Of Course, Masks Protect the Wearer!

Does Wearing a Mask Protect Me? Some Evidence Says Yes – The New York Times – By Katherine J. Wu – July 27, 2020

People wearing face coverings will take in fewer coronavirus particles, evidence suggests, making disease less severe.

Researchers have long known that masks can prevent people from spreading airway germs to others — findings that have driven much of the conversation around these crucial accessories during the coronavirus pandemic.

But now, as cases continue to rise across the country, experts are pointing to an array of evidence suggesting that masks also protect the people wearing them, lessening the severity of symptoms, or in some instances, staving off infection entirely.  Continue reading

Physical Activity as Cause and Cure of Muscular Pain

Physical Activity as Cause and Cure of Muscular Pain: Evidence of Underlying Mechanisms – free full-text /PMC5473374/ – July 2017

This article interested me because I’ve long noticed that exercise both increases and decreases pain, usually initially increasing but over time (days or weeks) decreasing.

I’m always having to balance my activity and rest to keep a positive effect, doing both, but not too much of either one.

I had not paid attention to the difference between occupational (or physical) therapy (OT) and “leisure time physical activity” (LTPA). This article explains why I haven’t progressed much in my physical therapy routines: they involve static load, repetitive movements, and high peak forces, All of these are damaging to a body with a connective tissue disorder, like EDS.  Continue reading

How to Talk to Your Doctor About Pain

How to Talk to Your Doctor About Pain – Health Essentials from Cleveland Clinic – June 2020

This article contains an excellent list of many descriptive words to help us describe very specific aspects of our pain.

There are many causes and types of pain, and everyone experiences it differently. Effective communication with your doctor is a key piece of the pain management puzzle.

“While most people think pain is all the same, there are actually several different types of pain,” explains pain management specialist Robert Bolash, MD.  

It seems most scientists, researchers, and even doctors assume that chronic pain is some generic entity, and that’s a ridiculous assumption.  Continue reading

Biomarkers May (or may not) Indicate Chronic Pain

Biomarkers May Indicate Chronic Pain, Aid Personalized Treatment – Pain Medicine News – by Kaitlin Sullivan – Apr 2020

People who suffer from chronic pain may have abnormal levels of 11 biomarkers related to metabolites and nutrient deficiencies, according to a retrospective observational study published in Pain Physician (2020;23[1]:E41-E49).

Although the research is still in its early phase, these findings provide a snapshot of physiologic abnormalities found in a subset of patients with chronic pain.

“Subset” is the critical word here. If these “abnormalities” aren’t found in ALL patients with pain, how can they be used as “biomarkers” for pain?

10 Years of Missing Data for Clinical Trials

Clinical trial sponsors must publish 10 years of missing data, judge rulesBy Lev Facher – Feb 2020

This shows how bad of a problem we have with scientific research, now that it’s been used and manipulated by financial interests. If a study can’t find the results the “payor” wants to “prove”, it simply disappears like it never happened.

For years, government research agencies have misinterpreted a law that requires them to collect and post clinical trial data, a federal judge ruled this week, leaving behind a 10-year gap in data that now must be made publicly available.

The ruling affects trials conducted for as-yet-unapproved drugs and devices in that 10-year stretch, according to a lawyer for the plaintiffs — meaning hundreds or even upwards of 1,000 noncompliant trials would be forced to post data.  Continue reading

Review: opioid management for chronic noncancer pain

Long‐term opioid management for chronic noncancer pain – free full-text /PMC6494200/ Cochrane Review: Jan 2010

I’ll start with these two key findings in the author’s conclusions from this extremely long Cochrane Review:

1. Many patients discontinue long‐term opioid therapy (especially oral opioids) due to adverse events or insufficient pain relief; however, weak evidence suggests that patients who are able to continue opioids long‐term experience clinically significant pain relief.

2. Whether quality of life or functioning improves is inconclusive. Many minor adverse events (like nausea and headache) occurred, but serious adverse events, including iatrogenic opioid addiction, were rare. Continue reading

Quick fix of CBT doesn’t last

Why depth therapy is more enduring than a quick fix of CBT | Aeon Essays –  by Linda Michaels – Mar 2020

Ever since I learned about Cognitive Behavior Therapy years ago, I haven’t been able to believe it’s the solution to anything but immediate, superficial problems.

The grounding belief of Cognitive Behavior Therapy is that it’s our thinking that drives our feelings and that by changing what we think we can change what we feel. Oh, so clever, aren’t we?

But thinking and feeling are interdependent: how we feel affects how we think, which then affects how we feel, which then affects how we think, and so on and on. I find this disregard for the state of organic human feelings a fatal flaw; we are not such simplistic “computing machines”.  Continue reading

More information not always better for decisions

When more information may not lead to better decisions | National Institutes of Health (NIH)March 3, 2020

Every day we use information about cause and effect to help make decisions. With advances in machine learning, computers are now able to turn data into sophisticated models of causation.

These models have the potential to help inform the choices that people make in their daily lives. However, it’s unclear how well people can use such models to make real-world decisions.

To me, this is about the difference between data, like raw numbers, and real information, like how the numbers interact with each other (causation, influence, etc.)  Continue reading

Microglia and Pain

Microglia may be the missing clue to solve the opioid epidemic – Sara WhitestoneNeuroscience – Université de Bordeaux – May 2019

neuroscientists have discovered a new therapeutic target for managing pain: microglia.

Pain, as an acute sensation, serves as a warning to help your body prevent injury or avoid further harm.

the message from your stubbed toe is forced to go through a series of checkpoints—or gates—which will either open or shut to control the intensity of pain you perceive.

When pain becomes chronic, this signaling and the gate controls go haywire. Nerves become hyper-sensitive, firing off messages to the brain even in the absence of an injury.   Continue reading

Blood Protein Changes Linked To Aging Process

Protein Waves In Blood Linked To Aging Process: Shots – Health News : NPR – by Richard Harris – Dec 2019

Scientists know that if they transfuse blood from a young mouse to an old one, then they can stave off or even reverse some signs of aging. But they don’t know what in the blood is responsible for this remarkable effect.

Researchers now report that they’ve identified hundreds of proteins in human blood that wax and wane in surprising ways as we age.

Wyss-Coray and his colleagues report in Nature Medicine on Thursday that these proteins change in three distinct waves, the first of which happens “very surprisingly” during our 30s, peaking around age 34.   Continue reading
