It’s no secret: when having fun with a delicious piece of fish or a platter of seafood, we devour not only useful omega-3 acids and vitamin D. In addition to these advantages, there are less appetizing elements – countless micro- and nanoplastics.

These plastic particles, measuring lower than 5 millimeters in size, enter our oceans through human waste and enter the food chain. According to Ifremer’s studyThere are roughly 24,400 billion microplastics floating on the ocean surface. These molecules are present in all marine life, from microalgae to fish, which occupy the higher levels of the food chain. This phenomenon not only threatens marine ecosystems, but additionally raises concerns about potential threats to human health.

What exactly can we learn about the accumulation of those pollutants in marine organisms and the risks they pose to human health?

Micro- and nanoplastics: an invisible threat

Since the Fifties, plastic production has increased exponentially, reaching 58 million tons in Europe only in 2022. This has led to the creation of giant amounts of waste.

Over time, wind, waves, sunlight and microorganisms break down larger plastic waste into microplastics (1-5 mm) and nanoplastics (smaller than 100 nanometers), which now pollute all parts of the environment, including air, soil and water.

The process by which these plastics accumulate in organisms at various levels of the food chain is known as “bioaccumulation”.

Research from our laboratory reveals that in aquatic environments, micro- and nanoplastics are consumed by a wide selection of species – from microalgae at the base of the food chain to top predators resembling eels.

Impact on marine life

Such consumption has serious consequences. Studies show that microplastics may cause toxic effects on marine animals.

In mussels, for instance, microplastics can clog the digestive system, activate immune responses, cause DNA damage, and disrupt the expression of genes mandatory for various cellular functions.

The severity of those effects relies on the size, composition, degree of degradation and harmful chemical additives that plastics may contain.

Plastics often contain large amounts of phthalates, which disrupt the functioning of the endocrine system. These chemicals can disrupt the endocrine system, posing a risk not only to marine life, but potentially to humans as well.

Risks to human health

Plastics ingested by marine animals inevitably find yourself in our food.

Frequent seafood consumers are estimated to ingest hundreds of microplastic particles annually. Although research into the exact effects on human health is ongoing, some disturbing hypotheses have emerged.

Once in the human body, these particles may cause damage similar to that observed in fish.

Studies on human cells indicate this micro- and nanoplastics may cause interference cellular functions in a fashion similar to the effects seen in marine organisms. Scientists are particularly concerned about the toxic effects of plastic additives.

Additionally, micro- and nanoplastics can act as carriers of pathogens or bacteria, potentially increasing the risk of infectious diseases.

The urgent need to address the bioaccumulation of plastics in the food chain can’t be overemphasized. By taking quick motion to reduce plastic use and improve recycling technologies, we are able to slow the progression of the environmental and health crisis.

Why pain assessment at 10 is difficult

Published

on

By

“This is really sore,” said my (Josh) five-year-old daughter, swaying a broken arm within the emergency department.

“But on a zero scale, how do you assess your pain?” The nurse asked.

The face of my daughter, fire to tears, deepened his confusion.

“What does ten mean?”

“Ten is the worst pain you can imagine.” She looked much more surprised.

As a parent and a scientist with pain, I witnessed how our seemingly easy, well -intentional pain assessment systems can fall flat.

What are the scales of pain for?

The commonest scale has existed in 50 years. He asks people to evaluate pain from scratch (without pain) to 10 (normally “the worst pain you can imagine”).

Advertisement

He focuses on one aspect of pain – its intensity – to quickly understand the patient’s entire experience.

How much does it hurt? Are you getting worse? Does treatment make it higher?

Grades could be useful to trace the intensity of pain in time. If the pain goes from eight to 4, it probably signifies that you’re feeling higher – even when someone’s 4 are different than yours.

The research suggests a two -point (or 30%) reduction in chronic pain in pain normally reflects the change makes a difference in on a regular basis life.

But this common upper anchor within the assessment scales – “the worst pain you can imagine” – is an issue.

People normally seek advice from their previous experiences when assessing pain.

A narrow tool for complex experience

Consider my daughter’s dilemma. How can someone imagine the worst possible pain? Does everyone imagine the identical? Research suggests that they usually are not. Even Children think very individually about this word “pain”.

