Assessing Suicide Prevention Apps' Responsiveness to Help-Seeking Needs of Individuals Connected with Mental Health Services.

This paper maps suicide help-seeking needs identified in the literature, on to the features and functionalities of suicide prevention mobile apps using the adapted ecological model, thereby revealing existing gaps between help-seeking needs and available apps. This paper builds upon previous work by our team, which includes 1) a rapid scoping review aimed at identifying barriers and facilitators of help-seeking related to suicide within psychiatric populations, and 2) a review of suicide prevention apps, including a content analysis of app features and functionalities.

Self-Harm by Nurses and Midwives - A Study of Hospital Presentations.

Background: Nursing professionals are an occupational group at increased risk of suicide, but little is known about self-harm in this population. Aims: To investigate the characteristics of nurses and midwives who present to hospital following self-harm. Method: We used data from the Oxford Monitoring System for Self-Harm to identify nurses and midwives who presented to the general hospital in Oxford during 2010-2020 following an episode of self-harm and received a psychosocial assessment. Results: During the eleven-year study period, 107 presentations of self-harm involving 81 nurses and midwives were identified. Self-poisoning was the most common self-harm method (71.6%), with antidepressants and paracetamol most frequently involved. Many had consumed alcohol before (43.8%) or during (25.3%) the self-harm act. Some individuals had high or very high suicide intent scores (22/70, 31.4%). Common problems preceding self-harm included problems with a partner (46.9%), psychiatric disorder (29.6%), and problems with employment (27.2%), family (24.7%), and alcohol (23.5%). A range of aftercare options were offered following presentation. Limitations: This study was limited to data from a single hospital. Conclusion: Prevention and management of self-harm within this occupational group requires preventative strategies and availability of interventions addressing the range of factors that may contribute to self-harm, especially relationship problems, psychiatric disorders, employment problems, and alcohol misuse.

Suicidal thoughts and behaviours among student nurses and midwives: A systematic review.

AIM: To synthesize research investigating suicide, suicide attempts, self-harm and suicide ideation in nursing and midwifery students, a group of interest due to high rates of suicide among qualified nurses. Specific areas of interest for this review included prevalence, factors which may contribute to or mitigate risk and suicide prevention interventions. DESIGN: A systematic review was conducted, and Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed. DATA SOURCES: Three electronic databases were searched, and additional articles identified using hand-searching. Studies were included if they examined suicide, suicide attempts, self-harm or suicide ideation in nursing or midwifery students. REVIEW METHODS: Studies were deduplicated and assessed for inclusion. Data from included studies were extracted, quality of studies assessed and data synthesized, informed by study focus, design and assessed quality. RESULTS: About 46 studies of largely moderate to low quality were identified. A high-quality study demonstrated increased risk of suicide in Swedish female nursing students, and increased risk of self-harm in nursing students of both sexes. Prevalence of suicide ideation did not appear to differ across course year, or between nursing students and students on other programmes. Psychiatric conditions, particularly depression, were associated with suicide ideation. Three studies related to suicide prevention interventions were identified. Integration of wellness initiatives into the curriculum and peer support were preferred interventions among nursing students and teaching staff. CONCLUSIONS: To understand the extent of suicide and self-harm among nursing and midwifery students there is a need for further epidemiological research stratified by programme of study. To develop prevention interventions and initiatives for nursing students, high-quality longitudinal studies should examine characteristics associated with suicide and self-harm. IMPACT: Current findings suggest interventions could include support for students experiencing mental health difficulties, foster peer support, and help develop wellness. No patient or public contribution.

Experiences of clinical staff who work with patients who self-harm by ligature: An exploratory survey of inpatient mental health service staff.

