- Abstract
Several international large-scale assessments were conducted at the turn of the new century, and during the past two decades the Programme for International Student Assessment (PISA) completed seven cycles of assessment to facilitate practitioners' policy debates and governance. This study reviews PISA-related articles published in English and Chinese. Three literature databases were searched, with a focus on SSCI, CSSCI, and TSSCI journal publications. The frequency of publication was analyzed according to the author's country affiliation, type of journal, and research categories/themes. Findings indicate that research on student-, school- and system-level indicators with a focus on students' learning processes and outcomes as well as critiques of technical matters on PISA were frequent topics in the literature during the past two decades. Issues of equality and equity examined in the publications have implications for enhancing practitioners' capabilities in terms of policy making and governance.

- Abstract
Native biodiversity decline and non-native species spread are major features of the Anthropocene. Both processes can drive biotic homogenization by reducing trait and phylogenetic differences in species assemblages between regions, thus diminishing the regional distinctiveness of biotas and likely have negative impacts on key ecosystem functions. However, a global assessment of this phenomenon is lacking. Here, using a dataset of >200,000 plant species, we demonstrate widespread and temporal decreases in species and phylogenetic turnover across grain sizes and spatial extents. The extent of homogenization within major biomes is pronounced and is overwhelmingly explained by non-native species naturalizations. Asia and North America are major sources of non-native species; however, the species they export tend to be phylogenetically close to recipient floras. Australia, the Pacific and Europe, in contrast, contribute fewer species to the global pool of non-natives, but represent a disproportionate amount of phylogenetic diversity. The timeline of most naturalisations coincides with widespread human migration within the last ~500 years, and demonstrates the profound influence humans exert on regional biotas beyond changes in species richness., (© 2021.

- Abstract
Objective: To report incidence and characteristics of decisions to forgo life-sustaining therapies (DFLSTs) in the 282 ICUs who contributed to the SAPS3 database., Methods: We reviewed data on DFLSTs in 14,488 patients. Independent predictors of DFLSTs have been identified by stepwise logistic regression., Results: DFLSTs occurred in 1,239 (8.6%) patients [677 (54.6%) withholding and 562 (45.4%) withdrawal decisions]. Hospital mortality was 21% (3,050/14,488); 36.2% (1,105) deaths occurred after DFLSTs. Across the participating ICUs, hospital mortality in patients with DFLSTs ranged from 80.3 to 95.4% and time from admission to decisions ranged from 2 to 4 days. Independent predictors of decisions to forgo LSTs included 13 variables associated with increased incidence of DFLSTs and 7 variables associated with decrease incidence of DFLST. Among hospital and ICU-related variables, a higher number of nurses per bed was associated with increased incidence of DFLST, while availability of an emergency department in the same hospital, presence of a full time ICU-specialist and doctors presence during nights and week-ends were associated with a decreased incidence of DFLST., Conclusion: This large study identifies structural variables that are associated with substantial variations in the incidence and the characteristics of decisions to forgo life-sustaining therapies.

- Abstract
Background: The lack of reference sequences from well-identified mycorrhizal fungi often poses a challenge to the inference of taxonomic affiliation of sequences from environmental samples, and many environmental sequences are thus left unidentified. Such unidentified sequences belonging to the widely distributed ectomycorrhizal fungal genus Inocybe (Basidiomycota) were retrieved from GenBank and divided into species that were identified in a phylogenetic context using a reference dataset from an ongoing study of the genus. The sequence metadata of the unidentified Inocybe sequences stored in GenBank, as well as data from the corresponding original papers, were compiled and used to explore the ecology and distribution of the genus. In addition, the relative occurrence of Inocybe was contrasted to that of other mycorrhizal genera., Results: Most species of Inocybe were found to have less than 3% intraspecific variability in the ITS2 region of the nuclear ribosomal DNA. This cut-off value was used jointly with phylogenetic analysis to delimit and identify unidentified Inocybe sequences to species level. A total of 177 unidentified Inocybe ITS sequences corresponding to 98 species were recovered, 32% of which were successfully identified to species level in this study. These sequences account for an unexpectedly large proportion of the publicly available unidentified fungal ITS sequences when compared with other mycorrhizal genera. Eight Inocybe species were reported from multiple hosts and some even from hosts forming arbutoid or orchid mycorrhizae. Furthermore, Inocybe sequences have been reported from four continents and in climate zones ranging from cold temperate to equatorial climate. Out of the 19 species found in more than one study, six were found in both Europe and North America and one was found in both Europe and Japan, indicating that at least many north temperate species have a wide distribution., Conclusion: Although DNA-based species identification and circumscription are associated with practical and conceptual difficulties, they also offer new possibilities and avenues for research. Metadata assembly holds great potential to synthesize valuable information from community studies for use in a species and taxonomy-oriented framework.

Background: Recent data suggest that the risk of young-onset colorectal cancer (yCRC), in adults less than 50 years of age, is increasing. To confirm findings and identify contemporary trends worldwide, we conducted a systematic review of studies examining population-level trends in yCRC epidemiology.Methods: We searched MEDLINE (1946-2018), EMBASE (1974-2018), CINAHL (1982-2018), and Cochrane Database of Systematic Reviews (2005-2018) for studies that used an epidemiologic design, assessed trends in yCRC incidence or prevalence, and published in English. Extracted information included country, age cut-off for yCRC, and reported trends in incidence or prevalence (e.g. annual percent change [APC]). We pooled similarly reported trend estimates using random effects models.Results: Our search yielded 8695 articles and after applying our inclusion criteria, we identified 40 studies from 12 countries across five continents. One study assessed yCRC prevalence trends reporting an APCp of + 2.6 and + 1.8 among 20-39 and 40-49 year olds, respectively. 39 studies assessed trends in yCRC incidence but with substantial variability in reporting. Meta-analysis of the most commonly reported trend estimate yielded a pooled overall APCi of + 1.33 (95% CI, 0.97 to 1.68; p < 0.0001) that is largely driven by findings from North America and Australia. Also contributing to these trends is the increasing risk of rectal cancer as among 14 studies assessing cancer site, nine showed an increased risk of rectal cancer in adults less than 50 years with APCi up to + 4.03 (p < 0.001).Conclusions: Our systematic review highlights increasing yCRC risk in North America and Australia driven by rising rectal cancers in younger adults over the past two decades.

- Abstract
e-Prescription systems are key components and drivers of digital health. They can enhance the safety of the patients, and are gaining popularity in health care systems around the world. Yet, there is little knowledge on comparative international analysis of e-Prescription systems' architecture and digital security. We report, in this study, original findings from a comparative analysis of the e-Prescription systems in eight different countries, namely, Canada, United States, United Kingdom, Australia, Spain, Japan, Sweden, and Denmark. We surveyed the databases related to pharmacies, eHealth, e-Prescriptions, and related digital health websites for each country, and their system architectures. We also compared the digital security and privacy protocols in place within and across these digital systems. We evaluated the systems' authentication protocols used by pharmacies to verify patients' identities during the medication dispensing process. Furthermore, we examined the supporting systems/services used to manage patients' medication histories and enhance patients' medication safety. Taken together, we report, in this study, original comparative findings on the limitations and challenges of the surveyed systems as well as in adopting e-Prescription systems. While the present study was conducted before the onset of COVID-19, e-Prescription systems have become highly relevant during the current pandemic and hence, a deeper understanding of the country systems' architecture and digital security that can help design effective strategies against the pandemic. e-Prescription systems can help reduce physical contact and the risk of exposure to the virus, as well as the wait times in pharmacies, thus enhancing patient safety and improving planetary health.

