When children are told they were born via assisted reproduction can affect outcomes, study finds | CNN

At age 14, Helen wasn’t bothered by the fact she was born via surrogacy.

“My mum is still my mum. My dad is still my dad,” she told UK researchers conducting a study on the mental health and well-being of children born through egg donation, sperm donation and surrogacy. Helen is not her real name.

“I was talking to someone at school and they said they were an accident,” 14-year-old Simon (also not his real name) told the researchers. “I know I was no accident, I was really wanted, and it makes me feel special.”

Parents worried their children may experience difficulties as a result of learning they were conceived by assisted reproduction can stop fretting — the kids are just fine, according to the study published this week after two decades in the making.

“When we began this study more than 20 years ago, there was concern the absence of a biological link between the child and the parents could have a damaging effect on their relationship and on the well-being of the child,” said lead author Susan Golombok, professor emerita of family research and former director of the Centre for Family Research at the University of Cambridge in the UK.

However, at age 20, children born via egg or sperm donation and surrogacy were psychologically well-adjusted, the study found, especially if parents told the children about their birth history before age 7.

“What this research means is that having children in different or new ways doesn’t actually interfere with how families function. Really wanting children seems to trump everything — that’s what really matters,” Golombok said.

Clinical psychologist Mary Riddle, an associate professor of psychology at Pennsylvania State University called the study “important, in that it represents research conducted over a long period of time.”

However, Riddle, who was not involved in the study, said the results aren’t completely applicable to the United States because surrogacy can be practiced differently in the UK in several ways.

Called “tummy mummies” by some of the children, surrogates in the UK may become part of the family, participating in the upbringing of the child they helped bring into the world, according to Golombok’s 2020 book, “We Are Family: The Modern Transformation of Parents and Children.”

“In the UK, intended parents often know their surrogate prior to the surrogate pregnancy whereas in the US, commercial surrogates are often matched through agencies and don’t have prior relationships with the families for whom they carry babies,” Riddle said.

It’s also more common in the UK to use “partial” surrogacy, in which surrogates are impregnated with the sperm of the intended father and are therefore the biological mother of the child, Riddle said.

“Here in the US, gestational surrogacy, where the surrogate mother has no genetic connection to the child she is carrying, is far more common and thought to be potentially less fraught with psychological and legal pitfalls,” she added.

The study, published Wednesday in the journal Developmental Psychology, followed 65 children — 22 born by surrogacy, 17 by egg donation and 26 by sperm donation — from infancy until age 20. Another 52 families who did not use any assistance were also followed. Researchers spoke to the families when the children were 1, 2, 3, 7, 10 and 14.

Young adults who learned about their biological origins before age 7 reported better relationships with their mothers, and their mothers had lower levels of anxiety and depression, the study found.

However, children born through surrogacy had some relationship issues around age 7, “which seemed to be related to their increased understanding of surrogacy at that age,” Golombok said.

“We visited the families when the children were 10, and these difficulties had disappeared,” she said. “Interestingly, the same phenomenon has been found among internationally adopted children. It may have to do with having to confront issues of identity at a younger age than other children.”

Developmentally, children begin to notice and ask questions about pregnancy between the ages of 3 and 4, said clinical psychologist Rebecca Berry, an adjunct faculty member in the department of child and adolescent psychiatry at New York University’s Grossman School of Medicine.

“To satisfy their curiosity they’ll begin to ask questions about babies and where they came from as a way of trying to understand why they are here,” said Berry, who was not involved with the study.

Children as young as 7 will already have a basic understanding of genetics, and can be surprised when they learn they aren’t genetically connected to one or both parents, said Lauri Pasch, a psychology professor at the University of California San Francisco, who specializes in infertility and family building.

“Our current thinking is that it is best for parents to share the story of donor conception with their children at a very early age, so that if I were to ask their child when they are an adult when they learned that they were donor conceived, they would respond that they ‘always knew,’” said Pasch, who was also not involved in the study, via email.

“This allows the child to grow up with the information, as opposed to learning it later in life, when it comes as a surprise or shock and can hurt their trust in their parents and their identity development,” she added.

When it came to maternal anxiety and depression, there were no differences between families formed by surrogacy and egg or sperm donation and families with children born without assisted conception. Nor were they any differences in the mothers’ relationships with their partners at home, the study found.

However, mothers who had babies via donor eggs reported less positive family relationships than mothers who used sperm donation, likely due to insecurities about lack of a genetic connection to their children, Golombok said.

Young adults conceived by sperm donation reported poorer family communication than those conceived by egg donation, the study found. That’s perhaps due to a greater reluctance on the part of fathers to disclose they are not a genetic parent, Golombok said.