WHAT IS KNOWN ON THE SUBJECT: Self-harm by ligature is common within inpatient mental healthcare settings and is a dangerous method of self-harm. Most fatal and non-fatal suicidal behaviours in inpatient settings are a result of ligature use. There is a lack of research which has explored the experiences of staff members who work within inpatient settings where patients may self-harm by ligature. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE: Key issues related to self-harm by ligature reported by staff included (1) understaffing increasing risk of ligature incidents, (2) spreading of self-harm by ligature within inpatient settings and (3) negative attitudes of staff related to patients who self-harm by ligature. Working with self-harm by ligature can have negative impacts on staff's personal (e.g. fear of blame) and professional lives (e.g. increased cautiousness). Many staff members currently feel underprepared by training related to working with self-harm by ligature, and unsupported after responding to a ligature incident. WHAT ARE THE IMPLICATIONS FOR PRACTICE: Training about self-harm by ligature needs to be improved and be accessible for all inpatient mental healthcare staff. Training should be coproduced, and could include practical components, education on potential reasons for self-harm, and acknowledgement of the emotional impact on staff. Support for staff members who respond to ligature incidents should be available for all staff members who respond to self-harm by ligature incidents. Stigma associated with accessing support should be challenged, alongside blame cultures within the workplace. ABSTRACT: INTRODUCTION: Self-harm by ligature is a common form of self-harm within inpatient mental health services in England, where most suicides within inpatient settings involve hanging or suffocation. However, little research has examined the experiences of staff members working with this method of self-harm. AIM: We explored the experiences of clinical staff who work with patients who self-harm by ligature. METHOD: A staff survey was developed and disseminated to clinical staff working in inpatient settings in England. Quantitative data were analysed using descriptive statistics, and qualitative data using the framework approach. The study was STROBE checklist compliant. RESULTS: 275 staff members participated. Challenges most frequently reported about working with self-harm by ligature included understaffing (210, 76.6%), spreading of ligature incidents (198, 72.8%) and negative attitudes held by clinical staff towards such patients (185, 68.5%). Participants' responses indicated that this work could have significant impacts on their professional and personal lives. Staff often reported inadequate training and lack of preparedness, alongside insufficient support opportunities following ligature incidents. DISCUSSION: Staff had a diverse range of professional and personal experiences and identified multiple challenges associated with working with patients who have self-harmed by ligature. IMPLICATIONS FOR PRACTICE: There is a need to improve accessibility, format and content of training and support for staff working within inpatient settings where patients may self-harm by ligature.

Suicide, self-harm, and suicide ideation in nurses and midwives: A systematic review of prevalence, contributory factors, and interventions.

BACKGROUND: Nurses have been identified as an occupational group at increased risk of suicide. This systematic review examines the prevalence of, and factors influencing, suicide and related behaviours among nurses and midwives (PROSPERO pre-registration CRD42021270297). METHODS: MEDLINE, PsycINFO, and CINAHL were searched. Articles published from 1996 onwards exploring suicidal thoughts and behaviours among nurses and midwives were included. Quality of included studies was assessed. Articles were subjected to narrative synthesis informed by suicide data examined, study design, and quality. PRISMA guidelines were followed. RESULTS: A total of 100 studies were eligible for inclusion in the review. Articles examining suicide exclusively among midwives were absent from the literature. Several studies confirmed that nursing professionals, especially female, are at increased risk of suicide, particularly by self-poisoning. Factors contributing to risk include psychiatric disorders, alcohol and substance misuse, physical health problems, and occupational and interpersonal difficulties. In studies of non-fatal suicidal behaviours, including during the COVID-19 pandemic, psychiatric, psychological, physical and occupational factors were contributory. There has been little investigation of interventions for prevention of suicide in nurses. LIMITATIONS: Only articles published in English language were reviewed. CONCLUSIONS: The findings highlight the risk of suicide in nurses. They also show a combination of factors contribute to suicide and non-fatal suicidal behaviour in nurses, with psychiatric, psychological, physical health, occupational and substance misuse (especially alcohol) problems being particularly important. The limited evidence regarding prevention measures indicates a major need to develop primary and secondary interventions for this at-risk occupational group, for example, education regarding enhancing wellbeing and safe alcohol use, alongside accessible psychological support.

Relationship between baseline cognition and 18-month treatment response in bipolar disorder.

