ItemTeacher-Mediated Interventions to Support Child Mental Health Following a Disaster: A Systematic Review.(Public Library of Science (PLoS), 2015-12-08)OBJECTIVES: This review sought to identify, describe and assess the effectiveness of teacher-mediated interventions that aim to support child and adolescent recovery after a natural or man-made disaster. We also aimed to assess intervention applicability to rural and remote Australian school settings. METHOD: A systematic search of the academic literature was undertaken utilising six electronic databases (EBSCO, Medline, PsycINFO, Embase, ERIC and CINAHL) using terms that relate to: teacher-mediated and school-based interventions; children and adolescents; mental health and wellbeing; natural disasters and man-made disasters. This was supplemented by a grey literature search. RESULTS: A total of 20 articles reporting on 18 separate interventions were identified. Nine separate interventions had been evaluated using methodologically adequate research designs, with findings suggesting at least short-term improvement in student wellbeing outcomes and academic performance. CONCLUSIONS: Although none of the identified studies reported on Australian-based interventions, international interventions could be adapted to the Australian rural and remote context using existing psychosocial programs and resources available online to Australian schools. Future research should investigate the acceptability, feasibility and effectiveness of implementing interventions modelled on the identified studies in Australian schools settings.

ItemEvaluation of a Database for Tracking Cases of Child Sexual Abuse(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2017)Administrative databases are used by criminal justice professionals to guide specialist responses to crimes of child sexual abuse. Assumptions might be made that the database will be accurate, contemporaneous, complete, and meaningful; however, this may not be the case. The main aim of the current study was to critically evaluate a database used by practitioners for tracking cases of child sexual abuse, in order to identify evidence that may justify investment in improved data gathering and centralised information management systems. Three data quality dimensions were examined: (1) completeness, measured as data that were not missing and were of adequate breadth and depth, (2) accuracy, namely that the data are correct, and (3) believability, where the data may be regarded as credible or plausible. Results indicated that data quality was of concern for all three dimensions, with missing and inaccurate data found across a range of variables, and issues with believability found on two variables. The implications of these results for development of new data documentation methods are discussed.

ItemNo Preview AvailableBayesian Validation of the Indirect Immunofluorescence Assay and Its Superiority to the Enzyme-Linked Immunosorbent Assay and the Complement Fixation Test for Detecting Antibodies against Coxiella burnetii in Goat Serum(AMER SOC MICROBIOLOGY, 2016-06)Although many studies have reported the indirect immunofluorescence assay (IFA) to be more sensitive in detection of antibodies to Coxiella burnetii than the complement fixation test (CFT), the diagnostic sensitivity (DSe) and diagnostic specificity (DSp) of the assay have not been previously established for use in ruminants. This study aimed to validate the IFA by describing the optimization, selection of cutoff titers, repeatability, and reliability as well as the DSe and DSp of the assay. Bayesian latent class analysis was used to estimate diagnostic specifications in comparison with the CFT and the enzyme-linked immunosorbent assay (ELISA). The optimal cutoff dilution for screening for IgG and IgM antibodies in goat serum using the IFA was estimated to be 1:160. The IFA had good repeatability (>96.9% for IgG, >78.0% for IgM), and there was almost perfect agreement (Cohen's kappa > 0.80 for IgG) between the readings reported by two technicians for samples tested for IgG antibodies. The IFA had a higher DSe (94.8%; 95% confidence interval [CI], 80.3, 99.6) for the detection of IgG antibodies against C. burnetii than the ELISA (70.1%; 95% CI, 52.7, 91.0) and the CFT (29.8%; 95% CI, 17.0, 44.8). All three tests were highly specific for goat IgG antibodies. The IFA also had a higher DSe (88.8%; 95% CI, 58.2, 99.5) for detection of IgM antibodies than the ELISA (71.7%; 95% CI, 46.3, 92.8). These results underscore the better suitability of the IFA than of the CFT and ELISA for detection of IgG and IgM antibodies in goat serum and possibly in serum from other ruminants.

ItemNo long-term evidence of hyporesponsiveness after use of pneumococcal conjugate vaccine in children previously immunized with pneumococcal polysaccharide vaccine(Elsevier, 2016-06)Background: A randomized controlled trial in Fiji examined the immunogenicity and effect on nasopharyngeal carriage after 0, 1, 2, or 3 doses of 7-valent pneumococcal conjugate vaccine (PCV7; Prevnar) in infancy followed by 23-valent pneumococcal polysaccharide vaccine (23vPPV; Pneumovax) at 12 months of age. At 18 months of age, children given 23vPPV exhibited immune hyporesponsiveness to a micro-23vPPV (20%) challenge dose in terms of serotype-specific IgG and opsonophagocytosis, while 23vPPV had no effect on vaccine-type carriage. Objective: This follow-up study examined the long-term effect of the 12-month 23vPPV dose by evaluating the immune response to 13-valent pneumococcal conjugate vaccine (PCV13) administration 4 to 5 years later. Methods: Blood samples from 194 children (now 5-7 years old) were taken before and 28 days after PCV13 booster immunization. Nasopharyngeal swabs were taken before PCV13 immunization. We measured levels of serotype-specific IgG to all 13 vaccine serotypes, opsonophagocytosis for 8 vaccine serotypes, and memory B-cell responses for 18 serotypes before and after PCV13 immunization. Results: Paired samples were obtained from 185 children. There were no significant differences in the serotype-specific IgG, opsonophagocytosis, or memory B-cell response at either time point between children who did or did not receive 23vPPV at 12 months of age. Nasopharyngeal carriage of PCV7 and 23vPPV serotypes was similar among the groups. Priming with 1, 2, or 3 PCV7 doses during infancy did not affect serotype-specific immunity or carriage. Conclusion: Immune hyporesponsiveness induced by 23vPPV in toddlers does not appear to be sustained among preschool children in this context and does not affect the pneumococcal carriage rate in this age group.

