Aetiological overlap between anxiety and attention deficit hyperactivity symptom dimensions in adolescence

Background: Anxiety and attention deficit hyperactivity (ADH) problems are common in adolescence, often co-occur, and are characterised by high heterogeneity in their phenotypic expressions. Although it is known that anxiety and ADH problems correlate, the relationships between subtypes of anxiety and ADH problems have been scarcely investigated. Methods: Using a large population sample of adolescent twins and siblings we explored the phenotypic and aetiological association between anxiety subtypes (panic/agoraphobia, separation anxiety, social anxiety, physical injury fears, obsessive-compulsive symptoms and generalised anxiety) and the two ADH dimensions (attention problems and hyperactivity/impulsivity). Both phenotypes were assessed using self-report questionnaires. Results: The association between ADH problems and anxiety could be entirely attributed to attention problems, not hyperactivity/impulsivity. Most of the correlations between anxiety subtypes and attention problems showed an approximately equal role of genetic and non-shared environmental factors. Conclusions: The high heterogeneity within anxiety and ADH problems should be taken into account in order to better understand comorbidity between them

Accommodation needs for carers of and adults with intellectual disability in regional Australia: Their hopes for and perceptions of the future

Introduction: This article provides an in-depth investigation of the accommodation circumstances of a population of aging adults with intellectual disability living at home with parents or in supported accommodation in an Australian regional centre. Given the ageing of both the carer and adult population with intellectual disability our research explored the accommodation needs and perceptions of future lifestyle issues from the perspective of both the carers and the adults with intellectual disability. This study aimed to describe these accommodation circumstances related to a regional/rural location and did not make direct comparisons with urban/metropolitan situations. Methods: A mixed methods approach, specifically an explanatory design, participant selection model was utilised for the overall study. This article reports on the qualitative study consisting of data from both free response open-ended survey questions and semi-structured interviews with selected adults with intellectual disability and their carers. This study explored and described participants’ experiences and perceptions regarding their accommodation needs and future lifestyle issues. A purposive sampling technique was used to identify a representative sample of participants for interviews. The interview questions were guided by the results of the quantitative first study phase. Data were analysed by content analysis for major themes emerging from the interview and free response survey data. Results: A total of 146 carers (mean age 61.5 years; range 40–91 years) and 156 adults with intellectual disability (mean age 37.2 years; range 18–79 years) participated in the study. Data saturation was reached after 10 interviews were undertaken with carers (mean age 60 years) and 10 with adults with intellectual disability (no age criteria applied). Six major themes were identified: ageing, family issues, living at home, living away from home, government support and funding, and future needs. The perceptions and views of both adults with intellectual disability and their carers around these major themes are reported and discussed. Conclusions: This study indicates that there is a lack of suitable, available, supported accommodation for people aged 18 years and older with intellectual disability in this Australian regional centre. Consequently, aging parents caring at home have little choice but to continue in their caring role. For those caring away from home, existing services are decreasingly seen as fitting the ideal life they want for the person with intellectual disability for whom they care. The told experiences, perceptions and views of older carers of and adults with intellectual disability have highlighted their increasing vulnerability to the ‘disability system’. The findings suggest that government and disability services must acknowledge the changing needs of people with intellectual disability in connection with their advancing age and the urgency of increasing care needs due to the advancing age of their carer/s. The overwhelming feeling is that the carer’s voice will only be heard when the situation reaches crisis point. For many carers and their families this has already occurred

Role of micronutrients in HIV infection

More than 60% of the estimated 40 million persons with HIV/AIDS worldwide live in sub-Saharan Africa, where poverty, social insecurity, food shortages and malnutrition are major problems.1 In children under the age of 5 years, who live in developing countries, malnutrition has been associated with 50% of the 10.8 million deaths mainly caused by neonatal disorders, diarrhoea, pneumonia, malaria and HIV/AIDS.2 Likewise micronutrient deficiencies are widespread and are associated with increased morbidity and mortality particularly in relation to infectious diseases.3 This review focuss on the interaction between micronutrients and HIV/AIDS and discusses recent research findings that may have important public health implications in terms of the case management of persons with HIV/AIDS Southern African Journal of HIV Medicine Vol. 6 (2) 2005: pp. 18-2

A decade of Australian Rural Clinical School graduates: Where are they and why?

