Cerebral visual impairment (CVI) is recognized as the most common cause of visual impairment in children in high-income countries. It refers to a heterogeneous group of visual processing deficits of cerebral origin that cannot be explained by ocular pathology alone. Major risk factors include prematurity, perinatal brain injury, and structural abnormalities of the developing brain. The terminology has shifted from cortical to CVI to reflect involvement of the entire visual network, including both primary and associative pathways. The term ‘cerebral visual disorders’ has been proposed to describe a broader range of visuoperceptual dysfunction. Clinically, CVI is characterized by inconsistent visual behaviors, including impaired visual attention, difficulty processing complex visual scenes, and delayed visual responses, often despite relatively preserved visual acuity. Diagnosis is clinical and multidisciplinary, requiring exclusion of ocular causes and assessment of functional vision. Neuroimaging may support etiological classification, but is not definitive for diagnosis. Early identification is important, as timely intervention is associated with improved visual and developmental outcomes. Parent-reported questionnaires serve as useful screening tools in early childhood, and the Korean parental questionnaire for children younger than 72 months provides an age-appropriate example. In this mini-review, management is framed around visual habilitation and environmental modification tailored to the child’s visual profile. Although prognosis varies, early recognition and targeted support can improve functional vision and overall quality of life.

Background/Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a significant risk factor for cardiovascular disease. This study aimed to evaluate differences in carotid atherosclerosis and coronary artery disease severity according to MASLD subtypes using general health screening data from multiple tertiary hospitals. Methods: A total of 3,466 subjects who underwent health check-ups including abdominal ultrasound, carotid ultrasound, and cardiac computed tomography were analyzed. Participants were categorized into non-SLD, MASLD, metabolic dysfunction-associated alcohol-relat-ed liver disease (MetALD), and alcohol-related liver disease. Carotid plaque prevalence and coronary artery stenosis severity were compared across groups and stratified by fibrosis stage using the Fibrosis-4 index (FIB-4). Results: Patients with MASLD and MetALD showed a significantly higher prevalence of carotid plaques compared with the non-SLD group. The severity of coronary artery stenosis was also greater in MASLD and MetALD, particularly among those with advanced fibrosis (FIB-4 ≥2.67). Conclusions MASLD and MetALD are associated with increased burden of systemic atherosclerosis and coronary artery disease, especially in patients with advanced fibrosis. These findings highlight the importance of cardiovascular risk assessment in individuals with MASLD and its subtypes.

Background: and PurposeWe aimed to determine the effect of demographic factors on cortical thickness and brain glucose metabolism in healthy aging subjects. Methods: The following tests were performed on 71 subjects with normal cognition: neurological examination, 3-tesla magnetic resonance imaging, 18F-fluorodeoxyglucose positron-emission tomography, and neuropsychological tests. Cortical thickness and brain metabolism were measured using vertex- and voxelwise analyses, respectively. General linear models (GLMs) were used to determine the effects of age, sex, and education on cortical thickness and brain glucose metabolism. The effects of mean lobar cortical thickness and mean lobar metabolism on neuropsychological test scores were evaluated using GLMs after controlling for age, sex, and education. The intracranial volume (ICV) was further included as a predictor or covariate for the cortical thickness analyses. Results: Age was negatively correlated with the mean cortical thickness in all lobes (frontal and parietal lobes, p=0.001; temporal and occipital lobes, p<0.001) and with the mean temporal metabolism (p=0.005). Education was not associated with cortical thickness or brain metabolism in any lobe. Male subjects had a lower mean parietal metabolism than did female subjects (p<0.001), while their mean cortical thicknesses were comparable. ICV was positively correlated with mean cortical thickness in the frontal (p=0.016), temporal (p=0.009), and occipital (p=0.007) lobes. The mean lobar cortical thickness was not associated with cognition scores, while the mean temporal metabolism was positively correlated with verbal memory test scores. Conclusions Age and sex affect cortical thickness and brain glucose metabolism in different ways. Demographic factors must therefore be considered in analyses of cortical thickness and brain metabolism.

