Background: and Purpose The accurate prediction of functional outcomes in patients with acute ischemic stroke (AIS) is crucial for informed clinical decision-making and optimal resource utilization. As such, this study aimed to construct an ensemble deep learning model that integrates multimodal imaging and clinical data to predict the 90-day functional outcomes after AIS. Methods: We used data from the Korean Stroke Neuroimaging Initiative database, a prospective multicenter stroke registry to construct an ensemble model integrated individual 3D convolutional neural networks for diffusion-weighted imaging and fluid-attenuated inversion recovery (FLAIR), along with a deep neural network for clinical data, to predict 90-day functional independence after AIS using a modified Rankin Scale (mRS) of 3–6. To evaluate the performance of the ensemble model, we compared the area under the curve (AUC) of the proposed method with that of individual models trained on each modality to identify patients with AIS with an mRS score of 3–6. Results: Of the 2,606 patients with AIS, 993 (38.1%) achieved an mRS score of 3–6 at 90 days post-stroke. Our model achieved AUC values of 0.830 (standard cross-validation [CV]) and 0.779 (time-based CV), which significantly outperformed the other models relying on single modalities: b-value of 1,000 s/mm2 (P<0.001), apparent diffusion coefficient map (P<0.001), FLAIR (P<0.001), and clinical data (P=0.004). Conclusion The integration of multimodal imaging and clinical data resulted in superior prediction of the 90-day functional outcomes in AIS patients compared to the use of a single data modality.

The Committee of Clinical Practice Guidelines of the Korean Diabetes Association (KDA) updated the previous clinical practice guidelines for Korean adults with diabetes and prediabetes and published the seventh edition in May 2021. We performed a comprehensive systematic review of recent clinical trials and evidence that could be applicable in real-world practice and suitable for the Korean population. The guideline is provided for all healthcare providers including physicians, diabetes experts, and certified diabetes educators across the country who manage patients with diabetes or the individuals at the risk of developing diabetes mellitus. The recommendations for screening diabetes and glucose-lowering agents have been revised and updated. New sections for continuous glucose monitoring, insulin pump use, and non-alcoholic fatty liver disease in patients with diabetes mellitus have been added. The KDA recommends active vaccination for coronavirus disease 2019 in patients with diabetes during the pandemic. An abridgement that contains practical information for patient education and systematic management in the clinic was published separately.

Purpose: Here, we compared the operative and perioperative outcomes between robot-assisted laparoscopic myomectomy (RALM) and abdominal myomectomy (AM) in patients with large (>10 cm) or heavy myomas (>250 g). Materials and Methods: We included 278 patients who underwent multi-port RALM (n=126) or AM (n=151) for large or heavy myomas in a tertiary care hospital between April 2019 and June 2020. The t-test, chi-square, Bonferroni’s test, and multiple linear regression were used. Results: No differences were observed in age, body mass index, parity, or history of pelvic surgery between the two groups. Myoma diameters were not different (10.8±2.52 cm vs. 11.2±3.0 cm, p=0.233), but myomas were lighter in the RALM group than in the AM group (444.6±283.14 g vs. 604.68±368.35 g, respectively, p=0.001). The RALM group had a higher proportion of subserosal myomas, fewer myomas, fewer large myomas over >3 cm, lighter myomas, and longer total operating time. However, the RALM group also had shorter hospital stay and fewer short-term complications. Estimated blood loss (EBL) was not different between the two groups. The number of removed myomas was the most significant factor (coefficient=10.89, p<0.0001) affecting the EBL. Conclusion RALM is a feasible myomectomy technique even for large or heavy myomas. RALM patients tend to have shorter hospital stays and fewer postoperative fevers within 48 hours. However, RALM has longer total operating time.

Clinical practice guidelines for gynecologic cancers have been developed by many organizations. Although these guidelines have much in common in terms of the practice of standard of care for uterine corpus cancer, practice guidelines that reflect the characteristics of patients and healthcare and insurance systems are needed for each country. The Korean Society of Gynecologic Oncology (KSGO) published the first edition of practice guidelines for gynecologic cancer treatment in late 2006; the second edition was released in July 2010 as an evidence-based recommendation. The Guidelines Revision Committee was established in 2015 and decided to produce the third edition of the guidelines as an advanced form based on evidence-based medicine, considering up-to-date clinical trials and abundant qualified Korean data. These guidelines cover screening, surgery, adjuvant treatment, and advanced and recurrent disease with respect to endometrial carcinoma and uterine sarcoma. The committee members and many gynecologic oncologists derived key questions from the discussion, and a number of relevant scientific literatures were reviewed in advance. Recommendations for each specific question were developed by the consensus conference, and they are summarized here, together with other details. The objective of these practice guidelines is to establish standard policies on issues in clinical areas related to the management of uterine corpus cancer based on the findings in published papers to date and the consensus of experts as a KSGO Consensus Statement.

