This study examined in detail the psychobiological correlates of panic attacks experienced in panic disorder with agoraphobia. The cognitions, affect, and physiology of the six patients were monitored during in vivo exposure to their phobic situations. The results from these case studies showed that catastrophic cognitions are the key component of panic attacks. However, there was no clear-cut evidence to support an interaction among cognitions, affect, and physiology, which has been postulated by cognitive theories to be the central component of panic attacks and panic disorder with agoraphobia.

Thirty-two patients suffering from panic disorder with agoraphobia were treated with repeated hyperventilation provocations and respiratory training, followed by exposure in vivo. The treatment was evaluated with a comprehensive set of outcome measures, including self-report questionnaires, a multitask behavioural avoidance test and continuous monitoring of panic. The treatment was found effective for the majority of patients in diminishing the frequency of panic attacks and agoraphobic avoidance. The clinical relevance of the treatment effect was evidenced by the considerable number of patients that recovered. The effect of the treatment was sustained over a three and six month follow-up period. The prognostic value of a number of variables for treatment outcome was also investigated. Three variables accounted for the majority of the variance in treatment outcome: a higher pretreatment level of agoraphobic complaints, use of psychotropic medication and a longer duration of the disorder were associated with poorer outcome. Other variables, such as the therapeutic relationship and the quality of the marital bond, had no prognostic value.

Objective: To compare patients with panic disorder with agoraphobia treated with cognitive-behavioural therapy (CBT) associated with the medication with patients treated only with medication and verify the behaviour of the cardio-respiratory symptoms of both groups. Methods: Randomized sample in the Psychiatry Institute of the Federal University of Rio de Janeiro, divided in two groups of 25 participants each. Group 1 undertook 10 weekly sessions of CBT with one hour of duration each together with medication. Group 2, Control, were administered medication that only consisted of tricyclic anti-depressants and selective inhibitors of the re-uptake of serotonin. Evaluation instruments were applied at the beginning and to the end of the interventions. Results: According to the applied scales, group 1 showed statistically more significant results than group 2, with: reduction of panic attacks, cardio-respiratory symptoms, anticipatory anxiety, agoraphobia avoidance and fear of bodily sensations. Conclusion: Exposures (in vivo and interoceptive), especially for induction symptom exercises and relaxation, were considered essential to prepare patients with panic disorder to handle future cardio-respiratory symptoms and panic attacks with agoraphobia.

While inflammation is considered a central component in the development in diabetic nephropathy, the mechanism remains unclear. The NLRP3 inflammasome acts as both a sensor and a regulator of the inflammatory response. The NLRP3 inflammasome responds to exogenous and endogenous danger signals, resulting in cleavage of procaspase-1 and activation of cytokines IL-1β, IL-18, and IL-33, ultimately triggering an inflammatory cascade reaction. This study observed the expression of NLRP3 inflammasome signaling stimulated by high glucose, lipopolysaccharide, and reactive oxygen species (ROS) inhibitor N-acetyl-L-cysteine in glomerular mesangial cells, aiming to elucidate the mechanism by which the NLRP3 inflammasome signaling pathway may contribute to diabetic nephropathy. We found that the expression of thioredoxin-interacting protein (TXNIP), NLRP3, and IL-1βwas observed by immunohistochemistry in vivo. Simultaneously, the mRNA and protein levels of TXNIP, NLRP3, procaspase-1, and IL-1βwere significantly induced by high glucose concentration and lipopolysaccharide in a dose-dependent and time-dependent manner in vitro. This induction by both high glucose and lipopolysaccharide was significantly inhibited by N-acetyl-L-cysteine. Our results firstly reveal that high glucose and lipopolysaccharide activate ROS/TXNIP/ NLRP3/IL-1βinflammasome signaling in glomerular mesangial cells, suggesting a mechanism by which inflammation may contribute to the development of diabetic nephropathy.

OBJECTIVE: To assess the effectiveness of clonazepam, in a fixed dose (2 mg/day), compared with placebo in the treatment of panic disorder patients. METHOD: 24 panic disorder patients with agoraphobia were randomly selected. The diagnosis was obtained using the structured clinical interview for DSM-IV . All twenty-four subjects were randomly assigned to either treatment with clonazepam (2 mg/day) or placebo, during 6 weeks. Efficacy assessments included: change from baseline in the number of panic attacks; CGI scores for panic disorder; Hamilton rating scale for anxiety; and panic associated symptoms scale. RESULTS: At the therapeutic endpoint, only one of 9 placebo patients (11.1%) were free of panic attacks, compared with 8 of 13 (61.5%) clonazepam patients (Fisher exact test; p=0,031). CONCLUSION: the results provide evidence for the efficacy of clonazepam in panic disorder patients.

Background: COVID-19 is a newly emerging infectious disease which is found to be caused by SARS-2. COVID-19 pandemic has spread worldwide causing a rapidly increasing number of mental disorders cases, primarily anxiety disorder. Since majority of panic disorder patients are present with great anxiety in response to their physical or respiratory symptoms, support and encouragement from psychiatrist or therapist are fundamental to alleviate the severity of the symptoms. Case Report: We reported a case of COVID-19 induced panic disorder in a woman, 52 years old, batak tribe who started to experience multiple panic attacks since one of her family members was confirmed to be Covid-10 positive. Conclusion: In general, panic disorder is a common diagnosis, but this case appeared to be interesting as it is induced by COVID-19 pandemic. As in this case, the individual who experienced multiple panic attack is not even a COVID-19 patient but has one of her family member affected by the virus. A wide body of evidence has shown that this pandemic massively contributes to worsening of psychosocial burden in nationwide.

Introduction. A cognitive model of aetiology of panic disorder assumes that people who experience frequent panic attacks have tendencies to catastrophically interpret normal and benign somatic sensations - as signs of serious illness. This arise the question: is this cognition specific for patients with panic disorder and in what intensity it is present in patients with serious somatic illness and in healthy subjects. Objective. The aim of the study was to ascertain the differences in the frequency and intensity of 'catastrophic' cognitions related to body sensations, and to ascertain the differences in the frequency and intensity of anxiety caused by different body sensations all related to three groups of subjects: a sample of patients with panic disorder, a sample of patients with history of myocardial infarction and a sample of healthy control subjects from general population. Methods. Three samples are observed in the study: A) 53 patients with the diagnosis of panic disorder; B) 25 patients with history of myocardial infarction; and C) 47 healthy controls from general population. The catastrophic cognitions were assessed by the Agoraphobic Cognitions Questionnaire (ACQ) and the Body Sensations Questionnaire (BSQ). These questionnaires assess the catastrophic thoughts associated with panic and agoraphobia (ACQ) and the fear of body sensations (BSQ). All study subjects answered questionnaires items, and the scores of the answers were compared among the groups. Results. The results of the study suggest that: 1) There is no statistical difference in the tendency to catastrophically interpret body sensations and therefore to induce anxiety in the samples of healthy general population and patients with history of myocardial infarction; 2) The patients with panic disorder have a statistically significantly more intensive tendency to catastrophically interpret benign somatic symptoms and therefore to induce a high level of anxiety in comparison to the sample of patients with the history of serious somatic illness (myocardial infarction) and the sample of healthy general population. Conclusion. The tendency to catastrophically interpret benign somatic symptoms and therefore to induce a high level of anxiety in patients with panic disorder, confirms the cognitive aetiology model of panic disorder and suggests that it should be the focus of prophylactic and therapeutic management of patients with panic disorder.
