Background: Recently, a study comprising adult patients with sepsis admitted in the intensive care unit (ICU) was conducted. The patients were treated with high doses of intravenous ascorbic acid, thiamine, and hydrocortisone; the clinical outcomes demonstrated significant therapeutic benefits. The mortality rate in children with sepsis is approximately 25%. However, the effects of additional treatment with ascorbic acid and thiamine ("vitamin protocol") in children are rarely investigated. Methods: A retrospective analysis was performed using medical records of patients diagnosed with sepsis and admitted to the pediatric ICU (PICU) between September 2016 and June 2019. The control group received treatment only as per sepsis protocol, whereas the treated group received both sepsis protocol and the vitamin protocol. The primary endpoint was change in Vasoactive-Inotropic Score (VIS) for 5 days. The secondary endpoints included the length of stay in the PICU, duration of using mechanical ventilators and vasopressors, and mortality rate. Results: The number of patients in the treated and control groups was 33 and 24, respectively. The treated group showed greater decrease in their VIS for 5 days than the control group (44.4 vs 18.6); however, the difference was not statistically significant. The length of stay in the PICU was significantly longer for the treated group than for the control group [10.0 days (Interquartile range (IQR), 6-18) vs 4.5 days (IQR, 4-10.3); p=0.004]. Conclusions: No significant treatment benefits were observed following vitamin protocol administration to the pediatric patients with sepsis. Further studies are necessary for improving the efficacy and safety of the vitamin protocol.

Background/Aims: This study aimed to determine whether vitamin C in addition to indomethacin decreases the occurrence and severity of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) occurrence and severity. Methods: This randomized clinical trial included patients undergoing ERCP. The participants were administered either rectal indomethacin (100 mg) plus an injection of vitamin C (500 mg) or rectal indomethacin (100 mg) alone just before ERCP. The primary outcomes were PEP occurrence and severity. The secondary amylase and lipase levels were determined after 24 hours. Results: A total of 344 patients completed the study. Based on intention-to-treat analysis, the PEP rates were 9.9% for indomethacin plus vitamin C plus indomethacin and 15.7% for indomethacin alone. Regarding the per-protocol analysis, the PEP rates were 9.7% and 15.7% in the combination and indomethacin arms, respectively. There was a remarkable difference between the two arms in PEP occurrence and severity on intention-to-treat and per-protocol analyses (p=0.034 and p=0.031, respectively). The post-ERCP lipase and amylase concentrations were lower in the combination arm than in the indomethacin alone arm (p=0.034 and p=0.029, respectively). Conclusions: Vitamin C injection in addition to rectal indomethacin reduced PEP occurrence and severity.

Background: This study investigated the relationship between depressive symptoms and physical fitness, obesity indices, and vitamin D status in office workers. Methods: The subjects were 514 adults with more 30 years of experience as office workers in the city of Seoul. Lifestyle risk factors, obesity indices, physical fitness, and serum vitamin D levels were assessed with a standardized protocol. The Beck Depression Inventory (BDI) was used to assess depression status. Vitamin D status was assessed by measuring serum 25-hydroxyvitamin D concentrations. Based on the BDI scores, participants were classified into no depression (ND, $BDI{\leq}9$), mild depression (MiD, $10{\leq}BDI{\leq}15$), and moderate depression (MoD, $16{\leq}BDI{\leq}23$) groups. Results: Compared with the high cardiorespriatory fitness group, the low cardiorespiratory fitness (men OR=2.618, women OR=1.596) an middle cardiorespiratory fitness group (men OR=1.256, women OR=1.110) had significantly higher odds ratio for having depressive symptoms, even after adjustment for age, hypertension, diabetes, hyperlipidemia, cardiovascular disease, alcohol intake, smoking, body mass index (BMI), percent body fat (%BF), and waist circumference (WC). Compared with the insufficient or deficient vitamin D group , the sufficient vitamin D group had significantly lower odds ratios for having depressive symptoms (men OR=0.121, women OR=0.114), even after adjustment for age, hypertension, diabetes, hyperlipidemia, cardiovascular disease, alcohol intake, smoking, BMI, %BF, and WC. Conclusion: Vitamin D supplementation and outdoor activities should be key components of a lifestyle intervention against office workers' depression.

