Subcutaneous ketamine reduces suicide risk and improves functioning in depression: A proof-of-concept study

This investigation explores the efficacy of subcutaneous ketamine for mitigating depressive symptoms and suicidal ideation, addressing a crucial need for rapid-onset treatments in severe depression cases. It introduces an innovative approach to administering an NMDA receptor antagonist, significantly advancing psychopharmacological methods for treating suicidal behaviors as distinct entities, even within depressive episodes. The study's objective is to assess the impact of subcutaneous ketamine on diminishing suicidal thoughts and mood symptoms during depressive episodes through a naturalistic, prospective observational design. Conducted at Hospital de Clínicas de Porto Alegre, Brazil, between 2021 and 2023, the study involved 26 patients undergoing a current depressive episode. Of these, 23 completed the acute phase of treatment, and 18 were followed up for 6 months. The treatment regimen commenced with a ketamine dose of 0.5 mg/kg, which was adjusted according to individual responses under psychiatric supervision. The findings revealed substantial decreases in Columbia Suicide Severity Rating Scale scores following multiple ketamine sessions, with most patients achieving remission after approximately eight sessions. A notable reduction in depressive symptoms was also observed. A clear dose-response relationship was established, indicating that higher doses of ketamine were associated with more significant improvements in depressive symptoms, suicidal ideation, and overall functionality. Follow-up assessments suggested that these improvements were sustained over time. The subcutaneous administration of ketamine was generally well-tolerated, with minor and short-lived side effects. The study posits that subcutaneous ketamine may present a promising solution for treating severe depression accompanied by suicidal tendencies, particularly considering its positive influence on patient functionality and well-being. This method could offer a cost-effective and accessible treatment alternative, especially relevant in settings with limited resources. Given its potential in reducing long-term disability and economic viability, the study advocates for its broader application and further validation through larger, controlled trials.Trial Registration: ClinicalTrials.gov NCT05249309.

Efficacy of cognitive training on cognition, symptoms and functioning: Impact of motivation and attendance

While cognitive remediation therapy (CRT) and compensatory strategy training both have large literature bases supporting their efficacy on both proximal and distal outcomes, the research base on stand-alone cognitive training (CT) is smaller and less consistent, with little information about factors associated with better outcomes. In this study, we examined the efficacy of CT on training task, cognitive, symptom, and functional ability measures as well as the impact of motivational interviewing (MI), motivation level, and session attendance on treatment outcomes. Adults with psychotic spectrum disorders (n = 114) were randomized to MI or a sham control interview (CI), followed by 4 months of computerized CT. In whole sample analyses, participants improved on training tasks, cognitive performance, and psychiatric symptoms, but self-reported cognition, self-reported depression, and functional ability did not change. Compared to CI, MI was associated with greater reductions in self-reported depressive symptoms. Motivation level and session attendance did not significantly influence outcomes. Findings support the efficacy of CT on several key outcomes, and its simplicity may be advantageous in uptake in community clinics with limited staffing. The lack of functional gains underscores the need to incorporate treatment ingredients that promote generalization and real-world implementation of learned skills. We also speculate that engagement during course of training may be a better predictor of training success than baseline task-specific motivation.

Client predictors of dropouts and outcomes in psychotherapy for generalized anxiety disorder: an exploratory study

ABSTRACT This study is a secondary analysis exploring client predictors of dropouts and outcomes in the treatment of generalized anxiety disorder (GAD). Data was taken from a feasibility randomized control trial (RCT) exploring the relative efficacy of emotion-focused therapy (EFT) compared with cognitive-behavioral therapy (CBT). Relationships between client characteristics and dropouts were explored using logistic regression analysis. Relationships between client characteristics and psychotherapy outcomes were explored using hierarchical linear regression analyses. For the full dataset (n = 58), a comorbid personality disorder predicted a higher number of dropouts. Eleven participants dropped out of therapy. Having a disability predicted less improvement in symptoms of depression and general distress. Being male-identified predicted a greater reduction in symptoms of anxiety and general distress, and comorbid agoraphobia predicted a greater reduction in symptoms of depression for the CBT condition (n = 21 completers). For the EFT condition (n = 26 completers), being older predicted greater improvements in symptoms of anxiety and comorbid panic disorder predicted a lower reduction in symptoms of depression. Caution should be taken in interpreting these findings given the small number of participants. However, they provide useful insights for the generation of hypotheses in relation to predictors of dropouts and outcomes for future studies.

