Many of us believe that we are great drinkers and that alcohol does not affect us as much. People who are able to drink without showing any sign of inebriation are known as social drinkers. In short, they are not addicted to alcohol but will not turn down the opportunity to have a good time! While it may seem like it doesn’t affect you, new studies suggest that it is just an illusion, even if you have high tolerance, alcohol affects your cognitive and motor functions more than you think.

The study reveals the below implications and techniques:

  • Researchers used a new MRI technique to precisely measure brain electrical activity.
  • By comparing brain scans before and after drinking, scientists identified specific areas affected by alcohol and how much brain activity slowed down.
  • Participants were chosen to be regular social drinkers without alcohol addiction, ensuring the study focused on the effects of alcohol alone.
  • MRI technology provided reliable data on brain activity changes caused by alcohol consumption.

How does the brain react to alcohol?

The human brain is a complex network of billions of neurons that communicate through electrical impulses. Brain conductivity refers to the efficiency with which these electrical signals travel through brain tissue. It's akin to the speed and clarity of a digital signal through a wire. In layman terms, your brain must function in its peak condition as it is essential for various cognitive processes, including memory, attention, decision-making, and motor control.

Think of it as the foundation for your brain's performance. When brain conductivity is high, information flows smoothly, and that helps your brain in rapid processing and response. On the other hand, low conductivity can hinder cognitive function, leading to slower thinking, impaired memory, and difficulties with coordination.

A study conducted at the Neuroscience Research Australia (NeuRA) and UNSW Science unveiled a startling connection between alcohol consumption and brain conductivity.

What is the connection between alcohol consumption and brain activity?

While many people brush off the effects of alcohol as temporary changes in behaviour, the reality is much more complex. Beyond the obvious impacts on coordination and judgment, alcohol significantly alters brain function. Alcohol dramatically slowed down brain activity, especially in areas responsible for decision-making, planning, and physical coordination. This decline was so significant that it resembled the brain changes seen in normal ageing. This means even one drink could temporarily accelerate the ageing process of your brain.

Alcohol and Brain activity: What does the study Imply?

The implications of this research are far-reaching. It provides compelling evidence that alcohol consumption has a direct and measurable impact on brain function. The discovery that alcohol can significantly reduce brain conductivity opens new avenues for understanding the neurocognitive effects of alcohol abuse and dependence. While you may not feel like alcohol is affecting you and you have a high tolerance, it most definitely changes and affects your decision-making abilities and impulse control.

Furthermore, the MRI technique employed in the study could be a valuable tool for assessing the impact of other substances on the brain and for developing interventions to mitigate alcohol-related brain damage.

WHO Cancer Agency Flags 3 Common Medicines As Carcinogenic: What It Means For Millions Of Patients

Updated Aug 5, 2026 | 04:00 PM IST

SummaryAll three medicines —hydrochlorothiazide, voriconazole, and tacrolimus—are included on the WHO Model List of Essential Medicines and are prescribed to millions of people worldwide for treating hypertension, serious fungal infections, and preventing organ transplant rejection. Medical experts urge patients not to stop taking these medicines without consulting their doctor.
WHO Cancer Agency Flags 3 Common Medicines As Carcinogenic: What It Means For Millions Of Patients

The International Agency for Research on Cancer (IARC), the World Health Organization's (WHO) cancer research agency, has classified three widely used medicines—hydrochlorothiazide, voriconazole, and tacrolimus—as Group 1 carcinogens, meaning they are "carcinogenic to humans."

All three medicines are included on the WHO Model List of Essential Medicines and are prescribed to millions of people worldwide for treating hypertension, serious fungal infections, and preventing organ transplant rejection.

A Group 1 classification means there is sufficient scientific evidence that an agent can cause cancer in humans under certain circumstances. However, it does not indicate how likely a person is to develop cancer while taking the medicine as prescribed. The actual risk depends on factors such as the dose, duration of use, individual health, and other risk factors.

Which Medicines Have Been Classified as Carcinogenic?

Hydrochlorothiazide: It is a thiazide diuretic commonly prescribed to treat essential hypertension. Although newer blood pressure medications are increasingly used, it remains a widely prescribed treatment because of the global burden of hypertension.

Voriconazole: It is a broad-spectrum triazole antifungal medicine used to treat invasive aspergillosis and other serious fungal infections, particularly among transplant recipients and other immunocompromised patients.

Tacrolimus: It is an immunosuppressive medicine used to reduce the risk of organ rejection in adult and pediatric transplant recipients and to prevent graft-versus-host disease following stem cell transplantation. Topical tacrolimus is also used as a second-line treatment for atopic dermatitis and vitiligo when topical corticosteroids are unsuitable.

Why Did IARC Classify Them as Carcinogenic?

