  • The body’s circadian rhythm helps ensure the body goes through all the natural processes that need to occur in a 24-hour cycle.
  • Past research shows circadian rhythm can affect certain health conditions and how well medications work.
  • Researchers from the Swiss Federal Institute of Technology have found circadian rhythm may also impact a person’s cancer diagnosis and treatment success.

The body’s circadian rhythm — the natural 24-hour cycle that happens throughout the day — has an impact on sleep.

However, previous research has also found the circadian rhythm to have an effect on a number of health concerns, including mental health disorders, epilepsy, cardiovascular disease, and diabetes.

A study in April 2021 found that a person’s circadian rhythm may influence how effective certain medications are depending on what time of day they are administered.

Now, researchers from the Swiss Federal Institute of Technology (ETH) Zurich believe that the circadian rhythm may also impact cancer diagnosis and treatment success.

The study was recently published in the journal Trends in Cell Biology.

The circadian rhythm is basically a master clock for the body.

Every day, the body goes through a cycle of processes that last for about 24 hours. This includes physical, behavioral, and mental changes, including hormonal activity and digestion. The circadian rhythm ensures the body goes through these processes.

Circadian rhythm also regulates the body’s sleep/wake cycle. During the day, the circadian rhythm helps us feel awake and alert. At night, it helps ensure the body rests through sleep.

Certain things can disrupt the body’s natural circadian rhythm, including:

If a person’s circadian rhythm becomes disrupted, they can have a circadian rhythm sleep disorder.

And previous studies in mice have linked disrupted circadian rhythm to cancer development.

In this study, the research team analyzed current data known about circadian rhythm and cancer development, diagnosis, and treatment.

The scientists found that metastasis — the spread of cancer cells from the original site to another area of the body — is connected to the circadian rhythm.

For example, the authors state, breast cancer is more likely to metastasize at night while a person is asleep, whereas prostate cancer is more likely to metastasize at other times during the day.

The authors believe that a person’s circadian rhythm could influence the effectiveness of chemotherapy and immunotherapy treatments. A process called chronotherapy can be used to coordinate treatment delivery with the body’s circadian rhythm.

Study researchers also found that the time of day a person receives cancer treatment may impact how successful it is.

The scientists cited a study in 2021 showing that people with melanoma who received immunotherapeutic drugs before 4:30 p.m. were almost twice as likely to survive as people who received the treatment later in the day.

The research team reported that the circadian rhythm might help doctors with cancer diagnosis.

As cancer cells make proteins at different times of the day, researchers believe that knowing when these proteins are at their highest concentration can help decrease misdiagnosis and help when performing biopsies.

After reviewing this study, Dr. Santosh Kesari, a neuro-oncologist and director of neuro-oncology at Providence Saint John’s Health Center, chair of the Department of Translational Neurosciences and Neurotherapeutics at Saint John’s Cancer Institute in Santa Monica, California, and regional medical director for the Research Clinical Institute of Providence Southern California, said this is a new concept that is not yet well understood.

Dr. Kesari, who was not involved in the research, told Medical News Today that, nevertheless:

“[B]ased on a variety of mostly preclinical data, and maybe some clinical data too, it seems like the circadian rhythm can have some profound effects, not just obviously on sleep and other functions, but a lot of biology in terms of cancers developing and also treating cancers and how the circadian rhythm can affect the effectiveness of the various treatments — immunotherapy and chemotherapy — that we give patients.”

Dr. Manmeet S. Ahluwalia, deputy director, chief scientific officer, chief of medical oncology, and Fernandez Family Foundation Endowed Chair in Cancer Research with Miami Cancer Institute, part of Baptist Health South Florida, who was also not involved in this study, weighed in on the argument.

He said that, if this concept is validated in a prospective setting, in the future it may help doctors recommend treatments at a particular time of the day to enhance efficacy or minimize side effects.

“For example, in patients with ovarian cancer who receive Adriamycin in the morning and cisplatin in the evening, they experience fewer side effects than patients who received Adriamycin in the evening and cisplatin in the morning,” he noted.

Both doctors agreed that additional research on this topic is needed before major changes are adopted.

“As the findings could have a far-reaching impact on how we treat our cancer patients, it would be great if the research related to circadian rhythm could be validated in a prospective clinical setting with translational research built-in to support the clinical findings,” Dr. Ahluwalia said.

Dr. Kesari cautioned that because cancer takes many years to develop in the body, it may be hard to study the impact of circadian rhythm on cancer development in humans.

Still, “I think there [are] some mouse models that can be studied to see disrupting [the] circadian rhythm and what it predisposes to,” he added.

With regards to circadian rhythm’s impact on cancer treatment, Dr. Kesari said that is really critical.

