ABSTRACT

ABSTRCTBackground: Parents continue to support to autistic university students, and consequently, experience considerable stress.Aim: To explore the experiences of parents of specialist peer mentored university students and to examine these using the ICF as a theoretical framework.Method: Thirteen semi-structured interviews were completed and analyzed using thematic analysis. Directive content analysis linked the data to the ICF core set for autism spectrum disorders (ASD).Results: Five interrelated themes emerged: The mentoring relationship is a facilitator, Developing skills for university, Mentoring changes lives, Mentoring is not a substitute for other supports, and University is an emotional rollercoaster. Specialist peer mentoring was linked to Activity and Participation (44%) and Environmental factors (32%) of the ICF core set for ASD.Conclusion: These results add to the specialist peer mentoring evidence-base, and indicate perceived benefits for autistic university students and their parents. An unintended consequence was that parents broadened their participation in activities.

ABSTRACT

Background: Despite recognition of the benefits of post-school education in improving life outcomes for autistic adults their university completion rates remain low.Aim: To explore the experiences of undergraduate autistic university students participating in specialist peer mentoring (SPM) to identify active ingredients in the peer mentoring process and to examine the impact of SPM on social communication.Material and method: A total of 30 (8 female; M age = 22.3; SD = 6.7) undergraduate autistic university students engaged in SPM participated in this study. A quantitative pre-test post-test design examined changes in autistic traits. In parallel, the experiences of participating in SPM were explored through semi-structured interviews.Results: Improvements were noted at post-test on the Social Responsiveness Scale-2 total score p = 0.02), and its Social Communication, (p = 0.03) and Social Motivation (p = 0.03) sub-scales. Four themes emerged from the interviews: Developing Partnership and Understanding, Modelling and Practising Communication, Psychological Support and Grading and Planning Skills.Conclusions: These results indicated that the mentor-mentee partnership was a crucial active ingredient of SPM. This partnership appeared to modify social cognition and motivation for autistic university students through modelling and practising communication.Significance: These results demonstrate that SPM can support participation at university for autistic university students.

ABSTRACT

Difficulties in Facial Emotion Recognition (FER) are commonly associated with individuals diagnosed with Autism Spectrum Disorder (ASD). However, the mechanisms underlying these impairments remain inconclusive. While atypical cortical connectivity has been observed in autistic individuals, there is a paucity of investigation during cognitive tasks such as FER. It is possible that atypical cortical connectivity may underlie FER impairments in this population. Electroencephalography (EEG) Imaginary Coherence was examined in 22 autistic adults and 23 typically developing (TD) matched controls during a complex, dynamic FER task. Autistic adults demonstrated reduced coherence between both short and long range inter-hemispheric electrodes. By contrast, short range intra-hemispheric connectivity was increased in frontal and occipital regions during FER. These findings suggest altered network functioning in ASD.

ABSTRACT

PURPOSE: The morphology of the proximal femur has been extensively studied in the adult population. However, no literature providing a comprehensive evaluation of the anatomy in paediatric patients exists. The current study aims to characterize such anatomy in skeletally-immature patients, examine potential differences between genders, and analyze how these anatomical parameters change with age. METHODS: Cadaveric femurs from the Hamann-Todd Osteological Collection were examined. Specimens with open physes and no skeletal disease or deformity were included for analysis. Age and gender were recorded for each specimen. Each femur was photographed in standardized modified axial and anteroposterior views. In all, 14 proximal femoral anatomical parameters were measured from these photographs. Comparisons between genders and age were calculated. RESULTS: A total of 43 femurs from ages four to 17 years met inclusion criteria. The majority were female (56%); no difference existed in age between genders (p = 0.62). The specimens had a neutral mean neck-shaft angle (130.7º) and anteversion (12.8º), and the sphericity of the ossified femoral heads was symmetrical. Male specimens had significantly higher alpha angles (p = 0.01), posterior offset (p = 0.02), neck width (p = 0.04) and head-neck length ratio (p = 0.02) values than female specimens. Strong positive correlations exist between length/size parameters and age, while negligible correlations were noted for angular measurements. CONCLUSIONS: This study establishes reference values for a comprehensive list of anatomical parameters for the skeletally-immature ossified proximal femur. It highlights gender differences in morphology and demonstrates that angular characteristics remain relatively stable while length parameters generally increase with age. LEVEL OF EVIDENCE: Level III Diagnostic.

