Abstract Background Patients with major depressive disorder (MDD) having active suicidal ideation intent require immediate treatment. Methods This double-blind study (ASPIRE II) randomized adults (aged 18–64 years) MDD to esketamine 84 mg or placebo nasal spray twice weekly for 4 weeks, given comprehensive standard of care (hospitalization ≥5 days and newly initiated optimized oral antidepressant[s]). Change from baseline 24 hours post-first dose in Montgomery-Asberg Depression Rating Scale...

Asphalt pavement, widely utilized in transportation infrastructure due to its favourable properties, faces significant degradation from chloride salt erosion coastal areas and winter deicing regions. In this study, two commonly used asphalt binders, 70# base SBS (Styrene–Butadiene–Styrene)-modified asphalt, were study the effect on pavement by immersing materials laboratory-prepared solutions. The conventional properties adhesion of assessed using penetration, softening point, ductility,...

The authors compared baseline demographic characteristics, clinical features, and grief-related thoughts, feelings, behaviors of individuals bereaved by suicide, accident/homicide natural causes participating in a complicated grief (CG) treatment trial. Severity CG depression current diagnosis did not vary loss type. After adjusting for time since death relationship to the deceased, those with after suicide had highest rates lifetime depression, preloss passive suicidal ideation,...

Abstract Purpose/Background Numerous health authority approvals of esketamine nasal spray, combined with oral antidepressant, to treat depressive symptoms in adults major disorder and acute suicidal ideation or behavior were based on 2 identically designed, double-blind, phase 3 studies. Methods/Procedures Across both ASPIRE studies (NCT03039192, NCT03097133), patients (N = 456) randomized 84 mg placebo spray twice weekly for 4 weeks plus comprehensive standard care, including...

Asphalt mastic plays an important role in asphalt mixtures for pavement engineering. Understanding the asphalt-filler interaction behavior is essential to improve performance of mastics. The objective this paper was evaluate ability based on macro-rheological measurements and investigate mechanism associated with microstructural characteristics First, characterized using features mastics dynamic shear rheometer (DSR) tests. Second, physico-chemical between filler qualitatively evaluated a...

The interfacial bonding capacity between cement emulsified asphalt composite binder (CEACB) and reclaimed pavement (RAP) plays a critical role in improving the performance of cold recycled emulsion mixtures (CRAEMs). This study aims to investigate formation development CEACB RAP. First, dynamic wettability spreading behaviors on RAP surfaces were explored according surface free energy theory. Second, digital image processing (DIP) technology was employed recognize failure patterns. Lastly,...

Abstract Purpose To assess the effect of esketamine nasal spray on patient-reported outcomes (PROs) in patients with major depressive disorder having active suicidal ideation intent (MDSI). Methods Patient-level data from two phase 3 studies (ASPIRE I; ASPIRE II) + standard care (SOC) (aged 18–64 years) MDSI, were pooled. PROs evaluated baseline through end double-blind treatment (day 25). Outcome assessments included: Beck Hopelessness Scale (BHS), Quality Life (QoL) Depression (QLDS),...
