Abstract
OBJECTIVEA thorough investigation of the long-term outcomes and chronological changes of multimodal treatments for petroclival meningiomas is required to establish optimal management strategies. The authors retrospectively reviewed the long-term clinical outcomes of patients with petroclival meningioma according to various treatments, including various surgical approaches, and they suggest treatment strategies based on 30 years of experience at a single institution.METHODSNinety-two patients with petroclival meningiomas were treated surgically at the authors’ institution from 1986 to 2015. Patient demographics, overall survival, local tumor control rates, and functional outcomes according to multimodal treatments, as well as chronological change in management strategies, were evaluated. The mean clinical and radiological follow-up periods were 121 months (range 1–368 months) and 105 months (range 1–348 months), respectively.RESULTSA posterior transpetrosal approach was most frequently selected and was followed in 44 patients (48%); a simple retrosigmoid approach, undertaken in 30 patients, was the second most common. The initial extent of resection and following adjuvant treatment modality were classified into 3 subgroups: gross-total resection (GTR) only in 13 patients; non-GTR treatment followed by adjuvant radiosurgery or radiation therapy (non-GTR+RS/RT) in 56 patients; and non-GTR without adjuvant treatment (non-GTR only) in 23 patients. The overall progression-free survival rate was 85.8% at 5 years and 81.2% at 10 years. Progression or recurrence rates according to each subgroup were 7.7%, 12.5%, and 30.4%, respectively.CONCLUSIONSThe authors’ preferred multimodal treatment strategy, that of planned incomplete resection and subsequent adjuvant radiosurgery, is a feasible option for the management of patients with large petroclival meningiomas, considering both local tumor control and postoperative quality of life.

Abstract
<sec> <title>BACKGROUND</title> Idiopathic pulmonary fibrosis (IPF) and chronic obstructive pulmonary disease (COPD) share common risk factors. They could therefore be expressed in a single patient. However, the prevalence, clinical characteristics and prognosis of individuals with comorbid IPF and COPD are not known. </sec> <sec> <title>METHOD</title> From 2003 to 2007, the Korean Interstitial Lung Disease Study Group created a register for idiopathic interstitial pneumonia using 2002 ATS/ERS (American Thoracic Society/European Respiratory Society) criteria. Of the 1546 IPF patients assessed, 143 had decreased lung function consistent with COPD (IPF-COPD). COPD was diagnosed based on age (≥40 years) and pulmonary function (forced expiratory volume in 1 sec [FEV1]/forced vital capacity [FVC] ratio < 0.7). </sec> <sec> <title>RESULTS</title> The median age of the IPF-COPD group was 71.0 years (interquartile range 66.0-76.0); most patients were male (88.1%). FVC (%) was significantly higher in the IPF-COPD group; however, FEV1 (%) was significantly lower in the IPF-COPD group (P < 0.001). Diffusing capacity of the lung for carbon monoxide (DLCO) was not significantly different between the two groups. In survival analysis, age and FVC (%), but not COPD, were significantly associated with prognosis (respectively P = 0.003, 0.001 and 0.401). COPD severity was also not related to prognosis (P = 0.935). </sec> <sec> <title>CONCLUSION</title> The prevalence of IPF-COPD was estimated to be ∼9.2% among all IPF patients; prognosis of patients with IPF-COPD was not worse than those with IPF alone. </sec>.

Abstract
Carbon shell areal density measurements from many types of inertial confinement fusion implosions at the National Ignition Facility (NIF) demonstrate that the final state of the outside portion of the shell is set primarily by capsule coast time, the coasting period between main laser shut off and peak fusion output. However, the fuel areal density does not correlate with the increasing carbon compression. While two-dimensional (2D) radiation-hydrodynamic simulations successfully capture the carbon compression, energy must be added to the simulated fuel-ice layer to reproduce fuel areal density measurements. The data presented demonstrates that the degradation mechanisms that reduce the compressibility of the fuel do not reduce the compressibility of the ablator.

