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?

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.

Women who are conflicted while choosing between an injectable contraceptive, a copper intrauterine device (IUD) or a hormonal implant may not need to worry about its impact on human papillomavirus (HPV).

What Is Human Papillomavirus (HPV)?

HPV is one of the most common sexually transmitted infections worldwide. While many HPV infections go away on their own without causing problems, some high-risk types can persist and increase the risk of cervical cancer in the long run.

Before this study, scientists debated whether hormonal contraceptives could affect a woman's immune response, making it easier to contract HPV or harder for the body to clear the infection.

Birth Control Choice May Not Influence HPV Risk

According to a new study published in The Lancet Regional Health – Africa, your choice of contraception may not have an impact on the risk of contracting HPV.

Researchers found that women using a commonly used injectable contraceptive known as depot medroxyprogesterone acetate (DMPA-IM), copper IUDs, and levonorgestrel implants had similar chances of contracting HPV and clearing existing infections.

The researchers examined data from women who participated in the large ECHO (Evidence for Contraceptive Options and HIV Outcomes) clinical trial. Participants were randomly assigned to one of three contraceptive methods:

• Depot medroxyprogesterone acetate (DMPA-IM) injectable contraceptive

• Copper IUD

• Levonorgestrel implant

They then compared how often women acquired HPV during the study and how often those who already had HPV were able to clear the infection naturally. The analysis found no meaningful differences between the three contraceptive methods.

Women using the injectable contraceptive were no more likely to acquire HPV than those using a copper IUD or a hormonal implant. Similarly, women across all three groups cleared HPV infections at comparable rates.

Earlier studies finding the link between hormonal contraceptives and HPV have reported mixed results. Some suggested that hormonal birth control might increase the risk of HPV infection or make infections last longer, while others found no clear outcomes.

This new research provides stronger evidence because it is based on a randomized clinical trial. The findings suggest that the type of contraceptive a woman chooses is unlikely to have an impact on her risk of getting HPV or her body's ability to clear the infection.

Women Can Take Control Of Their Contraceptive Choice

The study allows women to choose between these commonly used contraceptive methods based on factors such as effectiveness, convenience, side effects, and personal preference, rather than concerns about HPV risk.

However, experts stress that no contraceptive method protects against sexually transmitted infections, including HPV. Using condoms can help reduce the risk of HPV and other STIs.

The human papillomavirus causes more than 200 known infections. While some types lead to benign skin warts, others are responsible for severe health threats, such as cervical, throat, anal, and penile cancers. The HPV vaccine provides strong protection against the most lethal strains, avoiding long-term health complications.

The HPV vaccine helps the immune system recognize and fight off high-risk strains of the virus before they cause harm. It protects against:

• Genital warts

• Cervical cancer

• Vaginal, vulvar, anal, and penile cancers

• Mouth, throat, head, and neck cancers linked to HPV

Experts also stress that HPV vaccination and regular cervical cancer screening remain the most effective ways to prevent cervical cancer and detect abnormal changes early.

People in the UK can, from today, access the Wegovy weight loss pill through pharmacies with a doctor's prescription. It is the first oral glucagon-like peptide-1 (GLP-1) medicine approved in the UK for weight loss.

The Medicines and Healthcare products Regulatory Agency (MHRA) approved the tablet on June 11, marking the first oral GLP-1 treatment available in the country for obesity management.

"Having met the MHRA's rigorous standards of safety, quality and effectiveness, the semaglutide tablet has been approved in the UK for weight loss and weight management," Julian Beach, Executive Director of Healthcare Quality and Access at the MHRA, said in a statement.

"As with all GLP-1 receptor agonists, this is a prescription-only medication," Beach added.

Novo Nordisk called it an "important milestone for obesity care in the UK".

"For the first time, people living with obesity have access to a GLP-1 treatment in a daily pill, allowing them the choice and flexibility of oral treatment to support their long-term weight management," said Sebnem Avsar Tuna, General Manager at Novo Nordisk UK.

The semaglutide (Wegovy) tablet can be prescribed alongside a reduced-calorie diet and increased physical activity for adults who:

• Have obesity (BMI of 30 or above), or
• Are overweight (BMI between 27 and 30) and have at least one weight-related comorbidity.

Wegovy Weight Loss Pill Dosage

Patients must begin with the lowest dose of 1.5 mg once daily, which can be gradually increased to:

• 4 mg
• 9 mg
• 25 mg

People currently taking 2.4 mg weekly semaglutide injections privately can switch directly to 25 mg semaglutide tablets once daily.

