Reducing Depression and Suicidal Ideation Among Elder Abuse Victims Using PROTECT

Elder abuse is prevalent and often unaddressed despite poor health and mortality outcomes. One third of victims suffer from depression. ObjectiveThis study examined whether: 1) suicidal ideation is associated with victims’ demographic or abuse characteristics; 2) PROTECT psychotherapy reduces depression regardless of suicidal ideation (SI); and 3) it reduces suicidal ideation. DesignPartner agencies referred depressed victims and received PROTECT for 10 weeks. Depression severity and SI were measured at each visit. ParticipantsA sample of 158 depressed EA victims (PHQ-9 ≥ 10) without cognitive impairment (Tele-MoCA ≥ 11). InterventionPROTECT is a behavioral psychotherapy delivered in 45-minute sessions in person or remotely (phone or video) for 10 weeks. MeasuresData on demographics and abuse were collected at baseline, and depression severity (PHQ-9) and SI (PHQ-9 item 9) weekly. We examined trajectories of response to PROTECT with mixed-effects models to compare response among SI and Non-SI participants and change in SI throughout treatment. ResultsThere was no association between victims’ demographic or elder abuse characteristics and SI. PROTECT led to reduction in depression severity: the SI group showed an estimated mean improvement of 5.58 points on the PHQ-9 (95% CI: 4.11, 7.06), and non-SI group improved by 5.25 (95% CI: 4.53, 5.97) points. SI decreased over time, with 19% of participants endorsing SI at baseline and 5.7% at end of treatment. ConclusionsSuicidal ideation is equally prevalent across EA victims from different backgrounds. PROTECT can reduce depression and suicidal ideation in elder abuse victims.

Aperiodic (1/f) neural activity robustly tracks symptom severity changes in treatment-resistant depression.

A reliable physiological biomarker for Major Depressive Disorder is essential for developing and optimizing neuromodulatory treatment paradigms. This study investigates a passive electrophysiologic biomarker that tracks changes in depressive symptom severity on the order of minutes to hours. We analyze brief recordings from intracranial electrodes implanted deep in the brain during a clinical trial of deep brain stimulation for treatment-resistant depression in 5 human subjects (nfemale= 3, nmale = 2). This surgical setting allows for precise temporal and spatial sensitivity in the ventromedial prefrontal cortex, a challenging area to measure. We focused on the aperiodic slope of the power spectral density, a metric reflecting the balance of activity across all frequency bands and serving as a proxy for excitatory/inhibitory balance in the brain. Our findings demonstrate that shifts in aperiodic slope correlate with depression severity, with flatter (less negative) slopes indicating reduced depression severity. This significant correlation was observed in all N=5 subjects, particularly in the ventromedial prefrontal cortex. This biomarker offers a new way to track patient responses to Major Depressive Disorder treatment, paving the way for individualized therapies in both intracranial and non-invasive monitoring contexts.

Effectiveness of Cardiac Rehabilitation in Enhancing Clinical Outcomes for Coronary Artery Disease: A Systematic Analysis.

Cardiac rehabilitation (CR) is a structured intervention aimed at improving the clinical outcomes for patients with coronary artery disease (CAD). This systematic review assesseshow well different types of CR, such as high-intensity interval training (HIIT), moderate-intensity continuous training (MICT), Nordic walking (NW), and home-based cardiac rehabilitation (HBCR), improve exercise capacity, quality of life, and lower death and illness rates. The objective is to assess the effectiveness of cardiovascular rehabilitation programs in enhancing clinical outcomes for patients diagnosed with CAD. A comprehensive literature search was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) model across Google Scholar, EMBASE, PubMed, Medline, and web browsers. Keywords such as "cardiac rehabilitation," "coronary artery disease," "exercise testing," "VO2 peak," and "physical activity" were used in different combinations. Studies were included if they were randomized controlled trials, observational studies, or longitudinal studies published after 2013 in English, with a focus on the impact of CR on CAD. Articles were excluded if they were reviews, meta-analyses, or did not meet the keyword requirements. A total of 375 articles were initially identified with relevant citations. After further screening, 10 studies met the inclusion criteria for analysis. The studies reviewed demonstrated that all forms of CR, including HIIT, MICT, NW, and HBCR, significantly improved exercise capacity and quality of life, and reduced depression severity among CAD patients. Nordic walking showed marked improvements in functional capacity, while HIIT resulted in higher VO2 peak levels compared to moderate-intensity exercise. Home-based CR showed greater adherence rates, especially among older patients and those with strong family support. The results also highlighted the importance of individualized exercise programs to enhance adherence and outcomes. Cardiac rehabilitation is a vital component of secondary prevention in CAD patients, significantly improving clinical outcomes, including exercise capacity, quality of life, and mortality rates. The findings underscore the importance of maintaining and expanding access to CR programs and tailoring interventions to patient needs to optimize long-term health outcomes. Future research should explore the comparative effectiveness of different CR modalities and strategies to increase patient adherence.

