A Shiny New Blog and Web Address

Hello all,

Just to let you know that I've moved over to another blog at another address. The new one is miles prettier. I've moved all of my old posts over and will be posting new ones over there only, so make sure that you change your bookmarks and all of that kind of malarkey.

I'm going to look into trying to sort out automatic redirection, but in the meantime, make sure you head on over to:

The beauty of disagreement

If this skepticism lark has taught me anything, its that disagreeing is a beautiful thing. Disagreeing with someone is a hard thing to do, in any context. Yet as humans, health care professionals, and as skeptics, its one of our keenest tools. Its only by being able to step into disagreement that we can understand our topic, our audience, and hopefully steer hearts and minds away from those willing to mislead.

I recently attended a panel about daring to disagree, which mainly focused on religious debates over Twitter and the like. I'm guilty of wiling away hours of my life arguing with homeopaths over twitter, and I'm often asked why, as I'm never going to change their minds. The short, and most noble answer is that someone undecided might spectate, and I might be able to make some impact into how they think about the subject. The more self-serving version is that its good practice to hone my skills in identifying fallacies and flaws, finding workarounds and ways of wording things, and to understand an argument in advance of the next time. In these types of arguments, the people who you are speaking to are removed from yourself, perhaps not anonymous as such but they tend to be used to arguing. Their position is usually on the defensive in the first place because their chosen subject has usually been the butt of skeptical inquiry for years.

But what of those closer to home? Sticking out heads up above the parapet in other situations is one of the hardest things in life to do. Most of us instinctively see disagreement as a threat and a personal attack, and we react accordingly. Even now, despite all I've learnt about constructing arguments and debates, with all of this practice, I certainly still get physical reactions when someone disagrees with me. My heart will pound, my mouth with become dry, and I'll want to curl up in fear because my body and brain immediately leap to the conclusion that no one likes me, that I'm so insignificant that I must automatically be wrong. I'm thankful to skepticism in that I'm able to take a deep breath and overcome those initial few moments, then can try to reassess my position. Am I actually right, but there are some good points to take away from the other stance? Or actually, is my reasoning flawed? In which case, why? Where could I have found more information, what is the other person bringing to it? Whichever way it goes, I, and the other person, end up learning more. Ultimately, we're not here to be right or wrong- we're hear to learn more, and that's the important bit.

Problems arise though because often our instincts take hold. I can't describe the number of times its all gone tits up. I can spend ages agonising over whether or not to disagree. Once I've decided to do so, I write and rewrite my argument so that it is as objective as possible, structured clearly, evidence based etc., only to have the response be “Eurgh why are you being so mean?! I thought we were friends!” or similar. I've tried all sorts of ways to word things, and I haven't quite come up with an answer on how best to avoid this response. Its not just Facebook etc. where this is a problem- we all hear in the news about irrevocable breakdowns in the doctor-patient relationship (Ashya King, as an example). We've all encountered the patient at the pharmacy counter who believes a random person waiting in the queue over our own expert advice. No one learns anything from these sort of exchanges, and that's a real missed opportunity.

So the question is, how do we go about promoting disagreement as a positive thing that we all need in our lives? How do we turn the tables on the thousands of years of evolution that make us shut down arguments as soon as they begin? Well I think the answer has to initially come from example. I believe the skeptical movement is extremely well placed to start this tidal change in thought, but we all have to practise the heck out of it every single day if we're ever going to get anywhere. We have to start being known synonymously as folk who are really, really good at disagreeing respectfully, and that has to start from within. Its clear that the skeptical community in the UK and beyond occasionally falls short in this regard, and that's a real shame as it appears to be driving good people away.

We need to recognise that we might agree with someone on one thing, but not the other. We can't see a person as synonymous with one of their opinions, and put people in good or bad boxes based on that. We shouldn't be labelling people as anti-this, or anti-that, and then refusing to engage further. We should be experts at digging deeper than that, looking behind the headlines to search for shared humanity underneath. We need to lead the way in disagreeing without bullying, and we should never, ever let up on that. We put ourselves in a position that could so easily be mashed up together with bullying by the general population when we dare to disagree, and we need to be relentlessly exemplary in our behaviour to prove that we aren't. We need to be the type of people who, even if faced with a mutant hybrid of Nigel Farage and Piers Morgan, would manage to keep their cool and be polite.

But then again, feel free to disagree ;)

Allergy Relievers: Red Light Nonsense

Its just about coming into allergy season again, so today I am turning my attention to a product I’ve seen for sale in a few pharmacies I’ve locumed at of late: The Allergy Reliever Device. These things are sold under some pharmacy chain’s own names, or under brand names like Kinetik.

It’s yet another medical device. These things seem to be hitting the pharmacy shelves more and more often these days, giving them a level of respectability which personally I don’t think they deserve. At least this device makes it clear that it is a device though, unlike things like Prevalin which pretend to be real medicine.

According to Kinetik, it uses “red light therapy to suppress the cells that release histamine, thereby relieving the symptoms of hayfever and allergic rhinitis.

So, essentially shoving some Christmas tree lights up your nose then. Well I must admit that’s a new one on me. It’s pretty hard to sniff out (geddit?) the theory behind this one too.  The manufacturers of these things don’t give any explanation as to why red light would suppress mast cells, and several Google searches later I’m none the wiser. I have managed to dig out one published paper in rats, where the authors seem to be suggesting that red light changes the redox state of cells, which might cause some changes within the cell. Even these others say that they’re not quite sure what’s happening though, and that further investigation is required.

Armed with a few unsuccessful Google Searches, I delved into the medical literature. I tried every which way I could think of to search for evidence that this thing works, but ended up drawing a total blank. I think this may well be the least successful search for evidence I’ve done so far, and that’s saying something. Even the manufacturers can’t be bothered with listing any sources instead they go wild with the clipart, giving us a Generic Smiley White Coated Person and Happy Photostock Chef alongside some very random recipes and general lifestyle advice.