There is a growing interest in English-speaking jurisdictions, including Australia, North America, Canada, the United Kingdom and New Zealand, about the prevention of sexual abuse perpetrated by children against other children. The aim of this review was to identify opportunities for research, policy and practice which could enhance the prevention agenda relating to the perpetration of sexual abuse by children through conducting a Critical Interpretive Synthesis. Eleven electronic databases were searched in the period from 22 April to 23 May 2013 and included: SocINDEX, Social Services Abstracts, Applied Social Sciences Index and Abstracts, Family and Society Studies Worldwide, Project Muse, PsychINFO, Family and Society Plus, Jstor, Expanded Academic ASAP, Web of Science and Google Scholar. Key individual journals were also searched, including Child Abuse and Neglect and the Journal of Interpersonal Violence, as well as the grey literature. The search was guided by the research question: How could the prevention agenda relating to sexual abuse perpetrated by children be enhanced? The systematic literature search yielded 3323 titles, and 34 of these papers were included in the final synthesis. The authors identified five domains operating in the evidence base: characteristics, causes, communications, interventions and treatments. A synthesising construct emerged from the review: prevention-enhancing interactions. This construct referred to the potential for enhancing the prevention agenda which exists as the evidence domains interact with one another, and with the public health model of prevention. The authors consider this review to be a timely contribution to the current agenda pertaining to sexual abuse perpetrated by children. It provides researchers, policy makers and practitioners in the field with an evidence-informed conceptualisation of opportunities for enhancing prevention work. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: Knowing the global incidence of colorectal cancer (CRC), by sex and age of onset, is of great importance for understanding the disease burden of CRC., Methods: The CRC incidence data, by cancer site, age of onset, sex, country, and year, were retrieved from the Cancer Incidence in Five Continents Vol. Plus database. Estimated annual percentage changes (EAPC) were calculated to quantify the temporal trends in the CRC age-standardized incidence rate., Results: Globally, the incidence of late-onset CRC was heterogeneous and remained increasing in most countries. The highest incidence of late-onset colon and rectal cancer was both found in males in Slovakia (156.5/100,000 and 121.5/100,000, respectively). The most pronounced increases were mostly observed in developing countries, such as Brazil (colon cancer: EAPC = 5.87, 95% CI 3.18, 8.63; rectal cancer: EAPC = 4.68; 95% CI 2.78, 6.62). The highest incidence of early-onset colon and rectal cancer was found in females in Switzerland (4.2/100,000) and in males in South Korea (4.6/100,000), respectively. The incidences of early-onset CRC were increased in parts of countries, including countries experiencing a decline in late-onset CRC incidence, such as the USA, Germany, and Australia. The temporal trends of colon cancer were mostly aligned with those of rectal in most countries, independent of sex and age of onset., Conclusion: The increase of early-onset CRC incidence suggests more prevention initiatives are urgently warranted for young adults in the near future. Targeted and effective prevention measures are still needed among elderly populations.

Different mechanisms have been proposed as explanations for seismic anisotropy at the base of the mantle, including crystallographic preferred orientation of various minerals (bridgmanite, post-perovskite and ferropericlase) and shape preferred orientation of elastically distinct materials such as partial melt. Investigations of the mechanism for D" anisotropy usually yield ambiguous results, as seismic observations rarely (if ever) uniquely constrain a mechanism or orientation and usually rely on significant assumptions to infer flow patterns in the deep mantle. Observations of shear wave splitting and polarities of SdS and PdP reflections off the D" discontinuity are among our best tools for probing D" anisotropy; however, currently available data sets cannot constrain one unique scenario among those suggested by the mineral physics literature. In this work, we determine via a forward modelling approach what combinations of body wave phases (e.g. SKS, SKKS and ScS) are required to uniquely constrain a mechanism for D" anisotropy. We test nine models based on single-crystal and polycrystalline elastic tensors provided by mineral physics studies. Our modelling predicts fast shear wave splitting directions for SKS, SKKS and ScS phases, as well as polarities of P- and S- wave reflections off the D" interface, for a range of propagation directions, via solution of the Christoffel equation. We run tests using randomly selected synthetic data sets based on a given starting model, controlling the total number of measurements, the azimuthal distribution, and the type of seismic phases. For each synthetic data set, we search over all possible elastic tensors and orientations to determine which are consistent with the synthetic data. Overall, we find it difficult to uniquely constrain the mechanism for anisotropy with a typical number of seismic anisotropy measurements (based on currently available studies) with only one measurement technique (SKS, SKKS, ScS or reflection polarities). However, data sets that include SKS, SKKS and ScS measurements or a combination of shear wave splitting and reflection polarity measurements increase the probability of uniquely constraining the starting model and its orientation. Based on these findings, we identify specific regions (i.e. North America, northwestern Pacific and Australia) of the lowermost mantle with sufficient ray path coverage for a combination of measurement techniques.

- Abstract
Background: Careful assessment of the reasons for discontinuation of active surveillance (AS) is required for men with prostate cancer (PCa)., Objective: Using Movember's Global Action Plan Prostate Cancer Active Surveillance initiative (GAP3) database, we report on reasons for AS discontinuation., Design, Setting, and Participants: We compared data from 10296 men on AS from 21 centres across 12 countries., Outcome Measurements and Statistical Analysis: Cumulative incidence methods were used to estimate the cumulative incidence rates of AS discontinuation., Results and Limitations: During 5-yr follow-up, 27.5% (95% confidence interval [CI]: 26.4-28.6%) men showed signs of disease progression, 12.8% (95% CI: 12.0-13.6%) converted to active treatment without evidence of progression, 1.7% (95% CI: 1.5-2.0%) continued to watchful waiting, and 1.7% (95% CI: 1.4-2.1%) died from other causes. Of the 7049 men who remained on AS, 2339 had follow-up for >5yr, 4561 had follow-up for <5yr, and 149 were lost to follow-up. Cumulative incidence of progression was 27.5% (95% CI: 26.4-28.6%) at 5yr and 38.2% (95% CI: 36.7-39.9%) at 10yr. A limitation is that not all centres were included due to limited information on the reason for discontinuation and limited follow-up., Conclusions: Our descriptive analyses of current AS practices worldwide showed that 43.6% of men drop out of AS during 5-yr follow-up, mainly due to signs of disease progression. Improvements in selection tools for AS are thus needed to correctly allocate men with PCa to AS, which will also reduce discontinuation due to conversion to active treatment without evidence of disease progression., Patient Summary: Our assessment of a worldwide database of men with prostate cancer (PCa) on active surveillance (AS) shows that 43.6% drop out of AS within 5yr, mainly due to signs of disease progression. Better tools are needed to select and monitor men with PCa as part of AS., (Copyright © 2018 European Association of Urology. Published by Elsevier B.V. All rights reserved.)

