The role of affective temperament in the genesis and outcome of major mood disorders is well studied, but there are only a few reports on the relationship between panic disorder (PD) and affective temperaments. Accordingly, we aimed to study the distribution of affective temperaments (depressive (DE); cyclothymic (CT); irritable (IRR); hyperthymic (HT) and anxious (ANX)) among outpatients with PD. Affective temperaments of 118 PD outpatients (80 females and 38 males) with or without agoraphobia but without any other psychiatric disorder at the time of inclusion were evaluated using the Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) and compared with the affective temperament scores of control subjects. All patients were followed up for at least 1.5 years in order to detect the onset of any major affective disorders, substance use disorders and suicide attempts. Among females, the dominant ANX and DE temperaments were four and three times as common as in a large normative Hungarian sample (for both cases < 0.01). Among male PD patients, only the dominant DE temperament was slightly overrepresented in a non-significant manner. Females with PD obtained significantly higher scores on ANX, DE and CT subscales of the TEMPS-A, whereas males with PD showed significantly higher scores on ANX, DE and HT temperament subscales compared with the members of a large normative Hungarian sample and also with a gender- and age-matched control group. During the follow-up, newly developed unipolar major depression and bipolar spectrum (bipolar I or II and cyclothymic) disorders appeared in 64% and 22% of subjects, respectively. Our preliminary findings suggest that a specific, ANX-DE-CT affective temperament profile is characteristic primarily for female patients, and an ANX-DE-HT affective temperament profile is characteristic for male patients with PD, respectively. These findings are in line with expectations because PD is an anxiety disorder par excellence on the one hand, whereas, on the other hand, it is quite frequently comorbid with mood (including bipolar) disorders.

Anxiety disorders (ADs) are the most common form of mental disorder that affects millions of individuals worldwide. Although physiological studies have revealed the neural circuits related to AD symptoms, how AD-associated genes are spatiotemporally expressed in the human brain still remains unclear. In this study, we integrated genome-wide association studies of four human AD subtypes-generalized anxiety disorder, social anxiety disorder, panic disorder, and obsessive-compulsive disorder-with spatial gene expression patterns. Our investigation uncovered a novel division among AD-associated genes, marked by significant and distinct expression enrichments in the cerebral nuclei, limbic, and midbrain regions. Each gene cluster was associated with specific anxiety-related behaviors, signaling pathways, region-specific gene networks, and cell types. Notably, we observed a significant negative correlation in the temporal expression patterns of these gene clusters during various developmental stages. Moreover, the specific brain regions enriched in each gene group aligned with neural circuits previously associated with negative decision-making and anxious temperament. These results suggest that the two distinct gene clusters may underlie separate neural systems involved in anxiety. As a result, our findings bridge the gap between genes and neural circuitry, shedding light on the mechanisms underlying AD-associated behaviors.

PURPOSE
Few studies have examined the role of selenium in anxiety. This study aimed to evaluate the association between serum selenium concentrations and anxiety disorders and symptoms in children.
DESIGN AND METHODS
This study utilized data from 831 children participating in the China Jintan Child Cohort Study (mean age = 12.67 years; 46.1% female). Serum selenium samples were collected and anxiety was assessed using the Chinese version of the Screen for Child Anxiety Related Disorders. Six types of anxiety scores were calculated, including total anxiety, panic/somatic, generalized anxiety, separation anxiety, social anxiety, and school phobia.
RESULTS
Controlling for covariates, children with lower serum selenium concentrations were more likely to meet clinical cutoffs for total anxiety (OR = 0.992, p < 0.01), panic/somatic disorder (OR = 0.993, p < 0.05), generalized anxiety disorder (OR = 0.990, p < 0.05), social anxiety disorder (OR = 0.991, p < 0.01), and school phobia (OR = 0.989, p < 0.01), but not separation anxiety (OR = 1.000, p > 0.05). Controlling for covariates, lower serum selenium concentrations were also associated with higher continuous total anxiety, generalized anxiety, and school phobia scores (p < 0.05).
CONCLUSIONS
Lower serum selenium concentrations were associated with higher anxiety. To our knowledge, this was the first study to examine the relationship between serum selenium and anxiety disorders in a sample of children. Results indicate an association between children's micronutrient levels and anxiety disorders.
PRACTICE IMPLICATIONS
Improving child nutrition may be a promising strategy to help reduce childhood anxiety.