[PMID: 31978882 DOI: 10.3171/2019.11.jns192381] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2019] [Accepted: 11/15/2019] [Indexed: 11/06/2022]
Abstract
OBJECTIVE In this double-blind randomized trial, the necessity of preoperative steroid administration in patients without adrenal insufficiency (AI) undergoing endoscopic transsphenoidal surgery (ETSS) for pituitary adenoma was evaluated. METHODS Forty patients with and without AI, defined as a peak cortisol level > 18 µg/dl on the insulin tolerance test or rapid adrenocorticotropic hormone (ACTH) test, undergoing ETSS for nonfunctioning pituitary adenomas were randomly allocated to treatment with either 100 mg of preoperative hydrocortisone (group HC, n = 20) or normal saline (group C, n = 20). The patients with pituitary apoplexy, the use of a drug within the last 3 months that could affect the hypothalamic-pituitary-adrenal axis, or a previous history of brain or adrenal surgery were excluded. Intraoperative cortisol and ACTH levels were measured after anesthesia induction, dura incision, and tumor removal, and at the end of surgery. Intraoperative hypotension, early postoperative AI, and postoperative 3-month pituitary function were investigated. RESULTS Intraoperative serum cortisol levels were significantly higher in the HC group than in the C group after anesthesia induction (median 69.0 µg/dl [IQR 62.2-89.6 µg/dl] vs 12.7 µg/dl [IQR 8.4-18.2 µg/dl], median difference 57.5 µg/dl [95% CI 33.0-172.9 µg/dl]), after dura incision (median 53.2 µg/dl [IQR 44.9-63.8 µg/dl] vs 6.4 [IQR 4.8-9.2 µg/dl], median difference 46.6 µg/dl [95% CI 13.3-89.2 µg/dl]), after tumor removal (median 49.5 µg/dl [IQR 43.6-62.4 µg/dl] vs 9.2 µg/dl [IQR 5.75-16.7 µg/dl], median difference 39.4 µg/dl [95% CI 0.3-78.1 µg/dl]), and at the end of surgery (median 46.9 µg/dl [IQR 40.1-63.4 µg/dl] vs 16.9 µg/dl [IQR 12.1-23.2 µg/dl], median difference 32.2 µg/dl [95% CI -42.0 to 228.1 µg/dl]). Serum ACTH levels were significantly lower in group HC than in group C after anesthesia induction (median 3.9 pmol/L [IQR 1.7-5.2 pmol/L] vs 6.9 pmol/L [IQR 3.9-11.9 pmol/L], p = 0.007). No patient showed intraoperative hypotension due to AI. Early postoperative AI was observed in 3 and 5 patients in groups HC and C, respectively. The postoperative 3-month pituitary hormone outcomes including ACTH deficiency were not different between groups. CONCLUSIONS Preoperative steroid administration may be unnecessary in patients without AI undergoing ETSS for nonfunctioning pituitary adenomas. However, a further large-scale study is needed to determine whether preoperative steroid administration has a significant impact on clinically meaningful events such as perioperative AI and postoperative 3-month ACTH deficiency in these patients.Korean Clinical Trial Registry no.: KCT0002426 (https://cris.nih.go.kr/cris/).

Abstract
OBJECTIVE The aim of this study was to determine how gait speed and frontal lobe functionsin community-dwelling older adults in Korea. DESIGN This was a cross-sectional study. SETTING The study used data from the Korean Frailty and Aging Cohort Survey (KFACS), a multi-center longitudinal study addressing 10 centers across urban, rural, and suburban communities in Korea, between 2016 and 2017. PARTICIPANTS A total of 1552 older adults who underwent both gait speed tests and cognitive functions tests during the investigation of the KFACS. MEASUREMENTS Gait speed was assessed by asking participants to walk from a starting point to a point 4 meters away at a normal gait. Cognitive functions were evaluated using various standardized cognitive functions tests. RESULTS Gait speed was slower when participants were older or less educated The percentage of women, higher BMI, people with lower incomes, singles, smokers, and drinkers was high in the slower gait group. Also, all cognitive function scores were low and depression score was high in the group with slower walking speed. The slower walking speed showed low physical activity score and high prevalence of hypertension, osteoarthritis and osteoporosis. Among the seven cognitive functions (MMSE, memory, TMT, Recall, Recognition, digit span, and Fab), only TMT showed no significant difference between different gait speed groups. The other six cognitive functions showed higher results in the fastest gait speed group (T3), Participants in middle gait speed group (T2) also showed higher results in five of the seven cognitive function scores as well (Memory, Recall, Recognition, digit span, and Fab). CONCLUSION In this study, we found correlation between the slower gait speeds and the decrease in cognitive function, and especially the frontal lobe dysfunction was most prominent of all cognitive dysfunctions.

Abstract
Inertial fusion implosions are diagnosed using γ rays to characterize the implosion physics or measure basic nuclear properties, including cross sections. For the latter, previously reported measurements at laser facilities using gas Cherenkov detectors are limited by a large systematic uncertainty in the detector response. We present a novel in situ calibration technique using neutron inelastic scattering, which we apply to the new GCD-3 detector. The calibration accuracy is improved by ∼3× over the previous method.

