EARLY EXPERIENCE WITH CLINICAL INDICATORS IN SURGERY

ANZ JOURNAL OF SURGERY, Issue 6 2000
B. T. Collopy
Background: In 1997 a set of 53 clinical indicators developed by the Royal Australasian College of Surgeons (RACS) and the Australian Council on Healthcare Standards (ACHS) Care Evaluation Programme (CEP), was introduced into the ACHS Evaluation and Quality Improvement Programme (EQuIP). The clinical indicators covered 20 different conditions or procedures for eight specialty groups and were designed to act as flags to possible problems in surgical care. Methods: The development process took several years and included a literature review, field testing, and revision of the indicators prior to approval by the College council. In their first year 155 health-care organizations (HCO) addressed the indicators and this rose to 210 in 1998. Data were received from all states and both public and private facilities. Results: The collected data for 1997 and 1998 for some of the indicators revealed rates which were comparable with those reported in the international literature. For example, the rates of bile duct injury in laparoscopic cholecystectomy were 0.7 and 0.53%, respectively; the mortality rates for coronary artery graft surgery were 2.5 and 2.1%, respectively; the mortality rates after elective abdominal aortic aneurysm repair were 2.5 and 3.7%, respectively; and the post-tonsillectomy reactionary haemorrhage rates were 0.9 and 1.3%, respectively. Results for some indicators differed appreciably from other reports, flagging the need for further investigation; for example, the negative histology rates for appendectomy in children were 18.6 and 21.2%, respectively, and the rates for completeness of excision of malignant skin tumours were 90.7 and 90%, respectively. The significance of these figures, however, depends upon validation of the data and their reliability and reproducibility. Because reliability can be finally determined only at the hospital level they are of limited value for broader comparison. Conclusion: The process of review established for the indicator set has led to refinement of some indicators through improvement of definitions, and to a considerable reduction in the number of indicators to 29 (covering 18 procedures), for the second version of the indicators (which was introduced for use from January 1999). The clinical indicator programme, as it has with other disciplines, hopefully will provide a stimulus to the modification and improvement of surgical practice. Clinician ownership should enhance the collection of reliable data and hence their usefulness. [source]

Negotiating and managing partnership in primary care

HEALTH & SOCIAL CARE IN THE COMMUNITY, Issue 5 2001
Julie Charlesworth
Abstract In the UK public service organisations are increasingly working together in new partnerships, networks and alliances, largely stimulated by government legislation, which aims to encourage ,joined-up' policy-making. This is particularly prevalent in health-care where local government, health authorities and trusts, voluntary and community groups are extending existing, and developing new, forms of partnership, particularly around Health Improvement Programmes and new primary care organisations. This paper explores two main aspects of how these new interorganisational relationships are being developed and managed and is based on research conducted in one case study locality. First, the new structures of partnership in primary care are mapped out, together with discussion on why these particular patterns of relationship between statutory and voluntary sector organisations have emerged, exploring both centrally and locally determined influences. Secondly, the paper explores the tensions associated with working within new policy-making and management structures, and how the additional demands of audit, performance measurement and the sheer pace of change, pose a potential threat to the partnership process.

An Integrative Framework for Measuring the Extent to which Organizational Variables Influence the Success of Process Improvement Programmes

JOURNAL OF MANAGEMENT STUDIES, Issue 7 2005
Peter Lok
abstract Studies on the three types of process improvement programmes (Continuous Improvement, Reengineering and Benchmarking) have appeared many times in the literature. These studies suggest that certain organizational variables act as enablers and their presence or absence can significantly influence success rates. Such studies have tended to examine companies where a single programme has been implemented. In contrast, this paper examines a sample of companies who have experienced all three programmes. Our aim is to compare and contrast each programme's impact on firm performance and identify which organizational variables are common and which are programme-specific enablers of success. We build and test an integrative framework to support our analysis. Our study found that: (1) Reengineering delivered the greatest impact on performance; (2) executive commitment was needed to make this happen; (3) strategic alignment was the major influence on the success rate of Reengineering and Continuous Improvement programmes; and (4) employee empowerment was necessary for each programme to work effectively.

