Research Shows Common Disinfectant Wipes Expose People to Hazardous Chemicals | US news



Since the start of the pandemic, the global use of disinfectants has skyrocketed. Clorox sharply increase in production of its tissue packs to 1.5 million per day by mid-2021, and the industry trade group said 83% of consumers surveyed around the same time reported using disinfectant wipes in the last week.

But as schools reopened, the toxic chemicals research team grew concerned as they heard reports of children regularly using disinfectant wipes on their classroom desks or teachers using disinfectant sprays.

The researchers knew that disinfectants did little to protect consumers from Covid and instead dangerously exposed children to what they say is a chemical group – quaternary ammonium compounds, also known as QAS or “quats.”

Quats are common ingredients in popular disinfectant wipes and sprays, especially those that claim to “kill 99.9% of germs.” But in the new peer-reviewed articleThe researchers have compiled findings from a rapidly growing number of quat studies that point to several key questions: chemicals are associated with serious health problems, they promote antimicrobial resistance, they pollute the environment, and are not particularly effective.

The chemicals “may be ineffective, but they can also be harmful,” said Courtney Carignan, co-author of the paper and a toxicologist at Michigan State University.

“We did a survey to answer the question, ‘What do we really know?’ and what was most surprising was that most of the QACs lacked health hazard data, and the few that were studied have red flags,” Carignan added.

The paper, produced by a group of toxicology researchers from academia, government agencies and non-governmental organizations, highlights the risks associated with quaternisms and urges regulators to eliminate chemicals for non-essential uses.

HACs are a class of hundreds of chemicals that are also used in paints, pesticides, hand sanitizers, personal care products, and more. Among other health problems, recent research has linked them to infertility, birth defects, metabolic disorders, asthma, skin conditions, and other conditions.

The main exposure is through disinfectants, and most Americans think they have some level of chemicals in their blood. recently research who tested the serum of more than 200 Indiana residents before and after the start of the pandemic found that quat levels roughly doubled, and while about 83% had detectable levels before the pandemic, 97% did after.

People can enter the body with quats in several ways. Chemicals can be absorbed through the skin or orally after touching a disinfectant wipe or when they are left on surfaces after using disinfectants. Inhalation is also a risk, especially when using aerosol disinfectants, and chemicals are also known to attach to dust and become airborne.

Among the groups most at risk are young children because wipes are so commonly used in kindergartens or schools, supervised elderly people, healthcare workers, janitors and others who frequently use disinfectants.

The chemicals are persistent and are considered bioaccumulative, meaning they accumulate in the human body and the environment. quats were found be toxic to fish and “a substantial body of evidence” offers they likely contribute to the creation of superbugs or antibiotic-resistant pathogens, the paper says.

This also calls into question the effectiveness of the quaterns. Research shows that quat disinfection often has only a slight advantage over plain soap and water when it comes to killing germs, and it is believed that neither is needed to stop the transmission of Covid, which occurs through the air.

“The disinfectant will get rid of more germs, but the question is: How much more?” Carignan said.

However, companies continue to use quotas and consumers buy disinfectants in bulk, which Carignan says could be “a market demand situation where there may be some confusion about when you need to disinfect and when you just need a cleanser.”

Soap and water are safest for general cleaning, she added. Resources offer an alternative to harsh cleaning products. Disinfectants should generally be reserved for when someone has stomach flu or other illnesses for which disinfectants are effective, and even then they should not be “used unceremoniously,” Carignan said.

The paper highlights the need for regulators to protect consumers. Labeling requirements are inconsistent across product classes — they need to be listed on pesticide labels, they don’t need to be listed on paint labels, and appear to be only occasionally listed on disinfectant labels, Carignan says.

The paper calls on regulators to provide more clarity on chemicals, including more research on the health effects of quats, improved labeling and moving away from non-essential uses.

“Chemicals of concern should only be used when their action is necessary for health and safety, or is critical to the functioning of society, and no safer alternatives exist,” the study said.


‘No Mow May’ encourages homeowners to help bees by letting their lawns grow



let it grow

More than 70 cities in the US signed an agreement to ease maintenance rules for property owners in May, as part of a move to feed local bee populations for the upcoming growing season.

called “No mow may”, the initiative began in the United Kingdom and was later adopted by Appleton, Wisconsin, which became the first US city to implement it in 2020. let bee-friendly plants grow in their yards.

“Annoying weeds like clover and dandelions are like bee cheeseburgers,” said Israel Del Toro, an assistant professor of biology at Lawrence University and a city council member in Appleton.

According to Del Toro, Appleton saw the benefits of the bees. Since the start of the project, Appleton’s “No Mow May” lawns have shown a fivefold increase in bee numbers and a threefold increase in bee diversity compared to nearby parklands that were regularly mowed.

Bees are essential pollinators. Bees pollinate every year $15 billion harvest in the US and help farmers produce about third of all the food Americans eat.

But global bee populations are at risk — factors such as habitat loss, overuse of chemical pesticides and herbicides, disease and climate change could negatively impact bees, Del Toro said. globally, 35% invertebrate pollinatorsmainly bees and butterflies, are on the verge of extinction.

