Heart failure (HF) is a major cause of mortality and morbidity in South Korea, imposing substantial physical, emotional, and financial burdens on patients and society. Despite the high burden of symptom and complex care needs of HF patients, palliative care and hospice services remain underutilized in South Korea due to cultural, institutional, and knowledge-related barriers. This position statement from the Korean Society of Heart Failure emphasizes the need for integrating palliative and hospice care into HF management to improve quality of life and support holistic care for patients and their families. By clarifying the role of palliative care in HF and proposing practical referral criteria, this position statement aims to bridge the gap between HF and palliative care services in South Korea, ultimately improving patient-centered outcomes and aligning treatment with the goals and values of HF patients.

Purpose: This study aimed to evaluate and optimize microbial DNA extraction methods from urine, a non-invasive sample source, to enhance DNA quality, purity, and reliability for urinary microbiome research and biomarker discovery in bladder cancer. Materials and Methods: A total of 302 individuals (258 with genitourinary cancers and 44 with benign urologic diseases) participated in this study. Urine samples were collected via sterile catheterization, resulting in 445 vials for microbial analysis. DNA extraction was performed using three protocols: the standard protocol (SP), water dilution protocol (WDP), and chelation-assisted protocol (CAP). DNA quality (concentration, purity, and contamination levels) was assessed using NanoDrop spectrophotometry.Microbial analysis was conducted on 138 samples (108 cancerous and 30 benign) using 16S rRNA sequencing. Prior to sequencing on the Illumina MiSeq platform, Victor 3 fluorometry was used for validation. Results: WDP outperformed other methods, achieving significantly higher 260/280 and 260/230 ratios, indicating superior DNA purity and reduced contamination, while maintaining reliable DNA yields. CAP was excluded due to poor performance across all metrics. Microbial abundance was significantly higher in WDP-extracted samples (p<0.0001), whereas SP demonstrated higher alpha diversity indices (p<0.01), likely due to improved detection of low-abundance taxa. Beta diversity analysis showed no significant compositional differences between SP and WDP (p=1.0), supporting the reliability of WDP for microbiome research. Conclusions WDP is a highly effective and reliable method for microbial DNA extraction from urine, ensuring high-quality and reproducible results. Future research should address sample variability and crystal precipitation to further refine microbiome-based diagnostics and therapeutics.

Vertebral arteriovenous fistula (VAVF) is a rare lesion characterized by an abnormal connection between the extracranial vertebral artery and the surrounding venous plexus. It typically arises due to penetrating injury, although it can occasionally result from blunt trauma. Brachial plexus injury (BPI) is also infrequently associated with VAVF. We present a rare case of VAVF caused by blunt trauma, which resulted in BPI. The patient, who had previously sustained a C2 fracture and C2–3 myelopathy from a bicycle accident, presented with new-onset weakness in the right upper extremity. His previous clinical history led to an initial suspicion of either an exacerbation of a pre-existing lesion or a shoulder injury. However, electromyography indicated that the weakness was due to BPI. Further evaluations later revealed VAVF to be the primary cause of the BPI. VAVF must be recognized as a rare potential reason for BPI, as timely intervention is essential for improving patient recovery and prognosis.

The initial molecular cytogenetic characteristics of blasts plays a significant role in determining the treatment course of B-cell acute lymphoblastic leukemia (B-ALL).B-ALL with intrachromosomal amplification of chromosome 21 (iAMP21) has been well known to have unfavorable prognosis. Also, there are previously recognized germline mutations that increase the risk of ALL, such as trisomy 21, Down syndrome. This case report is about a 16-year-old girl who presented with lymphadenitis, purpura, and fever followed by initial lab of elevated white blood cell with blasts.She had some notable facial features, but no typical Down syndrome related one.Bone marrow biopsy and fluorescence in situ hybridization finalized the diagnosis as B-ALL with iAMP21, high-risk group. The minimal residual disease-negative complete remission was achieved after the induction chemotherapy with Korean multicenter high-risk protocol. However, abnormal karyotype was sustained in bone marrow. Microarrays with her buccal swab raised the possibility that the abnormal karyotype was not from the leukemic blasts but rather from the germline. Although she underwent scheduled chemotherapy uneventfully as slow early responder type, thrombocytopenia and abnormal karyotype persisted, leading to the diagnosis of acute myeloid leukemia. Additional chemotherapy and peripheral blood stem cell transplantation was performed which resulted in engraftment. This case highlights the discovery of a constitutional genetic aberration, which played like a silent yet critical background factor for B-ALL with iAMP21. As the number of reported cases are limited, the role of germline chromosome 21 mutation as the indicator for prognosis of B-ALL should be studied further.

