Heading Into The Third Year Of The Pandemic, The US Blood Supply Is At A 10-Year Low


The blood supply in the U.S. is now at its lowest level in over a decade.

Many of the nation’s blood centers currently have only a one-day supply of some blood types in inventory. This is dangerous because blood transfusions are needed for many surgeries. Blood is also used in the treatment of diseases like sickle cell anemia and certain cancers – and is critical to help those who suffer injuries from accidents or disasters.

In January 2022, the American Red Cross declared its first-ever national blood crisis. A joint statement by the American Hospital Association, the American Medical Association and the American Nurses Association said that the “severity and duration of this shortage could significantly jeopardize the ability of health care providers to meet the many urgent needs of our patients and communities.”

A consistent supply of blood is essential to the nation’s health. Blood is a precious lifesaving product that cannot be manufactured but must be donated. No substitute for blood exists.

Each day the U.S. needs about 29,000 units of red blood cells, 5,000 units of platelets and 6,500 units of plasma, according to the American Red Cross. The average blood transfusion is for three units, with a victim of a car accident requiring as many as 100. A single donation can help more than one patient. Convalescent plasma may even be used as a treatment against COVID-19, a possibility our team has been researching.

I am a professor and director of the Virtual Center for Supernetworks at the University of Massachusetts Amherst. My expertise is supply chains, including perishable product supply chains such as blood. The COVID-19 pandemic, heading into its third year, has exacerbated the challenges associated with the nation’s blood supply chains. Let me explain.

Two years of dramatic change

At the onset of the pandemic in the winter of 2020, with growing fear and uncertainty, blood collections at many schools and other sites that traditionally hosted mobile blood drives closed. Throughout the nation, elective surgeries were canceled and procedures to preserve blood put into place.

Even before the pandemic, blood service organizations faced many challenges – including economic ones – and the U.S. blood supply chain was going through major shifts. In pre-pandemic times, less than 10% of the U.S. population would donate blood in a given year, although 38% were eligible. Moreover, blood is perishable, with red blood cells lasting 42 days, and platelets only five days, so regular replenishment is essential.

But in the past two years, since the World Health Organization declared the COVID-19 pandemic, unforeseen ripple effects have resulted in an immense demand for blood. Many people delayed medical treatment and may now be suffering from more advanced disease. An increase in gun violence, drug overdoses, automobile accidents – some due to driving under the influence as a consequence of pandemic-induced stress and challenges – and other trauma during the pandemic have also led to escalating demand for blood.

The American Red Cross reports that since March 2020, blood donations have decreased by 10%, with a decrease of 62% in college and high school blood drives as many of those locations went remote. This age group represented about a quarter of all the donors in 2019, with a drop to about 10% of all donors during the pandemic.

Most recently, donors who have tested positive with the highly transmissible omicron variant have had to cancel scheduled appointments for donating blood. The U.S. Food and Drug Administration recently released guidelines with updated information for blood establishments regarding blood donations in the pandemic. Donating blood is itself safe and, importantly, according to the FDA, globally there have been “no reported cases of transfusion-transmitted coronavirus, including SARS-CoV-2.”

The American Red Cross provides about 40% of the blood and blood components that are needed in the U.S.. Donors can also donate blood at local community blood centers or hospitals, at Vitalant – formerly United Blood Services – or at member organizations of America’s Blood Centers. These make up North America’s largest network of nonprofit community blood centers and operate more than 600 blood donation collection sites.

 

Not just numbers

When it comes to blood shortages, people’s lives are on the line, and the stories are very personal.

A young pregnant mother in Louisiana who was suffering from COVID-19 and internal bleeding survived just long enough to see her newborn daughter, thanks to blood donations. An 11-year-old girl in West Virginia who is battling bone cancer has received 18 blood transfusions. An 8-year-old girl in Texas is suffering from T-cell leukemia and relies on blood donations, but numerous blood drives in her area were canceled. These are just a few examples.

And the ability to receive regular transfusions is a matter of life or death for those with certain illnesses.

The many links involved in blood supply

The blood supply chain is incredibly complex. It consists of the collection of donations, testing, processing and distribution, with ultimate transfusion to recipients at health care facilities. Along with “getting blood from donor to recipient,” ample supplies are needed for collection, testing and transfusion.

