Many have woken up to India’s plastic waste generation problem after worrying data was presented in Parliament. But alarm bells have been ringing for a long time. According to the Centre, plastic waste generation has more than doubled in the last five years, with an average annual increase of 21.8%. A 2018-2019 Central Pollution Control Board (CPCB) report puts India’s annual plastic waste generation at 3.3 million metric tonnes. This, according to experts, is an underestimation. Seven states — Maharashtra, Delhi, Karnataka, Uttar Pradesh, Gujarat, West Bengal, and Tamil Nadu — contribute to 66% of the country’s total plastic generation. And, Goa and Delhi’s per capita plastic use is six times higher than the national average. A 2018 study by IIT Kharagpur found that 49% of waste in Delhi drains was plastic.
There is need for robust national plan, ensure transparency and to involve every stakeholder- from Government and industries to every last citizen.
New Delhi [India], February 18 (ANI): Taking forward the commitment to eliminate single-use plastics, the Environment Ministry has notified comprehensive guidelines on Extended Producer Responsibility (EPR) for plastic packaging under Plastic Waste Management Rules, 2016.
According to the Ministry of Environment, Forest and Climate Change, the guidelines on extended producer responsibility coupled with the prohibition of identified single-use plastic items, which have low utility and high littering potential, with effect from July 1, 2022, are important steps for reducing pollution caused by littered plastic waste in the country.
The minister said that the guidelines provide a framework to strengthen the circular economy of plastic packaging waste, promote the development of new alternatives to plastics and provide further next steps for moving towards sustainable plastic packaging by businesses. “Reuse of rigid plastic packaging material has been mandated in the guidelines to reduce the use of fresh plastic material for packaging,” Yadav said.
The Ministry said that the enforceable prescription of a minimum level of recycling of plastic packaging waste collected under EPR along with the use of recycled plastic content will further reduce plastic consumption and support the recycling of plastic packaging waste.
The EPR guidelines will give a boost for formalization and further development of the plastic waste management sector. As a significant first, the guidelines allow for the sale and purchase of surplus extended producer responsibility certificates, thus setting up a market mechanism for plastic waste management.
“The implementation of EPR will be done through a customized online platform which will act as the digital backbone of the system. The online platform will allow tracking and monitoring of EPR obligations and reduce the compliance burden for companies through online registration and filing of annual returns. In order to ensure monitoring on fulfilment of EPR obligations, the guidelines have prescribed a system of verification and audit of enterprises,” it said.
The guidelines prescribe a framework for the levy of environmental compensation based upon the polluter pays principle, with respect to non-fulfilment of extended producer responsibility targets by producers, importers and brand owners, for the purpose of protecting and improving the quality of the environment and preventing, controlling and abating environment pollution, the Ministry added.
It further said that the funds collected shall be utilized for collection, recycling and end of life disposal of uncollected plastic waste in an environmentally sound manner.
Under these producers, importers and brand owners may operate schemes such as deposit-refund system or buy-back or any other model in order to prevent the mixing of plastic packaging waste with solid waste. (ANI)
NEW DELHI: Has the Covid-19 pandemic worsened addiction to the internet among children? The footfall at psychiatric out-patient departments in hospitals, especially those offering help to kids hooked to the net, be it for online gaming, chatting with friends or sharing videos, offers a glimpse of the problem. At AIIMS, the number of parents seeking help for their children, among them the most being those addicted to online gaming, has increased significantly after the pandemic. The special clinic was inundated with requests from parents seeking help, nearly 80% of them are related to online gaming, 15% about excessive use of social media and the remaining 5% related to problems like pornography”.
The parents of a Class XI student — name withheld on request — approached AIIMS because their son was gaming online for hours, and wasn’t willing to give up the habit. The son even hit his father when the latter tried to take away the laptop. In another case, a Class IX student hooked to online gambling spent Rs 75,000 in a single week on his parent’s credit card. Children have developed mental and emotional issues due to addiction to online streaming services. The girl would stay awake all night to finish the TV series and sleep during the day. It continued for six to seven months. She developed insomnia and began hallucinating, which is when the parents panicked and brought her to hospital. We had to put her on psychiatric medications and counselling. During the pandemic, however, the problem increased multiple times. The schools were closed and classes were being held online. This increased the children’s access to digital technologies. Secondly, social interactions shifted online due to restricted physical movement forced by Covid. They Spend more time online led to the addiction. As for online gaming, doctors said these activities were designed to attract young people and were addictive in nature. Online gaming causes the same kind of craving and withdrawal that you see with any other addiction such as substance abuse.
What is the solution to this? Internet use is one of the important pillars of learning and growth in today’s time and, therefore, it may not be advisable to prevent school children from using it. It may be prudent to promote safe usage of the internet. Very importantly, parents should be aware of the warning signs in their children, for example behavioural changes, reduced interaction with family members, children spending most of their time in their rooms, irregular sleeping or eating habits and mood changes that may signal troublesome usage of the technologies. If the habit persists and worsens, it may be advisable to seek expert help. The problem of internet addiction isn’t limited to children belonging to particular social strata, the doctors said. “We need to have more cyber addiction clinics in government hospitals so even those who cannot afford private treatment can seek timely help,” said one senior medico. “It can help prevent serious mental health issues in children and even save lives.” The doctor added that most children suffering from internet addiction improved with behavioural therapy and counselling. It was only in rare cases that medical management became necessary, he added.
Asthma is a major noncommunicable disease (NCD), affecting both children and adults.
Inflammation and narrowing of the small airways in the lungs cause asthma symptoms, which can be any combination of cough, wheeze, shortness of breath and chest tightness.
Asthma affected an estimated 262 million people in 2019 and caused 461000 deaths.
Asthma is the most common chronic disease among children.
Inhaled medication can control asthma symptoms and allow people with asthma to lead a normal, active life.
Avoiding asthma triggers can also help to reduce asthma symptoms.
Most asthma-related deaths occur in low- and lower-middle income countries, where under-diagnosis and under-treatment is a challenge.
What is asthma?
Asthma is a long-term condition affecting children and adults. The air passages in the lungs become narrow due to inflammation and tightening of the muscles around the small airways. This causes asthma symptoms: cough, wheeze, shortness of breath and chest tightness. These symptoms are intermittent and are often worse at night or during exercise. Other common “triggers” can make asthma symptoms worse. Triggers vary from person to person, but can include viral infections (colds), dust, smoke, fumes, changes in the weather, grass and tree pollen, animal fur and feathers, strong soaps, and perfume.