According to the MHRA, the tablet should be:

• Taken whole on an empty stomach after fasting for at least eight hours.
• Swallowed with a small sip of water.
• Followed by no food or drink for at least 30 minutes, as eating or drinking sooner reduces the drug's absorption.

Patients are advised to carefully follow the instructions in the Patient Information Leaflet.

How Does Wegovy Work?

Semaglutide is a GLP-1 receptor agonist that mimics the action of the naturally occurring GLP-1 hormone released after eating.

It acts on areas of the brain that regulate appetite by:

• Helping people feel fuller for longer.
• Reducing hunger.
• Decreasing food cravings.

Wegovy: Is It Available On The NHS?

Not yet. Although the medicine has received MHRA approval, it is not currently available through the NHS.

The MHRA said NHS availability will depend on the usual evaluation process by the National Institute for Health and Care Excellence (NICE).

NICE said Novo Nordisk has not yet formally approached it, but that it is in active discussions with the company, BBC reported.

Wegovy Weight Loss Pill: What Are The Side Effects?

The most commonly reported side effects are gastrointestinal and include:

• Nausea
• Diarrhea
• Constipation
• Vomiting

The MHRA said it will continue to monitor the medicine's safety and effectiveness. Anyone experiencing side effects should speak to their doctor, pharmacist, or nurse and report them through the MHRA Yellow Card scheme.

Pharmacies Expect High Demand

Community pharmacies say they are preparing for a surge in demand following the launch. The National Pharmacy Association (NPA) urged patients to obtain the medicine only from regulated pharmacies following a proper clinical consultation.

The Democratic Republic of the Congo (DRC) is battling one of its deadliest Ebola outbreaks in recent years. While it is driving innovation in medical science with new clinical trials and diagnostic tests, it is also a stark reminder of the urgency to contain the outbreak as soon as possible.

What Makes This Ebola Outbreak Deadlier?

According to the latest data, the death toll in DRC has now crossed 500 with at least 1,528 cases that are reported and confirmed.

While Ebola is not a new disease, the current outbreak stands apart because it is being caused by a rare strain of the virus, Bundibugyo.

Unlike previous outbreaks dominated by the Zaire strain of Ebola, the current epidemic, caused by the Bundibugyo virus, is a much less common species of the Ebola virus family.

The rarity of the strain has created unique scientific and emergency public health challenges, as there is currently no licensed vaccine designed to protect against Bundibugyo Ebola virus.

During outbreaks caused by the Zaire strain, vaccination became an important part of outbreak control. In the current epidemic, however, public health officials are being forced to rely heavily on rapid diagnosis, infection prevention, surveillance, and existing medical care.

Bundibugyo Ebola Virus: Latest Developments

WHO Clears First Diagnostic Test

In a major scientific breakthrough, the World Health Organization (WHO) recently added the first molecular diagnostic test for the Bundibugyo Ebola virus to its Emergency Use Listing (EUL).

The test detects the virus's genetic material in blood samples, enabling laboratories to confirm infections more quickly and accurately.

First Treatment Trial Underway

WHO and its partners have launched the first clinical trial specifically evaluating treatments for Bundibugyo Ebola virus disease.

Researchers are testing the experimental monoclonal antibody MBP134, the antiviral drug remdesivir, and a combination of both to determine whether they can improve survival.

About Bundibugyo Ebola Virus

The Bundibugyo virus was first identified in Uganda in 2007 and has caused only a few outbreaks since then. As infections have been relatively uncommon compared to the Zaire strain, researchers have had limited opportunities to develop vaccines, treatments and diagnostic tests.

Due to this, healthcare workers have been compelled to rely primarily on rapid isolation of patients, intensive supportive care, contact tracing, and strict infection prevention measures to slow transmission.

Currently, Eastern DRC is the hotspot for the Bundibugyo Ebola outbreak, where conflict, population displacement, skepticism, and insecurity have made it difficult for health workers to reach affected locations.

Here, access to healthcare still remains uneven in many areas. Additionally, movement of people across districts and states in the country can accelerate the spread of infection significantly.

As scientists race to validate new diagnostics and evaluate experimental treatments, the Bundibugyo outbreak is becoming more than a public health emergency. It is also serving as a critical test of how quickly the global health community can develop and deploy new tools against an emerging infectious disease.
