The latest research looked at a part of the brain called the olfactory bulb, which processes information about smell. Connecting the olfactory bulb and the nasal cavity is the olfactory nerve. Some researchers worry the olfactory pathway may also be an entry point for microplastics getting into the brain, beyond the olfactory bulb. Mauad and her team took samples of olfactory bulb tissue from 15 cadavers of people who died between the ages of 33 and 100. The presence of microplastics in the olfactory bulb doesn’t automatically mean there are microplastics elsewhere in the brain, such as regions related to cognition.

CNN —Tiny plastic shards and fibers were found in the nose tissue of human cadavers, according to a small new study. The threads and microplastic pieces were discovered in the olfactory bulb, the part of the nose responsible for detecting odors that sits at the base of the brain. Microplastics are polymer fragments that can range from less than 0.2 inch (5 millimeters) down to 1/25,000th of an inch (1 micrometer). However, an April 2023 study found that microplastics made of polypropylene appeared to exacerbate the advance of breast cancer. The nose is one of many ways through which microplastics can enter the body, experts say.

Graves’ death may ultimately be part of a disturbing jump in the number of heat-related deaths, which have doubled across the country in recent years. Another child, a 10-year-old, died of a “heat-related medical event” in July while hiking in an Arizona park. ‘Attempted to save his life for about an hour’The Disneyland Halloween Half Marathon started at 5 a.m. last Sunday. “We’re sort of entering a new era of risk perhaps associated with these increasing temperatures,” Howard said. Before Sunday’s half marathon, Graves posted another TikTok video under his popular @calebtravels user name about the arrival of Disney race weekend.

Taking a high dose of ADHD drugs is linked to more than five times greater risk of developing psychosis or mania, according to a new study published Thursday in the American Journal of Psychiatry. The research is among the first to find a relationship between escalating doses of the drugs — amphetamines, in particular — and a greater likelihood of psychotic symptoms. The drugs include Adderall, Vyvanse and generic amphetamines, such as dextroamphetamine. The medium dosage — 20 mg to 40 mg of Adderall, 50 mg to 100 mg of Vyvanse or 15 mg to 30 mg of dextroamphetamine — was linked to a 3.5 times higher risk. There was no increased risk of psychosis with another ADHD drug, Ritalin, which isn’t an amphetamine.

But a bipartisan group of attorneys general on Tuesday demanded that Congress require Surgeon General warning labels on social media apps to help curtail addiction and a mental health crisis among young adults. Teens spend nearly five hours a day on social media apps, according to a Gallup poll. “Everyone needs to know the risk associated with these social media platforms,” New York Attorney General Letitia James said in a statement. Appending a warning to social media apps requires Congressional approval. Congress has so far ignored Murthy’s plea to introduce a bill requiring warning labels.

But a new study has found that a particular group of chemicals called metabolites, which are tested for as part of routine newborn screenings, could identify babies with an elevated risk. The researchers compared the results of newborn screening tests for 354 infants who died of SIDS with 1,416 infants who did not. “Maybe we’re looking at some food sensitivities,” she said, but added that much more research is needed into the link between SIDS risk and metabolism. Dr. Joanna Parga-Belinkie, a neonatologist at Children’s Hospital of Philadelphia who also wasn’t involved, similarly questioned whether newborn screenings can provide enough answers. “But every baby that’s born isn’t going to get a deep-dive genetic evaluation — they do get newborn screenings,” she added.

Parents, put down your phones (sometimes)
  + stars: | 2024-09-06 | by ( Dr. Katie Hurley | ) edition.cnn.com   time to read: +7 min
As a therapist who works with teenagers, I routinely hear from clients that their parents consistently criticize kids’ phone use but don’t curb their own use. Parents often tell me the same thing — their kids are glued to their phones and don’t listen when they try to engage them. And when parents feel rejected, they also turn their attention to their phones. I tell parents and kids alike that everyone needs to make changes in their technology habits to restore positive communication and trust. Keeping phones out of the bedroom is a common rule among parents of tweens and teens, yet this rule doesn’t often apply to the parents (guilty as charged).