ABSTRACT

BACKGROUND: The need to identify strategies that facilitate involvement in physical activity for children and youth with disabilities is recognised as an urgent priority. This study aimed to describe the association between context, mechanisms and outcome(s) of a participation-focused physical activity intervention to understand what works, in what conditions, and how. METHODS: This study was designed as a realist evaluation. Participant recruitment occurred through purposive and theoretical sampling of children and parents participating in the Local Environment Model intervention at Beitostolen Healthsports Centre in Norway. Ethnographic methods comprising participant observation, interviews, and focus groups were employed over 15 weeks in the field. Data analysis was completed using the context-mechanism-outcome framework of realist evaluation. Context-mechanism-outcome connections were generated empirically from the data to create a model to indicate how the program activated mechanisms within the program context, to enable participation in physical activity. RESULTS: Thirty one children with a range of disabilities (mean age 12y 6 m (SD 2y 2 m); 18 males) and their parents (n = 44; 26 mothers and 18 fathers) participated in the study. Following data synthesis, a refined program theory comprising four context themes, five mechanisms, and six outcomes, were identified. The mechanisms (choice, fun, friends, specialised health professionals, and time) were activated in a context that was safe, social, learning-based and family-centred, to elicit outcomes across all levels of the International Classification of Functioning, Disability and Health. CONCLUSIONS: The interaction of mechanisms and context as a whole facilitated meaningful outcomes for children and youth with disabilities, and their parents. Whilst optimising participation in physical activity is a primary outcome of the Local Environment Model, the refined program theory suggests the participation-focused approach may act as a catalyst to promote a range of outcomes. Findings from this study may inform future interventions attempting to enable participation in physical activity for children and youth with disabilities.

ABSTRACT

BACKGROUND: Women who experience significant premenstrual symptoms differ in the extent to which these symptoms cause cyclical impairment. This study clarifies the type and number of symptoms that best predict premenstrual impairment in a sample of women undergoing prospective assessment for premenstrual dysphoric disorder (PMDD) in a research setting. Central research goals were to determine (1) which emotional, psychological, and physical symptoms of PMDD are uniquely associated with premenstrual impairment, and (2) how many cyclical symptoms optimally predict the presence of a clinically significant premenstrual elevation of impairment. METHOD: A total of 267 naturally cycling women recruited for retrospective report of premenstrual emotional symptoms completed daily symptom reports using the Daily Record of Severity of Problems (DRSP) and occupational, recreational, and relational impairment for 1-4 menstrual cycles (N = 563 cycles). RESULTS: Multilevel regression revealed that emotional, psychological, and physical symptoms differ in their associations with impairment. The core emotional symptoms of PMDD were predictors of impairment, but not after accounting for secondary psychological symptoms, which were the most robust predictors. The optimal number of premenstrual symptoms for predicting clinically significant premenstrual impairment was four. CONCLUSION: Results enhance our understanding of the type and number of premenstrual symptoms associated with premenstrual impairment among women being evaluated for PMDD in research contexts. Additional work is needed to determine whether cognitive symptoms should receive greater attention in the study of PMDD, and to revisit the usefulness of the five-symptom diagnostic threshold.

ABSTRACT

BACKGROUND: Somatosensory modalities, such as touch, proprioception and haptic ability, greatly influence the achievement of developmental milestones for children. Describing somatosensory impairment, natural variability and typical or expected developmental changes across age groups will help establish frameworks for intervention in clinical populations. This systematic review aimed to determine how different somatosensory modalities develop across childhood into adolescence to use as a point of reference for children at risk of somatosensory impairment. METHODS: Searches of five electronic databases were undertaken through EBSCO-host (MEDLINE, CINAHL, PsycINFO, SPORTDiscus and ERIC) for studies measuring at least one somatosensory modality in typically developing individuals between birth and 18 years and analysed by age. Characteristics of studies were collected including country of origin, sample size, demographics and outcome measure used. Quality assessment and data extraction were performed by two independent reviewers. RESULTS: Twenty three cross-sectional studies were included from a total of 188 articles retrieved: 8 examined aspects of touch, 5 proprioception and 10 haptic ability. Variability of study designs and variation in assessment tools precluded any formal meta-analysis. CONCLUSIONS: Somatosensation matures through childhood into adolescence; however, the present review found the pattern of somatosensory development varied depending on the assessment tool used and the aspect of somatosensation being measured, making it difficult to describe typical performance. There is a need for comprehensive assessment batteries to measure the somatosensation, including touch, proprioception and haptic ability, of children at risk of somatosensory impairment to aid in the development of effective interventions.

