Innovation in literacy and numeracy using e-learning technologies in Australian primary schools 2002

The 2002 Commonwealth Bank e-Learning Grants program provided $350,000 in additional funding to primary schools across all states and territories and education sectors. The grant application process provided the data for this study. The 2002 e- Learning Grants program, through the grant application process, has provided an invaluable opportunity to gain an insight into the way in which teachers and construct innovative e-learning projects within the context of their school. It has also provided a national ‘snapshot’ of the levels of school ICT infrastructure in primary schools. Implicit in government policies and the significant investment in technology is the belief that integration of ICT into Australian schools will have a ’transforming’ effect on education. By 2002 the average ratio of computers to students in state and territory government schools was 1 to 5.3. Achieving such ratios has been a direct result of the policies of state and territory governments and individual schools. While the impact of ICT on curriculum is at an early stage the 2002 e-Learning Grant applications indicate that they have the potential to challenge the structure of schools, the curriculum and the pedagogies employed by teachers as they integrate ICT’s into their classrooms.

Principles of Pretrial Release: Reforming Bail Without Repeating its Harms

Bail reform is happening. Across the country, jurisdictions are beginning to recognize that contemporary pretrial systems rooted in money bail are discriminatory, ineffective, and (by and large) unconstitutional. A common and substantial component of contemporary reforms is an increased reliance on conditional release as an alternative to pretrial incarceration. In many ways, conditional release represents an improvement over money bail, but the practice of conditional release has its own pitfalls. This Article identifies unforeseen and unplanned harms that can result from a system of conditional release and proposes five principles that jurisdictions can follow to eliminate or mitigate these harms. As the options for pretrial conditions continue to expand, judges may impose more conditions than are necessary, including conditions that are burdensome and ineffective. Because pretrial monitoring is inexpensive—especially when subsidized by user fees for pretrial monitoring—there is a risk that courts will impose monitoring and other conditions on people who would previously have been released without conditions. Taken together, these harms can prolong people’s involvement in the criminal justice system, restrict their liberty in profound ways, set them up for pretrial incarceration through technical violations, and saddle them with unaffordable debts. To responsibly use conditional release without replicating the harms of money bail, jurisdictions should adopt the following five principles. One, release on recognizance should be the norm and conditional release the exception. Two, the principle of parsimony should guide decisions over what conditions of release to impose—meaning that burdens placed on defendants and restrictions of their liberty should not exceed the legitimate interests of the government. Three, conditions should be minimal, related to the charged conduct, and proportionate to the risk of flight and pretrial criminal activity. Four, jurisdictions should not charge fees for conditional release, pretrial services, or pretrial monitoring. Five, restrictions on pretrial liberty should be evidence-based

Geometric mismatch of pulmonary and aortic anuli in children undergoing the Ross procedure: Implications for surgical management and autograft valve function

AbstractBackground: There is often substantial mismatch between the diameters of the pulmonary and aortic anuli in young patients with systemic outflow tract disease. To implant the autologous pulmonary valve in the aortic position under such circumstances, it is necessary to adapt the geometry of the systemic outflow tract. The effects of such adaptations on autograft function in children are not well known. Methods: To determine factors predictive of autograft regurgitation, we analyzed 41 cases of children who have undergone the Ross procedure. The diameter of the pulmonary valve was greater (by at least 3 mm) than that of the aortic valve in 20 cases, equal (within 2 mm) in 12 cases, and less (by at least 3 mm) in nine cases, with differences ranging from +10 to –12 mm. In 12 patients with a larger pulmonary anulus, aortoventriculoplasty was used to correct the mismatch. In patients with a larger aortic anulus, the mismatch was corrected by gradual adjustment along the circumference of the autograft, rather than by tailoring of the native aortic anulus. Results: At follow-up (median 31 months), two patients had undergone reoperation on the neoaortic valve for moderate regurgitation. In the remaining 38 cases, autograft regurgitation was as follows: none or trivial in 30, mild in seven, and moderate in one. There was no correlation between regurgitation and age, geometric mismatch, or previous or concurrent procedures. Conclusions: Subtle technical factors that may result in distortion of the valve complex are probably more important determinants of autograft regurgitation than are indication for repair, geometric mismatch, or previous or concomitant outflow tract procedures. Significant mismatch of the semilunar anuli is not a contraindication to the Ross procedure in children. (J Thorac Cardiovasc Surg 1998;115:1255-63