Hair glucocorticoid levels decrease after multimodal inpatient treatment and predict therapy outcome in burnout-related depressive disorders

Objectives Hair cortisol concentration (HCC) indicates chronic stress exposure, which is a risk factor in the pathogenesis of burnout and depression. However, findings on HCC are inconsistent. Similarly, intervention studies show mixed effects on HCC. The present study aimed to shed light on these inconsistencies, by additionally considering also hair cortisone. Methods Twenty-five patients with a burnout-related depressive disorder receiving a multimodal inpatient treatment for clinical burnout and 17 matched healthy controls participated in this study. All participants provided 1 cm long hair samples at the beginning and end of the treatment. HCC and hair cortisone levels (HCNC) were determined. Meteorological data and duration of sick leave were considered as potential covariates. Burnout and depression were assessed with self-ratings, the latter also with examiner ratings. Results There were no significant group differences in glucocorticoid levels. Treatment led to a decrease in both depression severity and hair glucocorticoid concentration in inpatients, while lower HCNC in particular predicted a greater reduction in depression severity. Moreover, meteorological data and the duration of sick leave were also found to have an effect on hair glucocorticoid concentrations. Conclusions These results suggest that multimodal inpatient treatment of clinical burnout considerably reduced stress on both a psychological and biological level. In parallel, hair glucocorticoids appear to be sensitive biomarkers for the evaluation of treatment success and prediction. Examining both HCC and HCNC in intervention studies may provide clearer results than the usual examination of HCC alone.

2321 Therapeutic use of film screenings for care home residents: a scoping review

Abstract Introduction Symptoms of depression and anxiety, with and without dementia, are common in older care home residents. It is postulated that that watching films can help residents to share emotions, enhance social connectedness and engage in reminiscence. As such, films can ameliorate depression and promote well-being. This scoping review summarises the evidence for the therapeutic benefits of film-based interventions in care homes. Methods Electronic databases MEDLINE, Embase, EMCare and CINAHL were searched for quantitative and qualitative studies in English including adults aged 65 years and older in years 2005–2023. The search terms were: older adults, dementia, depression, carers, caregivers, care homes, and film. Results Five studies met our criteria: Campbell-Sills, 2006, USA; Kim, 2014, Korea; Davison et al., 2016, Australia; Bjornskov et al., 2018, Denmark; and Breckenridge et al., 2020, UK. All subjects were care home residents except for Bjornskov et al., who included 63 institutional caregivers. The number of study participants ranged from 11 to 120. There was a female predominance throughout the studies, and all residents had dementia of varying severity. Study designs included: direct comparison of participants with mood/anxiety disorder versus controls (Campbell-Sills); non-equivalent control group pretest/posttest (Kim); randomised single-blind crossover (Davison); qualitative focus-group caregiver interviews (Bjornskov); and cross-sectional observation (Breckenridge). Observation/follow up periods ranged from 6–10 weeks. Findings were as follows Campbell-Sills: residents with mood/anxiety disorders were identified by suppressing negative emotions induced by films; Kim: group reminiscence therapy using cinema increased ego integrity and reduced depression severity; Davison et al: using a personal computer platform that included films resulted in reductions in anxiety, depression and agitation; Bjornskov et al.: caregivers reported that films can evoke reminiscence; Breckenridge et al.: small-group film viewing enhanced social connectivity. Conclusions Film screenings for ageing care home residents have the potential for improving mood and encouraging social connections.

Adjunctive Intranasal Esketamine for Comorbid Treatment-Resistant Depression with Suicidal Ideation in Patients Receiving Palliative Care at a Comprehensive Cancer Center: A Case Series.

