In a revolutionary medical achievement, an Australian man with end-stage heart failure became the first person in the world to walk out of a hospital after undergoing a total artificial heart implant. The pioneering surgery, performed at Sydney's St. Vincent's Hospital, is a significant breakthrough in cardiology, providing hope for thousands of patients globally on the waiting list for heart transplants.

The patient, a 40-year-old man who wished to be unidentified, spent more than 100 days with the artificial heart before undergoing a donor heart transplant in early March. This historic success supports the promise of the BiVACOR Total Artificial Heart (TAH) as an alternative for long-term replacement for people with advanced heart failure.

Created by Dr. Daniel Timms, the BiVACOR TAH is a groundbreaking medical device designed to replace a failing human heart entirely. In contrast to conventional heart pumps that augment the heart's work, this device fully assumes the function of both ventricles and provides a constant and regulated flow of blood.

One of the most important technological advancements of the BiVACOR heart is its application of magnetic levitation. The machine has a single mobile component—a rotor that is kept suspended by magnets, doing away with mechanical bearings or valves that might break down with time. This not only increases durability but also replicates the natural rhythm of the human heart, providing perfect circulation to the body and lungs.

Cardiovascular diseases are the primary killer of humans worldwide and account for about 18 million deaths annually, states the World Health Organization. Heart failure, usually a complication of diseases like coronary artery disease, heart attack, and diabetes, makes the heart so weak it cannot pump blood effectively anymore.

For end-stage biventricular heart failure patients, donor transplants are their sole chance of survival. Alas, donor hearts are always in short supply compared to the demand. Within the United States alone, nearly 3,500 heart transplants were completed in 2024, with 4,400 new additions to the waiting list. That gap leaves thousands of patients with no viable chance of treatment and underscores the desperate need for such alternatives as artificial hearts.

Is This A Step Towards a Future Without Donor Dependency?

The BiVACOR TAH is still in the initial clinical trials, but its success to date seems to hold hope for future patients with serious heart disease. The recent Australian patient's case is the longest recorded survival time of a patient with the device, demonstrating its potential for sustaining a patient until they can receive a viable donor heart.

Victor Chang Cardiac Research Institute Professor Chris Hayward, who guided the recovery of the Australian patient, termed the advancement "a whole new ball game for heart transplants." According to him, within the next ten years, artificial hearts might be a practical option for patients who cannot be provided with a donor heart in time.

Though the Australian case is a milestone, the BiVACOR device has also been under trial elsewhere in the world. The U.S. Food and Drug Administration's Early Feasibility Study has already witnessed five patients getting the artificial heart implanted successfully. The first of these trials was conducted in July 2023, when a 58-year-old man at the Texas Medical Center got the implant. While he lived for just eight days before the transplant with a donor heart, the trial showed the device was capable of keeping critically ill patients alive.

Clinical trials will grow to 15 patients, with further tests on the device's safety and efficacy. Meanwhile, Monash University's Artificial Heart Frontiers Program, an AU$50 million ($31 million) project, is in full swing developing and commercializing three devices to treat heart failure, including the BiVACOR TAH.

Implications for the Future of Heart Failure Treatment

Successful use of the BiVACOR artificial heart has the potential to change the management of heart failure around the globe. For those not a candidate for heart transplants or with prolonged waiting lists, this technology represents a new hope. In contrast to mechanical pumps that merely supplement failing hearts, an entirely operational artificial heart might change survival rates and quality of life for thousands of patients.

Although more studies are required prior to widespread usage, the Australian breakthrough is an important milestone in the direction of a future when artificial hearts will be a normal treatment. The more technology is developed and more clinical trials that are conducted, the closer one comes to achieving the dream of replacing a defective human heart with a long-lasting, life-extending device.

American drugmaker Eli Lilly’s first oral pill for weight loss, Orforglipron, marketed as Foundayo, has been given the green signal by the US Food and Drug Administration (FDA).

Lilly is also known for injectable drugs like Zepbound for obesity and Mounjaro and Trulicity for diabetes.

Foundayo’s approval comes after the US FDA in December last year approved Novo Nordisk’s Wegovy pill — the first-ever GLP-1 pill for weight loss. The Danish drugmaker rolled out the pill in January this year.

