Psychological distress and uterine fibroids: a bidirectional two-sample mendelian randomization study.

BACKGROUND: Observational data indicates a connection between emotional discomfort, such as anxiety and depression, and uterine fibroids (UFs). However, additional investigation is required to establish the causal relationship between them. Hence, we assessed the reciprocal causality between four psychological disorders and UFs utilizing two-sample Mendelian randomization (MR). METHODS: To evaluate the causal relationship between four types of psychological distress (depressive symptoms, severe depression, anxiety or panic attacks, mood swings) and UFs, bidirectional two-sample MR was employed, utilizing single nucleotide polymorphisms (SNPs) associated with these conditions. Both univariate MR (UVMR) and multivariate MR (MVMR) primarily applied inverse variance weighted (IVW) as the method for estimating potential causal effects. Complementary approaches such as MR Egger, weighted median, simple mode, and weighted mode were utilized to validate the findings. To assess the robustness of our MR results, we conducted sensitivity analyses using Cochran's Q-test and the MR Egger intercept test. RESULTS: The results of our UVMR analysis suggest that genetic predispositions to depressive symptoms (Odds Ratio [OR] = 1.563, 95% Confidence Interval [CI] = 1.209-2.021, P = 0.001) and major depressive disorder (MDD) (OR = 1.176, 95% CI = 1.044-1.324, P = 0.007) are associated with an increased risk of UFs. Moreover, the IVW model showed a nominally significant positive correlation between mood swings (OR: 1.578; 95% CI: 1.062-2.345; P = 0.024) and UFs risk. However, our analysis did not establish a causal relationship between UFs and the four types of psychological distress. Even after adjusting for confounders like body mass index (BMI), smoking, alcohol consumption, and number of live births in the MVMR, the causal link between MDD and UFs remained significant (OR = 1.217, 95% CI = 1.039-1.425, P = 0.015). CONCLUSIONS: Our study presents evidence supporting the causal relationship between genetic susceptibility to MDD and the incidence of UFs. These findings highlight the significance of addressing psychological health issues, particularly depression, in both the prevention and treatment of UFs.

The multi-generational familial aggregation of interstitial cystitis, other chronic nociplastic pain disorders, depression, and panic disorder.

BACKGROUND: Interstitial cystitis/painful bladder syndrome (IC) is a chronic pelvic pain condition which has high comorbidity with other nociplastic, or unexplained, pain disorders [e.g. fibromyalgia (FM), irritable bowel syndrome (IBS), and myalgic encephalomyelitis/chronic fatigue (ME/CFS)] and some psychiatric conditions [major depressive disorder (MDD) and panic disorder (PD)]. Here we investigated the shared familiality of IC and these other nociplastic and psychiatric conditions. METHODS: Subjects were identified in the Utah Population Database, which links genealogy data back to the 1800s to medical record diagnosis billing code data back to 1995. We computed the relative risk of each of these disorders among first (FDR), second (SDR), and third-degree relatives (TDR) of six proband groups: IC, FM, IBS, ME/CFS, PD, and MDD. Given the known familial aggregation of each of these disorders, we conducted our analyses to test for heritable interrelationships using proband subgroups whose members did not have the diagnosis assessed in their relatives. RESULTS: We observed strong evidence for heritable interrelationships among all six disorders. Most analyses indicated significantly increased risk for each of the six disorders in FDR, SDR, and TDR of all or most proband groups. Out of 30 possible bidirectional disorder interrelationships, 26 were significant among FDR, 23 were significant among SDR, and 7 were significant among TDR. Clustering was observed in both close and distant relatives. CONCLUSIONS: Our results support a common, heritable component to IC and other nociplastic and psychiatric conditions.

Onset and temporal sequencing patterns of comorbidity between lifetime major depression, panic disorder and fibromyalgia.

