RESUMEN
AIM: Basic self disturbance is a putative core vulnerability marker of schizophrenia spectrum disorders. The primary aims of the Self, Neuroscience and Psychosis (SNAP) study are to: (1) empirically test a previously described neurophenomenological self-disturbance model of psychosis by examining the relationship between specific clinical, neurocognitive, and neurophysiological variables in UHR patients, and (2) develop a prediction model using these neurophenomenological disturbances for persistence or deterioration of UHR symptoms at 12-month follow-up. METHODS: SNAP is a longitudinal observational study. Participants include 400 UHR individuals, 100 clinical controls with no attenuated psychotic symptoms, and 50 healthy controls. All participants complete baseline clinical and neurocognitive assessments and electroencephalography. The UHR sample are followed up for a total of 24 months, with clinical assessment completed every 6 months. RESULTS: This paper presents the protocol of the SNAP study, including background rationale, aims and hypotheses, design, and assessment procedures. CONCLUSIONS: The SNAP study will test whether neurophenomenological disturbances associated with basic self-disturbance predict persistence or intensification of UHR symptomatology over a 2-year follow up period, and how specific these disturbances are to a clinical population with attenuated psychotic symptoms. This may ultimately inform clinical care and pathoaetiological models of psychosis.

INTRODUCTION: The distinction between the schizophrenia spectrum and other types of disorders may be clinically relevant in terms of its predictive validity as suggested by studies showing schizophrenia spectrum patients have more unfavourable outcomes compared to other psychotic disorders. The present study aimed to investigate whether basic self-disturbances and neurocognitive processes that have been linked to psychosis risk have discriminative power for schizophrenia spectrum disorders in patients presenting with first episode psychosis (FEP) and at ultra-high risk for psychosis (UHR). METHODS: 38 FEP patients, 48 UHR patients, and 33 healthy controls were assessed for basic self-disturbances (using the Examination of Anomalous Self-Experience, EASE, interview), source monitoring and aberrant salience (behavioural tasks to measure neurocognitive constructs). Clinical groups were divided into patients with schizophrenia spectrum disorders and those with other non-spectrum disorders and were further compared on measures controlling for symptom severity and age. RESULTS: Basic self-disturbances distinguished schizophrenia spectrum from non-spectrum disorders in the 'FEP only' sample, Fâ¯=â¯19.76, pâ¯<â¯0.001, η2partialâ¯=â¯0.37, and also in the combined UHR/FEP sample, Fâ¯=â¯23.56, pâ¯<â¯0.001, η2partialâ¯=â¯0.22. Additionally, some processes related to source monitoring deficits were elevated in schizophrenia spectrum disorders. In contrast, the two groups (schizophrenia spectrum vs other diagnoses) performed similarly in aberrant salience tasks. Comparable results were obtained for analyses performed with an FEP/UHR combined sample and the 'FEP only' sample. DISCUSSION: Basic self-disturbances at the phenomenological level and source monitoring deficits on the neurocognitive level may be useful in identifying risk of schizophrenia spectrum disorders at the earliest clinical presentation.

The literature has long emphasized the involvement of cortical and subcortical networks in executive function impairments among patients with schizophrenia. However, previous studies have not examined the relative involvement of monocular (mostly subcortical) versus binocular (mostly cortical) neural tracks in patients' EF deficits. Patients with schizophrenia and healthy comparisons were administered a dichotic version of the Stroop task, in which eye-of-origin manipulation was employed to isolate the involvement of monocular (mostly subcortical; thalamic regions) versus binocular (mostly cortical; extrastriate cortex) visual pathways. The eye-of-origin manipulation, in which a color patch (e.g., a green patch) was presented to one eye, and a word (e.g., "RED") to the other eye, enabled a split of the conflicting information between the two monocular channels. This results in the presentation of conflicting information to the higher cortical regions, but not to the lower subcortical structures. In the Stroop color task, when the monocular neural channels were not exposed to the conflicting information, the differences in task performance between the patients and the HCs significantly increased, and only the patients exhibited larger task conflict. When monocular neural channels were not exposed to the conflicting information, a robust dysfunction of the patients' group was observed. This abnormality might result from impairments in cortical regions or reduced computational power available for solving the conflict. However, additional studies that take into account the resolution of monocular and binocular neural channels are needed to enrich our understanding of the interplay between cortical and subcortical mechanisms in patients' EF deficits.
RESUMEN
The vast majority of men undergoing prostatectomy experience permanent retrograde ejaculation (RE). While newer, selective techniques of prostatectomy result in lower rates of RE by preserving the innervation to the urethra, the vast majority of men undergoing the classical techniques experience permanent RE due to destruction of the natural mechanisms preventing backflow of the ejaculate into the urinary bladder. A review of online information available to men reveals a lack of information on the importance of RE and explanation of the methods used for prostatectomy. This review provides evidence that the true effects of RE in men can be serious. With the lack of studies aiming at the psychological effects of RE on men's response, it is important for practicing family physicians and urologists to present RE as a serious adverse effect and not to trivialize it.