Background: The psychiatric needs of those with cancer and other advanced illnesses are becoming increasingly recognized. Ketamine is emerging as a promising treatment option for depressive disorders in psychiatric and palliative care. In the palliative care setting, its study has been hindered by lack of consistent administration routes and dosing. Intranasal (IN) esketamine (Spravato®) has recently received U.S. Food and Drug Administration (FDA) approval as an adjunctive agent for treatment-resistant depression (TRD) and major depressive disorder (MDD) with suicidal ideation (SI). Objective: We sought to offer IN esketamine to patients suffering from TRD and SI at a comprehensive cancer center. Methods: We designed and implemented a protocol to administer IN esketamine and describe three cases in which it was provided to patients with TRD and SI at a palliative care clinic in the United States. Results: Following treatment, all three patients had substantial reduction in depression severity and no further suicidalideation. These improvements were maintained for up to a year. No serious adverse events occurred. Conclusions: These cases illustrate the potential utility of IN esketamine in the palliative care setting.

Antidepressant class and concurrent rTMS outcomes in major depressive disorder: a systematic review and meta-analysis

Repetitive transcranial magnetic stimulation (rTMS) is frequently used as an adjunctive treatment with antidepressants for depression. We aimed to evaluate the clinical efficacy and safety of antidepressant classes when administered concurrently with rTMS for the management of major depressive disorder (MDD). In this systematic review and meta-analysis, MEDLINE, Embase, PsycINFO, and the Cochrane Library were searched from inception to April 12th 2024 for terms relating to medication, depression, and rTMS and appraised by 2 independent screeners. All randomized clinical trials that prospectively evaluated a specific antidepressant adjunctively with sham rTMS as a control in MDD were included. The study was registered with PROSPERO (CRD42023418435). The primary outcome measure assessed symptomatic improvement measured by formal depression scales. We used a random-effects model with pooled Standardized Mean Differences (SMDs) and log odds ratios (OR). All studies were assessed for their methodological quality and bias using the Cochrane Collaboration Risk of Bias tool version 2 (RoB2). 14 articles from 5376 identified studies were included in the systematic review and meta-analysis. There was only sufficient trial data to evaluate the effects of rTMS and combination therapy with selective serotonin reuptake inhibitors (SSRIs) and selective norepinephrine reuptake inhibitors (SNRIs). Across studies, 848 participants (mean [SD] age:41.1 [18.7] years for SSRIs, 51.8 [3.8] years for SNRIs) prospectively examined the efficacy of antidepressant medication with rTMS. Combining rTMS with SSRIs led to significantly lower depression scores, (SMD [CI] of-0.65 [-0.98,-0.31], p=0.0002, I2=66.1%), higher response (OR=0.97 [0.50, 1.44], p<0.0001, I2=25.33%) and remission rates (OR=1.04 [0.55, 1.52], p<0.0001, I2=0.00%) than medication with sham rTMS. No additive benefit was found for SNRIs with rTMS (SMD of 0.10 [-0.14, 0.34], p=0.42, I2=0.00%; OR=0.12 [-0.39, 0.62], p=0.64, I2=0.00%; OR=-0.31 [-0.90, 0.28], p=0.86, I2=39.9%). The overall risk of bias for the included studies ranged from low to high, with 1 study having a high risk of bias. The combination of rTMS with SSRIs, but not SNRIs, significantly reduced depression severity, increasing response and remission rates. Some analyses demonstrated high heterogeneity, which was influenced by an SSRI trial with a high effect size. Overall, these results suggest that not all antidepressant combination therapies are alike, and SSRIs should be considered when initiating rTMS. Donald T.

Combination of Transcranial Magnetic Stimulation and Ketamine in Treatment-Resistant Depression: A Systematic Review.

