Family-based prevention programmes for alcohol use in young people.

BACKGROUND: Alcohol use in young people is a risk factor for a range of short- and long-term harms and is a cause of concern for health services, policy-makers, youth workers, teachers, and parents. OBJECTIVES: To assess the effectiveness of universal, selective, and indicated family-based prevention programmes in preventing alcohol use or problem drinking in school-aged children (up to 18 years of age).Specifically, on these outcomes, the review aimed:• to assess the effectiveness of universal family-based prevention programmes for all children up to 18 years ('universal interventions');• to assess the effectiveness of selective family-based prevention programmes for children up to 18 years at elevated risk of alcohol use or problem drinking ('selective interventions'); and• to assess the effectiveness of indicated family-based prevention programmes for children up to 18 years who are currently consuming alcohol, or who have initiated use or regular use ('indicated interventions'). SEARCH METHODS: We identified relevant evidence from the Cochrane Central Register of Controlled Trials (CENTRAL), in the Cochrane Library, MEDLINE (Ovid 1966 to June 2018), Embase (1988 to June 2018), Education Resource Information Center (ERIC; EBSCOhost; 1966 to June 2018), PsycINFO (Ovid 1806 to June 2018), and Google Scholar. We also searched clinical trial registers and handsearched references of topic-related systematic reviews and the included studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and cluster RCTs (C-RCTs) involving the parents of school-aged children who were part of the general population with no known risk factors (universal interventions), were at elevated risk of alcohol use or problem drinking (selective interventions), or were already consuming alcohol (indicated interventions). Psychosocial or educational interventions involving parents with or without involvement of children were compared with no intervention, or with alternate (e.g. child only) interventions, allowing experimental isolation of parent components. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. MAIN RESULTS: We included 46 studies (39,822 participants), with 27 classified as universal, 12 as selective, and seven as indicated. We performed meta-analyses according to outcome, including studies reporting on the prevalence, frequency, or volume of alcohol use. The overall quality of evidence was low or very low, and there was high, unexplained heterogeneity.Upon comparing any family intervention to no intervention/standard care, we found no intervention effect on the prevalence (standardised mean difference (SMD) 0.00, 95% confidence interval (CI) -0.08 to 0.08; studies = 12; participants = 7490; I² = 57%; low-quality evidence) or frequency (SMD -0.31, 95% CI -0.83 to 0.21; studies = 8; participants = 1835; I² = 96%; very low-quality evidence) of alcohol use in comparison with no intervention/standard care. The effect of any parent/family interventions on alcohol consumption volume compared with no intervention/standard care was very small (SMD -0.14, 95% CI -0.27 to 0.00; studies = 5; participants = 1825; I² = 42%; low-quality evidence).When comparing parent/family and adolescent interventions versus interventions with young people alone, we found no difference in alcohol use prevalence (SMD -0.39, 95% CI -0.91 to 0.14; studies = 4; participants = 5640; I² = 99%; very low-quality evidence) or frequency (SMD -0.16, 95% CI -0.42 to 0.09; studies = 4; participants = 915; I² = 73%; very low-quality evidence). For this comparison, no trials reporting on the volume of alcohol use could be pooled in meta-analysis.In general, the results remained consistent in separate subgroup analyses of universal, selective, and indicated interventions. No adverse effects were reported. AUTHORS' CONCLUSIONS: The results of this review indicate that there are no clear benefits of family-based programmes for alcohol use among young people. Patterns differ slightly across outcomes, but overall, the variation, heterogeneity, and number of analyses performed preclude any conclusions about intervention effects. Additional independent studies are required to strengthen the evidence and clarify the marginal effects observed.

Severe Disseminated Necrotizing and Granulomatous Lymphadenitis and Encephalitis in a Dog Due to Sporotrichum pruinosum (Teleomorph: Phanerochaete chrysosporium).