Only 42% of parents who had conceived via sperm donor had revealed the child’s birth history by the time their children were age 20, compared to 88% of egg donation parents and 100% of parents who used surrogacy.

When asked, many of the children said they weren’t concerned about how they were conceived.

“A lot of the children said ‘It’s not a big deal. I’ve got more interesting things going on in my life,’ while others said ‘Actually it’s something a bit special about me. I like talking about it,’ Golombok said. “I think it’s really nice to hear from the children themselves and I don’t think any other study has done this.”

Once told, a child needs to revisit the birth history from time to time, so parents should be sure any conversation is an ongoing one, Golombok said.

“There is this idea parents will tell the child and that is it. But you need to keep having these conversations to give the child a chance to ask questions in an age appropriate way as they grow older,” she said.

“Many of the parents in our study use children’s books that were specifically designed for this purpose,” Golombok added. “Then they could bring the child’s own story into the narrative.”

100,000 newborn babies will have their genomes sequenced in the UK. It could have big implications for child medicine | CNN



CNN
 — 

The UK is set to begin sequencing the genomes of 100,000 newborn babies later this year. It will be the largest study of its kind, mapping the babies’ complete set of genetic instructions, with potentially profound implications for child medicine.

The £105 million ($126 million) Newborn Genomes Programme will screen for around 200 rare but treatable genetic conditions, with the aim of curtailing untold pain and anxiety for babies and their families, who sometimes struggle to receive a diagnosis through conventional testing. By accelerating the diagnostic process, earlier treatment of infants could prevent many severe conditions from ever developing.

The study would see roughly one in 12 newborn babies in England screened on a voluntary basis over two years. It will operate as an extension of current newborn testing, with the findings intended to inform policymakers, who could pave the way for sequencing to become more commonplace.

Nevertheless, the project has raised many longstanding ethical questions around genetics, consent, data privacy, and priorities within infant healthcare.

In the UK, like many other countries, newborn babies are screened for a number of treatable conditions through a small blood spot sample. Also known as the heel prick test, this method has been routine for over 50 years, and today covers nine conditions including sickle cell disease, cystic fibrosis and inherited metabolic diseases.

“The heel prick is long overdue to be obsolete,” argues Eric Topol, an American cardiologist and professor of molecular medicine at The Scripps Research Institute, who is not connected with the UK sequencing initiative. “It’s very limited and it takes weeks to get the answer. Sometimes, babies that have serious metabolic abnormalities, they’re already being harmed.”

Some conditions that are tested for have variations that may not register a positive result. The consequences can be life-altering.

One example is congenital hyperthyroidism, which impacts neurological development and growth and affects “one in 1,500 to 2,000 babies in the UK,” explains Krishna Chatterjee, professor of endocrinology at the University of Cambridge. It is the result of an absent or under-developed thyroid gland and can be treated with the hormone thyroxine, a cheap and routine medicine. But if treatment doesn’t begin “within the first six months of life, some of those deleterious neurodevelopmental consequences cannot be prevented or reversed.”

The Newborn Genomes Programme will test for one or more forms of congenital hypothyroidism that are not picked up by the heel prick test. “At a stroke, you can make a diagnosis, and that can be game changing – or life changing – for that child,” Chatterjee says.

The program is led by Genomics England, part of the UK Department of Health and Social Care. Along with its partners, it has carried out a variety of preparatory studies, including a large-scale public consultation. A feasibility study is currently underway to assess whether a heel prick, cheek swab or umbilical cord blood will be used for sampling, with the quality of the DNA sample determining the final choice.

Genomics England says that each of the 200 conditions that will be screened for has been selected because there is evidence it is caused by genetic variants; it has a debilitating effect; early or pre-symptomatic treatment has a life-improving impact; and treatment is available for all through the UK’s National Health Service (NHS).

Richard Scott, chief medical officer and deputy CEO at Genomics England, says the program aims to return screening results to families in two weeks, and estimates at least one in 200 babies will receive a diagnosis.

Contracts for sequencing are still to be confirmed, although one contender is American biotech company Illumina. Chief scientist David Bentley says the company has reduced the price of its sequencing 1,000-fold compared to its first genome 15 years ago, and can now sequence the whole human genome for $200.

Bentley argues that early diagnosis via genome sequencing is cost effective in the long term: “People get sick, they get tested using one test after another, and that cost mounts up. (Sequencing) the genome is much cheaper than a diagnostic odyssey.”

Illumina equipment in a sequencing laboratory. The cost of sequencing the human genome has fallen significantly in the last 15 years, says the company.

