Depression, anxiety, and the COVID-19 pandemic: Severity of symptoms and associated factors among university students after the end of the movement lockdown.

Background and aimsThis online cross-sectional study investigated the severity of depressive, anxiety, and stress symptoms among university students and determined the association between various factors and the levels of depressive and anxiety symptoms in response to the coronavirus disease 2019 (COVID-19) pandemic after the movement control order (MCO) was lifted.MethodsA total of 316 participants were administered a self-report questionnaire that collected data on sociodemographic attributes, personal characteristics, COVID-19-related stressors, religious coping, and clinical characteristics. In addition, the Multidimensional Scale of Perceived Social Support (MSPSS) and the 21-item Depression, Anxiety and Stress Scale (DASS-21) were administered.ResultsRegarding depression, 15.5%, 11.7%, and 9.2% of the participants reported mild, moderate, and severe to extremely severe depression, respectively. For anxiety, 7.0%, 16.5%, and 13.2% of the respondents had mild, moderate, and severe to extremely severe anxiety, respectively. Moreover, 26.3% of participants had mild stress, 9.5% had moderate stress, and 6.6% had severe to extremely severe stress. The multiple linear regression model revealed that frustration because of loss of daily routine and study disruption and having preexisting medical, depressive, and anxiety disorders were associated with elevated depressive symptoms, while a greater degree of family and friends social support was associated with less depressive symptoms after adjusting for age, gender, and marital status. It was also found that frustration because of study disruption and having preexisting medical, depressive, and anxiety disorders were associated with elevated anxiety symptoms, while being enrolled in medicine-based courses and having a greater degree of family support were factors associated with less anxiety symptoms after adjusting for age, gender, and marital status.ConclusionThere is a need to conduct a longitudinal study in the future to confirm the causal relationship between the significant predictive factors and depression and anxiety identified in this study, and maintenance of a persistent flow of academic activities and social interaction may be of utmost importance to safeguard the mental wellbeing of university students.

Fear and Anxiety in COVID-19: Preexisting Anxiety Disorders

The general population has experienced a significant elevation in fear and anxiety during COVID-19 both as a direct result of the virus but also due to measures taken to prevent it spreading, such as the need to stay inside and increase hand-washing. Lockdown has been used in many/most countries to prevent widespread infection. The advice and imposed actions are necessary to prevent the virus from spreading, but they might exacerbate the problems experienced by people with a preexisting anxiety-related disorder. The treatment of anxiety-related disorders can be provided while in quarantine. Staying at home in self-isolation does not preclude obtaining psychological treatment for anxiety-related disorders. Dealing with cognitive biases, over-estimations of threat, intolerance of uncertainty, inflated responsibility and excessive safety behavior, are useful clinical directions.

A longitudinal evaluation of the impact of the COVID-19 pandemic on patients with pre-existing anxiety disorders.

To examine if the COVID-19 pandemic is associated with a differential effect over time in relation to its psychological and social impact on patients with established anxiety disorders. Semi-structured interviews were conducted with 24 individuals attending the Galway-Roscommon Mental Health Services with an International Classification of Diseases (ICD)-10 diagnosis of an anxiety disorder at two time points (six months apart) to determine the impact of the COVID-19 restrictions on anxiety and depressive symptoms, social and occupational functioning and quality of life. No statistical difference in symptomatology was noted between the two time points in relation to anxiety symptoms as measured by utilising psychometric rating scales (BAI and HARS) or utilising a Likert scale. The greatest impact of COVID-19 at both time points is related to social functioning and quality of life. Significant variability was noted for individual participants. Qualitative analysis noted social isolation, concern for the participants' future and increased difficulty managing anxiety with ongoing restrictions. No significant overall change in symptomatology or functioning over time was noted for individuals with pre-existing anxiety disorders. Variability was, however, demonstrated between individuals, with some individuals describing ongoing anxiety, social isolation and concern for their future. Identifying those with ongoing symptoms or distress and providing multidisciplinary support to this cohort is suggested.

What Is the Impact of COVID-19 Pandemic on Patients with Pre-Existing Mood or Anxiety Disorder? An Observational Prospective Study.

