Are Routine blood tests essential during follow up of low grade Lymphoma?

Bloods tests have the potential to pick up various abnormalities including cancer related abnormalities during follow up of cancers.

But , many patients would be surprised to know that there is ongoing debate about usefulness of routine blood tests atleast in some cancers !

In a recent study, Australian investigators assessed the role of routine blood tests during monitoring of patients with low grade lymphoma.

They found that routine blood tests rarely found or detected disease progression in patients who did not have any symptoms.

Can a Protein rich diet lead to a longer life ?

Yes, a protein rich diet can lead a longer life and reduce risk deaths due to heart diseases.

Before you rush to relish your burger or steak , please note the evidence for beneficial effect is very much in favour of plant proteins than animal proteins.

So Befriend your Beans !

And Love your Lentils !

Can you get Coronavirus infection more than once?

If you are one of the unlucky ones to have already been infected with Coronavirus infection but recovered from it, can you become unlucky again and get another Coronavirus infection later this year ?

Unfortunately, the answer is a YES.

Some Viral infections can sometimes lead to life long immunity. For example, most people who had chicken pox as a child tend to have lifelong immunity and it would be uncommon to get chicken pox again. (except in some circumstances).

But infection with ‘Coronavirus causing COVID-19’ doesn’t seem led to long lasting immunity or resistance to a second Coronavirus infection.

A Newspaper report on a study by a team from King’s College London suggests that susceptibility to a second infection may occur as short as 3 months in some patients. This because the level of antibodies produced by the immune system after first infection start to fade away within a few months in some patients.

If confirmed, this is probably one of the most worrying news during this pandemic.

This study result could also affect Vaccine development and how frequently it may need to be administered.

Can Coronavirus linger in air, and cause COVID-19 by spreading through air ?

Normally many flu-like viruses spread by direct or close contact.

Because Virus containing droplets are heavier than air, scientifically it is thought that when someone coughs or sneezes, virus particles quickly fall to ground or surrounding objects.(“like a brick or stone falling to ground“).

But a group of scientists and WHO have raised the possibility that coronavirus can stay in air for longer periods, float around and cause more infections. (“float like a balloon“). This is called air-borne transmission.

What does it mean?

If confirmed– this means “closed spaces” are high risk even if you maintain 2 metre distance from an infected person. AVOID CLOSED SPACES.

As many people in UK do not wear masks in public places, there is a high chance of second wave of infections in the coming weeks as lock down is eased. WEAR A MASK.

It also means avoiding non-essential visitors to hospitals so that visitors cannot catch the infection or pass the infection to vulnerable patients. AVOID NON-ESSENTIAL VISITORS AT HOSPITALS.

If air borne transmission is confirmed, it is also bad news for the coming winter.

If Coronavirus is still in community and not eliminated by winter, air-borne transmission is likely to result in further wave of infections.

This is because Winter means more closed spaces and more chance of infection !!!!!!

STAY SAFE

Can Vitamin D prevent respiratory infections such as COVID-19 ?

No conclusive evidence yet.

Some studies suggest a protective effect but two recent “official” reviews in UK has concluded the following.

(1). “The available evidence does not support vitamin D supplementation to prevent acute respiratory tract infections in the general UK population”.

(2). “There is currently no evidence to support vitamin D supplements reducing the risk or severity of covid-19″.

Health effects of vitamin and mineral supplements

In Western countries, upto two thirds of people take vitamin and mineral supplements regularly.

Many people think it’s common sense to take supplements. Many people don’t realise mega doses of vitamins can cause harm. Paradoxically the people who don’t have a healthy diet are less likely to supplements than those who have a well balanced diet.

A recent article in BMJ reviews the evidence regarding “Health effects of vitamin and mineral supplements” and concludes that “Randomised trial evidence does not support use of vitamin, mineral, and fish oil supplements to reduce the risk of non-communicable diseases”.