Background: The barriers to HIV testing and counselling that migrants encounter can jeopardize proactive HIV testing that relies on the fact that HIV testing must be linked to care. We analyse available evidence on HIV testing and counselling strategies targeting migrants and ethnic minorities in high-income countries. Methods: Systematic literature review of the five main databases of articles in English from Europe, North America and Australia between 2005 and 2009. Results: Of 1034 abstracts, 37 articles were selected. Migrants, mainly from HIV-endemic countries, are at risk of HIV infection and its consequences. The HIV prevalence among migrants is higher than the general population’s, and migrants have higher frequency of delayed HIV diagnosis. For migrants from countries with low HIV prevalence and for ethnic minorities, socio-economic vulnerability puts them at risk of acquiring HIV. Migrants have specific legal and administrative impediments to accessing HIV testing—in some countries, undocumented migrants are not entitled to health care—as well as cultural and linguistic barriers, racism and xenophobia. Migrants and ethnic minorities fear stigma from their communities, yet community acceptance is key for well-being. Conclusions: Migrants and ethnic minorities should be offered HIV testing, but the barriers highlighted in this review may deter programs from achieving the final goal, which is linking migrants and ethnic minorities to HIV clinical care under the public health perspective.

- Abstract
Aims: To estimate the effects of needle and syringe programmes (NSP) and opioid substitution therapy (OST), alone or in combination, for preventing acquisition of hepatitis C virus (HCV) in people who inject drugs (PWID)., Methods: Systematic review and meta-analysis. Bibliographic databases were searched for studies measuring concurrent exposure to current OST (within the last 6 months) and/or NSP and HCV incidence among PWID. High NSP coverage was defined as regular NSP attendance or ≥ 100% coverage (receiving sufficient or greater number of needles and syringes per reported injecting frequency). Studies were assessed using the Cochrane risk of bias in non-randomized studies tool. Random-effects models were used in meta-analysis., Results: We identified 28 studies (n = 6279) in North America (13), United Kingdom (five), Europe (four), Australia (five) and China (one). Studies were at moderate (two), serious (17) critical (seven) and non-assessable risk of bias (two). Current OST is associated with 50% [risk ratio (RR) =0.50, 95% confidence interval (CI) = 0.40-0.63] reduction in HCV acquisition risk, consistent across region and with low heterogeneity (I
2 = 0, P = 0.889). Weaker evidence was found for high NSP coverage (RR = 0.79, 95% CI = 0.39-1.61) with high heterogeneity (I2 = 77%, P = 0.002). After stratifying by region, high NSP coverage in Europe was associated with a 56% reduction in HCV acquisition risk (RR = 0.44, 95% CI = 0.24-0.80) with low heterogeneity (I2 = 12.3%, P = 0.337), but not in North America (RR = 1.58, I2 = 89.5%, P = < 0.001). Combined OST/NSP is associated with a 74% reduction in HCV acquisition risk (RR = 0.26, 95% CI = 0.07-0.89, I2 = 80% P = 0.007). According to Grades of Recommendation Assessment, Development and Evaluation (GRADE) criteria, the evidence on OST and combined OST/NSP is low quality, while NSP is very low., Conclusions: Opioid substitution therapy reduces risk of hepatitis C acquisition and is strengthened in combination with needle and syringe programmes (NSP). There is weaker evidence for the impact of needle syringe programmes alone, although stronger evidence that high coverage is associated with reduced risk in Europe., (© 2017 The Authors.

Aims To synthesize evidence and knowledge from published research about nurses' experiences of nurse-patient relationships with adult patients in general, acute inpatient hospital settings. Background While primary research on nurses' experiences has been reported, it has not been previously synthesized. Design Meta-ethnography. Data sources Published literature from Australia, Europe, and North America, written in English between January 1999-October 2009 was identified from databases: CINAHL, Medline, British Nursing Index and Psyc INFO. Review methods Qualitative studies describing nurses' experiences of the nurse-patient relationship in acute hospital settings were reviewed and synthesized using the meta-ethnographic method. Results Sixteen primary studies (18 papers) were appraised as high quality and met the inclusion criteria. The findings show that while nurses aspire to develop therapeutic relationships with patients, the organizational setting at a unit level is strongly associated with nurses' capacity to build and sustain these relationships. The organizational conditions of critical care settings appear best suited to forming therapeutic relationships, while nurses working on general wards are more likely to report moral distress resulting from delivering unsatisfactory care. General ward nurses can then withdraw from attempting to emotionally engage with patients. Conclusion The findings of this meta-ethnography draw together the evidence from several qualitative studies and articulate how the organizational setting at a unit level can strongly influence nurses' capacity to build and sustain therapeutic relationships with patients. Service improvements need to focus on how to optimize the organizational conditions that support nurses in their relational work with patients. [ABSTRACT FROM AUTHOR]

Abstract: A key environmental concern is pollution loads released from human activity, since excessive pollutant loads can cause significant public health and/or environmental impacts. A principal objective of environmental regulation is therefore to minimise pollutant releases. The most common approach to assessing and monitoring pollutant loads is through pollutant release databases, with such systems now operating throughout Europe, North America and Australia. This paper has compiled and analysed an extensive data set on Australian coal mining and associated pollutant emissions reported through the National Pollutant Inventory (NPI). In Australia, the coal industry has been growing rapidly over recent decades, and this is causing significant community concerns over cumulative environmental impacts. The pollutant loads and intensities from coal mining are analysed in conjunction with production data. The trends identified in this paper provide an important basis to understand the value of pollutant release and transfer registers, such as the NPI, and demonstrate the critical need to integrate such data with ongoing trends in industry and environmental management initiatives.

Journal of Advanced Nursing 69(2), 348-362. doi: 10.1111/j.1365-2648.2012.06013.x Abstract Aim. To report a Delphi study that was conducted to select process and outcome indicators that are relevant to study quality of care and impact of care pathways for patients hospitalized with exacerbation of chronic obstructive pulmonary disease. Background. Management of patients hospitalized with exacerbation of chronic obstructive pulmonary disease is suboptimal and outcomes are poor. To evaluate the impact of care pathways properly, relevant indicators need to be selected. Design. Delphi study. Methods. The study was conducted over 4 months in 2008, with 35 experts out of 15 countries, including 19 medical doctors, 8 nurses and 8 physiotherapists. Participants were asked to rate, for 72 process and 21 outcome indicators, the relevance for follow-up in care pathways for in-hospital management of exacerbation of chronic obstructive pulmonary disease. Consensus (agreement by at least 75% of the participants) that an indicator is relevant for follow-up was sought in two rounds. Results. Consensus was reached for 26 of 72 process indicators (36·1%) and 10 of 21 outcome indicators (47·6%). Highest consensus levels were found for the process indicators regarding oxygen therapy (100%), pulmonary rehabilitation (100%) and patient education (94·5-88·6%) and for the outcome indicators concerning understanding of therapy (91·4-85·7%) and self-management (88·6-88·2%). Conclusion. The selected indicators appear to be sensitive for improvement. Therefore, researchers and clinicians that want to study and improve the care for patients hospitalized with exacerbation of chronic obstructive pulmonary disease should primarily focus on these indicators.