Background and Objectives: This observational prospective study aims to examine the psychological and psychopathological impact of the pandemic stress on patients with pre-existing mood, anxiety and obsessive–compulsive disorders. Materials and Methods: The study includes 386 consecutive patients recruited from 10 March to 30 June 2020 among those being treated at the Institute of Psychopathology in Rome (Italy) with an age ≥18 years and meeting DSM-5 criteria for major depressive disorder (MDD) (35.2%), bipolar I (BD-I) (21.5%) or II (BD-II) (28.8%) disorder, obsessive–compulsive disorder (OCD) (7.5%), panic disorder (PD) (7.0%) or social anxiety (SA). A total of 34.2% had lifetime comorbid Axis I disorders and 15.3% had alcohol/drug abuse disorders. Using a semi-structured interview, we investigated if the impact of COVID-19 stress for patients has been similar, higher or lower than that of their family and friends and, for patients with relapse/symptoms worsening, if there was a relationship between the clinical condition worsening and the pandemic stress. Results: Compared with that experienced by their family members and friends, the psychological impact of pandemic stress was similar in 52.1% of the sample, better in 37.1% and worse in 10.8%. In 21 patients (5.4%), the stress triggered a recurrence or worsened the symptoms. Patients with OCD had a higher rate of worsening due to pandemic stress compared to patients with MDD (p = 0.033), although, overall, the χ2 test was not significant among primary diagnoses (χ2 = 8.368; p = 0.057). Conclusions: The psychological and psychopathological consequences of COVID-19 stress in our outpatients were very modest. The continuity of care offered during the lockdown could explain the results.

Impact of anxiety and depression disorders on sustained return to work after work-related musculoskeletal strain or sprain: a gender stratified cohort study.

Objective:The aim of this study was to examine the impact of anxiety and depression disorders on sustained return to work (RTW) for men and women with musculoskeletal strain or sprain.Methods:Accepted lost-time claims for spine and upper-extremity strain or sprain were extracted for workers in the Canadian province of British Columbia from 2009 to 2013 (N=84 925). Pre-existing and new onset anxiety and depression disorders were identified using longitudinal health claims data. Probability of sustained RTW was analyzed using Cox proportional hazards models, stratified by gender and adjusted for potential confounders.Results:For pre-existing disorders, compared to men with no anxiety and no depression, men with anxiety only [hazard ratio (HR) 0.88, 95% confidence interval (CI) 0.84–0.93], depression only (HR 0.94, 95% CI 0.89–1.00), and anxiety and depression (HR 0.93, 95% CI 0.90–0.97) had lower probabilities of sustained RTW in adjusted models. The same direction of effect was found for women, but anxiety only had a smaller effect size among women compared to men (HR anxiety only 0.95, 95% CI 0.92–0.99; HR depression only 0.98, 95% CI 0.93–1.03, HR anxiety and depression 0.94, 95% CI 0.91–0.97). Among men and women, new onset disorders were associated with lower probability of sustained RTW and the effect estimates were larger than for pre-existing disorders.Conclusions:Findings suggest that workers’ compensation benefits and programs intended to improve RTW after musculoskeletal injury should take pre-existing and new onset anxiety and depression disorders into consideration and that gender-sensitive work disability strategies may be warranted.

Longitudinal changes of anxiety and depressive symptoms during the COVID-19 pandemic in Germany: The role of pre-existing anxiety, depressive, and other mental disorders

Especially individuals with mental disorders might experience an escalation of psychopathological symptoms during the COVID-19 pandemic. Therefore, we investigated the role of anxiety, depressive, and other mental disorders for levels and longitudinal changes of COVID-19-related fear, anxiety and depressive symptoms during the first months of the COVID-19 pandemic in Germany. In a longitudinal observational design with four assessment waves from March, 27th until June, 15th 2020, a total of 6,551 adults from Germany was assessed. 4,175 individuals participated in one, 1,070 in two, 803 in three, and 503 in all four waves of data collection. Multilevel analyses revealed that across all assessment waves, COVID-19-related fear, anxiety, and depressive symptoms were significantly higher in individuals with vs. without anxiety, depressive, and other mental disorders. All symptoms decreased on average over time, and this decrease was significantly stronger in individuals with vs. without anxiety disorders, and particularly driven by individuals with generalized anxiety disorder. Our findings suggest that individuals with mental disorders, especially anxiety disorders – and in particular those with a generalized anxiety disorder – seem to be vulnerable to experience psychological strain in the context of the pandemic, might likely overestimate potential threat, and should be targeted by preventive and therapeutic interventions.