People normally – and comprehensible – anchor their pain assessments in their very own life experiences.

This creates a dramatic variety. For example, a patient who has never had serious injuries could also be more willing to provide high grades than the one who had serious burns before.

“No pain” may also be problematic. A patient whose pain has gone back, but who stays uncomfortable may get stuck: there is no number on a zero scale to 10, which may capture their physical experience.

Increasingly, pain scientists recognize an easy number cannot capture complex, highly individual and multi -faceted experience, which is pain.

Who we’re, affects our pain

In fact, pain assessment They are under influence How much pain disturbs an individual’s each day activities, as they’re nervous, their mood, fatigue and the way it is in comparison with their strange pain.

Other aspects also play a job, including the patient’s age, gender, cultural origin and language, reading and counting skills, and neurodiwe.

For example, if a clinician and patient speak different languages, it might probably exist Additional challenges Communication about pain and care.

Some people neurodivergent may interpret the language more literally or process sensory information differently than others. Interpretation of what people communicate About pain requires a more personalized approach.

Impossible assessments

Still, we work with available tools. There is evidence People use the size of zero-to ten pain to attempt to convey far more than simply Paer’s “intensity”.

So when the patient says “it’s eleven out of ten”, this “impossible” assessment probably communicates with something greater than severity.

Perhaps they wonder: “Does she believe me? What number will help me? “A whole lot of information is crowded on this single number. This patient probably says: “This is serious – help me.”

We use quite a few other communication strategies in on a regular basis life. We can grimace, moan, move less or in a different way, use richly descriptive words or metaphors.

Collecting and assessing such a complex and subjective information on pain may not all the time be feasible since it is difficult to standardize.

As a result, many pain scientists still largely depend on the assessment scales, because they’re easy, efficient and turned out to be reliable and necessary in relatively controlled situations.

But clinicians may use this other, more subjective information to construct a more complete picture of an individual’s pain.

How can we higher communicate about pain?

There are strategies to unravel Language or cultural differences In how people express pain.

Visual scales are one tool. For example, “directed on a scale of pain” asks patients to decide on a facial features to convey pain. This could be especially useful for youngsters or individuals who don’t feel comfortable at all with counting and the flexibility to read, or in a language utilized in the healthcare environment.

The vertical “visual analog scale” asks an individual to mark pain on the vertical line, a bit like a picture “Filling” with pain.

What can we do?

Healthcare employees

Time to consistently explain the size of pain, remembering that The way you phrase matters.

Listen to the story behind the number, because the identical number means various things for various people.

Use the rating as a startup to get a more personalized conversation. Consider cultural and individual differences. Ask for descriptive words. Confirm your interpretation within the patient to be sure you might be each on the identical side.

Patients

To higher describe the pain, use the size of numbers, but add context.

Try to explain the standard of your pain (smoking? Pulsating? Styling?) And compare it with previous experiences.

Explain the influence of you pain – each emotionally and the way it affects your each day activities.

Parents

Ask the clinicist to make use of the permissible pain of youngsters. They are there Special tools developed for various age groups reminiscent of “He will turn to pain“.

Pediatric health specialists are trained to make use of vocabulary suitable for age, because children develop their understanding of the number and pain otherwise after they grow.

Starting point

In fact, scales won’t ever be great measures of pain. Let’s see them as participating within the conversation to assist people communicate about deeply personal experience.

This is how my daughter did – she found her method to describe her pain: “I think that when I fell from monkeys, but in my arm instead of my knee, and it’s not better when I stay.”

From there, we tried to treat with pain effectively. Sometimes words work higher than numbers.

When the singer Muni Long doesn’t bless us with timeless hits, he fights lupus pain behind closed doors. Chronic autoimmune disease causes exacerbation that affects every person otherwise. For the 36-year-old, symptoms sometimes appear in her skin, she said in an exclusive interview.

“[People with lupus] You have small characters, right? Like my fingertips, blue will change. My skin will be really pale, “says Long. “I’ll start looking great white. It’s hard to imagine because I’m brown. But literally my skin becomes like a light, gray color. “

Around 1 out of 250 Black women will develop lupus during their lives and experience it more seriously. While Long can manage some flashes and proceed to occupy their day by day lives, some disrupt its entire schedule.

