Abstract: Adenoviruses are well known causes of respiratory illness in children. Long term sequelae reported with types 3, 7, and 21 include bronchiolitis obliterans, bronchiectasis, and the hyperlucent lung or McLeod syndrome. Twenty children admitted to hospital with adenovirus type 7 pneumonia between 1960 and 1978 were studied and compared with 20 controls admitted during the same period with adenovirus type 7 upper respiratory tract infections. Sixty five per cent of the pneumonia group had developed evidence of airways obstruction compared with 10% of controls. Young age at the time of pneumonia and a 'measles-like' illness before its onset increase the chance of developing long term pulmonary function abnormalities. Sex and family history of smoking or atopy do not influence outcome.

Abstract: Long-term (1940–1970) flowering synchrony of Eucalyptus leucoxylon ssp. pruinosa (F.Muell. ex Miq.) Boland, E. microcarpa (Maiden) Maiden, E. polyanthemos ssp. vestita L.A.S.Johnson & K.D.Hill and E. tricarpa (L.A.S.Johnson) L.A.S.Johnson & K.D.Hill was quantified at the tree level. The least synchronous grouping was E. polyanthemos and E. microcarpa (0.06), with flowering overlap occurring in only 5 of the 30 years. The species with the most synchronous flowering were E. leucoxylon and E. tricarpa (0.62): flowering overlapped in 24 of the 30 years. Synchrony in the 1996–1997 flowering season was found to be 'typical': overlap among all species pairs and groupings was within the range delineated by the long-term data (e.g. the synchrony of 0.53 for E. leucoxylon and E. polyanthemos was similar to its mean long-term overlap of 0.51). In idual species flowered synchronously, both within (0.82–0.92) and across sites (0.81– 0.93). Flowering did not occur in any of the monitored trees during 1997–1998. Long-term synchrony values assist in quantifying the likelihood of hybridisation between species, and provide a baseline which may assist in detecting recent or future changes.

Abstract: Dependence in meta-analytic models can happen due to the same collected data or from the same researchers. The hierarchical Bayesian linear model in a meta-analysis that allows dependence in effect sizes is investigated in this paper. The interested parameters on the hierarchical Bayesian linear dependence (HBLD) model which was developed using the Bayesian techniques will then be estimated. The joint posterior distribution of all parameters for the hierarchical Bayesian linear dependence (HBLD) model is obtained by applying the Gibbs s ling algorithm. Furthermore, in order to measure the robustness of the HBLD model, the sensitivity analysis is conducted using a different prior distribution on the model. This is carried out by applying the Metropolis within the Gibbs algorithm. The simulation study is performed for the estimation of all parameters in the model. The results show that the obtained estimated parameters are close to the true parameters, indicating the consistency of the parameters for the model. The model is also not sensitive because of the changing prior distribution which shows the robustness of the model. A case study, to assess the effects of native-language vocabulary aids on second language reading, is conducted successfully in testing the parameters of the models.

Abstract: There is substantial evidence of climate-related shifts to the timing of avian migration. Although spring arrival has generally advanced, variable species responses and geographical biases in data collection make it difficult to generalise patterns. We advance previous studies by using novel multivariate statistical techniques to explore complex relationships between phenological trends, climate indices and species traits. Using 145 datasets for 52 bird species, we assess trends in first arrival date (FAD), last departure date (LDD) and timing of peak abundance at multiple Australian locations. Strong seasonal patterns were found, i.e. spring phenological events were more likely to significantly advance, while significant advances and delays occurred in other seasons. However, across all significant trends, the magnitude of delays exceeded that of advances, particularly for FAD (+22.3 and -9.6 days/decade, respectively). Geographic variations were found, with greater advances in FAD and LDD, in south-eastern Australia than in the north and west. We identified four species clusters that differed with respect to species traits and climate drivers. Species within bird clusters responded in similar ways to local climate variables, particularly the number of raindays and rainfall. The strength of phenological trends was more strongly related to local climate variables than to broad-scale drivers (Southern Oscillation Index), highlighting the importance of precipitation as a driver of movement in Australian birds.

