Treatment-Resistant Late-Life Depression: A Review of Clinical Features, Neuropsychology, Neurobiology, and Treatment.

Major depression is common in older adults (≥ 60 years of age), termed late-life depression (LLD). Up to 30% of these patients will have treatment-resistant late-life depression (TRLLD), defined as depression that persists despite two adequate antidepressant trials. TRLLD is challenging for clinicians, given several etiological factors (eg, neurocognitive conditions, medical comorbidities, anxiety, and sleep disruption). Proper assessment and management is critical, as individuals with TRLLD often present in medical settings and suffer from cognitive decline and other marks of accelerated aging. This article serves as an evidence-based guide for medical practitioners who encounter TRLLD in their practice.

Impact of the COVID-19 pandemic on the mental health and well-being of Veterans' spouses: a cross sectional analysis.

BACKGROUND: COVID-19 has negatively impacted the mental health and well-being of both Canadians and the world as a whole, with Veterans, in particular, showing increased rates of depression, anxiety, and PTSD. Spouses and common-law partners often serve as primary caregivers and sources of support for Veterans, which may have a deleterious effect on mental health and increase risk of burnout. Pandemic related stressors may increase burden and further exacerbate distress; yet the effect of the pandemic on the mental health and well-being of Veterans' spouses is currently unknown. This study explores the self-reported mental health and well-being of a group of spouses of Canadian Armed Forces Veterans and their adoption of new ways to access healthcare remotely (telehealth), using baseline data from an ongoing longitudinal survey. METHODS: Between July 2020 and February 2021, 365 spouses of Veterans completed an online survey regarding their general mental health, lifestyle changes, and experiences relating to the COVID-19 pandemic. Also completed were questions relating to their use of and satisfaction with health-care treatment services during the pandemic. RESULTS: Reported rates of probable major depressive disorder (MDD), generalized anxiety disorder (GAD), alcohol use disorder (AUD), and PTSD were higher than the general public, with 50-61% believing their symptoms either directly related to or were made worse by the pandemic. Those reporting being exposed to COVID-19 were found to have significantly higher absolute scores on mental health measures than those reporting no exposure. Over 56% reported using telehealth during the pandemic, with over 70% stating they would continue its use post-pandemic. CONCLUSIONS: This is the first Canadian study to examine the impact of the COVID-19 pandemic specifically on the mental health and well-being of Veterans' spouses. Subjectively, the pandemic negatively affected the mental health of this group, however, the pre-pandemic rate for mental health issues in this population is unknown. These results have important implications pertaining to future avenues of research and clinical/programme development post-pandemic, particularly relating to the potential need for increased support for spouses of Veterans, both as individuals and in their role as supports for Veterans.

Prevalence and patterns of major depressive disorder and subthreshold depressive symptoms in south China.

BACKGROUND: Information on major depressive disorder (MDD) and subthreshold depressive symptoms (SDS) is rarely reported in south China. This study examines the prevalence rates and patterns of MDD and SDS of a large representative sample of adult residents in south China. METHODS: The Guangdong Mental Health Survey was conducted on adults (over 18 years) from September to December 2021. Multistage stratified cluster sampling was used and face-to-face interviews were done with a two-stage design by trained lay interviewers and psychiatrists. A total of 16,377 inhabitants were interviewed using standardized assessment tools. Data were weighted to adjust for differential probabilities of selection and differential response. RESULTS: The weighted prevalence rates of MDD and SDS were 2.5 % (95%CI: 2.2 %-2.9 %) and 14.7 % (95%CI: 14.0 %-15.5 %), respectively. Multinomial logistic regression analysis revealed that female, younger age, living in urban area, higher education, unmarried, irregular meal pattern, lack of physical exercise, chronic diseases, irregular napping pattern and short sleep were positively associated with SDS. Besides, female, younger age, unmarried, irregular meal pattern, lack of physical exercise, chronic diseases, short sleep and poor mental health were positively associated with MDD. LIMITATIONS: The cross-sectional nature of the study limited causal inferences. CONCLUSIONS: The prevalence of MDD in Guangdong province in 2021 is higher than in mainland China in 2013. Given the higher prevalence of SDS, and high burden of depression, it also offers valuable opportunities for policymakers and health-care professionals to explore the factors affecting mental health in Guangdong province, especially during the COVID-19 epidemic.