Background: and Purpose This study aimed to determine the neuropsychological differences between patients with early-stage Alzheimer’s disease (AD) and dementia with Lewy bodies (DLB) with a Clinical Dementia Rating (CDR) score of ≤1. Methods: We examined 168 patients with AD (126 with CDR score=0.5, 42 with CDR score=1) and 169 patients with DLB (104 with CDR score=0.5, 65 with CDR score=1) whose diagnoses were supported by 18F-flobetaben positron-emission tomography (PET) and 18F-N-(3-fluoropropyl)-2β-carbon ethoxy-3β-(4-iodophenyl) nortropane PET. Neuropsychological test scores were compared after controlling for age, sex, and education duration. Using a cutoff motor score on the Unified Parkinson’s Disease Rating Scale of 20, patients with AD were further divided into AD with parkinsonism (ADP+ , n=86) and AD without parkinsonism (ADP− , n=82). Results: At CDR scores of both 0.5 and 1, the DLB group had lower scores on the attention (digit-span forward at CDR score=0.5 and backward at CDR score=1), visuospatial, and executive (color reading Stroop test at CDR score=0.5 and phonemic fluency test, Stroop tests, and digit symbol coding at CDR score=1) tests than the AD group, but higher scores on the memory tests. The ADP− and ADP+ subgroups had comparable scores on most neuropsychological tests, but the ADP+ subgroup had lower scores on the color reading Stroop test. Conclusions Patients with DLB had worse attention, visuospatial, and executive functions but better memory function than patients with AD. Parkinsonism was not uncommon in the patients with AD and could be related to attention and executive dysfunction.

Background: A considerable proportion of patients warranting total knee arthroplasty (TKA) have night pain, neuropathic pain, and/or depressive disorder, which may not be resolved by TKA. This prospective, longitudinal cohort study aimed to document the prevalence of night pain, neuropathic pain, and depressive disorder in patients with advanced knee osteoarthritis undergoing TKA and to determine whether the specific coexisting pain and/or disorder at the time of TKA adversely affected postoperative outcomes. Methods: In this study, 148 patients undergoing TKA were longitudinally evaluated. The presence of night pain, neuropathic pain (determined using Douleur Neuropathique 4 [DN4]) and depressive disorder (determined using the Patient Health Questionnaire-9 [PHQ-9]) was determined before and 6 weeks, 3 months and 1 year after TKA. In addition, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and EuroQol-5 Dimension (EQ-5D) scores were assessed before and 1 year after TKA. Potential associations of night pain, neuropathic pain, and/or depressive disorder with pre- and postoperative WOMAC and EQ-5D scores were examined in subgroup analyses. Results: Preoperatively, 72% (n = 106) of patients reported night pain, and the prevalences of neuropathic pain and depressive disorder were 15% and 17%, respectively. Preoperatively, compared with patients without night pain, those with night pain had significantly poorer preoperative WOMAC scores, but no significant difference was seen between groups 1 year after TKA. Preoperatively, the WOMAC, EQ-5D, and EQ-5D health scores of patients with neuropathic pain were not significantly different from those of patients without neuropathic pain, and there was no difference in clinical outcome scores 1 year after TKA between these groups. Preoperatively, the patients with depressive disorder showed significantly poorer preoperative WOMAC, EQ-5D, and EQ-5D health scores than those without depressive disorder, but no significant differences in scores were observed 1 year after TKA between these groups. Conclusion This study revealed a considerable prevalence of night pain, neuropathic pain, and depressive disorder in patients undergoing TKA and that patients with these specific conditions reported poorer functional and quality of life scores preoperatively. However, such adverse effects disappeared after TKA. Our study findings suggest that TKA can provide satisfactory outcomes for patients with these specific conditions.

