The psychosocial impact of cancer-related infertility on women: a review and comparison.

The objective of the current article was to assess the psychosocial impact of treatment-related infertility or the possibility of infertility on young women with cancer in contrast to the general population. Literature on the subject of female infertility among the general population and treatment-related female infertility among young women with cancer was identified and examined in the context of what is known about the psychosocial impact of infertility among the general population. Women whose fertility was affected by cancer treatment were likely to experience negative emotional reactions, which can strain their relationships. Additional concerns included receiving inadequate information about infertility, enduring distress, and feeling uncertainty regarding fertility status.

Fertility and cancer--a qualitative study of Australian cancer survivors.

PURPOSE: This study aims to assess the fertility concerns among cancer survivors aged 50 and under as part of a larger study investigating the survivors' concerns regarding fertility, sexuality and parenting. METHODS: Cancer survivors who were at least 1 month post-treatment were invited to a recorded interview. The patients were identified from an oncology database and invited to participate via letter or during clinic consultation. The participants were recruited until saturation of themes was achieved. Transcripts were coded thematically, with greater emphasis given to frequently raised themes. RESULTS: Twenty-five survivors (19 women) were interviewed. The median age was 37 (range 24-50). Median time since completion of treatment was 7 months. Twenty were married or in a relationship; 18 had children at the time of diagnosis. Two became pregnant after treatment. Four themes were identified: (1) Fertility represents more than child-bearing capacity: potential fertility loss was a concern for participants, irrespective of their desire for future children; (2) Assumed infertility: There was a tendency for participants to assume that they were infertile; (3) Lack of information regarding decision-making and fertility: The respondents reported a perceived lack of consideration of fertility at diagnosis by medical professionals, and this impacted upon the decision-making process; and (4) Participant recommendations: The respondents wanted more information and for support services to be offered. CONCLUSIONS: Fertility is an important concern for young cancer survivors. There is a need for strategies regarding information provision and support for cancer patients with regard to these concerns.

Evidence-based medicine evaluation of electrophysiological studies of the anxiety disorders.

We provide a systematic, evidence-based medicine (EBM) review of the field of electrophysiology in the anxiety disorders. Presently, electrophysiological studies of anxiety focus primarily on etiological aspects of brain dysfunction. The review highlights many functional similarities across studies, but also identifies patterns that clearly differentiate disorder classifications. Such measures offer clinical utility as reliable and objective indicators of brain dysfunction in individuals and indicate potential as biomarkers for the improvement of diagnostic specificity and for informing treatment decisions and prognostic assessments. Common to most of the anxiety disorders is basal instability in cortical arousal, as reflected in measures of quantitative electroencephalography (qEEG). Resting electroencephalographic (EEG) measures tend to correlate with symptom sub-patterns and be exacerbated by condition-specific stimulation. Also common to most of the anxiety disorders are condition-specific difficulties with sensory gating and the allocation and deployment of attention. These are clearly evident from evoked potential (EP) and event-related potential (ERP) electrical measures of information processing in obsessive compulsive disorder (OCD), post-traumatic stress disorder (PTSD), panic disorder (PD), generalized anxiety disorder (GAD) and the phobias. Other'ERP measures clearly differentiate the disorders. However, there is considerable variation across studies, with inclusion and exclusion criteria, medication status and control group selection not standardized within condition or across studies. Study numbers generally preclude analysis for confound removal or for the derivation of diagnostic biomarker patterns at this time. The current trend towards development of databases of brain and cognitive function is likely to obviate these difficulties. In particular, electrophysiological measures of function are likely to play a significant role in the development and subsequent adaptations of DSM-V and assist critically in securing improvements in nosological and treatment specificity.

Fronto-temporal alterations within the first 200 ms during an attentional task distinguish major depression, non-clinical participants with depressed mood and healthy controls: a potential biomarker?

Attentional impairment in depression is a cardinal feature of depression and has been proposed as a candidate endophenotype for major depressive disorder. Event-related potentials (ERPs) elicited by oddball signal detection tasks provide objective markers of selective stimulus processing, and are pertinent endophenotypic markers for depression. While previous studies have sought to determine objective markers for attentional impairment in depression, evidence is inconsistent and may involve heterogeneity in relatively small samples. Here, we brought together oddball ERP recording with source localization of neural correlates of selective attention in outpatients with major depressive disorder (MDD; n = 78) and participants with depressed mood (PDM; n = 127) relative to healthy controls (CTL; n = 116). The key finding was a dimensional exaggeration of the P200 (140-270 ms) to both target (signal) and non-target (noise) stimuli, most pronounced in MDD, followed by PDM, relative to CTL. This exaggeration was coupled with slower and more variable response times, suggesting that neural systems are attempting to compensate for a difficulty in discriminating signal from noise. P200 alterations were localised to limbic (hippocampal), temporal and ventral prefrontal regions, key components of the signal detection network. A subsequent reduction and delay in the P300 was also revealed for MDD indicating that the pronounced lack of discrimination in clinical depression may also lead to impaired stimulus evaluation. This P200 increase in depression could provide a potential mechanism for the attentional impairment frequently observed in depression and consequent alterations in the P300 may differentiate clinically significant depression.