And it looks like this thing really isn't very pleasant or practical to use. You're supposed to shove the probes up your schnozz as far as you comfortably can, then keep them there for three minutes. Not the most dignified of poses. And you're supposed to do this three or four times a day. That's a lot of inconvenience. Seems like prime Use Once Then Put In A Dark Cupboard territory for me, especially since taking a one a day antihistamine tablet is no hassle at all. 

In short, I wouldn’t waste your money. There’s no basis to these things, and it saddens me that they are not only being sold in pharmacies, but are being sold under pharmacy brand names. The more we associated our profession with such nonsense, the less trustworthy we become to other healthcare professionals and patients alike.

"I do my own research"

Something that I see a lot in on-line debates about alternative medicine is phrases like “I did my own research” or “people should be allowed to do their own research and make their own decisions”

However, I don’t think that the vast majority of people are able to do their own research. Now, that’s probably a pretty unpopular opinion. It’s patronising, paternalistic, and it flies in the face of patient choice. Who am I to question the intelligence and abilities of other people? Why do I think I'm so clever compared to anyone else out there? Allow me to explain myself.

I've been a pharmacist for a very long time now. From uni, through pre-reg, to my own revision at work, I've been taught critical appraisal skills. Yet to this day, it’s something that I actually find really hard work. It’s a skill that requires continual honing, and every time I use it I feel like I am fighting with my brain.

Even in the last two weeks, I've been revisiting my critical appraisal skills to make sure they are up to date. I've done some in-house work, three on-line courses, and a one to one training session. Yet I still find myself sat here at my desk for several hours, if not days, looking over the same study with a furrowed brow, desperately trying to make the numbers and statistics tell me their story.

There’s hazard ratios, odds ratios, confidence intervals, numbers needed to treat, event rates, absolute risks and other confuddling terms to deal with. I naturally struggle with numbers at the best of times; like most people, I much prefer narratives. That means that I have to constantly argue with myself to keep looking at the results page, rather than just flicking to the discussion. Becasue if I did that, I'd be relying on what the authors, with all of their possible biases and agendas, say their numbers say. Then, when I eventually manage to squeeze the swimming mass of figures into some sort of order in my head, I find out that these numbers aren't the full story, and I need to dig even deeper into other analyses of the same figures to find out what’s really going on.*  

A quick and very simplistic visualisation of all the layers of interpretation that might lead to information found on your common or garden health information website. That's a whole lot of bias. 
I am truly terrible at MS paint, but you get the idea. 
What a typical EMBASE search looks like. This is for a new drug with few synonyms so its a fairly straightforward one. Others can have forty odd lines of searches. 


It’s not a pleasant task by any stretch of the imagination. It really does feel like a mental marathon. I often question whether I am even up to the task- I can end up feeling stupid, and confused. But in order to really figure out whether or not a drug works I need to strip away all the levels of other peoples’ interpretation and start from scratch, with the cold, hard, impersonal numbers. That way I can build my own narrative, uninfluenced by what the study’s authors or sponsors want me to think, by what newspapers want me to believe, by what campaigners want me to know. The only way to know the truth is to start right at the bottom, in a dark dank pit of statistics, then to slowly start building yourself a ladder until you emerge, blinking, into the pleasant knowledge that you've worked out what on earth is going on.

This sort of raw data is not only extremely hard to deal with once it’s in front of you, but its also pretty difficult to come by. Finding it in the first place includes searching multiple medical databases- and these things aren't just a quick free text search like you would do on Google. Constructing a search can in itself take an hour or so, and then you have to trawl through the results to decide which are relevant to what you are specifically looking for. For me, most of the time, a question is structured like this:

What is the evidence that [drug/ group of drugs] works for [disease] in [patient group]?
                                                        
So, in my poorly drawn Venn diagram below, I need to find those holy grail papers that reside in the pink area:


Some of these papers might be pay-walled, so it’ll take me a week or so to get my hands on them. Some of them might initially look promising, but once you start to dig down into the figures you see that there might actually be problems with how they were undertaken or reported, or they might turn out to not quite fit in some way- perhaps the dose they used in the trial is different to the licensed dose in the UK, or the people enrolled into the trial don’t quite fit the population you want to know about, or perhaps the trial just didn't recruit enough people so any results from it are invalidated.

I've been doing this job for years, and I really do still struggle with all of this stuff. That’s not because I'm poor at my job, or because I'm stupid, or because I haven’t put the effort in to understand it. It’s because, when it comes down to it, this stuff is really bloody hard. It’s time-consuming, boring, and unintuitive.

People might well feel like they've done their own research. They might spend several hours digging about on the internet and feel empowered by any decisions that they make. But what they don’t realise is that what they've been researching isn't just the information- it’s the information with many, many layers of interpretation (and therefore bias) added. For a choice to be truly informed, you need to go right back to the start, to those terrifying tables of numbers and statistics. That’s simply not realistic for the majority of people.

Far better, then, to learn how to decide on whose interpretation you’re going to rely on. Will it be those that take the media reports at face value, or who have an agenda or a product to sell you? Or will you go with those that have years of training in how to pull apart complicated data and disseminate it in understandable ways?

*I thought I’d give you a quick real life example here, but I thought it best to asterisk it because I've probably bored you enough already. I'm currently looking at a drug called edoxaban and its use in reducing the risk of stroke in patients with atrial fibrillation. It’s the newest in a series of  novel oral anticoagulant drug- they’re supposedly like warfarin, but less faffy. So I find and look at the main trial, and spend days unpicking the stats. It looks like both strengths used in the trial are no worse than warfarin, and the higher dose might even be a little better. Great, right?

