For over 15 years, Dr Anthony Shum, a pulmonologist at the University of California, San Francisco has been studying a rare genetic disorder called the COPA Syndrome. It stands for coatomer subunit alpha and is a rare, inherited disorder that affects the lungs, joint, and kidney. The National Organization for Rare Disorder also notes that it is a genetic autoimmune disorder that is caused by mutations in the COPA gene. This disease affects families unpredictably—some individuals with the mutation develop severe lung damage early in life, while others remain completely healthy. Now, Shum’s team has discovered a protective genetic variant that may offer new hope for treatment.

A Breakthrough

Researchers found that some relatives of COPA Syndrome patients stayed healthy despite carrying the same COPA gene mutation that causes the disease. The key difference? These unaffected individuals had a protective version of another gene called HAQ-STING.

When scientists introduced HAQ-STING into diseased lung cells from COPA patients, the cells returned to a balanced state, suggesting that this gene could be used as a therapy.

“We really think HAQ-STING could be a gene therapy tool and a step toward a cure,” said Shum, whose findings were published in the Journal of Experimental Medicine.

Families Who Solved The Mystery

Shum’s journey into COPA Syndrome research began in 2011 when he treated a young woman, Letasha, who had severe lung bleeding. Her mother, Betty Towe, mentioned that Letasha’s sister, Kristina, had suffered from similar symptoms. Over the years, Betty had taken both daughters on a four-hour trip to UCSF for treatment. After tracing their family history, Shum discovered that their distant relatives in Texas and Oakland also had lung problems and arthritis. In 2015, Shum, along with scientists from Baylor College of Medicine and Texas Children’s Hospital identified the COPA gene mutation. They realized that it was the common factor behind the illness. However, only some of the 30 individuals with the mutation actually developed symptoms, leaving a major question unanswered.

The Domino Effect

It was established that it occurs when a mutated COPA gene causes another gene STING to go overdrive. The STING that helps fight infections in COPA patients, remain permanently active, which leads to chronic inflammation that damages the lungs, kidneys, and joints. In 2020, while studying STING’s role in the disease, researchers discovered a key variation: HAQ-STING. This version of STING, present in about one-third of the population, appeared to neutralize the harmful effects of the COPA mutation.

To confirm their theory, the scientists needed both affected and unaffected family members to participate in the testing. Letasha, Kristina and Betty immediately volunteered. The researchers then analyzed DNA samples from 26 COPA patients and their healthy relatives. They also conducted CT scans and blood tests to ensure that unaffected members did not have any hidden symptoms. When the findings were all clear, it was revealed that all the healthy individuals had HAQ-STING, while none of the COPA patients did. This was the first known case of a common gene variant completely protecting against a severe genetic disease.

Encouraged by this discovery, researchers tested HAQ-STING’s effects in a lab setting. They introduced it into diseased lung cells from COPA patients, and the cells returned to normal function.

Way Ahead

Shum believes HAQ-STING could lead to game-changing treatments, including:

  • Prenatal gene therapy for babies diagnosed with COPA Syndrome before birth
  • Aerosol delivery of HAQ-STING for adults, directly targeting the lungs

Before publishing their findings, Shum called Betty with the news—her own HAQ-STING gene had protected her from the disease. He also informed Letasha and Kristina, who were overwhelmed with relief and joy.

“We always believed Dr. Shum would get to the bottom of it,” said Letasha. “This discovery is going to change lives.”

National Medical Commission Orders Strict Safe Injection Practices In India: Here's Why It's Important

Updated Jun 5, 2026 | 09:28 PM IST

SummaryUnsafe injection practices continue in India, often under the guise of cost-saving. This has led to avoidable infections, lifelong treatment costs, and a loss of public trust in healthcare systems.
National Medical Commission Orders Strict Safe Injection Practices In India: Here's Why It's Important

The National Medical Commission (NMC) has issued an advisory mandating strict adherence to safe injection practices. The directive aims to curb preventable outbreaks of HIV, Hepatitis B (HBV), and Hepatitis C (HCV) caused by the unsafe reuse of syringes, needles, and other single-use medical devices.

Despite decades of evidence and repeated warnings from the World Health Organization (WHO), unsafe injection practices continue in India, often under the guise of cost-saving. This has led to avoidable infections, lifelong treatment costs, and a loss of public trust in healthcare systems.

