The real quest of cancer treatment: dispensing the right mix of hope and reality | Ranjana Srivastava

“I just need a letter to say I am fit to fly,” he says, my young patient who has gone from being a paragon of fitness to needing a walking stick in a space of only two years. Today, he is on an unscheduled visit, promising not to stay long, not that I mind. I’m fond of him and have grown to admire the way in which his family has coalesced at a difficult time. His wife left her job, his pregnant daughter has moved in to help, and his two sons are always around for appointments.

But fit to fly? I’m alarmed.

Fly to where? He is pale and gaunt, his eyes magnified on a cachectic face. But his spirit seems valiant as ever, which sends me scrambling to wonder when we had discussed this impending trip, how it slipped my mind, and most importantly, why I had not encouraged it well before these final days of his life.

A flight from Melbourne to Sydney perhaps. Easy and short. Or further maybe, to Alice Springs – difficult but not impossible. Several times I have stopped palliative chemotherapy to honour a patient’s wish to take a trip.

“Where are you flying?” I ask.

“Asia.” he says, and I do a double-take. “They have curative treatment there.”

I should have guessed.

“There is this famous hospital where they give special therapy to kill cancers that have stopped responding to chemo. They sound amazing.”

Every oncologist spends time drawing a distinction between useful adjunctive therapies including reflection, meditation and exercise and dangerous extreme alternatives like exclusion diets and vitamin overdoses, but judging by his tone I calculate that my time would be more wisely spent trying a different approach.

“I am worried about you deteriorating while overseas in a country that has poor hospitals and no palliative care services. I’d hate for you to be stuck”

“I’ve spoken to them, they can fix me,” he says.

“They can’t fix you,” I gently respond. “I know this is really difficult but stay here and let us help you. At least give it some thought.”

Brandishing a manila envelope, he says, “The flight is booked, we leave tomorrow.”

Many retorts, pleas, and memories of misadventure cross my mind, still I hold my tongue, understanding that the measure of grief and the promise of hope amount to much more than the weight of my frustration.

“Doctor,” says my patient. “You have nothing further to offer me, please don’t block my way.”

We arrive at the impasse we had to have.

“I won’t change your mind but I can’t declare you fit to fly,” I say.

At this, I think of the times I have been called to assist ill patients on long-haul flights. Many were emergencies but some not. An elderly lady had felt unwell throughout that day’s dialysis and subsequently suffered an arrest on the plane. “Who cleared her to travel?” I plaintively asked her husband as she drifted in and out of consciousness.

Her situation had stressed hundreds of passengers, distracted the pilot, and put a nurse and me in the impossible situation of resuscitating a patient with bare resources and deafening noise.

I regard my desperate patient with something of my own desperation as I ponder my duty of care. Is it to my patient, reliant on me for a final morsel of hope? Or to all the unseen travellers who may be inconvenienced if by chance he falls ill on the flight?

To temper my pessimism, I remind myself of the grateful patients who didn’t succumb to my dire predictions. The breathless Greek patient who had lived his entire life in Melbourne but who got hold of oxygen and begged to die on home soil. The grandmother who decided that the only way she could make amends to her estranged daughter was to embrace her grandchildren who lived in Egypt. The patient who braved a trip to India by ingesting extra morphine and whose wife wrote to say his final weeks with his whole family had been the most consoling.

This man’s reasons were different but who was I to be impatient around, and judgmental about, people whose decisions departed from mine? So with my patient watching I write the most honest letter I can. It states his wish to seek treatment in a foreign country, my opinion that patients like him can deteriorate unexpectedly, and my sincere hope that he remains safe. He deems the letter fair; his family is clearly displeased.

I feel rattled until I hear that the flight was uneventful. But then the heartache continues because the treatment centre “took one look at him and told him to turn around and go back home”. Which he manages to do before plunging into further decline and succumbing to his illness a short time later in a trajectory that had been predicted.

In the ensuing months the family resists all contact, perhaps feeling angry and let down by all the people who failed their loved one. Meanwhile, the team, too, lacks closure and feels inadequate at not being able to prevent preventable suffering at the end of life.

