Selected AbstractsPsychosocial adjustment of female partners of men with prostate cancer: a review of the literaturePSYCHO-ONCOLOGY, Issue 11 2006Jeremy Couper Abstract Advances in prostate cancer treatments since the 1990s have led to a growing proportion of patients living with the effects of the cancer. Various challenges face the man and his partner from the point of learning of the diagnosis: deciding among numerous diverse treatment options, dealing with side-effects of treatment and possibly facing the terminal phase of the illness. This invariably has an impact on the patient's family and, in view of the older age group of men usually affected, the experience of a partner is particularly relevant. A thorough review of the research literature reporting directly from partners of prostate cancer patients has not been undertaken previously. For this review, five databases were searched for the decade 1994,2005, during which most of the work in this field has been done. Very few evaluations of psychosocial interventions involving the partner were found, but there was a preponderance of qualitative studies involving small numbers of participants and quantitative surveys with little consistency in the measures used. The literature suggests that partners report more distress than patients, yet believe that patients are the more distressed, and the focus of concern of patients on their sexual function is not shared to an equal degree by their partners.

Ann Easterbrooks The aim of this study was to examine patterns of emotional availability among 80 young mothers (under 21 years at their child's birth) and their infants, and to identify contextual and individual factors associated with different patterns of emotional availability. To operationalize the dyadic aspect of emotional availability, cluster analysis of the Emotional Availability Scales, third edition (EAS; Biringen, Robinson, & Emde, 1998) was conducted on mother and infant scales simultaneously. Four distinct groups of emotional availability patterns emerged, reflecting synchrony and asynchrony between maternal and child behavior: (a) low-functioning dyads, (b) average dyads, (c) average parenting/disengaged infants, and (d) high-functioning dyads. Further analyses revealed that mothers in different clusters differed on outcomes such as depressive symptomatology, social support, and relationships with their own mothers. The clusters and the variables related to them demonstrate the various challenges in integrating the dual tasks of adolescent and parenting development among young mothers. The clinical implications of these patterns of emotional availability and live context are discussed. [source] Clients' perceptions of support received from health visitors during home visitsJOURNAL OF CLINICAL NURSING, Issue 7 2005Caroline Plews BA Aims and objectives., The current study sought to identify how many mothers from 149 visits carried out by seven health visitors identified support as a feature of the visit, whether this type of support was unique to the health visitor and what support meant to them. These responses were then compared with the taxonomies of social support from the social support literature. Background., Some studies of client perceptions describe support as an element of home visits by health visitors. However, the importance, relevance and impact on the client of this support are not described in detail. Social support theory suggests that there are tangible benefits to people's well-being and their ability to cope with various challenges that may arise from individuals' perceptions of receiving support. Design., Qualitative study using semistructured interviews. Methods., Seven volunteer health visitors recruited 149 women into the study. These clients were interviewed by the researcher, usually within one week of the home visit by their health visitor. The discussions were audio-taped and the resulting transcripts analysed using content analysis. Findings., Thirty-seven women identified receiving support which they said was only available from the health visitor. The relevance of this support to the mother and the impact on her well-being varied within the group suggesting differing perceptions of support by clients according to their personal situation. There was a correspondence between the descriptions of support given by the women and the taxonomies of social support from the social support literature. Conclusion., For some interactions between clients and their health visitors the existing theory of social support may provide an explanation of how health visitors contribute to clients' perceived ability to cope and well-being. Relevance to clinical practice., Social support may be defined as a possible outcome of health visiting. This concept will have use within educational programmes to demonstrate to students how health visiting can have an impact on clients' well-being. Similarly, the concept could be used to investigate and record health visiting practice. [source] Central Bank Independence: An Update of Theory and EvidenceJOURNAL OF ECONOMIC SURVEYS, Issue 1 2001Helge Berger This paper reviews recent research on central bank independence (CBI). After we have distinguished between independence and conservativeness, research in which the inflationary bias is endogenised is reviewed. Finally, the various challenges that have been raised against previous empirical findings on CBI are discussed. We conclude that the negative relationship between CBI and inflation is quite robust. [source] Advances in Campylobacter biology and implications for biotechnological applicationsMICROBIAL BIOTECHNOLOGY, Issue 3 2010Byeonghwa Jeon Summary Campylobacter jejuni is a major foodborne pathogen of animal origin and a leading cause of bacterial gastroenteritis in humans. During the past decade, especially since the publication of the first