Abstract | Introduction: Cancer patients have significant levels of emotional distress. The National Comprehensive Cancer Network (NCCN) developed the distress management tool to quickly assess significant distress in oncological patients who require intervention. For its use in Colombia, we made its cross-cultural adaptation and validation. Objective: To determine the operative characteristics of the distress management tool, version 2.2018, in patients seen at the Instituto Nacional de Cancerología (INC) in Colombia. Materials and methods: Counting with the authorization from the NCCN, we translated, made the cross-cultural adaptation, and evaluated the operational characteristics of the tool. We included 343 cancer patients seen at the INC, who filled out the cross-culturally adapted instrument. A diagnostic test study was carried out with a semi-structured interview as a reference. Results: The patients had an average age of 49.7 years (SD=15) and the majority were women (67%). The instrument had an area under the ROC curve of 0.81 (95% CI: 0.77 - 0.86); its optimal cut-off point was 3.5 approached to 4 when using integers on the scale; its sensitivity was 0.81 (95% CI: 0.76 - 0.85), and its specificity, 0.69 (95% CI: 0.64 - 0.74). The agreement percentage between the result of the interview and the instrument was 73% (kappa = 0.64; p< 0.001). Conclusions: The distress management tool allowed for the detection of moderate to severe distress requiring intervention and management. This instrument was adapted and validated in cancer patients in Colombia keeping the cutoff point at ≥ 4 as in the original version.

BACKGROUND: Delirium is an acute disorder of attention and cognition that is common, serious, costly, under-recognized, and potentially fatal. Delirium is particularly problematic in the emergency department (ED) care of medically complex older adults, who are being seen in greater numbers. OBJECTIVE: This evidence-based narrative review focuses on the key components of delirium screening, prevention, and treatment. DISCUSSION: The recognition of delirium requires a systematic approach rather than a clinical gestalt alone. Several delirium assessment tools with high sensitivity and specificity, such as delirium triage screen and brief Confusion Assessment Method, can be used in the ED. The prevention of delirium requires environmental modification and unique geriatric care strategies tailored to the ED. The key approaches to treatment include the removal of the precipitating etiology, re-orientation, hydration, and early mobilization. Treatment of delirium requires a multifaceted and comprehensive care plan, as there is limited evidence for significant benefit with pharmacological agents. CONCLUSION: Older ED patients are at high risk for current or subsequent development of delirium, and a focused screening, prevention, and intervention for those who are at risk for delirium and its associated complications are the important next steps.

OBJECTIVE: When considering psychosis, the concept of narrative insight has been offered as an alternative to clinical insight in determining individuals' responses to their difficulties, as it allows for a more holistic and person-centred framework to be embraced within professional practice. This study aims to explore the validity of the narrative insight construct within a group of people who have experienced psychosis. DESIGN: Inductive qualitative methods were used to explore how eight participants utilized spiritual or religious explanatory frameworks for their experiences of psychosis and to consider these in relation to the construct of narrative insight. METHODS: Semi-structured interviews were undertaken with individuals who identified themselves as interested in spiritual or religious ideas and whose self-reported experiences which were identified as akin to psychosis by experienced academic clinicians. Transcriptions from these interviews were subject to interpretative phenomenological analysis within a broader research question; a selection of themes and data from the resultant phenomenological structure are explored here for their relevance to narrative insight. RESULTS: Participants discussed spiritual and biological explanations for their experiences and were able to hold alternative potential explanations alongside each other. They were reflective regarding the origins of their explanations and would describe a process of testing and proof in relation to them. CONCLUSIONS: These findings suggest that the narrative insight construct has the potential to be a valid approach to understanding experiences of psychosis, and challenge the dominance of the clinical insight construct within clinical practice. PRACTITIONER POINTS: Clinicians should value the explanatory framework for experiences which are provided by individuals experiencing psychosis, and encourage them to develop a framework which is coherent to their own world view rather than predominantly pursuing a biomedical explanation. Assessments of psychosis should be adapted to include an understanding of the cohesiveness of the individual's explanatory framework and personal value to them, with a reduced focus on their acceptance of biomedical models of 'illness'. Care and care research for individuals experiencing psychosis should consider the value of narrative insight within future developments.