The aim of this study is to evaluate the effects of vitamin or mineral supplements on the conception rates of dairy heifers when replacing the last injection of GnRH with hCG in ovsynch protocol (experiment 1) and also to investigate whether the estrus synchronization treatment in the heifer stage affects the conception rates after $1^{st}$ parturition (experiment 2). In experiment 1, 50 heifers were randomly assigned into 3 groups: 20 heifers each in groups 1 and 2, and 10 in group 3. All three groups were treated with an intramuscular injection of GnRH on day 0 (day 0 = the day of program start), $PGF_{2{\alpha}}$ on day 7 and hCG on day 9, and were inseminated on day 10, 12~16h after hCG injection. In group 1 (vitamin group), the heifers were treated with an intramuscular injection of 5 ml of vitamin-ADE $500^{(R)}$, and group 2 (mineral group) was treated twice with an intramuscular injection of 30 ml of mineral supplement-LAPTOVET$^{(R)}$ on a one-week interval beginning on the day of hormone treatment (day 0 and day 7 respectively). Group 3 (control) was treated only with hormones. Pregnancy diagnosis was performed by ultrasonography through a rectal probe. First service conception rates (FSCR) and average services per conception (ASPC) were recorded for all subjects. Of the total 50 heifers, 6 (2 in group 1, 3 in group 2, and 1 in group 3) heifers were eliminated due to accidents during experiment 1. FSCRs were 58.8% (10/17), 66.7% (12/18) and 44.4% (4/9) in groups 1, 2 and 3, respectively. ASPCs were $1.53{\pm}0.72$, $1.27{\pm}0.59$ and $1.63{\pm}0.74$ in groups 1, 2 and 3, respectively. Although there were no significant difference between the groups, relatively good results (higher FSCR and lower ASPC) were obtained in both group 1 and 2. In experiment 2, 11 primiparous cows from group 2 of experiment 1 in heifer stage which had been treated both with the hormones for estrus synchronizing and mineral supplements (ES group), and 12 primiparous cows treated only with minerals (non-ES group) were compared to examine the effects of estrus synchronization program on conception rates after $1^{st}$ parturition. Following the examination, postpartum ASPCs were $1.55{\pm}0.82$ and $2.17{\pm}1.47$ in ES group and non-ES group, respectively. The postpartum average days open (ADO) were $116{\pm}56$ and $197{\pm}93$ in ES group and non-ES group, respectively. Although there were no significant difference between the two groups, desirable results (lower ASPC and shorter ADO) were found in ES group after $1^{st}$ parturiton. In conclusion, experiment 1 indicates that vitamin or mineral supplement with ovsynch protocol may have some positive effect on FSCR and ASPC of dairy heifers, and in experiment 2, ES program in heifer stage had a positive effect on ASPC and ADO following $1^{st}$ parturition.

Curcumin (CMN) is known to have beneficial role in anorexia, coryza, cough, diabetic wounds, and hepatic disorders apart from its inherent antioxidant effects. Therefore, the present study was aimed to evaluate antioxidant effect of CMN in prevention of nephrolithiasis in rats-induced by ethylene glycol (EG) and Vitamin D3 (Vit. D3). Male Wistar rats (175 - 200 g) were randomized in groups like control, EG + Vit. D3 induced nephrolithiatiatic rats, CMN treated rats, CMN + EG + Vit. D3 treated rats, Vit. E + EG + Vit. D3 treated rats. Urine was collected weekly throughout the experimental protocol and estimated for calcium oxalate (CaO) count. After completion of experimental protocol serum was estimated for blood urea nitrogen and creatinine. Both the kidneys were excised and used to evaluate levels of biomarkers of oxidative stress and calcium oxalate crystal deposition by histopathological studies. Administration of EG and Vit. D3 to rats resulted in increased oxidative stress, hyperoxaluria and renal deposition of CaO crystals. Supplementation with CMN improves kidney function, reduces elevated oxidative stress, urinary oxalate level and renal deposition of CaO which shows its protective action in nephrolithiasis. The increased deposition of stone in the kidney and stone forming constituents of nephrolithiatic rats were effectively lowered by treatment of CMN.

