Perinatal Women's Perspectives of, and Engagement in, Digital Emotional Well-Being Training: Mixed Methods Study.

BACKGROUND: Psychological distress in the early postpartum period can have long-lasting deleterious effects on a mother's well-being and negatively affect her infant's development. Intervention approaches based in contemplative practices such as mindfulness and loving-kindness and compassion are intended to alleviate distress and cultivate well-being and can be delivered effectively as digital mental health interventions (DMHIs). OBJECTIVE: To understand the feasibility of engaging perinatal women in digital interventions, this study aimed to document participants' experiences in the Mums Minds Matter (MMM) study, a pilot randomized controlled trial comparing mindfulness, loving-kindness and compassion, and progressive muscle relaxation training delivered in a digital format and undertaken during pregnancy. To assess the different stages of engagement during and after the intervention, we adapted the connect, attend, participate, enact (CAPE) framework that is based on the idea that individuals go through different stages of engagement before they are able to enact change. METHODS: The MMM study was nested within a longitudinal birth cohort, The ORIGINS Project. We aimed to recruit 25 participants per randomization arm. Data were collected sequentially during the intervention through regular web-based surveys over 8 weeks, with opportunities to provide regular feedback. In the postintervention phase, qualitative data were collected through purposive sampling. RESULTS: Of 310 eligible women, 84 (27.1% [connect rate]) enrolled to participate in MMM. Of the remaining 226 women who did not proceed to randomization, 223 (98.7%) failed to complete the baseline surveys and timed out of eligibility (after 30 weeks' gestation), and 3 (1.3%) displayed high psychological distress scores. Across all program groups, 17 (20% [attend rate]) of the 84 participants actively opted out, although more may have disengaged from the intervention but did not withdraw. The main reasons for withdrawal were busy life and other priorities. In this study, we assessed active engagement and ongoing skills use (participate and enact) through postintervention interviews. We undertook 15 participant interviews, conducted 1 month to 3 months after the intervention. Our results provide insights into participant barriers and enablers as well as app changes, such as the ability to choose topics, daily reminders, case studies, and diversity in sounds. Implementing a DMHI that is brief, includes frequent prompts or nudges, and is easily accessible is a key strategy to target perinatal women. CONCLUSIONS: Our research will enable future app designs that are sufficiently nuanced to maximize the uptake, engagement, and application of mental health skills and contemplative practices in the perinatal period. Providing convenient access to engaging and effective prevention programs is critical and should be part of prenatal self-care. Our research underscores the appeal and feasibility of digital intervention approaches based in contemplative practices for perinatal women.

Understanding Engagement in Digital Mental Health and Well-being Programs for Women in the Perinatal Period: Systematic Review Without Meta-analysis.

BACKGROUND: Pregnancy and the postnatal period can be a time of increased psychological distress, which can be detrimental to both the mother and the developing child. Digital interventions are cost-effective and accessible tools to support positive mental health in women during the perinatal period. Although studies report efficacy, a key concern regarding web-based interventions is the lack of engagement leading to drop out, lack of participation, or reduced potential intervention benefits. OBJECTIVE: This systematic review aimed to understand the reporting and levels of engagement in studies of digital psychological mental health or well-being interventions administered during the perinatal period. Specific objectives were to understand how studies report engagement across 4 domains specified in the Connect, Attend, Participate, and Enact (CAPE) model, make recommendations on best practices to report engagement in digital mental health interventions (DMHIs), and understand levels of engagement in intervention studies in this area. To maximize the utility of this systematic review, we intended to develop practical tools for public health use: to develop a logic model to reference the theory of change, evaluate the studies using the CAPE framework, and develop a guide for future data collection to enable consistent reporting in digital interventions. METHODS: This systematic review used the Cochrane Synthesis Without Meta-analysis reporting guidelines. This study aimed to identify studies reporting DMHIs delivered during the perinatal period in women with subclinical mood symptoms. A systematic database search was used to identify relevant papers using the Ovid Platform for MEDLINE, PsycINFO, EMBASE, Scopus, Web of Science, and Medical Subject Headings on Demand for all English-language articles published in the past 10 years. RESULTS: Searches generated a database of 3473 potentially eligible studies, with a final selection of 16 (0.46%) studies grouped by study design. Participant engagement was evaluated using the CAPE framework and comparable variables were described. All studies reported at least one engagement metric. However, the measures used were inconsistent, which may have contributed to the wide-ranging results. There was insufficient reporting for enactment (ie, participants' real-world use of intervention skills), with only 38% (6/16) of studies clearly recording longer-term practice through postintervention interviews. The logic model proposes ways of conceptualizing and reporting engagement details in DMHIs more consistently in the future. CONCLUSIONS: The perinatal period is the optimal time to intervene with strength-based digital tools to build positive mental health. Despite the growing number of studies on digital interventions, few robustly explore engagement, and there is limited evidence of long-term skill use beyond the intervention period. Our results indicate variability in the reporting of both short- and long-term participant engagement behaviors, and we recommend the adoption of standardized reporting metrics in future digital interventions.