Loneliness, internalizing symptoms, and inflammatory markers in adolescent COVID-19 survivors.

BACKGROUND: Concerns about the psychiatric sequelae after COVID-19 infection have increased as the pandemic spreads worldwide. The increase in self-isolation during this pandemic period has also revealed the importance of feelings of loneliness. This study aimed to examine the relationship between baseline inflammation levels, internalizing symptoms, and feelings of loneliness in adolescent COVID-19 survivors in the long term. METHODS: A total of 74 adolescents (41 girls, 55.4%, mean age 14.88) and their parents were included in the study. This cross-sectional study assessed internalizing symptoms via Revised Children's Anxiety and Depression Scale (RCADS) and feelings of loneliness using the UCLA-loneliness scale. Baseline inflammatory markers at COVID-19 diagnosis were collected. Logistic regression analysis was used to determine predictors for depression in adolescents. RESULTS: The most common disorder was Major Depressive Disorder (MDD) (25.7%), and 33.8% of the adolescents were in the clinical range in at least one internalizing domain. Baseline C-Reactive Protein (CRP) levels correlated weakly with MDD scores. Loneliness scores correlated with all internalizing symptoms, strong association with MDD scores. Loneliness, anxiety, and parental anxiety were associated with an increased likelihood of MDD. Baseline CRP positivity did not predict MDD in adolescent COVID-19 survivors. CONCLUSIONS: This study indicates that anxiety, loneliness, and parental anxiety play an important role in adolescents' experience of depressive symptoms after COVID-19 infection. Thus, screening parental psychopathology and loneliness in COVID-19 survivors seems to be preventive for adolescent mental health problems.

Physical and mental health impact of the COVID-19 pandemic at first year in a Spanish adult cohort.

The COVID-19 pandemic and the political and health measures have profoundly affected the health of our populations. However, very few studies have been published assessing its impact using a prospective cohort. The aim of this study is to describe the impact on physical and mental health due to the COVID-19 pandemic in the general population in Spain, and according to COVID-19 clinical status, during the first year of the pandemic. A longitudinal cohort study with two online surveys were performed on a representative sample of the adult Spanish population before (N = 2005, October/November 2019) and during the pandemic (N = 1357, November/December 2020). We assessed disability using the World Health Organisation Disability Assessment Schedule (WHODAS), major depressive episode (MDE) and suicidal thoughts and behaviours (STB), using an adapted version of the Composite International Diagnostic Interview (CIDI 3.0); generalised anxiety disorder (GAD) using the GAD-7 scale; post-traumatic stress disorder (PTSD) symptoms using the PTSD checklist for DSM-5 (PCL-5). For physical health, there was a statistically significant loss of weight (mean/SD) (T0, 73.22/15.56 vs. T1, 71.21/11.94), less use of tobacco (T0, 11.4% vs. T1, 9.0%) and decreased disability (mean/SD) (T0, 21.52/9.22 vs. T1, 19.03/7.32). For mental health, there was a significant increase in MDE (T0, 6.5% vs. T1, 8.8%) and in the prevalence of GAD (T0, 13.7% vs. T1, 17.7%). The prevalence of STB (T0, 15.1% vs. T1, 7.1%) significantly decreased. Individuals who declared they had been diagnosed with COVID-19 (3.6%) showed a worsening in physical health and an increase in mental health problems and PTSD symptoms. Although suicide risk during the first year of the pandemic was significantly less, many suicide risk factors increased: such as the incidence and persistence of MDE and GAD, the presence of PTSD symptoms in those diagnosed with COVID-19, and a worsening in self-assessed health status. We expect an increase in STB in the population in the long-term. Future research should gather information about the long-term impact of the pandemic.