This article is certainly a “food for thought”

Dexamethasone: “There’s Lot more Life in that Old Dog Yet”

Dexamethasone is one of the commonly used steroids in Clinical practice. It is used to treat allergies; it is used as an anti-inflammatory drug for all sorts of inflammation affecting various part of body.

In cancer patients, Dexamethasone is certainly used widely. It is used as an anti-sickness drug, appetite stimulant, to reduce swelling around brain tumours, and as an anticancer drug in Prostate cancer.

Dexamethasone has now found to be useful in treatment of Corona Virus infection.

In one of the largest Covid-19 trial, the RECOVERY trial- this low cost drug has been found to improve survival of patients particularly those who need Ventilation.

A word of caution though, it did not benefit patients with mild infection due to Coronavirus.

New medication for prostate cancer

The Male hormone- Testosterone feeds the prostate cancer. Shutting down testosterone production in men can help to control prostate cancer.

Advanced prostate cancer is currently treated first by regular hormone injections.

The hormone injections reduce the Testosterone in men.

Now a new medication, called Relugolix, has been successfully tested in clinical trials. Relugolix, unlike other first line hormone injections , can be taken by mouth instead.

Relugolix also has the advantage of not only working rapidly but also has the advantage of stopping to work quickly when it is withdrawn. This is unlike the injections which take a while to work but also do not stop working quickly when injections are stopped.

Can Vitamin K help fight Coronavirus?

Possible but like every other observational study, take it with pinch of salt.

Further evidence from well conducted trials are needed before it can be recommended as a COVID treatment.

In mean time, it’s better to stick to natural sources of vitamin such as those mentioned in the newspaper article ( spinach, broccoli, green vegetables, blueberries, all types of fruit and vegetables).

Chloroquine not useful for treating or preventing Coronavirus infections

Randomised Study is the considered as the gold standard for trials.

Placebos are dummy pills . Placebos are inactive drugs that look like the real drug but are essentially sugar coated dummy pills.

Trials which involve a placebo vs active drug comparison are considered one of the best trials for some clinical situations.

A “randomised trial” involving “Chloroquine ” and “placebo ” has been published in NEJM .

A randomised trial suggests Chloroquine is not better than a placebo in treatment of COVID.

Another randomised trial suggests, Hydroxycloroquine is not useful for prevention of COVID-19.

In summary, Hydroxycloroquine is not useful either as COVID-19 treatment or as a COVID-19 preventative drug as advocates in certain countries.

Please Note : Chloroquine and HydroxyChloroquine are different drugs but have broadly similar effects.

Does Eating Eggs lead to Heart problems?

No, Eating Eggs in moderation is not associated with increased Heart problems.

Heart diseases are one of major killers in Men and Women. In the past, Cholesterol was exclusively blamed for most of the Heart problems. Nowadays, such a simplistic view has been abandoned. We now know that Heart diseases are due to a complex set of poor diet and life style.

Previously Eggs which have lot of dietary cholesterol have been subject to lot of bad press.

A recent pooled analysis of good quality data shows that ” moderate egg consumption (up to one egg per day) is not associated with cardiovascular disease risk overall, and is associated with potentially lower cardiovascular disease risk in Asian populations.”

So like everything else with regards to diet , moderation is the way to go !

Cancer and COVID-19

Coronavirus infection seems to be more deadly in patients whose immune systems are not functioning very well.

So cancer patients who have reduced immunity due to chemotherapy are understandably at higher risk of death.

Among cancer patients, those patients whose cancer is progressing ( i.e cancer not under control ) seem to at even more from COVID-19.

A study presented at the ASCO ( American Society of Clinical Oncology) reports that ” after a COVID-19 diagnosis, patients with progressing cancer were found to be 5.2 times more likely to die within 30 days”.

So stay safe and consider shielding if your cancer is not under control .

Furthermore, there is lot of interest in use of Chloroquine, an anti-malaria drug for treatment of COVID-19. The study reports that “Treatment with the drug combination hydroxychloroquine and azithromycin was also strongly associated with greater risk of death”. So best to avoid unproven treatments outside a trial setting.