Exploring the Relationship of Leisure Travel with Loneliness, Depression, and Cognitive Function in Older Adults.

Loneliness, depression, and cognitive decline are pressing concerns among older adults. This study examines the association between leisure travel participation and these health outcomes in older adults, aiming to provide further evidence of the benefits of leisure travel. Using nationally representative historical data from the 2006 household survey of the Health and Retirement Study, this study conducted a series of regression analyses to investigate the relationship between traveling and the three health outcomes, adjusting for age, sex, race, marital status, education, total wealth, annual income, and difficulty with daily activities. The results reveal that travel patterns in terms of distance are significantly associated with loneliness, depression, and cognitive function. Long-distance travel is positively related to higher cognitive function and a reduction in depressive symptoms, along with lower levels of loneliness, reinforcing the notion that leisure travel can potentially act as a catalyst for improved cognitive and mental health by offering opportunities for enhancing social connections and forming new relationships. The findings on the relationships between participation in leisure travel and mental and cognitive health contribute to the body of evidence supporting the therapeutic value of leisure travel in promoting healthy aging and enhancing the overall well-being in older adults.

Adherence to the Mediterranean Diet in Saudi Arabia and Its Association with Socioeconomic Status and Depression.

Background and Objectives: Several RCTs have reported significant reductions in depression symptoms with the Mediterranean diet (MedDiet), but observational studies have reported inconsistent findings. Moreover, studies have rarely investigated the mediating role of socioeconomic status (SES), including objective material status, in adherence to the MedDiet and its impact on depressive symptoms in the same population. Therefore, this cross-sectional study investigated the relationship between adherence to the MedDiet, socioeconomic factors, and depression severity. Materials and Methods: A cross-sectional online survey was conducted between June and December 2022 across Saudia Arabia. The snowball sampling technique was used to recruit participants aged ≥18 years. Mediterranean diet adherence screener (MEDAS) and Patient Health Questionnaire-9 (PHQ-9) were used to assess adherence to the MedDiet and depression severity. An SES index, validated in the Saudi Arabian context, was used to assess SES. The data were analyzed using the Chi-square and Pearson's correlation tests. Results: Only 21% of our study population (n = 467) was MedDiet adherent. Adherence was significantly associated with education (p = 0.014) but not employment status among traditional SES indicators. Similarly, only television ownership (p = 0.009) was associated with MedDiet adherence among the 20 objective material possessions investigated. Nonetheless, the MedDiet-adherent group had a significantly lower PHQ-9 score than the non-adherent group (6.16 ± 0.68 vs. 8.35 ± 0.31, p = 0.002). A moderate but significantly negative correlation between MEDAS and PHQ-9 scores (r = -0.16, p = 0.001) was noted. Conclusions: MedDiet adherence was associated with lower depression severity scores. In addition to education and television ownership, adherence was not associated with any objective indicators of SES.

Comparison of changes in stress coping strategies between cognitive behavioral therapy and pharmacotherapy.