Abstract
OBJECTIVES The International Council of Nurses supports the development of International Classification for Nursing Practice® (ICNP®) catalogues to support the construction of electronic health records and evidence-based practice. Such a catalogue is needed for inpatient falls. METHODS The ICNP®-Based Inpatient Fall-Prevention Catalogue ('The Catalogue') was developed following the six steps recommended by the International Council of Nurses: (1) identifying inpatient falls as a priority, (2) gathering relevant concepts from 10 international guidelines and comparing locally defined sets of fall-prevention terms, (3) mapping the concepts to the ICNP® terminology, (4) identifying new concepts, (5) conducting a clinical face validation with a 12-member panel and finalizing The Catalogue and (6) setting a strategy for dissemination. The high-level structure of the International Classification for Patient Safety was used as a theoretical framework. RESULTS Eighteen nursing care elements and 141 terms were identified. A local vocabulary set had 89 terms (63.1%) that all corresponded to the identified terms. The exact and post-coordination mapping rates to the ICNP® were 75% and 40.6% for assessment/diagnosis/outcomes and interventions, respectively. The 54 new terms corresponded to 52 primitive concepts. An external review of The Catalogue showed that it had adequate understandability and validity. However, one-third of assessments/diagnoses/outcomes and one-fourth of interventions were not found in a tertiary hospital practice. CONCLUSION A fall-prevention catalogue has been developed based on evidence and a theoretical framework and also clinically validated. IMPLICATION FOR NURSING AND HEALTH POLICY The Catalogue is a standardized interface terminology and content subset in any electronic health records system that can directly deliver evidence on fall prevention. It can also be used as an informatics tool to aggregate, analyse, interpret and compare nursing data worldwide.

Abstract
OBJECTIVE The natural history and proper algorithm for follow-up testing of nonfunctioning pituitary adenomas (PAs) are not well known, despite their relatively high prevalence. The aim of this study was to suggest the optimal follow-up algorithm for nonfunctioning PAs based on their natural history. METHODS The authors followed up 197 patients with nonfunctioning PAs that had not been treated (including surgery and radiation therapy) at the time of detection, in a single center, between March 2000 and February 2017. They conducted a hormone test, visual field test, and MRI at the time of diagnosis and yearly thereafter. RESULTS The overall median follow-up duration was 37 months. Microadenomas (n = 38) did not cause visual disturbance, pituitary apoplexy, or endocrine dysfunction. The incidence of patients with tumor volume growth ≥ 20% was higher for macroadenomas than microadenomas (13.8 vs 5.0 per 100 person-years [PYs], p = 0.002). The median time to any tumor growth was 4.8 years (95% CI 3.4-4.8 years) for microadenomas and 4 years (95% CI 3.3-4.2 years) for macroadenomas. The overall incidence of worsening visual function was 0.69 per 100 PYs. Patients with a tumor volume growth rate ≥ 0.88 cm3/year (n = 20) had a higher incidence of worsening visual function (4.69 vs 0.30 per 100 PYs, p < 0.001). The tumor growth rate of all microadenomas was < 0.88 cm3/year. The median time to tumor growth ≥ 20% was 3.3 years (95% CI 1.8-3.9 years) in patients with a tumor growth rate ≥ 0.88 cm3/year and 4.9 years (95% CI 4.6-7.2 years) in patients with a tumor growth rate < 0.88 cm3/year. CONCLUSIONS The authors have devised a follow-up strategy based on the tumor volume growth rate as well as initial tumor volume. In patients with microadenomas, the next MRI study can be performed at 3 years. In patients with macroadenomas, the second MRI study should be performed between 6 months and 1 year to assess the tumor growth rate. In patients with a tumor growth rate ≥ 0.88 cm3/year, the MRI study should be performed within 2 years. In patients with a tumor growth rate < 0.88 cm3/year, the MRI study can be delayed until 4 years.

Abstract
The Gamma Reaction History (GRH) diagnostic located at the National Ignition Facility (NIF) measures time resolved gamma rays released from inertial confinement fusion experiments by converting the emitted gamma rays into Cherenkov light. Imploded capsules have a bright 4.4 MeV gamma ray from fusion neutrons inelastically scattering with carbon atoms in the remaining ablator. The strength of the 4.4 MeV gamma ray line is proportional to the capsule's carbon ablator areal density and can be used to understand the dynamics and energy budget of a carbon-based ablator capsule implosion. Historically, the GRH's four gas cells use the energy thresholding from the Cherenkov process to forward fit an estimation of the experiment's complete gamma ray spectrum by modeling the surrounding environment in order to estimate the 4.4 MeV neutron induced carbon gamma ray signal. However, the high number of variables, local minima, and uncertainties in detector sensitivities and relative timing had prevented the routine use of the forward fit to generate carbon areal density measurements. A new, more straightforward process of direct subtraction of deconvolved signals was developed to simplify the extraction of the carbon areal density. Beryllium capsules are used as a calibration to measure the capsule environment with no carbon signal. The proposed method is then used to appropriately subtract and isolate the carbon signal on shots with carbon ablators. The subtraction algorithm achieves good results across all major capsule campaigns, achieving similar results to the forward fit. This method is now routinely used to measure carbon areal density for NIF shots.

