Examining the relationship between emotion regulation, sleep quality, and anxiety disorder diagnosis.

Anxiety disorders are highly comorbid with sleep disturbance and have also been associated with deficits in emotion regulation, the ability to control and express emotions. However, the extent to which specific dimensions of sleep disturbance and emotion regulation are associated with anxiety diagnosis is not well-explored. This study examined dimensions of emotion regulation and sleep disturbance that may predict greater likelihood of anxiety diagnosis using novel machine learning techniques.

State mechanisms of change in eating disorder symptoms and fears during an online imaginal exposure treatment for eating disorders.

Anxiety and fear are key characteristics of eating disorders (EDs). Exposure therapy is a specific type of intervention aimed at reducing fear and anxiety and is efficacious in treating a variety of anxiety and related disorders. A growing body of research suggests that exposure therapy is also efficacious for the treatment of EDs.

Effect of cognitive behavioural therapy and yoga for generalised anxiety disorder on sleep quality in a randomised controlled trial: the role of worry, mindfulness, and perceived stress as mediators.

Sleep disturbances are present in ~65% of individuals with generalised anxiety disorder (GAD). Although both Kundalini yoga (KY) and cognitive behavioural therapy (CBT) are effective treatment options for GAD, little is known about how these treatments compare in improving sleep for GAD and what drives these changes. Accordingly, we examined the effects of CBT, KY, and stress education (SEdu; an attention control condition) on subjective sleep quality (as measured by the Pittsburgh Sleep Quality Index [PSQI] and Insomnia Severity Index [ISI]) in a randomised controlled trial of 226 adults with GAD (mean age 33.

Demography and space-use of Eastern Red-backed Salamanders () between mature and successional forests.

Space-use and demographic processes are critical to the persistence of populations across space and time. Despite their importance, estimates of these processes are often derived from a limited number of populations spanning broad habitat or environmental gradients. With increasing appreciation of the role fine-scale environmental variation in microgeographic adaptation, there is a need and value to assessing within-site variation in space-use and demographic patterns.

A network approach can improve eating disorder conceptualization and treatment.

Eating disorders are severe mental illnesses with the second highest mortality rate of all psychiatric illnesses. Eating disorders are exceedingly deadly because of their complexity. Specifically, eating disorders are highly comorbid with other psychiatric illnesses (up to 95% of individuals with an eating disorder have at least one additional psychiatric illness), have extremely heterogeneous presentations, and individuals often migrate from one specific eating disorder diagnosis to another.

Psychiatric Comorbidity Among Eating Disorders and Obsessive-Compulsive Disorder and Underlying Shared Mechanisms and Features: An Updated Review.

Eating disorders (EDs) are highly comorbid with obsessive-compulsive disorder (OCD), with comorbidity rates as high as 41%. In the current review, we summarize the literature regarding the prevalence of ED-OCD comorbidity. We also identify and review the literature assessing shared features (i.

Impact of preference for yoga or cognitive behavioral therapy in patients with generalized anxiety disorder on treatment outcomes and engagement.

There is some, but inconsistent, evidence to suggest that matching patient treatment preference enhances treatment engagement and outcome. The current study examined differential preferences and factors associated with treatment preference for 12-week group cognitive behavioral therapy (CBT), yoga, or stress education in 226 adults with generalized anxiety disorder (GAD; 70% female, Mean age = 33 ± 13.5).

Core eating disorder fears: Prevalence and differences in eating disorder fears across eating disorder diagnoses.

Objective: Fear and anxiety are key maintaining factors for eating disorder (ED) pathology. Maladaptive fears lead to ED behaviors and avoidance, which provide temporary relief, but ultimately reinforce the fear and contribute to a cycle that maintains the ED. To date, fears of food and weight gain are the most explored fears underlying ED pathology.

Using individual networks to identify treatment targets for eating disorder treatment: a proof-of-concept study and initial data.

Background: Eating disorders (EDs) are severe mental illnesses, with high morbidity, mortality, and societal burden. EDs are extremely heterogenous, and only 50% of patients currently respond to first-line treatments. Personalized and effective treatments for EDs are drastically needed.