Biochemical Changes in Leaf Tissues of Taro [Colocasia esculenta L. (Schott)] Infected with Phytophthora colocasiae

JOURNAL OF PHYTOPATHOLOGY, Issue 3 2010
Manas Ranjan Sahoo
Abstract The changes in some biochemical parameters due to Phytophthora leaf blight infection were assessed in leaf tissues of one resistant (DP-25), two moderately resistant (Duradim and Jhankri) and one susceptible (N-118) genotypes of taro [Colocasia esculenta (L.) Schott]. Phytophthora spore suspension (15 000 spore/ml water) was sprayed onto the in vitro raised taro plantlets at 30 days after establishment in pots to induce disease. In comparison with the uninoculated leaves, blight infected leaves showed reduction in protein content and activity of nitrate reductase and increase in total soluble sugar, reducing sugar content and activities of acid phosphatase and alkaline phosphatase among the studied genotypes. Changes in biochemical parameters under induced blight stress as compared with uninoculated control were less in resistant genotypes than that in susceptible genotype. The deviations in biochemical contents were highest in susceptible genotype N-118. Based on the variations of above parameters under stress and non-stress control among the four tested genotypes, the overall pattern of changes was N-118 > Duradim > Jhankri > DP-25, which is in accordance with the pattern of increasing resistance. The resistant genotypes could be used for commercial cultivation and genetic improvement programme to develop resistant varieties to Phytophthora leaf blight disease. [source]

Combining ability and heterosis under pest epidemics in a broad-based global wheat-breeding population

PLANT BREEDING, Issue 3 2008
R. Ortiz
Abstract Wheat breeders rarely apply population improvement schemes or select parental sources according to combining ability and heterotic patterns. They rely on pedigree selection methods for breeding new cultivars. This experiment was undertaken to assess the advantages of using diallel crosses to define combining ability and understand heterosis in a broad-based wheat-breeding population across different environments affected by yellow rust. Sixty-four genotypes derived from a full diallel mating scheme were assessed for grain yield in two contrasting growing seasons at two locations for two consecutive years. Parental genotypes showed significant combining ability for grain yield that was affected by yellow rust and genotype-by-environment (GE) interactions, both of which affected heterosis for grain yield. Significant GE interactions suggested that decentralized selection for specific environments could maximize the use of this wheat germplasm. Cultivar effects and specific heterosis were the most important factors influencing grain yield. Some crosses capitalized on additive genetic variation for grain yield. This research shows the power of available quantitative breeding tools to help breeders choose parental sources in a population improvement programme. [source]

Genotypic and temperature effects on wheat grain yield and quality in a hot irrigated environment

PLANT BREEDING, Issue 4 2006
I. S. A. Tahir
Abstract High temperature influences both grain yield and end-use quality of wheat. The objectives of this study were to evaluate the performance of selected wheat genotypes under heat stress and to examine the effects of high temperatures during grain filling on grain yield and end-use quality parameters. Fifteen bread wheat genotypes in 2000/2001 and 18 genotypes in 2002/2003 were evaluated under the optimum and late-sowing conditions of the irrigated hot environment of the Gezira Research Farm, Wad Medani, Sudan. The genotypes comprised released varieties and elite lines from the Sudanese wheat improvement programme. Data collected included grain yield, grain weight and grain end-use quality including protein content, protein composition, SDS sedimentation values (SDSS) and gluten strength as determined by mixograph analyses. High temperatures significantly decreased grain yield by decreasing grain weight. Although genotypes exhibited variation in magnitude of response, results indicated that high temperature during grain filling increased both soluble and insoluble protein contents, SDSS, mixograph peak height (MPH) and the descending slope at 2 min past peak (MDS). In contrast, mixograph peak time (MPT) and the curve width at 2 min past peak (MCW) were significantly decreased. Flour protein correlated positively with SDSS, MPH and MDS and negatively with MCW. MPT correlated negatively with MDS and positively with MCW. Results indicate that high temperature increased both soluble and insoluble protein contents, SDSS and MPH, and hence the gluten strength, but decreased flour mixing time and tolerance and hence the dough elasticity. Variation observed among genotypes suggests that grain end-use quality could be improved under high temperature conditions utilizing the available variability; however, it might require evaluation under various growing conditions.

