With the US pausing its funds in the healthcare sector, along with UNAIDS, a global threat for HIV cases has risen. It has led to panic, fear, and confusion in many African countries who are the hardest hit by AIDs. In fact, official data states that this move could lead to a 6 times jump in HIV cases. While HIV and AIDS are being discussed all over the news now, not many know the difference between the two.

What is HIV? What is AIDS?

Human immunodeficiency virus or HIV is a diseases that weakens a person's immune system by attacking CD4 cells which help the body fight off infection.

Whereas AIDS, which stands for acquired immunodeficiency syndrome happens when the HIV advances.

How Is It Spread?

HIV is primarily spread by:

• Having multiple sex partners or the presence of other sexually transmitted diseases which can increase the risk of infection during sex. Unprotected oral sex can also increase for HIV, though it is a much lower risk than anal or vaginal sex
• Sharing needles, syringes, rinse water
• Being born to an infected mother

The Origin

The first known case of HIV-1 infection in human was detected in 1959, from a blood sample of a man in Kinshasa, Democratic Republic of Congo. However, the source of his infection is not known. The genetic analysis of the blood sample revealed that HIV-1 may have stemmed from a single virus in late 1940s or early 1950s.

In the US, this virus existed from mid 1970s. Between 1979-81 rare types of pneumonia, cancer and other illnesses were reported to doctors in Los Angeles and New York, and a number of the patients were men who had sex with other men. The conditions reported in those patients were not found in a person with healthy immune system. In 1982, healthcare officials began to use the term acquired immunodeficiency syndrome, that is how it was named AIDS. The DC Health website mentions that this term was used to describe the occurrences of opportunistic infections. It was in 1983 that the scientists finally discovered the virus that caused AIDS. The virus was first named HTLV-III/LAV (human T-cell lymphotropic virus-type III/lymphadenopathy-associated virus) by an international scientific committee. This name was later changed to HIV (human immunodeficiency virus).

Countries With Highest HIV Rates

As per the World Population Review, the top 10 countries with the highest HIV rates as of 2023 are:

• Eswatini at 27.5%
• Lesotho at 20.5%
• Botswania at 19.7%
• South Africa at 16.6%
• Mozambique at 11.8%
• Zimbabwe at 11.7%
• Namibia at 11.5%
• Zambia 11%
• Malawi at 7.5%
• Uganda at 5.6%

Then there are the countries with the most number of people living with HIV as per 2023:

• South Africa: 7,700,000
• India: 2,500,000
• Mozambique: 2,400,000
• Nigeria: 2,000,000
• Tanzania: 1,700,000
• Uganda: 1,500,000
• Kenya: 1,400,000
• Zimbabwe: 1,300,000
• Zambia: 1,300,000
• Brazil: 1,000,000

Three Stages of HIV

HIV progresses and becomes AIDS in three stages:

Acute HIV infection: It has flu-like symptoms in the host and starts to destroy body's CD4 T lymphocyte cells.

Chronic HIV: While the HIV levels are lower, it is still persistent. Infected individuals may have no symptoms and the risk of transmission to others is also diminished to a certain level. The World Population Review mentions: Patients on treatment plans may have virus levels so low as to be undetectable, making the risk of transmission nearly zero, and live at this stage for decades.

Acquired Immunodeficiency Syndrome: This is the third stage of HIV infection, if left untreated, it can progress to AIDS, where your body is no longer to fight off any infections.

You may have heard cancer survivor stories and how they inspired people through their journey. They fought and are now living proof of what ‘coming out stronger’ looks like.

Linda Burchett, 75 years old, this year celebrates the 10 years of being cancer free, explaining how she is the ‘encourager’, who 'encourages’ people to never give up on their hopes. For her, the cancer diagnosis started off as a mere indigestion-like symptom. " I thought I was having indigestion, and the pain had started radiating through to my back. I asked my husband to google heart attacks in women because I thought maybe that was what was happening." Upon their arrival at the doctors, she was diagnosed with pancreatitis. Having prior experience with this condition through her daughter, Linda was familiar with the diagnostic process, which included an endoscopic ultrasound.

