Anhedonia in bipolar depression treated with ketamine.

BACKGROUND: Bipolar depression is the major cause of morbidity in patients with bipolar disorder. It affects psychosocial functioning and markedly impairs occupational productivity. Anhedonia is one of the most debilitating symptoms of depression contributing to treatment resistance. It correlates with suicidality, low quality of life, social withdrawal, and poor treatment response. Currently, there is no approved treatment specifically targeting anhedonia. Emerging evidence suggests that ketamine possesses anti-anhedonic properties in individuals with depression. OBJECTIVES: The aim of this naturalistic open-label study was to investigate the effect of add-on ketamine treatment on anhedonia in treatment resistant bipolar depression. METHODS: Our main interest was the change in patient-reported (Snaith-Hamilton Pleasure Scale) and rater-based anhedonia measure (Montgomery-Åsberg Depression Rating Scale-anhedonia subscale). The secondary aim was to analyze the score change in three Inventory of Depressive Symptomatology-Self Report (IDS-SR) domains: mood/cognition, anxiety/somatic, and sleep. Patients underwent assessments at several time points, including baseline, after the third, fifth, and seventh ketamine infusions. Additionally, a follow-up assessment was conducted 1 week following the final ketamine administration. RESULTS: We found improvement in anhedonia symptoms according to both patient-reported and rater-based measures. The improvement in IDS-SR domains was most prominent in anxiety/somatic factor and mood/cognition factor, improvement in sleep factor was not observed. No serious adverse events occurred. CONCLUSION: Add-on ketamine seems to be a good choice for the treatment of anhedonia in treatment resistant bipolar depression. It also showed a good effect in reducing symptoms of anxiety in this group of patients. Considering unmet needs and the detrimental effect of anhedonia and anxiety, more studies are needed on ketamine treatment in resistant bipolar depression.

Bipolar spectrum in prostate cancer patients and its role in stress related symptoms.

BACKGROUND: Studies show significant co-occurrence of bipolar disorder and prostate cancer, as well as the presence of shared genes associated with both diseases. Our aim was to evaluate whether prostate cancer patients present bipolar spectrum symptoms and to establish their possible associations with stress related symptoms during diagnosis and the course of the cancer therapy. METHODS: 200 participants were enrolled to this study: 100 prostate cancer patients and 100 healthy males. Bipolar spectrum symptoms were measured with the use of Mood Disorder Questionnaire and Hypomania Checklist-32 (HCL-32). Stress related symptoms were rated with The Impact of Events Scale-Revised (IES-R), Perceived Stress Scale-10 (PSS-10) and Generalised Self-Efficacy Scale (GSES). RESULTS: In comparison to healthy controls group, prostate cancer patients have shown higher HCL-32 scores. Mood Disorder Questionnaire measures were associated with more severe stress related to prostate cancer diagnosis and treatment reflected by higher scores of IES-R and its subscales (Avoidance, Intrusions and Hyperarousal). Mood Disorder Questionnaire, HCL-32, PSS-10, IES-R and GSES measures were not associated with clinical characteristics of prostate cancer severity. LIMITATIONS: Cross-sectional study model precluded identification of causal relationship among variables. Bipolar spectrum symptoms and stress related measures were based on auto-questionnaires. CONCLUSIONS: To our best knowledge, this is the first study evaluating bipolar spectrum symptoms in prostate cancer patients. We have shown that this clinical group presents increased bipolarity traits compared to healthy individuals. Moreover, bipolar spectrum symptoms were associated with more severe stress related to the prostate cancer diagnosis and its treatment, reflected in avoidance, hyperarousal, and intrusions.

Predictors of Satisfaction with Care in Patients Suffering from Schizophrenia Treated Under Community Mental Health Teams.

The aim of this study was to assess satisfaction with care and to identify the predictors of this variable among sociodemographic, clinical and social data in a group of patients suffering from schizophrenia under treatment in community mental health teams. The study included 90 patients with a diagnosis of schizophrenia under the care of community mental health teams. Positive and Negative SyndromeScale, Verona Service Satisfaction Scale, Disability Assessment Schedule, Social Network Index and a loneliness scale (UCLA Loneliness Scale)were used in the study. Prognostic factors for higher satisfaction with care in the multivariate model involved: level of disability (Beta = -0.46, p < 0.001), duration of treatment under a CMHT (Beta = 0.36, p < 0.001), age (Beta = -0.37,p < 0.001), and education (Beta = -0.30, p = 0.002). The model explained 43% of the variance in the dependent variable. 1.Satisfaction with care in a CMHT was high. 2. Higher patient satisfaction could be predicted based on a lower level of disability, longer duration of treatment under a CMHT, lower age and lower education.

