Seclusion use with children and adolescents: an Australian experience

Objective: To summarize the current state of knowledge on the use of seclusion and restraint with children and adolescents and to report the findings of an exploratory study to identify factors that place a child or adolescent at increased risk of seclusion during their admission. Method: Literature searches were undertaken on MEDLINE, CINAHL and PsycINFO databases. Articles were identified that focused specifically on seclusion and restraint use with children and adolescents or contained material significant to this population. The study reports findings from a retrospective review of patient charts, seclusion registers and staffing from an Australian acute inpatient facility. Results: The data available in regard to seclusion use in this population is limited and flawed. Further research is needed on the use and outcomes of seclusion and restraint and on alternative measures in the containment of dangerousness. Both the literature and this study find that patients with certain factors are at increased risk of being secluded during an inpatient stay. These factors include being male, diagnoses of disruptive behaviour disorder and a previous history of physical abuse. Staffing factors did not show a relationship to the use of seclusion. Conclusions: There are patient factors that predict increased risk of seclusion; these factors and their interrelationships require further elucidation. Further research is also needed on the outcomes, both positive and negative, of seclusion use and of alternatives to seclusion.

Theory-of-mind development in oral deaf children with cochlear implants or conventional hearing aids

Background: In the context of the established finding that theory-of-mind (ToM) growth is seriously delayed in late-signing deaf children, and some evidence of equivalent delays in those learning speech with conventional hearing aids, this study's novel contribution was to explore ToM development in deaf children with cochlear implants. Implants can substantially boost auditory acuity and rates of language growth. Despite the implant, there are often problems socialising with hearing peers and some language difficulties, lending special theoretical interest to the present comparative design. Methods: A total of 52 children aged 4 to 12 years took a battery of false belief tests of ToM. There were 26 oral deaf children, half with implants and half with hearing aids, evenly divided between oral-only versus sign-plus-oral schools. Comparison groups of age-matched high-functioning children with autism and younger hearing children were also included. Results: No significant ToM differences emerged between deaf children with implants and those with hearing aids, nor between those in oral-only versus sign-plus-oral schools. Nor did the deaf children perform any better on the ToM tasks than their age peers with autism. Hearing preschoolers scored significantly higher than all other groups. For the deaf and the autistic children, as well as the preschoolers, rate of language development and verbal maturity significantly predicted variability in ToM, over and above chronological age. Conclusions: The finding that deaf children with cochlear implants are as delayed in ToM development as children with autism and their deaf peers with hearing aids or late sign language highlights the likely significance of peer interaction and early fluent communication with peers and family, whether in sign or in speech, in order to optimally facilitate the growth of social cognition and language.

Living on the ground research: Steps towards white women researching in collaboration with indigenous people

De Ishtar discusses ways in which Whites could develop research epistemologies and methodologies which responded to and reflected those being developed by Indigenous researchers across Australia and around the world. She details her own explorations in developing a methodology which enabled her to work in collaboration with a group of Indigenous women elders from Western Australia's Great Sandy Desert. She stresses that if collaborative research with Indigenous women is to be possible, White feminists must learn how to do research which is culturally unobtrusive, and that means taking responsibility for their own cultural practices, attitudes and values.

Morbidity due to Schistosoma mansoni: an epidemiological assessment of distended abdomen syndrome in Ugandan school children with observations before and 1-year after anthelminthic chemotherapy

The objectives of this study were to determine the prevalence and distribution of distended abdomens among Ugandan school children across a range of eco-epidemiological settings and to investigate the relationship between distended abdomens and helminth infections, in particular Schistosoma mansoni, before and 1-year after anthelminthic treatment. A cross-sectional survey was conducted on 4354 school children across eight districts, with a longitudinal 1-year follow-up of 2644 children (60.7%). On both occasions, parasitological, biometrical and clinical data were collected for each child. Baseline prevalence of S. mansoni and hookworms was 44.3% and 51.8%, respectively. Distended abdomens, defined as an abdominal circumference ratio (ACR) >1.05, were observed in 2.5% of the sampled children, several of whom presented with particularly severe distensions necessitating hospital referral. ACR scores were highly overdispersed between districts and schools. Multivariate regression analysis revealed that S. mansoni infection accounted for only a small fraction of ACR variation, suggesting that either single point prevalence and intensity measures failed to reflect this more chronically evolved morbidity and/or that other interacting factors were involved, e.g. malnutrition and malaria. At 1-year follow-up, ACR scores showed an overall trend of regression towards the mean, potentially indicative of amelioration following chemotherapy, but geographic overdispersion still remained. © 2006 Royal Society of Tropical Medicine and Hygiene.

Zinc and vitamin A supplementation in Indigenous Australian children hospitalised with lower respiratory tract infection: a randomised controlled trial

Objective: To evaluate the efficacy of supplementation with zinc and vitamin A in Indigenous children hospitalised with acute lower respiratory infection (ALRI). Design: Randomised controlled, 2-by-2 factorial trial of supplementation with zinc and vitamin A. Setting and participants: 187 Indigenous children aged < 11 years hospitalised with 215 ALRI episodes at Alice Springs Hospital (April 2001 to July 2002). Interventions: Vitamin A was administered on Days 1 and 5 of admission at a dose of 50 000 IU (infants under 12 months), or 100 000 IU; and zinc sulfate was administered daily for 5 days at a daily dose of 20 mg (infants under 12 months) or 40 mg. Main outcome measure: Time to clinical recovery from fever and tachypnoea, duration of hospitalisation, and readmission for ALRI within 120 days. Results: There was no clinical benefit of supplementation with vitamin A, zinc or the two combined, with no significant difference between zinc and no-zinc, vitamin A and no-vitamin A or zinc + vitamin A and placebo groups in time to resolution of fever or tachypnoea, or duration of hospitalisation. Instead, we found increased morbidity; children given zinc had increased risk of readmission for ALRI within 120 days (relative risk, 2.4; 95% CI, 1.003–6.1). Conclusion: This study does not support the use of vitamin A or zinc supplementation in the management of ALRI requiring hospitalisation in Indigenous children living in remote areas. Even in populations with high rates of ALRI and poor living conditions, vitamin A and zinc therapy may not be useful. The effect of supplementation may depend on the prevalence of deficiency of these micronutrients in the population.