Coping refers to conscious responses to negative circumstances, with the intention of ameliorating these situations. Few studies have compared the differences between psychotherapy and medication treatment for coping strategies for depression. In this study, we investigated the differences in coping strategies between cognitive behavioral therapy (CBT) combined with medication (CBT group) and medication alone (pharmacotherapy group) among outpatients with depression. A prospective observational study was conducted among 50 patients with major depression (24 and 26 in the CBT and pharmacotherapy groups, respectively). Stress coping strategies (Coping Inventory for Stressful Situations [CISS]) and depression severity (Beck Depression Inventory-Second Edition [BDI-II]) were assessed at baseline and 16 weeks later. Changes in the CISS and BDI-II scores in both groups were tested using repeated analysis of variance. Inverse probability weighting with propensity score analysis was applied to address potential selection bias. At 16 weeks, the CBT group exhibited increased CISS task-oriented coping, distraction, and social diversion scores, which differed from those of the pharmacotherapy group. The CBT group exhibited a significantly greater reduction in depressive symptoms than the pharmacotherapy group. This study was not a randomized controlled trial and thus may have selection bias. Gaining adaptive coping skills, including task-oriented coping, distraction, and social diversion skills, by combining CBT with medication may lead to greater improvement in depression symptoms. These findings suggest that clinicians should evaluate coping strategies and facilitate the acquisition of adaptive coping strategies in patients with depression to reduce their symptoms.

Is behavioural activation an effective treatment for depression in children and adolescents? An updated systematic review and meta-analysis.

Behavioural Activation (BA)-a brief therapy based on the scheduling of enjoyable, purposeful and rewarding activities-is an effective and cost-effective treatment for depression in adults that shows promise for children and adolescents. We provide an update on a previous systematic review of evidence on BA-delivered in-person, telephone, or online-for depression and comorbid anxiety in children and adolescents.We conducted systematic literature searches in 6 databases up to February 2024. We included all study designs evaluating BA with participants up to 18years old with diagnosable depression, as established by a validated screening tool or diagnostic manual. We used the Moncrieff Scale and the Cochrane Risk of Bias tool to assess study quality. We summarised the findings of all study types with a narrative synthesis and of randomised controlled trials (RCTs) with a meta-analysis.Overall, 24 studies (6 RCTs, 18 pre-post evaluations, n = 2,758) met our inclusion criteria. A meta-analysis of 4 RCTs (n = 156) showed that BA has a small effect of 0.24 (Hedge's adjusted g) in reducing depression symptoms compared to a waiting-list control, usual care and other therapies. Online and telephone-facilitated BA was shown to be feasible in 3 studies and effective in 1. Outcomes on comorbid anxiety were mixed. No economic evaluations met our inclusion criteria.BA shows sufficient promise as an intervention for reducing depression symptoms in children and adolescents to justify the need for further RCTs, providing that five conditions are met: studies are powered to detect a minimal clinically important difference; BA materials are fit-for-purpose to produce clinically meaningful change; follow-ups are longer than 6months; primary outcomes are child-reported; and intervention costs, resource use and adverse events are reported.

Outcomes of transdiagnostic internet-delivered cognitive behavioural therapy tailored to public safety personnel: A longitudinal observational study

First responders and other public safety personnel (PSP) experience high rates of mental health problems and face barriers to accessing mental healthcare. Internet-delivered cognitive behavioural therapy (ICBT) is an effective and accessible treatment for various mental health concerns. Canadian PSP report favorable attitudes toward ICBT, and preliminary outcomes demonstrate that they benefit from it. Expanding on this research, the current study consisted of a longitudinal observational study of 560 Canadian PSP who participated in ICBT. It was designed to assess the longer term effectiveness of ICBT and moderators of outcomes by gender, linguistic and occupational group, and years of occupational experience. We evaluated symptom change at 8, 26, and 52 weeks post-enrollment, and results among PSP who had elevated clinical scores, showed large reductions (Hedges’ g) in symptoms of depression (g = 1.3), anxiety (g =1.48), posttraumatic stress (g =1.24), panic (g =1.19), and anger (g =1.07) and moderate reductions in symptoms of social anxiety (g =.48–.56). Moderator analyses revealed modest differences in pre-treatment symptoms among certain groups but no group differences in symptom change over time. Clients showed good completion of treatment materials and reported high treatment satisfaction. The results suggest further study of ICBT tailored to PSP is warranted, including evaluating ICBT tailored for PSP in other countries.