Effect of Discontinuation of Nusinersen Treatment in Long-Standing SMA3.

Spinal muscular atrophy is an autosomal recessive neuromuscular disease leading to ongoing degeneration of anterior horn cells in the spinal cord. Nusinersen is the first approved treatment for the condition, an intrathecally administered antisense oligonucleotide. It modulates pre-RNA splicing of the SMN2 gene and increases full-length SMN protein expression, thereby increasing SMN protein levels. The benefit of Nusinersen for patients with spinal muscular atrophy type 3 (SMA3) has recently been shown in several real-world cohorts. We aim to elucidate not only the effect of therapy with Nusinersen, but the development of the disease course after discontinuation of treatment. To our knowledge, there are so far no reports on the effects of Nusinersen discontinuation. We report on a 45-year-old female patient with genetically confirmed SMA3 and a disease duration of 40 years prior to treatment onset. The patient was non-ambulantory, best motor function at treatment onset was holding arms with support, reflected in MRC of 3/5 in upper limbs. After having received Nusinersen for 11 months without complications, the patient showed improvement in motor functions, as measured by hand grip measurement (HGS), Hammersmith Functional Rating Scale Expanded (HFMSE), and Revised Upper Limb Module (RULM). Due to worsening of a pre-existing anxiety disorder, treatment was discontinued after six injections. Sixteen months later, progression of the disease became evident with worsening of HFMSE and RULM scores, while hand strength remained stable. Treatment with Nusinersen in SMA3 improves motor function in longstanding disease even in clinically advanced stages; however, after discontinuation of treatment, further progression mirroring the natural history of the disease is anticipated.

Heightened Levels of Maladaptive Daydreaming Are Associated With COVID-19 Lockdown, Pre-existing Psychiatric Diagnoses, and Intensified Psychological Dysfunctions: A Multi-country Study.

The COVID-19 pandemic has been spreading globally since December 2019, bringing with it anxieties, mortal risk, and agonizing psychological suffering. This study aimed to explore the relationship between maladaptive daydreaming (MD)—an addictive mental behavior to vivid fantasy associated with distress and functional impairment—and forced COVID-19 pandemic-related self-isolation and quarantine. Previous literature indicated that individuals employ MD for the regulation of distress and boredom, wish fulfillment, and entertainment experiences. The literature on the impact of the COVID-19 pandemic on mental health identifies a flareup in psychological difficulties in the general population. In this study we explored the associations between the pandemic threat and mental health indices among individuals with MD. We surveyed 1,565 adults from over 70 countries who responded to calls for participants posted in online MD communities and other general social media sites. Probable MD was determined based on an empirically derived cut-off score on a pertinent measure. After controlling for sociodemographic variables, a series of MANCOVAs, followed by post-hoc ANCOVAs, revealed that individuals with probable MD who were observing lockdown restrictions reported having spent more time in fantasy, experienced more intense and vivid daydreaming, and had a stronger urge to daydream than other participants. Similar statistical procedures indicated that, individuals with probable MD who reported pre-existing anxiety and depression disorders described a greater urge to daydream due to the pandemic and greater difficulty to control this addictive behavior. Compared to individuals with likely normal daydreaming, individuals with suspected MD reported more pandemic-attributed deterioration on a wide array of psychological distress indices. Our data show that the current worldwide pandemic threat is connected with an elevated intensity of this addictive form of mental activity, and that MD is associated with the exacerbation of psychological distress and dysfunction rather than with beneficial regulation of the experienced stressor.

Cerebral Responses to Stationary Emotional Stimuli Measured by fMRI in Women with Persistent Postural-Perceptual Dizziness.

