TREATING COVID WITH BLOOD

We have previously covered proposed treatments for COVID-19, in particular hydroxychloroquine, and explained why we shouldn’t look for a magic cure for this disease. Viruses are difficult to treat, and ultimately supportive treatment appears to be best we can achieve. But an editorial published in BioMedicine Central appears to show a novel treatment for the most ill patients, one that may have flown under most people’s radar.

“A novel treatment approach to the novel coronavirus: an argument for the use of therapeutic plasma exchange for fulminant COVID-19”

An interesting title. Lets dissect it.

SUMMARY

- Blood is made up of many different components

- The immune system recognises the virus and produces antibodies against it to neutralise it

- These antibodies float in the blood plasma, a watery solution

- The plasma can be extracted from donated blood, and given to patients suffering from COVID-19

- So far evidence suggests it can help treat the most seriously affected patients.

WHAT IS IN OUR BLOOD

To understand this we must first understand what our blood is made of. Most people know that blood functions to transport oxygen from our lungs. But this is an oversimplification. Blood has many different functions:

Transport: along with oxygen it transports sugars, fats, protein subunits throughout the body. This is done with the watery PLASMA of the blood.

Clot: cells and protein structures act to plug any holes that form from cuts and damage. This is done by the PLATELETS in the blood

Immunity: Immune cells respond to bacteria, viruses, parasites in the blood and body. They target these pathogens, identify and tag them with antibodies, and ultimately destroy them. This is done by the WHITE BLOOD CELLS.

And many more functions that we won’t bore you with.

IMMUNITY

It is this last point that is of interest to us. Our immune system consists of white blood cells that can recognise invading organisms in the blood, around cells and even invaders hiding within our own cells. All cells have protein markers on their surface, no matter if its human cells, bacterial, viral, fungal etc. These markers can be highlighted and targeted by specialised white blood cells, who in turn produce antibodies against these markers. Think of antibodies as handcuffs with flares attached: once attached other white blood cells use this information to find and destroy the invaders.

What is amazing about antibodies is how complex they are. The proteins in our body are incredibly complex. They are long chains that fold into unique shapes depending on hundreds of different types of chemical interactions. These are so complex that supercomputers can take literal years to figure out the shape of a single protein and how it folds depending on the subunits in its chain. This means that our immune system has to recognise these markers and figure out a complementary tag out of hundreds of billions of potential sequences. Antibodies have to be specific to their tag. If an antibody is produced that can target more than one tag, it can cause problems. If it targets a bacterial tag, but accidentally highlights the person’s cells as well, the immune system will start targeting and destroying the person’s organs. These auto-immune disorders can be devastating.

But when they work, antibodies are miraculous. They persist in the blood after an infection, and if a second infection occurs, memory cells in the blood can rapidly produce these antibodies before the infection can even produce symptoms. This is known as immunity, and is why we usually don’t get the same illness twice. Antibody based treatment is see as the future of medical therapy, and is something we will cover in future blogs.

PLASMA EXCHANGE

From population testing we can see that the majority of patients with COVID-19 recover, experiencing either mild symptoms, moderate symptoms requiring some form of treatment and hospitalisation, or no symptoms whatsoever. In these patients their immune system will have successfully recognised the virus and produced antibodies against it to neutralise the virus. It is the patients with severe symptoms, those in which the virus is running rampant in the body, that the production of antibodies happens too late.

Plasma exchange involves obtaining blood from patients who have beaten the virus, spinning the blood to separate out the red cells, white cells, platelets and watery plasma. The plasma contains all the glucose, small proteins and importantly for us, the antibodies. This plasma can be transfused into patients with COVID-19 that cannot cope, in order to help their immune system. These transfused antibodies will neutralise some of the viruses in the patient, reducing the viral load, amount of replication and cell destruction that causes such devastating symptoms in COVID-19.

The published editorial showed that in the most critical pneumonia patients, requiring mechanical ventilators and drugs to support the heart, mortality in plasma exchange patients resulted in a 47.8% mortality instead of 81.3%. Of course it is a single study with a limited number of patients, but the results are encouraging. It is further helped by the fact plasma exchange is a well established therapy, with established protocols known to intensivists and haematologists.

THE FUTURE

We may see the use of Plasma exchange for critically ill patients increase as the pandemic continues. It is not a treatment option available for everyone, as it requires intravenous access and careful monitoring in a controlled setting. But it also needs donation from people who have recovered from COVID and have suitable antibodies. So whilst it might not be a magic pill that everyone expects to cure COVID, it might be the difference between life and death for those that need it most.

Monthly Healthy Potluck at Health Hubs: Building Community Wellness in India

Monthly Healthy Potluck at Health Hubs: Building Community Wellness in India

Community-driven health initiatives are becoming an essential part of India’s preventive healthcare movement. While medical technology, AI diagnostics and digital screenings strengthen clinical care, lifestyle habits still remain the foundation of long-term wellness. One powerful but simple community practice gaining popularity is the Monthly Healthy Potluck at Health Hubs.

