ABSTRACT
OBJECTIVE: Limited research has directly investigated whether and how placebo effects can be harnessed for the treatment of functional neurological disorder (FND), despite a long-standing and controversial history of interest in this area. METHODS: A small exploratory study was conducted with adults with a cognitive subtype of FND recruited from a single cognitive neurology center in the United States. Participants were given the expectation of receiving cranial stimulation that could benefit their memory symptoms; however, the intervention was sham transcranial magnetic stimulation (placebo). Outcomes included measures of short-term memory testing, subjective memory rating, and state anxiety before and after stimulation. After the study, the true objective and rationale for investigating placebo effects were explained in a scripted debriefing session. Acceptability of the study design and qualitative feedback were collected. Institutional ethics approval and signed consent were obtained. RESULTS: Three patients (female, N=2; male, N=1; average age=57 years) were recruited. Outcome data were analyzed descriptively at the patient level. Trends of improvement in subjective memory rating, but not objective cognitive test scores, and decreases in state anxiety were observed. After the debriefing session, all patients found the study design to be acceptable (ratings of 70%, 90%, and 100%), and two of the three patients believed that withholding mechanistic information about the intervention was needed to leverage placebo effects as treatment. CONCLUSIONS: In the first study to prospectively investigate the feasibility of harnessing placebo effects for the treatment of FND, promising preliminary findings were obtained, and methods and resources for use in larger future studies are offered.

OBJECTIVE: Functional seizures are common among people with traumatic brain injury (TBI). Subjective cognitive concerns refer to a person's own perception of problems with cognitive functioning in everyday life. The authors investigated the presence and correlates of subjective cognitive concerns and the response to neurobehavioral therapy among adults with TBI and functional seizures (TBI+FS group). METHODS: In this observational study, participants in the TBI+FS group (N=47) completed a 12-session neurobehavioral therapy protocol for seizures, while participants in the comparison group (TBI without seizures) (N=50) received usual treatment. Subjective cognitive concerns, objective cognition, mental health, and quality of life were assessed before and after treatment. Data collection occurred from 2018 to 2022. RESULTS: Baseline subjective cognitive concerns were reported for 37 (79%) participants in the TBI+FS group and 20 (40%) participants in the comparison group. In a multivariable regression model in the TBI+FS group, baseline global mental health (ß=-0.97) and obsessive-compulsive symptoms (ß=-1.01) were associated with subjective cognitive concerns at baseline. The TBI+FS group had fewer subjective cognitive concerns after treatment (η2=0.09), whereas the TBI comparison group showed a nonsignificant increase in subjective cognitive concerns. CONCLUSIONS: Subjective cognitive concerns are common among people with TBI and functional seizures and may be related to general mental health and obsessive-compulsive symptoms. Evidence-based neurobehavioral therapy for functional seizures is a reasonable treatment option to address such concerns in this population, although additional studies in culturally diverse samples are needed. In addition, people with functional seizures would likely benefit from rehabilitation specifically targeted toward cognitive functioning.

Neuroscience-based patient education has become an evidence-based strategy for enhancing chronic pain treatment. Advances in understanding the neuroscience of functional neurological disorder (FND) may allow similar approaches to be developed and disseminated to clinicians, given the public health need for greater provider awareness and expertise around the condition. Accordingly, the authors developed an online video module for clinicians that delivers neuroscience-based psychoeducation for FND and assessed whether the intervention would be associated with changes in clinicians' perception of FND patients and knowledge about the condition. The online intervention consisted of a 20-minute video module, including an 8-minute scripted role-play that modeled neuroscience-informed diagnosis delivery. Pre- and postintervention questionnaires were embedded into the online module and included a self-assessment of FND-related perceptions and knowledge and a multiple-choice assessment of retention of the neuroscience-based content. Wilcoxon signed-rank tests and McNemar's tests were used for statistical analyses. Of the 103 individuals who submitted surveys, 40 participants provided a complete data set from before and after the intervention. Following the intervention, self-assessment items showed respondents had significantly greater comfort with diagnosis delivery and treatment options and decreased negative perception of FND patients. The percentage of correct responses on a multiple-choice assessment regarding the functional neuroanatomy of FND was significantly increased. In summary, the online neuroscience-based educational intervention was effective for increasing clinician knowledge about FND and comfort with diagnosis delivery and treatment options. Implementing web-based formats may be a viable and cost-effective approach to disseminating knowledge and basic clinical skills in the care of patients with FND.