Is Chloroquine useful in treatment of Corona Virus?

Chloroquine and the related drug Hydroxy-Chloroquine are drugs commonly used to prevent and treat Malaria infections; and treat some Joint conditions.

During the initial stages of COVID-19 pandemic, there were some reports of Chloroquine being useful in treating Corona Virus.

A Chinese trial published in British Medical Journal BMJ now reports that ” Administration of hydroxychloroquine did not result in …. any meaningful antiviral benefits… compared to standard of care alone in patients admitted to hospital with mainly persistent mild to moderate covid-19”

Chloroquine was not only useless but it had significant side effects in a minority. So Chloroquine or Hydroxy-Chloroquine should not be used routinely outside a clinical trial setting.

Face Masks: Should Public wear face masks because of Corona Virus pandemic ?

Should Public wear face masks because of Corona Virus pandemic ?

Yes.

In some of the Asian Countries there has been universal acceptance of face masks even before Corona Virus pandemic. Hence, it is not surprising that there is wide spread use of face masks during this pandemic .

In USA, after initial hesitation, CDC now recommends use of cloth face masks by public.

In Germany, many states have made face masks compulsory.

In UK, there has been no official recommendation about widespread use of face masks.

With so many unknowns, it is prudent to follow the advice published in British Medical Journal : WEAR A MASK !!

Does air pollution in cities make your jogging and walking less beneficial ?

Yes, air pollution is now being recognised as an important cause of death in major cities and towns.

So avoid major roads and very busy streets.

Any benefit you might accrue from exercise can be wiped out by heavy air pollution if you are jogging on a heavily congested road.

Is it worthwhile to be on constant vigilance for any symptoms which might indicate cancer has come back ?

Unfortunately no.

A Cancer charity advices to watch out for symptoms.

Constant Vigilance for cancer recurrence has its own downsides.

After successful cancer treatment, being on look out for symptoms constantly wrecks your quality of life for minimal benefit in most cases.

Many trials of intensive screening shown no benefit for early detection of secondary cancer. ( note- this is different from the ongoing debate about benefits of primary cancer detection with cancer screening programs such as Mammograms, PSA screening, bowel cancer screening).

Cancer patients are quite often aware of own body and pre-existing aches and pains.

The best thing is to act promptly if there are “any new and persistent symptoms” . For vast majority of cancer patients, there is no need to do a frequent check list of possible symptoms, on a daily or weekly interval.

Do NOT be on constant vigilance for all possible cancer symptoms unless you have been specifically advised to do so by your oncology team.

Eternal Vigilance for months and years can wreck your quality of life.

Think Positive. Nothing is lost when you maintain hope.

Can Vitamin D protect against respiratory infections ?

Can Vitamin D protect against Respiratory infections ?

The answer is yes, according a paper published in the BMJ ( British Medical Journal) in the recent past.

With Corona Virus ( COVID 19) pandemic raging in Europe and USA, there is lot of interest in treatment and naturally prevention of Respiratory tract infections.

It is also understandable why a paper published in Feb 2017 is one the most read BMJ paper in March 2020.

The paper analysed data from “25 eligible randomised controlled trials involving a total of 11 321 participants”.

The study concludes ” Vitamin D supplementation was safe and it protected against acute respiratory tract infection overall. Patients who were very vitamin D deficient and those not receiving bolus doses experienced the most benefit.”

Plain English Medical Letters to Patients

Writing letters to patients in plain English without medical jargon is a gift that only a few doctors possess.

Personalising complex medical terminology in a letter dictated over a few minutes is NOT an inherent skill possessed by many doctors including those who are native English speakers.

Dictating Plain English medical letters would take considerable time and effort – particularly if letters are going to succinctly summarise everything from a medical consultation.

In UK, with regards to Cancer, we are lucky to have cancer charities who do a good job of providing information in plain English ( E.g Cancer Research UK, Macmillan Cancer Support, Prostate Cancer UK).