INTRODUCTION: Benzodiazepines and related drugs (BZDR) should be avoided in patients with cognitive impairment. We evaluated the relationship between a BZDR treatment and the health status of patients with Alzheimer's disease (AD). METHODS: Cross-sectional study in 395 AD patients using bivariate and multiple logistic analyses to assess correlations between the prescription of BZDR and patients' characteristics (cognitive and functional capacity, health-related quality of life (HrQoL), neuropsychiatric symptoms). RESULTS: BZDR were used in 12.4% (n=49) of all participants. In bivariate analyses, the prescription was associated with a lower HrQoL, a higher need of care, and the presence of anxiety. Multivariate models revealed a higher risk of BZDR treatment in patients with depression (OR 3.85, 95% CI: 1.45 - 10.27). Community-dwelling participants and those treated by neurologists/psychiatrists had a lower risk of receiving BZDR (OR 0.33, 95% CI: 0.12 - 0.89 and OR 0.16, 95% CI: 0.07 - 0.36). DISCUSSION: The inappropriate use of BZDR conflicts with national and international guidelines. We suggest evaluating indications and treatment duration and improving the knowledge of alternative therapies in healthcare institutions.

OBJECTIVE: To explore the potential factors that mediate the relationship between mindfulness and symptoms of posttraumatic stress (PTS) in women who experienced stillbirth. DESIGN: A cross-sectional analysis of baseline data before women's participation in an online mindfulness intervention (i.e., online yoga). SETTING: This was a national study, and women participated in their own homes. PARTICIPANTS: Women who experienced stillbirth (N = 74) within the past 2 years and resided in the United States. METHODS: Women were recruited nationally, primarily through social media. Participants (N = 74) completed baseline assessments (self-report mental and physical health surveys) via a Web-based survey tool. We conducted an exploratory factor analysis of the COPE Inventory subscales to reduce the number of variables before entry into a mediation model. We then tested the mediation effects of sleep quality, self-esteem, resilience, and maladaptive coping on the relationship between mindfulness and PTS symptoms. RESULTS: Through the exploratory factor analysis we identified a two-factor solution. The first factor included nine subscales that represented adaptive coping strategies, and the second factor included five subscales that represented maladaptive coping strategies. Results from multiple mediation analysis suggested that mindfulness had a significant inverse relationship to PTS symptoms mediated by sleep quality. CONCLUSION: Mindfulness practices may have potential benefits for grieving women after stillbirth. Evidence-based approaches to improve sleep quality also may be important to reduce PTS symptoms in women after stillbirth.

BACKGROUND: Dysbiosis of intestinal microbiota in the elderly can cause a leaky gut, which may result in silent systemic inflammation and promote neuroinflammation - a relevant pathomechanism in the early course of Alzheimer's disease. OBJECTIVE: The rebalancing of the microbiome could benefically impact on gut inflammation and immune activation. METHODS: In this study, routine laboratory tests in twenty outpatients (9 females, 11 males, aged 76.7 ± 9.6 years) with Alzheimer's disease were investigated. The mean Mini Mental State Examination score was 18.5 ± 7.7. Biomarkers of immune activation - serum neopterin and tryptophan breakdown - as well as gut inflammation markers and microbiota composition in fecal specimens were analyzed in 18 patients before and after probiotic supplementation for 4 weeks. RESULTS: After treatment a decline of fecal zonulin concentrations and an increase in Faecalibacterium prausnitzii compared to baseline were observed. At the same time, serum kynurenine concentrations increased (p <0.05). Delta values (before - after) of neopterin and the kynurenine to tryptophan ratios (Kyn/Trp) correlated significantly (p <0.05). CONCLUSION: Results show that the supplementation of Alzheimer's disease patients with a multispecies probiotic influences gut bacteria composition as well as tryptophan metabolism in serum. The correlation between Kyn/Trp and neopterin concentrations points to the activation of macrophages and/or dendritic cells. Further studies are warranted to dissect the potential consequences of Probiotic supplementation in the course of Alzheimer's disease.