“Recently, I had to cancel my football performance in university football on January 18, because I had development because of some personal items,” Long explained.

The two -time Grammy winner also needed to take preventive measures in order that her lupus doesn’t negatively affect her ability to sing. When the singer joined Chris Brown as an opener to his route 11:11 last summer, she needed to take some means to stop her symptoms.

“Please, turn off the air when I come to the building. I am not a diva, but literally, if I am too cold, I start coughing and I will not be able to sing, “he divides Long. “And then, when I get off the stage, I have to lie down immediately and surround the covers and steam in hand.”

Despite the proven fact that he’s a star, Long faces similar challenges as other black women in regards to the healthcare system. Black women often encounter significant health differences in relation to other racial groups. This can fluctuate from receiving unfair treatment after ignoring when causing problems related to pain or discomfort.

“As a black woman, when I go to the doctor, they never listen,” said Long, asked how lupus influences her everyday. “They don’t believe you. It is difficult for them to say, “Hey, I’m in pain.” They are like: “Ok, cool. Go, get this blood work. “

She continued: “I am like:” OK, but it would take you per week [to get the results back.] I’m in tormenting pain. Is there anything you’ll be able to do? And then it just becomes something prefer it as in the event that they put your list away [something] For example: “Oh, you are asking for medicines.” It is in order that such difficult navigation with the way in which the healthcare system is configured. “

For now, the singer focuses on managing the extent of stress, because this may cause her flares.

“The point is that I really have to not let people stress me, which is difficult because people get into my nerves,” says Long with amusing. “So the best tool I have is just relaxing and not doing anything I don’t want to do. We make every effort to make sure that such things have not happened and before I enter the space, I can be as convenient as possible. “

If you are fascinated by referring the range of products on the shelf in the lavatory, you may start by throwing the entire.

AND New study By Environmental work group (EEC) In cooperation with the founded black, completely natural online market BLK + GRN Over 3000, or almost 80%, were found, personal hygiene items sold to black women contain at the very least one toxic ingredient.

“I think most people believe that if something has reached the store, they must be safe. It’s just not true – said the founder of BLK + GRN, Kristian Edwards In the last film About the report.

“Everyone deserves access to safe products,” wrote Friedman. “The purpose of the report was to equip consumers with knowledge about chemicals in their personal hygiene products.”

Friedman emphasized among the most harmful product components, including the discharge of formaldehyde, isotiazolinone and an undisclosed smell. Explained that preservatives releasing formaldehyde may cause skin reactions and ultimately expose consumers to formaldehyde, a carcinogen. Meanwhile, Friedman noticed that undisclosed fragrances might be any of the 300 different potentially dangerous ingredients with cancer and reproductive health problems. Half -lasting products The results, comparable to relaxors and hair dyeing, are not very disturbing.

After the primary have a look at ListMany consumers can hurry to throw away all their potentially causing cancer shelf. However, Edwards noticed within the film that this list was not intended to cause “fear”.

Understanding this suggested compromise. If there may be a high-level product, with which you absolutely cannot part-nutrition with the outcomes that you have got taken years, or sunscreen that softened your gearbox-to threaten something different with a high level, from which your routine is less dependent.

“Black women are often between a stone and a difficult place,” Edwards continued. “To adapt, they must use these products with all these toxic ingredients in them.”

The Skin Deep Database EEC launched in 2004 takes labor in the method for consumers. The online resource includes dozens of products assessed on the idea of their ingredients, safety and regulatory information.

The latest study, published in February, is an update of the 2016 EEC study, which was checked whether there was a significant change in toxicity of products with specific demographic markings. In 2016, the report was analyzed by just over 1000 products. Despite finding almost 80% of products sold to black women, it still incorporates at the very least one toxic ingredient, Friedman confirmed that there was some improvement in almost a decade; However, toxicity persists.

The report also appears as one other related to black personal care, it’s headers. Last month, Consumer reports He stated that the ten hottest synthetic hair brands contain toxic chemicals.

Friedman claims that the trail forward should “prioritize further research, better safety standards and increased transparency from producers, ultimately supporting the market in which black women can confidently choose products without an additional burden on the disorientation of exposure and health results.”
