RESUMEN
Background@#Perioperative adverse cardiac events (PACE), a composite of myocardial infarction, coronary revascularization, congestive heart failure, arrhythmic attack, acute pulmonary embolism, cardiac arrest, and stroke during 30-day postoperative period, is associated with long-term mortality, but with limited clinical evidence. We compared long-term mortality with PACE using data from nationwide multicenter electronic health records. @*Methods@#Data from 7 hospitals, converted to Observational Medical Outcomes Partnership Common Data Model, were used. We extracted records of 277,787 adult patients over 18 years old undergoing non-cardiac surgery for the first time at the hospital and had medical records for more than 180 days before surgery. We performed propensity score matching and then an aggregated meta‑analysis. @*Results@#After 1:4 propensity score matching, 7,970 patients with PACE and 28,807 patients without PACE were matched. The meta‑analysis showed that PACE was associated with higher one-year mortality risk (hazard ratio [HR]: 1.33, 95% CI [1.10, 1.60], P = 0.005) and higher three-year mortality (HR: 1.18, 95% CI [1.01, 1.38], P = 0.038). In subgroup analysis, the risk of one-year mortality by PACE became greater with higher-risk surgical procedures (HR: 1.20, 95% CI [1.04, 1.39], P = 0.020 for low-risk surgery; HR: 1.69, 95% CI [1.45, 1.96], P < 0.001 for intermediate-risk; and HR: 2.38, 95% CI [1.47, 3.86], P = 0.034 for high-risk). @*Conclusions@#A nationwide multicenter study showed that PACE was significantly associated with increased one-year mortality. This association was stronger in high-risk surgery, older, male, and chronic kidney disease subgroups. Further studies to improve mortality associated with PACE are needed.
RESUMEN
Background/Aims@#Bleeding events after percutaneous coronary intervention (PCI) have important prognostic implications. Data on the influence of an abnormal ankle-brachial index (ABI) on both ischemic and bleeding events in patients undergoing PCI are limited. @*Methods@#We included patients who underwent PCI with available ABI data (abnormal ABI, ≤ 0.9 or > 1.4). The primary endpoint was the composite of all-cause death, myocardial infarction (MI), stroke, and major bleeding. @*Results@#Among 4,747 patients, an abnormal ABI was observed in 610 patients (12.9%). During follow-up (median, 31 months), the 5-year cumulative incidence of adverse clinical events was higher in the abnormal ABI group than in the normal ABI group: primary endpoint (36.0% vs. 14.5%, log-rank test, p < 0.001); all-cause death (19.4% vs. 5.1%, log-rank test, p < 0.001); MI (6.3% vs. 4.1%, log-rank test, p = 0.013); stroke (6.2% vs. 2.7%, log-rank test, p = 0.001); and major bleeding (8.9% vs. 3.7%, log-rank test, p < 0.001). An abnormal ABI was an independent risk factor for all-cause death (hazard ratio [HR], 3.05; p < 0.001), stroke (HR, 1.79; p = 0.042), and major bleeding (HR, 1.61; p = 0.034). @*Conclusions@#An abnormal ABI is a risk factor for both ischemic and bleeding events after PCI. Our study findings may be helpful in determining the optimal method for secondary prevention after PCI.

RESUMEN
Small cell carcinoma is derived from APUDcells of any parts of the body. Usually the cases are discovered in the lungs and have poor prognosis. Small cell carcinoma has been increasingly reported in various organ outside the lungs, such as the larynx, thymus, esophagus, stomach, pancreas, uterine cervix, and prostate. Primary small cell carcinoma of the stomach is extremly rare. The histology of the tumor was similar to that of ordinary small cell carcinoma of the lung, and the secretory granules were identified by electron microscopy. We report a patient with gastric pure small cell carcinoma who treated by a radical total gastrectomy and chemotherapy.