BACKGROUND: A growing body of scientific evidence suggests that enrichment of certain nutritional compounds in the brain may reduce the risk of Alzheimer's disease (AD). OBJECTIVE: To investigate the impact of supplemental xanthophyll carotenoids plus omega-3 fatty acids on disease progression in patients with AD. METHODS: Three trial experiments were performed. In Trials 1 and 2 (performed on patients with AD over an 18-month period), 12 patients (AD status at baseline: 4 mild and 8 moderate) were supplemented with a xanthophyll carotenoid only formulation (Formulation 1; lutein:meso-zeaxanthin:zeaxanthin 10:10:2âmg/day) and 13 patients (AD status at baseline: 2 mild, 10 moderate, and 1 severe) were supplemented with a xanthophyll carotenoid and fish oil combination (Formulation 2; lutein:meso-zeaxanthin:zeaxanthin 10:10:2âmg/day plus 1âg/day of fish oil containing 430âmg docohexaenoic acid [DHA] and 90âmg eicopentaenoic acid [EPA]), respectively. In Trial 3, 15 subjects free of AD (the control group) were supplemented for 6 months with Formulation 1. Blood xanthophyll carotenoid response was measured in all trials by HPLC. Omega-3 fatty acids were profiled by direct infusion mass spectrometry. RESULTS: Xanthophyll carotenoid concentration increases were significantly greater for Formulation 2 compared to Formulation 1 (pâ<â0.05), and progression of AD was less for this group (pâ=â0.003), with carers reporting functional benefits in memory, sight, and mood. CONCLUSION: This preliminary report suggests positive outcomes for patients with AD who consumed a combination of xanthophyll carotenoids plus fish oil, but further study is required to confirm this important observation.

BACKGROUND: In moderately advanced Parkinson's disease (PD), low serum vitamin B12 levels are common and are associated with neuropathy and cognitive impairment. However, little is known about B12 in early PD. OBJECTIVE: To determine the prevalence of low vitamin B12 status in early PD and whether it is associated with clinical progression. METHODS: We measured vitamin B12 and other B12 status determinants (methylmalonic acid, homocysteine, and holotranscobalamin) in 680 baseline and 456 follow-up serum samples collected from DATATOP participants with early, untreated PD. Borderline low B12 status was defined as serum B12 <184 pmol/L (250 pg/mL), and elevated homocysteine was defined as >15 µmol/L. Outcomes included the UPDRS, ambulatory capacity score (sum of UPDRS items 13-15, 29&30), and MMSE, calculated as annualized rates of change. RESULTS: At baseline, 13% had borderline low B12 levels, 7% had elevated homocysteine, whereas 2% had both. Elevated homocysteine at baseline was associated with worse scores on the baseline MMSE. Analysis of study outcomes showed that compared with the other tertiles, participants in the low B12 tertile (<234 pmol/L; 317 pg/mL) developed greater morbidity as assessed by greater annualized worsening of the ambulatory capacity score. Elevated homocysteine was associated with greater annualized decline in MMSE (-1.96 vs. 0.06; P = 0001). Blood count indices were not associated with B12 or homocysteine status. CONCLUSIONS: In this study of early PD, low B12 status was common. Low B12 at baseline predicted greater worsening of mobility whereas elevated homocysteine predicted greater cognitive decline. Given that low B12 and elevated homocysteine can improve with vitamin supplementation, future studies should test whether prevention or early correction of these nutritionally modifiable conditions slows development of disability. © 2018 International Parkinson and Movement Disorder Society.