Cognitive Biases and Socio-Occupational Functioning Mediate the Relationship between Executive Functions and the Severity of Psychopathology among Young Adults with Psychotic-like Experiences: 1-Year Follow-Up Study.

The aim of this study was to investigate whether Trail Making Test (TMT) performance is associated with the severity of psychopathological symptoms related to psychosis among young adults with elevated level of psychotic-like experiences (PLEs), and whether this relationship is mediated by cognitive biases and socio-occupational functioning. A total of 187 subjects from a larger population of 6722 young adults participated in this 1-year follow-up study. The inclusion criteria were an elevated level of PLEs (the highest score of the Prodromal Questionnaire) and a lack of schizophrenia diagnosis. Eventually, 134 subjects (71.6%) completed the TMT, as well as the DACOBS scale (cognitive biases), at baseline and were examined twice using the CAARMS (psychopathology) and SOFAS (socio-occupational functioning) scales. In the first (I) and second (II) measurements, the calculated effects indicate indirect-only mediations, which explained 35 and 38% of the variance of the CAARMS. The TMT B execution time was positively associated with the DACOBS scale (ß = 0.19, p = 0.028), which was negatively related to the SOFAS I (ß = -0.37, p < 0.001) and SOFAS II (ß = -0.20, p = 0.016) measurements. A lower score on the SOFAS I predicted a higher score on the CAARMS I (ß = -0.50, p < 0.001), and a lower SOFAS II predicted a higher score on the CAARMS II (ß = -0.61, p < 0.001). Subtle EF dysfunctions may, over time, translate into a greater severity of symptoms related to psychosis in people with elevated PLEs, and this is mediated by a deterioration of their metacognition and socio-occupational functioning.

Satisfaction with care in patients with schizophrenia treated in a pilot-program model and traditional care. / Satysfakcja z opieki u pacjentów chorujacych na schizofrenie w modelu pilotazowym i opiece tradycyjnej.

OBJECTIVES: The purpose of this study was to compare satisfaction with care in patients with schizophrenia in two CMHT models: traditional and pilot program group with concurrent assessment of symptom severity and social functioning. METHODS: Ninety patients with schizophrenia treated in Community Mental Health Teams were included in the study, 60 in the traditional model and 30 in the pilot-program model.A demographic data questionnaire, the Positive and Negative Syndrome Scale (PANSS), the Verona Service Satisfaction Scale (VSSS-54), the Disability Assessment Schedule (WHODAS), the Social Network Index (SNI),and a scale measuring loneliness (UCLA Loneliness Scale) were used. RESULTS: The pilot-program group was characterized by significantly lower age of subjects (p=0.048), less psychiatric medication use (p=0.027), higher total(p<0.001) and positive (p<0.001) symptom severity in PANSS, smaller social network (p=0.003), less role activity in social network (p<0.001), higher level of loneliness (p=0.001) and higher level of disability (p<0.001). The pilot-program group had significantly higher satisfaction with involvement of families in the therapeutic process(p = 0.024). CONCLUSIONS: In the pilot-program group, younger, more severely ill patients with higher severity of symptoms and worse social functioning were included in the treatment with no differences in the number of hospitalizations between the groups. It can be concluded that CMHT in the pilot-program Mental Health Centers (MHCs) protects this group of patients from hospitalization. There was also higher satisfaction with family involvement in the therapeutic process in the pilot-program group. A valuable continuation of the study would be to evaluate the treatment outcomes in all CMHTs operating under the pilot-program MHCs.

Burden of caregivers of people suffering from schizophrenia versus symptom severity, social functioning and treatment satisfaction of patients treated by a CMHT. / Obciazenie opiekunów osób chorujacych na schizofrenie a nasilenie objawów, funkcjonowanie spoleczne i satysfakcja z leczenia pacjentów leczonych w ZLS.