C. jejuni genome sequence, major advances have been made in understanding the pathobiology and physiology of this organism. It is apparent that C. jejuni utilizes sophisticated mechanisms for effective colonization of the intestinal tracts in various animal species. Although Campylobacter is fragile in the environment and requires fastidious growth conditions, it exhibits great flexibility in the adaptation to various habitats including the gastrointestinal tract. This high adaptability is attributable to its genetically, metabolically and phenotypically diverse population structure and its ability to change in response to various challenges. Unlike other enteric pathogens, such as Escherichia coli and Salmonella, Campylobacter is unable to utilize exogenous glucose and mainly depends on the catabolism of amino acids as a carbon source. Campylobacter proves highly mutable in response to antibiotic treatments and possesses eukaryote-like dual protein glycosylation systems, which modify flagella and other surface proteins with specific sugar structures. In this review we will summarize the distinct biological traits of Campylobacter and discuss the potential biotechnological approaches that can be developed to control this enteric pathogen. [source] Antiretroviral therapy adherence among patients living with HIV/AIDS in ThailandNURSING & HEALTH SCIENCES, Issue 2 2010Li Li phd Abstract The importance of antiretroviral therapy adherence for patients living with HIV/AIDS has been well documented. Despite this critical need, many do not follow prescribed regimens. To examine the barriers that lead to non-adherence, we used cross-sectional survey data from a randomized controlled intervention trial in northern and north-eastern Thailand. Of the 507 patients that were enrolled in the trial, we analyzed 386 patients on antiretroviral therapy in order to examine the barriers to adherence. In addition to demographic characteristics, depressive symptoms, physical health, access to care, social support, and internalized shame, HIV disclosure and family communication were examined. The correlation analysis revealed that adherence is significantly associated with internalized shame, access to care, depressive symptoms, and family communication. Based on the multiple logistic regression analysis, depressive symptoms, access to care, HIV disclosure, and family communication were significant predictors of adherence. Having depressive symptoms remains a significant barrier to adherence, while access to care, HIV disclosure, and family communication play important positive roles. Our findings underscore the critical importance of addressing these various challenges that can influence adherence to antiretroviral therapy. [source] The Effects of Potentiality Education on Potentiality and Job Satisfaction Among Psychiatric Nurses in TaiwanPERSPECTIVES IN PSYCHIATRIC CARE, Issue 2 2010Kang-Hua Chen RN PURPOSE., This study evaluated the effects of a potentiality education program on potentiality and job satisfaction among psychiatric nurses. DESIGN AND METHODS., This quasiexperimental study recruited 59 psychiatric nurses, of whom 26 were assigned to an experimental group, based on their interest in participating in the program, and 33 to a control group. FINDINGS., The results indicated that the scores for job satisfaction were significantly higher in the experimental group than in the control group. Specifically, potentiality education promoted job satisfaction but had no significant influence on potentiality. PRACTICE APPLICATION., Increasing nurses' potentiality could help them to successfully cope with their large workload and the various challenges of their job. [source] Developing a performance measurement framework to enhance the impact orientation of the Food Research Institute, GhanaR & D MANAGEMENT, Issue 2 2006Robert M. Yawson Research institutions in Ghana are facing various challenges. It is the contention that viable research and development institutions are needed for achieving sustainable change in areas of national importance. A key aspect of institutional viability is strong performance management. This implies clear and workable approaches to performance measurement. This paper looks at the initial experiences in a collaborative effort to develop a performance measurement framework for the Food Research Institute (FRI) and the application of the Balanced Score Card (BSC) at institutional level. The process of diagnosing and analysing institutional monitoring and evaluation capacity and systems is described using a mix of diagnostic tools. Stages in applying the BSC approach are documented and the added value of the scorecard perspectives in highlighting focal areas for performance measurement and management within FRI. These are placed in the context of ongoing changes in the external environment posing both threats and opportunities. Changes implied by the introduction of the concept are discussed in the context of current constraints and the way forward is mapped out in terms of enhancing FRIs' impact orientation through the application of improved performance measurement and management. [source] Application of the operating window concept to remediation-option selectionREMEDIATION, Issue 3 2004Duncan I. Scott An Erratum has been published for this article in Remediation 14(4) 2004, 141. The selection of remediation options for the management of unacceptable risks at contaminated sites is hindered by insufficient information on their performance under different site conditions. Therefore, there is a need to define "operating windows" for individual remediation options to summarize their performance under a variety of site conditions. The concept of the "operating window" has been applied as both a performance optimization tool and decision support tool in a number of different industries. Remediation-option