Abstract

Background: Classroom-based physical activity interventions have demonstrated positive effects in reducing sedentary behaviour among school children. However, this is an understudied area, especially in low- and middle-income countries such as Sri Lanka. This study aims to explore teachers' opportunity, capability and motivation relating to the implementation of an in-classroom physical activity breaks programme. Methods: Twenty-seven teachers were recruited through snowball sampling and participated in semi-structured telephone interviews from early-January to the mid-June 2022. The Capability, Opportunity, and Motivation Behaviour (COM-B) model was used to guide and deductively thematic analyse the interviews. Results: 21 out of the recruited teachers responded to the full study. The mean age of respondents was 39.24 years old ranging from 27 years to 53 years. Teaching experience of the respondents ranged from three to 37 years, and 57% were female. Three teachers had a degree with a teacher training diploma, while others were having General Certificate of Education in Advanced Level with a teacher training diploma as the highest education qualification. Capability factors such as age, dress code, mask wearing, knowledge, skills and workload of the teachers were identified as important factors in implementing a physical activity breaks intervention in a Sri Lankan classroom setting. Classroom space, facilities, student backgrounds and safety were identified as opportunity factors. Obtaining policy level decisions to implement the activity breaks and managing the time of the activities to reduce time lost in education time were identified as motivational factors. Conclusion: During the intervention development phase, implementation facilitators and barriers must be considered carefully. Behaviour change techniques can be utilised to address the identified COM-B factors to ensure a good implementation of the intervention. [ABSTRACT FROM AUTHOR]

Abstract

BackgroundMany women with hyperglycaemia in pregnancy do not receive care during and after pregnancy according to standards recommended in international guidelines. The burden of hyperglycaemia in pregnancy falls disproportionately upon Indigenous peoples worldwide, including Aboriginal and Torres Strait Islander women in Australia. The remote and regional Australian context poses additional barriers to delivering healthcare, including high staff turnover and a socially disadvantaged population with a high prevalence of diabetes.MethodsA complex health systems intervention to improve care for women during and after a pregnancy complicated by hyperglycaemia will be implemented in remote and regional Australia (the Northern Territory and Far North Queensland). The Theoretical Domains Framework was used during formative work with stakeholders to identify intervention components: (1) increasing workforce capacity, skills and knowledge and improving health literacy of health professionals and women; (2) improving access to healthcare through culturally and clinically appropriate pathways; (3) improving information management and communication; (4) enhancing policies and guidelines; (5) embedding use of a clinical register as a quality improvement tool. The intervention will be evaluated utilising the RE-AIM framework at two timepoints: firstly, a qualitative interim evaluation involving interviews with stakeholders (health professionals, champions and project implementers); and subsequently a mixed-methods final evaluation of outcomes and processes: interviews with stakeholders; survey of health professionals; an audit of electronic health records and clinical register; and a review of operational documents. Outcome measures include changes between pre- and post-intervention in: proportion of high risk women receiving recommended glucose screening in early pregnancy; diabetes-related birth outcomes; proportion of women receiving recommended postpartum care including glucose testing; health practitioner confidence in providing care, knowledge and use of relevant guidelines and referral pathways, and perception of care coordination and communication systems; changes to health systems including referral pathways and clinical guidelines.DiscussionThis study will provide insights into the impact of health systems changes in improving care for women with hyperglycaemia during and after pregnancy in a challenging setting. It will also provide detailed information on process measures in the implementation of such health system changes.

