The prevalence of postpartum depression (PPD) in Asia is reported to range from 13.53% to 22.31%. However, there remains a gap in the identification of PPD, particularly regarding cultural cutoff points. Therefore, the purpose of this scoping review was to determine the prevalence and associated factors of PPD in Eastern, South-eastern, Western, and Southern Asian countries and analyze the cutoff points of the Edinburgh Postnatal Depression Scale (EPDS) used across these countries. Following Arksey and O'Malley’s five-step scoping review framework, the population was defined as mothers, the concept as the EPDS, and the context as the Asian region. A literature search was conducted using PubMed, Embase, CINAHL, PsycINFO, and Web of Science. The data analysis focused on demographic characteristics, EPDS cutoffs and features, PPD prevalence, and its associated factors. Nineteen studies were selected. Most countries used translated versions of the EPDS with demonstrated reliability and validity. The cutoff scores varied, with most using scores of 10 or higher. The prevalence of PPD ranged from 5.1% to 78.7%. Key associated factors for PPD included cultural factors such as relationships with in-laws and preferences for the newborn’s sex. To improve the accuracy of PPD screening in Asia, the EPDS should be used consistently, and appropriate cutoff criteria must be established. In addition, prevention strategies and programs that reflect the cultural characteristics and social context of Asia need to be developed for the early detection and prevention of PPD.

Colon tumors develop more frequently in male than in female. Nuclear factor erythroid 2-related factor 2 (Nrf2) plays differential roles in the stage of tumorigenesis. The purpose of this study was to investigate the role of Nrf2 on colitis-associated tumorigenesis using Nrf2 knockout (KO) female mice. Azoxymethane (AOM) and dextran sulfate sodium (DSS)-treated wild-type (WT) and Nrf2 KO female mice were sacrificed at week 2 and 16 after AOM injection. Severity of colitis, tumor incidence, and levels of inflammatory mediators were evaluated in AOM/DSS-treated WT and Nrf2 KO mice. Furthermore, qRT-PCR, Western blot abnalysis, and ELISA were performed in colon tissues. At week 2, AOM/DSS-induced colon tissue damages were significantly greater in Nrf2 KO than in WT mice. At week 16, tumor numbers (> 2 mm size) were significantly lower in both the proximal and distal colon in Nrf2 KO compared to WT. The overall incidences of adenoma/cancer of the proximal colon and submucosal invasive cancer of the distal colon were reduced by Nrf2 KO. The mRNA and protein expression levels of NF-κB-related mediators (i.e., iNOS and COX-2) and Nrf2-related antioxidants (i.e., heme oxygenase-1 and glutamate-cysteine ligase catalytic subunit) were significantly lower in the Nrf2 KO than in WT mice. Interestingly, the protein level of 15-hydroxyprostaglandin dehydrogenase (15-PGDH) was higher in AOM/DSS-treated Nrf2 KO than in WT mice. Our results support the oncogenic effect of Nrf2 in the later stage of carcinogenesis and upregulation of tumor suppressor 15-PGDH might contribute to the repression of colitis-associated tumorigenesis in Nrf2 KO female mice.

Objective: Unlike common acute urinary tract infections, obstructive urinary tract infections caused by urinary calculus can be fatal because they can progress to sepsis and cause shock or disseminated intravascular coagulation. The evidence of patients with obstructive urinary tract infections caused by urinary tract stones visiting the emergency center is still lacking. Methods: Seventy-seven patients who visited the emergency room with obstructive urinary tract infections caused by urinary calculus from January 2016 to December 2018 were enrolled in this study and divided into two groups: sepsis group and non-sepsis group. Results: The lymphocyte count, platelet count, neutrophil-lymphocyte ratio, serum creatinine, and C-reactive protein were significantly different in the sepsis-positive and negative groups. Percutaneous nephrostomy was also significantly higher in the sepsis-positive group. The area under the receiver operating characteristic curve was calculated to evaluate the ability of the neutrophil-lymphocyte ratio and platelet-lymphocyte ratio to predict a septic urinary tract infection. The neutrophil-lymphocyte ratio and platelet-lymphocyte ratio were 0.659 and 0.550, respectively. Multivariate logistic regression analysis showed that diabetic patients, percutaneous nephrostomy, and serum creatinine were associated with septic obstructive urinary tract infection. Conclusion In patients with an obstructive urinary tract infection who were referred to the emergency center, diabetic patients and those with high blood urea nitrogen and creatinine levels are at high risk of sepsis. In such cases, rapid diagnosis and treatment, such as percutaneous nephrostomy, are necessary.

