The Retrograde Memory for News Events Test (RM-NET) and the relationship between news event memory and performance on standard neuropsychological tests.

Novel tests of semantic memory (SM)-for example, memory for news events (NE; news facts) or famous personalities-are useful for estimating the severity of retrograde amnesia. Individuals with mild cognitive impairment exhibit relatively intact SM/language on traditional neuropsychological tests but exhibit consistent impairment on novel tests of SM, suggesting novel SM tests are dissimilar from traditional SM tests. To identify the relationship between NE memory and traditional cognitive measures, older adults (N = 51) completed a traditional neuropsychological battery and the Retrograde Memory News Events Test (RM-NET; a new test that robustly measures NE memory across the adult life span with high temporal resolution), and the relationship between performance on these tests was examined. Total RM-NET scores were more closely aligned with episodic memory scores than SM scores. The strength of the association between NE scores and episodic memory scores decreased as the age of NE memory increased. Tests of news events appear to reflect performance on traditional tests of episodic memory rather than SM, especially when recent news events are tested.

A clinical trial comparing trauma-informed guilt reduction therapy (TrIGR), a brief intervention for trauma-related guilt, to supportive care therapy.

INTRODUCTION: Trauma-related guilt is common, associated with posttraumatic mental health problems, and can persist after posttraumatic stress disorder (PTSD) treatment. We compared the efficacy of two six-session psychotherapies, Trauma-Informed Guilt Reduction (TrIGR) and Supportive Care Therapy (SCT), for reducing trauma-related guilt. TrIGR helps patients accurately appraise their role in the trauma and re-engage in values. In SCT, patients guide session content. METHODS: A total of 184 veterans seeking VA mental health services were enrolled across two sites; 145 veterans (mean age: 39.2 [8.1]; 92.4% male; 84.8% with PTSD) who endorsed guilt related to a traumatic event that occurred during a post 9/11 Iraq or Afghanistan deployment were randomized and assessed at baseline, posttreatment, 3- and 6-month follow-up. RESULTS: Linear mixed models using intent-to-treat analyses showed guilt decreased in both conditions with a greater decrease for TrIGR (treatment × time, -0.22; F 1, 455.2 = 18.49, p = .001; d = 0.92) than supportive therapy. PTSD and depressive symptoms showed the same pattern. TrIGR had significantly higher likelihood of PTSD treatment response (67% vs. 40%), loss of PTSD diagnosis (50% vs. 14%), and meaningful change in depression (54% vs. 27%) than supportive therapy. Psychological distress and trait shame improved in both conditions. Quality of life did not change. CONCLUSIONS: Targeting guilt appears to be an effective means for reducing posttraumatic symptoms and distress.

Severities in persistent mild traumatic brain injury related headache is associated with changes in supraspinal pain modulatory functions.

Emerging evidence suggests mild traumatic brain injury related headache (MTBI-HA) is a form of neuropathic pain state. Previous supraspinal mechanistic studies indicate patients with MTBI-HA demonstrate a dissociative state with diminished levels of supraspinal prefrontal pain modulatory functions and enhanced supraspinal sensory response to pain in comparison to healthy controls. However, the relationship between supraspinal pain modulatory functional deficit and severity of MTBI-HA is largely unknown. Understanding this relationship may provide enhanced levels of insight about MTBI-HA and facilitate the development of treatments. This study assessed pain related supraspinal resting states among MTBI-HA patients with various headache intensity phenotypes with comparisons to controls via functional magnetic resonance imaging (fMRI). Resting state fMRI data was analyzed with self-organizing-group-independent-component-analysis in three MTBI-HA intensity groups (mild, moderate, and severe) and one control group (n = 16 per group) within a pre-defined supraspinal pain network based on prior studies. In the mild-headache group, significant increases in supraspinal function were observed in the right premotor cortex (T = 3.53, p < 0.001) and the left premotor cortex (T = 3.99, p < 0.0001) when compared to the control group. In the moderate-headache group, a significant (T = -3.05, p < 0.01) decrease in resting state activity was observed in the left superior parietal cortex when compared to the mild-headache group. In the severe-headache group, significant decreases in resting state supraspinal activities in the right insula (T = -3.46, p < 0.001), right premotor cortex (T = -3.30, p < 0.01), left premotor cortex (T = -3.84, p < 0.001), and left parietal cortex (T = -3.94, p < 0.0001), and an increase in activity in the right secondary somatosensory cortex (T = 4.05, p < 0.0001) were observed when compared to the moderate-headache group. The results of the study suggest that the increase in MTBI-HA severity may be associated with an imbalance in the supraspinal pain network with decline in supraspinal pain modulatory function and enhancement of sensory/pain decoding.

