So maybe its the plastics?

 from SCIDAILY:

another study about plastics and obesity

Source: NYU Langone Health / NYU Grossman School of Medicine Summary: A sweeping review from NYU Langone Health reveals that everyday exposure to plastics—especially during childhood—poses lasting risks for heart disease, infertility, asthma, and even brain development issues. These chemicals, found in packaging, cosmetics, and common household items, can disrupt hormones, ignite chronic inflammation, and lower IQ.

 the only problem: For many things, there is no safe substitute for plastics. Sigh.

Harvard study on tylenol

Science Daily report on the TYleonl controversy:

Source: Harvard T.H. Chan School of Public Health 

Summary: Researchers reviewing 46 studies found evidence linking prenatal acetaminophen (Tylenol) exposure with higher risks of autism and ADHD. The FDA has since urged caution, echoing scientists’ advice that the drug be used only at the lowest effective dose and shortest duration. While important for managing fever and pain in pregnancy, prolonged use may pose risks to fetal development. Experts stress careful medical oversight and further investigation.

Pain relief in minoirites


Stanford study.

RESULTS. Approximately 28%
of the Hispanic and 31% of the African-American patients received analgesics of insufficient strength to manage their pain. Although the majority of patients received appropriate analgesics, 65% reported severe pain. Physicians underestimated pain severity for 64% of the Hispanic and 74% of the African-American patients. Physicians were more likely to underestimate the pain severity of female patients than male patients. Inadequate pain assessment, patient reluctance to report pain, and lack of staff time were perceived as barriers to pain management. CONCLUSIONS. Although the data suggest recent improvements in analgesic prescribing practices for African-American and Hispanic cancer patients, the majority of patients reported high levels of pain and limited pain relief from analgesic medications. Inadequate pain assessment remains a major barrier to optimal cancer pain treatment.

something to remember the next time the experts decide to make it harder for patients in pain to get pain medicines because they might be diverted.Yes diversion is a problem, as is family mamembers or friends who steal their medicine. But most of the overdose deaths are from street drugs, so why make patient suffer?

Ahd where the hell are the pastors/bishops/pope on this? It was the methodist/Baptists who worked against the cheap gin and alcohol abuse two centuries ago, but aside from AA in church basements, too often the preventive instructions in sermons is not part of their job.

The Dilbert scandal: MAID before adequate treatment

Scott Adams made it know that he was having severe (undertreated) pain from his prostate cancer and decided to kill himself legally, got his medicine, and even had the date set to do it.

But then a doctor suggested to him to use hormone blockers, which he had refused earlier because he was under the impression he would be a different person if he took them.

But according to a discussion here he tells of how one physician persuaded him to take hormone blockers, and since then he has gone into remission and is improving.

WTF?

now, these hormone blockers have a bad reputation because they are being misused to transition transexual children and stop puberty.


Wikipedia on GNRH Antagonists.

but they are used for other problems: hormone sensitive cancers, benign tumors, and (in my case) endometriosis.

I took a course of hormone blockers for benign tumors and endometriosis as an alternative to a hysterectomy so I could get pregnant (no I didn't get pregnant, but the point is that I was young and unmarried, and was grateful for them doing this since I did marry a few years later). They work by putting you into artificial menopause, so the benign tumors and the endometriosis, both of which are hormone dependent, shring. 

The hormone blockers did work: after several months of treatment and surgery to remove extensive scar tissue from the endometriosis, I remained pain free for ten years before the condition reoccured. 

But I cried every day on that treatment i.e. went into depression so I warned my male patients taking hormone blockers  for prostate cancer that if they got depressed, well it was the medicine, not reality.

So anyway, one is happy for Mr Adams that he was persuaded to take a fairly benign (next to chemotherapy) medicine for his cancer and presumably got a doctor to manage his pain relief and other cancer symptoms.

But you know: this shows that getting legal persmission to get drus to kill oneself is flawed.

and if a rich, intelligent guy like Mr Adams got poor treatment for his cancer, what about people like my patients, who tended to be poor, not sophisticated or educated, minorities, and lived far from expert care? 

what makes me especially angry? This is not an experimental drug.

GNRH Antagonists are a variation of an old and well known and widely used treatment for bone metastatses from Porstate cancer (and breast cancer too): estrogens or surgical castration.

 Hormone dependent cancers with metastates have long been treated by blocking the hormone. 

Before the GNRH Antagonists, they castrated men with prostate cancer, or gave them estrogen to turn off the male hormone that fed the growth of the cancer and relieve bone pain from metastases. (and for women, Ovarian removal was used for women with metastatic breast cancer.)