Abstract: Abstract Background Vitamin C (ascorbic acid) is a micronutrient imperative for many bodily functions, with research revealing its functional support of leukocytes. The purpose of this meta-analysis was to determine the effects of surgery on leukocyte vitamin C concentrations by assessing the amount and longevity of post-operative leukocyte vitamin C change. Data Sources We searched the PUBMED, SCOPUS, SciSearch and the Cochrane Library databases for relevant research papers. Studies were included until January 2022, with no time limits. Studies that reported means and standard deviations of leukocyte/buffer layer vitamin C concentrations before and after surgery were included into the meta-analysis. The meta-analysis comprised of eight studies. Results Seven studies (which included 8 in idual studies) were included into our meta-analysis. Combined data from the meta-analysis displayed a significant depletion in mean leukocyte vitamin C concentrations during the first 24 hours following the surgery by a mean of 5.37 µg/108 (32.3%) (CI = -6.35, -4.40) (n = 6, p 0.001) and during the first post-operative week by 4.43 µg/108 (23%) (-7.27, -1.58) (n = 7, p 0.001). However, this depletion was followed by an uprise in mean ascorbic acid leukocyte concentrations of 0.93 µg/108 (4.8%) (-0.79, 2.66) (n = 6, p = 0.29) at 7 days (or beyond) post-operatively. Conclusion Significant post-operative leukocyte vitamin C depletions were particularly observed during the first post-operative week. Further research is required to validate the observed results and to determine whether the observed depletions may be linked to compromised immunological function and pathophysiologies that arise during the post-operative period.

Abstract: A double-blind controlled trial of azathioprine (2 mg · kg−1 · day−1) was conducted with 49 patients aged 2–20 yr (mean 10.8 yr) who had newly diagnosed type I (insulin-dependent) diabetes. Patients were randomly assigned to receive either azathioprine (n = 24) or placebo (n = 25) for 12 mo, beginning within the 20 day period after diagnosis. Baseline clinical and metabolic characteristics did not differ between the two groups. No patient experienced complete remission, defined as restoration of normal carbohydrate tolerance without other treatment. Partial remission, defined as good metabolic control (hemoglobin A1c ≤7.9%, preprandial blood glucose ≤8 mM with an insulin dose of & .5 U. kg−1 · day1), occurred in 10 placebo (40%) and 7 azathioprine (29%) patients at 6 mo and in 4 placebo (16%) and 4 azathioprine (17%) patients at 12 mo (differences not significant). Fasting plasma C-peptide was significantly greater in the azathioprine-treated group at 3 and 6 mo, but this difference was not sustained. C-peptide responses to a standard meal and the frequency of islet cell and insulin antibodies did not differ between the two groups over the 12-mo period. Azathioprine caused no significant side effects. We conclude that in the dosage used, and despite early effects on endogenous insulin secretion, azathioprine alone does not influence the remission phase in children with newly diagnosed type I diabetes.

Abstract: The analysis of aggregate, or marginal, data for contingency tables is an increasingly important area of statistics, applied sciences and the social sciences. This is largely due to confidentiality issues arising from the imposition of government and corporate protection and data collection methods. The availability of only aggregate data makes it difficult to draw conclusions about the association between categorical variables at the in idual level. For data analysts, this issue is of growing concern, especially for those dealing with the aggregate analysis of a single 2 × 2 table or stratified 2 × 2 tables and lies in the field of ecological inference. As an alternative to ecological inference techniques, one may consider the aggregate association index (AAI) to obtain valuable information about the magnitude and direction of the association between two categorical variables of a single 2 × 2 table or stratified 2 × 2 tables given only the marginal totals. Conventionally, the AAI has been examined by considering $${\\mathrm{p}}_{11}$$ p 11 —the proportion of the s le that lies in the (1, 1)th cell of a given 2 × 2 table. However, the AAI can be expanded for other association indices. Therefore, a new generalisation of the original AAI is given here by reformulating and expanding the index so that it incorporates any linear transformation of $${\\mathrm{p}}_{11}$$ p 11 . This study shall consider the consistency of the AAI under the transformation by examining four classic association indices, namely the independence ratio, Pearson’s ratio, standardised residual and adjusted standardised residual, although others may be incorporated into this general framework. We will show how these indices can be utilised to examine the strength and direction of association given only the marginal totals. Therefore, this work enhances our understanding of the AAI and establishes its links with common association indices.

