ABSTRACT

BACKGROUND: The present study was designed to explore the pathological role of non-canonical NLRC4 inflammasome in glioma. METHODS: This retrospective study included bioinformatical analysis, including survival, gene ontology, ssGSEA, cox regression, IPA and drug repositioning with TCGA and DepMap database. Experimental validations were conducted in glioma patient's sample and evaluated with histological or cellular functional analysis. RESULT: Clinical dataset analysis revealed that non-canonical NLRC4 inflammasomes significantly contribute to glioma progression and poor survival rates. Experimental validation was revealed that the expression of non-canonical NLRC4 inflammasomes were co-localized with astrocytes in malignant gliomas, with a sustained clinical correlation observed between astrocytes and inflammasome signatures. Indeed, the formation of an inflammatory microenvironment increased in malignant gliomas, leading to pyroptosis, known as inflammatory cell death. Molecular interaction analysis revealed that NF-κB pathways potentially serve as the connecting point between the canonical and noncanonical pathways of the NLRC4 inflammasome. Finally, drug repositioning analysis of non-canonical NLRC4 inflammasome-associated molecules revealed that MK-5108, PF4981517, and CTEP may represent effective options for glioma therapy. CONCLUSION: The findings of this study suggest that non-canonical NLRC4 inflammasomes contribute to poor prognosis in patients with glioma and induce an inflammatory microenvironment. We propose the pathological phenomenon of non-canonical NLRC4 inflammasomes and several therapeutic strategies based on the modulation of the inflammatory tumor microenvironment.

ABSTRACT

BACKGROUND: Well-characterized preclinical models are essential for immune-oncology research. We investigated the feasibility of our humanized mouse model for evaluating the long-term efficacy of immunotherapy and biomarkers. METHODS: Humanized mice were generated by injecting human fetal cord blood-derived CD34+ hematopoietic stem cells to NOD-scid IL2rγnull (NSG) mice myeloablated with irradiation or busulfan. The humanization success was defined as a 25% or higher ratio of human CD45+ cells to mice peripheral blood mononuclear cells. RESULTS: Busulfan was ultimately selected as the appropriate myeloablative method because it provided a higher success rate of humanization (approximately 80%) and longer survival time (45 weeks). We proved the development of functional T cells by demonstrating the anticancer effect of the programmed cell death-1 (PD-1) inhibitor in our humanized mice but not in non-humanized NSG mice. After confirming the long-lasting humanization state (45 weeks), we further investigated the response durability of the PD-1 inhibitor and biomarkers in our humanized mice. Early increase in serum tumor necrosis factor α levels, late increase in serum interleukin 6 levels and increase in tumor-infiltrating CD8+ T lymphocytes correlated more with a durable response over 60 days than with a non-durable response. CONCLUSIONS: Our CD34+ humanized mouse model is the first in vivo platform for testing the long-term efficacy of anticancer immunotherapies and biomarkers, given that none of the preclinical models has ever been evaluated for such a long duration.

ABSTRACT

BACKGROUND: Although previous studies have established a close relationship between caloric intake and metabolic syndrome, there is limited research exploring the impact of meal frequency adjusted by caloric intake on metabolic syndrome (MetS). OBJECTIVE: To evaluate the association of meal frequency and MetS after adjusting for confounding factors including caloric intake in Korean men and women. METHODS: We analyzed the national representative data of a total 12,389 adults (5171 men, 7218 women) from the Korean National Health and Nutrition Examination Survey (KNHANES) 2010-2012. Subjects were categorized as eating 3 meals/day (MF3) or 2 or fewer meals/day (MF ≤ 2). Daily caloric intake was calculated using CAN-Pro 4.0 (The Korean Nutrition Society, Seoul, Korea). RESULTS: The prevalence of components of MetS differed significantly according to meal frequency in both men and women. In an unadjusted analysis, the prevalence of MetS in women was significantly higher in the MF3 group than the MF ≤ 2 group (27.5% vs. 17.8%, P < 0.001), whereas the prevalence of MetS in men did not differ between the MF3 and MF ≤ 2 groups (24.6% vs. 22.7%, P = 0.281). However, after adjusting for age, caloric intake, smoking status, alcohol consumption, physical activity, income, and education level, men in the MF ≤ 2 group had an increased risk of metabolic syndrome compared to men in the MF3 group (OR = 1.37, 95%, CI = 1.12-1.67). On the other hand, meal frequency did not affect the risk of metabolic syndrome in women after adjusting for confounding factors including caloric intake (OR = 1.09, 95%, CI = 0.90-1.31). CONCLUSIONS: This study suggests that lower meal frequency adjusted for caloric intake, physical activity, age, smoking, alcohol, income, and education may be associated with increased risk of MetS in Korean men.

