We assessed the prognostic ability of several inflammation-based scores and compared their long-term outcomes in patients with peripheral artery disease (PAD) following endovascular treatment (EVT). ...We included 278 patients with PAD who underwent EVT and classified them according to their inflammation-based scores (Glasgow prognostic score GPS, modified GPS mGPS, platelet to lymphocyte ratio PLR, prognostic index PI, and prognostic nutritional index PNI). Major adverse cardiovascular events (MACE) at 5 years were examined, and C-statistics in each measure were calculated to compare their MACE predictive ability. During the follow-up period, 96 patients experienced MACE. Kaplan–Meier analysis showed that higher scores of all measures were associated with a higher MACE incidence. Multivariate Cox proportional hazard analysis showed that GPS 2, mGPS 2, PLR 1, and PNI 1, compared with GPS 0, mGPS 0, PLR 0, and PNI 0, were associated with an increased risk of MACE. C-statistics for MACE for PNI (.683) were greater than those for GPS (.635, P = .021), mGPS (.580, P = .019), PLR (.604, P = .024), and PI (.553, P < .001). PNI is associated with MACE risk and has a better prognosis-predicting ability than other inflammation-scoring models for patients with PAD following EVT.
Atomic halogen elimination from halogen-related compounds plays a vital role in the depletion of the ozone layer and is well investigated. However, the probabilities for elimination of molecular ...halogens and hydrogen halides are rarely scrutinised. We develop distinct method for the investigation of each kind of fragment. Velocity-mapping ion-imaging was employed to study the atomic halogen elimination from alkyl halides and aryl halides, focusing on the fractions of the translational energy release, the quantum yields of the atomic fragments, transition probability for curve crossing, competitive halogen-related bond fission, and anisotropy parameters to understand their dynamical complexity. Cavity ring-down absorption spectroscopy was implemented to investigate the molecular halogen fragments dissociated from the aliphatic halides and acyl halides for their optical spectra, vibrational branches, quantum yields, and the dissociation mechanisms. Time-resolved Fourier transform infrared emission spectroscopy was employed to confine the primary products of hydrogen halide elimination from acyl halides in the presence of Ar gas. It is, for the first time, to overview these existing small halogen-related fragments eliminated from halogen-containing compounds. The detailed characterisation of these fragments should unveil complicated halogen-related dissociation mechanisms which may supplement the current knowledge and help with the photochemical assessment of halogen-related environmental issue.
This study aimed to examine the effects of flooding due to Typhoon Hagibis on the incidence of cardiovascular/cerebrovascular events in Nagano City.
The SAVE trial retrospectively enrolled 2426 ...patients hospitalized for cardiovascular/cerebrovascular disease in 5 hospitals in Nagano City from October 1 to December 31 in 2017 and 2018 (pre-disaster period) and in 2019 (post-disaster period). From these, 280 patients who were hospitalized in a district flooded in 2019 were recruited for the same period (October 12 to December 31) over the 3 years. The baseline characteristics of and the incidence of cardiovascular/cerebrovascular disease in cases from the flooded district in 2019 were compared with those of cases in the flooded district in 2017 and 2018.
The total number of patients with acute myocardial infarction did not differ significantly between the post- and pre-disaster periods. The incidence of unstable angina pectoris was significantly higher in 2019 (n = 4, 5.1%) than in 2017 and 2018 (n = 0, 0.0%) (
= 0.001).
This study did not prove the impact of flood due to a typhoon on the incidence of cardiovascular/cerebrovascular events.
Abstract
Pattern analysis of the impact‐parameter dependent trajectory for the H + H
2
exchange reaction was performed at temperatures
T
= 3 and 300 K by employing the quasi‐classical trajectory ...calculation on a London‐Eyring‐Polanyi‐Sato surface. We find that (a) 0.66 fraction of reactive trajectories throughout
b
= 0.0 ~ 5.0 Å at
T
= 3 K, while only 0.33 at
T
= 300 K only for
b
= 0.0 ~ 1.5 Å and decreases soon to zero for
b
= 2.5 ~ 5.0 Å. (b) Ninety eight percent of the trajectories showed direct collision pattern at
T
= 300 K, while at
T
= 3 K, 72% for direct collision trajectories and 28% showed the intermediate H + H
2
complex formation pattern. These results suggest that nonzero impact‐parameter trajectories play a role at
T
= 3 K to enhance reactivity due to long‐range attraction forces. Trajectory pattern analysis reveals a characteristic propensity rule between the amplitude of the time‐dependent interaction potential and the trajectory reactivity, thus we can judge if a trajectory is reactive or nonreactive. The analysis also proposes a roaming‐like libration motion at
T
= 3 K like in the interstellar clouds.
Chemical reactions of methyl chloride (CH3Cl) on a clean Si(001) surface at ∼300 K are studied by means of scanning tunneling microscopy (STM) under ultra-high-vacuum conditions. The features ...appearing in the STM images are identified with the possible products of dissociated CH3 and Cl, and their distribution is also evaluated as well as the development of their distribution with increasing CH3Cl doses. The amount of Cl atoms found on the surface is approximately twice as large as that of the CH3 molecules. This leads to the conclusion that dissociative adsorption of CH3Cl on Si occurs in different processes: CH3Cl(precursor) → CH3(ad) + Cl(ad) and CH3Cl(precursor) → CH3(gas) + Cl(ad).
▶ We report results of our detailed studies on the initial oxidation process of TiNi. ▶ We elucidated the oxidation processes using high-resolution XPS measurements. ▶ We succeeded in fabricating ...thick Ni-free TiO2 layer on TiNi using molecular beams.
We report results of our detailed studies on the initial oxidation process of TiNi with a 2eV hyperthermal oxygen molecular beam (HOMB) and thermal O2 in the backfilling. The oxidation processes are monitored by X-ray photoemission spectroscopy (XPS) measurements in conjunction with synchrotron radiation (SR). In the early stage of oxidation, the precursor mediated dissociative adsorption is the dominant reaction mechanism. In the oxide formation process at higher O coverage, HOMB has the advantage in the dissociation process of O2 molecule and can grow TiO2 layers with the underlying TiOx-rich and/or Ni-rich layers. We succeeded in fabricating thick Ni-free TiO2 layer, possibly blue colored rutile TiO2, combining HOMB and surface annealing.