PURPOSE OF REVIEW: We review recent evidence on Illness Anxiety Disorder (IAD), including risk factors and precipitants, diagnostic classification, clinical characteristics of the disorder, and assessment and treatment in both children and adults. RECENT FINDINGS: IAD places a substantial burden on both individuals and society. Despite its impact, understanding of the disorder is lacking and debates remain about whether IAD should be classified as an anxiety disorder and whether it is distinct from Somatic Symptom Disorder. Cognitive behavioural therapy (CBT) is an effective treatment for IAD and there are multiple validated measures of health anxiety available. However, research on health anxiety in children and youth is limited. IAD is chronic, and debilitating, but when identified, it can be effectively treated with CBT. Research using DSM-5 IAD criteria is lacking, and more research is needed to better understand the disorder, particularly in children and youth.

As clinicians involved in the care of patients with disorders of gut-brain interaction (DGBIs), we-and many colleagues-have the impression that social media are adversely shaping the nature, presentation, and ability to manage these disorders, especially at the severe end of the DGBI clinical spectrum. We turned to the research literature to see if these clinical impressions were corroborated but found it virtually nonexistent. Social media have rapidly become a ubiquitous, pervasive part of the lives of most people on the planet. Although they bring many benefits, they are also replete with health misinformation, reinforcement of abnormal sick-role behavior, and undermining of the legitimacy of psychological care. We first set out four reasons for concern about social media and DGBIs, particularly severe DGBIs. These reasons stem from phenomena described in medical fields outside DGBIs, but there is no reason to think DGBIs should be exempt from such phenomena. We then present the results of a literature search, which yielded only eight disparate recent empirical studies. We review these studies, which, although not uninformative, reveal a field in its infancy. We set out implications, most urgently multidisciplinary research directly addressing the role of social media and evaluation of interventions to mitigate its ill effects. Gastroenterological clinicians involved in DGBI care and research need to collaborate with experts in social media research, which is a very rapidly evolving, specialized field. Although knowledge is at an early stage, there are implications for specialist practice, education and training, and DGBI service delivery.
ABSTRACT
BACKGROUND: Functional somatic symptoms (FFS) and bodily distress disorders are highly prevalent across all medical settings. Services for these patients are dispersed across the health care system with minimal conceptual and operational integration, and patients do not currently access therapeutic offers in significant numbers due to a mismatch between their and professionals' understanding of the nature of the symptoms. New service models are urgently needed to address patients' needs and to align with advances in aetiological evidence and diagnostic classification systems to overcome the body-mind dichotomy. METHOD: A panel of clinical experts from different clinical services involved in providing aspects of health care for patients with functional symptoms reviewed the current care provision. This review and the results from a focus group exploration of patients with lived experience of functional symptoms were explored by the multidisciplinary expert group, and the conclusions are summarised as recommendations for best practice. RESULTS: The mapping exercise and multidisciplinary expert consultation revealed five themes for service improvement and pathway development: time/access, communication, barrier-free care, choice and governance. Service users identified four meta-themes for best practice recommendations: focus on healthcare professional communication and listening skills as well as professional attributes and knowledge base to help patients being both believed and understood in order to accept their condition; systemic and care pathway issues such as stronger emphasis on primary care as the first point of contact for patients, resources to reduce the length of the patient journey from initial assessment to diagnosis and treatment. CONCLUSION: We propose a novel, integrated care pathway for patients with 'functional somatic disorder', which delivers care according to and working with patients' explanatory beliefs. The therapeutic model should operate based upon an understanding of the embodied nature of patient's complaints and provide flexible access points to the care pathway.