Treatment-resistant depression (TRD) is a significant challenge in psychiatric practice, affecting a substantial proportion of patients with major depressive disorder (MDD). Traditional treatment modalities often fall short, necessitating the exploration of alternative therapies. This literature review examines the combined use of Transcranial Magnetic Stimulation (TMS) and ketamine in treating TRD. The objectiveof this study is toevaluate the efficacy, safety, and potential synergies of combining TMS and ketamine in the treatment of TRD. A comprehensive literature search was conducted using PubMed and Google Scholar databases from 2014 to 2024. The search terms included combinations of "Transcranial Magnetic Stimulation," "Ketamine," "Depression," "Major Depressive Disorder," "Treatment-Resistant Depression," and "Combination." After screening for relevance and applying inclusion and exclusion criteria, six studies were selected for review, including three case reports, a retrospective study, a pilot study, and a review study. The selected studies demonstrated that the combination of TMS and ketamine resulted in substantial and sustained improvement in depressive symptoms for patients with TRD. Case reports and retrospective studies highlighted significant reductions in depression severity and improvements in psychosocial functioning. The combination therapy showed a higher efficacy compared to monotherapies of either TMS or ketamine alone. Notably, adverse effects were generally mild and transient, with no severe adverse events reported in most studies. In conclusion, the combination of TMS and ketamine presents a promising treatment modality for patients with TRD, offering significant improvements in depressive symptoms and better outcomes compared to traditional monotherapies. However, the heterogeneity in study designs and small sample sizes underline the need for larger, randomized controlled trials to establish standardized protocols and further validate these findings.

The efficacy of automated feedback after internet-based depression screening (DISCOVER): an observer-masked, three-armed, randomised controlled trial in Germany

Despite the availability of effective treatments, most depressive disorders remain undetected and untreated. Internet-based depression screening combined with automated feedback of screening results could reach people with depression and lead to evidence-based care. We aimed to test the efficacy of two versions of automated feedback after internet-based screening on depression severity compared with no feedback. DISCOVER was an observer-masked, three-armed, randomised controlled trial in Germany. We recruited individuals (aged ≥18 years) who were undiagnosed with depression and screened positive for depression on an internet-based self-report depression rating scale (Patient Health Questionnaire-9 [PHQ-9] ≥10 points). Participants were randomly assigned 1:1:1 to automatically receive no feedback, non-tailored feedback, or tailored feedback on the depression screening result. Randomisation was stratified by depression severity (moderate: PHQ-9 score 10-14 points; severe: PHQ-9 score ≥15 points). Participants could not be masked but were kept unaware of trial hypotheses to minimise expectancy bias. The non-tailored feedback included the depression screening result, a recommendation to seek professional diagnostic advice, and brief general information about depression and its treatment. The tailored feedback included the same basic information but individually framed according to the participants' symptom profiles, treatment preferences, causal symptom attributions, health insurance, and local residence. Research staff were masked to group allocation and outcome assessment as these were done using online questionnaires. The primary outcome was change in depression severity, defined as change in PHQ-9 score 6 months after random assignment. Analyses were conducted following the intention-to-treat principle for participants with at least one follow-up visit. This trial was registered at ClinicalTrials.gov, NCT04633096. Between Jan 12, 2021, and Jan 31, 2022, 4878 individuals completed the internet-based screening. Of these, 1178 (24%) screened positive for depression (mean age 37·1 [SD 14·2] years; 824 [70%] woman, 344 [29%] men, and 10 [1%] other gender identity). 6 months after random assignment, depression severity decreased by 3·4 PHQ-9 points in the no feedback group (95% CI 2·9-4·0; within-group d 0·67; 325 participants), by 3·5 points in the non-tailored feedback group (3·0-4·0; within-group d 0·74; 319 participants), and by 3·7 points in the tailored feedback group (3·2-4·3; within-group d 0·71; 321 participants), with no significant differences among the three groups (p=0·72). The number of participants seeking help for depression or initiating psychotherapy or antidepressant treatment did not differ among study groups. The results remained consistent when adjusted for fulfilling the DSM-5-based criteria for major depressive disorder or subjective belief of having a depressive disorder. Negative effects were reported by less than 1% of the total sample 6 months after random assignment. Automated feedback following internet-based depression screening did not reduce depression severity or prompt sufficient depression care in individuals previously undiagnosed with but affected by depression.

The Application of Cohen’s Stress-Buffering Model for Weight Bias Internalization in Prebariatric Patients

Introduction: Weight bias internalization (WBI) is associated with reduced psychological well-being in individuals with obesity. The aim of this study was to investigate the application of Cohen’s stress-buffering model of social support for WBI on well-being in patients presenting for bariatric surgery. Methods: In N = 804 adult prebariatric patients, WBI, social support, depression severity, health-related quality of life (HRQOL), and self-esteem were assessed by self-report questionnaires. Structural Equation Modeling was applied to test for direct associations between social support and well-being and for a buffering effect of social support on the relationship between WBI and well-being. Results: After controlling for age, sex, and body mass index, greater social support was directly associated with reduced depression severity and increased self-esteem, but not with increased HRQOL. Contrary to Cohen’s stress-buffering model, social support showed no moderating effects on the association between WBI and depression severity, HRQOL, and self-esteem. Conclusion: These cross-sectional results may indicate that greater social support is associated with improved well-being, supporting it as a potential coping resource in bariatric surgery. Given the absence of supporting evidence for the buffering effect in the present study, future prospective research may reevaluate the existence of a moderating effect of social support and investigate whether support-focused interventions improve psychological well-being.