Systematic Review and Meta-Analysis: Early Irritability as a Transdiagnostic Neurodevelopmental Vulnerability to Later Mental Health Problems.

OBJECTIVE: Irritability is a transdiagnostic indicator of child and adolescent internalizing and externalizing problems that is measurable from early life. The objective of this systematic review was to determine the strength of the association between irritability measured from 0 to 5 years and later internalizing and externalizing problems, to identify mediators and moderators of these relationships, and to explore whether the strength of the association varied according to irritability operationalization. METHOD: Relevant studies published in peer-reviewed, English-language journals between the years 2000 and 2021 were sought from EMBASE, PsycINFO, MEDLINE, CINAHL, and ERIC. We synthesized studies that included a measure of irritability within the first 5 years of life and reported associations with later internalizing and/or externalizing problems. Methodological quality was assessed using the JBI-SUMARI Critical Appraisal Checklist. RESULTS: Of 29,818 identified studies, 98 met inclusion criteria, with a total number of 932,229 participants. Meta-analysis was conducted on 70 studies (n = 831,913). Small, pooled associations were observed between infant irritability (0-12 months) and later internalizing (r = 0.14, 95% CI = 0.09, 0.20) and externalizing symptoms (r = 0.16, 95% CI = 0.11, 0.21) symptoms. For toddler/preschool irritability (13-60 months), small-to-moderate pooled associations were observed for internalizing (r = 0.21, 95% CI = 0.14, 0.28) and externalizing (r = 0.24, 95% CI = 0.18, 0.29) symptoms. These associations were not moderated by the lag between irritability and outcome assessment, although the strength of the associations varied according to irritability operationalization. CONCLUSION: Early irritability is a consistent transdiagnostic predictor of internalizing and externalizing symptoms in childhood and adolescence. More work is required to understand how to accurately characterize irritability across this developmental period, and to understand mechanisms underlying the relationship between early irritability and later mental health problems.

Characteristics and clinical outcomes in young-onset cholangiocarcinoma.

BACKGROUND: While the incidence of cholangiocarcinoma is rising, little is known about young-onset disease. We compared clinical characteristics and outcomes between patients with young-onset cholangiocarcinoma, diagnosed between the ages of 18 and <50 years, and patients with typical-onset cholangiocarcinoma, diagnosed at age 50 years or greater. METHODS: We used the National Cancer Database to identify patients with young-onset cholangiocarcinoma (n = 2520) and typical-onset cholangiocarcinoma (n = 23,826). We compared the frequency of demographic and clinical characteristics between the two groups. We compared overall survival between the two groups using multivariable Cox regression analysis after adjusting for age, gender, race/ethnicity, comorbidity, facility type, tumor location, tumor stage, surgical status, and receipt of radiotherapy, chemotherapy and surgery. RESULTS: When compared to patients with typical-onset disease (median age 68 years), patients with young-onset cholangiocarcinoma (median age 44 years) were more likely to be non-White (35.0% vs. 27.4%, p < 0.01), and had lower overall comorbidity burden. Patients with young-onset disease had a greater proportion of intrahepatic cholangiocarcinoma (56.0% vs. 45.5%, p < 0.001) and stage IV disease (50.5% vs. 43.5%, p < 0.001). Younger patients were more likely than typical-onset patients to receive definitive surgery (30.9% vs. 25.0%, p < 0.001), radiation (27.7% vs. 19.6%, p < 0.001) and chemotherapy (73.1% vs. 50.1%, p < 0.001). In adjusted analyses, patients with young-onset disease had a 15% decreased risk of death, compared with patients with typical-onset disease (HR 0.85 [95% CI 0.80-0.89], p < 0.001). CONCLUSIONS: Patients with young-onset cholangiocarcinoma may represent a demographically and clinically distinct group from those with more typical-onset disease.

