °F).

 

April 14th – Ignominious stuff: The Russian Black Sea Fleet flagship Moskva became the largest warship to be sunk in action since World War II.

 

April 22nd – The Large Hadron Collider recommenced full operations, three years after being shut down for upgrades.

April 25th – The social media network Twitter accepted a buyout offer from Tesla and SpaceX CEO Elon Musk for $44 billion (that amount would fund a lot of Parkinson’s research and community nurses… just saying…)

In the world of Parkinson’s research, a great deal of new research and news was reported:

In April 2022, there were 1006 research articles added to the Pubmed website with the tag word “Parkinson’s” attached (4418 for all of 2022 so far). In addition, there was a wave to news reports regarding various other bits of Parkinson’s research activity (clinical trials, etc).

Breathtaking research

~ Simon ~ 2 Comments

# # # #

Breathing is one of those many aspects of life that we all take completely for granted for the vast majority of our time on planet Earth.

It represents not only a magnificent means of providing our bodies with oxygen, but also disposing of waste.

Recently researchers have attempted to see if there are any components in the waste part of our exhaled breath that could be useful in terms of diagnosing, stratifying and monitoring Parkinson’s.

In today’s post, we will discuss what breath is made up of, what this new research found, and explore what the potential implications of the findings are.

“Breath is the finest gift of nature. Be grateful for this wonderful gift.”
― Amit Ray

On any given day, the average person takes 17,000 breaths (the normal rate for an adult at rest is 12 to 20 breaths per minute).

When we breath in, the inhaled air – made up of approximately 16% oxygen, 4% carbon dioxide, and 79% nitrogen – is taken down to a pair of organs we know of as the lungs. Most of us have two lungs, but they are not exactly alike. The lung on the left side of your body is divided into two lobes, while the lung on your right side is divided into three. And the left lung is also slightly smaller, making room for your heart.

Combined, your lungs contain approximately 2,400 kilometres (1,500 miles) of airways and 300 to 500 million air sacs (called alveoli – Source). Through the thin walls of the alveoli, oxygen from the inhaled air passes into your blood in the surrounding capillaries. At the same time that this is occurring, carbon dioxide moves from your blood and out into the air sacs.

When you breathe out (exhale), your diaphragm and rib muscles relax, reducing the space in your chest. As the chest cavity gets smaller, your deflating lungs push the carbon dioxide-rich air up your windpipe and then out of your nose or mouth.

Exhaled air consists of 78% nitrogen, 16% oxygen, and 4% carbon dioxide. In addition to this, there are also trace amounts of “other stuff”.

And it’s that “other stuff”, where our post starts today.

Ok, I’ll bite: What do you mean by “other stuff”?

A rising tide with liraglutide

~ Simon ~ 6 Comments

# # # #

A class of diabetes drugs called GLP-1 receptor agonists have exhibited neuroprotective properties in models of Parkinson’s, and a Phase IIb clinical trial produced encouraging.

This research has led to a number of parties to start investigating new and old GLP-1 receptor agonists for their potential to slow the progression of Parkinson’s.

Recently, the results of a second Phase II clinical trial investigating a GLP-1 agonist were announced. The agonist being tested was liraglutide. 

In today’s post, we will discuss what GLP-1 receptor agonists are, what research has been conducted in PD, and look at the recent clinical trial announcement.

The name “Golden Goose Award” doesn’t really conjure images of an inspirational kind of accomplishment. It does not suggest the same kind of gravitas that the Nobel prize carries. 

In fact, it sounds rather comical: The golden goose award? Sounds like a children’s book writers award.

 And yet…

The Award was originally established in 2012 with the goal of celebrating researchers whose seemingly odd or obscure federally funded research turned out to have a significant and positive impact on society as a whole.

And despite the name, it is a very serious award – past Nobel prize winners (such as Roger Tsien, David H. Hubel, and Torsten N. Wiesel) are among the awardees.

In 2013, it was awarded to Dr John Eng, an endocrinologist from the Bronx VA Hospital.

Be one with Vitamin B1

~ Simon ~ 15 Comments

 

 

# # # #

BEFORE WE START: There are some topics that I am reluctant to address on this website, because there are folks within the community who have extremely vested interests in them. Thiamine (or Vitamin B1) is one of those topics. Some members of the Parkinson’s community have indicated to me that high doses of this vitamin are helping them. If you are one of those people, I say ‘Wonderful! Do what works for you”.

To stem the endless flow of emails asking for thoughts on high dose thiamine, however, I am writing this post to outline what research has been done on this topic in the Parkinson’s field. If you are looking for answers on thiamine, you may be disappointed. I am doing this to be able to point all future inquires towards it. That said, let’s begin:

In today’s post, we will delve into what thiamine (or vitamin B1) is and what it does in the body, how it relates to Parkinson’s, and we will discuss what clinical research exists for supporting its use as a treatment for PD.

The Ryūjō. Source: Wikipedia

On December 19th 1882, the Japanese Naval training ship Ryujo (“Prancing Dragon”) set sail from Shinagawa, Japan, and over the next 10 months it called in at New Zealand (yay!), Chile, and Peru.