CNN —Eating an anti-inflammatory diet of whole grains, fruits and vegetables instead of an inflammatory diet focused on red and processed meats and ultraprocessed foods, such as sugary cereals, sodas, fries and ice cream, lowered the risk of dementia by 31%, a new study found. “Following an anti-inflammatory diet was related to lower risk of dementia, even among people with cardiometabolic diseases who are already at elevated risk of dementia,” said Dove, a doctoral student at the Aging Research Center at Karolinska Institutet in Solna, Sweden, in an email. Brain scans of those who followed an anti-inflammatory diet also showed significantly lower levels of brain biomarkers of neurodegeneration and vascular injury, Dove said. carlosgaw/E+/Getty Images/FileWhat is an anti-inflammatory diet? Just a 10% increase in such foods was significantly associated with a 14% higher risk of death from all causes, according to a February 2019 study.

One paper published just this year sheds some light as to why tablet use could be related to anger outbursts. This is in the context of near-universal use of social media, with up to 95% of kids ages 13 to 17 reporting using social media. American teens report spending a shocking amount of time — nearly five hours each day—on YouTube, TikTok, Instagram and other social media apps. There are a number of problems with this level of social media use, one of which is what this time is replacing. Third, for those whose kids already have smartphones and use social media apps, speak with them about the impact of social media on them.

Most commonly, women use the abortion pills mifepristone and misoprostol. Researchers surveyed 7,000 women ages 15 to 49 and found that in the year before the Dobbs decision, 2.4% reported self-managing abortions. Slightly fewer women used the abortion pills misoprostol and mifepristone. For nearly a decade, she has worked with organizations like SASS — Self-Managed Abortion; Safe & Supported, a global nonprofit that provides information and access to medication abortions. So it can be shared in any state.”Nearly two-thirds of abortions in the U.S. are now medication abortions, according to the Guttmacher Institute.

What to know about menopause, according to a doctor

Around 90% of women experience menopausal symptoms, which can include hot flashes, sleep disturbances, mood alterations and weight gain. Some 94% of US women reported never being taught about menopause at school, according to a 2023 study. Most women go into menopause between ages 40 and 58, with the average age of experiencing menopause being 51, according to the North American Menopause Society. Last year, the US Food and Drug Administration approved a medication, fezolinetant, specifically for use in reducing hot flashes. However, studies have shown that many providers are not trained to provide the full range of options for menopause treatment.

Read previewSix months after he started taking a weight-loss drug, a 62-year-old man was hospitalized with heart palpitations, tremors, confusion, fever, and sweating. The man, from Colorado, had been prescribed the drug tirzepatide (the active ingredient in Mounjaro and Zepbound) to lose weight. Over time, the patient decreased his insulin dose as he lost weight, but didn't change his thyroid medication. This highlights the potential risks of losing weight too quickly, and the need for medical supervision while using the drugs, they said. AdvertisementOzempic and Wegovy, brand names for semaglutide showed weight loss of about 15% over a similar time period.

Most people undergo a knee replacement due to osteoarthritis in the joint, which can cause pain, swelling and less knee mobility. “We’ve always had this idea that muscle mass matters and helps protect joints,” said Miller, who was not involved with the study. The data that van Meurs and her colleagues studied came from people with an average body mass index of 26. “Before engaging in a lot of weight-bearing activity, do some training in the gym to strengthen your leg muscles,” van Meurs said. And if you’re going to take up a weight-bearing activity such as running, start slowly.

CNN —Mali has severed diplomatic ties with Ukraine after the country supplied intelligence to Malian rebels involved in an ambush against Wagner Group forces in July. Known for ad hoc cooperation, they appear to have collaborated to trap the Russian convoy. A Tuareg militant group spokesman said some Malian troops and Russian fighters had also been captured during the battle. According to some unofficial Russian Telegram channels, as many as 80 Russians were killed. Previous reporting contributed by CNN’s Tim Lister, Avery Schmitz and Darya Tarasova.

Consumers who try to buy popular weight loss drugs online without a prescription risk being scammed or receiving unsafe products, a new study shows. Shortages of the popular weight loss medication, which belongs to a class of drugs called GLP-1s, have led to “a black market of illegal knockoffs,” said Dr. Christopher McGowan, the founder, medical director and research director of True You Weight Loss, a weight loss clinic in Cary, North Carolina. Medicare doesn’t cover the drugs when prescribed for weight loss, and many state Medicaid plans heavily restrict coverage. Online scamsSome websites purporting to be online pharmacies take consumers’ money but never deliver the medications, according to the study. Consumers won’t get that sort of care if they buy drugs online without seeing a health care provider.