INTRODUCTION: To test the hypothesis, whether HADS/SOMS is practical in a spine surgery consultation setting and that patients with CLBP, but a high-risk of psychic comorbidities using above screenings will not improve after minimal-invasive spine interventions (MIS). METHODS: n = 150 completed HADS and SOMS prior to the acquisition of history and examination. Primary outcome was improvement by numeric rating scale (NRS), Pain disability index (PDI) and oswestry disability index (ODI) at baseline and 6 months after intervention. In case of sciatica due to disc herniation epidural neurolysis, for facet or SI-joint-syndrome, radiofrequency and for discogenic pain intradiscal electrothermal therapy (IDET) was performed. RESULTS: 6 months after interventions, pat. with a high-risk of anxiety or depression showed no clinically important improvements in NRS, PDI and ODI, whereas in the low-risk group all 3 parameters were significantly reduced. We found a statistically significant difference in the improvement of NRS (p < 0·05), PDI (p < 0·001), ODI (p < 0·001) between high- and low-risk HADS-anxiety and depression groups and in the improvement of NRS and PDI (p < 0·05) between high- and low-risk SOMS-2-subgroups. CONCLUSIONS: In this group of CLBP patients, the easy-to-administer HADS/SOMS reliably predicted outcome after MIS due to the detection of somatoform comorbidities. Thus, 30 out of 150 patients were invasively treated without improvement. This is alarming not only because of unnecessary MIS being performed on these individuals, but also because it represents an inefficient allocation of increasingly limited healthcare funds. LEVEL OF EVIDENCE: II.

Amidst broad changes to the somatic disorder diagnoses, DSM-IV pain disorder was absorbed into DSM-5's somatic symptom disorder (SSD) as a specifier. However, clinical research testing of its use for the chronic pain population has been limited and its utility remains inconclusive. Using the exemplar of fibromyalgia, this article evaluates the validity, reliability, clinical utility, and acceptability of the SSD pain specifier. The diagnosis appears to have moderate validity but low specificity for the fibromyalgia population. The pain specifier has neither undergone sufficient field testing nor been evaluated for use by medical providers, with available data suggesting low reliability. Further research is needed to establish clinical utility via assessment of differential treatment outcomes. Concerns about social, legal, and economic consequences of classifying pain patients with a mental health diagnosis are outstanding. The current SSD criteria should be used with caution among the fibromyalgia patient population until its application for chronic pain has been further researched.

Background and objective: Cognitive-behavioral therapy (CBT) for somatoform disorders (SFDs) is understudied in China. Western findings may not be applicable to Chinese culture. This preliminary study evaluated the efficacy of CBT for patients in China, relative to treatment-as-usual (TAU). Methods: Seventy patients with SFDs randomly received either combined CBT and TAU (CBT + TAU), or TAU alone between January 2018 to May 2019. The CBT + TAU group received 12 weekly individual 50-minute CBT sessions. Participants were blindly assessed at 4 timepoints (baseline, week 6, end of treatment: week 12; 12 weeks post-treatment: week 24) using the following outcome measures: SQSS (Self-screening Questionnaire for Somatic Symptoms); PHQ-15 (Patient-Health-Questionnaire-15) and the WI (Whiteley Index); GAD-7 (General Anxiety Disorder-7); HAMD-17 (Hamilton Depression Rating Scale-17); Family Burden Interview Schedule (FBIS); Sheehan Disability Scale (SDS); and the Short Form of Quality-of-Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q-SF). The primary endpoint was the difference between the SQSS total score at week 24 and the baseline. A mixed model for repeated measures was used to analyze inter- and intra-group changes from the baseline. Results: At week 24, The least-squares mean (LSM) change of the total score on the SQSS was -18.87 points and -9.69 points, respectively in the CBT + TAU group and in the TAU group (LSM difference, -9.18 points; 95% confidence interval, -15.72 to -2.64; P = 0.0068). At week 24, the LSM changes from baseline in the WI, HAMD, PHQ15, FBIS and SDS total scores were significantly different between the two groups, however, there was no significant difference in the Q-LES-Q-SF. The SQSS of group effect sizes were 0.63 at 24 weeks. The dropout rates of the CBT + TAU and TAU groups were comparable (22.9% and 19.3%). Conclusions: These preliminary findings suggest that CBT may be helpful for improving the symptoms of patients with SFDs in China.
ABSTRACT
OBJECTIVE: Functional neurological disorder (FND) is frequently encountered in clinical practice but commonly misdiagnosed, which might lead to higher direct costs for the health care system. The investigators analyzed the direct costs associated with the diagnosis of FND compared with costs associated with other neurological conditions and explored possible cost trends related to the clinical and demographic features of FND. METHODS: Consecutive patients attending a general neurology clinic were recruited and underwent a structured assessment aimed to collect information pertaining to their demographic and clinical characteristics, as well as data regarding their prior diagnostic processes (e.g., the number of consulted specialists, number and type of investigations, emergency department visits, etc.). The costs were hence calculated and compared between the study groups. RESULTS: A total of 155 consecutive patients were recruited; of these, 18.6% had FND, 55.84% had one or more other neurological disorder (OND), and 27.10% presented with comorbid FND and OND. The total prediagnostic costs (in euros []) were higher in the FND group compared with the OND group (median=289, interquartile range [IQR] 385 vs. median=98, IQR 216; Mann-Whitney U=879.5, p=0.04). There was a higher diagnostic delay in the FND group compared with the OND group (median=48 months, IQR 60 months vs. median=12 months, IQR 6 months; Mann-Whitney U=162.00, p<0.01). Diagnostic delay significantly correlated with the total costs in the entire study sample (Spearman's ρ=0.25, p=0.003) but more strongly in the FND group (Spearman's ρ=0.81, p<0.001). In the FND group, higher numbers of investigations and costs were associated with the presence of a physiological or psychological trigger and multiple symptoms. CONCLUSIONS: Delayed diagnosis of FND significantly affects health care system costs, and raising awareness about FND to improve the diagnostic process and outcomes is necessary.

