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

People think of menopause as just hot flashes and irregular periods, but menopause is more than that.
Perimenopause and menopause can bring a host of emotional and cognitive shifts for many women, including mood swings, anxiety, easily irritated, trouble sleeping, or having what some refer to as “brain fog.”
Perimenopause is the period leading up to menopause that can last anywhere from two to eight years. This is when hormonal changes take place, especially a drop in estrogen.
These hormonal changes also impact neurotransmitters like serotonin and dopamine that are essential for mood, memory, sleep and emotional wellness.
Consequently, a woman can suffer from forgetfulness, lack of concentration, mental tiredness, low energy levels, dry skin, loss of libido and less productivity.

Brain fog can be a frustrating and overwhelming experience during menopause, particularly if a woman is juggling her career, family, ageing parents and personal obligations.
Many women suffer from anxiety symptoms, even if they have no mental health background. Hormonal changes, poor sleep and stress can exacerbate these symptoms.
But not all symptoms are due to the menopause or "normal ageing". Thyroid disorders, vitamin deficiencies, depression and other medical problems can have similar symptoms.
Therefore, if symptoms start to impact life, work, relationships or emotional wellbeing, it is important to seek medical advice and have a proper health check-up.
Management is often comprehensive, and may involve lifestyle modifications. Regular exercise, balanced nutrition, stress management and healthy sleep patterns.
In a few instances, you may additionally be suggested to take Menopausal Hormone Therapy (MHT). As more research is done and preparations of lower doses and greater safety, earlier misconceptions about hormone therapy are gradually decreasing.
Medically, women can make a difference in their quality of lives and manage menopause with greater physical, mental and emotional wellness with early recognition and timely intervention.

Everyone knows that using sunscreen is one of the most important steps for protecting the skin from harmful sun rays, but dermatologists explain that it isn't the only thing you should do to keep your skin healthy. Other daily routines are also important for minimizing sun damage and maintaining healthy skin over time.
Skin is a protective barrier for the body but constant exposure to the sun, pollution, heat and unhealthy lifestyle habits can make this barrier vulnerable.
Once the skin barrier is damaged, the skin is more susceptible to tanning, pigmentation, dryness, sun ageing and other sun damage.
Using a moisturiser every day is a very simple, yet effective habit. A good moisturiser is one that doesn't contain any scents and will support the barrier function of the skin, thereby preventing unwanted water loss from the skin.
Wet and plump skin is resistant to the environment and sun's rays.

Antioxidants are also a best practice for dermatologists. Antioxidants prevent the damage to skin cells by free radicals created by UV exposure, pollution etc.
This protection can help minimize issues like hyperpigmentation, uneven skin tone and premature ageing. Consuming foods that contain antioxidants (such as fruits, vegetables and nuts) can help keep skin healthy on the inside.
Next, hydration is crucial. It's important to keep drinking enough water all day long to keep the skin supple and to allow the skin to repair itself. Moisture also contributes to skin's healing from environmental stress.
Sun protection is also of great importance. Wearing hats or caps, using umbrellas, and wearing clothing that protects against the sun's rays can minimize direct exposure to the sun.
All these are simple actions that serve as a physical barrier and prevent sunburn and long term damage to the skin, particularly between 10 a.m. and 4 p.m. These simple steps provide a physical barrier and reduce the risk of sunburn and chronic skin damage, particularly in the peak hours of 10 a.m. to 4 p.m.

Another focus has been on the connection between gut health and healthy skin, as experts recognize how crucial the role of the gut is in maintaining healthy skin.
Probiotics can potentially improve the gut-skin axis and aid in the healing process and alleviate inflammation in the body. The better the gut environment, the better the skin will be able to recover and the less the exposure to the sun will age the skin.
Some people can use collagen supplements as an added benefit. Collagen is involved in supporting the dermis, the skin's structural component. Keeping collagen high can help promote skin repair and healing mechanisms.
Doctors say while sunscreen is important, long-term skin protection can be achieved through a variety of healthy habits, proper nutrition, hydration and physical sun protection measures, which must be followed daily.

We tend to think of our eyes as easy – they just "see", and we go about our day. But the fact is, your eyes are adapting a lot, focusing and straining all the time, far more than you realize. Many of these moments are utterly unremarkable, but they build up gradually into a tiredness, a dryness and a long-term strain.
We see many people who are shocked to find out how hard their eyes had been working long before any symptoms appeared. Here are six common situations that deserve a whole lot more attention – and care – from your eyes.
Having a quick glance at notifications before even leaving bed requires your eyes to adjust to a small, bright screen in the dark. This quick change puts a load on the eye muscles and can make them tire before your day has really started.
Working, studying, and hopping from meeting to meeting: extended hours in front of the screen drastically lower your usual blink rate. Less blinking equals less lubrication, which is why so many people are dry, irritated and have blurry vision by the afternoon.
Night driving is one of the most challenging visual jobs humans undertake, given low light, incoming headlights and the need to constantly change focus between the road, mirrors and dashboard. Your eyes are working tirelessly to shift between bright and dim situations in fractions of a second.

Poorly lit restaurant menus, pharmaceutical labels, or the small text on a contract all demand that you focus hard at close range, frequently in less-than-ideal illumination. As we get older, this type of near-focus strain is very common since our natural ability to focus declines.
Glancing from your laptop to your phone to a television and back again, it makes your eyes refocus at multiple distances. It is easier, but this continual flipping is more tiring than looking at one screen for the same period of time.
Your eyes work hard to adjust while you move from a dim room into harsh daylight — or vice versa. Over time, repeated exposure to glare without the correct protection (such as sunglasses) can add unneeded strain.
None of these moments feel dramatic on their own, but together, they represent a significant daily workload for your eyes. The good news is that habits such as the 20-20-20 rule, correct lighting, regular blinking and eye check-ups can go a long way in reducing this concealed tension. We believe that awareness is the beginning of healthy eyesight.
If you are suffering frequent eye strain, dryness or fuzzy vision, it may be time to schedule a full eye exam. Your eyes work harder than you realize – let’s give them the attention they deserve.
