Abstract Background This feasibility study evaluated adherence and effectiveness to a digital multimodal intervention (cognitive and physical training) for cancer-related cognitive impairment (CRCI) in patients with breast cancer. Methods Breast cancer patients undergoing radiotherapy and with significant cognitive complaints impacting quality of life participated in a 12-week intervention, combining non-simultaneous 20-min cognitive and 30-min physical sessions, twice weekly. Assessments included perceived cognitive impairment (PCI), objective cognition, fatigue, anxiety/depression, sleep and satisfaction. High level of adherence was defined as completing 9/12 weeks of the program. A week was complete when at least 70% of each of the planned sessions was completed. Physical activity intensity was defined by max age-related heart rate. Results Among 419 radiotherapy-treated patients with breast cancer, 170 had cognitive complaints (41%), 83 were eligible (49%), 29 were not included (35%) due to organizational issue and 20 among eligible contacted patients agreed to participate (37%). The majority of participants (48.3 ± 8 years of age) received chemotherapy (18/20) and 17 had I-II cancer stage. Eleven of twenty participants were highly adherent (higher adherence in physical (95%) than cognitive training (55%)). All expressed satisfaction. Post-intervention, overall objective cognition (p = 0.016), PCI (p = 0.004), fatigue (p = 0.011), and depression (p = 0.049) significantly improved. Post-intervention, high adherence was associated with significant improvements in PCI (p = 0.01) and fatigue (p = 0.03). High-intensity physical training was associated with significant improvements in PCI (p < 0.05), fatigue (p = 0.011) and depression (p = 0.037). Conclusions This intervention showed to be feasible and potentially efficient for the management of CRCI in patients with breast cancer. Trial registration NCT04213365, 27/12/2019.

Background and objective: Multiple system atrophy is a rare and fatal neurodegenerative disorder, characterized by autonomic dysfunction in association with either parkinsonism or cerebellar signs. The pathologic hallmark is the presence of alpha-synuclein aggregates in oligodendrocytes, forming glial cytoplasmic inclusions. Clinically, it may be difficult to distinguish form other parkinsonisms or ataxias, particularly in the early stages of the disease. In this case series we aim to describe in detail the features of MSA patients. Material and methods: Unified MSA Rating Scale (UMSARS) score, structural and functional imaging and cardiovascular autonomic testing, are summarized since early stages of the disease. Results: UMSARS proved to be useful to perform a follow-up being longitudinal examination essential to stratify risk of poor outcome. Neuropathological diagnosis showed an overlap between parkinsonian and cerebellar subtypes, with some peculiarities that could help to distinguish from other subtypes. Conclusion: A better description of MSA features with standardized test confirmed by means of neuropathological studies could help to increase sensitivity. Resumen: Antecedentes y objetivo: La atrofia multisistémica es un trastorno neurodegenerativo raro y letal que se caracteriza por una disfunción autonómica en asociación con parkinsonismo o signos cerebelosos. La marca anatomopatológica es la presencia de agregados de α-sinucleína en los oligodendrocitos, que forman inclusiones citoplasmáticas gliales. Desde un punto de vista clínico, puede ser difícil de distinguir de otros parkinsonismos o ataxias, particularmente en las primeras etapas de la enfermedad. En esta serie de casos, nuestro objetivo es describir en detalle las características de los pacientes con atrofia multisistémica. Material y métodos: Se resumen los datos objetidos de la puntuación de la Escala de calificación unificada de la atrofia multisistémica (UMSARS), imágenes estructurales y funcionales y las pruebas autonómicas cardiovasculares realizadas desde las primeras etapas de la enfermedad. Resultados: La escala UMSAR demostró ser útil para hacer un seguimiento: el examen longitudinal esencial fue para estratificar el riesgo de peor evolución. El diagnóstico neuropatológico mostró un solapamiento entre los subtipos parkinsoniano y cerebeloso, con algunas peculiaridades que podrían ayudar a distinguir los subtipos. Conclusión: Una mejor descripción de las características de la atrofia multisistémica en casos confirmados mediante neuropatología podría ayudar a aumentar la sensibilidad del diagnóstico.

