Patient-reported efficacy of adjunctive brexpiprazole in major depressive disorder in a phase 4, open-label, interventional study.

Objectives: In ENGAGE, patients with major depressive disorder (MDD) demonstrated improvements in patient-reported depression and life engagement while taking adjunctive brexpiprazole. This analysis aimed to further characterize patient perspectives on the effects of adjunctive brexpiprazole, using patient diary data from ENGAGE, and describe development of a 'word of the day' activity.

Methods: Prior to ENGAGE, word lists describing a 'good,' 'average,' and 'bad' day with depression were generated from semi-structured interviews with patients with MDD.

A new Mongolian tyrannosauroid and the evolution of Eutyrannosauria.

Eutyrannosaurians were large predatory dinosaurs that dominated Asian and North American terrestrial faunas in latest Cretaceous times. These apex predators arose from smaller-bodied tyrannosauroids during the 'middle' Cretaceous that are poorly known owing to the paucity of fossil material. Here we report on a new tyrannosauroid, Khankhuuluu mongoliensis gen.

Ontogenetic Changes in Endocranial Anatomy in Gorgosaurus libratus (Theropoda: Tyrannosauridae) Provide Insight Into the Evolution of the Tyrannosauroid Endocranium.

Over the past two decades, increased accessibility to computed tomography (CT) scanners has greatly facilitated documentation of the endocranium in numerous extinct theropod taxa. However, most of these studies have focused on the morphology of mature individuals, thus changes or variation through ontogeny of the endocranium in theropods remains largely unknown. The current study sheds light on the endocranial anatomy of the eutyrannosaurian tyrannosauroid, Gorgosaurus libratus, in both an ontogenetic and evolutionary context.

Adjunctive Brexpiprazole for Patient Life Engagement in Major Depressive Disorder: A Canadian, Phase 4, Open-Label, Interventional Study: Brexpiprazole d'appoint pour l'engagement dans la vie des patients souffrant de trouble dépressif majeur: une étude interventionnelle canadienne ouverte de phase 4.

Objectives: To characterize the effects of adjunctive brexpiprazole on patient life engagement and depressive symptoms in patients with major depressive disorder (MDD) using patient-reported outcomes.

Methods: An 8-week, Phase 4, open-label, interventional study was conducted at 15 Canadian trial sites between April 2021 and May 2022. Adult outpatients with MDD (at least moderately severe) and inadequate response to 1-2 antidepressants continued their current antidepressant and received oral adjunctive brexpiprazole 0.

Effects of Adjunctive Brexpiprazole on Individual Depressive Symptoms and Functioning in Patients With Major Depressive Disorder and Anxious Distress: Post Hoc Analysis of Three Placebo-Controlled Studies.

Purpose/background: Anxiety symptoms in major depressive disorder (MDD) are frequent, and they decrease response to antidepressant treatment (ADT), and affect patient functioning. This post hoc analysis examined the efficacy of adjunctive brexpiprazole on individual depressive symptoms and functioning in patients with MDD with anxious distress.

Methods/procedures: Data were included from three 6-week, randomized, double-blind, placebo-controlled studies of adjunctive brexpiprazole in patients with MDD and inadequate response to ADTs (ClinicalTrials.

Exceptionally preserved stomach contents of a young tyrannosaurid reveal an ontogenetic dietary shift in an iconic extinct predator.

Tyrannosaurids were large carnivorous dinosaurs that underwent major changes in skull robusticity and body proportions as they grew, suggesting that they occupied different ecological niches during their life span. Although adults commonly fed on dinosaurian megaherbivores, the diet of juvenile tyrannosaurids is largely unknown. Here, we describe a remarkable specimen of a juvenile that preserves the articulated hindlimbs of two yearling caenagnathid dinosaurs inside its abdominal cavity.

Improvement of functioning in patients with schizophrenia: real-world effectiveness of aripiprazole once-monthly (REACT study).

Background: Functional impairment affects many patients with schizophrenia. Treatment with the long-acting injectable antipsychotic aripiprazole once-monthly (AOM) may help improve functioning.

Objectives: To explore changes in functioning in patients with schizophrenia who received AOM treatment in observational studies.

Effects of adjunctive brexpiprazole on patient life engagement in major depressive disorder: Post hoc analysis of Inventory of Depressive Symptomatology Self-Report data.

Background: Patient-reported outcomes can capture domains that are meaningful to patients, such as life engagement in major depressive disorder (MDD), which reflects life fulfillment, well-being, and participation in valued and meaningful activities. This analysis investigated the effects of brexpiprazole adjunct to antidepressant treatment (ADT) on patient life engagement over the short and long term, using the 10-item Inventory of Depressive Symptomatology Self-Report (IDS-SR) Life Engagement subscale.