A 9-year-old female mixed breed dog presented for an acute onset of anorexia, vomiting, and cough. Initial examination and diagnostics revealed a large multilobular cranial mediastinal mass with unidentified fungal organisms on cytology. The disease progressed in spite of therapy until the dog was euthanized 8 months later. Gross necropsy findings were a large multilobular intrathoracic mass, mild pleuritis, and generalized lymphadenopathy. Histologic evaluation showed granulomatous inflammation and necrosis with numerous 20- to 70-micron, periodic acid-Schiff- and Gomori methenamine silver-positive spherules effacing lymph node parenchyma, as well as severe inflammation within the midbrain. Endosporulation was a common finding, and large numbers of fungal hyphae were also present in affected areas. Ribosomal RNA gene sequencing found 100% identity to published sequences of Phanerochaete chrysosporium, the teleomorph form of Sporotrichum pruinosum. This is the first published report of disease caused by natural infection with this basidiomycete organism in animals.

Microvascular Replantation Following Facial Dog Bites in Children: Systematic Review and Management Algorithm.

BACKGROUND: Pediatric dog bite injuries account for 1% of emergency department visits per year and represent an underrecognized and underreported public health problem. Reconstructive surgery is frequently utilized, and in the most extreme injuries, microvascular replantation may be considered. We sought to systematically review the available literature on microvascular replantation after facial dog bite injuries in children, with particular attention to perioperative morbidity and long-term follow-up. METHODS: We reviewed a case of microvascular replantation after a facial dog bite injury in a child from our own institution and conducted a systematic literature search to identify other similar reports. Clinical variables were collected from the reported cases, and descriptive statistics were calculated. A management algorithm was developed from the reviewed published experience. RESULTS: We report the youngest child to date in the literature to undergo replantation after a facial dog bite injury. Nineteen other cases were found involving children aged 18 months to 17 years, with follow-up ranging from 2 weeks to 28 years. Anastomosis techniques varied considerably and included both an artery and vein in only 9 (47%) of 19 cases. Venous congestion was nearly universal, and multimodal techniques were used until native venous outflow was reestablished. Blood transfusion was common, but intensive care unit utilization was not frequently reported. Long-term outcomes were excellent, with growth of the replanted part and recovery of function; however, minor revision procedures were common. CONCLUSIONS: Microvascular replantation following facial dog bite amputation injuries in the pediatric population is the ultimate step in the reconstructive ladder. Strong consideration should be given to microvascular exploration with involvement of large or whole segments of the lip, nose, or ear; however, parents should be counseled extensively regarding the known morbidity of replantation surgery. With meticulous surgical technique and careful postoperative care, replantation after facial dog bite amputation injuries may successfully achieve dramatic and lasting results for pediatric patients.

A systematic review and meta-analysis of moderate-to-vigorous physical activity levels in secondary school physical education lessons.

BACKGROUND: Schools play an important role in physical activity promotion for adolescents. The systematic review aimed to determine the proportion of secondary (middle and high) school physical education (PE) lesson time that students spend in moderate to vigorous physical activity (MVPA), and to assess if MVPA was moderated by school level (middle and high school), type of physical activity measurement and type of PE activities. METHODS: A systematic search of nine electronic databases was conducted (PROSPERO2014:CRD42014009649). Studies were eligible if they were published between 2005 and 2014; written in English; assessed MVPA in PE lessons of secondary (middle and high) school students; and used a quantitative MVPA measure (i.e., accelerometry, heart rate monitoring, pedometers or observational measures). Two reviewers examined the retrieved articles, assessed risk of bias, and performed data extraction. Random effects meta-analysis was used to calculate a pooled estimate of the percent of PE lesson time spent in MVPA and to assess moderator effects where data allowed. RESULTS: The search yielded 5,132 potentially relevant articles; 28 articles representing 25 studies (7 middle and 18 high school) from seven countries were included. Twelve studies measured MVPA through observational measures, seven used accelerometers, five used heart rate monitors and four used pedometers (including three studies using a mix of measures). Meta-analysis of 15 studies found that overall, students spent a mean (95% CI) of 40.5% (34.8-46.2%) of PE in MVPA. Middle school students spent 48.6% (41.3-55.9%) of the lesson in MVPA (n = 5 studies) and high school students 35.9% (28.3-43.6%) (n = 10 studies). Studies measuring MVPA using accelerometers (n = 5) showed that students spent 34.7% (25.1-44.4%) of the lesson in MVPA, while 44.4% (38.3-50.5%) was found for lessons assessed via observation (n = 9), 43.1% (24.3-61.9%) of the lesson for a heart rate based study, and 35.9% (31.0-40.8%) for a pedometer-measured study. CONCLUSIONS: The proportion of PE spent in MVPA (40.5%) is below the US Centre for Disease Control and Prevention and the UK Associations for Physical Education recommendation of 50%. Findings differed according to the method of MVPA assessment. Additional strategies and intervention research are needed to build more active lesson time in PE.