ABSTRACT

Investigating cognitive development of children poses interesting challenges pertaining to emergence of children's' ability to think and understand. Psychological tasks that involve conflict, like the Flanker task, are widely used to understand development of response conflict processes. In this study, EEG signals were used to examine the coherence and imaginary part of coherency within the delta, theta, alpha and beta bands across different conditions of the Flanker task. Longitudinal data were collected from a group of typically developing children at ages of seven and nine. We found that the imaginary part of coherency was more helpful in distinguishing between stimuli - alpha and beta bands resulted in 90.90% classification rate in seven year old children. The beta and theta bands were found to be more effective for stimuli classification in nine year old children - more than 84.09% classification accuracy was achieved.

ABSTRACT

AIM: To investigate the relationship between functioning and post-school day occupation for young adults with Down syndrome. METHODS: Families of young people with Down syndrome (n = 269) aged 15-30 years in 2009 were recruited from the population-based Down syndrome 'Needs Opinion Wishes' database in Western Australia. Questionnaires were mailed to participating families and involved two parts, young person characteristics and family functioning; 203 were returned (75%). Of those families who returned questionnaires, 164 (80.8%) of their young adults had left school. Participation in post-school day occupations was the main outcome and included; open employment, training, sheltered employment or alternatives to employment (ATE). RESULTS: Young adults were reported as participating in open employment (n = 42), training (n = 17), sheltered employment (n = 64) or ATE (n = 41) post-school. Those who reported better functioning in self-care, community and communication skills were more likely to be in open employment and/or attending Technical and Further Education compared with those attending sheltered employment and/or ATE after adjusting for age, gender and rural/metropolitan regions. Current health as measured by visits to a general practitioner (GP) and hospitalizations revealed a weak relationship with post-school day occupations, with increasing likelihood of participating in open employment or training with increasing hospitalizations and GP visits. CONCLUSIONS: Our analysis shows that functioning in activities of daily living was related to post-school day occupation. Current health status and behaviour were found to have a weak relationship with post-school day occupation adjusting for functioning in the final model.

ABSTRACT

PURPOSE: The purpose of this review was to describe literature relating to transition for young people with an intellectual disability and identify gaps within the current knowledge base. METHOD: A narrative literature review was undertaken. Searches of databases Medline, CINAHL, PsycINFO, ERIC, ISI Web of Science and ProQuest 500 International provided relevant research articles. The search terms used were intellectual disability, transition, employment, and ICF as well as other terms derived from the ICF. Manual searches of reference lists identified additional studies. Furthermore, government websites were searched for relevant reports and policies. RESULTS: Transition literature was explored by ICF domains; body functions and structures, activity and participation and contextual factors. Studies were identified in some but not all areas and included literature describing self-determination and participation in leisure activities for those with mild intellectual disability. However, significant gaps were found particularly for those with severe intellectual disability. CONCLUSIONS: The ICF is a useful tool in framing a review of transition literature for young people with intellectual disability due to the complexity and multi-faceted nature of transition. The important influence of environmental factors including family systems, post-school services and access to transport were highlighted as having considerable impacts on transition outcomes.

