Technique that examines fragments of foetal DNA in mother’s bloodstream could limit need for invasive screening, according to researchers

A new maternal blood test that can detect thousands of serious genetic conditions in the developing foetus could limit the need for invasive screening during pregnancy, according to scientists.

The test, to be described at the European Society for Human Genetics conference in Gothenburg on Saturday, relies on detecting tiny fragments of a foetus’s DNA that circulate in the mother’s bloodstream during pregnancy. Using advanced sequencing techniques, scientists were able to identify a very high proportion of genetic conditions, such as cystic fibrosis, that are currently only reliably diagnosed using amniocentesis or other invasive tests.

Journalist and healthcare campaigner was driving force behind patient safety initiative after death of 13-year-old daughter

The healthcare campaigner and journalist Merope Mills has been made a CBE in the king’s birthday honours list for services to patient safety.

Mills, a senior editor at the Guardian, was a driving force behind the introduction of an initiative in England said to have potentially saved hundreds of lives. She has spent years campaigning for the introduction of Martha’s rule under which patients, relatives and staff can seek a second opinion if they have concerns about the care being provided.

Is my metabolism slowing with age? What’s the secret to good skin? And is there anything I can do about my crows feet? Medical, health and diet experts offer a midlife MOT

According to the dietician Rick Miller: “By the time a man hits his mid-40s, several physiological changes are already under way. Testosterone drops at around 1-2% annually from the mid-30s, insulin sensitivity decreases and the liver’s capacity to process certain nutrients changes. The diet that kept a man lean and energetic in his 30s simply stops working.”

The confusion over hantavirus and Ebola is a reminder that we must do better at explaining how to respond to an outbreak

Two unfolding outbreaks continue to command global attention. As a hantavirus outbreak tied to a cruise ship appears to be petering out, Ebola cases continue to mount in Africa. Alongside them have emerged familiar artifacts of the Covid era, including dashboards, trackers, maps, risk estimates and a polarized mix of alarming and dismissive takes.

Once again, we’re able to watch disease spread in almost real time. Yet despite all the information, many people are left asking the same questions: what can I trust? How bad is this, really? What should I do?

Desperate US parents paying up to $20,000 a session for a procedure scientists say could be bogus

Autistic children as young as 18 months old are being injected with human stem cells derived from umbilical cords in unapproved, unproven and potentially harmful “treatments” that scientists warn are proliferating across the US under the active encouragement of the US health secretary, Robert F Kennedy Jr.

Clinics in Florida, Texas and other states are selling what they bill as “regenerative medicine” to families with autistic children who have intensive care needs. Parents who have taken their children through the process talked about their hopes and fears for a therapy that appears to be gaining ground in the US.

Feeling abandoned and overwhelmed, families are turning to controversial new therapies backed by the US health secretary

Landyn Holdren is an eight-year-old autistic child who has high support needs and is nonspeaking. His mother, Christy Holdren, says he can be self-harming, slapping his chest, face or head when distressed.

Later this month, she will spend $15,000 on an unapproved stem cell treatment she hopes might help him.

My friend Joseph Ana, who has died aged 73, spent the best part of two decades in the UK working for the NHS as a urologist and then as a GP. But his heart was always in his native Nigeria, to where he returned to become a health commissioner. He used the knowledge and experience he had gained in the UK to help rebuild faith in the local healthcare system, overseeing, among other things, improvements in vaccination rates and the introduction of a state-wide ambulance service.

Joseph was born in Zaria in Nigeria, to Onun Onebieni Uguana Ana, who worked on the railways, and Ubu Ana, his first wife. The family compound was in Ikot-Ana in Cross River state, and his family were kingmakers, choosing a king from among the two royal families.

UN agency head warns of ‘major threat’ as global testing and treatment falls

A funding crisis and increasing repression of human rights are making the resurgence of an HIV epidemic more likely, the international agency tackling Aids has warned.

Winnie Byanyima, head of UNAids, said: “It’s the biggest disruption since the global HIV response was put together and it poses a major threat to the progress we have had.”

I think I’ll leave new methods to measure biological age to the Kardashians. Too much knowledge about your mortality can be bad for your health

In the season 5 finale of The Kardashians, the family took a commercially available blood test to discover how fast their bodies were ageing. It came as little surprise, given their privileged lifestyles, that the reality TV stars were said to be ageing more slowly than most mortals of the same age. Khloé, then 39, found she had a biological age of 28. Cue whoops of joy and much smugness.

The Kardashians join a growing list of celebrities who have taken similar tests and then crowed about their “biological ages”. Now, there’s a new test on the block.

Imperial College scientists analysed health records before and after introduction of air pollution reduction zones

Low emission and clean air zones attract controversy whenever they are proposed, but there is growing evidence that they work in improving air quality. The Bradford zone was followed by a reduction of about 25% in GP visits for heart and breathing problems and survey data shows that the central London zone was followed by a reduction in the likelihood of a person taking sick leave.

Now analysis of health records has found emergency admissions to hospital reduced after the introduction of the T-charge and ultra-low emissions zone (Ulez) in central London.

Doctors say therapy that genetically modifies person’s T-cells could offer cure for chronic autoimmune disease

Five lupus patients in England are in remission after being treated with a revolutionary therapy that genetically modifies their own cells, in a medical breakthrough that could offer people a cure, doctors have said.