Undergraduate Rigor Scores: Do They Predict Achievement in Veterinary School?

The relations between potential indicators of undergraduate rigor and subsequent achievement in professional school are not clear; some studies have shown that greater undergraduate selectivity is associated with greater achievement in medical science programs, while others have not. We sought to determine the extent to which indicators of undergraduate rigor were associated with achievement in veterinary school. Participants were graduates from three cohorts. The predictors were undergraduate GPA (UGPA), plus five rigor scores-degree or number of undergraduate credits, number of honors courses, number of withdrawals from or repeats of prerequisite science courses, number of part-time semesters, and ratio of community college credits to total college credits. The outcomes were the veterinary medicine cumulative GPA (CVM GPA), Qualifying Exam scores, and North American Veterinary Licensing Exam scores. Using correlations corrected for range restriction, we regressed each outcome on the five rigor scores and UGPA for each of the three graduating cohorts. In most cases, indicators of undergraduate rigor did not predict subsequent achievement in veterinary school; however, in two comparisons, number of honors courses taken as an undergraduate predicted subsequent achievement. UGPA, as expected, predicted CVM GPA. Admissions committees may want to reevaluate whether they include undergraduate rigor when considering admission to their programs, with the caveat that our findings are specific to our institution and are not generalizable.

A systematic review and meta-analysis of moderate-to-vigorous physical activity levels in elementary school physical education lessons.

OBJECTIVE: To examine elementary school students' moderate-to-vigorous physical activity (MVPA) levels during physical education (PE) lessons. METHODS: A systematic search of nine electronic databases was conducted (PROSPERO2014:CRD42014009649). Studies were eligible if they were in English; published between 2005-April 2014; assessed MVPA levels in PE lessons of elementary school children (aged four-12years); and used an objective MVPA measure. Two reviewers retrieved articles, assessed risk of bias, and performed data extraction. The findings were synthesised using a meta-analysis. RESULTS: The search yielded 5132 articles. Thirteen studies from nine countries met the inclusion criteria. Eight studies measured MVPA through observational measures, five used accelerometry and one used heart rate monitoring. The percentage of PE lesson time spent in MVPA ranged between 11.4-88.5%. Meta-analysis of seven studies (4 direct observations; 4 accelerometers) found that children spent a mean (95% CI) 44.8 (28.2-61.4)% of PE lesson time in MVPA. When measured using direct observation and accelerometers, children spent 57.6 (47.3-68.2) and 32.6 (5.9-59.3)% of PE lesson time in MVPA, respectively. The review has limitations; the search strategy was restricted to studies in English; theses, dissertations and conference abstracts were excluded; and six studies that provided insufficient data were excluded from the meta-analysis. CONCLUSION: MVPA levels during elementary school PE lessons do not meet the United States Centre for Disease Control and Prevention and the United Kingdom's Association of Physical Education recommendation (50% of lesson time), but is higher than estimated in the previous review (34.2%). Interventions to increase MVPA in PE lessons are needed.