Prevalence, Correlates, and Psychiatric Burden of Prolonged Grief Disorder in U.S. Military Veterans: Results From a Nationally Representative Study.

OBJECTIVES: To examine the point prevalence and correlates of prolonged grief disorder (PGD) in a nationally-representative sample of United States (U.S.) veterans. METHODS: Data were analyzed from the National Health and Resilience in Veterans Study, a nationally representative study of 2,441 U.S. veterans. RESULTS: A total of 158 (weighted 7.3%) veterans screened positive for PGD. The strongest correlates of PGD were adverse childhood experiences, female sex, non-natural causes of death, knowing someone who died from coronavirus disease 2019, and number of close losses. After adjusting for sociodemographic, military, and trauma variables, veterans with PGD were 5-to-9 times more likely to screen positive for post-traumatic stress disorder, major depressive disorder, and generalized anxiety disorder. After additional adjustment for current psychiatric and substance use disorders, they were 2-3 times more likely to endorse suicidal thoughts and behaviors. CONCLUSIONS: Results underscore the importance of targeting PGD as an independent risk factor for psychiatric disorders and suicide risk.

What factors explain the changes in major depressive disorder symptoms by age group during the COVID-19 pandemic? A longitudinal study.

BACKGROUND: Data collected during the COVID-19 pandemic suggest an increase in major depressive disorder (MDD) among younger adults. The current study aims to assess the association of age groups and MDD risk before and during the COVID-19 pandemic and quantify the effect of potential mediating variables such as loneliness, social support, resilience, and socioeconomic factors. METHODS: A representative sample of Spanish adults was interviewed before (2019, N = 1880) and during (2020, N = 1103) the COVID-19 pandemic. MDD was assessed using the CIDI, loneliness through the UCLA scale, social support through the OSSS-3, resilience with the 6-BRS, and worsened economic circumstances and unemployment through a single question. Mixed-models were used to study changes in MDD by age group. Regression models were constructed to quantify the association between age and potential mediators, as well as their mediating effect on the association between age group and MDD. RESULTS: Among the younger age cohorts (18-29 and 30-44 years) the probability of having MDD during the pandemic increased from 0.04 (95 % CI: 0.002-0.09) to 0.25 (0.12-0.39) and from 0.02 (-0.001-0.03) to 0.11 (0.04-0.17), respectively. Some 36.6 % of the association between age and risk of MDD during the pandemic was explained by loneliness (12.0 %), low resilience (10.7 %), and worsened economic situation (13.9 %). LIMITATIONS: Reliance on self-report data and generalizability of the findings limited to the Spanish population. CONCLUSIONS: Strategies to decrease the impact of a pandemic on depressive symptoms among young adults should address loneliness, provide tools to improve resilience, and enjoy improved financial support.

Mental Health Service Utilization Rates Among Commercially Insured Adults in the US During the First Year of the COVID-19 Pandemic.

