The global challenge of HIV/AIDS remains one of the most pressing public health issues today. According to the latest data from UNAIDS, around 38.4 million people worldwide are living with HIV/AIDS, underlining the need for not only medical intervention but also comprehensive awareness, education, and social change. Despite the significant strides made in treatment and prevention, the confusion surrounding the relationship between HIV and AIDS still persists.

Young people have become influential advocates in the fight against HIV/AIDS. Research from UNICEF shows that youth-led initiatives can lower HIV transmission rates by as much as 45% in targeted communities. These young activists utilize digital platforms and peer-to-peer education to dispel myths, promote safe practices, and foster supportive environments for those affected by HIV/AIDS.

Dr Gowri Kulkarni, an expert in Internal Medicine, explains that while the terms HIV and AIDS are often used interchangeably, they are distinctly different. "HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system, whereas AIDS (Acquired Immunodeficiency Syndrome) is a condition that occurs when HIV severely damages the immune system," she clarifies. To understand the implications of these differences, it's important to explore the fundamental distinctions between the two.

1. HIV is a Virus; AIDS is a Syndrome

HIV is the virus responsible for attacking the body’s immune system, specifically targeting CD4 cells, which are crucial for the body’s defense against infections. As HIV progresses, it destroys these cells, weakening the immune system over time. If left untreated, this continuous damage can lead to AIDS.

AIDS, on the other hand, is a syndrome, not a virus. Dr Kulkarni further elaborates that AIDS is a collection of symptoms and illnesses that emerge when the immune system is severely compromised due to prolonged HIV infection. It represents the most advanced stage of HIV, and is characterized by very low CD4 counts or the onset of opportunistic infections like tuberculosis, pneumonia, or certain cancers.

2. Not Everyone with HIV Develops AIDS

A key distinction to remember is that not everyone with HIV will progress to AIDS. Thanks to advancements in medicine, particularly antiretroviral therapy (ART), individuals living with HIV can manage the virus and maintain a healthy immune system for many years, or even decades, without ever developing AIDS. ART works by suppressing the virus to undetectable levels, effectively preventing the damage HIV would otherwise cause to the immune system.

Without treatment, however, HIV progresses through three stages:

- Acute HIV Infection: This stage occurs shortly after transmission and may include symptoms like fever, fatigue, and swollen lymph nodes.

- Chronic HIV Infection: Often asymptomatic or mildly symptomatic, the virus continues to damage the immune system but at a slower rate.

- AIDS: This is the final stage, marked by severe immune damage and the presence of infections that take advantage of the compromised immune defenses.

3. HIV is Transmissible; AIDS is Not

Another key distinction between HIV and AIDS is the way in which they are transmitted. HIV is highly contagious and can be transmitted through the exchange of bodily fluids such as blood, semen, vaginal fluids, and breast milk. It is primarily spread through unprotected sexual contact, sharing needles, or from mother to child during childbirth or breastfeeding.

AIDS, however, is not transmissible. It is not a disease that can be passed from one person to another. Rather, AIDS is the result of untreated, advanced HIV infection and is a direct consequence of the virus’s damage to the immune system.

4. Diagnosis Methods Differ

HIV and AIDS are diagnosed through different methods. HIV is diagnosed through blood tests or oral swabs that detect the presence of the virus or antibodies produced by the immune system in response to the virus. Early detection of HIV is crucial, as it allows for timely intervention and treatment, which can prevent the virus from progressing to AIDS.

AIDS, on the other hand, is diagnosed using more specific criteria. Dr Kulkarni notes that the diagnosis of AIDS is made when the individual’s CD4 cell count falls below 200 cells/mm³, or when opportunistic infections or certain cancers (such as Kaposi's sarcoma or lymphoma) are detected. Diagnosing AIDS involves a more thorough assessment of the individual’s immune function and overall health, as opposed to just the detection of HIV.

5. Treatment Goals Are Different

The treatment goals for HIV and AIDS differ significantly, although both involve antiretroviral therapy (ART). For HIV, the primary treatment goal is to suppress the virus to undetectable levels, thus maintaining a strong immune system and preventing further transmission of the virus. People living with HIV can often live long, healthy lives if they adhere to ART.

For individuals diagnosed with AIDS, the treatment plan becomes more complex. While ART remains an essential part of managing the virus, treatment for AIDS also focuses on addressing the opportunistic infections and secondary health complications associated with severe immune suppression. The goal of treatment for AIDS is not only to manage the HIV virus but also to improve the quality of life and extend survival by treating these secondary health issues.

