Recently, the network theory of psychopathology has arisen as a framework for thinking about mental health. Network theory challenges three common assumptions psychological problems are caused by disease entities that exist independently of their signs and symptoms, classification and diagnosis of psychological problems should follow a medical model, and psychological problems are caused by diseases or aberrations in the brain. Conversely, network theory embraces other assumptions that are well accepted in clinical practice (e.g., the interaction of thoughts, behaviors, and emotions, as posited in cognitive-behavioral therapies) and integrates those assumptions into a coherent framework for research and practice. In this article, the authors review developments in network theory by focusing on anxiety-related conditions, discuss future areas for change, and outline implications of network theory for research and clinical practice.Although trauma exposure is a global phenomenon, trauma reactions vary considerably across cultures. Western psychiatric diagnoses, such as posttraumatic stress disorder (PTSD), may be limited in capturing the breadth of trauma reactions in cross-cultural contexts. Instead, cross-cultural instruments should examine locally relevant reactions, such as idioms of distress and explanatory models of illness, and account for ongoing stress and adversity. This article explains the need for complementing traditional trauma assessment approaches, how to create culturally sensitive instruments, the style and stance of practicing cultural humility when administering instruments, how to account for ongoing trauma and adversity, and ways to incorporate findings into treatment. These steps can improve culturally sensitive and comprehensive trauma assessment to capture universal and culturally relevant trauma reactions.Although psychedelics initially showed promise in treating anxiety disorders, psychedelics were criminalized and research halted in the early 1970s. A subsequent resurgence of research into psychiatric benefits of psychedelic-assisted psychotherapy in the last 20 years has led to a potential paradigm shift in the treatment of numerous psychiatric disorders, including anxiety disorders. Despite accumulating evidence and likely U.S. Food and Drug Administration approval in the next 2-3 years, the emerging field of psychedelic medicine faces several challenges. Obstacles include ongoing barriers on the regulatory level, lack of education, stigma among mental health clinicians, cost and scalability, and a dearth of specialized personnel prepared to provide these treatments. Deeper issues of ethical responsibility and inclusivity also exist given the historical discovery and use of psychedelics by indigenous peoples throughout the world as well the ongoing disparities in mental health delivery and access within psychiatry and psychedelic research.Cognitive-behavioral therapy (CBT) is a first-line, empirically supported intervention for anxiety disorders. CBT refers to a family of techniques that are designed to target maladaptive thoughts and behaviors that maintain anxiety over time. Several individual CBT protocols have been developed for individual presentations of anxiety. The article describes common and unique components of CBT interventions for the treatment of patients with anxiety and related disorders (i.e., panic disorder, social anxiety disorder, generalized anxiety disorder, obsessive-compulsive disorder, posttraumatic stress disorder, prolonged grief). Recent strategies for enhancing the efficacy of CBT protocols are highlighted as well.Mind-body interventions have gained increasing popularity for use with anxiety symptoms; however, it is unclear what role they play in the treatment of anxiety disorders, such as generalized anxiety disorder, panic disorder, and social anxiety disorder. Although psychopharmacology and psychotherapy treatment interventions are available, mind-body interventions may be low-stigma options that can serve as effective alternatives. The goal of this review is to provide clinicians with an overview of high-quality studies for the most well researched mind-body interventions. This review involved a search of the primary literature, including meta-analyses, systematic reviews, and randomized controlled trials (RCTs), that evaluated mind-body interventions for the treatment of anxiety disorders. When published evidence was limited, lower-quality studies were reviewed. Overall, data were limited on the efficacy of most mind-body modalities for anxiety disorders. The highest-quality data existed for yoga, mindfulness-based interventions, and applied relaxation for anxiety disorders. However, findings were sometimes inconsistent across studies, and some studies were limited by small sample sizes, poorly defined randomization and blinding procedures, and inadequate control groups. Although not enough data exist to recommend mind-body interventions as primary treatment options, they may be considered as part of a larger treatment plan given their relatively low levels of risk. Future steps for researchers include conducting additional RCTs with adequate control groups, comparing mind-body treatments with existing treatments, and examining long-term effects of mind-body interventions.Losing a loved one is one of life's greatest stressors. Although most bereaved individuals navigate through a period of intense acute grief that lessens with time, approximately 10% will develop a prolonged grief condition. This review provides an overview of the course of grief and describes risk factors for developing prolonged grief disorder. The evolution of the prolonged grief disorder diagnosis, including