Well, that’s not quite the end of the story. Because it turns out- and this isn't reported in the trial at all, but instead is contained in the FDA’s briefing document- that in people with fully working kidneys, edoxaban is actually worse than plain old warfarin. In people whose kidney’s aren't quite at full capacity though, it might work better than warfarin. So the overall trial results are kind of skewed, and if we didn't dig deeper, we might have been giving a whole group of people a more expensive drug with worse outcomes than warfarin.

Why I'm not a member of the RPS

Since there's a whole load of people tweeting their reasons for why they've renewed their membership, it seems like a really good time to discuss my reasons for not renewing.

Historically, membership of the Royal Pharmaceutical Society of Great Britain was mandatory, as they acted as both a professional body and a regulator. Their fees were huge- £400+, and they had a reputation for being very meek and for being a bit of an Old Boys Club. Then the split occurred, and now we pharmacists have to pay the regulator, the General Pharmaceutical Council, but we can choose whether or not we want to fork out for RPS membership. When I was working towards being a pharmacist, I was so excited and proud to be part of a professional body. I'd love to still feel that way today, but there are a few things standing in my way. Some of these reasons are very personal to me, whilst others I think may resonate with many. I can but hope that if they are read by anyone at the RPS, my comments are taken as they are meant- constructively, and with a hopeful heart that one day I will be convinced enough to renew my membership with them after a long hiatus.

1. Cold, Hard Cash

Membership of the Society costs £192. That's a lot of money. Surprisingly, that's not a popular opinion- whenever I say so on Twitter I am hounded by comments like "It's only the price of a pint of beer per week" or "just give up your morning coffee!". The inference is that my priorities are all wrong, and I must be mad to not join for such a reasonable price.

A few years ago, I really was in financial trouble. It was a combination of things, including a divorce, that got me to that point. Some of those things were my fault, some weren't, but none of that mattered when I had ran out of my overdraft and an enormous bill was overdue. I'm now at a much more stable point in life, but that time is still fresh enough in my memory that £192 is still a lot of money for something non-essential.

2. Attitude towards poverty and Other Snark

There have been a few occasions when I have mentioned that I can't justify the cost on Twitter, and as mentioned above the response has been rather eye opening, sometimes from RPS staff. It would appear that there is a complete lack of understanding of financial difficulties from some quarters. You try to explain that yes, it might just be the price of a pint per week, but if you haven't got the price of a pint in the first place it makes no difference, but that concept just does not appear to compute. Some of these conversations got so bad that I had people DMing me to check that I was okay.

I've been made to feel ashamed and belittled. This may not have been intended, but this general conception that pharmacists- presumably because they get paid fairly well- must never have real money worries is really concerning to me. A good wage is brilliant, but it doesnt 100% guarantee such financial security that £192 seems like a throwaway amount. Sometimes life just steps in and mucks everything up. As health care professionals, empathy is an extremely important skill, and there have been a few occasions were that seems to have been lacking. If folk can be so dismissive of financial hardships, what else could they be similarly judgemental about?

Additionally, I did see another, unrelated snarky tweet by a very prominent member of RPS staff to a tweeter who had dared to ask for evidence. This may be a very minor thing, but to me its a big no-no, since I'm so passionate about evidence based medicine.

I wish I had screenshots of all of these conversations, but they happened a long time ago and I'm too tired to try to hunt them out. I know this might all sound super petty, but for an organisation with professionalism at its very heart, I think such seemingly small things add up.

3. Evidence of Value for Money.

The RPS certainly does some very good work. And I can honestly say that I hugely admire their improvement over the years that I've been a pharmacist. They're a lot more visible these days, a lot more proactive. I've admired their stance on things like social media, homeopathy, and e-cigarettes. I love that they've collaborated with Sense About Science. But, despite all of these advances, I'm still not entirely convinced that membership would make enough difference to my daily life to justify a cost of £192. How do I know, if I'm not a member? well, I know this isn't particularly robust, but from my own n=1 experience of previously being a member compared to now, I see no difference.

I've never had a patient look at my credentials and say "Here, you're missing an R and an S from your MPharm, you must be a rubbish pharmacist.

4. Money=Professionalism

This is a concept which I simply cannot abide, but which is creeping more and more into the forefront. It seems that organisations are starting to equate RPS membership with professionalism, and this is very simply not the case. Throwing money about does not, under any costs, make someone more professional. I know some really terrible, unethical pharmacists who are members. Homeopathic pharmacists who repeatedly endanger peoples' lives, in spite of the RPS stance on homeopathy, appear to be members. Then there's me, who works bloody hard to be a good pharmacist, to promote safe and effective healthcare, and who spends sleepless nights worrying about my patients.

What of those of us who work our asses off, day by day, to help our customers, pay our bills and maybe, if we're lucky go on a little holiday? The implication that people who cannot afford membership are somehow less professional really, really drives me mad, and far from making me rush to hand over my cash, it instead distances me further.

5. Previous personal letdowns

I've written previously about a complaint against me when I was newly qualified, which was handled by the  RPSGB. Although they no longer deal with complaints, I was left with a lasting sour taste in my mouth following that experience. I spent a lot of time with the inspector, talking about the substandard working conditions I was being forced to work in at the time. I was assured that the RPS would fight to improve those standards, and that they would be taken into account. Of course there was no mention of that conversation in the report i later received.

I know this is anecdotal, and I know its unfair to tar the current RPS with the same brush as I did their predecessors. But it does mean that to me personally, they need to work a little harder than usual to win back my trust.