The impact of asthma on daily life
Asthma is often under-diagnosed and under-treated, particularly in low- and middle-income countries.
People with under-treated asthma can suffer sleep disturbance, tiredness during the day, and poor concentration. Asthma sufferers and their families may miss school and work, with financial impact on the family and wider community. If symptoms are severe, people with asthma may need to receive emergency health care and they may be admitted to hospital for treatment and monitoring. In the most severe cases, asthma can lead to death.
Causes of asthma
Many different factors have been linked to an increased risk of developing asthma, although it is often difficult to find a single, direct cause.
Asthma is more likely if other family members also have asthma – particularly a close relative, such as a parent or sibling.
Asthma is more likely in people who have other allergic conditions, such as eczema and rhinitis (hay fever).
Urbanisation is associated with increased asthma prevalence, probably due to multiple lifestyle factors.
Events in early life affect the developing lungs and can increase the risk of asthma. These include low-birth weight, prematurity, exposure to tobacco smoke and other sources of air pollution, as well as viral respiratory infections.
Exposure to a range of environmental allergens and irritants are also thought to increase the risk of asthma, including indoor and outdoor air pollution, house dust mites, moulds, and occupational exposure to chemicals, fumes, or dust.
Children and adults who are overweight or obese are at a greater risk of asthma.
Reducing the burden of asthma
Asthma cannot be cured, but good management with inhaled medications can control the disease and enable people with asthma to enjoy a normal, active life.
There are two main types of inhaler:
bronchodilators (such as salbutamol), that open the air passages and relieve symptoms; and
steroids (such as beclometasone), that reduce inflammation in the air passages. This improves asthma symptoms and reduces the risk of severe asthma attacks and death.
People with asthma may need to use their inhaler every day. Their treatment will depend on the frequency of symptoms and the different types of inhalers available.
It can be difficult to coordinate breathing using an inhaler – especially for children and during emergency situations. Using a “spacer” device makes it easier to use an aerosol inhaler and helps the medicine to reach the lungs more effectively. A spacer is a plastic container with a mouthpiece or mask at one end, and a hole for the inhaler in the other. A homemade spacer, made from a 500-ml plastic bottle, can be as effective as a commercially-manufactured inhaler.
People with asthma and their families need education to understand more about their asthma, their treatment, triggers to avoid, and how to manage their symptoms at home. It is also important to raise community awareness, to reduce the myths and stigma associated with asthma in some settings.
In an era, when even licensed and qualified doctors are finding it difficult to practice medicine, it is strange that unqualified and unlicensed are having a field day. Why strict regulations do not apply to them, is beyond any reasoning and logic. If a medical facility or clinic is functional, it is difficult for the patient, especially in emergency, to check or even doubt its credentials. How such facilities are open, functional and thriving. Sadly our regulation is trying to regulate, who are already regulated. It is trying to punish those who are qualified and licensed, but turns a blind eye towards unlicensed and unqualified doctors.
Such fake doctors own medical set ups, may conduct surgeries, sometimes run hospitals with little help from qualified doctors and do procedures. Another problem is that they promote fake rumours about genuinely qualified doctors and create a mist of mistrust to propagate their fake medical business.
The glans of an infant’s penis shrivelled and fell off after a quack tied a horse’s hair around it ‘to prevent bleeding’ after a ritual of circumcision. The child was rushed to hospital, where a surgery was performed to ensure that the baby will be able to urinate normally, but the boy has lost his glans.. A quack had conducted the religious ritual of circumcision on November 22, 2021, and tied a horse hair to the child’s penis. He then bandaged it and told the family to go home.
The child was born in October 2021. Ten days later, the family members noticed that the glans had come off along with the dressing. Families choose to get their male infants circumcised by neighbourhood quacks. This is not just unhygienic, but can lead to major complications as well. Other unhealthy practices like sprinkling ash on the wound after circumcision are also prevalent.
A toddler has died and his baby brother has required life-saving surgery in hospital after a medical procedure, understood to have been a circumcision, went horribly wrong in Perth’s south-east. The brothers were rushed to hospital in Armadale by family Tuesday evening following the surgeries. The West Australian reports a two-year-old boy was pronounced dead at the hospital’s emergency department. His infant brother – aged between seven and eight months – was rushed to Perth Children’s Hospital for emergency surgery.7NEWS reports he has since been discharged from hospital. WA Police have confirmed the toddler’s death is not being treated as suspicious. “It can be confirmed the boy underwent a medical procedure at a registered medical centre prior to his death,” a police spokeswoman said.
Circumcisionis one of the oldest surgical procedures and one of the most commonly performed surgical procedures in practice today. Descriptions of ritual circumcision span across cultures, and have been described in ancient Egyptian texts as well as the Old Testament. In the United States, circumcision is a commonly performed procedure. It is a relatively safe procedure with a low overall complication rate. Most complications are minor and can be managed easily. Though uncommon, complications of circumcision do represent a significant percentage of cases seen by paediatric urologists. Often they require surgical correction that results in a significant cost to the health care system. Severe complications are quite rare, but death has been reported as a result in some cases. A thorough and complete preoperative evaluation, focusing on bleeding history and birth history, is imperative. Proper selection of patients based on age and anatomic considerations as well as proper sterile surgical technique are critical to prevent future circumcision-related adverse events.
Symptoms of type 1 diabetes often appear suddenly and are often the reason for checking blood sugar levels. Because symptoms of other types of diabetes and prediabetes come on more gradually or may not be evident, the American Diabetes Association (ADA) has recommended screening guidelines. The ADA recommends that the following people be screened for diabetes:
Anyone with a body mass index higher than 25 (23 for Asian Americans), regardless of age, who has additional risk factors, such as high blood pressure, abnormal cholesterol levels, a sedentary lifestyle, a history of polycystic ovary syndrome or heart disease, and who has a close relative with diabetes.
Anyone older than age 45 is advised to receive an initial blood sugar screening, and then, if the results are normal, to be screened every three years thereafter.
Women who have had gestational diabetes are advised to be screened for diabetes every three years.
Anyone who has been diagnosed with prediabetes is advised to be tested every year.
Tests for type 1 and type 2 diabetes and prediabetes
Glycated hemoglobin (A1C) test. This blood test, which doesn’t require fasting, indicates your average blood sugar level for the past two to three months. It measures the percentage of blood sugar attached to hemoglobin, the oxygen-carrying protein in red blood cells.
