Sharing the science behind health, disease, and wellness

Asthma: A Multifactorial Disease

Nathalie Fuentes Ortiz's picture

Last semester, I did an internship at the Allergy, Asthma and Immunology Clinic of the Penn State Health Milton S. Hershey Medical Center, where we specialize in treating patients with chronic respiratory disease. Soon after starting my clinical rotation, I noticed the large number of visits from Puerto Ricans, especially women. Alarmed, I decided to investigate the reasons for this trend, and I went to the library to find more information about the subject. 

November: Diabetes Awareness Month

Yomarie Bernier-Casillas's picture

Did you know that diabetes is one of the leading causes of death in the world and of which there is no cure? Diabetes is a chronic disease that affects the body's ability to use the energy contained in food. As a result, blood sugar (glucose) levels increase, resulting in a chain of short and long-term adverse effects. Depending on the type of diabetes patients need insulin or pills to control it.

After consuming food, our body transforms it into glucose and other nutrients that are absorbed by the blood. After eating, blood sugar level increases activating the pancreas that generates insulin and releases it into the bloodstream. In people with diabetes this does not happen because the body is not able to produce or react to insulin properly.

What you should know about leptospirosis

Due to the floods and lack of potable water caused by Hurricane Maria, leptospirosis has become a real public health concern for Puerto Rico. There are two suspected deaths due to leptospirosis and five cases with symptoms consistent with this disease so far.

Leptospirosis is caused by bacteria. Infection occurs when people come into contact with surfaces, soil, water, or food contaminated with urine from rats, mice, and other infected animals. One can get infected through the nose, mouth, eyes and open wounds on the skin. In addition, the disease can be contracted by drinking contaminated water. 

Why do we sleep?

We don’t often think about the purpose of sleep, yet we always feel better and more energized after a good night’s sleep. Studies have shown that we spend about one-third of our lives sleeping. Why is this so? There is no scientific consensus on the specific reason why we need sleep. While the question of exactly why we sleep is difficult to answer, sleep has many benefits. The effects of sleep deprivation can either manifest immediately, such as crashing your car due to excessive tiredness, or can build up with time and lead to chronic conditions. Research shows that sleep deficiency impairs your driving ability as much as being drunk. It is estimated that driver sleepiness is a factor in about 100,000 car accidents a year, and this may cause up to 1,500 deaths a year.

Heart disease affects the population of Puerto Rico in multiple ways: their physical and emotional health, quality of life, social and work relationships, and their wallet. February is heart health awareness month so we’ll take the opportunity to discuss some of the conditions that affect the heart and how we can prevent them.

Designer Drugs: A Lethal High

Roberto León Barriera's picture

Designer drugs are substances designed to mimic the effects of an existing drug. Their chemical structure is altered, which prevents them from appearing in standard drug screening tests. The idea behind these drugs is to create a new substance that is not classified as illegal, allowing dealers to sell it without breaking the law. As law enforcement officials get to know these drugs, they are classified as illegal.  Dealers then alter the structure again, repeating the cycle. In the United States, around 200-300 new designer drugs were identified between 2009-2014.  These drugs are often distributed in night clubs, parties, and raves. Aside from their many detrimental effects on the body, these drugs have an added danger and lethality.

Are you taking care of your bones?

Naiomy D Rios Arce's picture

Did you know that 5-10% of your bone is replaced every year? And that both females and males can develop osteoporosis?

Bone remodeling, the process by which new bone is formed and old bone is removed, is in charge of keeping your bones strong and healthy. This process is a continuous and tightly regulated cycle that requires interaction between two important cells, the bone forming cells (osteoblast) and bone degrading cells (osteoclast).