Abstract

12 p., Background: The imperative to improve global health has prompted transnational research partnerships to investigate common health issues on a larger scale. The Global Alliance for Chronic Diseases (GACD) is an alliance of national research funding agencies. To enhance research funded by GACD members, this study aimed to standardise data collection methods across the 15 GACD hypertension research teams and evaluate the uptake of these standardised measurements. Furthermore we describe concerns and difficulties associated with the data harmonisation process highlighted and debated during annual meetings of the GACD funded investigators. With these concerns and issues in mind, a working group comprising representatives from the 15 studies iteratively identified and proposed a set of common measures for inclusion in each of the teams’ data collection plans. One year later all teams were asked which consensus measures had been implemented. Results: Important issues were identified during the data harmonisation process relating to data ownership, sharing methodologies and ethical concerns. Measures were assessed across eight domains; demographic; dietary; clinical and anthropometric; medical history; hypertension knowledge; physical activity; behavioural (smoking and alcohol); and biochemical domains. Identifying validated measures relevant across a variety of settings presented some difficulties. The resulting GACD hypertension data dictionary comprises 67 consensus measures. Of the 14 responding teams, only two teams were including more than 50 consensus variables, five teams were including between 25 and 50 consensus variables and four teams were including between 6 and 24 consensus variables, one team did not provide details of the variables collected and two teams did not include any of the consensus variables as the project had already commenced or the measures were not relevant to their study. Conclusions: Deriving consensus measures across diverse research projects and contexts was challenging. The major barrier to their implementation was related to the time taken to develop and present these measures. Inclusion of consensus measures into future funding announcements would facilitate researchers integrating these measures within application protocols. We suggest that adoption of consensus measures developed here, across the field of hypertension, would help advance the science in this area, allowing for more comparable data sets and generalizable inferences.

Abstract

Cell surface mucins configure the cell surface by presenting extended protein backbones that are heavily O-glycosylated. The glycopeptide structures establish physicochemical properties at the cell surface that enable and block the formation of biologically important molecular complexes. Some mucins, such as MUC1, associate with receptor tyrosine kinases and other cell surface receptors, and engage in signal transduction in order to communicate information regarding conditions at the cell surface to the nucleus. In that context, the MUC1 cytoplasmic tail (MUC1CT) receives phosphorylation signals from receptor tyrosine kinases and serine/threonine kinases, which enables its association with different signaling complexes that conduct these signals to the nucleus and perhaps other subcellular organelles. We have detected the MUC1CT at promoters of over 500 genes, in association with several different transcription factors, and have shown that promoter occupancy can vary under different growth factor conditions. However, the full biochemical nature of the nuclear forms of MUC1 and its function at these promoter regions remain undefined. I will present evidence that nuclear forms of the MUC1CT include extracellular and cytoplasmic tail domains. In addition, I will discuss evidence for a hypothesis that the MUC1CT possesses a novel catalytic function that enables remodeling of the transcription factor occupancy of promoters, and thereby engages in regulation of gene expression.

Abstract

The demographics of computer-mediated communication (CMC) users have changed considerably over the last twenty years. Whereas in the 1980's it was largely academics, and computing and IT professionals that used CMC such as email, the 1990's saw an increase in novice users, which coincided with the growth of the WWW, the viability of Internet access in homes, and with the proliferation of new CMC technologies. This shift in user demographics has resulted in a higher prevalence of known problems in CMC, such as misunderstandings and aggressive behaviour. Interestingly, the design of the user interface (UI) of CMC applications can assist in overcoming these problems. This paper discusses the merits of a user-centred design (UCD) approach to the design of CMC applications. It presents an initial study carried out to gain insights from four distinct user groups, and discusses its implications in improving the quality of CMC for users. [ABSTRACT FROM AUTHOR]

