To PEG or not to PEG.
Patients with adequate intestinal function who are unable to eat may benefit from enteral tube feeding. Percutaneous endoscopic gastrostomy (PEG) is preferred when prolonged treatment is envisaged. PEG feeding will reduce morbidity and mortality in many such patients by reversing malnutrition. The increasing numbers of elderly patients with chronic diseases have resulted in an increased demand ...
متن کاملTrying to Understand PEG
Parsing Expression Grammar (PEG) encodes a recursivedescent parser with limited backtracking. Its properties are useful in many applications. In its appearance, PEG is almost identical to a grammar in the Extended Backus-Naur Form (EBNF), but may define a different language. Recent research formulated some conditions under which PEG is equivalent to its interpretation as EBNF. However, PEG has ...
متن کاملFrom EBNF to PEG
Parsing Expression Grammar (PEG) encodes a recursive-descent parser with limited backtracking. The parser has many useful properties, and with the use of memoization, it works in a linear time. In its appearance, PEG is almost identical to a grammar in Extended Backus-Naur Form (EBNF), but usually defines a different language. However, in some cases only minor typographical changes are sufficie...
متن کاملMore About Converting BNF to PEG
Parsing Expression Grammar (PEG) encodes a recursive-descent parser with limited backtracking. The parser has many useful properties. Converting PEG to an executable parser is a rather straightforward task. Unfortunately, PEG is not well understood as a language definition tool. It is thus of a practical interest to construct PEGs for languages specified in some familiar way, such as Backus-Nau...
متن کاملLow Volume Polyethylene Glycol (PEG) Plus Ascorbic Acid, a Valid Alternative to Standard PEG
Adequate bowel preparation is essential to improve colonoscopy quality. Inadequate bowel preparation may result in lower colonoscopy completion rate, longer duration of colonoscopy, and lower diagnostic yield for polyps. Polyethylene glycol (PEG) has been shown to be safe and effective, and thus regarded as the gold standard for bowel preparation before colonoscopy. However, the standard PEG re...