ABSTRACT

BACKGROUND: The objective of the current study was to determine whether there was an association between urinary albumin excretion and cardiovascular disease (CVD) risk by estimating the Framingham Risk Score (FRS) in postmenopausal women without diabetes. METHODS: This study was based on data from the Korea National Health and Nutrition Examination Survey, which was conducted by the Korean Ministry of Health and Welfare in 2011 to 2013. Data on 2,316 postmenopausal women from a total of 24,594 participants was included in the analysis. RESULTS: The mean FRS was significantly different in each of the urinary albumin to creatinine ratio (UACR) subgroups, and it increased with UACR. The FRS was 12.69±0.12 in the optimal group, 14.30±0.19 in the intermediate normal group, 14.62±0.26 in the high normal group, and 15.86±0.36 in the microalbuminuria group. After fully adjusting for potential confounding factors, high normal levels and microalbuminuria were significantly associated with the highest tertile of FRS ([odds ratio (OR), 1.642; 95% confidence interval (CI), 1.124 to 2.400] and [OR, 3.385; 95% CI, 2.088 to 5.488], respectively) compared with the optimal subgroup. High normal levels and microalbuminuria were also significantly associated with a ≥10% 10-year risk of CVD ([OR, 1.853; 95% CI, 1.122 to 3.060] and [OR, 2.831; 95% CI, 1.327 to 6.037], respectively) after adjusting for potential confounding covariates. CONCLUSION: Urinary albumin excretion reflects CVD risk in postmenopausal women without diabetes, and high normal levels and microalbuminuria were independently associated with a higher risk of CVD.

ABSTRACT

CONTEXT: Parity has been implicated in many health consequences for women in later life. OBJECTIVE: To determine whether there is an association between parity and body size phenotypes in postmenopausal women. DESIGN AND PARTICIPANTS: This study was based on data from the Korean National Health and Nutrition Examination Survey, conducted during 2010-2012. Of the 25 534 participants, data from 3347 postmenopausal women were included in the analysis. RESULTS: In analyses stratified by the metabolically abnormal obese (MAO) and metabolically healthy and normal weight phenotypes, women with parities of 3-4 births or more than or equal to 5 births were significantly associated with the MAO phenotype (odds ratio [OR] 1.396 [95% confidence interval (CI) 1.077-1.810] and OR 1.978 [1.392-2.811], respectively) compared with those with a parity of 1-2 births after adjusting for age, sociodemographic factors, lifestyle behaviors, and reproductive factors. A similar significant association of parity with the MAO phenotype was also found when we analyzed the parity number as a continuous variable in a comparison of the MAO and metabolically abnormal but normal weight phenotypes (OR 1.116 [1.012-1.232]). In grouping of the MAO and metabolically healthy but obese phenotypes, women who had experienced a parity of 3-4 births or more than or equal to 5 births were significantly associated with the MAO phenotype (OR 1.459 [1.025-2.076] and OR 1.989 [1.211-3.265], respectively) after adjustment for the above covariates. CONCLUSIONS: Parity influenced the body size phenotype in postmenopausal women, and higher parity was independently associated with a higher risk of the MAO phenotype in postmenopausal women.

