Objective: While the association between depression and frailty in the elderly population has been investigated, the psychological factors that mediate such a relationship remain unknown. The identification of psychological factors in interventions for depression treatment in the elderly may assist in the treatment and care. We aimed to explore the mediating effects of anger, anxiety, and resilience on the link between frailty and depression symptoms in patients with late-life depression. Methods: A sample of 203 older adults completed questionnaires that assessed depression, anger, resilience, and anxiety.To measure frailty, participants were evaluated using a self-rated health questionnaire, weight-adjusted waist index related to sarcopenia, and weight-adjusted handgrip strength to evaluate weakness. A mediation model was tested, hypothesizing that anger, anxiety, and resilience would partially mediate the strength of the frailty-depression link in the elderly. Results: Only self-rated health showed a significant association with depressive symptoms in late-life depression. Our study demonstrated that frailty has both direct and indirect associations with depression, mediated by anger, resilience, and anxiety. Conclusion Given that anger, resilience, and anxiety influence the link between self-rated health and depression, interventions that lead to increased resilience and decreased anger and anxiety may be promising to reduce depressive symptoms in older adults with depression.

Objective: This study was performed to evaluate the efficacy and safety of lurasidone (160 mg/day) compared to quetiapine XR (QXR; 600 mg/day) in the treatment of acutely psychotic patients with schizophrenia. Methods: Patients were randomly assigned to 6 weeks of double-blind treatment with lurasidone 160 mg/day (n=105) or QXR 600 mg/day (n=105). Primary efficacy measure was the change from baseline to week 6 in Positive and Negative Syndrome Scale (PANSS) total score and Clinical Global Impressions severity (CGI-S) score. Adverse events, body measurements, and laboratory parameters were assessed. Results: Lurasidone demonstrated non-inferiority to QXR on the PANSS total score. Adjusted mean±standard error change at week 6 on the PANSS total score was -26.42±2.02 and -27.33±2.01 in the lurasidone and QXR group, respectively. The mean difference score was -0.91 (95% confidence interval -6.35–4.53). The lurasidone group showed a greater reduction in PANSS total and negative subscale on week 1 and a greater reduction in end-point CGI-S score compared to the QXR group. Body weight, body mass index, and waist circumference in the lurasidone group were reduced, with significantly lower mean change compared to QXR. Endpoint changes in glucose, cholesterol, triglycerides, and low-density lipoprotein levels were also significantly lower. The most common adverse drug reactions with lurasidone were akathisia and nausea. Conclusion Lurasidone 160 mg/day was found to be non-inferior to QXR 600 mg/day in the treatment of schizophrenia with comparable efficacy and tolerability. Adverse effects of lurasidone were generally tolerable, and beneficial effects on metabolic parameters can be expected.

Background/Aims: The etiology of irritable bowel syndrome (IBS) is associated with intestinal mucosal barrier damage. However, changes in the tight junction (TJ) proteins in IBS have not been fully elucidated. This study aimed to evaluate TJ protein changes in IBS patients and the relationship between aging and disease severity. Methods: Thirty-six patients with IBS fulfilling the Rome IV criteria and twenty-four controls were included. To evaluate the change of TJ in the colonic mucosa, quantitative reverse transcription polymerase chain reaction, western blot, and immunohistochemistry (IHC) were performed, respectively. Results: The entire IBS group (n = 36) exhibited decreased levels of claudin-1 and -2 mRNA compared to the control group (n = 24), with statistical significance (p < 0.05). Additionally, in western blot analyses, both claudin-1 and ZO-1 levels were significantly reduced in the IBS group compared to the control group (n = 24) (p < 0.05). IHC analysis further revealed that ZO-1 expression was significantly lower in the IBS group than in the control group (p < 0.001). This trend of reduced ZO-1 expression was also observed in the moderate-to-severe IBS subgroup (p < 0.001). Significantly, ZO-1 expression was notably lower in both the young- (p = 0.036) and old-aged (p = 0.039) IBS groups compared to their respective age-matched control groups. Subtype analysis indicated a more pronounced decrease in ZO-1 expression with advancing age. Conclusions ZO-1 expression was especially decreased in the aged IBS group. These results suggest that ZO-1 might be the prominent TJ protein causing IBS in the aging population.

