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.

Rare endocrine diseases are complex conditions that require lifelong specialized care due to their chronic nature and associated long-term complications. In Korea, a lack of nationwide data on clinical practice and outcomes has limited progress in patient care. Therefore, the Multicenter Networks for Ideal Outcomes of Pediatric Rare Endocrine and Metabolic Disease (OUTSPREAD) study was initiated. This study involves 30 centers across Korea. The study aims to improve the long-term prognosis of Korean patients with rare endocrine diseases by collecting comprehensive clinical data, biospecimens, and patient-reported outcomes to identify complications and unmet needs in patient care. Patients with childhood-onset pituitary, adrenal, or gonadal disorders, such as craniopharyngioma, congenital adrenal hyperplasia (CAH), and Turner syndrome were prioritized. The planned enrollment is 1,300 patients during the first study phase (2022–2024). Clinical, biochemical, and imaging data from diagnosis, treatment, and follow-up during 1980–2023 were retrospectively reviewed. For patients who agreed to participate in the prospective cohort, clinical data and biospecimens will be prospectively collected to discover ideal biomarkers that predict the effectiveness of disease control measures and prognosis. Patient-reported outcomes, including quality of life and depression scales, will be evaluated to assess psychosocial outcomes. Additionally, a substudy on CAH patients will develop a steroid hormone profiling method using liquid chromatography-tandem mass spectrometry to improve diagnosis and monitoring of treatment outcomes. This study will address unmet clinical needs by discovering ideal biomarkers, introducing evidence-based treatment guidelines, and ultimately improving long-term outcomes in the areas of rare endocrine and metabolic diseases.

Background:
While Korea maintains a low prevalence of human immunodeficiency virus (HIV), the number of newly diagnosed cases has been steadily rising, reaching approximately 1,000 annually in recent years. The 2022 annual report from the Korea Disease Control and Prevention Agency revealed that women living with HIV (WLWH) constitute 6.4% of the total confirmed people living with the HIV population, totaling 1,219 individuals. Despite this, only a few studies have focused on WLWH in Korea. This study aims to analyze the epidemiological and clinical characteristics of WLWH in Korea.
Materials and Methods:
We retrospectively collected data by reviewing the medical records of all WLWH who visited 10 urban referral hospitals across Korea between January 2005 and May 2023.
Results:
A total of 443 WLWH were enrolled in this study. The predominant risk exposure was heterosexual contact, with 235 (53%) participants either married or cohabiting with a male partner at their initial clinic visit. Among the participants, 334 (77.7%) were Korean, 27 (6.1%) were Southeast Asian, and 19 (4.3%) were African. Antiretroviral therapy was initiated by 404 WLWH (91.2%). We observed 118 pregnancies in WLWH following their HIV diagnosis, resulting in 78 live births (66.1%), 18 induced abortions (15.2%), 10 pre-viable fetal losses (8.5%), and four stillbirths (3.4%). Over a cumulative follow-up duration of 3,202.1 years, the incidence rates of breast and cervical cancers were both 2.18 per 1,000 person-years. Additionally, the incidence rates of pelvic inflammatory disease, cervical intraepithelial neoplasm (above grade II), and osteoporosis were 4.67, 11.21, and 13.39 per 1,000 patient-years, respectively.
Conclusion
This is the first multicenter study to investigate the clinical and epidemiological characteristics of WLWH in Korea. The incidence and prevalence of diseases in women, including breast cancer, cervical cancer, and chronic comorbidities, are high in WLWH in Korea; therefore, further research and efforts are needed to manage these diseases.

Lipomas, the most common soft-tissue mesenchymal neoplasms in adults, are characterized by the proliferation of mature white adipocytes without cytologic atypia. Lipomas are rarely observed in the head and neck region. We present a case of resection and orthognathic surgical removal of an intramuscular lipoma of the mandible with involvement of the mandibular ramus and condylar head and neck. An 18-year-old female patient was referred to our hospital for orthognathic surgery for the management of facial asymmetry and mandibular prognathism. The patient did not present with facial swelling, pain, or temporomandibular dysfunction; however, on radiographic examination, including cone-beam computed tomography and magnetic resonance imaging, an infiltrative fatty lesion was observed in the masticator space inside the right mandible, and the adjacent mandible exhibited bone thinning and deformity. Resection of the lipoma was performed along with orthognathic surgery, including a Le Fort I osteotomy for the maxilla and bilateral sagittal split ramus osteotomy (BSSRO). In this case, because the ramus was split using BSSRO, accessing the lipoma intraorally was easy.Consequently, aesthetic scarring was avoided, and no complications, such as unfavorable splitting or pathologic fracture, occurred. Although recurrence has not been observed about 1 year, long-term follow-up should be performed.

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.