ABSTRACT

A collaborative exercise on DNA methylation based body fluid identification was conducted by seven laboratories. For this project, a multiplex methylation SNaPshot reaction composed of seven CpG markers was used for the identification of four body fluids, including blood, saliva, semen, and vaginal fluid. A total of 30 specimens were prepared and distributed to participating laboratories after thorough testing. The required experiments included four increasingly complex tasks: (1) CE of a purified single-base extension reaction product, (2) multiplex PCR and multiplex single-base extension reaction of bisulfite-modified DNA, (3) bisulfite conversion of genomic DNA, and (4) extraction of genomic DNA from body fluid samples. In tasks 2, 3 and 4, one or more mixtures were analyzed, and specimens containing both known and unknown body fluid sources were used. Six of the laboratories generated consistent body fluid typing results for specimens of bisulfite-converted DNA and genomic DNA. One laboratory failed to set up appropriate conditions for capillary analysis of reference single-base extension products. In general, variation in the values obtained for DNA methylation analysis between laboratories increased with the complexity of the required experiments. However, all laboratories concurred on the interpretation of the DNA methylation profiles produced. Although the establishment of interpretational guidelines on DNA methylation based body fluid identification has yet to be performed, this study supports the addition of DNA methylation profiling to forensic body fluid typing.

ABSTRACT

BACKGROUND: Arterial stiffness is an important factor in atherosclerosis. Thus we examined whether aerobic exercise could reduce arterial stiffness in obese women with type 2 diabetes without diabetic complication. METHODS: A total of 35 women with type 2 diabetes (body mass index, 26.6±2.8 kg/m(2); age, 56.4±1.9 years; duration of diabetes, 4.7±4.8 years) were assigned to aerobic exercise group (AEG) or control group (CG). AEG completed a 12-week exercise program (3.6 to 5.2 metabolic equivalents, 3 day/week, 60 min/day), with their exercise activities monitored by accelerometers. We measured abdominal total fat area (TFA), visceral fat area (VFA), and subcutaneous fat area (SFA) by computed tomography, insulin sensitivity by insulin tolerance test (KITT), and augmentation index (AIx) by SphygmoCor at baseline and at the end of the 12-week program. RESULTS: The AIx was improved in the AEG compared with the CG (P<0.001). The percent change of AIx had significant correlation with the improvement of physical activity energy expenditure (PAEE), aerobic capacity, TFA, and SFA (r=-0.416, P=0.013; r=0.560, P<0.001; r=0.489, P=0.003; r=0.531, P=0.001, respectively), but not with insulin sensitivity, energy intake, or VFA. CONCLUSION: Improvement in aortic stiffness by aerobic exercise is related with the improvement of aerobic capacity, PAEE, and total fat but not with insulin sensitivity or energy intake in obese women with type 2 diabetes.

ABSTRACT

OBJECTIVE: To demonstrate that the PTEN/PI3K/Akt/NF-κB pathway plays an important role in regulating the prostate cancer stem-like cell population by upregulating ABCG2. METHODS: Targeted PTEN knockdown in human prostate DU145 and 22Rv1 cells using a small interfering RNA were confirmed by immunoblot analysis using antibodies of PTEN, phospho-Akt, Akt, and α-tubulin. Knockdown PTEN DU145 and 22Rv1 cells were augmented, and the stem cell-like properties were examined by cell viability and tumor sphere formation and treated by Akt IV inhibitor to provide the signal transduction pathway. Luciferase activity assays were performed. RESULTS: The knockdown of PTEN in prostate cancer cell lines increased the stem-like properties of the cells, including their sphere-forming ability, stem cell population number, epithelial-mesenchymal transition-related gene expression, and ABCG2 expression. Additionally, PTEN expression was highly associated with elevated expression of phospho-Akt. Treatment with an Akt inhibitor suppressed the PTEN-mediated effects on the properties of these stem-like cells as well as drug resistance, ABCG2 expression, and the NF-κB pathway. CONCLUSION: The loss of PTEN in prostate cancer cells resulted in an increased PI3K/Akt pathway. Due to the Akt activation, PTEN loss may play an important role in prostate cancer by promoting cancer stemness through a mechanism that involves enhanced NF-κB signaling.