ABSTRACT

BACKGROUND: This study was designed to examine basal and stress-induced levels of the neuroactive progesterone metabolite, allopregnanolone, in women with premenstrual dysphoric disorder (PMDD) and healthy control subjects. Also, because evidence suggests that allopregnanolone negatively modulates the hypothalamic-pituitary-adrenal axis, plasma cortisol levels were examined. An additional goal was to investigate the relationship between premenstrual symptom severity and luteal phase allopregnanolone levels. METHODS: Twenty-four women meeting prospective criteria for PMDD were compared with 12 controls during both the follicular and luteal phases of confirmed ovulatory cycles, counterbalancing phase at first testing. Plasma allopregnanolone and cortisol were sampled after an extended baseline period and again 17 min following the onset of mental stress. Owing to low follicular phase allopregnanolone levels, only luteal phase allopregnanolone and cortisol were analyzed. RESULTS: During the luteal phase, PMDD women had significantly greater allopregnanolone levels, coupled with significantly lower cortisol levels, during both baseline and mental stress. Moreover, significantly more controls (83%) showed the expected stress-induced increases in allopregnanolone compared with PMDD women (42%). Premenstrual dysphoric disorder women also exhibited a significantly greater allopregnanolone/progesterone ratio than control subjects, suggesting alterations in the metabolic pathways involved in the conversion of progesterone to allopregnanolone. Finally, PMDD women with greater levels of premenstrual anxiety and irritability had significantly reduced allopregnanolone levels in the luteal phase relative to less symptomatic PMDD women. No relationship between symptom severity and allopregnanolone was observed in controls. CONCLUSIONS: These results suggest dysregulation of allopregnanolone mechanisms in PMDD and that continued investigations into a potential pathophysiologic role of allopregnanolone in PMDD are warranted.

ABSTRACT

OBJECTIVE: Our aim was to compare the effects of transdermal versus oral estrogens on vascular resistance index, mean arterial pressure, serum lipid concentrations, norepinephrine, and left ventricular structure. STUDY DESIGN: Ten postmenopausal women received transdermal estradiol (0.05 mg/d) plus cyclic oral progesterone for 6 months. Responses were compared with those of 23 women receiving oral conjugated estrogens (0.625 mg/d) plus cyclic progesterone and with those of 9 subjects receiving placebo in a concurrent randomized trial. We assessed the vascular resistance index and the mean arterial pressure at rest and during behavioral stressors. RESULTS: Oral and transdermal estrogen significantly decreased the vascular resistance index, mean arterial pressure, norepinephrine, and total and low-density lipoprotein cholesterol to a similar extent. Changes in the vascular resistance index and mean arterial pressure were equally evident at rest and during stress. Although both treatments reduced left ventricular mass (-4% to -6%) and relative wall thickness (-3% to -5%), these changes were not statistically significant. CONCLUSIONS: Equivalent reductions in vascular resistance index, norepinephrine, mean arterial pressure, and cholesterol were observed with transdermal and oral estrogens. Future studies comparing novel hormone regimens with oral hormone replacement therapy should include multiple risk markers to allow better assessment of their potential impact on coronary artery health.

ABSTRACT

OBJECTIVE: To determine the effect of low-dose esterified estrogen on hemodynamic responses at rest and during stress in postmenopausal women, and to compare the changes with those seen with conjugated equine estrogen. DESIGN: Open-label study of esterified estrogen compared with a double-blind, placebo-controlled investigation of conjugated equine estrogen. SETTING: Healthy volunteers in an academic research environment. PATIENT(S): Postmenopausal women with normal endometrium, not currently using hormones. INTERVENTION(S): Cardiovascular parameters at rest and in response to stressors were assessed in 11 postmenopausal women before and 6 months after receiving 0.3 mg esterified estrogen. Responses were compared with 42 postmenopausal women randomized to 0.625 mg conjugated equine estrogen or placebo. MAIN OUTCOME MEASURE(S): Changes in mean arterial pressure (MAP) and vascular resistance index from before to after treatment. RESULT(S): At rest, MAP increased 3.3 +/- 1.5 mm Hg (+/-SD) in the placebo group, while declining 2.3 +/- 1.5 mm Hg and 4.8 +/- 1.4 mm Hg, respectively, in the esterified estrogen and conjugated equine estrogen groups after treatment. During mental stressors, MAP dropped significantly in both treatment groups. At rest and during mental stressors, vascular resistance index decreased with estrogen treatment. CONCLUSION(S): Low-dose esterified estrogen improved hemodynamic patterns similar to standard doses of conjugated equine estrogen in postmenopausal women.

