The coronavirus pandemic provoked worldwide changes to the workplace, leading to rapid changes in lifestyles and working conditions. While organizations and governments struggled to develop regulations and policies, individuals were forced to find ways to manage work and life. During the pandemic and quarantine, a group of knowledge workers from around the world convened virtually and agreed to use qualitative autoethnographic methods to study how the quarantine disrupted their conventional patterns of work and care. In this article, we apply two communication perspectives-uncertainty reduction theory and re-silience-to participant diaries to understand how participants represent internal and external stressors, the efforts diarists employed to overcome those stressors, and their varying success in doing so. Post-hoc application of these communication concepts suggests that the diarists, though privileged in some ways, were not exempt from the social, professional, and emotional consequences of the pandemic and that their efforts to enact resilience were unevenly successful, especially in relation to their use of communications technology. Diarists reported struggling with uncertainty at numerous levels and that uncertainty contributed to individual emotional and cultural distress. Disruptions to work, home, and communities significantly affected wellbeing and ability to cope with challenges. Added to this were the complex and competing roles that diarists felt as they struggled to work from home, parent, and remain engaged.

Review
Central 5-hydroxytryptaminergic dorsal raphe nucleus (5-HTDRN)-bed nucleus of stria terminalis (BNST) neural circuit dysfunction is one of the important neurobiological basis of anxiety and fear disorders. Under stress, 5-hydroxytryptamine (5-HT) neurons act on BNST receptors to attenuate anxiety and fear responses or enhance anxiety and fear. In BNST, corticotropin releasing factor neurons play a role in regulating emotions by reversely regulating excitatory or inhibitory 5-HT neurons. The composition of 5-HTDRN-BNST neural circuit, the pathological changes of 5-HTDRN-BNST neural circuit function damage under stress, and the effects of 5-HTDRN-BNST neural circuit on anxiety disorder, panic disorder and post-traumatic stress disorder were analyzed and are summarized in this paper. The characteristics of functional changes of the neural circuit and its effects on brain functional activities provide a basis and ideas for the treatment of anxiety and fear disorders through the regulation of 5-HTDRN-BNST neural circuit, and they also provide a new perspective for understanding the pathological mechanism of such diseases.

AIM
In a previous study, we reported that watching two-dimensional videos of earthquakes significantly reduced sympathetic nerve activity in healthy young adults. In the present study, we aimed to investigate the emotional responses to earthquakes using immersive virtual reality (VR), which can provide a more realistic experience.
METHODS
In total, 24 healthy young adults (12 males, 21.4 ± 0.2 years old) participated. Participants were required to watch earthquake and neutral videos while wearing a head-mounted display and near-infrared spectroscopy (NIRS), during which physiological signals, including pulse rate and cerebral blood flow (CBF) in the dorsolateral prefrontal cortex, were measured. We also analyzed changes in sympathetic and parasympathetic indices and obtained seven emotion ratings: valence, arousal, dominance, fear, astonishment, anxiety, and panic.
RESULTS
The VR earthquake videos evoked negative subjective emotions, and the pulse rate significantly decreased. Sympathetic nerve activity tended to decrease, whereas CBF in the left prefrontal cortex showed a slight increase, although this was not significant.
CONCLUSIONS
This study showed that measurements combined with NIRS and immersive VR have the potential to capture emotional responses to different stimuli.

Review
Panic disorder is a common psychiatric diagnosis characterized by acute, distressing somatic symptoms that mimic medically-relevant symptoms. As a result, individuals with panic disorder overutilize personal and healthcare resources in an attempt to diagnose and treat physical symptoms that are often medically benign. A biobehavioral perspective on these symptoms is needed that integrates psychological and medical knowledge to avoid costly treatments and prolonged suffering. This narrative review examines six common somatic symptoms of panic attacks (non-cardiac chest pain, palpitations, dyspnea, dizziness, abdominal distress, and paresthesia), identified in the literature as the most severe, prevalent, or critical for differential diagnosis in somatic illness, including long COVID. We review somatic illnesses that are commonly comorbid or produce panic-like symptoms, their relevant risk factors, characteristics that assist in distinguishing them from panic, and treatment approaches that are typical for these conditions. Additionally, this review discusses key factors, including cultural considerations, to assist healthcare professionals in differentiating benign from medically relevant symptoms in panic sufferers.

This editorial explores the role of hyperactivity and social rhythm dysregulation in bipolar disorder (BD) and related syndromes. Social Rhythm Dysregulation Syndrome (DYMERS) is proposed as a common vulnerability across various disorders, including panic disorder (PD), attention deficit hyperactivity disorder, and post-traumatic stress disorder. A study conducted on a sample of elderly individuals participating in an active aging study investigated whether individuals with PD exhibit higher biological rhythm dysregulation compared to those without PD. The sample, consisting of 119 individuals, revealed that those with a lifetime PD diagnosis scored significantly higher on the dysregulation of biological rhythms scale compared to those without panic disorder. A higher prevalence of depressive episodes was found in individuals with PD at the time of the interview. Notably, a small sample of elderly individuals with panic disorder, voluntarily selected for a physical exercise trial, showed a significantly higher level of dysregulation of social rhythms compared to those without panic disorder. This study opens a debate on the accuracy of paper and pencil screening tests for bipolar disorders, especially regarding false positives in individuals with panic disorder. Our hypothesis is that DYMERS could be a shared vulnerability substrate for various disorders, serving as a basis for bipolar onset in the presence of a hyperactivity profile, even with genetic features. The data collected from older adults suggest that social rhythm dysregulation is a typical feature of PD, regardless of the coexistence of a depressive episode. While the study has limitations due to a small sample size, the findings warrant careful analysis and suggest the need for larger-scale replication studies. If confirmed, the dysregulation of rhythms and its association with depressive disorders highlight a significant area of vulnerability for serious psychopathological disorders, emphasizing the importance of extending research to younger populations.