OBJECTIVES: Fibromyalgia (FM) is a syndrome of unknown aetiology characterised by chronic widespread musculoskeletal pain and associated with high rates of psychiatric comorbidities, mainly mood and anxiety disorders.This study aims to determine the age at onset (AAO) and temporal sequencing patterns of FM and its frequent and distinguishable psychiatric comorbidities, the major depressive episode/s (MDE), and panic disorder (PD). METHODS: Diagnosis of MDE and PD were assigned using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders fourth edition (DSM-IV). The AAO of FM, MDE, and PD was defined using the event history calendar. All patients completed a sociodemographic data form, self-report questionnaires measuring FM-related symptoms and function, and the Childhood Trauma Questionnaire-28 (CTQ-28). RESULTS: 98 (83%) of the 118 recruited patients with FM had at least one psychiatric comorbidity. Two main temporal patterns were identified among the 83 patients (70.3 %) who could reliably report the age at onset of FM and psychiatric comorbidities. In the concurrent comorbidity pattern (CCP), MDE and/or PD co-occurred with the onset of FM. In the sequential pattern (SP), the patients first developed PD, then MDE, and finally FM. FM patients with SP are overweight and younger than those with a CCP (FM concurrent with MDE and PD) and reported more childhood adversities, mainly sexual abuse. AAO of psychiatric comorbidities significantly differed between the two patterns. CONCLUSIONS: The presence of different temporal comorbidity patterns may suggest prevention/early treatment interventions, especially in patients with childhood adversities and early-onset PD.

Asthma and early smoking associated with high risk of panic disorder in adolescents and young adults.

PURPOSE: Studies have reported a strong link between asthma and panic disorder. We conducted a 17-year community-based large cohort study to examine the relationship between asthma, early smoking initiation, and panic disorder during adolescence and early adulthood. METHODS: A total of 162,766 participants aged 11-16 years were categorized into asthma and nonasthma groups at baseline and compared within the observation period. Covariates during late childhood or adolescence included parental education, cigarette smoking by family members of participants, and participant's gender, age, alcohol consumption, smoking, and exercise habits. Data for urbanicity, prednisone use, allergic comorbidity, and Charlson comorbidity index were acquired from the National Health Insurance Research Database. The Cox proportional-hazards model was used to evaluate the association between asthma and panic disorder. RESULTS: Our findings revealed that asthma increased the risk of panic disorder after adjustment for key confounders in the Cox proportional hazard regression model (adjusted HR: 1.70, 95% CI 1.28-2.26). Hospitalizations or visits to the emergency department for asthma exhibited a dose-response effect on the panic disorder (adjusted HR: 2.07, 95% CI 1.30-3.29). Patients with asthma with onset before 20 years of age who smoked during late childhood or adolescence had the greatest risk for panic disorder (adjusted HR: 4.95, 95% CI 1.23-19.90). CONCLUSIONS: Patients newly diagnosed with asthma had a 1.7-times higher risk of developing panic disorder. Smoking during late childhood or adolescence increased the risk for developing the panic disorder in patients with asthma.

Ansiedad en pandemia: características epidemiológicas de los trastornos de ansiedad atendidos a través de telepsiquiatría en un hospital universitario / Anxiety in pandemic: epidemiological characteristics of anxiety disorders seen through telepsychiatry in a university hospital

RESUMEN Introducción: la pandemia de COVID-19 ha incrementado los casos de ansiedad y causado grandes modificaciones en la forma de prestar atención médica. Objetivo: describir las características epidemiológicas de los trastornos de ansiedad atendidos a través de telepsiquiatría en un Hospital Universitario. Metodología: estudio observacional, descriptivo, de corte transversal. Se realizó un muestreo no aleatorio intencional. Se utilizaron fichas electrónicas de pacientes tratados en el Servicio de Psiquiatría del Hospital de Clínicas, Paraguay, entre febrero y mayo de 2021. Se realizó estadística descriptiva de todas las variables. Se calcularon medidas de tendencia central y dispersión para las variables cuantitativas. Las cualitativas se resumieron en frecuencias y porcentajes. Resultados: el análisis incluyó 804 pacientes. El 71,5 % (575) de los pacientes procedían del ámbito rural. De todos los pacientes con diagnóstico de algún trastorno de ansiedad (20,49 % n = 165), el 69,1 % (114) correspondían a mujeres y el 49,7 % (82) presentaron trastorno de pánico (ansiedad paroxística episódica), 28,5 % (47) fueron diagnosticados con trastorno de ansiedad generalizada, y 21,8 % (36) tuvieron un trastorno de ansiedad no especificado. Conclusión: más del 20 % de los pacientes que consultaron a través de la modalidad de telepsiquiatría presentó algún cuadro del espectro ansioso. La presentación de casos se dio tanto en el ámbito rural como en el urbano y de preferencia en mujeres. El trastorno de pánico emergió como el trastorno de más alta frecuencia en la población accesible, representando casi la mitad de todos los casos de ansiedad diagnosticados.

