Air pollutant may increases asthma attack in urban children

Air pollutant may increases asthma attack in urban children

Comments 0 Comment

Viral respiratory infections are a typical cause of asthma attacks. Thisinvolve a worsening of the inflammation and a narrowing of the bronchial airways. Nevertheless, non-viral causes of asthma attacks are also possible.

Asthma attacks are more likely to occur when people are exposed to more air pollutants. However, the molecular mechanisms by which air pollutants might cause asthma attacks are poorly understood.

A recent study found that children living in metropolitan areas were more likely to experience asthma attacks. Due to exposure to greater levels of air pollutants, specifically ozone and fine particle matter. The most frequent cause of asthma attacks is viral respiratory infections. However nonviral variables including air pollution can also contribute to an asthma attack’s onset.

According to a recent study, children who live in urban areas are more likely to experience asthma episodes. Also, their lung function declines when air pollution levels are higher. Particularly when ozone and fine particulate matter concentrations are high.

Researchers found that these air pollutants could cause asthma attacks. Even when their concentrations were below the threshold set by the federal government for air quality.

The researchers also found that elevated ozone and fine particulate matter were linked to particular inflammatory pathways in the airways. Providing further insight into how elevated levels of pollutants may raise the likelihood of asthma episodes in urban children.

Asthma attacks: What to know

The primary airways in the lungs, the bronchi, and their branching, become inflamed and constricted in people with asthma. Chest constriction, shortness of breath, coughing, and wheezing are among asthmatic symptoms. They tend to get worse while the condition is exacerbating.

The lung airways are further constricted during an asthma exacerbation. Sometimes referred to as an asthma attack, as a result of the airway cells’ inflammation and the bronchial muscles’ spasm. Moreover, there is an increase in mucus production at the same time, which obstructs the airways.

One of the most frequent reasons for asthma flare-ups in both children and adults is respiratory tract viral infections. However, non-viral factors including allergens, pollen, and pet hair, as well as non-viral diseases, can also contribute to an asthma exacerbation.

Also, a number of epidemiological studies have linked the frequency of asthma attacks and air pollution levels. Asthma attacks have been connected to higher concentrations of a number of air pollutants. This including fine particulate matter, ozone, nitrogen dioxide, and sulphur dioxide.

One of the most prevalent chronic diseases in children is asthma. Also, research indicates that children who live in low socioeconomic and urban neighbourhoods have greater asthma prevalence and morbidity rates. These communities typically have higher air pollution levels. This may help to explain why asthma is more common and severe in children living in low-income metropolitan regions.

Yet, particularly in sensitive populations like children with severe asthma, the molecular pathways behind asthma exacerbation during non-viral respiratory infections are poorly known. Also, the variations in the mechanisms behind asthma flare-ups brought on by viral infections and airborne contaminants have not been defined.

Impact of air pollutants on asthma

In the current study, the researchers first looked at the relationship between air pollution levels and asthma flare-ups in kids and teenagers living in metropolitan areas. Data from an earlier observational trial titled “Mechanisms Behind Asthma Exacerbations Prevented and Sustained with Immune-based Treatment Part 1” was analysed by the researchers.

The current study’s objective was to particularly comprehend the molecular basis of non-viral asthma exacerbations brought on by air pollution using the MUPPITS1 data.

208 children with asthma who were prone to exacerbations and lived in low-income areas of nine American cities were enrolled in the MUPPITS1 study. Following the onset of respiratory illness symptoms in these subjects, the study took measurements of lung function and nose swabs.

The nasal samples were utilised by the researchers to identify whether non-viral or viral infections were to blame for the respiratory ailment. They further divided the subjects into groups according to whether or not an asthma exacerbation occurred when they were unwell.

The Environmental Protection Agency (EPA) collected data on specific pollutant concentrations and the Air Quality Index for each study region. The researchers then used this information.

The researchers reported that the Air Quality Index values were higher nine days before and after the beginning of symptoms in participants with a non-viral asthma exacerbation than those with a viral asthma exacerbation. The participants who had non-viral asthma exacerbations also showed a negative correlation between the Air Quality Index values and lung function.

Profile of gene expression

The nasal samples from the MUPPITS1 investigation were then used by the researchers to analyse variations in gene expression.