BACKGROUND: To date, few studies have examined baseline cognitive function as a predictor of clinical outcome following treatment in bipolar disorder (BD). The aim of this analysis was therefore to examine the relationship between baseline cognitive function and treatment outcome in a sample of young adults with BD receiving Interpersonal Social Rhythm Therapy (IPSRT) or Specialist Supportive Care (SSC) with adjunctive pharmacotherapy. METHODS: Eighty-six BD patients underwent baseline cognitive testing and completed 18 months of IPSRT or SCC. Univariate analyses examined the relationship between baseline cognitive function (global and individual cognitive domains) and change in mood symptom burden, and psychosocial functioning, from baseline to treatment-end. RESULTS: Baseline global cognition was not predictive of change in mood symptom burden over 18 months of treatment. However, poorer baseline psychomotor speed performance was associated with less improvement in mood symptom burden at treatment-end. Neither baseline global cognition nor individual cognitive domain scores were associated with change in psychosocial functioning. LIMITATIONS: Due to the exploratory nature of the study, correction was not made for multiple comparisons. Data was obtained from a relatively small sample and has been the subject of prior analysis, thereby increasing the likelihood of chance findings. CONCLUSION: Although global cognition was not associated with outcome, when examining individual domains, poorer baseline psychomotor speed predicted less change in mood symptom burden following 18-months of psychotherapy and pharmacotherapy. This suggests that pre-treatment measures of psychomotor speed may help to identify those who require additional, and more targeted, intervention. Further large-scale research is required.

News reporting of suicide in nurses: A content analysis study.

Media impact on suicide is well-established. Groups at heightened risk of suicide, such as nurses, may be particularly influenced by poor news reporting. This study aimed to examine UK newspaper reporting of suicide of nurses and student nurses, including during the COVID-19 pandemic. Print and online newspaper reports about suicide in nurses (including students) published in the UK between January 2018 and August 2021 were obtained and data extracted for analysis in collaboration with Samaritans' media advisory team. Content and quality of newspaper reports were examined using a content analysis approach. The study was compliant with the STROBE checklist. Nurse or student nurse suicides were reported in 134 articles, including 50 individual suicides. Most articles were acceptable against Samaritans' media guidelines. However, common problems included absence of signposting to support organizations and lack of suicide prevention messages. A minority of articles included methods of suicide within article headlines (18, 13.4%) and sensationalist or romanticizing language (14, 10.7%). Most contained occupation-related content. Many named the individual's specific hospital or university and a substantial proportion included occupation-related images. Working on the frontline was the most reported link between COVID-19 and nurse suicide. While reporting on suicide among nurses and students was largely acceptable, quality of reporting was variable. Occupation was often discussed, and most articles published during COVID-19 linked suicide to the pandemic. The research findings can help shape guidance on reporting of suicide in specific professions and occupations, including nursing, to encourage responsible reporting and reduce inadvertent promotion of suicide.

Attitudes towards the integration of smoking cessation into lung cancer screening in the United Kingdom: A qualitative study of individuals eligible to attend.

INTRODUCTION: There is limited research exploring how smoking cessation treatment should be implemented into lung cancer screening in the United Kingdom. This study aimed to understand attitudes and preferences regarding the integration of smoking cessation support within lung cancer screening from the perspective of those eligible. METHODS: Thirty-one lung cancer screening eligible individuals aged 55-80 years with current or former smoking histories were recruited using community outreach and social media. Two focus groups (three participants each) and 25 individual telephone interviews were conducted. Data were analysed using the framework approach to thematic analysis. RESULTS: Three themes were generated: (1) bringing lung cancer closer to home, where screening was viewed as providing an opportunity to motivate smoking cessation, depending on perceived personal risk and screening result; (2) a sensitive approach to cessation with the uptake of cessation support considered to be largely dependent on screening practitioners' communication style and expectations of stigma and (3) creating an equitable service that focuses on ease of access as a key determinant of uptake, where integrating cessation within the screening appointment may sustain increased quit motivation and prevent loss to follow-up. CONCLUSIONS: The integration of smoking cessation into lung cancer screening was viewed positively by those eligible to attend. Screening appointments providing personalized lung health information may increase cessation motivation. Services should proactively support participants with possible fatalistic views regarding risk and decreased cessation motivation upon receiving a good screening result. To increase engagement in cessation, services need to be person-centred. PATIENT OR PUBLIC CONTRIBUTION: This study has included patient and public involvement throughout, including input regarding study design, research materials, recruitment strategies and research summaries.

