Limited data exist regarding the real-world practices and clinical outcomes in patients with ischemic heart failure with reduced left ventricular ejection fractions (LVEFs).Using nationwide registry data from South Korea, we aimed to investigate long-term outcomes and clinical practices, especially implantable cardioverter defibrillators (ICDs) implantation, in patients with reduced LVEFs at least 40 days after acute myocardial infarction (AMI). Of 13,056 patients with AMI between 2011 and 2015, we analyzed 350 (median age, 66 years [interquartile range, 56-75]) who had LVEFs <40% on follow-up transthoracic echocardiogram 40 days after the index event. The primary outcome was cardiac-cause mortality at 3 years. Secondary outcomes comprised major cardiovascular events as well as outcomes defined by the use of ICDs, cardiac resynchronization therapy defibrillators (CRT-Ds), and electrophysiology studies. Among 350 patients, 39 (11.1%) died from cardiac causes during 3 years of follow-up. Eleven (3.1%) were hospitalized for ventricular tachycardia. The rate of ICD or CRT-D implantation up to 3 years was 5.7% (20/350). Cox time-to-event analysis revealed older age, LVEF <30%, diabetes mellitus, and previous MI or revascularization as positively associated with cardiac death, whereas the use of statins and body weight <67 kg were negatively associated. This nationwide Korean registry demonstrated that only 5.7% of patients who had reduced LVEFs after 40 days of AMI underwent ICD implantations over 3 years. Considering the high mortality, concerted efforts are needed to improve clinical outcomes for patients who may have been candidates for ICD implantation.

Objectives: We mapped trends in studies on dietary behaviors, nutritional status, and nutrition-related education among individuals with developmental disabilities in Korea over the past decade to identify research gaps and inform future research and policy development. Methods: A scoping review was conducted using three major Korean academic databases (RISS, KISS, and DBpia). Studies published between 2015 and September 2025 were identified using combinations of keywords related to developmental disabilities, dietary behavior, nutrition, and health-related interventions. Eligible studies included empirical studies and secondary research (e.g., systematic or scoping reviews) conducted in Korea that focused on dietary behaviors, nutrition, health promotion, or nutrition-related education for individuals with developmental disabilities. Thirty-six studies met our inclusion criteria and were analyzed based on study design, study population, disability type, research topic, and publication period. Results: Observational quantitative, qualitative, intervention-based experimental, and evidence synthesis accounted for 27.8%, 13.9%, 22.2%, and 36.1% of all included studies, respectively. Children and adolescents (27.8%) and adults (25.0%) were the most frequently studied populations, with limited studies focusing on professionals or teachers. Most studies targeted individuals with developmental disabilities as a combined group (61.1%), followed by those specifically targeting autism spectrum disorder. Research topics included dietary behaviors and nutritional status, nutrition-related education and interventions, health promotion, and medical or clinical issues, with many small-scale and shortterm intervention studies. Conclusion Although research on dietary and nutrition-related issues among individuals with developmental disabilities in Korea has expanded in scope and methodology, significant limitations remain. Future research should adopt longitudinal and community-based approaches, incorporate diverse populations, and strengthen policy-oriented nutrition support systems to promote sustainable health and quality of life for individuals with developmental disabilities.

With the rapid development of sequencing technologies, the detection of alternative polyadenylation (APA) in mammals has become more precise. APA precisely regulates gene expression by altering the length and position of the poly(A) tail, and is involved in various biological processes such as disease occurrence and embryonic development. The research on APA in mammals mainly focuses on the following aspects:(1) identifying APA based on transcriptome data and elucidating their characteristics; (2) investigating the relationship between APA and gene expression regulation to reveal its important role in life regulation;(3) exploring the intrinsic connections between APA and disease occurrence, embryonic development, differentiation, and other life processes to provide new perspectives and methods for disease diagnosis and treatment, as well as uncovering embryonic development regulatory mechanisms. In this review, the classification, mechanisms and functions of APA were elaborated in detail and the methods for APA identifying and APA data resources based on various transcriptome data were systematically summarized. Moreover, we epitomized and provided an outlook on research on APA, emphasizing the role of sequencing technologies in driving studies on APA in mammals. In the future, with the further development of sequencing technology, the regulatory mechanisms of APA in mammals will become clearer.