In both viral and non-viral asthma exacerbations, the Air Quality Index was associated with common gene expression patterns. Pointing to the existence of fundamental processes underlying asthma attacks. Moreover, changes in the gene expression profile that were unique to non-viral asthma exacerbations were linked to Air Quality Index levels.

It was found that fine particulate matter concentrations were directly correlated with an increase in genes. It is linked to excessive mucus secretion and proinflammatory cytokines, a class of signalling proteins, in non-viral asthma exacerbations.

The expression of tissue kallikreins, a class of enzymes involved in inflammation and increased in asthma, was positively linked with fine particulate matter concentrations.

The majority of the respiratory tract is lined by epithelial cells. They shield the respiratory system from allergens, pathogenic agents, and debris that can injure it when inhaled. The expression of genes related to epithelial cell barrier function was also correlated with the amounts of fine particulate matte

According to researchers, the greater asthma prevalence and morbidity in children living in urban centres may be explained. Due to the molecular pathways implicated in asthma exacerbations linked to certain air contaminants.

Identifying the molecular pathways that are unique to asthma flare-ups brought on by increased levels of air pollution may potentially aid in the development of therapies that target these pathways.

Moreover, using air filters during periods of high air pollution and using personal air quality monitoring equipment may help reduce the risk of asthma flare-ups related to air pollution. The study was observational in nature, and the authors noted that it did not prove a connection between air pollution and the frequency of asthma attacks.

Facts

To better prevent and treat asthma in these patients, it is concluded that more research is required to understand the underlying processes of the connection.

Although initiatives like selective planting around school playgrounds could help limit exposure among this vulnerable demographic, air pollution in underdeveloped areas has also been linked to impaired cognitive capacities in youngsters.

Is Upper Respiratory tract, the most common infection?

Is Upper Respiratory tract, the most common infection?

Comments 0 Comment

One of the most prevalent viral disorders, acute upper respiratory infections typically affect the nose and throat. They can persist up to 3 weeks and are frequently untreated.

Millions of people experience upper respiratory infections (URIs) each year. Although bacteria can also cause them, viruses typically cause them. The majority of URI sufferers recover within a few weeks, but some may experience complications that need medical attention.

What is Upper Respiratory Tract Infection?

Nasal passageways and the throat are impacted by an upper respiratory infection (URI). Unless a person also has a persistent respiratory disease like Asthma, the therapy is typically straightforward. When a virus or bacteria enter the body, typically through the mouth or nose, a URI develops. Sneezing, coughing, or touching another person might spread the virus.

Adults often experience two to three URIs annually. Children, particularly young children, may experience more of these infections because of the immature state of their immune systems. Children are less likely than adults to wash their hands after sneezing or wipe their noses when necessary, thus children who spend a lot of time with other children may be more susceptible to these infections.

Homes, businesses, and other enclosed public spaces can pose a significant danger for the spread of URIs. A URI typically lasts 7–10 days, however it can occasionally last up to 3 weeks. These infections can occasionally worsen into more dangerous conditions like sinus infections or pneumonia.

Symptoms of upper Respiratory tract infection

While various URIs can induce a variety of symptoms, the following are some of the more typical ones:

  • coughing
  • nasal congestion that is uncomfortable
  • a little fever
  • extra mucous
  • nasal obstruction
  • pressure or discomfort in the face
  • running nose
  • a painful or itchy throat
  • sneezing

Additional signs can include:

  • poor breath
  • bodily pains
  • a migraine
  • Hyposmia, also known as a loss of scent
  • scratchy eyes

Affected individuals often experience symptoms 1-3 days after coming into touch with an infected person, and they last for 7–10 days.

Types of upper Respiratory tract infection

There are various URI varieties, and medical professionals categorise them based on which area of the respiratory system they mostly impact. URI types include:

The common cold

A cold can be brought on by numerous viruses. Some signs could be:

  • a runny or clogged nose
  • an upset stomach
  • headaches
  • muscular pain
  • sneeze and coughing
  • alterations in flavour and odour
  • the fever
  • stress in the face and ears

After 10 to 14 days of at-home treatment, the symptoms often disappear.