ABSTRACT Introduction: the COVID-19 pandemic has increased anxiety cases and caused big modifications in the way medical care is provided. Objective: to describe the epidemiological characteristics of anxiety disorders treated through telepsychiatry in a University Hospital. Methodology: observational, descriptive, cross-sectional study. A non-random purposive sampling was performed. Electronic records of patients treated in the Psychiatry Department of the "Hospital de Clínicas", Paraguay, between February and May 2021 were used. Descriptive statistics were performed for all variables. Measures of central tendency and dispersion were calculated for quantitative variables. Qualitative variables were summarized in frequencies and percentages. Results: the analysis included 804 patients. Out of the patients, 71,5 % (575) were from rural areas. Out of all patients diagnosed with an anxiety disorder (20,49 % n = 165), 69,1 % (114) were female and 49,7 % (82) had panic disorder (episodic paroxysmal anxiety), 28,5 % (47) were diagnosed with generalized anxiety disorder, and 21,8 % (36) had an unspecified anxiety disorder. Conclusion: more than 20 % of the patients who consulted through the telepsychiatry modality presented with an anxiety spectrum disorder. Cases were presented in both rural and urban areas and preferably in females. Panic disorder emerged as the most frequent disorder in the accessible population, representing almost half of all diagnosed anxiety cases.

The course and clinical correlates of panic disorder during the postpartum period: a naturalistic observational study

Objective: To investigate the course of panic disorder and its demographic and clinical correlates during the postpartum period. Methods: Data were collected from 38 consecutive postpartum women diagnosed with panic disorder. Psychiatric assessments were carried out on the first day after delivery and at 6-8 weeks postpartum. During the first assessment, the Panic and Agoraphobia Scale (PAS), Hospital Anxiety and Depression Scale (HADS), Coping Orientation to Problems Experienced (COPE), Multidimensional Scale of Perceived Social Support (MSPSS), and Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) were administered to the participants. PAS was also administered at the second assessment. Results: The mean PAS score reduced significantly from baseline to the second assessment. Logistic regression analysis indicated that a shorter duration of panic disorder independently predicted a ≥ 50-point decrease in the severity of panic symptoms during the postpartum period. Conclusion: These findings suggest that patients with a short duration of illness may experience significant alleviation in the severity of panic symptoms during the postpartum period.

The spectrum of pediatric amplified musculoskeletal pain syndrome.

BACKGROUND: Children presenting with musculoskeletal pain to pediatric rheumatology clinics are very heterogeneous and on a continuum from those with localized pain to total body pain. Many report intermittent, rather than constant, pain. We examined clinical and psychological characteristics of these children at presentation and specifically those who fulfilled the criteria for fibromyalgia. METHODS: We performed a retrospective, cross-sectional cohort study of children under ≤18 years old presenting to the pediatric rheumatology pain clinic between January 2015 and July 2019 and enrolled in a patient registry. We included children diagnosed with amplified pain, excluding those fulfilling criteria for complex regional pain syndrome. Abstracted data included clinical characteristics, pain symptoms, functional disability inventory (FDI), widespread pain index, and symptom severity scale. RESULTS: We analyzed 636 subjects, predominantly non-Hispanic Caucasian females. Using median split method, 54% had diffuse pain (≥ 5 body regions involved), but, of these, only 58% met criteria for fibromyalgia. Subjects with diffuse pain, compared to those with localized pain had a longer duration of pain (24 vs 12 months, p < 0.01), reported greater pain intensity (6/10 vs 5/10, p < 0.001), greater mental health burden, and poorer function (FDI 25 vs 19, p < 0.0001). Subjects with limited pain more often reported a history of trigger event (34% vs 24%, p < 0.01) but not autonomic changes (14% vs 14%, p = 0.94). The presence of adverse childhood experiences did not differ among those with limited versus diffuse pain except for parental divorce (16% vs 23%, p = 0.03). Intermittent pain was reported in 117 children (18%) and, compared to subjects with constant pain, they reported less pain (0/10 vs 6/10) and were more functional (FDI 13 vs 25) (both p < 0.0001). CONCLUSIONS: There exists a wide spectrum of pain manifestations among children with amplified pain including limited or diffuse and constant or intermittent pain. Most children who presented to our clinic did not fulfill criteria for fibromyalgia but nonetheless had significant symptoms and disability. Studies focusing on fibromyalgia may miss the full extent of childhood amplified pain. Additionally, research limited to those meeting the fibromyalgia criteria likely underestimate the significant impact of amplified pain among the pediatric population.

