Correlates of treatment satisfaction and well-being among patients with type II diabetes.

AIM: To examine the impact of patient characteristics, anthropometric measurement and patient clinical variables on their appraisal of treatment satisfaction and well-being. BACKGROUND: Treatment satisfaction and well-being are instrumental in achieving diabetes care goals. Nursing practices and healthcare policies may inform interventions in these areas. INTRODUCTION: The prevalence of diabetes is high in the Middle East. An understanding of relationships between clinical and socio-demographic variables and well-being and treatment satisfaction is needed to improve care and patient outcomes. METHODS: A total of 1002 patients completed tools measuring well-being, treatment satisfaction and socio-demographic characteristics. A series of bivariate and multivariate analysis were conducted to identify factors associated with well-being and treatment satisfaction. RESULTS: Males reported better treatment satisfaction and well-being than females. Older participants, those who were compliant to diet, with controlled diabetes, and no neuropathy reported higher treatment satisfaction scores and well-being scores. Insulin therapy was associated with better treatment satisfaction. DISCUSSION: Females, participants who were not prescribed diabetic diets and those with complications were more likely to be negatively impacted by diabetes. Individuals with diabetes who were treated with insulin had higher treatment satisfaction than those who used oral hypoglycaemic agents. CONCLUSION AND IMPLICATION FOR NURSING AND HEALTH POLICY: These findings are important in assisting nurses and other healthcare professionals in identifying patients with diabetes with low treatment satisfaction who may present a greater risk for poor well-being. Additionally, they lend support to developing policies for frequent screenings and special therapeutic interventions that are needed to maximize patients' treatment satisfaction and well-being in the Middle East and elsewhere.

Impact of a clonal outbreak of extended-spectrum ß-lactamase-producing Klebsiella pneumoniae in the development and evolution of bloodstream infections by K. pneumoniae and Escherichia coli: an 11 year experience in Oxfordshire, UK.

OBJECTIVES: The objectives of this study were: (i) to describe an outbreak of multidrug-resistant Klebsiella pneumoniae in our population; (ii) to identify the potential source of this outbreak by examining antibiotic resistance trends in urocultures; (iii) to evaluate the contribution of this outbreak to resistance patterns over time in the two commonest Gram-negative blood culture isolates, namely K. pneumoniae and Escherichia coli; and (iv) to assess risk factors for multidrug resistance and the impact of this resistance on mortality and length of stay. METHODS: We searched Microbiology and Patient Administration Service databases retrospectively and describe resistance trends in E. coli and K. pneumoniae bloodstream infections (BSIs) in Oxfordshire, UK, over an 11 year period. RESULTS: An outbreak of a multidrug-resistant, CTX-M-15 extended-spectrum ß-lactamase (ESBL)-producing K. pneumoniae clone was identified and shown by multilocus sequence typing to belong to a novel sequence type designated ST490. This was associated with a sporadic change in resistance rates in K. pneumoniae BSIs with rates of multidrug resistance (defined as resistance to three or more antibiotic classes) reaching 40%. A case-control study showed prior antibiotic exposure as a risk factor for infection with this organism. During the same time period, rates of ESBL-producing Klebsiella spp. isolated from urocultures increased from 0.5% to almost 6%. By contrast, the rate of multidrug resistance in E. coli rose more steadily from 0% in 2000 to 10% in 2010. CONCLUSIONS: Changes in resistance rates may be associated with outbreaks of resistant clones in K. pneumoniae. Changing resistance patterns may affect important health economic issues such as length of stay.

Alpha-B crystallin gene (CRYAB) mutation causes dominant congenital posterior polar cataract in humans.

Congenital cataracts are an important cause of bilateral visual impairment in infants. In a four-generation family of English descent, we mapped dominant congenital posterior polar cataract to chromosome 11q22-q22.3. The maximum LOD score, 3.92 at recombination fraction 0, was obtained for marker D11S898, near the gene that encodes crystallin alpha-B protein (CRYAB). By sequencing the coding regions of CRYAB, we found in exon 3 a deletion mutation, 450delA, that is associated with cataract in this family. The mutation resulted in a frameshift in codon 150 and produced an aberrant protein consisting of 184 residues. This is the first report of a mutation, in this gene, resulting in isolated congenital cataract.