Less well recognized, but of immense importance, is the labor required in this supply chain, which, along with the donors, serves as the backbone. Throughout the pandemic, workers have been getting sick from COVID-19 and many have, sadly, lost their lives. The reduction in labor availability, along with decreases in productivity, have affected supply chains from food to health care.

With COVID-19 infection rates surging across the nation, blood collection services are also suffering from labor shortfalls, including of blood collection specialists. The Red Cross is reporting that staffing shortages in parts of the country are among the biggest hurdles now, with higher wages being offered in this health care sector to attract workers.

Easing restrictions – such as those on gay and bisexual men – could increase the availability of blood by about 2% to 4%. This is now being considered. As we approach the third year of the pandemic, the need for blood donations and for supporting this complex supply chain is even greater than at the onset of the pandemic.

Feeling Tired All The Time? Possible Causes And Solutions

Published

on

Long days of work, lack of sleep, and stress at the office can be the most common factors that make you feel tired. However, feeling “tired all the time” (TATT) without known reasons can be an indication of an underlying health issue that needs immediate attention.

Finding the exact cause of the lingering tiredness can be the first step toward solving the symptom.

Health conditions that cause fatigue:

1. Anemia – Anemia is one of the most common causes of fatigue. A person who has anemia does not have enough red blood cells in the body, causing symptoms such as tiredness, dizziness, feeling cold and crankiness.

Most often, anemia is caused by iron deficiency. Hence, the condition can be best resolved by including iron-rich foods in the diet and use of iron supplements.

2. Sleep Apnea – It causes the body to stop breathing momentarily during sleep. The condition can affect the quality of sleep and hence make you feel fatigued.

For milder cases of sleep apnea, lifestyle changes such as losing weight or quitting smoking can help solve the sleep disorder. In more severe cases where there is an obstruction in breathing, surgeries and therapies can help.

3. Diabetes – A person who has diabetes has changes in blood sugar level, which can cause fatigue. A patient who is already on diabetic medication can also experience tiredness as a side effect of the medication.

Early identification and taking the correct treatment is the key to managing diabetes. Losing extra weight and having a healthy diet also help in the treatment.

4. Thyroid – Thyroid diseases can be due to an overactive or an underactive thyroid gland. In people who have an underactive thyroid (hypothyroidism), the metabolism slows down leading to symptoms such as lethargy and fatigue. In people with an overactive thyroid (hyperthyroidism), the metabolism speeds up leading to fatigue and difficulty sleeping.

Right diet and lifestyle choices, along with medications, can help in thyroid management.

5. Infections – A person can show symptoms of fatigue when the body is fighting a viral or bacterial infection. Infections ranging from the flu to HIV can cause tiredness.

Along with fatigue, other symptoms such as fever, headache, body aches, shortness of breath and appetite loss can also accompany the infection. Treating the symptoms and taking adequate rest helps in faster recovery.

6. Food allergies – Fatigue may be an early warning sign of hidden food allergies and autoimmune disorders such as celiac disease. Identifying the allergen using a food allergy test or through an elimination diet can help in allergy treatment.

7. Heart disease – If you feel exhausted from an activity that used to be easy, then it is good to check your heart health, as fatigue can be an indication of underlying heart disease.

8. Depression/ anxiety – Fatigue can also be an indicator of a mental health disorder such as depression or anxiety. A combination of medication and psychotherapy can help relieve symptoms.

Lifestyle causes

Apart from serious health conditions, certain lifestyle habits such as dehydration, poor diet, stress and insufficient sleep can cause exhaustion. Having a well-balanced diet, regular exercise and routine sleep can help solve fatigue caused by lifestyle habits.

How To Overcome Your Sleep Debt And Reclaim Energy

Published

Picture this: you’re burning the midnight oil, studying or binge-watching your favorite shows, all at the expense of a good night’s sleep. Have you ever stopped to think about the toll it takes on your body and mind? The consequences can be more serious than you might realize.

Not getting enough sleep can translate into a multitude of issues, including weight gain, lack of focus, tiredness, a haze of confusion, and even depression. If you too are encountering similar issues lately then chances are you have a sleep debt.