Time-out for well-being: A mixed methods evaluation of attitudes and likelihood to engage in different types of online emotional well-being programmes in the perinatal period.

BACKGROUND: Positive maternal mental health during the perinatal period contributes to general well-being and positive emotional bonds with the child, encouraging an optimal developmental trajectory. Online interventions to enhance maternal well-being and develop coping skills, such as meditation-based interventions, can be a low-cost way to improve mother and child outcomes. However, this depends on end-user engagement. To date, there is limited evidence about women's willingness to engage and preferences for online programmes. OBJECTIVES: This study explored pregnant women's attitudes towards and likelihood to undertake minimal online well-being training programmes (mindfulness, self-compassion, or general relaxation), engagement barriers and enablers, and programme structure preferences. DESIGN: A mixed methods triangulation design was undertaken using a validating quantitative model. Quantile regressions were applied to the quantitative data. Content analysis was undertaken for the qualitative data. METHODS: Consenting pregnant women (n = 151) were randomized equally to read about three online programme types. Participants were sent an information leaflet, tested by a consumer panel prior to distribution. RESULTS: Participants generally held positive attitudes about all three types of interventions, with no statistically significant differences in preferences between programme types. Participants appreciated the importance of mental health and were receptive to fostering skills to support their emotional well-being and stress management. The most frequent perceived barriers were lack of time, tiredness, and forgetfulness. Programme structure preferences indicated one to two modules per week, less than 15 min in duration, and over 4 weeks. Programme functionality, such as regular reminders and easy accessibility, is important to end users. CONCLUSION: Our findings reinforce the importance of determining participant preferences in designing and communicating engaging interventions for perinatal women. This research contributes to the understanding of population-based interventions that can be provided as simple, scalable, cost-effective, and home-based activities in pregnancy for the benefit of individuals, their families, and society more broadly.

Australian Psychologists Experiences with Digital Mental Health: a Qualitative Investigation.

Digital mental health is changing the landscape of service delivery by addressing challenges associated with traditional therapy. However, practitioners' use of these resources remains underexamined. This study explored psychologists' attitudes and experiences with digital mental health intervention. Taking a qualitative exploratory approach via thematic analysis, the study sought to answer the following research questions: (i) How do psychologists perceive digital mental health? and (ii) What is their experience using digital mental health as part of routine practice? Ten practising psychologists participated in online semi-structured interviews (approximately 50 min), with interviews then transcribed verbatim. Interview data were analysed according to the six-phase approach to thematic analysis proposed by Braun and Clarke. Three themes were identified: (1) attitudes towards digital mental health; (2) use within routine practice; and (3) perspectives on an effective model for implementation. Practitioners play a major role in the design and delivery of digital mental health services. Barriers and facilitators at the practitioner-level (e.g. knowledge and competence with tools, perceptions on the utility of digital interventions) and the service-level (e.g. government support for digital health) should be considered in the future design of digital mental health resources and service delivery.

Racial and Ethnic Differences in Genomic Profiling of Early Onset Colorectal Cancer.