Novo Nordisk was also the first to launch oral GLP 1 Rybelsus to treat type 2 diabetes. It was approved by the US FDA in September 2019.

In a statement, the US FDA said that "Foundayo has been approved for use in combination with a reduced-calorie diet and increased physical activity. The pill is targeted to reduce excess body weight and maintain weight reduction for the long term in adults with obesity or overweight".

Lilly said that the drug will be available from April 6 through its its direct-to-consumer platform LillyDirect at a cost of $149 per month for the lowest dose for self-pay customers — on par with Novo's pill. "Shortly after” it will be available through retail pharmacies and telehealth providers in the US.

"Today, fewer than 1 in 10 people who could benefit from a GLP-1 are taking one, held back by access, stigma, perceived complexity, or the belief that their condition isn't serious enough for treatment. We believe Foundayo can help level the playing field for those living with obesity or who are overweight and living with weight-related complications," said David A. Ricks, chair and CEO of Eli Lilly and Company.

"As a convenient, once-daily oral pill that delivers meaningful weight loss, this is obesity care designed for the real world," he added.

In these trials, 72 weeks of treatment with Foundayo, in combination with a reduced-calorie diet and increased physical activity, resulted in a statistically significant and clinically meaningful reduction in body weight.

Deborah Horn, Director of the Center for Obesity Medicine at McGovern Medical School at UTHealth Houston, stated that Foundayo “delivered an average of 12.4 percent weight loss at the highest dose in clinical trials – addressing both the clinical realities of obesity and the practical challenges patients face every day."

In addition, Foundayo also led to reductions in many markers of cardiovascular risk, including waist circumference, non-HDL cholesterol, triglycerides, and systolic blood pressure across all doses, Eli Lilly said.

How Foundayo Works

Lilly licensed Orforglipron, the main ingredient in Foundayo, from a Japanese pharmaceutical company in 2018.

As with the injectable forms of GLP-1s, Foundayo is available in six doses, ranging from 0.8mg to 17.2mg.

In consultation with their doctors, patients start with the lowest dose and gradually work up to higher doses; not everyone may need to reach the highest dose.

Unlike the Wegovy pill, people taking orforglipron do not need to restrict food or drink after taking the pill. Orforglipron is a small molecule that the body can absorb quickly and get into the blood, where it reaches the necessary tissues.

Foundayo: Side Effects

Foundayo is not safe for use in children and has an increased list of side effects, such as tumors in the thyroid, including thyroid cancer.

The drugmaker urged watching for possible symptoms, such as

• a lump or swelling in the neck,
• hoarseness,
• trouble swallowing
• shortness of breath.

• nausea,
• constipation,
• diarrhea,
• vomiting,
• indigestion,
• stomach (abdominal) pain,
• headache,
• swollen belly,
• feeling tired,
• belching,
• heartburn,
• gas,
• hair loss.

New Zealand has stepped up surveillance after the first detection of a dengue and Zika-carrying mosquito larvae in the country.

The larval species was confirmed as 'Aedes aegypti' — known to carry diseases including dengue fever, yellow fever, Zika, and chikungunya, across the globe.

As New Zealand does not normally have the mosquito species, the larvae detected were counted as "exotic".

The mosquito species did not cause any outbreak, but were spotted during a routine surveillance program in Auckland.

"The National Public Health Service has commenced a heightened surveillance and interception programme following mosquito larvae being collected from a routine surveillance trap at Queens Wharf, Auckland, on Monday 30 March," Health New Zealand said in a statement.

Health New Zealand reported that exotic species were occasionally found at ports and airports.

Not A Public Threat Yet

The health body noted that the larvae were not considered a public health or biosecurity threat yet because there was no indication they had become established.

But the agency aimed to continue "intensive monitoring for at least three weeks".

"The monitoring would take place within a 400m radius of the site where the larvae were identified. Health Protection Officers would place mosquito traps in the survey area," the statement said.

"These have been hidden away from plain sight so they are not disturbed, for example, in old tyres, bushes, or pools of water. We ask members of the public to avoid touching or disturbing these traps if they find them, as it may disrupt our monitoring and trapping efforts," medical officer of health Dr David Sinclair said.

