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 !

People with sunny disposition seems to live longer.

Having a positive outlook on life seems to protect heart.

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.

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.

Celery Juice: Super Juice ?

Why Celery Juice is popular now?

Every year some type of food or fruit trends on the social media after being hyped by celebrities and Influencers.

Unfortunately, it seems Celery Juice is trending now.

Just because something is endorsed with good intentions by well meaning people doesn’t mean you have to blindly believe them.

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

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 .

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

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?

pexels-photo-533257.png

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.