We muse that perhaps the hardship would have felt worse had they not pursued this last avenue of hope. And maybe the only thing left to give a vulnerable patient is the gift of autonomy. These and other thoughts swirl in my mind, no doubt to be tested in the case of another patient and another patient after that, with every outcome testing and unsettling in its own way.

So many advances in cancer, so many protocols, but still missing is the protocol that says, dispense just this much fact, mix just so much optimism, offer precisely this much warning, infuse just so much hope and things will turn out fine.

For doctors, it’s about how to stand up to – and stand by – our patients to give them the very best of medicine but shield them from the worst. For patients – when to question their own discussions and when to place their trust in ours.

On many days, this seems to be the impossible quest.

Improving NHS services should not feel like a quest in a labyrinth

The surprise in the health service is not how little collaboration there is across professional and organisational boundaries, but how so many people achieve so much in the face of overwhelming odds.

Ministers and NHS leaders encourage and cajole staff to improve services, but even the most driven transformation zealots find themselves worn down by having to fight the system rather than be supported and encouraged by it.

In the words of one GP: “There is a hell of a lot of bureaucracy that gets in the way. The whole thing around designing care is how straightforward it is as a concept, but the bureaucracy cannot disentangle itself from the engineering to allow simple things to happen.

Improving services should not feel like a quest in a labyrinth

“Change can be virtually impossible because money flows will not allow it to happen, so you have teams of people wading through spreadsheets and legal issues. There are boards, frameworks and contracts which create a system that never moves, but people are crying out for a system that allows care to be integrated.”

Arguing that there are ways of working around this misses the point; improving services should not feel like a quest in a labyrinth. On the contrary, a system designed for improvement should be looking for opportunities to sweep away obstructions.

Instead, the NHS has managed to reach the perverse point where a bureaucratic error that allows an member of staff to access patient data without authorisation is treated as a serious problem, but staff not being able to access the notes of someone arriving in A&E is routine.

The imperative to meet national targets irrespective of whether they reflect local priorities is one of the most powerful headwinds. One leading physician described the impact: “We have a significant local transformation plan which will have long-term benefits for mothers and children, and is beginning to gain traction with the local population after a big consultation piece. However, we were threatened with central support being pulled if we didn’t refocus our efforts on our two local trusts’ access and waiting targets.”

Alongside money and staff time, the most precious healthcare resource is data. But too often it is squandered on retrospective beatings around national targets rather than used to inform real-time decision-making and predict future events. Data “tends to be used as whips to constantly show failing, without doing anything to actually change or improve [the system]. It drains resources that could be used to collect more relevant data that would allow people to improve, and find efficiencies.”

Sustainability and transformation plans (STPs) are a credible attempt to get NHS organisations to work together. But while system rhetoric encourages collaboration, outdated accountability and funding rules forces people apart.

The NHS is riven with fault lines. Managers and clinicians look after their own organisations at the expense of others because that is how they will be judged. As one doctor put it: “Drivers, incentives and regulation are the biggest thing. People’s skills have been honed against that backdrop.”

A chief executive said: “The central bodies say one thing and do another. The bottom line is that the regulators are playing politics. You can’t say ‘we are working as a system’ and then say that each organisation has to balance its books.”

I have heard a GP describe a consultant as “the enemy”, not out of personal animosity but simply because he represented the local hospital, the source of most of the difficulties in the GP’s life.

This divisive culture permeates the entire NHS. It can be seen in the poor collaboration between physical and mental health services. I have heard a diabetic consultant admit that he had never met a consultant psychiatrist, despite the high risk of mental illness among his own patients.

There are signs of a more collaborative culture emerging. Leadership and teamwork are increasingly important training priorities for clinicians, and STPs – although subject to stringent oversight – are an attempt to give local leaders at least some power to shape the future.

But creating a system that champions and spreads collaboration and improvement is a long way off. It requires a change of attitude at every level – from the practice manager to the NHS England chief executive – and a recognition that leadership is about liberating the talent below and around you.