Objective: Functional neurological disorder (FND) causes a high burden of disability and distress. Although it is a common disorder, there is a pressing need for improved access to evidence-based treatments. With difficulties in finding effective treatment, some people with FND may seek alternative means of symptom relief, such as legal and illicit psychoactive substances, although the prevalence and nature of such self-management strategies are currently unclear. Additionally, psychoactive substances may represent novel treatment research opportunities, particularly for those with suboptimal improvement. The investigators examined the use of self-management techniques, as well as perspectives on novel therapies, in this patient population. Methods: An online survey was created to assess self-management strategies and views on novel treatments for FND, including psychedelic therapy. The survey was accessible for 1 month, and respondents were recruited internationally through social media and patient groups. A total of 1,048 respondents from 16 countries completed the survey. Results: Almost half (46%) of 980 respondents reported having tried legal psychoactive substances for the management of their FND symptoms and, on average, nicotine, alcohol, and cannabidiol were reported as modestly effective. Additionally, 15% of respondents reported having used illicit substances, mostly cannabis, to manage FND, with the majority reporting moderate effectiveness and experiencing no or minimal physical (90%) and psychological (95%) sequelae. Many respondents (46%) reported that they would be willing to try medically supervised psychedelic therapy (with 19% of respondents ambivalent) if it were found to be safe and effective. Conclusions: Many people with FND seek alternative means of symptom management outside usual medical care, including legal and illicit psychoactive substances. Further research exploring novel treatment options, such as psychedelics, in FND may be warranted.

PURPOSE: Enhanced responsiveness to external triggers is thought to reflect hypersensitivity of the cough reflex. It may involve an enhanced sensitivity of the afferent nerves in the airways and/or an abnormal processing of the afferent information by the central nervous system (CNS). The CNS processing of cough has been shown to involve the same regions as those in symptom amplification, a phenomenon that often manifests as multiple symptoms. The main purpose of the present study was to define whether the presence of several cough triggers is associated with multiple symptoms. METHODS: 2131 subjects with current cough responding to two email surveys filled in a comprehensive questionnaire about social background, lifestyle, general health, doctors' diagnoses and visits, symptoms, and medication. Multiple symptoms was defined as three or more non-respiratory, non-mental symptoms. RESULTS: A carefully controlled multiple regression analysis revealed that the number of cough triggers was the only cough characteristic associating with multiple non-respiratory, non-mental symptoms [aOR 1.15 (1.12-1.19) per one trigger, p < 0.001]. Among the 268 subjects with current cough both in the first survey and in the follow-up survey 12 months later, the repeatability of the trigger sum was good with an intraclass correlation coefficient of 0.80 (0.75-0.84). CONCLUSION: The association between the number of the cough triggers and multiple symptoms suggests that the CNS component of cough hypersensitivity may be a manifestation of non-specific alteration in the CNS interpretation of various body sensations. The number of cough triggers is a repeatable measure of cough sensitivity.

