1} I will like to add SGLT2 inhibitor to MFN WHICH SHOULD HELP HIM TO REDUCE WEIGHT,may help to reduce BP medication and reduce his cardiac risk

2} Statin may have aggrevated diabetes.I will try Pitavastatin which may be superior to Rosuva in Diabetic

Posted by pdg53[/QUOTE]

Hello pdg53:

1. SGLT2 Inhibitors were not one of the possible answers in our clinical case because my decision was for having 1 option for the traditional oral anti-diabetic drugs (sulphonylureas), another 1 option for the newer anti-diabetic drugs (DPP-4-Inhib.), and one option for not adding any other anti-diabetic drug. But we should be aware that there is no long-term randomised clinical trial evidence, that I am aware of, that SGLT2 Innhibitors are effective and safe in patients with no established cardiovascular event,  like this one presented here in our case discussion. See the recent EMPA-REG trial recently published in the NEJM that was done with patients with post acute coronary syndromes.

2. You reached the target, and made the right diagnosis! This case here presented is indeed one of Statin-induced worsening glycaemic control. Pitavastatin could be a right therapeutic option also. Our patient choosed the generic atorvastatin, in a lower dose, than the previous higher dose of rosuvastatin, and succeeded regarding his glycaemic control.

All Best,

Joey

Turns out that Dengvaxia is not available in the UK, so I'll just have to rely on good repellant practice.

And a small event this morning - my London 2012 Swatch watch, presented to all Gamesmakers - stopped!    It had run since before the event until now, and like Grandfather's Clock has stopped - almost - in time with the next great event.

I could get a new battery, but it's already had a new strap, so that would make it a bit of a Trigger's Broom (Only Fools and Horses reference!) so I'll retire it gracefully.

Thanks DuaneF.

Now, what my boss at the university was emphatic is what many are realizing, ie, doping is getting all around sports.

Getting back now to the Olympic games, Maybe (I just said maybe here...) all the major money involved in the players involved are with the responsibles for the so-called "Olympic Legacy" for each olympic country headquarters can be one of the at least "soft" laws against doping in those games, because when the laws are soft, people do what they want. I mean here the International Olympic Committee. 

As an example.....I live in one of the many traditional Rio de Janeiro neighborhoods, lots of sports clubs, beautiful sea and beaches, bars, hotels, restaurants, live music, samba, bossa nova, caipirinha, wealthy, midle class, and also lots of poor people - Copacabana, Ipanema, Flamengo, etc.......There will be no "Olympic Legacy" in these neighborhoods.

The cultural life of Rio de Janeiro lies close to its beaches, period..........The Olympic Village constructions in Rio are being made extremely far away from the sea, where the mayor has its main voters.....and after the Olympics, I do not believe the much wealthy voters of the mayor, or the poor people who would eventually live close to these places (do not believe so much.....) would prefer going there on week-ends or holidays instead of going to the beach. All this for the sake of Olympic Legacy......what a waste of my money, because completely and unnecessary, and very expensive new facilities, were constructed, when we already had excellent ones with previous recent international, even world multi-sport modalities championships, spread all over the city of Rio de Janeiro, and also Brazil! Was the International Olympic Committee blind to this reality?

But the Olympic show must go on, with their main artists, the athletes...And I sincerely hope that our Federal Operation&Task Force against corruption "Car Wash" scrutinizes the neediness for all these new constructions in Brazil, in the Rio 2016!

PS: Olympic countries Headquarters Legacy plus TV Broadcastings plus Nike, Coca-Cola Contractcts, doesn´t all look like FIFA´s recent systemic corruption scandal?

All Best,

Yes, this is Atrial Tachycardia with 2:1 block

There is 2 P waves and 1 upright T wave , the first P wave was in the refractory period and so could not generate a QRS, hence the ratio of Atrial rate to Ventricular rate is 2:1

In Response to Retire early - live longer?:[QUOTE]

   I was always a bit worried by the story that Boeing, the aircraft makers, found that  employees who retired at 55 lived on average until they  were 83 years old, but if they hung on until they were 65 they had only 18 months to live.   But I loved working, even full time,  somehow I had a good life/work balance and I went on until I was 67.      One keen anaesthetist does not a statistical sample make, but was I fated to a short retirement?     I'm still here two years later, so I've bucked that figure, but still?