But while some barriers to genetic screening have fallen, many societal factors are still in play.

Feedback from a public consultation ahead of the UK project’s launch was generally positive, although some participants voiced concerns that religious views could affect uptake, and a few expressed skepticism and mistrust about current scientific developments in healthcare, according to a report on its findings.

Frances Flinter, emeritus professor of clinical genetics and Guy’s and St Thomas’ NHS Foundation Trust and a member of the Nuffield Council on Bioethics, described the program as a “step into the unknown” in a statement to Science Media Centre in December 2022, reacting to the launch of the program.

“We must not race to use this technology before both the science and ethics are ready,” she said at the time. “This research program could provide new and important evidence on both. We just hope the question of whether we should be doing this at all is still open.”

Genome sequencing has raised many philosophical and ethical questions. If you could have aspects of your medical future laid ahead of you, would you want that? What if you were predisposed to an incurable disease? Could that knowledge alone impact your quality of life?

“People don’t generally understand deterministic or fatalistic-type results versus probabilistic, so it does require real teaching of participants,” says Topol. In other words, just because someone has a genetic predisposition to a certain condition, it doesn’t guarantee that they will develop the disease.

Nevertheless, sequencing newborn babies has made some of those questions more acute.

“One of the tenets of genomics and genomics testing is the importance of maintaining people’s autonomy to make their own decisions,” says Scott, highlighting the optional nature of the program.

“We’ve been quite cautious,” he stresses. “All of the conditions that we’re looking for are ones where we think we can make a really substantial impact on those children’s lives.”

Parents-to-be will be invited to participate in the program at their 20-week scan, and confirm their decision after the child’s birth.

“These will be parents, most of whom won’t have any history of a genetic condition, or any reason to worry about one. So it will be an additional challenge for them to appreciate what the value might be for their family,” says Amanda Pichini, clinical lead for genetic counseling at Genomics England.

Part of Pichini’s remit is to ensure equal access to the program and to produce representative data. While diversity comes in many forms, she says – including economic background and rural versus urban location – enlisting ethnically diverse participants is one objective.

“(There) has been a lack of data from other ethnic groups around the world, compared to Caucasians,” says Bentley. “As a result, the diagnostic rates for people from those backgrounds is lower. There are more variants from those backgrounds that we don’t know anything about – we can’t interpret them.”

If genomics is to serve humanity equally, genome data needs to reflect all of it. Data diversity “isn’t an issue that any one country can solve,” says Pichini.

Other countries are also pursuing sequencing programs and reference genomes – a set of genes assembled by scientists to represent a population, for the purpose of comparison. Australia is investing over $500 million AUS (around $333 million) into its genome program; the “All of Us” program is engaged in a five-year mission to sequence 1 million genomes in the US; and in the Middle East, the United Arab Emirates is seeking its own reference genome to investigate genetic diseases disproportionately affecting people in the region, where Illumina’s recently opened Dubai office will add local sequencing capacity.

Richard Scott of Genomics England says he hopes findings from the UK will be useful to other countries’ health systems, especially those not in “a strong position to develop the evidence and to support their decisions as well.”

Sequenced genomes will enter a secure databank using the same model as the National Genomic Research Library, in which they are deidentified and assigned a reference number.

Researchers from the NHS, universities and pharmaceutical companies can apply for access to the National Genomic Research Library (in some cases for a fee), with applications approved by an independent committee that includes participants who have provided samples. There are plenty of restrictions: data cannot be accessed for insurance or marketing purposes, for example.

“We think it’s really important to be transparent about that,” says Pichini. “Often, drugs and diagnostics and therapeutics can’t be developed in the NHS on (its) own. We need to have those partnerships.”

When each child turns 16, they will make their own decision on whether their genomic data should remain in the system. It hasn’t yet been decided if participants can request further investigation of their genome – beyond the scope of newborn screening – at a later date, says Scott.

After the two-year sampling window closes, a cost-benefit analysis of the program will begin, developing evidence for the UK National Screening Committee which advises the government and NHS on screening policies. It’s a process that could take some time.

Chatterjee suggests an entire lifetime might be needed to measure the economic savings that would come from early diagnosis of certain diseases, citing the costs of special needs schooling for children and support for adults living with certain rare genetic conditions: “How does that balance against the technical cost of making a diagnosis and then treatment?”

“I’m quite certain that this cost-benefit equation will balance,” Chatterjee adds.

