Background: We evaluated the feasibility and the efficacy of Video-Assisted Thoracic Surgery (VATS) lobectomy for treating patients with non-small cell lung cancer (NSCLC) and we compared the outcomes of VATS lobectomy with those of open lobectomy. Material and Method: From 2003 to March 2008, 133 NSCLC patients underwent VATS lobectomy. The patients were selected on the basis of having clinical stage I disease on the chest CT and PET scan. The outcomes of 202 patients who underwent open lobectomy (OL group) for clinical stage I NSCLC were evaluated to compare their results with those of the patients who underwent VATS lobectomy (the VL group). Result: The number of females and the number of patients with adenocarcinoma and stage IA disease were greater in VL group (p<0.05). There was no operative mortality or major complications in the VL group. Conversion to thoracotomy was needed in 8 cases (6%), which was mostly due to bleeding. The chest tube indwelling time and the length of the postoperative hospital stay were significantly shorter in the VL group (p<0.001). The number of dissected lymph nodes and the size of tumor were significantly smaller in the VL group (p<0.001). For the pathologic stage I patients, there was no significant difference in the three-year survival rates between the two groups (p=0.15). Conclusion: VATS lobectomy is a safe procedure with low operative mortality and morbidity. VATS lobectomy is feasible for early stage NSCLC and it provides outcomes that are comparable to those for open lobectomy. Further long-term data are needed.

Background: Many video-assisted thoracic surgery (VATS) lobectomies are performed as a potential alternative to thoracotomy despite the controversy about the safety and the associated morbidity/mortality rates. Material and Method: Between November 2006 and August 2008, we performed 87 lobectomies (VATS 36, Thoracotomy 51) and we retrospectively reviewed the surgical treatment results. A VATS lobectomy was performed by a 4~5 cm thoracotomy without rib spreading and this included anatomic hilar dissection, individual vessel and bronchus stapling and lymph node dissection. Result: We studied 52 male and 35 female patients whose age ranged from 6 to 79 (average age: $59.8{\pm}15.0$ years). The cases were diagnosed with lung cancer (66) (SQC 24, ADC 38, others 4), pulmonary metastasis (2), carcinoid (2) and benign diseases (17). There was no intraoperative death. Postoperative complications were seen in 5 (15.6%) VATS and 33 (64.7%) thoracotomies, and perioperative death caused by adult respiratory distress syndrome occurred in 1 (2.8%) VATS and 3 (5.9%) thoracotomies. Three patients Underwent conversion to thoracotomy (8.3%). The mean time to chest tube removal was 6 days for VATS and 9.4 days for thoracotomy (p<0.001), and the mean length of the hospital stay was 8 days for VATS and 12.8 days for thoracotomy (p<0.001). Conclusion: VATS lobectomy can be performed safely with low morbidity/mortality rates. Furthermore, all the patients benefited from earlier postoperative rehabilitation and less pain and they were candidates for an earlier return to normal activities.

Purpose: Poor nutrition in hospitalized patients is closely linked to an increased risk of infection, which can result in complications affecting mortality, as well as increased length of hospital stay and hospital costs. Therefore, adequate nutritional support is essential to manage the nutritional risk status of patients. Nutritional support needs to be preceded by nutrition screening, in which accuracy is crucial, particularly for the initial screening. To perform initial nutrition screening of hospitalized patients, we used the Catholic Kwandong University (CKU) Nutritional Risk Screening (CKUNRS) tool, originally developed at CKU Hospital. To validate CKUNRS against the Patient-Generated Subjective Global Assessment (PG-SGA) tool, which is considered the gold standard for nutritional risk screening, results from both tools were compared. Methods: Nutritional status was evaluated in 686 adult patients admitted to CKU Hospital from May 1 to July 31, 2018 using both CKUNRS and PG-SGA. Collected data were analyzed, and the results compared, to validate CKUNRS as a nutrition screening tool. Results: The comparison of CKUNRS and PG-SGA revealed that the prevalence of nutritional risk on admission was 15.6% (n = 107) with CKUNRS and 44.6% (n = 306) with PG-SGA. The sensitivity and specificity of CKUNRS to evaluate nutritional risk status were 98.7% (96.8 ~ 99.5) and 33.3% (28.1 ~ 39.0), respectively. Thus, the sensitivity was higher, but the specificity lower compared with PG-SGA. Cohen's kappa coefficient was 0.34, indicating valid agreement between the two tools. Conclusion: This study found concordance between CKUNRS and PG-SGA. However, the prevalence of nutritional risk in hospitalized patients was higher when determined by CKUNRS, compared with that by PG-SGA. Accordingly, CKUNRS needs further modification and improvement in terms of screening criteria to promote more effective nutritional support for patients who have been admitted for inpatient care.