Abstract
PURPOSE The utility of endoscopic endonasal skull base surgery (EES) in various pathologic entities in adults has been published in the literature. However, the role of EES in children has not been clearly elucidated. We evaluated the feasibility of EES in children with brain tumors. METHODS We retrospectively reviewed clinical features, surgical outcomes, and complications in children who underwent EES for intracranial and skull base tumors at a single institution from July 2010 to October 2018. RESULTS A total of 82 patients underwent EESs for 77 intracranial and 5 skull base bony tumors. The mean age at diagnosis was 11.4 years (range 4-18 years), and the mean follow-up period was 46.8 months. The most common tumors were craniopharyngioma in the intracranial tumor and chordoma in the skull base. Gross total resection was the goal of surgery in 55 patients and achieved in 90.9%. The vision was improved in 76.1% of patients with visual impairments. Preoperatively, various endocrinological deficiencies were revealed in 73.7% of 76 patients with hypothalamus-pituitary lesions, and the hyposomatotropism was most common. Endocrinological status was improved only in 10. Aseptic or bacterial meningitis (7.3%) was the most common surgical complication, and the cerebrospinal fluid leakage rate was 2.4%. CONCLUSIONS EES provides favorable neurological outcomes with acceptable risk for children with brain tumors. The high incidence of endocrinological deficits in cases with hypothalamus-pituitary lesions emphasizes the importance of judicious pre- and postoperative evaluation.

Abstract
Abstract
Background
There is some debate on whether or not there is a gender difference is present between current smoking and cardiovascular disease.
Purpose
We decide to evaluate the impact of sex difference on the 2-year clinical outcomes in Korean acute myocardial infarction (AMI) patients who currently smoke and who underwent percutaneous coronary intervention (PCI) with drug-eluting stents (DES).
Methods
The data of this study was obtained from the Korea Acute Myocardial Infarction (KAMIR) registry. More than fifty high-volume universites or community hospitals with facilities for primary PCI and onsite cardiac surgery participated in this KAMIR registry. A total of 12565 current smoker AMI patients were enrolled and divided into the male (n=11767, 93.6%) or female (n=798, 6.4%) group. The clinical endpoint was the occurrence of major adverse cardiac events (MACE) defined as all-cause death, recurrent myocardial infarction (re-MI), and total repeat revascularization.
Results
Before risk adjustment, the cumulative incidences of MACE (7.2% vs. 10.0%, hazard ratio [HR], 1.419; 95% confidence interval [CI], 1.125–1.790; P=0.003), all-cause death (HR, 1.988; 95% CI, 1.417–2.789; P<0.001), and re-MI (HR, 1.885; 95% CI, 1.154–3.078; P=0.011) were significantly higher in the female group compared with the male group. However, after adjustment the cumulative incidences of MACE (adjusted HR, 1.047; 95% CI, 0.756–1.450; P=0.782), all-cause death, re-MI, total repeat revascularization, TLR, TVR, and non-TVR were similar between the two groups.

Abstract
Abstract
Background
Incidence and outcomes of new-onset ventricular tachycardia (VT) after cardiac surgery are not fully evaluated.
Purpose
We retrospectively analyzed the occurrence of new-onset VTs after cardiac surgery, and their implications on short and long-term mortality.
Methods
Data of 11,004 adult patients who underwent cardiac surgery at our center from 2006 to 2016 were analyzed. VT was diagnosed when 3 or more consecutive wide QRS complexes (>100 bpm) were documented on ECG. The major study outcomes were in-hospital and 5-years overall mortality rates.
Results
During index hospitalization for cardiac surgery, clinical VTs were documented in 184 patients (1.7%), which included 74 sustained VTs (SusVT, ≥30 seconds) and 110 non-sustained VTs (NSVT). Those patients with SusVT and NSVT showed higher in-hospital mortality compared to those without VTs (31.1% vs. 24.5% vs. 2.0% for SusVT, NSVT, and no VT, respectively, P<0.001). During follow-up after discharge from index hospitalization, patients with SusVT showed higher 5-years mortality than those without VTs, while patients with NSVT did not showed significant differences (22.0% vs. 11.7% vs. 9.2%, P<0.001). In the subgroup of patients with sustained VT who were discharged from index hospitalization (n=51), those with recurrent VTs (>24 hours apart from initial episode) were at higher 5-years mortality rate compared to those without (40.7% vs. 15.8%, P=0.018).
Conclusion
Patients with SusVT and NSVT were at higher risk of in-hospital mortality, and patients with SusVT were associated with higher risk of long-term mortality. The mortality risk was even higher in those with recurrent episodes of VTs.