Importance: The COVID-19 pandemic has been associated with an elevated prevalence of mental health conditions and disrupted mental health care throughout the US. Objective: To examine mental health service use among US adults from January through December 2020. Design, Setting, and Participants: This cohort study used county-level service utilization data from a national US database of commercial medical claims from adults (age >18 years) from January 5 to December 21, 2020. All analyses were conducted in April and May 2021. Main Outcomes and Measures: Per-week use of mental health services per 10 000 beneficiaries was calculated for 5 psychiatric diagnostic categories: major depressive disorder (MDD), anxiety disorders, bipolar disorder, adjustment disorders, and posttraumatic stress disorder (PTSD). Changes in service utilization rates following the declaration of a national public health emergency on March 13, 2020, were examined overall and by service modality (in-person vs telehealth), diagnostic category, patient sex, and age group. Results: The study included 5 142 577 commercially insured adults. The COVID-19 pandemic was associated with more than a 50% decline in in-person mental health care service utilization rates. At baseline, there was a mean (SD) of 11.66 (118.00) weekly beneficiaries receiving services for MDD per 10 000 enrollees; this declined by 6.44 weekly beneficiaries per 10 000 enrollees (ß, -6.44; 95% CI, -8.33 to -4.54). For other disorders, these rates were as follows: anxiety disorders (mean [SD] baseline, 12.24 [129.40] beneficiaries per 10 000 enrollees; ß, -5.28; 95% CI, -7.50 to -3.05), bipolar disorder (mean [SD] baseline, 3.32 [60.39] beneficiaries per 10 000 enrollees; ß, -1.81; 95% CI, -2.75 to -0.87), adjustment disorders (mean [SD] baseline, 12.14 [129.94] beneficiaries per 10 000 enrollees; ß, -6.78; 95% CI, -8.51 to -5.04), and PTSD (mean [SD] baseline, 4.93 [114.23] beneficiaries per 10 000 enrollees; ß, -2.00; 95% CI, -3.98 to -0.02). Over the same period, there was a 16- to 20-fold increase in telehealth service utilization; the rate of increase was lowest for bipolar disorder (mean [SD] baseline, 0.13 [16.72] beneficiaries per 10 000 enrollees; ß, 1.40; 95% CI, 1.04-1.76) and highest for anxiety disorders (mean [SD] baseline, 0.20 [9.28] beneficiaries per 10 000 enrollees; ß, 9.12; 95% CI, 7.32-10.92). When combining in-person and telehealth service utilization rates, an overall increase in care for MDD, anxiety, and adjustment disorders was observed over the period. Conclusions and Relevance: In this cohort study of US adults, we found that the COVID-19 pandemic was associated with a rapid increase in telehealth services for mental health conditions, offsetting a sharp decline in in-person care and generating overall higher service utilization rates for several mental health conditions compared with prepandemic levels.

Comparing the centrality symptoms of major depressive disorder samples across junior high school students, senior high school students, college students and elderly adults during city lockdown of COVID-19 pandemic-A network analysis.

INTRODUCTION: Recently, in the view of network analysis, depression has been conceptualized as a complex and dynamic network model combining individual symptoms. To date, no studies have systematically examined and compared depressive symptom networks across different populations. METHODS: A total of 36,105 participants were recruited and asked to complete the Patient Health Questionnaire-9 among junior high school students, senior high school students, college students, and elderly adults who were more susceptible to depression during the COVID-19 lockdown in China. In the analysis, we applied the optimal cutoff score ≥ 8 for students and a score ≥ 6 for elderly adults to identify 5830 participants who were likely to be depressed. The index of "strength" was used to identify central symptoms in the network structure. RESULTS: The results showed that Sad Mood was the most central symptom among junior high school students, senior high school students, and college students, but the most central symptom in the elderly was Guilt. Among the top three central symptoms, Suicide Ideation was unique to senior high school students, while Anhedonia was most prevalent among college students. Guilt - Suicide Ideation, Anhedonia - Energy, Anhedonia - Sad Mood, and Sleep - Energy showed the strongest association among junior and senior high school students, college students, and elderly adults, respectively. NCT (i.e., Network Comparison Test) suggested that the network's global connectivity was ultimately inconsistent, but the network structure remained roughly intact. CONCLUSION: In treatment, targeting central symptoms may be critical to alleviating depression.

Low Resilience Was a Risk Factor of Mental Health Problems during the COVID-19 Pandemic but Not in Individuals Exposed to COVID-19: A Cohort Study in Spanish Adult General Population.

