Smokers who make the decision to quit will experience immediate health benefits, including a rapid reduction in their risk of atrial fibrillation (A-Fib), according to new research published in JACC: Clinical Electrophysiology. The study, conducted by Dr. Gregory Marcus, a cardiologist at the University of California, San Francisco, offers compelling evidence for smokers to quit, showing that it’s never too late to avoid the damaging effects of smoking on heart health.

Dr. Marcus, the senior author of the study, emphasized that A-Fib can be prevented even in individuals who have smoked for years. "The findings provide a compelling new reason to show current smokers that it’s not too late to quit, and that having smoked in the past doesn’t mean you’re ‘destined’ to develop A-Fib," Marcus explained. "Even for the current and longtime smoker, A-Fib can still be avoided."

What is Atrial Fibrillation (A-Fib)?

"There’s strong evidence that smoking increases the risk of A-Fib," Marcus said. "But the benefits of quitting smoking have been less certain." With this in mind, his team sought to determine whether quitting could significantly lower a person’s risk of developing A-Fib, or if the risk would remain the same.

The research team analyzed data from over 146,700 current and former smokers, tracking their smoking habits and health over a 12-year period using data from the UK Biobank database. The results were promising: former smokers had a 13% lower risk of developing A-Fib compared to current smokers, while those who quit during the study saw an 18% reduction in their risk.

"This is likely a testament to the potency of reducing atrial fibrillation risk pretty shortly after quitting," Marcus said in a statement from the American College of Cardiology.

The findings highlight the importance of quitting smoking, not only for general health but specifically for reducing the risk of serious heart conditions like A-Fib.

Tips for Quitting Smoking

Quitting smoking is one of the most effective ways to lower the risk of A-Fib and improve overall heart health. While it can be challenging, the benefits of quitting are clear and immediate. Here are some tips to help you quit smoking successfully:

1. Choose a specific date to quit smoking and stick to it. Prepare yourself mentally and physically for this change.

2. Reach out to family, friends, or a support group to help keep you accountable. Sharing your goals with others can provide encouragement.

3. Options like nicotine patches, gum, or lozenges can help ease withdrawal symptoms and reduce cravings.

4. Identify situations that make you want to smoke, such as stress or social gatherings, and find healthy ways to cope with them.

5. Regular exercise can help distract you from cravings and improve your mood during the quitting process.

6. Drinking water can help flush nicotine out of your system faster, reducing cravings.

7. Activities like yoga, meditation, or deep breathing exercises can help manage stress, a common trigger for smoking.

Quitting smoking offers immediate and significant benefits, particularly in reducing the risk of atrial fibrillation. The latest research provides smokers with more motivation to quit, showing that it's never too late to take control of their heart health.

Delhi woke up to a slightly lower levels of AQI on Sunday Morning, November 30, as city's AQI dropped to 269 at 7am down from 305, which was recorded at 4pm on Saturday. This now falls under the "poor" category. However, experts say that the relief is temporary.

Many health experts and those who have studied the impact of pollution on humans have pointed out that anything above 300 is harmful to humans. These harms are not just limited to respiratory illnesses, and to lungs, causing lung cancers, but can also be the reason why obesity is on the rise.

Can Air Pollution Cause Obesity?

As per a 2021 study titled Effect of Air Pollution on Obesity in Children: A systematic Review and Meta-Analysis, there is a connection between air pollution and weight gain through biological behavioral mechanism. The major pollutants causing obesity are nitrous oxides, nitrogen dioxide, ozone, and particulate matter.

These could lead to systematic inflammation and metabolic disturbances, which can lead to weight gain and obesity. The study mentions that fine particulate matter [PM2.5], when it enters our body, it influences the metabolism rates.

The 2021 study also revealed that increase in air pollution, and road traffic noise was also associated with childhood obesity.

Another 2011 study titled The influence of air pollution on cardiovascular and pulmonary function and exercise capacity: Canadian Health Measures Survey (CHMS), found that air pollutants may indirectly impact body weight by raising the risk of chronic conditions like blood pressure, heart diseases or lung diseases. "Exposure to higher concentrations of air pollution was associated with higher resting blood pressure and lower ventilatory function. Ozone was associated with reduced exercise capacity," researchers of the study wrote.

The latest study published in 2024 titled The association between air pollution and obesity: an umbrella review of meta-analyses and systematic reviews, found that air pollution can impact metabolic function by influencing inflammation in fat tissue. It leads to an increase in oxidative stress and alters one's dietary habits.

Pollution And Women's Health

This does not end here, air pollution could also negatively impact women. As Dr Anuradha Kapur, Principal Director (Obstetrics & Gynaecology) and Head of Unit, Max Smart Super Speciality Hospital, Saket says, "Environmental pollutants, such as pesticides and microplastics, can affect reproductive health and hormone regulation, potentially impacting menstrual cycles."

Dr Sonam Simpatwar, Gynaecologist with a diploma in reproductive medicine, practising at Central Railway Hospital, Mumbai further explained how pollutants impact women's health:

Endocrine Disruptors: Chemicals found in pollution, plastics, and pesticides can mimic or interfere with hormones, potentially affecting menstrual cycles.

Climate Change: Rising temperatures, extreme weather events, and changes in water quality can impact food production, nutrition, and overall health, which can indirectly affect menstrual health.

Stress: Environmental stressors, such as pollution and climate change, can lead to increased stress, which is known to influence menstrual cycles.

"It's important to note that these are potential factors, and more research is needed to fully understand their impact on menstrual health," she said.

High levels of low-density lipoprotein cholesterol (LDL-C), commonly called "bad" cholesterol, continue to be a leading modifiable risk factor for atherosclerotic cardiovascular disease (ASCVD) worldwide. While statins and other cholesterol-lowering medications have significantly improved treatment, many patients still do not reach the LDL-C targets recommended by guidelines.