What the NMC Advisory Says

The advisory mandates:

  • Single-use devices must never be reused:Reuse of syringes, dialyzers, or vials is a direct breach of patient safety.
  • Progressive adoption of safety-engineered auto-disable syringes: These devices prevent reuse and help protect healthcare workers from needle-stick injuries.
  • Strict enforcement of the Biomedical Waste Management Rules, 2016: Proper segregation and disposal of sharps is mandatory.
  • Mandatory training and audits: Healthcare workers must undergo regular competency assessments, and institutions must conduct strict monitoring.

Why Action Is Important

“India has the manufacturing capacity to supply safety-engineered syringes at scale. The barrier is not technology, it is willpower. Procurement administrators must prioritize patient safety over short-term cost-cutting,” said Rajiv Nath, Forum Coordinator of the Association of Indian Medical Device Industry.

“Single-use devices like syringes, dialyzers, and AV (Arteriovenous) fistula needles must not be reused. Unsafe injection practices are entirely preventable, and continuing them is indefensible,” he added.

The expert urged policymakers to act now because it is affecting

  • Public Health : Treating HIV, HBV, and HCV infections acquired through unsafe injections costs far more than investing in safe injection devices.

  • Global Credibility: As one of the world’s largest users of injectable medicines and vaccines, India’s leadership in safe injection, drug delivery, and blood management practices is critical to global health security.

  • Patient Trust: Every reused syringe erodes confidence in healthcare institutions and undermines national health programs.

Call to Action

The AiMeD stated that the NMC's advisory must be treated as a binding mandate, not a suggestion. Procurement administrators, hospital authorities, and policymakers should:

  • Enforce zero tolerance for device reuse across all healthcare facilities.
  • Allocate budgets for safety-engineered syringes, including auto-disable syringes and sharps injury-prevention devices, as a public health investment rather than a discretionary expense.
  • Establish accountability mechanisms through accreditation schemes, including audits, reporting of needle-stick injuries, and penalties for non-compliance.
  • Launch patient awareness campaigns to empower communities to demand safe injection practices.

"Unsafe injection practices are not a matter of affordability but of accountability. India has the capacity, technology, and cost-effectiveness evidence through Health Technology Assessment (HTA). What is needed now is decisive action to protect patients and healthcare workers alike," the AiMeD said.

Survival rates among patients with high-grade gliomas — one of the most aggressive forms of brain cancer — have improved by up to 50 per cent in India, according to leading oncologists ahead of World Brain Tumour Day 2026.

Doctors say a growing number of patients are now living significantly longer after diagnosis, with some surviving for more than a decade.

Advances Boost Survival Outcomes

Dr. Tejinder Kataria, Chairperson of Radiation Oncology at Medanta, said median survival for many high-grade glioma patients has increased from around 9–12 months to 14–18 months.

She noted that some centers are "reporting nearly 40 per cent two-year survival rates among patients with Grade III and Grade IV gliomas. In addition, about 5 per cent of patients in certain high-grade glioma groups are now surviving for more than 10 years".

Experts attribute these improvements to advances in molecular diagnostics, comprehensive genomic profiling, neuronavigation-assisted surgery, precision radiation therapy, and targeted treatments.

“Radiation oncology has evolved from open beams in the cobalt era to highly precise beam configurations using modern technologies. We are now able to deliver tumoricidal doses more accurately while also preserving quality of life,” Dr. Kataria said.

Personalized Treatment Changing Care

Dr. R. Ranga Rao, Chairman of Medical Oncology at Paras Health, said brain tumor treatment is no longer limited to surgery and radiation.

A deeper understanding of tumor biology is enabling doctors to tailor treatment according to the molecular profile of each patient’s cancer.

“Although high-grade gliomas remain challenging to treat, the combination of precision diagnostics, modern therapies, and multidisciplinary specialist care is helping more patients live longer and maintain a better quality of life than was possible even a few years ago,” Dr. Rao said.

He also highlighted the growing role of whole genomic sequencing, which helps clinicians understand a tumor’s genetic makeup and select more personalized treatment strategies that may improve survival.

Patients Should Not Lose Hope

Dr. Shyam Agarwal, Senior Consultant in Medical Oncology at Sir Ganga Ram Hospital, said many patients fear the worst when diagnosed with a brain tumor.

“People often feel that nothing can be done once they hear the word tumor in the brain. But brain tumors are of many different types — benign and malignant — and even malignant tumors vary widely in behavior,” he said.

According to Dr. Agarwal, modern treatment options, including surgery, radiation, targeted therapies, and newer drugs, can control many brain cancers for extended periods and may even offer a cure in selected cases.

