The Maturational Processes and the Facilitating Environment

We examined the influence of gender on the polysomnographic features of obstructive sleep apnea (OSA) in a retrospective study of 830 patients with OSA diagnosed by overnight polysomnography (PSG). The severity of OSA was determined from the apnea- hypopnea index (AHI) for total sleep time (AHI(TST)), and was classified as mild (5 to 25 events/h), moderate (26 to 50 events/h), and severe (> 50/events/h). Differences in OSA during different stages of sleep were assessed by comparing the AHI during non-rapid eye movement (NREM) (AHI(NREM)) and rapid eye movement (REM) (AHI(REM)) sleep and calculating the "REM difference" (AHI(REM) - AHI(NREM)). Additionally, each overnight polysomnographic study was classified as showing one of three mutually exclusive types of OSA: (1) mild OSA, which occurred predominantly during REM sleep (REM OSA); (2) OSA of any severity, which occurred predominantly in the supine position (S OSA); or (3) OSA without a predominance in a single sleep stage or body position (A OSA). The mean AHI(TST) for men was significantly higher than that for women (31.8 +/- 1.0 versus 20.2 +/- 1.5 events/h, p < 0. 001). The male-to-female ratio was 3.2:1 for all OSA patients, and increased from 2.2:1 for patients with mild OSA to 7.9:1 for those with severe OSA. Women had a lower AHI(NREM) than did men (14.6 +/- 1.6 versus 29.6 +/- 1.1 events/h, p < 0.001), but had a similar AHI(REM) (42.7 +/- 1.6 versus 39.9 +/- 1.2 events/h). Women had a significantly higher REM difference than did men (28.1 +/- 1.5 versus 10.3 +/- 1.1 events/h, p < 0.01). REM OSA occurred in 62% of women and 24% of men with OSA. S OSA occurred almost exclusively in men. We conclude that: (1) OSA is less severe in women because of milder OSA during NREM sleep; (2) women have a greater clustering of respiratory events during REM sleep than do men; (3) REM OSA is disproportionately more common in women than in men; and (4) S OSA is disproportionately more common in men than in women. These findings may reflect differences between the sexes in upper airway function during sleep in patients with OSA.

In this study, we examine the direct and vicarious impact of the social processes of felt and enacted stigma and their impact on the lives of individuals with disabilities and their families. Specifically, findings of interactive interviews with eight adults with disabilities and seven mothers of children with disabilities were analyzed for themes related to components of stigma described by Link and Phelan (2001): labeling, stereotyping, separation, status loss, and discrimination within the context of power differential. Findings suggest that while these social processes can have important negative psychosocial consequences for individuals living with disabilities, the severity of the consequences varies among the components. Findings also indicate that these individuals find varied and creative ways to resist and actively counter the negative effects of stigma in their lives. Findings support the complexity of the experience of stigma and the importance of the socio/cultural context to the lived experience of disability.

Postwar: A History of Europe Since 1945

As advances in neuroscience have furthered our understanding of the role of brain circuitry, genetics, stress, and neuromodulators in the regulation of normal behavior and in the pathogenesis of psychopathology, an increasing appreciation of the role of neurobiology in individual differences in personality and their pathology in personality disorders has emerged. Individual differences in the regulation and organization of cognitive processes, affective reactivity, impulse/action patterns, and anxiety may in the extreme provide susceptibilities to personality disorders such as borderline and schizotypal personality disorder. A low threshold for impulsive aggression, as observed in borderline and antisocial personality disorders, may be related to excessive amygdala reactivity, reduced prefrontal inhibition, and diminished serotonergic facilitation of prefrontal controls. Affective instability may be mediated by excessive limbic reactivity in gabaminergic/glutamatergic/cholinergic circuits, resulting in an increased sensitivity or reactivity to environmental emotional stimuli as in borderline personality disorder and other cluster B personality disorders. Disturbances in cognitive organization and information processing may contribute to the detachment, desynchrony with the environment, and cognitive/perceptional distortions of cluster A or schizophrenia spectrum personality disorders. A low threshold for anxiety may contribute to the avoidant, dependent, and compulsive behaviors observed in cluster C personality disorders. These alterations in critical regulatory domains will influence how representations of self and others are internalized. Aspects of neurobiological functioning themselves become cognized through the medium of figurative language into an ongoing narrative of the self, one that can be transformed through the analytic process, allowing for the modulation of genetic/biological thresholds.

The neurobiology of personality disorders: implications for psychoanalysis.

Determinants of daytime sleepiness include sleep length, sleep continuity, and circadian factors. Sleep stage composition has not been seen as influencing subsequent daytime functioning; however, earlier studies did not focus explicitly on sleepiness. The present experiment studied the effects of selective sleep-stage restriction on an objective measure of sleep tendency, and explored the relationship between sleepiness and subsequent REM recurrence during REM deprivation. Daytime sleep latency was measured by a modified Multiple Sleep Latency Test prior to and following two nights of awakenings from either REM or Stage 2 sleep in 16 normal young adults. Sleep latency following these awakenings was also measured. REM sleep and Stage 2 awakenings produced comparable levels of sleepiness, both during the Awakening Nights and subsequent daytime Multiple Sleep Latency Testing. Pooling the groups, daytime and nocturnal sleepiness measures were correlated within individuals. In the REM-Awakening Group, Pre-Awakening daytime sleepiness was associated with the tendency for REM sleep to recur following experimental awakenings. Comparable levels of sleepiness may result from nonspecific processes such as sleep curtailment and fragmentation, or alternatively from separate REM and Stage 2 mechanisms. The relationship between REM sleep and sleepiness is discussed in the context of both state and trait models.

Sleepiness and REM sleep recurrence: the effects of stage 2 and REM sleep awakenings.

Recent literature suggests that how the self is represented is a cardinal aspect of the dream experience. A review of studies of phasic-tonic distinctions within rapid eye movement (REM) sleep revealed that increasing self-participation marked awakenings from phasic intervals. Five scales specifically designed to measure absorption in dreaming were compared with three scales previously shown to discriminate phasic from tonic awakenings within REM sleep. Eight reports per night (two stage REM, six stage 2) were collected from each of 20 subjects on 4 baseline nights. Awakenings were controlled for time into the REMP and time of night, correcting the methodological flaws of previous studies in this area. Scales developed to measure self-participation were able to discriminate phasic from tonic awakenings better than those already in the literature. Results are discussed in terms of the psychometric properties of the individual scales.

The development of scales to measure the experience of self-participation in sleep.

Middle childhood is a pivotal time in character development during which enduring internal structures are formed. Fiction can offer insights into the cognitive and affective shifts of this developmental phase and how they are transformed in adulthood. While the success of beloved books for latency age children lies in the solutions they offer to the conflict between the pull toward independence and the pull back to the safety of childhood, the enduring stories for adults about children in their middle years can be seen as works of mourning for the relationship with the parents and the childhood self, but more importantly as attempts to transform their experience of middle childhood through the retrospective creation of a coherence that was initially absent. Thematic and structural elements distinguish two groups of stories for adults: the first appears to solve the conflicts of this period by importing adult knowledge and perspective into the narrative of childhood; the second describes the unconscious disorganizing aspects of this period, thereby offering readers a chance to reorganize their own memories, to make a coherent whole out of the fragmented, the confusing, and the unresolved.