Analyzing fractal dimension in electroconvulsive therapy: Unraveling complexity in structural and functional neuroimaging

BackgroundNumerous studies show that electroconvulsive therapy (ECT) induces hippocampal neuroplasticity, but findings are inconsistent regarding its clinical relevance. This study aims to investigate ECT-induced plasticity of anterior and posterior hippocampi using mathematical complexity measures in neuroimaging, namely Higuchi's fractal dimension (HFD) for fMRI time series and the fractal dimension of cortical morphology (FD-CM). Furthermore, we explore the potential of these complexity measures to predict ECT treatment response. MethodsTwenty patients with a current depressive episode (16 with major depressive disorder and 4 with bipolar disorder) underwent MRI-scans before and after an ECT-series. Twenty healthy controls matched for age and sex were also scanned twice for comparison purposes. Resting-state fMRI data were processed, and HFD was computed for anterior and posterior hippocampi. Group-by-time effects for HFD in anterior and posterior hippocampi were calculated and correlations between HFD changes and improvement in depression severity were examined. For FD-CM analyses, we preprocessed structural MRI with CAT12′s surface-based methods. We explored group-by-time effects for FD-CM and the predictive value of baseline HFD and FD-CM for treatment outcome. ResultsPatients exhibited a significant increase in bilateral hippocampal HFD from baseline to follow-up scans. Right anterior hippocampal HFD increase was associated with reductions in depression severity. We found no group differences and group-by-time effects in FD-CM. After applying a whole-brain regression analysis, we found that baseline FD-CM in the left temporal pole predicted reduction of overall depression severity after ECT. Baseline hippocampal HFD did not predict treatment outcome. ConclusionThis study suggests that HFD and FD-CM are promising imaging markers to investigate ECT-induced neuroplasticity associated with treatment response.

Student mental health during Summer 2022 research experiences for undergraduates (REUs): Mentorship, remote engagement, and COVID-19

Objective: We examined how mentorship, remote participation, and COVID-19 challenges were associated with the mental health of college students participating in summer research programs. Participants: Participants were students participating in 78 National Science Foundation (NSF) Research Experiences for Undergraduate (REU) Sites during Summer 2022 (n = 516 students). Methods: We used multivariable generalized estimating equations that account for clustering by REU Site. Results: Students with more competent mentors had reduced depression severity. Students who spent ≥25% of their time doing remote research or ≥25% of their time in remote meetings and workshops had greater depression severity. Remote research was also associated with anxiety severity. Having a COVID-19 challenge that impacted students’ research experience was associated with increases in depression and anxiety severity. Conclusions: Results suggest potential interventions: implement strategies to boost mentor competency and scaffold a support system into summer research programs to enhance student wellbeing. Additional research on remote engagement is needed.

Study protocol: exercise training for treating major depressive disorder in multiple sclerosis

BackgroundMajor depressive disorder (MDD) is prevalent, yet sub-optimally treated among persons with multiple sclerosis (MS). We propose that exercise training may be a promising approach for treating depression in persons with MS who have MDD. Our primary hypothesis predicts a reduction in depression severity immediately after an exercise training intervention compared with minimal change in an attention control condition, and the reduction will be maintained during a follow-up period.MethodsThis study involves a parallel-group, assessor-blinded RCT that examines the effect of a 4-month home-based exercise training intervention on depression severity in a sample of persons with MS who have MDD based on the MINI International Neuropsychiatric Interview. The primary outcomes of depression severity are the Patient Health Questionnaire-9 and Hamilton Depression Rating Scale. Participants (N = 146) will be recruited from within 200 miles of the University of Illinois at Chicago and randomized (1:1) into either a home-based exercise training condition or control condition with concealed allocation. The exercise training and social-contact, attention control (i.e., stretching) conditions will be delivered remotely over a 4-month period and supported through eight, 1:1 Zoom-based behavioral coaching sessions guided by social-cognitive theory and conducted by persons who are uninvolved in screening, recruitment, random assignment, and outcome assessment. We will collect outcome data at 0, 4 and 8 months using treatment-blinded assessors, and data analyses will involve intent-to-treat principles.DiscussionIf successful, the proposed study will provide the first Class I evidence supporting a home-based exercise training program for treating MDD in persons with MS. This is critical as exercise training would likely have positive secondary effects on symptoms, cognition, and quality of life, and provide a powerful, behavioral approach for managing the many negative outcomes of MDD in MS. The program in the proposed research is accessible and scalable for broad treatment of depression in MS, and provides the potential for integration in the clinical management of MS.Trial registrationThe trial was registered on September 10, 2021 at clinicaltrials.gov with the identifier NCT05051618. The registration occurred before we initiated recruitment on June 2, 2023

