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 !

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.

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.

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.

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 !

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“.

“Think Positive “ and live longer !

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.

New drug combination for Ovarian Cancer (Olaparib and Bevacizumab)

New trial data presented at the ESMO cancer Congress 2019 in Barcelona, Spain, show excellent results for the combination of Olaparib and Bevacizumab. The combination looks likely to become standard of care in at-least a subgroup of patients.

The expert discussing the trial data did raise the possibility that most benefit seems to come from Olaparib in patients with BRCA mutations and whether Olaparib alone instead combination is enough for this group. More data is awaited.

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.

Low Carb Diet

High carbohydrate diet can make a person put on weight.

The extra weight can put a strain on the knees and logic dictates that over time this can cause knee problems due to excessive “wear and tear”.

So would a Low-Carbohydrate and Low-Fat Diet help to relieve Pain in Individuals with Knee Osteoarthritis.

Yes, low carb diet can indeed have positive effect on Knee pain.

A study testing the efficacy of two dietary interventions found that low carb diet can reduce pain intensity .

Surprising Number of Americans Believe Alternative Therapies Can Cure Cancer

woman holding white laptop between women

Photo by rawpixel.com on Pexels.com

A recent National Cancer Opinion Survey found that a significant Number of Americans Believe Alternative Therapies Can Cure Cancer.

Nearly four in 10 Americans (39%) believe cancer can be cured solely through alternative therapies such as enzyme and oxygen therapy, diet, vitamins, and minerals.

Even many of the respondents with direct cancer experience—people who have or had cancer and family caregivers—believe cancer can be cured solely through alternative medicine.(22% and 38%, respectively).

The American survey also found that younger people are the group most likely to hold these views: 47% of people ages 18 to 37 and 44% of people ages 38 to 53.

It is counterintuitive that the generation with access to vast online information at the swipe of a finger holds such unscientific views. One wonders whether the social media is inadvertently promoting misinformation.

Can Turmeric control cancer ?

Turmeric powder

 

Turmeric is an orange coloured spice widely used in Indian dishes.

Turmeric has been used in Indian traditional medicine (Siddha and Ayurveda).

Turmeric has anti-inflammatory and anti-Cancer properties when tested in laboratories.

Remember – a potential to be beneficial (based on lab studies) is not the same as being proven to work in humans. Lot of substances which are promising in the laboratory eventually turn out to be useless in humans.

If you search PUBMED database- which is an online database of scientific papers- you will find hundreds of papers pertaining to medicinal use of turmeric and its key ingredients such as curcumin. But unfortunately among the many hundreds of published papers, there are very few human trials which have explored turmeric as a anti-cancer treatment.

Inspite of the positive anectodal reports on various internet sites, the available scientific evidence for use of turmeric as an anti-cancer treatment is very spare. ( references below).

Hence it is not worthwhile using turmeric as a cancer treatment.

If you do like Indian dishes, use turmeric as a spice in your normal diet.

But do stay away from the supplements which are sold with health claims.

Does Cranberry juice relieve bladder symptoms due to radiation cystitis?

bowl of red round fruits

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 .

Disclaimer: Please note- This is NOT medical advice. This blog is purely for information only. See your own doctor to discuss options.

Low carbohydrate diet

The advocates of low-carb diet received a scientific boost recently.

An American trial, published recently in the British Medical Journal, compared the effects of low-carb-high-fat diet with high-carb-low-fat while keeping total calories and protein intake constant.

This elegantly done trial shows that carbohydrates are bad for weight loss. A diet with a combination of low-carb-high-fat content was the winner in this trial and it promoted energy loss and helped maintain weight loss.

Can alcohol cause cancer?

Yes,  worldwide, 1 in 20 cancers are attributed to alcohol .

How much drinking causes cancer?

“Even modest use of alcohol may increase cancer risk, but the greatest risks are observed with heavy, long-term use”

“The more that a person drinks, and the longer the period of time, the greater their risk of development of cancer, especially head and neck cancers”

Are light drinkers at risk ?

Risk of cancer is present at  even at low levels of consumption.  Hence, the World Cancer Research Fund/AICR makes the following recommendation: “If alcoholic drinks are consumed, limit consumption to two drinks a day for men and one drink a day for women.” They also recommend that, “for cancer prevention, it’s best not to drink alcohol.”

Is wine less risky than spirits?

No,  the risk is present “regardless of the specific type of alcoholic beverage (ie, beer, wine, or spirits/liquor)”

Which cancers can arise due to alcohol?

Alcohol is causally associated with Mouth, Throat, Gullet, Liver, Breast and Bowel cancers.
