BACKGROUND/OBJECTIVES: The doubly labeled water (DLW) method is considered the gold standard for the measurement of total energy expenditure (TEE), which serves to estimate energy requirements. This study evaluated the accuracy of predictive dietary reference intake (DRI) equations for determining the estimated energy requirements (EER) of Korean adults by using the DLW as a reference method. SUBJECTS/METHODS: Seventy-one participants (35 men and 36 women) aged between 20 and 49 years were included in the study. The subjects’ EER, calculated by using the DRI equation (EERDRI), was compared with their TEE measured by the DLW method (TEEDLW). RESULTS: The DRI equations for EER underestimated TEE by -36.3 kcal/day (-1.3%) in men and -104.5 kcal/day (-4.9%) in women. The percentages of accurate predictions among subjects were 77.1% in men and 62.9% in women. There was a strong linear correlation between EERDRI and TEEDLW (r = 0.783, P < 0.001 in men and r = 0.810, P < 0.001 in women). CONCLUSIONS: The present study supports the use of DRI prediction equations to determine EER in Korean adults. More studies are needed to confirm our results and to assess the validity of these equations in other population groups, including children, adolescents, and older adults.

Purpose: We analyzed the pulmonary function and risk factors of allergic rhinitis (AR) in dust mite-sensitized children with current AR and no history of asthma. Methods: In this cross-sectional study, demographic and disease-related information was obtained from 1,792 Korean children aged 9?12 years using a questionnaire, skin-prick testing, spirometric analysis, and methacholine challenge testing. Results: A total of 672 children were analyzed. The control group consisted of 583 children without any allergic diseases who were not sensitized to 16 common allergens. The group with current AR and dust mite sensitization consisted of 89 children. Binary logistic regression analysis showed that helminth infection (adjusted odds ratio [aOR], 2.88; 95% confidence interval [CI], 1.23?6.77) and antibiotic use during infancy (aOR, 1.89; 95% CI, 1.10?3.25) were the risk factors. Pet ownership (aOR, 0.32; 95% CI, 0.15?0.69) and older siblings (aOR, 0.58; 95% CI, 0.35?0.96) were protective factors. Spirometry results did not differ between the control and dust mite-induced AR groups. None of the children showed a bronchodilator response. However, 8.5%, 7.1%, and 2.1% of the control-group children and 28.7%, 23.0%, and 8.0% of the dust mite-induced AR-group children showed methacholine PC20 (provocative concentration of methacholine causing a 20% fall in forced expiratory volume in 1 second) values of ≤25 mg/mL, ≤16 mg/mL, and ≤8 mg/mL, respectively (P<0.01). Conclusion: The prevalence of current dust mite-induced AR may be reduced by controlling environmental factors. Even though the spirometry results seemed to be normal, bronchial hyperresponsiveness occurred more frequently in children with dust mite-induced AR than in normal children.

Background Few scales are currently available to evaluate changes in hand volume. We aimed to develop a hand grading scale for quantitative assessments of dorsal hand volume with additional consideration of changes in skin texture; to validate and prove the precision and reproducibility of the new scale; and to demonstrate the presence of clinically significant differences between grades on the scale. Methods Five experienced plastic surgeons developed the Hand Volume Rating Scale (HVRS) and rated 91 images. Another five plastic surgeons validated the scale using 50 randomly selected images. Intra- and inter-rater agreement was calculated using the weighted kappa statistic and intraclass correlation coefficients (ICCs). Paired images were also evaluated to verify whether the scale reflected clinical differences. Results The intra-rater agreement was 0.95 (95% confidence interval, 0.922–0.974). The interrater ICCs were excellent (first rating, 0.94; second rating, 0.94). Image pairs that differed by 1, 2, and 3 grades were considered to contain clinically relevant differences in 80%, 100%, and 100% of cases, respectively, while 84% of image pairs of the same grade were found not to show clinically relevant differences. This confirmed that the scale of the HVRS corresponded to clinically relevant distinctions. Conclusions The scale was proven to be precise, reproducible, and reflective of clinical differences.

BACKGROUND/OBJECTIVES The doubly labeled water (DLW) method is the gold standard for estimating total energy expenditure (TEE) and is also useful for verifying the validities of dietary evaluation tools. In this study, we compared the accuracy of total energy intakes (TEI) estimated by the 24-h diet recall method with TEE obtained using the doubly labeled water method. SUBJECTS/METHODS This study involved 71 subjects aged 20–49 yrs. Over a 14-day period, three 24-h diet recalls per subject (2 weekdays and 1 weekend day) were used to estimate energy intakes, while TEE was measured using the DLW method. The paired t-test was used to determine the significance of differences between TEI and TEE results, and the accuracy of the 24-h recall method was determined by accuracy predictions percentage, root mean square error, and bias. RESULTS Average study subject age was 33.4 ± 8.6 yrs. The association between TEI and TEE was positive and significant (r = 0.463, P < 0.001), and the difference between TEI (2,084.3 ± 684.2 kcal/day) and TEE (2,401.7 ± 480.3 kcal/day) was also significant (P < 0.001). In all study subjects, mean TEI was 12.0% (307.5 ± 629.3 kcal/day) less than mean TEE, and 12.2% (349.4 ± 632.5 kcal/day) less in men and 11.8% (266.7 ± 632.5 kcal/day) less in women. Rates of TEI underprediction for all study subjects, men, and women, were 60.5%, 51.4%, and 66.7%, respectively. CONCLUSIONS This study shows that 24-h diet recall underreports energy intakes. More research is needed to corroborate our findings and evaluate the accuracy of 24-h recall with respect to additional demographics.