Unplanned extubation in a paediatric intensive care unit: impact of a quality improvement programme

ANAESTHESIA, Issue 11 2008
P. S. L. Da Silva
Summary Unplanned tracheal extubation is an important quality issue in current medical practice as it is a common occurrence in paediatric intensive care units. We have assessed the effectiveness of a continuous quality improvement programme in reducing the incidence of unplanned extubation over a 5-year period. After a 2-year baseline period, we developed action plans to address the issues identified. Following implementation of the programme, the overall incidence of unplanned extubation decreased from 2.9 unplanned extubations per 100 intubated patient days in the first year to 0.6 in the last year (p = 0.0001). This reduction was the result of a decrease in unplanned extubation in children younger than 2 years of age. Although mortality was similar to that of children who did not experience an unplanned extubation, those with an unplanned extubation had a significantly longer duration of mechanical ventilation, longer stay in the intensive care unit, and longer hospital stay. We found that the implementation of a continuous quality improvement programme is effective in reducing the overall incidence of unplanned extubations. [source]

Yield Responses of Barley to Leaf Stripe (Pyrenophora graminea) under Experimental Conditions in Southern Syria

JOURNAL OF PHYTOPATHOLOGY, Issue 8-9 2004
M. I. E. Arabi
Abstract The seed-borne pathogen, Pyrenophora graminea is the causal agent of barley leaf stripe disease. Field trials were undertaken to investigate the impact of leaf stripe on barley yield in two growing seasons in Southern Syria, by comparing plots with and without artificial inoculation. Ten barley cultivars originating from widely dispersed areas were used. The overall response to leaf stripe differed with the differences in susceptibility levels of the cultivars. Grain yield, the number of tillers, kernel weight and plant biomass decreased as disease severity increased. Diseased plants had fewer tillers, and as a consequence a reduced grain yield per plant. High yield losses resulted from leaf stripe in susceptible cultivars in Arrivate, Furat 1, WI2291 and Arabi Abiad with 44%, 50%, 73% and 92%, respectively. The cultivar Banteng had the best level of resistance to the disease, and is a candidate donor for resistance in future breeding programmes. As leaf stripe can dramatically reduce barley yields under favourable conditions, the disease should be considered by crop improvement programmes in Mediterranean and similar environments. [source]

Breast feeding very-low-birthweight infants at discharge: a multicentre study using WHO definitions

PAEDIATRIC & PERINATAL EPIDEMIOLOGY, Issue 6 2009
Riccardo Davanzo
Summary Human milk has several advantages in the nutrition of very-low-birthweight (VLBW) infants. However, there are limited data on breast feeding (BF) in neonatal intensive care units (NICU). The aim of this study was to identify a practical definition of BF rate in VLBW infants and to test its applicability and reproducibility in Italian NICUs. The study population included all VLBW infants discharged from 12 level 3 NICUs, over a 12-month period. Type of feeding was recorded according to the World Health Organisation (WHO) definition, with a 72-h recall period. We enrolled 594 VLBW infants. Mean birthweight was 1105 g (SD: 267), mean gestational age was 29.2 weeks (SD: 2.7) and mean length of stay in NICUs was 62.5 days (SD: 56.5). At discharge, 30.5% of VLBW infants were exclusively breast fed, 0.2% were predominantly breast fed, 23.8% were on complementary feeding and 45.5% were exclusively formula fed. A wide variability in BF rates was seen between centres. Among exclusively breast-fed VLBW infants, only 10% sucked directly and exclusively at the breast. WHO definitions can be used to assess type of feeding at discharge from NICUs. We speculate that common feeding definitions may allow both comparisons among different NICUs and ratings of quality improvement programmes. [source]

