[1] The lowermost mantle beneath Central America has anisotropic seismic velocity structure manifested in shear wave splitting of signals from South American earthquakes recorded at North American broadband recording stations. Prior studies of deep mantle anisotropy in this region have characterized the structure as having vertical transverse isotropy (VTI), which is sufficient to explain a gen...

Background: Understanding symptomatology and accuracy of clinical case definitions for community COVID-19 cases is important Test, Trace Isolate (TTI) future targeting early antiviral treatment. Methods: Community cohort participants prospectively recorded daily symptoms swab results (mainly undertaken through the UK TTI system). ...

BACKGROUND The McGrath videolaryngoscope (VL) provides excellent laryngoscopic views, but directing an endotracheal tube can be difficult, and thus the routine use of a stylet is recommended. The goal of this study is to determine the appropriate angle (60° vs 90°) of the stylet when using the McGrath VL by comparing the time to intubation (TTI). METHODS One hundred and forty patients aged 19...

Background. AECOPD is a life threatening condition for patients with chronic obstructive pulmonary disease (COPD) and lack of specific biomarker hinders effective management. Sputum, blood, breath and urinary biomarkers have all been investigated. We measured maximum respiratory pressure post exacerbation once the patient was compliant with the test and after 6 weeks, to assess any correlations...

So ERA-5 reanalysis can be used obtain temperatures predicting events. The indices this are CAPE, KI TTI. located with testing 00UTC – 24UTC Supported form sea su...

Abstract Aims Cryoballoon (CB) pulmonary vein isolation (PVI) is an accepted ablation strategy for rhythm control in atrial fibrillation (AF). We describe efficacy and safety a high volume centre with long experience the use of second-generation CB (CB2). Methods results Consecutive paroxysmal AF (PAF) or persistent (persAF) patients undergoing CB2-PVI were enrolled. Procedural data, efficacy, ...

OBJECTIVES It remains to be determined whether the TVI-4000 Trachway video intubating (TVI) stylet (Markstein Sichtec Medical Corp, Taichung, Taiwan), an airway device for novices, improves airway management practice by experienced anesthesiologists. The aim of this study was to evaluate the feasibility of using the TVI stylet in difficult tracheal intubation situations compared with that of us...

We tested the hypothesis that static contraction causes greater reflex cardiovascular responses than dynamic contraction at equivalent workloads [i.e., same tension-time index (TTI), holding either contraction time or peak tension constant] in chloralose-anesthetized cats. When time was held constant and tension was allowed to vary, dynamic contraction of the hindlimb muscles evoked greater inc...

QUESTION Question: What is the predictive validity of the revised Conners' Teacher Rating Scale (CTRS-R) for identifying children with attention defi cit hyperactivity disorder (ADHD) in a clinical sample compared with the Telephone Teacher Interview (TTI-IV)? Patients: 1038 children aged 6–12 years referred for assessment of attention, learning and behavioural problems to a paediatric clinic (...

Time-temperature index (TTI) modeling is used to establish a simple theoretical thermal maturity for Paleozoic strata in central Kansas. These thermal maturation calculations are based on estimates of likely geothermal gradients and best knowledge of the tectonic history of the region, as derived from stratigraphic thicknesses and estimates of erosion at unconformities. Major uncertainties in t...
