Lymphatics – Refresher

Lymphatics – a plumbing system that follows the circulatory system throughout the body including the brain where it is called the glymphatics. The function of these passively moving tubes is to transport fats around the body, clear cellular debris returning it to the liver and spleen, move fluid in and out of tissue to maintain fluid balance, transport and help immune cells function. By transporting fats , lymph is involved in vitamin movement to tissues and cells for Vitamins A, D, E, K. These are critical functions of metabolism, immunity and detoxification that when disrupted lead to chronic diseases of aging including edema, hypertension, autoimmunity and cardiovascular disease.

“Traditionally considered a passive route for transport of fluid, immune cells, and lipoproteins, lymphatics are now known to be active players in major physiological and pathophysiological processes. Until recently, lymphatic vessel dysfunction was mainly associated with primary and secondary lymphedema. Unexpectedly, however, lymphatic vascular defects have been uncovered in conditions such as obesity, cardiovas- cular disease, inflammation, hypertension, atherosclerosis, Crohn’s disease, glaucoma and various neurological disorders such as Alzheimer’s disease.” (Oliver et. al. 2021)…and a discussion on chemicals in school food.

Section I

Are Smart Phones a benefit or a curse for the teenager in school? This is becoming a huge topic this past year or so. Logic would seem to dictate that this is a curse more than a benefit, but what does the data and expert opinion show?

The Scientific American article “Do Phone Bans Help Students Perform Better in School?” examines the growing trend of banning smartphones in schools to enhance student performance and well-being. Numerous U.S. cities, including New York and Los Angeles, have recently implemented or are considering bans on phones in classrooms. Schools use tools like the Yondr pouch, which locks phones away during school hours, to enforce these bans. These measures are popular with educators and parents, with 60% of likely voters in New York State supporting such restrictions. Charlotte Schools has this policy: “In accordance with Charlotte-Mecklenburg Schools Student Code of Conduct, personal technology devices, including cell phones must remain off and put away during school hours. Violations will result in confiscation of the personal technology device. The district is not responsible (monetary value or replacement) for theft, loss or damage to personal technology or other electronic devices brought onto CMS property.” (CMS) My informal poll has a higher number of parents interested in phone ban restrictions in North Carolina….plus a section on teen anxiety.

Literature Review

1) Does oral health affect your life if you are sick and in intensive care? According to a new study in JAMA, the answer is yes. From the study: 10,742 patients – “toothbrushing was associated with significantly lower risk for Hospital Acquired Pneumonia and ICU mortality. Reduction in pneumonia incidence was significant for patients receiving invasive mechanical ventilation but not for patients who were not receiving invasive mechanical ventilation. Toothbrushing for patients in the ICU was associated with fewer days of mechanical ventilation and a shorter ICU length of stay. Brushing twice a day vs more frequent intervals was associated with similar effect estimates….Non-ICU hospital length of stay and use of antibiotics were not associated with toothbrushing.” (Ehrenzeller et. al. 2024)

Why does this matter? In effect, what this study shows is that patients with oral hygiene needs that are not met will have increased bacterial burdens leading to infectious disease risk via systemic inflammation and possibly bacterial translocation. At the end of the day, oral hygiene is very important to lower the total burden of inflammation in everyone, but especially in the most ill patient. It is super important for everyone to brush 2-3 x daily and floss daily at night…..

Plus a discussion on Back to School.

Sleep Part III

Finally, the other elephant in the room related to sleep is STRESS. Stress alters the function of the hormone cortisol and can significantly alter night sleep function. There are three major chemicals that affect sleep: cortisol, adenosine and melatonin.

In normal conditions, adenosine rises during the day making you sleepy, cortisol hits its low point at night and melatonin rises as the sun goes down. This combination puts pressure on you to feel sleepy and want to go to bed. Unfortunately, modern life has made many of us feel stressed and sympathetically fired up which affects cortisol function. Instead of being at its nadir at night, the stress response causes cortisol to rise at inappropriate times disrupting sleep onset and maintenance. Couple this stress with facebook addiction and screen induced melatonin suppression and you have a recipe for insomnia and disrupted sleep. (Hanson et. al. 2010)….Plus, a section on cellphones and driver knowledge.

Sleep Part II

Let us pause here! So far we now know that humans at all ages will suffer from memory dysfunction and brain sewage cleanup problems leading to inflammation and damage long term. What ages are most at risk? They are likely mirrored by other physiologic events that are at risk based on age. Teenagers, infants and toddlers are rapidly growing creatures requiring more macro/micronutrients, water, and toxin avoidance for success. It is likely that sleep follows these same principles.

Going to a simple google scholar search for “sleep deprivation age risk” brings up countless articles on the effects of sleep deprivation in mothers and children on risk of obesity, diabetes, premature birth and much more.

….Plus more on gender and emotion as well as a recipe of the week.

Reading

If you want to spend any amount of time with your child beyond hugs, feeding and basic life duties, I would recommend reading above all else. I find it hard to believe that this is the first article that I have written on reading. I pondered that for a minute and concluded that this, in effect, was me taking this information for granted. That ends today.

When I reflect on my journey on the road to reading literacy, I note that I was not an avid reader. Nay, I hated reading for most of my childhood. My first self chosen pleasure book was The Firm when I was 23 years old. Why would this be? To sit for me was and is akin to mild torture. While other kids loved to dive into a book, that was not for me. Run, play, drum, hike, yes sir. All in….plus a Literature Review and section on Memorial Day.

Enjoy,