Abstract
Abstract
Background
Patients with atrial fibrillation (AF) who survive an intracranial haemorrhage (ICH) are at high risk of stroke, death, and recurrent haemorrhage. Effectiveness and safety of the nonvitamin K antagonist oral anticoagulant (NOAC) edoxaban in this patient population has not been reported.
Purpose
This snapshot analysis from the global ETNA-AF program compared 1-year outcomes in AF patients with and without history of ICH treated with edoxaban from Europe, Japan, and Korea/Taiwan.
Methods
Global ETNA-AF (EU: NCT02944019, Japan: UMINehz745.116117011, Korea/Taiwan: NCT02951039) is a multinational, multicentre, prospective, noninterventional program of AF patients receiving edoxaban in regular clinical care. Demographics, baseline characteristics, and outcomes at 1-year follow-up were reported for 19416 patients with and without a history of ICH.
Results
Of the 19416 patients, 297 had a history of ICH. At 1-year follow-up, incidences of International Society on Thrombosis and Haemostasis (ISTH) major bleeding (including ICH) and clinically relevant nonmajor bleeding (CRNMB) were generally low. The rate of ischaemic stroke was higher in patients with a history of ICH than in those without prior ICH.

Abstract
Abstract
Background
Radiofrequency catheter ablation (RFCA) for accessory pathways (APs) at the site of prior valve surgery remains challenging. We aimed to clarify the factors associated with successful RFCA for such APs.
Methods
Upon reviewing a RFCA registry and previous case reports, we included nine patients who underwent RFCA of APs at the site of prior valve surgery (total-VS group; age, 34.0 [24.5–45.0] years; men, 4/9) and 196 patients who underwent RFCA of APs with no history of valve surgery (no-VS group; age, 40.5 [23.0–54.0] years; men, 114/196). Electrophysiological features, procedural details, and outcomes were examined.
Results
AP exhibited decremental conduction in four of nine patients in the total-VS group. The number of RFCA attempts was significantly higher in the total-VS group than in the no-VS group (10.0 [4.5–14.5] vs 2.0 [1.0–3.0]; p<0.001). In four patients who underwent mitral valve surgery, successful RFCA was achieved using the transaortic approach, coronary sinus approach, or bipolar ablation. In three patients who underwent tricuspid valve surgery, successful RFCA was achieved using the above-prosthetics or trans-prosthetics approach. In two patients, RFCA failed. The trans-prosthetics approach and bipolar ablation technique were effective. The transaortic and coronary sinus approaches were occasionally effective. The transseptal approach was ineffective. Based on the success rate and accessibility, we suggest a stepwise approach to RFCA of APs at the site of prior mitral or tricuspid valve surgery (Figure).
Stepwise approach to AP at valve surgery
Conclusions
Successful RFCA of APs at the site of prior valve surgery can be achieved by detailed mapping of the areas both above and below the prosthetic valve, as well as by ensuring effective radiofrequency energy delivery using various catheter approaches and RFCA techniques.

Abstract
Abstract
Background
Gender difference in stroke risk by the presence of atrial fibrillation was not well evaluated.
Purpose
We hypothesized that the gender showed different impacts on future thromboembolic risk in patients with and without atrial fibrillation.
Methods
The study population comprised of 26,226 patients (mean 56.3 years old, 52.6% male) with (n=3147, 12.0%) or without (n=23079, 88.0%) atrial fibrillation who underwent cardiac evaluations consisted of electrocardiography, echocardiography, and holter monitoring in our center. The main study outcomes were thromboembolic events defined as composite of ischemic stroke and systemic embolism.
Results
During mean follow-up period of 2.8 years, thromboembolic event occurred in 610 patients (2.3%). In the overall population, the 3-year rate of thromboembolic event of female patients was lower than males (2.2% vs. 2.8%, P=0.011). However, when the population was divided according to the presence of AF, females showed higher rate of thromboembolic events in those with AF (6.7% vs 3.1%, P<0.001), whereas lower rate in those without AF (1.7% vs. 2.7%, P<0.001, P for interaction between gender and AF <0.001). After multivariable adjustment, female gender was at higher risk of future thromboembolic events in those with AF (HR 1.61, 95% CI 1.13–2.29, P<0.001), whereas at lower risk in those without AF (HR 0.75, 95% CI 0.62–0.91, P=0.003). The interaction between gender and AF was significant in those who had one or more components of CHA2DS2-VASc score other than gender (CHA2DS2-VA score ≥1, P for interaction = 0.001), but not in those without (P for interaction = 0.196)
Conclusion
Female gender demonstrated differential thromboembolic risk according to the presence of AF.

