Abstract

OBJECTIVE: Differences in type 2 diabetes phenotype by age are described, but it is not known whether these differences are seen in a more uniformly defined adult population at a common early stage of care. We sought to characterize age-related clinical and metabolic characteristics of adults with type 2 diabetes on metformin monotherapy, prior to treatment intensification. RESEARCH DESIGN AND METHODS: In the Glycemia Reduction Approaches in Diabetes: A Comparative Effectiveness Study (GRADE), participants were enrolled who had type 2 diabetes duration

Abstract

The graphic capabilities of the IBM PC can be enhanced with BASIC subroutines called Q-Graphics. The name reflects the fact that all the variables in the subroutines start with the letter Q, so as not to duplicate program variables. Q-graphic routines allow the user to create a 'window' (an area on the screen) where all commands and reference points only relate to that area, and allow various graphing techniques to be implemented. Drawings, charts, and a complete program listing are included.

6. Effect of Corynebacterium granulosum immunopotentiation on the pathogenesis of herpes simplex virus type 2 in BALB/c mice

Author

Gabrielson, D A, Kelleher, J J, and Varani, J

Abstract

Treatment of 4- to 6-week-old, 18- to 22-g male BALB/c mice with 0.6 mg of Corynebacterium granulosum resulted in a significant decrease in mortality due to challenge with herpes simplex virus type 2 (HSV-2). Optimal protection occurred when C. granulosum was injected 1 week before HSV-2 infection. C. granulosum-induced resistance to HSV-2 lasted up to 4.5 weeks. Studies involving immune spleen cell transfer and treatment with antilymphocyte serum demonstrated the importance of cell-mediated immunity in HSV-2 infection. However, C. granulosum protection was not transferable with spleen cells from C. granulosum-treated animals nor was C. granulosum treatment capable of completely overcoming the increased mortality which resulted from antilymphocyte serum treatment of HSV-2 infected mice. Under our experimental conditions, silica did not affect the mortality in BALB/c mice due to HSV-2 but significantly reduced the protective effects induced by C. granulosum. Attempts to transfer protection of HSV-2 challenge in suckling mice by using either glass-adherent or mixed peritoneal cells from either HSV-2-immunized or C. granulosum-treated animals were unsuccessful.

7. Simple hemagglutination inhibition test for the diagnosis of toxoplasmosis

Author

Chang, G N, Nemzek, J A, Tjostem, J L, and Gabrielson, D A

Abstract

A simple hemagglutination inhibition (HI) test for the serological diagnosis of toxoplasmosis has been developed and evaluated. A total of 84 human and 120 mouse serum samples were tested by the newly developed HI test and compared with an immunoglobulin G-indirect fluorescent antibody test. Statistical analysis of serum titers obtained by using the HI test and the immunoglobulin G-indirect fluorescent antibody test showed a correlation coefficient of 0.89. The diagnostic efficacy of HI when compared with the immunoglobulin G-indirect fluorescent antibody diagnostic test results was 96.43% for human sera and 100% for mouse sera. The unique hemagglutination antigen, derived from Toxoplasma gondii (Rh strain) exotoxin, spontaneously binds with mouse or rat erythrocytes, causing the hemagglutination reaction. In this study, 2, 4, or 8 hemagglutinating units of T. gondii exotoxin was used with Swiss/Webster mouse erythrocytes as an indicator for the HI assay. The results indicate that 8 hemagglutinating units is optimal because this concentration has the least unexplained variability. T. gondii exotoxin was stable for at least 18 months at -70 degrees C. The Toxoplasma HI test we report in this paper is shown to be a fast, easy, highly specific, and sensitive test for the diagnosis of toxoplasmosis.

8. Best Practices for Managing Patients with Unresectable Metastatic Gastric and Gastroesophageal Junction Cancer in Canada.

Abstract

Gastric cancer (GC) is one of the most common types of cancer and is associated with relatively low survival rates. Despite its considerable burden, there is limited guidance for Canadian clinicians on the management of unresectable metastatic GC and gastroesophageal junction cancer (GEJC). Therefore, we aimed to discuss best practices and provide expert recommendations for patient management within the current Canadian unresectable GC and GEJC landscape. A multidisciplinary group of Canadian healthcare practitioners was assembled to develop expert recommendations via a working group. The often-rapid progression of unresectable GC and GEJC and the associated malnutrition have a significant impact on the patient's quality of life and ability to tolerate treatment. Hence, recommendations include early diagnosis, identification of relevant biomarkers to improve personalized treatment, and relevant support to manage comorbidities. A multidisciplinary approach including early access to registered dietitians, personal support networks, and palliative care services, is needed to optimize possible outcomes for patients. Where possible, patients with unresectable GC and GEJC would benefit from access to clinical trials and innovative treatments.

Abstract

Severe acute respiratory syndrome (SARS), a new, highly contagious, viral disease, emerged in China late in 2002 and quickly spread to 32 countries and regions causing in excess of 774 deaths and 8098 infections worldwide. In the absence of a rapid diagnostic test, therapy or vaccine, isolation of individuals diagnosed with SARS and quarantine of individuals feared exposed to SARS virus were used to control the spread of infection. We examine mathematically the impact of isolation and quarantine on the control of SARS during the outbreaks in Toronto, Hong Kong, Singapore and Beijing using a deterministic model that closely mimics the data for cumulative infected cases and SARS-related deaths in the first three regions but not in Beijing until mid-April, when China started to report data more accurately. The results reveal that achieving a reduction in the contact rate between susceptible and diseased individuals by isolating the latter is a critically important strategy that can control SARS outbreaks with or without quarantine. An optimal isolation programme entails timely implementation under stringent hygienic precautions defined by a critical threshold value. Values below this threshold lead to control, but those above are associated with the incidence of new community outbreaks or nosocomial infections, a known cause for the spread of SARS in each region. Allocation of resources to implement optimal isolation is more effective than to implement sub-optimal isolation and quarantine together. A community-wide eradication of SARS is feasible if optimal isolation is combined with a highly effective screening programme at the points of entry.

Abstract

Immunoglobulins were isolated and purified from the colostrum and serum of progressive pneumonia virus infected sheep and also from non-infected control sheep. Four classes of immunoglobulins were isolated from sheep colostrum (IgG1, IgG2, IgA and Ig10s). Three classes of immunoglobulins were isolated from sheep serum (IgG1, IgG2 and IgM). Low levels of virus neutralizing activity were demonstrated only in the whole serum and purified serum IgG1 preparations. No complement fixing activity was detected in any of the antibody preparations from colostrum.

Abstract

One hundred ninety-six (196) animal sera were examined for antibodies against heat-killed antigens of Legionella pneumophila serogroups 1 to 5, L. bozemanii, L. dumoffii, L. gormanii and L. micdadei by the indirect fluorescent antibody technique. Only two animals (1%), both sheep, reacted against L. pneumophila serogroups at a titer of 256. However, 29% of the horses and 24% of the sheep tested were reactive to at least one non-L. pneumophila Legionella spp. antigen at a titer of 256. At a titer of 128, 72% of the pigs, 56% of the sheep and 50% of the horses were reactive to at least one Legionella spp. antigen. Despite the presence of high antibody titers against Legionella antigens, conclusive evidence of infection by these agents in animals is dependent upon further studies.
