वैज्ञानिकों ने पता लगाया है कि हल्के लक्ष्णों वाले कोविड का काफी अवधि तक असर रहता है और लोगों के ठीक होने पर भी इसका प्रभाव पड़ता है। अमेरिका के लॉस एंजिल्स के शोधकर्ताओं ने पता लगाया है कि जिन लोगों में हल्के लक्ष्णों वाला कोरोना था उनमें ऐसे एंटीबाडी पाए गए हैं जो शरीर को खुद ही नष्ट करने लगते हैं और ऐसे मरीजों की रिकवरी में भी अधिक समय लगता है और ये एंटीबाडी उनकी कोशिकाओं को ही नष्ट करने लगते हैं।
सेडार सिनाई मेडिकल सेंटर के शोधकर्ताओं के हवाले से येरूशलम पोस्ट ने बताया कि इन मरीजों के शरीर में खुद को नष्ट करने वाले एंटीबा़डीज बनने से इन्हें ठीक होने में देरी होती है। इस दल ने 177 मरीजों पर शोध किया था।
यह शोध जर्नल ऑफ ट्रांसलेशनल मेडिसिन में छपा है और इसमें कहा गया है कि जिन लोगों को पहले कोविड संक्रमण हुआ था उनके शरीर में जो एंटीबाडीज बने थे उन्होंने बाद में अपनी ही कोशिकाओं को ही निशाना बनाना शुरू कर दिया था और इसी वजह से उन्हें ठीक होने में इतना समय लगा था।
उन्होंने अपने आसपास की कोशिकाओं को नष्ट कर दिया था और इसकी वजह ये इन मरीजों को कोरोना से उबरने में इतना समय लगा ।

While wearing double masks, which helps create a strong barrier against Covid-19 infection spread via airborne viral particles, has become the new normal, prolonged wearing of masks can develop hydration issues or other nagging breathing troubles, health experts said on Wednesday.
There has been enough evidence through the pandemic to show the importance of masks for effective pandemic control. At the start of the pandemic, it was seen that countries (primarily Asian nations) which enforced early masking had lesser mortality rates as compared to countries in the West where compulsory mask wearing was introduced quite late.
"Prolonged mask wearing can be associated with certain problems the most common being headaches, dehydration, acne and difficulty in breathing," Radhika Banka, Consultant Pulmonologist at P.D. Hinduja Hospital & MRC, Mumbai, told IANS.
Breathing issues are "usually seen in mouth breathers and in people with underlying respiratory problems such as COPD (Chronic Obstructive Pulmonary Disease)", she added.
According to Ravi Shekhar Jha, Additional Director and HOD, Pulmonology, at Fortis Escorts Hospital, Faridabad, wearing double mask for long hours can also lead to dryness.
"It is because natural humidification of nasal mucosa gets impaired," Jha said.
There are various masks available in the market, including cloth masks, surgical masks and respirators such as N-95s.
The cloth mask has the least protection and the US Centre of Disease Control and Prevention (CDC) recommends wearing a disposable surgical mask along with a cloth mask for additional protection. For surgical masks, the knotted technique (that is knotting the ear loops to provide better fit and prevent leakage from the sides) is recommended.
But with full vaccination rolled out in most countries, are double masks still required?
"Even after double dose vaccination, people can get breakthrough infections and can still be asymptomatic carriers and spread the infection. Hence masking is important even after double vaccination," Banka said.
The health experts stated that for people living in India, double masks become more important as vaccination of children has not yet begun in the country, and asymptomatic transmission is the highest from children. Added to this is a high population density, where social distancing is not practically possible in many cases.
Most of the countries which have made masks voluntary are those in the West with low population density, where social distancing is feasible. These countries have managed to vaccinate more than 80 per cent of their population with two doses. Also, masks in these countries are still recommended in enclosed spaces, public transports, healthcare facilities etc.