ItemThe carbon footprint of treating patients with septic shock in the intensive care unit(College of Intensive Care Medicine of Australia and New Zealand, 2018-12-01)OBJECTIVE: To use life cycle assessment to determine the environmental footprint of the care of patients with septic shock in the intensive care unit (ICU). DESIGN, SETTING AND PARTICIPANTS: Prospective, observational life cycle assessment examining the use of energy for heating, ventilation and air conditioning; lighting; machines; and all consumables and waste associated with treating ten patients with septic shock in the ICU at BarnesJewish Hospital, St. Louis, MO, United States (US-ICU) and ten patients at Footscray Hospital, Melbourne, Vic, Australia (Aus-ICU). MAIN OUTCOME MEASURES: Environmental footprint, particularly greenhouse gas emissions. RESULTS: Energy use per patient averaged 272 kWh/day for the US-ICU and 143 kWh/day for the Aus-ICU. The average daily amount of single-use materials per patient was 3.4 kg (range, 1.0-6.3 kg) for the US-ICU and 3.4 kg (range, 1.2-8.7 kg) for the Aus-ICU. The average daily particularly greenhouse gas emissions arising from treating patients in the US-ICU was 178 kg carbon dioxide equivalent (CO2-e) emissions (range, 165-228 kg CO2-e), while for the Aus-ICU the carbon footprint was 88 kg CO2-e (range, 77-107 kg CO2-e). Energy accounted for 155 kg CO2-e in the US-ICU (87%) and 67 kg CO2-e in the Aus-ICU (76%). The daily treatment of one patient with septic shock in the US-ICU was equivalent to the total daily carbon footprint of 3.5 Americans' CO2-e emissions, and for the Aus-ICU, it was equivalent to the emissions of 1.5 Australians. CONCLUSION: The carbon footprints of the ICUs were dominated by the energy use for heating, ventilation and air conditioning; consumables were relatively less important, with limited effect of intensity of patient care. There is large opportunity for reducing the ICUs' carbon footprint by improving the energy efficiency of buildings and increasing the use of renewable energy sources.

ItemIntroduction: Postcolonial realms of memory in the francophone world(Liverpool University Press, 2016-01-06)In September 2020, the mayor of Paris, Anne Hidalgo, announced plans to unveil a statute of Solitude, a former slave who fought against the French reinstatement of slavery in Guadeloupe in 1802. Solitude was arrested during the revolt, sentenced to death, and hanged. The inauguration of a statue in her memory would constitute the first statue of a black woman to be put up in the French capital.

ItemNo Preview AvailableVitamin B-12, folate, iron, and vitamin A concentrations in rural Indian children are associated with continued breastfeeding, complementary diet, and maternal nutrition(OXFORD UNIV PRESS, 2011-11)BACKGROUND: Determinants of vitamin B-12, folate, iron, and vitamin A concentrations in young children in rural south Asia are poorly understood. These micronutrients are crucial for the production of hemoglobin and have other important physiologic functions. OBJECTIVE: We sought to develop explanatory models for concentrations of vitamin B-12, folate, ferritin, and retinol binding protein (RBP) in children aged between 1 and 2 y in rural Karnataka, India. DESIGN: We performed a cross-sectional study in 12-23-mo-old toddlers who lived in 2 rural districts of Karnataka, India. For each child, data concerning dietary, food-security, and sociodemographic and maternal factors were obtained, and serum vitamin B-12, folate, ferritin, and RBP were measured. Multiple regression and structural equation modeling were applied to determine associations with micronutrient concentrations. RESULTS: Of 396 sampled children, 254 children (65.6%) had at least one micronutrient deficiency. With the use of multiple regression, continued breastfeeding was independently associated with the concentration of each micronutrient [(log) vitamin B-12: standardized coefficient of -0.30 (P < 0.001); folate: standardized coefficient of +0.20 (P < 0.001); (log) ferritin: standardized coefficient of -0.18 (P = 0.004); (log) RBP: standardized coefficient of-0.21 (P < 0.001)]. Children who continued to breastfeed received less nutrition from complementary foods and belonged to poorer families with higher food insecurity. A structural equation model for children's vitamin B-12 concentrations was developed that highlighted the interrelation between wealth, continued breastfeeding, complementary diet, and vitamin B-12 concentrations in children. CONCLUSIONS: Micronutrient deficiencies are common in this population. Rural Indian children between 1 and 2 y of age who continue to breastfeed should be especially targeted during micronutrient-supplementation programs. This trial was registered in the Australian and New Zealand Clinical Trials Registry as ACTRN12611000596909.
