Clean Water Crisis

Some people view a glass as half full, and others see it as half empty, but sometimes the water is just too dirty for it to matter.  Flint, a city nestled between three of the Great Lakes in Michigan, is facing a critical water crisis causing serious concern amongst the residents. In a city that already has a 13.6 year lower life expectancy than the rest of the Michigan state,  solutions and action are needed immediately.

A water sample study, carried out by Virginia Tech, revealed alarmingly high levels of lead, with readings ranging from 200 parts per billion (ppb) to 13,200 ppb. To understand the magnitude of these findings, let’s take a look at the recommendations and effects of lead.
According to the Guidelines for Canadian Drinking Water Quality, the maximum acceptable concentration (MAC) of lead is 10 ppb, while the Environmental Protection Agency has a lead concentration regulation of zero in drinking water, as there is no safe lead consumption level. Therefore, Flint’s water samples exceeded the MAC by 20 to over 1,300 times!

As a result, the citizens of Flint have been exposed to dangerously high levels of lead, which cause toxicity and a long list of health problems. No body system is spared from lead poisoning, as severe damage to the kidneys, joints, bone marrow, and cardiovascular system is debilitating and permanent. Additionally, the digestive and urinary tract, brain and nervous system, and reproductive organs are also highly susceptible to irreversible damage.

Perhaps even more concerning, is the vulnerability of a child’s body to lead ingestion. Since lead tricks the body into thinking it is an essential element (such as calcium, for example), a child’s absorption is four to five times higher than that of an adult. In fact, a study published in December, 2015, found the levels of lead in children’s blood to have doubled in concentration compared to the levels recorded in 2013 in Flint residents under the age of five. In addition to the effects previously mentioned, a child can also suffer from delays and disturbances in development, both physically and mentally, such as a low IQ.

Evidently, the water in Flint is not suitable for drinking, and according to pediatricians involved in the care of patients in this area, only time will tell the full extent and consequences of this massive lead contamination. Ensuring that successful, cost-effective, and easily-implemented water treatment systems are available and functioning at acceptable standards is clearly a crucial aspect to the well-being and health of a community.

Hospitals: More Dangerous Than You Think?

If someone suffered a heart attack or was involved in a car accident, the first place we would turn to is the nearest hospital, right? It happens almost every day; someone is carried into the ER on a stretcher and leaves smiling, walking on their own two feet. Generally, hospitals are perceived to be a safe place of medical assistance, treatment, and recovery, however, there is growing data to suggest that a stay in the hospital may actually come with risk.

Health care-associated infections (HAI), also called nosocomial infections (from the Greek word nosokomeíon, meaning hospital), are classified as infections that occur during a hospital admission and up to 3 days after discharge. They are a growing cause of lengthened hospital stays, medical complications, and even death in patients. In fact, it is estimated that these infections rack up a cost of one billion pounds for England’s National Health Service and over $35 billion for U.S. hospitals.

In 2011, the United States had almost 722,000 cases of HAI, ranging from surgical site infections to pneumonia. The Canadian Nosocomial Infection Surveillance Program also found an increase in the incidence of a specific bacterium, called C. difficile, from around 42 cases per 100,000 in 1992 to 160 per 100,000 in 2003. Additionally, the severity and reoccurrence also spiked, with more severe outcomes recorded, including perforated large intestines, shock, and death.

A common misconception is that only the elderly are at risk for HAI due to their weaker state of health. This is untrue, as studies find increasing numbers of these infections in children’s hospitals, maternity wards, and in the young adult population. A study published in 2014 found a more than triple increase in incidence of flesh eating disease, known as necrotizing fasciitis, in pregnant women that were admitted to hospital for delivery over the past decade. Children also experience a high prevalence of HAI, with the highest percentages recorded in intensive care (19%) and transplant units (27%).

So what can be done?
Unsurprisingly, poor hand washing has been attributed to 40% of infection transfers in hospitals, thus focusing on improving hand hygiene habits can have a positive impact. Increasing compliance of wearing protective accessories including gloves, masks, and aprons is also critical. As well, creating a system that immediately isolates patients who have contracted a severe infection is key to prevent further spreading.
Careful attention to sanitation must also be emphasized, as it was found that an antibiotic-resistant bacteria that attacks the intestinal tract can also be transferred between patients through the use of  thermometers.

The issue of HAI is a global problem, however it is not all doom and gloom when it comes to the future of patients’ well-being. Much research is currently underway to find new methods to decrease the prevalence. Take a look at the video below from the Mayo Clinic, where they tested the effectiveness of UV light disinfection. They found an impressive 30% decline in C. difficile infection in the UV-treated rooms!