Cancer Patients in UK also have the support of Cancer Nurse Specialists ( CNS ) who do a fantastic job of guiding patients through their cancer journey and clarify all medical jargon to patients.

Other specialities might not have the resources that are available to cancer patients. But, on the whole, Clinic Time slots are precious. Many UK specialists have long waiting lists.

So if further time and effort is to be expended in busy clinics for dictating plain English Letters – in addition to the usual Medical letters to GP – good clinical evidence is needed to demonstrate that separate plain English letters do benefit patients in a meaningful way.

Please do read the BMJ article and put forward your views in the rapid response section.

Chemotherapy for Elderly Prostate Cancer patients with Advanced prostate cancer

Chemotherapy has been shown to unequivocally improve prognosis of advanced prostate cancer patients.

The survival was found to be improved by an average of 10 months with addition of chemotherapy to long term hormone therapy in a large clinical trial.

Prognosis without chemotherapy was 71 months and prognosis with chemotherapy was 81 months.

But this extra benefit from chemotherapy comes at a cost.

Chemotherapy can be toxic with occasional life threatening side effects. Some elderly patients are frail and others may have diseases affecting heart, lung and brain.

So some patients after carefully weighing up benefits and risks might decline chemotherapy.

This need to weigh up risks and benefits is sometimes very difficult for both patients and doctors before a decision is reached whether to opt for chemotherapy or not.

Express your views at the BMJ rapid response section.

Do omega 3 supplements provide protection from Stroke and Heart diseases?

It is a common belief that omega 3 fatty acids provide protection from strokes and heart attacks, and improve overall health.

A review from the esteemed Cochrane collaboration pours cold water on this belief.

The review concludes that omega 3 provides ” little or no meaningful effect on the risk of death from any cause”.

They conclude that “omega 3 supplements probably makes little or no difference to risk of cardiovascular events, coronary heart deaths, coronary heart disease events, stroke or heart irregularities”.

The review did find “moderate evidence that ALA, found in plant oils (such as rapeseed or canola oil) and nuts (particularly walnuts) may be slightly protective of some diseases of the heart and circulation”.

However, the effect was very small. They estimated that “143 people would need to increase their ALA intake to prevent one person developing arrhythmia”.

They also estimated that “One thousand people would need to increase their ALA intake to prevent one person dying of coronary heart disease or experiencing a cardiovascular event”.

Overall the review finds that overall “omega 3 provides little if any benefit at all”.

Walking is good exercise

New year. January. First month of a New year – it’s the time of year many people take a look at their lifestyle and vow to eat better, exercise better and live better.

Many people consider Gym or Health Club membership.

But Exercise doesn’t need to cost a lot. Being active, doesn’t need to be regimented.

Simply walking anywhere is good compared to no exercise at all. Walking in the Park or Quiet streets has lot of benefits.

Good article in BBC on the benefits of walking.

A word of caution though !

Avoid Walking or Jogging near busy roads so that the benefits of walking are not negated by pollution.

Exciting new immunotherapy treatment !

Test tube lab

The holy grail of cancer treatment is design a drug that is highly lethal to cancerous tissue but completely spares the normal tissues.

Scientists at Cardiff University have discovered immune cells which could provide such a clever treatment.

It is still early days. The principle has been proven in lab. But to be a useful treatment that can be used in cancer patients, it is still far off.

This particular novel form of immunotherapy using T cells is still in early stages and so many hurdles have to be overcome before this discovery could be employed in cancer treatment.

Nevertheless, it has certainly excited many researchers in the field of cancer and the paper has been published by a premier scientific journal.

Do the morning people have it all ?

Picture of morning bird against rising sun

There is definitely truth in idiom that “The early bird catches the worm”.

Are there any other life advantages for the early risers compared to those who hate early mornings?

A paper in BMJ says the women with “morning preference” have less risk of breast cancer compared to the evening people.