Introduction Persistent postural-perceptual dizziness (PPPD) is a functional vestibular disorder characterized by chronic dizziness, unsteadiness, and hypersensitivity to motion. Preexisting anxiety disorders and neurotic personality traits confer vulnerability to PPPD. High anxiety during acute vertigo or dizziness incites it. A functional magnetic resonance imaging (fMRI) study of chronic subjective dizziness found unexpectedly hypoactive responses to vestibular stimulation in cortical regions that integrate threat assessment and spatial perception. Objective This fMRI study used non-moving, but emotionally charged visual stimuli to investigate the brain's activity of PPPD patients and control subjects. Methods The participants included 16 women with PPPD and 16 age-matched women who recovered completely from acute episodes of vertigo or dizziness capable of triggering PPPD. Brain responses to positive, neutral, and negative figures from the International Affective Picture System were measured with fMRI and compared between the groups. Dizziness handicap, anxiety, and depression were assessed with validated questionnaires. Results Between group analyses: Participants with PPPD showed reduced activity in anterior cingulate cortex and increased activity in left angular gyrus in response to negative versus positive stimuli, which was not observed in recovered individuals. Within group analyses: Participants with PPPD had increased activity in visuospatial areas (parahippocampal gyrus, intraparietal sulcus) in negative versus positive and negative versus neutral contrasts, whereas recovered individuals had increased activity in anxiety regions (amygdala, orbitofrontal cortex). Conclusion Patients with PPPD may be more attuned to spatial elements than to the content of emotionally charged visual stimuli.

Quality of life in patients with chronic wounds

The quality of life of patients with chronic wounds is significantly reduced. Through pain, wound odor, and exudate, they experience limitations in various areas of their daily life. Pain can lead to reduced mobility, sleep disorders, or reduced food intake. Physical limitations caused by the wound itself, dependence on caregivers, and the financial burden are further influencing factors. At the same time, chronic wounds lead to changes in social life, withdrawal from friends and family, and afeeling of powerlessness over apatient's own life. Pre-existing anxiety or adepressive disorder can further negatively influence the quality of life. There are various general and diagnosis-specific assessment tools for measuring the quality of life of patients with chronic wounds. Such asurvey should be carried out regularly in the course of wound therapy. Especially at the beginning of treatment, it is important to identify limiting factors and to evaluate them regularly during wound therapy and to work out possible solutions together with the patient.

Longitudinal Analysis of Depression and Anxiety Symptoms as Independent Predictors of Neurocognitive Function in Primary Brain Tumor Patients

Primary brain tumor patients are vulnerable to depression and anxiety symptoms, which may affect their neurocognitive functioning. We performed a prospective longitudinal analysis to examine the association between depression and anxiety symptoms and domain-specific neurocognitive functioning in primary brain tumor patients receiving radiation therapy (RT). On a prospective trial, 54 primary brain tumor patients receiving RT underwent comprehensive neurocognitive evaluation at baseline (pre-RT), and 3, 6, and 12 months post-RT. Neurocognitive assessments measured attention/processing speed, verbal and visuospatial memory, and executive functioning, including Delis-Kaplan Executive Function System Trail-Making Test (DKEFS-TMT), DKEFS Verbal Fluency, and Brief Visuospatial Memory Test-Revised. Depression and anxiety symptoms were also assessed at each time point with Beck Depression and Anxiety Inventories (BDI-II and BAI), respectively. Higher scores reflect more numerous or severe depression or anxiety symptoms. Univariable and multivariable linear mixed-effects models assessed associations between BDI-II and BAI scores and domain-specific neurocognitive scores over time, controlling for pre-existing depression or anxiety disorders and other patient, tumor, and treatment characteristics. Higher BAI scores were associated with worse attention and processing speed in univariable analyses: DKEFS-TMT visual scanning (P = .003), number sequencing (P = .011), and letter sequencing (P <.001). On multivariable analyses, these associations remained significant (all P ≤ .01). Higher BDI-II scores were also associated with poorer attention/processing speed (DKEFS-TMT Letter Sequencing) in univariable (P = .002) and multivariable (P = .013) models. Higher BAI scores were associated with worse visuospatial memory (Brief Visuospatial Memory Test-Revised Delayed Recall) on univariable (P = .012) but not multivariable analyses (P = .383). Similarly, higher BDI-II scores were associated with poorer executive functioning (DKEFS Verbal Fluency Category Switching) on univariable (P = .031) but not multivariable analyses (P = .198). Among primary brain tumor patients receiving RT, increased depression and anxiety were independently associated with worsened neurocognition, particularly in attention/processing speed. Depression and anxiety symptoms should be controlled for in prospective clinical trials and managed in the clinical setting to optimize neurocognitive functioning.