Objective: Anxious depression is associated with greater chronicity, higher severity of symptoms, more severe functional impairment, and poor response to drug treatment. However, evidence for first-choice antidepressants in patients with anxious depression is limited. This study aimed to compare the efficacy and safety of escitalopram, desvenlafaxine, and vortioxetine in the acute treatment of anxious depression. Methods: Patients (n = 124) with major depressive disorder and high levels of anxiety were randomly assigned to an escitalopram treatment group (n = 42), desvenlafaxine treatment group (n = 40), or vortioxetine treatment group (n = 42) in a 6-week randomized rater-blinded head-to-head comparative trial. Changes in overall depressive and anxiety symptoms were assessed using the 17-item Hamilton Depression Rating Scale (HAMD) and Hamilton Anxiety Rating Scale (HAMA), respectively. Results: Patients demonstrated similar baseline-to-endpoint improvement in scores and similar response and remission rates for HAMD and HAMA. Analysis of the individual HAMD items revealed that desvenlafaxine significantly reduced anxiety somatic scores (p= 0.013) and hypochondriasis scores (p = 0.014) compared to escitalopram. With respect to the individual HAMA items, desvenlafaxine treatment showed significantly lower scores for respiratory symptoms (p = 0.013) than escitalopram treatment and cardiovascular symptoms (p = 0.005) than vortioxetine treatment. The treatments were well tolerated, with no significant differences. Conclusion Our results indicated no significant differences in the efficacy and tolerability of escitalopram, desvenlafaxine, and vortioxetine in this subtype of patients with anxious depression during the acute phase of treatment.

Objective: This study aimed to compare the efficacy and safety of escitalopram, vortioxetine, and desvenlafaxine for acute treatment of major depressive disorder (MDD) with cognitive complaint (CC). Methods: A total of 129 patients with MDD who also complained of CC were randomized evenly to either escitalopram, vortioxetine, or desvenlafaxine group and underwent a multi-center, six-week, rater-blinded, and head-to-head comparative trial. Differences in depressive symptoms following treatment were measured using the Hamilton Depression Rating Scale (HAMD) and the Montgomery-Åsberg Depression Rating Scale (MADRS). Subjective cognitive function and the presence of adverse events were assessed. Results: The three antidepressant treatment groups did not show significant differences in the improvement of depressive symptoms as measured by HAMD and MADRS. Desvenlafaxine treatment was associated with a superior treatment response rate in depressive symptoms compared to vortioxetine or escitalopram treatment. However, no significant differences were found in the remission rate of depressive symptoms. The three antidepressant treatment groups did not show significant differences in the improvement of CC. Adverse profiles of each treatment group were tolerable, with no significant differences. Conclusion In acute antidepressant treatment for MDD with CC, escitalopram, vortioxetine, and desvenlafaxine presented similar efficacy in relief of depressive symptoms; however, desvenlafaxine was associated with a superior treatment. Further studies are needed to confirm these results by investigating the therapeutic efficacy and safety profile of long-term antidepressant treatment of MDD with CC (Clinical Trial Registry, http://cris.nih.go.kr/cris/en/: KCT0002173).