"With only 48 per cent of our population being vaccinated with one dose and 25 per cent being vaccinated with two doses, I do not think India can yet take the risk of removing the mandatory use of masks," Banka said.
However, according to Jha, "A single mask, if worn properly, is sufficient."
"People who wear double masks, have this tendency of adjusting their masks repeatedly due to breathing issues, and that way the whole purpose of wearing a mask is defeated," he said.
Jha added that for someone like a healthcare worker, who is in an area with high concentration of Covid viral droplets, an N-95 mask should be worn all the time. For other situations, a normal surgical mask (single) is sufficient.
"We need to ensure that masks are worn properly, with proper seal at nose. Improperly worn masks are more dangerous. It is also important to keep in mind that a mask alone may not protect. One needs to follow hand hygiene as well as maintain social distancing," Jha advised.
Although several countries have loosened mask restrictions citing vaccine efficacy, various studies and health experts have stressed on the need for continuing wearing masks, even after being fully vaccinated, including booster shots; and following other protective measures such as physical distancing and handwashing.
A recent study led by researchers from the Monash University and the University of Edinburgh analysed more than 30 studies from around the world and found a statistically significant 53 per cent reduction in the incidence of Covid with mask wearing, and 25 per cent reduction with physical distancing. Handwashing also indicated a substantial 53 per cent reduction in Covid incidence.
Most people are able to wear masks fairly well for a few hours, but if your job requires you to wear masks for a prolonged period, it is essential to take adequate breaks to hydrate oneself and prevent any skin problems, Banka suggested. (Agency)

<br>People suffering from cardiovascular diseases have had it worse during the ongoing pandemic. Heart patients have been living in the constant fear of sudden deaths and severe infections. Over the past one year, we have witnessed a spike in the number of deaths due to cardiac arrest, post Covid infections. During the second wave, one of the most common aftereffects was sudden deaths due to cardiac arrest post Covid. Therefore, it was advised that people with a history of heart diseases should get themselves vaccinated. Although people believe in myths and misconceptions around Covid-19 vaccines, it is important, especially for heart patients to take the vaccine shot. Hence, it is now imperative to address the following question: are Covid-19 vaccine safe for people with heart conditions?
Some safety concerns or adverse reactions of Covid-19 vaccinations that have arose are guillan-barre syndrome, increased blood clots, myocarditis (inflammation of the heart muscle), or anaphylaxis (acute allergic reaction to an antigen). However, what has been documented is that most of the mentioned side-effects tend to show up weeks following vaccination, and not long after it. It has been further witnessed that the <br>side-effects, which have consequential risks appear, most commonly after a month of inoculation. Hence, they can be managed well if diagnosed in time. There are no <br>side-effects that are severely detrimental to our health and well-being.
Moreover, the severe side-effects associated with vaccines are fewer than reported averages across the general population. For example, the risk of developing gullian-barre syndrome is said to be 17 times more likely with general infections in comparison to vaccines.
Additionally, reports suggest that Covid-19 vaccines are not only safe for people with heart diseases, but they are also very important. We are at a point where there is a growing risk of emerging variants, there heart patient being one of the most vulnerable populations in the society need to get their vaccine shots as soon as possible.
If one is still concerned about the safety, they must note that the vaccines are safe for all age groups. Earlier this year, the American Heart Association released a statement urging everyone fitting the eligibility criteria to get their vaccination shots. The statement had particularly mentioned people with cardiovascular risk factors, heart diseases, and heart attack and stroke survivors to get vaccinated as soon as possible since they are at a greater risk from the virus than the vaccine.
However, some common effects to note post vaccination are fever, fatigue, headache, and joint pain. Additionally, pain in the injection site may also be witnessed. Whether a person is healthy or is someone with a pre-existing heart ailment, these side-effects from the vaccine will be the same in everyone. As a heart patient, the symptoms will not differ from others. It is, however, always recommended to consult your doctor and also keep a constant check post vaccination.