Unexpected Cancer Revelation

During the ultrasound, the doctor expressed a low expectation of finding anything significant, a sentiment Linda shared. However, within 24 hours, she received the unexpected news that she had pancreatic cancer. Despite this serious diagnosis, Linda, who describes herself as having a naturally calm and peaceful disposition, calmly anticipated surgery as the next step, believing the tumor would be removed and life would continue normally.

But things didn't go as planned for Linda. “It (the cancer mass) was going to be removed, and life would go on. Well, that changed. About four or five days before the surgery the surgeon said your mesenteric artery is 80% compromised so the surgery is not possible.” Because of this, the doctors couldn't do the surgery. The conversation quickly changed, and the surgeon asked Linda where she wanted to have her chemotherapy treatment. Linda said that the chemotherapy made her feel very sick all the time, which was a difficult experience for her to go through on a daily basis.

New Hopes For Recovery And Treatments

Even though the chemotherapy was hard, Linda had something wonderful to look forward to. About a month after she was diagnosed with cancer, she found out that she was going to have a grandchild.

This news gave her a strong reason to keep fighting and to want to live so she could spend time with her new grandchild. The chemotherapy actually helped shrink the tumors enough that the doctors could try the Whipple surgery after all, but they needed a vascular surgeon to be there during the operation to help.

What Is Whipple Surgery?

According to the Whipple Procedure (Pancreaticoduodenectomy, the Whipple surgery, also called pancreaticoduodenectomy, is the main operation doctors use to take out tumors in the pancreas. If doctors can remove the tumor with surgery, it gives the best chance to control all kinds of pancreatic cancer for a long time. The Whipple surgery is a big and complicated operation because it involves taking out and putting back together a large part of the digestive system.

The recovery following the Whipple surgery was far from straightforward. What was anticipated to be four weeks of daily radiation and chemotherapy was complicated by an infected port, dangerously low blood pressure, high temperatures, and low white blood cell counts. This extended her recovery period to approximately three months. During this intense time, Linda, a lifelong Christian, found herself drawing immense strength and comfort from her deepened connection with God.

Milestone And New Hope For Life

Linda had her first scan that showed no signs of cancer on October 15th. The very next day, October 16th, her grandson was born. It was the happiest week of her life – being cancer-free and becoming a grandmother.

After she recovered, Linda would go back to the place where she had her treatments to encourage other people who were still going through it. She felt that because she had so many problems during her own treatment, she could really understand what they were experiencing. She said that no one there had gone through anything she hadn't also been through.

“This is not a journey for you to take by yourself.” she encouraged people to reach out to their loved ones and not to lose hope. “Because of being able to bless other people that's what I really want to accomplish to make connections with other people going through this journey and I'm just enjoying and celebrating every day.”

Symptoms of Pancreatic Cancer

The American Cancer Society explains that pancreatic cancer may not cause signs and symptoms, by the time you do notice something different, it could have grown quite large and spread outside the pancreas. Here are some symptoms of it you should know.

• Fatigue or abnormal weakness
• Jaundice (yellowing of skin and eyes)
• Dark urine
• Light-colored or greasy stools
• Itchy skin
• Weight loss and poor appetite
• Belly or back pain
• Nausea and vomiting
• Gallbladder or liver enlargement
• Blood clots
• New-onset or poorly controlled diabetes

More than 200 million smartwatches were sold worldwide alone in 2023, with millions of users counting on these wrist-worn devices not only for convenience—but for lifesaving alerts. As wearable health technology advances, smartwatches have become the daily companion in monitoring heart rate, blood oxygen, and even irregular rhythms. But since cardiovascular disease is still the top killer globally, a pressing question arises: Can your smartwatch really sense and even prevent a heart attack before it's too late?

While these gadgets promise to track pivotal indicators such as atrial fibrillation and fluctuations in blood pressure, their potential to foretell acute cardiac events continues to be an area of research. As technology brands compete to make medical features intelligent, the reality falls where innovation, clinical science, and what your smartwatch can practically do converge.

Smartwatches no longer simply exist as fashionable add-ons or productivity devices they are quickly emerging as frontline contenders in the early diagnosis of health issues, most notably heart-related ailments but how much can you really trust your smartwatch when it comes to life-threatening conditions such as a heart attack?