Developing optogenetic methods for research in non-human primates (NHP) is important for translational neuroscience and for delineating brain function with unprecedented specificity. Here we assess, in macaque monkeys, the selectivity by which optogenetic stimulation of the primary visual cortex (V1) drives the local laminar and widespread cortical connectivity related to visual perception. Towards this end, we transfected neurons with light-sensitive channelrhodopsin in dorsal V1. fMRI revealed that optogenetic stimulation of V1 using blue light at 40 Hz increased functional activity in the visual association cortex, including areas V2/V3, V4, motion-sensitive area MT and frontal eye fields, although nonspecific heating and eye movement contributions to this effect could not be ruled out. Neurophysiology and immunohistochemistry analyses confirmed optogenetic modulation of spiking activity and opsin expression with the strongest expression in layer 4-B in V1. Stimulating this pathway during a perceptual decision task effectively elicited a phosphene percept in the receptive field of the stimulated neurons in one monkey. Taken together, our findings demonstrate the great potential of optogenetic methods to drive the large-scale cortical circuits of the primate brain with high functional and spatial specificity.

ObjectiveThis study aimed to analyze the cerebrospinal fluid (CSF) parameters affecting the outcomes of patients with tuberculous meningitis (TBM).MethodsThis is a multi-center, retrospective, cohort study involving 81 patients who were diagnosed with TBM and treated in Haihe Clinical College of Tianjin Medical University, Tianjin Medical University General Hospital, and General Hospital of Air Force PLA from January 2016 to December 2019. Baseline data, Glasgow Coma Scale (GCS) score, and clinical presentations of all patients were collected at admission. CSF samples were collected at 48 h, 1, 2, and 3 weeks after admission. CSF lactate, adenosine deaminase, chloride, protein, glucose levels and intracranial pressure were measured. After a follow-up of 16.14 ± 3.03 months, all patients were assessed using the modified Rankin Scale (mRS) and divided into good (mRS scores of 0–2 points) and poor outcome groups (mRS scores of 3–6 points). The differences in patients' baseline data, GCS score, clinical presentations, and levels of CSF parameters detected at 48 h, 1, 2, and 3 weeks after admission between two groups were compared. Statistically significant variables were added to the binary logistic regression model to identify the factors impacting the outcomes of patients with TBM. Receiver operating characteristic (ROC) curve was used to assess the predictive ability of the model.ResultsThe CSF lactate level exhibited a decreasing trend within 3 weeks of admission in the two groups. For the within-group comparison, statistically significant differences in the lactate level was found in both groups between four different time points. A binary logistic regression model revealed that CSF lactate level at 48 h after admission, age, and GSC score on admission were independently associated with the outcomes of patients with TBM. ROC curve analysis showed that the area under the ROC curve (AUC) was 0.786 for the CSF lactate level (48 h), 0.814 for GCS score, and 0.764 for age.ConclusionHigh CSF lactate level at 48 h after admission is one of the important factors for poor outcomes in patients with TBM.