Objective: We aimed to investigate the effectiveness of buspirone as an adjunctive therapy for alleviating anxiety symptoms in patients with depressive disorders who are already taking antidepressants. Methods: This was an open-label prospective multicenter non-interventional observational study conducted over 12 weeks. We enrolled 180 patients diagnosed with depressive disorders according to DSM-5 criteria and Hamilton Anxiety Rating Scale (HAMA) scores ≥ 18. Participants were already taking selective serotonin reuptake inhibitors or serotoninnorepinephrine reuptake inhibitors and were prescribed adjunctive buspirone. Efficacy was assessed using HAMA, Hamilton Depression Rating Scale (HAMD), Clinical Global Impression Scale-Improvement, Clinical Global Impression Scale-Severity, Sheehan Disability Scale (SDS), and WHO-5 Well-Being Index. Results: The efficacy analysis included 161 patients. HAMA scores decreased significantly from 25.2 ± 6.7 at baseline to 15.4 ± 8.6 at 12 weeks (p ＜ 0.001), whereas HAMD scores decreased from 19.4 ± 4.6 to 12.7 ± 5.7 (p ＜ 0.001).WHO-5 and SDS scores showed significant improvements. The HAMA response rate was 39.1% and the remission rate was 13.7% at 12 weeks. Adverse drug reactions were reported in 3.7% of participants. Subgroup analyses showed no significant differences in treatment response based on buspirone dosage, baseline anxiety/depression severity, or benzodiazepine use. Conclusion Adjunctive buspirone therapy effectively improved anxiety symptoms in depressed patients taking antidepressants, regardless of baseline symptom severity or buspirone dosage. The treatment was well-tolerated with few adverse events. Future studies using a control group are needed.

Objective: Recently, various mental health promotion programs using virtual reality (VR) technology have been tried in the psychiatric field. Considering the importance of mental health in pregnant women, VR-assisted mental health promotion programs for pregnant women are needed to be developed. This study aimed to prospectively investigate the efficacy of a VR-assisted mental health promotion program for pregnant women. Methods: Fifty-five pregnant women were participated in this study. Mental health states such as depression, anxiety, perceived stress, and quality of life were assessed by Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), Perceived Stress Scale, and World Health Organization Quality of Life Scale Abbreviated Version (WHOQOL-BREF) before and after using VR program treatment. Based on the mental health types of pregnant women classified by cluster analysis, the effects of the VR program were analyzed by paired t test and Wilcoxon signed rank test. Results: The VR program significantly reduced PHQ-9 (p = 0.033) and GAD-7 (p = 0.046) scores, and significantly increased WHOQOL-BREF (p = 0.026) score of the participants. Additionally, when classifying the mental health types of pregnant women, the VR program was significantly effective to improve depression, anxiety, and quality of life in the most severe group based on the cluster analysis. Conclusion The results of this study suggest that VR program may be effective to improve the mental health of pregnant women. Particularly, VR programs for the high-risk group of depression might be the most effective. Therefore, VR-assisted mental health promotion programs could be useful for managing the mental health in pregnant women.

Background: This study aimed to assess the severity of postoperative delirium (PD) in elderly patients who underwent reverse total shoulder arthroplasty (rTSA) for irreparable massive rotator cuff tears (mRCTs) under general anesthesia (GA) compared to those under interscalene block (IB). Methods: Forty elderly patients aged 65 years or older diagnosed with an irreparable mRCT who underwent rTSA were included in the prospective case-controlled study. Of these, 20 patients were operated under GA and the other 20 under IB. The average age was 77.1 years (range, 65–95 years). The severity of delirious symptoms was evaluated by the Delirium Rating Scale–revised–98 (DRS) score from the patients or guardians before the surgery and at 0, 3, and 7 days and 1, 3, and 6 months after the surgery and compared between the 2 groups. Results: Immediately after surgery, the visual analog scale score difference between the groups was statistically significant, with the GA group at 6.25 (standard deviation, ± 0.85) and the IB group at 3.80 (± 0.62) (p < 0.001). On the day of operation, the mean DRS score in the GA and IB groups were 9.10 (± 5.63) and 6.60 (± 5.33), respectively (p = 0.157). On day 3 of surgery, the mean DRS score in the GA group peaked to 9.95 (± 8.73), while in the IB group, it declined to 6.40 (±5.81) (p = 0.138). After 3 days, DRS scores showed a decreasing trend in both groups. When comparing the mean change (∆) from the preoperative baseline scores to the postoperative values, the ∆DRS score was significantly higher with 4.15 (± 4.53) points in the GA group as compared to 1.30 (± 1.92) in the IB group (p = 0.014). Conclusions IB can be an attractive and efficient anesthetic choice in preventing PD for elderly patients undergoing rTSA for irreparable mRCTs. The IB group showed lower DRS scores and a peak on day 0 compared to the higher DRS scores and peak on day 3 in the GA group. Additionally, IB showed less pain than GA.