Abstract
Abstract
Background
Risk factors for the occurrence of embolic stroke (ES) after atrial fibrillation (AF) ablation have not been fully elucidated. Our aim was to assess incidence of ES during long-term follow-up following AF ablation and to identify predicting factors associated with post-ablation ES.
Methods
We enrolled patients who experienced ES after AF ablation and body mass index-matched controls from AF ablation registries. Epicardial adipose tissue (EAT) was assessed using multislice computed tomography prior to ablation.
Results
A total of 3,464 patients who underwent AF ablation were recruited. During a mean follow-up of 47.2 months, ES occurred in 47 patients (1.36%) with a mean CHA2DS2-VAS score of 2.15 and overall incidence of ES was 0.34 per 100 patients/year. Compared with control group (n=190), ES group had more higher prior thromboembolic event and AF recurrence rates, larger LA size, lower creatinine clearance rate (CCr), and greater total and periatrial EAT volumes although no differences in AF type, CHA2DS2-VASc score, ablation extent, and anti-thrombotics use were found. On multivariate regression analysis, a prior history of thromboembolism, CCr, and periatrial EAT volume were independently associated with ES occurrence after AF ablation.

Conclusions
Incidence of ES after AF ablation was lower than expected rate based on CHA2DS2-VASc score even though anticoagulants use was limited. Periatrial EAT volume, a prior thromboembolism event, and CCr were independent factors in predicting ES irrespective of AF recurrence and CHA2DS2-VASc score in patients who underwent AF ablation.

Abstract
Abstract
Background
Limited comparative data are available.
Purpose
We decided to compare 2-year major clinical outcomes between statin with ACEI and statin ARB therapy in patients with STEMI after PCI with drug-eluting stents (DES).
Methods
A total 11706 STEMI patients who underwent PCI with DES and who prescribed statin were enrolled and they were divided into two groups, the statin with ACEI group (n=8705) and the statin with ARB group (n=3001). The primary endpoint was the major adverse cardiac events (MACE) defined as all-cause death, recurrent myocardial infarction (re-MI), target lesion revascularization (TLR), target vessel revascularization (TVR), non-TVR. The secondary endpoints were the cumulative incidences of individual components of MACE and target vessel failure (TVF), a composite of death related to the target vessel, re-MI, or clinically driven TVR.
Results
Two PSM groups (2835 pairs, n=5670, C-statistic = 0.680) were generated. The relative risk of MACE was higher in the statin with ARB group compared to statin with ACEI groups after propensity score-matched (PSM) analysis (hazard ratio [HR]: 1.323, 95% confidence interval [CI]: 1.085–1.613, p=0.006). The relative risks of cardiac death (HR: 1.831, 95% CI: 1.199–2.740, p=0.005), total repeat revascularization (HR: 1.487, 95% CI: 1.133–1.950, p=0.004), and non-TVR (HR: 1.696, 95% CI: 1.122–2.564, p=0.012) were also higher in the statin with ARB group after PSM.
Outcomes Cumulative Events at 2-year (%) Hazard Ratio (95% CI) p value Statin + ACEI Statin + ARB Log-rank Propensity score matched Patients MACE 173 (6.5) 225 (8.5) 0.006 1.323 (1.085–1.613) 0.006 All-cause death 58 (2.2) 80 (3.0) 0.054 1.391 (0.992–1.950) 0.056 Cardiac death 35 (1.3) 63 (2.3) 0.004 1.831 (1.199–2.740) 0.005 Re-MI 39 (1.5) 44 (1.7) 0.548 1.141 (0.742–1.756) 0.548 Total repeat revascularization 88 (3.4) 128 (4.9) 0.004 1.487 (1.133–1.950) 0.004 TLR 26 (1.0) 40 (1.5) 0.075 1.561 (0.953–2.558) 0.077 TVR 53 (2.0) 71 (2.8) 0.086 1.364 (0.955–1.946) 0.088 Non-TVR 36 (1.4) 60 (2.3) 0.011 1.696 (1.122–2.564) 0.012 TVF 140 (5.3) 173 (6.6) 0.050 1.249 (1.000–1.561) 0.050
Conclusions
In this study, we suggest that the combination of statin with ACEI may be beneficial for reducing the cumulative incidences of MACE, total repeat revascularization rate, and non-TVR rather than the statin with ARB after PCI with DES in STEMI patients.