Role of Community Engagement in Combatting HIV/AIDS

While the medical community has made great strides in managing HIV, the battle to curb its transmission is also a social and cultural issue. Dr Daman Ahuja, a public health expert, highlights that HIV/AIDS awareness and education are vital to reducing transmission rates and supporting those affected by the virus. "Young people, especially, have become key advocates in the fight against HIV/AIDS," says Dr Ahuja. "Research from UNICEF shows that youth-led initiatives can lower HIV transmission rates by as much as 45% in targeted communities."

Additionally, grassroots activism plays a significant role in raising awareness and addressing stigma. As the World Health Organization reports, community-based interventions have been proven to increase HIV testing rates and improve treatment adherence, which are crucial in the fight against the pandemic.

The ultimate goal of organizations like UNAIDS is to eliminate the HIV/AIDS pandemic by 2030. Achieving this requires global collaboration, from medical treatment advancements to public health strategies, education, and advocacy. Dr Kulkarni’s insight underscores the importance of early detection, treatment adherence, and community support in the fight against HIV/AIDS.

Persistent back pain in young adults is often dismissed as poor posture, long hours at a desk, or muscle strain. But doctors are warning that in some cases, it could be a sign of ankylosing spondylitis — a chronic inflammatory autoimmune disease that affects the spine and can silently progress for years before diagnosis.

In India, 16.5 lakh people suffer from the condition, with an average diagnostic gap of nearly seven years from the time symptoms first appear. During that window, the disease continues to silently progress, and the burden is far from small.

“Ankylosing Spondylitis is one of the most underdiagnosed conditions we encounter in clinical practice, and the consequences of that delay are real,” Dr. Arvind Mehra, Senior Director and HOD - Orthopaedics at Paras Health Gurugram, told HealthandMe.

Moreover, “It takes several years of pain and stiffness before people seek treatment, and by then, the diagnosis comes too late, and there has already been damage to the spine,” added Dr. Ashish Tomar, Director - Orthopaedics & Minimally Invasive Spine Surgery at Sarvodaya Hospital, Faridabad.

What Is Ankylosing Spondylitis?

Ankylosing spondylitis, also known as axial spondyloarthritis, is a type of arthritis that primarily targets the spine but can also affect other joints. The term “ankylosing” means stiff or rigid, “spondyl” refers to the spine, and “itis” indicates inflammation.

The inflammatory disease causes some of the bones in the spine to fuse over time. This fusing not only makes the spine less flexible but can also cause issues while breathing.

Ankylosing spondylitis leads to inflammation in the spine and large joints, causing stiffness and pain. It can also impact the joint between the spine and the hipbone, potentially resulting in additional symptoms such as digestive issues, rashes, and weight loss.

Not Your Typical Back Pain

What makes ankylosing spondylitis difficult to spot is that it often feels like ordinary back pain — but there are warning signs that set it apart.

According to experts, ankylosing spondylitis-related pain typically:

• Causes maximum stiffness early in the morning
• Gets worse after long periods of rest
• Improves with physical activity or exercise
• Persists for months rather than days or weeks
• Often begins in young adults, especially in their 20s and 30s

This pattern is very different from mechanical back pain, which usually worsens with movement and improves with rest.

Pain Beyond The Spine

Dr. Tomar told HealthandMe that ankylosing spondylitis is not simply a musculoskeletal problem — it is an autoimmune disease, where the body’s immune system mistakenly attacks healthy tissues, particularly around the spine and joints.

“Ankylosing spondylitis is not just another musculoskeletal disease. It requires the attention given to autoimmune disorders because it may affect the chest, hips, shoulders, and even the eyes, while also causing severe posture problems in advanced stages,” he said.

Beyond the spine, the disease may affect:

• Chest joints
• Hip joints
• Shoulders
• Eyes
• Posture, causing severe problems in the advanced stages

Who Is At Most Risk? How To Treat?

Young adults, typically in their twenties, are more likely to experience this condition because people often overlook its existence or mistakenly identify it as something else.

The combination of early diagnosis, structured physiotherapy, and suitable medications allows for effective disease progression control.

“When a young adult presents with inflammatory back pain, especially in the gluteal area, that persists beyond three months, the reflex should not be to prescribe a painkiller and wait. It should be investigated further. That shift in approach can make an extraordinary difference to someone’s long-term quality of life,” Dr. Tomar said.

Common treatments for ankylosing spondylitis include:

• Regular physical activity can reduce stiffness and prevent worsening of ankylosing spondylitis
• Over-the-counter painkillers for pain and inflammation
• Biologic DMARDs to reduce inflammation and pain, potentially halting disease progression.
• Corticosteroids are prescription anti-inflammatory medications
• Surgery is rarely suggested for severe symptoms unresponsive to other treatments.

