Why?

No, OK, I do understand why. But it is a real pain …
Yesterday morning I had my ‘flu jab. I do this every year as (a) I’m now over 65 and (b) I have diabetes so I’m considered to be at “high risk”.
By mid-afternoon yesterday I was feeling rough. Last night I might as well have had ‘flu, I felt so awful — and I was so hot you could have fried an egg on me. (What a nasty idea!) I felt marginally better this morning and luckily I’ve gradually been improving as today has gone on.
Every year follows a similar pattern. 10+ years ago when I first started having ‘flu jabs they would make me feel rough for maybe half a day; on one classic occasion I felt awful for just one hour.
However a few years ago, when the vaccine contained “bird ‘flu” it knocked me out for over a week. Each year since then the vaccination has affected me for at least two full days, usually starting about24 hours after the injection. Consequently I scheduled this year’s shot when I knew I had three four days clear afterwards. It’s just as well I did, although if it has knocked me down for little more than 24 hours this year that’s definitely progress.
Yes, I do understand why this happens. Although the vaccine cannot give you ‘flu (the constituent strains are either live but attenuated or are totally inactive) like all vaccines they stimulate the immune system into producing antibodies — that’s what they’re supposed to do. And it is this reaction of the immune system, which thinks the body is being attacked, which causes the “illness” side-effects. What’s curious is that not everyone get these side-effects; and of course there are a small number of people (eg. those who are allergic to eggs) who cannot have the vaccine (or have to have an expensively produced alternative).
While the side effects are not pleasant they generally only last a day or two, and for my money they are far better than having real ‘flu which could last 2 weeks even without complications.
It’s just a nuisance to have to go through this every year. However until a way is found to produce a reliable “one shot forever” ‘flu vaccine we are stuck with annual injections. The ‘flu viruses are so variable, and they mutate so quickly, that the vaccine has to be changed every year. The game is to pre-guess which strains are most likely to be active during ‘flu season — for the northern hemisphere this guess has to be taken in February for the following winter; that’s because of the time required to produce the vaccine. When the experts guess right the vaccine is maybe 75-80% effective; guess wrong (as happened last year because of a late mutation) and effectiveness may be down at around 10%.
So while having a ‘flu jab is an annual PITA, it is one which for me is worth it. Until we get a universal vaccination, that is.

Piloerection

Piloerection — more commonly known as goosebumps …
We all get goosebumps.
But I have recemtly found out two things about this common phenomenon — one is general and the other seemingly specific to me.


Firstly piloerection (hairs standing up) is interesting because it is a demonstration of evolution not happening. We are all familiar with the cat with its fur fluffed out and tail bushed, usually when confronted with an aggressor. We’re all also familiar with the robin, or pigeon, fluffed up in the winter against the cold. Both these are the original uses of what we still have as goosebumps.
The way this works is that the tiny muscles around the hair follicles (or equivalent for feathers) react to cold or to adrenalin (produced in response to fear, or excitement). In contracting these tiny muscles pull the hair into a more erect state and cause the little bumps around the hair follicle. Humans have lost (most of) their fur, but we’ve not lost the response mechanisms to cold or which stimulate production of adrenalin. So we still get goosebumps, although they apparently confer no advantage on us. There is no cost, the reactions aren’t deleterious, so there has been no evolutionary pressure to remove the reaction. This is one of a number of traits which (some of) us exhibit and which are evolutionary remnants; others include our tails, widom teeth and appendix.
Like everyone I get goosebumps, and the tingling sensation of the skin that usually goes along with them. And, also like most, this is strongest on the forearms. But what I’ve noticed recently is that this is more marked on the right side of my body than the left. Sometimes it is only on my right side. Sometimes both sides but the right predominates. Whether it has always been like this I don’t know, but I think it probably has. I find this strange and I can neither find, nor conjure up, a satisfactory explanation. Does anyone have any clues?