Psychological flexibility as a mechanism of change in psilocybin-assisted therapy for major depression: results from an exploratory placebo-controlled trial

Several phase II studies have demonstrated that psilocybin-assisted therapy shows therapeutic potential across a spectrum of neuropsychiatric conditions, including major depressive disorder (MDD). However, the mechanisms underlying its often persisting beneficial effects remain unclear. Observational research suggests that improvements in psychological flexibility may mediate therapeutic effects. However, no psychedelic trials to date have substantiated this finding in a clinical sample. In an exploratory placebo-controlled, within-subject, fixed-order study, individuals with moderate to severe MDD were administered placebo (n = 19) followed by psilocybin (0.3 mg/kg) (n = 15) 4 weeks later. Dosing sessions were embedded within a manualized psychotherapy that incorporated principles of Acceptance and Commitment Therapy. Depression severity, psychological flexibility, mindfulness, and values-congruent living were measured over a 16-weeks study period. Psychological flexibility, several facets of mindfulness, and values-congruent living significantly improved following psilocybin and were maintained through week 16. Additionally, improvements in psychological flexibility and experiential acceptance were strongly associated with reductions in depression severity following psilocybin. These findings support the theoretical premise of integrating psilocybin treatment with psychotherapeutic platforms that target psychological flexibility and add to emerging evidence that increasing psychological flexibility may be an important putative mechanism of change in psilocybin-assisted therapy for MDD and potentially, other mental health conditions.

Is a brief mindfulness ecological momentary intervention more efficacious than a self-monitoring app for social anxiety disorder? A randomized controlled trial

Despite their proliferation, limited knowledge exists regarding possible benefits of brief mindfulness ecological momentary interventions (MEMIs) for social anxiety disorder (SAD). Propositions that MEMIs could alleviate SAD symptoms and related clinical outcomes remain untested. This trial evaluated a 14-day MEMI for SAD. Participants with self-reported SAD were randomized to MEMI (n = 96) or self-monitoring app (SM; n = 95). Whereas MEMI instructed mindfulness exercises, SM prompted only self-monitoring five times daily for 14 days. Participants completed state-level self-reports of depression, anxiety, and mindfulness pre-post-mindfulness practice and SAD symptoms, worry, depression severity, repetitive negative thinking, and trait mindfulness at pre-randomization, post-intervention, and 1-month follow-up (1MFU). Hierarchical linear modeling was conducted. The MEMI yielded statistically significantly larger improvements in momentary depression, anxiety, and mindfulness (Cohen's d = −0.10–0.11). Although no between-group effects emerged in alleviating SAD fear and avoidance, excessive worry, depression severity, repetitive negative thinking, and trait mindfulness (−0.13–0.15), within-group effects were significantly small-to-large from pre-post and pre-1MFU (−4.62–0.67). A significant reduction in depression severity occurred in MEMI (−0.63–−0.60) but not SM (−0.31–−0.29). Brief MEMI and SM yielded nondifferent sustained effects on SAD, comorbid symptoms, and risk factors, highlighting its potential value within stepped-care delivery settings.

Gastrointestinal Microbiota & Symptoms of Depression and Anxiety in Anorexia Nervosa-A Re-Analysis of the MICROBIAN Longitudinal Study.