These potlucks promote healthier eating, strengthen social support systems, and bring people together to learn about nutrition and wellness in an enjoyable and accessible format. SecondMedic’s preventive health framework aligns perfectly with this model by integrating health education, nutrition insights and early-risk awareness into community activities.

This blog explores how monthly healthy potlucks are transforming health hubs across India and supporting preventive lifestyle habits at scale.

 

Why Community Wellness Matters in India

India is witnessing a steep rise in lifestyle-related illnesses.
According to the ICMR-NCD Burden Study:
• Over 100 million Indians live with diabetes
• Heart disease accounts for nearly 28% of all deaths
• Hypertension is becoming prevalent across younger age groups

Simultaneously, NFHS-5 data highlights increasing obesity, poor dietary diversity and rising sedentary behaviour. These challenges signal not just medical issues, but lifestyle gaps.

Community-based wellness initiatives provide the social support and collective learning required to bridge those gaps.

 

What Is a Monthly Healthy Potluck at Health Hubs?

A Monthly Healthy Potluck is a wellness event where:
• Participants bring nutritious homemade dishes
• Recipes focus on balance, low oil and whole ingredients
• Everyone eats together and shares food philosophy
• Health experts provide short preventive care sessions
• Participants learn simple, realistic lifestyle habits

This model transforms health hubs into interactive wellness environments instead of passive medical facilities.

 

Why Healthy Potlucks Work

1. They Make Healthy Eating Enjoyable

Healthy meals often feel restrictive when practiced alone. In a group setting, they become exciting because:
• People discover new recipes
• Participants try dishes they wouldn’t normally cook
• Food presentation inspires creativity
• Everyone learns portion control naturally

2. They Promote Social Accountability

When people cook, share and learn together, they form supportive communities that motivate consistent lifestyle changes.

3. They Strengthen Nutritional Awareness

Nutrition education becomes simpler when demonstrated through real food instead of lectures.

4. They Align with Preventive Healthcare

NITI Aayog’s Preventive Health & Wellness Report highlights behavioural change as a key driver of long-term health improvement. Potlucks encourage achievable, small lifestyle shifts.

 

Components of a Healthy Potluck at SecondMedic Health Hubs

1. Balanced Dish Contributions

Participants are encouraged to bring nutrient-dense dishes such as:
• Millet-based meals
• Vegetable-rich Indian curries
• Lean protein options
• Low-oil tiffin-style foods
• Fermented dishes
• Fruit bowls and salads

This ensures variety, balance and education through real examples.

2. Nutrition Spotlights

Health experts share quick insights on:
• Portion control
• Glycemic index
• Healthy cooking oils
• Hidden sugars
• Smart plate design
• Hydration science

These micro-education sessions empower participants to make better decisions at home.

3. Preventive Health Mini-Screenings

SecondMedic integrates:
• BMI checks
• Blood pressure assessments
• Sugar evaluations
• Quick fatigue and stress scoring

These screenings help individuals understand their health status while encouraging early intervention.

4. Recipe Exchange Corners

Participants document and exchange easy-to-cook healthy recipes. This fosters a culture of shared learning and innovation.

5. Wellness Activities

Events may include:
• 5-minute yoga routines
• Breathing exercises
• Mindfulness techniques
• Movement challenges

These fun micro-activities teach participants how to incorporate wellness effortlessly into daily routines.

 

How Healthy Potlucks Support India’s Preventive Health Movement

Encouraging Long-Term Dietary Shifts

When individuals repeatedly attend monthly events, their meal choices gradually transform. Consistency builds habits.

Reducing Fear Around Healthy Cooking

Seeing others prepare simple, tasty, low-oil dishes removes the stigma that healthy food is bland or difficult.

Strengthening Social Connectivity

Community bonds reduce stress, loneliness and isolation-factors known to weaken immunity and increase chronic disease risk.

Improving Health Literacy

Real-time demonstrations outperform written instructions. It becomes easier to understand nutrient density, fibre-rich meals and balanced plates when they are visually presented.

Supporting Digital Health Ecosystems

SecondMedic integrates event data into digital dashboards:
• Meal analysis
• Health scores
• Lifestyle tracking
• Preventive alerts

This combination of offline community activity and online tracking strengthens long-term adherence.

 

Example of a Healthy Potluck Spread

• Moong dal khichdi with vegetables
• Ragi roti with garlic chutney
• Grilled paneer salad
• Millet upma
• Fruit and nut platter
• Sprout chaat with lemon
• Buttermilk infused with mint

These items are affordable, accessible and easy to prepare-ideal for the Indian lifestyle.

 

Conclusion

Monthly Healthy Potlucks at Health Hubs offer a simple yet powerful model for promoting preventive healthcare in India. These events blend nutrition, social bonding, lifestyle learning and community-led motivation. They encourage individuals to adopt healthier habits without pressure, restriction or complexity.

With SecondMedic’s integrated preventive care framework, these potlucks become more than social gatherings-they become catalysts for building healthier communities, improving dietary behaviour and supporting long-term wellness.