Sinusitis

Inflammation of the sinuses, or sinusitis, can result from an infection in another respiratory system organ. Due to difficulty draining, the inflammation may cause increased mucus production and closed sinuses.

Some signs of sinusitis include:

  • discomfort in the forehead, cheeks, or eye area
  • nasal discomfort and pressure
  • nasal dripping
  • a stuffy nose
  • a diminished ability to smell
  • the fever
  • poor breath

If a person’s symptoms don’t go away after more than 10 days, they should see a doctor.

Laryngitis

This is inflammation of the larynx, which is another name for the vocal chords.

Some typical signs include:

  • a voice loss or hoarseness
  • a persistent cough and throat irritation
  • an upset stomach

Typically, the symptoms last 7 to 10 days.

Pharyngitis

Inflammation of the mucous membranes lining the pharynx, or back of the throat, is known as pharyngitis. It frequently happens with URIs.

Symptoms of pharyngitis include the following:

  • an itchy or painful throat
  • inflammation
  • fever
  • headache
  • having trouble swallowing

The throat’s walls may have ulcers, a doctor may discover.

Additional symptoms

The following situations require medical intervention for the individual:

  • an extreme fever
  • severely distressed breathing
  • having trouble swallowing

Who is at risk for upper respiratory infection infection?

The most frequent reason for healthcare visits in the US is the common cold. Aerosol droplets and direct hand-to-hand contact are two ways that URIs are transferred from one person to another. The risk increases:

  • When a sick person sneezes or coughs without covering their mouth and nose, virus-carrying droplets are released into the atmosphere.
  • when people are crammed together or in an enclosed space, such as at daycare centres, hospitals, and other establishments.
  • if you suffer from an illness like asthma or allergic rhinitis.
  • if you have a compromised immune system, such as cystic fibrosis or HIV in smokers.
  • when people use corticosteroids, such as prednisone.

What are the symptoms and causes of Tuberculosis?

What are the symptoms and causes of Tuberculosis?

Comments 1 comment

A potentially dangerous infectious disease that mostly affects the lungs is tuberculosis (TB). People can contract tuberculosis from one another by coughing or sneezing small droplets of bacteria into the air.

Infections of tuberculosis, once uncommon in wealthy nations, started rising in 1985, in part due to the appearance of HIV, the virus that causes AIDS. HIV impairs the immune system, making it incapable of warding off TB pathogens. In the United States, tuberculosis started to decline once more in 1993 as a result of more effective control initiatives. But it still raises questions.

The majority of medications used to treat tuberculosis don’t work on many forms of the disease. For months, those with active tuberculosis must take a variety of drugs to treat the infection and prevent antibiotic resistance.

Different kinds of tuberculosis

You may also hear about several forms of TB, such as the most prevalent, pulmonary (lung) tuberculosis, in addition to active or inactive TB. But in addition to your lungs, the bacterium can also harm other parts of your body, leading to extrapulmonary tuberculosis (or TB outside of the lung). Additionally, systemic miliary TB, which can affect the entire body and result in:

  • Meningitis is a brain inflammation.
  • High quantities of white blood cells in your urine are referred to as sterile pyuria.
  • Spinal tuberculosis, often known as Pott’s disease or TB spondylitis.
  • an adrenal gland disorder called Addison’s disease.
  • The liver infection hepatitis.
  • Neck lymphadenitis, often known as scrofula or TB lymphadenitis.

Who is most at risk?

The majority of persons with tuberculosis are in their prime working years. All age groups, though, are in danger. In low- and middle-income nations, there are more than 80% of cases and fatalities.

Active TB is 18 times more likely to develop in HIV-positive people. Additionally, people with other immune-system compromising illnesses are more likely to have active TB. Undernourished individuals are three times as vulnerable. In 2021, there were 2.2 million new TB cases worldwide that could be linked to malnutrition.

Smoking and problematic alcohol use both raise the risk of TB. The causes of 0.74 million new cases of tuberculosis (TB) worldwide in 2021 were related to alcohol use disorders, while 0.63 million were related to smoking.

Symptoms of tuberculosis?