Somatic Embryogenesis in Leguminous Plants

PLANT BIOLOGY, Issue 2 2000
P. Lakshmanan
Abstract: This review examines recent advances in the induction and development of somatic embryos in leguminous plants. Emphasis has been given to identify the current trends and successful strategies for the establishment of somatic embryogenic systems, particularly in the economically important species. It appears that, in legumes, somatic embryogenesis can be realized relatively easily especially in young meristematic tissues such as immature embryos and developing leaves. In the majority of the species examined, chlorophenoxyacetic acids remained the most active inductive compounds; however, the new generation growth regulators such as thidiazuron are emerging as successful alternatives for high-frequency direct regeneration of somatic embryos, even from well differentiated explant tissues. Low-frequency embryo production, poor germination and conversion of somatic embryos into plantlets and somaclonal variation are the major impediments limiting the utility of somatic embryogenesis for biotechnological applications in legumes. These limitations, however, may be considerably reduced in the near future, as more newly developed growth regulators with specific morphogenic targets become available for experimentation. From the published data, it is apparent that more effort should be given to develop repetitive embryogenic systems with high frequency of germination and regeneration, since such systems will find immediate application in mass propagation and other crop improvement programmes. As our understanding of various morphogenic processes, including growth and differentiation of zygotic embryos, is fast expanding, it is conceivable that development of highly efficient somatic embryogenic systems with practical application can be anticipated, at least for the important leguminous crops, in the foreseeable future.

Utility of AFLP markers for the assessment of genetic diversity within Brassica nigra germplasm

PLANT BREEDING, Issue 1 2004
M. S. Negi
Abstract Genetic diversity of 18 Brassica nigra accessions was estimated using amplified fragment length polymorphism (AFLP) marker technology. Two B. rapa and two B. juncea accessions were selected as outliers in the study. Eight AFLP primer combinations generated a total of 426 bands, of which 79% were polymorphic. The UPGMA method was employed to construct a dendrogram based on the Jaccard's similarity coefficient. The accessions of B. rapa separated from those of B. nigra at a genetic similarity coefficient of 0.27 while those of B. juncea did so at 0.5. The genetic similarity coefficients within the B. nigra accessions ranged from 0.58 to 0.86. Based on these coefficients it was concluded that the B. nigra accessions show high levels of genetic variation. These results have significant implications in the crop improvement programmes for the agronomically important crop B. juncea, an amphidiploid of B. nigra and B. rapa. Two incorrectly labelled B. nigra accessions were also identified. These accessions were found to cluster with those of B. juncea accessions. This result demonstrates the great value of AFLP markers in the management of genebanks. [source]

Climate change and the characterization, breeding and conservation of animal genetic resources

ANIMAL GENETICS, Issue 2010
Irene Hoffmann
Summary Livestock production both contributes to and is affected by climate change. In addition to the physiological effects of higher temperatures on individual animals, the consequences of climate change are likely to include increased risk that geographically restricted rare breed populations will be badly affected by disturbances. Indirect effects may be felt via ecosystem changes that alter the distribution of animal diseases or affect the supply of feed. Breeding goals may have to be adjusted to account for higher temperatures, lower quality diets and greater disease challenge. Species and breeds that are well adapted to such conditions may become more widely used. Climate change mitigation strategies, in combination with ever increasing demand for food, may also have an impact on breed and species utilization, driving a shift towards monogastrics and breeds that are efficient converters of feed into meat, milk and eggs. This may lead to the neglect of the adaptation potential of local breeds in developing countries. Given the potential for significant future changes in production conditions and in the objectives of livestock production, it is essential that the value provided by animal genetic diversity is secured. This requires better characterization of breeds, production environments and associated knowledge; the compilation of more complete breed inventories; improved mechanisms to monitor and respond to threats to genetic diversity; more effective in situ and ex situ conservation measures; genetic improvement programmes targeting adaptive traits in high-output and performance traits in locally adapted breeds; increased support for developing countries in their management of animal genetic resources; and wider access to genetic resources and associated knowledge.