However, a new potential solution has emerged. The experimental daily oral drug called enlicitide, part of the PCSK9 inhibitor class, demonstrated in a key Phase 3 study (CORALreef Lipids) a reduction in LDL-C of about 55.8% at 24 weeks, with post-hoc analysis suggesting reductions up to 59.7% compared to a placebo.

Statins Vs Enlicitide

Statins are the standard first-line treatment for high LDL-C and have strong evidence for lowering the risk of cardiovascular events. Yet, many patients either cannot tolerate high doses or still have elevated cholesterol levels. Injectable PCSK9 inhibitors, which are monoclonal antibodies, address this gap and can lower LDL-C by up to 70% but are expensive, require injections, and have limited uptake.

Introducing an oral PCSK9 inhibitor could make powerful LDL-C reduction more accessible. According to trial data, enlicitide may achieve reductions similar to injectable options while being more convenient and potentially more widely available.

Enlicitide: A Potential Breakthrough for "Bad" Cholesterol

The CORALreef Lipids Phase 3 study involved 2,912 adults at risk of or with established ASCVD who were either already on lipid-lowering therapy or unable to take statins. Participants were randomly assigned to receive a daily 20 mg dose of oral enlicitide or a placebo. At 24 weeks, the main analysis showed an average LDL-C reduction of 55.8%, with a post-hoc reanalysis estimating 59.7%. The drug’s safety profile was similar to placebo, with no major safety concerns reported and low rates of discontinuation due to adverse effects.

Enlicitide Implications: What Does This Mean Clinically?

These reductions are substantial, suggesting oral enlicitide could:

• Improve adherence since it eliminates the need for injections
• Increase access, particularly in resource-limited areas
• Provide an alternative for patients intolerant or resistant to statins

In India, where ASCVD prevalence is high and expensive therapies are less accessible, this pill could provide a practical, scalable option alongside diet, exercise, and current statin or ezetimibe treatments.

Enlicitide Caveats: Unanswered Questions To Be Mindful Of

Despite the promising LDL-C reductions, several key issues remain:

• Cardiovascular outcomes: It is not yet confirmed whether enlicitide lowers heart attacks, strokes, or mortality. Current data focus on cholesterol reduction, not clinical endpoints.
• Long-term safety: Data beyond 24 weeks and one year is limited.
• Approval and cost: Enlicitide is still investigational and not available for regular use. Regulatory approvals, like FDA evaluation, will review full data. Its real-world adoption in India will depend on cost and accessibility.
• Patient selection and combination therapy: How enlicitide will be integrated with existing statins, ezetimibe, and lifestyle interventions is still under review. Guidelines may require updating.
• Sub-group efficacy: Will results apply across different ethnicities, comorbidities, and specifically the Indian population? Local data will be important.

The investigational oral pill enlicitide could represent a major advance in cholesterol management. For patients whose LDL-C remains high despite statins, or who cannot tolerate injections, it offers a potent and convenient alternative. Yet, medicine requires caution.

According to NHS advice, people who use gabapentin may face rare emergencies linked to the medicine. Although it is not officially classed as a painkiller, doctors often prescribe it for nerve pain that follows an injury. It is also used for discomfort caused by shingles or diabetes. The medicine works by interrupting pain signals that move between the brain and spinal cord. Gabapentin is also a common treatment for epilepsy and falls under the group of anticonvulsant drugs. Most people take it as capsules, tablets, or a liquid, usually three times a day.

NHS information notes that the majority of users do not face any side effects. Those who do usually notice only mild and short-lived symptoms.

What Is Gabapentin?

Gabapentin is a prescription drug that belongs to a group of medicines called anticonvulsants. Doctors usually give it to people who have nerve pain or to help manage certain types of seizures in epilepsy. It is sold under names like Neurontin, Gralise, and Horizant, along with widely used generic versions.

What Is Gabapentin Approved For?

Gabapentin is prescribed for a few main purposes:

• It helps prevent and control partial seizures. Adults and children aged three and older who experience partial seizures can take it as part of their treatment plan.
• It also eases nerve pain that can appear after a bout of shingles in adults. Shingles develops years after a person has had chickenpox. The chickenpox virus stays quiet in the dorsal root ganglion, a section of the spinal nerve. In some people, usually during times of heightened stress, the dormant virus becomes active again and causes the painful shingles rash. When the rash settles but the nerve pain remains, the condition is known as postherpetic neuralgia.
• Gabapentin is also approved for people who have moderate to severe primary restless legs syndrome.
• Neurontin and Gralise, the branded forms of gabapentin, are licensed for treating partial seizures and postherpetic neuralgia. Horizant, another branded version called gabapentin enacarbil, is approved for restless legs syndrome and postherpetic neuralgia.

Side Effects Of Gabapentin

There are times when gabapentin may lead to serious reactions that need emergency attention. Mild effects can include an upset stomach, dry mouth, weight gain, or slight memory troubles.

More concerning reactions may involve thoughts of self-harm, unusual muscle pain or weakness, or seeing or hearing things that are not there. Even then, NHS guidance states that these usually require an urgent call to a doctor or 111 rather than ambulance help.

When You Should Call 999 While Taking Gabapentin

Like many medicines, gabapentin can trigger a severe allergic reaction known as anaphylaxis. This can cause several symptoms, such as swelling in the throat or difficulty breathing. The NHS advises calling 999 if you are taking gabapentin and experience any of the following:

• Sudden swelling of the lips, mouth, tongue, or throat
• Fainting and the person cannot be woken
• Lips, skin, or tongue turning blue, pale, or grey
• Trouble breathing or unusually fast breathing
• A tight sensation in the throat or difficulty swallowing