BACKGROUND: School closures and social distancing may have affected mental health among preadolescent and adolescent children, who are in a social developmental stage. Rates of anxiety, depression, and stress have been reported to have increased during the COVID-19 pandemic among teenagers worldwide. However, most studies have measured children's mental health in cross-sectional studies or short-term comparisons before and after lockdowns and school closures, and few studies have tracked the long-term effects on mental health among children and adolescents, despite the pandemic lasting more than 2 years. METHODS: An interrupted time-series analysis was performed for longitudinal changes in the monthly number of new mental disorders (eating disorders, schizophrenia, mood disorders, and somatoform disorders). Using a nationwide multicenter electronic health records database in Japan, we analyzed data of patients aged 9 to 18 years from 45 facilities that provided complete data throughout the study period. The study period covered January 2017 to May 2021, defining a national school closure as an intervention event. We modeled the monthly new diagnoses of each mental disorder using a segmented Poisson regression model. RESULTS: The number of new diagnoses throughout the study period was 362 for eating disorders, 1104 for schizophrenia, 926 for mood disorders, and 1836 for somatoform disorders. The slope of the regression line in monthly number of new diagnoses increased in the post-pandemic period for all targeted mental disorders (change in slope for eating disorders 1.05, 95% confidence interval [CI] 1.00-1.11; schizophrenia 1.04, 95% CI 1.01-1.07; mood disorders 1.04, 95% CI 1.01-1.07; and somatoform disorders 1.04 95% CI 1.02-1.07). The number of new diagnoses for schizophrenia and mood disorders increased early after school closure; while eating disorders showed an increasing trend several months later. Somatoform disorders showed a decreasing trend followed by an increasing trend. Time trends by sex and age also differed for each mental disorder. CONCLUSIONS: In the post-pandemic period, the number of new cases increased over time for eating disorders, schizophrenia, mood disorders, and somatoform disorders. The timing of increase and trends by sex and age differed for each mental disorder.

BACKGROUND: In China, patients with somatoform disorders (SFD) often seek medical treatment repeatedly in outpatient clinics of general hospitals, which increases unreasonable medical expenses. It is imperative to provide early screening to these patients and specialized treatment to reduce the unnecessary cost. This study aimed to screen patients with SFD in general hospitals using a new Chinese questionnaire and explore the characteristics and economic burden of these patients. METHODS: Patients (n = 1497) from the outpatient department of neurology, cardiology and gastroenterology of three large general hospitals were included. Participants were screened using a newly developed questionnaire, the Self-screening Questionnaire for Somatic Symptoms (SQSS), to identify the patients with SFD (total SQSS score ≥ 29 points). We compared the demographics and clinical information of patients with and without SFD. Logistic regression was used to explore potential factors related to medical expenses, visits to doctors and sick leave days taken. RESULTS: The frequency of detection of patients with SFD was 17.03%. There were significant differences in employment, doctor visits, symptom duration, medical expenses, sick leave days, PHQ-15 scores, and PHQ-9 scores between patients with SFD and without SFD. General nonspecific somatic symptoms were frequently present in patients with SFD. Several potential factors were associated with higher medical expenses, repeated doctor visits, and sick leave days taken in the regression analysis. CONCLUSION: The findings indicate that patients with SFD are common in general hospitals, and their direct and indirect economic burden is higher than that of non-SFD patients, which indicates that more screening effort should be made to this group to early identify their problems. Certain characteristics were identified among patients with SFD and several factors were associated with negative consequences of SFD, all of which might be prevented by developing a preventive intervention program to reduce the economic burden of the patients.
ABSTRACT
OBJECTIVES: Somatic symptom disorder (SSD) is a diagnostic classification to describe the occurrence of physical symptoms without organic cause. This study aimed to identify prevalence rates and associated characteristics of SSD among adults in primary care settings. METHODS: This cross-sectional study took place between July 2020 and March 2021 and included a random selection of 3383 Omani adults attending 12 primary healthcare centres in Muscat Governorate. Screening was conducted using an Arabic version of the Somatic Symptom Scale-8 (SSS-8). RESULTS: A total of 2000 adults participated in the study (response rate: 67.3%), of which most were female (71.7%) and under 50 years old (86.2%). Based on their SSS-8 scores, 602 participants (17.8%) had SSD, resulting in an overall prevalence estimate of 30.1% (95% confidence interval: 28.13-32.15). Significant associations were observed between SSD and age (p = 0.002), gender (p < 0.001), marital status (p = 0.030) and chronic comorbidities (p = 0.001). In addition, adjusted odds ratio estimates revealed SSD to be significantly associated with gender (p < 0.001), education level (p < 0.001) and chronic comorbidities (p = 0.001). CONCLUSION: The estimated prevalence of SSD in primary care settings is high compared to reports from elsewhere in the Gulf region. There is an urgent need to enhance the diagnosis of SSD at the primary care level in order to reduce healthcare service overutilisation and patient dissatisfaction. Moreover, healthcare practitioners should be aware of the effect of age, gender, educational status and chronic comorbidities on somatic symptoms.