It is most important to note that whether a person is healthy or is someone with a heart ailment, getting vaccinated does not mean that one is safe from contracting the virus. Vaccination reduces the chances for hospitalization; however, cases of breakthrough infections have increased in current times with the emergence of new variants. Therefore, physical distancing, wearing a mask, maintaining hand hygiene, and staying at home is extremely important.

London, Aug 17 (IANS) Patients with Long Covid syndrome continue to have higher measures of blood clotting, which may help explain their persistent symptoms, such as reduced physical fitness and fatigue, finds a research.
While the dangerous clotting has been observed in patients with severe acute Covid-19, far less is known about Long Covid syndrome, where symptoms can last weeks to months after the initial infection has resolved and is estimated to affect millions of people worldwide.
Researchers from RCSI University of Medicine and Health Sciences in Ireland, examined 50 patients with symptoms of Long Covid syndrome to better understand if abnormal blood clotting is involved.
They discovered that clotting markers were significantly elevated in the blood of patients with Long Covid syndrome compared with healthy controls. These clotting markers were higher in patients who required hospitalisation with their initial Covid-19 infection, but they also found that even those who were able to manage their illness at home still had persistently high clotting markers.
In the study, published in the Journal of Thrombosis and Haemostasis, the team observed that higher clotting was directly related to other symptoms of Long Covid syndrome, such as reduced physical fitness and fatigue. Even though markers of inflammation had all returned to normal levels, this increased clotting potential was still present in the Long Covid patients.
"Because clotting markers were elevated while inflammation markers had returned to normal, our results suggest that the clotting system may be involved in the root cause of Long Covid syndrome," said lead author Dr Helen Fogarty, doctoral student at the Irish Centre for Vascular Biology in the RCSI School of Pharmacy and Biomolecular Sciences.
In a separate study, a team from the University of Cambridge, in the UK, found that small protein molecules called cytokines could have a link to the Long Covid condition, the Daily Mail reported.
Cytokines, which are produced by the body in response to infections, are often found to be lingering in a person's body for months after infection.
They developed a simple new blood test that may determine whether or not Covid-19 survivors will experience long-term symptoms.

Did you know silk pillowcases keep your hair hydrated? It also helps with brittle hair. People traditionally use cotton pillow cases as they are unaware of the fact that cotton is more permeable and hence absorbs all the moisture from your hair. But silk is known to do the exact opposite. It keeps the moisture right where it belongs. Hence, sleeping on a silk bed sheet and a silk pillowcase at night is highly recommended.
Old School Massage
If you are looking for a full proof way to grow your hair in a healthy manner, a scalp massage before bed is the way to go. Scalp massages are known to increase hair thickness by stretching the cells of your hair follicles. This encourages the follicles to produce thicker hair in return. It also helps dilate blood vessels beneath the skin thereby encouraging hair growth.
Vitamins are Your Best Friend
Healthy diet helps in keeping the locks luscious, a mix of vitamins and healthy fats is helpful. Like any other body part, our hair also needs the correct amount of nutrients in order to stay healthy. While factors such as age, genetics and hormones also affect hair growth, optimal nutrient intake is key. Vitamin A, C, D, E and B -- vitamins help our hair the most. Therefore 'eating right' all day, and eating food which contains vitamins is a good idea.

When a woman hears the news she has conceived and will be mother soon, many thoughts cross her mind about pregnancy, birthing and finally her journey to parenthood.
Most moms-to-be in nuclear families don't have any experience of handling a baby post birth. This makes them nervous about the whole process and apprehensive about whether or not she will be able to breastfeed the baby. As a lactation consultant, I often come across mothers who have many questions related to breastfeeding and milk production such as when will the milk production start, what does lactation delay look like, will I produce enough colostrum?
It is important to understand that hormones play a major role in pregnancy and milk production. During pregnancy, hormonal activities increase, and this in turn causes the mammary glands to produce milk. However, this is all just preparation for breastfeeding. Mature milk production can start within three to five days of the baby being born.