Introduction: The Australian Rural Clinical School (RCS) initiative has been addressing the rural medical workforce shortage at the medical education level for over a decade. A major expectation of this initiative is that it will improve rural medical workforce recruitment and subsequent retention through a rurally based undergraduate clinical training experience. The longitudinal nature of these workforce initiatives means that definitive evidence of its impact on the shortage of rural doctors is yet to be provided; however, to date cross-sectional studies are accumulating a measure of efficacy for these initiatives by monitoring early career factors such as internship location choice and speciality choice of RCS graduates. This article reports on a study in one RCS that is monitoring the impact of rural undergraduate clinical training on trends in workforce participation patterns of its graduates as long as 9 years in the workforce. Career location and speciality choice are reported as well as perspectives on early career intentions and the reality of making career and life decisions as a doctor in the medical workforce

Structural role of the tyrosine residues of cytochrome c

The tertiary structures of horse, tuna, Neurospora crassa, horse [Hse65,Leu67]- and horse [Hse65,Leu74]-cytochromes c were studied with high-resolution 1H n.m.r. spectroscopy. The amino acid sequences of these proteins differ at position 46, which is occupied by phenylalanine in the horse proteins but by tyrosine in the remaining two, and at positions 67, 74 and 97, which are all occupied by tyrosine residues in horse and tuna cytochrome c but in the other proteins are substituted by phenylalanine or leucine, though there is only one such substitution per protein. The various aromatic-amino-acid substitutions do not seriously affect the protein structure

Clinical and behavioural features of SYNGAP1-related intellectual disability: a parent and caregiver description

BACKGROUND: SYNGAP1-related intellectual disability (ID) is a recently described neurodevelopmental disorder that is caused by pathogenic variation in the SYNGAP1 gene. To date, the behavioural characteristics of this disorder have mainly been highlighted via the prevalence of existing diagnoses in case series. We set out to detail the behavioural features of this disorder by undertaking interviews with those who have a child with SYNGAP1-related ID to allow them to describe their child’s behaviour. METHODS: We conducted 27 semi-structured interviews with parents and caregivers which covered basic information (e.g., age, gender), family history, perinatal history, past medical history, developmental history, epilepsy, behavioural history, and a general description of their child’s behaviour. RESULTS: Using a mixed quantitative and qualitative approach, the responses from the parents indicated that those with SYNGAP1-related ID showed high rates of autism spectrum disorder (52%), difficulties with fine and gross motor skills, delays in language development, and a high prevalence of epilepsy (70%). A qualitative analysis highlighted their general behaviour affected the themes of daily living skills, distress-related behaviours, emotional regulation, difficulties with change, a lack of danger awareness, and sensory differences. Sensory features described involved auditory, visual, tactile, gustatory, and proprioceptive themes. CONCLUSIONS: Our findings and behavioural descriptions provide important insights as well as implications for the diagnosis and care of those with SYNGAP1-related ID.

Reciprocal links between anxiety sensitivity and obsessive-compulsive symptoms in youth: a longitudinal twin study

Background: Anxiety sensitivity, the tendency to fear the symptoms of anxiety, is a key risk factor for the development anxiety disorders. Although obsessive-compulsive disorder was previously classified as an anxiety disorder, the prospective relationship between anxiety sensitivity and obsessive-compulsive symptoms (OCS) has been largely overlooked. Furthermore, a lack of genetically-informative studies means the aetiology of the link between anxiety sensitivity and OCS remains unclear. Methods: Adolescent twins and siblings (N=1,579) from the G1219 study completed self-report questionnaires two years apart assessing anxiety sensitivity, OCS, anxiety and depression. Linear regression models tested prospective associations between anxiety sensitivity and OCS, with and without adjustment for anxiety and depressive symptoms. A phenotypic cross-lagged model assessed bidirectional influences between anxiety sensitivity and OCS over time, and a genetic version of this model examined the aetiology of these associations. Results: Anxiety sensitivity was prospectively associated with changes in OCS, even after controlling for comorbid anxiety and depressive symptoms. The longitudinal relationship between anxiety sensitivity and OCS was bidirectional, and these associations were predominantly accounted for by non-shared environmental influences. Conclusions: Our findings are consistent with the notion that anxiety sensitivity is a risk factor for OCS during adolescence, but also suggest that experiencing OCS confers risk for heightened anxiety sensitivity. The reciprocal links between OCS and anxiety sensitivity over time are likely to be largely mediated by non-shared environmental experiences, as opposed to common genes. Our findings raise the possibility that interventions aimed at ameliorating anxiety sensitivity could reduce risk for OCS, and vice versa
