World Aids Day
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.
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.
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.
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.
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.
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.
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.

For many young and middle- aged adults, headaches or brief dizzy spells often feel routine — attributed to long work hours, stress, or poor sleep. Occasional blackouts or “spacing out” episodes may be brushed aside as fatigue or skipped meals.
What makes these symptoms particularly dangerous is that they are often mistaken for burnout, stress, migraines, or exhaustion — especially among younger working professionals. While most headaches are harmless, persistent neurological symptoms that disrupt daily life should never be ignored.
But there are neurological symptoms you should never ignore: sudden seizures, memory loss after brief collapse, repeated headaches, unexplained weakness, or changes in personality. These can sometimes point to an underlying brain disorder — and, in rare cases, to Glioblastoma, one of the most aggressive forms of brain cancer.
Glioblastoma (GBM) is one of the most aggressive and fast-growing forms of brain cancer in adults. It develops in the supportive tissue of the brain and can quickly affect memory, speech, movement, personality, and other neurological functions. Because the tumour tends to spread into nearby healthy brain tissue, complete surgical removal is often difficult, making timely diagnosis and treatment extremely important. While brain tumours are often associated with older adults, specialists are increasingly seeing younger individuals dismiss early warning signs as work-related fatigue, lack of sleep, stress, or lifestyle burnout. Delayed recognition can sometimes postpone critical medical intervention. In India, there are around 23,000 glioblastoma cases per day, considered higher incidence rates along with North America, Australia, Northern and Eastern Europe. Seizures and persistent headaches are often among the earliest symptoms that prompt medical investigation.
Recently, a 34-year-old woman presented to Apollo Hospitals, Bannerghatta with seizures and memory loss. Her first seizure occurred one morning at home — she collapsed briefly, with twisting of arms and legs, and woke with total memory loss of the episode. Like many young professionals struggling between work and personal commitments, she first considered the cause to be work-induced stress. The family did not suspect that these seemingly routine headaches and blackouts could indicate a serious neurological condition. Before that, she had minor headaches — the kind most people ignore. An MRI scan revealed brain swelling, and anti-seizure medication was prescribed. A second opinion at month’s end showed swelling reduction.
The turning point came in late, during a road trip, when she suffered three seizures in two hours. A burr hole biopsy of a right frontal lesion suggested a diffuse low-grade glioma. Subsequent evaluations at Apollo Hospitals upgraded the diagnosis to bifrontal Glioblastoma — a clinically challenging case due to its location. This is a clinically unusual case because most of the time, GBM is diagnosed with MRI with contrast, MR spectroscopy, and biopsy to confirm the type and grade of tumor. In this patient’s case, imaging revealed widespread bifrontal involvement — making conventional surgery high risk. Her care team opted for a non-surgical precision radiotherapy approach. She had 25 high precision image guided radiotherapy (IGRT) sessions using RapidArc technology. This was followed by two CyberKnife boost sessions to high-risk tumour areas - a plan to boost treatment precisely where it was most needed. All sessions went smoothly, with no major side effects. Since October 2024, she has been undergoing her cycle of monthly chemotherapy treatment alongside her regular scanning.Happily, she was also able to slowly get back to work, engage in recreational activities, and gain a semblance of normal life despite the ongoing cancer treatment.
Signs that point to headaches along with seizures, vomiting, blurred vision, confusion, personality changes, weakness, or an increasing frequency of symptoms should be evaluated medically without delay. Even one seizure is not an issue to ignore.
Some symptoms you must mention to your doctor will be:
It may help you diagnose your problems effectively if you see a neurologist, conduct MRI brain imaging and have consultations from an early stage. While some headaches or seizures do not necessarily mean having a tumor in the brain, regular occurrence of such symptoms with no reason is likely to be examined by an expert. However, although a proper healthy lifestyle may help your brain remain healthy, it will be ineffective for illnesses like GBM.

