Objectives: This study aimed to examine the characteristics of patients according to their nutritional status as assessed by five nutritional screening tools: Patient-Generated Subjective Global Assessment (PG-SGA), NUTRISCORE, Nutritional Risk Index (NRI), Prognostic Nutritional Index (PNI), and Controlling Nutritional Status (CONUT) and to compare the agreement, sensitivity, and specificity of these tools. Methods: A total of 952 gastric cancer patients who underwent gastrectomy and chemotherapy from January 2009 to December 2012 at the Samsung Medical Center were included. We categorized patients into malnourished and normal according to the five nutritional screening tools 1 month after surgery and compared their characteristics. We also calculated the Spearman partial correlation, Cohen's Kappa coefficient, the area under the curve (AUC), sensitivity, and specificity of each pair of screening tools. Results: We observed 86.24% malnutrition based on the PG-SGA and 85.82% based on the NUTRISCORE among gastric cancer patients in our study. When we applied NRI or CONUT, however, the malnutrition levels were less than 30%. Patients with malnutrition as assessed by the PG-SGA, NUTRISCORE, or NRI had lower intakes of energy and protein compared to normal patients. When NRI, PNI, or CONUT were used to identify malnutrition, lower levels of albumin, hemoglobin, total lymphocyte count, total cholesterol, and longer postoperative hospital stays were observed among patients with malnutrition compared to those without malnutrition. We found relatively high agreement between PG-SGA and NUTRISCORE; sensitivity was 90.86% and AUC was 0.78. When we compared NRI and PNI, sensitivity was 99.64% and AUC was 0.97. AUC ranged from 0.50 to 0.67 for comparisons between CONUT and each of the other nutritional screening tools. Conclusions: Our study suggests that PG-SGA and NRI have a relatively high agreement with the NUTRISCORE and PNI, respectively. Further cohort studies are needed to examine whether the nutritional status assessed by PG-SGA, NUTRISCORE, NRI, PNI, and CONUT predicts the gastric cancer prognosis.

Purpose: Colonoscopy is considered the most reliable method for the diagnosis of juvenile polyps. However, colonoscopic screening is an invasive and expensive procedure. Fecal calprotectin (FCP), a marker of intestinal inflammation, has been shown to be elevated in patients with polyps. Therefore, this study aimed to evaluate FCP as a screening biomarker for the diagnosis of juvenile polyps. Methods: This cross-sectional, observational study was conducted at the Pediatric Gastroenterology and Nutrition Department, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh. For children with polyps, colonoscopic polypectomy and histopathology were performed. FCP levels were analyzed before and 4 weeks after polypectomy in all patients. Information was recorded in a datasheet and analyzed using the computer-based program SPSS. Results: The age of the children was between 2.5 and 12 years. Approximately 93% of the polyps were found in the rectosigmoid region. Children with juvenile polyps had elevated levels of FCP before polypectomy that subsequently normalized after polypectomy. The mean FCP levels before and after polypectomy were 277±247 ㎍/g (range, 80-1,000 ㎍/g) and 48.57±38.23 ㎍/g (range, 29-140 ㎍/g) (p<0.001), respectively. The FCP levels were significantly higher in patients with multiple polyps than in those with single polyps. Moreover, mean FCP levels in patients with single and multiple polyps were 207.6±172.4 ㎍/g and 515.4±320.5 ㎍/g (p<0.001), respectively. Conclusion: Colonic juvenile polyps were found to be associated with elevated levels of FCP that normalized after polypectomy. Therefore, FCP may be recommended as a noninvasive screening biomarker for diagnosis of colonic juvenile polyps.

To assess the impact of household income and economic recession on participation in CRC screening, we estimated annual participating proportions from 2007 to 2009 for different CRC screening modalities according to household income levels. A total of 8,042 subjects were derived from the fourth Korean National Health and Nutrition Examination Survey (KNHANES IV). Multivariate logistic regression analysis was used to estimate odds ratios and 95% confidence intervals for CRC screening with household income quartiles by gender in each year. People were less likely to attend a high-cost CRC screening such as a sigmoidoscopy or colonoscopy independent of the income quartile during the economic recession. Income disparities for participating in opportunistic cancer screening appear to have existed among both males and females during the three years (2007-2009), but were most distinctive in 2009. An increase in mortality of CRC can therefore be expected due to late detection in periods of economic crisis. Accordingly, the government should expand the coverage of CRC screening to prevent excess deaths by reducing related direct and indirect costs during the economic recession.