Sea Hero Quest is of huge benefit to medical researchers. So what’s the catch? | Emily Reynolds

In tech circles, alongside words such as “scaleable” and “the gig economy”, you often hear the phrase “tech for good” bandied around. Sometimes it’s a fairly innocuous but ultimately toothless concept, essentially denoting the idea that technology has the potential to be a driver for positive social change but not doing very much about it. Other times it can take on a more creepily utopian tone, suggesting that should the world more closely represent the shiny libertarian enclaves of Silicon Valley, the world’s problems would be solved. And sometimes – just sometimes – it does what it says on the tin.

A new game, designed to test spatial navigation, appears at first glance to do just that. Sea Hero Quest, which involves navigating a boat through choppy waters, contains a diagnostic test for the early signs of Alzheimer’s disease. The game has now been played by more than 2.4 million people – which the team behind the game say makes it the largest dementia study in history.

It’s now set to be adapted for use in a clinical setting – data could be fed back to clinicians, allowing for earlier diagnosis, better understanding of how medication is working for a particular patient and a more accurate and precise measurement of a patient’s decline. It could even be incorporated into NHS programmes.

This, it goes without saying, is initially incredibly attractive. Understanding and managing an illness or being alerted when you’re at risk simply through the daily use of an app sounds simple, easy and most of all useful. Could this not be a genuine use of tech for good, rather than the banal and empty proclamations often heard from CEOs and founders?

In theory, yes. In practice: maybe not.

As with any health data-driven project, it comes with stipulations. A recent study in Lancet Psychiatry suggested that data gathered on Facebook could provide a “wealth of information” about mental health, with a series of language analysis and facial emotion recognition algorithms providing “insights into offline behaviours”. This, too, sounds great. Having your health monitored and managed through the passive use of technology you probably already use – what more could you want?

But there are a number of concerns here: primarily, the safety of private health data. The addition of a private company in the latter study may make it feel different: a towering behemoth such as Facebook obviously feels more threatening than something set up for and run by clinicians. But to not have the same reservations just because the data was being sent to scientists would be incredibly naive.

Science, much like technology, is often presented as objective, reasonable fact, without mentioning the very obvious caveat that it is conducted by human beings, who are often neither reasonable nor objective. Multiple studies about statistical analysis are useful to recall here – the results of such analyses may seem completely objective, but often reflect the preconceived biases of those conducting them. That’s not to say that would be the case with Sea Hero Quest, of course: just that the results of such research can be fallible.

And it’s also important to remember that, should the Conservative party have its way, the NHS may be in the hands of several, separately operated and privately owned companies before too long. This adds further complications: who would have access to our health data? How would they use it? How would data be efficiently and safely communicated across different companies? Would their data protection processes be cohesive? Would they be meticulous enough to protect our most private, personal data? The idea of having your phone feed data to a central NHS database sounds great in principle, but these questions would need to be answered before that could safely become a reality.

In an ideal world, tech would be utilised to help us to diagnose and treat illnesses: anything that can efficiently and effectively help people manage long-term or life-threatening conditions can only be a good thing. Similarly, the idea of a National Health Service that is genuinely innovative, that uses new ways to help people and that has a strong grasp on data security while it does so is incredibly appealing. Unfortunately, as with most utopian ideas, you’re left wondering whether it might just be too good to be true.

Sea Hero Quest: the mobile phone game helping fight dementia

A mobile phone game that tests spatial navigation skills and has been played by 2.4 million people, has become the largest dementia study in history and raised hopes of a breakthrough in diagnosing the disease.

Sea Hero Quest, a collaboration between Alzheimer’s Research UK, Deutsche Telekom, game designers Glitchers and scientists, has generated the equivalent of 9,400 years of lab-based research since its launch in May.

Experts hope to use the data to create the world’s first global benchmark for spatial navigation, one of the first abilities affected by dementia, and to develop the game into an early diagnostic test for the disease, which is the leading cause of death in England and Wales.

Dr Hugo Spiers, of University College London, who presented the preliminary findings at the Neuroscience 2016 conference in San Diego, said: “This is the only study of its kind, on this scale, to date. Its accuracy greatly exceeds that of all previous research in this area. The findings the game is yielding have enormous potential to support vital developments in dementia research. The ability to diagnose dementia at early stages, well before patients exhibit any signs of general memory loss, would be a milestone.

“This study is thus now giving us the opportunity to make a real difference to the lives of millions of people living with dementia and those at risk of developing the disease in the future.”