It's always good to see one's prejudices confirmed, and a recent article has just done that for me.    Wu, Odden,  Fisher et al used the records of 3000 people in the US Health and Retirement Study and, to remove the potential bias of early retirement from illness, divided them into the sick and the well.  http://jech.bmj.com/content/early/2016/03/21/jech-2015-207097.short?g=w_jech_ahead_tab  About a third were in the self-reported sick group and to no one's surprise, slightly more of them died in the study period.  But of the well, those who were a year  older were 11%  LESS likely to die from any cause!   The good statisticians also allowed for socioeconomic status, lifestyle and "health confounders" (no, nor me neither) but the message is that retiring early is not good for one's health, and a moderately late one can let you live longer!

Hooray!   Fire up the Quattro and crack open the Bolly! I'm off hang gliding and bungie-jumping, 'coz I'm immortal!

At my practice we have set up a WhatsApp group for locum GPs in the area. When we require cover we msg the group and this has helped to fill quite a few sessions when required. Would other locum GPs/partners be interested in this system if it were set up for their own area? It would ideally include locum GPs and several local practices. I think WhatsApp is much quicker than emailing/phoning - plus there is a saving in reducing the use of locum agencies. What are your thoughts?

Motion­-Tracking MRI Peers Into The Left Atrium To Evaluate Stroke Risk

Posted in Stroke at Fri, 29 Apr 2016 12:26:20

A research team from Johns Hopkins University has discovered evidence that abnormal function of the left atrium may lead to an increase in stroke risk. As the study showed, the risk for stroke was not dependent on the presence of atrial fibrillation. The findings go against the universally accepted notion that irregular rhythm in the upper chambers of the heart during atrial fibrillation (AF) causes blood clots to form, eventually finding their way to the brain.

The study was motivated by the knowledge that the current reasoning for stroke doesn’t fit in with what clinicians see on a daily basis – not all individuals with atrial fibrillation have strokes and not all stroke victims have atrial fibrillation. So this means that people with abnormal function of the left atrium are at risk for stroke, not only those with AF. 

Lead author and cardiologist Dr. Hiroshi Ashikaga, PhD, and his team f used a 1.5 Tesla MRI scanner (Magnetom Avanta, Siemens Healthcare) with motion­tracking software called multimodality tissue­tracking (MTT) made by Toshiba to study the movement of the myocardium (cardiac muscle).

There are risk factors everywhere, in any activity and in none, but people seem to consider them inevitable when they are probabilties.      Prof Sanjay Sharma, a cardiologist at St George’s and the London Marathon's medical director  has pointed out that sudden death in those who take exercise is very rare, 1:50,000, and that in the entire history of the London Marathon there have been just 14 deaths.  As this year's event saw the one millionth runner cross the finishing line, those two figures match well.

 

But what is the morbiidity of the LM?   THis article deals with1981-2003: http://www.pponline.co.uk/encyc/london-marathon-what-we-know-about-the-incidence-of-injury-illness-and-death-in-the-london-marathon-881#

Ignoring those who 'merely' consulted the St.Johns Ambulance members in attendance, in 1981 eleven of 6418 runners were 'seen in hospital', 0.17%.    At that first Marathon, I think that most runners would have been well experienced and fit endurance runners.   But lo!   In 2003, 32,300 people took part and 58 people went to hospital.  0.18%!!!!!   So the carnard of poorly prepared runners pushing themselves beyond sensible levels is that, an unfounded rumour.

I'll leave someone else to go through all the years and work out the proportion who needed, or were deemed to need to be seen in A&E, and I'll leave the author, Dr.Dan Tunstall-Pedo to summarise:

Over 23 years, the risks were:

  • contact with St John: 1 in 6;
  • contact with a hospital accident and emergency department: 1 in 800;
  • hospital admission: 1 in 10,000;
  • death: 1 in 67,414 – a risk which is comparable to many daily activities.

I don't think this level of morbidity is commensurate with a Marathon being bad for your health.

CTA or IVUS – which is better?