- Abstract
In dairy cattle, the rate of genetic gain from genomic selection depends on reliability of direct genomic values (DGV). One option to increase reliabilities could be to increase the size of the reference set used for prediction, by using genotyped bulls with daughter information in countries other than the evaluating country. The increase in reliabilities of DGV from using this information will depend on the extent of genotype by environment interaction between the evaluating country and countries contributing information, and whether this is correctly accounted for in the prediction method. As the genotype by environment interaction between Australia and Europe or North America is greater than between Europe and North America for most dairy traits, ways of including information from other countries in Australian genomic evaluations were examined. Thus, alternative approaches for including information from other countries and their effect on the reliability and bias of DGV of selection candidates were assessed. We also investigated the effect of including overseas (OS) information on reliabilities of DGV for selection candidates that had weaker relationships to the current Australian reference set. The DGV were predicted either using daughter trait deviations (DTD) for the bulls with daughters in Australia, or using this information as well as OS information by including deregressed proofs (DRP) from Interbull for bulls with only OS daughters in either single trait or bivariate models. In the bivariate models, DTD and DRP were considered as different traits. Analyses were performed for Holstein and Jersey bulls for milk yield traits, fertility, cell count, survival, and some type traits. For Holsteins, the data used included up to 3,580 bulls with DTD and up to 5,720 bulls with only DRP. For Jersey, about 900 bulls with DTD and 1,820 bulls with DRP were used. Bulls born after 2003 and genotyped cows that were not dams of genotyped bulls were used for validation. The results showed that the combined use of DRP on bulls with OS daughters only and DTD for Australian bulls in either the single trait or bivariate model increased the coefficient of determination [(R(2)) (DGV,DTD)] in the validation set, averaged across 6 main traits, by 3% in Holstein and by 5% in Jersey validation bulls relative to the use of DTD only. Gains in reliability and unbiasedness of DGV were similar for the single trait and bivariate models for production traits, whereas the bivariate model performed slightly better for somatic cell count in Holstein. The increase in R(2) (DGV,DTD) as a result of using bulls with OS daughters was relatively higher for those bulls and cows in the validation sets that were less related to the current reference set. For example, in Holstein, the average increase in R(2) for milk yield traits when DTD and DRP were used in a single trait model was 23% in the least-related cow group, but only 3% in the most-related cow group. In general, for both breeds the use of DTD from domestic sources and DRP from Interbull in a single trait or bivariate model can increase reliability of DGV for selection candidates., (Copyright © 2015 American Dairy Science Association.

Management of renal anemia in the large and at-risk population of non-dialysis chronic kidney disease (CKD) patients is a critical issue. In particular, definition of the optimal hemoglobin (Hb) target for therapy is controversial but highly warranted by physicians and patients worldwide. Recently, international clinical practice guidelines have recommended delayed initiation of erythropoiesis-stimulating agents (ESA) and lower Hb target levels during maintenance therapy. However, geographical differences in terms of ESA dose needed to achieve a given Hb value can be evidenced, with US patients showing higher prevalence of ESA resistance. On the other hand, non-US patients are often maintained in a higher Hb range by means of low ESA doses. This critical point has never been addressed. Nevertheless, outside of the US, translating the restrictive recommendations of new guidelines, which are essentially based on trials in US patients, can lead to negative effects, such as an increased need for a blood transfusion, and worsening of quality of life. In this article we provide a reappraisal of current recommendations on anemia management in non-dialysis CKD in light of the geographical differences in individual responsiveness to ESA.

Background: A growing number of studies indicate that sensationalist reporting of suicide is associated with increases in suicide rates, but in the light of some negative findings, the issue has remained controversial. The aim of this study was to evaluate the best current evidence on the association between celebrity suicide stories and subsequent suicides. Methods: Literature searches of six data sources (Medline, Psychlit, Communication Abstracts, Education Resources Information Center, Dissertation Abstracts and Australian Public Affairs Database (APAIS)) were conducted. Studies were included if they (1) adopted an ecological design, (2) focused on celebrity suicide, (3) had completed suicide as outcome variable, (4) analysed suicide rates across all suicide methods, (5) used data from after World War II and (6) satisfied basic quality criteria. Results: 10 studies with totally 98 suicides by celebrities met the criteria. The pooled estimate indicated a change in suicide rates (suicides per 100 000 population) of 0.26 (95% CI 0.09 to 0.43) in the month after a celebrity suicide. There was substantial heterogeneity between studies, which was explained by the type of celebrity (entertainment elite vs others) and the region of study, as indicated by mixed-effects meta-regression. The region-of-study--specific effect of reporting a suicide by an entertainment celebrity was 0.64 (95% CI 0.55 to 0.73) in North America, 0.58 (95% CI 0.47 to 0.68) in Asia, 0.36 (95% CI -0.10 to 0.61) in Australia and 0.68 (95% CI 0.51 to 0.85) in Europe. There was no indication of publication bias. Conclusions: Reports on celebrity suicide are associated with increases in suicides. Study region and celebrity type appear to have an impact on the effect size. [ABSTRACT FROM AUTHOR]

Background: The utility of iron fortification of food to improve iron deficiency, anemia, and biological outcomes is not proven unequivocally. Objectives: The objectives were to evaluate 1) the effect of iron fortification on hemoglobin and serum ferritin and the prevalence of iron deficiency and anemia, 2) the possible predictors of a positive hemoglobin response, 3) the effect of iron fortification on zinc and iron status, and 4) the effect of iron-fortified foods on mental and motor development, anthropometric measures, and infections. Design: Randomized and pseudorandomized controlled trials that included food fortification or biofortification with iron were included. Results: Data from 60 trials showed that iron fortification of foods resulted in a significant increase in hemoglobin (0.42 g/dL; 95% CI: 0.28, 0.56; P < 0.001) and serum ferritin (1.36 µg/L; 95% CI: 1.23, 1.52; P < 0.001), a reduced risk of anemia (RR: 0.59; 95% CI: 0.48, 0.71; P < 0.001) and iron deficiency (RR: 0.48; 95% CI: 0.38, 0.62; P < 0.001), improvement in other indicators of iron nutriture, and no effect on serum zinc concentrations, infections, physical growth, and mental and motor development. Significant heterogeneity was observed for most of the evaluated outcomes. Sensitivity analyses and meta-regression for hemoglobin suggested a higher response with lower trial quality (suboptimal allocation concealment and blinding), use of condiments, and sodium iron edetate and a lower response when adults were included. Conclusion: Consumption of iron-fortified foods results in an improvement in hemoglobin, serum ferritin, and iron nutriture and a reduced risk of remaining anemic and iron deficient.

In situ measurements of soil moisture are invaluable for calibrating and validating land surface models and satellite-based soil moisture retrievals. In addition, long-term time series of in situ soil moisture measurements themselves can reveal trends in the water cycle related to climate or land cover change. Nevertheless, on a worldwide basis the number of meteorological networks and stations measuring soil moisture, in particular on a continuous basis, is still limited and the data they provide lack standardization of technique and protocol. To overcome many of these limitations, the International Soil Moisture Network (ISMN; http://www.ipf.tuwien.ac.at/insitu) was initiated to serve as a centralized data hosting facility where globally available in situ soil moisture measurements from operational networks and validation campaigns are collected, harmonized, and made available to users. Data collecting networks share their soil moisture datasets with the ISMN on a voluntary and no-cost basis. Incoming soil moisture data are automatically transformed into common volumetric soil moisture units and checked for outliers and implausible values. Apart from soil water measurements from different depths, important metadata and meteorological variables (e.g., precipitation and soil temperature) are stored in the database. These will assist the user in correctly interpreting the soil moisture data. The database is queried through a graphical user interface while output of data selected for download is provided according to common standards for data and metadata. Currently (status May 2011), the ISMN contains data of 19 networks and more than 500 stations located in North America, Europe, Asia, and Australia. The time period spanned by the entire database runs from 1952 until the present, although most datasets have originated during the last decade. The database is rapidly expanding, which means that both the number of stations and the time period covered by the existing stations are still growing. Hence, it will become an increasingly important resource for validating and improving satellite-derived soil moisture products and studying climate related trends. As the ISMN is animated by the scientific community itself, we invite potential networks to enrich the collection by sharing their in situ soil moisture data. [ABSTRACT FROM AUTHOR]