Sea Hero Quest requires players to navigate a boat through waters in differently themed areas over 75 levels, collecting items along the way. It was designed to appeal to all gamers, rather than just people wanting to contribute to a good cause, and its popularity has seen the number of players soar past the original target of 100,000 by the end of the year.

Players provide their age and sex, allowing the scientists to chart their performance against other users.

Spiers said they could now create the equivalent of a height chart whereby if someone was particularly short – or in this case if their spatial navigation ability was particularly low – for their age and sex it would raise a red flag.

By testing a person’s spatial navigation abilities, the game could allow for diagnosis and treatment of patients far earlier.

Spiers said Sea Hero Quest, which will now be adapted for use in a clinical setting, could also be used to track decline and in drug trials to test the impact of the medication.

Alzheimer’s Research UK’s chief executive, Hilary Evans, praised the role of Deutsche Telekom, which has spent more than €1m (£860,000)on the project, including marketing.

“The early data that has very quickly been generated by Sea Hero Quest should inspire other corporations to consider what assets they might bring to research into dementia or any of our most seemingly intractable medical conditions,” she said.

The experts found differences in spatial navigation strategies employed by men and women, and also that spatial navigation abilities began to decline from early adulthood. For example, players aged 19 (the youngest in the study) had a 74% chance of accurately hitting a target during the game, compared with 46% among 75-year-olds (the oldest in the study). This decline over time contradicted previous studies – typically based on less than 100 people – which suggested cognitive abilities do not decline until later in life.

They also found that players in Nordic countries showed notable spatial navigation capabilities.

The scientists will carry out further analysis of the data over the next two years. In the meantime, the game continues to be available for free download and the data generated will contribute to the ongoing research.

Fashion industry told to end its quest for ‘unattainable thinness’

The Women’s Equality party is to launch an unprecedented campaign aimed at radically changing the way the fashion industry treats body size and shape.

Coinciding with London fashion week, which will run from 16-20 September, the initiative will call for an end to unrealistically small “sample sizes” – the sizes in which designers show their new creations – and demand a minimum body mass index (BMI) for models.

Sophie Walker, the WEP leader, plans to ask the London mayor, Sadiq Khan, to withdraw funding for next year’s fashion week if the campaign’s key demands are not in place by then. She will also ask Maria Miller, chair of the Women and Equalities Commission, to hold a public hearing in which fashion designers will be asked why their clothes are based on “an unattainable level of thinness in women”, which Walker believes is contributing to a crisis in public health with an economic impact of £1.3bn a year.

The campaign calls for models whose BMI is below 18.5 to be seen by a medical professional from an accredited list, who will judge whether they are well enough to be employed by a modelling agency. Similar legislation exists in France, Spain, Italy and Israel. Campaigners are also asking that fashion designers showing at LFW commit to including at least two sample sizes in every range, one of which must be a UK size 12 or above.

Additional proposals include fashion magazines committing to at least one piece in each issue featuring plus-size models. WEP is also demanding that body image awareness become a compulsory part of personal, social and health education, with a focus on media depictions of beauty and extra training for teachers.

Those backing the campaign include Caryn Franklin, the former presenter of The Clothes Show, who is now a professor of diversity in fashion at Kingston University, plus-size model Jada Sezer and model Rosie Nixon, who has spoken out against an industry that asked her to lose an unreasonable and unhealthy amount of weight in order that she get “down to the bone”.

WEP will also launch an interactive social media campaign, #NoSizeFitsAll, based on the statistic that one in five women cut the labels out of their clothes to conceal their size. A photoshoot will feature new designers Isatu Harrison and her line, Izelia, and Katie Pope of Pope London, both of whose work will be modelled by a diverse group of women.

Walker describes the initiative as a chance to “raise awareness of the body image issues experienced by women and girls, and to have a discussion about the significant and far-reaching impact of the fashion industry’s idolisation of a unique and very small size”.

Breakthrough created in quest for new malaria medicines as resistance fears expand

Australian researchers have created a significant breakthrough in the race to discover new medicines to eliminate malaria, as resistance increases to the only drug left to treat the ailment.

Scientists from the Burnet Institute, Deakin University and Monash University were in a position to starve the malaria parasite of crucial proteins important to its survival, delivering a target for the improvement of new antimalarial drugs.

