Background: Visual changes due to hyperglycemia in diabetes are not uncommon. While blurred vision is a well-established sequela of chronic hyperglycemia, homonymous hemianopia with or without electroclinical seizures is much rarer and can be mistaken for migraine, temporal arteritis, or ischemia of the central nervous system.

Methods: This article analyzed case studies for 3 patients (67M, 68M, 52F) presenting with complex visual phenomena, from 3 to 42 days duration, including pathogenesis, clinical findings, management, and follow-up.

Background: Digital mental health (DMH) interventions incorporating elements that adapt to the evolving needs of consumers have the potential to further our understanding of the optimal intensity of therapist assistance and inform stepped-care models.

Objective: The primary objective was to compare the efficacy of a transdiagnostic biopsychosocial DMH program, with or without therapist assistance for adults with subthreshold symptoms or a diagnosis of anxiety or depression.

Methods: In a randomized adaptive clinical trial design, all participants had access to the DMH program, with eligibility to have their program augmented with therapist assistance determined by program engagement or symptom severity.

Background: Anxiety and depression are leading causes of disease worldwide, requiring timely access to evidence-based treatment. Digital mental health (dMH) interventions increase accessibility to evidence-based psychological services delivered in a variety of web-based formats (eg, self-help and therapist-assisted interventions). Robust and rigorous studies of adaptive web-based intervention designs are scarce.

Article Synopsis
  • The study explores the trait-impulsivity hypothesis, suggesting that impulsivity is fundamental to the symptoms of ADHD and ODD.
  • Researchers used network analysis to examine how different aspects of ADHD (inattention and hyperactivity/impulsivity) and ODD (anger, vindictiveness, defiance) relate to various components of impulsivity measured by the UPPS-P model.
  • Results indicated that ADHD and ODD dimensions have unique associations with different types of impulsivity, adding new insights to current theories on impulsivity in these disorders.

Revised reinforcement sensitivity theory (r-RST) of personality is a major neuropsychological theory of motivation, emotion and personality. This paper presents the results of a study examining: (1) the factor structure of the Reinforcement Sensitivity Theory of Personality Questionnaire (RST-PQ) using confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM); and (2) the relationships of the r-RST constructs in the RST-PQ with attention deficit hyperactivity disorder (ADHD) symptom groups of inattention (IA) and hyperactivity/impulsivity (HI). A total of 572 (Sample 1) and 309 (Sample 2) adults completed the RST-PQ.

This review critically evaluates the literature concerning the impact of visual appearance cues (including colour, foam, and cloudiness) on people's perception in the beer category. The authors assess both the sensory expectations that are elicited by the visual appearance of beer, and the extent to which those expectations carry-over to influence the actual tasting experience. Beer is a particularly intriguing category to study since the differing production rules in different countries mean that there is not always the same scope to modify the colour in order to meet perceived consumer demands.

The Personality Inventory for , Brief Form (PID-5-BF), is a 25-item self-report questionnaire that measures the severity of the proposed personality pathology constructs of negative affectivity, detachment, antagonism, disinhibition, and psychoticism. The current study used exploratory factor analysis, exploratory structural equation modeling, and confirmatory factor analysis to examine the support for the theoretically proposed 5-factor model. In total, 502 adults (male = 182, female = 320, age = 18-67 years [ = 28.

Receiver operating characteristic curve analysis was used to examine and compare the diagnostic accuracy of the Conners 3-Parent Short Form (C 3-P(S)), and the Conners 3-Teacher Short Form (C 3-T(S)) inattention and hyperactivity/impulsivity scales, and the Child Behavior Checklist (CBCL) and Teacher's Report Form (TRF) attention problems scales, to distinguish those with and without attention deficit/hyperactivity disorder (ADHD). It also examined and compared the diagnostic accuracy of the C 3-P(S) and C 3-T(S) Aggression (AG) scales, and the CBCL and TRF Aggressive Behavior (AB) scales, to distinguish those with and without oppositional defiant disorder (ODD). The study used archival data ( = 150-261) involving a large group of clinic-referred children aged between 6 and 11 years who had been interviewed for clinical diagnosis of ADHD and ODD using the Anxiety Disorders Interview Schedule for Children (ADISC-IV) as the reference standard, and then administered one or more of the screening measures.

Background: Miscarriage is a common event in Australia and is estimated to occur in up to one in four confirmed pregnancies. Prior research has demonstrated that miscarriage is associated with significant distress, grief and loss, and in some cases clinically significant levels of depression, anxiety, and Post Traumatic Stress Disorder. Despite these consequences for women's emotional and mental health, studies have commonly found that women feel that healthcare providers often lack empathy, support, and acknowledgement of their loss.