"The IARC Monographs Working Group reviewed evidence from epidemiological studies, cancer bioassays in experimental animals, and mechanistic studies to assess the carcinogenic hazard to humans of exposure to these agents and concluded that hydrochlorothiazide, tacrolimus, and voriconazole are all carcinogenic to humans (Group 1)," the IARC said.

  • Hydrochlorothiazide has been linked to squamous cell skin cancer and lip cancer because it increases the skin's sensitivity to sunlight.
  • Voriconazole is associated with squamous cell carcinoma of the skin through the phototoxic effects of one of its metabolites.
  • Tacrolimus has been linked to non-Hodgkin lymphoma and post-transplant lymphoproliferative disorders, largely due to its immune-suppressing effects.

What Does This Mean for Patients?

Dr. Shyam Aggarwal, Chairman, Medical Oncology, Sir Ganga Ram Hospital, told HealthandMe that the classification identifies a cancer hazard, not the level of cancer risk associated with normal therapeutic use.

"The IARC underlines that this Group 1 listing identifies a cancer hazard—the potential of an agent to cause malignancy rather than measuring how great the actual risk is when the medicines are taken at normal therapeutic doses. All three remain listed as essential medicines by WHO, reflecting their critical role in treating serious illness," he said.

Dr. Aggarwal stressed that patients should not stop taking these medicines without consulting their doctor.

"Abruptly stopping any of these agents can result in dangerous rises in blood pressure, uncontrolled infection, or transplant failure. The recommended course is to speak with the treating physician, adopt rigorous sun-protection habits if taking hydrochlorothiazide or voriconazole, and maintain regular surveillance for those receiving tacrolimus after transplantation," he added.

No Need to Panic

Dr. Tushar Tayal, Associate Director – Internal Medicine, CK Birla Hospital, Gurugram, told HealthandMe the reclassification should not be a cause for alarm.

According to him, the concern relates to long-term cumulative exposure rather than a single dose. Stopping treatment abruptly could pose a much greater immediate risk, including uncontrolled hypertension, severe infection, or transplant rejection.

What Should Patients Do?

  • Do not stop or change your medication on your own.
  • Consult your treating physician before making any changes to your treatment.
  • Discuss whether regular skin examinations or an alternative treatment plan may be appropriate based on your individual risk.
  • Use sun protection if you are taking hydrochlorothiazide or voriconazole, as advised by your doctor.
  • Attend regular follow-up appointments, especially if you are taking tacrolimus after an organ transplant.

A UK-based surgeon from Egypt has been permanently barred from practising medicine after a medical tribunal found that he made a catastrophic blunder during an emergency bowel surgery.

Dr Yasser Adly Abdel Rahman, who was working as a locum surgeon at Royal Oldham Hospital in Greater Manchester, mistakenly connected the wrong parts of a patient’s digestive system, a procedure experts described as “not known to man.”

Here's What Happened

Dr Rahman carried out the operation on a young man in August 2020. Instead of restoring the patient’s bowel, the surgery created a “closed loop” that caused contents of the bowel to flow back into the stomach.

The error left the patient in unimaginable pain and in a condition deemed “not compatible with life.”

According to findings by the Medical Practitioners Tribunal Service (MPTS), the patient was left feeling severe pain, vomiting and an inability to pass stool after the surgery.

A second surgeon later performed emergency corrective surgery, creating a stoma and saved the patient’s life.

The tribunal heard that Dr Rahman failed to realise the seriousness of the patient’s deteriorating condition and did not adequately respond to concerns raised by the patient’s family and medical colleagues.

An expert from the General Medical Council (GMC) described the erroneous procedure as “as bad as it gets” and said the surgical connection was “not known to man.”

The Surgeon Was Struck Off From The UK Medical Register

The tribunal ruled that Dr Rahman’s actions amounted to serious professional misconduct.

It also found that, in 2021, after restrictions were placed on his medical practice, he breached them by taking up a locum job in Affidea Express Care Clinic in Ireland in 2022.

Dr Rahman was absent at the misconduct hearing and instead maintained that he was a victim of a witch hint and had been made a “scapegoat.”

But, the tribunal concluded that his incompetence, failure to accept responsibility and repeated breaches of regulatory conditions meant he posed an ongoing risk to patients. He has now been permanently removed from the UK medical register.

What Is A “Closed Loop” Bowel Obstruction?

A closed loop bowel obstruction occurs when a section of the intestine is blocked at two points, restricting its contents. This can fatally cut off blood supply to the bowel, causing tissue death, perforation, infection and sepsis if not treated urgently.

In this case, the incorrect surgical connections diverted bowel contents back into the patient’s stomach instead of allowing them to pass normally through the digestive tract, creating a life-threatening emergency that required immediate corrective surgery.

While surgical complications can occur even in experienced hands, medical experts told the tribunal this error was far from acceptable.