Body Dissatisfaction and Mental Health Outcomes of Youth on Gender-Affirming Hormone Therapy.

OBJECTIVES: Our first aim was to examine baseline differences in body dissatisfaction, depression, and anxiety symptoms by gender, age, and Tanner (ie, pubertal) stage. Our second aim was to test for changes in youth symptoms over the first year of receiving gender-affirming hormone therapy. Our third aim was to examine potential differences in change over time by demographic and treatment characteristics. Youth experiences of suicidal ideation, suicide attempt, and nonsuicidal self-injury (NSSI) are also reported. METHODS: Participants (n = 148; ages 9-18 years; mean age 14.9 years) were receiving gender-affirming hormone therapy at a multidisciplinary program in Dallas, Texas (n = 25 puberty suppression only; n = 123 feminizing or masculinizing hormone therapy). Participants completed surveys assessing body dissatisfaction (Body Image Scale), depression (Quick Inventory of Depressive Symptoms), and anxiety (Screen for Child Anxiety Related Emotional Disorders) at initial presentation to the clinic and at follow-up. Clinicians completed the Quick Inventory of Depressive Symptoms and collected information on youth experiences of suicidal ideation, suicide attempt, and NSSI. RESULTS: Affirmed males reported greater depression and anxiety at baseline, but these differences were small (P < .01). Youth reported large improvements in body dissatisfaction (P < .001), small to moderate improvements in self-report of depressive symptoms (P < .001), and small improvements in total anxiety symptoms (P < .01). No demographic or treatment-related characteristics were associated with change over time. Lifetime and follow-up rates were 81% and 39% for suicidal ideation, 16% and 4% for suicide attempt, and 52% and 18% for NSSI, respectively. CONCLUSIONS: Results provide further evidence of the critical role of gender-affirming hormone therapy in reducing body dissatisfaction. Modest initial improvements in mental health were also evident.

Anxiety Disorders and Medical Comorbidity: Treatment Implications.

Anxiety disorders are debilitating psychological disorders characterized by a wide range of cognitive and somatic symptoms. Anxiety sufferers have a higher lifetime prevalence of various medical problems. Chronic medical conditions furthermore increase the likelihood of psychiatric disorders and overall dysfunction. Lifetime rates of cardiovascular, respiratory, gastrointestinal, and other medical problems are disproportionately high in anxiety and panic/fear sufferers. The heightened comorbidity is not surprising as many symptoms of anxiety and panic/fear mimic symptoms of medical conditions. Panic disorder specifically is strongly linked to medical conditions due to its salient somatic symptoms, such as dyspnea, dizziness, numbness, chest pain, and heart palpitations, all of which can signal danger and deterioration for chronic disease sufferers. This chapter identifies shared correlates of medical illness and anxiety disorders and evidence for misinterpretation of symptoms as medically relevant and offers an analysis of implications for treatment of both types of conditions. We will concentrate on medical conditions with high associations for anxiety and panic by aspects of symptomatology, specifically neurological disorders (fibromyalgia, epilepsy, cerebral palsy), diabetes, gastrointestinal illness (irritable bowel syndrome, gastroesophageal reflux disease), and cardiovascular and respiratory illnesses (asthma).