BACKGROUND: The aim is to analyze whether people with low resilience are at higher risk of mental health problems during the COVID-19 pandemic in Spanish adults. METHODS: a longitudinal cohort study was carried out. Resilience was measured with the CD-RISC. Mental health problems that were assessed included: Major Depressive Episode (MDE), Generalized Anxiety Disorder (GAD), Suicidal Thoughts and Behaviors (STB), and Posttraumatic Stress Disorder (PTSD) symptoms. RESULTS: we found statistically significant differences between groups and resilience scores in MDE [F (3; 48.40) = 19.55], GAD [F (3; 19.63) = 6.45] and STB [F (3; 111.74) = 31.94]. Multivariable analyses showed individuals with very low resilience were at a 5-fold risk of Incidence of MDE and a 4-fold risk of STB. Persistent group presented a 21-fold risk of MDE and 54-fold risk of STB. No evidence of higher risk was found for GAD. Individuals with low resilience and exposed to COVID-19 were not at higher risk. Individuals with low resilience were at higher risk of PTSD in general population [ß(95% CI) = -3.25 (-3.969 to -2.54)], but not for individuals with COVID-19. CONCLUSIONS: in the general population, having low or very low resilience increases the risk of suffering MDE, STB, and PTSD, but not GAD during the COVID-19 pandemic, and not in the population with COVID-19.

Hope in Psychiatric Patients: An Observational Study in a Psychiatric Rehabilitation Centre.

INTRODUCTION: The COVID-19 pandemic has led to the re-evaluation of some fundamental aspects for the management of emotions and psychological dynamics. Hope and its lack are important factors that have been especially evaluated in caregivers and HCWs. Instead, our study aimed to explore hopelessness among psychiatric rehabilitation center residents with Primary Psychosis. METHODS: We recruited 116 inpatients affected by Primary Psychosis (schizophrenia, bipolar disorder, major depression disorder and personality disorder). Hopelessness was sought through the BHS, during the covid-19 pandemic period. They were compared with data from previous studies on HCWs (HealthCare Workers), in the same period, and in the same centre. RESULTS: The results obtained in this group of patients showed high total scores on the BHS scale (mean total score: 7.28±SD 3.73). These data are significantly higher than those found in HWs in the same pandemic period (mean total score: 3.74±SD 3.62). Among the different disorders the borderline personality disorder patients have presented the highest score (mean total score: 8.00±SD 3.50). CONCLUSION: Understanding resident - and HCWs- level variations in hopelessness may be important for targeting interventions to improve the outcome of residential psychiatric patients.

Allergic reaction induced by subcutaneous administration of ketamine: a case report.

Ketamine can be used for depression and suicidal ideation due to its effectiveness and low complication rates; moreover, allergic reactions are rare. Immediately after subcutaneous (SC) ketamine administration, a 22-year-old man rapidly developed hives on the trunk and face without oxygen desaturation. Symptoms disappeared after treatment with prednisolone. This case presents an allergic reaction to ketamine compatible with mast cell activation and release of preformed mediators, without being able to prove whether the event was mediated by immunoglobulin E. This is the only case reported to date of an allergic reaction to SC ketamine for psychiatric treatment.

Loneliness associates strongly with anxiety and depression during the COVID pandemic, especially in men and younger adults.

Loneliness is associated with major depressive disorder (MDD), and likely also with generalized anxiety disorder (GAD). It is unclear if these associations are moderated by age, sex, or genetic susceptibility for MDD. We included 75,279 individuals from the Lifelines COVID-19 study, a longitudinal study of a Dutch population-based cohort. Participants completed up to sixteen digital questionnaires between March 2020 and January 2021, yielding a total of 616,129 observations. Loneliness was assessed with the Three-Item Loneliness Scale, and MDD and GAD with the Mini-International Neuropsychiatric Interview. We used generalized estimating equations to investigate the association between loneliness and MDD and GAD, and whether this association varied across time, age, sex and MDD polygenic risk. Loneliness was strongly associated with all MDD and GAD outcomes. Individuals with the highest loneliness scores were around 14 times more likely to have MDD, and 11 times more likely to have GAD, compared to individuals who reported the least loneliness. The association between loneliness and MDD symptoms was stronger in men, younger individuals, and increased across time. While MDD polygenic risk predicted MDD and GAD outcomes, we did not find an interaction effect with loneliness. Our study, which is the largest to date, confirms that loneliness is an important risk factor for MDD, GAD, depressive and anxiety symptoms, especially in men and younger individuals. Future studies should investigate the mechanisms of these associations and explore loneliness-based interventions to prevent and treat MDD and GAD.

