Horrible Times 1

2 Comments

Over the last weekend I started writing what I hope may become an occasional series of comment/diary entries emanating from the current mess known as Coronavirus. Here’s what I wrote on Sunday (lightly edited).

Sunday 15 March 2020 – Ides of March

This Coronavirus (Covid-19) is getting a grip of everyone. It looks like we’re in for a long haul, and a very messy one. Few of us trust the government’s strategy, which is at total odds with what the rest of the world are doing (except for the USA, and President Trump is an even bigger moron that Boris Johnson). The strategy may protect the over-70s for a bit, meanwhile it will rip through the rest of the population. Then the over-70s will succumb as soon as the restrictions come off, creating a second (and third etc.) wave before we’re near to having any treatment or vaccination options – don’t expect those within a year. Anyway it is now much too late; the genii is out of the bottle and in my estimation has been since probably mid-December (because the first case is now thought to have been in mid-November, but not recognised for what it was). So we needed to impose draconian social distancing measures very early, like back at New Year, if we really were to nip this in the bud.

I’ve already cancelled one of our doctor’s patient group events for this week, and my meeting the same morning with the Practice Manager. More will doubtless follow over the next few days. Others organising events I’m involved with as far ahead as mid-May are discussing cancelling them too.

Unfortunately I’m also minded to cancel my fortnightly massage sessions: not only because it’s a risk to me but also because my masseuse is newly pregnant and others working in the same practice are at significantly high risk. That makes me really sad as I enjoy the massage sessions and the chat, and it does help keep my back going. But we need to consider others in this as well as ourselves.

Amongst all this I’m really frightened and depressed. I’m almost 70 and with diabetes, obesity and sleep apnoea so I’m in a high risk category for serious complications if I do get Covid-19. And if I do I fear that it will kill me – either because my immune system is too compromised or because the hospitals won’t be able to cope and I’ll be a low priority for treatment.

I know the chances of me succumbing to this are relatively small, but that doesn’t make it any less frightening. So I feel my best hope is not to get this and be around long enough for either a good treatment or a vaccine.

But then I’m worried too that Noreen will fall ill. She’s not far behind me in age and she does have a long-term hereditary condition, although that doesn’t seem to affect either her immune system or lungs. Indeed her immune system, hitherto, has been so good it keeps many things under: she’s a Typhoid Mary. If Noreen does fall off her perch before me I know I shall be absolutely sunk: not because I can’t do what has to be done (although that may not be easy) but mentally; the depression will be completely overwhelming. Equally I know Noreen will struggle without me.

But what can we do? Both of us being risk averse as we are we’re inclined to behave as if we’re over 70, and self-isolate as much as we possibly can. Luckily we can (for now, at least) get grocery deliveries – not ideal but OK – and we have the reserves we built up against Brexit to help.

Even before all this I was beginning to feel my mortality and realising that I likely have only a few more years. The thought of not being here leaves me feeling deeply sad and almost terminally helpless. I’m starting to understand how, in his last years, my father just gave up the will to keep going.

It’s also interesting to start to really appreciate how frightening in must have been for people during the Black Death of 1348-9, the Plague of 1665, and the Spanish Flu of 1918-19; especially given that they really didn’t understand how any of this worked and what they could do to mitigate the diseases. In that sense at least we stand half a chance.

Please stay safe everyone!

Sex is Binary

About three weeks ago there was an article in Wall Street Journal [paywall] under the headline:

The Dangerous Denial of Sex

The first half of the article crystallised what I’ve been thinking for a while: that although there are rare instances of intersex individuals, to insist that biological sex is a spectrum is erroneous. Supplanting biological sex with a subjective and fluid “gender identity” arrived at “by the whim of the owner” (my deliberately slightly irreverent words) is unrealistic and impractical. To quote just one paragraph of the article:

There is a difference … between the statements that there are only two sexes (true) and that everyone can be neatly categorized as either male or female (false). The existence of only two sexes does not mean sex is never ambiguous. But intersex individuals are extremely rare, and they are neither a third sex nor proof that sex is a “spectrum” or a “social construct”. Not everyone needs to be discretely assignable to one or the other sex in order for biological sex to be functionally binary.

From here on I dislike the tone of the article which to me sounds very right-wing, misogynistic and derogatory. Added to which I’m far from convinced the authors’ arguments follow logically.

