Background: The objective of this study was to investigate sequential changes in range of motion (ROM) and histopathology of the joint capsule after remobilization in a rat adhesive capsulitis (AC) model using cast immobilization. Methods: Thirty-five 6-week-old Sprague-Dawley rats were immobilized with casting of the left shoulder. After 4 weeks, the rats were randomly divided into 7 groups (n = 5 per group) according to the duration of remobilization following cast removal: 0 (D0), 1 (W1), 2 (W2), 3 (W3), 4 (W4), 5 (W5), and 6 (W6) weeks. At each time point, 5 rats were euthanized for measurement of the glenohumeral abduction angle and evaluation of capsular thickness in the axillary recess. Results: Abduction angle was sequentially increased at each time point after remobilization with cast removal. Significant differences between immobilized and non-immobilized shoulders were observed at D0 (130.4° vs 161.3°), W1 (144.7° vs 160.7°), and W2 (142.3° vs 161.3°). Significant differences in capsular thickness of the axillary recess were observed between immobilized and non-immobilized shoulders at all time periods including D0 (98.0 μm vs. 12.9 μm), W1 (117.7 μm vs. 12.2 μm), W2 (115.7 μm vs.13.1 μm), W3 (54.1 μm vs. 14.9 μm), W4 (54.5 μm vs. 13.4 μm), W5 (23.8 μm vs. 13.5 μm), and W6 (19.8 μm vs. 12.4 μm). Significant differences in capsular fibrosis scores were observed between immobilized and non-immobilized shoulders at W1 (2.2 vs. 0.2) and W2 (2.2 vs. 0.0). Conclusions Our study showed that ROM increased sequentially after remobilization in a rat AC model using cast immobilization, and it was normalized at 6 weeks after cast removal. Capsular thickening decreased sequentially, but remained at 6 weeks after cast removal. These findings may provide useful information for further research into verifying potential therapeutic targets using a rat AC model with cast immobilization.

Background: Excess intake of added sugars contributes to obesity, type 2 diabetes mellitus (T2DM), cardiovascular disease (CVD), and premature mortality. Sugar-sweetened beverages (SSBs), the main source of added sugars, are consistently linked to adverse outcomes. Artificially sweetened beverages (ASBs) have been suggested as short-term substitutes, but evidence regarding benefits and harms remains inconclusive, and guidance is lacking. Methods: This consensus statement draws on a structured evidence review combining two approaches: an updated meta-analysis of randomized controlled trials (RCTs) assessing short- to intermediate-term effects of replacing SSBs with ASBs on weight and metabolic outcomes; and an umbrella review of systematic reviews of cohort studies evaluating long-term associations of SSBs and ASBs with major outcomes, including mortality, CVD, and T2DM. Results: In 14 RCTs (3–76 weeks), replacing SSBs with ASBs produced modest reductions in body weight (–0.73 kg) and body fat (–0.72%), with inconsistent effects on glycemic and cardiometabolic markers. Evidence from 20 systematic reviews of cohorts (up to 34 years follow-up) showed that higher intake of both SSBs and ASBs was associated with increased risks of T2DM, CVD, and mortality, with relative risks for ASBs similar to those for SSBs. Conclusion ASBs may serve as a short-term substitution for individuals with high SSB intake, particularly those at elevated metabolic risk. However, regular or long-term use is not recommended due to uncertain safety and potential reinforcement of sweet preference. Public health strategies should emphasize reducing both SSBs and ASBs, prioritizing water and unsweetened beverages as the ultimate goal.

Objective: : To investigate the clinical and radiological features of unruptured vertebral artery dissecting aneurysms (uVADAs) treated with reconstructive endovascular techniques and to evaluate the risk factors associated with unfavorable radiological outcomes while focusing on the flow diversion effect. Methods: : We retrospectively reviewed 86 patients with uVADAs treated at a single tertiary center between January 2009 and December 2022. The patients were categorized into the flow diversion group (patients with uVADAs treated with a flow diverter or multiple stents) and the non-flow diversion group (patients with one or fewer stent insertion). Unfavorable angiographic outcomes were defined as 1) recurrence after coil insertion regardless of stent deployment or 2) no regression after stent insertion without coil packing. Univariate and multivariate analyses were performed to assess the related risk factors. Results: : We observed 37 uVADAs in the flow diversion group. Recurrence or no regression occurred in two of 37 (9.1%) and 13 of 49 (27.7%) uVADAs in the flow and non-flow diversion groups, respectively. The treatment without flow diversion effect (non-flow diversion group; odds ratio [OR], 8.04; 95% confidence interval [CI], 1.23–52.57; p=0.003) and hypertension (OR, 22.09; 95% CI, 2.51–194.2; p=0.005) were significantly associated with unfavorable angiographic outcomes. Conclusion : The flow diversion effect using a flow diverter or multiple stents insertion, along with strict blood pressure control, may be an important factor in achieving favorable angiographic outcomes in uVADA treatment.