A prospective study of transdiagnostic psychiatric symptoms associated with burnout and functional difficulties in COVID-19 frontline healthcare workers.

OBJECTIVE: Frontline healthcare workers (FHCWs) responding to the COVID-19 pandemic develop posttraumatic stress disorder (PTSD), major depressive disorder (MDD) and generalized anxiety disorder (GAD) symptoms. Such symptoms are associated with burnout, occupational and relational difficulties. In the current study, we examined the prospective association between acute transdiagnostic COVID-19-related PTSD, MDD, and GAD symptoms at pandemic outset, and burnout and functional difficulties several months later in FHCWs in New York City. METHODS: Wave 1 symptoms of COVID-19-related PTSD, MDD, and GAD, were assessed in 787 FHCWs from April 14 to May 11th, 2020. Burnout and occupational difficulties were assessed at wave 1 and wave 2, approximately 7 months later. RESULTS: After adjusting for wave 1 burnout, wave 1 MDD symptoms, particularly sleep difficulties, loss of interest, and feeling tired/having little energy, collectively explained 42% incremental variance in this outcome. After adjusting for wave 1 work difficulties, MDD and PTSD symptoms, particularly feeling tired/having little energy, loss of interest, and negative expectations of self/world, collectively explained 42% incremental variance in this outcome. After adjusting for wave 1 relationship difficulties, MDD, GAD, and PTSD symptoms, particularly depressed mood, irritability, and appetite disturbance, explained 26% incremental variance in this outcome. CONCLUSIONS: Results highlight psychiatric symptoms assessed during the acute phase of the COVID-19 pandemic that may help predict burnout and work and relationship difficulties in FHCWs. Early interventions aimed at ameliorating transdiagnostic symptoms of MDD, PTSD, and GAD may help mitigate risk for burnout and functional difficulties in this population.

Mood-congruent negative thinking styles and cognitive vulnerability in depressed COVID-19 survivors: A comparison with major depressive disorder.

BACKGROUND: COVID-19 is associated with depressive psychopathology in survivors. Negative thinking styles are a core feature of major depression, fostering the experience of negative emotions and affects and hampering recovery. This cognitive vulnerability has been observed in medical conditions associated with depression, but never explored in post-COVID depression. METHODS: We studied 729 participants: 362 COVID-19 survivors, 73 inpatients with Major Depressive Disorder (MDD), and 294 healthy participants (HC). Severity of depression was self-rated on the Zung Self-Rating Depression Scale (ZSDS). Neuropsychological bias toward negative emotional stimuli and the negative outlook on the self were tested in a self-description task, yielding latencies and frequencies of attribution of morally tuned elements. Dimensions of negative thinking and depressive cognitive style in evaluation of hypothetical events were measured on the Cognition Questionnaire (CQ). RESULTS: 22.4% COVID survivors self-rated depression above the clinical threshold. Frequencies and latencies of attribution of morally negative elements, and CQ scores, correlated between themselves and predicted ZSDS scores, with post-COVID depressed patients showing intermediate scores between the more severe MDD patients, and non-depressed post-COVID participants and HC. LIMITATIONS: Recruitment was in a single center, thus raising the possibility of population stratification. CONCLUSIONS: The breadth of self-reproach and depressive cognitive style in evaluating events showed the same association with severity of depression in MDD and in post-COVID depressed patients, distributing along a gradient of severity, thus suggesting that individual features of negative thinking styles are shared in these conditions, and should be addressed as treatment targets in depressed COVID-19 survivors.