The detrimental effects of hyperlipidemia on the healing of rotator cuff tears are well documented. The proposed underlying mechanisms for these effects include alterations in the extracellular matrix, inflammation, and oxidative stress, which hamper the reparative processes in the affected tendon tissues. Recent therapeutic strategies target these pathways, reflecting a growing body of research dedicated to mitigating these effects and promoting healing. This literature review aims to provide a comprehensive understanding of the pathophysiology underlying rotator cuff tears, examine the interplay between hyperlipidemia and rotator cuff tear healing, synthesize current knowledge on contributing biological mechanisms, and outline potential therapeutic interventions to optimize clinical management and treatment outcomes for patients.

Background: Not reducing the posterior malleolar fragment could have an impact on the alignment and stability of syndesmosis since the posterior inferior tibiofibular ligament (PITFL) originates at the posterior malleolar fragment. Given that these alignment and stability changes may contribute to discomfort and pain, further research may be required. We think that our new classification method will be able to help improve understanding of treatment methods for posterior malleolar fractures. Methods: We retrospectively analyzed 206 patients who underwent surgeries for ankle fractures in our orthopedic clinic between April 2014 and December 2022 and were verified to have posterior malleolar fractures in plain radiography, computed tomography (CT), and magnetic resonance imaging (MRI). We performed a probing test to determine whether syndesmosis was stable. Results: We were able to classify the 206 cases into the following 5 types: type 1 (31 cases, 15.0%), extraincisural fragment with an intact fibular notch; type 2 (98 cases, 47.5%), posterolateral fragment extending into the fibular notch; type 3 (37 cases, 17.9%), posteromedial 2-part fragment involving the medial malleolus; type 4 (19 cases, 9.2%), large posterolateral triangular fragment;and type 5 (21 cases, 10.1%), shell-like PITFL avulsion (< 2 mm) in a CT axial view or PITFL periosteal sleeve avulsion (PITPSA) in arthroscopic or MRI findings. Conclusions This new system that adds the PITPSA type for the classification of posterior malleolar fractures may be a useful approach to managing these injuries and may aid in treatment decision-making. It could be important to consider ligament surgery when treating PITPSA.

Background: This study aimed to compare the effectiveness and complications between classic palmaris longus tendon landmark-based corticosteroid injection (CI) and transverse carpal ligament (TCL)-penetrating CI for carpal tunnel syndrome (CTS). Methods: We performed a landmark-based CI on one hand and a TCL-penetrating CI on the other side after randomization in 30 consecutive patients with bilateral CTS. The pain visual analog scale (VAS) and the Boston Carpal Tunnel Questionnaire (BCTQ) were assessed at baseline, 4 weeks, and 3 and 6 months after injection. Skin hypopigmentation of the injection site was evaluated using the modified Vancouver scar scale (mVSS). Pain during needle insertion was evaluated using a VAS for each hand. Results: The mean patient age was 56 ± 11 years (range, 32–77 years), and 27 patients (90.0%) were women. The pain VAS, BCTQ scores, and the incidence of skin hypopigmentation were not significantly different between the 2 groups after injection, but the mean mVSS scores were significantly higher in the landmark-based CI group at all time points. The pain VAS score during needle insertion was significantly higher in the TCL-penetrating CI group. Conclusions When comparing the pain VAS and BCTQ scores, the difference between the 2 groups was not statistically significant. TCL-penetrating CI causes considerable pain during needle insertion but causes less severe skin hypopigmentation than landmark-based CI in CTS treatment.
