Biomarkers Are Essential Medical Tools

A biomarker, in medicine, is anything that can be used to measure the health status of a person. A wide range of biomarkers is available to determine whether a person is healthy or sick. For instance, some are as simple as taking your pulse, body temperature, or measuring your blood pressure. Other biomarkers can be more complex, such as biological molecules used to identify genetic changes in cancer cells.

Norovirus The Viral Invader of the Gut

Dana is a 29 y/o marketing executive who woke up one winter morning “feeling sick.” She told her husband, “I feel tired, nauseated, and have mild stomach cramps.” It wasn’t long afterwards, she suddenly experienced the onset of vomiting, and diarrhea. Her husband encouraged her to drink liquids, but it only caused her to vomit more. The miserable morning led to dehydration, and by early afternoon she was receiving intravenous fluids in the Emergency Department of her local hospital.

FDA Puts on Hold All Infant RSV Trials Due to Safety Concerns

On December 12, 2024, the FDA in a briefing document “put on hold” all clinical trials of vaccines for respiratory syncytial virus (RSV) in infants. The FDA said it was notified by Moderna, in July 2024 that their findings from a clinical trial signaled safety concerns in infants. The two vaccine candidates were being evaluated during Phase 1 trial which primarily evaluates the drug’s, or vaccine’s safety and dose range.

Bird Flu H5N1, Asian Influenza: Wings of Worry — The Pandemic Threat of Bird Flu

Does Bird Flu have the potential to mutate into a more contagious and deadly version of itself just as SARS mutated into COVID19? Back in 2007, Gary Wong, and T Leung wrote, “Severe acute respiratory syndrome (SARS), and Avian influenza (bird flu) are the two newly emerged infections with pandemic potential that have arisen from Asia in the new millennium.” In 2020, COVID-19 fulfilled its pandemic potential, became a household word, and a deadly virus causing millions of deaths.

Untangling the “4 A’s” of Alzheimer’s Disease: What Are They?

Alzheimer’s Disease (AD) is a neurodegenerative disease that affects the neurons, the nerve cells in the brain. It’s a chronic, progressive disease that causes the loss of function, and structure of the nerve cells in the brain, resulting in the shrinkage of brain tissue with adverse emotional, mental, and physical effects. After the age of 60 years, the incidence of AD approximately doubles every five years.

Vaccinations .. “Stupendous Success” in Saving Lives: A Bedrock of Disease Prevention

Vaccinations have remarkably improved the survival, and health of individuals worldwide. A landmark study published in The Lancet in May 2024 analyzed 50 years of the Expanded Program on Immunization (EPI), and concluded that vaccinations have prevented an estimated 154 million deaths globally since 1974, with the majority occurring in children under five years old. They’ve cut infant mortality by 40 percent globally!

Alcohol and Cancer: The Myth That “Moderate” Alcohol Drinking is Healthy?

The number of older adults in the United states has grown significantly. Likewise, there has been a noticeable increase in drinking among senior citizens. Many of us have been under the impression that the moderate intake of alcoholic beverages has a positive health effect, in particular, on heart health. This notion has been debunked by a team of researchers who reviewed a large British study that followed 135,103 adults over a span of twelve years who were aged 60 and older.
