New York - Researchers have found that patients with asthma do not seem to be at risk from complications associated with being hospitalised with Covid-19 disease.
The study, published in the journal Annals of the American Thoracic Society, examined whether asthma is a significant risk factor for developing Covid-19 that is severe enough to warrant hospitalisation and intubation.
"The Centers for Disease Control and Prevention (CDC) places people with asthma at higher risk for Covid-related hospitalisation," said study researcher Fernando Holguin from the University of Colorado Anschutz in the US.
"However, many international studies show low numbers of asthmatics among hospitalised Covid-19 patients. These findings challenge the assumption about asthma as a risk factor," Holguin added.
For the findings, the research team compared the prevalence of asthma among patients hospitalised for Covid-19, as reported in 15 peer-reviewed studies, with that of the corresponding population's asthma prevalence.
They also correlated the study's asthma prevalence with the four-year average asthma prevalence in influenza hospitalisations in the US.
In addition, they analyzed the medical records of 436 Covid-19 patients admitted to the University of Colorado Hospital to evaluate the likelihood that patients with asthma would be intubated more often than patients without asthma.
The researchers also performed a focused review of English-language scientific literature in order to identify studies reporting asthma prevalence among patients hospitalised for Covid-19 infection.
Three independent reviewers agreed on 15 studies to include in the analysis.
Using local data from hospitalised Covid-19 patients, they performed a statistical analysis to determine the relationship between asthma status and intubation, once they took into account patients' age, gender and body mass index (BMI).
"We found that the proportion of asthmatics among hospitalised patients with Covid-19 is relatively similar to that of each study site's population asthma prevalence," the authors wrote.
This finding is in stark contrast to influenza, in which asthmatics make up more than 20 per cent of those hospitalised in the US," they added.
"Using data from our hospital, we also observed that among Covid-19 patients, those with asthma, which had a 12 per cent prevalence rate, did not seem to be more likely to be intubated than non-asthmatics," the team noted.
The research team theorised that the corticosteroid inhalers many people with asthma use make it more difficult for coronaviruses to enter their airways.
London, Aug 20 (IANS) Researchers have warned that children exposed to higher levels of fine particles in the air (known as PM2.5) are more likely to develop asthma and persistent wheezing than children who are not exposed.According to the study, published in the journal BMJ, PM2.5 can come from various sources, including power plants, motor vehicles and domestic heating.The particles (about 3 per cent or less of the diameter of a human hair) can penetrate deep into the lungs and some may even enter the circulatory system. "These findings support emerging evidence that exposure to air pollution might influence the development of asthma," said the study authors from the Aarhus University in Denmark.Short term peak exposure to air pollution has been associated with worsening of asthma, whereas the risks of long term exposure and the timing of exposure for the onset of asthma is less clear.In addition, the role of air pollution combined with other risk factors, such as socioeconomic status, on asthma is unclear so researchers in Denmark set out to identify risk factors (air pollution and family-related) for the onset of asthma and persistent wheezing in children.Their findings are based on more than three million Danish children born from 1997 to 2014 and followed for asthma onset and persistent wheezing from age one year to 15 years.Of these, 122,842 children were identified as having asthma and persistent wheezing (at an average age of 1.9 years).This information was then linked to detailed air pollutant measurements at the children's home addresses, parental asthma, maternal smoking, parental education and income.After taking account of other potentially influential factors, the researchers found higher levels of asthma and persistent wheezing in children of parents with asthma and in children of mothers who smoked during pregnancy.In contrast, lower levels of asthma and persistent wheezing were found in children of parents with high educational attainment and high incomes.Exposure to PM2.5 as well as larger particulate matter (PM10) NO2 and nitrate was associated with an increased risk of asthma and persistent wheezing. However, only the positive association of PM2.5 with asthma and persistent wheezing remained robust across the different models and after further (sensitivity) analyses.The researchers point to some limitations, such as a lack of information on nutrition and physical activity, and factors related to the children's indoor environment.--IANSbu/rt/bg