The Impact of Morbidity and Disability on Attendance at Organized Breast Cancer-Screening Programs: A Systematic Review and Meta-Analysis.

Individuals with morbidity experience worse breast cancer outcomes compared with those without. This meta-analysis assessed the impact of morbidity on breast cancer-screening attendance and subsequent early detection (PROSPERO pre-registration CRD42020204918). MEDLINE, PsychInfo, and CINAHL were searched. Included articles published from 1988 measured organized breast-screening mammography attendance using medical records by women with morbidity compared with those without. Morbidities were assigned to nine diagnostic clusters. Data were pooled using random-effects inverse meta-analyses to produce odds ratios (OR) for attendance. 25 study samples (28 articles) were included. Data were available from 17,755,075 individuals, including at least 1,408,246 participants with one or more conditions;16,250,556 had none. Individuals with any morbidity had lower odds of attending breast screening compared with controls [k = 25; OR, 0.76; 95% confidence interval (CI), 0.70-0.81; P = <0.001; I2 = 99%]. Six morbidity clusters had lower odds of attendance. The lowest were for neurological, psychiatric, and disability conditions; ORs ranged from 0.45 to 0.59 compared with those without. Morbidity presents a clear barrier for breast-screening attendance, exacerbating health inequalities and, includes a larger number of conditions than previously identified. Consensus is required to determine a standardized approach on how best to identify those with morbidity and determine solutions for overcoming barriers to screening participation based on specific morbidity profiles.

What do young women below national screening age in England think about cervical cancer and cervical screening? A qualitative study.

AIMS AND OBJECTIVES: To explore what women aged below the national screening age in the UK know and think about cervical cancer and cervical screening. BACKGROUND: The efficacy of cervical cancer screening is well established. However, cervical screening attendance in the United Kingdom has decreased, with especially low rates at the first screening opportunity at age 25. Research has not yet explored knowledge and beliefs underpinning young women's intention to screen before first screening invitation. DESIGN: Qualitative exploratory study. METHODS: Qualitative email interviews were undertaken with 16 participants, using questions derived from the Health Belief Model. Data were analysed using template analysis. The COREQ were followed. RESULTS: Analysis generated three themes; (1) Learning about cervical cancer and cervical screening: sources of information and (missed) opportunities; (2) Young women know screening is important - but they don't always know why; (3) Screening intentions: a cost/benefit analysis of the available information. CONCLUSIONS: Young women had varied knowledge and beliefs about cervical cancer and screening which were underpinned by several sources of information available to them. Most women expressed an intention to attend screening when invited; however, some participants were unsure, with low screening-based knowledge and low perceived susceptibility of cervical cancer identified as key barriers. Social media, familial interactions and interventions within education were highlighted as being suited to interventions aimed at increasing cervical cancer- and screening-based knowledge in young women. RELEVANCE TO CLINICAL PRACTICE: Findings suggest that women below screening age could be better informed about cervical cancer and screening. Tailored interventions addressing common concerns and misconceptions around screening may be acceptable to young women and could help to promote screening attendance at first invitation.

A randomised controlled trial of psychotherapy and cognitive remediation to target cognition in mood disorders.