입원환자의 초기 영양관리를 위해 개발한 영양검색 도구의 타당성을 평가 하고자 입원 후 48시간 이내에 동일한 대상자에게 KNNRS, PG-SGA, NRS-2002를 수행하였으며 그 결과를 비교 평가하였다. 1) KNNRS, PG-SGA, NRS-2002를 이용한 영양검색결과 영양상태 불량 및 영양불량 위험도가 높은 환자의 비율은 각각 28.7%, 51.3%, 48.5%로 나타났다. 2) 각 영양검색 도구에 따라 영양상태 불량 및 영양불량 위험도가 높은 것으로 나타난 환자는 영양상태 양호 및 영양불량 위험도가 낮은 환자에 비해 공통적으로 평균연령이 높고 BMI, 혈중 헤모글로빈, 총 임파구수, 알부민 수치가 유의적으로 낮았다. 3) KNNRS와 PG-SGA에 의한 영양상태 분류를 비교하였을 때 KNNRS에서 영양상태가 양호한 환자 545명 중 PG-SGA에 의해 영양상태가 양호한 환자는 331명이었다. KNNRS에서 영양상태가 불량한 환자 219명 중 PG-SGA에서도 영양상태가 불량한 환자는 178명이었다. 민감도와 특이도는 각각 60.7% (95%CI 54.2-67.0), 81.2% (95% CI 75.3-85.2)로 영양불량 상태를 판정하는데 두 도구가 임상적 관련성이 있는 것으로 사료된다. 두 도구 간 유사성 kappa 지수는 0.34로 KNNRS는 PG-SGA를 기준으로 타당한 검색도구로 검증되었다. 4) KNNRS와 NRS-2002에 의한 영양상태 분류를 비교하였을 때 KNNRS에서 영양상태가 양호한 환자 540명 중 NRS-2002에 의해 영양불량 위험도가 낮은 환자는 312명 이었다. KNNRS에서 영양상태가 불량한 환자 216명 중 NRS-2002에서 영양불량 위험도가 높은 환자는 139명이었다. 민감도와 특이도는 각각 57.8% (95%CI 53.4-60.9), 64.4% (95%CI 60.2-69.8)로 영양불량 상태를 판정하는 데 두 도구가 임상적 관련성이 적은 것으로 사료된다. 두 도구 간 유사성은 kappa 지수 0.18로 낮게 나타났다. 5) KNNRS가 PG-SGA 결과와 비교 시 타당성이 검증되었으나 영양불량환자의 비율은 28.7%로 PG-SGA와 NRS-2002의 51.3%, 48.5%에 비해 낮았다. 보다 효과적이고 적극적인 초기 영양관리 중재를 위하여 영양불량 판정 기준의 수정 보완이 필요하다. 6) 영양검색 도구의 유효성과 영양관리의 효과를 검증하기 위하여 재원일수, 합병증 여부, 질병 예후, 사망여부와의 연계연구가 필요하다.

Background: Men and women who smoke tend to show less compliance to screening guidelines than non-smokers. However, a recent study in Korea showed that self-reported female smokers constituted less than half of cotinine-verified smokers. Therefore, the aim of this study was to identify hidden smokers using cotinine-verified method and examine cancer screening behavior according to biochemically verified smoking status. Materials and Methods: Among 5,584 women aged 30 years and older who participated in the Fourth and Fifth Korea National Health and Nutrition Examination Survey (KNHANES), 372 (6.66%) hidden smokers were identified based on interview responses and verified by urinary cotinine levels. We compared cancer-screening behavior (cervical, breast, stomach, and colon cancer) of female hidden smokers to that of non-smokers and selfreported smokers by cross-sectional analysis. Results: Hidden female smokers had significantly lower adherence to breast cancer screening compared to non-smokers (aOR (adjusted odds ratio) [95% CI] = 0.71 [0.51-0.98]). Adherence to stomach cancer (aOR [95% CI] = 0.75 [0.54-1.03]) and cervical cancer (aOR [95% CI] = 0.85 [0.66-1.10]) screening was also lower among hidden female smokers compared to non-smokers. Self-reported (current) smokers showed lowest adherence to cervical cancer (aOR: 0.64, 95% CI0.47-0.87), breast cancer (0.47 [0.32-0.68]), stomach cancer (0.66[0.46-0.95]), and colon cancer (0.62 [0.38-1.01]) screening compared to non-smokers, followed by female hidden smokers, then non-smokers. These lower adherence rates of current smokers were attenuated after we incorporated hidden smokers into the current smoker group. Conclusions: Cancer screening adherence of female hidden smokers was lower than cotinine-verified non-smokers but higher than current smokers. Considering the risk of smoking-related cancer among women, identifying hidden smokers is important to encourage appropriate cancer screening.

Purpose: Low bone mineral density (BMD) is a complication in children with inflammatory bowel disease (IBD). There are limited data evaluating dual-energy x-ray absorptiometry (DXA) as a screening tool for low BMD in children with IBD. We performed a single site retrospective analysis of DXA use. Methods: Children aged 5-18 years with IBD diagnosed between 2013 to 2017 at the Royal Children's Hospital, Australia, were included. Patient demographics, measures of disease activity, DXA scores, and factors related to BMD were collected. Results: Over a median follow up of 5.1 (4-6.4) years, 72/239 (30.1%) children underwent DXA, and 28/239 (11.7%) children had a second DXA. Our DXA practice differed to consensus guidelines regarding initial screening based on height and/or body mass index (BMI) z-score (8/17 [47.1%]), and repeat surveillance (13/42 [31.0%]). Children had a median lumbar spine (LS) z-score -0.80 (-1.65-0.075). Children with LS z-score≤-2.0 (n=14) had lower weight (6.57 [1.78-23.7] vs. 51.1 [26.5-68.7], p=0.0002) and height centiles (3.62 [1.17-17.1] vs. 42 [16.9-67.1], p=0.0001), and higher faecal calprotectin (FCP) (3041 [1182-4192] vs. 585 [139-2419], p=0.009) compared to children with LS z-score>-2.0. No fractures were reported. Of 28 children who underwent a second DXA 1.6 (1.1-2.2) years following initial DXA, no significant change in z-scores occurred. Conclusion: Children with IBD had low BMD. In addition to height centile and weight centile, FCP was associated with lower BMD, and should be considered in DXA screening guidelines. Greater clinician awareness of DXA consensus guidelines is required. Future prospective studies are required.