My Joining Threshold

I'm not entirely sure of what would convince me to join as of yet. This is still, despite all of these years, pretty nebulous and shifts occasionally. Some of my admittedly vague suggestions where there is room for improvement are:

  • Guiding a sea-change in the profession to embrace evidence-based medicine. 
  • Speaking up about the amount of unprofessional quackery for sale over pharmacy counters. 
  • Truly standing up for everyman: acknowledging the importance of every pharmacist out there with aching feet and a headache who hasn't had a proper lunch break in years. 
  • Shaking off the traditional top-down culture of the profession and finding creative new ways to really listen to those of us working at the front line- those of us who can't get the time off work to attend meetings in London and who are too exhausted at the end of our 16 hour shifts to spend hours reading consultations .
  • Making some really meaningful steps towards changing poor workplace conditions for pharmacists.
  • Constructively engaging with non-members in order to raise the profile of the profession cohesively, rather than creating a false, unhelpful two tier system
  • Working towards breaking through mental health stigmatism both for patients and within the profession. 
The other important factor for myself is of course financial stability. I'm getting there. I'm not ashamed to say that at the moment, though, I'd rather prioritise that pint per week over membership. My social life is extremely important to me- its what has gotten me through the hard times, and I can see a clear benefit to my life from it. At the moment, sadly, I can't quite say the same about RPS membership, though hopefully in time I will be persuaded otherwise.

Special Investigation: Is Santa Really A Pharmacist?

Despite him being one of the most famous people on the planet, we know a suspiciously small amount about Santa Claus's background. I've had the suspicion for some time that he may in fact be a pharmacist throughout the rest of the year. 

A quick check of the GPhC register brings up no S. Claus’s, though of course that only rules out pharmacy practice in theUK. Unfortunately it would seem thatLapland does not have a similarly searchable pharmacist register, so we are unable to confirm his registration status in his home country. However, if Santa were to be working overseas, it would seem that Your Family Pharmacy, 15 N Kringle PlaceSanta ClausIndiana would be his first choice, especially given its prime location near to Lake RudolphCamping Park. (honestly, this place exists)

Santa is, of course, most famous for operating a highly efficient free delivery service. No doubt these skills have been honed throughout the rest of the year, as he organises a prescription collection and free delivery service to his patients.

As the song goes: “He’s making a list, he’s checking it twice”, demonstrating that Santa is following robust self-checking procedures. It is clear that he has the sort of attention to detail that is required by pharmacists. It’s also clear from this song that he is aware of NICE guidelines.

It seems clear that Santa’s system of working, is synonymous of that in a community pharmacy. He works alongside a team of highly skilled and well trained elves, though retaining legal responsibility for all that goes on in his workshop. One assumes that, on visiting the workshop, his Responsible Father Christmas sign is clearly displayed.

Perhaps the most convincing evidence is that of his links with the Coca Cola company. Santa has a long history of advertising the product, adding a splash of red and a liberal helping of fur to his usual pharmacy white coat. Its good to see that Santa is so devoted to advertising the invention of  fellow pharmacist John Pemberton, who originally invented the drink as a cure for his own morphine addiction. Santa is clearly interested in harm reduction and no doubt works closely with local drug and alcohol teams during the rest of the year to dispense opioid replacement therapies for patients.

Santa Claus, however, does have some flaws as a pharmacist. As discussed in the BMJ, he appears to pose a number of public health risks, including as a vector for infectious diseases, and in the promotion of drink-driving. It would seem that he would benefit from a visit to his nearest Healthy Living Pharmacy, where he can access advice on reducing his weight and brandy intake. It is good to note that he successfully quite smoking and seems to have remained abstinent.

The Difference A Year Makes.

“Maybe this Christmas will mean something more
Maybe this year love will appear
Deeper than ever before
-Tracey Thorn, Maybe This Christmas

This time last year, I was writing this post, collecting together songs that I felt best summarised why I find Christmas such an emotional time.

Of course, I’ve been listening to that playlist on repeat for weeks this year too, but it sounds different to me this time round. Its transformed from a quietly melancholic collection to one of optimism.

This time last year, I was steadfastly single. I refused to believe in love in the same way I used to do in the past. I had never even said the word to anyone else (except for friends) for years. I was stubbornly resisting the advances of a man who I knew to be very wonderful, on the basis that I would likely just mess it all up anyway and hurt him, given that I was, in my own head, such an awful and cynical heartless monster who would clearly ruin his life.

Luckily, my willpower (helped along by a fair amount of beer) failed me eventually and we went on a date in January. This is probably the best decision I have made, ever. What has followed has been better than I could have ever imagined. I’ve gone from refusing to acknowledge the L-word to telling him many, many times a day that I love him. He puts up with me and my mood swings, is happy to leave me alone when I need social recharge time, and is just really quite marvellous. He makes me laugh despite his cracker joke-level sense of humour, gives great hugs, and most importantly buys me Lego. For the first time in blummin’ yonks, I feel safe, and like I’ve come home.

“So happy new year, this is the one we talked about and
Happy New Year, this is where it all works out
This is where is comes together and everything comes through
Happy ever after all comes true”
-Simma, Happy New Year

So going into this new year, everything seems different. We’re moving into a new house together, and I really can’t wait. The cat and the hamster have double-barrelled surnames. I have a new job lined up, though it’s in the same centre and will involve moving a mere several metres across the office to a different desk. I still worry that it’ll all come crashing down at some point, but I’m managing to keep those thoughts in check and just enjoy it all for the most part.

Hopefully I’m not sounding too smug here. I just want you all to know about the good things that happen, since I tell you probably far too much about the bad stuff. I’ve had some amazing e-mails in the past from readers who have been through similar experiences to me, and I’d like you to know that things can change and can end up even being miles better than they ever were before.

I hope you all have a wonderful Christmas and New Year. I know this time of year can be really hard for some. I send my love and hugs to you.

The Prometheus Pants Problem Explained

Prometheus. It’s the film that disappointed pretty much everyone. The internet is flooded with in depth critiques of it, many of which refer to the lack of real science, along with the deep metaphysical and philosophical issues with it. All of these posts, however, have missed what I found to be the most problematic feature of the film: Underwear.

