Objective: Bariatric surgery effectively treats non-alcoholic fatty liver disease (NAFLD). The glutamate-serine-glycine (GSG) index has emerged as a non-invasive diagnostic marker for NAFLD, but its ability to monitor treatment response remains unclear. This study investigates the GSG index's ability to monitor NAFLD's response to bariatric surgery. Methodology: Ten NAFLD participants were studied at baseline and 6 months post-bariatric surgery. Blood samples were collected for serum biomarkers and metabolomic profiling. Hepatic steatosis [proton density fat fraction (PDFF)] and fibroinflammation (cT1) were quantified with multiparametric magnetic resonance imaging (mpMRI), and hepatic stiffness with magnetic resonance elastography (MRE). Amino acids and acylcarnitines were measured with mass spectrometry. Statistical analyses included paired Student’s t-test, Wilcoxon-signed rank test, and Pearson’s correlation. Results: Eight participants provided complete data. At baseline, all had hepatic steatosis (BMI 39.3 ± 5.6 kg/m2, PDFF ≥ 5%). Post-surgery reductions in PDFF (from 12.4 ± 6.7% to 6.2 ± 2.8%, p = 0.013) and cT1 (from 823.3 ± 85.4ms to 757.5 ± 41.6ms, p = 0.039) were significant, along with the GSG index (from 0.272 ± 0.03 to 0.157 ± 0.05, p = 0.001). Conclusion The GSG index can potentially be developed as a marker for monitoring the response of patients with NAFLD to bariatric surgery.

Purpose: Although partial mesorectal excision (PME) and total mesorectal excision (TME) is primarily indicated for the upper and lower rectal cancer, respectively, few studies have evaluated whether PME or TME is more optimal for middle rectal cancer. Methods: This study included 671 patients with middle and upper rectal cancer who underwent robot-assisted PME or TME. The 2 groups were optimized by propensity score matching of sex, age, clinical stage, tumor location, and neoadjuvant treatment. Results: Complete mesorectal excision was achieved in 617 of 671 patients (92.0%), without showing a difference between the PME and TME groups. Local recurrence rate (5.3% vs. 4.3%, P>0.999) and systemic recurrence rate (8.5% vs. 16.0%, P=0.181) also did not differ between the 2 groups, in patients with middle and upper rectal cancer. The 5-year disease-free survival (81.4% vs. 74.0%, P=0.537) and overall survival (88.0% vs. 81.1%, P=0.847) also did not differ between the PME and TME groups, confined to middle rectal cancer. Moreover, 5-year recurrence and survival rates were not affected by distal resection margins of 2 cm (P=0.112) to 4 cm (P>0.999), regardless of pathological stages. Postoperative complication rate was higher in the TME than in the PME group (21.4% vs. 14.5%, P=0.027). Incontinence was independently associated with TME (odds ratio [OR], 2.009; 95% confidence interval, 1.015–3.975; P=0.045), along with older age (OR, 4.366, P<0.001) and prolonged operation time (OR, 2.196; P=0.500). Conclusion PME can be primarily recommended for patients with middle rectal cancer with lower margin of >5 cm from the anal verge.

Pancreatitis, panniculitis, and polyarthritis (PPP) syndrome is a rare but critical disease with a high mortality rate. The diagnostic dilemma of PPP syndrome is the fact that symptoms occur unexpectedly. A 48-year-old man presented with fever and painful swelling of the left foot that was initially mistaken for cellulitis and gouty arthritis. The diagnosis of PPP syndrome was made based on the abdominal CT findings and elevated pancreatic enzyme levels, lobular panniculitis with ghost cells on a skin biopsy, and polyarthritis on a bone scan. The pancreatitis and panniculitis disappeared spontaneously over time, but the polyarthritis followed its own course despite the use of anti-inflammatory agents. In addition to this case, 30 cases of PPP syndrome in the English literature were reviewed. Most of the patients had initial symptoms other than abdominal pain, leading to misdiagnosis. About one-third of them were finally diagnosed with a pancreatic tumor, of which pancreatic acinar cell carcinoma was the most dominant. They showed a mortality rate of 32.3%, associated mainly with the pancreatic malignancy. Therefore, PPP syndrome should be considered when cutaneous or osteoarticular manifestations occur in patients with pancreatitis. Active investigation and continued observations are needed for patients suspected of PPP syndrome.

