Is fitness the new religion? American religious affiliation has been on the decline while gym memberships have sky-rocketed. Daily Show writer and comedian, Randall Otis, explores the connection between physical health and spiritual belonging.

Deep Sleep Brainwashes Us All, Study Claims



By Adam Townsend on 11/12/2019 3:51 PM

What happens to your brain when you fall asleep? New real-time brain imaging has shed more light on what happens to our brains in the dark; slow waves of fluid wash in and out of our skull and carry away harmful excess proteins during deep sleep.

Laura Lewis, a researcher at Boston University, was part of a team that demonstrated the first direct evidence of this tidal action of cerebrospinal fluid, the clear, pressurized solution that bathes our spinal cords and brains and keeps them running smoothly.

“We’ve known for a while that there are these electrical waves of activity in the neurons,” Lewis told The Brink, Boston University’s science magazine. “But before now, we didn’t realize that there are actually waves in the (cerebrospinal fluid), too.”

This research has broad implications for all sorts of neurodegenerative disorders, including autism, Alzheimer’s, and dementia. These conditions are closely linked with sleep disturbance, and some cause buildup of protein deposits in the brain – beta-amyloid plaques, for instance — made of the harmful waste products your cerebrospinal fluid is supposed to wash away.

Slow, even waves of electromagnetic activity are a well-documented characteristic of deep sleep, Lewis said. These waves pave the way for memory consolidation and optimal brain function during the day, according to the current thinking.

But the BU study, published this month in the journal Science, marks the first time those electrical oscillations have shown a connection to fluid dynamics in the brain.

The study relied on a functional MRI machine – a device that images the inside of the brain in real time rather than producing still images as a regular MRI does. The Boston team showed slow electric waves were associated with increased oxygenated blood flowing into the brain, followed by a wave of cerebrospinal fluid.

The study participants were all aged 23 to 33, so the next round of tests will recruit older participants, Lewis said. The slow waves of deep sleep reduce in frequency as you age, which Lewis said may be connected to memory-killing plaque and metabolite buildup. Ideally, researchers will be able to understand the interplay between the electrical signals and changes in blood and fluid volume in older adults. This data will hopefully contribute to treatments and new prevention measures for age-related and other forms of dementia, Lewis said.

How Much Deep Sleep Do You Need?

Deep sleep, as defined above, only accounts for about 20% of total sleep. The largest amount of deep sleep takes place in the first half of the night, according to Melissa Conrad Stöppler, MD, a pathologist and MedicineNet author/editor.

Individuals vary greatly in their need for sleep in general; there are no established criteria to determine exactly how much sleep a person needs. Eight hours or more may be necessary for some people, while others may consider this to be too much sleep, Dr. Stöppler said.

The National Institutes of Health (NIH) suggests that most average adults need about 7 to 9 hours of sleep each night. Newborn babies, by contrast, sleep from 16 to 18 hours a day. Preschool-aged children typically sleep between 10 and 12 hours a day. Older, school-aged children and teens need at least 9 hours of sleep a night. Women in the first trimester of pregnancy have been observed to need a few more hours’ sleep than is usual for their age, Dr. Stöppler said.

Physiologically, sleep is a complex process of restoration and renewal for the body. Scientists still do not have a definitive explanation for why humans have a need for sleep, Dr. Stöppler said.

We do know that sleep is not a passive process or “switching off” of body functions; sleep is believed to be important in many body processes, Dr. Stöppler said. It allows us to process experiences and consolidate memories. It is also clear that sleep is essential, not only for humans but for almost all animals.

The importance of sleep is underscored by the symptoms experienced by those suffering from sleep problems, Dr. Stöppler said. People suffering from sleep disorders do not get adequate or restorative sleep, and sleep deprivation is associated with a number of both physical and emotional disturbances.

Double Lung Transplant in Vaping Case a Success



Nov. 12, 2019 — The first double lung transplant done as a result of a vaping injury is a success, with the 17-year-old high school athlete on the road to recovery, doctors at Henry Ford Hospital in Detroit said Tuesday.

Doctors did the 6-hour transplant Oct. 15 after the patient’s situation became more and more critical. Doctors describing the surgery at a news conference Tuesday said the lung injury came entirely from vaping.

“What I saw in his lungs is something I never saw before, and I have been doing lung transplants for 20 years,” said Hassan Nemeh, MD, surgical director of thoracic organ transplant at Henry Ford Hospital. He was one of three surgeons on the transplant team. “This is an evil I have not faced before.”

The patient, previously an active high schooler, is still hospitalized. He is close to being transferred to rehab and is expected to be able to return to school. Nemeh said he hopes the teen will talk about the dangers of vaping. “I would expect him to be an advocate to stop this madness.”

The donor was healthy, Nemeh said, but gave no further details.

The severity of the teen’s condition quickly put him high on the national waiting list, Nemeh said.

The teen was admitted to a hospital on Sept. 5 and needed intubation by Sept. 12. On Sept. 17, he was hooked up to a heart-lung machine treatment called ECMO (extracorporeal membrane oxygenation) to keep him alive. He continued to decline and was transferred to Henry Ford on Oct. 3, then put on the waiting list on Oct. 8.

The family of the teen asked for privacy but asked the medical team to share a statement: “He has gone from the typical life of a perfectly healthy 16-year-old athlete — attending high school, hanging out with friends, sailing and playing video games — to waking up intubated and with two new lungs, facing a long and painful recovery process as he struggles to regain his strength and mobility, which has been severely impacted.”

He turned 17 while in the hospital, doctors said.

Lung Transplants in the U.S.

In 2018, 2,530 lung transplant procedures (including both single and double) were done in the U.S., according to the Organ Procurement and Transplantation Network. No breakdown is available on what percent were double.

There are now 1,422 patients on the waiting list for a lung.

During the procedure, a surgeon removes the diseased lung or lungs and attaches the donor lung or lungs to the airway and the blood vessels that lead to and away from the heart. In some cases, the lungs are transplanted along with a donor heart.

Among the common reasons for a transplant are chronic obstructive pulmonary disease (COPD), lung scarring from pulmonary fibrosis, high blood pressure in the lungs known as pulmonary hypertension, or cystic fibrosis, a hereditary disorder that affects the lungs.

Experts Weigh In

A transplant is called for only when there’s severe lung damage, says Wayne Tsuang, MD, an assistant professor of medicine at Cleveland Clinic and a practicing lung transplant pulmonologist. He was not involved in the Detroit patient’s medical care.

“It would have to be end-stage lung disease, in that all the potential medical treatments were exhausted and the team taking good care of him had no other options to salvage his lungs,” he says.

Among those options are oxygen, prescribing steroids to lessen the inflammation in the lungs, and giving antibiotics if pneumonia sets in.

“There are different criteria for different diseases, but overall, very severe lung disease [has to be present],” agrees Mangala Narasimhan, DO, regional director of critical care medicine and a pulmonologist at Northwell Health, New Hyde Park, NY. She was not involved in the Detroit patient’s medical care.

In general, Tsuang says, 1-year survival is about 85%, while 50% of transplant recipients are alive at 5 years. The range varies greatly and depends on things like other health conditions that may be present.

“The median survival for all adult recipients is 6.5 years,” says Narasimhan, citing 2018 national statistics.

The long recovery includes taking anti-rejection medications for the rest of the patient’s life. Often, that involves a dozen new medications, Tsuang says.
