Trial gives new hope for patients with asbestos-linked cancer
James Fox, from Dorset, was diagnosed with mesothelioma in 2018 and given less than a year to live.Having tried other treatment options, he was offered the chance to join the new drug trial, and said the results had been remarkable.As an architect, in the 70's and 80's he was exposed to asbestos, which has now been linked to his aggressive cancer, with only 5% of those diagnosed surviving for five years or more.Mr Fox said: "I've had seven really good years and been able to enjoy life almost to the full so that's wonderful. "So far it's been almost a miracle in my case."
The trial was run by researchers at the University of Leicester and the Cancer Research UK Southampton Clinical Trials Unit, with funding provided by the charity Asthma + Lung UK.Called the NERO trial, it looked at a class of drug known as PARP inhibitors, which work by blocking the repair of damaged DNA in cancer cells, thereby causing the cancer cells to die.PARP inhibitors have already been shown to improve the survival of patients with some types of breast and ovarian cancers. A previous study had also shown that mesothelioma does respond to this type of drug, but more evidence was needed as to whether it could improve outcomes for patients.At 11 hospitals across the UK, 88 patients whose mesothelioma treatment had stopped working took part in the trial.
'Enormous hope'
Those given a PARP inhibitor called niraparib were found to have a 27% reduction in the risk of the cancer progressing or death. This delayed the worsening of mesothelioma by an average of 1.5 months compared to those receiving the standard of care treatments, with a number of patients seeing a much longer period of time where their cancer was being controlled.Prof Griffiths said: "We have shown for the first time that this kind of drug can improve progression-free survival for mesothelioma patients compared with their usual treatment in the NHS. "This gives enormous hope to those patients and their families and means we can now carry out further research to find out more about how these treatments could be tailored and enhanced to stimulate an even better response in more people."
For Mr Fox, who has five grand children, the treatment has surpassed all his expectations."It's dramatic, the improvement, I don't think this could have possibly happened without this particular drug, without being offered it. "It must be the drug that's been keeping me fit and alive, so I'm very grateful for that."

Rare 100% Rotten Tomatoes sci-fi show is now available to stream
Sliders was a 90s sci-fi show that was given a new lease of life after it was cancelled by Fox, and its star Jerry O'Connell has opened up on its revival Sci-fi buffs and fans of shows akin to The Big Bang Theory are in for a treat, as a beloved 90s classic is now available to stream absolutely gratis. The series Sliders, which explores the adventures of a group traversing various parallel universes via a wormhole, was conceived by Robert K. Weiss and Tracy Tormé. Initially broadcast on Fox for its first three instalments, Sliders was then shifted to the Sci-Fi Channel where it concluded with two additional seasons. Although it was initially cut by Fox, the show wrapped up in February 2000 and has since been lauded by critics far and wide. Sliders boasts a formidable 100% rating on Rotten Tomatoes, with reviewers praising its enduring appeal season after season, reports the Express. Flick Filosopher endorsed the show, stating: "This is compulsively watchable popcorn TV, fluffy and fun, more compelling in the aggregate than each individual episode might be, with little clues sprinkled here and there that contribute to a larger intrigue." Additionally, the Chicago Tribune complimented the series: "It looks good, a smart, imaginative, often humorous exploration of what it would be like to be trapped traveling from one version of Earth to another, trying to get home." Jerry O'Connell, who starred as Quinn Mallory, discussed the series' pivot in narrative and style and its eventual resurgence post-cancellation during an interview with Yahoo Entertainment. He remarked: "I do think that Sci-Fi at that time was looking for darker science fiction fare with an emphasis on heavy special effects makeup. "The people who invited us to the party left the party, and that was disorienting. Some of our cast members felt abandoned. "Some pretty great people like Marc Zicree, Richard Compton, and David Peckinpah did come on to the show, but everything had just changed directions." He was only 25 when he wrapped up the show and, after being given the chance to direct a few episodes, he tried to recapture its original allure. The star added: "If you notice, in the episodes I direct, I did manage to get us back to sort of that thought-provoking, parallel-universe fun that made the show popular to begin with." Sliders is now available for free viewing on Pluto TV's Sci-fi Series channel.

