Migraine raises risk of dry eyes

Published

on

Suffering from migraine? You could be at higher odds of having chronic dry eye disease, says a new study. The chronic dry eye is a common disease in which natural tears fail to adequately lubricate the eyes, thus affecting its functioning and lessening a person’s quality of life.

The study showed that people with migraine had a 20% higher risk of having dry eye disease, the HealthDay reported. For men, aged 65 or above, having migraine nearly doubled the odds of dry eye disease, and risk in women of the same age was almost 2.5 times.

The association between migraine and dry eye was found to be more among the elderly, particularly for women due to hormonal changes caused by pregnancy, the use of oral contraceptives and menopause, the researchers said.

“Physicians caring for patients with a history of migraine headaches should be aware that these patients may be at risk for concurrent dry eye disease,” said Richard Davis, ophthalmologist at the University of North Carolina at Chapel Hill in the US.

For the study, the team examined 73,000 adults. The findings, published in the journal JAMA Ophthalmology, showed 8-34% of adults may be affected by dry eye disease.

Further, similar underlying inflammatory processes at the cellular level are known to play key roles in both dry eye disease and migraine.

“Inflammatory changes in dry eye disease might trigger similar events in neuromuscular tissue, leading to the development and propagation of migraine headaches,” the team noted.

Excessive dryness of the eye’s surface might work on key nerve pathways to help trigger migraines, they added. In addition, rheumatoid arthritis, diabetes, thyroid problems, exposure to smoke, wind and dry climates, and long-term use of contact lenses can also lead to dry eyes, the study noted.

Life expectancy in India drops by 2 years due to Covid pandemic: Report

Published

on

A statistical analysis conducted by Mumbai’s International Institute for Population Studies shows that life expectancy in India has dropped by roughly two years due to Covid-19 pandemic.

According to IIPS assistant professor Surayakant Yadav, the life expectancy at birth for men and women has declined from 69.5 years and 72 years in 2019 to 67.5 years and 69.8 respectively in 2020, reports Times of India.

‘Life expectancy at birth’ is defined as the average number of years that a newborn is expected to live if the mortality pattern during their birth remains constant in the future.

The study was conducted to analyse the effect of the Covid pandemic on the mortality patterns across the country, as thousands of lives were lost due to the deadly pandemic waves.

The study also found out that the Covid toll was reported to be the highest for men in the age group of 35-69. The excess deaths in this age bracket due to Covid led to a sharp drop in life expectancy.

The IIPS based its study on the data collected by the 145-nation Global Burden of Disease study and the Covid-India Application Programme Interface (API) portal.

Yadav further added, “The Covid impact has wiped out the progress we made in the last decade to increase the life expectancy figure. India’s life expectancy at birth now is the same as it was in 2010. It will take us years to catch up.”

However, IIPS director Dr K S James added that epidemics in the past in countries, including Africa, massively impacted life expectancy, but it recouped in a few years.

3rd Covid Wave Unlikely To Mirror Devastating 2nd Wave: Top Medical Body

Published

on

Rapid scale-up of vaccination efforts, says the study, could play an important role in mitigating the present and future waves of the disease.

New Delhi: A potential third wave of Covid infections seems unlikely to be as severe as the second wave, says a modelling study by a team of scientists from the Indian Council Of Medical Research (ICMR) and the Imperial College London, UK. Rapid scale-up of vaccination efforts, says the study, could play an important role in mitigating the present and future waves of the disease.

India’s first wave of SARSCoV-2 infection began in late January 2020 with a peak attained in mid-September. This phase was relatively mild compared to the second wave that followed, from mid-February 2021 onwards, exhibiting a more explosive spread across the country. A major factor driving this second wave is the emergence of more-infectious variants of SARS-CoV-2, principally B.1.1.7 (Alpha variant) and B.1.617.2 (Delta variant), of which the latter has played a dominant role in recent months.

Third waves have emerged in other countries – like the UK and the USA – and are driven by a range of factors, says the study.

The results suggest that a third wave, if it should occur, is unlikely to be as severe as the second wave, given the extent of spread that has already taken place in India, it adds.

“Consequently, for a virus to cause a major third wave in the face of this pre-existing immunity, extreme scenarios for the abrogation of that immunity are required, or for that matter, for the transmission fitness of any novel virus,” says the article in the Indian Journal of Medical Research.

For the wave to be as devastating, at least 30 per cent of the population who had been infected earlier must entirely lose their immunity, or an emerging variant of the virus must have a reproductive rate (R) over 4.5, that is, each infected person should be spreading to at least 4-5 others and these must occur almost immediately after the second wave ends, according to the study.

The emergence of a third wave in India could be substantially mitigated by the expansion of vaccination, says the study, adding the rollout of vaccine should be in such a way as to cover 40 per cent of the population with two doses over a period of three months following the end of the second wave, which is on the decline currently.

Crowding, use of mask and physical distancing during social interactions are all key factors shaping transmission rate and therefore population-level spread, the study cautions.

“Lockdown-release mechanisms could be a plausible driver for a third wave in India, depending on how effectively lockdowns have controlled transmission during the second wave particularly when instated at an early stage of the second wave and prior to attainment of peak,” says the study.

The analysis, says scientists, is intended to be illustrative and not predictive.

“In the present approach, we considered essentially a uniform waning rate over the spectrum of severity. Second, the basic reproduction number (equivalently, the rate-of-transmission) was assumed to remain constant during each wave,” said the scientists explaining the methodology used in the study.