ObjectiveThis randomized single-blind controlled trial tested the hypothesis that a prototype digital therapeutic developed to provide goal-based counseling with personalized passive and active game-based sound therapy would provide superior tinnitus outcomes, and similar usability, to a popular passive sound therapy app over a 12 week trial period.MethodsThe digital therapeutic consisted of an app for iPhone or Android smartphone, Bluetooth bone conduction headphones, neck pillow speaker, and a cloud-based clinician dashboard to enable messaging and app personalization. The control app was a popular self-help passive sound therapy app called White Noise Lite (WN). The primary outcome measure was clinically meaningful change in Tinnitus Functional Index (TFI) between baseline and 12 weeks of therapy. Secondary tinnitus measures were the TFI total score and subscales across sessions, rating scales and the Client Oriented Scale of Improvement in Tinnitus (COSIT). Usability of the US and WN interventions were assessed using the System Usability Scale (SUS) and the mHealth App Usability Questionnaire (MAUQ). Ninety-eight participants who were smartphone app users and had chronic moderate-severe tinnitus (&gt;6 months, TFI score &gt; 40) were enrolled and were randomly allocated to one of the intervention groups. Thirty-one participants in the USL group and 30 in the WN group completed 12 weeks of trial.ResultsMean changes in TFI for the USL group at 6 (16.36, SD 17.96) and 12 weeks (17.83 points, SD 19.87) were clinically meaningful (&gt;13 points reduction), the mean change in WN scores were not clinically meaningful (6 weeks 10.77, SD 18.53; 12 weeks 10.12 points, SD 21.36). A statistically higher proportion of USL participants achieved meaningful TFI change at 6 weeks (55%) and 12 weeks (65%) than the WN group at 6 weeks (33%) and 12 weeks (43%). Mean TFI, rating and COSIT scores favored the US group but were not statistically different from WN. Usability measures were similar for both groups.ConclusionsThe USL group demonstrated a higher proportion of responders than the WN group. The usability of the USL therapeutic was similar to the established WN app. The digital polytherapeutic demonstrated significant benefit for tinnitus reduction supporting further development.

Background: Childhood adverse experiences may come to bear particularly during adolescence, when neural reward systems are developing rapidly and psychopathology spikes. Despite prior work differentiating threat- (abuse) vs. deprivation- (neglect) related adversity, no research has yet identified their relative nor interactive contributions to reward neural substrates during adolescence. In the present study, we leveraged a diverse sample of adolescents with different childhood adversity profiles to examine neural responses to reward in relation to varying degrees of abuse vs. neglect. Methods: Adolescents (N = 45; 23 females; mean age = 14.9 years, SD = 1.9) completed a child-friendly monetary incentive delay task during fMRI acquisition. The self-report Childhood Trauma Questionnaire assessed childhood abuse and neglect. Whole brain ANCOVA analyses evaluated reward anticipation (reward vs. no reward expected) and feedback (hitting vs. missing the target with a reward vs. no reward) in relation to abuse and neglect dimensions. Results: Whole-brain analyses revealed that abuse, adjusted for neglect, is associated with greater differences between task conditions (reward vs. no reward, hit vs. miss) in regions associated with threat/emotion regulation (prefrontal and temporal cortices, as well as posterior regions including fusiform and posterior cingulate/precuneus). Additionally, level of neglect modulated neural response associated with abuse in prefrontal and temporoparietal regions, such that youths with high levels of both abuse and neglect showed qualitatively different, more exaggerated neural patterns compared to youths with elevated adversity in only one dimension. Conclusions: Our findings suggest that early experiences of abuse and neglect have a long developmental reach resulting in reward-related neural alterations in adolescence. Moreover, our results bolster theoretical conceptualizations of adversity along threat and deprivation dimensions and provide evidence that “adding up” adverse life events may not be sufficient to capture the qualitatively different neural profiles produced by differing combinations of types of adversity, which may in turn necessitate different treatment approaches.

Introduction Depressive disorders are common for cardiac patients; however, a surgical intervention enhances their distress. How typical is suicidal ideation for cardiac surgery patients and with what clinical and psychological signs does it correlate? Objectives To estimate the frequency of suicidal ideation and correlations between suicidal ideation, clinical and psychological manifestations in cardiac surgery patients. Methods We examined 60 cardiac surgery patients, aged 25 – 65, prior to their operation. The Pierson correlation between manifestation of suicidal ideation, clinical and psychological signs was calculated with p<0.05. Results We revealed suicidal ideation in 3.33% of cardiac surgery patients. Its intensity credibly correlated with the frequency of taking alcohol (r=.32), as well as with manifestation of dysorexia (r=.59), dissatisfaction with life (r=.53), general level of depression (r=.49), sleeping disorders (r=.44), sense of guilt (r=.43), asthenia (r=.31), self-abhorrence (r=.29), and irritability(r=.29). A higher level of suicidal ideation correlated with a lower index of Positive-Past in their personal time perspective (r=-.27), which revealed itself in a patient having lack of positive impressions and recollections of their past life, which reduced a person’s adaptability in the present. Conclusions The frequency of suicidal ideation in preoperative cardiac surgery patients is not high. Nevertheless, we should bear in mind that high suicidal risk is characteristic for patients with not only depression, but also alcohol problems, as well as for those who have manifestations of negative attitude to their past. Disclosure No significant relationships.

