Journal of Nutrition and Health 2024;57(1):136-152
Purpose:
A comprehensive evaluation item was developed to assess adolescent dietary habits and nutritional practices, considering food intake, eating behaviors, and food culture, such as social support and food environment.
Methods:
The 59 candidate items of the evaluation checklist were obtained based on the results of the eighth Korea National Health and Nutrition Examination Survey data, Korea Dietary Reference Intakes, dietary guidelines for adolescents, Youth Risk Behavior Survey data, national nutrition policies and dietary guidelines, and literature reviews. Four hundred and three middle and high school students residing in metropolitan areas participated in a survey using the 58-item checklist, which was selected through expert evaluation and content validity ratio analysis.The construct validity of the assessment tool for the quality of adolescent diets was assessed by exploratory factor analyses to determine if the checklist items were organized properly and whether the responses to each item were distributed adequately.
Results:
The Bartlett sphericity test was significant for each area (p <0.001), and the eigen values were greater than one. The Kaiser-Meyer-Olkin and cumulative proportions by areas were food intake (0.765 and 56.8%, respectively), eating behaviors (0.544 and 64.8%, respectively), and food environment (0.699 and 62.4%, respectively). Twenty-two checklists were determined for the final evaluation items for the adolescents’ dietary habits and nutritional practices and were categorized into three distinct factors: food intake (10 items), eating behaviors (4 items), and food environment (8 items).
Conclusion
The evaluation items for adolescent dietary habits and nutritional practices is a useful checklist for easily and quickly assessing the dietary qualities and reflecting Korean adolescents and their food environmental factors related to a sustainable diet.

Neurofibromatosis is a systemic hereditary disorder with varied manifestations in bone, soft tissue, the nervous system and skin. Cutaneous manifestations of neurofibromatosis are characterized by cafe-au-lait macules, multiple neurofibromas, Lisch nodules and intertriginous freckling. Some benign or malignant tumors such as juvenile xanthogranuloma, pheochromocytoma, and malignant melanoma can accompany neurofibromatosis. But, in the English literature, no case of eccrine spiradenoma associated with neurofibromatosis has been reported. Eccrine spiradenoma is a benign uncommon neoplasm of skin adnexa. It presents as a painful, slow-growing and solitary nodule on the head or upper trunk. Here, we report a rare case of eccrine spiradenoma in a patient with neurofibromatosis.

BACKGROUND: The usefulness of the CytoDiff flow cytometric system (Beckman Coulter, USA) has been studied in various conditions, but its performance including rapidity in detecting and counting blasts, the most significant abnormal cells in the peripheral blood, has not been well evaluated. The objective of this study was to evaluate the performance of the CytoDiff differential counting method in challenging samples with blasts. METHODS: In total, 815 blood samples were analyzed. Samples flagged as "blasts" or "variant lymphocytes" and showing <10% blasts by manual counts were included. In total, 322 samples showed blasts on manual counts, ranging from 0.5% to 99%. The CytoDiff method was performed by flow cytometry (FC500; Beckman Coulter, USA) with a pre-mixed CytoDiff reagent and analyzing software (CytoDiff CXP 2.0; Beckman Coulter). RESULTS: The average time required to analyze 20 samples was approximately 60 min for manual counts, and the hands-on time for the CytoDiff method was 15 min. The correlation between the CytoDiff and manual counts was good (r>0.8) for neutrophils and lymphocytes but poor (r<0.8) for other cells. When the cutoff value of the CytoDiff blast count was set at 1%, the sensitivity was 94.4% (95% CI; 91.2-96.6) and specificity was 91.9% (95% CI; 89.0-94.1). The positive predictive value was 88.4% (95% CI; 84.4-91.5) (304/344 cases) and negative predictive value was 96.2% (95% CI; 93.9-97.7) (453/471 cases). The CytoDiff blast counts correlated well to the manual counts (r=0.9223). CONCLUSIONS: The CytoDiff method is a specific, sensitive, and rapid method for counting blasts. A cutoff value of 1% of at least 1 type of blast is recommended for positive CytoDiff blast counts.

