Digital technology and Australian teenagers: consumption, study and careers

In this report, detailed primary evidence regarding high school student use of ICT, perceptions of use of ICT at school, perceptions of ICT as a discipline, and motivations regarding career choices was generated. Australian teenagers have welcomed digital technologies into their daily lives with open arms. As one Year 12 girl said of her mobile phone, “I just like having it with me”. Although this thirst for technology consumption does not always translate into an interest in pursuing technology as a career, the need to encourage more young people to take up careers in Information and Communication Technology is a question of Australian national interest. Sustaining and increasing productivity in modern economies largely depends on the application of new technology, and current and projected labour force figures suggest we do not have sufficient graduates entering ICT jobs. This report details findings of a research study commissioned by the Australian Computer Society, conducted with 202 subjects aged 12-18 years at government and non-government high schools in the Australian Capital Territory in 2012. Findings indicate a range of student misperceptions about the study of ICT; some are related to gender; others to age; others to school ICSEA rank; or a combination of these. There is considerable scope, particularly in early high school, to take advantage of students’ interest in computers; to develop an interest in studying ICT; and to challenge misperceptions about ICT careers. A range of initiatives and interventions can be developed and implemented by professional bodies, educators and other stakeholders to target these opportunities

Mesenteric lymph nodes at the center of immune anatomy

The surface of the intestinal mucosa is constantly assaulted by food antigens and enormous numbers of commensal microbes and their products, which are sampled by dendritic cells (DCs). Recent work shows that the mesenteric lymph nodes (MLNs) are the key site for tolerance induction to food proteins and that they also act as a firewall to prevent live commensal intestinal bacteria from penetrating the systemic immune system

Practitioner perspectives on strategies to promote longer-term benefits of acupuncture or counselling for depression: a qualitative study

Background: Non-pharmacological interventions for depression may help patients manage their condition. Evidence from a recent large-scale trial (ACUDep) suggests that acupuncture and counselling can provide longer-term benefits for many patients with depression. This paper describes the strategies practitioners reported using to promote longer-term benefits for their patients. Methods: A qualitative sub-study of practitioners (acupuncturists and counsellors) embedded in a randomised controlled trial. Using topic guides, data was collected from telephone interviews and a focus group, altogether involving 19 counsellors and 17 acupuncturists. Data were audio recorded, transcribed verbatim and analysed using thematic content analysis. Results: For longer-term impact, both acupuncturists and counsellors encouraged insight into root causes of depression on an individual basis and saw small incremental changes as precursors to sustained benefit. Acupuncturists stressed the importance of addressing concurrent physical symptoms, for example helping patients relax or sleep better in order to be more receptive to change, and highlighted the importance of Chinese medicine theory-based lifestyle change for lasting benefit. Counsellors more often highlighted the importance of the therapeutic relationship, emphasising the need for careful “pacing” such that the process and tools employed were tailored and timed for each individual, depending on the “readiness” to change. Our data is limited to acupuncture practitioners using the principles of traditional Chinese medicine, and counsellors using a humanistic, non-directive and person-centred approach. Conclusions: Long-term change appears to be an important focus within the practices of both acupuncturists and counsellors. To achieve this, practitioners stressed the need for an individualised approach with a focus on root causes

Developing and validating a questionnaire for mortality follow-back studies on end-of-life care and decision-making in a resource-poor Caribbean country

Background Palliative and end-of-life care development is hindered by a lack of information about the circumstances surrounding dying in developing and resource-poor countries. Our aims were to develop and obtain face and content validity for a self-administered questionnaire on end-of-life care provision and medical decision-making for use in population-based surveys. Methods Modelled on validated questionnaires from research in developed countries, our questionnaire was adapted to the cultural sensitivity and medico-legal context of Trinidad and Tobago. Two sets of semi-structured face-to-face cognitive interviews were done with a sample of physicians, sampling was purposive. Phase 1 assessed interpretation of the questions, terminology and content of the questionnaire. Phase 2 was tested on a heterogeneous group of physicians to identify and fix problematic questions or recurring issues. Adjustments were made incrementally and re-tested in successive interviews. Results Eighteen physicians were interviewed nationwide. Adaptations to questionnaires used in developed countries included: addition of a definition of palliative care, change of sensitive words like expedited to influenced, adjustments to question formulations, follow-up questions and answer options on medications used were added, the sequence, title and layout were changed and instructions for completion were included at the beginning of the questionnaire. Conclusion A new instrument for assessing and documenting end-of-life care and circumstances of dying in a small, resource-poor Caribbean country was developed and validated, and can be readily used as a mortality follow-back instrument. Our methods and procedures of development can be applied as a guide for similar studies in other small developing countries

iRFP is a real time marker for transformation based assays in high content screening

Anchorage independent growth is one of the hallmarks of oncogenic transformation. Here we show that infrared fluorescent protein (iRFP) based assays allow accurate and unbiased determination of colony formation and anchorage independent growth over time. This protocol is particularly compatible with high throughput systems, in contrast to traditional methods which are often labor-intensive, subjective to bias and do not allow further analysis using the same cells. Transformation in a single layer soft agar assay could be documented as early as 2 to 3 days in a 96 well format, which can be easily combined with standard transfection, infection and compound screening setups to allow for high throughput screening to identify therapeutic targets

WHO consolidated guidelines on tuberculosis Module 2: Screening – Systematic screening for tuberculosis disease

Background Tuberculosis (TB) is a leading cause of death from a single infectious agent, despite being largely curable and preventable. In 2019 an estimated 2.9 million of the 10 million people who fell ill with TB were not diagnosed or reported to the World Health Organization. The Political Declaration adopted by the United Nations General Assembly in September 2018 commits, amongst others, to diagnosing and treating 40 million people with TB by 2022. In order to achieve this ambitious target, there is an urgent need to deploy strategies to improve diagnosis and initiation of care for people with TB. One of them is systematic screening for TB disease, which is included in the End TB Strategy as a central component of its first pillar to ensure early diagnosis for all with TB. To help facilitate the implementation of TB screening at the country level, WHO published guidelines on screening for TB in 2013. Since then, there have been important new studies evaluating the impact of screening interventions on both individual-level and community-level outcomes related to TB, as well as new research evaluating innovative tools for screening for TB among important populations at high risk for TB disease. Overview In view of these new developments and upon demand by countries for more guidance, WHO convened a Guideline Development Group (GDG) in 2020 to examine the evidence and prepare WHO consolidated guidelines on tuberculosis. Module 2: Screening - Systematic screening for tuberculosis disease. As a result of this process a set of 17 new and updated recommendations for the screening of TB disease have been developed. These recommendations identify contacts of TB patients, people living with HIV, people exposed to silica, prisoners and other key populations to be prioritized for TB screening. The new guidance also recommends different tools for screening, namely symptom screening, chest radiography, computer-aided detection software, molecular WHO-approved rapid diagnostic tests, and C-reactive protein. The new recommendations are being released as part of a modular series of WHO guidance on TB and are accompanied by a complementary implementation guide