Abstract
Abstract
Background
Although European guideline recommends that statin should be given to all patients with acute myocardial infarction (AMI), irrespective of cholesterol concentration, limited studies were focused on the long-term effects of statin therapy between ST-segment elevation MI (STEMI) and non-ST-segment elevation MI (NSTEMI).
Purpose
The authors conducted the study to compare the relative beneficial role of statin on 2-year major clinical outcomes between STEMI and NSTEMI in patients who underwent successful PCI with DES.
Methods
Finally, a total of 26317 AMI patients who underwent stent implantation and who were prescribed the statin were enrolled and they were separated into two groups; the STEMI group (n=15002) and the NSTEMI group (n=11315). The clinical endpoint was the occurrence of major adverse cardiac events (MACE) defined as all-cause death, recurrent myocardial infarction (re-MI), total coronary revascularization (target lesion revascularization [TLR], target vessel revascularization [TVR], non-TVR) during 2-year follow-up period.
Results
After propensity score-matched (PSM) analysis, two PSM groups (7746 pairs, n=15492, C-statistic = 0.766) were generated. In the total study population, the cumulative incidences of MACE, all-cause death, and cardiac death were significantly higher in the NSTEMI group. However, after PSM, the cumulative incidence of all-cause death (Hazard ratio, 1.386; 95% CI, 1.133–1.696; p=0.002) was significantly higher in the NSTEMI group. The cumulative incidences of MACE, cardiac death, re-MI, total revascularization, TLR, TVR, and non-TVR were similar between the two groups (Table 1).
Outcomes Cumulative Events at 2-year (%) Hazard Ratio (95% CI) p value STEMI NSTEMI Log-rank Propensity score matched patients MACE 532 (7.2) 584 (8.1) 0.092 1.106 (0.984–1.244) 0.092 All-cause death 163 (2.2) 224 (3.1) 0.001 1.386 (1.133–1.696) 0.002 Cardiac death 121 (1.5) 148 (2.0) 0.088 1.232 (0.969–1.566) 0.089 Re-MI 117 (1.6) 107 (1.5) 0.545 0.922 (0.710–1.199) 0.545 Total revascularization 291 (4.1) 307 (4.4) 0.422 1.068 (0.910–1.254) 0.423 TLR 92 (1.3) 89 (1.2) 0.880 0.978 (0.731–1.309) 0.880 TVR 173 (2.4) 184 (2.6) 0.478 1.078 (0.876–1.327) 0.478 Non-TVR 123 (1.7) 130 (1.9) 0.593 1.070 (0.836–1.369) 0.539
Conclusion
The mortality reduction capability of statin was more prominent in the STEMI group compared with the NSTEMI group.

Abstract
Abstract
Background
There are limited comparative data concerning long-term major clinical outcomes between male and female in dyslipidemic AMI patients after PCI with new-generation DES.
Purpose
We thought to investigate the impact of gender difference on the 2-year clinical outcomes.
Methods
Finally, a total of 2403 eligible dyslipidemic AMI patients who underwent PCI with new-generation DES were enrolled and they were separated into two groups; the male group (n=1800) and the female group (n=603). The primary endpoint was major adverse cardiac events (MACE) defined as all-cause death, recurrent myocardial infarction (re-MI), target lesion revascularization (TLR), and target vessel revascularization (TVR). The secondary endpoints were the incidence of the individual components of MACE and target vessel failure (TVF), a composite of death related to the target vessel, re-MI, or clinically driven TVR
Results
Two propensity score-matched (PSM) groups (422 pairs, n=844, C-statistic = 0.850) were generated. In the total study population, the cumulative incidences of MACE, all-cause death, re-MI, and TVF were significantly higher in the female group compared with the male group. However, after propensity score-matched (PSM) analysis, the cumulative incidences of MACE (HR, 0.971; 95% CI, 0.628–1.501; p=0.895), all-cause death (HR, 1.061; 95% CI, 0.536–2.100; p=0.865), re-MI (HR, 1.212; 95% CI, 0.433–2.907; p=0.813), and TVF (HR, 0.764; 95% CI, 0.474–1.229; p=0.267) were similar between the two groups. In addition, the cumulative incidences of cardiac death, TLR, TVR were not significantly different between the two groups (Table 1).
Outcomes Cumulative Events at 2-year (%) Hazard Ratio (95% CI) p value Male Female Log-rank Propensity score matched patients MACE 41 (10.4) 40 (10.3) 0.895 0.971 (0.628–1.501) 0.895 All-cause death 16 (4.0) 17 (4.2) 0.865 1.061 (0.536–2.100) 0.865 Cardiac death 13 (3.3) 9 (2.2) 0.391 0.691 (0.295–1.616) 0.393 Re-MI 8 (2.0) 9 (2.4) 0.813 1.212 (0.433–2.907) 0.813 TLR 7 (1.8) 6 (1.6) 0.781 0.857 (0.298–2.550) 0.781 TVR 16 (4.3) 10 (2.7) 0.236 0.623 (0.283–1.373) 0.241 TVF 39 (10.2) 30 (7.8) 0.265 0.764 (0.474–1.229) 0.267
Conclusion
The gender difference was not apparent in these dyslipidemic South Korean AMI patients who underwent PCI with new-generation DES during 2-year follow-up period.