ABSTRACT

BACKGROUND: Postmenopausal estrogen replacement, with or without progestins, has been related to lower cardiovascular risks. OBJECTIVE: We investigated whether the actions of estrogen on vascular resistance contribute to this cardioprotective effect. DESIGN AND METHODS: In a 6-month double-blind study, pre- and post-treatment blood pressure, cardiac index, total vascular resistance index and plasma catecholamine responses during baseline and mental stressors were compared in 69 women (including 19 with mild hypertension but no history of heart disease). Women were randomized to receive either conjugated estrogens alone, estrogens plus medroxyprogesterone, or placebo. RESULTS: Both groups on active hormone replacement showed similar decreases in vascular resistance and modest blood pressure reductions, which differed from the unchanged responses of those on placebo (P< 0.05) after 3 and 6 months of treatment. Hypertensive women showed greater reductions in vascular resistance than normotensives (P< 0.05) and their blood pressure reductions tended to be larger. Women receiving hormone replacement showed increased stroke volume and cardiac index at 6 months, particularly among hypertensives and those receiving medroxyprogesterone (P < 0.05). Hormone replacement was also related to decreases in plasma norepinephrine. Finally, in 33 women receiving hormone replacement, significant 5 and 3% decreases in echocardiographic measures of left ventricular mass index and relative wall thickness were evident at 6 months (P < 0.05), while 20 placebo-treated women showed no reliable echocardiographic improvements (P= NS). CONCLUSIONS: These findings suggest that estrogen-mediated reductions in hemodynamic load on the heart may contribute to the reduced risk of cardiovascular events in relatively healthy postmenopausal women who use hormone replacement.

ABSTRACT

We investigated the relationship of pessimistic attributional style (specifically, stable attributions for negative events) and socioeconomic status (SES) to cardiovascular and catecholamine profiles in a biracial sample of 37 postmenopausal women (aged 39-64 years) not taking hormone replacement therapy (HRT). Blood pressure (BP) variation in response to the demands of daily life was assessed by 24-hour ambulatory monitoring on a typical workday. Subjects were classified into groups by stable pessimistic attributions (high vs. low pessimism) and by SES (high vs. low). Significant SES x pessimism interactions were found. Low SES/high pessimism women demonstrated higher systolic BP (SBP) during the day, evening, and sleep periods of 24-hour ambulatory monitoring compared with the other three groups. A greater proportion of this group was in the hypertensive range (> or = 140/90 mm Hg) compared with the other groups (57% vs. 8%-29%). Low SES/high pessimism women also reported reduced available social support compared with the other three groups.

ABSTRACT

With use of a randomized, placebo-controlled trial, 62 healthy, postmenopausal smokers and nonsmokers were tested for resting and stress-induced hemodynamic variables before and after 6 months of treatment with either oral hormone replacement therapy or placebo. Smokers had significantly less reduction in both resting and stress-induced vascular resistance and blood pressure after treatment with oral hormone replacement therapy than nonsmokers.

ABSTRACT

OBJECTIVE: Cardiovascular, neuroendocrine, and psychosocial profiles were investigated in women with eating disorder tendencies, but who had never met clinical criteria for an eating disorder, and in healthy controls. METHODS: Twenty-six women who scored in the highest distribution of the Eating Disorder Inventory bulimia subscale (HEDI women) and 27 women who scored in the lowest distribution (LEDI women) completed psychosocial questionnaires, underwent a speech reactivity task for measures of blood pressure and heart rate reactivity, and also underwent 24-hour ambulatory blood pressure monitoring and urinary neuroendocrine collection. RESULTS: The HEDI women exhibited increased blood pressure and heart rate reactivity to the speech task and increased 24-hour urinary cortisol, but decreased 24-hour urinary norepinephrine compared with LEDI women. There were no overall group differences in 24-hour ambulatory blood pressure levels, but negative mood and tension were associated with greater systolic blood pressures for all women. Finally, HEDI women reported greater depressive symptoms and anxiety, lower self-esteem and sense of mastery, less social support, poor coping skills, and greater emotional impact of daily stressors relative to LEDI women. CONCLUSIONS: These results indicate that the same pattern of neuroendocrine and psychosocial profiles seen in prior studies of bulimia nervosa are also present in women with eating disorder tendencies.