- Abstract
Unlabelled: Various methodological approaches have estimated the incidence of osteoporosis-related fractures, making comparisons difficult. This study estimated the incidence rates of non-traumatic fractures in 12 countries using standard definitions. Applying these rates to the 2010 population figures of these countries, a total of 5.2 million non-traumatic fractures were estimated, mostly in women., Purpose: The purpose of this study was to estimate annual country-, sex-, and age-specific incidence of non-traumatic hip, vertebral, and other fractures for women aged ≥50 and men ≥60 years and the number of fractures expected in 12 countries based on these incidence rates., Methods: Electronically indexed medical literature and relevant web sites were reviewed to identify studies reporting age- and sex-specific fracture incidence rates to obtain estimates of the proportion of fractures considered to be non-traumatic and to gather relevant census data. From these data, we extrapolated to estimate the number of fractures in 12 countries in North America, Europe, Japan, and Australia., Results: Annual non-traumatic hip fracture incidence rates were highest for women in Sweden, Denmark, and Finland. In women, vertebral fractures were more common than hip fractures. The incidence of vertebral fractures was highest among Scandinavian and Canadian women. In men, Scandinavians had the highest incidence of hip fractures, while Australian men had the highest incidence of vertebral fractures. Hip and vertebral fracture incidence increased steeply with age for both women and men. Age appears to exert less influence on the incidence of fractures at sites other than hip and vertebrae. In 2010, 5.2 million non-traumatic fractures were expected in the 12 countries studied, of which 2.8 million were at the hip or spine. Women accounted for most of the total non-traumatic fracture burden (77 %)., Conclusions: Non-traumatic fractures pose a significant burden, affecting millions of women and men in countries around the world each year.

Background: Migration has challenged society. Most people who move do so for economic reasons, but others move for more tragic reasons. The proportion of female migrants was slightly higher than that of male migrants, partly due to the longer life expectancy of women and the higher demand for female migrants in care‐related Jobs. The process may affect migrants' health, particularly in countries where healthcare is associated with high economic costs or insurance availability. A global systematic review of qualitative studies with meta‐synthesis was conducted. The results can be used to support health policy and clinical practice. Objective: To describe how migrants perceive and experience the process of migrating and how it affects their health. Search strategy: Databases consulted were Medline, PsychInfo, Cuiden, Cinahl, WOS, Scopus, Social Science Database, and Epistemonikos. Thirty‐four articles were selected for final meta‐synthesis. Inclusion criteria: All qualitative primary studies were included that describe the experiences or perceptions of migrants and refugees over 18 years that talk about their migration process and the impact on their health; written in English or Spanish between 2016 and 2021. Articles referring to second generations and those dealing with pathologies that pre‐date the migration process were excluded. Data extraction and synthesis: The COREQ and JBI templates were used as quality criteria. Studies mostly used a phenomenological methodology and in‐depth interviews, both individual and group, were used for data collection and narrative synthesis. Main results: Uncertainty emerges as a main category. Three other interrelated themes have a direct impact on migrants' health: Language, Social Networks and Work. There are several conditions in each of these that have a positive or negative impact on health. The gender condition appears in both work and social networks, positively and negatively. Discussion and conclusions: Health would be improved by having a stable job, which would facilitate access to health resources. Social networks and language are facilitators of access to a better job, but not the only condition. From a gender perspective, social networks can become a source of health problems, especially for women. The process of migration places women in a position of vulnerability due to the difficulties of reconciling family and work life. Job insecurity, workload, loss of family life or social isolation increase hopelessness and anxiety, leading to health problems. Public or patient contribution: As an academic review study, no patient contribution was required, and this study serves as a theoretical framework for more in‐depth research that will work with migrant populations. As a public contribution, this work provides evidence of the need to improve access to health for some populations, in line with the Sustainable Development Goals (SDGs) set for 2030.

- Abstract
Background: Reviews on the prevalence of blindness and low vision in persons of age 20 to 59 years are lacking. We have therefore carried out a review based on a Medline search., Methods: The review was confined to epidemiological studies performed in Western Europe, North America and Australia covering the age group 20 to 59 years where there were comparable definitions of blindness and low vision according to the IAPB and WHO classification of blindness and low vision., Results: Three surveys, four register studies and two studies based on multiple sources matched our selection criteria. Blindness and low vision are described separately. Blindness: Only one study, based on multiple sources, covered the whole age group 20 to 59 years. In this study the overall prevalence of blindness was 0.08%. The prevalence of blindness was 0.04% among those 20-39 years old, whereas in the age group 40-59 years it was 0.1% in two surveys and one study on multiple sources. However, the prevalence was higher, 0.5% among whites and 0.7% among colored, in The Baltimore Eye Study. The definition of blindness was similar in all three studies. Low vision: Three studies provided data on the prevalence of low vision in the age group 20-59 years, although the number of cases was very small. In one study the prevalence of a visual acuity < or = 6/24 to 6/48 was 0.07% and in another the prevalence was 0.17% using < 6/18 to 0.5/60. No person with low vision was found in the third study., Conclusions: The existing epidemiological data on blindness and low vision among adults aged 20 to 59 years are insufficient. Epidemiological studies based on multiple sources are needed for the study of rare conditions such as blindness and low vision.

- Abstract
Background and Purpose: Many investigators have approached ischemic stroke as a complex phenotype by dividing the ischemic stroke population into distinct subtypes. The purpose of this study was to review systematically the methods used to subtype ischemic stroke in recent genetic studies., Methods: The MEDLINE database was searched for articles pertaining to research on the genetics of human ischemic stroke published from January 2000 through January 2002. Abstracts and full-length reports were then sequentially screened to select articles pertaining to original case-control or cohort studies., Results: The initial search yielded 153 publications. Of 41 relevant articles, ischemic stroke was subtyped in 25 (61%). The most common standard subtyping system was the Cerebrovascular Classification of Diseases III system (9 articles). Of the subtyping systems used, 3 had previously published interrater reliability. The subtyping system was reported to have been prespecified in 1 study. Four articles reported using central adjudication. Two articles reported that the person doing the subtyping was blinded to genotype, and 2 reported that the person doing the genotyping was blinded to the patient's subtype status., Conclusions: When investigators subtyped ischemic stroke, they typically used either nonstandard classification systems or systems of undetermined reliability. Important methodological issues, including blinding and prespecification of the classification system, were rarely reported. Advances in methodology and scientific reporting standards would foster identification of subtype-specific genetic risk factors.

- Abstract
Aim: Development of an international longitudinal database to examine patterns, trends and changes in dental hygiene., Method: Three surveys of national dental hygienists' associations, mainly members of the International Federation of Dental Hygienists. Data were collected by mail in 1987, 1992 and 1998, using a 40-item questionnaire. Sample size increased over time; results presented are based on responses for 13, 15 and 19 countries respectively. Preliminary tabulations were circulated to respondents for validation., Results: Overall, characteristics of the profession were remarkably similar; most noteworthy was the scope of dental hygiene clinical practice. Regarding historical development, education and professional organisation, the profession was more similar than dissimilar. Greater variation was evident in terms of numbers, distribution, workforce behaviour, predominant work setting and remuneration. While apparent change over the relatively short period 1987 to 1998 was viewed with caution, several observations were of particular interest: marked increases in the supply of dental hygienists, scope of practice and range of practice settings, accompanied by a decline in mandated level of work supervision. A slight but gradual increase in independent dental hygiene practice also was noted., Conclusion: By 1998 the profiles reflected the vast majority of the world's population of dental hygienists. While rate of change varied across the countries examined, the nature of the change tended to be consistent, resulting in a continuing homogeneity in the profession worldwide. Changes and emerging trends should continue to be monitored in terms of improved access to quality oral health services and technical efficiency in the provision of those services.

