Scientists find "chink in armour" of aggressive childhood cancer

Scientists believe they may have found a way to treat a rare but devastating cancer that kills young children often within months of their diagnosis.

There is currently no treatment for malignant rhabdoid tumours, which usually develop in the kidneys and have no symptoms in the early stages. By the time they are diagnosed, the cancer has often spread to other organs and is fatal. Most of those affected are infants and toddlers.

The mutated gene that causes the cancer is well known, but scientists have not been able to find a way to target it. However, scientists working for the Institute for Cancer Research (ICR) believe they have a made a breakthrough. They have now identified two other genes that appear to be implicated in driving the growth of the tumour, which produce proteins that can be inhibited by drugs that are already in use in other cancers or are in the development pipeline.

Prof Paul Huang, team leader of the protein networks laboratory at the ICR, says they have found “a chink in the armour” of these very aggressive tumours, using drugs that attack proteins known as kinase inhibitors.

“There are a lot of kinase drugs out there, so we don’t have to re-invent the wheel,” he said. “In many cases in drug discovery you find a new target and spend 10 to 20 years developing drugs against it.”

In this case, they hope that will not be necessary . “We have been able to re-purpose existing drugs, some of which are already approved.”

So far, the drugs have been tested against cancer cells in the laboratory. The scientists, who have published their results in the journal Cell Reports, found that inhibiting proteins produced by one of the genes had little effect, but attacking both of them killed the cancer cells.

The drugs pazopanib, dasatinib and sunitinib were all successful at inhibiting the protein from the PDGFRA gene – but if high levels of protein from the other gene, called FGFR1, remained, the cancer returned and would not respond to treatment even at higher doses. This may explain why, when doctors have tried chemotherapy with their young patients, even where it has worked at first, resistance has quickly set in.

An existing drug called ponatinib, currently in use as treatment for leukaemia, can target both proteins at once. But there are questions over the safety of the drug in children, so there will be a need to screen other drugs to find one with fewer side effects that works.

The cancer is very rare – there is one case in 2 million children – but the work the ICR is doing will pay dividends in other cancers too. About 20% of all cancers have genes from this class.

Studies in mice will now be necessary before the drugs can be tried in children. The ICR is leading the world in the hunt for treatments for very rare children’s cancers, which are very unlikely to make a profit and are not a field that private drug companies are keen to enter.

Prof Paul Workman, chief executive of the ICR in London, said: “We need to see much better, more targeted treatments for children with cancer, that further drive up survival rates and spare children the serious long-term side-effects that conventional chemotherapy can cause.

“This study provides an exciting pointer for how we might treat more effectively an aggressive childhood cancer for which there is currently no cure. It’s crucial, when as here there is a strong scientific rationale for a new treatment approach in children, that we can assess them as rapidly as possible in clinical trials. At the moment, it’s much too easy for pharmaceutical companies to avoid evaluating their drugs in children, even when there is good evidence that they could benefit.”

Jennifer Kelly’s four year-old daughter Grace was diagnosed with malignant rhabdoid tumours two years ago and died soon afterwards. Her mother set up the Grace Kelly Ladybird Trust to fundraise research into childhood cancers.

“Grace went from being a happy, healthy schoolgirl to passing away within three weeks,” said her mother. “She started school in September and didn’t make it to half-term. She was an athlete – she was the monkey hanging upside down from the monkey bars. Even when she was admitted to hospital initially she seemed quite well. It progressed very rapidly.

“It is basically a diagnosis of death, whether they try to hold it at bay with chemotherapy for a while or not. They simply can’t treat them. There is a lack of funding for childhood cancers as a whole. People don’t realise childhood cancer is the biggest medical cause of death in children in the UK. People think it is rare and it actually isn’t. It is that that shocked us more than anything else.”

One in 500 children get some kind of cancer before the age of 14, according to figures from Cancer Research UK. In the UK, 1,700 children under 14 get a diagnosis each year, and 2,300 between the ages of 14 and 20.

