[EX Q]: Diarrhea is the third leading infectious cause of death worldwide and is estimated to be responsible for approximately 2 million deaths a year. While many infectious causes of diarrhea have been established, approximately 40% of all diarrhea cases are of unknown etiology. In an effort to identify novel viruses that may be causal agents of diarrhea, we used high throughput mass sequencing to analyze stool samples collected from patients with acute diarrhea.', "Sequences with limited similarity to known picornaviruses were detected in a stool sample collected in Australia from a child with acute diarrhea. Using a combination of mass sequencing, RT-PCR, 5' RACE and 3' RACE, a 6383 bp fragment of the viral genome was sequenced. Phylogenetic analysis demonstrated that this virus was highly divergent from, but most closely related to, members of the genus Kobuvirus. We have tentatively named this novel virus klassevirus 1. We also detected klassevirus 1 by RT-PCR in a diarrhea specimen collected from a patient in St. Louis, United States as well as in untreated sewage collected in Barcelona, Spain.
[EX A]: Is klassevirus 1 , a previously undescribed member of the family Picornaviridae , globally widespread?

[EX Q]: Unintentional injuries are the leading cause of death in children, and falls are the most common type of unintentional injury in the US. The incidence of falls from windows, a common cause of death in urban areas, has not been described outside major cities such as New York and Chicago, and rates in urban and suburban areas have not been compared.', 'To estimate the incidence and identify the population at risk for falls from windows among children in Hamilton County, Ohio.', "Retrospective case series identified using Cincinnati Children's Hospital Medical Center (CHMC) Trauma Registry.", 'Hamilton County, Ohio, which has urban and nonurban areas.', 'Children less than 15 years old residing in Hamilton County, Ohio, presenting to CHMC in Cincinnati, Ohio, after a fall from a window between January 1, 1991, and December 31, 1997.', 'Annual incidence by age, race, gender, and residence of those who fell from windows.', 'Over the 7-year study period, 86 (6.3%) of 1,363 falls were from windows. The mortality rate for falls from windows was 4.7%, compared to 0.07% for all other falls presenting to CHMC (P<.0001). Children 0-4 years old had a higher rate of falls than children aged 5-14 (14.6/100,000 vs. 2.0/100,000) (P<.0001). Males were twice as likely to fall as females (P<.016), and black children were three times more likely to fall than non-black children (P<.002). The incidence of falls in the city of Cincinnati was four times that of the non-urban area (P<.0002).
[EX A]: Does childhood injuries and deaths due to fall from windows?

[EX Q]: Health information has a major role in the planning of future healthcare provision. With current reconfiguration and cost saving measures, further demands are being placed on acute hospitals.', 'To examine the elderly admissions and the referral documentation of older patients admitted to a tertiary level hospital.', 'A retrospective analysis of primary care referral documentation for all acute admissions of patients over 75\xa0years to University Hospital Limerick (UHL) over a 2-month period. Documentation was analysed on the basis of patient demographics, presenting complaint and referral source. Primary care referral documentation was then analysed on the basis of presenting complaint, patient demographics, referrer details, and the clinical information provided.', "Over the 2-month period there were a total of 381 elderly admissions through the Emergency department. The most common presenting complaint was with shortness of breath (21.5\xa0%). 42.5\xa0% of admissions were from a primary care setting. 31.1\xa0% of referrals were typed and 47.0\xa0% handwritten. Over 90\xa0% of referrals contained the patient's name, date of birth and address. 98.7\xa0% of referrals included a presenting complaint and 54\xa0% included a past medical history. 20\xa0% of referrals listed known drug allergies, while 9.3\xa0% documented social history or baseline functional status. Referral letters from general practice and after-hour services were largely similar.