ABSTRACT

OBJECTIVES: The liver-secreted protein fetuin-A is associated with insulin resistance, metabolic syndrome, type 2 diabetes and atherosclerosis. We examined the effect of caloric restriction (CR) on fetuin-A levels and concomitant changes in hepatic steatosis and cardiovascular risk factors in rats and humans. DESIGN AND SUBJECTS: We performed a randomized, controlled clinical trial to examine circulating fetuin-A levels and cardiovascular risk parameters including visceral fat area (VFA), atherogenic lipid profile, inflammatory markers, adipokines levels and brachial artery endothelial function in 76 overweight women with type 2 diabetes before and after 12 weeks of CR. In addition, the effects of CR on hepatic steatosis and fetuin-A mRNA expression were evaluated in Otuska Long Evans Tokushima Fatty (OLETF) rats, an animal model of obesity and type 2 diabetes. RESULTS: Circulating fetuin-A levels were significantly decreased after 12 weeks of CR and were accompanied by improvements in VFA, blood pressure, glucose, lipid profiles and liver function. The CR group also showed a significant decrease in apolipoprotein B, leptin and insulin resistance compared to those in the control group, although endothelial function was not different. Multiple regression analysis showed that the changes in fetuin-A levels were independently associated with CR and changes in hsCRP and adiponectin (R² = 0·156). Moreover, CR significantly reduced hepatic steatosis and fetuin-A expression, as well as weight, glucose, total cholesterol and triglyceride levels, in OLETF rats. CONCLUSION: Caloric restriction significantly reduced the hepatic expression of fetuin-A and its circulating levels and improved several cardiovascular risk factors in obese rats and humans with type 2 diabetes.

ABSTRACT

The purpose of this study was to determine whether the frequency of adverse drug events can be extracted by analyzing narrative nursing statements documented in standardized terminology-based electronic nursing records. For this study, we reviewed the narrative nursing documentations of 487 admissions of 355 cancer patients who were treated with cisplatin at a tertiary-care hospital in Korea. Narrative nursing statements with the terms "adverse drug reaction," "allergy," "hypersensitivity," and other adverse drug events listed in the safety information were analyzed. In addition, nausea, one of the most frequent adverse drug events, was further examined. Narrative statements documenting the presence or absence of an "adverse drug reaction," "allergy," and "hypersensitivity" were found in 162 admissions (33.3%). The presence or absence of adverse drug events due to cisplatin was documented in 476 admissions (97.7%). At least one adverse drug event was noted in 258 admissions (53.0%). The presence of nausea was documented in 214 admissions (43.9%), and the mean duration of nausea was 5.2 days. The results of this study suggest that adverse drug events can be monitored using narrative nursing statements documented in standardized terminology-based electronic nursing records.