BACKGROUND: Clinical specificity and sensitivity are essential factors in the adoption of a human papillomavirus (HPV) test as a primary screening tool and test of cure after treatment of cervical cancer and precancerous lesions (High-Risk-Lesion). Using histologically-confirmed High-Risk-Lesion-patient specimens with postoperative follow-ups, we performed clinical validation of the AdvanSure GenoBlot Assay (GenoBlot; LG Life Sciences, Korea). METHODS: The study population included 100 cases with High-Risk-Lesion, 96 with high-risk genotype positive and cervical intraepithelial neoplasia (CIN) 1 or better, and 39 with HR-negative and better than CIN 1. Forty-eight High-Risk-Lesion cases received follow-up HPV exams after surgery. For validation as a test of cure, 48 preoperative specimens (PreOP) and 78 postoperative specimens (PostOP) from 48 subjects were separately analyzed. The results of HPV DNA chip tests (HPVDNAChip; BioMedLab Co., Korea) and sequencing were cross-compared. RESULTS: The concordance rates for each genotype between HPVDNAChip and GenoBlot were between 96.3-100%. The accuracy of HPVDNAChip and GenoBlot was 87.9% and 96.6%, respectively. Genotype-based specificity for High-Risk-Lesion detection was higher than 87% for both assays; genotype 16 showed the highest sensitivity. In the PostOP group, the positive rates for HPVDNAChip and GenoBlot were 30.8% and 47.4%, respectively. CONCLUSIONS: GenoBlot showed a higher positive rate than HPVDNAChip for each genotype, with concordance rate and accuracy being similar to previous reports. As a test of cure, GenoBlot performed better than the HPVDNAChip.

Purpose:
With the 2021 revision of dietary guidelines in Korean emphasizing environmentally sustainable dietary practices, this study attempted to develop an evaluation tool to comprehensively evaluate the degree of practice and compliance with food and nutrient intake, dietary habits, and dietary culture guidelines based on the revised dietary guidelines.
Methods:
The candidate evaluation items were collected by reviewing 934 literature reviews on domestic and foreign dietary evaluations. Fifty-nine candidate items were derived by selecting the items corresponding to dietary guidelines. The content validity ratio (CVR) cutoff point evaluation was conducted with 11 experts to delete 11 items that did not meet the CVR standard. Fifty-five pilot survey candidate items were selected through revision and additional process according to expert opinion. Seventy final candidate items were selected by adding 15 questions for validity verification and reference. A pilot survey was conducted online and offline on 332 adults aged 19–64 in Seoul and the metropolitan area, and exploratory factor analysis was used to verify the construct validity of the evaluation items. Through exploratory factor analysis, the Kaiser–Meyer–Olkin, Bartlett's sphericity test, variance explained, and Cronbach's alpha criteria were confirmed in each process.
Results:
Exploratory factor analyses derived three criteria: food and nutrient intakes (11 items), eating behaviors (9 items), and dietary culture (14 items), consisting of 34 evaluation items.
Conclusion
The present scale was validated and can be used for comprehensive evaluations of the dietary guidelines for Korean adults in a simple way.

BACKGROUND/AIMS: This case-control study evaluated the safety and efficacy of endoscopic retrograde cholangiopancreatography (ERCP) in patients 90 years of age and older. METHODS: From January 2005 to August 2011, 5,070 cases of ERCP were performed at our institution. Of these, 43 cases involved patients 90 years of age and older (mean age, 91.7+/-1.9 years). A control group of 129 cases (mean age, 65.7+/-14.8 years) was matched by the patient sex, sphincterotomy, and presence of choledocholithiasis using a propensity score. The patients' medical records were retrospectively reviewed for comorbidity, periampullary diverticulum, urgent procedure, conscious sedation, technical success, procedure duration, ERCP-related complication, and death. RESULTS: Between the case and control groups, there was no significant difference with regard to comorbidity, periampullary diverticulum, and urgent procedure. Conscious sedation was performed significantly less in the patient group versus the control group (28 [65%] vs 119 [92%], respectively; p=0.000). There was no significant difference in the technical success, procedure duration, or ERCP-related complications. In both groups, there was no major bleeding or perforation related to ERCP. Post-ERCP pancreatitis occurred significantly less in the patient group compared to the control group (0 vs 13 [10%], respectively; p=0.004). One death occurred from respiratory arrest in the case group. CONCLUSIONS: ERCP can be performed safely and successfully in patients aged 90 years and older without any significant increase in complications.