Objectives: To determine the relevance of Mini-Mental State Examination (MMSE), serum 25-hydroxyvitamin D (25(OH)D3), and 1,25(OH)2D3 concentrations to mild cognitive impairment (MCI) and various stages of Alzheimer's disease (AD). Materials and Methods: The study included 230 participants (>74 years) allocated to three main groups: 1-healthy subjects (HS, n = 61), 2-patients with MCI (n = 61), and 3- patients with Alzheimer's disease (AD) subdivided into three stages: mild (n = 41), moderate (n = 35), and severe AD (n = 32). The cognitive status was evaluated using MMSE. Serum 25 (OH)D3 (ng/ml) and 1,25(OH)2D3 concentrations (pg/ml) were determined by competitive radioimmunoassay. Results: MMSE scores and 25(OH)D3 were decreased in MCI and all stages of the AD in both genders. MMSE variability was due to gender in HS (11%) and to 25(OH)D3 in MCI (15%) and AD (26%). ROC analysis revealed an outstanding property of MMSE in diagnosis of MCI (AUC, 0.906; CI 95%, 0.847-0.965; sensitivity 82%; specificity, 98%) and AD (AUC, 0.997; CI 95%, 0.992-1; sensitivity, 100%; specificity, 98%). 25(OH)D3 exhibited good property in MCI (AUC, 0.765; CI 95%, 0.681-0.849; sensitivity, 90%; specificity, 54%) and an excellent property in diagnosis of AD (AUC, 0.843; CI 95%, 0.782-0.904; sensitivity, 97%; specificity, 79%). Logistic analyses revealed that, in MCI, MMSE could predict (or classify correctly) with 97.6% accuracy (Wald, 15.22, ß, -0.162; SE, 0.554; OR = 0.115:0.039-0.341; p = .0001), whereas 25(OH)D3 with 80% accuracy (Wald, 41,013; ß, -0.213; SE, 0.033; OR = 0.808: 0.757-863; p = .0001). 25(OH)D3 was the only significant predictor for the severe AD and contributed to MMSE variability. Age and gender were significant predictors only in the moderate AD. In patients with MCI, 25(OH)D3 and 1,25(OH)2D3 were correlated men, but in case of the AD, they were correlated in women. Conclusions: MMSE and serum 25(OH)D3 concentrations could be useful biomarkers for prediction and diagnosis of MCI and various stages of the AD. The results support the utility of vitamin D supplementation in AD therapy regimen.

OBJECTIVE: Autonomy in patients with Alzheimer's disease (AD) in daily life depends on the preservation of neurocognitive and motor abilities, which decline over time. So far, very few studies have investigated motor representations and their contribution to perception and cognition in AD. METHODS: In the present study, we compared the performance of AD patients to age-matched healthy participants in perceptual and cognitive tasks involving motor imagery. Experiment 1 tested explicit motor and visual imagery through an imagined movement task. Experiment 2 tested body-centred implicit motor imagery through a mental rotation of visual hand task. Finally, Experiment 3 tested object-centred implicit motor imagery through a reachability judgment task. RESULTS: The results showed that, compared to age-matched controls, conscious imagination of a body movement or the movement of a visual stimulus was much longer in AD patients, with no specific difficulty in the motor condition (Experiment 1). Furthermore, response time in AD patients was strongly affected by the angle of rotation of the visual stimuli in the mental rotation of hand task (Experiment 2). Likewise, response time in AD patients increased substantially in the reachability judgment task, but predominantly for stimuli located at the boundary of peripersonal space (Experiment 3). CONCLUSION: As a whole, the data suggested a decline in AD of implicit, but not explicit, motor imagery capacities affecting processing time, but not performance accuracy, in motor-related perceptual and cognitive tasks.

OBJECTIVE: To compare the effects of 2 forms of exercise, i.e., a 6-week trial of treadmill training with virtual reality (TT + VR) that targets motor and cognitive aspects of safe ambulation and a 6-week trial of treadmill training alone (TT), on brain activation in patients with Parkinson disease (PD). METHODS: As part of a randomized controlled trial, patients were randomly assigned to 6 weeks of TT (n = 17, mean age 71.5 ± 1.5 years, disease duration 11.6 ± 1.6 years; 70% men) or TT + VR (n = 17, mean age 71.2 ± 1.7 years, disease duration 7.9 ± 1.4 years; 65% men). A previously validated fMRI imagery paradigm assessed changes in neural activation pretraining and post-training. Participants imagined themselves walking in 2 virtual scenes projected in the fMRI: (1) a clear path and (2) a path with virtual obstacles. Whole brain and region of interest analyses were performed. RESULTS: Brain activation patterns were similar between training arms before the interventions. After training, participants in the TT + VR arm had lower activation than the TT arm in Brodmann area 10 and the inferior frontal gyrus (cluster level familywise error-corrected [FWEcorr] p < 0.012), while the TT arm had lower activation than TT + VR in the cerebellum and middle temporal gyrus (cluster level FWEcorr p < 0.001). Changes in fall frequency and brain activation were correlated in the TT + VR arm. CONCLUSIONS: Exercise modifies brain activation patterns in patients with PD in a mode-specific manner. Motor-cognitive training decreased the reliance on frontal regions, which apparently resulted in improved function, perhaps reflecting increased brain efficiency.