And yes, I know it came out two years ago, and it’s a bit weird to be writing a blog post about it now, but I’ve found myself trying to explain the Prometheus Pants Problem (PPP) to a few people, both verbally and on Twitter of late. Its complexity and importance means that 140 characters will just not do, and I think it is important to have a robust reference source to refer people to when explaining all aspects of the PPP.

It is important to note, I think, that in actual fact I vaguely enjoyed Prometheus. When I saw it at the cinema, I hadn’t seen any of the Alien films (I know, I know), but I thought it was worth a shot anyway. I found the running about with lots of alien goo stuff flying about fairly entertaining. The problems came when they kept interrupting the frivolous alien romp bits with Important Thinly Veiled Stuff About God, which made me rather lose patience. And, of course, I ended up pretty fixated on the PPP, which meant that I couldn’t think about anything else in the film. I’m like that- I’ll fixate myself on one tiny thing that happens for a millisecond, and then spend the entire rest of the film thinking and internally ranting about it.

1.       The Need for Pants At All.

Let’s be honest with ourselves here. You get in from a hard day’s work. You’re not expecting anyone. You’ve got a whole night of delicious nothingness stretching ahead of you. Its toasty warm in your home. What’s the first thing you do? You take off your uncomfortable outer wear, and let it all hang out, right? I mean, no one is going to see you and you’re in the comfort of your own home, so why the hell not wander around in all of your naked birthday suited glory if you want to?

Perhaps you wear your PJs instead, or a pair of comfy pants. That’s probably because, deep down, you’re sort of somehow worried that someone might see. You might get an unexpected visitor, or the pizza man might be arriving at any point. But imagine for a second that you are the only person alive at that point in time. What’s the point in clothes then? Especially if you can absolutely, categorically be sure that you’re the only one, because you’re the person who creates lifein the first place, and you haven’t yet drank the wormy goo that you need in order to do so yet.

So, in the opening seconds of Prometheus, we’ve got our engineer guy, on a planet in which he hasn’t yet created life (except for, well, all the plant life that is already there, but I think we’re supposed to ignore that). Now, never mind your front room, imagine having an entire planet all to yourself. Would you wear pants? Of course you wouldn’t. Any sane person would be running about joyfully, jiggling here there and everywhere, enjoying the sense of freedom. You’d let every little bit hang and flop about as much as you like, because who is going to be there to judge?

2.       The Need For Pants At All Part 2.

We don’t ever see any Female Engineers at any point in Prometheus. Thanks for that bit of everyday sexism, Ridley. The Baldy One does not seem to require any sort of sexual act to create life: just a shot of tarry goo, and that’s that.

 So on this basis, would they even have genitals at all? And even if they did, why would they be considered a special part that needs to be nestled away from prying eyes, if the reproductive act doesn’t need to take place? 

3.       Disappointing Pant Technology

Let’s play devil’s advocate here for a while and accept that pants are required for some unknown reason. This then leads on to another problematic issue.

These engineer types appear to be pretty smart. After all, they are the purported creators of life itself, right? Yet with all of their super advanced technology and supremely high IQs, the best they can come up with is a couple of bandages wrapped around themselves, nappy-like.

That just doesn’t ring true to me. Even our lowly human selves can come up with better pant technology than that. We have all sorts of colours, fabrics, designs, access holes, fastenings, elastic etc. But no, this superior life form instead decides to wrap some bandages around its crotch. How much of a faff must those things be to get into? They’d be a right clart on to get back out of if you need a wee. Do they need someone else to help them put them on in the morning, holding the bandages while they spin themselves around? How undignified and inconvenient.

4.       Lack of Pant Technology Evolution

This first engineer scene is Prometheus presumably takes place thousands of years prior to all of the kerfuffle depicted in the rest of the film. And yet, we are supposed to believe that pant technology has remained starkly primitive through all of this time?

The evidence for this is Noomi, who is merrily wandering around, post-surgery, wearing what is clearly another pair of low tech bandage pants, along with a matching bra. What’s happened to underwire technology? Why are people from this time still wearing the same design of crap pants as their creators? Surely, in the intervening millennia, someone would have realised elastic exists.

And that, dear friends, is a brief examination of the Prometheus Pants Problem. I’ve seen it creeping into other films since (most recently Guardians of the Galaxy), and I won’t rest until these important questions are answered, in full.

Other things to note about Prometheus:
-They appear to use Joseph Joseph kitchen implements. Nice to know that this mid-range kitchenware design brand is still going strong that fair into the future.

-Wandering around important historic sites that have been sealed off for thousands of years should probably be done in a more respectful way, if you’re wanting to preserve it for proper research. One guy says at some point “We’ve changed the atmosphere in here”. Well, yes, yes you have, though its nowt to do with the inherent evilness of mankind, and everything to do with barging in, blithely breathing your modern germs all over everything. If a door has been shut for thousands of years, I’d imagine that yes, it might get a little musty in there. Opening the door and allowing a bit of fresh air in is likely to change the atmosphere somewhat.

-The Dead Head that explodes: Apparently the theory behind this is that this head, reawakened after a very long time, can’t cope with how crap, evil and corrupt the world now is so it explodes. Now, I’m no expert in these matters, but I’m pretty sure that exposing a thousand year old corpse to all sorts of new atmospheres might well lead to a build up of some gases, which on electrocution, may well then explode.

-The most obvious plot hole of them all, which has most probably been covered in great detail elsewhere, still annoys me. Noomi’s oxygen is about to run out, and its all very tense indeed, but then phew, she is okay. However, it appear to magically recharge itself somehow whilst she tends to her errant offspring, as when she needs it again afterwards the oxygen level in there is just fine. Grrr.