Objective: Many patients with major depressive disorder (MDD) suffer from residual symptoms without achieving remission. However, pharmacologic options for residual symptoms of MDD have been limited. This study aimed to investigate benefit of aripiprazole augmentation in the treatment of residual symptoms in the patients with partially remitted MDD. Methods: We retrospectively analyzed the 8-week medical records of the patients. The enrolled patients did respond to treatment of antidepressant but were not remitted. The range of 17-item Hamilton Depression Rating Scale (HAMD) total score of the subjects were 8 to 15 points. All patients were currently taking antidepressants when they started aripiprazole. The primary endpoint was the mean change of Clinically Useful Depression Outcome Scale (CUDOS).Secondary endpoint measures were HAMD, Clinical Global Impression-severity (CGI-S) scores, Patient Health Questionnaire-15 (PHQ-15), Beck Anxiety Inventory (BAI), Perceived Deficit Questionnaire-depression (PDQ-D), Sheehan Disability Scale (SDS) and General Health Questionnaire/Quality of Life-12 (GHQ/QL-12). Results: A total of 134 medical records were analyzed. The changes of CUDOS, HAMD, CGI-S, BAI, PHQ-15, PDQ-D, SDS and GHQ/QL-12 from baseline to the endpoint were −7.93, −3.29, −0.80, −4.02, −2.05, −4.35, −4.77 and −2.82, respectively (all p ＜ 0.001). At the endpoint, the newly remitted subjects rate by HAMD score criteria were approximately 46%. Conclusion Our preliminary findings have presented the effectiveness of aripiprazole augmentation for residual symptoms of partially remitted MDD patients in routine practice. This study assures subsequent well-controlled studies of the possibility of generalizing the above promising outcome in the future.

Background: The worldwide incidence of renal disease diagnosed by a kidney biopsy varies with age, race, sex, and region. Owing to a lack of studies and limited research resources for this disease in Korea, we investigated renal disease patterns by analyzing data from kidney biopsies performed over 13 years in a university-based teaching hospital in Korea. Methods: Among 2,053 kidney biopsies performed from 2001 to 2013 at Kyungpook National University Hospital, 1,924 were retrospectively analyzed for histopathologic, demographic, and clinical data as well as laboratory results. Results: Among the 1,924 studied kidney biopsies, 1,078 were males (56.0%) and the mean age was 37.7 ± 16.5 years. Asymptomatic urinary abnormalities were the most common clinical manifestation (62.5%). Immunoglobulin A nephropathy (IgAN) was the most common primary glomerular disease (37.4%), followed by minimal change disease (MCD), membranous nephropathy (MN), focal segmental glomerulonephritis and crescentic glomerulonephritis. Secondary glomerular diseases accounted for 10.3% of the total biopsies, with lupus nephritis being the most common (4.6%) followed by Henoch-Schönlein purpura nephritis and diabetic nephropathy. The most common cause of nephrotic syndrome was MCD (42.1%) followed by MN. Among patients seropositive for hepatitis B or C, IgAN (28.3% and 21.4%, respectively) was the most common cause. Conclusion IgAN and lupus nephritis were the most common primary and secondary glomerular diseases, respectively. Race, region, and practice patterns may affect renal disease patterns in different cohorts.

BACKGROUND: Systemic immunomodulatory treatment is actively recommended in the treatment for moderate to severe atopic dermatitis (AD) patients. However, consensus criteria for the classification of AD severity or treatment refractoriness have not been established yet. OBJECTIVE: To establish consensus criteria on the definition of severity classification and treatment refractoriness of AD to provide a basis for proper treatment strategy. METHODS: The Korean Atopic Dermatitis Association (KADA) comprised a task force team to establish a definition of moderate to severe AD. A draft of definition of moderate to severe AD was made on the basis of evidence. The recommendation was confirmed by KADA members through a web-based survey. RESULTS: KADA approved that AD with 16≤eczema area and severity index (EASI)<23 should be basically defined as moderate AD whereas AD with EASI score ≥23 should be considered as severe AD. They agreed that it would be reasonable to raise the severity level if patient's daytime or nighttime pruritus numerical rating scale is equal to or higher than 7 (≥7) or dermatology life quality index score exceeds 10. AD patients who do not reach EASI 50 after appropriate treatment for three months should be considered as a non-responder. Patients with recurrence (EASI ≥16) within three months after cessation of treatment should be considered as a recurrent AD. CONCLUSION: KADA built a consensus of definition of moderate and severe AD and treatment-refractoriness. These guidelines are expected to help physicians determine proper treatment options in need.
