ABCD² score

The ABCD² score is a clinical prediction rule used to determine the risk for stroke in the days following a transient ischemic attack (TIA, a condition in which temporary brain dysfunction results from oxygen shortage in the brain). It usefulness was questioned in a 2015 review as it was not found to separate those who are low from those who are at high risk of future problems. The high score pick up 87% of people that will have a stroke in the next 7 days but many people in whom it is positive do not have problems.

The ABCD² score is based on five parameters (age, blood pressure, clinical features, duration of TIA, and presence of diabetes) scores for each item are added together to produce an overall result ranging between zero and seven. People found to have a high score are often sent to a specialist sooner. Other clinical risk factors, such as atrial fibrillation and anticoagulation treatment, as well as ongoing or recurrent TIA, are also relevant.

The ABCD² score was proposed in 2007 as a modified version of the ABCD score of 2005 (the ABCD score did not consider the presence of diabetes).In the largest study based in the emergency department testing the ABCD² score in an acute setting, the score performed poorly in both high risk and low risk patients. The study found the score to be 31.6% sensitive in high risk patients (score >5) and only 12.5% specific in low risk patients (score ≤2).

ABC (medicine)

ABC and its variations are initialism mnemonics for essential steps used by both medical professionals and lay persons (such as first aiders) when dealing with a patient. In its original form it stands for Airway, Breathing and Circulation. The protocol was originally developed as a memory aid for rescuers performing cardiopulmonary resuscitation, and the most widely known use of the initialism is in the care of the unconscious or unresponsive patient, although it is also used as a reminder of the priorities for assessment and treatment of patients in many acute medical and trauma situations, from first-aid to hospital medical treatment. Airway, breathing, and circulation are vital for life, and each is required, in that order, for the next to be effective. Since its development, the mnemonic has been extended and modified to fit the different areas in which it is used, with different versions changing the meaning of letters (such as from the original 'Circulation' to 'Compressions') or adding other letters (such as an optional "D" step for Disability or Defibrillation).

Keno

Keno /kiːnoʊ/ is a lottery-like gambling game often played at modern casinos, and also offered as a game in some lotteries.

Players wager by choosing numbers ranging from 1 through 80. After all players make their wagers, 20 numbers are drawn at random, either with a ball machine similar to ones used for lotteries and bingo, or with a random number generator.

Each casino sets its own series of pay scale choices called "paytables". The player is paid based on how many numbers selected on the ticket match the numbers drawn and the wager amount.

There are a wide variety of keno paytables from casino to casino and a large deviation in the house edge set for each of those paytables. The house edge ranges from less than 4% to well over 35%. The typical house edge for non-slot casino games is between 0% and 5%.

History

The word "keno" has French or Latin roots (Fr. quine "five winning numbers", L. quini "five each"), but by all accounts the game originated in China. Legend has it that the invention of the game saved an ancient city in time of war, and its widespread popularity helped raise funds to build the Great Wall of China. In modern China, the idea of using lotteries to fund a public institution was not accepted before the late 19th century.

SS Keno

The SS Keno is a preserved historic sternwheel paddle steamer and National Historic Site of Canada. The SS Keno is berthed in a dry dock on the waterfront of the Yukon River in Dawson City, Yukon, Canada.

The vessel was constructed in 1922, in Whitehorse, by the British Yukon Navigation Company, a subsidiary of the White Pass and Yukon Route railway company. For most of its career it transported silver, zinc and lead ore down the Stewart River from mines in the Mayo district to the confluence of the Yukon and Stewart rivers at Stewart City. It was retired from commercial service in 1951 due to the extension and improvement of the Klondike Highway in the years after World War II.

Following its withdrawal from service, the SS Keno was laid up at the BYN Co. shipyard in Whitehorse, before being selected for preservation and donated by the company to the Canadian Government in 1959. On 25 August 1960 the Keno left Whitehorse to sail downstream to Dawson City. In doing so she became the last of the Yukon's sternwheeler steamers to navigate the Yukon River under her own power. Three days later she arrived in Dawson and was subsequently installed as a tourist attraction and a permanent memorial to the approximately 250 sternwheelers that provided a vital transport service on the Yukon River and its tributaries during the latter half of the 19th and first half of the 20th centuries.
