Non-Positive Experiences Encountered by Pupils During Participation in a Mindfulness-Informed School-Based Intervention

Mindfulness-informed school-based mental health curricula show much promise in cultivating a positive school climate which supports the well-being and mental health of pupils and staff. However, non-positive pupil outcomes and experiences of school-based mental health interventions are often under-recognised and under-reported. This study sought to capture non-positive pupil experiences of a popular mindfulness-informed curriculum. Some pupils across all schools in the study described non-positive experiences, including having troubling thoughts and emotions, and not finding the programme effective. Contexts surrounding these experiences are explored and linked to existing literature, and subsequent recommendations for improvements are made, including the importance of having clear programme structure, definitions and aims, acknowledging and accommodating fidelity issues as best as possible, and better highlighting the potential for non-positive experiences and how they may be reduced.

Bispecific CD8 Treg modulators regulate a novel regulatory CD8 T cell network and eliminate pathogenic CD4 T cells in live cell co-culture system

INTRODUCTION

Others have described a subset of CD8 T cells (CD8 Treg) with immunosuppressive characteristics in inflammatory disease settings. CD8 Treg activation through canonical T cell receptors results in their oligoclonal expansion and perforin dependent elimination of pathogenic CD4 T cells. We have described the CD8 Treg network in Celiac patients and its potential to eliminate pathogenic CD4 T cells. Here we describe bispecific CD8 Treg modulators that activate CD8 Tregs, resulting in pathogenic CD4 T cell death.

METHODS

Novel bispecific CD8 Treg modulators were tested for target specificity by Octet and cell binding. The functional impact of CD8 Treg modulators was evaluated using flow and Luminex assays, and in a live cell co-culture system using Celiac patient derived CD8 Tregs and gliadin activated CD4 T cell targets. CD8 Treg modulators with specific molecular formats were then ranked for functional efficacy.

RESULTS

We tested a panel of bispecific CD8 Treg modulators with monovalent binding affinities in the low nanomolar range that selectively bind the CD8 Treg subset. Within 48 hours of CD8 Treg modulator addition to T cell co-cultures, CD8 Tregs had a rapid increase of cytolytic markers and degranulation in response to CD4 T cell targets. We observed a concomitant increase of activated CD4 T cell death and decrease of pro-inflammatory cytokines.

CONCLUSIONS

Our results indicate that a targeted approach to engage and activate CD8 Treg reduces pathogenic CD4 T cells. As this newly described CD8 Treg cell network is observed in many autoimmune diseases, we postulate that bispecific CD8 T cell modulators may represent a novel, selective and broadly applicable therapeutic approach for the treatment of human autoimmune diseases.

Demonstration of regulatory CD8 T cell prevalence, phenotype, and functions in autoimmune patients treated with a tolerizing peptide vaccine

INTRODUCTION

Others have described a subset of CD8 T cells with immunosuppressive characteristics in inflammatory disease settings. CD8 Treg activation, through a canonical T cell receptor, results in oligoclonal expansion and perforin dependent elimination of pathogenic CD4 T cells. We have demonstrated the CD8 Treg network in Celiac patients, and that CD8 Tregs can be modulated to enhance their cytolytic elimination of pathogenic CD4 T cells. Here, we evaluate culture conditions to enhance CD8 Treg functions, and describe the impact of a gluten tolerizing peptide vaccine on CD8 Treg in Celiac disease patients.

METHODS

We examined the phenotype and function of Celiac patient-derived peripheral blood CD8 Tregs using flow cytometry, multicolor immunohistochemical staining, supernatant analysis, and TCR sequencing. We then evaluated the impact of a gluten tolerizing peptide vaccine on the CD8 Treg network in Celiac patient derived peripheral blood and tissues.

RESULTS

Using our previously reported phenotypic and functional readouts to define CD8 Treg activity, we describe culture conditions that support oligoclonal CD8 Treg cell expansion, plasticity, and cytolytic function. In patients treated with a gluten tolerizing vaccine, we found evidence for CD8 Treg expansion and preferential recruitment to duodenal tissues; however, pathogenic CD4 T cells were still detectable, suggesting insufficient CD8 Treg functional activation.