Impact of the COVID-19 pandemic on patients with pre-existing anxiety disorders attending secondary care.

To examine the psychological and social impact of the COVID-19 pandemic on patients with established anxiety disorders during a period of stringent mandated social restrictions. Semi-structured interviews were conducted with 30 individuals attending the Galway-Roscommon Mental Health Services with an International Classification of Diseases diagnosis of an anxiety disorder to determine the impact of the COVID-19 restrictions on anxiety and mood symptoms, social and occupational functioning and quality of life. Twelve (40.0%) participants described COVID-19 restrictions as having a deleterious impact on their anxiety symptoms. Likert scale measurements noted that the greatest impact of COVID-19 related to social functioning (mean = 4.5, SD = 2.9), with a modest deleterious effect on anxiety symptoms noted (mean = 3.8, SD = 2.9). Clinician rated data noted that 8 (26.7%) participants had disimproved and 14 (46.7%) participants had improved since their previous clinical review, prior to commencement of COVID-19 restrictions. Conditions associated with no 'trigger', such as generalised anxiety disorder, demonstrated a non-significant increase in anxiety symptoms compared to conditions with a 'trigger', such as obsessive compulsive disorder. Psychiatric or physical comorbidity did not substantially impact on symptomatology secondary to COVID-19 mandated restrictions. The psychological and social impact of COVID-19 restrictions on individuals with pre-existing anxiety disorders has been modest with only minimal increases in symptomatology or social impairment noted.

SAT-014 Insulin Treatment in Human Pregnancy Mitigates an Increased Risk of Postpartum Psychological Distress with Maternal Obesity in the Absence of a Pre-Existing Mood and Anxiety Disorder

BACKGROUND: Pregnant women with obesity are at increased risk for peripartum depression. Maternal obesity is also associated with reduced human placental lactogen (hPL) levels, and decreased hPL transcripts were reported in women with clinical depression. In addition, hPL production may be rescued in women with obesity that were subsequently diagnosed with gestational diabetes and treated with insulin (INS). Objective: Study the effect of INS treatment in pregnancy on the risk for postpartum psychological distress (PPD) in women with and without obesity. Study Design: Using data housed at the Manitoba Centre for Health Policy (2002–2017), cohorts of women (ages 15+) with a single live birth with and without obesity were developed using weight (≥85 and <65.6 kg, respectively) and an average (1.63 m) height. Pre-existing mood and anxiety disorders within 5 years preceding delivery as well as gestational hypertension were excluded. After randomly selecting 1 birth per mother, cohorts were stratified by INS treatment during the gestational period. The risk of PPD within 1 year of delivery was assessed by Poisson regression analysis. Models were adjusted for maternal age and area-level income at delivery. Results: The risk of PPD was 27% greater among women with obesity versus without (adjusted rate ratio (aRR)=1.27, 95% CI 1.16–1.4, p<0.0001). However, women with obesity treated with INS did not have a significantly different risk of PPD compared to women without obesity whether treated with INS (aRR=0.99, 95%CI 0.48–2.02, p=0.974) or not (aRR=1.16, 95%CI 0.86–1.56, p=0.328). This suggests that the risk of PPD among women with obesity may be reduced by INS treatment; however, our ability to detect a significant difference may be limited by small cohort numbers (46 women with obesity received INS in pregnancy) or confounders for receiving INS in pregnancy. Direct comparison of INS treatment within weight groups faced the same limitations but trended toward a reduction in women with obesity who received INS (aRR=0.91, 95%CI 0.68–1.22, p=0.531). The positive association between INS treatment in pregnancy and decreased risk of PPD in women with obesity was lost when pre-existing mood and anxiety disorder was not excluded. Inclusion of pre-existing diabetes in the adjusted models did not improve model fit or contribute significantly to the differences in PPD rates. Conclusions: Maternal obesity increases the risk for PPD but this risk may be reduced by gestational INS treatment in the absence of a pre-existing mood and anxiety disorders. This correlates with the decrease and increase in hPL levels reported previously with maternal obesity without and with INS treatment (for diabetes) in pregnancy, respectively. Thus, hPL levels may serve as a possible indicator of PPD risk and a potential target for gestational INS treatment.