The incidence and mortality of early onset colorectal cancer (EOCRC) is rising; outcomes appear to differ by race and ethnicity. We aimed to assess differences in mutational landscape and gene expression of EOCRC by racial and ethnic groups (non-Hispanic Asian, non-Hispanic Black, non-Hispanic White, White Hispanic) using data from the American Association for Cancer Research Project GENIE (10.2) and University of Texas Southwestern, the latter enriched in Hispanic patients. All statistical tests were 2-sided. Of 1752 EOCRC patients, non-Hispanic Black patients had higher rates of KRAS mutations (60.9%; P = .001, q = 0.015), and non-Hispanic White and non-Hispanic Black patients had higher rates of APC mutations (77.1% and 76.6% among non-Hispanic White and non-Hispanic Black patients, respectively; P = .001, q = 0.015) via the Fisher exact test with Benjamini-Hochberg correction. Using R packages DESeq2 and clusterProfiler, we found that White Hispanic patients had increased expression of genes involved in oxidative phosphorylation (P < .001, q = 0.025). Genomic profiling has the potential to identify novel diagnostics and influence individualized treatment options to address the currently limited prognosis of EOCRC.

Trends in Adjuvant Chemotherapy Use Among Stage III Colon Cancer in Non-Elderly and Low Comorbidity Patients.

BACKGROUND: Adjuvant chemotherapy for stage III colon cancer is underutilized in the United States. The aim of this study was to assess the use of adjuvant chemotherapy in younger and medically fit patients and analyze the socioeconomic factors associated with its utilization. METHODS: Using the National Cancer Database from 2004 to 2015, we selected stage III colon cancer patients between age 18 to 65, Charlson-Deyo Comorbidity Index (CDCI) of 0 or 1, and those that survived at least 12 months after surgery. We then compared patients that underwent surgery only with those that received adjuvant chemotherapy. Multivariable logistic regression analysis was performed to identify variables associated with adjuvant chemotherapy use in the population. Overall survival was estimated by Kaplan-Meier curves. RESULTS: Of the 48,336 patients that met inclusion criteria, 43,315 (90%) received adjuvant chemotherapy. The utilization of adjuvant chemotherapy increased from 87% in 2004 to 91% in 2015. On multivariable regression analysis, the use of adjuvant chemotherapy was lower among males, Non-Hispanic Blacks and Hispanics, low-grade cancer, left-sided tumors, CDCI 1, those who travel ≥ 50 miles, yearly income < $40,227, and uninsured patients. The most common reason for the omission of adjuvant chemotherapy was the patient or caregiver's choice (40% between 2013 and 2015). The 5-year and 10-year overall survival rates were 76.7% and 63.8% respectively, in those who received adjuvant chemotherapy as compared to 65.1% and 49.3% in those who underwent surgery only (P < .001). CONCLUSION: In young and medically fit stage III colon cancer patients, most patients received guideline-compliant care in the United States. However, socioeconomic disparities adversely impacted the use of adjuvant chemotherapy. The patient or caregiver's decision was the most common reason for non-adherence to adjuvant chemotherapy and lead to poor survival outcomes. Emphasis should be placed on developing patient-centered strategies to improve adherence to chemotherapy in all patients.

Don't Get Lost in Translation: Integrating Developmental and Implementation Sciences to Accelerate Real-World Impact on Children's Development, Health, and Wellbeing.

Translation of developmental science discoveries is impeded by numerous barriers at different stages of the research-to-practice pipeline. Actualization of the vast potential of the developmental sciences to improve children's health and development in the real world is imperative but has not yet been fully realized. In this commentary, we argue that an integrated developmental-implementation sciences framework will result in a translational mindset essential for accelerating real world impact. We delineate key principles and methods of implementation science of salience to the developmental science audience, lay out a potential synthesis between implementation and developmental sciences, provide an illustration of the Mental Health, Earlier Partnership (MHE-P), and set actionable steps for realization. Blending these approaches along with wide-spread adoption of the translational mindset has transformative potential for population-level impact of developmental science discovery.

Self-reported reasons for colonoscopy among adults aged 45-49 versus 50 years and older from 2010-2018.