Purpose : Urinary tract infection (UTI) is a common bacterial infectious disease in childhood. Especially UTI in infant and young children is associated with urinary tract anomalies such as hydronephrosis, vesicoureteral reflux. The aim of this study was to compare the clinical and laboratory characteristics, and uroradiologic findings of UTI caused by pathogens other than E. coli with UTI caused by E. coli in infant and young children. Methods : We retrospectively reviewed medical records of 170 infants and children, who had been admitted for UTI to Il Sin Christian Hospital from January 2003 to December 2005. All patients were divided into two groups; E. coli and non-E. coli UTI, and they were compared for demographic data, clinical data (degree and duration of fever, time to defervescence, and length of hospital stay), underlying urinary tract anomalies (by history and ultrasonography), recurrent infection (by history and past medical records), and laboratory data [urinalysis, white blood cells (WBC) count in peripheral blood, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and serum creatinine level]. Results : Of the 170 UTI patients, the number of non-E. coli UTI was 114 (67.1%) and E. coli UTI was 56 (32.9%). As compared to E. coli group, non-E. coli group was younger in age ($0.52{\pm}0.59years$ vs $0.84{\pm}1.39years$, P<0.05), had higher rates of urinary tract anomalies [n=46 (82.1%) vs n=53 (46.5%), P<0.001], higher recurrence rate, shorter time to defervescence, less peripheral blood WBC count, lower level of CRP, lower level of ESR. Conclusion : The characteristics of non-E. coli UTI compared to E. coli UTI was younger age, milder clinical symptoms and signs, higher rates of urinary tract anomalies and higher recurrence rate.

Purpose: There have been few reports about common gastrointestinal diseases in children visiting emergency room. The aim of this study was to present basic data and their meanings about emergency room utilization in children with nonsurgical gastrointestinal disorders. Methods: The authors prospectively studied 1,228 consecutive children with gastrointestinal diseases, amongst 6,179 nonsurgical pediatric patients who visited the emergency room of Seoul Red Cross Hospital from Jan. 1st 1998 to Dec. 31st 1999. Results: 1) First visit was 60.7% of total visits and 30.7% were between 1 and 3 years of age while 80.4% were below 6 years of age. Male patients were predominant by a ratio of 1.3:1. 2) The peak month of visits was December (12.1%), and the peak time of visits was between 8:00 pm and midnight (35.9%). Average length of stay at emergency room of the total patients were 0.86 hour. 3) Five major diseases were acute gastroenteritis (44.3%), fecal impaction &/or constipation (21.3%), acute gastritis (16.4%), intussusception (4.6%), and infantile colic (4.3%) in order. 4) 19.6% of the total patients were hospitalized. Conclusion: There were differences in various distributions regarding each nonsurgical gastrointestinal disease entity in children visiting emergency room even though distributions of the total patients in our study were not so different from those in previous reports by others.

Purpose: The debate is still on-going as to whether a transthoracic esophagectomy (TTE) or a transhiatal esophagectomy(THE) is the proper treatment for patients with cardia and esophageal cancers. This study tries to demonstrate and assess the efficacy and the validity of both surgeries. Materials and Methods: In a retrospective study, data from 52 cases of patients with esophageal and/or cardia cancer who received a surgical operation during the last decade were analyzed. Results: A TTE was done in 20 cases and a THE in 32 cases. The average times for the operations were 558.0 min for a TTE and 451.7 min for a THE (P>0.05). The estimated blood loss was 1,825.0 ml in a TTE and 1459.4 ml in a THE (P>0.05). The amounts of transfusion during the operations were 3.9 units in a TTE and 2.6 units in a THE (P<0.05). Post-operative complications occurred in 15 cases of TTE and 23 cases of THE. The average length of stay in the hospital was 25.6 days for a TTE and 20.6 days for a THE. The 5-year survival rate was $10\%$ for TTE patients and $28\%$ for THE patients (P>0.05). Conclusion: For most factors, including morbidity and mortality, there was no statistically significant difference between a TTE and a THE. However, a THE is expected to be more convenient, leading to a shorter operative duration, a shorter post-operative hospitalization and lesser amounts of hemorrhage and transfusion. Hence, the THE may be a more valid or efficient surgical method for those patients with cardia and esophagus cancer who require a resection of the esophagus.