Anyway, I’ll shut up for now, though I won’t apologise for bringing this important matter to your attention. And yes, you will now be forever destined to notice intently all pants being worn in any sci-fi movie, and yes, it will probably ruin all enjoyment for you. You’re welcome :D

Advert Annoyances Vol 1: Senokot

Welcome to the first installment in what is likely to be a very sporadic series. As you've probably guessed by now, I have a tendency to be irrationally annoyed by small things, especially when it comes to medicines. Adverts for OTC meds can be a prolific  source of cringes. Even leaving aside the requests for "you know, that one on the telly, where there is a guy and a dog and its a blue box", there will occasionally be a little phrase or image used in these adverts that makes me stop and seethe a little.

The current one at the moment, is Senokot. I can't find a link to the new advert, but when I do, I shall pop it in here so you can see for yourself.

There's all sorts of naturalistic fallacies going on, but that's not what annoys me the most. It's the phrase " works in harmony with your body" that i'm finding hard to stomach (geddit?)

Put simply, senna works by irritating your bowel. Your bowel notices that it is being hurt by something, therefore starts contracting and producing secretions to hastily get rid of the thing hurting it.  This then might make you poo, but from your bowel's point of view that's a side issue- its just trying to protect itself from harm.

That doesn't really sound to me like "working in harmony". You might as well say that fire works in harmony with human skin to make you walk faster- in actual fact, one is just out to hurt the other, meaning something else happens as an unintended- but sometimes useful- consequence.

it's Thyme to Bronchostop this nonsense

I’m sorry, I just could not resist that headline.

Whilst working a locum shift the other week, I noticed a couple of new products had leapt their way to the pharmacy shelves. “Bronchostop”. Sounds interesting, I thought, until I moved a bit closer and noticed that they are, in actual fact, a herbal cough remedy, and my vague excitement was replaced with a bit of my soul dying. Then I saw the price tag, and the anger kicked in.

Brought to us by our old friends at Omega Pharma, Bronchostop syrup contains thyme extract and marshmallow root, whilst the lozenges just contain thyme extract. Omega claim that it “relieves any type of cough”, and that it “takes the hassle out of choosing a solution”. Well, I must say, I’m pleased to hear that, because I find one of the main stressors in my life is choosing which cough remedy to use. I mean, it’s just so complicated to decide if you have a dry or a chesty cough, then realise that it makes no difference anyway as most cough medicines don't work, so you then just by a cheapo honey and lemon thing to make yourself feel placebo-ey better. 

So, given that the great all-consuming cough medicine dilemma of my life has now been sorted out by Omega, I can spend some quality time looking up the evidence to see if it works.

It turns out that there are some preliminary trials which suggest thyme might improve cough symptoms. However, these all use specific cough syrups with different combinations of ingredients compared to Bronchostop, so they’re not very helpful. Because the product is being sold as a traditional herbal remedy, the manufacturers don’t need to bother collecting any evidence that it works before it goes on sale- their claims are based entirely on “traditional use”, which means nothing at all scientifically.

One attempt at a clinical trial compared thyme syrup with a “real” expectorant, bromhexine, and found no difference over a five day period. There are a number of problems with this though- firstly, bromhexine isn’t commonly used in cough medicines. Secondly, there’s little to no good evidence that expectorants work anyway, so we’re comparing something that may or may not work with something that doesn’t.

Worryingly, the websitewww.bronchostop.co.uk contains absolutely no safety information whatsoever. It doesn’t tell you who can’t use it, who needs to be careful using it, or what any of the side effects might be.

What side effects could it possibly have, you’re wondering. After all, its just a herb. We eat it, so it can’t be that bad, right? Well, sort of. The amounts used in food tend to be a lot lower than when it is used as a herbal medicine.

On the whole, thyme is well tolerated, but occasional gastrointestinal effects can occur. Uncommonly, and more seriously, people can have allergic reactions to it. It can interact with drugs, including those that thin the blood, those used in Parkinson’s disease, those with anticholinergic or cholinergic effects, oestrogens (research suggests it may decrease the effects of HRT, but theoretically also the contraceptive pill), and non-steroidal anti-inflammatory drugs. It may cause problems in people with bleeding disorders, who are undergoing surgery, or who have hormone sensitive cancers. We have no idea of the effects that medicinal amounts of thyme can have in pregnant or lactating women.

It seems to me, however, that its main adverse effect will be on your bank balance. This stuff is £8.99 for a 200ml bottle or £4.99 for 20 pastilles- that’s a whole lot more than simple linctus, which is about £1.50 and which will probably do just as good a job.

In memory of Rachel

I didn’t know Rachel at all. But I was told her story last night, and all of today I have been thinking about her. I don’t know how old she was, what her life was like, the colour of her hair, whether she spelt her name with just an 'e' or if there was an 'a' in there too. 

It sounded like Rachel was a nice person. It sounded like she was enthusiastic (I think she met the teller of her story whilst volunteering for something).

Rachel was diagnosed with bipolar disorder. She was encouraged to try homeopathic treatment for it, and to stop her conventional medicines.

Several days after stopping her medicines, Rachel took her own life.

Many of you might remember that I blogged about a homeopath’s response to my good friend’s request for help for her own bipolar disorder. At the time, I theorised that, had my friend followed this homeopath’s advice, she would have destabilised and it would have killed her. 

I’m so, so sad that this happened to Rachel. I often get questioned about why I do what I do, why I rant on about homeopathy and alternative medicine so much. If other people want to use it, I’m told, then just leave them be. But how can I sit back and not do anything, when there are other people out there just like Rachel? If I can make any difference at all, even a tiny one, then I will do. If I can make even just a couple of people raise their eyebrows and wonder why homeopathy is still used in this day and age in place of effective treatments, then I’ll keep doing what I’m doing.

Sorry, Rachel. I’m really sorry that this happened to you. I didn’t know you, but I’m sorry that you went through all of that, and I’m sorry that your friends and family and the world lost you.

to study pharmacy, or not to study pharmacy?

