Health Matters Newsletter: Safeguarding the windows to the soul
On cataract surgeries and the urgent need for access, brain and spine innovations, maternal health amidst rising heat, sickle cell care and more It's one of the most common surgeries performed, a procedure that practically everyone has heard of and perhaps one that most of us will have to undergo, but cataract surgeries are still not available and accessible to all -- cataracts continue to account for about 40% of all cases of existing blindness, and in India, remain the leading cause of blindness. In fact, as of 2023, the World Health Organization estimated that only 17% of people with vision impairment due to cataract have received access to an appropriate intervention. This, despite the surgery being one of the safest and least resource-intensive of procedures. We take our vision for granted most times, never really thinking about our eyes or how they work despite their being crucial to every aspect of our lives, but this June, observed as Cataract Awareness Month, is as good time a time as any, to learn and understand more about them. And to this end, we have two stories on cataract for you: Dr. S. Soundari explains the hows and whys of cataracts and the surgery required, and Dr. C. Aravinda and Dr. Sangeetha Raja give you a glimpse of the history and the evolution of the procedure that is now used to treat millions. Speaking of surgeries, here are a few more stories of interest, delving into medical procedures for the brain and spine: Dr. Ari G. Chacko explores advances in brain tumour care, while Dr. G. Sudhir and Dr. K. Karthik Kailash explain how minimally invasive spine surgery has transformed the landscape of spinal care. But in all of the excitement over the latest in medical science, the progress in technology and the potential promise of AI, it is crucial to not forget the basics: ensuring the health of mother and baby. And not only are we still some distance away from achieving optimal care for all mothers and babies in India, climate change is now emerging as an increased threat to the health of both. Take this into consideration: despite overall progress over the last 30 years, an analysis (published in the British Medical Journal Global Health) has found that cases of low weight at birth from four states -- Uttar Pradesh, Bihar, Maharashtra, and West Bengal -- account for nearly half of India's cases. Having a low birth weight -- under 2.5 kg -- has been linked with problems in the child's cognitive development and a vulnerability to chronic conditions in later life. To add to this existing issue is the burden of extreme heat: I podcast with Prof Jane Hirst about how high temperatures -- which India now faces on a regular basis -- impact pregnancy outcomes. Talking of maternal health, C. Mayareports that Kerala still has the lowest maternal mortality ratio (MMR) in the country despite some latest data revealing figures that the State disputes. And in Tamil Nadu, P. V. Srividya writes, the government's Pregnancy and Infant Cohort Monitoring and Evaluation system has helped exposechild marriages. Maternal health isn't just crucial at the time of pregnancy: Athira Elssa Johnsondecodes a study that found that domestic violence perpetrated on mothers was linked with higher depressive disorders amongst their teen children, highlighting again, the vital need to safeguard the health of mothers -- as this is intrinsically linked with the health of the next generation. One more story on newborns that can have far-reaching implication if made into policy is this study by the Indian Council of Medical Research that found post-birth diagnosis, resulting in early treatment, could substantially improve the quality of life and reduce mortality in patients with sickle cell disease -- from the reported current 20 to 30% to less than 5%. If you're wondering what sickle cell disease is, do read this explainer. Internationally too, there's been some focus on this area: British lawmakers have debated proposals to decriminalise abortion amid concerns that police are using antiquated laws to prosecute women who end their own pregnancies. Elsewhere around the globe, there's some good news, the United States' Food and Drug Administration (FDA) has approved of pharma company Gilead Sciences' twice-yearly injection to prevent HIV -- a move the company hailed as a major breakthrough in the fight against the sexually transmitted virus. Lenacapavir, marketed under the brand name Yeztugo, has been shown to reduce the risk of HIV transmission by more than 99.9 percent in adults and adolescents -- making it functionally akin to a powerful vaccine. Local news however, has been good, and not-so-good: while R. Prasadwrites on two existing drugs that offer hope to cure Russell's viper bites; Moyurie Som reports on the West Bengal Assembly passing a Bill on 'transparency' in medical costs in private facilities and Abhinay Lakshman details the Centre's plans to set up a National Tribal Health and Research Institute, Afshan Yasmeen speaks to the corresponding author of a research paper that has found that public health spending has not resulted in significant pro-poor services in India and S. Vijay Kumar finds that a report released by the Union Ministry of Health and Family Welfare has revealed that the organ transplantation programme in the country has been crippled by multiple issues, especially insufficient funding, shortage of specialised doctors, and procedural delays. Here's a quick round-up of the Covid-19 situation: cases are dipping, despite social media buzz about the 'razor blade' Covid variant, but even so, the ICMR has introduced its first high-performance computing facility at its National Institute of Virology (NIV) facility in Pune to boost genomic storage and analysis, aiding faster detection of new disease threats and more efficient response to outbreaks. Our tailpiece for the week is this story by Dr. Vid Karmarkar and Jitendra Chouksey on why alcohol regulation in India needs a national framework and policy. Once again, we have a healthy list of explainers this week, do dive in when you find the time: Dr. Arunima Ray writes on understanding albinism in the Indian context Dr. Javeed Zabiullah explains why the world needs to embrace neurodiversity Dr. V. Madhumitha busts myths around vitiligo Dr. Raman Goel writes on the importance of changing mindsets and narratives around obesity Dr. Arun Kumar Balakrishnan details the need to screen for kidney cancer after 40 Anirban Mukhopadhyay breaks down a study on making CAR T-cells in vivo for cancer care If you want to know about DNA analysis, click here As part of our 'all you need to know' series, here is an explainer on the world's rarest blood group, Gwada negative, and one on clinical trials And finally, here is why chronic pain must be part of suicide risk assessments For many more health stories, head to our health page and subscribe to the health newsletter here.
