Global NHS osteoarthritis study could lead to new treatments
Led by Helmholtz Munich, the largest scientific research organisation in Germany, genetic codes and DNA of almost half a million osteoarthritis sufferers globally - including 1,000 volunteers from Sheffield - were compared with that of 1.5 million people without the disease, the trust said.The team identified 962 genetic variations more commonly found in those with osteoarthritis; more than 500 of which had not previously been identified, it said.The number osteoarthritis sufferers was predicted to rise to a billion people by 2050 and despite the impact "no disease-modifying treatments are currently available", researchers said.However the new work "paves the way for potential new drug treatments and personalised therapies," they continued.
'Repurpose existing treatments'
Prof Mark Wilkinson, Honorary Consultant Orthopaedic Surgeon at the trust and the University of Sheffield, said the findings were "hugely important" and would "open up exciting new avenues" for millions."As well as identifying potential drug targets and opportunities for us to repurpose existing treatments that already target these genes in other conditions, this research has also significantly advanced our understanding of the underlying biological mechanisms associated with the disease," Prof Wilkinson said.Eight biological processes which regulate the body's internal systems and cell function were found, "shedding light on the disease's biological mechanisms", the trust said.Some of these genes contain proteins already targeted by drugs approved for other conditions, which could accelerate treatment development, it added.

Helm by Sarah Hall review – a mighty epic of climate change in slow motion
Even if Sarah Hall did not begin her acknowledgments by saying that it's taken her 20 years to write Helm it would be evident. Not from a cursory glance at her bibliography, perhaps: in that time Hall has published six other novels and three volumes of extraordinary short stories. But in every other way, and the moment you begin reading. There's the subject, for starters. Ever since the first paragraph of her first novel, Haweswater, in which an early 20th-century man drives his horse and cart through the waters of a Cumbrian valley recently drowned by a dam, Hall has been concerned with landscape, with weather, with nature in all its forms, with the ways in which we affect each other. In The Carhullan Army, climate change has already happened. Cumbria is semi-tropical, temperate England a folk memory; a dystopian vision that feels, this baked summer, uncomfortably close to reality. The Wolf Border, published in 2015, was, among many other things, about the ethics and unpredictabilities of rewilding an apex predator, while Hall's last novel, Burntcoat, written in the first lockdown, was set in and after a pandemic. Her story Later, His Ghost is set in a perpetual windstorm of total climate breakdown; in One in Four, a virologist writes to his wife, apologising for getting things wrong. In this new novel, weather and climate are not just potent settings but the main event. The central character in Helm is the Helm, Britain's only named wind. This wind, which is local to Cumbria, occurs when air sweeping down Cross Fell, above the Eden valley, creates both a crest and a low bar of cloud. 'Tricky to explain/visualise', admits Helm. 'For now, imagine a skater launching off a quarter pipe two thousand feet high, then somersaulting. Again. And again and again.' As the book begins, Helm witnesses its own arrival. An ice age, sun flares, ash cloud; and, relatively insignificant in the context of such deep time, the evolution of humanity. Because there are many people in the novel, too, which is structured by braiding their stories with Helm's, but also with lists: the forces of Helm, for instance, which range from '0. Zero Helm (complete calm). Mean wind speed < 1mph. Weathervanes and trees unmoving, grass still, water as mirror, smoke rising vertically from roundhouses/cottages/plague pyres' to '12. Hurricane Helm (Hand of God). Wind speed 73-83mph, phenomenal damage and widescale loss of life, Eden reconfigured biblically, Carlisle-Settle train lifted off the tracks, history made, FIN.' Other lists include names for Helm and the damage Helm can wreak; or the trinkets Helm collects, often after that damage (Howdah pistol, iron skullcap, Apple iPhone 11 64GB, Tornado F3 series, eject pin). The pictures humans make, trying to understand, locate, corral Helm. Helm finds people amusing, and watches as they succeed each other; Hall's ambition may be bounded by one valley, but it reaches through thousands of years. Her subjects range from a neolithic tribe to a medieval exorcist; from an isolated 18th-century wife to a quixotic Victorian meteorologist; from a wind-touched, lonely mid-20th-century child to a present-day academic counting plastic particles in the air. From stone tools to the Industrial Revolution to the advent of AI, each era has its own existential encounters with Helm: as deity or devil, as a psychological or a scientific mystery. Both sides are made complacent by Helm's longevity, size and power, by human smallness and briefness, neither realising, until perhaps too late, that these little beings threaten Helm's own existence. A project of this scope, which requires a range of research and imagination that could have produced several historical novels, not to mention an entire other volume of meteorological expertise, holds so much in suspension around its whirling, windy core that it could easily