A Randomized Evaluation of MoodFX, a Patient-Centred e-Health Tool to Support Outcome Measurement for Depression: Une évaluation randomisée de MoodFX, un outil de santé en ligne centré sur le patient pour soutenir la mesure du résultat dans la dépression.

e-Health tools using validated questionnaires to assess outcomes may facilitate measurement-based care for psychiatric disorders. MoodFX was created as a free online symptom tracker to support patients for outcome measurement in their depression treatment. We conducted a pilot randomized evaluation to examine its usability, and clinical utility. Patients presenting with a major depressive episode (within a major depressive or bipolar disorder) were randomly assigned to receive either MoodFX or a health information website as the intervention and control condition, respectively, with follow-up assessment surveys conducted online at baseline, 8 weeks and 6 months. The primary usability outcomes included the percentage of patients with self-reported use of MoodFX 3 or more times during follow up (indicating minimally adequate usage) and usability measures based on the System Usability Scale (SUS). Secondary clinical outcomes included the Quick Inventory of Depressive Symptomatology, Self-Rated (QIDS-SR) and Patient Health Questionnaire (PHQ-9). Forty-nine participants were randomized (24 to MoodFX and 25 to the control condition). Of the 23 participants randomized to MoodFX who completed the user survey, 18 (78%) used MoodFX 3 or more times over the 6 months of the study. The mean SUS score of 72.7 (65th-69th percentile) represents good usability. Compared to the control group, the MoodFX group had significantly better improvement on QIDS-SR and PHQ-9 scores, with large effect sizes and higher response rates at 6 months. There were no differences between conditions on other secondary outcomes such as functioning and quality of life. MoodFX demonstrated good usability and was associated with reduction in depressive symptoms. This pilot study supports the use of digital tools in depression treatment.

Quality of Life and Depression Symptoms After Therapy De-Escalation in HPV+ Oropharyngeal Squamous Cell Carcinoma

Despite interest in therapy de-escalation for survivors of human papillomavirus-mediated oropharyngeal squamous cell carcinoma (HPV-positive OPSCC), the association of de-escalated therapy with patient-reported quality of life (QoL) outcomes and burden of depressive symptoms remains unclear. To identify associations between clinicopathologic and therapeutic variables with patient-reported QoL outcomes and depression symptom burden in patients with HPV-positive OPSCC, who were enrolled in a therapy de-escalation trial. In this nonrandomized controlled, open-label, curative-intent therapy de-escalation clinical trial in adults with stage I, II, and III HPV-positive OPSCC, patients were recruited from a high-volume head and neck oncology practice. The main outcomes of this study included quantitative, patient-reported QoL and depression symptoms per well-validated inventories. Patient-reported QoL was based on Functional Assessment of Cancer Therapy-Head & Neck (FACT-HN) scores (range, 0-148; lower score indicates inferior QoL). Patient-reported depression-related symptom burden was based on Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR) scores (range, 0-27; a higher score indicates a higher burden of depression symptoms). Baseline clinicopathologic and treatment variables were paired with FACT-HN and QIDS-SR scores at baseline, 3, 6, 12, 24, and 36 months. Linear mixed-effect models with a random intercept were used for each participant and fixed effects for other measures. Regression coefficients are reported with 95% CIs. A total of 95 patients were followed up for a median (IQR) of 2.2 (1.6-3.2) years. Of these, 93 patients (98%) were male with a mean (SD) age of 60.5 (8.2) years. Overall, 54 participants (57%) had a history of current or former smoking, 47 (50%) underwent curative-intent surgery (with or without adjuvant therapy), and 48 (50%) underwent primary radiotherapy (with or without chemotherapy). The median (IQR) radiotherapy dose was 60 (60-70) Gy. Five deaths and 2 recurrence events were observed (mean [SD] recurrence interval, 1.4 [1.5] years). A higher radiotherapy dose was the only modifiable factor associated with inferior patient-reported QoL (lower FACT-HN) (coefficient, -0.66 [95% CI, -1.09 to -0.23]) and greater burden of depression-related symptoms (higher QIDS-SR) (coefficient, 0.11 [95% CI, 0.04-0.19]). With the 70-Gy dose as reference, improvements in FACT-HN and QIDS-SR scores were identified when patients received 51 to 60 Gy (coefficient, 12.75 [95% CI, 4.58-20.92] and -2.17 [-3.49 to -0.85], respectively) and 50 Gy or lower (coefficient, 15.03 [4.36-25.69] and -2.80 [-4.55 to -1.04]). In this nonrandomized controlled, open-label, curative-intent therapy de-escalation trial, a higher radiotherapy dose was associated with inferior patient-reported QoL and a greater burden of depression-related symptoms. This suggests opportunities for improved QoL outcomes and reduced depression symptom burden with a reduction in radiotherapy dose. ClinicalTrials.gov Identifier: NCT04638465.