Strategies to improve the implementation of healthy eating, physical activity and obesity prevention policies, practices or programmes within childcare services.

BACKGROUND: Despite the existence of effective interventions and best-practice guideline recommendations for childcare services to implement policies, practices and programmes to promote child healthy eating, physical activity and prevent unhealthy weight gain, many services fail to do so. OBJECTIVES: The primary aim of the review was to examine the effectiveness of strategies aimed at improving the implementation of policies, practices or programmes by childcare services that promote child healthy eating, physical activity and/or obesity prevention. The secondary aims of the review were to:1. describe the impact of such strategies on childcare service staff knowledge, skills or attitudes;2. describe the cost or cost-effectiveness of such strategies;3. describe any adverse effects of such strategies on childcare services, service staff or children;4. examine the effect of such strategies on child diet, physical activity or weight status. SEARCH METHODS: We searched the following electronic databases on 3 August 2015: the Cochrane Central Register of Controlled trials (CENTRAL), MEDLINE, MEDLINE In Process, EMBASE, PsycINFO, ERIC, CINAHL and SCOPUS. We also searched reference lists of included trials, handsearched two international implementation science journals and searched the World Health Organization International Clinical Trials Registry Platform (www.who.int/ictrp/) and ClinicalTrials.gov (www.clinicaltrials.gov). SELECTION CRITERIA: We included any study (randomised or non-randomised) with a parallel control group that compared any strategy to improve the implementation of a healthy eating, physical activity or obesity prevention policy, practice or programme by staff of centre-based childcare services to no intervention, 'usual' practice or an alternative strategy. DATA COLLECTION AND ANALYSIS: The review authors independently screened abstracts and titles, extracted trial data and assessed risk of bias in pairs; we resolved discrepancies via consensus. Heterogeneity across studies precluded pooling of data and undertaking quantitative assessment via meta-analysis. However, we narratively synthesised the trial findings by describing the effect size of the primary outcome measure for policy or practice implementation (or the median of such measures where a single primary outcome was not stated). MAIN RESULTS: We identified 10 trials as eligible and included them in the review. The trials sought to improve the implementation of policies and practices targeting healthy eating (two trials), physical activity (two trials) or both healthy eating and physical activity (six trials). Collectively the implementation strategies tested in the 10 trials included educational materials, educational meetings, audit and feedback, opinion leaders, small incentives or grants, educational outreach visits or academic detailing. A total of 1053 childcare services participated across all trials. Of the 10 trials, eight examined implementation strategies versus a usual practice control and two compared alternative implementation strategies. There was considerable study heterogeneity. We judged all studies as having high risk of bias for at least one domain.It is uncertain whether the strategies tested improved the implementation of policies, practices or programmes that promote child healthy eating, physical activity and/or obesity prevention. No intervention improved the implementation of all policies and practices targeted by the implementation strategies relative to a comparison group. Of the eight trials that compared an implementation strategy to usual practice or a no intervention control, however, seven reported improvements in the implementation of at least one of the targeted policies or practices relative to control. For these trials the effect on the primary implementation outcome was as follows: among the three trials that reported score-based measures of implementation the scores ranged from 1 to 5.1; across four trials reporting the proportion of staff or services implementing a specific policy or practice this ranged from 0% to 9.5%; and in three trials reporting the time (per day or week) staff or services spent implementing a policy or practice this ranged from 4.3 minutes to 7.7 minutes. The review findings also indicate that is it uncertain whether such interventions improve childcare service staff knowledge or attitudes (two trials), child physical activity (two trials), child weight status (two trials) or child diet (one trial). None of the included trials reported on the cost or cost-effectiveness of the intervention. One trial assessed the adverse effects of a physical activity intervention and found no difference in rates of child injury between groups. For all review outcomes, we rated the quality of the evidence as very low. The primary limitation of the review was the lack of conventional terminology in implementation science, which may have resulted in potentially relevant studies failing to be identified based on the search terms used in this review. AUTHORS' CONCLUSIONS: Current research provides weak and inconsistent evidence of the effectiveness of such strategies in improving the implementation of policies and practices, childcare service staff knowledge or attitudes, or child diet, physical activity or weight status. Further research in the field is required.