The case has also drawn attention because the surgeon allegedly ignored warning signs after the operation. He later breached restrictions placed on his medical licence by taking up a job elsewhere. These factors ultimately contributed to the decision to strike him off from the UK register permanently.

About Dr. Yasser Adly Abdel Rahman

Dr Rahman qualified in 1993 from Ain Shams University in Cairo, Egypt. He trained as a general and colorectal surgeon.

He later worked in the UK as a locum consultant, meaning he was employed on temporary contracts rather than in a permanent consultant position.

At the time of the incident in August 2020, he had only been working at Royal Oldham Hospital in Greater Manchester for a few days before performing the emergency bowel surgery.

SummaryChhattisgarh government has also banned the sale and use of analogue paneer across the state. Adulterated paneer can pose serious health risks, especially if manufactured using unsafe ingredients.
Maharashtra Becomes Second Indian State To Ban Sale Of Fake Paneer: Here's Why It Can Be Harmful

After several months of a statewide crackdown on food adulteration, Maharashtra has now banned the manufacture and sale of non-dairy paneer, commonly known as analogue paneer or analogue cottage cheese.

The move follows multiple raids on fake paneer manufacturing units and the seizure of large quantities of spurious dairy products.

Earlier this week, the Chhattisgarh government also banned the sale and use of analogue paneer across the state. The Health Department announced that the product will no longer be permitted in markets, hotels, restaurants or roadside eateries. Maharashtra has now become the second Indian state to impose such a ban.

Ban on Manufacture and Sale of Analogue Paneer

The order, issued by Food Safety Commissioner Tukaram Mundhe in Maharashtra, prohibits the manufacture, processing, packing, storage, transportation, wholesale and retail sale, distribution, and offering for sale of analogue or non-dairy paneer across the state.

Violations can attract up to six months' imprisonment and a fine of Rs 1 lakh under the Food Safety and Standards Act, 2006.

In cases where the consumption of unsafe food results in death, the law provides for life imprisonment and a minimum fine of Rs 10 lakh.

As per the Maharashtra Maharashtra Food and Drug Administration (FDA), strict legal action will also be taken against individuals or establishments selling analogue paneer as genuine dairy paneer for misleading consumers.

Why Was the Ban Imposed?

The decision follows findings from the Maharashtra FDA's year-long enforcement and surveillance drive.

According to the regulator, routine inspections, food sampling and awareness campaigns failed to curb the sale of analogue paneer.

"The proportion of non-conforming samples remained persistently high at 35.4 per cent of the samples analysed," the FDA order stated. Between April 1, 2025, and March 31, 2026, the FDA collected paneer and analogue paneer samples from across the state.

Further, the FDA stated that its year-long inspections found that hotels, restaurants, caterers and other food establishments were routinely using analogue paneer instead of genuine paneer without informing customers through menus, invoices or display boards.

Authorities also found that analogue paneer was often transported and sold without original packaging, mandatory labels, invoices, batch identification or traceability documents, making it difficult to identify its source and increasing risks to public health.

Analogue vs Diary Paneer

Traditional paneer is a fresh, soft, non-melting cheese commonly used in Indian cuisine. It is made by curdling milk with acidic ingredients such as lemon juice, vinegar, or citric acid, separating the curd from the whey. The curds are then drained and pressed to remove excess water.

On the other hand, analogue paneer is made using vegetable fats or oils, starches and other non-dairy ingredients instead of milk fat.

As per the Food Safety and Standards Authority of India (FSSAI) regulations:

  • Paneer must be made from milk.
  • It should not contain added starch, non-dairy fats, or synthetic ingredients.
  • Analogue paneer can be sold only if it is clearly labelled as "analogue" or "imitation" and not marketed as genuine paneer.

How to Identify Fake Paneer

FSSAI and experts recommend these simple checks:

  • Check the texture: Genuine paneer is firm with a fresh milky smell. Fake paneer tends to crumble or melt quickly when heated.
  • Read the label: Products made with non-dairy substitutes must be labelled as "analogue" or "imitation".
  • Iodine test: Boil a piece of paneer, add a few drops of iodine tincture. If it turns blue, it may indicate the presence of starch.
  • Toor dal test: Boil the paneer, cool it in water, add some toor dal and leave it for 10 minutes. If the water turns light red, it may indicate adulteration.

What Are the Health Risks?

Health experts warn that adulterated paneer can pose serious health risks, especially if manufactured using unsafe ingredients.

Possible risks include:

  • Food poisoning
  • Vomiting and diarrhea
  • Allergic reactions
  • Kidney damage from nephrotoxic compounds
  • Liver damage due to toxin accumulation
  • Exposure to chemicals such as formalin, detergents or industrial stabilizers, if used in illicit preparations
Children, pregnant women and people with pre-existing medical conditions are considered particularly vulnerable.