Objectives: This study aimed to examine the effectiveness of the intervention of the nutrition support team (NST) on the nutritional status of critically ill patients. Methods: The medical records of 176 adult patients who were admitted to the intensive care unit and received enteral or parenteral nutrition for more than 7 days were retrospectively analyzed. The patients were classified into the NST and non-NST groups according to whether they were referred to the NST or not. The NST group was further classified into the compliance and non-compliance groups depending on their compliance with the NST recommendations. Results: The NST referral rate was 56.8%, and the rate of compliance with the NST recommendations was 47.0%. Significantly higher energy and protein were provided to the NST and the compliance groups than to the non-NST and the non-compliance groups. The proportion of patients who reached the target calories after the initiation of enteral nutrition was significantly higher in the NST and the compliance groups than in the non-NST and the non-compliance groups. The serum albumin and hemoglobin levels significantly decreased in every group, but the changes were significantly lower in the compliance group. The nutritional status at discharge from the intensive care unit compared to the status at admission was significantly worse in the NST, non-NST, and non-compliance groups. However, the status was maintained in the compliance group. The length of stay in the intensive care unit was significantly shorter in the compliance group. Conclusions: Compliance with the NST recommendations was found to provide more calories and protein and prevent the deterioration of the nutritional status of critically ill patients. Therefore, effective communication between medical staff and the NST from the early stages of admission to the intensive care unit is needed to improve referrals to the NST and compliance with the recommendations.

Purpose: This study examined the relationship between job stress, attributes of health functional food (HFF) selection, and consumption values for information technology (IT) workers, and analyzed the factors influencing the selection of HFF to improve health by making the right choice of HFFs. Methods: Three hundred forty IT workers in Gyeonggi area participated in the study. The participants were divided into low or high job stress group. The differences in participants' general characteristics, attributes of HFF selection, and HFF consumption values were investigated, and the mediating effects of HFF consumption values on the relationship between job stress levels and the HFF selection attributes were analyzed. Results: Job stress levels were high in those IT workers with a length of service < 5 years (p = 0.013). The group with lower job stress levels had a higher tendency to consider the ingredients contained in HFF products (p < 0.001), and their efficacy (p = 0.047). They also showed greater emotional value for a sense of security from consuming HFFs to stay healthy (p = 0.047). The group with higher job stress levels had greater epistemic value in that their choice of HFFs differentiated them from the other workers (p = 0.036). Higher job stress was associated with less consideration of the intrinsic attributes such as ingredients and efficacy of the HFF selection attributes (p = -0.113), emotional value of the HFF consumption values (p = -0.136), and the functional value such as practicality, price, and safety (p = -0.134). The job stress level influenced the intrinsic attributes through the functional and emotional values, demonstrating that the functional and emotional values had appropriate mediating effects on the relationship between job stress levels and intrinsic attributes. Conclusion: Education needs to be provided for workers to relieve job stress and improve the functional and emotional values, which contributes to choosing the appropriate HFFs.

This study was to investigate the knowledge of Korean festival foods and the acculturation of American main traditional occasions among Korean American housewives residing in the New York and New Jersey area. Out of 400 questionnaires, the 271 respondents were taken. Of the respondents, 77.1% demonstrated the interest in Korean festival foods. The most important Korean festivals were Chusuk (52.0%), Sulnal(46.9%) and Daeborum (1.1%). In order to make the Korean festival foods to be international foods, the most vital factor was taste and flavor (39.5%), cooking method (34.7%), preservation (10.3%), sanitation (8.1%) and nutrition (7.4%). American Thanksgiving Day was the most important occasion among the Korean American housewives. The factors that keep the American traditional occasions were related to whether the respondents had an occupation or the length of stay in the U.S.A. But in case of Korean festival foods, the factors cannot be applied. On the contrary, they do still keep the tradition and the interest of Korean festival foods in U.S.A. As a result of that, the Korean festival foods in the U.S.A. are systemized for the preservation and popularization for the coming Korean generation.

Purpose: The current study was designed for development of a simplified malnutrition screening tool (SMST) for hospitalized patients using readily available laboratory and patient information and for evaluation of its reliability compared to well-established tools, such as PGSGA and NRS-2002. Methods: Anthropometric and biochemical measurements, as well as a few subjective assessments, of 903 patients who were preclassified by their nutritional status according to PGSGA were analyzed. Among them, a combination of factors, including age, BMI, albumin, cholesterol, total protein, hematocrit, and changes in body weight and food intake, were statistically selected as variables for SMST. Results: According to SMST, 620 patients (68.7%) were classified as the normal group and 283 patients (31.3%) were classified as the malnutrition group. Significant differences in age, albumin, TLC, BMI, hemoglobin, hematocrit, total protein, cholesterol, and length of stay were observed between the two groups. For inter-methods reliability, the screening results by SMST were compared with those by PGSGA and NRS-2002. The comparison with PGSGA and NRS-2002 showed 'Substantial agreement' (sensitivity 94.4%, specificity 88.4%, ${\kappa}$ = 0.747) and 'Moderate agreement' (sensitivity 96.1%, specificity 79.5%, ${\kappa}$ = 0.505), respectively, indicating that SMST held high inter-methods reliability. Conclusion: In conclusion, SMST, based on readily available laboratory and patient information and simple subjective assessments on changes in food intake and body weight, may be a useful alternative tool with a simple but reliable risk index, especially in resource-limited domestic hospitals.