The ethics of paying drug users who participate in research: a review and practical recommendations

THE PAYMENT OF RESEARCH PARTICIPANTS raises ethical and empirical questions that have special importance in addictions research involving drug-dependent participants. Despite a now large literature on human subjects payment, what is still needed is practical guidance for investigators and ethics committees. This paper reviews the literature on: current payment practices and guidelines; defining features of undue and due incentives and fair reimbursement; and the significance of risks and harms that may arise from paying drug using participants. We conclude that research payments are ethically acceptable in most circumstances of addictions research, but should be closely scrutinized in situations where these may exacerbate existing harms or create additional risks for participants and investigators. General principles, key questions and procedural options are highlighted for an applied approach to ethical research payments. Future research directions are identified.

Research with in-built replications:comment and further suggestions for replication research

This brief commentary on the paper Designing Research with In-built Differentiated Replication expands on concerns about a lack of replication research by focusing on three key questions of continuous importance: Why should researchers conduct more replication research? Why do so few researchers conduct replication studies? What can researchers do to add more studies? This paper identifies barriers preventing replication related to the scientific system, the replication researcher, and the initial research. Suggestions include publishing all papers electronically along with reviews; authors taking steps to encourage replications of their work; and editors inviting replications of important papers. The scientific community should establish a replication index as a measure of output quality. © 2012 Elsevier Inc.

Exploring quality of life in families of children living with and without a severe food allergy

This study aimed to explore the impact of food allergy on quality of life in children with food allergy and their primary caregivers, compared to a healthy non-food allergy comparison group. Food allergy children (n = 34) and control children (n = 15), aged 8–12, and their respective primary caregivers (n = 30/n = 13), completed generic quality of life scales (PedsQL™ and WHOQOLBREF) and were asked to take photographs and keep a diary about factors that they believed enhanced and/or limited their quality of life, over a one-week period. Questionnaire analysis showed that parents of children with food allergy had significantly lower quality of life in the social relationships domain and lower overall quality of life than the comparison parents. In contrast, children with food allergy had similar or higher quality of life scores compared to comparison children. Content analysis of photograph and diary data identified ten themes that influenced both child and parental quality of life. It was concluded that although food allergy influenced quality of life for some children, their parent's quality of life was hindered to a greater extent. The variability in findings highlights the importance of assessing quality of life in individual families, considering both children with allergies and their primary caregivers.

Tale of two studies:challenges in field research with low-literacy adult learners in a developed country

Efforts to address the problems of literacy are often focused on developing countries. However, functional illiteracy is a challenge encountered by up to 50% of adults in developed countries. In this paper we reflect on the challenges we faced in trying to design and study the use of a mobile application to support adult literacy with two user groups: adults enrolled in literacy classes and carpenters without a high school education enrolled in an essential skills program. We also elaborate on aspects of the evaluations that are specific to a marginalized, functionally illiterate, group in a developed country - aspects that are less frequently present in similar studies of mobile literacy support technologies in developing countries. We conclude with presenting the lessons learnt from our evaluations and the impact of the studies' specific challenges on the outcome and uptake of such mobile assistive technologies in providing practical support to low-literacy adults in conjunction with literacy and essential skills training.

Brief report:effects of sensory sensitivity and intolerance of uncertainty on anxiety in mothers of children with autism spectrum disorder

This study examined the relations between anxiety and individual characteristics of sensory sensitivity (SS) and intolerance of uncertainty (IU) in mothers of children with ASD. The mothers of 50 children completed the Hospital Anxiety and Depression Scale, the Highly Sensitive Person Scale and the IU Scale. Anxiety was associated with both SS and IU and IU was also associated with SS. Mediation analyses showed direct effects between anxiety and both IU and SS but a significant indirect effect was found only in the model in which IU mediated between SS. This is the first study to characterize the nature of the IU and SS interrelation in predicting levels of anxiety.

Trends in research on the possible effects of climate change concerning aquatic ecosystems with special emphasis on the modelling approach

Knowledge on the expected effects of climate change on aquatic ecosystems is defined by three ways. On the one hand, long-term observation in the field serves as a basis for the possible changes; on the other hand, the experimental approach may bring valuable pieces of information to the research field. The expected effects of climate change cannot be studied by empirical approach; rather mathematical models are useful tools for this purpose. Within this study, the main findings of field observations and their implications for future were summarized; moreover, the modelling approaches were discussed in a more detailed way. Some models try to describe the variation of physical parameters in a given aquatic habitat, thus our knowledge on their biota is confined to the findings based on our present observations. Others are destined for answering special issues related to the given water body. Complex ecosystem models are the keys of our better understanding of the possible effects of climate change. Basically, these models were not created for testing the influence of global warming, rather focused on the description of a complex system (e. g. a lake) involving environmental variables, nutrients. However, such models are capable of studying climatic changes as well by taking into consideration a large set of environmental variables. Mostly, the outputs are consistent with the assumptions based on the findings in the field. Since synthetized models are rather difficult to handle and require quite large series of data, the authors proposed a more simple modelling approach, which is capable of examining the effects of global warming. This approach includes weather dependent simulation modelling of the seasonal dynamics of aquatic organisms within a simplified framework.