BACKGROUND AND PURPOSE: Decreasing the time delay for thrombolysis, including intravenous thrombolysis (IVT) with tissue plasminogen activator and intra-arterial thrombectomy (IAT), is critical for decreasing the morbidity and mortality of patients experiencing acute stroke. We aimed to decrease the in-hospital delay for both IVT and IAT through a multidisciplinary approach that is feasible 24 h/day. METHODS: We implemented the Stroke Alert Team (SAT) on May 2, 2016, which introduced hospital-initiated ambulance prenotification and reorganized in-hospital processes. We compared the patient characteristics, time for each step of the evaluation and thrombolysis, thrombolysis rate, and post-thrombolysis intracranial hemorrhage from January 2014 to August 2016. RESULTS: A total of 245 patients received thrombolysis (198 before SAT; 47 after SAT). The median door-to-CT, door-to-MRI, and door-to-laboratory times decreased to 13 min, 37.5 min, and 8 min, respectively, after SAT implementation (P<0.001). The median door-to-IVT time decreased from 46 min (interquartile range [IQR] 36–57 min) to 20.5 min (IQR 15.8–32.5 min; P<0.001). The median door-to-IAT time decreased from 156 min (IQR 124.5–212.5 min) to 86.5 min (IQR 67.5–102.3 min; P<0.001). The thrombolysis rate increased from 9.8% (198/2,012) to 15.8% (47/297; P=0.002), and the post-thrombolysis radiological intracranial hemorrhage rate decreased from 12.6% (25/198) to 2.1% (1/47; P=0.035). CONCLUSIONS: SAT significantly decreased the in-hospital delay for thrombolysis, increased thrombolysis rate, and decreased post-thrombolysis intracranial hemorrhage. Time benefits of SAT were observed for both IVT and IAT and during office hours and after-hours.

OBJECTIVE: This study aimed to evaluate the efficacy and safety of pegylated liposomal doxorubicin (PLD) with or without carboplatin in Korean patients with recurrent ovarian cancer (ROC), fallopian tube, or primary peritoneal cancer. METHODS: This retrospective study included 52 patients with ROC, fallopian tube, or primary peritoneal cancer who received PLD (50 mg/m²) between 1(st) December 2014 and 31(th) July 2016. RESULTS: The mean number of chemotherapy cycles was 3.8 (range, 2 to 9) in the PLD monotherapy group and 7 (range, 2 to 13) in the PLD combined with carboplatin (PLD-C) group. In overall response rates and clinical beneficial rates, PLD monotherapy group shows 5.0% and 17.5%, and PLD-C group shows 33.3% and 75.0%. The mean progression-free survival (PFS) was 5 and 13 months in the PLD monotherapy and PLD-C groups, respectively. At 6 months after treatment initiation, absence of disease progression was confirmed in 6 (15%) and 10 (83.3%) patients in the PLD monotherapy and PLD-C groups. Hematological adverse events (e.g., neutropenia and thrombocytopenia) were more common in the PLD-C group (P<0.001, P=0.004). The incidence of anemia and non-hematological adverse events, including mucositis, hand-foot syndrome, and allergic reactions, was similar in both groups. CONCLUSION: This study demonstrated the efficacy and safety of PLD monotherapy and PLD-C combination in Korean patients with ROC. This study would be helpful to consider the degree of worry about side effects and treatment expectations after treatment. Further retrospective studies with larger samples are required to confirm the efficacy of PLD monotherapy in Asian patients with platinum-resistant ROC.

BACKGROUND AND OBJECTIVES: Despite significant advances in the treatment of acute myocardial infarction (MI), the prevention of sudden cardiac death (SCD), the most common mode of death in patients with MI, remains challenging. Furthermore, previous Korean MI registries did not address the issue of post-MI SCD. Additional risk stratifiers of post-MI SCD are still required to compensate for the limitation of using left ventricular ejection fraction to predict lethal arrhythmic events. SUBJECTS AND METHODS: We designed the first Korean prospective nationwide multicenter registry primarily focused on SCD; the Korean noninvasive Risk Evaluation study for sudden cardiac DEath From INfarction or heart failurE (K-REDEFINE). The registry consists of 2 groups of patients presenting with (1) acute MI or (2) acute heart failure (HF) at 25 tertiary referral cardiovascular centers. The primary endpoint of the MI group study of K-REDEFINE registry is the incidence and risk factors of post-MI SCD. In particular, the association between the risk of SCD and non-invasive Holter-based electrocardiogram (ECG) variables will be evaluated, such as T-wave alternans (marker of repolarization heterogeneity) and heart rate turbulence/variability (a marker of autonomic function). Other secondary study outcomes include atrioventricular arrhythmias, HF-related admission, repeated myocardial ischemic events, stroke, and overall deaths. CONCLUSION AND PERSPECTIVE: The K-REDEFINE registry will provide new prospects for the better management of MI patients with high risk of SCD by clarifying the burden and predictors of SCD and the clinical utility of various non-invasive ambulatory ECG-based variables in risk stratification for SCD in this patient population.
