Background and Objectives: Outcomes of deferring percutaneous coronary intervention (PCI) without invasive physiologic assessment for intermediate coronary lesions is uncertain.We sought to compare long-term outcomes between medical treatment and PCI of intermediate lesions without invasive physiologic assessment. Methods: A total of 899 patients with intermediate coronary lesions between 50% and 70% diameter-stenosis were randomized to the conservative group (n=449) or the aggressive group (n=450). For intermediate lesions, PCI was performed in the aggressive group, but was deferred in the conservative group. The primary endpoint was major adverse cardiac events (MACE, a composite of all-cause death, myocardial infarction [MI], or ischemia-driven any revascularization) at 3 years. Results: The number of treated lesions per patient was 0.8±0.9 in the conservative group and 1.7±0.9 in the aggressive group (p=0.001). At 3 years, the conservative group had a significantly higher incidence of MACE than the aggressive group (13.8% vs. 9.3%; hazard ratio [HR], 1.49; 95% confidence interval [CI], 1.00–2.21; p=0.049), mainly driven by revascularization of target intermediate lesion (6.5% vs. 1.1%; HR, 5.69; 95% CI, 2.20–14.73;p<0.001). Between 1 and 3 years after the index procedure, compared to the aggressive group, the conservative group had significantly higher incidence of cardiac death or MI (3.2% vs.0.7%; HR, 4.34; 95% CI, 1.24–15.22; p=0.022) and ischemia-driven any revascularization. Conclusions For intermediate lesions, medical therapy alone, guided only by angiography, was associated with a higher risk of MACE at 3 years compared with performing PCI, mainly due to increased revascularization.

Objective: The emergency department (ED) serves as the initial point of contact for many sepsis patients, but crowding can affect the timely delivery of essential interventions, such as antibiotics. This paper explores the relationship between antibiotics administration and ED crowding in the context of sepsis management. Methods: This single-center study at a tertiary care hospital included adult patients aged 18 and above who visited the emergency department from January 2018 to December 2022. Patients showing signs of septic shock upon arrival were selected as the study population. This study examined factors such as emergency department occupancy, antibiotic administration time, and their correlation with timely antibiotic treatment. Results: This study of 839 adult patients with septic shock found a weak correlation (P=0.107) between the time to antibiotic administration and department occupancy. Delayed antibiotic administration was observed when the occupancy exceeded 100%. On the other hand, there was no significant correlation between antibiotic administration within one hour and department occupancy. Conclusion Various factors, such as ED bed occupancy, medical staffing, resource allocation, and patient acuity, must be considered when comprehensively evaluating the impact of ED overcrowding on treating septic shock and other conditions.

Objective: This study examined the characteristics of the patients taking poison intentionally at the pre-hospital stage to prevent it at the community level. Methods: We retrospectively reviewed the data that had been reported to fire stations from January 2017 to December 2018. This data included sex, age, occupation, the season of the year, time, place, methods, alcohol ingestion, transferred to the hospital or not, and we examined how taking poison had an effect on the suicide success rate. Results: The subjects were a total of 1,356 patients who had been reported to fire stations due to intentionally taking poison. Forty-five point five percent of them were male, and 54.5% were female. The most common method of intentional taking poison was sedatives (58.3%), followed by pesticides (24.6%), antidepressants (19.0%), and other methods (12.6%). The home place was preferred more than any other places. The suicide success rate was 2.1% in males and 1.4% in females. For the age groups, those patients 40-64 years old tried taking poison much more than the other age groups. In the aspect of the season of the year, summer was the highest season for taking poison, at 30.3%. The daytime was more preferred than the night time. Conclusion In this study, we analyzed the characteristics of the pre-hospital intentional poisoning cases according to gender, age, occupation, season of the year, time, and between the transferred and the untransferred groups. Efforts should be made in cooperation with the community to prevent suicide attempts by intentionally taking poison.