The higher your blood sugar levels, the more hemoglobin you’ll have with sugar attached. An A1C level of 6.5% or higher on two separate tests indicates that you have diabetes. An A1C between 5.7 and 6.4 % indicates prediabetes. Below 5.7 is considered normal.
If the A1C test results aren’t consistent, the test isn’t available, or you have certain conditions that can make the A1C test inaccurate — such as if you are pregnant or have an uncommon form of hemoglobin (known as a hemoglobin variant) — your doctor may use the following tests to diagnose diabetes:
Random blood sugar test. A blood sample will be taken at a random time. Regardless of when you last ate, a blood sugar level of 200 milligrams per deciliter (mg/dL) — 11.1 millimoles per liter (mmol/L) — or higher suggests diabetes.
Fasting blood sugar test. A blood sample will be taken after an overnight fast. A fasting blood sugar level less than 100 mg/dL (5.6 mmol/L) is normal. A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is considered prediabetes. If it’s 126 mg/dL (7 mmol/L) or higher on two separate tests, you have diabetes.
Oral glucose tolerance test. For this test, you fast overnight, and the fasting blood sugar level is measured. Then you drink a sugary liquid, and blood sugar levels are tested periodically for the next two hours.
A blood sugar level less than 140 mg/dL (7.8 mmol/L) is normal. A reading of more than 200 mg/dL (11.1 mmol/L) after two hours indicates diabetes. A reading between 140 and 199 mg/dL (7.8 mmol/L and 11.0 mmol/L) indicates prediabetes.
If type 1 diabetes is suspected, your urine will be tested to look for the presence of a byproduct produced when muscle and fat tissue are used for energy because the body doesn’t have enough insulin to use the available glucose (ketones). Your doctor will also likely run a test to see if you have the destructive immune system cells associated with type 1 diabetes called autoantibodies.
Tests for gestational diabetes
Your doctor will likely evaluate your risk factors for gestational diabetes early in your pregnancy:
If you’re at high risk of gestational diabetes — for example, if you were obese at the start of your pregnancy; you had gestational diabetes during a previous pregnancy; or you have a mother, father, sibling or child with diabetes — your doctor may test for diabetes at your first prenatal visit.
If you’re at average risk of gestational diabetes, you’ll likely have a screening test for gestational diabetes sometime during your second trimester — typically between 24 and 28 weeks of pregnancy.
Your doctor may use the following screening tests:
Initial glucose challenge test. You’ll begin the glucose challenge test by drinking a syrupy glucose solution. One hour later, you’ll have a blood test to measure your blood sugar level. A blood sugar level below 140 mg/dL (7.8 mmol/L) is usually considered normal on a glucose challenge test, although this may vary at specific clinics or labs.
If your blood sugar level is higher than normal, it only means you have a higher risk of gestational diabetes. Your doctor will order a follow-up test to determine if you have gestational diabetes.
Follow-up glucose tolerance testing. For the follow-up test, you’ll be asked to fast overnight and then have your fasting blood sugar level measured. Then you’ll drink another sweet solution — this one containing a higher concentration of glucose — and your blood sugar level will be checked every hour for a period of three hours.
If at least two of the blood sugar readings are higher than the normal values established for each of the three hours of the test, you’ll be diagnosed with gestational diabetes.
Depending on what type of diabetes you have, blood sugar monitoring, insulin and oral medications may play a role in your treatment. Eating a healthy diet, maintaining a healthy weight and participating in regular activity also are important factors in managing diabetes.
Treatments for all types of diabetes
An important part of managing diabetes — as well as your overall health — is maintaining a healthy weight through a healthy diet and exercise plan:
Healthy eating. Contrary to popular perception, there’s no specific diabetes diet. You’ll need to center your diet on more fruits, vegetables, lean proteins and whole grains — foods that are high in nutrition and fiber and low in fat and calories — and cut down on saturated fats, refined carbohydrates and sweets. In fact, it’s the best eating plan for the entire family. Sugary foods are OK once in a while, as long as they’re counted as part of your meal plan.
Yet, understanding what and how much to eat can be a challenge. A registered dietitian can help you create a meal plan that fits your health goals, food preferences and lifestyle. This will likely include carbohydrate counting, especially if you have type 1 diabetes or use insulin as part of your treatment.
Physical activity. Everyone needs regular aerobic exercise, and people who have diabetes are no exception. Exercise lowers your blood sugar level by moving sugar into your cells, where it’s used for energy. Exercise also increases your sensitivity to insulin, which means your body needs less insulin to transport sugar to your cells.
Get your doctor’s OK to exercise. Then choose activities you enjoy, such as walking, swimming or biking. What’s most important is making physical activity part of your daily routine.
Aim for at least 30 minutes or more of aerobic exercise most days of the week, or at least 150 minutes of moderate physical activity a week. Bouts of activity can be as brief as 10 minutes, three times a day. If you haven’t been active for a while, start slowly and build up gradually. It’s also a good idea to avoid sitting for too long — aim to get up and move if you’ve been sitting for more than 30 minutes.
Treatments for type 1 and type 2 diabetes
Treatment for type 1 diabetes involves insulin injections or the use of an insulin pump, frequent blood sugar checks, and carbohydrate counting. Treatment of type 2 diabetes primarily involves lifestyle changes, monitoring of your blood sugar, along with diabetes medications, insulin or both.
Monitoring your blood sugar. Depending on your treatment plan, you may check and record your blood sugar as many as four times a day or more often if you’re taking insulin. Careful monitoring is the only way to make sure that your blood sugar level remains within your target range. People with type 2 diabetes who aren’t taking insulin generally check their blood sugar much less frequently.
People who receive insulin therapy also may choose to monitor their blood sugar levels with a continuous glucose monitor. Although this technology hasn’t yet completely replaced the glucose meter, it can significantly reduce the number of fingersticks necessary to check blood sugar and provide important information about trends in blood sugar levels.
Even with careful management, blood sugar levels can sometimes change unpredictably. With help from your diabetes treatment team, you’ll learn how your blood sugar level changes in response to food, physical activity, medications, illness, alcohol, stress — and for women, fluctuations in hormone levels.
In addition to daily blood sugar monitoring, your doctor will likely recommend regular A1C testing to measure your average blood sugar level for the past two to three months.
Compared with repeated daily blood sugar tests, A1C testing better indicates how well your diabetes treatment plan is working overall. An elevated A1C level may signal the need for a change in your oral medication, insulin regimen or meal plan.