The purpose of this study was to verify the effects of behavior problems upon the parenting stress of developmentally delayed infants. The subjects comprised 148 male and female infants with developmental delays in the department of child psychiatry and rehabilitation at a general hospital in Seoul, Korea. The parents of infants were assessed by means of the Child Behavior Checklist 1.5-5 and the K-PSI. The results revealed the following: First, behavior problems of developmentally delayed infants and parenting stress had significantly positive correlations. Among the scales, the total scores of behavior problems showed the highest correlations. Second, the parenting stress of pervasive developmental disorder group was higher than the communication disorder group. Third, withdrawn scale significantly predicted parenting stress among 7 syndrome scales. Amongst the 5 DSM oriented scales, affective problems, pervasive developmental problems and attention deficit/hyperactivity problem scales significantly predicted parenting stress as orderly. Fourth, DSM affective problems scale significantly predicted parenting stress in communication disorder group. Additionally, withdrawn and DSM affective problems scales had an effect on parenting stress in the pervasive developmental disorder group.

Acceleration of Mesenchymal-to-Epithelial Transition (MET) during Direct Reprogramming Using Natural Compounds

( Ji-hye Seo ),( Si Won Jang ),( Young-joo Jeon ),( So Young Eun ),( Yean Ju Hong ),( Jeong Tae Do ),( Jung-il Chae ),( Hyun Woo Choi ) 한국미생물생명공학회 2022 Journal of microbiology and biotechnology Vol.32 No.10

Induced pluripotent stem cells (iPSCs) can be generated from somatic cells using Oct4, Sox2, Klf4, and c-Myc (OSKM). Small molecules can enhance reprogramming. Licochalcone D (LCD), a flavonoid compound present mainly in the roots of Glycyrrhiza inflata, acts on known signaling pathways involved in transcriptional activity and signal transduction, including the PGC1-α and MAPK families. In this study, we demonstrated that LCD improved reprogramming efficiency. LCD-treated iPSCs (LCD-iPSCs) expressed pluripotency-related genes Oct4, Sox2, Nanog, and Prdm14. Moreover, LCD-iPSCs differentiated into all three germ layers in vitro and formed chimeras. The mesenchymalto- epithelial transition (MET) is critical for somatic cell reprogramming. We found that the expression levels of mesenchymal genes (Snail2 and Twist) decreased and those of epithelial genes (DSP, Cldn3, Crb3, and Ocln) dramatically increased in OR-MEF (OG2^+/+/ROSA26^+/+) cells treated with LCD for 3 days, indicating that MET effectively occurred in LCD-treated OR-MEF cells. Thus, LCD enhanced the generation of iPSCs from somatic cells by promoting MET at the early stages of reprogramming.

Objective This study aimed to explore the characteristics and factors related to changes in cognitive function in vulnerable individuals with cognitive impairment during the coronavirus disease 2019 (COVID-19) pandemic.Methods Among patients who visited a local university hospital with subjective cognitive complaints, those who had been tested for cognitive function at least once after the onset of COVID-19 and tested regularly at least three times within the last 5 years were included (1st, the initial screening; 2nd, the test immediately before the COVID-19 pandemic; 3rd, the most recent test after the pandemic). Finally, 108 patients were included in this study. They were divided into groups according to whether the Clinical Dementia Rating (CDR) was maintained/improved and deteriorated. We investigated the characteristics of the changes in cognitive function and related factors during COVID-19.Results When comparing CDR changes before and after COVID-19, there was no significant difference between the two groups (p=0.317). Alternatively, the main effect of the time when the test was conducted was significant (p<0.001). There was also a significant difference in the interaction between the groups and time. When the effect of the interaction was analyzed, the CDR score of the maintained/ improved group significantly decreased before COVID-19 (1st–2nd) (p=0.045). After COVID-19 (2nd–3rd), the CDR score of the deteriorated group was significantly higher than that of the maintained/improved group (p<0.001). Mini-Mental State Examination recall memory and changes in activity during COVID-19 were significantly associated with CDR deterioration.Conclusion Memory dysfunction and decreased activity during the COVID-19 pandemic are strongly related to the deterioration of cognitive impairment.