Methods: Short-term data were pooled from three 6-week, randomized, double-blind studies of ADT + brexpiprazole 2-3 mg/day versus ADT + placebo in adult outpatients with MDD (DSM-IV-TR criteria) and inadequate response to ADTs.

Evidence for heterothermic endothermy and reptile-like eggshell mineralization in , a non-avian maniraptoran theropod.

The dinosaur-bird transition involved several anatomical, biomechanical, and physiological modifications of the theropod bauplan. Non-avian maniraptoran theropods, such as , are key to better understand changes in thermophysiology and reproduction occurring during this transition. Here, we applied dual clumped isotope (Δ and Δ) thermometry, a technique that resolves mineralization temperature and other nonthermal information recorded in carbonates, to eggshells from , modern reptiles, and modern birds.

BPRS domains, items and subgroups analyses, and CGI-I ratings in pooled data from non-interventional studies of aripiprazole once-monthly in schizophrenia (REACT study).

Background: Patients with schizophrenia may benefit from treatment with long-acting injectable (LAI) formulations of antipsychotics. Aripiprazole once-monthly (AOM) is an LAI that was tested in two non-interventional studies in Germany and Canada.

Methods: Here, we report on analyses of pooled data from the two non-interventional studies.

Treatment with aripiprazole once-monthly injectable formulation is effective in improving symptoms and global functioning in schizophrenia with and without comorbid substance use - a post hoc analysis of the ReLiAM study.

Background: ReLiAM, Real-Life Assessment of Abilify Maintena, was the first reported long-term prospective non-interventional study for patients with schizophrenia treated with aripiprazole once-monthly injectable formulation (AOM) under real-life conditions. ReLiAM's primary aim was to evaluate the evolution of global functional status in patients treated with AOM for 12 months in Canada.

Methods: The objective of this post hoc analysis of the ReLiAM study is to investigate the treatment effects of real-life use of AOM over a 1-year period in the subgroup of patients with reported substance use compared with patients without substance use.

Exploring life engagement from the perspective of patients with major depressive disorder: a study using patient interviews.

Background: Patient-reported outcomes can measure health aspects that are meaningful to patients, such as 'life engagement' in major depressive disorder (MDD). Expert psychiatrists recently identified ten items from the Inventory of Depressive Symptomatology Self-Report (IDS-SR) that can be used to measure patient life engagement. This study aimed to explore the concept of patient life engagement and provide support for the IDS-SR Life Engagement subscale from the patient perspective.

Efficacy of adjunctive brexpiprazole on symptom clusters of major depressive disorder: A post hoc analysis of four clinical studies.

Background: Major depressive disorder (MDD) is a clinically heterogenous condition and its treatment should be individualized according to the presence of particular symptom clusters. The aim of this pooled analysis was to investigate the effects of adjunctive brexpiprazole on different symptom clusters in MDD.

Methods: Data were included from four similarly designed, short-term, randomized, double-blind, placebo-controlled studies of adjunctive brexpiprazole in adults with MDD and inadequate response to 2-4 antidepressant treatments (ADTs), including 1 administered by investigators.

Real-world effectiveness of aripiprazole once-monthly REACT study: Pooled analysis of two noninterventional studies.

Background: Noninterventional naturalistic studies are an important complement to randomized controlled trials. Aripiprazole once-monthly (AOM) is an atypical antipsychotic in a long-acting injectable formulation.

Methods: A pooled analysis of two noninterventional studies was undertaken to validate previous results on AOM effectiveness and safety in a larger population and improve statistical power for preplanned subgroup analyses.

"Dragons" on the landscape: Modeling the abundance of large carnivorous dinosaurs of the Upper Jurassic Morrison Formation (USA) and the Upper Cretaceous Dinosaur Park Formation (Canada).

Counts of the number of skeletal specimens of "adult" megaherbivores and large theropods from the Morrison and Dinosaur Park formations-if not biased by taphonomic artifacts-suggest that the big meat-eaters were more abundant, relative to the number of big plant-eaters, than one would expect on the basis of the relative abundance of large carnivores and herbivores in modern mammalian faunas. Models of megaherbivore population density (number of individuals per square kilometer) that attempt to take into account ecosystem productivity, the size structure of megaherbivore populations, and individual megaherbivore energy requirements, when combined with values of the large theropod/megaherbivore abundance ratio, suggest that large theropods may have been more abundant on the landscape than estimates extrapolated from the population density versus body mass relationship of mammalian carnivores. Models of the meat production of megaherbivore populations and the meat requirements of "adult" large theropods suggest that herbivore productivity would have been insufficient to support the associated number of individuals of "adult" large theropods, unless the herbivore production/biomass ratio was substantially higher, and/or the large theropod meat requirement markedly lower, than expectations based on modern mammals.