ABSTRACT

OBJECTIVES: Heart-type fatty acid binding protein (H-FABP) is enriched in neuronal cell body as well as myocardium, and is rapidly released from damaged neuron into circulation in cerebral ischemia. We performed a comparative analysis between plasma H-FABP and S100B levels in the acute phase of ischemic stroke. METHODS: The present study included 111 consecutive patients with acute ischemic stroke and 127 control subjects. Measurement of plasma H-FABP and S100B levels was conducted during acute phase (<24 h) of stroke. Clinical severities were evaluated by the use of NIHSS scores at admission and mRS score at 3 months after symptom onset. RESULTS: Both the plasma H-FABP and S100B levels were significantly higher in stroke group than control group. In multiple logistic regression analysis, statistical significance of both markers remained significant after adjusting the vascular risk factors. In the receiver operator characteristic (ROC) curve analysis, neither H-FABP (area under curve [AUC]=0.71, P<0.001, sensitivity: 59.5%, specificity: 79.5%) nor S100B (AUC=0.70, P<0.001, sensitivity: 54.0%, specificity: 83.5%) showed a favorable degree of diagnostic value to discriminate stroke from stroke mimic. Plasma H-FABP (r=0.46, P<0.01) and S100B (r=0.45, P<0.01) were correlated with initial NIHSS score, and both marker were significantly higher in patients with poor clinical outcome. CONCLUSION: Although plasma H-FABP is elevated in the acute phase of ischemic stroke, the diagnostic accuracy of H-FABP as a sole marker is not sufficient to be applied in the clinical setting. Plasma H-FABP can be used as a potential marker for stroke prognosis.

ABSTRACT

CONTEXT: Low levels of soluble receptor for advanced glycation end-products (sRAGE) have been linked to systemic inflammation and vascular complications in patients with type 2 diabetes mellitus (T2DM). OBJECTIVE: We examined the effects of exercise on sRAGE and its association with diverse cardiometabolic risk factors and indicators of atherosclerosis in patients with T2DM. DESIGN, SETTING, AND PARTICIPANTS: Seventy-five patients with T2DM were randomized into a control group and an aerobic exercise group (60 min at moderate intensity, five times/wk for 12 wk). MAIN OUTCOME MEASURES: We evaluated sRAGE, energy expenditure, dietary energy intake, cardiorespiratory fitness, inflammatory markers, visceral fat area, pulse-wave velocity, and flow-mediated dilatation. RESULTS: Baseline sRAGE concentrations were independently associated with age, glycated hemoglobin, glucose, triglyceride, and high-density lipoprotein cholesterol levels (R2=0.244). After 12 wk of exercise training, the exercise group showed significantly decreased body weight, waist circumference, blood pressure, glycated hemoglobin, apolipoprotein B, and free fatty acid levels. Concurrently, cardiorespiratory fitness assessed by oxygen uptake at anaerobic threshold was improved, and body fat percentage and visceral fat area were significantly decreased in the exercise group, although pulse-wave velocity and flow-mediated dilatation were not changed. Furthermore, sRAGE levels were increased and high-sensitivity C-reactive protein levels were decreased in the exercise group but not in the control group. Percent change of sRAGE level was negatively correlated with that of high-sensitivity C-reactive protein during the study period (r=-0.27; P=0.019). CONCLUSIONS: Aerobic exercise increases sRAGE levels along with improvement of various cardiometabolic risk factors in patients with T2DM.

ABSTRACT

BACKGROUND: We investigated the effects of exercise intensity on abdominal and mid-thigh adipose tissue, attenuation of skeletal muscle, and insulin sensitivity in overweight women with type 2 diabetes mellitus (T2DM). METHODS: Twenty-eight patients were randomly assigned to control (CG, n=12), moderate intensity exercise (MEG, n=8), or vigorous intensity exercise (VEG, n=8) group. Subjects in both exercise groups completed a 12-week exercise program (MEG, 3.6 to 5.2 METs; VEG, ≥5.2 METs) that was monitored by accelerometers. We assessed body mass index (BMI), total fat area (TFA), visceral fat area (VFA), subcutaneous fat area (SFA), mid-thigh intramuscular adipose tissue (TIMAT), total skeletal muscle (TTM), low density skeletal muscle (TLDM), and normal density skeletal muscle (TNDM) using computed tomography, and measured insulin sensitivity with an insulin tolerance test (K(ITT)), before and after the intervention. RESULTS: At baseline, the mean age was 53.8±7.9 years, duration of diabetes was 3.8±2.3 years, and BMI was 26.6±2.6 kg/m(2). After 12 weeks, the percent change (%C) in BMI, TIMAT, and TLDM were not different among three groups. However, %C in TFA and VFA were significantly reduced in MEG compared to CG (P=0.026 and P=0.008, respectively). %C SFA was significantly reduced in VEG compared to CG (P=0.038) and %C TTM, TNDM, and K(ITT) were significantly increased in VEG compared to the CG (P=0.044, P=0.007, and P=0.016, respectively). CONCLUSION: Although there was no difference in the change in BMI among groups, TFA and VFA were more reduced in MEG, and only VEG increased TTM, TNDM, and insulin sensitivity compared to CG.

