Not in the Fauci paper but what is mentioned is the increase in mouth bacteria. He says masks won't work here - FauxChi on wearing masks no good

And more from Dr. Colleen Huber -

This is some very interesting information on mask wearing from Dr. Colleen Huber. This urinalysis test is from a patient who is a long time mask wearer who came in complaining of some health issues. Note the PH level in this person's Kidneys! Now read why this can be deadly. This patient wears a mask many hours per day. Here's what happened to the urine. Obstructed air flow keeps more carbon dioxide for extended time in masked airspace --> more carbon dioxide in lungs (hypercapnia), which lowers your pH and increases acid condition (respiratory acidosis) which overwhelms compensatory mechanisms of the body. The kidneys now have the hard job of dumping acid. How do the kidneys get rid of bad stuff? They need to excrete that acid in the urine. Urinalysis shows very low pH (bottom of the chart: pH = 5.0) That's about as acid as coffee! Which is fine for coffee, but not so great for urine, which reflects what got taken from blood (remembering that kidneys' main job is to clean the blood, by excreting less than ideal substances into urine for disposal). The moral of that story is that masks, by way of the lungs, not only harm the brain (hypoxia), and the heart (tachycardia) and the immune system (acid favors viral replication), but also the kidneys. I am concerned that the hematuria and proteinuria may also result from this strain on the kidneys. As nephrologist Dr. Humphries @DrsuzanneH says, "If you wear a mask, I hope you have strong kidneys." Organs other than the kidneys have shown strain under mask use as well, which seems to be widely acknowledged, but not very alarming to mask-wearers. For example: It is widely acknowledged that people wearing masks often suffer headaches, foggy thinking or lightheadedness. But this only seems to affect the brain, which is notoriously oxygen-hungry. So perhaps brain needs are not seen as the most urgent consideration. Also, many people have noticed higher heart rate while wearing a mask. This is because low available oxygen forces the heart to beat faster, to rush red blood cells around to the various body systems to try to meet ongoing needs, particularly the oxygen-greedy brain. But perhaps that added strain on the heart is taken in stride, stoically, due to the compulsion to wear a mask. And mask use lowers oxygen intake while increasing carbon dioxide accumulation in the lungs, which leads to the acidic condition of hypercapnia. And it is long-known and well-established that acidic conditions favor viral replication. But perhaps the public realizes that COVID19 is not nearly as lethal as the US media portrays it to be. So therefore, mask impairment of the immune system’s ability to fight viruses seems to be accepted by those who advocate mask use as a necessary disadvantage.

i read here recently, the OR has oxygen pumped in to compensate for the masks.

Ofc, its the internet, so it must be true.

From what I read elsewhere, the inference drawn in the paper is that wearing masks constantly creates the bacterial environment that causes the bacterial pneumonia

The word "mask" doesn't appear in the document.