Mental health conditions diagnosed before bilateral oophorectomy: a population-based case-control study.

We studied eight mental health conditions diagnosed before bilateral oophorectomy performed for nonmalignant indications. We identified 1,653 premenopausal women who underwent bilateral oophorectomy for a nonmalignant indication in Olmsted County, Minnesota, during a 20-year period (1988-2007). Each woman was matched by age (±1 year) to one population-based control who had not undergone bilateral oophorectomy before the index date (age range: 21-49 years). Both cases and controls were identified using the records-linkage system of the Rochester Epidemiology Project (REP http://www.rochesterproject.org). For eight mental health conditions, we calculated odds ratios (ORs) and their 95% confidence intervals (95% CIs) adjusted for race, education, and income using conditional logistic regression. Pre-existing mood disorders, anxiety disorders, and somatoform disorders were associated with increased risk of bilateral oophorectomy in overall analyses. These associations were also significant in women ≤45 years of age at index date. Personality disorders were associated with increased risk only in overall analyses and adjustment disorders only in women 46 to 49 years of age. Some of the associations were significantly different across strata by age at index date and by indication. There was also a linear trend of increasing adjusted ORs from 1.55 (95% CI 1.31-1.83) for one mental health condition to 2.19 (95% CI 1.40-3.41) for three or more conditions (trend P < 0.001). We identified several mental health conditions that were associated with bilateral oophorectomy for nonmalignant indications. Awareness of these associations may guide women and physicians in future decision-making and limit unindicated bilateral oophorectomies. VIDEO SUMMARY:: http://links.lww.com/MENO/A458.

Going to Altitude with a Preexisting Psychiatric Condition.

Psychiatric disorders have a high lifetime prevalence affecting about 30% of the global population. Not much is known about high altitude (HA) sojourns in individuals living with a psychiatric condition. This lack of scientific evidence contrasts with the anticipated increase in numbers of individuals with preexisting psychiatric conditions seeking medical advice on HA exposure. Not only are there risks associated with a HA climb, but physical activity in general is known to improve symptoms of many psychiatric disorder and enhance measures of mental well-being like quality of life and resilience. There are additional positive effects of alpine environments on mental health beyond those of physical activity. All individuals going to HA with a preexisting psychiatric condition should be in a state of stable disease with no recent change in medication. Specific considerations and recommendations apply to individual psychiatric disorders. During the HA sojourn the challenge is to separate altitude-related symptoms such as insomnia from prodromal symptoms of the underlying disorder (e.g., depressive episode) or altitude-related hyperventilation from panic attacks. In case an individual with preexisting anxiety disorder decides to go to HA there might be a predisposition toward acute mountain sickness (AMS), but it should always be considered that many symptoms of anxiety and AMS overlap. Any medication that is anticipated to be taken during ascent or at HA should be tested for compatibility with the psychiatric condition and medication before the trip.

Biological and psychosocial predictors of anxiety worsening in the postpartum period: A longitudinal study

BackgroundAs many as 20% of women will experience an anxiety disorder during the perinatal period. Women with pre-existing anxiety disorders are at increased risk of worsening during this time, yet little is known about its predictors. Study AimTo investigate the psychosocial and biological risk factors for anxiety worsening in the postpartum in women with pre-existing anxiety disorders. MethodsThirty-five (n = 35) pregnant women with pre-existing DSM-5 anxiety disorders were enrolled in this prospective study investigating the psychosocial (e.g., childhood trauma, intolerance of uncertainty, depression) and biological risk factors (e.g. C-reactive protein, interleukin-6, tumor necrosis factor-α) for anxiety worsening in the postpartum period. Anxiety worsening was defined as an increase of ≥50% or greater on Hamilton Anxiety Rating Scale scores from the third trimester of pregnancy (32.94 ± 3.35 weeks) to six weeks postpartum. ResultsIntolerance of uncertainty, depressive symptom severity, and obsessive-compulsive disorder symptoms present in pregnancy were significant predictors of anxiety worsening in the postpartum. LimitationsSample heterogeneity and limited sample size may affect study generalizability. ConclusionsTo our knowledge, this is the first longitudinal study to investigate psychosocial and biological risk factors for anxiety worsening in the postpartum in women with pre-existing anxiety disorders. Continued research investigating these risk factors is needed to elucidate whether they differ from women experiencing new-onset anxiety disorders in the perinatal period, and those in non-puerperal groups. Identifying these risk factors can guide the development of screening measures for early and accurate symptom detection. This can lead to the implementation of appropriate interventions aimed at decreasing the risk of perinatal anxiety worsening.