OBJECTIVE: To examine the impact of a treatment package combining Interpersonal and Social Rhythm Therapy (IPSRT) and cognitive remediation (CR), vs IPSRT alone, on cognition, functioning, and mood disturbance outcomes in mood disorders. METHODS: A pragmatic randomised controlled trial in adults with bipolar disorder (BD) or major depressive disorder (MDD), recently discharged from mental health services in Christchurch, New Zealand, with subjective cognitive difficulties. Individuals were randomised to a 12-month course of IPSRT with CR (IPSRT-CR), or without CR (IPSRT). In IPSRT-CR, CR was incorporated into therapy sessions from approximately session 5 and continued for 12 sessions. The primary outcome was change in Global Cognition (baseline to 12 months). RESULTS: Sixty-eight individuals (BD n = 26, MDD n = 42; full/partial remission n = 39) were randomised to receive IPSRT-CR or IPSRT (both n = 34). Across treatment arms, individuals received an average of 23 IPSRT sessions. Change in Global Cognition did not differ between arms from baseline to treatment-end (12 months). Psychosocial functioning and longitudinal depression symptoms improved significantly more in the IPSRT compared with IPSRT-CR arm over 12 months, and all measures of functioning and mood symptoms showed moderate effect size differences favouring IPSRT (0.41-0.60). At 18 months, small to moderate, non-significant benefits (0.26-0.47) of IPSRT vs IPSRT-CR were found on functioning and mood outcomes. CONCLUSIONS: Combining two psychological therapies to target symptomatic and cognitive/functional recovery may reduce the effect of IPSRT, which has implications for treatment planning in clinical practice and for CR trials in mood disorders.

Systematic review of the effects of evidence-based psychotherapies on neurocognitive functioning in mood disorders.

OBJECTIVE: Neurocognitive impairment is considered a core feature of mood disorders. Research has shown that neurocognitive impairment often persists beyond mood symptom resolution and can have significant deleterious effects on interpersonal relationships, academic achievement, occupational functioning and independent living. As such, neurocognitive impairment has become an important target for intervention. In this systematic review, we aimed to examine the extant literature to ascertain whether current standard evidence-based psychotherapies can improve neurocognitive functioning in mood disorders. METHOD: Studies examining changes in neurocognitive functioning following evidence-based psychotherapy were identified using MEDLINE, PsycINFO and Web of Science databases. Given the heterogeneity of study procedures, treatment protocols and patient samples, a narrative rather than meta-analytic review technique was employed. RESULTS: Nineteen studies (21 articles) met inclusion criteria. There was preliminary evidence of improved executive functioning following evidence-based psychotherapy for Major Depressive Disorder and Bipolar Disorder. There was also some signal of reduced negative biases in emotional information processing following psychotherapy in depression. Due to methodological variability across studies however, it was difficult to draw clear conclusions. CONCLUSION: Findings from the current review suggest that evidence-based psychotherapies may influence some aspects of neurocognitive functioning in mood disorders. This continues to be an ongoing area of importance and warrants further research.

Systematic Monitoring of Cognitive Function During Electroconvulsive Therapy: A Retrospective Analysis of Data From a Service Using a Short Cognitive Testing Battery.

OBJECTIVE: International guidelines suggest repeating cognitive testing at intervals throughout a course of electroconvulsive therapy (ECT) to monitor its effects on cognitive function. However, it is apparent that few services do this, and an optimal battery of testing has not yet been established. We aimed to evaluate the utility of such routine cognitive testing in a clinic where patients had been routinely tested at intervals throughout a course of ECT. METHODS: All patients referred for ECT at a public ECT clinic were offered routine cognitive testing to monitor cognitive function during their course of ECT. Testing was conducted at baseline and after 3, 6, and 9 treatments. Analyses examined whether change in individual measures predicted reduction in autobiographical memory at subsequent measures and whether the results that were given to clinicians informed treatment decisions. RESULTS: Changes in cognitive test results were not associated with clinician decisions to change treatment parameters. Only change in digit span forwards after 3 treatments was associated with later reduction in Colombia University Autobiographical Interview - Short Form (CUAMI-SF) of greater than 25%, with a larger improvement in digit span forwards being associated with greater chance of having a 25% reduction in CUAMI-SF. CONCLUSIONS: There was no evidence that the screening undertaken in this clinic had been helpful in determining treatment decisions or that changes in cognitive tests predicted in a reliable way who would later experience changes in autobiographical memory. However, follow-up testing was not completed reliably, and longer-term data regarding autobiographical memory were not collected.

Traumatic imagery following glucocorticoid administration in earthquake-related post-traumatic stress disorder: A preliminary functional magnetic resonance imaging study.

