The risk of vitamin D deficiency varies with the season. The frequency of vitamin D deficiency in migraine patients and its association with migraine are unclear.
We retrospectively evaluated ...first-visit migraine patients between January 2016 and May 2017, and investigated the demographics, season, migraine subtypes, frequency, severity, and impact of migraine, psychological and sleep variables, climate factors, and vitamin D levels. The nonfasting serum 25-hydroxyvitamin D concentration was measured to determine the vitamin D level, with deficiency of vitamin D defined as a concentration of <20 ng/mL.
In total, 157 patients with migraine aged 37.0±8.6 years (mean±standard deviation) were analyzed. Their serum level of vitamin D was 15.9±7.4 ng/mL. Vitamin D deficiency was present in 77.1% of the patients, and occurred more frequently in spring and winter than in summer and autumn (89.1%, 85.7%, 72.4%, and 61.7%, respectively; p=0.008). In multivariate Poisson regression analysis, monthly headache was 1.203 times (95% confidence interval=1.046-1.383, p=0.009) more frequent in patients with vitamin D deficiency than in those without deficiency after adjusting for demographics, season, migraine subtype, depression, anxiety, and sleep quality. These associations were consistently noted in subgroup analysis of episodic migraine (odds ratio=1.266, p=0.033) and chronic migraine (odds ratio=1.390, p=0.041).
Our study found that a larger number of monthly days with headache was related to vitamin D deficiency among migraineurs. Future studies should attempt to confirm the causal relationship between vitamin D deficiency and migraine.
Mobile health applications have been developed to support diabetes self-management, but their effectiveness could depend on patient engagement. Therefore, patient engagement must be examined through ...multifactorial tailored behavioral interventions from an individual perspective.
This study aims to evaluate the usefulness of a novel user utility score (UUS) as a tool to measure patient engagement by using a mobile health application for diabetes management.
We conducted a subanalysis of results from a 12-month randomized controlled trial of a tailored mobile coaching (TMC) system among insurance policyholders with type 2 diabetes. UUS was calculated as the sum of the scores for 4 major core components (range 0-8): frequency of self-monitoring blood glucose testing, dietary and exercise records, and message reading rate. We explored the association between UUS for the first 3 months and glycemic control over 12 months. In addition, we investigated the relationship of UUS with blood pressure, lipid profile, and self-report scales assessing diabetes self-management.
We divided 72 participants into 2 groups based on UUS for the first 3 months: UUS:0-4 (n=38) and UUS:5-8 (n=34). There was a significant between-group difference in glycated hemoglobin test (HbA
) levels for the 12-months study period (P=.011). The HbA
decrement at 12 months in the UUS:5-8 group was greater than that of the UUS:0-4 group -0.92 (SD 1.24%) vs -0.33 (SD 0.80%); P=.049. After adjusting for confounding factors, UUS was significantly associated with changes in HbA
at 3, 6, and 12 months; the regression coefficients were -0.113 (SD 0.040; P=.006), -0.143 (SD 0.045; P=.002), and -0.136 (SD 0.052; P=.011), respectively. Change differences in other health outcomes between the 2 groups were not observed throughout a 12-month follow-up.
UUS as a measure of patient engagement was associated with changes in HbA
over the study period of the TMC system and could be used to predict improved glycemic control in diabetes self-management through mobile health interventions.

The objective of the present study was to determine the relationship between serum uric acid (SUA) level and the presence of nonalcoholic fatty liver disease (NAFLD). We analyzed data of 9,019 ...Koreans who visited a health check up center. The SUA levels of all of these subjects were within the normal range. The participants were divided into 4 groups according to the quartiles of the SUA levels for both sexes. Hepatic steatosis was diagnosed on the basis of ultrasonographic findings. Multivariate logistic regression modeling was performed across the SUA quartiles. The presence of NAFLD and metabolic abnormalities were found significantly in subjects with high-normal SUA levels. After adjustment for age, metabolic components, and the liver-function test, the adjusted odds ratio (OR, 95% CIs) for the presence of NAFLD in the subjects with the highest SUA level was 1.46 (1.17-1.82) for men and 2.13 (1.42-3.18) for women, as compared to the subjects with the lowest SUA level. Our results suggest that increased SUA concentrations, even within the normal range, are independently associated with the presence of NAFLD.