The microbiota-gut-brain axis may play a role in the pathophysiology of anorexia nervosa (AN). Here, the relationship between the gastrointestinal microbiota and symptoms of depression, anxiety, and eating disorder pathology in patients with AN before (n = 55) and after weight restoration (n = 44) was investigated by reanalyzing the data of the MICROBIAN study. The gastrointestinal microbiota was analyzed using 16S rRNA amplicon sequencing. Symptoms of anxiety disorder, depression, and the severity of the eating disorder were measured by validated questionnaires. All analyses were adjusted for the body mass index (BMI). Several significant findings between psychological parameters and the gastrointestinal microbiota were not evident after controlling for the BMI. No differences in alpha and beta diversity between groups of higher and lower symptom severity levels for depression and anxiety were found. Positive associations between species of Blautia and Ruminococcus and depression symptoms, and between the phylum Firmicutes and anxiety symptoms were observed after rehabilitation, respectively. A positive correlation was found between propionate and acetate levels and the reduction of depression severity during inpatient treatment. Accounting for the weight status when analyzing the relationship between psychological parameters and the gastrointestinal microbiota in patients with underweight is important since the BMI may be the driver for many observed changes.

Can routine assessment of older people's mental health lead to improved outcomes: A regression discontinuity analysis.

To assess whether case finding for depression among people aged 65 and above improves mental health. Opportunistic evaluation using a regression discontinuity analysis with data from a randomised controlled trial. The REFORM trial, a falls prevention study that recruited patients from NHS podiatry clinics. 1010 community-dwelling adults over the age of 65 with at least one risk factor for falling (recent previous fall or fear of falling). Letter sent to patient's General Practitioner if they scored 10 points or above on the 15-item Geriatric Depression Scale (GDS-15) informing them of the patient's risk of depression. GDS-15 score six months after initial completion of GDS-15. 895 (88.6%) of the 1010 participants randomised into REFORM had a valid baseline and six-month GDS-15 score and were included in this study. The mean GDS-15 baseline score was 3.5 (SD 3.0, median 3.0, range 0-15); 639 (71.4%) scored 0-4, 204 (22.8%) scored 5-9 indicating mild depression, and 52 (5.8%) scored 10 or higher indicating severe depression. At six months follow-up, those scoring 10 points or higher at baseline had, on average, a reduction of 1.08 points on the GDS-15 scale (95% confidence interval -1.83 to -0.33, p = 0.005) compared to those scoring less than 10, using the simplest linear regression model. Case finding of depression in podiatry patients based on a GDS-15 score of 10 or more followed by a letter to their General Practitioner significantly reduced depression severity. Whether this applies to all older patients in primary care is unknown. Further research is required to confirm these findings. Regression discontinuity analyses could be prespecified and embedded within other existing research studies.

Family intimacy and adaptability and non-suicidal self-injury: a mediation analysis

BackgroundCurrent research has been focusing on non-suicidal self-injury (NSSI) behaviors among adolescents with depression. Although family intimacy and adaptability are considered protective factors for NSSI, evidence supporting this relationship is lacking.ObjectiveThis study aims to examine the mechanisms operating in the relationship between family intimacy and adaptability and NSSI behaviors among adolescents.MethodsA self-administered general demographic information questionnaire, the Behavioral Functional Assessment Scale for Non-Suicidal Self-Injury, the Family Intimacy and Adaptability Scale, the Connor-Davidson Resilience Scale, and the Self-Assessment of Depression Scale were distributed among adolescents with depression in three tertiary hospitals in Jiangsu Province.ResultsThe relationship between family intimacy and adaptability and NSSI was assessed among 596 adolescents with depression. The results revealed the following: (1) Family intimacy and adaptability were negatively correlated with NSSI behavior. (2) Psychological resilience and depression levels acted as chain mediators in the relationship between family intimacy and adaptability and NSSI behavior.ConclusionsEnhancing psychological resilience, controlling depressive symptoms, and reducing depression severity among adolescents by improving their family intimacy and adaptability are conducive to preventing and mitigating their NSSI behaviors.

