Dogs may accurately sniff out cancer in blood

Published

on

Dogs can use their highly evolved sense of smell to pick out human blood samples with cancer with almost 97% accuracy, according a a study that may lead to inexpensive and non-invasive screening approaches for the deadly disease.

Dogs have smell receptors 10,000 times more accurate than humans, making them highly sensitive to odours we can’t perceive, said researchers who presented the study at the American Society for Biochemistry and Molecular Biology annual meeting in Florida, US.

“Although there is currently no cure for cancer, early detection offers the best hope of survival,” said Heather Junqueira, lead researcher at the US-based healthcare company BioScentDx.

“A highly sensitive test for detecting cancer could potentially save thousands of lives and change the way the disease is treated,” Junqueira said in a statement.

The researchers used a form of clicker training to teach four beagles to distinguish between normal blood serum and samples from patients with malignant lung cancer.

Although one beagle was unmotivated to perform, the other three dogs correctly identified lung cancer samples 96.7% of the time and normal samples 97.5% of the time.

“This work is very exciting because it paves the way for further research along two paths, both of which could lead to new cancer-detection tools,” said Junqueira.

“One is using canine scent detection as a screening method for cancers, and the other would be to determine the biologic compounds the dogs detect and then design cancer-screening tests based on those compounds,” she said.

BioScentDx plans to use canine scent detection to develop a non-invasive way of screening for cancer and other life-threatening diseases.

Munmun in her caption wrote, “Great part was, at long last after not turning out for right around 4 months, I got once more into the propensity for working out routinely once more. Long approach to accomplish the god-like physique however I am on target and persuaded to do as such. It will be an excursion and I am anticipating it.”

As of late, Munmun had purchased another level in Mumbai and shared photographs of it via online media. She said that purchasing the new house was a “little glimpse of heaven” second for her.

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.