ObjectivesHDLs have many diverse functions. The goal of this study was to determine the association of HDL cholesterol (HDL-C) and apolipoprotein A-I (apoA-I) with the development of type 2 diabetes ...(T2D). In particular, this study determined the association between the ratio of HDL-C to apoA-I (HA) and incident T2D.Design and methodsA total of 27 988 subjects with impaired fasting glucose (IFG) (18 266 men and 9722 women) aged 21–91 years (mean age 40.7 years) were followed for a mean duration of 2.81 years.ResultsStudy subjects were divided into quartiles according to the baseline HA ratio. Age, male sex, current smoking, BMI, waist circumference, and high-sensitivity C-reactive protein decreased across the quartiles, and all metabolic profiles, including blood pressure, fasting glucose, insulin resistance as determined by homeostasis model assessment of insulin resistance, and lipid measurements such as total cholesterol, LDL cholesterol, non-HDL-C, and apoB, improved as the HA ratio increased. In addition, incident cases of T2D decreased as the HA ratio increased, independent of age, sex, BMI, current smoking, systolic blood pressure, HbA1c, fasting serum insulin, family history of diabetes, and serum triglyceride concentrations (HR (95% CI) of fourth quartile vs first quartile; 0.76 (0.67–0.86), P<0.0001).ConclusionsA higher HA ratio was associated with favorable metabolic profiles and a lower risk of T2D development in subjects with IFG.
Optimal vitamin D concentrations for bone health have not been determined in the Korean population. The aim of this study was to define serum 25-hydroxyvitamin D (25OHD) concentrations that indicate ...insufficiency among older Korean adults as measured by serum intact parathyroid hormone (iPTH) concentrations and bone mineral density (BMD). We analyzed data from the Fourth Korea National Health and Nutrition Examination Survey (KNHANES IV-3), which was conducted in Korea in 2009. We enrolled 1,451 men and 1,870 women aged 49 years and above. After adjusting for variables that could potentially affect serum 25(OH)D concentrations, we found that serum iPTH concentrations began to increase at serum 25(OH)D concentrations below 12.1 ng/mL (30.2 nmol/L). In addition, total-femur BMD increased until serum 25(OH)D concentrations dropped below 20.4 ng/mL (50.9 nmol/L); no significant changes were observed thereafter. Assuming that serum 25(OH)D concentrations below 12.1 and 20.4 ng/mL represent vitamin D insufficiency, the prevalences of vitamin D insufficiency were 8.7 and 50.4 % in men and 17.9 and 66.3 % in women, respectively. Serum 25(OH)D cutoff values of 12.1 ng/mL (OR = 1.26) and 20.4 ng/mL (OR = 1.54) were associated with osteoporosis (
P
< 0.01); osteoporosis was not associated with a 25(OH)D cutoff value of 30 ng/mL (75.0 nmol/L). In conclusion, serum 25(OH)D concentrations of 20 ng/mL might be sufficient for bone health in older Korean adults.
Continuous deep sedation (CDS) is an extreme form of palliative sedation to relieve refractory symptoms at the end of life. In this study, we shared our experiences with CDS and examined the clinical ...characteristics associated with survival in patients with terminal cancer who received CDS. We conducted a chart audit of 106 consecutive patients with terminal cancer who received CDS at a single hospice care unit between January 2014 and December 2016. Survival was defined as the first day of admission to the date of death. The associations between clinical characteristics and survival were presented as hazard ratios and 95% confidence intervals using a Cox proportional hazard model. The mean age of participants was 65.2 years, and 33.0% (n=35) were women. Diazepam was the most commonly administered drug, and haloperidol or lorazepam were also used if needed. One sedative was enough for a majority of the patients. Stepwise multivariate analysis identified poor functioning, a high Palliative Prognostic Index score, hyperbilirubinemia, high serum ferritin levels, and a low number of sedatives as independent poor prognostic factors. Our experiences and findings are expected to be helpful for shared decision-making and further research on palliative sedation.

