Utilizing a Phenomenological Approach to Examine the Experience of Sexuality for Women Concerned about Urinary Incontinence following Spinal Cord Injury

Sexuality after spinal cord injury (SCI) is a complex issue that is influenced by a number of social, psychological and physiological factors, one of which is urinary incontinence (UI). Using a phenomenological approach, seven mixed methods interviews combining both the interview guide and standardized open-ended approaches were conducted to examine the experience of sexuality for women who are concerned about UI following SCI. Sexual function was one of the top priorities for the women after SCI, and UI was one of the main concerns the women had regarding sexuality. The findings of this study demonstrate that various dimensions of intimacy and the sexual experience as a whole were affected by UI, and the women discussed both physical and psychological concerns. The main issues regarding sexuality included concerns related to relationships, frustrations with limited sexual activities and the difficulty of being sexually satisfied, the number of unanswered questions and concerns, and a fear of being hurt or injured while participating in sexual activities. The main concerns regarding UI were embarrassment, the work and inconvenience involved with the clean-up of UI, bladder infections, the lack of accessible washrooms, and the negative effects of UI medications. When examining sexuality and UI together, the major issues were the constant comparison to the way things were before SCI, as well as the new concerns that the women did not have to worry about previously, worrying about how their partner would react if UI were to occur during sexual activity, and the impact of their own feelings toward UI on sexuality, a connection between pleasurable sexual sensations and UI as well as difficulty differentiating between the sensation of UI with the sensation of UI, dealing with infected urine during sexual activity, having to discuss UI with a new potential sexual partner, and a fear of rejection. Other identified issues included those related to body image, a lack of resources, Doctors who were inadequately educated regarding SCI, and issues related to both having and raising children. There is a significant shortage of information available for women with SCI to use as a resource regarding sexual function in general, and sexual function as it relates to UI. It is necessary that future work focus on creating resources to assist in this area, and that the dissemination of those resources becomes both appropriate and effective. Addressing sexual function and UI which are among the top concerns for this population has the opportunity to greatly improve quality of life (QOL) for these individuals.

Microfacies analysis of the lower paleocene beda formation in Western Concession 59 and Block 59F, Sirte Basin, Libya /

The rock sequence of the Tertiary Beda Formation of S. W. concession 59 and 59F block in Sirte Basin of Libya has been subdivided into twelve platformal carbonate microfacies. These microfacies are dominated by muddy carbonates, such as skeletal mudstones, wackestones, and packstones with dolomites and anhydrite. Rock textures, faunal assemblages and sedimentary structures suggest shallow, clear, warm waters and low to moderate energy conditions within the depositional shelf environment. The Beda Formation represents a shallowing-upward sequence typical of lagoonal and tidal flat environments marked at the top by sabkha and brackish-water sediments. Microfossils include benthonic foraminifera, such as miliolids, Nummulites, - oerculina and other smaller benthonics, in addition to dasycladacean algae, ostracods, molluscs, echinoderms, bryozoans and charophytes. Fecal pellets and pelloids, along with the biotic allochems, contributed greatly to the composition of the various microfacies. Dolomite, where present, is finely crystalline and an early replacement product. Anhydrite occurs as nodular, chickenwire and massive textures indicating supratidal sabkha deposition. Compaction, micr it i zat ion , dolomit izat ion , recrystallization, cementation, and dissolution resulted in alteration and obliteration of primary sedimentary structures of the Beda Formation microfacies. The study area is located in the Gerad Trough which developed as a NE-SW trending extensional graben. The Gerad trough was characterized by deep-shallow water conditions throughout the deposition of the Beda Formation sediments. The study area is marked by several horsts and grabens; as a result of extent ional tectonism. The area was tectonically active throughout the Tertiary period. Primary porosity is intergranular and intragranular, and secondary processes are characterized by dissolution, intercrystalline, fracture and fenestral features. Diagenesis, through solution leaching and dolomitization, contributed greatly to porosity development. Reservoir traps of the Beda Formation are characterized by normal fault blocks and the general reservoir characteristics/properties appear to be facies controlled.

The Role of Orexin-A in Anxiety and the Emission of Ultrasonic Vocalizations in Rats

Central administration of orexin-A has been shown to activate autonomic arousal in rats, reliably inducing anxiety-like behaviours in the open field. To date, there has yet to be a study investigating the role of orexin-A in the communication of such negative affective state. In the current study, forty-six adult male rats were chronically cannulated and administered orexin-A into the medial preoptic area/anterior hypothalamic area to determine the effect of this neuropeptide on anxiety-like behaviour and the production of 22 kHz aversive ultrasonic vocalizations. It was found that intracerebral administration of orexin-A increased autonomic arousal as measured by a significant increase in fecal boli output, however orexin-A did not significantly affect locomotor activity or induce 22 kHz calling. These data suggest that orexin-A is involved in the regulation of the autonomic aspect of anxiety-like behaviour but not in the vocal communication of such negative affect