Emotion Regulation as a Mechanism of Mindfulness in Individual Cognitive-Behavioral Therapy for Depression and Anxiety Disorders

Background. The global prevalence of depression and anxiety disorders underscores the need for a more profound comprehension of effective treatments. Mindfulness has shown promise in enhancing treatment outcomes and preventing relapse in these conditions, but the underlying mechanisms remain poorly understood. Methods. This study examined the role of emotion regulation as a mediator in the relationship between changes in mindfulness and the reduction of depression and anxiety symptoms during individual cognitive-behavioral therapy (CBT). We tracked longitudinal changes in mindfulness, emotion regulation, depression, and anxiety at baseline (pre), early treatment (session 5), midtreatment (session 15), and posttreatment (session 25) in 162 patients with depression and anxiety disorders. Further, we examined whether the effects of mindfulness on emotion regulation could be enhanced by introducing a brief mindfulness intervention at the beginning of each CBT session, as compared to progressive muscle relaxation and individual psychotherapy without any standardized session-introducing interventions. Results. Multilevel structural equation modeling indicated that decreases in rumination and increases in reappraisal and acceptance mediated the relationship between mindfulness and reductions in depressive symptoms. In contrast, reductions in avoidance explained the association between mindfulness and changes in anxiety symptoms. These links remained unchanged when adding a mindfulness intervention into individual CBT. Conclusion. Results support emotion regulatory properties of mindfulness and highlight distinct pathways of symptom reduction in depression and anxiety. These findings have important implications for understanding the mechanisms of mindfulness and tailoring treatment to individual patient needs. This trial is registered with NTC02270073.

275 Cultural Adaptation and Implementation of Cognitive Behavior Therapy in a Rural Mental Health Clinic of Puerto Rico

OBJECTIVES/GOALS: Culturally Centered Cognitive-Behavioral Therapy (CCCBT) is a therapeutic approach that acknowledges the effect of cultural values, beliefs, and norms on mental health. Study aims to develop a CCCBT for rural community by enhancing engagement, relevance, and outcomes through culturally tailored interventions, and evaluate its implementation. METHODS/STUDY POPULATION: Diverse mixed methods study with participants ages 18-65 from Partial Hospitalization Program in rural community located in Puerto Rico Mountain region. CCCBT intervention will have a span of 9 consecutive bi-weekly sessions. The study consists of 2 phases: 1. Evaluate intervention acceptability through focus groups (n=12) with repeated measures to learn about enhancing mental health outcomes, 2. Measure intervention effectiveness in reducing mild-moderate depression and anxiety symptoms using validated questionnaires (PHQ-9 and GAD-7) with a 100 participants from same region. Descriptive analysis for sociodemographic characteristics will be used to provide overview of participants characteristics. Qualitative analysis of focus groups will be obtained through feedback and content analysis. RESULTS/ANTICIPATED RESULTS: We anticipate high intervention acceptability through positive participant feedback and cultural relevance feedback from focal groups. We expect to find significant reduction in symptoms of depression and anxiety post-intervention, demonstrating the efficacy of CCCBT in Puerto Rican rural communities. These results will support the feasibility of implementing this approach, addressing mental health disparities, and enhancing treatment engagement and outcomes in underserved populations. The study will inform future research to refine and expand this intervention in rural communities of Hispanics and/or other rural underserved populations in the US. DISCUSSION/SIGNIFICANCE: This study’s success will advance culturally tailored mental health care in underserved rural Puerto Rican communities, reducing disparities and enhancing treatment relevance and engagement, with potential implications for improving mental health outcomes in similar populations in the US and worldwide.

