What are antibiotics? Why should there be assistance for their usage?

Antibiotics have been an effective means of treatment in modern medicine since the 1940s. They provide defense against various diseases and infections and even save lives. However, there are many instances where antibiotics become ineffective and can cause harm to the body instead of healing it. New resistance mechanisms are emerging and spreading globally threatening our ability to treat common infectious diseases we encounter on a daily basis.

A growing list of infections - such as pneumonia, tuberculosis, blood poisoning, gonorrhea, and foodborne diseases - are becoming harder, and sometimes impossible, to treat as antibiotics become less effective. In that case, such infections can no longer be treated by first-line antibiotics, therefore more expensive medicines must be used. However, such a catalyst will do more damage than it will be of help since not everyone can afford medication nor get prescriptions from doctors and antibiotics were the way to tackle those daily diseases encountered.

Consequently, many researchers believe that this issue of antibiotics becoming less effective is due to overprescription and the urge to take antibiotics without professional assistance, especially in middle and low-income countries.

“We know many of these antibiotics are being used inappropriately,” said Eili Klein, a professor at John Hopkins University Department of Emergency Medicine. Klein also added that despite all of what’s been previously said, there is still no comprehensive body that is in charge of measuring exactly where or how.

So what if there’s an over-usage of antibiotics?

One would typically ask themselves such a question, I mean commonly, if you increase the dose of some sort of medicine, that medicine becomes more effective and helpful. Well, let’s toss that theory away - or shall I say myth - because it’s completely untrue, at least it is in the case of antibiotics. The major issue of antibiotics’ over-usage is that the bacteria - that was supposed to be killed - can develop a resistance against the antibiotic being used which can lead to severe issues in the future if not properly treated. Antibiotics have no effect on illnesses such as the common cold, but many individuals still believe that antibiotics can help treat the common cold. This misconception is dangerous. Not only can overuse or misuse of antibiotics lead to drug resistance, but it can also lead to serious health consequences such as clostridium difficile infections - also called c. diff.  which causes severe diarrhea that can lead to colon damage and death.

In order to avoid such painful risky situations, first, you should acknowledge what antibiotics are really for and what they actually treat. Antibiotics treat certain infections caused by bacteria, NOT viruses. Some of the infections - caused by bacteria -  antibiotics treat are:

  • Bloodstream infections
  • Skin abscess/impetigo
  • Bacterial pneumonia
  • Urinary tract infections
  • Streptococcal pharyngitis
  • Middle ear infections

Some of the infections - caused by viruses - antibiotics do NOT treat are:

  • Colds infections
  • Sore throats 
  • Upper respiratory infections 
  • Influenza or “the flu”

These infections above are caused by viruses which antibiotics can not kill nor stop from spreading. For instance, the only treatment for colds is rest and time.

What are the possible side effects of improper antibiotics use?

Improper antibiotics use has many definitions, it could mean taking an unnecessarily big dose, using the wrong antibiotics, taking them when they are not needed, and even often misinterpreting what this antibiotic is really for. Such misconceptions can really decrease the options for treatment of an option which is really nurturing the possible global issue in the healthcare sector which is called “post-antibiotic apocalypse” and the end of what we call modern medicine. Moreover, as mentioned before, misuse of antibiotics can cause a bacterial resistance - or antibiotic resistance - even to the strongest antibiotics to ever exist. The Centers for Disease and Control and Prevention (CDC) calls it “one of the world’s most pressing public health problems.”

What can one do to avoid the risk of bacterial resistance and antibiotic overuse?

There are many ways one can prevent such health problems and stay on the safe side, such methods should be established by parents first in order to teach their child whilst protecting them, and some of these ways are:

  • Ask the doctor if the patient’s illness is bacterial or viral. Discuss the risks and benefits of antibiotics. If it’s a virus, ask for ways to fight the symptoms and do NOT pressure your doctor into prescribing antibiotics.
  • Let milder illnesses run their course (this helps prevent germs from becoming resistant to antibiotics). 
  • Take antibiotics  for the full amount of time and completely like prescribed by the doctor.
  • Do not take antibiotics longer than prescribed.
  • Antibiotics prescribed for an adult family member should not be necessarily given to children even if both parties have the same symptoms. Different bodies react differently.

The chart below shows examples of when one does and does not need antibiotics. Always keep in mind that antibiotics treat bacteria-caused infections and not virus-caused ones!

TL;DR Science: Oncogenes

Perhaps you may have heard someone say at one point “I am at risk for ___ cancer, so I have to take extra precautions…”. Or, you may have heard the claim that “Sunscreen can reduce your risk of getting skin cancer”. Two questions consequently arise: first, how do we actually know of cancer risk; second, what does it mean to be at risk? To start we have to look at our cells’ DNA and what can happen if it becomes mutated.

TL;DR Color Blindness

Have you ever wondered why traffic lights are always in the same order: red at the left (or top), yellow at the center, and green at the right/bottom? It may surprise you that this standardization was made in fact to accommodate for color blind people. Check out this article to see how color blindness is caused!

TL;DR Science: Reducing Greenhouse Gas Emissions

Greenhouse gases have long been a topic of concern, and it is imperative that we address the ongoing climate crisis before it is too late. Before discussing how we can reduce greenhouse gas emissions, it is important to understand the science behind the greenhouse effect and each of the greenhouse gases themselves. You can learn more about that in parts one and two of this 3-part series on the greenhouse effect and greenhouse gases!

TL;DR Science: Bariatric Surgery

More than 1-in-3 adults in the World are obese, about 39%. The average weight of the US adult has a BMI* of 26.5-26.6 depending on sex which is higher than the healthy BMI for adults of 25. It is painfully evident that obesity is an epidemic in the United States and across other developed countries. In order to reduce the amount of food consumed, surgeons can perform different kinds of procedures to reduce the size of the stomach or bypass it all together.