Abstract

Computer-mediated communication (CMC) is fundamentally different to face-to-face (FTF) communication. The low bandwidth of CMC filters out important social and contextual cues, which results in behaviour in users that is different to FTF communication. There are a number of social psychological theories that attempt to explain why reduced social cues in CMC affect behaviour. This work attempts to apply this knowledge to the design of the user interface (UI) of CMC applications. Key aspects of communication are identified and electronically represented in the UI of a prototype CMC application. Two evaluation studies are then carried out, using the Tropical Island Dilemma and the Map Task, to determine if the identified features have an effect on one-to-one distributed communication. Finally, a set of guidelines is presented for the design of CMC applications, which are derived from the findings of this work. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: Fewer than half of all people at highest risk of a cardiovascular event are receiving and adhering to best practice recommendations to lower their risk. In this project, we examine the role of an e-health-assisted consumer-focused strategy as a means of overcoming these gaps between evidence and practice. Consumer Navigation of Electronic Cardiovascular Tools (CONNECT) aims to test whether a consumer-focused e-health strategy provided to Aboriginal and Torres Strait Islander and non-indigenous adults, recruited through primary care, at moderate-to-high risk of a cardiovascular disease event will improve risk factor control when compared with usual care. Methods and analysis: Randomised controlled trial of 2000 participants with an average of 18 months of follow-up to evaluate the effectiveness of an integrated consumer-directed e-health portal on cardiovascular risk compared with usual care in patients with cardiovascular disease or who are at moderate-to-high cardiovascular disease risk. The trial will be augmented by formal economic and process evaluations to assess acceptability, equity and cost-effectiveness of the intervention. The intervention group will participate in a consumer-directed e-health strategy for cardiovascular risk management. The programme is electronically integrated with the primary care provider's software and will include interactive smart phone and Internet platforms. The primary outcome is a composite endpoint of the proportion of people meeting the Australian guideline-recommended blood pressure (BP) and cholesterol targets. Secondary outcomes include change in mean BP and fasting cholesterol levels, proportion meeting BP and cholesterol targets separately, self-efficacy, health literacy, self-reported point prevalence abstinence in smoking, body mass index and waist circumference, self-reported physical activity and self-reported medication adherence. Ethics and dissemination: Primary ethics approval was received from the University of Sydney Human Research Ethics Committee and the Aboriginal Health and Medical Research Council. Results will be disseminated via the usual scientific forums including peer-reviewed publications and presentations at international conferences Clinical Trials registration number: ACTRN12613000715774.

Abstract

Sudden cardiac death (SCD) can be caused by a number of reasons. Previous works have identified the genetic causes, such as alterations in the DNA sequence, for many of these diseases. We hypothesize that some patients may show genomic imbalances and changes in the gene copy number leading to genetic instability. To clarify this, we analysed DNA samples from SCD victims using comparative genomic hybridization (CGH), a molecular cytogenetic technique that permits the genome-wide screening of chromosomal imbalances, and telomere length measurement. DNA derived from peripheral blood and heart tissue of 14 SCD cases and six apparently healthy control individuals were subjected to CGH analysis. Telomere length measurements were done by the Southern blotting method. Eight out of 14 SCD cases exhibited changes in DNA/gene copy number. CGH analysis showed variation in the gene copy number of some of the genes associated with potassium (KCNAB1, KCNH2, and KCNA4) and calcium (RyR2, ATP2A2) ions which are involved in maintaining the ionic balance of the heart. Alterations in TERC and TERT genes were also detected in SCD victims. In nine SCD victims shorter telomeres were detected. This might have resulted from excessive cellular proliferation and/or oxidative stress in these individuals. Copy number changes observed and telomere shortening detected in SCD cases would possibly explain at least some of the causes of SCD at early ages in humans. Identification of biomarkers of SCD is of great importance and thus the present study will facilitate the identification of some of the biomarkers. Copyright © 2008 S.

Abstract

The article discusses the two experiments designed to identify some of the factors which contribute to effective text-based computer mediated communication for people with disabilities. Implications of how people use text-based CMC to express emotion and personality will be discussed. Strategies that need to be developed to overcome problems caused by a lack of physical information when transmitting emotions and personality are identified.

Abstract

Rhabdomyolysis results from acute damage of the skeletal muscle brought on by various conditions of which hypokalemia is a recognized, but less common condition. Although primary aldosteronism may cause severe hypokalemia leading to rhabdomyolysis, the patients may have potassium levels within the normal range on routine biochemistry. In addition, hypokalemia may be triggered by initiation of diuretic therapy for control of hypertension. Here, we describe a patient with an aldosterone secreting adrenal adenoma, who presented with acute rhabdomyolysis secondary to severe hypokalemia triggered by initiation of diuretic therapy.

Abstract

A user centred design (UCD) approach in the development lifecycle of a product increases usability and user satisfaction. Emphasis is placed on early and continual focus on users and on early and continual user testing. This research adopts a UCD approach for the development of text-based computer mediated communication (CMC) software. It uses the concept of ordinary and extraordinary human-computer interaction to help define the requirements specification of the software. Four groups including Deaf and hearing-impaired participants took part in the requirements gathering study and their comments and feedback was used in the requirements specification.
