What’s in tattoo ink? Chemical analysis performed by my team revealed ingredients that are not on the label and may cause allergies

Published

Tattoos are an especially common type of everlasting self-expression, dating back hundreds of years. Most tattoo artists adhere to strict health and sanitary regulations, so it may possibly be assumed that tattoo inks are also subject to detailed regulations.

But as work done by my team of chemistry researchers indicates, as much as 90% tattoo inks in the US may be mislabeled. It’s not nearly missing pigment or a minor discrepancy. These inks contained potentially disturbing additives that were not listed on the packaging.

What’s in the ink?

All inks consist of a number of pigments, i.e. the molecules that give tattoos color, and some variety of carrier for this pigment. Before the Twentieth century pigments used in tattooing contained ash, charcoal, minerals or other natural materials. However, around the mid-Twentieth century, tattoo artists began making their very own inks using synthetic pigments and dyes.

Today, just about all pigments used in tattoos are composed of synthetic molecules allowing for obtaining light colours – apart from white and black pigments.

Over the previous few many years, tattoo ink manufacturing has evolved from individual artists making their very own inks to large corporations producing inks and selling them to artists. My team desired to know if these inks contained the advertised ingredients, so we checked analyzed 54 tattoo inks from the American market.

Ingredients not listed

More than half of the inks my research team analyzed contained unlisted polyethylene glycol, also generally known as PEG. Diversity medical products contain PEG, including laxatives. May cause allergic reactionswhile in the case of tattooing, research suggests that repeated exposure to PEG can result in kidney failure.

We also found propylene glycol in 15 inks, even though it was not listed as an ingredient in any of them. Propylene glycol is mostly non-toxic and structurally much like glycerin, which is used to thicken ink. Although propylene glycol is secure for most individuals, some people are severely allergic to it. It was actually the American Contact Dermatitis Society Allergen of the Year 2018.

Some Allergic response propylene glycol may cause skin rash, itching and blistering.

In several of the inks, my research team found unlisted ingredients that are common in cosmetics but have not been tested for tattoo inks. These include BHT, dodecan AND 2-phenoxyethanol. In low concentrations, 2-phenoxyethanol is usually a preservative. But The Food and Drug Administration warns that it may possibly be passed on to babies through breastfeeding and cause vomiting and dehydration in children.

Of the 54 inks we reviewed, 29 reported correct pigments, while the rest reported either no pigments or incorrect pigments. This is understood problem with tattoo inks which ink manufacturers have not yet addressed.

Pigment problems

The research have shown that soot, the primary black pigment used in tattooing, may be contaminated with it cancer causing particles found in automotive exhaust fumes and cigarette smoke.

Many red, yellow and orange pigments are azo pigments, which contain two nitrogen atoms bonded. These pigments give the ink shiny, vibrant colours, but it will occur over time decompose into carcinogenic substances.

Regulations in Europe ban the copper-containing pigments Blue 15 and Green Pigment 7, which in line with my research are the only blue and green pigments in the inks we tested. The EU has banned the use of those pigments over concerns that they might be used in hair dyes may cause bladder canceralthough researchers have not yet studied this relationship in tattoos.

New emphasis on regulation

The FDA is beginning to pay more attention to what’s in tattoo inks. In 2022, Congress adopted Modernizing the Cosmetics Regulatory Act, or MoCRAwhich gave the FDA expanded authority to control tattoo inks.

FDA continues to be deciding tips on how to implement MoCRA, but the bill would require accurate ingredient labeling and expand FDA’s ink recall authority. In the past, tattoo inks were very rare and only voluntarily recalled for cause Bacterial contamination.

What does this mean for clients and tattoo artists? At the moment, there is no such thing as a clear research consensus on whether tattoos are secure or not because they’ll cause infections and allergic reactions. Additionally, tattoos vary greatly in size, color, and physical location on the body.

Studies like the one conducted in my lab are a vital a part of determining what’s actually in the tattoo, so researchers can higher understand any opposed events it may cause, resembling long-term allergic reactions.

Understanding the contents of the ink also helps doctors determine what specific health problems they need to search for in tattooed people.

Health problems related to tattoos that scientists are studying I learn about they arrive from unskilled artists following poor sanitation protocols. To prevent potential health problems, people considering getting a tattoo can work with an experienced and trained artist who follows best practices in tattoo hygiene and care.