Thermocrinis jamiesonii sp. nov., a thiosulfate-oxidizing, autotropic thermophile isolated from a geothermal spring.

An obligately thermophilic, chemolithotrophic, microaerophilic bacterium, designated strain GBS1T, was isolated from the water column of Great Boiling Spring, Nevada, USA. Thiosulfate was required for growth. Although capable of autotrophy, growth of GBS1T was enhanced in the presence of acetate, peptone or Casamino acids. Growth occurred at 70-85 °C with an optimum at 80 °C, at pH 6.50-7.75 with an optimum at pH 7.25, with 0.5-8 % oxygen with an optimum at 1-2 % and with ≤ 200 mM NaCl. The doubling time under optimal growth conditions was 1.3 h, with a final mean cell density of 6.2 ± 0.5 × 107 cells ml- 1. Non-motile, rod-shaped cells 1.4-2.4 × 0.4-0.6 µm in size occurred singly or in pairs. The major cellular fatty acids (>5 % of the total) were C20 : 1ω9c, C18 : 0, C16 : 0 and C20 : 0. Phylogenetic analysis of the GBS1T 16S rRNA gene sequence indicated an affiliation with Thermocrinis ruber and other species of the genus Thermocrinis, but determination of 16S rRNA gene sequence similarity ( ≤ 97.10 %) and in silico estimated DNA-DNA hybridization values ( ≤ 18.4 %) with the type strains of recognized Thermocrinis species indicate that the novel strain is distinct from described species. Based on phenotypic, genotypic and phylogenetic characteristics, a novel species, Thermocrinis jamiesonii sp. nov., is proposed, with GBS1T ( = JCM 19133T = DSM 27162T) as the type strain.

RETROSPECTIVE EVALUATION OF CASES OF NEOPLASIA IN A CAPTIVE POPULATION OF EGYPTIAN FRUIT BATS (ROUSETTUS AEGYPTIACUS).

Reports of neoplasia in Chiroptera species are rare. (6, 10) This retrospective study describes five types of neoplasia identified within a captive population of male Egyptian fruit bats (Rousettus aegyptiacus) housed in a zoo from 2004 through November of 2014. Tumor types identified include fibrosarcoma, cutaneous lymphoma, benign focal bronchioloalveolar neoplasm, anaplastic sarcoma, and sebaceous epithelioma. To the author's knowledge, aside from a recent report of focal brochioloalveolar adenoma, (8) these tumor types have not previously been described in the Rousettus species, nor in chiropterans in general. Based upon these findings and other recent publications regarding R. aegyptiacus, neoplasia does appear to be a significant cause of morbidity and mortality in captive members of this megachiropterid species.

Kallotenue papyrolyticum gen. nov., sp. nov., a cellulolytic and filamentous thermophile that represents a novel lineage (Kallotenuales ord. nov., Kallotenuaceae fam. nov.) within the class Chloroflexia.