Real-world characteristics of women with endometriosis-related pain entering a multidisciplinary endometriosis program.

BACKGROUND: Women with endometriosis are commonly treated by their sole provider. In this single-provider model of care, women frequently report long diagnostic delays, unresolved pelvic pain, multiple laparoscopic surgeries, sequential consultations with numerous providers, and an overall dissatisfaction with care. The emergence of multidisciplinary endometriosis centers aims to reduce diagnostic delays, improve pain management, and promote patient satisfaction; however, baseline data at the time of presentation to a multidisciplinary center are lacking. METHODS: A real-world, retrospective, single-site, cross-sectional study of women with surgically confirmed and/or clinically diagnosed endometriosis generated baseline data for a planned longitudinal assessment of multidisciplinary care of endometriosis. The primary objective was to determine the proportion of patients experiencing mild, moderate, or severe pain for dysmenorrhea, non-menstrual pelvic pain (NMPP), and dyspareunia at entry into a multidisciplinary endometriosis clinic. Also explored were relationships between pain scores and clinical endpoints obtained from electronic medical records. RESULTS: More than half (59%) of the study participants (n = 638) reported experiencing pelvic pain for ≥ 5 years. Pain intensity was highest for patients reporting dysmenorrhea, followed by NMPP, and dyspareunia. Significant correlations were observed between total pelvic pain and patient age (r = -0.22, p < 0.001, n = 506) and number of previous healthcare providers (r = 0.16, p = 0.006, n = 292); number of previous providers and duration of pain (r = 0.21, p = < 0.0001, n = 279); and duration of pain and years since diagnosis (r = 0.60, p < 0.001, n = 302). Mean pain scores differed significantly by age group for dysmenorrhea (p < 0.001), NMPP (p = 0.005), and total pelvic pain (p < 0.001), but not for dyspareunia (p = 0.06), with the highest mean pain scores reported among those < 30 years of age. CONCLUSION: These real-world data indicate that in the single-provider model of care, unresolved pelvic pain is common among women with endometriosis. Alternative care models, including a multidisciplinary approach, need to be evaluated for improvements in clinical outcomes. These data also highlight the importance of addressing NMPP, which may be particularly troublesome for patients.

Attitudes on pharmacogenetic testing in psychiatric patients with treatment-resistant depression.

BACKGROUND: Novel technologies make it possible to incorporate pharmacogenetic testing into the medical management of depression. However, previous studies indicate that there may be a subset of subjects who have concerns about genetic testing and may be psychologically vulnerable. If so, pharmacogenetic testing in depressed subjects could negatively impact their mental health and undermine treatment goals. METHODS: In this study, we developed a standardized instrument to assess motivations and attitudes around pharmacogenetic testing in a cohort of 170 depressed Veterans participating in a multi-center clinic trial. RESULTS: Testing reveals that subjects were largely positive about the use of genetic testing to guide pharmacological treatment and help plan their future. Most subjects showed only modest concerns about the impact on family, inability to cope with the results, and fear of discrimination. The severity of depression did not predict the concern expressed about negative outcomes. However, non-Caucasian subjects were more likely on average to endorse concerns about poor coping and fear of discrimination. CONCLUSIONS: These data indicate that while the overall risk is modest, some patients with depression may face psychosocial challenges in the context of pharmacogenetic testing. Future work should identify factors that predict distress and aim to tailor test results to different populations.

Home-based delivery of variable length prolonged exposure therapy: A comparison of clinical efficacy between service modalities.