CONCLUSION

We describe parameters that support cytolytic CD8 Treg function, as well as the impact of a gluten tolerizing vaccine on the mobilization of CD8 Treg. Collectively, our data support the potential for CD8 Treg directed therapies to eliminate pathogenic CD4 T cells in autoimmune diseases.

Optimal therapeutic targeting by HDAC inhibition in biopsy-derived treatment-naïve diffuse midline glioma models

BACKGROUND

Diffuse midline gliomas (DMGs), including diffuse intrinsic pontine gliomas (DIPGs), have a dismal prognosis, with less than 2% surviving 5 years postdiagnosis. The majority of DIPGs and all DMGs harbor mutations altering the epigenetic regulatory histone tail (H3 K27M). Investigations addressing DMG epigenetics have identified a few promising drugs, including the HDAC inhibitor (HDACi) panobinostat. Here, we use clinically relevant DMG models to identify and validate other effective HDACi and their biomarkers of response.

METHODS

HDAC inhibitors were tested across biopsy-derived treatment-naïve in vitro and in vivo DMG models with biologically relevant radiation resistance. RNA sequencing was performed to define and compare drug efficacy and to map predictive biomarkers of response.

RESULTS

Quisinostat and romidepsin showed efficacy with low nanomolar half-maximal inhibitory concentration (IC50) values (~50 and ~5 nM, respectively). Comparative transcriptome analyses across quisinostat, romidepsin, and panobinostat showed a greater degree of shared biological effects between quisinostat and panobinostat, and less overlap with romidepsin. However, some transcriptional changes were consistent across all 3 drugs at similar biologically effective doses, such as overexpression of troponin T1 slow skeletal type (TNNT1) and downregulation of collagen type 20 alpha 1 chain (COL20A1), identifying these as potential vulnerabilities or on-target biomarkers in DMG. Quisinostat and romidepsin significantly (P < 0.0001) inhibited in vivo tumor growth.

CONCLUSIONS

Our data highlight the utility of treatment-naïve biopsy-derived models; establishes quisinostat and romidepsin as effective in vivo; illuminates potential mechanisms and/or biomarkers of DMG cell lethality due to HDAC inhibition; and emphasizes the need for brain tumor-penetrant versions of potentially efficacious agents.

Thought-Action Fusion in Individuals with a History of Recurrent Depression and Suicidal Depression: Findings from a Community Sample

Although suicidal ideation is one of the most consistent symptoms across recurrent episodes of depression, the mechanisms underpinning its maintenance are poorly understood. In order to develop effective treatments for suicidally depressed patients, understanding what maintains suicidal distress is critical. We hypothesised that Thought–Action Fusion (TAF), i.e., to assume that having a thought has real world consequences, originally described in Obsessive–Compulsive Disorder, might be a bias in recurrently suicidally depressed people. To assess this, we revised the original TAF scale, and assessed TAF in three samples: healthy controls, recurrently depressed individuals with no history of suicidality (D-NS) and individuals with a history of recurrent suicidal depression (D-S). Exploratory and confirmatory factor analyses indicated a three-factor solution of TAF: (1) TAF for uncontrollable events, (2) self-suicidal TAF for suicidal acts related to oneself, and (3) TAF for positive controllable events. Compared to healthy controls, the D-NS group reported significantly higher total TAF, TAF uncontrollable, and TAF self-suicidal subscales, whilst positive controllable TAF was lower compared to healthy controls. Both D-S and D-NS samples reported higher TAF for suicidal thought compared to healthy controls, i.e., believing that having suicidal thoughts means they will act on them, however in the context of low mood this became more pronounced for the D-S group. These findings suggest that targeting TAF both in suicidal and non-suicidal depression has merit.

Therapeutic and Prognostic Implications of BRAF V600E in Pediatric Low-Grade Gliomas