Background and Objectives: Clinical characteristics and outcomes in acute heart failure (AHF) vary by phenotype. We assessed phenotype-specific features, treatment patterns, and outcomes in a nationwide Korean cohort. Methods: The Korean Heart Failure III registry prospectively enrolled 7,351 AHF admissions at 47 hospitals. Among 6,777 patients with available left ventricular ejection fraction (EF), phenotypes were defined as heart failure with reduced EF (HFrEF, ≤40%), mildly reduced EF (HFmrEF,41–49%), or preserved EF (HFpEF, ≥50%). The primary endpoint was a 12-month composite of all-cause death or heart transplantation, evaluated from index admission and, among hospital survivors, from discharge. We used inverse probability weighting (multinomial generalized boosted models with stabilized, trimmed weights) and weighted Cox proportional-hazards models to estimate hazard ratios (HRs). Results: Phenotype distribution was 58.9% HFrEF, 13.6% HFmrEF, and 27.5% HFpEF. Crude 12-month composite rates from index admission were 13.4% (HFrEF), 12.7% (HFmrEF), and 16.8% (HFpEF). After weighting, from index admission, HFmrEF (HR, 0.892; 95% confidence interval [CI], 0.731–1.088) and HFpEF (HR, 1.101; 95% CI, 0.939–1.291) did not differ from HFrEF; from discharge, HFpEF had modestly higher risk (HR, 1.207; 95% CI, 1.008–1.445) whereas HFmrEF did not (HR, 1.039; 95% CI, 0.844–1.279). Hyponatremia and chronic kidney disease were consistent adverse markers, while angiotensin-converting enzyme inhibitor/ angiotensin II receptor blocker use at discharge was protective. Conclusions Across the EF spectrum, phenotypes showed distinct profiles and risk. Postdischarge risk was modestly higher in HFpEF, supporting phenotype-tailored care and systematic discharge optimization in Korean patients with AHF.

Purpose: Overactive bladder (OAB) symptoms may improve following surgical correction of cystocele. This study aimed to evaluate changes in urgency, the primary symptom of OAB, and identify factors associated with improvement in urgency after surgical treatment for cystocele. Methods: We conducted a retrospective analysis of medical records for patients who underwent surgical treatment for cystocele and had preoperative urgency measuring ≥3 on a 5-point urinary sensation scale. Patients were categorized into 2 groups based on their urgency status 3 months postsurgery: those with improved urgency and those without improvement. Improvement was defined as a reduction of 2 or more points on the scale following surgery. We compared preoperative clinical and urodynamic factors between the 2 groups. Results: A total of 137 patients were included in the study, with 98 (71.5%) showing improvement in urgency symptoms after surgery. The improved group had a significantly higher prevalence of preoperative urgency urinary incontinence (UUI) (62.2% vs. 30.8%, P=0.001) and bladder outlet obstruction (43.9% vs. 20.5%, P=0.011) compared to the nonimproved group. Urodynamic evaluations indicated that the detrusor pressure at maximum flow rate (PdetQmax) was significantly higher in the improved group than in the nonimproved group (P=0.004). Multivariate logistic regression analysis identified preoperative UUI, higher PdetQmax, and lower vaginal parity as independent predictors of improvement in urgency postoperatively. Conclusions Preoperative UUI, higher PdetQmax, and lower vaginal parity were significant predictors of postoperative improvement in urgency. Both clinical and urodynamic factors may help identify patients with cystocele and preoperative urgency who are most likely to benefit from anatomical correction.