The majority of persons harbouring TB germs in their systems don’t develop TB disease. They actually still have a latent TB infection. If you have latent tuberculosis, you:

  • had no symptoms
  • cannot transmit TB to others
  • In the future, if your immune system deteriorates due to another factor, you could become ill with active TB illness.
  • Must take medication to avoid contracting active TB disease in the future

The TB bacteria are active if you have TB disease, which means they are growing (multiplying) inside of your body and making you ill. You can distribute the TB germs to other individuals if the disease is developing in your lungs or throat. TB disease can strike weeks to years after you’ve contracted the infection.

Your TB symptoms will depend on where the disease is spreading in your body.

Typical general signs include:

  • the flu with a fever
  • sweats at night (heavy sweating during sleep)
  • shedding pounds without trying
  • reduced appetite
  • weakness or exhaustion

Your lungs’ TB illness symptoms could include the following:

  • Cough that persists for more than three weeks
  • coughing up sputum or blood (a thick mucus from the lungs)
  • chest pain

What causes tuberculosis?

TB is brought on by a bacteria known as Mycobacterium tuberculosis. There are numerous TB strains, some of which have developed drug resistance.

Airborne droplets that are infected with the TB bacteria can spread the disease. Anyone around can breathe in these droplets once they are in the air. TB patients can spread the germs by:

  • sneezing
  • coughing
  • speaking
  • singing

Even if they have contracted the germs, people with healthy immune systems may not show signs of TB. Latent or dormant TB infection is what this is. Latent TB affects about one-fourth of all people on the planet.

Although latent TB is not contagious, it can eventually develop into an active illness. You can get sick from active TB disease and spread it to other people as well.

What are the precautions and warnings of Montair tablets?

What are the precautions and warnings of Montair tablets?

Comments 0 Comment

An anti-allergic drug called Montair is primarily used to treat asthma and seasonal allergies. An allergic reaction is an immune system reaction to outside substances that are usually not detrimental to your body. These alien substances are referred to as “allergens”. A localised inflammatory illness of the lungs and airways, asthma can cause excessive mucus production in response to certain stimuli such viruses, allergens, and exercise.

Montelukast, a component of Montair, is a leukotriene antagonist. Leukotriene, a chemical messenger, is blocked, which lowers inflammation and swelling of the lungs’ airways. Asthma episodes are avoided and breathing is made easier. When you have an allergic reaction to something like dust or pollen, leukotrienes are also generated in your body. Leukotriene levels are reduced by Montair, which also prevents your symptoms.

Medicinal Benefits

The anti-allergic drug Montair contains montelukast. As a leukotriene antagonist, montelukast lowers edoema and inflammation in the nose and lungs, improving symptoms and treating a wide spectrum of allergy disorders. As a result, symptoms including sneezing, runny nose, coughing, watery eyes, etc. are reduced. Asthma and allergy symptoms can be avoided with the use of this drug, which is referred to as a preventer.

How to use?

Take it as your doctor prescribes, whether with or without food. With a glass of water, swallow the entire tablet. Do not chew, break, or chew it. Tablets that can be chewed. Completely chew the tablet before swallowing. Do not consume it in its whole. Granules. Before using, take sure to read the label carefully. Mix the granules thoroughly with the milk or water before drinking right away.

Side Effects of Montair

  • Headache
  • abdominal pain
  • Body pain or pains
  • urine with pus
  • Anxiety and agitation
  • Heartburn Skin rash
  • distorted vision
  • respiratory infection
  • Face, lips, tongue, eyelids, hands, and feet swelling
  • Unwellness or vomiting
  • Diarrhoea
  • Fever

Precautions and Warning

If you are allergic to Montair or any of its constituents, avoid taking the medication. Before beginning Montair, let your doctor know if you have any mental disorders as it may cause mood changes (symptoms include anxiety, aggressive behaviour, irritability, restlessness).

At times, you could experience depression. If you experience any of these symptoms, let your doctor know. Avoiding contact with recognised allergens (agents that cause allergies), such as pollen, dust, etc., is advised. Allergies to particular foods have been documented. To decrease your mental alertness, Montair should not be taken with alcohol or other antidepressants. Do not stop taking Montair suddenly, even if you are asymptomatic and feeling fine. Doing so could cause an acute asthma attack.
