Endometriosis, a prevalent but debilitating condition affecting women, poses significant challenges in diagnosis and management. The current 2024 guideline, developed by the Korean Society of Endometriosis (KSE), builds upon the 2018 KSE guideline. This guideline aims to provide customized recommendations tailored to Korea’s unique clinical aspects and medical environment, and addresses key areas such as diagnosis, medical and surgical management, considerations for special populations, and its complex relationship with cancer.

Objectives: This study aimed to explore factors influencing satisfaction with medical services among medically underserved populations at the free medical clinic, providing data to improve free medical services for these populations. Methods: We employed a descriptive correlational study design involving 112 individuals (aged 19 years and older) from medically underserved populations who visited the clinic. Data were collected through face-to-face surveys from September to October 2023, and statistical analyses (t-tests, analysis of variance, Pearson correlation, and hierarchical multiple regression) were used to identify key predictors of satisfaction. Results: Perceived support from healthcare providers emerged as the strongest predictor ofsatisfaction with medical services, demonstrating a significant positive association. While socialsupport was positively correlated with perceived support from healthcare providers, it did not independently predict satisfaction. Conclusion These findings underscore the importance of healthcare provider and social supportin increasing satisfaction with medical services among medically underserved populations.Developing tailored healthcare programs and specialized healthcare provider training are essential strategies to improve healthcare access and outcomes for these vulnerable groups.

Objective: Deficits in social cognition (mentalization) and other cognitive deficits have been reported in patients with major depressive disorder (MDD) and may influence treatment response. This study examined the impact of cognitive function on treatment response of patients with MDD after 8 weeks of medication and whether the impact was mediated by mentalization. Methods: Cognitive function (memory, attention, executive function, processing speed) and mentalization were measured in 28 patients with MDD at baseline using neuropsychological tests and self-report scales. The treatment response was defined as the rate of improvement in symptom severity and global function. Results: Multiple regression analyses, controlling for mentalization and cognitive function, separately revealed that delayed recall was a negative predictor of functional improvement after 8 weeks of treatment, while mentalization was a positive predictor. A single mediation model using PROCESS macro showed that delayed recall and Digit Span backward indirectly affected functional improvement, mediated by mentalization. When age at onset was controlled for as a covariate, the mediating effect lost significance, and the direct effect of delayed recall on functional improvement was still significant. Conclusion Despite the small sample size, our results provide evidence that patients with MDD and low memory (delayed recall) at baseline may benefit more from short-term pharmacological treatments.

For patients with a few remaining abutment teeth, traditional removable partial dentures and implant-supported fixed prostheses are common treatment options.However, removable dentures often struggle to provide stability, especially as bone resorption occurs over time. Implant-supported fixed prostheses offer longterm stability but are costly and affected by anatomical and medical factors. A newer option is implant-assisted removable partial dentures, which use a minimal number of implants combined with a surveyed crown. This approach enhances support, retention, and stability while reducing financial and surgical burdens. It also improves the prognosis of the remaining teeth, increases patient satisfaction, and enhances masticatory function, making it a promising alternative to conventional removable dentures.

The role of acetylated apurinic/apyrimidinic endonuclease 1/redox factor 1 (APE1/Ref-1) in ovarian cancer remains poorly understood. Therefore, this study aimed to investigate the combined effect of recombinant human APE1/Ref-1 (rhAPE1/Ref-1) and aspirin (ASA) on two ovarian cancer cells, PEO-14, and CAOV3.The viability and apoptosis of ovarian cancer cells treated with rhAPE1/Ref-1 or ASA were assessed. Our results demonstrated that ASA induced rhAPE1/Ref-1 acetylation and widespread hyperacetylation in PEO-14 cells. Additionally, co-treatment with rhAPE1/Ref-1 and ASA substantially reduced cell viability and induced PEO-14 cell apoptosis, not CAOV3, in a dose-dependent manner. ASA increased the expression and membrane localization of the receptor for advanced glycation endproducts (RAGEs). Acetylated APE1/Ref-1 showed enhanced binding to RAGEs. In contrast, RAGE knockdown reduced cell death and poly(ADP-ribose) polymerase cleavage caused by rhAPE1/Ref-1 and ASA combination treatment, highlighting the importance of the APE1/Ref-1-RAGE interaction in triggering apoptosis. Moreover, combination treatment with rhAPE1/Ref-1 and ASA effectively induced apoptosis in 3D spheroid cultures of PEO-14 cells, a model that better mimics the tumor microenvironment. These results demonstrate that acetylated APE1/Ref-1 and its interaction with RAGE is a potential therapeutic target for ovarian cancer. Thus, the combination of ASA and APE1/Ref-1 may offer a promising new strategy for inducing cancer cell death.