OBJECTIVE: Post-traumatic stress disorder involves excessive retrieval of traumatic memories. Glucocorticoids impair declarative memory retrieval. This preliminary study examined the effect of acute hydrocortisone administration on brain activation in individuals with earthquake-related post-traumatic stress disorder compared with earthquake-exposed healthy individuals, during retrieval of traumatic memories. METHOD: Participants exposed to earthquakes with (n = 11) and without post-traumatic stress disorder (n = 11) underwent two functional magnetic resonance imaging scans, 1-week apart, in a double-blind, placebo-controlled, counter-balanced design. On one occasion, they received oral hydrocortisone (20 mg), and on the other, placebo, 1 hour before scanning. Symptom provocation involved script-driven imagery (traumatic and neutral scripts) and measures of self-reported anxiety. RESULTS: Arterial spin labelling showed that both post-traumatic stress disorder and trauma-exposed controls had significantly reduced cerebral blood flow in response to retrieval of traumatic versus neutral memories in the right hippocampus, parahippocampal gyrus, calcarine sulcus, middle and superior temporal gyrus, posterior cingulate, Heschl's gyrus, inferior parietal lobule, angular gyrus, middle occipital gyrus, supramarginal gyrus, lingual gyrus and cuneus, and the left prefrontal cortex. Hydrocortisone resulted in non-significant trends of increasing subjective distress and reduced regional cerebral blood flow in the left inferior frontal gyrus, left anterior cingulate gyrus, middle temporal gyrus, cerebellum, postcentral gyrus and right frontal pole, during the trauma script. CONCLUSION: Findings do not fit with some aspects of the accepted neurocircuitry model of post-traumatic stress disorder, i.e., failure of the medial prefrontal cortex to quieten hyperresponsive amygdala activity, and the potential therapeutic benefits of hydrocortisone. They do, however, provide further evidence that exposure to earthquake trauma, regardless of whether post-traumatic stress disorder eventuates, impacts brain activity and highlights the importance of inclusion of trauma-exposed comparisons in studies of post-traumatic stress disorder.

A Systematic Review of Cognitive Predictors of Treatment Outcome in Major Depression.

Background: Research suggests that only 50% of patients with major depression respond to psychotherapy or pharmacological treatment, and relapse is common. Therefore, there is interest in elucidating factors that help predict clinical response. Cognitive impairment is a key feature of depression, which often persists beyond remission; thus, the aim of this systematic review was to determine whether baseline cognitive functioning can predict treatment outcomes in individuals with depression. Method: Studies examining cognitive predictors of treatment response in depression were identified using Pub Med and Web of Science databases. Given the heterogeneity of outcome measures, the variety of treatment protocols, and the differing ways in which data was presented and analyzed, a narrative rather than meta-analytic review technique was used. Results: 39 studies met inclusion criteria. Findings in younger adult samples were inconclusive. There was some evidence for a predictive effect of executive function and to a lesser extent, psychomotor speed, on treatment response. There was no evidence of learning or memory being associated with treatment response. In older-aged samples, the evidence was much more consistent, suggesting that poor executive function predicts poor response to SSRIs. Conclusions: Findings from the present review suggest that certain aspects of cognitive functioning, particularly executive function, may be useful in predicting treatment response in depression. This is certainly the case in elderly samples, with evidence suggesting that poor executive functioning predicts poor response to SSRIs. With further research, baseline cognitive functioning may serve as a factor which helps guide clinical decision making. Moreover, cognitive deficits may become targets for specific pharmacological or psychological treatments, with the hope of improving overall outcome.

Brain activation during processing of genuine facial emotion in depression: Preliminary findings.