Hypothalamus is a key brain region regulating several essential homeostatic functions, including the sleep-wake cycle. Alzheimer's disease (AD) pathology affects nuclei controlling sleep-wake rhythm sited in this brain area. Since only post-mortem studies documented the relationship between hypothalamic atrophy and sleep-wake cycle impairment, we investigated in AD patients the possible hypothalamic in vivo alteration using 2-deoxy-2-(18F) fluoro-D-glucose ([18F]FDG) positron emission tomography ([18F]FDG PET), and its correlations with sleep impairment and cerebrospinal-fluid (CSF) AD biomarkers (tau proteins and ß-amyloid42). We measured sleep by polysomnography, CSF AD biomarkers and orexin levels, and hypothalamic [18F]FDG PET uptake in a population of AD patients compared to age- and sex-matched controls. We documented the significant reduction of hypothalamic [18F]FDG PET uptake in AD patients (n = 18) compared to controls (n = 18) (p < 0.01). Moreover, we found the increase of CSF orexin levels coupled with the marked alteration of nocturnal sleep in AD patients than controls. We observed the significant association linking the reduction of both sleep efficiency and REM sleep to the reduction of hypothalamic [18F]FDG PET uptake in the AD group, which in turn negatively correlated with the total-tau/beta-amyloid42 ratio (index of more marked neurodegeneration). Moreover, controls but not AD patients showed [18F]FDG PET interconnections between hypothalamus and limbic system. We documented the in vivo dysfunction of hypothalamus in AD patients, which lost the physiological connections with limbic system and was correlated with both nocturnal sleep disruption and CSF AD biomarkers.

Alzheimer's disease (AD) is associated with the unprecedented aging tendency in our world population and has become a significant health issue. The use of Traditional Chinese Medicine to treat AD has been increasing in recent years. The objective of this meta-analysis is to evaluate the effectiveness of combining acupuncture with herbal medicine to treat AD. Randomized controlled trials (RCTs) of acupuncture plus herbals versus treatment with western drugs for AD were retrieved from 11 databases. The data were extracted by two authors; dichotomous data were expressed as odds ratio (ORs) and 95% confidence intervals (CIs), while continuous data were calculated by mean differences (MDs) with 95% CIs. Although the combined analysis of the score of Activity of Daily Life (ADL) scale MD was [Formula: see text]3.59 (95% CI [Formula: see text]7.18-0.01, [Formula: see text]), which indicates there was no statistically significant difference between the two treatments at reducing the ADL scale score, the pooled results of 12 trials indicated that acupuncture plus Chinese herbal medicine was better than western drugs at improving the effectiveness rate (OR 2.24, 95% CI 1.40-3.56), the combined evidence of 11 articles showed that acupuncture plus Chinese herbal medicine was more effective than western drugs at improving the scores for the Mini Mental State Examination (MMSE) scale (2.10, 95% CI 0.69-3.51, [Formula: see text]) and the traditional Chinese medicine symptom (MD 5.07, 95% CI 3.90-6.25, [Formula: see text]). From the current research results, acupuncture plus herbal medicine may have advantages over western drugs for treating AD. Nevertheless, well-designed RCTs with a larger sample size are required in the future.

To study the therapeutic effect of neuromuscular electrical stimulation and electromyographic biofeedback (EMG-biofeedback) therapy in improving swallowing function of Alzheimer's disease patients with dysphagia.A series of 103 Alzheimer's disease patients with dysphagia were divided into 2 groups, among which the control group (nâ=â50) received swallowing function training and the treatment group (nâ=â53) received neuromuscular electrical stimulation plus EMG-biofeedback therapy. The mini-mental state scale score was performed in all patients along the treatment period. Twelve weeks after the treatment, the swallowing function was assessed by the water swallow test. The nutritional status was evaluated by Mini Nutritional Assessment (MNA) as well as the levels of hemoglobin and serum albumin. The frequency and course of aspiration pneumonia were also recorded.No significant difference on mini-mental state scale score was noted between 2 groups. More improvement of swallowing function, better nutritional status, and less frequency and shorter course of aspiration pneumonia were presented in treatment group when compared with the control group.Neuromuscular electrical stimulation and EMG-biofeedback treatment can improve swallowing function in patients with Alzheimer's disease and significantly reduce the incidence of adverse outcomes. Thus, they should be promoted in clinical practice.