Assessment of sleep quality of patients with panic disorder and generalized anxiety disorder during remission: a case-control study

Abstract Background Sleep disorders are common in psychiatric diseases. Panic disorder (PD) and generalized anxiety disorder (GAD) are two major anxiety disorders that are associated with sleep disorders. Objective We hypothesized that poor sleep quality continues in PD and GAD during remission. Therefore, in this study we aimed to compare the sleep quality of patients with PD and GAD to that of healthy controls. Methods The study included patients with PD (n = 42) and GAD (n = 40) who had been in remission for at least 3 months and healthy control volunteers (n = 45). The patients were administered the Pittsburgh Sleep Quality Index (PSQI), Beck Anxiety Inventory (BAI), and Beck Depression Inventory (BDI). Results The total PSQI scores of the GAD group were significantly increased in comparison to those of the PD (p = 0.009) and control (p < 0.001) groups. The rate of poor sleep quality in GAD during remission (77.5%) was greater than that of the PD (47.6%) and control (51.1%) groups (p = 0.011). Discussion GAD is a chronic and recurrent disease. In this study, it was found that the deterioration in sleep quality of patients with GAD may continue during remission. In the follow-up and treatment of patients, it is appropriate to question about sleep symptoms and to plan interventions according to these symptoms.

Modifiable risk and protective factors for anxiety disorders among adults: A systematic review.

Anxiety disorders are highly prevalent in the general population and associated with high rates of impairment and disability. This burden highlights the need to identify risk factors that individuals can modify without professional intervention. A systematic review was conducted to identify studies that examined modifiable risk and protective factors for anxiety disorders among adults in the general population. Searches were conducted in PubMed, PsycINFO and MEDLINE using medical subject headings and text words related to risk factors, protective factors, and each anxiety disorder. Screening, data extraction, and quality assessment were performed by three study authors. Modifiable risk and protective factors from 19 studies across seven countries were identified. Risk factors identified included cigarette smoking, alcohol use, cannabis use, negative appraisals of life events, avoidance, and occupational factors. Protective factors included social support, coping, and physical activity. Cigarette smoking was the most studied risk factor. Support was found for cigarette smoking as a risk factor for agoraphobia and panic disorder. Mixed results were found for generalized anxiety disorder and specific phobia. Across disorders, smoking frequency was associated with greater risk. Results indicate an important gap in the literature in that few studies have examined modifiable risk factors for anxiety disorders.

Allergic rhinitis increases the risk of incident panic disorder among young individuals: A nationwide population-based cohort study in Taiwan.

BACKGROUND: Studies have reported an association between allergy and panic disorder. However, few studies have explored the relationship between allergic rhinitis and panic disorder. Previous studies were limited by cross-sectional study designs, self-reported symptoms, absence of matched controls, and lack of consideration of the influence of steroid and comorbidities. This study aimed to explore the longitudinal association between allergic rhinitis and panic disorder in a large population-based cohort of young people. METHODS: In this study, 79,917 new cases of allergic rhinitis between 1998 and 2012 in individuals younger than 20 years were identified from Taiwan's National Health Insurance Research Database. One control (nonallergic rhinitis) per case (allergic rhinitis) was randomly selected from the remaining sample, matching for age, sex, residence, and insurance premium. Both groups were followed until the end of 2013 for incidence of panic disorder. Cox regression analysis was performed, adjusting for sex, age, residence, insurance premium, systemic steroids, asthma, atopic dermatitis, allergic conjunctivitis, attention deficit hyperactivity disorder, depression, and Charlson index. RESULTS: Allergic rhinitis was associated with a 2-fold increase in risk for panic disorder after adjustment for other variables. Additional independent risk factor of panic disorders were female sex, older age group, and depression. LIMITATIONS: Lifestyle, substance use, smoking by the patient or family members, and psychosocial stressors were not evaluated. CONCLUSIONS: Allergic rhinitis was associated with increased risk of panic disorder. Assessment and intervention of allergy rhinitis among young people with panic disorder are critical.

Early trauma, attachment experiences and comorbidities in schizophrenia / Relação entre traumas precoces, experiências de apego e comorbidades na esquizofrenia