That is not to deny (a) that some individuals’ biological sex is ambiguous, nor (b) that some individuals may self-identify to a different gender than their biological sex. While I will admit to not fully understanding this (cis-hetero male privilege and all that), it seems to me that the disconnect between an individual’s biological sex and their gender identity begins in some way as a psychological process. My gut feeling is that the medicalisation of this to sex reassignment is not sufficiently controlled or counselled (especially in adolescents), and is thus somewhat dangerous – as the quoted article goes on to imply.

This is also not to deny the psychological stresses that those affected go through in coming to terms with their situation, leading up to gender-reassignment, and that they encounter during transition – this latter is something I’ve witnessed in a work context and which was quite disconcerting even to a completely uninvolved bystander.

So basically I’d say: by all means gender identify however you please, but in the vast majority (not all) of cases biological (anatomical) sex is binary, not a social construct. Yes, gender reassignment surgery is possible, and some require it. However it is not something I’m personally comfortable with – just as I’m not comfortable with IVF etc.

As with so many other things, while I may not agree with you or be comfortable with your views, I would defend and support anyone’s right to gender identify however they wish. It’s your life, not mine.

Of course, YMMV.

Coronavirus: Attitudes to Panic

This post has originated in all the fuss surrounding the Coronavirus situation. In it I’m not interested in the science of how the Coronavirus works, or how it is being treated. I’m more interested in our reactions and the way we (individually and collectively) are approaching the problem.

The post is constructed around quotes from four comment articles [1-4] (referenced below) which have appeared in the last few days.

What’s interesting to me, from a rational standpoint, is the psychology and attitudes behind what is happening.

In the new coronavirus, we see a world that is more connected than ever by international travel, but that has also succumbed to growing isolationism and xenophobia. We see a time when scientific research and the demand for news, the spread of misinformation and the spread of a virus, all happen at a relentless, blistering pace. [4]

For example: The number of people travelling by plane every year has more than doubled since SARS first emerged, in 2003 [4] and we now have 24 hour rolling news both online and on TV.

On top of that

People are often optimistic about risks [called] “optimism bias”; people may think they can control their own exposure to diseases, that they don’t need a vaccine because they aren’t susceptible to flu, or that they won’t transmit their cold to others. [1]

It’s entirely normal that there are still many uncertainties [4]. We don’t yet know enough to be completely certain about the risks of COVID-19 … no one really knows how bad COVID-19 is, and how much damage it could eventually lead to [3].

For instance: How transmissible is the virus? Once infected, how much time passes before people show symptoms, and how likely are they to die? Which people are most at risk? [4].

It appears that on average, infected people spread the virus to two or three others [4]. This the Basic Reproduction Number (what epidemiologists call R0). It is about the same as that for flu, but way lower than for measles which has an R0 of 12-18 [5].

Current data suggests that COVID-19 kills around 2% (the Case Fatality Rate) of those infected [3] (although expect this number to change). However flu with a Case Fatality Rate of 0.1% kills more people [3] (presumably because although it is more widespread, we have a vaccine).

Even the normally cautious epidemiologists don’t know the answers. Harvard epidemiology professor Marc Lipsitch [says] “I think the likely outcome is that it will ultimately not be containable” [2].

In fact

Lipsitch predicts that within the coming year, some 40 to 70 percent of people around the world will be infected with the virus that causes COVID-19. But … this does not mean that all will have severe illnesses. “It’s likely that many will have mild disease, or may be asymptomatic”. [2]

That doesn’t sound good, so no wonder the uncertainties that academics are used to dealing with, about fatality rates or transmissibility, are stoking fear [4] because when we’re uncertain about something, we often rely upon our feelings and prior experiences in place of information. Surgical face masks offer the sense, however illusory, of protection [1].

Indeed

According to experts, the value of surgical masks depends entirely on the context in which they’re used: a surgical mask won’t work unless it’s worn consistently and properly. If worn incorrectly, their utility quickly plummets … Though face masks may provide the feeling of security, masks are most valuable in situations where they are necessary – such as among front-line health workers … We touch our faces, noses and eyes many times a day, making it difficult to completely avoid contact with infection. [1]

[If you want more on face-mask efficacy, see my post “Coronavirus and Face Masks” of a few days ago.]

While

researchers can share data and refine ideas faster than ever … they’re doing so in full view of a concerned citizenry … [and] … preliminary data that might once have run the gantlet of peer review before being published can now be downloaded by anyone, sparking misinterpretations and conspiracy theories. [4]

A climate of uncertainty can cause misinformation to flourish [1] and create fertile ground for mixed messages and inconsistency, which in itself can breed mistrust and fear [3]. And as we all know false reports readily cascade through channels that amplify extreme messages over accurate ones … Hoaxes and half-truths are huge problems during epidemics [4].

