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.

Shigella infection, commonly known as shigellosis, has claimed a 4-year-old's life in Kerala. According to reports from the authorities, three children were admitted to Kozhikode Medical College Hospital with this infection. Though two of them recovered and were discharged, a four-year-old girl, Nila, succumbed to the disease. She was from Thalakkulathur.

After this first fatality due to shigella, the state's health minister K Muraleedharan, addressed a press conference and said that shigella is a bacterial infection that mainly affects the intestines and causes symptoms such as diarrhoea, fever, and abdominal pain.

Muraleedharan said, "The disease mainly spreads through contaminated food and water. Strict hygiene practices are essential to prevent its spread." Then added, "Around 123 cases were reported in Alappuzha and Pathanamthitta districts last week."

The health minister also confirmed that Shigella was not the reason behind gastrointestinal illness among students in Wayanad. Around 164 students from educational institutions in the Sulthan Bathery region reportedly developed symptoms including vomiting and diarrhoea. Initially, there were concerns over them also being infected by Shigella, but preliminary tests showed that they were not infected.

Though he also added that a medical team from Kozhikode Medical College was dispatched to the area, and will collect samples for testing there. He said, "Initial reports suggest that the cases are not related to Shigella, but further testing is underway, and a final report is awaited."

The local authorities have also issued strict instructions on preventive measures. The health department has ordered the food safety department to conduct inspections, and hotels and eateries were instructed to maintain hygiene and ensure the provision of safe drinking water to customers.

The health minister stressed that the local self-government must take proactive measures to ensure public health.

What Is Shigella?

Shigella is a highly infectious bacterium that causes gastrointestinal illness, commonly known as shigellosis. Its symptoms often include diarrhea, fever, and stomach cramps, which can range from mild to severe. Estimates suggest around 188 million cases occur each year, leading to over 1.6 lakh deaths due to Shigella throughout the world.

The infection spreads easily through contact with contaminated food, water, or surfaces, and through person-to-person transmission. Though it is a very infectious bacterium, certain groups are more vulnerable to infection. These groups include young children and people with weakened immunity. Notably, exposure risk increases in environments where hygiene practices may vary.

How To Prevent Shigellosis?

Early recognition and treatment with appropriate antibiotics is crucial to protect oneself from this disease. Notably, ORS can help prevent dehydration, while Zinc tablets can enhance recovery. Other measures to prevent the spread include washing hands with soap and water, especially before touching food, and after using the toilet, and maintaining hygiene. Controlling flies is also very important to prevent the disease.

Nigeria is witnessing an outbreak of cholera, and to curb the spread of the disease, the police there have ordered sanitation measures in the northeastern state of Borno. According to the local media and authorities, about 39 people have died due to the waterborne disease. Local authorities have also reported at least 4,204 cases of infection.

According to the local health authorities, the outbreak is spreading in the Borno capital, Maiduguri, and the surrounding Jere district. The state police commissioner "has directed the full enforcement of the monthly environmental sanitation exercise." The statement added, "Residents are therefore urged to actively participate in the exercise by cleaning their homes, business premises, drainage channels, and surrounding environments."

He added, "To ensure compliance, police personnel and other relevant stakeholders will be deployed to strategic locations across the state during the sanitation period."

The nation is very cautious about the outbreak and has taken several steps to contain the disease as much as possible. The state government has set dedicated treatment centers for public convenience. Notably, cholera is spread by bacteria-tainted water and food, which can easily cause dehydration and diarrhoea.

The advent of modern sewerage systems has eradicated diseases throughout the modern world. Though war, conflict, and social unrest in nations like Nigeria and Sudan result in these unfortunate outbreaks, which take thousands of lives and affect many families.

As Ebola is spreading in African nations of the Democratic Republic of the Congo (DRC) and Uganda, another breakout of Cholera in Nigeria is showing the vulnerabilities of how rampant it is in Africa.

What Is Cholera?

According to the Centers for Disease Control and Prevention (CDC), it is caused by the bacterium Vibrio cholerae. This can be transmitted through drinking water or eating food that contains the bacteria. While most people who get cholera don't get sick, it can cause life-threatening diarrhea and vomiting.

CDC notes that each year, 1.3 to 4 million people around the world get cholera. Among them, 21,000 to 143,000 people die.

What Are The Common Symptoms?

The common symptoms include:

• watery diarrhea
• vomiting
• leg cramps
• losing body fluids
• dehydration and shock

Usually, people develop symptoms within 1 to 10 days of consuming the bacteria.

Who Is At More Risk?

People who live in areas with unsafe drinking water, poor sanitation, and inadequate hygiene are at the highest risk of getting cholera. The disease can spread quickly in areas where sewage and drinking water are not adequately treated. It can also live in brackish water, which is slightly salty, or in coastal water. Thus, eating raw shellfish can also cause cholera.

COVID-19, a name that can trigger a plethora of bad memories and constant fear, a time of solitude and captivity. Though now a breakthrough in medical science connected with coronavirus is giving hope to the possible prevention of Ebola. The universal vaccine was designed entirely by artificial intelligence (AI), and more importantly, it was successful.

It was the first time an AI-designed vaccine has completed a human clinical trial. The results of the trials were published in the Journal of Infection, and according to that report, phase one of the trial was observed by 39 healthy adult volunteers aged 18 to 50 and demonstrated a 100 pc safety profile.

The study stated that this vaccine was developed by the research team at the University of Cambridge and the company DIOSynVax, and they claimed that their vaccine has strong immune responses against various coronavirus strains.

And with this very crucial discovery in medical science, there is also a hope for designing a very effective vaccine for Ebola. Essentially, offering a proactive shield against a disease that continues to pose a significant global public health risk.

How Will This Breakthrough Contribute To The Development Of An Ebola Vaccine?

The vaccines that are traditional often tend to be reactive in nature, which means they can only work on a particular strain of a virus, and as a result, when the virus mutates and evolves, it becomes obsolete.

Artificial intelligence or machine learning can make a big difference in this aspect as it scans the genetic sequences of an entire family of viruses. The development of a universal COVID vaccine followed the same process. The AI pointed out the core features common to all of them, including strains that haven't even crossed over to humans yet, and after that, it has designed the new vaccine.

Though this very vaccine will not directly work on Ebola, the same process and technology can be used to create a similar vaccine in record time for Ebola as well. As the situation of the disease worsens by the day, it has crossed 500 cases.

As of Saturday, the Democratic Republic of the Congo (DRC) reported that its total number of Ebola cases had increased to 488 from 452 cases and caused 86 deaths. Its neighbor, Uganda, also has reported 19 cases.

This time, the Ebola outbreak has caused most harm to the Democratic Republic of the Congo (DRC), and during this mayhem, its neighboring nation, Uganda, which is also fighting to contain the disease as it is also seeing a surge in cases, has completely closed off its western border with DRC.

The World Health Organization (WHO) has declared the outbreak an international public health emergency, and the Centers for Disease Control and Prevention (CDC) warned that the Ebola outbreak of this time could swell to become the largest Ebola epidemic in history.
