Title: Incidence of glaucoma in patients with systemic lupus erythematosus: a nationwide cohort study in South Korea Authors: Kim, Ji Hong; Kim, Yunjin; Oraha, Kathy Michelle; Park, Hae Min; Kim, Yu Jeong; Lim, Han Woong; Sung, Yoon-Kyoung; Welsbie, Derek S.; Lee, Won June Abstract: Background/aims To assess the incidence of glaucoma in patients with systemic lupus erythematosus (SLE) and to identify associated risk factors using a nationwide population-based cohort. Methods This retrospective cohort study analysed data from the Korean National Health Insurance Service (2008-2022). A total of 9682 patients with SLE were identified using ICD-10 code M32 and rare intractable disease code V136 and matched 1:1 to non-SLE controls by age and sex. The incidence of glaucoma (ICD-10 codes H40 and H42) and glaucoma suspect (H40.0) was assessed. Multivariate logistic regression was used to identify risk factors for glaucoma, including long-term corticosteroid use (>= 180 days). Results The incidence of glaucoma was significantly higher in the SLE group than in controls (11.34% vs 3.74%; p<0.0001), with a greater prevalence in younger patients (<40 years) and females. Glaucoma suspect cases were also more common in the SLE group (35.56% vs 30.25%; p<0.0001). SLE was independently associated with glaucoma (adjusted OR: 2.00, 95% CI 1.69 to 2.38), and prolonged corticosteroid use further increased the risk (OR: 1.75, 95% CI 1.51 to 2.02). Annual incidence trends showed a rising pattern over time, especially among SLE patients. Conclusions SLE is associated with an increased risk of glaucoma, particularly among younger individuals and females. Prolonged corticosteroid therapy significantly contributes to this risk. These findings support the need for regular ophthalmic screening and judicious corticosteroid management in patients with SLE.

Title: Mechanical versus bioprosthetic heart valves in patients on hemodialysis Authors: Ro, Sun Kyun; Kim, Jiyeong; Ryu, Soorack; Kim, Joon Bum Abstract: Objectives: Appropriate valve selection in patients on hemodialysis requiring valve replacement is a highly contentious issue because of these patients’ short life expectancy and accelerated deterioration of bioprosthetic valves. This study aims to analyze clinical outcomes on the basis of the types of prosthetic valves and to estimate life expectancy and valve durability in this cohort. Methods: In total, 765 patients on hemodialysis undergoing first-time valve replacement were extracted from the Korean National Health Insurance Sharing Service database. Clinical outcomes were compared between the bioprosthetic (n = 421) and mechanical (MP; n = 344) valve groups. An age-dependent subgroup analysis was conducted, and the median survival time was calculated. A competing risk analysis for late clinical events was also performed. Results: After adjustment, the early clinical outcomes and late mortality were comparable between the 2 groups. Redo aortic valve replacements (AVRs) occurred more frequently in the bioprosthetic group (1.3%/patient-year vs 0.3%/patient-year; P = .002), whereas gastrointestinal bleeding was more common in the MP group (7.0%/patient-year vs 4.8%/patient-year; P = .010). The 2 groups did not show significant survival differences in all age-dependent subgroups. The estimated median survival times were 6.6, 4.0, and 2.1 years for patients aged <50, 50-64, and ≥65 years, respectively. Competing risk analysis showed a lower prevalence of redo AVRs and a greater prevalence of major bleeding events with MP use (adjusted subdistribution hazard ratio, 0.24 [0.09-0.66]; P = .006 and 1.46 [1.13-1.89]; P = .004). Conclusions: Given the considerably short lifespan of patients on hemodialysis, bioprosthetic valves may be a reasonable option for younger patients, except for those with hypercalcemia or potential candidates for kidney transplantation.

Title: Randomized Clinical Trial of Imagery Stabilization and Rescripting Therapy for Psychiatric Outpatients with Posttraumatic Stress Disorder Authors: Kim, Daeho; Ryu, Soorack; Min, Ji Young; Lee, Hyunji; Kim, Eunkyung Abstract: Purpose: To examine the safety and effectiveness of a novel psychotherapy based on imagery techniques, we conducted a randomized clinical trial comparing imagery stabilization and rescripting therapy (ISRT) with non-trauma-focused cognitive behavioral therapy (CBT) for adults with posttraumatic stress disorder (PTSD). Materials and Methods: Eight sessions of 60-minute ISRT were conducted for the treatment condition (n=59), while the control group received eight sessions of 60 minutes of CBT (n=27). The Clinician-Administered PTSD Scale for Diagnostic and Statistical tered by clinicians, while self-questionnaires were administered at pretreatment, posttreatment, and the 6-month follow-up. Results: Forty-two participants in the ISRT group and 20 participants in the CBT group completed more than six sessions; thus, dropout rates were not significantly different between the groups (17/59, 28.8% vs. 7/27, 25.9%, respectively). Although no statistical differences were found between conditions, both completer and intention-to-treatment analyses revealed that clinical status, PTSD symptoms, and quality of life favored ISRT after treatment and 6 months later. Conclusion: Our findings suggest that ISRT is a safe and effective treatment option for PTSD.

Title: Staple line coverage with suture fixation of polyglycolic acid patch for primary spontaneous pneumothorax Authors: Kim, Yeon Soo; Ryu, Soorack Abstract: Background: Video-assisted thoracoscopic surgery is the standard surgical treatment for primary spontaneous pneumothorax (PSP). Various attempts, including absorbable mesh and fibrin glue, have been made to reduce surgical complications such as postoperative prolonged air leaks and recurrence. This retrospective study evaluates whether suturing a polyglycolic acid (PGA) patch to a surgical staple line can reduce postoperative air leakage. Methods: This study included 135 patients under the age of 40 years who underwent thoracoscopic PSP surgery between September 2013 and February 2023. A PGA patch and fibrin glue were used, and in each case, a single surgeon performed the surgery and coordinated postoperative care. Patients who underwent other surgery on the same side or required five or more staples were excluded. Methods for reinforcing the staple line included multiple sutures on the PGA patch and staple line (n=28, group A), a single suture (n=34, group B), and fibrin glue alone (n=73, group C). In group A, suturing was performed at both ends of the staple line and wherever it was considered necessary. In group B, suturing was performed at the center of the staple line. Results: The demographic data showed no significant differences among the three groups. Furthermore, the groups did not differ significantly in operation indication, operation time, complications, incision number, or cartridge number, but the bleb characteristics did differ. After adjusting for bleb characteristics, groups A and B showed a statistically significant decrease in air leakage, compared with group C (P<0.01), and the postoperative air leakage duration was significantly shorter in group A than group B (P=0.047). Conclusions: When the PGA patch was sutured to the staple line, postoperative air leakage was significantly reduced, compared with cases in which the PGA patch was secured with fibrin sealant alone. When multiple sutures were applied to the staple line and PGA patch, postoperative air leakage tended to decrease compared with the group that received a single suture. Covering the staple line under a PGA patch with suture fixation can reduce air leakage after wedge resection for pneumothorax.