Abrupt vessel closure (AVC) is a complication of percutaneous coronary intervention (PCI) and is defined as the sudden cessation of forward coronary blood flow due to a variety of mechanisms. The incidence of AVC has markedly decreased from approximately 3.0% in the early era to about 0.3% today. Nevertheless, cardiovascular interventionists must remain prepared to manage AVC effectively, given its significant impact on clinical outcomes.AVC can arise from several mechanisms, including dissection, intramural hematoma, intracoronary thrombosis, air embolism, vasospasm, and no-reflow. The clinical impact of AVC varies depending on the extent of myocardium affected, ranging from asymptomatic events or transient ischemic chest pain to cardiogenic shock or cardiac arrest. Both a general approach for stabilizing hemodynamic consequences and an etiology-specific management strategy are essential. Hasty decision-making may worsen the situation, whereas a structured approach—focused on hemodynamic stabilization, logical diagnostic processes, and targeted interventions—can improve outcomes. In this narrative review, we describe the mechanisms underlying each etiology, outline mechanism-specific management strategies, and discuss general approaches to managing patients with AVC through logical diagnostic and treatment processes. We hope this review offers valuable insights into this uncommon but significant complication and enhances readers’ skills in managing AVC more effectively during PCI.

Objective: To assess the incidence and risk of psychiatric disorders, including depression, anxiety, and trauma-related disorders, in individuals who underwent globe and orbital ablative surgeries compared to a matched control group. Methods: This retrospective cohort study used Korean National Health Insurance Service data. The cohort included 338,767 individuals, with 16,545 in the surgery group (orbital exenteration, enucleation, or evisceration, 2003–2021) and 322,222 matched controls. After exclusions, 12,965 patients were matched with 251,445 controls via propensity score matching. The cumulative incidence and risk of psychiatric disorders, including depression (F32.x, F34.0, F34.1), anxiety (F40.x, F41.x), and trauma-related disorders (F43.x), over three years post-surgery. Kaplan-Meier analysis assessed cumulative incidence, while Cox proportional hazards regression estimated adjusted hazard ratios (HRs) and 95% confidence intervals (CIs). Results: A total of 264,410 individuals (mean age, 54.4 years; 63.3% man) were included. The surgery group had significantly higher cumulative incidence of psychiatric disorders (log-rank p<0.001). The incidence rate ratio was 1.63 (95% CI, 1.52–1.75). Risk was greatest in younger individuals (incidence rate ratio, 2.15; 95% CI, 1.75–2.64) and men (1.77 vs. 1.48 in women). Higher comorbidities were associated with lower risk (HR: 0.91 in men, 0.90 in women), as was higher socioeconomic status (HR: 0.76 in men, 0.68 in women). Conclusion Globe and orbital ablative surgeries were associated with significantly increased psychiatric risk, particularly in younger men. Higher comorbidities and socioeconomic status appeared to mitigate this risk. Integrated mental health support should be considered in postoperative care.

Background: Rosacea is a chronic inflammatory skin disorder characterized by erythema, papules, ocular symptoms, and heightened sensitivity. Patients with neurogenic symptoms such as burning or stinging remain particularly difficult to manage. Current guidelines often underrepresent energy-based devices (EBDs), pigmentary sequelae, psychosocial burden, and ocular comorbidities. Objective: To examine Korean dermatologists’ expert perspectives on rosacea management, focusing on skin sensitivity, neurogenic symptoms, pigmentary changes, psychosocial impact, ocular involvement, and EBD use. Methods: A web-based, 29-item survey was administered to 25 board-certified Korean dermatologists (May–June 2025). Quantitative and qualitative responses were analyzed. Results: Erythematotelangiectatic and papulopustular phenotypes with sensitivity skin predominated. EBDs (pulsed dye laser, intense pulsed light) were frequently used but limited by cost and sensitivity issues. Neurogenic symptoms were recognized but rarely treated with neuromodulators. Post-inflammatory hyperpigmentation was infrequent, yet monitoring was inconsistent.Psychosocial and ocular aspects were acknowledged but seldomly systematically addressed.Respondents expressed interest in emerging adjunctive treatments such as cold plasma, skin boosters, and holistic care approaches. Conclusion Korean dermatologists adopt individualized strategies for rosacea, yet practice gaps remain regarding neurogenic symptoms, pigmentary complications, and psychosocial and ocular comorbidities. Findings support the need for updated multidisciplinary, phenotype-driven guidelines aligned with real-world practice.