BACKGROUND: In May of 2018, the American Cancer Society lowered the age of colorectal cancer (CRC) screening initiation from 50 to 45 years and in October 2020, United States Preventive Services Task Force published draft guidelines also lowering age of screening initiation to 45 years. Evaluating guideline adherence is needed; however, the majority of prior research on cancer screening do not distinguish whether colonoscopy was performed for true screening purposes or for post-symptomatic diagnosis. METHODS: Using data from the National Health Interview Survey between 2010 to mid-2018, we assessed response to the question "What was the MAIN reason you had [last] colonoscopy?" stratified by age (45-49 versus 50+ years). Multivariable logistic regression defined adjusted odds ratios of receiving last colonoscopy for screening controlling for relevant demographic characteristics. To estimate the cost burden of colonoscopy, the proportion of respondents reporting paying out of pocket for their last colonoscopy was assessed. RESULTS: Among 29,074 participants who had undergone a colonoscopy, 44.4 % of those aged 45-50 reported routine procedure as the reason for their most recent colonoscopy, as compared to 82.4 % in the 50+ age group (p < 0.001). Characteristics associated with undergoing colonoscopy as a routine procedure included Black race and male sex for both age cohorts (p < 0.01 for all). Notably, almost half (46.9 %) of participants younger than 50 years paid part of or the full cost of their colonoscopy, as compared to 30.7 % over the age of 50 (p < 0.001). CONCLUSIONS: The majority of adults aged 45-49 self-report that last colonoscopy was not performed for screening, which is unsurprising given guidelines for screening for individuals under 50. As guidelines change, continued surveillance of colonoscopy patterns across age cohorts is needed, and studies should also incorporate reasons for testing.

Can Positive Mindsets Be Protective Against Stress and Isolation Experienced during the COVID-19 Pandemic? A Mixed Methods Approach to Understanding Emotional Health and Wellbeing Needs of Perinatal Women.

The aim of this study was to explore the relationship between emotional health and wellbeing and support needs of perinatal women during the COVID-19 pandemic, and to understand their experiences and need for support. This is a potentially vulnerable group and a critical developmental phase for women and infants. A mixed methods design was used to collect quantitative and qualitative data that provided a robust insight into their unique needs. A total of 174 women who were either pregnant or post-birth participated. The main findings demonstrated that women in this cohort experienced varying levels of stress and isolation but also positive experiences. Exploring the relationship between mental health (perceived stress and wellbeing) and resilience (mindfulness and self-compassion) revealed an association between positive mental health and higher levels of mindfulness and self-compassion. Positive mindsets may be protective against psychological distress for the mother and her child, suggesting that meditation-based or similar training might help support expectant and post-birth mothers during times of crisis, such as a pandemic. This information could be used to make recommendations for future planning for practitioners and policymakers in preparing for prospective infection waves, pandemics, or natural disasters, and could be used to develop targeted tools, support, and care.

Racial/Ethnic Disparities and Survival Characteristics in Non-Pancreatic Gastrointestinal Tract Neuroendocrine Tumors.

Background: We studied the effect of race and ethnicity on disease characteristics and survival in gastrointestinal neuroendocrine tumors. Methods: The Surveillance, Epidemiology, and End Results database was used to select patients with non-pancreatic gastrointestinal neuroendocrine tumors diagnosed between 2004 and 2015. Trends in survival were evaluated among three groups: Hispanic, non-Hispanic White, and non-Hispanic Black. Kaplan-Meier and Cox regression methods were performed to calculate overall survival and cause-specific survival after adjusting for patient and tumor characteristics. Results: A total of 26,399 patients were included in the study: 65.1% were non-Hispanic White, 19.9% were non-Hispanic Black, and 15% were Hispanic. Non-Hispanic White patients were more likely to be male (50.0%, p < 0.001), older than 60 years (48.0%, p < 0.001), and present with metastatic disease (17.7%, p < 0.001). Non-Hispanic White patients had small intestine neuroendocrine tumors, while Hispanic and non-Hispanic Black patients had rectum neuroendocrine tumors as the most common primary site. Hispanic patients had better overall survival, while non-Hispanic Black patients had better cause-specific survival versus non-Hispanic White patients. This finding was confirmed on multivariable analysis where Hispanic patients had improved overall survival compared to non-Hispanic White patients (Hazard ratio (HR): 0.89 (0.81-0.97)), whereas non-Hispanic Black patients had better cause-specific survival compared to non-Hispanic White patients (HR: 0.89 (0.80-0.98)). Conclusions: Race/ethnicity is an independent prognostic factor in patients with gastrointestinal neuroendocrine tumors.