ABSTRACT

To explore the usefulness of narrative nursing records documented using a standardized terminology-based electronic nursing records system, we conducted three different studies on (1) the gaps between the required nursing care time and the actual nursing care time, (2) the practice variations in pressure ulcer care, and (3) the surveillance of adverse drug events. The narrative nursing notes, documented at the point of care using standardized nursing statements, were extracted from the clinical data repository at a teaching hospital in Korea and analyzed. Our findings were: the pediatric and geriatric units showed relatively high staffing needs; overall incidence rate of pressure ulcer among the intensive-care patients was 15.0% and the nursing interventions provided for pressure-ulcer care varied depending on nursing units; and at least one adverse drug event was noted in 53.0% of the cancer patients who were treated with cisplatin. A standardized nursing terminology-based electronic nursing record system allowed us to explore answers to different various research questions.

ABSTRACT

BACKGROUND: There is controversy over whether aerobic or resistance exercise is more effective for improving endothelial function in type 2 diabetes mellitus (T2DM). This study was aimed to investigate the effects of an aerobic and resistance training program on endothelial function, and the influences of glycemic control, body weight changes, and aerobic capacity in T2DM. METHODS: Total 40 overweight women with T2DM were assigned into 3 groups: an aerobic exercise group (AEG, n=13), resistance exercise group (REG, n=12), and control group (CG, n=15), and followed either brisk walking for the AEG or resistance band training for the REG, 60 minutes per day, 5 days per week for 12 weeks with monitoring daily activity using accelerometers. We assessed endothelial function by flow-mediated dilation (FMD), and aerobic capacity by oxygen uptake at anaerobic threshold (AT_VO(2)) at baseline and following training program. RESULTS: The mean participants' age was 57.0±6.8 years, and body mass index (BMI) was 27.0±2.3 kg/m(2). After intervention, FMD increased by 2.2±1.9% in AEG, which differed from REG and CG (P=0.002), despite of decreased body weight (BW) in both AG and RG (2.8±2.5%, P=0.002; 1.6±2.0%, P=0.017, respectively). A significant increased AT_VO(2) and decreased HbA1c were found only in AEG. In all participants, FMD was changed with the significant relations to the AT_VO(2) (r=0.348, P=0.035), but not to HbA1c levels or BW. CONCLUSION: Aerobic exercise appears to be more beneficial than resistance exercise for improving endothelial function in T2DM. In addition, aerobic capacity could be a better predictor of changes in FMD than BW and glycemic control.

ABSTRACT

BACKGROUND: Insulin resistance is related to central obesity and the amount of skeletal muscle. A simple and practical anthropometric marker for muscle mass is not known, although waist circumference (WC) is used as an indicator of abdominal obesity. The aims of this study were to investigate whether arm (AC) and thigh circumferences (TC) can be used as an indicator of muscle mass and if they are related to muscle strength. METHODS: A total of 110 obese (body mass index [BMI]≥25 kg/m(2)) women with type 2 diabetes were enrolled, and WC, AC, and TC were measured. Abdominal visceral fat (AVF), subcutaneous fat (ASF), and total fat (ATF) were assessed by computed tomography, regional muscle (MM), and fat mass by dual-energy X-ray absorptiometry, muscle strength by one repetition maximum (1RM) of both extremities (chest and leg press) and insulin resistance by K(ITT). RESULTS: The mean age was 56.2±7.3 years, duration of diabetes was 4.2±4.4 years, and BMI was 27.2±2.8 kg/m(2). WC was correlated with ATF, AVF, and ASF (r=0.728, P<0.001; r=0.515, P<0.001; r=0.608, P<0.001, respectively). Arm MM was correlated with AC (r=0.500, P<0.001), and leg MM with TC (r=0.291, P=0.002). Upper 1RM was related to AC/WC ratio (r=0.359, P<0.001), and lower 1RM was to TC/WC ratio (r=0.286, P=0.003). Insulin resistance had significant relations with AVF, WC, and total MM (r=-0.262, P=0.008; r=-0.217, P=0.029; r=0.160, P=0.031, respectively). CONCLUSION: The muscle mass was related to extremity circumferences, and muscle strength was to extremity/waist circumference ratio in obese women with type 2 diabetes.