Exploring the Experiences of the Consent Process for Aboriginal and Torres Strait Islander People Having Cardiac Surgery and Participating in Medical Research: A Study Protocol

Background: Gaining informed consent is a critical step before any medical procedure, and before taking part in medical research. Cultural differences in concepts of health and healing, communication, language, and racism, can play a part in forming barriers to gaining informed consent for Aboriginal and Torres Strait Islander people. For Aboriginal and Torres Strait Islander people, a lack of informed consent can worsen distrust and contribute to continuing health disparities. This protocol describes a study aimed at providing a better understanding of informed consent experiences of Aboriginal and Torres Strait Islander people undergoing heart surgery and participating in research. This will be complemented by comparing those experiences to the ones of the clinicians and researchers who obtain informed consent from Aboriginal and Torres Strait Islander people. Methods: The study will be conducted at the Fiona Stanley Hospital in Western Australia and Townsville University Hospital in Queensland. Participants will include Aboriginal and Torres Strait Islander patients undergoing cardiac surgery, clinicians of the cardiothoracic surgery team and medical researchers at both hospitals. Yarning will be used as an Indigenous research method to collect meaningful data from Aboriginal and Torres Strait Islander people undergoing cardiac surgery whilst semi-structured interviews will be conducted to explore Clinician’s and researchers’ experiences. Data from Aboriginal and Torres Strait Islander participant will be analysed following a cyclical approach to ensure Aboriginal and Torres Strait Islander voices are not lost during data interpretation. Inductive thematic analysis of data will be conducted to yield practical recommendations. Conclusions: We present the protocol of a study that will inform the development of strategies to ensure that informed consent processes are culturally appropriate and guarantee Aboriginal and Torres Strait Islander people’s right to self-determination. This will contribute to the provision of culturally safe healthcare services and promote the conduct of medical research that is ethical, safe and benefits Aboriginal and Torres Strait Islander people

The Rome III Criteria for the Diagnosis of Functional Dyspepsia in Secondary Care Are Not Superior to Previous Definitions

BACKGROUND & AIMS: Although the Rome III criteria for functional dyspepsia were defined 7 years ago, they have yet to be validated in a rigorous study. We addressed this issue in a secondary-care population. METHODS: We analyzed complete symptom, upper gastrointestinal (GI) endoscopy, and histology data from 1452 consecutive adult patients with GI symptoms at 2 hospitals in Hamilton, Ontario, Canada. Assessors were blinded to symptom status. Individuals with normal upper GI endoscopy and histopathology findings from analyses of biopsy specimens were classified as having no organic GI disease. The reference standard used to define the presence of true functional dyspepsia was epigastric pain, early satiety or postprandial fullness, and no organic GI disease. Sensitivity, specificity, and positive and negative likelihood ratios (LRs), with 95% confidence intervals (CIs), were calculated. RESULTS: Of the 1452 patients, 722 (49.7%) met the Rome III criteria for functional dyspepsia. Endoscopy showed organic GI disease in 170 patients (23.5%) who met the Rome III criteria. The Rome III criteria identified patients with functional dyspepsia with 60.7% sensitivity, 68.7% specificity, a positive LR of 1.94 (95% CI, 1.69-2.22), and a negative LR of 0.57 (95% CI, 0.52-0.63). In contrast, the Rome II criteria identified patients with functional dyspepsia with 71.4% sensitivity, 55.6% specificity, a positive LR of 1.61 (95% CI, 1.45-1.78), and a negative LR of 0.51 (95% CI, 0.45-0.58). The area under a receiver operating characteristics curves did not differ significantly for any of the diagnostic criteria for functional dyspepsia. CONCLUSIONS: In a validation study of 1452 patients with GI symptoms, the Rome III criteria performed only modestly in identifying those with functional dyspepsia, and were not significantly superior to previous definitions

The Welsh study of mothers and babies: protocol for a population-based cohort study to investigate the clinical significance of defined ultrasound findings of uncertain significance