BACKGROUND/AIMS: We evaluated changes of causative pathogen in acute cholangitis and their antimicrobial susceptibility over six years and differences between community-acquired and hospital-acquired acute cholangitis at our institution. METHODS: Medical records of 1,596 patients with acute cholangitis and biliary drainage between August 2006 and August 2012 were reviewed retrospectively. Cases were divided according to time: period 1 (August 2006-December 2008, n=645, 40.4%), period 2 (January 2009-August 2012, n=951, 59.6%). Cases were divided according to community-acquired cholangitis (n=1,397, 87.5%) and hospital-acquired cholangitis (n=199, 12.5%). Causative pathogens and antimicrobial susceptibility were investigated in each group. RESULTS: Causative pathogen was isolated from bile culture in 1,520 out of 1,596 cases (95.2%). The three most frequently isolated Gram-negative bacteria were extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (n=485, 30.4%), E. coli (n=237, 13.2%), and Citrobacter freundii (n=110, 6.9%). Between periods 1 and 2, prevalence of ESBL-producing E. coli and Klebsiella pneumoniae did not show significant change (36.7% vs. 32.1%, p=0.073; 6.6% vs. 6.2%, p=0.732). C. freundii showed a significant increase from period 1 to period 2 (1.7% vs. 13.2%, p=0.000). In both time periods, imipenem was the antimicrobial agent showing the highest rate of susceptibility (93.3% vs. 93.9%, p=0.783). Higher prevalence of ESBL-producing E. coli and C. freundii was observed in the hospital-acquired cholangitis group (52.1% vs. 31.2%, p=0.000; 15.9% vs. 7.3%, p=0.001). CONCLUSIONS: The most common causative pathogen of acute cholangitis was ESBL-producing E. coli. Prevalence of C. freundii increased over the time period. Imipenem should be reserved as an alternative for resistant pathogens.

BACKGROUND: Numerous studies tried to find new markers that after hematopoietic stem cell transplantation predict engraftment earlier than the conventional marker, absolute neutrophil count (ANC >500/microL). Early engraftment prediction can be achieved by a marker that reflects the release of neutrophils and monocytes into the leukopenic peripheral blood. METHODS: We analyzed blood cell parameters, including cell population data such as volume, conductivity, and light scatter in 77 patients who underwent HSCT (allogeneic, n=63; autologous, n=11) to detect possible markers. RESULTS: We identified 2 early engraftment markers of neutrophils (NEUTRO) and monocytes (MONO); a pair of mean-volume-neutrophils (MNV) and mean-conductivity-neutrophils (MNC) for NEUTRO; and a pair of mean-volume-monocytes (MMV) and mean-conductivity-monocytes (MMC) for MONO. The new markers showed distinct patterns for early engraftment wherein 1) on the engraftment day, MNV peaked as MNC notched simultaneously for every case, and 2) MMV peaked as MMC notched simultaneously in most cases. Engraftment was predicted 3.8+/-2.7 days earlier than by ANC in 74 successful engraftment cases by using NEUTRO and/or MONO: 1) 72 cases (97.3%), in which NEUTRO and/or MONO predicted earlier engraftment than ANC, 2) 1 case, in which the 3 markers predicted engraftment on the same day, and 3) 1 case, in which NEUTRO predicted engraftment on the same day as ANC and MONO failed to predict engraftment. CONCLUSIONS: By analyzing the data from daily complete blood counts, engraftment can be predicted approximately 4 days earlier than ANC >500/microL using NEUTRO as a base marker and MONO as a supplementary marker.

Pancreas metastasis of primary lung cancer is known to be very rare and if it occurs, most cases are disseminated malignant status and do not affect therapeutic plan. We experienced a case of lung cancer recurrence with solitary pancreas metastasis and mimicks primary pancreatic cancer. A 54-year old man was admitted to the hospital for further evaluation of pancreatic solitary mass. He underwent left pneumonectomy and adjuvant chemotherapy for treatment of lung adenocarcinoma 3 years ago. After surgical treatment, the lesion was confirmed metastatic adenocarcinoma of lung cancer origin. He was discharged and followed up for 24 months without recurrence.