Abstract Objective To evaluate attachment patterns in subjects with schizophrenia and their relationships to early traumatic events, psychotic symptoms and comorbidities. Methods Twenty patients diagnosed with schizophrenia according to criteria from the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) underwent retrospective symptom assessment and careful assessment of the number and manner of childhood caregiver changes. The Diagnostic Interview for Psychosis and Affective Disorders (DI-PAD) was used to assess symptoms related to schizophrenia (positive and negative symptoms), depression and mania. Anxiety disorder comorbidities were assessed by the Liebowitz Social Anxiety Scale (LSAS), Yale-Brown Obsessions and Compulsions Scale (Y-BOCS) and Panic and Schizophrenia Interview (PaSI). Experience in Close Relationships - Relationship Structures (ECR-RS) and Early Trauma Inventory Self Report-Short Form (ETISR-SF) were used to assess attachment patterns and traumatic history, respectively. Results Moderate and significant correlations between attachment patterns and early trauma showed that greater severity of anxious attachment was predicted by a higher frequency of total early traumas (Spearman ρ = 0.446, p = 0.04), mainly general traumas (ρ = 0.526, p = 0.017; including parental illness and separation, as well as natural disaster and serious accidents). Among the correlations between early trauma and comorbid symptoms, panic attacks occurring before the onset of schizophrenia showed significant and positive correlations with ETISR-SF total scores and the sexual trauma subscale. Conclusion Children with an unstable early emotional life are more vulnerable to the development of psychopathology, such as panic anxiety symptoms. Traumatic events may also predict later schizophrenia.

Resumo Objetivos Avaliar o padrão de apego em portadores de esquizofrenia e discutir a relação que tais padrões apresentam com a sintomatologia psicótica e as comorbidades dos pacientes investigados. Métodos Vinte pacientes diagnosticados com esquizofrenia de acordo com os critérios do Manual Diagnóstico e Estatístico de Transtornos Mentais, 5ª edição (DSM-5) foram submetidos a avaliação de sintomas retrospectivos e avaliação cuidadosa do número e modo de mudança de cuidador da infância. A Entrevista Diagnóstica para Psicoses e Transtornos Afetivos (DI-PAD) foi utilizada para avaliar sintomas relacionados à esquizofrenia (sintomas positivos e negativos), depressão e mania. As comorbidades de transtorno de ansiedade foram avaliadas pela Escala de Ansiedade Social de Liebowitz (LSAS), Escala de Sintomas Obsessivo-Compulsivos de Yale-Brown (Y-BOCS) e Entrevista de Pânico e Esquizofrenia (PaSI). Os instrumentos Questionário das Experiências nas Relações Próximas-Estruturas Relacionais (ECR-RS) e Inventário de Autorrelato de Trauma Precoce - Forma Curta (ETISR-SF) foram utilizados para avaliar padrões de apego e histórico traumático, respectivamente. Resultados Foram identificadas correlações significativas entre a ocorrência de traumas precoces e o apego do tipo ansioso. Também foi verificada a relação entre traumas gerais e sintomas de pânico, constatando-se que as crises de pânico antecipam surtos quando predominam sintomas ansiosos, somáticos, alucinações e ideias delirantes. Foi observado que a ocorrência de traumas precoces contribui para o pânico, elevando o risco de episódios psicóticos. Conclusão . Os resultados indicam que as adversidades ambientais na infância estão associadas com o risco de desenvolvimento de esquizofrenia e de outras psicoses mais tarde na vida.

Body Image Dissatisfaction and Anxiety Trajectories During Adolescence.

The primary goal of this study was to examine the associations between baseline body image dissatisfaction (BID) and subsequent anxiety trajectories in a diverse, community sample of adolescent girls and boys. Participants were 581 adolescents (baseline age: M = 16.1, SD = 0.7; 58% female; 65% non-Hispanic White) from U.S. public high schools. Self-report questionnaires were administered during school at 3 annual assessment waves. Latent growth curve modeling examined the association between baseline BID and growth factors of anxiety disorder symptom trajectories. Covariates included baseline gender, age, race/ethnicity, parental education attainment, body mass index standard scores, and depressive symptoms. Higher BID at baseline was significantly associated with higher initial symptoms of generalized anxiety disorder (GAD), panic disorder (PD), social anxiety disorder (SAD), and significant school avoidance (SSA; ps = .001-.04) but was unrelated to initial separation anxiety disorder (SEP) symptoms (p = .27). Higher baseline BID also was associated with attenuated decreases in SAD symptoms across time (p = .001). Among adolescents with low baseline anxiety symptoms only, higher BID was associated with more attenuated decreases in SAD symptoms (p = .01) and greater increases in PD symptoms (p = .02). BID was unrelated to changes in GAD, SEP, and SSA symptoms (ps = .11-.94). Findings suggest that BID is associated with concurrent symptoms of multiple anxiety disorders and may have a prospective link to SAD and PD symptoms during adolescence. As such, assessing body image issues may be important to assess when identifying adolescents at risk for exacerbated SAD and PD symptoms.