You're washing your bedding wrong! Microbiologist reveals how often you should really clean your sheets - and the item you should refresh every three days
With our hectic daily lifestyles, cleaning the bed linen is surely one of the household chores that gets put off the most. And with the mammoth effort involved in putting on a double duvet cover, it's little surprise some of us go for months before getting around to it. But if you rarely change your bedding, you may want to start making it one of your regular jobs, according to a microbiologist. Dr Primrose Freestone, professor of clinical microbiology at the University of Leicester, says we should wash our sheets and pillowcases one a week at least. However, for those who sweat heavily, have been ill, or share their bed with pets, the sheets should be washed even more often. Washing linen removes body sweat, oils, microbes, allergens and dead skin cells, which can lead to infections and allergic reactions - not to mention other unsavoury stains. 'While we often focus on how many hours we're getting, the quality of our sleep environment matters too,' said Professor Freestone. 'Regular laundering removes the biological soup of sweat, skin, dust and microbes, which helps to reduce allergic reactions, prevent infections and keep odours at bay.' Each night, we shed thousands of skin cells, excrete oils from our sebaceous glands, and sweat up to half a pint of fluid – even if we've showered just before bed. Skin sweat and oils can support the growth of microorganisms, too small to be seen by the naked eye, Professor Freestone explains in a new piece for The Conversation. Our skin hosts millions of these microbes such as bacteria and fungi, many of which are transferred onto sheets, pillows and duvets as we move during the night. Unfortunately, a gradual build-up of bacteria on your sheets can increase the likelihood of acne, eczema, itching and asthma. Fresh sweat emitted from our skin may be odourless, but bacteria on our skin break it down into smelly byproducts – which is why we get BO. So we should be washing sheets and pillowcases once per week at 140°F/60°C or higher with detergent to kill the bacteria, the academic said. Meanwhile, some fungus species, such as aspergillus fumigatus, have been detected in used bed pillows and can cause serious lung infections, particularly in people with weakened immune systems. Another fungal species called Candida albicans – which can cause oral thrush, urinary tract infections and genital yeast infections – can survive on fabrics for up to a month. What's more, flakes of skin we shed every night become food for dust mites – microscopic, insect-like creatures that thrive in warm, damp bedding and mattresses. The mites themselves aren't dangerous, but their faecal droppings are potent allergens that can aggravate eczema, asthma and allergic rhinitis, also known as hay fever. Also, during the day, our hair and bodies collect dust and pollen, which can also transfer to our bedding – triggering allergies and affecting breathing. However, if you sleep with a pet, you should launder your bed sheets and pillowcases even more often – every three to four days, according to the expert. 'Animals introduce extra hair, dander, dirt and sometimes faecal traces into your sheets and blankets, increasing the frequency at which you should be washing them,' she said. According to Professor Freestone, it's not just sheets and pillowcases that should be cleaned more often. Mattresses should be stripped and vacuumed weekly, duvets should be laundered every three to four months, and pillows themselves should be washed and dried every four to six months. Pillows should also be frozen in a suitable freezer for at least eight hours to kill the dust mites lurking inside them. According to research, some Brits go months without washing their bedding, even though freshly-laundered sheets have been linked with a better night's sleep. A 2022 YouGov poll found that just 28 per cent of Brits wash their bed sheets once a week, while 4 per cent wait for two months or more. Potential factors for delaying the job include laziness, lack of time, finding it physically difficult and prioritizing use of the washing machine to clean clothes instead. According to Professor Freestone, regular washing is 'more than just a question of cleanliness' as a good night's sleep is 'essential for normal brain function and overall health'. 'A clean, welcoming bed with crisp sheets, soft pillowcases and fresh blankets not only feels good, it also supports better rest,' she added. 'A hygienic sleep environment is a small but powerful investment in your wellbeing.' Why you should never charge your phone under your pillow during a heatwave Whether it's to send a 'Goodnight' message, play relaxing music, or set an alarm for the morning, many of us like to keep our phones near our bed at night. But while this can be useful, there's one dangerous habit that people should stop immediately, experts say. Apple has issued a warning about charging your iPhone under your pillow, as it can easily overheat and become a potential fire hazard. And it adds to previous concerns that dirt and dust in the charging port of phones can also pose a fire risk. 'Use common sense to avoid situations where your skin is in contact with a device, its power adapter, or a wireless charger when it's operating or connected to a power source for long periods of time,' Apple's website reads. 'For example, don't sleep on a device, power adapter, or wireless charger, or place them under a blanket, pillow, or your body, when it's connected to a power source. 'Keep your iPhone, the power adapter, and any wireless charger in a well-ventilated area when in use or charging.'

‘Alarming' inequalities in death rates for children in intensive care
There are also higher death rates among children of Asian ethnicity on these wards compared to white children, researchers said. Experts called for urgent action from policymakers and health leaders in light of the findings, which they described as 'deeply troubling'. For the study, researchers from Imperial College London, University of Leicester, UCL and University of Leeds analysed admissions of children to UK paediatric intensive care units (PICUs) between January 2008 and December 2021. Some 245,099 admissions for 163,163 children were included. Researchers found death rates were 4.2% among the most deprived children at 2,432 deaths per 58,110 admissions, compared to 3.1% among wealthy children with 1,025 deaths per 33,331 admissions. According to the study, youngsters living in the poorest areas had 13% higher odds of dying compared to those living in the least deprived areas. Researchers also found 5.1% of Asian children admitted to PICU died – 1,336 deaths per 26,022 admissions – compared to 3.2% of white children, with 4,960 deaths per 154,041 admissions. Children of Asian ethnicity had 52% higher odds of death among Asian children compared to white children, the study suggests. Dr Hannah Mitchell, of the department of surgery and cancer at Imperial College London, said: 'Paediatric intensive care offers the highest level of support for the sickest children. 'Our findings show that inequalities persist even at this stage of care and are deeply troubling. 'These are not just statistics – they represent real, preventable differences in outcomes for critically ill children.' Elsewhere, the study found both deprived children and those of Asian ethnicity were more likely to be severely unwell when admitted to PICU compared to wealthier and white children. Youngsters from ethnic minority backgrounds also had longer stays in PICU – 66 hours on average – while white children averaged at 52 hours. Dr Mitchell added: 'Our findings are especially alarming in the context of rising levels of child poverty in the UK, where 4.5 million children are now growing up in poverty (31% of all children), 800,000 more children compared to 2013 (27% of all children). 'These findings should prompt urgent action from policymakers and healthcare leaders.' Dr Mitchell said the study, published in The Lancet Child and Adolescent Health, 'adds clear, national-scale evidence of disparities in intensive care. 'Reducing avoidable deaths in children must include serious, sustained action to reduce child poverty, improve access to healthcare, and address the structural barriers faced by marginalised communities,' she added. Reacting to the study, Professor Habib Naqvi, chief executive of the NHS Race and Health Observatory, said: 'These sobering findings are shocking and unacceptable. 'Your ethnicity, background or where you live should not determine your chances of survival. 'We need immediate and collective action to address the issues outlined in this study, and in many other studies that show the impact structural inequalities and bias have on healthcare access, experience, and outcomes. 'Not tackling these issues is leading to avoidable harm to countless patients, families, and communities.'