Purpose BRAF V600E is a potentially highly targetable mutation detected in a subset of pediatric low-grade gliomas (PLGGs). Its biologic and clinical effect within this diverse group of tumors remains unknown. Patients and Methods A combined clinical and genetic institutional study of patients with PLGGs with long-term follow-up was performed (N = 510). Clinical and treatment data of patients with BRAF V600E mutated PLGG (n = 99) were compared with a large international independent cohort of patients with BRAF V600E mutated-PLGG (n = 180). Results BRAF V600E mutation was detected in 69 of 405 patients (17%) with PLGG across a broad spectrum of histologies and sites, including midline locations, which are not often routinely biopsied in clinical practice. Patients with BRAF V600E PLGG exhibited poor outcomes after chemotherapy and radiation therapies that resulted in a 10-year progression-free survival of 27% (95% CI, 12.1% to 41.9%) and 60.2% (95% CI, 53.3% to 67.1%) for BRAF V600E and wild-type PLGG, respectively ( P < .001). Additional multivariable clinical and molecular stratification revealed that the extent of resection and CDKN2A deletion contributed independently to poor outcome in BRAF V600E PLGG. A similar independent role for CDKN2A and resection on outcome were observed in the independent cohort. Quantitative imaging analysis revealed progressive disease and a lack of response to conventional chemotherapy in most patients with BRAF V600E PLGG. Conclusion BRAF V600E PLGG constitutes a distinct entity with poor prognosis when treated with current adjuvant therapy.

Severe brachycephalic obstructive airway syndrome is associated with hypercoagulability in dogs

We evaluated whether dogs with severe brachycephalic obstructive airway syndrome (BOAS) developed a hypercoagulable state similar to people with obstructive sleep apnea. Five dogs with grade 3 BOAS were included as well as 5 healthy control Labrador Retrievers. Venous blood samples were collected from each dog for performance of thromboelastography and determination of hematocrit and platelet count. Groups were compared using a t-test, with p < 0.05 considered significant. Thromboelastography results identified that all BOAS dogs were hypercoagulable compared to the Labradors, having significantly shortened clotting time with increased angle, maximal amplitude, and clot rigidity. BOAS dogs also had evidence of delayed fibrinolysis. These results are consistent with, but more severe than, those previously documented in apparently healthy Bulldogs. Together, these findings support the presence of a hypercoagulable state in brachycephalic dogs, and suggest that this state is amplified by increasing severity of BOAS.

Surgical treatment of post-traumatic distraction posterior urethral strictures

Approximately 4-14% pelvic fractures cause a posterior urethral injury. Pelvic fractures associated with straddle injuries or large trauma accidents are more frequently involved with this kind of lesions. Primary open repair of the urethral injury is discouraged in the acute setting. 3-6 months after urinary diversion a formal open reconstruction can be safely attempted. This gives time for scar maturation, reabsorption of pelvic hematomas, and relative restoration of anatomical fascial layers. The complexity of such interventions can be minimized following proper diagnostic and surgical protocols. Anastomotic urethroplasty under the precepts of the progressive perineal approach provides an excellent treatment option for these patients. The aim of this paper is the detailed description of the procedure for the treatment of such injuries.

Self-discrepancy in students with bipolar disorder II or NOS

BACKGROUND

Studies on self-representation in bipolar disorder have mainly focused on the single dimension of self-esteem and recruited patients either in episode or in remission. The aim of the study was to examine multi-dimensional aspects of the self (discrepancy between actual- and ideal-selves and between actual- and feared-selves) in a student sample with a history of significant experience of hypomania (with or without experience of major depression) as compared to healthy control students.

METHODS

Bipolar students and healthy control students completed the Self-Discrepancy Questionnaire (SDQ: Carver, Lawrence, & Scheier, 1999). The degree of similarity to, and the perceived likelihood of ideal-self and feared-self characteristics were assessed.

RESULTS

The difference between the groups in level of ideal-self similarity was at trend level. Students with prior hypomania but no history of depression showed higher similarity to their feared-self than healthy controls and also rated themselves as more likely to have these feared-self characteristics in the future.

LIMITATION

The small sample size, especially in the bipolar group with no history of depression, limits the power of the study.

CONCLUSIONS

The presence of ideal-self discrepancy was not convincingly demonstrated in this sample and it is possible that where it has been identified in previous studies it may, at least in part, represent a scar of previous episodes of depression or mania rather than a predisposing factor. However a sub-sample of students who had experienced hypomania in the absence of history of depression were distinguished from healthy controls in perceived closeness to the feared-self qualities. The feared-self concept warrants further investigation in bipolar patients.

Dysfunctional beliefs in bipolar disorder: hypomanic vs. depressive attitudes

BACKGROUND

To date the effect of cognitive behavioural therapy modified for bipolar disorder has been inconsistent and sometimes disappointing. However studies exploring cognitive style in bipolar disorder have not identified the unique patterns of beliefs specific to bipolar disorder. The current study examines whether Mansell's hypomania-related dysfunctional belief scale specifically identifies bipolar disorder patients.