blow apart. But, despite the occasional threat or lull, Helm doesn't. Partly, I would argue, this is because of Hall's development as a consummate short story writer. Her novels are never less than hugely accomplished, but the narrative demands of the longer form, especially in more conventional earlier work, can sometimes dissipate the blaze of which she is capable. Hall is freed by the constraints of the short story – like the female sculptor in her last novel, Burntcoat, she burns away everything extraneous – and her work only gains in concentrated, suggestive power. Each strand of Helm has this concentration; the characters and voices could stand alone, but they flow together into something deep and rich, held together by the Eden valley, and its Helm. And by the writing. Hall's work on place, and especially this corner of England, has always been virtuosic, a tough and supple poetry anchored in decades of attention to Cumbrian land and plants and skies. In her first novels it sometimes threatened to submerge everything else, but in Helm is so embedded on the page that it's easy to take for granted, until you pause and back up to really look at the 'dirty, clay-slipped sky', or a gaggle of Victorian children, born into the shantytown that grows up around the railway, collecting on a hillside to eat magic mushrooms and stare at the 'silly jinking stars'. Every era in Helm has its own seeing; the same land, the same wind filtered through time-specific fears and hopes and work, time-specific knowings, from a neolithic world interpreted through animal behaviour to the bathos of 21st-century cycling waterproofs, pub menus, emails. Hall has a thrilling command of vocabulary, with the concurrent deployment of etymologies and the hinterlands they bring; words often work not as single notes, but as chords, big ideas slipping in on the wakes of concrete specificities. So NaNay, a neolithic girl, watches as the wind approaches: 'In the centre it was blue-grey, like bull-hide, with the dull pearl-shine of scales at its edges. It was faceless and its body was its only government.' The 'spectral gap' is a technical term of modern mathematics and quantum mechanics as well as meteorology. But what heft and metaphorical possibility such a gap has, when a retired policeman in a glider is required to fly into it. Above all it is the wind itself that holds this vastly ambitious, serious – but also often playful and ironic – book together. Some might find Helm's voice initially a little arch, a little unplaced relative to the human voices, but it grows on you. Antic, needy, angry, curious, millennia-old Helm, who gives and takes, fascinates and awes, is feared and loved, and loves in return; who absorbs violences, propitiations, yearnings, and who is now beginning to feel 'a bit wrong'. There has been so much change, over so many millennia, but this is different. 'It's complicated. Hard to put Helm's fingers on it.' It isn't that Helm is old, more that 'Whatever is wrong … feels insidious, sneaky, infectious. The surprise disease on the routine tests. Some kind of weird intimate growth you find accidentally and go, Jesus, how long has that been there? A toxic waft when you're asleep. Lights out.'

In the mid-20th century Helm searches for a young girl, his friend, who has been locked in an asylum, and, trying to look beyond the valley, 'rises, higher, until being is difficult'. At the 21st-century meteorological observation post, 2,000ft up, Helm whips and churns and 'calls to awful prayer'. A prayer for itself, perhaps, because whatever Hall's intentions – an urgent rallying, a tribute, a warning – this novel reads like nothing so much as an elegy.

Dog owner urges caution after pet bitten by adder near Whitby
A dog owner has urged others to be vigilant when walking their pets after her Labrador was bitten by a Mawer was walking three-year-old Malcolm on moorland above the North Yorkshire village of Egton, near Whitby, when he was bitten on 5 Mawer said her dog became dazed and its face began to swell up after the incident so she rushed him to a nearby vets for treatment."What scares me is that if I hadn't have seen the snake and what happened I wouldn't have known he had been bitten," the 55-year-old added. Mrs Mawer, from Egton, said she had stopped to take a photo of the adder - the UK's only venomous snake - moments before Malcolm was bitten."It only looked like it was the tail end of the snake that moved, so I wasn't 100% sure. "Malcolm didn't yelp, he didn't bark."When the pair got back to the car, Mrs Mawer noticed Malcom retching."After the 10-minute drive home he was really dazed, just stood there."When we offered him something to eat he just didn't take it, at which point we knew something was wrong. By the time we got to the vets his face was swelling up." 'It can be lethal' Dr Simon Beck, from the Beck Vetinary Practice where Malcolm was treated, said the practice saw adder bites about once a fortnight during summer months."It can be lethal if you don't get them treated quickly," he said."If a dog is bitten you need to get it straight back to your car and get it to a vet."If dog owners want to be low risk then they are better to take the dogs out in areas where there isn't moorland or heather." Mrs Mawer said Malcolm had made a full recovery since the incident, but said the experience had taught her two things."Don't stop to take a photo and if you see your dogs behaviour change after you have been on the moors, or if they are just acting unusually, seriously think about whether they have been bitten by an adder," she said.