Prevalence of suicidality in clinically stable patients with major depressive disorder during the COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic is associated with an increased risk of mental health problems including suicide in many subpopulations, but its influence on stable patients with major depressive disorder (MDD) has been studied fleetingly. This study examined the one-year prevalence of suicidality including suicidal ideation (SI), suicide plans (SP), and suicide attempts (SA) as well as their correlates in clinically stable MDD patients during the COVID-19 pandemic. METHODS: A cross-sectional, observational study was conducted between October 1, 2020, and October 15, 2021, in six tertiary psychiatric hospitals. Socio-demographic information, clinical data and one-year prevalence of suicidality were recorded. RESULTS: Altogether, 1718 participants who met the eligibility criteria were included. The overall one-year prevalence of suicidality during the COVID-19 pandemic was 68.04% (95% confidence intervals (CI) =65.84-70.25%), with one-year SI prevalence of 66.4% (95%CI = 64.18-68.65%), SP prevalence of 36.26% (95%CI = 33.99-38.54%), and SA prevalence of 39.35% (95%CI = 37.04-41.66%). Binary logistic regression analyses revealed male gender, married marital status, college education level and above and age were negatively associated with risk of suicidality. Urban residence, unemployed work status, experiences of cyberbullying, a history of suicide among family members or friends, and more severe fatigue, physical pain, and residual depressive symptoms were positively associated with risk of suicidality. CONCLUSIONS: Suicidality is common among clinically stable MDD patients during the COVID-19 pandemic. Regular suicide screening and preventive measures should be provided to clinically stable MDD patients during the pandemic.

Psychological state of a sample of patients with mood disorders during the first French COVID-19 lockdown.

Since the beginning of the COVID-19 pandemic, evidence shows the negative psychological impact of lockdown measures in the general population. It is also important to identify predictors of psychological distress in vulnerable people, particularly patients with history of depressive episodes (the most prevalent psychiatric disorder), in order to adapt mental health strategies for future lockdown measures. This study aim was to (1) compare in 69 healthy controls (HC) and 346 patients with a major depressive episode in the two previous years (PP) self-reported psychological symptoms (depression, anxiety, insomnia, suicidal ideation, traumatic stress, anger) and living conditions during the first national French lockdown, and (2) identify predictors of significant psychological distress in PP. The levels of psychological symptoms were very low in HC compared with PP, independently of the living conditions. Half of PP had no psychiatric contact during the lockdown. Loneliness and boredom were independent predictors of depression, anxiety and insomnia, whereas daily physical activity was a protective factor. Virtual contacts protected against suicidal ideation. Our results highlight the need of specific strategies to target loneliness and boredom and to improve care access, including telepsychiatry. Longitudinal studies must investigate the COVID-19 pandemic psychological impact in clinical samples.

Discontinuation of Continuation or Maintenance Electroconvulsive Therapy Caused by the COVID-19 Pandemic: A Naturalistic Study Investigating Relapse in Patients With Major Depressive Disorder.

