In the United States in 2010, over 1,500 pedestrians were estimated to be treated in emergency rooms for injuries related to using a cell phone while walking. Jack Nasar, from The Ohio State University (Ohio, USA), and colleagues used data from the National Electronic Injury Surveillance System, a database maintained by the U.S. Consumer Products Safety Commission (CPSC), which samples injury reports from 100 hospitals around the country. These reports are used to estimate total injury occurrences at emergency rooms across the country. The team examined data for seven years (from 2004 to 2010) involving injuries related to cell phone use for pedestrians in public areas (in other words, not at home). Findings showed that in 2004, an estimated 559 pedestrians were treated in emergency rooms for injuries received while using a cell phone. That number dropped to 256 in 2005, but has risen every year since then. The study found that young people aged 16 to 25 were most likely to be injured as distracted pedestrians, and most were hurt while talking rather than texting. Writing that: “Using a mobile phone while walking puts pedestrians at risk of accident, injury or death,” the study authors warn that: “Walking and talking or texting can be dangerous.”

Estimated to affect 125 million people worldwide, psoriasis is a chronic inflammatory condition affecting the immune system that commonly manifests in the form of thick, red, scaly patches on the skin.
Researchers from Harvard Medical School (Massachusetts, USA) found that the risk of coronary disease is almost 30% greater in psoriasis patients, and stroke risk exceeded the rate of the general population by 12%. The risk did not vary by severity of psoriasis, as patients with moderate and severe disease had a similar prevalence of heart disease and stroke. Separately, a Copenhagen University (Denmark) team studied nearly 50,000 patients who had experienced their first heart attack between 2002 and 2006, following the 462 patients with psoriasis for an average of 19.5 months and the 48,935 controls for an average of 22 months. The team found that heart attack patients with psoriasis were 26% more likely to die from cardiovascular disease, or suffer from recurrent heart attacks or strokes, and were 18% more likely to die from all causes than those without the inflammatory skin disease.
