First malaria treatment for newborns approved with significant economic implications for Africa
The approval of the first-ever malaria treatment for newborns has substantial long-term economic potential for affected African nations, according to a report in The Washington Post. The treatment targets a key demographic, as children under five in the WHO's Africa region accounted for 76% of the 597,000 global malaria deaths in 2023. From an economic perspective, this development is poised to enhance human capital by improving child survival rates and long-term health outcomes. A healthier population can lead to increased productivity and free up household resources that would otherwise be spent on healthcare. The approval also validates the investment models of global health initiatives, potentially encouraging further public-private partnerships. However, realising these economic benefits is contingent on overcoming logistical hurdles, including ensuring equitable distribution and affordability, which will require regulatory approval and investment from national governments.

'Misleading': Centre rejects Swiss firm's pollution rankings; cites limited government data usage by report
NEW DELHI: The central government on Thursday rejected the Swiss firm's IQAir report, that had ranked India the fifth most polluted country in the world, citing limited usage of government data in the survey. Tired of too many ads? go ad free now "However, it must be noted that only 38 per cent of the data sources used in the report are from government agencies. The remaining 62 per cent are from other agencies and include data generated using low-cost sensors," Union minister of state for environment Kirti Vardhan Singh said responding to a question by Congress MP Pramod Tiwari in the Rajya Sabha. "The data from a variety of monitors and sources, especially low-cost sensors, may have inaccuracies. Moreover, the report uses population-weighted averages based on data from urban monitoring stations, which may not represent the true national average," the minister said. "In view of these limitations and uncertainties in the data, the ranking of cities and countries may not portray the true picture and could be misleading," he added. In response to a query on whether air pollution is causing deaths and affecting public health nationwide, the minister said there is no conclusive data to establish a direct link between air pollution and mortality. "Air pollution is one of many contributing factors that can affect respiratory ailments and related diseases. Health is determined by several variables, including food habits, occupational exposure, socio-economic conditions, medical history, immunity, heredity and environmental factors," Singh said. According to IQAir's 2024 World Air Quality Report, India ranked as the fifth most polluted country in the world based on air quality data. The report named Byrnihat in Meghalaya as the most polluted metropolitan area globally, with an annual average PM2.5 concentration of 128.2 µg/m³, over 25 times higher than the WHO-recommended limit and more than three times the national standard.

Can genetics predict obesity? New study may help spot risk in kids before it is too late
Synopsis A new study introduces ancestry-specific polygenic risk scores that double the effectiveness of predicting adult obesity risk compared to current methods. Analyzing genetic data from over 5 million individuals, the tool identifies those at risk early in childhood. While genetics play a role, lifestyle and environmental factors remain crucial in addressing the global obesity epidemic. iStock A new study introduces ancestry-specific polygenic risk scores that double the effectiveness of predicting adult obesity risk compared to current methods. (Image :iStock) Imagine knowing whether your child may be at risk for obesity—not years after weight gain begins, but long before it shows. A groundbreaking new study published in Nature Medicine suggests this could soon be possible, thanks to a genetic tool called polygenic risk scores (PGS).Led by over 600 scientists from 500 institutions worldwide, and drawing data from The Genetic Investigation of ANthropometric Traits (GIANT) consortium and 23andMe, the study analyzed genetic information from more than 5 million individuals. Their goal? To develop a more precise way to predict a person's likelihood of developing obesity, starting from childhood. Current obesity risk tools largely rely on family history, diet, and lifestyle. But this study's new ancestry-specific and multi-ancestry polygenic risk scores proved about twice as effective in predicting obesity in adulthood compared to existing people of European ancestry, for example, the score accounted for 17.6% of an individual's risk of developing a high Body Mass Index (BMI)—a key indicator of obesity. The study included a broad participant base: 70% had European ancestry, 14.4% were Hispanic, 8.4% East Asian, 4.6% African, and 1.5% South while the tool is promising, it isn't a crystal ball. 'Obesity is not only about genetics,' said Dr. Ruth Loos, study co-author and professor at the University of Copenhagen's Novo Nordisk Foundation Center, in an interview with NBC News. 'Genetics alone can never accurately predict obesity… other factors, such as lifestyle, need to be part of the predictions.' The urgency behind such research is clear. Obesity is now considered one of the world's fastest-growing public health threats. According to World Health Organization (WHO) data: In 2022, 2.5 billion adults were overweight, including over 890 million with obesity. Childhood obesity is skyrocketing—35 million children under five were overweight in 2024, and over 390 million adolescents aged 5–19 were overweight in 2022. Obesity was a factor in 3.7 million global deaths in 2021 alone. Perhaps more troubling is the shift in obesity prevalence from wealthier nations to low- and middle-income countries, where children face a 'double burden' of both undernutrition and rising obesity rates. The WHO warns that these children often live in environments where high-calorie, nutrient-poor foods are cheap and accessible, but healthier choices and safe spaces for exercise are is much more than a number on a scale. It increases the risk of nearly 200 diseases, including type 2 diabetes, cardiovascular disease, asthma, and certain cancers. For children, the stakes are even higher: obesity not only impacts their physical and mental health but also academic performance and social wellbeing due to stigma and childhood obesity often carries into adulthood, setting the stage for chronic illness and shorter lifespans. 'Children with obesity are very likely to be adults with obesity,' notes the WHO. While genetic scores like the one developed in this study could revolutionize early detection, experts caution that there's no one-size-fits-all solution. Dr. Karen Hacker, director of the CDC's National Center for Chronic Disease Prevention, told USA TODAY that effective obesity prevention must address broader social determinants of health—including access to healthcare, nutritious food, physical activity, and Centers for Disease Control and Prevention (CDC) recommends multifaceted strategies: from medication and surgery for treatment, to policy-driven efforts ensuring access to healthy food, safe physical environments, and stigma-free support systems.