Effects of Brexpiprazole on Functioning in Patients With Schizophrenia: Post Hoc Analysis of Short- and Long-Term Studies.

To evaluate the short- and long-term effects of brexpiprazole on patient functioning in schizophrenia. Data were included from three 6-week, randomized, double-blind, placebo-controlled studies (hospitalized patients); a 52-week, randomized, double-blind, placebo-controlled maintenance treatment study (terminated early by the study sponsor based on the positive result of an interim analysis); and two 52-week, open-label extension studies-all in patients with schizophrenia ( criteria) and conducted from July 2011-February 2016. Patients allocated to oral brexpiprazole received 2-4 mg/d (short-term studies) or 1-4 mg/d (long-term studies).

Reassessment of a juvenile Daspletosaurus from the Late Cretaceous of Alberta, Canada with implications for the identification of immature tyrannosaurids.

Daspletosaurus is a large tyrannosaurine found in upper Campanian deposits of Alberta and Montana. Although several large subadult and adult individuals of this taxon are known, only one juvenile individual, TMP 1994.143.

Nest substrate reflects incubation style in extant archosaurs with implications for dinosaur nesting habits.

Dinosaurs thrived and reproduced in various regions worldwide, including the Arctic. In order to understand their nesting in diverse or extreme environments, the relationships between nests, nesting environments, and incubation methods in extant archosaurs were investigated. Statistical analyses reveal that species of extant covered nesters (i.

Accuracy of mandibular force profiles for bite force estimation and feeding behavior reconstruction in extant and extinct carnivorans.

Mandibular force profiles apply the principles of beam theory to identify mandibular biomechanical properties that reflect the bite force and feeding strategies of extant and extinct predators. While this method uses the external dimensions of the mandibular corpus to determine its biomechanical properties, more accurate results could potentially be obtained by quantifying its internal cortical bone distribution. To test this possibility, mandibular force profiles were calculated using both external mandibular dimensions ('solid mandible model') and quantification of internal bone distribution of the mandibular corpus obtained from computed tomography scans ('hollow mandible model') for five carnivorans (Canis lupus, Crocuta crocuta, Panthera leo, Neofelis nebulosa and the extinct Canis dirus).

Eggshell Porosity Provides Insight on Evolution of Nesting in Dinosaurs.

Knowledge about the types of nests built by dinosaurs can provide insight into the evolution of nesting and reproductive behaviors among archosaurs. However, the low preservation potential of their nesting materials and nesting structures means that most information can only be gleaned indirectly through comparison with extant archosaurs. Two general nest types are recognized among living archosaurs: 1) covered nests, in which eggs are incubated while fully covered by nesting material (as in crocodylians and megapodes), and 2) open nests, in which eggs are exposed in the nest and brooded (as in most birds).

A specimen of Rhamphorhynchus with soft tissue preservation, stomach contents and a putative coprolite.

Despite being known for nearly two centuries, new specimens of the derived non-pterodactyloid pterosaur Rhamphorhynchus continue to be discovered and reveal new information about their anatomy and palaeobiology. Here we describe a specimen held in the collections of the Royal Tyrrell Museum of Palaeontology, Alberta, Canada that shows both preservation and impressions of soft tissues, and also preserves material interpreted as stomach contents of vertebrate remains and, uniquely, a putative coprolite. The specimen also preserves additional evidence for fibers in the uropatagium.

The range of bioinclusions and pseudoinclusions preserved in a new Turonian (~90 ma) amber occurrence from Southern Australia.

A new Turonian amber occurrence, representing the oldest in situ amber locality in Australia and the southern-most locality in Gondwana, has recently been discovered in the Otway Basin of Victoria. The amber was collected from petroleum cores and many pieces contain a range of inclusions that can provide information on the depositional history of the resin. To date, one species of fern spore (Cyathidites minor) and one species of lycophyte spore (Kraeuselisporites sp?) have been conclusively identified in the amber, along with filamentous microorganisms and degraded plant matter.

The effect of ziprasidone on metabolic syndrome risk factors in subjects with schizophrenia: a 1 year, open-label, prospective study.

Objective: Metabolic syndrome (MetS) is prevalent in subjects with schizophrenia-related psychotic disorders and contributes to increased rates of premature death due to cardiovascular disease. This study examined the impact of switching from another antipsychotic to ziprasidone on the distribution of the number of risk factors for MetS in subjects with schizophrenia or related psychotic disorders.

Research Design And Methods: In this 1 year, open-label, prospective study, all subjects received ziprasidone 40-160 mg/day.