OBJECTIVE: This study examined clinical and retention outcomes following variable length prolonged exposure (PE) for posttraumatic stress disorder (PTSD) delivered by one of three treatment modalities (i.e., home-based telehealth [HBT], office-based telehealth [OBT], or in-home-in-person [IHIP]). METHOD: A randomized clinical trial design was used to compare variable-length PE delivered through HBT, OBT, or IHIP. Treatment duration (i.e., number of sessions) was determined by either achievement of a criterion score on the PTSD Checklist for Diagnostic and Statistical Manual-5 (DSM-5; PTSD Checklist for DSM-5) for two consecutive sessions or completion of 15 sessions. Participants received PE via HBT (n = 58), OBT (n = 59) or IHIP (n = 58). Data were collected between 2012 and 2018, and PTSD was diagnosed using the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), administered at baseline, posttreatment, and 6 months following treatment completion. The primary clinical outcome was CAPS-5 PTSD severity. Secondary outcomes included self-reported PTSD and depression symptoms, as well as treatment dropout. RESULTS: The clinical effectiveness of PE did not differ by treatment modality across any time point; however, there was a significant difference in treatment dropout. Veterans in the HBT (odds ratio [OR] = 2.67; 95% confidence interval [CI] = 1.10, 6.52; p = .031) and OBT (OR = 5.08; 95% CI = 2.10; 12.26; p < .001) conditions were significantly more likely than veterans in IHIP to drop out of treatment. CONCLUSIONS: Providers can effectively deliver PE through telehealth and in-home, in-person modalities although the rate of treatment completion was higher in IHIP care.

Prevalence of Nonalcoholic Fatty Liver Disease in Children with Obesity.

OBJECTIVES: To determine the prevalence of nonalcoholic fatty liver disease (NAFLD) in children with obesity because current estimates range from 1.7% to 85%. A second objective was to evaluate the diagnostic accuracy of alanine aminotransferase (ALT) for NAFLD in children with obesity. STUDY DESIGN: We evaluated children aged 9-17 years with obesity for the presence of NAFLD. Diseases other than NAFLD were excluded by history and laboratories. Hepatic steatosis was measured by liver magnetic resonance imaging proton density fat fraction. The diagnostic accuracy of ALT for detecting NAFLD was evaluated. RESULTS: The study included 408 children with obesity that had a mean age of 13.2 years and mean body mass index percentile of 98.0. The study population had a mean ALT of 32 U/L and median hepatic magnetic resonance imaging proton density fat fraction of 3.7%. The estimated prevalence of NAFLD was 26.0% (95% CI 24.2%-27.7%), 29.4% in male patients (CI 26.1%-32.7%) and 22.6% in female patients (CI 16.0%-29.1%). Optimal ALT cut-point was 42 U/L (47.8% sensitivity, 93.2% specificity) for male and 30 U/L (52.1% sensitivity, 88.8% specificity) for female patients. The classification and regression tree model with sex, ALT, and insulin had 80% diagnostic accuracy for NAFLD. CONCLUSIONS: NAFLD is common in children with obesity, but NAFLD and obesity are not concomitant. In children with obesity, NAFLD is present in nearly one-third of boys and one-fourth of girls.

Compassion Meditation for Posttraumatic Stress Disorder in Veterans: A Randomized Proof of Concept Study.

There is considerable interest in developing complementary and integrative approaches for ameliorating posttraumatic stress disorder (PTSD). Compassion meditation (CM) and loving-kindness meditation appear to offer benefits to individuals with PTSD, including symptom reduction. The present study was a pilot randomized controlled trial of CM for PTSD in veterans. The CM condition, an adaptation of Cognitively-Based Compassion Training (CBCT®), consists of exercises to stabilize attention, develop present-moment awareness, and foster compassion. We compared CM to Veteran.calm (VC), which consists of psychoeducation about PTSD, rationale for relaxation, relaxation training, and sleep hygiene. Both conditions consist of 10 weekly 90-min group sessions with between-session practice assignments. A total of 28 veterans attended at least one session of the group intervention and completed pre- and posttreatment measures of PTSD severity and secondary outcomes as well as weekly measures of PTSD, depressive symptoms, and positive and negative emotions. Measures of treatment credibility, attendance, practice compliance, and satisfaction were administered to assess feasibility. A repeated measures analysis of variance revealed a more substantive reduction in PTSD symptoms in the CM condition than in the VC condition, between-group d = -0.85. Credibility, attendance, and satisfaction were similar across CM and VC conditions thus demonstrating the feasibility of CM and the appropriateness of VC as a comparison condition. The findings of this initial randomized pilot study provide rationale for future studies examining the efficacy and effectiveness of CM for veterans with PTSD.

Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) Meditación de compasión para el trastorno de estrés postraumático en veteranos: un estudio aleatorio de prueba de concepto MEDITACIÓN DE COMPASIÓN PARA EL TEPT Existe un interés considerable en desarrollar enfoques complementarios e integrativos para mejorar el trastorno de estrés postraumático (TEPT). La meditación de compasión (CM en su sigla en inglés) y la meditación de bondad amorosa (LKM, en su sigla en inglés) parecen ofrecer beneficios a las personas con trastorno de estrés postraumático, incluida la reducción de síntomas. El presente estudio fue un ensayo piloto controlado aleatorizado de CM para el TEPT en veteranos. La condición de CM, una adaptación del entrenamiento de compasión de base cognitiva (CBCT® en sus siglas en inglés), consiste en ejercicios para estabilizar la atención, desarrollar la conciencia del momento presente y fomentar la compasión. Comparamos CM con Veteran.calm (VC en sus siglas en inglés), que consiste en psicoeducación sobre el TEPT y las razones para la relajación, entrenamiento de relajación e higiene del sueño. Ambas condiciones consisten en 10 sesiones de grupo semanales de 90 minutos con tareas de práctica entre sesiones. Un total de 28 veteranos asistieron al menos a una sesión de la intervención grupal y completaron las medidas previas y posteriores al tratamiento de la gravedad del TEPT y resultados secundarios, así como las medidas semanales de TEPT, síntomas depresivos y emociones positivas y negativas. Las medidas de credibilidad del tratamiento, asistencia, cumplimiento de la práctica y satisfacción se administraron para evaluar la viabilidad. Un análisis de la varianza de medidas repetidas reveló una reducción más sustancial en síntomas de TEPT en la condición de CM que en la condición de VC, d de Cohen = -0.85 entre grupos. La credibilidad, la asistencia y la satisfacción fueron similares en todas las condiciones de CM y VC y demostraron la viabilidad de CM y la idoneidad de VC como condición de comparación. Los hallazgos de este estudio piloto aleatorizado inicial proporcionan una base para futuros estudios que examinan la eficacia y la efectividad de CM para los veteranos con TEPT.

Dietary restraint and weight loss in relation to disinhibited eating in obese Veterans following a behavioral weight loss intervention.

Ability to restrain one's dietary intake is a necessary skill for weight loss. However, dietary restraint has been shown to paradoxically increase disinhibited eating in certain populations, thereby negatively impacting weight loss and leading to worse overall health outcomes. The aim of this study was to address gaps in the literature regarding the relationships between separate facets of dietary restraint (intention; behavior) with weight loss and various types of disinhibited eating (binge eating, external eating, emotional eating) in overweight and obese adults who recently completed a weight loss intervention. A sample of mostly male Veterans with overweight and obesity (N = 88) self-reported their dietary restraint intention, restraint behavior, and current disinhibited eating following completion of an 8-week behavioral weight loss treatment. Greater dietary restraint intention was related to greater dietary restraint behavior, p < .05. Greater dietary restraint behavior was significantly related to greater recent weight loss, p < .05, while restraint intention was not, p > .05. Greater dietary restraint intention was related to greater current binge eating and external eating, while greater self-reported restraint behavior was related to less binge eating, p < .05. Thus, dietary restraint behavior appears to be adaptive for this population, whereas rigid dietary restraint intention may increase risk for disinhibited eating. To decrease disinhibited eating and improve weight loss outcomes in Veterans, interventions might specifically address rigid rule-following associated with abandonment of weight loss goals and help Veterans develop specific yet flexible eating plans. Future research should examine whether dietary restraint intention and behavior differentially predict disinhibited eating and weight loss outcomes prospectively.

Emotion regulation mediates the relationship between verbal learning and internalizing, trauma-related and externalizing symptoms among early-onset, persistently delinquent adolescents.