OBJECTIVES: This study aims to assess the caregivers' burden in schizophrenia amongst patients treated by Community Mental Health Teams (CMHTs) and its relation to patients' demographic, clinical and social characteristics, with emphasis on their satisfaction with care, and to evaluate the correlation of selected characteristics of caregivers with the level of their burden. METHODS: A total of 65 patient-caregiver dyads remaining in home treatment were included. Caregivers were assessed with demographic questionnaires, and the Caregiver Burden Inventory (CBI). The patients were assessed with the Positive and Negative Syndrome Scale (PANSS), the Verona Service Satisfaction Scale (VSSS-54), the Disability Assessment Schedule (WHODAS 2.0), the Social Network Index (SNI) and with the UCLA Loneliness Scale. Data were analysed using multiple linear regression. RESULTS: Increased caregiver burden was associated with: greater symptom severity in patients, lower satisfaction with staff professionalism, and a high level of emotional expressiveness in relationships. The regression model explaining 57% of the variance in the caregivers' emotional burden consisted of four factors: the patient's positive syndrome intensity, patient's remaining in an emotional relationship, gender i.e. higher burden amongst female caregivers of male patients, and smaller social network. CONCLUSIONS: The caregivers' burden severity is related to patients' sociodemographic, clinical and social characteristics and their satisfaction with treatment. The emotional burden of caregivers is impacted by: greater symptom severity, especially the positive syndrome, lower patient satisfaction with staff professionalism, and a high expression of emotions in family relationships. The patient's and caregiver's gender and education level, the patient's degree of disability, them being in a relationship and social support network size are also significant.

Graph Analysis of Verbal Fluency Tests in Schizophrenia and Bipolar Disorder.

Verbal Fluency Tests (VFT) are one of the most common neuropsychological tasks used in bipolar disorder (BD) and schizophrenia (SZ) research. Recently, a new VFT analysis method based on graph theory was developed. Interpreting spoken words as nodes and every temporal connection between consecutive words as edges, researchers created graph structures, allowing the extraction of more data from participants' speech, called Speech Graph Attributes (SGA). The aim of our study was to compare speech graphs, derived from Phonemic and Semantic VFT, between SZ, BD, and healthy controls (HC). Twenty-nine SZ patients, twenty-nine BD patients, and twenty-nine HC performed Semantic and Phonemic VFT. Standard measures (SM) and 13 SGA were analyzed. SZ patients' Semantic VFT graphs showed lower total word count and correct responses. Their graphs presented less nodes and edges, higher density, smaller diameter, average shortest path (ASP), and largest strongly connected component than the HC group. SM did not differentiate BD and HC groups, and patients' Semantic VFT graphs presented smaller diameter and ASP than HC. None of the parameters differentiated BD and SZ patients. Our results encourage the use of speech graph analysis, as it reveals verbal fluency alterations that remained unnoticed in the routine comparisons of groups with the use SM.

Premorbid social relationships and the course of schizophrenia in a 20-year follow-up study. / Relacje spoleczne przed wybuchem choroby a przebieg schizofrenii przez okres 20 lat.

OBJECTIVES: An important dimension indicating a growing risk of psychosis outbreak and its subsequent unfavorable course is deteriorating social functioning, especially the lack of sufficient social relationships. The aim of the study was to evaluate the association of the quality of social contacts and the scope of support system before the onset of the illness with treatment outcomes in clinical and social dimension in various time intervals of the 20-year illness course. METHODS: During the first hospitalization, an 80-person group living in Krakow and suffering from schizophrenia was selected, diagnosed according to DSM-IV-TR criteria and examined six times: at admission and discharge during first hospitalization, after 3, 7, 12 and 20 years. The analysis involved 55 persons (69% of the group included to the study) who went through all the examinations over a period of 20 years. Two-factor analysis of variance was used with one grouping factor (social contacts) and one repeated measures factor (follow-ups) for the results of GAF, BPRS, DSM-III Axis V and a series of simple linear regressions for the associations between these outcome indicators and the Surtees' Index of Social Support. RESULTS: Satisfactory, positive contacts before the outbreak of the illness translated, especially after 20 years, into better general and social functioning and fewer symptoms, especially negative ones. Awider social support before the outbreak was associated with better general and social functioning of patients and lesser severity of general, positiveand negative symptoms; however, in this last case the effect disappeared after 20 years. CONCLUSIONS: The quality and scope of social contacts before the outbreak of the illness, especially satisfactory relationship in non-familial milieu, are an important prognostic factor of amany-year beneficial clinical and social course of psychoses from the schizophrenia group.