Review
Panic disorder (PD) is a common and debilitating neuropsychiatric disorder characterized by panic attacks coupled with excessive anxiety. Both genetic factors and environmental factors play an important role in PD pathogenesis and response to treatment. However, PD is clinically heterogeneous and genetically complex, and the exact genetic or environmental causes of this disorder remain unclear. Various approaches for detecting disease-causing genes have recently been made available. In particular, genome-wide association studies (GWAS) have attracted attention for the identification of disease-associated loci of multifactorial disorders. This review introduces GWAS of PD, followed by a discussion about the limitations of GWAS and the major challenges facing geneticists in the post-GWAS era. Alternative strategies to address these challenges are then proposed, such as epigenome-wide association studies (EWAS) and rare variant association studies (RVAS) using next-generation sequencing. To date, however, few reports have described these analyses, and the evidence remains insufficient to confidently identify or exclude rare variants or epigenetic changes in PD. Further analyses are therefore required, using sample sizes in the tens of thousands, extensive functional annotations, and highly targeted hypothesis testing.

Meta-Analysis Review
Comparative efficacy and acceptability of psychotherapies for panic disorder with or without agoraphobia: systematic review and network meta-analysis of randomised controlled trials.
BACKGROUND
Psychotherapies are the treatment of choice for panic disorder, but which should be considered as first-line treatment is yet to be substantiated by evidence.
AIMS
To examine the most effective and accepted psychotherapy for the acute phase of panic disorder with or without agoraphobia via a network meta-analysis.
METHOD
We conducted a systematic review and network meta-analysis of randomised controlled trials (RCTs) to examine the most effective and accepted psychotherapy for the acute phase of panic disorder. We searched MEDLINE, Embase, PsycInfo and CENTRAL, from inception to 1 Jan 2021 for RCTs. Cochrane and PRISMA guidelines were used. Pairwise and network meta-analyses were conducted using a random-effects model. Confidence in the evidence was assessed using Confidence in Network Meta-Analysis (CINeMA). The protocol was published in a peer-reviewed journal and in PROSPERO (CRD42020206258).
RESULTS
We included 136 RCTs in the systematic review. Taking into consideration efficacy (7352 participants), acceptability (6862 participants) and the CINeMA confidence in evidence appraisal, the best interventions in comparison with treatment as usual (TAU) were cognitive-behavioural therapy (CBT) (for efficacy: standardised mean differences s.m.d. = -0.67, 95% CI -0.95 to -0.39; CINeMA: moderate; for acceptability: relative risk RR = 1.21, 95% CI -0.94 to 1.56; CINeMA: moderate) and short-term psychodynamic therapy (for efficacy: s.m.d. = -0.61, 95% CI -1.15 to -0.07; CINeMA: low; for acceptability: RR = 0.92, 95% CI 0.54-1.54; CINeMA: moderate). After removing RCTs at high risk of bias only CBT remained more efficacious than TAU.
CONCLUSIONS
CBT and short-term psychodynamic therapy are reasonable first-line choices. Studies with high risk of bias tend to inflate the overall efficacy of treatments. Results from this systematic review and network meta-analysis should inform clinicians and guidelines.

BACKGROUND
Anxious-depressive attack (ADA) is a symptom complex that comprises sudden intense feelings of anxiety or depression, intrusive rumination of regretful memories or future worries, emotional distress due to painful thoughts, and coping behaviors to manage emotional distress. ADA has been observed trans-diagnostically across various psychiatric disorders. Although the importance of ADA treatment has been indicated, a scale to measure the severity of ADA has not been developed. This study aimed to develop an Anxious-Depressive Attack Severity Scale (ADAS) to measure the severity of ADA symptoms and examine its reliability and validity.
METHODS
A total of 242 outpatients responded to a questionnaire and participated in an interview, which were designed to measure the severity of ADA, depressive, anxiety, anxious depression, and social anxiety symptoms. Based on the diagnostic criteria for ADA, 54 patients were confirmed to have ADA and were included in the main study analyses.
RESULTS
The exploratory factor analysis of the ADAS identified a two factor structure: severity of ADA symptoms and ADA frequency and coping behaviors. McDonald's ωt coefficients were high for the overall scale and the first factor (ωt = .78 and ωt = .83, respectively) but low for the second factor (ωt = .49). The ADAS score was significantly positively correlated with clinical symptoms related to anxiety and depression.
CONCLUSION
The present study demonstrated that the ADAS has sufficient reliability and validity; however, internal consistency was insufficient for the second factor. Overall, the ADAS has potential to be a valuable tool for use in clinical trials of ADA.

Review
BACKGROUND
Patients presenting with chest pain to general practice or emergency providers represent a unique challenge, as the differential is broad and varies widely in acuity. Importantly, most cases of chest pain in both acute and general practice settings are ultimately found to be non-cardiac in origin, and a substantial proportion of patients experiencing non-cardiac chest pain (NCCP) suffer significant disability. In light of emerging evidence that mental health providers can serve a key role in the care of patients with NCCP, knowledge of the differential diagnosis, psychiatric co-morbidities, and therapeutic techniques for NCCP would be of great use to both consultation-liaison (C-L) psychiatrists and other mental health providers.
METHODS
We reviewed prior published work on (1) the appropriate medical workup of the acute presentation of chest pain, (2) the relevant medical and psychiatric differential diagnosis for chest pain determined to be non-cardiac in origin, (3) the management of related conditions in psychosomatic medicine, and (4) management strategies for patients with NCCP.
RESULTS
We identified key differential diagnostic and therapeutic considerations for psychosomatic medicine providers in 3 different clinical contexts: acute care in the emergency department, inpatient C-L psychiatry, and outpatient C-L psychiatry. We also identified several gaps in the literature surrounding the short-term and long-term management of NCCP in patients with psychiatric etiologies or co-morbid psychiatric conditions.
CONCLUSIONS
Though some approaches to the care of patients with NCCP have been developed, more work is needed to determine the most effective management techniques for this unique and high-morbidity population.