When women are in their 40s, their bodies start to change a lot because of the hormones. This is mainly because the estrogen and progesterone levels in the body start to go down. This time is called Perimenopause.

It is when women start to move towards menopause. It can bring a lot of emotional changes. Some of these changes are normal.

Why Do Hormonal Changes Happen After 40?

After 40, women's bodies start to produce estrogen. This means they can have an imbalance.

Women's bodies need hormones like estrogen and progesterone to have periods, strong bones, a good mood, and to stay at a healthy weight. When these hormone levels change, it affects parts of the body. This change can take a year before it stops at menopause.

Common hormonal changes women experience

• Irregular periods

• Hot flashes and night sweats

• Mood swings and anxiety

• Weight gain and slower metabolism

• Sleep disturbances

• Skin and hair changes

Symptoms That Should NOT Be Ignored

While some changes are normal, some symptoms need a doctor's help:

• Heavy or prolonged bleeding

• Persistent fatigue

• Severe mood changes

• Sudden weight gain

• Bone pain or weakness

When women are over 40 and their hormones change, they are more likely to have:

• Heart disease
• Osteoporosis
• Thyroid disorders
• Metabolic issues

Estrogen helps keep the heart and bones healthy, so when its levels go down, women are more likely to have these health problems."

How Can Women Manage These Changes?

• Eat a balanced diet

• Exercise regularly

• Manage stress

• Have regular health check-ups

• Sleep well

Women should talk about these changes openly. If they know what is happening and see a doctor early, they can make this time easier.

Hormonal changes after 40 are a part of getting older, but women should not ignore them. Especially if the symptoms are very bad or happen all the time.

If women understand what is happening in their bodies and see a doctor when they need to, they can be healthier and more confident. If women take care of themselves now, they can have a life in the years to come.

The US Food and Drug Administration (FDA) has approved tradipitant to be sold under the brand name Nereus, for the prevention of vomiting induced by motion in adults — a first in the last four decades.

Motion sickness affects an estimated 65 to 78 million Americans—roughly 25 to 30 percent of adults—during everyday travel by car, plane, or boat. For decades, patients have had no meaningful new treatment options.

Tradipitant is an oral neurokinin-1 (NK-1) receptor antagonist that prevents motion-induced vomiting in adults.

It is an oral capsule, often taken 60 minutes before travel to block signals causing nausea.

The drug by Vanda Pharmaceuticals is now commercially available across the US.

"Today marks an important milestone for the tens of millions of Americans who experience motion sickness symptoms during common travel," said Mihael H. Polymeropoulos, M.D, President, CEO, and Chairman of Vanda, in a statement.

How Tradipitant Prevents Motion Sickness?

Motion sickness occurs when the brain receives conflicting signals from the eyes, inner ear, and body while in motion. This sensory mismatch is believed to trigger the release of substance P, which activates NK-1 receptors in the central nervous system and ultimately leads to nausea and vomiting.

Tradipitant works by blocking these receptors, interrupting the vomiting pathway.

"NEREUS is a selective, high-affinity antagonist of human substance P/neurokinin-1 (NK-1) receptors that can block the vomiting center of the brain,” Polymeropoulos said.

Tradipitant was approved by the FDA, following two pivotal Phase 3 clinical trials—Motion Syros and Motion Serifos—conducted under real-world conditions on the open sea.

Both studies demonstrated that tradipitant significantly prevents vomiting compared to placebo, confirming the drug's effectiveness in actual sea travel conditions. It is the first new prescription option for people with a history of motion sickness in over 40 years.

It employs a novel mechanism as a selective, high-affinity antagonist of human substance P/NK-1 receptors. It offers simple dosing with just one or two capsules a day taken approximately an hour before travel.

Is Tradipitant Safe? Are There Any Side-Effects?

According to Vanda Pharmaceuticals, tradipitant may impair abilities required for driving a motor vehicle or operating heavy machinery.

Combining tradipitant with sedatives or medications that increase the drug's levels may increase this effect. If use together cannot be avoided, your doctor may warn against driving or operating heavy machinery.

The most common side effects associated with tradipitant include drowsiness, headache, and fatigue.

Moreover, strong CYP3A4 inhibitors may increase NEREUS™ levels and the risk of side effects, the company said.

There are limited data on tradipitant's use in pregnant women and children.

Tradipitant is also not recommended in patients with liver problems or severe kidney problems.
