Nutrition and cancer | Year: 2012
We assessed which nutrition evaluation method [subjective global assessment (SGA); malnutrition universal screening tool (MUST); nutritional risk index (NRI)] provided the most efficacious combination of high validity, low cost, and ease of use to examine and improve the status of malnutrition for colorectal cancer (CRC) patients. The SGA, MUST, and NRI scales were used to analyze the preoperative status of malnutrition for 45 CRC patients in a medical center in Taiwan. Differences in the reliability of the 3 methods were compared using the kappa (κ) coefficient of agreement. Lengths of hospital stays were compared using the Mann-Whitney U test to examine the effect of malnutrition in CRC patients. The SGA κ coefficient was higher with the MUST than with the NRI. Preoperative and postoperative weight losses were significantly different on the NRI, and the longer the length of the hospital stay, the greater was the weight loss. Although the SGA had a higher validity and lower cost than the NRI, we recommend using the MUST method for a routine nutrition evaluation because it is easier to use and is less expensive than the SGA and the NRI.

An illuminated surgical retractor system includes a surgical retractor and at least one illumination device. The surgical retractor includes an outer ring, a light-transmissive hollow inner ring, and a tubular retraction membrane which extends between the output ring and the inner ring and which has a first open end connected to and spread open by the outer ring and a second open end connected to and spread open by the inner ring. The illumination device is disposed in the inner ring and is operable to emit a light beam. The illumination device includes a magnetic component which is responsive to an applied magnetic field to cause the illumination device to change a direction in which the light beam is emitted.

A tracheal tube includes an airway tubular body, an inflatable cuff disposed on the airway tubular body, a suction conduit extending along the airway tubular body to terminate at a suction opening, and a guiding unit disposed on the airway tubular body and adjacent to the suction opening. The guiding unit includes at least one guiding member having a plurality of ribs. Each two adjacent ones of the ribs define a guiding groove that extends toward the suction opening and that terminates at a confluent region in fluid communication with the suction opening so as to guide secretions in the trachea to the suction opening.

An introducer device (3) is for use in Nuss procedure to guide a steel bar (4) in retrieving an insertion route which passes through and between a patients sternum (903) and heart (904). The introducer device (3) includes an elongated introducer body (31) and an ultrasonic probe (312). The introducer body (31) extends in a lengthwise direction to terminate at a leading tip end (311) for coupling the concave steel bar (4) to retrieve the insertion route, and a grip end (312) opposite to the leading tip (311), and has a curve segment (313) configured to establish the insertion route when the leading tip end (311) is led to pass through and between the sternum (903) and the heart (904) . The curve segment (313) has a concave sternum-side surface (314) and a convex heart-side surface (315). The ultrasonic probe (32) is coupled to the leading tip end (311) to transmit ultrasonic waves towards the heart (904) and to receive reflected ultrasonic waves traveling from the heart (904) when passing through and between the sternum (903) and the heart (904).