Back when I started medical school both castration and estrogen were used for prostate cancer, until a study showed that giving estrogen didn't prolong life in large studies because the patients had more heart disease. (never mind that part about pain relief).

So presumably blocking the hormone replaced estrogen.

So I asked Grok abbout using estrogen in prostate cancer:

Estrogen was first used for prostate cancer treatment in the early 1940s. Charles B. Huggins, a urologist, pioneered its use after discovering that hormonal manipulation could slow the growth of prostate tumors.
His research, published in 1941, showed that diethylstilbestrol (DES), a synthetic estrogen, reduced tumor activity in patients with metastatic prostate cancer, marking a significant milestone in hormone therapy. This work earned Huggins the Nobel Prize in 1966.

so Grok when did these hormone blockers replace estrogen for prostate cancer?

Estrogens, such as diethylstilbestrol (DES), were a primary hormone therapy for advanced prostate cancer from the 1940s until the late 1970s and early 1980s, when they were largely supplanted due to significant cardiovascular side effects like blood clots and an increased risk of heart disease.
This shift was driven by the introduction of gonadotropin-releasing hormone (GnRH) agonists (e.g., leuprolide and goserelin), which achieved medical castration more safely and effectively without the estrogen-related risks; the first patient was treated with a GnRH agonist in 1979, leading to rapid worldwide adoption by the mid-1980s.
GnRH antagonists (e.g., degarelix and relugolix), which suppress testosterone without the initial "flare" seen with agonists, did not directly replace estrogens. Instead, they emerged later as an alternative to GnRH agonists for specific clinical needs, such as avoiding flare in high-risk patients (e.g., those with spinal metastases).
The first GnRH antagonist, abarelix, was approved by the FDA in 2003 but withdrawn in 2005 due to allergic reactions.
Degarelix gained FDA approval in 2008, establishing GnRH antagonists as a viable option in clinical practice. Relugolix, an oral formulation, followed in 2020.
Today, both agonists and antagonists are standard androgen deprivation therapies, with antagonists preferred in certain cardiovascular-risk scenarios.

so one is happy that Mr Adams now is on the correct treatment for his painful cancer.

But if an intelligent and sophisticated man can't get decent treatment, what about ordinary folk, especially minorities?

the next big drug crisis?

Science Daily:

Nitazenes, a powerful and largely hidden class of synthetic opioids, are quickly becoming a deadly factor in the overdose crisis. Over 20 times stronger than fentanyl, these drugs often go undetected on routine drug tests, making overdoses harder to diagnose and reverse. Cases from Tennessee reveal a disturbing pattern of fatalities, with nitazenes frequently mixed into counterfeit pills alongside fentanyl and methamphetamine.


actually they have been around for awhile but are just starting to be a problem in the USA:
 

this video is from Australia
 

and yes, they come from China:

More here:

The illicit opioid supply is increasingly adulterated with novel synthetic opioids such as nitazenes. Nitazenes are very potent opioids and are increasingly associated with opioid overdoses and deaths. Despite their potency, nitazenes are reversed by naloxone. Given the high risk of overdose associated with these agents, improvements in the delivery of addiction care and naloxone distribution are needed to prevent morbidity and mortality from nitazenes and other novel opioids. The Evolution of the Opioid Crisis More than 107,000 drug overdose deaths occurred in 2022 with an age-adjusted rate of 32.6 deaths per 100,000 of the standard population.1 Since 2002, the age-adjusted rate of drug overdose deaths increased for both men and women, although from 2021 to 2022 the rate decreased by one percent for women. In 2021 and 2022, drug overdose death rates were highest for adults aged 35–44 years old; people over the age of 65 had the largest percent increase from 12.0 to 13.2%. Regarding overdoses involving synthetic opioids, including fentanyl and fentanyl analogs, rates increased from 2013 to 2022 (1.0 to 22.7%), while rates from heroin overdoses decreased from 2.8 to 1.8% from 2021 to 2022.

Ebola again

,,,,

according to ABC Australia this is the 15th outbreak, three years after the last one.

Key counter measures [included] testing, contact tracing, infection prevention and control, treatment and community engagement. "Vaccination — a crucial protective measure — was launched just four days after the outbreak was declared." The WHO said Congo had a stockpile of treatments as well as 2,000 doses of the Ervebo vaccine that will be transported to Kasai to vaccinate contacts and frontline health workers.

Isolation of cases, protective equipment, and ring vaccinaion is how previous outbreaks have been stopped.