PURPOSE: This study examined the immunological activity and optimized the mixture conditions of Sargassum horneri (S. horneri) extracts in vitro and in vivo models.METHODS: S. horneri was extracted using three different methods: hot water extraction (HWE), 50% ethanol extraction (EE), and supercritical fluid extraction (SFE). Splenocyte proliferation and cytokine production (Interleukin-2 and Interferon-γ) were measured using a WST-1 assay and enzyme-linked immunosorbent assay, respectively. The levels of nitric oxide and T cell activation production were measured using a Griess assay and flow cytometry, respectively. The natural killer (NK) cell activity was determined using an EZ-LDH kit.RESULTS: Among the three different types of extracts, HWE showed the highest levels of splenocyte proliferation and cytokine production in vitro. In the animal model, three different types of extracts were administrated for 14 days (once/day) at 50 and 100 mg/kg body weight. HWE and SFE showed a high level of splenocyte proliferation and cytokine production in the with and without mitogen-treated groups, whereas EE administration did not induce the splenocyte activation. When RAW264.7 macrophage cells were treated with different mixtures (HWE with 5, 10, 15, 20% of SFE) to determine the optimal mixture ratio of HWE and SFE, the levels of nitric oxide and cytokine production increased strongly in the HWE with 5% and 10% of SFE containing group. In the animal model, HWE with 5% and 10% of SFE mixture administration increased the levels of splenocyte proliferation, cytokine production, and activated CD4⁺ cell population significantly, with the highest level observed in the HWE with 5% of SFE group. Moreover, the NK cell activity was increased significantly in the HWE with 5% of SFE mixture-treated group compared to the control group.CONCLUSION: The optimal mixture condition of S. horneri with immune-enhancing activity is the HWE with 5% of SFE mixture. These results confirmed that the extracts of S. horneri and its mixtures are potential candidate materials for immune enhancement.

OBJECTIVE: Syncope is mostly benign, but it can also be caused by a life-threatening situation. In Korea, no studies have investigated application of the Canadian Syncope Risk Score (CSRS) to patients with syncope; therefore, this study was started to evaluate the usefulness of CSRS. METHODS: A total of 222 patients who visited the emergency room with syncope for one year from January 2016 to December 2016 were enrolled in this study. Patients were divided into two groups, a serious adverse events (SAE) group and a non-serious adverse events group. The scores of the nine CSRS variables were added and the CSRS was then calculated after the addition. RESULTS: The CSRS score for patients with SAE ranged from 0 to 8. The CSRS score was 18.6%, 31.7%, 55.6%, and 58.8% for 0, 1, 2, and 3, respectively. In the case of CSRS 0 and 1, 17 patients (81.0%) and 11 patients (84.6%) were non-cardiac. In the case of CSRS 2, 7 were non-cardiac (70.0%). In the case of CSRS 3, 6 cases (60.0%) were cardiogenic and 4 cases (40.0%) were non-cardiogenic. The area under the receiver operating characteristic curve of CSRS to predict SAE was 0.71. Setting the CSRS cutoff value to 0, we found that sensitivity and specificity of predicting SAE was 67.19% and 67.09%, respectively. CONCLUSION: CSRS may be difficult to predict for acute intracranial disease or acute hemorrhagic disease requiring transfusion; therefore, it is necessary to supplement it further.