Your target A1C goal may vary depending on your age and various other factors, such as other medical conditions you may have. However, for most people with diabetes, the American Diabetes Association recommends an A1C of below 7%. Ask your doctor what your A1C target is.
Insulin. People with type 1 diabetes need insulin therapy to survive. Many people with type 2 diabetes or gestational diabetes also need insulin therapy.
Many types of insulin are available, including short-acting (regular insulin), rapid-acting insulin, long-acting insulin and intermediate options. Depending on your needs, your doctor may prescribe a mixture of insulin types to use throughout the day and night.
Insulin can’t be taken orally to lower blood sugar because stomach enzymes interfere with insulin’s action. Often insulin is injected using a fine needle and syringe or an insulin pen — a device that looks like a large ink pen.
An insulin pump also may be an option. The pump is a device about the size of a small cellphone worn on the outside of your body. A tube connects the reservoir of insulin to a catheter that’s inserted under the skin of your abdomen.
A tubeless pump that works wirelessly is also now available. You program an insulin pump to dispense specific amounts of insulin. It can be adjusted to deliver more or less insulin depending on meals, activity level and blood sugar level.
In September 2016, the Food and Drug Administration approved the first artificial pancreas for people with type 1 diabetes who are age 14 and older. A second artificial pancreas was approved in December 2019. Since then systems have been approved for children older than 2 years old.
An artificial pancreas is also called closed-loop insulin delivery. The implanted device links a continuous glucose monitor, which checks blood sugar levels every five minutes, to an insulin pump. The device automatically delivers the correct amount of insulin when the monitor indicates it’s needed.
There are more artificial pancreas (closed loop) systems currently in clinical trials.
Oral or other medications. Sometimes other oral or injected medications are prescribed as well. Some diabetes medications stimulate your pancreas to produce and release more insulin. Others inhibit the production and release of glucose from your liver, which means you need less insulin to transport sugar into your cells.
Still others block the action of stomach or intestinal enzymes that break down carbohydrates or make your tissues more sensitive to insulin. Metformin (Glumetza, Fortamet, others) is generally the first medication prescribed for type 2 diabetes.
Another class of medication called SGLT2 inhibitors may be used. They work by preventing the kidneys from reabsorbing sugar into the blood. Instead, the sugar is excreted in the urine.
Transplantation. In some people who have type 1 diabetes, a pancreas transplant may be an option. Islet transplants are being studied as well. With a successful pancreas transplant, you would no longer need insulin therapy.
But transplants aren’t always successful — and these procedures pose serious risks. You need a lifetime of immune-suppressing drugs to prevent organ rejection. These drugs can have serious side effects, which is why transplants are usually reserved for people whose diabetes can’t be controlled or those who also need a kidney transplant.
Bariatric surgery. Although it is not specifically considered a treatment for type 2 diabetes, people with type 2 diabetes who are obese and have a body mass index higher than 35 may benefit from this type of surgery. People who’ve undergone gastric bypass have seen significant improvements in their blood sugar levels. However, this procedure’s long-term risks and benefits for type 2 diabetes aren’t yet known.
Treatment for gestational diabetes
Controlling your blood sugar level is essential to keeping your baby healthy and avoiding complications during delivery. In addition to maintaining a healthy diet and exercising, your treatment plan may include monitoring your blood sugar and, in some cases, using insulin or oral medications.
Your doctor also will monitor your blood sugar level during labor. If your blood sugar rises, your baby may release high levels of insulin — which can lead to low blood sugar right after birth.
Treatment for prediabetes
If you have prediabetes, healthy lifestyle choices can help you bring your blood sugar level back to normal or at least keep it from rising toward the levels seen in type 2 diabetes. Maintaining a healthy weight through exercise and healthy eating can help. Exercising at least 150 minutes a week and losing about 7% of your body weight may prevent or delay type 2 diabetes.
Sometimes medications — such as metformin (Glucophage, Glumetza, others) — also are an option if you’re at high risk of diabetes, including when your prediabetes is worsening or if you have cardiovascular disease, fatty liver disease or polycystic ovary syndrome.
In other cases, medications to control cholesterol — statins, in particular — and high blood pressure medications are needed. Your doctor might prescribe low-dose aspirin therapy to help prevent cardiovascular disease if you’re at high risk. However, healthy lifestyle choices remain key.
Signs of trouble in any type of diabetes
Because so many factors can affect your blood sugar, problems may sometimes arise that require immediate care, such as:
High blood sugar (hyperglycemia). Your blood sugar level can rise for many reasons, including eating too much, being sick or not taking enough glucose-lowering medication. Check your blood sugar level as directed by your doctor, and watch for signs and symptoms of high blood sugar — frequent urination, increased thirst, dry mouth, blurred vision, fatigue and nausea. If you have hyperglycemia, you’ll need to adjust your meal plan, medications or both.
Increased ketones in your urine (diabetic ketoacidosis). If your cells are starved for energy, your body may begin to break down fat. This produces toxic acids known as ketones. Watch for loss of appetite, weakness, vomiting, fever, stomach pain and a sweet, fruity breath.
You can check your urine for excess ketones with an over-the-counter ketones test kit. If you have excess ketones in your urine, consult your doctor right away or seek emergency care. This condition is more common in people with type 1 diabetes.
Hyperglycemic hyperosmolar nonketotic syndrome. Signs and symptoms of this life-threatening condition include a blood sugar reading over 600 mg/dL (33.3 mmol/L), dry mouth, extreme thirst, fever, drowsiness, confusion, vision loss and hallucinations. Hyperosmolar syndrome is caused by sky-high blood sugar that turns blood thick and syrupy.
It is seen in people with type 2 diabetes, and it’s often preceded by an illness. Call your doctor or seek immediate medical care if you have signs or symptoms of this condition.
Low blood sugar (hypoglycemia). If your blood sugar level drops below your target range, it’s known as low blood sugar (hypoglycemia). If you’re taking medication that lowers your blood sugar, including insulin, your blood sugar level can drop for many reasons, including skipping a meal and getting more physical activity than normal. Low blood sugar also occurs if you take too much insulin or an excess of a glucose-lowering medication that promotes the secretion of insulin by your pancreas.
Check your blood sugar level regularly, and watch for signs and symptoms of low blood sugar — sweating, shakiness, weakness, hunger, dizziness, headache, blurred vision, heart palpitations, irritability, slurred speech, drowsiness, confusion, fainting and seizures. Low blood sugar is treated with quickly absorbed carbohydrates, such as fruit juice or glucose tablets.