Drug-induced panic attacks: Analysis of cases registered in the French pharmacovigilance database.

BACKGROUND: The potential role of drugs in the onset of panic attacks (PAs) is poorly understood. AIM: The objective of our study was to characterize drug-induced PAs. METHOD: We performed an analysis of PAs registered in the French pharmacovigilance database between 01/01/1985 and 05/11/2014. RESULTS: Among the 163 recorded cases, 136 (83.4%) were directly related to drugs, mainly antidepressants (11.3%, mainly serotonin reuptake inhibitors), mefloquine (7.2%), isotretinoin (5.2%), rimonabant (3.6%) and corticosteroids (4.7%). PAs are labelled in the Summary of Product Characteristics (SmPC) for a minority (8.6%) of these drugs. In 31.4% of these cases, withdrawal of the suspected drug was performed more than a week after the onset of PAs. PAs could also be secondary to another adverse drug reaction (ADR; n = 14, 8.6%), mainly an allergy to antineoplastic or immunomodulating agents. In 13 cases (8.0%), PAs occurred during a drug-withdrawal syndrome, mainly after benzodiazepines or opioids. Most cases (73%) involved patients without any previous psychiatric disorder. CONCLUSION: This is the first pharmacoepidemiological study about iatrogenic PAs. Beside antidepressants, the most often encountered drugs are not indicated for psychiatric diseases. This study also reveals that iatrogenic PAs mostly occur in patients without any psychiatric medical history and that PAs can be triggered by another ADR. Lastly, the many cases with delayed management underline the need to raise awareness of this relatively unknown ADR among physicians, especially since PAs are generally not labelled in SmPCs of the suspected drugs.

Differences in panic psychopathology between smokers with and without asthma.

Cigarette smoking is more common among individuals with asthma compared to those without, resulting in increased risk of morbidity and mortality. However, there has been little exploration of psychological factors that differ between smokers with and without asthma. Thus, the aim of the current study was to examine differences between smokers with and without asthma in terms of anxiety sensitivity, panic symptoms, lifetime history of panic attacks, and lifetime history of panic disorder. Participants were 115 smokers with asthma (55.3% male, Mage = 38.4 years, SD = 11.9) and 120 smokers without asthma (70.6% male, Mage = 37.0 years, SD = 12.8) who were administered a structured diagnostic interview and completed self-report measures. As hypothesized, after controlling for the effects of cigarettes per day, gender, race, and education, smokers with asthma reported higher levels of anxiety sensitivity and panic symptoms and were at an increased risk for having a lifetime history of panic attacks (OR = 3.01) and panic disorder (OR = 2.96) compared to smokers without asthma. Further, group differences in anxiety sensitivity and panic symptoms remained even after removing participants with a lifetime history of panic attacks or panic disorder. These findings suggest that smokers with asthma are a particularly 'at-risk' population for panic psychopathology and likely in need of specialized smoking-related prevention and intervention efforts.

Panic attack history and smoking topography.

BACKGROUND: Little is known about panic attacks and puffing topography, a behavioral index of the value of smoking reinforcement. This study examined smoking style during the course of smoking of a single cigarette among adult daily smokers with and without a history of panic attacks. METHOD: Participants (n=124, Mage=43.9, SD=9.7; 44.4% female) were non-treatment seeking daily smokers. Lifetime panic attack history was assessed via diagnostic assessment; 28.2% (n=35) of the sample had a panic attack history. Participants smoked one cigarette during an ad libitum smoking trial. Puff volume, duration, and inter-puff interval were measured using the Clinical Research Support System (CReSS) pocket device. RESULTS: Regression analyses revealed that panic attack status was not associated with significant differences in average puff volume, duration, or inter-puff interval. Multi-level modeling was used to examine puffing trajectories. Puff-level data revealed that there was a significant quadratic time x panic effect for puff volume and duration. Those with a panic attack history demonstrated relatively sustained levels of both puff volume and duration over time, whereas those without a history of panic attacks demonstrated an increase followed by a decrease in volume and duration over time. These effects were not accounted for by the presence of general psychopathology. DISCUSSION: Smokers with a panic attack history demonstrate more persistent efforts to self-regulate the delivery of nicotine, and thus may be at risk for continued smoking and dependence. Tailored treatment may be needed to address unique vulnerabilities among this group.