Chronic traumatic encephalopathy in an epilepsy surgery cohort: Clinical and pathologic findings.

OBJECTIVE: To determine the occurrence of chronic traumatic encephalopathy (CTE) in young adult patients undergoing epilepsy surgery. METHODS: Ten patients who underwent epilepsy surgery were randomly selected for this retrospective study. The patients were 18-45 years of age, had preoperative neuropsychological evaluation, and had 1 year postoperative follow-up. Microscopic sections from resections were evaluated for the presence of CTE with standard stains and antibodies to tau (clone AT8). RESULTS: The median age at resection was 32.5 years (range 23-43) and the median duration of seizures was 23.5 years (range 3-28). Eight had a history of head injury. Preoperative neuropsychological testing showed mild to moderate cognitive impairment in 8 patients (80%). Pathologic examination in one patient showed focal sparse tau-immunoreactive lesions along descending rami and cortical gyral depths of the resected frontal lobe. Nine patients had no evidence of CTE. All focal cortical resections showed variable subpial and subcortical gliosis commonly identified in patients with chronic seizure disorders. CONCLUSIONS: The present small retrospective observational study suggests that CTE may occur, but appears uncommon, in young adult patients undergoing surgical treatment for drug-resistant focal epilepsy. The significance of these findings requires further investigation to define the relative importance of tau accumulation in younger adult patients with drug-resistant focal epilepsy and cognitive decline.

Frequent sleep-related bitemporal focal seizures in transient epileptic amnesia syndrome: Evidence from ictal video-EEG.

Two patients who shared similar presenting clinical features of anterograde and retrograde autobiographical amnesia typical of transient epileptic amnesia (TEA) underwent prolonged video electroencephalogram (VEEG) monitoring and were found to have sleep-activated epileptiform activity and frequent subclinical bitemporal seizures predominantly during sleep. Case 1 is a 59-year-old woman whose presenting complaint was memory impairment. Over 18 months, she had three distinct 8-h-long episodes of confusion and disorientation with persistent anterograde and retrograde autobiographical amnesia. VEEG recorded frequent interictal bitemporal sharp waves confined to sleep, and 14 subclinical seizures, also mostly during sleep. Case 2 is a 50-year-old woman with known focal epilepsy also presented with memory complaints. Over the course of 1 year, she had two discrete 2-h-long episodes of amnesia, with ongoing anterograde and retrograde autobiographical amnesia. VEEG recorded independent bitemporal sharp waves, and 14 subclinical seizures during sleep and drowsiness. Memory impairment improved in both patients with successful treatment of their seizures. Although the etiology of accelerated long-term forgetting (ALF) and remote memory impairment (RMI) in transient epileptic amnesia (TEA) is unknown, these cases suggest frequent sleep-related seizures may contribute, and they highlight the importance of video-EEG monitoring.

Evidence on Use of Neuroimaging for Surgical Treatment of Temporal Lobe Epilepsy: A Systematic Review.

