Cigarettes with ultralow nicotine levels are now being called the game-changer in the fight against smoking. If you are having trouble in quitting smoking, then, it is for you, that soon the Biden White House is expected to formally propose a plan that will order cigarette nicotine levels to be reduced, reports The Washington Post. For now though, it has been a failure, as these cigarettes, also known as VLN cigarettes that stands for very low nicotine are only available in 5,100 stores in 26 states. This is a very small fraction of the overall market for cigarettes. The company that makes it, 22nd Century, is struggling not because of the low supply, but also from the advocates who have long believed slashing nicotine levels altogether.

The Advent and ideation

Nicotine is a chemical that is produced naturally from tobacco that makes the cigarette and also keeps people hooked. While it is believed that it makes people alert, and get the "hit" to keep them going, it exposes the users to harmful substances, carcinogens, and increases the risk of heart disease, lung cancer, and other illness.

Ultralow-nicotine cigarettes, like the VLN brand, contain about 95% less nicotine than the regular cigarettes. The idea is quite simple: without the addictive grip of nicotine, smokers will find it easier to quit. Research too has shown some promise. For instance, the studies funded by the National Institute on Drug Abuse revealed that very low nicotine cigarettes reduced addiction potential significantly without having users to increase their smoking frequency. However, the problem is, why would anyone choose for a low-nicotine that does not make them feel the same way, when the high-nicotine cigarette is right next to it, making them feel the same way, with the same alertness, sold at the same price.

“It’s very hard to imagine someone actively choosing to continue to use a low-nicotine product for the same price when a high-nicotine product is right next to it,” said Eric Donny, a Wake Forest University School of Medicine nicotine researcher.

No wonder, the experiment with low nicotine product by Philip Morris' Next cigarettes in the 1980s and Vector Tobacco's Quest brand in the early 2000s, flopped.

FDA's Role in the Push

The Food and Drug Administration (FDA) has supported the development of such products, even allowing VLN cigarettes to be marketed as lower-risk options. However, these products remain a niche market, available in only a fraction of U.S. stores.

Recently, the Biden administration has considered a bold step—mandating a dramatic reduction in nicotine levels for all cigarettes sold in the United States. Supporters believe this move could save millions of lives, while critics, including tobacco companies, warn of potential unintended consequences.

What Could Be The Challenges?

Resistance from Big Tobacco Companies: They could argue that slashing nicotine levels could backfire. Their claim is, smokers will turn to black markets or smoke more to satisfy their cravings, which may lead to greater exposure to harmful substances.

Consumer Reluctance: History is proof to the instances of smokers being hesitant to embrace the low-nicotine products.

Political Hurdle: It may face political roadblocks, as under the Trump administration, plans to cut nicotine were shelved.

Could Low-Nicotine Cigarettes Be The Solution?

Advocates believe that ultralow-nicotine cigarettes could be a game-changer, comparing them to decaf coffee or non-alcoholic beer—products that reduce harm while offering a similar experience.

Some experts warn that a black market for traditional cigarettes could undermine these efforts. They also stress the need for safer alternatives, such as vaping products, to support smokers transitioning away from traditional cigarettes.

Pancreatic cancer is one of the most difficult cancers to detect in its early stages. By the time it is diagnosed, the disease may have already spread, limiting treatment options and lowering survival.

Now, a novel blood test called Panxeon, developed by researchers at City of Hope, could offer a way to detect pancreatic cancer earlier.

Panxeon is an investigational liquid biopsy designed to detect pancreatic cancer, including stage 1 and 2 disease, using a blood sample.

The test also showed potential for identifying high-grade dysplasia, a precancerous condition sometimes considered “stage 0” pancreatic cancer.

In a study of nearly 1,800 patients across the US, Europe and Asia, published in Nature Medicine, the blood test correctly identified stage 1 and 2 pancreatic cancer in 87% of cases. Its false-positive rate was 3% among people in low-risk groups and 16% among those in high-risk groups.

Panxeon also detected high-grade dysplasia more than 64% of the time. This could help doctors identify which pancreatic cysts may require closer monitoring or further intervention before invasive cancer develops.

How Does Panxeon Detect Pancreatic Cancer?

Pancreatic cancer has one of the lowest survival rates among cancers. Only 14% of patients survive five years after diagnosis, according to the US National Cancer Institute.