During this routine training voyage, however, 169 members of a crew of 376 crew became very sick.

That’s almost half (45%) of the crew.

In fact, the situation on board the boat got so bad that they had to stop in Hawaii on the homeward leg, because too many of the crew were sick to continue the voyage. Sadly by the time they returned to Japan in October 1883, there were 25 less members of the crew as a result of death due to sickness (and remember this was just a training voyage).

What was the sickness?

The men were suffering from a condition called beriberi.

What is beriberi?

Beriberi comes from a Sinhalese phrase which translates to “weak, weak” or “I cannot, I cannot“. There are two forms of the condition: ‘wet’ beriberi and ‘dry’ beriberi. Wet beriberi involves a fast heart rate, shortness of breath, and leg swelling. Dry beriberi is characterised by numbness of the hands and feet, confusion, trouble moving the legs, and pain. It is often said that ‘Wet’ involves the heart and ‘Dry’ involves the brain.

Both forms of the condition, however, are caused by a deficiency in vitamin B1 – also known as thiamine.

The Llama-nation of LRRK2

~ Simon ~ Leave a comment

# # # #

Antibodies are tiny y-shaped markers used by the immune system to label foreign agents within the body. Once bound to something, antibodies can alert immune cells to come and remove the object. Antibodies can also inhibit the object from doing anything nasty, like infecting or damaging a cell.

Between species, different types of antibodies have been identified and over the last few decades, scientists have re-engineered this natural system for many different purposes, including medicinal therapy. 

Recently, researchers have developed a new type of antibody and used it to better understand the activity of a Parkinson’s-associated protein: LRRK2

In today’s post, we will discuss what antibodies are, explore some of the different types that exist, re-examine what LRRK2 is, and review the recent research report.

Her name is Winter.

And she is a brown coated llama who lives on a research farm near Ghent (Belgium), along with 130 other llamas. You have probably never heard of her, but she has been a critical component in the fight against COVID-19.

Back in 2016, scientists chose a nine-month-old “Winter” as the llama they would inject with spike proteins from SARS-CoV-1 and MERS-CoV viruses, in the hope that she would produce antibodies that could neutralize all coronaviruses.

Note the date – this is why basic research is important to fund.

Jump forward to early 2020, and some of the antibodies that Winter produced back in 2016 were tested on samples of a new coronavirus called SARS-CoV-2 (aka COVID-19). They were found to potently inhibit the virus and Winter’s antibodies appeared in a major research publication:

Title: Structural Basis for Potent Neutralization of Betacoronaviruses by Single-Domain Camelid Antibodies.
Authors: Wrapp D, De Vlieger D, Corbett KS, Torres GM, Wang N, Van Breedam W, Roose K, van Schie L; VIB-CMB COVID-19 Response Team, Hoffmann M, Pöhlmann S, Graham BS, Callewaert N, Schepens B, Saelens X, McLellan JS.

PMID: 32375025                     (This report is OPEN ACCESS if you would like to read it)

This is great, but what do llama antibodies have to do with Parkinson’s?

Monthly research review – March 2022

~ Simon ~ 1 Comment

# # # #

At the end of each month the SoPD writes a post which provides an overview of some of the major pieces of Parkinson’s-related research that were made available during March 2022.

The post is divided into 10 parts based on the type of research:

# # # #

So, what happened during March 2022?

In world news:

March 1st – It was announced that the US Patent and Trademark Office ruled that the Broad Institute of MIT and Harvard will retain their intellectual property over the use of CRISPR-Cas9 gene editing in eukaryotes – invalidating filings by the University of California, the University of Vienna, and Emmanuel Charpentier on use in eukaryotes.

 

March 6th – As the world watched the disaster unravelling in Ukraine, the UK Government quietly dropped plans to double their ‘moon shot’ dementia research fund, cutting the amount from £160 million to £75 million instead (Source). Probably due to the fraud and “error” on COVID-19 spending (possibly as much as £16 billion – Source). Well, at least no money was wasted on dodgy personal protective equipment (Source… I’m really no good at sarcasm).

 

March 16th – A cross-party report from the UK Government’s Digital, Culture, Media and Sport Committee criticised the “UNBOXED: Creativity in the UK” event (also known as the “Festival of Brexit”) as “vague and shape-shifting“, saying that it lacked clear direction and was an “irresponsible use of public money“. Taking place between March and November, the event will cost £120 million (Source).

 

March 30th – “I give you the light of Eärendil, our most beloved star” – Using gravitational lensing, NASA’s Hubble Space Telescope scientists detected light from the farthest individual star ever seen to date. They named it Eärendil. The newly detected star is so far away that its light has taken 12.9 billion years to reach Earth (Click here to read more about this).

March 31st – The Russian Ruble returned to pre-Ukraine invasion levels demonstrating the amazingly power and effectiveness of Western “sanctions”…

In the world of Parkinson’s research, a great deal of new research and news was reported:

In March 2022, there were 1098 research articles added to the Pubmed website with the tag word “Parkinson’s” attached (3412 for all of 2022 so far). In addition, there was a wave to news reports regarding various other bits of Parkinson’s research activity (clinical trials, etc).