Anxiety Symptoms in Psychotic Disorders: Results from the Second Australian National Mental Health Survey.

BACKGROUND: The prevalence of anxiety symptoms among Australians with psychotic disorders was examined as part of the Survey of High Impact Psychosis (SHIP). METHODS: A two-phase design was used. Of 7,955 people who were screened positive for psychosis and eligible, there were 1,825 participants (18-34 years and 35-64 years) interviewed. Data were collected on symptomatology, substance use, cognitive ability, functioning, disability, physical health, mental health service utilization, medication use, education, employment and housing. Anxiety symptomatology was divided into generalized anxiety, panic, phobic, social anxiety and obsessive-compulsive symptoms. RESULTS: The most common ICD-10 diagnoses were schizophrenia or schizoaffective disorder (63.0%) and bipolar (mania) disorder (17.5%). Overall, 59.8% (n=1,092) of participants reported experiencing anxiety symptoms in the previous twelve months. Female gender was highly associated with all domains of anxiety. Smoking was significantly associated with all domains of anxiety, except generalized anxiety. The presence of any depressive symptoms in the previous twelve months was significantly associated with all anxiety symptoms. Medication side effects were associated with phobic and obsessive-compulsive symptoms. Social dysfunction was associated with social anxiety, and less so for obsessive-compulsive symptoms. CONCLUSIONS: Anxiety symptoms are common in people with psychotic disorders. Appropriate screening and treatment should be a clinical priority.

Is panic disorder associated with clinical severity of fibromyalgia? A preliminary study in a tertiary-care centre.

OBJECTIVES: To investigate the influence of panic disorder (PD) with/without agoraphobia on the clinical severity of fibromyalgia (FM). METHODS: Eighty-one patients with FM, among those consecutively referring to a tertiary-care setting, were included in this cross-sectional study. Psychiatric diagnoses were made by the structured clinical interview in accordance with the 4th-TR version of the diagnostic and statistical manual of mental disorders. The clinical severity of FM was measured by means of the following self-administered scales: Fibromyalgia Impact Questionnaire (FIQ), Fibromyalgia Assessment Status (FAS), Health Assessment Questionnaire (HAQ). RESULTS: A final sample of 66 females with FM with or without past PD was included in the analyses. The two groups did not significantly differ in age, years of education, length of illness or medication distribution. We did not find significant differences between the two groups in the FIQ and FAS scale scores, whereas subjects with FM and past PD showed significantly higher HAQ scale scores than those without past PD (p<.001). CONCLUSIONS: A history of PD in patients with FM increases the severity of functional impairment in performing a wide range of daily-life activities, as measured by the HAQ scale, with no effects on the severity of other clinical dimensions of FM. Potential underlying mechanisms and clinical implications will be discussed.

Panic attacks and smoking cessation among cancer patients receiving smoking cessation treatment.

OBJECTIVE: Little is known about factors associated with smoking cessation in cancer patients. This study examined the impact of panic attacks on smoking abstinence likelihood among cancer patients receiving tobacco cessation treatment. METHOD: The relationship of panic attacks to 7-day point-prevalence abstinence at mid-treatment, end of treatment, and 6-month post-end of treatment were examined among cancer patients (N=2255 patients; 50.1% female; Mage=54.9, SD=11.0) who received counseling and pharmacotherapy for smoking cessation. Panic attack history indexed by two questions from the Patient Health Questionnaire (PHQ). Point-prevalence abstinence was assessed via the Timeline Follow-Back. RESULTS: Cancer patients with a history of panic attacks, (n=493, 21.9%) relative to those without, were less likely to be abstinent at mid-treatment (OR=0.79, CI95%=0.64-0.98) and end of treatment (OR=0.72, CI95%=0.58-0.89). After adjusting for significant covariates, panic attack history remained predictive of decreased abstinence likelihood at end of treatment (OR =0.78, CI95%=0.62-0.99). CONCLUSIONS: Panic attacks may be related to poorer cessation outcome during smoking treatment among cancer patients, and may be usefully assessed and targeted for intervention.