The malaria parasite exists inside a red blood cell – which permits it to go undetected by the immune technique, but is not an excellent atmosphere for the parasite to expand and thrive.

A co-writer of the paper, published in Nature, Tania de Koning-Ward from Deakin’s medical school, stated it meant the parasite had to “renovate” its setting by sending hundreds of its own proteins into the red blood cell for it to feed on.

“What our study has proven is individuals proteins can only get accessibility to the red blood cell via one gateway, which provides a channel for the proteins to get into the red blood cell so that it can reside and multiply,” she explained.

“We managed to alter the perform of this gateway so that these proteins can no longer get into the red blood cells, starving and killing the parasite.”

In 2009 researchers first discovered the malaria parasite obtained the proteins it essential by means of a gateway. But they were unsure whether blocking that gateway meant the parasite would basically uncover one more one. Parasites are notoriously great at adapting.

That meant convincing drug companies to invest in establishing medication to block the gateway had been a hard sell till now, De Koning-Ward explained.

“What we have shown by way of this analysis is the parasite utilizes just this a single gateway to acquire these proteins, which makes that gateway a excellent target for drug therapies.”

As parasites create resistance to drugs, researchers usually tweak them slightly to make them tougher for the parasite to battle. But the parasite often speedily develops resistance to the newer versions.

Artemisinin – the only drug left to deal with malaria – and the drug that came just before it, chloroquine, the two worked by offering the malaria parasite what was primarily a negative situation of indigestion, avoiding it from being able to eradicate a construct-up of iron that takes place right after it ingests haemoglobin.

Another co-author of the review, Dr Paul Gilson, senior investigation officer at Burnet Institute, stated the new research meant drug firms could now change their tactic totally. Alternatively of blocking the parasite’s capacity to detoxify the iron ingested, they could target the gateway it employed to get the “food”.

“It implies that when a drug that blocks the gateway is created, it may possibly get a whole lot longer for the malaria parasite to develop resistance to it, since it will never ever have witnessed a drug like this just before,” he said.

Resistance to artemisinin has previously occurred in parts of south-east Asia.

Gilson believes medicines that target the gateway could be prepared inside a few years, but explained they would then want to undergo trials that could get up to an additional ten many years.

“But the cupboard of medication obtainable to treat malaria is at present quite bare,” Gilson stated. “Our study supplies an critical new target for drug development.”

Malaria is spread via mosquitoes and its most lethal form is caused by the parasite plasmodium falciparum. More than 200 million people get malaria each and every 12 months and far more than half a million of those, mostly young children, die from the illness.

The speedy development in population movements meant there was a chance resistant malaria might reach other countries more speedily, Gilson explained. Whilst resistant malaria is not impossible to treat, it takes a whole lot longer.

Australian researchers have created a significant breakthrough in the race to discover new medicines to remove malaria, as resistance increases to the only drug left to deal with the disease.

Scientists from the Burnet Institute, Deakin University and Monash University were ready to starve the malaria parasite of essential proteins important to its survival, offering a target for the growth of new antimalarial medication.

Yet another co-writer of the review, Dr Paul Gilson, senior research officer at Burnet Institute, stated the new analysis meant drug companies could now alter their tactic entirely. Rather of blocking the parasite’s capability to detoxify the iron ingested, they could target the gateway it utilized to get the “food”.

“It indicates that when a drug that blocks the gateway is developed, it could get a good deal longer for the malaria parasite to develop resistance to it, due to the fact it will never have noticed a drug like this ahead of,” he stated.

Resistance to artemisinin has presently occurred in elements of south-east Asia.

Gilson believes drugs that target the gateway could be ready inside a few years, but explained they would then need to undergo trials that could take up to another 10 many years.

“But the cupboard of medicines offered to deal with malaria is at the moment rather bare,” Gilson said. “Our investigation provides an essential new emphasis for drug development.”

Malaria is spread through mosquitoes and its most lethal kind is induced by the parasite plasmodium falciparum. Far more than 200 million people get malaria every year and more than half a million of those, mostly youngsters, die from the illness.

