Caffeine is found in various sources, such as coffee, flu medication, and chocolate. Caffeine is the most often used psychoactive drug globally.

It is frequently mentioned in the press for its potential effects on health. Advocates highlight its benefits,

while critics criticize its risks. Who is correct? Both and neither, as it happens.

Cardiovascular health
Research indicates that caffeine may have positive effects on our cardiovascular health. Researchers discovered a correlation between increased coffee consumption and a reduced likelihood of heart failure in an examination of three extensive heart disease studies. Drinking decaffeinated coffee did not produce the same result, suggesting that the impact may be attributed to caffeine. However, additional research is needed to confirm this hypothesis.

Researchers have shown short-term cardiovascular effects associated with the consumption of highly caffeinated beverages. Consuming around one liter of fluid with 320 milligrams of caffeine, equivalent to four 250-milliliter cans of Red Bull, can lead to transient instances of elevated blood pressure and heart palpitations.

It is a noticeable phenomenon when energy drinks are mixed with alcohol; thus, it could be wise to consume Jägerbombs in moderation.

Metabolic health

A recent study revealed that individuals with elevated blood caffeine levels may have a reduced likelihood of developing obesity and type 2 diabetes. These people possessed genetic variations in two genes linked to caffeine metabolism, resulting in a delayed breakdown of the molecule and leading to elevated levels of caffeine in their blood.

However, due to the assumption that weight loss affected caffeine’s effects by 50%, this study had some limitations. The study predominantly focused on individuals of European descent; hence, the results may not be universally applicable. Additional research is required to investigate whether increasing coffee consumption could potentially decrease the risk of these two illnesses.

Psychological well-being

Caffeine is a stimulant that many people consume in the form of coffee or energy drinks to increase energy levels and improve mood, particularly in the early morning or mid-afternoon. How does it accomplish this? Neurologist Dr. Nicole Clark, as part of the American Medical Association’s What Doctors Wish Patients KnewTM series, stated that caffeine boosts dopamine, a brain chemical involved in pleasure, motivation, and learning.

Conversely, if you have prior experience with problems such as panic disorder and anxiety, current studies indicate that caffeine could exacerbate your mood. A 2022 meta-analysis discovered that ingesting approximately five cups of coffee equivalent in caffeine caused anxiety in patients with panic disorder (PD) and in healthy individuals. However, individuals with PD were more likely to experience a panic attack.

Fetal well-being
Caffeine can pass through the placenta and into the circulation of a developing fetus. Studies have shown that consuming over 300 milligrams daily may lead to a higher risk of low birth weight, and above 350 milligrams can be connected to pregnancy loss.

Many healthcare organization rules allow pregnant individuals to use caffeine but recommend a daily limit of 200 mg. A 2020 study found that increasing data indicates that there is no safe amount of caffeine that may be used during pregnancy.

Athletic performance
Caffeine supplementation is a common practice in fitness and sports performance, where it is frequently included in pre-workout powders in different doses. Studies indicate that creatine supplementation can enhance athletic performance. However, much of the research has focused on male athletes, and sports nutrition organizations have incorporated it into their standards.

A meta-analysis of studies on female team sports athletes revealed that caffeine administration effectively enhanced handgrip strength and countermovement jump performance but did not show significant improvements in agility, squat jumps, or repeated sprint ability. It was determined that further research was necessary before generalizing the present concepts concerning caffeine.

There have been suggestions that coffee may enhance performance in certain activities, but the extent to which this benefit is specifically attributed to caffeine remains uncertain.

The general overview
Individual factors like metabolic rate, potential drug interactions, and consumption levels most likely determine the effects of caffeine, whether they are positive or negative.

Caffeine is a drug, and caffeine toxicity or overdose, although rare, can be lethal. It is advisable to be prudent, especially when dealing with caffeine supplements.