Social media has helped people communicate more and instantly. The use of social media among children has increased tremendously. But without doubt, it has great addictive potential and one such case as mentioned is reflecting just the tip of the iceberg. The side effects can be manifold, like psychiatric illness, loss of education, disconnection from the reality and loss of time are only a few, which are evident.
The complaint, filed by Tammy Rodriguez in San Francisco federal court earlier this week, claims Selena Rodriguez suffered from depression, sleep deprivation, eating disorders, and self-harm tied to her use of Instagram and Snapchat.
According to the filing, Selena began using social media roughly two years before her death by suicide in July 2021, during which time she developed “an extreme addiction to Instagram and Snapchat.” The filing also claims the 11-year-old missed school multiple times because of her social media use and that she was asked to send sexually explicit content by male users on both platforms.
Rodriguez wrote in the filing that she attempted to get her daughter mental health treatment several times, with one outpatient therapist saying she had “never seen a patient as addicted to social media as Selena.” At one point, Selena was hospitalized for emergency psychiatric care, according to the complaint.
In a statement, Snap said it couldn’t comment on the specifics of an active case but told Insider “nothing is more important to us than the wellbeing of our community.”
“We are devastated to hear of Selena’s passing and our hearts go out to her family,” a Snap spokesperson told Insider. “Snapchat helps people communicate with their real friends, without some of the public pressure and social comparison features of traditional social media platforms, and intentionally makes it hard for strangers to contact young people.”
The spokesperson continued: “We work closely with many mental health organizations to provide in-app tools and resources for Snapchatters as part of our ongoing work to keep our community safe.”
Meta and lawyers for Rodriguez did not respond to requests for comment.
Karina Newton, Instagram’s head of public policy, wrote in a September blog post that the Journal’s story “focuses on a limited set of findings and casts them in a negative light.”
In other documents retrieved by Facebook whistleblower Frances Haugen, the company found 13.5% of teen girls said Instagram makes thoughts of suicide worse, while 17% of teen girls said Instagram exacerbates eating disorders.
After Haugen gave an interview with “60 Minutes” about the findings, Facebook previously issued this response: “It is not accurate that leaked internal research demonstrates Instagram is ‘toxic’ for teen girls. The research actually demonstrated that many teens we heard from feel that using Instagram helps them when they are struggling with the kinds of hard moments and issues teenagers have always faced. This research, like external research on these issues, found teens report having both positive and negative experiences with social media.”
Diabetes mellitus refers to a group of diseases that affect how your body uses blood sugar (glucose). Glucose is vital to your health because it’s an important source of energy for the cells that make up your muscles and tissues. It’s also your brain’s main source of fuel.
The underlying cause of diabetes varies by type. But, no matter what type of diabetes you have, it can lead to excess sugar in your blood. Too much sugar in your blood can lead to serious health problems.
Chronic diabetes conditions include type 1 diabetes and type 2 diabetes. Potentially reversible diabetes conditions include prediabetes and gestational diabetes. Prediabetes occurs when your blood sugar levels are higher than normal, but not high enough to be classified as diabetes. And prediabetes is often the precursor of diabetes unless appropriate measures are taken to prevent progression. Gestational diabetes occurs during pregnancy but may resolve after the baby is delivered.
Diabetes symptoms vary depending on how much your blood sugar is elevated. Some people, especially those with prediabetes or type 2 diabetes, may sometimes not experience symptoms. In type 1 diabetes, symptoms tend to come on quickly and be more severe.
Some of the signs and symptoms of type 1 diabetes and type 2 diabetes are:
Unexplained weight loss
Presence of ketones in the urine (ketones are a byproduct of the breakdown of muscle and fat that happens when there’s not enough available insulin)
Frequent infections, such as gums or skin infections and vaginal infections
Type 1 diabetes can develop at any age, though it often appears during childhood or adolescence. Type 2 diabetes, the more common type, can develop at any age, though it’s more common in people older than 40.
When to see a doctor
If you suspect you or your child may have diabetes. If you notice any possible diabetes symptoms, contact your doctor. The earlier the condition is diagnosed, the sooner treatment can begin.
If you’ve already been diagnosed with diabetes. After you receive your diagnosis, you’ll need close medical follow-up until your blood sugar levels stabilize.
To understand diabetes, first you must understand how glucose is normally processed in the body.
How insulin works
Insulin is a hormone that comes from a gland situated behind and below the stomach (pancreas).
The pancreas secretes insulin into the bloodstream.
The insulin circulates, enabling sugar to enter your cells.
Insulin lowers the amount of sugar in your bloodstream.
As your blood sugar level drops, so does the secretion of insulin from your pancreas.
The role of glucose
Glucose — a sugar — is a source of energy for the cells that make up muscles and other tissues.
Glucose comes from two major sources: food and your liver.
Sugar is absorbed into the bloodstream, where it enters cells with the help of insulin.
Your liver stores and makes glucose.
When your glucose levels are low, such as when you haven’t eaten in a while, the liver breaks down stored glycogen into glucose to keep your glucose level within a normal range.
Causes of type 1 diabetes
The exact cause of type 1 diabetes is unknown. What is known is that your immune system — which normally fights harmful bacteria or viruses — attacks and destroys your insulin-producing cells in the pancreas. This leaves you with little or no insulin. Instead of being transported into your cells, sugar builds up in your bloodstream.
Type 1 is thought to be caused by a combination of genetic susceptibility and environmental factors, though exactly what those factors are is still unclear. Weight is not believed to be a factor in type 1 diabetes.
Causes of prediabetes and type 2 diabetes
In prediabetes — which can lead to type 2 diabetes — and in type 2 diabetes, your cells become resistant to the action of insulin, and your pancreas is unable to make enough insulin to overcome this resistance. Instead of moving into your cells where it’s needed for energy, sugar builds up in your bloodstream.
Exactly why this happens is uncertain, although it’s believed that genetic and environmental factors play a role in the development of type 2 diabetes too. Being overweight is strongly linked to the development of type 2 diabetes, but not everyone with type 2 is overweight.
Causes of gestational diabetes
During pregnancy, the placenta produces hormones to sustain your pregnancy. These hormones make your cells more resistant to insulin.
Normally, your pancreas responds by producing enough extra insulin to overcome this resistance. But sometimes your pancreas can’t keep up. When this happens, too little glucose gets into your cells and too much stays in your blood, resulting in gestational diabetes.
Risk factors for diabetes depend on the type of diabetes.