Objective: This study aims to objectively evaluate turning gait parameters in Parkinson’s disease (PD) patients using 2D-RGB video-based analysis and explore their relationships with imbalance. Methods: We prospectively enrolled PD patients for clinical assessment, balance analysis and gait with 180º turning. Spatiotemporal gait parameters during turning were derived using video-based analysis and correlated with modified Hoehn and Yahr (mHY) stages and center of pressure (COP) oscillations. Results: A total of 64 PD patients were enrolled. The PD patients with higher mHY stages (≥2.5) had significantly longer turning times, greater numbers of steps, wider step bases and less variability in step length during turns. COP oscillations were positively correlated with the mean turning time on both the anterior-posterior and right-left axes. Conclusion Spatiotemporal gait parameter during turning, derived from video-based gait analysis, may represent apromising biomarker for monitoring postural instability in PD patients.

Sarcoidosis is an inflammatory condition affecting multiple systems in the body, distinguished by the presence of noncaseating granulomas. It is believed that specific exposures to external antigens in individuals with genetic predisposition lead to the development of these granulomas. When diagnosing sarcoidosis, tuberculosis (TB) is a potential alternative explanation for the symptoms. Our case describes a rare coexistence of cutaneous sarcoidosis and TB pleurisy in a 75-year-old male. He was diagnosed with cutaneous sarcoidosis on his face. During the investigation for possible involvement of other organs, pleural effusion was discovered, and it was determined to be caused by mycobacterial infection. The patient received a 6-month course of anti-TB drugs to treat the TB pleurisy, while a topical calcineurin inhibitor was applied to the cutaneous sarcoidosis. This case serves as a reminder to dermatologists that the coexistence of TB with sarcoidosis is possible, not just as a differential diagnosis.

Background: Middle-aged cancer survivors lack specific health guidelines compared to young and old cancer survivors. Their increased prevalence necessitates the establishment of tailored health guidelines. This study aimed to investigate the health-related behaviors of middle-aged cancer survivors compared to those of the general population. Methods: This cross-sectional study analyzed 17,332 adults aged 40–65 years who participated in the sixth and seventh Korea National Health and Nutrition Examination Survey (2013–2018). Data on cancer screening, alcohol consumption, smoking, physical activity, sedentary time, and dietary management were collected via self-reported questionnaires. Propensity score matching (1:5) revealed 591 middle-aged cancer survivors and 2,955 non-cancer controls. Descriptive statistics, chi-square tests, and logistic regression analyses were conducted to compare the demographic characteristics and health-related behaviors of both groups. Results: Multivariate analysis revealed that middle-aged cancer survivors were significantly less likely to consume alcohol (odds ratio [OR]: 0.64; 95% confidence interval [CI]: 0.51–0.81) and smoke (OR: 0.65; 95% CI: 0.43–0.99) and more likely to engage in aerobic physical activity (OR: 1.33; 95% CI: 1.08–1.64) and practice dietary management (OR: 1.47; 95% CI: 1.17–1.84) than the non-cancer controls. However, no significant differences in cancer screening adherence and sedentary time were observed between both groups. Conclusions Overall, this study provides fundamental data for the development of tailored health guidelines and patient education programs for cancer survivors.

Objective: As the demand for community mental health services continues to grow, the need for well-equipped and organized services has become apparent. This study aimed to optimize the roles and infrastructure of mental health services, by establishing, among other initiatives, standardized operating models. Methods: The study was conducted in multiple phases from May 12, 2021, to December 29, 2021. Stakeholders within South Korea and metropolitan mental health welfare centers were targeted, but addiction management support centers, including officials, patients, and their families, were integrated as well. A literature review and survey, focus group interviews, a Delphi survey, and expert consultation contributed to comprehensive revisions and improvements of the mental health service model. Results: The proposed model for community mental health welfare centers emphasizes the expansion of personnel and infrastructure, with a focus on severe mental illnesses and suicide prevention. The model for metropolitan mental health welfare centers delineates essential tasks in areas such as project planning and establishment, community research, and education about severe mental illnesses. The establishment of a 24-hour emergency intervention center was a crucial feature. In the integrated addiction support center model, the need to promote addiction management is defined as an essential task and the establishment of national governance for addiction policies is recommended. Conclusion This study proposed standard operating models for three types of mental health service centers. To meet the increasing need for community care, robust mental health service delivery systems are of primary importance.

