Introduction The risk of rebleeding is highest during the initial hours after aneurysmal subarachnoid haemorrhage (aSAH), but the aneurysm is not occluded in all patients immediately after admission. Our aim was to determine the proportion of aSAH patients with poor outcome from early in-hospital rebleeding that can be prevented by three emergency aneurysm occlusion regimes. Patients and methods From our prospectively collected database, we retrieved from all aSAH patients admitted between July 2007 and July 2017 data on clinical condition on admission, time of rebleeding, and outcome at 3 months. Results Of 1391 consecutive aSAH patients, 923 were in good clinical condition and had an aneurysm on initial imaging that was amenable for treatment. Poor outcome from rebleeding could have been avoided by treatment <4 h during day time shifts in 4 (0.4% [95% CI: 0.2-1.1]) patients (number needed to treat [NNT]: 250), by treatment and <1 h during daytime shift in 9 (1.0% [95% CI: 0.5-1.8]; NNT: 111), and treatment <1 h at 24/7 basis in 16 (1.7% [95% CI: 1.1-2.8%]; NNT: 59). Discussion Emergency aneurysm occlusion can reduce poor outcome due to rebleeding, but only in small proportions of patients. Whether such strategies lead to improved outcome for all patients and are cost-effective is highly uncertain. Conclusion We do not recommend instalment of a treatment regimen where occlusion of ruptured aneurysm is performed within 1 h on a 24/7 basis.

NaTi3O6(OH)center dot 2H(2)O, also known as "sodium nonatitanate" (NNT) can undergo reversible sodium (de)insertion at low potentials centered around 0.3 V. The low average insertion potential and high theoretical capacity (similar to 200 mA h g(-1)based on site considerations) suggest that it can be a promising high energy density anode material for sodium-ion batteries. However, its low practical capacity, poor capacity retention, and low initial coulombic efficiency require further material and electrode optimization. Herein, the optimization of the material properties of NNT as well as electrode engineering were used to improve these aspects of the electrochemical performance. Characterization tools including pair distribution function analysis, synchrotron X-ray diffraction, and soft and hard X-ray absorption spectroscopy were utilized to probe details of the crystal and electronic structure. Upon drying, rearrangement of the sodium ions in the interlayer space and formation of O-Na-O bridges occur. Hard and soft X-ray absorption spectroscopy show that charge transfer occurs upon discharge of the material in sodium half-cells, consistent with a reversible reductive intercalation mechanism. The best-performing electrodes were dehydrated at 500 degrees C, and the highest initial capacities of about 200 mA h g(-1)were obtained when a CMC binder was used and NNT was carbon-coated. Wrapping NNT with only 1 wt% graphene also resulted in improved performance.