Young people urged to get vaccinated against aggressive meningitis W

Students and other young people are being urged to get vaccinated against an aggressive strain of meningitis that killed 24 people in the last year for which there are figures.

Public Health England (PHE) said cases of meningitis W, which can cause life-changing disabilities and kills one in 10 who contract it, were on the rise. It is one of the most aggressive and dangerous forms of the disease. In 2009 there were 22 cases in England, but in the last year there have been more than 200.

Young people going to university are at particular risk because they mix with so many new people, some of whom may be carrying the meningococcal bacteria that cause meningitis W and septicaemia or blood poisoning.

PHE urged them to be immunised with a new vaccine, introduced last year, which protects against four strains of the bacterial infection – A, C, Y and W.

Between 2009 and 2012, there were just four deaths from meningitis W, but in 2013-14, the last year for which figures are available, the figure rose to 24. For the first time in a decade, babies and toddlers were among those who died. As other strains have become less of a problem, meningitis W now accounts for a quarter of all meningitis infections.

“Since 2009, there has been a rapid increase in cases of Men W across England, with students particularly at risk,” said Dr Mary Ramsay, the head of immunisation at PHE. “Protecting young people from this potentially deadly disease as they embark upon one of the most important periods of their lives is vitally important. The vaccination will save lives and prevent lifelong devastating disability.

“We are encouraging all eligible 17 and 18-year-olds who have just left school to get vaccinated, particularly those heading to college or university. Young people and those around them should be alert to the signs and symptoms of meningitis and septicaemia. Get vaccinated as soon as possible, remain vigilant and seek urgent medical help if you have concerns for yourself or friends.”

Meningococcal bacteria live in the back of the nose and throat in about one in 10 of the population without causing any illness. The bacteria is spread from person to person by close contact with a person carrying the bacteria, such as coughing, kissing and sneezing.

All meningococcal bacteria can cause meningitis and septicaemia, but meningitis W can also cause other illnesses such as pneumonia and joint infections. The early symptoms are headache, vomiting, muscle pain, fever and cold hands and feet.

GPs have been asked to call in young people up to the age of 25 for vaccination. Universities have also been asked to urge students who have not been vaccinated at home to get the jab locally.

Meningitis charities are also sounding the alarm. “Up to a quarter of students carry the bacteria that can cause meningitis compared to one in ten of the general population. In the UK every university could experience at least one case of meningitis amongst its students within the first term,” said Liz Brown, the chief executive of Meningitis Now.

“It’s vital that those going to Uni this autumn are not complacent about the threat of meningitis. We urge them to take up this lifesaving vaccine before they go.”

Vinny Smith, the chief executive of the Meningitis Research Foundation, said: “We’re encouraging students going to uni for the first time to do something great today. By getting this free meningitis vaccine from your GP you’re not only protecting yourself from a potentially deadly disease, but also protecting others by stopping the spread.

“It’s also vital to watch out for your friends if they’re unwell. If people do have meningitis it can be like a very bad hangover that quickly gets worse. It can be deadly, so act fast and get medical help.”

Mom died soon after delaying aggressive cancer remedy "to have a baby"

She had fought the illness for more than 4 many years, Manchester Coroner’s Court was advised.

Her death came despite undergoing stem cell transplant, and her family members think she would have survived if she had chemotherapy.

But they explained she would not have been in a position to turn into a mom, which she longed for.

At the inquest, Dr Jim Cavet, consultant haematologist at Christie Hospital, Manchester, stated Mrs Cockx deferred remedy in 2010 and in 2011, when she grew to become pregnant.

Dr Cavet met his patient to discuss her remedy program all through her pregnancy right up until she gave birth to Harriet by means of a C-area.

Tests showed that following the birth of her daughter, the cancer had returned, but much more aggressively than before.

Dr Cavet informed how the new mom place her daughter’s well being first during, in spite of being in “a rather undesirable way” right after the birth.