Allogeneic stem cell transplantation (allo-SCT) is a salvage treatment option for patients with relapsed or refractory lymphoid malignancies. However, the clinical variables impacting outcomes in these patients remain unclear. We analyzed 58 patients who underwent allo-SCT for lymphoid malignancies, including B-cell lymphoma (BCL, n = 20), Hodgkin’s disease (n = 3), multiple myeloma (n = 9), natural killer/T-cell lymphoma (NK/TCL, n = 4), and TCL (n = 22).The median progression-free survival (PFS) was 27.4 months, while the median overall survival (OS) was 30.6 months.In univariate analysis, human leukocyte antigen (HLA) matching and complete remission status post-transplantation were associated with improved PFS and OS. However, only post-transplant response remained significant for both sur‑ vival outcomes in the multivariate analysis. Moreover, HLA matching was associated with a significantly improved PFS in patients with BCL and NK/TCL, but with better OS only in those with BCL. Complete remission after transplantation was associated with better PFS and OS in patients with BCL, NK/TCL, and TCL. Our results indicate that post-transplant response is an important prognostic indicator in allo-SCT for lymphoid malignancies and may guide clinical decisions and additional treatment.

Aim To investigate the high expression of LINC00626 in colorectal cancer,and explore the effects of LINC00626 on the proliferation,apoptosis,and drug sensitivity of colorectal cancer SW480 cells,as well as its underlying mechanisms.Methods Flu-orescence in situ hybridization(FISH)was used to de-tect the expression levels of LINC00626 in 38 colorec-tal cancer tissues and their corresponding adjacent nor-mal tissues.The JASPAR database was utilized to pre-dict co-expressed genes and their possible binding sites.Cell transfection technology was employed to knockdown LINC00626.Western blot and qRT-PCR techniques were used to verify the transfection efficien-cy.CCK-8 assay,cell apoptosis and necrosis staining,and Western blot were used to detect the changes in the proliferation,apoptosis,drug sensitivity,and ap-optotic proteins of SW480 cells,respectively.Results The FISH results indicated that LINC00626 was highly expressed in colorectal cancer tissues(P＜0.05).The expression of LINC00626 was not associat-ed with the age or gender of patients,but was related to the TNM stage and the presence of lymph node me-tastasis($ P＜0.05 $).The results of CCK-8 assay and cell apoptosis and necrosis staining showed that af-ter knockdown of LINC00626,the proliferation ability of SW480 cells decreased,the apoptosis level in-creased,and the drug resistance decreased(P＜0.05).Western blot results showed that with the de-crease in the expression level of LINC00626,the ex-pression of caspase-3 protein decreased,the expression of cleaved caspase-3 protein increased,and the expres-sion of Bcl-2 protein decreased(P＜0.05).Conclu-sions LINC00626 is highly expressed in colorectal cancer and is associated with the TNM stage and the presence of lymph node metastasis.LINC00626 can af-fect the proliferation,apoptosis,and drug sensitivity of SW480 cells and alter the expression of apoptotic pro-teins.

Objective:To observe the effect of intermittent theta burst transcranial magnetic stimulation (iTBS) on the language use, daily communication, and serum brain-derived neurotrophic factor (BDNF) levels of stroke survivors with motor aphasia (PSMA).Methods:A total of 60 PSMA patients were recruited and randomly divided into a control group and a treatment group, each of 30. Both groups received conventional speech training, while the treatment group additionally received daily 10-minute iTBS stimulation over the left dorsolateral prefrontal cortex, five days per week, for two weeks. Before and after the treatment, language function and daily communication were assessed using the Chinese Rehabilitation Research Center Standard Aphasia Examination (CRRCAE) and the Communication Activities of Daily Living (CADL) scale. Serum BDNF levels were measured using enzyme-linked immunosorbent assay.Results:After treatment, the CRRCAE and CADL scores in the treatment group were significantly higher than among the control group. The post-treatment serum BDNF levels in the treatment and control groups were (27.03±6.91)ng/ml and (22.20±5.89)ng/ml, respectively, both significantly higher than their pre-treatment levels. The average post-treatment serum BDNF level in the treatment group was significantly higher than the control group′s average.Conclusions:iTBS stimulation with speech training can better improve the language function and daily communication ability of stroke survivors with motor aphasia. The mechanism may be related to increased serum BDNF level.