Boost for GP Services

NHS in £2.4bn funding boost for GP services in England says the BBC News headline.
So OK, our hard-pressed GPs are going to get a funding increase over the next four years which will pay for 5000 more GPs and the same number of other GP practice clinicians (nurses, pharmacists etc.). There will also be:
– a relaxation of rules to make it easier to renovate premises or build new ones
– a public campaign to encourage junior doctors to become GPs
– the recruitment of 500 doctors from abroad to boost numbers.
While any extra help for GPs is to be welcomed, this does beg lots of questions, including:

  • Is this actually new money, or is some other part of the NHS being salami-sliced to find the cash?
  • Where does the government think it is going to find 5000 new GPs in four years, especially if only 500 are coming from overseas? Remember, it takes 10 years to train a GP from scratch and at least 4 years if they are already finishing their basic medical training. Oh and we’ve been hearing this “5000 new GPs” for the last 2 years or more, so this isn’t new!
  • What good is a public campaign going to be to encourage junior doctors to become GPs? It isn’t the public who need convincing, but medical students.
  • It is all very fine relaxing the rules on renovating/building premises, but this doesn’t help unless there is the money to do the work … and there’s no sign of that! [Just as an example, my GP’s have had planning permission for a small extension for 2 years or more, but so far no funding.]
  • Yes, we need more GPs, but existing practices also need a general funding boost as they are struggling not just with workload but the ability to pay for all the things they have to do. [You want the phones answered quicker? That means extra reception staff and they have to be paid.]

So yes, good, but …

Many Years On …

A few days ago there was an article in the Guardian under the banner Why it’s time to dispel the myths about nuclear power.
Just a couple of snippets:

Chernobyl was a perfect storm, a damning tale of ineptitude leading to needless loss of life. It was also unequivocally the world’s worst nuclear accident. To many, it is also heralded as proof-positive that nuclear energy was inherently unsafe, a narrative adopted by many anti-nuclear groups … But perception and reality do not always neatly align; in the wake of the disaster, the UN Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) and others undertook a co-ordinated effort to follow up on health effects … Despite aggressive monitoring for three decades, there has been no significant increase in solid tumours or delayed health effects, even in the hundreds of thousands of minimally protected cleanup workers who helped purge the site after the accident. In the words of the 2008 UNSCEAR report: “There is no scientific evidence of increases in overall cancer incidence or mortality rates or in rates of non-malignant disorders that could be related to radiation exposure … The incidence of leukaemia in the general population, one of the main concerns owing to the shorter time expected between exposure and its occurrence compared with solid cancers, does not appear to be elevated”.
… … …
Unlike the accident in the Ukraine, events at Fukushima in March 2011 were not the result of ineptitude but rather a massive natural disaster in the form of a deadly 15-metre high tsunami** … While the world media fixated on the drama unfolding at the plant, it lost sight of the fact that around 16,000 had just been killed in a massive natural disaster. Despite the preponderance of breathless headlines since the reality is that five years later, radiobiological consequences of Fukushima are practically negligible — no one has died from the event, and is it extraordinarily unlikely that anyone will do so in future. The volume of radioactive leak from the site is so small as to be of no health concern; there is no detectable radiation from the accident in Fukushima grown-food, nor in fish caught off the coast.
… … …
It is important also to see these disasters in the wider context of energy production: when the Banqiao hydroelectric dam failed in China in 1975 it led to at least 171,000 deaths and displaced 11 million people … None of this is to denigrate the vital importance of such technologies, but rather to point out that every form of energy production has some inherent risk.

Do go and read the whole article.
** It is worth noting again that the containment at the Fukushima plant worked largely as designed. Excepting the natural disaster, the root cause failure appears to have been one of shortcomings in plant external safety design and process which would be just as likely with any major plant.

Oddity of the Week: Stoned Yoni

This from Weird Universe, 13 March 2016:

“Medical” marijuana will take on a new meaning soon if the Food and Drug Administration approves Foria Relief cannabis vaginal suppositories for relieving menstrual pain (from the California company Foria). Currently, the product is available only in California and Colorado, at $44 for a four-pack. The company claims the inserts are targeted to the pelvic nerve endings, but International Business Times, citing a gynecologist-blogger, noted that the only studies on the efficacy of Foria Relief were done on the uteruses of rats.