ABSTRACT

BACKGROUND: Koreans eat rice, which is usually served in a rice bowl. We investigated the effect of a meal plan using small rice bowls on the total energy intake (TEI) and the marcronutrient intake in Korean men with type 2 diabetes. METHODS: A total of 62 men with type 2 diabetes were divided by body mass index (BMI) (normal weight [NW], BMI<23 kg/m(2); overweight [OW], 23≤BMI<25 kg/m(2); obese [OB], BMI≥25 kg/m(2)) and proportions of carbohydrate intake to TEI (PCI) (low carbohydrate intake [LC], <55%; recommended carbohydrate intake [RC], ≥55% and ≤60%; high carbohydrate intake [HC], >60%). The 3-day dietary records were analyzed for TEI and proportions of macronutrients, before and 2 weeks after a small-sized (300 mL) rice bowl based education was given. RESULTS: There were no significant differences in the age and BMI within the sub-groups by BMI and PCI groups. In baseline, the ratio of TEI to recommended total energy intake (RTR) of OW and OB were higher than that of NW. The PCI of HC was higher than that of LC and alcohol intake of HC was lower than that of LC. After education, the reduction of RTREI in OB was higher than that in OW and NW. The reduction of PCI in HC was higher than that of LC. CONCLUSION: A small rice bowl based meal plan was effective for the reduction of energy intake and control of marcronutrient intake in Korean obese men with type 2 diabetes consuming a high carbohydrate diet.

ABSTRACT

The purpose of this study was to assess vitamin B(6) intake and status in Korean patients with newly diagnosed type 2 diabetes. Sixty-four patients with newly diagnosed type 2 diabetes and 8-11% glycated hemoglobin (A1C), along with 28 age-matched non-diabetic subjects, participated. Dietary vitamin B(6) intake was estimated by the 24 hour recall method and plasma pyridoxal 5'-phosphate (PLP) was measured. There was a significant difference in daily total calorie intake between the diabetic and non-diabetic groups (1,917 ± 376 vs 2,093 ± 311 kcal). There were no differences in intake of total vitamin B(6) (2.51 ± 0.91 vs 2.53 ± 0.81 mg/d) or vitamin B(6)/1,000 kcal (1.31 ± 0.42 vs 1.20 ± 0.32 mg) between the diabetic and non-diabetic groups, andI intakes of total vitamin B(6) were above the Korean RDA in both groups (180.0 ± 57.9 vs 179.0 ± 65.4). There was a higher percentage of diabetic subjects whose plasma PLP concentration was < 30 nmol/L compared to non-diabetic group. Plasma PLP levels tended to be lower in the diabetic subjects than in the non-diabetic subjects, although the difference was not statistically significant due to a large standard deviation (80.0 ± 61.2 nmol/L vs 68.2 ± 38.5 nmol/L). Nevertheless, plasma PLP levels should be monitored in pre-diabetic patients with diabetic risk factors as well as in newly diagnosed diabetic patients for long-term management of diabetes, even though this factor is not a major risk factor that contributes to the development of degenerative complications in certain patients.
