Background:
Renal replacement therapy (RRT) is an important treatment option for sepsisassociated acute kidney injury (AKI); however, the optimal timing for its initiation remains controversial. Herein, we investigated the clinical outcomes of early continuous kidney replacement therapy (CKRT), defined as CKRT initiation within 6 hours of sepsis-associated AKI onset, which was earlier than the initiation time defined in previous studies.
Methods:
We used clinical data sourced from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. This study included patients aged ≥ 18 years who met the sepsis diagnostic criteria and received CKRT because of stage 2 or 3 AKI. Early and late CKRTs were defined as CKRT initiation within 6 hours and after 6 hours of the development of sepsisassociated AKI, respectively.
Results:
Of the 33,236 patients diagnosed with sepsis, 553 underwent CKRT for sepsisassociated AKI. After excluding cases of early mortality and patients with a dialysis history, 45 and 334 patients were included in the early and late CKRT groups, respectively. After propensity score matching, the 28-day mortality rate was significantly lower in the early CKRT group than in the late CKRT group (26.7% vs. 43.9%, P = 0.035). The early CKRT group also had a significantly greater number of days free of mechanical ventilation (median, 19; interquartile range [IQR], 3–25) and vasopressor administration (median, 21; IQR, 5–26) than the late CKRT group did (median, 10.5; IQR, 0–23; P = 0.037 and median, 13.5;IQR, 0–25; P = 0.028, respectively). The Kaplan–Meier curve also showed that early CKRT initiation was associated with an improved 28-day mortality rate (log-rank test, P = 0.040).In contrast, there was no significant difference in the 28-day mortality between patients who started CKRT within 12 hours and those who did not (log-rank test, P = 0.237).
Conclusion
Early CKRT initiation improved the survival of patients with sepsis-associated AKI. Initiation of CKRT should be considered as early as possible after sepsis-associated AKI onset, preferably within 6 hours.

Background:
The importance of adequate wound closure in plastic surgery cannot be overstated. With the goals of shortening the operative time and improving outcomes, various methods and devices have been introduced to enhance the speed and quality of wound closure. To simplify dermal closure with favorable outcomes, several studies have compared results between the INSORB dermal stapler and conventional dermal sutures. We hypothesized that the dermal stapler would yield satisfactory scar formation without increasing complication rates over the long term.
Methods:
This retrospective study included patients who had undergone breast reconstruction with a deep inferior epigastric perforator (DIEP) free flap between October 2019 and May 2020 at a single center. Postoperative photographs of the patients’ abdominal scars were assessed at a minimum of 248 days by three blinded attending plastic surgeons using the Vancouver Scar Scale.
Results:
A total of 108 patients who underwent DIEP-free flap reconstruction after mastectomy were included in this study. Among them, 68 patients (group 1) underwent dermal closure with the INSORB dermal stapler, while 40 patients (group 2) underwent conventional dermal sutures. No significant differences were observed between the two groups in terms of vascularity, pigmentation, pliability, scar height, or overall scar assessment. Additionally, there was no significant difference in complication rates between the two groups.
Conclusions
The INSORB dermal stapler is a valuable tool that can reduce operative time while delivering satisfactory outcomes. When used appropriately with proper training, it can mitigate perioperative complications and alleviate the surgical burden for the surgeon.

Osteoporosis and Sarcopenia 2024;10(3):95-100
The objectives of fusion surgery for spinal deformities include decompressing neural elements and achieving balanced spinal alignment. Particularly, in cases where spinal deformities coexist with osteoporosis, successful surgery requires careful consideration due to the susceptibility to fixation failure and non-union. Various efforts are being made to restore spinal alignment through surgery in osteoporotic patients. The administration of osteoporosis medications before and after surgery is effective for bony union. Additionally, appropriate selection of fusion range, rigid internal fixation, and utilization of bone substitutes play significant roles in successful fusion surgery. Although surgical treatment for spinal deformities accompanied by osteoporosis remains still challenging, we can anticipate successful outcomes with effective strategies and ongoing advancements in the future.

Clinical Psychopharmacology and Neuroscience 2023;21(1):188-196
Objective:
The Functioning Assessment Short Test (FAST) is a relatively specific test for bipolar disorders designed to assess the main functioning problems experienced by patients. This brief instrument includes 24 items assessing impairment or disability in 6 domains of functioning: autonomy, occupational functioning, cognitive functioning, financial issues, interpersonal relationships, and leisure time. It has already been translated into standardized versions in several languages. The aim of this study is to measure the validity and reliability of the Korean version of FAST (K-FAST).
Methods:
A total of 209 bipolar disorder patients were recruited from 14 centers in Korea. K-FAST, Young Mania Rating Scale (YMRS), Bipolar Depression Rating Scale (BDRS), Global Assessment of Functioning (GAF) and the World Health Organization Quality of Life Assessment Instrument Brief Form (WHOQOL-BREF) were administered, and psychometric analysis of the K-FAST was conducted.
Results:
The internal consistency (Cronbach’s alpha) of the K-FAST was 0.95. Test-retest reliability analysis showed a strong correlation between the two measures assessed at a 1-week interval (ICC = 0.97; p < 0.001). The K-FAST exhibited significant correlations with GAF (r = −0.771), WHOQOL-BREF (r = −0.326), YMRS (r = 0.509) and BDRS (r = 0.598). A strong negative correlation with GAF pointed to a reasonable degree of concurrent validity. Although the exploratory factor analysis showed four factors, the confirmatory factor analysis of questionnaires had a good fit for a six factors model (CFI = 0.925; TLI = 0.912; RMSEA = 0.078).
Conclusion
The K-FAST has good psychometric properties, good internal consistency, and can be applicable and acceptable to the Korean context.

International Journal of Stem Cells 2023;16(2):145-155
Background and Objectives:
Embryologically, mesodermal development is closely related to the development of various organs such as muscles, blood vessels, and hearts, which are the main organs that make up the body. However, treatment for mesoderm developmental disorders caused by congenital or acquired factors has so far relied on surgery and drug treatment for symptom relief, and more fundamentally, treatment for mesoderm developmental disorders is needed.
Methods:
and Results: In our study, microRNA (miRNA), which plays an important role in the mesoderm development process, was identified and the developmental function was evaluated. miRNAs consist of small nucleotides, which act as transcription factors that bind to the 3’ untranslated region and suppressed target gene expression. We constructed the human embryonic stem cell (hESC) knockout cell line and analyzed the function and characteristics of miR-5739, which plays an important role in mesoderm lineage. miR-5739 acts as a transcription factor targeting SMA, Brachyury T, Hand1, which controls muscle proliferation and differentiation, and KDR gene, which regulates vessel formation in vitro. In vivo results suggest a role in regulating muscle proliferation and differentiation. Gene ontology analysis confirmed that the miR-5739 is closely related to genes that regulate muscle and vessel proliferation and differentiation. Importantly, abnormal expression of miR-5739 was detected in somatic cells derived from patients with congenital muscle disease.
Conclusions
Our study demonstrate that miR-5739 gene function significantly affects transcriptional circuits that regu-late muscle and vascular differentiation during embryonic development.