So there are advantages for those who can jump out of their bed easily in the morning but it is a different question whether the late risers can train themselves to be early risers !

Does alcohol increase of breast cancer?

Yes, Alcohol does substantially increase the risk of Breast cancer.

Very few people seem to be aware of the risks.

Previously it was thought that heavy drinking is responsible for harmful cancer effects.

But studies from U.K and U.S.A have subsequently shown that even light to moderate drinking can increase the risk of breast cancer.

A very large study involving more than 1,250,000 middle-aged women in the United Kingdom ( enrolled in the Million Women Study) showed that “Low to moderate alcohol consumption” in women increases the risk of breast cancer and certain other cancers.

In a study involving more than 88,000 women from United States, also showed that light to moderate drinking increases the risk of breast cancer.

So keep counting the alcohol units during the festive time.

Is whole milk harmful ?

In years gone by , many viewed milk as a wholesome healthy food. Government encouraged consumption of milk by providing free milk.

But in recent years, milk is viewed with suspicion.

Vegans shun milk and diary products.

Perhaps the Vegans got it right all along at least as far as whole milk is concerned.

A very large study involving 168 153 women and 49 602 men was published recently in British Medical Journal. The study found that whole milk intake is associated with increased risk of death from heart problems and from some cancers such as lung cancer, ovarian cancer, and prostate cancer.

Interestingly “Cheese and yogurt intake was NOT associated with increased risk of death”.

The risk was also less with “skimmed or low fat milk”.

Futile antibiotic treatments

Infections are normally highly treatable with antibiotics.

But when someone is dying , the body’s immune system gets weaker. Hence infections quite often occur as part of the dying process.

Treating these infections are often futile. But human nature is inclined to “fight and survive” by all means. So quite often powerful antibiotics are used to treat these infections in dying patients.

There is an ethical argument against futile treatments.

There is also the risk of antibiotic resistance in general population if antibiotics are used inappropriately.

Can long working hours kill you?

Yes, it can.

It has been well established by systemic review that working long hours can lead to excessive heart attacks. ( ref 1).

A recent French study indicates that working long hours can lead to increased risk of stroke ( Long hours defined as more than 10 hours on at least 50 days per year in this study) (ref 2).

So look after yourself and don’t push yourself too hard !

Are some people fat because of their “gut bacteria mix” is of the wrong sort?

Some people are able to eat everything they like and do not gain much weight (as long as they don’t go over the top).

But others have to just smell a chocolate or a cake and they put on weight (even though this comment is made jokingly some people are so exasperated with their weight gain in-spite of all diets !!!).

Could this discrepancy be related to the having “wrong cocktail of Bacteria in their gut”.

Some scientists seem to think so. An intriguing proof of concept study has been published in Nature Medicine which is a very esteemed science journal.

Read this thoroughly interesting and balanced article on The Atlantic website.

Yes, stress can increase risk of serious infections.

Based on personal experience, anecdotally many people would vouch for the fact that stressful events makes them more prone to illness. But strong scientific evidence has been spare.

Can weather affect joint pain?

Yes, weather can affect joint pain.

A study involving 2500 people conducted by University of Manchester study showed that “people with arthritis feel more pain on humid days”

The study reports that “Damp and windy days with low pressure can increase risk of experiencing more pain than normal”

“Cold, damp days also made pain worse but interestingly pain was not made by temperature alone”.

Other studies in the past have also found a “significant correlation between humidity and pain“.

Is it a case of “chicken vs egg” in that what came first. Do healthy people have a optimistic outlook and pessimistic people have lot of social, personal and health problems. Do life problems make people pessimistic or being optimistic makes one do better?

Researchers have adjusted the data for confounding factors. Evidence so far is very intriguing.

And the next question is – can one learn to be optimistic, change personality and have beneficial health effects. We don’t know at present.

Crowdfunding expensive stem cell therapies

Crowd fund metaphor

If you have come across a desperate request to crowdfund an expensive stem cell therapy, read this well researched BBC article before you contribute.

