Is the new variant of Coronavirus more dangerous?

Yes and No

The new mutant is more dangerous because it is more easily transmissible from person to person. The new variant is now spreading very rapidly in London and South East of England.

But, so far, the new variant has NOT been found to be more deadly than the original version. The new variant does NOT seem to have substantially increased the risk of hospitalisation and death anymore than the original version of coronavirus.

Emergence of this new mutant (called variant VUI-202012/01 fall) is a certainly a worrying development in this pandemic.

The mutations has made the new strain 70 per cent more transmissible but scientists do not expect these mutations to reduce the effectiveness of vaccines.

Tests are being carried out to confirm that the existing vaccines would still have a high degree of protective affect.

It is an evolving area and we have to hope that the new variant doesn’t make things worse than they are now !

Does Cranberry juice relieve bladder symptoms due to radiation cystitis?

Many people do look for natural remedies to help with their symptoms.

Anectodally, many patients undergoing radiotherapy have reported that Cranberry Juice has eased their radiation cystitis symptoms.

What is the scientific evidence behind it ?

Should all patients having cystitis symptoms during radiotherapy take cranberry juice?

There is certainly scientific basis to expect benefit from Cranberry Juice.(1).

A lab study and a volunteer study (with volunteers from Japan, Hungary, Spain and France) has shown that certain chemicals in Cranberry can make bacteria ‘less sticky‘ to urinary tract walls and hence potentially reduces virulence of the bacteria.(1). But subsequent large studies have NOT confirmed any large benefit from Cranberry in terms of treating or preventing urinary tract infections. (2)(3).

But Radiation Cystitis is not due to bacterial infections although infections can co-exist sometimes. Hence the use of Cranberry has been studied separately in patients undergoing radiation therapy.

A New Zealand study involved 41 men undergoing radiotherapy for prostate cancer. Taking Cranberry (one capsule a day at breakfast) was found to reduce symptoms of pain and burning. (4).

On the other hand, in a study from Canada involving 112 patients , consumption of Cranberry juice compared with apple juice had no effect on radiation cystitis symptoms. (5).

Another study from United Kingdom was inconclusive because of poor patient recruitment and poor compliance. (6).

So the scientific evidence is inconclusive at present.(7).

Practically, if someone is keen to try it – the best course of action – ( for someone not intolerant of cranberry juice) – is to try it and see whether it offers any symptomatic benefit .

There are prescription medications available to help with radiation cystitis symptoms.