ABSTRACT

OBJECTIVE: To investigate the effects of smoking and oral contraceptive (OC) formulation on hemodynamic responses to stress in women. METHODS: Twenty-three smokers and 23 nonsmokers taking different OC formulations (ie, containing higher or lower androgenic progesterones) were tested for cardiovascular reactivity during mathematic, speech preparation, speech, and cold pressor stress. RESULTS: During mental stress, smokers, regardless of OC formulation, had lower systolic blood pressure (BP) (eg, 10.2 versus 15.1 mmHg, P < .05), heart rate (eg, 7.5 versus 15.0 beats per minute, P < .01), and cardiac index reactivity (eg, 0.08 versus 0.48 L/minute/M2, P < .01) but greater vascular resistance index responses (eg, 115.6 versus -51.9 dyne-sec x cm(-5) x M2, P < .05). Women who took higher androgen OCs, regardless of smoking status, showed greater vascular resistance index increases during speech stress than those who took lower androgen OCs (215.8 versus 9.4 dyne-sec x cm(-5) x M2, P < .05). Smokers who took more androgenic OCs had greater systolic BP responses to speech preparation compared with nonsmokers who took the same OCs (12.1 versus 6.1 mmHg, P < .05), and smokers who took lower androgen OCs (12.1 versus 4.4 mmHg, P < .05). Least-squares means examination found that smokers who took higher androgen OCs had greater vascular resistance index increases to all mental stressors than nonsmokers who took lower androgen OCs. CONCLUSION: Higher androgen OCs might be linked to greater vascular and BP increases during stress, especially in smokers. Given that increased vascular resistance and BP contribute to cardiovascular mortality, those results suggest that androgenic profiles of synthetic progesterones might be an important consideration in OC choice.

ABSTRACT

High cardiovascular responsivity to stressors has not consistently improved prediction of later blood pressure increases beyond the predictive effects of baseline pressure. Animal models suggest that genetic susceptibility to hypertension and frequent stress exposure are important modulating factors in stress-related hypertension. Thus in 103 men originally tested at age 18 to 22 years and reassessed 10 years later, interactive effects of genetic susceptibility (defined as 1 or more hypertensive parents) with high stress responsivity (defined as top 25% on the basis of blood pressure and cardiac responses during both reaction time and cold pressor tasks) were examined in relation to follow-up systolic and diastolic levels and to change in blood pressure status from normal (diastolic<80 mm Hg) to marginally elevated (diastolic 85 to 95 mm Hg). Men with the combination of high stress response and hypertensive parents demonstrated higher systolic (P<0.05) and diastolic levels (P<0.05) at follow-up, and they showed a 7-fold increase (7.5, 95% confidence intervals 2.3, 24.3; P<0.001) in relative risk of change in blood pressure status versus men with no family history and a 3-fold increase (3.8, confidence intervals 1.5, 9.6; P<0.004) versus less stress-responsive men who also had hypertensive parents. In 65 men who also provided ratings of daily stress, family historyxstress responsivityxdaily stress interactions were significant in predicting follow-up systolic and diastolic levels (P<0.006 and 0.03, respectively), with highest pressure levels seen when high life stress was reported by high stress responders and/or men with hypertensive parents. In conclusion, results suggest that stress responsivity as a long-term predictor is modulated by both genetic and environmental factors.

ABSTRACT

Using a randomized, placebo-controlled design, this study assessed the effects of estrogen alone (ES) or in combination with cyclic progesterone (EP) on daily ratings of mood and physical symptoms before and after 6 months of daily hormone treatment. Fifty-four postmenopausal women were recruited from the community at large and specifically selected as being asymptomatic at the time of enrollment and without significant psychiatric history. Ratings were obtained every day for 30 days prior to treatment and again every day during the last 30 days of treatment. Results revealed that when compared with pretreatment levels, women randomized to EP (n = 16) exhibited statistically significant increases in daily depression, cramping, and breast tenderness and a marginally significant increase in daily anxiety. However, these increases were mild, not clinically significant, and did not interfere with normal functioning. Women randomized to ES (n = 20) showed no significant change in daily mood measures, although they did experience an increase in breast tenderness with estrogen. A significant placebo (n = 18) effect was observed, as there was a reliable reduction in daily irritability ratings (p < 0.05) with placebo. These findings suggest that for most postmenopausal women, the use of hormones will not be associated with clinically significant changes in mood or physical symptoms, which weighs favorably into the cost-benefit ratio for women considering hormone replacement therapy.