BACKGROUND/OBJECTIVES: The efficacy of Lab4 probiotic and vitamin C combination on the prevention of upper respiratory tract infections (URTIs) was investigated in two studies with children. Our objective was to pool dataset of 57 preschool children from the PROCHILD study (ISRCTN28722693) and the dataset of 50 preschool matched cohort from the PROCHILD-2 study (ISRCTN26587549) to evaluate the impact of probiotic/vitamin C combination on the prevention of upper respiratory tract symptoms and provide a more robust assessment of effect using detailed individual level data. SUBJECTS/METHODS: The children were supplemented daily for 6 months with either the multistrain probiotic (1.25×10¹⁰ cfu/tablet consisting of two strains of Lactobacillus acidophilus CUL21 and CUL60, Bifidobacterium bifidum CUL20 and Bifidobacterium animalis subsp. lactis CUL34) plus 50 mg vitamin C or a placebo. RESULTS: In the pooled analysis of the individual participant data (per protocol population), significant reductions were observed for the incidence (-25%; 95% confidence interval [CI], 0.66, 0.85; P < 0.0001) and duration (-14.9 days; 95% CI, -24.8, -5.1; P = 0.0030) of typical URTI symptoms in the active group compared with the placebo. The incidence rates of absenteeism from preschool (IR ratio, 0.75; 95% CI, 0.66, 0.86; P < 0.0001), paediatric visits (IR ratio, 0.56; 95% CI, 0.47; 0.68; P < 0.0001) and antibiotic usage (IR ratio, 0.53; 95% CI, 0.39, 0.71; P < 0.0001) were also significantly reduced. CONCLUSION: The pooled analysis findings of comparable preschool cohorts from two studies indicate that the supplementation with probiotic and vitamin C combination is beneficial in the prevention and management of URTI symptoms.

본 연구는 대규모 GMO 격리포장에서 비타민 A 영양성분이 강화된 황금벼의 안정성 평가에 대한 가이드라인 및 프로토콜의 개발하고자 수행하였다. GM 작물의 상업화는 환경과 인간건강에 대한 영향을 포함하여 GM 작물에 대한 신뢰성을 구축하기 위해서도 GM 작물을 상업화하기 이전에 보다 체계적인 과학적인 검증자료가 제공되어야 한다. 경북대학교 농업생명과학대학 GMO 실습격리포장에서 총 사용면적 $4,700m^2$에서 비타민 A 강화벼(황금벼)와 모품종인 '낙동'에 대해 농업적인 특성과 병 발생양상을 조사하였다. 일반적으로 포장에서 형질전환체 작물의 수장, 수수 등은 '낙동'과는 차이가 났다. 황금벼와 '낙동'의 간장, 미립특성은 '낙동'과 유사하지만, 수량은 등숙율과 1,000립중의 감소에 기인된 것으로 조사되었다. 잎도열병과 잎집무늬마름병의 병방제가의 차이는 났지만 유의성은 나지 않는 것으로 나타났다. 이 실험결과는 GM 작물에 대한 환경과 인간과의 그 밖의 위해성에 대한 농업적인 특성, 병 발생양상을 일차적으로 안정성 평가를 위한 체계적인 프로토콜로 도출할 수 있을 것이다.