Multiple interviewees for this article viewed genome sequencing as an extension of current testing, though stopped short of suggesting it could become standard practice for all newborn babies. Even Topol, a staunch advocate for genomics, does not believe it will become universal. “I don’t think you can mandate something like this,” he says. “We’re going to have an anti-genomic community, let’s face it.”

Members of the medical community have expressed a variety of concerns about the program’s approach and scope.

In comments released last December, Angus Clarke, clinical professor at the Institute of Cancer and Genetics at Cardiff University, queried if the program’s whole genome sequencing was driven by a wish to collect more genomic data, rather than improve newborn screening. Louise Fish, chief executive of the Genetic Alliance UK charity, questioned whether following other European nations that are expanding the number of conditions tested through existing bloodspot screening may have “just as great an ability to improve the lives of babies and their families.”

If genome sequencing becomes the norm, it remains to be seen how it will dovetail with precision medicine in the form of gene therapy, including gene editing. While the cost of sequencing a genome has plummeted, some gene therapies can cost millions of dollars per patient.

But for hundreds of babies not yet born in England, diagnosis of rare conditions that have routine treatments will be facilitated by the Newborn Genomes Programme.

“So much of medicine today is given in later life, and saves people for a few months or years,” says Bentley. “It’s so good to see more opportunity here to make a difference through screening and prevention during the early stages of life.

“It is investing maximally in the long-term future as a society, by screening all young people and increasing their chances of survival through genetics so they can realize their enormous potential.”

Common kinds of air pollution led to changes in teens’ blood pressure, study says | CNN



CNN
 — 

Scientists know that air pollution can make it difficult to breathe and may ultimately cause serious health problems like cancer, but a new study shows that it might also have a negative impact on teens’ blood pressure.

Exposure to higher levels of nitrogen dioxide was associated with lower blood pressure in teens, according to the study, published Wednesday in the journal PLOS One. Exposure to particulate matter 2.5, also known as particle pollution, was associated with higher blood pressure.

The researchers say the impact is “considerable.”

Other studies have found a connection between blood pressure changes and pollution, but much of that work focuses on adults. Some research has also found negative associations with pollution exposure and younger children, but little has focused on teens.

Generally, low blood pressure can cause immediate problems like confusion, tiredness, blurred vision and dizziness. High blood pressure in adolescence can lead to a lifetime of health problems including a higher risk of stroke or heart attack. It’s a leading risk factor for premature death worldwide.

The study did not look at whether the teens had symptoms or health effects from the change in blood pressure.

The scientists saw this association between pollution and blood pressure in data from the Determinants of Adolescent Social Well-Being and Health study, which tracks the health of a large and ethnically diverse group of children in London over time.

The researchers took data from more than 3,200 teens and compared their records to their exposures to pollution based on annual pollution levels where they lived.

Nitrogen dioxide pollution is most commonly associated with traffic-related combustion byproducts. Nitrogen may help plants grow, but it can impair a person’s ability to breathe and may cause damage to the human respiratory tract. In this study, the nitrogen was thought to be coming predominantly from diesel traffic.

The particle pollution in the study is so tiny – 1/20th of a width of a human hair – that it can travel past the body’s usual defenses. Instead of being carried out when a person exhales, it can get stuck in the lungs or go into the bloodstream. The particles cause irritation and inflammation and may lead to a whole host of health problems.

Particle pollution can come from forest fires, wood stoves, power plants and coal fires. It can also come from traffic and construction sites.

In this study, the link between pollution exposure and changes in blood pressure was stronger in girls than in boys. The researchers can’t determine why there is a gender difference, but they found that 30% of the female participants got the least amount of exercise among the group and noted that that can have an effect on blood pressure.

“It is thus imperative that air pollution is improved in London to maximise the health benefits of physical exercise in young people,” the study says.

Although the study also can’t pinpoint why teens’ blood pressure changed with pollution exposure, others have found that exposure to air pollution may affect the central nervous system, causing inflammation and damage to the body’s cells. Additionally, exposure to particle pollution can disrupt a person’s circadian rhythms, which could affect blood pressure. Particle pollution exposure may also reduce the kidneys’ ability to excrete sodium during the day, leading to a higher nighttime blood pressure level, the study says.

When it came to nitrogen dioxide pollution, the researchers had previously done a crossover study that involved the blood pressure of 12 healthy teen participants who were exposed to nitrogen oxide from a domestic gas cooker with lit burners. Their blood pressure fell compared with participants exposed to only room air.

In the new study, the associations between pollution and blood pressure were consistent. Body size, socieoecomonic status and ethnicity didn’t change the results.

However, it looks only at teens in London, and only 8% of them were people of color. Those children were exposed to higher levels of pollution than White children, the study found.