METHOD

Forty remitted bipolar patients, twenty remitted unipolar patients and twenty healthy controls completed the Hypomanic Attitudes and Positive Prediction Inventory (HAPPI) and the Dysfunctional Attitude Scale (DAS).

RESULTS

The remitted bipolar group scored higher than the unipolar and healthy control groups on the HAPPI scale overall score and on three subscales that measured self-catastrophic beliefs, beliefs related to negative responses from other people when in elevated mood and beliefs related the response style to activation and elevation.

CONCLUSION

The study finds evidence of unique dysfunctional beliefs elevated only in remitted bipolar patients. Such findings could be used to inform the development of a specific cognitive behavioural therapy for bipolar disorder.

Cognitive behaviour therapy for improving social recovery in psychosis: a report from the ISREP MRC Trial Platform Study (Improving Social Recovery in Early Psychosis)

BACKGROUND

This study reports on a preliminary evaluation of a cognitive behavioural intervention to improve social recovery among young people in the early stages of psychosis showing persistent signs of poor social functioning and unemployment. The study was a single-blind randomized controlled trial (RCT) with two arms, 35 participants receiving cognitive behaviour therapy (CBT) plus treatment as usual (TAU), and 42 participants receiving TAU alone. Participants were assessed at baseline and post-treatment.

METHOD

Seventy-seven participants were recruited from secondary mental health teams after presenting with a history of unemployment and poor social outcome. The cognitive behavioural intervention was delivered over a 9-month period with a mean of 12 sessions. The primary outcomes were weekly hours spent in constructive economic and structured activity. A range of secondary and tertiary outcomes were also assessed.

RESULTS

Intention-to-treat analysis on the combined affective and non-affective psychosis sample showed no significant impact of treatment on primary or secondary outcomes. However, analysis of interactions by diagnostic subgroup was significant for secondary symptomatic outcomes on the Positive and Negative Syndrome Scale (PANSS) [F(1, 69)=3.99, p=0.05]. Subsequent exploratory analyses within diagnostic subgroups revealed clinically important and significant improvements in weekly hours in constructive and structured activity and PANSS scores among people with non-affective psychosis.

CONCLUSIONS

The primary study comparison provided no clear evidence for the benefit of CBT in a combined sample of patients. However, planned analyses with diagnostic subgroups showed important benefits for CBT among people with non-affective psychosis who have social recovery problems. These promising results need to be independently replicated in a larger, multi-centre RCT.

Patient preferences for chemoradiation-related side effects

e20604

Background: Patients (pts) undergoing chemoradiation (CRT) face intense treatment (tx) schedules and adverse tx- related side-effects (SEs). We conducted this study to determine whether pts’ preferences (PREFs) for CRT-related SEs changed over tx duration. Methods: We used the visual analog scale (VAS) and modified time trade-off (TTO) to assess PREFs of newly diagnosed pts with gynecologic (GYN) and gastrointestinal (GI) cancers scheduled to receive CRT. Pts evaluated 16 SE health state scenarios during interviews conducted at 3 points in time: T1=prior to starting CRT; T2=2–3 weeks after starting CRT; and T3=4–6 weeks after completing CRT. Using the VAS, pts ranked SEs on a scale of 0=worst to 100=best. The TTO asked pts whether they would accept a hypothetical tx for a specified time with the SE in question or a tx for a shorter length of time that involved a worse SE profile. PREF scores were converted to 0.0=least preferred to 1.0=most preferred. Mann-Whitney and Kruskal-Wallis tests were used to analyze data. P- values were adjusted for multiple comparisons. Results: PREFs were collected from 93 pts (GYN=43; GI=50). 46/93 pts were female (3 women were GI pts). Median age was 53.7 yrs. Pts received a median of 5 chemo cycles (31/50 GI and all GYN pts received platinum) and 5.4 wks of external beam radiation. Median time between T1-T2 was 2.6 wks and T2-T3 was 9.1 wks. TTO PREFs were stable over time regardless of disease group or tx regimen. VAS scores for 7 SEs worsened significantly after initiation of CRT and remained low despite completion of CRT ( table ). Pts gave low baseline PREF scores for diarrhea, fatigue, and loss of appetite; these did not change significantly over time. Conclusions: Pts receiving CRT were willing to accept tx of longer duration with less severe SEs instead of shorter tx with more severe SEs. Relative to other SEs, pts rated GI-associated SEs lower after initiation of CRT. Ratings remained low 4–6 weeks after tx completion. Further studies are needed to determine whether pts’ experiences with and perceptions of SEs influence tx compliance.