Evaluation of SPATA1 -associated markers for stallion fertility

ANIMAL GENETICS, Issue 4 2009
K. Giesecke
Summary Stallion fertility is an economically important trait because the use of artificial insemination is increasing in the horse industry and superior sires are used more intensely. Molecular genetic markers may be useful as early indicators for a stallion's fertility and genetic improvement programmes. The testis-specific SPATA1 protein is involved in shaping the sperm head during spermatogenesis. Thus, the spermatogenesis associated 1 (SPATA1) gene was chosen as candidate for stallion fertility, and we analysed intragenic single nucleotide polymorphisms (SNPs) as genetic markers for the least square means (LSM) of the pregnancy rate per oestrus of stallions and breeding values (BV) for the paternal and embryonic component of the pregnancy rate per oestrus. We sequenced the cDNA of SPATA1 to verify the annotated mRNA sequence. One SPATA1 -associated intronic SNP (BIEC2-968854) showed a significant association with the embryonic component of BVs of stallions for the pregnancy rate per oestrus. The embryonic component of BVs was positively associated with homozygous C/C stallions. Both the additive and dominance effects were significant with values of ,5.8% (P = 0.01) and ,6.4% (P = 0.02) for the embryonic component of BVs. For the same SNP, a suggestive association was found for the LSM of the pregnancy rate per oestrus of stallions. Heterozygous stallions had higher pregnancy rates per oestrus than homozygous stallions. The dominance effect was 4.1% with a nominal P -value of 0.02. The SNP BIEC2-968854 can change an SP1 binding site and thus we assume that gene regulation may be influenced through this intronic mutation. This is the first report on SPATA1 being associated with the pregnancy rate per oestrus for stallions. [source]

B-F DNA sequence variability in Brazilian (blue-egg Caipira) chickens

ANIMAL GENETICS, Issue 4 2004
C. A. V. Lima-Rosa
Summary A total of 100 chickens from the Brazilian (blue-egg Caipira) native breed were studied in relation to exon 2 of the B-F genes of the major histocompatibility complex (MHC) region. After a first screening on 100 birds, 22 animals were selected for amplification, cloning and sequencing experiments of exons 2,4 (a total of 1048 bp) of their DNA. Twenty-three sequences were obtained, of which at least 10 appear novel. Inferred protein sequences were compared with those previously described, totalling 41 different sequences with amino acid changes in 33 of the 88 sites in ,1, and 34 of the 91 sites in ,2 domains. Allele expression was investigated in these animals through cloning experiments. The blue-egg Caipira chickens may provide a source of novel B-F alleles for genetic improvement programmes. [source]

Genetic improvement in the Australian aquaculture industry

AQUACULTURE RESEARCH, Issue 1 2000
A J. Lymbery
Most aquaculture industries in Australia are at an early stage of development and would benefit from the introduction of genetic improvement programmes. Size at harvest is perceived by industry participants, managers and researchers as the trait that will most influence profitability. Although most current genetic improvement programmes in aquaculture use mass selection, inbreeding is widely regarded as an important problem, which could be overcome by the use of family data in selection decisions. The major research priority is the development of genetic markers to enable accurate pedigree determination. The major constraint upon the implementation of genetic improvement programmes by aquaculture industries is lack of available funds and resources. Industry ownership and national co-ordination of research and development is seen as the best way of addressing this constraint. [source]
