ABSTRACT
Purpose@#This study aimed to evaluate angiographic and contrast enhancement (CE) patterns on three-dimensional (3D) black blood (BB) contrast-enhanced MRI in patients with acute medulla infarction. @*Materials and Methods@#From January 2020 to August 2021, we retrospectively analyzed stroke 3D BB contrast-enhanced magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) findings of patients visiting the emergency room for symptom evaluation of acute medulla infarction. In total, 28 patients with acute medulla infarction were enrolled in this study. Four types of 3D BB contrast-enhanced MRI and MRA were classified as follows: 1=unilateral contrast-enhanced vertebral artery (VA)+no visualization of VA on MRA; 2=unilateral enhanced VA+hypoplastic VA; 3=no enhanced VA+unilateral complete occlusion of VA; 4=no enhanced VA+normal VA (including hypoplasia) on MRA. @*Results@#Of the 28 patients with acute medulla infarction, 7 (25.0%) showed delayed positive findings after 24 hours on diffusion-weighted imaging (DWI). Of these patients, 19 (67.9%) showed CE of the unilateral VA on 3D BB contrast-enhanced MRI (type 1 and 2). Of the 19 patients with CE of VA on 3D BB contrast-enhanced MRI, 18 showed no visualization of enhanced VA on MRA (type 1), and 1 showed hypoplastic VA. Of the 7 patients with delayed positive findings on DWI, 5 showed CE of the unilateral VA and no visualization of the enhanced VA on MRA (type 1). Symptom onset to door time or initial MR check time was significantly shorter in the groups with delayed positive findings on DWI (P<0.05). @*Conclusion@#Unilateral CE on 3D BB contrast-enhanced MRI and no visualization of the VA on MRA are related to the recent occlusion of the distal VA. These findings suggest that the recent occlusion of the distal VA is related to acute medulla infarction, including delayed visualization on DWI.
ABSTRACT
BACKGROUND: Many studies have assessed the relationship between each nutrient element and depression independently, but few have assessed the effect of dietary intake on depression, as diagnosed using the Patient Health Questionnaire (PHQ-9). This study investigated the relationship between dietary intake and depression, which was diagnosed using the PHQ-9.METHODS: This study used the second data set (2014) from the sixth Korea National Health and Nutrition Examination Survey (KNHNES). Our analysis included 5,897 persons who answered the PHQ-9, aged 20 to 60 years. They were categorized into either a male or female group, which were then subdivided into a depression group of patients who were diagnosed using the PHQ-9, and those without depression (control group). The patients' dietary intakes were obtained using the 24-hr recollection method in KNHNES. The relationship between dietary intake and depression was investigated for each group.RESULTS: In males, dietary intake was not associated with depression in both groups, except in relation to carotene. While in females, the depression group had lower fiber and vitamin C dietary intake than the control group (fiber P=0.015, vitamin C P=0.020). The dietary intakes of all other nutrients had no associations between the depression and control groups, in both males and females.CONCLUSION: According to our results, low dietary intake of fiber and vitamin C may be associated with depression in females. These results suggest that a diet regimen that includes fiber and vitamin C may help prevent and reduce depression in females.

OBJECTIVES: Metabolic syndrome and depression are interconnected disorders. Although many studies have assessed the association between dietary intake and each disorder independently, few studies have examined the association between depression and dietary intake in patients with metabolic syndrome. Our study examined the association between depression and dietary intake in adults with metabolic syndrome. METHODS: We analyzed the second data set (2014) from the sixth KNHNES. Of the patients with metabolic syndrome, the final study population comprised 1,334 patients, aged 20 to 60 years, with metabolic syndrome as defined by KNHNES and depression diagnosed by a physician. We examined the patients??dietary intake obtained using the 24-h recollection method in KNHNES. RESULTS: Depression group had a lower niacin dietary intake than those without depression in both male and female (male P=0.047, female P=0.025). None of the other components had any association between depression group and those without depression group in both male and female. CONCLUSIONS: This study demonstrates that a low dietary intake of niacin may be related to the depression in patients with metabolic syndrome. The results indicate that it is worthwhile to evaluate the nutritional status in patients who have been diagnosed with both metabolic syndrome and depression.