Abstract: The appearance of buds and development of fruits in 51 species of Eucalyptus L’Hér. were examined to determine whether bud and fruit volume had an influence on flowering. These variables exert an influence on eucalypt flowering as in iduals and as members within an umbel. Flowering earlier in the growing season is characteristic of species with large, in idual bud and fruit volume and those that have a large umbel volume. The number of buds and fruits in an umbel is influenced by volume of the in iduals. Development time of buds was longer in umbels which had a larger total volume. Bud and fruit umbel volume was positively correlated with the timing of bud appearance as was seed maturity with in idual fruit and fruit umbel volume. A threshold of bud and fruit volume was indicated below which seed maturity and time of flowering is not reflected by volume. Discriminant analysis used nine predictors to assign 80% (overall) of section members of Adnataria (91%), Bisectaria (60%), Maidenaria (67%) and Renantheria (87%) to their true groups. Across groups examination adduced the possibility of each group having a distinct bud development period and a discernible cessation of flowering. Five clusters were revealed whose members were significantly differentiated on seed maturity, section, in idual fruit volumes, bud and fruit umbel volumes. Factor analysis outlined four factors—buds, fruits, timing and development—which accounted for 78.9% of the variance.

Abstract: Self-Organising Map (SOM) clustering methods applied to the monthly and seasonal averaged flowering intensity records of eight Eucalypt species are shown to successfully quantify, visualise and model synchronisation of multivariate time series. The SOM algorithm converts complex, nonlinear relationships between high-dimensional data into simple networks and a map based on the most likely patterns in the multiplicity of time series that it trains. Monthly- and seasonal-based SOMs identified three synchronous species groups (clusters): E. camaldulensis, E. melliodora, E. polyanthemos E. goniocalyx, E. microcarpa, E. macrorhyncha and E. leucoxylon, E. tricarpa. The main factor in synchronisation (clustering) appears to be the season in which flowering commences. SOMs also identified the asynchronous relationship among the eight species. Hence, the likelihood of the production, or not, of hybrids between sympatric species is also identified. The SOM pattern-based correlation values mirror earlier synchrony statistics gleaned from Moran correlations obtained from the raw flowering records. Synchronisation of flowering is shown to be a complex mechanism that incorporates all the flowering characteristics: flowering duration, timing of peak flowering, of start and finishing of flowering, as well as possibly specific climate drivers for flowering. SOMs can accommodate for all this complexity and we advocate their use by phenologists and ecologists as a powerful, accessible and interpretable tool for visualisation and clustering of multivariate time series and for synchrony studies.

Abstract: In a prospective randomized controlled trial involving 470 arterial catheters in 470 children, we studied the effect of changing either the concentration or the flow rate of a heparin infusion. Although catheters tended to remain patent longer with a flow rate of 2 ml/h rather than 1 ml/h, the difference was not statistically significant. Increasing the heparin concentration from 1 to 5 U/ml significantly prolonged catheter patency.

Abstract: This study investigates the relationship between motor function and processing speed in preterm children. Processing speed was compared in 145 adolescents, born 25-41 weeks gestational age, utilizing tasks including differing motor demands. The influence of motor cortex excitability and functional motor skills on task performance was assessed. For tasks with motoric demands, differences in performance between preterm and term-born children were mediated by the relationship between gestational age, corticomotor excitability, and motor function. There were no differences in non-motor processing speed task performance between preterm and term-born children. Measures of processing speed may be confounded by a timed motor component.