Dissociative identity disorder’s origin is often traced back to early traumatization. This disorder is difficult to diagnose within a short appointment, and the patient may appear psychotic. We describe a patient case in which a threat of suicidal behaviour led to a further assessment in adolescent psychiatric services. A diagnosis of psychotic depression with traumatic experiences was suspected initially. The functioning of the patient remained relatively intact without treatment of psychosis. A thorough differential diagnostic study was performed due to unusual symptom presentation. The symptoms appearing psychotic were driven by communication between distinct personality states and by concerning memory gaps. Consequently, a diagnosis of dissociative identity disorder was made. The primary treatment recommendation for dissociative disorders that cause unexpected memory gaps or amnesia by expert consensus is psychotherapy. Amnesia can be frightening, and internal dialogue is difficult to explain to others. The goal of psychotherapeutic treatment is to integrate the distinct personality states or modes, to restore continuity in sense of self without memory gaps and to maintain functioning.

Background: Non-motor symptoms in PD usually arise at very early stage and vary during the whole disease progression. Deep brain stimulation (DBS) is considered as a highly efficient treatment option for PD's motor function. However, the effect of DBS on NMS, especially hyposmia, has not been fully understood and the deep connection between different NMS such as hyposmia and constipation is still unknown.Objective: The objective of this study was to evaluate the therapeutic effect of DBS on hyposmia in PD patients with or without constipation and find potential factors which might influence the efficacy.Methods: A retrospective analysis of 65 PD patients accepted STN-DBS operation in Qilu Hospital during 2019–2020 were conducted to evaluate the exact therapeutic effect of DBS on hyposmia in PD. Sub-group analyses about the relationship between hyposmia and constipation were carried out. Analysis of flora in nasal mucosa was also conducted to evaluate the abundance and variety in different PD groups.Results: Our study showed that DBS had clearly improved olfactory function in Parkinson patients (P = 0.012) and subgroup analysis found that PD patients with constipation have lower olfactory function scores (25.27 ± 3.44 vs. 33.90 ± 6.633, p = 0.014) and worse improvement after DBS operation (ΔTDI 12.11 ± 3.2 vs. 8.78 ± 2.91, p = 0.0072). Analysis of flora indicated the obvious discrepancy on olfactory function scores and degree of improvement might be related to the abundance and dysbiosis of microbiota.Conclusion: In summary, this article presents a study on PD with hyposmia and constipation after DBS operation, explored the relationship between different NMS and offer a potential explanation on why PD patients with constipation usually have worse olfactory function for the less abundance and variety of microbiota.

Alcohol drinking may be associated with an increased risk of various metabolic diseases. Rat lines selectively bred for alcohol preference and alcohol avoidance constitute an interesting model to study inherited factors related to alcohol drinking and metabolic disorders. The aim of the present study was to compare the levels of selected laboratory biomarkers of metabolic disorders in blood samples from naïve offspring of Warsaw alcohol high-preferring (WHP), Warsaw alcohol low-preferring (WLP), and wild Wistar rats. Blood samples were collected from 3-month old (300–350 g) alcohol-naïve, male offspring of WHP (n = 8) and WLP rats (n = 8), as well as alcohol-naïve, male, wild Wistar rats. Markers of metabolic, hepatic, and pancreatic disorders were analysed (levels of homocysteine, glucose, total cholesterol, triglycerides and γ-glutamyl transferase (GGT), aspartate (AST), alanine aminotransferase (ALT), and amylase serum activities). Alcohol-naïve offspring of WHP, WLP, and wild Wistar rats differed significantly in the levels of triglycerides, total cholesterol, homocysteine, as well as in the activity of GGT, ALT, AST, and amylase enzymes. Most markers in the alcohol-naïve offspring of WHP rats were altered even thought they were never exposed to alcohol pre- or postnatally. This may suggest that parental alcohol abuse can have a detrimental influence on offspring vulnerability to metabolic disorders.