Panxeon assesses three biological signals associated with pancreatic cancer: circulating microRNAs, exosomal microRNAs and a protein called CA19-9.

The test then uses artificial intelligence to combine these measurements into a single score estimating a person's risk of pancreatic cancer.

“Pancreatic cancer remains so deadly largely because we find it after the window for cure has begun to close,” said senior author Ajay Goel, chair of the Department of Molecular Diagnostics and Experimental Therapeutics at City of Hope.

“For patients, these findings represent progress toward finding pancreatic cancer before symptoms appear and while more treatment options remain available,” he added.

According to the researchers, Panxeon is the first investigational test to combine these three biomarkers into a single blood test.

However, Panxeon is not intended to replace imaging or other diagnostic tests. Instead, it could potentially help identify people at higher risk who need further evaluation, said Goel.

Who Could Benefit From the Test?

Early detection of pancreatic cancer has been a longstanding research challenge, with previous blood-based tests failing to provide sufficient accuracy.

The researchers said Panxeon's approach differs by combining multiple biomarkers and evaluating the test in people with risk factors such as inherited or familial risk, pancreatic cysts and chronic pancreatitis, rather than relying only on healthy controls.

“Most biomarkers tell you one part of the story. Combining multiple biological signals gives us a clearer picture of what may be happening in the pancreas,” Goel said.

People who may potentially benefit from such testing include those with an inherited risk or family history of pancreatic cancer, pancreatic cysts or chronic pancreatitis.

These groups are often monitored using imaging and other tests. A reliable blood test could eventually help identify who needs further evaluation.

“A stage shift is not just a statistic,” Goel said. “The earlier we find pancreatic cancer, the greater the chance that meaningful intervention is still possible.”

Pancreatic cancer can begin with few or nonspecific symptoms, making early diagnosis difficult. Symptoms may become more apparent as the disease progresses.

Symptoms that should not be ignored include:

• Abdominal or back pain
• Unexplained weight loss
• Jaundice
• Changes in urine or stool.

Newly released national sexual health data shows that Australia is seeing an alarming rise in STIs like syphilis and gonorrhoea. The data from Kirby Institute at UNSW Sydney shows that diagnoses have increased by more than 50% over the past decade.

In 2025, Australia recorded 5,986 syphilis diagnoses and 42,393 gonorrhoea diagnoses, with rates of both infections shooting up by more than 50% since 2016.

Apart from the sharp rise in cases, one pattern that has drawn attention is the difference in the number of infections between men and women. Syphilis diagnoses among women increased 167% over the past decade, compared with a 39% increase among men.

Health experts say the rise is especially alarming as syphilis, when left untreated, can cause miscarriage, stillbirth, congenital syphilis and infant death.

Signs Of Syphilis Can Vanish Without Actually Leaving The Body

Syphilis is caused by the bacterium Treponema pallidum and the infection unravels in stages. The first stage causes a painless sore, called a chancre, typically at the site where the bacteria entered the body. The sore can occur around the genitals, anus, rectum, lips or mouth and may disappear on its own within weeks.

The disappearance of that sore could be misleading because when it heals, it does not mean that the infection has not necessarily gone away.

Without treatment, syphilis can progress to a second stage, which comes with a rash, swollen lymph nodes, fever, fatigue, and other symptoms. These symptoms can also eventually disappear.

If left untreated, the infection can then enter its latent stage, when a person has no visible signs or symptoms. This is what makes syphilis particularly difficult to detect.

During latent syphilis stage, the bacteria remain in the body even though the person may feel completely well. According to the US Centers for Disease Control and Prevention, untreated syphilis can remain in the body for years.

Rising Syphilis Cases In Women Women May Impact Pregnancy

The latest Australian data show men accounted for 78% of syphilis diagnoses in 2025, but the much faster increase among women is raising particular concern because an infected pregnant woman can pass the bacteria to her unborn baby.

Dr Skye McGregor, an epidemiologist at the Kirby Institute said, “It’s really concerning because the rise among women has contributed to syphilis in pregnancy, which can cause miscarriage, stillbirth, congenital syphilis and infant deaths,” McGregor said. “These are really substantial impacts on infants, but also the community as a whole. Across that same 10-year reporting period, there were 113 congenital syphilis cases and, tragically, 40 of those infants died.”