IMPORTANCE: Surgery is an effective treatment for drug-resistant focal epilepsy. Neuroimaging studies are considered essential in the diagnostic evaluation of individuals with medically refractory focal seizures being considered for surgical treatment. OBJECTIVES: To review the evidence for the use of neuroimaging studies in the selection of patients with drug-resistant temporal lobe epilepsy for focal cortical resection and discuss the prognostic importance of selected techniques. EVIDENCE REVIEW: Randomized clinical trials, meta-analyses, and clinical retrospective case studies (≥20 patients with ≥1 year of follow-up) were identified using Medical Subject Headings and indexed text terms in EMBASE (1988-November 29, 2014); MEDLINE (1946-December 2, 2014), Cochrane Central Register of Controlled Trials (1991-October 31, 2014), and Cochrane Database of Systematic Reviews (2005-October 31, 2014). Twenty-seven articles describing 3163 patients were included. Neuroimaging techniques analyzed included magnetic resonance imaging (MRI), positron emission tomography (PET), and single-photon emission computed tomography (SPECT). Subpopulations and prognostic factors were identified. FINDINGS: Of the 27 studies evaluated (3163 patients), 7 showed the outcome was more favorable in patients with MRI-identified hippocampal atrophy indicating mesial temporal sclerosis. Five additional studies indicated that the outcome was less favorable in patients with unremarkable MRI studies. There are conflicting findings regarding the prognostic importance of PET-identified focal hypometabolism; however, 2 investigations indicated that the presence of a PET imaging study demonstrating abnormalities in individuals with unremarkable MRI results showed an operative outcome similar to that in patients with mesial temporal sclerosis. The studies assessing SPECT use in temporal lobe epilepsy did not reveal a correlation with outcome. CONCLUSIONS AND RELEVANCE: There is strong evidence that preoperative MRI-identified hippocampal atrophy consistent with mesial temporal sclerosis concordant with the seizure origin in the temporal lobe is a significant factor associated with a favorable outcome. PET studies may be valuable in individuals with unremarkable MRI findings. The current evidence does not support the prognostic importance of SPECT in patients undergoing temporal lobe surgery.

Self-Compassion, Emotion Regulation and Stress among Australian Psychologists: Testing an Emotion Regulation Model of Self-Compassion Using Structural Equation Modeling.

Psychologists tend to report high levels of occupational stress, with serious implications for themselves, their clients, and the discipline as a whole. Recent research suggests that self-compassion is a promising construct for psychologists in terms of its ability to promote psychological wellbeing and resilience to stress; however, the potential benefits of self-compassion are yet to be thoroughly explored amongst this occupational group. Additionally, while a growing body of research supports self-compassion as a key predictor of psychopathology, understanding of the processes by which self-compassion exerts effects on mental health outcomes is limited. Structural equation modelling (SEM) was used to test an emotion regulation model of self-compassion and stress among psychologists, including postgraduate trainees undertaking clinical work (n = 198). Self-compassion significantly negatively predicted emotion regulation difficulties and stress symptoms. Support was also found for our preliminary explanatory model of self-compassion, which demonstrates the mediating role of emotion regulation difficulties in the self-compassion-stress relationship. The final self-compassion model accounted for 26.2% of variance in stress symptoms. Implications of the findings and limitations of the study are discussed.

Responses to and Outcomes of Treatment of Autoimmune Cerebellar Ataxia in Adults.