“Nicola was really concerned for Harriet and her health and was reluctant to have any chemotherapy even then,” mentioned Dr Cavet.

“She did accept steroids and they dealt with the higher ranges of calcium but not the underlying myeloma.”

Mrs Cockx first realised she had a issue in June 2008 when she began limping.

3 months later she went on a company trip in Germany with her father, John Flowers.

Although there she decided to see an orthapaedic professional about her leg, but tripped and fell on the way to the medical doctor, breaking her femur.

It was only then she was diagnosed with bone marrow cancer.

Her husband Rudy Cockx informed the inquest that when the diagnosis came, it was “extremely stressful”.

The IT consultant, 39, mentioned she was initially taken care of with radiotherapy “but despite this she sought substitute medication and therapy”.

Dr Cavet explained Mrs Cockx needed to delay ‘toxic’ remedy so she could have a child initial.

She only makes use of steroids in the course of her pregnancy simply because “chemotherapy was not a excellent idea”, he told the inquest.

Dr Cavet explained it was only since of her youth and fitness the she was capable “to get to the stage of delivering the baby”.

By the time she gave birth: “She had had a lump in her chest that had presently broken her ribs and lumps in her skull that have been developing in various instructions.”

Following the birth, Mrs Cockx had further chemotherapy and a stem cell transplant which initially seemed to operate.

Even so, she later on experienced tremors and fevers – typical side-results soon after a transplant – and referred to Salford Hospital, Greater Manchester.

Sooner or later she was discharged from the hospital and died inside of a number of days – eight months soon after turning into a mother.

Pathologist Dr Leena Joseph informed the coroner’s court that Mrs Cockx died from sepsis and hypersensitivity myocarditis, a drug-relevant irritation of the heart

She told the inquest that the mom died from a complication brought on by one of the healthcare therapies she was on.

Recording a narrative verdict, assistant coroner Sara Lewis, stated: “Nicola’s primary concern was her fertility and the she must have a youngster and of course she did in 2012.

“Obviously it is very tragic that the stem cell transplant could not give a longer remission for her.”

The loved ones are now raising cash for a lot more investigation into the illness on a JustGiving page.

Aggressive Consuming: Is It Dangerous?

As hundreds of thousands of viewers watched in amazement on July 4^th as “Joey Jaws” Chestnut stuffed 61 sizzling canines in his mouth in 10 minutes to retain his 8th title as the reigning champion of Nathan’s Popular Scorching Canine Consuming Contest, this feat–although very incredible in its very own right—raises critical worries amongst health-related pros.

In accordance to the dietary material on Nathan’s internet site, their beef franks contain 170 calories, with 15 grams of excess fat, and 470 mg of sodium.  Doing the math, that is above ten,000 calories, 915 grams of unwanted fat, and above 28 grams of sodium consumed in ten minutes–not to mention the hot canine buns and massive quantity of water to boot.

A Paradox?

Joey Chestnut, at 230 lbs may possibly not seem to be obese.  To get started with, competitive velocity eaters as a group might not appear to be outwardly obese, as some might expect. In reality, a excellent variety of these eaters look to have an common entire body habitus, if not thin in some respects. Individuals who train to be aggressive eaters truly feel that this is a marathon, and those with much less inner physique excess fat are believed to be far more able to stretch their stomachs to accommodate the substantial amount of foods.

But the true situation is what lies inside of and beneath the exterior of the competitive velocity eater.

Some clues are offered by a examine published in the Journal of Roentgenology in 2007 which studied and in contrast two men: a aggressive velocity eating champion, Tim Janus, who consumed 36 hot dogs in ten minutes and a non-competitive eater who had a “healthy appetite”.

In the research, the two men consumed as several scorching dogs as attainable in a twelve-minute period. Results from the study pointed out an important variation amongst the two males: the competitive eater’s abdomen appeared to be massively distended, and there was tiny to no contractions (peristalsis) of the stomach itself, crucial in breakdown and mechanical digestion of food.