Research supports cascading relationships among internalizing and externalizing symptoms, and academic problems. This constellation of problems characterizes Early-Onset/Persistent Delinquent [EOPD] youth and appropriately targeted interventions accounting for this comorbidity may improve outcomes. To investigate these relationships in EOPD youth, we characterized their cross-diagnostic psychopathology and verbal (word-list) learning/memory and evaluated: 1) verbal learning/memory profiles of Withdrawn/Depressed relative to Non-Withdrawn/Depressed youth; 2) cognitive and psychiatric predictors of verbal learning; and 3) emotion regulation as a mediator of psychiatric and cognitive relationships. Results indicated Withdrawn/Depressed youth recalled significantly fewer words during immediate, and some delayed, recall conditions. Less word-learning was predicted by: Withdrawn/Depressed classification, higher trauma-specific re-experiencing symptoms, greater emotion dysregulation, weaker executive skills, fewer trauma-avoidance and aggressive symptoms, and earlier alcohol-use onset. Emotion regulation strongly mediated the relationship between verbal learning and psychopathology, but not cognitive skills, among youth at high-risk for school dropout. Mental health and education implications are discussed.

Multimedia Aided Consent for Alzheimer's Disease Research.

OBJECTIVES: Optimizing the research consent process simultaneously fosters respect for autonomy and protection of those with diminished capacity for autonomy. This study evaluated the effectiveness of an enhanced research consent procedure, employing multimedia disclosure and corrective feedback, in improving decisional capacity among 114 people with mild-to-moderate Alzheimer's disease (AD) and 134 non-psychiatric comparison (NC) subjects. METHODS: Participants were randomized to consent type (routine versus enhanced) and protocol type (lower versus higher risk). Outcomes included a 5-item questionnaire assessing immediate comprehension, MacArthur Competence Assessment Tool for Clinical Research assessing four components of decision-making capacity, and categorical decisional capacity (based on a cut-score established in reference to expert judgments for a subset of participants). RESULTS: There was no significant effect of the enhanced consent procedure, relative to routine consent, on immediate comprehension or decisional capacity. CONCLUSIONS: Multimedia tools do not appear to be the solution to better consent for AD research. CLINICAL IMPLICATIONS: Given the ethical primacy of informed consent and issues of justice for impaired populations who might be harmed by an absence of research-based treatment advances, continued search for ways to more meaningfully engage people with AD in the consent or assent process is warranted.

Mental Health Does Not Moderate Compensatory Cognitive Training Efficacy for Veterans With a History of Mild Traumatic Brain Injury.

OBJECTIVE: To examine the potential moderating effects of mental health symptoms on the efficacy of compensatory cognitive training (CCT) for Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn veterans with a history of mild traumatic brain injury (mTBI). DESIGN: Secondary analysis of a randomized controlled trial of CCT. Posttraumatic stress disorder, depression, and substance dependence symptom severity were examined as potential moderators of CCT efficacy for subjective cognitive complaints, use of cognitive strategies, and objective neurocognitive performance. SETTING: Three Veterans Affairs medical centers. PARTICIPANTS: Participants included veterans with history of mTBI (N=119): 50 participated in CCT and 69 received usual care (UC). INTERVENTION: CCT is a 10-week group-based (90 minutes per session) manualized cognitive rehabilitation intervention. MAIN OUTCOME MEASURES: Objective (neuropsychological functioning) and subjective (self-report) cognitive functioning and use of cognitive strategies. RESULTS: Baseline mental health symptoms did not moderate CCT efficacy: veterans who received CCT reported significantly greater improvement in cognitive difficulties and use of cognitive strategies compared with the UC group, regardless of baseline mental health symptom severity. The CCT group also demonstrated significant improvements on neuropsychological measures of attention, learning, and executive functioning compared with the UC group, regardless of baseline mental health symptom severity. CONCLUSIONS: CCT is efficacious for improving objective cognitive functioning and compensatory strategy use for veterans with a history of mTBI, regardless of the severity of comorbid psychiatric symptoms.

Compensatory Cognitive Training for Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn Veterans With Mild Traumatic Brain Injury.