Australia recorded 14 cases of congenital syphilis in 2025. Over the past decade, there have been 113 reported congenital syphilis cases, with 40 resulting in infant deaths.

The infection is preventable from reaching the baby when it is identified and treated during pregnancy. To curb the same, Australia has recently updated national guidelines to recommend at least three syphilis tests during pregnancy, reflecting concern about rising infections.

What Happens If Syphilis Is Left Untreated For Years?

Not everyone with untreated syphilis develops latent-stage disease. But in some people, the infection can eventually damage multiple organs.

Tertiary syphilis can affect the heart and blood vessels, brain and nervous system, and several other organs. It can emerge 10 to 30 years after the original infection and can cause severe disability or death.

Syphilis can also affect the nervous system, eyes or ears at different stages of infection. Neurosyphilis can cause headaches, weakness, problems with movement, confusion or cognitive changes.

Ocular syphilis can cause vision problems and potentially permanent vision loss, while otosyphilis can cause hearing loss, tinnitus or dizziness.

India’s Ministry of Health and Family Welfare has issued an advisory stating that stem cell therapy should be used as standard care only for diseases or indications approved by the Ministry.

The advisory reiterates the existing regulatory framework governing stem cell research and therapy.

What Does The Advisory Say?

The advisory directs that stem cell therapy for Autism Spectrum Disorder (ASD) be restricted to approved clinical trials.

This aligns with the National Guidelines for Stem Cell Research, 2017, issued by the Indian Council of Medical Research (ICMR) and the Department of Biotechnology (DBT), along with other applicable government instructions.

The advisory also says unproven stem cell interventions, including those for ASD, should not be offered as “routine, standard or commercial clinical services.”

“All States and Union Territories must adopt the Clinical Establishments (Registration and Regulation) Act, 2010, regarding regulation of stem cell therapy,” the Ministry said.

The directions apply to government and private clinical establishments involved in stem cell research, treatment, promotion or administration.

The Supreme Court had earlier ruled against the use of stem cell therapy for autism outside approved clinical trials. The National Medical Commission (NMC) has also warned doctors and hospitals against offering it as routine treatment for ASD.

Action Against Violations

The Ministry has asked States and Union Territories to ensure that hospitals, clinics and other establishments involved in stem cell research or treatment comply with the regulatory framework.

The Supreme Court, in its January 30, 2026 judgment, said violations can lead to professional misconduct proceedings, as well as action under the Clinical Establishments Act, including cancellation of registration and penalties.

In its September 5, 2026 advisory, the National Medical Commission (NMC) said stem cell therapy can be offered as standard clinical care only for approved indications.

Unauthorized administration, prescription, promotion or advertising of stem cell therapy beyond approved indications may amount to professional misconduct, it said.

State Medical Councils have been asked to examine alleged violations and take disciplinary action where professional misconduct by a registered medical practitioner is established after due process.

Which Diseases Can Be Treated With Stem Cells?

Earlier this year, ICMR Director-General Dr Rajiv Bahl told the NMC that stem cell treatment could be used in regular medical practice only for 32 government-approved diseases.

These include:

• Acute myeloid leukemia
• Thalassemia
• Multiple myeloma
• Aplastic anemia
• Myelofibrosis
• Germ cell tumors

The ICMR DG asked doctors not to offer stem cell therapy for diseases outside the approved list. Current international guidelines also do not recommend stem cell therapy as a treatment for ASD.

What Did The Supreme Court Say?

In January, a Supreme Court bench comprising Justice JB Pardiwala and Justice R Mahadevan said stem cell therapy lacks “scientific support” and has not been recognized as a sound medical practice backed by empirical evidence.

The Bench ruled that “every use of stem cells in patients outside an approved clinical trial is unethical and shall be considered as malpractice.”

The Court said stem cell therapy can still be studied through monitored clinical research trials, and patients can participate in approved and regulated trials.

What Is Stem Cell Therapy?

Stem cell therapy, also called regenerative medicine, uses stem cells to repair or replace damaged tissues.

While stem cell therapy is used for certain blood cancers and blood disorders, there is no established scientific evidence supporting its use as a treatment for autism.

Stem cell therapy remains vastly unregulated in India, and some private labs have been making money by promising treatment for autism, according to experts.