Risk factors for type 1 diabetes
Although the exact cause of type 1 diabetes is unknown, factors that may signal an increased risk include:
Family history. Your risk increases if a parent or sibling has type 1 diabetes.
Environmental factors. Circumstances such as exposure to a viral illness likely play some role in type 1 diabetes.
The presence of damaging immune system cells (autoantibodies). Sometimes family members of people with type 1 diabetes are tested for the presence of diabetes autoantibodies. If you have these autoantibodies, you have an increased risk of developing type 1 diabetes. But not everyone who has these autoantibodies develops diabetes.
Geography. Certain countries, such as Finland and Sweden, have higher rates of type 1 diabetes.
Risk factors for prediabetes and type 2 diabetes
Researchers don’t fully understand why some people develop prediabetes and type 2 diabetes and others don’t. It’s clear that certain factors increase the risk, however, including:
Weight. The more fatty tissue you have, the more resistant your cells become to insulin.
Inactivity. The less active you are, the greater your risk. Physical activity helps you control your weight, uses up glucose as energy and makes your cells more sensitive to insulin.
Family history. Your risk increases if a parent or sibling has type 2 diabetes.
Race or ethnicity. Although it’s unclear why, certain people — including Black, Hispanic, American Indian and Asian American people — are at higher risk.
Age. Your risk increases as you get older. This may be because you tend to exercise less, lose muscle mass and gain weight as you age. But type 2 diabetes is also increasing among children, adolescents and younger adults.
Gestational diabetes. If you developed gestational diabetes when you were pregnant, your risk of developing prediabetes and type 2 diabetes increases. If you gave birth to a baby weighing more than 9 pounds (4 kilograms), you’re also at risk of type 2 diabetes.
Polycystic ovary syndrome. For women, having polycystic ovary syndrome — a common condition characterized by irregular menstrual periods, excess hair growth and obesity — increases the risk of diabetes.
High blood pressure. Having blood pressure over 140/90 millimeters of mercury (mm Hg) is linked to an increased risk of type 2 diabetes.
Abnormal cholesterol and triglyceride levels. If you have low levels of high-density lipoprotein (HDL), or “good,” cholesterol, your risk of type 2 diabetes is higher. Triglycerides are another type of fat carried in the blood. People with high levels of triglycerides have an increased risk of type 2 diabetes. Your doctor can let you know what your cholesterol and triglyceride levels are.
Risk factors for gestational diabetes
Pregnant women can develop gestational diabetes. Some women are at greater risk than are others. Risk factors for gestational diabetes include:
Age. Women older than age 25 are at increased risk.
Family or personal history. Your risk increases if you have prediabetes — a precursor to type 2 diabetes — or if a close family member, such as a parent or sibling, has type 2 diabetes. You’re also at greater risk if you had gestational diabetes during a previous pregnancy, if you delivered a very large baby or if you had an unexplained stillbirth.
Weight. Being overweight before pregnancy increases your risk.
Race or ethnicity. For reasons that aren’t clear, women who are Black, Hispanic, American Indian or Asian American are more likely to develop gestational diabetes.
Long-term complications of diabetes develop gradually. The longer you have diabetes — and the less controlled your blood sugar — the higher the risk of complications. Eventually, diabetes complications may be disabling or even life-threatening. Possible complications include:
Cardiovascular disease. Diabetes dramatically increases the risk of various cardiovascular problems, including coronary artery disease with chest pain (angina), heart attack, stroke and narrowing of arteries (atherosclerosis). If you have diabetes, you’re more likely to have heart disease or stroke.
Nerve damage (neuropathy). Excess sugar can injure the walls of the tiny blood vessels (capillaries) that nourish your nerves, especially in your legs. This can cause tingling, numbness, burning or pain that usually begins at the tips of the toes or fingers and gradually spreads upward.
Left untreated, you could lose all sense of feeling in the affected limbs. Damage to the nerves related to digestion can cause problems with nausea, vomiting, diarrhea or constipation. For men, it may lead to erectile dysfunction.
Kidney damage (nephropathy). The kidneys contain millions of tiny blood vessel clusters (glomeruli) that filter waste from your blood. Diabetes can damage this delicate filtering system. Severe damage can lead to kidney failure or irreversible end-stage kidney disease, which may require dialysis or a kidney transplant.
Eye damage (retinopathy). Diabetes can damage the blood vessels of the retina (diabetic retinopathy), potentially leading to blindness. Diabetes also increases the risk of other serious vision conditions, such as cataracts and glaucoma.
Foot damage. Nerve damage in the feet or poor blood flow to the feet increases the risk of various foot complications. Left untreated, cuts and blisters can develop serious infections, which often heal poorly. These infections may ultimately require toe, foot or leg amputation.
Skin conditions. Diabetes may leave you more susceptible to skin problems, including bacterial and fungal infections.
Hearing impairment. Hearing problems are more common in people with diabetes.
Alzheimer’s disease. Type 2 diabetes may increase the risk of dementia, such as Alzheimer’s disease. The poorer your blood sugar control, the greater the risk appears to be. Although there are theories as to how these disorders might be connected, none has yet been proved.
Depression. Depression symptoms are common in people with type 1 and type 2 diabetes. Depression can affect diabetes management.
Complications of gestational diabetes
Most women who have gestational diabetes deliver healthy babies. However, untreated or uncontrolled blood sugar levels can cause problems for you and your baby.
Complications in your baby can occur as a result of gestational diabetes, including:
Excess growth. Extra glucose can cross the placenta, which triggers your baby’s pancreas to make extra insulin. This can cause your baby to grow too large (macrosomia). Very large babies are more likely to require a C-section birth.
Low blood sugar. Sometimes babies of mothers with gestational diabetes develop low blood sugar (hypoglycemia) shortly after birth because their own insulin production is high. Prompt feedings and sometimes an intravenous glucose solution can return the baby’s blood sugar level to normal.
Type 2 diabetes later in life. Babies of mothers who have gestational diabetes have a higher risk of developing obesity and type 2 diabetes later in life.
Death. Untreated gestational diabetes can result in a baby’s death either before or shortly after birth.
Complications in the mother also can occur as a result of gestational diabetes, including:
Preeclampsia. This condition is characterized by high blood pressure, excess protein in the urine, and swelling in the legs and feet. Preeclampsia can lead to serious or even life-threatening complications for both mother and baby.
Subsequent gestational diabetes. Once you’ve had gestational diabetes in one pregnancy, you’re more likely to have it again with the next pregnancy. You’re also more likely to develop diabetes — typically type 2 diabetes — as you get older.
