Rheumatoid arthritis (RA) is a long lasting autoimmune disorder that primarily affects joints. It typically results in warm, swollen, and painful joints. Pain and stiffness often worsen following rest. Most commonly, the wrist and hands are involved, with the same joints typically involved on both sides of the body. The disease may also affect other parts of the body. This may result in a low red blood cell count, inflammation around the lungs, and inflammation around the heart. Fever and low energy may also be present. Often, symptoms come on gradually over weeks to months.
While the cause of rheumatoid arthritis is not clear, it is believed to involve a combination of genetic and environmental factors. The underlying mechanism involves the body's immune system attacking the joints. This results in inflammation and thickening of the joint capsule. It also affects the underlying bone and cartilage. The diagnosis is made mostly on the basis of a person's signs and symptoms.X-rays and laboratory testing may support a diagnosis or exclude other diseases with similar symptoms. Other diseases that may present similarly include systemic lupus erythematosus, psoriatic arthritis, and fibromyalgia among others.
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.
Everyday Health, Inc. is a digital media company which owns websites and produces content relating to health and wellness.
The company was founded in 2002 by entrepreneurs Benjamin Wolin and Michael Keriakos to invest in the creation of online health content for major "offline" health brands. By 2011, their network of sites had over 28 million unique viewers per month, garnering over $100 million in yearly revenue, including major partnerships with brands and personalities such as Denise Austin and the South Beach Diet. In 2010, Everyday Health acquired professional website MedPage Today. The company attempted in IPO in November 2010, which ultimately failed due to changes in “circumstances regarding the securities markets.”
Throughout 2011, the company began to diversify into digital media: in July 2011 it announced that it would be co-producing a self-titled TV series with Litton Entertainment for Litton's Weekend Adventure, a new Saturday morning syndication package of E/I programming aired by affiliates of ABC. It also hired Paul Slavin, a veteran producer from ABC News, to help operate a new studio for the company. In October 2011, YouTube announced that Everyday Health would become part of its Original Channel Initiative, which aimed to fund the production of professionally produced original web content. Everyday Health would launch Everyday Health TV through the program, featuring original health and lifestyle-related series.