Abstract Background There is a lack of high quality population-based studies from low- and middle-income countries examining the relative economic status of households with and without a member with a mental health problem. The aim of the study was to explore the socio-economic status of households with a person with severe mental disorder (SMD; psychosis or bipolar disorder) or depression compared to households without an affected person. Methods A population-based, comparative, cross-sectional household survey was conducted in Sodo district, south Ethiopia, between January and November 2015. Two samples were recruited, each with its own comparison group. Sample (1): households of 290 community-ascertained persons with a clinician-confirmed diagnosis of SMD and a comparison group of 289 households without a person with SMD. Sample (2): households of 128 people who attended the primary health care centre and who were identified by primary care staff as having a probable diagnosis of depressive disorder; and comparison households of 129 patients who attended for other reasons and who did not receive a diagnosis of depression. Household socioeconomic status (household income, consumption and asset-based wealth) was assessed using a contextualized version of theWorld Health Organization (WHO) Study on global Ageing and adult health (SAGE) questionnaire. Each disorder group (SMD and depression) was further divided into higher and lower disability groups on the basis of median score on the WHO Disability Assessment Schedule. Results Households of a person with SMD who had higher disability were more likely to have a poorer living standard (no toilet facility; p < 0.001). Having a reliable source of regular income was significantly lower in households of a person with SMD (p = 0.008) or depression (p = 0.046) with higher disability than the comparison group. Households of persons with SMD with higher disability earned less (p = 0.005) and owned significantly fewer assets (p < 0.001) than households without SMD. Households including persons with depression who had higher disability had lower income (p = 0.042) and reduced consumption (p = 0.048). Conclusions Households with a member who had either SMD or depression were socioeconomically disadvantaged compared to the general population. Moreover, higher disability was associated with worse socio-economic disadvantage. Prospective studies are needed to determine the direction of association. This study indicates a need to consider households of people with SMD or depression as a vulnerable group requiring economic support alongside access to evidence-based mental healthcare.

Group-based child-centered cognitive behavioral therapy (CBT) for children with aggressive behavior has been found to significantly reduce child behavior problems. Nevertheless, most children suffer from residual symptoms at the end of treatment. Therefore, individualized interventions that treat the specific problem-maintaining factors and that use digital support may enhance treatment effects. However, enhanced computer-facilitated interventions have not been examined in clinical samples. Therefore, we tested the efficacy of an individualized computer-facilitated social skills training for children with clinically referred aggressive behavior problems. Fifty children aged 6–12 years with peer-related aggressive behavior problems were included in a within-subject design with two phases (waiting, treatment). The course of the outcome measures during an 8-week waiting phase was compared with that in the subsequent treatment phase (16 weekly child sessions and 2 parent psychoeducation contacts at the beginning of the treatment) using multilevel modeling. The primary outcome was peer-related aggressive behavior rated by parents. Further outcome measures included parent ratings and patient self-reports of aggressive and prosocial behavior. No significant changes occurred for any of the outcome variables during the waiting phase. During treatment, most parent-rated outcome measures (including the primary outcome measure) showed a significant decrease, which was stronger than changes in the waiting phase. Most self-rated outcome measures also showed significant decreases during treatment, but a stronger decrease than in the waiting phase was only found for peer-related aggressive behavior. The computer-facilitated social skills training appears to be an effective CBT intervention for children with peer-related aggressive behavior.