But of course we’re often required to make decisions based on having incomplete information [3]. I would actually go further: we never have all the information we need to make the decision; all we can do is to make the best decision we can at the time with the (limited) information we have.

This is why clear messaging from trusted sources, and guidance on what to do and how to do it, is essential during a pandemic [1]. Especially communicate often, communicate what is and isn’t known clearly, and provide simple action items for individuals to take … like hand-washing [and] acknowledge that [all of this] may change quickly [3].

However with public health that’s not easy. The risks of sending the “wrong” message can have devastating consequences – unnecessary anxiety on the one hand … and thousands of unnecessary deaths on the other [3]. And confused citizens might forgo sensible measures such as hand washing in favour of inefficient ones like panicked mask buying [4].

What’s perhaps worse is that border screenings and travel bans have historically proved ineffective and inefficient at controlling diseases. If anything, they can make matters worse. People will find a way to get where they want to go [4]. For example, although the Iran/Afghanistan border has been closed, some 3000 people cross that border illegally every day [6].

What’s more

bans can also break the fragile bonds of international trust … If countries know that they’ll be cut off during an epidemic … they may be less likely to report future outbreaks, leading to costly delays. [4]
Waiting too long to sound the alarm can be disastrous. [3]

As with many things this leaves us with a spectrum of possible reaction and attitude.

On the rational end, we must ask ourselves about … the effectiveness of [any] solution … [and how individuals can use that] solution effectively. On the emotional end, we ask ourselves about … how severe might it be if we … were infected [and] how likely we might contract it. [3]

A lot of the expert discussion (or at least discussion quoting experts) in the media has been at the rational end about the effectiveness of various actions, while I suspect a majority of individuals are inclined to work more towards the emotional end of the spectrum – often because they’re not presented with clear, concise, factual information; whether deliberately by the less reputable press and politicians, by omission, or because it is just packaged in a way they can’t understand.

At the end of the day we probably have to move individuals quite a long way (probably further than is possible) towards the rational side, while at the same time ensuring that the experts are doing as much as possible to make the right solutions effective and have some understanding to allow them to meet the individuals part way. That’s probably a circle that can never be made fully square. Nevertheless the experts have to work their socks off to square the circle as best they can, and take the people with them in supporting their solutions. And that ain’t ever going to be easy.

Coronavirus and Face Masks

1 Comment

What follows is from a senior A&E Consultant with whom I am very slightly acquainted. It is based on the latest information on various NHS websites, and is reproduced with permission.

IMPORTANT: A public service announcement about face masks and coronavirus

Dr Rowley Cottingham, senior A&E consultant, Brighton & Sussex University Hospitals NHS Trust

Dated 16 February 2020, but still current on 23 February 2020

There is a lot of nonsense and misinformation doing the rounds about Coronavirus Covid-19. I have access to internal NHS briefings, and here is what is known to work at present:

Firstly, please don’t rely on the type of mask you see everyone wearing. They are entirely ineffective at stopping virus movements; you need one classified as FFP3 (Filtering Face Piece level 3) and to have undergone a ‘fit’ test to ensure it fits you. Even then the protection is relatively short-lived. Why do we surgeons wear simple masks while operating? Really just to stop bits of dribble, breakfast and similar falling in patients’ wounds.

The slightly better news is that unless someone pretty much sneezes ON you, you are unlikely to get a big enough viral load on your mucous membranes to start infection by breathing. Not impossible, but you need to play the odds. So if you think you may have CV that’s when you wear the simple mask – to reduce how much you shed.

Current internal NHS documents are saying that Covid-19 lasts about 48 hours on surfaces. Therefore, you are best off reducing the viral load on your hands as much as possible. Here are the rules, and I encourage you to adopt these from now for ever, as they are what will protect you from all sorts of infections, including things like norovirus, influenza, hepatitis A and many others:

  • Always carry tissues and use them to catch coughs or sneezes. Then bin the tissue, and wash your hands, or use a sanitiser gel.
  • Wash your hands often and thoroughly with soap and water, especially after using public transport.
  • Try to avoid touching handles – turn the tap off with your elbow if it isn’t proximity triggered and if there is a towel hold the door handle with it to exit before discarding it.
  • Avoid touching your eyes, nose and mouth with unwashed hands.
  • Avoid close contact with people who are unwell.