Apolipoprotein B (apoB) has additional benefits over conventional lipid measurements in predicting future cardiovascular disease (CVD). We aimed to validate the clinical relevance of our equation to ...estimate apoB in a large-scale, prospective, community-based cohort study (Ansung-Ansan cohort study).A total of 9001 Korean subjects were assessed. We excluded subjects with history of CVD (n = 228), taking lipid-lowering medications (n = 51), and those whose outcome data were not available (n = 33). Finally, a total of 8713 subjects (4126 men and 4587 women) with a mean age of 52.2 years were enrolled and followed up biannually for a mean 8.1 years.At baseline, 24.9% of subjects were current smokers, 12.5% had diabetes, and 22.2% had hypertension. Incident case of CVD occurred in 600 of the study subjects (493 ischemic heart disease and 424 stroke). Independent variables included in the models were age, sex, waist circumference, current smoking, and presence of diabetes and hypertension. Both non-HDL cholesterol (HR per 1-SD 95% CI; 1.13 1.05-1.23, P = 0.002) and estimated apoB (HR per 1-SD 95% CI; 1.14 1.05-1.24, P = 0.001) were independently associated with the development of CVD; however, the LDL cholesterol level was not predictive of future CVD (HR per 1-SD 95% CI; 1.07 0.99-1.16, P = 0.08).Both non-HDL cholesterol and estimated apoB level were independently associated with the development of CVD. Because LDL cholesterol has limited value to predict incident CVD, we recommend calculating non-HDL cholesterol or apoB with our equation to predict risk of incident CVD in the general Korean population.
Studies of the efficacy of vitamin C treatment for fatigue have yielded inconsistent results. One of the reasons for this inconsistency could be the difference in delivery routes. Therefore, we ...planned a clinical trial with intravenous vitamin C administration.
We evaluated the effect of intravenous vitamin C on fatigue in office workers. A group of 141 healthy volunteers, aged 20 to 49 years participated in this randomized, double-blind, controlled clinical trial. The trial group received 10 grams of vitamin C with normal saline intravenously, while the placebo group received normal saline only. Since vitamin C is a well-known antioxidant, oxidative stress was measured. Fatigue score, oxidative stress, and plasma vitamin C levels were measured before intervention, and again two hours and one day after intervention. Adverse events were monitored.
The fatigue scores measured at two hours after intervention and one day after intervention were significantly different between the two groups (p = 0.004); fatigue scores decreased in the vitamin C group after two hours and remained lower for one day. Trial also led to higher plasma vitamin C levels and lower oxidative stress compared to the placebo group (p < 0.001, p < 0.001, respectively). When data analysis was refined by dividing each group into high-baseline and low-baseline subgroups, it was observed that fatigue was reduced in the lower baseline vitamin C level group after two hours and after one day (p = 0.004). The same did not hold for the higher baseline group (p = 0.206).
Thus, intravenous vitamin C reduced fatigue at two hours, and the effect persisted for one day. There were no significant differences in adverse events between two groups. High dose intravenous vitamin C proved to be safe and effective against fatigue in this study.
The clinical trial registration of this trial is http://ClinicalTrials.govNCT00633581.

The association between atherogenic dyslipidemia (AD) and incident type 2 diabetes (T2D) in the low-risk group for T2D has not yet been determined. The aims of this study were to investigate whether ...AD, characterized by increased serum apoB and non-HDL cholesterol, could predict the development of T2D in subjects with normal glucose tolerance (NGT). A total of 84,394 subjects with NGT (48,906 men and 35,488 women), aged 20–89 years (mean age 38.4 years), were enrolled in this study and were followed for a mean duration of 3.3 years. ApoB and non-HDL cholesterol levels showed stronger associations with the development of T2D compared with conventional lipid measurements and their ratios (HR per 1-SD (95 % CI) 1.27 (1.23–1.30) and 1.27 (1.24–1.29), respectively, both
P
< 0.001). In multivariate Cox regression models, both apoB and non-HDL cholesterol were associated with the development of T2D, independent of other risk factors for T2D, fasting serum glucose, HbA1c, and conventional lipid measurements such as triglycerides and HDL cholesterol (HR per 1-SD (95 % CI) 1.16 (1.11–1.21) and 1.15 (1.11–1.19), respectively, both
P
< 0.001). However, fasting serum glucose was not associated with the development of T2D in these models. In conclusion, AD was more closely associated with the development of T2D than fasting glucose or glycated hemoglobin in subjects with NGT.
