Selected AbstractsEating disorders and attachment: the effects of hidden family processes on eating disorders,EUROPEAN EATING DISORDERS REVIEW, Issue 2 2007Francoise Ringer Abstract Aim This study examined pattern of attachment in cohort of women with an eating disorder to determine what types of self-protective strategies they used, and further whether there was a specific relationship between strategy and diagnosis. Method The participants were 62 young women with an eating disorder (19 with anorexia nervosa, 26 with bulimia nervosa and 17 with bulimic anorexia). Attachment was assessed using the Adult attachment interview (AAI), classified using Crittenden's Dynamic-Maturational Method. Results The results indicated that all women with an eating disorder were anxiously attached. About half used an extreme coercive Type C strategy while most of the others combined coercion with an extreme dismissing Type A strategy. The content of the AAIs suggested lack of resolution of trauma or loss among the mothers and also of hidden family conflict between the parents. This in turn elicited extreme strategies for generating parent,child contingency from the daughters. Conclusions Central in almost all cases was the women's confusion regarding how parental behaviour was tied causally to their own behaviour. Questions are raised regarding the focus of treatment.

[source] Coloured overlays and their benefit for readingJOURNAL OF RESEARCH IN READING, Issue 1 2001Arnold Wilkins Children in mainstream schools compared text on white paper with identical text covered in turn by each of ten differently-coloured plastic overlays. More than 50% reported improved perception with one or more colours, and were given the best colour to use. About half used the overlays for more than three months and their reading speed increased when the overlays were used. In Study I children were examined twice using different methods and examiners. 47% chose the same colour on both occasions, and showed the greatest improvement in reading fluency, reliable at retest. In Study II children were issued with a random colour, and the greatest improvements in reading speed occurred when the random colour was the same as that previously chosen. Phonological reading strategies were not related to visual symptoms, or the benefit from overlays. Across individuals, reading speed varied by a factor of more than three, for good and poor readers. Study III provided estimates of the prevalence of improvements based on a sample of 426 children from 12 schools: 5% of children read more than 25% faster with a coloured overlay. [source] Skin benefits from continuous topical administration of a zinc oxide/petrolatum formulation by a novel disposable diaperJOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 2001S Baldwin Abstract Background Diaper dermatitis is a common childhood affliction. Aiming to help reduce the prevalence of this problem, we have advanced in our development of a novel diaper that delivers dermatological formulations to help protect the skin from over-hydration and irritation. Objective To determine the clinical benefits of a novel disposable diaper designed to deliver a zinc oxide and petrolatum-based formulation continuously to the skin during use. Methods All studies were independent, blinded, randomized clinical trials. Study A was conducted to confirm transfer of the zinc oxide/petrolatum (ZnO/Pet) formulation from the diaper to the child's skin during use. Children wore a single diaper for 3 h or multiple diapers for 24 h. After the use period, stratum corneum samples were taken from each child and analysed for ZnO/Pet. Study B evaluated the prevention of skin irritation and barrier damage from a standard skin irritant (SLS) in an adult arm model. Study C evaluated skin erythema and diaper rash in 268 infants over a 4-week usage period. One half of the infants used the ZnO/Pet diaper, while the other half used a control diaper that was identical except for the absence of the ZnO/Pet formulation. Results The ointment formulation and ZnO transferred effectively from the diaper to the child's skin during product use. Transfer of ZnO increased from 4.2 µg/cm2 at 3 h to > 8 µg/cm2 at 24 h. Exposure to the formulations directly on adult skin prior to an irritant challenge was associated with up to a 3.5 reduction in skin barrier damage and skin erythema. Greatest reductions were seen for the ZnO containing formulations. Wearing of the formulation treated diaper was also associated with a significant reduction in skin erythema and diaper rash compared to the control product. Conclusions The results demonstrated the clinical benefits associated with continuous topical administration of a zinc oxide/petrolatum-based formulation by this novel diaper. [source] An Improved Non-Isothermal Kinetic Model for Prediction of Extent of Transesterification Reaction and Degree of Randomness in PET/PEN BlendsMACROMOLECULAR THEORY AND SIMULATIONS, Issue 4-5 2008Mahdi Golriz Abstract An improved non-isothermal kinetic model was developed based on mass balance and Arrhenius laws using a second-order reversible reaction capable of predicting the extent of transesterification reaction (X) and the degree of randomness (RD) in poly(ethylene terephthalate) (PET)/poly(ethylene naphthalene-2,6-dicarboxylate) (PEN) blends prepared by a twin screw micro-compounder over a full composition range under different processing conditions. The experimental values of X and RD were determined by 1H-NMR and a direct relationship between them developed. The model constants were tuned by an optimization method using half of the experimental data, with the other half used for verification. Good agreement was found between the experimental and theoretical data in the verification stage and, therefore, it was concluded that the model is capable of predicting the extent of transesterification reaction with a high level of confidence for a wide range of processing conditions. Similarly to the experimental results, the model showed that, among all parameters affecting the extent of transesterification reaction, the time and temperature play the major role, whereas the blend composition does not have a significant role. [source] Infertility in Australia circa 1980: an historical population perspective on the uptake of fertility treatment by Australian women born in 1946-51AUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 6 2009Danielle L. Herbert Abstract Objective: To estimate the prevalence of lifetime infertility in Australian women born in 1946-51 and examine their uptake of treatment. Methods: Participants in the Australian Longitudinal Study on Women's Health born in 1946-51 (n=13,715) completed up to four mailed surveys from 1996 to 2004. The odds of infertility were estimated using logistic regression with adjustment for socio-demographic and reproductive factors. Results: Among participants, 92.1% had been pregnant. For women who had been pregnant (n=12738): 56.5% had at least one birth but no pregnancy loss (miscarriage and/or termination); 39.9% experienced both birth and loss; and 3.6% had a loss only. The lifetime prevalence of infertility was 11.0%. Among women who reported infertility (n=1511), 41.7% used treatment. Women had higher odds of infertility when they had reproductive histories of losses only (OR range 9.0-43.5) or had never been pregnant (OR=15.7, 95%CI 11.8-20.8); and higher odds for treatment: losses only (OR range 2.5-9.8); or never pregnant (1.96, 1.28-3.00). Women who delayed their first birth until aged 30+ years had higher odds of treatment (OR range 3.2-4.3). Conclusions: About one in ten women experienced infertility and almost half used some form of treatment, especially those attempting pregnancy after 1980. Older first time mothers had an increased uptake of treatment as assisted reproductive technologies (ART) developed. Implications: This study provided evidence of the early uptake of treatment prior to 1979 when the national register of invasive ART was developed and later uptake prior to 1998 when data on non-invasive ART were first collected.