CTA (computed tomography angiography) is currently the gold standard for evaluating myocardial bridging, because it‘s highly accurate. However, recent research has shown that CTA is not all-seeing and all-knowing. IVUS (intravascular ultrasound) may be the better choice.

The study included 64 patients with symptoms of ischemia who underwent both CTA and IVUS. CTA earned its gold star, but surprisingly missed the majority of septal branches and soft plaques that could potentially cause serious complications.

Aren't you sometimes  hesitating whether to choose CT or MRI?  The methodologies of these diagnostic methods don’t differ too greatly from each other: the patient lies down on the exam table and is moved along through the scanner’s opening, where layered images are then acquired and afterwards transferred to a computer. But the essence of the methods is different.
 
This article will attempt to highlight the differences between these two methods, so that you won’t have any doubts.
 

Re: Should UK junior doctors strike over new contract plans?

'Should' questions are always heavily loaded by ethical and other concerns and are not always amenable to ballot-type enquiry.  My own take is that, perversely, Mr Hunt might has 'won' in provoking this strike. 

To explain, I am a retired consultant physician and I don't think I would personally have considered striking over any of the concerns I encountered during my own working life but the world of medical careers has changed hugely and I don't criticise the juniors for doing now what I would not have done then.  (Whether a strike was the best strategy is another matter).  I'm sure that most of those striking now might have considered this action unthinkable at the time they entered undergraduate training so it must be a bitter defeat of their personal beliefs for Mr Hunt to have pushed them to strike. Personally,being made to abandon my principles would have been more galling than even his manipulation of data and conflating juniors' contracts with any 'weekend effect'.

I'm sorry to have to say that the juniors have been left exposed by the main body of the profession who could and should have spoken more clearly with one voice about the nonsensical behaviour by Mr Hunt.  In my personal opinion, the Royal Colleges have said too little too late.  The old excuse about not being seen to be 'political' is simply disingenuous, particularly when earlier attempts appear 'neutral' about the Health and Social Services Act was taken by Lansley to signify support!

The other excuse about contracts being purely a matter for the BMA as the Union are similarly unbelievable, Mr Hunt's own perverse claim that this is all about safety and a 'seven-day service' provided the Colleges every opportunity to mount a much earlier and more robust evidence-based counter attack on these grounds alone.

Hunt has started his longer campaign by going for the juniors;  I think the seniors, the nurses and other NHS workers will rue the day they didn't all stand together to tell the truth to power.

It does not looks like being an issue only related to so-called depression or to psychiatric compendiums.

Suicide should be looked at the domains also of philosophy, human rights, quality of life, and bioethics.

Doctors should have high standards and therefore should be in one of the very best positions to say how health matters should be handled. If they have little say then their practice would be commandeered by non-clinical personnel to the end of definite failure.

That must never happen and if it takes a strike to correct matters, then strike hard till the appropriate standard is set.

Hi Joey

I think Insulin Pump device is not a complex issue, I have reflected what is going on among the researches that I have come through, some patients are doing quite well with CSll according to the studies, in fact it depends on the personal experience of the patient and his or her physician

Still studies are carried to evaluate the problem of DKA and Hypoglycaemia which occur often with multiple insulin injections in comparison to Insulin pump

This device as well as all drugs circulating in the market, and some researches are commercialized, you can feel this through the pharmi-companies, but over all we are looking for the benefit of the patient

Recent paper which I have read :-  http://www.diabetologia-journal.org/files/Johnson.pdf

Abstract

Aims/hypothesis We determined the impact of insulin pump therapy on long-term glycaemic control, BMI, rate of severe hypoglycaemia and diabetic ketoacidosis (DKA) in children. Methods Patients on pump therapy at a single paediatric tertiary hospital were matched to patients treated by injections on the basis of age, duration of diabetes and HbA1c at the time of pump start. HbA1c, anthropometric data, episodes of severe hypoglycaemia and rates of hospitalisation for DKA were collected prospectively.