Conditional probabilities of substance use disorders and associated risk factors: Progression from first use to use disorder on alcohol, cannabis, stimulants, sedatives and opioids

BackgroundRelatively little is known about factors that may lead to the development of a substance use disorder (SUD), across a range of drug classes. This study aimed to identify factors that predict the likelihood of transition from use to SUD and the speed with which this may occur at the population level, with a focus on the impact of pre-existing mental disorders. MethodsData were collected as part of the 2007 Australian National Survey of Mental Health and Wellbeing, a nationally representative survey of 8841 Australian adults. A series of discrete time survival analyses were undertaken on data pertaining to the age of onset of use and symptoms of use disorder, for alcohol, cannabis, sedatives, stimulants, and opioids, as well as the impact of pre-existing mood and anxiety disorders on the likelihood of developing a SUD. ResultsLifetime cumulative probability estimates indicated that 50.4% of stimulant, 46.6% of opioid, 39% of sedative, 37.5% of alcohol, and 34.1% of cannabis users would develop a SUD on those substances, within an estimated 14, 12, 8, 30, and 23 years after onset respectively. Pre-existing mental disorders were significantly associated with increased risk of developing a SUD for alcohol, cannabis and stimulant use disorder. ConclusionThe relative speed associated with the transition from use to SUD emphasizes the narrow window of time available to intervene, underscoring the urgency of early identification of mental health conditions and the timely provision of appropriate evidence-based interventions, which could potentially prevent the development of secondary SUDs.

Anxiety disorders and stressful events in Takotsubo syndrome.

Anxiety disorders are more common in Takotsubo syndrome (TS) than in acute coronary syndrome patients. The aim of this study was to investigate whether pre-existing anxiety disorders predispose to TS triggered by exclusively emotional stressful events. Triggering events were compared in 58 TS patients with and without pre-existing anxiety disorders; clinical, electrocardiographic and echocardiographic data were also collected. Thirty-one (53%) patients had a previous history of anxiety disorders. The exclusively emotional stressful event-rate was higher in TS patients with pre-existing anxiety disorder (74% vs. 30%, p = 0.001), while TS caused by an undetermined trigger were significantly higher in patients without anxiety disorders (33% vs. 10%, p = 0.027). Moreover, in TS patients without a previous history of anxiety disorders, a trend of higher prevalence of physical events was found (16% vs. 37%, p = 0.07). In patients with pre-existing anxiety disorders, TS was predominantly triggered by exclusively emotional stressful events, thereby suggesting a possible relationship between anxiety and emotional cardiac frailty in TS patients.

Prevalence Rates and Predictors of Generalized Anxiety Disorder Symptoms in Residents of Fort McMurray Six Months After a Wildfire.

The Fort McMurray wildfire was the costliest disaster in Canadian history, with far-reaching impacts. The purpose of this paper is to examine the prevalence and risk factors of elevated generalized anxiety disorder (GAD) symptomatology in residents of Fort McMurray 6 months after the wildfire. Data were collected via random selection procedures from 486 participants. Generalized anxiety disorder symptoms were measured via the GAD-7. The 1-month prevalence rate for GAD symptomatology 6 months after the disaster was 19.8% overall, regression analyses revealed six variables with significant unique contributions to prediction of GAD symptomatology. Significant predictors were: pre-existing anxiety disorder, witnessing of homes being destroyed by the wildfire, living in a different home after the wildfire, receiving limited governmental support or limited family support, and receiving counseling after the wildfire. Participants with these risk factors were between two to nearly seven times more likely to present with GAD symptomatology. In addition, participants who presented with elevated symptomatology were more likely to increase use or problematically use substances post-disaster. This study extends the literature on mental health conditions and risk factors following disasters, specifically in the area of generalized anxiety. Findings and implications are discussed.
