Introduction: The primary issue following lumbar discectomy for disc herniation is the risk of reherniation in the post-operative period. Many surgical techniques have been proposed to treat disc reherniation, however, the optimal one remains variable. This meta-analysis aimed to investigate the prevalence of symptomatic reherniation after using a Bone-anchored annular closure device following lumbar discectomy and the contributing factors. Materials and methods: Identification of published literature was performed on PubMed, Google Scholar, Scopus, and Web of Science databases. Studies published until 14 February 2024 reported the prevalence of symptomatic reherniation after using a Bone-anchored annular closure device following lumbar discectomy and the associated contributing factors. A random effects model was used to conduct Bayesian frequentist network meta-analysis and pair-wise meta-analysis, with the assessment based on standardised mean difference (SMD) and 95% confidence interval (CI). Results: Eleven studies published in 2012 − 2022 recruiting a total of 5195 patients were included in the meta-analysis. The prevalence of reherniation in ACD and control groups was 23.2% (95% CI: 18.2% − 28.1%) and 36.4% (95% CI: 28.2% − 44.5%), respectively. The moderator effect of sample size is significant for pooled data of the ACD group (p-mod=0.002), but not for the control group (pmod=0.278). After the adjustment with sample size, the prevalence rates were 13.6% (95% CI: 6.2% − 21.1%) and 29.6% (95% CI: 14.9% − 33.2%) for ACD and control groups, respectively. Conclusion: Comparatively to lumbar discectomy alone, using a Bone-anchored annular closure device following lumbar discectomy decreased the symptomatic reherniation rate and post-operative complications, as well as the necessity for subsequent surgeries.

Background: In this study, we aimed to investigate postoperative radiographic parameters for predicting flexor tendon rupture after volar plate fixation for distal radius fractures. Methods: In this retrospective cohort study, postoperative radiographs of 15 cases of flexor tendon rupture were included as a flexor tendon rupture group. Additionally, data from 45 patients with non-flexor tendon rupture (control group), matched in terms of age, sex, and fracture type (1 : 3) to the flexor tendon rupture group, were reviewed in terms of fracture reduction and plate position. We assessed the Soong grade, plate-to-critical line distance (PCLD), and plate-to-volar rim distance to determine plate position and used other parameters to analyze anatomical reduction including radial tilt, ulnar variance, coronal carpal translation, radius-radial styloid distance, volar tilt, sagittal carpal alignment (SCA), and radius-volar lip distance (RVLD). Results: We identified 3 significant predictive factors for flexor tendon rupture after volar plate fixation for distal radius fractures.The mean PCLD and SCA were significantly greater in the flexor tendon rupture group than in the control group (p < 0.001). The mean RVLD was smaller in the flexor tendon rupture group than in the control group (p = 0.033). Logistic regression analysis was performed to examine the importance of the variables. Conclusions Our findings underscore the importance of PCLD, SCA, and RVLD as significant risk factors for flexor tendon rupture.Accurate plate positioning, achieving appropriate anatomical reduction, and vigilant monitoring for signs of plate irritation in highrisk patients may help prevent flexor tendon rupture.

This paper discusses a rare case of a 49-year-old female diagnosed with a central nervous systemisolated neoplasm with histiocytic features, classified as histiocytic neoplasm, not otherwise specified (NOS). Despite comprehensive histopathological and genetic studies, accurately diagnosing the case proved challenging. Initial surgical findings and frozen biopsy suggested a low-grade glioma; however, subsequent immunohistochemistry and genetic analysis excluded known histiocytic subtypes such as ALK-positive histiocytosis and Erdheim-Chester disease. The patient’s condition improved following occupational rehabilitation therapy for right upper motor weakness, as well as anticonvulsant and radiation therapy, and her neurological condition remains stable. This case underscores the diagnostic challenges of Histiocytic Neoplasms and the necessity for interdisciplinary collaboration and sophisticated diagnostic techniques.