Results

A total of 345 patients on pump therapy were matched to controls on injections. The mean age, duration of diabetes at pump start and length of follow-up were 11.4 (±3.5), 4.1 (±3.0) and 3.5 (±2.5) years, respectively. The mean HbA1c reduction in the pump cohort was 0.6% (6.6 mmol/mol). This improved HbA1c remained significant throughout the 7 years of follow-up. Pump therapy reduced severe hypoglycaemia from 14.7 to 7.2 events per 100 patient-years (p <0.001). In contrast, severe hypoglycaemia increased in the non-pump cohort over the same period from 6.8 to 10.2 events per 100 patient-years. The rate of hospitalisation for DKA was lower in the pump cohort (2.3 vs 4.7 per 100 patient-years, p =0.003) over the 1,160 patientyears of follow-up.

Conclusions/interpretation

This is the longest and largest study of insulin pump use in children and demonstrates that pump therapy provides a sustained improvement in glycaemic control, and reductions of severe hypoglycaemia and hospitalisation for DKA compared with a matched cohort using injections

As I understand it, the Junior Doctors in the UK will go on a two day strike tomorrow. I fear that the Government wish to 'break' the BMA. I think that some in the Government would like to see a basically private system of health care in the UK. I feel that the Junior Doctors have been badly treated. But is it a dispute that can be 'won' ?

All this tips are good. But all this are included in some kind of body challenges? Body challenge provides proper diet along with the simple and enjoyable workout which helps to loose weight faster as compared with others. My sister uses this weblink for its own body challenge and she had seen the results within few weeks. Because all health need is the healthy diet. Nothing much more.

Sorry for the late reply. During the junior doctor strikes, the government has been asking patient to go to their pharmacy, at the same time as it is destroying that infrastructure. The two professions really should work more closely together on this.

The petition now has 57,000 votes with 2 months left to go.

A Meta Analysis & Systematic Review reviewed case-control, cohort, and case series about the relationship between Vitamin D & Depression, there seems to be a relationship between both. I wonder whether Vitamin D deficiency can be one of the causative factors of depression, a morbid outcome of depression, mere coincidence or would there be an intermediate process to explain the correlation.

We can always discontinue or reduce any anti-diabetic medication.

Modern guidelines suggest individualised approaches, with no blanket numbers ("treat the patient, not the numbers").

If a type 2 diabetic is on 3 oral drugs (Met+SU+DPP4) it is usually wiser to take out the DPP4 first, if advisable as FBG or HBA1C are getting better, because gliptins are also the least effective among the three drugs.

PS: But if someone is crazy about DPP-4 inhibitors, (as seems the above colleague), one will not go to jail taking out the sulphonylurea first or even metformin if with GI symptoms are annoying enough. Do shared-decision making and let the well informed patient make his or her own choice.

All Best,

Joey

Tax evasion is illegal, but tax avoidance has become a sport, and then perverted.     But it's not just avoiders who are to blame - the tax authorities play the game too.     

An accountant explained to me that some years ago, city boys were paid in gold, in effect "in kind", in the product of their labours, which dioes not attact tax, up to a certain point.  (How this giot around the Truck Act 1794, and its sucessors I don't know) When HMRC realised that this was going on, they got passed rules to prevent it happening in gold.    But only in gold, so the wide boys got paid in Silver.    This process went on through all the precious metals, then the commercial ones, and tghen in vegetable futures!   This lasted for decades, until HMRC twigged the ruse and banned it altogther.    Why is HNRC so dense that they didn't do so from the first?

REEXAMINING THE LINEAR NO-THRESHOLD MODEL

Posted in General clinical at Thu, 21 Apr 2016 08:47:06

You’ve probably gotten an X-ray or CT scan at some point in your life. Most likely, your doctor referred you, but then you might start doubting his/her competence. How can a doctor consciously send you to get zapped by gamma rays and X-rays, effectively nuking your cells and DNA? You can’t feel or see radiation but just hearing the word you’ll probably start picturing hazard symbols, nuclear disasters and maybe you’ll even hear the faint ticking of a Geiger counter. Is it all really that scary?

A short introduction on the linear no-threshold model

 The linear no-threshold (LNT) model was proposed in the early 20th century and the first government agency to adopt it was the National Academy of Sciences (NAS) in 1956. Ever since that time, the LNT model has been the subject of controversy. Every couple of years a story breaks about how inaccurate, misleading and simply untruthful the LNT model is. Most recently, a team from Loyola University took a stab at debunking this decades old theory.