All in the Family: Does Grandparenting Impact Chinese Grandparents’ Depressive Symptoms?

Grandparenting is becoming increasingly prevalent worldwide, especially in Chinese society. However, the impact of grandparenting on older adults’ health remains unclear. This study examined whether and how grandparenting is associated with depressive symptoms in Chinese older adults and the role of intergenerational support (i.e., financial, emotional, and instrumental support) in this relationship. Using data from the China Longitudinal Aging Social Survey (CLASS) 2018 wave, the researchers employed multivariate linear regression models to investigate variations in depressive symptoms and their associations with grandparenting; the role of intergenerational support was also explored. The results indicated that older adults who engage in grandparenting, particularly in non-intensive care, experience a reduction in depressive symptoms, even after accounting for sociodemographic and health-related factors. Overall, intergenerational support plays a mediating role in the relationship between grandparenting and associated mental health outcomes. Bidirectional emotional and financial support and receiving instrumental support were associated with lower depressive symptoms among Chinese grandparents. In general, the findings of this study suggest that grandparenting, along with intergenerational support, provides certain protective health benefits for Chinese grandparents. With rapid changes in Chinese society, further prospective longitudinal studies are needed to examine family contexts in the relationship between grandchild caregiving and associated health outcomes.

The effectiveness of a Lactobacillus probiotic on measures of psychosocial health in adults diagnosed with subthreshold depression: a double-blind, randomised, placebo-controlled trial

Depression is the leading cause of disability worldwide(1). The microbiota-gut-brain axis may play a role in the aetiology of depression, and probiotics show promise for improving mood and depressive state(2). Further evidence is required to support mechanisms and in high-risk populations, such as those with sub-threshold depression (which may be 2-3 times more prevalent than diagnosed depression)(3). The aims were to assess the efficacy of a probiotic compared with placebo in reducing the severity of depressive symptoms in participants with subthreshold depression, and to investigate potential mechanistic markers of inflammatory, antioxidant status and stress response. A double-blind, randomised, placebo-controlled trial was conducted in participants meeting diagnosis of subthreshold depression (DSM-5); aged 18-65 years; ≥18.5 kg/m2 body mass index; not taking antidepressants, centrally acting medications, probiotics nor antibiotics for at least 6 weeks. The probiotic (4 × 109 AFU/CFU, 2.5 g freeze-dried powder containing Lactobacillus fermentum LF16 (DSM26956), L. rhamnosus LR06 (DSM21981), L. plantarum LP01 (LMG P-21021), Bifidobacterium longum BL04 (DSM 23233)) or placebo was taken daily for 3-months. Data was collected at 3 study visits (pre-, mid- (6 weeks), post-intervention). Self-reported questionnaires measured psychological symptoms (Beck Depression Inventory, BDI; Hospital Anxiety Depression Scale, HADS) and quality of life. Blood and salivary samples were collected for biomarkers including cortisol awakening response (CAR). General linear models examined within-group and between-group differences across all time points. Thirty-nine participants completed the study (n = 19 probiotic; n = 20 placebo) using intention-to-treat analysis. The probiotic group decreased in BDI score by −6.5 (95% CI −12.3; −0.7) and −7.6 (95% CI −13.4; −1.8) at 6 and 12 weeks, respectively. The HADS-A score decreased in the probiotic group by −2.8 (95% CI −5.2; −0.4) and −2.7 (95% CI −5.1; −0.3) at 6 and 12, respectively. The HADS-D score decreased in the probiotic group by −3.0 (95% CI −5.4; −0.7) and −2.5 (−4.9; −0.2) at 6 and 12 weeks of intervention, respectively. No between group differences were found. There were no changes in perceived stress or quality of life scores. The probiotic group had reduced hs-CRP levels (7286.2 ± 1205.8 ng/dL vs. 5976.4 ± 1408.3; P = 0.003) and increased total glutathione (14.2 ± 8.9 ng/dL vs. 9.3 ± 4.7; P = 0.049) compared to placebo, post intervention. Lower levels of CAR were found in the probiotic compared to placebo (−0.04 ± 0.17 μg/dL vs. 0.16 ± 0.25; P = 0.009). A significant reduction in depressive symptoms and anxiety was observed within the probiotic group only. These results were supported by improvements observed in biomarkers, suggesting probiotics may improve psychological wellbeing in adults experiencing sub-threshold depression, by potential pathways involved in central nervous system homeostasis and inflammation. Future analyses are required to understand changes within the intestinal microbiota and to clarify how their metabolites facilitate emotional processing.