BACKGROUND: There is limited knowledge of the possible side-effects of clear aligners on jaw function. OBJECTIVES: To determine the short-term effect of passive clear aligners (PCAs) on masticatory muscle activity (MMA), occlusal discomfort (OD) and temporomandibular disorder (TMD) symptoms in adults with different levels of self-reported oral parafunction. MATERIALS AND METHODS: Participants were screened for oral parafunctional behaviours using the oral behavioural checklist. Respondents in ≥85th and ≤15th percentiles were invited to participate and allocated to a high (HPF: N = 15) or low (lower parafunction [LPF]: N = 16) parafunction group. Participants underwent a TMD clinical examination; somatisation and somatosensory amplification were assessed by questionnaires; OD and stress were assessed by visual analogue scales. While wearing PCAs, awake-time MMA was assessed three times over 9 days using a wearable electromyography device, along with OD, stress and TMD symptoms. RESULTS: The wearing of PCAs was associated with a significant decrease in mean contraction episode amplitude in both groups (p = 0.003). OD levels increased and remained raised in all participants after insertion of the PCAs (p < 0.001), more so in the HPF group (p = 0.048). The HPF group had higher somatisation scores (p = 0.006) and reported more TMD symptoms at all time points (p ≤ 0.004). No significant changes in stress or TMD symptoms were found in either group during the study period. CONCLUSIONS: PCAs were associated with a decrease in MMA in all participants. HPF individuals had greater somatisation and reported greater discomfort when wearing PCAs than LPF individuals.

BACKGROUND: In 2013, the diagnosis of somatic symptom disorder (SSD) was introduced into the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This review aims to comprehensively synthesize contemporary evidence related to SSD. METHODS: A scoping review was conducted using PubMed, PsycINFO, and Cochrane Library. The main inclusion criteria were SSD and publication in the English language between 01/2009 and 05/2020. Systematic search terms also included subheadings for the DSM-5 text sections; i.e., diagnostic features, prevalence, development and course, risk and prognostic factors, culture, gender, suicide risk, functional consequences, differential diagnosis, and comorbidity. RESULTS: Eight hundred and eighty-two articles were identified, of which 59 full texts were included for analysis. Empirical evidence supports the reliability, validity, and clinical utility of SSD diagnostic criteria, but the further specification of the psychological SSD B-criteria criteria seems necessary. General population studies using self-report questionnaires reported mean frequencies for SSD of 12.9% [95% confidence interval (CI) 12.5-13.3%], while prevalence studies based on criterion standard interviews are lacking. SSD was associated with increased functional impairment, decreased quality of life, and high comorbidity with anxiety and depressive disorders. Relevant research gaps remain regarding developmental aspects, risk and prognostic factors, suicide risk as well as culture- and gender-associated issues. CONCLUSIONS: Strengths of the SSD diagnosis are its good reliability, validity, and clinical utility, which substantially improved on its predecessors. SSD characterizes a specific patient population that is significantly impaired both physically and psychologically. However, substantial research gaps exist, e.g., regarding SSD prevalence assessed with criterion standard diagnostic interviews.