Covid-19 is a new strain of Coronavirus and we are still learning about it. There is an incubation period of up to 14 days, which is why those self-isolating are asked to do so for that period. We don’t yet know precisely when someone who has the virus is and isn’t infectious, which is why people are asked to self-isolate to prevent the spread of infection.

Monthly Links

Welcome to thee first of our monthly links for 2020. Here are links to items you may have missed the first time round, but will be glad you’ve now found. We’ve collected a huge number of items this month, so lets get stuck in …

Science, Technology, Natural World

You may well poo-poo astrology (and who should blame you!) but there is an argument that it paved the way for predictive, analytical science.

In the western world we do a lot to mask our body odour. Here’s some of the chemistry behind what we’re trying to mask.

Science’s theoretical models can be complex, however the most successful ones usually aren’t. [££££]

So how is it that some trees life 1000 years, apparently healthily?

Health, Medicine

I know my body temperature is naturally low, but it now seems that human body temperature is generally cooling over time. Two looks at this from New Scientist [££££] and Scientific American [££££]

Six curious facts about our sense of smell.

The whole situation around the new Chinese Coronavirus is moving so fast I’m not going there with blog posts. However here is something about the viruses which cause colds and flu.

While mentioning flu, researchers are now discovering that injecting the flu vaccine into a tumour stimulates the immune system to attack it.

Medics are coming to the opinion that many mental health conditions, from depression to dementia, are caused by inflammation.

The vaginal, uterine, cervical, clitoral, urinary, rectal, and muscular dimensions of the pelvis: the VAGGINA hypothesis.

Which takes us nicely on to …

Sexuality

Apparently almost half of British women have poor sexual health, around three times the rate for men.

Here’s something I didn’t know … One part of this is poor sexual health is that some women have incredibly painful orgasms. It’s not clear if this also affects men.

But men do have sexual problems too: it is thought that around 10% of men have Peyronie’s disease, which causes significant bending of the penis; it’s often painful and prevents sex.

One woman talks about how wanking brought her closer to her husband. [NSFW]

Environment

One UK scientist is suggesting that half the country’s farmland should be transformed into woodlands and natural habitat to fight the climate crisis and restore wildlife.

Following in the footsteps of the Woodland Trust, the National Trust to plant 20 million trees in the UK over the next decade as part of efforts to achieve net zero emissions by 2030.

It’s reported that London’s new year fireworks increased air pollution with a legacy of metal particles. Why is anyone surprised?

York is the latest city (following Bristol and Birmingham) to plan on banning private car journeys from the city centre.

I’ve been saying this for twenty years: the majority of business air travel is unnecessary; there are more environmentally, financially and employee friendly ways of doing business – and they’re just as effective. Why is there no will to grasp this?

Social Sciences, Business, Law

Hansard is the official record of business in the UK’s parliament. Here’s something on how their reporters handle getting to grips with an influx of new MPs.

Art, Literature, Language

OK, so who understands what sodomy actually is, at least according to the medieval world view. [LONG READ]

An Italian art gallery has discovered its stolen Gustav Klimt painting in a wall.

History, Archaeology, Anthropology

Archaeologists have found the graves of high-status Romans in Somerset.

Here’s a series of long reads from Going Medieval about medieval life …

The most maligned of creatures, since ancient times, the wolf has a central role in mythology. [LONG READ]

Medieval people were nicer to cows than we are now. [LONG READ]

Medieval courtly love was just as full of pick-up artists as other times. [LONG READ]

There’s a subset of society who (erroneously) believe the medieval Church was a shadowy organisation dedicated solely to suppressing knowledge and scientific advancement. [LONG READ]

No medieval people weren’t dirty. Yes, mediaval people bathed – a lot more than we think. They even invented soap! [LONG READ]

It’s interesting what you can find in the sludge of a London medieval cesspit.

Slightly nearer our own time, it seems that Columbus may well have been right in his claims of cannibals in the Caribbean.

Lifestyle, Personal Development

A Utah (think Salt Lake City and Mormons) court convicts a mother of lewd behaviour for bearing her breasts in front of her children. But is being naked around your own kids good for them? Spoiler: yes.

The “power of bad” and the “curse of good”. We’re living in a gilded age but can we defeat negativity?

There is some surprising psychology behind being perpetually late.

Shock, Horror, Humour, Wow!

And finally, the United Kingdom wins a Darwin Award for Brexit. Well who would have guessed?!
