Purpose:
The prevalence of diabetes mellitus (DM) continues to increase worldwide, and blood glucose control may reduce mortality from diabetic complications and healthcare costs. Mulberry twig (MT) has been used as a herbal medicine in Asia, and its antidiabetic efficacy has recently been reported, but research in this area is still limited. This study examined the antidiabetic effects of water extracts of MT in diabetic animals.
Methods:
Six weeks old male ICR mice were divided randomly into three groups; normal control (NC, n = 10), DM control (DC, n = 10), and MT (n = 10). Streptozotocin (STZ, 50 mg/ kg/day) was injected intraperitoneally into mice in the DC and MT groups for 5 consecutive days. After 10 days of the last STZ injection, the mice in the MT group were administered orally with MT water extracts (5 g/kg body weight) for 16 days.
Results:
The MT water extracts ameliorated the swelling of the liver in the diabetic mice and reduced the elevated levels of fasting blood and plasma glucose, total cholesterol (T-CHO), low density lipoprotein-CHO, and the ratio of high density lipotrotein (HDL)-CHO/T-CHO. The liver triglyceride (TG) and glycogen contents were also significantly lower in the MT group mice than in the DC group. The small intestine disaccharidase activity was analyzed to understand the therapeutic effects and the mechanism of MT water extracts in diabetic animals. MT group mice showed reduced lactase and sucrase activity in the proximal part of the small intestine. On the other hand, body weight, plasma insulin, TG, HDL-CHO, and hepatic T-CHO levels were similar in the DC and MT groups.
Conclusion
These results suggest that MT water extracts have antidiabetic effects and can be developed as a functional source to reduce the postprandial blood glucose or to prevent DM incidence.

Background and Objectives:
There is limited evidence regarding machine-learning prediction for the recurrence of atrial fibrillation (AF) after electrical cardioversion (ECV).This study aimed to predict the recurrence of AF after ECV using machine learning of clinical features and electrocardiograms (ECGs) in persistent AF patients.
Methods:
We analyzed patients who underwent successful ECV for persistent AF. Machine learning was designed to predict patients with 1-month recurrence. Individual 12-lead ECGs were collected before and after ECV. Various clinical features were collected and trained the extreme gradient boost (XGBoost)-based model. Ten-fold cross-validation was used to evaluate the performance of the model. The performance was compared to the C-statistics of the selected clinical features.
Results:
Among 718 patients (mean age 63.5±9.3 years, men 78.8%), AF recurred in 435(60.6%) patients after 1 month. With the XGBoost-based model, the areas under the receiver operating characteristic curves (AUROCs) were 0.57, 0.60, and 0.63 if the model was trained by clinical features, ECGs, and both (the final model), respectively. For the final model, the sensitivity, specificity, and F1-score were 84.7%, 28.2%, and 0.73, respectively. Although the AF duration showed the best predictive performance (AUROC, 0.58) among the clinical features, it was significantly lower than that of the final machine-learning model (p<0.001).Additional training of extended monitoring data of 15-minute single-lead ECG and photoplethysmography in available patients (n=261) did not significantly improve the model’s performance.
Conclusions
Machine learning showed modest performance in predicting AF recurrence after ECV in persistent AF patients, warranting further validation studies.

BACKGROUND/OBJECTIVES:
Chronic colitis is a risk factor for colorectal cancer (CRC) development in both animals and humans. Previously, we reported that a diet rich in protein (with casein as the protein source) significantly increased the risk of mouse CRC development in a dose-dependent manner. In this study, we investigated the effects of different protein sources on the risk of colitis development.MATERIALS/METHODS: Balb/c mice were divided into 7 experimental groups: 20% casein (20C), 20C-dextran sulfate sodium (DSS), 40% casein-DSS (40CD), 40% whey protein-DSS (40WD), 40% soy protein-DSS (40SD), 40% white meat-DSS (40WMD), and 40% red meatDSS (40RMD). Mice were fed an experimental diet for 4 wk and received 3% DSS in their drinking water for 6 days during the 4th wk of the experimental period.
RESULTS:
Compared to other groups, the 40CD group showed the most aggravated colitis with increased disease activity and inflammatory markers. In the 40RMD group, interleukin (IL)-6 levels were the highest among all the groups. The 40SD group showed conflicting effects, for example, elevated mortality and disease activity but decreased nitric oxide (NO) levels. The 40WD group showed attenuated colitis with increased IL-10 levels and decreased NO levels. The 40WMD group showed conflicting effects, including decreased NO levels and elevated fecal lipocalin-2 and IL-6 levels.
CONCLUSIONS
These results suggest that, at levels of 40% in the diet, casein and red meat exacerbate colitis, whereas whey protein mitigates it the most effectively.

