An unusual case of cutaneous listeriosis.

Listeria monocytogenes was identified as the etiological agent in the cutaneous and febrile illness of a 64-year-old male who acquired the organism as a result of contact with the genital tract of a cow while assisting in the delivery of a stillborn calf.     

Choice of Vein‐Harvest Technique for Coronary Artery Bypass Grafting: Rationale and Design of the REGROUP Trial

The Randomized Endo‐vein Graft Prospective (REGROUP) trial ( ClinicalTrials.gov  NCT01850082) is a randomized, intent‐to‐treat, 2‐arm, parallel‐design, multicenter study funded by the Cooperative Studies Program (CSP No. 588) of the US Department of Veterans Affairs. Cardiac surgeons at 16 Veterans Affairs (VA) medical centers with technical expertise in performing both endoscopic vein harvesting (EVH) and open vein harvesting (OVH) were recruited as the REGROUP surgeon participants. Subjects requiring elective or urgent coronary artery bypass grafting using cardiopulmonary bypass with use of ≥1 saphenous vein graft will be screened for enrollment using pre‐established inclusion/exclusion criteria. Enrolled subjects (planned N = 1150) will be randomized to 1 of the 2 arms (EVH or OVH) after an experienced vein harvester has been assigned. The primary outcomes measure is the rate of major adverse cardiac events (MACE), including death, myocardial infarction, or revascularization. Subject assessments will be performed at multiple times, including at baseline, intraoperatively, postoperatively, and at discharge (or 30 days after surgery, if still hospitalized). Assessment of leg‐wound complications will be completed at 6 weeks after surgery. Telephone follow‐ups will occur at 3‐month intervals after surgery until the participating sites are decommissioned after the trial's completion (approximately 4.5 years after the full study startup). To assess long‐term outcomes, centralized follow‐up of MACE for 2 additional years will be centrally performed using VA and non‐VA clinical and administrative databases. The primary MACE outcome will be compared between the 2 arms, EVH and OVH, at the end of the trial duration.     

Diffusion in gel-enzyme-linked immunosorbent assay—a new serological test for leptospirosis

A new serological test, diffusion in gel-enzyme-linked immunosorbent assay (DIG-ELISA) was developed and compared with the microscopic agglutination test (MAT) for the serological diagnosis of leptospirosis. The results suggest that DIG-ELISA is a viable alternative to the MAT because of its simplicity, sensitivity, versatility and potential for standardisation.     

FK506 in combination with methotrexate for the prevention of graft- versus-host disease after marrow transplantation from matched unrelated donors

The safety and potential efficacy of FK506 in combination with a short course of methotrexate (MTX) for the prevention of acute graft-versus- host disease (GVHD) after marrow transplantation from HLA-matched unrelated donors was evaluated in a single-arm Phase II study conducted at two centers. Forty-three patients, 15 to 54 (median 41) years of age, were transplanted for hematologic malignancies. Thirty-seven of 43 evaluable patients had evidence of sustained marrow engraftment. Five patients died before day 17 after transplantation. The median time to an absolute neutrophil count of > 0.5 x 10(5)/L was 21 (range, 14 to 30) days. Nephrotoxicity (serum creatinine concentration > 2 mg/dL or doubling of baseline) occurred in 32 patients (74% cumulative incidence during the first 100 days after transplant). Other adverse effects included hypertension (n = 27), hyperglycemia (n = 27), neurotoxicity (n = 9) and thrombotic thrombocytopenic purpura (n = 2). Severe veno- occlusive disease of the liver occurred in 9 (21%) of the 43 patients. Eighteen patients (42%) developed grades II to IV acute GVHD and five (12%) developed grades III to IV acute GVHD. Twelve of 25 evaluable patients developed extensive chronic GVHD within 1 year of marrow transplantation resulting in an estimate of the probability of developing this complication of 48%. The cumulative incidence of transplant-related mortality during the first 100 days was 37%. Kaplan- Meier estimates of disease-free survival at 2 years for good-risk, poor- risk, and all patients were 65%, 4%, and 32%, respectively. FK506 in combination with a short course of MTX appears active in preventing acute GVHD after marrow transplantation from unrelated donors. Further studies comparing the combination of FK506 and MTX with cyclosporine and MTX for the prevention of acute GVHD are warranted.     

EFFECTS OF ENALAPRIL AND HYDROCHLOROTHIAZIDE ON BLOOD PRESSURE, RENIN–ANGIOTENSIN SYSTEM, AND ATRIAL NATRIURETIC FACTOR IN ESSENTIAL HYPERTENSION: A DOUBLE BLIND FACTORIAL CROSS-OVER STUDY

The hypotensive and hormonal effects of the angiotensin converting enzyme (ACE) inhibitor enalapril (10 mg twice daily) were compared with those of hydrochlorothiazide (25 mg twice daily), with the two drugs in combination and with placebo in 21 patients with essential hypertension. For each patient there were four randomised double-blind treatment phases, each of four weeks' duration, which comprised a 2 times 2 factorial experiment.     

Recommendations for incorporating palliative care education into the acute care hospital setting.

This article presents recommendations for improving the education of physicians about end-of-life care in the acute care hospital setting. The authors, who have a variety of backgrounds and represent several types of institutions, formulated and reached consensus on these recommendations as members of the Acute Care Hospital Working Group, one of eight working groups convened at the National Consensus Conference on Medical Education for Care Near the End of Life in May 1997. A recently published literature review on the status of palliative care education, a summary of recent research on education about end-of-life care, and expert opinion were helpful in developing the recommendations. The authors emphasize that the acute care setting offers many opportunities for education about care at the end of life. Faculty should support learners' appreciation of the importance of end-of-life care, and convey the meaning and privilege of attending to patients and families at this difficult time. Faculty should teach students and residents to provide care that embodies attention to the control of distressing physical, physiologic, and spiritual symptoms, appropriate awareness of patients' differing cultural backgrounds and their impact upon the experience of dying, excellent communication skills, the application of bioethical principles, timely referral and smooth transition to other care settings that meet patient and family goals, and the role of the interdisciplinary team in meeting the diverse needs of dying patients and their families.