Background Improvement in ultrasound imaging has led to the identification of subtle non-structural markers during the 18 – 20 week fetal anomaly scan, such as echogenic bowel, mild cerebral ventriculomegaly, renal pelvicalyceal dilatation, and nuchal thickening. These markers are estimated to occur in between 0.6% and 4.3% of pregnancies. Their clinical significance, for pregnancy outcomes or childhood morbidity, is largely unknown. The aim of this study is to estimate the prevalence of seven markers in the general obstetric population and establish a cohort of children for longer terms follow-up to assess the clinical significance of these markers. Methods/Design All women receiving antenatal care within six of seven Welsh Health Boards who had an 18 to 20 week ultrasound scan in Welsh NHS Trusts between July 2008 and March 2011 were eligible for inclusion. Data were collected on seven markers (echogenic bowel, cerebral ventriculomegaly, renal pelvicalyceal dilatation, nuchal thickening, cardiac echogenic foci, choroid plexus cysts, and short femur) at the time of 18 – 20 week fetal anomaly scan. Ultrasound records were linked to routinely collected data on pregnancy outcomes (work completed during 2012 and 2013). Images were stored and reviewed by an expert panel. The prevalence of each marker (reported and validated) will be estimated. A projected sample size of 23,000 will allow the prevalence of each marker to be estimated with the following precision: a marker with 0.50% prevalence to within 0.10%; a marker with 1.00% prevalence to within 0.13%; and a marker with 4.50% prevalence to within 0.27%. The relative risk of major congenital abnormalities, stillbirths, pre-term birth and small for gestational age, given the presence of a validated marker, will be reported. Discussion This is a large, prospective study designed to estimate the prevalence of markers in a population-based cohort of pregnant women and to investigate associations with adverse pregnancy outcomes. The study will also establish a cohort of children that can be followed-up to explore associations between specific markers and longer-term health and social outcomes

Author Correction: Ecology, evolution and spillover of coronaviruses from bats.

In the past two decades, three coronaviruses with ancestral origins in bats have emerged and caused widespread outbreaks in humans, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Since the first SARS epidemic in 2002–2003, the appreciation of bats as key hosts of zoonotic coronaviruses has advanced rapidly. More than 4,000 coronavirus sequences from 14 bat families have been identified, yet the true diversity of bat coronaviruses is probably much greater. Given that bats are the likely evolutionary source for several human coronaviruses, including strains that cause mild upper respiratory tract disease, their role in historic and future pandemics requires ongoing investigation. We review and integrate information on bat–coronavirus interactions at the molecular, tissue, host and population levels. We identify critical gaps in knowledge of bat coronaviruses, which relate to spillover and pandemic risk, including the pathways to zoonotic spillover, the infection dynamics within bat reservoir hosts, the role of prior adaptation in intermediate hosts for zoonotic transmission and the viral genotypes or traits that predict zoonotic capacity and pandemic potential. Filling these knowledge gaps may help prevent the next pandemic

HBV Infection in Relation to Consistent Condom Use: A Population-Based Study in Peru

Data on hepatitis B virus (HBV) prevalence are limited in developing countries. There is also limited information of consistent condom use efficacy for reducing HBV transmission at the population level. The study goal was to evaluate the prevalence and factors associated with HBV infection in Peru, and the relationship between anti-HBc positivity and consistent condom use.Data from two different surveys performed in 28 mid-sized Peruvian cities were analyzed. Participants aged 18-29 years were selected using a multistage cluster sampling. Information was collected through a validated two-part questionnaire. The first part (face-to-face) concerned demographic data, while the second part (self-administered using handheld computers) concerned sexual behavior. Hepatitis B core antibody (anti-HBc) was tested in 7,000 blood samples. Prevalences and associations were adjusted for sample strata, primary sampling units and population weights. Anti-HBc prevalence was 5.0% (95%CI 4.1%-5.9%), with the highest prevalence among jungle cities: 16.3% (95%CI 13.8%-19.1%). In the multivariable analysis, Anti-HBc positivity was directly associated with geographic region (highlands OR = 2.05; 95%CI 1.28-3.27, and jungle OR = 4.86; 95%CI 3.05-7.74; compared to coastal region); and inversely associated with age at sexual debut (OR = 0.90; 95%CI 0.85-0.97). Consistent condom use, evaluated in about 40% of participants, was associated with reduced prevalence (OR = 0.34; 95%CI 0.15-0.79) after adjusting for gender, geographic region, education level, lifetime number of sex partners, age at sexual debut and year of survey.Residence in highlands or jungle cities is associated with higher anti-HBc prevalences, whereas increasing age at sexual debut were associated with lower prevalences. Consistent condom use was associated with decreased risk of anti-HBc. Findings from this study emphasize the need of primary prevention programs (vaccination) especially in the jungle population, and imply that condom use promotion might be a potential strategy to prevent HBV infection