BACKGROUND AND AIMS: Adolescents at clinical high risk (CHR) for psychosis, as defined by the presence of attenuated psychosis symptoms (APS), exhibit increased levels of suicidal ideation and behaviour. However, no research thus far has examined the link between basic self-disturbances (SDs), an established marker for CHR, and suicidality/self-harm in this population. The goal of this pilot study was to assess the association between SD, depression and suicidal ideation and behaviour among non-help-seeking adolescents from the community. METHOD: A total of 100 community-dwelling adolescents (age range: 13-16) were assessed using the Examination of Anomalous Self-experience, Prodromal Questionnaire, Structured Interview for Prodromal Syndromes, Mood and Anxiety Symptom Questionnaire and the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS). The K-SADS was used to derive a binary diagnosis of unipolar depression, as well as to measure suicidal ideation and behaviour and self-harm. RESULTS: In a multiple regression analysis, SD accounted for variance in depressive symptoms and suicidality/self-harm over and above that accounted for by APS. Moreover, SD accounted for variance in suicidality/self-harm over and above that accounted for by depression symptoms. CONCLUSIONS: These pilot results suggest that SD might be a unique dimension of vulnerability to depression and suicidality/self-harm in adolescence. Also, they encourage assessment of SD as part of a suicide risk assessment, particularly in the context of risk for subsequent psychosis.

AIM: The goal of this pilot study was to assess the association between basic self-disturbance (SD) and deficits in neurocognitive and metacognitive functioning among help-seeking adolescents with and without attenuated psychosis syndrome (APS). METHODS: Sixty-one non-psychotic, help-seeking adolescents (age 13-18) were assessed with the examination of anomalous self-experience, the structured interview for prodromal syndromes and a new metacognitive approach to neurocognitive assessment applied to two non-social (executive functions and verbal memory) and two social (theory of mind and emotion recognition) domains. After each answer, subjects were also requested to indicate their level of confidence in the answer and to decide whether they desired it to be "counted" toward their total score on the task. Each volunteered answer earned a 5-cent gain if correct, but an equal fine if wrong. RESULTS: As hypothesized, metacognitive monitoring and control had a significant contribution to the prediction of SD over and above neurocognitive functioning and attenuated psychotic symptoms. However, the direction of this association was positive rather than negative. Also, inconsistent with or hypothesis, it was not moderated by the presence of APS. CONCLUSIONS: These pilot results provide preliminary support a modest association between SD and metacognition, which is not reducible to neurocognition and APS. In addition, they raise an intriguing possibility regarding metacognitive monitoring and control being indicators of hyper-reflectivity that characterizes individuals with SD. However, further research with larger samples and high-stress assessment conditions are needed to assess this possibility.

OBJECTIVES: To examine the association between attachment orientation and relationships with physicians and nurses among Israeli patients with advanced cancer. SAMPLE & SETTING: 52 patients with advanced cancer during active oncologic treatment. METHODS & VARIABLES: Eligible patients who agreed to participate in the study completed the Experience in Close Relationships Scale, Working Alliance Inventory-Short Revised, and a list of topics, which were defined by the research team as central and common to patients' coping. RESULTS: A correlation was found between avoidant attachment orientation and working alliance with nurses. In addition, patients' attachment orientation was found to be correlated with the type of topics they chose to share with the staff. IMPLICATIONS FOR NURSING: Knowledge regarding the theoretical concepts of attachment orientation may assist nurses in providing tailored and beneficial communication patterns with patients.

OBJECTIVES: A strong therapeutic alliance between cancer patients and medical staff is associated with treatment adherence, better health outcomes, and an emotional acceptance of a terminal illness. Given its significant role, the current study investigated the association between the working alliance and sharing concerns by advanced cancer patients. METHODS: Advanced cancer patients completed the Working Alliance Inventory-Short Revised and a checklist of topics in which they rated their degree of concern about the topics and the degree of sharing them with their physician/nurse. RESULTS: Fifty-two patients completed the study. The working alliance was found to be strong with respect to treating physicians and nurses. The four topics that concerned patients the most were family coping with their illness (81%), fear of future suffering (71%), symptom control (67%), and the oncological treatment (65%). Patients with a strong working alliance with their physician shared to a higher extent the personal and main concern regarding their family's coping, and a significant correlation was found between them (r = 0.53, p < .01). In addition, sharing fears of future suffering was also correlated with a strong working alliance with the physician (r = 0.28, p < .05). A strong working alliance with the nurse was correlated with discussing symptoms control (r = 0.30, p < .05). CONCLUSION: These findings provide preliminary support for an association between the strength of the working alliance and the type of concerns that advanced cancer patients choose to discuss with their medical staff and highlight the importance of follow-up studies to further explore this association.