What is clear from this study—from a technique acknowledged as fluoroscopy– is that a aggressive eater has the ability to place enormous amounts of meals into the stomach. This capability is feasible by eaters finding out how to overcome the “satiety reflex”. The satiety reflex is what makes you feel complete as you eat greater quantities of meals.  As the abdomen progressively distends, the vagus nerve sends a message to the brain to stop eating.  This reflex can also make you produce nausea and lead to vomiting.

Importantly, aggressive eaters are capable to train themselves to conquer this satiety reflex–so that they can put better quantities of meals into their stomachs without vomiting and without the results of peristalsis.

Medical Worries with Aggressive Consuming

The danger of overcoming the satiety reflex by education oneself to eat progressively larger amounts of food contain long term overstretching of the abdomen which may lead to chronic nausea, and vomiting requiring partial gastrectomy (elimination of the abdomen) in order to reduce symptoms, permitting people to eat normally again.  With a chronically overstretched stomach, the risk of the stomach twisting on itself–referred to as a gastric volvulus—is an additional potential concern.

Other possible emergencies incorporate threat of choking, aspiration, or even asphyxiation–which could outcome in seizures, hypoxia and long lasting brain harm.  Include to this gastric perforation from overdistention of the stomach from unrecognized ulcers in the stomach or duodenum.

And the amazing amounts of water that are ingested  during such contests in a brief period of time can lead to hyponatremia(speedy drop in salt concentration in the bloodstream) and resultant seizures from so called  “water intoxication.”

From a pure dietary standpoint, ingesting huge quantities of calories with a large quantity of excess fat and carbohydrate can overwhelm the pancreas and liver as the body attempts to deal with the huge calorie load. People persons with elevated cholesterol amounts, unrecognized diabetes and preexisting coronary artery condition are at chance for an acute coronary syndrome in this kind of as setting.

Beyond this, the threat for establishing weight problems and hypertension represent ongoing concerns.  With the epidemic of obesity in our society, the notion of obtaining a competitors that values the quantity of food consumed in a short time period of time is ethically unsound.

Last but not least, fasting in planning for competitions, along with the planning needed to train as a aggressive eater is unhealthy in itself. Eating progressively more substantial quantities of food items is inherently unhealthy, putting incredible metabolic anxiety on the heart, liver and kidneys.

Aggressive Consuming: Is It Dangerous?

Most medical professionals would reject aggressive treatment if terminally unwell, examine finds

Clinical associate professor of medication Dr VJ Periyakoil stated: “Why do we doctors decide on to pursue this kind of aggressive treatment method for our individuals when we would not choose it for ourselves? The reasons likely are multifaceted and complex.”

As a geriatrics doctor she understood the disconnect among the kind of care doctors want for themselves at the end of lifestyle and what they in fact do for their sufferers and argued it was not down to physicians striving to make a lot more income or because they are intentionally insensitive to their patients’ desires.

At the core of the issue is a biomedical system that rewards medical doctors for taking action, not for talking with their sufferers, it is argued.

She said: “Our existing default is ‘doing,’ but in any critical sickness there comes a tipping point in which the large-intensity therapy gets to be much more of a burden than the ailment itself.

“It really is tricky, but doctors never have to figure it out by themselves. They can talk to the patients and their families and to the other interdisciplinary crew members, and it gets to be significantly simpler.

“But we never train medical professionals to speak or reward them for speaking. We train them to do and reward them for undertaking. The system requirements to be altered.”

The study examined shifting doctor’s attitudes to a new law made to give patients a lot more handle in excess of determining end-of-life-care choices.

Advance directives are documents that individuals can use to indicate finish-of-life care preferences.

The review involved 1,081 medical professionals who in 2013 finished a net-primarily based innovative directive form and a 14-item advance directive mindset survey at Stanford Hospital &amp Clinics and the Veterans Affairs Palo Alto Overall health Care Technique.