PURPOSE: We assessed the influence of antenatal corticosteroid (ACS) on the inhospital outcomes of intrauterine growth restriction (IUGR) infants. METHODS: A retrospective study was conducted with singletons born at 23⁺⁰ to 33⁺⁶ weeks of gestation at Seoul National University Hospital from 2007 to 2014. We compared clinical outcomes between infants who received ACS 2 to 7 days before birth (complete ACS), at < 2 or >7 days (incomplete ACS), and those who did not receive ACS in IUGR and AGA infants. Multivariate logistic regression using Firth's penalized likelihood was performed. RESULTS: 304 neonates with 91 IUGR neonates were eligible. Among AGA neonates, mortality (adjusted odds ratio [aOR], 0.13; 95% confidence interval [CI], 0.02 to 0.78), hypotension within 7 postnatal days (aOR, 0.20; 95% CI, 0.06 to 0.64), and severe bronchopulmonary dysplasia (BPD) or death (aOR, 0.24; 95% CI, 0.07 to 0.77) were lower in complete ACS group after adjusting for pregnancy induced hypertension and uncontrolled preterm labor. Mortality (aOR, 0.18; 95% CI, 0.04 to 0.78), hypotension (aOR, 0.26; 95% CI, 0.09 to 0.70), and severe BPD or death (aOR, 0.33; 95% CI, 0.12 to 0.92) were also lower in the incomplete ACS group. Among IUGR infants, after adjusting for birth weight and 5-minute Apgar score, inhaled nitric oxide use within 14 postnatal days was lower in both complete ACS (aOR, 0.07; 95% CI, 0.01 to 0.67) and incomplete ACS (aOR, 0.04; 95% CI, 0.01 to 0.37) groups. CONCLUSION: ACS was not effective in reducing morbidities in IUGR preterm infants.

OBJECTIVE: To evaluate effects of caregiver's education program on their satisfaction, as well as patient functional recovery, performed in addition to daily conventional rehabilitation treatment. METHODS: Three hundred eleven subjects diagnosed with first-onset stroke and transferred to the Department of Physical Medicine and Rehabilitation of Inha University Hospital were surveyed. In 2015, caregivers attended an education program for acute and subacute stroke patients. Patients who received an additional rehabilitation therapy were assigned to the experimental group (n=81), whereas the control group (n=100) consisted of transfer cases in 2014 with only conventional treatment. The experimental group was classified by severity using the Korean version of the National Institutes of Health Stroke Scale (K-NIHSS), which was administered to all 181 subjects, in addition to, the Korean version of the Mini Mental Status Examination (K-MMSE), a Modified Barthel Index (K-MBI), and the Berg Balance Scale (K-BBS). Caregiver satisfaction and burden before and after education programs were assessed using the Canadian Occupational Performance Measure (COPM), as well as family burden and caregiver burnout scales. RESULTS: No significant intergroup difference was observed between initial K-NIHSS, K-MMSE, K-BBS, K-MBI scores, and times from admission to transfer. Those with moderate or severe strokes under the experimental condition showed a more significant improvement than the control group as determined by the K-NIHSS and K-BBS, as well as tendential K-MMSE and K-MBI score increases. Satisfaction was significantly greater for family members and formal caregivers of patients with strokes of moderate severity in the experimental group. CONCLUSION: The caregiver's education program for stroke subjects had a positive outcome on patients' functional improvement and caregiver satisfaction. The authors believe that the additional rehabilitation therapy with the education program aids patients to achieve functional improvements for an optimal return to social life.

The aim of this study was to assess the differences in the mortality and in-hospital outcomes of preterm infants with < 28 weeks of gestation who received ibuprofen treatment according to the presence of clinical symptoms (any of oliguria, hypotension, or moderate to severe respiratory difficulty) attributable to hemodynamically-significant patent ductus arteriosus (hsPDA) at the time of first ibuprofen treatment. In total, 91 infants born from April 2010 to March 2015 were included. Fourteen infants (15.4%) received ibuprofen treatment when there were clinical symptoms due to hsPDA (clinical symptoms group). In clinical symptoms group, infants were younger (25 [23–27] vs. 26 [23–27] weeks; P = 0.012) and lighter (655 [500–930] vs. 880 [370–1,780] grams; P < 0.001). Also, the clinical risk index for babies (CRIB)-II scores were higher and more infants received invasive ventilator care ≤ 2 postnatal days. More infants received multiple courses of ibuprofen in clinical symptoms group. Although the frequency of secondary patent ductus arteriosus (PDA) ligation and the incidence of bronchopulmonary dysplasia (BPD) was higher in the clinical symptoms group in the univariate analysis, after multivariate logistic regression analysis adjusting for the CRIB-II score, birthweight, birth year, and the invasive ventilator care ≤ 2 postnatal days, there were no significant differences in mortality, frequency of secondary ligation and in-hospital outcomes including necrotizing enterocolitis (NEC), intraventricular hemorrhage (IVH), BPD or death. Our data suggest that we can hold off on PDA treatment until the clinical symptoms become prominent.