BACKGROUND: Non-verbal auditory impairment is increasingly recognised in the primary progressive aphasias (PPAs) but its relationship to speech processing and brain substrates has not been defined. Here we addressed these issues in patients representing the non-fluent variant (nfvPPA) and semantic variant (svPPA) syndromes of PPA. METHODS: We studied 19 patients with PPA in relation to 19 healthy older individuals. We manipulated three key auditory parameters-temporal regularity, phonemic spectral structure and prosodic predictability (an index of fundamental information content, or entropy)-in sequences of spoken syllables. The ability of participants to process these parameters was assessed using two-alternative, forced-choice tasks and neuroanatomical associations of task performance were assessed using voxel-based morphometry of patients' brain magnetic resonance images. RESULTS: Relative to healthy controls, both the nfvPPA and svPPA groups had impaired processing of phonemic spectral structure and signal predictability while the nfvPPA group additionally had impaired processing of temporal regularity in speech signals. Task performance correlated with standard disease severity and neurolinguistic measures. Across the patient cohort, performance on the temporal regularity task was associated with grey matter in the left supplementary motor area and right caudate, performance on the phoneme processing task was associated with grey matter in the left supramarginal gyrus, and performance on the prosodic predictability task was associated with grey matter in the right putamen. CONCLUSIONS: Our findings suggest that PPA syndromes may be underpinned by more generic deficits of auditory signal analysis, with a distributed cortico-subcortical neuraoanatomical substrate extending beyond the canonical language network. This has implications for syndrome classification and biomarker development.

OBJECTIVE: Disturbances of circadian rest-activity rhythms in demented patients often culminate in the clinical problem of evening and nighttime agitation. The aim of the current study was to test the impact of a dynamic lighting system on agitation and rest-activity cycles in patients with dementia. METHODS: From midwinter on, a ceiling mounted dynamic lighting system was installed in the common room of a nursing home and programmed to produce high illuminance with higher blue light proportions during the day and lower illuminance without blue light in the evening. Fifteen residents with dementia were regularly assessed with the Cohen Mansfield Agitation Index (CMAI) before and after the lighting intervention. Additionally rest-activity cycles were continuously monitored for 6 months by a wrist worn activity watch. Analysis of CMAI data was performed by using the Wilcoxon-Test for matched pairs (before vs. after the lighting installation). Rest-activity data was compared with t-tests for dependent samples. The dynamic lighting significantly reduced the CMAI sum-scores from 30.2±5.1 to 27.9±2.6 (mean ± SD; N = 12; p<0.05). Analysis of the CMAI subscores revealed that under the dynamic lighting mainly non-physically aggressive behaviors were reduced. RESULTS: Results from the rest-activity analysis did not show differences of circadian amplitude and other circadian variables before and after the lighting installation. The dynamic lighting in the living room significantly reduced agitated behavior in demented patients, indicating short-term benefits from higher daily light exposures. Whether such lighting also impacts long-term (circadian) rest-activity cycles needs to be further investigated.

Electro-acupuncture is a burgeoning treatment using the needle inserting into the body acupoints and the low-frequency pulse current being electrified by an electric acupuncture machine. This study was designed to evaluate the effects of preconditioning of electro-acupuncture on postoperative cognitive dysfunction in elderly.Ninety patients scheduled spine surgery were randomly assigned into 2 groups using a random number table: control group (group C) and electro-acupuncture group (group EA). In group EA, electro-acupuncture was applied on Baihui, Dazhui, and Zusanli acupoints 30âminutes before anesthesia. At 0âminute before treatment of electro-acupuncture, 1âhour after skin incision and surgery completed (T1-3), blood samples were taken for detection of interleukin (IL)-6, IL-10, and S100ß by enzyme-linked immunosorbent assay. The total dose of remifentanil and propofol during surgery were recorded. Mini-Mental State Examination was applied to evaluate the cognitive function of patients at 1 day before surgery and 7th and 30th day after surgery.The results showed that compared with group C, score of MMSE increased after surgery, the serum concentration of IL-6, IL-10, and S100ß decreased at 1âhour after skin incision, and surgery completed in group EA. Moreover, the total dose of remifentanil and propofol reduced during surgery in group EA.The present study suggests that preconditioning of electro-acupuncture could improve the postoperative cognitive function, and the reduction of inflammatory reaction and brain injury may be involved in the mechanism.