IMPORTANCE: Classic Purkinje cell cytoplasmic antibody type 1 (PCA-1, or anti-Yo) paraneoplastic cerebellar ataxia has a poor prognosis, yet little has been published otherwise regarding treatment responses and outcomes among patients with autoimmune cerebellar ataxia. OBJECTIVES: To investigate treatment responses and outcomes in adults with autoimmune cerebellar ataxia. DESIGN, SETTING, AND PARTICIPANTS: A cohort study conducted at Mayo Clinic, Rochester, Minnesota, included 118 patients who had ataxia, were 18 years or older, were seropositive for at least 1 neural autoantibody, had received at least 1 immunotherapy or cancer therapy, and had neurologist-reported outcomes documented from January 1, 1989, through December 31, 2013. Data were collected from May 14, 2013, through August 9, 2014, and analyzed from August 9, 2014, through April 27, 2015. Responses to immunotherapy (corticosteroids, intravenous immunoglobulin, plasma exchange, and immunosuppressants) and ambulatory outcomes were compared between different subgroups. Subgroups were classified as paraneoplastic vs nonparaneoplastic disorders; neuronal nuclear and/or cytoplasmic (NNC) antibody positivity vs plasma membrane protein (PMP) antibody positivity; and glutamic acid decarboxylase 65-kDa isoform (GAD65) antibody positivity vs PMP antibody positivity. MAIN OUTCOMES AND MEASURES: Response to therapy and ambulatory ability, with univariate logistic regression and Kaplan-Meier analyses. RESULTS: Inclusion criteria were met by 118 patients. Median age at onset of neurologic symptoms was 58 (range, 27-83) years, and 87 patients (73.7%) were women. Median duration from symptom onset to last follow-up was 25 (range, 2-223) months. Sixty-three patients had paraneoplastic and 55 patients had nonparaneoplastic ataxic disorders. Eighty-one patients were seropositive for NNC antibodies (most commonly PCA-1 [anti-Yo], antineuronal nuclear antibody type 1 [anti-Hu], and GAD65 antibody); 22 patients, for neural PMP receptor or ion channel antibodies (most commonly targeting P/Q- or N-type voltage-gated calcium channels); and 15 patients, for antibodies from both categories. Neurologic improvements occurred in 54 patients (with a robust change in ambulatory ability in 22) attributable to immunotherapy; univariate regression analysis revealed that improvements were significantly more common among patients with nonparaneoplastic disorders (P = .03) and those with exclusively PMP antibodies (P = .02). Kaplan-Meier analyses revealed that progression to wheelchair dependence occurred significantly faster among patients with NNC antibody positivity only (P = .02), although those with GAD65 autoimmunity progressed to wheelchair dependence at a rate similar to those with PMP autoimmunity (P = .92). CONCLUSIONS AND RELEVANCE: Although autoimmune ataxia is usually severe, treatment responses can be gratifying, particularly in patients with nonparaneoplastic disorders and in those harboring autoantibodies directed against GAD65 or neural PMPs.

A small molecule antagonist of the alpha(v)beta3 integrin suppresses MDA-MB-435 skeletal metastasis.

INTRODUCTION: Breast cancer is one of the most common malignancies affecting women in the United States and Europe. Approximately three out of every four women with breast cancer develop metastases in bone which, in turn, diminishes quality of life. The alpha(v)beta3 integrin has previously been implicated in multiple aspects of tumor progression, metastasis and osteoclast bone resorption. Therefore, we hypothesized that the alpha(v)beta3-selective inhibitor, S247, would decrease the development of osteolytic breast cancer metastases. MATERIALS AND METHODS: Cells were treated in vitro with S247 and assessed for viability and adhesion to matrix components. Athymic mice received intracardiac (left ventricle) injections of human MDA-MB-435 breast carcinoma cells expressing enhanced green-fluorescent protein. Mice were treated with vehicle (saline) or S247 (1, 10, or 100 mg/kg/d) using osmotic pumps beginning either one week before or one week after tumor cell inoculation. Bones were removed and examined by fluorescence microscopy and histology. The location and size of metastases were recorded. RESULTS AND CONCLUSIONS: IC50 for S247 adhesion to alpha(v)beta3 or alpha(IIB)beta3a substrates was 0.2 nM vs. 244 nM, respectively. Likewise, S247 was not toxic at doses up to 1000 microM. However, osteoclast cultures treated with S247 exhibited marked morphological changes and impaired formation of the actin sealing zone. When S247 was administered prior to tumor cells, there was a significant, dose-dependent reduction (25-50% of vehicle-only-treated mice; P = 0.002) in osseous metastasis. Mice receiving S247 after tumor cell inoculation also developed fewer bone metastases, but the difference was not statistically significant. These data suggest that, in the MDA-MB-435 model, the alpha(v)beta3 integrin plays an important role in early events (e.g., arrest of tumor cells) in bone metastasis. Furthermore, the data suggest that alpha(v)beta3 inhibitors may be useful in the treatment and/or prevention of breast cancer metastases in bone.