I always wanted to be an archaeologist, growing up. I knew, however, that this was probably a pipedream- partly because I dislike creepy crawlies, but mostly because I was pretty sure in my childhood brain that everything interesting would have been dug up already by the time I was old enough to work.

Turns out I was wrong about that, but I’m still really proud of the profession I ended up in. I remember wandering up to the local shops with my Mum when I was little. We were talking vaguely about the future, when we had a little nose around the local chemist’s shop, cooing at the colourful bubblebaths and hairgrips that they had in stock.

“I know”, Mum said. “Why don’t you become a pharmacist?”

“What’s one of those?”, I asked. As far as I was concerned, the chemist’s shop was a place to buy cheap make-up and bath salts.

“Well, they stand in the back and mix up the medicines”. That’s it, I was hooked. I had images of brewing potions, mixing up gloopy ointments, and all sorts of stuff that, it turns out, in real life you only actually get to do for a couple of hours as an undergraduate. But my decision was made, and all the rest of my life I knew I was going to be a pharmacist.

As I got older, and I started telling people what I wanted to do, I used to hear nothing but positive things. I worked as a counter assistant in my local super market, and locums always used to tell me “You’ll never be out of work. Everyone is always desperate for pharmacists.”

At the time I graduated (2006), it still hadn’t been that long since the Great Pharmacist Shortage. This happened because the old style three year degree now became a four year Masters degree- so there was one year where no newly qualified pharmacists came on the scene. Everywhere you looked, people were crying out for a full time pharmacist to work for them. Whatever happened, you always knew that you could locum as a back up, and earn a good wage doing so.

As university went on, and I started applying for pre-reg places, I got worried. Not because I didn’t think I would get a place- in actual fact I was being courted by several companies, all of whom were clamouring to fill their pre-reg spots. I think I did maybe 10 interviews, and I got job offers from every one of them (and believe me, some of those interviews I was really quite atrocious in). No, I was worried, because I wanted to do my pre-reg in hospital, and I knew that pre-reg places really were limited in my local area- only 7 for the whole city.

I was lucky, and I got in. My year was really lucky, as it turns out there were enough jobs going for each of us pre-regs- though I actually went elsewhere. Whilst community pharmacy jobs were plentiful, hospital pharmacy was a lot more difficult to get a job in.

Nowadays, it has changed so much. I don’t think I can ever really hear myself saying the sort of things I was told to an enthusiastic school child now. “You’ll never be out of a job” would just simply be a massive lie.

When I was choosing universities, there were only a handful that actually offered pharmacy as a degree. In recent years there has been a proliferation of universities offering it now though, and as a result, the number of graduates is increasing year on year. I’m sure this isn’t the whole reason, but we have now reached a point where pre-registration places are becoming really hard to come by. There is a group of potential pharmacists, year on year, who will simply never be able to get a place anywhere.

So what does that mean? Well, you can’t register as a pharmacist, so you can’t work in your chosen profession. You’ve still got a Masters degree- but you’re actually pretty limited as to what you can do with it. Sure, its equivalent or better than a pharmacology degree, but you’ll always have a question hanging over your career, whatever you choose to do: “If you’ve got a pharmacy degree, why aren’t you a pharmacist?”. There’ll always be a slight, unfair, cloud of suspicion there. It means, even for those lucky enough to get pre-reg places, that jobs are more and ore difficult to come by, wages are being lowered despite responsibilities and workloads being higher, and locum shifts are both hard to get and pay an awful lot less.

Several places that I do locum shifts for have an email alert system for new shifts. On several occasions, I have received an email, checked my diary for my availability, then rang back immediately only to be told that all the shifts have gone already. The good thing that comes out of this is that, once you get your foot in the door, there is an incentive to work hard and become known as one of the best, most hardworking locums, because then you will get offered shifts first. The bad thing is that its now really hard to get that first step on the ladder.

How do we fix it? I have no idea, as it’s a multifactorial problem. A cap on the number of students studying pharmacy does seem logical, but that’s already been stamped upon by the Minister for Universities, science and cities Greg Clark MP, who has said:

Having considered the evidence I have decided that it is not necessary to introduce a specific student number control for pharmacy. The government's objectives for pharmacy can best be achieved outside of a number control system. It is the government's policy to remove student number controls wherever possible to enable students to have greater choice and to encourage universities to offer better quality courses to attract students. I believe pharmacy students can and should benefit from this reform and not be restricted. Therefore there is no need to consider further options for a pharmacy number control.”
It seems to me that the one thing that Mr Clark isn’t considering is those students. Yes, they might have greater choice, but I wonder, if asked, where their priorities lie- would they rather have more choice, or would they rather have some security in their future. I wonder if it has occurred to him to ask them directly.

So it is that I, and a number of other pharmacists, are sadly starting to discourage students from looking at pharmacy as a profession. Its through no fault of their own, and its brilliant that so many young people want to be pharmacists- but its hard out there, and its only going to get harder. Our bright young potential pharmacists might be better off opting for a less focused, vocational degree.

Coldzyme: a result of real science being left out in the cold

There’s no getting away from it, folks. Its sniffle season. For the next 6 months or so, the sounds of sneezes, coughs, and millions of noses being blown will echo throughout the nation.

We all know by now that the common cold is a virus. We all know that there is no cure. We also all know that, although you feel like crawling into a small dark warm cave and dying at the time, its usually much better after a few days, and it goes away of its own accord. Cold and flu remedies do nothing to actually get rid of your cold- they are there to make you feel better during it, although many of them are actually irrational combinations of products in shiny boxes with a redonkulously high price.

It is often said that if someone did come up with a cure for the common cold, they would be millionaires. I was, therefore, surprised to read this week in Chemist + Druggist magazine that indeed, the first ever product to not only treat the symptoms but to act on the virus itself was winging its way to pharmacy shelves as we speak. Really? Because blimey charlie, if that's the case, then this product should be Big News. 