Milk production starts during the midpoint of pregnancy that is around 16-22 week of pregnancy. During the second trimester, your breasts begin to create colostrum. Colostrum is the first food your breasts produce for your baby. It is usually thick and yellowish and contains high amounts of proteins and antibodies to strengthen your baby's immune system. Many mothers are not aware about this because it does not flow like mature milk. It might start as few watery drops as this is first milk that's called "colostrum".
Colostrum does not leak and not all pregnant mothers produce it during pregnancy, for many colostrum starts after the birthing process. This is absolutely normal. During the pregnancy a mother-to-be should not express or pump colostrum as it might trigger the labor process. Mothers can use a breast pad just for comfort. If there is good quantity of colostrum or leaky colostrum, one can express it with hand after 37 weeks of pregnancy and store it.

You may start producing breast milk months or weeks before your due date of delivery. One of the first signs that your breasts have started producing milk is that they will become fuller and heavier, and they may even hurt sometimes. Immediately after the birth, a mother will see a transparent or yellowish colour of drops at the nipple area i.e. colostrum or liquid gold.
It is the first stage of milk production. It is thick, sticky, concentrated and very nutritious. The baby should suckle at the breast with in one hour of birth, this period is called Golden hour. Colostrum is known as "liquid gold" because it's packed with protein, growth factors, white blood cells, and antibodies, especially Immunoglobulin A (IgA) to fight off infections. It's very important for the baby's health and immune system. In the first 24 hours after your baby is born, a mother will produceï¿½on an average - 1 ounce (30 milliliters) within 24 hours. On the second and third day, she will make approximately 2 ounces (60 milliliters) of colostrum. Some people's breasts may leak during this colostrum phase. This is normal. Within three to five days of delivery, your breasts go through a transition where mature milk gradually replaces colostrum. By the time your baby is around two weeks old, your breasts will only be producing mature breast milk.
Colostrum is replaced by transitional milk which will start from day 3-5 up to 2 weeks. Watery or yellowish milk will change in to whitish milk. The breast will feel warm and full. Transitional milk will be combination of colostrum and mature milk. Frequent breastfeeding or regular milk expression will help with milk production and also o avoid engorgement. Transitional milk will be replaced by mature milk usually between 10 to 15 days. It's a whitish milk packed with nutrients and its production depends upon the demand and supply principle. Frequent nursing will stimulus mothers brain to release milk hormone and accordingly milk supply will be there.
Once supply of breastmilk settles down it keeps on adjusting as per demand of the baby, for example if the baby gets growth spurts baby it will demand frequent feeding and this might cause confusion in the mother that her supply is not enough and the baby is hungry; but actually the baby is expressing its demand to the mother's body so that the milk supply increases and settles down mostly within a week.
As per my clinical experience many new mothers complain of low milk supply and after assessment most of the cases the demand or stimulus to mothers body is missing. This can be because of many reasons like preterm baby, medical condition of the mother and baby, supplementation of formula, stress or postpartum depression etc. For example if a mother is giving formula feed to the baby without trying to breastfeed, that demand or stimulus to the mother's body will be missing and accordingly her body will produce less breastmilk.
If baby is preterm and cheeks stability is not there, there might be ineffective or nonnutritive suckling by the baby on the breast which further reduces the milk supply. Because of some external stress factors or postpartum depression milk hormones can be affected and a mother might face low milk production.
Breastfeeding takes a lot of diligent commitment, effort, and energy. Consult a lactation specialist or who will help you answer your questions and continually educate you about the ways your body is changing as milk production increases. Early initiation at the breast is good start for good milk production. If you are not comfortable medically to feed your baby after birth, colostrum expression should be done within one hour of the birth followed by frequent feeding or removal of milk.
An expecting couple should prepare themselves during pregnancy for breastfeeding. Antenatal classes are great help which help in proper guidance and support that will help them sail through this journey of breastfeeding.
