Glucose potassium insulin infusions in the treatment of acute stroke patients with mild to moderate hyperglycemia: the Glucose Insulin in Stroke Trial (GIST).

BACKGROUND AND PURPOSE: Hyperglycemia following acute stroke is strongly associated with subsequent mortality and impaired neurological recovery, but it is unknown whether maintenance of euglycemia in the acute phase improves prognosis. Furthermore, the safety of such intervention is not established. METHODS: In an explanatory, randomized, controlled trial to test safety, 53 acute (within 24 hours of ictus) stroke patients with mild to moderate hyperglycemia (plasma glucose between 7.0 and 17.0 mmol/L) were randomized to receive either a 24-hour infusion of 0.9% (154 mmol/L) saline or a glucose potassium insulin (GKI) infusion at 100 mL/h. The GKI consisted of 16 U human soluble insulin and 20 mmol potassium chloride in 500 mL 10% glucose. Blood glucose was measured every 2 hours with Boehringer Mannheim Glycaemie test strips, pulse and blood pressure were measured every 4 hours, and plasma glucose samples were taken every 8 hours. Insulin concentration in the GKI was altered according to BM glucose values. RESULTS: There were no statistically significant differences between the 2 groups at baseline. Twenty-five patients received GKI, 1 of whom required intravenous glucose for symptomatic hypoglycemia. Plasma glucose levels were nonsignificantly lower in the GKI group throughout the infusion period. Four-week mortality in the GKI group was 7 (28%), compared with 8 (32%) in the control group. CONCLUSIONS: GKI infusions can be safely administered to acute stroke patients with mild to moderate hyperglycemia producing a physiological but attenuated glucose response to acute stroke, the effectiveness of which remains to be elucidated.

The need for specialized training programs in palliative medicine.

Canada faces a significant and growing burden of terminal illness. There are major unresolved economic, ethical and social issues related to care at the end of life. Despite the international reputation for Canadian efforts in palliative care, the medical profession in Canada has largely failed to recognize the importance of the field, as evidenced by the lack of commitment on the part of most medical faculties at Canadian universities to developing academic strength in palliative medicine, the lack of content in the undergraduate curriculum and of postgraduate programs in palliative medicine, and the lack of support for research into end-of-life care. The authors propose a conjoint initiative by the Royal College of Physicians and Surgeons of Canada and the College of Family Physicians of Canada to develop specialized training programs in palliative medicine as a critical step in addressing this crisis.

The Canadian Palliative Care Undergraduate Curriculum.

In 1988 the deans of 12 (out of 16) Canadian medical schools appointed representatives to a Canadian Palliative Care Curriculum Committee. The Committee has subsequently published the Canadian Palliative Care Curriculum which outlines specific goals and objectives for palliative care instruction in undergraduate medical teaching. The Curriculum covers 22 different topics, including 13 symptoms and 9 psychosocial issues. The Canadian Curriculum Committee continues to meet and is now considering other national educational initiatives in palliative care.

Primary care providers' perceptions of care.

The Regional Palliative Care Unit in Ottawa conducted a retrospective study to determine how satisfied patients and families were with the service the Unit offers. Forty-five primary care providers, bereaved from 6 to 12 months, completed the 64-item semistructured telephone interview in a mean time of 20 minutes. The 59 closed-ended questions rated satisfaction levels concerning various aspects of the palliative care service on a 5-point Likert scale. Five open-ended questions elicited family priorities and suggestions for improvement. The major finding was that care was perceived to be highly satisfactory. Unexpected outcomes of the study were the identification by family members of the criteria for a "good death" and families' perceptions that the Unit offers the best quality of life and death even for those patients who resist admission to the hospice setting.

Anti-fluorescein antibody 3-13 VH gene rearrangement in idiotypically cross-reactive hybridomas.

The deduced amino acid sequence of anti-fluorescein (F1) antibody 3-13 VH region (residues 1-95) was 78% homologous to the alpha-1----3-dextran binding myeloma protein J558 VH region and was in the Wu-Kabat Subgroup II or Dildrop Group I classifications. The 3-13 VH region was rearranged to a D segment with only 8 of 30 bp in common with DFL16.1 germ line D gene and less homologous to all other previously identified D sequences. This sequence was joined to the third codon of JH4. The sequence encoding VH residues 5-91 was subcloned into pSP65 and used as a probe in Southern analyses to monitor 3-13 VH gene rearrangements in 12 other anti-F1 hybridomas differentially expressing (or not at all) the 3-13 idiotype. Three clones which inhibited the 3-13 idiotype-anti-idiotype interaction as effectively as 3-13 (3-12, 3-17 and 3-35), all had rearranged a gene which hybridized to the cloned 3-13 fragment, however, each was contained on a different size restriction fragment. Analyses of five other idiotypically related (but not identical) hybridomas indicated that four had rearranged a cross hybridizing VH gene while no such rearrangements were detected among four idiotypically negative cell lines. A restriction site assay indicated five clones examined had all rearranged a Vk gene to the Jk1 or Jk2 gene segment. The sequence of the antibody 3-13 VH gene and its use in hybridization studies represent the first molecular analysis of a recurrently expressed repertoire specific idiotype within an unrestricted immune response.