OBJECTIVE: The purpose of the study was to evaluate the efficacy of group-based compensatory cognitive training (CCT) for Operation Enduring Freedom (OEF)/Operation Iraqi Freedom(OIF)/Operation New Dawn (OND) Veterans with a history of mild traumatic brain injury. METHOD: One hundred nineteen OEF/OIF/OND Veterans with history of mild traumatic brain injury participated at 3 sites, and 50 of the Veterans were randomized to CCT group, while 69 Veterans were randomized to the usual care control group. The CCT group participated in 10 weeks of CCT. Both CCT and usual care groups were assessed at baseline, 5 weeks (midway through CCT), 10 weeks (immediately following CCT), and 15 weeks (5-week follow-up) on measures of subjective cognitive complaints, use of cognitive strategies, psychological functioning, and objective cognitive performance. RESULTS: Veterans who participated in CCT reported significantly fewer cognitive and memory difficulties and greater use of cognitive strategies. They also demonstrated significant improvements on neurocognitive tests of attention, learning, and executive functioning, which were 3 of the cognitive domains targeted in CCT. CONCLUSIONS: Findings indicate that training in compensatory cognitive strategies facilitates behavioral change (ie, use of cognitive strategies) as well as both subjective and objective improvements in targeted cognitive domains.

Repetitive Transcranial Magnetic Stimulation in Managing Mild Traumatic Brain Injury-Related Headaches.

OBJECTIVE: Headache is one of the most common debilitating chronic pain conditions in either active or retired military personnel with mild traumatic brain injury (MTBI). This study assessed the effect of repetitive transcranial magnetic stimulation (rTMS) in alleviating MTBI-related headache (MTBI-HA). MATERIALS AND METHOD: Veterans with MTBI-HA were randomized to receive either real rTMS (REAL group) at 10 hz for a total of 2000 pulses divided into 20 trains with one-sec inter-train interval or sham rTMS (SHAM group) at the left motor cortex (LMC) with brain magnetic resonance imaging neuronavigation guidance. Pretreatment, posttreatment one-week and four-week headache and neuropsychological assessments were conducted. RESULT: Thirty veterans were screened and twenty four (21 men and 3 women with average year-old ± SD at 14.3 ± 12.6) subjects' data were analyzed. A two-factor (visit × treatment) repeated measures analysis of variance (RM-ANOVA) indicated a close to significant (p = 0.06) trend of interaction between pretreatment and posttreatment one-week assessment with the intensity of the persistent daily headache decreasing from 5.7 ± 1.9 to 2.2 ± 2.7 and 4.6 ± 1.3 to 3.5 ± 2.0 for the REAL and SHAM groups, respectively. Subsequent analyses indicated REAL group demonstrated a significantly (p = 0.041) higher % of reduction in persistent headache intensity than the SHAM group (56.3 ± 48.2% vs.15.4 ± 43.6%) at the posttreatment one-week assessment and the trend continued to the four-week assessment. Overall, a significantly (p = 0.035) higher percentage of the subjects in the REAL group (58.3%) demonstrated at least a 50% headache intensity reduction at posttreatment one-week assessment compared with the SHAM group (16.6%). The overall composite score of functionally debilitating headache exacerbation is significantly (p = 0.017) reduced in REAL group at the posttreatment four-week assessment in comparison with the SHAM group. No major sustained change in neuropsychological assessments was noted. CONCLUSION: The studied rTMS protocol appears to be a clinically feasible and effective treatment option in managing MTBI-HA.

From suffering to caring: a model of differences among older adults in levels of compassion.

OBJECTIVE: Compassion is an important contributor to pro-social behavior and maintenance of interpersonal relationships, yet little is known about what factors influence compassion in late life. The aim of this study was to test theories about how past and current stressors and emotional functioning, resilience, and demographic indicators of life experiences are related to compassion among older adults. METHODS: One thousand and six older adults (50-99 years) completed a comprehensive survey including self-report measures of compassion, resilience, past and present stress, and emotional functioning (i.e., stressful life events, perceived stress, and current and prior depression and anxiety), and demographic information. The sample was randomly split, and exploratory and confirmatory regression analyses were conducted testing hypothesized relationships with compassion. RESULTS: Exploratory stepwise regression analysis (n = 650) indicated that participants who reported higher levels of compassion were more likely to be female, not currently in a married/married-like relationship, reported higher resilience levels, and had experienced more significant life events. Age, income level, past and current mental distress, and interactions between resilience and other predictors were not significantly related to compassion. The associations between greater self-reported compassion and being female, having greater resilience, and having experienced more significant life events were supported by a confirmatory stepwise regression analysis (n = 356). CONCLUSIONS: Older women report more compassion than older men. Resilience and significant life events, independently, also appear to facilitate a desire to help others, while current stress and past and present emotional functioning are less relevant. Specificity of findings to older adults is not yet known.