“If we can help the bees even a little, and not mow the lawns or give them extra food, that could make a big difference,” Del Toro said.

Without regular lawn mowing, homeowners also reduce the risk of soil damage from ground-nesting bees such as miner bees or leaf cutter bees, according to Relena Ribbons, an assistant professor of geosciences at Lawrence University.

An additional benefit of less mowing is the reduction of local air pollution. Because most lawnmowers run on gasoline, they can emit significant levels of air pollutants such as nitrogen oxides, carbon monoxide, particulate matter and carbon dioxide.

Angela Vanden Elzen, a librarian and lifelong resident of Appleton, said she rarely saw the bees in the city when they were growing.

“No Mow May gives us the opportunity to help our ecosystem effortlessly,” said Vanden Elzen. “I love sharing the project with my kids. It all started with honey bees, and now they have become more tolerant of all creatures, even spiders.”

Vanden Elsen’s seven-year-old daughter, Elora, said she enjoys participating in May Without Braids with her community.

“I’m excited about No Mow May because we feed the bees,” Elora said. “And I love seeing all the bright colors in my front yard and seeing the bees buzzing on the flowers.”

In other cities, residents have expressed concern that their lawns are not mowed. Jo Ann Lytvyn Clinton, Mayor of Orchard Park, New York raised a question attraction of ticks and rodents by neglected lawns. Orchard Park residents are currently debating whether mowing 2-foot by 2-foot areas is enough to stimulate bee populations.

At the University of Minnesota, a bee research group called the Bee Squad recommends practicing “Slow Mow Summer,” a method in which homeowners mow their lawns infrequently in the summer, keeping the grass at a moderately high height. Elaine Evans, a professor at the University of Minnesota and a researcher with the Bee Squad, said this strategy could help provide bees with food throughout the season, not just in May.

Matthew Normansel, an Appleton resident who runs Eden Wild Food, a wild food foraging and education business, said “No Mow May” is an important part of the solution.

“This is the first step towards realizing that our land and property are connected to the environment,” he said. “I don’t think it’s an answer, but it’s the start of an important conversation.”

Pancreatic cancer vaccine shows promise in small initial trial



Pancreatic cancer is one of the deadliest forms of cancer for which there are very few effective treatments. But messenger RNA (mRNA) vaccines, known for their ability to prevent COVID, are beginning to show some promise in the fight against deadly cancer. In a recent study, it helped early stage patients with pancreatic cancer who received personalized mRNA cancer vaccine after the operation there was no recurrence of the tumor in a year and a half. The trial, which was described in a study published Wednesday at Naturewhich was small—only 16 patients—and will need to be replicated in larger studies.

“I fully support the results,” says Drew Weissman, director of vaccine research and director of the RNA Innovation Institute at the University of Pennsylvania, a mRNA vaccine pioneer but not involved in the new paper. He adds that “this is not a definitive usability study. Larger studies are needed to determine effectiveness.”

Pancreatic ductal adenocarcinoma, the most common type of pancreatic cancer, has a mortality rate of 88 percent. It is the third leading cause of cancer death in the US and is becoming more common. Surgery is the main form of treatment, but cancer has a 90 percent recurrence rate within seven to nine months. Chemotherapy is only partially effective in delaying relapse. Other treatments, such as immunotherapy, are largely ineffective.

Pancreatic cancer often goes unnoticed until advanced stages, when it is more difficult to treat. One reason for its secretiveness is that it generates relatively few surface proteins called neoantigens that mark it as foreign and elicit an immune response. The scientists noticed that people who survived pancreatic cancer had a stronger response to these T cell neoantigens, a type of immune cell.

In a new study, Vinod Balachandran, an assistant surgeon at Memorial Sloan-Kettering Cancer Center in New York, and colleagues targeted the self-tumor neoantigens of pancreatic cancer patients using mRNA technology, the same technology that was used to create the hugely successful vaccines against COVID. The experimental vaccines used by Balachandran and his colleagues were produced by BioNTech, which developed one of the COVID vaccines with Pfizer. The researchers vaccinated a total of 16 patients. After surgical removal of tumors, they treated patients with mRNA vaccines tailored to each person’s specific cancer, as well as an adjuvant, a substance that enhances the effects of vaccines. Fifteen participants also completed chemotherapy.

Eight of 16 patients developed a strong T-cell response to the vaccines. With a mean follow-up of 18 months after treatment, these people had longer cancer-free survival.

The study was small and included only white patients. And therapy, which is expensive, doesn’t work for all pancreatic cancer patients. Still, experts say it’s a promising development for a disease with such limited treatment options.

5 best psychological theories of Sigmund Freud



This article was originally published on May 6, 2022.

When we tell our friends about a crazy dream we had with them, or when we use terms like ego and free association, we are referring to Sigmund Freud.

More than 80 years after his death, Freud’s theories about the human unconscious and how it affects our behavior continue to permeate Western culture. Freud’s pioneering psychological theories, presented to the world at the turn of the 20th century, changed our understanding of the human mind. His theories have influenced not only psychological theory, but also the way we behave in everyday life, in the family and at work. life.