Objective: To synthesize peer-reviewed primary research exploring factors associated with perceived stress impacting post-secondary students' academic success. Methods: A systematic review identified research conducted in North America, Europe, and Australia in the last ten years across 12 databases. Results: Of the 6,214 references screened, 14 English articles published between 2011 and 2018 were deemed relevant. Subsequent analysis characterized articles by study design, location, population, factors with a statistically significant relationship with both perceived stress and academic success, and future research directions. Findings reveal a complex relationship among overlapping factors associated with perceived stress on academic success at both the intrapersonal (eg, academic, demographic, psychological, attitudinal, and behavioral characteristics) and interpersonal levels (eg, social capital). Conclusions: Further research should measure the association of the identified factors to inform areas where resources could be targeted within post-secondary institutions to prevent stress from unduly impacting students' educational outcomes.

- Abstract
Background: Objective Structured Clinical Examinations (OSCEs) are a simulation-based assessment tool used extensively in medical education for evaluating clinical competence. OSCEs are widely regarded as more valid, reliable, and valuable compared to traditional assessment measures, and are now emerging within professional psychology training programs. While there is a lack of findings related to the quality of OSCEs in published psychology literature, psychometric properties can be inferred by investigating implementation. Accordingly, the current review assessed implementation of OSCEs within psychology programs against a set of Quality Assurance Guidelines (QAGs). Methods: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) recommendations. Electronic databases including ProQuest Psychology, PsycArticles, Psychology and Behavioural Sciences Collection, PsycInfo and key indexing databases such as Scopus, ProQuest, and Web of Science were used to identify relevant articles. Twelve full-text articles met all inclusion criteria and were included in the review. Results: There was considerable heterogeneity in the quality of studies and reporting of OSCE data. Implementation of OSCEs against QAGs revealed overall adherence to be "Fair." Conclusion: The current review consolidated what is known on psychometric quality of OSCEs within psychology programs. A further need for quantitative evidence on psychometric soundness of OSCEs within psychology training is highlighted. Furthermore, it is recommended that future training programs implement and report OSCEs in accordance with standardized guidelines.

Sexual abuse is a cross-cultural phenomenon related to multiple cultural contexts including religious affiliation. The Haredi, or Orthodox Jewish community (OJC), constitutes a significant minority group of the worldwide Jewish population, characterized by cultural conservatism, steadfast loyalty to the community, and strict religious behavioral codes. To date, only few empirical studies (as opposed to multiple media reports) have dealt with the issue of sexual abuse within the OJC. Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we conducted a systematic review of the literature on sexual abuse within the OJC and its subgroups that addresses experiences and reports of victims, perpetrators, the Jewish and general community, and professionals in the North America, Israel, and Australia. Articles were collected from peer-reviewed databases and bibliographies; 13 quantitative and qualitative articles were included in the final sample. Three themes emerged: disclosure of sexual abuse, perceptions and attitudes toward the abuse, and its implications. Results indicated that alongside several findings that were specifically grounded in the context of closed collective or religious societies and the OJC in particular, most essentially reflected universal aspects of sexual abuse. The results suggest promoting context-informed interventions based on community knowledge and resilience, together with appropriate training in order to better understand the needs of the OJC and of closed communities in general.

Background People who inject drugs (PWID) experience barriers to accessing testing and treatment for hepatitis C virus (HCV) infection. Opioid agonist therapy (OAT) may provide an opportunity to improve access to HCV care. This systematic review assessed the association of OAT and HCV testing, treatment, and treatment outcomes among PWID. Methods Bibliographic databases and conference presentations were searched for studies that assessed the association between OAT and HCV testing, treatment, and treatment outcomes (direct-acting antiviral [DAA] therapy only) among PWID (in the past year). Meta-analysis was used to pool estimates. Results Of 9877 articles identified, 22 studies conducted in Australia, Europe, North America, and Thailand were eligible and included. Risk of bias was serious in 21 studies and moderate in 1 study. Current/recent OAT was associated with an increased odds of recent HCV antibody testing (4 studies; odds ratio (OR), 1.80; 95% confidence interval [CI], 1.36–2.39), HCV RNA testing among those who were HCV antibody–positive (2 studies; OR, 1.83; 95% CI, 1.27–2.62), and DAA treatment uptake among those who were HCV RNA–positive (7 studies; OR, 1.53; 95% CI, 1.07–2.20). There was insufficient evidence of an association between OAT and treatment completion (9 studies) or sustained virologic response following DAA therapy (9 studies). Conclusions OAT can increase linkage to HCV care, including uptake of HCV testing and treatment among PWID. This supports the scale-up of OAT as part of strategies to enhance HCV treatment to further HCV elimination efforts. [ABSTRACT FROM AUTHOR]

- Abstract
This article provides a detailed analysis of the various methods used in physics classrooms to teach oscillation and its related concepts. We thoroughly searched reputable databases, including Scopus and Web of Science. We analyzed 50 articles published between 2018 and 2023 using content analysis techniques such as elimination, classification, and grouping into themes. Our unit of analysis was the articles' methods, results, and conclusions. The results of this study are: (1) The trends in the development of research on the topic of oscillation and its derivatives from 2018 to 2023 indicate a declining interest. (2) During the period from 2018 to 2023, Indonesia emerged as the primary contributor to research on the topic of oscillation; (3) From 2018 to 2023, researchers predominantly focused on the topic of pendulum in the field of oscillation research (4) The most prevalent method for imparting oscillation content and its derivatives employed by researchers between 2018 and 2023 was experimentation, and (5) The most prevalent type of empirical research conducted on the topic of oscillation between 2018 and 2023 was pure research involving laboratory experiments. This systematic literature review is a foundation for developing various learning tools such as teaching materials, technology-based instructional media development, and primarily instruments related to oscillation and its derivatives. Overall, this systematic review highlights the need for more research on effective teaching methods for oscillation and provides practical insights for educators and researchers alike.

Background: Breast cancer is the most common cancer in women worldwide, with a great diversity in outcomes among individual patients. The ability to accurately predict a breast cancer outcome is important to patients, physicians, researchers, and policy makers. Many models have been developed and tested in different settings. We systematically reviewed the prognostic models developed and/or validated for patients with breast cancer.Methods: We conducted a systematic search in four electronic databases and some oncology websites, and a manual search in the bibliographies of the included studies. We identified original studies that were published prior to 1st January 2017, and presented the development and/or validation of models based mainly on clinico-pathological factors to predict mortality and/or recurrence in female breast cancer patients.Results: From the 96 articles selected from 4095 citations found, we identified 58 models, which predicted mortality (n = 28), recurrence (n = 23), or both (n = 7). The most frequently used predictors were nodal status (n = 49), tumour size (n = 42), tumour grade (n = 29), age at diagnosis (n = 24), and oestrogen receptor status (n = 21). Models were developed in Europe (n = 25), Asia (n = 13), North America (n = 12), and Australia (n = 1) between 1982 and 2016. Models were validated in the development cohorts (n = 43) and/or independent populations (n = 17), by comparing the predicted outcomes with the observed outcomes (n = 55) and/or with the outcomes estimated by other models (n = 32), or the outcomes estimated by individual prognostic factors (n = 8). The most commonly used methods were: Cox proportional hazards regression for model development (n = 32); the absolute differences between the predicted and observed outcomes (n = 30) for calibration; and C-index/AUC (n = 44) for discrimination. Overall, the models performed well in the development cohorts but less accurately in some independent populations, particularly in patients with high risk and young and elderly patients. An exception is the Nottingham Prognostic Index, which retains its predicting ability in most independent populations.Conclusions: Many prognostic models have been developed for breast cancer, but only a few have been validated widely in different settings. Importantly, their performance was suboptimal in independent populations, particularly in patients with high risk and in young and elderly patients. [ABSTRACT FROM AUTHOR]- Published

