COVID-19 Lambda Variant Could Be ‘Most Dangerous’ But Chinese Experts Are Not Worried


The lambda variant has certain traits that could make it the “most dangerous” strain of SARS-CoV-2, the virus responsible for COVID-19, but Chinese experts are not worried. Here’s why. 

Delta Variant Reaches Japan

Japan’s health ministry officials announced on Friday that they have found their first lambda case in the country — a woman in her 30s who arrived at Haneda Airport on July 20 after taking a flight from Peru, the reported place of origin of the variant. 

The woman had tested positive for the novel coronavirus at the airport despite not showing symptoms. Her samples were taken to the National Institute of Infectious Diseases, and the facility was the one to confirm that she had the delta variant, according to the Japan Times

The news has since been met with fear and anxiety as countries in the Asia-Pacific region are currently grappling with the surge in cases brought about by the delta variant. The appearance of the lambda variant in the region also poses the risk of having more economic problems as scientists from different parts of the world have claimed the new strain to potentially be the most dangerous among the newer variants. 

What Makes Delta Very Dangerous

In a study published on the bioRxiv server, a team of scientists used molecular phylogenetic analysis to better understand the lambda variant. The researchers were able to establish the two distinct traits of the lambda variant that are making it more virulent than other strains. First, the lambda variant is resistant to viral-induced immune responses (such as the case in vaccinations). Next, it has two mutations that enhance its rate of transmission. 

The findings of the study corroborate previous studies that have determined the higher infectivity of the lambda, delta and epsilon variants, as all three have the L452Q/R mutation. The delta variant, which was first identified in India, is the one that is currently wreaking havoc in many parts of the world. On the other hand, the epsilon variant, which was first detected in California, is the one that is predominantly spreading in Pakistan, as per NJ.com

While the World Health Organization has designated the delta variant as a “variant of concern,” it has given a lower designation to the lambda variant by classifying it as a “variant of interest.” Nevertheless, experts have indicated that the lambda variant is quite capable of causing an epidemic, according to News-Medical.Net

“I think any time a variant is identified and demonstrates the capacity to rapidly spread in a population, you have to be concerned,” Dr. Gregory Poland, director of the Vaccine Research Group at the Mayo Clinic in Rochester, Minnesota, told CNN recently. “The question is, do those mutations give the virus some sort of advantage, which of course is to human disadvantage? The answer in lambda is yes.”

What Chinese Experts Are Saying

Despite the concerns over the newer strains, especially the lambda variant, Chinese experts are not worried. According to them, the vaccines produced by China-based manufacturers are still effective against the lambda variant. They also theorized that while the strain caused a spike in cases in Southern America and in other places in the Southern Hemisphere, the variant won’t be able to proliferate easily in countries found in the Northern Hemisphere. 

Zhuang Shilihe, an expert based in China’s Guangzhou City, told the Global Times that the latest scientific studies in South American countries, such as Chile and Peru, have shown that the vaccines deployed by Chinese manufacturers are still effective against the lambda variant. Shilihe even pointed out that the percentage of new cases caused by the lambda variant in such places is already declining. 

Another Beijing-based expert who spoke with the Global Times on condition of anonymity maintained that the lambda variant is unlikely to dominate in Japan and other countries in the Northern Hemisphere as these places are currently experiencing the summer season, and the temperatures there are not suitable for the transmission of the new variant, which was first identified in the Southern Hemisphere.

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

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.
