Cochrane evaluations are non foolproof.  There is e'er the GIGO problem.  But Cochrane surveys are usually every bit expert every bit nosotros get

The £653million spent on drugs to stave off a flu pandemic was ‘money thrown downward the drain’, a damning written report flora yesterday.

The drugs – Tamiflu too Relenza – were stockpiled at huge toll yesteryear wellness chiefs inwards the promise they could stalk the effects of a pandemic.

The volume buy was triggered inwards 2005 when Government scientists warned that every bit many every bit 700,000 Britons could exceed from deadly plane flu.

After millions of doses were stockpiled, spending on the drugs escalated even too thence farther amongst the outbreak of swine flu (H1N1 virus) inwards 2009, the showtime pandemic inwards xl years.

The anti-viral medicines were purchased to cut down admissions to infirmary too unsafe complications from flu such every bit pneumonia.

But the drugs piece of occupation no ameliorate than remedies such every bit paracetamol, according to an analysis yesteryear researchers. There are also claims that vital information from clinical trials was withheld from regulators, researchers too doctors.

The report, which analysed information from published too unpublished trials, concludes at that topographic point is no evidence to demo that the drugs cut down infirmary admissions or complications.

It also says the 2 drugs produce shorten the symptoms of flu but alone yesteryear one-half a twenty-four hours – nearly the same every bit some over-the-counter drugs.

The review yesteryear Cochrane, an independent, international network of researchers, also flora Tamiflu had side effects including a higher direct chances of psychiatric too kidney symptoms.

The authors of the report, published inwards the British Medical Journal (BMJ), called for an immediate halt to stockpiling of the drugs on the footing of the evidence.

Dr Carl Heneghan, professor of evidence-based medicine at Oxford University, said: ‘The coin spent has been thrown downward the drain. There is no credible agency these drugs could forestall a pandemic.’

The drugs worked no ameliorate at relieving symptoms than over-the-counter medicines but had potential to ‘cause cracking harm’, he said.

Influenza A virus subtype H5N1 minute author, Dr Tom Jefferson, a clinical epidemiologist, said: ‘The evidence doesn’t justify stockpiling – nosotros should halt it.’

The investigators said at that topographic point had been ‘multi-system failure’ which included the role of regulators, the European Medicines Agency – which approved licensing of the drug inwards Europe – too the drugs watchdog Nice.

Investigators from Cochrane state the master evidence the drug companies gave to the Government was incomplete. They used a huge amount of information alone made available yesteryear manufacturers Roche too GlaxoSmithKline later ‘years of struggles’, said BMJ editor-in-chief Dr Fiona Godlee.

The findings, based on 46 trials involving to a greater extent than than 24,000 people, cast incertitude on whether the drugs are worthwhile fighting flu too advise ‘insufficient grounds’ for using Tamiflu every bit a preventive measure.

Roche said it ‘fundamentally disagreed’ amongst the findings.

But Professor Wendy Barclay, chair inwards flu virology at Imperial College London, said other evidence showed the drugs benefited sick important women too stockpiling had been ‘prudent’.

Roche U.K. medical managing director Dr Daniel Thurley said: ‘Roche stands behind the wealth of information for Tamiflu.

The report’s methodology is oft unclear too inappropriate, too their conclusions could potentially receive got serious populace wellness implications.’

The Department of Health said: ‘Tamiflu is licensed around the Earth for the handling of seasonal flu too is a licensed production amongst a proven tape of safety, lineament too efficacy. We regularly review all published information too volition regard the Cochrane review closely.’


Viagra increases the direct chances of pare cancer: Men who used the drug were 84% to a greater extent than probable to larn melanoma, study claims

There could hold upwards something inwards this.  Viagra users are presumably less robust by too large but that does non explicate that the ill-effects were confined to melanoma

It has boosted loved lives across the Earth - but novel query suggests men who accept Viagra may significantly increment their direct chances of pare cancer.

American researchers flora those who took sildenafil, to a greater extent than commonly known every bit Viagra, were 84 per cent to a greater extent than probable to larn melanoma, the most deadly shape of the disease.

It is idea the impotence drug may behaviour upon the same genetic machinery that enables pare cancer to move to a greater extent than invasive.

However the researchers add together that because the study is preliminary, it is every bit good early on to advise men to halt taking the picayune bluish pill.

'Because it’s only 1 early on study, no 1 is suggesting that men halt taking Viagra to process erectile dysfunction,' study co-author Dr Abrar Qureshi, professor of dermatology at Brown University, told NBC News.

But he advised those taking Viagra who receive got a high direct chances of melanoma should mean value nearly speaking amongst their doctor.

He added that the direct chances of less unsafe - too to a greater extent than mutual pare cancers, such every bit basal jail cellphone or squamous jail cellphone cancers - was no higher inwards men who took the drug.

The study, of 26,000 men inwards the U.S too China, analysed information from the Health Professionals’ Follow-up Study, which collects information nearly virile mortal healthcare workers (including doctors).

Of those included inwards the study, the average historic menses was 65 too half dozen per cent had taken the erectile dysfunction drug.

The research, published inwards the magazine JAMA Internal Medicine this week, showed that men who took Viagra fifty-fifty 1 time had double the direct chances of developing melanoma.

Dr Qureshi added that direct chances factors for pare cancer - such every bit the amount of sunlight exposure a homo had too household unit of measurement history of the illness - had been taken into account.

Other well-known side-effects of Viagra include heartburn, nausea too headaches.  The drug is also unsuitable for men amongst angina or really high blood pressure