The simple food swaps that can double your weight loss
'If two diets are nutritionally equal, according to nutritional guidance, does the level of processing still affect weight and health?' It's the question Dr Sam Dicken, a research fellow in the department of behavioural science and health at University College London (UCL), set out to answer in a landmark study published in Nature. The results showed that people who ate a diet of minimally processed foods (MPFs) lost twice the weight as those eating ultra-processed foods (UPFs) – even when both diets met Government healthy-eating guidelines. In the UK, more than half our calories come from UPFs such as ready meals, breakfast cereals and mass-produced bread. These everyday foods have been linked to more than 30 chronic diseases, including obesity, type 2 diabetes and stroke. Until now, most research has centred on nutritionally poor UPFs – high in sugar, salt and saturated fat, while low in fibre. This is the first study to focus on 'healthy' UPFs that meet nutritional recommendations for fat, saturated fat, protein, carbohydrate, salt, fibre, fruit and vegetables. 'Not all UPFs are inherently unhealthy,' says Dr Dicken, the lead author of the study. 'Supermarkets now offer plenty of healthier, nutritionally balanced UPFs, like wholegrain breakfast cereals and high-fibre ready meals.' Rob Hobson, a nutritionist and the author of Unprocess Your Family Life, says the study adds to concerns about the role of UPFs in weight gain and wider health. 'It's not just about additives, calories or sugar, but how food is made and how that affects our eating behaviour,' he explains. 'Relying less on UPFs – even ones marketed as 'healthy' – can support better weight management and long-term health.' While cutting out all UPFs is unrealistic in our current food environment, making a few, smart food swaps can make all the difference, say the scientists. Here's how to do it. Swap breakfast cereal with milk for overnight oats with frozen or fresh fruit Most breakfast cereals are ultra-processed, even those labelled 'wholegrain'. While often fortified with vitamins and minerals, they are typically sweetened and low in fibre – leaving you hungry again by mid-morning. 'Switching from a sugary, ready-made cereal to homemade oats with milk and fruit reduces calorie and sugar intake while boosting fibre, protein, antioxidants, vitamins and calcium,' says Dr Adrian Brown, the study's co-author and a senior research fellow in nutrition and dietetics at UCL. ' Oats provide slow-release energy, helping control blood-glucose levels, which may keep you feeling fuller for longer. Overall, they're a better option.' A review in Current Nutrition Reports found eating oats can support weight management by reducing body fat and regulating appetite. Rob Hobson's quick-and-easy overnight oats recipe Mix 50g rolled oats with 100ml semi-skimmed milk and 100ml apple juice Add half a grated apple, 1 tbsp chia seeds, and a squeeze of lime juice. Leave overnight in the fridge Top with berries and a spoonful of natural yogurt Swap a meal-deal chicken sandwich for homemade chicken-salad flatbread Even healthy-sounding sandwich fillings, such as chicken, can be processed or loaded with saturated fat and calories, especially with added mayonnaise. ' Pre-packaged sandwiches, often made with ultra-processed bread, have a soft texture that may encourage faster eating and less awareness of fullness,' says Hobson. A study in Cell Metabolism found people on a UPF diet ate twice as fast and consumed 50 per cent more calories per minute – an extra 500 calories per day. 'A homemade flatbread with grilled chicken, salad and a yogurt-based dressing contains lean protein and fibre in a more structured meal, encouraging you to eat more slowly and feel more satisfied,' says Hobson. Rob Hobson's quick chicken flatbread recipe Fill a wholemeal flatbread with 80-100g grilled chicken breast, mixed salad leaves, sliced cucumber and tomato Add a spoonful of plain yogurt, lemon juice and fresh herbs, such as coriander or parsley Swap a spaghetti bolognese ready meal for a homemade equivalent 'A ready-made spaghetti bolognese will contain processed meat that may be higher in fat and saturated fat,' says Dr Brown. 'It will be more energy-dense, providing more calories per bite.' The soft texture doesn't require much chewing, so you will eat faster and potentially override your body's satiety signals, consuming more before you realise you are full. 'Switch to a homemade version, made with lean, 5 per cent mince, and you'll likely eat fewer calories and less saturated fat for the same portion size,' says Dr Brown. 