Glomerular Diseases affect the glomeruli, which are very small filtering units in the human kidney, and when they get damaged due to disorders, the filters leak blood and vital proteins into the urine and fail to remove waste efficiently. Eventually, these problems can lead to chronic kidney disease or kidney failure. As per its treatment, medications are used to slow kidney damage, manage blood pressure, and reduce protein leakage.
Notably, a new study has revealed hope in this condition by finding that a well-known drug can be very effective in slowing damage if the patient has Glomerular Diseases, and that common drug is Finerenone, which is often prescribed for heart and kidney diseases associated with type 2 diabetes.
The trial was participated in by 903 participants with glomerular diseases. The drug finerenone was given to them. The results show that compared with placebo, it slowed kidney damage, reduced albuminuria, and lowered the risk of kidney failure or sustained loss of kidney function.
Thus, the study clearly indicates that the drug called finerenone may play an important role in protecting kidney function in patients with glomerular diseases.
The research was conducted through subgroup analysis of a phase 3, randomized, double-blind, placebo-controlled trial conducted across 24 countries and regions, focusing on participants with an investigator-reported glomerular disease.
The study was conducted on a large scale, having conducted the research for months in 24 countries and regions. The trial also took care of other important details and implemented all required paperwork, thus securing approvals by regulatory authorities along with ethics committees in every center. Other than that, the participants were required to submit written informed consent. Moreover, an independent data monitoring committee performed safety monitoring throughout the tests.
Dietary habits can contribute to kidney strain, particularly when busy schedules encourage reliance on convenient foods that are often high in sodium and low in nutritional value.
Hydration habits are additional concerns among office workers. Many professionals rely heavily on coffee, energy drinks, or sugary beverages during long workdays, often replacing plain water as the main source of fluid intake.
Protecting kidney health often begins with small lifestyle changes. Reducing processed food consumption, limiting excessive salt intake, staying adequately hydrated, and maintaining regular sleep schedules can all support kidney function.
Taking short movement breaks during long work hours and managing stress through regular physical activity or relaxation techniques may also help reduce the long-term strain that modern work routines place on the body.

Convenience foods have become the defining feature of urbanization. From ready-to-eat breakfasts to microwavable dinners and takeaway lunches, packaged food fits into all our lives.
But behind this convenience, what lies underneath are the tiny plastic particles, also referred to as microplastics, which are accentuating health concerns across the globe. Unknowingly, these microplastics are seeping through the plastic cutlery, food packaging, etc., potentially into our bodies. Plastics have been widely used for ages due to their higher affordability, durability, and extensive applications in various industries.
As per a recent literature quoted by Zhang et al. 2025, only about 20% of the plastic waste produced is recycled, whereas the rest is either abandoned in landfills or dispersed into the environment. Microplastics are the new emerging pollutant category in the modern era, raising prominent concerns in both health & environmental contexts. As per scientific literature, microplastics are plastic fragments with a diameter of less than 5mm.
Plastic food packaging dominates the global food system, since it can be designed in any form (container, wrapper, pouch, etc) while keeping food fresh for longer periods.
Microplastics are released from food packaging(s), especially when they are exposed to prolonged heat, abrasive forces, and undue environmental stresses. Heating and/or reheating food in plastic containers or choosing to decant packaged food commodities in plastic containers and maintaining them under unfavorable circumstances can all increase the likelihood of microplastic release.
Bottled water has also proven to release thousands of microplastic particles into the water they contain when exposed to sunlight/ heat. We never give a thought to such bottles being sold by the roadside vendors, wherein these plastic bottles are hung for indefinite days on that kiosk.
Those bottles are in constant light exposure all day without even pondering about the ill effects it may cause to the consumers. Similarly, single-use tea bags have also been shown to release billions of microplastics when steeped in hot water. These findings highlight a troubling paradox that products marketed for convenience and safety may be introducing new risks that consumers never thought about.
The health implications of ingesting microplastics remain an active area of research, but early findings are enough to raise concerns. Studies have demonstrated microplastics in human blood, lungs, and even placental tissue. This suggests that upon ingestion, these particles may not simply pass through the body. Instead, they would accumulate in tissues or interact with biological systems in ways that are not yet fully explored.
One of the major health implications pertaining to microplastic ingestion is inflammation. These particles can trigger irritation in tissues, eventually impacting the immune responses.
Plastics often contain additives in the form of plasticizers, etc., which may disrupt hormone function and impair the normal cellular function.
Infants and children are more often vulnerable as their food is also packed in plastic packaging or containers (like plastic sippers, feeding bottles, baby food pouches, etc.), raising long-term exposure risk during critical stages of growth.
The issues relating to plastic usage also reflect a broader tension in the modern era, where convenience seems to intersect with health! For people or families juggling work and financial burdens, avoiding packaged foods mostly sounds unrealistic.
Still, some small and consistent actions can help us reduce the exposure to microplastics, like opting for glass or paper packaging wherever possible. Avoiding heating food in plastic containers or opting for biodegradable packaging options could prove to be beneficial in the future. Though microplastics are invisible to our naked eyes, what we do next to curb them would help us shape a healthy future.