The Food and Drug Administration (FDA) provides guidance on determining the threshold for excessive caffeine consumption. Possible symptoms:

  • Insomnia
  • Nausea and disturbed stomach
  • Headache
  • Feelings of nervousness and anxiety
  • Experiencing discontent

It is advisable to reduce caffeine intake gradually if you are trying to cut back. Cold turkey withdrawal from caffeine may not be as risky as with other substances, but it can still result in uncomfortable symptoms such as headaches and exhaustion. It is advisable not to abruptly stop consuming coffee to avoid these negative effects.

A recently identified strain of deadly fungus poses a significant risk to public health

Researchers have recently discovered a new group of Candida auris, a potentially dangerous pathogen. The finding increases the total number of identified clades of the fungus, which is a newly emerging superbug resistant to multiple drugs, to six.

Candida auris is a strain of yeast that has the potential to cause serious illness and is frequently impervious to antifungal drugs. While individuals who are in good health generally do not fall ill, the transmission of the disease is highly prevalent within medical institutions and poses a significant risk to individuals with compromised immune systems. The yeast can induce a variety of conditions ranging from superficial infections of the skin to more severe and life-threatening illnesses, such as bloodstream infections. Due to its high level of resistance to multiple drugs, treating it can be challenging, and in some cases, even impossible.

The authors state that the pathogen is a significant global public health threat due to its widespread distribution, resistance to multiple drugs, high ability to spread, tendency to cause outbreaks, and high mortality rate. Although infections are still relatively uncommon, there has been a significant increase in cases in recent years.

Previously, the fungus had been categorized into five distinct clades, each located in different geographic regions: South Asia, East Asia, Africa, South America, and Iran.

In April 2023, doctors from the Singapore General Hospital identified a patient carrying a unique strain of C. auris as part of a routine screening program, adding it as the most recent clade to be discovered. Typically, these cases arise from individuals who have recently traveled, but this particular patient had not traveled outside the country for a period of two years, which raised some concerns.

Upon conducting a genetic analysis of the strain, the researchers determined that it did not align with any of the five known clades of the fungus. Therefore, it can be concluded that the strain belongs to a previously unidentified, sixth clade. Subsequently, they conducted tests on strains obtained from previous patients and identified two additional isolates of this particular group of C. auris in Singapore, as well as another isolate in Bangladesh.

The extent of the new clade’s prevalence and its potential to cause invasive infections and outbreaks remains uncertain at present. However, the researchers emphasize the importance of promptly identifying and controlling it in order to safeguard patient well-being.

“The ramifications of this breakthrough transcend the confines of the laboratory.” “Given the recent discovery of the sixth Candida auris clade, it is imperative to enhance surveillance capability or create new methods to strengthen existing surveillance strategies. This will enable health care facilities to closely monitor its emergence and effectively control its spread,” stated Dr. Karrie Ko, co-first author of the study.

Fortunately, the cases described in the study remained vulnerable to all antifungals that were tested. This should alleviate concerns about a pandemic similar to the one depicted in The Last Of Us. However, it is evident that the threat of C. auris is persistent. Therefore, additional efforts are required to identify new strains, monitor their spread, and control any negative clinical consequences.

The research is published in The Lancet Microbe journal.

What makes your chest hurt when something makes you jump?

Have you ever been scared so badly that you grabbed your chest? You feel like someone or something just zapped you behind the sternum. As you rest, you lean against the wall and think about why your friend is such a jerk and why you can feel it in your chest whenever you get scared.

People often use words like “heart-stopping” when they write fiction about fear, but the science of fear tells us that this isn’t what’s happening because it wouldn’t make sense. Our bodies are getting ready to deal with an impending threat when we’re scared, and going into cardiac arrest wouldn’t help us get very far if a lion was after us.

What do we do when we’re scared?
The sympathetic nervous system is what gets you excited when something makes you jump. It’s a tool inside our bodies that releases hormones and changes the way our bodies work to get us ready for the fight-or-flight response.