“The question is how big of an effect and is it really worth it to change whether we treat in the morning or afternoon or evening based on the circadian rhythm,” he stressed.

“I think there is a lot more to learn. And in particular, applying it to humans is going to be difficult, obviously, because the clinics are open 8 a.m. to 5 p.m. or 6 p.m. If it’s an IV chemo, then timing it in that context is not easy. Obviously, oral chemos or oral treatments can be done much easier at a specific time.”

NYT ripped for only reporting Fetterman’s ‘serious mental health’ issues ‘now that the truth doesn’t matter’

NYT ripped for only reporting Fetterman’s ‘serious mental health’ issues ‘now that the truth doesn’t matter’

Community figures are brazenly talking about how Sen. John Fetterman, D-Pa., faces long lasting psychological issues, a thirty day period just after he was sworn in and a Democratic Senate the greater part secured.

FETTERMAN HEARS VOICES LIKE THE Instructors IN ‘PEANUTS’ Following STROKE, STRUGGLES TO Modify TO SENATE Existence: REPORT

“But his adjustment to serving in the Senate has been made vastly extra complicated by the strains of his restoration, which remaining him with a physical impairment and severe psychological health challenges that have rendered the transition extraordinarily difficult — even with the accommodations that have been made to assistance him adapt,” according to The Periods.

“He has had to come to terms with the point that he may perhaps have established himself back completely by not having the recommended total of relaxation for the duration of the campaign,” the posting explained. “And he continues to thrust himself in approaches that people today shut to him fear are harmful.”

In light-weight of this information, numerous commentators across Twitter condemned media outlets for obfuscating Fetterman’s well being problems in order to make certain he gained the election in 2022.

Media temperament Steve Krakauer tweeted, “NYT is completely ready to inform the real truth about John Fetterman – who continues to be in the clinic for a 3rd working day – now that the truth of the matter isn’t going to subject.” He then quoted from the article: “a physical impairment and severe psychological wellbeing problems that have rendered the transition terribly tough.”

Unbiased journalist Glenn Greenwald slammed quite a few media shops for getting hidden or minimized Fetterman’s wellbeing fears although he was operating for office environment. 

“Modern NYT short article on Fetterman will make clear his incapacities and overall health troubles are much graver than were being identified,” he wrote. “Almost nothing but the finest of needs to Fetterman and his restoration, but it is urgent to remember how aggressively and intentionally the media lied about this to elect him.” 

He singled out tech journalist Kara Swisher, suggesting she cynically defended Fetterman’s concerns as a political ploy.

“Appropriate prior to the election, an NBC reporter, @DashaBurns, did her most primary occupation by actually reporting Fetterman seemed incapable of speaking and knowing her,” Greenwald tweeted, “She was mauled by liars like @karaswisher who, eager to elect Dems, attacked the reporter.”

Greenwald recommended this was component of a significantly larger sized phenomenon in American politics.

“This is why I genuinely regard [Podcaster] Sam Harris’ admission as one of the most important statements in a long time,” he wrote. “When he said nearly anything and almost everything is justified to help Dems earn – lying, censorship, disinformation – he was conveying what most in media and remaining-liberal politics consider.”

X Procedures LLC senior electronic strategist Greg Price tweeted, “The Democrat Social gathering practically gave John Fetterman lasting brain damage just to have a vote in the senate to get rid of unborn toddlers.”

Fox New senior political analyst Brit Hume tweeted that this info from the New York Times is hardly a shock to a lot of.

“Some of us warned for the duration of his marketing campaign that his stroke experienced still left him unable to complete everyday obligations of a U.S. Senator,” he wrote. “Now the New York Times reports that, his latest hospitalization aside, he continue to just isn’t.”

Defense of Flexibility spokeswoman Angela Morabito tweeted an excerpt of the write-up and wrote, “What they’re doing to John Fetterman is abuse, plain and easy.”

The Spectator contributing editor Stephen L. Miller explained, “In accordance to an outraged 19th News reporter, NY Periods stealth edited out the phrase ‘special needs’ about the point John Fetterman essential particular captioning displays put throughout the Senate developing.”

He copied and pasted an impression of a tweet from Sara Luterman right after she experienced condemned The Times for applying the phrase “unique demands” simply because Fetterman’s “demands are not ‘special.” She wrote, “Update: ‘Special needs’ has been eradicated. Thank you for earning the correction, @nytimes. I’m still form of stunned it designed it by means of in the 1st put.”

Pluribus editor Jeryl Bier reported the incident casts question on whether significantly of the media would report honestly on President Joe Biden’s health and fitness. 

“If Pres. Biden actually does have wellbeing difficulties, what about the way John Fetterman’s overall health was noted prior to the election would give the general public any self-confidence we’d study anything about it? Or would we just be informed afterwards how the White Property ‘adapted’?” he asked.