Toronto, July 6 (IANS) Dear parents, if your teenage child is not going to bed early and is hooked to screen late in night, read this carefully.Researchers, including one of Indian-origin, have found that teenagers who prefer to stay up late and wake later in the morning are more likely to suffer from asthma and allergies compared to those who sleep early.Asthma symptoms are known to be strongly linked to the body's internal clock, but this study, published in ERJ Open Research, looked at how individual sleep preferences influence asthma risk in teenagers.According to the researchers, the study reinforces the importance of sleep timing for teenagers and opens up a new channel of research into how sleep affects teenagers' respiratory health."Sleep and the 'sleep hormone' melatonin are known to influence asthma, so we wanted to see if adolescents' preference for staying up late or going to bed early could be involved in their asthma risk," said Subhabrata Moitra from the University of Alberta in Canada.The study involved 1,684 adolescents living in West Bengal, India, aged 13 or 14 years, who were taking part in the Prevalence and Risk Factors of Asthma and Allergy-Related Diseases among Adolescents (PERFORMANCE) study.Each participant was asked about any wheezing, asthma, or symptoms of allergic rhinitis, such as a runny nose and sneezing. They were asked a series of questions to judge whether they were 'evening types', 'morning types' or in between, such as what time of the evening or night they tend to feel tired, when they would choose to wake up, and how tired they feel first thing in the morning.Researchers compared the teenagers' symptoms with their sleep preferences, taking into account other factors that are known to affects asthma and allergies, such as where the participants live and whether their family members smoke.They found that the chance of having asthma was around three times higher in teens who prefer to sleep later compared to those who preferred to sleep earlier. They also found the risk of suffering allergic rhinitis was twice as high in late-sleepers compared to early-sleepers."Our results suggest there's a link between preferred sleep time, and asthma and allergies in teenagers," Moitra said."We can't be certain that staying up late is causing asthma, but we know that the sleep hormone melatonin is often out of sync in late-sleepers and that could, in turn, be influencing teenagers' allergic response," Moitra informed.--IANSbu/rs/
मौजूदा महामारी में सेहत व स्वास्थ्य को महत्व देना होगा। यह खासकर तब बहुत जरूरी है, जब आपकी प्रतिरक्षा प्रणाली कमजोर है या फिर आपको किसी बीमारी का इतिहास है। अस्थमा इन्हीं में से एक है। अस्थमा बिगड़ने का मुख्य कारण श्वास की नली में वायरल संक्रमण होना है। अस्थमा के जोखिम वाले लोगों या फिर मौजूदा अस्थमा पीड़ितों के लिए सांस की नली में वायरल संक्रमण बहुत घातक हो सकते हैं। एक अनुमान के अनुसार सामान्य या फिर गंभीर अस्थमा के मरीजों को बीमारी के और ज्यादा गंभीर होने का खतरा ज्यादा होता है।
भारत में लगभग 9.3 करोड़ लोग सांस की क्रोनिक समस्या से पीड़ित हैं। इनमें से लगभग 3.7 करोड़ एस्थमेटिक हैं। अस्थमा के वैश्विक भार में भारत का हिस्सा केवल 11.1 प्रतिशत है, जबकि विश्व में अस्थमा से होने वाली मौतों में भारत का हिस्सा 42 प्रतिशत है, जिस वजह से भारत दुनिया की अस्थमा कैपिटल बन गया है।
अपोलो अस्पताल के कंसलटेंट स्पेशलिस्ट (चेस्ट मेडिसिन, क्रिटिकल केयर मेडिसिन एंड स्लीप मेडिसिन) डॉक्टर रोहित करोली के अनुसार, "अस्थमा पर सांस के वायरस के प्रभाव के चलते यह बहुत आवश्यक हो गया है कि मौजूदा समय में अस्थमा पीड़ित बहुत ज्यादा सावधानी बरतें। वायरस निर्मित समस्याओं की रोकथाम के लिए अस्थमा को अच्छी तरह से नियंत्रित करना बहुत आवश्यक है।"
मौजूदा महामारी के समय में किसी बीमारी के उपचार के लिए आपातकालीन विभाग या अत्यावश्यक इलाज के लिए जाना पड़ता है ,जहां पर मरीज को किसी संक्रमित व्यक्ति के संपर्क में आने का जोखिम भी ज्यादा होता है।