operating windows could be used as decision support tools during the "options appraisal" stage of the Model Procedures (CLR 11), proposed by the Environment Agency (EA) for England and Wales, to enhance the identification of "feasible remediation options" for "relevant pollutant linkages." The development of remediation-option operating windows involves: 1) the determination of relationships between site conditions ("critical variables") and option performance parameters (e.g., contaminant degradation or removal rates) and 2) the identification of upper- and lower-limit values ("operational limits") for these variables that define the ranges of site conditions over which option performance is likely to be sufficient (the "operating window") and insufficient (the "operating wall") for managing risk. Some research has used case study data to determine relationships between critical variables and subsurface natural attenuation (NA) process rates. Despite the various challenges associated with the approach, these studies suggest that available case study data can be used to develop operating windows for monitored natural attenuation (MNA) and, indeed, other remediation options. It is envisaged that the development of remediation-option operating windows will encourage the application of more innovative remediation options as opposed to excavation and disposal to landfill and/or on-site containment, which remain the most commonly employed options in many countries. © 2004 Wiley Periodicals, Inc. [source] Chronic disease profiles in remote Aboriginal settings and implications for health services planningAUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 1 2010Wendy E. Hoy Abstract Objective: To report the short-term experiences and outcomes of a program to support chronic disease management in three remote communities in Top End Northern Territory and in two Aboriginal Medical Services (AMSs) in Western Australia, and to discuss the implications of findings for health service delivery and policy. Methods: Programs were health-worker centred. They espoused regular screening of all adults for chronic disease, initiation and modification of treatment where indicated and rigorous documentation. Process measures were documented and rates of hypertension, renal disease and diabetes among adults were calculated. Results: Rates of hypertension, proteinuria and diabetes rose throughout adult life and multiple diagnoses were common. Most people with these conditions were young or middle age adults. Rates were uniformly excessive relative to AusDiab data, but varied greatly among settings. Adherence to protocols improved, many new diagnoses were made, treatments were started or modified and blood pressures in treated hypertensive people fell. In the NT, productivity was seriously limited by lack of health workers and their absenteeism. In the WA AMSs, executive and staff support carried the programs forward to a sustainable future, despite various challenges. Conclusions: Integrated chronic disease testing must be repeated throughout adult life for timely diagnosis. Health workers can perform all tasks well, with appropriate supports. Blood pressure outcomes alone predict lower cardiovascular and renal mortality. The findings support incorporation of chronic disease into lifetime health care plans. [source] Problems of Fit: Changing Employment and Labour RegulationBRITISH JOURNAL OF INDUSTRIAL RELATIONS, Issue 4 2004Linda Dickens This paper indicates key issues in identifying and assessing change in the employment relationship. It explores various challenges that the changing shape of employment poses for both legal regulation and regulation provided through collective bargaining. It suggests different rationales for seeking a better fit and discusses various adjustments and changes to achieve this. Finally, I argue that problems of fit (misfit), and the need for adaptation to which this gives rise, are relevant also to the study of industrial relations. [source] Most readily usable methods to measure ocular blood flowACTA OPHTHALMOLOGICA, Issue 2009K GUGLETA Purpose SIS Lecture. Methods Literature search. Results Ocular Blood Flow Research Association (OBFRA, recently merged with another organization - ISOCO, into one single Association for Ocular CDirculation - AOC) made a significant contribution to standardization of the blood flow measuring techniques in the field of ophthalmology. A consens was reached on the number of OBF measurements techniques that occured in the past decades. Particular emphasis was placed on the basic technology, specific parameters and interpretation, accuracy and reproducibility, field of clinical applications. Open questions were extensively discussed, limits of each technique clearly postulated. and a consensus statement put together for each of the technique involved. It encompassed techniques like color Doppler imaging, laser Doppler flowmetry (continuous as well as scanning LDF), laser Doppler velocimetry, Retinal Vessel Analyzer, combination of the vessel diameter measurement and the LDV, laser interferometry of the fundus pulsations amplitude, retinal oxymetry, measurements of the pulsatile component of the blood flow, blue field entoptic method and the newest - Doppler OCT. Conclusion There is no overwhelming measuring technique able to cover all the aspects of the research and the daily clinical routine. Various parameters and various vascular beds are involved, which makes the interpretation of the obtained results strenuous. Of particular importance is the capability of OBF measuring techniques to capture one dynamic feature of ocular circulation - its ability to regulate and to response to various challenges. It is widely believed that not the constantly reduced blood flow, but rather the lack of regulation thereof, leads to prevalent ocular diseases. [source] | |||||||||||||
