Aiming to harness Artificial Intelligence (AI) and deep learning methods for medical queries in the field of image banking, Indian Institute of Technology (IIT) Kharagpur and Tata Medical Center (TMC) have created an architecture image bio-bank to aid cancer research in the country, an official said on Saturday.
The bio-bank, named the Comprehensive Digital Archive of Cancer Imaging (CHAVI), will address the emerging field of imaging-related research. On the success of the pilot project, it can be scaled up to a larger set of medical images. Medical imagery can then be combined with AI to enable the reach of treatment to more people as well as provide targeted therapy based on individual symptoms.
IIT Kharagpur, through the National Digital Library Initiative (NDLI) of the Ministry of Human Resources and Development (MHRD), has joined hands in initiating a pilot project on developing an image data bank for cancer patients, and the present focus is on radio oncology. As a pilot, radiation oncology-related images are being banked within the NDLICHAVI RO project.
“The overarching aim is to build up a national bank of annotated images with a flexible query interface and link it with a pipeline of radiomic (extracting a large amount of features from radiographic medical images) services for furthering radiomic research in large image datasets,” the official said in a statement.
Also, TMC has created a large repository of medical data and images of cancer patients including outcomes of treatment in many cases. It faced various challenges while building this system. The first and foremost was preserving the anonymity of patients as well as maintaining adequate referential integrity, a necessity for carrying out useful research.
A workshop titled “Structuring a Collaborative National Image Banking Program” supported by MHRD through the NDLI project was organised here on Friday at TMC to enhance the CHAVI project. Several expert doctors from India, the US, the UK and specialists in the area of Computer Science from India participated in the panel discussions and presentations.
“We need more affordable solutions in India for cancer treatment, the majority of our patients are middle class and lower middle class and cannot afford genomic analysis. Image banking combined with predictive/prescriptive AI can enable us to identify signatures as a much more cost-effective alternative,” Sanjoy Chatterjee, TMC, Kolkata said.
Talking about the unique project, Partha Pratim Chakrabarti from NDLI said: “The CHAVI project is the first of its kind. The objective of the National Digital Library of India is to make accessible material for doing research that normally could not have been done in India. With the CHAVI project, as a beginning, we have chosen cancer imaging database along with Tata Medical Centre because of their tremendous expertise”.
“Cancer is one of the most dreaded diseases in our country. If we are able to create a very well defined, annotated database, it will help researchers as well as doctors to be able to do early, more accurate diagnosis and provide better treatment for our people which is a lot more cost-effective,” he added.

Some women say they experienced period changes after getting a Covid-19 vaccination. While the reported changes are short-lived, research into this possible adverse reaction remains critical to the success of the vaccination programme, according to an editorial published in The BMJ.
"A link between menstrual changes after Covid-19 vaccination is plausible and should be investigated," wrote Dr Victoria Male, a reproductive specialist at Imperial College London, in the editorial. Reports of menstrual changes after Covid-19 vaccination have been made for both mRNA and adenovirus-vectored vaccines, she added, suggesting that, if there is a connection, it is likely to be a result of the immune response to vaccination, rather than to a specific vaccine component, she said.
While changes to periods or unexpected vaginal bleeding are not listed as common side effects of Covid-19 vaccination, more than 30,000 such reports have been made to the UK Medicines and Healthcare Products Regulatory Agency (MHRA) surveillance scheme for adverse drug reactions till September 2. However, most people find that their period returns to normal the following cycleand, importantly, there is no evidence that Covid-19 vaccination adversely affects fertility, Male said.

The MHRA states that its surveillance data does not support a link between changes to menstrual periods and Covid-19 vaccines, since the number of reports is low in relation to both the number of people vaccinated and the prevalence of menstrual disorders generally. However, the way in which data is collected makes firm conclusions difficult, Male noted.
She argued that approaches better equipped to compare rates of menstrual changes in vaccinated versus unvaccinated populations are needed, and pointed to the study that the US National Institutes of Health (NIH) has undertaken. Indeed, the menstrual cycle may be affected by the body's immune response to the virus itself, with one study showing menstrual disruption in around a quarter of women infected with SARS-CoV2.
If a link between vaccination and menstrual changes is confirmed, this will allow individuals seeking vaccination to plan in advance for potentially altered cycles, Male contended. In the meantime, clinicians must encourage their patients to report any changes to periods or unexpected vaginal bleeding after vaccination. And anyone reporting a change in periods persisting over a number of cycles, or new vaginal bleeding after the menopause, should be managed according to the usual clinical guidelines for these conditions, she suggested.

A garage sale in the 21st century needs a tech-savvy platform. This is where Poshmark comes into the picture, the platform with a community of over 2.5 million Canadians has products listed with over half a billion dollars in value by their users.
It began expanding outside of the United States in Canada in May 2019 and has now launched in India. So its become simple and easy for anyone to sell items from their closet, enabled by a full suite of end-to-end seller tools and services, including seamless listing, merchandising, promotion, pricing, and shipping. Indian consumers will be able to join Social marketplace Poshmark, Inc. (Nasdaq: POSH), a booming community of more than 80 million users and a vibrant network of millions of shoppable closets to make money, save money, connect with others, and foster entrepreneurship.

Great historic events that have shaped the world and changed the outlines of countries are often not recorded in memory, or so we think. Wars made sure to destroy evidence and heritage, and the ones who survived told the tale of what really happened. Folklore, albeit through oral tradition kept alive many such stories, hidden in verse, limericks, and rhymes.
Ringa-ringa-roses, a common playtime rhyme among children across the world, is an example of folklore that has survived for many centuries. It tells the story of the The Great Plague of London which ravaged the city between 1665-1666.
The Plague broke out from improper disposal of garbage and poor sewage conditions. Fleas from the rats that lived in the sewers spread the disease that killed more than half of London's population. Many people fled from their homes as there was no medicine available for those who were infected.

It was around this time that masks began to be invented. The first masks were shaped like beaks, and were worn not to protect the wearer from the disease, but to the prevent them from being able to smell the decay and death around them, which they called 'miasma'. The beaks were filled with floral herbs that allowed doctors and nurses to tend to the sick without being reviled from the smell.
Children are often seen forming circles by holding hands and reciting loudly,
Pockets full of posies
We all fall down"

When the last line is sung, they break the circle and fall down. The roses and posies are believed to be the preferred fragrances inside the masks, and a single sneeze (a-tishoo) was enough to infect the one who was exposed to the disease. Consequently, they fell down, ill, and later died.
An alternative version of this rhyme is sung about the fall of Hiroshima and Nagasaki in the aftermath of World War II. The roses and posies are interchanged with geranium and uranium, to symbolise what was used in the atomic bomb. But this version is not as famous the original.