Effect of low frequency transcutaneous magnetic stimulation on sensory and motor transmission.

Peripheral nerve injury diminishes fast conducting large myelinated afferent fibers transmission but enhances smaller pain transmitting fibers firing. This aberrant afferent neuronal behavior contributes to development of chronic post-traumatic peripheral neuropathic pain (PTP-NP). Non-invasive dynamic magnetic flux stimulation has been implicated in treating PTP-NP, a condition currently not adequately addressed by other therapies including transcutaneous electrical nerve stimulation (TENS). The current study assessed the effect of low frequency transcutaneous magnetic stimulation (LFTMS) on peripheral sensory thresholds, nerve conduction properties, and TENS induced fast afferent slowing effect as measured by motor and sensory conduction studies in the ulnar nerve. Results indicated sham LFTMS with TENS (Sham + TENS) significantly (P = 0.02 and 0.007, respectively) reduces sensory conduction velocity (CV) and increases sensory onset latency (OL), and motor peak latency (PL) whereas, real LFTMS with TENS (Real + TENS) reverses effects of TENS on sensory CV and OL, and significantly (P = 0.036) increases the sensory PL. LFTMS alone significantly (P < 0.05) elevates sensory PL and onset-to-peak latency. LFTMS appears to reverse TENS slowing effect on fast conducting fibers and casts a selective peripheral modulatory effect on slow conducting pain afferent fibers.

Enhancing legacy in palliative care: study protocol for a randomized controlled trial of Dignity Therapy focused on positive outcomes.

BACKGROUND: Dignity Therapy is a brief psychotherapy that can enhance a sense of legacy while addressing the emotional and existential needs of patients receiving hospice or palliative care. In Dignity Therapy, patients create a formalized "legacy" document that records their most cherished memories, their lessons learned in life, as well as their hopes and dreams for loved ones in the future. To date, this treatment has been studied for its impact on mitigating distress within hospice and palliative care populations and has provided mixed results. This study will instead focus on whether Dignity Therapy enhances positive outcomes in this population. METHODS/DESIGN: In this study, 90 patients with cancer receiving hospice or palliative care will complete a mixed-methods randomized controlled trial of Dignity Therapy (n = 45) versus Supportive Attention (n = 45). The patients will be enrolled in the study for 3 weeks, receiving a total of six study visits. The primary outcomes examine whether the treatment will quantitatively increase levels of positive affect and a sense of life closure. Secondary outcomes focus on gratitude, hope, life satisfaction, meaning in life, resilience, and self-efficacy. Using a fixed, embedded dataset design, this study will additionally use qualitative interviews to explore patients' perceptions regarding the use of positive outcome measures and whether these outcomes are appropriately matched to their experiences in therapy. DISCUSSION: Dignity Therapy has shown mixed results when evaluating its impact on distress, although no other study to date has solely focused on the potential positive aspects of this treatment. This study is novel in its use of mixed methods assessments to focus on positive outcomes, and will provide valuable information about patients' direct experiences in this area. TRIAL REGISTRATION: ISRCTN91389194.

Does age moderate the relationship between depressive symptoms and suicidal ideation in middle-aged and older patients with schizophrenia and subthreshold depression?