Journal of the Korean Academy of Child and Adolescent Psychiatry 2021;32(2):71-78
Objectives:
This study was conducted to investigate the reliability and validity of the Korean version of the DSM-5 Level 2 Cross-Cutting Symptom Measure–inattention [Swanson, Nolan and Pelham, version IV (SNAP-IV)] and anger [Patient-Reported Outcome Measurement Information System (PROMIS) Anger] for parents and guardians of children aged 6–17 years.
Methods:
We included 104 children and adolescents diagnosed with attention-deficit/hyperactivity disorder (ADHD), ADHD with anxiety and depression, depressive disorder, anxiety disorder, and tic disorder with somatic symptoms (ADHD=41, depression=9, anxiety=14, ADHD+anxious depression=11, tic+somatic symptoms=29). Their ages ranged from 8 years to 15 years. The participants’ mothers completed the SNAP-IV, PROMIS Anger scale, Korean version of the IOWA Conners Rating Scale (K-IOWA), and Korean ADHD Rating Scale (K-ARS) so that the reliability and validity of the SNAP-IV and PROMIS Anger scales, which are DSM-5 scales for assessing inattention and anger of children and adolescents, could be examined.
Results:
The reliability coefficient of SNAP-IV (Cronbach’s α) was 0.94. The correlation coefficients between SNAP-IV, K-IOWA inattention, and K-ARS inattention scores ranged from 0.73 to 0.86. The mean SNAP-IV scores of the ADHD and the ADHD+anxious depression groups were significantly higher than those of the anxiety and the tic+somatic symptoms groups. The reliability coefficient of the PROMIS Anger was 0.91. The correlation coefficient between PROMIS Anger and K-IOWA oppositional/defiant scores was 0.75.The PROMIS Anger mean score of the ADHD+anxious depression group tended to be higher than that of the other groups.
Conclusion
These results suggest that the Korean version of the DSM-5 Level 2 Cross-Cutting Symptom Measure–inattention and anger for parent and guardian of child age 6–17 might be a reliable and valid test and may be useful for screening children and adolescents with ADHD.

PURPOSE: This study aimed to identify factors affecting cognitive function in stomach cancer patients. METHODS: This was a cross-sectional study designed to obtain data from stomach cancer patients. The Global Assessment of Recent Stress, Hospital Anxiety-Depression Scale, Distress Thermometer, Korean version of the Montreal Cognitive Assessment, and electronic medical records were used to assess stress, anxiety, depression, psychological distress, and cognitive function, respectively. RESULTS: Among 182 total participants, there were statistically significant differences in sex between the group of patients who received chemotherapy and those who did not (χ2=5.32, p=.029). There were statistically significant differences in stress and cognitive function between the two groups. The factors affecting cognitive function in stomach cancer patients included distress, stress, anxiety, and depression. CONCLUSION: Cognitive function should be examined with consideration of the psychological distress, stress, anxiety, and depression in patients with stomach cancer. Moreover, an improved program to manage cognitive function is needed, which includes mediation between psychological and physiological factors including stress, anxiety, and cognitive level.

Parry Romberg Syndrome (PRS), also known as idiopathic progressive hemifacial atrophy, is a rare neurocutaneous disorder characterized by loss of skin and subcutaneous fat of face, muscles, and bones causing unilateral atrophy. Most patients require only soft tissue augmentation although syndrome has varying grades of severity. In the majority of reported cases, it has been treated with surgical flap or autologous fat transplantation. However, these treatments need complicated surgical skills which take a lot of time and cost. Herein we report the first case of PRS augmented by hyaluronic acid (HA) filler in a 42-year-old female patient to suggest that HA filler could be a safe, simple, and even rational economic alternative to surgical treatment.

BACKGROUND: Colorectal cancer (CRC) is one of the most common malignancies worldwide. Approximately 10%–15% of the CRC cases have defective DNA mismatch repair (MMR) genes. Although the high level of microsatellite instability status is a predictor of favorable outcome in primary CRC, little is known about its frequency and importance in secondary CRC. Immunohistochemical staining (IHC) for MMR proteins (e.g., MLH1, MSH2, MSH6, and PMS2) has emerged as a useful technique to complement polymerase chain reaction (PCR) analyses. METHODS: In this study, comparison between the MMR system of primary CRCs and paired liver and lung metastatic lesions was done using IHC and the correlation with clinical outcomes was also examined. RESULTS: Based on IHC, 7/61 primary tumors (11.4%) showed deficient MMR systems, while 13/61 secondary tumors (21.3%) showed deficiencies. In total, 44 cases showed proficient expression in both the primary and metastatic lesions. Three cases showed deficiencies in both the primary and paired metastatic lesions. In 10 cases, proficient expression was found only in the primary lesions, and not in the corresponding metastatic lesions. In four cases, proficient expression was detected in the secondary tumor, but not in the primary tumor. CONCLUSIONS: Although each IHC result and the likely defective genes were not exactly matched between the primary and the metastatic tumors, identical results for primary and metastatic lesions were obtained in 77% of the cases (47/61). These data are in agreement with the previous microsatellite detection studies that used PCR and IHC.

Nutrition Research and Practice 2017;11(4):281-289
BACKGROUND/OBJECTIVE: The incidence of colorectal cancer (CRC) has been attributed to higher intake of fat and protein. However, reports on the relationship between protein intake and CRC are inconsistent, possibly due to the complexity of diet composition. In this study, we addressed a question whether alteration of protein intake is independently associated with colonic inflammation and colon carcinogenesis. MATERIALS/METHODS: Balb/c mice were randomly divided into 4 experimental groups: 20% protein (control, 20P, 20% casein/kg diet), 10% protein (10P, 10% casein/kg diet), 30% protein (30P, 30% casein/kg diet), and 50% protein (50P, 50% casein/kg diet) diet groups and were subjected to azoxymethane-dextran sodium sulfate induced colon carcinogenesis. RESULTS: As the protein content of the diet increased, clinical signs of colitis including loss of body weight, rectal bleeding, change in stool consistency, and shortening of the colon were worsened. This was associated with a significant decrease in the survival rate of the mice, an increase in proinflammatory protein expression in the colon, and an increase in mucosal cell proliferation. Further, colon tumor multiplicity was dramatically increased in the 30P (318%) and 50P (438%) groups compared with the control (20P) group. CONCLUSIONS: These results suggest that a high protein diet stimulates colon tumor formation by increasing colonic inflammation and proliferation.