Several closely related, thermophilic and cellulolytic bacterial strains, designated JKG1(T), JKG2, JKG3, JKG4 and JKG5, were isolated from a cellulolytic enrichment (corn stover) incubated in the water column of Great Boiling Spring, NV. Strain JKG1(T) had cells of diameter 0.7-0.9 µm and length ~2.0 µm that formed non-branched, multicellular filaments reaching >300 µm. Spores were not formed and dense liquid cultures were red. The temperature range for growth was 45-65 °C, with an optimum of 55 °C. The pH range for growth was pH 5.6-9.0, with an optimum of pH 7.5. JKG1(T) grew as an aerobic heterotroph, utilizing glucose, sucrose, xylose, arabinose, cellobiose, CM-cellulose, filter paper, microcrystalline cellulose, xylan, starch, Casamino acids, tryptone, peptone, yeast extract, acetate, citrate, lactate, pyruvate and glycerol as sole carbon sources, and was not observed to photosynthesize. The cells stained Gram-negative. Phylogenetic analysis using 16S rRNA gene sequences placed the new isolates in the class Chloroflexia, but distant from other cultivated members, with the highest sequence identity of 82.5 % to Roseiflexus castenholzii. The major quinone was menaquinone-9; no ubiquinones were detected. The major cellular fatty acids (>5 %) were C18 : 0, anteiso-C17 : 0, iso-C18 : 0, iso-C17 : 0, C16 : 0, iso-C16 : 0 and C17 : 0. The peptidoglycan amino acids were alanine, ornithine, glutamic acid, serine and asparagine. Whole-cell sugars included mannose, rhamnose, glucose, galactose, ribose, arabinose and xylose. Morphological, phylogenetic and chemotaxonomic results suggest that JKG1(T) is representative of a new lineage within the class Chloroflexia, which we propose to designate Kallotenue papyrolyticum gen. nov., sp. nov., Kallotenuaceae fam. nov., Kallotenuales ord. nov. The type strain of Kallotenue papyrolyticum gen. nov., sp. nov. is JKG1(T) ( = DSM 26889(T) = JCM 19132(T)).

Predictors of employer satisfaction: technical and non-technical skills.

Employers of 2007-2009 graduates from Iowa State University College of Veterinary Medicine were asked to respond to a survey regarding their overall satisfaction with their new employees as well as their new employees' preparation in several technical and non-technical skill areas. Seventy-five responses contained complete data and were used in the analysis. Four technical skill areas (data collection, data interpretation, planning, and taking action) and five non-technical skill areas (interpersonal skills, ability to deal with legal issues, business skills, making referrals, and problem solving) were identified. All of the skill area subscales listed above had appropriate reliability (Cronbach's alpha>0.70) and were positively and significantly correlated with overall employer satisfaction. Results of two simultaneous regression analyses indicated that of the four technical skill areas, taking action is the most salient predictor of employer satisfaction. Of the five non-technical skill areas, interpersonal skills, business skills, making referrals, and problem solving were the most important skills in predicting employer satisfaction. Hierarchical regression analysis revealed that all technical skills explained 25% of the variation in employer satisfaction; non-technical skills explained an additional 42% of the variation in employer satisfaction.

Test of recrudescence hypothesis for overwintering of eastern equine encephalomyelitis virus in gray catbirds.

Eastern equine encephalitis virus (EEEV; family Togaviridae, genus Alphavirus) epizootics are infrequent, but they can lead to high mortality in infected horses and humans. Despite the importance of EEEV to human and animal health, little is known about how the virus overwinters and reinitiates transmission each spring, particularly in temperate regions where infected adult mosquitoes are unlikely to survive through the winter. One hypothesis to explain the mechanism by which this virus persists from year to year is the spring recrudescence of latent virus in avian reservoir hosts. In this study, we tested the recrudescence hypothesis with gray catbirds (Dumatella carolinensis) captured in northern Ohio (July-August 2007). Birds were experimentally infected with EEEV on 1 October 2007. In January 2008, they were then exposed to exogenous testosterone and/or extended photoperiod to initiate reactivation of latent EEEV infection. All birds became viremic with EEEV, with mean viremia of 6.0 log10 plaque-forming units/ml serum occurring at 1 d postinoculation. One male in the testosterone, long-day treatment group had EEEV viral RNA in a cloacal swab collected on 18 January 2008. Otherwise, no other catbirds exhibited reactivated infections in cloacal swabs or blood. Antibody titers fluctuated over the course of the study, with lowest titers observed in January 2008, which corresponded with the lowest mean weight of the birds. No EEEV viral RNA was detected in the blood, kidney, spleen, brain, liver, and lower intestine upon necropsy at 19 wk postinfection.