Minimizing the complications associated with migrating catheters

This article seeks to explore the clinical practice of urinary catheter fixation. Traditionally, this area of practice has been neglected and nurses are familiar with tension lesions and dermal problems associated with inappropriate or incorrect urinary catheter fixation. A novel solution to this problem is a catheter fixation device. This device secures the catheter safely, making clinical practice safer and the experience of catheterization more tolerable for the patient. An example of a urinary catheter fixation device available in the UK is Bard's StatLock.

Mindfulness-based Cognitive Therapy (MBCT) in bipolar disorder: preliminary evaluation of immediate effects on between-episode functioning

BACKGROUND

Bipolar disorder is highly recurrent and rates of comorbidity are high. Studies have pointed to anxiety comorbidity as one factor associated with risk of suicide attempts and poor overall outcome. This study aimed to explore the feasibility and potential benefits of a new psychological treatment (Mindfulness-based Cognitive Therapy: MBCT) for people with bipolar disorder focusing on between-episode anxiety and depressive symptoms.

METHODS

The study used data from a pilot randomized trial of MBCT for people with bipolar disorder in remission, focusing on between-episode anxiety and depressive symptoms. Immediate effects of MBCT versus waitlist on levels of anxiety and depression were compared between unipolar and bipolar participants.

RESULTS

The results suggest that MBCT led to improved immediate outcomes in terms of anxiety which were specific to the bipolar group. Both bipolar and unipolar participants allocated to MBCT showed reductions in residual depressive symptoms relative to those allocated to the waitlist condition.

LIMITATIONS

Analyses were based on a small sample, limiting power. Additionally the study recruited participants with suicidal ideation or behaviour so the findings cannot immediately be generalized to individuals without these symptoms.

CONCLUSIONS

The study, although preliminary, suggests an immediate effect of MBCT on anxiety and depressive symptoms among bipolar participants with suicidal ideation or behaviour, and indicates that further research into the use of MBCT with bipolar patients may be warranted.

Prevalence and temporal patterns of persistence of symptoms in 165 rectal cancer patients receiving preoperative chemoradiation therapy

19580

Background: The symptom burden during preoperative chemoradiation therapy for rectal cancer (CRT) has not been objectively characterized previously. The severity and temporal patterns of patient self-reported symptoms during CRT were assessed using the MD Anderson Symptom Inventory (MDASI). Methods: 165 consecutive patients with T3/T4/N+ rectal cancer received 45–55 Gy in 25–30 fractions concurrently with capecitabine chemotherapy. No additional intervention beyond standard supportive care was triggered by the MDASI score severity. The mean symptom scores were grouped into three time points; weeks 0–1 (“baseline”), 2–3 (“early treatment”), and 4–6 (“late treatment”) of CRT. Lowess curves were used to demonstrate the severity and pattern of individual symptoms. Linear mixed models were used to assess changes in symptom severity. Repeated measures analyses compared the mean severity of the reported symptoms at the three time points. Results: The median number of data points per patient was 3.0 (range, 1–6), for a total of 533 data points. Lowess curves demonstrated increasing symptom severity during CRT, which was confirmed by the linear mixed models analysis for each symptom (p<0.05). Using repeated measures with the three time points, these symptoms, except fatigue, showed statistically significant differences in mean severity ( Table 1 ). High baseline fatigue levels blunted statistical power to detect differences during CRT. Despite normal hemoglobin levels, fatigue remained the most severe symptom. Placed in context, the mean symptom levels remained mild throughout CRT. Conclusions: CRT was associated with a high prevalence of and progressive increase in symptom burden during therapy although the functional impact was limited. All symptoms followed clinically recognized patterns. The linear mixed model, a more sensitive measure of these trends, is recommended for prospective studies of interventions for symptom control