We knew that detention at sea had a detrimental impact on the mental health of asylum seekers. Our new study shows exactly how bad

Published

on

By

For greater than a decade, mandatory offshore detention has been a cornerstone of Australia’s technique to deter people arriving by boat to assert asylum. This is followed by onshore detention, where people without a valid visa are held in transit centers and accommodation on mainland Australia.

Today we show the impact these policies have on the mental health of formerly detained asylum seekers.

Our new studythe largest study of its kind, shows high rates of post-traumatic stress disorder (PTSD), depression and suicidal thoughts amongst individuals who have been previously detained – especially at sea.

Our findings come at a time when several other countries are exploring their very own versions of offshore detention.

What we did

We surveyed 990 adult refugees and asylum seekers living in the Australian community between 2011 and 2018. These included 775 individuals who had never been held in a detention center and 215 who were detained and later released.

It is the largest known dataset available globally to measure the mental health of previously detained asylum seekers.

Some of the people in the detention center were held only on land, while others were held at sea after which transferred to a detention center on land.

Based on the survey participants’ responses, we determined the probable presence of mental disorders, including post-traumatic stress disorder (PTSD), depression and suicidal thoughts (intense and frequent thoughts about ending one’s life).

What we found

We found that incarceration significantly increases the risk of serious mental illness. People who had been in detention were more prone to later report symptoms of post-traumatic stress disorder, depression and suicidal thoughts in comparison with individuals who had not.

However, not all incarceration experiences carried the same degree of mental health risk.

People detained at sea were 16.5–20.2 times more prone to develop post-traumatic stress disorder, five times more prone to suffer from depression, and 4.6–5.2 times more prone to have suicidal thoughts in comparison with those detained on land for lower than six months.

The link between offshore detention and mental illness isn’t surprising. However, we were surprised by the scale of this effect.

Prolonged detention on land also had serious mental health consequences. People held on land for six months or longer were 16.9 times more prone to develop post-traumatic stress disorder and 5.5 times more prone to have suicidal thoughts in comparison with those held on land for lower than six months.

Our findings coincide with large body of research documenting the harmful psychological effects of detention on land (specifically for prolonged periods). However, for the first time we have now empirical data showing the much more harmful impact of detention at sea.

How did we get here?

Since 2012 4296 people they were held at sea on the island of Nauru or Manus under the supervision of the Australian government overseas processing policy.

It involves politics mandatory detention on land in detention and transit centers on mainland Australia.

Domestic and international courts have ruled that Australia’s practice of compulsory detention, particularly indefinite immigration detention and offshore detention, is against the law in some circumstances. The United Nations High Commissioner for Refugees has repeatedly called for an end to Australia’s offshore detention policy.

Despite this, detention at sea continues. Although all those remaining on Nauru in June 2023 were transferred to the Australian mainland, more people have since arrived. In September 2023, the Australian Government resumed transfers of individuals who arrived on Nauru by boat. The latest estimates suggest about 100 people were moved there.

However, research over the past decade has shown that detaining people at sea is each costly and ineffective. Analysis of migration patterns to Australia and other countries has shown that such policies don’t deter people from looking for asylum.

Detention at sea can also be expensive. It costs almost 22 million Australian dollars one yr for Australia to detain and interrogate one person at sea; the annual cost of managing the same person in the community could be $3,962.

Other countries must take this under consideration

Our findings have implications for other countries currently using similar models of offshore detention – often called “third-country processing.”

In February 2024 offshore processing transaction between Italy and Albania and in October 2024 these detention centers were ratified opened.

In April 2024, the UK passed this legislation relocating asylum seekers to Rwanda, a move that has been made repeatedly condemned by the United Nations. Despite the newly elected British Labor government promising to repeal the law in Julyit hasn’t happened yet. Instead, it looks like Britain is watching Agreement between Italy and Albania regarding asylum seekers with interest.

Denmark too resumed talks with Rwanda outsource the processing of data of people coming to Denmark to use for asylum. Recently also the Danish Minister of Immigration visited Nauru.

Actions by governments to keep up or establish offshore detention and processing policies are specifically at odds with clear evidence on the humanitarian and economic costs, and now clear evidence on the psychological burden of such practices.

There they’re evidence-based alternatives to be held at sea. These include timely and humane processing on land and supporting regional neighbors in providing friendly resettlement conditions for people looking for refuge from war and persecution.