Levels of pollution in London are also well above what World Health Organization guidelines suggest is safe for humans. However, the same could be said for most any area in the world. In 2019, 99% of the world’s population lived in places that did not meet WHO’s recommended air quality levels.

Earlier work has shown that pollution can damage a young person’s health and may put them at a higher risk for chronic diseases like heart problems later in life. Studies in adults found that exposure to air pollution can affect blood pressure even within hours of exposure.

Pollution caused 1 in 6 deaths worldwide in 2019 alone, another study found.

Some experts suggest that one way to reduce a teen’s risk of pollution-related health problems is to invest in portable air cleaners with HEPA filters that are highly effective at reducing indoor air pollution. However, the filters can’t remove all of the problem, and experts say communitywide solutions through public policy are what’s needed.

Dr. Panagis Galiatsatos, an assistant professor in pulmonary and critical care medicine at Johns Hopkins Medicine, said research like this is important to generate a hypothesis about what these pollutants are doing to people. Galiatsatos, a volunteer medical spokesperson with the American Lung Association, was not involved with the new study.

“A lot of these air pollutions tend to cluster in economically disadvantaged neighborhoods, so it’s one of the big reasons we want to always keep a close eye on this, as it disproportionately impacts certain populations more than others,” he said.

Blood pressure is an important marker to track for health because it is a surrogate to understand the more complex processes that might be happening in the body.

“My big takeaway is that these toxins clearly seem to have some physiological impact on the cardiovascular system, and any manipulation should be taken into the context of a concern,” Galiatsatos said.

Study co-author Dr. Seeromanie Harding, a professor of social epidemiology at King’s College London, said she hopes it will lead to more research on the topic.

“Given that more than 1 million under 18s live in [London] neighborhoods where air pollution is higher than the recommended health standards,” she said in a news release, “there is an urgent need for more of these studies to gain an in-depth understanding of the threats and opportunities to young people’s development.”

Scotland recognized as world’s best golf destination | CNN




CNN
 — 

It remains to be seen whether football will come home for England at the World Cup in Qatar next month, but for neighboring Scotland, golf has officially – and finally – returned to its motherland.

Having hosted the game for almost six centuries, “the home of golf” – as Scotland is known – was recognized as the World’s Best Golf Destination for the very first time at the ninth edition of the annual World Golf Awards in Abu Dhabi this week.

Despite the dominance of its legendary St. Andrews Old Course in the World’s Best Golf Course category – with five successive wins after the award’s inception – Scotland had never been recognized as the sport’s best destination.

Portugal had held an iron grip on the title for the award’s first five years, before a victory for Australia was sandwiched between wins for Vietnam in 2019 and 2021.

Yet after a landmark year, which saw Scottish links courses play host to two historic majors – the 150th Open Championship at St. Andrews and the first ever Women’s Open at Muirfield – the country finally scooped the prize, as well as the award for Best Golf Destination in Europe.

The sole European contender for the World award, Scotland trumped rival nominees Argentina, Australia, Canada, Dubai, Jamaica, Morocco, and last year’s winner Vietnam.

Scotland’s golf industry is worth upwards of $1.3 billion (£1.1 billion), with an annual golf tourism market bringing in $339 million (£286 million) and supporting over 4,000 jobs, according to Visit Scotland.

“These awards are a fitting end to an extra special year for golf in Scotland and fantastic recognition for all the people who work so hard to grow and enhance our reputation as The Home of Golf,” said Visit Scotland Chief Executive Malcolm Roughead.

“Golf tourism is a significant boost for the economy and raises Scotland’s profile on the international stage.”

In October, the fabled Alfred Dunhill Links Championship saw professionals and celebrities alike rotate around St. Andrews, Carnoustie and Kingsbarns – three of Scotland’s flagship links courses which help attract almost 220,000 annual golf visitors to the country, according to Visit Scotland.

In August, Muirfield staged the Women's Open for first time after hosting 16 editions of the men's tournament.

“Scottish golf tourism is thriving, and Scotland is a bucket list destination for most golfers around the World,” added Dermot Synnott, Director of Global Partnership for the World Golf Awards.

“It offers a vast range of parkland and links options across all its regions, so the travelling golfer really is spoilt for choice.”

Shinnecock Hills Golf Club on Long Island, New York, was crowned the World’s Best Golf Course, continuing a strong American run after back-to-back wins for Augusta National.

Meanwhile, JA The Resort Golf Course in Dubai won Best Nine Hole Golf Course and Costa Navarino in Greece was recognized as the World’s Best Emerging Golf Destination.