'Improve the protein and fibre content by adding lentils, vegetables, herbs and spices, and serving with wholewheat pasta. This will help you feel fuller.' Swap low-fat fruit yogurt for low-fat natural yogurt with fruit Low-fat fruit yogurts are often highly processed, with added sugars or sweeteners, flavours and thickeners. 'The label may show moderate calories, but the texture and sweetness can make them less filling and more rewarding to the brain, encouraging you to eat more,' says Hobson. 'A natural yogurt with whole fruit or a little honey is less processed, has more texture, and provides protein and natural fats that keep you fuller for longer. You can also control the sugar content.' If you're trying to lose weight, Dr Brown advises checking labels. 'Some natural yogurts are higher in fat – look for a reduced-fat option,' he says. Swap processed nut snacks for whole nuts 'Processed nut snacks [such as a fruit-and-nut bar], especially flavoured ones, are often UPFs even if they include nutritious ingredients,' says Hobson. 'Their engineered textures and sweet-salty profiles can drive reward-driven eating.' That's why it's so hard to stop at one handful. Whole nuts with dried fruit provide more fibre, slowing down eating speed and energy release. 'This reduces calorie intake and help control appetite,' says Hobson. A Harvard study found people who ate whole nuts were less likely to gain weight gain. If processed fruit and nut bars are your go-to, Dr Brown recommends the following: 'Swap for a small, 25g handful of unsalted nuts, such as almonds or walnuts, plus a piece of fruit,' he says. 'You'll get less salt, more vitamins, minerals, antioxidants and fibre – and the fruit counts towards your five a day.' What we can learn from the UPF v MPF trial In the trial, 55 overweight adults were given either: a UPF diet of convenience foods, such as cottage pie ready meals, fortified cereals and pre-packaged sandwiches an MPF diet of homemade meals, such as cottage pie, overnight oats with berries, and chicken salad with flatbread Both diets met the UK's Eatwell Guide, which outlines the main food groups and their recommended proportions for a healthy, balanced diet. Meals were delivered for eight weeks, with no calorie counting or portion control. After a four-week break, participants switched diets, for another eight weeks. Both groups lost weight, but people eating MPF meals lost twice as much (2 per cent of body weight, versus 1 per cent on the UPF diet). 'Continued over a year, the MPF diet could mean a 9 to 13 per cent weight loss, compared with 4 to 5 per cent on the UPF diet,' says Dr Dicken. 'That's significant.' The MPF diet also led to greater fat loss, especially visceral fat, which raises the risk of metabolic disease. Neither diet caused muscle loss – likely because the diets were nutritionally balanced. 'The main message is that nutritional guidelines work – both groups lost weight,' says Dr Dicken. 'However, processing still makes a difference. Choosing foods that are less processed may help you lose more weight.' UPFs are engineered to be moreish. 'They can often be energy-dense, with more calories per bite, and softer in texture,' says Dr Dicken. 'This makes them easier to eat quickly, so you consume more before your brain realises you're full.' By contrast, MPFs are bulkier, higher in fibre and take longer to eat, so they are more filling. In the trial, MPF participants consumed about 290 fewer calories a day, compared with 120 fewer on the UPF diet. They also found it twice as easy to resist cravings. Healthy weight loss tips from the experts Dr Sam Dickens says: Follow the Eatwell Guide: more fruit, vegetables, wholegrains, pulses, nuts, lean proteins. Fewer than 0.1 per cent of Britons follow all the guidelines. Prioritise high-fibre foods. Check calorie density and be cautious with calorie-dense foods that have a soft texture, because they're easier to overeat. Using front-of-pack labelling as a guide, aim for foods with around 120-130 kcal per 100g. Dr Adrian Brown says: Speak to a GP or practice nurse. You may be eligible for structured support, such as the NHS Digital weight management programme or a local referral scheme. Avoid focusing solely on weight loss. Concentrate on improving your general health and small-scale victories, such as better sleep, improved energy, or being able to play with your grandchildren. Having other goals keeps you motivated and supports long-term success. If it feels overwhelming, reach out for support. Weight regulation is complex. No one should feel they're expected to do it alone.