Early maladaptive schemas (EMSs) are maladaptive beliefs about oneself and ones relationships with others that originate from adverse childhood experiences and lead to psychological distress when activated. Schema therapy (ST) was developed to treat EMSs and maladaptive coping responses to the triggering of EMSs. Mindfulness-based interventions are increasingly used in ST. The purpose of the present study was to explore the relationships between EMSs, mindfulness, self-compassion, and psychological distress. The Young Schema Questionnaire (YSQ-S3), the Five Facet Mindfulness Questionnaire (FFMQ-SF), the Self-Compassion Scale (SCS-SF), and the Brief Symptom Inventory (BSI) were administered to 212 undergraduate psychology students (mean age= 21.8 years, SD= 4.4). The results showed negative associations between EMSs and mindfulness and self-compassion. Mindfulness and self-compassion mediated, but did not moderate, the associations between EMSs and psychological distress. It is concluded that low mindfulness and low self-compassion are mechanisms through which EMSs exert their effect on psychological distress. These findings support the use of techniques aimed at enhancing mindfulness and self-compassion in the treatment of EMSs (AU)

The Rey Auditory Verbal Learning Test (RAVLT) is widely used in clinical practice to evaluate verbal episodic memory. While there is evidence that RAVLT performance can be influenced by executive dysfunction, the way executive disorders affect the serial position curve (SPC) has not been yet explored. To this aim, we analysed immediate and delayed recall performances of 13 non-demented amyotrophic lateral sclerosis (ALS) patients with a specific mild executive dysfunction (ALSci) and compared their performances to those of 48 healthy controls (HC) and 13 cognitively normal patients with ALS. Moreover, to control for the impact of a severe dysexecutive syndrome and a genuine episodic memory deficit on the SPC, we enrolled 15 patients with a diagnosis of behavioural variant of frontotemporal dementia (bvFTD) and 18 patients with probable Alzheimer's disease (AD). Results documented that, compared to cognitively normal subjects, ALSci patients had a selective mid-list impairment for immediate recall scores. The bvFTD group obtained low performances with a selectively increased forgetting rate for terminal items, whereas the AD group showed a disproportionately large memory loss on the primary and middle part of the SPC for immediate recall scores and were severely impaired in the delayed recall trial. These results suggested that subtle executive dysfunctions might influence the recall of mid-list items, possibly reflecting deficiency in control strategies at retrieval of word lists, whereas severer dysexecutive syndrome might also affect the recall of terminal items possibly due to attention deficit or retroactive interference.

OBJECTIVE: l-theanine, an amino acid uniquely contained in green tea (Camellia sinensis), has been suggested to have various psychotropic effects. This study aimed to examine whether l-theanine is effective for patients with major depressive disorder (MDD) in an open-label clinical trial. METHODS: Subjects were 20 patients with MDD (four males; mean age: 41.0±14.1 years, 16 females; 42.9±12.0 years). l-theanine (250 mg/day) was added to the current medication of each participant for 8 weeks. Symptoms and cognitive functions were assessed at baseline, 4, and 8 weeks after l-theanine administration by the 21-item version of the Hamilton Depression Rating Scale (HAMD-21), State-Trait Anxiety Inventory (STAI), Pittsburgh Sleep Quality Index (PSQI), Stroop test, and Brief Assessment of Cognition in Schizophrenia (BACS). RESULTS: HAMD-21 score was reduced after l-theanine administration (p=0.007). This reduction was observed in unremitted patients (HAMD-21>7; p=0.004) at baseline. Anxiety-trait scores decreased after l-theanine administration (p=0.012) in the STAI test. PSQI scores also decreased after l-theanine administration (p=0.030) in the unremitted patients at baseline. Regarding cognitive functions, response latency (p=0.001) and error rate (p=0.036) decreased in the Stroop test, and verbal memory (p=0.005) and executive function (p=0.016) were enhanced in the BACS test after l-theanine administration. CONCLUSION: Our study suggests that chronic (8-week) l-theanine administration is safe and has multiple beneficial effects on depressive symptoms, anxiety, sleep disturbance and cognitive impairments in patients with MDD. However, since this is an open-label study, placebo-controlled studies are required to consolidate the effects.