Our findings strongly caution against continuing or establishing immigration detention policies that end in people being detained, particularly at sea or for longer periods of time.

Can you die from long Covid-19? The answer is not that simple

Published

on

By

Nearly five years into the pandemic, COVID seems less relevant to our each day lives.

However, the SARS-CoV-2 virus is still present, and for many individuals the consequences of the infection could also be long-lasting. When symptoms persist for greater than three months after the initial COVID infection, it is generally known as long Covid.

In September, a Brazilian musician and Grammy Award winner Sergio Mendes died on the age of 83 after reportedly long treatment for Covid-19.

Australian data show that 196 deaths were attributable to long-term effects of Covid-19 from the start of the pandemic to the top of July 2023.

In the United States, the Centers for Disease Control and Prevention reported 3,544 people long-term deaths related to Covid-19 from the start of the pandemic until the top of June 2022.

Symptoms long Covid – reminiscent of fatigue, shortness of breath and “brain fog” – could be debilitating. But can you die from long Covid? The answer is not that simple.

How long Covid can result in death?

We still don’t understand much about why the Covid virus has a long course. A well-liked theory is that “zombies” virus fragments they’ll linger within the body and cause inflammation even after the virus has gone, causing long-term health problems. Recent research suggests that this is a reservoir SARS-CoV-2 proteins within the blood may explain why symptoms persist in some people.

We know that a serious Covid infection may cause harm many organs. For example, it might result in severe Covid-19 everlasting lung dysfunctionpersistent heart inflammation, neurological damage and long-term kidney disease.

These problems can, in some cases, result in death immediately or months or years later. But is death after the acute phase of infection from considered one of these causes a direct results of COVID, long Covid-19, or something else? Whether long Covid-19 may cause death is still a subject of debate.

With 3,544 deaths related to long-term infection with the Covid-19 virus within the USA until June 2022, essentially the most continuously recorded cause was the Covid-19 virus itself (67.5%). This could mean they died from considered one of the long-term effects of Covid-19 infection, reminiscent of those listed above.

Covid-19 infection was followed by heart disease (8.6%), cancer (2.9%), Alzheimer’s disease (2.7%), lung disease (2.5%), diabetes (2%) and stroke ( 1.8%). Adults aged 75–84 had the very best rate of deaths related to long Covid-19 disease (28.8%).

These findings suggest that lots of these people died “from” long Covid-19, reasonably than from the disease. In other words, long Covid may not be a direct reason for death, but reasonably a contributing factor, possibly exacerbating existing conditions.

“Cause of death” is difficult to define

Long Covid is a comparatively recent phenomenon, so data on the mortality rate of individuals with the disease is limited.

However, we will draw some conclusions from the experiences of individuals suffering from post-viral diseases that have been studied longer, reminiscent of encephalomyelitis and chronic fatigue syndrome (ME/CFS).

How long Covid, ME/CFS is a fancy condition that can have a major and varied impact on an individual’s physical function, dietary status, social engagement, mental health and quality of life.

Some research shows that individuals with ME/CFS are in a difficult situation increased risk deaths from causes including heart disease, infections and suicide, which could also be triggered or worsened by the devastating nature of this syndrome.

So what does the emerging data on long Covid-19 tell us in regards to the potential increased risk of death?

Research from 2023 suggests that US adults with long-term Covid-19 infection were greater risk development of heart disease, stroke, lung disease and asthma.

Studies have also shown long Covid involves greater risk suicidal thoughts (pondering or planning suicide). This may reflect common symptoms and consequences of long Covid-19, reminiscent of sleep problems, fatigue, chronic pain and emotional distress.

However, long Covid-19 is more more likely to occur in individuals who have it existing health conditions. This makes it difficult to find out exactly how long the Covid-19 virus has been contributing to an individual’s death.

Research has shown this for a long time reliability problems in reporting causes of death, especially for people suffering from chronic diseases.

So what can we conclude?

Ultimately, long Covid is a chronic condition that can significantly impact your quality of life, mental well-being and overall health.

While the long-term Covid-19 virus is not often life-threatening or immediately life-threatening, it is possible that it could exacerbate existing health conditions and thus contribute to an individual’s death.

Importantly, many individuals all over the world with long-term Covid-19 do not have access to adequate support. We need to develop care models for optimal management of individuals suffering from long-term Covid-19 disease, with particular emphasis on multidisciplinary care.