Smartwatches have developed at breakneck speed from basic step counters to high-tech wearable health trackers. The most widely used brands today have a set of tools that specifically track cardiovascular health. Features now include continuous monitoring of heart rate, heart rhythm monitoring, blood oxygen saturation, and even blood pressure in some versions.

How this is made possible is a technology known as photoplethysmography (PPG) — an optical sensor technique relying on LED light to measure changes in blood volume in the microvascular bed in the skin. As your heart beats, the sensor measures the change in reflection of light, providing information on your heart rhythm, rate, and at times, even your blood oxygenation levels.

Besides, certain smartwatches have single-lead electrocardiogram (ECG) features that give a better heart rhythm analysis and aid in detecting atrial fibrillation (AFib) — a precursor to stroke and heart failure.

Are Smartwatches Effective in Identifying Heart Attacks?

This is the most urgent query and the response isn't quite simple.

The short answer is, not yet. Although smartwatches are capable of detecting some warning signs and arrhythmias in the heart, they are not yet capable of diagnosing a heart attack in real-time with medical-grade accuracy. A heart attack (myocardial infarction) happens when blood supply to a region of the heart is obstructed, typically by a blood clot. Identification of this demands high-resolution and multi-lead ECGs, laboratory tests, and imaging — diagnostics well out of the capabilities of consumer-level wearables.

Dr. Peter Libby, a Harvard-affiliated Brigham and Women's Hospital cardiologist, describes in press release, "This technology is more a proof-of-principle rather than something that's clinically useful." His comments came after a small study discovered that ECG recordings from wearables can replicate hospital ECG equipment but with some limitations.

Simply, smartwatches can alert you to warning signs like an excessively high heart rate when you're resting, or symptoms matching AFib but cannot verify a heart attack. Nor can they substitute for immediate medical assessment.

What are the Benefits of Smartwatches?

Smartwatches are worth their price when it comes to real-time tracking and long-term heart care. Their potential to identify silent atrial fibrillation that may cause strokes or heart failure is noteworthy. Models that have been cleared by the Food and Drug Administration (FDA) for detecting AFib are recognized for their use in enabling users to access appropriate medical attention in a timely manner.

Companies such as Apple, Samsung, Fitbit, Google, and Withings have incorporated both PPG and ECG technologies. Some of them also provide tracking for blood oxygen saturation and blood pressure, thus adding to their functionality as personal health assistants.

However, it’s critical to understand that smartwatches operate under limitations — they provide preliminary insights, not definitive diagnoses. The data they collect can be shared with healthcare providers, enabling better-informed consultations, but they should never be used as a sole source of medical judgment.

As smartwatches get increasingly sophisticated, there is an increasing threat of false reassurance. Individuals might take "normal" readings as a go-ahead to put off medical intervention during true cardiac attacks. False alarms, on the other hand, can also cause undue stress and result in overtesting.

A balanced strategy is important. Experts suggest using smartwatches as an ancillary device, not a substitute for professional attention. If you have symptoms such as chest pain, difficulty in breathing, or inexplicable weakness — no matter what your smartwatch shows — get yourself medically checked.

How AI, Predictive Analytics Will Help In Medical Integration

The wearable technology future looks bright. Future developments in machine learning and artificial intelligence will seek to make smartwatches' predictive power stronger. These technologies can review trends over time, identify discrepancies, and even warn users before signs appear.

In addition, partnerships between medical institutions and technology companies might soon lead to equipment that is not only cleared by the FDA but clinically proven for more sophisticated diagnostics. We're close to an era when smartwatches might help prevent cardiovascular events — but that vision comes with aggressive testing, medical supervision, and regulatory clearance.

Smartwatches are precious health devices in this day and age of digitization, allowing users to be connected with their own well-being. In heart health, they provide actionable data and early detection that can lead to quicker medical attention.

In the detection or diagnosis of heart attacks, technology is lagging behind. Though the devices may lead to greater awareness and useful data, they must never be used in place of a doctor's know-how or emergency medical response.

If you've ever tried to lose weight with a partner, you've probably seen the maddening and frustrating difference- he goes without bread for a week and loses 10 pounds, yet you do the same thing and hardly move the needle. It's not in your head — research has shown that men lose weight quicker than women on diet and exercise alone. But in an ironic turn, a new generation of weight-loss medications is turning the tables.

