Macronutrient composition of sea otter diet with respect to recolonization, life history, and season in southern Southeast Alaska.

The sea otter () population of Southeast Alaska has been growing at a higher rate than other regions along the Pacific coast. While good for the recovery of this endangered species, rapid population growth of this apex predator can create a human-wildlife conflict, negatively impacting commercial and subsistence fishing. Previous foraging studies throughout the sea otter range have shown they will reduce invertebrate prey biomass when recolonizing an area.

Selective serotonin reuptake inhibitors and the risk of type 2 diabetes mellitus in youths.

Background: Selective serotonin reuptake inhibitors (SSRIs) have been associated with type 2 diabetes mellitus (T2DM) in youths, possibly via 5-HT, H receptors and serotonin transporter (SERT). SSRIs have similar affinity for SERT but variable affinity for 5-HT and H. This study assessed whether SSRIs with strong affinity for 5-HT and H (relative to SERT) were associated with T2DM risk compared with weak-affinity SSRIs.

Prescribing Trends of Antidepressants and Psychotropic Coprescription for Youths in UK Primary Care, 2000-2018.

Background: There is lack of recent information on the prescribing trends of antidepressants and coprescription with other psychotropic medications in the United Kingdom (UK) pediatric population.

Methods: Using the Clinical Practice Research Datalink, we estimated the annual rates of patients newly prescribed an antidepressant (selective serotonin reuptake inhibitors (SSRIs), other newer generation antidepressants, and tricyclic antidepressants (TCAs)) and the percentage of new users of antidepressants with a same-day coprescription for other psychotropic medications. We also estimated the prevalence of patients with antidepressant prescriptions and percentage of coprescription for other psychotropic medications.

Paranoia in patients attending child and adolescent mental health services.

Objective: Paranoia may be particularly prevalent during adolescence, building on the heightened social vulnerabilities at this age. Excessive mistrust may be corrosive for adolescent social relationships, especially in the context of mental health disorders. We set out to examine the prevalence, symptom associations, and persistence of paranoia in a cohort of young people attending child and adolescent mental health services.

The assessment of paranoia in young people: Item and test properties of the Bird Checklist of Adolescent Paranoia.

Background: Precise assessment tools for psychotic experiences in young people may help identify symptoms early and facilitate advances in treatment. In this study we provide an exemplar - with a paranoia scale for youth - for improving measurement precision for psychotic experiences using item response theory (IRT). We evaluate the psychometric properties of the new measure, test for measurement invariance, and assess its potential for computerised adaptive testing (CAT).