OBJECTIVE: The current study aimed to examine the neural correlates of processing genuine compared with posed emotional expressions, in depressed and healthy subjects using a novel functional magnetic resonance imaging (fMRI) paradigm METHOD: During fMRI scanning, sixteen depressed patients and ten healthy controls performed an Emotion Categorisation Task, whereby participants were asked to distinguish between genuine and non-genuine (posed or neutral) facial displays of happiness and sadness. RESULTS: Compared to controls, the depressed group showed greater activation whilst processing genuine versus posed facial displays of sadness, in the left medial orbitofrontal cortex, caudate and putamen. The depressed group also showed greater activation whilst processing genuine facial displays of sadness relative to neutral displays, in the bilateral medial frontal/orbitofrontal cortex, left dorsolateral prefrontal cortex, right dorsal anterior cingulate, bilateral posterior cingulate, right superior parietal lobe, left lingual gyrus and cuneus. No differences were found between the two groups for happy facial displays. LIMITATIONS: Relatively small sample sizes and due to the exploratory nature of the study, no correction was made for multiple comparisons. CONCLUSION: The findings of this exploratory study suggest that depressed individuals may show a different pattern of brain activation in response to genuine versus posed facial displays of sadness, compared to healthy individuals. This may have important implications for future studies that wish to examine the neural correlates of facial emotion processing in depression.

Changes in neuropsychological function after treatment with metacognitive therapy or cognitive behavior therapy for depression.

BACKGROUND: Metacognitive therapy (MCT) is an innovative treatment model addressing patterns of negative thinking seen in emotional disorders. Unlike cognitive behavior therapy (CBT), MCT has strategies targeting dysfunctional cognitive and metacognitive processes underlying perseverative thinking patterns and attentional biases. The aim of this pilot study was to compare changes in neuropsychological functioning related to executive function and attention in outpatients with depression following treatment with MCT or CBT. METHODS: Forty-eight participants referred for outpatient treatment of depression were randomized to 12 weeks of MCT (n = 23) or CBT (n = 25). Mood severity and neuropsychological functioning were assessed at pretreatment, 4 weeks, and at end treatment (12 weeks). RESULTS: There were no significant group differences at pretreatment or 4 weeks on any neuropsychological test, although overall both groups showed a small improvement by 4 weeks. At end treatment, the MCT group demonstrated significantly greater improvement in performance on a task requiring spatial working memory and attention than the CBT group. Changes in executive functioning and attention were independent of change in mood symptoms. CONCLUSIONS: MCT may have an advantage over CBT in improving aspects of executive function, including attention. MCT's emphasis on attentional training and flexible control of thinking may have a beneficial effect on neuropsychological functioning, consistent with the purported mechanism of action.

Estrogen treatment enhances nitric oxide bioavailability in normotensive but not hypertensive rats.

BACKGROUND: The effects of estrogen on endothelial function remain controversial. Endothelial function is perturbed in hypertension. We aimed to determine whether pre-existing hypertension can modify endothelial-dependent responses to estrogen. METHODS: We compared the effects of estrogen replacement on endothelial function in healthy female adult Wistar Kyoto (WKY) rats and stroke-prone spontaneously hypertensive rats (SHRSP). Basal and carbachol-stimulated nitric oxide (NO) bioavailability were studied in carotid artery rings in ovariectomized animals treated with estrogen or placebo for 2 weeks in vivo, or after 1 h of incubation in vitro. Basal NO bioavailability was defined as the increase in pressor responses in phenylephrine in the presence of NO synthase blockade. Superoxide (O(2)(-)) levels in aortas were measured by lucigenin chemiluminescence and endothelial NO synthase (eNOS) protein levels by Western blotting. RESULTS: Basal NO bioavailability was increased in WKY treated with estrogen for 2 weeks compared to placebo. In contrast, no change in NO bioavailability was observed in SHRSP. The O(2)(-) levels were higher in SHRSP than in WKY but unaffected by estrogen treatment in either strain. In WKY, but not in SHRSP, estrogen caused upregulation of eNOS. Similarly in vitro exposure to estrogen increased NO bioavailability in WKY but had no effect in SHRSP. In WKY, co-exposure to estrogen and LY294002, a PI3 kinase inhibitor, abrogated the effect of estrogen. CONCLUSIONS: The inability of estrogen to improve endothelial function in SHRSP may relate to a defect in eNOS activation pathways in this hypertensive rat strain.