It also concerned 790 medical doctors from Arkansas who have been asked the very same 14 survey concerns – but did not comprehensive an advance directive kind – in a 1989 review published in the Journal of the American Health-related Association.

Remarkably, outcomes showed that doctors’ attitudes toward advance directives have changed tiny in 25 years.

The lack of modify in doctors’ attitudes towards advance directives mirrors what the study describes as the healthcare system’s continued focus on aggressive treatment at the end of lifestyle, despite the truth that most Americans now say they would desire to die at property with no daily life-prolonging interventions.

The examine located A&ampE medics, pediatricians, obstetrician-gynecologists and people in physical medication and rehabilitation had more favorable attitudes towards advance directives.

Radiologists, surgeons, orthopaedists and radiation oncologists have been less favourable.

Pet topics: why is my rabbit so aggressive?

Generally speaking, droppings of any species need to not be eaten (other than some herbivores like rabbits which consume their very own droppings as part of the digestive process). The main problem is that droppings can carry parasites, viruses and bacteria that can be passed on to other creatures. Chicken droppings can carry salmonella, so there is a concern that your canine might, in flip, choose this up.

It’s unlikely that there will ever be a severe problem, but it’s even now anything that you need to get measures to avoid if feasible. Perhaps you could confine the hens to a separate segment of the backyard? If you cannot end the behaviour, you may possibly just have to accept living with the little threat. Just be aware that if your puppy ever develops indicators of gastroenteritis, you need to have him handled professionally, and do not forget to mention his unsavoury routines to the vet.

My son’s West Highland terrier, Benji, aged 9, commenced scratching his rear underbelly two months in the past. Our vet has attempted many treatments, like a program of Prednisolone, to no avail. Can you recommend what may possibly be creating this difficulty and any possible treatment please?

AH, Northwich

West Highland white terriers should be the itchiest breed of all, genetically predisposed to creating skin allergies and sensitivities. However, it can be challenging to pinpoint the purpose for an person dog’s itchy skin, and many diverse brings about (such as meals allergies, mites, an underactive thyroid gland or an overactive adrenal gland) can contribute to the problem. The only way to fix the mystery of most itchy dogs is to systematically perform through a diagnostic process with your vet, or inquire for an even far more expensive referral to a specialist dermatologist.

That mentioned, anytime a canine is itching on the underbelly only, it helps make sense to rule out get in touch with irritation and allergy by preventing the underside of the puppy from coming into get in touch with with anything that may possibly result in an itch, such as floor cleaners or carpets. Wash floors with just hot water, and hold him on tiles and brown paper for a handful of weeks to see if this aids.

My female rabbit was a gentle, loving youngster, but now that she’s a yr old she has turn into terrifyingly aggressive, rushing at me and making an attempt to scratch me with her claws. I have often been gentle with her. Why is she behaving like this and how can I cease her?

MN, Manchester

In most species, it is testosterone, the male hormone, that’s linked with aggression. In rabbits, oestrogen, the female hormone, can have a fearsome impact, producing rabbits behave with out-of-character aggression. I’ve observed humans and other rabbits suffer nasty physical injuries from the sharp claws and teeth of rabbits that are beneath the influence of oestrogen.

The solution is straightforward: you want to get your rabbit spayed. In any case, uterine cancer is frequent in mature female rabbits, so for her very own health’s sake, spaying is the proper issue to do. The Rabbit Welfare Fund (rabbitwelfare.co.uk) has a leaflet called Biting The Hand That Feeds that explains much more about preventing rabbit aggression.

Saying goodbye – the greatest kindness

The Animal Welfare Foundation (AWF) has made a leaflet that guides pet owners through the euthanasia determination-creating method, sympathetically explaining why euthanasia may possibly be the most caring alternative. The leaflet outlines the choices owners have, the diverse ways euthanasia could be carried out and what takes place to the pet afterwards. It also addresses the emotions owners might go by means of when determining to put their pet down. Check out bva-awf.org.united kingdom/pet-care-suggestions to download a copy.