GLP-1 receptor agonists, injectable medications like Wegovy (semaglutide) and Zepbound (tirzepatide) are performing far better for women than for men. New clinical trials at the European Congress on Obesity and in the New England Journal of Medicine have pointed to a recurring pattern: On average, women lose more weight than men with these drugs.

Why this occurs is still unclear, but the implications are large for future personalized weight loss plans.

During the 2024 European Congress on Obesity, scientists revealed results of a landmark clinical trial in The New England Journal of Medicine. The head-to-head trial pitted two of the most discussed GLP-1 injectables- Wegovy (semaglutide) and Zepbound (tirzepatide) against each other. More than 750 adults with excess weight were included, who received maximum tolerated doses of the two medications.

Tirzepatide unequivocally took the lead. Those on Zepbound lost a mean of 20% of their body weight at 72 weeks, in contrast to roughly 14% in those receiving Wegovy. There was an interesting twist, however. Zepbound, which is made by Eli Lilly, acts on two gut hormones (GIP and GLP-1), whereas Wegovy acts on just GLP-1. Double the action probably makes tirzepatide more effective.

But what amazed researchers the most was the gender difference: women always lost significantly more weight than men in both drug groups.

In previous semaglutide studies, women lost 11% of their body weight on average after two years. Men, meanwhile, lost about 8%. In tirzepatide studies, women lost as much as 28% of their initial weight—compared with 19% in men. This difference held even after accounting for lifestyle habits and adherence levels.

Dr. Louis Aronne, director of the Comprehensive Weight Control Center at Weill Cornell Medicine and the lead researcher, said, "Why this works better in women, I can't honestly tell you, but it's great. It has been seen again and again."

So, what is the secret behind this unexpected female advantage? Researchers point to a combination of things—biological, hormonal, and behavioral.

Why Women Respond Better To Weight-Loss Injections?

One hypothesis is based on dosage. These drugs are usually dispensed in standard doses, without consideration of the patient's body size. Because women are generally lighter than men, the same dose will be proportionally more intense in relation to their body weight. That may account for the more extreme outcomes in women.

In addition, women tend to possess more subcutaneous (or cutaneous) fat—fat that is held immediately below the skin—while men have more visceral fat, which is held deeper around internal organs. Perhaps these drugs act more effectively against subcutaneous fat, placing an advantage for women in terms of visible, quantifiable fat loss.

Behavioral influences may also be at work. Women are under more intense social pressure to remain thin, and this might make them more motivated to stick religiously to these treatment protocols. The injections take self-discipline—weekly injections, usually with side effects like nausea and fatigue—and an engaged patient is more likely to notice improvement.

The most convincing theory is perhaps one involving hormones—more precisely, estrogen. In animal studies, researchers have found that the combination of estrogen and GLP-1 has heightened effects on hunger and eating behavior. In humans, this could manifest as an increased response in premenopausal women, who have naturally elevated levels of estrogen.

If estrogen increases the effectiveness of GLP-1, this could help explain not only why women fare better, but also why responses might vary between young and older women. It also raises suspicions for women on hormone-suppressing treatments (like following breast cancer) or who are experiencing menopause, when estrogen levels fall naturally.

Mood, Metabolism, and the Future of Weight Loss

Interestingly, while GLP-1 medications are generally considered safe, some data suggest sex-based differences in mood responses. Some women report increased feelings of depression while on the medication—a side effect less common in men. Although not universal, these differences further highlight the need for more personalized, sex-aware treatment plans.

As scientists look further, the aim is to make the most of how such drugs are applied. Knowing why females gain more could lead to improved dosing regimens, enhanced non-responders' outcomes, and inform sex-, age-, and hormone-specific treatments.

GLP-1 drugs such as Wegovy and Zepbound are revolutionizing the face of weight management—and women can be at the forefront of that revolution. Although the specific reasons for the gender divide remain under study, this promising data is bringing new hope for women who've been frustrated by conventional methods of shedding pounds.

We still have much to learn, but this may be a turning point in the way we treat weight loss, particularly for women. As the science continues to develop, one thing is certain: The future of weight loss is no longer one-size-fits-all. It's personal, precision-driven, and—at last even more promising for women.