CNN —Regular aspirin use may keep the oncologist away, at least when it comes to colorectal cancer, according to a new study, and people with unhealthy lifestyles seemed to see the greatest benefit. Colorectal cancer is the second most common cause of cancer death worldwide, predicted to cause more than 52,500 deaths in the US alone in 2023. The use of two or more regular-strength aspirin or six or more low-dose aspirin per week was considered regular aspirin use for the purpose of this research. Those regular users were found to have an 18% lower risk of developing colorectal cancer than non-users. They argue that doctors should weigh different lifestyle risk factors when they determine whether someone should take regular aspirin to prevent colorectal cancer.

Self-managed abortions happen outside of the formal health-care system and without the formal supervision of a doctor or nurse. The new study suggests that self-managing an abortion with abortion pills has become more common, rising from about 18% of attempts pre-Dobbs to 24% post-Dobbs. Other research has found that abortions within the formal health care system have increased in the US post-Dobbs, driven by a spike in medication abortions, especially those provided through telehealth. “As barriers to facility-based abortion grow, (self-managed abortion) may increasingly become an individual’s only or preferred option to end a pregnancy,” the researchers wrote. “These findings suggest the need to expand access to alternative models of safe and effective abortion care and ensure those seeking health care post-(self-managed abortion) do not face legal risks.”

A Tuareg militant group spokesman said some Malian troops and Russian fighters had also been captured during the battle. According to some unofficial Russian Telegram channels, as many as 80 Russians were killed. The commander – call-sign Rusich – said on Telegram he was trying to convey a message to the Russian Defense Ministry. And in Syria five years ago, a disastrous attack by Russian mercenaries on an oil refinery led to dozens of casualties. One of them was an IED attack on a Russian vehicle in the same region of Mali as the latest devastating assault.

CNN —When she leaves Barbie Land for the real world, Barbie must keep up with her regular health maintenance, which includes seeing her gynecologist. Those examples and others inspired the researchers to look into the “Barbie” effect on interest in women’s reproductive health. But the authors noted that an increase in seeking gynecologic care may not be accurately captured in search trends. It’s possible that the searches were from people who don’t need gynecologic care, the authors note in the study. “I feel like (the scene) starts the conversation — anything that starts the conversation about reproductive health tends to cause folks to want to explore that and go in and take a look at what they should be doing about their own health,” Irobunda said.

CNN —More and more people are using marijuana before or during pregnancy to ease nausea, pain, stress and help with sleep. What about the potential danger to the mother if she uses cannabis before or during early pregnancy? People who used marijuana in early pregnancy also had a “19% greater risk of placental abruption,” Young-Wolff said. Using at least once a month or more was linked to a greater risk of placental abruption, the study found. “More studies are needed to understand whether and how cannabis use in pregnancy may impact risk for gestational diabetes,” Moore said.

In recent decades, mental health providers began screening for “adverse childhood experiences” — generally defined as abuse, neglect, violence, family dissolution and poverty — as risk factors for later disorders. In fact, the risk of moving frequently in childhood was significantly greater than the risk of living in a poor neighborhood, said Clive Sabel, a professor at the University of Plymouth and the paper’s lead author. “Even if you came from the most income-deprived communities, not moving — being a ‘stayer’ — was protective for your health,” said Dr. Sabel, a geographer who studies the effect of environment on disease. The study, a collaboration by Aarhus University, the University of Manchester and the University of Plymouth, included all Danes born between 1982 and 2003, more than a million people. Of those, 35,098, or around 2.3 percent, received diagnoses of depression from a psychiatric hospital.

Now, a new study has found those who experience more gratitude also have a lower risk of dying. The researchers used data from the Nurses’ Health Study, which included nearly 50,000 women between ages 69 and 96 who completed a six-item gratitude questionnaire in 2016. The researchers controlled for factors such as psychological well-being, health issues and other demographics including social and religious participation. There’s no clear consensus on how often one should practice gratitude, Simon-Thomas said. Having more gratitude has also been linked to being more optimistic in general, and people who express higher levels of gratitude tend to look more for the good in life, Watkins added.
