Vaccine for the obesity pandemic !

As the world battles the COVID-19 pandemic , there is another pandemic that been going on for decades without any end in sight.

The other pandemic is obesity !

Obesity has caused far more deaths than the COVID-19 pandemic.

The Vaccines promise to end the COVID-19 pandemic.

Wouldn’t it be wonderful if a vaccine can sort the obesity pandemic ? It does not need to be rhetorical question or wishful thinking.

An article in Science magazine reports an association between obesity and a type of body immune cell called macrophages. This raises the possibility of using immunotherapy for obesity.

There is also another tantalising possibility. Behaviours, emotions and eating wrong type of food are often blamed for obesity. What if the entire scientific thinking about obesity is wrong?

In the past, another widespread condition used to be blamed on wrong food and stress. Stomach ulcers used to be very common and very distressing. Modern stressful life, emotions and wrong type of food were universally blamed for stomach ulcers. Then an Australian team proved stomach ulcers were due to an infection. Now stomach ulcers are routinely treated by antibiotics!

Obesity is common among the disadvantaged people in society. All types of infections are common in disadvantaged people. So it is not beyond the realms of plausiblity to hypothesise (suggest) that obesity could be caused by an infectious agent that affects food intake in some way, by possibly affecting sense of taste or smell of smell or feeling of fullness after eating (satiety).

If an infectious agent (e.g bacteria, virus or prion) is indeed found to be responsible for development of obesity, then the vaccines would provide a very easy way to prevent obesity.

Please note: The science magazine article on immunotherapy is based on excellent, high quality scientific work. But the possibility of an infection being responsible for obesity is merely a scientific hypothesis or scientific suggestion. It is based on a personal hunch. It is NOT based on any direct high quality scientific data at this stage !

Risk of Death from COVID-19: does ethnicity matter?

Yes, people from different ethnicities are affected in different ways by Coronavirus.

People of white ethnicity seems to be at lower risk.

People of black ethnicity seem to have higher risk of severe disease but seem to survive better than South Asians in UK.

South Asians who are hospitalised in UK due to severe disease seem to have the highest risk of death.

More work needs to be done to identify underlying the biological factors responsible for the increased risk of death in South Asians in UK.

COVID-19 risk assessment of NHS members : is it an opportunity missed?

The National Health Service had recently embarked on a Risk assessment exercise of its staff to assess the Vulnerability of individual members to Coronavirus infection ( COVID-19).

The exercise is being done with good intentions. Given the unprecedented situation of the pandemic and lack of concrete data , the exercise seemed to have steered away from firm “one size fits all” type of recommendations.

Given the uncertainties with the currently available data on various forms of protection ( from simple surgical masks to shielding) , the exercise could have been a starting point for an nationwide intervention study .

An opportunity seems to have been missed and if there is a second wave, NHS might regret not learning from the first wave.

Please do add your opinion at the rapid response section of the BMJ.