गाजियाबाद के नरेंदर मोहन हॉस्पीटल के सीनियर कंसलटेंट (चेस्ट स्पेशलिस्ट) डॉक्टर मनीष त्रिपाठी के अनुसार, "अस्थमा पीड़ितों को अस्थमा नियंत्रित रखने के लिए स्टेरॉयड इन्हेलर्स दिए जाते हैं। अस्थमा पीड़ितों को कभी भी अपने कॉर्टिकोस्टेरॉयड इन्हेलर तब तक लेना बंद नहीं करना चाहिए, जब तक कोई मेडिकल प्रोफेशनल उनसे ऐसा करने को न कहे। स्टेरॉयड इन्हेलर का प्रयोग बंद करने से मरीज को संक्रमण का ज्यादा खतरा हो जाएगा क्योंकि इससे अस्थमा का नियंत्रण खराब हो जाता है।"
यदि अस्थमा नियंत्रण में है, तो हॉस्पिटल के क्लिनिक जाने से बचें। आप टेलीफोन पर अपने डॉक्टर से संपर्क कर सकते हैं और उन्हें अपनी प्रगति के बारे में बता सकते हैं। एस्थमेटिक मरीजों को बिना योजना के क्लिनिक नहीं जाना चाहिए। सामान्य से गंभीर अस्थमा से पीड़ित लोगों को वायरल संक्रमण से बहुत ज्यादा बीमारी पड़ने का खतरा रहता है। ये संक्रमण आपकी सांस की नली (नाक, गला, फेफड़ों) को प्रभावित करते हैं, अस्थमा का अटैक लाते हैं और इनकी वजह से निमोनिया या एक्यूट रेस्पिरेटरी डिजीज हो सकती है।
एक्यूट लक्षणों से आराम के लिए स्पेसर के साथ एमडीआई का उपयोग किया जा सकता है। नेबुलाईजर्स का उपयोग करने से बचें क्योंकि उनमें वायरल संक्रमण फैलने का खतरा बहुत ज्यादा होता है। नेबुलाईजर्स एयरोसोल्स बनाते हैं, जो संक्रमित ड्रॉपलेट्स को कई मीटर तक फैला सकते हैं।
आपका डॉक्टर आपको इन विधियों के बारे में परामर्श देगा। सुनिश्चित करें कि आपके पास नॉन-प्रेस्क्रिप्शन दवाईयों एवं सप्लाई का 30 दिनों का स्टॉक हो, ताकि यदि लंबे समय तक आपको घर में रहने की जरूरत पड़े, तो आपको कोई परेशानी न हो।
Panaji, June 22 (IANS) As Goa reported its first Covid-19 death after an 85-year-old man died on Monday morning, Chief Minister Pramod Sawant said the patient was suffering from asthma and diabetes."He was a diabetic, asthamatic and had comorbid conditions. He was admitted to the Goa Medical College in serious condition on Sunday. After he tested positive, he was admitted to the Covid-19 hospital. He was on ventilator," Sawant told reporters in Panaji."Because of the age factor and co-morbid conditions, I feel we could not do much," the Chief Minister said.Earlier, Health Minister Vishwajit Rane condoled the death of the patient, who hailed from Morlem, a remote village located at the foothills of the Western Ghats."Deeply saddened to inform that a 85-year-old man, from Morlem in Sattari, has succumbed to COVID-19. My heartfelt condolence to the family," Rane tweeted.Goa currently has 683 active coronavirus cases.--IANSmaya/tsb
New York- A good night's sleep is crucial to good health because researchers have found that too little sleep, and occasionally too much sleep, can negatively impact adults with asthma.
Previous research revealed that poor sleep quality has a negative effect on asthma symptoms in adolescents.
"Our study shows that adults with asthma are equally affected by too little (or sometimes too much) sleep," said study lead author Faith Luyster from the University of Pittsburgh in the US.
Compared to normal sleepers, short and long sleepers had a higher proportion of people who reported having an asthma attack in the past year (45 per cent vs. 59 per cent and 51 per cent respectively) and had more days with impaired health-related quality of life.
According to the researchers, impaired quality of life was characterised by more days of poor physical and mental health.For the findings, published in the journal Annals of Allergy, Asthma and Immunology, the research team surveyed 1,389 adults who were 20 years and older who self-identified as having asthma.A Of the group, 25.9 per cent slept 5 hours or less, 65.9 per cent slept 6-8 hours and 8.2 per cent slept 9 or more hours
Sleep duration was measured by a single question, "How much sleep do you usually get at night on weekdays or workdays?"
"Short sleepers" were more likely to be younger and non-White, while "long sleep were more likely to be older, female and a smoker. Short sleepers, as compared to normal sleepers, had a greater likelihood of an asthma attack, dry cough, and an overnight hospitalisation during the past year.
Short sleepers also had the significantly worse health-related quality of life -- including days of poor physical and mental health and inactive days due to poor health -- and more frequent general healthcare use during the past year as compared to normal sleepers.
"This study adds solid evidence to the practice of asthma patients discussing sleep issues with their allergist to help determine if they need to change their asthma plan to achieve adequate sleep as a component of overall good asthma management," said Gailen D Marshall, Editor-in-Chief of Annals Journal.