Background: Osteoarthritis (OA) and osteoporosis (OP) are the 2 most common bone disorders associated with aging. We can simply assume that older patients have a higher incidence of OA and OP with more severity. Although several papers have conducted studies on the relationship between OA and OP, none of them has demonstrated a conclusive link. In this study, we used radiological knee OA and bone mineral density (BMD; T-score of the total hip and lumbar spine) to analyze the incidence of OA and OP in a large population. We aimed to determine the relationship between OA and OP and investigate the associated risk factors. Methods: This cross-sectional study used data extracted from the 2010–2012 Korea National Health and Nutrition Examination Survey. We evaluated a total of 4,250 participants aged ≥ 50 years who underwent knee radiography and dual-energy X-ray absorptiometry and their laboratory results. The relationship between radiological knee OA and BMD was assessed. The generalized linear model was used to evaluate the relationship between BMD and Kellgren-Lawrence (KL) grade. Results: The higher KL grade was associated with older age, higher body mass index (BMI), female sex, and lower hemoglobin level (p < 0.001). No significant association was found between OA and the following variables: white blood cell, platelet, total cholesterol, vitamin D, alkaline phosphatase, parathyroid hormone, hypertension, diabetes, asthma, dyslipidemia, smoking status, alcohol consumption, and regular exercise (p > 0.05). After adjusting for confounding factors (age, BMI, diabetes, hypertension, smoking, and alcohol consumption), the average T-scores of total hip and lumbar spine were the highest in the mild OA group with KL grade 2 (–0.22 ± 1.08 and –0.89 ± 1.46, respectively,p < 0.001). The average T-scores of the total hip and lumbar spine significantly decreased as OA progressed from moderate (KL grade 3; –0.49 ± 1.05 and –1.33 ± 1.38, respectively, p < 0.001) to severe (KL grade 4; –0.73 ± 1.13 and –1.74 ± 1.75, respectively, p < 0.001). T-scores of the moderate-to-severe OA group were significantly lower than those of the non-OA group (KL grades 0 and 1, p < 0.001). Conclusions Compared with the non-OA group, BMD (T-scores of the total hip and lumbar spine) was higher in the mild OA group and lower in the moderate-to-severe OA group.

Objectives: : This study aimed to characteristic the systolic blood pressure (SBP), diastolic pressure, pulse pressure, glucose, creatine, and lipid profile. This study also aimed to investigate the prevalence of hypertension and the relationship between hypertension and the lipid profile in Uzbekistan. Methods: The subjects consisted of 58 Uzbekistan subjects recruited from Ewha Medical Care patients. Blood samples were collected from the patients for the lipid profile and random glucose and creatinine levels. Paired t tests were used for the group means and a chi-square or Fisher’s exact test for categorical variables. A multiple logistic regression analysis was performed. Results: Among the 58 patients constituting the baseline population, hypertension developed in 42 patients. Among them, the triglyceride (TG) level was significantly higher in the hypertension group than normal group (173.19 vs. 127.06 mg/dL, P=0.014). The SBP had a positive correlation with the TG (r=0.979, P<0.01) and creatinine (r=0.002, P<0.05) levels and also, the pulse pressure had a positive correlation with the cholesterol level (r=0.539, P<0.05). A multivariate analysis (adjusted for age and sex) indicated that there was a positive correlation between the SBP and TG level (r=0.941, P<0.05). Conclusion There was a positive correlation between the SBP and TG level in the Uzbekistan population according to this study.

Objective: Suicide is a huge nationwide problem that incurs a lot of socio-economic costs. Suicide also inflicts severe distress on the people left behind. The government of the Republic of Korea has been making many policy efforts to reduce suicide rate. The gatekeeper program, ‘Suicide CARE’, is one of the meaningful modalities for preventing suicide. Methods: Multidisciplinary research team collaborated to update the ‘Suicide CARE’ to version 2.0. Results: In the ‘Introductory part’, the authors have the time to think about the necessity and significance of the program before conducting full-scale gatekeeper training. In the ‘Careful observation’ part, trainees learn how to understand and recognize the various linguistic, behavioral, and situational signals that a person shows before committing suicide. In the ‘Active listening’ part, trainees learn how to ask suicide with a value-neutral attitude as well listening empathetically. In the ‘Risk evaluation and Expert referral’ part, trainees learn intervening strategies to identify a person’s suicidal intention, plan, and past suicide attempts, and connect the person to appropriate institutes or services. Conclusion Subsequent studies should be conducted to verify the efficacy of the gatekeeper program.
