"Psoriasis is affecting millions globally, influencing not only skin health but also joints, overall immunity, and mental well-being," says Dr. Prachi B Bodkhe, dermatologist at Envi Aesthetics. "Though a cure can’t be promised, this condition can be effectively managed with medical supervision, lifestyle changes, and awareness of associated conditions," she adds.It is important that patients avoid self-medication. As Bodkhe explains, "Psoriasis management is complex, and treatments that work for one person may be harmful or ineffective for another." Following your care provider’s guidance, undergoing tests when recommended, and adopting a healthy lifestyle can help reduce recurrence and prolong remission. This World Psoriasis Month, dermatologists delve into early signs to watch out for, ...

Abdominal obesity coupled with greater sedentary behaviour is a driving factor for an early and more aggressive risk of diabetes among South Asians, including Indians, revealed a study on Tuesday.  The study, published in the BMJ, explored the characteristics of type 2 diabetes in South Asians who tend to develop the condition at a younger average age and lower body mass index than the white population. “South Asians face type 2 diabetes earlier and more aggressively than most other populations. Our review shows that diabetes often begins at lower body weight, progresses rapidly, and leads to more complications (kidney disease, heart attacks),” endocrinologist Dr. Anoop Misra, Director of Diabetes Foundation (India), who led the study, told IANS. The study, in collaboration with researc...

Bloodstream infections acquired during a hospital stay due to the use of a catheter are prevalent across ICUs in India and are often caused by microbes having a high level of antibiotic resistance, according to a study led by the All India Institute of Medical Sciences, New Delhi. Antibiotic resistance -- in which antibiotic drugs are rendered ineffective because disease-causing microbes have become immune to them -- can extend one`s hospital stay and treatment costs, adding stress to a public healthcare system. Estimates published in The Lancet Global Health journal show that on average, around nine bloodstream infection events occur every 1,000 days that a central line -- a catheter inserted in a patient`s large vein instead of an intravenous line -- was in place in the intensive care ...

In a first, a team of Australian scientists has grown the world`s first fully functioning lab-made human skin with its own blood supply. The advance may pave the way for better treatment of skin diseases, burns, and grafts.  The team from the University of Queensland used stem cells to create a replica of the human skin, which had blood vessels, capillaries, hair follicles, nerves, tissue layers, and immune cells. "This is the most life-like skin model that`s been developed anywhere in the world and will allow us to study diseases and test treatments more accurately," said lead researcher Abbas Shafiee, a tissue engineering and regenerative medicine scientist from UQ`s Frazer Institute. “Until now, scientists have been limited in how we study skin diseases and develop new therapies. “B...

The productivity of workers in extreme heat drops by two to three per cent for every degree above an ambient temperature of 20 degrees Celsius, highlights a report brought out by the United Nations` health and climate agencies. Analysing evidence from studies from past five decades that "have provided conclusive evidence that workplace heat stress directly threatens workers` ability to live healthy and productive lives", the World Health Organization (WHO) and World Meteorological Organization (WMO) have also outlined guidance on how the growing risks of heat can be mitigated in the section of society. Extreme heat events around the world occur more often and have become intense, increasing risks for both outdoor and indoor workers, authors of the report say, adding that related health r...

Researchers at the Indian Institute of Technology (IIT) Roorkee have developed HyEco -- a first-of-its-kind integrated flood-water quality modelling platform which shows how potential disease-causing microbes can travel in floodwaters and where people are most at risk of getting affected.  This novel framework, which also predicts how urban flood waters will spread across a city, was tested during the 2023 Delhi floods. The results were alarming; over 60 per cent of flooded areas were in the high to very high danger zones, and harmful bacteria (E. coli) in the water were found to be hundreds of thousands of times above safe limits. Children, in particular, faced infection risks more than double the internationally accepted safety levels when playing in floodwaters. Floodwaters in many ...

Omega fatty acids could protect against Alzheimer’s disease in women, new research showed on Wednesday, August 20.  Scientists from the UK’s King’s College London and Queen Mary University London conducted an analysis of lipids -- fat molecules that perform many essential functions in the body -- in the blood. They found a noticeable loss of unsaturated fats, such as those that contain omega fatty acids, in the blood of women with Alzheimer’s disease compared to healthy women. They found no significant difference in the same lipid molecule composition in men with Alzheimer’s disease compared to healthy men, which suggests that those lipids have a different role in the disease according to sex. Fats perform important roles in maintaining a healthy brain, so this study could indicate why m...

A continued global warming could bring down the world`s emotional well-being by 2.3 per cent by 2100, according to a study that shows how climate change threatens one`s daily experience and not just health and economic stability. Researchers from the Chinese Academy of Sciences and Massachusetts Institute of Technology, among others in the US, analysed 1.2 billion social media posts of 2019 from 157 countries. Findings published in the journal One Earth show that daily maximum temperatures above 35 degrees Celsius can worsen people`s emotional well-being, with poorer countries impacted disproportionately -- almost thrice -- compared to richer ones. Policymakers cannot truly assess the social costs of climate change or design equitable interventions to protect citizens` physical and psyc...

Adults in the national capital inhale almost twice as many microplastic particles in summer as they do in winter, with the estimated average daily exposure rising from 10.7 particles in the colder months to 21.1 in the hotter season -- a 97 per cent jump, according to a new study. The study, titled `Characterization and Health Risk Assessment of Airborne Microplastics in Delhi NCR`, a joint effort by researchers from the Indian Institute of Tropical Meteorology (IITM), under the Ministry of Earth Sciences, and the Department of Environmental Sciences at Savitribai Phule Pune University, said children and toddlers also face significant exposure. Children aged 6 to 12 inhale about 8.1 particles a day in winter, rising to 15.6 in summer, while toddlers aged between one to six breathe in 6.1...

A diet rich in omega-3 fatty acids is not only good for adults, but also crucial to ward off the development of shortsightedness (myopia) in children, according to a global study. Omega-3 polyunsaturated fatty acids (ω-3 PUFAs), which can only be obtained from the diet -- found predominantly in fish oils -- are thought to improve or prevent several chronic eye conditions, including dry eye disease and age-related macular degeneration. But whether they can help ward off myopia wasn`t clear, as studies to date have been experimental and haven`t included people. "This study provides the human evidence that higher dietary ω-3 PUFA intake is associated with shorter axial length and less myopic refraction, highlighting ω-3 PUFAs as a potential protective dietary factor against myopia developm...