EMOTION RELEASING PROCESS AS A NEW APPROACH TO EASE UNCOMFORTABLE EMOTION: A CASE SERIES

Introduction – This paper explores the potential of the Emotion Releasing Process (ERP) as a therapeutic approach for individuals suffering from anxiety and depression, often stemming from traumatic memories. This case series aims to describe two cases using ERP as a therapeutic approach for individuals dealing with anxiety and depression. Methods – The study investigates the effectiveness of ERP through case series analyses of two individuals experiencing significant emotional distress. Results – Both cases demonstrated substantial reductions in anxiety and depression symptoms (56.25% and 93.75% decrease in HSCL scores) following a single ERP session. The paper highlights the unique strengths of ERP compared to traditional methods like CBT and psychodynamics, emphasizing its focus on directly addressing emotional sensations in the body rather than cognitive restructuring or storytelling. Discuss – Traumatic memories are different from ordinary memories in several ways. The emotional impact of traumatic memories can be significant. In addition to the emotional impact of traumatic memories, they can also have physical effects on the body. Conclusion - This approach, bypassing the need for detailed memory recall, holds promise for individuals struggling to verbalize or confront traumatic experiences. Further research is encouraged to explore the broader applications of ERP across various diagnoses and specific trauma types such as PTSD or complex trauma. Keywords: ERP, emotion, trauma, psychotherapy

노인 재학대 예방 프로그램의 효과성에 대한 연구

This study developed an elder re-abuse prevention program targeting perpetrators and assessed its effectiveness through a mixed-method approach. Thirteen perpetrators participated in eight sessions, and quantitative results revealed positive effects on emotional control and reduction of depressive symptoms. However, no significant change was observed in self-esteem. Qualitative findings indicated notable shifts in perpetrators’ emotions, perceptions, actions, and their relationship with elder abuse victims. The trust relationship with social workers in charge, and the negative conditions of perpetrators emerged as influencing factors for these changes. The results suggest the need for enhanced follow-up monitoring of elder abuse cases, interdisciplinary or multi-systematic interventions based on family systems, and strategic workforce deployment for elder abuse prevention programs.

Proximity to public green spaces and depressive symptoms among South African residents: a population-based study

BackgroundExposure to green spaces has been suggested to improve mental health and may reduce the risk of depression. However, there is generally limited evidence on the association between green spaces and depression originating from low-and middle-income countries and Africa in particular. Here, we investigate the association between proximity to public green spaces and depressive symptoms among residents of Gauteng Province, South Africa.MethodsWe used data from the 2017/2018 Gauteng quality of life survey. We included all individuals aged 18 years or older residing in the nine municipalities of Gauteng Province that completed the survey (n = 24,341). Depressive symptoms were assessed using the Patient Health Questionnaire-2. Proximity to public green spaces was defined as self-reported walking time (either less or greater than 15 min) from individuals’ homes to the nearest public green space. To assess the association between access to public green spaces and depressive symptoms, we used mixed-effects models, adjusted for age, sex, population group (African, Indian/Asian, Coloured (mixed race), and White), educational attainment, and municipality. We additionally performed stratified analyses by age, sex, educational attainment, and population group to evaluate whether associations differed within subgroups. Associations are expressed as prevalence ratios (PR) and their 95% confidence intervals (95% CI).ResultsWe observed a 6% (PR = 0.94, 95%CI = 0.92–0.96) prevalence reduction in depressive symptoms for individuals who reported that the nearest public green space was less than 15 min from their homes as compared to those who reported > 15 min. After stratification, this inverse association was stronger among females, individuals aged 35–59 years,those with higher levels of educational attainment, and Coloured individuals as compared to their counterparts.ConclusionOur findings suggest that public green spaces close to residential homes may be associated with a reduction in the occurrence of depressive symptoms among urban populations in resource-constrained settings like South Africa.