Hope is a powerful driver particularly when someone is facing immense difficulties in life. Human beings have a natural inclination to fight against all odds and it seems to be inbuilt in our DNA and psyche.

But not all promising treatments do help desperate people searching for a cure.

Dietary advice: take it with a pinch of salt

Official dietary advice as well as various “Diets” promoted by various celebrities tend to be very prescriptive. They often give the impression that the evidence behind everything they promote is very clear cut.

But truth is far more murkier ( I might say more “mish mash “).

A new study analysis of old data comes to a different conclusion about “red meat”. This is in fact not surprising as the evidence for various Dietary guidelines and “Diets” are not usually robust and watertight and involves lot of assumptions.

What is the take home message:

Eat “everything you like” in moderation and try to make it as balanced as possible with substitutes for things you avoid !!

Avoid processed food as much as possible and eat fresh.

Don’t be surprised if the next two studies on this topic reach three different conclusions.

Prostate Bed Radiation can be avoided or delayed in many prostate patients following surgery

A large UK trial shows that lot of men undergoing surgery for prostate do not need Immediate follow-on radiation straightaway.

Trial data was presented at ESMO conference in Barcelona.

Radiation can be entirely avoided in many patients at high risk of relapse and it can be safely delayed until there is definite evidence of relapse in selected patients for months and years.

Waiting and watching is certainly prudent in some patients rather than rushing in with radiation so as to avoid side effects.

Combined data analysis using study data from France as well as Australian and New Zealand trials confirm these findings.

Exercise: Anything is better than nothing

Many people put off exercise thinking it needs to be a planned activity with time allocated for it.

A paper published in British Medical Journal ( BMJ) reports that any exercise is good and contributes to good health compared to no exercise

The recent UK guidelines also advises to “clock up few minutes at a time” whenever and wherever you can. (UK Chief Medical Officer).

You don’t need to run a marathon or join a running group. Just taking the stairs rather the lift would be good.

Is Vegan diet the most healthy ? Are there any risks from Vegetarian diet?

Life would be very simple if we can have clear cut answers with regards to the best diet for everyone’s health.

A recent study published in BMJ indicates that while Vegan diet reduces risk of heart problems it can increase the risk of strokes.

The results might seem confusing and scientists would be certainly seeking more answers. But don’t be surprised if another study from some other research group comes up with a contradictory result. That’s normal in science.

What’s most important is to realise that there are no easy scientific answers to most scientific questions. Research quite often shows unexpected results. What is a logical scientific question quite often throws up unexpected answers.

Overall, the message is “have a well balanced diet” without omitting essential nutrients.

What news can you trust as a cancer patient?

A Cancer diagnosis is terrifying and upsets all the carefully crafted life’s plans.

Many cancer patients would like to have in-depth information about cancer. It is quite natural and logical to expect “black and white” information cancers. But cancer is always associated with uncertainty.

Well meaning but ill informed people sometimes inadvertently bombard cancer patients with fake news. Even worse, there are charlatans who would try to sell unproven treatments to vulnerable cancer patients.

There is a good article in Observer about this “cancer fake news”.

If you are not sure about information you have read on the net, ask your doctor to clarify.

If you prefer a independent person , ring the helpline of independent charities such as Cancer Research UK or Macmillan.

Can fruit juices increase risk of cancer?

Instinctively, many people would think of fruit juices as healthy. Many would not associate fruit juices with cancer.

The conclusion – sugar is bad from cancer point of view.

Taking up Exercise in middle age: is it worthwhile?

You could have been a ‘couch potato‘ all your life.

Is it worthwhile starting exercise now?

Yes, says the paper published in British Medical Journal.

The study involving nearly 15,000 people found that irrespective of your past, taking up physical activity in middle and old age is beneficial.

The study concludes “Middle aged and older adults, including those with cardiovascular disease and cancer, can gain substantial longevity benefits by becoming more physically active, irrespective of past physical activity levels and established risk factors.”

So get going !!!!!