He also stressed the importance of molecular testing and comprehensive genomic profiling to identify patients who may benefit from precision medicines.

Late Diagnosis Remains a Major Challenge

Despite advances in treatment, experts say delayed diagnosis remains a significant problem in India.

“The biggest blind spot in our country is that many patients reach specialists at a late stage. Symptoms may masquerade as routine headaches, hearing deficits, or visual disturbances. We need greater awareness,” Dr. Kataria said.

Dr. Agarwal added that delayed diagnosis is due to symptoms such as persistent headaches, hearing problems, or vision disturbances which are often mistaken for stress, migraine, or other common conditions, leading to late referrals.

What Is Glioma?

As per the Johns Hopkins Medicine, glioma is a common type of tumor originating in the brain. About 33 per cent of all brain tumors are gliomas, which originate n the glial cells that surround and support neurons in the brains, including astrocytes, oligodendrocytes and ependymal cells.

Gliomas are called intra-axial brain tumors because they grow within the substance of the brain and often mix with normal brain tissue. Symptoms include

  • Headaches
  • Seizures
  • Personality changes
  • Weakness in the arms, face or legs
  • Numbness
  • Problems with speech
  • Nausea and vomiting
  • Vision loss
  • Dizziness.

DAA Hip Replacement: A Modern Technique Helping Patients Recover Faster

Updated Jun 5, 2026 | 12:00 PM IST

SummaryHip pain and mobility issues are becoming increasingly common across all age groups today. Many people struggle with persistent pain while walking, sitting, climbing stairs, or even performing basic daily activities. In many cases, the discomfort gradually affects overall quality of life, limiting independence and confidence.
DAA Hip Replacement: A Modern Technique Helping Patients Recover Faster

With advancements in medical technology, hip replacement surgery has evolved significantly over the years. One of the most promising innovations in this field is the Direct Anterior Approach (DAA) Total Hip Replacement, a modern technique that offers patients a safer procedure, reduced pain, and faster recovery.

Unlike traditional hip replacement surgeries, the DAA technique allows surgeons to access the hip joint from the front through a small incision. The biggest advantage of this approach is that muscles are not cut during the surgery. Instead, they are gently separated, which helps minimize tissue damage and reduces post-operative pain considerably.

This muscle-sparing approach has transformed patient recovery experiences. Most patients are able to stand and walk on the same day of surgery, and hospital stays are generally shorter. Recovery is smoother, allowing individuals to return to their normal routine within three to four weeks in most cases.

The DAA technique is especially beneficial for patients suffering from chronic hip pain, restricted movement, or severe joint damage. Common conditions that may require hip replacement include osteoarthritis, avascular necrosis (AVN), rheumatoid arthritis, old hip fractures, and long-standing degenerative joint conditions. When medications, physiotherapy, and injections fail to provide lasting relief, hip replacement surgery can significantly improve mobility and quality of life.

Compared to conventional hip replacement procedures, DAA offers several advantages. The surgery involves a smaller incision, less blood loss, minimal muscle damage, and lower post-surgical discomfort. Patients are able to regain movement faster and often experience greater confidence during rehabilitation.

One of the most common concerns among patients is the fear of severe pain after surgery. However, with modern pain management techniques and advanced surgical methods, discomfort after DAA hip replacement is usually minimal and manageable. Patients today recover much more comfortably than they did in the past.

Another important factor is the durability of modern implants. Advances in implant technology have significantly improved their lifespan, with many implants lasting more than 25 years. Maintaining a healthy body weight, staying physically active, and following medical advice can further improve the longevity and effectiveness of the implant.

After successful recovery, patients are generally able to resume a normal and active lifestyle. They can return to work, perform household activities independently, and participate in light exercises such as yoga, swimming, and stationary cycling. The primary goal of hip replacement surgery is not just pain relief, but restoring confidence, mobility, and independence.

Preparation before surgery also plays an important role in achieving better outcomes. Patients are advised to maintain controlled blood sugar levels, blood pressure, and overall heart health. Informing doctors about ongoing medications, performing basic physiotherapy exercises before surgery, and preparing a comfortable recovery environment at home can contribute to a smoother rehabilitation process.

Hip pain should never be ignored, especially when it begins affecting daily life and mobility. Timely treatment and the right surgical approach can make a remarkable difference. The Direct Anterior Approach has made hip replacement surgery simpler, safer, and more patient-friendly, helping individuals return to an active and pain-free life much faster than before.