The present study evaluated the effects of a mixture of Galla rhois and Cinnamomum cassia extracts (GCE) (1 : 1, w/w) on susceptibility to the colonization of Campylobacter (C.) jejuni in broilers. Eighty two-week-old broilers (n = 20 per group) were used to estimate the efficacy of GCE against C. jejuni infection via drinking water. Antibacterial activity testing revealed that the minimum bactericidal concentration of GCE against C. jejuni was 2.5 mg/mL. Broilers challenged with C. jejuni were administered 0.0 (Non-GCE), 2.5 (GCE-2.5), 5.0 (GCE-5.0) and 10.0 g/L (GCE-10) GCE for 7 days, and the cecal contents were collected from five broilers per group on the 1st, 3rd, 5th, and 7th day post-treatment. On day 3 post-administration, the number of C. jejuni in GCE-5.0 (p < 0.05) and GCE-10 (p < 0.01) was significantly decreased relative to Non-GCE, while on day 7 those in all GCE-treated groups were significantly decreased compared to the Non-GCE group (p < 0.001). Hematological and blood biochemical analysis revealed no significant differences in parameters between the Non-GCE and GCE-treated groups. Based on the results of the present study, GCE was identified as a safe and alternative candidate to suppress C. jejuni colonization in broilers.

OBJECTIVE: To follow up the long-term functioning in a community through assessing personal background and status based on the International Classification of Functioning, Disability and Health (ICF) after a stroke, by using a Korean version of World Health Organization Disability Assessment Scale II (K-WHODAS II). METHODS: We surveyed 146 patients diagnosed at the first-onset of acute stroke and discharged after Inha University Hospital, and 101 patients answered the K-WHODAS II survey. We analyzed the relationship of six functioning domains of K-WHODAS II with K-MMSE (Korean version of Mini-Mental State Examination) and K-MBI (Korean version of Modified Barthel Index) at admission and discharge, and personal background. All subjects were divided into five groups, according to the disease durations, to assess the functional changes and the differences of K-MMSE and K-MBI at the admission and discharge. RESULTS: K-MBI and K-MMSE at admission and discharge showed no significant differences in all five groups, respectively (p>0.05), reflecting no baseline disparity for long-term follow-up. All subjects showed positive gains of K-MBI and K-MMSE at discharge (p<0.05). The six functioning domains and total scores of K-WHODAS II had decreasing trends until 3 years after the stroke onset, but rose thereafter. Higher scores of K-MBI and K-MMSE, younger age, women, working status, higher educational level, and living with a partner were correlated with lower scores of K-WHODAS II (p<0.05). CONCLUSION: The long-term functioning after stroke was affected not only by cognitive and motor status in hospital, but also by certain kinds of personal background. K-WHODAS II may be used to monitor functioning status in a community and to assess personal backgrounds in subjects with chronic stroke.

PURPOSE: We compared neurodevelopmental outcomes according to prenatal and postnatal growth patterns in preterm infants and evaluated the proper catch-up growth timing and risk factors that affect poor neurodevelopmental outcomes. METHODS: We retrospectively reviewed the electronic medical records of preterm infants born at <32 weeks of gestational age or with <1,500 g of birth weight, who were tested with the Bayley scales of infant and toddler development, third edition (Bayley-III), at 8 and/or 18 months of corrected age in the outpatient clinic. Study populations were divided into four groups according to catch-up growth patterns, which were evaluated about <10th or ≥10th percentile at birth and at 8 or 18 months. RESULTS: In this study, 107 preterm infants were enrolled and 149 results of Bayley-III were analyzed. Infants whose lengths were within <10th percentile at birth had lower cognitive score than those whose lengths were ≥10th percentile at birth (P=0.007). The catch-up growth of length affected cognitive score (P<0.001), and the catch-up growth of head circumference affected cognitive (P<0.001) and motor scores (P=0.024). The catch-up growth of head circumference by 8 months than that by 18 months was more correlated to cognitive (R2=0.300 vs. 0.266, respectively) and motor development (R2=0.257 vs. 0.210, respectively) at 18 months. CONCLUSION: Appropriate body length at birth in preterm infants was significantly associated with optimal cognitive development. Catch-up growth of body length was related to cognitive development, while catch-up growth of head circumference was related to both cognitive and motor development. Earlier catch-up growth of head circumference was more critical for neurodevelopment than weight and length.
