Use of a trigger tool to describe and screen drug-related hospital admissions in older adults: the TRIGGAge retrospective cohort study.

Introduction: Drug-related hospital admissions (DRAs) can account for 5%-40% of total hospital admissions in older adults, with a significant proportion deemed preventable. To increase the detection of DRAs, in 2021, a revised trigger tool listing 21 frequent causes of admissions and medications at risk was proposed. This study aimed to describe DRAs using this trigger tool in a French acute geriatric ward and to assess the performance of the tool.

A Frustrated Antipolar Phase Analogous to Classical Spin Liquids.

The study of magnetic frustration in classical spin systems is motivated by the prediction and discovery of classical spin liquid states. These uncommon magnetic phases are characterized by a massive degeneracy of their ground state implying a finite magnetic entropy at zero temperature. While the classical spin liquid state is originally predicted in the Ising triangular lattice antiferromagnet in 1950, this state has never been experimentally observed in any triangular magnets.

Virus-host interactions predictor (VHIP): Machine learning approach to resolve microbial virus-host interaction networks.

Viruses of microbes are ubiquitous biological entities that reprogram their hosts' metabolisms during infection in order to produce viral progeny, impacting the ecology and evolution of microbiomes with broad implications for human and environmental health. Advances in genome sequencing have led to the discovery of millions of novel viruses and an appreciation for the great diversity of viruses on Earth. Yet, with knowledge of only "who is there?" we fall short in our ability to infer the impacts of viruses on microbes at population, community, and ecosystem-scales.

Triptycene-Based Tripodal Molecular Platforms.

Molecular platforms are essential components of various surface-mounted molecular devices. Here, we document the synthesis of two universal triptycene-based tripodal pedestals featuring terminal alkynes in the axial position. We showcase their versatility by incorporating them into the structures of diverse functional molecules such as unidirectional light-driven molecular motors, photoswitches, and Brownian molecular rotors using standard cross-coupling reactions.

Enhanced triplet superconductivity in next-generation ultraclean UTe.

The unconventional superconductor UTe[Formula: see text] exhibits numerous signatures of spin-triplet superconductivity-a rare state of matter which could enable quantum computation protected against decoherence. UTe[Formula: see text] possesses a complex phase landscape comprising two magnetic field-induced superconducting phases, a metamagnetic transition to a field-polarized state, along with pair- and charge-density wave orders. However, contradictory reports between studies performed on UTe[Formula: see text] specimens of varying quality have severely impeded theoretical efforts to understand the microscopic origins of the exotic superconductivity.

Regular Arrays of Rod-Shaped Molecular Photoswitches: Synthesis, Preparation, Characterization, and Selective Photoswitching within Mono- and Bilayer Systems.

We assembled photoresponsive mono- and bilayer systems with well-defined properties from rod-shaped molecules equipped with different photoswitches. Using properly chosen chromophores (diarylethene-based switch and unidirectional light-driven molecular motor), we then selectively targeted layers made of the same types of photoswitches using appropriate monochromatic light. UV-vis analysis confirmed smooth and unrestricted photoisomerization.

The Association Between Self-Reported Anxiety and Retention in Opioid Agonist Therapy: Findings From a Canadian Pragmatic Trial.

Background: Prescription-type opioid use disorder (POUD) is often accompanied by comorbid anxiety, yet the impact of anxiety on retention in opioid agonist therapy (OAT) is unclear. Therefore, this study investigated whether baseline anxiety severity affects retention in OAT and whether this effect differs by OAT type (methadone maintenance therapy (MMT) vs. buprenorphine/naloxone (BNX)).

Effect of age and speed on the step-to-step transition strategies in children.

The development and acquisition of mature walking in children is multifactorial, depending among others on foot interaction with the ground, body dynamics and the knowledge of the 'rules' stemming from the gravity field. Indeed, each step the velocity of the centre of mass must be redirected upwards. This redirection may be initiated by the trailing leg, propulsing forward and upward the body before foot contact, or later by the loading limb after the contact with the ground.

Differential effect of cannabis use on opioid agonist treatment outcomes: Exploratory analyses from the OPTIMA study.

Introduction: Conflictual evidence exists regarding the effects of cannabis use on the outcomes of opioid agonist therapy (OAT).

Variations of cannabis-related adverse mental health and addiction outcomes across adolescence and adulthood: A scoping review.

Introduction: Evidence supporting associations between cannabis use and many health outcomes is growing, however it remains unclear how such associations vary across the lifespan. We therefore aim to answer the following questions: (1) Are the risks of cannabis's adverse effects on mental health and addiction-related outcomes different in adolescents than in adults? (2) What are the relationships between these cannabis's adverse effects and (a) an individual's age at first cannabis use, (b) age at assessment, and (c) duration of cannabis use?

Methods: We searched Medline, Embase, CINAHL, and PsychINFO from inception to 18 October 2021. Two reviewers independently screened studies and descriptively synthesized results.

Background: Craving reduction is an important target in the treatment of prescription-type opioid use disorder (POUD). In this exploratory analysis, we compared the effectiveness of BUP/NX flexible model of care relative to methadone for craving reduction in individuals with POUD.

Methods: We analyzed data from a multicentric, pragmatic, 24-week open-label randomized controlled trial conducted in participants with POUD (N = 272) who were randomly assigned to BUP/NX model of care with flexible take-home dosing (n = 138) or the standard model of care with closely supervised methadone (n = 134).

The stability of covalent dative bond significantly increases with increasing solvent polarity.

It is generally expected that a solvent has only marginal effect on the stability of a covalent bond. In this work, we present a combined computational and experimental study showing a surprising stabilization of the covalent/dative bond in MeNBH complex with increasing solvent polarity. The results show that for a given complex, its stability correlates with the strength of the bond.

Preferences for research design and treatment of comorbid depression among patients with an opioid use disorder: A cross-sectional discrete choice experiment.

Background: Up to 74 % of people with an opioid use disorder (OUD) will experience depression in their lifetime. Understanding and addressing the concept of preference for depression treatments and clinical trial designs may serve as an important milestone in enhancing treatment and research outcomes. Our goal is to evaluate preferences for depression treatments and clinical trial designs among individuals with an OUD and comorbid depression.

Quantum spin-liquid states in an organic magnetic layer and molecular rotor hybrid.

The exotic properties of quantum spin liquids (QSLs) have continually been of interest since Anderson's 1973 ground-breaking idea. Geometrical frustration, quantum fluctuations, and low dimensionality are the most often evoked material's characteristics that favor the long-range fluctuating spin state without freezing into an ordered magnet or a spin glass at low temperatures. Among the few known QSL candidates, organic crystals have the advantage of having rich chemistry capable of finely tuning their microscopic parameters.

CBH and Related Carborenes.

Starting with HOOC-CBMe or CBMe as the starting material, collision-induced dissociation has produced a series of methylated analogs of didehydro--carbadodecaborane anions by sequential losses of up to 5 equiv of ethylene. These reactive intermediates are carborane analogues of doubly pyramidalized alkenes and, more distantly, arynes. Density functional theory calculations have been used to develop a proposal for the mechanism of the unusual formation of ethylene from the carborane methyl substituents.