BACKGROUND: Suicidal deaths in middle-aged and older individuals with schizophrenia are a public health concern. Depression and schizophrenia are major risk factors for suicide. However, it is unknown whether age moderates the relationship between depression and suicidal ideation in patients with schizophrenia and subthreshold depression. METHODS: Suicidal ideation was assessed with the InterSePT Scale for Suicidal Ideation and the Clinical Global Impression-Suicide Severity Scale in outpatients older than 39 years with schizophrenia and subthreshold depression (n = 213). Using linear regression, we examined whether depression (based on Calgary Depression Rating Scale scores), age, and "age by depressive symptoms" predicted suicidal ideation. RESULTS: Depressive symptoms predicted suicidal ideation. Neither age nor "depressive symptoms by age" predicted suicidal ideation. CONCLUSIONS: In this population, age does not appear to moderate the relationship between depressive symptoms and suicidal behavior. Thus, assessing depressive symptoms as a risk factor is important at all ages in this population.

News event memory in amnestic and non-amnestic MCI, heritable risk for dementia, and subjective memory complaints.

Robust and sensitive clinical measures are needed for more accurate and earlier detection of Alzheimer's disease (AD), for staging preclinical AD, and for gauging the efficacy of treatments. Mild impairment on episodic memory tests is thought to indicate a cognitive risk of developing AD and mild cognitive impairment (MCI), considered to be a transitional stage between normal aging and AD. Novel tests of semantic memory, such as memory for news events, are also impaired early on but have received little clinical attention even though they may provide a novel way to assess cognitive risk for AD. We examined memory for news events in older adults with normal cognition (NC, N = 34), amnestic MCI (aMCI, N = 27), or non-aMCI (N = 10) using the Retrograde Memory News Events Test (RM-NET). We asked if news event memory was sensitive to 1) aMCI and also non-aMCI, which has rarely been examined, 2) genetic risk for dementia (positive family history of any type of dementia, presence of an APOE-4 allele, or polygenic risk for AD), and 3) subjective memory functioning judgments about the past. We found that both MCI subgroups exhibited impaired RM-NET Lifespan accuracy scores together with temporally-limited retrograde amnesia. For the aMCI group amnesia extended back 45 years prior to testing, but not beyond that time frame. The extent of retrograde amnesia could not be reliably estimated in the small non-aMCI group. The effect sizes of having MCI on the RM-NET were medium for the non-aMCI group and large for the aMCI group, whereas the effect sizes of participant characteristics on RM-NET accuracy scores were small. For the combined MCI group (N = 37), news event memory was significantly related to positive family history of dementia but was not related to the more specific genetic markers of AD risk. For the NC group, news event memory was not related to any measure of genetic risk. Objective measures of past memory from the RM-NET were not related to subjective memory judgements about the present or the recent past in either group. By contrast, when individuals subjectively compared their present versus past memory abilities, there was a significant association between this judgment and objective measures of the past from the RM-NET (direct association for the NC group and inverse for the MCI group). The RM-NET holds significant promise for early identification of those with cognitive and genetic risk factors for AD and non-AD dementias.

An evaluation of treatment response and remission definitions in adult obsessive-compulsive disorder: A systematic review and individual-patient data meta-analysis.

INTRODUCTION: Expert consensus operationalized treatment response and remission in obsessive-compulsive disorder (OCD) as a Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) reduction ≥35% and score ≤12 with ≤2 on Clinical Global Impressions Improvement (CGI-I) and Severity (CGI-S) scales, respectively. However, there has been scant empirical evidence supporting these definitions. METHODS: We conducted a systematic review and an individual participant data meta-analysis of randomized-controlled trials (RCTs) in adults with OCD to determine optimal Y-BOCS thresholds for response and remission. We estimated pooled sensitivity/specificity for each percent reduction threshold (response) or posttreatment score (remission) to determine response and remission defined by a CGI-I and CGI-S ≤ 2, respectively. RESULTS: Individual participant data from 25 of 94 eligible RCTs (1235 participants) were included. The optimal threshold for response was ≥30% Y-BOCS reduction and for remission was ≤15 posttreatment Y-BOCS. However, differences in sensitivity and specificity between the optimal and nearby thresholds for response and remission were small with some uncertainty demonstrated by the confidence ellipses. CONCLUSION: While the empirically derived Y-BOCS thresholds in our meta-analysis differ from expert consensus, given the predominance of data from more recent trials of OCD, which involved more refractory participants and novel treatment modalities as opposed to first-line therapies, we recommend the continued use of the consensus definitions.