- Abstract
The purpose of this study is to identify and characterize the state of social construction of learning in virtual communities within online learning environments and to identify the advances and research challenges of social learning. The method was a systematic mapping to analyze the evidence published on the topic in 2015-2020. We automatically searched the Scopus and Web of Science databases, applying inclusion and exclusion criteria to obtain the maximum relevant information. The pre-designed search strategy resulted in 187 articles. The main research topic addressed in most of these is learning as a social construction in training contexts, primarily virtual communities. In higher education, the United States is the country with the most active researchers on this topic. In addition, the most significant findings show that in a virtual learning community, social and cognitive interactions with teaching presence are crucial for students to build knowledge and achieve a higher level of learning. This study describes challenges related to the various methodologies, geographical scope, and types of social construction learning in virtual learning communities. This research is intended to be of value to teachers, decision-makers, designers of research and researchers interested in the social construction of learning in online learning environments.

Background: research in care home settings is often negatively focused, portraying life as sterile and devoid of meaningful experiences. Care homes have the potential to influence people's lives socially, physically and psychologically. It is important to understand what factors contribute to this.Objective: to conduct a systematic qualitative review of care home life and provide practical recommendations to enhance residents' quality of life.Methods: the following databases were searched: PsycINFO, Medline, Web of Science, EMBASE, Allied and Complementary Medicine Database and Cumulative Index to Nursing and Allied Health Literature. References from appropriate journals and individual articles were checked. Papers that fitted our selection criteria were selected. Two independent reviewers assessed methodological study quality. Thematic analysis and meta-ethnographic methods were adapted to synthesise findings.Results: thirty-one studies were identified. People in care homes voiced concerns about lack of autonomy and difficulty in forming appropriate relationships with others. Four key themes were identified: (i) acceptance and adaptation, (ii) connectedness with others, (iii) a homelike environment, (iv) caring practices.Conclusion: positive experiences in care homes can occur and are important for residents' quality of life. The review supports literature highlighting the need for relationship-centred approaches to care and emphasises the importance of understanding the resident's attitude towards living in care homes.

Aim: To undertake a systematic literature review to examine the effect of food cost on diet quality and risk factors for chronic disease, specifically focusing on diet-related lifestyle diseases affecting the Australian population. Methods: A search of six databases resulted in the inclusion of one systematic review, three cohort studies, 41 cross-sectional studies and four modelling studies in this review. Results: Between 2000 and 2006, the price of healthy foods has increased more than the price of less healthy foods. Healthy Food Access Basket surveys show that a healthy diet may often be unaffordable for low- and average-income households. Diets of higher energy density were associated with lower diet cost, whereas diets of higher nutrient density and nutritional quality were associated with higher diet cost. Recent studies report an inverse association between food price and food consumption. Consequently, an increase in food cost was associated with a significant reduction in weight, waist circumference, body mass index, obesity and insulin resistance. Conclusions: Manipulation of food cost may alter food consumption and therefore risk factors for chronic disease. Further longitudinal studies investigating the impact of pricing strategies on diet quality and disease risk are needed. [ABSTRACT FROM AUTHOR]

Agri‐environmental schemes (AESs) are increasingly implemented to promote the adoption of environmentally friendly practices by farmers. We use a systematic review to explore the role of behavioural factors and opportunity costs in farmers' decisions to participate in AESs in Australia, Europe and North America. Behavioural factors influence how farmers value and perceive options, while opportunity costs relate to farmers' forgone utility when choosing to participate in schemes. We synthesise insights from 79 articles and over 700 factors explaining the participation in AESs. We find that a set of behavioural factors seem consistently connected to participation, including agricultural training, advice and having positive attitudes towards AESs. Moreover, several factors related to opportunity costs also have a rather consistent relationship with AES participation, including market conditions, implementation efforts, profitability, and management and contract flexibility. However, many relationships of behavioural factors and opportunity costs with AES participation are not as consistent and generalizable as sometimes portrayed and require context‐specific interpretation. Those factors with mixed results can still provide insights into farmers' participation decisions as several of them are either 'positively and insignificantly' or 'negatively and insignificantly' related to participation, such as environmental attitude, trust and farm size. These results suggest that their relationship with AES participation depends on other factors or the setting, highlighting interactions and raising important new research questions. Overall, our results provide several entry points for both researchers and policy‐makers, highlighting uncertainties in relationships between factors and participation that should be considered when designing policies.

- Abstract
The COVID-19 pandemic has struck many countries around the world. Most countries declared a health emergency to halt the spread of COVID-19 cases, putting all citizens on lockdown. This has caused schools to implement distance learning strategies with little or no prior experience. The COVID-19 pandemic has pushed the world's education system into an unstructured, emergency remote education mode. New issues arise as a result of the change from offline to online instruction, as well as achieving work-life balance. Hence this systematics review was guided by Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) in order to identify the current research on teacher technostress. The factors that contribute to the said factor and ways of overcoming teachers' technostress during online learning would be investigated. A number of 52 related studies were accessed from Jun 2021 until September 2021 for this study. Articles published between 2019 and 2021 were sought from two leading databases which are Web of Science (WOS) and Scopus. Thus, this review systematically identifies teacher technostress and coping mechanisms during COVID-19 pandemic. It was found that several effects were caused by the technology use. In light of the result, stakeholders need to prepare a proactive way to make sure teachers are less stressed with this new norm of teaching and learning.

Background: The modified Dunn procedure facilitates femoral capital realignment for slipped capital femoral epiphysis (SCFE) through a surgical hip dislocation approach. Iatrogenic postoperative hip instability after this procedure has not been studied previously; however, we were concerned when we observed several instances of this serious complication, and we wished to study it further.Questions/purposes: The purpose of this study was to evaluate the frequency, timing, and clinical presentation (including complications) associated with iatrogenic instability after the modified Dunn procedure for SCFE.Methods: Between 2007 and 2014, eight international institutions performed the modified Dunn procedure through a surgical dislocation approach in 406 patients. During the period in question, indications varied at those sites, but the procedure was used only in a minority of their patients treated surgically for SCFE (31% [406 of 1331]) with the majority treated with in situ fixation. It generally was performed for patients with severe deformity with a slip angle greater than 40°. Institutional databases were searched for all patients with SCFE who developed postoperative hip instability defined as hip subluxation or dislocation of the involved hip during the postoperative period. We reviewed in detail the clinical notes and operative records of those who presented with instability. We obtained demographic information, time from slip to surgery, type of fixation, operative details, and clinical course including the incidence of complications. Followup on those patients with instability was at a mean of 2 years (range, 1-5 years) after the index procedure. Complications were graded according to the modified Dindo-Clavien classification. Radiographic images were reviewed to measure the preoperative slip angle and the presence of osteonecrosis.Results: A total of 4% of patients treated with the modified Dunn procedure developed postoperative hip instability (17 of 406). Mean age of the patients was 13 years (range, 9-16 years). Instability presented as persistent hip pain in the postoperative period or was incidentally identified radiographically during the postoperative visit and occurred at a median of 3 weeks (range, 1 day to 2 months) after the modified Dunn procedure. Eight patients underwent revision surgery to address the postoperative instability. Fourteen of 17 patients developed femoral head avascular necrosis and three of 17 patients underwent THA during this short-term followup.Conclusions: Anterolateral hip instability after the modified Dunn procedure for severe, chronic SCFE is an uncommon yet potentially devastating complication. Future studies might evaluate the effectiveness of maintaining anterior hip precautions for several weeks postoperatively in an abduction brace or broomstick cast to prevent this complication.Level Of Evidence: Level IV, therapeutic study.