Anhedonia is central for the association between quality of life, metacognition, sleep, and affective symptoms in generalized anxiety disorder: A complex network analysis.

Background: Poor quality of life, sleep problems, anhedonia, and negative metacognitions are common in anxiety and depression. To examine the nature of the relationship between these features and the role of metacognitions, anhedonia, and quality of life in anxiety and depression, we conducted a complex network analysis with items of self-report measures assessing quality of life, sleep, negative thinking styles, anxiety, and depression.

Methods: Participants were 226 treatment seeking individuals with a primary DSM-5 diagnosis of generalized anxiety disorder.

A Perfect Ten-Decoy Maps Uncover Polymerase Complexes within Reoviridae Virion.

In this issue of Structure, Kaelber et al. (2020) use cryo-EM and synthetic decoy maps to reveal the patterning of 10 polymerase complexes within FAKV, a Reoviridae family member containing 9 genome segments. Their findings support a model for FAKV assembly that has implications for the entire Reoviridae family.

Towards a precision psychiatry approach to anxiety disorders with ecological momentary assessment: the example of panic disorder.

Background: Treatments for anxiety disorders are among the most effective in psychiatry. Yet, there is considerable room for improvement.

Aim: In this paper, we discuss the value of ecological momentary assessment as a research method and clinical tool.

Assessing vulnerability to panic: a systematic review of psychological and physiological responses to biological challenges as prospective predictors of panic attacks and panic disorder.

Background: Cognitive-behavioural theories of panic disorder posit that panic attacks arise from a positive feedback loop between arousal-related bodily sensations and perceived threat. In a recently developed computational model formalising these theories of panic attacks, it was observed that the response to a simulated perturbation to arousal provided a strong indicator of vulnerability to panic attacks and panic disorder. In this review, we evaluate whether this observation is borne out in the empirical literature that has examined responses to biological challenge (eg, CO inhalation) and their relation to subsequent panic attacks and panic disorder.

Double-Stranded RNA Synthesis by Rotavirus Polymerase Mutants with Lesions at Core Shell Contact Sites.

The rotavirus polymerase VP1 mediates all stages of viral RNA synthesis within the confines of subviral particles and while associated with the core shell protein VP2. Transcription (positive-strand RNA [+RNA] synthesis) by VP1 occurs within double-layered particles (DLPs), while genome replication (double-stranded RNA [dsRNA] synthesis) by VP1 occurs within assembly intermediates. VP2 is critical for VP1 enzymatic activity; yet, the mechanism by which the core shell protein triggers polymerase function remains poorly understood.

Factors associated with depression and anxiety symptoms among children seeking treatment for obesity: A social-ecological approach.

Background: Children with overweight/obesity are more likely to exhibit symptoms of depression and anxiety than are their peers without overweight/obesity; however, the rates and correlates of depression and anxiety symptoms among children seeking obesity treatment remain unclear.

Objectives: Examine the prevalence and associated factors of depression and anxiety symptoms among treatment-seeking children with overweight/obesity.

Methods: Children 7 to 11 years old (N = 241) and their parents completed assessments before beginning family-based behavioral weight-loss treatment.

Child and parent reports of children's depressive symptoms in relation to children's weight loss response in family-based obesity treatment.

Background: Studies of the association between children's depressive symptoms and obesity treatment response show mixed results. Different measurement may contribute to the inconsistent findings, as children's depressive symptoms are often based on parent-report about their child rather than child self-report.

Objectives: We assessed both child- and parent-report of child depressive symptoms as predictors of children's obesity treatment response.

Disordered Eating Attitudes and Behaviors in Youth with Overweight and Obesity: Implications for Treatment.

Purpose Of The Review: Children with obesity experience disordered eating attitudes and behaviors at high rates, which increases their risk for adult obesity and eating disorder development. As such, it is imperative to screen for disordered eating symptoms and identify appropriate treatments.

Recent Findings: Family-based multicomponent behavioral weight loss treatment (FBT) is effective at treating childhood obesity and demonstrates positive outcomes on psychosocial outcomes, including disordered eating.
