Researchers have identified that multiple CT findings can identify patients with high-risk non-alcoholic fatty liver disease (NAFLD) — advanced fibrosis or cirrhosis, that is — though the presence of non-alcoholic steatohepatitis (NASH) remains elusive on CT.

Fibrosis, also known as fibrotic scarring, is a pathological wound healing in which connective tissue replaces normal parenchymal tissue to the extent that it goes unchecked, leading to considerable tissue remodelling and the formation of permanent scar tissue.


And, cirrhosis is a late stage of scarring (fibrosis) of the liver caused by many forms of liver diseases and conditions, such as hepatitis and chronic alcoholism.

“Subjective assessment of multiple morphologic and separately quantified parameters by trained readers and a simple quantitative three-parameter model combining two CT features, liver surface nodularity (LSN) and liver segmental volume ratio (LSVR), and a clinical score (FIB-4) showed good association with the presence of advanced fibrosis,” said researcher Meghan G. Lubner from the University of Wisconsin in the US.

For the study, the research team included a total of 186 patients with NAFLD (mean age, 49 years; 74 men and 112 women), of whom 87 (47 per cent) had nonalcoholic steatohepatitis (NASH) and 112 (60 per cent) had moderate to severe steatosis.

An experienced gastrointestinal pathologist performed a histopathologic review to determine steatosis, inflammation, and fibrosis.

The presence of any lobular inflammation and hepatocyte ballooning was categorized as nonalcoholic steatohepatitis (NASH), while patients with NAFLD and advanced fibrosis (stage F3 or higher) were categorized as having high-risk NAFLD. Two readers subjectively assessed the presence of NASH and fibrosis.

The researchers found that a total of 51 patients were classified as fibrosis stage F0, 42 as F1, 23 as F2, 37 as F3, and 33 as F4.

Additionally, 70 (38 per cent) had advanced fibrosis (stage F3 or F4) and were considered to have high-risk NAFLD. FIB-4 score showed a correlation with fibrosis, and of the individual CT parameters, LSVR and splenic volume had the best performance. Meanwhile, subjective reader assessment performed best among all parameters. FIB-4 and subjective scores were complementary, and for NASH assessment, FIB-4 performed best.

Noting the well-established utility of CT in identifying hepatic steatosis, the authors of this AJR article concluded that CT can also be “a highly accessible, frequently used method for assessment of patients with NAFLD and identification of those with high-risk NAFLD (advanced fibrosis or cirrhosis) who are potentially most in need of intervention,” the researcher said.

Narakasura's death is celebrated as 'Naraka Chaturdashi' popularly known as Choti Diwali

Diwali is arguably one of the most auspicious and celebrated holidays in South Asia. It is celebrated over the span of five days, where the third is considered most important and known as Diwali. During Diwali people come together to light, lamps, and diyas, savour sweet delicacies and pray to the lord. The day has various origin stories with the main them being the victory of good over evil. While the North celebrates the return of Lord Rama and Devi Sita to Ayodhya, the South rejoices in the victory of Lord Krishna and his consort Satyabhama over evil Narakasura.

Narakasura- The great mythical demon King

Naraka or Narakasur was the son of Bhudevi (Goddess Earth) and fathered either by the Varaha incarnation of Vishnu or Hiranyaksha. He grew to be a powerful demon king and became the legendary progenitor of all three dynasties of Pragjyotisha-Kamarupa, and the founding ruler of the legendary Bhauma dynasty of Pragjyotisha.

Safety-pins with charms

For all the great inventions that we have at hand, it is amazing how we keep going back to the safety pin every single time to fix everything. Be it tears in our clothes, to fix our broken things, to clean our teeth and nails when toothpicks are unavailable, to accessorize our clothes, and of course, as an integral part of the Indian saree. Safety pins are a must-have in our homes. But how did they come about at all?

The safety pin was invented at a time when brooches existed. They were used by the Greeks and Romans quite extensively. A man named Walter Hunt picked up a piece of brass and coiled it into the safety pin we know today. He did it just to pay off his debt. He even sold the patent rights of this seemingly insignificant invention just so that his debtors would leave him alone.

Sesame oil bath is also called ennai kuliyal in Tamil

In South India, Deepavali marks the end of the monsoon and heralds the start of winter. The festival is usually observed in the weeks following heavy rain, and just before the first cold spell in the peninsula. The light and laughter that comes with the almost week-long celebration are certainly warm to the bones, but there is still a tradition that the South Indians follow to ease their transition from humidity to the cold.

Just before the main festival, the family bathes in sesame oil. This tradition is called 'yellu yennai snaana' in Kannada, or 'ennai kuliyal' in Tamil, which translates to 'sesame oil bath'. The eldest member of the family applies three drops of heated oil on each member's head. They must massage this oil into their hair and body. The oil is allowed to soak in for a while, anywhere between twenty minutes to an hour. After this, they must wash with warm water before sunrise.