Sinclair said New Zealanders were most at risk from diseases transmitted by mosquitoes when travelling overseas, including to Pacific Island countries and territories where dengue fever was known to be present.

Dengue Surging In 17 Countries

The US Centers for Disease Control and Prevention recently issued a travel alert of dengue outbreaks across 17 countries.

The CDC alert issued on March 23 identified 17 countries reporting an increased number of cases of dengue. These include: Afghanistan, Bangladesh, Bolivia, Colombia, Cook Islands, Cuba, Guyana, Maldives, Mali, Mauritania, New Caledonia, Pakistan, Samoa, Sudan, Timor-Leste, Vietnam, and the United States territories of American Samoa, Puerto Rico, and the US Virgin Islands, where local transmission is already common.

What Is Dengue?

Dengue is a disease caused by a virus spread through mosquito bites. It is transmitted through infected mosquitoes, primarily the species Aedes aegypti.

The breakbone fever is caused by an infection with any of four different dengue viruses. These include:

• Dengue virus type 1 (DENV-1 or DEN-1)

• Dengue virus type 2 (DENV-2 or DEN-2)

• Dengue virus type 3 (DENV-3 or DEN-3)

• Dengue virus type 4 (DENV-4 or DEN-4)

Common Symptoms of dengue include:

• Sudden onset of high-grade fever.

• Intense headache

• Severe muscle, joint, or bone pain.

• Skin Rash that often appears 2–5 days after the fever starts

• Nausea and Vomiting

• Minor bleeding

• Fatigue.

The COVID Cicada variant, currently circulating in 23 countries, is likely to affect children more than the previous variants.

Children have largely escaped severe illness from the SARS-COV-2 virus.

However, the new Cicada variant with around 75 genetic changes in its spike protein is likely to disproportionately affect children, as per an expert, who noted its presence in the UK.

“Some people have done analysis on this, suggesting it may be more prevalent among young children. Children get infections all the time, but this might be something to do with the fact that they have never been exposed to Covid vaccines," Prof Ravindra Gupta, of Cambridge University, who advised the UK government during the pandemic, was quoted as saying to The Mirror.

“So this is something we’re looking at in the lab to try and work out why. The problem with this is that it is an infection that spreads fast. Eventually, it ends up in someone vulnerable," he added.

Key Symptoms

Symptoms seem to be similar to those of other recent variants and include

• sore throat,
• cough,
• congestion,
• fatigue,
• headache
• fever.

What Do The 75 Genetic Changes Mean?

Cicada, a descendant of the Omicron variant that emerged in 2021, was first detected in South Africa in 2024. However, it disappeared soon after, only to emerge early this year.

Prof Gupta told the publication that “the Cicada variant developed the 75 mutations to escape immunity, and it evolved by incubating a single patient for over a year”.

"This 'patient zero' would have been unable to clear the virus due to a compromised immune system," due to HIV or anti-cancer drugs.

Further, he explained that due to 75 mutations to the spike protein, the body’s antibodies will take a longer time to fight the Cicada variant.

However, there is no evidence yet that it is likely to cause more severe disease.

Will The Cicada Variant Cause Severe Illness?

The Cicada variant is particularly concerning as it provides no immune protection to people with previous infection or even vaccination.

Yet, the World Health Organization and health experts advise that existing COVID vaccinations can help prevent severe illness and hospitalization.

"It would appear that all the protections we have from our experience with the virus and with vaccines probably offer more limited—not zero—but more limited protection against this strain," Dr. William Schaffner, professor of infectious diseases at Vanderbilt University Medical Center, was quoted as saying by Time.

How To Safeguard

Dr. Sai Balasubramanian, a doctor and healthcare strategy executive, writing in Forbes, stressed the need to follow COVID practices such as masks and hand hygiene.

"Healthcare professionals recommend taking general precautions, similar to those used to prevent most viral transmission: get vaccinations when appropriate, wear masks in crowded areas or indoors where there is a high risk of transmission," he said.

He also urged “avoid individuals who have known illness or infections, wash hands frequently, and continue to stay apprised of local community guidelines and the infection spread”.