The quick development in population movements meant there was a risk resistant malaria may possibly attain other nations more swiftly, Gilson explained. Even though resistant malaria is not unattainable to deal with, it takes a great deal longer.

A Massive Quest For Good Genes That Shield Us From Undesirable Ones Begins

Stephen Pal (seated) and Eric Schadt (onscreen).

What if the very best clues to curing genetic illness are not in the ailment genes themselves, but in the resilient genes of those who who somehow really don’t turn into unwell?

That’s the idea of a new research examine launched yesterday by open science advocate Stephen Good friend president of Risk-free Bionetworks, along with an article in Science, the analysis journal, and a TED talk explaining the venture. Friend and his colleagues hope to hunt via far more than a million men and women in buy to uncover a few who have genetic variants that ought to have killed them in childhood, but who have made it to age forty or older.

“Maybe we’ve been hunting as well lengthy at those who are sick,” says Pal, “and the better way to do it would be to assume that if you wished to create a therapy for prevention, shouldn’t you appear at people who should have gotten sick and did not.”

Friend, who has had profitable turns as a cancer researcher, a biotech CEO, and the head of cancer research at Merck, calls the hard work, referred to as The Resilience Undertaking, a single of the most thrilling he has ever been concerned with.

The thought dates back to the operate of Nobel laureate Lee Hartwell, with whom Buddy commenced a biotech company in the 1990s. In February 2001 Hartwell wrote an report in Science proposing that researchers need to be concerned far more about what he called “buffering.”

Just possessing a gene variant, even for a terrible disease like cystic fibrosis, which fills the lungs with mucus, leads to digestive difficulties, infertility, and early death, may not usually suggest you get sick. Geneticists call this “penetrance” – the trait a gene codes for might not penetrate into the physical signs and symptoms of a person. This, Hartwell argues, is because there are most likely other gene variants in the body that are trying to keep the undesirable gene from doing harm.

Great theory. But why does Pal think discovering these genes is even plausible? Simply because he did a check run. He teamed up with Eric Schadt, who worked for Pal at Merck and now directs the Icahn Institute for Genomics and Multiscale Biology at the Mount Sinai School of Medication. They have been in a position to get anonymized samples from a lot more than half a million individuals from databases which includes the 1 kept by genetics startup 23andMe, and from them they identified ten people who look to carry genes that lead to 12 illnesses, which includes unusual but deadly illnesses cystic fibrosis, Gaucher’s disease, and MPS II. Friend calls them “unexpected heroes:” men and women whose genomes might hold hints at how to

The problem: due to the fact of the way the information had been collected, they can not simply go back to those people to study them. So they want to commence the search anew. “All we need is info,” Good friend says in his TED talk. “We need to have a swab of DNA and a willingness to say, what’s inside me? I’m prepared to be re-contacted.” Patients can indicator up through the project’s web web site.

Even once individuals folks are discovered, the energy will not be more than. “It’s a massive challenge,” says Daniel Macarthur, a genomics researcher at Massachusetts Basic Hospital. The unexpected heroes will be so small in quantity that conventional genetics will not be able to locate the protective genes. Instead, Good friend and Schadt say, they will place people people’s genes in model organisms like mice. They will generate induced pluripotent stem cells of the heroes’ DNA, and review those. Other groups will study their cells making use of new tactics like CRISPR, which enables scientists to do targeted genetic editing to figure out what transpires when distinct alterations are produced to a cell’s DNA.

If the effort comes up dry on obtaining protective genes, MacArthur says, just studying a lot more about how frequently disease genes actually cause ailment will be hugely useful for scientists.

But genes are not destiny not only simply because of other genes, but due to the fact of environmental factors, also. Pal and Schadt have tied up with the National Institute of Environmental Wellness Sciences. Lisa S. Birnbaum, the Institute’s director, says that the effort could be “a treasure-trove for geneticists, epidemiologists, biostatisticians, and possibly all biomedical researchers.”

“Most folks believe of your genes, heredity, and setting as hazards,” Friend says. “There’s this concern among the public that you would by no means want to know what is going on, that the genes are all bad. What we’re trying to say is we would never ever be right here if there weren’t for this point of energy we deliver with us: Not the poor mutations but the great that actually allow us to survive.”
