Development of NQ-E, Nutrition Quotient for Korean elderly: item selection and validation of factor structure / 한국영양학회지

PURPOSE: The purpose of this study was to develop a valid instrument for measuring the dietary quality and behaviors of Korean elderly. METHODS: The development of the Nutrition Quotient for Elderly (NQ-E) was conducted in three steps: item generation, item reduction, and validation. The 41 items of the NQ-E checklist were derived from a systematic literature review, expert in-depth interviews, statistical analyses of the fifth Korean National Health and Nutrition Examination Survey data, and national nutrition policies and recommendations. Pearson's correlation was used to determine the level of agreement between the questionnaires and nutrient intake level, and 24 items were selected for a nationwide survey. A total of 1,000 nationwide elderly subjects completed the checklist questionnaire. The construct validity of the NQ-E was assessed using confirmatory factor analysis, LISREL. RESULTS: The nineteen checklist items were used as final items for NQ-E. Checklist items were composed of four-factors: food behavior (6 items), balance (4 items), diversity (6 items), and moderation (3 items). The standardized path coefficients were used as the weights of the items. The NQ-E and four-factor scores were calculated according to the obtained weights of the questionnaire items. CONCLUSION: NQ-E would be a useful tool for assessing the food behavior and dietary quality of the elderly.

Characteristics of Patients Injured in Road Traffic Accidents According to the New Injury Severity Score

OBJECTIVE: To investigate the clinical characteristics of patients involved in road traffic accidents according to the New Injury Severity Score (NISS). METHODS: In this study, medical records of 1,048 patients admitted at three hospitals located in different regions between January and December 2014 were retrospectively reviewed. Only patients who received inpatient treatments covered by automobile insurance during the period were included. Accidents were classified as pedestrian, driver, passenger, motorcycle, or bicycle; and the severity of injury was assessed by the NISS. RESULTS: The proportion of pedestrian traffic accident (TA) was the highest, followed by driver, passenger, motorcycle and bicycle TA. The mean NISS was significantly higher in pedestrian and motorcycle TAs and lower in passenger TA. Analysis of differences in mean hospital length of stay (HLS) according to NISS injury severity revealed 4.97±4.86 days in the minor injury group, 8.91±5.93 days in the moderate injury group, 15.46±11.16 days in the serious injury group, 24.73±17.03 days in the severe injury group, and 30.86±34.03 days in the critical injury group (p<0.05). CONCLUSION: The study results indicated that higher NISS correlated to longer HLS, fewer home discharges, and increasing mortality. Specialized hospitals for TA patient rehabilitation are necessary to reduce disabilities in TA patients.

Mesalizine-Induced Acute Pancreatitis and Interstitial Pneumonitis in a Patient with Ulcerative Colitis / 대한소아소화기영양학회지

Ulcerative colitis (UC) is a chronic idiopathic inflammatory bowel disease. Mesalizine for the first-line therapy of UC has adverse effects include pancreatitis, pneumonia and pericarditis. UC complicated by two coexisting conditions, however, is very rare. Moreover, drug-related pulmonary toxicity is particularly rare. An 11-year-old male patient was hospitalized for recurring upper abdominal pain after meals with vomiting, hematochezia and exertional dyspnea developing at 2 weeks of mesalizine therapy for UC. The serum level of lipase was elevated. Chest X-ray and thorax computed tomography showed interstitial pneumonitis. Mesalizine was discontinued and steroid therapy was initiated. Five days after admission, symptoms were resolved and mesalizine was resumed after a drop in amylase and lipase level. Symptoms returned the following day, however, accompanied by increased the serum levels of amylase and lipase. Mesalizine was discontinued again and recurring symptoms rapidly improved.

Accuracy of Needle Placement in Cadavers: Non-Guided Versus Ultrasound-Guided

OBJECTIVE: To compare the accuracy rates of non-guided vs. ultrasound-guided needle placement in four lower limb muscles (tibialis posterior, peroneus longus, and short and long heads of the biceps femoris). METHODS: Two electromyographers examined the four muscles in each of eight lower limbs from four fresh frozen cadavers. Each electromyographer injected an assigned dye into each targeted muscle in a lower limb twice (once without guidance, another under ultrasound guidance). Therefore, four injections were done in each muscle of one lower limb. All injections were performed by two electromyographers using 18 gauge 1.5 inch or 24 gauge 2.4 inch needles to place 0.5 mL of colored acryl solution into the target muscles. The third person was blinded to the injection technique and dissected the lower limbs and determined injection accuracy. RESULTS: A 71.9% accuracy rate was achieved by blind needle placement vs. 96.9% accuracy with ultrasound-guided needle placement (p=0.001). Blind needle placement accuracy ranged from 50% to 93.8%. CONCLUSION: Ultrasound guidance produced superior accuracy compared with that of blind needle placement in most muscles. Clinicians should consider ultrasound guidance to optimize needle placement in these muscles, particularly the tibialis posterior.