Improved efficacy of a gene optimised adenovirus-based vaccine for venezuelan equine encephalitis virus.

BACKGROUND: Optimisation of genes has been shown to be beneficial for expression of proteins in a range of applications. Optimisation has increased protein expression levels through improved codon usage of the genes and an increase in levels of messenger RNA. We have applied this to an adenovirus (ad)-based vaccine encoding structural proteins (E3-E2-6K) of Venezuelan equine encephalitis virus (VEEV). RESULTS: Following administration of this vaccine to Balb/c mice, an approximately ten-fold increase in antibody response was elicited and increased protective efficacy compared to an ad-based vaccine containing non-optimised genes was observed after challenge. CONCLUSION: This study, in which the utility of optimising genes encoding the structural proteins of VEEV is demonstrated for the first time, informs us that including optimised genes in gene-based vaccines for VEEV is essential to obtain maximum immunogenicity and protective efficacy.

Vitamin D deficiency and insufficiency in children with tuberculosis.

We examined the prevalence of vitamin D deficiency and insufficiency in children attending our tuberculosis (TB) clinic during a 2-year period. Sixty-four patients were included with active TB (n = 26) or latent TB infection (n = 38). Eighty-six percent (n = 55) were either vitamin D deficient (serum 25-hydroxyvitamin D <20 nmol/L) or insufficient (serum 25-hydroxyvitamin D <75 nmol/L). Only 1 child with active TB was vitamin D replete.

Peer assessment of a final-year capstone experience for formative evaluation of a pathology curriculum.

In spring of 2005, the authors implemented and evaluated a process at the Iowa State University College of Veterinary Medicine in which third-year students evaluated fourth-year students' performances on an advanced case-analysis assignment. This assignment, called the case correlation assignment, required a thorough integration and explanation of all ante- and post-mortem data for a specific hospital patient. Using a 21-point rubric, the necropsy course instructor and third-year students rated these assignments. Fourth-year students' performances on this assignment were used as an indicator of the success of the pathology curriculum. The authors evaluated the assessment process for feasibility, reliability, and validity. Many-facet Rasch analysis was used to determine item, case, and rater agreement. The assessment process produced good agreement among items and cases (VM4 student competence). Furthermore, most third-year students were able to reliably rate the case correlation assignments with no special training. The evaluation process was cost effective and occurred in the context of regular course assignments, thereby making it feasible. A case can be made that the overall process provides a valid measure of the pathology program's success in preparing students in the area of veterinary pathology.

The Physical Activity 4 Everyone Cluster Randomized Trial: 2-Year Outcomes of a School Physical Activity Intervention Among Adolescents.

INTRODUCTION: Few interventions have been successful in reducing the physical activity decline typically observed among adolescents. The aim of this paper is to report the 24-month effectiveness of a multicomponent school-based intervention (Physical Activity 4 Everyone) in reducing the decline in moderate to vigorous physical activity (MVPA) among secondary school students in disadvantaged areas of New South Wales, Australia. STUDY DESIGN: A cluster RCT was conducted in five intervention and five control schools with follow-up measures taken at 24 months post-randomization. SETTING/PARTICIPANTS: The trial was undertaken within secondary schools located in disadvantaged communities in New South Wales, Australia. INTERVENTION: A multicomponent school-based intervention based on the Health Promoting Schools Framework was implemented. The intervention consisted of seven physical activity promotion strategies that targeted the curriculum (teaching strategies to increase physical activity in physical education lessons, student physical activity plans, and modification of school sport program); school environment (recess/lunchtime activities, school physical activity policy); parents (parent newsletters); and community (community physical activity provider promotion). Six additional strategies supported school implementation of the physical activity intervention strategies. MAIN OUTCOME MEASURE: Minutes per day spent in MVPA, objectively measured by accelerometer. RESULTS: Participants (N=1,150, 49% male) were a cohort of students aged 12 years (Grade 7) at baseline (March-June 2012) and 14 years (Grade 9) at follow-up (March-July 2014). At 24-month follow-up, there were significant effects in favor of the intervention group for daily minutes of MVPA. The adjusted mean difference in change in daily MVPA between groups was 7.0 minutes (95% CI=2.7, 11.4, p<0.002) (analysis conducted December 2014-February 2015). Sensitivity analyses based on multiple imputation were consistent with the main analysis (6.0 minutes, 95% CI=0.6, 11.3, p<0.031). CONCLUSIONS: The intervention was effective in increasing adolescents' minutes of MVPA, suggesting that implementation of the intervention by disadvantaged schools has the potential to slow the decline in physical activity.