Objective Paediatric head injury is a common presentation to the ED. North American studies demonstrate increasing use of computed tomography (CT) brain scan (CTB) to investigate head injury. No such data exists for Australian EDs. The aim of this study was to describe CTB use in head injury over time in eight Australian EDs. Methods Retrospective ED electronic database and medical imaging database audit was undertaken for the years 2001-2010 by International Classification of Diseases (ICD) 9 or 10 code for head injury in children <16 years. EDs and medical imaging departments of eight hospitals in Australia (five tertiary referral and three mixed departments). Data for ED presentations with head injury, and all CTB performed by medical imaging were merged to obtain a data set of CTB performed within 24 h for head injury-related attendances to the ED. Descriptive and comparative analysis of CTB rates was performed. Results The rate of CTB over the decade was 10.2% (95% confidence interval (CI) 9.9-10.5). The annual rate varied from 9.5% (95% CI 8.2-10.9) to 12.5% (95% CI 11.2-13.9). CTB use did not increase over time. Median year of age at time of CT scan was 4 years, with an interquartile range of 1.5-9.4 years. Overall there was a 9.2% increase in the CTB scan rate for every additional year of age at presentation (95% CI 6.6-12.1; P < 0.001). Conclusion CTB use in head injuries did not increase during the study period, and rates of CTB were less than reported for North America. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: To gather research evidence on the association between diet and depression and anxiety among college students. Methods: Systematic searches were performed in CINAHL, PsycINFO, PubMed, and ScienceDirect databases to identify potentially relevant articles published between January 2000 and September 2020. Data were extracted from 21 selected studies. Results: Most of the cross-sectional studies found a positive association between diet and depression and anxiety; however, a few studies found inconsistent results. Moreover, several interventional studies demonstrated that a healthy diet (including consumption of fruit and vegetables) improved depression in the intervention group. Conclusions: The methodological limitations of cross-sectional studies to explain causality and the limited number of prospective interventional studies point to a pressing need to conduct more prospective, longitudinal, and randomized controlled trials to generalize the causal associations between diet and depression and anxiety. Further research is needed to investigate the biological mechanisms of nutrients' actions on anxiety and depression.

- Abstract
Objective: To synthesize peer-reviewed primary research exploring factors associated with perceived stress impacting post-secondary students' academic success. Methods: A systematic review identified research conducted in North America, Europe, and Australia in the last ten years across 12 databases. Results: Of the 6,214 references screened, 14 English articles published between 2011 and 2018 were deemed relevant. Subsequent analysis characterized articles by study design, location, population, factors with a statistically significant relationship with both perceived stress and academic success, and future research directions. Findings reveal a complex relationship among overlapping factors associated with perceived stress on academic success at both the intrapersonal (eg, academic, demographic, psychological, attitudinal, and behavioral characteristics) and interpersonal levels (eg, social capital). Conclusions: Further research should measure the association of the identified factors to inform areas where resources could be targeted within post-secondary institutions to prevent stress from unduly impacting students' educational outcomes.

- Abstract
The purpose of this scoping review is to critically examine empirical research that draws on first-person experiences of schooling among students with autism or attention-deficit/hyperactivity disorder (ADHD) as well as to map whose voices are heard in research and where the current knowledge gaps are. The review examined key characteristics of this body of research in relation to the publication context and research methodology. Studies were identified through a systematic scoping review of research published between January 2000 and December 2021 in four electronic databases and a subsequent ancestry search. Fifty-eight articles met the inclusion criteria. The results show an increased research interest in first-person accounts of schooling from 2016 onwards. The autism voice dominated over ADHD and was strongly skewed towards the academically able group. There was an overrepresentation of boys and secondary school children across the studies. Characteristics such as the child's social class, ethnicity and socioeconomic background were largely neglected, with details associated with the diagnosis being foregrounded. Interviewing was the main method used, and student perspectives were often accompanied by other data sources. The article concludes with a discussion on the silencing of already marginalised sub-groups and the importance of approaching research as an ethical enterprise.

- Abstract
Parents play a unique role in providing and facilitating their children in acquirement of sexual and reproductive health knowledge. The purpose of this study is to provide an overview of parents' attitude, preferences towards sexuality education (SE) and factors that contributed to their attitudes and perceptions based on review of relevant literature. The articles were retrieved via electronic databases, and manually examined to identify the studies that addressed the research questions. There were 29 studies with a total of 22,213 parents involved which published in peer-reviewed journals between the year 2000 and 2018 were selected and reviewed systematically. The findings emerged from the review were categorized into three main themes which included parental attitudes, parental preferences towards the implementation of SE and the factors contributed to their attitudes and perceptions. Most studies revealed that parents showed positive attitudes and support the inclusion of SE in school. They preferred age-appropriated SE to be introduced in elementary schools and secondary schools. Some parents supported SE which is aligned with religious teaching and cultural. Demographic factors, parents' sexuality knowledge, religious and cultural factors could affect parental attitudes and perceptions towards SE. This understanding could be useful for policymakers and educators to encourage collaboration with parents to strengthen the effectiveness of the program and scale up SE to benefit the young generation.

Background: Whether medical education research (MER) is primarily conducted in wealthy countries (in the "Realm of the Rich") is the subject of an ongoing debate. Previous studies of the geography of MER publication output have relied upon proprietary databases, have not compared MER with other fields of study, and have not studied the relationship between authorship geography and topics of study. This study was designed to evaluate the geographic distribution of MER authorship and to relate this to the topics studied in MER. Methods: Authors' countries of affiliation were identified from PubMed records by parsing and cleaning the text of affiliations and submitting them to the google maps geocoding API. The geography of publication output in MER was compared to other fields using the chi-square goodness-of-fit test. Country income classifications and medical subject heading (MeSH) terms were used to evaluate the topical contributions of countries at different income levels, and simulation was used to compute significance of MeSH term enrichment in MER papers from low income and lower middle income countries. Results: The vast majority of MER papers were contributed by authors based in high income countries. The top four countries were the United States, the United Kingdom, Canada, and Australia, with listed author affiliations in 80% of all MER papers. This percentage was greater in MER than in several other categories, including Biological Science Disciplines (48%), Medicine (69%) and Education (74%), which is a parent category of MER. Authors from low income countries contributed significantly to the topical diversity of MER. MeSH terms associated with government, community health, and health delivery were enriched in papers from low income countries, while terms associated with specialty and clinical training, technology in teaching, and professional obligations (such as workload, burnout, and empathy) were enriched in papers from high income countries. Conclusions: Geographic disparities in publication output are greater in MER than in any other field examined. The historical origins of MER in North America might explain disproportionate publication output by authors from this region. This study suggests that the MER field benefits from research contributed by authors from low income countries, and also points to potential gaps in MER (and medical education as a whole) in the developing world.