Abstract
BACKGROUND Invasive nonfunctioning pituitary adenomas (NFPAs) remain challenging due to their high complication rate and poor prognosis. We aimed to identify the distinctive molecular signatures of invasive NFPAs, compared with noninvasive NFPAs, using gene expression profiling by RNA sequencing. METHODS We obtained frozen fresh tissue samples from 14 patients with NFPAs who underwent primary transsphenoidal surgery. Three non-invasive and 11 invasive NFPAs were used for RNA sequencing. The bioinformatics analysis included differential gene expression, gene ontology analysis, and pathway analysis. RESULTS A total of 700 genes were differentially expressed (59 up-regulated and 641 down-regulated genes) between invasive and non-invasive NFPAs (false discovery rate <0.1, and |fold change| ≥2). Using the down-regulated genes in invasive NFPAs, gene ontology enrichment analyses and pathway analyses demonstrated that the local immune response was attenuated and that transforming growth factor-β (TGF-β) RII-initiated TGF-β signaling was down-regulated in invasive NFPAs. The overexpression of claudin-9 (CLDN9) and the down-regulation of insulin-like growth factor-binding protein 5 (IGFBP5), death-associated protein kinase 1 (DAPK1), and tissue inhibitor of metalloproteinase-3 (TIMP3) may be related with invasiveness in NFPAs. CONCLUSION Invasive NFPAs harbor different gene expression profiles relative to noninvasive NFPAs. In particular, local suppression of the immune response and TGF-β signaling can make PAs prone to invasiveness.

Abstract
A direct and complete measurement of isotopic fission-fragment yields of ^{239}U has been performed for the first time. The ^{239}U fissioning system was produced with an average excitation energy of 8.3 MeV in one-neutron transfer reactions between a ^{238}U beam and a ^{9}Be target at Coulomb barrier energies. The fission fragments were detected and isotopically identified using the VAMOS++ spectrometer at the GANIL facility. The measurement allows us to directly evaluate the fission models at excitation energies of fast neutrons, which are relevant for next-generation nuclear reactors. The present data, in agreement with model calculations, do not support the recently reported anomaly in the fission-fragment yields of ^{239}U, and they confirm the persistence of spherical shell effects in the Sn region at excitation energies exceeding the fission barrier by a few mega-electron volts.

Abstract
Objective The number of high-risk pregnancies is increasing in tertiary medical centers. Therefore, we investigated perioperative outcomes based on risk factors to ascertain proper maternal and neonatal management. Methods We reviewed the medical records of patients receiving cesarean sections over an 8-year period. Clinical parameters for anesthesia and the neonatal outcome were compared among high-risk groups after subdivision by the number of clinical risk factors. The groups were as follows: group A (one risk factor), group B (two risk factors), and group C (three or more risk factors). Results Patient age, estimated blood loss (EBL), and volume of transfused red blood cell (RBC) were higher in group B than group A. Birth weight, 1- and 5-minute Apgar scores, and gestational age were lower while the frequency of neonatal intensive care unit (NICU) admission was higher in group B than group A. Group C patients were significantly older than group A or B patients. Birth weight, 1- and 5-minute Apgar scores and gestational age were significantly lower while frequency of NICU admission was higher in group C than group A and B. Conclusion The number of maternal risk factors was positively associated with adverse outcomes in the neonates.