Background: The relationship between circulating lipid levels and the risk for heart failure (HF) is controversial. We aimed to examine this association, and whether it is modified by the duration of diabetes or treatment regimens in people with type 2 diabetes mellitus. Methods: Individuals (n=2,439,978) who underwent health examinations in 2015 to 2016 were identified from the Korean National Health Information Database. Subjects were categorized according to the duration of diabetes (new-onset, <5, 5–10, or ≥10 years) and number of antidiabetic medications. Incident HF was defined according to the International Classification of Diseases, 10th Revision (ICD-10) code I50 as the primary diagnosis during hospitalization. The risk for HF was estimated using multivariate Cox proportional hazard analysis. Results: During a median follow-up of 4.0 years, 151,624 cases of HF occurred. An inverse association between low-density lipoprotein cholesterol (LDL-C) levels and incident HF was observed in the new-onset diabetes group, with an approximately 25% lower risk in those with LDL-C levels of 100–129, 130–159, and ≥160 mg/dL, compared to those with levels <70 mg/dL. However, J-shaped associations were noted in the long-standing diabetes group, with a 16% higher risk in those with LDL-C level ≥160 mg/dL, compared to those with levels <70 mg/dL. Similar patterns were observed in the relationship between total cholesterol or non-high-density lipoprotein cholesterol and the risk for HF, and when subjects were grouped according to the number of antidiabetic medications instead of diabetes duration. Conclusion Different associations between lipid levels and the risk for HF were noted according to disease progression status among individuals with diabetes.

Background: Diabetes in older adults is becoming a significant public burden to South Korea. However, a comprehensive understanding of epidemiologic trends and the detailed clinical characteristics of older adults with diabetes is lacking. Therefore, we evaluated epidemiologic trends and the metabolic and lifestyle characteristics of diabetes in Korean older adults. Methods: We analyzed data from the Korea National Health and Nutrition Examination Survey to assess diabetes prevalence according to diabetes duration and lifestyle behaviors. In addition, we drew upon the National Health Information Database of the National Health Insurance System to assess physical activity levels, antidiabetic medication use, polypharmacy, medication adherence, and major comorbidities. Results: The absolute number of newly diagnosed cases of diabetes among older adults doubled over the past decade. Management rates of metabolic indicators were higher in older adults with diabetes compared to those without diabetes. The proportion of older adults with diabetes meeting the minimum recommended physical activity increased over the years. Compared to 10 years before, the use of dipeptidyl peptidase-4 inhibitor or sodium-glucose cotransporter-2 inhibitor had increased, as had comorbidities such as dyslipidemia, dementia, cancer, heart failure, atrial fibrillation, and chronic kidney disease. Initial medication adherence was significantly lower in those with end-stage kidney disease or dementia, insulin use, high-risk alcohol use, and living alone. Continuing insulin use 1 year after diagnosis of diabetes was significantly higher in those who initiated insulin therapy at diagnosis, had retinopathy, were on triple antidiabetic medications, and had a history of cancer. Conclusion Comprehensive management of metabolic indicators and physical activity is essential for older adults with diabetes. Improvements in prescribing guidelines, personalized management of age-related comorbidities, and individualized approaches that consider the heterogeneous nature of older adults with diabetes are desirable. Further research, such as high-quality cohort and intervention studies specific to older adults, is needed to establish evidence-based management for older adults with diabetes.

Extracellular vesicles (EVs) are lipid bilayer-enclosed particles carrying bioactive cargo, including nucleic acids, proteins, and lipids, facilitating intercellular and interorgan communication. In addition to traditional mediators such as hormones, metabolites, and cytokines, increasing evidence suggests that EVs are key modulators in various physiological and pathological processes, particularly influencing metabolic homeostasis and contributing to the progression of cardiometabolic diseases. This review provides an overview of the most recent insights into EV-mediated mechanisms involved in the pathogenesis of obesity, insulin resistance, diabetes mellitus, steatotic liver disease, atherosclerosis, and cardiovascular disease. EVs play a critical role in modulating insulin sensitivity, glucose homeostasis, systemic inflammation, and vascular health by transferring functional molecules to target cells. Understanding the EV-mediated network offers potential for identifying novel biomarkers and therapeutic targets, providing opportunities for EV-based interventions in cardiometabolic disease management. Although many challenges remain, this evolving field highlights the need for further research into EV biology and its translational applications in cardiovascular and metabolic health.