CAR (chimeric antigen receptor) T-cell therapy involves removing a type of white blood cell also called T lymphocytes, which are crucial for hunting out infected or damaged cells, and engineering them to spot and destroy disease. The T-cells are then fed back into the patient via an infusion to reset their immune system.

One-off programme to begin in July after recent MenB outbreaks in Kent, Dorset and Berkshire killed three people

Teenagers in their final school year and young people starting university will be offered two doses of a vaccine to protect them against meningitis B, the government has announced.

The one-off vaccination programme, which will begin in late July, comes after an unprecedented outbreak of meningitis B in Kent earlier this year along with clusters of cases in Dorset and Berkshire that, together, led to the deaths of three young people.

New Farm Bill places caps on non-US foods; nutritionists say it restricts availability of healthy meals for kids

School nutrition workers and advocates have “lots of concerns about bananas”, said Erin Ogden, policy associate for federal child nutrition programs at the Center for Science in the Public Interest (CSPI).

Bananas are nutrient-dense foods that many children like. That makes them popular offerings in school cafeterias, since any healthy food that a kid will eat prevents waste and ensures that child isn’t eating either nothing or something less wholesome instead.

Regulator approval means patients who meet criteria will be able to purchase tablets with private prescription

Patients in the UK will soon be able to buy the Wegovy weight-loss pill, the medicines regulator announced on Thursday.

It is the first GLP-1 receptor agonist tablet for weight-loss to be approved by the Medicines and Healthcare products Regulatory Agency (MHRA), making the UK the third country to authorise the pills, behind the US and the United Arab Emirates.

When I started nursing at 21 we were able to deliver timely, good care. That has become nearly impossible

• Sophie (not her real name) is a member of the Royal College of Nursing and a senior A&E nurse in a hospital in the south of England

I began my career as an A&E nurse in 2010, when I was 21. It was a completely different world. If a patient needed immediate attention, there was easily the capacity for two nurses to look after them straight away. The NHS target of seeing patients within a four-hour window wasn’t something we gave much thought to, as it was pretty much a given that a patient would be admitted, transferred or discharged within that time. I don’t ever recall seeing a patient and feeling awful about how long they had waited.

It’s amazing to think how common it used to be for emergency departments to be almost empty at times in the evenings. As well as being much needed respite from the demands of the job, it was also a valuable time to learn from more senior colleagues. Nurses with decades of experience would take new recruits under their wings and help us practise our skills. That time is when I learned to plaster limbs and dress wounds. I wish I could do the same for my junior colleagues now. We used to be able to give timely, good care – now it has become near impossible.

Data published for the first time recorded 2,241 daily cases of A&E corridor care, with 699 patients also treated in other inappropriate settings

Almost 3,000 patients a day in England are receiving care in hospital corridors due to an unavailability of beds in A&E units across the country, according to official figures.

Corridor care occurs when a patient receives treatment in a setting that is clinically inappropriate and is deemed to be undignified and unsafe.

London, the east of England and the West Midlands have highest number of cases, as UKHSA urges families to get children vaccinated

Two children in England have died from measles, health officials say, as data shows more than 100 new reported cases in the last fortnight.

The UK Health Security Agency (UKHSA) said on Thursday that two children had died this year, one from “acute measles” and the other from the “late effects of measles”.

There’s a downside to too much convenience: it harms our bodies

There is a seductive fantasy being floated by AI executives that all the efficiency their products will bring us will lead to humans finally returning to their essential, best selves. Picture it: when this day arrives, we’ll spring from our chairs, push aside our keyboards and, supposedly, do all things we’ve been meaning to do: hike, cook and finally take a pilates class.

It’s true – AI has already taken some workday drudgery, such as reading and writing contracts, presentations and quarterly reports, off some people’s plates. Within a few years, we’re told, a team of invisible digital assistants will take over mundane domestic chores too: making medical appointments, renewing our car insurance and planning. The vision is enticing: finally, the moment when we can stop switching-switching-switching between screens and devices, put our health first and flourish. Unfortunately, if the history of innovation teaches us anything, it’s that labor-saving technology has rarely, if ever, triggered healthier habits.

Drive-throughs and microwaves did not lead to more time spent walking in nature. When escalators replaced stairs, email took over from walking over to talk to a colleague, and wandering through the video store was swapped out for streaming from the couch, few of us considered how these tiny conveniences would chip away at our physical health, year after more efficient year. A task that took almost no effort used to be described with the saying: “You hardly need to lift a finger.” Now, we literally lift a finger and – tap – the chore is done.

Exclusive: Transport secretary, Heidi Alexander, says cycling and walking plan focuses on ‘everyday travel needs’

• UK politics live – latest updates

Ministers are to launch a major push to get more children walking and cycling to school as part of a wider boost for “active travel” by the transport secretary Heidi Alexander.

In the first significant change to active travel policy since the Boris Johnson era, thousands of new safe routes and crossings will be built around schools in England, with a target of having at least 60% of all children walk, cycle or wheel to school by 2035.

NHS bosses urge all hospitals in England to use ‘digital triage’ process to combat overcrowding in emergency services

Patients who turn up at A&E with non-urgent ailments could be told to come back another time under NHS plans to stop hospitals becoming overcrowded and avoid the service’s usual winter crisis.

Eighteen hospitals in England are already using “digital triage assessment” to help A&E staff decide which patients need to be seen right away or be dealt with in another way. If patients do need urgent care they are treated at once in the usual way. But if they have more minor ailments and can wait, they are told to come back later that day or the next day, or are referred to a community-based service, such as a GP or pharmacy.