In the post-epidemic era, public panic has emerged as a highly significant secondary disaster, necessitating an urgent enhancement of emergency management capabilities by governments at all levels. In order to ensure a robust assessment of the government's ability to manage public panic, it is crucial to effectively address the influence of uncertain and ambiguous factors associated with such scenarios. This paper proposes a governmental public panic emergency management capability assessment method based on fuzzy Petri nets. By analyzing the factors influencing public panic across the four evolutionary stages, namely gestation, outbreak, diffusion, and fading, we establish a hierarchical evaluation index system for assessing emergency management capabilities. Additionally, we develop a range of multi-scenario emergency management strategies. To address the challenges posed by uncertainty, randomness, fuzziness, and insufficient statistical data within the assessment index system, we introduce fuzzy Petri nets and fuzzy reasoning rules to evaluate the emergency management capability of the assessment system and derive the optimal emergency management strategy. According to example simulations, the effectiveness and practicality of models and rules constructed using fuzzy Petri nets are demonstrated, highlighting their superiority over traditional assessment methods. This comprehensive approach equips the government with a versatile toolkit for effectively managing public panic emergencies.

Antidepressants like sertraline are frequently used to treat psychiatric diseases like depression, panic disorder, and obsessive-compulsive disorder. Small-vessel vasculitis called leukocytoclastic vasculitis is defined histopathologically by immune complex-mediated vasculitis of the dermal capillaries and venules. Typically, it shows up as purpura on the lower extremities, either with or without systemic involvement. Leukocytoclastic vasculitis can be idiopathic but it can also happen in conjunction with several medications. Here, we present data on sertraline-induced leukocytoclastic vasculitis in a patient with major depressive disorder. To our knowledge, sertraline and other selective serotonin reuptake inhibitors have not previously been definitively linked to leukocytoclastic vasculitis, which is rare with antidepressants.

BACKGROUND
Gray matter alterations play a role in the panic disorder's pathophysiology origin. However, the current literature seemed inadequate to reach a consistent conclusion. Therefore, we conducted this gray matter meta-analysis on panic disorder.
METHODS
A systematic review and a voxel-wise meta-analysis based on voxel-based morphometry were conducted for the gray matter studies in patients with panic disorder. The Seed-based d Mapping toolbox was applied for the voxel-wise meta-analysis. Fourteen gray matter studies (954 subjects) were enrolled in the current meta-analysis. The subgroup analysis of typical-onset versus late-onset patients was also performed. At last, the clinical severity was meta-regressed with gray matter alterations.
RESULTS
Significant gray matter alterations were found in the left para-cingulate gyrus and the right amygdala of panic disorder patients. The subgroup analysis of typical-onset panic disorder patients showed a similar pattern. However, gray matter alterations were demonstrated in the bilateral opercular cortex of late-onset panic disorder patients. A significant association between the clinical severity and the gray matter alterations was found in the fronto-cingulate regions of panic disorder patients.
CONCLUSION
Gray matter alterations might represent a significant pillar of panic disorder's neurobiology, especially for the amygdala, cingulate, and frontal regions. Future gray matter studies in panic disorder should be needed to reconfirm this pattern of gray matter alterations.

OBJECTIVE
This study proposes a way of increasing dataset sizes for machine learning tasks in Internet-based Cognitive Behavioral Therapy through pooling interventions. To this end, it (1) examines similarities in user behavior and symptom data among online interventions for patients with depression, social anxiety, and panic disorder and (2) explores whether these similarities suffice to allow for pooling the data together, resulting in more training data when prediction intervention dropout.
METHODS
A total of 6418 routine care patients from the Internet Psychiatry in Stockholm are analyzed using (1) clustering and (2) dropout prediction models. For the latter, prediction models trained on each individual intervention's data are compared to those trained on all three interventions pooled into one dataset. To investigate if results vary with dataset size, the prediction is repeated using small and medium dataset sizes.
RESULTS
The clustering analysis identified three distinct groups that are almost equally spread across interventions and are instead characterized by different activity levels. In eight out of nine settings investigated, pooling the data improves prediction results compared to models trained on a single intervention dataset. It is further confirmed that models trained on small datasets are more likely to overestimate prediction results.
CONCLUSION
The study reveals similar patterns of patients with depression, social anxiety, and panic disorder regarding online activity and intervention dropout. As such, this work offers pooling different interventions' data as a possible approach to counter the problem of small dataset sizes in psychological research.