Freud’s psychoanalytic theory

Terms like sleep analysis, free association, Oedipus complexthe Freudian slip and the ubiquitous ego, and id and superegowoven into much of what we do, think and say.

1. Sleep analysis

In modern society, we often talk about our dreams. If you google “dream quotes” there seems to be an endless supply of them. From bestselling author Erma Bombeck’s joke, “It takes a lot of guts to show your dreams to someone else,” to the American rapper and actor, Tupac Shakur lyrics, “Reality is wrong. Dreams are real.” But it is Freud who reveals what a dream is – an alternative reality that we experience when we sleep.

“The interpretation of dreams is the royal road to knowledge of the unconscious activities of the mind,” writes Freud.

Freud’s theory of dreams and his book The Interpretation of Dreams., were revolutionary. Before its publication in 1899, scientists considered dreams to be “meaningless”. Freud believed that dreams were “the disguised fulfillment of repressed childhood desires”.

While popular culture has taken Freud’s theories and applied their meaning – for example, dreams about flying mean that you are subconsciously thinking about ambition – Freud never wrote a dream dictionary. In fact, he shied away from such specifics. He insisted that although dreams are symbolic, they are specific to the individual and cannot be defined in general for the entire society.

2. Free association

Freud’s dream theories directly influenced his free association theory. Based on the theory that dreams and their meanings are individual, Freud allowed his patients to interpret their dreams for themselves, instead of giving them their own opinion. He called his process free association. With each new feature of a dream during a psychoanalytic session, Freud suggested that his patients relax and—to use a modern term—spit out what they thought it meant. Patients threw out ideas as they came, no matter how trivial they might be.

3. Reports on Freud

One of the most popular phrases from Freud’s theories: Freudian slip. He believed that a “slip of the tongue” – when we say something that we are not going to say – shows what we are thinking, subconsciously. Freud presented his theory of the Freudian slip in his 1901 book. Psychopathology of everyday life, and suggested that these verbal (and sometimes written) errors were rooted in “unconscious urges” and “unexpressed desires”. In addition, Freud believed that the inability to remember something – for example, someone’s address or name – is due to our need or desire to suppress it. Modern science has yet to explain why Freudian slips happen.

4. Oedipus complex, penis envy and womb envy

Experts believe Oedipus complex, psychosexual theory, as Freud’s most controversial theory. According to Freud, this is an unconscious desire that begins at the phallic stage of development, between the ages of three and six. The child is sexually attracted to its parent of the opposite sex and is jealous of its parent of the same sex.

Popular culture uses the Oedipus complex as a general term for the phase for both boys and girls. But Freud postulated that boys experience an Oedipus complex and girls an Electra complex. This is when a girl unconsciously becomes sexually attached to her father and is hostile to her mother.

Freud believed that the Oedipus complex was “the central phenomenon of the sexual period of early childhood”, but there is no scientific evidence to support his theory.

“Penis envy” grew out of Freud’s theory of the Oedipus complex, and Freud published it in 1908. Freud believed that a woman’s realization that she does not have a penis leads to intense envy, which underlies female behavior.

“Freud claimed that the only way to overcome this penis envy was to have a child of his own, and even went so far as to suggest that he wanted a male child in his efforts to gain a penis,” the researcher writes. British Psychological Society. Psychoanalyst Karen Horney, a contemporary of Freud whose theories led to the feminist psychology movement, saw penis envy as purely symbolic.

Horney postulated that envy, not of the phallus itself, but of the envy of the penis, had more to do with a woman’s position in society and “the desire for social prestige and position that men experience.” Thus, women felt inferior because of the freedom and social status they lacked because of their gender, and not because of their literal lack of a phallus,” the author writes. British Psychological Society.

In addition, Horney introduces the term “womb envy” and explains that men are negatively affected by their inability to have children and envy the “biological functions of the female sex”, including breastfeeding and pregnancy.

5. Ego, Id and Superego

Somebody think human psyche as the most enduring psychoanalytic theory in Freud’s career. Freud published his personality theory in 1923, which hypothesizes that the human psyche is divided into three parts – the ego, the id, and the superego. And they all develop at different stages of our lives. It is important to note that Freud believed that these are not physical objects in our brains, but rather “systems”.

While the word “ego” is used much more frequently in popular culture than “id” and “superego”, the three are related. According to Freud, the id is the most primitive part of the human psyche. This is the basis of our sexual and aggressive urges. The superego is our moral compass, and the ego is the judge, if you will, between the pulls of the id and the superego.

Freud’s psychological theories remain in our subconscious and consciousness

The next time you wake up from a strange dream that you can tell your best friend in detail, he will respond: “Oh, snakes? This dream is all about penis envy.” Or your boss yells at you and you mutter under your breath, “Too ego.” Or you are killing time on a long car ride and throwing away words and free associations – you have to thank Freud. And, if you’re looking for a reason to pay tribute to Freud and all of his contributions to our folk, pop culture and therapy, consider raising a toast to the father of psychoanalysis. He was born on May 6, 1856.