Complications of prediabetes
Prediabetes may develop into type 2 diabetes.
Type 1 diabetes can’t be prevented. However, the same healthy lifestyle choices that help treat prediabetes, type 2 diabetes and gestational diabetes can also help prevent them:
Eat healthy foods. Choose foods lower in fat and calories and higher in fiber. Focus on fruits, vegetables and whole grains. Strive for variety to prevent boredom.
Get more physical activity. Aim for about 30 minutes of moderate aerobic activity on most days of the week, or at least 150 minutes of moderate aerobic activity a week.
Lose excess pounds. If you’re overweight, losing even 7% of your body weight — for example, 14 pounds (6.4 kilograms) if you weigh 200 pounds (90.7 kilograms) — can reduce the risk of diabetes.
Don’t try to lose weight during pregnancy, however. Talk to your doctor about how much weight is healthy for you to gain during pregnancy.
To keep your weight in a healthy range, focus on permanent changes to your eating and exercise habits. Motivate yourself by remembering the benefits of losing weight, such as a healthier heart, more energy and improved self-esteem.
Sometimes medication is an option as well. Oral diabetes drugs such as metformin (Glumetza, Fortamet, others) may reduce the risk of type 2 diabetes — but healthy lifestyle choices remain essential. Have your blood sugar checked at least once a year to check that you haven’t developed type 2 diabetes.
If the initial data is correct, the Omicron-Variant of Covid is proving to be of Highly Contagious – Low Virulence.
The Omicron variant is less likely to lead to less severe disease in people who have taken vaccines or had Covid-19 in the past, two studies from the UK have said.
Taken together with findings from South Africa – all three studies were released on Wednesday – there is now sound scientific basis to conclude the variant is less virulent than others, especially Delta, which caused a devastating outbreak in India last summer and sparked new waves in other countries.
The findings are the first encouraging scientific evidence linked to the variant of concern (VOC) discovered last month when it started tearing through parts of South Africa at a rate not seen with any other Sars-Cov-2 variant. Scientists soon discovered it was also the most resistant configuration of the coronavirus, leading to higher odds of repeat and vaccine breakthrough infections.
If the Omicron variant was to be as virulent, or more, than Delta, the implications would have been dire, although its high transmissibility and resistance still pose a threat.
“Our analysis shows evidence of a moderate reduction in the risk of hospitalisation associated with the Omicron variant compared with the Delta variant. However, this appears to be offset by the reduced efficacy of vaccines against infection with the Omicron variant. Given the high transmissibility of the Omicron virus, there remains the potential for health services to face increasing demand if Omicron cases continue to grow at the rate that has been seen in recent weeks,” said professor Neil Ferguson of Imperial College London, which released the analysis of Omicron and Delta cases in England.
Two UK studies, similar severity findings
The Imperial College study included all RT-PCR-confirmed Covid-19 cases recorded between December 1-14 in England. It found that Omicron cases have, on average, a 15-20% reduced risk of needing to visit a hospital (the lowest level of severity) and an approximately 40-45% reduced risk of a hospitalisation resulting in a stay of one or more nights.
It also found that a past infection offered approximately a 50-70% reduction in hospitalisation risk compared. All of these comparisons were made against risks of hospitalisation seen with the Delta variant.
The researchers estimate that in unvaccinated people being infected for the first time, the risk of hospitalisation may be lowered by 0-30%, suggesting the severity in completely immune-naive people may not be very different from those who had a Delta infection for the first time, without any vaccine.
The other UK study was from Scotland. Although based on a small number of hospitalisations, the study made similar findings: those with Omicron infections were 68% less likely to need hospitalisation compared to people infected with the Delta variant.
Both reports, as well as the South African study, are yet to be peer-reviewed.
The Imperial College researchers also said in their study that Omicron infections in people with vaccination may be even less likely to require ICU admission or lead to death when compared to Delta variant, “given that remaining immune protection against more severe outcomes of infection are expected to be much higher than those against milder endpoints”.
Need for vaccines, boosters
The detailed findings corroborate lab studies that show people with booster doses have a more adequate immune response to counter the Omicron variant. In their real-world analysis, the Scotland report found a 57% reduction in the risk of symptomatic infection in people who were infected with the VOC compared to those who just had two doses at least 25 weeks prior.
The detailed Imperial College findings made similar findings. For instance, people with two doses of the AstraZeneca vaccine (used in India as the Covishield vaccine), had a higher risk ratio of 0.37 than those with three doses of the same vaccine (0.21). These risk ratios mean two doses reduced the risk of hospitalisation by 63% while three doses cut it by 79%.
Crucially, the report added, people who took the AstraZeneca vaccine had a lower risk in needing to visit a hospital if infected by the Omicron variant when compared to the equivalent risk in the case of a Delta variant infection. In the case of Pfizer-BioNTech or Moderna vaccines, the likelihood of requiring a hospital visit – defined as the lowest level of severity – were similar between Omicron and Delta infections.
The report also stressed on the need to vaccinate the unvaccinated, especially those who did not have a past infection. “The proportion of unvaccinated individuals infected is likely to be substantially higher. In that context, our finding that a previous infection reduces the risk of any hospitalisation by approximately 50% and the risk of a hospital stay of 1+ days by 61% (before adjustments for under ascertainment of reinfections) is significant,” the report said.
With reports of new cases surfacing, the overall number of Omicron cases in India has now reached 33. According to experts, the spread of the new variant is less concerning than that of Delta as the symptoms are mild. While this is partly because of the nature of this new variant, another reason might be the high rate of seropositivity of Indians, experts have said.
“India has the advantage of a very high rate of ‘seropositivity’ of 70, 80 per cent, and in big cities more than 90 per cent people already have antibodies,” Rakesh Mishra, former Director of CSIR-Centre for Cellular and Molecular Biology (CCMB) here, told PTI. Even if people get infected by Omicron, it will be very mild and mostly asymptomatic, Mishra said.
A fresh wave of the pandemic may come even without Omicron, Mishra said referring to the fresh waves in Europe. Ruling out the possibility of a surge in hospitalisation, he said wearing the mask, maintaining social distancing and getting vaccinated remain the three major weapons against future waves.
All Omicron cases in India are mild and there has been no report of Omicron death in India and in any country of the world. The common symptoms are weakness, sore throat etc. Many Omicron patients of India have already recovered and tested negative for Covid.
Capital Delhi reported a new Omicron case on Saturday as a Zimbabwe-returnee tested positive. Reports said the patient only complained of weakness.