the latest criteria sets for ICD-11 and DSM-5, as well as common comorbid conditions and differential diagnosis are discussed. Clinically useful self-report and clinician-rated measures for assessing symptom constructs and overall prolonged grief disorder severity, evidence-based psychotherapies (such as complicated grief treatment), as well as evidence about pharmacologic approaches are presented. Finally, the authors discuss important future directions, including a potential increase in prolonged grief disorder cases due to the COVID-19 pandemic.In this review, the author examines the evidence for psychopharmacologic treatments among adults for generalized anxiety disorder, panic disorder, and social anxiety disorder derived from clinical trials. For each disorder, major categories of drugs are reviewed, and then the evidence-based medications in each category are discussed. The author reviews key safety and tolerability considerations for each of the medications or classes. Evidence-based dosing for most specific agents is displayed in a comprehensive reference table. Subsequently, the author synthesizes the available information to suggest a pragmatic stepwise approach to treatment that accounts for patient-specific factors. To inform the guidance, the author incorporates and refines perspectives from treatment guidelines already written by clinical professional organizations. The author also briefly reviews the relatively new quantitative systematic review methodology of network meta-analysis (NMA) and discusses how NMA may help guide pharmacologic treatment sequencing decisions in the future by way of ranking treatments according to effect size and the relative amount of study to which treatments have been subject. Caveats of NMA studies are briefly discussed, as are results of recent NMAs regarding the pharmacologic treatment of anxiety disorders.Recent election surprises, regime changes, and political shocks indicate that political agendas have become more fast-moving and volatile. The ability to measure the complex dynamics of agenda change and capture the nature and extent of volatility in political systems is therefore more crucial than ever before. This study proposes a definition and operationalization of volatility that combines insights from political science, communications, information theory, and computational techniques. The proposed measures of fractionalization and agenda change encompass the shifting salience of issues in the agenda as a whole and allow the study of agendas across different domains. We evaluate these metrics and compare them to other measures such as issue-level survival rates and the Pedersen Index, which uses public-opinion poll data to measure public agendas, as well as traditional media content to measure media agendas in the UK and Germany. We show how these measures complement existing approaches and could be employed in future agenda-setting research.Perineuronal nets (PNNs) are condensed extracellular matrix (ECM) assemblies of polyanionic chondroitin sulfate proteoglycans, hyaluronan, and tenascins that primarily wrap around GABAergic parvalbumin (PV) interneurons. During development, PNN formation terminates the critical period of neuroplasticity, a process that can be reversed by experimental disruption of PNNs. Perineuronal nets also regulate the intrinsic properties of the enclosed PV neurons thereby maintaining their inhibitory activity. Recent studies have implicated PNNs in central nervous system diseases as well as PV neuron dysfunction; consequently, they have further been associated with altered inhibition, particularly in the genesis of epilepsy. A wide range of seizure presentations in human and rodent models exhibit ECM remodeling with PNN disruption due to elevated protease activity. Inhibition of PNN proteolysis reduces seizure activity suggesting that PNN degrading enzymes may be potential novel therapeutic targets.Chinese students' issues and concerns of studying abroad amid the COVID-19 pandemic have been largely neglected in the tourism and hospitality education research. Based on the actor-network perspective, this paper explores the network of issues and concerns of Chinese students who have planned to study abroad. In-depth interviews, observations, and open-ended questionnaires are employed with a purposive sample of 16 hospitality students from a university in Macau. We identify five major concerns and issues namely health risk, dissatisfaction with online study, feeling difficult to get into a top university, discrimination of Chinese in the West, and perception of restricted opportunity to make a cross-cultural exchange.Corporate elite studies have for long investigated networks of interlocking directorates to test and corroborate key theoretical expectations regarding the cohesive organization of such an elite and their ability and willingness to act on behalf of general business interests. These studies typically collect data on a list of 50, 100, 200 or 500 corporations ranked by economic size, sometimes stratified in sectors. The sampling approach often follows previous studies in order to increase comparability. These relatively arbitrary sampling practices are problematic because they impact the empirical results and our therefore the conclusions drawn from it. GSK-3 inhibitor Using a sample of 3251 Canada-based corporations, we establish that indeed different sampling criteria - that is sample size, proportion of financial firms, inclusion of state-owned enterprises and so on - significantly impacts network properties of corporate elite networks. We establish rather disturbing differences, especially for smaller sample sizes ( less then 100).