Gene content and growth experiments demonstrate broad metabolic capacity, including starch hydrolysis, thiosulfate oxidation, arsenite oxidation, incomplete denitrification, and polysulfide reduction.

Surveillance of amyloidosis and other diseases at necropsy in captive trumpeter swans (Cygnus buccinator).

The purpose of this study was to characterize the incidence and diagnostic features of amyloidosis and other diseases found at necropsy in captive trumpeter swans (Cygnus buccinator). A search of Iowa State University's Department of Veterinary Pathology and Veterinary Diagnostic Laboratory databases yielded 31 trumpeter swan (C. buccinator) necropsy cases from captive swans in protected habitats. Eleven of the 31 birds had amyloid deposition most commonly in the spleen (8 of 11), liver (7 of 11), and kidney (6 of 11) and less often in the pancreas (2 of 11) and adrenal gland (2 of 11). Amyloid deposition effaced normal tissue with adjacent necrosis and hemorrhage in severe cases. Amyloidosis was most often diagnosed in February and March. Other disease diagnoses in the trumpeter swans included aspergillosis (5 of 31, 16%); bacterial infection (5 of 31, 16%); lead toxicosis (3 of 31, 10%); gout (2 of 31, 6%); parasitic infection (2 of 31, 6%); vitamin E deficiency (1 of 31, 3%); trauma (1 of 31, 3%); and ventricular foreign body (1 of 31, 3%). Histopathologic, toxicologic, and microbiologic analyses did not define an etiologic diagnosis in the deaths of 9 trumpeter swans. In these cases, necropsy lesions included emaciation (5 of 9), enteritis (1 of 9), pulmonary hemorrhage (1 of 9), and no lesions (3 of 9). The number of trumpeter swan case submissions was greatest in January and February. This study provides a reference for veterinary diagnosticians concerning incidence and diagnostic features of amyloidosis and other diseases in captive trumpeter swans of the midwestern United States.

Isolation of diverse members of the Aquificales from geothermal springs in Tengchong, China.

The order Aquificales (phylum Aquificae) consists of thermophilic and hyperthermophilic bacteria that are prominent in many geothermal systems, including those in Tengchong, Yunnan Province, China. However, Aquificales have not previously been isolated from Tengchong. We isolated five strains of Aquificales from diverse springs (temperature 45.2-83.3°C and pH 2.6-9.1) in the Rehai Geothermal Field from sites in which Aquificales were abundant. Phylogenetic analysis showed that four of the strains belong to the genera Hydrogenobacter, Hydrogenobaculum, and Sulfurihydrogenibium, including strains distant enough to likely justify new species of Hydrogenobacter and Hydrogenobaculum. The additional strain may represent a new genus in the Hydrogenothermaceae. All strains were capable of aerobic respiration under microaerophilic conditions; however, they had variable capacity for chemolithotrophic oxidation of hydrogen and sulfur compounds and nitrate reduction.