One important part is adrenaline, which is also known as epinephrine. The adrenal glands squeeze it out into the blood. The heart starts beating faster, sending more blood to your muscles and organs right away. Because they need all the oxygen they can get if they want to get away from a dangerous animal.

How do you feel when you go for a run?
Anyone who has ever used an EpiPen knows how bad it is to feel a sudden rush of adrenaline. It’s a stress hormone that makes you feel nervous and anxious, like you would before doing a bungee jump. Getting a rush when you think about a traumatic event from the past can be a sign of PTSD.

A medicine called adrenaline is used because it can help people who are having a medical emergency. If you have anaphylaxis from an allergen like peanuts, this can help because it can open your airway. Because it changes the strength and speed of heartbeats, it is also sometimes used to help people who are having a cardiac arrest.

When your adrenaline level goes up quickly, you may feel shaky, your heart beat quickly, and your chest get tight. When you add in the fact that you’re more alert, you become very aware of the changes in your body. This is especially clear when you’re not in danger, like when your partner surprised you at home when you thought you were alone.

When you’re scared, your sympathetic nervous system usually kicks in, which is normal. But, some heart conditions can get worse when you’re scared. Should anyone be having chest pain or ongoing discomfort, they should see a doctor. In the end, it is possible to be so scared that you die.

The Lacks family is suing again over her “stolen” cells

The family of Henrietta Lacks has filed a new lawsuit against two sizable drug companies for using her genetic material without her consent.
In the US District Court for the District of Maryland, Lacks’ living relatives are suing Novartis Pharmaceuticals Corporation, Novartis Gene Therapies, Inc., Viatris, Inc., and its subsidiary, Mylan Pharmaceuticals. They say the companies have used the “stolen” HeLa cell line to make hundreds of patents and have made a lot of money from it.

The suit wants the money made from using these cells to be “rightfully transferred” to Henrietta Lacks’s estate.

Novartis and Viatris chose to sell Henrietta Lacks’ living genetic material. Lacks was a black grandmother, community leader, and woman whose doctors took her tissue without her knowledge or permission, according to Chris Ayers, an attorney at Seeger Weiss LLP who is representing the Lacks family.
Ayers added, “We will keep looking for justice for Mrs. Lacks and her family.”

Henrietta Lacks died on October 4, 1951, from cervical cancer. She was 31 years old. Some of her cells are still alive today. A doctor at Johns Hopkins Hospital took a sample of her cervical cells without her knowledge just before she died. They were doing a cancer check. It was seen that her cells kept multiplying quickly, even after most of the cells in other samples would have died without their host.

Because scientists saw the potential, they found that these cells could be a cheap and easy way to help researchers do more research. The “HeLa immortal cell line” is what scientists call these cells, and they are very useful for biomedical research.

Over 75,000 scientific studies around the world have used these cells, which amount to about 55 million tons. They have been very important in making progress in areas like polio vaccines, cancer treatments, HIV/AIDS treatments, and much more.

All of this was done, though, without Lacks’ knowledge or permission. For many years, her family also didn’t know that the cells were being used for business.
Selling HeLa cells for money brings up important issues in medical ethics and genetics. As a black woman living in America in the 1950s, Lacks’ case shows how medical racism still affects minorities who aren’t getting enough help.

Even though a lot of people know about these problems, HeLa cells are still used in medical research for profit, which makes some companies a lot of money.
“Now that everyone knows Henrietta Lacks’ story, it’s shocking, but not surprising, that drug companies like Novartis and Viatris are still making money off of the deeply unethical origins of HeLa cells and the disturbing history of medical racism,” said Chris Seeger, another lawyer for the family.

A historic deal was made by Lacks’ family in 2023 after they sued Thermo Fisher Scientific, Inc., another biotech company, in the US District Court for the District of Baltimore. During that time, the lawyers said that the settlement was only the beginning and that there could be many more lawsuits about the use of HeLa cells.
