ABSTRACT

INTRODUCTION: Patient safety is a value at the core of modern healthcare. Though awareness in the medical community is growing, implementing systematic approaches similar to those used in other high reliability industries is proving difficult. The aim of this research was twofold, to establish a baseline for patient safety practices on routine ward rounds and to test the feasibility of implementing an electronic patient safety checklist application. METHODS: Two research teams were formed; one auditing a medical team to establish a procedural baseline of "usual care" practice and an intervention team concurrently was enforcing the implementation of the checklist. The checklist was comprised of eight standard clinical practice items. The program was conducted over a 2-week period and 1 month later, a retrospective analysis of patient charts was conducted using a global trigger tool to determine variance between the experimental groups. Finally, feedback from the physician participants was considered. RESULTS: The results demonstrated a statistically significant difference on five variables of a total of 16. The auditing team observed low adherence to patient identification (0.0%), hand decontamination (5.5%), and presence of nurse on ward rounds (6.8%). Physician feedback was generally positive. CONCLUSIONS: The baseline audit demonstrated significant practice bias on daily ward rounds which tended to omit several key-proven patient safety practices such as prompting hand decontamination and obtaining up to date reports from nursing staff. Results of the intervention arm demonstrate the feasibility of using the Checklist App on daily ward rounds.

ABSTRACT

Glycerol kinase (GK) represents the primary entry of glycerol into glucose and triglyceride metabolism. Impaired glucose tolerance (IGT) and hypertriglyceridemia are associated with an increased risk of diabetes mellitus and cardiovascular disease. The relationship between glycerol and the risk of IGT, however, is poorly understood. We therefore undertook the study of fasting plasma glycerol levels in a cohort of 1,056 unrelated men and women of French-Canadian descent. Family screening in the initial cohort identified 18 men from five families with severe hyperglycerolemia (values above 2.0 mmol/liter) and demonstrated an X-linked pattern of inheritance. Linkage analysis of the data from 12 microsatellite markers surrounding the Xp21.3 GK gene resulted in a peak LOD score of 3.46, centered around marker DXS8039. In addition, since all of the families originated in a population with a proven founder effect-the Saguenay Lac-St.-Jean region of Quebec-a common disease haplotype was sought. Indeed, a six-marker haplotype extending over a region of 5.5 cM was observed in all families. Resequencing of the GK gene in family members led to the discovery of a N288D missense mutation in exon 10, which resulted in the substitution of a highly conserved asparagine residue by a negatively charged aspartic acid. Although patients with the N288D mutation suffered from severe hyperglycerolemia, they were apparently otherwise healthy. The phenotypic analysis of the family members, however, showed that glycerol levels correlated with impaired glucose metabolism and body-fat distribution. We subsequently noted a substantial variation in glycerolemia in subjects of the initial cohort with normal plasma glycerol levels and demonstrated that this variance showed significant family resemblance. These results suggest a potentially important genetic connection between fasting glycerolemia and glucose homeostasis, not only in this X-linked deficiency but, potentially, in individuals within the "normal" range of plasma glycerol concentrations.

ABSTRACT

The collection of familial data is an essential step for community genetics programs or genetic research. Ethical issues concerning privacy and confidentiality present a major challenge in such programs. In order to keep familial data confidential, we have developed a family-based numerical coding procedure which allows the use of confidential data and the determination of familial relationships without risk of disclosure. This procedure is composed of two parts: the physical separation of identifying information and individual data; and the use of a code containing all the information required to build family trees. This procedure has been used in Eastern Quebec since 1995, mainly for screening, genetic counseling, research on familial dyslipidemias, public health intervention, and research projects on the genetics of complex traits, such as arterial hypertension and coronary artery disease.

ABSTRACT

Short peptides often do not bind well to the plastic surface of microtitre wells in solid-phase immunoassays. To improve the reactivity of synthetic peptides coated on the solid phase, we have developed a highly sensitive, rapid and simple ELISA. This ELISA is based on the treatment of microtitre plates with Alcian blue prepared in acetic acid prior to coating the target peptide. With hyperimmune serum, this treatment increases the specific signal in such a manner that the detection of antibodies needs less antigen than with conventional ELISA. Moreover, the Alcian blue treatment was shown to be particularly effective for the detection of monoclonal antibodies against a synthetic peptide derived from the human immunodeficiency type 1 (HIV-1) vpu protein. These monoclonal antibodies that were not detected in conventional ELISA gave a positive signal up to a 1 in 1000 dilution after Alcian blue treatment of microtitre wells. This assay should be applicable to a variety of synthetic peptides and other types of molecules posing problems in assays requiring their immobilization on solid phases.