BACKGROUND: Continuation or maintenance electroconvulsive therapy (C/M-ECT) is recommended to reduce relapse rates of patients with major depressive disorder. During the ongoing COVID-19 pandemic, ECT services have come under pressure or needed to close because of redirected resources and safety reasons. We investigated the impact of C/M-ECT discontinuation on relapse in patients with unipolar depressive disorder in Flanders, Belgium. METHODS: Between March 30 and June 18, 2020, all patients receiving C/M-ECT in 2 ECT centers were included. Continuation or maintenance electroconvulsive therapy was discontinued in 33 patients and continued in 4 patients. Relapse was defined as the need to restart ECT or the need for hospitalization. Depressive symptoms were assessed every 3 weeks using the Patient Health Questionnaire, the Clinical Global Impression Scale, and 2 additional patient-rated questions. RESULTS: Relapse in the discontinuation group was 60.6%. All 4 patients who continued ECT remained remitted. Kaplan-Meier survival analysis showed significantly shorter relapse rates for patients receiving bitemporal and/or frequent C/M-ECT (1- to 2-week intervals). Patients older than 60 years showed longer survival rates. CONCLUSIONS: Our results confirm earlier prospective and retrospective data regarding the efficacy and importance of C/M-ECT as relapse prevention. After treatment discontinuation, close monitoring of early warning signs for relapse is crucial, especially in the first few months. With the COVID-19 pandemic continuing, our data provide an indication of the necessity to ensure adequate care and access to ECT not only for the acutely ill but also for the vulnerable patients who are depending on C/M-ECT.

Two rTMS sessions per week: a practical approach for treating major depressive disorder.

INTRODUCTION: Depression is one of the leading causes of disability in the world, and a disease that contributes greatly to the global burden of disease. Repetitive transcranial magnetic stimulation (rTMS) has proven to be a well-tolerated, effective treatment for depression. The present study was designed to evaluate the efficacy of an rTMS treatment scheme with a fewer number of sessions per week. METHODS: In total 91 adult university students with major depressive disorder (MDD). This was a double-blind, randomized clinical trial in which 15 sessions of rTMS were given to each one of two treatment groups made up of adults with active MDD. One treatment group received two sessions per week, the other received five. The study protocol included their respective sham rTMS groups. The patients who received active rTMS also participated in a follow-up procedure that consisted of two sessions of active rTMS per month for three more months. RESULTS: Measurements by the Hamilton Rating Scale for Depression (HAMD) showed that the groups which received active rTMS had higher percentages of antidepressant response at 96 and 95.5% for five and two sessions/week, respectively, compared to the sham rTMS groups: 27.3 and 4.5% for five and two sessions/week, respectively. Observations at the end of the 3-month follow-up phase showed that the improvements in HAMD scores were maintained in both groups. CONCLUSION: This study contributes to demonstrating that rTMS with a more practical schedule of two sessions/week is an effective antidepressant treatment that could be considered the first choice for managing symptoms of depression.

Identification of psychological features and development of an assessment tool for event-related psychological distress after experiencing non-traumatic stressful events.

Stressful events in daily life that are non-traumatic (e.g., family-, school-, work-, interpersonal-, and health-related problems) frequently cause various mood disturbances. For some people, being exposed to non-traumatic but stressful events could trigger the onset and relapse of mood disorders. Furthermore, non-traumatic stressful events also cause event-related psychological distress (ERPD), similar to that of post-traumatic stress disorder (PTSD; i.e., intense intrusive imagery or memory recall, avoidance, and hyperarousal) in the general population and individuals with mood disorders. However, previous ERPD studies only showed that people with ERPD display PTSD-like symptoms after non-traumatic experiences; they failed to get to the crux of the matter by only utilizing trauma- or PTSD-related assessment tools. We thus aimed to identify the psychological phenomena and features of ERPD after individuals experienced non-traumatic stressful events, and to develop and validate an appropriate ERPD assessment tool. First, we conducted a qualitative study to obtain the psychological features through interviews with 22 individuals (mean age = 41.50 years old, SD = 12.24) with major depressive disorder or bipolar disorder. Second, in the quantitative component, we implemented a web-based survey with 747 participants of the general population (mean age = 41.96 years old, SD = 12.64) by using ERPD-related questionnaires created based on the qualitative study; then, we examined the reliability and validity of the ERPD assessment tool. Results yielded that the psychological features of ERPD comprised four factors: feelings of revenge, rumination, self-denial, and mental paralysis. These were utilized in the developed 24-item measure of ERPD-a novel self-report assessment tool. For various professionals involved in mental healthcare, this tool can be used to clarify and assess psychological phenomena in people with ERPD.