BACKGROUND AND OBJECTIVES: There are limited data regarding the clinical efficacy of the proximal optimization technique (POT) in the treatment of coronary bifurcation lesions. We investigated the influence of POT on the clinical outcomes of patients with coronary bifurcation lesions. METHODS: We enrolled a total of 1,191 patients with a bifurcation lesion with a side branch (SB) diameter ≥2.5 mm treated with a drug-eluting stent from 18 centers between January 2003 and December 2009. The primary outcome was major adverse cardiac events (MACEs: cardiac death, myocardial infarction or target lesion revascularization [TLR]). We performed one-to-many (1:N) propensity score matching with non-fixed matching ratio. RESULTS: POT was performed in 252 patients. During follow-up (median 37 months), the incidence of MACE was lower in the POT group than it was in the non-POT group (adjusted hazard ratio, 0.43; 95% confidence interval [CI], 0.24–0.79; p=0.006). After propensity score matching, these were 0.34; 95% CI, 0.17–0.69; p=0.003 for MACE and 0.37; 95% CI, 0.17–0.78; p=0.01 for TLR. The use of POT was associated with significantly lower TLR in patients treated without kissing ballooning, but was not in those who underwent kissing ballooning (p for interaction=0.03). CONCLUSIONS: In coronary bifurcation lesions with a large SB, POT may be beneficial to improve long-term clinical outcome, particularly in patients treated without kissing ballooning during the procedure.

OBJECTIVE: Burr hole craniostomy and closed-system drainage (BCD) is a common surgical procedure in the field of neurosurgery. However, complications following BCD have seldom been reported. The purpose of this study was to report our experiences regarding complications following BCD for subdural lesions. METHODS: A retrospective study of all consecutive patients who underwent BCD for presumed subdural lesions at one institute since the opening of the hospital was performed. RESULTS: Of the 395 patients who underwent BCD for presumed subdural lesions, 117 experienced surgical or nonsurgical complications. Acute intracranial hemorrhagic complications developed in 14 patients (3.5%). Among these, 1 patient died and 5 patients had major morbidities. Malposition of the drainage catheter in the brain parenchyma occurred in 4 patients, and opposite-side surgery occurred in 2 patients. Newly developed seizures after BCD occurred in 8 patients (2.0%), five of whom developed the seizures in relation to new brain lesions. Eighty-eight patients (22.3%) suffered from nonsurgical complications after BCD. Pulmonary problems (7.3%) were the most common nonsurgical complications, followed by urinary problems (5.8%), psychologic problems (4.3%), and cognitive impairments (3.8%). CONCLUSION: The incidence of complications after BCD for subdural lesions is higher than previously believed. In particular, catastrophic complications such as acute intracranial hematomas and surgical or management errors occur at rates that cannot be ignored, possibly causing medico-legal problems. Great caution must be taken during surgery and the postoperative period, and these complications should be listed on the informed consent form before surgery.

PURPOSE: Hypoxic-ischemic encephalopathy is a significant cause of neonatal morbidity and mortality. Erythropoietin (EPO) is emerging as a therapeutic candidate for neuroprotection. Therefore, this study was designed to determine the neuroprotective role of recombinant human EPO (rHuEPO) and the possible mechanisms by which mitogen-activated protein kinase (MAPK) signaling pathway including extracellular signal-regulated kinase (ERK1/2), JNK, and p38 MAPK is modulated in cultured cortical neuronal cells and astrocytes. METHODS: Primary neuronal cells and astrocytes were prepared from cortices of ICR mouse embryos and divided into the normoxic, hypoxia (H), and hypoxia-pretreated with EPO (H+EPO) groups. The phosphorylation of MAPK pathway was quantified using western blot, and the apoptosis was assessed by caspase-3 measurement and terminal deoxynucleotidyl transferase dUTP nick end labeling assay. RESULTS: All MAPK pathway signals were activated by hypoxia in the neuronal cells and astrocytes (P<0.05). In the neuronal cells, phosphorylation of ERK-1/-2 and apoptosis were significantly decreased in the H+EPO group at 15 hours after hypoxia (P<0.05). In the astrocytes, phosphorylation of ERK-1/-2, p38 MAPK, and apoptosis was reduced in the H+EPO group at 15 hours after hypoxia (P<0.05). CONCLUSION: Pretreatment with rHuEPO exerts neuroprotective effects against hypoxic injury reducing apoptosis by caspase-dependent mechanisms. Pathologic, persistent ERK activation after hypoxic injury may be attenuateed by pretreatment with EPO supporting that EPO may regulate apoptosis by affecting ERK pathways.