Clinical effectiveness of patient-targeted feedback following depression screening in general practice (GET.FEEDBACK.GP): an investigator-initiated, prospective, multicentre, three-arm, observer-blinded, randomised controlled trial in Germany

Screening for depression in primary care alone is not sufficient to improve clinical outcomes. However, targeted feedback of the screening results to patients might result in beneficial effects. The GET.FEEDBACK.GP trial investigated whether targeted feedback of the depression screening result to patients, in addition to feedback to general practitioners (GPs), leads to greater reductions in depression severity than GP feedback alone or no feedback. The GET.FEEDBACK.GP trial was an investigator-initiated, multicentre, three-arm, observer-blinded, randomised controlled trial. Depression screening was conducted electronically using the Patient Health Questionnaire-9 (PHQ-9) in 64 GP practices across five regions in Germany while patients were waiting to see their GP. Currently undiagnosed patients (aged ≥18 years) who screened positive for depression (PHQ-9 score ≥10), were proficient in the German language, and had a personal consultation with a GP were randomly assigned (1:1:1) into a group that received no feedback on their depression screening result, a group in which only the GP received feedback, or a group in which both GP and patient received feedback. Randomisation was stratified by treating GP and PHQ-9 depression severity. Trial staff were masked to patient enrolment and study group allocation and GPs were masked to the feedback recieved by the patient. Written feedback, including the screening result and information on depression, was provided to the relevant groups before the consultation. The primary outcome was PHQ-9-measured depression severity at 6 months after randomisation. An intention-to-treat analysis was conducted for patients who had at least one follow-up visit. This study is registered at ClinicalTrials.gov (NCT03988985) and is complete. Between July 17, 2019, and Jan 31, 2022, 25 279 patients were approached for eligibility screening, 17 150 were excluded, and 8129 patients completed screening, of whom 1030 (12·7%) screened positive for depression. 344 patients were randomly assigned to receive no feedback, 344 were assigned to receive GP-targeted feedback, and 339 were assigned to receive GP-targeted plus patient-targeted feedback. 252 (73%) patients in the no feedback group, 252 (73%) in the GP-targeted feedback group, and 256 (76%) in the GP-targeted and patient-targeted feedback group were included in the analysis of the primary outcome at 6 months, which reflected a follow-up rate of 74%. Gender was reported as female by 637 (62·1%) of 1025 participants, male by 384 (37·5%), and diverse by four (0·4%). 169 (16%) of 1026 patients with available migration data had a migration background. Mean age was 39·5 years (SD 15·2). PHQ-9 scores improved for each group between baseline and 6 months by -4·15 (95% CI -4·99 to -3·30) in the no feedback group, -4·19 (-5·04 to -3·33) in the GP feedback group, and -4·91 (-5·76 to -4·07) in the GP plus patient feedback group, with no significant difference between the three groups (global p=0·13). The difference in PHQ-9 scores when comparing the GP plus patient feedback group with the no feedback group was -0·77 (-1·60 to 0·07, d=-0·16) and when comparing with the GP-only feedback group was -0·73 (-1·56 to 0·11, d=-0·15). No increase in suicidality was observed as an adverse event in either group. Providing targeted feedback to patients and GPs after depression screening does not significantly reduce depression severity compared with GP feedback alone or no feedback. Further research is required to investigate the potential specific effectiveness of depression screening with systematic feedback for selected subgroups. German Innovation Fund.

Psilocybin-assisted psychotherapy for treatment resistant depression: A randomized clinical trial evaluating repeated doses of psilocybin

Psilocybin-assisted psychotherapy (PAP) has been associated with antidepressant effects. Trials to date have typically excluded participants with complex presentations. Our aim was to determine the feasibility of PAP in a complex population, including high levels of treatment resistance in major depressive and bipolar disorder and patients with baseline suicidality and significant comorbidity. We also evaluated flexible repeated doses over a 6-month period. Adults with treatment-resistant depression as part of major depressive or bipolar II disorder without psychosis or a substance use disorder were eligible to participate. Subjects were randomized to immediate treatment or waitlist control, with all eventually receiving PAP. Participants had one, two, or three psilocybin sessions with a fixed doseof 25mg. Each dose was accompanied by preparation and integration psychotherapy sessions. Acceptability, safety, tolerability, and efficacy were evaluated (this study was registered at ClinicalTrials.gov: NCT05029466). Participants were randomized to immediate treatment (n=16) or delayed treatment (n= 14). 29/30 were retained to the week-2 primary endpoint. Adverse events were transient, with no serious adverse events. Greater reductions in depression severity as measured by the Montgomery-Åsberg Depression Rating Scale (MADRS) were observed in the immediate treatment arm compared to the waitlist period arm with a large hedge's g effect size of 1.07 (p<0.01). Repeated doses were associated with further reductions in MADRS scores compared to baseline. PAP was feasible in complex patients with preliminary antidepressant efficacy and adequate safety and tolerability. Repeated doses were associated with greater reductions in depression severity.