Evidence about the safety and effectiveness of COVID-19 vaccination during pregnancy, although limited, has been growing. These data suggest that the benefits of receiving a COVID-19 vaccine outweigh any known or potential risks of vaccination during pregnancy.
No adverse pregnancy-related outcomes occurred in previous clinical trials that used the same vaccine platform as the J&J/Janssen COVID-19 vaccine: Vaccines that use the same viral vector have been given to pregnant people in all trimesters of pregnancy, including in a large-scale Ebola vaccination trial. No adverse pregnancy-related outcomes, including adverse outcomes affecting the baby, were associated with vaccination in these trials. Learn more about how viral vector vaccines work.
COVID-19 vaccines do not cause infection, including in pregnant people or their babies: None of the COVID-19 vaccines contain the live virus that causes COVID-19 so a COVID-19 vaccine cannot make anyone sick with COVID-19, including pregnant people or their babies.
Early data on the safety of receiving an mRNA COVID-19 vaccine (Moderna or Pfizer-BioNTech) during pregnancy are reassuring:
CDC released the first U.S. data on the safety of receiving an mRNA COVID-19 vaccine during pregnancy. The report analyzed data from three safety monitoring systems in place to gather information about COVID-19 vaccination during pregnancy. These early data did not find any safety concerns for pregnant people who were vaccinated or their babies.1
Another report looked at pregnant people enrolled in the v-safe pregnancy registry who were vaccinated before 20 weeks of pregnancy. Scientists did not find an increased risk for miscarriage among people who received an mRNA COVID-19 vaccine during pregnancy.2
Many pregnancies reported in these safety monitoring systems are ongoing. CDC will continue to follow people vaccinated during all trimesters of pregnancy to better understand effects on pregnancy and babies.
Early data suggest receiving an mRNA COVID-19 vaccine during pregnancy reduces the risk for infection: A recent study from Israel compared pregnant people who received an mRNA COVID-19 vaccine with those who did not. Scientists found that vaccination lowered the risk of infection from the virus that causes COVID-19.3
Vaccination of pregnant people builds antibodies that might protect their baby: When pregnant people receive an mRNA COVID-19 vaccine during pregnancy, their bodies build antibodies against COVID-19, similar to non-pregnant people. Antibodies made after a pregnant person received an mRNA COVID-19 vaccine were found in umbilical cord blood. This means COVID-19 vaccination during pregnancy might help protect babies against COVID-19. More data are needed to determine how these antibodies, similar to those produced with other vaccines, may provide protection to the baby.4
Additional clinical trials that study the safety of COVID-19 vaccines and how well they work in pregnant people are underway or planned. Vaccine manufacturers are also collecting and reviewing data from people in the completed clinical trials who received a vaccine and became pregnant.
Vaccine Side Effects
Side effects can occur after receiving any of the available COVID-19 vaccines, especially after the second dose for vaccines that require two doses. Pregnant people have not reported different side effects from non-pregnant people after vaccination with mRNA COVID-19 vaccines (Moderna and Pfizer-BioNTech vaccines). If you experience fever following vaccination you should take acetaminophen (Tylenol®) because fever—for any reason—has been associated with adverse pregnancy outcomes. Learn more at What to Expect after Getting a COVID-19 Vaccine.
Although rare, some people have had allergic reactions after receiving a COVID-19 vaccine. Talk with your healthcare provider if you have a history of allergic reaction to any other vaccine or injectable therapy (intramuscular, intravenous, or subcutaneous).
Key considerations you can discuss with your healthcare provider include:
The unknown risks of developing a severe allergic reaction
The benefits of vaccination
If you have an allergic reaction after receiving a COVID-19 vaccine during pregnancy, you can receive treatment for it.
Neanderthal-inherited genetic material is found in all non-African populations and was initially reported to comprise 1 to 4 percent of the genome. This fraction was later refined to 1.5 to 2.1 percent. It is estimated that 20 percent of Neanderthal DNA currently survives in modern humans.
Relation to severity of Covid
Response to Covid infection varies from person to person. Some have severe covid infection, need ventilator and some remain unaffected. There is interest in the individual factors which influence the outcome of Covid infection. One such factor is the genetic predisposition.
Covid-19 patients with a snippet of Neanderthal DNA that crossed into the human genome some 60,000 years ago run a higher risk of severe complications from the disease, researchers have reported.
People infected with the new coronavirus, for example, who carry the genetic coding bequeathed by our early human cousins are three times more likely to need mechanical ventilation, according to a study published Wednesday in Nature.
There are many reasons why some people with Covid-19 wind up in intensive care and others have only light symptoms, or none at all.
Advanced age, being a man, and pre-existing medical problems can all increase the odds of a serious outcome.
But genetic factors can also play a role, as the new findings makes clear.
“It is striking that the genetic heritage from Neanderthals has such tragic consequences during the current pandemic,” said co-author Svante Paabo, director of the department of genetics at the Max Planck Institute for Evolutionary Anthropology.
Recent research by the Covid-19 Host Genetics Initiative revealed that a genetic variant in a particular region of chromosome 3 — one of 23 chromosomes in the human genome — is associated with more severe forms of the disease.
That same region was known to harbour genetic code of Neanderthal origins, so Paabo and co-author Hugo Zeberg, also from Max Planck, decided to look for a link with Covid-19.
They found that a Neanderthal individual from southern Europe carried an almost identical genetic segment, which spans some 50,000 so-called base pairs, the primary building blocks of DNA.
Tellingly, two Neanderthals found in southern Siberia, along with a specimen from another early human species that also wandered Eurasia, the Denisovans, did not carry the telltale snippet.
Modern humans and Neanderthals could have inherited the gene fragment from a common ancestor some half-million years ago, but it is far more likely to have entered the homo sapiens gene pool through more recent interbreeding, the researchers concluded.
The potentially dangerous string of Neanderthal DNA is not evenly distributed today across the globe, the study showed.
Some 16 percent of Europeans carry it, and about half the population across South Asia, with the highest proportion — 63 percent — found in Bangladesh.
This could help explain why individuals of Bangladeshi descent living in Britain are twice as likely to die from Covid-19 as the general population, the authors speculate.
In East Asia and Africa the gene variant is virtually absent.
About two percent of DNA in non-Africans across the globe originate with Neanderthals, earlier studies have shown.
Denisovan remnants are also widespread but more sporadic, comprising less than one percent of the DNA among Asians and Native Americans, and about five percent of aboriginal Australians and the people of Papua New Guinea.