Efficacy of intravenous ketamine and intranasal esketamine with dose escalation for Major depression: A systematic review and meta-analysis

ObjectiveIntravenous (IV) racemic ketamine and intranasal (IN) esketamine have demonstrated rapid antidepressant effects in treatment-resistant depression (TRD). This systematic review aims to evaluate the efficacy and safety of ketamine and esketamine at various dosages for depression. MethodsWe included randomized controlled trials (RCTs) with parallel group dose comparison of ketamine and esketamine for depression/TRD. Ovid Medline, Embase, PsycINFO, Scopus and Cochrane databases were searched. Standardized mean differences were calculated using Hedges'-g to complete random effects meta-analysis. The efficacy outcomes were changes in depression outcomes for IV ketamine and IN esketamine respectively. Safety was assessed by reported adverse effects. ResultsA random effects meta-analysis of studies (n = 12) showed efficacy in reducing depression symptoms with IV ketamine (Hedges'g = 1.52 [0.98–2.22], Z = 4.23, p < 0.001) and IN esketamine (Hedges' g = 0.31 [0.18–0.44], Z = 4.53, P < 0.001) compared to control/placebo. Treatment response was observed at IV ketamine doses ≤0.2 mg/kg, >0.2–0.5 mg/kg and > 0.5 mg/kg. Higher IV ketamine doses (>0.5 mg/kg) did not lead to greater treatment response. Esketamine doses of 56–84 mg were superior to 28 mg dose. LimitationsOverall quality of evidence was low and limited by small number of studies. Publication bias was high. ConclusionsThis meta-analysis suggests that IV ketamine may be efficacious at doses as low as 0.2 mg/kg, with increasing dose response at 0.5 mg/kg, without demonstrable increased benefit at 1 mg/kg, based on a small number of studies. Efficacy for IN esketamine increases with doses above 28 mg with best response being found between 56 and 84 mg for reducing depressive symptoms.

12-month follow-up of intensive outpatient treatment for PTSD combining prolonged exposure therapy, EMDR and physical activity

BackgroundPreliminary evidence shows promising treatment outcomes at short-term follow-up for intensive posttraumatic stress disorder (PTSD) treatment, but long-term follow-up studies are sparse. This study is a sequel to a previous pilot study and open trial, set out to investigate treatment outcomes at 12-month follow-up for outpatients completing an 8-day intensive treatment for PTSD.MethodsAll patients were diagnosed with PTSD and had multiple previous psychotherapy attempts (M = 3.1). Patients were assessed at pre-treatment, post-treatment, 3- and 12-month follow-up. Of 35 treated patients, 32 (91.4%) attended the long-term follow-up assessment. The treatment programme combined prolonged exposure therapy, eye movement desensitization and reprocessing, and physical activity.ResultsThe effect sizes indicated large reductions in symptoms of PTSD, depression, anxiety, interpersonal problems, and well-being. Changes in functioning showed a small-medium effect. Results were stable across the follow-up period. The treatment response rates showed that 46–60% of patients achieved recovery with respect to PTSD symptoms, and that 44–48% no longer met diagnostic criteria for PTSD.ConclusionsTime-limited and concentrated outpatient treatment for PTSD can yield large and enduring positive outcomes. Controlled trials are needed to establish relative efficacy.Trial registrationThe study was registered in Current Research Information System In Norway (Cristin). Cristin-project-ID: 654,790.