Wondering what is sleep debt?

People from 13-18 years of age need 8 hours of sleep, whilst adults beyond that age will require at least 7 hours of snooze.

Sleep debt is a collection of the total hours you haven’t slept or traded your sleep for something else. Sleep debt keeps piling up as a person falls short of the total hours of sleep recommended for an adult, according to the Centers for Disease Control and Prevention.

And when you keep letting go of your sleep for other activities, the body adapts to the new normal and effects start to reflect on the energy levels, which deplete.

“However, like every other debt out there, this too has a repayment option,” Dr. Kunal Kumar, medical director of the Sleep Center at Einstein Medical Center in Philadelphia, told Livestrong.

Just like financial debt, imagine sleep debt as a debt you owe to your body. It needs to be repaid. The good news is that catching up on sleep is indeed possible.

  • Maintain a set sleep schedule: Overhauling the sleep schedule is a pretty difficult task to achieve, and it’s best to do that gradually. Create a set sleep schedule by making some small changes to your routine. Instead of making abrupt shifts in your bedtime or wake-up time, adjust them gradually by 15 to 30-minute increments.
  • Minimize your gadget usage: Wind down activities and minimize electronic usage before bed to promote better sleep. Relax and prepare for quality sleep by dimming the lights and setting an alarm for 30 minutes to an hour before bed.
  • Reshuffle your sleeping arrangements: Are you finding it hard to get a good night’s sleep due to excessive sweating? Well, here’s a handy solution: consider upgrading to a cooling mattress or opting for cooling sheets. These innovative sleep essentials can help regulate your body temperature, and keep you comfortably cool throughout the night, ensuring a more blissful slumber. Memory foam pillows can work wonders in relieving neck and back discomfort in case you are struggling with backache.
  • Improve the bedroom environment: Create a sleep-friendly bedroom environment by adjusting the temperature for comfort, and blocking out disruptive lights, or noises that might disturb your restful slumber. And if your mattress, pillow, or sheets are worn out or no longer providing the support you need, consider treating yourself to new ones.

Omega-3 Fatty Acids Slow The Progression Of Amyotrophic Lateral Sclerosis: Study

Published

on

Omega-3 fatty acids are known for a range of health benefits, from promoting brain and heart health to reducing inflammation and protection against several chronic conditions.

In a new study, researchers found that omega-3 acids, especially the type found in foods like flaxseeds, walnuts, chia seeds, canola oil and soybean oil, can slow down the progression of amyotrophic lateral sclerosis (ALS).

It is a debilitating nervous system disease that gradually worsens over time and can be fatal. The condition results in a loss of muscle control and affects the nerve cells in the brain and spinal cord. It is also known as Lou Gehrig’s disease after the baseball player who was diagnosed with it.

The initial symptoms of the disease include muscle weakness, difficulty in walking and hand movements. The symptoms can slowly progress to difficulties with chewing, swallowing, speaking and breathing.

The exact cause of ALS is not known. However, around 10% of people get it from a risk gene passed down from a family member. It is estimated that more than 32,000 people in the U.S. live with the condition.

In the latest study, researchers from Harvard T.H. Chan School of Public Health in Massachusetts evaluated 449 people living with ALS in a clinical trial. The team assessed the severity of their symptoms, the progression of their disease, along with the levels of omega-3 fatty acids in their blood, for 18 months.

The study suggested that alpha-linolenic acid (ALA), a type of omega-3 found in plants, is particularly beneficial in slowing the progression of ALS. The participants with the highest levels of ALA had a 50% reduced risk of death during the study period compared to those with the lowest levels of ALA.

Researchers also found a reduction in death risk in participants who had eicosapentaenoic acid, the type of omega-3 fatty acid found in fatty fish and fish oil, and linoleic acid found in vegetable oils, nuts and seeds.

A previous study conducted by the same team suggested that a diet high in ALA and higher blood levels of the nutrient could reduce the risk of developing the condition.

“In this study, we found that among people living with ALS, higher blood levels of ALA were also associated with a slower disease progression and a lower risk of death within the study period. These findings, along with our previous research suggest that this fatty acid may have neuroprotective effects that could benefit people with ALS,” said Kjetil Bjornevik, the lead author of the study.