Purpose: This retrospective cohort study aimed to investigate the association between the use of pain medications with varying cyclooxygenase-2 (COX-2) selectivity and the incidence of endometriosis (EMS) in women. Materials and Methods: Medical records from January 1, 1994, to December 31, 2022, were retrospectively analyzed. The cohort included 33406 patients diagnosed with any pain-related condition who were prescribed either selective COX-2 inhibitors or nonsteroidal anti-inflammatory drugs (NSAIDs). Patients were followed for up to 5 years from the cohort entry date. The incidence of EMS was compared between the two medication groups using Cox proportional hazards models, adjusting for confounding factors such as age, past drug use, and prior diagnosis. Results: The incidence rates of EMS were 3.00 per 1000 person-years in the COX-2 inhibitor group and 3.97 per 1000 person-years in the NSAIDs group. After adjustment for confounders, the hazard ratio for EMS incidence in the COX-2 inhibitor group compared to the NSAIDs group was 0.77 [95% confidence interval (CI), 0.63 to 0.93; p<0.01], indicating a significantly lower risk in the COX-2 inhibitor group. Subgroup analysis revealed that this association was particularly significant in younger women aged 20– 44 years, with a hazard ratio of 0.71 (95% CI, 0.54 to 0.95; p<0.05) in this age group. Conclusion The findings suggest that COX-2 inhibitors may reduce the incidence of EMS compared to traditional NSAIDs, highlighting their potential as a strategic option for managing EMS, particularly among younger women. Further prospective studies are needed to confirm these findings.

Systemic corticosteroids play an essential role in the management of asthma. During acute exacerbation, the short-term use of systemic corticosteroids is recommended. For patients with uncontrolled asthma and severe asthma, long-term and low-dose oral corticosteroids (OCS) have frequently been advocated. However, both short-term and long-term use of systemic corticosteroids carry the risk of adverse events (AEs), including various morbidities and even mortality. Despite recent progress in adult severe asthma management and the availability of new treatment options, the current domestic guidelines for asthma do not provide specific recommendations for oral corticosteroid tapering in patients with severe asthma. Therefore, the task force team of the severe asthma working group in the Korean Academy of Allergy, Asthma, and Clinical Immunology has proposed a tapering protocol for systemic corticosteroid use in severe asthma. This includes practical recommendations for monitoring OCS-related AE, particularly for adrenal insufficiency and osteoporosis, which suggests corticosteroid-sparing strategies that include alternative therapies, modifying treatable traits, timely specialist assessment, and shared decision-making with patients. However, further real-world research and collaboration with doctors from primary and academic institutes, patients, and policymakers are necessary to establish an OCS stewardship approach. This should include realistic OCS-tapering strategies for patients with severe asthma using regular OCS, education, and campaigns for patients, the public, and healthcare providers about the burden of severe asthma, as well as improving timely access to specialized severe asthma services for optimal management.

Purpose: This network meta-analysis aimed to evaluate the relative efficacy of systemic treatments in patients with relapsed/refractory chronic lymphocytic leukemia (R/R CLL), focusing on key genetic mutations, specifically the 17p deletion and TP53 mutations. Methods: We conducted a systematic literature review to identify all publicly available randomized controlled trials (RCTs) using PubMed, EMBASE, the Cochrane database, and meeting abstracts published through December 2023.A Bayesian network meta-analysis was performed to estimate the hazard ratios (HRs) for progression-free survival (PFS) with 95% confidence intervals (CIs) and to determine the ranking of the included regimens. Results: Twelve trials involving 4,437 patients and 13 treatment options were included in the meta-analysis. Venetoclax plus rituximab and zanubrutinib emerged as the most effective treatments for the overall R/R CLL population, showing the lowest PFS HR (HR 0.62, 95% CI 0.32–1.20 and HR 0.65, 95% CI 0.49–0.86, respectively) versus ibrutinib, and were ranked as the best agent (surface under the cumulative ranking curve [SUCRA] value of both 90%, respectively) among the included drugs. In the 17p deletion/TP53 mutation subgroup, zanubrutinib demonstrated the most favorable efficacy (HR 0.52, 95% CI 0.31–0.88 versus ibrutinib) with the highest SUCRA value (97%). In patients without these mutations, venetoclax plus rituximab was the most effective (HR 0.49, 95% CI 0.26–0.94 versus ibrutinib) with a SUCRA value of 94%. Conclusion Our findings highlight the superior efficacy of venetoclax plus rituximab and zanubrutinib for treating R/R CLL and confirm that the role of each regimen may vary depending on the clinically significant mutations.

We report a case of complete remission in anaplastic oligodendroglioma following adoptive cell therapy (ACT) with autologous Wilms tumor 1 (WT-1)-specific CD8+ T cells. A 40-year-old woman referred to our hospital for adjuvant chemotherapy after recurrent anaplastic oligodendroglioma initially presented with a left frontal tumor, diagnosed through seizure onset, and subtotal resection confirmed oligodendroglioma (WHO grade 2). Radiation therapy treated the residual tumor, achieving partial remission until recurrence 2.5 years later when malignant transformation to anaplastic oligodendroglioma (WHO grade 3) occurred following a second craniotomy. After three cycles of procarbazine, lomustine, and vincristine chemotherapy, the residual tumor stabilized for 3 years. However, follow-up MRI identified a new enhancing lesion, prompting a third craniotomy. Recurrent anaplastic oligodendroglioma was confirmed, and adjuvant proton beam therapy and temozolomide chemotherapy were initiated. Two years later, another enhancing lesion appeared on the adjacent medial frontal lobe. Following multidisciplinary review, we introduced WT-1-specific ACT. Although transient swelling was observed 1 month post-therapy, the tumor demonstrated a response within 3–9 months. Continued regression led to complete remission—confirmed via MRI at the 15-month follow-up and sustained for 4.7 years. The patient’s peripheral blood monocyte profiles and immune-associated cytokine analysis indicated T-cell activation following WT-1 sensitization.