Meta-Analysis
BACKGROUND
The clinical presentation of panic disorder and panic attack overlaps many symptoms typically experienced in coronary heart disease (CHD). Etiological links between panic disorder and CHD are controversial and remain largely tenuous. This systematic review aims to pool together data regarding panic disorder with respect to incident CHD or myocardial infarction.
METHODS/DESIGN
Electronic databases (MEDLINE, EMBASE, PsycINFO and SCOPUS) will be searched using a search strategy exploding the topics for CHD and panic disorder. Authors and reference lists of included studies will also be contacted to identify additional published and unpublished studies. Eligibility criteria are as follows:
POPULATION
persons without CHD who meet criteria for panic disorder, panic attack, anxiety neurosis or elevated panic disorder symptoms; Comparison: persons without CHD who do not meet criteria for panic disorder, panic attack, anxiety neurosis or elevated panic disorder symptoms;
OUTCOME
verified fatal and non-fatal CHD at follow-up; including coronary revascularization procedure, coronary artery disease, and myocardial infarction. Studies adopting self-report CHD will be ineligible. Screening will be undertaken by two independent reviewers with disagreements resolved through discussion. Data extraction will include original data specified as hazard ratios, risk ratios, and original cell data if available. Risk of bias assessment will be undertaken by two independent reviewers. Meta-analytic methods will be used to synthesize the data collected relating to the CHD outcomes with Cochrane Review Manager 5.3.
DISCUSSION
This systematic review aims to clarify whether panic disorder is associated with elevated risk for subsequent CHD. An evaluation of the etiological links between panic disorder with incident CHD might inform evidence-based clinical practice and policy concerning triaging chest pain patients, diagnostic assessment, and psychiatric intervention with panic disorder patients.

Although accumulating evidence suggests that inflammatory processes play a role in the pathophysiology of mental disorders, few studies have investigated this matter in panic disorder (PD). Furthermore, no studies to date have evaluated cytokine levels in drug-naïve patients with PD. Therefore, little is known about the presence of inflammation at the onset of this disorder. The aim of the present study was to determine the levels of the proinflammatory interleukins IL-1B and IL-2R and the anti-inflammatory cytokine IL-10 in drug-naïve PD patients. Analysis of serum chemokine levels revealed increased proinflammatory activity in the early phase of PD through increased IL-2R and IL-1B levels and a decrease in IL-10 levels in drug-naïve PD patients compared to matched healthy controls. Neurotransmitters and neurocircuits that are targets of inflammatory responses are discussed, followed by an examination of brain-immune interactions as risk factors for PD. This study is the first to identify a proinflammatory cytokine response in drug-naïve PD subjects. These findings indicate that treatments targeting proinflammatory markers may ameliorate anxiety symptoms in PD patients.

Review
Critical neuropsychobiological analysis of panic attack- and anticipatory anxiety-like behaviors in rodents confronted with snakes in polygonal arenas and complex labyrinths: a comparison to the elevated plus- and T-maze behavioral tests.
OBJECTIVE:
To compare prey and snake paradigms performed in complex environments to the elevated plus-maze (EPM) and T-maze (ETM) tests for the study of panic attack- and anticipatory anxiety-like behaviors in rodents.
METHODS:
PubMed was reviewed in search of articles focusing on the plus maze test, EPM, and ETM, as well as on defensive behaviors displayed by threatened rodents. In addition, the authors' research with polygonal arenas and complex labyrinth (designed by the first author for confrontation between snakes and small rodents) was examined.
RESULTS:
The EPM and ETM tests evoke anxiety/fear-related defensive responses that are pharmacologically validated, whereas the confrontation between rodents and snakes in polygonal arenas with or without shelters or in the complex labyrinth offers ethological conditions for studying more complex defensive behaviors and the effects of anxiolytic and panicolytic drugs. Prey vs. predator paradigms also allow discrimination between non-oriented and oriented escape behavior.
CONCLUSIONS:
Both EPM and ETM simple labyrinths are excellent apparatuses for the study of anxiety- and instinctive fear-related responses, respectively. The confrontation between rodents and snakes in polygonal arenas, however, offers a more ethological environment for addressing both unconditioned and conditioned fear-induced behaviors and the effects of anxiolytic and panicolytic drugs.