Image source: http://www.sourcewire.com/news/84612/by-cod-now-your-plate-of-fish-chips-could-stop

The product is ColdZyme, a mouth spray that costs £8.99 for 20mLs. Seems a pretty fair price to pay for a product which claims to cure the most prominent infectious disease in the western hemisphere. It seems odd, though, that instead of this marvellous scientific breakthrough being plastered all over the media and medical literature, the article announcing it is tucked away quietly in a barely read corner of a trade journal.

What is this breakthrough, miracle product that will powerfully break down viruses? Well, an enzyme called trypsin. An enzyme that already merrily and plentifully kicks about in your digestive system, breaking down proteins. An enzyme which, for the purposes of this product, is inexplicable being derived from cod (which has meant that I have had to resist the urge to refer to it as somewhat fishy.) An enzyme which should be stored at temperatures of between -20 and -80 degrees Celsius, to prevent autolysis. Now, I've seen some fancy medicine packaging in my time, but never a simple mouth spray bottle that can manage such cold chain storage feats. So, if trypsin really is present in this product, then it seems fairly likely that its going to be inactive, unless the manufacturers have found a way of warping room temperature. Or you happen to be in Winnipeg in the middle of winter.

Medicine vs. Medical Device
The manufacturers make some really very extraordinary claims on their website, including one textbook example of special pleading. Their product, they state, isn’t a medicine. It’s a medical device, because it has no systemic effect. They then of course go on to helpfully tell us about the systemic effect it has:

“The medicines currently on the market only treat the various symptoms of a cold. ColdZyme treats the cause of the symptoms – the virus itself – and thus works both preventively against the common cold and shortens the duration of illness if you have already been infected.”

Right. So in the same breath, they are claiming that the product only forms a barrier, no more. But then they are also claiming that this barrier affects the ability of the virus to produce illness if you are already infected- viruses which are already through that barrier and inside your body. Come on, Enzymatica, you can’t have it both ways.

The Evidence
All these claims are backed up by evidence, right? Well, there is a tiny trial performed on only 46 people, which isn’t published anywhere. I can’t say whether or not it is a well designed trial, because I can’t see it in full, so to be honest, we pretty much have to just discount it. What we can do, however, if have a look to see if there is any other decent published information looking at the effect of trypsin on the cold virus. So I turned to the medical databases Medline and Embase, to trawl through the published medical literature. 

I did find one experiment which looked at the trypsin sensitivity of several human rhinovirus serotypes(1). And this appears to have found that viruses are only really susceptible to trypsin when there have been exposed to low pH, followed by neutralization- something which wont have happened to your common or garden cold viruses. I couldn’t find much else suggestive of a clinically significant antivirus action of trypsin.

The practicalities
This isn’t a simple, one-off- couple of sprays and away flies your cold sort of product. You have to use it every two hours, as well as after you brush your teeth and before you go to bed, and you have to continue this “until your symptoms are relieved”. That’s one hell of a regime. I have difficulty remembering to use medicines twice daily, never mind every two hours. I’ve never used this product, but I’d imagine that if it really does leave a “barrier” coating in your mouth, its a pretty unpleasant sensation. I can’t imagine many people sticking closely to these dosage instructions, and if the mechanism of action is as the manufacturer’s claim, skipping doses would cause the product to fail (if, indeed, it works in the first place)

We are also directed to “Start using ColdZyme® as soon as possible when you detect symptoms of a cold.”. Now, those of use who suffer with cold sores who have ever used aciclovir cream will know that this is often easier said than done- you probably haven’t got the stuff in the house, or at work, and by the time you’ve managed to get your hands on some, its already too late- your cold sore is out loud and proud, and using the drug will be pointless. Its likely that the very same thing will apply here. And remember that the incubation period for a cold is about 2 days- so the virus will already be cosily settled into your body before you even know about it. Its therefore completely ludicrous that this product claims to be able to reduce the length of a cold simply by forming a barrier.  

I know it can be used as a cold preventative, but how many people who feel completely fine are going to remember to use the product every two hours, every day, for the entirely of the cold season?

To Summarise
So, do I think there is scientific evidence to back up the extraordinary claims being made by ColdZyme? I might do when hell freezes over. Or at least when some decent trials are published, which might take just as long.  Do I think that this product should be sold through pharmacies? Absolutely not- this isn’t, if you ask me, real medicine. This is pure pseudoscience, trying its best to fool you into buying real medicine. Do I think lots of people will buy this, use it once or twice, then leave it to languish in their bathroom cabinet? Absolutely.

Here’s the problem though: this stuff will appear on the shelves of pharmacies all over. The pharmacists wont have a clue what this stuff is, and because they are really busy and probably quite tired at the end of each day, they wont be able to do the sort of evidence review I have managed to squeeze into a quiet moment. So they’ll get asked about it, and they’ll sell it. Some people will buy it and will feel better after a few days, and will think that the spray has made them better, forgetting that colds are self-limiting anyway. A customer might come back in the pharmacy one day, and say something like “hey, that new-fangled spray got rid of my cold!”, and the pharmacy staff will end up making recommendations on the basis of customer feedback and anecdotes, rather than on the basis of rational, scientific evidence. In my eyes, this really is a shame, and by selling this sort of nonsense, we really are cheapening our profession, and we're causing our customers to waste their money. 

If patients ask me about it, when I’m working behind the counter, I’ll tell them something along the lines of: “there’s no evidence or logical way that it works. It seems to be a bit of an expensive gimmick, with no decent basis to it. You’ll feel horrible with your cold, but it will start to go away of its own accord, I promise. In the meantime, you’d be much better off looking after yourself, having plenty of fluids and rest, and taking paracetamol according to the packet.”
