A higher regulatory T cells/helper T cells ratio is associated with an unfavorable prognosis and loco-regional recurrence pattern in gastric cardia cancer.

AI-assisted CCL activation using initial ECG is feasible. If such a policy is implemented, it would be reasonable to expect some reduction in D2B time, medical cost, and 1-year mortality.

Flexible amorphous silicon (a-Si:H) solar cells with high photoconversion efficiency (PCE) are demonstrated by embedding hexagonal pyramid nanostructures below a Ag/indium tin oxide (ITO) reflector. The nanostructures constructed by nanoimprint lithography using soft materials allow the top ITO electrode to spontaneously form parabolic nanostructures. Nanoimprint lithography using soft materials is simple, and is conducted at low temperature. The resulting structure has excellent durability unde

At 12 months after extracorporeal membrane oxygenation therapy, nearly half survivors experienced quality of life worsening such as unemployment, decreased income, and new disability. Additionally, among the three factors, acquiring a new disability might significantly increase the 3-year mortality. This is the first study to report the association between changes in the quality of life and long-term prognosis in extracorporeal membrane oxygenation survivors.

At 12 months after ECMO therapy, 11.3% of ECMO survivors were newly diagnosed with CRDs. Patients who underwent ECMO therapy for ARDS or respiratory failure were associated with a higher incidence of newly diagnosed post-ECMO CRD compared to those who underwent ECMO for other causes. Additionally, post-ECMO CRDs were associated with a higher 5-year all-cause mortality. Our results suggest that ECMO survivors with newly diagnosed post-ECMO CRD might be a high-risk group requiring dedicated interv

In South Korea, the prevalence of ECMO treatment has increased gradually and continuously between 2005 and 2018. There was a significant increase in the prevalence of ECMO treatment for ARDS or respiratory failure. Our results support that ECMO treatment indications have been expanding, and ECMO will become vital for treating critically ill patients in the future.

ECMO therapy initiated during a weekend was associated with a slightly increased risk of 60-day mortality compared to that associated with ECMO therapy initiated on a weekday. This association was more evident in patients who received ECMO therapy that started on a Saturday. Further studies are needed to confirm these findings.

Electrocardiogram (ECG) changes after primary percutaneous coronary intervention (PCI) in ST-segment elevation myocardial infarction (STEMI) patients are associated with prognosis. This study investigated the feasibility of predicting left ventricular (LV) dysfunction in STEMI patients using an artificial intelligence (AI)-enabled ECG algorithm developed to diagnose STEMI. Serial ECGs from 637 STEMI patients were analyzed with the AI algorithm, which quantified the probability of STEMI at variou

In South Korea, beta-blockers exhibited potential benefits in lowering the incidence of COVID-19 among hypertensive patients. Furthermore, CCBs may lower the hospital mortality rate among hypertensive COVID-19 patients. These findings were also applied to the general adult population, regardless of hypertension.

Purpose: The prognosis of advanced hepatocellular carcinoma (HCC) is very grave. The most effective method to improve the survival rate of HCC patients is early diagnosis and curative resection. The aim of this study is to investigate risk factors affecting the recurrence of HCC after curative resection. Methods: We retrospectively analyzed 287 HCC patients who underwent surgical resection at Severence Hospital between Jan. 1998 and Dec. 2003. They consisted of 222 males and 65 females whose med