BACKGROUND: The 2019 coronavirus disease (COVID-19) pandemic has had a profound impact on the mental health of people worldwide. This study examined dysfunctional coronavirus anxiety in nonpsychotic psychiatric outpatients during the pandemic using the coronavirus anxiety scale (CAS) and examined the relationship between coronavirus anxiety and clinical symptoms using network analysis. METHODS: In this cross-sectional study, 192 patients who first visited the psychiatric outpatient clinic of Severance Hospital during the COVID-19 pandemic with chief complaints of depressed mood, anxiety, somatic symptoms, or insomnia were included. We compared the clinical characteristics of patients with and without dysfunctional coronavirus anxiety. Network analysis was conducted to estimate the network of coronavirus anxiety and depressive, anxious, and hypochondriacal psychopathology. RESULTS: The results showed that 7.8% of patients exhibited dysfunctional coronavirus anxiety (CAS ≥ 5). Patients with dysfunctional coronavirus anxiety showed higher levels of health worry, somatic preoccupation, and subjective anxiety compared to patients without dysfunctional coronavirus anxiety. In the network analysis, the health worry node (Item 6 of the WI) showed the greatest number of connections with coronavirus anxiety nodes. CONCLUSIONS: These findings suggest that health worry may be an important bridge symptom that connects coronavirus anxiety and other clinical psychopathology. Patients with elevated health worries should be carefully monitored during the COVID-19 pandemic for exacerbation of previous symptoms and COVID-19-related psychopathology. Understanding the psychological factors in the face of the pandemic and their relationships with clinical psychiatric symptoms would help people prevent and overcome mental health problems during the pandemic.

BACKGROUND: Emotional disorders are common, and they have become more prevalent since the COVID-19 pandemic. Due to a high attendance burden at the specialized level, most emotional disorders in Spain are treated in primary care, where they are usually misdiagnosed and treated using psychotropic drugs. This contributes to perpetuate their illness and increase health care costs. Following the IAPT programme and the transdiagnostic approach, the PsicAP project developed a brief group transdiagnostic cognitive-behavioural therapy (tCBT) as a cost-effective alternative. However, it is not suitable for everyone; in some cases, one-on-one sessions may be more effective. The objective of the present study is to compare, in cost-benefit terms, group and individual tCBT with the treatment usually administered in Spanish primary care (TAU). METHODS: A randomized, controlled, multicentre, and single-blinded trial will be performed. Adults with mild to moderate emotional disorders will be recruited and placed in one of three arms: group tCBT, individual tCBT, or TAU. Medical data and outcomes regarding emotional symptoms, disability, quality of life, and emotion regulation biases will be collected at baseline, immediately after treatment, and 6 and 12 months later. The data will be used to calculate incremental cost-effectiveness and cost-utility ratios. DISCUSSION: This trial aims to contribute to clinical practice research. The involvement of psychologists in primary care and the implementation of a stepped-care model for mental disorders are recommended. Group therapy and a transdiagnostic approach may help optimize health system resources and unblock waiting lists so that people can spend less time experiencing mental health problems. TRIAL REGISTRATION: ClinicalTrials.gov: NCT04847310; Protocols.io: bx2npqde. (April 19, 2021).

INTRODUCTION: Chest pain, palpitations, and syncope are among the most common referrals to paediatric cardiology. These symptoms generally have a non-cardiac aetiology in children and adolescents. The aim of this study was to investigate the rate of common psychiatric disorders in children and adolescents referred to the paediatric cardiology clinic with chest pain, palpitations, and syncope and the relationship between cardiological symptoms and psychiatric disorders. METHODS: Children and adolescents aged 8-16 years who presented at the paediatric cardiology clinic with primary complaints of chest pain, palpitation, or syncope were included in the study. After a detailed cardiology examination, psychiatric disorders were assessed using the DSM IV-TR diagnostic criteria and a semi-structured interview scale (KSADS-PL). The Child Depression Inventory and Spielberger's State-Trait Anxiety Inventory for Children were also applied to assess the severity of anxiety and depression. RESULTS: The study participants comprised 73 (68.90%) girls and 33 (31.10%) boys with a mean age of 12.5 ± 2.4 years. Psychiatric disorders were determined in a total of 48 (45.3%) participants; 24 (38.7%) in the chest pain group, 12 (48.0%) in the palpitation group, and 12 (63.2%) in the syncope group. Cardiological disease was detected in 17% of the cases, and the total frequencies of psychiatric disorders (p = 0.045) were higher in patients with cardiological disease. CONCLUSION: It is clinically important to know that the frequency of psychiatric disorders is high in patients presenting at paediatric cardiology with chest pain, palpitations, and syncope. Physicians should be aware of patients' psychiatric problems and take a biopsychosocial approach in the evaluation of somatic symptoms.