 To start off, the LNT theory is a risk model used by practically all government health agencies and nuclear regulators to form a strict policy of dose limits for workers of nuclear facilities and the general public. At its core, the LNT theory proposes that cancer risk is directly proportional to radiation exposure, hence the inclusion of linear in the name. The second half of the name comes from the simple conclusion that can be made from the linear progression. If cancer risk is proportional to radiation exposure, then there is no safe threshold for radiation. This is where many biologists, epidemiologists and others chime in to say that there is no way to prove low-dose radiation exposure of <100 millisieverts (mSv) per year causes cancer. We’ll explore this argument a little later.

How does radiation cause cancer?

 Ionizing radiation is a known and well-quantified risk factor for cancer. To fully grasp the LNT model, one must first have a basic understanding of how radiation can cause cancer. The lowest dose of ionizing radiation is one nuclear particle that goes through one cell. Either the nuclear particle goes through the nucleus and damages the DNA molecule, or it doesn’t affect it at all. The most damaging is believed to be double-strand DNA breaks. The fact that radiation is a carcinogen is backed up by studies of humans (epidemiology), studies of plants and animals (experimental radiobiology) and studies of cells (cellular and molecular biology). To understand the health effects of radiation, the information from these sources must be combined and studied.

Competing theories

 Since many believe the LNT model to be insufficient and incapable of properly assessing cancer risk below 100 mSv, several theories have been proposed and tested.

The hypersensitivity model claims that there are higher risks associated with low-dose radiation compared to LNT. The threshold theory implies that risk is completely absent below certain levels, a bold statement in my opinion. An even more extreme and controversial theory is radiation hormesis, which claims that low-dose radiation is beneficial and may even prevent cancer.

The reader might be wondering if there is any evidence to support the other theories, and the answer is yes. There is evidence to support them, but it’s limited and in many cases it’s either biased or conclusions aren’t supported by the results.

Do we need the LNT?

  All countries with regulatory nuclear agencies and commissions, with a few exceptions, stand by the LNT because it is supported by a mountain of evidence. These agencies base their recommendations and policies on hard science. Even though most of them have at one point or another concluded that the evidence of cancer risk at sub-100 mSv doses is inconclusive, they don’t see a reason to change their stance.

  Is the LNT model really so bad? It has been the tried and true basis for decades of radiation protection measures. If it didn’t exist, there’s no telling what we’d be up to our ears in; solid tumors, ridiculous working conditions for workers at nuclear facilities and possibly more genetic defects than we could ever imagine.

  Anti-LNTers cry out that there is needless spending and unnecessary expenses associated with nuclear energy. But what if take into consideration the rare, yet evident threat of a nuclear disaster, like Chernobyl or the more recent Fukushima meltdown. They could’ve been many times worse if radiation protection was set up according to any of the other theories. Want to jump start your immune system to prevent cancer? In the delusional hormesis world, a doctor would send you to Chernobyl for a rejuvenating radiation cleanse.  If radioactive waste wasn’t disposed of properly, we could have radioactive sludge seeping into our water supply. Doesn’t it make more sense to be as careful as possible?

The experiment that can finally prove or disprove LNT

Because we are constantly exposed to background radiation and other carcinogens, it’s next to impossible to prove that low-dose radiation from say a yearly X-ray or CT increases cancer risk. Although there are studies showing such a correlation, there are as many studies showing the opposite. That’s why in 2006, scientists attending the Ultra-Low-Level Radiation Effects Summit came up with the perfect experiment to test the LNT model. They plan on building a special laboratory that can test the effects of no radiation on lab animals and cell cultures and compare them to control groups exposed to natural radiation levels. 

LNT- Food for thought

The linear no-threshold theory is a theory not a law. Can it be wrong about the effects of cancer risk at low doses of radiation? Of course it can, it’s a theory after all. But it’s simple, accurate beyond 100 mSv and there’s a general scientific consensus that accepts it. Getting an X-ray or CT scan shouldn’t be scary if it’ll have some diagnostic value for you. For those that argue that LNT policies require exorbitant spending, perhaps cutting military expenditure would be more practical. We can argue back and forth all day, but in the end, I believe that keeping radiation levels as low as reasonably achievable should be our priority.