The Two-Track Model of Bereavement Questionnaire (TTBQ) was designed to assess response to loss over time. Respondents were 354 persons who completed the 70-item self-report questionnaire constructed in accordance with the Two-Track Model of Bereavement. Track I focuses on the bereaved's biopsychosocial functioning and Track II concerns the bereaved's ongoing relationship to the range of memories, images, thoughts, and feeling states associated with the deceased. Factor analysis identified 5 factors that accounted for 51% of the variance explained. In accord with the theoretical and clinical model, 3 factors were primarily associated with the relationship to the deceased (Track II): Active Relational Grieving, Close and Positive Relationship, and Conflictual Relationship; and 2 factors with aspects of functioning (Track I): General Biopsychosocial Functioning and Traumatic Perception of the Loss. Construct and concurrent validity were examined and were found satisfactory. Differences by kinship, cause of death, gender, and time elapsed were examined across the 5 factors, the total TTBQ, and the ITG. The new measure is shown to have both construct and concurrent validity. Discussions of the results and implications for the measurement of response to loss conclude the article.

OBJECTIVE: Postpartum depressive disorders are common and symptoms may appear as early as the first 2 weeks postpartum. Data regarding hormone-related risk factors for depressive symptoms occurring in the very early postpartum period are scarce and may be of importance in identifying serious postpartum illness. We examined the association between the reported history of psychiatric symptoms of possible hormonal etiology and very early postpartum depressive symptoms. METHODS: All women (n= 1,800) in a general hospital maternity ward were assessed during the first 3 days after parturition for potential risk factors for postpartum depressive disorders by a self-reported questionnaire and for present mood symptoms (Edinburgh Postnatal Depression Scale, EPDS). The associations between potential risk factors and postpartum depressive symptoms were analysed. RESULTS: The incidence of women with an EPDS >or=10 was 6.8% (88/1,286). Significant risk factors for early postpartum depressive symptoms were a history of mental illness including past postpartum depression (PPD), premenstrual dysphoric disorder (PMDD), and mood symptoms during the third trimester. CONCLUSION: In accordance with other studies, a history of depression was found to be a risk factor for early postpartum mood symptoms. An association was also found between some risk factors of possible hormone-related etiology such as PMDD and third trimester mood symptoms and early postpartum mood symptoms. As such, early postpartum symptoms may indicate vulnerability to subsequent PPD; it may be of importance to assess these risk factors and mood immediately after parturition. A prospective study is needed to determine which of these risk factors is associated with progression to PPD and which resolves as the blues.

BACKGROUND: Various factors have been reported to be associated with the development of postpartum mood disorders. The relationship between postpartum mood disorders and putatively hormone-related phenomena such as premenstrual dysphoric disorder (PMDD) is unclear. This study attempts to determine whether such mood phenomena are risk factors for postpartum mood disorders. METHODS: Postpartum women (n=1800) were assessed for risk factors for postpartum mood disorders during the first 2-4 days after parturition. Of these, 133 were defined as "high risk" and 109 as "low risk" according to fixed criteria. A structured phone diagnostic interview was performed at 6-8 weeks postpartum to assess for the presence of postpartum depression or the blues. RESULTS: Premenstrual dysphoric disorder (PMDD), mood symptoms during the first 2-4 days postpartum, a past history of depression and mood symptoms during past oral contraceptive use, were found to be significant risk factors for postpartum mood disorders. Women at high risk for postpartum mood disorders had a 9.3-, 1.5-, 1.6- and 2.6-fold increase in risk for major depression, minor depression, the blues and adjustment disorder respectively compared to women at low risk. LIMITATIONS: While the study design is prospective, it is limited by the retrospective assessment of risk factors. CONCLUSIONS: This study provides preliminary evidence that putatively hormone-related phenomena such as PMDD are related to the occurrence of postpartum mood disorders. The results go some way to support the hypothesis that the etiology for postpartum mood disorders may be related to differential hormonal sensitivity. Such risk factors should be included in any assessment of the risk for these disorders.
